Within ninety (90) calendar days after the Closing Date, PI shall prepare and deliver to IPC-Canada an unaudited consolidated balance sheet of the Company as of the close of business on the Closing Date and immediately prior to the Closing (the “Closing Date Balance Sheet”). The Closing Date Balance Sheet shall (x) be expressed in Canadian Dollars (Cdn $); (y) be prepared in accordance with GAAP and incorporate all accounting methods which are in accordance with GAAP and were utilized by the Company in connection with the preparation of the balance sheet of the Company as at March 31, 2006, included as part of the Financial Statements; and (z) for avoidance of doubt and without duplication, reflect all accruals required by GAAP in respect of compensation, including,

as applicable, amounts in respect of salary, bonuses, sick pay, vacation pay, commissions, pension plan contributions and employee benefits. The Closing Date Balance Sheet shall also include a calculation of the Closing Date Working Capital.

(b) Notice of Dispute. In the event that IPC-Canada wishes to dispute PI’s preparation of the Closing Date Balance Sheet or its calculation of the Closing Date Working Capital, IPC-Canada shall, within ninety (90) calendar days after receipt of the Closing Date Balance Sheet, give written notice to PI of such dispute and the reasons therefor. PI and IPC-Canada shall attempt in good faith to resolve such dispute within fifteen (15) calendar days after receipt by PI of such notice of dispute, and in the event that the parties are unable to resolve such dispute within such period, the parties agree that the Toronto or other Canadian office of the accounting firm of Xxxxx Xxxxxxxx (or any other reputable independent certified public accounting firm that shall be mutually agreed upon by PI and IPC-Canada, in the exercise of their reasonable discretion) (the “Accounting Firm”) shall be employed to resolve such dispute as soon as reasonably practicable. Prior to engaging an accounting firm as the Accounting Firm, the parties shall request the proposed accounting firm to identify any matter for which such accounting firm (including its Affiliates) has been engaged by any of the parties and their respective Affiliates since December 31, 2003, as well as the general nature of such matter and the amount of fees received by such accounting firm in such matter, and each of the parties agrees to promptly provide the accounting firm with a list of their Affiliates for this purpose. If, pursuant to the preceding sentence, the proposed accounting firm identifies that a party or its Affiliates engaged the proposed accounting firm, then the party that did not so engage such accounting firm shall be entitled to reject the engagement of such accounting firm as the Accounting Firm to resolve a dispute pursuant to this Section 1.5, and, in such case, the parties shall select another accounting firm to be engaged as the Accounting Firm. This process shall be repeated until an accounting firm is engaged by the parties as the Accounting Firm.

(c) Determination of Accounting Firm. The parties shall direct the Accounting Firm to review the books and records of the Company as necessary in order to verify the accuracy of the Closing Date Balance Sheet and to calculate the Closing Date Working Capital. The determination of such Accounting Firm shall be final and binding upon the parties. In the event that the Accounting Firm is so employed, the fees and costs charged by the Accounting Firm shall be borne by PI and IPC-Canada equally.

(d) Adjustment.

(i) If the Closing Date Working Capital is less than Target Working Capital by an amount exceeding Cdn $150,000 (the amount of such excess being herein referred to as the “Working Capital Shortfall”, the PPSS Shares Purchase Price shall be decreased by the amount equal to the Working Capital Shortfall, and PI shall pay to IPC-Canada an amount, payable in Canadian Dollars (Cdn $), equal to the Working Capital Shortfall. At the option of IPC-Canada the Working Capital Shortfall shall be payable in US Dollars (US $) and, in such case, the Working Capital Shortfall shall be converted from Canadian Dollars (Cdn $) to US Dollars (US $) at the noon exchange rate announced by the New York Federal Reserve Bank on the date that the Closing Date Working Capital is finally determined, whether by the mutual agreement of PI and IPC-Canada or by determination of the Accounting Firm; provided, however, that in order to

exercise this option, IPC-Canada shall deliver appropriate written notice to PI within two business days after the dates that the Closing Date Working Capital is finally determined.

(ii) If the Closing Date Working Capital is greater than the Target Working Capital by an amount exceeding Cdn $150,000 (the amount of such excess being herein referred to as the “Working Capital Surplus”), the PPSS Shares Purchase Price shall be increased by the amount of the Working Capital Surplus, and IPC-Canada shall pay to PI an amount, payable in Canadian Dollars (Cdn $), equal to the Working Capital Surplus.

(iii) Payment of the Working Capital Surplus or the Working Capital Shortfall, as applicable, shall be made within 5 calendar days after the final determination of the Closing Date Working Capital, whether by the mutual agreement of PI and IPC-Canada or by determination of the Accounting Firm.

At the Closing, upon delivery of and payment for the PPSS Georgia Shares as provided in this Agreement, all of the PPSS Georgia Shares shall be transferred to IPC-US, and IPC-US shall have good and valid title to the PPSS Georgia Shares free and clear of any Liens, other than Permitted Liens.

ARTICLE VIII
ADDITIONAL COVENANTS

8.1 Confidentiality. Whether or not the transactions contemplated hereby are consummated, Purchasers, PPSS and PI shall keep confidential all (a) confidential information relating to the marketing strategies, pricing policies or characteristics, customers, suppliers and customer and supplier information, customer and supplier lists, product or product specifications, Proprietary Rights, designs, manufacturing, testing or assembly processes or costs, costs of materials, business or business prospects, plans, proposals, codes, marketing studies, research, reports, investigations, or other information of similar character which relate to the Business or the Company, and (b) information and materials regarding another party reasonably designated by such party as confidential at the time of disclosure thereof (collectively referred to as“Confidential Information”). If the transactions contemplated hereby are consummated, PI shall maintain confidential and shall not use or disclose, directly or indirectly (except as required by law or as authorized in writing by Purchasers prior to such disclosure), any Confidential Information including all Confidential Information relating to the Company or the Business. If the transactions contemplated hereby are not consummated, Purchasers will return to Sellers all Confidential Information (in whatever medium or embodiment) which has been provided to Purchasers pursuant to this Agreement or otherwise in connection with this transaction, and Purchasers will destroy all copies of any analyses, compilations, studies or other documents

prepared by Purchasers or for Purchasers’ use containing or reflecting any such Confidential Information. For the avoidance of doubt, the Nondisclosure Agreement shall survive termination of this Agreement.

8.2 Restrictive Covenants.

(a) Non-interference with Customer and Supplier Relationships. Except for such actions as are necessary to ensure the compliance by PI of its obligations under this Agreement and the Ancillary Documents, PI covenants and agrees that neither PI nor any Subsidiary or Affiliate of PI, including Xxxxxxxx Xxxxxx, shall, for a period of five years following the date hereof, directly or indirectly, on its own behalf or on behalf of any other Person, contact or do business with any customer or supplier of the Business with respect to any product or service which is competitive with any product or service which constitutes, or is part of, the Business as of the date hereof. This covenant applies to those customers and suppliers, and their respective Affiliates to which the Company or any of its Affiliates have sold their products or services as part of the Business prior to the date hereof, and those prospective customers and suppliers with which the Company or any of its Affiliates have actively pursued sales or supply opportunities prior to the date hereof.

(b) Non-Competition. Except for such actions as are necessary to ensure the compliance by PI of its obligations hereunder and under the Ancillary Documents, PI covenants and agrees that neither PI, nor any Subsidiary or Affiliate of PI, including Xxxxxxxx Xxxxxx shall, for a period of five years following the date hereof, directly or indirectly own an interest in, operate, join, control, advise, work for, consult to, have a financial interest which provides any control of, or participate in any Person producing, designing, providing, soliciting orders for, selling, distributing, consulting to, or marketing or re-marketing products or services competitive with or in substantially the same line of business as the Business, or any part thereof, as of the date hereof. This prohibition applies in Canada and the United States. This covenant does not prohibit the mere ownership of less than 5% of the outstanding stock of any publicly-traded corporation as long as PI is not otherwise in violation of this Agreement. Nothing contained in this Section 8.2 shall limit PI or any of its Subsidiaries or Affiliates from continuing to conduct the Existing PI Businesses.

(c) Non-Recruitment. PI agrees that Purchasers have invested and will invest substantial time and effort in acquiring and maintaining its workforce. Accordingly, PI agrees that for a period of five years following the date hereof, neither PI nor any Subsidiary or Affiliate of PI, including Xxxxxxxx Xxxxxx shall hire away, or cause any other Person to hire away, (i) any employee of the Company as of the date hereof or (ii) any employee of either Purchaser, nor, in either case, directly or indirectly entice or solicit or seek to induce or influence any of such employees to leave their employment.

(d) Remedies. PI acknowledges and agrees that the Restrictive Covenants are an essential and material term of this Agreement and without such provisions, Purchasers would not have agreed to purchase the PPSS Georgia Shares or the PPSS Shares or entered into this Agreement. PI acknowledges that should it violate any of the covenants contained in this Section 8.2 (collectively, the“Restrictive Covenants”), it will be difficult to determine the resulting damages to Purchasers and their Affiliates and, in addition to any other remedies

Purchasers and their Affiliates may have, Purchasers and their Affiliates shall be entitled to temporary injunctive relief without being required to post a bond and permanent injunctive relief without the necessity of proving actual damage. The Purchasers may elect to seek such remedy at their sole discretion on a case by case basis. Failure to seek any or all remedies in one case shall not restrict Purchasers from seeking any remedies in another situation. Such action by Purchasers shall not constitute a waiver of any of their rights.

(e) Severability and Modification of Any Unenforceable Covenant. It is the parties’ intent that each of the Restrictive Covenants be read and interpreted with every reasonable inference given to its enforceability. However, it is also the parties’ intent that if any term, provision or condition of the Restrictive Covenants is held by a court of competent jurisdiction to be invalid, void or unenforceable, the remainder of the provisions thereof shall remain in full force and effect and shall in no way be affected, impaired or invalidated. Finally, it is also the parties’ intent that if a court should determine any of the Restrictive Covenants are unenforceable because of over-breadth, then the court shall modify said covenant so as to make it reasonable and enforceable under the prevailing circumstances.

8.3 Tax Returns.

(a) Any Taxes for a tax period beginning before the Closing Date and ending after the Closing Date (a “Straddle Period”) shall be apportioned between PI and the Purchasers, in the case of real and personal property Taxes and franchise Taxes not based on gross or net income, on a per diem basis and, in the case of other Taxes (including sales or transfer Taxes), shall be determined based on an interim closing of the books as of the dose of business on the Closing Date. Notwithstanding the foregoing, in the case of any Tax based upon or measured by capital (including net worth or long-term debt) or intangibles, the amount of such Tax allocated to the portion of the tax period ending on the Closing Date shall be computed by reference to the level of such items on the Closing Date.

(b) PI, at its own expense, shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company for all periods ending on or prior to the Closing Date which are filed after the Closing Date. Without limiting the foregoing, with respect to such Tax Returns, PI shall have the right to utilize any available tax attributes of PPSS existing as of the end of the taxable period including the Closing Date in order to offset any taxable income to PPSS for the applicable period. PI shall permit Purchasers to review and approve each such Tax Return described in the preceding sentence prior to filing (which approval shall not be unreasonably withheld). Purchasers, at their own expense, shall prepare or cause to be prepared and file or cause to be filed any Tax Returns of the Company for any Straddle Period. Purchasers shall permit PI to review and approve each such Tax Return described in the preceding sentence prior to filing (which approval shall not be unreasonably withheld). Purchasers shall not allow the Company to file any amended Tax Return with respect to any Pre-Closing Tax Period without the prior approval of PI (which approval shall not be unreasonably withheld). All Tax Returns described in this Section 8.3(b) shall be prepared in a manner consistent with the past practice of the Company unless such past practice has been determined to be incorrect by the applicable Governmental Authority or a contrary treatment is required by applicable Tax Laws (or the judicial or administrative interpretations thereof).

Nothing in this Section 8.3(b) shall be interpreted to prevent the Company from timely filing any Tax Return when due.

(c) The provisions of Section 7.4 to the contrary notwithstanding, PI shall control all proceedings (including selection of counsel and accountants) taken in connection with any Tax Audit with respect to tax periods beginning on or prior to the Closing Date; provided, however, that PI shall provide Purchasers the opportunity to participate, as may reasonably be requested by Purchasers, with PI in contesting any Tax Audit to the extent such Tax Audit may adversely affect the Company in any Tax period (or portion thereof) beginning on or after the Closing Date. Notwithstanding the foregoing, neither PI nor the Purchasers shall settle or compromise, or shall permit the Company to settle or compromise, any Tax Audit without the other party’s prior consent (which consent shall not be unreasonably withheld or delayed). Each party’s participation in any Tax Audit shall be at its own expense. Each of the parties agrees to provide the other parties with a copy of any written communication received from any Governmental Authority relating to the taxation the Company within ten (10) calendar days of its receipt of such communication,

(d) After the Closing Date, as reasonably requested, PI and Purchasers shall cooperate with one another and shall furnish or cause to be furnished to one another, as promptly as practicable, such information and assistance (to the extent within the control of such party) relating to the filing of any Tax Returns, the making of any election related to Taxes, the preparation for any audit by any Taxing Authority, and the prosecution or defense of any claim, suit or proceeding related to any Tax Return.

(e) Eighty percent (80%) of any refunds or credits of Taxes, plus the after-tax amount of any interest received or credited with respect thereto, of the Company arising in or with respect to any Pre-Closing Tax Period (including refunds or credits arising by reason of amended Tax Returns filed after the Closing Date) shall be for the account of PI and shall be paid by Purchasers to PI as an increase in the purchase price of the relevant shares within ten business days after (i) Purchasers or any Affiliate receives such refund, or (ii) the relevant Tax Return is filed in which the credit is applied against any liability of the Company (or any successor) for Taxes for a period other than a Pre-Closing Tax Period. Notwithstanding the foregoing, (a) PI shall be entitled to the full amount of any refunds applied for prior to the Closing Date and received after the Closing Date, and (b) it is understood that Tax credits arising in or with respect to Pre-Closing Tax Periods may be credited and applied in full against the Tax liability of the Company for any Pre-Closing Tax Period and shall not be subject to the eighty percent (80%) limitation of the preceding sentence except to the extent the application of such credits results in a refund payable by Purchasers to PI pursuant to clause (i) of the preceding sentence. Purchasers agree that they shall not, and shall not allow their Affiliates to, take any action (including, for the avoidance of doubt, preparation of a Tax Return in a manner that fails to utilize available Tax credits on an earliest to expire basis) a principal purpose of which is to prevent the Company (or any successor) from utilizing any Tax credit for which PI is entitled to payment upon use by the Company (or successor) pursuant to this Section 8.3(e). In the event that Purchaser makes a payment to PI pursuant to this Section 8.3(e) and, subsequently, the refund or credit which gave rise to such payment is disallowed by the applicable Governmental Authority, PI shall promptly repay to Purchaser the amount of the payment previously received

by it in respect of such disallowed refund or credit plus any interest charged to the Company by the Governmental Authority with respect to such disallowance.

(f) IPC-Canada and PI shall each pay 50% of all transfer, stamp or similar Taxes, if any, payable in connection with the consummation of the transactions contemplated by this Agreement.

8.4 Public Announcements. No party will issue or cause the publication of, nor will PI permit the Company to issue, any press release or other public announcement with respect to this Agreement or the transactions contemplated hereby without the prior consent of the other parties hereto; provided, however, that nothing herein will prohibit a party from issuing or causing the publication of any such press release or public announcement to the extent that such party is advised by its legal counsel that such action is required by law, in which case the party making such determination will use reasonable efforts to allow the other parties reasonable time to comment on such release or announcement in advance of its issuance.

8.5 PI Releases. Effective on the Closing Date, PI, for itself and for its Affiliates, agents, servants and legal representatives, and their successors and assigns, fully and unconditionally waives, releases and forever discharges all claims, demands, causes of action, obligations, damages and liabilities of any nature whatsoever (any of the foregoing, individually, a “Claim ”), which it or its Affiliates, agents and their successors or assigns ever had, now have, or hereafter may have against the Company and its officers, directors, controlling persons (if any), Affiliates, employees, attorneys, agents and stockholders, (each, a “Company Releasee”) whether known or unknown, whether now existing or which may hereafter arise, which PI had, has or claims to have against them with respect to all matters that existed between PI, on the one hand, and any Company Releasee, on the other, prior to the Closing. Notwithstanding the foregoing, for the purpose of this Section 8.5, the term “Claim” shall exclude (i) claims and causes of action arising under this Agreement, each Ancillary Document and/or any other agreement, document or instrument executed and delivered at or in connection with the transactions contemplated hereby, including, without limitation, claims for indemnification under Article VII and claims to enforce the covenants contained herein, and (ii) monetary obligations owed by Purchasers or the Company to PI (or an Affiliate of PI other than the Company).

PI intends in granting each Company Releasee this release that it shall be effective as a bar to each and every Claim, and expressly consents that this release shall be given full force and effect according to its terms and provisions, including those relating to unknown and unsuspected Claims, if any, (notwithstanding any federal, state or local law that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), as well as those relating to any other Claims described or implied above. PI acknowledges and agrees that this waiver is an essential and material term of this Agreement and without such waiver, Purchasers would not have agreed to acquire the PPSS Georgia Shares or the PPSS Shares or entered into this Agreement. PI further agrees that in the event that PI brings any Claim in which PI seeks damages against any Company Releasee, or in the event PI seeks to recover against any Company Releasee in any Claim brought by a governmental agency on such PI’s behalf, this release shall serve as a complete defense to such Claims. PI understands and agrees that this Agreement and the transactions contemplated hereby are not in any way to be

interpreted as admissions by any Company Releasee that PI has any viable Claims against any Company Releasee.

8.6 Company Releases. Effective on the Closing Date, Purchasers, on behalf of the Company, the Company’s agents, servants and legal representatives, and their successors and assigns, fully and unconditionally waives, releases and forever discharges all Claims which it and its agents and their successors or assigns ever had, now have, or hereafter may have against PI and its officers, directors, controlling persons (if any), Affiliates, employees, attorneys, agents and stockholders, (each, a “PI Releasee”) whether known or unknown, whether now existing or which may hereafter arise, which the Company had, has or claims to have against them with respect to all matters that existed between PI, on the one hand, and any PI Releasee, on the other, including the fiduciary duty any PI Releasee may have owed the Company by virtue of its capacity as a shareholder, director, officer or employee of the Company, prior to the Closing. Notwithstanding the foregoing, for the purpose of this Section 8.4, the term “Claim” shall exclude (i) claims and causes of action arising under this Agreement, each Ancillary Document and/or any other agreement, document or instrument executed and delivered at or in connection with the transactions contemplated hereby, including, without limitation, claims for indemnification under Article VII and claims to enforce the covenants contained herein, and (ii) monetary obligations owed by PI (or an Affiliate of PI other than the Company) to the Company or Purchasers.

Purchasers intend in granting each PI Releasee this release that it shall be effective as a bar to each and every Claim of the Company, and expressly consent that this release shall be given full force and effect according to its terms and provisions, including those relating to unknown and unsuspected Claims, if any, (notwithstanding any federal, state or local law that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), as well as those relating to any other Claims described or implied above. Purchasers acknowledge and agree that this waiver is an essential and material term of this Agreement and without such waiver, PI would not have agreed to sell the PPSS Shares or permitted PPSS to sell the PPSS Georgia Shares or entered into this Agreement. Purchasers further agree that in the event that any Purchaser or the Company brings any Claim in which it seeks damages against any PI Releasee or in the event Purchasers or the Company seeks to recover against any PI Releasee in any Claim brought by a governmental agency on Purchasers’ or the Company’s behalf, this release shall serve as a complete defense to such Claims. Purchasers understand and agree that this Agreement and the transactions contemplated hereby are not in any way to be interpreted as admissions by any PI Releasee that the Company has any viable Claims against any PI Releasee.

8.7 COBRA. Notwithstanding any provision of this Agreement to the contrary, following the Closing, the Company shall provide those “qualifying beneficiaries” who terminate their employment with the Subsidiaries or otherwise have a “qualifying event” with respect to a U.S. Welfare Plan on or prior to the Closing Date with any continuation of health benefits coverage which is required to be provided under Part 6 of Subtitle B of Title I of ERISA, or if applicable, Section 4980B of the Code (“COBRA”). “Qualifying beneficiaries” and “qualifying event ” shall have the meanings ascribed to those terms in COBRA.

8.8 Pension Plans. From and after the Closing, Sellers shall take any necessary measures to ensure, to the Purchaser’s reasonable satisfaction, that PPSS is not a participating employer to any Pension Plan, including the Pension Plan for Employees of Positron Industries Inc.

AMENDMENT TO PURCHASE AGREEMENT

THIS AMENDMENT TO PURCHASE AGREEMENT (this “Amendment”) is made as of February 28, 2007, to the PURCHASE AGREEMENT dated as of February 9, 2007, (the “Original Agreement”) by and among POSITRON INC., a company incorporated under the laws of Quebec (“PI”), POSITRON PUBLIC SAFETY SYSTEMS INC., a corporation incorporated under the laws of Canada (“PPSS” and collectively with PI, “Sellers”), IPC INFORMATION SYSTEMS HOLDINGS INC., a Delaware corporation (“IPC-US”), TSW COMMAND SYSTEMS, INC., a corporation incorporated under the laws of Canada (“IPC-Canada” and collectively with IPC-US, “Purchasers”), and IPC SYSTEMS, INC., a Delaware corporation (“IPC” and collectively with Purchasers, the “IPC Parties”). Capitalized terms used in this Agreement without definition shall have the meanings set forth or referenced in the Original Agreement.

WITNESSETH:

WHEREAS, Sellers and Purchasers desire to amend the Original Agreement, pursuant to Section 10.2 thereof, upon the terms and conditions hereinafter set forth.

NOW, THEREFORE, in consideration of the premises and the mutual promises contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending legally to be bound, hereby agree as follows:

1. Amendment to Original Agreement. The Original Agreement is hereby amended as follows:

(a) Amendment of Section 1.4 of the Original Agreement. Section 1.4 of the Original Agreement is hereby amended in its entirety as follows:

“1.4 Ordering of Transactions. Notwithstanding anything to the contrary, the parties agree that on the day immediately prior to the Closing Date and on the Closing Date the transactions contemplated by this Agreement shall be effected in the following order:

(b) Second, on the day immediately prior to the Closing Date, the purchase and sale of the PPSS Georgia Shares and the payment of the PPSS Georgia Shares Purchase Price;

(d) Fourth, on the day immediately prior to the Closing Date, the application of the amount of cash and cash equivalents (including the PPSS Georgia Shares Purchase Price) then held by PPSS to repay any Indebtedness owed by PPSS to PI (it being understood that PPSS Note and the PPSS Receivable will be converted into the Additional Shares pursuant to the Debt Conversion);

(e) Fifth, on the day immediately prior to the Closing Date, the distribution by PPSS to PI of any cash and cash equivalents not applied pursuant to Section 1.4(d), such distribution to be in the form of various dividends;

(f) Sixth, on the day immediately prior to the Closing Date, the contribution of cash by PI to PPSS as a capital contribution in an amount to be determined by PI in its sole discretion;

(g) Seventh, on the day immediately prior to the Closing Date, the distribution by PPSS to PI in a series of dividends in an aggregate amount equal to the contributions made to PPSS pursuant to Section 1.4(f); and

(h) Eight, on the Closing Date, the purchase and sale of the PPSS Shares and the payment of the PPSS Shares Purchase Price.

It is the intention and understanding among the parties hereto that the Company shall be transferred to Purchasers on a “cash-free” basis and that, for the purposes of this Section 1.4, “cash and cash equivalents” shall be determined on a “balance-sheet” basis as of the Closing, after giving effect to a reconciliation of such cash and cash equivalents to bank records, such reconciliation to be performed by Purchasers and PI jointly within 10 days after the Closing Date. The parties hereto shall take such actions as are reasonably required to give effect to such intention and understanding, and any discrepancy between the amount of cash and cash equivalents distributed to PI under this Section 1.4, and the amount of cash and cash equivalents of the Company as of the Closing shall be paid over by PI or the Company, as applicable, promptly after the completion of such reconciliation.”

(b) Amendment of Section 1.5(a) of the Original Agreement. The first sentence of Section 1.5(a) of the Original Agreement is hereby amended in its entirety as follows:

“(a) Closing Date Balance Sheet. Within ninety (90) calendar days after the Closing Date, PI shall prepare and deliver to IPC-Canada an unaudited consolidated balance sheet of the Company as of the opening of business on the

-2-

Closing Date and immediately prior to the Closing (the “Closing Date Balance Sheet”).

(c) Addition to Article I of the Original Agreement. Article I of the Original Agreement is hereby amended by adding the following as a new Section 1.6 thereof:

“1.6 Reimbursement of Amount Advanced for Bid Bond. At the Closing, Purchasers will reimburse PI for an advance in the amount of US $162,814.23, which was advanced by the Company to INCOG in the form of a bank draft in lieu of a bid bond required in connection with such bid. Following the Closing, in the event that such bank draft is returned to PI or in the event that INCOG reimburses PI for funds drawn on such bank draft, PI will promptly deliver such bank draft or such funds to the Company.”

(d) Amendment of Section 2.2(q) of the Original Agreement. Paragraph (iii) of Section 2.2(q) of the Original Agreement is hereby amended in its entirety as follows:

“(iii) The Company has paid all Taxes due as a result of its activities or has made adequate provision for such Taxes such that the reserves for current Taxes (excluding reserves for deferred Taxes) in respect of the period up to but not including the Closing Date or to any periods ending prior thereto (the “Pre-Closing Tax Period”) will not be less than the reasonably estimated Tax liability accruing or payable by the Company in respect of the Pre-Closing Tax Period.”

(e) Amendment of Section 5.1(a) of the Original Agreement. Section 5.1(a) of the Original Agreement is hereby amended in its entirety as follows:

“(a) The closing of the transactions contemplated hereby, other than the purchase and sale of the PPSS Georgia Shares (the “Closing”), shall take place at the offices of Xxxx, Xxxxxx & Xxxxxxxxx, LLP, 0 Xxxxx XxXxxxx Xxxxxx, Xxxxxxx, Xxxxxxxx, or if required by Purchasers’ lender, at the offices of Purchaser’s counsel, at 10:00 a.m., local time, on March 1, 2007, or at such other place, at such other time or on such other date as the parties may mutually agree. The date on which the Closing actually occurs is referred to herein as the “Closing Date”. The Closing shall be effective immediately prior to the opening of business on the Closing Date.”

(f) Amendment of Section 7.7 of the Original Agreement. Section 7.7 of the Original Agreement is hereby amended by adding the following as new paragraphs (e) and (f) thereof:

“(e) In the event that the trust created pursuant to Section 1 of the Escrow Agreement, as finally executed among the parties thereto, is not recognized by any court of competent jurisdiction or held invalid for any reason whatsoever and if PI is declared to have ownership in the Charged Property (as hereinafter defined), then as security for the performance by PI of the indemnification obligations, if any, of PI under Section 7.2 (the “Secured Obligations”), PI

-3-

hereby grants a hypothec without delivery (the “Hypothec”) in favor of the Purchasers in (i) the cash comprising the Escrow Amount (as defined in the Escrow Agreement) and (ii) all titles, documents, records and receipts evidencing the Escrow Amount (collectively, the “Charged Property”), for the sum of Cdn. $19,050,000 in lawful currency of Canada with interest thereon from the date hereof at the rate of 25% per annum (which sum and interest rate are solely for the purposes of the compliance with the applicable laws of the Province of Quebec and the laws of Canada). The full amount of the Hypothec shall be and remain continuing collateral security in favor of the Purchasers notwithstanding the fact that all or part of the Secured Obligations arise prior to, at the time of or subsequent to the execution of this Amendment. The Hypothec is a continuous security which shall subsist notwithstanding any fluctuation of the amounts hereby secured. PI and Purchasers shall use their commercially reasonable efforts to cause the Escrow Agent to take such actions as are reasonably requested by the Purchasers in order to give effect to the Hypothec. This Section 7.7(e), as well as the enforcement of and the recourses related to the Hypothec, shall be governed by and construed in accordance with the laws of the Province of Quebec and the laws of Canada applicable therein. The Hypothec will expire upon the distribution of the entire Escrow Amount by the Escrow Agent in accordance with the terms of the Escrow Agreement. This Section 7.7(e) does not expand or contract the obligations of PI or the rights of the Purchaser Indemnified Parties under Article VII or the Escrow Agreement.

(f) As security for the Secured Obligations, PI hereby grants to Purchasers a first priority security interest in and to the Charged Property and any investments or reinvestments of Charged Property. PI authorizes the filing of any financing statements that the Purchasers may deem appropriate covering the Charged Property, any investments or reinvestments of Charged Property, or any part thereof. The security interest granted hereby will expire upon the distribution of the entire Escrow Amount by the Escrow Agent in accordance with the terms of the Escrow Agreement. This Section 7.7(f) does not expand or contract the obligations of PI or the rights of the Purchaser Indemnified Parties under Article VII or the Escrow Agreement.”

(g) Amendment of Section 8.3(c) of the Original Agreement. Section 8.3(c) of the Original Agreement is hereby amended in its entirety as follows:

“(c) The provisions of Section 7.4 to the contrary notwithstanding, PI shall control all proceedings (including selection of counsel and accountants) taken in connection with any Tax Audit or negotiations with U.S. state Tax authorities regarding entering into a voluntary compliance or disclosure or similar agreement (a “VDA”) with respect to tax periods of the Company ending on or prior to the Closing Date, and shall have the right to initiate negotiations with respect to any such VDA, but shall not without the prior consent of Purchasers (which consent shall not be unreasonably withheld, conditioned or delayed) (i) in connection with such negotiations take any action (including entering into any- VDA) that

-4-

obligates the Company with respect to any post-Closing Tax period or (ii) conclude any agreement that relates to “trust fund” Taxes (i.e., Taxes for which applicable law requires the Company to withhold amounts from third parties and remit the same to a Tax authority); provided, however, that PI shall provide Purchasers the opportunity to participate, as may reasonably be requested by Purchasers, with PI in contesting any Tax Audit or in negotiating any VDA to the extent such Tax Audit or VDA may adversely affect the Company in any Tax period (or portion thereof) beginning on or after the Closing Date. Notwithstanding the foregoing, neither PI nor the Purchasers shall settle or compromise, nor shall permit the Company to settle or compromise, any Tax Audit without the other party’s prior consent (which consent shall not be unreasonably withheld, conditioned or delayed). Prior to holding any discussions with any Tax authority relating to a potential VDA, PI shall notify Purchasers of PI’s intent to enter into a VDA and shall advise Purchasers of the proposed terms of the VDA. Each party’s participation in any Tax Audit or VDA negotiation shall be at its own expense. Each of the parties agrees to provide the other parties with a copy of any written communication received from any Governmental Authority relating to the taxation the Company within ten (10) calendar days of its receipt of such communication.”

(h) Amendment of Section 10.7 of the Original Agreement. Section 10.7 of the Original Agreement is hereby amended in its entirety as follows:

“10.1 Governing Law. SAVE AND EXCEPT FOR SECTION 7.7(e) OF THIS AGREEMENT, ALL QUESTIONS CONCERNING THE CONSTRUCTION, VALIDITY AND INTERPRETATION OF THIS AGREEMENT AND EACH OF THE ANCILLARY DOCUMENTS (OTHER THAN THE AGREEMENT OF PURCHASE AND SALE) SHALL BE GOVERNED BY AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICTS OF LAW PRINCIPLES OF SUCH STATE.”

2. Miscellaneous.

(a) Full Force and Effect. Except as expressly set forth herein, this Amendment does not constitute a waiver or modification of any provision of the Original Agreement. Except as expressly amended hereby, the Original Agreement shall continue in full force and effect in accordance with the provisions thereof on the date hereof. As used in the Original Agreement, the terms “this Agreement,” “herein,” “hereof,” “hereinafter,” “hereto” and words of similar import, shall, unless the context otherwise requires, mean the Original Agreement as amended by the Amendment. References to the terms “Agreement” appearing in the Exhibits or Schedules to the Original Agreement, shall, unless the context otherwise requires, mean the Original Agreement as amended by this Amendment.

(b) Headings and Terms. The headings in this Amendment are for purposes of reference only and shall not be considered in construing this Amendment. Terms defined in the singular shall have a comparable meaning when used in the plural, and vice versa.

-5-

(c) Counterparts. This Amendment may be executed in any number of counterparts, each of which when so executed and delivered shall constitute an original and all together shall constitute one agreement.

(d) Law Governing. This Amendment shall be construed and enforced in accordance with and shall be governed by the laws of the State of New York, without giving effect to its conflict of laws provisions.
