PROSPECTIVE INVESTORS ASSOCIATED WITH THE ISSUER OR A CMI (INCLUDING ANY OF ITS GROUP COMPANIES) SHOULD SPECIFICALLY DISCLOSE WHETHER THEY HAVE ANY SUCH ASSOCIATION TO A CMI AND THE JOINT LEAD MANAGERS (AND SUCH CMI AND THE JOINT LEAD MANAGERS MAY BE REQUIRED TO PASS SUCH INFORMATION TO THE ISSUER AND CERTAIN OTHER CMIS) WHEN PLACING AN ORDER FOR THE NOTES AND SHOULD DISCLOSE, AT THE SAME TIME, IF SUCH ORDERS MAY NEGATIVELY IMPACT THE PRICE DISCOVERY PROCESS IN RELATION TO THE OFFERING. PROSPECTIVE INVESTORS WHO DO NOT DISCLOSE THEIR ASSOCIATIONS ARE DEEMED NOT TO BE SO ASSOCIATED. WHERE PROSPECTIVE INVESTORS DISCLOSE SUCH ASSOCIATIONS BUT DO NOT DISCLOSE THAT SUCH ORDER MAY NEGATIVELY IMPACT THE PRICE DISCOVERY PROCESS IN RELATION TO THE OFFERING, SUCH ORDER IS HEREBY DEEMED NOT TO NEGATIVELY IMPACT THE PRICE DISCOVERY PROCESS IN RELATION TO THE OFFERING. IF A PROSPECTIVE INVESTOR IS AN ASSET MANAGEMENT ARM AFFILIATED WITH A CMI, SUCH PROSPECTIVE INVESTOR SHOULD INDICATE WHEN PLACING AN ORDER IF IT IS FOR A FUND OR PORTFOLIO WHERE SUCH CMI OR ITS GROUP COMPANY HAS MORE THAN 50% INTEREST, IN WHICH CASE IT WILL BE CLASSIFIED AS A “PROPRIETARY ORDER” AND SUBJECT TO APPROPRIATE HANDLING BY CMIS IN ACCORDANCE WITH THE SFC CODE AND SHOULD DISCLOSE, AT THE SAME TIME, IF SUCH “PROPRIETARY ORDER” MAY NEGATIVELY IMPACT THE PRICE DISCOVERY PROCESS IN RELATION TO THE OFFERING.

PRIVATE BANKS WHO DO NOT PROVIDE SUCH DISCLOSURE ARE HEREBY DEEMED TO BE PLACING THEIR ORDER ON SUCH A “PRINCIPAL” BASIS. OTHERWISE, SUCH ORDER MAY BE CONSIDERED TO BE AN OMNIBUS ORDER (SEE FURTHER BELOW) PURSUANT TO THE SFC CODE.

IN THE CASE OF OMNIBUS ORDERS PLACED WITH THE JOINT LEAD MANAGERS, CMIS (INCLUDING PRIVATE BANKS) SHOULD, AT THE SAME TIME, DISCLOSE UNDERLYING INVESTOR INFORMATION (NAME, UNIQUE IDENTIFICATION NUMBER, WHETHER THE UNDERLYING INVESTOR HAS ANY ASSOCIATIONS AND WHETHER ANY UNDERLYING INVESTOR ORDER IS A “PROPRIETARY ORDER” AND/OR A DUPLICATE ORDER) IN THE FORMAT AND TO THE RELEVANT RECIPIENTS INDICATED TO SUCH CMIS (INCLUDING PRIVATE BANKS) BY THE JOINT LEAD MANAGERS AT THE RELEVANT TIME.
