Forward-Looking Statements and Factors Which May Affect Future Results

This Form 10-K contains forward-looking statements (within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities and Exchange Act of 1934 as amended) that are subject to risks and uncertainties. Forward-looking statements include information concerning possible or assumed future results of operations of the Company, projected or anticipated benefits, or events related to other future developments involving the Company or the industry in which it operates. Also, when verbs in the present tense such as “believes,” “expects,” “anticipates,” “continues,” “attempts” or similar expressions are used, forward-looking statements are being made. Stockholders should note that many factors, some of which are discussed elsewhere in this document and in the documents which we incorporate by reference, could affect the future financial results of the Company and could cause results to differ materially from those expressed in or incorporated by reference in this document. Those factors include fluctuations in interest rates, disruptions in credit markets, inflation, changes in the regulatory environment, government regulations and changes in regional and local economic conditions and changes in the competitive environment in the geographic and business areas in which the Company conducts its operations. As a result of such risks and uncertainties, the Company’s actual results may differ materially from such forward-looking statements. The Company does not undertake, and specifically disclaims any obligation to publicly release revisions to any such forward-looking statements to reflect the occurrence of anticipated or unanticipated events or circumstances after the date of such statements.

PART I

Item 1. Business

The response is incorporated herein by reference from the discussion respectively under the captions entitled “FINANCIAL HIGHLIGHTS” on page 4, “BUSINESS” on pages 5 through 7, “MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS” on pages 8 through 21 and Consolidated Financial Statements and Notes to Consolidated Financial Statements on pages 24 through 46 of the 2004 Annual Report.

Item 2. Properties

The Company conducts its business at its Corporate offices in North Andover and multiple branch locations listed here. The Company believes that all of its properties are well maintained and are suitable for banking needs and operations. Rent expense for 2004 totaled $186,000. The following table sets forth the locations of the offices of the Lawrence Savings Bank (the “Bank”), the wholly owned bank subsidiary of the Company, as well as certain information relating to these offices as of December 31, 2004:

Item 3. Legal Proceedings

     The Bank is involved in various legal proceedings incidental to its business. After review with legal counsel, management does not believe resolution of such litigation will have a material adverse effect on the financial condition and operating results of the Company.

     In one litigation matter, the Bank was awarded a $4.2 million judgment against the debtor in 1997. On February 13, 2002, the debtor filed a petition in bankruptcy under Chapter 7 of the Bankruptcy Code. Post-judgment interest calculated from the date of judgment to the date of the bankruptcy filing is approximately $1.9 million.

     On June 15, 2004 , the Company reported the receipt of $2.5 million on a U.S. Bankruptcy Judge’s Order on the Trustee’s Motion for authorization to make an interim distribution in this case in which the Company’s wholly owned subsidiary, Lawrence Savings Bank (the “Bank”), is the only secured creditor. The $2.5 million distribution was recorded as income by the Bank on June 15, 2004. The Bank has agreed to return any of the interim distribution as would be necessary to pay additional taxes imposed on the bankruptcy estate in the event reserves set aside for expenses and taxes are insufficient.

     The Bankruptcy Trustee has sold various assets during 2004 and 2005, and is currently holding approximately $1.8 million in cash (net of various expenses). The date of completion of the final tax returns for the Bankruptcy Estate (which

may create a recovery on taxes previously paid) and the distribution date of any remaining assets held by the Bankruptcy Trustee are not known at this time. Accordingly, no recognition of any of the remaining assets currently held by the Bankruptcy Trustee has been recorded in the Consolidated Financial Statements.

It is management’s opinion that the amount of and timing of any collection of any remaining amounts owed to the Bank beyond the amount of the interim distribution already received is substantially uncertain and not susceptible to meaningful estimation at this time.

Item 4. Submission of Matters to a Vote of Security Holders

     There were no matters submitted to a vote of the Company’s security holders during the fourth quarter of 2004.

Item 9A. Controls and Procedures

     The Company’s chief executive officer and chief financial officer, after evaluating the effectiveness of the Company’s “disclosure controls and procedures” (as defined in the Securities Exchange Act of 1934 Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this report, have concluded that the Company’s disclosure controls and procedures were effective to ensure that material information relating to the Company and its subsidiary required to be included in the Company’s periodic Securities and Exchange Commission filings would be made known to them by others within those entities in time to be included in the Company’s periodic Securities and Exchange Commission filings.

     There were no significant changes in the Company’s internal controls or, to the Company’s knowledge, in other factors that could significantly affect the Company’s disclosure controls and procedures during the last fiscal quarter that have materially affected, or are reasonable likely to materially affect the internal controls over financial reporting.
