                               THIRD AMENDMENT TO
                                RIGHTS AGREEMENT

      This THIRD AMENDMENT TO RIGHTS AGREEMENT is entered into as of October __,
2004 by and between CardioGenesis Corporation, a California corporation formerly
known as Eclipse Surgical Technologies, Inc. (the "Company"), and Equiserve
Trust Company N.A., a national banking association (the "Rights Agent").

                                    RECITALS

      A. The Company and the Rights Agent are parties to that certain Rights
Agreement, dated August 17, 2001 and amended as of January 17, 2002 (the "Rights
Agreement");

      B. With the authorization and at the direction of its Board of Directors,
the Company wishes to amend the Rights Agreement in the following certain
respects.

                                    AGREEMENT

      Effective as of the date hereof, the Company and the Rights Agent agree as
follows:

      1. The following shall be added at the end the definition of "Acquiring
Person" contained in the Rights Agreement, amending such definition as follows:

      "The foregoing shall not apply to Laurus Master Funds, Ltd., with which
the Company entered into that certain Securities Purchase Agreement, dated as of
October __, 2004 (the "Purchase Agreement")) solely by reason of the acquisition
of Beneficial Ownership of Voting Shares pursuant to the transactions
contemplated by the Purchase Agreement. For purposes of calculating the
Beneficial Ownership of any such original Purchaser, neither the Common Shares
issuable upon conversion of the Note (as defined in the Purchase Agreement), nor
the Warrant Shares issuable pursuant to the Warrant (each as defined in the
Purchase Agreement) shall be deemed to be outstanding and Beneficially Owned
unless and until (i) such Warrant is exercised and the Warrant Shares issued
pursuant thereto, or (ii) portions of such Note are converted and Common Shares
issued pursuant thereto, as the case may be."

      2. Except as set forth in paragraph 1 above, the Rights Agreement shall
remain unchanged and in full force and effect.

                            [Signature Page Follows]

      availability of equitable and legal remedies.

            5.3 Investment Representations. Purchaser understands that the

necessary or appropriate to make an informed investment decision with respect to
the Note and the Warrant to be purchased by it under this Agreement and the Note
Shares and the Warrant Shares acquired by it upon the conversion of the Note and
the exercise of the Warrant, respectively. The Purchaser further confirms that
it has had an opportunity to ask questions and receive answers from the Company
regarding the Company's business, management and financial affairs and the terms
and conditions of the Offering, the Note, the Warrant and the Securities and to
obtain additional information (to the extent the Company possessed such
information or could acquire it without unreasonable effort or expense)
necessary to verify any information furnished to the Purchaser or to which the
Purchaser had access.

            5.4 Purchaser Bears Economic Risk. The Purchaser has substantial

capacity to protect its own interests. The Purchaser must bear the economic risk
of this investment until the Securities are sold pursuant to: (i) an effective
registration statement under the Securities Act; or (ii) an exemption from
registration is available with respect to such sale. Purchaser understands that
an investment in the Securities of the Company involves significant risks,
including those disclosed in the Company's SEC Reports, copies of which have
been provided to and reviewed by the Purchaser.

            5.5 Acquisition for Own Account. The Purchaser is acquiring the Note
and Warrant and the Note Shares and the Warrant Shares for the Purchaser's own
account for investment only, and not as a nominee or agent and not with a view

that by reason of its, or of its management's, business and financial
experience, the Purchaser has the capacity to evaluate the merits and risks of
its investment in the Note, the Warrant and the Securities and to protect its
own interests in connection with the transactions contemplated in this
Agreement, and the Related Agreements. Further, the Purchaser is aware of no

      the Company under this Agreement and the Related Agreements or (B) the

(or any other holder of the Securities) of appropriate and customary factual
representations or

<PAGE>

conformations necessary to assure compliance with applicable securities law, the
Company agrees to reissue certificates representing the Securities without the
legends set forth in Section 5.8 above at such time as:

            (a) the holder thereof is permitted to dispose of such Securities
      pursuant to Rule 144(k) under the Securities Act; or

            (b) upon resale subject to an effective registration statement after
      such Securities are registered under the Securities Act.

The Company agrees to cooperate with the Purchaser in connection with all
resales pursuant to Rule 144(d) and Rule 144(k) and provide legal opinions
necessary to allow such resales provided the Company and its counsel receive
reasonably requested representations from the selling Purchaser and broker, if
any.

            6.14 Opinion. On the Closing Date, the Company will deliver to the
Purchaser an opinion from the Company's legal counsel in the form attached
hereto as Exhibit C. The Company will provide, at the Company's expense, such
other legal opinions in the future as are reasonably necessary for the
conversion of the Note and exercise of the Warrant so long as the Company and
its counsel receive reasonably requested representations from the selling
Purchaser or holder.

            6.15 Margin Stock. The Company will not permit any of the proceeds
of the Note or the Warrant to be used directly or indirectly to "purchase" or
"carry" "margin stock" or to repay indebtedness incurred to "purchase" or
"carry" "margin stock" within the respective meanings of each of the quoted
terms under Regulation U of the Board of Governors of the Federal Reserve System
as now and from time to time hereafter in effect.

            6.16 Restricted Cash Disclosure. The Company agrees that, in
connection with its filing of its 8-K Report with the SEC concerning the
transactions contemplated by this Agreement and the Related Agreements (such
report, the "Laurus Transaction 8-K") in a timely manner after the date hereof,
it will disclose in such Laurus Transaction 8-K the amount of the proceeds of
the Note issued to the Purchaser that has been placed in a restricted cash
account and is subject to the terms and conditions of this Agreement and the
Related Agreements. Furthermore, the Company agrees to disclose in all public
filings required by the Commission (where appropriate) following the filing of
the Laurus Transaction 8-K, the existence of the restricted cash referred to in
the immediately preceding sentence, together with the amount thereof.

            6.17 Financing Right of First Refusal. (a) The Company hereby grants
to the Purchaser a right of first refusal to provide any Additional Financing
(as defined below) to be issued by the Company and/or any of its Subsidiaries,
subject to the following terms and conditions. From and after the date hereof,
prior to the incurrence of any additional indebtedness and/or the sale or
issuance of any equity interests of the Company or any of its Subsidiaries for
cash (an "Additional Financing"), the Company and/or any Subsidiary of the
Company, as the case may be, shall notify the Purchaser of its intention to
enter into such Additional Financing. In

<PAGE>

connection therewith, the Company and/or the applicable Subsidiary thereof shall
submit a fully executed term sheet (a "Proposed Term Sheet") to the Purchaser
setting forth the terms, conditions and pricing of any such Additional Financing
(such financing to be negotiated on "arm's length" terms and the terms thereof
to be negotiated in good faith) proposed to be entered into by the Company
and/or such Subsidiary. The Purchaser shall have the right, but not the
obligation, to deliver its own written proposed term sheet (the "Purchaser Term
Sheet") setting forth the terms and conditions upon which Purchaser would be
willing to provide such Additional Financing to the Company and/or such
Subsidiary. The Purchaser Term Sheet shall contain terms no less favorable to
the Company and/or such Subsidiary than those outlined in Proposed Term Sheet.
The Purchaser shall deliver such Purchaser Term Sheet within five (5) business
days of receipt of each such Proposed Term Sheet. If the provisions of the
Purchaser Term Sheet are at least as favorable to the Company and/or such
Subsidiary, as the case may be, as the provisions of the Proposed Term Sheet, as
determined by each of the Purchaser and the Company in their reasonable
discretion, the Company and/or such Subsidiary shall enter into and consummate
the Additional Financing transaction outlined in the Purchaser Term Sheet.

            (b) The Company will not, and will not permit its Subsidiaries to,
agree, directly or indirectly, to any restriction with any person or entity
which restricts the Purchaser from consummating an Additional Financing with the
Company or any of its Subsidiaries.

            (c) Notwithstanding anything to the contrary herein, this Section
6.17 shall not apply to the following: (i) the granting of options or restricted
stock to employees, officers, directors and key consultants of the Company
pursuant to any stock option plan or agreement duly adopted by the Company's
board of directors by vote of a majority of the independent members of the board
or a committee of independent directors established for such purpose, or (ii)
the exercise of any security issued by the Company in connection with the offer
and sale of the Company's securities pursuant to this Agreement, or (iii) the
exercise of or conversion of any convertible securities, options or warrants
issued and outstanding on the date hereof, provided such securities have not
been amended since the date hereof, or (iv) the issuance of securities in
connection with a joint venture or development agreement or strategic
partnership or similar agreement approved by the Company's board of directors,
no significant purpose of which is to raise equity capital, or (v) the issuance
of securities in connection with an equipment lease financing transaction or a
bank financing transaction approved by the Company's board of directors, no
significant purpose of which is to raise equity capital; (vi) the issuance of
any class of the Company's non-convertible common stock or non-convertible
preferred stock in connection with an acquisition of another business
enterprise, or the granting of options or restricted stock to employees,
officers, directors and key consultants of the target company in connection with
such an acquisition; or (vi) the exercise of or conversion of any convertible
securities, options or warrants issued and outstanding pursuant to subclauses
(i), (iv) and (v) above.

            6.18 Additional Investment. The Company agrees that the Purchaser
shall have the right (at its sole option), on or prior to the date which is 120
days following the Closing Date, to issue an additional note to the Company in
an aggregate principal amount of up to $2,000,000

<PAGE>

on the same terms and conditions (including, without limitation, the same
interest rate, the Fixed Conversion Price (as defined in the Note) then in
effect, proportionate warrant coverage (at the same exercise prices), a
proportionate amortization schedule, etc.) set forth in, and pursuant to
substantially similar documentation as, this Agreement and the Related
Agreements, provided that all such additional principal shall be disbursed
directly to the Company, and none of such additional principal shall be placed
in a restricted account.

      7. Covenants of the Purchaser. The Purchaser covenants and agrees with the
Company as follows:

            7.1 Confidentiality. The Purchaser agrees that it will not disclose,
and will not include in any public announcement, the name of the Company, unless
expressly agreed to by the Company or unless and until such disclosure is
required by law or applicable regulation, and then only to the extent of such
requirement.

            7.2 Non-Public Information. The Purchaser agrees not to effect any
sales or voluntary purchases in the shares of the Company's Common Stock while
in possession of material, non-public information regarding the Company if such
sales or voluntary purchases would violate applicable securities law, it being
expressly acknowledged and understood that no conversion of the Note effected
will result in a breach of this covenant by the Purchaser.

            7.3 No Shorting. The Purchaser represents, warrants, covenants and
agrees that neither the Purchaser nor any of its affiliates or investment
partners (i) has or, for so long as any portion of the Note shall be
outstanding, will directly or indirectly engage in any "short sales" of or using
the Company's Common Stock, or (ii) has or, for so long as any portion of the
Note shall be outstanding, will cause any person or entity to directly or
instruct any person or entity to engage in "short sales" or other hedging
transactions relating to the Company's Common Stock. To the extent that
Purchaser or its affiliates or investment partners engage in any such short
sales or hedging transactions following repayment or conversion in full of the
Note, such transactions shall only be effected in accordance with Rule 10a-1
under the Exchange Act, to the extent applicable.

      8. Covenants of the Company and Purchaser Regarding Indemnification.

            8.1 Company Indemnification. The Company agrees to indemnify, hold
harmless, reimburse and defend Purchaser, each of Purchaser's officers,
directors, agents, affiliates, control persons, and principal shareholders,
against any claim, cost, expense, liability, obligation, loss or damage
(including reasonable legal fees) of any nature, incurred by or imposed upon the
Purchaser which results, arises out of or is based upon: (i) any
misrepresentation by Company or breach of any warranty by Company in this
Agreement, any Related Agreement or in any exhibits or schedules attached hereto
or thereto; or (ii) any breach or default in performance by Company of any
covenant or undertaking to be performed by Company hereunder, or any other
agreement entered into by the Company and Purchaser relating hereto.

            8.2 Purchaser's Indemnification. Purchaser agrees to indemnify, hold
harmless, reimburse and defend the Company and each of the Company's officers,
directors,

<PAGE>

agents, affiliates, control persons and principal shareholders, at all times
against any claim, cost, expense, liability, obligation, loss or damage
(including reasonable legal fees) of any nature, incurred by or imposed upon the
Company which results, arises out of or is based upon: (i) any misrepresentation
by Purchaser or breach of any warranty by Purchaser in this Agreement or in any
exhibits or schedules attached hereto or any Related Agreement; or (ii) any
breach or default in performance by Purchaser of any covenant or undertaking to
be performed by Purchaser hereunder, or any other agreement entered into by the
Company and Purchaser relating hereto.

      9. Conversion of Convertible Note.

            9.1 Mechanics of Conversion.

            (a) Provided the Purchaser has notified the Company of the
      Purchaser's intention to sell the Note Shares and the Note Shares are
      included in an effective registration statement or are otherwise exempt
      from registration when sold: (i) Upon the conversion of the Note or part
      thereof, the Company shall, at its own cost and expense, take all
      necessary action (including the issuance of an opinion of counsel
      reasonably acceptable to the Purchaser following a request by the
      Purchaser) to assure that the Company's transfer agent shall issue shares
      of the Company's Common Stock in the name of the Purchaser (or its
      nominee) or such other persons as designated by the Purchaser in
      accordance with Section 9.1(b) hereof and in such denominations to be
      specified representing the number of Note Shares issuable upon such
      conversion; and (ii) The Company warrants that no instructions other than
      these instructions have been or will be given to the transfer agent of the
      Company's Common Stock and that after the Effectiveness Date (as defined
      in the Registration Rights Agreement) the Note Shares issued will be
      freely transferable subject to the prospectus delivery requirements of the
      Securities Act and the provisions of this Agreement, and will not contain
      a legend restricting the resale or transferability of the Note Shares.

            (b) Purchaser will give notice of its decision to exercise its right
      to convert the Note or part thereof by telecopying or otherwise delivering
      an executed and completed notice of the number of shares to be converted
      to the Company (the "Notice of Conversion"). The Purchaser will not be
      required to surrender the Note until the Purchaser receives a credit to
      the account of the Purchaser's prime broker through the DWAC system (as
      defined below), representing the Note Shares or until the Note has been
      fully satisfied. Each date on which a Notice of Conversion is telecopied
      or delivered to the Company in accordance with the provisions hereof shall
      be deemed a "Conversion Date." Pursuant to the terms of the Notice of
      Conversion, the Company will issue instructions to the transfer agent
      accompanied by an opinion of counsel within three (3) business days of the
      date of the delivery to the Company of the Notice of Conversion and shall
      cause the transfer agent to transmit the certificates representing the
      Conversion Shares to the Holder by crediting the account of the
      Purchaser's prime broker with the Depository Trust Company ("DTC") through
      its Deposit Withdrawal Agent Commission ("DWAC") system within three (3)
      business days after receipt by the Company of the Notice of Conversion
      (the "Delivery Date").

<PAGE>

            (c) The Company understands that a delay in the delivery of the Note
      Shares in the form required pursuant to Section 9 hereof beyond the
      Delivery Date could result in economic loss to the Purchaser. In the event
      that, through no fault of the Purchaser, the Company fails to direct its
      transfer agent to deliver the Note Shares to the Purchaser via the DWAC
      system within the time frame set forth in Section 9.1(b) above and the
      Note Shares are not delivered to the Purchaser by the Delivery Date, as
      compensation to the Purchaser for such loss, the Company agrees to pay
      late payments to the Purchaser for late issuance of the Note Shares in the
      form required pursuant to Section 9 hereof upon conversion of the Note in
      the amount equal to the greater of: (i) $500 per business day after the
      Delivery Date; or (ii) the Purchaser's actual damages from such delayed
      delivery. Notwithstanding the foregoing, the Company will not owe the
      Purchaser any late payments if the delay in the delivery of the Note
      Shares beyond the Delivery Date is solely out of the control of the
      Company and the Company is actively trying to cure the cause of the delay.
      The Company shall pay any payments incurred under this Section in
      immediately available funds upon demand and, in the case of actual
      damages, accompanied by reasonable documentation of the amount of such
      damages. Such documentation shall show the number of shares of Common
      Stock the Purchaser is forced to purchase (in an open market transaction)
      which the Purchaser anticipated receiving upon such conversion, and shall
      be calculated as the amount by which (A) the Purchaser's total purchase
      price (including customary brokerage commissions, if any) for the shares
      of Common Stock so purchased exceeds (B) the aggregate principal and/or
      interest amount of the Note, for which such Conversion Notice was not
      timely honored.

Nothing contained herein or in any document referred to herein or delivered in
connection herewith shall be deemed to establish or require the payment of a
rate of interest or other charges in excess of the maximum permitted by
applicable law. In the event that the rate of interest or dividends required to
be paid or other charges hereunder exceed the maximum amount permitted by such
law, any payments in excess of such maximum shall be credited against amounts
owed by the Company to a Purchaser and thus refunded to the Company.

      10. Registration Rights.

            10.1 Registration Rights Granted. The Company hereby grants
registration rights to the Purchaser pursuant to a Registration Rights Agreement
dated as of even date herewith between the Company and the Purchaser.

            10.2 Offering Restrictions. Except as previously disclosed in the
SEC Reports or in the Exchange Act Filings, or stock or stock options granted to
employees or directors of the Company (these exceptions hereinafter referred to
as the "Excepted Issuances") prior to the full repayment or conversion of the
Note (together with all accrued and unpaid interest and fees related thereto
(the "Exclusion Period"), the Company will not except with Purchaser's prior
written consent (such consent not to be unreasonably withheld), issue any (i)
debt securities with a continuously variable/floating conversion feature which
are or could be (by conversion or registration) free-trading securities (i.e.
common stock subject to a registration statement), or (ii) any equity securities
with a continuously variable/floating conversion feature which are or could be
(by conversion or registration) free-trading securities (i.e. common stock
subject to a registration statement), provided that no consent shall be
necessary on the issuance of equity

<PAGE>

securities having such a variable/floating conversion feature where the
conversion price is subject to a minimum price per share below the lesser of (i)
$0.20 and (ii) forty percent (40%) of the average trading price of the Company's
common stock for the ten (10) trading days immediately preceding such subsequent
financing, which equity securities may not be converted or otherwise exchanged
for shares of the Company's common stock.

      11. Miscellaneous.
