Section 2.3 Purchase Price Adjustment.

(a) Preliminary Purchase Price Adjustment. No later than three (3) Business Days prior to the Closing Date, TDY shall prepare and deliver to Buyer a statement setting forth its good faith estimate of (i) the Net Working Capital of the Tungsten Materials Business (the "Estimated Net Working Capital"), as of the Effective Time and as estimated in accordance with the Closing Net Working Capital Principles, and (ii) subject to Section 5.8(n), the amount of any Cash Equivalents to be held by any of the Transferred Subsidiaries as of the Effective Time (the "Estimated Closing Cash Amount"). For purposes of the calculation of Net Working Capital of the Tungsten Materials Business, all of the Transferred Assets and the Shares shall be deemed to have been conveyed as of the Effective Time (regardless of any delayed transfer pursuant to Section 5.17) and shall be included, to the extent applicable, in the calculation of the

Final Net Working Capital. For illustrative purposes only, Annex C sets forth an example of the methodology by which the Preliminary Purchase Price is to be determined.

(b) Post-Closing Purchase Price Determination.

(i) As soon as practicable, but in no event later than sixty (60) days after the Closing Date, Buyer shall prepare and deliver to TDY the following (collectively, the "Preliminary Adjustment Statement"):

(A) a statement setting forth (x) a reasonably detailed calculation by Buyer of the Net Working Capital of the Tungsten Materials Business, prepared by Buyer in accordance with the Closing Net Working Capital Principles and on a basis consistent with the Preliminary Closing Net Working Capital Statement, and (y) the amount of any Cash Equivalents held by any of the Transferred Subsidiaries as of the Effective Time (together, the "Closing Adjustment Amounts"); and

(B) a certificate of an executive officer of Buyer certifying that the Preliminary Closing Net Working Capital Statement has been prepared in accordance with the Closing Net Working Capital Principles.

(ii) If TDY disagrees with Buyer's calculation of the Closing Adjustment Amounts, TDY shall promptly, but in no event later than forty-five (45) days after receiving the Preliminary Adjustment Statement (the "Review Period"), deliver to Buyer written notice describing its dispute by specifying those items or amounts as to which TDY disagrees, together with TDY's determination of such disputed items and amounts (a "Dispute Notice"). If TDY either gives notice that it agrees with Buyer's calculation of the Closing Adjustment Amounts or fails to deliver a Dispute Notice within the Review Period, Buyer and TDY agree that the Preliminary Adjustment Statement shall be deemed to set forth the Closing Adjustment Amounts with respect to those items that have been agreed upon or for which TDY shall have failed to deliver a Dispute Notice (and shall constitute the Final Net Working Capital and Final Closing Cash Amount). If TDY delivers a Dispute Notice to Buyer within the Review Period, TDY and Buyer will use good faith efforts to resolve the dispute during the 30-day period commencing on the date TDY delivers the Dispute Notice to Buyer (and all such discussions related thereto shall be governed by Rule 408 of the United States Federal Rules of Evidence, and any applicable similar state rule and evidence of such discussions shall not be admissible in any future proceedings between the parties). If Buyer and TDY are not able to resolve all disputed items within such 30-day period, then either party shall have the right to submit the items in dispute following the expiration of such 30-day period to KPMG LLP, or if KPMG LLP is unwilling to serve, to another mutually acceptable internationally recognized independent accounting firm (the "Accounting Firm"). The Accounting Firm shall be given reasonable access to all relevant records of the Tungsten Materials Business to calculate the Closing Adjustment Amounts. If any remaining issues

in dispute are submitted to the Accounting Firm for resolution, each of Buyer and TDY will be afforded an opportunity to present to the Accounting Firm any material relating to the determination of the matters in dispute and to discuss such matters with the Accounting Firm (with any such materials to be submitted to the Accounting Firm within ten days following the expiration of the 30-day period referenced above). The Accounting Firm shall calculate, based solely on the written submissions of Buyer, on the one hand, and TDY, on the other hand, and not by independent investigation, the Closing Adjustment Amounts and shall be instructed that its calculation (A) must be made in accordance with the standards and definitions in this Agreement (including the Closing Net Working Capital Principles) and Exhibit B, and (B) with respect to each item in dispute, must be within the range of values established for such amount as determined by reference to the value assigned to such amount by TDY in the Dispute Notice and by Buyer in the Preliminary Adjustment Statement. The Accounting Firm shall submit such calculation to TDY and Buyer as soon as practicable, but in any event within thirty (30) days after the remaining issues in dispute are submitted to the Accounting Firm. The determination by the Accounting Firm of the Closing Adjustment Amounts, as set forth in a written notice delivered to Buyer and TDY by the Accounting Firm in accordance with this Agreement, will, in the absence of fraud or manifest error, be binding and conclusive on Buyer and TDY. In making its determination, the Accounting Firm shall act as an expert and not as an arbitrator. The scope of the disputes to be resolved by the Accounting Firm shall be limited to the determination of whether the Closing Adjustment Amounts were properly calculated in accordance with the Closing Net Working Capital Principles, and the Accounting Firm is not to make any other determination or interpretations with respect to the Agreement. The Closing Adjustment Amounts as determined after all disputes have been resolved in accordance with this Section 2.3(b)(ii) are referred to herein as the "Final Net Working Capital" with respect to the final determination of the Net Working Capital and as the "Final Closing Cash Amount" with respect to the final determination of the amount of any Cash Equivalents held by the Transferred Subsidiaries as of the Effective Time.

(iii) Buyer and TDY shall each pay one-half of the fees and expenses of the Accounting Firm.

(iv) In connection with TDY's review of the Preliminary Adjustment Statement, Buyer shall (i) provide reasonable access, during normal business hours and upon reasonable notice, to its employees and all work papers, schedules, memoranda and other documents prepared or reviewed by Buyer or any of its employees and accountants or other representatives during the course of its review which are relevant to the Preliminary Adjustment Statement (which access shall be provided promptly after request by TDY and/or its representatives) and (ii) use its reasonable best efforts to cause Buyer's independent accountant to

communicate and cooperate with TDY and its representatives with respect to such review.

(v) The process set forth in this Section 2.3(b) shall be the exclusive remedy of TDY and Buyer for any disputes related to the Closing Adjustment Amount, whether or not the underlying facts and circumstances constitute a breach of any representations or warranties contained in this Agreement; provided, however, that this provision shall not prevent either party from seeking indemnification in accordance with Section 8.4 of this Agreement for Losses arising from or in connection with a breach of any representation or warranty not related to the subject matter of this Section 2.3 and the calculations made pursuant hereto.

(i) The Final Purchase Price shall be equal to the Preliminary Purchase Price, (w) plus, if the Final Net Working Capital as determined pursuant to Section 2.3(b)(ii) exceeds the Estimated Net Working Capital, the amount of such excess, (x) minus, if the Estimated Net Working Capital exceeds the Final Net Working Capital as determined pursuant to Section 2.3(b)(ii), the amount of such excess, (y) plus, if the Final Closing Cash Amount as determined pursuant to Section 2.3(b)(ii) exceeds the Estimated Closing Cash Amount, the amount of such excess, (z) minus, if the Estimated Closing Cash Amount exceeds the Final Closing Cash Amount as determined pursuant to Section 2.3(b)(ii), the amount of such excess (the difference between the Preliminary Purchase Price and the Final Purchase Price, the "Final Closing Adjustment").

(ii) Buyer or TDY, as the case may be, shall, within five (5) Business Days after the determination of the Final Net Working Capital and Final Closing Cash Amount pursuant to Section 2.3(b)(ii), make payment to the other by wire transfer of immediately available funds to one or more accounts designated by the other of the amount of the Final Closing Adjustment as determined pursuant to Section 2.3(c)(i), together with interest thereon at a rate equal to the prime rate as published in The Wall Street Journal in effect on the Closing Date, for the period from the Closing Date through and including the date of payment.

Section 2.4 Allocation of Purchase Price. Within sixty (60) calendar days of the Closing, Buyer shall provide to TDY a schedule which will provide for the allocation of the Preliminary Purchase Price and the Assumed Liabilities among the Shares, the Transferred Assets and the Tungsten Materials IP assigned pursuant to the IP Assignment Agreements, in a manner consistent with Section 1060 of the Code and the Treasury Regulations promulgated thereunder (the "Purchase Price Allocation"). The Purchase Price Allocation shall attribute such allocated amounts to TDY and the Share Sellers based on their ownership of the Shares, the Transferred Assets and the Tungsten Materials IP assigned pursuant to the IP Assignment Agreement on the date of this Agreement, which ownership allocation is set forth on Section 2.4 of the Seller’s Disclosure Schedule. The Purchase Price Allocation shall be subject to the review

and consent of TDY. If TDY does not object to the Purchase Price Allocation by written notice to Buyer within thirty (30) Business Days after receipt, then the Purchase Price Allocation shall be deemed to have been accepted and agreed upon, and final and conclusive, for all purposes of this Agreement. If TDY objects to the Purchase Price Allocation, it shall notify Buyer in writing of its objection within thirty (30) Business Days after receipt by Buyer of the Purchase Price Allocation and shall set forth in such written notice the disputed item or items and the basis for its objection, and TDY and Buyer shall act in good faith to resolve any such dispute for a period of fifteen (15) Business Days thereafter. If, within fifteen (15) Business Days of TDY’s delivery of a valid written notice of objection to the Purchase Price Allocation, Buyer and TDY have not reached an agreement regarding the disputed item or items specified in such written notice, the dispute shall be presented to the Accounting Firm, whose determination shall be binding upon the parties. The fees and expenses of the Accounting Firm in connection with the resolution of any dispute under this Section 2.4 shall be paid fifty percent (50%) by TDY and fifty percent (50%) by Buyer. If necessary, Buyer shall make appropriate adjustments to the Purchase Price Allocation to reflect the difference, if any, between the Preliminary Purchase Price and the Final Purchase Price as determined pursuant to Section 2.3. The parties shall (i) timely file all Tax Returns (including United States Internal Revenue Service Form 8594 and any supplemental filings to reflect any revisions to the Purchase Price Allocation) required to be filed in connection with the Purchase Price Allocation, and (ii) prepare and file all Tax Returns and determine all Taxes in a manner consistent with the Purchase Price Allocation. Each of the parties shall notify the other if it receives notice that any Tax Authority proposes any allocation different from that set forth on the Purchase Price Allocation.

For purposes of this Agreement, “net realizable value” is defined as the lower of cost or market, where market represents the historical range of selling prices for Tungsten Materials Inventory. Since December 31, 2012, there has not been a material change in the method of valuing the Tungsten Materials Inventory. Section 3.21 of the Seller’s Disclosure Schedule sets forth all Contracts

pursuant to which material amounts of Tungsten Materials Inventory has been consigned to others.

Section 3.22 Accounts Receivable.

Notwithstanding the foregoing, in the event that any Delayed Antitrust Approval has not been obtained within twenty-four (24) months of the Closing Date, TDY shall have the right at any time thereafter, in its sole discretion, to sell any of the affected Tungsten Materials Assets, the Shares or Assumed Liabilities to a third party at a price determined in good faith by TDY to be a commercially reasonable price, and upon consummation of any such sale, (x) TDY shall pay the proceeds of such sale to Buyer (provided that TDY may reduce such payment by an amount equal to its fees and expenses (or an estimate thereof) and any incremental Taxes payable as a result of such sale) and (y) the obligations of the parties pursuant to this Section 5.3(c) (other than pursuant to the preceding clause (x)) with respect to such Tungsten Materials Assets or Assumed Liabilities shall cease.

(d) During the period from the date of this Agreement until the Closing Date (or such later date on which all transfers of the Tungsten Materials Business and Tungsten Materials Assets contemplated by Section 5.18 have been completed), except as required by this Agreement, Buyer and its Affiliates shall not, without the prior written consent of TDY, engage in any action or enter into any transaction or permit any action to be taken or transaction to be entered into, that would reasonably be expected to have a Buyer Material Adverse Effect. Without limiting the generality of the foregoing, none of Buyer or its Affiliates shall, and shall not cause any Person to, acquire (whether via merger, consolidation, stock or asset purchase or otherwise), or agree to so acquire, any assets of or any equity in any other Person or any business or division thereof, unless that acquisition or agreement would not reasonably be expected to materially (x) increase the risk of not obtaining any authorizations, consents, orders, declarations or approvals of any Governmental Authority necessary to consummate the transactions contemplated by this Agreement or the expiration or termination of any waiting period under any Regulatory Law; (y) increase the risk of any Governmental Authority entering an order prohibiting the consummation of the transactions contemplated by this Agreement, or materially increase the risk of not being able to remove any such order on appeal or otherwise; or (z) delay or prevent the consummation of the transactions contemplated by this Agreement.

(e) Subject to the terms and conditions set forth in this Agreement, Buyer shall, and shall cause its Affiliates to, use reasonable best efforts to obtain all Permits, if any, relating to any Export Control and Import Laws necessary for Buyer and its Affiliates, as applicable, to operate the Tungsten Materials Business in their respective names, as the case may be, and TDY shall cooperate with Buyer and its Affiliates in their efforts to obtain such Permits.

Section 5.4 Further Assurances. Except as otherwise provided in this Agreement and subject to Section 5.3 and Section 5.18, each of the parties hereto agrees to use its reasonable best efforts before and after the Closing Date to take or cause to be taken all action, to do or cause to be done, and to assist and cooperate with the other party hereto in doing, all things necessary, proper or advisable under applicable Laws to consummate and make effective, in the most expeditious manner practicable, the transactions contemplated by this Agreement, including, but not limited to, (i) the satisfaction of the conditions precedent to the obligations of any of the parties hereto; (ii) the obtaining of all necessary consents, approvals or waivers from Governmental Authorities required to be obtained by TDY or Buyer, or their respective Affiliates, in connection with the transactions contemplated by this Agreement (other than with respect to Regulatory Laws which are the subject of Section 5.3); (iii) to the extent consistent with the obligations of the parties set forth in Section 5.3, the defending of any Actions, whether judicial or administrative, challenging this Agreement or the consummation of the transactions contemplated hereby; and (iv) the execution and delivery of such instruments, and the taking of such other actions, as the other party hereto may reasonably require in order to carry out the intent of this Agreement. TDY shall use its commercially reasonable efforts, and Buyer shall reasonably cooperate with TDY, prior to the Closing Date, to obtain all consents and approvals from applicable third parties to all Contracts of the Tungsten Materials Business,

including the Contracts set forth in Section 5.4 of the Seller's Disclosure Schedule; provided that neither party shall be required to make any payments, incur any Liability or offer or grant any accommodation (financial or otherwise) to any such third party in connection with obtaining any such consents and approvals; and provided, further, that TDY shall use its reasonable best efforts, and Buyer shall reasonably cooperate with TDY, prior to the Closing Date, to obtain the consent to the assignment to Buyer of the Contracts identified under the heading “Special Consent” as set forth in Section 5.4 of the Seller's Disclosure Schedule from the applicable third party to such Contracts.

Section 5.5 Intercompany Accounts and Arrangements.

(a) All material intercompany arrangements and agreements, whether written or oral, providing for the leasing or licensing of goods, services, tangible or intangible properties or joint activities between ATI or any of the Retained Subsidiaries, on the one hand, and TDY (in respect of the Tungsten Materials Business) or a Transferred Subsidiary, on the other hand, are set forth in Section 5.5 of the Seller’s Disclosure Schedule (the “Intercompany Agreements”). Except for the Related Agreements, all intercompany arrangements and agreements, whether written or oral, providing for the leasing or licensing of goods, services, tangible or intangible properties or joint activities between ATI or any of the Retained Subsidiaries, on the one hand, and TDY (in respect of the Tungsten Materials Business) or a Transferred Subsidiary, on the other hand, including the Intercompany Agreements, shall be terminated at TDY’s expense by TDY (or TDY shall cause such agreements to be terminated) and such agreements shall be of no further force and effect after the Closing. Effective upon the Closing, all outstanding intercompany accounts, whether payables or receivables, between ATI or any of the Retained Subsidiaries, on the one hand, and TDY (in respect of the Tungsten Materials Business) or a Transferred Subsidiary, on the other hand, shall be settled and/or cancelled by TDY (or TDY shall cause such intercompany accounts to be settled or cancelled) and such intercompany accounts shall be and of no further force and effect (it being understood that such settlement or cancellation shall not in any way affect the Related Agreements or any amounts which may be payable pursuant to the Related Agreements).

(b) Provided TDY has satisfied its obligations under Section 5.5(a), effective as of the Closing, Buyer, on behalf of itself and its Affiliates, hereby releases TDY and its Affiliates (and their respective officers, directors and employees, acting in their capacity as such) from any Liability, obligation or responsibility to any of them for any and all past actions or failures to take action prior to the Closing, including any actions which may be deemed to have been negligent or grossly negligent, relating to or arising out of Contracts with ATI or a Subsidiary thereof or the operation or conduct of any businesses, Assets (including activities performed thereat) or operations managed or operated by, or operationally related to, directly or indirectly, the Tungsten Materials Business or the Excluded Businesses, except for any obligation pursuant to the provisions of this Agreement or the Related Agreements.

Section 5.6 Provision of Corporate Records. As soon as practicable on or after the Closing Date, as permitted by Law, TDY shall use its commercially reasonable efforts to

deliver or cause to be delivered to Buyer all Transferred Tungsten Materials Books and Records then in the possession of ATI or any Retained Subsidiary, and Buyer shall use its commercially reasonable efforts to deliver or cause to be delivered to TDY all ATI Books and Records, if any, then in the possession of Buyer or its Affiliates. The foregoing shall be limited by the following specific provisions:

(a) To the extent any document (other than that stored on electronic media) can be subdivided without unreasonable effort into two portions, one of which constitutes a Transferred Tungsten Materials Book and Record and the other of which constitutes a ATI Book and Record, such document (other than that stored on electronic media) shall be so sub-divided, and the original of the portion such document (other than that stored on electronic media) which constitutes a Transferred Tungsten Materials Book and Record shall be provided to Buyer (with a copy thereof provided to TDY) and the original of the portion such document (other than that stored on electronic media) which constitutes an ATI Book and Record shall be provided to TDY (with a copy thereof provided to Buyer).

(b) Neither party shall be required to conduct any company-wide search or investigation of files.

(c) For purposes of this Section 5.6, "commercially reasonable efforts" shall require deliveries of books and records that on their face are Transferred Tungsten Materials Books and Records or ATI Books and Records, as applicable, and any such specific and discrete books and records related to the Tungsten Materials Business or the Excluded Businesses, as applicable, reasonably requested in writing by either party and then in the possession of the other party.

(d) Each party may retain copies of the books and records of the other already in its possession, and may use such books and records as reasonably required for its normal business purposes, subject to this Agreement and the Related Agreements, and subject to holding in confidence information contained in such books and records in accordance with the requirements and limitations of this Agreement including Sections 5.13 and 5.14. If either party has a reasonable concern regarding the other party's use of such books and records, such party may, upon reasonable prior written notice and at such party's expense, audit the other party's use of such books and records at times and in a manner reasonably acceptable to all parties.

(e) Each party may refuse to furnish any Information if it believes in good faith that doing so presents, based on an opinion of counsel (which can be inside counsel), a significant risk of loss of the ability to successfully assert a claim of Privilege; provided that the parties hereto shall cooperate in seeking to find a way to allow disclosure of such information without resulting in a loss of the ability to successfully assert a claim of Privilege.

(f) Neither party shall be required to deliver to the other books and records or portions thereof (i) if such delivery would violate any applicable Law or (ii) which are

subject to confidentiality agreements which would by their terms prohibit such delivery; provided, however, if requested by the other party, such party shall use its commercially reasonable efforts to seek a waiver of such confidentiality restriction.

(g) TDY may redact any Information covered by this Section 5.6 as and to the extent such Information relates to the Excluded Businesses, the Excluded Assets or the Retained Liabilities.

(h) Buyer may redact any Information covered by this Section 5.6 as and to the extent such Information relates to Buyer's business, assets or liabilities other than the Tungsten Materials Assets, the Transferred Subsidiaries and the Assumed Liabilities.

Section 5.7 Retained Names.

(a) Following the Closing, Buyer shall and shall cause its Subsidiaries to, as soon as practicable, but in no event later than (i) thirty (30) days following the Closing Date, change their names, including making any necessary legal filings with the appropriate Governmental Authority to effectuate such change, and cause their certificates of incorporation (or equivalent organizational documents), as applicable, to be amended, to remove any reference to "ATI", or any other Retained Name, (ii) 270 days following the Closing Date, cease to use or to permit any third party to use any Retained Names, and (iii) 270 days following the Closing Date remove, strike over, or otherwise obliterate all Retained Names from all assets and other materials owned or possessed by Buyer or its Affiliates, including any vehicles, business cards, schedules, stationery, packaging materials, displays, signs, promotional materials, manuals, forms, websites, email, computer software and other materials and systems, other than materials owned or possessed by Buyer or its Affiliates that are part of such party’s internal records and are not available to non-Affiliates of Buyer. Notwithstanding the foregoing, Buyer shall not, and shall cause its Affiliates and employees not to, hold themselves out as carrying on the Tungsten Materials Business as TDY or ATI.

(b) Any use of the Retained Names by Buyer and its Affiliates (in respect of the Tungsten Materials Business) permitted by this Section 5.7 shall be subject to the following conditions:

(i) Use of the Retained Names shall be in the same form and manner, to no greater extent (without an increase in the extent or type of uses of the Retained Names), and subject to the same standards of quality, of that in effect for the Retained Names as of the Closing Date;

(ii) The Retained Names shall not be used in a manner that would reasonably be expected to reflect negatively on such name and marks or on ATI, TDY or any of their respective Affiliates;

(iii) Buyer and its Affiliates shall not apply to register or register any of the Trademarks forming a part of or associated with the Retained Names;

(iv) Any press release or similar public announcement or communication that references any of the Retained Names shall include a statement that Buyer or its Affiliates, as applicable, and TDY or its Affiliates, as applicable, are not Affiliates or otherwise related to each other;

(v) Buyer and its Affiliates shall, in connection with all written uses of the Retained Names in connection with the Tungsten Materials Business, including on any packaging materials, displays, signs, promotional materials, forms, and websites, include a clear statement that the associated products or services are manufactured by or otherwise emanate from Buyer and not from TDY, ATI or its Affiliates (provided that Buyer may not create any new packaging or other materials); and

(vi) Upon the expiration or termination of their respective rights under this Section 5.7, Buyer and its Affiliates hereby assign to TDY their rights, if any, to any Trademarks forming a part of or associated with the Retained Names that they may retain.

(c) At the request of TDY, Buyer shall and shall cause its Affiliates to provide to TDY reasonable and representative samples of products and materials used or created under or in connection with this Section 5.7, in their possession, custody, or under their control bearing any of the Retained Names and shall permit TDY to inspect their premises and shall otherwise cooperate with TDY to assist TDY in ensuring that the conditions of use of the Retained Names set forth under Section 5.7(b) are complied with.

(d) Buyer and its Affiliates shall have no other right to use any of the Retained Names except as expressly set forth in this Section 5.7.

Without limitation to any other remedies, if Buyer and its Affiliates fail to comply with the foregoing terms and conditions or otherwise fail to comply with any reasonable direction of TDY or any of its Affiliates in relation to the use of the Retained Names, TDY shall (i) be entitled to seek a temporary, preliminary or permanent injunction or other equitable relief in accordance with Section 9.7, and (ii) have the right to terminate the foregoing permitted use, effective immediately. Buyer and its Affiliates shall indemnify and hold harmless TDY and its Affiliates for any Losses arising from or relating to the use by Buyer or any of its Affiliates of the Retained Names pursuant to this Section 5.7.

Section 5.8 Employee Matters. Subject to the terms of the Transition Services Agreement, the parties agree as follows:

(a) Except to the extent otherwise required by applicable Law and subject to Section 5.8(m), not later than three (3) weeks before the Closing Date, Buyer shall, or shall cause one of its Affiliates to, offer employment to each individual primarily employed in the Tungsten Materials Business by TDY or its Affiliates as of the date of such offer (which employees are set forth on Section 5.8(a) of the Seller’s Disclosure Schedule, which Disclosure Schedule shall be updated by TDY and provided to Buyer no

later than two (2) weeks before the Closing Date), subject to each person’s completion and satisfaction of Buyer’s customary pre-employment conditions, effective as of the Closing Date on terms and conditions that are, at a minimum, substantially similar to those in effect with respect to such individual as in effect as of immediately before the Closing Date and providing, for one (1) year following the Closing Date, for cash compensation (e.g., base salary or wage rate, variable compensation and long-term compensation opportunity) not less favorable than that in effect with respect to such individual immediately before the Closing Date (or, for such individuals whose principal work location is outside the United States, as otherwise required by law or local custom) and benefits which are no less favorable than those benefits Buyer customarily provides to its similarly-situated employees (after taking into account Section 5.8(b)), as applicable; provided, however, that except as otherwise set forth in any agreement (other than this Agreement or the Related Agreements) with any such employee or as required by applicable Law, nothing herein shall preclude Buyer from terminating the employment of any such employee at any time on or after the Closing. TDY shall cause its Affiliates to cooperate with Buyer to encourage such individuals to accept such offer of employment and to effect any communications, access to populations, and such other actions as may be necessary or reasonable to facilitate such employment offer. Each Business Employee who accepts such offer of employment and commences employment with Buyer or its Affiliates on his or her first regularly scheduled working day on or following the Closing Date or, if later, upon return from an approved leave of absence, shall be referred to herein as a "Transferred Employee." For the avoidance of doubt, Buyer shall not be required to offer employment to any individual primarily employed in the Tungsten Materials Business who is on long term disability (and not on an approved leave of absence) as of the date hereof.

(b) On and after the Closing Date, Buyer shall, and as applicable shall cause its Affiliates to, give Transferred Employees service credit for purposes of eligibility, vesting and determination of the level of future benefits under any employee benefit plan maintained by Buyer or its Affiliates for the benefit of similarly situated employees (after taking into account seniority or length of service with TDY and its Affiliates; provided, however that no Transferred Employee shall be entitled to participate in any benefit plan of Buyer or its Affiliate that is frozen or closed to new entrants), except to the extent that such recognition would result in a duplication of benefits for service with TDY or any of its Affiliates prior to the Closing Date, but in any event only to the extent such service was recognized under a Benefit Plan immediately prior to the Closing Date.

(c) Except as otherwise specifically provided in this Section 5.8, as of the Closing Date, with respect to any Liability or obligation to, or in respect of, any Transferred Employee not otherwise provided for in this Agreement, whether arising out of actions, events or omissions that occurred (or, in the case of omissions, failed to occur) on or after the Closing Date, Buyer shall assume and be solely responsible for all such Liabilities and obligations whatsoever with respect to Transferred Employees to the extent such Liabilities and obligations (i) arise or arose in connection with the conduct or operation of the Tungsten Materials Business (exclusive of wages (including bonuses and

commissions), incentive compensation, equity compensation, severance, and Benefit Plan contributions payable and/or accrued in respect of the period before the Closing Date, which shall be paid by TDY or its Affiliates (unless any such items are accrued as current liabilities or adjustments specified in the calculation of the Final Net Working Capital)) or (ii) arise or arose under Title VII of the United States Civil Rights Act of 1964, the United States Civil Rights Act of 1991, the United States Age Discrimination in Employment Act of 1967, the United States Equal Pay Act, the Americans with Disabilities Act of 1990, the United States Employee Retirement Income Security Act of 1974, the United States Health Insurance Portability and Accountability Act of 1996 and all other United States federal, state or local statutes regulating the terms and conditions of employment, or under the common law or in equity, including any claims for wrongful discharge or otherwise. Buyer agrees to reimburse TDY, as soon as practicable but in any event within thirty (30) days of receipt from TDY of appropriate verification, for all costs and expenses actually paid by TDY or its Affiliates after the Closing Date to the extent that the Liabilities related to such costs and expenses have been assumed by Buyer pursuant to the foregoing provisions of this subsection (c).

(d) To the extent permitted by Law, Buyer shall, and as applicable shall cause its Affiliates to, (i) cause any preexisting condition restrictions, other restrictions or waiting periods under employee benefit plans of Buyer or its Affiliates to be waived to the extent necessary to provide immediate coverage to each Transferred Employee who was covered as of the Closing Date under Benefit Plans that provide medical or dental benefits and (ii) cause any employee benefit plan of Buyer or its Affiliates which is a welfare benefit plan to apply any amounts paid under a welfare benefit plan of TDY or any of its Affiliates by a Transferred Employee as deductibles and coinsurance during the plan year in which the Closing Date occurs toward deductible, coinsurance and out-of-pocket limits under such plan of Buyer or its Affiliates for the plan year in which the Closing Date occurs (with appropriate adjustments for differences in plan years).

(e) Without limiting the provisions of subsection (a) above, for a period of one (1) year following the Closing Date, Buyer shall, or shall cause its Affiliates to, maintain a severance plan for the Transferred Employees which provides for cash severance in the amount and upon the terms and conditions (i.e., events of eligibility) substantially similar to the cash amounts and terms and conditions as in effect on the date hereof in respect of existing employees of Buyer on the date of this Agreement (exclusive of change in control, equity acceleration, tax gross up, welfare benefit and any similar provisions in any such severance program).

(f) Buyer shall, and shall cause its Affiliates to, honor all accrued but untaken vacation credited to Transferred Employees under the paid time off plans of TDY and its Affiliates that has not been cashed out on or before the Closing Date and provide that, with respect to each Transferred Employee, for a period of not less than one (1) year following the Closing Date, the rate of accrual of hours of vacation or other paid-time-off for employment with Buyer or its Affiliates after the Closing shall not be less than such rate of accrual with TDY or its Affiliates immediately prior to the Closing.

(g) TDY or its Affiliates shall be solely responsible for all Liabilities under the 401(k) Plan of ATI (the "ATI 401(k) Plan"). Buyer or an Affiliate of Buyer shall establish or maintain a defined contribution plan and trust intended to qualify under Section 401(a) and Section 501(a) of the Code that on or after the Closing Date shall accept a contribution, in cash or, to the extent of any notes associated with the outstanding balance of any loans to Transferred Employees, in kind, attributable to any eligible rollover distribution (within the meaning of Section 401(a)(31) of the Code) of the benefit of a Transferred Employee under the ATI 401(k) Plan; provided, that the obligation to accept such a rollover in kind shall expire twelve (12) months after the Closing Date (or at such other time as Buyer and TDY may mutually agree).

(h) Effective as of the Closing Date, TDY (or its Affiliates) shall retain and be solely responsible for the Liabilities and obligations to or in respect of Transferred Employees under any Benefit Plan not sponsored by a Transferred Subsidiary, except as otherwise provided in Section 5.8(k).

(i) TDY (or its Affiliates) shall retain and be solely responsible for all Liabilities and obligations with respect to Transferred Employees under all United States defined benefit pension plans that are maintained by TDY or any of its Affiliates and that are intended to be "qualified" within the meaning of Section 401(a) of the Code, including without limitation the Allegheny Technologies Incorporated Pension Plan, and accordingly there shall be no transfer of assets or liabilities among TDY, Buyer, any of their Affiliates or their respective plans in respect of such defined benefit pension plans.

(j) TDY (or its Affiliates) shall retain and be solely responsible for all Liabilities to Transferred Employees under each post-retirement welfare benefit plan maintained by ATI or its Subsidiaries for Business Employees whose principal work location is in the United States as of the Closing Date. TDY (or its Affiliates) shall provide and be solely responsible for any continuation coverage required under Section 4980B of the Code, Part 6 of Title I of ERISA or applicable state law ("COBRA") in respect of each Business Employee whose "qualifying event" (as defined in COBRA) occurs on or prior to the Closing Date. TDY shall provide any certificates of creditable coverage under the Health Insurance Portability and Accountability Act of 1996 required by reason of transactions contemplated by this Agreement.

(k) The Assumed Collective Bargaining Agreement and the Multiemployer Plan will be addressed as follows:

(i) Buyer shall negotiate in good faith with the International Association of Machinists and Aerospace Workers, AFL-CIO, Local Lodge No. 2530 and use its reasonable best efforts to assume the Assumed Collective Bargaining Agreement, and effective upon the Closing, Buyer shall have the sole responsibility for all Liabilities under the Assumed Collective Bargaining Agreement (arising on or after the Closing Date), including, without limitation, the obligation to make contributions on behalf of the Transferred Employees to the multiemployer plan identified in Section 5.8(k) of the Seller’s Disclosure

Schedule(the "Multiemployer Plan"). Buyer shall be obligated to contribute to the Multiemployer Plan for substantially the same number of contribution base units for which TDY had an obligation to contribute for the Business Employees covered by the Assumed Collective Bargaining Agreement immediately prior to the Closing Date (which obligation shall be interpreted in a manner consistent with Section 4204(a)(1)(A) of ERISA).

(ii) Buyer and TDY intend that the sale of assets under this Agreement shall constitute a sale of assets under Section 4204 of ERISA in order to avoid the immediate imposition of complete or partial withdrawal liability on TDY to the Multiemployer Plan with respect to the Tungsten Materials Business. Accordingly, Buyer and TDY agree to take all actions necessary to comply with Section 4204 of ERISA, including using reasonable good faith efforts to persuade the Multiemployer Plan that Section 4204 of ERISA applies, amending this Agreement if necessary to meet the specific requirements of the Multiemployer Plan to comply with Section 4204 of ERISA, and, subject to clause (iii) below, Buyer’s provision to the Multiemployer Plan for a period of five (5) plan years (defined by the Multiemployer Plan), commencing with the first plan year beginning after the Closing Date, of a bond issued by a corporate surety company that is an acceptable surety for purposes of Section 412 of ERISA, or an amount held in escrow by a bank or similar financial institution, satisfactory to the Multiemployer Plan (such bond or escrow shall be in satisfaction of Section 4204(a)(1)(B) of ERISA), and which bond or escrow shall be paid to the Multiemployer Plan if Buyer withdraws from the Multiemployer Plan, or fails to make a contribution when due, at any time during the first five plan years beginning after the Closing Date, and such bond or escrow (unless waived by the Multiemployer Plan) shall be in an amount equal to the greater of:

(A) the average annual contribution required to be made by TDY to the Multiemployer Plan with respect to the Tungsten Materials Business under the Assumed Collective Bargaining Agreement for the three plan years preceding the plan year in which the Closing Date occurs, and

(B) the annual contribution that TDY was required to make to the Multiemployer Plan with respect to the Tungsten Materials Business under the Assumed Collective Bargaining Agreement for the last plan year prior to the plan year in which the Closing Date occurs.

If, despite the reasonable good faith efforts of the parties to have the sale of the Tungsten Materials Assets treated as a sale of assets under Section 4204 of ERISA, the Multiemployer Plan nevertheless determines that Section 4204 of ERISA has not been satisfied, TDY shall be solely liable for any withdrawal liability incurred as of the Closing Date due to the sale

of the Tungsten Materials Assets hereunder and the following provisions of this Section 5.8(k) shall be inapplicable.

(iii) The cost of each bond, escrow or other surety device, if not waived, shall be paid by Buyer, and Buyer shall be the sole obligor thereunder. At Buyer’s sole discretion, and in lieu of the bond or escrow described in clause (ii) Buyer may prepare and submit to the Multiemployer Plan or the Pension Benefit Guaranty Corporation a request for a waiver, variance or exemption from the bond or escrow requirement, and TDY shall cooperate with Buyer in connection with such filing. Buyer shall provide written evidence to TDY that Section 4204(a)(1)(B) of ERISA has been timely satisfied or a waiver, variance, or exemption has been approved, as applicable.

(iv) In the event that any withdrawal liability is imposed on Buyer by the Multiemployer Plan during any period when TDY is primarily or secondarily liable for such liability pursuant to Section 5.8(k)(ii) or 5.8(k)(vi), Buyer shall use its reasonable good faith efforts to obtain and negotiate the lowest practicable amount thereof, subject to mutual agreement among Buyer and TDY (and in coming to an agreement, each of the parties agree to not unreasonably withhold or delay their consent).

(v) If Buyer withdraws from a Multiemployer Plan in a complete or partial withdrawal with respect to the Tungsten Materials Business and withdrawal liability is imposed upon and paid by Buyer with respect to such complete or partial withdrawal, Buyer shall be responsible for all withdrawal liability applicable under Title IV of ERISA to such complete or partial withdrawal.

(vi) To the extent required under Section 4204(a)(2) of ERISA, if Buyer withdraws from the Multiemployer Plan in a complete or partial withdrawal with respect to the Tungsten Materials Business during the first five (5) plan years beginning after the Closing Date, and Buyer fails to pay all or any portion of its withdrawal liability payments to such Multiemployer Plan, TDY shall be secondarily liable to such Multiemployer Plan for any withdrawal liability amount not paid by Buyer.

(l) Nothing in this Section 5.8 shall (i) amend, or be deemed to amend, any Benefit Plan or restrict Buyer’s or its Affiliates’ right to amend or terminate any benefit plan of Buyer or an Affiliate, as applicable, (ii) provide any Person not a party to this Agreement with any right, benefit or remedy with regard to any Benefit Plan or a right to enforce any provision of this Agreement, or (iii) require Buyer or its Affiliates to continue the employment of any Person, or otherwise interfere with Buyer’s (or its Affiliate’s) right to discharge, demote, or reassign any individual at any time.

(m) This Section 5.8 shall not apply to the employees of the Transferred Subsidiaries whose employment with the relevant Transferred Subsidiary shall continue

after Closing and whose terms and conditions of employment will be governed by applicable Contracts and applicable Laws.

(n) At the Closing the Transferred Subsidiaries shall have cash available in an amount equal to the accrued state pension obligations for employees in France, Germany and Italy (which as of June 30, 2013 was approximately $1,400,000) and such cash shall be deemed not to be a Cash Equivalent and such cash shall be transferred to Buyer at Closing.

Section 5.9 Real Property Matters. Prior to the Closing Date, TDY shall: (a) use commercially reasonable efforts to initiate, prosecute and complete in accordance with all governmental requirements, the Subdivision; provided, that if the Subdivision is not completed on or prior to the Closing Date, TDY shall enter into a short term lease and agreement of sale with Buyer at the Closing to effectuate the intent of the parties to transfer the parcel as soon as practicable following the completion of the Subdivision, in form and substance reasonably satisfactory to TDY and Buyer; (b) proceed diligently toward acquiring fee simple title to the real property located at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇, ▇▇▇▇▇▇▇ currently leased by TDY and for which the option to purchase has been exercised by TDY; and (c) exercise the purchase option related to the Leased Real Property located in Grant, Alabama and if requested by Buyer enter into negotiations with the landlord to extend the Lease related to such Leased Real Property on terms presented by Buyer.

Section 5.10 Post-Closing Access to Information. For a period of five (5) years from the Closing Date, except as prohibited by applicable Law, TDY and Buyer shall, subject to compliance by the other with the provisions of Section 5.13 and any Related Agreements, afford to each other and to each other's Representatives reasonable access and duplicating rights (with copying costs to be borne by the requesting party) during normal business hours to all books and records, documents and other information (collectively, "Information") within the knowledge, possession or control of the other party or its Affiliates solely to the extent relating to (a) in the case of requests by Buyer, the Tungsten Materials Business, Tungsten Materials Assets, Assumed Liabilities or Transferred Employees and (b) in the case of requests by TDY, the Excluded Businesses, the Excluded Assets or the Retained Liabilities, insofar in each case as such access is reasonably required by TDY or Buyer or any of their Subsidiaries or Affiliates for legitimate business reasons and does not violate any applicable Law or any confidentiality obligations applicable to TDY or Buyer or any of their Subsidiaries or Affiliates, as the case may be (and shall use reasonable efforts to cause persons or firms possessing relevant Information to give similar access) and, to the extent practicable, such Information is identified by the requesting party with reasonable specificity; provided, however, that no party shall be required to disclose any Information if (i) it believes in good faith that doing so presents a significant risk, based on an opinion of counsel (which can be inside counsel) of resulting in a loss of the ability to successfully assert a claim of Privilege or (ii) TDY or any of its Affiliates, on the one hand, and Buyer or any of its Subsidiaries, on the other hand, are adverse parties in a litigation (other than a litigation with respect to a claim for indemnification under this Agreement) and such information is reasonably pertinent thereto; provided, further, that, in the case of clause (i) above, the parties hereto shall reasonably cooperate in seeking to find a way to allow disclosure of such

information without resulting in a loss of the ability to successfully assert a claim of Privilege; provided, further, that TDY and its Affiliates shall not be required to provide Buyer or its Representatives with any information related to the Sale Process or TDY's or its Representatives' evaluation thereof, including projections, financial or other information related thereto other than projections, financial or other information prepared in the ordinary course of the Tungsten Materials Business without being primarily prepared for the Sale Process. Without limiting the generality of the foregoing, Information may be requested under this Section 5.10 for audit and accounting purposes and in connection with Actions, as well as for purposes of fulfilling disclosure and reporting obligations. Notwithstanding anything herein to the contrary, following Closing and for as long as such retention is required in accordance with TDY (or ATI’s) corporate records and information policies, as in effect as of the date hereof, or applicable Law (with the longer durational requirement to govern), Buyer shall retain all medical and exposure records of Business Employees and afford TDY and its Affiliates and Representatives with reasonable access to such medical and exposure records.

Section 5.11 Production of Witnesses and Individuals. From and after the Closing Date, TDY and Buyer shall use and shall cause their respective Subsidiaries to use reasonable efforts to make available to each other, upon written request, their respective officers, directors, employees and agents for fact finding, consultation and interviews and as witnesses to the extent that any such person may reasonably be required in connection with any Actions in which the requesting party may from time to time be involved relating to the conduct of the Tungsten Materials Business or the Excluded Businesses.

Section 5.13 Confidentiality.

(a) For a period of ten (10) years from the Closing Date, TDY and Buyer shall hold and shall cause their respective Affiliates to hold, and shall each use their reasonable best efforts to cause their respective Representatives to hold, in strict confidence and not to disclose or release without the prior written consent of the other party, any and all Confidential Information (as defined herein); provided, that the parties may disclose, or may permit disclosure of, Confidential Information (i) to their respective Representatives who have a need to know such information and are informed of their obligation to hold such information confidential to the same extent as is applicable to the parties hereto and in respect of whose failure to comply with such obligations, TDY or Buyer, as the case may be, will be responsible or (ii) if the parties hereto, their Affiliates or their Representatives are compelled to disclose any such Confidential Information by judicial or administrative process or, in the opinion of independent legal counsel, by other requirements of Law. Notwithstanding the foregoing, in the event that any demand or request for disclosure of Confidential Information is made pursuant to clause (ii) above, TDY or Buyer, as the case may be, shall promptly notify the other of the existence of such request or demand and shall provide the other a reasonable opportunity to seek an appropriate protective order or other remedy, which both parties will reasonably cooperate in obtaining (each at their own expense). In the event that such appropriate protective order or other remedy is not obtained, the party who is required to disclose such Confidential Information shall furnish, or cause to be furnished, only that portion of the Confidential Information that is legally required to be disclosed. As used in this Section 5.13, "Confidential Information" shall mean all proprietary technical, economic, environmental, operational, financial and/or other business Information or material of one party which, prior to or following the Closing Date, has been disclosed by TDY or its Affiliates, on the one hand, or Buyer or its Affiliates, on the other hand, in written, oral (including by recording), electronic, or visual form to, or otherwise has come into the possession of, the other, in each case including pursuant to the access provisions of Section 5.10 hereof or any other provision of this Agreement or any Related Agreement, (A) in the case of TDY and its Affiliates and Representatives, to the extent relating to the Tungsten Materials Business or the Tungsten Materials Assets prior to the Closing or (B) in the case of Buyer and its Affiliates and Representatives, to the extent relating to the Excluded Assets, the Retained Liabilities or the Excluded Businesses, including (a) ideas and concepts for existing products, processes and services; (b) specifications for products, Equipment and processes; (c) manufacturing and performance specifications and procedures; (d) engineering drawings and graphs; (e) technical, research and engineering data; (f) formulations and material specifications; (g) laboratory studies and benchmark tests; (h) service and operation manuals; (i) quality assurance policies, procedures and specifications; (j) evaluation and/or validation studies; (k) pending patent applications; (l) all other know-how, methodology, procedures, techniques and trade secrets related to research, engineering, development and manufacturing; and (m) business information, including marketing and development plans, forecasts, research and development agreements, and customer and vendor information (except to the extent that such Information can be shown to have been (1) in the public domain through no fault of such party or its Affiliates (including, in the case of TDY, any of the Retained Subsidiaries or, in the case of Buyer, any of its Subsidiaries) or (2) lawfully acquired

from other sources by the party (or its Affiliates) to which it was furnished including pursuant to this Agreement or the Related Agreements; provided, however, in the case of (2) that such sources did not provide such Information in breach of any confidentiality or other legal obligations). Notwithstanding the foregoing, nothing herein shall prevent (1) ATI or its Subsidiaries or Affiliates or their respective Representatives from disclosing or using any Confidential Information used or held for use in any Excluded Business or (2) Buyer or its Affiliates or their respective Representatives from disclosing or using any Confidential Information used or held for use in the Tungsten Materials Business from and after the Closing.

(c) Notwithstanding anything to the contrary set forth herein, (i) TDY and its Affiliates, on the one hand, and Buyer and its Affiliates, on the other hand shall be deemed to have satisfied their obligations hereunder with respect to Confidential Information if they exercise the same degree of care (but no less than a reasonable degree of care) as they take to preserve confidentiality for their own similar Information and (ii) confidentiality obligations provided for in any agreement between TDY or any of its Affiliates (or Buyer or any of its Affiliates with respect to the Tungsten Materials Business), on the one hand and any employee of TDY or any of its Affiliates, or Buyer or any of its Affiliates, on the other hand shall remain in full force and effect. Confidential Information of TDY and its Affiliates, on the one hand, or the Tungsten Materials Business, on the other hand, in the possession of and used by the other as of the Closing Date may continue to be used by TDY or its Affiliates, or Buyer or its Affiliates, as the case may be, in the operation of their businesses, so long as the Confidential Information is maintained in confidence and not disclosed in violation of this Agreement. Such continued right to use may not be transferred to any third party (other than an Affiliate of a party hereto) unless the third party purchases all or substantially all of the business and Assets in one transaction or in a series of related transactions for which or in which the relevant Confidential Information is used or employed.

(f) Notwithstanding the foregoing in this Section 5.13, to the extent that a Related Agreement or another Contract pursuant to which a party hereto is bound provides that certain Confidential Information shall be maintained confidential on a basis that is more protective of such Confidential Information or for a longer period of time than provided for in this Section 5.13, then the applicable provisions contained in such Related Agreement or other Contract shall control with respect thereto.

Section 5.14 Non-Competition.

(a) Commencing on and for a period of three (3) years following the Closing Date, TDY shall not, and shall cause ATI and the Subsidiaries of ATI not to, develop, manufacture, market or sell the Products (the "Prohibited Activities").

(b) Notwithstanding the foregoing, the parties agree that nothing herein shall prohibit TDY or ATI or any of their respective Subsidiaries from:

(i) acquiring or investing in any Person, or the assets thereof, if less than ten percent (10%) of the gross revenues, assets and income of such Person or assets (based on such Person's latest annual audited consolidated financial statements) are generated directly from the Prohibited Activities;

(ii) acquiring or investing in any Person, or the assets thereof, if ten percent (10%) or more than ten percent (10%), but not more than thirty percent (30%) of the gross revenues, assets and income of such Person or assets (based on such Person's latest annual audited consolidated financial statements) are generated directly from the Prohibited Activities; provided, that within one (1) year of such acquisition, TDY, ATI or any of their respective Subsidiaries enter into a definitive agreement to divest themselves of all or substantially all of the assets or operations so acquired that are engaged in any of the Prohibited Activities (and use commercially reasonable efforts to consummate such transaction within such one (1) year period);

(iii) acquiring, solely as an investment, securities of any Person traded on any national securities exchange if TDY, ATI or their respective Subsidiary, as applicable, is not a controlling Person of, or a member of a group which controls, such Person and does not, directly or indirectly, own five percent (5%) of the outstanding voting power of such Person; or

(iv) acquiring or investing in any equity interest in any Person through any employee benefit plan of TDY, ATI or any of their respective Subsidiaries.

(c) The parties agree that, notwithstanding anything to the contrary in Section 5.13(a), the provisions of Section 5.13(a) shall not prohibit (i) TDY or any of its Subsidiaries or Affiliates from performing under any Contract or Shared Contract or owning or operating any other Asset that constitutes a Tungsten Materials Asset which is not transferred, conveyed or assigned to Buyer or one of its Subsidiaries as of the Closing Date or (ii) TDY or any of its Subsidiaries or Affiliates from performing its obligations under this Agreement or any Related Agreement.

(d) The term "Products" shall mean the following: (i) carbide tool systems, specialty abrasives, carbide burrs and routers and thread cutting and thread rolling tools for use in metal cutting and metal finishing; (ii) rough mold, semi-finished and finished cemented tungsten heavy alloy components; and (iii) tungsten powder, tungsten carbide powder, coarse tungsten powder, crystalline tungsten powder, granulated tungsten powder, prepared tungsten powder, and tungsten heavy alloy blends.

Section 5.15 Mail and Other Communications; Accounts.

(a) After the Closing Date, each of TDY and its Affiliates and Buyer and its Affiliates may receive mail, packages and other communications (including electronic communications) properly belonging to the other (or the other's Affiliates). Accordingly, at all times after the Closing Date, each of TDY and Buyer authorizes the other and their

respective Affiliates to receive and open all mail, packages and other communications received by it and not unambiguously intended for the other party (or its Affiliates) or any of the other party's (or its Affiliates') officers or directors, and to retain the same to the extent that they relate to the Tungsten Materials Business (in the case of receipt by Buyer and its Affiliates) or the Excluded Businesses (in the case of receipt by TDY and its Affiliates), or to the extent that they do not relate to the Tungsten Materials Business (in the case of receipt by Buyer and its Affiliates) or the Excluded Businesses (in the case of receipt by TDY and its Affiliates), the receiving party shall promptly after becoming aware thereof refer, forward or otherwise deliver such mail, packages or other communications (or, in case the same relate to both the Tungsten Materials Business and the Excluded Businesses, copies thereof) to the other party. The provisions of this Section 5.15 are not intended to, and shall not be deemed to, constitute an authorization by either TDY or Buyer to permit the other to accept service of process on its behalf, and neither party is or shall be deemed to be the agent of the other for service of process purposes.

(b) All payments and reimbursements received by TDY or its Affiliates in connection with or arising out of the Tungsten Materials Business, the Tungsten Materials Assets or the Assumed Liabilities after the Closing shall be held by such Person in trust for the benefit of Buyer and, immediately upon receipt by such Person of any such payment or reimbursement, such Person shall pay over to Buyer the amount of such payment or reimbursement, without right of set off.

(c) All payments and reimbursements received by Buyer or its Affiliates in connection with or arising out of the Excluded Assets, Retained Liabilities or Excluded Businesses, after the Closing shall be held by such Person in trust for the benefit of TDY and, immediately upon receipt by such Person of any such payment or reimbursement such person shall pay over to TDY the amount of such payment or reimbursement without right of set off.

Section 5.16 Compliance with WARN Act and Similar Statutes. Buyer agrees that it shall, and shall cause its Subsidiaries to, comply with the Worker Adjustment and Retraining Notification Act of 1988 (the "WARN Act") and any applicable state, local and foreign plant closing and layoff law as it relates to any site of employment of the Tungsten Materials Business. Buyer agrees to, and shall cause its Subsidiaries to, indemnify, defend and hold harmless TDY and its Affiliates from and against any and all Losses which TDY and its Affiliates may incur in connection with any Action or claim of violation brought against TDY

and any Affiliate under the WARN Act or any state, local and foreign plant closing and layoff law, which relate, in whole or in part, to actions taken by Buyer or any of its Subsidiaries following the Closing Date with regard to any site of employment of the Tungsten Materials Business. TDY shall take all actions required under the WARN Act in connection with the termination of the Transferred Employees by TDY or its Affiliates prior to, or in connection with, the Closing.

Section 5.17 Shared Contracts.

(a) With respect to Shared Contractual Liabilities pursuant to, under or relating to a given Shared Contract, such Shared Contractual Liabilities shall, unless otherwise allocated pursuant to this Agreement or a Related Agreement, be allocated between TDY and Buyer as follows:

(i) If a Liability is incurred exclusively in respect of the Tungsten Materials Business or the Excluded Businesses, such Liability shall be allocated to Buyer (in respect of the Tungsten Materials Business) or TDY (in respect of the Excluded Businesses);

(ii) If a Liability cannot be so allocated under clause (i) above, such Liability shall be allocated to TDY or Buyer, as the case may be, based on the relative proportions of total benefit received (over the term of the Shared Contract remaining as of the Closing Date, measured as of the date of the allocation) by the Tungsten Materials Business or the Excluded Business under the relevant Shared Contract. Notwithstanding the foregoing, each of TDY and Buyer shall be responsible for any or all Liabilities arising from its (or its Subsidiary's) breach of the relevant Shared Contract to which this Section 5.17 otherwise pertains; provided, however, that each of TDY and Buyer shall be entitled to indemnification from the other for the portion of any Liabilities arising from any breach of the relevant Shared Contract by the other party (or its Subsidiary), which indemnification shall be separate from and not subject to the limitations set forth in Section 8.4.

(b) If TDY or any Retained Subsidiary, on the one hand, or Buyer or any of its Subsidiaries, on the other hand, receives any benefit or payment which under any Shared Contract was intended for the other, TDY and Buyer will use their respective reasonable best efforts to, and to cause their respective Subsidiaries to, deliver such benefit or payment to the other party.

(c) Notwithstanding anything to the contrary herein, the parties agree that the Shared Contracts listed on Section 5.17(c)(i) of the Seller's Disclosure Schedule shall not be deemed to be Tungsten Materials Assets hereunder (the "Excluded Shared Contracts"). Without limiting the foregoing, the parties have determined that it is advisable that certain Shared Contracts, which are identified on Section 5.17(c)(ii) of the Seller's Disclosure Schedule, be separated into separate Contracts between the appropriate third party and either the Excluded Businesses or the Tungsten Materials Business. The parties

agree to cooperate and provide reasonable assistance prior to the Closing (with no obligation on the part of either party to pay any costs or fees with respect to such assistance) in effecting the separation of such Shared Contracts. If such Shared Contracts are not separated at Closing, the parties agree to continue to provide each other with reasonable cooperation and assistance in effecting the separation of such Shared Contracts and shall treat the same as Shared Contracts or take such reasonable steps as are necessary to provide each party the benefit of such Contracts.

Section 5.18 Obligations Regarding Non-Assignable Assets.

(a) Notwithstanding anything else in this Agreement to the contrary, unless and until such license, consent, approval or amendment described below is no longer required or has been obtained, this Agreement and the Related Agreements shall not constitute an agreement to assign, license, sublicense, lease, sublease, convey or transfer at the Closing any Tungsten Materials Assets or any claim or right or any benefit arising thereunder or resulting therefrom as to which consent or approval from any Person (including any and all licenses to be granted by, and any and all consents and approvals of, Governmental Authorities) to assignment, license, sublicense, lease, sublease, conveyance or transfer thereof or amendment thereof is required but has not been obtained as of the Closing Date (such Tungsten Materials Assets, a "Delayed Tungsten Materials Assets"); provided, however, to the extent not inconsistent with the terms of any Delayed Tungsten Materials Assets or applicable Law, the parties shall treat Buyer as the owner thereof for Tax purposes as of the Closing Date; provided, further, that, except as otherwise expressly provided herein, neither TDY or any of its Affiliates nor Buyer or any of its Affiliates shall be required to commence any litigation or offer or pay any money or otherwise grant any accommodation (financial or otherwise) to any third party. Without limiting the generality of Section 5.3 and Section 5.4, TDY and Buyer shall use, and cause each of their Subsidiaries to use, commercially reasonable efforts to obtain any such license, consent, approval or amendment, including after the Closing Date. Upon obtaining the requisite licenses, consents or approvals, unless otherwise provided in the Transition Services Agreement, such Delayed Tungsten Materials Assets shall be transferred and assigned to Buyer hereunder at no cost to Buyer without additional consideration therefor.

(b) In the event and to the extent that, prior to the Closing, TDY or any Retained Subsidiary is unable to obtain a license, consent, approval or amendment required to assign, license, sublicense, lease, sublease, convey or transfer any Delayed Tungsten Materials Assets to Buyer, then following the Closing, TDY shall, and shall cause the Retained Subsidiaries to, use commercially reasonable efforts to, in each case, subject to the terms of the Transition Services Agreement, (i) continue to hold, and to the extent required by the terms applicable to such Delayed Tungsten Materials Assets, operate such Delayed Tungsten Materials Asset in all material respects in the ordinary course of business consistent with past practice and taking into account the transactions contemplated by this Agreement, (ii) cooperate in any arrangement, reasonable and lawful as to TDY and Buyer, designed to provide to Buyer or its Subsidiaries the benefits

arising under such Delayed Tungsten Materials Assets, including accepting such reasonable direction as Buyer shall request of TDY or its Affiliates, and (iii) enforce at Buyer's request, or allow Buyer and its Affiliates to enforce in a commercially reasonable manner, any rights of TDY or its Affiliates, as applicable, under such Delayed Tungsten Materials Assets against the other party or parties thereto; provided, however, that the costs and expenses incurred by TDY or its Affiliates at Buyer's request shall be borne by Buyer. Subject to the terms of the Transition Services Agreement, TDY shall, and shall cause the Retained Subsidiaries to, without further consideration therefor, pay and remit to Buyer promptly all monies, rights and other consideration received in respect of such performance. Subject to the terms of the Transition Services Agreement, Buyer shall pay, perform and discharge fully, promptly when due, all of the obligations of TDY or the Retained Subsidiaries in respect of such performance, and Buyer shall be responsible for all Assumed Liabilities related thereto and indemnify TDY Indemnified Parties for all Losses arising out of any actions (or omissions to act) of TDY or any Retained Subsidiary arising out of such performance or taken at the direction of Buyer or any of its Subsidiaries.

(c) Notwithstanding anything else set forth in this Section 5.18, neither TDY nor any other of its Affiliates shall be required to take any action that may, in the good faith judgment of TDY or such Affiliate, (i) result in a violation of any obligation which TDY or any such Affiliate has to any third party or (ii) violate applicable Law.

(d) Buyer agrees that TDY and its Affiliates shall not have any liability whatsoever arising out of or relating to, the failure to obtain any consents, approvals or licenses that may have been or may be required in connection with the transactions contemplated by this Agreement or because of the default under or acceleration or termination of any Contracts, Permits or Environmental Permits or other right or obligation, as a result thereof, other than as provided in Section 8.2. Buyer further agrees that no representation, warranty, covenant or other obligation of TDY contained herein shall be breached or deemed breached, and no condition to Buyer's obligations to consummate the transactions contemplated by this Agreement shall be deemed not satisfied, as a result of the failure to obtain any such consent, approval or license or as a result of any such default, acceleration or termination.

Section 5.19 Schedule Updates. If there occurs, after the date of this Agreement any fact or condition that renders any representation or warranty made by TDY in ARTICLE III untrue or if any fact or condition requires any change in the Seller's Disclosure Schedule delivered to Buyer at the time of execution of this Agreement, TDY will have the right, at its election, to deliver to Buyer at or before the Closing, and no later than seven (7) Business Days after learning of the occurrence of such fact or condition, a supplement to the Seller's Disclosure Schedule specifying any needed change. Any such supplement to Seller's Disclosure Schedule shall not be given effect for purposes of the conditions set forth in Section 7.3(a) or Section 7.3(d) herein; provided, however, that such supplement to Seller's Disclosure Schedule shall be given effect for purposes of determining whether there has been a breach of a representation and warranty for purposes of the indemnification provisions under Section 8.4(a) hereof; and

provided further, that Buyer expressly acknowledges that TDY shall be permitted to supplement the Seller's Disclosure Schedule to reflect the actions required by Section 5.9 (and any such supplement shall be given effect for purposes of Section 7.3(a), Section 7.3(d) and Section 8.4(a)).

Section 5.20 Related Agreements and Other Agreements. The parties hereto agree to enter into, and to cause each of their respective Subsidiaries to enter into, each of the Related Agreements to which it is contemplated to be a party at or prior to the Closing Date. To the extent there is a conflict between any of the provisions of this Agreement and any of the Related Agreements, the provisions of such Related Agreement shall control with respect to the subject matter thereof. Provided that it is not a condition to Closing, Buyer and TDY shall negotiate in good faith to enter into prior to the Closing Date in form and substance reasonably acceptable to the parties (i) a lease from Buyer to in favor of an Affiliate of TDY related to certain space currently leased by ATI ▇▇▇ ▇▇▇▇▇ in Madison, Alabama based on the material terms set forth in Schedule 3 of the Transition Services Agreement, (ii) a lease from Buyer in favor of an Affiliate of TDY related to certain space currently leased by ATI ▇▇▇ ▇▇▇▇▇ in Huntsville, Alabama based on the material terms set forth in Schedule 4 of the Transition Services Agreement, (iii) a Conversion Services Agreement related to conversion services to be performed by Buyer for an Affiliate of TDY based on the material terms set forth in Schedule 5 of the Transition Service Agreement and (iv) an arm’s length supply agreement pursuant to which the Tungsten Materials Business will supply powders to TDY and its Affiliates following Closing.

Section 5.21 Transfer of Permits and Environmental Permits. Buyer shall be responsible for preparing and submitting, on a timely basis, all filings required to effect the transfer of all Permits and Environmental Permits held in connection with the operation of the Tungsten Materials Assets to Buyer. A list of material Permits and material Environmental Permits to be transferred is set forth on Section 5.21(i) of the Seller's Disclosure Schedule. Schedule 5.21(ii) sets forth all Non-Transferable Permits that are material to the conduct of the Tungsten Materials Business. TDY shall cooperate with Buyer with respect to the preparation and filing of such transfer requests, including executing any necessary forms as required and providing information in TDY's possession to Buyer that is necessary or useful for any such transfer request. If any Permits or Environmental Permits cannot be transferred to Buyer prior to the Closing Date, TDY shall allow Buyer to operate under any such Permit or Environmental Permit until the same is obtained by Buyer, provided that Buyer uses good faith efforts to obtain any such Permits or Environmental Permits and indemnifies TDY for any fines, penalties or Environmental Claims to the extent resulting from Buyer’s operations under any TDY Permit or Environmental Permit.

Section 5.22 Financial Assurance. As required by applicable Law and as soon as practicable after Closing, but in any event no later than thirty (30) days after Closing unless otherwise allowed by applicable Law, Buyer shall submit to the appropriate regulatory agencies documentation satisfactory to such agencies that it has procured financial assurance, in compliance with applicable Laws, Permits and Environmental Permits, to replace the financial assurance provided by TDY or its Affiliates pursuant to such Laws, Permits and Environmental

Permits. A schedule of the financial assurance required to be obtained by Buyer is set forth on Section 5.22 of the Seller's Disclosure Schedule.

Section 5.23 Insurance. From and after the Closing Date, the Tungsten Materials Business, the Tungsten Materials Assets and Assumed Liabilities shall cease to be insured by TDY or its Affiliates' insurance policies or by any of their self-insured programs for Losses incurred after the Closing Date, and neither Buyer nor its Subsidiaries shall have any access, right, title or interest to or in any such insurance policies (including to all claims and rights to make claims and all rights to proceeds) on or after the Closing to cover any Losses incurred after the Closing Date related to the Tungsten Materials Assets or Assumed Liabilities or any Liability arising from the operation of the Tungsten Materials Business after the Closing Date. TDY or its Affiliates may, to be effective at the Closing, amend any insurance policies in the manner it deems appropriate to give effect to this Section 5.23. For Losses incurred prior to the Closing Date that are Assumed Liabilities related to Third Party Claims (whether arising prior to or following the Closing Date), and for which rights, if any, to insurance benefits and proceeds are being transferred in the Sale, TDY shall and shall cause its Affiliates to reasonably cooperate with Buyer to make available to Buyer the benefits, if any, that are being transferred in the Sale, under its third party insurance policies, including, if reasonably requested by Buyer, notifying the applicable insurers and seeking their acknowledgment or consent thereto; provided, however, that TDY and its Affiliates make no representations, warranties or covenants that any of their insurance policies provide coverage for any Assumed Liabilities or that the assignment of any insurance rights to Buyer in the Sale is or shall be valid, effective or enforceable. Buyer acknowledges that such policies, as well as other policies issued to TDY and/or its Affiliates, are or may be subject to various limitations, including self-insurance features, retrospectively-rated premiums, insurer insolvencies, impairment, erosion, exhaustion, and various settlements and/or releases that may impose defense, indemnification or other obligations on TDY or its Affiliates. Buyer further acknowledges that, if Buyer’s assertion of insurance rights transferred in the Sale gives rise to any material obligations, including any material obligations arising under any self-insurance features, such as deductibles, retentions or retrospectively-rated premiums, or to any defense or indemnification obligations related to insurance settlement(s), such material obligations shall be considered Assumed Liabilities.

ARTICLE VI

(c) Closing Certificate. TDY shall have furnished Buyer with such certificate signed by its Chief Financial Officer to the effect that the conditions set forth in Sections 7.3(a) and 7.3(b) hereof have been satisfied.

(d) No Material Adverse Effect. Since the date of this Agreement, there shall not have occurred and be continuing a Material Adverse Effect.

ARTICLE VIII
TERMINATION AND ABANDONMENT; INDEMNIFICATION

Section 8.1 Termination. This Agreement may be terminated at any time prior to the Closing:

(a) by mutual written consent of TDY and Buyer;

(b) by TDY or Buyer if the Closing shall not have occurred on or before December 15, 2013 (the "Outside Date"), provided, however, that the terminating party shall have fulfilled its obligations contained in Section 5.3 prior to exercising its right to termination hereunder; provided, further, that if on the Outside Date the conditions to the Closing set forth in Section 7.1(b) shall not have been satisfied but all other conditions to the Closing shall be satisfied or waived (other than those conditions that, by their nature, are to be satisfied at the Closing (provided such conditions would be satisfied as of such date)), then either party shall have the right to extend the Outside Date an additional 90 days by notifying the other party in writing of such election before the Outside Date; provided, further, that the right to terminate this Agreement under this Section 8.1(b) shall not be available to any party whose failure to fulfill any obligation under this Agreement shall have been the cause of, or shall have resulted in, the failure of the Closing to occur on or prior to such date;

(c) by TDY or Buyer if any Governmental Authority shall have issued an order, decree or ruling or taken any other action restraining, enjoining or otherwise prohibiting any material portion of the transactions contemplated hereunder and such order, decree, ruling or other action shall have become final and nonappealable; provided, however, that the terminating party shall have fulfilled its obligations contained in Section 5.3 prior to exercising its right to termination hereunder;

(d) by Buyer upon written notice to TDY, if there shall have been a material breach of any of the representations, warranties, agreements or covenants set forth in this Agreement on the part of TDY or the Share Sellers which has rendered the satisfaction of any conditions set forth in Section 7.3 incapable of fulfillment, such violation or breach has not been waived by Buyer, and the breach has not been cured within 30 days following Buyer's written notice of such breach and is not capable of being cured prior to the Outside Date; provided, however, that the right to terminate this Agreement under this Section 8.1(d), if not exercised, shall terminate 60 days following delivery of such written notice; provided, further, that the right to terminate this Agreement under this Section 8.1(d) shall not be available to Buyer if it is then in material breach of any representation, warranty, covenant, or other agreement contained herein;

(e) by TDY upon written notice to Buyer, if there shall have been a material breach of any of the representations, warranties, agreements or covenants set forth in this Agreement on the part of Buyer which has rendered the satisfaction of any conditions set forth in Section 7.2 incapable of fulfillment, such violation or breach has not been waived by TDY, and the breach has not been cured within 30 days following TDY's written notice of such breach and is not capable of being cured prior to the Outside Date; provided, however, that the right to terminate this Agreement under this Section 8.1(e), if not exercised, shall terminate 60 days following delivery of such written notice; provided, further, that the right to terminate this Agreement under this Section 8.1(e) shall not be available to TDY if it is then in material breach of any representation, warranty, covenant, or other agreement contained herein;

(f) by TDY upon written notice to Buyer, three (3) Business Days following such written notice if the Closing has not occurred prior thereto, if Buyer fails to consummate the Closing within three (3) Business Days of the satisfaction or waiver of the conditions set forth in Section 7.1 and Section 7.3 (other than those conditions that, by their nature, are to be satisfied at the Closing (provided such conditions would have been satisfied as of such date) or the failure of which to be satisfied is attributable primarily to a breach by Buyer of its representations, warranties, covenants or agreements contained in this Agreement); provided, further that Buyer shall not be entitled to terminate this Agreement during such three (3) Business Day period pursuant to this Section 8.1).

Notwithstanding the foregoing, each party agrees that it shall have no right to terminate this Agreement pursuant to Section 8.1(b) during the pendency of a legal proceeding by the other party for specific performance pursuant to Section 9.7.

Section 8.2 Procedure and Effect of Termination. In the event of termination of this Agreement pursuant to Section 8.1, written notice thereof shall forthwith be given to the other party, and, except as set forth in this Section 8.2, this Agreement shall terminate and be void and have no effect and the transactions contemplated hereby shall be abandoned; provided that if (x) such termination shall (I) result from the Intentional Breach of any representation, warranty, covenant or other agreement contained herein or (II) occur following an Intentional Breach or (y) the Intentional Breach of any representation, warranty, covenant or other agreement contained herein shall cause the Closing not to occur, then such breaching party shall be fully liable for any and all damages incurred or suffered by the other party as a result of such failure or breach; provided, further, that any failure by Buyer to consummate the Closing at any time at which TDY shall have the right to terminate this Agreement pursuant to Section 8.1(f) shall be deemed to be an Intentional Breach by Buyer. If this Agreement is terminated as provided herein:

(a) each party hereto will redeliver, and will cause its agents (including attorneys and accountants) to redeliver, all documents, work papers and other material of each party hereto relating to the transactions contemplated hereby, whether obtained before or after the execution hereof;

(b) all Information received by Buyer with respect to the business, operations, Assets or financial condition of ATI or its Subsidiaries shall remain subject to the Confidentiality Agreement; and

(c) notwithstanding the termination hereof, the Confidentiality Agreement and the following Sections of this Agreement shall remain in full force and effect: (i) Section 3.16 and Section 4.4 relating to brokers, (ii) the penultimate sentence of Section 5.2 relating to confidentiality matters, (iii) Section 9.13 relating to certain expenses, (iv) Section 8.1 and this Section 8.2 and (v) ARTICLE IX.

Section 8.3 Survival of Representations, Warranties and Covenants. Except in the case of claims based on fraud or intentional misconduct, the representations and warranties contained herein shall survive the Closing and shall thereupon terminate on the eighteen month anniversary of the Closing Date, except for (i) the Fundamental Representations, which shall survive the Closing forever and (ii) the Special Representations, which shall survive for the Special Representations Period. All covenants and agreements contained herein which by their terms contemplate actions or impose obligations following the Closing shall survive the Closing and remain in full force and effect in accordance with their terms; provided that, for the avoidance of doubt, (x) the obligations of Buyer to assume, and to indemnify TDY Indemnified Parties for, the Assumed Liabilities and (y) the obligations of TDY to retain, and indemnify Buyer Indemnified Parties for, the Retained Liabilities shall in each case survive the Closing indefinitely.

Section 8.4 Indemnification.

(a) From and after the Closing, and subject to Section 8.3 and this Section 8.4, TDY shall indemnify and hold harmless Buyer and its Subsidiaries and each of their

Affiliates and each of Buyer's, its Subsidiaries', and its Affiliates' respective officers, directors, employees, and agents (collectively, the "Buyer Indemnified Parties") from and against any Losses arising from or in connection with (i) the failure of TDY or the Share Sellers to duly perform or observe any covenant or agreement to be performed or observed by TDY or the Share Sellers pursuant to this Agreement (the remedy for which survives the Closing) or any Related Agreement, (ii) any of the Retained Liabilities, (iii) any breach of any representation of TDY set forth in ARTICLE III of this Agreement, or (iv) the Thoriated Powder Obligations.

(b) From and after the Closing, and subject to Section 8.3 and this Section 8.4, Buyer shall indemnify and hold harmless TDY, ATI and each of their respective Subsidiaries and Affiliates and each of TDY's, ATI’s, their Subsidiaries' and their Affiliates' respective officers, directors, employees, and agents (collectively, the "TDY Indemnified Parties") from and against any Losses arising from or in connection with (i) the failure of Buyer or any Buyer Designee to duly perform or observe any covenant or agreement to be performed or observed by Buyer or any Buyer Designee pursuant to this Agreement (the remedy for which survives the Closing) or any Related Agreement, (ii) any of the Assumed Liabilities (regardless of whether such Assumed Liabilities were assumed by Buyer or any Buyer Designee pursuant to Section 1.3), or (iii) any breach of any representation of Buyer set forth in ARTICLE IV of this Agreement.

(c) Any calculation of Losses for purposes of this Section 8.4 (including for purposes of determining the amount of Losses for purposes of sub-sections (h) and (i) below) shall be (i) net of any insurance or other third party recovery actually paid to the Indemnified Party (whether paid directly to such Indemnified Party or assigned by the Indemnifying Party to such Indemnified Party) and (ii) (x) increased to take into account any net Tax cost incurred by the Indemnified Party arising from the receipt or accrual of indemnity payments hereunder (grossed-up for such increase) and (y) reduced to take account of any net Tax benefit realized by the Indemnified Party arising from the deductibility of any such Losses or Taxes. Any indemnification payment hereunder shall initially be made without regard to clause (ii) of the immediately preceding sentence and shall be increased or reduced to reflect any such net Tax cost (including gross-up) or net Tax benefit only after the Indemnified Party has actually realized such cost or benefit. The amount of any increase or reduction hereunder shall be adjusted as necessary to reflect any final resolution with respect to the Indemnified Party's liability for Taxes and, if necessary, TDY or Buyer, as the case may be, shall make payments to the other to reflect such adjustment. Except as otherwise required by applicable Law, any indemnity payment under this Agreement shall be treated as an adjustment to the Final Purchase Price, for Tax purposes. Each of the parties shall notify the other parties if it receives notice that any Tax Authority proposes to treat any indemnity payment under this Agreement as other than an adjustment to the Final Purchase Price for Tax purposes. A party (and its Affiliates) shall not be deemed to have suffered a "Loss" with respect to an item to the extent such party was actually compensated therefor by reason of an increase in the amount otherwise paid to it or a reduction in the amount otherwise paid by it pursuant to Section 2.3 hereof.

(d) No Action or claim for Losses subject to indemnification under this Section 8.4 with respect to a breach of any representation, warranty, covenant or agreement contained in this Agreement shall be brought or made after the date on which such representation, warranty, covenant or agreement shall terminate pursuant to Section 8.3 hereof, regardless of when the facts underlying such claim are first discovered; provided, however, that any claim made after the Closing and prior to such termination date with reasonable specificity by the Indemnified Party to the Indemnifying Party shall survive (and be subject to indemnification) until it is finally and fully resolved.

(e) Notwithstanding any provision herein to the contrary, no indemnity may be sought hereunder in respect of (i) any Losses to the extent such Liability was taken into account in determining the Final Net Working Capital, or (ii) any claim for breach of any representation or warranty of TDY if (A) such claim is based on a fact or an event occurring prior to Closing (whether or not also occurring prior to the date of this Agreement) and (B) such fact or event was disclosed to Buyer prior to the Closing. For purposes of this Section 8.4(e), the term "disclosed" shall be understood to include only (I) the disclosures contained in the Seller's Disclosure Schedule and (II) information made available to Buyer in the Data Room prior to 5pm (Eastern time) on September 12, 2013 in such a way as to make reasonably apparent its relevance or applicability as a qualification or exception to a specific representation of TDY.

(f) (i) Upon receipt by a Buyer Indemnified Party or TDY Indemnified Party (the "Indemnified Party") of notice from a third party of any action, suit, proceeding, claim, demand or assessment against such Indemnified Party which might give rise to a claim for Losses under this Section 8.4, the Indemnified Party (or TDY or Buyer on behalf of an Indemnified Party) shall promptly give written notice thereof to the party from whom indemnification is sought (the "Indemnifying Party") setting forth, with reasonable specificity, the nature of and facts underlying each particular claim (including identification of all particular sections of this Agreement pursuant to which indemnification is being sought), a copy of any documentation received from the third party and an estimate of the Losses relating thereto; provided, however, that failure to give such notice shall not eliminate the right to indemnification provided hereunder except to the extent the Indemnifying Party shall have been materially prejudiced as a result of such failure. For the avoidance of doubt, notice by the Indemnified Party to the Indemnifying Party will not be made or include notification (formal or informal, written or oral) to any other Person or Governmental Authority, other than as specifically agreed in writing between the Parties or as may be required by applicable Law. Except as specifically provided in Section 8.4(k), the Indemnifying Party shall have the right, at its option, to assume the defense of, at its own expense and by its own counsel, any such matter as to which the Indemnified Party is seeking indemnification hereunder. If the Indemnifying Party shall, in accordance with the preceding sentence, undertake to compromise or defend any such asserted liability, it shall notify the Indemnified Party of its intention to do so, and the Indemnified Party shall agree to cooperate fully with the Indemnifying Party and its counsel in the compromise of, or defense against, any such asserted liability; provided, however, that the Indemnifying Party shall not settle any such

asserted liability without the written consent of the Indemnified Party (not to be unreasonably withheld) unless such settlement releases the Indemnified Party in connection with such matter and provides relief consisting solely of money damages borne by the Indemnifying Party. Notwithstanding an election of the Indemnifying Party to assume the defense of such action or proceeding, the Indemnified Party shall have the right to employ separate counsel and to participate in the defense of such action or proceeding. The Indemnifying Party shall bear the reasonable fees, costs and expenses of one such separate counsel pursuant to the preceding sentence in each jurisdiction (and shall pay such fees, costs and expenses at least quarterly), if, but only if, (i) the defendants in, or targets of, any such action or proceeding include both an Indemnified Party and the Indemnifying Party, and such Indemnified Party shall have reasonably concluded, based on the advice of counsel, that there is a material conflict of interest between the Indemnifying Party and the Indemnified Party with respect to such proceeding (in which case the Indemnifying Party shall not have the right to direct the defense of such action or proceeding on behalf of the Indemnified Party) or (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to such Indemnified Party to represent such Indemnified Party within a reasonable time after notice of the institution of such action or proceeding. In any event, the Indemnified Party and its counsel shall cooperate with the Indemnifying Party and its counsel and shall not assert any position in any proceeding inconsistent with that asserted by the Indemnifying Party.

(ii) Except as specifically provided in Section 8.4(k), if the Indemnifying Party does not undertake to compromise or defend any Third Party Claim pursuant to Section 8.4(f)(i) above, then the Indemnifying Party shall have the right to participate in any such defense at its sole cost and expense, but in such case, the Indemnified Party shall control the investigation and defense of the asserted liability; provided, however, that the Indemnified Party shall not consent to any settlement of a Third Party Claim without the prior written consent of the Indemnifying Party; provided, further, that the Indemnifying Party may, at its option, elect at any time to assume and control the defense against such Third Party Claim. The Indemnifying Party's decision to allow the Indemnified Party to take the lead with respect to any indemnity obligation of the Indemnifying Party shall not limit, expand or otherwise affect the Indemnifying Party's obligation to indemnify the Indemnified Party with respect to any such indemnity obligation, and if an Indemnified Party settles a Third Party Claim it is defending pursuant to this Section 8.4(f)(ii) without obtaining the Indemnifying Party's written consent to such settlement in violation of the immediately preceding sentence, then the Indemnifying Party shall be relieved of its indemnification obligations hereunder with respect to such Third Party Claim.

(iii) In the event any Indemnified Party has an indemnification claim against any Indemnifying Party under this Agreement that does not involve a claim by a third party, promptly after becoming aware of any facts or circumstances which the Indemnified Party believes have given or would reasonably be expected to give rise to a right of indemnification pursuant to this Agreement, the Indemnified Party shall deliver

notice of such claim to the Indemnifying Party in writing setting forth, with reasonable specificity, the nature of and facts underlying each particular claim (including identification of all particular sections of this Agreement pursuant to which indemnification is being sought) and an estimate of the Losses relating thereto. The failure by any Indemnified Party to so notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party, except to the extent that the Indemnifying Party has been materially prejudiced by such failure. If the Indemnifying Party disputes its liability with respect to such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through negotiations, such dispute shall be resolved by litigation in the appropriate court of competent jurisdiction.

(g) The indemnification provisions of this Agreement (i) shall be the sole and exclusive remedy (other than (A) as set forth in Section 5.17(a)(ii) and (B) injunctive relief or specific performance as contemplated by Section 9.7) following the Closing with respect to the matters covered by this Agreement or related to the Sale, including any breach or non-fulfillment of any representation, warranty, agreement, covenant or any other obligation contained in this Agreement or any Related Agreement, (ii) shall apply without regard to, and shall not be subject to, any limitation by reason of set-off, limitation or otherwise and (iii) are intended to be comprehensive and not to be limited by any requirements of Law concerning prominence of language or waiver of any legal right under any Law (including rights under any workers compensation statute or similar statute conferring immunity from suit). In furtherance of the foregoing, except for claims arising from fraud or intentional misconduct, each party hereby waives, to the fullest extent permitted by applicable Law, any and all other rights, claims and causes of action (including rights of contributions, if any) known or unknown, foreseen or unforeseen, which exist or may arise in the future, that it may have against TDY or any of its Affiliates or Buyer or any of its Affiliates, as the case may be, arising under or based upon any Law (including any such Law relating to environmental matters (including Environmental Laws) or arising under or based upon any securities Law, common Law or otherwise). The obligations of the parties set forth in this Section 8.4 shall be conditioned upon the Closing having occurred. Without limiting the generality of the foregoing, in no event shall any party, its successors or permitted assigns be entitled to claim or seek rescission of the transactions contemplated by this Agreement and the Related Agreements. Without limiting the foregoing, but subject to the terms of this Agreement, Buyer, for itself and its Affiliates and on behalf of their respective successors and assigns, does hereby irrevocably release, hold harmless and forever discharge TDY and its Affiliates and their respective Representatives from any and all Environmental Claims resulting from or arising out of or in connection with the Tungsten Materials Assets or the Tungsten Materials Business other than claims arising from (i) a breach of the representations or warranties set forth in Section 3.12, (ii) the Retained Liabilities or (iii) fraud or intentional misconduct. In furtherance of, but subject to, the foregoing, Buyer, for itself and on behalf of its Affiliates, successors and assigns, hereby irrevocably waives any and all rights and benefits with respect to such Environmental Claims (other than claims arising from fraud or intentional misconduct) that it now has, or in the future

may have conferred upon it by virtue of any Law or common law principle, in each case, which provides that a general release does not extend to claims which a party does not know or suspect to exist in its favor at the time of executing the release, if knowledge of such claims would have materially affected such party's settlement with the obligor. In this connection, Buyer hereby acknowledges that it is aware that factual matters now unknown to it and TDY or any of their respective Affiliates with respect to environmental conditions at, on, in or underneath any Real Property may have given, or hereafter may give, rise to Environmental Claims that have not been made prior to the date of this Agreement or will not be made prior to the Closing Date, and Buyer further agrees that the release set forth in this Section 8.4 has been negotiated and agreed upon in light of that awareness, and Buyer, for itself and its Affiliates and on behalf of their respective successors and assigns, nevertheless hereby intends irrevocably to release, hold harmless and forever discharge TDY and its Affiliates and their respective Representatives from all such Environmental Claims (other than claims arising from fraud or intentional misconduct).

(h) Notwithstanding anything to the contrary set forth herein, neither TDY nor Buyer shall be required to provide indemnification for Losses (other than with respect to claims for Losses based on breach of Fundamental Representations or fraud or intentional misconduct) under Sections 8.4(a)(iii) and 8.4(b)(iii) to the Buyer Indemnified Parties or TDY Indemnified Parties, respectively, (i) for any individual item or series of related items where the Loss relating thereto is less than Twenty-Five Thousand U.S. Dollars ($25,000) (the "De Minimis Claim Threshold") or (ii) in respect of each individual item where the Loss relating thereto is equal to or greater than the De Minimis Claim Threshold, unless the aggregate amount of all such Losses incurred by the Buyer Indemnified Parties or TDY Indemnified Parties, as applicable, with respect to such breaches (in the aggregate), exceeds $7,562,500 (the "Basket"), in which case the obligation to provide indemnification under Sections 8.4(a)(iii) and 8.4(b)(iii) to the Buyer Indemnified Parties or TDY Indemnified Parties, as the case may be, shall only apply with respect to such amounts that are in excess of the Basket.

(i) Notwithstanding anything to the contrary set forth herein, the maximum aggregate amount of indemnifiable Losses that may be recovered from TDY or Buyer, respectively, arising out of or resulting from the causes enumerated in Sections 8.4(a)(iii) and 8.4(b)(iii), as applicable, shall not exceed $60,500,000 in the aggregate (other than with respect to claims for Losses based on breach of Fundamental Representations or fraud or intentional misconduct, which shall be limited to the Final Purchase Price).

(j) Notwithstanding anything to the contrary set forth herein, for purposes of this Section 8.4 only, the representations and warranties of TDY shall not be deemed qualified by any reference to materiality, Material Adverse Effect, or similar qualification.

(k) (i) Notwithstanding anything to the contrary set forth herein, TDY's indemnity obligation pursuant to Section 8.4(a)(iii) with respect to any breach of TDY's

representations and warranties set forth in Section 3.12 shall be subject to the following limitations:

(A) if the cost of Cleanup or for correcting a non-compliance with the Environmental Law subject to indemnity by TDY is increased after the Closing due to an act by any Person other than TDY or its Affiliates or any of their respective employees, agents, consultants or representatives, TDY shall not be responsible for any such increase in costs incurred;

(B) TDY shall not be responsible for any capital improvements and repairs and modifications to capital improvements associated with any property;

(C) TDY shall not be responsible for any costs, including costs of Cleanup and for corrective actions, to the extent such costs are incurred due to (A) any change in Environmental Laws occurring after the Closing Date; (B) any change resulting or arising from the closure, sale, modification, excavation or construction of, or at, the Real Property, except for any modification, excavation or construction undertaken by Buyer in the ordinary course of business; (C) any change in use of the facilities from manufacturing to any other use; or (D) implementation of any Cleanup or corrective action that is not conducted to achieve the least stringent applicable Remediation Standards in the most effective and commercially reasonable manner; and

(D) TDY shall not be responsible for costs of Cleanup, corrective action or other Losses arising out of or related to any investigation, compliance or risk audit, assessment, study or other remedial or corrective action that any Buyer Indemnified Party voluntarily initiates, performs or causes to be performed by any Person or Governmental Authority (i.e., any investigation, compliance or risk audit, assessment, study or other remedial or corrective action that any Buyer Indemnified Party initiates, performs or causes to be performed which is not required by any Environmental Law or first initiated and required by a Governmental Authority).

(ii) With respect to any indemnity obligation of TDY pursuant to Section 8.4(a)(iii) for any breach of TDY's representations and warranties set forth in Section 3.12, to the extent such indemnity obligation (1) relates to a Third Party Claim, TDY shall have the right to defend, compromise and settle any and all such Third Party Claims, and (2) relates to (i) the investigation or Cleanup of any exposure to or Release of Hazardous Substances or (ii) the investigation of or corrective action for any potential or actual non-compliance with Environmental Laws, TDY shall have the right to take the lead and implement any such investigation, corrective action or Cleanup, which right shall include, without limitation, access to the Real Property if necessary to undertake

such work. Buyer may, at its own expense, remain involved in the performance of any action respecting clauses (1) and (2) of the preceding sentence (except to the extent that such involvement would unreasonably interfere with the performance of the work), and TDY shall promptly provide copies to Buyer of all notices, correspondence, draft reports and final reports related to such matter. However, for the avoidance of doubt, Buyer's involvement as provided in this paragraph shall not include communications or contact of any nature whatsoever with any Person or Governmental Authority except as specifically pre-approved in writing by TDY. No Cleanup by TDY shall include the use of any remediation technique or method which imposes any unreasonable restrictions on Buyer’s use of the Real Property for the Tungsten Materials Business unless Buyer pre-approves such restriction in writing (such pre-approval not to be unreasonably withheld or delayed). For purposes of the foregoing sentence, “unreasonable restrictions” shall not include (A) restrictions on the use or extraction of groundwater, (B) the placement or maintenance of engineered barriers where floors, foundations or other manmade surfaces exist as of the Closing, or (C) deed restrictions limiting the use of the Real Property to commercial or industrial purposes. TDY shall undertake any such work required herein in a manner designed to minimize any disruption, to the extent reasonably practicable, with the conduct of operations at the Real Property. Buyer shall agree to allow access to conduct any of the work contemplated herein and shall fully cooperate with TDY in the performance of the work.

(iii) If TDY declines to exercise its right to defend, compromise and settle any Third Party Claim or to take the lead and implement any investigation, corrective action or Cleanup under this Section 8.4(k), Buyer may (1) defend, compromise and settle any such Third Party Claim, and (2) take the lead and implement any such investigation, corrective action or Cleanup, and Buyer shall allow TDY, at TDY's sole expense, to remain involved in the performance of any action respecting clauses (1) and (2) above; provided, however, that Buyer shall not consent to any settlement of any such Third Party Claim without the prior written consent of TDY (which consent shall not be unreasonably withheld, conditioned or delayed); provided, further, that TDY may, at its option, elect at any time to assume and control the defense against such Third Party Claim. TDY's decision to allow Buyer to take the lead with respect to any indemnity obligation of TDY shall not limit, expand or otherwise affect TDY's obligation to indemnify Buyer with respect to any such indemnity obligation of TDY. Buyer shall promptly provide copies to TDY of all notices, correspondence, draft reports and final reports related to such matter.

(iv) If Buyer or its Affiliates (1) settles any Third Party Claim, or (2) initiates contact with any Governmental Authority (except in response to any inquiry initiated by any Governmental Authority), in relation to any matter that is or could be an indemnity obligation of TDY pursuant to Section 8.4(a)(iii) for any breach of TDY's representations and warranties set forth in Section 3.12 without obtaining TDY's prior written consent (which consent shall not be denied if the reporting is required by applicable Environmental Law), then TDY shall be relieved of its indemnification

obligations hereunder with respect to such matter, and Buyer shall indemnify TDY for any Losses resulting from such settlement or contract.

(l) Notwithstanding anything to the contrary set forth herein, TDY shall not be required to provide indemnification for Losses under Section 8.4(a)(iv) to the Buyer Indemnified Parties unless the aggregate amount of all such Losses incurred by the Buyer Indemnified Parties with respect to Section 8.4(a)(iv) (in the aggregate) exceeds $250,000, in which case the obligation to provide indemnification under Section 8.4(a)(iv) to the Buyer Indemnified Parties shall only apply with respect to such amounts that are in excess of $250,000. Notwithstanding anything to the contrary set forth herein, (A) the maximum aggregate amount of Losses that may be recovered from TDY arising out of or resulting from the causes enumerated in Section 8.4(a)(iv) shall not exceed $13,000,000 in the aggregate, (B) TDY shall not be responsible for any Losses or any other obligations incurred by the Buyer Indemnified Parties for any Losses arising out of, or otherwise related to, the Thoriated Powder Obligations and/or TDY’s operation of the thoriated tungsten powder product line at the Huntsville, Alabama facility on or after the fifth anniversary of the Closing Date; provided, however, that any claim made prior to such fifth anniversary shall survive (and be subject to indemnification) until it is fully and finally resolved, and (C) Section 8.4(a)(iv) shall be the sole and exclusive remedy of the Buyer Indemnified Parties for any Losses arising out of, or otherwise related to, the Thoriated Powder Obligations and/or TDY’s operation of the thoriated tungsten powder product line at the Huntsville, Alabama facility (and the Buyer Indemnified Parties shall not be entitled to any other claims for Losses under Section 8.4 or otherwise, including for a breach or alleged breach of the representation in Section 3.12, related to the Thoriated Powder Obligations and/or TDY’s operation of the thoriated tungsten powder product line at the Huntsville, Alabama facility).

(m) In the event the Buyer has an indemnification claim against TDY under Section 8.4(a)(iv), promptly after becoming aware of any facts or circumstances which the Buyer believes have given or would reasonably be expected to give rise to a right of indemnification pursuant to Section 8.4(a)(iv), the Buyer shall deliver reasonably prompt notice of such claim to TDY in writing setting forth, with reasonable specificity, the nature of and facts underlying each particular claim and an estimate of the Losses relating thereto. With respect to any indemnity obligation of TDY pursuant to Section 8.4(a)(iv), TDY shall have the right, upon notice to Buyer within 30 days of receipt of notice of a claim from Buyer, to take the lead and implement any such investigation, corrective action or Cleanup in accordance with applicable Environmental Laws and Environmental Permits, which right shall include, without limitation, reasonable access to the Real Property located at Huntsville, Alabama if necessary to undertake such work. TDY shall comply with, and shall cause any third parties performing the work to comply with, Buyer’s reasonable standard policies and procedures related to its facilities and third party service providers. Buyer may, at its own expense, remain involved in the performance of any action related to the preceding sentence (except to the extent that such involvement would unreasonably interfere with the performance of the work), and TDY shall promptly provide copies to Buyer of all notices, correspondence, draft reports

and final reports related to such matter. TDY shall provide a monthly accounting of any work undertaken pursuant to any indemnification claim under Section 8.4(a)(ii) during any period such work is ongoing. TDY shall undertake any such work required herein in a manner designed to minimize any disruption, to the extent reasonably practicable, with the conduct of operations at the Real Property and shall not undertake the work in a manner that adversely effects Buyer’s use of the Real Property (other than as relates to the investigation, corrective action or Cleanup of the Thoriated Powder Obligations and/or Buyer’s operation of the thoriated tungsten powder product line at the Huntsville, Alabama facility). Subject to Section 8.4(l), TDY’s obligation hereunder shall be considered satisfied with respect to any indemnification claim hereunder when TDY receives and provides to Buyer a no further action letter or its equivalent from the applicable Governmental Authority. Buyer shall reasonably cooperate with TDY in the performance of the work, but shall be reimbursed by TDY for any expenditures incurred as a result of such cooperation. If TDY declines to take the lead and implement any investigation, corrective action or Cleanup under this Section 8.4(m), Buyer may take the lead and implement any such investigation, corrective action or Cleanup, and Buyer shall allow TDY, at TDY's sole expense, to remain involved in the performance of any action; provided, however, that Buyer shall not consent to any settlement, if applicable, without the prior written consent of TDY (which consent shall not be unreasonably withheld, conditioned or delayed);. TDY's decision to allow Buyer to take the lead with respect to any indemnity obligation of TDY shall not limit, expand or otherwise affect TDY's obligation to indemnify Buyer with respect to any such indemnity obligation of TDY. Buyer shall promptly provide copies to TDY of all notices, correspondence, draft reports and final reports related to such matter.

(b) To the extent that any party hereto has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each such party hereby irrevocably (i) waives such immunity in respect of its obligations with respect to this Agreement, and (ii) submits to the personal jurisdiction of any court described in Section 9.9(a).

of interest or any other purposes as a result thereof. Buyer hereby agrees that, in the event that a dispute arises between Buyer or any of its Affiliates and ATI or any of its Affiliates, K&L Gates LLP may represent ATI or any such Affiliate in such dispute even though the interests of ATI or such Affiliate may be directly adverse to Buyer or any of its Affiliates (including any Transferred Subsidiary) and even though K&L Gates LLP may have represented the Tungsten Materials Business or a Transferred Subsidiary in a matter substantially related to such dispute, and Buyer hereby waives, on behalf of themselves and each of its Affiliates, any conflict of interest in connection with such representation by K&L Gates LLP.
