shall not, during and in respect of the period from the date of this Agreement
to the Closing Date alter the Trust Deed or Rules or exercise any other power or

(a)

with the written consent of IDCO UK (such consent not to be unreasonably withheld or delayed (it being acknowledged that it will not be deemed unreasonable for IDCO UK to withhold or delay consent if any action or omission to act by Pearson and/or the Trustee results in any change to the obligations of IDCO UK under the Schedule of Contributions dated 22 March 2010 or in any other material increases to IDCO UK153s obligations)); or

(c)

if such actions are being taken in the normal course of administering the PGPP and/or affect all participating employers in the PGPP in the same manner (including, for the avoidance of doubt, (i) the revision of actuarial factors used in the calculation of early retirement and late retirement benefits, and conversion of a member153s voluntary contributions to benefits under the PGPP, and (ii) the replacement of the Trust Deed and Rules with documents that have been rewritten for the purpose of facilitating ease of administration and updating legislative references; both of which (i) and (ii) are expected to occur between the date of this Agreement and the Closing Date).

Obligations of IDCO

2.4 IDCO UK agrees that it will (and IDCO shall procure that IDCO UK will),

(a)	comply in all material respects with the provisions of the PGPP and the obligations imposed on an employer in relation to the PGPP by relevant legislation;

(d)	not do or omit to do anything whereby the position of the PGPP as a registered pension scheme or as a contracted out scheme would or might be prejudiced.

2.5 The parties to this Agreement acknowledge that the Pensions Act 1995 and

(c)

Pearson Services may exercise the authorities and discretions envisaged by this clause in its absolute unfettered discretion and in its own interests. Save as provided in this Agreement (and in particular, without limitation, clause 2.2 when read in conjunction with clause 2.3), the Purchaser and IDCO accept that Pearson Services owes no duty or responsibility to IDCO UK, to the Purchaser, or to IDCO Inc in relation to the exercise of the authorities and discretions envisaged as conferred on Pearson Services by this clause.

relating to consultation of the IDCO UK employees (whether under The
