Exchange Act (collectively referred to herein as the “SEC
Documents”). As of their respective dates, the SEC Documents complied in
all material respects with the requirements of the Securities Act and the
Exchange Act and the rules and regulations of the Commission promulgated
thereunder applicable to such SEC Document. Except to the extent that
information contained in any SEC Document filed and publicly available prior to
the date of this Agreement has been revised or superseded by a later filed SEC
Document, which later filed SEC Document was filed prior to the date of this
Agreement, none of the SEC Documents, when filed, 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 the
circumstances under which they were made, not misleading. The financial
statements of the Company included in the SEC Documents comply as to form in all
material respects with applicable accounting requirements and the published
rules and regulations of the Commission with respect thereto as in effect at the
time of filing. Such financial statements fairly present in all material
respects the financial position of the Company as of and for the dates thereof
and the results of operations and cash flows for the periods then ended,
subject, in the case of unaudited statements, to normal, year-end audit
adjustments.

j.          Material
Changes. Since the date of the latest audited financial statements
included within the SEC Documents, except as specifically disclosed in the SEC
Documents, (i) there has been no event, occurrence or development that has had a
Material Adverse Effect, (ii) the Company has not incurred any liabilities other

business consistent with past practice, and (B) liabilities not required to be
reflected in the Company’s financial statements pursuant to GAAP or required to
be disclosed in filings made with the Commission, (iii) the Company has not

preceding the date of this Agreement, received notice from the OTCBB or any
other exchange or market on which the Common Stock is or has been listed or
quoted to the effect that the Company is not in compliance with the listing or
maintenance requirements of such exchange or market. The Company is, and has no
reason to believe that it will not in the foreseeable future continue to be, in
compliance with all such listing and maintenance requirements of the OTCBB. The
issuance and sale of the Shares hereunder does not contravene the rules and
regulations of the OTCBB and approval of the shareholders of the Company is not
required for the Company to issue and deliver to the Purchasers the number of
Shares contemplated by this Agreement.




l.          Broker’s
Fees. The Purchasers shall have no obligation with respect to any fees or
with respect to any claims made by or on behalf of other Persons for fees of any
broker, finder or other intermediary retained by the Company that may be due in
connection with the transactions contemplated by this Agreement.




2.2       Representations,
Warranties and Covenants of the Purchasers.




a.          Purchasers
Status. Purchasers represent and warrant to, and covenants with, the
Company that: (i) each Purchaser is an “accredited investor” as defined in
Regulation D under the Securities Act, and each Purchaser is also knowledgeable,
sophisticated and experienced in making, and is qualified to evaluate the risks
and merits and make decisions with respect to investments in securities
presenting an investment decision like that involved in the purchase of the
Shares, including investments in securities issued by the Company and
investments in comparable companies, and has requested, received, reviewed and
considered all information it deemed relevant in making an informed decision to
purchase the Shares and is able to bear the risks of this investment;
(ii) each Purchaser is acquiring the Shares in the ordinary course of its
business and for its own account for investment only and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act; (iii) each Purchaser will not, directly or indirectly,
offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to
buy, purchase or otherwise acquire or take a pledge of) any of the Shares except
in compliance with the Securities Act, applicable state securities laws and the
respective rules and regulations promulgated thereunder; (iv) each Purchaser
has, in connection with its decision to purchase the Shares, relied only upon
the SEC Documents and the representations and warranties of the Company
contained herein, (v) each Purchaser has answered all questions on the Investor
Questionnaire and the answers thereto are true, correct and complete in all
material respects as of the date hereof and will be true, complete and correct
in all material respects as of the Closing Date; and (vi) each Purchaser will
notify the Company immediately of any material change in any of such information
until the Closing. Purchasers understands that its acquisition of the Shares has
not been registered under the Securities Act or registered or qualified under
any state securities law in reliance on specific exemptions therefrom, which
exemptions may depend upon, among other things, the bona fide nature of the
Purchasers’ investment intent as expressed herein, and the Company is not
required and never intends to so register the Shares.


5




b.          Resale
Restrictions. Each Purchaser hereby covenants with the Company not to
make any sale of the Shares without complying with the provisions of this
Agreement and without satisfying all requirement of an applicable exemption
under the Securities Act for such sale. Each Purchaser acknowledges that the
Shares will be imprinted with the following legend that prohibits their transfer
except in accordance therewith:


THE
      SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED WITH THE SECURITIES
      AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION 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 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
  COMPANY.




c.          Short
Position. Each Purchaser hereby covenants with the Company not to use any
of the Shares acquired pursuant to this Agreement to cover any short position in
the Common Stock of the Company if doing so would be in violation of applicable
securities laws.




d.          No
Advice. Each Purchaser understands that nothing in the SEC Documents,
this Agreement or any other materials presented to the Purchasers in connection
with the purchase and sale of the Shares constitutes legal, tax or investment
advice. Each Purchaser has consulted such legal, tax and investment advisors as
it, in its sole discretion, has deemed necessary or appropriate in connection
with its purchase of the Shares.




e.          Organization;
Authority. Each Purchaser is either an individual residing in the state
as set forth on the signature page of this Agreement, or a corporation, limited
liability company or limited partnership duly formed, validly existing and in
good standing under the laws of the jurisdiction of its incorporation or
formation with the requisite power and authority to enter into and to consummate
the transactions contemplated by this Agreement and to carry out the obligations
hereunder. The purchase by Purchasers of the Shares hereunder has been duly
authorized by all necessary action on the part of the Purchasers. This Agreement
has been duly executed and delivered by each Purchaser and constitutes the valid
and legally binding obligation of each Purchaser, enforceable against each
Purchaser in accordance with its terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors’ rights generally and to
general principles of equity and except that rights to indemnification and
contribution may be limited by federal or state securities laws or public policy
relating thereto.




f.          Risk.
Each Purchaser has carefully reviewed and understands the risks of, and other
considerations relating to, the purchase of the Shares, and an investment in the
Company. Each Purchaser has adequate means of providing for its current needs
and possible future contingencies, and each Purchaser has no need, and
anticipates no need in the foreseeable future, to sell or otherwise transfer the
Shares. Each Purchaser is able to bear the economic risks of this investment
and, consequently, without limiting the generality of the foregoing, each
Purchaser is able to hold the Shares for an indefinite period of time and has
sufficient net worth to sustain a loss of its entire investment in the Company
if such loss should occur. Each Purchaser understands that the purchase of the
Shares is a highly speculative investment, which involves a high degree of risk
of loss of each Purchaser’s entire investment therein.


6




g.          Reliance.
Each Purchaser understands and acknowledges that (i) the Shares are being
offered and sold to the Purchasers without registration under the Securities Act
in a private placement that is exempt from the registration provisions of the
Securities Act under Section 4(2) of the Securities Act or Regulation D
promulgated thereunder, and (ii) the availability of such exemption depends in
part on, and the Company will rely upon the accuracy and truthfulness of, the
representations set forth in this Section 2.2, including, without limitation,
the accredited investor status and the investment intent of the Purchasers, and
each Purchaser hereby consents to such reliance.




h.          Information.
Each Purchaser and its advisors, if any, have been furnished with all materials
relating to the business, finances and operations of the Company and materials
relating to the offer and sale of the Shares which have been requested by
Purchasers or its advisors. Each Purchaser and its advisors, if any, have been
afforded the opportunity to ask questions of the Company and receive answers
concerning the terms and conditions of the offering and obtain any additional
information, which the Company possesses or can acquire without unreasonable
effort or expense, that is necessary to verify the accuracy of any
representations or information set forth in any such material. Representatives
of the Company have adequately answered all inquiries that the Purchasers have
made of them concerning the Company or any other matters relating to the
operation of the Company and sale of the Shares.




i.          Taxes.
Each Purchaser is aware that the Company and its representatives assume no
responsibility for the tax consequences to the Purchasers of any investment in
the Company.




j.          No
Representation or Promise. No one has ever represented or promised
expressly or by implication, any of the following: (i) the approximate or
exact length of time that Purchasers will be required to remain as owner of the
Shares, (ii) the amount or type of profit, or loss (including tax
write-offs and/or tax benefits) to be realized, if any, as a result of the
Purchasers’ investment, or (iii) that the past performance or experience of
the officers or directors of the Company or any affiliate, their associates,
agents, or employees or of any other person gives any assurance that the Company
will be a success.




k.          Offering
Literature; No Advertisement. No Purchaser has been furnished any
offering literature other than, and has relied only on the information contained
in, (i) the SEC Documents, and (ii) this Agreement, including the exhibits and
schedules thereto. No Purchaser is purchasing the Shares as a result of, or
subsequent to, any advertisement, article, notice or other communication
published in any newspaper, magazine or similar media or broadcast over
television or radio or presented at any seminar or meeting in which
representatives of the Company were in attendance.




l.          Governmental
Review. Each Purchaser understands that no United States federal or state
agency or any other government or governmental agency has passed upon or made
any recommendation or endorsement of the Shares.
