NOW, THEREFORE, in consideration of the representations, warranties and covenants herein contained, the Parties agree as follows:

ARTICLE I

PURCHASE AND SALE OF THE SHARES

1.1 Purchase of the Shares from the Stockholder. Subject to and upon the terms and conditions of this Agreement, at the Closing the Stockholder shall sell, transfer, convey, assign and deliver to the Buyer, and the Buyer shall purchase, acquire and accept from the Stockholder, all of the Shares. At the Closing, the Stockholder shall deliver to the Buyer certificates evidencing the Shares duly endorsed in blank or with stock powers duly executed by the Stockholder, or such other documentation as may be required under relevant local laws to transfer title to Shares to the Buyer.

1.2 Further Assurances. At any time and from time to time after the Closing, at the Buyer’s request and without further consideration, the Stockholder shall promptly execute and deliver such instruments of sale, transfer, conveyance, assignment and confirmation, and take all such other action as the Buyer may reasonably request, to transfer, convey and assign to the Buyer, and to confirm the Buyer’s title to, all of the Shares, to put the Buyer in actual possession of the assets, properties and businesses of the Companies to assist the Buyer in exercising all rights with respect thereto and to carry out the purpose and intent of this Agreement.

1.3 Purchase Price. The base purchase price to be paid by the Buyer to the Stockholder for the Shares (the “Base Purchase Price”) shall consist of the Buyer Shares. If, prior to the Closing, there is any stock dividend, stock split or other change in the character or amount of the outstanding Buyer Common Stock, then in such event any and all new, substituted or additional shares of voting stock of the Buyer to which the Stockholder would have been entitled by reason of his ownership of the Buyer Shares had the Closing occurred prior to such event shall be considered Buyer Shares for purposes of this Agreement and the consideration to be received by the Stockholder shall be adjusted accordingly. The Base Purchase Price shall be payable in the manner described in Section 1.4. No fraction of a share of Buyer Common Stock shall be

issued, and any fractional share thereof shall be rounded to the nearest whole number. The Base Purchase Price shall be subject to adjustment after the Closing Date pursuant to the provisions of Section 1.5.

1.4 Payment of Base Purchase Price.

(a) At the Closing, the Buyer shall deliver:

(i) to the Stockholder, certificate(s) for the number of Buyer Shares minus the Escrow Shares; and

(ii) to the Escrow Agent, a certificate representing the Escrow Shares, to be held pursuant to the terms of the Escrow Agreement, as a reserve for all or part of any adjustments pursuant to Section 1.5 and to satisfy all or part of any claims for indemnity pursuant to Article VII hereof.

1.5 Post-Closing Adjustments. The Base Purchase Price shall be subject to adjustment after the Closing Date as follows:

(a) Within 60 days after the Closing Date, the Buyer shall prepare and deliver to the Stockholder the Draft Closing Balance Sheet and a certificate based on such Draft Closing Balance Sheet setting forth Buyer’s calculation of the Closing Working Capital (the “Working Capital Certificate”). The Buyer shall prepare the Draft Closing Balance Sheet and Working Capital Certificate in accordance with GAAP applied on a basis consistent with the application of GAAP to the preparation of the Financial Statements.

(b) At all reasonable times during the 90 days immediately following Stockholder’s receipt of the Draft Closing Balance Sheet and the Working Capital Certificate, Stockholder and his representatives shall be permitted to review the records of the Companies relating to the Draft Closing Balance Sheet and the Working Capital Certificate, and the Buyer shall direct any accountants engaged to prepare the Draft Closing Balance Sheet and the Working Capital Certificate, upon receipt of customary waivers, to permit Stockholder and his representatives to review such accountant’s work papers, if any, relating to the Draft Closing Balance Sheet and the Working Capital Certificate, in each case reasonably requested by Stockholder, and the Buyer shall make reasonably available to the Stockholder and his representatives the individuals employed by the Buyer and responsible for the preparation of the Draft Closing Balance Sheet and the Working Capital Certificate, in order to respond to the inquiries of the Stockholder relating thereto. The Stockholder shall deliver to the Buyer, by the Objection Deadline Date, either a notice indicating that the Stockholder accepts the Draft Closing Balance Sheet and the Buyer’s calculation of the Closing Working Capital delivered pursuant to Section 1.5(a) or a detailed statement describing its objections (if any) to the Draft Closing Balance Sheet and/or the calculation of the Closing Working Capital. If the Stockholder delivers to the Buyer a notice accepting the Draft Closing Balance Sheet and the Buyer’s calculation of the Closing Working Capital, or the Stockholder does not deliver a written objection to the Draft Closing Balance Sheet or the calculation of the Closing Working Capital by the Objection Deadline Date, then, effective as of either the date of delivery of such notice of acceptance or as of the close of business on the Objection Deadline Date, the Draft Closing Balance Sheet shall be deemed to be the Final Closing Balance Sheet and the amount of Closing Working Capital as shown on the Working Capital Certificate shall be deemed to be the Final Closing Working Capital. If the Stockholder timely objects to the Draft Closing Balance Sheet or the Buyer’s calculation of the Closing Working Capital, such objections shall be resolved as follows:

(i) The Buyer and the Stockholder shall first use reasonable efforts to resolve such objections.

(ii) If the Buyer and the Stockholder do not reach a resolution of all objections set forth on the Stockholder’s statement of objections within 30 days after delivery of such statement of objections, the Buyer and the Stockholder shall, within 30 days following the expiration of such 30-day period, engage the Accountant, pursuant to an engagement agreement executed by the Buyer, the Stockholder and the Accountant, to resolve the Unresolved Objections.

(iii) The Buyer and the Stockholder shall jointly submit to the Accountant, within 10 days after the date of the engagement of the Accountant (as evidenced by the date of the engagement agreement), a copy of the Draft Closing Balance Sheet and the Working Capital Certificate, a copy

of the statement of objections delivered by the Stockholder to the Buyer, and a statement setting forth the resolution of any objections agreed to by the Buyer and the Stockholder. Each of the Buyer and the Stockholder shall submit to the Accountant (with a copy delivered to the other Party on the same day), within 45 days after the date of the engagement of the Accountant, a memorandum (which may include supporting exhibits) setting forth their respective positions on the Unresolved Objections. Each of the Buyer and the Stockholder may (but shall not be required to) submit to the Accountant (with a copy delivered to the other Party on the same day), within 75 days after the date of the engagement of the Accountant, a memorandum responding to the initial memorandum submitted to the Accountant by the other Party. Unless requested by the Accountant in writing, neither Party may present any additional information or arguments to the Accountant, either orally or in writing.

(iv) Within 100 days after the date of its engagement hereunder, the Accountant shall determine whether or to what degree the objections raised by the Stockholder are correct and shall issue a ruling which shall include (A) a balance sheet, consisting of the Draft Closing Balance Sheet as adjusted pursuant to any resolutions to objections agreed upon by the Buyer and the Stockholder and pursuant to the Accountant’s resolution of the Unresolved Objections and (B) a calculation of the Closing Working Capital based on the balance sheet described in clause (A) of this sentence. Such balance sheet shall be deemed to be the “Final Closing Balance Sheet” and the amount of Closing Working Capital calculated based on such balance sheet shall be deemed to be the “Final Closing Working Capital.”

(v) The resolution by the Accountant of the Unresolved Objections shall be conclusive and binding upon the Buyer and the Stockholder. The Buyer and the Stockholder agree that the procedure set forth in this Section 1.5(b) for resolving disputes with respect to the Draft Closing Balance Sheet and/or the Working Capital Certificate shall be the sole and exclusive method for resolving any such disputes; provided that this provision shall not prohibit either Party from instituting litigation to enforce the ruling of the Accountant.

(vi) MDS or the Stockholder shall pay the fees and expenses of the Accountant based upon the difference between the Draft Closing Balance Sheet and the Final Closing Balance Sheet or between the Working Capital Certificate and the Closing Working Capital, as follows: (1) if either of such difference is less than $50,000, the fees and expenses of the Accountant shall be solely borne by the Stockholder; and (2) if either of such difference exceeds $50,000, the fees and expenses of the Accountant shall be solely borne by MDS.

(c) Immediately upon the expiration of the Objection Deadline Date, if no objection to the Draft Closing Balance Sheet or the calculation of the Closing Working Capital is made, or upon notification by the Stockholder to the Buyer that no objection to the Draft Closing Balance Sheet or the calculation of the Closing Working Capital will be made, or immediately upon final resolution of any dispute in connection with the determination of the Closing Working Capital pursuant to this Section 1.5, the Base Purchase Price shall be adjusted as follows:

(i) If the Final Closing Working Capital is less than the Target Amount by $250,000 or more, such deficiency shall be deducted from the Base Purchase Price (at which point such deduction shall equal the entire amount of the deficiency, and not just amounts in excess of $250,000).

(ii) If the Final Closing Working Capital is greater than the Target Amount by $250,000 or more, such excess shall be added to the Base Purchase Price (at which point such addition shall equal the entire amount of the excess, and not just amounts in excess of $250,000).

(d) The amount, if any, to be paid pursuant to Section 1.5(c)(i) shall be paid by the Stockholder to the Buyer not later than two business days following the Determination Date, first by delivery to Buyer of a number of Escrow Shares determined by dividing the amount of such deficiency by the Closing Price, to the extent a sufficient number of Escrow Shares are available, and the balance, if any, shall then be payable to the Buyer directly by the Stockholder in shares of Buyer Common Stock (at an assumed

value per share equal to the Closing Price with any fractional share rounded to the nearest whole share) and/or in cash, by cashier’s or certified check or by wire transfer of immediately available funds to an account designated by the Buyer.

(e) The amount, if any, to be paid pursuant to Section 1.5(c)(ii) shall be paid by the Buyer to the Stockholder not later than two business days following the Determination Date in shares of Buyer Common Stock (at an assumed value per share equal to the Closing Price with any fractional share rounded to the nearest whole share).

1.6 Escrow Account. The Escrow Shares shall be held by the Escrow Agent under the terms of the Escrow Agreement for the purpose of securing the indemnification obligations of the Stockholder pursuant to Article VII and any adjustments to the Base Purchase Price pursuant to Section 1.5. The Escrow Shares shall be held as a trust fund and shall not be subject to any lien, attachment, trustee process or any other judicial process of any creditor of any party, and shall be held and disbursed solely for the purposes and in accordance with the terms of the Escrow Agreement.

1.7 The Closing. The Closing shall take place at the offices of WilmerHale, 00 Xxxxx Xxxxxx, Xxxxxx, Xxxxxxxxxxxxx commencing at 9:00 a.m., local time, on the Closing Date. The transfer of the Shares by the Stockholder to the Buyer and the payment of the Base Purchase Price by the Buyer to the Stockholder shall be deemed to occur at 9:00 a.m., local time, on the Closing Date.

1.8 Stock Transfer Documents. At or before the Closing, the Stockholder shall, and shall cause the relevant Companies to, enter into and deliver separate stock purchase agreements, share transfer forms, powers of attorney, stock powers, deeds and any other documents as may be required under relevant local law to transfer title to the Shares to the Buyer under this Agreement (“Stock Transfer Documents”), with only such modifications as are necessary in order to maintain substantially the same legal meaning and effect under local law as provided in this Agreement, including but not limited to the following:

(a) Italy.

In an event that an adjustment to the Base Purchase Price is made pursuant to Section 1.5 of this Agreement, the allocation of the Base Purchase Price shall be amended to allocate such adjustment to the Shares of such Company to which such adjustment is attributable. The parties shall report the Tax consequences of the transactions contemplated by this Agreement in a manner consistent with the allocation agreed under this Section 1.9.

INDEMNIFICATION

7.1 Indemnification by the Stockholder. The Stockholder shall indemnify the Buyer in respect of, and hold it harmless against, any and all Damages incurred or suffered by the Buyer or any Affiliate thereof resulting from, relating to or constituting:

(a) any breach, as of the date of this Agreement or as of the Closing Date, of any representation or warranty of the Stockholder contained in this Agreement or any other agreement or instrument executed by the Stockholder or any of the Companies to the Buyer pursuant to this Agreement;

(b) any failure to perform any covenant or agreement of the Stockholder contained in this Agreement or any agreement or instrument furnished by the Stockholder or any of the Companies to the Buyer pursuant to this Agreement; or

(c) any failure of the Stockholder to have good, valid and marketable title to the Shares, free and clear of all Security Interests.

7.2 Indemnification by the Buyer. The Buyer shall indemnify the Stockholder in respect of, and hold him harmless against, any and all Damages incurred or suffered by the Stockholder resulting from, relating to or constituting:

(a) any breach, as of the date of this Agreement or as of the Closing Date, of any representation or warranty of the Buyer contained in this Agreement or any other agreement or instrument executed by the Buyer to the Stockholder pursuant to this Agreement; or

(b) any failure to perform any covenant or agreement of the Buyer contained in this Agreement or any agreement or instrument furnished by the Buyer to the Stockholder pursuant to this Agreement.

7.3 Indemnification Claims.

(a) An Indemnified Party shall give written notification to the Indemnifying Party of the commencement of any Third Party Action. Such notification shall be given within 20 days after receipt by the Indemnified Party of notice of such Third Party Action, and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third Party Action and the amount of the claimed Damages; provided, however, that no delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any Damages caused by or arising out of such failure. Within 20 days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Action with counsel reasonably satisfactory to the Indemnified Party; provided that (i) the Indemnifying Party may only assume control of such defense if (A) it acknowledges in writing to the Indemnified Party that any damages, fines, costs or other liabilities that may be assessed against the Indemnified Party in connection with such Third Party Action constitute Damages for which the Indemnified Party shall be indemnified pursuant to this Article VII and (B) the amount claimed as Damages is less than or equal to the amount of Damages for which the Indemnifying Party is liable under this Article VII and (ii) the Indemnifying Party may not assume control of the defense of a Third Party Action involving

criminal liability or in which equitable relief (provided, that this clause shall not apply to equitable relief for the remediation of contamination of environmental media including soils, sediments, surface water and groundwater) is sought against the Indemnified Party. If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Action, the Indemnified Party shall control such defense. The Non-controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action. The fees and expenses of counsel to the Indemnified Party with respect to a Third Party Action shall be considered Damages for purposes of this Agreement if (i) the Indemnified Party controls the defense of such Third Party Action pursuant to the terms of this Section 7.3(a) or (ii) the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes that the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Action. The Indemnifying Party shall not agree to any settlement of, or the entry of any judgment arising from, any Third Party Action without the prior written consent of the Indemnified Party, which shall not be unreasonably withheld, conditioned or delayed. The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Action without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, conditioned or delayed. In the event that the Damages require remediation of releases of Materials of Environmental Concern at properties of the Companies, the Indemnifying Party shall be entitled to remediate such releases pursuant to the least stringent standards consistent with the land use and the lease obligations existing at such properties as of the Closing Date, provided further, than any such remediation shall not adversely affect on-going commercial operations at the property.

(b) In order to seek indemnification under this Article VII, an Indemnified Party shall deliver a Claim Notice to the Indemnifying Party. If the Indemnified Party is the Buyer and is seeking to enforce such claim pursuant to the Escrow Agreement, the Indemnifying Party shall also deliver a copy of the Claim Notice to the Escrow Agent.

(c) Within 20 days after delivery of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party a Response, in which the Indemnifying Party shall: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount, (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount; or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount. In connection with any Response delivered pursuant to (i) or (ii) in the first sentence of this paragraph (c), the Indemnifying Party shall pay the Claimed Amount (in the case of clause (i)) or the Agreed Amount (in the case of clause (ii)) by delivering to the Indemnified Party such number of shares of Buyer Common Stock (or, in the case of a claim against the Stockholder, instructions to the Escrow Agent to release such number of Escrow Shares) as have an aggregate Value equal to the Claimed Amount or the Agreed Amount, as the case may be. In the case of such Response regarding a Claim Notice against the Stockholder, the Stockholder shall (A) deliver to the Escrow Agent a written notice executed by both Parties instructing the Escrow Agent to distribute to the Buyer the appropriate number of Escrow Shares and (B) to the extent there are insufficient or no remaining Escrow Shares, deliver to the Buyer original stock certificates representing the appropriate number of shares of Buyer Common Stock, together with duly executed and completed stock powers and written representations relating to ownership of and title to such shares as reasonably requested by the Buyer. For purposes of this Article VII, the “Value” of any Escrow Shares or other shares of Buyer Common Stock delivered in satisfaction of an indemnity claim shall be the average of the last reported sale prices per share of the Buyer Common Stock on the NASDAQ Global Market over the five consecutive trading days ending two trading days before such Escrow Shares are distributed by the Escrow Agent to the Buyer or such other shares of Buyer Common Stock are delivered to the Indemnified Party, as applicable, as provided above (subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock since the beginning of such five-day period), multiplied by the number of

such Escrow Shares or such other shares of Buyer Common Stock are delivered to the Indemnified Party. In the case of any such shares of Buyer Common Stock that are delivered to the Stockholder by the Buyer, such shares of Buyer Common Stock shall not be registered under the Securities Act and shall bear the following legend:

“The shares represented by this certificate have not been registered under the Securities Act of 1933, as amended, and may not be offered, sold or otherwise transferred, pledged or hypothecated unless and until such shares are registered under such Act or an opinion of counsel satisfactory to the Company is obtained to the effect that such registration is not required.”

In addition, and notwithstanding any other terms hereof, in no event shall Buyer be obligated to issue or deliver to Stockholder, pursuant to this Article VII or the Consulting Agreement, an aggregate number of shares of Buyer Common Stock representing twenty percent (20%) or more of the then-outstanding shares of Buyer Common Stock without the prior approval of Buyer’s stockholders.

(d) During the 30-day period following the delivery of a Response that reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve the Dispute. If the Dispute is not resolved within such 30-day period, such Dispute shall be resolved in a state or federal court sitting in the State of Delaware, in accordance with Section 13.9. If the Indemnified Party is the Buyer and is seeking to enforce the claim that is the subject of the Dispute pursuant to the Escrow Agreement, the Indemnifying Party and the Indemnified Party shall deliver to the Escrow Agent, promptly following the resolution of the Dispute (whether by mutual agreement, arbitration, judicial decision or otherwise), a written notice executed by both Parties instructing the Escrow Agent as to what (if any) portion of the Escrow Shares shall be distributed to the Buyer and/or the Stockholder (which notice shall be consistent with the terms of the resolution of the Dispute).

(e) Notwithstanding the other provisions of this Section 7.3, if a customer, distributor, supplier or vendor of the Companies asserts (other than by means of a lawsuit) that an Indemnified Party is liable to such customer, distributor, supplier or vendor for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this Article VII, and such Indemnified Party reasonably determines that it has a valid business reason to fulfill such obligation, then (i) such Indemnified Party shall be entitled to satisfy such obligation, without prior notice to or consent from the Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VII, and (iii) such Indemnified Party shall be reimbursed, in accordance with the provisions of this Article VII, for any such Damages for which it is entitled to indemnification pursuant to this Article VII (subject to the right of the Indemnifying Party to dispute both the Indemnified Party’s entitlement to indemnification and the amount for which it is entitled to indemnification, under the terms of this Article VII).

7.4 Survival of Representations and Warranties. All representations and warranties that are covered by the indemnification agreements in Section 7.1(a) and Section 7.2(a) shall (a) survive the Closing and (b) shall expire on the date 24 months following the Closing Date, except that (i) the representations and warranties set forth in Article II and Sections 3.1 (Organization, Qualification and Corporate Power), 3.2 (Capitalization), 3.3 (Authorization of Transaction), 4.1 (Organization, Standing and Power), 4.2 (Capitalization) and 4.3 (Authority; No Conflict; Required Filings and Consents) shall survive the Closing without limitation; (ii) the representations and warranties set forth in Sections 3.9 (Tax Matters), 3.22 (Employee Benefits), and 3.36 (Customs Matters) shall survive until 30 days following expiration of all statutes of limitation applicable to the matters referred to therein and (iii) the representations and warranties set forth in Section 3.23 (Environmental Matters) shall expire on the date 36 months following the Closing Date. If an Indemnified Party delivers to an Indemnifying Party, before expiration of a representation or warranty, either a Claim Notice based upon a breach of such representation or warranty, or an Expected Claim Notice based upon a breach of such representation or warranty, then the applicable representation or warranty shall survive until, but only for purposes of, the resolution of any claims arising from or related to the matter covered by such notice. If the legal proceeding or written claim with respect to which an Expected Claim Notice has been given is definitively withdrawn or resolved in favor of the Indemnified Party, the Indemnified Party shall promptly so

notify the Indemnifying Party; and if the Indemnified Party has delivered a copy of the Expected Claim Notice to the Escrow Agent and Escrow Shares have been retained in escrow after the Termination Date (as defined in the Escrow Agreement) with respect to such Expected Claim Notice, the Indemnifying Party and the Indemnified Party shall promptly deliver to the Escrow Agent a written notice executed by both parties instructing the Escrow Agent to distribute such retained Escrow Shares to the Stockholder in accordance with the terms of the Escrow Agreement. The rights to indemnification set forth in this Article VII shall not be affected by (i) any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or after the date of this Agreement or the Closing Date, with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder or (ii) any waiver by an Indemnified Party of any closing condition relating to the accuracy of representations and warranties or the performance of or compliance with agreements and covenants.

7.5 Limitations.

(a) Notwithstanding anything to the contrary herein, (i) the aggregate liability of the Stockholder for Damages under Section 7.1(a) shall not exceed (x) 50% of the Closing Value minus (y) $1,250,000 (such resulting amount, the “Cap Amount”) and (ii) the Stockholder shall not be liable under Section 7.1(a) unless and until the aggregate Damages for which he would otherwise be liable under Section 7.1(a) exceed $1,250,000 (the “Deductible”) (at which point the Stockholder shall become liable for the Damages under Section 7.1(a) that are in excess of the Deductible); provided, that the limitations set forth in this sentence shall not apply to a claim pursuant to Section 7.1(a) relating to a breach of the representations and warranties set forth in Article II or Sections 3.1 (Organization, Qualification and Corporate Power), 3.2 (Capitalization), 3.3 (Authorization of Transaction), 3.9 (Tax Matters), 3.22 (Employee Benefits) or 3.36 (Customs Matters), or the first or second sentence of Section 3.10(a) (Assets). For purposes solely of this Article VII, all representations and warranties of the Stockholder in Articles II and III (other than Sections 3.7 (Absence of Certain Changes) and 3.30 (Disclosure)) shall be construed as if the term “material” and any reference to “Company Material Adverse Effect” (and variations thereof) were omitted from such representations and warranties.

(b) Notwithstanding anything to the contrary herein, (i) the aggregate liability of the Buyer for Damages under Section 7.2(a) shall not exceed the Cap Amount, and (ii) the Buyer shall not be liable under Section 7.2(a) unless and until the aggregate Damages for which it would otherwise be liable under Section 7.2(a) exceed the Deductible (at which point the Buyer shall become liable for the Damages under Section 7.2(a) that are in excess of the Deductible); provided, that the limitations set forth in this sentence shall not apply to a claim pursuant to Section 7.2(a) relating to a breach of the representations and warranties set forth in Sections 4.1 (Organization, Standing and Power), 4.2 (Capitalization) or 4.3 (Authority; No Conflict; Required Filings and Consents). For purposes solely of this Article VII, all representations and warranties of the Buyer in Article IV shall be construed as if the term “material” and any reference to “Buyer Material Adverse Effect” (and variations thereof) were omitted from such representations and warranties.

(c) The Escrow Agreement is intended to secure the indemnification obligations of the Stockholder under this Agreement. However, the rights of the Buyer under this Article VII shall not be limited to the Escrow Shares nor shall the Escrow Agreement be the exclusive means for the Buyer to enforce such rights; provided that the Buyer shall not attempt to collect any Damages directly from the Stockholder unless there are no remaining Escrow Shares held in escrow pursuant to the Escrow Agreement.

(d) Except with respect to claims based on fraud or willful misrepresentation, or claims for willful breach of any covenant or agreement contained in any of the provisions referenced in Section 13.10 of this Agreement, after the Closing, the rights of the Indemnified Parties under this Article VII and the Escrow Agreement shall be the exclusive remedy of the Indemnified Parties with respect to claims resulting from or relating to any misrepresentation, breach of warranty or failure to perform any covenant or agreement contained in this Agreement, and the Indemnified Parties agree to release and relinquish any and all other claims that they may have with respect to such matters, regardless of whether such claims arise by statute, in equity or at law.

(e) The Stockholder shall have no right of contribution against the Companies with respect to any breach by any of the Companies of any of its representations, warranties, covenants or agreements.

7.6 Purchase Price Adjustment. The Buyer and the Stockholder agree to treat each indemnification payment pursuant to this Article VII as an adjustment to the Base Purchase Price for all Tax purposes and shall take no position contrary thereto unless required to do so by applicable Laws and Regulations.

ARTICLE VIII

OTHER AGREEMENTS

8.1 Proprietary Information.

(a) Except as otherwise provided in the Consulting Agreement, the Stockholder and each of his Affiliates shall hold in confidence and shall use their best efforts to have all officers, directors and personnel who continue after the Closing to be employed by the Stockholder or any Affiliate thereof to hold in confidence all knowledge and information of a secret or confidential nature with respect to the business of any Company prior to Closing and not to disclose, publish or make use of the same without the prior written consent of the Buyer, except to the extent that such information shall have become public knowledge other than by breach of this Agreement by the Stockholder or any such Affiliate.

(b) If (i) the employment of an officer, director or other employee of the Stockholder or any Affiliate thereof, to whom secret or confidential knowledge or information concerning the business of any Company prior to Closing has been disclosed, is terminated and (ii) such individual is subject to an obligation to maintain such knowledge or information in confidence after such termination, the Stockholder shall, upon request by the Buyer, take all reasonable steps at his expense to enforce such confidentiality obligation in the event of an actual or threatened breach thereof. Any legal counsel retained by the Stockholder in connection with any such enforcement or attempted enforcement shall be selected by the Stockholder, but shall be subject to the approval of the Buyer, which approval shall not be unreasonably withheld.

(c) The Stockholder agrees that the remedy at law for any breach of this Section 8.1 would be inadequate and that the Buyer shall be entitled to injunctive relief in addition to any other remedy it may have upon breach of any provision of this Section 8.1.

8.2 No Solicitation or Hiring of Former Employees. Except as provided by law, for a period of two (2) years after the Closing Date, neither the Stockholder nor any Affiliate thereof shall (a) solicit any person who was an employee of any Company on the date hereof or the Closing Date to terminate his employment with the Buyer (or any Company, as the case may be) or to become an employee of the Stockholder or any Affiliate of the Stockholder, or (b) hire any person who was an employee of any Company on the date hereof or the Closing Date; provided, however, that it shall not be a violation of this Section 8.2 for the Stockholder or any Affiliate thereof (either directly or through another entity) to (y) advertise employment opportunities in newspapers, trade publications or other media not targeted specifically at any such employees of the Buyer or any Company or (z) solicit and/or hire any employee who has ceased to be employed by the Buyer or any Company for a period of at least six months.

8.3 Payment of Outstanding Amounts. To the extent not fully paid at or prior to the Closing as promptly as practicable but not less than 60 days following the Closing Date, the Buyer shall cause the Companies to pay to the Stockholder (or to an Affiliate of the Stockholder designated by the Stockholder) all amounts required to be paid pursuant to Section 5.14 hereof subject to the limitation set forth therein.

8.4 Resale Limitations. From and after the Closing Date until the second anniversary thereof, the Stockholder shall not sell or otherwise dispose of the Buyer Shares in (a) short sales or (b) without the Buyer’s prior written consent, which consent shall not be unreasonably withheld, in trades to a single party exceeding 250,000 Buyer Shares. The provisions of this Section 8.4 shall terminate upon the consummation of a Change in Control of the Buyer. For purposes of this Article VIII, “Change in Control” of the Buyer means any transaction or any event as a result of which (i) any one or more persons or entities, acting as a group, acquires or, for the first time, controls or is able to vote (directly or through nominees or beneficial

ownership), after the Closing Date, 50% or more of the capital stock of the Buyer outstanding at the time ordinarily having power to vote for directors (“Voting Stock”) of the Buyer, provided, however, any acquisition directly from the Buyer shall not constitute a Change in Control, or (ii) the consummation of a merger, consolidation, reorganization or recapitalization involving the Buyer or the disposition of all or substantially all of the assets of the Buyer (a “Business Combination”), unless, immediately following such Business Combination, each of the following two conditions is satisfied: (A) all or substantially all of the persons and entities who beneficially owned the Voting Stock of the Buyer outstanding immediately prior to such Business Combination beneficially own, directly or indirectly, 50% or more of the Voting Stock of the resulting or acquiring corporation outstanding at the time, in substantially the same proportions as their ownership of the Buyer’s Voting Stock outstanding immediately prior to such Business Combination, and (B) no person or entity beneficially owns, directly or indirectly, 50% or more of the outstanding Voting Stock of the resulting or acquiring corporation.

8.5 Standstill Agreement.

(a) From and after the Closing Date until the second anniversary thereof, except with the prior consent of the Buyer Board, the Stockholder shall not, and shall not permit any entity owned or controlled directly or indirectly by him, to: (i) directly or indirectly acquire, announce its intention to acquire, make any proposal to acquire, agree or offer to acquire ownership of any shares of Buyer Common Stock, or any other securities convertible into, or any options, warrants or rights to acquire any shares of Buyer Common Stock or any assets of Buyer (other than property acquired in the ordinary course of business) from the Buyer or any other person or entity; (ii) “solicit” or propose to “solicit” or participate in any “solicitation” of any, “proxy” (as such term is defined in Regulation 14A under the Exchange Act) from any holder of shares of Buyer Common Stock, become a “participant” in a “solicitation” in opposition to any matter that has been recommended by a majority of the members of the Buyer Board, propose or otherwise solicit stockholders of Buyer for approval of any stockholder proposal, or otherwise seek to influence or control the management or policies of Buyer in his capacity as a stockholder of the Buyer; (iii) nominate for election as a director of the Buyer, or vote his Buyer Shares for election as a director of the Buyer, any person who is not nominated by the then incumbent directors of the Buyer; (iv) vote his Buyer Shares against any proposal or matter recommended by a majority of the members of the Buyer Board for approval by the stockholders of the Buyer; (v) take any action to form, join in or in any way participate in any partnership, limited partnership or other Group (as such term is defined under the Exchange Act) with respect to shares of Buyer Common Stock; or (vi) assist or announce his intention to assist any other person or entity in doing any of the foregoing.

(b) The provisions of Section 8.5(a) shall not apply to any actions, determinations or decisions taken or made by the Stockholder, in his capacity as a director of the Buyer and shall terminate upon the consummation of a Change in Control of the Buyer. Nothing contained in this Section 8.5 shall restrict or impede the Stockholder’s ability in carrying out his duties and obligations as a director of the Buyer.

8.6 Nomination of Director. In the event the Stockholder ceases to serve as a director of the Buyer, if the Stockholder nominates an individual (which may include himself) for election as a director of the Buyer (the “Stockholder Nominee”) at any annual meeting of stockholders of the Buyer, the Buyer Board shall (a) nominate the Stockholder Nominee for election to the Buyer Board, and (b) recommend that the Stockholder Nominee be elected to the Buyer Board and such recommendation shall be included in any proxy statement of the Buyer relating to the annual meeting at which the stockholders of the Buyer will consider and act upon such nomination. Notwithstanding the foregoing, the Buyer shall have no obligation under this Section 8.6 unless all of the following conditions are met: (x) the Stockholder Nominee (i) is willing to serve as a Director of the Buyer; (ii) is and has been at all times in compliance with Buyer’s Code of Business Conduct and Ethics; (iii) satisfies the criteria/qualifications for service on the Buyer Board; and (iv) for any Stockholder Nominee other than the Stockholder, is “independent” under the applicable rules of the NASDAQ Global Market; (y) the director nomination complies with the applicable provisions of the Buyer’s Bylaws, as then in effect; and (z) the Stockholder is not in breach of any covenant or agreement of the Stockholder contained in this Agreement or any Related Agreement. The provisions of this Section 8.6 shall terminate upon the consummation of a Change in Control of the Buyer.

8.7 [Intentionally Deleted]

8.8 Employee Matters and Transition Services.

(a) Subject to the provisions of Section 8.8(b) below and without prejudice to Buyer’s right to operate the business of the Companies in the Buyer’s sole discretion after Closing, the Buyer agrees that all persons who are employees of the Companies immediately prior to the Closing (the “Company Employees”) shall (i) continue as employees of the Companies following the Closing on terms and conditions which, in the aggregate, are reasonably comparable to those in effect for similarly situated employees of the applicable Buyer Affiliate in the relevant jurisdiction, and (ii) receive benefits which, in the aggregate, are reasonably comparable to those in effect for similarly situated employees of the applicable Buyer Affiliate in the relevant jurisdiction. To the extent that there is no applicable Buyer Affiliate in the relevant jurisdiction, the Company Employees shall (x) continue as employees of the Companies following the Closing on terms and conditions which, in the aggregate, are reasonably comparable to those currently in effect for such Company Employees, and (y) receive benefits which, in the aggregate, are reasonably comparable to those currently in effect for such Company Employees. Each Company Employee who remains in the employment of any Company following the Closing shall be referred to as a “Continuing Employee.” To the extent permitted by the Buyer Benefit Plans or by amendment of the Buyer Benefit Plans (other than any amendment that would require the approval of the Buyer’s stockholders), the Buyer shall, or shall cause an Affiliate of the Buyer to, recognize and credit each Continuing Employee for the service with any of the Companies (and any predecessor employer to the extent previously credited under the Company Plans) for purposes of participation and vesting under the Buyer Benefit Plans and for purposes of benefit level under vacation and severance plans, but not where giving such credit would result in a duplication of benefits. The Buyer shall use commercially reasonable efforts to cause to be provided to the Continuing Employees credit for any co-payments, deductibles and offsets (or similar payments) made with respect to Company Plans providing medical or dental benefits during the plan year including the Closing Date, for the purposes of satisfying any applicable deductible, out-of-pocket or similar requirements under corresponding Buyer Benefit Plans. Any waiting periods, pre-existing condition exclusions and requirements to show evidence of good health contained in any Buyer Benefit Plans providing medical, dental or other welfare benefits shall be waived with respect to the Continuing Employees and their dependents. Prior to the Closing Date, the Companies shall cooperate with the Buyer so as to allow the Buyer or the applicable Buyer Affiliate to meet with the Continuing Employees (at such times and locations as reasonably agreed to by the Companies and the Buyer), to conduct an open enrollment period to enable the Continuing Employees to make benefit enrollment elections under the Buyer Benefit Plans.

(b) Prior to the Closing Date, MDS and MDS Services shall (i) contribute to the Medisystems Corporation 401(k) Profit Sharing Plan (the “Company 401(k) Plan”) a profit sharing contribution for the 2006 plan year in an aggregate amount not in excess of $165,000, (ii) contribute to the Company 401(k) Plan a pro-rated profit sharing contribution for the 2007 plan year in an aggregate amount not in excess of $165,000, and (iii) take all such actions as may be necessary to cause the Continuing Employees to become fully vested, immediately prior to the Closing Date, in their account balances and accrued benefits under the Company 401(k) Plan.

(c) Prior to the Closing Date, the Stockholder shall take or cause to be taken all necessary action to cause the Companies to cease to be participating employers in the Company Plans listed on Schedule 8.8(c) attached hereto, effective immediately prior to the Closing Date. It is understood that the Continuing Employees will continue under the other benefit plans listed in Section 3.22(a) of the Company Disclosure Schedule at the expense of MDS until December 31, 2007.

(d) Nothing contained in this Agreement shall be interpreted to impose any limits on the authority of Buyer, in its sole discretion, to make any change to the terms or conditions of, or terminate, the employment of any employees of any Companies or to terminate or amend any Buyer Benefit Plan. Section 8.8(a) and 8.8(b) above shall not apply to MDS Italy employees or MDS Mexico employees to the extent such Section would conflict with the requirements of a national collective agreement, individual work contract, applicable law or the current practices of MDS Italy or MDS Mexico.

8.9 Insurance.

(a) At the Closing, the Buyer shall cause the Companies to purchase insurance that will provide for product liability insurance that will survive the Closing for a period of six (6) years after the Closing, covering all products of the Companies manufactured prior to the Closing Date on substantially the same terms and conditions as in effect immediately prior to the Closing.

(b) For a period of six (6) years after the Closing, the Buyer shall cause the Companies to maintain in effect product liability insurance covering all products of the Companies manufactured after the Closing Date on a claims-made basis on substantially the same terms and conditions as in effect as of December 31, 2006.

(c) Buyer agrees that all rights to indemnification now existing in favor of the directors, officers or employees of any of the Companies (including, without limitation, any person who was or becomes a director, officer or employee prior to the Closing Date) under the applicable local law or as provided in each Companies’ Certificate of Incorporation, by-laws or other organizational document with respect to matters occurring on or prior to the Closing shall survive the Closing and shall continue in full force and effect for a period of not less than six (6) years after the Closing (or, in the case of claims or other matters occurring on or prior to the expiration of such six (6) year period which have not been resolved prior to the expiration of such six (6) year period, until such matters are finally resolved) and Buyer shall honor, and shall cause each of the Companies to honor, all such rights. Prior to the Closing, the Stockholder shall cause the Companies to purchase and pay in full a policy of directors’ and officers’ liability insurance and errors and omissions insurance that will survive the Closing for a period of six (6) years after the Closing. Buyer shall not cancel the insurance policy purchased by the Companies pursuant to the immediately preceding sentence.

ARTICLE IX

TAX MATTERS

9.1 Preparation and Filing of Tax Returns; Payment of Taxes.

(a) To the extent not previously prepared and filed, the Stockholder shall prepare and timely file or shall cause to be prepared and timely filed (i) all Tax Returns for any Income Taxes of MDS Services and MDS for all taxable periods that end on or before the Closing Date, and (ii) and cause to be prepared and timely filed all other Tax Returns of any other Company required to be filed (taking into account extensions) prior to the Closing Date. The Stockholder shall make or cause to be made all payments required with respect to any such Tax Returns. The Buyer shall cooperate fully with the Stockholder in connection with the preparation and filing of such Tax Returns. The Stockholder will promptly provide or make available to the Buyer copies of all such Tax Returns.

(b) The Buyer shall prepare and timely file or shall cause to be prepared and timely filed all other Tax Returns for the Companies. The Buyer shall make all payments required with respect to any such Tax Returns; provided, however, that the Stockholder shall promptly reimburse the Buyer to the extent any payment the Buyer is required to make relates to the operations of any Company for any period ending (or deemed pursuant to Section 9.1(d) to end) on or before the Closing.

(c) The Buyer and the Stockholder agree that if any Company is permitted but not required under applicable foreign, state or local Tax laws to treat the Closing Date as the last day of a taxable period, the Buyer and the Stockholder shall treat such day as the last day of a taxable period.

(d) The portion of any Taxes for a taxable period beginning before and ending after the Closing allocable to the portion of such period ending on the Closing Date shall be deemed to equal (i) in the case of Taxes that (x) are based upon or related to income or receipts or (y) imposed in connection with any sale or other transfer or assignment of property, other than Taxes described in Section 9.1(e), the amount which would be payable if the taxable year ended with the Closing Date, and (ii) in the case of other Taxes imposed on a periodic basis (including property Taxes), the amount of such Taxes for the entire period multiplied by a fraction the numerator of which is the number of calendar days in the period ending with the Closing Date and the denominator of which is the number of calendar days in the entire period. For purposes of the

provisions of this Section 9.1(d), each portion of such period shall be deemed to be a taxable period (whether or not it is in fact a taxable period). For purposes of Section 9.1(d)(i)(x), any exemption, deduction, credit or other item that is calculated on an annual basis shall be allocated pro rata per day between the period ending on the Closing Date and the period beginning the day after the Closing Date.

(e) The Stockholder shall be responsible for the payment of any transfer, sales, use, stamp, conveyance, value added, recording, registration, documentary, filing and other non-Income Taxes and administrative fees (including, without limitation, notary fees) arising in connection with the consummation of the transactions contemplated by this Agreement whether levied on the Buyer, the Stockholder, any Company, or any of their respective Affiliates (“Transfer Taxes”). The Base Purchase Price shall be exclusive of any Transfer Taxes.

9.2 Tax Contests; Withholding Taxes; Clearance Certificates and Other Matters.

(a) The Stockholder shall have the right to control, at his own expense, any Tax audit, initiate any claim for refund, contest, resolve and defend against any assessment, notice of deficiency, or other adjustment or proposed adjustment relating to any and all Taxes for any taxable period or portion thereof ending on or prior to the Closing Date with respect to any Company to the extent that the Stockholder may have either (i) a Tax liability (whether as a shareholder of any Company or otherwise) by reason of such assessment, deficiency or adjustment or (ii) an indemnification obligation hereunder with respect; provided, that, the Buyer shall have the right to participate in any Tax proceeding concerning such matters at its own expense directly or through counsel. The Stockholder shall not agree to any settlement of, or entry of any judgment arising from, any such Tax proceeding without the prior written consent of the Buyer, which consent shall not be unreasonably withheld, conditioned or delayed, if any such settlement or entry of judgment would be reasonably expected to increase the Tax liability of the Buyer or of any Company in any taxable period beginning after or including the Closing Date. The Buyer and the Stockholder shall cooperate in the preparation of all Tax Returns and the conduct of all Tax Audits or other administrative or judicial proceedings relating to the determination of any Tax for any Tax periods for which one Party could reasonably require the assistance of the other Party in obtaining any necessary information. Such cooperation shall include, but not be limited to, furnishing prior years’ Tax Returns or return preparation packages to the extent related to the Companies or any Subsidiary illustrating previous reporting practices or containing historical information relevant to the preparation of such Tax Returns, and furnishing such other information within such Party’s possession requested by the Party filing such Tax Returns as is relevant to their preparation. Such cooperation and information also shall include without limitation provision of powers of attorney for the purpose of signing Tax Returns and defending audits and promptly forwarding copies of appropriate notices and forms or other communications received from or sent to any Taxing Authority which relate to the Companies or any Subsidiary, and providing copies of all relevant Tax Returns to the extent related to the Companies or any Subsidiary, together with accompanying schedules and related workpapers, documents relating to rulings or other determinations by any Taxing Authority and records concerning the ownership and Tax basis of property, which the requested Party may possess.

(b) The Buyer shall have the right to control any other Tax audit, initiate any other claim for refund, contest, resolve and defend against any other assessment, notice of deficiency, or other adjustment or proposed adjustment relating to any and all Taxes for any taxable period at its own expense. The Buyer shall not agree to any settlement of, or entry of any judgment arising from, any such Tax proceeding without the prior written consent of the Stockholder, which consent shall not be unreasonably withheld, conditioned or delayed, if any such settlement or entry of judgment would be reasonably expected to increase either (i) the Tax liability of the Stockholder in any taxable period, or (ii) the liability of the Stockholder pursuant to its indemnification obligation hereunder.

(c) Notwithstanding any other provision in this Agreement, the Buyer and each Company shall have the right, on or after the Closing Date, to deduct and withhold Taxes from any payments to be made hereunder if such withholding is required by law and to collect any necessary Tax forms, including Form W-9 or the appropriate series of Form W-8, as applicable, or any similar information, from the Stockholder and any other recipients of payments hereunder. To the extent that amounts are so withheld, such withheld amounts shall be

treated for all purposes of this Agreement as having been delivered and paid to the Stockholder or other recipient of payments in respect of which such deduction and withholding was made.

(d) If, prior to the Closing, the Stockholder shall cause a Company to deliver to Buyer a clearance certificate or similar document(s) which may be required or permitted by any Tax Authority to relieve Buyer of any obligation to withhold Taxes in connection with the Transactions, Buyer shall not withhold any such Taxes.

(e) [Intentionally Deleted]

(f) If required by Mexican Tax law, the Stockholder shall timely pay any capital gains Tax on the transfer of his MDS Mexico equity participation to the Buyer. The Stockholder shall deliver a copy of the corresponding Mexican Tax Return and certified public accountant’s report (dictamen), if any (or documentary evidence, satisfactory to the Buyer, of not being subject to Mexican capital gains Tax), to the Buyer, within the twenty (20) calendar days following the Closing Date, for MDS Mexico to be able to record the Buyer as the new owner of the Stockholder’s equity participation in the Partners’ Registry Book of MDS Mexico without MDS Mexico incurring joint liability with respect to the Stockholder’s Mexican Tax obligations associated with the transfer of such equity participation.

(g) The Parties intend that the Transaction shall constitute a reorganization within the meaning of Section 368(a)(1)(B) of the Code. The Parties adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the U.S. Income Tax Regulations.

ARTICLE X

REGISTRATION RIGHTS

10.1 Piggyback Registrations. Following the Closing Date, if the Buyer proposes to register any Buyer Common Stock under the Securities Act at any time (other than a registration statement relating solely to employee benefit plans or a registration relating to a Rule 145 transaction on Form S-4 or similar forms promulgated in the future) and the registration form to be used may be used for the registration of Buyer Shares, whether or not for sale for Buyer’s own account, the Buyer will give prompt written notice at least 30 days prior to the anticipated effective date of the registration statement relating to such registration (the “Company Registration”) to the Stockholder. The Stockholder may elect, for purposes of such Company Registration only, to have all the rights and obligations of a Holder under Section 2.3 of the Investor Rights Agreement solely with respect to the Buyer Shares held by him, and, to the extent applicable to Section 2.3 thereof only, Sections 2.5, 2.6, 2.7, 2.8, 2.9 and 2.11 of the Investor Rights Agreement; provided, however, that under Section 2.3(a) thereof the underwriters may reduce the number of Buyer Shares to be included in such registration statement to not less than 20% of the total number of Buyer Shares requested to be included in such registration; and, provided, further, that as a condition to the Stockholder’s participation in such Company Registration, the Stockholder must also agree not to sell any shares of Buyer Common Stock held by the Stockholder from the date of the filing of such registration statement until 30 days following the effective date of such registration statement, other than in connection with such Company Registration. For the avoidance of doubt, the Stockholder shall have no rights or obligations in connection with any offering by the Buyer nor shall he have any rights or obligations, as a Holder or otherwise, under the Investor Rights Agreement.

10.2 Assignment of Rights. The Stockholder may not assign any of his rights under this Article X except in connection with the transfer of some or all of the Buyer Shares to a child or spouse, or trust for their benefit, provided each such transferee agrees in a written instrument delivered to the Buyer to be bound by the provisions of this Article X.

10.3 Legends. The Buyer shall be entitled to place appropriate legends on the certificates evidencing the Buyer Shares for purposes of Rule 145 under the Securities Act reflecting the restrictions set forth in Rule 145 and the restrictions imposed by Section 8.4 and to issue appropriate stop transfer instructions to the transfer agent for Buyer Common Stock.

(a) the Stockholder and the Buyer may terminate this Agreement by mutual written consent;

(b) the Buyer may terminate this Agreement by giving written notice to the Stockholder in the event the Stockholder is in breach of any representation, warranty or covenant contained in this Agreement, and such breach (i) individually or in combination with any other such breach, would cause the conditions set forth in clauses (d) or (e) of Section 6.1 not to be satisfied and (ii) is not cured within 20 days following delivery by the Buyer to the Stockholder of written notice of such breach;

(c) the Stockholder may terminate this Agreement by giving written notice to the Buyer in the event the Buyer is in breach of any representation, warranty or covenant contained in this Agreement, and such breach (i) individually or in combination with any other such breach, would cause the conditions set forth in clauses (e) or (f) of Section 6.2 not to be satisfied and (ii) is not cured within 20 days following delivery by the Stockholder to the Buyer of written notice of such breach;
