Forward-Looking Statements

This Form 8-K contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act. Forward-looking statements include statements regarding the anticipated closing date of the transaction and anticipated future results. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include words like “believe”, “expect”, “anticipate”, “estimate”, and “intend” or future or conditional verbs such as “will”, “would”, “should”, “could” or “may”. Certain factors that could cause actual results to differ materially from expected results include; the merger may involve unexpected costs, liabilities or delays; the inability to obtain the necessary regulatory or shareholder approvals or to obtain them in a timely fashion; the reaction of the companies’ customers, employees and counterparties to the proposed merger; the outcome of any legal proceedings related to the merger; the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement; increased competitive pressures; changes in the interest rate environment; changes in general economic conditions; legislative and regulatory changes that adversely affect the business in which Sunnyside Bancorp, Inc., Sunnyside Federal and Rhodium are engaged; changes in the securities markets; and other risks and uncertainties set forth in Sunnyside Bancorp’s filings with the Securities and Exchange Commission, including its most recently filed Annual Report on Form 10-K, subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the SEC, which are available on the SEC’s website at www.sec.gov. Undue reliance should not be placed on the forward-looking statements, which speak only as of the date hereof. None of Sunnyside Bancorp, Inc., Sunnyside Federal or Rhodium undertake, and specifically disclaim any obligation, to publicly release the result of any revisions that may be made to update any forward-looking statement to reflect the events or circumstances after the date on which the forward-looking statement is made, or reflect the occurrence of unanticipated events, except to the extent required by law.
