ITEM 1.01         ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.
ITEM 3.02.        UNREGISTERED SALES OF EQUITY SECURITIES.
ITEM 5.03.        AMENDMENTS TO ARTICLES OF INCORPORATION  OR BYLAWS;  CHANGE IN
                  FISCAL YEAR.

         On October 11, 2006,  Patron Systems,  Inc. (the  "Registrant"),  filed
with  the  Delaware   Secretary  of  State  a  Certificate   of  Designation  of
Preferences,  Rights and Limitations of Series B Convertible  Preferred Stock of
Patron Systems,  Inc.  ("Certificate  of  Designation"),  designating the rights
preferences  and  privileges of 2,000 shares of Series B  Convertible  Preferred
Stock.

         The Series B Convertible  Preferred Stock ("Series B Preferred  Stock")
has a stated  value of $5,000  per share,  has no  maturity  date and  carries a
dividend of 10% per annum, with such dividend accruing on a cumulative basis and
payable  only (i) at such time as declared  payable by the Board of Directors of
the Registrant or (ii) in the event of  liquidation,  as part of the liquidation
preference  amount for the Series B  Preferred  Stock  ("Liquidation  Preference
Amount").  The Liquidation Preference Amount is equal to 125% of the sum of: (i)
the stated value of any then unconverted  shares of Series B Preferred Stock and
(ii) any accrued and unpaid dividends thereon. An event of liquidation means any
liquidation,  dissolution or winding up of the Registrant,  whether voluntary or
involuntary,  as well as any  change of control of the  Registrant  which  shall
include the sale by the Registrant of either (x) substantially all its assets or
(y) the portion of its assets  which  comprises  its core  business  technology,
products  or  services.  The Series B  Preferred  Stock is junior in rank to the
Registrant's  Series A Convertible  Preferred  Stock with respect to liquidation
and dividend rights.

         The  Series B  Preferred  Stock is  convertible,  at the  option of the
holder,  into  shares of the common  stock,  par value  $0.01 per share,  of the
Registrant  ("Common Stock") at an initial  conversion price of the lesser of i)
$2.40 per share or ii) that price per share equal to the volume weighted average
closing price of the Company's common stock for the 10 trading days prior to the
original issuance date of such shares, based on the stated value of the Series B
Preferred   Stock,   subject  to  adjustment   for  stock   splits,   dividends,
recapitalizations,  reclassifications, payments made to Common Stock holders and
other similar  events and for issuances of additional  securities at prices more
favorable than the active price at the date of the adjustment.

         The Series B Preferred Stock automatically  converts into Common Stock,
at the then applicable  conversion price based on the stated value of the Series
B  Preferred  Stock,  on  the  date  that:  (i)  there  shall  be  an  effective
registration  statement  covering the resale of the Common Stock  issuable  upon
conversion of the Series B Preferred  Stock,  (ii) the average  closing price of
the Common Stock for a period of 20 consecutive trading days is at least 250% of
the then applicable conversion price, and (iii) the average daily trading volume
of the Common Stock for the same period is at least 8,334 shares.

         The Series B Preferred Stock, on an as-converted  basis,  vote with the
Common Stock on all matters  requiring  stockholder  approval.  Additionally,  a
majority  of the  outstanding  Series B  Preferred  Stock,  voting as a separate
class,  is required for any amendment to the  Certificate  of  Designation,  the
Registrant's  certificate of incorporation or bylaws which would directly and/or
indirectly amend, alter, change, repeal or otherwise adversely affect any of the
powers, designations, preferences and rights of the Series B Preferred Stock, as
applicable,  including  to  create,  authorize  or issue any series or shares of
senior  stock or parity stock or to increase  the amount of  authorized  capital
stock of any such  class.  For so long as the Series B  Preferred  Stock  remain
outstanding,  the approval of a majority of the issued and outstanding shares of
Series B Preferred  Stock is required for the  Registrant  to issue funded debt,
other  than  $1,000,000  of  working  capital  advances  from one or more of its
existing  investors,  and to issue any  preferred  stock senior to or pari passu
with the Series B Preferred Stock.


                                       2



         On  October  13,  2006,  pursuant  to  the  execution  of  subscription
agreements on October 12, 2006, the Registrant  completed the first closing of a
financing (the "Series B Financing")  in the amount of  $3,120,966,  through the
issuance  of  units,  at a  purchase  price of  $100,000  per  unit,  each  unit
consisting  of (i) 20 shares of Series B Preferred  Stock and (ii) Common  Stock
Purchase  Warrants  ("Warrants")  to  purchase up to 50% of the shares of Common
Stock  issuable upon the  conversion  of the shares of Series B Preferred  Stock
purchased  ("Units").  The Registrant  issued 624.2 shares of Series B Preferred
Stock  (convertible  into  1,387,992  shares of Common  Stock) and  Warrants  to
purchase 694,011 shares of Common Stock to the investors in the first closing of
the Series B  Financing.  The  Warrants  have a term of 5 years and an  exercise
price of the lesser of i) $2.40 per share or ii) that  price per share  equal to
the volume weighted average closing price of the Common Stock for the 10 trading
days prior to the original  issuance date of the  applicable  shares of Series B
Preferred Stock, based on the stated value of the Series B Preferred, subject to
adjustment for stock splits,  dividends,  recapitalizations,  reclassifications,
payments made to Common Stock holders and other similar events and for issuances
of additional  securities at prices more favorable than the conversion  price at
the date of such issuance. The Registrant has agreed to file with the Securities
and  Exchange  Commission,  no  later  than 90 days  after  the  closing  date a
registration  statement  for the resale of the shares of Common  Stock  issuable
upon exercise of the Warrants and conversion of the Series B Preferred Stock.

         The  aggregate  proceeds in the first closing of the Series B Financing
were  comprised  of  $1,040,322  provided by Apex  Investment  Fund V, L.P.  and
$2,080,644 from forty-five  accredited investors introduced by Laidlaw & Company
(UK) Ltd. ("Laidlaw").

         Laidlaw  acted as placement  agent in the Series B  Financing.  For its
services as placement  agent, in connection with the first closing of the Series
B Financing,  the  Registrant  paid Laidlaw a cash fee of $280,484 and issued to
Laidlaw warrants to purchase up to 208,198 shares of Common Stock at an exercise
price of the lesser of i) $2.40 per share or ii) that  price per share  equal to
the volume weighted average closing price of the Common Stock for the 10 trading
days prior to the original  issuance date of the  applicable  shares of Series B
Preferred  Stock,  based on the stated  value of the Series B  Preferred  Stock,
subject  to   adjustment   for  stock  splits,   dividends,   recapitalizations,
reclassifications,  payments  made to Common  Stock  holders  and other  similar
events and for issuances of additional  securities at prices more favorable than
the conversion price at the date of such issuance.  The Registrant has agreed to
file with the  Securities and Exchange  Commission,  no later than 90 days after
the closing date a registration statement for the resale of the shares of Common
Stock issuable upon exercise of the Warrants issued to Laidlaw.

         The  issuance  and  sale  of  the  securities  issued  or  issuable  in
connection with the first closing of the Series B Financing were exempt from the
registration and prospectus delivery requirements of the Securities Act of 1933,
as amended (the "Securities Act") pursuant to Rule 506 promulgated under Section
4(2) of the Securities Act.
