Independent Bank Corp. and Rockland Trust Company 2019 Nonqualified Deferred Compensation Plan for Non-Employee Directors

Annual Enrollment. Each Participant who is eligible to participate in the Plan for any calendar year shall enroll by executing a Participation Agreement and completing all other forms as the Administrator may request. Participation in the Plan shall commence as of the date specified in the Participation Agreement.

Vesting. The Participant’s Account shall be fully vested at all times.

Deferral Elections. Participants may elect to defer receipt of all or any portion of their Fees. Before the beginning of a Plan Year, any Participant who wishes to defer receipt of any amount of his or her Fees must elect the amount of Fees to be deferred under the Plan for the upcoming Plan Year by completing a Participation Agreement. A Fee deferral election shall expire at the end of that calendar year (i.e., Fee deferral elections are not “evergreen”) and a new election must be made for each new calendar year. Deferral elections cannot be revoked or changed for a calendar year once the year has begun.

Crediting of Contributions. The Administrator shall credit each Participant’s Account under this Plan with an amount equal to the Participant’s Fee Deferral Percentage, as specified on such Participant’s Participation Agreement, at the time that such amount would otherwise have been payable to the Participant. The Administrator will establish separate bookkeeping accounts for each year’s Fee deferrals.

Investments. Participants shall have the right to direct the investment of their Accounts by choosing from among the investment alternatives made available by the Administrator. The Administrator shall credit each Participant’s Account with earnings or losses as reported to the Administrator by the trustee of the rabbi trust (if any) or as reported from an investment source. If the Participant does not provide timely or proper investment directions, the Administrator shall select a default investment in the sole discretion of the Administrator.

Initial Selection of Benefit Payment Dates. The Participant shall specify his or her Benefit Payment Date(s) on his Participation Agreement with respect to amounts deferred for a calendar year. Benefits will be paid in cash, no later than 60 days after each of the specified Benefit Payment Dates, unless the Participant elects annual installments on the Participation Agreement.

Delaying Benefit Payment Dates. A Participant may delay the timing of any scheduled Benefit Payment Date, provided that such change:

Separation from Service. With respect to amounts initially deferred under this Plan, if the Participant has a Separation from Service before the Participant’s next scheduled Benefit Payment Date, other than due to death or Disability, the Participant shall be paid the Participant’s Account, which shall continue to be credited with earnings until paid to the Participant. Such amount shall be paid in a cash lump sum no later than 60 days after the Participant’s Separation from Service date, unless the Participant timely and properly elected annual installments on his Participation Agreement (but may be delayed until 6 months after Separation from Service if the Participant is a Specified Employee), or unless the Participant previously elected on the Participation Agreement to not accelerate a scheduled payment upon his or her Separation from Service.

Death Benefit. If a Participant dies while he or she is a member of the Board, the Participant’s Beneficiary shall be entitled to payment of the Participant’s Account, which shall be paid as a cash lump sum, no later than 60 days after the Participant’s date of death. If a Participant dies following

Disability Benefit. If a Participant becomes Disabled while he or she is a member of the Board, but does not have a Separation from Service, the Participant shall be entitled to receive payment of his entire Account, calculated at time of the Disability determination and paid in a lump sum, within 60 days after the date of the Disability determination.

Code Section 409A. The Plan shall be interpreted to comply with Code Section 409A, and all provisions of the Plan shall be construed in a manner consistent with the requirements for avoiding taxes or penalties under Code Section 409A. While the Company and the Bank intend this Plan to comply with Code Section 409A, they do not represent or warrant to Participants that this Plan is compliant with Code Section 409A. Neither the Company nor the Bank nor the Administrator shall be liable for any additional taxes, penalties, or interest imposed as a result of noncompliance with Code Section 409A. With respect to installment payments, such payments will be treated as a “single payment” for purposes of the rules on subsequent deferral elections made in accordance with this Plan.

Administrator’s Duties. This Plan shall be administered by the Administrator. The Administrator shall have the authority to make, amend, interpret, and enforce all appropriate rules and regulations for the administration of this Plan and decide or resolve any and all questions, including interpretations of this Plan, as may arise.

Agents. The Administrator may, from time to time, employ other agents and delegate to them such administrative duties as it sees fit, and may from time to time consult with counsel who may be counsel to the Company or the Bank.

Binding Effect of Decisions. The decision or action of the Administrator in respect to any question arising out of or in connection with the administration, interpretation, and application of the Plan and the rules of regulations under this Plan shall be final, conclusive, and binding upon all persons having any interest in the Plan.

Indemnification. The Bank and the Company shall indemnify and hold harmless all individuals acting as the Administrator against any and all claims, loss, damage, expense, or liability arising from any action or failure to act with respect to this Plan, except in the case of gross negligence or willful misconduct.

Claim. Any person claiming a benefit, requesting an interpretation or ruling under the Plan, or requesting information under the Plan shall present the request in writing to the Administrator, which shall respond in writing within 30 days.

Denial of Claim. If the claim or request is denied, the written notice of denial shall state:

Review of Claim. Any person whose claim or request is denied, or who has not received a response within 30 days, may request review by notice given in writing to the Administrator. The claim or request shall be reviewed by the Administrator who may, but shall not be required to, grant the claimant a hearing. On review, the claimant may have representation, examine pertinent documents, and submit issues and comments in writing.

Final Decision. The decision on review shall normally be made within 60 days. If an extension of time is required for a hearing or other special circumstances, the claimant shall be notified and the time limit shall be 120 days. The decision shall be in writing and shall state the reasons and the relevant Plan provisions.

Arbitration. If a claimant continues to dispute the benefit denial based upon completed performance of this Plan and the Participation Agreement or the meaning and effect of the terms and conditions of them, then the claimant may submit the dispute to mediation, administered by the American Arbitration Association (“AAA”) (or a mediator selected by the parties) in accordance with the AAA’s Commercial Mediation Rules. If mediation is not successful in resolving the dispute, it shall be settled by arbitration administered by the AAA under its Commercial Arbitration Rules, and judgment on the award rendered by the arbitrator(s) may be entered in any court having jurisdiction.

Amendment. Notwithstanding anything contained in this Plan to the contrary, the Board reserves the exclusive right to freeze or to amend this Plan at any time, provided that no amendment to the Plan shall decrease or restrict any amount accrued prior to the amendment date.

Complete Termination. Subject to the requirements of Code Section 409A, in the event of complete termination of the Plan, the Plan shall cease to operate and the Bank shall pay out to each Participant his or her entire Account as of the date of termination of the Plan. A complete termination of the Plan shall occur only under the following circumstances and conditions:

Unfunded Plan. This Plan is intended to be an unfunded plan maintained primarily to provide deferred compensation benefits for a select group of management or highly compensated individuals, within the meaning of ERISA. This Plan is not intended to create an investment contract, but to provide tax planning opportunities and retirement benefits to eligible individuals who participate in the Plan.

Unsecured Creditor. The Participant’s interest in his or her Account is limited to the right to receive payments under the Plan, and the Participant’s position is that of a general unsecured creditor of the Company and the Bank.

Trust Fund. The Company or the Bank shall be responsible for the payment of all benefits provided under the Plan. At its discretion, the Company or the Bank may establish one or more rabbi trusts, with such trustees as the Board may approve, for the purpose of providing for the payment of such benefits. Such rabbi trust or trusts may be irrevocable, but the assets thereof shall be subject to the claims of the Company’s or the Bank’s creditors. To the extent any benefits provided under the Plan are actually paid from any such trust, the Company or the Bank shall have no further obligation with respect to them, but to the extent not so paid, such benefits shall remain the obligation of, and shall be paid by, the Company or the Bank.

Payment to Participant, Legal Representative or Beneficiary. Any payment to any Participant or the legal representative, Beneficiary, or to any guardian or committee appointed for the Participant or Beneficiary shall, to the extent thereof, be in full satisfaction of all claims hereunder against the Company or the Bank, which may require the Participant, legal representative, Beneficiary, guardian or committee, as a condition precedent to such payment, to execute a receipt and release in a form as shall be determined by the Company or the Bank.

Nonassignability. Neither a Participant nor any other person shall have any right to commute, sell, assign, transfer, hypothecate or convey in advance of actual receipt any amounts, payable which are, and all rights to which are, expressly declared to be un-assignable and nontransferable. No part of the amounts payable shall, prior to actual payment, be subject to seizure or sequestration for the payment of any debts, judgments, alimony, or separate maintenance owed by an Participant or any other person, nor be transferable by operation of law in the event of a Participant’s or any other person’s bankruptcy or insolvency.

Validity. In case any provision of this Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this Plan, but this Plan shall be construed and enforced as if such illegal and invalid provision had never been included.

Notice. Any notice or filing required or permitted to be given to the Administrator under the Plan

Successors. The provisions of this Plan shall bind and inure to the benefit of the Company, the Bank, and their successors and assigns. The term “successors” as used shall include any corporate or other business entity which shall, whether by merger, consolidation, purchase or otherwise acquire all or substantially all of the business and assets of the Company or the Bank, and successors of any such corporation or other business entity.

Acceleration of Payments. Except as specifically permitted by this Plan, no acceleration of the time or schedule of any payment may be made. Notwithstanding the foregoing, payments may be accelerated by the Bank, in accordance with the provisions of Treasury Regulation Section 1.409A-3(j)(4) and any subsequent guidance issued by the United States Department of the Treasury. Accordingly, payments may be accelerated, in accordance with requirements and conditions of the Treasury Regulations (or subsequent guidance) in the following circumstances: (i) as a result of certain domestic relations orders; (ii) in compliance with ethics agreements with the federal government; (iii) in compliance with ethics laws or conflicts of interest laws; (iv) in limited cash-outs (but not in excess of the limit under Code Section 402(g)(1)(B)); (v) to apply certain offsets in satisfaction of a debt of the Participant to the Bank; (vi) in satisfaction of certain bona fide disputes between the Participant and the Bank; or (vii) for any other purpose set forth in the Treasury Regulations and subsequent guidance.

Required Provisions. Any payments made to the Participant pursuant to this Plan or otherwise are subject to and conditioned upon compliance with 12 U.S.C. § 1828(k) and 12 C.F.R. Part 359 Golden Parachute and Indemnification Payments or any other rules and regulations promulgated under them.
