</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">On March&nbsp;30, 2010, the Issuer filed a Form&nbsp;15 with the U.S. Securities and Exchange Commission (the
&#147;SEC&#148;) to (i)&nbsp;terminate the registration of its securities under Section 12(g) of the Securities
Exchange Act of 1934, as amended (the &#147;Exchange Act&#148;), and (ii)&nbsp;suspend its duty to file reports
under Sections&nbsp;13 and 15(d) of the Exchange Act. In connection with this filing, on March&nbsp;30,
2010, the Issuer entered into a Standstill and Protective Measures Agreement with Fund IV and Fund
IV Coinvest (the &#147;Agreement&#148;).
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Pursuant to the Agreement, until December&nbsp;31, 2010 (and subject to certain limitations), neither
Fund IV or Fund IV Coinvest nor any of their affiliates will, directly or indirectly, or otherwise
participate in, (a)&nbsp;any acquisition of any shares of Common Stock or common stock of any of the
Issuer&#146;s subsidiaries, including through any tender offer or similar mechanism or (b)&nbsp;any
transaction that would have the effect of the acquisition of such common stock, including for
example a cash out merger or other business combination or a reverse stock split by the Issuer;
provided, however, the foregoing limitations shall not apply if (i)&nbsp;notice of such proposed
transaction is provided to the Issuer by Fund IV, Fund IV Coinvest or any of their affiliates, (ii)
such proposed transaction would not result in Fund IV, Fund IV Coinvest and/or their Affiliates
owning 90% or more of the Issuer&#146;s then outstanding shares of capital stock on a fully diluted
basis (excluding the Common Stock which may be issued pursuant to certain convertible securities of
the Issuer held by Fund IV and Fund IV Coinvest), and (iii)&nbsp;with respect to an acquisition under
clause (a)&nbsp;above only, such acquisition is the result of an unsolicited offer made by a stockholder
of the Issuer to sell its shares of Common Stock to one or more of Fund IV, Fund IV Coinvest or any
of their affiliates.

the Issuer (the &#147;Board&#148;) determines in good faith is necessary to (A)&nbsp;avoid a pending or

related to a critical project of the Issuer or any of its subsidiaries, (ii)&nbsp;any transaction, such
as a cash out merger or reverse split, that the Board determines in good faith is necessary to
avoid the potential that the Issuer may revive its reporting obligations under Section&nbsp;13 or
Section 15(d) of the Exchange Act based on the number of its stockholders of record of Common
Stock, warrants or units to purchase common stock and warrants, (iii)&nbsp;any acquisition of Common
Stock by Fund IV or Fund IV Coinvest as a result of the conversion of any securities of the Issuer
held as of the date of the Agreement or (iv)&nbsp;any acquisition effected with the approval of a

<DIV align="center" style="font-size: 10pt; margin-top: 10pt"><B>ARGYLE SECURITY, INC. ANNOUNCES DEREGISTRATION OF COMMON STOCK,<BR>
WARRANTS AND UNITS</B>
</DIV>



<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">SAN ANTONIO, March&nbsp;30, 2010 /PRNewswire via COMTEX/ &#151; Argyle Security, Inc., (OTC Bulletin Board:
ARGL) (the &#147;Company&#148;), a service and solutions provider in the physical and electronic security
industry, announced that it has voluntarily deregistered its common stock, warrants and units
consisting of common stock and warrants and suspended its reporting obligations under the federal
securities laws by filing today a Form&nbsp;15 with the Securities and Exchange Commission (&#147;SEC&#148;). The
Company is eligible to deregister these securities because it has fewer than 300 holders of record
of each class of these securities.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Upon the filing of the Form&nbsp;15, the Company&#146;s obligation to file certain reports with the SEC,
including Forms 10-K, 10-Q and 8-K, will be suspended immediately, and deregistration of the
securities is expected to be effective within 90&nbsp;days after the filing of the Form&nbsp;15.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">The Company is taking these actions consistent with its heightened focus on cash management and
cost and expense containment initiatives stemming from its 2009 financial results that it plans to
submit to the OTC Disclosure and News Service not later than mid April&nbsp;2010 as described below.
Deregistration is expected to reduce significant financial and administrative burdens associated
with being a SEC reporting company and related regulatory compliance under the Sarbanes-Oxley Act
of 2002 (&#147;SOX&#148;), including under Section&nbsp;404 of SOX that is currently scheduled to be applicable to
the Company this year. As a result of deregistration of its securities, the Company will not
conduct the proposed rights offering to purchase shares of its common stock as previously reported
by the Company. In addition, the Company has no current plans to conduct any other &#147;qualified
equity offering&#148; as previously described and reported by the Company in connection with its
December&nbsp;2009 refinancing transactions.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">In connection with the Company&#146;s decision to deregister its securities, the Company and its
independent director negotiated a limited standstill agreement through the end of 2010, subject to
certain exceptions, with the Company&#146;s largest stockholder. In addition, the Company agreed to
provide annual and quarterly financial statements through the OTC Disclosure and News Service at
least through its 2010 annual financial statements. The Company plans to submit its audited
financial statements for the year ended December&nbsp;31, 2009 for dissemination on the OTC Disclosure
and News Service not later than mid April&nbsp;2010. Due to its prior SEC reporting and the reporting
of its annual and quarterly financial statements through the OTC Disclosure and News Service, the
Company anticipates that its common stock, units and warrants will continue to be eligible to be
quoted on the Pink Sheets in the near term, however, there can be no assurances that any broker
will make a market in the Company&#146;s common stock or other securities.
</DIV>

<DIV align="justify" style="font-size: 10pt; margin-top: 10pt">Sam Youngblood, the President and Chief Executive Officer of the Company, commented: &#147;After careful
consideration, the Company took this action because we believe that the costs associated with being
a SEC reporting company significantly outweigh the benefits to the Company and our stakeholders,
particularly in light of the Company&#146;s size, small market capitalization and thin trading of our
securities.&#148;
