Such Buyer is acquiring the Securities hereunder in the ordinary course of its business. Such Buyer does not presently have any agreement or understanding, directly or indirectly, with any Person to distribute any of the Securities.

(b)           Accredited Investor Status. At the time such Buyer was offered the Securities, it was, and at the date hereof it is, and on each date on which it exercises Notes or Warrants it will be, an “accredited investor” as defined in Rule 501(a) under the 1933 Act. Such Buyer is not a registered broker-dealer under Section 15 of the 1934 Act.

(c)           Reliance on Exemptions. Such Buyer understands that the Securities 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 in part upon the truth and accuracy of, and such Buyer’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of such Buyer set forth herein in order to

3

determine the availability of such exemptions and the eligibility of such Buyer to acquire the Securities.

(d)           Information. Such Buyer 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 Securities which have been requested by such Buyer. Such Buyer and its advisors, if any, have been afforded the opportunity to ask questions of the Company. Neither such inquiries nor any other due diligence investigations conducted by such Buyer or its advisors, if any, or its representatives shall modify, amend or affect such Buyer’s right to rely on the Company’s representations and warranties contained herein. Such Buyer understands that its investment in the Securities involves a high degree of risk. Such Buyer 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 Securities.

(e)           No Governmental Review. Such Buyer 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 Securities or the fairness or suitability of the investment in the Securities nor have such authorities passed upon or endorsed the merits of the offering of the Securities.

(f)            Transfer or Resale. Such Buyer understands that except as provided in the Registration Rights Agreement: (i) the Securities have not been and are not being registered under the 1933 Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (A) subsequently registered thereunder, (B) such Buyer 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 Buyer provides the Company with reasonable assurance that such Securities can be sold, assigned or transferred pursuant to Rule 144 or Rule 144A promulgated under the 1933 Act, as amended, (or a successor rule thereto) (collectively, “Rule 144”); (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 (as defined in Section 3(s)) through whom the sale is made) may be deemed to be an underwriter (as that term is defined in the 1933 Act) may require compliance with some other exemption under the 1933 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 1933 Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder. The Securities may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the Securities and such pledge of Securities shall not be deemed to be a transfer, sale or assignment of the Securities hereunder, and no Buyer effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other Transaction Document (as defined in Section 3(b)), including, without limitation, this Section 2(f).

(g)           Legends. Such Buyer understands that the certificates or other instruments representing the Notes and the Warrants and, until such time as the resale of the

4

Conversion Shares and the Warrant Shares have been registered under the 1933 Act as contemplated by the Registration Rights Agreement, the stock certificates representing the Conversion Shares and the Warrant Shares, except as set forth below, shall bear any legend as required by the “blue sky” laws of any state and a restrictive legend in substantially the following form (and a stop-transfer order may be placed against transfer of such stock certificates):

[NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN][THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN] REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS.

(h)           Validity; Enforcement. This Agreement and the Registration Rights Agreement to which such Buyer is a party have been duly and validly authorized, executed and delivered by such Buyer and constitute the legal, valid and binding obligations of such Buyer enforceable against such Buyer in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation and other similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

(i)            No Conflicts. The execution, delivery and performance by such Buyer of this Agreement and the Registration Rights Agreement to which such Buyer is a party and the consummation by such Buyer of the transactions contemplated hereby and thereby will not (i) result in a violation of the organizational documents of such Buyer or (ii) conflict with, or

5

constitute a default (or an event which with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which such Buyer is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including federal and state securities laws) applicable to such Buyer, except in the case of clauses (ii) and (iii) above, for such conflicts, defaults, rights or violations which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Buyer to perform its obligations hereunder.

3.             REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

The Company represents and warrants to each of the Buyers that:

6

(a)           Organization and Qualification. The Company and its “Subsidiaries” (which for purposes of this Agreement means any joint venture or any entity (i) in which the Company, directly or indirectly, owns 50% or more of the outstanding capital stock or holds an equity or similar interest representing 50% or more of the outstanding equity or similar interest of such entity, (ii) that is a significant subsidiary of the Company as defined under Regulation S-X of the 1934 Act or (iii) in which the Company controls or operates all or part of the business, operations or administration of such entity) are entities duly organized and validly existing in good standing under the laws of the jurisdiction in which they are formed, and have the requisite power and authorization to own their properties and to carry on their business as now being conducted. Each of the Company and its Subsidiaries is duly qualified as a foreign entity to do business and is in good standing in every jurisdiction in which its ownership of property or the nature of the business conducted by it makes such qualification necessary, except to the extent that the failure to be so qualified or be in good standing would not reasonably be expected to have a Material Adverse Effect. As used in this Agreement, “Material Adverse Effect” means any material adverse effect on the business, properties, assets, operations, results of operations, condition (financial or otherwise) or prospects of the Company and its Subsidiaries, taken as a whole, or on the transactions contemplated hereby and the other Transaction Documents or by the agreements and instruments to be entered into in connection herewith or therewith, or on the authority or ability of the Company to perform its obligations under the Transaction Documents (as defined below). The Company has no Subsidiaries except as set forth on Schedule 3(a).

(b)           Authorization; Enforcement; Validity. The Company has the requisite power and authority to enter into and perform its obligations under this Agreement, the Notes, the Registration Rights Agreement, the Irrevocable Transfer Agent Instructions (as defined in Section 5(b)), the Warrants, the Lock-Up Agreements and each of the other agreements entered into by the parties hereto in connection with the transactions contemplated by this Agreement (collectively, the “Transaction Documents”) and to issue the Securities in accordance with the terms hereof and thereof. The execution and delivery of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby, including, without limitation, the issuance of the Notes and the Warrants, the reservation for issuance and the issuance of the Conversion Shares issuable upon conversion of the Notes and the reservation for issuance and issuance of Warrant Shares issuable upon exercise of the Warrants have been duly authorized by the Company’s Board of Directors and other than (i) the filing of a Form D under Regulation D of the 1933 Act, (ii) the filing with the SEC of one or more Registration Statements in accordance with the requirements of the Registration Rights Agreement, (iii) such filings as are required by the Principal Market (as defined below) and (iv) such filings required under applicable securities or “Blue Sky” laws of the states of the United States, no further filing, consent, or authorization is required by the Company, its Board of Directors or its stockholders. This Agreement and the other Transaction Documents of even date herewith have been duly executed and when delivered by the Company will constitute the legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except as such enforceability may be limited by general principles of equity or applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally, the enforcement of applicable creditors’ rights and remedies.

7

(c)           Issuance of Securities. The issuance of the Notes and the Warrants are duly authorized and are free from all taxes, liens and charges with respect to the issue thereof. As of the Closing, a number of shares of Common Stock shall have been duly authorized and reserved for issuance which equals 130% of the maximum number of shares Common Stock issuable upon conversion of the Notes (assuming such conversion occurred at Closing) and upon exercise of the Warrants (assuming such exercise occurred at Closing). Upon conversion in accordance with the Notes or exercise in accordance with the Warrants, as the case may be, the Conversion Shares and the Warrant Shares, respectively, when issued, will be validly issued, fully paid and nonassessable and free from all preemptive or similar rights, taxes, liens and charges with respect to the issue thereof, with the holders being entitled to all rights accorded to a holder of Common Stock. Based in part upon the accuracy of the representations and warranties of the Buyers’ set forth in Article 2, issuance by the Company of the Securities is, or will be upon issuance, exempt from registration under the 1933 Act.

(d)           No Conflicts. The execution, delivery and performance of the Transaction Documents by the Company and the consummation by the Company of the transactions contemplated hereby and thereby (including, without limitation, the issuance of the Notes and the Warrants, and reservation for issuance and issuance of the Conversion Shares and the Warrant Shares) will not (i) result in a violation of any certificate of incorporation, certificate of formation, any certificate of designations or other constituent documents of the Company or any of its Subsidiaries, any capital stock of the Company or any of its Subsidiaries or bylaws of the Company or any of its Subsidiaries or (ii) conflict with, or constitute a default (or an event which with notice or lapse of time or both would become a default) in any respect under, or give to others any rights of termination, amendment, acceleration or cancellation of, any agreement, indenture or instrument to which the Company or any of its Subsidiaries is a party, or (iii) result in a violation of any law, rule, regulation, order, judgment or decree (including foreign, federal and state securities laws and regulations and the rules and regulations of the OTC Bulletin Board as reported on Bloomberg Financial Markets LP (the “Principal Market”)) applicable to the Company or any of its Subsidiaries or by which any property or asset of the Company or any of its Subsidiaries is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect.

(e)           Consents. Other than as contemplated in Section 3(b), and otherwise as set forth on Schedule 3(e), the Company is not required to obtain any consent, authorization or order of, or make any filing or registration with, any court, governmental agency or any regulatory or self-regulatory agency or any other Person in order for it to execute, deliver or perform any of its obligations under or contemplated by the Transaction Documents, in each case in accordance with the terms hereof or thereof. All consents, authorizations, orders, filings and registrations which the Company is required to obtain pursuant to the preceding sentence have been obtained or effected on or prior to the Closing Date (other than those which the Company is not required to obtain in accordance with the Transaction Documents until after the Closing Date) and the Company and its Subsidiaries are unaware of any facts or circumstances which might prevent the Company from obtaining or effecting any of the registration, application or filings pursuant to the preceding sentence. The Company is not in violation of the listing requirements of the Principal Market and has no knowledge of any facts which would reasonably lead to delisting or suspension of the Common Stock in the foreseeable future.

8

(f)            Acknowledgment Regarding Buyer’s Purchase of Securities. The Company acknowledges and agrees that each Buyer is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby and that no Buyer is (i) an officer or director of the Company, (ii) to the Company’s knowledge, an “affiliate” of the Company (as defined in Rule 144 of the 1933 Act) or (iii) to the knowledge of the Company, a “beneficial owner” of more than 10% of the shares of Common Stock (as defined for purposes of Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “1934 Act”)). The Company further acknowledges that no Buyer is acting as a financial advisor or fiduciary of the Company or any of its Subsidiaries (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby, and any advice given by a Buyer or any of its representatives or agents in connection with the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to such Buyer’s purchase of the Securities. The Company further represents to each Buyer that the Company’s decision to enter into the Transaction Documents has been based solely on the independent evaluation by the Company and its representatives.

(g)           No General Solicitation; Placement Agent’s Fees. Neither the Company, nor any of its affiliates, nor any Person acting on its or their behalf, has engaged in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with the offer or sale of the Securities. The Company shall be responsible for the payment of any placement agent’s fees, financial advisory fees, or brokers’ commissions (other than for persons engaged by any Buyer or its investment advisor) relating to or arising out of the transactions contemplated hereby. The Company shall pay, and hold each Buyer harmless against, any liability, loss or expense (including, without limitation, attorney’s fees and out-of-pocket expenses) arising in connection with any such claim. The Company acknowledges that it has engaged Cowen and Company as placement agent (the “Placement Agent”) in connection with the sale of the Securities. Other than the Placement Agent, the Company has not engaged any placement agent or other agent in connection with the sale of the Securities.

(h)           No Integrated Offering. None of the Company, its Subsidiaries, any of their affiliates, and any Person acting on their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would require registration of any of the Securities under the 1933 Act or cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the 1933 Act or any applicable stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated. None of the Company, its Subsidiaries, their affiliates and any Person acting on their behalf will take any action or steps referred to in the preceding sentence that would require registration of any of the Securities under the 1933 Act or cause the offering of the Securities to be integrated with other offerings.

(i)            Dilutive Effect. The Company understands and acknowledges that the number of Conversion Shares issuable upon conversion of the Notes and the Warrant Shares issuable upon exercise of the Warrants will increase in certain circumstances. The Company further acknowledges that its obligation to issue Conversion Shares upon conversion of the Notes in accordance with this Agreement and the Notes and its obligation to issue the Warrant Shares upon exercise of the Warrants in accordance with this Agreement and the Warrants, in each case,

9

is absolute and unconditional regardless of the dilutive effect that such issuance may have on the ownership interests of other stockholders of the Company.

(j)            Application of Takeover Protections; Rights Agreement. The Company and its board of directors have 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 Certificate of Incorporation or the laws of the jurisdiction of its formation which is or could become applicable to any Buyer as a result of the transactions contemplated by this Agreement, including, without limitation, the Company’s issuance of the Securities and any Buyer’s ownership of the Securities. The Company has not adopted a stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership of Common Stock or a change in control of the Company.

(k)           SEC Documents; Financial Statements. Except as disclosed in Schedule 3(k), since October 7, 2005, the Company has filed all reports, schedules, forms, statements and other documents required to be filed by it with the SEC pursuant to the reporting requirements of the 1934 Act (all of the foregoing filed prior to the date hereof and all exhibits included therein and financial statements, notes and schedules thereto and documents incorporated by reference therein being hereinafter referred to as the “SEC Documents”). The Company has delivered to the Buyers or their respective representatives true, correct and complete copies of the SEC Documents not available on the EDGAR system. As of their respective dates, the SEC Documents complied in all material respects with the requirements of the 1934 Act and the rules and regulations of the SEC promulgated thereunder applicable to the SEC Documents, and none of the SEC Documents, at the time they were filed with the SEC, 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 the light of the circumstances under which they were made, not misleading. As of their respective dates, the financial statements of the Company included in the SEC Documents complied as to form in all material respects with applicable accounting requirements and the published rules and regulations of the SEC with respect thereto. Such financial statements have been prepared in accordance with generally accepted accounting principles, consistently applied, during the periods involved (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of the Company as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end audit adjustments). No other information provided by or on behalf of the Company to the Buyers which is not included in the SEC Documents, including, without limitation, information referred to in Section 2(d) of this Agreement, contains any untrue statement of a material fact or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstance under which they are or were made and not misleading.

For purposes of this Agreement:  (x) “Indebtedness” of any Person means, without duplication (A) all indebtedness for borrowed money, (B) all obligations issued, undertaken or assumed as the deferred purchase price of property or services, including (without limitation) “capital leases” in accordance with generally accepted accounting principles (other than trade payables entered into in the ordinary course of business), (C) all reimbursement or payment obligations with respect to letters of credit, surety bonds and other similar instruments, (D) all obligations evidenced by notes, bonds, debentures or similar instruments, including obligations so evidenced incurred in connection with the acquisition of property, assets or businesses, (E) all indebtedness created or arising under any conditional sale or other title retention agreement, or incurred as financing, in either case with respect to any property or assets acquired with the proceeds of such indebtedness (even though the rights and remedies of the seller or bank under such agreement in the event of default are limited to repossession or sale of such property), (F) all monetary obligations under any leasing or similar arrangement which, in

13

connection with generally accepted accounting principles, consistently applied for the periods covered thereby, is classified as a capital lease, (G) all indebtedness referred to in clauses (A) through (F) above secured by (or for which the holder of such Indebtedness has an existing right, contingent or otherwise, to be secured by) any mortgage, lien, pledge, charge, security interest or other encumbrance upon or in any property or assets (including accounts and contract rights) owned by any Person, even though the Person which owns such assets or property has not assumed or become liable for the payment of such indebtedness, and (H) all Contingent Obligations in respect of indebtedness or obligations of others of the kinds referred to in clauses (A) through (G) above; (y) “Contingent Obligation” means, as to any Person, any direct or indirect liability, contingent or otherwise, of that Person with respect to any indebtedness, lease, dividend or other obligation of another Person if the primary purpose or intent of the Person incurring such liability, or the primary effect thereof, is to provide assurance to the obligee of such liability that such liability will be paid or discharged, or that any agreements relating thereto will be complied with, or that the holders of such liability will be protected (in whole or in part) against loss with respect thereto; and (z) “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated organization and a government or any department or agency thereof.

(t)            Absence of Litigation. Except as set forth on Schedule 3(s), there is no action, suit, proceeding or investigation before or by the Principal Market, any court, public board, government agency, self-regulatory organization or body pending or, to the knowledge of the Company, threatened against or affecting the Company or any of its Subsidiaries, the Common Stock or any of the Company’s Subsidiaries or any of the Company’s or its Subsidiaries’ officers or directors, whether of a civil or criminal nature or otherwise.

(u)           Insurance. The Company and each of its Subsidiaries are insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as management of the Company believes to be prudent and customary in the businesses in which the Company and its Subsidiaries are engaged. Neither the Company nor any such Subsidiary has been refused any insurance coverage sought or applied for and neither the Company nor any such Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

(v)           Employee Relations. (i)  Neither the Company nor any of its Subsidiaries is a party to any collective bargaining agreement or employs any member of a union. The Company and its Subsidiaries believe that their relations with their employees are good. No executive officer of the Company or any of its Subsidiaries (as defined in Rule 501(f) of the 1933 Act) has notified the Company or any such Subsidiary that such officer intends to leave the Company or any such Subsidiary or otherwise terminate such officer’s employment with the Company or any such Subsidiary. No executive officer of the Company or any of its Subsidiaries is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive covenant, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability with respect to any of the foregoing matters.

14

(ii)           The Company and its Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations respecting labor, employment and employment practices and benefits, terms and conditions of employment and wages and hours, except where failure to be in compliance would not, either individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect.

(w)          Title. The Company and its Subsidiaries have good and marketable title in fee simple to all real property and good and marketable title to all personal property owned by them which is material to the business of the Company and its Subsidiaries, in each case free and clear of all liens, encumbrances and defects except such as do not materially affect the value of such property and do not interfere with the use made and proposed to be made of such property by the Company and any of its Subsidiaries. Any real property and facilities held under lease by the Company and any of its Subsidiaries are held by them under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries.

(x)            Intellectual Property Rights. The Company and its Subsidiaries own or possess adequate rights or licenses to use all trademarks, service marks and all applications and registrations therefor, trade names, patents, patent rights, copyrights, original works of authorship, inventions, licenses, approvals, governmental authorizations, trade secrets and other intellectual property rights (“Intellectual Property Rights”) necessary to conduct their respective businesses as now conducted. None of the Company’s registered, or applied for, Intellectual Property Rights have expired or terminated or have been abandoned, or are expected to expire or terminate or expected to be abandoned, within three years from the date of this Agreement. The Company does not have any knowledge of any infringement by the Company or its Subsidiaries of Intellectual Property Rights of others. There is no claim, action or proceeding being made or brought, or to the knowledge of the Company, being threatened, against the Company or any of its Subsidiaries regarding its Intellectual Property Rights. The Company is unaware of any facts or circumstances which might give rise to any of the foregoing infringements or claims, actions or proceedings.

The Company and its Subsidiaries (i) are in compliance with any and all Environmental Laws (as hereinafter defined), (ii) have received all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) are in compliance with all terms and conditions of any such permit, license or approval where, in each of the foregoing clauses (i), (ii) and (iii), the failure to so comply could be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect.

There are no unpaid taxes in any material amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company know of no basis for any such claim.

(cc)         Internal Accounting and Disclosure Controls. The Company and each of its Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities is permitted only in accordance with management’s general or specific authorization and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action is taken with respect to any difference. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-14 under the 1934 Act) that are effective in ensuring that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the SEC, including, without limitation, controls and procedures designed in to ensure that information required to be disclosed by the Company in the reports that it files or submits under the 1934 Act is accumulated and communicated to the Company’s management, including its principal executive officer or officers and its principal financial officer or officers, as appropriate, to allow timely decisions regarding required disclosure. Since October 7, 2005, neither the Company nor any of its Subsidiaries have received any notice or correspondence from any accountant identifying a material weakness in any part of the system of internal accounting controls of the Company or any of its Subsidiaries which is not specified in the Company’s Annual Report on Form 10-KSB for the fiscal year ended December 31, 2005.

For long as any Notes or Warrants remain outstanding, the Company shall not, in any manner, enter into or affect any Dilutive Issuance (as defined in the Notes) if the effect of such Dilutive Issuance is to cause the Company to be required to issue upon conversion of any Note or exercise of any Warrant any shares of Common Stock in excess of that number of shares of Common Stock which the Company may issue upon conversion of the Notes and exercise of the Warrants without breaching the Company’s obligations under the rules or regulations of the Eligible Market (as defined in the Registration Rights Agreement).

(l)            Corporate Existence. So long as any Notes remain outstanding, the Company shall not be party to any Fundamental Transaction (as defined in the Notes) unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Notes and the Warrants.

(m)          Reservation of Shares. So long as any Notes or Warrants remain outstanding, the Company shall take all action necessary to at all times have authorized, and reserved for the purpose of issuance, no less than 130% of the number of shares of Common Stock issuable upon conversion of all of the Notes and issuable upon exercise of the Warrants then outstanding (without taking into account any limitations on the conversion of the Notes or exercise of the Warrants set forth in the Notes and Warrants, respectively).

21

(n)           Conduct of Business. The business of the Company and its Subsidiaries shall not be conducted in violation of any law, ordinance or regulation of any governmental entity, except where such violations would not result, either individually or in the aggregate, in a Material Adverse Effect.

(o)           Additional Issuances of Securities.

(i)            For purposes of this Section 4(o), the following definitions shall apply.

(1)           “Convertible Securities” means any stock or securities (other than Options) convertible into or exercisable or exchangeable for shares of Common Stock.

(2)           “Options” means any rights, warrants or options to subscribe for or purchase shares of Common Stock or Convertible Securities.

(3)           “Common Stock Equivalents” means, collectively, Options and Convertible Securities.

(ii)           From the date hereof until the date that is 30 calendar days following the Effective Date (as defined in the Registration Rights Agreement) (the “Trigger Date”), the Company will not, directly or indirectly, offer, sell, grant any option to purchase, or otherwise dispose of (or announce any offer, sale, grant or any option to purchase or other disposition of) any of its or its Subsidiaries’ equity or equity equivalent securities, including without limitation any debt, preferred stock or other instrument or security that is, at any time during its life and under any circumstances, convertible into or exchangeable or exercisable for shares of Common Stock or Common Stock Equivalents (any such offer, sale, grant, disposition or announcement being referred to as a “Subsequent Placement”).

(iii)          For a period of 24 months following the Effective Date (as defined in the Registration Rights Agreement), the Company will not, directly or indirectly, effect any Subsequent Placement unless the Company shall have first complied with this Section 4(o)(iii).

(1)           The Company shall deliver to each Buyer who purchased Notes hereunder with at least a principal amount of $5 million (each, an “Eligible Buyer”) a written notice (the ”Offer Notice”) of any proposed or intended issuance or sale or exchange (the ”Offer”) of the securities being offered (the “Offered Securities”) in a Subsequent Placement, which Offer Notice shall (w) identify and describe the Offered Securities, (x) describe the price and other terms upon which they are to be issued, sold or exchanged, and the number or amount of the Offered Securities to be issued, sold or exchanged, (y) identify the persons or entities (if known) to which or with which the Offered Securities are to be offered, issued, sold or exchanged and (z) offer to issue and sell to or exchange with such Eligible Buyers at least 50% of the Offered Securities, allocated among such Eligible Buyers (a) based on such Eligible Buyer’s pro rata portion of the aggregate principal amount of Notes purchased hereunder by Eligible Buyers (the “Basic Amount”), and (b) with respect to each Eligible Buyer that elects to

22

purchase its Basic Amount, any additional portion of the Offered Securities attributable to the Basic Amounts of other Eligible Buyers as such Eligible Buyer shall indicate it will purchase or acquire should the other Eligible Buyers subscribe for less than their Basic Amounts (the “Undersubscription Amount”), which process shall be repeated until the Buyers shall have an opportunity to subscribe for any remaining Undersubscription Amount.

(2)           To accept an Offer, in whole or in part, such Eligible Buyer must deliver a written notice to the Company prior to the end of the seventh (7^th) Business Day after such Eligible Buyer’s receipt of the Offer Notice (the “Offer Period”), setting forth the portion of such Eligible Buyer’s Basic Amount that such Eligible Buyer elects to purchase and, if such Eligible Buyer shall elect to purchase all of its Basic Amount, the Undersubscription Amount, if any, that such Eligible Buyer elects to purchase (in either case, the “Notice of Acceptance”). If the Basic Amounts subscribed for by all Eligible Buyers are less than the total of all of the Basic Amounts, then each Eligible Buyer who has set forth an Undersubscription Amount in its Notice of Acceptance shall be entitled to purchase, in addition to the Basic Amounts subscribed for, the Undersubscription Amount it has subscribed for; provided, however, that if the Undersubscription Amounts subscribed for exceed the difference between the total of all the Basic Amounts and the Basic Amounts subscribed for (the “Available Undersubscription Amount”), each Eligible Buyer who has subscribed for any Undersubscription Amount shall be entitled to purchase only that portion of the Available Undersubscription Amount as the Basic Amount of such Eligible Buyer bears to the total Basic Amounts of all Eligible Buyers that have subscribed for Undersubscription Amounts, subject to rounding by the Company to the extent its deems reasonably necessary.

(3)           The Company shall have ten (10) Business Days from the expiration of the Offer Period above to (i) offer, issue, sell or exchange all or any part of such Offered Securities as to which a Notice of Acceptance has not been given by the Eligible Buyers (the “Refused Securities”), but only to the offerees described in the Offer Notice (if so described therein) and only upon terms and conditions (including, without limitation, unit prices and interest rates) that are not more favorable to the acquiring person or persons or less favorable to the Company than those set forth in the Offer Notice and (ii) to publicly announce (a) the execution of such Subsequent Placement Agreement (as defined below), and (b) either (x) the consummation of the transactions contemplated by such Subsequent Placement Agreement or (y) the termination of such Subsequent Placement Agreement, which shall be filed with the SEC on a Current Report on Form 8-K with such Subsequent Placement Agreement and any documents contemplated therein filed as exhibits thereto (the “Offer 8-K”). In the event of a breach of the foregoing covenant by the Company, any of its Subsidiaries, or any of its or their respective officers, directors, employees and agents, in addition to any other remedy provided herein or in the Transaction Documents, a Buyer shall have the right to make a public disclosure, in the form of a press release, public advertisement or otherwise, of such material, nonpublic information without the prior approval by the Company, its Subsidiaries, or any of its or their respective officers, directors, employees or agents. No Buyer shall have any liability to the Company, its Subsidiaries, or any of

23

its or their respective officers, directors, employees, stockholders or agents for any such disclosure.

(4)           In the event the Company shall propose to sell less than all the Refused Securities (any such sale to be in the manner and on the terms specified in Section 4(o)(iii)(3) above), then each Eligible Buyer may, at its sole option and in its sole discretion, reduce the number or amount of the Offered Securities specified in its Notice of Acceptance to an amount that shall be not less than the number or amount of the Offered Securities that such Eligible Buyer elected to purchase pursuant to Section 4(o)(iii)(2) above multiplied by a fraction, (i) the numerator of which shall be the number or amount of Offered Securities the Company actually proposes to issue, sell or exchange (including Offered Securities to be issued or sold to Eligible Buyers pursuant to Section 4(o)(iii)(3) above prior to such reduction) and (ii) the denominator of which shall be the original amount of the Offered Securities. In the event that any Eligible Buyer so elects to reduce the number or amount of Offered Securities specified in its Notice of Acceptance, the Company may not issue, sell or exchange more than the reduced number or amount of the Offered Securities unless and until such securities have again been offered to the Eligible Buyers in accordance with Section 4(o)(iii)(1) above.

(5)           Upon the closing of the issuance, sale or exchange of all or less than all of the Refused Securities, the Eligible Buyers shall acquire from the Company, and the Company shall issue to the Eligible Buyers, the number or amount of Offered Securities specified in the Notices of Acceptance, as reduced pursuant to Section 4(o)(iii)(3) above if the Eligible Buyers have so elected, upon the terms and conditions specified in the Offer. The purchase by the Eligible Buyers of any Offered Securities is subject in all cases to the preparation, execution and delivery by the Company and the Eligible Buyers of a purchase agreement relating to such Offered Securities reasonably satisfactory in form and substance to the Eligible Buyers and their respective counsel.

(6)           Any Offered Securities not acquired by the Eligible Buyers or other persons in accordance with Section 4(o)(iii)(3) above may not be issued, sold or exchanged until they are again offered to the Eligible Buyers under the procedures specified in this Agreement.

(iv)          The restrictions contained in subsections (ii) and (iii) of this Section 4(o) shall not apply in connection with the issuance of any Excluded Securities (as defined in the Notes).

(v)           In exchange for the Company’s willingness to agree to these procedures, each Eligible Buyer hereby irrevocably agrees that it will hold in strict confidence any and all Offer Notices, the information contained therein, and the fact that the Company is contemplating a Subsequent Placement, from the date such Eligible Buyer receives such Offer Notice until the earlier to occur of (1) the date the Offer 8-K is filed with the SEC and (2) the date such information is disclosed to the public by any Eligible Buyer in accordance with Section 4(o)(iii)(3) above. Notwithstanding anything in this Section 4(o) to the contrary, at any time any Eligible Buyer may elect, by delivering written notice to the Company, not to receive any Offer Notices hereunder and, until such time as such Eligible

24

Buyer or its successor elects, by delivering written notice to the Company, to receive Offer Notices hereunder, the Company shall not be obligated to deliver any Offer Notices to such Eligible Buyer.

(p)           Additional Registration Statements. Until the Effective Date (as defined in the Registration Rights Agreement), the Company will not file a registration statement under the 1933 Act relating to securities that are not the Securities.

(q)           Letter of Credit. On any Disclosure Date (as defined in the Notes), including, without limitation, any Disclosure Date following any LC Test Satisfaction Date (as defined below), the Company shall obtain (or maintain, as applicable) an irrevocable letter of credit (the “Letter of Credit”), in the amount of 30% of the principal amount of the outstanding Notes as of such Disclosure Date (the “Required Letter of Credit Amount”) issued in favor of Castlerigg (the “LC Agent”) by a bank acceptable to such LC Agent (the “Letter of Credit Bank”) and in form and substance acceptable to such LC Agent; provided, however, that if on any Disclosure Date the amount available to be drawn on a Letter of Credit then outstanding (together with any amounts previously drawn on such Letter of Credit by the LC Agent) is less than the Required Letter of Credit Amount, the Company shall amend or replace such Letter of Credit with a Letter of Credit (together with any amounts previously drawn on such Letter of Credit by the LC Agent) in the Required Letter of Credit Amount and in form and substance acceptable to such LC Agent. If the Net Cash Balance Test (as defined in the Note) for the Fiscal Quarter (as defined in the Note) immediately following such Disclosure Date is met, the Company shall no longer be required to maintain such Letter of Credit (such date, the “LC Test Satisfaction Date”); provided, however, that the foregoing shall not effect the Company’s obligation to obtain (or maintain, as applicable) a Letter of Credit with respect to any Disclosure Date that occurs after such LC Test Satisfaction Date. Subject to the last three sentences of this Section 4(q), the Letter of Credit shall expire not earlier than the earlier to occur of (i) the applicable LC Test Satisfaction Date and (ii) 91 days after the Maturity Date of the Notes (the “LC Expiration Date”). Upon the occurrence and during the continuance of an Event of Default under (and as defined in) the Notes, the LC Agent shall be entitled to draw under the Letter of Credit for the full Letter of Credit Amount (as defined in the Notes) then available thereunder, it being understood that the LC Agent shall act for the benefit of the Buyers on a pro rata basis based on the principal amount of the Notes held by each of the Buyers and hold such amount as collateral security for the obligations under the Notes for the benefit of the Buyers. The Company shall obtain such renewals, extensions or replacements of the Letter of Credit as necessary to ensure that the Letter of Credit shall not expire prior to the LC Expiration Date (unless the Letter of Credit shall have been reduced to zero in accordance with the terms contained in this Section 4(q) prior to such date). If, at any time, the Company cannot obtain a renewal, extension or replacement of the Letter of Credit such that the Letter of Credit will expire prior to the LC Expiration Date (a “Withdrawal Event”), the Company and the Letter of Credit Bank shall each give the LC Agent written notice of the occurrence of a Withdrawal Event at least forty-five (45) days prior to the then current expiration date of the Letter of Credit. Following a Withdrawal Event, the LC Agent shall be entitled to draw down the Letter of Credit Amount in its entirety (whether or not an Event of Default shall have occurred or be continuing under any of the Notes) and hold such amount as collateral security for the obligations under the Notes for the benefit of the Buyers.

25

(r)            LC Agent. Castlerigg is hereby appointed as the LC Agent for the Buyers hereunder, and each Buyer hereby authorizes the LC Agent (and its officers, directors, employees and agents) to take any and all such actions on behalf of such Buyer with respect to the Letter of Credit in accordance with the terms of this Agreement. The LC Agent shall not have, by reason hereof or any of the other Transaction Documents, a fiduciary relationship in respect of the Buyers. Neither the LC Agent nor any of its officers, directors, employees and agents shall have any liability to the Buyers for any action taken or omitted to be taken in connection hereof except to the extent caused by its own gross negligence or willful misconduct, and the Buyers agree to defend, protect, indemnify and hold harmless the LC Agent and all of its officers, directors, employees and agents (collectively, the “Indemnitees”) from and against any losses, damages, liabilities, obligations, penalties, actions, judgments, suits, fees, costs and expenses (including, without limitation, reasonable attorneys’ fees, costs and expenses) incurred by such Indemnitee, as incurred, whether direct, indirect or consequential, arising from or in connection with the performance by such Indemnitee of the duties and obligations of the LC Agent pursuant hereto.

(s)           Stockholder Approval. If at any time the Exchange Cap (as defined in the Notes) would limit the aggregate number of shares of Common Stock which the Company may issue upon conversion or exercise, as applicable, of the Notes and Warrants, at the written request of holders of a majority of the Conversion Shares and Warrant Shares outstanding at such time (as determined assuming full conversion of the Notes and full exercise of the Warrants prior to such date without taking into account any limitations on the conversion of the Notes or exercise of the Warrants set forth in the Notes and Warrants, respectively) (the date of such request, the “Stockholder Meeting Request Date”), the Company shall provide each stockholder entitled to vote at a special or annual meeting of stockholders of the Company (the “Stockholder Meeting”), which shall be promptly called and held not later than ninety (90) calendar days after the Stockholder Meeting Request Date (the “Stockholder Meeting Deadline”), a proxy statement, substantially in the form which has been previously reviewed by the Buyers and Schulte Roth & Zabel LLP, soliciting each such stockholder’s affirmative vote at the Stockholder Meeting for approval of resolutions providing for the Company’s issuance of all of the Securities as described in the Transaction Documents in accordance with applicable law and the rules and regulations of the Principal Market and such affirmative approval being referred to herein as the “Stockholder Approval”), and the Company shall use its reasonable best efforts to solicit its stockholders’ approval of such resolutions and to cause the Board of Directors of the Company to recommend to the stockholders that they approve such resolutions. The Company shall be obligated to use its reasonable best efforts to obtain the Stockholder Approval by the Stockholder Meeting Deadline. If, despite the Company’s reasonable best efforts the Stockholder Approval is not obtained on or prior to the Stockholder Meeting Deadline, the Company shall cause an additional Stockholder Meeting to be held every six (6) months thereafter until such Stockholder Approval is obtained or the Notes are no longer outstanding.

(t)            Lock-Up Agreements. The Company shall not amend, waive or modify the Lock-Up Agreements without the written consent of the Required Holders.

(u)           Amendment to Certificate of Incorporation. On July 31, 2006, the Company shall file an amendment to its Certificate of Incorporation to increase the number of

26

authorized shares of Common Stock from 250,000,000 to at least 400,000,000 (the “Share Increase”). The failure of the Company to effect the Share Increase no later than July 31, 2006 shall be deemed an immediate Event of Default (as defined in the Notes) pursuant to the terms of the Notes without regard to any cure periods thereunder.

5.             REGISTER; TRANSFER AGENT INSTRUCTIONS.

(a)           Register. The Company shall maintain at its principal executive offices (or such other office or agency of the Company as it may designate by notice to each holder of Securities), a register for the Notes and the Warrants in which the Company shall record the name and address of the Person in whose name the Notes and the Warrants have been issued (including the name and address of each transferee), the principal amount of Notes held by such Person, the number of Conversion Shares issuable upon conversion of the Notes and the number of Warrant Shares issuable upon exercise of the Warrants held by such Person. The Company shall keep the register open and available at all times during business hours for inspection of any Buyer or its legal representatives upon reasonable notice.

(b)           Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer agent, to issue certificates or credit shares to the applicable balance accounts at The Depository Trust Company (“DTC”), registered in the name of each Buyer or its respective nominee(s), for the Conversion Shares and the Warrant Shares issued at the Closing or upon conversion of the Notes or exercise of the Warrants in such amounts as specified from time to time by each Buyer to the Company upon conversion of the Notes or exercise of the Warrants in the form of Exhibit D attached hereto (the “Irrevocable Transfer Agent Instructions”). The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5(b), and stop transfer instructions to give effect to Section 2(g) hereof, will be given by the Company to its transfer agent, and that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement and the other Transaction Documents. Upon a Registration Event or if a Buyer effects a sale, assignment or transfer of the Securities in accordance with Section 2(f), the Company shall promptly instruct its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by such Buyer to effect such sale, transfer or assignment and, with respect to any transfer, shall permit the transfer. In the event that a Registration Event has occurred or such sale, assignment or transfer involves Conversion Shares or Warrant Shares sold, assigned or transferred pursuant to an effective registration statement or pursuant to Rule 144, the transfer agent shall issue such Securities to the Buyer, assignee or transferee, as the case may be, without any restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to a Buyer. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this Section 5(b) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5(b), that a Buyer shall be entitled, in addition to all other available remedies, to an order and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required.

(a)           Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or

30

proceeding is improper.

(g)           Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns, including any purchasers of the Notes or the Warrants. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Required Holders (unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Notes and the Warrants). A Buyer may assign some or all of its rights hereunder without the consent of the Company, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights.

(h)           No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person.

(i)            Survival. Unless this Agreement is terminated under Section 8, the representations and warranties of the Company and the Buyers contained in Sections 2 and 3 and the agreements and covenants set forth in Sections 4, 5 and 9 shall survive the Closing and the delivery and exercise of Securities, as applicable. Each Buyer shall be responsible only for its own representations, warranties, agreements and covenants hereunder.

(j)            Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the transactions contemplated hereby.

(k)           Indemnification. In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless each Buyer and each other holder of the Securities and all of their stockholders, partners, members, officers, directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement) (collectively, the “Indemnitees”) from and against any and all actions, causes of action, suits, claims, losses, costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is sought), and including reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or breach of any representation or warranty made by the

33

Company in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company contained in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these purposes a derivative action brought on behalf of the Company) and arising out of or resulting from (i) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (ii) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, (iii) any disclosure made by such Buyer pursuant to Section 4(i) or (iv) the status of such Buyer or holder of the Securities as an investor in the Company pursuant to the transactions contemplated by the Transaction Documents. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and obligations under this Section 9(k) shall be the same as those set forth in Section 6 of the Registration Rights Agreement.

(l)            No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(m)          Remedies. Each Buyer and each holder of the Securities shall have all rights and remedies set forth in the Transaction Documents and all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law. Any Person having any rights under any provision of this Agreement shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore, the Company recognizes that in the event that it fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law may prove to be inadequate relief to the Buyers. The Company therefore agrees that the Buyers shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security.

(n)           Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) the Transaction Documents, whenever any Buyer 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 Buyer 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.

(o)           Payment Set Aside. To the extent that the Company makes a payment or payments to the Buyers hereunder or pursuant to any of the other Transaction Documents or the Buyers enforce or exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated,

34

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, foreign, 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.

(p)           Independent Nature of Buyers’ Obligations and Rights. The obligations of each Buyer under any Transaction Document are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations of any other Buyer under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Buyers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents and the Company acknowledges that the Buyers are not acting in concert or as a group, and the Company will not assert any such claim, with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Buyer confirms that it has independently participated in the negotiation of the transaction contemplated hereby with the advice of its own counsel and advisors. Each Buyer shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose.
