(a) the Service Provider, Sub-hubco and the Proposed Substitute shall enter into a novation agreement (the "Novation Agreement") and any other requisite agreements, in form and substance satisfactory to the Service Provider (acting reasonably), pursuant to which:

(ii) the Authority has performed and discharged in full or procured the performance and discharge in full of the obligations of Sub-hubco under the Service Contract in relation to the maintenance of records and the provision of reports during the Step-in Period up to the Novation Effective Date so as to permit the Service Provider to monitor the performance of Sub-hubco's other obligations under the Service Contract.
4.5.4 the Authority and the Service Provider shall use all reasonable endeavours to agree and the Authority shall use reasonable endeavours to procure that the Proposed Substitute agrees any amendments to the Service Contract necessary to reflect Clause 3.2.2 and the fact that the Design Build Finance and Maintain Agreement may have terminated at the time of the Novation Effective Date.
