Forward-Looking Statements

     This Form 8-K and other reports filed by Registrant from time to time with
the Securities and Exchange Commission (collectively the "Filings") contain or
may contain forward-looking statements and information that are based upon
beliefs of, and information currently available to, Registrant's management as
well as estimates and assumptions made by Registrant's management. When used in
the Filings the words "anticipate", "believe", "estimate", "expect", "future",
"intend", "plan" or the negative of these terms and similar expressions as they
relate to Registrant or Registrant's management identify forward-looking
statements. Such statements reflect the current view of Registrant with respect
to future events and are subject to risks, uncertainties, assumptions and other
factors (including the risks contained in the section of this report entitled
"Risk Factors") relating to Registrant's industry, Registrant's operations and
results of operations and any businesses that may be acquired by Registrant.
Should one or more of these risks or uncertainties materialize, or should the
underlying assumptions prove incorrect, actual results may differ significantly
from those anticipated, believed, estimated, expected, intended or planned.

     Although Registrant believes that the expectations reflected in the
forward-looking statements are reasonable, Registrant cannot guarantee future
results, levels of activity, performance or achievements. Except as required by
applicable law, including the securities laws of the United States, Registrant
does not intend to update any of the forward-looking statements to conform these
statements to actual results. The following discussion should be read in
conjunction with Registrant's pro forma financial statements and the related
notes that will be filed by Registrant no later than July 5, 2005, as described

                      INFORMATION TO BE INCLUDED IN REPORT

                SECTION 1 - REGISTRANT'S BUSINESS AND OPERATIONS

ITEM 2.01. COMPLETION OF ACQUISITION OR DISPOSITION OF ASSETS.

     On March 7, 2005, an Agreement and Plan of Merger, dated as of March 7,
2005 (the "Merger Agreement"), was executed and delivered by and among
PerfectData Corporation (the "Company"), PerfectData Acquisition Corporation, a
newly-formed, wholly-owned subsidiary of the Company ("Merger Sub") and Sona
Mobile, Inc. ("Sona"). A copy of the Merger Agreement (without exhibits and
schedules) was previously filed as an Exhibit to a current report on Form 8-K
filed by the Company on March 11, 2005. Under the Merger Agreement, Sona is to
merge with and into Merger Sub (the "Merger"). Merger Sub would be the surviving
corporation and would change its name to Sona Mobile, Inc. ("New Sona"). In the
Merger, the shareholders of Sona (the "Sona Shareholders") would receive shares
of the Company's Series A Convertible Preferred Stock, par value $.01 per share
(the "Series A Stock"), which would be convertible into shares of the Company's
common stock, par value $.01 per share (the "Common Stock").

          (a) The Merger was consummated on April 19, 2005.

          (b) As a result of the Merger, New Sona, the wholly-owned subsidiary
of the Company, acquired all of the assets of Sona. Such assets include: cash,
accounts receivable, intangibles - principally rights to software, scientific
development rights and equipment. Sona, which was incorporated in 2003 and which
is headquartered in Toronto, Canada, develops and markets data applications for
mobile devices in the wireless data market place that enable its customers to:
(1) receive streamed data real-time on a continuous basis; (2) execute secure
transactions in real-time; (3) exchange data with corporate systems in
real-time; and (4) integrate customers' in-house information with publicly
available information of news services such as Telerate.

          (c) Sona was acquired from its shareholders - approximately 40
individuals and entities (the "Sona Shareholders") and, except for the Merger
Agreement itself, there was no material relationship between any of the Sona
Shareholders and the Company or any of its affiliates.

          (d) In the Merger, the Sona Shareholders received an aggregate of
539,733 shares of the Series A Stock, which are convertible into 25,397,414
shares Common Stock, representing approximately 76% of the Company's issued and
outstanding shares on a fully diluted basis. Also in the Merger, 28,407 shares
of Series A Stock, convertible into 1,336,706 shares of Common Stock and
representing approximately 4% of the Company's issued and outstanding shares of
Common Stock on a fully diluted basis, was issued to Sona's M&A and financial
advisor in connection with the Merger (the "Advisor").

     The former Sona Shareholders can increase their equity position in the
Company to 85% (including the shares issuable to the Advisor) if New Sona, on a
consolidated basis, has (1) revenues of at least $3,000,000 and a gross profit
margin of at least 50% for the fiscal year ending December 31, 2005 ("Fiscal
2005") or (2) Aggregate Revenues (as defined) of at least $12,000,000 and
Aggregate Gross Profit Margin (as defined) of at least 50% for Fiscal 2005 and
the fiscal year ending December 31, 2006.



     A copy of the proposed Certificate of Designations, Preferences and Rights
of the Series A Stock (the "Certificate of Designations") was previously filed
as an Exhibit to a current report on Form 8-K filed by the Company on March 11,
2005. The Company's Certificate of Incorporation authorizes the Company to issue
up to 2,000,000 shares of the Company's Preferred Stock, $.01 par value (the
"Preferred Stock"), and the Board of Directors has the authority, without
further action by the holders of the outstanding shares of the Common Stock, to
issue shares of the Preferred Stock from time to time in one or more classes or
series, to fix the number of shares constituting any class or series and the
stated value thereof, if different from the par value, and to fix the terms of
any such series or class, including dividend rights, dividend rates, conversion
or exchange rights, voting rights, rights and terms of redemption (including
sinking fund provisions), the redemption price and the liquidation preference of
such class or series.

     As set forth in the Certificate of Designations, the holders of the Series
A Stock would have, among others, the following rights in addition to conversion
rights:

          1. Dividends - quarterly non-cumulative dividends at the rate of 6%
per annum when and if declared by the Company's Board of Directors out of funds
legally available therefore;

          2. Liquidation preference per share - $5.72;

          3. Rank - senior to the Common Stock and any other class or series of
the capital stock of the Company unless the holders of 50% or more of the then
outstanding shares of the Series A Stock consent otherwise;

          4. Voting rights - (a) the holders vote, as a single class with the
holders of the Common Stock, on all matters submitted to a vote of, or the
consent of, the holders of the Common Stock, each holder of the Series A Stock
to have that number of votes equal to the largest number of whole shares of the
Common Stock as to which such shares of the Series A Stock are then convertible,
and (b) the holders vote as a separate class on any matter which could have an
adverse effect on their shares or as to which their consent is necessary; and

          5. Mandatorily convertible - mandatorily convertible into shares of
the Common Stock upon the earlier to occur of (a) the authorization of the
Company's stockholders to an amendment to the Company's Certificate of
Incorporation increasing the authorized shares of the Common Stock to such
number as, at a minimum, would permit (i) the conversion of all the shares of
the Series A Stock and (ii) the issuance of the Additional Shares or (b) the
fifth anniversary of the Closing Date.

               (e) Not applicable.

ITEM 3.02. UNREGISTERED SALES OF EQUITY SECURITIES.

     As discussed above, in connection with the Merger, the Company issued a
total of 568,140 shares of its Series A Stock to the Sona Shareholders and the
Advisor. These shares are convertible into 26,734,120 shares of Common Stock.


                                       2


     The Company relied upon Section 4(2) of the Securities Act for the offer
and sale. It believed that Section 4(2) was available because the offer and sale
did not involve a public offering and there was not general solicitation or
general advertising involved in the offer or sale.

ITEM 5.01. CHANGES IN CONTROL OF REGISTRANT.

     As described above, on April 19, 2005, the Company issued 568,140 shares of
its Series A Stock, which is convertible into 26,734,120 shares of its Common
Stock, representing approximately 80% of the total number of issued and
outstanding shares of the Company on a fully diluted basis.

     Also, on April 19, 2005, in connection with the consummation of the Merger,
the Chairman of the Board and Chief Executive Officer of the Company, Harris A.
Shapiro, resigned and three other members of its Board of Directors, Corey
Schlossman, Timothy Morgan and Tracie Savage, also resigned. The remaining
director of the Company, Bryan Maizlish, appointed three new directors, Shawn
Kreloff, John Bush and Nicholas Glinsman, to fill the vacancies resulting from
the resignations and the newly constituted board appointed the following new
officers for the Company.

          Shawn Kreloff          -   Chairman of the Board
          John Bush              -   President and Chief Executive Officer
          Nicholas H. Glinsman   -   Secretary
          Lance Yu               -   Senior Vice President-Chief Technology
                                       Officer

     Irene J. Marino will continue, on an interim basis, in her capacity as
Chief Financial Officer of the Company.

     On March 31, 2005 the Company filed an information statement (the
"Information Statement") pursuant to Section 14(f) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"), and Rule 14(f) promulgated
thereunder with respect to the Sona designees and mailed a copy of the
Information Statement to its stockholders on April 4, 2005.
