|Acceptance:         |  | Licensor shall deliver a production-ready version of the Licensed Product to Licensee by the delivery date set forth in the NextGen DLA (the Delivery Date). The Parties
represent that they shall work together in good faith to establish a reasonable, mutually acceptable Delivery Date. Within [***] of the Delivery Date, Licensee shall commence conducting acceptance testing (the Acceptance Testing Start
Date). (Acceptance testing shall be defined in the NextGen DLA.) Within [***] of the Acceptance Testing Start Date, Licensee shall finish conducting acceptance testing (the Acceptance Testing Finish Date).
Within 5 days of the Acceptance Testing Finish Date, Licensee shall notify Licensor whether the Licensed Product passed or failed acceptance testing. If the Licensed Product fails acceptance testing, Licensee shall specify, in writing, the basis for
such failure. Licensor shall have a period to cure such failure, through modifying the Licensed Product and re-delivering it to Licensee within [***] of Licensees notification. The redelivery of Licensed Product shall constitute a second
Delivery Date, and the Parties shall follow the same time-frame set forth above regarding acceptance testing, however they shall use reasonable efforts to reduce the duration of such periods, if possible. If Licensee fails to commence
conducting acceptance testing by the Acceptance Testing Start Date, the Licensed Product shall be deemed to have passed acceptance

discovers any faults during QA testing, Licensor shall, in good faith and as soon as practical, remedy such fault. Within [***] of the date that the Licensed Product passes acceptance testing, Licensee shall finish conducting QA testing and shall
place the Licensed Product into a production environment. The Licensed Product shall be automatically accepted by Licensee upon completion of [***] of Licensees use of the Licensed Product in a production environment without any level A

Licensor, then Licensee shall have the right to terminate the Agreement, the NextGen DLA, and the NextGen SA and [***] paid by Licensee to Licensor in connection with the Licensed Product, including, but not limited to, the License Fee. The right to
terminate the Agreement, the NextGen DLA, and the NextGen SA and [***] shall be Licensees sole and exclusive remedy if the Licensed Product is not accepted by Licensee by the Final Acceptance Date.

The initial term of the NextGen Exclusivity shall commence on [***] (as defined below) of this Agreement and shall continue until the [***], or Licensee has terminated or opted-out of this Agreement (the Initial Term). Thereafter,
the NextGen Exclusivity shall automatically renew, for successive [***] periods (each, a Renewal Term), until terminated by Licensee at any time upon written notice to Licensor. Upon such termination, Licensor shall immediately
repay any unused portion of any advance payment of the NextGen Exclusivity Fee (as defined below), on a pro rata basis. In the event that Licensee elects (i) not to renew the NextGen Exclusivity [***] or (ii) to terminate or opt-out of
this Agreement, the right to purchase NextGen Exclusivity shall terminate, and shall not be available to Licensee without a separate written agreement between the Parties. In exchange for NextGen Exclusivity, Licensee shall pay Licensor $[***], in
advance, commencing on the first day of the first Renewal Term (the NextGen Exclusivity Fee). For the avoidance of doubt, there shall be no NextGen Exclusivity Fee due and owing for the Initial Term.

| |  | The NextGen Exclusivity shall prohibit Licensor and its Affiliates from [***] (except as set forth below), or otherwise providing any [***] whatsoever with respect to (collectively, the
Prohibited Actions), any [***] of or for any third-party that operates (or is intended to operate) a marketplace for the trading of equity options or equity index options inside the United States. For the avoidance of doubt, the
NextGen Exclusivity shall not prohibit Licensor from licensing any [***] to any third-party to enable such third-party to design, develop, or support any [***] for the purpose of operating a marketplace for the trading of equity options or equity
index options inside the United States, provided that neither Licensor nor any of its Affiliates performs any Prohibited Actions with respect to such [***]. The NextGen Exclusivity shall not prohibit Licensor from providing support services to any
NextGen licensee; provided, however, if Licensor provides support services to a NextGen licensee that operates a marketplace for the trading of equity options or equity index options inside the United Sates, then Licensor shall not be permitted to
rectify any errors or other malfunctions relating to the functionality or operability of such customers [***] for equity options or equity index options.

Effective Date of this Agreement. The NextGen DLA and NextGen SA shall incorporate all of the provisions agreed to in this Agreement, and shall replace this Agreement in its entirety. Each Party shall use its best efforts to execute the NextGen DLA
and NextGen SA within one year following the Effective Date of this Agreement. The NextGen SA shall have effect from the date the Licensed Product passes acceptance testing. Except where Licensee terminates this Agreement pursuant to the termination
section or opt-out section below, Licensee shall immediately pay to Licensor all unpaid portions of the 6 MUSD unadjusted Licensee Fee if the Parties fail to execute the NextGen DLA and the NextGen SA within [***] of the Effective Date of this
Agreement, unless the cause of such failure was solely attributable to the bad faith of Licensor.
|                             | 
|Termination:                 |  | Licensee shall have the right to terminate this Agreement, the NextGen DLA, and the NextGen SA if, prior to acceptance: (i) there is any fundamental change to the Licensed

|               |  | Product (as the Licensed Product is described herein and in the white paper provided to the Licensee dated 10 November 2005 entitled NextGen Custom Extensions: Applied for the
International Securities Exchange, version 0.6), such as, for example, a change to concept of the Licensed Product consisting of the three, separate logical layers; (ii) Licensor determines to cease the commercial development of the Licensed
Product, or Licensor ceases making any material progress towards the commercial development of the Licensed Product; or (iii) Licensor commits a material breach of any provision of the Agreement, the NextGen DLA, or the NextGen SA and fails to cure
such breach within a reasonable time after receiving written notice of such breach. In the context of provision (i), above, it should be recognized by the Parties that the white paper chapters concerning suggested implementation procedures and
division of operational responsibility between the Licensee and Licensor have not been discussed in detail between the Parties. For the avoidance of doubt, changes to such procedures and division of responsibility do not constitute fundamental
changes to the Licensed Product. If Licensee terminates this Agreement, the NextGen DLA and/or the NextGen SA pursuant to this paragraph, then Licensor shall pay to Licensee, without interest, as liquidated damages and not as a penalty, an amount
equal to the sum of any and all amounts paid by Licensee to Licensor in connection with the Licensed Product, including, but not limited to, the License Fee. In fixing this formula for liquidated damages, the Parties acknowledge that it is
difficult, if not impossible, to fix actual damages. Nevertheless, the Parties agree that such formula is fair and reasonable under the circumstances as a method of partially compensating Licensee for the damage it shall suffer as a result of such
termination.
|               | 
|Opt-Out:       |  | Licensee shall have the right to opt-out of (or terminate) this Agreement, the NextGen DLA, and the NextGen SA, if Licensee (i) undergoes a merger or acquisition on or before
[***], and (ii) notifies Licensor, in writing, that it is opting-out of this Agreement pursuant to such merger or acquisition on or before [***]. For purposes of this Agreement, a merger or acquisition shall mean Licensee enters into a
definitive agreement pursuant to which: (1) Licensee acquires, is acquired by or merges with, another entity that operates a securities exchange or commodities exchange, or (2) any other person or entity acquires at least 50.1% of the class A common
stock of Licensee. In the event Licensee opts-out of this Agreement, then Licensor shall retain all License Fee monthly installments previously paid by Licensee, and Licensee shall, within [***] of such opt-out, pay Licensor an opt-out penalty fee,
the amount of which represents [***]% of the present value of the remaining License Fee monthly installments that would have been paid by Licensee (assuming an unadjusted total License Fee of 6 MUSD), subject to a [***]% discount factor, as set
forth in Schedule 3 of this Agreement. For example, if Licensee opts-out in month 6, the amount of the opt-out penalty shall be [***], such that the total amount paid by Licensee to Licensor shall be [***] (the sum of Licensee Fee monthly payments
previously paid and the opt-out penalty amount).                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
|               | 
|Link Software: |  | Licensee undertakes to license link software from Licensor no later than [***]. The world-wide, one time license fee for the link software is USD [***] for unlimited usage, and the costs for
development of, and modifications to, link software, including project costs, amount to at least USD [***], of which Licensee is responsible for at least USD [***]. (No license fee of USD [***] shall be required for a link to the [***] and/or
[***].) If, however, Licensee determines that the appropriate business conditions to commence implementation of the first such link do not occur by [***], Licensee shall have the right to apply the amounts undertaken by Licensee to Licensor for any
incremental services (including, but not limited to, outsourcing services, market data-related services, or, as of the date of this Agreement, incremental CLICK enhancement or support fees) towards the [***] committed amount dollar-for-dollar. The
obligation to license link software shall survive any termination or opt-out of this Agreement by Licensee.

|Non-Disclosure: |  | The Parties agree that they shall keep secret and confidential all proprietary and confidential information including the existence, contents of and any matters arising from this Agreement, and
will neither disclose it to third parties without the prior written consent of the disclosing party, nor use it for any purpose other than that for which it is communicated in connection with the NextGen DLA and NextGen SA. No announcement,
advertisement, circular or other publication concerning or relating to this Agreement or Licensees selection of NextGen (collectively, an Announcement) shall be made (save as required by law or regulation) without the written
consent of both Parties; provided, however, that Licensee, being a highly-visible Licensor customer, has agreed to serve as a reference Licensor customer and announce its intention to migrate to NextGen when Licensor believes appropriate. In the
event of any Announcement required by law or regulation, the Party required to make such Announcement will, so far as practicable, provide the other Party with prior notification of the Announcement and an opportunity to comment.

|                | 
|                |  | Each Party represents and warrants that (i) it has full corporate power and authority to enter into this Agreement (subject, in the case of Licensee, to obtaining approval of this Agreement by
its Board of Directors on or before 30 September 2006), and (ii) its performance does not violate any laws, regulations or agreements applicable to it.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
|                | 
|                |  | On the Effective Date, this Agreement shall become a binding commitment between the Parties on the terms and conditions described herein. The Effective Date (Effective Date)
of this Agreement shall be the date on which this Agreement is approved by the Board of Directors of Licensee. For avoidance of doubt, if the Board of Directors of Licensee does not approve this Agreement on or before 30 September 2006, this
Agreement shall be of no force and effect.
