2.2 Note to Investors

Investors and prospective investors should note that the Issuers may further revise the Eligible Projects listed in this Supplementary Prospectus and in the Base Prospectus from time to time and the proceeds of issues of Notes may therefore be allocated to Eligible Projects which are not listed in this Supplementary Prospectus or in the Base Prospectus. Furthermore, there is no obligation whatsoever on the Issuers to allocate any proceeds of any issuance of Notes to finance Eligible Projects.

It should also be noted that there is currently no clear definition (legal, regulatory or otherwise) of, nor market consensus as to what constitutes, a "green", "social" or equivalently labelled project or as to what precise attributes are required for a particular project to be defined as "green", "social" or such other equivalent label, nor can any assurance be given that such a clear definition or consensus will develop over time. Accordingly, no assurance is or can be given to investors that any projects or uses the subject of, or related to, any of the businesses and projects funded with the net proceeds of the issuance of the Notes will meet any or all investor expectations regarding such "green", "social" or other equivalently-labelled performance objectives or that any adverse environmental, social and/or other impacts will not occur during the implementation of any projects or uses the subject of, or related to, any of the businesses and projects funded with the net proceeds of the issuance of the Notes.

See further the section of the Base Prospectus entitled "Risk Factors – 3.8 The use of proceeds of the Notes may not meet investor expectations or requirements".
