SEVERANCE PAY PLAN

OF

RADIUS BANK

ARTICLE I

PURPOSE

Section 1.1 Statement of Purpose.

(a) The Bank adopts this Severance Pay Plan of Radius Bank for the benefit of its eligible Employees and those of other Participating Employers. The Bank recognizes that, as a wholly owned subsidiary of a public company, it will be subject to the possibility of a negotiated or unsolicited change of control which may result in a loss of employment for some of its Employees. The purpose of the Plan is to encourage the Bank’s Employees and those of other Participating Employers to continue working for their employers with their full time and attention devoted to their employer’s affairs by providing a severance benefit in the event of an Involuntary Severance following a Change of Control.

(b) The Bank also recognizes that it may be appropriate in certain circumstances other than a Change of Control to provide a severance benefit to Employees in the event of an Involuntary Severance, and thus the Plan provides for the payment of a severance benefit in circumstances other than a Change of Control as determined in the discretion of the Plan Administrator.

Section 1.2 Other Severance Plans, Policies, and Practices Superseded.

As of the Effective Date hereof, this Plan supersedes in its entirety any plan, policy, or practice of the Bank for the provision of the severance benefit to Employees, whether written or oral or formal or informal, and no severance benefit shall be provided to any individual whose employment terminates with the Bank on or after the Effective Date, except as provided under the terms of the Plan or as provided under the terms of a written, complete, and fully executed employment agreement or change of control agreement specifically providing for the payment of a severance benefit following termination of employment with the Bank.

The claimant shall be permitted to review pertinent documents. A decision shall be rendered by the Committee and communicated to the claimant not later than thirty (30) days after receipt of the claimant’s written request for review. However, if the Committee finds it necessary, due to special circumstances (for example, the need to hold a hearing), to extend this period and so notifies the claimant in writing, the decision shall be rendered as soon as practicable, but in no event later than one hundred twenty (120) days after the claimant’s request for review.
