Returns relating to the Steel Business, and shall pay (or cause such TimkenSteel Entity to pay) all Taxes shown to be due and payable on such Tax Returns. 

Section 2.02 Tax Return Procedures for Mixed Business Tax Returns. 

(a) Timken shall prepare all Mixed Business Tax Returns consistent with historical practice, the Opinion, and the Tax Representation Letter
unless otherwise required by Law or agreed to in writing by TimkenSteel. In the event that there is no historical practice for reporting a particular item or matter, Timken shall determine the reporting of such item or matter provided that such
determination is, in the reasonable opinion of Timken, at least more likely than not to be sustained. In connection with the preparation of any Mixed Business Tax Return, TimkenSteel will assist and cooperate with Timken with respect to
Timken’s preparation of each Mixed Business Tax Return, including assisting Timken in the preparation of a pro forma Tax Return for TimkenSteel and any TimkenSteel Entity to be used in determining the TimkenSteel Allocable Portion with respect
to such Mixed Business Tax Return. 
 (b) In connection with any Mixed Business Tax Return, no later than 30 days prior to the Due Date of
each such Tax Return, Timken shall make available or 

  
 11 








 
cause to be made available drafts of such Tax Return (together with all related work papers) and a document determining the TimkenSteel Allocable Portion of Taxes with respect to such Mixed
Business Tax Return to TimkenSteel. The failure of Timken to make available any such materials described in the preceding sentence to TimkenSteel within the time frame described in the preceding sentence shall not relieve TimkenSteel of any
obligation which it may have to Timken under this Agreement except to the extent that TimkenSteel is actually prejudiced by such failure. TimkenSteel shall have access to any and all data and information necessary for the preparation of all such
Mixed Business Tax Returns and the Parties shall cooperate fully in the preparation and review of such Tax Returns. Subject to the preceding sentence, no later than 15 days after receipt of such Mixed Business Tax Returns (and related documents),
TimkenSteel shall have a right to object to such Mixed Business Tax Return (or items with respect thereto, including the TimkenSteel Allocable Portion with respect to such Mixed Business Tax Return) by written notice to Timken; such written notice
shall contain such disputed item (or items) and the basis for its objection. TimkenSteel shall pay to Timken no later than five days prior to the Due Date of each such Tax Return the TimkenSteel Allocable Portion of Taxes shown as due and payable on
such Mixed Business Tax Return (net of any prepayment made against such amount). 
 (c) With respect to a Mixed Business Tax Return
delivered by Timken to TimkenSteel pursuant to Section 2.02(b), if TimkenSteel does not object by proper written notice described in Section 2.02(b), such Mixed Business Tax Return and the calculation of the TimkenSteel Allocable Portion
with respect thereto shall be deemed to have been accepted and agreed upon, and to be final and conclusive, for purposes of this Section 2.02(c). If TimkenSteel does object by proper written notice described in Section 2.02(b), Timken and
TimkenSteel shall act in good faith to resolve any such dispute as promptly as practicable; provided, however, that, notwithstanding anything to the contrary contained herein, if Timken and TimkenSteel have not resolved the disputed item or items by
the day five days prior to the Due Date of such Mixed Business Tax Return, such Tax Return shall be filed as prepared pursuant to this Section 2.02(a) (revised to reflect all initially disputed items that Timken and TimkenSteel have agreed upon
prior to such date). In the event that a Mixed Business Tax Return is filed that includes any disputed item for which proper notice was given pursuant to Section 2.02(b) that was not finally resolved and agreed upon, such disputed item (or
items) shall be resolved in accordance with Section 8.01 (interpreted without regard to the requirement that the Accounting Firm render a determination no later than the Due Date of the Tax Return at issue). In the event that the resolution of
such disputed item (or items) in accordance with Section 8.01 with respect to a Mixed Business Tax Return is inconsistent with such Mixed Business Tax Return as filed, Timken (with cooperation from TimkenSteel, if necessary) shall, as promptly
as practicable, amend such Tax Return to properly reflect the final resolution of the disputed item (or items). In the event that the amount of Taxes shown to be due and owing on a Mixed Business Tax Return is adjusted as a result of a resolution
pursuant to this Section 2.02(c), proper adjustment shall be made to the amounts previously paid or required to be paid in a manner that reflects such resolution. 

  
 12 








 Section 2.03 Expenses. Except as provided otherwise herein or in the Separation Agreement,
each Party shall bear its own expenses incurred in connection with this Article 2.

ARTICLE III. PAYMENT OF TAXES AND INDEMNIFICATION. 

Section 3.01 Payment and Indemnification by Timken. Timken shall pay, and shall indemnify and hold the TimkenSteel Group harmless from
and against, without duplication, (a) all Timken Taxes, (b) all Taxes incurred by TimkenSteel or any TimkenSteel Entity by reason of the breach by Timken of any of its representations, warranties or covenants hereunder, and (c) any
external costs and expenses related to the foregoing (including reasonable attorneys’ fees and expenses but excluding any expenses described in Section 2.03).

(c) any external costs and expenses related to the foregoing (including reasonable attorneys’ fees and expenses but excluding any expenses described in Section 2.03). 

Section 3.03 Timing of Tax Payments. Unless otherwise provided in this Agreement, in the event that a Party (the “Indemnifying
Party”) is required to make a payment to another Party (the “Indemnified Party”) pursuant to this Article 3, the Indemnified Party shall deliver written notice of the payments to the Indemnifying Party, including proof of
payment to the Taxing Authority, in accordance with Section 8.19 on the last day of the calendar quarter in which the obligation giving rise to the indemnification payment must be satisfied, and the Indemnifying Party shall be required to make
payment to the Indemnified Party within 10 days after notice of such payment is delivered to the Indemnifying Party. 
 Section 3.04
Characterization of and Adjustments to Payments. For all Tax purposes, Timken and TimkenSteel agree to treat (a) any payment required by this Agreement or (b) any indemnity payments required by the Contribution Agreement or Separation
Agreement (other than payments pursuant to Section 8.03) as either a contribution by Timken to TimkenSteel or a distribution by TimkenSteel to Timken, as the case may be, occurring immediately prior to the Distribution Date. Except as otherwise
provided, any payment under this Agreement shall be decreased to take into account any reduction in taxable income of the Indemnified Party arising from the payment by the Indemnified Party of such indemnified liability and increased to take into
account any inclusion in taxable income of the Indemnified Party arising from the receipt of such indemnity payment if there is any such increase notwithstanding the first sentence of this 

  
 13 








 
Section 3.04 (collectively, “Tax Benefits”). Any Tax Benefit shall be determined (i) using the highest applicable marginal U.S. federal corporate income tax rate in
effect at the time of the determination (and excluding any state income tax effect of such inclusion or reduction) and (ii) assuming that the Indemnified Party will be liable for Taxes at such rate, the Indemnified Party has sufficient taxable
income to use any tax deduction, and has no other relevant Tax Attributes at the time of the determination. For the avoidance of doubt, the previous two sentences of this Section 3.04 do not apply to any payments made pursuant to
Section 6.03. 
 ARTICLE IV. REFUNDS, CARRYBACKS, AMENDMENTS AND TAX ATTRIBUTES. 

Section 4.01 Refunds 
 (a)
Except as provided in Section 4.02, Timken shall be entitled to all Refunds of Taxes with respect to which Timken would be liable for payment under Article 3 if such Taxes were paid after the Distribution Date, and TimkenSteel shall be entitled
to all Refunds of Taxes with respect to which TimkenSteel would be liable for payment under Article 3 if such Taxes were paid after the Distribution Date. A Party receiving a Refund to which the other Party is entitled pursuant to this Agreement
shall pay to the other Party the amount to which such other Party is entitled within 10 days after the receipt of the Refund. 
 (b)
Notwithstanding Section 4.01(a), to the extent that a Party applies or causes to be applied an overpayment of Taxes as a credit toward or a reduction in Taxes otherwise payable by such Party (or a Taxing Authority requires such application in
lieu of a Refund) and such overpayment of Taxes, if received as a Refund, would have been payable by such Party to the other Party pursuant to this Section 4.01, such Party shall pay such amount to the other Party no later than the Due Date of
the Tax Return for which such overpayment is applied to reduce Taxes otherwise payable. 
 (c) In the event of an Adjustment relating to
Taxes for which one Party is or may be liable pursuant to Article 3 would have given rise to a Refund but for an offset against the Taxes for which the other Party is or may be liable pursuant to Article 3 (the “Benefited Party”),
then the Benefited Party shall pay to the other Party within 10 days of the Final Determination of such Adjustment an amount equal to the lesser of (a) the amount of such hypothetical Refund or (b) the amount of such reduction in the Taxes
of the Benefited Party, in each case plus interest at the rate set forth in Section 6621(a)(1) of the Code on such amount for the period from the filing date of the Tax Return that would have given rise to such Refund to the payment date to the
other Party. 
 (d) To the extent that the amount of any Refund under this Section 4.01 is later reduced by a Taxing Authority or as
the result of a Tax Proceeding, such reduction shall be allocated to the Party that was entitled to such Refund pursuant to this Section 4.01 and an appropriate adjusting payment shall be made by such Party to the other Party if the other Party
originally paid the Refund to such Party. For the avoidance of doubt, this Section 4.01(d) is intended to make whole the other Party that was not entitled to the Refund. 

  
 14 








 Section 4.02 Carrybacks. 

(a) Subject to Timken’s discretion to file an amended Tax return under Section 4.03, each Party is permitted (but not required) to
carry back (or to cause its Subsidiaries to carry back) a loss, credit, or other Tax Attribute realized in a Post-Closing Period or a Straddle Period to a Pre-Closing Period or a Straddle Period; provided, however, that if such carryback would
reasonably be expected to adversely impact the other Party (including through an increase in Taxes or a loss or reduction in the utilization of a loss, credit, or other Tax Attribute regardless of whether or when such loss, credit, or other Tax
Attribute otherwise would have been used), such carryback shall not be permitted without first obtaining the prior written consent of such other Party, which consent shall not be unreasonably withheld or delayed. 

(b) Refunds for Carrybacks. 

(i) Subject to Sections 4.02(c) and 4.02(d), in the event that any member of the TimkenSteel Group chooses to (or is required to under
applicable Law), and is permitted to under Sections 4.02(a) and 4.03, carry back a loss, credit, or other Tax Attribute to a Mixed Business Tax Return, Timken shall cooperate with TimkenSteel and such member in seeking from the appropriate Taxing
Authority any Refund that reasonably would result from a permitted carryback (including by filing an amended Tax Return at TimkenSteel’s cost and expense). TimkenSteel (or such member) shall be entitled to any Refund realized by any member of
the Timken Group or TimkenSteel Group as a result of the carryback. 
 (ii) Subject to Sections 4.02(c) and 4.02(d), in the event that any
member of the Timken Group chooses to (or is required to under applicable Law), and is permitted to under Sections 4.02(a) and 4.03, carry back a loss, credit, or other Tax Attribute to a Mixed Business Tax Return, TimkenSteel shall cooperate with
Timken and such member in seeking from the appropriate Taxing Authority any Refund that reasonably would result from a permitted carryback (including by filing an amended Tax Return at Timken’s cost and expense). Timken shall be entitled to any
Refund realized by any member of the TimkenSteel Group or Timken Group as a result of the carryback. 
 (c) Except as otherwise provided by
applicable Law, if any loss, credit or other Tax Attribute of the Bearings Business and the Steel Business both would be eligible to be carried back or carried forward to the same Pre-Closing Period or Straddle Period (had such carryback been the
only carryback to such taxable period) (such amount for each of Bearings Business and the Steel Business separately referred to as the “Carryback Amount” and the sum of both amounts returned to as the “Aggregate Carryback
Amount”), any Refund resulting therefrom shall be allocated between Timken and TimkenSteel proportionately based on the ratio of the Bearings Business Carryback Amount to the Aggregate Carryback Amount and the Steel Business Carryback
Amount to the Aggregate Carryback Amount, respectively. Appropriate adjustments to the allocation of any Refund under the preceding sentence shall be made if the carryback results in any additional Tax Attributes being allocated to the Timken Group
or the TimkenSteel Group (for example, under the regulations applicable to U.S. federal 

  
 15 








 
consolidated income tax returns) to the extent necessary to cause the Timken Group, on the one hand, and the TimkenSteel Group, on the other hand, to proportionately benefit from such carryback.

 (d) To the extent the amount of any Refund under this Section 4.02 is later reduced by a Taxing Authority or a Tax Proceeding, such
reduction shall be allocated to the Party to which such Refund was allocated pursuant to this Section 4.02. 
 Section 4.03
Amended Tax Returns. 
 (a) Mixed Business Tax Returns. Timken shall, in its sole discretion, be permitted to amend, or to cause TimkenSteel
or any TimkenSteel Entity to amend (and TimkenSteel shall, if Timken so chooses, amend or cause the applicable TimkenSteel Entity to amend), any Mixed Business Tax Return; provided, however, that unless otherwise required by a Final Determination,
Timken shall not be permitted to so amend any such Mixed Business Tax Return to the extent that any such amendment or filing (i) would reasonably be expected to materially adversely impact TimkenSteel (including through an increase in Taxes or
a loss or reduction of a Tax Attribute regardless of whether or when such Tax Attribute otherwise would have been used), (ii) would be inconsistent with historical practice, or (iii) would be inconsistent with the Opinion or Tax
Representation Letter, in each case without the prior written consent of TimkenSteel, which consent shall not be unreasonably withheld or delayed. If requested in writing by TimkenSteel at least 60 days prior to the expiration of the applicable
statute of limitations, Timken shall amend any Mixed Business Tax Return to reflect changes proposed by TimkenSteel; provided, however, that TimkenSteel shall reimburse Timken for all reasonable out-of-pocket costs and expenses incurred by Timken in
amending such Mixed Business Tax Return; provided, further, that unless otherwise required by a Final Determination, Timken shall not be required to so amend any such Mixed Business Tax Return to the extent that any such amendment (A) would
reasonably be expected to materially adversely impact Timken (including through an increase in Taxes or a loss or reduction of a Tax Attribute regardless of whether or when such Tax Attribute otherwise would have been used), (B) would be
inconsistent with historical practice, or (C) would be inconsistent with the Opinion or Tax Representation Letter. 
 (b) Single
Business Tax Returns. 
 (i) Timken. Timken shall, in its sole discretion, be permitted to amend (or cause or permit to be amended) any
Single Business Tax Return relating to the Bearings Business. 
 (ii) TimkenSteel. TimkenSteel shall, in its sole discretion, be permitted
to amend (or cause or permit to be amended) any Single Business Tax Return relating to the Steel Business. 
 Section 4.04 Tax
Attributes. 
 (a) Tax Attributes arising in a Pre-Closing Period will be allocated to (and the benefits and burdens of such Tax Attribute
will inure to) the Timken Group and 

  
 16 








 
the TimkenSteel Group in accordance with historical practice (including historical methodologies for making corporate allocations), the Code, Treasury Regulations, and any applicable state, local
and foreign Law. For the avoidance of doubt, the CAT Credit will be allocated in the manner agreed to by the State of Ohio. Timken and TimkenSteel shall jointly determine the allocation of such Tax Attributes arising in Pre-Closing Periods as soon
as reasonably practicable following the Distribution Date, and shall compute all Taxes for a Post-Closing Period and Straddle Period consistently with that determination unless otherwise required by a Final Determination. 

(b) Except as otherwise provided herein, to the extent that the amount of any Tax Attribute is later reduced or increased by a Taxing
Authority or as a result of a Tax Proceeding, such reduction or increase shall be allocated to the Party to which such Tax Attribute was allocated pursuant to Section 4.04(a). 

(c) Notwithstanding anything to the contrary in this Agreement, Timken shall at all times be entitled to any Tax deduction or credit, as the
case may be, relating to (i) the exercise of Timken Common Shares compensatory stock options, (ii) restricted stock that has vested (in whole or in part) on or prior to the Distribution Date, or (iii) restricted stock with respect to
Timken Common Shares. TimkenSteel shall be entitled to any Tax deduction or credit, as the case may be, relating to (A) the exercise of TimkenSteel Common Shares compensatory stock options or (B) restricted stock with respect to
TimkenSteel Common Shares. To the extent any Tax deduction that is described in either of the first two sentences of this Section 4.04(c) and claimed by the Party to whom the deduction is allocated under this section 4.04(c) is disallowed to
such Party and a Taxing Authority makes a determination that the other Party is entitled to such deduction, the Party denied such deduction shall notify the other Party of the receipt of such determination, promptly after receipt thereof, and the
Party for which the determination allows the Tax deduction shall pay to the other Party the amount of the Tax Benefit arising therefrom. 

ARTICLE V. TAX PROCEEDINGS 

Section 5.01 Notification of Tax Proceedings. Within 10 days after a Controlling Party (or its Subsidiary) becomes aware of the
commencement of a Tax Proceeding that may give rise to Taxes for which an Interested Party is responsible pursuant to Article 3, such Controlling Party shall provide notice to the Interested Party of such Tax Proceeding, and thereafter shall
promptly forward or make available to the Interested Party copies of notices and communications relating to such Tax Proceeding. The failure of the Controlling Party to provide notice to the Interested Party of the commencement of any such Tax
Proceeding within such 10-day period or promptly forward any further notices or communications shall not relieve the Interested Party of any obligation which it may have to the Controlling Party under this Agreement except to the extent that the
Interested Party is actually prejudiced by such failure. 
 Section 5.02 Tax Proceeding Procedures. The Controlling Party, in its sole
discretion, and at its own expense, shall be entitled to control, administer, contest, litigate, compromise and settle any Adjustment proposed, asserted or assessed pursuant to any 

  
 17 








 
Tax Proceeding and any such actions taken by the Controlling Party shall be made diligently and in good faith; provided that the Controlling Party shall (a) keep the Interested Party
informed in a timely manner of all actions proposed to be taken by the Controlling Party and shall permit the Interested Party to comment in advance on the Controlling Party’s oral or written submissions with respect to such Tax Proceeding,
(b) prepare all correspondence or filings to be submitted to any Taxing Authority or judicial authority in a manner consistent with the Tax Return, which is the subject of such Adjustment, as filed and timely provide the Interested Party with
copies of any such correspondence or filings for the Interested Party’s prior review and comment and (c) provide the Interested Party with written notice reasonably in advance of, and the Interested Party shall have the right to attend and
participate in, any formally scheduled meetings with any Taxing Authority or hearings or proceedings before any judicial authority with respect to such Adjustment. Furthermore, the Controlling Party may not settle or otherwise resolve a Tax
Proceeding with respect to an Adjustment that would reasonably be expected to impact the Tax liability of an Interested Party without the consent of such Interested Party, such consent not to be unreasonably withheld; provided that the Controlling
Party shall be permitted to settle or otherwise resolve a Tax Proceeding if and when the only unsettled issue of such Tax Proceeding relates to an Adjustment for which an Interested Party has consent rights pursuant to the previous clause, but has
not consented to settlement. 
 Section 5.03 Tax Proceeding Cooperation. Each Party shall act in good faith and use its reasonable best
efforts to cooperate fully with the other Party (and its Subsidiaries) in connection with such Tax Proceeding and shall provide or cause its Subsidiaries to provide such information to each other as may be necessary or useful with respect to such
Tax Proceeding in a timely manner, identify and provide access to potential witnesses, and other persons with knowledge and other information within its control and reasonably necessary to the resolution of the Tax Proceeding. 

ARTICLE VI. TAX-FREE STATUS OF THE TRANSACTIONS 

Section 6.01 Representations and Warranties. 

(a) TimkenSteel. TimkenSteel hereby represents and warrants or covenants and agrees, as appropriate, that: 

(i) it has examined (A) the Opinion, (B) the Tax Representation Letter, and (C) any other materials delivered or deliverable by
Timken or TimkenSteel in connection with the rendering by Counsel of the Opinion (all of the foregoing, collectively, the “Tax Materials”) ; 

(ii) the facts presented and the representations made therein, to the extent descriptive of the TimkenSteel Group (including the business
purposes for the Distribution as described in the Opinion and the other Tax Materials to the extent that they relate to the TimkenSteel Group and the plans, proposals, intentions and policies of the TimkenSteel Group), are, or will be from the time
presented or made through and including the Distribution Date and thereafter as relevant, true, correct and complete in all respects ; 

  
 18 








 (iii) it knows of no fact (after due inquiry) that may negate the Tax-Free Status of the
Transactions ; and 
 (iv) neither it, nor any of its Subsidiaries, has any plan or intent to take any action which is inconsistent with any
statements or representations made in the Tax Materials. 
 (b) Timken. Timken hereby represents and warrants or covenants and agrees, as
appropriate, that: 
 (i) it has examined the Tax Materials ; 

(ii) it has delivered complete and accurate copies of the Tax Materials to TimkenSteel, and the facts presented and the representations made
therein, to the extent descriptive of the Timken Group (including the business purposes for the Distribution as described in the Opinion, and the other Tax Materials to the extent that they relate to the Timken Group and the plans, proposals,
intentions and policies of the Timken Group), are, or will be from the time presented or made through and including the Distribution Date and thereafter as relevant, true, correct and complete in all respects ; 

(iii) it knows of no fact (after due inquiry) that may negate the Tax-Free Status of the Transactions ; and 

(iv) neither it, nor any of its Subsidiaries, has any plan or intent to take any action which is inconsistent with any statements or
representations made in the Tax Materials. 
 Section 6.02 Limits on Proposed Acquisition Transactions and Other Transactions During
Restriction Period. 
 (a) During the Restriction Period, Timken and TimkenSteel: 

(i) shall continue and cause to be continued the active conduct of the Bearings Business and the Steel Business, in each case taking into
account Section 355(b)(3) of the Code and as conducted immediately prior to the Distribution; 
 (ii) shall not voluntarily dissolve,
liquidate, or partially liquidate (including any action that is treated as a liquidation for federal income Tax purposes); 
 (iii) shall
not enter into any Proposed Acquisition Transaction or, approve any Proposed Acquisition Transaction, or permit any Proposed Acquisition Transaction to occur; 

(iv) shall not redeem or otherwise repurchase (directly or through an Affiliate) any stock, or rights to acquire stock, except to the extent
such repurchases 

  
 19 








 
satisfy Section 4.05(1)(b) of Revenue Procedure 96-30 as in effect prior to the amendment of such Revenue Procedure by Revenue Procedure 2003-48 (provided, however, that the fact that any
such redemption or repurchase satisfies Section 4.05(1)(b) of Revenue Procedure 96-30 shall not prevent such redemption or repurchase from being considered, or taken into account for purposes of another transaction constituting, a Proposed
Acquisition Transaction, in which case clause (iii) shall apply); 
 (v) shall not amend its articles of incorporation (or other
organizational documents), or take any other action or approve or permit the taking of any action, whether through a stockholder vote or otherwise, affecting the relative voting rights of the common shares (including through the conversion of any
common shares into another class of capital stock); 
 (vi) shall not issue shares of a new class of nonvoting stock; 

(vii) shall not merge or consolidate with any other Person; provided, however, that if Timken or TimkenSteel acquires equity of another Person
in a transaction that is not otherwise described in clauses (i) through (vi), (viii), or (ix) of this Section 6.02(a), then the merger or consolidation of such Person with and into Timken or TimkenSteel (with Timken or TimkenSteel
surviving), as applicable, shall not constitute a merger or consolidation described in this clause (vii); 
 (viii) shall not sell,
transfer, or otherwise dispose of or agree to, sell, transfer or otherwise dispose of (including in any transaction treated for U.S. federal income Tax purposes as a sale, transfer or disposition, and including any sale, transfer or other
disposition to an Subsidiary or otherwise) assets (including, any shares of common shares of a Subsidiary) that, in the aggregate, constitute more than 35% of its consolidated gross or net assets. The foregoing sentence shall not apply to
(A) sales, transfers, or dispositions of assets in the Ordinary Course of Business, (B) any cash paid to acquire assets from an unrelated Person in an arm’s-length transaction, (C) any assets transferred to a Person that is
disregarded as an entity separate from the transferor for U.S. federal income Tax purposes or (D) any mandatory or optional repayment (or pre-payment) of any indebtedness of such company. The percentages of consolidated gross and net assets
sold, transferred, or otherwise disposed of, shall be based on the fair market value of the gross or net assets, as the case may be, of Timken and TimkenSteel, as applicable, as of the Distribution Date. For purposes of this
Section 6.02(a)(viii), a merger of Timken or TimkenSteel with and into any Person shall constitute a disposition of all of the assets of Timken or TimkenSteel, respectively; and 

(ix) shall not take any other action or actions (including any action or transaction that would be reasonably likely to be inconsistent with
any representation made in the Tax Materials) which in the aggregate (and taking into account any other transactions described in this Section 6.02(a)) would be reasonably likely to have the effect of causing or permitting one or more Persons
(whether or not acting in concert) to acquire directly or indirectly stock representing a Fifty-Percent or Greater Interest in Timken or TimkenSteel or otherwise jeopardize the Tax-Free Status of the Transactions. 

  
 20 








 (b) Notwithstanding the restrictions imposed by Section 6.02(a), during the Restriction
Period, Timken and TimkenSteel shall be permitted to take such action or one or more actions set forth in the foregoing clauses (i) through (ix), if, prior to taking any such actions, the Party taking the action (the “Acting
Party”) set forth in the foregoing clauses (i) through (ix) shall (1) have received a favorable private letter ruling from the IRS, or a ruling from another appropriate Taxing Authority that confirms that such action or
actions will not affect the Tax-Free Status of the Transactions, taking into account such actions and any other relevant transactions in the aggregate (a “Post-Distribution Ruling”), in form and substance satisfactory to the other
Party (the “Non-Acting Party”), or (2) have received an Unqualified Tax Opinion that confirms that such action or actions will not affect the Tax-Free Status of the Transactions, or (3) the Non-Acting Party shall have
waived in writing the requirement to obtain such ruling or opinion. In determining whether a ruling or opinion is satisfactory, the Non-Acting Party shall exercise its discretion, in good faith, solely to preserve the Tax-Free Status of the
Transactions and may consider, among other factors, the appropriateness of any underlying assumptions or representations used as a basis for the ruling or opinion and the Non-Acting Party’s views on the substantive merits of such ruling or
opinion. The Acting Party shall provide a copy of the Post-Distribution Ruling or the Unqualified Tax Opinion described in this paragraph to the Non-Acting Party as soon as practicable prior to taking or failing to take any action set forth in the
foregoing clause (i) through (ix). The Acting Party shall bear all costs and expenses of securing any such Post-Distribution Ruling or Unqualified Tax Opinion and shall reimburse the Non-Acting Party for all reasonable out-of-pocket costs and
expenses that the Non-Acting Party may incur in good faith in seeking to obtain or evaluate any such Post-Distribution Ruling or Unqualified Tax Opinion. 

Section 6.03 Section 336(e) Elections. Pursuant to Treasury Regulation sections 1.336-2(h)(1)(i) and 1.336-2(j), Timken and
TimkenSteel agree that Timken shall make a timely protective election under Section 336(e) of the Code and the Treasury Regulations issued thereunder for TimkenSteel and each TimkenSteel Affiliate that is a domestic corporation for U.S. federal
income Tax purposes with respect to the Distribution (a “Section 336(e) Election”). It is intended that a Section 336(e) Election will have no effect unless the Distribution is a “qualified stock disposition,” as
defined in Treasury Regulation section 1.336(e)-1(b)(6), either because (a) the Distribution is not a transaction described in Treasury Regulations section 1.336-1(b)(5)(i)(B) or (b) Treasury Regulation Section 1.336-1(b)(5)(ii)
applies to the Distribution. If and to the extent that there is a violation of the Tax-Free Status of the Transaction, and the resulting Taxes (including any Taxes attributable to the Section 336(e) Election) are considered Timken Taxes (rather
than TimkenSteel Taxes), then, to that extent, Timken shall be entitled to quarterly payments from TimkenSteel equal to the actual Tax savings arising from the step-up in Tax basis resulting from the Section 336(e) Election, determined using a
“with and without” methodology (treating any deductions or amortization attributable to the step-up in tax basis resulting from the Section 336(e) Election as the last items claimed for any taxable year, including after the
utilization of any available net operating loss carryforwards), and less a reasonable charge for administrative expenses necessary to secure the Tax savings. 

  
 21 








 ARTICLE VII. COOPERATION 

Section 7.01 General Cooperation. 

(a) The Parties shall each cooperate fully (and each shall cause its respective Subsidiaries to cooperate fully) with all reasonable requests
in writing (“Information Request”) from another Party hereto, or from an agent, representative or advisor to such Party, in connection with the preparation and filing of Tax Returns (including the preparation of Tax Packages),
claims for Refunds, Tax Proceedings, and calculations of amounts required to be paid pursuant to this Agreement, in each case, related or attributable to or arising in connection with Taxes of any of the Parties or their respective Subsidiaries
covered by this Agreement and the establishment of any reserve required in connection with any financial reporting (a “Tax Matter”). Such cooperation shall include the provision of any information reasonably necessary or helpful in
connection with a Tax Matter (“Information”) and shall include, without limitation, at each Party’s own cost: 
 (i)
the provision of any Tax Returns of the Parties and their respective Subsidiaries, books, records (including information regarding ownership and Tax basis of property), documentation and other information relating to such Tax Returns, including
accompanying schedules, related work papers, and documents relating to rulings or other determinations by Taxing Authorities; 
 (ii) the
execution of any document (including any power of attorney) in connection with any Tax Proceedings of any of the Parties or their respective Subsidiaries, or the filing of a Tax Return or a Refund claim of the Parties or any of their respective
Subsidiaries; 
 (iii) the use of the Party’s reasonable best efforts to obtain any documentation in connection with a Tax Matter; and

 (iv) the use of the Party’s reasonable best efforts to obtain any Tax Returns (including accompanying schedules, related work
papers, and documents), documents, books, records or other information in connection with the filing of any Tax Returns of any of the Parties or their Subsidiaries. 

Each Party shall make its employees, advisors, and facilities available, without charge, on a reasonable and mutually convenient basis in connection with the
foregoing matters. 
 Section 7.02 Retention of Records. Timken and TimkenSteel shall retain or cause to be retained all Tax Returns,
schedules and workpapers, and all material records or other documents relating thereto in their possession, until 60 days after the expiration of the applicable statute of limitations (including any waivers or extensions thereof) of the taxable
periods to which such Tax Returns and other documents relate or until the expiration of any additional period that any Party reasonably requests, in writing, with respect to specific material records or documents. A Party intending to destroy any
material records or documents shall provide the other Party with reasonable advance 

  
 22 








 
notice and the opportunity to copy or take possession of such records and documents. The Parties hereto will provide notice to each other in writing of any waivers or extensions of the applicable
statute of limitations that may affect the period for which the foregoing records or other documents must be retained. 
 ARTICLE VIII.
MISCELLANEOUS 
 Section 8.01 Dispute Resolution. 

(a) Except as otherwise provided herein, in the event of any dispute between the Parties as to any matter covered by this Agreement, the
dispute shall be governed exclusively by the procedures set forth in Section 8.01(b). 
 (b) With respect to any dispute governed by
this Section 8.01(b), the Parties shall appoint a nationally recognized independent public accounting firm (the “Accounting Firm”) to resolve such dispute. In this regard, the Accounting Firm shall make determinations with
respect to the disputed items based solely on representations made by Timken and TimkenSteel and their respective representatives, and not by independent review, and shall function only as an expert and not as an arbitrator and shall be required to
make a determination in favor of one Party only. The Parties shall require the Accounting Firm to resolve all disputes no later than 45 days after the submission of such dispute to the Accounting Firm, but in no event later than the Due Date for the
payment of Taxes or the filing of the applicable Tax Return, if applicable, and agree that all decisions by the Accounting Firm with respect thereto shall be final and conclusive and binding on the Parties. The Accounting Firm shall resolve all
disputes in a manner consistent with this Agreement and, to the extent not inconsistent with this Agreement, in a manner consistent with the historical practices of Timken and its Subsidiaries, except as otherwise required by applicable Law. The
Parties shall require the Accounting Firm to render all determinations in writing and to set forth, in reasonable detail, the basis for such determination. The fees and expenses of the Accounting Firm shall be paid by the non-prevailing Party. 

Section 8.02 Tax Sharing Agreements. All Tax sharing, indemnification and similar agreements, written or unwritten, as between Timken, on
the one hand, and TimkenSteel or a TimkenSteel Entity, on the other (other than this Agreement), shall be or shall have been terminated no later than the effective time of the Distribution and, after the effective time of the Distribution, none of
Timken, TimkenSteel or a TimkenSteel Entity shall have any further rights or obligations under any such Tax sharing, indemnification or similar agreement. 

Section 8.03 Interest on Late Payments. With respect to any payment between the Parties pursuant to this Agreement not made by the due
date set forth in this Agreement for such payment, the outstanding amount will accrue interest at a rate equal to the rate of interest from time to time announced publicly by The Wall Street Journal as its prime rate, calculated on the basis of a
year of 365 days and the number of days elapsed. 

  
 23 








 Section 8.04 Survival of Covenants. Except as otherwise contemplated by this Agreement, all
covenants and agreements of the Parties contained in this Agreement shall survive the Distribution Date and remain in full force and effect in accordance with their applicable terms, provided, however, that the representations and warranties and all
indemnification for Taxes shall survive until 90 days following the expiration of the applicable statute of limitations (taking into account all extensions thereof), if any, of the Tax that gave rise to the indemnification, provided, further, that,
in the event that notice for indemnification has been given within the applicable survival period, such indemnification shall survive until such time as such claim is finally resolved. 

Section 8.05 Termination. Notwithstanding any provision to the contrary, this Agreement may be terminated by the board of directors of
Timken, in its sole and absolute discretion, at any time prior to the Distribution. In the event of any termination of this Agreement prior to the Distribution, neither Party (nor any member of its Group or any of its respective directors or
officers) will have any liability or further obligation to the other Party (or member of its Group) with respect to this Agreement. After the Distribution Date, this Agreement may not be terminated except by an agreement in writing signed by each of
the Parties. 
 Section 8.06 Severability. Whenever possible, each provision or portion of any provision of this Agreement will be
interpreted in such manner as to be effective and valid under applicable Law, but if any provision or portion of any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable Law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or portion of any provision in such jurisdiction, and this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid,
illegal or unenforceable provision or portion of any provision had never been contained in this Agreement. 
 Section 8.07 Entire
Agreement. Except as otherwise expressly provided in this Agreement, this Agreement and any annexes, exhibits, schedules and appendices hereto constitute the entire agreement, and supersede all prior written agreements, arrangements, communications
and understandings and all prior and contemporaneous oral agreements, arrangements, communications and understandings between the Parties with respect to the subject matter of this Agreement. This Agreement will not be deemed to contain or imply any
restriction, covenant, representation, warranty, agreement or undertaking of any Party with respect to the transactions contemplated hereby other than those expressly set forth in this Agreement or in any document required to be delivered hereunder.
Notwithstanding any oral agreement or course of action of the Parties or their representatives to the contrary, no Party to this Agreement will be under any legal obligation to enter into or complete the transactions contemplated hereby unless and
until this Agreement and the Separation Agreement, as applicable, will have been executed and delivered by each of the Parties. Except as specifically set forth in the Separation Agreement and the Employee Matters Agreement, and except as provided
in Section 8.15, all matters related to Taxes or Tax Returns of the Parties and their respective Subsidiaries shall be governed exclusively by this Agreement. Except as provided in Section 8.15, in the event of a conflict between this
Agreement and the Separation Agreement or the Employee Matters Agreement with respect to such matters, this Agreement shall govern and control. 

  
 24 








 Section 8.08 Assignment. Except as expressly provided in this Agreement, neither this
Agreement nor any of the rights, interests or obligations hereunder may be assigned or delegated, in whole or in part, by operation of law or otherwise, by any Party without the prior written consent of the other Party, and any such assignment or
delegation without such prior written consent will be null and void. If any Party to this Agreement (or any of its successors or permitted assigns) (a) will consolidate with or merge into any other Person and will not be the continuing or
surviving corporation or entity of such consolidation or merger or (b) will transfer all or substantially all of its properties and/or assets to any Person, then, and in each such case, the Party (or its successors or permitted assigns, as
applicable) will ensure that such Person assumes all of the obligations of such Party (or its successors or permitted assigns, as applicable) under this Agreement, in which case the consent described in the previous sentence will not be required.

 Section 8.09 No Third-Party Beneficiaries. Except as provided in Article 3 with respect to the TimkenSteel Group and the Timken
Group, nothing in this Agreement, express or implied, is intended to or will confer upon any Person other than the Parties and their respective Subsidiaries and their respective successors and permitted assigns and nothing in this Agreement, express
