      against the Company in accordance with their terms, except as such
      enforceability may be limited by applicable bankruptcy, reorganization,
      moratorium, liquidation, conservatorship, receivership or similar laws relating
      to, or affecting generally the enforcement of, creditor's rights and remedies
      or
      by other equitable principles of general application.




Section
      2.2  Representations
      and Warranties of the Purchasers .




Each
      of
      the Purchasers represents and warrants to the Company with respect solely to
      itself and not with respect to any other Purchaser as of the date hereof and
      as
      of each Closing Date on which it purchases Notes, that:




(a)  Organization
      and Standing of the Purchasers .
      If the
      Purchaser is an entity, such Purchaser is a corporation, limited liability
      company or partnership duly incorporated or organized, validly existing and
      in
      good standing under the laws of the jurisdiction of its incorporation or
      organization and has not been organized for the specific purposes of purchasing
      the Notes and is not prohibited from doing so.




(b)  Authorization
      and Power; Enforcement .
      Such
      Purchaser has the requisite power and authority to enter into and perform its
      obligations under this Agreement and to purchase the Notes being sold to it
      hereunder. The execution, delivery and performance of this Agreement by such
      Purchaser has been duly authorized by all necessary corporate, partnership
      or
      limited liability company action. When executed and delivered by such Purchaser,
      this Agreement shall constitute valid and binding obligations of such Purchaser
      enforceable against such Purchaser in accordance with its terms, except as
      such
      enforceability may be limited by applicable bankruptcy, insolvency,
      reorganization, moratorium, liquidation, conservatorship, receivership or
      similar laws relating to, or affecting generally the enforcement of, creditor's
      rights and remedies or by other equitable principles of general
      application.


2


(c)  Investment
      Purpose .
      Such
      Purchaser is acquiring the Notes as principal for its own account for investment
      only and not with a view toward, or for resale in connection with, the public
      sale or distribution thereof.




(d)  Accredited
      Investor Status .
      Such
      Purchaser is an “Accredited Investor” as that term is defined in Rule 501(a)(3)
      of Regulation D, as further indicated by his or its responses to the Purchaser
      Questionnaire which it has submitted to the Company.




(e)  Reliance
      on Exemptions .
      Such
      Purchaser understands that the Notes are being offered and sold to it in
      reliance on specific exemptions from the registration requirements of United
      States federal and state securities laws and that the Company is relying upon
      the truth and accuracy of, and such Purchaser’s compliance with, the
      representations, warranties, agreements, acknowledgments and understandings
      of
      such Purchaser set forth herein in order to determine the availability of such
      exemptions and the eligibility of such Purchaser to acquire the
      Notes.




(f)  Information;
      Able to Bear Risk .
      Such
      Purchaser specifically acknowledges that it has read the Company’s Annual Report
      on Form 10-KSB for the year ended September 30, 2007, including without
      limitation the Risk Factors section set forth and therein, and all Current
      Reports on Form 8-K since the filing of its Annual Report on Form 10-KSB for
      the
      year ended September 30, 2007. Such Purchaser and its advisors (and/or its
      counsel, if any) have been furnished with all materials relating to the
      business, finances and operations of the Company and information which it deemed
      material to making an informed investment decision regarding its purchase of
      the
      Notes, which have been requested by such Purchaser. Such Purchaser and its
      advisors, if any, have been afforded the opportunity to ask questions of the
      Company and its management. Such Purchaser is not relying (for purposes of
      making any investment decision or otherwise) upon any advice, information,
      or
      representations from the Company, written or oral, other than the
      representations set forth in this Agreement. Such Purchaser is fully aware
      of
      the precarious financial condition of the Company and understands that such
      Purchaser’s investment in the Notes is speculative and involves an extremely
      high degree of risk, and that the Company does not currently have the financial
      resources to repay the Notes. Such Purchaser, either alone or 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 hereunder and such Purchaser is able to bear the
      economic risk of such investment, and is able to afford a complete loss of
      such
      investment. Such Purchaser is in a position regarding the Company, based upon
      employment, directorship, family relationship or economic bargaining power,
      which enabled and enables such Purchaser to obtain information from the Company
      in order to evaluate the merits and risks of this investment. Such Purchaser
      has
      sought such accounting, legal and tax advice, as it has considered necessary
      to
      make an informed investment decision with respect to its acquisition of the
      Notes. Such Purchaser is not making the investment as a result of any
      advertisement, article, notice or other communication published or broadcast
      in
      any media or any general solicitation or advertising.


3


(g)  No
      Governmental Review .
      Such
      Purchaser understands that no United States federal or state agency or any
      other
      government or governmental agency has passed on or made any recommendation
      or
      endorsement of the Notes, or the fairness or suitability of an investment in
      the
      Notes, nor have such authorities passed upon or endorsed the merits of the
      offering of the Notes.




(h)  Transfer
      or Resale .
      Such
      Purchaser understands that: (i) the Notes are non-negotiable and (without the
      consent of the Company) non-transferable; (ii) the Notes have not been and
      are
      not being registered under the Securities Act or any state securities laws,
      and
      (even if the Company were to consent to a transfer of the Notes) may not be
      offered for sale, sold, assigned or transferred by Purchaser unless (A)
      subsequently registered for resale thereunder, or (B) such Purchaser shall
      have
      delivered to the Company an opinion of counsel, in form, substance and scope
      acceptable to the Company, to the effect that the Notes to be sold, assigned
      or
      transferred may be sold, assigned or transferred pursuant to a specified
      exemption from such registration requirements; and (iii) neither the Company
      nor
      any other person is under any obligation to register the Notes under the
      Securities Act or any state securities laws or to comply with the terms and
      conditions of any exemption thereunder. Such Purchaser acknowledges that it
      is
      familiar with Rule 144 of the rules and regulations of the Commission, as
      amended, promulgated pursuant to the Securities Act (“ Rule
      144 ”),
      and
      that such Purchaser has been advised that Rule 144 permits resales only under
      certain circumstances. Such Purchaser understands that to the extent that Rule
      144 is not available, such Purchaser will be unable to sell the Notes without
      either registration under the Securities Act or the existence of another
      exemption from such registration requirement. Such Purchaser understands that
      no
      public market exists or will exist for the Notes.




(i)  Legends .
      Such
      Purchaser understands that the Notes shall bear a restrictive legend in
      substantially the following form:




THIS
      NOTE
      HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE OFFERED
      FOR SALE, SOLD, TRANSFERRED, ASSIGNED, PLEDGED OR OTHERWISE DISPOSED OF IN
      THE
      ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE NOTES UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF COUNSEL, IN FORM, SUBSTANCE
      AND SCOPE SATISFACTORY TO THE ISSUER OF THIS NOTE, THAT REGISTRATION IS NOT
      REQUIRED UNDER SAID ACT.




(j)  Receipt
      of Documents .
      Such
      Purchaser and his or its counsel has received and read in their entirety: (i)
      the Transaction Documents; (ii) all due diligence and other information which
      it
      has requested; and (iii) answers to all questions such Purchaser submitted
      to
      the Company regarding an investment in the Company; and such Purchaser [has
      not
      been furnished any other documents, literature, memorandum or prospectus and]
      has relied only on the representations set forth in the Transaction Documents
      and on the Company’s filings with the Securities and Exchange
      Commission.


4


(k)  No
      Legal Advice From either Company .
      Such
      Purchaser acknowledges that it had the opportunity to review this Agreement
      and
      the transactions contemplated by this Agreement with his or its own legal
      counsel and investment and tax advisors. Such Purchaser is relying solely on
      such counsel and advisors and not on any statements or representations of the
      Company or any of its representatives or agents for legal, tax or investment
      advice with respect to this investment, the transactions contemplated by this
      Agreement or the securities laws of any jurisdiction.




(l)  Use
      of
      Proceeds .
      Such
      Purchaser acknowledges that it knows that a substantial portion of the proceeds
      of the sale of the Notes will be used to pay past due and current accounts
      payable of the Company.
