Whenever any amount expressed to be due by the terms of this Note is due on any day which is not a Business Day, the same shall instead be due on the next succeeding day which is a Business Day.

Section 5. Conversion.

	a.	Conversion Right. Subject to the terms hereof and restrictions and limitations contained herein, the Holder shall have the right, at the Holder’s sole option, at any time and from time to time to convert in whole or in part the outstanding and unpaid Principal Amount under this Note into shares of Common Stock as per the Conversion Price, but not to exceed the conversion limitation set forth in Section 5(f) below.
	b.	Stock Certificates or DWAC. Upon the Holder submitting a Conversion Notice to the Company, the Company shall deliver to the Holder or Holder’s authorized designee, no later than 2 Trading Days after the Conversion Date, a certificate or certificates (which certificate(s) shall be free of restrictive legends and trading restrictions if the shares of Common Stock underlying the portion of the Note being converted are eligible under a resale exemption pursuant to Rule 144(b)(1)(ii) and Rule 144(d)(1)(ii) of the 1933 Act) representing the number of shares of Common Stock being acquired upon the conversion of this Note. In lieu of delivering physical certificates representing the shares of Common Stock issuable upon conversion of this Note, provided the Company’s transfer agent is participating in DTC’s FAST program, the Company shall instead use commercially reasonable efforts to cause its transfer agent to electronically transmit such shares issuable upon conversion to the Holder (or its designee), by crediting the account of the Holder’s (or such designee’s) broker with DTC through its DWAC program (provided that the same time periods herein as for stock certificates shall apply).
	c.	Charges and Expenses.

Holder shall pay all Transfer Agent fees incurred from the issuance of the Common Stock to Holder, as well as any and all other fees and charges required by the Transfer Agent as a condition to effectuate such issuance.
	d.	Delivery Timeline. Provided the Holder submits Conversion Notice to the Company, if the Company fails to deliver to the Holder such certificate or certificates (or shares through the DWAC program) pursuant to this Section (free of any restrictions on transfer or legends, if eligible) prior to 3 Trading Days after the Conversion Date, the Company shall pay to the Holder as liquidated damages an amount equal to $2,000 per day, until such certificate or certificates are delivered. The Company acknowledges that it would be extremely difficult or impracticable to determine the Holder’s actual damages and costs resulting from a failure to deliver the Common Stock and the inclusion herein of any such additional amounts are the agreed upon liquidated damages representing a reasonable estimate of those damages and costs. Such liquidated damages will be automatically added to the Principal Amount of the Note and tack back to the Effective Date for purposes of Rule 144.

4

	e.	Reservation of Underlying Securities. The Company covenants that it will at all times reserve and keep available for Holder, out of its authorized and unissued Common Stock solely for the purpose of issuance upon conversion of this Note, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holder, five times the number of shares of Common Stock as shall be issuable (taking into account the adjustments under this Section 5, but without regard to any ownership limitations contained herein) upon the conversion of this Note (consisting of the Principal Amount) to Common Stock (the “Required Reserve”). The Company covenants that all shares of Common Stock that shall be issuable will, upon issue, be duly authorized, validly issued, fully-paid, non-assessable and freely-tradable (if eligible). If the amount of shares on reserve in Holder’s name at the Company’s transfer agent for this Note shall drop below the Required Reserve, the Company will, within 2 Trading Days of notification from Holder, instruct the transfer agent to increase the number of shares so that the Required Reserve is met. In the event that the Company does not instruct the transfer agent to increase the number of shares so that the Required Reserve is met, the Holder will be allowed, if applicable, to provide this instruction as per the terms of the Irrevocable Transfer Agent Instructions attached to this Note.
	f.	Conversion Limitation. In the event the Holder submits a Conversion Notice to the Company that would, upon issuance of the requested shares, result in the Holder beneficially owning more than 9.99% of the then total outstanding shares of the Company, such Conversion Notice shall automatically be amended to reduce the number of requested shares such that that the issuance of amount of shares that would not result in the Holder beneficially owning more than 9.99% of the then total outstanding shares of the Company.
	g.	Conversion Delays. If the Company fails to deliver shares in accordance with the timeframe stated in Section 5(d) above, in addition to all other remedies available to the Holder, at any time prior to selling all of those shares, may rescind any portion of the particular conversion attributable to the unsold shares. The rescinded conversion amount will be returned to the Principal Sum with the rescinded conversion shares returned to the Company, under the expectation that any returned conversion amounts will tack back to the Effective Date.
	h.	Shorting and Hedging. Holder may not engage in any “shorting” or “hedging” transaction(s) in the Common Stock prior to conversion.
	i.	Conversion Right Unconditional. Upon the Holder providing the Company with a Conversion Notice, the Company’s obligations to deliver Common Stock as set forth in the Conversion Notice shall be absolute and unconditional, irrespective of any claim of setoff, counterclaim, recoupment, or alleged breach the Company may hold against the Holder.

Section 6. Defaults and Remedies.

Section 7. Representations and Warranties of Holder.

Holder hereby represents and warrants to the Company that:

	a.	Holder is an “accredited investor,” as such term is defined in Regulation D of the 1933 Act and will acquire the Securities for its own account and not with a view to a sale or distribution thereof as that term is used in Section 2(a)(11) of the 1933 Act, in a manner which would require registration under the 1933 Act or any state securities laws. Holder has such knowledge and experience in financial and business matters that such ▇▇▇▇▇▇ is capable of evaluating the merits and risks of the Securities. Holder can bear the economic risk of the Securities, has knowledge and experience in financial business matters and is capable of bearing and managing the risk of investment in the Securities. Holder recognizes that the Securities have not been registered under the 1933 Act, nor under the securities laws of any state and, therefore, cannot be resold unless the resale of the Securities is registered under the 1933 Act or unless an exemption from registration is available. ▇▇▇▇▇▇ has carefully considered and has, to the extent Holder believes such discussion necessary, discussed with its professional, legal, tax and financial advisors, the suitability of an investment in the Securities for its particular tax and financial situation and its advisers, if such advisors were deemed necessary, and has determined that the Securities are a suitable investment for it. Holder has not been offered the Securities by any form of general solicitation or advertising, including, but not limited to, advertisements, articles, notices or other communications published in any newspaper, magazine, or other similar media or television or radio broadcast or any seminar or meeting where, to Holders’ knowledge, those individuals that have attended have been invited by any such or similar means of general solicitation or advertising. ▇▇▇▇▇▇ has had an opportunity to ask questions of and receive satisfactory answers from the Company, or any person or persons acting on behalf of the Company, concerning the terms and conditions of the Securities and the Company, and all such questions have been answered to the full satisfaction of Holder. The Company has not supplied Holder any information regarding the Securities or an investment in the Securities other than as contained in this Agreement, and Holder is relying on its own investigation and evaluation of the Company and the Securities and not on any other information.
	b.	The Holder is duly organized, validly existing and in good standing under the laws of the state of its formation or incorporation and has all requisite corporate power and authority to carry on its business as now conducted. The Holder is duly qualified to transact business and is in good standing in each jurisdiction in which the failure to so qualify would have a material adverse effect on its business or properties.
	c.	All corporate action has been taken on the part of the Holder, its officers, directors and stockholders necessary for the authorization, execution and delivery of this Note. The Holder has taken all corporate action required to make all of the obligations of the Holder reflected in the provisions of this Note, valid and enforceable obligations.
	d.	The Holder acknowledges that each certificate or instrument representing Securities will be endorsed with the following legend (or a substantially similar legend), unless or until registered under the 1933 Act or exempt from registration:

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE TRANSFER IS MADE IN COMPLIANCE WITH RULE 144 PROMULGATED UNDER SUCH ACT OR THE COMPANY RECEIVES AN OPINION OF COUNSEL FOR THE HOLDER OF THESE SECURITIES WHICH IS REASONABLY SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

	a.	Payment of Expenses. The Company agrees to pay all reasonable charges and expenses, including attorneys’ fees and expenses, which may be incurred by the Holder in successfully enforcing this Note and/or collecting any amount due under this Note.
	b.	Assignment, Etc. The Holder may assign or transfer this Note and any Common Shares into which it may be converted from time to time, to any transferee at its sole discretion. This Note shall be binding upon the Company and its successors and shall inure to the benefit of the Holder and its successors and permitted assigns.
	c.	Amendments. This Note may not be modified or amended, or any of the provisions of this Note waived, except by written agreement of the Company and the Holder.
	d.	Piggyback Registration Rights. The Company shall include on the next registration statement that the Company files with the SEC (or on the subsequent registration statement if such registration statement is withdrawn) all shares issuable upon conversion of this Note.
	e.	Terms of Future Financings. So long as this Note is outstanding, upon any issuance by the Company or any of its subsidiaries of any convertible debt security (whether such debt begins with a convertible feature or such feature is added at a later date) with any term more favorable to the holder of such security or with a term in favor of the holder of such security that was not similarly provided to the Holder in this Note, then the Company shall notify the Holder of such additional or more favorable term and such term, at the Holder’s option, shall become a part of this Note and its supporting documentation. The types of terms contained in the other security that may be more favorable to the holder of such security include, but are not limited to, terms addressing conversion discounts, conversion look back periods, interest rates, and warrant coverage.
	f.	Governing Law; Jurisdiction.

	i.	Governing Law. This Note will be governed by, and construed and interpreted in accordance with, the laws of the state of Nevada without regard to any conflicts of laws or provisions thereof that would otherwise require the application of the law of any other jurisdiction.

	h.	Delivery of Process by the Holder to the Company. In the event of an action or proceeding by the Holder against the Company, and only by the Holder against the Company, service of copies of summons and/or complaint and/or any other process that may be served in any such action or proceeding may be made by the Holder via U.S. Mail, overnight delivery service such as FedEx or UPS, email, fax, or process server, or by mailing or otherwise delivering a copy of such process to the Company at its last known attorney as set forth in its most recent SEC filing.

9

	i.	Notices. Any notice required or permitted hereunder (including Conversion Notices) must be in writing and either personally served, sent by facsimile or email transmission, or sent by overnight courier. Notices will be deemed effectively delivered at the time of transmission if by facsimile or email, and if by overnight courier the business day after such notice is deposited with the courier service for delivery.
	j.	No Bad Actor. No officer or director of the Company would be disqualified under Rule 506(d) of the Securities Act of 1933, as amended, on the basis of being a “bad actor” as that term is established in the September 13, 2013 Small Entity Compliance Guide published by the SEC.
	k.	Usury. If it shall be found that any interest or other amount deemed interest due hereunder violates any applicable law governing usury, the applicable rate of interest due hereunder shall automatically be lowered to equal the maximum rate of interest permitted under applicable law. The Company covenants (to the extent that it may lawfully do so) that it will not seek to claim or take advantage of any law that would prohibit or forgive the Company from paying all or a portion of the principal, fees, liquidated damages or interest on
	l.	Right of First Refusal. From and after the date of this Note and at all times hereafter while the Note is outstanding, the Parties agree that, in the event that the Company receives any written or oral proposal (the “Proposal”) containing one or more offers to provide additional capital or equity or debt financing (the “Financing Amount”), the Company agrees that it shall provide a copy of all documents received relating to the Proposal together with a complete and accurate description of the Proposal to the Holder and all amendments, revisions, and supplements thereto (the “Proposal Documents”) no later than 3 business days from the receipt of the Proposal Documents. Following receipt of the Proposal Documents from the Company, the Holder shall have the right (the “Right of First Refusal”), but not the obligation, for a period of 5 business days thereafter (the “Exercise Period”), to invest, at similar or better terms to the Company, an amount equal to or greater than the Financing Amount, upon written notice to the Company that the Holder is exercising the Right of First Refusal provided hereby. In furtherance of the Right of First Refusal, the Company agrees that it will cooperate and assist the Holder in conducting a due diligence investigation of the Company and its corporate and financial affairs and promptly provide the Holder with information and documents that the Holder may reasonably request so as to allow the Holder to make an informed investment decision. However, the Company and the Holder agree that the Holder shall have no more than 5 business days from and after the expiration of the Exercise Period to exercise its Right of First Refusal hereunder. This Right of First Refusal shall extend to all purchases of debt held by, or assigned to or from, current stockholders, vendors, or creditors, all transactions under Sections 3(a)9 and/or 3(a)10 or the Securities Act of 1933, as amended, and all equity line-of-credit transactions.
	m.	Indemnification. As an original and independent obligation under this Agreement, the Holder shall (i) indemnify the Directors and Officers of the Company against all out-of-pocket costs, losses, expenses and liabilities of whatever kind resulting from the failure by any other Loan Party identified in the Use of Proceeds to make due and punctual payment of any of the Obligations or resulting from any of the Obligations being or becoming void, voidable, unenforceable or ineffective against any other Loan Party (including, but without limitation, all out-of-pocket legal and other costs, charges and expenses incurred by the Holder, in connection with preserving or enforcing, or attempting to preserve or enforce, its rights under this Agreement); and (ii) indemnify the Company of any such costs, losses, expenses and liabilities against any other Loan Party, or any other person or otherwise, resulting in the Use of Proceeds identified in this Agreement.
	n.	Non-Recourse Obligations. Notwithstanding anything to the contrary stated herein, ▇▇▇▇▇▇ agrees that for payment of this Note it will look solely to the conversion of stock, pursuant to Section 5 above, and no other assets of the Company shall be subject to levy, execution or other enforcement procedure for the satisfaction of the remedies of Holder, or for any payment required to be made under this Note.
