CONVERTIBLE PROMISSORY NOTE

FOR VALUE RECEIVED, the undersigned Kesselring Holding Corporation, a Delaware corporation (the “Company”), promises to pay to the order of James K. Toomey (“Payee”, and Payee and any subsequent permitted holder(s) of this Note being referred to collectively as “Holder”), at Holder’s address set forth below (or by wire transfer to Holder’s wire address set forth below) or at such other place as Holder may designate in writing pursuant to the notice provisions below, the principal sum of TEN THOUSAND DOLLARS ($10,000.00) (the “Principal Amount”), together with accrued and unpaid interest thereon, said principal and interest to be due and payable as stated below.

This convertible promissory note (the “Note”) is issued pursuant to the terms of that certain Convertible Promissory Note Purchase Agreement (as amended, the “Purchase Agreement”) dated as of October 24, 2014 by and between the Company and the Payee. Capitalized terms used herein without definition shall have the meanings given to such terms in the Purchase Agreement.

1. Interest Rate. The Company promises to pay simple interest on the outstanding principal amount of this Note from October 21, 2013 (the date that the underlying loan was originally made by the Holder to the Company) until paid in full at the fixed rate of three and one-half percent (3.5%) per annum. Interest shall be calculated on a 365-day year basis and shall be due and payable as set forth below.

2. Maturity. Unless this Note has been previously converted in accordance with the terms of Section 5 hereof, all outstanding principal and accrued and unpaid interest on this Note, plus all fees, costs and expenses then due under this Note, become fully due and payable upon demand by the Holder (the “Maturity Date”); provided, however, that no demand for payment shall be made prior to earlier of: (a) June 1, 2015, and (b) thirty (30) calendar days after the Recommencement of Public Company Status (defined in Section 5(d) below).

3. Payments. No principal amount of this Note or any accrued interest on the principal balance of this Note is due or payable until the Maturity Date.

4. Prepayment. The Company may not prepay this Note prior to the Maturity Date without the consent of the Holder. Following the Maturity Date, the Company may prepay any part or all of any amount payable under this Note, including principal or interest or both, at any time or times without any premium or penalty whatsoever. Any and all prepayments shall be applied first to reimbursement of Holder for any costs or expenses incurred by Holder to enforce or collect amounts owed hereunder, then to repayment of any accrued and unpaid interest hereunder, and then to principal outstanding hereunder.

5. Optional Conversion of Note.

(a) Optional Conversion Rights. The outstanding principal balance of this Note shall be convertible, in whole or in part, at the option of the Holder at any time prior to the Maturity Date, into shares of common stock, par value $0.0001 per share, of the Company (“Common Stock”), at the then-Conversion Price (as defined in Section 5(d) below) (the “Optional Conversion Right”), commencing upon the earliest of any of the following:

(i) the date that the Company takes all corporate action necessary to increase the number of authorized shares of Common Stock in an amount sufficient to issue those shares of Common Stock issuable upon the exercise of the Optional Conversion Right, in whole or in part, by the Holder,

(ii) Sale of the Company (as defined in Section 5(d) below), or

(iii) immediately prior to the closing of any equity financing or issuance of debt securities by the Company in a transaction or a series of related transactions resulting in aggregate proceeds of at least One Hundred Thousand Dollars ($100,000).

The date that the Optional Conversion Right first becomes available to the Holder is referred to herein as “Determination Date.” To the extent that the Holder decides to exercise his or her Optional Conversion Right, then any unpaid interest on this Note shall be converted into Common Stock on the same terms as the principal of the Note.

(b) Covenants of Company. The Company hereby agrees that it will take all steps required under applicable law to have authorized on or prior to Recommencement of Public Company Status and thereafter to reserve and keep available, solely for issuance and delivery to the Holder, that number of shares of its Common Stock (or other securities and property) that may be required from time to time for issuance and delivery upon the exercise of the Optional conversion Right afforded by this Note. The Company shall take all action as may be necessary to assure that such shares of Common Stock (and any other securities and property) may be issued and delivered as provided herein without violation of any applicable law or regulation, or of any requirements, of any domestic securities exchange or inter-dealer quotation system upon which the Common Stock may be listed;

(c) Exercise of Optional Conversion Right. The Optional Conversion Right may be exercised by the Holder, in whole but not in part, at any time, and from time to time after the Determination Date and prior to the Maturity Date, by the surrender and presentment of this Note accompanied by a duly executed Notice of Exercise in the form attached hereto (the “Exercise Notice”), presented to the Company, at its principal office or at such other place as the Company may designate by notice in writing to the Holder.

(d) Definitions. For purposes of this Note:

(i) The “Conversion Price” shall be the average of the mean of the bid and asked prices of Common Stock as quoted on any inter-dealer quotation system or pink sheets (as reported by the Wall Street Journal or, if not reported thereby, any other authoritative source selected by the Company) for the ninety (90) consecutive full trading days in which such shares were traded ending at the close of trading on the fifth business day preceding the Determination Date.

(ii) The term “Recommencement of Public Company Status” shall mean such time as when the Company revives its filing obligations under section 13 or 15(d) of the Securities Exchange Act of 1934 (“Exchange Act”) by filing a Form 8-K or a Form 10-K with the Securities and Exchange Commission.

(ii) The “Sale of the Company” shall mean (A) any consolidation or merger of the Company with or into any other corporation or other entity or person, or any other corporate reorganization, other than any such consolidation, merger or reorganization in which the shareholders of the Company immediately prior to such consolidation, merger or reorganization, continue to hold at least a majority of the voting power of the surviving entity in substantially the same proportions (or, if the surviving entity is a wholly owned subsidiary, its parent) immediately after such consolidation, merger or reorganization; (B) any transaction or series of related transactions to which the Company is a party in which in excess of 50% of the Company’s voting power is transferred; provided, however, that a Sale of the Company shall not include any transaction or series of transactions principally for bona fide equity financing purposes in which cash is received by the Company or any successor or indebtedness of the Company is cancelled or converted or a combination thereof; or (C) a sale, lease, exclusive license or other disposition of all or substantially all of the assets of the Company.

No delay by Holder in enforcing its rights hereunder or otherwise, shall prejudice Holder’s rights to enforce this Note. Neither Party to this Note will be liable to the other for any failure or delay in performance under this Note due to circumstances beyond its reasonable control including, without limitation, Acts of God, labor disruption, war, terrorist threat or government action, or lack of availability of wire transfer systems or other international or national systems; provided, that if either party is unable to perform its obligations under this Note for one of these reasons it shall give prompt written notice thereof to the other party and the time for performance, if any, shall be deemed to be extended for a period equal to the duration of the conditions preventing performance.
