Notwithstanding the foregoing provisions of this Section 6.4(a), no Company employees shall have the right to participate in the Thoratec Corporation 401(k) Plan at any time after the Closing.

(b) Except as otherwise provided in this Section 6.4 or in the Transition Services Agreement, as of January 1, 2011, the Seller and the Company shall take such action as is necessary such that the Company shall cease being a “participating employer” and shall cease any co-sponsorship and participation in each Benefit Plan that is not a Company Benefit Plan (each such Benefit Plan being a “Seller Plan”). The Company shall have no further Liability and the Seller shall retain all Liabilities for Claims incurred under any Seller Plan (as determined under the terms of the Seller Plans), whether such Claims are incurred prior to, on or after the Closing Date. Seller shall provide under the Seller Plans any continuation coverage required under Section 4980B of the Code, Part 6 of Title I of ERISA or applicable state Law

(“COBRA”) to each “qualified beneficiary” as that term is defined in COBRA whose first “qualifying event” (as defined in COBRA) occurs on or prior to the Transition Service Expiration Date.

(c) With respect to each employee benefit plan of Buyer or any Subsidiary thereof (each a “Buyer Plan”), in which Company employees subsequently participate, for purposes of determining vesting and entitlement to benefits, including for severance benefits and vacation entitlement, service with the Company (or predecessor employers thereof) shall be treated as service with the Person providing such Buyer Plan to the extent such service was taken into account under any substantially similar plan in which any such Company employee participated immediately prior to the Transition Service Expiration Date; provided, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits. To the extent permitted by each Buyer Plan, such Buyer Plan shall waive pre-existing condition limitations and waiting periods with respect to participation and coverage requirements to the same extent such limitations or waiting periods were inapplicable to, or had been satisfied by, such Company employee immediately prior to the Transition Service Expiration Date under the analogous Benefit Plan in which such Company employee participated. To the extent permitted by each Buyer Plan, Company employees shall be given credit for amounts paid under a corresponding Benefit Plan during the plan year in which the Closing occurs for purposes of applying deductibles, co-payments and out-of-pocket maximums as though such amounts had been paid in accordance with the terms and conditions of such Buyer Plan for the plan year in which the Closing occurs.

(d) Notwithstanding anything in this Agreement to the contrary, Seller will remain responsible for the administration of, and shall pay (and Seller hereby covenants and agrees that it shall ensure that neither Parent nor any other Buyer Indemnified Party shall have any Liability with respect to) all amounts and other Liabilities that become payable or owing to any Person pursuant to, the Thoratec Corporation Amended and Restated Nonqualified Deferred Compensation Plan, as amended, prior to, upon or following the Closing.

Nothing in this Section 6.4 shall constitute an amendment to any Benefit Plan, Buyer Plan or any other plan or arrangement covering Company employees and nothing in this Section 6.4 shall limit the ability of Buyer or its Affiliates from amending the terms of, or terminating, any Benefit Plan, Buyer Plan or any other plan or arrangement covering Company employees pursuant to the terms of such plan or arrangement. The Company and Buyer shall each cooperate with the other and shall provide to the other such documentation, information and assistance as is reasonably necessary to effect the provisions of this Section 6.4, including the transition from the Benefit Plans to Buyer Plans following the Transition Service Expiration Date.

6.5. Confidentiality.

(a) Each Party agrees that it shall not use any Confidential Information of any other Party or its Affiliates for any purpose other than in connection with the consummation of the transactions contemplated by this Agreement, whether or not consummated. The receiving Party will safeguard the Confidential Information against disclosure by employing the same means to protect the Confidential Information as it uses to protect its own non-public, confidential or proprietary information.

In the event that a Party becomes legally compelled (by deposition, interrogatory, request for documents, subpoena, civil investigative demand or similar process) to disclose any of the Confidential Information, such Party shall (to the extent permitted by applicable Law) give the other Party prompt prior written notice of such requirement so that they may seek a protective order or other appropriate remedy and/or waive compliance with the terms of this Section 6.5. In the event that such protective order or other remedy is not obtained, or that the Party waives compliance with the terms of this Section 6.5, the receiving Party agrees to provide only that limited portion of the Confidential Information that it is advised by counsel is legally required and to exercise reasonable best efforts to obtain assurance that confidential treatment will be accorded such Confidential Information. Each Party shall inform its employees, agents, lenders, financial and other advisors and Representatives of the confidential nature of such information and the obligation to keep such information confidential, and shall take such other action as shall be reasonably required to cause such information to be kept confidential. For purposes of this Agreement, “Confidential Information” shall mean any non-public, confidential or proprietary information, including any information relating to any Party or its Affiliates’ properties or operations; provided, however, that Confidential Information shall not include any information if:

(i) such information at the time of the disclosure or thereafter is generally available to the public (other than as a result of a disclosure by the receiving Party in violation of its confidentiality obligations set forth in this Section 6.5);

(ii) such information was available to the receiving Party on a non-confidential basis from a source other than the other Party; provided, however that such source was not known by the receiving Party to be bound by a confidentiality agreement or a duty of confidentiality that protected the Confidential Information; or

(iii) such information has been independently acquired or developed without use of Confidential Information by the receiving Party without violating any of its confidentiality obligations hereunder.

(b) Notwithstanding the foregoing, following Closing, (i) Buyer shall not be prohibited from disclosing to any Person any information relating to the Company, its business

or any Assets and (ii) with respect to Seller, the confidentiality obligations set forth in Section 6.5 shall apply to any Confidential Information that Seller has that relates to the Company, its business or any Assets.

6.6. Public Announcements. Except to the extent otherwise required by applicable Law or the rules and regulations of each stock exchange upon which the securities of a Party (or an Affiliate of such Party) are listed (and then only after consultation with Buyer or Seller, as applicable) or in connection with any litigation commenced by any Party hereto against any other Party hereto or any Affiliate thereof, none of the Parties will issue any press release or make any other public announcements concerning the transactions contemplated hereby or the contents of this Agreement without the prior written consent of the other Parties. If and to the extent that the terms set forth in this Section 6.6 conflict with the terms of Section 6.5, the terms set forth in this Section 6.6 shall control.

6.7. [Intentionally Omitted.]

6.8. Non-Competition; Non-Solicitation.

(a) Until the fifth anniversary of the Closing Date (the “Non-Competition Period”), Seller shall not, and shall cause each of its Subsidiaries and any other Person in which it holds, directly or indirectly, Controlling Equity Interests (such Persons, including their respective successors or assigns, are collectively referred to herein as the “Restricted Parties”), not to, directly or indirectly, form, own, manage, operate, join, control or participate (whether as a partner, agent, representative, or otherwise) in the ownership, management, operation or control of any Person in any territory in which the Company operates immediately prior to Closing or has taken reasonable measures as of the Closing Date to begin operating (the “Territory”), that, directly or indirectly competes with the business of the Company as it shall exist immediately prior to the Closing Date (including only changes or expansions in the business of the Company or the products sold or distributed by the Company that are expressly contemplated as of the Closing (including, for the avoidance of doubt, the Alternate Site Products)) (a “Competing Business”). In addition, during the Non-Competition Period, neither Seller nor any Restricted Party shall have, without Buyer’s prior written consent, any direct or indirect equity ownership in any such Person, other than as an owner of 2% or less of the outstanding stock of a publicly traded corporation. For the avoidance of doubt, Seller and the Restricted Parties shall not be restricted by the provisions of this Section 6.8 from acquiring (whether through a purchase of stock or assets, through a merger or consolidation, or otherwise) any Person that derives less than ten percent (10%) and less than $25,000,000 of its gross revenues (as measured from the conclusion of any of such Person’s last three completed fiscal years) from Competing Businesses in the aggregate; provided, however, that following an acquisition permitted by this sentence, if such acquired Person derives more than twelve percent (12%) or more than $30,000,000 of its gross revenues from Competing Businesses in the aggregate during any fiscal year that ends during the Non-Competition Period, Seller or such Restricted Party (as applicable) shall promptly provide written notice to Buyer of such fact and shall divest, as soon as reasonably practicable (but in any event within twelve months of providing such notice), a portion of the business of such Person that engages in Competing Businesses such that less than twelve percent (12%) and less than $30,000,000 of such Person’s gross revenues would be derived from

Competing Businesses during the remainder of the Non-Competition Period. Seller shall keep Buyer informed, on a reasonably current basis and in reasonable detail, of the status of Seller’s efforts to divest such business (or portion thereof) in accordance with the preceding proviso and Buyer shall have the right to participate as a potential purchaser in the sale process for such business (or portion thereof) on terms at least as favorable as those being offered to other participants in the sale process.

(b) Until the third anniversary of the Closing Date, Seller shall not, and shall cause each of the Restricted Parties not to, directly or indirectly, for itself or on behalf of any Person, (i) solicit for employment or hire any Company employee; provided, however that any such employee may seek employment with the applicable Person in response to a general advertisement not directed at such employee and the applicable Person may hire any employee who responds to such general advertisement; (ii) approach any supplier or licensee of the Company with respect to products or services it provided to the Company at any time during the twelve-month period prior to the Closing with the intention of harming the business or operations of the Company by causing such Person to decrease or cease doing business with the Company; or (iii) approach any Person who is a customer of the Company at any time during the twelvemonth period prior to the Closing with the intention of harming the business or operations of the Company by causing such Person to purchase the products of any business competitive with the Company.

(c) Seller acknowledges that the provisions set forth in this Section 6.8 are an integral part of the success of the Company throughout the Territory. If, on or after the Closing Date, Seller or any Restricted Party utilizes its reputation and goodwill in competition with Buyer, Buyer will be deprived of the benefits it has bargained for pursuant to this Agreement. In the event that the agreements in this Section 6.8 shall be determined by any court of competent jurisdiction to be unenforceable by reason of extending for too great a time or over too great a geographical area or by reason of it being too extensive in any other respect, it shall be interpreted to extend only over the maximum period of time for which it may be enforceable and/or over the maximum geographical area as to which it may be enforceable and/or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

(d) If Seller or any Restricted Party breaches or threatens to commit a breach of any of the restrictive covenants set forth in this Section 6.8, then the Company and Buyer shall each have the following rights and remedies against Seller or such Restricted Party, each of which shall be independent of the others and severally enforceable, and each of the following rights and remedies is in addition to, and not in lieu of, any other rights and remedies otherwise available to any of them at Law or in equity: the right and remedy to have the restrictive covenants in this Section 6.8 specifically enforced against the Seller or such Restricted Party, including temporary restraining orders and injunctions by any court of competent jurisdiction, it being agreed by Seller that any breach or threatened breach by Seller or any Restricted Party of this Section 6.8 would cause irreparable injury to the Company and Buyer and that money damages would not provide an adequate remedy to the Company or Buyer.

(e) Each of Seller and Buyer intends that the covenants set forth in Sections 6.8(a) and 6.8(b) shall be deemed to be a series of separate covenants, one for each county or province of each and every state, territory or jurisdiction within the Territory, and one for each month of the time periods covered by such covenants.

(f) Seller hereby agrees that in the event a court of competent jurisdiction declares there has been a breach by Seller or any Restricted Party of Section 6.8(a) or Section 6.8(b), the term of any such covenant so breached shall be automatically extended beyond its intended expiration for a period of time equal to the duration of such breach.

(g) Seller shall be responsible for any breach of this Section 6.8 by any of its Subsidiaries or any other Person in which Seller holds, directly or indirectly, Controlling Equity Interests.

6.9. [Intentionally Omitted].

6.10. Insurance. Buyer shall be solely responsible for providing insurance to the Company for any event or occurrence after the Closing. Without limiting the rights of Buyer set forth elsewhere in this Agreement, if any Claims may reasonably be made, or if Losses have occurred prior to the Closing Date that relate to the Company, and such Claims may be made against insurance policies retained by Seller or its Affiliates, then Seller (on behalf of itself and its Affiliates) shall, at Buyer’s request and at Buyer’s sole cost and expense, use its reasonable best efforts in an effort to permit Buyer (after the Closing Date and in cooperation with Seller) to file, notice and otherwise continue to pursue such Claims and recover proceeds under the terms of such policies, and, subject to all of the foregoing, Seller (on behalf of itself and its Affiliates) agrees (at Buyer’s sole cost and expense) to otherwise reasonably cooperate with Buyer or its Affiliates to make the benefits of any such insurance policies available to Buyer or its Affiliates.

6.11. Checks Payable; Payroll; Cash.

(a) From and after the Closing, Seller shall remain liable for and shall honor and pay (and Seller hereby covenants and agrees that it shall ensure that neither Parent nor any other Buyer Indemnified Party shall have any Liability with respect to) any and all checks or other instruments of payment written or issued on or prior to the Closing Date by Seller or ITC, in each case that have not been settled or otherwise satisfied on or prior to the Closing Date and that relate to the business or operations of ITC.

(b) On or as soon as practicable following the Closing Date, Seller shall pay (and Seller hereby covenants and agrees that it shall ensure that neither Parent nor any other Buyer Indemnified Party shall have any Liability with respect to) the payroll of ITC otherwise due and payable November 5, 2010.

(c) Any Cash or checks received by the Company on November 3, 2010 in the total amount of less than or equal to two hundred and twenty-five thousand dollars ($225,000) shall be maintained by the Company for the benefit of the Buyer following the Closing and shall not be distributed by the Company to Seller, provided, that in the event that the Company receives Cash

or checks in excess of two hundred and twenty-five thousand dollars ($225,000) on such date, Seller may cause the Company to distribute such excess amount to Seller.

6.12. Cooperation; Financial Reporting. Buyer agrees to furnish or cause to be furnished, upon written request, information and assistance of employees of the Company relating to the pre-Closing operation of the business of the Company as is necessary in the reasonable judgment of Seller in order for Seller (i) to satisfy on a timely basis its financial reporting obligations related to the Company pursuant to the Exchange Act until the date of filing of Seller’s 10-K for the 2010 fiscal year of Seller and (ii) from the date of filing of Seller’s 10-K for the 2010 fiscal year of Seller until two (2) years from such date, to satisfy any other legitimate legal obligation (as determined by Seller in good faith) or financial reporting obligation of Seller relating to the pre-Closing operation of the business of the Company and identified to Buyer in writing. The obligations of Buyer pursuant to clause (i) above shall include access at reasonable times within normal business hours to all books and records of the Company relating to the pre-Closing operation of the business of the Company as may be reasonably requested by Seller and the assistance of all personnel of the Company, who, in the Ordinary Course of Business of the Company as of the date hereof, perform services or otherwise aid Seller with respect to such reporting obligations; provided, that in no event shall such access or assistance unreasonably interfere with the operation of the Company’s business or the duties of such personnel to the Company. The obligations of Buyer pursuant to clause (ii) above shall include access at reasonable times within normal business hours to the specific books and records of the Company required for the purpose specified by Seller in its request for such services and the assistance of certain personnel of the Company to be mutually agreed between Buyer and Seller; provided, that in no event shall such access or assistance unreasonably interfere with the operation of the Company’s business or the duties of such personnel to the Company. Buyer shall be obligated to provide the services set forth in clauses (i) and (ii) at a cost to Seller consistent with the hourly rates of the employees performing such services (or, if such employees are salaried employees, at a reasonable approximation of such employee’s per hour salary) and Seller shall reimburse Buyer for all out-of-pocket expenses incurred by Buyer or the Company in providing such services. For the avoidance of doubt, cooperation obligations related to Taxes are addressed solely in Section 10.4. In no event shall Buyer or the Company or any of their respective Affiliates have any Liability in respect of any reasonable act or omission of any employee of the Company with respect to the performance of the services contemplated by this Section 6.12 or otherwise in connection with any information provided to Seller by Buyer, the Company or any Affiliate thereof pursuant to the terms set forth in this Section 6.12. All Confidential Information of either Party of which the other Party becomes aware during the provision of the services contemplated by this Section 6.12 shall be treated in accordance with Section 6.5. Notwithstanding anything to the contrary in this Agreement, (A) Buyer shall not be required to take any action pursuant to this Section 6.12 if there is a legitimate business reason for not taking such action, as determined in good faith by Buyer, and (B) Buyer need not supply Seller with any access or information which Buyer or any of its Affiliates is under a legal or contractual obligation not to supply.

6.13. Title Insurance and Surveys. With respect to the Owned Real Property, Seller shall use commercially reasonable efforts to assist Buyer (at Buyer’s sole cost and expense) in obtaining title insurance policies and surveys in form and substance satisfactory to Buyer,

including removing from title any Encumbrances (other than Permitted Encumbrances). Seller shall provide Buyer’s title company with any affidavit, indemnity or other assurances reasonably requested by such title company in order to issue such title insurance policies.

SURVIVAL AND INDEMNIFICATION

9.1. Survival.

(a) Each and every representation and warranty contained in this Agreement (other than the Surviving Representations and Warranties) shall expire as of the Closing. Each Specified Representation and Warranty shall survive the Closing Date until the date that is twelve (12) months from the Closing Date and then expire. Each Fundamental Representation and Warranty shall survive the Closing Date until sixty (60) days following the expiration of the longest applicable statute of limitation applicable to such Fundamental Representation and Warranty, or underlying Claims that may constitute a breach thereof.

Each Surviving Covenant shall survive the Closing Date until, and will expire sixty (60) days following the expiration of the statute of limitation applicable to such covenant. The indemnification obligations of Seller set forth in Section 9.2(a)(iii) shall survive the Closing Date until sixty (60) days following the expiration of the statute of limitations that is applicable to the applicable Pre-Closing Tax which may be subject to indemnification pursuant to Section 9.2(a)(iii). The indemnification obligations of Seller set forth in Section 9.2(a)(iv) shall survive the Closing until the date that is five (5) years from the Closing Date and then expire. The indemnification obligations of Seller set forth in Section 9.2(a)(v) shall expire on the twelve (12) month anniversary of the Closing Date.

(c) Any representation, warranty or covenant in respect of which indemnity may be sought under this Article IX (including, without limitation, covenants to provide indemnification pursuant to Sections 9.2(a)(iii), 9.2(a)(iv) and 9.2(a)(v)), and the indemnity obligations of the applicable Party with respect thereto, shall survive the time at which it would otherwise terminate pursuant to this Section 9.1 if written notice of the Claim giving rise to such right or

potential right of indemnity shall have been given to the Party against whom such indemnity may be sought prior to such time and, in any such case, such representation, warranty or covenant and the indemnification obligations with respect thereto shall survive until any Claim (and any Claim arising out of similar facts and circumstances) for indemnity related thereto is settled or fully resolved.

9.2. Indemnification.

(a) From and after the Closing, Seller shall indemnify, defend (subject to Section 9.2(c)) and hold harmless the Buyer Indemnified Parties from and against any and all Losses incurred, suffered or sustained by any Buyer Indemnified Party in connection with, arising out of or resulting from (directly or indirectly): (i) any breach of any Surviving Representation and Warranty and any Third Party Claim alleging facts that, if true, would constitute such a breach of any Surviving Representation and Warranty; (ii) any breach of any Surviving Covenant by Seller; (iii) any Pre-Closing Taxes; (iv) any Claim by any Person who was an officer, director or stockholder of the Company, or the holder of a stock option, restricted stock, restricted stock unit, or other equity award relating to Seller’s common stock, at any time prior to the Closing, which Claim is made in such capacity, to the extent such Claim does not arise from any action of Buyer Indemnified Parties after the Closing; and (v) the occurrence of any FDA Event.

(b) From and after the Closing, Buyer shall indemnify, defend (subject to Section 9.2(c)) and hold harmless the Seller Indemnified Parties from and against any and all Losses incurred, suffered or sustained by any Seller Indemnified Party in connection with, arising out of or resulting from (directly or indirectly): (i) any breach of any representation or warranty made by Buyer in Article V and any Third Party Claim alleging facts that, if true, would constitute such a breach of any representation or warranty; and (ii) any breach of any Surviving Covenant by Buyer.

(c) If a Claim for Losses is to be made by a Party entitled to indemnification hereunder with respect to any Claim or other assertion of Liability by a third party (a “Third Party Claim”), the Party claiming such indemnification shall give written notice (a “Claim Notice”) to the indemnifying Party as soon as reasonably practicable after the Party entitled to indemnification becomes aware of any fact, condition or event which may give rise to Losses for which indemnification may be sought under this Section 9.2 with respect to any Third Party Claim; provided, however, if any Action is filed against any Party entitled to the benefit of and seeking indemnity hereunder for a Third Party Claim, the applicable Claim Notice shall be given to the indemnifying Party within twenty (20) Business Days after the service of the citation or summons (the “Notice Period”). Notwithstanding the foregoing, the failure of any indemnified Party to give timely notice hereunder shall not affect rights to indemnification hereunder, except and only to the extent that the indemnifying Party is actually and materially prejudiced by such failure. The Parties understand and agree that the failure of the indemnified Party to so notify the indemnifying Party prior to settling any such Third Party Claim (whether by paying the Third Party Claim or executing a binding settlement agreement with respect thereto) shall constitute actual and material prejudice to the indemnifying Party’s ability to defend against such Third Party Claim; provided, that the indemnified Party is hereby authorized (but not obligated) prior to and during the Notice Period to file any motion, answer or other pleading and to take any

other action which the indemnified Party shall deem necessary or appropriate to protect the indemnified Party’s interests. After receiving a Claim Notice, the indemnifying Party shall be entitled, upon written notice to the indemnified Party, at its own cost, risk and expense, (i) to take control of the defense and investigation of such Action, (ii) to employ and engage attorneys of its own choice (reasonably acceptable to the indemnified Party) to handle and defend the same (unless the named parties to such Action include both the indemnifying Party and the indemnified Party, and the indemnified Party has been advised by counsel that (A) there may be one or more legal defenses available to such indemnified Party that are different from or additional to those available to the indemnifying Party or (B) there are issues that raise actual or likely conflicts of interest between the indemnifying Party and the indemnified Party, in which event the indemnified Party shall be entitled, at the indemnifying Party’s cost, risk and expense, to separate counsel of its own choosing) and (iii) to compromise or settle such Third Party Claim, which compromise or settlement shall be made only with the prior written consent of the indemnified Party, such consent not to be unreasonably withheld or delayed; provided, however, that the indemnifying Party shall not be entitled to assume control of such defense and shall pay the fees and expenses of counsel retained by the indemnified Party, if (1) the indemnifying Party does not agree in writing to be fully responsible for all Losses relating to such Third Party Claim; (2) the Third Party Claim involves a Governmental Authority; (3) the Third Party Claim relates to or arises in connection with any criminal Action; or (4) the Third Party Claim seeks equitable relief or any other non-monetary remedy against the indemnified Party. In the event the indemnifying Party takes control of the defense and investigation of such a Claim, the indemnified Party may, at its own cost and expense, participate in the investigation, trial and defense of such Action and any appeal arising therefrom (it being understood that the indemnifying Party shall control such defense). If the indemnifying Party fails to assume the defense of such Third Party Claim within fifteen (15) Business Days after receipt of the Claim Notice, the indemnified Party against which such Third Party Claim has been asserted will (upon delivering notice to such effect to the indemnifying Party) have the right to undertake, at the indemnifying Party’s cost and expense, the defense, compromise or settlement of such Third Party Claim on behalf of and for the account and risk of the indemnifying Party. Any Third Party Claim the defense of which is assumed by an indemnified Party shall not be compromised or settled without the prior written consent of the indemnifying Party, which consent shall not be unreasonably withheld or delayed. In the event the indemnified Party assumes the defense of a Third Party Claim, the indemnified Party will keep the indemnifying Party reasonably informed of the progress of any such defense, compromise or settlement. The Parties shall cooperate in all reasonable respects with each other in the investigation, trial and defense of any Third Party Claim for Losses or Action and any appeal arising therefrom.

(d) If an indemnified Party asserts a Claim which does not involve a Third Party Claim, the indemnified Party shall provide a Claim Notice to the indemnifying Party prior to the expiration of the relevant survival period specified in Section 9.1. If the indemnifying party does not notify the indemnified Party within twenty (20) Business Days of its receipt of the Claim Notice that the indemnifying Party disputes such Claim, the amount of such Claim shall be conclusively deemed a liability of the indemnifying Party hereunder. If the indemnifying Party makes an objection in writing (which such writing must include a reasonable description of the indemnifying Party’s basis for such objection(s)), the indemnified Party shall have fifteen (15) Business Days to respond in a written statement to the objection(s). If after such fifteen (15)

Business Day period there remains a dispute as to any such Claim, the Parties shall attempt in good faith for twenty (20) Business Days to agree upon the rights of the respective Parties with respect to such Claim. If the Parties should so agree, a memorandum setting forth such agreement shall be prepared and signed by both Parties. If such Parties shall not agree, an indemnified Party shall be entitled to initiate an Action and seek remedies as may be permitted under the terms of this Agreement.

(e) In the event of payment in full by the indemnifying Party to the indemnified Party in connection with any Claim (an “Indemnified Claim”), the indemnifying Party shall be subrogated to and shall stand in the place of the indemnified Party as to any events or circumstances in respect of which the indemnified Party may have any right or Claim relating to such Indemnified Claim against any claimant or plaintiff asserting such Indemnified Claim or against any other Person. The indemnified Party shall cooperate with the indemnifying Party in a reasonable manner, and at the cost and expense of the indemnifying Party, in prosecuting any subrogated right or Claim.

(f) The Parties shall reasonably cooperate with each other with respect to resolving any Claim or Liability with respect to which one Party is obligated to indemnify another Party hereunder, including, at the written request of, and at the sole cost and expense of, the indemnifying Party, using commercially reasonable efforts to mitigate any such Claim or Liability.

(g) For purposes of determining whether there has been a breach of any representation or warranty contained in this Agreement, or the amount of any Loss related to a breach of any representation or warranty contained in this Agreement, the representations and warranties contained in this Agreement shall be considered without regard to any “material,” “Material Adverse Effect” or similar qualifications contained therein. The representations, warranties and covenants contained in this Agreement shall not be affected by any investigation, inquiry or examination made for or on behalf of any Party, or the knowledge of any Party of a breach of any representation, warranty or covenant by the other Party.

9.3. Limitations on Indemnification.

(a) Except as provided in the penultimate sentence of this Section 9.3(a), notwithstanding anything to the contrary contained in this Agreement, (i) no indemnification under Section 9.2(a)(i) or Section 9.2(a)(v) hereof shall be made by Seller and no indemnification under Section 9.2(b)(i) hereof shall be made by Buyer, and neither Seller nor Buyer shall have any Liability, respectively, to the other therefor, unless and until the aggregate amount of Losses subject to indemnification pursuant thereto and due the Party being indemnified shall exceed $1,000,000 (the “Threshold Amount”), and once the Threshold Amount is exceeded the indemnifying Party shall indemnify the indemnified Party, and shall be liable, only for the amount of any such Losses in excess of the Threshold Amount; (ii) the aggregate amount required to be paid by Seller pursuant to its indemnification obligations under Section 9.2(a)(i) hereof or by Buyer pursuant to its indemnification obligations under Section 9.2(b)(i) hereof shall not exceed an amount equal to $5,500,000 (which, for purposes of calculating this amount, (x) excludes the Threshold Amount and (y) includes all amounts paid by Seller pursuant

to its indemnification obligations under Section 9.2(a)(v)), and neither Party shall have any Liability to any indemnified Party for, and such indemnified Parties shall have no right to recover from Seller or Buyer, as the case may be, any amount of Losses pursuant to such indemnification obligations which exceeds (and from and after the time such Losses exceed) such amount; (iii) no indemnification under Section 9.2(a)(i) hereof shall be made by Seller and no indemnification under Section 9.2(b)(i) hereof shall be made by Buyer, and neither Seller nor Buyer shall have any Liability, respectively, to the other for any individual Claim or any Liability arising out of or resulting from a single action, event, occurrence or a set of circumstances, unless such individual Claim or such Liability arising out of or resulting from a single action, event, occurrence or a set of circumstances is greater than $37,500; provided, that in the case of clause (iii) above, any Claims or Liabilities resulting from similar facts or circumstances shall be aggregated for the purposes of determining whether such Claims or Liabilities are indemnifiable pursuant to such clause; and (iv) Seller’s indemnification obligations pursuant to Section 9.2(a)(v) shall not exceed an amount equal to $7,000,000 (which, for purposes of calculating this amount, shall be deemed to include all amounts paid by Seller pursuant to its indemnification obligations under Section 9.2(a)(i), whether or not related to an FDA Event). Notwithstanding anything set forth herein to the contrary, the applicable indemnified Party shall be entitled to indemnification without regard to any of the provisions of this Section 9.3(a) with respect to (1) indemnification obligations for Losses relating to any breach (and any Third Party Claim alleging facts that, if true, would constitute such a breach) of (x) the Fundamental Representations and Warranties, or (y) any of the Specified Representations and Warranties set forth in the last sentence of Section 4.9(a), or in Section 4.21(l), or in Section 4.21(m), (2) Claims of fraud, intentional misrepresentation or willful breach of this Agreement, or (3) Claims pursuant to Section 9.2(a)(ii), 9.2(a)(iii), 9.2(a)(iv) or Section 9.2(b)(ii); provided, however, that the aggregate Liability (other than with respect to Claims for fraud, intentional misrepresentation or willful breach of this Agreement) of Seller or Buyer under Section 9.2(a) (other than under Section 9.2(a)(iii) or under Section 9.2(a)(ii) in respect of the Surviving Covenants set forth in Sections 6.4, 6.5 or 6.8) and Section 9.2(b), respectively, shall in no event exceed the Purchase Price.

(b) To the extent that any Losses or Claim therefor which is subject to indemnification hereunder are covered by insurance held by any indemnified Party (an “Insured Loss”), such indemnified Party shall only be entitled to indemnification pursuant to Section 9.2 hereof with respect to the amount of Losses in excess of the net cash proceeds actually received by such indemnified Party pursuant to such insurance (after deducting the out-of-pocket costs and expenses incurred in connection with obtaining such proceeds, excluding incremental insurance premium costs). With respect to any Insured Loss, the applicable indemnified Party shall first use all commercially reasonable efforts to obtain the maximum recovery from the provider of such insurance and then, to the extent that the net cash proceeds received by such indemnified Party (after deducting the out-of-pocket costs and expenses incurred in connection with obtaining such proceeds, excluding incremental insurance premium costs) are less than the amount of the Losses indemnified hereunder, or if the indemnified Party is unable to promptly obtain full recovery from such provider, the indemnified Party shall be entitled to seek indemnification pursuant to Section 9.2 hereof with respect to the amount of the Losses that exceed such recovery, if any; provided, however, that if, following the receipt of any indemnity payments pursuant to Section 9.2 hereof, the indemnified Party obtains any insurance recovery

from a third party insurance provider, with respect to such Losses, then such indemnified Party shall promptly pay over to the indemnifying Party (in proportion to their relative payments in respect of the underlying Loss) the amount of the net cash proceeds received by such indemnified Party pursuant to such insurance (after deducting the out-of-pocket costs and expenses incurred in connection with obtaining such proceeds, excluding incremental insurance premium costs) up to, but not in excess of, the amount of the indemnity payments made by the indemnifying Party pursuant to such Losses. The Parties agree that (i) no insurance company shall have any right of subrogation under this Section 9.3(b), (ii) this Section 9.3(b) is not for the benefit of any third party insurance provider and (iii) this Section 9.3(b) shall not require any indemnified Party to initiate, engage in or threaten litigation with any of its insurance carriers.

(c) Except for (i) equitable relief, including, without limitation, injunctive relief or specific performance, to which either Party hereto may be entitled pursuant to other Sections of this Agreement, and (ii) Claims of fraud, intentional misrepresentation or willful breach of this Agreement, the indemnification provided in this Article IX and Section 10.3 shall be the sole and exclusive remedy of the Parties for monetary damages for any breach of any representation, warranty or covenant contained in this Agreement.

(d) Notwithstanding anything to the contrary in this Agreement, Losses indemnifiable under this Article IX hereof shall expressly exclude punitive damages, except for any such Losses arising out of Third Party Claims (which shall be indemnifiable by the indemnifying Party for all such damages).

(e) Notwithstanding anything to the contrary herein, Seller shall not be obligated to indemnify, defend and hold harmless the Buyer Indemnified Parties from and against any Losses incurred, suffered or sustained by any Buyer Indemnified Party in connection with, arising out of or resulting from any breach of the representations or warranties made by Seller in Section 4.15 where the matter giving rise to such Losses is discovered as a result of any Buyer Indemnified Parties conducting sampling and analysis of soil or groundwater at any Company Real Property after the Closing Date, except to the extent such sampling is: (i) required by Environmental Laws, including a permit issued pursuant to Environmental Laws; (ii) required by a Governmental Order; (iii) reasonably necessary to investigate identified conditions that indicate an imminent or substantial endangerment to health or the environment; (iv) reasonable to defend against or otherwise respond to a Third Party Claim; (v) with respect to Leased Real Property, necessary to comply with the requirements of the lease agreement pertaining to such Leased Real Property; (vi) requested in writing by a lender or prospective purchaser in connection with a sale, lease, financing or mortgage involving any Company Real Property; or (vii) conducted in connection with proposed construction or expansion at any the Company Real Property, to the extent such sampling is consistent with industry practice, provided, that for the avoidance of doubt, the indemnification of any Buyer Indemnified Parties shall not be limited by any Buyer Indemnified Party conducting sampling or analysis of any drinking water or production water ▇▇▇▇▇ that may exist on the Closing Date at any Company Real Property, or of any wastewater discharges at any Company Real Property, or of any indoor or outdoor air at any Company Real Property.

ARTICLE X.

TAX MATTERS

10.1. Preparation of Tax Returns.

(a) Seller shall, at its own expense, prepare and timely file all Tax Returns of or including the Company for any Pre-Closing Taxable Period or Straddle Period required to be filed after the Closing Date which Tax Returns also include Seller or any other Subsidiary thereof (such Tax Returns, “Seller Group Returns”) and shall timely pay any Taxes due in respect of such Seller Group Returns. Such Seller Group Returns shall be prepared consistent with past practice, except as otherwise required by Law. Solely as relates to the Company, a copy of each such Seller Group Return shall be delivered to Buyer at least 5 Business Days prior to the filing of such Seller Group Return for Buyer’s review and reasonable comment.

A copy of each such Separate Company Return shall be delivered to Seller at least 15 days prior to the due date of such Separate Company Return for Seller’s review and approval (which approval shall not be unreasonably withheld, conditioned or delayed), and all reasonable comments of Seller shall be reflected on such Separate Company Returns prior to filing.

(c) Neither Buyer nor any of its Affiliates shall (or shall cause or permit the Company or any of its Subsidiaries to) file, amend, refile or otherwise modify any Tax Return relating in whole or in part to the Company with respect to any Pre-Closing Taxable Period (or with respect to any Straddle Period) without the prior written consent of Seller, which consent shall not be unreasonably withheld, conditioned or delayed.

(d) Seller shall be entitled to the amount of any refund or credit of Pre-Closing Taxes, which refund or credit is actually realized by Buyer or its Subsidiaries (including the Company) after the Closing, net of any Tax cost to Buyer and its Subsidiaries as a result of the receipt of such refund or credit. Buyer shall pay, or cause to be paid, to Seller any amount to which Seller is entitled pursuant to the prior sentence within two Business Days of the receipt or recognition of the applicable refund or credit by Buyer or its Subsidiaries. To the extent requested by Seller, Buyer will reasonably cooperate with Seller in obtaining such refund or credit, including through the filing of amended Tax Returns for periods ending before or on the Closing Date or refund claims. To the extent such refund or credit is subsequently disallowed or required to be returned to the applicable Governmental Authority, Seller agrees to repay the amount of such refund or credit, together with any interest, penalties or other additional amounts imposed by the applicable Governmental Authority, to Buyer.

(e) Notwithstanding anything in this Agreement to the contrary, Buyer and Seller agree that, for income tax reporting purposes, (i) the vesting in connection with the Closing of

restricted stock units of Seller held by employees or former employees of the Company, and any payments made to such employees or former employees in respect of such vesting, shall be deemed to occur immediately prior to the Closing and shall be allocable to the Pre-Closing Tax Period for all tax reporting purposes, and any payroll Taxes associated with such vesting shall be treated as a Pre-Closing Tax notwithstanding the last sentence of the definition of “Pre-Closing Taxes”; (ii) deductions arising from the vesting in connection with the Closing of restricted stock of Seller held by employees or former employees of the Company shall be allocable to the Tax period of the Company beginning after the Closing Date, and any payroll Taxes associated with such vesting shall not be treated as a Pre-Closing Tax; and (iii) deductions arising from the exercise after the Closing Date by employees or former employees of the Company of options to purchase Seller stock shall be allocable to the Tax period of the Company beginning after the Closing Date, and any payroll Taxes associated with such vesting shall not be treated as a Pre-Closing Tax.

10.2. Transfer Taxes. All sales, use, transfer, stamp, registration, documentary, excise, real property transfer, or similar Taxes incurred as a result of the transactions contemplated by this Agreement shall be borne 50% by Buyer and 50% by Seller.

10.3. Cooperation; Taxes. Buyer and Seller agree to furnish or cause to be furnished to the other, upon request, as promptly as practicable, such information and assistance relating to Taxes, including, without limitation, access to books and records, as is reasonably necessary for the filing of all Tax Returns, the making of any election relating to Taxes, the preparation for any audit by any taxing authority and the prosecution or defense of any Claim, suit or proceeding relating to any Tax. Each of Buyer and Seller shall retain all books and records with respect to Taxes for a period of at least seven (7) years following the Closing Date.

10.4. Tax Treatment of Indemnification Payments. Any indemnification payments made pursuant to Article 9 shall be treated as adjustments to the Purchase Price for Tax purposes.

10.5. Tax Claims. Notwithstanding anything in this Agreement to the contrary, Seller shall have sole control of the conduct and defense of any audits, disputes, proceedings and Claims involving a Governmental Authority with respect to Pre-Closing Taxes (a “Tax Claim”); provided, however, that Seller shall (i) keep Buyer reasonably informed of material developments of the progress of such Tax Claim and (ii) shall not settle or compromise such Tax Claim without the prior written consent of Buyer, not to be unreasonably withheld, conditioned or delayed, in each of (i) and (ii) to the extent such Tax Claim relates to a Straddle Period or the resolution of such Tax Claim could reasonably be expected to materially and adversely affect the liability of Buyer or its Affiliates for Taxes (taking into account Seller’s indemnification obligations hereunder). In the event of any conflict between this Article X and the provisions of Article IX, the provisions of this Article X shall control.

matter is correct or is not breached will not affect the incorrectness of or a breach of a representation and warranty hereunder.

TRANSITION SERVICES AGREEMENT

THIS TRANSITION SERVICES AGREEMENT, dated as of November 4, 2010 (together with all Schedules hereto, as the same may from time to time be amended, modified, supplemented or restated in accordance with the terms hereof, this “Agreement”), is by and between International Technidyne Corporation, a Delaware corporation (the “Company”), and Thoratec Corporation, a California corporation (“Seller” or “Thoratec”). All capitalized terms used herein but not otherwise defined shall have the meanings given to them in the Purchase Agreement (as defined below).

W I T N E S S E T H :

WHEREAS, Seller and ITC Nexus Holding Company, Inc., a Delaware corporation (“Buyer”), are parties to that certain Stock Purchase Agreement, dated as of even date herewith (as the same may be amended, modified or supplemented from time to time in accordance with its terms, the “Purchase Agreement”); and

WHEREAS, in connection with the transactions contemplated by the Purchase Agreement and pursuant to Section 3.3(a) thereof, Seller and Buyer agreed to enter into this Agreement on the terms and subject to the conditions set forth herein.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

1. Provision of Services. Subject to the terms and conditions of this Agreement, during the Term (as defined in Section 5), Seller agrees to provide to the Company all of the services set forth on Schedule I attached hereto (collectively all of the services provided by Seller hereunder, the “Services”). Seller shall not be required to perform a Service if the provision of such Service by Seller conflicts with or violates applicable law; provided that Seller uses commercially reasonable efforts to promptly resolve the conflict or violation, and provide such Services to the Company promptly thereafter. Any costs incurred in connection with any such resolution will be paid in accordance with Section 3.

2. Standard of Performance. Seller shall provide to the Company the Services substantially to the same extent, substantially for the same purposes, in substantially the same manner, with substantially the same degree of care (which in no event may be less than reasonable care) as Seller has provided such Services to the Company during the twelve-month period prior to the date hereof; provided, that at all times the Services shall be performed in a timely, efficient, and workmanlike manner; provided, further, that in no event shall Seller have any Liability to the Company in respect of any reasonable act or omission of any employee of Seller with respect to the performance of the Services. The Company shall use the Services substantially to the same extent, substantially for the same purposes and in substantially the same manner as the Company used the Services during the twelve-month period prior to the date hereof. During the Term of this Agreement with respect to Health and Welfare Benefits Services as set forth in Section 5(a)(i), the Company will not terminate in excess of twenty employees of the Company covered by such Health and Welfare Benefits Services provided by Seller.

3. Fees; Payment Terms.

(a) Except as set forth in Section 5, the cost to the Company for each Service shall be the cost to Seller of providing such Service (which includes any out-of-pocket expenses incurred by Seller relating thereto as set forth on Schedule I, provided, for the avoidance of doubt, except with respect to the Audit Services set forth on Schedule I, such cost shall not include any salary, benefits or other compensation paid to employees of Seller providing such Services). The Company shall also pay all applicable federal, state, local and foreign stamp, sales, use, privilege, service, value-added, excise or other Taxes paid or payable by Seller in connection with providing the Services (excluding U.S. federal, state, local or foreign income or franchise Taxes imposed on the net income of Seller) (“Covered Taxes”). In addition, all fees for Services shall be paid without any deduction or withholding for Covered Taxes unless such deduction or withholding is required by law. If such deduction or withholding is required by law, the amounts payable by the Company hereunder will be increased so that after giving effect to all such deductions or withholdings (including upon such increased amounts) Seller receives the same net amount Seller would have received had no such deduction or withholding been required.

	(v)		with respect to Services set forth on Schedule I under the heading “Treasury Services” (the “Treasury Services”), the amount set forth on the statement of account that Seller submits to the Company within thirty (30) days after the end of the Term for each such Service (the “Treasury Services Invoiced Amount” and together with the Benefits Invoiced Amount, the Audit Services Invoiced Amount, the International Payroll Services Invoiced Amount and the IT Services Invoiced Amount, the “Invoiced Amounts”), such undisputed Treasury Services Invoiced Amounts shall be paid by the Company within thirty (30) days after receipt of such statements.

Seller agrees to afford the Company, upon reasonable notice, access to such information, records and documentation of Seller as the Company may reasonably request in order to verify the Invoiced Amount.

4. Tax Withholding on Option Exercises. In the event that an employee or former employee of the Company exercises an option to purchase Seller common stock for which tax withholding obligations will be incurred by the Company during the Term, then as soon as administratively practicable following such exercise Seller shall remit an amount to the Company equal to such tax withholding obligations. The Company will bear the amount of the employer portion of any employment tax obligations incurred as a result of such exercise.

Each party hereto further irrevocably submits to the jurisdiction of any such court in any such claim.

CONTRACT, TORT, EQUITY, OR OTHERWISE. EACH PARTY TO THIS AGREEMENT HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAM, DEMAND, ACTION, OR CAUSE OF ACTION WILL BE DECIDED BY TRIAL WITHOUT A JURY AND THAT THE PARTIES TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.
