          (a) Organization and Standing. The Company is duly incorporated and validly existing
under the laws of the State of Delaware and has all requisite corporate power and authority to own
or lease its properties and assets and to conduct its business as it is presently



 









 




being conducted.




          (b) Capitalization. Immediately subsequent to the consummation of the transactions

          (c) Capacity of the Company; Consents; Execution of Agreements. The Company has all
requisite power, authority and capacity to enter into this Agreement and to perform the
transactions and obligations to be performed by it hereunder. The execution and delivery of this
Agreement and any agreements contemplated hereby by the Company, and the performance by the Company
of the transactions and obligations contemplated hereby and thereby, including, without limitation,
the issuance and delivery of the Securities to the Investor, has been duly authorized by all
requisite action of the Company and Stockholders. This Agreement has been duly executed and
delivered by a duly authorized officer of the Company and constitutes a valid and legally binding
agreement of the Company, enforceable in accordance with its respective terms, except as
enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other
similar laws of the United States (both state and federal), affecting the enforcement of creditors’
rights or remedies in general and general equity principles.



          (d) Status of the Shares and Warrant Shares; Reservation of Common Stock. The Shares
and Warrant Shares to be issued and purchased hereunder, when issued by the Company to the Investor
and paid for by the Investor pursuant to the terms of this Agreement and the Warrant, will (i) be
duly authorized, validly issued, fully paid and nonassessable, (ii) based on the Investor’s
representations in Section 4.2, have been issued in compliance with all applicable United States
federal and state securities laws and (iii) be free and clear of all Liens. The Company has
available sufficient shares of Common Stock for issuance pursuant to the terms of this Agreement.



          (e) Conflicts; Defaults. The execution and delivery of this Agreement by the Company
and the performance by the Company of the transactions and obligations contemplated hereby to be
performed by it will not (i) materially violate, conflict with, or constitute a default under any
of the terms or provisions of, the Certificate of Incorporation, the bylaws, or any provisions of,
or result in the acceleration of any obligation under, any material contract, note, debt
instrument, security agreement, or other instrument to which the Company is a party or by
which the Company, or any of their assets is bound (collectively, the “Material Agreements”);
(ii) result in the creation or imposition of any Liens or claims upon the Company’s assets or upon
the Company’s Common Stock; (iii) assuming the accuracy of the Investor’s representations in
Section 4.2, constitute a material violation of any law, statute, judgment, decree, order, rule, or
regulation of a Governmental Authority applicable to the Company; or (iv) constitute an event
which, after notice or lapse of time or both, would result in any of the foregoing. The Company is
not presently in violation of its Certificate of Incorporation or bylaws.



 









 





          (f) Compliance with Laws. The Company is not in violation of, nor do any of its
respective operations violate in any respect, any statute, law, or regulation of any Governmental
Authority applicable to the Company (“Applicable Laws”), which violation would have a Material
Adverse Effect.



          (g) Litigation. As of the date hereof: (i) the Company is not subject to any order of,
or written agreement or memorandum of understanding with, any Governmental Authority which would
have a Material Adverse Effect; (ii) there are no material actions, suits, claims, investigations,
or proceedings pending at law or in equity or before or by any Governmental Authority, or, to the
Knowledge of the Company, threatened, against the Company or any of its assets or properties or the
transactions contemplated by this Agreement, and to the Knowledge of the Company, there exist no
facts or circumstances which reasonably could be anticipated to result in any such action, suit,
claim, investigation, or proceeding; and (iii) no Person has asserted, and, to the Knowledge of the
Company, no Person has a valid basis upon which to assert, any claims against the Company that
would materially adversely affect the transactions contemplated by this Agreement or result in or
form the basis of any such action, suit, claim, investigation or proceeding. There is no material
action, suit, proceeding or investigation by the Company currently pending or which the Company
intends to initiate.



          (h) Securities Laws.



               (i) The Company has filed all forms, reports and documents with the SEC required to be filed
by it pursuant to the federal securities laws and the SEC rules and regulations thereunder, all of
which complied in all material respects with all applicable requirements of the Securities Act and
the Exchange Act (collectively, the “SEC Reports”). None of the SEC Reports, including, without
limitation, any financial statements or schedules included therein, at the time filed (or if
amended or superseded by a filing prior to the date of this Agreement, then on the date of such
filing) contained any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements therein, in light of
circumstances under which they were made, not misleading.



               (ii) Based on the Investor’s representations in Section 4.2, no consent, authorization,
approval, permit, or order of or filing with any Governmental Authority is required in order for
the Company to execute and deliver this Agreement or in order for the Company to offer, issue,
sell, or deliver the Securities. Based in part on the representations of the Investor and under
the circumstances contemplated hereby and under current laws and regulations, the offer, issuance,
sale and delivery of the Securities to the Investor is exempt from the registration
requirements of the Securities Act.



          (i) Taxes. The Company has timely filed or caused to be filed with the appropriate
taxing authority all federal, state, national, local and foreign returns, estimates, information
statements and reports (“Returns”) relating to Taxes required to be filed by the Company on or
prior to the Closing Date. The Returns have accurately reflected in all material respects and will
accurately reflect in all material respects all liability for Taxes of the Company for the periods
covered thereby.





 









 





     4.2 Representations and Warranties of the Investor




     The Investor hereby represents and warrants to the Company that as of the date hereof:



          (a) Investment Intent. The Securities to be purchased by the Investor hereunder are
being purchased for its own account and not with the view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Securities Act. The Investor
understands that the Securities have not been registered under the Securities Act by reason of
their issuance in transactions exempt from the registration and prospectus delivery requirements of
the Securities Act pursuant to Section 4(2) thereof. The Investor further understands that the
certificates representing the Shares and any Warrant Shares that may be issued pursuant to the
exercise of the Warrant will bear the following legend and the Investor agrees that it will hold
such shares subject thereto:




“THESE SECURITIES HAVE 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”), OR ANY APPLICABLE STATE SECURITIES LAWS 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 COMPLIANCE WITH APPLICABLE STATE
SECURITIES LAWS OR BLUE SKY LAWS.”



          (b) Capacity of the Investor; Execution of Agreement. The Investor has all requisite
power, authority and capacity to enter into this Agreement, deliver the Purchase Price, and to
perform the transactions and obligations to be performed by it hereunder. This Agreement has been
duly authorized, executed and delivered by them and constitutes its valid and legally binding
obligation, enforceable in accordance with its terms, except as enforcement thereof may be limited
by bankruptcy, insolvency, reorganization, moratorium or other similar laws, both state and
federal, affecting the enforcement of creditors’ rights or remedies in general from time to time in
effect and the exercise by courts of equity powers or their application of principles of
public policy.



          (c) Accredited Investor. The Investor is an “accredited investor” as defined in Rule
501(a) of Regulation D promulgated under the Securities Act (“Regulation D”).



          (d) Suitability and Sophistication. (i) The Investor has such knowledge and experience
in financial and business matters that it is capable of independently evaluating the risks and
merits of purchasing the Securities; (ii) the Investor has independently evaluated the risks and
merits of purchasing the Securities and has independently determined that the Securities are a
suitable investment for it; and (iii) the Investor has sufficient financial resources to bear the
loss of their entire investment in the Securities.



          (e) Receipt of Information. The Investor believes, after due inquiry and




 











 




investigation, that it has received all of the information that it considers necessary or
appropriate for deciding whether to purchase the Securities. The 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 Securities and the business, properties, prospects and
financial condition of the Company and to obtain additional information (to the extent the Company
possessed such information or could acquire it without unreasonable effort or expense) necessary to
verify the accuracy of any information furnished to the Investor. The foregoing, however, does not
limit or modify the representations and warranties of the Company in Section 4 of this Agreement or
the right of the Investor to rely thereon.




          (f) Independent Existence. The Investor was not formed for the specific purpose of
purchasing the Securities.
