in Clause 4 (LIFFE Payment Undertaking) will only take effect on the fulfilment at all times of the conditions set out in Clause 3.3 and is conditional upon such conditions being fulfilled to the reasonable satisfaction of the relevant Party
or Parties (or waived by written agreement of such Party or Parties) by 30 September 2009 (or such later date as the Parties may agree in writing) (the Longstop Date).

and shared it with LIFFE; and
| | ----- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3.3.2 | the execution of, and the fulfilment (or waiver, as the case may be) of the conditions set out in Clause 3.3 of, the Clearing Relationship Agreement, but for the requirement to
fulfil or waive the conditions precedent set out in this Agreement, and the commencement of the LCH Services.
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3.4 | This Agreement shall terminate if the conditions above are not satisfied by the Longstop Date. However, termination does not affect a Partys accrued rights and obligations

|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Such sum shall be paid by way of compensation for economic losses arising as a result of termination of
the Current Clearing Terms on the Commencement Date. The Parties further agree that the Settlement Sum does not represent consideration in respect of any goods or services supplied or to be supplied by LCH to LIFFE.

---

| | from HM Revenue & Customs to this effect. However, in the event that HM Revenue & Customs issue a final ruling that VAT is chargeable on
the Settlement Sum the parties will work together and use their best endeavours to secure a mutually acceptable outcome.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5.3 | If, notwithstanding Clause 5.2 above, VAT is or becomes chargeable on the Settlement Sum then it is agreed that LIFFE shall pay an additional amount equal to such VAT to LCH on
receipt of a valid VAT invoice. LIFFE shall also be liable for any interest or penalties payable by LCH to HM Revenue & Customs as a result of the late payment of any VAT chargeable on the Settlement Sum.
