partnership, association or other entity. The Company is qualified to transact business as a foreign corporation and is in good
standing under the laws of each jurisdiction where the location of its properties or the conduct of its business makes such qualification

2.2        The

and delivery of each of the Transaction Documents and the issuance, sale and delivery of the Units has been duly authorized by
all necessary corporate action. The Transaction Documents have been duly executed and when delivered will constitute upon due

and other laws regarding fraudulent conveyances and preferential transfers, and except that no representation is made herein regarding
the enforceability of the Company’s obligations to provide indemnification and contribution remedies under the securities
laws and subject to the limitations imposed by general equitable principles (regardless of whether such enforceability is considered
in a proceeding at law or in equity).


 


2.3        The

than as expressly disclosed in the Offering Memorandum, no action, suit or proceeding by or before any court or governmental agency,
authority or body or any arbitrator involving the Company or its property is pending or, to the best knowledge of the Company,
threatened that (i) could reasonably be expected to have a material adverse effect on the performance of this Agreement or the
other Transaction Documents by the Company or the consummation of any of the transactions contemplated hereby or thereby, and/or
(ii) could reasonably be expected to have a material adverse effect on the Company’s operations.

Conflict. The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated hereby
will not, conflict with, or result in any violation of, or default under (with or without notice or lapse of time, or both), or

order, decree, statute, law, ordinance, rule or regulation applicable to the Company or his properties or assets. Neither the

to Securities. The Company owns beneficially and of record, and has good and indefeasible title to, the Securities, free of
all security interests, pledges, charges, liens, or encumbrances of any kind.  The Company did not acquire any of the Securities

Documents to which such Purchaser is a party and to purchase the Securities being sold to it hereunder. The execution, delivery

in accordance with the terms hereof.


 


3.3        Purchase
Entirely for Own Account. This Agreement is made with Purchaser in reliance upon Purchaser’s representation to the Company,
which by Purchaser’s execution of this Agreement, Purchaser hereby confirms that the Securities to be acquired by Purchaser

    	 	6	 



    


    

 


3.4        Purchaser
Status. At the time Purchaser was offered the Securities, it was, and as of the date hereof it is, and on each date on which
it purchases the Units and exercises the Warrants it will be either: (i) an “accredited investor” as defined in Rule
501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional buyer” as
defined in Rule 144A(a) under the Securities Act. Such Purchaser is not required to be registered as a broker-dealer under Section
15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or (iii) “non U.S. Person”
as defined under Regulation S of the Securities Act. The Purchaser has truthfully and accurately completed the Investor Questionnaire
requested in this Agreement, attached as Exhibit B (and by signing this Agreement is deemed to have signed the Investor
Questionnaire), which is hereby incorporated by reference, and will submit to the Company such further assurances of such
status as may be reasonably requested by the Company.


 


3.5        Experience
of Purchaser. 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 is able to afford a complete loss of such investment.


 


3.6        Ability
to Bear Risk. Purchaser understands and agrees that purchase of the Securities is a high risk investment and Purchaser is
able to afford and bear an investment in a speculative venture having the risks and objectives of the Company, including a risk
of total loss of such investment. Purchaser must bear the substantial economic risks of the investment in the Securities indefinitely
because none of the Securities may be sold, hypothecated or otherwise disposed of unless subsequently registered under the Securities
Act and applicable state securities laws or an exemption from such registration(s) are available.


 


3.7        Disclosure
of Information. Purchaser has been given access to full and complete information regarding the Company and has utilized such
access to Purchaser’s satisfaction for the purpose of obtaining such information regarding the Company as Purchaser has
reasonably requested. In particular, Purchaser: (i) has received and thoroughly read and evaluated the Offering Memorandum, and
any subsequent amendments or updates thereto, to which this Agreement is attached as an exhibit, as well as the Transaction Documents;
and (ii) has been given a reasonable opportunity to review such documents as Purchaser has requested and to ask questions of,
and to receive answers from, representatives of the Company concerning the terms and conditions of the Securities and the business
and affairs of the Company and to obtain any additional information concerning the Company’s business to the extent reasonably
available so as to understand more fully the nature of this investment and to verify the accuracy of the information supplied.
The Purchaser is satisfied that it has received adequate information with respect to all matters which he/she/it consider material
to its decision to make this investment.


 


3.8        No
other documents. In evaluating the suitability of an investment in the Company, the Purchaser has not relied upon any
representation or other information (oral or written) other than as stated in the Transaction Documents or as contained in documents
so furnished to the Purchaser by the Company in writing. 


 






    	 	7	 



    


    

 


3.9        Restricted
Securities. Purchaser understands that neither the Common Stock, Warrants nor the Warrants Shares have been, and will not
be, registered under the Securities Act, by reason of a specific exemption from the registration provisions of the Securities
Act, which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of Purchaser’s
representations as expressed herein. Purchaser understands that the Securities are “restricted securities” under applicable
U.S. federal and state securities laws and that, pursuant to these laws, Purchaser must hold the Securities indefinitely unless
they are registered with the Securities and Exchange Commission and qualified by state authorities, or an exemption from such
registration and qualification requirements is available. Except as otherwise provided herein or the Registration Rights Agreement,
Purchaser acknowledges that the Company has no obligation to register or qualify the Securities. Purchaser further acknowledges
that if an exemption from registration or qualification is available, it may be conditioned on various requirements including,
but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company
that are outside of Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy.


 


3.10     No
Public Market. Purchaser understands that no public market now exists for the Securities and that the Company has made no
assurances that a public market will ever exist for the Securities.

SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND HAVE BEEN ACQUIRED FOR INVESTMENT
AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH TRANSFER MAY BE EFFECTED WITHOUT AN EFFECTIVE
REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS
NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.”


 


(b)        Any
legend required by the securities laws of any state to the extent such laws are applicable to the Securities represented by the
stock certificate, instrument, or book entry so legended.


 


3.12        No
General Solicitation. The Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or
other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television
or radio or presented at any seminar or any other general solicitation or general advertisement.


 


3.13        Exculpation
Among Purchasers. Purchaser acknowledges that it is not relying upon any Person, other than the Company and its officers and
directors, in making its investment or decision to invest in the Company. Purchaser agrees that Purchaser is not liable to any
other Purchaser for any action heretofore taken or omitted to be taken by any of them in connection with the purchase of the Units.


 


3.14        Residence.

if an individual, is a citizen or resident of the United States; (iii) has adequate means of providing for Purchaser’s current
needs and personal contingencies; (iv) has no need for liquidity in Purchaser’s investments; (v) maintains Purchaser’s

net worth and current needs; and (vii) warrants that any financial information that is provided herewith by Purchaser, or is subsequently
submitted by Purchaser at the request of the Company, does or will accurately reflect Purchaser’s financial condition with
respect to which Purchaser does not anticipate any material adverse change.


 


3.16        Confidential
Information. Each Purchaser agrees that such Purchaser and its employees, agents and representatives will keep confidential
and will not disclose, divulge or use (other than for purposes of monitoring its investment in the Company) any confidential information
which such Purchaser may obtain from the Company pursuant to financial statements, reports and other materials submitted by the

to any prospective permitted transferee of the Securities, or (iii) to any general partner or affiliate of such Purchaser, so
long as the prospective transferee agrees to be bound by the provisions of this Section 3.16.


 


3.17        General.
Such Purchaser understands that the Units are being offered and sold in reliance on a transactional exemption from the registration
requirements of federal and state securities laws and the Company is relying upon the truth and accuracy of the representations,
warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein in order to determine the applicability
of such exemptions and the suitability of such Purchaser to acquire the Units.

		5.	COVENANTS



 


The
Company covenants with each of the Purchasers as follows, which covenants are for the benefit of the Purchasers and their permitted
assignees (as defined herein):


 


5.1        Securities
Compliance. The Company shall notify the Commission in accordance with its rules and regulations, of the transactions contemplated
by this Agreement and the Transaction Documents, including filing a Form D with respect to the Units, as required under Regulation
D and applicable “blue sky” laws if such Units are offered pursuant to Rule 506 of Regulation D (“Regulation

regulation, for the legal and valid issuance of the Units to the Purchasers or subsequent holders.

    	 	10	 



    


    

 


5.3        No
Integrated Offerings. The Company shall not make any offers or sales of any security (other than the securities being offered
or sold hereunder) under circumstances that would require registration of the securities being offered or sold hereunder under
the Securities Act.


 


5.4        Registration
Rights. The Purchasers are eligible for the registration rights set forth in the Registration Rights Agreement.


 


5.5        Intentionally
Left Blank.


 


5.6        Independent
Nature of Purchasers' Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several
and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance
of the obligations of any other Purchaser under any Transaction Document. The decision of each Purchaser to purchase Securities
pursuant to the Transaction Documents has been made by such Purchaser independently of any other Purchaser and independently of
any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results
of operations, condition (financial or otherwise) or prospects of the Company which may have been made or given by any other Purchaser
or by any agent or employee of any other Purchaser, and no Purchaser and none of its agents or employees shall have any liability
to any other Purchaser (or any other Person) relating to or arising from any such information, materials, statements or opinions.
Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereto or thereto,
shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the
transactions contemplated by the Transaction Documents. Each Purchaser acknowledges that no other Purchaser has acted as agent
for such Purchaser in connection with making its investment hereunder and that no Purchaser will be acting as agent of such Purchaser
in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Purchaser
shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this
Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an
additional party in any Proceeding for such purpose. It is expressly understood and agreed that each provision contained in this
Agreement is between the Company and a Purchaser, solely, and not between the Company and the Purchasers collectively and not
between and among the Purchasers.


 


5.7        Further
Assurances.  The Company shall execute any and all further documents, financing statements, agreements and instruments,
and take all further action (including filing Uniform Commercial Code, United States Patent and Trademark Office and other financing
statements not later than one (1) business day after the date hereof) that may be required under applicable law, or that the Purchasers
may reasonably request, in order to effectuate the transactions contemplated by this Agreement.


 


5.8        Best
Efforts. The Company shall exert its best efforts to satisfy the closing conditions set forth in Section 4.1 hereof or cause
such closing conditions to be satisfied at or before the Closing.

		6.	OTHER
                                         AGREEMENTS OF THE PARTIES



 


6.1        Make
Good.


 


(a)        In
the event the Company has less than $20,000,000 in gross revenue or less than $1 in earnings before interest, taxes, depreciation
and amortization (EBITDA) for the subsequent twelve months following the close of an aggregate of $6,500,000 in funding (including
the gross proceeds from this Offering) (such 12 month period, the “Make Good Period”), the Company shall issue
the Purchasers additional shares of common stock in an aggregate amount equal to twenty percent (20%) of the number of Shares
issuable pursuant to this Offering (such additional shares, the “Make Good Shares”) on a pro rata basis among
the Purchasers.


 


(b)        The
Company shall use reasonable best efforts to distribute preliminary financial statements covering the Make Good Period within
45 days after the end of the Make Good Period and audited financial statements, if requested by the Purchasers sixty days after
written notice of the request, for purposes of determining whether the Company is required to issue the Make Good Shares. If the
Company fails to use reasonable best efforts to distribute such financial statements containing the information necessary to calculate
the Company’s revenue, the number of Make Good Shares issuable shall instead be equal to one hundred percent (100%) of the
number of Shares issuable pursuant to this Offering, issued on a pro rata basis among the Purchasers. 


 


(c)        If
the Company and the Purchasers disagree as to how many Make Good Shares are due, then such dispute shall be resolved as follows:
in the case of a dispute as to the arithmetic calculation of Make Good Shares due, the Company shall submit the disputed determinations
or arithmetic calculations via facsimile within one (1) Business Day of receipt, or deemed receipt, of the event giving rise to
such dispute, as the case may be, to the Purchaser.  If the Purchaser and the Company are unable to agree upon such
determination or calculation within one (1) Business Day of such disputed determination or arithmetic calculation being submitted
to the Purchaser, then the Company shall, within one Business Day submit via facsimile the disputed arithmetic calculation of
the interest payment to the Company’s independent, outside accountant.  The Company shall cause the accountant
to perform the determinations or calculations and notify the Company and the Purchaser of the results no later than five (5) Business
Days from the time it receives the disputed determinations or calculations. Such accountant’s determination or calculation
shall be binding upon all parties absent demonstrable error.  The party whose calculation is furthest from the accountant’s
determination or calculation, shall be obligated to pay the fees and expenses of such accountant.


 






    	 	12	 



    


    

 


6.2        Per
Share Purchase Price Protection. If the Company issues Common Stock or any type of securities giving rights to receive
Common Stock at a price below the Unit Price, Purchasers will be extended full ratchet anti-dilution protection through the
issuance of additional shares of Common Stock so that the number of shares of Common
Stock issuable hereunder shall be increased such that the aggregate Purchase Price payable hereunder, after taking into
account the dilutive issuance, shall be equal to the aggregate Purchase Price prior to such dilutive issuance;
provided however, that such price protection shall not apply upon the issuance of (collectively, the “Excluded
Securities”): (i) shares of Common Stock or options or warrants to purchase Common Stock to directors, officers,
consultants or employees of the Company in their capacity as such pursuant to any stock or option plan duly adopted by the
Board of Directors of the Company, which plan does not exceed 250,000 shares in the aggregate (an “Approved Stock
Plan”), provided that the exercise price of any such options is not lowered, none of such options are amended to
increase the number of shares issuable thereunder and none of the terms or conditions of any such options are otherwise
materially changed in any manner that adversely affects the Purchasers; (ii) shares of Common Stock issued upon the
conversion or exercise of securities or rights directly or indirectly convertible into or exercisable or exchangeable, or
rights that entitle the holders of Common Stock to purchase, Common Stock (such other securities or rights are hereinafter
referred to as “Common Stock Equivalents”) (other than standard options to purchase Common Stock issued
pursuant to an Approved Stock Plan that are covered by clause (i) above) issued and outstanding on or prior to the Issue
Date, provided that the conversion or exercise (as the case may be) of any such Convertible Security is made solely pursuant
to the conversion or exercise (as the case may be) provisions of such Convertible Security that were in effect on the date
immediately prior to the Effective Date, the conversion or exercise price of any such Common Stock Equivalents (other than
standard options to purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (i) above) is
not lowered, none of such Common Stock Equivalents are (other than standard options to purchase Common Stock issued pursuant
to an Approved Stock Plan that are covered by clause (i) above) (nor is any provision of any such Common Stock
Equivalents) amended or waived in any manner (whether by the Company or the holder thereof) to increase the number of shares
issuable thereunder and none of the terms or conditions of any such Common Stock Equivalents (other than standard options to
purchase Common Stock issued pursuant to an Approved Stock Plan that are covered by clause (i) above) are otherwise
materially changed or waived (whether by the Company or the holder thereof) in any manner that adversely affects the
Purchasers; (iii) upon the issuance of the shares of Common Stock underlying the Bridge Notes and Bridge Warrants issued
pursuant to the Bridge Financing (as defined in the Offering Memorandum); (iv) upon the issuance of shares of Common Stock as
a result of any bonus, interest, make good provision or penalty issuable or payable pursuant to the terms of the Bridge Notes
or the purchase agreement pursuant to which such notes were issued; (v) upon the issuance of Warrant Shares; (vi) upon the
issuance of any Make Good Shares; (vii) upon the issuance of any warrants to the Placement Agent as compensation for the
Offering and the issuance of any shares of common stock underlying such warrants; (viii) upon the issuance of any shares of
common stock underlying the warrants issued to the Placement Agent pursuant to the Bridge Financing (as defined in the
Memorandum) and (ix) upon the Company’s issuance of securities in connection with mergers, acquisitions, strategic
license agreements and other partnering arrangements, including any such agreements in effect as of the Effective Date, so
long as such issuances are not for the purpose of raising capital and in which holders of such securities or debt are not at
any time granted registration rights. Notwithstanding the foregoing, any Common Stock issued or issuable to raise capital for
the Company or its Subsidiaries, directly or indirectly, in connection with any transaction contemplated by clause (ix)
above, including, without limitation, securities issued in one or more related transactions or that result in similar
economic consequences, shall not constitute Excluded Securities.
