ITEM 3.02.        UNREGISTERED SALES OF EQUITY SECURITIES.

         On March 30,  2005,  pursuant to the filing of an Amended and  Restated
Agreement and Plan of Merger,  Patron Systems,  Inc.'s (the "Registrant") merger
with Entelagent Software Corp.  ("Entelagent") became effective. The Amended and
Restated  Agreement  and Plan of Merger  amended and restated the  Agreement and
Plan of Merger  entered into by the parties on November 24, 2002. The merger was
consummated pursuant to a definitive Amended and Restated Supplemental Agreement
entered into as of February 24, 2005, and the Amended and Restated Agreement and
Plan of Merger, each among the Registrant, ESC Acquisition, Inc., a wholly-owned
subsidiary  of the  Registrant  and  Entelagent.  Pursuant  to the  terms of the
Amended  and  Restated  Supplemental  Agreement  and the  Amended  and  Restated
Agreement and Plan of Merger with Entelagent, ESC Acquisition,  Inc. merged with
and into  Entelagent,  with  Entelagent  surviving the merger as a  wholly-owned
subsidiary of the  Registrant.  In connection  with the Entelagent  merger,  the
Registrant  issued  3,000,000  shares  of  Common  Stock  in  exchange  for  the
outstanding shares of the capital stock of Entelagent.

         The  Registrant  has agreed to  register  the  resale of the  3,000,000
shares of Common Stock issuable to the holders of the outstanding  capital stock
of Entelagent at such time as the Registrant next files a registration statement
with the Securities and Exchange Commission  ("SEC").  In addition,  pursuant to
the terms of the Amended and Restated  Supplemental  Agreement,  the  Registrant
will also (i) issue to certain officers,  directors,  shareholders and creditors
of Entelagent,  in  consideration of amounts owed by Entelagent to such parties,
promissory notes in the aggregate principal amount of approximately  $2,640,000,
with interest payable thereon at a rate of 8% per annum and maturing on February
28, 2006, and (ii) repay approximately  $1,351,000 in outstanding liabilities of
Entelagent.

         The  issuance  and  sale  of  the  securities  issued  or  issuable  in
connection  with the  Entelagent  merger were exempt from the  registration  and
prospectus delivery  requirements of the Securities Act of 1933, as amended (the
"Securities Act") pursuant to Section 4(2) of the Securities Act as transactions
not involving any public offering.

         The press release  announcing this  transaction is furnished as Exhibit
99.1 to this report and is incorporated herein by reference.
