         5.3.     Noncontravention.    Except as set forth on Schedule 5.3 , neither the execution and delivery of This Agreement and the Ancillary Agreements nor the consummation of the transactions contemplated hereby and thereby by any Medtronic Party will (i) conflict with or result in a breach of or default under the Organizational Documents of such Medtronic Party, (ii) violate any material Legal Requirement to which such Medtronic Party or any of its assets or property is subject or (iii) conflict with or result in a breach of, default under, right to accelerate payment under or obligation to make any payment pursuant to or loss of material rights under, or modify or terminate any material Contractual Obligation (other than the Inter-Party Agreements and the Assumed Contracts to which any Medtronic Party is a party) by which any of the Medtronic Parties or any of their assets or property is bound or subject.

Neither the transactions contemplated by This Agreement nor the payment or other obligations of each of the Medtronic Parties pursuant to This Agreement shall cause such Medtronic Party to be left with unreasonably small capital. The transfer of funds from the Buyer to the Sellers under This Agreement is not on account of any antecedent debt of the Buyer to the Sellers.

        (c)  From the Effective Date until the Closing, if an interference is declared involving any Patent Right included in the Subject Intellectual Property, and notice of such declaration shall have been received by Martin & Ferraro LLP at least six weeks prior to the Closing, the Sellers shall deliver to the Buyer available documents in support of the factual statements necessary to support a preliminary statement as required by 37 C.F.R. §1.622 et seq.

         6.5.     Covenants in Support of Assignment.    To the extent the Sellers cannot transfer and assign any of the Purchased Assets to the Buyer at the Closing for any reason, then the Sellers will, and will cause their Affiliates to, assign and transfer such Purchased Assets to the Buyer at the first opportunity to do so. To the extent that any of the Sellers’ rights, title or interests in any Subject Intellectual Property (including Subject Intellectual Property that the Sellers have rights to under any Assumed Contract) cannot be assigned and transferred by the Sellers to the Buyer, then the Sellers hereby grant to the Buyer and its Affiliates, effective as of the Closing, an irrevocable, perpetual, worldwide, exclusive (even as to the Sellers and subject to the Claims and Encumbrances set forth on Schedule 2.1(a) ) license under such rights, title and interests in any Subject Intellectual Property, with the right to sublicense through multiple tiers, to make, have made, use, sell, offer to sell, import and export products, product systems and processes and to reproduce, distribute, modify, enforce and otherwise exploit such rights, title and interests in any Subject Intellectual Property in any manner for any purpose.

         6.6.     Models and Prototypes.    At the Closing, the Sellers will provide the Buyer with electronic copies of digital photographs of all existing models and prototypes relating to the Subject Intellectual Property, together with whatever indices exist from the Litigation organizing such photographs. The Sellers will not be obligated, however, to deliver the actual three-dimensional models and prototypes to the Buyer. For a period of 25 years following the Effective Date, (i) at the Buyer’s reasonable request, the Sellers shall give the Buyer temporary access upon reasonable notice to such models or prototypes if needed for prosecution of or defense or enforcement of any Subject Intellectual Property and (ii) prior to any of the Sellers destroying or disposing of any such models and prototypes, such Seller will notify the Buyer of his or its intent to destroy or dispose of such prototypes, and if requested by the Buyer, shall either deliver such model or prototype to the Buyer or ensure the Buyer of continued access to such model or prototype.

        (a)  Within 30 days after the creation of any written description or model or prototype of an invention conceived by Michelson included within the definition of Subject Intellectual Property (a “ New Subject Invention ”) and at least 30 days before disclosing the New Subject Invention to any Third Party other than a Representative under an obligation to maintain the confidentiality of such New Subject Invention, the Sellers shall deliver to the Buyer a written description or a model or prototype of the New Subject Invention in sufficient detail to enable a reasonable person of ordinary skill in the Field to understand the nature of the New Subject Invention being disclosed and (if appropriate) to prepare and prosecute one or more patent application(s) (or pursue other protection) with respect to such New Subject Invention. Within 30 days after obtaining or acquiring any new Subject Intellectual Property not conceived by Michelson (“ Acquired Subject Intellectual Property ”), the Sellers shall deliver to the Buyer such Acquired Subject Intellectual Property. The Buyer shall return the originals of any models or prototypes that the Sellers provide to the Buyer as soon as practicable after examining or reproducing such models and prototypes as the Buyer reasonably deems necessary to fully understand the disclosed New Subject Invention or Acquired Subject Intellectual Property, as applicable. In any event, the Buyer shall return such models and prototypes to the Sellers within 30 days after receiving them. Thereafter, at the Buyer’s request, the Sellers will give the Buyer temporary access to such models or prototypes if needed for prosecution

20

of or defense or enforcement of any New Subject Invention or Acquired Subject Intellectual Property. All reasonable out-of-pocket expenses incurred by the Sellers relating to the disclosure of a New Subject Invention or Acquired Subject Intellectual Property, including all conception and reduction to practice of a New Subject Invention or Acquired Subject Intellectual Property will be promptly reimbursed by the Buyer, and in any event within 30 days of receipt of reasonable documentation thereof. No Party shall have any obligation to conceive, acquire, or commercialize Intellectual Property of any kind. Nothing in this Section 6.7 shall limit the obligations of any Party under Section 6.14 (Confidentiality).

        (b)  As security for the performance of the Sellers’ obligation to assign to the Buyer Subject Intellectual Property conceived, acquired or otherwise obtained by Michelson after the Closing during the Term (the “ Secured Obligations ”), the Sellers hereby create a security interest in favor of the Buyer in all of the Sellers’ rights, title and interests in and to Subject Intellectual Property conceived, acquired or otherwise obtained by Michelson after the Closing during the Term (the “ Collateral ”). The Sellers hereby authorize the Buyer, on the Sellers’ behalf, to execute and deliver and file and record in the proper filing and recording places, all such instruments, including Uniform Commercial Code financing statements covering the Collateral, and take all such other actions as the Buyer deems reasonably necessary for perfecting or otherwise confirming its security interest in the Collateral under any applicable Legal Requirement. At the Sellers’ request, the Buyer shall execute and deliver and file and record in the proper filing and recording places, all such instruments, including Uniform Commercial Code termination statements covering any of the Sellers’ assets or properties that is not Collateral, and take all such other actions as the Sellers deem reasonably necessary for terminating or otherwise releasing the Buyer’s security interest in any of the Sellers’ assets or properties that is not Collateral under any applicable Legal Requirement.

         6.8.     Further Assurances.    Following the Closing at the Buyer’s expense, the Sellers shall take such further actions that are reasonably necessary to accomplish the complete transfer and assignment of the Sellers’ rights, title and interests in and to the Purchased Assets to the Buyer, and to assist the Buyer as reasonably necessary with the lawful filing and prosecution of Patent Rights, interferences , and oppositions, and with the Buyer’s determination of whether to continue requests for interferences with respect to the Subject Intellectual Property conceived by Michelson. During the period between the Effective Date and the Closing, the Sellers will notify the Buyer in writing within 10 Business Days after any Seller becomes aware that any interference is declared involving any of the Patent Rights included within the Subject Intellectual Property. Subject to any of the Sellers’ post-Closing obligations under the Assumed Contracts, the Sellers shall not, and shall cause their Affiliates not to, assist any Third Party in the assertion of any Patent Rights In The IP Field (other than the Excluded Intellectual Property) against the Medtronic Parties or their Affiliates, other than under subpoena or other legal process.

         6.9.     Patent Prosecution.    Following the Closing, the Sellers will have no right or obligation to file, prosecute or maintain any Patent Rights included in the Purchased Assets.

         6.10.     Third Party Actions.    Following the Closing and subject to Third Party rights under the Assumed Contracts, the Buyer will have the sole and exclusive right and discretion to enforce the rights, title and interests in and to the Purchased Assets against Third Parties. Following the Closing and subject to Third Party rights under the Assumed Contracts, the Buyer will decide whether or not to institute any proceeding against any Third Party with respect to any alleged infringement or misappropriation of the rights, title and interests in and to the Purchased Assets in its sole and absolute discretion and will keep all proceeds of any such proceedings. If a Medtronic Party is unable to enforce any obligation or other right under an Assumed Contract without a Seller being party to an Action, then Michelson or KTI shall voluntarily join as a party in such Action as necessary to enforce any obligation or other right under an Assumed Contract; provided , that the Buyer agrees in advance to reimburse the Sellers for their reasonable fees, costs and expenses relating thereto. Following the Closing, Michelson shall not testify (whether by declaration, affidavit, or in person) and the Sellers shall not assist any Third Party in challenging the validity, enforceability or value (other than for Tax matters) of the Purchased Assets, in each case other than under subpoena or similar legal order. The Medtronic Parties and their Affiliates shall not assist any Third Party in asserting any Claim or Action relating to the Field (other than for Tax matters) against the Sellers or their Affiliates, other than under subpoena or similar order.

21

6.11.     Patent Counsel; Return of Documents; Tangible Materials.    

        (a)  Based on the facts and circumstances existing as of the Effective Date, each of the Parties consents to any other Party’s engagement of Martin & Ferraro LLP and agree that no conflict of interest exists with respect to Martin & Ferraro LLP’s simultaneous patent prosecution representation of (i) the Medtronic Parties with respect to the Purchased Assets and the Medtronic-Owned Patent Rights and (ii) the Sellers with respect to the Patent Rights in the Excluded Intellectual Property. The Sellers agree that they will have no right to monitor the prosecution of Subject Intellectual Property after the Closing nor any right to have access to any non-public document or file pertaining to such prosecution without the prior consent of the Buyer. Following the Closing, the Sellers shall not initiate consultation with Martin & Ferraro LLP, directly or indirectly, on any prosecution, maintenance or enforcement matter related to the Subject Intellectual Property without the prior consent of the Buyer.

        (b)  The Sellers shall cause Kirkland & Ellis LLP and Jeffer, Mangels, Butler & Marmaro LLP to deliver to the Document Custodian, within 90 days after the Closing, materials received or maintained in their files falling within Paragraph 36 of the Amended Protective Order in the Litigation other than (i) any Litigation materials that are protected by the attorney-client privilege, the work product doctrine or other applicable privileges, or (ii) materials falling within Paragraph 37 of the Amended Protective Order in the Litigation (the “ Protective Order Materials ”). The Parties shall, within 90 days after the Closing, instruct Special Master Balaran to deliver to the Document Custodian the USB 2.0 hard drives and any other media containing the electronic files produced for inspection by the Medtronic Parties during the course of the Litigation (the “ Special Master Materials ”) (the Special Master Materials and the Protective Order Materials are jointly referred to as the “ Litigation Materials ”). The Parties shall instruct the Document Custodian to hold the Litigation Materials until the applicable statute of limitations expires relating to any Claim any of the Medtronic Parties or their respective Affiliates could assert for fraud in the inducement relating to This Agreement, to rescind This Agreement, or for material breach of This Agreement (the “ Retention Period ”), at which time the Document Custodian shall, at the Buyer’s election, either destroy the Litigation Materials or deliver the Litigation Materials to the Buyer. During the Retention Period, the Document Custodian shall grant the Sellers and their Representatives access to such Litigation Materials that the Arbitrator determines is necessary for the Sellers and their Representatives to defend against any Action or Claim initiated by the Buyer or any of its Affiliates against any Seller for fraud in the inducement relating to This Agreement, to rescind This Agreement or for material breach of This Agreement, in which case the Retention Period shall be extended until final resolution of any such Action(s) or Claim(s). Prior to the expiration of the Retention Period, the Buyer may instruct the Document Custodian to either destroy the Litigation Materials or deliver the Litigation Materials to the Buyer if the Buyer delivers to the Sellers an acknowledgement by the Medtronic Parties on behalf of themselves and their respective Affiliates that all applicable statutes of limitation have expired and an unconditional release from the Medtronic Parties and their respective Affiliates of any and all Actions and Claims for fraud in the inducement relating to This Agreement, to rescind This Agreement, and for material breach of This Agreement. Notwithstanding any other provision in This Agreement, the United States District Court for the Western District of Tennessee shall retain exclusive jurisdiction to interpret, modify, or enforce the terms of the Amended Protective Order in the Litigation.

        (c)  Upon reasonable request by the Buyer, the Sellers shall, at the Buyer’s cost and expense, as soon as reasonably practicable deliver an additional copy of any Tangible Materials that are in the possession of any of the Sellers or their Affiliates or Representatives.

         6.12.     Taxes.    The Buyer shall promptly pay all stamp Taxes, conveyance Taxes, transfer Taxes, use Taxes, sales Taxes, filing fees, recording fees, reporting fees and other similar taxes and fees, if any, imposed upon, or resulting from, the transfer of the Purchased Assets under This Agreement and the filing of any instruments relating to such transfer and all filing and recording fees payable to the U.S. Patent and Trademark Office (and similar foreign agencies) in connection with the transfer of the Purchased Assets. In no event shall this Section 6.12 or any other section of This Agreement be construed to impose upon the Buyer or any of its Affiliates the obligation to pay any income Taxes or

22

Taxes other than those transfer Taxes and filing and recording fees specifically described in the preceding sentence of any of the Sellers or any of their Affiliates relating to the transactions contemplated by This Agreement.

         6.13.     Name Attribution.    

        (a)  Beginning 60 days after the Closing and ending upon the expiration of the Term, the Medtronic Parties shall include, or cause to be included, the Michelson Logo (or such other attribution agreed to in writing by the Parties) in all Literature for or referencing an Attribution Product System. During each October and each April during the Term, the Medtronic Parties shall provide Michelson with one original copy of each different item of Literature relating to the Field that any of the Medtronic Parties or their Affiliates, or any Person acting on behalf of any of them, disseminated or made available to a Third Party, or to any member of the sales, marketing, or advertising forces of any of the Medtronic Parties or their Affiliates, during the six previous calendar months (April – September for the October disclosure and October – March for the April disclosure, but the initial period will commence 60 days after the Closing). During the Term, Michelson may from time to time (but no more frequently than twice in any calendar year) provide to the Medtronic Parties a revised list of Attribution Product Systems (a “ Revised Attribution Product System List ”); provided , however , that each of the items on a Revised Attribution Product System List is a product or product system of any of the Medtronic Parties or their Affiliates that practices or includes a feature that is covered by any patent claim of a Patent Right in any of the Purchased Assets, Multi-Lock Patent Rights or Medtronic-Owned Patent Rights. The Medtronic Parties may contest a new item in a Revised Attribution Product System List by providing notice of such contest to Michelson within 30 days after notice of the Revised Attribution Product System List. If Michelson and the Medtronic Parties cannot resolve this issue within 30 days after the Medtronic Parties’ notice that they are contesting the Revised Attribution Product System List, the Parties shall submit the Dispute to arbitration pursuant to Section 10 (Arbitration). A Revised Attribution Product System List becomes controlling as to Attribution Product Systems (A) 60 days after notice of it by Michelson, with respect to items not contested as in the immediately preceding sentence, and (B) within 60 days after resolution of the Parties’ Dispute over an item by arbitration pursuant to Section 10 (Arbitration) or otherwise, with respect to items contested as in the immediately preceding sentence. Notwithstanding anything else in This Agreement, the Medtronic Parties cannot and shall not contest any item in a Revised Attribution Product System List that has previously appeared in Schedule 6.13(a) , as such list is revised from time to time pursuant to Section 6.13(a) or Section 6.13(b).

        (b)  Except for New Product Systems whose Commercial Launch occurred during the period from October 1, 2003 and ending 60 days prior to the Closing, at least 60 days prior to the Commercial Launch of a prospective New Product System the Medtronic Parties shall provide to Michelson a description of each prospective New Product System along with any draft or non-draft Literature to date and reasonably sufficient information, and at the request of Michelson a sample product or product system to examine for a reasonable period, to allow Michelson to review the New Product System and make a determination that it is an Attribution Product System. Upon a determination by the Medtronic Parties or an agreement of the Parties that it is an Attribution Product System, the Medtronic Parties shall, within 10 Business Days thereafter, deliver to Michelson a Revised Attribution Product List reflecting the determination or agreement. The Parties are considering use of Martin & Ferraro LLP as a neutral initial reviewing party. If Michelson provides notice within 30 days after receipt of the description and Literature referred to in the first sentence of this Section 6.13(b), that the New Product System is an Attribution Product System and if the Medtronic Parties disagree and this Dispute is not resolved within 30 days after Michelson’s notice, or such other time frame that the Parties may agree in writing, the Parties shall submit the Dispute to arbitration pursuant to Section 10 (Arbitration) and the Medtronic Parties shall not be required to provide attribution on Literature relating to such New Product System unless and until a final determination by the Arbitrator with regard to that Dispute. The Parties acknowledge and agree that a New Product System will not require attribution under This Agreement until the Commercial Launch of such new or modified product or product system.

23

        (c)  The Medtronic Parties shall ensure that the Michelson Logo (or such other attribution agreed to in writing by the Parties) appears, in the expression specified opposite the applicable category of Literature in Schedule 6.13(c), on each item of Literature for or referencing an Attribution Product System. The Medtronic Parties or their Affiliates may also use a symbol, logo or trademark of the Medtronic Parties or their Affiliates or any other lawful means as an indication of origin for any Attribution Product System. The Medtronic Parties acknowledge that the damages from a failure of any of them or their Affiliates to comply with the provisions of Section 6.13 are difficult to calculate. Therefore, to avoid the difficulty and inconvenience of gathering the information necessary to calculate the damages resulting from such a failure to comply, and to avoid future disputes about the amount of such damages, the Parties agree that (except with respect to the power to issue an order with respect to any New Product System set forth in Section 6.13(b)), Michelson’s sole and exclusive remedy for any such failure to comply with the provisions of Section 6.13 will be liquidated damages (which are not, will not be characterized by the Parties as, and will not be deemed to be a penalty) in the amount and nature specified opposite the applicable category of Literature in Schedule 6.13(c) . No liquidated damages will be due with respect to any Literature where (i) an identical copy of it was sent to Michelson before its dissemination with a request for a decision from Michelson as to whether the attribution or lack thereof is appropriate and to which Michelson did not raise an objection within 15 days or (ii) such Literature did not include a trade, product, product system or company name used by any of the Medtronic Parties or their Affiliates or any Person claiming rights as a result of a Third Party Attribution Transfer. In all instances, the Medtronic Parties shall use commercially reasonable efforts to make sure that the Michelson Logo is visible, unobstructed, not obscured, and fairly rendered.

        (d)  Notwithstanding the exception in (iii) of the definition of Literature, neither the Medtronic Parties nor their Affiliates shall publish materials through a Third Party in order to attempt to avoid the obligations of Section 6.13. If any of the Medtronic Parties or their Affiliates provides materials or consideration to a Third Party publisher for use in a Third Party publication pursuant to a written agreement or understanding regarding the use of such materials, then the Medtronic Parties shall (i) ensure that any materials provided to such Third Party by Medtronic have the appropriate attribution as required by This Agreement and (ii) request in any such agreement or understanding that the Third Party include the attribution as appropriate under This Agreement. Medtronic shall use commercially reasonable efforts to ensure that Third Party publishers who acknowledge contributions from Medtronic also provide appropriate attribution as required by This Agreement in published articles and papers. Medtronic shall have no affirmative obligation to enforce or ensure that such Third Party actually includes the Michelson Logo pursuant to Section 6.13(d)(ii) hereof and shall have no liability to Michelson under Section 6.13(d)(ii) for any act or omission of a Third Party.

        (e)  The definition of “Literature” and the exclusions included in such definition are intended to encompass all currently known forms of promotional or educational materials disseminated or made available to Third Parties by any of the Medtronic Parties or their Affiliates. In the event a new form of dissemination of promotional or educational materials is developed during the Term upon notice by any of the Parties, the Parties shall meet and confer within 30 days thereafter as to (i) whether such materials are of such a nature that they should be excluded based on similar rationale to the exclusions in the definition of Literature, and (ii) if not, the appropriate expression and mode of liquidated damages to be assessed in the future. If the Parties are not able to come to terms during such 30-day period, then the Parties shall submit the Dispute to arbitration pursuant to Section 10 (Arbitration). In the event that the Arbitrator makes a final determination that the type of dissemination is to be treated as Literature in the future, the Arbitrator shall decide upon an appropriate expression of name attribution and liquidated damages and injunctive relief associated therewith.

        (f)  Any materials distributed by the Medtronic Parties or their Affiliates prior to 60 days after the Closing will not be subject to liquidated damages or injunctive relief pursuant to This Agreement or otherwise. Notwithstanding the immediately preceding sentence, the Medtronic Parties shall use good faith and reasonable commercial efforts to (i) cease dissemination of non-conforming

24

Literature after the Closing, and (ii) conform existing materials in Medtronic’s central inventory in Memphis between the Effective Date and 60 days after the Closing. Notwithstanding anything else in This Agreement, the Medtronic Parties shall not be liable for liquidated damages for errors in conforming existing materials in Medtronic’s central inventory in Memphis at the Closing that had appropriate attribution pursuant to the court’s order in the Litigation and are distributed within 180 days after the Closing.

        (g)  The Medtronic Parties shall conspicuously display, or cause to be conspicuously displayed, the Michelson Logo (or such other attribution agreed to in writing by the Parties) in connection with any displays to Third Parties of the Tangible Materials that are part of the Purchased Assets identified in Section 2.1(e).

        (h)  In any Third Party Attribution Transfer, the Person granting the Third Party Attribution Transfer shall require any Third Party receiving the benefit of the Third Party Attribution Transfer to agree, in a written Contractual Obligation against the Third Party, to provide name attribution on a basis no less stringent, including at least all rights, obligations, and liquidated damages under Section 6.13, than if a Medtronic Party was providing any product, service, or Literature provided by or on behalf of the Third Party or on behalf of any Person with rights through the Third Party, with the writing memorializing the Contractual Obligation expressly identifying Michelson as a third-party beneficiary of the name attribution obligations with an independent right of enforcement without the need to join any other Person. The immediately preceding sentence does not apply to the current term of any Assumed Contract that is not amended after the Effective Date. If Michelson is unable to enforce any name attribution obligations under an Assumed Contract without a Medtronic Party being part of an Action, then such Medtronic Party or an Affiliate of such Medtronic Party shall voluntarily join or otherwise participate in an Action as necessary to enforce the name attribution obligations of Third Parties; provided , that Michelson agrees in advance to reimburse such Medtronic Party for its reasonable fees, costs and expenses relating thereto. None of the Medtronic Parties shall have any affirmative obligation to enforce or ensure that such Third Party actually includes the Michelson Logo pursuant to any Contractual Obligation or otherwise, and none of the Medtronic Parties shall have any liability to Michelson for any act or omission of a Third Party. Notwithstanding anything else in This Agreement, the Person granting the Third Party Attribution Transfer shall have (i) the right to agree with the Third Party in good faith to determine which products and product systems require attribution under any Third Party Attribution Transfer, which will be at least the products and product systems that practice or include a feature that is covered by an issued and unexpired patent claim of a Patent Right in the Purchased Assets, Multi-Lock Patent Rights or Medtronic-Owned Patent Rights and (ii) the right to grant one Third Party Attribution Transfer as part of a transaction that involves multiple business segments of MDT without requiring any attribution as provided in This Agreement.

        (i)  The Medtronic Parties and their Affiliates shall use commercially reasonable efforts to ensure that all product systems with which they use the Michelson Logo (i) meet or exceed the Medtronic Parties’ current standards of quality and performance relating to similar products, with which the Sellers are generally familiar, and standards of quality and performance generally accepted in the industry, (ii) meet or exceed standards of quality and performance of any applicable governmental agency, and (iii) comply with all applicable laws, rules, and regulations. The Sellers’ sole and exclusive remedy for any failure of the Medtronic Parties and their Affiliates to comply with the immediately preceding sentence is that Michelson may require that the name attribution under this Section 6.13 not be made on any product system (and such product system is deemed removed from the then-current list of Attribution Product Systems), and in response the Medtronic Parties and their Affiliates shall comply with the requirement within 60 days on a rolling basis. Once a product or product system is removed from the list of Attribution Product Systems, it cannot be replaced without the express, written consent of the Medtronic Parties.

        (j)  Michelson may revise the Michelson Logo, temporarily or permanently, and with respect to some or all uses required or permitted under This Agreement, in response to any Claim that a use

25

of the Michelson Logo as required or permitted under This Agreement violates a Legal Requirement. If Michelson so revises the Michelson Logo, or requests that the Michelson Logo or other attribution not be used in a way required or permitted by This Agreement, the Medtronic Parties shall use the new Michelson Logo or comply with the request as promptly as commercially practicable. The cessation of attribution or change of Michelson Logo may, for 30 days, be accomplished through the use of stickers where possible, unless Michelson determines in his reasonable discretion that such use of stickers would not avoid liability based upon the asserted Legal Requirement.

        (k)  Any disclosures by any of the Medtronic Parties or their Affiliates pursuant to this Section 6.13 shall be deemed to be Confidential Information of the Medtronic Parties.

        (l)  In the event any of the Medtronic Parties or their Affiliates conduct or sponsor an IDE clinical study or other study that involves Subject Intellectual Property or Medtronic-Owned Patent Rights or MultiLock Patent Rights, such Medtronic Party or Medtronic Party Affiliate shall include within the materials sent to clinical sites a stand-alone notification describing Michelson’s intellectual property contributions with a request that such clinical sites include a reference to Michelson’s intellectual property contributions in any press releases, articles or other public information when referring to such studies.

        (m)  The rights and obligations of the Parties pursuant to this Section 6.13 shall terminate upon expiration of the Term; provided , that (i) the rights and obligations of the Parties pursuant to Section 6.13(k) shall survive the expiration of the Term and (ii) the Sellers’ rights to pursue Third Parties or to pursue liquidated damages remedies set forth in this Section 6.13 for any breach by the Medtronic Parties or their Affiliates occurring during the Term shall survive the expiration of the Term.

         6.14.     Confidentiality.    Each of the Parties acknowledges that the preservation of the confidentiality of the Confidential Information of the other Parties is an essential premise of the bargain between the Parties and that the Parties would be unwilling to enter into This Agreement in the absence of this Section 6.14. Accordingly, from and after the Closing, except as otherwise contemplated by This Agreement, each Party (the “ Bound Party ”) shall not, and shall cause its Affiliates and Representatives not to, without the prior written consent of the other Parties to whom the Confidential Information belongs (the “ Other Parties ”), disclose the Confidential Information of the Other Parties to any Person other than the Bound Party’s Representatives who are informed of and bound by this confidentiality obligation or use the Confidential Information; provided , that this Section 6.14 does not prohibit any disclosure (a) reasonably believed by the Bound Party to be required by any applicable Legal Requirement, provided that the Bound Party provides reasonable prior notice of the disclosure to the Other Parties to allow such Other Parties, if they desire, to contest the disclosure before it is made, (b) to Third Parties who are parties to any of the Assumed Contracts, to the extent reasonably necessary with respect to the Bound Party’s rights or obligations under the Assumed Contracts, including informing the Third Parties that the Assumed Contracts have been assigned and assumed, or (c) made in furtherance of the enforcement or interpretation of any rights, remedy, or provision in, relating to or arising under This Agreement, the Ancillary Agreements or the transactions contemplated in This Agreement or the Ancillary Agreements.

         6.15.     Restricted Activities.    As a material inducement to the Buyer’s purchase of the Purchased Assets under This Agreement, including goodwill, each of the Sellers hereby covenants and agrees that from and after the Closing until the expiration of the Term, none of the Sellers will, either directly or indirectly, (a) engage in, or (b) own, manage, operate, control, be employed by, consult with, or assist, any Third Party or any Affiliate of any Seller engaged in, the practice, development, production, manufacture, sale, licensing, sublicensing or servicing of products, techniques or procedures in the Field in any geographic area in which the Buyer or any of its Affiliates conducts any business in the Field (collectively, the “ Restricted Field ”); provided , that this Section 6.15 does not prohibit (i) ownership of less than 10% of the outstanding stock of any publicly traded corporation or less than 20% of the equity interest of any hospital, medical clinic or center, or other provider of medical services, (ii) participating

in speaking engagements at, writing textbooks, treatises or articles for, or teaching at colleges, universities, hospitals, charitable organizations or trade or industry conferences, or the like, including with respect to devices or methods that are the subject of the Restricted Field, (iii) practicing medicine as a licensed physician or surgeon, including the use of devices or methods that are the subject of the Restricted Field as part of such practice, (iv) performance under consulting agreements set forth on Schedule 6.15 , as such agreements are in effect on the Effective Date, (v) licensing or assigning the Excluded Intellectual Property, (vi) other commercial exploitation of the Excluded Intellectual Property so long as such other commercial exploitation does not infringe or misappropriate any Purchased Assets, (vii) serving on any boards of directors of any not-for-profit organizations or any other similar charitable foundations, (viii) serving as an officer of any not-for-profit organizations or any other similar charitable foundations so long as the activities or the results of the activities of such organizations or foundations are not directed to the Field other than solely due to their general application to the human body, (ix) making unrestricted gifts of cash, securities or other property to not-for-profit organizations or any other similar charitable foundations that are not Affiliates of Michelson, including those engaged in research in the Field, (x) making gifts of cash, securities or other property to not-for-profit organizations or any other similar charitable foundations so long as the activities or the results of the activities of such organizations or foundations are not directed to the Field other than solely due to their general application to the human body or (xi) consulting with or assisting any Third Party or any Affiliate of any Seller in the Field solely with respect to the Excluded Intellectual Property or consulting with or assisting any Third Party or any Affiliate of any Seller outside the Field. The Sellers agree that the covenants of this Section 6.15 are reasonable and valid. If the final judgment of a court of competent jurisdiction declares that any term or provision of this Section 6.15 is invalid or unenforceable, the Parties agree that the court making the determination of invalidity or unenforceability will have the power to reduce the scope, duration or area of the term or provision, to delete specific words or phrases or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and This Agreement will be enforceable as so modified after the expiration of the time within which the judgment may be appealed.

         6.16.     Use of Michelson Logo.    The Sellers shall not, and shall not permit any Affiliate or Third Party to, use the Michelson Logo (or any other logo confusingly similar thereto) in connection with any products other than products in the medical field that use or incorporate ideas conceived or developed by Michelson. All goodwill associated with use of the Michelson Logo shall inure to the benefit of Michelson.

         6.17.     Notice of Developments.    From the Effective Date until the Closing, the Sellers will give the Buyer prompt written notice upon becoming aware of any material development affecting the Purchased Assets and Excluded Intellectual Property (including claim amendments since March 7, 2005) or any event or circumstance that could reasonably be expected to result in a material breach of, or inaccuracy in, any of the Sellers’ representations and warranties; provided , that no such disclosure will be deemed to prevent or cure any such breach of, or inaccuracy in, amend or supplement any Schedule to, or otherwise disclose any exception to, any of the representations and warranties set forth in This Agreement, unless, notwithstanding such disclosure, the Buyer consummates the Closing, in which case each such disclosed breach of, or inaccuracy in, the Sellers’ representations and warranties shall be deemed waived by the Buyer and shall not be a source of Losses for which the Sellers provide indemnification pursuant to Section 9 (Indemnification).

         6.18.     Corporate Existence.    For a period of two years following the Closing, KTI shall not dissolve or liquidate.

         6.19.     Revival and Reinstatement of Payment Obligations.    If any payment by the Buyer to the Sellers under This Agreement, in whole or in part, should for any reason subsequently be declared to be void or voidable under any state or federal law relating to creditors’ rights, including provisions of the Bankruptcy Code relating to fraudulent transfers, preferences, or other voidable or recoverable payments of money or transfers of property (collectively, a “ Voidable Transfer ”), and if the Sellers are required to repay or restore, in whole or in part, any such Voidable Transfer, or elect to do so upon the reasonable advice of their counsel, then, to the extent of the amount of such Voidable Transfer that the

27

Sellers are required or elect to repay or restore, and as to reasonable costs, expenses, and attorneys’ fees of the Sellers incurred with respect thereto, the liability of the Buyer to the Sellers automatically shall be revived, reinstated, and restored and shall exist as though such Voidable Transfer had never been made.

         6.20.     Public Statements.    None of the Parties shall make any public statement, whether in a press release, interview, article, book, press conference, speaking engagement, or otherwise, relating to the terms of This Agreement or the Ancillary Agreements or the details of the discussions and drafts leading up to the execution of This Agreement and the Ancillary Agreements (each, a “ Public Statement ”) without the prior consent of the other Parties, which consent shall not be unreasonably withheld; provided , that any Party may make such Public Statement it believes in good faith is required by applicable Legal Requirements or the requirements of any national securities exchange or quotation system on which such Party’s securities are listed or quoted for trading, in which case the disclosing Party will provide the other Parties with the reasonable opportunity to review in advance such Public Statement, where practicable; provided , further , in the event that any Party makes a Public Statement in accordance with this Section 6.20, any Party may repeat any of the information set forth in such Public Statement.

         9.4.     Time for Claims.    No Claim may be made seeking indemnification pursuant to This Agreement unless a written notice thereof is provided to the Indemnifying Party (i) at any time before the expiration of the applicable survival period set forth in Section 9.3 (Survival), in the case of any breach of any of the representations or warranties in This Agreement, and (ii) at any time, in the case of any other Claim seeking indemnification pursuant to This Agreement.

         9.5.     Notices.    If an Indemnified Party intends to seek indemnification pursuant to This Agreement, such Indemnified Party shall promptly notify the Indemnifying Party in writing of the Claim for which indemnification is sought, including any Third Party Claims in respect of which indemnification is sought under This Agreement, in each case within the applicable time periods specified in Section 9.4 (Time for Claims).

Any delay in the provision of such notice and accompanying materials shall not affect any rights under This Agreement except to the extent that the Indemnifying Party is actually and materially prejudiced thereby.

         9.6.     Third Party Claims.    The Indemnifying Party will be entitled to participate in the defense of any Third Party Claim that is the subject of a notice given by the Indemnified Party pursuant to Section 9.5 (Notices). In addition, the Indemnifying Party will have the right to defend the Indemnified Party against the Third Party Claim with counsel of the Indemnifying Party’s choice reasonably satisfactory to the Indemnified Party so long as:

        (a)  the Indemnifying Party gives written notice to the Indemnified Party within 10 Business Days after the Indemnified Party has given notice of the Third Party Claim that the Indemnifying Party will indemnify the Indemnified Party against the entirety of any and all Losses the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of or caused by the Third Party Claim;

        (b)  the Third Party Claim involves only money damages and does not seek an injunction or other equitable relief against the Indemnified Party;

        (d)  the Third Party Claim does not relate to or otherwise arise in connection with any criminal or regulatory enforcement Action; and

        (e)  the Indemnifying Party conducts the defense of the Third Party Claim actively and diligently.

        If any of the foregoing conditions is not satisfied, the Indemnified Party may assume control of the defense of the Third Party Claim with counsel of its choice and the Indemnified Party’s reasonable legal fees and expenses shall constitute part of the Losses indemnified under This Agreement, provided, that such Claim for indemnification is agreed by the Indemnifying Party or otherwise determined in the Indemnified Party’s favor by the Arbitrator. The Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim; provided , that the Indemnifying Party will pay the fees and expenses of separate

34

co-counsel retained by the Indemnified Party that are incurred prior to Indemnifying Party’s assumption of control of the defense of the Third Party Claim. The Indemnifying Party will not consent to the entry of any judgment or enter into any compromise or settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party unless such judgment, compromise or settlement (i) provides for the payment by the Indemnifying Party of money as sole relief for the claimant, (ii) results in the full and general release of the Indemnified Party from all Liabilities arising or relating to, or in connection with, the Third Party Claim and (iii) involves no finding or admission of any violation of Legal Requirements or the rights of any Person and no effect on any other Claims that may be made against the Indemnified Party. If the Indemnifying Party does not deliver the notice contemplated hereby within 10 Business Days after the Indemnified Party has given notice of the Third Party Claim, or otherwise at any time fails to conduct the defense of the Third Party Claim actively and diligently, the Indemnified Party may defend, and may consent to the entry of any judgment or enter into any compromise or settlement with respect to, the Third Party Claim in any manner it may deem appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith). If the Indemnifying Party is entitled to assume control of the defense of the Third Party Claim hereunder, and conducts the defense of the Third Party Claim actively and diligently but any of the other conditions set forth in clauses (a) through (e) of this Section 9.6 is or becomes unsatisfied, the Indemnified Party may defend, and may consent to the entry of any judgment or enter into any compromise or settlement with respect to, the Third Party Claim; provided , that the Indemnifying Party will not be bound by the entry of any such judgment consented to, or any such compromise or settlement effected, without its prior written consent (which consent will not be unreasonably withheld or delayed). Notwithstanding anything to the contrary in This Agreement, in the event that a Third Party Claim is asserted against one or more Medtronic Indemnified Parties and the potential for indemnification arises from or relates to an actual or alleged breach of the Sellers’ representations and warranties set forth in Section 4.8(d)(i) of This Agreement, then the response to and defense of such Claim shall be managed as follows. The Medtronic Indemnified Parties will have the sole and exclusive right to defend, settle or agree to entry of judgment of such Third Party Claim with counsel of its choice. However, any such judgment, settlement or finding by any court or arbitral body shall not be dispositive or admissible evidence with respect to determining whether the Sellers have breached any of their representations or warranties in Section 4.8(d)(i) of This Agreement.

         9.7.     LIMITATION OF DAMAGES.    THE PARTIES SHALL ONLY BE LIABLE FOR ACTUAL DAMAGES (INCLUDING DIMINUTION OF VALUE OF THE PURCHASED ASSETS) AND SHALL NOT BE LIABLE FOR INDIRECT, SPECIAL, INCIDENTAL OR PUNITIVE DAMAGES OF ANY KIND RELATING TO OR ARISING OUT OF THIS AGREEMENT OR THE ANCILLARY AGREEMENTS, WHETHER OR NOT SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THE LIMITATION SET FORTH IN THIS SECTION SHALL NOT APPLY TO CLAIMS FOR AMOUNTS PAID WITH RESPECT TO INDEMNIFICATION FOR LOSSES ARISING FROM THIRD PARTY CLAIMS.

         9.8.     Exclusive Remedy.    Except as expressly stated otherwise in This Agreement, the indemnities set forth in this Section 9 shall be the exclusive remedy for any Claims, whether Third Party Claims or direct Claims between the Parties, relating to or arising out of This Agreement, the Ancillary Agreements or the transactions contemplated hereby or thereby.

         9.9.     Knowledge and Investigation.    Except as expressly set forth in the proviso to Section 6.17 (Notice of Developments), the right of any Indemnified Party to indemnification pursuant to this Section 9 will not be affected by any investigation conducted or knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of This Agreement or the Closing, with respect to the accuracy of any representation or warranty, or performance of or compliance with any covenant or agreement under This Agreement.

         9.10.     Letter of Credit.    For as long as any amounts are outstanding under the Closing Letter of Credit or any Post-Closing Letter of Credit (collectively, the “ LOCs ”), or Escrow Account, as applicable, any and all amounts payable by the Sellers as Indemnifying Parties to a Medtronic Indemnified

35

Party shall be paid in cash first out of the LOCs or the Escrow Account, as applicable, and thereafter by the Sellers in accordance with payment instructions provided by the Buyer. The existence of the LOCs or the Escrow Account, as applicable, shall not be deemed to limit the amount of any allowable Claims by any Medtronic Indemnified Party pursuant to This Agreement for Losses in excess of the outstanding amounts under the LOCs or the Escrow Account, as applicable. The Sellers shall cause the principal amounts under each of the LOCs or the Escrow Account, as applicable, to remain outstanding until the earlier of (a) such time as the entire principal amount of such LOC or the Escrow Account, as applicable, has been used to pay the Medtronic Indemnified Parties in accordance with a decision of the Arbitrator and (b) the fifth anniversary of the Closing and thereafter the funds in the Escrow Account shall be released to the Sellers or the LOCs shall be terminated, as the case may be; provided , that if any Claim seeking indemnification has been timely made in accordance with Section 9.4 (Time for Claims) but has not been finally determined by the Arbitrator by the fifth anniversary of the Closing, then the Sellers shall cause the principal amounts under each of the LOCs or the Escrow Account, as applicable, to remain outstanding until such final determination of each such Claim in an aggregate principal amount sufficient to satisfy the aggregate amount of Losses to which the Medtronic Indemnified Parties reasonably estimate (and provide the Sellers prior notice of) they may be entitled to recover from the Sellers in respect of all such Claims.

         9.11.     Duty to Mitigate.    The Parties acknowledge that in determining the amount of any Loss to which any Indemnified Party is entitled to indemnification under this Section 9, the Arbitrator shall take into account the degree to which such Indemnified Party took or failed to take action to mitigate such Loss.

         10.1.     Agreement to Arbitrate.    To expedite the resolution of Disputes that may arise between the Parties, the Parties, on behalf of themselves and their respective Affiliates, agree that any and all Disputes shall be submitted to final and binding arbitration pursuant to the procedures set forth in this Section 10. The Parties consent to the exclusive jurisdiction of the Arbitrator to finally resolve any and all Disputes, including a Dispute under Section 8.1(f), and waive any and all resort to any court in connection with any and all Disputes, regardless of the legal or equitable theory upon which such Disputes may be based, except for the enforcement, vacation or remand of any arbitration award or arbitration order. Any dispute concerning whether any Dispute is arbitrable pursuant to This Agreement shall be resolved by the Arbitrator and not by any court.

         10.2.     Appointment and Replacement of Arbitrator.    MSD, on behalf of the Medtronic Parties, and the Sellers shall appoint an arbitrator pursuant to the provisions of this Section 10.2 promptly after the execution of This Agreement. That arbitrator or a replacement selected pursuant to this Section 10.2 (in either case, the “ Arbitrator ”) shall be retained by the Medtronic Parties and the Sellers as the Arbitrator for the Term. The Arbitrator shall be appointed according to the following procedure: the Sellers shall provide to the Medtronic Parties a list of ten individuals (“ Potential Arbitrators ”) who are all able and willing to fulfill the duties of the Arbitrator under this Section 10, who have not previously represented any of the Parties or their Affiliates, and who are either (i) former judges of a United States District Court or a United States Court of Appeals, or (ii) intellectual property attorneys with at least 20 years of experience in intellectual property litigation. Of the Potential Arbitrators, the Sellers will provide at least four suggestions from each category. MSD, on behalf of the Medtronic Parties, shall then have 30 days to select one name from the list of Potential Arbitrators and inform the Sellers of the selection. If the Medtronic Parties fail or refuse to select one name from the list of Potential Arbitrators, the Sellers shall have the power to select the Arbitrator from the list of Potential Arbitrators. Should the Arbitrator (including any replacement) at any time be unable or unwilling to fulfill his or her duties, or be disqualified pursuant to Section 10.13, the Parties will appoint a replacement (who will then be the “Arbitrator”) following this same procedure.

         10.3.     Exclusive Dispute Resolution Procedure.    The arbitration procedure contained in this Section 10 shall be the exclusive dispute resolution procedure available to the Parties with respect to any and all Disputes.

In addition, the Arbitrator shall have the power to execute and deliver and file and record in the proper filing and recording places, all such instruments, including Uniform Commercial Code termination statements covering or purporting to cover any of the Sellers’ assets or properties that is not Collateral, and take all such other actions as the Arbitrator shall determine to be appropriate to terminate or otherwise release the Buyer’s security interest in any of the Sellers’ assets or properties that the Arbitrator determines is not Collateral under any applicable Legal Requirement. The Arbitrator shall award to the prevailing Arbitration Party or Arbitration Parties its or their reasonable attorneys’ fees and costs. For purposes of determining which Arbitration Party is the prevailing party and thus entitled to recover attorneys’ fees and costs, the Arbitrator must do so in the following manner. The Arbitrator shall determine which Arbitration Party’s Arbitration Settlement Offer is closer to the Arbitrator’s final award and shall determine that such Arbitration Party is the prevailing party for purposes of awarding reasonable attorneys’ fees and costs.

        (b)  The Arbitrator’s awards shall be accompanied by detailed findings of fact and conclusions of law, final and binding upon, and enforceable as to, the Parties. The Arbitrator’s final award shall be rendered no later than 30 days after the close of the Hearing.

        (c)  The award rendered by the Arbitrator shall be collateral estoppel as to any issue found against a Party in any later arbitration.

Each Party

38

further agrees that, in the event of any such entry of an interim award in any court of the United States or any state thereof having jurisdiction over the Parties and the matters, no Party will assert that a remedy at law would be adequate as a defense to enforcement of the Arbitrator’s previously issued interim award for specific performance.

         10.12.     Arbitrator’s Fees.    The Arbitrator shall be paid an annual retainer of $50,000. The Arbitrator shall be entitled to additional compensation for services rendered and costs incurred in connection with any arbitration proceeding, as specified by the Arbitrator.

         10.13.     Impartiality and Disqualification of Arbitrator; Ex Parte Contacts.    

        (a)  The Arbitrator shall be subject to disqualification if his or her impartiality or independence can reasonably be questioned, and shall be obligated to disclose to the Parties any circumstance likely to give rise to a reasonable doubt as to his or her impartiality or independence, including the acquisition of any financial interest in any of the Parties or their Affiliates. Any request for disqualification of the Arbitrator shall be made to the Arbitrator, who shall consider the request from the perspective of a reasonable observer who is informed of all the surrounding facts and circumstances, and if the Arbitrator determines that the impartiality or independence of the Arbitrator can reasonably be questioned, then (i) the Arbitrator shall no longer serve as Arbitrator of any Dispute that may arise between the Parties, including any pending Dispute and (ii) the Parties will select a new Arbitrator, as necessary, pursuant to Section 10.2 (Appointment and Replacement of Arbitrator). Upon the request of either party, the determination contemplated by this Section 10.13(a) can be submitted to a second arbitrator chosen in accordance with Section 10.2 (Appointment and Replacement of Arbitrator). In the event the second arbitrator determines that the impartiality or independence of the Arbitrator can reasonably be questioned, then the Parties will select a new Arbitrator, as necessary, pursuant to Section 10.2 (Appointment and Replacement of Arbitrator) from a list that shall not include the second arbitrator who made the determination. If the Arbitrator makes a determination that the impartiality or independence of the Arbitrator cannot reasonably be questioned, then the Arbitrator shall remain engaged as provided in This Agreement.

        (b)  No Party or its Representative shall, unless the Parties agree, or if there is an arbitration proceeding pending, unless all of the parties to the arbitration proceeding agree, communicate ex parte with the Arbitrator, except that the Arbitrator may conduct any communication or proceeding on an ex parte basis if the Arbitrator determines that the non-appearing Party or Parties received reasonable advance notice thereof and did not provide reasonable justification for their failure to appear, or if the Arbitrator, upon notice to all Parties, deems such communication necessary.
