                                EXPLANATORY NOTE

This Amendment No. 1 on Form 10-K/A (this "Amendment") amends the Annual Report
on Form 10-K of Cytta Corp. (the "Company") for the fiscal year ended September
30, 2009, originally filed with the Securities and Exchange Commission (the
"SEC") on January 13, 2010 (the "Original Filing"). We are filing this Amendment
for the purpose of providing the information required by the Certifications
contained in EXHIBIT 31.1 / 31.2 of the exhibit list in Part IV to Form 10-K.
Further, in connection with the filing of this Amendment and pursuant to the
rules of the SEC, we are including certain currently dated certifications with
this Amendment.

Except as expressly set forth in this Amendment, we are not amending any other
part of the Original Filing. This Amendment continues to speak as of the date of
the Original Filing, and does not reflect events occurring after the filing of
the Original Filing or modify or update any related or other disclosures unless
expressly noted otherwise. Accordingly, this Amendment should be read in
conjunction with the Original Filing and with our other filings made with the
Securities and Exchange Commission subsequent to the filing of the Original
Filing, including any amendments to those filings. The filing of this Amendment
shall not be deemed an admission that the Original Filing when made included any
untrue statement of a material fact or omitted to state a material fact
necessary to make a statement not misleading.
