GENERAL PROVISIONS

8.1. Participant’s Rights Unsecured. To fund its obligations under the Plan, the Bank may elect to form a trust, or to utilize a pre-existing trust, to purchase and hold the alternative forms of assets which are permitted under the 401(k) Plan, including shares of Company Common Stock, subject to compliance with all applicable securities laws. If the Bank elects to use a trust to fund its obligations under the Plan, a Participant shall have no right to demand the transfer to him of stock or other assets from the Bank, or from such a trust formed or utilized by the Bank. Any assets held in a trust, including shares of Company Common Stock, may be distributed to a Participant in payment of part or all of the Bank’s obligations under the Plan. The right of a Participant or his designated beneficiary to receive a distribution hereunder shall be an unsecured claim against the general assets of the Bank, and neither the Participant nor a designated beneficiary shall have any rights in or against any specific assets of the Bank.

8.2. General Conditions. Except as otherwise expressly provided herein, all terms and conditions of the 401(k) Plan applicable to a 401(k) Allocation will also be applicable to a Supplemental Savings Deferred Allocation pursuant to this Plan. Nothing in this Plan shall operate or be construed in any way to modify, amend or affect the terms and provisions of the 401(k) Plan.

8.3. No Guarantee of Benefits. Nothing contained in the Plan shall constitute a guarantee by the Bank or any other person or entity that the assets of the Bank will be sufficient to pay any benefit hereunder.

8.4. No Enlargement of Employee Rights. No Participant shall have any right to receive a distribution of contributions made under the Plan except in accordance with the terms of the Plan. Establishment of the Plan shall not be construed to give any Participant the right to be retained in the service of the Bank.

5

8.5. Spendthrift Provision. No interest of any person or entity in, or right to receive a distribution under, the Plan shall be subject in any manner to sale, transfer, assignment, pledge, attachment, garnishment, or other alienation or encumbrance of any kind; nor may such interest or right to receive a distribution be taken, either voluntarily or involuntarily for the satisfaction of the debts of, or other obligations or claims against, such person or entity, including claims for alimony, support, separate maintenance and claims in bankruptcy proceedings.

8.6. Applicable Law. The Plan shall be construed and administered under the laws of the State of Connecticut to the extent such laws are not superseded by federal law.

8.7. Incapacity of Recipient. If any person entitled to a distribution under the Plan is deemed by the Bank to be incapable of personally receiving and giving a valid receipt for such payment, then, unless and until claim therefor shall have been made by a duly appointed guardian or other legal representative of such person, the Bank may provide for such payment or any part thereof to be made to any other person or institution then contributing toward or providing for the care and maintenance of such person. Any such payment shall be a payment for the account of such person and a complete discharge of any liability of the Bank and the Plan therefor.

8.8. Corporate Successors. The Plan shall not be automatically terminated by a transfer or sale of assets of the Bank or by the merger or consolidation of the Bank into or with any other company or other entity, but the Plan shall be continued after such sale, merger or consolidation only if and to the extent that the transferee, purchaser or successor entity agrees to continue the Plan. In the event that the Plan is not continued by the transferee, purchaser or successor entity, then the Plan shall terminate subject to the provisions of Section 7.2. Notwithstanding the above, the Plan shall terminate at the same time as the 401(k) Plan is terminated and all benefits hereunder shall become payable upon such termination.

8.9. Unclaimed Benefit. Each Participant shall keep the Bank informed of his current address and the current address of his designated beneficiary. The Bank shall not be obligated to search for the whereabouts of any person. If the location of a Participant is not made known to the Bank within three (3) years after the date on which payment of the Participant’s account may first be made, payment may be made as though the Participant had died at the end of the three-year period. If, within one additional year after such three-year period has elapsed, or, within three years after the actual death of a Participant, the Bank is unable to locate any designated beneficiary of the Participant, then the Bank shall have no further obligation to pay any benefit hereunder to such Participant or designated beneficiary and such benefit shall be irrevocably forfeited.

6

8.10. Limitations on Liability. Notwithstanding any of the preceding provisions of the Plan, neither the Bank nor any individual acting as employee or agent of the Bank shall be liable to any Participant, former Participant or other person for any claim, loss, liability or expense incurred in connection with the Plan.
