FOR VALUE RECEIVED, SENTINEL EMERGENCY RESPONSE TECHNOLOGY, INC., a Nevada Corporation (hereinafter called the “Borrower”), hereby promises to pay to the order of __________, a ___________, or its registered assigns (the “Holder”) the sum of $________, or, if different, the aggregate principal amount outstanding hereunder, on November 9, 2010 (the “Maturity Date”), and to pay interest on the unpaid principal balance hereof at the rate of five percent (5%) (the “Interest Rate”) per annum from the date of delivery of such principal amount to the Borrower as provided below until the same becomes due and payable, whether at maturity or upon acceleration or by prepayment or otherwise. Any amount of principal or interest on this Secured Convertible Note (this “Note”) which is not paid when due shall bear interest at the rate of fifteen percent (15%) per annum from the due date thereof until the same is paid (“Default Interest”). Interest shall commence accruing on the date of delivery of such principal amount to the Borrower as provided below, shall be computed on the basis of a 365-day year and the actual number of days elapsed. All payments due hereunder (to the extent not converted into the Borrower’s common stock, $.001 par value per share (the “Common Stock”), in accordance with the terms hereof) shall be made in lawful money of the United States of America. All payments shall be made at such address as the Holder shall hereafter give to the Borrower by written notice made in accordance with the provisions of this Note. Whenever any amount expressed to be due by the terms of this Note is due on any day which is not a business day, the same shall instead be due on the next succeeding day which is a business day. As used in this Note, the term “business day” shall mean any day other than a Saturday, Sunday or a day on which commercial banks in the city of New York, New York are authorized or required by law or executive order to remain closed.

The Borrower and the Holder acknowledge and agree that upon execution of this Note, the Holder shall deliver to the Borrower $________ of the principal amount under this Note. On the date that the Borrower files the Registration Statement (as defined below) with the SEC (as

defined below), the Holder shall deliver to the Borrower the additional $_______ of principal amount under this Note by wire transfer or delivery of other immediately available funds.

This Note is free from all taxes, liens, claims and encumbrances with respect to the issuance hereof and shall not be subject to preemptive rights or other similar rights of shareholders of the Borrower and will not impose personal liability upon the Holder.

The obligations of the Borrower under its Secured Convertible Notes in the aggregate principal amount of $1,000,000 (the “Convertible Notes”), Secured Convertible Notes in the aggregate principal amount of $70,000 (the “Deferred Convertible Notes”), and Secured Convertible Notes in the aggregate principal amount of $566,615 (of which this Note is one) (the “Loan Notes”) are secured by the collateral set forth in that certain Security Agreement of even date herewith by and among the Borrower, the Holder and certain other parties thereto (the “Security Agreement”). Reference is made to the Security Agreement for a description of the nature and extent of the security for the Convertible Notes, the Deferred Convertible Notes and the Loan Notes and the rights with respect to such security of the Holder. The Convertible Notes, the Deferred Convertible Notes and the Loan Notes are pari passu with respect to the collateral securing such notes and in right of payment; provided, however, that the Deferred Convertible Notes may be paid in full or in part prior to the Conversion Trigger Date (as defined in the Deferred Convertible Notes) (the “Optional Prepayment Exception”). The Convertible Notes, the Deferred Convertible Notes and the Loan Notes are referred to collectively herein as the “Secured Notes”.

The following terms shall apply to this Note:

ARTICLE I. CONVERSION RIGHTS

1.1

Conversion Right. Subsequent to the date the U.S. Securities and Exchange Commission ( the “SEC”) declares the Borrower’s Registration Statement on Form SB-2 (or, if Form SB-2 is not then available, on such form of registration statement as is then available to effect a shelf registration by Borrower of its Common Stock) (the "Registration Statement") registering the resale of the shares of Common Stock underlying the Secured Notes (the "Resale Shares") effective (the “Effective Date”) and at any time thereafter that the Registration Statement is current and effective covering the shares of Common Stock to be issued in connection with a Conversion (as defined below), the Holder shall have the right from time to time, and at any time on or prior to the earlier of (i) the Maturity Date, (ii) the date of payment of the Default Amount (as defined below), or (iii) the date of payment pursuant to Section 1.6(a) or Article III, each in respect of the remaining outstanding principal amount of this Note, to convert all or any part of the outstanding and unpaid principal amount of this Note into fully paid and non-assessable shares of Common Stock, as such Common Stock exists on the date of this Note (the “Issue Date”), or any shares of capital stock or other securities of the Borrower into which such Common Stock shall thereafter be changed or reclassified, at the conversion price (the “Conversion Price”) determined as provided herein (a “Conversion”); provided, however, that in no event shall the Holder be entitled to convert any portion of this Note in excess of that portion of this Note upon conversion of which the sum of (1) the number of shares of Common Stock beneficially owned by the Holder and its affiliates (other than shares of Common Stock

which may be deemed beneficially owned through the ownership of the unconverted portion of this Note or the unexercised or unconverted portion of any other security of the Borrower (including, without limitation, other Secured Notes), subject to a limitation on conversion or exercise analogous to the limitations contained herein), and (2) the number of shares of Common Stock issuable upon the conversion of the portion of this Note with respect to which the determination of this proviso is being made, would result in beneficial ownership by the Holder and its affiliates of more than four and ninety nine hundredths percent (4.99%) of the outstanding shares of Common Stock. For purposes of the proviso to the immediately preceding sentence, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulations 13D-G thereunder, except as otherwise provided in clause (1) of such proviso. The number of shares of Common Stock to be issued upon each conversion of this Note shall be determined by dividing the Conversion Amount (as defined below) by the applicable Conversion Price then in effect on the date of conversion specified in the notice of conversion, in the form attached hereto as Exhibit A (the “Notice of Conversion”), delivered to the Borrower by the Holder in accordance with Section 1.4 below; provided that the Notice of Conversion is submitted by facsimile (or by other means resulting in, or reasonably expected to result in, notice) to the Borrower before 6:00 p.m., New York, New York time on the conversion date specified in the Notice of Conversion (the “Conversion Date”). The term “Conversion Amount” means, with respect to any conversion of this Note, the sum of (1) the principal amount of this Note to be converted in such conversion, plus (2) accrued and unpaid interest, if any, on such principal amount at the interest rates provided in this Note to the Conversion Date, provided, however, that the Borrower shall have the right to pay any or all interest in cash, plus (3) Default Interest, if any, on the amounts referred to in the immediately preceding clauses (1) and/or (2), provided, however, that the Borrower shall have the right to pay any or all Default Interest in cash, plus (4) at the Holder’s option, any amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof. In addition, the Holder agrees that it will limit conversion of all of its Secured Notes in the aggregate to no more than the greater of (1) $20,000, or (2) seven percent (7%) of the aggregate outstanding principal amount of the Secured Notes held by such Holder, per calendar month.

1.2

Conversion Price.

(a)

Calculation of Conversion Price. The Conversion Price shall be the Variable Conversion Price (as defined below) (subject, in each case, to equitable adjustments for stock splits, stock dividends or rights offerings by the Borrower relating to the Borrower’s securities, combinations, recapitalization, reclassifications and similar events). The “Variable Conversion Price” shall mean the Applicable Percentage (as defined below) multiplied by the Market Price (as defined below). “Market Price” means the average of the lowest three (3) Trading Prices (as defined below) for the Common Stock during the twenty (20) Trading Day (as defined below) period ending one Trading Day prior to the Conversion Date. “Trading Price” means, for any security as of any date, the intraday trading price or the closing price, as applicable, on the Pink Sheets, NASD Over-the-Counter Bulletin Board, NASDAQ Global Market, NASDAQ Global Select Market, NASDAQ Capital Market, American Stock Exchange or New York Stock Exchange (collectively, the “Markets”). If the Trading Price cannot be calculated for such security on such date in the manner provided above, the Trading Price shall be the fair market value as mutually determined by the Borrower and a majority of the Holders of the Secured Notes being converted. “Trading Day” shall mean any day on which the

Common Stock is traded for any period on the principal securities exchange or other securities market on which the Common Stock is then being traded. “Applicable Percentage” shall mean fifty percent (50%); provided, however, that the Applicable Percentage shall be increased to (i) fifty five percent (55%) in the event that the Registration Statement is filed on or before the date that is sixty (60) days subsequent to the Issue Date, and (ii) sixty percent (60%) in the event that the Effective Date occurs on a date that is one hundred eighty (180) days subsequent to the Issue Date.

(b)

Conversion Price During Major Announcements. Notwithstanding anything contained in Section 1.2(a) to the contrary, in the event the Borrower (i) makes a public announcement that it intends to consolidate or merge with any other corporation (other than a merger in which the Borrower is the surviving or continuing corporation and its capital stock is unchanged) or sell or transfer all or substantially all of the assets of the Borrower or (ii) any person, group or entity (including the Borrower) publicly announces a tender offer to purchase more than fifty percent (50%) of the Borrower’s outstanding Common Stock (or any other takeover scheme) (the date of the announcement referred to in clause (i) or (ii) is hereinafter referred to as the “Announcement Date”), then the Conversion Price shall, effective upon the Announcement Date and continuing through the Adjusted Conversion Price Termination Date (as defined below), be equal to the lower of (x) the Conversion Price which would have been applicable for a Conversion occurring on the Announcement Date and (y) the Conversion Price that would otherwise be in effect. From and after the Adjusted Conversion Price Termination Date, the Conversion Price shall be determined as set forth in Section 1.2(a). For purposes hereof, “Adjusted Conversion Price Termination Date” shall mean, with respect to any proposed transaction or tender offer (or takeover scheme) for which a public announcement as contemplated by this Section 1.2(b) has been made, the date upon which the Borrower or the person, group or entity consummates or publicly announces the termination or abandonment of the proposed transaction or tender offer (or takeover scheme) which caused this Section 1.2(b) to become operative.

1.3

Authorized Shares. The Borrower covenants that during the period the conversion right exists, the Borrower will use its best efforts to reserve from its authorized and unissued Common Stock a sufficient number of shares, free from preemptive rights, to provide for the issuance of Common Stock upon the full conversion of the then-outstanding Secured Notes. The Borrower will use its best efforts at all times to have authorized and reserved the number of shares that are actually issuable upon full conversion of the then-outstanding Secured Notes (based on the Conversion Price of the Secured Notes in effect from time to time) (the “Reserved Amount”). The Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. In addition, if the Borrower shall issue any securities or make any change to its capital structure which would change the number of shares of Common Stock into which the Secured Notes shall be convertible at the then current Conversion Price, the Borrower shall at the same time make proper provision so that thereafter there shall be a sufficient number of shares of Common Stock authorized and reserved, free from preemptive rights, for conversion of the then-outstanding Secured Notes. The Borrower (i) acknowledges that, upon a Conversion, it will instruct its transfer agent to issue certificates for the Common Stock issuable upon conversion of this Note, and (ii) agrees that its issuance of this Note shall constitute full authority to its officers and agents who are charged with the duty of

executing stock certificates to execute and issue the necessary certificates for shares of Common Stock in accordance with the terms and conditions of this Note.

If at any time the Holder submits a Notice of Conversion and the Borrower does not have sufficient authorized but unissued shares of Common Stock available to effect such conversion in accordance with the provisions of this Article I (a “Conversion Default”), subject to Section 4.8, the Borrower shall issue to the Holder all of the shares of Common Stock which are then available to effect such conversion. The portion of this Note which the Holder included in its Conversion Notice and which exceeds the amount which is then convertible into available shares of Common Stock (the “Excess Amount”) shall, notwithstanding anything to the contrary contained herein, not be convertible into Common Stock in accordance with the terms hereof until (and at the Holder’s option at any time after) the date additional shares of Common Stock are authorized by the Borrower to permit such conversion, at which time the Conversion Price in respect thereof shall be the lesser of (i) the Conversion Price on the Conversion Default Date (as defined below) and (ii) the Conversion Price on the Conversion Date thereafter elected by the Holder in respect thereof. In addition, the Borrower shall pay to the Holder payments (“Conversion Default Payments”) for a Conversion Default in the amount of (x) the sum of (1) the then outstanding principal amount of this Note, plus (2) accrued and unpaid interest on the unpaid principal amount of this Note through the Authorization Date (as defined below), plus (3) Default Interest, if any, on the amounts referred to in clauses (1) and/or (2), multiplied by (y) .24, multiplied by (z) (N/365), where N = the number of days from the day the Holder submits a Notice of Conversion giving rise to a Conversion Default (the “Conversion Default Date”) to the date (the “Authorization Date”) that the Borrower authorizes a sufficient number of shares of Common Stock to effect conversion of the full outstanding principal balance of this Note. The Borrower shall use its best efforts to authorize a sufficient number of shares of Common Stock as soon as practicable following the earlier of (i) such time that the Holder notifies the Borrower or that the Borrower otherwise becomes aware that there are or likely will be insufficient authorized and unissued shares to allow full conversion thereof and (ii) a Conversion Default. The Borrower shall send notice to the Holder of the authorization of additional shares of Common Stock, the Authorization Date and the amount of the Holder’s accrued Conversion Default Payments. The accrued Conversion Default Payments for each calendar month shall be paid in cash or shall be convertible into Common Stock (at such time as there are sufficient authorized shares of Common Stock) at the applicable Conversion Price, at the Borrower’s option, as follows:

(a)

in cash, paid to the Holder by the fifth (5^th) day of the month following the month in which it has accrued, or

(b)

in Common Stock, and the Holder may convert such payment amount into Common Stock at the Conversion Price (as in effect at the time of conversion) at any time after the fifth (5^th) day of the month following the month in which it has accrued in accordance with the terms of this Article I (so long as there is then a sufficient number of authorized shares of Common Stock).

1.4

Method of Conversion.

(a)

Mechanics of Conversion. Subject to Section 1.1, this Note may be converted by the Holder in whole or in part at any time from time to time after the Effective Date, by (A) submitting to the Borrower a Notice of Conversion (by facsimile or other reasonable means of communication dispatched on the Conversion Date prior to 6:00 p.m., New York, New York time) and (B) subject to Section 1.4(b), surrendering this Note at the principal office of the Borrower.

(b)

Surrender of Note Upon Conversion. Notwithstanding anything to the contrary set forth herein, upon conversion of this Note in accordance with the terms hereof, the Holder shall not be required to physically surrender this Note to the Borrower unless the entire unpaid principal amount of this Note is so converted. The Holder and the Borrower shall maintain records showing the principal amount so converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Borrower, so as not to require physical surrender of this Note upon each such conversion. In the event of any dispute or discrepancy, such records of the Borrower shall be controlling and determinative in the absence of manifest error. Notwithstanding the foregoing, if any portion of this Note is converted as aforesaid, the Holder may not transfer this Note unless the Holder first physically surrenders this Note to the Borrower, whereupon the Borrower will forthwith issue and deliver upon the order of the Holder a new Note of like tenor, registered as the Holder (upon payment by the Holder of any applicable transfer taxes) may request, representing in the aggregate the remaining unpaid principal amount of this Note. The Holder and any assignee, by acceptance of this Note, acknowledge and agree that, by reason of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted principal amount of this Note represented by this Note may be less than the amount stated on the face hereof.

(c)

Payment of Taxes. The Borrower shall not be required to pay any tax which may be payable in respect of any transfer involved in the issue and delivery of shares of Common Stock or other securities or property on conversion of this Note in a name other than that of the Holder (or in street name), and the Borrower shall not be required to issue or deliver any such shares or other securities or property unless and until the person or persons (other than the Holder or the custodian in whose street name such shares are to be held for the Holder’s account) requesting the issuance thereof shall have paid to the Borrower the amount of any such tax or shall have established to the satisfaction of the Borrower that such tax has been paid.

(d)

Delivery of Common Stock Upon Conversion. Upon receipt by the Borrower from the Holder of a facsimile transmission (or other reasonable means of communication) of a Notice of Conversion meeting the requirements for conversion as provided in this Section 1.4, the Borrower shall issue and deliver or cause to be issued and delivered to or upon the order of the Holder certificates for the Common Stock issuable upon such conversion within three (3) business days after such receipt (and, solely in the case of conversion of the entire unpaid principal amount hereof, surrender of this Note) (such third business day being hereinafter referred to as the “Deadline”) in accordance with the terms hereof.

(e)

Obligation of the Borrower to Deliver Common Stock. Upon receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed to be the holder of record of the Common Stock issuable upon such conversion, the outstanding principal amount and the amount of accrued and unpaid interest on this Note shall be reduced to reflect such

conversion, and, unless the Borrower defaults on its obligations under this Article I, all rights with respect to the portion of this Note being so converted shall forthwith terminate except the right to receive the Common Stock or other securities, cash or other assets, as herein provided, on such conversion. If the Holder shall have given a Notice of Conversion as provided herein, the Borrower’s obligation to issue and deliver the certificates for Common Stock shall be absolute and unconditional, irrespective of the absence of any action by the Holder to enforce the same, any waiver or consent with respect to any provision thereof, the recovery of any judgment against any person or any action to enforce the same, any failure or delay in the enforcement of any other obligation of the Borrower to the holder of record, or any setoff, counterclaim, recoupment, limitation or termination, or any breach or alleged breach by the Holder of any obligation to the Borrower, and irrespective of any other circumstance which might otherwise limit such obligation of the Borrower to the Holder in connection with such conversion.

(f)

Delivery of Common Stock by Electronic Transfer. In lieu of delivering physical certificates representing the Common Stock issuable upon conversion, provided the Borrower’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program, upon request of the Holder and its compliance with the provisions contained in Section 1.1 and in this Section 1.4, the Borrower shall use its commercially reasonable best efforts to cause its transfer agent to electronically transmit the Common Stock issuable upon conversion to the Holder by crediting the account of the Holder’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission system.

(g)

Failure to Deliver Common Stock Prior to Deadline. Without in any way limiting the Holder’s right to pursue other remedies, including actual damages and/or equitable relief, the parties agree that if delivery of the Common Stock issuable upon conversion of this Note is more than three (3) business days after the Deadline (other than a failure due to the circumstances described in Section 1.3 above, which failure shall be governed by such Section), the Borrower shall pay to the Holder $1,000 per day in cash, for each day beyond the Deadline that the Borrower fails to deliver such Common Stock but in no event shall such payment exceed $5,000 in the aggregate. Such cash amount shall be paid to the Holder by the fifth day of the month following the month in which it has accrued or, at the option of the Holder (by written notice to the Borrower by the first day of the month following the month in which it has accrued), shall be added to the principal amount of this Note, in which event interest shall accrue thereon in accordance with the terms of this Note and such additional principal amount shall be convertible into Common Stock in accordance with the terms of this Note.

1.5

Concerning the Shares. The shares of Common Stock issuable upon conversion of this Note may not be sold or transferred unless (i) such shares are sold pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Act”), or (ii) the Borrower or its transfer agent shall have been furnished with an opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in comparable transactions) to the effect that the shares to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or (iii) such shares are sold or transferred pursuant to Rule 144 under the Act (or a successor rule) (“Rule 144”) or (iv) such shares are transferred to an “affiliate” (as defined in Rule 144) of the Holder who agrees to sell or otherwise transfer the shares only in accordance with this Section 1.5 and who is an

“accredited investor” (as defined in Rule 501 promulgated under the Act) (“Accredited Investor”). Subject to the removal provisions set forth below, until such time as the shares of Common Stock issuable upon conversion of this Note have been registered under the Act or otherwise may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately sold, each certificate for shares of Common Stock issuable upon conversion of this Note that has not been so included in an effective registration statement or that has not been sold pursuant to an effective registration statement or an exemption that permits removal of the legend, shall bear a legend substantially in the following form, as appropriate:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER SAID ACT, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE AND SCOPE CUSTOMARY FOR OPINIONS OF COUNSEL IN COMPARABLE TRANSACTIONS, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT UNLESS SOLD PURSUANT TO RULE 144 OR REGULATION S UNDER SAID ACT.”

The legend set forth above shall be removed and the Borrower shall issue to the Holder a new certificate therefor free of any transfer legend if (i) the Borrower or its transfer agent shall have received an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale or transfer of such Common Stock may be made without registration under the Act and the shares are so sold or transferred, (ii) such Holder provides the Borrower or its transfer agent with reasonable assurances that such Common Stock (to the extent such securities are deemed to have been acquired on the same date) can be sold or transferred pursuant to Rule 144 and the shares are so sold or transferred or (iii) such Common Stock is registered for sale by the Holder under an effective registration statement filed under the Act or otherwise may be sold pursuant to Rule 144 without any restriction as to the number of securities as of a particular date that can then be immediately sold. Nothing in this Note shall affect in any way the Holder’s obligations to comply with applicable prospectus delivery requirements upon the resale of the securities referred to herein.

1.6

Effect of Certain Events.

(a)

Effect of Merger, Consolidation, Etc. At the option of a majority of the Holders of the then-outstanding Secured Notes, the sale, conveyance or disposition of all or substantially all of the assets of the Borrower, the effectuation by the Borrower of a transaction or series of related transactions in which more than fifty percent (50%) of the voting power of the Borrower is disposed of, or the consolidation, merger or other business combination of the Borrower with or into any other Person (as defined below) or Persons when the Borrower is not the survivor shall either: (i) be deemed to be an Event of Default (as defined below) pursuant to which the Borrower shall be required to pay to the Holder upon the consummation of and as a condition to such transaction an amount equal to the Default Amount (as defined below) or (ii)

be treated pursuant to Section 1.6(b) hereof. “Person” shall mean any individual, corporation, limited liability company, partnership, association, trust or other entity or organization.

(b)

Adjustment Due to Merger, Consolidation, Etc. If, at any time when this Note is issued and outstanding and prior to conversion of all of the Secured Notes, there shall be any merger, consolidation, exchange of shares, recapitalization, reorganization, or other similar event other than in connection with a change of the jurisdiction of domestication of the Borrower, as a result of which shares of Common Stock of the Borrower shall be changed into the same or a different number of shares of another class or classes of stock or securities of the Borrower or another entity, or in case of any sale or conveyance of all or substantially all of the assets of the Borrower other than in connection with a plan of complete liquidation of the Borrower, then the Holder of this Note shall thereafter have the right to receive upon conversion of this Note, upon the basis and upon the terms and conditions specified herein and in lieu of the shares of Common Stock immediately theretofore issuable upon conversion, such stock, securities or assets which the Holder would have been entitled to receive in such transaction had this Note been converted in full immediately prior to such transaction (without regard to any limitations on conversion set forth herein), and in any such case appropriate provisions shall be made with respect to the rights and interests of the Holder of this Note to the end that the provisions hereof (including, without limitation, provisions for adjustment of the Conversion Price and of the number of shares issuable upon conversion of this Note) shall thereafter be applicable, as nearly as may be practicable in relation to any securities or assets thereafter deliverable upon the conversion hereof. The Borrower shall not effect any transaction described in this Section 1.6(b) unless (a) it first gives, to the extent practicable, thirty (30) days prior written notice (but in any event at least fifteen (15) days prior written notice) of the record date of the special meeting of shareholders to approve, or if there is no such record date, the consummation of, such merger, consolidation, exchange of shares, recapitalization, reorganization or other similar event or sale of assets (during which time the Holder shall be entitled to convert this Note) and (b) the resulting successor or acquiring entity (if not the Borrower) assumes by written instrument the obligations of this Section 1.6(b). The above provisions shall similarly apply to successive consolidations, mergers, sales, transfers or share exchanges.

(c)

Adjustment Due to Distribution. If the Borrower shall declare or make any distribution of its assets (or rights to acquire its assets) to holders of Common Stock as a dividend by way of return of capital or otherwise (including any dividend or distribution to the Borrower’s shareholders in cash or shares (or rights to acquire shares) of capital stock of a subsidiary (i.e., a spin-off)) (a “Distribution”), then the Holder of this Note shall be entitled, upon any conversion of this Note after the date of record for determining shareholders entitled to such Distribution, to receive the amount of such assets which would have been payable to the Holder with respect to the shares of Common Stock issuable upon such conversion had such Holder been the holder of such shares of Common Stock on the record date for the determination of shareholders entitled to such Distribution.

(d)

Purchase Rights. If at any time when this Note is issued and outstanding, the Borrower issues any convertible securities or rights to purchase stock, warrants, securities or other property (the “Purchase Rights”) pro rata to the record holders of any class of Common Stock, then the Holder of this Note will be entitled to acquire, upon the terms

applicable to such Purchase Rights, the aggregate Purchase Rights which such Holder could have acquired if such Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without regard to any limitations on conversion contained herein) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights or, if no such record is taken, the date as of which the record holders of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights.

(e)

Notice of Adjustments. Upon the occurrence of each adjustment or readjustment of the Conversion Price as a result of the events described in this Section 1.6, the Borrower, at its expense, shall promptly compute such adjustment or readjustment and prepare and furnish to the Holder a certificate setting forth such adjustment or readjustment and showing in detail the facts upon which such adjustment or readjustment is based. The Borrower shall, upon the written request at any time of the Holder, furnish to such Holder a like certificate setting forth (i) such adjustment or readjustment, (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 securities or property which at the time would be received upon conversion of this Note.

1.7

Status as Shareholder. Upon submission of a Notice of Conversion by the Holder, (i) the shares covered thereby (other than the shares, if any, which cannot be issued because their issuance would exceed such Holder’s allocated portion of the Reserved Amount) shall be deemed converted into shares of Common Stock and (ii) the Holder’s rights as a Holder of such converted portion of this Note shall cease and terminate, excepting only the right to receive certificates for such shares of Common Stock and to any remedies provided herein or otherwise available at law or in equity to such Holder because of a failure by the Borrower to comply with the terms of this Note. Notwithstanding the foregoing, if the Holder has not received certificates for all shares of Common Stock prior to the tenth (10th) business day after the expiration of the Deadline with respect to a conversion of any portion of this Note for any reason, then (unless the Holder otherwise elects to retain its status as a holder of Common Stock by so notifying the Borrower) the Holder shall regain the rights of a Holder of this Note with respect to such unconverted portions of this Note and the Borrower shall, as soon as practicable, return such unconverted Note to the Holder or, if this Note has not been surrendered, adjust its records to reflect that such portion of this Note has not been converted. In all cases, the Holder shall retain all of its rights and remedies (including, without limitation, (i) the right to receive Conversion Default Payments pursuant to Section 1.3 to the extent required thereby for such Conversion Default and any subsequent Conversion Default and (ii) the right to have the Conversion Price with respect to subsequent conversions determined in accordance with Section 1.3) for the Borrower’s failure to convert this Note.

ARTICLE II. CERTAIN COVENANTS

2.1

Distributions on Capital Stock. So long as the Borrower shall have any obligation under this Note, without the written consent of a majority of the Holders of the then-outstanding Secured Notes, the Borrower shall not (a) pay, declare or set apart for such payment, any dividend or other distribution (whether in cash, property or other securities) on shares of capital stock other than dividends on shares of Common Stock solely in the form of additional shares of Common Stock, or (b) make any other payment or distribution in respect of its capital

stock except for distributions pursuant to any shareholders’ rights plan which is approved by a majority of the Borrower’s disinterested directors.

2.2

Restriction on Stock Repurchases. So long as the Borrower shall have any obligation under this Note, without the written consent of a majority of the Holders of the then-outstanding Secured Notes, the Borrower shall not redeem, repurchase or otherwise acquire (whether for cash or in exchange for property or other securities or otherwise) in any one transaction or series of related transactions any shares of capital stock of the Borrower or any warrants, rights or options to purchase or acquire any such shares. Notwithstanding anything herein to the contrary, the Borrower may repurchase up to 100,000 shares of its capital stock without the written consent of a majority of the Holders of the then-outstanding Secured Notes.

2.3

Borrowings. So long as the Borrower shall have any obligation under this Note, without the written consent of a majority of the Holders of the then-outstanding Secured Notes, the Borrower shall not create, incur, assume or suffer to exist any liability for borrowed money in excess of $100,000 per annum, except (a) borrowings in existence or committed on the date hereof and of which the Borrower has informed the Holder in writing prior to the date hereof, (b) indebtedness to trade creditors or financial institutions incurred in the ordinary course of business, (c) the Secured Notes, or (d) borrowings, the proceeds of which shall be used to repay this Note.

2.4

So long as the Borrower shall have any obligation under this Note, without the written consent of a majority of the Holders of the then-outstanding Secured Notes, the Borrower shall not sell, lease or otherwise dispose of any significant portion of its assets outside the ordinary course of business. Any consent to the disposition of any assets may be conditioned on a specified use of the proceeds of disposition.

If the Borrower fails to pay the Default Amount within five (5) business days of written notice that such amount is due and payable, then the Holder shall have the right at any time, so long as the Borrower remains in default (and so long and to the extent that there are sufficient authorized shares), to require the Borrower, upon written notice, to immediately issue, in lieu of the Default Amount, the number of shares of Common Stock of the Borrower equal to the Default Amount divided by the Conversion Price then in effect.

ARTICLE IV. MISCELLANEOUS

4.1

Failure or Indulgence Not Waiver. No failure or delay on the part of the Holder in the exercise of any power, right or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such power, right or privilege preclude other or further exercise thereof or of any other right, power or privileges. All rights and

remedies existing hereunder are cumulative to, and not exclusive of, any rights or remedies otherwise available.

4.2

Notices. Any notice herein required or permitted to be given shall be in writing and may be personally served or delivered by courier or sent by United States mail and shall be deemed to have been given upon receipt if personally served (which shall include telephone line facsimile transmission with confirmation receipt) or sent by courier (charges prepaid) or three (3) days after being deposited in the United States mail, certified, with postage pre-paid and properly addressed, if sent by mail. For the purposes hereof, the address of the Holder shall be as shown on the records of the Borrower; and the address of the Borrower shall be 0000 Xxxxxx Xxxxx Xxxxx, Xxxxxxx, Xxxxx 00000, facsimile number: (000) 000-0000. Both the Holder and the Borrower may change the address for service by service of written notice to the other as herein provided.

4.3

Amendments. This Note and any provision hereof may only be amended by an instrument in writing signed by the Borrower and the Holder. The term “Note” and all reference thereto, as used throughout this instrument, shall mean this instrument as originally executed, or if later amended or supplemented, then as so amended or supplemented.

4.4

Assignability. This Note shall be binding upon the Borrower and its successors and assigns, and shall inure to be the benefit of the Holder and its successors and assigns. Each transferee of this Note must be an Accredited Investor. Notwithstanding anything in this Note to the contrary, this Note may be pledged as collateral in connection with a bona fide margin account or other lending arrangement.

4.5

Cost of Collection. If default is made in the payment of this Note, the Borrower shall pay the Holder hereof costs of collection, including reasonable attorneys’ fees.

4.6

Governing Law. THIS NOTE SHALL BE ENFORCED, GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS. THE BORROWER HEREBY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES FEDERAL COURTS LOCATED IN NEW YORK, NEW YORK WITH RESPECT TO ANY DISPUTE ARISING UNDER THIS NOTE, THE AGREEMENTS ENTERED INTO IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. BOTH PARTIES IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH SUIT OR PROCEEDING. BOTH PARTIES FURTHER AGREE THAT SERVICE OF PROCESS UPON A PARTY MAILED BY FIRST CLASS MAIL SHALL BE DEEMED IN EVERY RESPECT EFFECTIVE SERVICE OF PROCESS UPON THE PARTY IN ANY SUCH SUIT OR PROCEEDING. NOTHING HEREIN SHALL AFFECT EITHER PARTY’S RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW. BOTH PARTIES AGREE THAT A FINAL NON-APPEALABLE JUDGMENT IN ANY SUCH SUIT OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON SUCH JUDGMENT OR IN ANY OTHER LAWFUL MANNER. THE PARTY WHICH DOES NOT PREVAIL IN ANY DISPUTE ARISING

UNDER THIS NOTE SHALL BE RESPONSIBLE FOR ALL FEES AND EXPENSES, INCLUDING REASONABLE ATTORNEYS’ FEES, INCURRED BY THE PREVAILING PARTY IN CONNECTION WITH SUCH DISPUTE.

4.7

Certain Amounts. Whenever pursuant to this Note the Borrower is required to pay an amount in excess of the outstanding principal amount (or the portion thereof required to be paid at that time) plus accrued and unpaid interest plus Default Interest on such interest, the Borrower and the Holder agree that the actual damages to the Holder from the receipt of cash payment on this Note may be difficult to determine and the amount to be so paid by the Borrower represents stipulated damages and not a penalty and is intended to compensate the Holder in part for loss of the opportunity to convert this Note and to earn a return from the sale of shares of Common Stock acquired upon conversion of this Note at a price in excess of the price paid for such shares pursuant to this Note. The Borrower and the Holder hereby agree that such amount of stipulated damages is not plainly disproportionate to the possible loss to the Holder from the receipt of a cash payment without the opportunity to convert this Note into shares of Common Stock.

4.8

Allocations of Reserved Amount. The Reserved Amount shall be allocated pro rata among the Holders of the Secured Notes based on the principal amount of such Secured Notes issued to each Holder. Each increase to the Reserved Amount shall be allocated pro rata among the Holders of the Secured Notes based on the principal amount of such Secured Notes held by each Holder at the time of the increase in the Reserved Amount. In the event the Holder shall sell or otherwise transfer any of such Holder’s Secured Notes, each transferee shall be allocated a pro rata portion of such transferor’s Reserved Amount. Any portion of the Reserved Amount which remains allocated to any person or entity which does not hold any Secured Notes shall be allocated to the remaining Holders of the Secured Notes, pro rata based on the principal amount of such Secured Notes then held by such Holders.

4.9

Damages Shares. The shares of Common Stock that may be issuable to the Holder pursuant to Sections 1.3 and 1.4(g) hereof (“Damages Shares”) shall be treated as Common Stock issuable upon conversion of this Note for all purposes hereof and shall be subject to all of the limitations and afforded all of the rights of the other shares of Common Stock issuable hereunder.. For purposes of calculating interest payable on the outstanding principal amount hereof, except as otherwise provided herein, amounts convertible into Damages Shares (“Damages Amounts”) shall not bear interest but must be converted prior to the conversion of any outstanding principal amount hereof, until the outstanding Damages Amounts is zero.

4.10

Denominations. At the request of the Holder, upon surrender of this Note, the Borrower shall promptly issue new Loan Notes in the aggregate outstanding principal amount hereof, in the form hereof, in such denominations of at least $50,000 as the Holder shall request.

4.11

Notice of Corporate Events. Except as otherwise provided below, the Holder of this Note shall have no rights as a holder of Common Stock unless and only to the extent that it converts this Note into Common Stock. The Borrower shall provide the Holder with prior notification of any meeting of the Borrower’s shareholders (and copies of proxy materials and other information sent to shareholders). In the event of any taking by the Borrower

of a record of its shareholders for the purpose of determining shareholders who are entitled to receive payment of any dividend or other distribution, any right to subscribe for, purchase or otherwise acquire (including by way of merger, consolidation, reclassification or recapitalization) any share of any class or any other securities or property, or to receive any other right, or for the purpose of determining shareholders who are entitled to vote in connection with any proposed sale, lease or conveyance of all or substantially all of the assets of the Borrower or any proposed liquidation, dissolution or winding up of the Borrower, the Borrower shall mail a notice to the Holder, at least twenty (20) days prior to the record date specified therein (or thirty (30) days prior to the consummation of the transaction or event, whichever is earlier), of the date on which any such record is to be taken for the purpose of such dividend, distribution, right or other event, and a brief statement regarding the amount and character of such dividend, distribution, right or other event to the extent known at such time. After the Effective Date, the Borrower shall make a public announcement of any event requiring notification to the Holder hereunder substantially simultaneously with the notification to the Holder in accordance with the terms of this Section 4.11.

4.12

Remedies. The Borrower acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to the Holder, by vitiating the intent and purpose of the transaction contemplated hereby. Accordingly, the Borrower acknowledges that the remedy at law for a breach of its obligations under this Note will be inadequate and agrees, in the event of a breach or threatened breach by the Borrower of the provisions of this Note, that the Holder shall be entitled, in addition to all other available remedies at law or in equity, and in addition to the penalties assessable herein, to an injunction or injunctions restraining, preventing or curing any breach of this Note and to enforce specifically the terms and provisions thereof, without the necessity of showing economic loss and without any bond or other security being required.

4.13

Maximum Payments. Nothing contained in this Note shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum permitted by applicable law. In the event that the rate of interest required to be paid or other charges hereunder exceed the maximum rate permitted by such law, any payments in excess of such maximum rate shall be credited against amounts owed by the Borrower to the Holder and thus refunded to the Borrower.

4.14

Registration Statement. Borrower will use its commercially reasonable best efforts to file the Registration Statement with the SEC within 60 days after the Issue Date. Borrower will use its commercially reasonable best efforts to have the Registration Statement declared effective by the SEC as soon as practical and to keep the Registration Statement effective pursuant to Rule 415 under the Act until such date as is the earlier of (i) the date on which all of the Resale Shares have been sold, and (ii) the date on which the all of the remaining Resale Shares may be immediately sold to the public without registration or restriction (including, without limitation, as to volume by each holder thereof) under the Act; provided, however, that the Holder and any subsequent Holder agree that they shall provide Borrower with prior written notice of any proposed sale (the “Resale Notice”) of Resale Shares under the Registration Statement and the prospectus used in connection with the Registration Statement (the “Resale Prospectus”) and shall not make such sale until Borrower shall inform them in writing that the Registration Statement and the Resale Prospectus are current, correct, effective

and available for use in such sale; provided further that, upon receipt of the Resale Notice, Borrower shall promptly use its commercially reasonable best efforts to prepare and file with the SEC such amendments (including post-effective amendments) and supplements to the Registration Statement and the Prospectus as may be necessary to keep the Registration Statement and the Prospectus current, correct, effective and available for use in such sale.

The Holder shall promptly furnish to Borrower such information regarding itself, the Resale Shares held by it and the intended method of disposition of the Resale Shares as shall be reasonably required to effect the registration of the Resale Shares and shall execute such documents in connection with such registration as Borrower may reasonably request. The Holder and any subsequent Holder, by such Holder’s acceptance of this Note, agrees to cooperate with Borrower as reasonably requested by Borrower in connection with the preparation and filing of the Registration Statement, unless such Holder or subsequent Holder has notified Borrower in writing of such Holder’s election to exclude all of such Holder’s Resale Shares from the Registration Statement.

ARTICLE V. CALL OPTION

5.1

Call Option. Notwithstanding anything to the contrary contained in this Article V and other than with respect to the Optional Prepayment Exception, so long as (i) no Event of Default shall have occurred and be continuing, and (ii) the Borrower has a sufficient number of authorized shares of Common Stock reserved for issuance upon full conversion of the Secured Notes, then at any time after the Effective Date, the Borrower shall have the right, exercisable on not less than ten (10) Trading Days prior written notice to the Holders of the then-outstanding Secured Notes (which notice may not be sent to the Holders of the Secured Notes until the Borrower is permitted to prepay all or any portion of the Secured Notes pursuant to this Section 5.1), to prepay all or any portion of the then-outstanding Secured Notes in accordance with this Section 5.1 on a pro rata basis. Any notice of prepayment hereunder (an “Optional Prepayment”) shall be delivered to the Holders of the then-outstanding Secured Notes at their registered addresses appearing on the books and records of the Borrower and shall state (1) that the Borrower is exercising its right to prepay all or a specified portion of the Secured Notes, and (2) the date of such prepayment (the “Optional Prepayment Notice”). On the date fixed for prepayment (the “Optional Prepayment Date”), the Borrower shall make such payment to or upon the order of the Holders as specified by the Holders in writing to the Borrower at least one (1) business day prior to the Optional Prepayment Date. Notwithstanding delivery of an Optional Prepayment Notice and subject to Section 1.1 above, the Holders shall at all times prior to the Optional Prepayment Date maintain the right to convert all or any portion of the Secured Notes in accordance with Article I and any portion of the Secured Notes so converted after receipt of an Optional Prepayment Notice and prior to the Optional Prepayment Date set forth in such notice and such payment shall be deducted from the principal amount of the Secured Notes which are otherwise subject to prepayment pursuant to such Option Prepayment Notice.
