Item 1.01 Entry Into A Material Definitive Agreement
     On March 12, 2009, the Board of Directors of American Shared Hospital Services (the “Company”) approved the First Amendment (the “Amendment”) to its existing shareholder rights plan dated as of March 22, 1999, between the Company and American Stock Transfer & Trust Company (the “Rights Agreement”). The Amendment extends the final expiration date on which the Rights (as defined in the Rights Agreement) are exercisable until the close of business on April 1, 2019. The Amendment also provides that each Right will entitle the holder thereof to purchase from the Company one-tenth of a share of the Company’s common stock, no par value, at an initial exercise price of $0.950. The foregoing description of the terms of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment attached hereto and incorporated by reference and to the Rights Agreement.
     The Board of Directors desires to maintain for shareholders the benefits of the existing rights plan. The purpose of the plan is to discourage the use of coercive takeover tactics against the Company and to permit the Board, in the event of an acquisition proposal, to negotiate a fair and adequate price and terms that are in the best interest of shareholders. The Amendment was adopted because the existing rights plan is scheduled to expire in less than one month. The Company is not aware of an actual or threatened hostile acquisition proposal except as described in the next succeeding paragraph.
     During the past eighteen months, the Company has discussed from time to time with two different parties the possible sale of its 81% interest in GK Financing LLC (“GKF”). One of the parties has conducted an extensive due diligence review of GKF’s business, but has not to date been willing to enter into a definitive purchase agreement on terms that are satisfactory to the Company. In September 2008, this party made a non-binding, conditional “proposal” to acquire the Company for $3.85 per share, a price which was subsequently lowered without explanation on December 2, 2008 to $2.30 per share. The Company believes that this proposal, which the party threatened to “publicly announce,” was primarily an attempt to coerce the Company to accept a transaction for GKF that would not be favorable to shareholders. The Company responded that it would continue to explore a sale of GKF on appropriate terms but that the Board did not consider the proposed price for the Company, which is less than net book value and only slightly in excess of cash on hand, to be adequate. In addition, the Board was unwilling to enter into a transaction that would deprive the shareholders of the future value of the non-Gamma Knife business. The parties thereafter conducted additional negotiations regarding a possible sale of the Company’s interest in GKF, but again have failed to reach a satisfactory conclusion. The Company cannot predict whether negotiations will resume or whether an agreement that is acceptable to the Company for the sale of its interest in GKF will be achieved.
Item 2.02 Results of Operations and Financial Conditions
     On March 13, 2009, the Company issued a press release announcing its financial results for the three and twelve months ended December 31, 2008. The full text of the press release is furnished as Exhibit 99.1 to this report. The Company does not intend for this exhibit to be incorporated by reference into future filings under the Securities Exchange Act of 1934.
Item 3.03 Modification to Rights of Security Holders
     As indicated in the response to Item 1.01 of this Form 8-K, the Company and American Stock Transfer & Trust Company, as Rights Agent, have executed the Amendment, which amends the Company’s Rights Agreement. The Amendment modifies certain rights of holders of the Rights issued under the Rights Agreement and registered pursuant to Section 12(b) of the Securities Exchange Act of
