(d) Absent the occurrence of an Event of Default (unless waived in writing by the Payee), the Maker may prepay this Note for 100% of the full principal amount of this Note, together with all accrued interest thereon, at any time prior to the Maturity Date.

 

2. Events of Default.

(a)  “Event of Default”, wherever used herein, means any one of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body):

(i)  any default in the payment of the principal of, or the interest on, this Note, as and when the same shall become due and payable;

(v) any monetary judgment, writ or similar final process shall be entered or filed against the Maker, any subsidiary or any of their respective property or other assets for more than $300,000, and such judgment, writ or similar final process shall remain unvacated, unbonded or unstayed for a period of 15 calendar days.

(vi)  Maker shall (a) be a party to any Change of Control Transaction (as defined below), (b) agree to sell or dispose all or in excess of 33% of its assets in one or more transactions (whether or not such sale would constitute a Change of Control Transaction), (c) redeem or repurchase more than a de minimis number of shares of Common Stock or other equity securities of Maker, or (d) other than regularly scheduled payments of dividends to the holders of the Maker’s Series A, Series B, Series C and Series D Preferred Stock, make any distribution or declare or pay any dividends (in cash or other property, other than common stock) on, or purchase, acquire, redeem, or retire any of Maker's capital stock, of any class, whether now or hereafter outstanding. “Change of Control Transaction” means the occurrence of any of: (i) an acquisition after the date hereof by an individual or legal entity or “group” (as described in Rule 13d-5(b)(1) promulgated under the Securities Exchange Act of 1934, as amended) of effective control (whether through legal or beneficial ownership of capital stock of Maker, by contract or otherwise) of in excess of 33% of the voting securities of Maker, (ii) a replacement at one time or over time of more than one-half of the members of Maker's board of directors which is not approved by a majority of those individuals who are members of the board of directors on the date hereof (or by those individuals who are serving as members of the board of directors on any date whose nomination to the board of directors was approved by a majority of the members of the board of directors who are members on the date hereof), (iii) the merger of Maker with or into another entity that is not wholly-owned by Maker, consolidation or sale of 33% or more of the assets of Maker in one or a series of related transactions, or (iv) the execution by Maker of an agreement to which Maker is a party or by which it is bound, providing for any of the events set forth above in (i), (ii) or (iii).

(b) If any Event of Default occurs (unless waived in writing by the Payee), 115% of the full principal amount of this Note, together with all accrued interest thereon, shall become, at the Payee's election, immediately due and payable in cash. Commencing 5 days after the occurrence of any Event of Default that results in the acceleration of this Note, the interest rate on this Note shall accrue at the rate of 22% per annum, or such lower maximum amount of interest permitted to be charged under applicable law. The Payee need not provide and Maker hereby waives any presentment, demand, protest or other notice of any kind, and the Payee may immediately and without expiration of any grace period enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Payee at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

 

3.  Most Favored Nations. The Payee shall have the right, in its sole discretion, to convert the principal balance of this Note then outstanding plus accrued but unpaid interest, in whole or in part, into securities of the Maker (or its successor or parent) being issued in any private or public offering of equity securities or indebtedness of the Maker (or its successor or parent) consummated while this Note is outstanding, upon the terms and conditions of such offering, at a rate equal to, for each $1 of principal amount of this Note surrendered, $1 of new consideration offered for such securities. By way of example, if the Payee wishes to surrender $100,000 principal amount of this Note to the Maker as consideration for the purchase of new securities or indebtedness, the Payee shall receive, and the Maker shall issue, $100,000 of new securities (including any securities or other consideration issued or paid to the investors in such offer in connection with the purchase of securities) or indebtedness to the Payee, otherwise on the same terms and conditions as the other participants.

4.  Negative Covenants.  So long as any portion of this Note is outstanding, the Maker will not and will not permit any of its Subsidiaries to directly or indirectly, unless consented to in writing by the Payee:

a) other than Permitted Indebtedness, enter into, create, incur, assume, guarantee or suffer to exist any indebtedness for borrowed money of any kind, including but not limited to, a guarantee, on or with respect to any of its property or assets now owned or hereafter acquired or any interest therein or any income or profits therefrom;

 

b) other than Permitted Liens, enter into, create, incur, assume or suffer to exist any liens of any kind, on or with respect to any of its property or assets now owned or hereafter acquired or any interest therein or any income or profits therefrom;

c) amend its certificate of incorporation, bylaws or other charter documents so as to adversely affect any rights of the Payee other than to increase the number of authorized common shares;

 

d) except as contractually required by the Maker as of the date of issuance of this Note, repay, repurchase or offer to repay, repurchase or otherwise acquire more than a de minimis number of securities;

e) enter into any agreement with respect to any of the foregoing; or

f) other than in respect of the Maker’s Series A, Series B, Series C and Series D Preferred Stock, pay cash dividends or distributions on any equity securities of the Maker.

“Permitted Indebtedness” shall mean (a) the indebtedness of the Maker existing on the date of issuance of this Note, (b) lease obligations and purchase money indebtedness incurred in connection with the acquisition of capital assets and lease obligations with respect to newly acquired or leased assets (c) indebtedness incurred by the Maker that does not mature or require payments of principal prior to the Maturity Date of this Note and is made expressly subordinate in right of payment to the indebtedness evidenced by this Note, as reflected in a written agreement acceptable to the Payee and approved by the Payee in writing, (d) trade receivables in the ordinary course of business, and (e) up to $5,000,000 (five million dollars) in new financing.

“Permitted Lien” shall mean the individual and collective reference to the following: (a) liens for taxes, assessments and other governmental charges or levies not yet due or liens for taxes, assessments and other governmental charges or levies being contested in good faith and by appropriate proceedings for which adequate reserves (in the good faith judgment of the management of the Maker) have been established in accordance with generally accepted accounting procedures, (b) liens imposed by law which were incurred in the ordinary course of business, such as carriers’, warehousemen’s and mechanics’ liens, statutory landlords’ liens, and other similar liens arising in the ordinary course of business, and (x) which do not individually or in the aggregate materially detract from the value of such property or assets or materially impair the use thereof in the operation of the business of the Maker and its consolidated subsidiaries or (y) which are being contested in good faith by appropriate proceedings, which proceedings have the effect of preventing the forfeiture or sale of the property or asset subject to such lien and (c) liens of the Maker existing on the date of issuance of this Note, including liens incurred in connection with the Permitted Indebtedness.

The recapitalization proposed to investors in December 2007 is excluded from this Section 4.

5. No Waiver of Payee’s Rights. All payments of principal and interest shall be made without setoff, deduction or counterclaim. No delay or failure on the part of the Payee in exercising any of its options, powers or rights, nor any partial or single exercise of its options, powers or rights shall constitute a waiver thereof or of any other option, power or right, and no waiver on the part of the Payee of any of its options, powers or rights shall constitute a waiver of any other option, power or right. Maker hereby waives presentment of payment, protest, and all notices or demands in connection with the delivery, acceptance, performance, default or endorsement of this Note. Acceptance by the Payee of less than the full amount due and payable hereunder shall in no way limit the right of the Payee to require full payment of all sums due and payable hereunder in accordance with the terms hereof.

6.  Modifications. No term or provision contained herein may be modified, amended or waived except by written agreement or consent signed by the party to be bound thereby.

7.  Cumulative Rights and Remedies; Usury. The rights and remedies of Payee expressed herein are cumulative and not exclusive of any rights and remedies otherwise available under this Note or applicable law (including at equity). The election of Payee to avail itself of any one or more remedies shall not be a bar to any other available remedies, which Maker agrees Payee may take from time to time. If it shall be found that any interest due hereunder shall violate applicable laws governing usury, the applicable rate of interest due hereunder shall be reduced to the maximum permitted rate of interest under such law.

8.  Use of Proceeds. Maker shall use the proceeds from this Note hereunder for working capital purposes and not for the satisfaction of any portion of Maker’s or subsidiary’s debt (other than payment of trade payables in the ordinary course of Maker's business and prior practices), to redeem any of Maker’s or subsidiary’s equity or equity-equivalent securities or to settle any outstanding litigation.

9.  Collection Expenses. If Payee shall commence an action or proceeding to enforce this Note, then Maker shall reimburse Payee for its costs of collection and reasonable attorneys fees incurred with the investigation, preparation and prosecution of such action or proceeding.

10.  Severability. If any provision of this Note is declared by a court of competent jurisdiction to be in any way invalid, illegal or unenforceable, the balance of this Note shall remain in effect, and if any provision is inapplicable to any person or circumstance, it shall nevertheless remain applicable to all other persons and circumstances. If it shall be found that any interest or other amount deemed interest due hereunder shall violate applicable laws governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum permitted rate of interest.

11.  Successors and Assigns. This Note shall be binding upon Maker and its successors and shall inure to the benefit of the Payee and its successors and assigns. The term "Payee" as used herein, shall also include any endorsee, assignee or other holder of this Note.

12.  Lost or Stolen Promissory Note. If this Note is lost, stolen, mutilated or otherwise destroyed, Maker shall execute and deliver to the Payee a new promissory note containing the same terms, and in the same form, as this Note. In such event, Maker may require the Payee to deliver to Maker an affidavit of lost instrument and customary indemnity in respect thereof as a condition to the delivery of any such new promissory note.

13.  Due Authorization. This Note has been duly authorized, executed and delivered by Maker and is the legal obligation of Maker, enforceable against Maker in accordance with its terms except as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally. No consent of any other party and no consent, license, approval or authorization of, or registration or declaration with, any governmental authority, bureau or agency is required in connection with the execution, delivery or performance by the Maker, or the validity or enforceability of this Note other than such as have been met or obtained. The execution, delivery and performance of this Note and all other agreements and instruments executed and delivered or to be executed and delivered pursuant hereto or thereto or the securities issuable upon conversion of this Note will not violate any provision of any existing law or regulation or any order or decree of any court, regulatory body or administrative agency or the certificate of incorporation or by-laws of the Maker or any mortgage, indenture, contract or other agreement to which the Maker is a party or by which the Maker or any property or assets of the Maker may be bound.

14.  Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Note shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each of Maker and Payee agree that all legal proceedings concerning the interpretations, enforcement and defense of this Note shall be commenced in the state and federal courts sitting in the City of New York, Borough of Manhattan (the "New York Courts"). Each of Maker and Payee hereby irrevocably submit to the exclusive jurisdiction of the New York Courts for the adjudication of any dispute hereunder (including with respect to the enforcement of this Note), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper.
