Exhibit (a)(5)(i) MBIA CAPITAL /CLAYMORE MANAGED DURATION INVESTMENT GRADE MUNICIPAL FUND ANNOUNCES TENDER OFFER PROGRAM NEW YORK, NY- November 27, 2009 - MBIA Capital/Claymore Managed Duration Investment Grade Municipal Fund (the "Fund") (NYSE:MZF) today announced that it will commence a tender offer for up to 15% of its outstanding common shares at a price equal to at least 98% of the Fund's net asset value ("NAV") per share on the date the tender offer expires. The Fund will commence the initial tender offer prior to March 1, 2010 (the "Initial Tender Offer"). In addition, upon the occurrence of certain events as set forth below and certain other terms and conditions, the Fund's Board of Trustees has also agreed to conduct three additional tender offers as soon as reasonably practicable after June 1, 2010, September 1, 2010 and December 1, 2010 (the "Conditional Tender Offers"). The Fund will commence each Conditional Tender Offer for up to 5% of the then outstanding common shares of MZF at a price equal to at least 98% of the NAV of MZF's common shares as determined as of the close of regular trading session of the New York Stock Exchange on the date such Conditional Tender Offer expires, if during approximately three calendar months prior to such Conditional Tender Offer (each a "Conditional Tender Offer Test Period"), the common shares of MZF have traded on the New York Stock Exchange at an average daily discount from NAV of more than 5% during the applicable Conditional Tender Offer Test Period. If the average of MZF's daily discount of market price to net asset value for each trading day in the applicable Conditional Tender Offer Test Period is less than 5% during such period, MZF will not conduct any subsequent Conditional Tender Offers. Each Conditional Tender Offer is also subject to certain additional terms and conditions including, for example, that such Conditional Tender Offer would not constitute a breach of Board of Trustee's fiduciary duty owed to MZF or its shareholders. The Fund believes that conducting the tender offers at a price equal to at least 98% of NAV will accommodate the interests of shareholders who seek an opportunity to dispose of their shares as well as shareholders who desire to remain shareholders of the Fund. The tender offers described in this announcement, including the Initial Tender Offer, have not yet commenced. Each of the tender offers will be made, and the shareholders of the Fund will be notified, in accordance with the Securities Exchange Act of 1934, as amended, the Investment Company Act of 1940, as amended, and other applicable rules and regulations. This announcement is not an offer to purchase or a solicitation of an offer to sell shares of the Fund. The tender offers will be made only by an Offer to Purchase for Cash and the related Letter of Transmittal. As soon as each tender offer commences, the Fund will file a tender offer statement with respect to such tender offer with the Securities and Exchange Commission. Shareholders should read the Offer to Purchase for Cash and the related Letter of Transmittal when it is available because it contains important information.
