ITEM 1. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

        On June 15, 2001 the Board of Directors of CardioGenesis Corporation
(the "Company") approved the adoption of a Shareholders Rights Plan. The
Shareholder Rights Plan, effective at the close of business on August 17, 2001,
authorizes a dividend of one preferred share purchase right (each, a "Right")
for each share of common stock, no par value per share, of the Company (the
"Common Shares") to be distributed to shareholders of record at the close of
business on August 30, 2001 (the "Record Date"). Each Right entitles the
registered holder to purchase from the Company one Preferred Share (as defined
in paragraph 5(a) below) at an exercise price of $15, subject to the detailed
terms and conditions of the Rights Agreement (the "Rights Plan") dated as of
August 17, 2001 by and between the Company and EquiServe Trust Company, a
national banking association, as the Rights Agent (the "Rights Agent").

        The following brief description is intended only to provide a general
overview and is subject to the detailed terms and conditions of the Rights Plan
which was filed with the SEC as an exhibit to the Company's form 8-K and is
incorporated by reference herein to the Company's Registration Statement on Form
8-A.

        1.     COMMON SHARE CERTIFICATES REPRESENT THE RIGHTS

        Until the Rights are triggered on the Distribution Date (as defined in
Section 2 below), (a) the Rights are not exercisable, (b) the Rights are
attached to and trade only together with the Common Shares and (c) the Company's
regular stock certificates representing Common Shares also represent the Rights
attached to such Common Shares. Common Share certificates issued after the
Record Date and prior to the Distribution Date will contain a notation
incorporating the Rights Plan by reference.

        2.     DISTRIBUTION DATE

        The "Distribution Date" is the earliest of (a) the tenth business day
following the date of the first public announcement that any person or group or
entity (other than the Company or certain related entities, and with certain
additional exceptions) has become the beneficial owner of 15% or more of the
then outstanding shares of capital stock entitled to vote in the election of
Directors of the Company (the "Voting Shares") (such person, group or entity is
an "Acquiring Person" and the date of such public announcement is the
"Acquisition Date"), (b) the tenth business day (or such later day as shall be
designated by the Board of Directors) following the date of the commencement of,
or the announcement of an intention to make, a tender offer or exchange offer,
the consummation of which would cause any person to become an Acquiring Person
or (c) the first date, on or after the Acquisition Date, upon which (i) the
Company is acquired in a merger or other business combination in which the
Company is not the surviving corporation or in which the outstanding Common
Shares are changed into or exchanged for stock or assets of another person, or
upon which (ii) 50% or more of the Company's consolidated assets or earning
power are sold (other than in transactions in the ordinary course of business).

        Upon the close of business on the Distribution Date, the Rights separate
from the Common Shares, Right certificates representing only Rights are issued
and the Rights become exercisable to purchase Preferred Shares as described in
Section 5 below.

        No Person who is the Beneficial Owner of 15% or more of the outstanding
Voting Shares as of the date of adoption of the Rights Plan is be deemed an
Acquiring Person for as long as such Person continues to be the Beneficial Owner
of 15% or more of the outstanding Voting Shares unless or until such Person
acquires, without the prior approval of the Board of Directors, Beneficial
Ownership of an amount of additional Voting Shares equal to 1% of the Voting
Shares then outstanding.

        3.     ISSUANCE OF RIGHT CERTIFICATES

        As soon as practicable following the Distribution Date, separate
certificates representing only Rights are mailed to the holders of record of
Common Shares as of the close of business on the Distribution Date, and such
separate Right certificates alone thereafter represent the Rights from and after
the Distribution Date.


                                       1
   3

        4.     EXPIRATION OF RIGHTS

        The Rights expire on August 17, 2011 which is ten years from the date of
adoption of the Rights Plan (the "Expiration Date"), unless earlier redeemed or
exchanged, or unless the Distribution Date has previously occurred and the
Rights have separated from the Common Shares, in which case the Rights will
remain outstanding for ten years from the date they separate.

        5.     EXERCISE OF RIGHTS

        Unless the Rights have expired or been redeemed or exchanged, they may
be exercised, at the option of the holders, pursuant to paragraphs (a), (b) or
(c) below. No Right may be exercised more than once or pursuant to more than one
of such paragraphs. From and after the first event of the type described in
paragraphs (b) or (c) below, each Right that is beneficially owned by an
Acquiring Person or that was attached to a Common Share that is subject to an
option beneficially owned by an Acquiring Person is void.

               (a)    Right to Purchase Preferred Shares. From and after the
close of business on the Distribution Date, each Right (other than a Right that
has become void) is exercisable to purchase one one-hundredth of a share of
Series A Preferred Stock, no par value per share, of the Company (the "Preferred
Shares"), at an exercise price of $15.00 (the "Exercise Price"). The Preferred
Shares are nonredeemable and, unless otherwise provided in connection with the
creation of a subsequent series of preferred stock, are subordinate to any other
series of the Company's preferred stock whether issued before or after the
issuance of the Preferred Shares. The Preferred Shares may not be issued except
upon exercise of Rights. The holder of a Preferred Share is entitled to receive
when, as and if declared, quarterly dividends payable in cash on the first day
of March, June, September and December in each year, commencing the first day of
the first calendar quarter after the issuance of a Preferred Share or fraction
of a Preferred Share in the amount (rounded to the nearest cent) of $0.25 per
Preferred Share ($1.00 per annum); provided, however, that the amount of such
quarterly dividend will be reduced by the amount of any dividends paid in the
same calendar quarter pursuant to the next sentence. In addition, the holders of
Preferred Shares will receive dividends or distributions for each Preferred
Share, subject to certain adjustments, equal to 100 times the cash dividends
paid with respect to, and 100 times the aggregate per share amount of any
non-cash dividends or distributions paid or made on, the Common Shares. In the
event of liquidation, the holders of Preferred Shares are entitled to receive a
liquidation payment in an amount equal to the greater of (i) $100.00 per
Preferred Share ($1.00 per one one-hundredth of a Preferred Share), plus all
accrued and unpaid dividends and distributions on the Preferred Shares, or (ii)
an amount equal to 100 times the aggregate amount to be distributed per Common
Share. Each Preferred Share has 100 votes per share (one vote per one
one-hundredth of a Preferred Share), voting together with the Common Shares. In
the event of any merger, consolidation or other transaction in which Common
Shares are exchanged, the holder of a Preferred Share is entitled to receive 100
times the amount of stock, securities, cash and/or any other property received
per Common Share. The rights of the Preferred Shares as to dividends, voting and
liquidation preferences are protected by antidilution provisions. It is
anticipated that the value of one one-hundredth of a Preferred Share should
approximate the value of one Common Share.

               (b)    Right to Purchase Common Shares of the Company. From and
after the close of business on the tenth business day following the Acquisition
Date, each Right (other than a Right that has become void) will be exercisable
to purchase, at the Exercise Price (initially $15.00), Common Shares with a
market value equal to two times the Exercise Price. If the Company does not have
sufficient Common Shares available for all Rights to be exercised, the Company
is to substitute for all or any portion of the Common Shares that would
otherwise be issuable upon the exercise of the Rights, cash, assets or other
securities having the same aggregate value as such Common Shares.

               (c)    Right to Purchase Common Stock of a Successor Corporation.
If, on or after the Acquisition Date, (i) the Company is acquired in a merger or
other business combination in which the Company is not the surviving
corporation, (ii) the Company is the surviving corporation in a merger or other
business combination in which all or part of the outstanding Common Shares are
changed into or exchanged for stock or assets of another person or (iii) 50% or
more of the Company's consolidated assets or earning power are sold (other than
in transactions in the ordinary course of business), then each Right (other than
a Right that has become void) is thereafter exercisable to purchase, at the
Exercise Price (initially $15.00), shares of common stock of the surviving


                                       2
   4

corporation or purchaser, respectively (the "Surviving Person"), with an
aggregate market value equal to two times the Exercise Price.

        6.     ADJUSTMENTS TO PREVENT DILUTION

        The Exercise Price, the number of outstanding Rights and the number of
Preferred Shares or Common Shares issuable upon exercise of the Rights are
subject to adjustment from time to time as set forth in the Rights Plan in order
to prevent dilution. With certain exceptions, no adjustment in the Exercise
Price is required until cumulative adjustments require an adjustment of at least
1%.

        7.     CASH PAID INSTEAD OF ISSUING FRACTIONAL SECURITIES

        No fractional securities will be issued upon exercise of a Right (other
than fractions of Preferred Shares that are integral multiples of one
one-hundredth of a Preferred Share and that may, at the election of the Company,
be evidenced by depositary receipts) and in lieu thereof, an adjustment in cash
shall be made based on the market price of such securities on the last trading
date prior to the date of exercise.

        8.     REDEMPTION

        At any time prior to the earlier of (a) the tenth business day following
the Acquisition Date or (b) the first event of the type giving rise to exercise
rights under Section 5(c) above, the Board of Directors may, at its option,
direct the Company to redeem the Rights in whole, but not in part, at a price of
$.001 per Right (the "Redemption Price"), and the Company will thereafter redeem
the Rights. Immediately upon such action by the Board of Directors (the date of
such action being the "Redemption Date"), the only right of the holders of
Rights thereafter is to receive the Redemption Price.

        9.     EXCHANGE

        At any time during the period of 180 days after the Acquisition Date,
the Board of Directors of the Company may, at its option, authorize and direct
the exchange of all, but not less than all, of the then outstanding Rights for
Common Shares, one one-hundredths of Preferred Shares, debt securities of the
Company, other property or any combination of the foregoing, which, as of the
date of the Board of Directors' action, has a current market price equal to the
difference between the Exercise Price and the current market price of the shares
that would otherwise be issuable upon exercise of a Right on such date (the
"Exchange Ratio"), and the Company will thereafter so exchange the Rights.
Immediately upon such action by the Board of Directors, the right to exercise
Rights shall terminate and the only right of the holders of Rights thereafter is
to receive the securities so designated by the Board of Directors in accordance
with the Exchange Ratio.

        10.    NO SHAREHOLDER RIGHTS PRIOR TO EXERCISE

        Until a Right is exercised, the holder thereof, as such, will have no
rights as a shareholder of the Company (other than rights resulting from such
holder's ownership of Common Shares), including, without limitation, the right
to vote or to receive dividends.

        11.    AMENDMENT OF RIGHTS PLAN

        The Board of Directors may, from time to time, without the approval of
any holder of Rights, direct the Company and the Rights Agent to supplement or
amend any provision of the Rights Plan in any manner, whether or not such
supplement or amendment is adverse to any holder of Rights, and the Company and
the Rights Agent will thereafter so supplement or amend such provision;
provided, however, that from and after the earliest of (a) the tenth business
day following the Acquisition Date, (b) the first event of the type giving rise
to exercise rights under Section 5(c) above or (c) the Redemption Date, the
Rights Plan cannot be supplemented or amended in any manner that would
materially and adversely affect any holder of outstanding Rights other than an
Acquiring Person or a Surviving Person.
