Calculation Agent in its sole discretion: 
  

	 	(A)	 The occurrence or existence of a material suspension of or limitation imposed on trading by the Relevant Exchange or otherwise relating to the
shares (or other applicable securities) of the Fund or any Successor Fund (as defined below) on the Relevant Exchange at any time during the one-hour period that ends at the Close of Trading on such day, whether by reason of movements in price
exceeding limits permitted by such Relevant Exchange or otherwise. 

  

	 	(B)	 The occurrence or existence of a material suspension of or limitation imposed on trading by any Related Exchange or otherwise in futures or options
contracts relating to the shares (or other applicable securities) of the Fund or any Successor Fund on any Related Exchange at any time during the one-hour period that ends at the Close of Trading on that day, whether by reason of movements in price
exceeding limits permitted by the Related Exchange or otherwise. 

  

	 	(C)	 The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in
general to effect transactions in, or obtain market values for, shares (or other applicable securities) of the Fund or any Successor Fund on the Relevant Exchange at any time during the one-hour period that ends at the Close of Trading on that day.

  

	 	(D)	 The occurrence or existence of any event, other than an early closure, that materially disrupts or impairs the ability of market participants in
general to effect transactions in, or obtain market values for, futures or options contracts relating to shares (or other applicable securities) of the Fund or any Successor Fund on any Related Exchange at any time during the one-hour period that
ends at the Close of Trading on that day. 

  

	 	(E)	 The closure of the Relevant Exchange or any Related Exchange with respect to the Fund or any Successor Fund prior to its Scheduled Closing Time
unless the earlier closing time is announced by the Relevant Exchange or Related Exchange, as applicable, at least one hour prior to the earlier of (1) the actual closing time for the regular trading session on such Relevant Exchange or Related
Exchange, as applicable, and (2) the submission deadline for orders to be entered into the Relevant Exchange or Related Exchange, as applicable, system for execution at the Close of Trading on that day. 

 

	 	(F)	 The Relevant Exchange or any Related Exchange with respect to the Fund or any Successor Fund fails to open for trading during its regular trading
session. 

 For purposes of determining whether a Market Disruption Event has occurred: 

 

	 	(1)	 “Close of Trading” means the Scheduled Closing Time of the Relevant Exchange with respect to the Fund or any Successor Fund; and

  
 4 

	 	(2)	 the “Scheduled Closing Time” of the Relevant Exchange or any Related Exchange on any Trading Day for the Fund or any Successor
Fund means the scheduled weekday closing time of such Relevant Exchange or Related Exchange on such Trading Day, without regard to after hours or any other trading outside the regular trading session hours. 

Anti-dilution Adjustments Relating to the Fund; Alternate Calculation 

Anti-dilution Adjustments 

The Calculation Agent will adjust the Adjustment Factor with respect to the Fund as specified below if any of the events
specified below occurs with respect to the Fund and the effective date or ex-dividend date, as applicable, for such event is after the Pricing Date and on or prior to the Calculation Day. 

The adjustments specified below do not cover all events that could affect the Fund. The Calculation Agent may, in its sole
discretion, make additional adjustments to any terms of this Security upon the occurrence of other events that affect or could potentially affect the market price of, or shareholder rights in, the Fund, with a view to offsetting, to the extent
practical, any such change, and preserving the relative investment risks of this Security. In addition, the Calculation Agent may, in its sole discretion, make adjustments or a series of adjustments that differ from those described herein if the
Calculation Agent determines that such adjustments do not properly reflect the economic consequences of the events specified herein or would not preserve the relative investment risks of this Security. All determinations made by the Calculation
Agent in making any adjustments to the terms of this Security, including adjustments that are in addition to, or that differ from, those described herein, will be made in good faith and a commercially reasonable manner, with the aim of ensuring an
equitable result. In determining whether to make any adjustment to the terms of this Security, the Calculation Agent may consider any adjustment made by the Options Clearing Corporation or any other equity derivatives clearing organization on
options contracts on the Fund. 
 For any event described below, the Calculation Agent will not be required to adjust the
Adjustment Factor unless the adjustment would result in a change to the Adjustment Factor then in effect of at least 0.10%. The Adjustment Factor resulting from any adjustment will be rounded up or down, as appropriate, to the nearest one-hundred
thousandth. 
  

	 	(A)	 Stock Splits and Reverse Stock Splits 

If a stock split or reverse stock split has occurred, then once such split has become effective, the Adjustment Factor will
be adjusted to equal the product of the prior Adjustment Factor and the number of securities which a holder of one share (or other applicable security) of the Fund before the effective date of such stock split or reverse stock split would have owned
or been entitled to receive immediately following the applicable effective date. 

  
 5 

	 	(B)	 Stock Dividends 

If a dividend or distribution of shares (or other applicable securities) to which this Security is linked has been made by
the Fund ratably to all holders of record of such shares (or other applicable security), then the Adjustment Factor will be adjusted on the ex-dividend date to equal the prior Adjustment Factor plus the product of the prior Adjustment Factor and the
number of shares (or other applicable security) of the Fund which a holder of one share (or other applicable security) of the Fund before the ex-dividend date would have owned or been entitled to receive immediately following that date; provided,
however, that no adjustment will be made for a distribution for which the number of securities of the Fund paid or distributed is based on a fixed cash equivalent value. 
  

	 	(C)	 Extraordinary Dividends 

If an Extraordinary Dividend (as defined below) has occurred, then the Adjustment Factor will be adjusted on the ex-dividend
date to equal the product of the prior Adjustment Factor and a fraction, the numerator of which is the Closing Price per share (or other applicable security) of the Fund on the Trading Day preceding the ex-dividend date, and the denominator of which
is the amount by which the Closing Price per share (or other applicable security) of the Fund on the Trading Day preceding the ex-dividend date exceeds the Extraordinary Dividend Amount (as defined below). 

For purposes of determining whether an Extraordinary Dividend has occurred: 

 

	 	(1)	 “Extraordinary Dividend” means any cash dividend or distribution (or portion thereof) that the Calculation Agent determines, in
its sole discretion, is extraordinary or special; and 

  

	 	(2)	 “Extraordinary Dividend Amount” with respect to an Extraordinary Dividend for the securities of the Fund will equal the amount per
share (or other applicable security) of the Fund of the applicable cash dividend or distribution that is attributable to the Extraordinary Dividend, as determined by the Calculation Agent in its sole discretion. 

A distribution on the securities of the Fund described below under the section entitled “—Reorganization
Events” below that also constitutes an Extraordinary Dividend will only cause an adjustment pursuant to that “—Reorganization Events” section. 
  

	 	(D)	 Other Distributions 

If the Fund declares or makes a distribution to all holders of the shares (or other applicable security) of the Fund of any
non-cash assets, excluding dividends or distributions described under the section entitled “—Stock Dividends” above, then the Calculation Agent may, in its sole discretion, make such adjustment (if

  
 6 

 
any) to the Adjustment Factor as it deems appropriate in the circumstances. If the Calculation Agent determines to make an adjustment pursuant to this paragraph, it will do so with a view to
offsetting, to the extent practical, any change in the economic position of a holder of this Security that results solely from the applicable event. 
  

	 	(E)	 Reorganization Events 

If the Fund, or any Successor Fund, is subject to a merger, combination, consolidation or statutory exchange of securities
with another exchange traded fund, and the Fund to which this Security is linked is not the surviving entity (a “Reorganization Event”), then, on or after the date of such event, the Calculation Agent shall, in its sole discretion,
make an adjustment to the Adjustment Factor or the method of determining the Redemption Amount or any other terms of this Security as the Calculation Agent determines appropriate to account for the economic effect on this Security of such event, and
determine the effective date of that adjustment. If the Calculation Agent determines that no adjustment that it could make will produce a commercially reasonable result, then the Calculation Agent may deem such event a Liquidation Event (as defined
below). 
 Liquidation Events 

If the Fund is de-listed, liquidated or otherwise terminated (a “Liquidation Event”), and a successor or
substitute exchange traded fund exists that the Calculation Agent determines, in its sole discretion, to be comparable to the Fund, then, upon the Calculation Agent’s notification of that determination to the Trustee and the Company, any
subsequent Fund Closing Price for the Fund will be determined by reference to the Fund Closing Price of such successor or substitute exchange traded fund (such exchange traded fund being referred to herein as a “Successor Fund”),
with such adjustments as the Calculation Agent determines are appropriate to account for the economic effect of such substitution on the holder of this Security. 

If the Fund undergoes a Liquidation Event prior to, and such Liquidation Event is continuing on, the date that any Fund
Closing Price of the Fund is to be determined and the Calculation Agent determines that no Successor Fund is available at such time, then the Calculation Agent will, in its discretion, calculate the Fund Closing Price for the Fund on such date by a
computation methodology that the Calculation Agent determines will as closely as reasonably possible replicate the Fund, provided that if the Calculation Agent determines in its discretion that it is not practicable to replicate the Fund (including
but not limited to the instance in which the sponsor of the index underlying the Fund discontinues publication of that index), then the Calculation Agent will calculate the Fund Closing Price for the Fund in accordance with the formula last used to
calculate such Fund Closing Price before such Liquidation Event, but using only those securities that were held by the Fund immediately prior to such Liquidation Event without any rebalancing or substitution of such securities following such
Liquidation Event. 
 If a Successor Fund is selected or the Calculation Agent calculates the Fund Closing Price as a
substitute for the Fund, such Successor Fund or Fund Closing Price will be used as a 

  
 7 

 
substitute for the Fund for all purposes, including for purposes of determining whether a Market Disruption Event exists. 

If any event is both a Reorganization Event and a Liquidation Event, such event will be treated as a Reorganization Event for
purposes of this Security unless the Calculation Agent makes the determination referenced in the last sentence of the section entitled “—Anti-dilution Adjustments—Reorganization Events” above. 

Alternate Calculation 

If at any time the method of calculating the Fund or a Successor Fund, or the Underlying Index, is changed in a material
respect, or if the Fund or a Successor Fund is in any other way modified so that the Fund does not, in the opinion of the Calculation Agent, fairly represent the price of the securities of the Fund or such Successor Fund had such changes or
modifications not been made, then the Calculation Agent may, at the close of business in New York City on the date that any Fund Closing Price is to be determined, make such calculations and adjustments as, in the good faith judgment of the
Calculation Agent, may be necessary in order to arrive at a Closing Price of an exchange traded fund comparable to the Fund or such Successor Fund, as the case may be, as if such changes or modifications had not been made, and calculate the Fund
Closing Price and the Redemption Amount with reference to such adjusted Closing Price of the Fund or such Successor Fund, as applicable. 

Calculation Agent 

The Calculation Agent will determine the Redemption Amount and the Ending Price. In addition, the Calculation Agent will
(i) determine if adjustments are required to the Fund Closing Price and/or the Adjustment Factor under the circumstances described in this Security, (ii) if the Fund undergoes a Liquidation Event, select a Successor Fund or, if no
Successor Fund is available, determine the Fund Closing Price of the Fund, and (iii) determine whether a Market Disruption Event or non-Trading Day has occurred. 

The Company covenants that, so long as this Security is Outstanding, there shall at all times be a Calculation Agent (which
shall be a broker-dealer, bank or other financial institution) with respect to this Security. 

All determinations made by the Calculation Agent with respect to this Security will be at the sole discretion of the
Calculation Agent and, in the absence of manifest error, will be conclusive for all purposes and binding on the Company and the Holder of this Security. All percentages and other amounts resulting from any calculation with respect to this Security
will be rounded at the Calculation Agent’s discretion. 
 Tax Considerations 

The Company agrees, and by acceptance of a beneficial ownership interest in this Security each Holder of this Security will be
deemed to have agreed (in the absence of a statutory, regulatory, administrative or judicial ruling to the contrary), for United States federal income tax purposes to treat this Security as a prepaid derivative contract that is an “open
transaction.” 

  
 8 

 Redemption and Repayment 

This Security is not subject to redemption at the option of the Company or repayment at the option of the Holder hereof prior
to June 29, 2020. This Security is not entitled to any sinking fund. 
 Acceleration 

If an Event of Default, as defined in the Indenture, with respect to this Security shall occur and be continuing, the
Redemption Amount (calculated as set forth in the next sentence) of this Security may be declared due and payable in the manner and with the effect provided in the Indenture. The amount payable to the Holder hereof upon any acceleration permitted
under the Indenture will be equal to the Redemption Amount hereof calculated as provided herein as though the date of acceleration was the Calculation Day. 
  

 

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions
shall for all purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication
hereon has been executed by the Trustee referred to on the reverse hereof by manual signature or its duly authorized agent under the Indenture referred to on the reverse hereof by manual signature, this Security shall not be entitled to any benefit
under the Indenture or be valid or obligatory for any purpose.

WELLS FARGO & COMPANY 

MEDIUM-TERM NOTE, SERIES K 

Due Nine Months or More From Date of Issue 

Principal at Risk Securities Linked to the 

iShares® MSCI Emerging Markets ETF due June 29, 2020 

This Security is one of a duly authorized issue of securities of the Company (herein called the
“Securities”), issued and to be issued in one or more series under an indenture dated as of July 21, 1999, as amended or supplemented from time to time (herein called the “Indenture”), between the Company and
Citibank, N.A., as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the
respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is
one of the series of the Securities designated as Medium-Term Notes, Series K, of the Company, which series is limited to an aggregate principal amount or face amount, as applicable, of $25,000,000,000 or the equivalent thereof in one or more
foreign or composite currencies. The amount payable on the Securities of this series may be determined by reference to the performance of one or more equity-, commodity- or currency-based indices, exchange traded funds, securities, commodities,
currencies, statistical measures of economic or financial performance, or a basket comprised of two or more of the foregoing, or any other market measure or may bear interest at a fixed rate or a floating rate. The Securities of this series may
mature at different times, be redeemable at different times or not at all, be repayable at the option of the Holder at different times or not at all and be denominated in different currencies. 

Article Sixteen of the Indenture shall not apply to this Security. 

The Securities are issuable only in registered form without coupons and will be either
(a) book-entry securities represented by one or more Global Securities recorded in the book-entry system maintained by the Depositary or (b) certificated
securities issued to and registered in the names of, the beneficial owners or their nominees. 
 The Company agrees, to the
extent permitted by law, not to voluntarily claim the benefits of any laws concerning usurious rates of interest against a Holder of this Security. 

Modification and Waivers 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights
and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the
Securities at the 

  
 11 

 
time Outstanding of all series to be affected, acting together as a class. The Indenture also contains provisions permitting the Holders of a majority in principal amount of the Securities of all
series at the time Outstanding affected by certain provisions of the Indenture, acting together as a class, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with those provisions of the Indenture. Certain
past defaults under the Indenture and their consequences may be waived under the Indenture by the Holders of a majority in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such
series. Solely for the purpose of determining whether any consent, waiver, notice or other action or Act to be taken or given by the Holders of Securities pursuant to the Indenture has been given or taken by the Holders of Outstanding Securities in
the requisite aggregate principal amount, the principal amount of this Security will be deemed to be equal to the amount set forth on the face hereof as the “Face Amount” hereof. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or
waiver is made upon this Security. 
 Defeasance

Indenture, relating to defeasance at any time of (a) the entire indebtedness on this Security and (b) certain restrictive covenants and certain Events of Default, upon compliance by the Company with certain conditions set forth therein,
shall not apply to this Security. The remaining provisions of Section 401 of the Indenture shall apply to this Security. 
 Authorized
Denominations

amount in excess thereof which is an integral multiple of $1,000. 
 Registration of Transfer 

Upon due presentment for registration of transfer of this Security at the office or agency of the Company in the City of
Minneapolis, Minnesota, a new Security or Securities of this series, with the same terms as this Security, in authorized denominations for an equal aggregate Face Amount will be issued to the transferee in exchange herefor, as provided in the
Indenture and subject to the limitations provided therein and to the limitations described below, without charge except for any tax or other governmental charge imposed in connection therewith. 

This Security is exchangeable for definitive Securities in registered form only if (x) the Depositary notifies the
Company that it is unwilling or unable to continue as Depositary for this Security or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and a successor depositary is not
appointed within 90 days after the Company receives such notice or becomes aware of such ineligibility, (y) the Company in its sole discretion determines that this Security shall be exchangeable for definitive Securities in registered form
and notifies the Trustee thereof or (z) an Event of Default with respect to the Securities represented hereby has occurred and is continuing. If this Security is exchangeable pursuant to the preceding sentence, it shall be exchangeable for
definitive Securities in registered 

  
 12 

 
form, having the same date of issuance, Stated Maturity Date and other terms and of authorized denominations aggregating a like amount. 

This Security may not be transferred except as a whole by the Depositary to a nominee of the Depositary or by a nominee of the
Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor of the Depositary or a nominee of such successor. Except as provided above, owners of beneficial interests in this Global
Security will not be entitled to receive physical delivery of Securities in definitive form and will not be considered the Holders hereof for any purpose under the Indenture.

 Exhibit 4.3 

TIMKENSTEEL CORPORATION 

VOLUNTARY INVESTMENT PENSION PLAN 

TIMKENSTEEL CORPORATION (the “Company”), and UNITED STEEL, PAPER AND FORESTRY, RUBBER, MANUFACTURING, ENERGY, ALLIED INDUSTRIAL AND
SERVICE WORKERS INTERNATIONAL UNION, on behalf of itself and Local Union No. 1123 (collectively, the “Union”), have entered into a Memorandum of Understanding dated May 16, 2014 (the “TimkenSteel MOU”), pursuant to
which this 401(k) retirement plan, known as the TimkenSteel Corporation Voluntary Investment Pension Plan (the “Plan”), has been established by the Company effective as of June 30, 2014. 

Prior to June 30, 2014, the Company was a wholly owned subsidiary of The Timken Company (“Timken”). Timken and the Union had
previously entered into a series of agreements, the most recent of which is dated March 2, 2012 (the “2012 401(k) Agreement”), under which Timken and the Union had agreed to establish the 401(k) retirement plan known as The Timken
Company Voluntary Investment Pension Plan (the “Prior Plan”). 
 On June 30, 2014, Timken distributed to its shareholders all
of the outstanding common shares, without par value, of the Company (the “Spinoff”), and as a result the Company ceased to be a subsidiary of Timken. In connection with the Spinoff, the assets and liabilities of the Prior Plan attributable
to the Transferred Participants, as defined below, are being spun off from the Prior Plan to this Plan, effective as of June 30, 2014, and such Transferred Participants will cease participation in the Prior Plan and become Participants in this
Plan. For the purposes of the Plan, “Transferred Participants” means individuals who are participants in the Prior Plan immediately prior to the Spinoff and who: (a) are employed by the Company or one of its subsidiaries as of the
close of business on June 30, 2014; or (b) terminated employment with Timken and its 

 
subsidiaries prior to the Spinoff and have been designated by Timken prior to the Spinoff as eligible to participate in the Plan. For the purposes of the Plan, “Transferred Employees”
means individuals who are Transferred Participants, and individuals who would otherwise be considered Transferred Participants under (a) or (b) of the previous sentence, except that they were not yet participants in the Prior Plan. 

This Plan is generally effective June 30, 2014. The benefits, rights and features of the Plan for any Transferred Employee whose
employment with Timken terminated prior to June 30, 2014 shall be governed by the terms and provisions of the Prior Plan as in effect on the date of such termination.

	B.	WAGE REDUCTION CONTRIBUTIONS, ROLLOVER CONTRIBUTIONS, AND COMPANY CONTRIBUTIONS 

1.        a.        At any time, in accordance with Section A
above, a Participant may elect to have his wages reduced and the subsequent reduction contributed to this Plan, in an amount equal to any whole percent of his Gross Earnings to be deducted from his wages payable for each pay period; provided,
however, that the percent reduction selected cannot result in more than a $17,000 wage reduction contribution on behalf of a Participant in a Plan Year (or, if greater, the dollar limitation in effect under Section 402(g)(1) of the Code)
(except to the extent permitted under Article II, Section E, Paragraph 2) and that the amount of the Wage Reduction Contribution will be determined after all other applicable deductions from the Participant’s wages are made. Wage Reduction
Contributions shall be deposited in a Participant’s Wage Reduction Contribution Account. 

b.        Participants who are age 50 or over may make additional “catch-up”
Wage Reduction Contributions of no more than $5,500 (or, if greater, the dollar limitation in effect under Section 414(v) of the Code) in accordance with, and subject to, the 

  
 21 

 
limitations of Section 414(v) of the Code. “Catch-up” Wage Reduction Contributions shall not be taken into account for purposes of the provisions of the Plan implementing the
required limitations of Sections 401(a)(30) and 415(c) of the Code (i.e., Article II, Section B, Paragraph 1.a. and Article II, Section C, respectively). In addition, notwithstanding any provision of the Plan to the
contrary, the Plan shall not be treated as failing to satisfy the requirements of Sections 401(k)(3), 401(k)(11), 410(b), or 416 of the Code, as applicable, by reason of the making of any such “catch-up” Wage Reduction Contributions. In
furtherance of, but without limiting the foregoing, (1) Wage Reduction Contributions for a Plan Year which exceed the statutory limit described in Article II, Section B, Paragraph 1.a. or Article II, Section C shall be treated as
“catch-up” Wage Reduction Contributions; and (2) “catch-up” Wage Reduction Contributions shall be permitted to be made on a payroll-by-payroll basis; provided, however, that a Wage Reduction Contribution may only be
characterized as a “catch-up” Wage Reduction Contribution on a Plan Year basis. Finally, except as specifically provided in the Plan, the term “Wage Reduction Contributions” when used herein shall include all “catch-up”
Wage Reduction Contributions. 
 2.        A Participant’s election as to the rate of his Wage
Reduction Contributions to this Plan will remain in effect until the Participant changes or suspends his election, ceases to be eligible to participate, or terminates his participation in this Plan. 

3.        A Participant may change his election as to the rate of Wage Reduction Contributions to this
Plan on any business day. Any change made will be effective as soon as administratively practicable as of the pay period that occurs after the Company receives sufficient notice of the change or, if later, on a future date specified by the
Participant and acceptable to the Company. Any change made will be effective for all succeeding pay periods, unless changed again by the same procedure. 

  
 22 

 4.        A Participant, after filing with the Company
the form prescribed by the Plan Administrator, may make a cash contribution to the Trust in the form of a Rollover Contribution. Before completing the Rollover Contribution, the Participant shall furnish satisfactory evidence to the Plan
Administrator that the proposed Rollover Contribution satisfies the requirements of Section 408(d)(3) of the Code. Rollover Contributions shall be deposited in a Participant’s Rollover Contribution Account. 

 

	C.	LIMITS ON CONTRIBUTIONS 

 1.         In no event
shall the annual addition to a Participant’s account under this Plan and any other contributions to qualified defined contribution plans maintained by the Company exceed the lesser of $50,000 (or, if greater, the dollar limitation indexed for
inflation under Section 415(d) of the Code) or one hundred percent (100%) of the Participant’s total compensation from the Company. The annual addition shall be equal to the sum of a Participant’s Wage Reduction Contributions,
Company Contributions, and amounts allocated after March 31, 1984, to an individual medical account, as defined in Section 415(c)(2) of the Code, which is a part of a pension or annuity plan maintained by the Company. Amounts derived from
contributions paid or accrued after December 31, 1985, in taxable years ending after such date, which are attributable to post-retirement medical benefits, allocated to the separate account of a key employee, as defined in
Section 419A(d)(3) of the Code, under a welfare benefit fund, as defined in Section 419(e) of the Code, maintained by the Company are also treated as annual additions. For purposes of this Section C, compensation shall include all amounts
received by a Participant from the Company during a Plan Year for the performance of personal services to the extent that such amounts are includable in taxable income, including any 

  
 23 

 
payments made to a Participant by the later of (a) two and one-half months after the date of the Participant’s severance from employment with the Company or (b) the end of the
limitation year that includes the date of the Participant’s severance from employment with the Company, provided that, absent a severance from employment, such payments would have been paid to the Participant while the Participant continued in
employment with the Company and are regular compensation for services performed during the Participant’s regular working hours, compensation for services outside the Participant’s regular work hours (such as overtime or shift differential
pay), commissions, bonuses or other similar compensation. In no event shall the amount of Participant Wage Reduction Contributions to a Participant’s account exceed $17,000 for any Plan Year (or, if greater, the dollar limitation in effect
under Section 402(g)(1) of the Code). 
 2.        If the annual addition limitation for any
Participant would be exceeded by the amounts contributed to this Plan and any other defined contribution plans maintained by the Company, the contributions to the Participant’s account made under this Plan shall be reduced as necessary. 

 

	D.	INTERESTS NON-FORFEITABLE 

 Participants shall have an immediate fully vested and
non-forfeitable right to Wage Reduction Contributions, Rollover Contributions and Company Contributions properly credited to their respective accounts and the income attributable thereto. 

 

	E.	VETERANS’ RIGHTS 

 1.        A Participant
who is reemployed by the Company pursuant to the provisions of the Uniformed Services Employment and Reemployment Rights Act of 1994 shall be treated as not having incurred a break in service with the Company by reason of such Participant’s
period or periods of service in the armed forces of the United States. Each period served by a 

  
 24 

 
Participant in the armed forces shall, upon reemployment, be deemed to constitute service with the Company for purposes of determining and non-forfeitability of benefits and the accrual of
benefits under the Plan. For the avoidance of doubt, any Participant who is a Transferred Employee, and who otherwise satisfies the requirements of this Article II, Section E regarding Veterans’ Rights, shall be considered to be reemployed by
the Company for the purposes of this Article II, Section E upon employment with the Company even if such Participant had previously been employed by Timken and not by the Company. 

2.         Effective December 12, 1994, a Participant so reemployed shall be entitled to Accrued
Benefits that are contingent on the making of, or derived from, Wage Reduction Contributions only to the extent such Participant makes payment to the Plan with respect to such Wage Reduction Contributions. No such payment may exceed the amount the
Participant would have been permitted to contribute had the Participant remained continuously employed by the Company through the period of service in the armed forces; provided, that, notwithstanding anything to the contrary herein, payments made
to the Plan with respect to Wage Reduction Contributions for the year(s) prior to the year in which the Participant becomes reemployed (informally known as Military Make-Up Contributions) shall not count towards the contribution limits set forth in
Article II with respect to Wage Reduction Contributions made for the year in which the payments are made. Any payment of Wage Reduction Contributions to the Plan shall be made during the period beginning with the date of reemployment and whose
duration is three (3) times the period of the Participant’s service in the armed forces, not to exceed a maximum duration of five (5) years. 

  
 25 

 3.         For purposes of computing Wage Reduction
Contributions under Section E, Paragraph 2, above, the Participant’s Gross Earnings during the period of service in the armed forces shall be computed at the rate the Participant would have received, but for the period of service in the armed
forces, or, in the case that the determination of such rate is not reasonably certain, on the basis of the Participant’s average Gross Earnings during the twelve (12)-month period immediately preceding such period of service in the armed
forces, or if shorter, the period of employment immediately preceding such period. 

4.        Notwithstanding any provision of this Plan to the contrary, if a Participant dies during his
or her period of service with the armed forces, the survivors of the Participant will be entitled to any benefits provided under the Plan that such survivors would have been entitled to receive if the Participant had become reemployed by the Company
on the day immediately prior to his or her date of death (entitling such Participant to additional benefit accruals and vesting service relating to periods of qualified military leave under Section 414(u) of the Code) and then terminated
employment on his actual date of death. 
 5.        Effective January 1, 2009, to the extent
required by Section 414(u)(12) of the Code, the term “Employee” as used under the Plan and this Agreement shall include an individual receiving differential wage payments (within the meaning of Section 414(u)(12)(D) of the Code)
from the Company. 
 6.        Effective January 1, 2009, to the extent required by
Section 414(u)(12)(B) of the Code, for purposes of eligibility to receive a distribution under Article III of this Agreement, a Participant shall be treated as having terminated employment with the Company during any period that the Participant
is performing service in the uniformed services described in Section 3401(h)(2)(A) of the Code. A Participant who receives a distribution from the Plan by reason of this Section E, Paragraph 6 shall have his Wage Reduction Contributions
suspended for a period of six (6) months beginning on the date of distribution. 

  
 26 

 ARTICLE III - OPERATION OF THE TRUST 

 

	A.	INVESTMENT OF FUNDS 

 1.         A Participant
will be able to invest his Wage Reduction Contributions, Rollover Contributions, and Company Contributions in the investment options offered under the Plan, which options shall be selected by a committee responsible for the management of investments
for the Plan (the “Investment Committee”). The Investment Committee will offer four (4) basic investment options to Participants and may select additional investment options. There will be no investment fees for Participants for the
four (4) basic options, but investment fees on the additional options will be charged to the Account of any Participant electing them. See Article IX for a description of the Timken Common Stock Fund. 

2.         At the time the Participant enrolls or re-enrolls in the Plan, he or she may elect what
percentage, if any, of his Wage Reduction Contributions and Rollover Contributions, in increments of one percent (1%), he wishes to place in each investment option. A Participant who does not make any selection of investment options will have his
Wage Reduction Contributions and Rollover Contributions placed in an investment option or options selected in a manner determined by the Investment Committee, until such time as the Participant selects investment options. 

A Participant can request fund transfers on any business day of his prior Wage Reduction Contributions, Rollover Contributions, and Company
Contributions from one investment option to another. 
 The Participant may elect what percentage, if any, of those assets in the
Participant’s investment options will be reallocated in one percent (1%) increments to the investment options chosen by the Participant. In order to effectuate a transfer into or out of the fund holding TimkenSteel Common Shares,
TimkenSteel Common Shares may be (a) bought and/or sold on 

  
 27 

 
the open market at the market price of the stock on any Valuation Date, or (b) bought from and/or sold to the Company at the average of the high and low market price on the Valuation Date
the request for purchase and/or sale is received by the Company, if cash is not available. 

3.         This Plan is intended to qualify as an ERISA Section 404(c) Plan within the meaning of
regulations issued under Section 404(c) of ERISA, with respect to all contributions under the Plan (the “Directed Contributions”). Participants shall have the opportunity, in accordance with this Article III, to give investment
instructions (with an opportunity to obtain written confirmation of such instructions) to the Plan Administrator as to the investment options. The Plan Administrator shall be obligated to comply with such instructions except as otherwise provided in
the regulations issued under Section 404(c) of ERISA. 
 The Plan Administrator will provide or will make arrangements to provide each
Participant with a description of the investment alternatives generally available under the Plan; and with respect to each designated investment alternative, a general description of the investment objectives, risk and return characteristics of each
alternative, including information relating to the type and diversification of assets comprising the investment portfolio. 
 The Plan
Administrator by separate document may prescribe the form and the manner in which such direction shall be made, as well as the frequency with which such directions may be made or changed and the dates as of which they shall be effective, in a manner
consistent with the foregoing. The Plan Administrator shall be the fiduciary identified to furnish the information as contemplated by Section 404(c) of ERISA, but may designate on its behalf another person or entity to provide such information
or to perform any of the obligations of the Plan Administrator under this paragraph. 

  
 28 

 None of the Trustee, Plan Administrator, the Company nor any fiduciary of the Plan shall be
liable to the Participant or any of his Beneficiaries for any loss resulting from action taken at the direction of the Participant. All fiduciaries of the Plan shall be relieved of any fiduciary liability with respect to the Participant directing
his investments pursuant to Section 404(c) of ERISA. 
 4.         Each business day, the
Trustee or its designee shall, by appropriate accounting procedures, determine the Beneficial Interest of each Participant in the assets then held in the Trust. 

5.         As soon as administratively possible following the end of each calendar quarter, each
Participant shall receive a statement showing the details of the Participant’s Beneficial Interest in the Trust. 

6.         The Trustee shall, following the end of each Valuation Date, value all assets of the Trust,
allocate net gains or losses, and process additions to and withdrawals from Account balances in the following manner: 
  

	 	a.	The Trustee shall first compute the fair market value of securities and/or the other assets comprising each investment option offered under the Plan for direction of investment by Participants. Each Account balance
shall be adjusted each business day by applying the closing market price of the investment option on the current business day to the share/unit balance of the investment option as of the close of business on the current business day.

  
 29 

	 	b.	The Trustee shall then account for any requests for additions or withdrawals made to or from the specific designated investment option by any Participant, including allocations of contributions. In completing the
valuation procedure described above, such adjustments in the amounts credited to such Accounts shall be made on the business day to which the investment activity relates. Contributions received by the Trustee pursuant to this Plan shall not be taken
into account until the Valuation Date coinciding with or next following the date such contribution was both actually paid to the Trustee and allocated among the Accounts of Participants. 

 

	 	c.	Notwithstanding Subsections a. and b. above, in the event a Pooled Investment Account is created as an investment option in this Plan, valuation of the Pooled Investment Account and allocation of earnings of the Pooled
Investment Account shall be governed by the administrative services agreement for such Pooled Investment Account. The provisions of any such administrative services agreement shall be incorporated by reference and made a part of this Plan.

 It is intended that this Section operate to distribute among the Participant’s Accounts in the Trust, all income of
the Trust and changes in the value of the assets of the Trust. 
 7.         The Plan Administrator
shall provide notice of any Blackout Period (as defined in Article III, Section A, Paragraph 8) to all Participants and Beneficiaries whose rights under the Plan will be temporarily suspended, limited, or restricted by the Blackout Period and to the
issuer of TimkenSteel Common Shares subject to such Blackout Period. The notice required shall be written in a manner calculated to be understood by the average Plan Participant and shall include the following information: 

  
 30 

	 	a.	the reasons for the Blackout Period; 

  

	 	b.	a description of the rights otherwise available to Participants and Beneficiaries under the Plan which will be temporarily suspended, limited, or restricted by the Blackout Period; 

 

	 	c.	the expected beginning date and ending date of the Blackout Period; 

  

	 	d.	in the case of investments affected, a statement that the Participant or Beneficiary should evaluate the appropriateness of their current investment decisions in light of their inability to direct or diversify assets in
their Accounts during the Blackout Period; 

  

	 	e.	in any case in which the notice required is not furnished at least 30 days in advance of the last date on which Participants and Beneficiaries could exercise the affected rights immediately before the commencement of
the Blackout Period, a statement that federal law generally requires that such notice be furnished at least 30 days in advance of the last date on which Participants and Beneficiaries could exercise the affected rights immediately before the
commencement of a Blackout Period, and an explanation why at least 30 days advance notice could not be furnished; and 

  

	 	f.	the name, address, and telephone number of the Plan Administrator responsible for answering questions about the Blackout Period. 

If following the issuance of the notice there is a change in the beginning or ending date of the Blackout Period, the Plan Administrator shall furnish all
affected Participants and Beneficiaries and the issuer of TimkenSteel Common Shares an updated notice explaining the reasons for the change in the date and identifying all material changes in the information contained in the prior notice. 

  
 31 

 8.         The term “Blackout Period” means, in
connection with this Plan, any period for which any ability of Participants or Beneficiaries under the Plan, which is otherwise available under the terms of such Plan, to direct or diversify assets credited to their Accounts, to obtain loans from
the Plan, or to obtain distributions from the Plan, is temporarily suspended, limited, or restricted, if such suspension, limitation, or restriction is for any period of more than three consecutive business days. A “Blackout Period” does
not include a suspension, limitation, or restriction: 
  

	 	a.	which occurs by reason of the application of the federal securities laws; 

  

	 	b.	which is a change to the Plan which provides for a regularly scheduled suspension, limitation, or restriction which is disclosed to all affected Participants or Beneficiaries through any summary of material
modification, any materials describing specific investment alternatives under the Plan, or any changes thereto; or 

  

	 	c.	which applies only to one or more individuals, each of whom is a Participant, an Alternate Payee, or any other Beneficiary pursuant to a qualified domestic relations order. 

9.         Any Participant who is not in the possession of material, nonpublic information wishing to
engage in a transaction involving more than $10,000 of TimkenSteel Common Shares within a six (6) month period shall first obtain approval from the Company’s Law Department for such transaction. Approval need not be sought for any
transaction that does not itself, or together with other transactions by the Participant in TimkenSteel Common Shares during the preceding six month period, exceed $10,000. 

  
 32 

	B.	DISTRIBUTIONS AND HARDSHIP WITHDRAWALS FROM THE TRUST 

  

			
		
	 1.
	  	 a.        The shares held in the Trust for the benefit of a
Participant shall be distributed to the Participant at the Participant’s request upon retirement at or after Normal Retirement Age, upon early retirement as provided under the then current Pension Agreement, upon reaching April 1 of the
calendar year following the calendar year in which the Participant attains age seventy and one-half (70-1/2), upon a break in Continuous Service with the Company, to the Participant’s Beneficiary upon the death of the Participant, or as a
hardship withdrawal, except as hereinafter provided.
  

b.       Early retirement shall include retirement at any age under sixty-five
(65) years with not less than thirty (30) years of Continuous Service, retirement at the age of sixty (60) years with not less than twenty-five (25) years of Continuous Service, retirement at the age of sixty-two (62) years
with not less than fifteen (15) years of Continuous Service, retirement with an actuarially reduced Pension Benefit between the ages of sixty (60) and sixty-two (62) with not less than fifteen (15) years of Continuous Service,
retirement due to shutdown or layoff, and retirement due to disability.
  

c.        Following a Participant’s attainment of his Normal Retirement
Age, the Company shall give him notice in accordance with applicable law that Plan payments are being suspended during any month after his Normal Retirement Age and before he retires during which he completes 40 or more Hours of Service (within the
meaning of clause (1) of Article I, Section 2(b)). A Participant shall be entitled to receive Plan benefits after his Normal Retirement Age and before he retires during any month in which he completes fewer than 40 such Hours of
Service.

  
 33 

	    	2. 	a.	 The shares and cash held in the Trust for the benefit of a Participant remaining undistributed at the time of the Participant’s death
shall be distributed to the Participant’s Beneficiary. Except as provided in Paragraph 2.b. below, (1) the sole Beneficiary of a Participant who is married to or joined in a civil union with a Spouse at the time of his death shall be his
Spouse, and (2) the sole Beneficiary of a Participant who is not married to or joined in a civil union with a Spouse at the time of his death shall be his estate. 

 

	 	b.	A Participant may designate one or more beneficiaries other than or in addition to his Spouse or estate, but only in accordance with the following rules: 

 

	 	(1)	A Beneficiary designation may be made, revoked or changed only in writing on a form supplied by the Plan Administrator, signed by the Participant and filed with the Plan Administrator prior to the Participant’s
death. If a valid Beneficiary designation is revoked and not replaced with a new and valid Beneficiary designation prior to the Participant’s death, the Beneficiary shall be as provided in Paragraph 2.a. above. An effective Beneficiary
designation filed with the Plan Administrator by a Participant shall act to revoke in their entirety all previous benefits designations filed by such Participant. 

  
 34 

	 	(2)	A Beneficiary must be a natural person, a trust that meets the requirements provided in Paragraph b.(3) below, the Participant’s estate, or an entity that is a tax-exempt organization qualified under
Section 501(c)(3) of the Code. The person, trust or other entity to be designated as a Beneficiary, other than the Participant’s estate, must be in existence at the time the Beneficiary designation is filed with the Plan Administrator. The
Plan Administrator may require the Participant to provide evidence of the existence of the designated Beneficiary and, if applicable, the tax-exempt status of the Section 501(c)(3) organization, or the identity of named executor(s) of the
Participant’s estate. 

  

	 	(3)	To be designated as a Beneficiary, a trust must meet the following requirements: (a) the trust must be a valid trust under state law (or would be except for the fact that there is no trust corpus); and (b) the
beneficiaries of the trust are identifiable from the trust instrument. The Plan Administrator may require the Participant to submit either the entire trust instrument or a certification of the trust on a form provided by the Plan Administrator.

  

	 	c.	 A Participant may elect at any time to waive the surviving Spouse as Beneficiary and may make any such election at any time. Such an election shall
not take effect with respect to a DOMA Spouse unless the DOMA 

  
 35 

	 	
Spouse of the Participant (as of the date of death ) has consented in writing to such election, such election designates a Beneficiary which may not be changed without the consent of the DOMA
Spouse (or the consent of the DOMA Spouse expressly permits designations by the Participant without any requirement of further consent by the DOMA Spouse) and the DOMA Spouse’s consent acknowledges the effect of such election and is witnessed
by a notary public, or it is established to the satisfaction of the Plan Administrator that the consent required may not be obtained because there is no DOMA Spouse, because the DOMA Spouse cannot be located, or because of such other circumstances
as the Secretary of the Treasury, may by regulations, prescribe. Any consent by a DOMA Spouse (or establishment that the consent of a DOMA Spouse may not be obtained) shall be effective only with respect to such DOMA Spouse. 

3.         All investment options, including TimkenSteel Common Shares, shall be valued using the
market value of such investments and the closing price of TimkenSteel Common Shares on the day preceding the distribution, but not to exceed seven (7) business days from the date forms are received by the Trustee. 

 

			
		
	 4.         a.
	    	Distributions shall be made in cash in a lump sum or in installments as soon as possible following completion of a distribution request form following one of the events described in Article III, Section B, Paragraph 1, above,
provided, however, that a Participant may elect to receive any TimkenSteel Common Shares in his Account as a distribution in kind. Notwithstanding the foregoing, unless the Participant otherwise elects,

  
 36 

	 	
distribution to a Participant will be made no later than the sixtieth (60th) day after the close of the Plan Year in which Continuous Service is broken, except as the minimum distribution
requirements set forth in Article III, Section B, Paragraph 6, below, may otherwise require, or if the value of the Participant’s Account is less than $1,000. No distribution can be made from the Plan, after the Benefit Starting Date, without
the written consent of the Participant, except that the Plan will make an immediate lump-sum distribution to a Participant, if the value of the Participant’s Account is not more than $1,000. 

 

	 	b.	If the value of a Participant’s Account balance exceeds $1,000 and the Account balance is immediately distributable, the Participant (or where the Participant has died, the Beneficiary) must consent to any
distribution of such Account balance. An Account balance is immediately distributable if any part of the Account balance could be distributed to the Participant or the surviving Spouse before the Participant attains, or would have attained if not
deceased, the later of Normal Retirement Age or age 62. The value of a distribution will be calculated to include any Rollover Contributions and any earnings allocated to Rollover Contributions. 

 

	 	c.	 A Participant electing to receive a distribution in installments shall elect the frequency of the distribution which may be monthly, quarterly,
semi-annually, or annually over a period not to exceed the recipient’s life expectancy according to procedures established by the Company. A Participant must have a minimum Account balance of $1,000 to elect the

  
 37 

	 	
installment distribution. After installment payments begin, when the Account balance becomes $1,000 or less, the entire balance will be distributed in a lump-sum payment. Following the
Participant’s death, the remainder of the Account balance, if any, shall be distributed to the Participant’s Beneficiary in a lump sum payment regardless of the amount. 

 

	 	d.	Unless the Participant otherwise elects, the payment of benefits to a Participant shall begin no later than the 60th day after the latest of the close of the year in which (a) the Participant attains age sixty-five
(65), (b) the Participant completes ten (10) years of Continuous Service, or (c) the Participant terminates his service with the Company. The election to postpone the payment of benefits beyond the time specified above shall be made
by submitting to the Plan Administrator a written statement, signed by the Participant, which describes the benefit and the date on which the payment of such benefit shall commence. Such an election may not be made if the exercise of such election
will cause benefits payable under this Agreement in the event of the death of the Participant to be more than incidental. 

  

			
		
	 5.        a.
	  	For distributions made from the Plan, the appropriate tax withholdings will be made, unless the Participant instructs the Plan Administrator, pursuant to procedures to be implemented by the Plan Administrator, to roll over directly
his eligible rollover distribution to an eligible retirement plan. A direct rollover is a payment by the Plan to the eligible retirement plan specified by the Participant. An eligible rollover distribution is any

  
 38 

	 	
distribution of all or any portion of the balance to the credit of the Participant, except that an eligible rollover distribution does not include (1) any distribution that is one of a
series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the Participant or the joint lives (or joint life expectancies) of the Participant and the Participant’s designated
Beneficiary, or for a specified period of ten (10) years or more and (2) any distribution to the extent such distribution is required under Section 401(a)(9) of the Code. An eligible retirement plan is an individual retirement account
described in Section 408(a) of the Code, an individual retirement annuity described in Section 408(b) of the Code, an annuity plan described in Section 403(a) of the Code, an annuity contract described in Section 403(b) of the
Code, an eligible deferred compensation plan described in Section 457(b) of the Code which is maintained by an eligible employer described in Section 457(e)(1)(A) of the Code, or a qualified trust described in Section 401(a) of the
Code, that accepts the Participant’s eligible rollover distribution. If any portion of an eligible rollover distribution is attributable to payments or distributions from a designated Roth account defined in Section 402 of the Code, an
eligible retirement plan with respect to such portion shall include only another designated Roth account and a Roth IRA. For purposes of this provision, a Participant includes an Employee or former Employee, a Participant’s surviving DOMA
Spouse, a Participant’s DOMA Spouse or former DOMA Spouse who is the Alternate Payee 

  
 39 

	 	under a qualified domestic relations order, as defined in Section 414(p) of the Code, and a Participant’s Beneficiary who is not a DOMA Spouse (provided such beneficiary is a designated beneficiary within the
meaning of Section 401(a)(9) of the Code); provided, however, that in the case of a Participant’s Beneficiary who is not a DOMA Spouse, an eligible retirement plan means only an individual retirement account described in
Section 408(a) of the Code and an individual retirement annuity described in Section 408(b) of the Code. 

  

	 	b.	All components of a hardship withdrawal are not an eligible rollover contribution. 

 6.
        Required Distributions. 
  

	 	a.	General Rules. 

  

	 	(i)	The requirements of this Article III, Section B, Paragraph 6, shall apply to any distribution of a Participant’s Account and shall take precedence over any inconsistent provisions of this Plan, provided that the
requirements of this Article III, Section B, Paragraph 6, shall not enlarge the distribution options currently available to Participants and Beneficiaries under the other provisions of Article III, Section B, of the Plan. 

 

	 	(ii)	 All distributions required under this Section shall be determined and made in accordance with the regulations under Section 401(a)(9) of the
Code, including the minimum distribution incidental benefit requirement of Section 1.401(a)(9)-2 of the regulations. 

  
 40 

	 	(iii)	Except as otherwise provided in Article III, Section B, Paragraph 6.m, the Plan will apply the minimum distribution requirements of Section 401(a)(9) of the Code in accordance with the regulations under
Section 401(a)(9) promulgated on April 17, 2002, notwithstanding any provisions of the Plan to the contrary. 

  

	 	b.	Distributions Commencing During a Participant’s Lifetime. 

  

	 	(i)	The entire interest of a Participant must be distributed to such Participant no later than the Participant’s Required Beginning Date, or must be distributed, beginning not later than the Required Beginning Date,
over the life of the Participant or joint lives of the Participant and designated Beneficiary or over a period not extending, beyond the life expectancy of the Participant or the joint life and last survivor expectancy of the Participant and the
designated Beneficiary. 

  

	 	(ii)	Required Beginning Date means, for a Participant who is a 5-percent owner (as defined in Section 416 of the Code), April 1 of the calendar year following the calendar year in which he attains age 70 1/2. 

  

	 	(iii)	 Required Beginning Date means, for any Participant who is not a 5-percent owner (as defined in Section 416 of the Code), April 1 of the
calendar year following the later of the calendar year in which 

  
 41 

	 	
he attains age 70 1/2 or the calendar year in which he retires. Any such Participant
attaining age 701/2 who is still employed by the Company may elect to defer distribution until the calendar year following the calendar year
in which he retires. 

  

	 	(iv)	The applicable distribution period for required minimum distributions for distribution calendar years up to and including the distribution calendar year that includes the Participant’s death is determined using the
Internal Revenue Service’s Uniform Lifetime Table for the Participant’s age as of the Participant’s birthday in the relevant distribution calendar year. 

 

	 	c.    	Distributions Before Required Beginning Date. Lifetime distributions made before the Participant’s Required Beginning Date for calendar years before the Participant’s first distribution calendar year,
need not be made in accordance with this Article III, Section B, Paragraph 6. However, if distributions commence before the Participant’s Required Beginning Date under a particular distribution option, the distribution option fails to satisfy
the provisions of Section 401(a)(9) of the Code at the time distributions commence, if under the terms of the particular distribution option, distributions to be made for the Participant’s first distribution calendar year or any subsequent
distribution calendar year fail to satisfy Section 401(a)(9) of the Code. 

  
 42 

	 	d.    	Death After Distributions Have Begun. If distribution of the Participant’s interest has begun and the Participant dies before his entire interest has been distributed to him, the remaining portion of such
interest will continue to be distributed at least as rapidly as under the method of distribution being used prior to the Participant’s death. The applicable distribution period for distribution calendar years after the distribution calendar
year containing the Participant’s death is either the longer of the remaining life expectancy of the Participant’s designated Beneficiary or the remaining life expectancy of the Participant. If the Beneficiary is not an individual or does
not otherwise meet the requirements of Section 401(a)(9) of the Code, the remaining life expectancy of the Participant must be utilized. 

  

	 	e.    	Death Before Required Beginning Date. If the Participant dies before his Required Beginning Date and distribution of his interest, distribution of the Participant’s entire interest shall be completed by
December 31 of the calendar year containing the fifth anniversary of the Participant’s death. 

  

	 	f.    	Minimum Distribution Amount. 

  

	 	    	If a Participant’s benefit is to be distributed over: 

  

	 	(i)	a period not extending beyond the life expectancy of the Participant or the joint life and last survivor expectancy of the Participant and the Participant’s designated Beneficiary, or 

 

	 	(ii)	 a period not extending beyond the life expectancy of the designated Beneficiary, the amount required to be distributed for each calendar year
beginning with the distributions for the first distribution calendar year, must be at least equal to the quotient 

  
 43 

	 	
obtained by dividing the Participant’s benefit by the applicable distribution period. For distribution calendar years up to and including the distribution calendar year that includes the
Participant’s death, the required minimum distribution amount is determined under the Uniform Lifetime Tables promulgated by the Internal Revenue Service for the Participant’s age as of his birthday in the relevant distribution calendar
year. If a Participant dies on or after the Required Beginning Date, the distribution period available for calculating the amount that must be distributed during the distribution calendar year that includes the Participant’s death is determined
as if the Participant had lived throughout the year. If the sole designated Beneficiary of a Participant is the Participant’s surviving DOMA Spouse, for required minimum distributions during the Participant’s lifetime, the applicable
distribution period is the longer of the distribution period determined in accordance with the preceding three sentences or the joint life expectancy of the Participant and DOMA Spouse using the Participant’s and DOMA Spouse’s attained
ages as of the Participant’s and DOMA Spouse’s birthdays in the distribution calendar year. The DOMA Spouse is the sole designated Beneficiary for purposes of determining the applicable distribution period only if the DOMA Spouse is the
sole Beneficiary of the Participant’s entire interest at all times during the distribution calendar year. 

  
 44 

	 	g.	Life expectancies for purposes of determining required minimum distributions must be computed using the Single Life Table and the Joint and Last Survivor Table promulgated by the Internal Revenue Service.

  

	 	h.	If distributions are made in accordance with this Article III, Section B, Paragraph 6, the minimum distribution incidental benefit requirement is satisfied. 

 

	 	i.    	Timing of Distributions. The minimum distribution required for the Participant’s first distribution calendar year must be made on or before the Participant’s Required Beginning Date. The minimum
distribution for other calendar years, including the minimum distribution for the distribution calendar year in which the Participant’s Required Beginning Date occurs, must be made on or before December 31 of that calendar year.

  

	 	j.    	Distribution to a Charitable Organization. If a Participant selects as his Beneficiary a tax-exempt organization qualified under Section 501(c)(3) of the Code, any interest under the Plan payable to said
tax-exempt organization must be distributed no later than September 30 of the calendar year following calendar year in which the Participant dies. 

  

	 	k.    	Multiple Plans. If a Participant is a participant in more than one qualified retirement plan, the plans in which the Participant participates are not permitted to be aggregated for purposes of testing whether the
distribution requirements are met. The distribution of the benefit of the Participant under each plan must separately meet the requirements. 

  
 45 

	 	l.	Special Accounts. For purposes of this Plan, the ESOP Account and the Non-ESOP Account for each Participant will be aggregated for purposes of satisfying the minimum distribution rules, unless there are different
Beneficiaries for such Accounts, in which case the distribution rules will separately apply. 

  

	 	m.    	2009 Required Minimum Distributions. 

  

	 	(i)    	2009 RMDs. Notwithstanding the preceding provisions of this Article III, Section B, Paragraph 6, a Participant or Beneficiary who would have been required to receive required minimum distributions for
2009 but for the enactment of Section 401(a)(9)(H) of the Code (“2009 RMDs”), and who would have satisfied that requirement by receiving distributions that are equal to the 2009 RMDs, will not receive those distributions for 2009
unless the Participant or Beneficiary chooses to receive such distributions. Participants and Beneficiaries described in the preceding sentence will be given the opportunity to elect to receive the distributions described in the preceding sentence.
In addition, notwithstanding Article III, Section B, Paragraph 5 of the Plan, and solely for purposes of applying the direct rollover provisions of the Plan, 2009 RMDs will be treated as eligible rollover distributions on or after June 8, 2009.
Prior to June 8, 2009, a direct rollover was offered only for distributions that would be eligible rollover distributions without regard to Section 401(a)(9)(H) of the Code. 

  
 46 

	 	(ii)    	Extended 2009 RMDs. Notwithstanding the preceding provisions of this Article III, Section B, Paragraph 6, a Participant or Beneficiary who would have been required to receive 2009 RMDs but for the
enactment of Section 401(a)(9)(H) of the Code, and who would have satisfied that requirement by receiving distributions that are one or more payments in a series of substantially equal distributions (that include the 2009 RMDs) made at least
annually and expected to last for the life (or life expectancy) of the Participant, the joint lives (or joint life expectancy) of the Participant and the Participant’s designated Beneficiary, or for a period of at least 10 years (“Extended
2009 RMDs”), will receive those distributions for 2009 unless the Participant or Beneficiary chooses not to receive such distributions. For purposes of applying the direct rollover provisions of Article III, Section B, Paragraph 5 of the Plan,
Extended 2009 RMDs are not treated as eligible rollover distributions. 

  

	 	(iii)    	 Rollover Contributions. Subject to the timing requirements outlined in applicable rules and regulations, a Participant may contribute to the
Trust as a Rollover Contribution any 2009 RMDs and Extended 2009 RMDs distributed from the Plan to the Participant. 

  
 47 

 7.         A Participant or Beneficiary otherwise
entitled to a distribution from the Plan may elect to retain said distribution in the Plan until such time as the Participant or Beneficiary shall direct the Company to make said distribution, provided that such distribution must be made not later
than the time specified in Article III, Section B, Paragraphs 5 and 6 above. Upon written notice (or by any other method approved by the Company) from the Participant or Beneficiary, such distribution shall be made in cash in a lump sum or in
installments as soon as possible after the notice is received, provided, however, that a Participant may elect to receive any TimkenSteel Common Shares in his Account as a distribution in kind. During the time such distribution remains in the Plan,
the Participant may make the investment transfers described in Article III, Section A, Paragraph 2 above. 

8.         The assets of the Trust to be distributed to a Participant or Beneficiary shall include
dividends attributable to investment in TimkenSteel Common Shares and Timken Common Shares which are payable to shareholders of record as of the end of the quarter with respect to which the calculation is being made. 

 

	    	9. 	a.	 Partial or total distributions of his Wage Reduction Contribution Account, Rollover Contribution Account and/or Company Contribution Account
may also be made to a Participant, upon application to the Company, in cases of hardship. The distribution will be drawn pro-rata from all the available investment funds. Any TimkenSteel Common Shares or Timken Common Shares held in any of these
Accounts which will comprise part of the distribution shall be liquidated by the Trustee prior to the 

  
 48 

	 	
distribution to the Participant. If a Participant elects a withdrawal prior to the date he retires, becomes disabled, or terminates his service with the Company, such withdrawal will require the
consent of the Plan Administrator and such consent shall be given only if the Plan Administrator determines that the purpose of the withdrawal is to meet immediate and heavy financial needs of the Participant, the amount of the withdrawal does not
exceed such financial need, and the amount of the withdrawal is not reasonably available from the resources of the Participant. 

  

	 	b.	 The determination of whether a Participant has an immediate and heavy financial need will be made on the basis of all relevant facts and
circumstances. Financial needs which will be deemed immediate and heavy financial need are the purchase of a primary residence (excluding mortgage payments) of the Participant, payment of post-secondary educational tuition for a year for the
Participant, the Participant’s DOMA Spouse, Spouse that is a Beneficiary, children or dependents (as defined in Section 152 of the Code and, for taxable years beginning on or after January 1, 2005, without regard to Sections
152(b)(1), (b)(2), or (d)(1)(B) of the Code), health care expenses incurred by a Participant or his dependents (in the case of medical care for a Spouse who is a Beneficiary but not a DOMA Spouse, determined as if such Spouse were a DOMA Spouse),
the need to prevent the eviction of the Participant from his principal residence or foreclosure on the mortgage of a Participant’s 

  
 49 

	 	
principal residence, payment for burial or funeral expenses for the Participant’s deceased parent, DOMA Spouse, Spouse that is a Beneficiary, children or dependents (as defined in
Section 152 of the Code and, for taxable years beginning on or after January 1, 2005, without regard to Section 152(d)(1)(B) of the Code), and expenses for the repair of damage to the Participant’s principal residence that would
qualify for the casualty deduction under Section 165 of the Code. 

  

	 	c.	The determination of whether a distribution is necessary to satisfy an immediate and heavy financial need shall be made on the basis of all relevant facts and circumstances. A distribution will be deemed to satisfy an
immediate and heavy financial need if it is not in excess of the amount of the immediate and heavy financial need of the Participant (grossed up to reflect the income taxes that will be assessed on the distribution, if the Participant so requests),
the Participant has obtained all distributions (other than hardship distributions) under all plans maintained by the Company, has elected to receive cash dividends on TimkenSteel Common Shares pursuant to Article VIII, Section F, and the Participant
agrees that all Wage Reduction Contributions and all other Participant contributions to all retirement plans maintained by the Company will be suspended until six (6) months after receipt of the hardship distribution. 

 

	 	d.	 Such election may be made at any time, but not more frequently than once a year for reasons other than the payment of post-secondary education
tuition. Elections for the payment of post-secondary education tuition 

  
 50 

	 	
may be made as often as every calendar quarter, and may be made in addition to a withdrawal for a non-tuition payment reason. All withdrawal elections shall be made by a Participant on written
forms supplied by the Plan Administrator for that purpose. Such distributions shall be processed immediately following the completion of the application procedure. 

10.         A Participant may obtain a loan from the Trust upon proper application to the Trust
pursuant to procedures established by the Plan Administrator. The Participant may borrow only the assets in his Account. The nature and amount of the loan must conform to the following rules and limits: 

 

	 	a.	The minimum loan amount is $1000. 

  

	 	b.	The maximum loan amount is fifty percent (50%) of the Participant’s Beneficial Loan Interest, provided, that no loan may be greater than $50,000, reduced by the highest outstanding loan balance from the Plan
during the one (1)-year period ending on the day before the date on which such loan is made. The Trustee will accept only the Participant’s Accrued Benefit as collateral for loans. 

 

	 	c.	The term of the loan cannot exceed four (4) years. The term of a loan may be extended beyond four (4) years for a Participant on military leave from the Company with the term of extension not to exceed the
length of such military service. 

  

	 	d.	A Participant may have only one (1) loan from this Plan in effect at any one time and may apply for only one (1) loan within each twelve (12)-month period. 

  
 51 

	 	e.	The Plan Administrator will establish the rate of interest to be charged on all loan balances. This rate of interest will be one percent (1%) in excess of the prime rate as published in the Wall Street Journal the
first business day of the month in which the loan is granted. A Participant on military leave from the Company may be entitled to the interest rate reduction provided in the Soldiers’ and Sailors’ Civil Relief Act of 1940.

  

	 	f.	The loan shall be repaid by the Participant, if the Participant is an active Employee, through payroll deduction as established by the loan agreement. If the Participant is not an active Employee, the Participant and
the Company shall agree to a repayment schedule which shall be incorporated in the loan agreement. The loan may be repaid in full at a date earlier than provided in the loan agreement with no penalty. Interest paid by the Participant will be
credited directly to the Participant’s Account. The loan fee of not more than $50.00 per loan will be paid by the Participant at the time the loan is obtained and a loan maintenance fee of no more than $3.75 per quarter will be assessed during
the term of the loan for loans obtained after a date no earlier than February 1, 2012. 

  

	 	g.	 The loan amount will be taken on a pro-rata basis from the Beneficial Loan Interest in all investment options at the time of the loan. If a
Participant has selected TimkenSteel Common Shares as an investment option, the Participant can choose whether the pro-rata loan amount is taken from the Participant’s ESOP Account or Non-ESOP Account. Repayments will be redeposited into the
Participant’s current investment options and contributions using the current ratio. No repayments will be deposited in ESOP Accounts. 

  
 52 

	 	h.	If a Participant does not repay a loan which he or she may have from the Plan, the Trustee will declare such loan to be in default when the loan is in arrears of repayment for more than ninety (90) days. The
Trustee may take steps to preserve Plan assets, if necessary, in the event of such default. Once default has been established, the amount of the loan in default (unpaid principal and the interest accrued thereon) shall be treated as a distribution
from the Plan in the Plan Year in which the default occurs. The amount of the default will not constitute part of subsequent distributions from the Trust. 

  

	 	i.	The proceeds of the loan cannot be applied toward the purchase of any securities. 

  

	 	j.	Loan repayments may be suspended under this Plan as permitted by Section 414(u) of the Code. 

  

	 	k.	Loans may be applied for on any business day. Loan applications shall be made through the interactive voice response system or the website of the Plan’s recordkeeper. 

 

	    	11. 	a.	 When a Participant has satisfied the eligibility requirements of the Plan, the Company may transfer the Participant’s Account balance
under another qualified defined contribution plan or a conduit individual retirement account which authorizes such transfers to the Plan. The Plan Administrator may establish such non-discriminatory restrictions and rules 

  
 53 

	 	
applicable to such transfers from the Plan and transfers to the Plan as it may determine to be necessary or desirable to maintain the qualified status of the Plan. In no event shall any amount be
transferred to the Trust from a defined benefit pension plan or a money purchase pension plan. 

  

	 	b.	The Company may transfer a Participant’s Account under the Plan to another qualified defined contribution plan maintained by the Company, when the Participant transfers employment from an employee group covered by
the Plan to an employee group not so covered, provided that the other plan accepts such transfers. Accounts so transferred shall be subject to such rights, restrictions, and features (including vesting provisions) applicable to assets in similar
accounts contributed to and held under the other plan. 

  

	 	c.	 If any portion of a Participant’s benefit is transferred in a distribution calendar year with respect to that Participant in order to satisfy the
minimum distribution rules in Article III, Section B, Paragraph 6, the transferor plan must determine the amount of the required minimum distribution with respect to that Participant for the calendar year of the transfer using the Participant’s
benefit under the transferor plan before the transfer. If any portion of a Participant’s benefit is transferred in the Participant’s second distribution calendar year, but on or before the Participant’s required beginning date, in
order to satisfy Article III, Section B, Paragraph 6, the transferor plan must determine the amount of the minimum distribution requirement for the Participant’s first 

  
 54 

	 	
distribution calendar year based on the Participant’s benefit under the transferor plan before the transfer. The transferor plan may satisfy the minimum distribution requirement for the
calendar year of the transfer (and the prior year if applicable) by segregating the amount which must be distributed from the Participant’s benefit and not transferring that amount. Such amount may be retained by the transferor plan and must be
distributed on or before the date required under Article III, Section B, Paragraph 6, of the Plan. 

12.         If overpayments or underpayments of benefits under the Plan have been made to a
Participant or Beneficiary, the amount of benefits will be appropriately adjusted, provided that the correction of any underpayments shall not result in the payment of interest to a Participant or Beneficiary on any such underpaid amounts. 

 

	C.	EQUITY DETERMINATION 

 1.         The Company
may amend or revoke the Wage Reduction Contribution election of any Participant at any time, if the Company determines that such revocation or amendment is necessary to ensure that the annual addition to a Participant’s Account for any Plan
Year will not exceed the limitations of Article II, Section C, Paragraph 1, or to ensure that the discrimination tests of Section 401(k) or 401(m) of the Code are met for such Plan Year. The discrimination tests shall be (1) that the
Employees eligible to benefit under this Plan shall satisfy the nondiscrimination provisions of Section 410(b)(1) of the Code and (2) that the actual deferral percentage for Highly Compensated Employees (as defined in Article I,
Section 18) for such Plan Year bears a relationship to the actual deferral percentage for all other eligible Employees for the preceding Plan Year which meets either of the following tests: 

  
 55 

	 	a.	the actual deferral percentage for the group of Highly Compensated Employees is not more than the actual deferral percentage of all other eligible Employees multiplied by 1.25, or 

 

	 	b.	the excess of the actual deferral percentage for the group of Highly Compensated Employees over that of all other eligible Employees is not more than two (2) percentage points, and the actual deferral percentage
for the group of Highly Compensated Employees is not more than the actual deferral percentage of all other eligible Employees multiplied by two (2). 

For purposes of this Section, the actual deferral percentage for a specified group of Employees for a Plan Year shall be the average of the
ratios (calculated separately for each Employee in such group) of: 
  

	 	a.	the amount of Wage Reduction Contributions actually paid to the Trust on behalf of each such Employee for such Plan Year, to 

  

	 	b.	the Employee’s compensation (as defined in Section 414(s) of the Code) for such Plan Year. 

 For
purposes of determining whether the Plan satisfies the actual deferral percentage test, all Wage Reduction Contributions that are made under two or more plans that are aggregated for purposes of satisfying Sections 401(a)(4) and 410(b) of the Code
(other than Section 410(b)(2)(A)(ii) of the Code), are to be treated as made under a single plan. If two or more plans are permissively aggregated for purposes of satisfying Section 401(k) of the Code, the aggregated plans must also
satisfy Sections 401(a)(4) and 410(b) of the Code as though they were a single plan. In calculating the actual deferral percentage, the actual deferral ratio of a Highly Compensated Employee will be determined by treating all plans subject to
Section 401(k) 

  
 56 

 
of the Code under which the Highly Compensated Employee is eligible (other than those that may not be permissively aggregated) as a single plan and in the event that such plans have different
plan years, all Wage Reduction Contributions made during the Plan Year under all such plans shall be aggregated. Notwithstanding the foregoing, plans that are not permitted to be aggregated under Treasury Regulations issued under Section 401(k)
of the Code shall be treated as separate arrangements. 
 2.         The Company may amend or revoke
the Wage Reduction Contributions election of any Participant at any time, if the Company determines that such revocation or amendment is necessary to insure that the discrimination tests of Section 401(m) of the Code are met for such Plan Year.
The discrimination tests shall be that the actual contribution percentage for Highly Compensated Employees (as defined in Article I, Section 18) for such Plan Year bears a relationship to the actual contribution percentage for all other
eligible Employees for the preceding Plan Year which meets either of the following tests: 
  

	 	a.	the actual contribution percentage for the group of Highly Compensated Employees is not more than the actual contribution percentage of all other eligible Employees multiplied by 1.25, or 

 

	 	b.	the excess of the actual contribution percentage for the group of Highly Compensated Employees over that of all other eligible Employees is not more than two (2) percentage points, and the actual contribution
percentage for the group of Highly Compensated Employees is not more than the actual contribution percentage of all other eligible Employees multiplied by two (2). 

  
 57 

 For purposes of this Section, the actual contribution percentage for a specified group of
Employees for a Plan Year shall be the average of the ratios (calculated separately for each Employee in such group) of: 
  

	 	a.	the amount of any Wage Reduction Contributions that are treated by the Company as matching contributions to the Plan, to 

  

	 	b.	the Employees’ compensation (as defined in Section 414(s) of the Code) for such Plan Year. 

 For
purposes of determining whether the Plan satisfies the actual contribution percentage test of Section 401(m) of the Code, all matching contributions that are made under two or more plans that are aggregated for purpose of satisfying Sections
401(a)(4) and 410(b) of the Code (other than Section 410(b)(2)(A)(ii) of the Code), are to be treated as made under a single plan. If two or more plans are permissively aggregated for purposes of satisfying Section 401(m) of the Code, the
aggregated plans must also satisfy Sections 401(a)(4) and 410(b) of the Code as though they were a single plan. In calculating the actual contribution percentage, the actual contribution ratio of a Highly Compensated Employee will be determined by
treating all plans subject to Section 401(m) of the Code under which the Highly Compensated Employee is eligible (other than those that may not be permissively aggregated) as a single plan and in the event that such plans have different plan
years, all matching contributions made during the Plan Year under all such plans shall be aggregated. Notwithstanding the foregoing, plans that are not permitted to be aggregated under Treasury Regulations issued under Section 401(k) of the
Code shall be treated as separate arrangements. 

  
 58 

 3.         In the event that the Plan should fail to meet
the test set forth in Article III, Section C, Paragraph 1, the amount of excess contributions for a Highly Compensated Employee for a Plan Year is to be determined by the following leveling methods: 

 

	 	a.	the total dollar amount of excess contributions is determined by reducing contributions on behalf of Highly Compensated Employees in the order of their deferral percentages, beginning with the highest of such
percentages and continuing until the actual deferral percentage test is satisfied; 

  

	 	b.	the amount determined in a. above is reallocated beginning with the Highly Compensated Employee with the highest dollar amount of contributions taken into account in performing the actual deferral percentage test to
equal the dollar amount of the Highly Compensated Employee with the next highest dollar amount of such contributions and continuing in succeeding order of the Highly Compensated Employees until all excess aggregate contributions are accounted for as
determined in a. above; 

  

	 	c.	each Highly Compensated Employee will receive a distribution of his portion of excess aggregate contributions determined in step b. above. 

For each Highly Compensated Employee, the amount of excess contributions is equal to the total Wage Reduction Contributions on behalf of the
Participant. 
 Excess contributions (and income allocable thereto through the last day of the Plan Year in which such excess contributions
were made) are distributed in accordance with this Article III, Section C, Paragraph 3, only if such excess contributions (and allocable income) are designated by the Company as a distribution of excess contributions (and income) and are distributed
to the appropriate Highly Compensated Employees after the close of the Plan Year in which the excess contributions occurred and within twelve months after the close of such Plan Year. 

  
 59 

 A corrective distribution of excess contributions (and income) is includable in gross income of
the Participant in the taxable year of the Participant in which it is distributed. 
 The amount of excess contributions to be distributed
under this Article III, Section C, Paragraph 3, with respect to a Participant for a Plan Year shall be reduced by any excess Wage Reduction Contribution elections under Article II, Section C, previously distributed to such Participant for the
Participant’s taxable year ending with or within such Plan Year. The amount of excess Wage Reduction Contribution elections that may be distributed under Article II, Section C, with respect to a Participant for a calendar year shall be reduced
by any excess contributions previously distributed with respect to such Participant for the Plan Year beginning with or within such calendar year. In the event of a reduction under this paragraph, the amount of excess contributions includable in the
gross income of the Participant and the amount of excess contributions reported by the Company as includable in the gross income of the Participant shall be reduced by the amount of the reduction under this Paragraph. 

4.         In the event that the Plan should fail to meet the test set forth in Article III, Section
C, Paragraph 2, the amount of excess aggregate contributions for a Highly Compensated Employee for a Plan Year is to be determined by the following leveling methods: 
  

	 	a.	the total dollar amount of excess aggregate contributions is determined by reducing contributions on behalf of Highly Compensated Employees in the order of their contribution percentages, beginning with the highest of
such percentages and continuing until the actual contribution percentage test is satisfied; 

  
 60 

	 	b.	the amount determined in a. above is reallocated beginning with the Highly Compensated Employee with the highest dollar amount of contributions taken into account in performing the actual contribution percentage test to
equal the dollar amount of the Highly Compensated Employee with the next highest dollar amount of such contributions and continuing in succeeding order of the Highly Compensated Employees until all excess aggregate contributions are accounted for as
determined in a. above; 

  

	 	c.	each Highly Compensated Employee will receive a distribution of his portion of excess aggregate contributions determined in step b. above. 

The amount of excess aggregate contributions with respect to an Employee for a Plan Year shall be determined only after first determining the
excess contributions that are treated as Employee contributions for the Plan Year due to recharacterization. For each Highly Compensated Employee, the amount of excess aggregate contributions is equal to the total Wage Reduction Contributions,
treated as matching contributions, on behalf of the Participant. 
 Excess aggregate contributions (and income allocable thereto through the
last day of the Plan Year in which such excess contributions were made) are distributed in accordance with this Article III, Section C, Paragraph 4, only if such excess aggregate contributions (and allocable income) are designated by the Company as
a distribution of excess aggregate contributions (and income) and are distributed to the appropriate Highly Compensated Employees after the close of the Plan Year in which the excess aggregate contributions occurred and within twelve months after
the close of the following Plan Year.

 ARTICLE IV - GENERAL CONDITIONS CONCERNING THE PLAN 

 

	A.	MERGER, CONSOLIDATION, OR TRANSFER 

 In case of any merger or consolidation with, or
transfer of assets or liabilities to, any other plan, the benefits which would be paid to each Participant in this Plan (if this Plan terminated immediately after the merger, consolidation, or transfer) shall be equal to or greater than the benefit
each Participant would have been entitled to receive immediately before the merger, consolidation, or transfer, (if this Plan had then terminated). 
  

	B.	NON-ALIENATION OF PARTICIPANTS’ INTERESTS 

1.         No right to the monies contributed by a Participant under this Plan, nor in any assets held
by the Trustee, shall be subject in any manner to alienation, assignment, encumbrance, pledge, sale, or transfer of any kind prior to being distributed to the Participant as provided in the Plan. However, the Trustee is granted in the Trust
Agreement a lien on Trust assets for the payment of Trustee fees and expenses. If at any time prior thereto a Participant shall attempt to alienate, assign, encumber, pledge, sell, or otherwise transfer his or her right to any shares or monies held
by the Trustee, such attempted alienation, assignment, encumbrance, pledge, sale, or transfer shall be of no effect. To the extent permitted by law, the interest of a Participant shall also be protected from involuntary attachment, garnishment, or
levy. In the event of an attempted attachment, garnishment, or levy of the Participant’s interest in the Trust, the Participant will be promptly notified; but the Trustee shall have no obligation to resist such action. In no event shall any
person be entitled to the distribution of shares or the payment of monies held by the Trustee prior to the time when distribution is to be made to the Participant as provided in the Plan. 

  
 62 

 2.         Section B, Paragraph 1, above shall not apply
if the attachment or garnishment of the Participant’s interest in the Trust is to be made pursuant to a qualified domestic relations order, as determined under the procedures of this Plan. A domestic relations order is a judgment, decree, or
order that relates to the provision of child support, alimony payments, or marital property rights to a DOMA Spouse, former DOMA Spouse, child, or other dependent of a Participant and is made pursuant to a state domestic relations law. A domestic
relations order is qualified if it creates or recognizes the existence of an Alternate Payee’s right to, or assigns to an Alternate Payee the right to, receive all or a portion of the benefits payable to a Participant under the Plan, specifies
(a) the name and last known mailing address of the Participant and of each Alternate Payee covered under the order, (b) the amount or percentage of the Participant’s benefits to be paid to any Alternate Payee or the manner in which
such amount or percentage is to be determined, (c) the number of payments or the period to which the order applies, and (d) each plan to which the order relates. Such order cannot require the Plan to provide any type or form of benefits,
or any option, not otherwise provided under the Plan; it cannot require the Plan to provide increased benefits (determined on the basis of actuarial value), and it cannot require the payment of benefits to an Alternate Payee which are required to be
paid to another Alternate Payee under another order previously determined to be a qualified domestic relations order. 

3.         Each Alternate Payee under a qualified domestic relations order shall have the right from
time to time to file with the Company a written request regarding the time and manner of payment of the Alternate Payee’s interest in the Plan pursuant to such qualified domestic relations order. Provided such qualified domestic relations order
complies with the Code, such request shall be considered by the Company and shall be acted upon in accordance with the terms of such qualified domestic relations order. The options available to an Alternate Payee shall be those set forth in Article
III, Section B, Paragraph 3, unless otherwise modified by the qualified domestic relations order, provided that said qualified domestic relations order cannot 

  
 63 

 
enlarge the options available under Article III, Section B, Paragraph 3. If an Alternate Payee so desires, distribution of an Alternate Payee’s interest in the Trust may be distributed to
such Alternate Payee, as soon as such qualified domestic relations order is approved by the Company and by the court. 
  

	C.	CONDITIONS TO THE EFFECTIVENESS AND CONTINUANCE OF THE PLAN 

1.         The Company will not be required to make any contributions (Wage Reduction Contributions or
Company Contributions) to the 401(k) Trust required to be established under this Plan or to place any part of the Plan into operation, unless and until it shall have received from the Internal Revenue Service a currently effective ruling or rulings,
satisfactory to the Company, that such Trust is a qualified Trust under Sections 401(a), 401(k), and 401(m) of the Code, and exempt from Federal Income Tax under Section 501(a) of the Code. Continued contributions to the Trust and operation of
the Plan shall be conditioned upon retaining such favorable ruling or rulings from the Internal Revenue Service. 

2.         The Company will not be required to make any contributions (Wage Reduction Contributions or
Company Contributions) to the 401(k) Trust required to be established under this Plan or to place any part of the Plan into operation, unless and until it shall have determined that no action will be taken by the Securities and Exchange Commission
concerning such Trust or any information contained or omitted in a registration statement for the Plan. Continued contributions to the Trust and operation of the Plan shall be conditioned upon further determinations by the Company that the
Securities and Exchange Commission will take no action concerning the Trust or any information contained or omitted in a registration statement for the Plan. 

  
 64 

 3.         In the event the Plan fails to qualify under
the applicable provisions of the Code, initially or as amended, the contributions shall be returned to the Company and the Participants. 

  
 65 

 ARTICLE V - ADMINISTRATION OF THE PLAN 

 

	A.	PLAN ADMINISTRATION 

 1.        The Plan
Administrator shall have full and complete discretionary authority with respect to all matters that arise in connection with the administration of this Plan, including, but not limited to, all decisions, findings of fact, power to construe said
Plan, to interpret language of the Plan, to determine all questions that shall arise hereunder, including questions on eligibility and participation of Employees and all matters necessary for it to administer the Plan. The decision of the Plan
Administrator on any matter is final and binding on all. 
 2.        The Plan established by this
Agreement is maintained for the exclusive benefit of Participants and Beneficiaries, and the Plan’s terms, including those relating to coverage and benefits, are legally enforceable. 

3.        A Plan Administrative Committee shall be appointed by the Plan Administrator. The Plan
Administrative Committee shall be responsible for assisting the Plan Administrator in its duties with respect to administration of the Plan. The Plan Administrative Committee shall perform its role without any discretionary authority or control. No
individual member of the Plan Administrative Committee shall have authority to make any decision on his own, but rather shall provide input to the Plan Administrator with respect to the exercise of its duties hereunder. The Plan Administrative
Committee will give input to the Plan Administrator with respect to all determinations as to the right of any persons to benefits under the Plan in accordance with the governing Plan documents. 

4.        The Investment Committee shall be responsible for the management of investments for the
Plan. The Investment Committee may, from time to time, retain the services of one or more persons or firms designated as an Investment Manager, as described below, for the management of (including the power to acquire and dispose of) all or any part
of the Trust. 

  
 66 

 
The Investment Committee will also be responsible for the selection of investment options to be available to Participants for investment of their accounts under the Plan. The Investment Committee
may establish an investment policy statement for the Plan and shall regularly assess the holding of TimkenSteel Common Shares in the Trust. The Company, as plan sponsor, shall determine the composition of the Investment Committee. The Investment
Committee will act as a committee, with no single individual of such Investment Committee responsible or able to control the Investment Committee’s decision. 

Any external firm or person designated as an “Investment Manager” must be registered as an investment advisor under the Investment
Advisors Act of 1940, a bank (as defined in that Act), or an insurance company qualified to perform, manage, acquire or dispose of trust assets under the laws of more than one State of the United States. Each such Investment Manager shall
acknowledge in writing that it is a fiduciary with respect to the assets of the Trust under its authority and management. The Investment Committee may modify or terminate the designation and authority of any Investment Manager from time to time. So
long as and to the extent that any designation is in effect, the Trustee shall invest and reinvest that portion of the Trust assigned to an Investment Manager in accordance with the instructions received from such Investment Manager, and, with
respect to such portion of the Trust managed by such Investment Manager, shall follow any instructions received by it from such Investment Manager. The Trustee shall be under no duty to review the investments made or held in any portion of the Trust
over which an Investment Manager has been given investment authority nor shall it be under any obligation to invest or otherwise manage any assets of the Trust which are subject to the management of such Investment Manager or Managers. Such assets
shall expressly be held by such Investment Manager as custodian of such assets. 

  
 67

	    	1. 	a.	 The Plan Administrative Committee will give input to the Plan Administrator with respect to all determinations as to the right of any persons
to benefits under the Plan. Any denial by the Plan Administrative Committee of a claim for benefits under the Plan by a claimant, which may be a Participant or Beneficiary will be stated in writing by the Plan Administrative Committee and delivered
or mailed to the claimant within a reasonable period of time, but not later than 90 days after receipt of the claim by the Plan, unless the Plan Administrative Committee determines that special circumstances require an extension of time for
processing the claim. Written notice of the extension shall be furnished to the claimant prior to the termination of the initial 90-day period. The extension notice shall indicate the special circumstances requiring an extension of time and the date
by which the Plan Administrative Committee expects to render the benefit determination, which cannot exceed a period of 90 days from the end of the initial period. 

 

	 	b.	Manner and Content of Notification of Benefit Determination. The Plan Administrative Committee shall provide a claimant with written or electronic notification of any adverse benefit determination. The notification
shall set forth in a manner calculated to be understood by the claimant: 

  

	 	(i)	The specific reason or reasons for the adverse determination; 

  

	 	(ii)	Reference to the specific plan provisions on which the determination is based;

	 	(iii)	A description of any additional material or information necessary for the claimant to perfect the claim and an explanation of why such material or information is necessary;

	    	2. 	a.	 If any dispute shall arise between any Participant or Beneficiary applying for a benefit and the Plan Administrative Committee or between any
Participant or Beneficiary applying for a benefit and the Company, as to such Participant’s or Beneficiary’s entitlement to a benefit or the amount of his benefit, such dispute may be disposed of in the manner provided for in the
Adjustment of Grievances, commencing with the last step in the grievance procedure preceding arbitration of the collective bargaining agreement in effect at the time such action is taken. 

 

	 	b.	 Any Participant or Beneficiary who wishes to submit such a dispute to such step of the grievance procedure must have a notice of his intention to do
so filed by the Representative of the International Union with the Administrator postmarked within sixty (60) days from the date of the notice to him of the action to which he objects. The Participant or Beneficiary shall state clearly and
concisely, in such notice of his intention to submit such dispute to such step of the grievance procedure, all facts 

  
 70 

	 	
which are the basis of his grievance; and if he claims that any Article or Articles of this Plan are involved, he shall specify such Article or Articles. The notice from the Administrator shall
advise such Participant or Beneficiary of his right to submit such dispute to such step of the grievance procedure within said time. 

  

	 	c.	The arbitrator, in deciding any such dispute and only insofar as necessary to decide such dispute, shall have authority only to interpret and apply the provisions of this Plan to the facts as presented in evidence to
him, but he shall not have the authority to add to or subtract from or, in any way, to alter or amend any of such provisions. The decision of the arbitrator on such dispute, which shall properly have been referred to him, shall be final and binding
upon the Company, the Union, Participant or Beneficiary, and the Plan Administrative Committee unless said decision was procured or induced by corruption, fraud, or undue means or was beyond the scope of the arbitrator’s authority herein
provided. 

 3.        If no appeal to arbitration is taken in accordance with Section
C hereof from any decision of the Plan Administrative Committee either awarding or denying a benefit under this Plan, or modifying or reversing any earlier decision awarding or denying such benefit, such decision of the Plan Administrative Committee
shall be final and binding upon said Participant or Beneficiary or any person on his behalf and upon the Union. 

  
 71 

 ARTICLE VI - AMENDMENT OF 401(k) PLAN 

A.         The Company expects to continue this Plan indefinitely, but the Company has the right to
amend the Plan in any other respect and in any manner not inconsistent with the 2012 401(k) Agreement, as such may be modified by the TimkenSteel MOU (the “401(k) Agreement”). Any such amendment shall be in writing. All Participants and
all persons claiming any interest hereunder shall be bound thereby. No amendment: 
  

	 	1.	shall have the effect of vesting in the Company any interest in any property held subject to the terms of the Plan; 

  

	 	2.	shall cause or permit any property held subject to the terms of the Plan to be diverted to purposes other than the exclusive benefit of Participants and their Beneficiaries; 

 

	 	3.	shall reduce the interest of a Participant in the Trust property as of that time or his or her right to enjoy such interest without the written consent of the Participant; or 

 

	 	4.	shall increase the duties or liabilities of the Trustee without its written consent. 

B.         An amendment to the Plan may not reduce the benefits accrued to any Participant unless
(1) such amendment is necessary to establish or maintain the qualification of the Plan under the Code or to conform the Plan to the requirements of ERISA or other applicable legislation, or (2) if not so necessary, and the amendment is
effective retroactively, such amendment is in accordance with Section C below. 

  
 72 

 C.        An amendment may reduce the Accrued Benefit of
participants as of the date of the adoption of the amendment, provided that: 
  

	 	1.	the amendment is adopted no later than 2-1/2 months after the end of the Plan Year in which the amendment becomes effective; 

  

	 	2.	the accrued benefits of participants as of the beginning of the Plan Year in which the amendment becomes effective are not reduced; and 

 

	 	3.	the amendment shall not take effect until (a) a notice of such amendment is filed with the Secretary of Labor and (b) either the Secretary of Labor has approved such amendment or, if the Secretary of Labor has
neither approved nor disapproved such amendment, ninety days have elapsed since the date on which such notice was filed. 

D.        If an amendment changes the vesting provisions, any Participant with at least three years of
service on the date of adoption, or, if later, the effective date of the amendment, may, within ninety days after he is notified of his right to do so, elect to have the amount of his vested benefit determined on the basis of the Plan provisions in
effect immediately prior to the effective date of the amendment. 
 E.        An amendment may not
reduce the vesting percentage of any Participant as of the later of (1) the effective date of the amendment or (2) the date of the adoption of the amendment. 

F.        Neither the consent of any Participant nor of any other payee is required for any amendment
to the Plan. 
 G.        In the event that amendments to this Plan are necessary or desirable for
the purpose of (1) obtaining a favorable ruling by the Internal Revenue Service concerning the qualification of or any matter arising under this Plan, (2) clarifying any ambiguity, correcting any apparent error, or supplying any omission
from the provisions of this Plan, or (3) facilitating or improving the administration of this Plan, such amendments may be made by the Company. 

  
 73 

 ARTICLE VII - TERMINATION OF 401(k) PLAN 

A.         The Plan may be terminated in whole or in part by the Company at any time, except to the
extent that such termination would violate the 401(k) Agreement. Upon a partial termination, the procedure and allocations applicable to a total termination of the Plan will apply to the group or groups of Participants for whom this Plan terminates.

 Upon termination of the Plan, the rights of each Participant are non-forfeitable with respect to the Plan benefits accrued to the date of
such termination, to the extent that such benefits are then funded and subject to any curtailment and reduction necessary for qualification or continued qualification under any tax law, or as is necessary for this Plan to meet the requirements of
ERISA or any other applicable law. The available Plan assets will be disposed of through the distribution of assets as outlined in Article III. 

The Plan Administrator is authorized to make any necessary adjustment in the above procedures and allocations applicable at termination of the
Plan in order to meet any requirements imposed on the Plan pursuant to any of the terms of ERISA. 

  
 74 

 ARTICLE VIII - ESOP PROVISIONS 

A.        Establishment of ESOP - An employee stock ownership plan (“ESOP”) that is
intended to meet the requirements of Section 4975(e)(7) of the Code shall be established as a component of the Plan. Such component of the Plan is designed to invest primarily in TimkenSteel Common Shares and consists of the ESOP Accounts of
all Participants. This component of the Plan is segregated as a stock bonus plan as defined in Treasury Regulation Section 1.401-1(b)(1)(iii). This Article VIII is effective notwithstanding any other provision of the Plan to the contrary or to
the extent that the implementation of any such other provision of the Plan would violate or otherwise limit the effect of this Article. 

B.        ESOP Account - The ESOP Account of each Participant shall be credited and debited
periodically during each Plan Year in which the ESOP is maintained with any additions or reductions in the number of TimkenSteel Common Shares held for such Participant in the Plan due to the reallocation of the investment of the Participant’s
Account, and with any stock and cash dividends paid on TimkenSteel Common Shares held in the Participant’s ESOP Account. The Trustee shall establish an ESOP Account in the name of each Participant and shall thereafter maintain a record thereof.
It shall be credited with all Wage Reduction Contributions, Rollover Contributions, and Company Contributions that the Participant has elected to invest in TimkenSteel Common Shares. 

C.        Nondiscrimination Test - For purposes of applying the tests under Article III,
Section C for any Plan Year in which (a) the ESOP is maintained and (b) the requirements of Section 401(k)(12) and 401(m)(11) of the Code are not satisfied, a single actual deferral percentage and actual contribution percentage, as
necessary, will be calculated for the group of Participants who are Highly Compensated Employees and a single actual deferral percentage and actual contribution percentage will be calculated, as necessary, for the group of all other Eligible

  
 75 

 
Employees for a Plan Year, by reason of the fact that, notwithstanding the ESOP, all Wage Reduction Contributions made in such Plan Year are allocated to the Participant’s Non-ESOP Wage
Reduction Contribution Account in such Plan Year (including any Wage Reduction Contributions that are invested in TimkenSteel Common Shares) and such account is not part of the ESOP portion of the Plan. 

D.        Investment Direction - To the extent a Participant’s Account includes amounts
originally allocated to an account subject to the Participant’s investment direction under Article III, Section A, Paragraph 1 of the Plan, including Company Contributions, the Participant shall retain the right to direct investments subject to
the provisions of Article III, Section A, Paragraph 1 of the Plan. 
 E.        Vesting
– A Participant shall have a non-forfeitable interest in the ESOP Account. 

F.        Payment of Dividends 

 

	 	(1)	 If administratively feasible and approved by the Company, any cash dividends paid with respect to TimkenSteel Common Shares in the ESOP as of the
record date shall be paid, at the election of the Participant (or his Beneficiary), to the Participant (or his Beneficiary), or to the Plan and reinvested in TimkenSteel Common Shares. Dividends paid to a Participant (or his Beneficiary) in
accordance with this election shall be paid in a manner and in accordance with procedures established by the Company (i) in cash directly to the Participant (or his Beneficiary), or (ii) to the Plan and subsequently distributed to the
Participant (or his Beneficiary) in cash no later than ninety (90) days after the close of the Plan Year in which the dividends are paid to the Plan. Dividends described 

  
 76 

	 	
in this Section F will be paid to the Plan and reinvested in TimkenSteel Common Shares with respect to any Participant (or Beneficiary) who does not affirmatively elect to have such dividends
paid to him. 

  

	 	(2)	For purposes of this Section F, “Participant” includes a Participant who is no longer employed by the Company but still has an Account in the Plan. 

 

	 	(3)	This Section F is intended to comply with Section 404(k) of the Code and shall be interpreted and construed accordingly. 

G.        Voting and Tender of ESOP TimkenSteel Common Shares - Each Participant, each
Beneficiary who has succeeded to the interest of a Participant and each Alternate Payee (“Eligible Participants and Beneficiaries”) in this Plan shall have the authority to direct the exercise of voting rights as to whole TimkenSteel
Common Shares held as part of the ESOP for the benefit of the Eligible Participant or Beneficiary as of the most current Valuation Date available preceding the record date for the shareholders’ meeting. The Trustee shall furnish the
Company’s Annual Report, Notice of Annual Meeting, Proxy Statement, Proxy Card and other shareholder information to each Eligible Participant and Beneficiary and shall solicit each Eligible Participant’s and Beneficiary’s vote; the
Company reserves the option to retain the Trustee to perform these services. All other TimkenSteel Common Shares held in the Trust, including shares not voted by Eligible Participants or Beneficiaries or not yet allocated to Eligible Participants or
Beneficiaries, are to be voted by the Trustee in conformity with applicable law, taking into account votes directed by Eligible Participants and Beneficiaries. 

H.        Right to Receive a Distribution of TimkenSteel Common Shares - In accordance with
Article III, Section B, Paragraph 4(a), distribution of a Participant’s ESOP Account when permitted or required under Article III, Section C, will be made in cash. 

  
 77 

 I.        Commencement of Distributions - If a
Participant or Beneficiary elects, distribution of the balance of a Participant’s ESOP Account will be made or will commence not later than one year after the close of the Plan Year: 

 

	 	a.	in which the Participant separates from service by reason of the attainment of normal retirement age under the Plan, age 70 1/2, disability, or death, or 

  

	 	b.	which is the fifth Plan Year following the Plan Year in which the Participant otherwise separates from service, unless the Participant is reemployed by the Company before distribution is required to begin under this
clause. 

 J.        Put Option 

 

	 	a.	 At such times as TimkenSteel Common Shares are not readily tradable on an established market at the time of distribution of a Participant’s ESOP
Account, the Company shall issue a Put Option to each Participant or Beneficiary receiving a distribution of TimkenSteel Common Shares from the Plan. The Put Option shall permit the Participant or Beneficiary to sell such TimkenSteel Common Shares
under a fair valuation formula during the sixty (60) consecutive day period following the date the TimkenSteel Common Shares were distributed to the Participant or Beneficiary, at which time the Put Option will temporarily lapse. Upon the close
of the Plan Year in which such temporary lapse occurs, an independent appraiser (meeting requirements similar to the requirements of the Treasury Regulations prescribed under Section 170(a)(1) of the Code) shall determine the value of the
TimkenSteel Common Shares, and the Trustee 

  
 78 

	 	
shall notify each Participant or Beneficiary who received a distribution who did not exercise the initial put option prior to its temporary lapse in the preceding Plan Year of the revised value
of the TimkenSteel Common Shares. The time during which the Put Option may be exercised shall recommence on the date such notice of revaluation is given and shall permanently terminate sixty (60) days thereafter. 

 

	 	b.	The Trustee may, in its discretion and with the consent of the Company, cause the Trust to assume the rights and obligations of the Company at the time the Put Option is exercised, insofar as the repurchase of
TimkenSteel Common Shares is concerned. The period during which the Put Option is exercisable shall not include any period during which the holder is unable to exercise such put option because the Company is prohibited from honoring it by Federal
and State law. The Company or the Trustee, as the case may be, must pay for TimkenSteel Common Shares sold pursuant to a Put Option no less rapidly than under one of the following two methods, as applicable: 

 

	 	(i)	 If a Put Option is exercised with respect to TimkenSteel Common Shares distributed as part of a total distribution (that is, a distribution of a
Participant’s or Beneficiary’s Account balance within one taxable year), then payment shall be made in substantially equal periodic payments (not less frequently than annually) commencing within thirty (30) days for the date of the
exercise of the Put Option and over a period not exceeding five 

  
 79 

	 	
years, with interest payable at a reasonable rate (as determined by the Company) on any unpaid installment balance, with adequate security provided, and without penalty for any prepayment of such
installments. 

  

	 	(ii)	If a Put Option is exercised with respect to TimkenSteel Common Shares distributed as part of an installment distribution, then the payment for such TimkenSteel Common Shares shall be made in a lump sum no later than
thirty (30) days after such Participant or Beneficiary exercises the Put Option. 

K.        Share Legend - TimkenSteel Common Shares held in ESOP Accounts or distributed by the
Trustee from ESOP Accounts may include such legend restrictions on transferability as the Company may reasonably require in order to assure compliance with applicable Federal and State securities laws. 

L.        Diversification - Participants in the Plan will be able to direct investments of
their entire Account. These Participants will be able to direct their Account, from TimkenSteel Common Shares, into other investment options available under the Plan. This provision satisfies Section 401(a)(28) of the Code. 

M.        Limitation on Period of Distribution - Unless otherwise elected, the distribution of
a Participant’s ESOP Account will be in substantially equal periodic payments (not less frequently than annually) over a period not longer than the greater of (i) five years, or (ii) if the balance of the Participant’s ESOP
Account is in excess of $1,015,000 (which amount may be adjusted periodically by the Internal Revenue Service to reflect cost-of-living increases), five years plus one additional year (but not more than five additional years) for each $200,000
(which amount may be adjusted periodically by the Secretary of the Treasury to reflect cost-of-living increases) or fraction thereof by which such balance exceeds $1,015,000 (as adjusted). 

  
 80 

 N.        Other Sections Superseded - This Article
VIII supersedes any other provision of the Plan solely to the extent that such other provision conflicts with the terms of this Article VIII or is inconsistent with the treatment of the portion of the Plan so designated as an ESOP. 

  
 81 

 ARTICLE IX – TIMKEN COMMON STOCK FUND 

 

	A.	GENERAL 

 1.        In addition to the
investment options described in Article III, Section A, Paragraph 1, an investment fund consisting primarily of common shares of Timken (the “Timken Common Stock Fund”) shall be maintained in the Plan. Except for cash or cash equivalent
investments determined by the Investment Committee to be required to facilitate Participant transactions out of the Timken Common Stock Fund, the Timken Common Stock Fund shall be invested exclusively in Timken Common Shares. Any cash dividends paid
with respect to Timken Common Shares shall be paid to the Plan and reinvested initially in the same investment options the Participant has selected for his Wage Reduction Contributions and Rollover Contributions or, if the Participant has made no
such elections, reinvested in any investment option or options, excluding the Timken Common Stock Fund, selected in a manner determined by the Investment Committee until such time as the Participant selects investment options. 

2.        The Timken Common Stock Fund shall be a “frozen” fund initially holding the Timken
Common Shares received from the Prior Plan in connection with the Spinoff. No Wage Reduction Contributions, Rollover Contributions or Company Contributions may be invested in the Timken Common Stock Fund and a Participant may not request a fund
transfer to the Timken Common Stock Fund. A Participant may, however, request fund transfers on any business day from the Timken Common Stock Fund to any other investment option pursuant to the rules for fund transfers described in Article III,
Section A, Paragraph 2. 
 3.        The Timken Common Stock Fund is maintained in recognition of
the fact that Transferred Participants may have a personal and professional dedication to, and history of investment in, Timken, and that offering the Timken Common Stock Fund as an investment option provides Transferred Participants with the
ability to preserve their personal affiliation with Timken through investment if they so choose. 

  
 82 

 4.        In light of the historical relationship between
the Company and Timken, and the availability of other investment options under the Plan through which Participants may construct a diversified portfolio of investments consistent with their individual desired level of risk and return, the Company
intends that the Timken Common Stock Fund be maintained as a design feature of the Plan, without regard to the investment return of the Timken Common Stock Fund in comparison to any performance measure that might be appropriate for any other
investment option. No Plan fiduciary shall have the authority to direct the sale of Timken Common Shares or to remove the Timken Common Stock Fund as an investment option, provided that the Investment Committee may remove the Timken Common Stock
Fund as an investment option and sell the remaining Timken Common Shares if the Investment Committee determines that (i) the level of continued investment by Participants in the Timken Common Stock Fund is not sufficient to reasonably justify
the administrative and recordkeeping expense of maintaining the fund, or (ii) no prudent investor would choose to invest any assets in Timken Common Shares, even as part of a diversified portfolio based on the investor’s individual risk
and return preferences and the Plan’s available investment options. 
  

	B.	VOTING AND TENDER OF TIMKEN COMMON SHARES. 

 Eligible Participants and Beneficiaries (as
defined in Article VIII, Section G) in this Plan shall have the authority to direct the exercise of voting rights as to whole Timken Common Shares for the benefit of the Eligible Participant or Beneficiary as of the most current Valuation Date
available preceding the record date for the shareholders’ meeting. The Trustee shall furnish Timken’s Annual Report, Notice of Annual Meeting, Proxy Statement, Proxy Card and other shareholder information to each Eligible Participant and
Beneficiary and shall solicit each 

  
 83 

 
Eligible Participant’s and Beneficiary’s vote; the Company reserves the option to retain the Trustee to perform these services. All other Timken Common Shares held in the Trust,
including shares not voted by Eligible Participants or Beneficiaries, are to be voted by the Trustee in conformity with applicable law, taking into account votes directed by Eligible Participants and Beneficiaries. 

  
 84 

 ARTICLE X - GENERAL PROVISIONS 

 

	    	A. 	(1)	 The Plan is established under, and its validity, construction and effect shall be governed by, the laws of the State of Ohio, except to the
extent governed by ERISA. 

  

	 	(2)	The parties to the Trust intend that the Trust be exempt from taxation under Section 501(a) of the Code, and any ambiguities in its construction shall be resolved in favor of an interpretation which will effect
such intention. 

 B.        The Plan is not and shall not be deemed to constitute a
contract between the Company and any Employee, or to be a consideration for, or an inducement to, or a condition of, the employment of any Employee. Nothing contained in the Plan shall give or be deemed to give an Employee the right to remain in the
employment of the Company or to interfere with the right to be retained in the employ of the Company, any legal or equitable right against the Company, or to interfere with the right of the Company to discharge or retire any Employee at any time.

  

	    	C. 	(1)	 Savings Clause. If any provision or provisions of the Plan shall for any reason be invalid or unenforceable, the remaining provisions
of the Plan shall be carried into effect, unless the effect thereof would be to materially alter or defeat the purposes of the Plan. 

  

	 	(2)	Headings. Headings and titles of sections and subsections within the Plan document are inserted solely for convenience of reference. They constitute no part of the Plan itself and shall not be considered in the
construction of the Plan. 

  
 85 

	 	(3)	Family Aggregation. Notwithstanding anything to the contrary in the Plan, the family aggregation rules do not apply after December 31, 1996. 

D.        Except as provided in this Paragraph, Plan assets shall not revert to the Company nor be
diverted for any purposes other than the exclusive benefit of Participants or their Beneficiaries; and a Participant’s vested interest shall not be subject to divestment. As provided in Section 403(c)(2) of ERISA, the actual amount of a
contribution made by the Company (or the current value of the contribution if a net loss has occurred) may revert to the Company if: 
  

	 	(1)	such contribution is made by reason of a mistake of fact; 

  

	 	(2)	initial qualification of the Plan under Section 401 (a) of the Code is not received and a request for such qualification is made within the time prescribed under Section 401(b) of the Code (the existence
of and contributions under the Plan are hereby conditioned upon such qualification); or 

  

	 	(3)	such contribution is not deductible under Section 404 of the Code (such contributions are hereby conditioned upon such deductibility) in the taxable year of the Company for which the contribution was made.

 The reversion to the Company must be made (if at all) within one year of the mistaken payment of the contribution, the date
of denial of qualification, or the date of disallowance of deduction, as the case may be. A Participant shall have no rights under the Plan with respect to such reversion. 

  
 86 

 E.        Commencing with a transaction with an effective
date of October 1, 2006, Plan Participants who exchange any amount out of a mutual fund or a similar type of product or fund under the Plan will be prohibited from purchasing shares of the same mutual fund through an exchange transaction for 30
calendar days (the “Trade Control Policy”). 
 The Trade Control Policy will not apply to the following: 

 

	 	(1)	money-market mutual funds. 

  

	 	(2)	actively managed separate accounts or lifestyle portfolios - mutual fund companies and other investment managers may impose additional trade control policies as a requirement for the Plan to include their products in
the Plan lineup, or as an underlying security in an actively managed separate account or lifestyle type of portfolio. 

  

	 	(3)	purchase transactions: 

  

	 	(a)	contribution processing, including Participant payroll, Company contributions, loan repayments, and rollovers. 

  

	 	(b)	fund dividends or capital gain distributions. 

  

	 	(4)	redemption transactions: 

  

	 	(a)	distributions, loans, and in-service withdrawals from the Plan. 

  

	 	(b)	Plan termination or at the discretion and direction of the Plan sponsor or other fiduciary. 

  

	 	(c)	payment of fund or Account fees. 

  

	 	(5)	conversions of shares from one class to another in the same fund. 

  

	 	(6)	re-registration of shares. 

  
 87 

 The Trade Control Policy will also not apply to Timken Common Shares or TimkenSteel Common Shares
because these are not mutual funds similar types of products or funds to which this policy applies. 
 Transactions initiated by the
Plan’s service provider or a similar program will be exempt from the Trade Control Policy. Reallocation and rebalancing transactions initiated by Plan Participants (whether the Participant is acting alone or utilizing an investment advisor,
investment advisory service or other Plan feature) will not be exempt from the Trade Control Policy. 
 Executed by TimkenSteel
Corporation at Canton, Ohio, on June 30, 2014, effective as of June 30, 2014, except as otherwise specifically provided.
