U.S. FEDERAL INCOME TAX CONSIDERATIONS

The discussion entitled “Certain United States Federal Income Tax Consequences” in the accompanying prospectus supplement provides a general summary of certain U.S. federal income tax consequences relating to an investment in the Notes, which you should carefully review prior to investing in the Notes.

You should consult your tax advisor concerning the U.S. federal income tax and other tax consequences of your investment in the Notes in your particular circumstances, including the application of state, local or other tax laws and the possible effects of changes in federal or other tax laws.

SUPPLEMENTAL PLAN OF DISTRIBUTION (CONFLICTS OF INTEREST)

USBI will purchase the Notes from us at the price to public less the selling commissions set forth on the cover page of this pricing supplement for distribution to other registered broker-dealers or will offer the Notes directly to investors. USBI or other registered broker-dealers will offer the Notes at the price to public set forth on the cover page of this pricing supplement. USBI may pay some or all of the selling commissions it receives from us to other affiliated or unaffiliated dealers. These selling commissions will vary and will be up to $40.00 per $1,000 principal amount Note.

With respect to Notes sold to eligible institutional investors or fee-based advisory accounts for which an affiliated or unaffiliated broker-dealer is an investment adviser, the price to the public will be between $960.00 and $1,000 per $1,000 principal amount Note. Broker-dealers who purchase the Notes for these accounts may forgo some or all selling commissions related to these sales.

We expect to deliver the Notes against payment therefor in New York, New York on a date that is more than one business day following the Pricing Date. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to the business day before delivery will be required to specify alternative settlement arrangements to prevent a failed settlement.

Conflicts of Interest

Our affiliate, USBI, is a member of FINRA and is participating in the distribution of the Notes. Because USBI has a conflict of interest pursuant to FINRA Rule 5121, the distribution arrangements for this offering must comply with the requirements of FINRA Rule 5121, regarding a FINRA member firm’s participation in the distribution of securities of an affiliate. In accordance with FINRA Rule 5121, no FINRA member firm that has a conflict of interest under FINRA Rule 5121 may make sales in this offering to any discretionary account without the prior approval of the customer.

Market-Making Resales by Affiliates

Our affiliates, including USBI, may use this pricing supplement, the accompanying prospectus supplement and the prospectus, together with any other applicable prospectus, in connection with offers and sales of Notes in the secondary market. These affiliates may act as principal or agent in those transactions. Secondary market sales will be made at prices related to market prices at the time of sale. In this pricing supplement, the accompanying prospectus supplement and the prospectus, an offering of Notes refers to the initial offering of the Notes made in connection with their original issuance, and does not refer to any subsequent resales of Notes in market-making transactions.

While USBI may make markets in the Notes, it is under no obligation to do so and may discontinue any market-making activities at any time without notice. See the section titled “Plan of Distribution (Conflicts of Interest)” in the accompanying prospectus supplement.

The price at which you purchase the Notes includes costs that we or our affiliates expect to incur and profits that we or our affiliates expect to realize in connection with hedging activities related to the Notes. These costs and profits will likely reduce the secondary market price, if any secondary market develops, for the Notes. As a result, you may experience an immediate and substantial decline in the market value of your Notes on the Original Issue Date.

LEGAL MATTERS

The validity of the Notes will be passed on for us by Willkie Farr & Gallagher LLP, Chicago, Illinois.
