This Post-Effective Amendment No. 1 to the Registrant's Registration Statement on Form N-14 (File No. 333-130530) (the "N-14 Registration Statement") consists of the following: (1) Facing Sheet of this Registration Statement (2) Part C of this Registration Statement (including signature page). Parts A and B to the N-14 Registration Statement are unchanged from the Proxy Statement and Prospectus filed on February 3, 2006 contained in Pre-Effective Amendment No. 3 to the Fund's N-14 Registration Statement. This Post-Effective Amendment No. 1 to the N-14 Registration Statement is being filed solely to file a tax opinion of Sidley Austin LLP, counsel for the Registrant, as Exhibit 12 to the N-14 Registration Statement. The tax opinion relates to the reorganization of Lebenthal New Jersey Municipal Bond Fund, a series of Lebenthal Funds, Inc., into BlackRock New Jersey Municipal Bond Fund (formerly known as Merrill Lynch New Jersey Municipal Bond Fund), a series of the Registrant. PART C OTHER INFORMATION Item 15. Indemnification. Section 5.3 of the Registrant's Declaration of Trust provides as follows: "The Trust shall indemnify each of its Trustees, officers, employees and agents (including persons who serve at its request as directors, officers or trustees of another organization in which it has any interest as a shareholder, creditor or otherwise) against all liabilities and expenses (including amounts paid in satisfaction of judgments, in compromise, as fines and penalties and as counsel fees) reasonably incurred by him in connection with the defense or disposition of any action, suit or other proceeding, whether civil or criminal, in which he may be involved or with which he may be threatened, while in office or thereafter, by reason of his being or having been such a trustee, officer, employee or agent, except with respect to any matter as to which he shall have been adjudicated to have acted in bad faith, willful misfeasance, gross negligence or reckless disregard of his duties; provided, however, that as to any matter disposed of by a compromise payment by such person, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless the Trust shall have received a written opinion from independent legal counsel approved by the Trustees to the effect that if either the matter of willful misfeasance, gross negligence or reckless disregard of duty, or the matter of good faith and reasonable belief as to the best interests of the Trust, had been adjudicated, it would have been adjudicated in favor of such person. The rights accruing to any Person under these provisions shall not exclude any other right to which he or she may be lawfully entitled; provided that no Person may satisfy any right in indemnity of reimbursement granted herein or in Section 5.1 or to which he or she may be otherwise entitled except out of the property of the Trust, and no Shareholder shall be personally liable to any Person with respect to any claim for indemnity or reimbursement or otherwise. The Trustees may make advance payments in connection with indemnification under this Section 5.3, provided that the indemnified person shall have given a written undertaking to reimburse the Trust in the event it is subsequently determined that he is not entitled to such indemnification." Insofar as the conditional advancing of indemnification moneys for actions based upon the Investment Company Act of 1940, as amended (the "Investment Company Act"), may be concerned, such payments will be made only on the following conditions: (i) the advances must be limited to amounts used, or to be used, for the preparation or presentation of a defense to the action, including costs connected with the preparation of a settlement; (ii) advances may be made only upon receipt of a written promise by, or on behalf of, the recipient to repay that amount of the advance which exceeds the amount which it is ultimately determined that he or she is entitled to receive from the Registrant by reason of indemnification; and (iii)(a) such promise must be secured by a surety bond, other suitable insurance or an equivalent form of security which assures that any repayments may be obtained by the Registrant without delay or litigation, which bond, insurance or other form of security must be provided by the recipient of the advance, or (b) a majority of a quorum of the Registrant's disinterested, non-party Trustees, or an independent legal counsel in a written opinion, shall determine, based upon a review of readily available facts that the recipient of the advance ultimately will be found entitled to indemnification. In Section 9 of each Distribution Agreement relating to the securities being offered hereby, the Registrant agrees to indemnify the Distributor and each person, if any, who controls the Distributor within the meaning of the Securities Act of 1933, as amended ("1933 Act"), against certain types of civil liabilities arising in connection with the Registration Statement or Prospectus and Statement of Additional Information. Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to Trustees, officers and controlling persons of the Registrant and the principal underwriter pursuant to the foregoing provisions or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a Trustee, officer, or controlling person of the Registrant and the principal underwriter in C-1 connection with the successful defense of any action, suit or proceeding) is asserted by such Trustee, officer or controlling person or the principal underwriter in connection with the shares being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue.
