Item 4.

Purpose of Transaction.

The Reporting Persons purchased the Shares based on the Reporting Persons’ belief that the Shares, when purchased, were significantly undervalued and represented an attractive investment opportunity. Depending upon overall market conditions, other investment opportunities available to the Reporting Persons, and the availability of Shares at prices that would make the purchase of additional Shares desirable, the Reporting Persons may endeavor to increase their position in the Issuer through, among other things, the purchase of Shares on the open market or in private transactions or otherwise, on such terms and at such times as the Reporting Persons may deem advisable.

CUSIP NO. 670655109

No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth in this Schedule 13D or such as would occur upon completion of any of the actions discussed herein. The Reporting Persons intend to review their investment in the Issuer on a continuing basis and engage in discussions with management, the Board of the Issuer and other shareholders of the Issuer concerning the business, operations and future plans of the Issuer. The Reporting Persons are concerned by the persistent discount to net asset value at which the Shares have been trading and believe that the Issuer should take appropriate action to cause the discount to net asset value to be eliminated or reduced. Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels and/or discount to net asset value of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, seeking Board representation, commencing a tender offer, making additional shareholder proposals concerning, among other things, changes to the capitalization, ownership structure or operations of the Issuer or replacement of the Issuer’s investment manager with an investment manager that is concerned with the discount to net asset value at which the Shares have been trading and that will take action to eliminate or reduce such discount, purchasing additional Shares, opposing any transaction resulting in a change of control of the Issuer’s investment manager unless the persistent and excessive discount to net asset value at which the Shares continue to trade is addressed, selling some or all of their Shares, engaging in short selling of or any hedging or similar transaction with respect to the Shares or changing their intention with respect to any and all matters referred to in Item 4.

On July 29, 2009, WITRL filed a complaint (the “Complaint”) in the United States District Court for the District of Massachusetts against the Trustees of the Issuer, Nuveen Florida Investment Quality Municipal Fund, Nuveen Florida Quality Income Municipal Fund and Nuveen Insured Florida Premium Income Municipal Fund (collectively, the “Florida Funds”). The Complaint seeks damages on behalf of classes of shareholders of the Florida Funds as of January 20, 2009 arising from alleged breaches of fiduciary duties by the Trustees of the Florida Funds in connection with the proposed merger of the Florida Funds with and into other funds sponsored by Nuveen Investments, Inc.

WILLC is seeking representation on the Issuer’s Board of Trustees (the “Board”). WILLC delivered a letter dated August 13, 2009 to the Corporate Secretary of the Issuer (the “Nomination Letter”) nominating Arthur D. Lipson and Robert H. Daniels to be elected to the Board at the 2009 annual meeting of shareholders of the Issuer, or any other meeting of shareholders held in lieu thereof, and any adjournments, postponements, reschedulings or continuations thereof (the “2009 Annual Meeting”).

WILLC also delivered a letter to the Corporate Secretary of the Issuer submitting, pursuant to Rule 14a-8 of the Securities Exchange Act of 1934, as amended, a proposal for inclusion in the Issuer’s proxy for the 2009 Annual Meeting and to be voted on at the 2009 Annual Meeting (the “14a-8 Proposal”). WILLC is proposing that the Board take all necessary steps to ensure that in the case of a merger or other extraordinary transaction involving the Issuer, which if consummated would result in a change to the Issuer’s investment policy, that the Issuer take all actions and measures necessary prior to the consummation of such transaction to provide shareholders with the ability to redeem their beneficial interest in the Issuer for cash at a price equivalent to 99% of the net asset value, or NAV, per share of the Issuer.

Item 5.

The Benchmark Entities disclaim beneficial ownership of such Shares.

Mr. Daniels does not own directly any Shares.

The Reporting Persons may also, from time to time, enter into stock loan agreements with one or more counterparties in the ordinary course of business pursuant to which the Reporting Persons may lend their Shares subject to recall at their discretion.
