Gentlemen:
Pursuant to paragraph (j) of Rule 497 and the requirements of the
current EDGAR Filer Manual and Regulation S-T, we certify that the form of
prospectus and statement of additional information that would have been filed
under paragraph (c) of this section would not have differed from that contained
in the most recent registration statement (Post-Effective Amendment No.25)
which was filed electronically on June 30, 1998.
I trust the above is sufficient for your purposes.
Very truly yours,
/s/ Eva Posner
Legal Assistant
