foregoing includes, without limitation, actions pending or to the Company’s knowledge threatened (or any basis therefor known
to the Company) involving the prior employment of any of the Company’s employees, their use in connection with the Company’s

government
agency or instrumentality. There is no action, suit, proceeding or investigation by the Company currently pending or which the
Company intends to initiate.


 


2.8          Proprietary
Information Agreements.    Each present employee and officer of the Company with access to confidential
information of the Company or involved in the development of the Company’s Intellectual Property has executed a confidentiality
and inventions assignment agreement (the “Proprietary Information Agreement”),
a form of which is available for review upon request to the Company, and no exceptions have been taken by any such employee or
officer to the terms of such agreement. The Company, after reasonable investigation, is not aware that any of its employees or
consultants are in violation thereof, and the Company will use its best efforts to prevent any such violation. All present consultants
to or vendors of the Company with access to confidential information of the Company are parties to a written agreement substantially
similar to the Proprietary Information Agreement under which, among other things, each such consultant or vendor is obligated to
maintain the confidentiality of information of the Company.


 


2.9          Intellectual
Property.


 


(a)          Ownership.
The Company owns or possesses sufficient legal rights to all patents, trademarks, service marks, trade names, copyrights, trade
secrets, licenses (software or otherwise), information, processes and similar proprietary rights (“Intellectual Property”)
necessary to the business of the Company as presently conducted, the lack of which could reasonably be expected to have a Material
Adverse Effect, without any conflict with or infringement of the rights of others. Except for agreements with its own employees
or consultants, standard end-user license agreements, support/maintenance agreements and agreements entered in the ordinary course
of the Company’s business, there are no outstanding options, licenses or agreements relating to the Intellectual Property,
and the Company is not bound by or a party to any options, licenses or agreements with respect to the Intellectual Property of
any other person or entity. The Company has not received any written communication alleging that the Company has violated or, by
conducting its business as currently conducted, would violate any of the Intellectual Property of any other person or entity, nor
is the Company aware of any basis therefor. The Company is not obligated to make any payments by way of royalties, fees or otherwise
to any owner or licensor of or claimant to any Intellectual Property with respect to the use thereof in connection with the conduct
of its business as presently conducted. There are no agreements, understandings, instruments, contracts, judgments, orders or decrees
to which the Company is a party or by which it is bound which involve indemnification by the Company with respect to infringements
of Intellectual Property.


 


(b)          No
Breach by Employees. The Company is not aware that any of its employees is obligated under any contract or other agreement,
or subject to any judgment, decree or order of any court or administrative agency, that would materially interfere with the use
of his or her efforts to promote the interests of the Company or that would conflict with the Company’s business as presently
conducted. Neither the execution nor delivery of this Agreement, nor the carrying on of the Company’s business by the employees
of the Company, nor the conduct of the Company’s business as presently conducted, will, to the Company’s knowledge,
conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant
or instrument under which any of such


 




    	- 5 -



    	 



    

  


employees is now obligated.
The Company does not believe it is or will be necessary to use any inventions of any of its employees made prior to their employment
by the Company.

Company is not in violation or default of any provisions of its Restated Certificate or Bylaws or of any instrument, judgment,
order, writ, decree or contract to which it is a party or by which it is bound or, to its knowledge, of any provision of federal
or state statute, rule or regulation applicable to the Company. The execution, delivery and performance of this Agreement and the
other Financing Agreements, and the consummation of the transactions contemplated hereby and thereby will not result in any violation,
which could result in a Material Adverse Effect, or be in conflict with or constitute, with or without the passage of time and
giving of notice, either a default under any such provision, instrument, judgment, order, writ, decree or contract or an event
which results in the creation of any lien, charge or encumbrance upon any assets of the Company.


 


(b)          The
Company has avoided every condition, and has not performed any act, the occurrence of which would result in the Company’s
loss of any right granted under any license, distribution or other agreement.


 


2.11        Disclosure.
   The Company has fully provided each Investor with all the information which such Investor has requested for deciding whether to
purchase the Shares and Warrants and all information which the Company believes is reasonably necessary to enable such Investor
to make such decision. Neither this Agreement nor any other statements, exhibits or certificates made or delivered in connection
herewith contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements herein
or therein not misleading which has not been, prior to the Closing, corrected or amended.


 


2.12        Registration
Rights.    Except as provided in the Investors’ Rights Agreement, the Company has not
granted or agreed to grant any rights to register any securities of the Company with any governmental entity, including piggyback
rights, to any person or entity.


 


2.13        Title
to Property and Assets.   The Company owns its property and assets free and clear of all mortgages,
liens, loans and encumbrances, except such encumbrances and liens which arise in the ordinary course of business and do not materially
impair the Company’s ownership or use of such property or assets. With respect to the property and assets it leases, the
Company is in compliance with such leases and, to its knowledge, holds a valid leasehold interest free of any liens, claims or
encumbrances.


 


2.14        Private
Placement.   Subject in part to the truth and accuracy of the Investors’ representations
set forth in this Agreement, the offer, sale and issuance of the Shares and Warrants as contemplated by this Agreement is exempt
from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”), and neither the
Company nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemption.

3.            Representations
and Warranties of the Investors.    Each Investor hereby represents and warrants that:


 


3.1          Authorization.
   The Financing Agreements constitute its valid and legally binding obligations, enforceable in accordance with their terms.


 


3.2          Purchase
Entirely for Own Account.    This Agreement is made with such Investor in reliance upon such
Investor’s representation to the Company, which by such Investor’s execution of this Agreement such Investor hereby
confirms, that the Securities will be acquired for investment for such Investor’s own account, not as a nominee or agent,
and not with a view to the resale or distribution of any part thereof, and that such Investor has no present intention of selling,
granting any participation in, or otherwise distributing the same. By executing this Agreement, each Investor further represents
that such Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant
participation to such person or to any third person, with respect to any of the Securities. Each Investor represents that it has
full power and authority to enter into the Financing Agreements.


 


3.3          Disclosure
of Information.    The Investor believes it has received all the information it considers necessary
or appropriate for deciding whether to purchase the Shares and the Warrants. Each Investor further represents that it has had an
opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Shares
and the Warrants. The foregoing, however, does not limit or modify the representations and warranties of the Company in Section
2 of this Agreement or the right of the Investors to rely thereon.


 


3.4          Investment
Experience.    The Investor is an “accredited investor” as that term is defined
in Rule 501 of Regulation D promulgated under the Securities Act, has filled out and executed the Accredited Investor Questionnaire
attached hereto as Exhibit F-1 and the Rule 506 Disqualification Event Questionnaire
attached hereto as Exhibit F-2 and is an investor in securities of companies in
the development stage and acknowledges that it is able to protect its interests, and bear the economic risk of its investment and
has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the
investment in the Securities. If other than an individual, such Investor also represents it has not been organized for the purpose
of acquiring the Shares or Warrants or, if Investor has been formed for 


 




    	- 9 -



    	 



    

  


the
purpose of acquiring the Shares or Warrants, then each of the beneficial owners of Investor is an “accredited investor”
and individually meets the criteria described in this Section 3.4.


 


3.5          Restricted
Securities.    The Investor understands that the Shares and the Warrants it is purchasing and
the Conversion Stock and Warrant Shares are characterized as “restricted securities” under the federal securities laws
inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws
and applicable regulations such securities may be resold without registration under the Securities Act only in certain limited
circumstances. In this connection, the Investor represents that it is familiar with Rule 144 promulgated under the Securities Act,
as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.


 


3.6          No
Public Market.   The Investor understands that no public market now exists for any of the securities
issued by the Company and that the Company has made no assurances that a public market will ever exist for the Company’s
securities.


 


3.7          Economic
Risk.    The Investor understands that the Company has limited financial and operating history
and that investment in the Company involves substantial risks. The Investor understands all of the risks related to the purchase
of the Securities. The Investor further understands that the purchase of the Securities will be a highly speculative investment.
The Investor is able, without impairing the Investor’s financial condition, to hold the Securities for an indefinite period
of time and to suffer a complete loss of the Investor’s investment.


 


3.8          Brokers
or Finders.   The Company has not, and will not, incur, directly or indirectly, as a result
