Risks Relating to the Bonds

You may be unable to sell your bonds if a trading market for the bonds does not develop.

The bonds will be new securities for which there is currently no established trading market, and none may develop. We do not intend to apply
for listing of the bonds on any securities exchange or for quotation on any automated dealer quotation system. The liquidity of any market for the bonds will depend on the number of holders of the bonds, the interest of securities dealers in making
a market in the bonds, and other factors. Accordingly, we cannot assure you as to the development or liquidity of any market for the bonds. If an active trading market does not develop, the market price and liquidity of the bonds may be adversely
affected. If the bonds are traded, they may trade at a discount from their initial offering price depending upon prevailing interest rates, the market for similar securities, general economic conditions, our performance and business prospects, and
certain other factors.

You might not be able to fully realize the value of the liens securing the bonds.

The security for the benefit of the holders of the bonds can be released without their consent.
