  Item 1.01  Entry into a Material Definitive Agreement.
  On
  April 22, 2008, Argyle Security, Inc. (the "
  Company
  ")
  entered into a Securities Purchase Agreement (the "
  Purchase
  Agreement
  ") with Mezzanine Management Fund IV A and Mezzanine
  Management Fund IV Coinvest A (the "
  Purchasers
  "),
  and Sam Youngblood, Ron Chaimovski and Bob Marbut (together, with their
  affiliates, the "
  Stockholders
  "), pursuant to
  which the Purchasers purchased 18,750 shares of a newly created series of our
  preferred stock, designated "Series A Convertible Preferred Stock", par
  value $0.0001 per share (the "
  Series A Preferred
  Shares
  ") for an aggregate purchase price of $15,000,000 (the "
  Series A Financing
  ").
  The
  Series A Preferred Shares have no voting rights, except as required by
  law.
  Each
  Series A Preferred Share is convertible into the Company's common stock,
  $0.0001 par value ("
  Common Stock
  "), at any time,
  at the option of the holder, initially at a conversion price of $8.00 per share
  of Common Stock, subject to adjustment for stock dividends, stock splits or
  similar capital reorganizations, and weighted average price protection for
  certain issuances below the conversion price.
  The
  holders of the Series A Preferred Shares shall be entitled to receive, on
  a cumulative basis, cash dividends, when, as and if declared by the Company's
  Board of Directors, at the greater of (i) 3% per annum or (ii) the
  dividend payable on the equivalent amount of Common Stock into which the Series A
  Preferred Shares could be converted; provided, however, that such cash dividend
  must be paid at the earliest any of the following occur:  (A) the Company pays a dividend on the
  Common Stock, (B) the Company liquidates or there is a change in control,
  or (C) upon conversion of the Series A Preferred Shares, but only
  with respect to those Series A Preferred Shares so converted.
  The
  Series A Preferred Shares have a liquidation preference to the Common
  Stock equal to the greater of (i) the sum of the original issue price
  (subject to adjustment for stock dividends, stock splits or similar capital
  reorganizations) plus all accrued but unpaid dividends, or (ii) the amount
  the holder would receive if all Series A Preferred Shares had been
  converted into Common Stock.
  For
  as long as any shares of Series A Preferred Shares remain outstanding, the
  Company will be prohibited from (i) amending, waiving, altering or
  repealing in a way that adversely affects the rights, powers, preferences, or
  other special rights or privileges of the holders of the Series A
  Preferred Shares, whether by amendment to the Certificate of Incorporation,
  Bylaws, Certificate of Designation or other organization documents, or by
  merger, consolidation, reorganization or otherwise, (ii) increasing or
  decreasing (other than by redemption or conversion) the authorized number of
  shares of preferred stock or Series A Preferred Shares, or (iii) repurchasing,
  redeeming or reissuing any equity securities of the Company to which the Series A
  Preferred Shares rank senior and prior (whether with respect to dividends,
  redemption, or upon liquidation or otherwise), including the Common Stock, and
  any rights or options exercisable or convertible therefor, other than
  repurchases of shares of Common Stock from employees, officers, directors or
  consultants under agreements providing for such repurchase under certain conditions.
  Under the Purchase Agreement, the Company has agreed to use reasonable best efforts to effect a registration under the Securities Act of 1933 covering the resale of the shares of Company Common Stock issuable upon conversion of the Series A Preferred Shares; provided that (i) the request is made by holders of Series A Preferred Shares representing not less than 50% of the shares of Common Stock issuable upon conversion of the Series A Preferred Shares, and (ii) only two such requests can be made, in the aggregate, by the Purchasers.  The Company also granted piggyback registration rights to the Purchasers.
  The Company has granted a preemptive right to the Purchasers with respect to future financings by the Company and a right of first offer to provide financing for certain transactions.

  The Company intends to use the net proceeds of the Series A Financing for working capital and general corporate purposes.  The Company has paid a one percent commitment fee paid to the Purchasers, and will reimburse the Purchasers' transaction-related expenses and pay a fee of $900,000 to the placement agent, Rodman & Renshaw, LLC.
  The Series A Preferred Shares have not been registered under the Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirement.
  The information set forth above is qualified in its entirety by reference to the actual terms of the Certificate of Designations and the Purchase Agreement attached hereto as Exhibits 3.1 and 10.1 and which are incorporated herein by reference.
