EX-99: NEWS RELEASE

Item 2.02. Results of Operations and Financial Condition.

Item 8.01 Regulation FD Disclosure.

The following information is furnished to the Securities and Exchange Commission under both Item 2.02 and Item 8.01 of this Form 8-K.

On April 17, 2007, Sandy Spring Bancorp, Inc. issued a news release regarding its results of operations for the quarter ended March 31, 2007. The text of the press release is included as Exhibit 99 to this report.

Non-GAAP Financial Measure. Exhibit 99 includes disclosure and discussion of a traditional efficiency ratio that is a non-GAAP financial measure as defined in Commission Regulation G and Item 10 of Commission Regulation S-K. The Company has for many years used this traditional efficiency ratio as a measure of operating expense control and efficiency of operations. Management believes that this traditional ratio better focuses attention on the operating performance of the Company over time than does a GAAP based ratio, and is highly useful in comparing period-to-period operating performance of the Company’s core business operations. It is used by management as part of its assessment of its performance in managing noninterest expenses. However this measure is supplemental, and is not a substitute for an analysis of performance measures based on GAAP. Exhibit 99 also includes disclosure and discussion of the GAAP-based efficiency ratio and the differences between the two ratios. The traditional efficiency ratio used by the Company may not be comparable to GAAP or non-GAAP efficiency ratios reported by other financial institutions.

Sandy Spring Bancorp, Inc. has filed a registration statement with the SEC relating to a proposed merger transaction with CN Bancorp. The registration statement has become effective. A proxy statement/prospectus relating to that transaction has been distributed to shareholders of CN Bancorp. We urge investors to read the proxy-statement/prospectus and other documents filed and to be filed with the SEC in connection with the transaction or incorporated by reference in the proxy statement/prospectus, because they have contained or will contain important information. Investors may obtain these documents free of charge at the SEC’s web site (www.sec.gov). In addition, documents filed with the SEC by Sandy spring Bancorp, Inc. will be available free of charge from Shareholder Relations at 301-570-8338.

The directors, executive officers, and certain other members of management and employees of CN Bancorp are participants in the solicitation of proxies in favor of the transaction from the shareholders of CN Bancorp. Information about the directors and executive officers of CN Bancorp is included in its Annual Report on Form 10-KSB for the year ended December 31, 2006. Additional information regarding the interest of such participants is included in the proxy statement/prospectus and other relevant documents filed with the SEC.

Neither this Form 8-K nor Exhibit 99 shall constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of such securities in any jurisdiction in which such offer, solicitation

or sale is not permitted or would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
