A.  To revise the “Underwriting Discount” and “Proceeds to CIBC” columns and footnote (2) on the cover page of the Pricing Supplement as follows:

(2) The total “Underwriting Discount” and “Proceeds to CIBC” to be specified above will reflect the aggregate of the underwriting discounts per Note at the time CIBC established any hedge positions prior to the Trade Date, which may be variable and fluctuate depending on market conditions at such times, but in any event will not exceed 5.00%, or $50.00 per $1,000 principal amount of Notes. Jefferies LLC may use a portion of its commission to allow selling concessions to other dealers in connection with the distribution of the Notes. The other dealers may forgo, in their sole discretion, some or all of their selling concessions. See “Supplemental Plan of Distribution” on page PRS-40 of this pricing supplement; and

B.         To revise the fifth sentence of the second paragraph of “Supplemental Plan of Distribution” on page PRS-40 as follows:

Jefferies may receive a commission of up to $50.00 (5.00%) per $1,000 principal amount of the Notes and may use a portion of that commission to allow selling concessions to other dealers in connection with the distribution of the Notes.
