More than likely you’re already a customer of one or more of these institutions, be it your bank, mortgage lender or insurance company. So why not become an investor as well? Why consider investing in the Financial Institutions Portfolio? Dividend income In addition to the potential for capital appreciation, the trust also seeks to provide an attractive stream of dividend income. Portfolio diversification The portfolio is diversified across a variety of market sectors, including commercial banks, insurance companies, thrifts and mortgage finance companies, investment banking and securities firms and diversified financial services companies. Names you know The portfolio invests in some of the world’s largest and most well-known financial institutions. Professional selection When selecting companies for inclusion in the portfolio Van Kampen considered elements such as geographic location of the institutions, credit trends, interest rates, individual investor activity and the level of premiums in the insurance industry. Depending upon the type of financial institution, both value and growth metrics may be considered.

Please consider the investment objectives, risks, charges and expenses of the unit investment trust carefully before investing. The prospectus contains this and other information about the unit investment trust. To obtain a prospectus, contact your financial advisor or download one at vankampen.com. Please read the prospectus carefully before investing. Risk considerations There is no assurance the trust will achieve its investment objective. An investment in this unit investment trust is subject to market risk, which is the possibility that the market values of securities owned by the trust will decline and that the value of trust units may therefore be less than what you paid for them. This trust is unmanaged and its portfolio is not intended to change during the trust’s life except in limited circumstances. Accordingly, you can lose money investing in this trust. A portfolio concentrated in a single market sector presents more risk than a portfolio broadly diversified over several market sectors. This trust is concentrated in the financial sector. There are certain risks specific to the financial institutions sector such as the potential adverse effects of an economic recession, volatile interest rates and state and federal regulations. Common stocks do not assure dividend payments. Dividends are paid only when declared by an issuer’s board of directors and the amount of any dividend may vary over time.

* The Estimated Net Annual dividend per unit listed on the front page is as of 05/10/10 and is based on the most recently declared quarterly dividends, interim and ﬁnal dividends accounting for any foreign withholding taxes or scheduled income payments, but may also be based upon several recently declared dividends. The actual net annual income distributions you receive will vary from the estimate set forth above with changes in the trust's fees and expenses, in income received, currency ﬂuctuations and with the call, maturity or sale of securities. The actual net annual distributions are expected to decrease over time because a portion of the securities included in the trust will be sold to pay for organization costs, deferred sales charges and the creation and development fee. Securities may also be sold to pay regular fees and expenses during the trust's life. Morningstar Datalab is the source for the style box that appears on the reverse of this page. The Morningstar Equity Style Box™ is based on holdings as of the date of deposit of the trust and may vary thereafter. The Morningstar Equity Style Box™ placement is based on two variables. First, on a trust’s market capitalization relative to the movements of the market and second, the valuation by comparing the stocks in the trust’s portfolio with the most relevant of the three market capitalization groups.
