(w) Solvency. Based on the financial condition of the Company as of the Closing Date (and assuming the Closing shall have occurred), the Company’s assets and the Company’s ability to draw down on the Fusion Capital financing facility, the Company has sufficient capital to enable it to carry on its business for the current fiscal year as now conducted and as currently proposed to be conducted through June 30, 2007.

(x) Certain Fees. Except as may be payable to MidSouth Capital, Inc. by the Company, no brokerage or finder's fees or commissions are or will be payable by the Company to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the transactions contemplated by this Agreement.

Except as specified in the SEC Reports, the Company has not, in the two years preceding the date hereof, received notice from any Trading Market to the effect that the Company is not in compliance with the listing or maintenance requirements thereof. The issuance and sale of the Securities under the Transaction Documents does not contravene the rules and regulations of the Trading Market on which the Common Stock is currently listed or quoted, and no approval of the shareholders of the Company thereunder is required for the Company to issue and deliver to the Investors the maximum number of Securities contemplated by Transaction Documents.

(aa) Investment Company. The Company is not, and is not an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(bb) Application of Takeover Protections. The Company has taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Company's Certificate of Incorporation (or similar charter documents) or the laws of its state of incorporation that is or could become applicable to the Investors as a result of the Investors and the Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation the Company's issuance of the Securities and the Investors' ownership of the Securities.

(cc) No Additional Agreements. The Company does not have any agreement or understanding with any Investor with respect to the transactions contemplated by the Transaction Documents other than as specified in the Transaction Documents.

The Company understands and confirms that the Investors will rely on the foregoing representations and covenants in effecting transactions in securities of the Company. All written disclosures provided to the Investors regarding the Company, its business and the transactions contemplated hereby, furnished by or on behalf of the Company (including the Company’s representations and warranties set forth in this Agreement) are true and correct and do not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading.

OTHER AGREEMENTS OF THE PARTIES

(a) Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of the Securities other than pursuant to an effective registration statement, to the Company, to an Affiliate of an Investor, pursuant to Rule 144(k) or in connection with a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor, reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act.

(b) Certificates evidencing the Securities will contain the following legend, until such time as they are not required under Section 4.1(c):

[NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES HAVE BEEN REGISTERED] [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"), 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 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. [THESE SECURITIES AND THE SECURITIES ISSUABLE UPON EXERCISE OF THESE SECURITIES] [THESE SECURITIES] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT SECURED BY SUCH SECURITIES.

The Company acknowledges and agrees that an Investor may from time to time pledge, and/or grant a security interest in some or all of the Securities pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of the Securities to a financial institution that is an "accredited investor" as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement and the Registration Rights Agreement and, if required under the terms of such agreement or account, such Investor may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to approval or consent of the Company and no legal opinion of legal counsel to the pledgee, secured party or pledgor shall be required in connection with the pledge, but such legal opinion may be required in connection with a subsequent transfer following default by the Investor transferee of the pledge. No notice shall be required of such pledge. At the appropriate Investor’s expense, the Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities including the preparation and filing of any required prospectus supplement under Rule 424(b)(3) of the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders thereunder.

(c) Certificates evidencing the Shares and Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b)): (i) following a sale of such Securities pursuant to an effective registration statement (including the Registration Statement), or (ii) following a sale of such Shares or Warrant Shares pursuant to Rule 144 (assuming the transferor is not an Affiliate of the Company), or (iii) while such Shares or Warrant Shares are eligible for sale under Rule 144(k). Following such time as restrictive legends are not required to be placed on certificates representing Shares or Warrant Shares pursuant to the preceding sentence, the Company will, no later than three Trading Days following the delivery by an Investor to the Company or the Company's transfer agent of a certificate representing Shares or Warrant Shares containing a restrictive legend, deliver or cause to be delivered to such Investor a certificate representing such Shares or Warrant Shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section.

(d) Subject to the limitations set forth in Sections 1(f) and (g) of the Warrant, if the Company shall fail for any reason to cause to be issued to an Investor, within three (3) Trading Days of a reasonable written request therefor, a certificate without any restrictive legends for the number of shares of Common Stock to which the Investor is entitled pursuant to Section 4.1(c), the Company shall pay as partial liquidated damages in cash to the Investor on each day after such third Business Day that the issuance of such Common Stock is not timely effected an amount equal to 1.0% of the product of (i) the sum of the number of shares of Common Stock not issued to the Investor without any restrictive legends on a timely basis and to which the Investor is entitled and (ii) the closing price of the Common Stock as reported on the Trading Market on the Trading Day immediately preceding the third Business Day. Nothing herein shall limit such Investor’s right to pursue actual damages for the Company's failure to deliver certificates representing any Securities as required by the Transaction Documents, and such Investor shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief.

For a period of five (5) Business Days after receipt of the of the First Notice to the Investors, each Investor shall have the option, exercisable by written notice to the Company, to accept ("Notice of Acceptance") the Company’s offer as to all or any part of such Investor’s proportionate number of the New Issue Securities.

(c) The Company shall have thirty (30) Business Days after the date of the First Notice to offer, issue, sell or exchange all or any part of the New Issue Securities as to which a Notice of Acceptance has not been given by the Investors, but only upon terms and conditions that are not more favorable to the acquiring person or persons or less favorable to the Company than those set forth in the First Notice.

If any Investor becomes involved in any capacity in any Proceeding by or against any Person who is a stockholder of the Company (except as a result of sales, pledges, margin sales and similar transactions by such Investor to or with any current stockholder), solely as a result of such Investor’s acquisition of the Securities under this Agreement, the Company will reimburse such Investor for its reasonable legal and other expenses (including the reasonable cost of any investigation preparation and travel in connection therewith) incurred in connection therewith, as such expenses are incurred. The reimbursement obligations of the Company under this paragraph shall be in addition to any liability which the Company may otherwise have, shall extend upon the same terms and conditions to any Affiliates of the Investor who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees and controlling persons (if any), as the case may be, of the Investor and any such Affiliate, and shall be binding upon and inure to the benefit of any successors, assigns, heirs and personal representatives of the Company, the Investor and any such Affiliate and any such Person.

Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Investor exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then such Investor may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights.

7.13 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs associated with the issuance of such replacement Securities. If a replacement certificate or instrument evidencing any Securities is requested due to a mutilation thereof, the Company may require delivery of such mutilated certificate or instrument as a condition precedent to any issuance of a replacement.

7.14 Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Investors and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations described in the foregoing sentence and hereby agrees to waive in any action for specific performance of any such obligation the defense that a remedy at law would be adequate.

7.15 Payment Set Aside. To the extent that the Company makes a payment or payments to any Investor pursuant to any Transaction Document or an Investor enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred.

7.16 Independent Nature of Investors' Obligations and Rights. The obligations of each Investor under any Transaction Document are several and not joint with the obligations of any other Investor, and no Investor shall be responsible in any way for the performance of the obligations of any other Investor under any Transaction Document. The decision of each Investor to purchase Securities pursuant to the Transaction Documents has been made by such Investor independently of any other Investor. Nothing contained herein or in any Transaction Document, and no action taken by any Investor pursuant thereto, shall be deemed to constitute the Investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Document. Each Investor acknowledges that no other Investor has acted as agent for such Investor in connection with making its investment hereunder and that no Investor will be acting as agent of such Investor in connection with monitoring its investment in the Securities or enforcing its rights under the Transaction Documents. Each Investor 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 Investor to be joined as an additional party in any proceeding for such purpose. The Company acknowledges that each of the Investors has been provided with the same Transaction Documents for the purpose of closing a transaction with multiple Investors and not because it was required or requested to do so by any Investor.
