Interest shall be computed on the basis of a year of 365 days for the actual number of days elapsed.

1. All payments of interest and principal shall be in lawful money of the United States of America. All payments shall be applied first to accrued interest, and thereafter to principal.

2. (a) The outstanding principal balance of this Note, together with any accrued and unpaid interest thereon, or any portion thereof, may, at the option of the Holder, be converted into shares of the Series B Preferred Stock of the Company (“Series B Stock”) at any time at a price per share of Series B Stock of $15.00, as equitably adjusted for any stock split or stock dividends effected after the date hereof (the “Conversion Price”).

(b) In case of any reorganization, consolidation or merger involving the Company prior to the Maturity Date, in which the stockholders of the Company receive securities of another entity (including any parent company of the company with which the Company merges or is merged into) (the “Successor Issuer”) in exchange for their shares of Series B Stock, the Successor Issuer shall assume the obligations of the Company under this Note, and this Note shall thereafter be convertible into such securities of the Successor Issuer as the Holder would have been entitled to receive upon consummation of such reorganization, consolidation or merger, if the Holder had converted all of the principal and interest outstanding under this Note immediately prior thereto at the Conversion Price.

(c) Before the Holder shall be entitled to convert this Note pursuant to this Section 2, the Holder shall give written notice to the Company in the form of Annex A hereto at the Company’s principal corporate office, by email, facsimile or otherwise of the election to convert the same and shall state therein the name or names in which the shares of Series B Stock are to be issued. The Company shall, as soon as practicable thereafter, issue and deliver to Holder or to the nominee or nominees of Holder, a certificate or certificates for the Series B Stock to which the Holder shall be entitled as aforesaid. Conversion shall be deemed to have been effected on the date when delivery of notice of an election to convert. All Series B Stock which may be issued upon conversion of the Note will, upon issuance, be duly issued, fully paid and non-assessable and free from all taxes, liens, and charges with respect to the issuance thereof.

3. This Note may be prepaid at any time without the consent of the Holder.

4. The Company shall pay all reasonable attorneys’ fees and court costs incurred by the Holder in enforcing and collecting this Note.

5. The Company hereby waives demand, notice, presentment, protest and notice of dishonor.

6. This Note shall be governed by and construed under the laws of the State of Nevada, as applied to agreements among Nevada residents, made and to be performed entirely within the State of Nevada, without giving effect to conflicts of laws principles.

7. This Note may be transferred only upon its surrender to the Company for registration of transfer, duly endorsed, or accompanied by a duly executed written instrument of transfer in form satisfactory to the Company. Thereupon, this Note shall be reissued to, and registered in the name of, the transferee, or a new Note for like principal amount and interest shall be issued to, and registered in the name of, the transferee. Interest and principal shall be paid solely to the registered holder of this Note. Such payment shall constitute full discharge of the Company’s obligation to pay such interest and principal.
