THIS NON-QUALIFIED STOCK OPTION AWARD (this “Award”) dated as of #Grant Date# (the “Grant Date”) is entered into by and between Dorman Products, Inc. (the “Company”) and #Participant Name# (the “Participant”).

1.Grant of Non-Qualified Stock Option. Effective as of the Grant Date, pursuant to the Dorman Products, Inc. 2018 Stock Option and Stock Incentive Plan (the “Plan”), the Company hereby grants to Participant a Non-Qualified Option to purchase #Number of Shares Granted# of Common Stock (the “Option”) at #Grant Price# (the “Exercise Price”) , subject to the terms and conditions set forth in this Award and the Plan.

2.Vesting of Option.

(a)Subject to the provisions of Sections 2(b) and (c), the Option shall vest 25% on each one-year anniversary of the Grant Date beginning on the first anniversary of the Grant Date (each a “Vesting Date”), provided that Participant remains employed by or providing service to the Company on such Vesting Date. The vesting of portions of the Option shall be cumulative, but shall not exceed 100% of the Shares subject to the Option. If the foregoing schedule would produce fractional Shares, the number of Shares that vest shall be rounded down to the nearest whole Share and the fractional Shares will be accumulated so that the resulting whole Share will be included in the number of Shares that become vested on the last Vesting Date.

(b)Upon a Change in Control, 100% of the unvested portion of the Option shall vest and become exercisable.

(i)100% as of the date of Participant’s death; or

(ii)100% as of the date of Participant’s termination of employment

Except as provided above, upon the termination of employment or service of Participant, any unvested portion of the Option will immediately and automatically, without any action on the part of the Company, be forfeited and cancelled.

To the extent of any inconsistency between the terms of this Agreement and such Employment Agreements, on the one hand, and the terms of the Plan, on the other hand, the terms of the Plan shall prevail.

(ii)The restrictions contained in any Employment Agreement and this Award are necessary for the protection of the business and goodwill of the Company and are considered by Participant to be reasonable for such purpose.

Accordingly, Participant agrees that if Participant breaches or threatens to breach any of the covenants contained in this Award or in any Employment Agreement, in addition to any other remedy which may be available to the Company under such Employment Agreements, at law or in equity, the Company shall be entitled to (x) cease or withhold any payment of Shares to Participant pursuant to this Award, including the return of any previously delivered Shares or proceeds recognized upon any sale or other disposition of those Shares; and/or (y) institute and prosecute proceedings in any court of competent jurisdiction for specific performance and injunctive relief to prevent the breach or any threatened breach thereof without bond or other security or a showing that monetary damages will not provide an adequate remedy. Participant agrees to disclose in advance the existence and terms of the restrictions and covenants contained in this Award and in any Employment Agreements to any employer or service recipient by whom Participant might be employed or retained during the time in which such restrictive covenants in such Employment Agreements are in effect.
