OTHER INFORMATION Item 2. Changes in Securities and Use of Proceeds REINCORPORATION IN DELAWARE On March 12, 1998, Aspen Technology, Inc. a Massachusetts corporation ("Aspen Massachusetts"), changed its state of incorporation from Massachusetts to Delaware by merging with and into Aspen Technology, Inc., a Delaware corporation and a wholly owned subsidiary of Aspen Massachusetts ("Aspen Delaware" or the "Company"). As a result of the reincorporation, each outstanding share of Common Stock, $.10 par value per share, of Aspen Massachusetts ("Aspen Massachusetts Common Stock"), including each associated right under the Rights Agreement (the "Massachusetts Rights Plan") dated as of October 9, 1997 between Aspen Massachusetts and American Stock Transfer and Trust Company, as Rights Agent, changed and converted into one fully paid and non-assessable share of Common Stock, $.10 par value per share, of Aspen Delaware ("Aspen Delaware Common Stock"). In the reincorporation, the Certificate of Incorporation and By-Laws of Aspen Delaware, which were filed as Exhibits 3.1 and 3.2, respectively, to the Company's Current Report on Form 8-K dated March 26, 1998, became the constituent instruments defining the rights of holders of Aspen Delaware Common Stock following the reincorporation. The Company has previously reported, as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended ("Rule 12b-2"), the general effect of the material modifications to the rights of holders of Aspen Massachusetts Common Stock effected by the adoption of the Certificate of Incorporation and By-Laws of Aspen Delaware in its Proxy Statement dated as of November 25, 1997 under the heading "II. Proposal Two--Change in the State of Incorporation from Massachusetts to Delaware--Significant Changes Caused by the Reincorporation." Accordingly, the Company is not making an additional report of that information in this Form 10-Q. For additional information regarding changes in the Certificate of Incorporation of the Company, see "--Stockholder Rights Plan." STOCKHOLDER RIGHTS PLAN As a result of the reincorporation, each right outstanding under the Massachusetts Rights Plan, together with its associated share of Aspen Massachusetts Common Stock, was changed and converted into one share of Aspen Delaware Common Stock. In connection with the reincorporation, on March 12, 1998 the Board of Directors of the Company also issued rights (the "Delaware Rights") substantially equivalent to the rights previously outstanding under the Massachusetts Rights Plan. The Delaware Rights expire on March 12, 2008 unless earlier redeemed by the Company. The description and other terms of the Delaware Rights are set forth in a Rights Agreement (the "Delaware Rights Plan") dated as of March 12, 1998 between the Company and American Stock Transfer and Trust Company, as Rights Agent, filed as Exhibit 4.1 to the Company's Current Report on Form 8-K dated as of March 26, 1998 (including the Form of Certificate of Designation of Series A Participating Cumulative 3 Preferred Stock and the Form of Rights Certificate). In connection with the adoption of the Delaware Rights Plan, the Company amended its Certificate of Incorporation on March 12, 1998 by filing a Certificate of Designation with respect to the Series A Participating Cumulative Preferred Stock issuable upon exercise of the Delaware Rights. The Delaware Rights have certain antitakeover effects and could be deemed to materially limit or qualify the rights of holders of Aspen Delaware Common Stock. The Company has previously reported, as defined in Rule 12b-2, the general effect of the adoption of the Certificate of Designation and the issuance of the Delaware Rights upon the rights of the holders of Aspen Delaware Common Stock under the heading "Item 5. Other Events" in its Current Report on Form 8-K dated as of March 26, 1998. Accordingly, the Company is not making an additional report of that information in this Form 10-Q.
