2. PURCHASER REPRESENTATIONS AND WARRANTIES; ACCESS TO INFORMATION; INDEPENDENT INVESTIGATION.

The Purchaser hereby represents and warrants to the Company that:

(a) Investment Purpose. The Purchaser is acquiring the Securities for his own account for investment only and not with a view towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered or exempted under the Securities Act; provided, however, that by making the representations herein, the Purchaser reserves the right to dispose of the Securities at any time in accordance with or pursuant to an effective registration statement covering such Securities or an available exemption under the Securities Act. The Purchaser does not currently have any agreement or understanding, directly or indirectly, with any person to distribute any of the Securities.

(b) Accredited Investor Status. The Purchaser is at the date hereof, and on each date on which it exercises the Warrant, it will be either: (i) an “accredited investor” as defined

in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act. Such Purchaser is not required to be registered as a broker-dealer under Section 15 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

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

(d) Information. The Purchaser and his advisors (and his counsel), if any, have been furnished with all materials relating to the business, finances and operations of the Company and information he deemed material to making an informed investment decision regarding his purchase of the Securities which have been requested by him. The Purchaser and his advisors, if any, have been afforded the opportunity to ask questions of the Company and its management. Neither such inquiries nor any other due diligence investigations conducted by the Purchaser or his advisors, if any, or his representatives shall modify, amend or affect the Purchaser’s right to rely on the Company’s representations and warranties contained in Section 3 below. The Purchaser understands that his investment in the Securities involves a high degree of risk. The Purchaser is in a position regarding the Company, which, based upon employment, family relationship or economic bargaining power, enabled and enables the Purchaser to obtain information from the Company in order to evaluate the merits and risks of this investment. The Purchaser has sought such accounting, legal and tax advice as he has considered necessary to make an informed investment decision with respect to his acquisition of the Securities.

(e) Transfer or Resale. Purchaser understands that except as provided in the Registration Rights Agreement: (i) the Securities have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) such Purchaser shall have delivered to the Company an opinion of counsel, in a form reasonably acceptable to the Company, to the effect that such Securities to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration, or (C) such Purchaser provides the Company with reasonable assurance (in the form of seller and broker representation letters) that such Securities can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the Securities Act, as amended (or a successor rule thereto) (collectively, “Rule 144”), in each case following the applicable holding period set forth therein; notwithstanding the foregoing, the requirement to deliver a legal opinion as set out in clause (B) above shall not apply to transfers to an affiliate of the Purchaser; (ii) any sale of the Securities made in reliance on Rule 144 may be made only in accordance with the terms of Rule 144 and further, if Rule 144 is not applicable, any resale of the Securities under circumstances in which the seller (or the Person through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the Securities Act) may require compliance with some other exemption under the Securities Act or the rules and regulations of

the SEC thereunder; and (iii) neither the Company nor any other Person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. The Company reserves the right to place stop transfer instructions against the shares and certificates for the Conversion Shares and/or Warrant Shares.

(f) Legends. The Purchaser agrees to the imprinting, so long as is required by this Section 2(f), of a restrictive legend in substantially the following form:

NEITHER THE ISSUANCE NOR SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES HAVE BEEN ACQUIRED SOLELY FOR INVESTMENT PURPOSES AND NOT WITH A VIEW TOWARD RESALE AND MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL, IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT.

Certificates evidencing the Conversion Shares or the Warrant Shares shall not contain any legend (including the legend set forth above) (i) while a registration statement covering the resale of such Security is effective under the Securities Act; (ii) following any sale of such Conversion Shares or Warrant Shares pursuant to Rule 144; or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC).

(g) Authorization, Enforcement. This Agreement is a valid and binding agreement of the Purchaser enforceable in accordance with its terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

The Company has not, in the twelve (12) months preceding the date hereof, received notice from any Primary 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 Primary

4. CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

(a) Best Efforts. Each party shall use his or its best efforts to timely satisfy each of the conditions to be satisfied by it as provided in Sections 5 and 6 of this Agreement.

(b) Form D. The Company agrees to file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof to the Purchaser promptly after such filing. The Company shall, on or before the Closing Date, take such action as the Company shall reasonably determine is necessary to qualify the Securities, or obtain an exemption for the Securities for sale to the Purchaser at the Closing pursuant to this Agreement under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of any such action so taken to the Purchaser on or prior to the Closing Date.

(c) Reporting Status. Until the earlier of: (i) the date as of which the Purchaser may sell all of the Securities without restriction pursuant to Rule 144; or (ii) the date on which (A) the Purchaser shall have sold all the Securities and (B) the Note or Warrant are not outstanding, the Company shall file when due all reports required to be filed with the SEC pursuant to the Exchange Act and the regulations of the SEC thereunder, and the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the rules and regulations thereunder would otherwise permit such termination.

(d) Reservation of Shares. On the date hereof, the Company shall reserve for issuance to the Purchasers 2,000,000 shares for issuance upon conversion of the Notes and 1,200,000 shares for issuance upon exercise of the Warrants, a total of 3,200,000 shares (collectively, the “Share Reserve”). The Company represents that it has sufficient authorized and unissued shares of Common Stock available to create the Share Reserve after considering all other commitments that may require the issuance of Common Stock. The Company shall take all action reasonably necessary to at all times have authorized, and reserved for the purpose of issuance, such number of shares of Common Stock as shall be necessary to effect the full conversion of the Note and the full exercise of the Warrant. If at any time the Share Reserve is insufficient to effect the full conversion of the Note or the full exercise of the Warrant, the Company shall increase the Share Reserve accordingly. If the Company does not have sufficient authorized and unissued shares of Common Stock available to increase the Share Reserve, the Company shall call and hold a special meeting of the shareholders within thirty (30) days of such occurrence, for the sole purpose of increasing the number of shares authorized. The Company’s management shall recommend to the shareholders to vote in favor of increasing the number of shares of Common Stock authorized. Management shall also vote all of its shares in favor of increasing the number of authorized shares of Common Stock.

(h) Fees and Expenses. Except for a structuring and due diligence fee of Twenty Thousand Dollars ($20,000), to be retained from the proceeds by Purchaser, each of the Company and the Purchaser shall pay all costs and expenses incurred by such party in connection with the negotiation, investigation, preparation, execution and delivery of the Transaction Documents.

(i) Participation in Future Financing.

(i) From the date hereof until the date that is the twelve (12) month anniversary of the Closing Date, subject to participation rights in effect prior to the Closing Date between the Company and YA Global Investments, L.P. (f/k/a Cornell Capital Partners, L.P.), upon any issuance by the Company or any of its subsidiaries of Common Stock or common stock equivalents for cash consideration (a “Subsequent Financing”), the Purchaser shall have the right to participate in the Subsequent Financing, on a pro rata basis, up to an amount up to 100% of the Subsequent Financing (the “Participation Maximum”) on the same terms, conditions and price provided for in the Subsequent Financing. In connection with Purchaser’s participation in any such future financing, Purchaser shall have the right to pay for any such securities in its sole discretion by: (i) delivering the purchase price to the Company in immediately available funds by wire transfer or certified bank check, or (ii) through the cancellation of all or any portion of the outstanding balance of the Note then held by Purchaser in an amount equal to such purchase price, or through a combination of (i) and (ii) above.

(ii) At least 5 Trading Days prior to the closing of the Subsequent Financing, the Company shall deliver to the Purchaser a written notice of its intention to effect a Subsequent Financing (“Pre-Notice”), which Pre-Notice shall ask the Purchaser if he wants to review the details of such financing (such additional notice, a “Subsequent Financing Notice”). Upon the request of the Purchaser, which shall be delivered to the Company within one (1) Trading Day of the Company’s delivery of a Pre-Notice, and only upon a request by the Purchaser, for a Subsequent Financing Notice, the Company shall promptly, but no later than one (1) Trading Day after such request, deliver a Subsequent Financing Notice to the Purchaser. The Subsequent Financing Notice shall describe in reasonable detail the proposed terms of such Subsequent Financing, the amount of proceeds intended to be raised thereunder and the Person or Persons through or with whom such Subsequent Financing is proposed to be effected and shall include a term sheet or similar document relating thereto as an attachment.

(iii) The Purchaser desiring to participate in such Subsequent Financing must provide written notice to the Company by not later than 5:30 p.m. (New York City time) on the 5th Trading Day after the Purchaser has received the Pre-Notice that the Purchaser is willing to participate in the Subsequent Financing, the amount of the Purchaser’s participation, and that the Purchaser has such funds ready, willing, and available for investment on the terms set forth in the Subsequent Financing Notice. If the Company receives no notice from the Purchaser as of such 5th Trading Day, the Purchaser shall be deemed to have notified the Company that it does not elect to participate.

(iv) If by 5:30 p.m. (New York City time) on the 5th Trading Day after the Purchaser have received the Pre-Notice, notification by the Purchaser of his willingness to participate in the Subsequent Financing (or to cause their designees to participate) is, in the aggregate, less than the total amount of the Subsequent Financing, then the Company may effect the remaining portion of such Subsequent Financing on the terms and with the Persons set forth in the Subsequent Financing Notice.

(v) If by 5:30 p.m. (New York City time) on the 5th Trading Day after all of the Purchasers have received the Pre-Notice, the Company receives responses to a Subsequent Financing Notice from Purchasers seeking to purchase more than the aggregate amount of the Participation Maximum, each such Purchaser shall have the right to purchase its Pro Rata Portion (as defined below) of the Participation Maximum. “Pro Rata Portion” means the ratio of (x) the Subscription Amount of Securities purchased on the Closing Date by a Purchaser participating under this Section 4(i) and (y) the sum of the aggregate Subscription Amounts of Securities purchased on the Closing Date by all Purchasers participating under this Section 4(i).

(vi) The Company must provide the Purchasers with a second Subsequent Financing Notice, and the Purchasers will again have the right of participation set forth above in this Section 4(i), if the Subsequent Financing subject to the initial Subsequent Financing Notice is not consummated for any reason on the terms set forth in such Subsequent Financing Notice within 60 Trading Days after the date of the initial Subsequent Financing Notice.

(a) (i) The Company agrees to indemnify and hold harmless the Purchaser and his employees and agents from and against any losses, claims, damages, liabilities or expenses incurred (collectively, “Damages”), joint or several, and any action in respect thereof to which the Purchaser, his partners, affiliates, employees, and duly authorized agents, becomes subject to, resulting from, arising out of or relating to any misrepresentation, breach of warranty or non-fulfillment of or failure to perform any covenant or agreement on the part of Company contained in this Agreement, as such Damages are incurred, except to the extent such Damages result primarily from a material breach of a material representation by the Purchaser or the Purchaser’s material failure to perform any covenant or agreement contained in this Agreement (in each case, as determined by a non-appealable judgment to such effect).

(ii) The Company hereby agrees that, if the Purchaser, other than by reason of his gross negligence or willful misconduct or by reason of his trading of the Common Stock in a manner that is illegal under the federal securities laws (in each case, as determined by a non-appealable judgment to such effect), (x) becomes involved in any capacity in any action, proceeding or investigation brought by any shareholder of the Company, in connection with or as a result of the consummation of the transactions contemplated by this Agreement or the other Transaction Documents, or if the Purchaser is impleaded in any such action, proceeding or investigation by any person, or (y) becomes involved in any capacity in any action, proceeding or investigation brought by the SEC, any self-regulatory organization or other body having jurisdiction, against or involving the Company or in connection with or as a result of the consummation of the transactions contemplated by this Agreement or the other Transaction Documents, or (z)

is impleaded in any such action, proceeding or investigation by any person, then in any such case, the Company shall indemnify, defend and hold harmless the Purchaser from and against and in respect of all losses, claims, liabilities, damages or expenses resulting from, imposed upon or incurred by the Purchaser, directly or indirectly, and reimburse the Purchaser for his reasonable legal and other expenses (including the cost of any investigation and preparation) incurred in connection therewith, as such expenses are incurred. The indemnification and 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 Purchaser who are actually named in such action, proceeding or investigation, and partners, directors, agents, employees (if any), as the case may be, of the Purchaser 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 Purchaser, any such affiliate and any such person. The Company also agrees that neither the Purchaser nor any such affiliate, partner, director, agent, or employee of the Purchaser person shall have any liability to the Company or any person asserting claims on behalf of or in right of the Company in connection with or as a result of the consummation of this Agreement or the other Transaction Documents, except to the extent such liability is based on a material misrepresentation made by the Purchaser in Section 2 hereof or the Purchaser’s material failure to perform any material covenant or agreement of the Purchaser contained in the Transaction Documents (in each case, as determined by a non-appealable judgment to such effect).

(b) All claims for indemnification by any Indemnified Party (as defined below) under this Section 7 shall be asserted and resolved as follows:

(i) In the event that any claim or demand in respect of which any person claiming indemnification under any provision of this Section 7 (an “Indemnified Party”) might seek indemnity under paragraph (a) of this Section 7 is asserted against or sought to be collected from such Indemnified Party by a person other than a party hereto or an affiliate thereof (a “Third Party Claim”), the Indemnified Party shall deliver a written notification, enclosing a copy of all papers served, if any, and specifying the nature of and basis for such Third Party Claim and for the Indemnified Party’s claim for indemnification that is being asserted under any provision of this Section 7 against any person (the “Indemnifying Party”), together with the amount or, if not then reasonably ascertainable, the estimated amount, determined in good faith, of such Third Party Claim (a “Claim Notice”) with reasonable promptness to the Indemnifying Party. If the Indemnified Party fails to provide the Claim Notice with reasonable promptness after the Indemnified Party receives notice of such Third Party Claim, the Indemnifying Party shall not be obligated to indemnify the Indemnified Party with respect to such Third Party Claim to the extent that the Indemnifying Party’s ability to defend has been prejudiced by such failure of the Indemnified Party. The Indemnifying Party shall notify the Indemnified Party as soon as practicable within the period ending thirty (30) calendar days following receipt by the Indemnifying Party of either a Claim Notice or an Indemnity Notice (as defined below) (the “Dispute Period”) whether the Indemnifying Party disputes his or its liability or the amount of his or its liability to the Indemnified

Party under this Section 7 and whether the Indemnifying Party desires, at his or its sole cost and expense, to defend the Indemnified Party against such Third Party Claim. The following provisions shall also apply.

(x) If the Indemnifying Party notifies the Indemnified Party within the Dispute Period that the Indemnifying Party desires to defend the Indemnified Party with respect to the Third Party Claim pursuant to this Section 7(b), then the Indemnifying Party shall have the right to defend, with counsel reasonably satisfactory to the Indemnified Party, at the sole cost and expense of the Indemnifying Party, such Third Party Claim by all appropriate proceedings, which proceedings shall be vigorously and diligently prosecuted by the Indemnifying Party to a final conclusion or will be settled at the discretion of the Indemnifying Party (but only with the consent of the Indemnified Party in the case of any settlement that provides for any relief other than the payment of monetary damages or that provides for the payment of monetary damages as to which the Indemnified Party shall not be indemnified in full pursuant to paragraph (a) of this Section 7). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that the Indemnified Party may, at the sole cost and expense of the Indemnified Party, at any time prior to the Indemnifying Party’s delivery of the notice referred to in the first sentence of this subparagraph (x), file any motion, answer or other pleadings or take any other action that the Indemnified Party reasonably believes to be necessary or appropriate protect his or its interests; and provided further, that if requested by the Indemnifying Party, the Indemnified Party will, at the sole cost and expense of the Indemnifying Party, provide reasonable cooperation to the Indemnifying Party in contesting any Third Party Claim that the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this subparagraph (x), and except as provided in the preceding sentence, the Indemnified Party shall bear his or its own costs and expenses with respect to such participation. Notwithstanding the foregoing, the Indemnified Party may take over the control of the defense or settlement of a Third Party Claim at any time if it irrevocably waives his or its right to indemnity under paragraph (a) of this Section 7 with respect to such Third Party Claim.

(y) If the Indemnifying Party fails to notify the Indemnified Party within the Dispute Period that the Indemnifying Party desires to defend the Third Party Claim pursuant to paragraph (b) of this Section 7, or if the Indemnifying Party gives such notice but fails to prosecute vigorously and diligently or settle the Third Party Claim, each in a reasonable manner, or if the Indemnifying Party fails to give any notice whatsoever within the Dispute Period, then the Indemnified Party shall have the right to defend, at the sole cost and expense of the Indemnifying Party, the Third Party Claim by all appropriate proceedings, which proceedings shall be prosecuted by the Indemnified Party in a reasonable manner and in good faith or will be settled at the discretion of the Indemnified

Party (with the consent of the Indemnifying Party, which consent will not be unreasonably withheld). The Indemnified Party will have full control of such defense and proceedings, including any compromise or settlement thereof; provided, however, that if requested by the Indemnified Party, the Indemnifying Party will, at the sole cost and expense of the Indemnifying Party, provide reasonable cooperation to the Indemnified Party and his or its counsel in contesting any Third Party Claim which the Indemnified Party is contesting. Notwithstanding the foregoing provisions of this subparagraph (y), if the Indemnifying Party has notified the Indemnified Party within the Dispute Period that the Indemnifying Party disputes his or its liability or the amount of his or its liability hereunder to the Indemnified Party with respect to such Third Party Claim and if such dispute is resolved in favor of the Indemnifying Party in the manner provided in subparagraph(z) below, the Indemnifying Party will not be required to bear the costs and expenses of the Indemnified Party’s defense pursuant to this subparagraph (y) or of the Indemnifying Party’s participation therein at the Indemnified Party’s request, and the Indemnified Party shall reimburse the Indemnifying Party in full for all reasonable costs and expenses incurred by the Indemnifying Party in connection with such litigation. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this subparagraph (y), and the Indemnifying Party shall bear his or its own costs and expenses with respect to such participation.

(z) If the Indemnifying Party notifies the Indemnified Party that it does not dispute his or its liability or the amount of his or its liability to the Indemnified Party with respect to the Third Party Claim under paragraph (a) of this Section 7 or fails to notify the Indemnified Party within the Dispute Period whether the Indemnifying Party disputes his or its liability or the amount of his or its liability to the Indemnified Party with respect to such Third Party Claim, the amount of Damages specified in the Claim Notice shall be conclusively deemed a liability of the Indemnifying Party under paragraph (a) of this Section 7 and the Indemnifying Party shall pay the amount of such Damages to the Indemnified Party on demand. If the Indemnifying Party has timely disputed his or its liability or the amount of his or its liability with respect to such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute; provided, however, that it the dispute is not resolved within thirty (30) days after the Claim Notice, the Indemnifying Party shall be entitled to institute such legal action as it deems appropriate.

(ii) In the event that any Indemnified Party should have a claim under Section 7(a) against the Indemnifying Party that does not involve a Third Party Claim, the Indemnified Party shall deliver a written notification of a claim for indemnity under Section 7(a) specifying the nature of and basis for such claim, together with the amount or, if not then reasonably ascertainable, the estimated amount, determined in good faith, of such claim (an “Indemnity Notice”) with reasonable promptness to the Indemnifying Party. The failure by any Indemnified Party to give the Indemnity Notice shall not

impair such party’s rights hereunder except to the extent that the Indemnifying Party demonstrates that it has been irreparably prejudiced thereby. If the Indemnifying Party notifies the Indemnified Party that it does not dispute the claim or the amount of the claim described in such Indemnity Notice or fails to notify the Indemnified Party within the Dispute Period whether the Indemnifying Party disputes the claim or the amount of the claim described in such Indemnity Notice, the amount of Damages specified in the Indemnity Notice will be conclusively deemed a liability of the Indemnifying Party under Section 7(a) and the Indemnifying Party shall pay the amount of such Damages to the Indemnified Party on demand. If the Indemnifying Party has timely disputed his or its liability or the amount of his or its liability with respect to such claim, the Indemnifying Party and the Indemnified Party shall proceed in good faith to negotiate a resolution of such dispute; provided, however, that if the dispute is not resolved within thirty (30) days after the Claim Notice, the Indemnifying Party shall be entitled to institute such legal action as it deems appropriate.

(c) The indemnity agreements contained herein shall be in addition to (i) any cause of action or similar rights of the indemnified party against the indemnifying party or others, and (ii) any liabilities to which the indemnifying party may be subject.
