                paid in

                by
                Section 3.1(b)
                on
                the Exchangeable Shares, the Board of Directors may, in good faith

                required
                regulatory approvals, subdivide, redivide or change (the "Subdivision")
                each issued and unissued Exchangeable Share on the basis that each
                Exchangeable Share before the subdivision becomes a number of Exchangeable
                Shares equal to the sum of (i) one Acquirer Share and (ii) the

                the

                Directors

                Callco must notify the Corporation of its determination to do so
                (the
                "Callco Call Notice") within three Business Days of receipt by the
                Corporation of the Retraction Request. If Callco does not so notify
                the
                Corporation within such three Business Day period, the Corporation
                will
                notify the Holder as soon as possible thereafter that Callco will
                not
                exercise the Retraction Call Right. If Callco delivers the Callco
                Call
                Notice within such three Business Day period, and provided that the
                Retraction Request is not revoked by the Holder in the manner specified
                in
                Section 6.7,
                the Retraction Request shall thereupon be considered only to be an
                offer
                by the Holder to sell all but not less than all the Retracted Shares
                to
                Callco in accordance with the Retraction Call Right. In such event,
                the
                Corporation shall not redeem the Retracted Shares and Callco shall
                purchase from such holder and such holder shall sell to Callco on
                the
                Retraction Date all but not less than all the Retracted Shares for
                a
                purchase price (the "Purchase Price") per share equal to the Retraction
                Price, which, as set forth in Section 6.4,
                shall be fully paid and satisfied by the delivery by or on behalf
                of
                Callco, of the Exchangeable Share Consideration representing the
                total
                Purchase Price. For the purposes of completing a purchase pursuant
                to the
                Retraction Call Right, Callco shall deposit with the Transfer Agent,
                on or
                before the Retraction Date, the Exchangeable Share Consideration
                representing the total Purchase Price. Provided that Callco has complied
                with Section 6.4,
                the closing of the purchase and sale of the Retracted Shares pursuant
                to
                the Retraction Call Right shall be deemed to have occurred as at
                the close
                of business on the Retraction Date and, for greater certainty, no
                redemption by the Corporation of such Retracted Shares shall take
                place on
                the Retraction Date. In the event that Callco does not deliver a
                Callco
                Call Notice within such three Business Day period, and provided that
                the
                Retraction Request is not revoked by the holder in the manner specified
                in
                Section 6.7,
                the Corporation shall redeem the Retracted Shares on the Retraction
                Date
                and in the manner otherwise contemplated in this Article 6.

              The

                the
                Transfer Agent to deliver to the relevant Holder, at the address
                of the
                Holder recorded in the register of the Corporation for the Exchangeable
                Shares or at the address specified in the Holder's Retraction Request
                or,
                if specified in such Retraction Request, by holding for pick-up by
                the

                of the

                holder of Exchangeable Shares, the Exchangeable Share Consideration
                representing the total Retraction Price or the total Purchase Price,
                as
                the case may be, and such delivery of such Exchangeable Share
                Consideration to the Transfer Agent shall be deemed to be payment
                of and
                shall satisfy and discharge all liability for the total Retraction
                Price
                or total Purchase Price, as the case may be, to the extent that the
                same
                is represented by such Exchangeable Share
                Consideration.

              On
                and after the close of business on the Retraction Date, the holder
                of the
                Retracted Shares shall cease to be a holder of such Retracted Shares
                and
                shall not be entitled to exercise any of the rights of a holder in
                respect
                thereof, other than the right to receive the total Retraction Price
                or
                total Purchase Price, as the case may be, unless upon presentation
                and

                payment of the total Retraction Price or the total Purchase Price,
                as the
                case may be, shall not be made as provided in Section 6.4,
                in which case the rights of such holder shall remain unaffected until
                the
                total Retraction Price or the total Purchase Price, as the case may
                be,
                has been paid in the manner hereinbefore provided. On and after the
                close
                of business on the Retraction Date, provided that presentation and
                surrender of certificates and payment of the total Retraction Price
                or the
                total Purchase Price, as the case may be, has been made in accordance
                with
                the foregoing provisions, the holder of the Retracted Shares so redeemed
                by the Corporation or purchased by Callco shall thereafter be considered
                and deemed for all purposes to be the holder of Acquirer Shares delivered
                to it.

              Notwithstanding
                any other provision of this Article 6,
                the Corporation shall not be obligated to redeem Retracted Shares
                specified by a holder in a Retraction Request to the extent that
                such
                redemption of Retracted Shares would be contrary to solvency requirements
                or other provisions of applicable law. If the Corporation believes,
                acting
                reasonably, that on any Retraction Date it would not be permitted
                by any
                of such provisions to redeem the Retracted Shares tendered for redemption
                on such date, and provided that Callco shall not have exercised the
                Retraction Call Right with respect to the Retracted Shares, the
                Corporation shall only be obligated to redeem Retracted Shares specified
                by a holder in a Retraction Request to the extent of the maximum
                number
                that may be so redeemed (rounded down to a whole number of shares)
                as
                would not be contrary to such provisions and shall notify the holder
                at
                least two Business Days prior to the Retraction Date as to the number
                of
                Retracted Shares which will not be redeemed by the Corporation. In
                any
                case in which the redemption by the Corporation of Retracted Shares
                would
                be contrary to solvency requirements or other provisions of applicable
                law, the Corporation shall redeem the maximum number of Exchangeable
                Shares which the Board of Directors determines the Corporation is
                permitted to redeem as of the Retraction Date on a pro rata basis
                and
                shall issue to each holder of Retracted Shares a new certificate,
                at the
                expense of the Corporation, representing the Retracted Shares not
                redeemed
                by the Corporation pursuant to Section 6.2.
                Provided that the Retraction Request is not revoked by the holder
                in the
                manner specified in Section 6.7
                and Callco does not exercise the Retraction Call Right, the holder
                of any
                such Retracted Shares not redeemed by the Corporation pursuant to
                Section 6.2
                as
                a result of solvency requirements or other provisions of applicable
                law
                shall be deemed by giving the Retraction Request to have instructed
                the
                Trustee to require Acquirer to purchase such Retracted Shares from
                such
                holder on the Retraction Date or as soon as practicable thereafter
                on
                payment by Acquirer to such holder of the Retraction Price for each
                such
                Retracted Share, all as more specifically provided in the Voting
                and

    REDEMPTION
      OF EXCHANGEABLE SHARES BY THE CORPORATION

     

    
      	
              7.1

            	
              Subject
                to applicable law, and provided Callco has not exercised the Redemption
                Call Right, the Corporation shall on the Redemption Date redeem all
                but
                not less than all of the then outstanding Exchangeable Shares for
                an
                amount per share equal to the Exchangeable Share Price applicable
                on the
                last Business Day prior to the Redemption Date (the "Redemption
                Price").

            

    

     

    
      	
              7.2

            	
              In
                any case of a redemption of Exchangeable Shares under this Article 7,
                the Corporation shall, at least 45 days before the Redemption Date
                (other than a Redemption Date established in connection with an Acquirer
                Control Transaction or an Exchangeable Share Voting Event), send
                or cause
                to be sent to each holder of Exchangeable Shares a notice in writing
                of
                the redemption by the Corporation or the purchase by Callco under
                the
                Redemption Call Right, as the case may be, of the Exchangeable Shares
                held
                by such holder. In the case of a Redemption Date established in connection
                with an Acquirer Control Transaction, the written notice of redemption
                by
                the Corporation or the purchase by Callco under the Redemption Call
                Right
                will be sent on or before the Redemption Date, on as many days prior
                written notice as may be determined by the Board of Directors to
                be
                reasonably practicable in the circumstances. In any such case, such
                notice
                shall set out the formula for determining the Redemption Price or
                the
                Redemption Call Purchase Price, as the case may be, the Redemption
                Date
                and, if applicable, particulars of the Redemption Call Right. In
                the case
                of any notice given in connection with a possible Redemption Date,
                such
                notice will be given contingently and will be withdrawn if the contingency
                does not occur.

              On

                of the
                Redemption Call Right, the Corporation shall cause to be delivered
                to the
                holders of the Exchangeable Shares to be redeemed the Redemption
                Price for

                registered office of the Corporation or at any office of the Transfer
                Agent as may be specified by the Corporation in the notice described
                in
                Section 6.7
                of
                the certificates representing such Exchangeable Shares, together
                with such
                other documents and instruments as may be required to effect a transfer
                of
                Exchangeable Shares under the ABCA and the articles and by-laws of
                the
                Corporation and such additional documents and instruments as the
                Transfer
                Agent and the Corporation may reasonably require. Payment of the
                total
                Redemption Price for such Exchangeable Shares shall be made by delivery
                to
                each Holder, at the address of the Holder recorded in the securities
                register of the Corporation or by holding for pick-up by the Holder
                at the
                registered office of the Corporation or at any office of the Transfer
                Agent as may be specified by the Corporation in such notice, on behalf
                of
                the Corporation of the Exchangeable Share Consideration representing
                the
                total Redemption Price. On and after the Redemption Date, the holders
                of
                the Exchangeable Shares called for redemption shall cease to be holders
                of
                such Exchangeable Shares and shall not be entitled to exercise any
                of the
                rights of holders in respect thereof, other than the right to receive
                their proportionate part of the total Redemption Price, unless payment
                of
                the total Redemption Price for such Exchangeable Shares shall not
                be made
                upon presentation and surrender of certificates in accordance with
                the
                foregoing provisions, in which case the rights of the holders shall
                remain
                unaffected until the total Redemption Price has been paid in the
                manner
                hereinbefore provided. The Corporation shall have the right at any
                time
                after the sending of notice of its intention to redeem the Exchangeable
                Shares as aforesaid to deposit or cause to be deposited the Exchangeable
                Share Consideration with respect to the Exchangeable Shares so called
                for
                redemption, or of such of the said Exchangeable Shares represented
                by
                certificates that have not at the date of such deposit been surrendered
                by
                the holders thereof in connection with such redemption, in a custodial
                account with any chartered bank or trust company in Canada named
                in such
                notice. Upon the later of such deposit being made and the Redemption
                Date,
                the Exchangeable Shares in respect whereof such deposit shall have
                been
                made shall be redeemed and the rights of the holders thereof after
                such
                deposit or Redemption Date, as the case may be, shall be limited
                to
                receiving their proportionate part of the total Redemption Price
                for such
                Exchangeable Shares so deposited, against presentation and surrender
                of
                the said certificates held by them, respectively, in accordance with

                Date (the "Liquidation Call Purchase Price") in accordance with Section
                5.1. In the event of the exercise of the Liquidation Call Right by
                Callco,
                each Holder shall be obligated to sell all the Exchangeable Shares
                held by
                such Holder to Callco on the Liquidation Date upon payment by Callco

              To
                exercise the Liquidation Call Right, Callco must notify the Corporation
                and the Transfer Agent of Callco's intention to exercise such right
                at
                least 45 days before the Liquidation Date, in the case of a voluntary
                liquidation, dissolution or winding-up of the Corporation or any
                other
                voluntary distribution of the assets of the Corporation among its
                shareholders for the purpose of winding-up its affairs, and at least
                five
                Business Days before the Liquidation Date, in the case of an involuntary
                liquidation, dissolution or winding-up of the Corporation or any
                other
                involuntary distribution of the assets of the Corporation among its
                shareholders for the purpose of winding up its affairs. The Transfer
                Agent
                will notify the holders of Exchangeable Shares as to whether Callco
                has
                exercised the Liquidation Call Right forthwith after the expiry of
                the
                period during which the same may be exercised by Callco. If Callco
                exercises the Liquidation Call Right, then on the Liquidation Date,
                Callco
                will purchase and the holders of Exchangeable Shares will sell all
                of the
                Exchangeable Shares then outstanding for a price per Exchangeable
                Share

                Price.

                the purposes of completing the purchase of the Exchangeable Shares

                has been so deposited with the Transfer Agent, on and after the

                holders of the Exchangeable Shares and shall not be entitled to exercise
                any of the rights of holders in respect thereof (including any rights

                Shares
                to which such Holder is entitled. Upon surrender to the Transfer
                Agent of
                a certificate or certificates representing Exchangeable Shares, together
                with such other documents and instruments as may be required to effect

                by
                Callco, each holder of Exchangeable Shares shall be obligated to
                sell all

                exercise the Redemption Call Right, Callco must notify the Transfer
                Agent
                and the Corporation of Callco's intention to exercise such right

      CONSULTING AGREEMENT 

     

     

    THIS
      BUSINESS CONSULTING AGREEMENT made this 7th day of August 2006 (the “Effective
      Date”), by and between: Invisa, Inc., (hereinafter referred to as the “COMPANY”)
      and John Anderson, an individual engaged in providing Financial Investor
      relations services (hereinafter referred to as “CONSULTANT”). 

     

     

    WITNESSETH
      THAT: 

     

     

    WHEREAS,
      the COMPANY requires Financial Investor relations services and desires to employ
      CONSULTANT, as an independent contractor consultant, to provide such services,
      and CONSULTANT is agreeable to such employment, and the parties desire a written
      document formalizing their relationship and evidencing the terms of their
      agreement: 

     

     

    NOW,
      THEREFORE, intending to be legally bound, and in consideration of the mutual
      promises and covenants, the parties have agreed as follows: 

     

     

    1.
      APPOINTMENT.
      The

      conditions of this Agreement. CONSULTANT accepts such appointment and agrees
      to
      perform the services upon the terms and conditions of this Agreement.

     

     

    2.
      TERM.
      The term
      of this Agreement shall begin on or before August 16, 2006 and shall terminate

    6.
      REPRESENTATION
      AND INDEMNIFICATIONS.
      (a) The
      Company shall be deemed to make a continuing representation of the accuracy
      of
      any and all material facts, material, information, and data, which it supplies
      to CONSULTANT and the COMPANY, acknowledges its awareness that CONSULTANT will
      rely on such continuing representation in disseminating such information and
      otherwise performing it public relations functions. 

     

     

    (b)
      Consultant, in the absence of notice in writing from COMPANY, will rely on
      the
      continuing accuracy of the material, information, and data supplied by the
      COMPANY. 

     

     

    (c)
      COMPANY hereby agrees to indemnify CONSULTANT against, and to hold CONSULTANT

      of
      CONSULTANTS reliance on the general availability of information supplied to
      CONSULTANT and CONSULTANT’S ability to promulgate such information, unless
      CONSULTANT has been negligent in fulfilling his duties and obligations
      hereunder. 

     

     

    7.
      COMPENSATION.
      (a) For
      all general services described herein, COMPANY shall compensate CONSULTANT
      by
      issuing to CONSULTANT Six Hundred Eighty One Thousand Eight Hundred (“681,800”)

      be registered by a registration statement filed on form S-8 before issuance
      of
      said shares on or following the Effective Date of this Agreement. The parties
      acknowledge that in negotiating this fee they recognize that the services will
      probably not be performed in equal monthly segments, but may be more substantial
      during the early portion of the term and less thereafter as relationships and
      communications lines are established. Thus, part of the compensation for earlier
      services will be deferred and the lessening of services shall not constitute
      a
      breach or termination hereof, but the level fee shall continue. 

     

     

    (b)
      For
      all special services, not within the scope of this Agreement, COMPANY shall
      pay
      CONSULTANT such fee as, and when, the parties shall determine in advance of
      performance of the special services provided that COMPANY has agreed in advance
      for the special services. 

     

     

    

     

     

    8.

      OF PARTIES.
      CONSULTANT is an independent contractor, responsible for compensation of its
      agents, employees and representatives, as well as all applicable withholding
      therefrom and taxes thereon (including unemployment compensation) and all
      workers’ compensation insurance. This Agreement does not establish any
      partnership, joint venture, or other business entity or association between
      the
      parties and neither party is intended to have any interest in the business
      or
      property of the other. 

     

     

    9.
      TERMINATION.
      This
      agreement may not be terminated by either party prior to the expiration of
      the

    10.
      ATTORNEY’S
      FEES.
      Should
      either party default in the terms or conditions of this Agreement and suit
      be
      filed as a result of such default, the prevailing party shall be entitled to
      recover all costs incurred as a result of such default including all costs
      and
      reasonable attorney’s fees, expenses and court costs through trial and appeal.

     

     

    11.
      WAIVER
      OF
      BREACH.
      The
      waiver by either party of a breach of any provision of the Agreement by the
      other party shall not operate to be construed as a waiver of any subsequent
      breach by the other party. 

     

     

    12.
      ASSIGNMENT.
      The
      rights and obligations of the parties under this Agreement shall inure to the

      sufficient if in writing, and if sent by certified mail, return receipt
      requested, to the principal office of the party being notified. 

     

     

    14.
      ENTIRE
      AGREEMENT.
      This
      instrument contains the entire agreement of the parties and may be modified
      only
      by agreement, in writing, signed by the party against whom enforcement of any
      waiver, change, modification, extension or discharge is sought. This Agreement
      shall be governed for all purposes by the laws of the State of California.
      If
      any provision of this Agreement is declared void, such provision shall be deemed
      severed from this Agreement, which shall otherwise remain in full force and
      effect. 

     

     

    IN
      WITNESS WHEREOF, the parties hereto, intending to be legally bound, have
      executed this Agreement.
