5. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF THE HOLDER.  The Holder hereby represents and warrants to, and agrees with, the Company that:

5.1 Authorization.  This Note constitutes the Holder’s valid and legally binding obligation, enforceable in accordance with its terms except as may be limited by  (a) applicable bankruptcy, insolvency, reorganization or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and (b) the effect of rules of law governing the availability of equitable remedies.  The Holder represents that it has full power and authority to enter into this Note.

5.2 Purchase for Own Account.  This Note will be acquired for investment for the Holder’s own account, not as a nominee or agent, and not with a view to the public resale or distribution thereof within the meaning of the Securities Act, and the Holder has no present intention of selling, granting any participation in, or otherwise distributing the same.  If not an individual, the Holder also represents that the Holder has not been formed for the specific purpose of acquiring this Note, or, if the Holder has been formed for the specific purpose of acquiring this Note, then each and all of the record, beneficial, or equitable owners of the Holder are accredited investors by virtue of satisfying one of the categories established for determining accredited investor status as set forth in Section 5.5 below.

5.3 Disclosure of Information.  The Holder has received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to this Note.  The Holder further has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Note and to obtain additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to the Holder or to which the Holder had access.

5.4 Investment Experience.  The Holder understands that the purchase of this Note involves substantial risk.  The Holder (a) has experience as an investor in securities of companies in the development stage and acknowledges that the Holder is able to fend for itself, can bear the economic risk of the Holder’s investment in the Note and has such knowledge and experience in financial or business matters that the Holder is capable of evaluating the merits and risks of this investment in the Note and protecting its own interests in connection with this investment and (b) has a preexisting personal or business relationship with the Company and certain of its officers, partners or controlling persons of a nature and duration that enables the Holder to be aware of the character, business acumen and financial circumstances of such persons.

5.5 Accredited Investor Status.  The Holder is an “accredited investor” within the meaning of Rule 501(a) of Regulation D promulgated under the Securities Act because the Holder either is (a) an individual whose net worth, or joint net worth with the Holder’s spouse, exceeds One Million Dollars ($1,000,000) (for purposes of determining net worth (i) the primary residence owned by the Holder must be excluded from the net worth calculation, (ii) the related amount of indebtedness secured by the primary residence up to the fair market value of that residence may also be excluded from the calculation, and (iii) indebtedness secured by the primary residence in excess of the fair market value of that residence should be considered a liability and deducted from the Holder’s net worth); (b) an individual whose individual income exceeded Two Hundred Thousand Dollars ($200,000) (exclusive of any income attributable to the Holder’s spouse) in each of the two most recent years, with an expectation of reaching the same income level in the current year; (c) an individual whose joint income with the Holder’s spouse exceeded Three Hundred Thousand Dollars ($300,000) in each of the two most recent years, with an expectation of reaching the same income level in the current year; (d) a corporation, partnership, or business trust which has total assets in excess of Five Million Dollars ($5,000,000) and was not formed for the specific purpose of acquiring the Note; (e) an entity comprised of equity owners who are all accredited investors; or (f) a private business development company as defined in Section 202(a)(22) of the Investment Advisers Act of 1940.

5.6 Restricted Securities.  The Holder understands that this Note is characterized as a “restricted security” under the Securities Act and Rule 144 promulgated thereunder inasmuch as it is being acquired from the Company in a transaction not involving a public offering, and that under the Securities Act and applicable regulations thereunder such securities may be resold without registration under the Securities Act only in certain limited circumstances.  In this connection, the Holder is familiar with Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.  The Holder understands that the Company is under no obligation to register any of the Notes sold hereunder.  The Holder understands that no public market now exists for any of the Notes and that it is unlikely that a public market will ever exist for the Notes.

5.7 No Solicitation.  At no time was the Holder presented with or solicited by any publicly issued or circulated newspaper, mail, radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Notes.

5.8 Further Limitations on Disposition.  Without in any way limiting the representations set forth above, the Holder further agrees not to make any disposition of all or any portion of this Note unless and until:

(a) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(b) the Holder shall have notified the Company of the proposed disposition, and shall have furnished the Company with a statement of the circumstances surrounding the proposed disposition, and, at the expense of the Holder or its transferee, with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration of the Note under the Securities Act.

Notwithstanding the provisions of paragraphs (a) and (b) above, no such registration statement or opinion of counsel shall be required:  (i) for any transfer of this Note in compliance with Rule 144 or Rule 144A; or (ii) for any transfer of this Note by the Holder to (A) a partner of the Holder, (B) a controlled affiliate of the Holder, (C) a retired partner of the Holder who retires after the date hereof, or (D) the estate of any such partner; provided that in each of the foregoing cases the transferee agrees in writing to be subject to the terms of this Section 5 to the same extent as if the transferee were the original Holder hereunder.

SECURITY AND SUBORDINATION.  The Holder acknowledges that this Note is an obligation of the Company.  The Holder also acknowledges that this Note shall be repaid from the proceeds of equity, debt or other capital raises and other cash flow into the Company from revenue generated from the sale of the Company’s products and/or services.  The Holder consents to the Company obtaining additional debt some of which may be senior to the Note.

8. LEFT INTENTIONALLY BLANK.

9. LEFT INTENTIONALLY BLANK.  

10. USE OF PROCEEDS.  The Company intends to utilize the proceeds of this Note for the ongoing operation and expansion of the Company, including, but not limited to, working capital, acquisitions, and other general corporate uses.

25. CONVERSION RIGHTS.  Subject to prior payment or conversion in full of this Note, all or any portion of the Note shall, at the election of the Holder or at the election of the Company made at any time after issuance, convert automatically into a number of shares of common stock of the Company (the “Conversion Shares”) which is determined by dividing (a) the Purchase Amount plus any accrued and unpaid interest plus the accrued pro rata Discount outstanding and to be converted on the date of conversion by (b) the conversion price of $0.40 per share of common stock (the “Conversion Price”).  Conversion under this Section 25 shall occur following written notice by the Company given to the Holder, or by the Holder to the Company, as applicable, in the manner provided in Section 20, at which time the Holder shall endorse and surrender this Note for conversion at the principal offices of the Company and execute and deliver to the Company the forms of stock purchase agreement, investors’ rights agreement, right of first refusal and co-sale agreement, voting agreement, and other agreements and related documents as are requested by the Company, containing terms, conditions, limitations and restrictions customarily entered into in similar financings.  Notwithstanding the foregoing, conversion of this Note hereunder will be effective on the date of the Company’s notice of conversion whether or not the Holder endorses this Note and delivers it to the Company for cancellation or executes and delivers the required financing agreements to the Company.  Absent receipt by the Company of such items from the Holder, the Company will convert this Note into Conversion Shares on the terms set forth herein, but the Holder will not be entitled to receive the certificate for such Conversion Shares unless and until the Holder executes and delivers to the Company all items required under this Section 25.

27. CHANGE OF CONTROL.  In the event of a “change in control” of the Company, all amounts owed under this Note will be immediately due and payable. The Holder may elect to be paid either (a) the Purchase Amount plus the accrued pro rata Discount then outstanding on this Note, or (b) an amount equal to the amount the Holder would receive if the Holder immediately converted all amounts owed under this Note to common stock at the Conversion Price set forth in Section 25 and sold the Conversion Shares at the same price per share as the price paid per share for the shares issued or acquired to affect the “change in control.” A “change in control” is generally defined as (i) the acquisition by any person of 50% or more of the combined voting power of the Company’s outstanding securities, or (ii) the occurrence of a transaction requiring shareholder approval and involving the sale of all or substantially all of the assets of the Company or the merger of the Company with or into another corporation.

28. CONFIDENTIALITY.   The Holder agrees that it will keep confidential and will not disclose, divulge, or use for any purpose (other than to monitor its investment in the Company) any confidential information obtained from the Company pursuant to the terms of this Note or otherwise, unless such confidential information (a) is known or becomes known to the public in general (other than as a result of a breach of this Section 28 by the Holder), (b) is or has been independently developed or conceived by the Holder without use of or resort to the Company’s confidential information, or (c) is or has been made known or disclosed to the Holder by a third party without a breach of any obligation of confidentiality such third party may have to the Company; provided, however, that the Holder may disclose confidential information (i) to its attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring the Holder’s investment in the Company; (ii) to any existing affiliate, partner, member, stockholder, or wholly owned subsidiary of the Holder in the ordinary course of business, provided that the Holder informs such person or entity that such information is confidential and directs such person or entity to maintain the confidentiality of such information; or (iii) as may otherwise be required by law, provided that the Holder promptly notifies the Company of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure.
