NOW, THEREFORE, in consideration of the mutual covenants and agreements set forth herein and other good and valid consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereby agree as follows:

ARTICLE I

SERVICES

1.1 Services.

(a) As partial consideration for Buyer’s payment of the Cash Portion of the Purchase Price and subject to the terms and conditions of this Agreement, Seller shall provide, and, as applicable, shall cause its Affiliates, Representatives and Authorized Third Parties to provide, to Company and the Subsidiaries the services described on Exhibit A attached hereto (the “Services”) for the period from the Closing Date until the termination or expiration of this Agreement pursuant to Article III below (the “Transition Period”) solely to the extent that (1) such Services are provided by Seller or its Affiliates to Company or any of the Subsidiaries as of the Closing Date, and (2) such Services are reasonably necessary to support during the Transition Period the operation of Company and the Subsidiaries in all material respects as they were operated as of the Closing Date. Seller shall provide the Services to Company and the Subsidiaries in substantially the same manner as Seller provided such services to Company and the Subsidiaries as of the Closing Date. For purposes of this Agreement, “Representatives” means, with respect to Seller, its directors, officers, employees, financial advisors, attorneys, accountants, consultants, agents and other authorized representatives, acting in such capacity.

(b) Seller shall, and as applicable, shall cause its Affiliates, Representatives and Authorized Third Parties to, (i) materially comply with all applicable Laws relating to the performance of the Services; and (ii) materially comply with any reasonable confidentiality, security, privacy or other policies of Company and the Subsidiaries relating to the performance of the Services which have been provided to Seller reasonably in advance.

(c) To the extent permitted by applicable Law, Seller agrees to pass through to Company and the Subsidiaries any rights Seller may have with respect to Authorized Third Parties in connection with any failure by such Authorized Third Parties to materially comply with all applicable Laws relating to the performance of the Services or to materially comply with any reasonable confidentiality, security, privacy or other policies of Seller or Company or the Subsidiaries relating to the performance of the Services.

(d) Company shall use, and shall cause the Subsidiaries to use, the Services only for substantially the same purpose and in substantially the same manner and amount as the Services were used by Company and the Subsidiaries as of the Closing Date; provided, however, that the scope and amount of the Services may be reduced by Company as specified herein.

(e) Notwithstanding anything herein to the contrary, the Services shall not include (i) the provision of any funding or financial accommodation and (ii) any service that is directly provided by any third party to Company or any of the Subsidiaries under an agreement between such third party and Company or any such Subsidiary.

1.2 Additional Services. Company may request that Seller and/or its Affiliates and Authorized Third Parties provide additional transition services required by Company or the Subsidiaries which have not been addressed herein and which are reasonably necessary to support the operation of Company or any Subsidiary during the Transition Period as Company or such Subsidiary was operated in all material respects as of the Closing Date. Company shall request such additional services from Seller in writing within thirty (30) calendar days of the Closing Date. Within five (5) Business Days of Seller’s receipt of Company’s written request for such additional services, the Service Coordinators (as defined below) shall commence negotiations, in good faith, with respect to the scope, duration and price (which may be a market price) of such additional services to be provided during the Transition Period. Within five (5) Business Days of agreement on such items, the parties shall work in good faith to set forth the additional agreed-upon services in a new services description, in a format similar to that set forth in Exhibit A. Upon the mutual written agreement to such new services description, the additional agreed-upon services shall be deemed “Services” under this Agreement, and such new schedule shall be deemed incorporated into Exhibit A and shall in all other respects be subject to the terms and conditions of this Agreement. Notwithstanding the foregoing, Seller has no obligation to agree to provide any service pursuant to this Section 1.2 to the extent such service (a) (i) had not been provided by Seller, its Affiliates or any Authorized Third Party to Company or any of the Subsidiaries as of the Closing Date (“Existing Services”) and (ii) is not related to the transition from the Existing Services; or (b) does not require any historical or institutional knowledge or unique capabilities on the part of Seller or its Affiliates.

1.3 Service Schedules. The parties acknowledge and agree that the descriptions of Services in Exhibit A are general only and do not purport to contain an exhaustive description of the Services to be provided. The parties further acknowledge and agree that it may not be practicable to describe each and every aspect of a particular Service in detail; therefore, each Service that is generally agreed upon by the parties and included in Exhibit A will be provided in accordance with the applicable terms of this Agreement, consistent with the past practices of the parties even where all aspects regarding the provision of a particular Service is not described in detail.

1.4 Service Coordinators. Each of Seller and Company shall nominate a representative to act as the primary contact person with respect to the provision of the Services (each such person, a “Service Coordinator”); provided that Buyer Parent shall have the right to consent to the identity of the representative nominated by Company, such consent not be unreasonably withheld or delayed . The Service Coordinators shall be managerial-level employees of Company and Seller, as applicable. The initial Service Coordinators shall be Toyoki Furuta for Seller and a designee to be provided promptly after the Effective Date for Company, and each of their respective phone numbers, facsimile numbers and email addresses shall be set forth on an update made promptly after the Effective Date to Schedule 1 attached hereto. Each of Seller and Company may, in its sole discretion, change its Service Coordinator from time to time by providing written notice to the other party of such change and the relevant contact information for the new Service Coordinator at least three (3) Business Days prior to such change taking effect. Unless Seller and Company otherwise agree in writing, all communications relating to this Agreement or to the Services shall be directed to the Service Coordinators in accordance with Section 5.3 hereof. At Company’s Service Coordinator request, Seller’s Service Coordinator shall provide Company’s Service Coordinator with an estimate of Service Fees and Expenses for the Services.

1.5 Insurance. During the Transition Period, Seller shall maintain adequate insurance for the conduct of the Services in form and coverage consistent with Seller’s current coverage as of the Effective Date.

1.6 Subcontractors. Seller may subcontract any of its obligations under this Agreement to third-party service providers which have been approved by Company in writing (“Authorized Third Parties”), which approval shall not be unreasonably withheld or delayed. The Authorized Third Parties include those parties so identified in Exhibit A.

1.7 Consents. Seller shall use commercially reasonably efforts to obtain all material licenses, approvals and consents of any third party required by Seller to provide the Services (collectively “Required Consents”). If notwithstanding such commercial reasonable efforts, Seller is unable to provide any Service because of a failure to obtain such material licenses, approvals or consents, or Seller reasonably believes that performance of the Service would infringe or misappropriate a third party’s intellectual property rights, the parties shall cooperate to determine the best alternative approach.

1.8 Intellectual Property.

Subject to Company’s compliance with the terms and conditions of this Agreement, including payment of all Service Fees and Expenses, Seller hereby assigns and agrees to assign all of its right, title and interest in and to the Developed IP to Company.

(d) Seller will use commercially reasonable efforts to identify to Company any Patents owned by Seller and claiming Background Technology Seller expects to be embodied in Deliverables to be delivered to Company in connection with the provision of the Services under which Seller does not have the right to grant to company a license of the scope set forth in Section 1.8(b) without incurring an obligation to pay a royalty or other consideration to a third party.

1.9 Use of Services. Seller shall be required to provide, or cause its Affiliates to provide, Services only to Company and the Subsidiaries, and only in connection with the operation of Company and the Subsidiaries in existence as of the Closing Date. Company shall not, and shall not permit any of the Subsidiaries or any third parties under its control to, resell any Services to any Person whatsoever or permit the use of the Services by any Person other than in connection therewith.

1.10 Interruption of Transition Services. Subject to Section 5.14, Seller may cease or suspend providing, or have its Affiliates, Representatives or Authorized Third Parties cease or suspend providing, as applicable, the Services to Company and the Subsidiaries if and to the extent such cessation or suspension is (i) required by applicable Law, (ii) necessary due to regularly scheduled maintenance, alterations, repairs or replacements with respect to the applicable Services or the facilities used to provide such Services, (iii) necessary due to emergency maintenance, alterations, repairs or replacements with respect to the applicable Services or the facilities used to provide such Services, or (iv) necessary due to the temporary shutdown of the operation of the facilities providing any Service whenever Seller determines such action is necessary in the exercise of its reasonable judgment.

1.11 Cooperation. Company shall cooperate, and shall cause the Subsidiaries to cooperate, with Seller, its Affiliates, Representatives and Authorized Third Parties, and provide such Persons with such information and assistance as such Persons may reasonably require to enable them to provide the Services. Company shall allow, and shall cause the Subsidiaries to allow, such Persons and their respective employees, agents and sub-contractors reasonable access to its facilities as necessary for the performance of the Services.

1.12 Transitional Nature of Services. The parties acknowledge that the Services are transitional in nature and that Seller and its Affiliates may make changes from time to time in the manner in which the Services are performed if Seller (i) makes similar changes in the manner in which similar services are performed for its Affiliates and (ii) furnishes to Company substantially the same notice (in consent and timing) as Seller furnishes to its own Affiliates respecting such changes.

1.13 Consultation Period.

(a) The Service Coordinators shall collectively review, as promptly as reasonably practicable after the Effective Date, the Services listed on Exhibit A to determine if they properly reflect the Existing Services that are reasonably necessary, during the Transition Period, to support the operation of Company or the Subsidiaries as Company or such Subsidiary was operated in all material respects as of the Closing Date (“Needed Services”). In connection with such review, Company shall have the right to amend Exhibit A to add any Needed Services to Exhibit A at any time prior to the date that is forty-five (45) days after the Closing Date; provided that (a) the parties shall use reasonable efforts to complete such review and such amendment, if any, of Exhibit A, within the sixty (60) day period after the Effective Date (such period, the “Consultation Period”); and (b) Company shall not have a right to update Exhibit A with respect to adding any services relating to intellectual property matters. Notwithstanding the foregoing, no amendments to Exhibit A shall be made prior to Closing without Buyer Parent consent, such consent not to be unreasonably withheld or delayed.

(b) During the Consultation Period, the Service Coordinators shall discuss in good faith details with respect to the process of invoicing by Seller and its Affiliates for the Services pursuant to Section 4.2, including determining whether a monthly billing cycle is appropriate for the invoicing of specific Services.

(c) The parties hereby acknowledge and agree that the agreements set forth on Exhibit B hereto, as may be amended prior to the Closing Date as contemplated by this Section 1.13(c), shall survive the Closing and remain in effect in accordance with their terms. As soon as practicable after the Effective Date, the Service Coordinators shall collectively review and discuss whether any agreements (other than those listed on Exhibit B as of the Effective Date) between Seller or any of its Affiliates (not including Company and the Subsidiaries) on the one hand, and Company or any of the Subsidiaries on the other hand (any such agreement, an “Affiliate Agreement”), should survive the Closing. The Service Coordinators shall endeavor to make a recommendation to Seller and Buyer Parent with respect to the treatment of such Affiliate Agreements as soon as reasonably practicable but in any event no later than the expiration of the Consultation Period; provided that if there are Affiliate Agreements the treatment of which is not agreed to by the Service Coordinators, such Service Coordinators may make separate recommendations to be considered by Seller and Buyer Parent. Seller and Buyer Parent agree to promptly discuss such treatment in good faith based on the recommendations of the Service Coordinators with the intention of resolving any disagreements between them as soon as reasonably practicable. Without limiting the generality of the foregoing, the Service Coordinators shall make specific recommendations to Seller and Buyer Parent about (a) the survival of any provisions of the Affiliate Agreements addressing inventor compensation with respect to consideration received in connection with licenses granted under Patents which list as inventors any individuals who were employees or agents of Seller or any of its Affiliates (other than Company and the Subsidiaries) when the invention claimed in such Patent was conceived or reduced to practice and which Patents at any time are assigned to Buyer Parent or any of its Subsidiaries (including, without limitation, Company and the Subsidiaries) and/or (b) alternative provisions with respect to such inventor compensation to be adopted in lieu of causing such provisions of such Affiliate Agreements to survive. Seller and Buyer Parent shall not unreasonably withhold or delay agreement to the commercially reasonable recommendations of the Service Coordinators with respect to such inventor compensation issues. Any Affiliate Agreement that Seller and Buyer Parent mutually agree shall survive shall be included on Exhibit B and the parties agree to amend Exhibit B prior to the Closing Date to reflect any such agreement. Seller shall cause all Affiliate Agreements other than those included on Exhibit B (as may be amended prior to the Closing Date as contemplated by this Section 1.13(c)) to be terminated effective as of the Closing Date with no further obligations of the parties thereunder; provided that confidentiality and other matters that by the terms of such Affiliate Agreements survive termination shall so survive in accordance with such terms. Notwithstanding the foregoing, if Seller is not able to obtain the necessary consents to terminate any such Affiliate Agreement by the Closing Date, Seller shall not be in breach of this Agreement for failing to terminate such Affiliate Agreement to the extent it agrees to indemnify Company and the Subsidiaries for any Losses arising from and after the Closing Date under such Affiliate Agreement.

1.14 Excluded Services. Notwithstanding anything herein to the contrary, the following shall not be included as Services pursuant to this Agreement:

(a) Any services provided pursuant to any Affiliate Agreement listed on Exhibit B as of the Closing Date.

(b) Any services relating to intellectual property matters other than those listed on Exhibit A as of the Effective Date.

ARTICLE II

QUALITY OF SERVICES; LIMITATION OF LIABILITY; IMPROVEMENTS

2.1 Quality of Services.

(a) Seller shall perform the Services, or to cause the Services to be performed, in a workmanlike manner at the same general level of service, with the same degree of care (which in no event may be less than reasonable care), and in a manner similar in all material respects to the manner in which such Services have been provided by Seller and its Affiliates to Company and the Subsidiaries as of the Closing Date.

(b) In addition to the above and to the extent permitted by applicable Law, Seller agrees to pass through to Company and the Subsidiaries any warranties provided by Authorized Third Parties providing the Services.

(c) In the event of an alleged breach, default or nonperformance of any obligation under this Agreement by Seller or Company, the other party shall provide prompt written notice to the breaching party setting forth in reasonable detail the nature and extent of the alleged breach, default or nonperformance. The breaching party will then have a period of ten (10) Business Days in which to initiate actions reasonably designed to cure such alleged breach, default or nonperformance, and all such deficiencies shall, in any case, be cured within thirty (30) days following receipt by the breaching party of notice thereof.

2.2 Specific Performance. Seller acknowledges that the rights of Company to enforce the covenants and agreements made in this Agreement are special, unique, and of extraordinary character, and that, in the event Seller violates or fails or refuses to perform any covenant or agreement made by it herein, Company would be irreparably damaged and be without adequate remedy at law. Seller agrees, therefore, that, in the event it fails or refuses to perform, or otherwise violates, any covenant or agreement made by it herein, Company shall, in addition to any remedies available at law, be entitled to seek specific performance of such covenant(s) or agreement(s) and any other equitable remedy. For the avoidance of doubt, the foregoing shall not apply to the extent Company, its Affiliates, Representatives or Authorized Third Parties are expressly permitted to cease or suspend the provision of Services pursuant to Section 1,10 or otherwise not comply with other obligations hereunder pursuant to Section 5.14.

2.3 Limitation of Liability. IN NO EVENT SHALL SELLER, ITS AFFILIATES NOR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS, EMPLOYEES OR AGENTS (INCLUDING SELLER’S REPRESENTATIVES) BE LIABLE TO COMPANY OR ANY SUBSIDIARY FOR ANY INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE OR CONSEQUENTIAL DAMAGES OR FOR ANY LOSS OF PROFITS, LOSS OF REVENUE, LOSS RESULTING FROM INTERRUPTION OF BUSINESS OR LOSS OF DATA ARISING UNDER OR RELATING TO THIS AGREEMENT, WHETHER BASED ON BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE), OR OTHERWISE, AND WHETHER OR NOT SELLER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. EXCEPT IN THE CASE OF SELLER’S GROSS NEGLIGENCE, FRAUD OR WILLFUL MISCONDUCT, IN NO EVENT SHALL THE TOTAL LIABILITY OF SELLER, ITS AFFILIATES AND ANY OF ITS OR THEIR DIRECTORS, OFFICERS, EMPLOYEES AND AGENTS (INCLUDING SELLER’S REPRESENTATIVES) ARISING OUT OF OR RELATING IN ANY WAY TO THIS AGREEMENT EXCEED THE FEES PAID BY COMPANY TO SELLER HEREUNDER.

2.4 No Other Warranties. EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES EXPRESSLY STATED HEREIN, SELLER DISCLAIMS ALL EXPRESS AND IMPLIED REPRESENTATIONS AND WARRANTIES IN CONNECTION WITH THE SERVICES, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT.

2.5 Indemnification. In addition to Seller’s obligations set forth in Article IX of the Purchase Agreement, Seller shall indemnify, hold harmless and reimburse Company and the Subsidiaries for all Losses based upon, attributable to, arising out of or resulting from Seller’s gross negligence, fraud or willful misconduct in connection with the Services. Notwithstanding anything herein to the contrary, neither Seller, any of its Affiliates, nor any Representative shall be liable or held accountable, in damages or otherwise, for any error in judgment or any mistake of fact or Law or for anything which Seller does or refrains from doing, other than for Seller’s gross negligence, fraud or willful misconduct.

2.6 Mitigation. Company has a duty to mitigate (and cause the Subsidiaries to mitigate) the Losses that would otherwise be recoverable from Seller pursuant to this Agreement by taking appropriate and reasonable actions to reduce or limit the amount of any such Losses.

5.4 Disputes. In the event of any controversy or dispute arising out of or relating to this Agreement, the Service Coordinators shall in good faith attempt to resolve such dispute. If after 20 days the parties have not reached an agreement with respect to such dispute, either party may file a claim against the other party pursuant to Section 5.5 below.

5.5 Governing Law; Negotiation Procedure; Service of Process; Consent to Jurisdiction; Venue; Waiver of Jury Trial.

(a) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflicts of law rules.

(b) Negotiation Procedure; Service of Process.

(i) The parties intend that all disputes between the parties arising out of this Agreement shall be settled by the parties amicably through good faith discussions upon the written request of either party.

(ii) Prior to filing suit, instituting a Proceeding or seeking other judicial or governmental resolution in connection with any dispute between the parties or any of their subsidiaries arising out of this Agreement or any of the transactions contemplated hereby, the parties will attempt to resolve such dispute by good faith negotiations. Such negotiations shall proceed as follows:

(A) Any party may send a written notice to another party requesting such negotiations. Promptly following receipt of such notice by the receiving party, each party shall cause the individual designated by it as having general responsibility for this Agreement to meet in person with the individual so designated by the other party to discuss the dispute.

(B) If the dispute is not resolved within thirty (30) days after the first meeting between such individuals (or if earlier within forty five (45) days of the notice referred to in clause (i) above), then, upon the written request of any party, each party shall cause the individual designated by it as having general responsibility for the overall relationship defined by this Agreement to meet in person with the individual so designated by the other party to discuss the dispute.

(C) If the dispute is not resolved within fifteen (15) days after the first meeting between such individuals (or if earlier within thirty (30) days of the notice referred to in clause (ii) above), then, upon the written request of either party, Company shall nominate one corporate officer of the rank of senior vice president or higher, and Seller shall nominate one corporate officer of the rank of Board Director or higher, which corporate officers shall meet in person and attempt in good faith to negotiate a resolution to the dispute.

(iii) Except and only to the limited extent provided in Section 5.5(b)(iv), neither party shall file suit, institute a Proceeding or seek other judicial or governmental resolution of the dispute until at thirty (30) days after the first meeting between the corporate officers described in clause (iii) above (or if earlier forty five (45) days after the notice referred to in such clause (iii)) but after the expiration of such periods, either party may file suit, institute a Proceeding or seek other judicial or governmental resolution. For purposes of this Agreement, the procedures set forth in Section 5.5(b)(ii) and this Section 5.5(b)(iii) shall be referred to as the “Negotiation Procedures”.

(iv) Notwithstanding the provisions of Sections 5.5(b)(ii) and 5.5(b)(iii), any party may institute a Proceeding at any time seeking a preliminary injunction, temporary restraining order, or other equitable relief, if necessary in the sole judgment of that party to avoid material harm to its property, rights or other interests, before commencing, or at any time during the course of, the dispute procedure described in Sections 5.5(b)(ii) and 5.5(b)(iii). In addition, any party may file an action prior to the commencement of or at any time during or after the dispute resolution procedures in Sections 5.5(b)(ii) and 5.5(b)(iii) if in the sole judgment of that party it is necessary to prevent the expiration of a statute of limitations or filing period or the loss of any other substantive or procedural right.

(c) Consent to Jurisdiction; Venue. Each of the parties irrevocably and unconditionally submits to the exclusive jurisdiction of the Delaware Court of Chancery (and if jurisdiction in the Delaware Court of Chancery shall be unavailable, any Delaware State court and the Federal court of the United States of America sitting in the State of Delaware) for the purposes of any Action or other proceeding arising out of this Agreement or any transaction contemplated hereby (and agrees that no such Action or proceeding relating to this Agreement shall be brought by it or any of the Subsidiaries except in such courts). Each of the parties further agrees that, to the fullest extent permitted by applicable Law, service of any process, summons, notice or document by U.S. registered mail to such person’s respective address set forth in Section 5.3 above shall be effective service of process for any Action or proceeding in the State of Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each of the parties irrevocably and unconditionally waives (and agrees not to plead or claim), any objection to the laying of venue of any Action or proceeding arising out of this Agreement or the transactions contemplated hereby in the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, in any Delaware State court or the Federal court of the United States of America sitting in the State of Delaware) or that any such Action or proceeding brought in any such court has been brought in an inconvenient forum.

(d) Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT.

5.6 Books and Records; Inspection. Company shall, and shall cause the Subsidiaries to, make available on a timely basis to Seller and its Affiliates, Representatives and Authorized Third Parties such information and materials reasonably requested by Seller to enable such Persons to provide the Services. Company shall, and shall cause the Subsidiaries to, provide to such Persons reasonable access to the premises of Company and the other Subsidiaries, to the extent necessary for the purpose of providing the Services. During the Transition Period and for a period of three (3) years following the Transition Period or, if applicable Law requires a longer period, such longer period, Seller shall maintain a complete and accurate set of files, books and records of all business activities and operations conducted by Seller related to the Services provided under the terms of this Agreement, as well as any correspondence related to compliance with any applicable national, state and local laws, rules and regulations. Seller will provide Company, subject to Section 5.1 hereof, such information as Company may reasonably request from Seller’s books and records to the extent relating to the provision of any Service hereunder.

5.7 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other Governmental Entity to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such a determination, the parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.

5.8 Binding Effect; Benefit; Assignment.

(a) The provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns. No provision of this Agreement is intended to confer any rights, benefits, remedies, obligations or liabilities hereunder upon any Person other than the parties hereto and their respective successors and assigns.

(b) No party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the consent of each other party hereto, except that Company may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to one or more of its Affiliates at any time; provided that such transfer or assignment shall not relieve Company of any of its obligations hereunder.

5.9 Definitional and Interpretive Provisions. Section 1.2 of the Purchase Agreement shall also apply to this Agreement; provided, however, that for the purposes of this Agreement, “Business Days” shall mean a day, other than Saturday, Sunday or a public holiday in the country in which the applicable Service is performed.

5.10 Counterparts. This Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement shall become effective when each party hereto shall have received a counterpart hereof signed by the other party hereto. Until and unless each party has received a counterpart hereof signed by the other party hereto, this Agreement shall have no effect and no party shall have any right or obligation hereunder (whether by virtue of any other oral or written agreement or other communication).

5.11 No Third Party Beneficiaries. This Agreement is intended and agreed to be solely for the benefit of the parties, and no third party, other than the Subsidiaries, shall accrue any benefit, claim or right of any kind whatsoever pursuant to, under, by or through this Agreement.

5.12 Relationship of the Parties. It is expressly understood and agreed that in rendering the Services hereunder, each of the parties is acting as an independent contractor and that this Agreement does not make the providing party an employee, agent or other representative of the other party for any purpose whatsoever. Neither party has the right or authority to enter into any contract, warranty, guarantee or other undertaking in the name or for the account of the other party, or to assume or create any obligation or liability of any kind, express or implied, on behalf of the other party, or to bind the other party in any manner whatsoever, or to hold itself out as having any right, power or authority to create any such obligation or liability on behalf of the other party or to bind the other party in any manner whatsoever (except as to any actions taken by a party at the express written request and direction of the other party). No employee, contractor or subcontractor of any party shall be deemed to be an employee, contractor or subcontractor of the other party, it being fully understood and agreed that no employee of any party is entitled to benefits or compensation from the other party. Each party is wholly responsible for withholding and payment of all applicable national, state and local and other payroll taxes with respect to its own employees, including any contributions from them as required by Law.

5.13 Conflict. In case of conflict between the terms and conditions of this Agreement and any exhibit or schedule hereto, the terms and conditions of such exhibit or schedule shall control and govern, insofar as such terms and conditions in the exhibit or schedule relate to the Service that is the subject of such conflict. In the event of any conflict between the terms of the Purchase Agreement, on the one hand, and this Agreement and each exhibit or schedule hereto, on the other hand, the terms of this Agreement shall control and govern.

5.14 Force Majeure. Each party shall be excused from its obligations under this Agreement, other than payment obligations, to the extent that any delay or failure in the performance of such obligations is a result of any cause beyond its reasonable control (and without the fault of such party), including, acts of God, acts of civil or military authority, embargoes, epidemics, war, terrorism, riots, insurrections, fires, explosions, earthquakes, floods, severe weather conditions or changes in Law.

5.15 Termination of Purchase Agreement. This Agreement shall immediately terminate and be of no further force and effect upon any termination of the Purchase Agreement in accordance with the terms thereof.

5.16 Services Contingent on Closing. For the avoidance of doubt, Seller shall have no obligation to perform any of the Services pursuant to this Agreement unless and until Closing has occurred.
