 CONSIDERATION 
 Section 3.01. Purchase Price.

or U.S. Purchaser, as the case may be, of the Purchased Assets and the Shares, Purchaser shall assume the Assumed Liabilities and pay to Seller and/or the Selling Affiliate (as directed by Seller): 

(i) US$175,000,000 in cash at Closing (the “Closing Cash Consideration”, and, as adjusted pursuant to
Sections 3.02, 7.03(c), 9.08 and 10.14, the “Adjusted Closing Cash Consideration”); 
 (ii) an aggregate of US$135,900,000 in principal and interest payments pursuant to the U.S. Promissory Notes; 
 (iii) an aggregate of US$90,600,000 in principal and interest payments pursuant to the Japan Promissory Notes; 

  
 20 









 (iv) the amounts set forth in the Contingent Payment Agreement, upon the

 The Adjusted Closing Cash Consideration shall be paid by wire transfer of immediately available funds to an account

Seller to Purchaser as soon as practicable after the Closing, which statement will be prepared in accordance with Section 1060 of the Code. If Purchaser disagrees with the Allocation Statement provided by Seller and the parties are unable to
reach agreement, the matter will be resolved by an Independent Accounting Firm selected in the manner specified in Section 3.03(c). The decision of the Independent Accounting Firm as to the resolution of the dispute will be conclusive
and binding on the parties. The fees and expenses of the Independent Accounting Firm will be divided equally between Seller and Purchaser. Seller and Purchaser will file all Tax Returns (including Form 8594) on a basis that is consistent with the
Allocation Statement or the decision of the Independent Accounting Firm, as the case may be, and will take no position inconsistent therewith for Tax purposes unless required by an administrative or judicial determination.

or prior to the Closing Date that have been assumed by Purchaser or for which Purchaser is otherwise responsible shall be reflected as a liability on the Working Capital Estimate and the Closing Statement. 

  
 21 









 (C) Other Prorations. All prepayments, rents, current property or ad
valorem Taxes of the current year, salaries, assessments, utilities, maintenance charges and similar expenses associated with the Owned Properties or Real Property Leases shall be prorated between Seller and the Selling Affiliate (as applicable) on
the one hand, and Purchaser on the other hand, as of the Closing Date. To the extent such proration has not been effected by other means and to the extent of information then available, such proration shall be reflected on the Working Capital
Estimate and the Closing Statement. 
 (ii) “Target Working Capital” shall mean $0. 

(b) Working Capital Estimate. An estimate of the Working Capital Adjustment shall be calculated by Seller and set forth in an

Seller’s calculations, and Purchaser and its representatives shall have access to such records of Seller and the Selling Affiliate as may be reasonably requested for verifying and confirming such amounts and calculations. If the Working Capital
Adjustment set forth on the Working Capital Estimate is a positive number, such amount shall be added to the Closing Cash Consideration and paid by Purchaser to Seller and/or the Selling Affiliate on the Closing Date. If the Working Capital
Adjustment set forth on the Working Capital Estimate is a negative number, such amount shall be deducted from the Closing Cash Consideration. 
 Section 3.03. Post-Closing Purchase Price Adjustments. 
 (a) Closing
Statement. Within one hundred and twenty (120) calendar days after the Closing, Purchaser shall deliver to Seller a written statement (the “Closing Statement”) setting forth Purchaser’s calculation of (i) the
Working Capital Adjustment and (ii) the Net Accounts Receivables as of the point in time immediately prior to the Closing (the “Closing Net Accounts Receivable”). The Closing Statement shall contain information detailing the
basis for Purchaser’s calculations, and Seller and its representatives shall have access to such records of Purchaser as may be reasonably requested for verifying and confirming such amounts and calculations. Purchaser and Seller agree to be
reasonably available at each other’s request to meet and discuss the preparation of the Closing Statement. The “Final Closing Statement” shall be (i) the Closing Statement in the event that no Notice of Dispute with
respect thereto is delivered to Purchaser in accordance with Section 3.03(c) below or (ii) the Closing Statement as adjusted by (A) the agreement of Seller and Purchaser and/or the Independent Accounting Firm (defined below).
The “Final Working Capital Adjustment” shall be the Working Capital Adjustment set forth in the Final Closing Statement. The “Final Closing Net Accounts Receivable” shall be the Closing Net Accounts Receivable set
forth on the Final Closing Statement. 
 (b) Adjustments. 

(i) If the Working Capital Adjustment set forth on the Working Capital Estimate exceeds the Final Working Capital
Adjustment by more than US$50,000, then Seller shall pay to Purchaser the total amount of such excess, with interest as provided in 

  
 22 









 
Section 3.03(e), as an adjustment to the Initial Purchase Price, exclusive of any Transfer Taxes and without reduction for any withholding Taxes. If the Final Working Capital
Adjustment exceeds the Working Capital Adjustment set forth on the Working Capital Estimate by more than US$50,000, then Purchaser shall pay to Seller the total amount of such excess, with interest as provided in Section 3.03(e), as an
adjustment to the Initial Purchase Price, exclusive of any Transfer Taxes and without reduction for any withholding Taxes. 
 (ii) If the Target Net Accounts Receivable exceeds the Final Closing Net Accounts Receivable by more than US$50,000, then Seller shall pay to Purchaser the total amount of such excess, with interest as
provided in Section 3.03(e), as an adjustment to the Initial Purchase Price, exclusive of any Transfer Taxes and without reduction for any withholding Taxes. If the Final Closing Net Accounts Receivable exceeds the Target Net Accounts
Receivable by more than US$50,000, then Purchaser shall pay to Seller the total amount of such excess, with interest as provided in Section 3.03(e), as an adjustment to the Initial Purchase Price, exclusive of any Transfer Taxes and
without reduction for any withholding Taxes. 
 (iii) Any payment required to be made pursuant to this
Section 3.03(b) shall be made by wire transfer of immediately available funds to an account or accounts designated in writing by the receiving party for such purpose or by such other means as mutually agreed upon by the parties, in each
case, not later than the fifth Business Day after the date of the final determination of the Final Closing Statement. 
 (c)
Resolution of Objections. If Seller gives to Purchaser written notice of dispute (a “Notice of Dispute”) of any element of the Closing Statement within thirty (30) calendar days after receiving the Closing Statement, the
disputed amount shall be negotiated between Seller (for itself and/or on behalf of the Selling Affiliate, as applicable) and Purchaser. After the delivery by Seller to Purchaser of any such Notice of Dispute, Purchaser and Seller shall use their
reasonable best efforts to reconcile their differences with respect to any disputed amount, and any written resolution by them as to any disputed item set forth in the Notice of Dispute shall be final and binding on the parties hereto. If Purchaser
and Seller are unable to reach a resolution on all disputed items within thirty (30) calendar days after the delivery of the Notice of Dispute, either Purchaser or Seller may, by written notice, submit the items remaining in dispute for
resolution to an internationally recognized firm of independent public accountants reasonably acceptable to both Purchaser and Seller (the “Independent Accounting Firm”), whereupon each of Purchaser and Seller shall promptly furnish
to the Independent Accounting Firm such party’s final offer for the settlement of all items remaining in dispute (each a “Final Offer”). If Purchaser and Seller are unable to agree upon the selection of the Independent
Accounting Firm within thirty (30) calendar days after the delivery of the Notice of Dispute, then each party shall promptly thereafter designate one internationally recognized firm of independent public accountants. The parties shall cause
such firms promptly thereafter jointly to select a third firm to serve as the Independent Accounting Firm (which shall be an internationally recognized firm of independent public accountants that does not have a material business relationship with
either Seller or Purchaser or any of their respective Affiliates), and any such selection shall be binding on Purchaser and Seller with respect to resolving such disputed items. The Independent Accounting Firm shall resolve such disputed items in a
manner which is consistent with this 

  
 23 









 
Agreement but which shall not exceed the Final Offer of either Seller or Purchaser. All dispute resolution proceedings in connection with the Closing Statement or amount payable hereunder shall
take place at the offices of the Independent Accounting Firm in New York, New York or at such other location as Purchaser and Seller may otherwise mutually agree in writing. 
 (d) Independent Accounting Firm. Each of the parties shall furnish, at its own expense, the Independent Accounting Firm and the other parties hereto with such documents and other written
information as the Independent Accounting Firm may request in connection with resolving the disputed items. Each party may also furnish to the Independent Accounting Firm such other written information and documents as such party deems relevant;
provided, that copies of all such documents and materials shall be concurrently delivered to the other parties to the proceedings in the same form and manner as such materials are delivered to the Independent Accounting Firm. The Independent
Accounting Firm may, at their discretion, conduct one or more conferences with respect to the dispute between Purchaser and Seller, at which conference each party shall have the right to present such additional documents, materials and other
information and to be accompanied or represented by such advisors, counsel and accountants as each party shall choose in its sole discretion. Purchaser and Seller shall instruct the Independent Accounting Firm to render their written decision with
respect to all matters submitted to them by Purchaser and Seller as promptly as practicable. The Independent Accounting Firm shall determine the proportion of their fees and expenses to be paid by Purchaser and Seller, respectively, in accordance
with the relative merits of the parties’ positions. Purchaser and Seller shall promptly pay their respective shares of the fees and expenses of the Independent Accounting Firm. The determination of the Independent Accounting Firm as to all
disputed items shall be final and binding upon Purchaser and Seller, except in the case of manifest error or actual fraud. The disputed amount shall be payable by the party owing such amount within five (5) Business Days following resolution or
determination of the dispute. The failure of Seller to provide a Notice of Dispute within the thirty (30) calendar day time period referred to in Section 3.02(c) shall be deemed an acceptance by Seller of the Closing Statement.

 (e) Interest. Any amount owing hereunder with respect to the Final Closing Statement that is not paid within the
applicable time period set forth above shall bear interest on the amount due from the Closing Date to and including the date paid in full at an annual interest rate equal to the ninety (90)-day U.S. Treasury Bill rate in effect as of the Closing
Date (as reported in The Wall Street Journal). All such computations of interest shall be made by the party entitled to receive payment on the basis of a year of 360 days, in each case for the actual number of days occurring in the period for which
such interest is payable.

financial and operating data and other information in Seller’s possession relating to the Business as Purchaser may reasonably request; provided, however, that neither Purchaser nor any Purchaser Representative will have the right
to perform any investigative procedures that involve physical disturbance or damage to the real property of Seller or its Affiliates (including any environmental sampling or testing at such real property) or any of the other assets of the Business
without Seller’s prior written consent. Any investigation pursuant to this Section 7.03 shall be conducted in such manner as not to interfere unreasonably with the conduct of the business of Seller, the Selling Affiliate or any of
their respective Affiliates. 
 (b) Nothing in this Agreement will impose obligations on Seller, the Selling Affiliate or any of
their respective Affiliates to give Purchaser or any Purchaser Representative access to information if such access could reasonably be expected to cause Seller, the Selling Affiliate or any of their respective Affiliates to be in breach of any duty
of confidence or any other duty or obligation under applicable Law (including antitrust and Competition Laws and Laws affecting privacy, personal information and the collection, handling, storage, processing, use or disclosure of data);
provided, however, that Seller shall, and shall cause the Selling Affiliate and each of their respective controlled Affiliates to, (i) use reasonable efforts to obtain consent to disclose information covered by a confidentiality
agreement or other duty of confidence and (ii) disclose competitively sensitive information to the Purchaser’s external legal advisers pursuant to a common interest or joint defense agreement entered into by and between Seller and
Purchaser. 
 (c) Confirmation of Tantalum Inventory and Non-Tantalum Inventory. 

(i) During the week prior to the Closing, Seller shall provide Purchaser with a copy of the report relating to its most
recent physical inspection of the Business’s Tantalum Inventory and Non-Tantalum Inventory (including, for the avoidance of doubt, any Tantalum Inventory or Non-Tantalum Inventory of the Business contained in offsite storage facilities) and all
relevant documentation bringing the inventory levels set forth therein forward to (A) the date of such delivery and (B) the anticipated Closing Date (such Tantalum Inventory, the “Closing Tantalum Inventory”, and such
Non-Tantalum Inventory, the “Closing Non-Tantalum Inventory”). Such report shall (A) identify and quantify in a reasonable level of detail each subcategory comprising the definition of Minimum Tantalum Inventory and Minimum
Non-Tantalum Inventory, (B) identify on a “last-in, first-out” (LIFO) basis the amount of Excess Tantalum Inventory and Seller’s aggregate cost basis in such Excess Tantalum Inventory (the “Excess Tantalum Inventory
Value”) and (C) be accompanied by a certification of such Closing Tantalum Inventory, Closing Non-Tantalum Inventory and Excess Tantalum Inventory Value by an executive officer of Seller. 

  
 43 









 (ii) If the Closing Tantalum Inventory is less than the Minimum Tantalum
Inventory, then Seller shall, as soon as reasonably practicable but in no event later than six (6) months after the Closing Date, deliver to Purchaser an amount of Tantalum Inventory equal to: 

(A) in the case of a shortfall in tantalum ore, K2TaF7 and scrap, such shortfall from a source specified as “non-conflict”; and 

(B) in the case of a shortfall in any of (i) capacitor powder, work in progress and finished
goods, (ii) mill work in progress, finished goods and scrap or (iii) tantalum trays, such amount of tantalum ore,
K2TaF
7 and scrap from a source specified as “non-conflict” as is necessary for the Business to produce the
shortfall in the ordinary course, and Seller shall pay Purchaser an amount equal to the aggregate cost to the Business to produce such shortfall (calculated on the basis of the aggregate weighted average conversion cost per pound incurred by the
Business to produce each type of the shortfall in the three (3) months prior to the Closing Date) from the tantalum ore,
K2TaF
7 and scrap delivered by Seller. 

(iii) If the Closing Non-Tantalum Inventory is less than the Minimum Non-Tantalum Inventory, then Seller shall, within
five (5) Business Days after the Closing Date, pay to Purchaser by wire transfer of immediately available funds cash in an amount equal to such shortfall calculated by reference to book value in accordance with GAAP and on a basis consistent
with past practice. 
 Section 7.04. Restrictive Covenants. 

(a) Noncompetition. For a period of three (3) years from the Closing Date, Seller shall not, and Seller shall cause
Seller’s controlled Affiliates not to, directly or indirectly, without the prior written consent of Purchaser (i) produce, market, sell, lease or develop anywhere in the world any tantalum or niobium powder or fabricated products or alloys
having a principal component consisting of tantalum or niobium metal or any other metal powders suitable for use in capacitor anodes and sputtering targets, (ii) induce or attempt to induce any person, who is at Closing or has been at any time
within the twelve (12) months prior to Closing a supplier of goods or services to the Business, to cease to supply, or to restrict or vary the terms of supply, to the Business or (iii) do or say anything that is harmful to the reputation
of the Business or that could lead a Person to cease to deal with the Business on substantially equivalent terms to those previously offered or at all (the “Competitive Activities”). 

(b) Exceptions. Notwithstanding the foregoing, this Section 7.04 shall not be deemed breached as a result of the
ownership by Seller or any of its controlled Affiliates of: (i) less than ten percent (10%) of any class of stock of a Person engaged, directly or indirectly, in Competitive Activities; (ii) less than ten percent (10%) of the
aggregate value of all Indebtedness of a Person engaged, directly or indirectly, in Competitive Activities; or (iii) all or a portion of a Person that engages, directly or indirectly, in Competitive Activities if such Competitive Activities
account for less than ten percent (10%) of such Person’s consolidated annual revenues, provided that if, at the time of Seller’s or its controlled Affiliate’s acquisition of ownership of all or a portion of such a Person, such
Person derives ten percent (10%) or more of its consolidated 

  
 44 









 
annual revenues from Competitive Activities, then Seller or such Affiliate, as applicable, shall have twelve (12) months following such acquisition to cause to be divested a portion of such
Person’s business such that, immediately following such divestiture, Competitive Activities account for less than ten percent (10%) of such Person’s consolidated annual revenues, in which case this Section 7.04 shall not
be deemed breached by such ownership. 
 (c) Nonsolicitation. For a period of three (3) years from the Closing Date
(the “Non-solicitation Period”), Seller shall not, and shall cause Seller’s controlled Affiliates (including the Selling Affiliate) not to, directly or indirectly, without the prior written consent of Purchaser,
(i) solicit, influence, entice or encourage any Transferred Employee who received cash compensation from Seller or the Selling Affiliate or any other Affiliate of Seller in excess of $75,000 (or its equivalent) during 2010 or whose job title is
“manager”, “director” or equivalent to cease to curtail his or her relationship with Purchaser or any of its Affiliates or (ii) hire or attempt to hire, whether as an employee, consultant or otherwise, any such Transferred
Employee; provided, however, that (1) if any such Transferred Employee responds to any general public advertisement placed or general solicitation undertaken by Seller or the Selling Affiliate or any other Affiliate of Seller,
such advertisement or general solicitation shall not itself constitute a breach of this Section 7.04(c) and (2) this Section 7.04(c) shall not apply to any Transferred Employee whose employment is involuntarily
terminated by Purchaser or its Affiliates. 
 Section 7.05. Insurance. 

(a) From the date of this Agreement until the Closing, Seller shall ensure that all policies of insurance relating to the Business or any
of the Purchased Assets in force as of the date of this Agreement (the “Current Insurance Policies”) are kept in force. In the event that Seller shall become aware of any fact, event or circumstance (other than a fire or other
casualty loss, which Seller shall address in accordance with Section 7.05(b)) arising after the date of this Agreement and prior to the Closing in respect of which a claim may be made under the Current Insurance Policies, Seller shall
(i) file a claim in respect of such event or circumstance and (ii) have such claim paid prior to the Closing. In the event that such a claim is not paid prior to the Closing, Seller shall pursue payment in respect of such a claim on behalf
of Purchaser and Purchaser shall have the right to receive any payment made in respect of any such claim made prior to the Closing as, when and to the extent such claim is paid. 

(b) In the event any Purchased Asset that is a tangible asset is destroyed or damaged, in whole or in part, by fire or other casualty
prior to the Closing, then in lieu of making a claim in accordance with Section 7.05(a), Seller may repair or replace (with similar grade and quality) such damaged asset before the Closing Date and such repaired or replaced asset shall
constitute a Purchased Asset, in which case Purchaser shall not have any right, claim or title to any insurance proceeds relating to such asset. 

  
 45 









 Section 7.06. Real Property. From and after the date hereof, Seller shall, and shall
cause the Selling Affiliate to, use commercially reasonable efforts to assist Purchaser in obtaining, at or prior to Closing:

Property located in the United States (or an equivalent form of title assurance in accordance with local custom reasonably satisfactory to Purchaser for each parcel of Owned Property located outside the United States) issued by a title insurance
company satisfactory to Purchaser (the “Title Company”), together with the documents referenced therein (the “Title Commitments”), and (ii) title insurance policies (which may be in the form of a mark-up of a
pro forma of the Title Commitments) in accordance with the Title Commitments, insuring the Seller’s or the Selling Affiliate’s fee simple title to each Owned Property as of the Closing Date, with gap coverage from the named owner through
the date of recording, in such amount as Purchaser reasonably determines to be the value of the property insured thereunder (the “Title Policies”), and including in each case an extended coverage endorsement insuring over the
general or standard exceptions, ALTA Form 3.1 zoning (with parking and loading docks) and all other endorsements reasonably requested by Purchaser, in form and substance reasonably satisfactory to Purchaser; 

(b) a survey for each Owned Property, dated no earlier than the date of this Agreement, prepared by a licensed surveyor satisfactory to
Purchaser and conforming to 1999 ALTA/ACSM Minimum Detail Requirements for Urban Land Title Surveys, and certified to Purchaser and the Title Company, in a form reasonably satisfactory to each of such parties (the “Surveys”); and

 (c) a written consent (in form and substance reasonably satisfactory to Purchaser) for the transfer of each Real Property
Lease from the landlord or other party whose consent thereto is required under such Real Property Lease (the “Lease Consents”). 
 Purchaser and Seller shall bear all fees, costs and expenses equally with respect to obtaining the Title Commitments and Title Policies, including costs of removal of exceptions to the Title Policies.

 Section 7.07. ITAR. Seller shall notify the Directorate of Defense Trade Controls (the “DDTC”) by
registered mail at least 60 (sixty) days prior to the Closing of the intended sale in accordance with Section 122.4(b) of the International Traffic in Arms Regulations, 22 .C.F.R. 120-130 (“ITAR”) and within 5 (five) days after
the Closing of the change in ownership in accordance with Section 122.4(a) of ITAR unless any of these notice requirements have been waived in writing by the DDTC. The Parties hereby acknowledge and agree to cooperate in good faith in
addressing any concerns that DDTC may raise in connection with this Agreement and to use their respective reasonable best efforts to assure that Purchaser obtains a new ITAR registration. 

Section 7.08. Confidentiality. From and after the Closing Date, for a period of three (3) years after the Closing Date,
Seller agrees and agrees to cause the Selling Affiliate, to treat all confidential data, reports, records, processes, know-how and other information it has developed or has in its control or possession relating to the Business, whether or not marked
as confidential or proprietary (the “Information”), as confidential and to not disclose, discuss or reveal such Information to a third party without the prior written consent of Purchaser, unless Seller or the Selling Affiliate are
required by applicable Law or order of a Government Authority to disclose any such Information and Seller or Selling Affiliate have informed Purchaser of such requirement and given Purchaser a reasonable opportunity to contest such requirement or to
seek 

  
 46 









 
a protective order or a stay of such disclosure order. Seller agrees to exercise all reasonable efforts to avoid the disclosure of such Information to any third party. The obligations in this
Section 7.08 shall not apply to any portion of the Information: 
 (a) which is or becomes, through no act or
failure on Seller’s or the Selling Affiliate’s part, published information known on a non-confidential basis; or 

(b) which corresponds in substance to information hereafter furnished to Seller or the Selling Affiliate by others as a matter of right
without restriction on disclosure; or 
 (c) which is independently developed by or on behalf of Seller or the Selling
Affiliate, without knowledge of the Information. 
 Section 7.09. Remediation Activities. 

(a) Except as set forth in Section 7.09(b), from and after the Closing, Seller shall control all remedial actions and all
negotiations with any Governmental Authority or any other Person in respect to all Environmental Claims that are subject to Seller’s indemnification obligations under Section 12.03 with counsel, consultants or contractors selected
by Seller (to be reasonably acceptable to Purchaser), provided that Seller shall (i) keep Purchaser reasonably informed as to the status of the foregoing, (ii) promptly provide Purchaser with any material non-privileged related
information, documentation and correspondence, and (iii) exercise reasonable best efforts to consult with Purchaser prior to exchanges of material information or material negotiations with any Person (Purchaser to make itself reasonably
available and without unreasonable delay as to same). Such remedial actions and negotiations shall be performed in a commercially reasonable manner, including, to the extent allowed or authorized by applicable Environmental Law or the Governmental
Authority having jurisdiction over a remedial action, the use of applicable commercial and/or industrial remediation standards and institutional controls. Seller agrees that, in conducting any remedial action or seeking a particular remedy or agreed
remediation standard, it shall not unreasonably interfere with Purchaser’s business operations. Notwithstanding anything to the contrary contained herein, Seller shall not enter into any settlement or judgment, without Purchaser’s prior
written consent, such consent not to be unreasonably withheld, that would encumber or impose on the Business or the Purchased Assets any restriction or condition that would materially and adversely affect the Purchaser or the Business. Purchaser may
comment on Seller’s proposed remedial actions and may participate at its expense in any meetings or discussions with relevant Governmental Authorities, but Purchaser shall have no right to perform or participate in any aspect of any remedial
actions performed or directed by Seller; provided, however, that Purchaser shall provide reasonable access to Seller and its environmental consultants to any property within the control of Purchaser that is subject to any remedial
action obligation of Seller under this Agreement. 
 (b) Notwithstanding anything in Section 7.09(a), from and after
the Closing, Purchaser shall control all remediation actions and all negotiations with any Governmental Authority or any other Person in respect to those Special Environmental Liabilities set forth on Schedule 7.09(b). For so long as Seller
is required to indemnify Purchaser and the Purchaser Indemnified Parties for such Liabilities, Seller shall reimburse Purchaser for the reasonable costs associated with continued implementation of such remedial program within 60 days of receipt of


  
 47 









 
invoices for any remedial work relating thereto. Any material changes to the existing remedial program relating to such Liabilities must be approved in writing by Seller, which approval may not
be unreasonably withheld, conditioned or delayed. Purchaser shall provide copies of relevant non-privileged reports and submissions to Seller regarding such remediation activities. 

(c) Upon completion of a remediation required under this Agreement, as evidenced by: (i) a “no further remediation”
letter, or the substantial equivalent, in form and substance reasonably acceptable to Purchaser, from the Governmental Authority having jurisdiction over the location where the remediation has occurred; (ii) written confirmation, in form
and substance reasonably acceptable to Purchaser, from the Governmental Authority exercising authority over Seller’s remediation work, that the underlying conditions have been remedied; or (iii) written confirmation, in form and substance
reasonably acceptable to Purchaser, from the relevant Person under any remediation agreement between Seller and/or Purchaser and the relevant Person, that the underlying conditions have been remedied, then Seller shall be forever released and
discharged by Purchaser and all Purchaser Indemnified Parties from any further related remediation under this Agreement. In any event, Seller’s remediation obligations with respect to the Special Environmental Liabilities shall cease at the
termination of the indemnity period set forth in Section 12.06(g).

its Affiliates and the Business. Purchaser acknowledges that Seller and its Affiliates could be irreparably damaged if any trade secrets or other information that is confidential, non-public or proprietary to Seller or any of its Affiliates that
does not relate to the Business (the “Seller Information”) was disclosed by Purchaser, its Affiliates or any Purchaser Representative to any Person and, from and after the Closing Date, for a period of three (3) years after the
Closing Date, Purchaser will not, and will cause its Affiliates and each Purchaser Representative not to, at any time, without the prior written consent of Seller, disclose or use (or permit to be disclosed or used) in any way any such Seller
Information (regardless of whether such Seller Information was obtained during the course of pursuing the transactions contemplated by this Agreement or following the Closing from a Transferred Employee), unless such Seller Information (i) was
already in Purchaser’s possession prior to Purchaser’s entry into the Confidentiality Agreement; provided that such Seller 

  
 48 









 
Information is not known by Purchaser to be subject to another confidentiality agreement with or other obligation of secrecy to Seller or another party, (ii) becomes generally available to
the public other than as a result of a disclosure by Purchaser, its Affiliates or any Purchaser Representative, or (iii) becomes available to Purchaser on a non-confidential basis from a source other than Seller, its Affiliates or any of their

representatives reasonable access (with an opportunity to make copies), during normal business hours and upon reasonable notice, to Purchaser’s and Purchaser’s Affiliates properties, books, work papers, Contracts, personnel and records
(whether in hard copy or computer format) relating to the Business as Seller shall reasonably request in order to comply with any applicable Laws; provided, however, that any such access by Seller shall not unreasonably interfere with
the conduct of the Business by Purchaser. Seller shall promptly reimburse Purchaser for any and all out-of-pocket costs and expenses (excluding reimbursement for general overhead, salaries and employee benefits) actually incurred by Purchaser, any
Affiliate of Purchaser or any Purchaser Representative in connection with the foregoing. 
 Section 8.03. No Contacts with
Certain Third Parties. From the date of this Agreement until the Closing, without Seller’s prior written consent (which consent may not be unreasonably withheld, conditioned or delayed), Purchaser shall not, and Purchaser shall cause all of
its Affiliates and Purchaser’s Representatives not to, contact or communicate with any employees, consultants, landlords, customers, suppliers, licensors or distributors of Seller, any of Seller’s Affiliates and/or the Business in
connection with the transactions contemplated by this Agreement.

Return.

 Section 9.01. Reasonable Best Efforts; Further Assurances. 
 (a) Purchaser
and Seller shall cooperate and use their reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary or desirable 

  
 49 









 
to fulfill the conditions precedent to the other party’s obligations and otherwise to consummate the transactions contemplated by this Agreement. Seller and Purchaser shall, and Seller shall
cause the Selling Affiliate and the Company to, execute and deliver such other documents, certificates, agreements and other writings and take such other actions as may be necessary or desirable under applicable Law in order to consummate or
implement expeditiously the transactions contemplated by this Agreement. 
 (b) Without limiting the generality of the
foregoing, Seller and Purchaser shall cooperate with one another (i) in determining whether any authorizations, actions, consents, approvals or waivers are required to be obtained from, or notices given to, parties to any material third-party
(non-Affiliate) Contracts in connection with the transactions contemplated by this Agreement and (ii) in taking such commercially reasonable actions to obtain any such authorizations, actions, consents, approvals or waivers and to timely give
any such notices, in each case, that are material to the operation of the Business. Purchaser shall be responsible for any expenses associated with obtaining any such authorizations, actions, consents, approvals or waivers, or the giving of any such
notices, and none of the Seller, the Company or the Selling Affiliate will have any Liability for the failure to obtain any such authorization, action, consent, approval or waiver or to give any such notice. For the avoidance of doubt, Purchaser
shall be responsible for payment of the filing fee, but each of Purchaser and Seller shall be responsible for any associated costs, including legal costs, relating to filing and obtaining consent, approval or waiver under the HSR Act. 

Section 9.02. Governmental Authorities and Other Proceedings. 

(a) General. Seller and Purchaser shall cooperate with one another in (i) determining whether any action in respect of

reissuance of any Permit), (ii) taking any such actions (including making any filing or furnishing any information required in connection therewith) in order to obtain any such consent, approval or waiver on a timely basis and
(iii) keeping the other party promptly informed in all material respects with respect to any communication given or received in connection with any such action, consent, approval or waiver, including providing to each other in advance any
analyses, appearances, presentations, memoranda, briefs, arguments, opinions and proposals made or submitted to a Governmental Authority by or on behalf of any party. 
 (b) Certain Filings. Each of Purchaser and Seller agrees to make all appropriate filings required by the HSR Act and any Competition Laws with respect to the transactions contemplated hereby as
promptly as practicable and to supply as promptly as practicable any additional information and documentary material that may be requested pursuant to the HSR Act or any Competition Laws. Neither Purchaser nor Seller shall agree to any voluntary
extension or delay of any statutory waiting period or withdraw its Notification and Report Form pursuant to the HSR Act unless such party first consults and reasonably considers the views of each other party hereto. No party hereto shall participate
in any meeting with any Governmental Authority with respect to the HSR Act or any Competition Law as they relate to the transactions contemplated hereby (except in the case of Purchaser for any meetings between Purchaser and any Governmental
Authority to discuss possible remedies), unless it consults with the other parties hereto in advance and, to the extent permitted by such Governmental Authority, gives such other parties the opportunity to attend and participate thereat. 


  
 50 









 (c) Purchaser’s Efforts. Without limiting the provisions set forth in paragraphs
(a) and (b) above, Purchaser shall use commercially reasonable efforts to obtain any consent, approval or waiver relating to the HSR Act or any Competition Law that is required for the consummation of the transactions contemplated by this
Agreement. For the avoidance of doubt, if any administrative or judicial action or proceeding is instituted (or threatened to be instituted) challenging the transactions contemplated by this Agreement as violative of any Competition Law, or if any
judgment or Law is enacted, entered, promulgated or enforced by a Governmental Authority that would make such transactions illegal or would otherwise prohibit or materially impair or delay the consummation of such transactions, Purchaser shall use
commercially reasonable efforts to contest and resist in good faith any such action or proceeding and shall use commercially reasonable efforts to have vacated, lifted, reversed or overturned any judgment, whether temporary, preliminary or
permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by this Agreement. Notwithstanding anything to the contrary contained in this Agreement, neither Purchaser nor its Affiliates shall
be required to take any action that (i) involves divestiture of an existing business or any material assets of Purchaser or its Affiliates, including, after the Closing, the Business or any Purchased Assets, (ii) involves unreasonable
expense, (iii) could reasonably be expected to materially impair the overall benefit expected to be realized from the consummation of the transactions contemplated by this Agreement or (iv) involves behavioral commitments or limits
Purchaser’s rights of ownership in any of its or its Affiliates’ assets, or after the Closing, the Purchased Assets or any assets of the Business. 
 Section 9.03. Public Announcements. From the date of this Agreement through the Closing Date, each of Seller and Purchaser must obtain the prior written consent of the other party before issuing

such offer is made. Such U.S. Business Employees who accept such offer and commence employment with Purchaser are referred to herein as the “U.S. Transferred Employees.” Nothing in this Article X shall entitle any U.S.

 (b) Purchaser shall honor the terms and conditions of the applicable Collective Bargaining Agreement and shall bargain in good faith with the applicable union in accordance with all applicable Laws. The
employment of each Union Employee who becomes a U.S. Transferred Employee shall continue with Purchaser immediately following the Closing under the terms and conditions of the applicable Collective Bargaining Agreement. The provisions set forth in
Sections 10.02(a), 10.03, 10.04, 10.05, and 10.08 shall not apply to a U.S. Transferred Employee who is a Union Employee.

benefit plans, employee retirement plans, vacation, disability, severance and other employee benefit and incentive plans or policies (the “Purchaser’s Plans”). Purchaser shall, or shall cause an Affiliate to, waive any
pre-existing 

  
 53 









 
condition limitations and eligibility waiting periods under the Purchaser’s Plans (but only to the extent such pre-existing condition limitations and eligibility waiting periods were
satisfied under the Employee Plans as of the Closing Date) and shall recognize (or cause to be recognized) the dollar amount of all expenses incurred by each U.S. Transferred Employee and his or her spouse and dependents during 2011 for purposes of
satisfying the deductibles and co-payment or out-of-pocket limitations for such calendar year under the relevant Purchaser’s Plans.

through Closing.

“continuation coverage” benefits provided after the Closing for all U.S. Transferred Employees and “qualified beneficiaries” of U.S. Transferred Employees for whom a “qualifying event” occurs on or after the Closing

Section 4980B of the Code and Sections 601-608 of ERISA. Seller shall retain all obligations to provide continuation coverage relating to qualifying events occurring prior to the Closing Date. 

Section 10.07. Workers’ Compensation. Seller or the Selling Affiliate, as applicable, shall retain the obligation and
Liability for any workers’ compensation, occupational disease or illness, or similar workers’ protection claims with respect to each Business Employee related to events occurring prior to the Closing Date regardless of when filed.

Closing Date. 
 Section 10.08. Retirement Savings Plan. Effective as of the Closing Date, the active
participation of each U.S. Transferred Employee in the Cabot Retirement Savings Plan shall cease. Effective as of the Closing Date or any subsequent date reasonably requested by Purchaser (but not later than the 60th day following the Closing Date), U.S. Transferred Employees shall be
eligible to effect a “direct rollover” (as described in Section 401(a)(31) of the Code) of their account balances under the Cabot Retirement Savings Plan to a U.S. tax-qualified defined contribution plan of Purchaser or its Affiliates
(“Purchaser DC Plan”) in the form of cash. Seller and Purchaser shall take all actions necessary to permit such rollovers as soon as practicable after the Closing Date, including, without limitation, amendment of the Purchaser DC

 54 









 
Affiliates shall succeed to and assume each Retention Agreement with a Transferred Employee and all of the obligations and Liabilities of Seller thereunder for the Retention Incentives and
Severance Payments described in the Retention Agreements. 
 Section 10.10. Severance Obligations. Effective as of the
Closing, Purchaser or one of its Affiliates shall succeed to and assume all of the obligations and Liabilities of Seller and its respective Affiliates arising on or after the Closing Date for the payment or provision of any severance payments to be

Obligations”). 
 Section 10.11. Unvested Amounts. Seller shall take all necessary action to vest the U.S.

 Section 10.12. WARN Act. Purchaser shall indemnify Seller for any
Liability arising under the WARN Act or similar applicable Law arising after the Closing Date with respect to employees of the Business whose employment was terminated prior to the Closing Date; provided, however, that Purchaser shall
not indemnify Seller for any Liability arising under the WARN Act which is incurred by Seller’s own actions prior to the Closing Date without regard to any post-Closing actions of Purchaser. Seller shall provide Purchaser with a list of
employees who performed services with respect to the Business whose employment was terminated 90 days prior to the Closing Date. 
 Section 10.13. Employee Communications. Seller and Purchaser shall cooperate in communications with U.S. Transferred Employees with respect to employee benefit plans maintained by Seller or
Purchaser and with respect to other matters arising in connection with the transactions contemplated by this Agreement; provided, however, that from and after the Closing, nothing herein will restrict in any manner Purchaser’s
communications with any U.S. Transferred Employees. 
 Section 10.14. Japanese Defined Benefit Plan and Directors’
Plan. 
 (a) As soon as practicable after the Closing but no later than twelve (12) months from the Closing, Purchaser
shall cause the Company to establish a defined benefit plan (the “Company Benefit Plan”) for the benefit of the Company’s employees transferred from the Selling Affiliate to the Company pursuant to the Corporate Split Agreement
(“Japanese Transferred Employees”). The terms and conditions of the Company Benefit Plan shall be consistent with the terms and conditions of the defined benefit plan that is presently sponsored by the Selling Affiliate and other
Seller Affiliates in Japan (the “Japanese Benefit Plan”) as of the Closing. For avoidance of doubt, the Japanese Benefit Plan consists of the Employees’ Retirement Plan for Cabot Group. 

(b) Purchaser shall cause the Company to become a co-sponsor in the Japanese Benefit Plan as of the Closing and remain such co-sponsor
until the date the Company Benefit 

  
 55 









 
Plan is established (the “DB Transfer Date”) in order that the Japanese Transferred Employees may remain participants under the Japanese Benefit Plan until the DB Transfer Date.
The sole financial obligation of the Company during its period of co-sponsorship shall be to pay for the required employer contributions to the fund for benefits earned during the period beginning on the Closing Date and ending on the DB Transfer
Date in relation to the Japanese Transferred Employees. The accrued liability in the Japanese Benefit Plan for the Japanese Transferred Employees as of the DB Transfer Date shall be assumed in the Company Benefit Plan from and after the DB Transfer
Date. Seller and Purchaser shall direct Mizuho Trust Bank, as operating agent, to determine the ratio of actuarial obligations (Suri-Saimu) for the Japanese Transferred Employees to other subject employees in the Japanese Benefit Plan as of
the Closing (the “Ratio”). Purchaser shall have the Company, and Seller shall have the Selling Affiliate and its other Affiliates in Japan, split funded assets in the Japanese Benefit Plan into the Company Benefit Plan and the
Japanese Benefit Plan as of the DB Transfer Date based on the Ratio. 
 (c) Seller shall instruct Towers Watson (the
“Seller Actuary”) to determine the Underfunded Pension Amount as of the DB Transfer Date. The “Underfunded Pension Amount” shall be the projected benefit obligation for the Japanese Transferred Employees as of the
DB Transfer Date minus the fair value of the funded assets of the Japanese Benefit Plan as valued by the administrator of such plans as at the date of this Agreement (being Mizuho Trust Bank) for the Japanese Transferred Employees at
the DB Transfer Date. With the exception of the discount rate, all actuarial valuation assumptions shall be the same as were used in the most recently completed actuarial valuation for year-end disclosure purposes under GAAP. The discount rate used
in the most recently completed actuarial valuation for year-end disclosure purposes under GAAP shall be adjusted with any movement in the yield on Japanese government 10-year bonds between the valuation date and the month end preceding the DB
Transfer Date. Each of the parties shall furnish, at its own expense, the Seller Actuary with such documents and other written information as the Seller Actuary may request in connection with determining the Underfunded Pension Amount (including
without limitation the funded status of plans, cash flow, plan asset information, amortization amounts during the relevant period on which the valuation is based, plan provisions, membership data and asset information) and the chief financial
officer of the party furnishing such information shall certify that such information is accurate and complete in all material respects as at the date of furnishing such information or the date otherwise expressly certified therein. The fees and
expenses of the Seller Actuary will be borne by Seller. 
 (d) Seller shall instruct the Seller Actuary to deliver a certificate
(the “Actuary Certificate”) to Seller and Purchaser setting forth its determination of the Underfunded Pension Amount, together with the actuarial valuation report, actuarial assumptions and methods and supporting documentation, as
promptly as practicable after the DB Transfer Date. Purchaser may appoint its own actuary (the “Purchaser Actuary”) to review the Seller Actuary’s calculations. Purchaser shall have ten (10) Business Days to review the
Seller Actuary’s calculations and respond in writing with any questions regarding the calculations. To the extent the Seller Actuary and the Purchaser Actuary cannot agree on a final Underfunded Pension Amount, a third party independent actuary
(the “Third Party Actuary”) shall be jointly appointed by Purchaser and Seller, the findings of whom shall be binding on both parties and the cost of whom shall be borne equally by Purchaser and Seller. Within ten (10) days
after finalization of the Underfunded Pension Amount, Seller shall pay to Purchaser such Underfunded Pension Amount. 

  
 56 









 (e) At Closing, Seller will pay all obligations under the Cabot Supermetals Directors’
Retirement Plan and any other retirement plan relating to the Japanese Transferred Employees other than the Employees’ Retirement Plan for Cabot Group. 
 Section 10.15. Cooperation. 
 (a) Each of Purchaser and Seller recognize it
to be in the best interests of the parties hereto and their respective employees that the transactions in this Article X be effected in an orderly manner and agree to devote their respective reasonable best efforts and to cooperate fully in
complying with the provisions of this Article X. Without limiting the generality of the foregoing, each of the parties agree to execute, deliver and file all documents and to take all such actions as are reasonably necessary or desirable in
order to carry out and perform the purposes of this Article X and to facilitate the transactions referred to in this Article X. 
 (b) Without limiting the generality of Section 10.14(a), Seller shall use its commercially reasonable efforts to cooperate with Purchaser promptly at its request for up to 90 days following
the Closing Date in endeavoring to obtain the consent of any significant contractors of the Business immediately prior to Closing to have the Purchaser (or its Affiliates) engage such contractors in the Business from and after Closing. 

Section 10.16. No Third Party Beneficiary or Employee Rights. Nothing in this Article X expressed or implied shall
(a) create any third-party beneficiary or other rights in any employee or former employee (including any beneficiary or dependent thereof) of Seller, the Company or the Selling Affiliate or any other Person other than the parties hereto and
their respective successors and permitted assigns, (b) constitute or create an employment agreement or (c) constitute or be deemed to constitute an amendment to any employee benefit plan sponsored or maintained by Seller, the Selling
Affiliate, the Company, Purchaser or any of Purchaser’s Affiliates.

(b) The covenants and agreements of the parties hereto contained in this Agreement shall survive in accordance with their respective
terms. 

  
 59 









 Section 12.02. Indemnification by Purchaser. From and after the Closing, Purchaser
hereby agrees to indemnify, defend and hold harmless Seller, the Selling Affiliate, their respective Affiliates and, if applicable, their respective directors, officers, stockholders, partners, attorneys, accountants, agents, employees, heirs,
successors and assigns (the “Seller Indemnified Parties”) from, against and in respect of any Losses actually incurred by any of the Seller Indemnified Parties resulting from or arising out of (a) any breach of any
representation or warranty made by Purchaser contained in this Agreement, (b) the breach of any covenant or agreement of Purchaser contained in this Agreement, (c) any Assumed Liability or (d) the conduct of the Business or the
ownership or use of the Purchased Assets after the Closing Date. The Seller Indemnified Parties shall not be entitled to assert any indemnification claim pursuant to clause (a) of this Section 12.02 (i.e., with respect to any breach
of any representation or warranty made by Purchaser contained in this Agreement) after the expiration of the applicable survival period set forth in Section 12.01(a) (except to the extent provided therein) and, in each such case, any
such claim shall be irrevocably and unconditionally released and waived by the Seller Indemnified Parties upon such expiration, whether or not a longer period would be permitted by applicable Law. 

Section 12.03. Indemnification by Seller. From and after the Closing, Seller hereby agrees to indemnify, defend and hold harmless
Purchaser, its Affiliates and, if applicable, their respective directors, officers, stockholders, partners, attorneys, accountants, agents, employees, heirs, successors and assigns (the “Purchaser Indemnified Parties” and,
collectively with the Seller Indemnified Parties, the “Indemnified Parties”) from, against and in respect of any Losses actually incurred by any of the Purchaser Indemnified Parties resulting from or arising out of (a) any
breach of any representation or warranty made by Seller contained in this Agreement, (b) the breach of any covenant or agreement of Seller contained in this Agreement, (c) any Excluded Liability or Excluded Asset, or (d) any Special

Section 12.01(a) (except to the extent provided therein) and, in each such case, any such claim shall be irrevocably and unconditionally released and waived by the Purchaser Indemnified Parties upon such expiration, whether or not a

 Section 12.04. Indemnification Procedures. 

(a) With respect to third party claims, all claims for indemnification by any Indemnified Party hereunder shall be asserted and resolved
as set forth in this Section 12.04. 
 (b) In the event that any written claim or demand for which Seller or
Purchaser, as the case may be (an “Indemnifying Party”), may be liable to any Indemnified Party hereunder (after giving effect to the limitations set forth in this Article XII) is asserted against or sought to be collected
from any Indemnified Party by a third party, such Indemnified Party shall promptly, but in no event more than thirty (30) days following such Indemnified Party’s receipt of such 

  
 60 









 
claim or demand, notify the Indemnifying Party of such claim or demand in reasonable detail (taking into account the information then available to the Indemnified Party) and the amount or the
estimated amount thereof to the extent then feasible (the “Claim Notice”). The Indemnifying Party shall have thirty (30) days from receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified
Party (i) whether or not the Indemnifying Party disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such claim or demand and (ii) whether or not the Indemnifying Party elects to defend the
Indemnified Party against such claim or demand. All costs and expenses incurred by the Indemnifying Party in defending such claim or demand shall be a liability of, and shall be paid by, the Indemnifying Party; provided, however, that
the amount of such costs and expenses that shall be a liability of the Indemnifying Party hereunder shall be subject to the limitations set forth in Section 12.06 and shall otherwise constitute Losses hereunder. 

(c) Except as hereinafter provided, in the event that the Indemnifying Party notifies the Indemnified Party of its election to defend
against such claim or demand, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the sole power to direct and control such defense. The Indemnifying Party shall promptly inform the
Indemnified Party upon request of the status of any claim. If any Indemnified Party desires to participate in any such defense, it may do so at its sole cost and expense, and the Indemnifying Party will not be liable to the Indemnified Party for
legal expenses incurred by the Indemnified Party in connection with the defense thereof. 
 (d) The Indemnified Party shall not
settle a claim or demand for which it is indemnified by the Indemnifying Party without the written consent of the Indemnifying Party. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle, compromise or
offer to settle or compromise any such claim or demand on a basis that would have a continuing effect in any material respect on the Indemnified Party or any Affiliate thereof or any of their respective businesses, assets or operations. 

(e) If the Indemnifying Party elects not to defend the Indemnified Party against such claim or demand, whether by failing to give the
Indemnified Party timely notice as provided above or otherwise, then the amount of any such claim or demand, or, if the same be contested by the Indemnified Party, then that portion thereof as to which such defense is unsuccessful (including the
reasonable costs and expenses pertaining to such defense) shall be the liability of the Indemnifying Party and shall constitute Losses hereunder, subject to the limitations set forth in Section 12.06. 

(f) To the extent the Indemnifying Party shall direct, control or participate in the defense or settlement of any third party claim or
demand, the Indemnified Party will provide the Indemnifying Party and its counsel access to, during normal business hours, relevant business records and other documents, and shall permit them to consult with the employees of and counsel to the
Indemnified Party. The Indemnified Party shall use its reasonable best efforts to defend all such claims that the Indemnifying Party does not elect to defend. The failure of the Indemnified Party to give timely notice of a claim shall not relieve
the Indemnifying Party of its indemnification obligations hereunder except to the extent such failure has actually prejudiced the Indemnifying Party. 

  
 61 









 (g) If an Indemnified Party desires to assert any claim for indemnification provided for
under this Article XII other than a claim in respect of, arising out of or involving a third-party claim, such Indemnified Party shall notify the Indemnifying Party in writing, and in reasonable detail (taking into account the information
then available to such Indemnified Party), of such claim promptly after becoming aware of the existence of such claim; provided, however, that the failure of the Indemnified Party to give timely notice of a claim shall not relieve the
Indemnifying Party of its indemnification obligations hereunder unless such failure has actually prejudiced the Indemnifying Party. 
 Section 12.05. Characterization of Indemnification Payments. All amounts paid by Seller or Purchaser in respect of indemnification under this Article XII shall, to the extent permitted by
Law, be treated for all purposes as adjustments to the Initial Purchase Price. 
 Section 12.06. Limitations on
Indemnification. 
 (a) Subject to Section 12.09 and except as otherwise provided herein, Seller shall have no
Liability to the Purchaser Indemnified Parties for any Losses pursuant to this Agreement until the Losses actually incurred by the Purchaser Indemnified Parties exceed an aggregate amount equal to one percent (1%) of the Final Purchase Price
(the “Threshold Amount”) and then only for Losses up to an aggregate amount equal to seventeen and one-half percent (17.5%) of the Final Purchase Price; provided, however, that no indemnity shall be recoverable by
any the Purchaser Indemnified Party for any Losses actually incurred with respect to any individual item or matter unless the amount thereof exceeds US$100,000, and if such amount is not exceeded, then none of the Losses with respect to such item or
matter will count toward satisfying the Threshold Amount. Notwithstanding the foregoing or anything to the contrary contained herein, the limitations on indemnification set forth in this Section 12.06(a) shall not apply to any Losses
attributable to the Excluded Liabilities or the Special Environmental Liabilities or relating to or arising from any breach of the representations and warranties contained in Sections 5.01 (Organization, Power and Authorization; Binding
Effect), 5.05 (Title to Purchased Assets; Sufficiency), 5.08(b) (Compliance with Law), 5.13 (Environmental Matters) or 5.17 (Tax Matters). 
 (b) An Indemnified Party’s right to indemnification pursuant to this Article XII on account of any Losses will be reduced by all insurance or other third party indemnification proceeds
actually received by such Indemnified Party, and any such proceeds shall be taken into account for all purposes hereunder when calculating the Losses actually incurred by such Indemnified Party. The Indemnified Party shall use commercially
reasonable efforts to claim and recover any Losses suffered by such Indemnified Party under any such insurance policies or other third party indemnities. The Indemnified Party shall remit to the Indemnifying Party any such insurance or other third
party proceeds that are paid to the Indemnified Party with respect to Losses for which the Indemnified Party has been previously compensated pursuant to this Article XII. 

(c) An Indemnified Party’s right to indemnification pursuant to this Article XII on account of any Losses will be reduced by
the net amount of the Tax benefits actually realized by such Indemnified Party by reason of such Loss, and the net amount of any such Tax benefits shall be taken into account for all purposes hereunder when calculating the Losses actually incurred
by such Indemnified Party. The Indemnified Party shall use commercially reasonable efforts to claim and realize all such Tax benefits. 

  
 62 









 (d) No Indemnified Party will be entitled to indemnification pursuant to this Article
XII for Losses to the extent that such Indemnified Party has been compensated therefor pursuant to Section 3.02. 
 (e) The Purchaser Indemnified Parties’ right to indemnification pursuant to Section 12.03 on account of any Losses will be reduced by the amount of any reserve reflected on the Financial
Statements established for the specific items or matters giving rise to such Loss. 
 (f) No Indemnified Party shall be entitled
to recover from an Indemnifying Party more than once in respect of the same Losses. 
 (g) Notwithstanding any other provision
of this Agreement, including without limitation this Section 12.06, Seller shall have no obligation to indemnify any Purchaser Indemnified Party (i) for claims arising after the fourth anniversary of the Closing Date for any breach
of any of the representations or warranties contained in Section 5.13 (Environmental Matters), (ii) in respect of the Special Environmental Liabilities following the fourth anniversary of the Closing Date, or (iii) in excess of
$20,000,000 in the aggregate for any breach of any of the representations or warranties contained in Section 5.13 (Environmental Matters) or in respect of the Special Environmental Liabilities. 

(h) Notwithstanding any other provision of this Agreement, Seller’s obligation to indemnify the Purchaser Indemnified Parties for
any breach of any of the representations contained in Section 5.13 (Environmental Matters) or in respect of the Special Environmental Liabilities shall be subject to the following limitations: (i) Seller shall not be responsible for
any increase in the cost of cleanup of any Release of Hazardous Materials or correcting a non-compliance with Environmental Law to the extent that such increase resulted from any voluntary intrusive soil or groundwater sampling conducted in, on, at
or under the Purchased Assets after the Closing Date by or on behalf of Purchaser, the Company or any of their respective employees or representatives which was not conducted in order to assess or otherwise respond to a claim or potential claim
raised by a third party or to assess or prevent what Purchaser reasonably believes to be a material imminent threat to human health or the Environment; and (ii) Seller shall not be responsible for any costs to the extent such costs are incurred
due to any material change in the use of any Seller Property after the Closing Date. 
 Section 12.07. Assignment of
Claims. If the Indemnified Party receives any payment from an Indemnifying Party in respect of any Losses indemnified pursuant to Section 12.02 or Section 12.03 and the Indemnified Party could have recovered all or a part
of such Losses from a third party (a “Potential Contributor”) based on the underlying Claim asserted against the Indemnifying Party, the Indemnified Party, at the request of the Indemnifying Party, shall assign such of its rights to
proceed against the Potential Contributor as are necessary to permit the Indemnifying Party to recover from the Potential Contributor the amount of such payment. 
 Section 12.08. Mitigation. Any Indemnified Party shall take all reasonable steps to mitigate its Losses upon and after becoming aware of any event or condition that could reasonably be expected to
give rise to any Losses that may be indemnifiable hereunder. 

  
 63 









 Section 12.09. Indemnification as Sole Remedy. From and after the Closing, except to
the extent permitted under Section 14.04, the indemnity provided herein as it relates to this Agreement, the transactions contemplated by this Agreement and the Business shall be the sole and exclusive remedy of the Seller Indemnified
Parties and the Purchaser Indemnified Parties with respect to any and all claims for Losses relating to or arising out of this Agreement or the transactions contemplated by this Agreement, whether based on contract, tort, statute, regulation or
other Law, to the exclusion of all remedies provided by any Law in any jurisdiction, and Seller on behalf of the Seller Indemnified Parties and Purchaser on behalf of the Purchaser Indemnified Parties hereby waive any and all rights, both legal or
equitable, to pursue any other remedies in respect of such claims. 
 ARTICLE XIII 

TERMINATION 
 Section 13.01. Termination. This Agreement may be terminated at any time prior to the Closing: 
 (a) by the mutual written agreement of Purchaser and Seller; 
 (b) by either
Purchaser or Seller, by giving written notice of such termination to the other party, if any condition to such party’s obligations hereunder has not been satisfied or waived and the Closing shall not have occurred on or prior to
January 31, 2012 (the “Termination Date”); provided that the Termination Date shall be automatically extended until March 31, 2012 if the conditions set forth in Section 11.01(a) have not been satisfied
or waived by the parties and, as of such date, all other conditions to Closing have been or are capable of being timely satisfied; provided, further, that this Agreement may not be terminated pursuant to this
Section 13.01(b) by a party that is in material breach of its obligations hereunder; 
 (c) by Purchaser by giving
written notice to Seller if there has been a breach of any representation, warranty, covenant or agreement on the part of Seller contained in this Agreement such that the condition set forth in Section 11.02(a) or the condition set forth
in Section 11.02(b) would not be satisfied, and which is either not capable of being cured prior to the Closing or, if such breach is capable of being cured, is not so cured within a reasonable amount of time (and in any event prior to
the Termination Date). 
 (d) by Seller by giving written notice to Purchaser if there has been a breach of any representation,
warranty, covenant or agreement on the part of Purchaser contained in this Agreement such that the condition set forth in Section 11.03(a) or the condition set forth in Section 11.03(b) would not be satisfied, and which is
either not capable of being cured prior to the Closing or, if such breach is capable of being cured, is not so cured within a reasonable amount of time (and in any event prior to the Termination Date). 

Section 13.02. Effect of Termination. In the event of the termination of this Agreement in accordance with
Section 13.01, this Agreement shall thereafter become void and have no effect and neither party hereto (nor any equity holder, director, officer, employee, agent, 

  
 64 









 
consultant or representative of any such party) shall have any Liability to the other party hereto, except in each case for the obligations of the parties hereto contained in
Section 7.07 (Seller Confidentiality), Section 8.01 (Confidentiality), Section 9.03 (Public Announcements), this Section 13.02 and, as applicable, Article XIV (Miscellaneous), each of which
shall survive any termination of this Agreement pursuant to Section 13.01, and except that nothing herein will relieve any party from Liability for any breach of its covenants or agreements contained in this Agreement occurring prior to
such termination.

 Section 14.02. Expenses. Except as otherwise provided herein, all costs and expenses incurred in
connection with this Agreement shall be paid by the party incurring such cost or expense; provided, however, that Purchaser shall pay the full amount of any fees associated with filings made under the HSR Act and any Competition Law.

 Section 14.03. Projections. In connection with Purchaser’s investigation of the Purchased Assets, the Japan
Assets the Assumed Liabilities, the Japan Liabilities and the Business, Purchaser may have received, or may receive, from Seller, the Selling Affiliate and/or their respective representatives certain projections and other forecasts for the Business,
and certain business plan and budget information. Purchaser acknowledges that (a) there are uncertainties inherent in attempting to make such projections, forecasts, plans and budgets, (b) Purchaser is familiar with such uncertainties,
(c) Purchaser is taking full responsibility for making its own evaluation of the adequacy and accuracy of all estimates, projections, forecasts, plans and budgets so furnished to it, and (d) Purchaser will not assert any claim against
Seller, the Selling Affiliate or any of their respective representatives, or hold Seller or any such other Persons liable, with respect thereto. Accordingly, Purchaser acknowledges that Seller makes no representation or warranty with respect to such
estimates, projections, forecasts, plans or budgets and that Seller makes only those representations and warranties explicitly set forth in Article V. 
 Section 14.04. Specific Performance. Each party hereto acknowledges and agrees that the other party hereto could be irreparably damaged in the event any of the covenants contained in this Agreement
are not performed in accordance with their specific terms or are otherwise breached. Accordingly, each party agrees that the other party will be entitled to seek an injunction or injunctions to enforce specifically such covenants in any action
instituted in the courts of the State of Delaware. 
 Section 14.05. Fulfillment of Obligations. Any obligation of any
party to any other party under this Agreement, which obligation is performed, satisfied or fulfilled by an Affiliate of such party, shall be deemed to have been performed, satisfied or fulfilled by such party. 

Section 14.06. Entire Agreement. This Agreement (including all Exhibits and Schedules hereto) constitutes the entire agreement
between the parties with respect to the subject matter of this Agreement and supersedes all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter of this Agreement, except for the
Confidentiality Agreement which will remain in full force and effect for the term provided therein. 

  
 66 









 Section 14.07. Amendments and Waivers. Any provision of this Agreement may be amended
or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each party to this Agreement, or in the case of a waiver, by the party against whom the waiver is to be effective. No failure or delay
by any party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or
privilege. 
 Section 14.08. Successors and Assigns; Third Party Beneficiaries. The provisions of this Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided that, except as set forth below, neither party may assign, delegate or otherwise transfer any of its rights or obligations under
this Agreement without the prior written consent of the other party hereto. Notwithstanding the preceding sentence, Purchaser may assign, in its sole discretion, any of or all its rights, interests and obligations under this Agreement to one or more
direct or indirect wholly-owned subsidiaries of Purchaser (including designating any such entity or entities to act as Purchaser(s) hereunder), but no such assignment shall relieve Purchaser of any of its obligations under this Agreement if its
transferee does not perform such obligations. Any assignment in contravention of this provision shall be null and void. This Agreement shall not confer any rights or benefits upon any Person other than the parties hereto and their respective
successors and permitted assigns, except to the extent otherwise expressly provided herein. 
 Section 14.09.
Severability. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision of this
Agreement, or the application thereof to any Person or any circumstance, is invalid or unenforceable, (a) a suitable and equitable provision shall be substituted therefor in order to carry out, so far as may be valid and enforceable, the intent
and purpose of such invalid or unenforceable provision and (b) the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected by such invalidity or unenforceability, nor shall such
invalidity or unenforceability affect the validity or enforceability of such provision, or the application thereof, in any other jurisdiction. 
 Section 14.10. No Recourse. No past, present or future director, officer, employee, incorporator, member, partner, individual stockholder, agent, attorney or representative of Guarantor, Purchaser
or Seller or any of their respective Affiliates (other than, in the case of the Selling Affiliate, Seller) shall have any liability for any Liabilities of Guarantor, Purchaser or Seller or any of their respective Affiliates under this Agreement or
for any claim based on, in respect of or arising out of the transactions contemplated hereby. 
 Section 14.11.
Interpretation. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” The words “hereof,”
“herein” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement, and “Article,”
“Section,” “clause,” “Exhibit” and “Schedule” references are to the Articles, Sections, clauses, Exhibits and Schedules of this Agreement unless otherwise specified. The captions, heading references and table
of contents 

  
 67 









 
herein are included for convenience of reference only and shall be ignored in the construction or interpretation hereof. The phrases “the date hereof,” “the date of this
Agreement” and phrases of similar import, unless the context otherwise requires, shall be deemed to refer to the date set forth in the Preamble to this Agreement. The word “extent” in the phrase “to the extent” shall mean
the degree to which a subject or other thing extends, and such phrase shall not mean simply “if.” The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If any ambiguity or question of intent or
interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this
Agreement. 
 Section 14.12. Disclosure Schedule. The Disclosure Schedule constitutes an integral part of this Agreement
and is hereby incorporated herein. There may be included in the Disclosure Schedule and elsewhere in this Agreement items and information that are not “material,” and such inclusion shall not be deemed to be an acknowledgment or agreement
that any such item or information (or any non-disclosed item or information of comparable or greater significance) is “material,” or to affect the interpretation of such term for purposes of this Agreement. Disclosures included in any
section of the Disclosure Schedule shall be considered to be made for purposes of all other sections of the Disclosure Schedule to the extent that the relevance of any such disclosure to any other section of the Disclosure Schedule is readily
apparent on its face. Matters reflected in the Disclosure Schedule are not necessarily limited to matters required by this Agreement to be disclosed in the Disclosure Schedule. No disclosure in the Disclosure Schedule relating to a possible breach
or violation of any Contract or Law shall be construed as an admission or indication that such breach or violation exists or has occurred. Any capitalized term used in the Disclosure Schedule and not otherwise defined therein shall have the meaning
given to such term in this Agreement. Any headings set forth in the Disclosure Schedule are for convenience of reference only and shall not affect the meaning or interpretation of any of the disclosures set forth in the Disclosure Schedule.

 Section 14.13. Governing Law; Jurisdiction. This Agreement and the transactions contemplated hereby, and all disputes
between the parties hereto under or relating to this Agreement or the transactions contemplated hereby, whether in contract, tort or otherwise, shall be governed by, and construed and enforced in accordance with, the internal Laws of the State of
Delaware, without regard to any conflicts of law rules thereof that would result in the application of the Law of any other State. The Delaware Court of Chancery sitting in Wilmington, Delaware (and if 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) will have exclusive jurisdiction over any and all disputes among the parties hereto, whether at law or in equity, based
upon, arising out of or relating to this Agreement and the transactions contemplated hereby or the facts and circumstances leading to its execution and delivery, whether in contract, tort or otherwise. Each of the parties hereto irrevocably consents
to and agrees to submit to the exclusive jurisdiction of such courts, agrees that process may be served upon them in any manner authorized by the Laws of the State of Delaware, and hereby waives, and agrees not to assert in any such dispute, to the
fullest extent permitted by applicable Law, any claim that (a) such party is not personally subject to the jurisdiction of such courts, (b) such party and such party’s property is immune from any legal process issued by such courts or
(c) any litigation commenced in such courts is brought in an inconvenient forum. EACH OF THE PARTIES 

  
 68 









 
HERETO IRREVOCABLY CONSENTS TO THE SERVICE OF PROCESS OUTSIDE THE TERRITORIAL JURISDICTION OF THE COURTS REFERRED TO IN THIS SECTION 14.14 IN ANY ACTION OR PROCEEDING UNDER OR
RELATING TO THIS AGREEMENT OR THE FACTS AND CIRCUMSTANCES LEADING TO ITS EXECUTION AND DELIVERY BY MAILING COPIES THEREOF BY REGISTERED UNITED STATES MAIL, POSTAGE PREPAID, RETURN RECEIPT REQUESTED, TO ITS ADDRESS AS SPECIFIED IN OR PURSUANT TO
SECTION 14.01. HOWEVER, THE FOREGOING SHALL NOT LIMIT THE RIGHT OF A PARTY TO EFFECT SERVICE OF PROCESS ON ANY OTHER PARTY BY ANY OTHER LEGALLY AVAILABLE METHOD. Nothing in this Section 14.14 shall limit the jurisdictions in which
a judgment may be enforced. 
 Section 14.14. WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES
ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 Section 14.15. Counterparts; Electronic Transmission. 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. Counterparts delivered by electronic transmission shall be
deemed to be originally signed counterparts. 
 ARTICLE XV 

GUARANTEE BY GUARANTOR 
 Section 15.01. Guarantee and Indemnity. Guarantor unconditionally and irrevocably: 
 (a) guarantees to Seller and the Selling Affiliate the performance of all obligations of Purchaser under this Agreement; 
 (b) agrees that if and each time that Purchaser fails to perform its obligations under this Agreement, Guarantor must on demand (without requiring Seller and the Selling Affiliate first to take steps
against Purchaser or any other person) perform such obligations as if it were the principal obligor in respect thereof; and 

(c) agrees as principal debtor and primary obligor to indemnify Seller and the Selling Affiliate against, and to pay to Seller or the
Selling Affiliate, as appropriate, on demand an amount equal to all Losses directly or indirectly incurred or suffered by Seller or the Selling Affiliate arising out of or in connection with any non-performance of any kind by Purchaser under this
Agreement. 
 Section 15.02. Obligations Not Affected by Certain Matters. The obligations of Guarantor under this
Agreement are not affected by any matter or thing which but for this provision might operate to affect or prejudice those obligations, including: 
 (a) any time or indulgence granted to, or composition with, Purchaser or any other Person; 

  
 69 









 (b) the taking, variation, renewal or release of, or neglect to perfect or enforce this
Agreement, or any right, guarantee, remedy or security from or against Purchaser or any other Person; 
 (c) any variation or
change to the terms of, or any waiver, consent or notice given under, this Agreement; or 
 (d) any unenforceability or
invalidity of any obligation of Purchaser, so that this Agreement must be construed as if there were no such unenforceability or invalidity. 
 Section 15.03. Purchaser’s Actions to Bind Guarantor. Any agreement, waiver, consent or release given by Purchaser shall bind Guarantor.
