 It is not possible to forecast the impact, if any, that any such discontinuance may have on the
market for the Notes. Although other broker-dealers may make a market in the Notes from time to time, there can be no assurance that any other broker-dealer will do so at any time when HSI discontinues its market- making activities. In addition, any
such broker-dealer that is engaged in market-making activities may thereafter discontinue such activities at any time at its sole discretion.

We do not expect to receive any proceeds from market-making transactions.

Information about the trade and settlement dates, as well as the purchase price, for a market-making transaction will be provided to the
purchaser in a separate confirmation of sale.

In connection with any use of this prospectus supplement and the accompanying prospectus by
HSI or another of our affiliates, you may assume this prospectus supplement and the accompanying prospectus is being used in a market-making transaction unless otherwise specified.
