<div style="TEXT-INDENT: 0pt; DISPLAY: block; MARGIN-LEFT: 0pt; MARGIN-RIGHT: 0pt" align="left"><font style="DISPLAY: inline; FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt">The Board of Directors of BTA approved the removal of BTA's non-fundamental investment policies limiting BTA's investment in residual interest municipal tender option bonds to 25% of its net assets and requiring that swaps may only be entered into with counterparties that are rated either A or A-1 or better by S&amp;P or Fitch, or A or P-1 or better by Moody's. As a result of these investment policy changes, BTA may invest more than 25% of its net assets in residual interest municipal tender option bonds, which are derivative municipal securities that have embedded in them the risk of economic leverage.</font></div>

Such counterparties may entail a greater degree of credit risk or risk of nonperformance than counterparties rated either A or A-1 or better by S&amp;P or Fitch, or A or P-1 or better by Moody's. The Manager will seek to minimize BTA&#8217;s exposure to counterparty risk by entering into swaps with counterparties the Manager believes to be creditworthy at the time they enter into such transactions. To the extent BTA engages in swaps, shareholders of BTA will be dependent on the analytical ability of the Manager to evaluate the credit quality of counterparties to such transactions. In the event of the insolvency of a counterparty, BTA may not be able to recover its assets, in full or at all, during the insolvency process. In addition, counterparties to investments may have no obligation to make markets in such investments and may have the ability to apply essentially discretionary margin and credit requirements. The foregoing investment policy amendments will not alter BTA&#8217;s investment objective.</font></div>

In fulfilling this responsibility, estimates and judgments by management are required to assess the expected benefits and related costs of controls. A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of a company's assets that could have a material effect on the financial statements.</font></div>

Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.</font></div>

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis.</font></div>
