WHEREAS, the Company and the Rights Agent previously entered into that certain Rights Agreement, dated as of July 29, 1999 (the “Rights Agreement”);

WHEREAS, the Company proposes to enter into a Share Purchase Agreement (as it may be amended from time to time, the “Purchase Agreement”), with Great Wall Technology Company Limited, a PRC company (“GWT”), ExcelStor Group Limited, a Cayman Islands company (“ExcelStor Group”), ExcelStor Holdings Limited, a British Virgin Islands company (“ExcelStor Holdings” and together with GWT and ExcelStor Group, “Selling Shareholders” and each individually, a “Selling Shareholder”), ExcelStor Great Wall Technology Limited, a Cayman Islands company (“ESGWT”), Shenzhen ExcelStor Technology Limited, a PRC company (“SETL” and together with ESGWT, the “Top Level Operating Companies” and each individually, a “Top Level Operating Company”), providing for the sale (the “Sale”) of 100% of the issued and outstanding shares of the Top Level Operating Companies by the Selling Shareholders to the Company in exchange for that number shares of the Company’s common stock, par value $0.03-1/3 per share, as is equal to approximately 60% of the issued and outstanding capital stock of the Company immediately following the consummation of the Sale (utilizing the treasury stock method for the purpose of calculating stock options);

WHEREAS, the Board of Directors of the Company has determined that, in connection with the execution of the Purchase Agreement, it is necessary and desirable to amend the Rights Agreement to exempt, among other things, the Purchase Agreement, the execution thereof and the transactions contemplated thereby, including, without limitation, the Sale, from the application of the Rights Agreement, in each case as set forth in this Amendment;
