The combined businesses will operate Canada's only nationwide GSM/GPRS/EDGE wireless network and will serve over 5.1 million voice and data customers. This transaction also creates a company of measurably increased scale allowing for significant opportunities for operating and capital spending efficiencies.
The members of the Board of Directors of Microcell have agreed that the Rogers Wireless offer is fair to the shareholders of Microcell and in the best interests of their company. The Board of Directors of Microcell has agreed to recommend to its shareholders to support the Rogers Wireless offer. The Board of Directors received opinions from its financial advisors, JP Morgan Securities Inc. and Rothschild that the Rogers Wireless offer is fair, from a financial point of view, to the shareholders of Microcell.
Rogers Wireless intends to finance the purchase through cash on hand, drawdown of its C$700 million bank credit facility and through bridge loan of up to C$900 million from RCI. RCI will fund the bridge loan through cash on hand and drawdown of credit facilities at its other subsidiaries.
The Rogers Wireless offer is subject to receipt of certain regulatory approvals and other customary conditions, including a requirement that two- thirds of the shares must be tendered.

prior to the Effective Date, the Corporation shall, and shall cause each of the Subsidiaries to, take such actions as are necessary or desirable to reorganize their respective capital, assets and corporate structure as the Offeror may reasonably require; provided, however, that no such reorganization will be undertaken if (i) the Offeror has not agreed to pay the reasonable actual out-of-pocket costs and expenses for filing fees and external counsel and auditors which may be incurred directly relating to same in the event that the Effective Date does not occur, (ii) the effectiveness thereof shall only occur immediately prior to the Offeror taking up the Securities under the Offers and (iii) any such actions shall not constitute a breach of the covenants, representations and warranties hereunder;

it shall advise the Offeror in writing promptly after any senior officer acquires actual knowledge thereof:

(A) of any event occurring subsequent to the date of this Agreement that would render any representation or warranty of the Corporation contained in this Agreement, if made on or as of the date of such event or the Effective Date, untrue, inaccurate or incomplete in any material respect (for any representation or warranty which expressly speaks solely of a specific date, if it would have been untrue, inaccurate or incomplete in respect of such date);

(B) of the occurrence of any event that has a Material Adverse Effect;

(D) of any death, disability, resignation, termination of employment or other departure of any senior officer of the Corporation or of any Subsidiary.

4.2 Covenants Relating to the Transaction

The Corporation hereby agrees that unless the Offers have been withdrawn in accordance with the terms hereof or this Agreement is terminated pursuant to Section 8:

if the Offeror takes up and pays for Securities pursuant to the Offers, it will assist the Offeror in connection with any Compulsory Acquisition or Subsequent Acquisition Transaction to acquire the remaining Securities, provided that the consideration offered in connection with the Subsequent Acquisition Transaction for each class of Securities is at least equal to the consideration offered under the Offers;

subject to obtaining an irrevocable and complete discharge in favour of each member of the Board and confirmation that insurance coverage is maintained as contemplated in Section 6.3 and provided that the Offeror has taken up and paid for at least two-thirds of the outstanding Shares, it shall use its reasonable commercial efforts to cause such members of the Board to resign as the Offeror may require, at the time and in the manner requested by the Offeror, as of the Effective Date, with a nominee of the Offeror to be appointed to the Board immediately after each such resignation. In the event that less than two-thirds of the outstanding Shares but more than 50.1% of the outstanding Shares on a fully diluted basis are taken up and paid for by the Offeror, the Corporation shall use its reasonable commercial efforts to cause a majority of the members of the Board to resign, with a nominee of the Offeror to be appointed immediately after each such resignation, the whole as provided above;

it shall recommend that holders of Shares accept the Offers in respect of the Shares and not act, or fail to act, in any way that might reasonably be expected to discourage such holders from accepting the Offers and, except as permitted hereby, not withdraw such recommendation;

it shall use all reasonable efforts to cause each holder of Options, entitlements under the Stock Option Plan, COM Canada Warrants or Warrants to exercise same (including, as regards Options or such entitlements, through application of acceleration of vesting) or to surrender same for cash or Shares in accordance with the terms thereof; provided that in connection with any acceleration of the vesting of Options caused by the Corporation for such purpose, the original vesting thereof shall revert six months after the Effective Date in respect of any such Options that remains outstanding;

it shall apply for and use all reasonable efforts to obtain or assist the Offeror in obtaining, as the case may be, all required regulatory and other approvals and clearances, including those identified in Schedule B, other than Competition Act Clearance, relating to the Corporation and the Subsidiaries and make all necessary filings and notifications in order to permit the transactions contemplated hereby to proceed together with all consents and other approvals of third parties as may be necessary or desirable for the consummation of such transactions;

it shall use all reasonable efforts to assist the Offeror in securing Competition Act Clearance, including but not limited to: (i) promptly filing all required notification(s) under Part IX of the Competition Act;

(ii) promptly co-operating with and providing all necessary information and documentation reasonably required by the Commissioner of Competition or her authorized representative upon being requested to do so by such authority; and Notwithstanding the foregoing, all requests and enquiries from the Commissioner of Competition or her authorized representative shall be dealt with by the Corporation in consultation with the Offeror. Furthermore, the Corporation shall: (A) not extend or consent to any extension of any waiting period under the Competition Act or enter into any agreement with the Commissioner of Competition or her authorized representative relating to the Offers to not consummate the transactions contemplated hereby, except with the consent of the Offeror;

(B) promptly notify the Offeror of written communications of any nature from the Commissioner of Competition relating to the Offers and provide the Offeror with copies thereof, except to the extent of any Highly Confidential Information (as defined in the Confidentiality Agreement), which Highly Confidential Information shall be provided only to the external legal counsel of the Offeror and shall not be shared by such counsel with any other person;

(C) permit the Offeror to review in advance any proposed written communications of any nature with the Commissioner of Competition or her authorized representative relating to the Offers, and provide the Offeror with final copies thereof, except to the extent of any Highly Confidential Information (as defined in the Confidentiality Agreement), which Highly Confidential Information shall be provided only to the external legal counsel of the Offeror and shall not be shared by such counsel with any other Person; and

(D) not participate in any substantive meeting or discussion (whether in person, by telephone or otherwise) with the Commissioner of Competition or her authorized representative relating to the Offers in respect of any filings, investigation or inquiry concerning the Offers unless it consults with the Offeror in advance and gives the Offeror the opportunity to attend and participate thereat (except where the Commissioner of Competition or her authorized representative expressly requests that the Offeror should not be present at the meeting or discussion or part or parts of the meeting or discussion); and

it shall use all reasonable efforts to defend all lawsuits or other legal, regulatory or other proceedings challenging or affecting the property or assets of the Corporation or any of the Subsidiaries, and in co-operation with Offeror, this Agreement or the consummation of the transactions contemplated hereby.

4.3 Directors' Circular and List of Holders

The Corporation confirms to the Offeror and agrees that:

it shall use its best efforts to mail a directors' circular (which shall reflect the determination and recommendation referred to in Section 3.2(d)) simultaneously with the mailing of the Offers, as well as providing drafts thereof to the Offeror, in order to provide the Offeror with an opportunity to comment thereon (it being agreed that the final form and content of the directors' circular shall be determined by the Corporation acting reasonably and on a basis consistent with the terms hereof); and

it shall cause a list of holders of Securities prepared by the Corporation or the transfer agent(s) of the Corporation in accordance with section 50 of the CBCA and a list of holders of Options and any other rights, Warrants, COM Canada Warrants or convertible securities currently outstanding (with full particulars as to the purchase, exercise or conversion price and expiry date) prepared by the Corporation (as well as a security position listing from each depositary, including The Canadian Depository for Securities Limited) to be delivered to the Offeror within five Business Days after execution of this Agreement and supplemental lists setting out any changes thereto for each Business Day thereafter to be delivered forthwith to the Offeror, all such deliveries to be both in printed form and computer-readable format.

not, directly or indirectly, through any officer, director, employee, representative or agent of the Corporation or any of the Subsidiaries, to solicit, initiate or knowingly encourage or facilitate (including by way of furnishing information or entering into any form of agreement, arrangement or understanding) the initiation of any inquiries or proposals regarding an Acquisition Proposal, participate in any discussions or negotiations regarding any Acquisition Proposal, withdraw or modify in a manner adverse to the Offeror the approval of the Board of the transactions contemplated hereby, accept or approve or recommend any Acquisition Proposal or cause the Corporation to enter into any agreement related to any Acquisition Proposal;

immediately to cease and cause to be terminated any existing discussions or negotiations with any parties (other than the Offeror) with respect to any potential Acquisition Proposal;

not to release or permit the release of any third party from or waive any confidentiality, non-solicitation or standstill agreement to which such third party is a party; and

immediately to cease to provide any other party with access to information concerning the Corporation and the Subsidiaries and request, in accordance with the confidentiality agreement signed with such parties, the return or destruction of all confidential information provided to any third party that has entered into a confidentiality agreement with the Corporation relating to any potential Acquisition Proposal.

5. ACQUISITION PROPOSALS, CHANGES IN RECOMMENDATION, ETC.

5.1 Acquisition Proposals

The Corporation shall provide the Offeror with a copy of (i) any written notice from any person informing it that such person is considering making, or has made, an Acquisition Proposal or (ii) any Acquisition Proposal (or any amendment thereto), in each case as soon as practicable after it is received by the Corporation.

5.2 Access to Information

If the Corporation receives a written request for non-public information relating to the Corporation and/or the Subsidiaries or any of them in connection with an Acquisition Proposal or for access to the properties, books or records of the Corporation and/or the Subsidiaries or any of them from a person who shall have made or intends to make an Acquisition Proposal and the Board determines in good faith, after consultation with financial advisors and outside legal advisors that the failure to take such action would be inconsistent with the Board's fiduciary duties and that such proposal, if consummated, in accordance with its terms, is reasonably likely to result in a Superior Proposal, then:

the Corporation may, subject to entering into a confidentiality agreement containing a standstill provision substantially similar to that contained in the Confidentiality Agreement, provide such person with access to such information; and

subject to any restrictions in that regard contained in the Confidentiality Agreement, the Offeror will be provided with a list of or copies of the information and access to similar information as that provided to such person, except to the extent such information was already provided or made available to the Offeror.

5.3 Changes in Recommendation

If the Corporation receives an Acquisition Proposal, the Corporation may withdraw or modify in a manner adverse to the Offeror its approval or recommendation of the Offers or accept, approve, recommend or enter into any agreement in respect of an Acquisition Proposal (other than the confidentiality agreement referred to in Section 5.2(a)) on the basis that such an Acquisition Proposal would constitute a Superior Proposal if:

the Corporation has given notice to the Offeror of its intention to do so, which notice shall disclose the fees and expenses payable to the Corporation's financial advisors referred to in Section 3.2(m) in respect of the completion of such Acquisition Proposal together with, in the case of an Acquisition Proposal that includes non-cash consideration, the value or range of values attributed by the Board in good faith for such non-cash consideration after consultation with its financial advisors;

the Corporation has complied with this Section 5;

the Corporation is not in default under Section 4.1(e)(i)-(v), 4.2(c), 4.3 or 4.4 of this Agreement; and

five Business Days shall have elapsed from the later of (i) the date the Offeror received the notice referred to in Section 5.3(a) and (ii) the date the Offeror was provided with a copy of such Acquisition Proposal.

5.4 Right to Match

The Offeror may, but is not required to, during the five Business Day period provided for in Section 5.3(d), offer in writing to amend the terms of this Agreement and, if it does so, then the Board shall review any such offer in good faith, in consultation with its financial and outside legal advisors and, if the Board:

determines that the Acquisition Proposal would thereby cease to be a Superior Proposal, it will cause the Corporation to enter into an amendment to this Agreement reflecting the offer by the Offeror to amend the terms hereof; or

continues to believe that the Acquisition Proposal would nonetheless remain a Superior Proposal, provided that the Corporation has paid to the Offeror the Termination Fee in accordance with the terms of Section 9.2, it may cause the Corporation to reject the offer by the Offeror to amend the terms hereof and terminate this Agreement as provided in Section 8.2.

5.5 Amendments to Acquisition Proposals

For greater certainty, any amendment of an Acquisition Proposal shall constitute a new Acquisition Proposal for the purposes of this Section 5.

6. COVENANTS OF THE OFFEROR

6.1 Offers

Subject to the terms and conditions hereof, the Offeror hereby agrees to:

provide copies of drafts of the Offers to the Corporation and its advisors, in order to provide them with an opportunity to comment thereon (it being agreed that the final form and content of the Offers (except for those terms and conditions described in Schedule A hereto, which will form part of the Offers) shall be determined by the Offeror, consistent with the terms hereof);

apply for and use all reasonable efforts to obtain all required regulatory and other approvals and clearances, including those identified in Schedule B, other than Competition Act Clearance, and make all necessary filings and notifications in order to permit the transactions contemplated hereby to proceed together with all consents and other approvals of third parties as may be necessary or desirable for the consummation of such transactions;

subject to Section 7.2, use all reasonable efforts to secure Competition Act Clearance, including but not limited to: (i) promptly filing all required notification(s) under Part IX of the Competition Act; and

(B) permit the Corporation to review in advance any material proposed written communications with the Commissioner of Competition or her authorized representative, and provide the Corporation with final copies thereof, except in case (A) and (B) above, to the extent of any Highly Confidential Information (as defined in the Confidentiality Agreement), which Highly Confidential Information shall be provided only to the external legal counsel of the Corporation and shall not be shared by such counsel with any other person;

if all of the conditions of the Offers are either met or, if applicable, waived at or prior to the expiry of the Offers, the Offeror shall take up the Securities deposited under the Offers and pay for such Securities as soon as practicable after, and in any event within two Business Days of, the first date on which the Offeror is permitted to do so under applicable securities laws;

in the event that the Offeror increases the consideration per Security offered under the Offers (but, for greater certainty, excluding any greater consideration paid as a consequence of a Compulsory Acquisition Transaction), the Offeror will pay such increased consideration to each holder of Securities in respect of all Securities tendered, notwithstanding that such Securities have previously been taken up and paid for by the Offeror;

if it takes up and pays for Securities pursuant to the Offers, use all commercially reasonable efforts to acquire the remaining Securities, within a period not exceeding 120 days after the date of completion of the Offers, by way of Compulsory Acquisition or Subsequent Acquisition Transaction for a consideration equal to the consideration under the Offers for each class of Securities;

following the Effective Date, it will cause the Corporation to duly and timely perform its obligations pursuant to (i) the compensation policy of the Corporation in respect of its directors and (ii) the Corporation's employment arrangements with officers and employees; and

without limitation to any other provision hereof, use all reasonable efforts to defend all lawsuits or other legal, regulatory or other proceedings challenging or affecting this Agreement or the consummation of the transactions contemplated hereby.

6.2 Stock Option Plan and Retention Plan

The Offeror acknowledges and agrees that:

the Board may resolve to permit all persons holding Options, which by their terms are otherwise currently exercisable or not, to exercise such Options concurrent with the expiry of the Offers, including by causing the vesting thereof to be accelerated;

the Board may authorize the cancellation of Options concurrent with the expiry of the Offers in consideration for cash and/or Shares issued, in each case in lieu of the cash value thereof;

it shall agree with the Corporation to tendering arrangements in respect of the Offers in order to facilitate the conditional exercise of the Options and tender of the Shares to be issued as a result of such conditional exercise (including providing for the ability of holders of Options to tender their Options or to tender Shares on the basis of guaranteed deliveries);

(i) holders of Options will be permitted to tender Shares issuable thereunder and for such purpose to exercise their Options, conditional upon the Offeror taking up and paying for the Shares under the Offers, which Options shall be deemed to have been exercised concurrently with the take-up of Shares and (ii) all Shares that are to be issued pursuant to any such conditional exercise shall be accepted as validly tendered under the Offers, provided that the holders of such Options indicate that the Shares are tendered pursuant to the Offers and otherwise validly accept the Offers in accordance with their terms with respect to such Shares;

if certain holders of Options do not exercise and tender their Options as contemplated under Section 6.2(d), the Offeror shall offer to pay to such holders, in respect of each Share subject to an Option, the cash amount, if any, by which the purchase price for the Shares under the Offers exceeds the exercise price of such Option on the date of take-up of, and payment for, the Shares under the Offers, in exchange for the termination of their Options; and

(i) subject to obtaining the consent of the Offeror, such consent not to be unreasonably withheld, the Board may establish a new retention pool for the benefit of certain or all of its key employees and officers so as to retain them until the Effective Date and (ii) the Board is entitled on or before the Effective Date to prepay the amounts which may become payable pursuant to the Corporation's existing retention plan and existing employment arrangements with its officers and employees.

6.3 Directors' and Officers' Insurance and Indemnities

Without limiting the right of the Corporation to do so prior to the Effective Date, the Offeror hereby agrees to use its reasonable commercial efforts to secure directors' and officers' liability insurance coverage for the current and former directors and officers of the Corporation and the Subsidiaries on a six year "trailing" (or "run-off") basis. If a trailing policy is not available at a reasonable cost, then the Offeror agrees that for the entire period from the Effective Date until six years after the Effective Date, the Offeror will cause the Corporation or any successor to the Corporation to maintain the Corporation's current directors' and officers' liability insurance policy or Equivalent Insurance having in either case terms and conditions no less advantageous in any material respect to the directors and officers of the Corporation or the Subsidiaries (with respect to their acting as directors or officers thereof) than those contained in the policy in effect on the date hereof, for all current and former directors and officers of the Corporation or the Subsidiaries, covering claims made prior to or within six years after the Effective Date. Further, the Offeror agrees that, after the expiration of that six year period, if there is no cost in doing so, the Offeror shall use reasonable commercial efforts to cause such directors and officers to be covered under the Offeror's then existing directors' and officers' liability insurance policy.

From and after the Effective Date, the Offeror shall not do anything to prevent the Corporation from indemnifying and hold harmless and providing advancement of expenses to, all past and present directors and officers of the Corporation or the Subsidiaries to the extent such persons are lawfully entitled to indemnity from the Corporation or the Subsidiaries or have the right to advancement of expenses as of the date of this Agreement by the Corporation or the Subsidiaries pursuant to the Corporation's or Subsidiaries' by-laws and indemnity agreements, in existence immediately prior to the Effective Date, for acts or omissions occurring on or prior to the Effective Date (including acts or omissions occurring in connection with the approval of this Agreement and consummation of the transactions contemplated hereby). The Offeror will not (unless it assumes such obligations and gives written notice to the beneficiaries thereof to the extent it has their addresses) liquidate the Corporation or otherwise take any other action to materially adversely affect the ability of the Corporation to satisfy its indemnity obligations referred to herein.

The provisions of this Section 6.3 are intended to be for the benefit of, and will be enforceable by, each insured or indemnified party, his or her heirs and his or her legal representatives. Furthermore, the provisions of this Section 6.3 shall survive the termination of this Agreement as a result of the occurrence of the Effective Date.

6.4 Confidentiality Agreement

The Offeror hereby confirms that it remains bound by the terms of the Confidentiality Agreement in accordance with the terms thereof, except to the extent modified hereby and notwithstanding that this Agreement may be terminated for any reason whatsoever.

7. FURTHER ASSURANCES

Each of the parties hereto, where appropriate, shall reasonably co-operate with the other in taking such actions.

if the Commissioner of Competition advises the Offeror that she has concerns about the competitive impact of the transactions contemplated by the Offers and this Agreement, and that Competition Act Clearance will be given if certain steps are taken to resolve those concerns, the Offeror shall take any steps necessary to secure Competition Act Clearance (including negotiating, offering to take and, if such offer is accepted, effecting by consent agreement or order, hold separate arrangement, undertaking or otherwise, the divestiture of assets, or undertaking of any form of behavioural remedy, however, not including the divestiture of all of the Securities or all or substantially all of the assets of the Corporation and its Subsidiaries), so as to enable the transactions contemplated by the Offers and this Agreement to be completed prior to the Outside Date; and

The Offeror agrees that the Termination Fee constitutes payment of liquidated damages which are a genuine anticipated assessment or estimate of the damages which it will suffer or incur as a result of the event giving rise to such damages and resulting in the termination of this Agreement and does not and will not constitute payment of a penalty.

No provision of this Agreement shall require the Corporation to cause any of its directors to take any action, or refrain from taking any action, that is required by such person to fulfill his/her fiduciary legal obligations as a director of the Corporation, nor, so long as the Corporation has not breached Section 4.1(e)(i)-(v), 4.2(c), 4.3, 4.4 or 5 of this Agreement, shall any provision of this Agreement prevent the Board from considering, negotiating, approving, recommending to its holders of Shares or other Securities or entering into an agreement in respect of a Superior Proposal or from approving or recommending such Superior Proposal. For greater certainty, a modification, change or withdrawal by the Board of its recommendation of the Offers after the date hereof in the proper exercise of such fiduciary duty shall not result in the representations in Section 3.2 of this Agreement being considered to be untrue or incorrect.

For greater certainty, the written agreement of those persons referred to in Section 6.3(c) shall not be required, except that no amendment to Section 6.3 or relating to a person's rights thereunder may be effected on or after the Effective Date without such person's written agreement.

11.8 Specific Performance and Other Relief

Accordingly, in the event of any such breach, any aggrieved party shall be entitled to the remedy of specific performance of such obligations and interlocutory, preliminary and permanent injunctive and other equitable relief in addition to any other remedy to which it or they may be entitled, at law or in equity, any requirement for the securing or posting of any bond in connection with the obtaining of any such injunctive or other equitable relief hereby being waived.
