      Claymore Securities, Inc. today announced that it has launched seven new 
      ETFs on the American Stock Exchange (AMEX); expanding its U.S.-listed 
      ETF family to 18 funds. Included in this most recent launch are the

      and the first patent-value growth index ETF:
    
    
      Claymore/BIR Leaders 50 ETF (AMEX:BST)
    
    
      The Fund seeks investment results that correspond generally to the 
      performance, before the Fund’s fees and 
      expenses, of an index called the BIR Leaders 50 Index. The Index is 
      comprised of 50 stocks selected from a universe of common stocks and 
      ADRs listed on U.S. exchanges and covered by Best Independent Research, 
      LLC, a consortium of the following five independent research companies: 
      Ativo Research, Channel Trend Inc., Columbine Capital Services, Ford 
      Equity Research, and Thomas White International.
    
    
      Claymore/Ocean Tomo Growth Index ETF (AMEX:OTR)
    
    
      The Fund seeks investment results that correspond generally to the 
      performance, before the Fund’s fees and 
      expenses, of an equity index called the Ocean Tomo 300® 
      Patent Growth Index. The Index is comprised of 60 stocks selected, based 
      on investment and other criteria, from a universe of U.S. listed 
      companies. The universe of companies includes the 300 companies that 
      comprise the Ocean Tomo 300® 
      Patent Index without limit on market capitalization, but which are 
      primarily mid-to-large capitalization companies with capitalization in 
      excess of $1 billion. The companies in the universe are selected using 
      criteria as identified by Ocean Tomo.
    
    
      Claymore/Zacks Growth & Income Index ETF (AMEX:CZG)
    
    
      The Fund seeks investment results that correspond generally to the 
      performance, before the Fund’s fees and 
      expenses, of an equity index called the Zacks Growth & Income Index. The 
      Index is comprised of 225 stocks selected, based on investment and other 
      criteria, from a universe of the 1,500 most liquid U.S. listed equity 
      securities. The universe of securities includes all U.S. stocks, 
      including ADRs, listed on domestic exchanges. The securities in the 
      universe are selected using a proprietary methodology developed by Zacks 
      Investment Research, Inc. The methodology adjusts over time based on the 
      assets in the portfolio to ensure investability at higher capacity 
      levels.
    
    
      Additionally, Claymore announced the launch of its first four domestic 
      style box ETFs. “Claymore is committed to 
      building a best-in-class family of ETFs designed for advisors and their 
      clients,” stated Christian Magoon, Senior 
      Managing Director of Claymore. “We are excited 
      to partner with these index providers and expand our industry-recognized 
      innovation to traditional, style-based asset allocation.” 
      The new style-box ETFs are:

      expenses, of an index called the BIR Leaders Mid-Cap Value Index. The 
      Index is comprised of approximately 100 stocks selected from a universe 
      of mid-capitalization value common stocks or ADRs listed on U.S. 
      exchanges covered by Best Independent Research, LLC, a consortium of the

      The companies included in the Index universe are selected using a

      cash flow returns relative to a stock’s 
      current multiple as well as comparable common stocks at competitive

      Important Risks and Other Considerations
    
    
      This information does not represent an offer to sell securities of funds 
      and it is not soliciting an offer to buy securities of the funds. There 
      can be no assurance that the funds will achieve their investment 
      objectives. An investment in the various Claymore ETFs is subject to 
      certain risks and other considerations. Such risks and considerations 
      include, but are not limited to:
    
    
      Investment Risk (All): An investment in the funds is subject to 
      investment risk, including the possible loss of the entire principal 
      amount that you invest.
    
    
      Equity Risk (All): The risk that the value of the securities held by the 
      funds will fall due to general market and economic conditions, 
      perceptions regarding the industries in which the issuers of securities 
      held by the Fund participate, or factors relating to specific companies 
      in which the funds invests.
    
    
      Foreign Investment Risk (All): The fund's investments in non-U.S. 
      issuers may involve unique risks compared to investing in securities of 
      U.S. issuers, including, among others, greater market volatility than 
      U.S. securities and less complete financial information than for U.S. 
      issuers. The fund's investments in foreign securities may involve higher 
      costs than investments in U.S. securities, including higher transaction 
      and custody costs as well as the imposition of additional taxes by 
      foreign governments. The fund's foreign investments may also involve 
      risks associated with the level of currency exchange rates, less 
      complete financial information about the issuers, less market liquidity, 
      more market volatility and political instability. Future political and 
      economic developments, the possible imposition of withholding taxes on 
      dividend income, the possible seizure or nationalization of foreign 
      holdings, the possible establishment of exchange controls or freezes on 
      the convertibility of currency, or the adoption of other governmental 
      restrictions might adversely affect the fund's investments in foreign 
      securities. Additionally, foreign issuers may be subject to less 
      stringent regulation, and to different accounting, auditing and 
      recordkeeping requirements. In addition, the underlying issuers of 
      certain depositary receipts, particularly unsponsored or unregistered 
      depositary receipts, are under no obligation to distribute shareholder 
      communications to the holders of such receipts, or to pass through to 
      them any voting rights with respect to the deposited securities.
    
    
      Non-Correlation Risk (All): The fund's return may not match the return 
      of the Index for a number of reasons. For example, the Fund incurs a 
      number of operating expenses not applicable to the Index, and incurs 
      costs in buying and selling securities, especially when rebalancing the 
      fund’s securities holdings to reflect changes 
      in the composition of the Index.
    
    
      Small and Medium-Sized Company Risk (BST, CZG): Investing in securities 
      of small and medium-sized companies involves greater risk than is 
      customarily associated with investing in more established companies. 
      These companies' stocks may be more volatile and less liquid than those 
      of more established companies. These stocks may have returns that vary, 
      sometimes significantly, from the overall stock market.
    
    
      Replication Management Index (All): Unlike many investment companies, 
      the funds are not "actively" managed. Therefore, it would not 
      necessarily sell a stock because the stock's issuer was in financial 
      trouble unless that stock is removed from the Index.
    
    
      Issuer-Specific Changes (All): The value of an individual security or 
      particular type of security can be more volatile than the market as a 
      whole and can perform differently from the value of the market as a 
      whole. The value of securities of smaller issuers can be more volatile 
      than that of larger issuers.
    
    
      Non-Diversified Fund Risk (All):The Fund is considered non-diversified 
      and can invest a greater portion of assets in securities of individual 
      issuers than a diversified fund. As a result, changes in the market 
      value of a single investment could cause greater fluctuations in share 
      price than would occur in a diversified fund.
    
    
      Patent Risk (OTR): The companies in which the Claymore/Ocean Tomo Growth 
      ETF invests (via the Index) can be significantly affected by patent 
      considerations, including the termination of their patent protection for 
      their products.
    
    
      Small Company Risk (BES): Investing in securities of small companies 
      involves greater risk than is customarily associated with investing in 
      more established companies. These companies’ 
      stocks may be more volatile and less liquid than those of more 
      established companies. These stocks may have returns that vary, 
      sometimes significantly, from the overall stock market.
    
    
      Medium Sized Company Risk (BMV, OTR, CZA): Investing in securities of 
      medium sized companies involves greater risk than is customarily 
      associated with investing in more established companies. These companies’ 
      stocks may be more volatile and less liquid than those of more 
      established companies. These stocks may have returns that vary, 
      sometimes significantly, from the overall stock market.

      broker-dealers or large institutional investors with creation and 
      redemption agreements, called authorized participants (“APs”), 
      can purchase or redeem these Creation Units.
