WHEREAS

(A) The Pearson Group Pension Plan (the Plan) (originally known as the Fairey Company Limited Pension and Life Assurance Plan for Hourly Paid Employees) was established by a trust deed dated 30 March 1973 by the Fairey Company Limited for the provision of retirement benefits for and in respect of certain employees and former employees of companies that participate in the Plan.

(B) The Plan is currently administered and governed in accordance with the provisions of the eighth consolidated trust deed (the Trust Deed) dated 8 February 2006, made between the Principal Company and the Trustee (as amended) and the rules adopted in accordance with the Trust Deed for the various sections of the Plan for the time being in force.

(C) The Trustee is the trustee of the Plan and the Principal Company is the current principal company of the Plan.

(D) IDCO UK is currently a participating employer under the Plan. IDCO UK is a subsidiary of Interactive Data Corporation Inc (IDCO Inc). Currently, Xxxxxxx plc (the parent company of the Principal Company) holds 61% of the shares of capital stock of IDCO Inc.

(E) The Principal Company, Xxxxxxx plc, Xxxxxxx DBC Holdings, Inc, Xxxxxxx Management Services Limited, the Trustee, IDCO Inc, IDCO UK, and HG Investors LLC are parties to a pensions transitional agreement dated on or about the date of this Deed (as amended from time to time, the Pensions Transitional Agreement). That agreement has been entered into because, pursuant to the transaction described in the recitals to the Pensions Transitional Agreement, Xxxxxxx plc is to dispose of its shareholding in IDCO Inc with effect from the date of completion of that transaction (the Closing Date).

(F) Pursuant to clause H.7 of the Trust Deed, IDCO UK wishes to give notice in writing to the Trustee that it is terminating its liability to make contributions to the Plan in respect of all its employees with effect on and from the Closing Date.
