Item 5.  Other Events.

         On February 2, 1998, BMC Software, Inc., a Delaware corporation
("BMC"), issued a press release announcing the execution of a definitive merger
agreement dated January 31, 1998,  providing for the acquisition of BGS
Systems, Inc., a Massachusetts corporation ("BGS"), by BMC in a transaction
valued at approximately $285 million.  BMC will pay the equivalent of $45 in
BMC common stock for each share of BGS common stock, using the average price
per share of BMC common stock during a ten day trading period preceding the
closing.  The transaction is expected to close within 60 to 90 days, subject to
BGS stockholder approval, regulatory approval and other customary closing
conditions.

         The foregoing summary is subject to the full text of the press release
with respect thereto, a copy of which is attached hereto as Exhibit 99.1 and is
incorporated herein by reference.

         A registration statement relating to BMC's common stock has not yet
been filed with the Securities and Exchange Commission (the "SEC"), nor has a
proxy statement relating to the vote of BGS's stockholders on the merger been
filed with the SEC.  BMC's common stock may not be offered, nor may offers to
acquire such stock be accepted, prior to the time such registration statement
becomes effective.  This report shall not constitute an offer to sell or the
solicitation of any offer to buy any of BMC's common stock or any other
security, and shall not constitute the solicitation of any vote with respect to
the merger.
