Amendment No. 9 to Schedule 13D

This Amendment No. 9 to Schedule 13D (this “Ninth Amendment”) amends and supplements the Schedule 13D originally filed on May 5, 2008, as amended by Amendment No. 1 filed on January 15, 2009, Amendment No. 2 filed on May 20, 2009, Amendment No. 3 filed on June 2, 2009, Amendment No. 4 filed on June 5, 2009, Amendment No. 5 filed on June 11, 2009, Amendment No. 6 filed on June 16, 2009, Amendment No. 7 filed on August 5, 2009 and Amendment No. 8 filed on October 1, 2009 (together, the “Schedule 13D”), and relates to the common stock, par value $0.0001 (the “Common Stock”), of Argyle Security, Inc., a Delaware corporation (the “Issuer”). This Ninth Amendment is being filed by and on behalf of Mezzanine Management Fund IV A, L.P., a limited partnership organized under the laws of the United Kingdom (“Fund IV”), Mezzanine Management Fund IV Coinvest A, L.P., a limited partnership organized under the laws of the United Kingdom (“Fund IV Coinvest”), and Mezzanine Management Limited, a limited partnership organized under the laws of Bermuda (“Mezzanine”). Fund IV, Fund IV Coinvest, and Mezzanine are collectively referred to herein as the “Reporting Persons.”


Item 4.		Purpose of the Transaction.

Paragraphs (a), (d) and (j) of Item 4 of the Schedule 13D are hereby amended and supplemented, with effect from the date of this Ninth Amendment, as follows:

On December 14, 2009, the Issuer, in exchange for cash, issued to each of Fund IV and Fund IV Coinvest convertible bridge notes (the “MML Bridge Notes”) in an aggregate principal amount of $8.0 million and convertible subordinated promissory notes in the aggregate principal amount of $2.45 million (the “MML Convertible Notes”), with each of these notes bearing interest at 10% per annum. On each interest payment date, accrued but unpaid interest on the MML Bridge Notes is capitalized and added to the principal balance thereof.

Under the MML Bridge Notes, the Issuer has agreed to use its commercially reasonable efforts to complete a rights offering of Common Stock to its existing common stockholders as promptly as reasonably practicable. The proceeds from such rights offering received from stockholders, other than Fund IV and Fund IV Coinvest, will be used to repay the MML Bridge Notes. Any portion of the MML Bridge Notes not repaid or otherwise used by Fund IV or Fund IV Coinvest to subscribe for shares of Common Stock in such rights offering (or other Issuer equity offering for cash) will automatically be converted into such Common Stock as of the earlier of (1) the closing of the rights offering (or such other Issuer equity offering) or (2) June 30, 2010, at a price per share equal to (A) the price per share offered in the rights offering (or such other Issuer equity offering) or (B) if no rights offering (or other Issuer equity offering) is consummated by June 30, 2010, $0.4302, which reflects the volume weighted average sale price for the Common Stock from trades quoted on the OTC Bulletin Board for the ten days ending on the day prior to the issuance of the MML Bridge Notes (the “VWAP Price”).

The MML Convertible Notes are convertible into shares of Common Stock, at the option of Fund IV and Fund IV Coinvest, at a price equal to (1) the price per share offered in the rights offering (or such other Issuer equity offering) if consummated on or prior to June 30, 2010, or (2) the VWAP Price if no such rights offering (or such other Issuer equity offering) is consummated by June 30, 2010.

CUSIP No.		040311102

The provisions of the Issuer’s outstanding preferred stock currently provide for customary weighted average anti-dilution protections based on the issuance of new securities at a price per share lower than (i) in the case of the Issuer’s outstanding Series A Convertible Preferred Stock (the “Series A Stock”), the then fair market value of the Common Stock and (ii) in the case of the Issuer’s outstanding Series B Convertible Preferred Stock (the “Series B Stock”), the greater of (A) the conversion price (currently $1.10 per share) or (B) the then fair market value of the Common Stock. The Issuer has obtained from the Reporting Persons, as the holder of all of the Issuer’s outstanding Series A Stock and Series B Stock, a waiver of any anti-dilution protections that may be triggered as a result of the original issuance of the MML Bridge Notes, the MML Convertible Notes and the Subordinated Interest Note (as defined below) (collectively, the “New Securities”) on December 14, 2009. For purposes of this Ninth Amendment, “Subordinated Interest Note” means that certain convertible subordinated promissory note dated December 14, 2009, issued by ISI Security Group, Inc., a subsidiary of the Issuer (“ISI”), in favor of ISI’s primary subordinated lender in the aggregate principal amount of approximately $897,000, which promissory note is convertible into Common Stock in generally the same manner as the MML Bridge Notes. Notwithstanding the foregoing, upon the ability of the holders of the New Securities to convert them into Common Stock, the anti-dilution protection provided to the holders of each of the Series A Stock and the Series B Stock will apply in full force and effect.

In addition, the Reporting Persons, as the holders of all of the Issuer’s outstanding Series A Stock and the Series B Stock, provided a waiver to the Issuer of the change of control liquidation event provided for under the terms of the Series A Stock and the Series B Stock to the extent the Reporting Persons (or their affiliates) may obtain such control as a result of the consummation of an equity offering by the Issuer on or prior to June 29, 2010, issuance or conversion of the New Securities, or the ability of the holders to convert the New Securities into Common Stock.

The foregoing description of the MML Bridge Notes and the MML Convertible Notes are qualified in their entirety by the actual terms of the form of MML Bridge Notes and MML Convertible Notes filed herewith as Exhibits B and C.


Item 6.		Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 of the Schedule 13D is hereby amended and supplemented, with effect from the date of this Ninth Amendment, as follows:

See the discussion of the MML Bridge Notes and the MML Convertible Notes in Item 4 above.


Item 7.		Material to be Filed as Exhibits.

Item 7 of the Schedule 13D is hereby amended and supplemented, with effect from the date of this Ninth Amendment, as follows:

Exhibit B — Form of 10% Convertible Subordinated Bridge Promissory Note from the Issuer, as debtor.

(a) Interest Rate. Subject to Section 3(b), the outstanding principal amount of this Note shall bear interest, for each day from the date of this Note until its principal amount is paid in full, at a rate per annum equal to 10%.

(b) Default Rate of Interest. After the occurrence and during the continuance of an Event of Default, the unpaid principal amount of this Note outstanding from time to time shall bear interest at a rate per annum equal to 12%.

(c) Payment of Interest. Interest will be payable in arrears on the last day of each quarter and on the Maturity Date, commencing on March 31, 2010 (each such date being referred to herein as an “Interest Payment Date”). All interest shall be computed on the basis of a 360-day year and paid for the actual number of days elapsed. Notwithstanding any provision in this Note to the contrary, in lieu of paying in cash for interest accrued to any Interest Payment Date, accrued but unpaid interest shall be capitalized and added as of such Interest Payment Date to the outstanding principal amount of this Note (the amount so capitalized, the “PIK Interest”). The PIK Interest shall bear interest from the applicable Interest Payment Date at the same rate per annum as the original principal amount of this Note and be payable in the same manner as the original principal amount of this Note and shall otherwise be treated as principal of this Note for all purposes. From and after each Interest Payment Date, the principal amount of this Note shall, without further action on the part of Debtor or Purchaser, be deemed to be increased by the PIK Interest so capitalized and added to principal in accordance with the provisions hereof.

4. Payment of Principal.

(a) Mandatory Payments. Subject to the conversion of this Note, in full or in part, in accordance with the provisions of Section 6 below, the outstanding principal amount of this Note shall be due and payable (i) in full after the occurrence of a Change of Control, subject to the payment in full of any amount due and payable to the Senior Creditors with respect to outstanding Senior Indebtedness that is required to be repaid as a result of such Change of Control, such payment to be made on the earlier of (x) thirty (30) days after the date such Change of Control occurs or (y) the date such Change of Control occurs if, on or before such date, the holder of this Note has waived its right to give notice of its election to convert this Note pursuant to Section 6(c) or (ii) upon the closing of the Qualified Equity Offering, to the extent of the Net Cash Proceeds.

(b) Voluntary Prepayments. Debtor may not prepay the principal amount of or interest on this Note in whole or in part. Nothing herein contained shall in any way restrict the ability of the holder of this Note to accept mandatory payments required to be made pursuant to Section 4(a), to participate in the Rights Offering as provided in Section 4(c) or convert the Note as herein provided.

(c) Satisfaction by Participation in Rights Offering. If Debtor makes the Rights Offering, the holder of this Note will purchase shares of Common Stock offered in the Rights Offering (including its basic subscription rights, its oversubscription rights and any backstop commitment) up to the full extent of the unpaid principal amount of the Note, together with any remaining accrued but unpaid interest, after the application of the Net Cash Proceeds, and the holder shall be entitled to satisfy its obligations under the Rights Offering by offsetting the amount owed by the holder with respect to its obligations under the Rights Offering against the amount owed to the holder under this Note. At the Closing of the Rights Offering, any amount not so satisfied pursuant to Section 4(a)(ii) or this Section 4(c) shall be converted as provided in Section 6(a).

5. Manner and Time of Payment.

(a) Payment in Same Day Funds. All payments by Debtor with respect to this Note shall be made in same day funds and delivered to Purchaser by wire transfer to such accounts as Purchaser may designate from time to time. Debtor shall receive credit for such funds on the date received if Purchaser receives such funds by 5:00 p.m. (New York City time) on such day. In the absence of timely receipt, such funds shall be deemed to have been paid by Debtor on the next succeeding Business Day.

(b) Payment on Non-Business Days. If any payment on this Note shall become due on a day that is not a Business Day, such payment shall be made on the next succeeding Business Day and such extension of time shall in such case be included in computing any interest due in connection with such payment.

6. Conversion of Note.

(a) Automatic Conversion upon a Qualified Equity Offering. If a Qualified Equity Offering is closed and funded during the QEO Period, the principal balance outstanding under this Note, together with any then accrued but unpaid interest, after application of mandatory prepayments of Net Cash Proceeds pursuant to Section 4(a)(ii) and Purchaser’s participation in the tender offer pursuant to Section 4(c) (the “Post-QEO Converted Amount”), shall automatically be converted into a number of fully paid and nonassessable shares of Common Stock equal to the quotient obtained by dividing (i) the Post-QEO Converted Amount by (ii) the QEO Conversion Price.

(b) Automatic Conversion at the Maturity Date. If no Qualified Equity Offering is consummated during the QEO Period, then on June 30, 2010, the unpaid principal balance outstanding under this Note, together with any then accrued and unpaid interest (the “Maturity Date Converted Amount”), shall automatically be converted into a number of fully paid and nonassessable shares of Common Stock equal to the quotient obtained by dividing (i) the Maturity Date Converted Amount by (ii) the Issuance Date Conversion Price, as the same may be adjusted pursuant to Section 7 hereof.

(c) Optional Conversion Upon Change of Control. Not less than thirty (30) days prior to consummation of any Change of Control (or, if such Change of Control occurs without the agreement or participation by Debtor, as soon as reasonably possible after Debtor obtains knowledge of the occurrence of such Change of Control or of any event, or the taking of any action, by any Person, that could reasonably be expected to cause, or result in, a Change of Control), Debtor shall give the holder of this Note written notice of such Change of Control, event or action, and the holder of this Note may at any time prior to the date thirty (30) days after such Change of Control is consummated, notify Debtor that it has elected to convert all or any portion of the principal balance outstanding under this Note, together with any then accrued and unpaid interest (the amount to be so converted, the “COC Conversion Amount”), whereupon the COC Conversion Amount shall automatically convert into fully paid and nonassessable shares of Common Stock on the date such notice is given by such holder. Any such notice by the holder may be conditioned upon the consummation of the Change of Control. The number of shares of Common Stock that the holder of this Note shall be entitled to receive upon such conversion pursuant to this Section 6(c) shall equal the quotient obtained by dividing (i) the total COC Conversion Amount by (ii) the Issuance Date Conversion Price, as the same may be adjusted pursuant to Section 7 hereof.

(d) Certain Procedures. The holder of this Note that is entitled to receive shares of Common Stock issuable upon conversion of this Note pursuant to Section 6(a), (b) or (c), as applicable, shall be deemed to have converted this Note as of (i) in the event of a conversion pursuant to Section 6(a), the time of the closing and funding of the Qualified Equity Offering during the QEO Period, (ii) in the event of a conversion pursuant to Section 6(b), June 30, 2010, and (iii) in the event of a conversion pursuant to Section 6(c), upon the giving of the holder’s notice of conversion pursuant to Section 6(c) (as applicable, the “Conversion Date”). As of the Conversion Date, the Post-QEO Converted Amount, the Maturity Date Converted Amount or the COC Conversion Amount, as applicable, shall be converted automatically without any further action by the holder and whether this Note is surrendered to Debtor at the QEO Conversion Price or the Issuance Date Conversion Price (as the same may be adjusted pursuant to Section 7 hereof), as applicable; provided, however, that Debtor shall not be obligated to issue certificates evidencing the shares of Common Stock issuable upon such conversion until this Note is either delivered to Debtor, as hereinafter provided, or the holder of this Note notifies Debtor, as hereinafter provided, that such Note have been lost, stolen or

destroyed and executes an agreement reasonably satisfactory to Debtor to indemnify Debtor from any loss incurred by it in connection therewith. Thereupon, there shall be issued and delivered to such holder, promptly at such office and in the name of such holder as shown hereon, a certificate or certificates for the number of shares of Common Stock into which the Note surrendered was convertible as of such Conversion Date, and with respect to partial conversions, a new note in the form of this Note for the remaining principal balance outstanding, together with accrued and unpaid interest, not so converted. Any person whose name the certificate for shares of Common Stock is to be issued shall be considered to have become a holder of record of such shares of Common Stock as of the closing of business on the applicable Conversion Date.

(e) No Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Post-QEO Converted Amount, the Maturity Date Converted Amount or the COC Conversion Amount, as applicable, and the number of shares of Common Stock to be issued upon such conversion shall be rounded down to the nearest whole share. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of the Post-QEO Converted Amount, the Maturity Date Converted Amount or the COC Conversion Amount, as applicable, Debtor shall pay a cash adjustment in respect of such fractional interest in an amount equal to the product of (i) the fractional amount, multiplied by, (ii) the QEO Conversion Price or the Issuance Date Conversion Price (as the same may be adjusted pursuant to Section 7 hereof), as applicable.

7. Adjustment to Issuance Date Conversion Price for Diluting Issues.

(a) Special Definitions. For purposes of this Section 7, the following definitions shall apply:

(i) “Additional Shares of Common” shall mean all shares of Common Stock issued (or, pursuant to Section 7(c), deemed to be issued) by Debtor after the Issuance Date, other than (1) shares of Common Stock issued or issuable to officers, directors, employees or consultants to Debtor or its Subsidiaries pursuant to a stock grant, stock option plan, stock purchase plan or other stock incentive agreement (collectively, the “Plans”) approved by the Board of Directors; (2) shares of Common Stock issued or issuable pursuant to exercise, conversion or exchange of options, warrants or Convertible Securities outstanding as of the Issuance Date, including the MML Bridge Notes, the MML Convertible Notes and the DI Promissory Note, (3) shares of Common Stock issued or issuable in connection with a business acquisition or combination approved by the Board of Directors, (4) shares of Common Stock or Convertible Securities issued or issuable in a Qualified Equity Offering, (5) shares of Common Stock issued or issuable for which an adjustment to the Issuance Date Conversion Price is made pursuant to Section 7(f), or (6) upon the written approval or consent of the holders of a majority of the then outstanding aggregate principal balance of the MML Bridge Notes.

(ii) “Convertible Securities” shall mean any evidences of indebtedness, shares (other than Common Stock) and all other securities convertible into or exchangeable for Additional Shares of Common.

(iii) “Market Price” shall mean the value that would be paid by a willing buyer to an unaffiliated willing seller in a transaction not involving distress or necessity of either party, determined in good faith by the Board of Directors.

(iv) “Options” shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire either Additional Shares of Common or Convertible Securities.

(b) No Adjustment of Issuance Date Conversion Price. No adjustment in the Issuance Date Conversion Price shall be made in respect of the issuance of Additional Shares of Common unless the consideration per share (determined pursuant to Section 7(a)(i) for an Additional Share of Common issued or deemed to be issued by Debtor is less than the Issuance Date Conversion Price, in effect on the date of, and immediately prior to, such issuance.

(i) Options and Convertible Securities. In the event Debtor at any time or from time to time after the Issuance Date and while any portion of this Note is outstanding shall issue any Options or Convertible Securities, other than Options or Convertible Securities exempted pursuant to Section 7(a)(i), or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number) of Common Stock issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date. Provided that Additional Shares of Common shall not be deemed to have been issued unless the consideration per share (determined pursuant to Section 7(e) hereof) of such Additional Shares of Common would be less than the Issuance Date Conversion Price in effect on the date of and immediately prior to such issue, or such record date, as the case may be, and provided further that in any such case in which Additional Shares of Common are deemed to be issued:

(1)

no further adjustment in the Issuance Date Conversion Price shall be made upon the subsequent issuance of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities;

	(2)		if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase or decrease in the consideration payable to Debtor, or increase or decrease in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, the Issuance Date Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease; provided, however, that no such adjustment of the Issuance Date Conversion Price shall affect Common Stock previously issued upon conversion of the Note;

	(3)		if any such Options or Convertible Securities shall expire without having been exercised or converted, the Issuance Date Conversion Price as adjusted upon the issuance of such Options or Convertible Securities (or upon the occurrence of a record date with respect thereto) and any subsequent adjustments based thereon shall be readjusted to the Issuance Date Conversion Price that would have been in effect had an adjustment been made on the basis that the only Additional Shares of Common so issued were the Additional Shares of Common, if any, actually issued or sold on the exercise of such Options or the conversion of such Convertible Securities, and such Additional Shares of Common, if any, were issued or sold for the consideration actually received by Debtor upon such exercise, plus the consideration, if any, actually received by Debtor for the granting of all such Options, whether or not exercised, plus the consideration received for issuing or selling the Convertible Securities actually converted plus the consideration, if any, actually received by Debtor (other than by cancellation of liabilities or obligations evidenced by such Convertible Securities) on the conversion of such Convertible Securities; and

	(4)		no readjustment pursuant to clauses (2) or (3) above shall have the effect of increasing the Issuance Date Conversion Price to an amount which exceeds the lower of (i) the Issuance Date Conversion Price on the original adjustment date immediately prior to the adjustment), or (ii) the Issuance Date Conversion Price that results from any actual issuance of Additional Shares of Common between the original adjustment date and such readjustment date.

(d) Adjustment of Issuance Date Conversion Price Upon Issuance of Additional Shares of Common. In the event Debtor shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 7(c), without consideration or for a consideration per share less than the Issuance Date Conversion Price in effect on the date or and immediately prior to such issue, then and in such event, the Issuance Date Conversion Price in effect immediately prior to the issuance or such Additional Shares of Common shall be reduced, concurrent with such issue, to an amount (calculated to the nearest one hundredth of one cent ($0.0001)) determined by multiplying the Issuance Date Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of shares of Common Stock that the aggregate consideration received by Debtor for such issuance would purchase at the Issuance Date Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of such Additional Shares of Common; provided that, for the purposes of this Section 7(d), the number of shares of Common Stock outstanding immediately prior to such issuance shall be calculated on a fully diluted basis, as if all Convertible Securities had been fully converted into shares of Common Stock immediately prior to such issuance and any outstanding Options (including those granted pursuant to the Plans) had been fully exercised immediately prior to such issuance (and the resulting securities fully converted into shares of Common Stock, if so convertible) as of such date, but such calculation shall not include any Additional Shares of Common issuable with respect to shares of Convertible Securities, or outstanding Options, solely as a result of the adjustment of the Issuance Date Conversion Price resulting from the issuance of Additional Shares of Common causing such adjustment.

(e) Determination of Consideration. For purposes of this Section 7, the consideration received by Debtor for the issuance of any Additional Shares of Common shall be computed as follows:

(i) Cash and Property. Such consideration shall:

	(1)		insofar as it consists of cash, be computed at the aggregate amount of cash received by Debtor excluding amounts paid or payable for accrued interest or accrued dividends;

	(2)		insofar as it consists of property other than cash, be computed at the Market Price thereof at the time of such issue; and

	(3)		in the event Additional Shares of Common are issued together with other shares or securities or other assets of Debtor for consideration that covers both, by the proportion of such consideration so received, computed as provided in clauses (1) and (2) above, as determined in good faith by the Board of Directors.

(ii) Options and Convertible Securities. The consideration per share received by Debtor for Additional Shares of Common deemed to have been issued pursuant to Section 7(c)(i), relating to Options and Convertible Securities, shall be determined by dividing:

	(1)		the total amount, if any, received or receivable by Debtor as consideration for the issuance of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provisions contained therein for a subsequent adjustment of such consideration) payable to Debtor upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by

	(2)		the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provisions contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities.

(f) Adjustments for Dividends, Distributions, Subdivisions, Combinations or Consolidation of Common Stock.

(i) Stock Dividends, Distributions or Subdivisions. In the event Debtor shall issue Additional Shares of Common pursuant to a stock dividend, stock distribution or subdivision on shares of Common Stock, the Issuance Date Conversion Price in effect immediately prior to such stock dividend, stock distribution or subdivision shall concurrently with such stock dividend, stock distribution or subdivision, be proportionately decreased.

(ii) Combinations or Consolidations. In the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, the Issuance Date Conversion Price in effect immediately prior to such combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased.

(g) No Impairment. Debtor will not, by agreement, amendment to its Certificate of Incorporation or otherwise, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by Debtor but will at all times in good faith assist in the carrying out of all the provisions of this Section 7 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the holders of this Note against impairment.

(h) Certificate as to Adjustments. Upon the occurrence or each adjustment or readjustment of the Issuance Date Conversion Price pursuant to this Section 7, Debtor, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to the holders of this Note a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. Debtor shall, upon the written request at any time of any holder of this Note, furnish or cause to be furnished to such holder a like certificate setting forth (i) all such adjustments and readjustments, (ii) the Issuance Date Conversion Price at the time in effect, and (iii) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of the Note.

8. Representations and Warranties of Debtor. Debtor represents and warrants to Purchaser as follows:

(a) Existence and Good Standing. Debtor is a corporation duly organized, validly existing, and in good standing under the Laws of Delaware. Debtor is duly qualified to transact business and is in good standing as a foreign entity in each jurisdiction where the nature and extent of its business and properties require due qualification and good standing. Debtor (i) possesses all requisite authority, power, licenses, permits and franchises to conduct its business as is now being, or is contemplated to be, conducted, and (ii) and is in compliance with all applicable Laws, except where the failure to be in compliance would not reasonably be expended to have a material adverse effect on Debtor’s ability to perform its obligation under this Note.

9. Representations and Warranties of Purchaser. Purchaser represents and warrants to the Debtor as follows:

(a) Authorization; Enforcement. The Purchaser has the requisite power and authority to enter into this Note and to consummate the transactions contemplated hereby. The Purchaser has taken all necessary action to authorize the execution and delivery of this Note.

(b) Investment Purpose. The Purchaser is purchasing the Note for its own account for investment and not with a present view toward the public sale or distribution thereof and has no intention of selling or distributing or any arrangement or understanding with any other persons regarding the sale or distribution of the Note or any shares of Common Stock issuable on conversion of the Note (“Conversion Shares”), except as contemplated by this Note and in compliance with the Securities Act. The Purchaser will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) this Note or Conversion Shares except in accordance with the provisions of this Note and in accordance with the Securities Act. In making the representation herein, however, except as otherwise provided by this Note, the Purchaser does not agree to hold the Note or Conversion Shares for any minimum or other specified term and reserves the right to dispose of this Note or Conversion Shares at any time in compliance with the Securities Act and the terms of this Note.

(c) Purchaser Status. At the time Purchaser was offered the Note, it was, and at the date hereof it is, an “accredited investor” as defined in Rule 501(a) under the Securities Act.

(d) Reliance on Exemptions. The Purchaser understands that the Note is being offered and sold to it in reliance upon specific exemptions from or non-application of the registration requirements of United States federal and state securities Laws and that the Debtor is relying upon the truth and accuracy of, and the Purchaser’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire this Note.

(e) Acknowledgment of Risk.

(i) The Purchaser acknowledges and understands that its investment in the Note and Conversion Shares involves a significant degree of risk, including, without limitation, (A) an investment in the Debtor is speculative, and only Purchasers who can afford the loss of their entire investment should consider investing in the Debtor and the Note and Conversion Shares; (B) the Purchaser may not be able to liquidate its investment; (C) transferability of the Note and Conversion Shares may be limited; (v) in the event of a disposition of this Note or the Conversion Shares, the Purchaser could sustain the loss of its entire investment; and (D) the Debtor has not paid any dividends on its Common Stock since inception and does not anticipate the payment of dividends in the foreseeable future; and

(ii) The Purchaser is able to bear the economic risk of holding this Note and the Conversion Shares for an indefinite period, and has knowledge and experience in financial and business matters such that it is capable of evaluating the risks of the investment in the Note and the Conversion Shares.

(f) Restrictions on Transfer and Lack of Registration. The Purchaser understands that:

(i) this Note and the Conversion Shares have not been and are not being registered under the Securities Act (other than as which may occur as a result of Purchaser’s participation in a Rights Offering) or any applicable state securities Laws and, consequently, the Purchaser may have to bear the risk of owning the Note or Conversion Shares for an indefinite period of time because the Note or Conversion Shares may not be transferred unless (i) the sale of this Note or Conversion Shares is registered pursuant to an effective registration statement under the Securities Act in connection with a Rights Offering or otherwise; (ii) the Purchaser has delivered to the Debtor an opinion of counsel (in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the Note or Conversion Shares (other than Conversion Shares that are subsequently registered in a Rights Offering or otherwise) to be sold or transferred may be sold or transferred pursuant to an exemption from such registration; or (iii) the Conversion Shares are sold or transferred pursuant to Rule 144; and

(ii) except pursuant to a Rights Offering as contemplated by this Note, neither the Debtor nor any other person is under any obligation to register the sale of the Note or Conversion Shares under the Securities Act or any state or foreign securities Laws or to comply with the terms and conditions of any exemption thereunder.

(g) Legends.

(i) The Purchaser understands that, except for Conversion Shares that may be registered in connection with a Rights Offering contemplated under this Note, the certificates representing the Conversion Shares will bear a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of the certificates for such Conversion Shares, as applicable):

THE SHARES OF COMMON STOCK OF ARGYLE SECURITY, INC. (THE “COMPANY”) REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE OF THE UNITED STATES IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR REGULATIONS THEREUNDER, AND ACCORDINGLY, MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, TRANSFERRED OR ASSIGNED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY SATISFACTORY TO THE COMPANY.

(ii) The Purchaser may request that the Debtor remove, and the Debtor agrees to authorize the removal of any legend from the Conversion Shares (i) following any sale of the Conversion Shares pursuant to an effective registration statement, or (ii) if such Conversion Shares are eligible for sale under Rule 144 without volume limitations or under any no-action letter issued by the SEC (it being understood that the Debtor may obtain an opinion of counsel with respect to such removal of legend). Following the time a legend is no longer required for the Conversion Shares hereunder, the Debtor will, no later than five (5) Business Days following the delivery by a Purchaser to the Debtor or the Debtor’s transfer agent of a legended certificate representing such shares, accompanied by such additional information as the Debtor or the Debtor’s transfer agent may reasonably request, deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from all restrictive and other legends.

(iii) Notwithstanding anything herein to the contrary, the Debtor acknowledges and agrees that the Debtor will not require an opinion of counsel in connection with the transfer of this Note or Conversion Shares by a Purchaser to a Person that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and which transfer involves (i) a partnership transferring to its partners or former partners in accordance with partnership interests; (ii) a corporation transferring to a wholly-owned subsidiary or a parent corporation that owns all of the capital stock of such Purchaser; (iii) a limited liability company transferring to its members or former members in accordance with their interest in the limited liability company; or (iv) an affiliated investment fund transferring to another affiliated investment fund; provided that in each case the transfer is effected in accordance with applicable securities Laws and the transferee agrees in writing, in connection with a transfer of the Note to be subject to the terms of this to the same extent as if the transferee were the Purchaser hereunder.

10. Affirmative Covenants. So long as the Note shall remain unpaid or unsatisfied, Debtor shall:

(a) Notices.

(i) Promptly notify Purchaser of the occurrence of any Event of Default.

(ii) Promptly notify Purchaser of any matter that has resulted or could reasonably be expected to result in a material adverse effect upon the business, operations or properties of Debtor or any of its Subsidiaries, including (A) breach or non performance of, or any default under, a material agreement of Debtor; (B) any material dispute, litigation, investigation, proceeding or suspension between Debtor and any Governmental Authority; or (C) the commencement of, or any material development in, any litigation or proceeding affecting Debtor.

(iii) Promptly notify Purchaser of the occurrence of any (A) sale or disposition of material assets of Debtor, (B) sale, transfer, or assignment of any equity interests held by Debtor in its Subsidiaries, (C) any Change of Control or any event, or the taking of any action by any Person, that could reasonably be expected to cause a Change of Control or (D) incurrence or issuance of any Indebtedness.

(iv) Notify Purchaser of any agreement or expression of intent to take any of the actions described in Section 10(a)(iii) hereof (A) at least 30 days prior to the consummation of such actions or, (B) if such action is a Change of Control that occurs without the consent, agreement or knowledge of Debtor, as soon as reasonably possible after Debtor obtains knowledge of the occurrence of such Change of Control or of any event, or the taking of any action, by any Person that could reasonably be expected to cause, or result in, a Change of Control.

Each notice pursuant to this Section 10(a) shall be accompanied by a statement of a Responsible Officer of Debtor setting forth details of the occurrence referred to therein and stating what action Debtor has taken and proposes to take with respect thereto. In the case of a Notice pursuant to Section 10(a)(iv), Debtor (i) shall provide to Purchaser copies of any related agreements or expressions of intent with respect to the related transaction, other relevant information regarding the transaction and the identity and other relevant information regarding the counterparty (or intended counterparty) to such transaction and the holder of this Note shall be subject to the same terms of any confidentiality obligations to which Debtor is required to be subject and (ii) from time to time prior to the consummation of such transaction shall advise the Purchaser of all material developments regarding such transaction (including at least five Business Days’ notice of the closing date of the transaction). Each notice pursuant to Section 10(a) shall describe with particularity any and all provisions of the Note that have been breached.

(b) Payment of Obligations.

In determining whether or not the interest paid or payable, under any specific contingency, exceeds the maximum rate of interest permitted by applicable law, Debtor and Lender shall, to the maximum extent permitted under applicable law (a) characterize any nonprincipal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, and (c) “spread” the total amount of interest throughout the entire term of this Note so that the interest rate is uniform throughout the entire term hereof.

23. Headings. The headings of the sections of this Note are inserted for convenience only and shall not be deemed to constitute a part hereof.

24. Counterparts. This Note may be executed in one or more counterparts, each of which when so executed and delivered, shall be an original, and all of which together shall constitute one and the same instrument.

25. Entirety. THIS NOTE REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.

(d) No Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of the Voluntary Conversion Amount or the COC Conversion Amount, as applicable, and the number of shares of Common Stock to be issued upon such conversion shall be rounded down to the nearest whole share. Instead of any fractional share of Common Stock which would otherwise be issuable upon conversion of the Voluntary Conversion Amount or the COC Conversion Amount, as applicable, Debtor shall pay a cash adjustment in respect of such fractional interest in an amount equal to the product of (i) the fractional amount, multiplied by, (ii) the QEO Conversion Price or the Issuance Date Conversion Price (as each may be adjusted pursuant to Section 7 hereof), as applicable.

7. Adjustment to Conversion Price for Diluting Issues.

(a) Special Definitions. For purposes of this Section 7, the following definitions shall apply:

(ii) “Convertible Securities” shall mean any evidences of indebtedness, shares (other than Common Stock) and all other securities convertible into or exchangeable for Additional Shares of Common.

(iv) “Options” shall mean rights, options or warrants to subscribe for, purchase or otherwise acquire either Additional Shares of Common or Convertible Securities.

(b) No Adjustment of Conversion Price. No adjustment in the Conversion Price shall be made in respect of the issuance of Additional Shares of Common unless the consideration per share (determined pursuant to Section 7(a)(i) for an Additional Share of Common issued or deemed to be issued by Debtor is less than the Conversion Price, in effect on the date of, and immediately prior to, such issuance.

(i) Options and Convertible Securities. In the event Debtor at any time or from time to time after the Issuance Date and while any portion of this Note is outstanding shall issue any Options or Convertible Securities, other than Options or Convertible Securities exempted pursuant to Section 7(a)(i), or shall fix a record date for the determination of holders of any class of securities entitled to receive any such Options or Convertible Securities, then the maximum number of shares (as set forth in the instrument relating thereto without regard to any provisions contained therein for a subsequent adjustment of such number) of Common Stock issuable upon the exercise of such Options or, in the case of Convertible Securities and Options therefor, the conversion or exchange of such Convertible Securities, shall be deemed to be Additional Shares of Common issued as of the time of such issue or, in case such a record date shall have been fixed, as of the close of business on such record date. Provided that Additional Shares of Common shall not be deemed to have been issued unless the consideration per share (determined pursuant to Section 7(e) hereof) of such Additional Shares of Common would be less than the Conversion Price in effect on the date of and immediately prior to such issue, or such record date, as the case may be, and provided further that in any such case in which Additional Shares of Common are deemed to be issued:

(1) no further adjustment in the Conversion Price shall be made upon the subsequent issuance of Convertible Securities or shares of Common Stock upon the exercise of such Options or conversion or exchange of such Convertible Securities;

(2) if such Options or Convertible Securities by their terms provide, with the passage of time or otherwise, for any increase or decrease in the consideration payable to Debtor, or increase or decrease in the number of shares of Common Stock issuable, upon the exercise, conversion or exchange thereof, the Conversion Price computed upon the original issue thereof (or upon the occurrence of a record date with respect thereto), and any subsequent adjustments based thereon, shall, upon any such increase or decrease becoming effective, be recomputed to reflect such increase or decrease; provided, however, that no such adjustment of the Conversion Price shall affect Common Stock previously issued upon conversion of the Note;

(3) if any such Options or Convertible Securities shall expire without having been exercised or converted, the Conversion Price as adjusted upon the issuance of such Options or Convertible Securities (or upon the occurrence of a record date with respect thereto) and any subsequent adjustments based thereon shall be readjusted to the Conversion Price that would have been in effect had an adjustment been made on the basis that the only Additional Shares of Common so issued were the Additional Shares of Common, if any, actually issued or sold on the exercise of such Options or the conversion of such Convertible Securities, and such Additional Shares of Common, if any, were issued or sold for the consideration actually received by Debtor upon such exercise, plus the consideration, if any, actually received by Debtor for the granting of all such Options, whether or not exercised, plus the consideration received for issuing or selling the Convertible Securities actually converted plus the consideration, if any, actually received by Debtor (other than by cancellation of liabilities or obligations evidenced by such Convertible Securities) on the conversion of such Convertible Securities; and

(4) no readjustment pursuant to clauses (2) or (3) above shall have the effect of increasing the Conversion Price to an amount which exceeds the lower of (i) the Conversion Price on the original adjustment date immediately prior to the adjustment), or (ii) the Conversion Price that results from any actual issuance of Additional Shares of Common between the original adjustment date and such readjustment date.

(d) Adjustment of Conversion Price Upon Issuance of Additional Shares of Common. In the event Debtor shall issue Additional Shares of Common (including Additional Shares of Common deemed to be issued pursuant to Section 7(c), without consideration or for a consideration per share less than the Conversion Price in effect on the date or and immediately prior to such issue, then and in such event, the Conversion Price in effect immediately prior to the issuance or such Additional Shares of Common shall be reduced, concurrent with such issue, to an amount (calculated to the nearest one hundredth of one cent ($0.0001)) determined by multiplying the Conversion Price by a fraction, the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of shares of Common Stock that the aggregate consideration received by Debtor for such issuance would purchase at the Conversion Price, and the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance plus the number of such Additional Shares of Common; provided that, for the purposes of this Section 7(d), the number of shares of Common Stock outstanding immediately prior to such issuance shall be calculated on a fully diluted basis, as if all Convertible Securities had been fully converted into shares of Common Stock immediately prior to such issuance and any outstanding Options (including those granted pursuant to the Plans) had been fully exercised immediately prior to such issuance (and the resulting securities fully converted into shares of Common Stock, if so convertible) as of such date, but such calculation shall not include any Additional Shares of Common issuable with respect to shares of Convertible Securities, or outstanding Options, solely as a result of the adjustment of the Conversion Price resulting from the issuance of Additional Shares of Common causing such adjustment.

(e) Determination of Consideration. For purposes of this Section 7, the consideration received by Debtor for the issuance of any Additional Shares of Common shall be computed as follows:

(i) Cash and Property. Such consideration shall:

(1) insofar as it consists of cash, be computed at the aggregate amount of cash received by Debtor excluding amounts paid or payable for accrued interest or accrued dividends;

(2) insofar as it consists of property other than cash, be computed at the Market Price thereof at the time of such issue; and

(3) in the event Additional Shares of Common are issued together with other shares or securities or other assets of Debtor for consideration that covers both, by the proportion of such consideration so received, computed as provided in clauses (1) and (2) above, as determined in good faith by the Board of Directors.

(1) the total amount, if any, received or receivable by Debtor as consideration for the issuance of such Options or Convertible Securities, plus the minimum aggregate amount of additional consideration (as set forth in the instruments relating thereto, without regard to any provisions contained therein for a subsequent adjustment of such consideration) payable to Debtor upon the exercise of such Options or the conversion or exchange of such Convertible Securities, or in the case of Options for Convertible Securities, the exercise of such Options for Convertible Securities and the conversion or exchange of such Convertible Securities, by

(2) the maximum number of shares of Common Stock (as set forth in the instruments relating thereto, without regard to any provisions contained therein for a subsequent adjustment of such number) issuable upon the exercise of such Options or the conversion or exchange of such Convertible Securities.

(f) Adjustments for Dividends, Distributions, Subdivisions, Combinations or Consolidation of Common Stock.

(i) Stock Dividends, Distributions or Subdivisions. In the event Debtor shall issue Additional Shares of Common pursuant to a stock dividend, stock distribution or subdivision on shares of Common Stock, the Conversion Price in effect immediately prior to such stock dividend, stock distribution or subdivision shall concurrently with such stock dividend, stock distribution or subdivision, be proportionately decreased.

(ii) Combinations or Consolidations. In the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, the Conversion Price in effect immediately prior to such combination or consolidation shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased.

(h) Certificate as to Adjustments. Upon the occurrence or each adjustment or readjustment of the Conversion Price pursuant to this Section 7, Debtor, at its expense, shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to the holders of this Note a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. Debtor shall, upon the written request at any time of any holder of this Note, furnish or cause to be furnished to such holder a like certificate setting forth (i) all such adjustments and readjustments, (ii) the Conversion Price at the time in effect, and (iii) the number of shares of Common Stock and the amount, if any, of other property which at the time would be received upon the conversion of the Note.

13. Subordination. The payment of any amounts owing under this Note, including principal and interest (other than PIK Interest) (“Subordinated Indebtedness”), is subordinated to the payment of any amounts owing (including interest accruing after the filing of a petition initiating any proceeding pursuant to any bankruptcy law with respect to Debtor) under the Senior Indebtedness on the following terms and conditions:

(a) No payment of principal, interest (other than PIK Interest) or any other amounts in respect of this Note shall be paid by Debtor on the Subordinated Indebtedness (whether pursuant to the terms hereof or upon acceleration or otherwise) unless, at the time of any such payment, all of the Senior Indebtedness shall have been paid in full in cash. Notwithstanding the fact that the Subordinated Indebtedness becomes due prior to the Senior Indebtedness, at the Maturity Date of the Subordinated Indebtedness the Debtor shall not make and holder of this Note shall not accept any payment on the Subordinated Indebtedness if, upon the Maturity Date of the Subordinated Indebtedness, Debtor has not paid in full all outstanding obligations arising under the Senior Indebtedness. Notwithstanding any provision of this Section 13 or any other provision of this Note to the contrary, the unpaid principal balance due under this Note, together with any then accrued but unpaid interest, may be converted into Common Stock pursuant to the terms of Section 6, and the holder of this Note may take any action to enforce its rights to such conversion.

(c) The holders of the Subordinated Indebtedness (or a trustee, representative, or agent acting on its behalf) will be obligated to hold in trust for, and to pay over promptly to, the holders of the Senior Indebtedness (or one or more trustees, representatives, or agents acting on their behalf) all payments and distributions received by the holders of the Subordinated Indebtedness (i) in contravention of the restrictions contained in the preceding clauses (a) and (b) of this Section 13 or (ii) as a result of any Lien in violation of clause (d) of this Section 13; provided, however, that notwithstanding such restrictions, the holders of the Subordinated Indebtedness shall be entitled to receive and to retain any and all payments (i) made in securities of Debtor provided the same are subordinated to the Senior Indebtedness at least to the same extent as the Subordinated Indebtedness or (ii) made in accordance with any relevant court order respecting the subordination provided for herein.

(e) The provisions of this Section 13 are irrevocable and the holders of the Senior Indebtedness are intended to be third-party beneficiaries of this Section 13 and such holders may, without notice to any of the parties hereto and without impairing or releasing the obligations of Debtor and the holders of the Subordinated Indebtedness hereunder, (i) change the terms of or increase the amount of the Senior Indebtedness by increasing, extending, rearranging, amending, supplementing, or otherwise modifying any instrument or agreement creating Senior Indebtedness, (ii) sell, exchange, release, or otherwise deal with any collateral securing any Senior Indebtedness, (iii) release anyone, including Debtor or any guarantor, liable in any manner for the payment or collection of any Senior Indebtedness, (iv) exercise or refrain from exercising any rights against Debtor or any other Person, and (v) apply any sums received by any holders of the Senior Indebtedness, from whatever source, to the payment of the Senior Indebtedness. The provisions of this Section 13 shall constitute a continuing agreement among each holder of Senior Indebtedness, Debtor and its Subsidiaries, and all Persons who hold the Subordinated Indebtedness, whether now outstanding or hereafter created, incurred or assumed, and the provisions of this Section 13 are made for the benefit of the holders of the Senior Indebtedness.

(i) increase the rate of interest that is payable on this Note;

(ii) increase the principal of, or accelerate the final Maturity Date of, the Indebtedness evidenced by this Note;

(iii) alter the redemption provisions or the price or terms at which Debtor is required to offer to purchase the Indebtedness evidenced by this Note; or

(iv) amend the provisions of Section 13 of this Note (which relate to subordination) or the related definitions;

(h) The foregoing provisions will be enforceable against the holders of the Subordinated Indebtedness, by or on behalf of any of the holders of the Senior Indebtedness.

(j) Notwithstanding anything to the contrary above, the terms and conditions of this Section 13 shall be null and void and of no further effect once the Senior Indebtedness has been paid in full.

14. Events of Default and Remedies. If any one or more of the following events (each an “Event of Default”) shall occur and be continuing for any reason whatsoever (whether voluntary or involuntary, by operation of law or otherwise):

(a) Debtor shall fail to pay (i) any principal on the MML Bridge Notes or the MML Convertible Notes when due and payable (whether by acceleration or otherwise) or (ii) any interest on the MML Bridge Notes or the MML Convertible Notes due within five (5) days after Debtor’s receipt of written notice that such payment is past due (whether by acceleration or otherwise);

(h) a default or event of default occurs under the Senior Loan Agreement if as a result of such default or event of default the indebtedness under the Senior Loan Agreement is accelerated prior to its maturity; or

then, and in every such event and at any time thereafter during the continuance of such event, Purchaser may by written notice to Debtor (i) declare this Note (together with accrued interest thereon) to be, and this Note shall, subject to Section 13 hereof, thereupon become, immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by Debtor; provided, however, that in the case of any of the Events of Default specified in clauses (f) or (g) above, without any notice to Debtor or any other act by Purchaser, this Note (together with accrued interest thereon) shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by Debtor, and/or (ii) exercise any or all of the rights and remedies which may be taken upon the occurrence and/or during the continuance of Event of Default.

Subject to the terms of Section 13 and the receipt by Purchaser of the prior written consent of each of the holders of the Senior Indebtedness (other than the Corcoran Notes Guaranty) (which consent shall not be unreasonably withheld, delayed or conditioned), Purchaser may sell this Note to any purchaser or purchasers that are Affiliated with the Purchasers (but expressly including for this purpose any limited partners or other equity owners of any of the Purchasers or any other funds Affiliated with the Purchasers or their Affiliates), and in each case, in compliance with the Securities Act or any laws of any State of the United States that regulate the offer and sale of securities. This provision may not be amended without the prior written consent of the parties hereto and each of the holders of the Senior Indebtedness (other than the Corcoran Notes Guaranty).

19. Invalid Provisions. If any provision of this Note is held to be illegal, invalid or unenforceable, (i) the legality, validity and enforceability of the remaining provisions shall not be affected or impaired thereby and (ii) the parties shall endeavor in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction

20. Cumulative Rights. No delay on the part of the holder of this Note in the exercise of any power or right under this Note shall operate as a waiver thereof, nor shall a single or partial exercise of any other power or right.

22. Choice of Law, Venue and Forum. This Agreement, the entire relationship of the parties hereto, and any litigation between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of Texas, without giving effect to its choice of laws principles. Exclusive venue for any litigation between the parties hereto shall be in Bexar County, Texas, and shall be brought in the State District Courts of Bexar County, Texas, or in the United States District Court for the Western District of Texas, San Antonio Division. The parties hereto waive any challenge to personal jurisdiction or venue (including without limitation a challenge based on inconvenience) in Bexar County, Texas, and specifically consent to the jurisdiction of the State District Courts of Bexar County and the United States District Court for the Western District of Texas, San Antonio Division.

23. Usury Savings Clause. Any provision in this Note or in any other document executed in connection herewith, or in any other agreement or commitment, whether written or oral, express or implied, to the contrary notwithstanding, Lender shall not in any event be entitled to receive or collect, nor shall or may amounts received hereunder be credited, so that Lender shall be paid, as interest, a sum greater than the maximum rate of interest permitted by applicable law. If any construction of this Note, or any and all other papers, agreements or commitments, indicates a different right given to Lender to ask for, demand or receive any larger sum as interest, such is a mistake in calculation or wording, which this clause shall override and control; it being the intention of the parties that this Note and all other instruments relating to this Note shall in all things comply with applicable law, and proper adjustment shall automatically be made accordingly. In the event Lender ever receives, collects or applies as interest, any sum in excess of the maximum rate of interest permitted by applicable law, such excess amount shall be applied to the reduction of the unpaid principal balance of this Note in the inverse order of maturity, and if this Note is paid in full, any remaining excess shall be paid to Debtor. In determining whether or not the interest paid or payable, under any specific contingency, exceeds the maximum rate of interest permitted by applicable law, Debtor and Lender shall, to the maximum extent permitted under applicable law (a) characterize any nonprincipal payment as an expense, fee or premium rather than as interest, (b) exclude voluntary prepayments and the effects thereof, and (c) “spread” the total amount of interest throughout the entire term of this Note so that the interest rate is uniform throughout the entire term hereof.

24. Headings. The headings of the sections of this Note are inserted for convenience only and shall not be deemed to constitute a part hereof.

25. Counterparts. This Note may be executed in one or more counterparts, each of which when so executed and delivered, shall be an original, and all of which together shall constitute one and the same instrument.

26. Entirety. THIS NOTE REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS AMONG THE PARTIES.
