Unless otherwise agreed in writing by Novoste and ONI, following the date hereof, Novoste shall continue to implement and execute the closing and wind down of all businesses and operations of Novoste and its Subsidiaries pursuant to and in accordance with the Wind Down Plan (Exhibit A).

(b) Periodic Updates of Wind Down Plan. From the date hereof through the date on the delivery of the Final Update, Novoste shall continuously update the Wind Down Plan to reflect the progress made in the course of the implementation and execution of Wind Down Plan and changes to the amount of the Novoste Net Cash Assets, and shall provide ONI weekly updates of the Wind Down Plan (each, an “Update”). Each such Update shall be prepared in the form of the Wind Down Plan (Exhibit A), and shall set forth and reflect, among other things, (A) any and all material changes with respect to Novoste and the Wind Down Plan, (B) any inventory or capital assets sold, (C) any accounts receivable collected, any accounts payable paid and any other expenses incurred, (D) any pending or threatened litigations, claims and other Liabilities that are not reflected on the Wind Down Plan (Exhibit A), (E) any event or fact that occurs, or of which Novoste becomes aware that could reasonably affect the estimate of any litigation, claim and other Liability specified in the Wind Down Plan (Exhibit A), (F) such other information reasonably requested by ONI, and (G) a calculation of the amount of the Novoste

Net Cash Assets as of the date of such Update. The Updates shall not include updates to the Worksheet. The Updates shall not be binding on ONI (whether or not ONI disputes any Update at any time after it is submitted).

(c) Determination Date Update; Determination Date Worksheet; Determination Date Calculations. On the next business day after the adoption of the Novoste Stockholder Approvals (the “Determination Date”), ONI shall deliver to Novoste a certificate setting forth the number of Total ONI Effective Time Common Stock (with breakdown to the categories described in Section 2.7(c)(xii)) and the number of Total ONI Effective Time Series A, which Novoste shall use in preparing the Determination Date Worksheet. On the Determination Date, Novoste shall deliver to ONI a draft Final Calculation Statement through such date (the “Determination Date Update”), based on the actual results of the implementation and execution of the Wind Down Plan (including, without limitation, expenses incurred and accounts receivable collected) through and as of such date. The Determination Date Update shall be certified on behalf of Novoste by its Chief Financial Officer and Chief Executive Officer. Along with such Determination Date Update, Novoste shall deliver to ONI a worksheet prepared in the form of the Worksheet and certified on behalf of Novoste by its Chief Financial Officer and Chief Executive Officer (the “Determination Date Worksheet”) setting forth (A) a confirmation by Novoste of the Total Novoste Effective Time Shares, with breakdown to the categories described in Section 2.7(c)(xi), (B) Novoste’s good faith detailed calculation in accordance with Section 2.7 of (1) the amount of the Novoste Net Cash Assets as of the Determination Date, and (2) the resulting Total Consideration Shares and the Common Stock Exchange Ratio and the Series A Exchange Ratio (the calculations reflected on the Determination Date Worksheet are collectively referred to herein as the “Determination Date Calculations”). Absent a manifest error, the Determination Date Update, the Determination Date Worksheet and the Determination Date Calculations (including, without limitation, the amount of the Novoste Net Cash Assets, the number of Total Consideration Shares, the Common Stock Exchange Ratio and the Series A Exchange Ratio set forth therein), shall be binding upon Novoste.

No later than three business days after receipt by ONI of the Determination Date Update and the Determination Date Worksheet, ONI shall deliver to Novoste written notice (“Response Notice”) specifying whether ONI concurs with the Determination Date Update, the Determination Date Worksheet and the Determination Date Calculations, or disputes any aspect of such materials (other than matters for which a specified dollar amount has been stipulated in the Preliminary Calculation Statement absent the occurrence of specific events, which events have not occurred between the date hereof and the delivery by Novoste of the Determination Date Update). In the event that the Response Notice indicates that ONI concurs with such materials, or in the event that ONI does not deliver a Response Notice within such three business days, (i) the Determination Date Update shall constitute the Final Calculation Statement and (ii) the Determination Date Update, the Determination Date Worksheet and the Determination Date Calculations shall be binding upon ONI for all purposes of determining the amount of the Novoste Net Cash Assets, the Total Consideration Shares, the Common Stock Exchange Ratio and the Series A Exchange Ratio. In the event that the Response Notice indicates that ONI disputes any aspect of the Determination Date Update (other than matters for which a specified dollar amount has been stipulated in the Preliminary Calculation Statement absent the occurrence of specific events, which events have not occurred

between the date hereof and the delivery by Novoste of the Determination Date Update), the Determination Date Worksheet or the Determination Date Calculations (such notice, an “Objection Notice”), such Objection Notice must include a reasonably detailed explanation of the reasons for ONI’s objection and a proposed calculation of the amount of the Novoste Net Cash Assets, the number of Total Consideration Shares, the Common Stock Exchange Ratio and the Series A Exchange Ratio (the “ONI Calculations”). Absent a manifest error, the ONI Calculations shall be binding upon ONI. Without limiting the provisions of Section 7.6, to enable ONI to evaluate the Determination Date Update, the Determination Date Worksheet and the Determination Date Calculations Novoste shall, and shall cause it Subsidiaries to, fully cooperate and assist ONI and its representatives, and make available to ONI and its representatives all of the personnel, properties, contracts, books and records, and all other documents, data and information of Novoste and its Subsidiaries, including those relating to the Wind Down Plan and its implementation and execution, as ONI shall request.

(e) Amicable Resolution of Disputes. In the event that ONI delivers an Objection Notice, Novoste and ONI shall attempt to amicably resolve any dispute by good faith negotiations between them during a period of 10 business days after the delivery of the Objection Notice. If Novoste and ONI resolve their disagreements over the disputed items within such 10 business days, the amount of the Novoste Net Cash Assets, the number of Total Consideration Shares, the Common Stock Exchange Ratio and the Series A Exchange Ratio to which Novoste and ONI shall agree in writing, shall be the final and binding upon Novoste and ONI, and the Determination Date Update shall be modified to reflect such resolution and shall constitute the Final Calculation Statement. In the event that Novoste and ONI fail to amicably resolve the disputes between them within such 10 business day period, each of Novoste and ONI shall have the right to terminate this Agreement in accordance with Section 9.1(k) by giving the other party written notice thereof. For the avoidance of doubt, with respect to matters for which a specified dollar amount has been stipulated in the Preliminary Calculation Statement, absent the occurrence of specific events, if such specific events have not occurred between the date hereof and the delivery by Novoste of the Determination Date Update, the parties hereto (A) shall be bound by and may not challenge such stipulated amounts as set forth in the Preliminary Calculation Statement and (B) may not invoke the termination rights set forth in Section 9.1(k) in connection with the determination of such amounts.

(a) Basis for ONI Valuation Adjustment.

As described in further detail on Exhibit B, the ONI Valuation shall not be adjusted if (i) ONI achieves at least 75% of the Target, or (ii) ONI exceeds the Target by no more than 125%.

Along with such certificate, ONI shall deliver to Novoste copies of such supporting material as shall be reasonably required to evidence such shipment and order information.

(a) If ONI does not achieve at least 55% of the Target, as determined pursuant to Section 2.9, Novoste shall have the right to terminate this Agreement by written notice to ONI in accordance with Section 9.1(l) within five business days after delivery to Novoste of the certificate referred to in Section 2.9(d). If Novoste does not terminate this Agreement within such five business day period, Novoste shall be deemed to have agreed that 55% of the Target has been achieved by ONI, and the ONI Valuation shall be $17,000,000.

(b) If the amount of the Novoste Net Cash Assets as finally determined pursuant to Sections 2.7 and 2.8 shall be less than $10,000,000, ONI shall have the right to terminate this Agreement by written notice to Novoste in accordance with Section 9.1(l) within five business days after such final determination. If ONI does not terminate this Agreement within such five business day period, ONI shall be deemed to have agreed that the amount of the Novoste Net Cash Assets is equal to $10,000,000, and the Novoste Valuation shall be calculated based on such amount.

(c) If ONI exceeds the Target by more than 145%, as determined pursuant to Section 2.9, then ONI shall have the right to terminate this Agreement by written notice to Novoste in accordance with Section 9.1(l) within five business days after delivery of the certificate referred to in Section 2.9(d). If ONI does not terminate this Agreement within such five business day period, ONI shall be deemed to have agreed that 145% of the Target has been achieved by ONI, and the ONI Valuation shall be $23,000,000.

(d) If the amount of the Novoste Net Cash Assets, as finally determined pursuant to Sections 2.7 and 2.8, shall exceed the ONI Valuation minus one dollar, the Novoste Valuation shall be fixed at an amount equal to the ONI Valuation minus one dollar; however, Novoste shall be permitted, prior to Closing, to distribute as a dividend or other distribution an amount of cash or property to its shareholders equal to (i) the amount of the Novoste Net Cash Assets minus (ii) the amount equal to the ONI Valuation minus one dollar.

(a) Exchange Agent. American Stock Transfer and Trust Company, 59 Maiden Lane, New York, New York 10038, or such other Person or entity reasonably acceptable to Novoste and ONI, shall be designated by Novoste and ONI to act as the exchange agent (the “Exchange Agent”) in the Merger.

(b) Delivery of Novoste Common Stock to Exchange Agent. At or prior to the Effective Time, Novoste shall deliver or make available to the Exchange Agent for exchange in accordance with this Article II, the shares of Novoste Common Stock issuable in exchange for outstanding shares of ONI Capital Stock (the “Exchange Fund”). The number of shares to be so delivered shall be equal to the number of the Total Consideration Shares.

(c) Exchange Procedures. No later than the first business day after the Effective Time, Novoste shall cause the Exchange Agent to mail to each holder of record of a certificate or certificates (“Certificates”) that immediately prior to the Effective Time represented outstanding shares of ONI Capital Stock which were converted into the right to receive Novoste Common Stock pursuant to Section 2.6, (i) a letter of transmittal in customary form (that shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and shall contain such other provisions as Novoste may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of Novoste Common Stock, and (iii) instructions for completion of exercise of rights under DGCL for Dissenting Shares. Upon surrender of a Certificate for cancellation to the Exchange Agent, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor (and Novoste shall cause the Exchange Agent to promptly deliver) a certificate representing the number of whole shares of Novoste Common Stock which such holder has the right to receive pursuant to Section 2.6, rounded down to the nearest whole share (and cash will be paid in lieu of fractional shares in accordance with Section 2.13). Any Certificate so surrendered shall forthwith be canceled. Until so surrendered, outstanding Certificates will be deemed from and after the Effective Time, for all corporate purposes, to evidence only the right to receive upon surrender a certificate representing the number of shares of Novoste Common Stock issuable pursuant to Section 2.6. In the event of a transfer of ownership of shares of ONI Capital Stock that is not registered in the transfer records of ONI, a certificate representing the proper number of whole shares of Novoste Common Stock may be issued to a transferee if the Certificate representing such shares of ONI Capital Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid.

2.12 Other Adjustments to Exchange Ratios. To the extent not already taken into account in computing the Common Stock Exchange Ratio or the Series A Exchange Ratio pursuant to the other provisions of this Article II, in the event that, prior to the Effective Time, any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Novoste Common Stock or ONI Capital Stock), reorganization, recapitalization, reclassification or other similar change shall be affected with respect to Novoste Common Stock or ONI Capital Stock, then the Common Stock Exchange Ratio and/or the Series

A Exchange Ratio shall be correspondingly adjusted to reflect appropriately the effect of such stock split, reverse stock split, stock dividend, reorganization, recapitalization, reclassification or other similar change.

2.13 Fractional Shares. No certificates representing fractional shares of Novoste Common Stock shall be issued by virtue of the Merger. All fractional shares shall be rounded down to the nearest whole number. If more than one Certificate representing shares of ONI Capital Stock shall be surrendered for the account of the same holder, the number of shares of ONI Capital Stock for which Certificates have been surrendered shall be computed on the basis of the aggregate number of shares represented by the Certificates so surrendered. Cash shall be paid in lieu of fractional shares.

2.14 Lost, Stolen or Destroyed Certificates. In the event that any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof and delivery of customary indemnification agreement, a certificate representing the shares of Novoste Common Stock into which the shares of ONI Capital Stock represented by such Certificates were converted pursuant to Section 2.6.

2.15 No Liability. Notwithstanding anything to the contrary in this Article II, neither the Exchange Agent, Novoste, the Surviving Corporation nor any party hereto shall be liable to a holder of shares of ONI Capital Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

2.16 Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of ONI Capital Stock for six months after the Effective Time shall be delivered to Novoste, upon demand, and any holders of ONI Capital Stock who have not theretofore complied with the provisions of this Article II shall thereafter look only to Novoste for the shares of Novoste Common Stock to which they are entitled by virtue of the Merger.

2.17 No Further Ownership Rights in ONI Common Stock. All shares of Novoste Common Stock issued in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of ONI Capital Stock, and there shall be no further registration of transfers on the records of the Surviving Corporation of shares of ONI Capital Stock that were outstanding immediately prior to the Effective Time. If after the Effective Time Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article II.

2.18 Tax and Accounting Consequences. It is intended by the parties hereto that the Merger shall constitute a “reorganization” within the meaning of Section 368 of the Code. The parties hereto adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Income Tax Regulations. It is intended by the parties hereto that the Merger shall be treated for accounting purposes as a purchase.

2.19 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement

and to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of ONI and Merger Sub, the officers and directors of ONI and Merger Sub will take all such lawful and necessary action. Novoste shall cause Merger Sub to perform all of its obligations relating to this Agreement and the transactions contemplated hereby.

(a) Notwithstanding any provision of this Agreement to the contrary other than Section 2.20(b), any shares of ONI Capital Stock held by a holder who has demanded and perfected appraisal rights for such shares in accordance with Section 262 of DGCL and who, as of the Effective Time, has not effectively withdrawn or lost such appraisal or dissenters’ rights (“Dissenting Shares”), shall not be converted into or represent a right to receive shares of Novoste Common Stock pursuant to Section 2.6, but instead shall be converted into the right to receive only such consideration as may be determined to be due with respect to such Dissenting Shares under DGCL. From and after the Effective Time, a holder of Dissenting Shares shall not be entitled to exercise any of the voting rights or other rights of a stockholder of the Surviving Corporation.

(b) Notwithstanding the provisions of Section 2.6(a), if any holder of shares of ONI Capital Stock who demands appraisal of such shares under DGCL shall effectively withdraw or lose (through failure to perfect or otherwise) the right to appraisal, then, as of the later of the Effective Time and the occurrence of such event, such holder’s shares shall no longer be Dissenting Shares and shall automatically be converted into and represent only the right to receive shares of Novoste Common Stock as provided in Section 2.6(a), upon surrender of the certificate representing such shares pursuant to Section 2.11.

3.10 Warranty Matters. Each product sold, leased, licensed or delivered by any ONI Group Member has been in material conformity with all applicable product specifications and contractual commitments and all express warranties and no ONI Group Member has any Liability, individually or in the aggregate (and to the Knowledge of ONI, there is no basis for any present or future action, suit, proceeding, hearing, investigation, charge, complaint, claim, or demand giving rise to any Liability) for replacement or repair thereof or other damages in connection therewith. Schedule 3.10 includes copies of the standard terms and conditions of sale of each ONI Group Member (containing applicable warranty and indemnity provisions). No product sold, leased, licensed or delivered by any ONI Group Member is subject to any guaranty, warranty, or other indemnity beyond the applicable standard terms and conditions of sale and such other indemnities and warranties disclosed on Schedule 3.10. Except as set forth on Schedule 3.10, there are no existing or, to the Knowledge of ONI, threatened product liability, warranty, failure to adequately warn or other similar claims against any ONI Group Member relating to or involving the products sold, leased, licensed or delivered by any ONI Group Member.

No notice of claim has been served against any ONI Group Member for material renegotiation or price redetermination of any business transaction relating to the business of any ONI Group Member, and, to the Knowledge of ONI, there are no facts upon which any such claim could reasonably be based.

3.11 Litigation and Proceedings. Except as set forth on Schedule 3.11, (a) there is no investigation by any Governmental Entity with respect to any ONI Group Member pending or, to the Knowledge of ONI, threatened, nor has any Governmental Entity notified any ONI Group Member of an intention to conduct the same, (b) there is no claim, action, suit, arbitration or

(a) Filing of Returns. Each ONI Group Member has timely filed all Tax Returns that it was required to file, taking into account all validly obtained extensions. All such Tax Returns were correct and complete in all material respects. All Taxes owed (whether or not shown on any Tax Return) by any ONI Group Member have been paid. No ONI Group Member is currently the beneficiary of any extension of time within which to file any Tax Return. No claim has ever been made in writing by an authority in a jurisdiction where any ONI Group Member does not file Tax Returns that it is or may be subject to taxation by that jurisdiction, which claims have not been resolved. There are no Encumbrances on any of assets of any ONI Group Member that arose in connection with any failure (or alleged failure) to pay any Tax, other than Permitted Encumbrances.

(b) Payment of Taxes. Each ONI Group Member has withheld and paid all Taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, independent contractor, creditor, stockholder or other third party.

(f) Unpaid Taxes. The unpaid Taxes of ONI Group Members (i) did not, as of the date of the ONI Balance Sheet, exceed the reserve for Tax liability (rather than any reserve for deferred Taxes established to reflect timing differences between book and Tax income) reflected on the ONI Balance Sheet, and (ii) will not exceed that reserve as adjusted for the passage of time through the Closing Date in accordance with the past custom and practice of ONI Group Members in filing their Tax Returns.

(g) No Changes in Accounting, Closing Agreement, Installment Sale. No ONI Group Member will be required to include any item of income in, or exclude any item of deduction from, taxable income for any taxable period (or portion thereof) beginning after the Closing Date as a result of any (i) change in method of accounting for a taxable period ending on or prior to the Closing Date under Code section 481(c) (or any corresponding or similar provision of state, local or foreign income Tax law), other than any such change required as a result of the transactions occurring at Closing pursuant to this Agreement, (ii) “closing agreement” as described in Code section 7121 (or any corresponding or similar provision of state, local or foreign income Tax law) executed on or prior to the Closing Date, (iii) deferred intercompany gain or any excess loss account described in Treasury Regulations under Code section 1502 (or any corresponding or similar provision of state, local or foreign income Tax law), (iv) installment sale or open transaction disposition made on or prior to the Closing Date, or (v) prepaid amount received on or prior to the Closing Date.

Each ONI Group Member has at all times fully complied with any and all tax-related requirements that the arm’s-length nature of the terms of such transactions and dealings be documented.

(j) Section 999. No ONI Group Member has participated in or cooperated with an international boycott, within the meaning of Section 999 of the Code, nor has any ONI

No ONI Group Member has a current or contingent obligation to contribute to any multiemployer plan (as defined in Section 3(37) of ERISA).

(b) ERISA . None of ONI Group Members or the ERISA Affiliates of ONI Group Members have incurred any “withdrawal liability” calculated under Section 4211 of ERISA and there has been no event or circumstance which would cause any of them to incur any such liability. No pension plan previously maintained by an ONI Group Member or an ERISA Affiliate of an ONI Group Member which was subject to Title IV of ERISA has been terminated; no proceedings to terminate any such plan have been instituted within the meaning of Subtitle C of Title IV of ERISA; and no reportable event within the meaning of Section 4043 of said Subtitle C of Title IV of ERISA with respect to which the requirement to file a notice with the Pension Benefit Guaranty Corporation has not been waived has occurred with respect to any such ONI Plan, and no liability to the Pension Benefit Guaranty Corporation has been incurred by any ONI Group Member or any ERISA Affiliate of any ONI Group Member. Except as set forth on Schedule 3.13, with respect to all ONI Plans, each ONI Group Member and each ERISA Affiliate of each ONI Group Member is in material compliance with all requirements prescribed by all statutes, regulations, orders or rules currently in effect, including any applicable foreign laws, regulations or rules in effect, and has in all material respects performed all obligations required to be performed by it. All returns, reports and disclosure statements required to be made under ERISA and the Code, or under any foreign law, regulation or rule, with respect to each ONI Plan have been timely filed or delivered, except where such failures to so file will not

have an ONI Material Adverse Effect or prevent or materially delay the consummation of the Transaction. No ONI Group Member or ERISA Affiliate of an ONI Group Member, no director, officer, employee or agent of any ONI Group Member or ERISA Affiliate of an ONI Group Member and no trustee or administrator of any trust created under an ONI Plan, has engaged in or been a party to any “prohibited transaction” as defined in Section 4975 of the Code and Section 406 of ERISA which could subject any ONI Group Member or any Affiliate of any ONI Group Member, or any director or employee of any ONI Plan or any trust relating to any ONI Plan, or any party dealing with any ONI Plan or trust relating thereto to any tax or penalty on “prohibited transactions” imposed by Section 4975 of the Code. Except as set forth on Schedule 3.13, no ONI Plan and no trust created under any ONI Plan has incurred any “accumulated funding deficiency,” as such term is defined in Section 412 of the Code and regulations issued thereunder, whether or not waived.

(c) Plan Determinations. Each ONI Plan intended to qualify under Section 401(a) of the Code has been determined by the Internal Revenue Service to so qualify, or ONI is entitled to rely on an Internal Revenue Service Opinion Letter with respect to such qualification; copies of all determination letters have been delivered or made available to Novoste, and, to the Knowledge of ONI, nothing has occurred since the date of such determination letters which might cause the loss of such qualification or exemption, or result in the imposition of any material excise tax or income tax on unrelated business income under the Code or ERISA with respect to any ONI Plan. With respect to each ONI Plan which is a qualified profit sharing plan, all employer contributions accrued for plan years ending prior to the Closing under ONI Plan terms and applicable law have been made.

(ii) there are no actions, liens, suits or claims (other than routine claims for benefits) pending or, to the Knowledge of ONI, threatened, with respect to any ONI Plan, nor is any ONI Plan the subject of any pending (or to the Knowledge of ONI, threatened) investigation or audit by the Internal Revenue Service, Department of Labor or the Pension Benefit Guaranty Corporation;

(iii) no event has occurred which presents a material risk of a partial termination (within the meaning of Section 411(d)(3) of the Code) of any ONI Plan; or

(iv) with respect to each ONI Plan that is qualified under Section 401(k) of the Code, no event has occurred with respect to which any ONI Group Member could be subject to any liability (except liability for benefits claims and funding obligations payable in the ordinary course) that is reasonably likely to have an ONI Material Adverse Effect under ERISA, the Code or any other applicable law whether of the United States or any foreign country.

(e) Certain Other Matters. Except as reserved for on the ONI Balance Sheet, no ONI Group Member has any liability or potential liability in any form whatsoever, and no ONI Group Member will have liability or potential liability in any form whatsoever, with regard to any ONI Plan, as a result of the any failure to perform non-discrimination testing on an ONI Plan or any failure to amend an ONI Plan pursuant to the legislation commonly known as “GUST” or the legislation commonly known as “EGTRRA.” All employee contributions, including elective deferrals, to 401(k) plan(s) of ONI Group Members have been segregated from the general assets of ONI Group Members and deposited into the trust(s) established pursuant to such 401(k) plan(s) in a timely manner in accordance with the “plan asset” regulations of the Department of Labor.

Except as set forth on Schedule 4.13, with respect to all Novoste Plans, each Novoste Group Member and each ERISA Affiliate of each Novoste Group Member is in material compliance with all requirements prescribed by all statutes, regulations, orders or rules currently in effect, including any applicable foreign laws, regulations or rules in effect, and has in all material respects performed all obligations required to be performed by it. All returns, reports and disclosure statements required to be made under ERISA and the Code, or any foreign law, regulation or rule, with respect to each Novoste Plan have been timely filed or delivered, except where such failures to so file will not have an Novoste Material Adverse Effect or prevent or materially delay the consummation of the Merger.

(a) As promptly as practicable after the date of this Agreement, Novoste will prepare and file with the SEC (subject, however, to compliance by Novoste with this Section 7.1(a)) a proxy statement seeking the Novoste Stockholder Approvals (the “Proxy Statement”). Novoste shall promptly notify ONI of the receipt of any comments of the SEC or the Trading Market with respect to the Proxy Statement and of any requests by the SEC or the Trading Market for any amendment or supplement thereto or for additional information, shall promptly provide to ONI copies of all correspondence between Novoste or any representative of Novoste and the SEC or the Trading Market, and shall give ONI and ONI’s counsel and accountants the opportunity to review and comment on the Proxy Statement prior to its being filed with the SEC, and shall give ONI and ONI’s counsel and accountants the opportunity to review and comment on all amendments and supplements to the Proxy Statement and all responses to requests for

additional information and replies to comments prior to their being filed with, or sent to, the SEC (it being understood and agreed that Novoste shall not file the Proxy Statement or any amendment or supplement thereto without ONI’s consent which consent shall not be unreasonably withheld). ONI will promptly furnish to Novoste all information concerning it as may be required for the Proxy Statement and any supplements or amendments thereto, including without limitation, financial statements in conformity with all applicable provisions of the Exchange Act. Novoste will cause the Proxy Statement to comply in all material respects with all applicable requirements of the Exchange Act and the rules and regulations promulgated thereunder.

(b) Promptly after the resolution of all SEC or the Trading Market comments to the Proxy Statement, Novoste shall mail at the earliest practicable date to its stockholders the Proxy Statement, which shall include all information required under applicable law to be furnished to Novoste’s stockholders in connection with the Merger, this Agreement and the transactions contemplated hereby, and the Novoste Stockholder Approvals.

(c) None of the financial or other information to be supplied by ONI or its representatives for inclusion in the Proxy Statement, including all amendments and supplements thereto, shall (A) on the date the Proxy Statement is first mailed to the stockholders of Novoste, (B) at the date of the Novoste Stockholders Meeting, and (C) at the Effective Time, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading.

(d) None of the financial or other information to be supplied by Novoste or its representatives for inclusion or incorporation by reference in the Proxy Statement, including all amendments and supplements thereto, shall, (A) on the date the Proxy Statement is first mailed to the stockholders of Novoste, (B) at the date of the Novoste Stockholders Meeting, and (C) at the Effective Time, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading.

(e) Whenever any event occurs which is required to be set forth in an amendment or supplement to the Proxy Statement, Novoste or ONI, as the case may be, will promptly inform the other of such occurrence and cooperate in filing with the SEC and/or mailing to stockholders of Novoste, such amendment or supplement.

(f) Each of Novoste and ONI will notify the other promptly upon the receipt of any comments from the SEC or its staff or any other government officials or the Trading Market in connection with any filing made pursuant hereto and of any request by the SEC or its staff or any other government officials or the Trading Market for amendments or supplements to the Proxy Statement or for additional information and will supply the other with copies of all correspondence between such party or any of its representatives, on the one hand, and the SEC, or its staff or any other government officials, or the Trading Market on the other hand, with respect to the Proxy Statement or the Merger.

7.2 Meeting of Novoste Stockholders. Promptly after the date hereof, Novoste will take all action necessary in accordance with the Florida Business Corporation Act (the “FBCA”) and its articles of incorporation and bylaws to convene a meeting of Novoste’s stockholders (the

“Novoste Stockholders Meeting”) to be held as promptly as practicable, and in any event (to the extent permissible under applicable law) within 45 days after the mailing of the Proxy Statement, for the purpose of voting upon (i) the Novoste Share Issuance, (ii) the Novoste Share Increase Charter Amendment, and (iii) the Novoste Name Change Charter Amendment. At the election of Novoste, the Novoste Stockholders Meeting may also serve as the 2005 annual meeting of Novoste stockholders and, if Novoste so elects, the Proxy Statement shall also serve as the proxy statement for such annual meeting and shall contain customary proposals regarding the election of directors and similar matters. Subject to Section 7.4, Novoste will use its reasonable efforts to solicit from its stockholders proxies in favor of the Novoste Stockholder Approvals, and will use its reasonable efforts to secure the vote of its stockholders required by the rules of the Nasdaq Stock Market or the FBCA to obtain the Novoste Stockholder Approvals. Novoste may adjourn or postpone the Novoste Stockholders Meeting to the extent necessary to ensure that any necessary supplement or amendment to the Proxy Statement is provided to Novoste’s stockholders in advance of a vote on the Novoste Stockholder Approvals or, if as of the time for which the Novoste Stockholders Meeting is originally scheduled (as set forth in the Proxy Statement) there are insufficient shares of the Novoste Common Stock represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of the Novoste Stockholders Meeting. Subject to the provisions of Section 7.4, Novoste shall ensure that the Novoste Stockholders Meeting is called, noticed, convened, held and conducted, and that all proxies solicited by Novoste in connection with the Novoste Stockholders Meeting are solicited, in compliance with the FBCA, Novoste’s articles of incorporation and bylaws, the rules of the Nasdaq Stock Market and all other applicable legal requirements.

7.3 Board of Directors of Novoste as of the Effective Time. On the Closing Date, Novoste shall deliver to ONI a written resignation, in form and substance reasonably satisfactory to ONI, from each officer and director of Novoste, other than four directors who shall be designated by Novoste and who are identified on Schedule 7.3(a) (collectively referred to as the “Novoste Remaining Directors”), effective as of the Effective Time. At the Effective Time, the Novoste Board of Directors, consisting solely of the Novoste Remaining Directors, shall appoint five new members to the Novoste Board of Directors, which members shall have been designated by ONI and are identified on Schedule 7.3(b) (the “ONI Designated Directors”). For the avoidance of doubt, immediately after the Effective Time, the Novoste Board of Directors shall consist of the Novoste Remaining Directors and the ONI Designated Directors.

(a) Novoste agrees that, during the term of this Agreement, it shall not, and it shall cause its directors, officers, employees, agents or representatives, not to, directly or indirectly, solicit, initiate, knowingly encourage or facilitate, or furnish or disclose non-public information in furtherance of, any inquiries or the making of any proposal with respect to any recapitalization, merger, consolidation or other business combination or financing involving Novoste or Merger Sub, or acquisition of any capital stock of Novoste or Merger Sub or 5% or more of the assets of Novoste or any of its Subsidiaries in a single transaction or a series of related transactions, or any acquisition by Novoste or Merger Sub of any material assets or capital stock of any other Person, or any liquidation of Novoste or Merger Sub, or any combination of the foregoing (a “Novoste Competing Transaction”), or negotiate, explore or otherwise engage in discussions with any Person (other than ONI and its directors, officers,

employees, agents and representatives) with respect to any Novoste Competing Transaction or enter into any agreement, arrangement or understanding requiring it to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement. Notwithstanding the foregoing, Novoste may engage in one or more transactions pursuant to which it may sell or transfer all or a portion of its assets (other than cash) or liabilities in consideration for the payment of cash and/or the assumption of Novoste Liabilities, and any such transaction shall not be deemed a “Novoste Competing Transaction.” Novoste will immediately cease all existing activities, discussions and negotiations with any parties conducted heretofore with respect to any proposal for a Novoste Competing Transaction.

(b) Notwithstanding anything to the contrary contained in Section 7.4(a) or in any other provision of this Agreement, Novoste and the Novoste Board of Directors shall not be prohibited from furnishing information to, or entering into discussions or negotiations with, any Person that makes a bona fide written Novoste Competing Transaction proposal to the Novoste Board of Directors after the date hereof which was not invited, initiated, solicited or knowingly encouraged, directly or indirectly, by Novoste, if (i) the Novoste Board of Directors or any committee thereof (A) determines, after consultation with Novoste’s financial advisor, that such third party has submitted to Novoste a Novoste Competing Transaction proposal which has a reasonable likelihood of resulting in a Novoste Superior Proposal (as defined in Section 7.4(e)) and (B) determines, after consultation with Novoste’s outside legal counsel, that such action is required in order for the Novoste Board of Directors to comply with its fiduciary obligations under applicable law, (ii) Novoste promptly informs ONI in writing of the identity of the potential acquirer and the material terms of such Novoste Competing Transaction proposal, and (iii) Novoste has otherwise complied with the provisions of this Section 7.4. Novoste agrees that any non-public information furnished to a potential acquirer will be pursuant to a confidentiality agreement on terms no less favorable to Novoste than the confidentiality provisions contained in this Agreement. Novoste will inform ONI promptly of any related developments, discussions and negotiations with respect to the Novoste Competing Transaction proposal (including the terms and conditions of the Novoste Competing Transaction proposal and any modifications or changes thereto).

(i) withdraw or modify, or publicly propose to withdraw or modify, in a manner adverse to ONI, (A) the approval by the Novoste Board of Directors or a committee thereof of (1) this Agreement and the Merger, (2) the Novoste Share Issuance, (3) the Novoste Share Increase Charter Amendment, and (4) the Novoste Name Change Charter Amendment or (B) the recommendation by the Novoste Board of Directors or a committee thereof to the stockholders of Novoste to vote in favor of (1) the Novoste Share Issuance, (2) the Novoste Share Increase Charter Amendment, and (3) the Novoste Name Change Charter Amendment;

(ii) approve or recommend, or propose publicly to approve or recommend, any Novoste Competing Transaction proposal;

(iii) cause Novoste to enter into, approve or recommend, or propose publicly to approve or recommend, or execute, any letter of intent, agreement in principle,

merger agreement, acquisition agreement, option agreement or other agreement relating to any Novoste Competing Transaction or agree or propose to agree to do any of the foregoing; or

(iv) submit any Novoste Competing Transaction proposal at the Novoste Stockholders Meeting or any other stockholders meeting for purposes of voting upon approval and adoption of a Novoste Competing Transaction proposal.

(d) Notwithstanding Section 7.4(c), at anytime prior to the adoption of the Novoste Stockholder Approvals, the Novoste Board of Directors (or any committee thereof) may withdraw, amend or modify its approvals and recommendations, as set forth in Section 7.4(c), in a manner adverse to ONI if (i) the Novoste Board of Directors determines in good faith, after having taken into account the advice of Novoste’s outside legal counsel, that, the withdrawal, amendment, or modification of the Novoste Board of Directors’ approvals and recommendations is required in order for the Novoste Board of Directors to comply with its fiduciary obligations to Novoste’s stockholders under applicable law, and (ii) the Novoste Board of Directors provides ONI with at least five business days prior notice of its intention to withdraw, amend or modify its approvals and recommendations. If the reason that the Novoste Board of Directors intends to withdraw, amend or modify its approvals and recommendations is because the Novoste Board of Directors has determined that a Novoste Competing Transaction proposal is a Novoste Superior Proposal, during the five business days following Novoste’s notice (or such longer period as agreed to by the parties), Novoste in good faith shall review, with the assistance of its outside financial advisor, any ONI counter-proposal to determine if such ONI counter-proposal is at least as favorable to the Novoste stockholders as the Novoste Superior Proposal from a financial point of view. If the Novoste Board of Directors determines that the ONI counter–proposal, if any, is at least as favorable to the Novoste stockholders as the Novoste Superior Proposal from a financial point of view, Novoste and ONI shall make adjustments in the terms and conditions of this Agreement such that the Novoste Competing Transaction proposal is no longer a Novoste Superior Proposal. If the Novoste Board of Directors determines that the ONI counter-proposal is not at least as favorable to the Novoste stockholders as the Novoste Superior Proposal, or if no ONI counter-proposal is offered by ONI before the expiration of such five business day period, Novoste’s Board of Directors may terminate this Agreement pursuant to Section 9.1(i) and cause Novoste promptly thereafter to enter into an agreement with respect to such Novoste Superior Proposal.

(e) For purposes of this Agreement, a “Novoste Superior Proposal” means any bona fide written proposal (or its most recent amended or modified terms, if amended or modified) made by a potential acquirer to enter into a Novoste Competing Transaction, the effect of which would be that (i) the Novoste stockholders would beneficially own less than 50% of the voting stock, common stock and participating stock of the combined or on going entity, or (ii) the transaction would result in the sale, transfer or other disposition of all or substantially all of the assets of Novoste and Merger Sub, taken as a whole, and which (in the case of either clause (i) or (ii) above) the Novoste Board of Directors, or any committee thereof, determines in its good faith judgment, based on among other things, the advice of its financial advisor, if consummated, would result in a transaction more favorable to Novoste’s stockholders from a financial point of view than the Merger, taking into account all relevant factors (including whether such transaction is subject any material contingency to which the other party has not demonstrated its ability to overcome and whether such transaction is reasonably capable of being

completed, and any proposed changes to this Agreement that may be proposed by ONI in response to the Novoste Competing Transaction proposal); provided, however, that any such proposal shall not be deemed to be a Novoste Superior Proposal unless any financing that is required to consummate the transaction contemplated by such proposal is committed, or unless the Novoste Board of Directors, or any committee thereof, shall reasonably conclude (based on consultation with its financial advisor) that such financing is likely to be obtained by such third party on a timely basis.

(f) Nothing in this Section 7.4 or elsewhere in this Agreement shall prohibit Novoste or the Novoste Board of Directors from taking or disclosing to its stockholders a position contemplated by Rules 14d-9 and 14e-2 promulgated under the Exchange Act.

(a) ONI agrees that, during the term of this Agreement, it shall not, and it shall cause its directors, officers, employees, agents or representatives, not to, directly or indirectly, solicit, initiate, knowingly encourage or facilitate, or furnish or disclose non-public information in furtherance of, any inquiries or the making of any proposal with respect to any recapitalization, merger, consolidation or other business combination or financing involving ONI, or acquisition of any capital stock of ONI or 5% or more of the assets of ONI or any of its Subsidiaries, excluding sales of Product in the ordinary course of business, in a single transaction or a series of related transactions, or any acquisition by ONI of any material assets or capital stock of any other Person, or any liquidation of ONI, or any combination of the foregoing (an “ONI Competing Transaction”), or negotiate, explore or otherwise engage in discussions with any Person (other than Novoste and its directors, officers, employees, agents and representatives) with respect to any ONI Competing Transaction or enter into any agreement, arrangement or understanding requiring it to abandon, terminate or fail to consummate the Merger or any other transaction contemplated by this Agreement. ONI will immediately cease all existing activities, discussions and negotiations with any parties conducted heretofore with respect to any proposal for an ONI Competing Transaction.

(b) Notwithstanding anything to the contrary contained in Section 7.5(a) or in any other provision of this Agreement, ONI and the ONI Board of Directors shall not be prohibited from furnishing information to, or entering into discussions or negotiations with, any Person that makes a bona fide written ONI Competing Transaction proposal to the ONI Board of Directors after the date hereof which was not invited, initiated, solicited or knowingly encouraged, directly or indirectly, by ONI, if (i) the ONI Board of Directors or any committee thereof (A) determines that after consultation with ONI’s financial advisor, such third party has submitted to ONI an ONI Competing Transaction proposal which has a reasonable likelihood of resulting in an ONI Superior Proposal (as defined in Section 7.5(e)) and (B) determines, after consultation with ONI’s outside legal counsel, that such action is required in order for the ONI Board of Directors to comply with its fiduciary obligations under applicable law, (ii) ONI promptly informs Novoste in writing of the identity of the potential acquirer and the material terms of such ONI Competing Transaction proposal, and (iii) ONI has otherwise complied with the provisions of this Section 7.5. ONI agrees that any non-public information furnished to a potential acquirer will be pursuant to a confidentiality agreement on terms no less favorable to ONI than the confidentiality provisions contained in this Agreement. ONI will inform Novoste

promptly of any related developments, discussions and negotiations with respect to the ONI Competing Transaction proposal (including the terms and conditions of the ONI Competing Transaction proposal and any modifications or changes thereto).

(i) withdraw or modify, or publicly propose to withdraw or modify, in a manner adverse to Novoste, (A) the approval by the ONI Board of Directors or a committee thereof of this Agreement and the Merger, or (B) the recommendation by the ONI Board of Directors or a committee thereof to the stockholders of ONI to vote in favor of this Agreement and the Merger;

(ii) approve or recommend, or propose publicly to approve or recommend, any ONI Competing Transaction proposal;

(iii) cause ONI to enter into, approve or recommend, or propose publicly to approve or recommend, or execute, any letter of intent, agreement in principle, merger agreement, acquisition agreement, option agreement or other agreement relating to any ONI Competing Transaction or agree or propose to agree to do any of the foregoing; or

(iv) submit any ONI Competing Transaction proposal to the ONI stockholders for purposes of voting upon approval and adoption of an ONI Competing Transaction proposal.

(d) Notwithstanding Section 7.5(c), at anytime prior to the adoption of this Agreement, the ONI Board of Directors (or any committee thereof) may withdraw, amend or modify its approvals and recommendations, as set forth in Section 7.5(c), in a manner adverse to Novoste if (i) the ONI Board of Directors determines in good faith, after having taken into account the advice of ONI’s outside legal counsel, that, the withdrawal, amendment, or modification of the ONI Board of Directors’ approvals and recommendations is required in order for the ONI Board of Directors to comply with its fiduciary obligations to ONI’s stockholders under applicable law, and (ii) the ONI Board of Directors provides Novoste with at least five business days prior notice of its intention to withdraw, amend or modify its approvals and recommendations. If the reason that the ONI Board of Directors intends to withdraw, amend or modify its approvals and recommendations is because the ONI Board of Directors has determined that an ONI Competing Transaction proposal is an ONI Superior Proposal, during the five business days following ONI’s notice (or such longer period as agreed to by the parties), ONI in good faith shall review, with the assistance of its outside financial advisor, any Novoste counter-proposal to determine if such Novoste counter-proposal is at least as favorable to the ONI stockholders as the ONI Superior Proposal from a financial point of view. If the ONI Board of Directors determines that the Novoste counter-proposal, if any, is at least as favorable to the ONI stockholders as the ONI Superior Proposal from a financial point of view, Novoste and ONI shall make adjustments in the terms and conditions of this Agreement such that the ONI Competing Transaction proposal is no longer an ONI Superior Proposal. If the ONI Board of Directors determines that the Novoste counter-proposal is not at least as favorable to the ONI stockholders as the ONI Superior Proposal, or if no Novoste counter-proposal is offered by

Novoste before the expiration of such five business day period, the ONI Board of Directors may terminate this Agreement pursuant to Section 9.1(j) and cause ONI promptly thereafter to enter into an agreement with respect to such ONI Superior Proposal.

(e) For purposes of this Agreement, an “ONI Superior Proposal” means any bona fide written proposal (or its most recent amended or modified terms, if amended or modified) made by a potential acquirer to enter into an ONI Competing Transaction, the effect of which would be that (i) the ONI stockholders would beneficially own less than 50% of the voting stock, common stock and participating stock of the combined or on going entity, or (ii) the transaction would result in the sale, transfer or other disposition of all or substantially all of the assets of the ONI Group Members, taken as a whole, and which (in the case of either clause (i) or (ii) above) the ONI Board of Directors, or any committee thereof, determines in its good faith judgment, based on among other things, the advice of its financial advisor, if consummated, would result in a transaction more favorable to ONI’s stockholders from a financial point of view than the Merger, taking into account all relevant factors (including whether such transaction is subject any material contingency to which the other party has not demonstrated its ability to overcome and whether such transaction is reasonably capable of being completed, and any proposed changes to this Agreement that may be proposed by Novoste in response to the ONI Competing Transaction proposal); provided, however, that any such proposal shall not be deemed to be an ONI Superior Proposal unless any financing that is required to consummate the transaction contemplated by such proposal is committed, or unless the ONI Board of Directors, or any committee thereof, shall reasonably conclude (based on consultation with its financial advisor) that such financing is likely to be obtained by such third party on a timely basis.

(f) Nothing in this Section 7.5 or elsewhere in this Agreement shall prohibit ONI or the ONI Board of Directors from taking or disclosing to its stockholders a position contemplated by Rule 14e-2 promulgated under the Exchange Act.

(a) The parties acknowledge that ONI and Novoste have previously executed a letter of intent, dated as of February 11, 2005, as amended (the “LOI”), which contains in Section (g) of Schedule II thereof, confidentiality provisions which will continue in full force and effect.

(b) Novoste, on the one hand, and ONI, on the other, will afford the other party and the other party’s accountants, counsel and other representatives reasonable access to its properties, books, records and personnel during the period prior to the Effective Time to obtain all information concerning the business, including the status of product development efforts, properties, results of operations and Personnel, as the other party may reasonably request. No information or knowledge obtained by a party in any investigation pursuant to this Section 7.6 will affect or be deemed to modify any representation or warranty contained herein or the conditions to the obligations of the parties to consummate the Merger.

7.7 Public Disclosure. Novoste and ONI will consult with each other, and to the extent practicable, agree, before issuing any press release or otherwise making any public statement with respect to the Merger, this Agreement, a Novoste Competing Transaction

proposal or an ONI Competing Transaction proposal and will not issue any such press release or make any such public statement prior to such consultation, except as may be required by law (including Rules 14d-9 and 14e-2 promulgated under the Exchange Act) or any listing agreement with a national securities exchange. Novoste and ONI have agreed to the text of Novoste’s press release announcing the execution of this Agreement.

(a) Upon the terms and subject to the conditions set forth in this Agreement, each of the parties agrees to use all commercially reasonable efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable to consummate and make effective, in the most expeditious manner practicable, the Merger and the other transactions contemplated by this Agreement, including using all commercially reasonable efforts to accomplish the following: (i) causing the conditions precedent set forth in Article VIII to be satisfied, (ii) obtaining all necessary actions or nonactions, waivers, consents, approvals, orders and authorizations from Governmental Entities and making all necessary registrations, declarations and filings (including registrations, declarations and filings with Governmental Entities) and taking all steps that may be necessary to avoid any suit, claim, action, investigation or proceeding by any Governmental Entity, (iii) obtaining all necessary consents, approvals or waivers from third parties, (iv) defending any suits, claims, actions, investigations or proceedings, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby, including seeking to have any stay or temporary restraining order entered by any court or other Governmental Entity vacated or reversed, and (v) executing and delivering any additional instruments necessary to consummate the transactions contemplated by, and to fully carry out the purposes of, this Agreement.

(b) Each of ONI and Novoste will give prompt notice to the other of (i) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the Merger, (ii) any notice or other communication from any Governmental Entity in connection with the Merger, (iii) any litigation relating to, involving or otherwise affecting ONI, Novoste or their respective subsidiaries that relates to the consummation of the Merger. ONI shall give prompt notice to Novoste of any representation or warranty made by it contained in this Agreement becoming untrue or inaccurate, or any failure of ONI to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, or any material adverse event involving its business or operations; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement. Novoste shall give prompt notice to ONI of any representation or warranty made by Novoste or Merger Sub contained in this Agreement becoming untrue or inaccurate, or any failure of Novoste or Merger Sub to comply with or satisfy in any material respect any covenant, condition or agreement to be complied with or satisfied by it under this Agreement, or any material adverse event involving its business or operations; provided, however, that no such notification shall affect the representations, warranties, covenants or agreements of the parties or the conditions to the obligations of the parties under this Agreement.

(a) The parties hereto agree that, from and after the Effective Time, Novoste and the Surviving Corporation shall be jointly and severally obligated to fulfill and honor in all respects the obligations of ONI pursuant to any indemnification agreement between ONI and any Person who served as a director or officer of ONI at any time prior to the Effective Time (the “ONI Indemnified Parties”) and any indemnification provisions under ONI’s certificate of incorporation or bylaws as in effect on the date hereof. The certificate of incorporation and bylaws of the Surviving Corporation shall contain provisions with respect to exculpation and indemnification that are at least as favorable in all respects to the ONI Indemnified Parties as those contained in the certificate of incorporation and bylaws of ONI as in effect on the date hereof, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would adversely affect any rights thereunder of the ONI Indemnified Parties, unless such modification is required by law. Notwithstanding the foregoing, nothing herein shall prevent the Surviving Corporation from changing its jurisdiction of incorporation so long as the certificate of incorporation (or similar instrument) and bylaws of any such successor contain provisions relating to indemnification and exculpation of the ONI Indemnified Parties (including any obligation to advance funds for expenses) that are at least as favorable in all respects to the ONI Indemnified Parties as those contained in the ONI certificate of incorporation and bylaws as in effect on the date hereof.

(b) The parties hereto agree that, from and after the Effective Time, Novoste and the Surviving Corporation shall be jointly and severally obligated to fulfill and honor in all respects the obligations of Novoste pursuant to any indemnification agreement between Novoste and any Person who served as a director or officer of Novoste at any time prior to the Effective Time (the “Novoste Indemnified Parties” and together with the ONI Indemnified Parties, the “Indemnified Parties”) and any indemnification provisions under Novoste’s articles or certificate of incorporation or bylaws as in effect on the date hereof. The articles or certificate of incorporation and bylaws of Novoste shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would adversely affect the rights thereunder of the Novoste Indemnified Parties, unless such modification is required by law. Notwithstanding the foregoing, nothing herein shall prevent Novoste from changing its jurisdiction of incorporation so long as the articles of incorporation (or similar instrument) and bylaws of any such successor contain provisions relating to indemnification and exculpation of the Novoste Indemnified Parties (including any obligation to advance funds for expenses) that are at least as favorable in all respects to the Novoste Indemnified Parties as those contained in the Novoste articles of incorporation and bylaws as in effect on the date hereof, provided, however, that if Novoste changes its jurisdiction of incorporation to the State of Delaware and the certificate of incorporation (or similar instrument) and bylaws of its successor Delaware corporation contain provisions providing for the indemnification and exculpation of the Novoste Indemnified Parties (including any obligation to advance funds for expenses) to the maximum extent permitted by the Delaware General Corporations Law, the requirements of this provision shall be deemed satisfied.

(c) For a period of six years after the Effective Time, Novoste will maintain in effect Novoste’s existing officers’ and directors’ liability insurance policy for the Novoste Indemnified Parties, or a substantially similar policy, with respect to claims arising from facts or

events that occurred on or prior to the Effective Time. The premiums for the insurance coverage pursuant to this Section 7.9(c) shall be borne by Novoste or the Surviving Corporation or any successor of Novoste or the Surviving Corporation, but shall be deemed wind down expenses and be reflected as such on the Wind Down Plan.

(d) For a period of six years after the Effective Time, Novoste shall cause the Surviving Corporation to maintain in effect ONI’s existing officers’ and directors’ liability insurance policy for the ONI Indemnified Parties, or a substantially similar policy, with respect to claims arising from facts or events that occurred on or prior to the Effective Time. The premiums for the insurance coverage pursuant to this Section 7.9(d) shall be borne by the Surviving Corporation or Novoste, or any successor of Novoste or the Surviving Corporation, but shall not be deemed wind down expenses or reflected as such on the Wind Down Plan.

(e) The parties hereto agree that, from and after the Effective Time, Novoste and the Surviving Corporation shall be jointly and severally obligated to fulfill and honor in all respects the obligations of Novoste and the Surviving Corporation, as applicable, pursuant to this Section 7.9 and agree that each of the Indemnified Parties is an intended beneficiary of the obligations of Novoste and the Surviving Corporation pursuant to this Section 7.9 and has the right to enforce them against Novoste and the Surviving Corporation, and their respective successors, with regard to himself or herself. Novoste and the Surviving Corporation also agree that, from and after the Effective Time, Novoste and the Surviving Corporation shall be jointly and severally obligated in any reorganization or similar transaction involving Novoste or the Surviving Corporation to cause, or to otherwise ensure that adequate provision is made for, a successor entity (having the ability to perform at least as well as Novoste or the Surviving Corporation immediately prior to such reorganization or similar transaction) to assume, undertake and perform all of the obligations of Novoste and the Surviving Corporation, as applicable, pursuant to this Section 7.9 so that none of the rights or benefits of the Indemnified Parties under this Section 7.9 (including the ability to exercise, enjoy and realize such rights or benefits) will be diminished by reason of such reorganization or similar transaction. This Section 7.9 shall survive the consummation of the Merger and shall be binding on all successors and assigns of the Surviving Corporation and Novoste.

7.10 Termination of Employee Stock Purchase Plan. Novoste suspended the Novoste ESPP in December 2004 and shall take no action to commence any new offering period thereunder.

7.11 Rights Agreement; Takeover Statutes. If any Florida Takeover Statute or Delaware Takeover Statute is or may become applicable to the Merger or the other transactions contemplated by this Agreement, each of Novoste and ONI and their respective boards of directors shall grant such approvals and take such lawful actions as are necessary to ensure that such transactions may be consummated as promptly as practicable on the terms contemplated by this Agreement and otherwise act to eliminate or minimize the effects of such statute and any regulations promulgated thereunder on such transactions. To the extent required, the Novoste Board of Directors shall take all further action, in addition to that referred to in Section 4.27, necessary in order to render the Rights (as such term is defined in the Rights Agreement) inapplicable to this Agreement, the Merger and the other transactions contemplated by this Agreement, including, without limitation, amending the Rights Agreement.

7.12 Restrictive Legend. Novoste will give stop transfer instructions to its transfer agent with respect to all shares of Novoste Common Stock received pursuant to the Merger, and there will be placed on the certificates representing such Novoste Common Stock, or any substitutions therefor, a legend stating in substance:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER ANY APPLICABLE STATE LAWS. THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED BY THE REGISTERED OWNER HEREOF FOR INVESTMENT AND NOT WITH A VIEW TO, OR FOR SALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE ACT. THESE SHARES MAY NOT BE SOLD, PLEDGED, TRANSFERRED OR ASSIGNED EXCEPT IN A TRANSACTION WHICH IS EXEMPT UNDER THE PROVISIONS OF THE ACT OR ANY APPLICABLE STATE SECURITIES LAWS, OR PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT OR IN A TRANSACTION OTHERWISE IN COMPLIANCE WITH APPLICABLE FEDERAL AND STATE SECURITIES LAWS.

7.13 Section 16. Provided that ONI delivers to Novoste the Section 16 Information in a timely fashion, the Novoste Board of Directors, or a committee of two or more non-employee directors thereof (as such term is defined for purposes of Rule 16b-3 under the Exchange Act), shall adopt resolutions prior to the consummation of the Merger, providing that the receipt by ONI Insiders of Novoste Common Stock upon conversion of ONI Common Stock, and of options for Novoste Common Stock upon conversion of ONI Options, in each case pursuant to the transactions contemplated by this Agreement and to the extent such securities are listed in the Section 16 Information, are intended to be exempt from liability pursuant to Section 16(b) under the Exchange Act. Such resolutions shall comply with the approval conditions of Rule 16b-3 under the Exchange Act for purposes of such Section 16(b) exemption, including, but not limited to, specifying the name of ONI Insiders, the number of securities to be acquired by each such Person, the material terms of any derivative securities, and that the approval is intended to make the receipt of such securities exempt pursuant to Rule 16b-3(d). “Section 16 Information” shall mean information regarding ONI Insiders, the number of shares of ONI capital stock held by each such ONI Insider and expected to be exchanged for Novoste Common Stock in connection with the Merger, and the number and description of ONI Options held by each such ONI Insider and expected to be converted into options for Novoste Common Stock in connection with the Merger. “ONI Insiders” shall mean those officers and directors of ONI who will be subject to the reporting requirement of Section 16(a) of the Exchange Act with respect to Novoste and who are listed in the Section 16 Information.

7.14 Performance by Merger Sub. Novoste shall cause Merger Sub to perform all obligations under this Agreement to be performed by Merger Sub, and shall be jointly and severally liable with Merger Sub for any failure to so perform or other breach of any representations, warranties, covenants, agreements or other obligations of Merger Sub hereunder.

7.15 Employee Benefit Matters. From and after the Effective Time, with respect to all current and former employees of Novoste who were employed at or prior to the Effective Time, Novoste shall (i) continue to honor its previously established policy of providing 2 months health insurance coverage to employees upon termination, such coverage to be at Novoste’s sole cost and expense and at the same benefit and coverage level (including with regards to whether such coverage applies to each such employee’s individual family members) as each such employee

had elected as of the time of such employee’s termination (in addition to and not exclusive of any rights employees have to obtain COBRA health insurance coverage during the 18 months following termination at each such employee’s own personal cost and expense), and (ii) continue to provide outplacement and severance pay benefits in accordance with Novoste’s policies as in effect at the Effective Time, provided however that all such benefits shall be in compliance with Section 409A of the Code and the Treasury guidance issued thereunder. Notwithstanding the foregoing, executive officers of Novoste who have entered into written agreements as described in Section 8.2(c) hereof shall receive health insurance benefits upon termination as described in such agreement and Section 8.2(c) hereof.

9.5 Extension; Waiver. At any time prior to the Effective Time, Novoste (with respect to ONI) and ONI (with respect to Novoste and Merger Sub) by action taken or authorized by their respective boards of directors, may, to the extent legally allowed, (a) extend the time for the performance of any of the obligations or other acts of such party, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto, and (c) subject to Section 9.4, waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Delay in exercising any right under this Agreement shall not constitute a waiver of such right.

10.1 Non-Survival of Representations and Warranties. The representations and warranties of ONI, Novoste and Merger Sub contained in this Agreement shall terminate at the Effective Time, and only the covenants and agreements that by their terms survive the Effective Time shall survive the Effective Time.

10.2 Notices. All notices and other communications hereunder shall be in writing and shall be deemed given upon delivery either personally or by commercial delivery service, or sent via facsimile (receipt confirmed) to the parties at the following addresses or facsimile numbers (or at such other address or facsimile numbers for a party as shall be specified by like notice):

10.3 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party, it being understood that all parties need not sign the same counterpart.

10.4 Entire Agreement; Third Party Beneficiaries. This Agreement, the Exhibits and Schedules hereto, and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, it being understood that the confidentiality provisions contained in Section (g) of Part II of the LOI shall continue in full force and effect until the Closing and shall survive any termination of this Agreement; and (b) are not intended to confer upon any other Person any rights or remedies hereunder, except as specifically provided in Section 7.9.

10.5 Severability. In the event that any provision of this Agreement or the application thereof becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. The parties further agree to negotiate in good faith to modify this Agreement to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

(a) Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in the Court of Chancery of the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity.

(b) If any action, suit or other proceeding (whether at law, in equity or otherwise) is instituted concerning or arising out of this Agreement or any transaction contemplated hereunder, the prevailing party shall recover, in addition to any other remedy

granted to such party therein, all such party’s costs and attorneys fees incurred in connection with the prosecution or defense of such action, suit or other proceeding.

10.7 Governing Law; Submission to Jurisdiction. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, regardless of the laws that might otherwise govern under applicable principles of conflicts of law thereof. The parties hereby irrevocably and unconditionally consent to submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware for any actions, suits or proceedings arising out of or relating to this Agreement (and the parties agree not to commence any action, suit or proceeding relating thereto except in such court), and further agree that service of any process, summons, notice or document by U.S. certified mail shall be effective service of process for any action, suit or proceeding brought against the parties in such court. The parties hereby irrevocably and unconditionally waive any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement, in the Court of Chancery of the State of Delaware, and hereby further irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum.

10.8 Rules of Construction. The parties agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

10.9 Assignment. No party may assign, in whole or in part, by operation of law or otherwise, either this Agreement or any of its rights, interests, or obligations hereunder without the prior written consent of the other parties hereto. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns. Any purported assignment in violation of this Section shall be void.

10.10 Waiver Of Jury Trial. EACH OF NOVOSTE, ONI AND MERGER SUB HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF NOVOSTE, ONI OR MERGER SUB IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

IN WITNESS WHEREOF the parties hereto have caused this Agreement and Plan of Merger to be executed by their duly authorized respective officers as of the date first written above.
