THE TIMKEN COMPANY Performance-Based Restricted Stock Unit Agreement

Payment of PRSUs. The PRSUs will become payable in accordance with the provisions of Section 6 of this Agreement if the Restriction Period lapses and Grantee’s right to receive payment for the PRSUs becomes nonforfeitable (“Vest,” “Vesting” or “Vested”) in accordance with Section 3 and Section 4 of this Agreement.

PRSUs Not Transferrable. None of the PRSUs nor any interest therein or in any Common Shares underlying such PRSUs will be transferable other than by will or the laws of descent and distribution prior to payment.

Vesting of PRSUs.

Subject to the terms and conditions of Section 4 and Section 5 of this Agreement, the PRSUs will Vest on the basis of the relative achievement of the Management Objective or Management Objectives approved by the Committee on the Date of Grant (the “Performance Metrics”) for the period from January 1, 2015 through December 31, 2017 (the “Performance Period”) as follows:

The applicable percentage of the PRSUs that shall be earned by Grantee for the Performance Period shall be determined by reference to the Performance Matrix for the Performance Period

In the event that the Company’s achievement with respect to one of the Performance Metrics is between the performance levels specified in the Performance Matrix, the applicable percentage of the PRSUs that shall be earned by Grantee for the Performance Period shall be determined by the Committee using straight-line interpolation; and

The Vesting of the PRSUs pursuant to this Section 3 or pursuant to Section 4 shall be contingent upon a determination of the Committee that the Performance Metrics, as described in this Section 3, have been satisfied.

If the Committee determines that a change in the business, operations, corporate structure or capital structure of the Company, the manner in which it conducts business or other events or circumstances render the Performance Metrics specified in this Section 3 to be unsuitable, the Committee may modify such Performance Metrics or any related minimum acceptable level of achievement, in whole or in part, as the Committee deems appropriate; provided, however, that no such action may result in the loss of the otherwise available exemption of the PRSUs under Section 162(m) of the Code.

All determinations involving the Performance Metrics set forth in this Section 3 shall be calculated based on U.S. Generally Accepted Accounting Principles in effect at the time the Performance Metrics are established without regard to any change in accounting standards that may be required by the Financial Accounting Standards Board after the Performance Metrics are established.

Subject to Section 3(a), Section 3(b) and Section 3(c), the PRSUs earned with respect to the Performance Period will Vest if Grantee is in the continuous employ of the Company or a Subsidiary from the Date of Grant through the last day of the Performance Period. For purposes of this Agreement, the continuous employment of Grantee with the Company or a Subsidiary will not be deemed to have been interrupted, and Grantee shall not be deemed to have ceased to be an employee of the Company or a Subsidiary, by reason of the transfer of Grantee’s employment among the Company and its Subsidiaries.

Alternative Vesting of PRSUs. Notwithstanding the provisions of Section 3 of this Agreement, and subject to the payment provisions of Section 6 hereof, Grantee shall Vest in some or all of the PRSUs under the following circumstances:

Death or Disability: If Grantee should die or become permanently disabled while in the employ of the Company or a Subsidiary, then Grantee shall Vest in a number of PRSUs equal to the product of (i) the number of PRSUs in which Grantee would have Vested in accordance with the terms and conditions of Section 3 if Grantee had remained in the continuous employ of the Company or a Subsidiary from the Date of Grant until the end of the Performance Period or the occurrence of a Change in Control to the extent a Replacement Award is not provided, whichever occurs first, multiplied by (ii) a fraction (in no case greater than 1) the numerator of which is the number of whole months from the first day of the Performance Period through the date of such death or permanent disability and the denominator of which is 36. PRSUs that Vest in accordance with this Section 4(a) will be paid as provided for in Section 6(a) of this Agreement. For purposes of this Agreement, “permanently disabled” means that Grantee has qualified for long-term disability benefits under a disability plan or program of the Company or, in the absence of a disability plan or program of the Company, under a government-sponsored disability program and is “disabled” within the meaning of Section 409A(a)(2)(C) of the Code.

Retirement: If Grantee should retire with the Company’s consent, then Grantee shall Vest in a number of PRSUs equal to the product of (i) the number of PRSUs in which Grantee would have Vested in accordance with the terms and conditions of Section 3 if Grantee had remained in the continuous employ of the Company or a Subsidiary from the Date of Grant until the end of the Performance Period or the occurrence of a Change in Control to the extent a Replacement Award is not provided, whichever occurs first, multiplied by (ii) a fraction (in no case greater than 1) the numerator of which is the number of whole months from the first day of the Performance Period through the date of such retirement and the denominator of which is 36. PRSUs that Vest in accordance with this Section 4(b) will be paid as provided for in Section 6(a) of this Agreement. For purposes of this Agreement, “retire with the Company’s consent” means: (i) the retirement of Grantee prior to age 62 under a retirement plan of the Company or a Subsidiary, if the Board or the Committee determines that his retirement is for the convenience of the Company or a Subsidiary; or (ii) the retirement of Grantee at or after age 62 under a retirement plan of the Company or a Subsidiary.

Change in Control:

Upon a Change in Control occurring during the Restriction Period while Grantee is an employee of the Company or a Subsidiary or during the period that Grantee is deemed to be in the continuous employ of the Company or a Subsidiary pursuant to Section 4(a), 4

For purposes of this Agreement, a “Replacement Award” means an award (A) of performance-based restricted stock units, (B) that has a value at least equal to the value of the PRSUs, (C) that relates to publicly traded equity securities of the Company or its successor in the Change in Control (or another entity that is affiliated with the Company or its successor following the Change in Control), (D) the tax consequences of which, under the Code, if Grantee is subject to U.S. federal income tax under the Code, are not less favorable to Grantee than the tax consequences of the PRSUs, (E) that vests upon a termination of Grantee’s employment with Company or its successor in the Change in Control (or another entity that is affiliated with the Company or its successor following the Change in Control) for Good Reason by Grantee or without Cause by such employer within a period of two years after the Change in Control based on actual performance through the date of such termination, and (F) the other terms and conditions of which are not less favorable to Grantee than the terms and conditions of the PRSUs (including the provisions that would apply in the event of a subsequent Change in Control). A Replacement Award may be granted only to the extent it conforms to the requirements of Treasury Regulation 1.409A-3(i)(5)(iv)(B) or otherwise does not result in the PRSUs or Replacement Award failing to comply with Section 409A of the Code. Without limiting the generality of the foregoing, the Replacement Award may take the form of a continuation of the PRSUs if the requirements of the preceding sentence are satisfied. The determination of whether the conditions of this Section 4(c)(ii) are satisfied will be made by the Committee, as constituted immediately before the Change in Control, in its sole discretion.

For purposes of Section 4(c)(ii), “Cause” will be defined not less favorably with respect to Grantee than: any intentional act of fraud, embezzlement or theft in connection with the Grantee’s

If a Replacement Award is provided, notwithstanding anything in this Agreement to the contrary, any outstanding PRSUs which at the time of the Change in Control are not subject to a “substantial risk of forfeiture” (within the meaning of Section 409A of the Code) will be deemed to be Vested at the time of such Change in Control and will be paid as provided for in Section 6(b) of this Agreement.

Divestiture: If Grantee’s employment with the Company or a Subsidiary terminates as the result of a divestiture, then Grantee shall Vest in a number of PRSUs equal to the product of (i) the number of PRSUs in which Grantee would have Vested in accordance with the terms and conditions of Section 3 if Grantee had remained in the continuous employ of the Company or a Subsidiary from the Date of Grant until the end of the Performance Period or the occurrence of a Change in Control to the extent a Replacement Award is not provided, whichever occurs first, multiplied by (ii) a fraction (in no case greater than 1) the numerator of which is the number of whole months from the first day of the Performance Period through the date of such termination and the denominator of which is 36. PRSUs that Vest in accordance with this Section 4(d) will be paid as provided for in Section 6(a) of this Agreement. For the purposes of this

Layoff: If (i) Grantee’s employment with the Company or a Subsidiary terminates as the result of a layoff and (ii) Grantee is entitled to receive severance pay pursuant to the terms of any severance pay plan of the Company in effect at the time of Grantee’s termination of employment that provides for severance pay calculated by multiplying Grantee’s base compensation by a specified severance period, then Grantee shall Vest in a number of PRSUs equal to the product of (x) the number of PRSUs in which Grantee would have Vested in accordance with the terms and conditions of Section 3 if Grantee had remained in the continuous employ of the Company or a Subsidiary from the Date of Grant until the end of the Performance Period or the occurrence of a Change in Control to the extent a Replacement Award is not provided, whichever occurs first, multiplied by (y) a fraction (in no case greater than 1) the numerator of which is the number of whole months from the first day of the Performance Period through the end of the specified severance period and the denominator of which is 36. PRSUs that Vest in accordance with this Section 4(e) will be paid as provided for in Section 6(a) of this Agreement. For purposes of this Agreement, a “layoff” shall mean the involuntary termination by the Company or any Subsidiary of Grantee’s employment with the Company or any Subsidiary due to (A) a reduction in force leading to a permanent downsizing of the salaried workforce, (B) a permanent shutdown of the plant, department or subdivision in which Grantee works, or (C) an elimination of position.

Forfeiture of PRSUs. Any PRSUs that have not Vested pursuant to Section 3 or Section 4 at the end of the Performance Period will be forfeited automatically and without further notice after the end of the Performance Period (or earlier if, and on such date that, Grantee ceases to be an employee of the Company or a Subsidiary prior to the end of the Performance Period for any reason other than as described in Section 4).

Form and Time of Payment of PRSUs.

General. Subject to Section 5 and Section 6(b), payment for Vested PRSUs will be made in cash or Common Shares (as determined by the Committee) between January 1, 2018 and March 15, 2018.

Other Payment Event. Notwithstanding Section 6(a), to the extent that the PRSUs are Vested on the date of a Change in Control, Grantee will receive payment for Vested PRSUs in cash or Common Shares (as determined by

Payment of Dividend Equivalents. With respect to each of the PRSUs covered by this Agreement, Grantee shall be credited on the records of the Company with dividend equivalents in an amount equal to the amount per Common Share of any cash dividends declared by the Board on the outstanding Common Shares during the period beginning on the Date of Grant and ending either on the date on which Grantee receives payment for the PRSUs pursuant to Section 6 hereof or at the time when the PRSUs are forfeited in accordance with Section 5 of this Agreement. These dividend equivalents will accumulate without interest and, subject to the terms and conditions of this Agreement, will be paid at the same time, to the same extent and in the same manner, in cash or Common Shares (as determined by the Committee) as the PRSUs for which the dividend equivalents were credited.

Detrimental Activity and Recapture.

Notwithstanding anything in this Agreement to the contrary, in the event that, as determined by the Committee, Grantee shall engage in Detrimental Activity during employment with the Company or a Subsidiary, the PRSUs will be forfeited automatically and without further notice at the time of that determination notwithstanding any other provision of this Agreement.

If a Restatement occurs and the Committee determines that Grantee is personally responsible for causing the Restatement as a result of Grantee’s personal misconduct or any fraudulent activity on the part of Grantee, then the Committee has discretion to, based on applicable facts and circumstances and subject to applicable law, cause the Company to recover all or any portion (but no more than 100%) of the PRSUs earned or payable to Grantee for some or all of the years covered by the Restatement. The amount of any earned or payable PRSUs recovered by the Company shall be limited to the amount by which such earned or payable PRSUs exceeded the amount that would have been earned by or paid to Grantee had the Company’s financial statements for the applicable restated fiscal year or years been initially filed as restated, as reasonably determined by the Committee. The Committee shall also determine whether the Company shall effect any recovery under this Section 8(b) by: (i) seeking repayment from Grantee; (ii) reducing, except with respect to any non-qualified deferred compensation under Section 409A of the Code,

Compliance with Law. The Company shall make reasonable efforts to comply with all applicable federal and state securities laws; provided, however, notwithstanding any other provision of this Agreement, the Company shall not be obligated to issue any of the Common Shares covered by this Agreement if the issuance thereof would result in violation of any such law.

Adjustments. Subject to Section 12 of the Plan, the Committee shall make any adjustments in the number of PRSUs or kind of shares of stock or other securities underlying the PRSUs covered by this Agreement that the Committee may determine to be equitably required to prevent any dilution or expansion of Grantee’s rights under this Agreement that otherwise would result from any (a) stock dividend, stock split, combination of shares, recapitalization or other change in the capital structure of the Company, (b) merger, consolidation, separation, reorganization or partial or complete liquidation involving the Company or (c) other transaction or event having an effect similar to any of those referred to in Section 10(a) or 10(b) hereof. Furthermore, in the event that any transaction or event described or referred to in the immediately preceding sentence shall occur, the Committee may provide in substitution of any or all of Grantee’s rights under this Agreement such alternative consideration as the Committee may determine in good faith to be equitable under the circumstances.

Withholding Taxes. If the Company is required to withhold federal, state, local, employment, or foreign taxes, or, to the extent permitted under Section 409A of the Code, any other applicable taxes, in connection with Grantee’s right to receive Common Shares under this Agreement (regardless of whether Grantee is entitled to the delivery of any Common Shares at that time), and the amounts available to the Company for such withholding are insufficient, it shall be a condition to the receipt of any Common Shares or any other benefit provided for under this Agreement that Grantee make arrangements satisfactory to the Company for payment of the balance of the taxes. Grantee may satisfy such tax obligation by paying the Company cash via personal check. Alternatively, Grantee may elect

Right to Terminate Employment. No provision of this Agreement will limit in any way whatsoever any right that the Company or a Subsidiary may otherwise have to terminate the employment of Grantee at any time.

Relation to Other Benefits. Any economic or other benefit to Grantee under this Agreement or the Plan will not be taken into account in determining any benefits to which Grantee may be entitled under any profit‑sharing, retirement or other benefit or compensation plan maintained by the Company or a Subsidiary and will not affect the amount of any life insurance coverage available to any beneficiary under any life insurance plan covering employees of the Company or a Subsidiary.

Amendments. Any amendment to the Plan will be deemed to be an amendment to this Agreement to the extent that the amendment is applicable to this Agreement; provided, however, that no amendment will adversely affect the rights of Grantee with respect to the Common Shares or other securities covered by this Agreement without Grantee’s consent. Notwithstanding the foregoing, the limitation requiring the consent of Grantee to certain amendments will not apply to any amendment that is deemed necessary by the Company to ensure compliance with Section 409A of the Code.

Severability. In the event that one or more of the provisions of this Agreement is invalidated for any reason by a court of competent jurisdiction, any provision so invalidated will be deemed to be separable from the other provisions of this Agreement, and the remaining provisions of this Agreement will continue to be valid and fully enforceable.

Governing Law. This Agreement is made under, and shall be construed in accordance with, the internal substantive laws of the State of Ohio.

Compliance with Section 409A of the Code. To the extent applicable, it is intended that this Agreement and the Plan comply with the provisions of Section 409A of the Code, so that the income inclusion provisions of Section 409A(a)(1) of the Code do not apply to Grantee. This Agreement and the Plan shall be
