(a) Each Trizec Common Share held in treasury and not outstanding and each Trizec Common Share that is owned by MergerCo immediately prior to the Trizec Merger Effective Time shall be cancelled and retired and shall cease to exist, without any conversion thereof and no payment or distribution shall be made with respect thereto.

(b) Each Trizec Common Share held by TZ Canada or any TZ Canada Subsidiaries, Parent, and AcquisitionCo immediately prior to the Trizec Merger Effective Time shall continue to remain an issued and outstanding share of common stock of the Surviving Corporation, without any conversion thereof and no payment or distribution shall be made with respect thereto.

Immediately after the completion of the Trizec Merger, in accordance with the terms of the Surviving Corporation Charter, the Surviving Corporation shall cause each Redeemable Preferred Share to be redeemed for the right to receive cash in the amount of (i) $29.01 per share, plus (ii) an amount equal to $0.20 multiplied by the quotient obtained by dividing (x) the number of days between the last day of the quarter for which a full quarterly dividend on the Trizec Common Shares has been declared and the Closing Date (including the Closing Date), by (y) the total number of days in the quarter in which the Closing Date occurs, without interest (the “Redemption Amount”), without interest subject to any applicable Taxes required to be withheld in accordance with Section 3.09 with respect to such payment and payable upon surrender, in the manner provided in Section 3.05, of the certificate evidencing the Trizec Common Shares that are to be so converted into the Trizec Common Share Merger Consideration (the “Trizec Common Share Certificates”).

(d) Each share of special voting stock, par value $0.01 per share, of Trizec (“Trizec Special Voting Stock”) issued and outstanding immediately prior to the Trizec Merger Effective Time shall continue to remain issued and outstanding as a share of special voting stock, par value $0.01 per share, of the Surviving Corporation.

(e) Each share of Class F convertible stock, par value $0.01 per share, of Trizec (“Trizec Class F Stock”) issued and outstanding immediately prior to the Trizec Merger Effective Time shall continue to remain issued and outstanding as a share of Class F convertible stock, par value $0.01 per share, of the Surviving Corporation.

(f) Immediately prior to the Trizec Merger Effective Time, each outstanding qualified or nonqualified option to purchase Trizec Common Shares (“Trizec Stock Options”) under the 2002 Trizec Properties, Inc. Long-Term Incentive Plan, as amended and restated, and any employee or director share option or compensation plan or arrangement of Trizec (collectively, “Incentive Plans”), shall become fully vested and exercisable or payable, as the case may be (whether or not then vested or subject to any performance condition that has not been satisfied, and regardless of the exercise price thereof). At the Trizec Merger Effective Time, each Trizec Share Option not theretofore exercised shall be cancelled in exchange for the right to receive a single lump sum cash payment, equal to the product of (i) the number of Trizec Common Shares subject to such Trizec Share Option immediately prior to the Trizec Merger Effective Time, whether or not vested or exercisable, and (ii) the

-20-

excess, if any, of the Redemption Amount over the exercise price per share of such Trizec Share Option, without interest (the “Trizec Option Consideration”), subject to any applicable Taxes required to be withheld in accordance with Section 3.09 with respect to such payment.

(h) All restricted share unit, deferred restricted share unit, restricted share rights and deferred restricted share rights awards (collectively, “Trizec Restricted Share Rights”) granted pursuant to the Incentive Plans or otherwise automatically shall become fully vested and free of any forfeiture restrictions immediately prior to the Trizec Merger Effective Time, and each Trizec Restricted Share Right shall be considered an outstanding Trizec Common Share for all purposes of this Agreement, including the right to receive the Common Share Merger Consideration. Payment of the Common Share Merger Consideration in respect of any Trizec Restricted Share Rights shall be performed in accordance with Section 8.06(d).

(i) Immediately prior to the Trizec Merger Effective Time, the terms of each outstanding warrant to purchase Trizec Common Shares (“Trizec Warrants”) (other than such Trizec Warrants that are held by TZ Canada or any TZ Canada Subsidiaries immediately prior to the Trizec Merger Effective Time), shall be adjusted in accordance with Section Eight of the warrant agreement with respect to each Trizec Warrant, to provide that from and after the Trizec Merger Effective Time, each such Trizec Warrant shall entitle the holder thereof upon exercise of such Trizec Warrant and payment of the exercise price thereof to receive solely, in full satisfaction thereof, a single lump sum cash payment, equal to the product of (i) the number of Trizec Common Shares subject to such Trizec Warrant immediately prior to the Trizec Merger Effective Time, whether or not vested or exercisable, and (ii) the Redemption Amount, without interest (the “Trizec Warrant Consideration”), and subject to any applicable Taxes required to be withheld in accordance with Section 3.09 with respect to such payment. If the exercise price per share of any such Trizec Warrant is equal to or greater than the Redemption Amount, such Trizec Warrant shall be cancelled without any cash payment being made in respect thereof.

(a) From and after the Trizec Merger Effective Time, for all purposes of determining the record holders of the Redeemable Preferred Shares, the holders of Merger Shares as of immediately prior to the Trizec Merger Effective Time shall be deemed to be holders of the Redeemable Preferred Shares. No share certificates shall be issued in respect of the Redeemable Preferred Shares, and such shares shall be evidenced by the certificates representing the Merger Shares (the “Trizec Common Share Certificates”). Promptly after the completion of the Trizec Merger, the holders of Merger Shares as of immediately prior to the Trizec Merger Effective Time shall be entitled to receive a payment representing the aggregate Redemption Amount payable in respect of the Redeemable Preferred Shares into which their Trizec Common Shares were converted, upon surrender of the Trizec Common Share Certificates (which at and after the Trizec Merger Effective Time will represent Redeemable Preferred Shares) in accordance with this Section 3.05.

Immediately following completion of the Trizec Merger, the redemption of the Redeemable Preferred Shares and the cancellation of the Trizec Stock Options and applicable Trizec Warrants, Parent shall cause to be deposited with the Trizec Paying Agent, (i) by the Surviving Corporation for the benefit of the holders of Redeemable Preferred Shares, Trizec Stock Options, Trizec Restricted Shares, Trizec Restricted Share Rights and applicable Trizec Warrants, cash in an amount sufficient to pay the aggregate Trizec Consideration required to be paid (such cash being hereinafter referred to as the “Surviving Corporation Redemption

-23-

If applcaible, each of the Surviving Corporation Redemption Fund and the Surviving Operating Company Redemption Fund shall be invested by the Trizec Paying Agent as directed by and for the benefit of the Surviving Corporation and the Surviving Operating Company, respectively; provided, however, that no gain or loss thereon shall affect the amounts payable to the holders of Redeemable Preferred Shares, Trizec Stock Options, Existing Units and applicable Trizec Warrants following completion of the Trizec Merger pursuant to this Article III. Any and all interest and other income earned on the Surviving Corporation Redemption Fund and the Surviving Operating Company Redemption Fund shall promptly be paid to the Surviving Corporation.

(c) As promptly as practicable after the Trizec Merger Effective Time, Parent and the Surviving Corporation shall cause the Trizec Paying Agent to mail to each person who was, as of immediately prior to the Trizec Merger Effective Time, a holder of record of the Merger Shares, Trizec Warrants and Existing Units: (i) a letter of transmittal (which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to, if applicable, the Trizec Common Share Certificates, Existing Unit certificates or Trizec Warrant certificates shall pass, only upon proper delivery of, if applicable, the Trizec Common Share Certificates, Existing Unit certificates or Trizec Warrant certificates to the Trizec Paying Agent) and (ii) instructions for effecting the surrender of, if applicable, the Trizec Common Share certificates, Existing Unit certificates or Trizec Warrant certificates in exchange for the Trizec Consideration. Upon surrender to the Trizec Paying Agent of Trizec Common Share Certificates or, Existing Unit certificates or Trizec Warrant certificates for cancellation, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Trizec Common Share Certificate, Existing Unit certificates or Trizec Warrant certificate shall be entitled to receive in exchange therefor, in cash, or units, as applicable, the Redemption Amount in respect of the Redeemable Preferred Shares issued in the Trizec Merger and redeemed immediately following the Trizec Merger, the right to receive the Trizec Warrant Consideration or the right to receive the Operating Company Merger Consideration, as applicable, and the Trizec Common Share Certificate or Trizec Warrant certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Merger Shares or Trizec Warrants that is not registered in the transfer records of Trizec, payment of the Redemption Amount in respect of the Redeemable Preferred Shares redeemed immediately following the Trizec Merger or cash amount in respect of the Trizec Warrants issued in the Trizec Merger may be made to a person other than the person in whose name the

-24-

Trizec Common Share Certificate or Trizec Warrant certificate so surrendered is registered if such Trizec Common Share Certificate or Trizec Warrant certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the payment of the Redemption Amount in respect of the Redeemable Preferred Shares issued in the Trizec Merger and redeemed immediately following the Trizec Merger or the payment of the Trizec Warrant Consideration to a person other than the registered holder of such Trizec Common Share Certificate or Trizec Warrant certificate or establish to the reasonable satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. Until surrendered as contemplated by this Section 3.05, each Trizec Common Share Certificate, Existing Unit certificate and Trizec Warrant certificate shall be deemed at all times after the Trizec Merger Effective Time to represent only the right to receive upon such surrender the applicable Trizec Consideration and, at all times after the redemption of the Redeemed Preferred Shares, the Redemption Amount to which the holder of such Trizec Common Share Certificate is entitled following redemption of the Redeemable Preferred Shares, or the Trizec Warrant Consideration or Operating Company Merger Considration, as applicable. No interest shall be paid or will accrue on any cash payable to holders of Trizec Common Share Certificates, Existing Unit certificates or the Trizec Warrant Consideration pursuant to the provisions of this Article III.

(d) Any portion of the Surviving Corporation Redemption Fund deposited with the Trizec Paying Agent pursuant to Section 3.05(a) to pay for Merger Shares that become Trizec Dissenting Shares shall be delivered to the Surviving Corporation upon demand; provided, however, that the Surviving Corporation shall remain liable for payment of the Redemption Amount for the Trizec Common Share Merger Consideration in respect of Trizec Common Shares held by any stockholder who shall have failed to perfect or who otherwise shall have withdrawn or lost such stockholder’s rights to appraisal of such shares under Section 262 of the DGCL (“Section 262”).

(e) Any portion of the Surviving Corporation Redemption Fund that remains undistributed to the holders of Redeemable Preferred Shares for one year after the Trizec Merger Effective Time shall be delivered to the Surviving Corporation, upon demand, and any holders of Redeemable Preferred Shares who have not theretofore complied with this Article III shall thereafter look only to the Surviving Corporation for, and the Surviving Corporation shall remain liable for, payment of their claim for the Redemption Amount. Any portion of the Surviving Corporation Redemption Fund remaining unclaimed by holders of Redeemable Preferred Shares as of a date which is immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Authority shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation free and clear of any claims or interest of any person previously entitled thereto. None of Parent, the Trizec Paying Agent or the Surviving Corporation shall be liable to any holder of Redeemable Preferred Shares for any such shares (or dividends or

-25-

distributions with respect thereto), or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(f) If any Trizec Common Share Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Trizec Common Share Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Trizec Common Share Certificate, the Trizec Paying Agent shall pay in respect of Redeemable Preferred Shares into which the Trizec Common Shares were converted in the Trizec Merger to which such lost, stolen or destroyed Trizec Common Share Certificate relate the Redemption Amount to which the holder thereof is entitled.

-27-

provision of state, local or foreign tax law. To the extent that amounts are so withheld by Trizec, the Surviving Corporation, or the Trizec Paying Agent, as applicable, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Merger Shares, Redeemable Preferred Trizec Common Shares, Trizec Stock Options, Trizec Restricted Share Rights, Trizec Warrants, or Trizec Dissenting Shares in respect of which such deduction and withholding was made by the Trizec, the Surviving Corporation or the Trizec Paying Agent, as applicable.

Each of Trizec, TZ Canada and Parent shall furnish all information concerning itself and its affiliates that is required to be included in the Proxy Statement or, to the extent applicable, the Other Filings, or that is customarily included in proxy statements prepared in connection with transactions of the type contemplated by this Agreement.

-70-

use its reasonable best efforts to cause the definitive Proxy Statement to be cleared by the SEC and mailed to Trizec’s stockholders as promptly as reasonably practicable following clearance from the SEC. Trizec shall promptly notify TZ Canada and Parent upon the receipt of any comments from the SEC or its staff or any request from the SEC or its staff for amendments or supplements to the Proxy Statement or the Other Filings and shall promptly provide TZ Canada and Parent with copies of all correspondence between Trizec and its representatives, on the one hand, and the SEC and its staff, on the other hand, relating to the Proxy Statement or the Other Filings. If at any time prior to the Trizec Stockholders’ Meeting, any information relating to Trizec, TZ Canada or the Buyer Parties or any of their respective affiliates, officers, members or directors, should be discovered by Trizec, TZ Canada or Parent which should be set forth in an amendment or supplement to the Proxy Statement or the Other Filings, so that the Proxy Statement or the Other Filings shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, the party which discovers such information shall promptly notify the other parties, and an appropriate amendment or supplement describing such information shall be filed with the SEC and, to the extent required by applicable Law, disseminated to the stockholders of Trizec. Notwithstanding anything to the contrary stated above, prior to filing or mailing the Proxy Statement or filing the Other Filings (or any amendment or supplement thereto) or responding to any comments of the SEC with respect thereto, Trizec shall provide Parent a reasonable opportunity to review and comment on such document or response and will in good faith consider such comments, and to the extent practicable, Trizec will provide TZ Canada and Parent with the opportunity to participate in any substantive calls between Trizec, or any of its representatives, and the SEC concerning the Proxy Statement.

(b) Trizec shall duly call, give notice of, convene and hold a meeting of its stockholders (including any adjournments or postponements thereof, the “Trizec Stockholders’ Meeting”), as promptly as practicable after the date of this Agreement, for the purpose of voting upon the adoption of this Agreement. Subject to the following sentence, (i) the Trizec Board shall recommend to holders of the Shares that they adopt this Agreement (the “Trizec Recommendation”), and include such recommendation in the Proxy Statement, and (ii) Trizec will use its reasonable best efforts to solicit from its stockholders proxies in favor of the adoption of this Agreement and will use its reasonable best efforts to take all other action necessary or advisable to secure the Trizec Stockholder Approval. Notwithstanding anything in this Agreement to the contrary, the Trizec Board or the Special Committee may determine (1) not to make or to withdraw, modify or change such recommendation (a “Trizec Change in Recommendation”), and (2) not to use such efforts to solicit proxies or take such other necessary or advisable actions in favor of the adoption of this Agreement if, in the case of both clauses (1) and (2), it has determined in good faith, after consultation with its outside legal counsel, that failure to take such action would be inconsistent with its fiduciary duties under applicable Law. Unless this Agreement has been terminated in accordance with Section 10.01, Trizec shall hold the Trizec

-71-

Stockholders’ Meeting regardless of whether the Trizec Board has made a Trizec Change in Recommendation. If there are an insufficient number of Trizec Common Shares represented in person or by proxy at the Trizec Stockholders’ Meeting to constitute a quorum or to adopt this Agreement, Trizec may adjourn or postpone, as applicable, the Trizec Stockholders’ Meeting for up to ten (10) business days so long as, during such period, Trizec uses its reasonable best efforts to obtain a quorum and the requisite vote to adopt this Agreement as promptly as practicable. Trizec may, if it receives a bona fide written unsolicited Trizec Acquisition Proposal, delay the mailing of the Proxy Statement or the holding of the Trizec Stockholders’ Meeting, in each case for such reasonable period as would provide a reasonable opportunity for the Trizec Board and/or the Special Committee to consider such Trizec Acquisition Proposal and to determine the effect, if any, on the Trizec Recommendation (but in any event not longer than ten (10) days).

SECTION 8.02. TZ Canada Circular

(a) TZ Canada shall, as soon as reasonably practicable, apply under the CBCA for an order of the Court approving the Arrangement and, in connection with such application, TZ Canada shall file and diligently prosecute an application for an Interim Order providing for the calling and holding of the TZ Canada Shareholders Meeting for the purpose of considering, and if deemed advisable, approving the Plan of Arrangement. The application shall request that the Interim Order provide (i) for the class of Persons to whom notice is to be provided in respect of the Plan of Arrangement and the TZ Canada Shareholders Meeting and for the manner in which such notice is to be provided, (ii) that the requisite approval for the TZ Canada Transaction Resolution shall be 66 2/3 % of the votes cast on the TZ Canada Transaction Resolution by the TZ Canada Shareholders present in person or by proxy at the TZ Canada Shareholders Meeting, (iii) that, in all other respects, the terms, restrictions and conditions of the By-laws and Articles of TZ Canada, including quorum requirements and all other matters, shall apply in respect of the TZ Canada Shareholders Meeting, and (iv) for the grant of the TZ Canada Dissent Rights.

Subject to the following sentence, (i) the TZ Canada Board shall recommend to the TZ Canada Shareholders that they approve the TZ Canada Transaction Resolution (the “TZ Canada Recommendation”) and include each recommendation in the TZ Canada circular, and (ii) TZ Canada will use its reasonable best efforts to solicit from the TZ Canada Shareholders proxies in favor of the approval of the TZ Canada Transaction Resolution and will use its reasonable best efforts to take all other action necessary or advisable to secure the TZ Canada Shareholder Approval. Notwithstanding the foregoing or anything in this Agreement to the contrary, the TZ Canada Board may determine (1) not to make or may withdraw, modify or change such recommendation (a “TZ Canada Change in Recommendation”), and (2) not to use such efforts to solicit proxies or take such other

-72-

necessary or advisable actions in favor of the approval of the TZ Canada Transaction Resolution if, in the case of both clauses (1) and (2), it has determined in good faith, after consultation with its outside legal counsel, that failure to take such action would be inconsistent with its fiduciary duties under applicable Canadian Law. Unless this Agreement has been terminated in accordance with Section 10.01, TZ Canada shall hold the TZ Canada Shareholders’ Meeting regardless whether the TZ Canada Board has made a TZ Canada Change in Recommendation. If there are an insufficient number of TZ Canada Shares represented in person or by proxy at the TZ Canada Shareholders’ Meeting to constitute a quorum or to adopt this Agreement, TZ Canada may adjourn or postpone, as applicable, the TZ Canada Shareholders’ Meeting for up to ten (10) business days so long as, during such period, TZ Canada uses its reasonable best efforts to obtain a quorum and the requisite vote to adopt this Agreement as promptly as practicable. TZ Canada may, if it receives an unsolicited TZ Canada Acquisition Proposal, delay the mailing of the TZ Canada Circular or the holding of the TZ Canada Shareholders Meeting, in each case for such reasonable period as would provide a reasonable opportunity for the TZ Canada Board to consider such TZ Canada Acquisition Proposal and to determine the effect, if any, on the TZ Canada Recommendation (but in any event not longer than ten (10) days).

(c) TZ Canada shall, subject to obtaining the approvals as are required by the Interim Order, use commercially reasonable efforts to diligently prosecute the application to the Court for the Final Order.

(d) As promptly as practicable following the date of this Agreement, TZ Canada shall prepare, in consultation with Parent, the TZ Canada Circular and Trizec and Parent shall prepare and file, in consultation with TZ Canada, any Additional Filings that are required to be made with any securities regulator in connection with the transactions contemplated hereby.

If applicable, each of Trizec, TZ Canada and Parent shall use its reasonable best efforts to respond as promptly as practicable to any comments of applicable securities regulators with respect to the TZ Canada Circular or the Additional Filings. TZ Canada shall promptly notify Trizec and Parent upon the receipt of any comments from any applicable securities regulator or its staff or any request from any applicable securities regulator or its staff for amendments or supplements to the TZ Canada Circular or the Additional Filings and shall promptly provide Trizec and Parent with copies of all correspondence between TZ Canada and its representatives, on the one hand, and the applicable securities regulator and its staff, on the other hand, relating to the TZ Canada Circular or the Additional Filings. If at any time prior to the TZ Canada Shareholders Meeting, any information relating to Trizec, TZ Canada or the Buyer Parties or any of their respective affiliates, officers, members or directors, should be discovered by Trizec, TZ Canada or Parent which should be set forth in an amendment or supplement to the TZ Canada Circular or the

-73-

Additional Filings, so that the TZ Canada Circular or the Additional Filings shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading, the party which discovers such information shall promptly notify the other parties, and an appropriate amendment or supplement describing such information shall be filed with the applicable securities regulator and, to the extent required by applicable Law, disseminated to the TZ Canada Shareholders. Notwithstanding anything to the contrary stated above, prior to filing or mailing the TZ Canada Circular or filing the Additional Filings (or any amendment or supplement thereto) or responding to any comments of an applicable securities regulator with respect thereto, TZ Canada shall provide Trizec and Parent a reasonable opportunity to review and comment on such document or response and will in good faith consider such comments, and to the extent practicable, TZ Canada will provide Trizec and Parent with the opportunity to participate in any substantive calls between TZ Canada, or any of its representatives, and the applicable securities regulator concerning the TZ Canada Circular.

Notwithstanding the foregoing, neither Parent nor any of its representatives shall (i) contact or have any discussions with any of the Trizec Parties’ or TZ Canada’s or either of their subsidiaries’ employees, agents, or representatives, unless in each case Parent obtains the prior written consent of the Trizec Parties or TZ Canada, as applicable, which shall not be unreasonably withheld, (ii) contact or have any discussions with any of the landlords/sub landlords, tenants/subtenants, or licensees or franchisees of the Trizec Parties and TZ Canada or their respective subsidiaries, unless in each case Parent obtains the prior written consent of the Trizec Parties or TZ Canada, as applicable, which shall not be unreasonably withheld, (iii) damage any property or any portion thereof, or (iv) perform any onsite procedure or investigation (including any onsite environmental investigation or study) without the Trizec Parties’ or TZ Canada’s, as applicable, prior written consent.

-74-

Business Day prior to the date that any tenant of a Trizec Property which Parent wishes to inspect is entitled to receive notice of any such inspection under the applicable Trizec Lease. The Trizec Parties and TZ Canada shall be entitled to have representatives present at all times during any such inspection. Notwithstanding the foregoing, neither the Trizec Parties and TZ Canada nor any of their respective subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would jeopardize the attorney-client privilege of the Trizec Parties or TZ Canada or any of their respective subsidiaries or contravene any Law or binding agreement entered into prior to the date of this Agreement.

(b) Prior to the Trizec Merger Effective Time, all information obtained by Parent pursuant to this Section 8.03 shall be kept confidential in accordance with the confidentiality agreement dated May 15, 2006 between Brookfield Properties Corporation, Trizec and TZ Canada (the “Confidentiality Agreement”).

SECTION 8.04. No Solicitation of Transactions by Trizec Parties.

(a) During the term of this Agreement, none of the Trizec Parties, any Trizec Subsidiary, TZ Canada or any TZ Canada Subsidiary shall, nor shall it authorize or knowingly permit, directly or indirectly, any officer, trustee, director, employee, investment banker, financial advisor, attorney, broker, finder or other agent, representative or affiliate (each, a “Representative”) of the Trizec Parties, any Trizec Subsidiary, TZ Canada or any TZ Canada Subsidiary to, (x) initiate, solicit, knowingly encourage or knowingly facilitate (including by way of furnishing nonpublic information or assistance) any inquiries or the making of any proposal or other action that constitutes, or may reasonably be expected to lead to, any Trizec Acquisition Proposal, (y) enter into discussions or negotiate with any Person in furtherance of such inquiries or to obtain a Trizec Acquisition Proposal, or (z) enter into any agreement in principle, contract or agreement (other than a confidentiality agreement entered into in accordance with the provisions of this Section 8.04) with respect to a Trizec Acquisition Proposal. Notwithstanding the foregoing or any other provision of this Agreement to the contrary, at any time prior to the receipt of the Trizec Stockholder Approval, following the receipt by the Trizec Parties or any Trizec Subsidiary of a bona fide written Trizec Acquisition Proposal (that was not solicited, encouraged or facilitated in violation of, or did not otherwise result from a breach of, this Section 8.04(a)), the Trizec Board or the Special Committee may (directly or through Representatives) (i) contact such Person and its advisors solely for the purpose of clarifying the proposal and any material terms thereof and the conditions to and likelihood of consummation, so as to determine whether such proposal is, or is reasonably likely to lead to, a Trizec Superior Proposal and (ii) if (x) the Trizec Board or the Special Committee determines in good faith after consultation with its outside legal and financial advisors that such Trizec Acquisition Proposal is, or is reasonably likely to lead to, a Trizec Superior Proposal and (y) the Trizec Board or the Special Committee determines in good faith, after consultation with its outside legal counsel, that failure to take such action would be inconsistent with its fiduciary duties under applicable Law, the Trizec Board or the Special Committee may (A) furnish non-

-75-

(b) The Trizec Parties shall take, and shall cause the Trizec Subsidiaries to take, all actions reasonably necessary to cause their respective Representatives to immediately cease any discussions, negotiations or communications with any party or parties with respect to any Trizec Acquisition Proposal; provided, however, that nothing in this Section 8.04 shall preclude Trizec, any Trizec Subsidiary or their respective Representatives from contacting any such party or parties solely for the purpose of complying with the provisions of the last sentence of this Section 8.04(b). Trizec, the Trizec Subsidiaries and TZ Canada shall promptly request each Person that has heretofore executed a confidentiality agreement in connection with its consideration of a Trizec Acquisition Proposal, if any, to return or destroy all confidential information heretofore furnished to such person by or on behalf of Trizec, the Trizec Subsidiaries and TZ Canada.

None of TZ Canada, Trizec or any Trizec Subsidiary shall, and such parties shall not permit any of their subsidiaries to, terminate, waive, amend or modify any provision of any existing standstill or confidentiality agreement to which TZ Canada, Trizec or any Trizec Subsidiary is a party and TZ Canada, Trizec or any Trizec Subsidiary shall, and shall cause each of their Subsidiaries to, enforce the provisions of any such agreement.

(d) Nothing in this Section 8.04 or elsewhere in this Agreement shall prevent the Trizec Board or the Special Committee from disclosing any information required to be disclosed under applicable Law or from complying with Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act with respect to a Trizec Acquisition Proposal; provided, however, that neither Trizec nor the Trizec Board shall be permitted to recommend that the Trizec Stockholders tender any securities in connection with any tender or exchange offer (or otherwise approve, endorse or recommend any Trizec Acquisition Proposal) or withdraw or modify the Trizec Recommendation, unless in each case, to the extent applicable, the requirements

-76-

of Sections 8.01(b) and 8.04(a) have been satisfied. In addition, nothing in this Section 8.04 or this Agreement shall prohibit Trizec Parties from taking any action that any court of competent jurisdiction orders Trizec Parties to take.

(e) Trizec shall not take any action to exempt any Person from the restrictions contained in Article IV of the Trizec Charter or otherwise cause any of such restrictions not to apply unless such actions are taken in connection with a termination of this Agreement in accordance with Section 10.01(h).

SECTION 8.05. No Solicitation of Transactions by TZ Canada.

(a) During the term of this Agreement, none of TZ Canada or any TZ Canada Subsidiary shall, nor shall it authorize or knowingly permit, directly or indirectly, any Representative of the Trizec Parties, any Trizec Subsidiary, TZ Canada or any TZ Canada Subsidiary to, (x) initiate, solicit, knowingly encourage or knowingly facilitate (including by way of furnishing nonpublic information or assistance) any inquiries or the making of any proposal or other action that constitutes, or may reasonably be expected to lead to, any TZ Canada Acquisition Proposal, (y) enter into discussions or negotiate with any Person in furtherance of such inquiries or to obtain a TZ Canada Acquisition Proposal, or (z) enter into any agreement in principle, contract or agreement (other than a confidentiality agreement entered into in accordance with the provisions of this Section 8.05) with respect to a TZ Canada Acquisition Proposal.

Each Continuing Employee will be credited with his or her years of service with TZ

-80-

Canada and the TZ Canada Subsidiaries (and any predecessor entities thereof) before the Closing Date under the parallel employee benefit plan of Parent or the TZ Canada Subsidiaries to the same extent as such employee was entitled, before the Plan of Arrangement Effective Time, to credit for such service under the respective Plan (except to the extent such credit would result in the duplication of benefits and except with respect to benefit accrual under a defined benefit plan).

The parties hereto agree that no public release or announcement concerning the transactions contemplated by this Agreement or the Mergers or the Arrangement shall be issued by a party without the prior consent of the other parties (which consent shall not be unreasonably withheld), except as such release or announcement may be required by Law, Canadian Law or the rules or regulations of any securities exchange, in which case the party required to make the release or announcement shall use its reasonable efforts to allow the other parties reasonable time to comment on such release or announcement in advance of such issuance. The parties have agreed upon the form of a joint press release announcing the Mergers, the Arrangement and the execution of this Agreement.

TZ Canada, Trizec and the Operating Company agree to cooperate in good faith and use their reasonable best efforts to take all actions necessary or advisable to effect the foregoing.

(d) by Parent if each of it and MergerCo and AcquisitionCo is not in material breach of its obligations under this Agreement, and if (i) any of the representations and warranties of the Trizec Parties or TZ Canada, as applicable, herein are or become untrue or incorrect such that the condition set forth in Section 9.02(a) would be incapable of being satisfied by the Outside Date, or (ii) there has been a breach on the part of the Trizec Parties or TZ Canada, as applicable, of any of their respective covenants or agreements herein such that the condition set forth in Section 9.02(b) would be incapable of being satisfied by the Outside Date;

-94-

such tender or exchange offer), or (4) Trizec or the Trizec Board publicly announces its intention to do any of the foregoing; or

(ii) by Parent if the TZ Canada Board shall have (1) effected a TZ Canada Change in Recommendation, (2) publicly recommended or approved any TZ Canada Acquisition Proposal, (3) a tender offer or exchange offer relating to the TZ Canada Shares that constitutes a TZ Canada Acquisition Proposal shall have been commenced by a Third Party and the TZ Canada Board shall not have recommended that the TZ Canada Shareholders reject such tender or exchange offer within ten (10) business days following commencement thereof (including, for these purposes, by taking no position with respect to the acceptance of such tender or exchange offer by the TZ Canada Shareholders, which shall constitute a failure to recommend acceptance of such tender or exchange offer), or (4) TZ Canada or the TZ Canada Board publicly announces its intention to do any of the foregoing; or

(h) by the Trizec Parties and TZ Canada, if the Trizec Board or Special Committee and the TZ Canada Board have approved, or authorized Trizec and TZ Canada, respectively, to enter into a definitive agreement or agreements with respect to, a Combined Superior Proposal, but only so long as:

(i) the Trizec Stockholder Approval and the TZ Canada Shareholder Approval has not yet been obtained;

(ii) Trizec and TZ Canada shall have first given Parent at least three (3) Business Days notice of their intent to terminate pursuant to this subsection (including in such notice the most current version of such agreement or agreements and any amendments thereto);

(ii) no Trizec Party nor TZ Canada is then in breach (and has not at any time been in breach) of any of its respective obligations under Sections 8.04 and 8.05 in any material respect;

(iii) during the three (3) Business Day period following Parent’s receipt of such notice, (A) Trizec shall have offered to negotiate with (and, if accepted, negotiated in good faith with), and shall have caused its respective financial and legal advisors to offer to negotiate with (and, if accepted, negotiated in good faith with), Parent in making adjustments to the terms and conditions of this Agreement as would enable Trizec to proceed with the Merger, and (B) the Trizec Board or Special Committee shall have determined in good faith, after the end of such three Business Day period, after considering the results of such negotiations and any amendment to this Agreement entered into, or for which Parent irrevocably covenants to enter into, within such three (3) Business Day period and for which all internal approvals of Parent have been obtained, such Trizec Superior Proposal continues to constitute a Trizec Superior Proposal; and

(iv) during the three (3) Business Day period following Parent’s receipt of such notice, (A) TZ Canada shall have offered to negotiate with (and, if accepted, negotiated in good faith with), and shall have caused its respective financial and legal advisors to

(v) the Trizec Parties pay to Parent the Full Termination Fee in accordance with Section 10.03(b)(iii) and the Parent Expenses concurrently with or prior to such termination (any purported termination pursuant to this Section 10.01(h) shall be void and of no force or effect unless the Trizec Parties shall have made such payment).

The party desiring to terminate this Agreement shall give written notice of such termination to the other parties.

The right of any party hereto to terminate this Agreement pursuant to this Section 10.01(a) shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any party hereto, any Person controlling any such party or any of their respective Representatives, whether prior to or after the execution of this Agreement.

In the event of the termination of this Agreement pursuant to Section 10.01, this Agreement shall forthwith become void, and there shall be no liability under this Agreement on the part of any party hereto except that the provisions of Sections 2.07, 8.03(b), 8.09(b), this Section 10.02, Section 10.03 and Article X shall survive any such termination; provided, however, that nothing herein shall relieve any party hereto from liability for any breach of any of its representations, warranties, covenants or agreements set forth in this Agreement prior to such termination.

period following the Termination Date Trizec enters into a contract with respect to or consummates a Trizec Acquisition Proposal, if and when such contract is entered into or consummation of such Trizec Acquisition Proposal occurs, as applicable, then Trizec shall pay to Parent on such consummation date the Trizec Termination Fee and the remaining 62% of the Parent Expenses in immediately available funds to an account directed by Parent (and for purposes of this Section 10.03(b)(ii), “50%” shall be substituted for “20%” in the definition of Trizec Acquisition Proposal);

(iii) “Parent Expenses” shall mean all reasonable out-of-pocket costs and expenses incurred by or on behalf of Parent (or its affiliates or investors) in connection with the entering into of this Agreement and the carrying out of any and all acts contemplated hereunder, including, without limitation, financing costs and the reasonable fees and expenses of lawyers, accountants, consultants, financial advisors, and investment bankers, up to an aggregate maximum amount of $25,000,000.

The payment of expenses by Parent set forth in this Section 10.03(e) or by TZ Canada or Trizec set forth in Section 10.03(b) is not an exclusive remedy, but is in addition to any other rights or remedies available to the parties hereto (whether at law or in equity), and in no respect is intended by the parties hereto to constitute liquidated damages, or be viewed as an indicator of the damages payable, or in any other respect limit or restrict damages available in case of any breach of this Agreement.

(e) Each of the Trizec Parties, TZ Canada and Parent acknowledges that the agreements contained in this Section 10.03 are an integral part of the transactions contemplated by this Agreement. In the event that (w) Trizec shall

-98-

fail to pay when due the Full Termination Fee and Parent Expenses pursuant to Section 10.03(b)(i), (iii) or (iv), (x) Trizec shall fail to pay when due the Trizec Termination Fee pursuant to the proviso in 10.03(b)(ii), (v) or (vi), (y) TZ Canada shall fail to pay when due the TZ Canada Termination Fee and Parent Expenses pursuant to Section 10.03(b)(ii), (v) or (vii) or (z) Parent shall fail to pay the Seller Party Expenses when due pursuant to Section 10.03(d), the Trizec Parties and TZ Canada or Parent, as the case may be, shall reimburse the other party for all reasonable costs and expenses actually incurred or accrued by such other party (including reasonable fees and expenses of counsel) in connection with the collection under and enforcement of this Section 10.03. If payable, none of the Full Termination Fee, Trizec Termination Fee, TZ Canada Termination Fee, Seller Party Expenses or Parent Expenses shall be payable more than once pursuant to this Agreement. For the avoidance of doubt, the parties hereto acknowledge that the maximum aggregate amount that may be paid pursuant to Section 10.03 by Trizec and TZ Canada shall be an amount equal to the Full Termination Fee plus the Parent Expenses.

SECTION 10.04. Escrow of Trizec Expenses.

(a) In the event that Parent is obligated to pay Trizec Expenses set forth in Section 10.03(e), Parent shall pay to Trizec from Trizec Expenses deposited into escrow in accordance with the next sentence, an amount equal to the lesser of (i) Trizec Expenses and (ii) the sum of (A) the maximum amount that can be paid to Trizec without causing Trizec to fail to meet the requirements of Sections 856(c)(2) and 856(c)(3) of the Code determined as if the payment of such amount did not constitute income described in Sections 856(c)(2)(A)-(H) or 856(c)(3)(A)-(I) of the Code (“Qualifying Income”), as determined by Trizec’s independent certified public accountants, plus (B) in the event Trizec receives either (1) a letter from Trizec’s counsel indicating that Trizec has received a ruling from the IRS described in Section 10.04(b) or (2) an opinion from Trizec’s outside counsel as described in Section 10.04(b), an amount equal to Trizec Expenses less the amount payable under clause (A) above. To secure Parent’s obligation to pay these amounts, Parent shall deposit into escrow an amount in cash equal to Trizec Expenses with an escrow agent selected by Parent and on such terms (subject to Section 10.04(b)) as shall be mutually agreed upon by Trizec, Parent and the escrow agent. The payment or deposit into escrow of Trizec Expenses pursuant to this Section 10.04(b) shall be made at the time Parent is obligated to pay Trizec such amount pursuant to Section 10.03(e) by wire transfer or bank check.

(b) The escrow agreement shall provide that Trizec Expenses in escrow or any portion thereof shall not be released to Trizec unless the escrow agent receives any one or combination of the following: (i) a letter from Trizec’s independent certified public accountants indicating the maximum amount that can be paid by the escrow agent to Trizec without causing Trizec to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code determined as if the payment of such amount did not constitute Qualifying Income or a subsequent letter from Trizec’s accountants revising that amount, in which case the escrow agent shall release such

-99-

amount to Trizec, or (ii) a letter from Trizec’s counsel indicating that Trizec received a ruling from the IRS holding that Trizec Expenses would either constitute Qualifying Income or would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code (or alternatively, Trizec’s outside counsel has rendered a legal opinion to the effect that the receipt by Trizec of Trizec Expenses would constitute Qualifying Income, would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code or would not otherwise disqualify Trizec as a REIT), in which case the escrow agent shall release the remainder of Trizec Expenses to Trizec. Parent agrees to amend this Section 9.04 at the request of Trizec in order to (x) maximize the portion of Trizec Expenses that may be distributed to Trizec hereunder without causing Trizec to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code, (y) improve Trizec’s chances of securing a favorable ruling described in this Section 10.04(b) or (z) assist Parent in obtaining a favorable legal opinion from its outside counsel as described in this Section 10.04(b). The escrow agreement shall also provide that any portion of Trizec Expenses held in escrow for five (5) years shall be released by the escrow agent to Parent.

SECTION 10.05. Waiver.

At any time prior to the Trizec Merger Effective Time, the Trizec Parties and TZ Canada (jointly), on the one hand, and Parent, MergerCo and AcquisitionCo, on the other hand, may (a) extend the time for the performance of any obligation or other act of the other party, (b) waive any inaccuracy in the representations and warranties of the other party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any agreement of the other party or any condition to its own obligations contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the Trizec Parties and TZ Canada (jointly) or Parent (on behalf of Parent, MergerCo and AcquisitionCo). The failure of any party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.

Each of the parties hereto agrees, (a) to the extent such party is not otherwise subject to service of process in the State of Delaware, to appoint and maintain an agent in the State of Delaware as such party’s agent for acceptance of legal process, and (b) that service of process may also be made on such party by prepaid certified mail with a proof of mailing receipt validated by the United States Postal Service constituting evidence of valid service. Service made pursuant to (a) or (b) above shall have the same legal force and effect as if served upon such party personally within the State of Delaware. For purposes of implementing the parties’ agreement to appoint and maintain an agent for service of process in the State of Delaware, Parent does hereby appoint The Prentice-Hall Corporation System, Inc. as such agent, Trizec does hereby appoint The Prentice-Hall Corporation System, Inc. as such agent and TZ Canada does hereby appoint The Prentice-Hall Corporation System, Inc. as such agent.

This Agreement may be executed and delivered (including by facsimile transmission) in two or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

SECTION 11.14. Waiver.

Except as provided in this Agreement, no action taken pursuant to this Agreement, including, without limitation, any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any

-104-

representations, warranties, covenants or agreements contained in this Agreement. The waiver by any party hereto of a breach of any provision hereunder shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder.

Delivery of Arrangement Consideration

(a) Prior to the Effective Time on the Effective Date, AcquisitionCo shall have deposited cash in immediately available funds (at Toronto) with the Depositary, for the benefit of each Shareholder (other than Dissenting Shareholders) in an amount sufficient to pay all Arrangement Consideration.

(b) Upon surrender to the Depositary of a certificate which immediately prior to the Effective Time represented one or more SVS or MVS together with a duly completed and

-6-

executed Letter of Transmittal and such other documents as AcquisitionCo or the Depositary may reasonably require, the holder of such surrendered certificate(s) shall be entitled to receive in exchange therefor, and the Depositary shall deliver to such holder the Arrangement Consideration that such holder has the right to receive pursuant to Section 2.2(d) by way of a cheque issued by the Depositary (or other form of immediately available funds), less any amounts withheld pursuant to Section 3.4.

(c) In the event of a transfer of ownership of SVS or MVS that is not registered in the transfer records of the Corporation, a cheque representing the proper amount of Arrangement Consideration (or other form of immediately available funds) may be delivered to the transferee if the certificate(s) representing such SVS or MVS is surrendered to the Depositary, accompanied by a duly completed and executed Letter of Transmittal and all documents required to evidence and effect such transfer.

(d) Until surrendered as contemplated by this Section 3.1, each certificate representing SVS (other than SVS held by Dissenting Shareholders) or MVS shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender a cash payment in the proper amount as contemplated by this Section 3.1, less any amounts withheld pursuant to Section 3.4.

(e) The cash deposited by AcquisitionCo with the Depositary with respect to the Arrangement Consideration shall be held in an interest bearing account, and any interest upon such funds shall be for the account of AcquisitionCo.
