2.2.2 Hardship.

Article 6

Beneficiaries

6.1 Beneficiary Designations. The Director shall designate a beneficiary by filing a written designation with the Bank. The Director may revoke or modify the designation at any time by filing a new designation. However, designations will only be effective if signed by the Director and received and approved by the Bank during the Director’s lifetime. The Director’s beneficiary designation shall be deemed automatically revoked if the beneficiary predeceases the Director, or if the Director names a spouse as beneficiary and the marriage is subsequently dissolved. If the Director dies without a valid beneficiary designation, all payments shall be made to the Director’s estate.

6.2 Facility of Payment. If a benefit is payable to a minor, to a person declared incompetent, or to a person incapable of handling the disposition of his or her property (as determined by the Bank), the Bank may pay such benefit to the guardian, legal representative or person having the care or custody of such minor, incompetent person or incapable person. The Bank may require proof of incompetence, minority or guardianship as it may deem appropriate prior to distribution of the benefit. Such distribution shall completely discharge the Bank from all liability with respect to such benefit.

Article 7

Amendments and Termination

7.1 This Agreement may be amended or terminated only by a written agreement signed by the Bank and the Director.

7.2 Notwithstanding Section 7.1, the Bank may amend or terminate this Agreement at any time if, pursuant to legislative, judicial or regulatory action, continuation of the Agreement would (i) cause benefits to be taxable to the Director prior to actual receipt, or (ii) result in significant financial penalties or other significantly detrimental ramifications to the Bank. In no event shall this Agreement be terminated under this Section 7.2 without payment to the Director of the Deferral Account balance attributable to the Director’s Deferrals and interest credited on such amounts.

Article 8

Miscellaneous

8.1 Binding Effect. This Agreement shall bind the Director and the Bank, and their beneficiaries, survivors, executors, administrators and transferees.

8.2 No Guarantee of Service. This Agreement is not a contract for services. It does not give the Director the right to remain a Director of the Bank. It also does not require the Director to remain a Director nor interfere with the Director’s right to terminate services at any time.

8.3 Non-Transferability. Benefits under this Agreement cannot be sold, transferred, assigned, pledged, attached or encumbered in any manner.

8.4 Tax Withholding. The Bank is authorized to withhold any taxes that it believes are required to be withheld from the benefits provided under this Agreement.

8.5 Applicable Law. The Plan and all rights hereunder shall be governed by and construed according to the laws of the State of Connecticut, except to the extent preempted by the laws of the United States of America.

8.6 Recovery of Estate Taxes. If the Director’s gross estate for federal estate tax purposes includes any amount determined by reference to and on account of this Agreement, and if the beneficiary is other than the Director’s estate, then the Director’s estate shall be entitled to recover from the beneficiary receiving such benefit under the terms of the Agreement, an amount by which the total estate tax due by the Director’s estate, exceeds the total estate tax which would have been payable if the value of such benefit had not been included in the Director’s gross estate. If there is more than one person receiving such benefit, the right of recovery shall be against each such person. In the event the beneficiary has a liability hereunder, the beneficiary may petition the Bank for a lump sum payment in an amount not to exceed the lesser of the beneficiary’s liability hereunder and the balance remaining in the Deferral Account.

8.7 Unfunded Arrangement. The Director and, to the extent the Director’s beneficiary or estate have rights to benefits under this Agreement, are the general unsecured creditors of the Bank for the payment of benefits under this Agreement. The benefits represent the mere promise by the Bank to pay such benefits. The rights to benefits are not subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment, or garnishment by creditors. Any insurance which the Bank may have procured in connection with this Agreement on the Director’s life is a general asset of the Bank to which the Director, the Director’s beneficiary nor the Director’s estate have any preferred or secured claim.

8.8 Reorganization. In the event of any merger, consolidation or acquisition where the Bank or its parent holding company, SI Bancorp, Inc., is not the surviving entity or

6

resulting corporation, or upon transfer of all or substantially all of the assets of the Bank, this Agreement shall continue and be in full force and effect and shall be binding upon such surviving entity, resulting corporation, or transferee.

8.9 Entire Agreement. This Agreement constitutes the entire agreement between the Bank and the Director as to the subject matter hereof. No rights are granted to the Director by virtue of this Agreement other than those specifically set forth herein.

8.10 Administration. The Bank shall have powers which are necessary to administer this Agreement, including but not limited to:

8.10.1 Interpreting the provisions of the Agreement;

8.10.2 Establishing and revising the method of accounting for the Agreement;

8.10.3 Maintaining a record of benefit payments; and

8.10.4 Establishing rules and prescribing any forms necessary or desirable to administer the Agreement.

8.11 Named Fiduciary. For purposes of the Employee Retirement Income Security Act of 1974, if applicable, the Bank shall be the named fiduciary and plan administrator under the Agreement. The named fiduciary may delegate to others certain aspects of the management and operation responsibilities of the plan including the employment of advisors and the delegation of ministerial duties to qualified individuals.

IN WITNESS WHEREOF, the Director and a duly authorized Bank officer have signed this Agreement.
