Item 1.01. Entry into a Material Definitive Agreement.

Merger Agreement

On July 30, 2014, GFI Group Inc., a Delaware corporation (the “Company” or “GFI”), CME Group Inc., a Delaware corporation (“CME”), Commodore Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of CME (“Merger Sub 1”), and Commodore Acquisition LLC, a Delaware limited liability company and a wholly-owned subsidiary of CME (“Merger Sub 2”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) providing for the merger of Merger Sub 1 with and into the Company (the “Merger”), with the Company continuing as the surviving corporation in the Merger (the “Surviving Corporation”), which will be followed, immediately after the effective time of the Merger (the “Effective Time”), by a merger of the Surviving Corporation with and into Merger Sub 2 (the “Subsequent Merger” and, together with the Merger, the “Combination”), with Merger Sub 2 continuing as the surviving entity in the Subsequent Merger. As a result of the Merger, Merger Sub 2 will become a wholly-owned subsidiary of CME.

At the Effective Time, by virtue of the Merger and without any action on the part of the holders of any shares of the capital stock of the Company, each share of GFI common stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive a fraction of a share (the “Exchange Ratio”) of CME Class A common stock (“CME Class A Common Stock”). The Exchange Ratio is a fraction, the numerator of which equals $4.55 and the denominator of which equals the average closing sales price of CME Class A Common Stock as reported on the NASDAQ Global Select Market for the ten trading days ending upon and including the trading day immediately before the closing date of the Merger. In connection with the Merger, CME will assume $240 million in outstanding debt of the Company.

Any GFI restricted stock units outstanding immediately before the Effective Time held by any employee that remains employed by CME or any of its subsidiaries (a “Continuing Employee”) following the consummation of the IDB Transaction (as defined below) shall be converted at the Effective Time into an obligation of CME or its subsidiaries. Any GFI restricted stock units outstanding immediately before the Effective Time held by any employee other than a Continuing Employee or a non-employee director of the Company shall be converted into an obligation of IDB Buyer (as defined below). Each outstanding GFI option will be canceled as of the Effective Time for no consideration.

The Merger Agreement was approved by a unanimous vote of the Company’s board of directors (the “Company Board”), acting upon the unanimous recommendation of the special committee composed of independent directors of the Company Board (the “Special Committee”). Mr. Michael Gooch, the Company’s Executive Chairman, and Mr. Colin Heffron, the Company’s Chief Executive Officer, recused themselves from the vote on the Merger. All other members of the Company Board voted in favor of approving the Merger Agreement. In connection with the Special Committee’s recommendation, Greenhill & Co., LLC, as financial advisor to the Special Committee, rendered its opinion to the Special Committee that, as of the date of the opinion and subject to the various assumptions and qualifications set forth therein, the Exchange Ratio is fair, from a financial point of view, to the holders of GFI common stock.

The consummation of the Combination is subject to customary closing conditions, including, without limitation, (i) obtaining the approval of GFI stockholders, including the affirmative vote of a majority of the disinterested GFI stockholders, (ii) the shares of CME Class A Common Stock to be issued in the Merger being approved for listing on NASDAQ, (iii) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and any other waiting periods under certain specified foreign competition laws, receipt of other specified regulatory approvals and the provision of certain notices to third parties, (iv) the absence of any law or order that is in effect and restrains, enjoins or otherwise prohibits the Combination, (v) the registration statement to be filed by CME with respect to the shares of CME Class A Common Stock to be issued in the Merger being declared effective by the Securities and Exchange Commission, (vi) the completion of a pre-closing reorganization of the Company, and the satisfaction or waiver of the conditions to closing of the JPI Merger Agreement and the IDB Purchase Agreement as further discussed below, (vii) the accuracy of the representations and warranties made by CME and the Company, respectively, and compliance by CME and the Company with their respective obligations under the Merger Agreement, and (viii) the GFI subsidiaries retained by CME after the IDB Transaction having a specified amount of working capital and available cash on hand following the consummation of the transactions contemplated by the Merger Agreement.

The Combination will qualify as a reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended.

The Merger Agreement contains certain termination rights for both CME and the Company, including if the Combination is not completed on or before March 15, 2015 or if either the JPI Merger Agreement or the IDB Purchase Agreement is terminated in accordance with its terms. In addition, the Merger Agreement provides that, in connection with the termination of the Merger Agreement under specified circumstances, the Company may be required to pay CME a termination fee equal to $20,143,121; and may be required to reimburse CME up to $10 million in expenses in certain instances.

The Merger Agreement contains detailed representations and warranties of the Company, CME, Merger Sub 1 and Merger Sub 2. The Company has agreed to various covenants and agreements, including, among others, an agreement to conduct its business in the ordinary course during the period prior to the closing of the Merger and not to engage in certain kinds of transactions during this period.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached hereto as Exhibit 2.1 and incorporated by reference herein. The Merger Agreement has been included as an exhibit hereto solely to provide investors and security holders with information regarding its terms. It is not intended to be a source of financial, business or operational information about the Company, CME or their respective subsidiaries or affiliates. The representations, warranties and covenants contained in the Merger Agreement are made only for purposes of the Merger Agreement and are made as of specific dates; are solely for the benefit of the parties; may be subject to qualifications and limitations agreed upon by the parties in connection with negotiating the terms of the Merger Agreement, including being qualified by confidential disclosures made for the purpose of allocating contractual risk between the parties rather than establishing matters as facts; and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors or security holders. Investors and security holders should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of the Company, CME or their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures.

Support Agreement

Concurrently with the entry into the Merger Agreement, CME entered into a Support Agreement dated as of the date of the Merger Agreement (the “Support Agreement”) with certain beneficial owners of GFI common stock (the “Stockholders”), including entities controlled by Mr. Gooch. The shares of Genesis common stock subject to the Support Agreement constituted approximately 38% of the total issued and outstanding shares of GFI common stock as of June 30, 2014. On the terms and conditions set forth in the Support Agreement, the Stockholders agreed to vote or cause to be voted their shares in favor of adoption of the Merger Agreement and approval of each of the transactions contemplated thereby. Further, the Stockholders have agreed to vote against (i) the approval of any alternative business combination transaction or (ii) any other action, agreement or transaction that is intended to, or could reasonably be expected to, impede, interfere with, delay, postpone or affect the transactions contemplated by the Merger Agreement. The Support Agreement will terminate upon the earliest to occur of (a) the Effective Time, (b) the termination of the Support Agreement by the mutual written consent of CME and the Stockholders, (c) a termination of the Merger Agreement due to (i) a breach of CME’s representations, warranties or covenants thereto or (ii) because the outside date has been reached or a restraint on the Combination has been imposed, in the case of (ii), solely due to the failure to obtain certain antitrust approvals or (d) 12 months after the termination of the Merger Agreement (such period, the “Tail Period”).

In the event that during the Tail Period, as a result of the financial condition of the Company, there is, or is reasonably likely to be, a default under the Company’s indenture or credit agreement that, if not cured, would result in the relevant GFI obligor party’s obligations to be accelerated, the obligations of the Stockholders under the Support Agreement will terminate solely to the extent necessary to allow the Stockholders to approve the sale of all the equity of the Company or all or substantially all of the assets of the Company to a bona fide third-party purchaser.

The foregoing description of the Support Agreement does not purport to be complete and is qualified in its entirety by reference to the Support Agreement, which is attached hereto as Exhibit 10.1 and incorporated by reference herein.

JPI Merger Agreement

On July 30, 2014, CME, Cheetah Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of CME (“Merger Sub 3”), Cheetah Acquisition LLC, a Delaware limited liability company and a wholly-owned subsidiary of CME (“Merger Sub 4”), Jersey Partners Inc., a New York corporation (“JPI”), New JPI Inc., a Delaware corporation (“New JPI”), and the other individuals signatory thereto, which are stockholders of JPI and New JPI (the “Signing Stockholders”) entered into an Agreement and Plan of Merger (the “JPI Merger Agreement”) providing for the merger of Merger Sub 3 with and into New JPI (the “JPI Merger”), with New JPI continuing as the surviving corporation in the JPI Merger (the “JPI Merger Surviving Corporation”), which will be followed, immediately after the effective time of the JPI Merger (the “JPI Merger Effective Time”), by a merger of the JPI Merger Surviving Corporation with and into Merger Sub 4 (the “Subsequent JPI Merger” and, together with the JPI Merger, the “JPI Combination”), with Merger Sub 4 to be the surviving entity in the Subsequent JPI Merger. As a result of the JPI Mergers, Merger Sub 4 will become a wholly-owned subsidiary of CME.

At the JPI Merger Effective Time, by virtue of the JPI Merger and without any action on the part of the holders of any shares of the capital stock of New JPI, each share of New JPI common stock (“New JPI Common Stock”) issued and outstanding immediately prior to the JPI Merger Effective Time (other than shares of New JPI common stock owned by New JPI) will be converted into the right to receive a fraction of a share of CME Class A Common Stock (the “JPI Exchange Ratio”). The JPI Exchange Ratio is a fraction, the numerator of which equals the aggregate number of shares of CME Class A Common Stock that would be payable if such shares were converted into the merger consideration provided for in the Merger Agreement and the denominator of which equals the maximum number of shares of New JPI Common Stock that could be issued and outstanding immediately prior to the Effective Time.

The consummation of the JPI Combination is subject to customary closing conditions, including, without limitation, (i) the delivery to CME by the Signing Stockholders, in their capacity as stockholders of JPI and New JPI, of an irrevocable action by written consent to adopt the JPI Merger Agreement, (ii) the shares of common stock of CME to be issued in the JPI Merger being approved for listing on NASDAQ, (iii) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and any other waiting periods under certain specified foreign competition laws, receipt of other specified regulatory approvals and the provision of certain notices to third parties, (iv) the absence of any law or order that is in effect and restrains, enjoins or otherwise prohibits the JPI Combination, (v) the completion of a pre-closing reorganization of JPI and New JPI, and the satisfaction or waiver of the conditions to closing of the Merger Agreement and the IDB Purchase Agreement as further discussed above, (vi) the accuracy of the respective representations and warranties made by CME, Merger Sub 3, Merger Sub 4, JPI, New JPI and the Signing Stockholders, and compliance by CME, Merger Sub 3, Merger Sub 4, JPI, New JPI and the Signing Stockholders with their respective obligations under the JPI Merger Agreement, and (vii) not more than five percent (5%) of the holders of the issued and outstanding shares of New JPI Common Stock or JPI Common Stock having demanded and not withdrawn) appraisal of their shares. The JPI Combination will qualify as a reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended.

The JPI Merger Agreement contains certain termination rights for both CME and New JPI, including if the JPI Combination is not completed on or before March 15, 2015 or if either the Merger Agreement or the IDB Purchase Agreement is terminated in accordance with its terms.

The JPI Merger Agreement contains detailed representations and warranties of CME, Merger Sub 3, Merger Sub 4, JPI, New JPI and the Signing Stockholders.
