Subject to the conditions of this Agreement, as soon as practicable on or after the Closing Date (as hereinafter defined), the parties hereto shall cause the Merger to be consummated by filing articles of merger (the “Articles of Merger”) with the Secretary of State of the Commonwealth of Pennsylvania in accordance with the applicable provisions of the PBCL and the certificate of merger (“Certificate of Merger”) with the Secretary of State of the State of Delaware in accordance with the applicable provisions of the DGCL (the time of such later filing, or such later time as may be agreed in writing by PRWT and KBL and specified in the Articles of Merger being the “Effective Time”). Unless this Agreement shall have been terminated pursuant to Section 8.1, the consummation of the transactions contemplated by this Agreement (the “Closing”), other than the filing of the Articles of Merger and Certificate of Merger, shall take place at the offices of Xxxxxxxx Xxxxxx, counsel to KBL, 000 Xxxxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000-0000 at a time and date to be specified by the parties, which shall be no later than the fifth (5th) business day after the satisfaction or waiver of the conditions set forth in Article VI, or at such other time, date and location as the parties hereto agree in writing (the “Closing Date”). Closing signatures may be transmitted by facsimile or by emailed PDF file.

1.3 Effect of the Merger. At the Effective Time, the effect of the Merger shall be as provided in this Agreement and the applicable provisions of the DGCL and PBCL and other applicable provisions of Delaware and Pennsylvania law (collectively, the “Applicable Law”). Without limiting the generality of the foregoing, and subject thereto, at the Effective Time all the property, rights, privileges, powers and franchises of KBL shall vest in Merger Sub, and all debts, liabilities and duties of KBL shall become the debts, liabilities and duties of Merger Sub, and Merger Sub shall continue as a wholly owned subsidiary of the Surviving Pubco.

1.4 Governing Documents. At the Effective Time,

(a) the Articles of Incorporation of PRWT shall be amended and restated in a manner to be mutually and reasonably agreed upon by PRWT and KBL and appropriate for a public company and shall become the Articles of Incorporation of the Surviving Pubco;

(b) the Bylaws of PRWT shall be amended and restated in a manner to be mutually and reasonably agreed upon by PRWT and KBL and appropriate for a public company and shall become the Bylaws of the Surviving Pubco;

(c) the Articles of Incorporation of Merger Sub in the form attached hereto as Exhibit A shall remain the Articles of Incorporation of Merger Sub; and

(d) the Bylaws of Merger Sub in the form attached hereto as Exhibit B shall remain the Bylaws of Merger Sub.

1.5 Effect on KBL Securities. Subject to the terms and conditions of this Agreement, at the Effective Time, by virtue of the Merger and this Agreement and without any action on the part of KBL or the holders of any of the securities of KBL, the following shall occur:

(a) Conversion of KBL Common Stock. Other than any shares to be canceled pursuant to Section 1.5(b) and subject to adjustment in accordance with Section 1.5(c), each share of common stock, par value $.0001, of KBL (“KBL Common Stock”) issued and outstanding immediately prior to the Effective Time will be automatically converted into one (1) share of common stock of PRWT (“PRWT Common Stock”). Following the Merger, each certificate evidencing KBL Common Stock shall automatically be deemed to represent the same number of shares of PRWT Common Stock without surrender or exchange of such certificate. Following the Merger, all shares of KBL Common Stock that are not certificated and which are converted into PRWT Common Stock in the Merger shall be deemed replaced by the same number of shares of uncertificated PRWT Common Stock on the books and records of the Surviving Pubco’s transfer agent and all other entities that maintain records with respect thereto. The shares of PRWT Common Stock that would otherwise be issuable pursuant to this Section 1.5(a) to Persons who hold Dissenting Shares (as defined in Section 1.15) and exercise their appraisal rights pursuant to applicable Delaware Law shall not be issued to such Persons and shall be canceled.

(b) Cancellation of Treasury and PRWT-Owned Stock. Each share of KBL Common Stock held by KBL or owned by PRWT or any direct or indirect wholly owned subsidiary of KBL or PRWT immediately prior to the Effective Time shall be canceled and extinguished without any conversion or payment in respect thereof.

(c) Adjustments to Exchange Ratios. The numbers of PRWT Common Stock that the holders of KBL Common Stock (and the number of PRWT Warrants and PRWT Units that holders of KBL Warrants and KBL Units) are entitled to receive as a result of the Merger shall be equitably adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into PRWT Common Stock or KBL Common Stock), extraordinary cash dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to PRWT Common Stock or KBL Common Stock occurring on or after the date hereof and prior to the Effective Time except that no such adjustment shall be made as a result of the recapitalization provided for in Section 1.6.

(d) No Fractional Shares. No fraction of a share of PRWT Common Stock will be issued by virtue of the Merger or the transaction contemplated hereby, and each holder of shares of KBL Common Stock who would otherwise be entitled to a fraction of a share of PRWT Common Stock (after aggregating all fractional shares of PRWT Common Stock that otherwise would be received by such holder) shall be deemed to receive from the Surviving Pubco, in lieu of such fractional share, one (1) share of PRWT Common Stock.

(e) Conversion of KBL Warrants. Subject to adjustment in accordance with Section 1.5(c), each warrant (“KBL Warrant”) to purchase shares of KBL Common Stock issued and outstanding immediately prior to the Effective Time shall be automatically converted into a warrant (“PRWT Warrant”) to purchase the equivalent number of shares of PRWT Common Stock having terms and conditions substantially identical in all material respects to the terms and conditions pertaining to the KBL Warrants. The PRWT Warrants shall be governed by the Warrant Agreement dated July 19, 2007 between KBL and Continental Stock Transfer & Trust PRWT (“Continental”), as Warrant Agent. Following the Merger, each certificate evidencing KBL Warrants shall automatically be deemed to represent the same number of PRWT Warrants without surrender or exchange of such certificate. Following the Merger, all KBL Warrants that are not certificated shall be deemed replaced by the same number of uncertificated PRWT Warrants on the books and records of the Surviving Pubco’s transfer agent and all other entities that maintain records with respect thereto.

(f) Conversion of KBL Units. Subject to adjustment in accordance with Section 1.5(c), each unit (“KBL Unit”) consisting of one (1) share of KBL Common Stock and one (1) KBL Warrant issued and outstanding immediately prior to the Effective Time shall be automatically converted into a unit (“PRWT Unit”) consisting of one (1) shares of PRWT Common Stock and (1) PRWT Warrant. Following the Merger, each certificate evidencing KBL Units shall automatically be deemed to represent the same number of PRWT Units without surrender or exchange of such certificate. Following the Merger, all KBL Units that are not certificated shall be deemed replaced by the same number of uncertificated PRWT Units on the books and records of the Surviving Pubco’s transfer agent and all other entities that maintain records with respect thereto.

(g) No Further Ownership Rights in KBL Stock. All PRWT Common Stock, PRWT Warrants and PRWT Units deemed issued to holders of KBL securities upon consummation of the Merger and conversion of the KBL securities shall be deemed to have been issued in full satisfaction of all rights pertaining to the corresponding outstanding KBL securities and there shall be no further registration of transfers on the records of the Surviving Pubco of the KBL securities that were outstanding immediately prior to the Effective Time.

(h) No Liability. Notwithstanding anything to the contrary in this Article I, no party hereto shall be liable to a holder of KBL securities or PRWT Common Stock for any amount properly paid to a public official pursuant to any applicable abandoned property, escheat or similar law.

1.6 PRWT Recapitalization. On or before the Closing Date, PRWT shall recapitalize so that there are eleven million, nine hundred and fifty thousand (11,950,000) shares of a single class of PRWT Common Stock issued and outstanding immediately prior to the Closing, owned by the Stockholders as set forth in Schedule 1.6 (the “Stockholder Shares”); provided, however, that the foregoing number of shares of PRWT Common Stock shall be subject to adjustment in accordance with Section 1.7, below. No other shares of PRWT Common Stock shall be outstanding immediately prior to the Closing except as provided for in this Agreement.

1.7 Net Debt and Adjustment of Merger Shares.

(a) The term “Net Debt” shall mean PRWT’s combined consolidated indebtedness (i.e., all indebtedness for borrowed money and capitalized leases and equivalents and other obligations evidenced by promissory notes or similar instruments, as well as cash overdrafts excluding any costs or expenses incurred by PRWT or any subsidiary thereof in initially implementing and establishing compliance with the Xxxxxxxx-Xxxxx Act of 2002 or other similar rules and regulations, less PRWT’s combined consolidated cash and cash equivalents, including all short-term money market instruments and treasury bills and similar instruments. From the date hereof through the Closing, PRWT shall service all indebtedness, payables and receivables in the ordinary course of business, consistent with past practice.

(b) PRWT shall not incur any debt, other than in the ordinary course of business, during the period from the date three business days prior to the Closing Date and the Closing Date.

(c) From the date hereof through the Closing Date, on or before the 5th day of each calendar month, PRWT shall deliver to KBL a written statement of PRWT’s Net Debt as of the end of the immediately preceding calendar month (“Periodic Net Debt Statement”), which shall (i) provide such detailed information as may be reasonably requested by KBL prior to such date, (ii) be derived utilizing generally accepted accounting principles, consistent with PRWT’s historical practice and (iii) be certified as being true and complete by PRWT’s Chief Executive Officer and Chief Financial Officer.

(d) On the third business day prior to the scheduled Closing Date, PRWT shall deliver to KBL and PRWT’s auditors (“Independent Accountant”) a written statement of the estimate of PRWT’s Net Debt as of the close of business of the business day immediately prior to the delivery (“Estimated Net Debt Amount”), which shall (i) provide such detailed information as may be reasonably requested by KBL prior to such date, (ii) be derived utilizing generally accepted accounting principles, consistent with PRWT’s historical practice and (iii) be certified as being true and complete by PRWT’s Chief Executive Officer and Chief Financial Officer.

(e) If PRWT’s Estimated Net Debt Amount is less than $45,000,000, as determined in accordance with this Agreement, the aggregate number of Stockholder Shares shall be increased (“Stockholder Shares Increase Amount”) by an amount equal to the Net Debt Surplus divided by $7.85. “Net Debt Surplus” shall mean the amount by which $45,000,000 exceeds the Estimated Net Debt Amount. As an example, if the Estimated Net Debt Amount is $44,000,000, the Net Debt Surplus will be $1,000,000, the Stockholder Shares Increase Amount will be $1,000,000 divided by $7.85, or 127,389 shares (and an aggregate of 12,077,389 Stockholder Shares will be issued under Section 1.6).

(f) If PRWT’s Estimated Net Debt Amount is more than $45,000,000, as determined in accordance with this Agreement, subject to the limitations set forth in Section 1.7(i) hereof, the aggregate number of Stockholder Shares issued at Closing shall be decreased (“Stockholder Shares Decrease Amount”) by an amount equal to the Net Debt Excess divided by $7.85. “Net Debt Excess” shall mean the amount by which the Estimated Net Debt Amount exceeds $45,000,000. As an example, if the Estimated Net Debt Amount is $46,000,000, the Net Debt Excess will be $1,000,000, the Stockholders Shares Decrease Amount will be $1,000,000 divided by $7.85, or 127,389 shares (and an aggregate of 11,822,611 Stockholders Shares will be issued under Section 1.6). Notwithstanding anything herein to the contrary, the Stockholder Shares Decrease Amount shall not exceed the number of Escrow Shares.

(g) As soon as practicable after the Closing, but not later than sixty (60) days after the Closing, the Representative (as defined in Section 1.12(b)) shall use its commercially reasonable best efforts to deliver to the Committee a statement (the “Closing Net Debt Statement”) showing, in reasonable detail, the calculation of PRWT’s Net Debt as of the Closing (the “Closing Net Debt Amount”). The Committee and PRWT shall cooperate with the Representative in connection with the preparation of the Closing Net Debt Statement. If the Representative does not receive written notice from the Committee disputing the Closing Net Debt Statement within the fifteen (15) day period mentioned in Section 1.7(k) below, then the Closing Net Debt Statement shall become final and binding on the parties. The costs and expenses of the preparation of the Closing Net Debt Statement shall be borne by the Surviving Pubco.

(h) If the Closing Net Debt Amount (as finally determined, pursuant to Section 1.7(g) or (k), as applicable) is less than the Estimated Net Debt Amount, the Surviving Pubco shall issue to the Stockholders, within ten (10) days after the final determination of the Closing Net Debt Amount, shares of PRWT Common Stock equal to (x) the amount by which the Closing Net Debt Amount is less than the Estimated Net Debt Amount divided by (y) $7.85. If the Closing Net Debt Amount is greater than the Estimated Net Debt Amount, the Surviving Pubco shall be entitled, subject to the limitations set forth in Section 1.7(i) hereof, to withdraw, within ten (10) days after the final determination of the Closing Net Debt Amount, the amount of Escrow Shares (as defined in Section 1.10) equal to (x) the amount by which the Closing Net Debt Amount exceeds the Estimated Net Debt Amount divided by (y) $7.85. If the Closing Net Debt Amount is equal to the Estimated Net Debt Amount, there shall be no adjustment.

(i) Notwithstanding anything herein to the contrary, any downward adjustment of shares of PRWT Common Stock to be issued to the Stockholders pursuant to either Section 1.7(f) or (h) shall serve to reduce the Escrow Shares (and not the 11,008,789 shares of PRWT Common Stock to be issued pursuant to Section 1.6 that are not subject to the escrow described in Section 1.10), and that any such reduction shall be limited to the number of Escrow Shares actually remaining in the Escrow Account.

(j) The calculation of the Estimated Net Debt Amount and the Closing Net Debt Amount shall be made in accordance with U.S. GAAP (as defined in Section 2.7(a)) and consistent with past practice.

(k) If the Committee disagrees with the Closing Net Debt Statement used to calculate the Closing Net Debt Amount, it shall notify the Representative of such disagreement in writing specifying in reasonable detail any and all items of disagreement (each, an “Item of Dispute”) within fifteen (15) calendar days after its receipt of the Closing Net Debt Statement. The Representative and the Committee shall use their commercially reasonable best efforts for a period of fifteen (15) calendar days after the Committee’s delivery of such notice (or such longer period as PRWT and the Committee may mutually agree upon) to resolve any Items of Dispute raised by the Committee with respect to the Closing Net Debt Statement. During any such period of dispute, the Committee and Representative shall have reasonable access to the working papers of the Representative’s accountants relating to the Closing Net Debt Amount. If, at the end of such period, the Representative and the Committee do not resolve any such Item of Dispute, either the Representative or the Committee may submit the matter to a mutually acceptable independent accounting firm of recognized national standing to review the Closing Net Debt Statement and resolve any remaining Items of Dispute regarding the Closing Net Debt Amount. In the event the Representative and the Committee cannot agree upon an accounting firm within ten (10) days after notice from a party to the other party, they shall choose an accounting firm by lot from those accounting firms of recognized national standing practicing in Pennsylvania having no material relationship to the Representative, KBL, the Committee or their respective Affiliates and having offices in locations suitable to conduct such review. The accounting firm selected in accordance with the preceding two sentences is referred to herein as the “Accounting Firm.” The Representative and the Committee shall request that the Accounting Firm render a determination on each Item of Dispute, solely based on whether such Item of Dispute was prepared accurately and in accordance with U.S. GAAP and consistent with past practice. The determination by the Accounting Firm shall be final, binding and conclusive on the parties, and judgment may be entered thereon in a court of competent jurisdiction. The Representative and the Committee shall make their respective submissions to the Accounting Firm within twenty (20) business days after selecting such firm pursuant to this Section 1.7(i). The Representative and the Committee shall use their commercially reasonable best efforts to cause the Accounting Firm to make its determination within thirty (30) calendar days after accepting its selection. All of the fees and expenses of the Accounting Firm shall be borne by the Surviving Pubco.

(l) Required Withholding. The Surviving Pubco shall be entitled to deduct and withhold from any consideration payable or otherwise deliverable pursuant to this Agreement to any Person such amounts as are required to be deducted or withheld therefrom under the Code or under any provision of state, local or foreign tax law or under any other applicable legal requirement. 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.

1.8 Tax Consequences. It is intended by the parties hereto that the Merger shall constitute reorganization within the meaning of Section 368 of the Code. The parties hereto adopt this Agreement as a “plan of reorganization” within the meaning of Sections 1.368-2(g) and 1.368-3(a) of the United States Income Tax Regulations.

1.9 Taking of Necessary Action; Further Action. If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement and to vest the Surviving Pubco with full right, title and possession to all assets, property, rights, privileges, powers and franchises of PRWT and KBL, the then current officers and directors of KBL, and the officers and directors of PRWT shall take all such lawful and necessary action.

1.10 General Escrow. As the sole remedy for the indemnification obligations set forth in Article VII of this Agreement, and for downward adjustments to the Stockholder Shares required under Section 1.7, 941,211 of the Stockholder Shares (the “Escrow Shares”) shall be deposited in escrow (the “Escrow Account”), which shall be allocated among the Stockholders in the same proportion as the Stockholder Shares are allocated among them under Section 1.6, as set forth in Schedule 1.10, all in accordance with the terms and conditions of the escrow agreement to be entered into at the Closing between the Surviving Pubco, the Representative, each of the Stockholders (by power of attorney granted to the Representative appointed pursuant to Section 1.12(b)) and Continental, as escrow agent (“Escrow Agent”), in form and substance mutually and reasonably agreed to by KBL and PRWT and providing for the terms contemplated by Article VII hereof (the “Escrow Agreement”). The Escrow Agreement shall provide that, (i) on the 30th day after the date the Surviving Pubco has filed with the SEC its Annual Report for the year ending December 31, 2009 on Form 10-K (the “First Escrow Release Date”), the Escrow Agent shall release fifty percent (50%) of the Escrow Shares, less that portion thereof applied in satisfaction of or reserved with respect to indemnification claims in connection with claims made pursuant to Section 7.1(a) of this Agreement (“Escrow Claims”) and (ii) on the 30th day after the date the Surviving Pubco has filed with the SEC its Annual Report for the year ending December 31, 2010 on Form 10-K (the “Final Escrow Release Date”), the Escrow Agent shall release all Escrow Shares then remaining in escrow, less that portion thereof applied in satisfaction of or reserved with respect to Escrow Claims. Any Escrow Shares due to be released on the First Escrow Release Date or Final Escrow Release Date that continue to be held with respect to any unresolved Escrow Claim shall be delivered to the Stockholders in the same proportions as originally deposited into escrow, promptly upon such resolution, subject to reduction, if any, for the indemnification obligation associated with such resolved Escrow Claim.

1.11 EBITDA Share Issuance.

(a) At Closing, an additional 8,000,000 shares of PRWT Common Stock shall be issued by PRWT to the Stockholders in the same proportion as the Stockholder Shares are allocated among them under Section 1.6 (“EBITDA Shares”). All of the EBITDA Shares shall be deposited in escrow in accordance with the terms and conditions of the escrow agreement to be entered into at the Closing between the Surviving Pubco, the Representative, each of the Stockholders (by power of attorney granted to the Representative) in form and substance mutually and reasonably agreed to by PRWT and KBL and providing for the terms contemplated by this Section 1.11 (the “EBITDA Shares Escrow Agreement”). The EBITDA Shares Escrow Agreement shall provide that the Escrow Agent shall release the EBITDA Shares as follows:

(i) If the Surviving Pubco’s EBITDA (as defined in Section 1.11(c)) for the year ending December 31, 2009 (“2009 EBITDA”) is greater than $25,000,000, as set forth in the Surviving Pubco’s audited consolidated financial statements for the year ending December 31, 2009, the Stockholders, as a group, shall be entitled to receive from escrow that number of EBITDA Shares determined by dividing the 2009 EBITDA Excess by $1.00. “2009 EBITDA Excess” shall mean the Surviving Pubco’s actual 2009 EBITDA less $25,000,000. As an example, if the Surviving Pubco’s 2009 EBITDA is $27,000,000, the 2009 EBITDA Excess will be $2,000,000 and the Stockholders will receive from escrow an aggregate of 2,000,000 EBITDA Shares. Notwithstanding the foregoing, the maximum number of EBITDA Shares to be released from escrow pursuant to this Section 1.11(a)(i) shall be 2,000,000 shares.

(ii) If the Surviving Pubco’s EBITDA for the year ending December 31, 2010 (“2010 EBITDA”) is greater than $30,000,000 as set forth in the Surviving Pubco’s audited consolidated financial statements for the year ending December 31, 2010, the Stockholders, as a group, shall be entitled to receive from escrow that number of shares of PRWT Common Stock determined by dividing the 2010 EBITDA Excess by $1.00. “2010 EBITDA Excess” shall mean the Surviving Pubco’s actual 2010 EBITDA less $30,000,000. As an example, if the Surviving Pubco’s 2010 EBITDA is $32,000,000, the 2010 EBITDA Excess will be $2,000,000 and the Stockholders will receive from escrow an aggregate of 2,000,000 shares of PRWT Common Stock. Notwithstanding the foregoing, the maximum number of EBITDA Shares issuable under this Section 1.11(a)(ii) shall be 3,000,000 shares.

(iii) If the Surviving Pubco’s EBITDA for the year ending December 31, 2011 (“2011 EBITDA”) is greater than $40,000,000 as set forth in the Surviving Pubco’s audited consolidated financial statements for the year ending December 31, 2011, the Stockholders, as a group, shall be entitled to receive from escrow that number of shares of PRWT Common Stock determined by dividing the 2011 EBITDA Excess by $1.00. “2011 EBITDA Excess” shall mean the Surviving Pubco’s actual 2011 EBITDA less $40,000,000. As an example, if the Surviving Pubco’s 2011 EBITDA is $42,500,000, the 2011 EBITDA Excess will be $2,500,000 and the Stockholders will receive from escrow an aggregate of 2,500,000 shares of PRWT Common Stock. Notwithstanding the foregoing, the maximum number of EBITDA Shares issuable under this Section 1.11(a)(iii) shall be 3,000,000 shares.

(iv) In the event Surviving Pubco engages in (1) a merger or business combination in which it is not the survivor, (2) a transaction in which it sells all or substantially all of its assets, or (3) a similar liquidity event, which in any case results in all of the holders of PRWT Common Stock receiving consideration having a fair market value of $9.50 or more per share (as adjusted for and to equitably and appropriately reflect the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into PRWT Common Stock), extraordinary cash dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to PRWT Common Stock) then all EBITDA Shares then held in escrow in accordance with this Section 1.11 shall be released to the Stockholders no later than the consummation of such transaction. Further, in each event of exercise of PRWT Warrants (other than any exercise that occurs upon PRWT electing to lower the exercise price from the exercise price as of the date hereof, as same may be adjusted in connection with any stock split or the aforementioned similar events), an amount of EBITDA Shares equal to the number of shares of PRWT Common Stock issued upon such warrant exercise (up to the total amount of EBITDA Shares then held in escrow) shall be released from escrow and delivered to the Stockholders, in the same proportion as the Stockholder Shares are allocated among them under Section 1.6.

(b) Any release of EBITDA Shares from escrow shall be made as soon as practicable and in any event, no later than twenty (20) business days after the date of the event giving rise to the obligation to release such EBITDA Shares. A party’s right to receive the EBITDA Shares from escrow shall not be subject to any right of set-off or recoupment. The parties hereto acknowledge that the issuance of the EBITDA Shares is being done without any further consideration paid by the Stockholders, in order to provide a purchase price adjustment with respect to the PRWT Common Stock issued in the Merger by adjusting the percentage of equity issued in the Merger. Notwithstanding anything to the contrary herein, if, at anytime, following release of Surviving Pubco’s audited consolidated financial statement for the year ending December 31, 2009, no PRWT Warrants remain outstanding, any EBITDA Shares contemplated by Section 1.10(b)(i) that were not released to the Stockholders in accordance with such Section 1.10(b)(i) shall be immediately released from escrow and returned to Surviving Pubco for cancellation. Similarly, notwithstanding anything to the contrary herein, if, at anytime, following release of Surviving Pubco’s audited consolidated financial statement for the year ending December 31, 2010, no PRWT Warrants remain outstanding, any EBITDA Shares contemplated by Section 1.10(b)(ii) that were not released to the Stockholders in accordance with such Section 1.10(b)(ii) shall be immediately released from escrow and returned to Surviving Pubco for cancellation. After the date of release of any EBITDA Shares under Section 1.11(a)(iii) (following the release of Surviving Pubco’s audited consolidated financial statements for the year ending December 31, 2011), above, any and all EBITDA Shares then remaining in escrow shall be released from escrow and returned to the Surviving Pubco for cancellation.

(c) “EBITDA” for purposes hereof shall consist of the Surviving Pubco’s consolidated operating earnings before interest expense, depreciation and amortization expense, taxes on income, costs and expenses (including without limitation, legal and accounting) or write-downs directly related to the Merger or subsequent acquisition or other business combinations by the Surviving Pubco (except as provided below), foreign exchange gains and losses and extraordinary items of the Surviving Pubco. The term “EBITDA” shall include all EBITDA generated by the Surviving Pubco or any subsidiary thereof from any businesses or assets acquired by any of them after the Effective Time. Notwithstanding anything to the contrary herein, EBITDA calculations for purposes of this Agreement shall give effect to an imputed capital charge equal to 12.5% of the aggregate consideration paid by any of the Surviving Pubco, Subsidiaries thereof or their Affiliates in connection with each such acquisition or business combination (but shall not give effect to any other closing costs or upfront, one-time write-offs related to such acquisitions). EBITDA calculations also shall give effect to costs incurred or related to regulatory compliance; provided however that any costs or expenses incurred by the Surviving Pubco or any subsidiary thereof in initially implementing and establishing compliance with the Xxxxxxxx-Xxxxx Act of 2002 or other similar rules and regulations shall be specifically excluded from the calculation of EBITDA. EBITDA calculations shall not include any income from debt forgiveness or cancellation. Notwithstanding anything herein, the income of USF shall be included in the EBITDA calculation contemplated hereby.

1.12 Committee and Representative for Purposes of Escrow Agreements.

(a) KBL Committee. Prior to the Closing, the Board of Directors of KBL shall appoint a committee consisting of one or more of its then members to act on behalf of he Surviving Pubco to take all necessary actions and make all decisions pursuant to the Escrow Agreement and EBITDA Shares Escrow Agreement. In the event of a vacancy in such committee, the board of directors of KBL or, after the consummation of the Merger, the members of the board of directors of the Surviving Pubco, shall appoint as a successor a Person who was a director of KBL prior to the Closing Date or some other Person who would qualify as an “independent” director of the Surviving Pubco and who has not had any relationship with PRWT or the Stockholders prior to the Closing. Such committee is intended to be the “Committee” referred to in Article VII hereof and the Escrow Agreement and EBITDA Shares Escrow Agreement.

(b) Representative. Each Stockholder, by virtue of his, her or its execution of this Agreement, hereby makes, constitutes and appoints Xxxxxx X. Xxxxxxx (the “Representative”), with full power of substitution and re-substitution, as his, her or its true and lawful attorney-in-fact to execute and deliver each of the Escrow Agreement and EBITDA Shares Escrow Agreement on behalf of the Stockholders (and to execute and deliver all other documentation required thereby) and to represent the interests of the Persons entitled to receive Stockholder Shares and EBITDA Shares as a result of the transactions contemplated hereby for purposes of this Agreement, the Escrow Agreement and EBITDA Shares Escrow Agreement. The Representative shall be the exclusive agent for and on behalf of the Stockholders to: (i) give and receive notices and communications to or from KBL and/or the respective escrow agents under the Escrow Agreement and the EBITDA Shares Escrow Agreement relating to this Agreement, the Escrow Agreement, the EBITDA Shares Escrow Agreement or any of the transactions and other matters contemplated hereby or thereby; (ii) authorize deliveries to KBL and/or the Surviving Pubco of Escrow Shares from the escrow fund in satisfaction of claims asserted by KBL and/or the Surviving Pubco (on behalf of itself or any other KBL Indemnitee, including by not objecting to such claims); (iii) object to such claims; (iv) consent or agree to, negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to, such claims; (v) waive any condition in this Agreement, the Escrow Agreement or the EBITDA Shares Escrow Agreement on behalf of the Stockholders and (vi) take all actions necessary or appropriate in the judgment of the Representative for the accomplishment of the foregoing, in each case without having to seek or obtain the consent of any person under any circumstance. Notwithstanding the foregoing, the Representative shall not consent or agree to or negotiate or enter into any settlement and compromise of any claim that includes any admission of guilt, criminal liability or wrong-doing by any Stockholder unless approved in writing in advance by such Stockholder. The Representative shall be the sole and exclusive means of asserting or addressing any of the above and no Stockholder shall have any right to act on its own behalf with respect to any such matters or other matters relating to this Agreement or the transactions contemplated hereby, other than any claim or dispute against the Representative. If the Person serving as the Representative ceases to serve in such capacity, for any reason, those members of the board of directors of the Surviving Pubco who were members of the board of directors of PRWT prior to the Closing shall appoint as successor a Person who was a former director or PRWT or such other Person as such members shall designate. Such Person or successor is intended to be the “Representative” referred to in Article VII hereof, the Escrow Agreement and EBITDA Shares Escrow Agreement. KBL, the Surviving Pubco and each of their respective Affiliates shall be entitled to rely upon, and shall be fully protected in relying upon, the power and authority of the Representative without independent investigation. No bond shall be required of the Representative. The Representative shall receive no fees for his services but shall be entitled to reimbursement for his reasonable out-of-pocket expenses as provided below and in the Escrow Agreement and EBITDA Shares Escrow Agreement. Notices or communications to or from the Representative shall constitute notice to or from each of the Stockholders. KBL, the Surviving Pubco and each of their respective Affiliates shall have no liability to any of the Stockholders or any other constituencies for any acts or omissions of the Representative (including any failure to deliver amounts or shares paid to the Representative on behalf of any of the Stockholders or any other constituencies), or any acts or omissions taken or not taken by any other persons at the direction of the Representative. Any notice or communication given or received by, and any decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, the Representative that is within the scope of the Representative's authority under this Section 1.12(b) shall constitute a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of all Stockholders and shall be final, binding and conclusive upon each such Stockholder and the escrow agents under the Escrow Agreement and the EBITDA Shares Escrow Agreement and KBL and the Surviving Pubco shall be entitled to rely upon any such notice, communication, decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction as being a notice or communication to or by, or a decision, action, failure to act within a designated period of time, agreement, consent, settlement, resolution or instruction of, each and every such Stockholder. The Stockholders, jointly and severally, shall indemnify and hold harmless the Representative against any Losses (as defined in Section 7.1(b)) arising out of actions taken or omitted to be taken in his capacity as the Representative (except in the case of gross negligence or willful misconduct by the Representative), including the reasonable costs and expenses of investigation and defense of claims. The Representative shall not be liable to any of Stockholders or any of their respective Affiliates for any decisions made or actions taken by the Representative in good faith and believed by him to be authorized by, or within the rights or powers conferred upon him by, this Agreement, and may consult with counsel of his own choice.

(a) Notwithstanding Section 1.5 hereof, Dissenting Shares (as defined in Section 1.15(b)) shall not be converted into a right to receive PRWT Common Stock. The holders thereof shall be entitled only to such rights as are granted by the DGCL. Each holder of Dissenting Shares who becomes entitled to payment for such shares pursuant to the DGCL shall receive payment therefor from the Surviving Pubco in accordance with the DGCL, provided, however, that (i) if any stockholder of KBL who asserts appraisal rights in connection with the Merger (a “Dissenter”) shall have failed to establish his entitlement to such rights as provided in the DGCL, or (ii) if any such Dissenter shall have effectively withdrawn his demand for payment for such shares or waived or lost his right to payment for his shares under the appraisal rights process under the DGCL, the shares of KBL Common Stock held by such Dissenter shall be treated as if they had been converted, as of the Effective Time, into a right to receive PRWT Common Stock as provided in Section 1.5. KBL shall give PRWT prompt notice of any demands for payment received by KBL from a person asserting appraisal rights, and PRWT shall have the right to participate in all negotiations and proceedings with respect to such demands.

1.16 Outstanding PRWT Derivative Securities. All outstanding options to purchase Company Stock set forth on Schedule 2.3 shall remain outstanding at the Effective Time, but each such option shall represent the options under the Pubco Plan (as defined) to purchase approximately that number of shares of PRWT Common Stock set forth on Schedule 2.3 at the exercise prices set forth on Schedule 2.3.

1.17 Release Payment. In connection with the transactions contemplated hereby and upon the Closing, PRWT shall pay an aggregate of $3.5 million (the “Release Payment”) to the Stockholders, pro rata in accordance with their respective ownership of PRWT Common Stock existing prior to Closing, as set forth on Schedule 1.17. Such payment shall be in consideration of the release set forth in Section 1.14(a).

Each jurisdiction in which PRWT is so qualified or licensed is listed in Schedule 2.1.

ARTICLE VII

INDEMNIFICATION

7.1 Indemnification of KBL and Surviving Pubco.

(a) Subject to the terms and conditions of this Article VII (including without limitation the limitations set forth in Section 7.4), KBL, the Surviving Pubco and their respective representatives, successors and permitted assigns (the “KBL Indemnitees”) shall be indemnified, defended and held harmless with respect to the matters under Sections 7.1(a)(i) and 7.1(a)(ii), below, but only to the extent of the Escrow Shares, from and against all Losses asserted against, resulting to, imposed upon, or incurred by any KBL Indemnitee by reason of, arising out of or resulting from:

(i) the inaccuracy or breach of any representation or warranty of PRWT or any of the Stockholders contained in or made pursuant to this Agreement, any Schedule or any certificate delivered by PRWT to KBL pursuant to this Agreement with respect hereto or thereto in connection with the Closing;

(ii) the non-fulfillment or breach of any covenant or agreement of PRWT or any of the Stockholders contained in this Agreement;

(iii) the matter set forth in Schedule 2.15 of the PRWT Schedule relating to the payment of social security Taxes for the year 2006; and

(iv) the matters set forth in Schedule 2.16 of the PRWT Schedule.

(b) As used in this Article VII, the term “Losses”, subject to Section 7.4(e) hereof, shall include all actual losses, liabilities, damages, judgments, awards, orders, penalties, settlements, costs and expenses (including, without limitation, interest, penalties, court costs and reasonable legal fees and expenses) including those arising from any demands, claims, suits, actions, costs of investigation, notices of violation or noncompliance, causes of action, proceedings and assessments whether or not made by third parties or whether or not ultimately determined to be valid. Solely for the purpose of determining the amount of any Losses (and not for determining any breach) for which the KBL Indemnitees may be entitled to indemnification pursuant to Article VII, any representation or warranty contained in this Agreement that is qualified by a term or terms such as “material,” “materially,” or “Material Adverse Effect” shall be deemed made or given without such qualification and without giving effect to such words.

7.2 Indemnification of Third Party Claims. The indemnification obligations and liabilities under this Article VII with respect to actions, proceedings, lawsuits, investigations, demands or other claims brought against a KBL Indemnitee by a Person other than PRWT or a Stockholder (a “Third Party Claim”) shall be subject to the following terms and conditions:

(a) Notice of Claim. KBL or Surviving Pubco, acting through the Committee, will give the Representative prompt written notice after receiving written notice of any Third Party Claim or discovering the liability, obligation or facts giving rise to such Third Party Claim (a “Notice of Claim”) which Notice of Third Party Claim shall set forth (i) a brief description of the nature of the Third Party Claim, (ii) the total amount of the actual out-of-pocket Loss or the anticipated potential Loss (including any costs or expenses which have been or may be reasonably incurred in connection therewith), and (iii) whether such Loss may be covered (in whole or in part) under any insurance and the estimated amount of such Loss which may be covered under such insurance, and the Representative shall be entitled to participate in the defense of Third Party Claim at its expense.

(b) Defense. The Representative shall have the right, at its option (subject to the limitations set forth in subsection 7.2(c) below) and at its own expense, by written notice to KBL, to assume the entire control of, subject to the right of KBL to participate (at its expense and with counsel of its choice) in, the defense, compromise or settlement of the Third Party Claim as to which such Notice of Claim has been given, and shall be entitled to appoint a recognized and reputable counsel reasonably acceptable to KBL to be the lead counsel in connection with such defense. If the Representative is permitted and elects to assume the defense of a Third Party Claim:

(i) the Representative shall diligently and in good faith defend such Third Party Claim and shall keep the Committee reasonably informed of the status of such defense; provided, however, that the Committee shall have the right to approve any settlement, which approval will not be unreasonably withheld, delayed or conditioned except to the extent the settlement relates solely to monetary damages that are indemnified fully under Section 7.1; and

(ii) KBL, Surviving Pubco and the Committee shall cooperate fully in all respects with the Representative in any such defense, compromise or settlement thereof, including, without limitation, the selection of counsel, and KBL, Surviving Pubco and the Committee shall make available to the Representative all pertinent information and documents under its control.

(c) Limitations of Right to Assume Defense. The Representative shall not be entitled to assume control of such defense and, subject to the limitations of Section 7.4, shall pay the reasonable fees and expenses of one counsel retained by Surviving Pubco or the Committee if (i) the Third Party Claim relates to or arises in connection with any criminal proceeding, action, indictment, allegation or investigation; (ii) the Third Party Claim seeks an injunction or equitable relief against a KBL Indemnitee; or (iii) there is a reasonable probability that a Third Party Claim may materially and adversely affect Surviving Pubco or its Subsidiaries other than as a result of money damages or other money payments.

(d) Other Limitations. Failure to give prompt Notice of Claim or to provide copies of relevant available documents or to furnish relevant available data shall not constitute a defense (in whole or in part) to any Third Party Claim by a KBL Indemnitee against the Representative and shall not affect the Representative’s duty or obligations under this Article VII, except to the extent (and only to the extent that) such failure shall have adversely affected the ability of the Representative to defend against or reduce its liability or caused or increased such liability or otherwise caused the damages for which the Representative is obligated to be greater than such damages would have been had the Committee given the Representative prompt notice hereunder. So long as the Representative is defending any such action actively and in good faith, Surviving Pubco shall not settle such action. KBL and Surviving Pubco shall make available to the Representative all relevant records and other relevant materials required by them and in the possession or under the control of KBL or Surviving Pubco, for the use of the Representative and its representatives in defending any such action, and shall in other respects give reasonable cooperation in such defense.

(e) Failure to Defend. If the Representative, promptly after receiving a Notice of Claim, fails to defend such Third Party Claim actively and in good faith, Surviving Pubco or the Committee, subject to the limitations of Section 7.4, will (upon further written notice) have the right to undertake the defense, compromise or settlement of such Third Party Claim as it may determine in its reasonable discretion, provided that the Representative shall have the right to approve any settlement, which approval will not be unreasonably withheld, delayed or conditioned.

(f) KBL Indemnitee Rights. Anything in this Section 7.2 to the contrary notwithstanding, the Representative shall not, without the written consent of the Committee, settle or compromise any action or consent to the entry of any judgment which does not include as an unconditional term thereof the giving by the claimant or the plaintiff to each of the KBL Indemnitees of a full and unconditional release from all liability and obligation in respect of such action without any payment by any KBL Indemnitee.

(g) Representative Consent. Unless the Representative has consented to a settlement of a Third Party Claim, the amount of the settlement shall not be a binding determination of the amount of the Loss and such amount shall be determined in accordance with the provisions of the Escrow Agreement.

7.3 Insurance and Tax Effect.

(a) To the extent that any Losses that are subject to indemnification pursuant to this Article VII are covered by insurance, Surviving Pubco shall use reasonable best efforts to obtain the maximum recovery under such insurance; provided that KBL Indemnitees shall nevertheless be entitled to bring a claim for indemnification under this Article VII in respect of such Losses and the time limitations set forth in Section 7.4 hereof for bringing a claim of indemnification under this Agreement shall be tolled during the pendency of such insurance claim. The existence of a claim by KBL or Surviving Pubco for monies from an insurer or against a third party in respect of any Loss shall not, however, delay any payment pursuant to the indemnification provisions contained herein and otherwise determined to be due and owing by the Representative. If KBL or Surviving Pubco has received the payment required by this Agreement from the Representative in respect of any Loss and later receives proceeds from insurance or other amounts in respect of such Loss, then it shall hold such proceeds or other amounts in trust for the benefit of the Representative and shall pay to the Representative, as promptly as practicable after receipt, a sum equal to the amount of such proceeds or other amount received, up to the aggregate amount of any payments received from the Representative pursuant to this Agreement in respect of such Loss. Notwithstanding any other provisions of this Agreement, it is the intention of the parties that no insurer or any other third party shall be (i) entitled to a benefit it would not be entitled to receive in the absence of the foregoing indemnification provisions, or (ii) relieved of the responsibility to pay any claims for which it is obligated.

(b) To the extent that any Losses that are subject to indemnification pursuant to this Article VII are deductible for income tax purposes by KBL, PRWT, the Merger Sub or the Surviving Pubco, as the case may be, the amount of any Loss shall be reduced by the income tax savings to such party as a result of the payment of such Loss.

7.4 Limitations on Indemnification.

(a) Survival; Time Limitation. The representations, warranties, covenants and agreements in this Agreement or in any writing delivered by PRWT, the Stockholder or Merger Sub to KBL in connection with this Agreement (including the certificate required to be delivered by PRWT pursuant to Section 6.3(a)) shall survive the Closing until the Final Escrow Release Date (the “Survival Period”).

(b) Any indemnification claim made by KBL or Surviving Pubco in writing prior to the termination of the Survival Period shall be preserved despite the subsequent termination of the Survival Period and any claim set forth in a Notice of Claim sent prior to the expiration of such Survival Period shall survive until final resolution thereof. Except as set forth in the immediately preceding sentence, (i) no claim for indemnification under this Article VII shall be brought after the end of the Survival Period, and (ii) the indemnification rights of KBL Indemnitees under this Article VII shall terminate and be of no further force or effect.

(c) Deductible. No amount shall be payable under Article VII unless and until the aggregate amount of all indemnifiable Losses otherwise payable exceeds $1,000,000 (the “Deductible”), in which event the amount payable shall be only the amount in excess of the Deductible.

(d) Aggregate Amount Limitation. The aggregate liability for Losses pursuant to Section 7.1 shall not in any event exceed the Escrow Shares and no KBL Indemnitee shall have any claim against PRWT’s stockholders other than the Escrow Shares during the Escrow Period.

(e) No Special or Consequential Damages. In no event shall Losses be deemed to include any special, indirect, consequential or punitive damages.

7.5 Exclusive Remedy. Except with respect to the return of EBITDA Shares to Surviving Pubco under Section 1.11 and with respect to the return of PRWT Common Stock under Section 1.7, each of KBL and Surviving Pubco on behalf of itself and the other KBL Indemnitees, hereby acknowledges and agrees that, from and after the Closing, the sole remedy of the KBL Indemnitees with respect to any and all claims for money damages arising out of or relating to this Agreement shall be pursuant and subject to the requirements of the indemnification provisions set forth in this Article VII. Notwithstanding any of the foregoing, nothing contained in this Article VII shall in any way impair, modify or otherwise limit a KBL Indemnitees’ right to bring any claim, demand or suit against the other party based upon such other party’s actual fraud.

7.6 Adjustment to Purchase Price. Amounts paid for indemnification under Article VII shall be deemed to be an adjustment to the “purchase price” paid to the Stockholders in connection with business combination between PRWT and KBL, except as otherwise required by Law.

7.7 Representative Capacities; Application of Escrow Shares. The parties acknowledge that the Representative’s obligations under this Article VII are solely as a representative of the Stockholders in the manner set forth in the Escrow Agreement with respect to the obligations to indemnify the KBL Indemnitees under this Article VII and that the Representative shall have no personal responsibility for any expenses incurred by him in such capacity and that all payments to the KBL Indemnitees as a result of such indemnification obligations shall be made solely from, and to the extent of, the Escrow Shares. Out-of-pocket expenses of the Representative for attorneys’ fees and other costs shall be borne in the first instance by KBL, which may make a claim for reimbursement thereof against the Escrow Shares upon the claim with respect to which such expenses are incurred becoming an Established Claim (as defined in the Escrow Agreement). The parties further acknowledge that all actions to be taken by the KBL Indemnitees pursuant to this Article VII shall be taken on their behalf by the Committee in accordance with the provisions of the Escrow Agreement. The Escrow Agent, pursuant to the Escrow Agreement after the Closing, may apply all or a portion of the Escrow Shares to satisfy any claim for indemnification pursuant to this Article VII. The Escrow Agent will hold the remaining portion of the Escrow Shares until final resolution of all claims for indemnification or disputes relating thereto. Notwithstanding anything to the contrary contained herein, all Escrow Shares remaining in escrow following the Final Escrow Release Date in excess of the Escrow Shares necessary to satisfy any timely filed claim for indemnification shall be released and delivered to the Persons entitled to them on such date. Notwithstanding anything to the contrary contained herein, the Representative shall have no liability to PRWT or any Stockholder or any party hereto for any action taken or omitted to be taken hereunder, unless such liability is determined by a judgment or a court of competent jurisdiction to have resulted from the gross negligence, or willful misconduct of the Representative. KBL shall defend, indemnify and hold harmless the Representative for all losses, damages, costs and expenses (including reasonable attorney’s fees and costs of investigation) arising out of or in connection with, the performance by the Representative of its duties and obligations under this Agreement, unless such liability is determined by a judgment or a court of competent jurisdiction to have resulted from the gross negligence, or willful misconduct of the Representative.

7.8 EBITDA Shares Escrow and Net Debt Adjustments. For clarity, no provision of this Article VII shall govern with respect to the EBITDA Shares, which shall be governed by the EBITDA Shares Escrow Agreement, or with respect to the return of shares to the Surviving Pubco as may be required under Section 1.7.

ARTICLE VIII

8.1 Termination. This Agreement may be terminated at any time prior to the Closing:

(a) by mutual written agreement of KBL and PRWT at any time;

(b) by either KBL or PRWT if the Merger shall not have been consummated by July 19, 2009; provided, however, that the right to terminate this Agreement under this Section 8.1(b) shall not be available to any party whose action or failure to act has been a principal cause of or resulted in the failure of the Merger to occur on or before such date and such action or failure to act constitutes a breach of this Agreement;

(c) by either KBL or PRWT if a Governmental Entity shall have issued an order, decree, judgment or ruling or taken any other action, in any case having the effect of permanently restraining, enjoining or otherwise prohibiting the Merger, which order, decree, ruling or other action is final and nonappealable;

(e) by KBL, upon a material breach of any representation, warranty, covenant or agreement on the part of PRWT or a Stockholder set forth in this Agreement, or if any representation or warranty of PRWT or a Stockholder shall have become untrue, in either case such that the conditions set forth in Article VI would not be satisfied as of the time of such breach or as of the time such representation or warranty shall have become untrue, provided, that if such breach is curable by PRWT prior to the Closing Date, then KBL may not terminate this Agreement under this Section 8.1(e) for thirty (30) days after delivery of written notice from KBL to PRWT of such breach, provided PRWT or such Stockholder continues to exercise commercially reasonable best efforts to cure such breach (it being understood that KBL may not terminate this Agreement pursuant to this Section 8.1(e) if it shall have materially breached this Agreement or if such breach by PRWT or such Stockholder is cured during such thirty (30)-day period);

(f) by either KBL or PRWT, if, at the Special Meeting (including any adjournments thereof), this Agreement and the transactions contemplated hereby shall fail to be approved and adopted by the affirmative vote of the holders of KBL Common Stock required under KBL’s certificate of incorporation, or the holders of 30% or more of the number of shares of KBL Common Stock issued in KBL’s initial public offering and outstanding as of the date of the record date of the Special Meeting exercise their rights to convert the shares of KBL Common Stock held by them into cash in accordance with KBL’s certificate of incorporation;

8.2 Notice of Termination; Effect of Termination.

8.3 Fees and Expenses. All fees and expenses incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such expenses whether or not the Merger is consummated.

8.5 KBL Damages. The parties acknowledge and agree that if PRWT or the Stockholders wrongfully fail or refuse to consummate the Merger or KBL terminates this Agreement pursuant to Section 8.1(e), KBL and its stockholders may incur significant damages, including damages resulting from KBL being required to dissolve and liquidate in accordance with the KBL Charter Documents, provided that nothing herein shall preclude the need for KBL or its stockholders to prove their actual damages resulting from such failure or refusal.

10.3 Counterparts; Electronic Delivery. This Agreement and each other document executed in connection with the transactions contemplated hereby, and the consummation thereof, may be executed in one or more counterparts, all of which shall be considered one and the same document and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party, it being understood that all parties need not sign the same counterpart. Delivery by facsimile or electronic transmission to counsel for the other party of a counterpart executed by a party shall be deemed to meet the requirements of the previous sentence.

10.4 Entire Agreement; Third Party Beneficiaries. This Agreement and the documents and instruments and other agreements among the parties hereto as contemplated by or referred to herein, including the Exhibits and Schedules hereto (a) constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and understandings, both written and oral, among the parties with respect to the subject matter hereof, it being understood that the letter of intent between KBL and PRWT executed on or about February 12, 2009 is hereby terminated in its entirety and shall be of no further force and effect (except to the extent expressly stated to survive the execution of this Agreement and the consummation of the transactions contemplated hereby); and (b) are not intended to confer upon any other person any rights or remedies hereunder (except as specifically provided in this Agreement).

10.5 Severability. In the event that any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto. The parties further agree to replace such void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the economic, business and other purposes of such void or unenforceable provision.

10.6 Other Remedies; Specific Performance. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity.

10.7 Governing Law. This Agreement shall be governed by and construed in accordance with the internal law of the State of Delaware regardless of the law that might otherwise govern under applicable principles of conflicts of law thereof.

10.8 Arbitration. Any disputes or claims arising under or in connection with this Agreement or the transactions contemplated hereunder shall be resolved by binding arbitration. Notice of a demand to arbitrate a dispute by either party shall be given in writing to the other at their last known address. Arbitration shall be commenced by the filing by a party of an arbitration demand with the American Arbitration Association (“AAA”). The arbitration and resolution of the dispute shall be resolved by a single arbitrator appointed by the AAA pursuant to AAA rules. The arbitration shall in all respects be governed and conducted by applicable AAA rules, and any award and/or decision shall be conclusive and binding on the parties. The arbitration shall be conducted in Wilmington, Delaware. The arbitrator shall supply a written opinion supporting any award, and judgment may be entered on the award in any court of competent jurisdiction. Each party shall pay its own fees and expenses for the arbitration, except that any costs and charges imposed by the AAA and any fees of the arbitrator for his services shall be assessed against the losing party by the arbitrator. In the event that preliminary or permanent injunctive relief is necessary or desirable in order to prevent a party from acting contrary to this Agreement or to prevent irreparable harm prior to a confirmation of an arbitration award, then either party is authorized and entitled to commence a lawsuit solely to obtain equitable relief against the other pending the completion of the arbitration in a court having jurisdiction over the parties. Each party hereby consents to the exclusive jurisdiction of the federal and state courts located in the State of Delaware, New Castle County, for such purpose.

10.9 Rules of Construction. The parties hereto agree that they have been represented by counsel during the negotiation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.

10.10 Assignment. No party may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other parties. Subject to the first sentence of this Section 10.10, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

10.11 Amendment. This Agreement may be amended by the parties hereto at any time by execution of an instrument in writing signed on behalf of each of the parties.

10.12 Extension; Waiver. At any time prior to the Closing, any party hereto may, to the extent legally allowed, (i) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (ii) waive any inaccuracies in the representations and warranties made to such party contained herein or in any document delivered pursuant hereto and (iii) waive compliance with any of the agreements or conditions for the benefit of such party contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. Delay in exercising any right under this Agreement shall not constitute a waiver of such right.

10.13 Currency. All references to currency amounts in this Agreement shall mean United States dollars.

10.14 Schedules. The information furnished in the Schedules is arranged in sections corresponding to the Sections of this Agreement, and the disclosures in any section of the Schedules shall qualify (a) the corresponding Section of this Agreement and (b) other Sections of this Agreement to the extent (notwithstanding the absence of a specific cross-reference), that it is clear from a reasonable reading of the Schedules and such other Sections of this Agreement that such disclosure is also applicable to such other Sections of this Agreement. The Schedules and the information and disclosures contained in such Schedules are intended only to qualify and limit the representations and warranties of the parties contained in this Agreement and shall not be deemed to expand in any way the scope of any such representation or warranty. The inclusion of any information in the Schedules shall not be deemed to be an admission or acknowledgment that such information is material or outside the ordinary course of business. The inclusion of any fact or information in a Schedule is not intended to be construed as an admission or concession as to the legal effect of any such fact or information in any proceeding between any party and any Person who is not a party.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed as of the date first written above.
