EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE CONSTITUENT COMPANIES

2.01

Effect on Capital Stock and Company Notes. As of the Effective Time, by virtue of the Merger and without any action on the part of the Company, Merger Sub or any holder of any shares of Company Common Stock, Company Notes, Company Warrants, In the Money Company Warrants or any common stock of Merger Sub:

(a)	Common Stock of Merger Sub. Each share of common stock of Merger Sub outstanding immediately prior to the Effective Time shall be converted into one share of the common stock, par value $0.001 per share, of the Surviving Corporation.

(b)

Cancellation of Treasury Stock and Parent-Owned Company Stock. Each share of Company Common Stock that is owned by the Company, and each share of Company Common Stock that is owned by Parent, Merger Sub or any other Subsidiary of Parent shall automatically be cancelled and retired and shall cease to exist, and no cash, Parent Capital Stock or other consideration shall be delivered or deliverable in exchange therefor.

(c)	Conversion of Company Common Stock and In the Money Company Warrants.

(i)

Each issued and outstanding share of Company Common Stock (excluding shares cancelled pursuant to Section 2.01(b) and any Dissenting Shares to the extent provided in Section 2.04 but including all shares of Company Common Stock issued upon exercise of Company Options or Company Warrants occurring after the date of this Agreement and including all shares issuable upon conversion of any of the In the Money Company Warrants) shall be converted into the right to receive a number of shares of Parent Common Stock equal to: (A) 2,500,000, divided by (B) the sum of (1) the total number of shares of Company Common Stock outstanding at the Effective Time, and (2) the total number of shares of Company Common Stock issuable upon conversion of the In the Money Company Warrants assuming a cashless conversion at the closing price of Company Common Stock on the date of this Agreement, such quotient to be carried out to eight decimal points (the “Common Stock Exchange Ratio”); provided, however, that in no event shall Parent be required to issue more than an aggregate of 2,500,000 shares of Parent Common Stock as consideration for the Merger and the transactions contemplated thereby;

(ii)

The total number of shares of Parent Common Stock issuable in exchange for the Company Common Stock and shares underlying the In the Money Company Warrants shall be referred to herein collectively as the “Merger Consideration.” In no event shall the aggregate number of shares of Parent Common Stock to be issued or issuable hereunder in exchange for Company Common Stock and/or In the Money Company Warrants exceed, in the aggregate, 2,500,000 (or such lesser number if decreased in accordance with Section 2.04). Except as set forth in this Article II, no other amounts shall be payable with respect to such Company Common Stock or In the Money Company Warrants.

(d)

Cancellation and Retirement of Company Common Stock. As of the Effective Time, all shares of Company Common Stock issued and outstanding immediately prior to the Effective Time shall no longer be outstanding and shall automatically be cancelled and retired and shall cease to exist, and each holder of a certificate representing any such shares of Company Common Stock (collectively, the “Certificates”) shall, to the extent such Certificate represents such shares, cease to have any rights with respect thereto, except the right to receive the Merger Consideration (and cash in lieu of fractional shares of Parent Common Stock) to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with Section 2.02.

(e)

Cancellation and Retirement of In the Money Company Warrants. As of the Effective Time, all of the In the Money Company Warrants outstanding immediately prior to the Effective Time shall no longer be outstanding and shall be cancelled and retired and shall cease to exist, and each holder of an In the Money Warrant shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration (and cash in lieu of fractional shares of Parent Common Stock) to be issued or paid in consideration therefor upon surrender of such In the Money Warrant in accordance with Section 2.02.

(f)

Company Notes. At the Effective Time, Parent shall assume the due and punctual performance of all of the terms and conditions of each outstanding Company Note and each such Company Note shall, unless the conversion rights thereunder have previously expired, become convertible into the number of New Securities (as defined in the Company Notes) of Parent and at such Conversion Price (as defined in the Company Notes) as set forth therein. The “Company Notes” shall be the convertible promissory notes made by the Company listed in Section 2.01(f) of the Company Disclosure Schedule. The parties acknowledge that certain of the Company Notes automatically will convert, at the closing price of Parent Common Stock on the date hereof, to the right to receive Parent Common Stock at the Effective Time.

2.02	Exchange of Certificates.

(a)

Exchange Agent. As of the Effective Time, Parent shall enter into an agreement with such bank or trust company as may be designated by Parent (the “Exchange Agent”) which shall provide that Parent shall deposit with the Exchange Agent, for the benefit of the holders of Certificates and In the Money Company Warrants, for exchange in accordance with this Article II, certificates representing the shares of Parent Common Stock (such shares of Parent Common Stock, together with any dividends or distributions with respect thereto with a record date after the Effective Time and any cash payable in lieu of any fractional shares of Parent Common Stock being hereinafter referred to as the “Exchange Fund”) issuable pursuant to Section 2.01 in exchange for outstanding shares of Company Common Stock and In the Money Company Warrants.

(i)

Exchange Procedures. Promptly after the Effective Time, the Exchange Agent shall mail to each holder of record of Certificates and In the Money Company Warrants immediately prior to the Effective Time whose shares of Company Common Stock and/or In the Money Company Warrants were converted into shares of Parent Common Stock pursuant to Section 2.01(c) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates and/or In the Money Company Warrants shall pass only upon delivery of the Certificates and/or In the Money Company Warrants, as applicable, to the Exchange Agent, and which shall be in such form and have such other provisions as Parent may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates and/or In the Money Company Warrants in exchange for certificates representing shares of Parent Common Stock. Upon surrender of a Certificate and/or In the Money Company Warrants for cancellation (or indemnity reasonably satisfactory to Parent and the Exchange Agent, if any of such Certificates and/or In the Money Company Warrants are lost, stolen or destroyed) to the Exchange Agent together with such letter of transmittal, duly executed, the holder of such Certificate and/or In the Money Company Warrants shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Parent Common Stock which such holder has the right to receive in respect of all Certificates and/or In the Money Company Warrants surrendered by such holder pursuant to the provisions of this Article II (after taking into account all shares of Company Common Stock than held by such holder either directly or upon conversion of the In the Money Company Warrants in a cashless conversion), and the Certificates and/or In the Money Company Warrants, as applicable, so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of shares of Company Common Stock and/or In the Money Company Warrants which is not registered in the transfer records of the Company, a certificate representing the proper number of shares of Parent Common Stock may be issued to a transferee if the Certificate and/or In the Money Company Warrants, as applicable, is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer Taxes have been paid. Until surrender as contemplated by this Section 2.02(b), subject to the provisions of Section 6.02(h) (Dissenters Rights) each Certificate and In the Money Company Warrants, in each case, shall be deemed at any time after the Effective Time to represent only the Parent Common Stock into which the shares of Company Common Stock represented by such Certificate or In the Money Company Warrants have been converted as provided in this Article II and the right to receive upon such surrender cash in lieu of any fractional shares of Parent Common Stock as contemplated by this Section 2.02(b).

(ii)

Distributions with Respect to Unexchanged Shares. No dividends or other distributions with respect to Parent Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the shares of Parent Common Stock represented thereby, and no cash payment in lieu of fractional shares shall be paid to any such holder pursuant to this Section 2.02 until the surrender of such Certificate and/or In the Money Company Warrants, as applicable, in accordance with this Article II. Subject to the effect of applicable laws, following surrender of any such Certificate and/or In the Money Company Warrants, as applicable, there shall be paid to the holder of the certificate representing the whole shares of Parent Common Stock issued in exchange therefor without interest, (i) at the time of such surrender, the amount of any cash payable in lieu of any fractional share of Parent Common Stock to which such holder is entitled pursuant to this Section 2.02 and the amount of any dividends or other distributions with a record date after the Effective Time and a payment date subsequent to such surrender payable with respect to such whole shares of Parent Common Stock.

(iii)

No further Ownership Rights in Company Common Stock. All shares of Parent Common Stock issued upon conversion of shares of Company Common Stock and In the Money Company Warrants in accordance with the terms hereof, and all cash paid pursuant to this Section 2.02 in lieu of fractional shares, shall be deemed to have been issued in full satisfaction of all rights pertaining to such Company Common Stock and/or In the Money Company Warrants, and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Company Common Stock and In the Money Company Warrants which were outstanding prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Article II.

(iv)

No Fractional Shares. (i) No certificate or scrip representing fractional shares of Parent Common Stock shall be issued upon the surrender for exchange of Certificates and/or In the Money Company Warrants, and such fractional share interests shall not entitle the owner thereof to vote or to any rights of a stockholder of Parent. In lieu of such issuance of fractional shares, Parent shall pay each holder of Certificates and In the Money Company Warrants an amount in cash equal to the product obtained by multiplying (a) the fractional share interest to which such holder would otherwise be entitled (after taking into account all shares of Company Common Stock held immediately prior to the Effective Time by such holder) by (b) the average of the closing sale prices for a share of Parent Common Stock on the OTC Bulletin Board for the ten trading days immediately preceding the date of the Effective Time.

(b)

As soon as reasonably practicable after the determination of the amount of cash, if any, to be paid to holders of Certificates and/or In the Money Company Warrants, as applicable, with respect to any fractional share interests, the Exchange Agent shall make available such amounts to such holders of Certificates and/or In the Money Company Warrants, subject to and in accordance with the terms of this Section 2.02.

(c)

Termination of Exchange Fund. Any portion of the Exchange Fund deposited with the Exchange Agent pursuant to this Section 2.02 which remains undistributed to the holders of the Certificates and/or In the Money Company Warrants six months after the Effective Time shall be delivered to Parent, upon demand, and any holders of Certificates and/or In the Money Company Warrants who have not theretofore complied with this Article II shall thereafter look only to Parent and only as general creditors thereof for payment of their claim for Parent Common Stock, cash in lieu of fractional shares of Parent Common Stock and any dividends or distributions with respect to Parent Common Stock to which such holders may be entitled pursuant to this Article II.

(d)

No Liability. None of Parent, Merger Sub, the Company or the Exchange Agent shall be liable to any Person in respect of any shares of Parent Common Stock (or dividends or distributions with respect thereto) or cash from the Exchange Fund delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Certificates and/or In the Money Company Warrants shall not have been surrendered prior to three years after the Effective Time of the Merger, or immediately prior to such earlier date on which any Merger Consideration, any cash in lieu of fractional shares of Parent Common Stock or any dividends or distributions with respect to Parent Common Stock would otherwise escheat to or become the property of any Governmental Entity, any such Merger Consideration or cash shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

(e)	Investment of Exchange Fund. The Exchange Agent shall invest any cash included in the Exchange Fund, as directed by Parent on a daily basis. Any interest and other income resulting from such investments shall be paid to Parent.

(f)

Adjustment Provisions. In the event Parent changes (or establishes a record date for changing) the number of shares of Parent Common Stock issued and outstanding prior to the Effective Time as a result of, including, without limitation, a forward or reverse stock split, stock dividend, recapitalization or similar transaction with respect to the outstanding Parent Common Stock and the record date therefor shall be prior to the Effective Time, the Common Stock Exchange Ratio shall be proportionately adjusted. If between the date hereof and the Effective Time, Parent shall merge, be acquired or consolidated with, by or into any other corporation (a “Business Combination”) and the terms thereof shall provide that Parent Common Stock shall be converted into or exchanged for the shares of any other corporation or entity, then provision shall be made as part of the terms of such Business Combination so that security holders of the Company who would be entitled to receive shares of Parent Common Stock pursuant to this Agreement shall be entitled to receive, in lieu of each share of Parent Common Stock issuable to such security holders as provided herein, the same kind and amount of securities or assets as shall be distributable upon such Business Combination with respect to one share of Parent Common Stock (provided that nothing herein shall be construed so as to release the acquiring entity in any such Business Combination from its obligations under this Agreement as the successor to Parent).

2.03 Treatment of Company Options and Company Warrants. Parent shall not assume any options to purchase shares of Company Common Stock (the “Company Options”), even if such Company Options are outstanding immediately prior to the Effective Time and are fully vested and exercisable immediately prior to the Effective Time. All Company Options shall have been exercised or terminated prior to the Closing Date. The Company shall have taken all necessary action to implement and carry out the provisions of this Section 2.03, including, without limitation, taking the actions described in Section 6.02(e).

Section 2.03 of the Company Disclosure Letter sets forth a list of the outstanding “in the money” warrants to purchase shares of Company Common Stock (the “In the Money Company Warrants”). At the Effective Time, the In the Money Company Warrants shall automatically convert into the right to receive a portion of the Merger Consideration as provided in Section 2.01 above. Except for the obligation to grant a portion of the Merger Consideration to holders of the In the Money Company Warrants, Parent shall not assume either the In the Money Company Warrants or the warrants to purchase shares of Company Common Stock (the “Company Warrants”), even if such Company Warrants are outstanding immediately prior to the Effective Time and are fully vested and exercisable immediately prior to the Effective Time. The Company shall have taken all necessary action to implement and carry out the provisions of this Section 2.03, including, without limitation, taking the actions described in Section 6.02(e).

2.04 Dissenting Shares.

(a) Subject to the provisions of Section 6.02(g) and notwithstanding any provision of this Agreement to the contrary, the shares of any holder of Company Common Stock who has demanded and perfected appraisal rights of such shares in accordance with Delaware Law and who, as of the Effective Time of the Merger, has not effectively withdrawn or lost such appraisal rights ("Dissenting Shares") shall not be converted into or represent a right to receive Parent Common Stock pursuant to Section 2.01(c), but the holder thereof shall only be entitled to such rights as are granted by Delaware Law, and the total number of shares of Parent Common Stock issuable as Merger Consideration as provided in Section 2.01(c) shall be proportionately decreased.

(b) Notwithstanding the foregoing, if any holder of shares of Company Common Stock who demands appraisal of such shares under Delaware Law shall effectively withdraw the right to appraisal, then, as of the later of the Effective Time and the occurrence of such event, such holder's shares shall automatically be converted into and represent only the right to receive Parent Common Stock, without interest thereon, upon surrender of the Certificate representing such shares as provided in Section 2.01(c), and the total number of shares of Parent Common Stock issuable as Merger Consideration as provided in Section 2.01(c) shall be proportionally increased to the extent such number was previously decreased pursuant to Section 2.05(a) above with respect to such shares.

(c) The Company shall give Parent (i) prompt notice of any written demands for appraisal of any shares of Company Common Stock, withdrawals of such demands, and any other instruments served pursuant to Delaware Law and received by the Company which relate to any such demand for appraisal and (ii) the opportunity to participate in all negotiations and proceedings which take place prior to the Effective Time with respect to demands for appraisal under Delaware Law. The Company shall not, except with the prior written consent of Parent or as may be required by applicable law, voluntarily make any payment with respect to any demands for appraisal of the Company Common Stock or offer to settle or settle any such demands.

2.05 Withholding Rights. Each of Parent and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by Parent or the Surviving Corporation, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such holder in respect of which such deduction and withholding was made by Parent or the Surviving Corporation, as the case may be.

ARTICLE III.

Neither Parent nor any of its Subsidiaries has any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise) required by generally accepted accounting principles as applied in the United States to be recognized or disclosed on a consolidated balance sheet of Parent and its Subsidiaries or in the notes thereto, except (i) liabilities reflected in the audited consolidated balance sheet of Parent as of December 31, 2006 and (ii) liabilities incurred since December 31, 2006, in the ordinary course of business consistent with past practice.

The Form S-4 shall comply as to form in all material respects with the requirements of the Securities Act and the rules and regulations promulgated thereunder, except that no representation is made by Parent or Merger Sub with respect to statements made or incorporated by reference therein based on information supplied in writing by the Company specifically for inclusion or incorporation by reference therein.

(f)

Absence of Certain Changes or Events. Since March 31, 2008, there is not and has not been: (i) any Material Adverse Change with respect to Parent; (ii) any condition, event or occurrence which, individually or in the aggregate, could reasonably be expected to have a Material Adverse Effect or give rise to a Material Adverse Change with respect to Parent; (iii) any condition, event or occurrence which, individually or in the aggregate, could reasonably be expected to prevent or materially delay the ability of Parent and Merger Sub to consummate the transactions contemplated by this Agreement or perform their respective obligations hereunder.

The businesses of Parent and its Subsidiaries are not being conducted in violation of any law (domestic or foreign), ordinance or regulation of any Governmental Entity, except for possible violations which, individually or in the aggregate, do not and would not have a Material Adverse Effect with respect to Parent.

(h)	Interim Operations of Merger Sub. Merger Sub was formed on July 10, 2008 solely for the purpose of engaging in the transactions contemplated hereby, has engaged in no other business activities and has conducted its operations only as contemplated hereby.

(i)	Required Vote. This Agreement has been approved by Parent, as the sole stockholder of Merger Sub. No other vote of holders of any class or series of securities of Parent or Merger Sub is necessary to approve this Agreement, the Merger and the transactions contemplated hereby.

(j)

Taxes. Parent has timely filed all Tax Returns required to be filed by it, each such Tax Return has been prepared in compliance with all applicable laws and regulations, and all such Tax Returns are true, accurate and complete in all respects.

Parent has made accruals for Taxes on the Parent SEC Financial Statements that are adequate to cover any Tax liability of Parent determined in accordance with generally accepted accounting principles through the date of the applicable Parent SEC Financial Statements, and any Taxes of Parent arising after the date of the most recent Parent SEC Financial Statements and at or before the Effective Time of the Merger have been or will be incurred in the ordinary course of Parent's business.

Parent has not granted any outstanding extensions of the time in which any Tax may be assessed or collected by any Tax authority. There is no action, suit, proceeding, or audit with respect to any Tax now in progress, pending or, to the knowledge of Parent, threatened against or with respect to Parent.

Neither Parent nor any of its Subsidiaries has ever filed or been included in a combined, consolidated or unitary Tax Return other than with respect to a group of which Parent was the common parent. Parent is neither a party to nor bound by any Tax sharing agreement or Tax allocation agreement. Neither Parent nor any of its Subsidiaries is presently liable, nor does Parent or any of its Subsidiaries have any potential liability, for the Taxes of another person (i) under Treasury Regulations Section 1.1502-6 or comparable provision of state, local or foreign law, except with respect to a group of which Parent was the common parent, (ii) as transferee or successor, or (iii) by contract or indemnity or otherwise (other than pursuant to contracts entered into with customers, vendors, real property lessors, or other third parties the principal purpose of which is not to address Tax matters).

Parent will not be required, as a result of a change in method of accounting for any period ending on or before or including the Effective Time of the Merger, to include any adjustment under Section 481(c) of the Code (or any similar or corresponding provision or requirement under any other Tax law) in Taxable income for any period ending on or after the Effective Time of the Merger. Parent will not be required to include any item of income in Taxable income for any Taxable period (or portion thereof) ending after the Closing Date as a result of any (i) prepaid amount received on or prior to the Closing Date, or (ii) "closing agreement" described in Section 7121 of the Code (or any similar or corresponding provision of any other Tax law). Parent has never been either a "distributing corporation" or a "controlled corporation" in connection with a distribution of stock qualifying for Tax-free treatment, in whole or in part, pursuant to Section 355 of the Code. Parent is not and has not been a United States real property holding corporation within the meaning of Code Section 897(c)(2), during the applicable period specified in Code Section 897(c)(1)(A)(ii). For purposes of this Section 3.02(j), references to Parent shall be deemed to include Parent and all of its Subsidiaries except where the context indicates otherwise.

(e)

No Circular Recovery. The obligations of the Parent and the Surviving Corporation in this Section 5.04 are subject to the condition that each Indemnified Party will not make any claim for indemnification against the Parent, the Surviving Corporation or the Company by reason of the fact that such Indemnified Party was a controlling person, director, employee or representative of the Company or the Surviving Corporation or was serving as such for another Person at the request of the Company (whether such claim is for losses of any kind or otherwise and whether such claim is pursuant to any statute, organizational document, contractual obligation or otherwise) with respect to any claim brought by the Parent or its affiliates relating to this Agreement that is finally and successfully adjudicated against such Indemnified Party.

Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

7.05

Procedure for Termination, Amendment, Extension or Waiver. A termination of this Agreement pursuant to Section 7.01, an amendment of this Agreement pursuant to Section 7.03 or an extension or waiver pursuant to Section 7.04 shall, in order to be effective, require in the case of any party hereto an action by its Board of Directors or a duly-authorized designee of its Board of Directors.

8.08

Governing Law; Consent to Jurisdiction; Waiver of Jury Trial. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws.
