Overview of Key Benefits and

Risks of Investments

Benefits

n Investors can access investments linked to a variety of underlying assets or indices, such as domestic and foreign indices, exchange-traded funds, commodities, foreign-exchange, interest rates, equities, or a combination thereof.

n Structured investments can offer unique risk/ return profiles to match investment objectives, such as the amount of principal due at maturity, periodic income, and enhanced returns.

Risks

n The risks below are not intended to be an exhaustive list of the risks associated with a particular CitiFirst Structured Investment offering. Before you invest in any CitiFirst Structured Investment you should thoroughly review the particular investment’s offering document(s) and related material(s) for a comprehensive description of the risks and considerations associated with the particular investment.

n Potential for Loss

n   The terms of certain investments provide that the full principal amount is due at maturity, subject to the applicable issuer or guarantor credit risk. However, if an investor sells or redeems such investment prior to maturity, the investor may receive an amount less than his/her original investment.

n  The terms of certain investments provide that the payment due at maturity could be significantly less than the full principal amount and, for certain investments, could be zero. In these cases, an investor may receive an amount significantly less than his/ her original investment and may receive nothing at maturity of the investment.

n Appreciation May Be Limited – Depending on the investment, an investor’s appreciation may be limited by a maximum amount payable or by the extent to which the return reflects the performance of the underlying asset or index.

n Issuer or Guarantor Credit Risk – All payments on CitiFirst Structured Investments are dependent on the applicable issuer’s or guarantor’s ability to pay all amounts due on

these investments including any principal due at maturity and therefore investors are subject to the credit risk of the applicable issuer or guarantor.

n Secondary Market – There may be little or no secondary market for a particular investment. If the applicable offering document(s) so specifies, the issuer may apply to list an investment on a securities exchange, but it is not possible to predict whether any investment will meet the listing requirements of that particular exchange, or if listed, whether any secondary market will exist.

n Resale Value of a CitiFirst Structured Investment May be Lower than Your Initial Investment – Due to, among other things, the changes in the price of and dividend yield on the underlying asset, interest rates, the earnings performance of the issuer of the underlying asset, the applicable issuer or guarantor of the CitiFirst Structured Investment’s perceived creditworthiness, the investment may trade, if at all, at prices below its initial issue price and an investor could receive substantially less than the amount of his/her original investment upon any resale of the investment.

n Volatility of the Underlying Asset or Index – Depending on the investment, the amount you receive at maturity could depend on the price or value of the underlying asset or index during the term of the trade as well as where the price or value of the underlying asset or index is at maturity; thus, the volatility of the underlying asset or index, which is the term used to describe the size and frequency of market fluctuations in the price or value of the underlying asset or index, may result in an investor receiving an amount less than he/she would otherwise receive.

n Potential for Lower Comparable Yield – The effective yield on any investment may be less than that which would be payable on a conventional fixed-rate debt security of the same issuer with comparable maturity.

n Affiliate Research Reports and Commentary – Affiliates of the particular issuer may publish research reports or otherwise express opinions or provide recommendations from time to time regarding the underlying asset or index which may influence the price or value of the underlying asset or index and, therefore, the value of the investment. Further, any

research, opinion or recommendation expressed within such research reports may not be consistent with purchasing, holding or selling the investment.

n The United States Federal Income Tax Consequences of Structured Investments are Uncertain – No statutory, judicial or administrative authority directly addresses the characterization of structured investments for U.S. federal income tax purposes. The tax treatment of a structured investment may be very different than that of its underlying asset. As a result, significant aspects of the U.S. federal income tax consequences and treatment of an investment are not certain. The offering document(s) for each structured investment contains tax conclusions and discussions about the expected U.S. federal income tax consequences and treatment of the related structured investment. However, no ruling is being requested from the Internal Revenue Service with respect to any structured investment and no assurance can be given that the Internal Revenue Service will agree with the tax conclusions and treatment expressed within the offering document(s) of a particular structured investment. Citigroup Global Markets Inc., its affiliates, and employees do not provide tax or legal advice. Investors should consult with their own professional advisor(s) on such matters before investing in any structured investment.

n Fees and Conflicts – The issuer of a structured investment and its affiliates may play a variety of roles in connection with the investment, including acting as calculation agent and hedging the issuer’s obligations under the investment. In performing these duties, the economic interests of the affiliates of the issuer may be adverse to the interests of the investor.

Additional Considerations

Please note that the information contained in this brochure is current as of the date indicated and is not intended to be a complete description of the terms, risks and benefits associated with any particular structured investment. Therefore, all of the information set forth herein is qualified in its entirety by the more detailed information provided in the offering documents(s) and related material for the respective structured investment.

The structured investments discussed within this brochure are not suitable for all investors. Prospective investors should evaluate their financial objectives and tolerance for risk prior to investing in any structured investment.

Tax Disclosure

Citigroup Global Markets Inc., its affiliates and employees do not provide tax or legal advice. To the extent that this brochure or any offering document(s) concerns tax matters, it is not intended to be used and cannot be used by a taxpayer for the purpose of avoiding penalties that may be imposed by law. Any such taxpayer should seek advice based on the taxpayer’s particular circumstances from an independent tax advisor.

ERISA and IRA Purchase Considerations

Employee benefit plans subject to ERISA, entities the assets of which are deemed to constitute the assets of such plans, governmental or other plans subject to laws substantially similar to ERISA and retirement accounts (including Keogh, SEP and SIMPLE plans, individual retirement accounts and individual retirement annuities) are permitted to purchase structured investments as long as either (A) (1) no Citigroup Global Markets affiliate or employee is a fiduciary to such plan or retirement account that has or exercises any discretionary authority or control with respect to the assets of such plan or retirement account used to purchase the structured investments or renders investment advice with respect to those assets, and (2) such plan or retirement account is paying no more than adequate consideration for the structured investments or (B) its acquisition and holding of the structured in is not prohibited by any such provisions or laws or is exempt from any such prohibition.

However, individual retirement accounts, individual retirement annuities and Keogh plans, as well as employee benefit plans that permit participants to direct the investment of their accounts, will not be permitted to purchase or hold the structured investments if the account, plan or annuity is for the benefit of an employee of Citigroup Global Markets or Morgan Stanley Smith Barney or a family

member and the employee receives any compensation (such as, for example, an addition to bonus) based on the purchase of structured investments by the account, plan or annuity. You should refer to the section “ERISA Matters” in the applicable offering document(s) for more information.
