         On October 10, 2002, the Board of Directors of ABIOMED, Inc. (the
"Company") voted to amend the Company's 401(k) and profit sharing plan, the
ABIOMED Retirement Savings Plan (the "Plan"), such that Fidelity Management
Trust Company ("Fidelity") is scheduled to become trustee and service provider
to the Plan on or about December 1, 2002. In connection with this amendment,
Plan assets and records will be transferred from the Plan's current trustee and
service provider to Fidelity. In order to effectuate these transfers, it is
anticipated that participants in the Plan will encounter a "blackout" period
during which they will not be able to change their investment elections. This
blackout period is anticipated to begin at 3:00 p.m. EST on November 25, 2002
and continue until the assets and records have been transferred and reconciled.
This transfer and reconciliation period is anticipated to require two to six
weeks and is dependant upon coordination between the current and new trustees
and service providers.

         The Plan includes various participant investment options, including the
option to invest in Company common stock. In connection with this amendment to
the Plan, the Company provides Plan participants with the following notice:

All investment options under the Plan are subject to various risks. Participants
in the Plan are encouraged to evaluate these risks and act accordingly.
Participants are particularly encouraged to evaluate these risks in light of the
fact that participants will not be able to change their investment elections
during the blackout period.

Information regarding the investment options and their related risks are
available through numerous sources. Participants are encouraged to read the
Company's most recent filings with the U.S. Securities and Exchange Commission
(the "SEC"), including periodic reports on Forms 10-K and 10-Q, regarding
investments in the Company's common stock and to read the prospectuses of each
of the investment funds offered currently via Putnam Fiduciary Trust Company
("Putnam") and each of the investment funds which will soon be available to
participants from Fidelity. Upon written request to the Company's Human
Resources department, the Company will provide a participant, at no cost, with
copies of the Company's most recent periodic reports filed with the SEC and the
prospectuses of each of the investment funds. After the Plan asset and record
transfers occur on or about December 1, 2002, the Putnam investment funds will
no longer be investment options for participants under the Plan. After the
blackout period is over, participants will have a choice of up to fifteen
investment options, and participants can regularly change their choices if they
so desire. A designated independent financial advisor from Salomon Smith Barney
is available to Plan participants who request assistance with evaluating their
investment choices and related risks.


The Company does not make recommendations to participants regarding their
investment choices other than passing along a common investment theme that
participants should consider diversification of their investments. The Company
notes that different participants have different tolerances for risk and that
investment choices are an individual decision of which the Company is not
responsible. Participants who have questions regarding the Plan or who want help
contacting Fidelity, Salomon Smith Barney or Putnam can seek assistance from the
Company's Human Resources department.


         Pursuant to the requirements of the Securities Exchange Act of 1934,
the Registrant has duly caused this report to be signed on its behalf by the
undersigned thereunto duly authorized.
