12.1 The respective Participants' Representatives shall be
[insert name of each Participant's Representative and Participant in respect of which they are to act]
or such other persons appointed by each Participant from time to time pursuant to this clause. Each Participant's Representative shall exercise the functions and powers of that Participant in relation to the operation of this Agreement and the hubco Operations which are identified in this Agreement as functions or powers to be carried out by the Participant's Representative. Each Participant's Representative shall also exercise such other functions and powers of that Participant under this Agreement as that Participant may notify to hubco in writing from time to time. Each Participant's Representative shall represent that Participant only and shall have no power to delay anything in relation to or exercise the functions or powers of any other Participant.
12.2 Each Participant's Representative shall be entitled at any time, by written notice to hubco, to authorise any other person to exercise the functions and powers of that Participant delegated to him pursuant to this clause as set out in such notice, either generally or specifically. Any act of any such person shall, for the purposes of this Agreement, constitute an act of that Participant's Representative and all references to the Participant's Representative in this Agreement (apart from this Clause 12.2) shall be taken as references to such person so far as they concern matters within the scope of such person's authority (as so notified in writing to hubco).
12.3 Each Participant may by written notice to hubco and the other Participants change the identity of their Participant's Representative. Each Participant shall (as far as practicable) consult with hubco and the other Participants prior to the appointment of any replacement for its Participant's Representative, taking account of the need for liaison and continuity in respect of this Agreement. Such change shall have effect on the date specified in the written notice (which date shall, other than in the case of emergency, be such date as will not cause material inconvenience to hubco in the execution of its obligations under this Agreement).
12.4 During any period when no Participant's Representative has been appointed in relation to one or more Participants (or when a Participant's Representative is unable through illness, incapacity or any other reason whatsoever to carry out or exercise his functions under this Agreement) the affected Participant shall carry out the functions which would otherwise be performed by that Participant's Representative.
12.5 No act or omission of a Participant's Representative or any officer, employee or other person engaged by a Participant shall, except as otherwise expressly provided in this Agreement:
12.5.1 in any way relieve or absolve hubco from, modify, or act as a waiver of or personal bar against claiming in respect of, any liability, responsibility, obligation or duty of hubco arising out of this Agreement; or
12.5.2 in the absence of an express order or authorisation under this Agreement constitute or authorise a variation hereto.
12.6 Except as previously notified in writing before such act by a Participant to hubco, hubco and hubco's Representative shall be entitled to treat any act of that Participant's Representative which is authorised by this Agreement as being expressly authorised by that Participant and hubco and hubco's Representative shall not be required to determine whether an express authority has in fact been given.
