W I T N E S S E T H:

WHEREAS, the respective Boards of Directors of Pubco, TAC and Envirosystems have deemed it advisable and in the best interests of their respective corporations and stockholders that Pubco, TAC and Envirosystems engage in a business combination to advance their respective long-term strategic business interests; and

WHEREAS, in furtherance thereof, the Boards of Directors of each of Pubco, TAC and Envirosystems have, among other items, approved this Agreement and the Merger of TAC into Envirosystems with Envirosystems continuing as the surviving corporation and certain stockholders of Envirosystems receiving shares of Pubco Common Stock in exchange for their Envirosystems capital stock, all upon the terms and subject to the conditions set forth in this Agreement and in accordance with the provisions of the applicable laws, and

WHEREAS, the Board of Directors of Envirosystems has determined to recommend to its stockholders the approval and adoption of this Agreement and the Merger; and

WHEREAS, the Boards of Directors of Pubco and TAC have determined to recommend to their respective stockholders the approval and adoption of this Agreement and the Merger; and

WHEREAS, Pubco, as the sole stockholder of EnviroSystems Holdings, Inc., a Delaware corporation and wholly-owned subsidiary of Pubco ("Pubco Sub"), and Pubco Sub, as the sole shareholder of TAC, have approved this Agreement and the Merger; and

WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement for Pubco to enter into this Agreement (i) The Ferguson Living Trust UTD 8/13/74 (the "Trust"), the owner of 1,461,117 shares of Envirosystems Preferred Stock, which represents approximately 57.8% of the issued and outstanding Envirosystems Preferred Stock, and (ii) MV Nanotech, the owner of 850,000 shares of Envirosystems Common Stock, which represents 83% of the issued and outstanding Envirosystems Common Stock (the Trust and MV Nanotech are hereinafter defined as the "Envirosystems Principal Shareholders"), have entered into the Voting Agreement pursuant to which the Envirosystems Principal Shareholders have agreed to vote all of their respective shares of Envirosystems Common Stock and Envirosystems Preferred Stock in favor of this Agreement and the Merger; and

provided, however, that notwithstanding anything to the contrary provided herein or elsewhere, in no event shall any shares of Pubco Common Stock issued upon conversion of the Bridge Loans, if any, reduce the Envirosystems 40% Interest as a result of the conversion of their Envirosystems Preferred Stock into Pubco Common Stock, and the number of shares of Pubco Common Stock to be issued to holders of Envirosystems Preferred Stock shall be increased such that the aggregate number represents forty percent (40%) of the issued and outstanding Pubco Common Stock immediately following the Merger Closing after giving effect to shares issued upon conversion of the Bridge Loans, if any, and the issuances referred to in 2.5(b)(1), (2) and (3) referred to above.

Each certificate evidencing ownership of shares of TAC Common Stock shall evidence ownership of such shares of capital stock of the Surviving Corporation.

(d) ENVIROSYSTEMS' OPTIONS AND WARRANTS.

(i) At the Effective Time, the obligations of Envirosystems under any Envirosystems stock options and/or warrants to purchase Envirosystems Preferred Stock outstanding at the Effective Time and certain other options or warrants, all of which are set forth together with their respective exercise prices on Schedule 2.5(d)(i) of this Agreement (collectively, "Envirosystems Options and Warrants"), shall be satisfied out of the Escrow Account established pursuant to Section 2.11, and, thereafter, upon exercise, each holder thereof shall receive the number of shares of Pubco Common Stock equal to the number of shares of Pubco Common Stock that such holder would have received in the Merger if such person exercised the Envirosystems Options and/or Warrants held by such person immediately prior to the Effective Time or as otherwise specified on Schedule 2.5(d)(i). The per share exercise price under each such Envirosystems Options and Warrants shall be as set forth on Schedule 2.5(d)(i). At the Effective Time, all Envirosystems options and/or warrants to purchase Envirosystems Common Stock outstanding at the Effective Time and not listed in Schedule 2.5(d)(i) shall be automatically cancelled and extinguished.

(ii) As soon as practicable after the Effective Time of the Merger, Envirosystems shall deliver to the holders of the Envirosystems Options and Warrants appropriate notices setting forth such holders’ rights pursuant to the applicable Pubco warrants and stock options issuable with respect thereto to the extent required by the terms of such warrants and stock options.

(e) ADJUSTMENTS TO THE PUBCO PREFERRED CONVERSION RATIO. The Pubco Preferred Conversion Ratio shall be adjusted as follows:

(i) to reflect the appropriate effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Pubco Common Stock), reorganization, recapitalization, reclassification or other like change with respect to Pubco Common Stock having a record date on or after the date hereof and prior to the Effective Time; and

(ii) if, as of the earlier of the Effective Time or December 31, 2005, the sum of Envirosystems Debt outstanding , as set forth on Schedule 2.5(e)(ii) hereto, including ESI Legal Fees (as defined in Section 8.7 of this Agreement) (not including outstanding principal and accrued and unpaid interest payable pursuant to the Bridge Loans, the Hoffman Payment and accrued and unpaid fees payable to Envirosystem’s auditors), less all cash on hand and finished goods inventory up to a maximum of $50,000 of inventory, exceeds $2,050,000 (such amount in excess of $2,050,000 being referred to herein as "Excess Debt Consideration") then, the Pubco Preferred Conversion Ratio shall be adjusted so that the Envirosystems 40% Interest shall be reduced by such number of shares of Pubco Common Stock as shall equal the quotient obtained by dividing (i) the Excess Debt Consideration by (ii) the Pubco PIPE Share Price.

(f) DISSENTING ENVIROSYSTEMS STOCKHOLDERS. Any holder of shares of Envirosystems Preferred Stock (and/or Envirosystems Common Stock) who perfects their dissenters’ rights in accordance with and as contemplated by applicable California Law and Nevada Law shall not be converted into Pubco Common Stock, but instead shall be entitled to receive such consideration as determined pursuant to the applicable provisions of California Law and Nevada Law upon surrender to Pubco of the certificate or certificates representing the shares for which payment is being made (the "Dissenters’ Compensation"). In the event that a dissenting stockholder of Envirosystems fails to perfect, or effectively withdraws or loses, its right to appraisal and payment for its shares under California Law and Nevada Law, Pubco shall issue and deliver the number of shares of Pubco Common Stock to which such holder of shares of Envirosystems Preferred Stock would otherwise be entitled pursuant to the provisions of this Article II (without interest) upon surrender by such holder of the certificate or certificates representing such shares held by such holder. Notwithstanding anything to the contrary provided herein or elsewhere in this Agreement, in the event any Dissenters' Compensation is paid to any Person, the aggregate of all Dissenters' Compensation shall reduce Envirosystems 40% Interest by subtracting therefrom a number of Pubco shares equal to the aggregate Dissenters' Compensation divided by the Pubco PIPE Share Price.

(g) BRIDGE LOAN CONVERSION. MV Nanotech shall have the option to convert the unpaid principal amount of the Bridge Loans and all accrued and unpaid interest

thereon into such number of shares of Pubco Common Stock as shall be determined by dividing the total of the unpaid principal amount of the Bridge Loans and accrued and unpaid interest to be converted by the Pubco Pipe Financing Price. MV Nanotech may deliver a notice to Envirosystems of such intent to convert (a “Conversion Notice”) at any time prior to the Closing Date which such Conversion Notice shall specify the amount of unpaid principal and accrued and unpaid interest of Bridge Loans. Upon a conversion of all or a portion of the Bridge Loans by MV Nanotech pursuant to this Section 2.5(g), the number of shares of Pubco Common Stock constituting the Envirosystems 40% Interest shall be adjusted in accordance with Section 2.5(b) above. Such shares of Pubco Common Stock which are the subject of such Conversion Notice shall be issued to MV Nanotech at the Closing. All amounts of unpaid principal and accrued and unpaid interest not so converted shall be paid in cash to MV Nanotech at the Closing.

(h) FRACTIONAL SHARES. No certificates representing fractional shares of Pubco Common Stock will be issued as a result of the Merger. Each holder of shares of Envirosystems Preferred Stock exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Pubco Common Stock shall receive, in lieu thereof, cash (rounded to the nearest whole cent and without interest) in an amount equal to such fractional part of a share of Pubco Common Stock, multiplied by the Pubco PIPE Share Price. No such holder will be entitled to dividends, voting rights, or any other rights as a stockholder in respect of any fractional shares.

2.6 SURRENDER OF CERTIFICATES.

2.6.1 EXCHANGE AGENT. Pubco's transfer agent or such other person as ESI and Pubco shall so select shall act as the exchange agent (the "Exchange Agent") in the Merger.

(e) REQUIRED WITHHOLDING. Each of the Exchange Agent, Pubco and the Surviving Corporation shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any holder or former holder of Envirosystems Preferred Stock such amounts as may be required to be deducted or withheld there from under the Code or under any provision of state, local or foreign tax law or under any other applicable Law. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes under this Agreement as having been paid to the person to whom such amounts would otherwise have been paid.

(f) NO LIABILITY. Notwithstanding anything to the contrary, neither the Exchange Agent, Pubco, the Surviving Corporation nor any party hereto shall be liable to a holder of shares of Pubco Common Stock, Envirosystems Common Stock and Envirosystems Preferred Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

Schedule 3.16(d) also identifies each Envirosystems Plan which constitutes an "employee pension benefit plan" ("Envirosystems Pension Plan") or an "employee welfare benefit plan" ("Envirosystems Welfare Plan"), as such terms are defined in the Employee Retirement Income Security Act of 1974, as amended, and the rules and regulations promulgated thereunder ("ERISA").

No Envirosystems Plans is a "multiemployer plan," as such term is defined in ERISA, or is subject to Title IV of ERISA.

Envirosystems has the right to amend or terminate, without the consent of any other person, each Envirosystems Plan, except as proscribed by law.

Each Envirosystems Pension Plan has been determined by the IRS to be qualified under Section 401(a) of the Code, and each such plan remains so qualified; and, no facts or circumstances exist which could result in the revocation of such qualification.

With respect to each Envirosystems Plan, all reports, returns and similar documents required to be filed with any governmental agency or distributed to any participant have been duly or timely filed or distributed. No facts or circumstances exist which might give rise to any liability of Envirosystems to the Pension Benefit Guaranty Corporation or any successor agency (the "PBGC") or which could reasonably be anticipated to result in any claims being made against Envirosystems, Pubco or any Subsidiary thereof by the PBGC. No facts or circumstances exist which might give rise to any liability of any Envirosystems Plan, Envirosystems, Pubco or any Subsidiary thereof to any other Person. Envirosystems has paid all amounts required under applicable Law, any Envirosystems Pension Plan and any Envirosystems Welfare Plan to be paid as a contribution to each Envirosystems Pension Plan and Envirosystems Welfare Plan through the date hereof. Envirosystems set aside adequate reserves to meet contributions which are not yet due

under any Envirosystems Pension Plan or Envirosystems Welfare Plan. Neither Envirosystems, any of its Subsidiaries nor any other Person has engaged in any transaction or taken any other action with respect to any Envirosystems Plan which would subject Envirosystems, Pubco or any Subsidiary thereof to: (i) any Tax, penalty or liability for prohibited transactions under ERISA or the Code; (ii) any Tax under Code Sections 4971, 4972, 4976, 4977 or 4979; or (iii) a penalty under ERISA Sections 502(c) or 502(l).

Each Envirosystems Welfare Plan which is a group health plan within the meaning of Code Section 5000(b)(1) complies in all material respects with and in each and every case has complied in all material respects with the applicable requirements of Code Section 4980B and Part 6 of Title I of ERISA and the Health Insurance Portability and Accountability Act of 1996. No Envirosystems Welfare Plan is a multi-employer welfare arrangement as defined in Section 3(40) of ERISA.

If this Agreement is terminated pursuant to, and in accordance with, this Section 7.5, written notice thereof shall promptly be given by the party electing such termination to the other party and, subject to the expiration of the cure periods provided in clauses (iii) and (iv) above, if any, this Agreement shall terminate without further actions by the parties and, except as provided in this Section 7.5, no party shall have any further obligations under this Agreement; provided, however, that any termination of this Agreement pursuant to this Section 7.5 shall not relieve any party from any liability for any intentional or willful breach or violation hereof; provided, further that a breach of Section 5.9 shall not be deemed an intentional or willful breach if the Board of Directors

No Escrow Shares, however, will be available to compensate Indemnified Parties, unless and until the aggregate Losses incurred by all Indemnified Parties resulting from one or more Damage Events exceeds $100,000 (the "Damage Threshold").

All claims for Damage Event must be brought, if at all, within one (1) year following the Closing Date.

(c) No Escrow Shares shall be released by the Escrow Agent either to the holders of the Escrow Shares and/or to an Indemnified Party other than in accordance with and pursuant to the terms of the Escrow Agreements.

(d) To the extent that any terms of this Agreement are inconsistent with the provisions of the Escrow Agreement , the terms of this Agreement shall be controlling.
