In connection herewith and with the amended NSAR filings referenced above, the Fund
acknowledges that the disclosure included in such NSAR filings is the responsibility of the Fund.
The Fund further acknowledges that the action of the Commission or the staff acting pursuant to

Fund will not assert this action as a defense in any proceeding initiated by the Commission or any
person under the federal securities laws of the United States.
Should you have any questions or would like to discuss this matter further, please do not
hesitate to contact me at (212) 296-6960.
