4. The following section is inserted immediately after the last paragraph on page 34 of the Booklet prior to the paragraphs inserted by the June 2007 Supplement: OPTIONS ON CONVENTIONAL INDEX-LINKED SECURITIES Index-linked securities are debt securities that trade on exchanges similarly to equity securities. Index-linked securities are issued by financial institutions such as banks and may take the form of trust certificates, units or some other interest. An index-linked security provides owners with a cash return based on the performance of a "reference asset" which may, for example. consist of a securities or commodities index, a futures index, a physical commodity, a foreign currency. another debt security, or some combination of the above. References in this booklet to "units" of underlying index-linked securities include these various forms of interests. The term "index" in the context of an index-linked security has a broader meaning than that set forth in Chapter IV because, in the context of an index-linked security, the term is a synonym for the term "reference asset" and is not limited to securities indexes. As of the date of this Supplement, options are approved to be traded on conventional index-linked securities, but not on leveraged or inverse index-linked securities. As a general rule, a single index-linked security option covers 100 units of the underlying security. However. it is possible that the number of underlying units covered by an index-linked security option would be adjusted after the option is issued if an adjustment panel determines, as described below, that it is appropriate to make such an adjustment. The exercise prices of options on index-linked securities that are approved for trading at the date of this booklet are stated in U.S. dollars per unit. As with a stock option, the exercise price of an index-linked security option must be multiplied by the number of units underlying the option in order
