REPRESENTATIONS
AND WARRANTIES

 

3.1
Representations and Warranties of the Company. The Company hereby makes the following representations and warranties to
the Purchaser as of the date hereof and as of the Closing Date (unless such representation is made as of a specific date therein
in which case such representation and warranty shall be accurate as of such date):

 

(a)
Organization and Qualification. Each of the Company and the Company Sub is an entity duly incorporated, validly existing,
and in good standing under the laws of the jurisdiction of its incorporation, with the requisite power and authority to own and
use its properties and assets and to carry on its business as currently conducted.

 

(b)
Capitalization. The capitalization of the Company is properly reflected in all material respects by the SEC Filings as
of the date indicated in such filings.

 

(c)
Private Placement. Assuming the accuracy of the Purchaser’s representations and warranties set forth in Section
3.2, no registration under the Securities Act is required for the offer and sale of the Securities to the Purchaser as contemplated
hereby. The issuance and sale of the Securities hereunder does not contravene the rules and regulations of the Trading Market
applicable to the Company.

 

(d)
SEC Filings. The documents (the “SEC Filings”) that have been filed by the Company with the SEC do not
(as amended and supplemented) contain a material misstatement of fact or does not omit to state any material fact necessary in

by the Exchange Act.

 

(e)
Financing Needs. The Company requires immediate financing through the offering of the securities under this Agreement to
acquire additional funds for certain working capital and general corporate purposes that are due and payable within 30 days and
if not paid would cause a material adverse effect to the Company, including the payment of payroll and other cash compensation
and insurance. Accordingly, the purpose of the offering under this Agreement is different than the planned use of proceeds from
the public offering described in the Registration Statement.

 

3.2
Representations and Warranties of the Purchaser. The Purchaser hereby represents and warrants as of the date hereof and
as of the Closing Date to the Company as follows (unless as of a specific date therein):

 

(a)
Organization; Authority.

 

(i)
The Purchaser is either an individual or an entity that is duly incorporated or formed, validly existing, and in good standing
under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability
company, or similar power and authority to enter into and to consummate the transaction contemplated by the Transaction Documents
and otherwise to carry out its obligations hereunder and thereunder.

 

(ii)
The execution and delivery of the Transaction Documents and performance by the Purchaser of the transaction contemplated by the
Transaction Documents have been duly authorized by all necessary corporate, partnership, limited liability company, or similar
action, as applicable, on the part of the Purchaser.

(iii)
Each Transaction Document to which it is a party has been duly executed by the Purchaser, and when delivered by the Purchaser
in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Purchaser, enforceable against
it in accordance with its terms, except: (a) as limited by general equitable principles and applicable bankruptcy, insolvency,
reorganization, moratorium, and other laws of general application affecting enforcement of creditors’ rights generally;
(b) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies; and
(c) insofar as indemnification and contribution provisions may be limited by applicable law.

 

(b)
Own Account. The Purchaser understands that the Securities are “restricted securities” and have not been registered

and not with a view to or for distributing or reselling the Securities or any part thereof in violation of the Securities Act
or any applicable state securities law, has no present intention of distributing any of such Securities in violation of the Securities
Act or any applicable state securities law and has no direct or indirect arrangement or understandings with any other person to
distribute or regarding the distribution of such Securities in violation of the Securities Act or any applicable state securities
law (this representation and warranty not limiting the Purchaser’s right to sell the Securities in compliance with applicable
federal and state securities laws). The Purchaser is acquiring the Securities hereunder in the ordinary course of its business
or investment strategy.

 

(c)
Purchaser Status. At the time the Purchaser was offered the Securities, it was, and as of the date hereof it is an “accredited
investor” as defined in Rule 501 under the Securities Act; or (ii) a Non U.S. Person within the meaning of Regulation S
under the Securities Act. The information provided by the Purchaser to the Company in the Certificate of Accredited Investor Status
is true and correct.

 

(d)
Experience of the Purchaser. The Purchaser, either alone or together with its representatives, has such knowledge, sophistication
and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Securities, and has so evaluated the merits and risks of such investment. The Purchaser is able to bear the economic risk
of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

 

(e)
No Short Sales. The Purchaser shall not directly or indirectly, nor shall any Person acting on behalf of or pursuant to
any understanding with the Purchaser, execute any Short Sales of the securities of the Company while the Note is outstanding.

 

(f)
Disclosure.

 

(i)
The Purchaser acknowledges and agrees that the information provided and available to the Purchaser at the time that this Agreement
is executed and delivered (including, but not limited to the SEC Filings) (the “Execution Date Information”)
may not include all of the material information that would be provided to a purchaser of securities in an offering of securities
that is registered under the Securities Act and included in a prospectus that is required to be delivered in accordance with Section
5 of the Securities Act. Additionally, the Purchaser acknowledges that it will not have the benefits of the disclosures and the
civil remedies that flow from an offering registered under the Securities Act.

 

(ii)
The Purchaser agrees that it has had an opportunity to conduct its due diligence on the investment and in connection therewith:

the Company and any other matters relating directly or indirectly to the purchase of the Securities by the Purchaser; (b) ask
questions of, and receive answers from, the executives of the Company concerning the terms and conditions of investment in the
Securities and to obtain such additional information as may have been necessary to verify the accuracy of any information that
may have been provided to the Purchaser; and (c) acknowledges that the only information the Purchaser relied upon is information
or documentation that was provided expressly by the Company to the Purchaser for such purposes. The Purchaser acknowledges that
it has had information about the Company based on its investments in the Company and by reference to the SEC Filings other than
the Registration Statement.

 

    	 	4	 

    	 

    

 

(iii)
The Purchaser and/or Purchaser’s advisor acknowledges that it has received and reviewed the SEC Filings, including the summary
of risks contained in the “Risk Factors” sections in such documents and Schedule B and certain matters regarding
the use of proceeds set forth in Section 4.3 and had access to or been furnished with sufficient facts and information
to evaluate an investment in the Company and a reasonable opportunity to ask questions of and receive answers from a person or
persons acting on behalf of the Company concerning the Company and all such questions have been answered to the full satisfaction
of the Purchaser. The Purchaser acknowledges that in addition to the risks summarized in Schedule B, there is a risk that the
public offering contemplated by the Registration Statement will not be consummated, that the Company may abandon the Registration
Statement for any reason, including without limitation, market conditions or any decision by the lead underwriter described therein,
which decision is in the sole and absolute discretion of such underwriter. The Purchaser acknowledges it would purchase the securities
to be issued by the Company under this Agreement even if the Company does not complete the public offering described in the Registration
Statement.

 

(g)
Solicitation. The Purchaser acknowledges that it did not become interested in the purchase of securities to be issued by
the Company through any general solicitation or advertisement, including the Registration Statement. The Purchaser acknowledges
that it has a substantive, preexisting personal investment relationship with the Company based on its ownership of Common Stock
and warrants and several investments by the Purchaser. The Purchaser was solicited by the Company via direct solicitation by the
Chief Executive Officer of the Company (the “CEO”), who has a personal relationship with the Purchaser, and
a determination by the CEO that the Purchaser has the means and is likely to continue its investment interest in the Company.
The Purchaser acknowledges that it was solicited by the Company for interest in the securities to be issued by the Company under
this Agreement and that the Purchaser was not identified or contacted through the marketing of the public offering under the Registration
Statement and the Purchaser did not independently contact the Company as a result of any solicitation by any broker dealer, including
the lead underwriter specified in the Registration Statement.

 

The
Company acknowledges and agrees that the representations contained in Section 3.2 shall not modify, amend or affect the
Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations
and warranties contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection
with this Agreement or the consummation of the transaction contemplated hereby.

Certain
Additional Risk Factors

 

In
addition to the risk factors summarized in the Company’s SEC Filings, you should consider the following:

 

An
investment in the Securities involves a high degree of risk. You should carefully consider the risks summarized in the Company’s
SEC Filings, together with all of the other information provided to you in this Agreement, before making an investment decision.
If any of the following risks actually occur, our business, financial condition or results of operations could suffer. In that
case, the trading price of our shares of Common Stock could decline, and you may lose all or part of your investment. You should
read the section entitled “Forward-Looking Statements” included in our SEC Filings for a discussion of what types
of statements are forward-looking statements, as well as the significance of such statements.

 

The
terms of this transaction and the purchase price for the Securities were not independently valued and may not be indicative of
the future price of Common Stock. 

 

Our
board of directors determined the terms and conditions of this transaction, including the purchase price of the Securities. The
purchase price of the Securities was not necessarily determined to be equal to the market price of the Common Stock on the OTCQB
or the fair value of the Company. If you purchase the Securities, you may not be able to sell any of the Securities at or above
the purchase price. The trading price of the Common Stock will be determined by the marketplace and will be influenced by many
factors outside of the Company’s control, prevailing interest rates, investor perceptions, securities analyst research reports
and general industry, geopolitical, and economic conditions. Publicly traded stocks, including stocks of pharmaceutical and nutraceutical
companies, often experience substantial market price volatility. These market fluctuations might not be related to the operating
performance of particular companies whose shares are traded. Accordingly, we cannot assure you that if you purchase the Securities
you will later be able to sell any of the Securities at or above the purchase price.

 

The
Securities are “Restricted Securities” under the Securities Act and there is no assurance they will be registered.

 

The
Securities will be restricted securities under United States federal and applicable state securities laws. The Securities will
be restricted securities unless and until the Securities are registered. Restricted securities may not be transferred, sold or
otherwise disposed of in the United States, except as permitted under United States federal and state securities laws, pursuant
to registration or an exemption therefrom. You should be prepared to hold the Securities for an indefinite period.

 

The
Securities may not be sold unless, at the time of such intended sale, there is a current registration statement covering the resale
of the securities or there exists an exemption from registration under the Securities Act, and such securities have been registered,
qualified, or deemed to be exempt under applicable securities or “blue sky” laws in the state of residence of the
seller or in the state where sales are being affected.

 

If
there is not an effective registration statement covering the resale of the Securities, you will be precluded from disposing of
such shares unless such shares may become eligible to be disposed of under the exemptions provided by Rule 144 under the Securities
Act without restriction. If the Securities are not registered for resale under the Securities Act, or exempt therefrom, and registered
or qualified under applicable securities or “blue sky” laws, or deemed exempt therefrom, the value of the Securities
will be greatly reduced.

 

Insufficient
Capital

 

There
can be no assurance or guarantee that the Company will raise sufficient capital, through this transaction or otherwise, to meet
the Company’s business objectives or fund its operations. The audited financial statements of the Company include a going
concern qualification and the Company has significant liquidity issues, including that described in the SEC Filings. There can
be no assurance that other obligations that are necessary for the Company will not be incurred or that the budgeted expenditures
will not be subject to any material increase.

TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT TO SUCH SECURITIES
UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH
REGISTRATION IS NOT REQUIRED.

to the Holder on the outstanding principal amount in accordance with the provisions hereof. Notwithstanding the foregoing, repayment

Article
III. CONVERSION

 

3.1
Method of Conversion. At any time while this Note is outstanding, this Note shall be convertible, in whole or in part,
into shares (the “Conversion Shares”) of Common Stock at the Conversion Price (as defined below), at the option
of the Holder, at any time and from time to time. The Holder shall effect conversions by delivering to the Company a Notice of
Conversion, the form of which is attached hereto as Exhibit I (each, a “Notice of Conversion”),
specifying therein the outstanding principal amount of this Note, plus at the Holder’s option, any accrued and unpaid interest
thereon, to be converted and the date on which such conversion shall be effected (such date, a “Conversion Date”).
If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion
is deemed delivered hereunder.

 

3.2
Conversion Price. The conversion price (the “Conversion Price”) per share of Common Stock in effect
on any Conversion Date shall be equal to $____, subject to adjustment as provided below.

 

(a)
Adjustment Upon Stock Split. If at any time while this Note is outstanding, the Company: (i) subdivides outstanding shares
of Common Stock into a larger number of shares, (ii) combines (including by way of a reverse stock split) outstanding shares of
Common Stock into a smaller number of shares, or (iii) issues, in the event of a reclassification of shares of the Common Stock,
any shares of capital stock of the Company, then the Conversion Price shall be equitably adjusted. Any adjustment made pursuant
to this Section 3.2(a) shall become effective immediately after the effective date of the subdivision, combination, or
re-classification.

 

    	 	2	 

    	 

    

 

3.3
Mechanics of Conversion.

 

(a)
Conversion Shares Issuable Upon Conversion. The number of Conversion Shares issuable upon a conversion hereunder shall
be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Note to be converted, plus at
the Holder’s option, any accrued and unpaid interest thereon to be converted, by (y) the Conversion Price.

 

(b)
No Fractional Shares Upon Conversion. No fractional shares shall be issued upon the conversion of this Note. As to any
fraction of a share that the Holder would otherwise be entitled to upon such conversion, the Company shall at its election, either
pay a cash adjustment in an amount equal to such fraction multiplied by the Conversion Price or round up to the next whole share.

 

(c)
Delivery of Certificate Upon Conversion. On the Conversion Date, or promptly thereafter, the Company shall issue and deliver
or cause to be issued and delivered a certificate or certificates representing the Conversion Shares.

 

(d)
Surrender of Note Upon Conversion. To effect conversions hereunder, the Holder shall not be required to physically surrender
this Note to the Company unless the entire outstanding principal amount of this Note, plus all accrued and unpaid interest thereon,
is to be converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Note and
accrued and unpaid interest thereon, in an amount equal to the applicable conversion, and all rights with respect to the portion
of this Note being so converted shall forthwith terminate except the right to receive the Conversion Shares, as provided herein.
The Holder and the Company shall maintain records showing the principal and interest amount(s) converted and the date of such
conversion(s). In the event of any dispute or discrepancy, the records of the Company shall be controlling and determinative in
the absence of manifest error. The Holder, and any assignee by acceptance of this Note, acknowledge and agree that, by reason
of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted principal amount
of this Note may be less than the amount stated on the face hereof.

 

(e)
Authorized Shares. The Company shall reserve from its authorized and unissued Common Stock a sufficient number of shares,
free from preemptive rights, to provide for the issuance of Common Stock upon the full conversion of this Note. The Company represents
that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable.

 

Article
IV. REPAYMENT

 

4.1
Prepayment. Notwithstanding anything to the contrary contained in this Note, the Company may prepay the amounts outstanding

(a)
At any time while this Note is outstanding, the Company shall have the right, exercisable on not less than five (5) trading days
prior written notice (a “Prepayment Notice”) to the Holder, to prepay the Note (outstanding principal and accrued
interest), in whole or in part, without penalty.

 

(b)
Notwithstanding the Prepayment Notice, upon receipt of such notice and prior to the prepayment date (the “Prepayment
Date”) specified by the Company in the Prepayment Notice, the Holder may elect to convert any outstanding portion of
the Note, including any accrued interest, by submitting a Notice of Conversion to the Company as set forth in this Note.

 

4.2
Repayment Amortization Upon Maturity. If this Note, or any portion thereof, remains outstanding upon the Maturity Date,
then repayment of the unpaid and unconverted principal amount of this Note, shall be amortized over the following thirty-six (36)
months, with monthly payments (each, an “Amortization Payment”) to be made on or prior to the 10th
calendar day of each month, beginning on the first such date after the Maturity Date. Until this Note is repaid or converted in
full, the Holder shall continue to have all rights as a holder of this Note.

without the Holder’s written consent, sell, lease, or otherwise dispose of all or substantially all of its assets outside
the ordinary course of business unless the proceeds of any disposition of its assets shall be used to repay this Note.

 

5.2
Non-Circumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate or
Articles of Incorporation or Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement,

Holder of this Warrant may exercise, in whole or in part, the purchase rights evidenced by this Warrant during the period commencing

    	 	2	 

    	 

    

 

(b) Conditions
to Exercise of the Warrant.

 

(i) Notwithstanding
the provisions of any provision of this Warrant, including Section 1.3, the exercise of this Warrant is contingent upon
the Company’s satisfaction that the issuance of the Shares for which this Warrant is being exercised is exempt from the
requirements of the Securities Act and all applicable state securities laws or the Shares are duly registered under the Securities
Act. The Holder of this Warrant agrees to execute any and all documents deemed necessary by the Company to effect the exercise
of this Warrant.

 

(ii) Notwithstanding
anything to the contrary contained herein, the number of Shares that may be acquired by the Holder upon any exercise of this Warrant
(or otherwise in respect hereof) shall be limited to the extent necessary to insure that, following such exercise (or other issuance),
the total number of shares of Common Stock then beneficially owned by such Holder and its Affiliates and any other Persons whose
beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange
Act (the “Beneficial Ownership”, does not exceed 4.99% of the total number of issued and outstanding
shares of Common Stock (including for such purpose the shares of Common Stock issuable upon such exercise) (the “Maximum
Percentage”). For the avoidance of doubt, except as otherwise provided herein in connection with a transaction described
in Section 4.3 (a “Fundamental Transaction”), this Warrant may not be exercised in whole or in part
if the Holder’s Beneficial Ownership (as calculated herein) exceeds the Maximum Percentage prior to such exercise. For such
purposes, “Beneficial Ownership” shall be determined in accordance with Section 13(d) of the Exchange
Act and the rules and regulations promulgated thereunder. This provision shall not restrict the number of shares of Common Stock
which a Holder may receive or beneficially own in order to determine the amount of securities or other consideration that such
Holder may receive in the event of a Fundamental Transaction of this Warrant or under any other provision of Section 4.
This restriction may not be waived except by the Holder providing a notice to the Company as provided herein. For any reason at
any time, upon the written or oral request of the Holder, the Company shall promptly confirm in writing (which may be by electronic
mail) to the Holder the number of shares of Common Stock then outstanding. To the extent that the limitation contained in this
Section 1.3(b)(ii) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned
by such Holder together with any Affiliates) and of which a portion of this Warrant is exercisable shall be in the sole discretion
of a Holder, and the submission of a Notice of Exercise shall be deemed to be each Holder’s determination of whether this
Warrant is exercisable (in relation to other securities owned by such Holder together with any Affiliates) and of which portion
of this Warrant is exercisable, in each case subject to such aggregate percentage limitation, and the Company shall have no obligation
to verify or confirm the accuracy of such determination other than its obligation in this Section 1.3(b)(ii) above to,
upon the Holder’s request, confirm in writing to the Holder the number of shares of Common Stock then outstanding. Notwithstanding
any provision of this Section 1.3(b)(ii) to the contrary, the limitations on the exercise of this Warrant under this Section
1.3(b)(ii) shall not be applicable from and after the date that is 61 days after the date that the Holder provides written
notice to the Company that the Holder elects to have Beneficial Ownership of the Company’s Common Stock in excess of the
Maximum Percentage, in which case such Holder shall have the right to exercise this Warrant without the limitations of this Section
1.3(b)(ii); provided, that the limitations of this Section 1.3(b)(ii) shall again be applicable to any assignee
of this Warrant until 61 days after such assignee provides such notice to the Company.

 

    	 	3	 

    	 

    

  

1.4. Issuance
of Shares. In the event the purchase rights evidenced by this Warrant are exercised in whole or in part, one or more certificates
for the purchased Shares shall be issued as soon as practicable thereafter to the Holder.

 

1.5. Partial
Exercise. If this Warrant shall have been exercised only in part, then the Company shall, at the time of delivery of the certificate
or certificates for the Shares purchased upon such exercise, also deliver to the Holder a new Warrant evidencing the remaining
outstanding unexercised balance of Shares purchasable hereunder.

 

1.6. Cancellation.
Notwithstanding anything in this Warrant to the contrary, this Warrant shall be cancelled, and shall not be exercisable, if it
is not exercised before the expiration of the Exercise Period.

 

2. TRANSFER
RESTRICTIONS

 

2.1. Transfer.
This Warrant and the Shares issuable upon exercise hereof are “restricted securities” as such term is defined by the
rules and regulations promulgated under the Securities Act. This Warrant and the Shares issuable upon exercise hereof may only
be disposed of in compliance with state and federal securities laws. In connection with any transfer of this Warrant or the Shares
issuable upon exercise hereof, other than pursuant to an effective registration statement or Rule 144, to the Company or to an
Affiliate of a Holder, the Company may require the transferor to provide to the Company an opinion of counsel selected by the
transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory
to the Company, to the effect that such transfer does not require registration of the transferred Warrant or Shares under the
Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Warrant
and the Agreement and shall have the rights and obligations of a Holder under this Warrant and the Agreement.

 

2.2. Legend.

 

(a) The
Holder agrees to the imprinting of a legend on any of the Shares issuable upon exercise hereof in the following form:

 

THIS
SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE
UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY,
MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH
APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF
WHICH SHALL BE REASONABLY ACCEPTABLE TO THE CORPORATION. THIS SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT
WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED INVESTOR” AS DEFINED
IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

 

    	 	4	 

    	 

    

 

(b) Notwithstanding
the foregoing, certificates evidencing this Warrant or the Shares issuable upon exercise hereof shall not contain any legend (including
the legend set forth above), (i) while a registration statement covering the resale of such security is effective under the Securities
Act, (ii) following any sale of this Warrant or such Shares issuable upon exercise hereof pursuant to Rule 144, (iii) if this
Warrant or such Shares issuable upon exercise hereof are eligible for sale under Rule 144, without the requirement for the Company
to be in compliance with the current public information required under Rule 144 as to this Warrant or such Shares issuable upon
exercise hereof and without volume or manner-of-sale restrictions, or (iv) if such legend is not required under applicable requirements
of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission).

 

2.3. Sale.
The Holder agrees that the Holder will sell this Warrant or any Shares issuable upon exercise hereof only pursuant to either:
(i) the registration requirements of the Securities Act, including any applicable prospectus delivery requirements; or (ii) an
exemption therefrom, and that if this Warrant or any Shares issuable upon exercise hereof are sold pursuant to any such effective
registration statement, they will be sold in compliance with the plan of distribution set forth therein, and acknowledges that
the removal of the restrictive legend from certificates representing the Shares or this Warrant is predicated upon the Company’s
reliance upon this understanding.

 

3. Fractional
Shares

 

Notwithstanding
that the number of Shares purchasable upon the exercise of this Warrant may have been adjusted pursuant to the terms hereof, the
Company shall nonetheless not be required to issue fractions of Shares upon exercise of this Warrant or to distribute certificates
that evidence fractional shares, provided that in lieu of any fraction shares, the Company shall make a cash payment to the Holder
in an amount equal to the fair market value (as determined by the Board of Directors of the Company in its reasonable good faith)
of such fractional share.

 

4. ANTIDILUTION
PROVISIONS

 

4.1. Stock
Splits and Combinations. If the Company shall at any time subdivide or combine its outstanding shares of Common Stock, this
Warrant shall, after that subdivision or combination, evidence the right to purchase the number of shares of Common Stock that
would have been issuable as a result of that change with respect to the shares of Common Stock which were purchasable under this
Warrant immediately before that subdivision or combination. If the Company shall at any time subdivide the outstanding shares
of Common Stock, the Warrant Exercise Price then in effect immediately before that subdivision shall be proportionately decreased,

    	 	5	 

    	 

    

 

4.2. Reclassification,
Exchange and Substitution. If the Common Stock issuable upon exercise of this Warrant shall be changed into the same or a
different number of shares of any other class or classes of stock, whether by capital reorganization, reclassification, or otherwise
(other than a subdivision or combination of shares provided for above), the Holder of this Warrant shall, on its exercise, be
entitled to purchase for the same aggregate consideration, in lieu of the Common Stock that the Holder would have been entitled
to purchase but for such change, a number of shares of such other class or classes of stock equivalent to the number of shares
of Common Stock that would have been subject to purchase by the Holder on exercise of this Warrant immediately before that change.

 

4.3. Reorganizations,
Mergers, Consolidations or Sale of Assets. If at any time there shall be a capital reorganization of the Company’s Common
Stock (other than a combination, reclassification, exchange, or subdivision of shares provided for elsewhere above) or merger
or consolidation of the Company with or into another entity, or the sale of the Company’s properties and assets as, or substantially
as, an entirety to any other person or entity, then, as a part of such reorganization, merger, consolidation or sale, lawful provision
shall be made so that the Holder of this Warrant shall thereafter be entitled to receive upon exercise of this Warrant, during
the period specified in this Warrant and upon payment of the Warrant Exercise Price then in effect, the number of shares of Common
Stock or other securities or property of the Company, or of the successor entity resulting from such merger or consolidation,
to which a holder of the Common Stock deliverable upon exercise of this Warrant would have been entitled in such capital reorganization,
merger, or consolidation or sale if this Warrant had been exercised immediately before that capital reorganization, merger, consolidation,
or sale. In any such case, appropriate adjustment (as determined in good faith by the Company’s Board of Directors) shall
be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder of this Warrant
after the reorganization, merger, consolidation, or sale to the end that the provisions of this Warrant (including adjustment
of the Warrant Exercise Price then in effect and number of Shares purchasable upon exercise of this Warrant) shall be applicable
after that event, as near as reasonably may be, in relation to any shares or other property deliverable after that event upon
exercise of this Warrant. The Company shall, within thirty (30) days after making such adjustment, give written notice (by first
class mail, postage prepaid) to the Holder of this Warrant at the address of the Holder shown on the Company’s books. That
notice shall set forth, in reasonable detail, the event requiring the adjustment and the method by which the adjustment was calculated,
and specify the Warrant Exercise Price then in effect after the adjustment and the increased or decreased number of Shares or
the other shares or property purchasable upon exercise of this Warrant. When appropriate, that notice may be given in advance
and include as part of the notice required under other provisions of this Warrant.

5. Reservation
of Stock Issuable Upon Exercise

 

The
Company shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock solely for the
purpose of effecting the exercise of this Warrant such number of its shares of Common Stock as shall from time to time be sufficient
to effect the exercise of this Warrant and if at any time the number of authorized but unissued shares of Common Stock shall not
be sufficient to effect the exercise of this Warrant, in addition to such other remedies as shall be available to the Holder of
this Warrant, the Company will use its best efforts to take such corporate action as may, in the opinion of its counsel, be necessary
to increase its authorized but un-issued shares of Common Stock to such number of shares as shall be sufficient for such purposes.

 

6. RIGHTS
PRIOR TO EXERCISE OF WARRANT

 

6.1. This
Warrant does not entitle the Holder to any of the rights of a stockholder of the Company, including without limitation, the right
to receive dividends or other distributions, to exercise any preemptive rights, to vote, or to consent or to receive notice as
a stockholder of the Company. If, however, at any time prior to the termination of this Warrant and prior to its exercise, any
of the following events shall occur:

 

(a) the
Company shall declare any dividend payable in any securities upon its shares of Common Stock or make any distribution (other than
a regular cash dividend) to the Holders of its shares of Common Stock; or

 

(b) the
Company shall offer to the holders of its shares of Common Stock any additional Warrant of Common Stock or securities convertible
into or exchangeable for shares of Common Stock or any right to subscribe for or purchase any thereof; or

 

(c) a
dissolution, liquidation or winding up of the Company (other than in connection with a consolidation, merger, sale, transfer or
lease of all or substantially all of its property, assets and business as an entirety) shall be proposed and action by the Company
with respect thereto has been approved by the Company’s Board of Directors;

 

then
in any one or more of said events the Company shall give notice in writing of such event to the Holder at the last address of
the Holder as it shall appear on the Company’s records at least twenty (20) days prior to the date fixed as a record date
or the date of closing the transfer books for the determination of the stockholders entitled to such dividends, distribution,
or subscription rights, or for the determination of stockholders entitled to vote on such proposed dissolution, liquidation or
winding up. Such notice shall specify such record date or the date of closing the transfer books, as the case may be. Failure
to publish, mail or receive such notice or any defect therein or in the publication or mailing thereof shall not affect the validity
of any action taken in connection with such dividend, distribution or subscription rights, or such proposed dissolution, liquidation
or winding up. Each person in whose name any certificate for shares of Common Stock is to be issued shall for all purposes be
deemed to have become the holder of record of such shares on the date on which this instrument was surrendered and payment of
the Warrant Exercise Price was made, irrespective of the date of delivery of such stock certificate, except that, if the date
of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to
have become the holder of such shares of Common Stock at the close of business on the next succeeding date on which the stock
transfer books are open.

ARTICLE

REPRESENTATIONS
AND WARRANTIES

 

3.1
Representations and Warranties of the Company. The Company hereby makes the following representations and warranties to
the Purchaser as of the date hereof and as of the Closing Date (unless such representation is made as of a specific date therein
in which case such representation and warranty shall be accurate as of such date):

 

(a)
Organization and Qualification. Each of the Company and the Company Sub is an entity duly incorporated, validly existing,
and in good standing under the laws of the jurisdiction of its incorporation, with the requisite power and authority to own and
use its properties and assets and to carry on its business as currently conducted.

 

(b)
Capitalization. The capitalization of the Company is properly reflected in all material respects by the SEC Filings as
of the date indicated in such filings.

 

(c)
Private Placement. Assuming the accuracy of the Purchaser’s representations and warranties set forth in Section
3.2, no registration under the Securities Act is required for the offer and sale of the Note to the Purchaser as contemplated
hereby. The issuance and sale of the Note hereunder does not contravene the rules and regulations of the Trading Market applicable
to the Company.

 

(d)
SEC Filings. The documents (the “SEC Filings”) that have been filed by the Company with the SEC do not
(as amended and supplemented) contain a material misstatement of fact or does not omit to state any material fact necessary in
order to make the statements made therein, in light of the circumstances under which they were made, not misleading, as interpreted
by the Exchange Act.

 

(e)
Financing Needs. The Company requires immediate financing through the offering of the securities under this Agreement to
acquire additional funds for certain working capital and general corporate purposes that are due and payable within 30 days and
if not paid would cause a material adverse effect to the Company, including the payment of payroll and other cash compensation
and insurance. Accordingly, the purpose of the offering under this Agreement is different than the planned use of proceeds from
the public offering described in the Registration Statement.

 

3.2
Representations and Warranties of the Purchaser. The Purchaser hereby represents and warrants as of the date hereof and
as of the Closing Date to the Company as follows (unless as of a specific date therein):

 

(a)
Organization; Authority.

 

(i)
The Purchaser is either an individual or an entity that is duly incorporated or formed, validly existing, and in good standing
under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited liability
company, or similar power and authority to enter into and to consummate the transaction contemplated by the Transaction Documents
and otherwise to carry out its obligations hereunder and thereunder.

 

(ii)
The execution and delivery of the Transaction Documents and performance by the Purchaser of the transaction contemplated by the
Transaction Documents have been duly authorized by all necessary corporate, partnership, limited liability company, or similar
action, as applicable, on the part of the Purchaser.

 

(iii)
Each Transaction Document to which it is a party has been duly executed by the Purchaser, and when delivered by the Purchaser
in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Purchaser, enforceable against
it in accordance with its terms, except: (a) as limited by general equitable principles and applicable bankruptcy, insolvency,
reorganization, moratorium, and other laws of general application affecting enforcement of creditors’ rights generally;
(b) as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies; and
(c) insofar as indemnification and contribution provisions may be limited by applicable law.

 

    	3

    	 

    

 

(b)
Own Account. The Purchaser understands that the Securities are “restricted securities” and have not been registered
under the Securities Act or any applicable state securities law and is acquiring the Securities as principal for its own account
and not with a view to or for distributing or reselling the Securities or any part thereof in violation of the Securities Act
or any applicable state securities law, has no present intention of distributing any of such Securities in violation of the Securities
Act or any applicable state securities law and has no direct or indirect arrangement or understandings with any other person to
distribute or regarding the distribution of such Securities in violation of the Securities Act or any applicable state securities
law (this representation and warranty not limiting the Purchaser’s right to sell the Securities in compliance with applicable
federal and state securities laws). The Purchaser is acquiring the Securities hereunder in the ordinary course of its business
or investment strategy.

 

(c)
Purchaser Status. At the time the Purchaser was offered the Securities, it was, and as of the date hereof it is an “accredited
investor” as defined in Rule 501 under the Securities Act; or (ii) a Non U.S. Person within the meaning of Regulation S
under the Securities Act. The information provided by the Purchaser to the Company in the Certificate of Accredited Investor Status
is true and correct.

 

(d)
Experience of the Purchaser. The Purchaser, either alone or together with its representatives, has such knowledge, sophistication
and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Securities, and has so evaluated the merits and risks of such investment. The Purchaser is able to bear the economic risk
of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

 

(e)
No Short Sales. The Purchaser shall not directly or indirectly, nor shall any Person acting on behalf of or pursuant to
any understanding with the Purchaser, execute any Short Sales of the securities of the Company while the Note is outstanding.

 

[The
following provisions of subsection (f) and (g) are included in the form of purchase agreement for the issuance by the Company
of convertible promissory notes similar to this Note but are not effective in this Agreement and shall be deemed mute in this
Agreement.]

 

(f)
Disclosure.

 

(i)
The Purchaser acknowledges and agrees that the information provided and available to the Purchaser at the time that this Agreement
is executed and delivered (including, but not limited to the SEC Filings) (the “Execution Date Information”)
may not include all of the material information that would be provided to a purchaser of securities in an offering of securities
that is registered under the Securities Act and included in a prospectus that is required to be delivered in accordance with Section
5 of the Securities Act. Additionally, the Purchaser acknowledges that it will not have the benefits of the disclosures and the
civil remedies that flow from an offering registered under the Securities Act.

 

(ii)
The Purchaser agrees that it has had an opportunity to conduct its due diligence on the investment and in connection therewith:
(a) obtain additional information concerning investment in the Securities, including without limitation, information concerning
the Company and any other matters relating directly or indirectly to the purchase of the Securities by the Purchaser; (b) ask
questions of, and receive answers from, the executives of the Company concerning the terms and conditions of investment in the
Securities and to obtain such additional information as may have been necessary to verify the accuracy of any information that
may have been provided to the Purchaser; and (c) acknowledges that the only information the Purchaser relied upon is information
or documentation that was provided expressly by the Company to the Purchaser for such purposes. The Purchaser acknowledges that
it has had information about the Company based on its investments in the Company and by reference to the SEC Filings other than
the Registration Statement.

 

    	4

    	 

    

 

(iii)
The Purchaser and/or Purchaser’s advisor acknowledges that it has received and reviewed the SEC Filings, including the summary
of risks contained in the “Risk Factors” sections in such documents and Schedule B and certain matters regarding
the use of proceeds set forth in Section 4.3 and had access to or been furnished with sufficient facts and information
to evaluate an investment in the Company and a reasonable opportunity to ask questions of and receive answers from a person or
persons acting on behalf of the Company concerning the Company and all such questions have been answered to the full satisfaction
of the Purchaser. The Purchaser acknowledges that in addition to the risks summarized in Schedule B, there is a risk that the
public offering contemplated by the Registration Statement will not be consummated, that the Company may abandon the Registration
Statement for any reason, including without limitation, market conditions or any decision by the lead underwriter described therein,
which decision is in the sole and absolute discretion of such underwriter. The Purchaser acknowledges it would purchase the securities
to be issued by the Company under this Agreement even if the Company does not complete the public offering described in the Registration
Statement.

 

(g)
Solicitation. The Purchaser acknowledges that it did not become interested in the purchase of securities to be issued by
the Company through any general solicitation or advertisement, including the Registration Statement. The Purchaser acknowledges
that it has a substantive, preexisting personal investment relationship with the Company based on its ownership of Common Stock
and warrants and several investments by the Purchaser. The Purchaser was solicited by the Company via direct solicitation by the
Chief Executive Officer of the Company (the “CEO”), who has a personal relationship with the Purchaser, and
a determination by the CEO that the Purchaser has the means and is likely to continue its investment interest in the Company.
The Purchaser acknowledges that it was solicited by the Company for interest in the securities to be issued by the Company under
this Agreement and that the Purchaser was not identified or contacted through the marketing of the public offering under the Registration
Statement and the Purchaser did not independently contact the Company as a result of any solicitation by any broker dealer, including
the lead underwriter specified in the Registration Statement.

 

The
Company acknowledges and agrees that the representations contained in Section 3.2 shall not modify, amend or affect the
Purchaser’s right to rely on the Company’s representations and warranties contained in this Agreement or any representations
and warranties contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection
with this Agreement or the consummation of the transaction contemplated hereby.

 

ARTICLE
IV

OTHER
AGREEMENTS OF THE PARTIES

 

4.1
Transfer Restrictions.

 

(a)
The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of
any of the Securities other than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate
of the Purchaser, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the
transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory
to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities
Act.

 

    	5

    	 

    

 

(b)
Legend on Share Certificates. The Purchaser agrees to the imprinting, so long as is required by this Section 4.1,
of a legend on any of the certificates representing the Securities in the following form:

 

THIS
SECURITY HAS NOT BEEN REGISTERED UNDER EITHER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR THE
SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, OFFERED FOR SALE, TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE
OF AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT TO SUCH SECURITIES UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES
LAWS OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

 

(c)
The legends set forth in Section 4.1(b) shall, to the fullest extent permitted, be removed (i) while a registration statement
covering the resale of such security is effective under the Securities Act, (ii) following any sale of the Securities pursuant

and pronouncements issued by the staff of the SEC).

 

(d)
The Purchaser agrees that it will sell any Securities only pursuant to either: (i) the registration requirements of the Securities

reasonably satisfactory to the Company of such loss, theft, or destruction. The applicant for a new certificate or instrument
under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance
of such replacement Securities and may be required to provide an indemnity in favor of the Company.

Certain
Additional Risk Factors

 

In
addition to the risk factors summarized in the Company’s SEC Filings, you should consider the following:

 

An
investment in the Securities involves a high degree of risk. You should carefully consider the risks summarized in the Company’s
SEC Filings, together with all of the other information provided to you in this Agreement, before making an investment decision.
If any of the following risks actually occur, our business, financial condition or results of operations could suffer. In that
case, the trading price of our shares of Common Stock could decline, and you may lose all or part of your investment. You should
read the section entitled “Forward-Looking Statements” included in our SEC Filings for a discussion of what types
of statements are forward-looking statements, as well as the significance of such statements.

 

The
terms of this transaction and the purchase price for the Securities were not independently valued and may not be indicative of
the future price of Common Stock.

 

Our
board of directors determined the terms and conditions of this transaction, including the purchase price of the Securities. The
purchase price of the Securities was not necessarily determined to be equal to the market price of the Common Stock on the OTCQB
or the fair value of the Company. If you purchase the Securities, you may not be able to sell any of the Securities at or above
the purchase price. The trading price of the Common Stock will be determined by the marketplace and will be influenced by many
factors outside of the Company’s control, prevailing interest rates, investor perceptions, securities analyst research reports
and general industry, geopolitical, and economic conditions. Publicly traded stocks, including stocks of pharmaceutical and nutraceutical
companies, often experience substantial market price volatility. These market fluctuations might not be related to the operating
performance of particular companies whose shares are traded. Accordingly, we cannot assure you that if you purchase the Securities
you will later be able to sell any of the Securities at or above the purchase price.

 

The
Securities are “Restricted Securities” under the Securities Act and there is no assurance they will be registered.

 

The
Securities will be restricted securities under United States federal and applicable state securities laws. The Securities will
be restricted securities unless and until the Securities are registered. Restricted securities may not be transferred, sold or
otherwise disposed of in the United States, except as permitted under United States federal and state securities laws, pursuant
to registration or an exemption therefrom. You should be prepared to hold the Securities for an indefinite period.

 

The
Securities may not be sold unless, at the time of such intended sale, there is a current registration statement covering the resale
of the securities or there exists an exemption from registration under the Securities Act, and such securities have been registered,
qualified, or deemed to be exempt under applicable securities or “blue sky” laws in the state of residence of the
seller or in the state where sales are being affected.

 

If
there is not an effective registration statement covering the resale of the Securities, you will be precluded from disposing of
such shares unless such shares may become eligible to be disposed of under the exemptions provided by Rule 144 under the Securities
Act without restriction. If the Securities are not registered for resale under the Securities Act, or exempt therefrom, and registered
or qualified under applicable securities or “blue sky” laws, or deemed exempt therefrom, the value of the Securities
will be greatly reduced.

 

Insufficient
Capital

 

There
can be no assurance or guarantee that the Company will raise sufficient capital, through this transaction or otherwise, to meet
the Company’s business objectives or fund its operations. The audited financial statements of the Company include a going
concern qualification and the Company has significant liquidity issues, including that described in the SEC Filings. There can
be no assurance that other obligations that are necessary for the Company will not be incurred or that the budgeted expenditures
will not be subject to any material increase.

NEITHER
THIS SECURITY NOR THE SHARES OF COMMON STOCK ISSUABLE UPON ITS CONVERSION HAVE BEEN REGISTERED UNDER EITHER THE SECURITIES ACT
OF 1933, AS AMENDED (THE “SECURITIES ACT”) OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD, OFFERED FOR SALE,
TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT WITH RESPECT TO SUCH SECURITIES
UNDER THE SECURITIES ACT OR ANY APPLICABLE STATE SECURITIES LAWS OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH
REGISTRATION IS NOT REQUIRED.

terms hereunder, the principal sum of $_______________ on _______________ (the “Maturity Date”), unless extended
by mutual written agreement of the parties, or such earlier date as required or permitted hereunder, and to pay interest to the
Holder on the outstanding principal amount in accordance with the provisions hereof. Notwithstanding the foregoing, repayment
of this Note may be amortized upon the Maturity Date in accordance with Section 4.2. This convertible promissory note (the
“Note”) is issued pursuant to the terms of that certain Securities Purchase Agreement (the “Purchase
Agreement”) by and between the Company and the Holder, and may be prepaid or converted into common stock of the Holder,

agrees to be bound by the applicable terms of the Purchase Agreement. Capitalized terms not otherwise defined herein shall have
the meanings set forth in the Purchase Agreement.

 

The
following terms shall apply to this Note:

 

Article
I. MANNER OF PAYMENT

 

1.1
Method of Payment. All payments hereunder shall be made in lawful money of the United States of America no later than 5:00

available funds to the Holder’s account at a bank specified by the Holder in writing to the Company from time to time.

 

1.2
Business Day Convention. Whenever any amount expressed to be due by the terms of this Note is due on any day that is not
a business day, the same shall instead be due on the next succeeding business day. As used in this Note, the term “business
day” shall mean any day except any Saturday, any Sunday, any day that is a federal legal holiday in the United States, or
any day on which banking institutions in the State of New York are authorized or required by law or other governmental action
to close.

 

Article
II. INTEREST

 

2.1
Interest Rate. Except as otherwise provided herein, the outstanding principal amount of the Note shall bear interest at
a rate (the “Interest Rate”) of _______________ (__%) per annum from the date hereof and shall continue on
the outstanding principal amount of the Note until paid or converted in full in accordance with the provisions hereof.

 

    	 	 	 

    	 

    

 

2.2
Interest Payments. The Company shall pay interest in cash to the Holder (i) monthly in arrears, on or prior to the 10th
calendar day of each month, beginning on the first such date after the Issue Date, (ii) on each Conversion Date (as to that
principal amount then being converted, less any such interest amount then being converted), (iii) on each Prepayment Date (as
to that principal amount then being paid), and (iv) on the Maturity Date (as to that principal amount then being paid, if any)
(each such date, an “Interest Payment Date”).

 

2.3
Interest Calculations. Interest shall be calculated on the basis of a year of 365/366 days, as the case may be, and the
actual number of days elapsed. Interest shall accrue on the Issue Date but shall not accrue on any Conversion Date (as to that
principal amount then being converted), on any Prepayment Date (as to that principal amount then being paid), on the Maturity
Date (as to that principal amount then being paid, if any), or on up to the first 10 calendar days of each month wherein an Amortization
Payment is being made pursuant to Section 4.2 (as to that principal amount then being paid).

 

2.4
Default Interest. Upon an Event of Default (as defined in Section 6.1), the Interest Rate shall increase to eighteen
percent (18%) per annum from the date thereof until cured or waived.

 

2.5
Interest Rate Limitation. If at any time and for any reason whatsoever, the interest rate payable on the Note shall exceed
the maximum rate of interest permitted to be charged by the Holder to the Company under applicable law, such interest rate shall
be reduced automatically to the maximum rate of interest permitted to be charged under applicable law. That portion of each sum
paid attributable to that portion of such interest rate that exceeds the maximum rate of interest permitted by applicable law
shall be deemed a voluntary prepayment of principal.

 

Article
III. CONVERSION

 

3.1
Method of Conversion. At any time while this Note is outstanding, this Note shall be convertible, in whole or in part,
into shares (the “Conversion Shares”) of Common Stock at the Conversion Price (as defined below), at the option
of the Holder, at any time and from time to time. The Holder shall effect conversions by delivering to the Company a Notice of
Conversion, the form of which is attached hereto as Exhibit I (each, a “Notice of Conversion”),
specifying therein the outstanding principal amount of this Note, plus at the Holder’s option, any accrued and unpaid interest
thereon, to be converted and the date on which such conversion shall be effected (such date, a “Conversion Date”).
If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion
is deemed delivered hereunder.

 

3.2
Conversion Price. The conversion price (the “Conversion Price”) per share of Common Stock in effect
on any Conversion Date shall be equal to $____, subject to adjustment as provided below.

 

(a)
Adjustment Upon Stock Split. If at any time while this Note is outstanding, the Company: (i) subdivides outstanding shares
of Common Stock into a larger number of shares, (ii) combines (including by way of a reverse stock split) outstanding shares of
Common Stock into a smaller number of shares, or (iii) issues, in the event of a reclassification of shares of the Common Stock,
any shares of capital stock of the Company, then the Conversion Price shall be equitably adjusted. Any adjustment made pursuant
to this Section 3.2(a) shall become effective immediately after the effective date of the subdivision, combination, or
re-classification.

 

3.3
Mechanics of Conversion.

 

(a)
Conversion Shares Issuable Upon Conversion. The number of Conversion Shares issuable upon a conversion hereunder shall
be determined by the quotient obtained by dividing (x) the outstanding principal amount of this Note to be converted, plus at
the Holder’s option, any accrued and unpaid interest thereon to be converted, by (y) the Conversion Price.

 

    	 	2	 

    	 

    

 

(b)
No Fractional Shares Upon Conversion. No fractional shares shall be issued upon the conversion of this Note. As to any
fraction of a share that the Holder would otherwise be entitled to upon such conversion, the Company shall at its election, either
pay a cash adjustment in an amount equal to such fraction multiplied by the Conversion Price or round up to the next whole share.

 

(c)
Delivery of Certificate Upon Conversion. On the Conversion Date, or promptly thereafter, the Company shall issue and deliver
or cause to be issued and delivered a certificate or certificates representing the Conversion Shares.

 

(d)
Surrender of Note Upon Conversion. To effect conversions hereunder, the Holder shall not be required to physically surrender
this Note to the Company unless the entire outstanding principal amount of this Note, plus all accrued and unpaid interest thereon,
is to be converted. Conversions hereunder shall have the effect of lowering the outstanding principal amount of this Note and
accrued and unpaid interest thereon, in an amount equal to the applicable conversion, and all rights with respect to the portion
of this Note being so converted shall forthwith terminate except the right to receive the Conversion Shares, as provided herein.
The Holder and the Company shall maintain records showing the principal and interest amount(s) converted and the date of such
conversion(s). In the event of any dispute or discrepancy, the records of the Company shall be controlling and determinative in
the absence of manifest error. The Holder, and any assignee by acceptance of this Note, acknowledge and agree that, by reason
of the provisions of this paragraph, following conversion of a portion of this Note, the unpaid and unconverted principal amount
of this Note may be less than the amount stated on the face hereof.

 

(e)
Authorized Shares. The Company shall reserve from its authorized and unissued Common Stock a sufficient number of shares,
free from preemptive rights, to provide for the issuance of Common Stock upon the full conversion of this Note. The Company represents
that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable.

 

Article
IV. REPAYMENT

 

4.1
Prepayment. Notwithstanding anything to the contrary contained in this Note, the Company may prepay the amounts outstanding
hereunder pursuant to the following terms and conditions:

 

(a)
At any time while this Note is outstanding, the Company shall have the right, exercisable on not less than five (5) trading days
prior written notice (a “Prepayment Notice”) to the Holder, to prepay the Note (outstanding principal and accrued
interest), in whole or in part, without penalty.

 

(b)
Notwithstanding the Prepayment Notice, upon receipt of such notice and prior to the prepayment date (the “Prepayment
Date”) specified by the Company in the Prepayment Notice, the Holder may elect to convert any outstanding portion of
the Note, including any accrued interest, by submitting a Notice of Conversion to the Company as set forth in this Note.

 

4.2
Repayment Amortization Upon Maturity. If this Note, or any portion thereof, remains outstanding upon the Maturity Date,
then repayment of the unpaid and unconverted principal amount of this Note, shall be amortized over the following thirty-six (36)
months, with monthly payments (each, an “Amortization Payment”) to be made on or prior to the 10th
calendar day of each month, beginning on the first such date after the Maturity Date. Until this Note is repaid or converted in
full, the Holder shall continue to have all rights as a holder of this Note.

 

    	 	3	 

    	 

    

 

Article
V. CERTAIN COVENANTS

 

5.1
Sale or Disposition of Assets. So long as the Company shall have any obligation under this Note, the Company shall not,
without the Holder’s written consent, sell, lease, or otherwise dispose of all or substantially all of its assets outside
the ordinary course of business unless the proceeds of any disposition of its assets shall be used to repay this Note.

 

5.2
Non-Circumvention. The Company hereby covenants and agrees that the Company will not, by amendment of its Certificate or
Articles of Incorporation or Bylaws, or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement,
dissolution, issuance or sale of securities, or any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of this Note, and will at all times in good faith carry out all the provisions of this Note and take all action
