EX-10

This Non-Qualified Stock Option Agreement (the “Agreement”) is effective as of <GRANT DATE> (the “Grant Date”), by and between The Hanover Insurance Group, Inc., a Delaware corporation (the “Company”), and <PARTICIPANT NAME> (“Participant” or “you”). Capitalized terms used without definition herein shall have the meanings set forth in The Hanover Insurance Group 2022 Long-Term Incentive Plan (as it may be amended from time to time, the “Plan”).

WHEREAS, the Company considers it desirable and in the best interests of the Company that Participant be given an opportunity to acquire a proprietary interest in the Company in the form of an option to purchase shares of Stock.

NOW, THEREFORE, for and in consideration of the foregoing and the mutual covenants and promises hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Grant of Option. The Administrator hereby grants to Participant a non-statutory stock option (the “Stock Option”) to purchase <NUMBER OF OPTIONS> shares of Stock (the “Shares”), for a price of <GRANT PRICE> per share (the “Option Price”), which is not less than the per-Share Fair Market Value on the Grant Date. The Stock Option is intended to be, and is hereby designated, a non-statutory option that does not qualify as an incentive stock option as defined in Section 422.

Vesting. Subject to the terms of this Agreement and the Plan, and provided Participant remains continuously an Employee of the Company or one of its Affiliates (the Company and its Affiliates hereinafter referred to as “THG”) through the applicable vesting date except as set forth in Section 4 below, unless earlier terminated, forfeited, relinquished or expired, the Stock Option shall vest and become exercisable in the following cumulative installments:

On the first two vesting dates set forth above, to the extent the Stock Option would otherwise become vested and exercisable with respect to a fractional Share, such fractional Share shall not vest and the number of Shares becoming vested and exercisable on such vesting date shall be rounded down so that the Stock Option is only exercisable with respect to a whole number of Shares. In the event the vesting date falls on a day that is not a business day (i.e., a weekend day or holiday on which banks are not generally open in the Commonwealth of Massachusetts), the vesting date shall be the next following day that is a business day.

1 Pursuant to Mr. Farber’s Offer Letter dated September 21, 2016, in the event he is involuntarily terminated by the company without cause, or terminates employment for “good reason,” he is entitled to one year’s additional vesting credit.

(a) Termination for Cause. If Participant's Employment is terminated for Cause or occurs in circumstances that in the sole discretion of the Administrator would have constituted grounds for Participant’s Employment to be terminated for Cause, effective immediately prior to such termination, the Stock Option, whether or not vested, shall be automatically cancelled and forfeited and shall be returned to the Company for no consideration.

(b) Voluntary Termination. Except as set forth in Section 4(f) below, if Participant voluntarily terminates his/her Employment, effective immediately prior to such termination, any portion of the Stock Option that is not then vested shall be automatically cancelled and forfeited and shall be returned to the Company for no consideration, and such portion of the Stock Option that is then vested and exercisable shall remain exercisable until the earlier of (i) the last day of the three (3) month period following the date of such termination, or (ii) the Expiration Date.

(c) Disability. If Participant is Disabled prior to the date this Stock Option becomes fully vested and exercisable pursuant to Section 3 of this Agreement, this Stock Option, to the extent then outstanding and unvested, shall automatically vest in full and become exercisable on the date Participant is Disabled. To the extent all or any portion of this Stock Option is outstanding and exercisable on the date Participant is Disabled (determined after giving effect to the preceding sentence), the Stock Option (or portion thereof) shall remain exercisable until the earlier of (x) the last day of the one (1) year period following the date Participant is Disabled, or (y) the Expiration Date. For purposes of this subsection, Participant shall be “Disabled” if he or she has been unable, for a period of twelve consecutive months, to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment and has been receiving income replacement benefits for a period of twelve consecutive months under the Company’s Long-Term Disability Program. The date that Participant is Disabled for purposes of this Agreement is the twelve-month anniversary of the date Participant commences receiving such benefits under the Company’s Long-Term Disability Program.

If Participant ceases to receive benefits under the Company’s Long-Term Disability Program prior to becoming Disabled and immediately thereafter returns to active Employment, the Stock Option will continue to vest in accordance with Section 3 of this Agreement.

(d) Death. If Participant’s Employment is terminated due to his or her death prior to the date this Stock Option becomes fully vested and exercisable pursuant to Section 3 of this Agreement, this Stock Option, to the extent then outstanding and unvested, shall automatically vest in full and become exercisable on the date of Participant’s death. To the extent all or any portion of the Stock Option is outstanding and exercisable on the date Participant dies (determined after giving effect to the preceding sentence), the Stock Option (or portion thereof) shall remain exercisable until the earlier of (x) last day of the one (1) year period following the date Participant is terminated due to death, or (y) the Expiration Date.

(e) Covered Transaction/Change in Control. In the event of a Covered Transaction (other than a Change in Control, whether or not it is a Covered Transaction), the Administrator shall, with respect to the Stock Option, take one of the actions set forth in Sections 7(a)(1), 7(a)(2) or 7(a)(3) of the Plan. Notwithstanding the terms of the Plan, in the event of a Change in Control (whether or not it is a Covered Transaction), the following rules shall apply:

(i) Except as provided below in Section 4(e)(ii), in the event of a Change in Control, to the extent the Stock Option is outstanding and unvested immediately prior to the Change in Control, the Stock Option shall automatically vest in full as of immediately prior to such Change in Control.

(ii) Notwithstanding Section 4(e)(i) above, no acceleration of vesting shall occur with respect to the Stock Option if the Administrator reasonably determines in good faith prior to the occurrence of the Change in Control that this Award shall be honored or assumed, or new rights substituted therefor (such honored, assumed or substituted award hereinafter called an “Alternative Award”), by Participant's employer (or the parent or a subsidiary of such employer) immediately following the Change in Control, provided that any such Alternative Award must:

(A) be based on stock which is traded, or will be traded upon consummation of the Change in Control, on an established securities market;

(B) provide Participant (or each Participant in a class of Participants) with rights and entitlements substantially equivalent to or better than the rights, terms and conditions applicable under this Award, including, but not limited to, an identical or better vesting schedule and accelerated vesting provisions;

(D) have terms and conditions which provide that in the event that Participant's employment is involuntarily terminated (other than for Cause) or Participant terminates employment for “Good Reason” (as defined below), in either case, prior to the third anniversary of the Grant Date, Participant shall automatically vest in 100% of the Alternative Award and any conditions on Participant’s rights under, or any restrictions on transfer or exercisability applicable to, such Alternative Award shall be waived or shall lapse in full.

For this purpose, “Good Reason” shall mean the occurrence of one or more of the events listed below following a Change in Control:

(X) if Participant is a “Participant” (as that term is defined in the CIC Plan) in the Company’s Amended and Restated Employment Continuity Plan or its successor plan (the “CIC Plan”), the occurrence of any of the events enumerated under the definition of “Good Reason” applicable to Participant’s “Tier” Level as set forth in CIC Plan; or

(Y) if Participant is not a “Participant” in the CIC Plan, the occurrence of any of the following (A) a reduction in your rate of annual base salary as in effect immediately prior to such Change in Control; (B) a reduction in your annual short-term incentive compensation plan target award opportunity (but excluding the conversion of any cash incentive arrangement into an equity incentive arrangement of commensurate value or vice versa) from that which was in effect immediately prior to such Change in Control; or (C) any requirement that you relocate to an office more than 35 miles from the facility where you were located immediately prior to the Change in Control.

(iii) In the event Participant believes a “Good Reason” event has been triggered, Participant must give the Company (or Participant’s employer, if not the Company) written notice within 30 days of the first occurrence of such triggering event and a proposed termination date which shall not be sooner than 60 days nor longer than 90 days after the date of such notice. Such notice shall specify Participant’s basis for determining that “Good Reason” has been triggered. The Company (or Participant’s employer, if applicable) shall have the right to cure a purported “Good Reason” within 30 days of receipt of said notice and, if so cured, a termination of Participant’s Employment shall not be considered to be for “Good Reason” as a result of such event. If the event triggering “Good Reason” is not cured by the Company (or Participant’s employer, if applicable) within 30 days of its receipt of such notice, Participant shall be required to terminate his/her Employment on the proposed termination date in order to have his/her termination of Employment be treated as a “Good Reason” termination hereunder.

(iv) Notwithstanding Sections 4(e)(i) and 4(e)(ii) above, the Administrator may elect, in its sole discretion at a time prior to the effective date of the Change in Control, to accelerate all or any portion of the Stock Option.

(f) Retirement. If Participant’s Employment terminates as a result of his/her Retirement, and such termination occurs on or after the December 1st immediately following the Grant Date, this Stock Option shall remain outstanding and shall continue to become exercisable in accordance with the vesting schedule set forth in Section 3 as if Participant remained in Employment on each applicable vesting date and, to the extent vested and exercisable, the Stock Option shall remain exercisable by the Participant until the Expiration Date.

For the purpose of this Agreement, a termination of Employment shall be deemed to be a “Retirement” if all of the following conditions are satisfied: (i) Participant’s Employment terminates (other than for Cause), (ii) he or she is either (x) 65 years of age or older, as of the date of such termination, or (y) 60 years of age or older, as of the date of such termination and, immediately prior to such termination, Participant has been in continuous Employment for five or more years, and (iii)(1) Participant provides the Company not less than six months’ advanced written notice of Participant’s intent to retire (the “Notice Period”), and (2) Participant remains in continuous Employment and in good standing during such Notice Period and terminates Employment at the end of such Notice Period. The Company may, in its sole discretion waive, in whole or in part, the requirements of clause (iii) of the preceding sentence. In the event that Participant’s Employment is terminated for Cause during the Notice Period the Stock Option will be automatically cancelled and forfeited and shall be returned to the Company for no consideration.

(g) Involuntary Termination. If Participant’s Employment is terminated (other than as a result of the events set forth above in this Section 4), effective immediately prior to such termination, any portion of the Stock Option that is not then vested shall be automatically cancelled and forfeited and shall be returned to the Company for no consideration, and such portion of the Stock Option that is then vested and exercisable shall remain exercisable until the earlier of (i) the last day of three (3) month period following the date of termination, or (ii) the Expiration Date.

Exercise notices hereunder shall be in such form as is acceptable to the Administrator, including by electronic notice with electronic signature. If notice is provided by a person other than Participant, this Stock Option will not be deemed to have been exercised until the Administrator has received such evidence as it may require that the person exercising the Stock Option has the right to do so. Unless otherwise determined by the Administrator, such notices, and any other notices hereunder, must be in writing and, if to the Company, shall be delivered personally to the Human Resources Department or such other party as designated by the Company or mailed to its principal office and, if to Participant, shall be delivered personally or mailed to Participant at his or her address on the records of the Company.

Payment of the Option Price may be made in (a) shares of Stock (including through a “net exercise” (as set forth in subsection (b)), (b) by a “net exercise” arrangement pursuant to which the Company will reduce the number of shares of Stock that would otherwise be issued upon exercise of the Stock Option by a number of whole shares having a fair market value equal to the aggregate Option Price of the Stock Option, (c) cash or a combination of shares of Stock and cash, or (d) through a broker-assisted exercise program acceptable to the Administrator.

To the extent that the Option Price of this Stock Option is less than the fair market value of a share of Stock by $0.50 or more on the date described below (determined by using the closing price of a share of Stock on such date, or if the Stock is not traded on such date, the most recent date on which the Stock was traded), this Stock Option, to the extent then outstanding and vested, will be automatically exercised, without any action required on behalf of Participant, by a “net exercise” as described in clause (b) of the paragraph above, on (x) the Expiration Date, if Participant has remained continuously Employed from the Grant Date through the Expiration Date, or (y) the last day of the applicable post-termination of Employment exercise period of this Stock Option as set forth in Section 4 above, if the Employment of Participant was involuntarily terminated by the Company for reasons other than for Cause, was terminated by reason of death, being Disabled or Retirement, or was voluntarily terminated by Participant.

Non-Hire/Solicitation/Confidentiality/Code of Conduct. As a condition of Participant’s eligibility to receive this Stock Option and regardless of whether such Stock Option vests or is exercised, Participant agrees that he or she will (a) not, directly or indirectly, during the term of Participant’s Employment, and for a period of one year (two years if Participant terminates Employment by reason of Retirement) thereafter, hire, solicit, entice away or in any way interfere with THG’s relationship with, any of its officers or employees, or in any way attempt to do so or participate with, assist or encourage a third party to do so; (b) neither disclose any of THG’s confidential and proprietary information to any third party, nor use such information for any purpose other than for the benefit of THG and in accordance with THG’s policies; (c) not, during the term of Participant’s Employment, and for a period of one year (two years if Participant terminates Employment by reason of Retirement) thereafter, interfere with or seek to interfere with, THG’s relationships with any of its policyholders, customers, clients, agents or vendors; and (d) at all times comply with (i) THG’s Code of Conduct and other policies and procedures as in effect from time to time, and (ii) any non-competition, non-disclosure, non-solicitation or similar agreement he or she may have with the Company or any of its Affiliates. The terms of this Section 7 shall survive the expiration or earlier termination of this Agreement.

(a) Participant hereby acknowledges and agrees that in the event of any breach of Section 7 of this Agreement, the Company would be irreparably harmed and could not be made whole by monetary damages. Participant accordingly agrees to waive the defense in any action for injunctive relief or specific performance that a remedy at law would be adequate and that the Company, in addition to any other remedy to which it may be entitled at law or in equity, shall be entitled to an injunction or to compel specific performance of Section 7 of this Agreement.

(b) In addition to any other remedy to which the Company may be entitled at law or in equity (including the remedy provided in the preceding paragraph), Participant hereby acknowledges and agrees that in the event of any breach of Section 7 of this Agreement, Participant shall be required to refund to the Company the value received by Participant upon exercise of the Stock Option measured by the amount that the Stock Value exceeds the Option Price paid on exercise of the Stock Option; provided, however, that the Company makes any such claim, in writing, against Participant alleging a violation of Section 7 of this Agreement not later than two years following Participant’s termination of Employment (three years in the event of a termination by reason of Retirement). For purposes of this Agreement, the “Stock Value” shall be the sale price of the Shares issued upon exercise of the Stock Option, if and to the extent such Shares were sold on the date of such exercise; otherwise, the “Stock Value” shall be the closing price of Shares as reported on the New York Stock Exchange (or such other exchange or facility as is determined by the Administrator if the Shares are not then traded on the New York Stock Exchange) on the date of the exercise of the Stock Option.

12.

Entire Agreement; Counterparts. This Agreement and the Plan contains the entire understanding between the parties concerning the subject contained in this Agreement. Except for the Agreement and the Plan, there are no representations, agreements, arrangements, or understandings, oral or written, between or among the parties hereto, relating to the subject matter of this Agreement, that are not fully expressed herein. This Agreement may be signed in one or more counterparts, all of which shall be considered one and the same agreement.

15.

Construction. Whenever used in this Agreement, the singular number will include the plural, and the plural number will include the singular, and the masculine or neuter gender shall include the masculine, feminine, or neuter gender. The headings of the sections of this Agreement have been inserted for purposes of convenience and shall not be used for interpretive purposes. The Administrator shall have full discretion to interpret and administer this Agreement. Any actions or decisions by the Administrator in connection with this Agreement shall be conclusive and binding upon Participant.

17.

Taxes. The exercise of this Stock Option will give rise to “wages” subject to withholding. Participant expressly acknowledges and agrees that Participant’s rights hereunder, including the right to be issued Shares upon exercise, are subject to Participant promptly remitting to the Company in cash (or by such other means as may be acceptable to the Administrator in its discretion) any amounts determined by the Company to be required to be withheld. No Shares will be transferred pursuant to the exercise of this Stock Option unless and until the person exercising this Stock Option has remitted to the Company an amount sufficient to satisfy any federal, state, or local withholding tax requirements, or has made other arrangements satisfactory to the Company with respect to such taxes. Participant authorizes the Company to withhold such amount from any amounts otherwise owed to Participant. The Company may, at its option, withhold a sufficient number of Shares from Shares otherwise to be delivered upon exercise of this Stock Option to satisfy the minimum federal, state and local tax withholding due (or such greater number of Shares, but not in excess of the maximum withholding amount consistent with this Award being subject to equity accounting treatment under the Accounting Rules, as determined by, and in the sole discretion of, the Company) and remit the balance of the Shares to Participant. If this Stock Option is automatically exercised as provided in the last paragraph of Section 5 above or if Participant pays the Option Price through a “net exercise” of this Stock Option as provided by Section 5 above, the minimum federal, state and local tax withholding due in connection with the exercise of this Stock Option shall be satisfied by the Company withholding a sufficient number of Shares from Shares otherwise to be delivered upon exercise of this Stock Option to satisfy with minimum federal, state and local tax withholding due (or such greater number of Shares, but not in excess of the maximum withholding amount consistent with this Award being subject to equity accounting treatment under the Accounting Rules, as determined by, and in the sole discretion of, the Company).

The Company makes no representations to Participant with respect to the tax treatment of any amount paid or payable pursuant to this Award. While this Award is intended to be interpreted and operated to the extent possible so that any such amounts shall be exempt from the requirements of Section 409A, in no event shall THG be liable to Participant for or with respect to any taxes, penalties and/or interest which may be imposed upon any such amounts pursuant to Section 409A or any other federal or state tax law. To the extent that any such amount should be subject to Section 409A (or any other federal or state tax law), Participant shall bear the entire risk of any such taxes, penalties and or interest.

18.

Waiver of Jury Trial. By accepting this Award under the Plan, to the maximum extent permitted by law, Participant waives any right to a trial by jury in any action, proceeding or counterclaim concerning any rights under (a) the Plan, (b) any Award, or (c) any amendment, waiver, consent, instrument, document or other agreement delivered or which in the future may be delivered in connection with any of the foregoing, and agrees that any such action, proceedings or counterclaim shall be tried before a court and not before a jury.

19.

Additional Restrictions. The Administrator may cancel, rescind, withhold or otherwise limit or restrict the Stock Option (in whole or in part) at any time if Participant is not in compliance with all applicable provisions of this Agreement and the Plan, or if Participant breaches any agreement with THG, including with respect to the Code of Conduct or other policies of THG, or any non-competition, non-solicitation, confidentiality or other similar provisions. Without limiting the generality of the foregoing, the Administrator may recover the Stock Option and payments under or gain in respect thereto to the extent required to comply with Section 10D of the Securities Exchange Act of 1934, as amended, or any stock exchange or similar rule adopted under said Section. In addition, rights, payments and benefits under this Award shall be subject to repayment to, or recoupment by, THG in accordance with any clawback or recoupment policies and procedures that THG may adopt from time to time.

IN WITNESS WHEREOF, the parties hereto have entered into this Agreement as of the Grant Date.
