Maturity. The principal and accrued interest on this Note shall be due and payable by the Company on the earlier of (a) December 31, 2023 or (b) five (5) business days following the consummation of a Qualified Financing. For the purposes of this Note, a “Qualified Financing” shall mean, without duplication, to the extent occurring after the date hereof, (a) any sale (or series of related sales) by the Company of (i) the Company’s Common Stock (the “Common Stock”) or Preferred Stock (the “Preferred Stock”), (ii) any equity securities conferring the right to purchase the Common Stock or Preferred Stock or which are convertible into, or exchangeable for (with or without additional consideration), the Common Stock or Preferred Stock (except any security granted, issued and/or sold by the Company to any director, officer, employee or consultant of the Company in such capacity for the primary purpose of retaining their services), or (iii) any debt securities (whether or not conferring the right to purchase the Common Stock or Preferred Stock) or which are convertible into, or exchangeable for (with or without additional consideration), the Common Stock or Preferred Stock, in each case, the aggregate proceeds of which equal or exceed $50,000,000 less reasonable costs and expenses; or (b) the receipt by the Company of aggregate gross proceeds in any debt financing (or series of debt financings) equal to or exceeding $50,000,000, less reasonable costs and expenses.

Short Term Notes. This Note is one in a series of such Notes (the “Short Term Notes”) that may be issued by the Company on substantially the same terms prior to, on or following the date hereof. The holders of the Short Term Notes representing at least eighty-five percent (85%) of the outstanding principal amount of all Short Term Notes are referred to herein as the “Majority Holders”.

Interest. Interest shall begin to accrue on the outstanding principal balance of this Note commencing on the date hereof and continuing until, and shall become payable upon, repayment of this Note in full at the rate of fifteen percent (15%) per annum. Interest shall be calculated on the basis of a 360 day year and actual days elapsed.

Prepayment. The outstanding principal balance and all accrued interest payable to Holder hereunder may be prepaid in whole or in part by the Company with no penalty of any kind.

Default. For purposes of this Note, the term “Default” shall include any of the following:

(a)

The failure by the Company to pay any amounts due hereunder when due;

(b)

A material breach by the Company of any other term or provision of this Note or of any representation or warranty made by the Company in this Note; or

(c)

The filing of a petition in bankruptcy or under any similar insolvency law by the Company, the making of an assignment for the benefit of creditors by the Company, the commencement of any proceeding against the Company seeking any bankruptcy reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation and such petition is not dismissed within forty-five (45) days after the filing thereof, or within forty-five (45) days after the appointment without the consent or acquiescence of the Company of any trustee, receiver or liquidator of the Company, or of all or any substantial part of the properties of the Company, such appointment shall not have been vacated.

If a Default pursuant to Sections 5(a) and 5(b) occurs and is continuing, the Holder, by written notice to the Company, may declare due and payable the unpaid principal balance and all accrued interest on this Note. Upon the occurrence of a Default pursuant to Section 5(c), the unpaid principal balance and all interest accrued thereon shall automatically be due and payable immediately, without notice from or other action by the Holder. If a Default with respect to this Note occurs and is continuing, the Holder may pursue any available remedy by proceeding at law or in equity to collect any amounts due with respect to this Note or to enforce the performance of any provision of this Note.

The Holder shall have all rights and remedies available to it upon any Default and all amounts past due shall continue to accrue interest at the interest rate applicable to this Note until the earlier of conversion pursuant to Section 5(y) or the time at which all obligations under this Note are paid in full. Upon the occurrence of a Default pursuant to Section 5(a) that has not been cured by the Company within five (5) days after such Default:

(x) the Company agrees to immediately issue, or to the extent the Stockholders’ Approval pursuant to Section 6 has not yet been obtained, to issue immediately upon receipt of the Stockholders’ Approval, a warrant (the “Warrant”) for the purchase of Common Stock in form attached hereto as Exhibit A (the “Warrant Agreement”), which shall entitle the Holder to purchase at an exercise price per share of $0.01 a number of shares of Common Stock equal to (i) (A) 0.2 multiplied by (B) the amount of outstanding principal and accrued interest under this Note as of the date of conversion pursuant to Section 5(y) hereof, divided by (ii) the volume weighted average price of each share of Common Stock, as reported by the New York Stock Exchange, for the last

- 2 -

five (5) trading days (as of any applicable measurement date, the “Common Stock VWAP”) occurring immediately prior to the date of exercise; and

(y) the Holder may elect, at its option, by written notice to the Company (a “Conversion Notice”), to convert the amount of outstanding principal and accrued interest under this Note into a number of shares of Common Stock (the “Conversion Securities”) equal to (i) the amount of outstanding principal and accrued interest under this Note as of the date of such conversion, divided by (ii) the lesser of the price per share of (A) the Common Stock, as reported by the New York Stock Exchange, as of 4:00 P.M. Eastern Time on the date of the Conversion Notice or (B) the Common Stock VWAP as of the day prior to the date of the Conversion Notice.

As promptly as practicable after the conversion of this Note, the Company at its expense shall issue and deliver to the Holder, upon surrender of the Note, a certificate or certificates for the number of full Conversion Securities issuable upon such conversion.

Notwithstanding anything in this Note to the contrary, the Holders’ right to convert this Note and receive the Conversion Securities shall be subject to the Company obtaining the Stockholders’ Approval.

The Company shall reserve and keep available out of its authorized but unissued Common Stock such number of shares issuable as Conversion Securities and such number of Warrant Shares (as defined in the Warrant Agreement) upon the full exercise of the Warrant. During the term of this Note, the Company shall not take any action which would cause the number of authorized but unissued Common Stock to be less than the number of such shares required to be reserved hereunder for issuance as Conversion Securities and upon full exercise of the Warrant.

Stockholders’ Approval. The Company, acting through its Board of Directors, shall, in accordance with applicable law, the rules of the NYSE (the “NYSE Listing Rules”) and the Company’s Certificate of Incorporation and Bylaws, include one or more proposals at the next annual or special meeting of its stockholders (whichever is earlier) following the execution of this Note (including any adjournment, recess, reconvening of postponement thereof, the “Stockholders’ Meeting”) for the purpose of obtaining all necessary approvals for the issuance of the Warrant Agreement and the Conversion Securities to the Holder and all other investors investing in the Short Term Notes that may be issued by the Company on substantially the same terms prior to, on or following the date hereof, including (1) as may be required pursuant to the NYSE Listing Rules, including, without limitation, pursuant to Section 312.03(b) of the NYSE Listed Company Manual (the related party issuance rule), Section 312.03(c) of the NYSE Listed Company Manual (the 20% rule) and Section 312.03(d) of the NYSE Listed Company Manual (the change of control rule), in each case, to the extent applicable, (2) to the extent necessary, to amend the Company’s Certificate of Incorporation to increase the number of shares of Common Stock authorized for issuance thereunder and (3) as needed pursuant to any other regulations of any public regulatory body or self-regulatory organization having jurisdiction thereof (the “Stockholders’ Approval”).
