Either Party (‘the Initiating Party’) may initiate changes to the MSA by submitting a written request to the other Party (‘the Receiving Party’). The Receiving Party will review any change requests and advise the Initiating Party if the request can be accepted and, if so, the changes will be incorporated into this MSA (‘the Amendments’). The Amendments will only be effective when made in writing and signed by both parties. Acceptance of a requested change will not be unreasonably withheld or delayed and each Party nominates the person stated in Item 9 of the Contract Details (‘the Authorised Delegate’), to expeditiously consider requests in relation to all the Schedules of this MSA. Amendments concerning the remainder of this MSA will be subject to the same level of authorisation as the execution of this MSA. Unless otherwise expressly stated in the Amendment, the Amendment will be deemed for billing purposes to be effective from the first day of the next invoice.
