Item 29.Persons Controlled by or Under Common Control with Registrant

Not Applicable.

Item 30.Indemnification

Under the Registrant's Agreement and Declaration of Trust, as amended, any past or present Trustee or officer of the Registrant is indemnified to the fullest extent permitted by law against liability and all expenses reasonably incurred by him in connection with any action, suit or proceeding to which he may be a party or is otherwise involved by reason of his being or having been a Trustee or officer of the Registrant. The Agreement and Declaration of Trust of the Registrant does not authorize indemnification where it is determined, in the manner specified in the Declaration, that such Trustee or officer has not acted in good faith in the reasonable belief that his actions were in the best interest of the Registrant. Moreover, the Declaration does not authorize indemnification where such Trustee or officer is liable to the Registrant or its shareholders by reason of willful misfeasance, bad faith, gross negligence or reckless disregard of his or her duties.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to Trustees, officers and controlling persons of the Registrant 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 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 in the successful defense of any action, suit or proceeding) is asserted by any such Trustee, officer

or controlling person against the Registrant in connection with the securities being registered, and the Commission is still of the same opinion, 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 is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

Item 31.(a) Business and Other Connections of Investment Adviser

The Dreyfus Corporation ("Dreyfus") and subsidiary companies comprise a financial service organization whose business consists primarily of providing investment management services as the investment adviser, manager and distributor for sponsored investment companies registered under the Investment Company Act of 1940 and as an investment adviser to institutional and individual accounts. Dreyfus also serves as sub-investment adviser to and/or administrator of other investment companies. MBSC Securities Corporation, a wholly-owned subsidiary of Dreyfus, serves primarily as a registered broker-dealer of shares of investment companies sponsored by Dreyfus and of other investment companies for which Dreyfus acts as an investment adviser, sub-investment adviser or administrator.
