                                EXPLANATORY NOTE

                            ------------------------


    On June 23, 2000, Breakaway Solutions, Inc. ("Breakaway") filed a
Registration Statement on Form S-1 (File No. 333-40056) registering shares (the
"Shares") of Breakaway common stock, par value $0.000125 per share (the "Common
Stock"), in connection with Breakaway's obligations under a Registration Rights
Agreement, dated as of May 26, 2000 (the "Registration Rights Agreement"), by
and among Breakaway and The Putnam OTC and Emerging Growth Fund, Putnam Funds
Trust-Putnam New Century Growth Fund, Putnam Voyager Fund II, and Putnam
Investment Funds-Putnam Worldwide Equity Fund (collectively, the "Investors").
On November 11, 2000, Breakaway filed Post-Effective Amendment No. 1 to the
Registration Statement on Form S-1 (File No. 333-40056) for the purpose of,
among other things, converting such registration statement into a Registration
Statement on Form S-3.



    Breakaway registered an aggregate of 2,300,044 shares of Common Stock under
the Registration Statement on Form S-3, pursuant to which an aggregate of
1,550,000 shares of Common Stock were sold thereunder.



    Breakaway has been notified that the Investors have sold the Shares and
therefore the offering has terminated and Breakaway no longer has an obligation
to maintain the effectiveness of the registration statement. Accordingly, this
Post-Effective Amendment No. 2 is being filed for the purpose of deregistering
all remaining unsold shares of Common Stock previously registered pursuant to
the Registration Statement on Form S-3.


                                   SIGNATURE


    Pursuant to Rule 478 promulgated under the Securities Act of 1933, as
amended, the Registrant duly caused this Post-Effective Amendment No. 2 to
Registration Statement on Form S-3 to be signed on its behalf by the
undersigned, thereunto duly authorized, in Boston, Commonwealth of
Massachusetts, on the 7th day of May, 2001.


                                          BREAKAWAY SOLUTIONS, INC.
