AND

MANAGEMENT PROXY CIRCULAR

MAY 25, 2005


	It may be difficult for shareholders of Call-Net Enterprises Inc. who are resident in the United States to enforce their rights and any claim they may have arising under the United States federal securities laws, since Call-Net Enterprises Inc. and Rogers Communications Inc. are incorporated and organized under the laws of Canada and British Columbia, respectively, some or all of their respective officers and directors may be resident outside of the United States and all or a substantial portion of the assets of such persons are located outside the United States. Shareholders of Call-Net Enterprises Inc. who are resident in the United States may not be able to sue a Canadian company or its officers or directors in a Canadian court for violations of the United States securities laws. It may be difficult to compel a Canadian company and its affiliates to subject themselves to a United States court’s judgment.

Dear Shareholder,

It is my pleasure to extend to you, on behalf of the Board of Directors of Call-Net Enterprises Inc. (“Call-Net”), an invitation to attend a special meeting of the shareholders of Call-Net to be held at the Hilton Toronto (Toronto III Room), 145 Richmond Street West, Toronto, Ontario on Wednesday, June 29, 2005 at 11:00 a.m. (Toronto time).

At the meeting, you will be asked to consider and, if considered advisable, approve, a special resolution (the “Arrangement Resolution”) with respect to the arrangement (the “Arrangement”) involving the acquisition by Rogers Communications Inc. (“RCI”) of all of the outstanding common shares (the “Common Shares”) and all of the outstanding Class B non-voting shares (the “Non-Voting Shares” and, together with the Common Shares, the “Call-Net Shares”) of Call-Net, pursuant to an arrangement agreement made as of May 11, 2005 between Call-Net and RCI.

Under the Arrangement, shareholders will receive, for every 4.25 Call-Net Shares they hold, one Class B Non-Voting Share of RCI (“RCI Non-Voting Share”).

The attached Notice of Special Meeting and Management Proxy Circular (the “Circular”) outline in detail the actions to be taken by shareholders at the meeting. Please review the Circular carefully — it has been prepared to help you make an informed investment decision.

The Board of Directors has determined that holders of Non-Voting Shares will be entitled to vote at the Meeting together as a single class with holders of Common Shares on the basis of one vote for each share held.

The Board of Directors has determined that the Arrangement is fair to Call-Net’s shareholders and in the best interests of Call-Net and unanimously recommends that Call-Net’s shareholders vote in favour of the Arrangement. In arriving at this decision, the Board of Directors considered a number of factors including:


	1.	the exchange ratio of one RCI Non-Voting Share for every 4.25 Call-Net Shares, which, based upon the closing price on May 10, 2005 (the trading day immediately prior to the announcement of the Arrangement) of RCI Non-Voting Shares on the Toronto Stock Exchange of $37.00, represented a premium of approximately 34% and 33% over the closing price of the Common Shares and the Non-Voting Shares, respectively, on the Toronto Stock Exchange on May 10, 2005;

	2.	management believes that Call-Net’s growth strategy will be more easily achieved as a part of RCI than it would on a stand-alone basis;

	3.	the Arrangement will enable Call-Net’s shareholders to participate in the future prospects of RCI, including Call-Net;

	4.	RCI has a significantly larger market capitalization than Call-Net and the RCI Non-Voting Shares have greater liquidity than the Call-Net Shares;

	5.	current industry, economic and market conditions and trends;

	6.	historical market prices and trading information with respect to the Call-Net Shares and the RCI Non-Voting Shares;

	7.	information regarding the business, operations, property, assets, financial performance and condition, operating results and prospects of Call-Net and RCI;

	8.	the likelihood that the transactions contemplated in the Arrangement would be completed, given the conditions and regulatory approvals necessary to complete such transactions;

	9.	the fairness opinion of BMO Nesbitt Burns Inc., the financial advisor to Call-Net, which concluded that the consideration offered to holders of the Common Shares and holders of the Non-Voting Shares pursuant to the Arrangement is fair, from a financial point of view, to such shareholders;


	10.	the terms of the Arrangement Agreement, which permit the Board of Directors to consider and respond to a Superior Proposal (as defined in the Circular) subject to the payment of a termination fee to RCI in certain circumstances;

	11.	the requirement that the Arrangement Resolution be passed by at least two-thirds of the votes cast by Call-Net’s shareholders present in person at the special meeting or represented by proxy, with the holders of the Common Shares and the Non-Voting Shares voting as a single class, on the basis that they are being treated equally under the Arrangement and on the basis that they have substantially the same economic entitlements;

	12.	when the Arrangement becomes effective, the Call-Net Rights Plan will no longer be necessary to protect the interests of Call-Net shareholders;

	13.	the procedures by which the Arrangement is to be approved, including the requirement for approval by the Ontario Superior Court of Justice after a hearing at which fairness will be considered; and

	14.	the availability of rights of dissent to registered shareholders with respect to the Arrangement.

This Circular contains a detailed description of the Arrangement and other information relating to Call-Net and RCI. We urge you to consider carefully all of the information in the Circular. If you require assistance, please consult your financial, legal or other professional advisor.

If you are unable to be present at the meeting in person, we encourage you to vote by completing the applicable enclosed form of proxy. A holder of Common Shares should use the enclosed blue form of proxy, and a holder of Non-Voting Shares should use the enclosed green form of proxy. Voting by proxy will not prevent you from voting in person if you attend the meeting but will ensure that your vote will be counted if you are unable to attend. If you are a non-registered holder of shares and have received these materials through your broker or through another intermediary, please complete and return the proxy or other authorization provided to you by your broker or by such other intermediary in accordance with the instructions provided with the proxy. Failure to do so may result in your shares not being eligible to be voted at the meeting. This is an important matter affecting the future of your company and your vote is important regardless of the number of shares you own.

We also encourage you to complete and return the enclosed Letter of Transmittal (printed on yellow paper), together with the certificate(s) representing your Call-Net Shares to CIBC Mellon Trust Company (the “Depositary”) at the address specified in the Letter of Transmittal. The Letter of Transmittal contains other procedural information relating to the Arrangement and should be reviewed carefully. It is recommended that you complete, sign and return the Letters of Transmittal with accompanying Call-Net Share certificates to the Depositary as soon as possible, and preferably prior to 5:00 p.m. (Toronto time) on June 27, 2005.

Subject to obtaining court and other regulatory approvals, if shareholders of Call-Net approve the Arrangement, it is anticipated that the Arrangement will be completed in early July 2005.

On behalf of Call-Net, we would like to thank all shareholders for their ongoing support as we prepare to take part in this important event in the history of Call-Net.

Yours truly,

Lawrence G. Tapp

Chairman of the Board

CALL-NET ENTERPRISES INC.

	2.	each Call-Net Share (other than Call-Net Shares in respect of which the Shareholder has validly exercised his or her right of dissent) shall be deemed to be transferred to Call-Net Acquisition Company, in the case of Non-Taxable Holders, and to RCI, in the case of all other Shareholders, for RCI Non-Voting Shares on the basis of one RCI Non-Voting Share for every 4.25 Call-Net Shares;

	3.	each Call-Net Share in respect of which a Shareholder has validly exercised his or her right of dissent shall be deemed to be transferred to Call-Net for cancellation. See “Rights of Dissenting Shareholders”;

	4.	unless RCI otherwise notifies the Secretary of Call-Net in writing prior to the Effective Date, the Call-Net Preferred Share shall be deemed to be redeemed by Call-Net for $1.00, being the redemption price therefor;

	5.	each holder of Call-Net Options that are outstanding and unexercised immediately prior to the Effective Date shall receive options to acquire RCI Non-Voting Shares under the RCI Stock Option Plan in replacement for such Call-Net Options; and


	6.	with respect to any Call-Net PUs outstanding and unexercised immediately prior to the Effective Date (whether or not then vested), in no event shall they represent any entitlement to receive or otherwise acquire Call-Net Shares or to acquire RCI Non-Voting Shares, but otherwise the rights of a holder thereof shall be unaffected and each such holder shall be paid on the Effective Date the amount to which such holder is entitled in respect of such holder’s Call-Net PUs.

BMO NB Fairness Opinion

BMO NB was engaged by Call-Net to advise and assist Call-Net in considering certain strategic alternatives, including providing a fairness opinion to the Board of Directors, if requested. BMO NB has been engaged by Call-Net in an advisory capacity from time to time since December 2000. Call-Net requested that BMO NB provide an opinion to the Board of Directors of Call-Net as to the fairness, from a financial point of view, of the consideration offered to Shareholders pursuant to the Arrangement. BMO NB delivered its opinion orally to the Board of Directors on May 10, 2005. BMO NB subsequently confirmed its opinion by delivery of a written opinion to the Board of Directors, a copy of which is attached as Appendix E. Based upon and subject to the assumptions made and the matters considered in the BMO NB Fairness Opinion, BMO NB is of the opinion that the consideration offered to Shareholders pursuant to the Arrangement is fair, from a financial point of view, to the Shareholders. A copy of the BMO NB Fairness Opinion is attached to this Circular as Appendix E. Shareholders are urged to read such opinion in its entirety.

See “The Arrangement — BMO NB Fairness Opinion”.

Recommendation of the Board of Directors

The Board of Directors believes that the Arrangement is fair to Shareholders and in the best interests of Call-Net. Accordingly, the Board of Directors has unanimously approved the Arrangement and recommends that Shareholders vote in favour of the Arrangement Resolution.

Reasons for the Recommendation

The Board considered a number of factors in concluding that the Arrangement is in the best interests of Call-Net, including the following:


	1.	the exchange ratio of one RCI Non-Voting Share for every 4.25 Call-Net Shares which, based upon the closing price on May 10, 2005 (the trading day immediately prior to the announcement of the Arrangement) of RCI Non-Voting Shares on the TSX of $37.00, represented a premium of approximately 34% and 33% over the closing price of the Common Shares and the Non-Voting Shares, respectively, on the TSX on May 10, 2005;

	2.	management believes that Call-Net’s growth strategy will be more easily achieved as a part of RCI than it would on a stand-alone basis;

	3.	the Arrangement will enable the Shareholders to participate in the future prospects of RCI, including Call-Net;

	4.	RCI has a significantly larger market capitalization than Call-Net and the RCI Non-Voting Shares have greater liquidity than the Call-Net Shares;

	5.	current industry, economic and market conditions and trends;

	6.	historical market prices and trading information with respect to the Call-Net Shares and the RCI Non-Voting Shares;

	7.	information regarding the business, operations, property, assets, financial performance and condition, operating results and prospects of Call-Net and RCI;

	8.	the likelihood that the transactions contemplated in the Arrangement would be completed, given the conditions and regulatory approvals necessary to complete such transactions;

	9.	the BMO NB Fairness Opinion, which concluded that the consideration offered to Shareholders pursuant to the Arrangement is fair, from a financial point of view, to Shareholders;

	10.	the terms of the Arrangement Agreement, which permit the Board of Directors to consider and respond to a Superior Proposal subject to the payment of the Termination Fee to RCI in certain circumstances;

	11.	the requirement that the Arrangement Resolution be passed by at least two-thirds of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, with the holders of the Common Shares and the Non-Voting Shares voting as a single class, on the basis that they are being treated equally under the Arrangement and on the basis that they have substantially the same economic entitlements;

	12.	as at the Effective Time, the Call-Net Rights Plan will no longer be necessary to protect the interests of the Shareholders;

	13.	the procedures by which the Arrangement is to be approved, including the requirement for approval by the Court after a hearing at which fairness will be considered; and

	14.	the availability of rights of dissent to the registered Shareholders with respect to the Arrangement.

See “The Arrangement — Recommendation of the Board of Directors”.

Interests of Certain Persons in the Arrangement

In considering the recommendation of the Board of Directors with respect to the Arrangement, Shareholders should be aware that certain officers and directors of Call-Net have certain interests in the Arrangement, including those referred to in “The Arrangement — Interests of Certain Persons in the Arrangement”.

The Arrangement Agreement

The Arrangement Agreement provides for the Arrangement and matters related thereto. See “The Arrangement Agreement.”

Covenants Regarding Non-Solicitation

In the Arrangement Agreement, Call-Net has agreed not to, among other things, directly or indirectly solicit, initiate or knowingly encourage or facilitate 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 RCI the approval of the Board of Directors of the transactions contemplated by the Arrangement Agreement, or accept, approve or recommend any Acquisition Proposal or enter into any agreement related to any Acquisition Proposal. Call-Net has also agreed to cease all existing discussions or negotiations with any parties other than RCI with respect to any potential Acquisition Proposal.

In addition, Call-Net may not release any third party from or waive any confidentiality, non-solicitation or standstill agreement, must immediately cease to provide any other party with access to information concerning any of the Call-Net Entities and request the return or destruction of all confidential information that has been previously provided.

Notwithstanding the foregoing, nothing shall prevent the Board of Directors from complying with Call-Net’s disclosure obligations with respect to an unsolicited bona fide written Acquisition Proposal; considering, negotiating or discussing a Superior Proposal; or withdrawing or modifying its recommendation to vote in favour of the Arrangement, if the Board of Directors so determines that an Acquisition Proposal is a Superior Proposal under certain conditions.

Call-Net must immediately notify RCI of any Acquisition Proposal or any request for non-public information in connection with an Acquisition Proposal or access to the properties, books or records of any of the Call-Net Entities from any person that informs Call-Net that it is considering making an Acquisition Proposal. Call-Net may provide another person with material non-public information relating to the Call-Net Entities or any of them if it receives a request for such information from a Person who has made an unsolicited bona fide Acquisition Proposal, subject to the execution by such Person of a confidentiality agreement (which shall in no respect be more favourable to such Person than the terms of the confidentiality agreement between RCI and Call-Net), provided however, that the Person making the Acquisition Proposal shall not be precluded under such confidentiality agreement from making an Acquisition Proposal that is a Superior Proposal.

Notice of Superior Proposal Determination

Call-Net has agreed under the Arrangement Agreement not to accept, approve, recommend or enter into any agreement relating to an Acquisition Proposal (other than a confidentiality agreement) on the basis that it would constitute a Superior Proposal unless: (a) the Board of Directors has determined in good faith that the Acquisition Proposal constitutes a Superior Proposal; (b) Call-Net has provided RCI with a copy of the Acquisition Proposal document which the Board of Directors has determined would be a Superior Proposal; (c) five Business Days (the “Response Period”) have elapsed from the later of the date RCI receives notice of Call-Net’s proposed determination to accept, approve, recommend or enter into any agreement relating to such Acquisition Proposal, and the date RCI receives a copy of the Acquisition Proposal; and (d) Call-Net is not in any material respect (x) in default under the Arrangement Agreement or (y) in breach of any of its representations or warranties contained in the Arrangement Agreement.

Right to Match

During the Response Period, RCI may, but is not required to, offer in writing to amend the terms of the Arrangement Agreement and the Arrangement. If it does so, then the Board of Directors must review any such offer to amend the Arrangement Agreement in good faith in order to determine, in its discretion in the exercise of its fiduciary duties, whether the offer to amend the Arrangement Agreement would result, upon acceptance, in the Acquisition Proposal not being a Superior Proposal. If the Board of Directors so determines, Call-Net must enter into an amendment to the Arrangement Agreement reflecting RCI’s amended proposal. If the Board of Directors continues to believe, in good faith and after consultation with financial and outside legal advisors, that the Acquisition Proposal would nonetheless remain a Superior Proposal and therefore rejects RCI’s amended proposal, Call-Net may (a) terminate the Arrangement Agreement, subject to the payment of certain termination fees (see “Termination Fee” below); and (b) approve, recommend, accept or enter into an agreement, understanding or arrangement with respect to the Superior Proposal.

Conditions to the Arrangement

The implementation of the Arrangement is subject to certain conditions being satisfied or waived by one or both of Call-Net and RCI at or before the Effective Time, including, without limitation:

Regulatory Approvals

The obligations of Call-Net and RCI to complete the Arrangement are subject to the receipt of certain court and regulatory approvals on or before the Effective Date or such earlier time as is specified below, including the following:


	1.	The Interim Order must have been granted.

	2.	The Final Order must have been granted.

	3.	All required consents, orders, authorizations, approvals and waivers of Governmental Entities, including appropriate regulatory approvals and judicial approvals and orders required for the completion of the transactions contemplated by the Arrangement.

Shareholder Approval

The obligations of Call-Net and RCI to complete the Arrangement are subject to the Arrangement Resolution being passed at the Meeting, in accordance with the Interim Order. In particular, in order for the Arrangement to become effective, the Arrangement Resolution must be passed by at least two-thirds of the votes cast by the Shareholders present in person or by proxy at the Meeting.

Termination Fee

Call-Net will be required to pay to RCI the sum of $10 million in the event that the Board of Directors (i) withdraws or modifies in a manner adverse to RCI its approval or recommendation of the Arrangement and makes a public announcement to that effect, (ii) recommends any Superior Proposal and makes a public announcement to that effect, or (iii) fails to promptly reaffirm its recommendation of the Arrangement by press release in certain circumstances, provided in each case that RCI is not in default in the performance of its material obligations under the Arrangement Agreement.

In addition, if the Arrangement Agreement has been terminated without payment of the Termination Fee and in circumstances where RCI is not in breach of any of its representations, warranties, covenants or other agreements in any material respect and all approvals required under the Competition Act (Canada) have been obtained prior to the termination and, within four months, an Acquisition Proposal is consummated that has a value per Call-Net Share greater than the Call-Net Share value attributed to the Arrangement, Call-Net shall pay to RCI an amount equal to the Termination Fee.

Secured Notes After the Arrangement

Under the terms of the Indenture, within 30 days following the Effective Date, Call-Net will be required to commence an offer to purchase all of the outstanding Secured Notes at a purchase price of 101% of their principal amount plus accrued and unpaid interest and certain additional amounts in respect of any withholding taxes that may be levied on certain holders of the Secured Notes as a result of purchases made under the offer. If, as a result of such offer to purchase all of the outstanding Secured Notes, Call-Net purchases 66²/3% of the Secured Notes outstanding, the Indenture provides that Call-Net would have the right under the Indenture to redeem the remaining outstanding Secured Notes, in whole but not in part, at the same price. Under the terms of the Indenture, a third party (including RCI or one of its Subsidiaries) may make an offer to purchase the outstanding Secured Notes in lieu of Call-Net, provided that it makes such offer in the manner, at the times and otherwise in compliance with the requirements set forth in the Indenture applicable to any offer to purchase the outstanding Secured Notes made by Call-Net and provided further that it purchases all Secured Notes validly tendered and not withdrawn under its offer. The principal amount of the Secured Notes outstanding at the Effective Date is expected to be approximately US$223.1 million.

Unaudited Pro Forma Consolidated Financial Statements of RCI

The unaudited pro forma consolidated financial statements of RCI that give effect to the Arrangement are set forth in Appendix G to this Circular.

Court Approval and Completion of the Arrangement

Subject to the approval of the Arrangement Resolution by the Shareholders at the Meeting, the hearing in respect of the Final Order is currently scheduled to take place on July 7, 2005 at 10:00 a.m. (Toronto time) in the Court at 393 University Ave., Toronto, Ontario or as soon thereafter as is reasonably practicable. Any Shareholder who wishes to appear or be represented and to present evidence or arguments must serve and file a Notice of Appearance as set out in the Notice of Application for the Final Order and satisfy any other requirements of the Court. The Court will consider, among other things, the fairness and reasonableness of the Arrangement. The Court may approve the Arrangement in any manner the Court may direct, subject to compliance with such terms and conditions, if any, as the Court deems fit.

Assuming the Final Order is granted and the other conditions to closing contained in the Arrangement Agreement are satisfied or waived, it is currently anticipated that Articles of Arrangement for Call-Net will be filed with the Director under the CBCA to give effect to the Arrangement on or about July 8, 2005. See “The Arrangement — Court Approval and Completion of the Arrangement”.

Rights of Holders of Common Shares and Non-Voting Shares

The holders of Common Shares are entitled to one vote for each share held at any meeting of Shareholders. The holders of Non-Voting Shares are not entitled to vote at any meeting of Shareholders except for votes affecting the Non-Voting Shares. Pursuant to the Interim Order, holders of Common Shares and Non-Voting Shares will be entitled to vote, as a single class, on the Arrangement Resolution and such shares shall be entitled to one vote for each such share held at the Meeting.

Procedures for Exchange of Share Certificates by Shareholders

Enclosed with this Circular is a Letter of Transmittal (printed on yellow paper), which is being delivered to registered Shareholders. The Letter of Transmittal, when properly completed and duly executed and returned together with a certificate or certificates representing Call-Net Shares and all other required documents, will enable each Shareholder to obtain a certificate representing one whole RCI Non-Voting Share in exchange for every 4.25 Call-Net Shares previously held and represented by the deposited share certificate or certificates.

If you are a non-registered holder of Call-Net Shares and hold your Call-Net Shares through a broker or another intermediary, please complete the documentation provided to you by your broker or such other intermediary in accordance with the instructions provided by such intermediary. See “Procedures for Exchange of Share Certificates by Shareholders”.

Where a certificate for Call-Net Shares has been destroyed, lost or mutilated, the registered holder of that certificate should immediately contact CIBC Mellon, toll free at 1-800-387-0825, or in the Toronto area at (416) 643-5500, regarding the issuance of a replacement certificate upon the holder satisfying such requirements as may be imposed by Call-Net in connection with the issuance of the replacement certificate. It is recommended that Shareholders complete, sign and return the Letters of Transmittal with accompanying Call-Net Share certificates to the Depositary as soon as possible, and preferably prior to 5:00 p.m. (Toronto time) on June 27, 2005. See “Procedures for Exchange of Share Certificates by Shareholders”.

Fractional Shares

No fractional RCI Non-Voting Shares will be issued. In lieu of fractional RCI Non-Voting Shares, each Shareholder otherwise entitled to a fractional interest in an RCI Non-Voting Share will receive a cheque following the Effective Date in an amount equal to such fractional interest multiplied by $37.00.

Dissent Rights

Pursuant to the Interim Order, registered Shareholders have been granted the right to dissent in respect of the Arrangement. If the Arrangement becomes effective, a Dissenting Shareholder is entitled to be paid the fair value of such Dissenting Shareholder’s Call-Net Shares provided such Dissenting Shareholder has delivered a written objection to the Arrangement Resolution to Call-Net by 5:00 p.m. (Toronto time) on the second business day preceding the Meeting and the Dissenting Shareholder shall have otherwise complied with the dissent procedures described in this Circular including the relevant provisions of Section 190 of the CBCA. This right is described in detail under the heading “Rights of Dissenting Shareholders”; the text of Section 190 of the CBCA, which will be relevant in any dissent proceeding, is set forth in Appendix F to this Circular. Failure to comply strictly with the dissent procedures described in the Circular may result in the loss of any right of dissent.

Delisting of Call-Net Shares

If the Arrangement is completed, the Call-Net Shares will be de-listed from the TSX.

Certain Canadian Federal Income Tax Considerations

A Shareholder who is a resident of Canada for purposes of the ITA and who does not certify that he or she is a Non-Taxable Holder will tender his or her Shares to RCI. In such circumstances, the Shareholder will be deemed to have disposed of his or her Call-Net Shares for proceeds equal to the Shareholder’s adjusted cost base in respect of such shares and to have acquired the RCI Non-Voting Shares at a cost equal to such proceeds of disposition less the amount of any cash received by such holder in lieu of a fractional RCI Non-Voting Share, unless such Shareholder chooses to report any portion of the capital gain or capital loss arising on the exchange.

In general, a holder of Call-Net Shares who is not a resident of Canada for purposes of the ITA will not be subject to Canadian federal income tax on the disposition of Call-Net Shares under the Arrangement.

A Call-Net Shareholder who certifies that he or she is a Non-Taxable Holder, will tender his or her Shares to Call-Net Acquisition Company such that the cost for Canadian tax purposes of the Call-Net Shares acquired by Call-Net Acquisition Company will be equal to the fair market value of the RCI Non-Voting Shares issued in exchange for the Call-Net Shares. See “Material Canadian Federal Income Tax Considerations” in the Circular.

Certain United States Federal Income Tax Considerations

The exchange of Call-Net Shares for RCI Non-Voting Shares pursuant to the Plan of Arrangement will be a taxable disposition for United States Federal income tax purposes. In general, a United States holder of Call-Net Shares will recognize a gain or loss for United States Federal income tax purposes as a result of the Arrangement

in an amount equal to the difference between (i) such holder’s adjusted tax basis in its Call-Net Shares transferred in the Arrangement and (ii) the fair market value of the RCI Non-Voting Shares received in the Arrangement. See “Material United States Federal Income Tax Considerations”.

Neither

delivery of this Circular nor any distribution of the securities referred to in this Circular will, under any circumstances, create an implication that there has been no change in the information set forth herein since the date of this Circular.

NOTICE TO U.S. SHAREHOLDERS

Securities issued in the Arrangement will not be registered under the 1933 Act or the securities laws of any state of the United States. Such securities will instead be issued in reliance upon the exemption provided by Section 3(a)(10) of the 1933 Act and applicable exemptions under state securities laws. Securities issued under the Arrangement will be freely transferable under United States federal securities laws, except for securities held by persons who are deemed to be “affiliates” of Call-Net prior to the Effective Time or to be “affiliates” of RCI at the time of any resale of such securities. Such securities held by “affiliates” may be resold by them only in transactions permitted by the resale provisions of Rule 145(d) promulgated under the 1933 Act or as otherwise permitted under the 1933 Act. See “Regulatory Matters — Securities Law Matters — United States”.

The solicitation and transactions contemplated herein are made by Call-Net, a foreign issuer that has prepared this Circular in accordance with the disclosure requirements of Canada. Shareholders resident in the United States should be aware that such requirements are different from those applicable to proxy statements, prospectuses or registration statements prepared in accordance with U.S. laws, and that this Circular has not been filed with the SEC or the securities regulatory authority of any state within the United States. The financial statements included or incorporated by reference herein have been prepared in accordance with Canadian generally accepted accounting principles, and are subject to Canadian auditing and auditor independence standards and, thus, may not be comparable to financial statements of U.S. companies.

Shareholders resident in the United States should be aware that the Arrangement described herein may have tax consequences both in the United States and in Canada. Such consequences for Shareholders may not be described fully herein. For the Canadian income tax consequences to investors who are resident in the United States, see “Material Canadian Federal Income Tax Considerations — Non-Residents of Canada”. For the United States federal income tax consequences to investors who are resident in the United States, see “Material United States Federal Income Tax Considerations”. U.S. holders are urged to consult their own tax advisors with respect to such Canadian and United States federal and state income tax consequences.

The enforcement by investors of civil liabilities under the United States securities laws may be affected adversely by the fact that Call-Net and RCI are organized under the laws of jurisdictions other than the United States, that some or all of their respective officers and directors are residents of countries other than the United States, that some or all of the experts named in the Circular are residents of countries other than the United States, or that all or a substantial portion of the assets of Call-Net, RCI and such persons are located outside the United States. Shareholders may not be able to sue Call-Net or RCI or their respective directors and officers in a foreign court for violations of U.S. securities laws. It may be difficult to compel Call-Net, RCI or their respective affiliates to subject themselves to a U.S. court’s judgment.

THE RCI NON-VOTING SHARES ISSUABLE PURSUANT TO THE ARRANGEMENT HAVE NOT BEEN AND WILL NOT BE REGISTERED UNDER THE 1933 ACT OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES IN WHICH SHAREHOLDERS RESIDE, NOR HAVE THEY BEEN REGISTERED OR OTHERWISE QUALIFIED FOR DISTRIBUTION UNDER THE LAWS OF ANY OTHER JURISDICTION OUTSIDE OF CANADA. For a discussion of regulatory issues relating to U.S. Shareholders, see “Regulatory Matters — Securities Law Matters — United States”.

THE RCI NON-VOTING SHARES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SEC OR ANY STATE SECURITIES COMMISSION NOR HAS THE SEC OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS CIRCULAR. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.

THE ARRANGEMENT

Background to the Arrangement

The provisions of the Arrangement Agreement are the result of arm’s length negotiations conducted among representatives of Call-Net and RCI, and their legal and financial advisors. The following is a summary of the meetings, negotiations and discussions in which Call-Net participated that preceded the execution of the Arrangement Agreement.

Between April and August 2004, there were preliminary discussions between Call-Net and RCI in respect of a possible transaction. BMO NB assisted Call-Net as its financial advisor in pursuing a transaction with RCI. After signing a confidentiality agreement, RCI was provided access to a data room of confidential information relating to Call-Net. Discussions regarding a proposed transaction extended over a number of weeks. Over the same period, Call-Net and RCI, together with their respective advisors, proceeded with negotiating the terms and conditions of an arrangement agreement. By August 9, 2004, no transaction was consummated and the discussions ceased.

On March 3, 2005, at the invitation of Edward S. Rogers, RCI’s President and Chief Executive Officer, William Linton, Call-Net’s President and Chief Executive Officer, and Mr. Rogers met to discuss, among other things, Mr. Rogers’ outlook on the telecommunications industry, including the rationale for RCI’s acquisition of Microcell Telecommunications Inc., which was completed in November 2004. Mr. Rogers suggested that the parties revisit the possible acquisition of Call-Net by RCI and the two Chief Executive Officers agreed that the topic merited further discussion.

On March 8, 2005, Mr. Tapp, Call-Net’s Chairman, and Mr. Rogers had a discussion regarding a possible transaction and, in particular, the due diligence procedures that would be established. Also on March 8, 2005, the Chief Financial Officers of Call-Net and RCI had a similar discussion regarding the due diligence process in connection with a possible transaction.

On March 9, 2005, Mr. Tapp sent Mr. Rogers a letter confirming certain of the items discussed in their conversation of March 8, 2005. The letter included a draft non-disclosure agreement that provided for, among other things, a one-month exclusivity period in favour of RCI. Later that day, the non-disclosure agreement was entered into and subsequently amended on March 15, 2005.

On March 14, 2005, senior management of both Call-Net and RCI met to discuss the potential transaction as well as various procedural issues, including in respect of due diligence. On March 15, 2005, the Board was convened to discuss the status of the proposed transaction. Senior management of Call-Net advised the Board of the discussions and negotiations that had taken place between Call-Net and RCI up to that time. The Board authorized the commencement of limited due diligence by RCI and agreed to the one-month exclusivity period granted to RCI.

On March 16, 2005, Mr. Linton sent a letter to Mr. Rogers outlining the procedures that would govern RCI’s due diligence review of Call-Net.

On March 31, 2005, Mr. Rogers provided Mr. Tapp with an initial term sheet in respect of the transaction and on April 4, 2005, Mr. Tapp sent a letter to Mr. Rogers responding to the term sheet that had been provided. The letter outlined various concerns in connection with the term sheet, including the proposed consideration, due diligence procedures, representations and warranties and certain of the conditions contemplated in the term sheet. On the same day, RCI provided Call-Net with a draft definitive agreement that reflected the terms included in the initial term sheet and Mr. Rogers called Mr. Linton to express his concerns regarding the imminent expiration of the exclusivity provision.

On April 5, 2005, management updated the Board in respect of the term sheet as well as Call-Net’s response. The Board agreed that it would not extend the exclusivity in favour of RCI.

Over the April 16th-17th, 2005 weekend, Mr. Linton and Mr. Rogers had two separate discussions regarding the outstanding issues in connection with the proposed transaction.

On May 5, 2005, Mr. Linton and Mr. Rogers met and discussed the consideration in connection with the proposed transaction as well as outstanding items. On the same day, the Board met to discuss the status of the proposed transaction and, in particular, the consideration being proposed. The Board concluded that it was not satisfied with the consideration being proposed and instructed BMO NB to conduct analyses with respect to the proposed transaction, including the proposed consideration.

On May 6, 2005, Mr. Linton called Mr. Rogers to discuss the consideration offered and to advise that the Board did not feel that the consideration was adequate. After this discussion, a Board meeting was held whereby the Board determined not to permit further diligence to be undertaken by RCI until an agreement was reached regarding consideration. It was determined that Mr. Tapp should call Mr. Rogers on May 7, 2005 to further discuss the consideration offered.

On May 7, 2005, an agreement was reached regarding consideration, and the Board approved the transaction subject to completion of definitive documentation. Between May 7, 2005 and May 10, 2005, a definitive arrangement agreement was negotiated between the parties and, on May 10, 2005, the Board met to consider the proposed arrangement and to receive presentations from Call-Net’s legal and financial advisors. At the conclusion of that meeting, the Board of Directors proceeded to unanimously approve the Arrangement and resolved to recommend that Shareholders vote in favour of the Arrangement, subject to negotiation and settlement of the Arrangement Agreement in a form acceptable to specified senior officers.

Following the meeting of the Board of Directors of May 10, 2005, Call-Net, RCI and their respective legal advisors finalized the Arrangement Agreement. In the early morning of May 11, 2005, RCI and Call-Net entered into the Arrangement Agreement and, prior to market opening, issued a joint press release announcing the proposed Arrangement.

Description of the Arrangement

The following description of the Arrangement is qualified in its entirety by reference to the full text of the Plan of Arrangement, a copy of which is attached as Schedule 1.1 to the Arrangement Agreement that is attached as Appendix B to this Circular.

The Plan of Arrangement includes, among other things, an exchange of Call-Net Shares for RCI Non-Voting Shares on the basis of 4.25 Call-Net Shares for one RCI Non-Voting Share. If approved, the Arrangement will become effective at the Effective Time (which is expected to be at 12:01 a.m. (Toronto time) on or about July 8, 2005, but in any case, not later than September 30, 2005). At the Effective Time, the following shall occur:


	1.	the Call-Net Rights Plan shall be deemed to have been terminated (and all rights thereunder shall expire) immediately prior to the Effective Time and shall be of no further force or effect;

	2.	each Call-Net Share (other than Call-Net Shares in respect of which the Shareholder has validly exercised his or her right of dissent) shall be deemed to be transferred to Call-Net Acquisition Company, in the case of Non- Taxable Holders, and to RCI, in the case of other Shareholders, for RCI Non-Voting Shares on the basis of one RCI Non-Voting Share for every 4.25 Call-Net Shares;

	3.	each Call-Net Share in respect of which the Shareholder has validly exercised his or her right of dissent shall be deemed to be transferred to Call-Net for cancellation. See “Rights of Dissenting Shareholders”;

	4.	unless RCI otherwise notifies the Secretary of Call-Net in writing prior to the Effective Date, the Call-Net Preferred Share shall be deemed to be redeemed by Call-Net for $1.00, being the redemption price therefor;

	5.	each holder of Call-Net Options outstanding and unexercised immediately prior to the Effective Time (whether or not then vested) shall receive RCI Options in replacement for such Call-Net Options on the basis described under “Arrangements Respecting Call-Net Options and Call-Net PUs”; and

	6.	with respect to any Call-Net PUs outstanding and unexercised immediately prior to the Effective Date (whether or not then vested), in no event shall they represent any entitlement to receive or otherwise


		acquire Call-Net Shares or to acquire RCI Non-Voting Shares, but otherwise the rights of a holder thereof shall be unaffected and each such holder shall be paid on the Effective Date the amount to which such holder is entitled in respect of such holder’s Call-Net PUs.

If the Shareholders approve the Arrangement Resolution on the basis described herein, Articles of Arrangement will be filed with the Director promptly following the Meeting. It is expected that the Arrangement will be effected on or about July 8, 2005.

Expenses of the Arrangement

The combined estimated fees, costs and expenses of Call-Net and RCI in connection with the Arrangement including, without limitation, financial advisor’s fees, filing fees, legal and accounting fees, and printing and mailing costs are anticipated to be approximately $11 million.

Arrangements Respecting Call-Net Options and Call-Net PUs

Pursuant to the terms of the Plan of Arrangement, each holder of Call-Net Options outstanding and unexercised prior to the Effective Date (whether or not then vested) will receive RCI Options on the basis that: (i) such RCI Options will be exercisable to acquire a like number of RCI Non-Voting Shares that each holder of Call-Net Options would have acquired if all such Call-Net Options held by such holder were fully vested and if each such holder had exercised such Call-Net Options immediately prior to the Effective Time and had received Call-Net Shares; and (ii) the vesting, expiry dates and aggregate exercise price of such RCI Options shall be identical to the vesting, expiry dates and aggregate exercise price, respectively, applicable to such Call-Net Options. The foregoing calculations will be applied separately to each grant of Call-Net Options. If the foregoing calculation results in a holder receiving options exerciseable for a fraction of a RCI Non-Voting Share, the number of RCI Options received on the exchange shall be rounded down to the next whole RCI Option and the total exercise price for the RCI Options will be reduced by the exercise price of the fractional RCI Non-Voting Share. Holders of Call-Net Options may, in certain circumstances, elect to increase the exercise price of the RCI Options. Holders of Call-Net Options should consult their own tax advisors respecting the ability to increase the exercise price of the RCI Options in certain circumstances.

Pursuant to the terms of the Arrangement, with respect to any Call-Net PUs outstanding and unexercised immediately prior to the Effective Date (whether or not then vested), in no event shall they represent any entitlement to receive or otherwise acquire Call-Net Shares or to acquire RCI Non-Voting Shares, but otherwise the rights of a holder thereof shall be unaffected and each such holder shall be paid on the Effective Date the amount to which such holder is entitled in respect of such holder’s Call-Net PUs.

Depositary

Call-Net has retained the services of the Depositary for the receipt of the Letters of Transmittal and the certificates representing Call-Net Shares and for the delivery and payment of the consideration payable for the Call-Net Shares. The Depositary will receive reasonable and customary compensation for its services in connection with the Arrangement, will be reimbursed for certain reasonable out-of-pocket expenses and will be indemnified against certain liabilities, including liabilities under securities laws and expenses in connection therewith.

BMO NB Fairness Opinion

that the consideration offered to Shareholders pursuant to the Arrangement is fair, from a financial point of view, to Shareholders.

The BMO NB Fairness Opinion does not constitute a recommendation to Shareholders concerning their votes with respect to the Arrangement Resolution. In rendering the BMO NB Fairness Opinion, BMO NB relied, without independent verification, on financial and other information that was obtained by BMO NB from public sources or that was provided to BMO NB by Call-Net, RCI and their respective affiliates, associates, advisors or otherwise. BMO NB assumed that this information was complete and accurate and did not omit to state any material fact or any fact necessary to be stated to make that information not misleading.

BMO NB is one of Canada’s largest investment banking firms with operations in all facets of corporate and government finance, mergers and acquisitions, equity and fixed income sales and trading and investment research. BMO NB has participated in a significant number of transactions involving private and public companies and has extensive experience in preparing fairness opinions and valuations.

BMO NB has extensive experience in the Canadian telecommunications sector, acting for telecommunications entities providing financial advisory, capital raising, fairness opinions and valuation services.

The BMO NB Fairness Opinion represents the opinion of BMO NB and the form and content thereof has been approved for release by a committee of officers of BMO NB who are experienced in mergers and acquisitions, capital markets, real estate, fairness opinions and valuation matters.

The full text of the BMO NB Fairness Opinion, which sets forth the assumptions made, general procedures followed, matters considered and limitations on the review undertaken by BMO NB, is reproduced as Appendix E to this Circular. The BMO NB Fairness Opinion should be read in its entirety by the Shareholders. The summary of the BMO NB Fairness Opinion described in this Circular is qualified in its entirety by reference to the full text of the BMO NB Fairness Opinion. Call-Net has agreed to pay BMO NB a fee for providing its opinion and for its financial advisory services which are, in part, contingent on the successful completion of the Arrangement. BMO NB has advised that it believes that notwithstanding this fee arrangement, it is independent for purposes of providing the BMO NB Fairness Opinion in connection with the Arrangement. Call-Net has also indemnified BMO NB in respect of certain liabilities that may be incurred by BMO NB in connection with the provision of its services.

Recommendation of the Board of Directors

In making its recommendation, the Board of Directors considered a number of factors, including:


	1.	the exchange ratio of one RCI Non-Voting Share for every 4.25 Call-Net Shares which, based upon the closing price on May 10, 2005 (the trading day immediately prior to the announcement of the Arrangement) of RCI Non-Voting Shares on the TSX of $37.00, represented a premium of approximately 34% and 33% over the closing price of the Common Shares and the Non-Voting Shares, respectively, on the TSX on May 10, 2005;

	2.	management believes that Call-Net’s growth strategy will be more easily achieved as a part of RCI than it would on a stand-alone basis;

	3.	the Arrangement will enable the Shareholders to participate in the future prospects of RCI, including Call-Net;

	4.	RCI has a significantly larger market capitalization than Call-Net and the RCI Non-Voting Shares have greater liquidity than the Call-Net Shares;

	5.	current industry, economic and market conditions and trends;


	6.	historical market prices and trading information with respect to the Call-Net Shares and the RCI Non-Voting Shares;

	7.	information regarding the business, operations, property, assets, financial performance and condition, operating results and prospects of Call-Net and RCI;

	8.	the likelihood that the transactions contemplated in the Arrangement would be completed, given the conditions and regulatory approvals necessary to complete such transactions;

	9.	the BMO NB Fairness Opinion, which concluded that the consideration offered to Shareholders pursuant to the Arrangement is fair, from a financial point of view, to Shareholders;

	10.	the terms of the Arrangement Agreement, which permit the Board of Directors to consider and respond to a Superior Proposal subject to the payment of the Termination Fee to RCI in certain circumstances;

	11.	the requirement that the Arrangement Resolution be passed by at least two-thirds of the votes cast by the Shareholders present in person or represented by proxy at the Meeting, with the holders of the Common Shares and the Non-Voting Shares voting as a single class, on the basis that they are being treated equally under the Arrangement and on the basis that they have substantially the same economic entitlements;

	12.	as at the Effective Time, the Call-Net Rights Plan will no longer be necessary to protect the interests of the Shareholders;

	13.	the procedures by which the Arrangement is to be approved, including the requirement for approval by the Court after a hearing at which fairness will be considered; and

	14.	the availability of rights of dissent to the registered Shareholders with respect to the Arrangement.

Interests of Certain Persons in the Arrangement

In considering the recommendation of the Board of Directors with respect to the Arrangement, Shareholders should be aware that certain members of the Board of Directors and of Call-Net’s management have interests in connection with the transactions contemplated in the Arrangement, including those referred to below, that may present them with actual or potential conflicts of interest in connection with the transactions contemplated in the Arrangement. The Board is aware of these interests and considered them along with the other matters described above in “— Recommendation of the Board of Directors”.

William Linton and five other executives (collectively, the “Executives”) have employment agreements that provide rights to them upon a change of control of Call-Net. The employment agreements provide for, among other things, a requirement to pay those Executives an aggregate of between 1.5 and 2 times, depending on the Executive, the Executive’s annual compensation and highest bonus over the last three fiscal years and a requirement to continue to provide the Executive with various other benefits, if the Executive’s employment is terminated or the Executive resigns as a result of certain changes affecting his or her employment within the first 24 months following a change of control of Call-Net.

In addition, pursuant to the Call-Net Stock Option Plan, all outstanding options automatically vest upon a change of control of Call-Net.

The transactions contemplated by the Arrangement will constitute a change of control of Call-Net for purposes of the employment agreements and the Call-Net Stock Option Plan.

Participants under the Call-Net Restricted Share Unit Plan and Call-Net Deferred Share Unit Plan currently include, among others, certain members of the Board of Directors and senior management of Call-Net. Pursuant to the Arrangement, with respect to any Call-Net PUs outstanding and unexercised immediately prior to the Effective Date (whether or not then vested), in no event shall they represent any entitlement to receive or otherwise acquire Call-Net Shares or to acquire RCI Non-Voting Shares, but otherwise the rights of a holder thereof shall be unaffected and each such holder shall be paid on the Effective Date the amount to which such holder is entitled in respect of such holder’s Call-Net PUs.

In addition, pursuant to the Arrangement Agreement, all rights to indemnification in favour of present and former directors and officers of Call-Net as of the date of the Arrangement Agreement will continue for a period of not less than six years from the Effective Date. As well, RCI is required to use reasonable commercial efforts to secure directors’ and officers’ liability insurance coverage for current and former directors and officers of Call-Net on a six year “trailing” basis or, if such insurance coverage is not available at a reasonable cost, cause Call-Net to maintain, on commercially reasonably terms, its current policy covering claims made prior to or within six years of the Effective Date.

Intentions of Call-Net Directors and Senior Officers

The directors and senior officers of Call-Net, who collectively owned approximately 733,501 Call-Net Shares as of May 18, 2005, which represent approximately 2% of the outstanding Call-Net Shares, have indicated that they intend to vote in favour of the Arrangement Resolution.

Procedure for the Arrangement to Become Effective

The Arrangement is proposed to be carried out pursuant to Section 192 of the CBCA. The following procedural steps must be taken in order for the Arrangement to become effective:


	(a)	the Court must grant the Final Order approving the Arrangement;

	(b)	all conditions precedent to the Arrangement, including, without limitation, the receipt of all regulatory approvals described in “Regulatory Matters” below and further described in the Arrangement Agreement, must be satisfied or waived by the appropriate party; and

	(c)	the Articles of Arrangement in the form prescribed by the CBCA must be filed with the Director under the CBCA.

Shareholder Approval

At the Meeting, Shareholders will be asked to vote to approve the Arrangement Resolution. The approval of the Arrangement Resolution will require the affirmative vote of at least two-thirds of the votes cast by the holders of Call-Net Shares present in person or represented by proxy at the Meeting. The Arrangement Resolution must be passed in order for Call-Net to seek the Final Order and to implement the Arrangement on the Effective Date in accordance with the Final Order.

Court Approval and Completion of the Arrangement

The Arrangement requires approval by the Court. Prior to the mailing of this Circular, Call-Net obtained the Interim Order providing for the calling and holding of the Meeting and other procedural matters. A copy of the Interim Order is attached hereto as Appendix D. The Notice of Application applying for the Final Order is attached hereto as Appendix C.

Subject to the approval of the Arrangement Resolution by the Shareholders at the Meeting, the hearing in respect of the Final Order is currently scheduled to take place on July 7, 2005 at 10:00 a.m. (Toronto time) in the Court at 393 University Ave., Toronto, Ontario or as soon thereafter as is reasonably practicable. Any Shareholder, holder of Preferred Shares, holder of Call-Net Options or holder of Call-Net PUs who wishes to appear or be represented and to present evidence or arguments must serve and file a Notice of Appearance as set out in the Notice of Application for the Final Order and satisfy any other requirements of the Court. The Court will consider, among other things, the fairness and reasonableness of the Arrangement. The Court may approve the Arrangement in any manner the Court may direct, subject to compliance with such terms and conditions, if any, as the Court deems fit.

Assuming the Final Order is granted and the other conditions to closing contained in the Arrangement Agreement are satisfied or waived, it is anticipated that Articles of Arrangement for Call-Net will be filed with the Director under the CBCA to give effect to the Arrangement on or about July 8, 2005.

Subject to obtaining the necessary Shareholder approval, Call-Net currently anticipates making application to the Court for the Final Order on July 7, 2005. The Arrangement will become effective upon receipt by the Director of the Articles of Arrangement and the endorsement by the Director of the Certificate of Arrangement thereon. If the Final Order is obtained on July 7, 2005 in form and substance satisfactory to Call-Net and RCI and all other conditions specified in the Arrangement Agreement are satisfied or waived, Call-Net currently expects the Effective Date will be on or about July 8, 2005 and the Arrangement will become effective on that date.

Although Call-Net’s objective is to have the Effective Date occur as soon as possible after the Meeting, the Effective Date could be delayed for a number of reasons, including an objection before the Court at the hearing of the application for the Final Order or any delay in obtaining any required regulatory approvals. RCI and Call-Net may terminate the Arrangement Agreement whereby the Arrangement will not become effective without prior notice to or action on the part of Shareholders. See “The Arrangement Agreement — Termination”.

Letter of Transmittal

Shareholders must forward properly completed and signed Letters of Transmittal, with accompanying Call-Net Share certificates, in order to be entitled to receive their share certificates representing RCI Non-Voting Shares from the Depositary. It is recommended that Shareholders complete, sign and return the Letters of Transmittal with accompanying Call-Net Share certificates to the Depositary as soon as possible, and preferably prior to 5:00 p.m. (Toronto time) on June 27, 2005.

The following description of certain material provisions of the Arrangement Agreement is a summary only, is not comprehensive and is qualified in its entirety by reference to the full text of the Arrangement Agreement, a copy of which is attached as Appendix B to this Circular.

On May 11, 2005, RCI and Call-Net entered into the Arrangement Agreement, under which it was agreed that RCI would acquire all of the issued and outstanding Call-Net Shares in a share-for-share transaction pursuant to the Arrangement.

In particular, Call-Net has agreed that, until the Effective Date except with the consent of RCI (which consent shall not be unreasonably withheld) or unless otherwise expressly contemplated or permitted by the Arrangement Agreement, each of the Call-Net Entities shall: (i) carry on its business in, and only in, the ordinary course; (ii) not commence a substantial or unusual expansion of its business facilities; (iii) not declare any dividends or distributions; (iv) not amend the constating documents of any of the Call-Net Entities; (v) not allot, reserve, set aside or issue any shares in its capital stock or other equity interests of any of the Call-Net Entities except in specific circumstances; (vi) not amend, vary or modify the Call-Net Stock Option Plan, the Call-Net Restricted Stock Unit Plan or the Call-Net Deferred Share Unit Plan; (vii) not acquire or agree to acquire any Call-Net Shares; (viii) not guarantee the payment of the indebtedness or incur indebtedness relating to an individual amount of $500,000 or more or aggregate amount of $1,000,000 or more; (ix) comply promptly with all requirements of applicable law; (x) not reorganize, amalgamate or merge or permit any of the other Call-Net Entities to do so; (xi) not satisfy or settle any claims, except such as have been fully reserved against in Call-Net’s audited annual consolidated financial statements for the year ended December 31, 2004 or involve the possible payment or receipt of amounts that do not exceed $1,000,000 in the aggregate; (xii) not relinquish any contractual rights except in the ordinary course of business; (xiii) not enter into any swap, hedge, or similar transaction agreement; (xiv) not commence any claim out of the ordinary course of business; (xv) not enter into any material contract that would restrict or otherwise limit or affect the ability of any Call-Net Entity to engage in any activity or to own or deal with any assets or business or to compete with or solicit any Person; (xvi) not enter into any contract that involves the possible payment of amounts in excess of $3,000,000 or receipt of amounts in excess of $5,000,000 over the term of the contract except in accordance with a budget approved by the Board; (xvii) not acquire or enter into any lease of assets or property that would require payment of aggregate consideration of more than $3,000,000 or be material to the Call-Net Entities; (xviii) not enter into any non-arm’s length transactions; (xix) not grant to any of the directors or officers any increase in compensation amounts or any agreement to pay any severance or termination amounts; (xx) use commercially reasonable efforts to maintain existing insurance; (xxi) take all action necessary pursuant to the Call-Net Rights Plan to effect the appropriate waiver; and (xxii) promptly advise RCI upon acquiring knowledge of any event that would render any representation or warranty untrue, inaccurate or incomplete in any material respect, that would reasonably be expected to have a Material Adverse Effect, any breach by Call-Net of any covenant or agreement contained in the Management Agreement and any death, disability, resignation or termination of employment or other departure of any senior officer or senior employee of any of the Call-Net Entities.

In addition, Call-Net is required to: (a) recommend that Shareholders vote in favour of the Arrangement; (b) not withdraw its recommendation; (c) instruct CIBC Mellon to furnish RCI daily status reports as to the tabulation of forms of proxy; (d) apply for and use commercially reasonable efforts to obtain all consents and approvals of third parties; (e) apply for and use commercially reasonable efforts to obtain the Interim Order and Final Order; (f) use commercially reasonable efforts to defend all lawsuits; (g) use commercially reasonable

efforts to have lifted or rescinded any injunction or restraining order; and (h) if for whatever reason, other than as a result of a material breach by RCI of its obligations under the Arrangement Agreement, the Arrangement cannot be completed on the basis contemplated by the Arrangement Agreement, negotiate in good faith with RCI to restructure the transactions contemplated by the Arrangement Agreement on a mutually acceptable basis and with completion of the Arrangement to occur on or before September 30, 2005.

Call-Net has also agreed that during the period subsequent to the Shareholders approving the Arrangement, Call-Net shall take such actions as are necessary or desirable to reorganize the capital and assets of the Call-Net Entities and to take such commercially reasonable actions as RCI may reasonably require to facilitate planning for integration of the Call-Net Entities into RCI’s operations provided no such action will be undertaken if (i) it would reduce the consideration payable to a Shareholder under the Arrangement, (ii) RCI has not agreed to pay the costs and expenses that may be incurred or (iii) Call-Net has not been provided with appropriate undertakings to discharge any security.

Covenants of RCI

In the Arrangement Agreement, RCI has agreed that, among other things, it will use commercially reasonable efforts to: (a) defend all lawsuits and to have lifted or rescinded any injunction or restraining order restricting the consummation of the Arrangement; (b) effect all necessary registrations, filings and submissions to Governmental Entities; (c) use its reasonable efforts to apply for the Interim Order and Final Order and to comply with law; (d) if for whatever reason, other than as a result of a material breach by Call-Net of its obligations under the Arrangement Agreement, the Arrangement cannot be completed on the basis contemplated by the Arrangement Agreement, negotiate in good faith with Call-Net to restructure the transactions contemplated by the Arrangement Agreement on a mutually acceptable basis and with completion of the Arrangement to occur on or before September 30, 2005; (e) continue to provide reasonable access to information concerning the business, assets, liabilities and affairs of RCI; (f) take all action necessary to cause Call-Net to comply with the terms and provisions of the termination entitlements of its management team; (g) not split, combine or reclassify the RCI Non-Voting Shares; (h) promptly advise Call-Net of any event occurring subsequent to the date of the Arrangement Agreement that would render any representation or warranty untrue, or any event that would reasonably be expected to have a Material Adverse Effect on RCI and take any action that would interfere with or be inconsistent with any action contemplated by the Arrangement Agreement; and (i) take all reasonable action and do all things reasonably necessary to complete the transactions.

Covenants of Call-Net Regarding Non-Solicitation/ Cease Negotiations

Call-Net has agreed under the Arrangement Agreement that it will not, directly or indirectly, through any officer, director, employee, representative or agent of Call-Net or any other Call-Net Entity (i) 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, (ii) participate in any discussions or negotiations regarding any Acquisition Proposal, (iii) withdraw or modify in a manner adverse to RCI the approval of the Board of Directors of the transactions contemplated by the Arrangement Agreement, or (iv) accept, approve or recommend any Acquisition Proposal or enter into any agreement related to any Acquisition Proposal.

Call-Net has also agreed: (a) immediately to cease and cause to be terminated any existing discussions or negotiations with any parties (other than RCI) with respect to any potential Acquisition Proposal; (b) 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 (c) immediately to cease to provide any other party with access to information concerning any of the Call-Net Entities and request the return or destruction of all confidential information provided to any third party that has entered into a confidentiality agreement with Call-Net relating to any potential Acquisition Proposal.

Notwithstanding the foregoing, but subject to the notice requirements described below (see “Notice of Superior Proposal Determination”), nothing in the Arrangement Agreement prevents the Board of Directors from (x) complying with Call-Net’s disclosure obligations under applicable law with respect to an unsolicited bona

fide written Acquisition Proposal; (y) considering, negotiating or discussing (and providing non-public information in response to) a Superior Proposal or (z) withdrawing or modifying its recommendation that Shareholders vote in favour of the Arrangement, if the Board of Directors has so determined that an Acquisition Proposal is a Superior Proposal. Call-Net must immediately notify RCI of any Acquisition Proposal or any request for non-public information in connection with an Acquisition Proposal or access to the properties, books or records of any of the Call-Net Entities from any person that informs Call-Net that it is considering making an Acquisition Proposal. Call-Net may provide another person with material non-public information relating to the Call-Net Entities or any of them if it receives a request for such information from a Person who has made an unsolicited bona fide Acquisition Proposal, subject to the execution by such Person of a confidentiality agreement (which shall in no respect be more favourable to such Person than the terms of the confidentiality agreement between RCI and Call-Net), provided however, that the Person making the Acquisition Proposal shall not be precluded under such confidentiality agreement from making an Acquisition Proposal that is a Superior Proposal.

Notice of Superior Proposal Determination

Call-Net has agreed under the Arrangement Agreement that it shall not accept, approve, recommend or enter into any agreement relating to an Acquisition Proposal (other than a confidentiality agreement) on the basis that it would constitute a Superior Proposal unless:


	(a)	the Board of Directors shall have determined in good faith that the Acquisition Proposal constitutes a Superior Proposal;

	(b)	Call-Net has provided RCI with a copy of the Acquisition Proposal document which the Board of Directors has determined would be a Superior Proposal;

	(c)	five business days (the “Response Period”) shall have elapsed from the later of the date RCI receives notice of Call-Net’s proposed determination to accept, approve, recommend or enter into any agreement relating to such Acquisition Proposal, and the date RCI receives a copy of the Acquisition Proposal; and

	(d)	Call-Net is not in any material respect (x) in default under the Arrangement Agreement or (y) in breach of any of its representations or warranties contained in the Arrangement Agreement.

Right to Match

Termination Fee

If the Arrangement Agreement is terminated as a result of any of the following events, Call-Net has agreed to pay a termination fee equal to $10,000,000 (the “Termination Fee”) to RCI no later than the first business day following such event:


	(a)	the Board of Directors withdraws or modifies in a manner adverse to RCI its approval or recommendation of the Arrangement and makes a public announcement to that effect,


	(b)	the Board of Directors recommends any Superior Proposal and makes a public announcement to that effect; or

	(c)	the Board of Directors fails to promptly reaffirm its recommendation of the Arrangement by press release, either after any Acquisition Proposal (that is not determined to be a Superior Proposal) is publicly announced or made, or after RCI increases the consideration offered under the Arrangement to match or better the consideration under a Superior Proposal during the Response Period,

provided in each case that RCI is not in default in the performance of its material obligations under the Arrangement Agreement.

In addition, if the Arrangement Agreement has been terminated without any payment of the Termination Fee and in circumstances where RCI is not in breach of any of its representations, warranties, covenants or other agreements set out in the Arrangement Agreement in any material respect and all approvals required under the Competition Act (Canada) to effect the closing of the transactions contemplated under the Arrangement Agreement have been obtained prior to the termination of the Arrangement Agreement and, within four months after termination, an Acquisition Proposal is consummated that has a value per Call-Net Share greater than the per Call-Net Share value attributed under the transactions contemplated by the Arrangement Agreement, Call-Net shall pay to RCI an amount equal to the Termination Fee.

Termination

The Arrangement Agreement may be terminated prior to completion of the Arrangement: (a) by either RCI or Call-Net, subject to complying with the notice and cure provisions in the Arrangement Agreement, and when not in default in any material respect in the performance of its obligations under the Arrangement Agreement, if any of the conditions precedent to the Arrangement for its benefit or for the mutual benefit of the parties is not fulfilled; (b) by the mutual agreement of Call-Net and RCI (without further action on the part of the Shareholders if terminated after the holding of the Meeting); (c) by Call-Net by notice to RCI, upon any determination by the Call-Net Board of Directors that an Acquisition Proposal constitutes a Superior Proposal, subject to compliance with the notice provisions of the Arrangement Agreement and the payment by Call-Net to RCI of the Termination Fee; (d) by RCI by notice to Call-Net upon the occurrence of any of the events that would give rise to the obligation of Call-Net to pay to RCI a Termination Fee; (e) by either RCI or Call-Net by notice to the other upon the failure of the Shareholders to approve the Arrangement at the Meeting; or (f) by either Call-Net or RCI, subject to the obligation of both of them to reasonably consider, and co-operate with one another in, amending the Arrangement Agreement without prejudice to their respective shareholders, if any law is passed that makes consummation of the Arrangement illegal or otherwise prohibited.

If the Arrangement does not become effective on or prior to September 30, 2005, the Arrangement Agreement will terminate unless Call-Net and RCI mutually agree to extend such date or unless the failure of the Arrangement to become effective is the result of the inability to obtain a required governmental or regulatory approval or waiver, in which case the date shall be automatically extended until up to October 31, 2005.

REGULATORY MATTERS

The consummation of the Arrangement is, or may be, conditional upon certain filings with, notices to and consents, approvals and actions of, various Governmental Entities with respect to the transactions contemplated by the Arrangement Agreement being made and received prior to the Effective Time. These approvals are summarized below.

Securities Law Matters-Canada

The RCI Non-Voting Shares to be issued in exchange for Call-Net Shares pursuant to the Arrangement will be issued in reliance on exemptions from prospectus and registration requirements of applicable Canadian securities laws and will generally be “freely tradeable” (other than as a result of any “control block” restrictions which may arise by virtue of the ownership thereof) under applicable securities laws of the provinces and territories of Canada, subject to the usual conditions that no unusual effort is made to prepare the market for any

such resale or to create a demand for the securities which are subject to any such resale and no extraordinary commission or consideration is paid in respect thereof and subject, in the case of the Province of Quebec, to the receipt of regulatory approval.

Securities Law Matters-United States

Exemption from U.S. Registration

The RCI Non-Voting Shares issuable in connection with the Arrangement will be issued in reliance upon the exemption from registration provided by Section 3(a)(10) of the 1933 Act and exemptions provided under the securities laws of each state of the United States in which Shareholders reside. Section 3(a)(10) of the 1933 Act exempts from registration a security that is issued in exchange for outstanding securities where the terms and conditions of such issuance and exchange are approved, after a hearing upon the fairness of such terms and conditions at which all persons to whom it is proposed to issue securities in such exchange have the right to appear, by a court or by a governmental authority expressly authorized by law to grant such approval. The Final Order of the Court will, if granted, constitute a basis for the exemption from the registration requirements of the 1933 Act with respect to the RCI Non-Voting Shares issued in connection with the Arrangement.

Resale of RCI Non-Voting Shares in the United States

In certain circumstances, the 1933 Act will impose restrictions on the resale of RCI Non-Voting Shares received pursuant to the Arrangement in the United States. The restrictions on resale imposed by the 1933 Act will depend on whether the recipients of RCI Non-Voting Shares are “affiliates” of RCI or were “affiliates” of Call-Net prior to the Arrangement. For the purpose of the 1933 Act, an “affiliate” of an issuer is a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, RCI or Call-Net, as the case may be. “Control” means the possession, direct or indirect, of the power to direct or cause direction of the management and policies of an issuer, whether through the ownership of voting securities, by contract or otherwise.

Shareholders who were not affiliates of Call-Net prior to the Arrangement and are not affiliates of RCI after consummation of the Arrangement may freely resell RCI Non-Voting Shares received pursuant to the Arrangement in the United States. Any Shareholder who was an affiliate of Call-Net prior to the Arrangement or is or becomes an affiliate of RCI may not resell RCI Non-Voting Shares received pursuant to the Arrangement except in transactions permitted by the resale provisions of Rule 145(d) promulgated under the 1933 Act or as otherwise permitted under the 1933 Act. Sales under Rule 145(d) require compliance, during prescribed periods following the acquisition of securities pursuant to the Arrangement, with certain volume limitations and current public information and manner of sale requirements.

The foregoing discussion is only a general overview of the requirements of the U.S. securities laws that may be applicable to the resale of RCI Non-Voting Shares received pursuant to the Arrangement. Recipients of RCI Non-Voting Shares are urged to obtain legal advice to ensure that their resale of such securities complies with applicable U.S. securities laws. Further information applicable to U.S. Shareholders is disclosed in this Circular under the heading “Notice to U.S. Shareholders”.

Competition Act (Canada)

The Arrangement constitutes a “merger” for purposes of the Competition Act (Canada) (the “Competition Act”). Pursuant to section 92 of the Competition Act, the Competition Tribunal (the “Tribunal”), upon the application of the Commissioner of Competition or a person duly authorized to exercise the powers and perform the duties of the Commissioner of Competition (the “Commissioner”), may issue an order, among other things, to dissolve a merger or prohibit a proposed merger from proceeding, if the Tribunal finds that such merger or proposed merger prevents or lessens, or is likely to prevent or lessen, competition substantially. In addition, under the Competition Act, the Tribunal, upon the application of the Commissioner, may in certain circumstances make a temporary order (with, or in some cases without, prior notice), among other things, to prevent a proposed merger from proceeding for a stated period of time (subject in some cases to prescribed time limits). No application may be made by the Commissioner under section 92 in respect of a merger more than three years

after the merger has been substantially completed, nor may the Commissioner apply to the Tribunal for an order in respect of a merger in respect of which an advance ruling certificate (“ARC”) has been issued by the Commissioner pursuant to section 102 of the Competition Act, solely on the basis of information that is the same or substantially the same as that upon which the ARC was issued, provided that the merger is substantially completed within one year after the ARC is issued.

In addition, Part IX of the Competition Act establishes a regime pursuant to which certain mergers may not be completed until notice as prescribed by the Competition Act has been given to the Commissioner and certain waiting period requirements have been satisfied. A merger transaction that is subject to the notification regime (a “Notifiable Transaction”) and that is notified pursuant to the short-form pre-merger notification procedure contained in Part IX of the Competition Act may not be completed until 14 days after the short-form pre-merger notification has been filed with the Commissioner unless prior to the expiration of that time the Commissioner (i) gives notice that she does not intend to make an application to the Tribunal under section 92 of the Competition Act in respect of the proposed merger; (ii) waives the obligation on the part of the parties to the merger to notify the Commissioner; or (iii) issues an ARC in respect of the proposed merger, provided that, before such time, the Commissioner does not give notice to the parties to a merger that a long-form pre-merger notification filing is required to be made. A merger transaction that is subject to the notification regime and that is notified pursuant to the long-form pre-merger notification procedure contained in Part IX of the Competition Act (either at the election of the notifying parties or on notice from the Commissioner) may not be completed until 42 days after the long-form pre-merger notification has been filed with the Commissioner unless prior to the expiration of that time the Commissioner (i) gives notice that she does not intend to make an application to the Tribunal under section 92 of the Competition Act in respect of the proposed merger; (ii) waives the obligation on the part of the parties to the merger to notify the Commissioner; or (iii) issues an ARC in respect of the proposed merger.

There is no obligation to comply with Part IX of the Competition Act in respect of a merger for which an ARC has been issued within one year prior to the substantial completion of the merger or in respect of which the Commissioner has waived the obligation to notify the Commissioner and supply information because substantially similar information was previously supplied in relation to a request for an ARC.

Note that the Commissioner’s review of a Notifiable Transaction may take more or less time than the statutory waiting period. Upon completion of the Commissioner’s review of a Notifiable Transaction, the Commissioner may decide, among other things, to:


	(a)	challenge the Notifiable Transaction, as described above;

	(b)	issue a letter (a “No Action Letter”) stating that the Commissioner is of the view that grounds do not exist to initiate proceedings in respect of the transaction before the Tribunal under the merger provisions of the Competition Act at the then current time but that the Commissioner retains the authority to do so for three years after substantial completion of the Notifiable Transaction; or

	(c)	issue an ARC in respect of the Notifiable Transaction.

Unless an ARC is issued in respect of the Arrangement, or unless the Commissioner waives the obligation to notify the Commissioner and provide information in respect of the Arrangement, the Arrangement will be subject to mandatory pre-merger notification under Part IX of the Competition Act. On May 19, 2005, the parties to the Arrangement made an application to the Commissioner for an ARC or, in the alternative, a No-Action Letter, in respect of the Arrangement and the parties to the Arrangement anticipate filing their respective short-form notifications in respect of the Arrangement with the Commissioner on or before May 31, 2005.

Based on the information available to it, Call-Net is of the view that the Arrangement can be effected in compliance with Canadian competition laws. However, there is no assurance that a challenge to the Arrangement under the Competition Act will not be made or, if a challenge is made, what the result would be.

Federal Communications Commission

As a condition to the consummation of the Arrangement, Call-Net will seek to obtain any prior approvals to the extent the parties determine that such approval is required by the United States Federal Communications Commission (the “FCC”). If it is determined that the parties are required to obtain such approval, an application will be submitted promptly.

Stock Exchange Approval

RCI will apply to list the RCI Non-Voting Shares issuable by RCI under the Arrangement on the TSX and on the NYSE.

PROCEDURES FOR EXCHANGE OF SHARE CERTIFICATES BY SHAREHOLDERS

Enclosed with this Circular is a Letter of Transmittal (printed on yellow paper) that is being delivered to registered Shareholders. The Letter of Transmittal, when properly completed and duly executed and returned together with a certificate or certificates for Call-Net Shares and all other required documents, will enable each Shareholder to obtain a certificate representing whole RCI Non-Voting Shares on the basis of one RCI Non-Voting Share for every 4.25 Call-Net Shares previously held and represented by the deposited share certificate or certificates. No fractional RCI Non-Voting Shares will be issued.

In lieu of fractional RCI Non-Voting Shares, each Shareholder otherwise entitled to a fractional interest in an RCI Non-Voting Share will receive a cheque following the Effective Date in an amount equal to such fractional interest multiplied by $37.00. RCI shall provide the Depositary with sufficient funds to enable the Depositary to make such payments.

Any use of the mail to transmit a certificate for Call-Net Shares and a related Letter of Transmittal is at the risk of the Shareholder. If these documents are mailed, it is recommended that registered mail, with return receipt requested, properly insured, be used.

Whether or not Shareholders forward the certificates representing their Call-Net Shares, upon completion of the Plan of Arrangement on the Effective Date, Shareholders will cease to be Shareholders as of the Effective Date and will only be entitled to receive the share certificates representing that number of RCI Non-Voting Shares to which they are entitled under the Plan of Arrangement or, in the case of Shareholders who properly exercise dissent rights, the right to receive fair value for their Call-Net Shares in accordance with the dissent procedures. See “Rights of Dissenting Shareholders”.

Certificates representing the appropriate number of RCI Non-Voting Shares issuable to a former holder of Call-Net Shares who has complied with the procedures set out above, together with a cheque in the amount, if any, payable in lieu of fractional RCI Non-Voting Shares will as soon as practicable after the Effective Date and, in any event, within five business days after the later of the Effective Date and delivery to CIBC Mellon of the duly completed and executed Letter of Transmittal, certificate(s) representing the Call-Net Shares and all other required documents, (i) be forwarded to the holder at the address specified in the Letter of Transmittal by first class mail, postage prepaid, or (ii) be made available at the principal offices of the Depositary in Toronto for pick up by the holder as requested by the holder in the Letter of Transmittal.

Where a certificate for Call-Net Shares has been destroyed, lost or mislaid, the registered holder of that certificate should immediately contact CIBC Mellon, toll free at 1-800-387-0825, or in the Toronto area at (416) 643-5500, regarding the issuance of a replacement certificate upon the holder satisfying such requirements as may be imposed by Call-Net in connection with issuance of the replacement certificate.

It is recommended that Shareholders complete, sign and return the Letters of Transmittal with accompanying Call-Net Share certificates to the Depositary as soon as possible and preferably prior to 5:00 p.m. (Toronto time) on June 27, 2005.

Shareholders who hold Call-Net Shares registered in the name of a broker, investment dealer, bank, trust company or other intermediary should contact the intermediary for instructions and assistance in providing details for registration or delivery of their RCI Non-Voting Shares.

ELIGIBILITY FOR INVESTMENT IN CANADA

Provided the RCI Non-Voting Shares are listed on a prescribed stock exchange in Canada (which currently includes the TSX), the RCI Non-Voting Shares will be qualified investments under the ITA and the regulations thereunder for trusts governed by registered retirement savings plans (“RRSPs”), registered retirement income funds (“RRIFs”), deferred profit sharing plans (“DPSPs”) and registered education savings plans (“RESPs”).

Based upon an officer’s certificate provided by RCI, the RCI Non-Voting Shares will not, as of the date of this Circular, constitute “foreign property” to RRSPs, RRIFs and DPSPs and certain other persons to whom Part XI of the ITA is applicable. As part of the February 23, 2005 Federal Budget, the Minister of Finance (Canada) announced that the restrictions contained in the ITA in respect of the ownership of foreign property will be eliminated effective January 1, 2005 and this proposal was included in a Bill tabled by the Minister of Finance in the House of Commons on March 24, 2005. There can be no assurance that this proposal will be enacted.

MATERIAL CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

In the opinion of Goodmans LLP, counsel to Call-Net, the following are summaries of certain Canadian federal income tax considerations under the ITA generally applicable to a Shareholder in respect of the Arrangement who, for purposes of the ITA and at all relevant times holds Call-Net Shares and will hold any RCI Non-Voting Shares as capital property and who deals at arm’s length with, is not affiliated with, Call-Net or RCI and will not, either alone or together with other persons with whom it does not deal at arms’ length, either control RCI immediately following the Effective Date or beneficially own shares of RCI which have a fair market value in excess of 50% of the fair market value of all RCI shares immediately following the Effective Date. Generally, holders of Call-Net Shares and RCI Non-Voting Shares will be considered to hold such shares as capital property unless they are held as part of a business of buying and selling securities or have been acquired in a transaction or transactions considered to be an adventure in the nature of trade.

These summaries are based upon the current provisions of the ITA and the regulations thereunder, all specific proposals to amend the ITA and regulations publicly announced by or on behalf of the Minister of Finance (Canada) prior to the date hereof (the “Tax Proposals”), a certificate of an officer of RCI as to certain factual matters, and counsel’s understanding of the current administrative practices of the CRA. No assurances can be given that the Tax Proposals will be enacted as proposed, if at all.

The ITA contains provisions relating to securities held by certain financial institutions (the “mark-to-market rules”). These summaries do not take into account these mark-to-market rules. Shareholders that are “financial institutions” for purposes of these rules should consult their own tax advisors.

These summaries are not exhaustive of all possible Canadian federal income tax considerations and, except for the Tax Proposals, do not take into account or anticipate any changes in law, whether by legislative, governmental or judicial decision or action, or any changes in the administrative practices of the CRA. These summaries do not take into account income tax legislation of any province, territory or foreign jurisdiction. Provisions of provincial income tax legislation vary from province to province in Canada and may differ from federal income tax legislation.

These summaries are of a general nature only and are not intended to be, nor should they be construed to be, legal or tax advice to any particular Shareholder. Accordingly, Shareholders should consult their own tax advisors for advice with respect to the income tax consequences to them of disposing of their Call-Net Shares and holding and disposing of RCI Non-Voting Shares having regard to their own particular circumstances. Shareholders to whom this summary does not apply may, among other things, realize a taxable gain or income as a result of the Arrangement.

Residents of Canada

The following summary is applicable to a Shareholder who, at all relevant times, is, or is deemed to be, resident in Canada for purposes of the ITA and any applicable income tax treaty or convention and who is not exempt from tax under Part I of the ITA.

A Shareholder whose Call-Net Shares might not otherwise qualify as capital property may make an irrevocable election in accordance with subsection 39(4) of the ITA to have them and all other “Canadian securities” (as defined in the ITA) owned by such Shareholder in the taxation year of the election and in all subsequent taxation years deemed to be capital property.

A Shareholder who receives an RCI Non-Voting Share in exchange for Call-Net Shares will be deemed to have disposed of such Call-Net Shares for proceeds of disposition equal to the Shareholder’s aggregate adjusted cost base in respect of such shares, immediately before the exchange, and to have acquired the RCI Non-Voting Share received in exchange therefor at a cost equal to such proceeds of disposition, unless the Shareholder chooses to report any portion of the capital gain or loss otherwise determined from such disposition in his return of income for the year of disposition. Under the current administrative practice of the CRA, a Shareholder who receives cash of $200 or less in lieu of a fractional RCI Non-Voting Share may either include the gain or loss on the partial disposition of the fractional RCI Non-Voting Share in computing income or reduce the adjusted cost base to the Shareholder of his RCI Non-Voting Shares by the amount of the cash.

A Shareholder who chooses to include in computing the Shareholder’s income any portion of the capital gain or capital loss, otherwise determined, from such disposition will be considered to have disposed of his or her Call-Net Shares for proceeds of disposition equal to the fair market value as at the time of acquisition of the RCI Non-Voting Shares acquired by such Shareholder on the exchange (plus any cash received by such Shareholder in lieu of a fractional RCI Non-Voting Share). As a result, the Shareholder will in general realize a capital gain (or capital loss) to the extent that such proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base to the Shareholder of the Call-Net Shares. The cost to a Shareholder of any RCI Non-Voting Share acquired on the exchange will be equal to the fair market value of such share at the time of acquisition.

The cost of the RCI Non-Voting Shares acquired by a Shareholder will be averaged with the adjusted cost base of all other RCI Non-Voting Shares owned by the Shareholder immediately prior to such acquisition for the purpose of determining thereafter the adjusted cost base of each RCI Non-Voting Share held by such Shareholder.

Disposition of RCI Non-Voting Shares

A holder of RCI Non-Voting Shares acquired pursuant to the Arrangement will realize a capital gain (or a capital loss) on a subsequent disposition or deemed disposition of such shares equal to the amount by which the proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the holder’s aggregate adjusted cost base of such RCI Non-Voting Shares. See “Taxation of Capital Gains and Capital Losses” below.

Dividends on RCI Non-Voting Shares

Dividends received and deemed received on RCI Non-Voting Shares acquired pursuant to the Arrangement will be included in the recipient’s income for the purposes of the ITA. Such dividends received by an individual (including a trust) will be subject to the gross up and dividend tax credit rules normally applicable to dividends received from taxable Canadian corporations. A holder that is a corporation will include such dividends in computing its income and generally will be entitled to deduct the amount of such dividends in computing its taxable income. A holder that is a “private corporation” or “subject corporation” (as such terms are defined in the ITA) may be liable under Part IV of the ITA to pay a refundable tax of 33¹/3% of dividends received or deemed to be received on the RCI Non-Voting Shares to the extent such dividends are deductible in computing the holder’s taxable income.

Taxation of Capital Gains and Capital Losses

A holder will be required to include in income one-half of the amount of any capital gain (a “taxable capital gain”) and will generally deduct one-half of the amount of any capital loss (an “allowable capital loss”) against taxable capital gains realized by such holder in the year realized. Allowable capital losses in excess of taxable capital gains may be carried back and deducted in any of the three preceding years or carried forward and deducted in any following year against taxable capital gains realized in such year to the extent and under the circumstances described in the ITA. In general, a capital loss otherwise arising on the disposition of a Call-Net Share (or an RCI Non-Voting Share) by a corporation may be reduced by dividends previously received or deemed to have been received thereon. Similar rules may also apply in circumstances where a corporation is a member of a partnership or a beneficiary of a trust that owns Call-Net Shares (or RCI Non-Voting Shares). Holders to whom these rules may be relevant should consult their own tax advisors.

A “Canadian-controlled private corporation” as defined in the ITA may be liable to pay, in addition to tax otherwise payable under the ITA, a refundable tax of 6²/3% of its “aggregate investment income”. For this purpose, investment income will include taxable capital gains. Capital gains realized by individuals and certain trusts may give rise to alternative minimum tax.

Dissenting Shareholders

A Shareholder who exercises dissent rights under the Arrangement and who receives from Call-Net payment of the fair market value of the Call-Net Shares held by such Dissenting Shareholder will be deemed to have received a dividend equal to the amount by which the amount of the payment (excluding the amount of any interest awarded by the court) exceeds the paid-up capital (for purposes of the ITA) of such Shareholder’s Call-Net Shares. Counsel is advised that the amount of the paid-up capital of a Call-Net Share is significantly less than its current fair market value.

The Canadian federal tax consequences to a Shareholder of such a deemed dividend are generally the same as those described under “Dividends on RCI Non-Voting Shares” However, in the case of a Shareholder that is a corporation, in some circumstances all or part of any dividend deemed to be received by the corporation on the Call-Net Shares may be treated as proceeds of disposition of the Call-Net Shares for the purposes of computing the Shareholder’s capital gain on the disposition of such shares, and not as a dividend. Accordingly, Shareholders that are corporations should consult their tax advisors for specific advice with respect to the income tax consequences of exercising dissent rights in respect of the Arrangement.

The difference between the amount received (excluding the amount of any interest ordered by a court) and the amount of any deemed dividend will be treated as proceeds of disposition of Call-Net Shares for the purposes of computing any capital gain or capital loss arising on the disposition of such shares. A capital loss arising in such circumstances may be reduced by dividends previously received or deemed to have been received on Call-Net Shares as described above under “Taxation of Capital Gains and Capital Losses”.

Any interest awarded to a Dissenting Shareholder by a court will be included in the Shareholder’s income for Canadian tax purposes.

Non-Residents of Canada

The following summary is generally applicable to a Shareholder who, at all relevant times, is neither a resident, nor deemed to be a resident, of Canada for purposes of the ITA and any applicable tax treaty or convention, who does not use or hold, and is not deemed to use or hold, the Call-Net Shares or RCI Non-Voting Shares in carrying on a business in Canada and who is not a non-resident insurer (a “Non-Resident Holder”).

A Non-Resident Holder of Call-Net Shares for whom the Call-Net Shares are not taxable Canadian property will not be subject to tax under the ITA on the disposition of such shares under the Arrangement. Similarly, provided the RCI Non-Voting Shares acquired pursuant to the Arrangement are not taxable Canadian property to a Non-Resident Holder, the holder will not be subject to tax under the ITA on any capital gain realized on the disposition or deemed disposition of such RCI Non-Voting Shares.

Generally, any Call-Net Shares or RCI Non-Voting Shares, as the case may be, will not be taxable Canadian property to a Non-Resident Holder at a particular time provided that such shares are listed on a prescribed stock exchange (which currently includes the TSX) at that time and at no time during the five-year period immediately preceding the disposition of Call-Net Shares or RCI Non-Voting Shares, as the case may be, did the holder, persons with whom the holder does not deal at arm’s length, or such holder together with such persons, own or have an interest in or an option in respect of, 25% or more of the issued shares of any class or series of Call-Net or RCI, as the case may be. Notwithstanding the foregoing, a Call-Net Share or RCI Non-Voting Share, as the case may be, may also be deemed to be taxable Canadian property to a Non-Resident Holder in certain circumstances specified in the ITA. Provided that the Call-Net Shares are listed on a prescribed stock exchange at the time of disposition of such shares, the withholding and notification provisions of section 116 of the ITA will not apply to a Non-Resident Holder.

A Non-Resident Holder who receives an RCI Non-Voting Share for his Call-Net Shares will be deemed to have disposed of such Non-Resident Holder’s Call-Net Shares for proceeds of disposition equal to the Non-Resident Holder’s aggregate adjusted cost base in respect of such shares immediately before the exchange, and to have acquired the RCI Non-Voting Share received in exchange therefor at a cost equal to such proceeds of disposition unless the Non-Resident Holder chooses to report any portion of the gain or loss otherwise determined from such disposition in his return of income for the year of disposition. Under the current administrative practice of the CRA, a Non-Resident Holder who receives cash of $200 or less in lieu of a fractional RCI Non-Voting Share may either include the gain or loss on the partial disposition of the fractional RCI Non-Voting Share in computing income or reduce the adjusted cost base to the Non-Resident Holder of his RCI Non-Voting Shares by the amount of the cash. If Call-Net Shares constitute taxable Canadian property to a Non-Resident Holder, then the RCI Non-Voting Shares received by the Non-Resident Holder in exchange for such Call-Net Shares will be deemed to be taxable Canadian property to the Non-Resident Holder.

A Non-Resident Holder who chooses to include in computing the Non-Resident Holder’s income any portion of the capital gain or capital loss, otherwise determined, from such disposition will be considered to have disposed of his or her Call-Net Shares for proceeds of disposition equal to the fair market value as at the time of acquisition of the RCI Non-Voting Shares acquired by such Shareholder on the exchange (plus any cash received by such Shareholder in lieu of a fractional RCI Non-Voting Share). As a result, the Non-Resident Holder will in general realize a capital gain (or capital loss) to the extent that such proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base to the Non-Resident Holder of the Call-Net Shares. The cost to a Non-Resident Holder of any RCI Non-Voting Share acquired on the exchange will be equal to the fair market value of such share at the time of acquisition.

The cost of the RCI Non-Voting Shares acquired by a Non-Resident Holder will be averaged with the adjusted cost base of all other RCI Non-Voting Shares owned by the Non-Resident Holder immediately prior to such acquisition for the purpose of determining thereafter the adjusted cost base of each RCI Non-Voting Share held by such Non-Resident Holder.

If RCI Non-Voting Shares constitute or are deemed to constitute taxable Canadian property to a particular Non-Resident Holder, on the disposition or deemed disposition thereof by a Non-Resident Holder, such holder will realize a capital gain (or capital loss) generally computed in the manner described above under “Residents of Canada”. Any such capital gain may be exempt from tax under the ITA under the terms of an income tax treaty or convention between Canada and the country in which the Non-Resident Holder resides.

If the RCI Non-Voting Shares constitute or are deemed to constitute taxable Canadian property to a Non-Resident Holder and the disposition of such shares by the Non-Resident Holder gives rise to a capital gain which is not exempt from Canadian tax under the terms of an applicable income tax treaty or convention, the tax consequences as described above under “Residents of Canada — Taxation of Capital Gains and Capital Losses” will generally apply. Non-Resident Holders of RCI Non-Voting Shares should consult their own tax advisors for advice having regard to their particular circumstances.

If the Call-Net Shares or RCI Non-Voting Shares are “treaty-protected property” as defined in the ITA, a taxable capital gain or allowable capital loss resulting from a disposition of such shares will not be included or deducted in computing the non-resident Shareholder’s income for purposes of the ITA. Shares owned by a non-

resident Shareholder generally will be treaty-protected property if the gain from a disposition of such property would, because of an applicable income tax treaty, be exempt from tax under the ITA.

Dividends on RCI Non-Voting Shares

Dividends on the RCI Non-Voting Shares paid or credited or deemed to be paid or credited to a Non-Resident Holder will be subject to withholding tax under the ITA at a rate of 25%, subject to reduction under the provisions of an applicable income tax treaty or convention.

Dissenting Shareholders

A Non-Resident Holder who exercises dissent rights under the Arrangement and who receives from Call-Net payment of the fair market value of the Call-Net Shares held by such dissenting Non-Resident Holder will be deemed to receive a dividend in the amount by which the amount of the payment (excluding the amount of any interest awarded by a court) exceeds the paid-up capital (for purposes of the ITA) of such Non-Resident Holder’s Call-Net Shares. Counsel is advised that the amount of the paid-up capital of a Call-Net Share is significantly less than its current fair market value. The amount of such dividend deemed to be received, and the amount of any interest awarded to the Non-Resident Holder by a court, will be subject to Canadian withholding tax at a rate of 25% unless the rate is reduced under the provisions of an applicable income tax treaty or convention. Non-Resident Holders should consult their own tax advisors with respect to the availability of any relief under the terms of any applicable income tax treaty or convention in their particular circumstances.

Optionholders

Call-Net Optionholders Resident in Canada

The following portion of this summary is applicable to holders of Call-Net Options who are resident or deemed to be resident in Canada, who are current or former employees of Call-Net (or any subsidiary thereof), who deal at arm’s length with such corporation and who received their Call-Net Options in respect of, in the course of, or by virtue of, employment and at a time when Call-Net was not a “Canadian-controlled private corporation” within the meaning of the ITA.

Exercise of Call-Net Options

Call-Net Optionholders who exercise their Call-Net Options will be subject to income tax consequences arising on such exercise which are not addressed in this summary and which may be relevant to a Call-Net Optionholder’s decision as to whether to exercise his or her Call-Net Options. Call-Net Optionholders who are considering the exercise of their Call-Net Options should consult their own tax advisors to determine the tax consequences to them of the exercise.

Receipt of RCI Options by Call-Net Optionholders

The terms of the Arrangement provide that Call-Net Options which are not conditionally exercised will be exchanged for options to acquire RCI Non-Voting Shares. Provided that the difference between the value of the RCI Non-Voting Shares available to the holder under the RCI Option immediately after the conversion and the amount payable by the holder under the RCI Option does not exceed the difference between the value of the Call-Net Share available to the holder under the Call-Net Option immediately before the conversion and the amount payable by the holder under the Call-Net Option to acquire such Call-Net Share, a holder of a Call-Net Option whose option is exchanged solely for an RCI Option should not realize any immediate taxable income as a result of the conversion. Call-Net Optionholders should consult their own tax advisors respecting the ability to increase the exercise price of the RCI Option in certain circumstances. For the purposes of the ITA, the holder will be deemed not to have disposed of the Call-Net Option, and the RCI Option will be deemed to be the same as, and a continuation of, the prior Call-Net Option. In the event that there is such an excess difference in value, the holder will be treated as having disposed of the Call-Net Option, and may be required to include in income under the ITA in the taxation year of the disposition, the value of the RCI Option. Call-Net Optionholders should consult their own tax advisors in this regard.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material United States Federal income tax consequences of the Arrangement and the ownership and disposition of RCI Non-Voting Shares to Shareholders. This discussion is based on the United States Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations, administrative rulings and judicial decisions, all as currently in effect and which are subject to change, possibly with retroactive effect.

This discussion assumes that Shareholders hold their Call-Net Shares, and will hold any RCI Non-Voting Shares received in the Arrangement, as capital assets within the meaning of Section 1221 of the Code. This discussion also assumes that neither RCI nor Call-Net is, and neither has ever been, a passive foreign investment company for United States Federal income tax purposes (“PFIC”). A foreign corporation is a PFIC for a particular taxable year if (i) 75% or more of its gross income for the taxable year is passive income or (ii) at least 50% of the average value of its assets held during the taxable year produce or are held for the production of passive income. Considering the nature of their respective business activities and earnings, neither RCI nor Call-Net believes that it is, or has ever been, a PFIC.

This discussion does not address all aspects of United States Federal income taxation that may be relevant to particular Shareholders in light of their personal investment circumstances or to Shareholders subject to special treatment under the United States Federal income tax laws such as:


	•	insurance companies;

	•	tax-exempt organizations;

	•	dealers in securities or foreign currencies;

	•	banks;

	•	persons that hold Call-Net Shares or will hold RCI Non-Voting Shares as part of a straddle, hedge, constructive sale or conversion transaction;

	•	United States Holders (as defined below) that have a functional currency other than the United States dollar;

	•	partnerships, S corporations, mutual funds, regulated investment companies, real estate investment trusts and investors in such entities;

	•	shareholders who acquired their Call-Net Shares through the exercise of options or otherwise as compensation or through a tax-qualified retirement plan;

	•	holders of options granted under any Call-Net benefits plan; or

	•	Non-United States Holders (as defined below) who are subject to United States Federal income tax as the result of: (1) the conduct of a trade or business in the United States, (2) the maintenance of a permanent establishment in the United States, or (3) the presence of such Non-United States Holder in the United States for 183 days or more in a taxable year.

Holders of Call-Net Shares are urged to consult their own tax advisors regarding the specific tax consequences to them of the Arrangement, including the applicability and effect of Federal, state, local and foreign income and other tax law.

For purposes of this discussion, a “United States Holder” means a beneficial owner of Call-Net Shares that is:


	•	a citizen or resident alien individual of the United States;

	•	a corporation or other entity taxable as a corporation created or organized under the laws of the United states or any of its political subdivisions;


	•	a trust if a United States court is able to exercise primary supervision over the administration of the trust and one or more United States fiduciaries have the authority to control all substantial decisions of the trust; or

	•	an estate that is subject to United States Federal income tax on its income regardless of its source.

A “Non-United States Holder” is a beneficial owner of Call-Net Shares that is not a United States Holder. If a partnership holds Call-Net Shares, the tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. If you are a partner in a partnership holding Call-Net Shares, you should consult your own tax advisor.

United States Holders of Call-Net Shares

Exchange of Call-Net Shares for RCI Non-Voting Shares

A United States Holder will generally recognize gain or loss for United States Federal income tax purposes as a result of the Arrangement in an amount equal to the difference between (i) such holder’s adjusted tax basis in its Call-Net Shares transferred in the Arrangement and (ii) the fair market value of the RCI Non-Voting Shares received in the Arrangement. Any such gain or loss will generally be capital gain or loss and will be long-term gain or loss if, on the date of the Arrangement, the Call-Net Shares have been held for more than one year. In the case of a United States Holder that is an individual, long-term capital gain will be eligible for a reduced rate of taxation. The deductibility of capital losses is subject to limitations. The United States Holder’s tax basis in the RCI Non-Voting Shares received in the Arrangement will be equal to the fair market value of those shares on the day received, and the holding period of those shares will begin on the day after they are received.

For foreign tax credit limitation purposes, gain or loss recognized on the exchange of Call-Net Shares for RCI Non-Voting Shares pursuant to the Arrangement will generally be United States source income or loss.

Dissenting Shareholders

A United States Holder who exercises dissent rights under the Arrangement and receives payment of the fair value of its Call-Net Shares will generally recognize gain or loss in an amount equal to the difference between the holder’s adjusted tax basis in its Call-Net Shares and the cash received in exchange therefor. Any such gain or loss will generally be capital gain or loss and will be long-term gain or loss if the Call-Net Shares have been held for more than one year on the date of the disposition. In the case of a United States Holder that is an individual, long-term capital gain will be eligible for a reduced rate of taxation. The deductibility of capital losses is subject to limitations. For foreign tax credit limitation purposes, gain or loss recognized on the exchange of Call-Net Shares for cash will generally be United States source income or loss. Any gain or loss from currency exchange fluctuations between the date of the disposition of the Call-Net Shares and the conversion of the sales proceeds into United States dollars will be United States source ordinary income or loss.

Ownership of RCI Non-Voting Shares

Distributions

Distributions paid out of RCI’s current or accumulated earnings and profits, as determined for United States Federal income tax purposes, will be taxable as dividend income. Distributions in excess of current and accumulated earnings and profits will be a tax-free recovery of basis to the extent of the holder’s adjusted tax basis in the shares, and any remaining amount of distributions will generally be subject to tax as capital gain. Dividends on RCI Non-Voting Shares will generally be foreign source income for foreign tax credit limitation purposes and not be eligible for a dividends received deduction.

Dividends paid in Canadian dollars will be includible in income in an amount equal to the United States dollar value of the dividends calculated by reference to the exchange rate in effect on the day the dividends are received, regardless of whether the dividends are converted into United States dollars. United States Holders generally should not recognize any foreign currency gain or loss if the Canadian dollars are converted into United States dollars on the day they are received. If, however, Canadian dollars are not converted into United States

dollars on the day they are received, any gain or loss resulting from currency exchange fluctuations from the date the dividends are includible in income to the date the payment is converted into United States dollars will be ordinary income or loss. Such currency gain or loss will generally be income or loss from United States sources for foreign tax credit limitation purposes.

Certain dividends received by United States individuals before January 1, 2009 from a qualified foreign corporation are subject to a maximum Federal income tax rate of 15%. A foreign corporation will generally be considered a qualified foreign corporation if it is eligible for the benefits of a comprehensive income tax treaty with the United States that contains an exchange of information program. The United States Treasury Department has identified the U.S. — Canada income tax treaty as a qualifying treaty. As a result, management believes that RCI is, and will continue to be, a qualified foreign corporation. To qualify for the reduced rate of taxation on dividends, a holder must satisfy certain holding period and other requirements with respect to its RCI Non-Voting Shares. United States Holders should consult their tax advisors concerning their eligibility for the reduced rate of Federal income tax on dividends on RCI Non-Voting Shares.

Dividends paid on the RCI Non-Voting Shares will generally be subject to Canadian withholding taxes. A United States Holder may be eligible to claim a credit or deduction for any Canadian withholding tax paid with respect to dividends from RCI. The calculation of foreign tax credits and deductions involves the application of complex rules and limitations that depend upon a holder’s particular circumstances. United States Holders should consult their own tax advisors regarding the availability of foreign tax credits and deductions for Canadian tax withheld.

Sale or Other Disposition of RCI Non-Voting Shares

Upon the sale or exchange (other than a conversion) of RCI Non-Voting Shares, a United States Holder will recognize gain or loss in an amount equal to the difference between (i) the holder’s adjusted tax basis of the RCI Non-Voting Shares and (ii) the sum of the cash and the fair market value of the property received. Such gain or loss generally will be treated as capital gain or loss, and as long-term capital gain or loss if the RCI Non-Voting Shares had been held more than one year at the time of disposition. For foreign tax credit limitation purposes, gain or loss recognized on a sale or exchange of RCI Non-Voting Shares will generally be United States source income or loss. Any gain or loss from currency exchange fluctuations between the date of the disposition of the RCI Non-Voting Shares and the conversion of the sales proceeds into United States dollars will be United States source ordinary income or loss.

Information Reporting and Backup Withholding

Payments of dividends on RCI Non-Voting Shares and the proceeds of the disposition of RCI Non-Voting Shares that are made within the United States or through certain U.S.-related financial intermediaries may be required to be reported to the Internal Revenue Service and may be subject to backup withholding unless (i) the holder is a corporation or other exempt recipient, or (ii) the holder provides a taxpayer identification number or complies with applicable certification requirements. Non-United States Holders are generally exempt from the information reporting and backup withholding rules but may be required to comply with certification requirements to prove their exemption. The backup withholding rate is currently 28%. Amounts withheld under the backup withholding rules will be allowed as a refund or credit against a holder’s United States Federal income tax liability if the required information is furnished to the Internal Revenue Service.

RISK FACTORS

The following risk factors should be considered by Shareholders in evaluating whether to approve the Arrangement Resolution. These risk factors should be considered in conjunction with the other information contained in or incorporated by reference into this Circular. These risk factors relate to the Arrangement. For information on risks and uncertainties relating to the business of RCI, reference should be made to management’s discussion and analysis of the audited consolidated financial statements of RCI as at and for the years ended December 31, 2004 and December 31, 2003, and management’s discussion and analysis of the unaudited interim consolidated financial statements of RCI as at March 31, 2005 and for the three months ended March 31, 2005 and March 31, 2004, together with the other documents filed by RCI with the securities commission or similar authority in each of the provinces of Canada and specifically incorporated by reference herein.

Because the market price of RCI Non-Voting Shares will fluctuate and the exchange ratio is fixed, Shareholders cannot be certain of the market value of the consideration they will receive for their Call-Net Shares under the Arrangement Agreement.

The exchange ratio is fixed and will not increase or decrease due to fluctuations in the market price of RCI Non-Voting Shares. The market price of RCI Non-Voting Shares or Call-Net Shares could each fluctuate significantly prior to the Effective Date in response to various factors and events, including the differences between RCI’s and Call-Net’s actual financial or operating results and those expected by investors and analysts, changes in analysts’ projections or recommendations, changes in general economic or market conditions, and broad market fluctuations. As a result of such fluctuations, historical market prices are not indicative of future market prices or the market value of the RCI Non-Voting Shares that holders of Call-Net Shares may receive on the Effective Date. There can be no assurance that the market value of the RCI Non-Voting Shares that the holders of Call-Net Shares may receive on the Effective Date will equal or exceed the market value of the Call-Net Shares held by such Shareholders prior to the Effective Date. Similarly, there can be no assurance that the trading price of RCI Non-Voting Shares will not decline following the completion of the Arrangement.

RCI and Call-Net may not integrate successfully.

The Arrangement will involve the integration of companies that previously operated independently. As a result, the combination will present challenges to management, including the integration of the operations, systems, technologies and personnel of the two companies, and special risks, including possible unanticipated liabilities, unanticipated costs, diversion of management’s attention, operational interruptions and the loss of key employees, customers or suppliers.

The difficulties RCI’s management encounters in the transition and integration processes could have an adverse effect on the revenues, level of expenses and operating results of the combined company. As a result of these factors, it is possible that RCI will not achieve anticipated cost reductions and synergies or that other benefits expected from the combination will not be realized.

Uncertainty surrounding the Arrangement could adversely affect Call-Net’s retention of customers, suppliers, strategic partners and personnel and could negatively impact Call-Net’s future business and operations.

Because the Arrangement is dependent upon receipt of certain regulatory approvals and satisfaction of certain conditions, its completion is subject to uncertainty. In response to this uncertainty, Call-Net’s customers, suppliers and strategic partners may delay or defer decisions concerning Call-Net. Any delay or deferral of those decisions by customers, suppliers or strategic partners could have a material adverse effect on the business and operations of Call-Net, regardless of whether the Arrangement is ultimately completed. Similarly, current and prospective employees of Call-Net may experience uncertainty about their future roles with RCI until RCI’s strategies with respect to Call-Net are announced and executed. This may adversely affect Call-Net’s ability to attract or retain key management, sales and marketing personnel in the period until the Arrangement is completed.

The Termination Fee provided under the Arrangement Agreement may discourage other parties from attempting to acquire Call-Net.

Under the Arrangement Agreement, Call-Net would be required to pay a Termination Fee of $10 million in the event the Arrangement Agreement is terminated in certain circumstances. This Termination Fee may discourage other parties from attempting to acquire Call-Net Shares, even if those parties would otherwise be willing to offer greater value to Shareholders than offered by RCI under the Arrangement.

INFORMATION RELATING TO RCI

Description of Share Capital

Preferred Shares

As of March 31, 2005, there were 400,000,000 authorized preferred shares of RCI without par value, issuable in series, with rights and terms of each series to be fixed by the board of directors of RCI prior to the issue of such series. RCI has three authorized series of preferred shares, being the Series XXVII Preferred Shares, Series XXX Preferred Shares and Series XXXI Preferred Shares. The Series XXVII Preferred Shares are non-voting, are redeemable at $1,000 per share at RCI’s option and carry the right to cumulative dividends at a rate equal to the bank prime rate plus 1³/4% per annum. The Series XXX Preferred Shares are non-voting, are redeemable at $1,000 per share at RCI’s option and carry the right to non-cumulative dividends at a rate of 9¹/2% per annum. The Series XXXI Preferred Shares are non-voting, are redeemable at $1,000 per share at RCI’s option and carry the right to cumulative dividends at a rate of 9⁵/8% per annum. There are no preferred shares of RCI outstanding.

RCI Non-Voting Shares and RCI Class A Voting Shares

As at May 1, 2005, there were 56,240,494 authorized RCI Class A Voting Shares without par value, of which 56,235,394 were issued and outstanding. Each RCI Class A Voting share is entitled to 50 votes per share. The holders of RCI Non-Voting Shares are entitled to receive notice of and to attend meetings of RCI’s shareholders but, except as required by law, are not entitled to vote at such meetings. The RCI Class A Voting Shares may receive a dividend at an annual rate of up to $0.05 per share only after the Non-Voting Shares have been paid a dividend at an annual rate of $0.05 per share. The RCI Class A Voting Shares are convertible on a one-for-one basis into Non-Voting Shares.

As at May 1, 2005, there were 1,400,000,000 authorized RCI Non-Voting Shares with a par value of $1.62478 per share, of which 220,472,685 were issued and outstanding. The RCI Class A Voting Shares and RCI Non-Voting Shares participate equally share for share in dividends after payment of an annual dividend of $0.05 per share for each class and participate equally share for share in any of RCI’s remaining assets in the event of RCI’s dissolution or winding up (subject to the preference as to dividends in favour of the RCI Non-Voting Shares).

In May 2003, RCI adopted a dividend policy that provides for the payment, each year, of dividends aggregating $0.10 per share to be payable twice yearly on each outstanding RCI Non-Voting share and RCI Class A Voting share held as of the record date, as determined by RCI’s board of directors.

Under applicable Canadian securities laws, an offer to purchase RCI Class A Voting Shares would not require that an offer be made to purchase RCI Non-Voting Shares.

RCI’s articles contain restrictions on the transfer, voting and issue of RCI Class A Voting Shares and RCI Non-Voting Shares in order to ensure that RCI remains qualified to hold or obtain licences required to carry on certain of RCI’s business undertakings in Canada. RCI is authorized to refuse to register transfers of any of its shares to any person who is not a Canadian in order to ensure that RCI remains qualified to hold the licences referred to above.

Restrictions on the Transfer, Voting and Issue of RCI Shares

RCI has a direct or indirect ownership interest in a number of distinct Canadian undertakings, which hold licences pursuant to applicable licencing legislation (the “Telecommunications Legislation”). The Telecommunications Legislation includes the Broadcasting Act (Canada), the Telecommunications Act (Canada) and the Radiocommunication Act (Canada).

The Telecommunications Legislation contains separate requirements relating to the level of foreign ownership that is permitted in respect of a given class of licenced undertaking. RCI believes that it, and each of its subsidiaries, have at all times been in compliance with all of the relevant ownership requirements of the Telecommunications Legislation.

In April 1996, the Governor in Council (i.e., the federal cabinet) issued a Direction to the CRTC respecting the ineligibility of non-Canadians to hold broadcasting licences, including licences to operate cable television undertakings. That Direction substantially harmonized the foreign ownership requirements under the Broadcasting Act (Canada) with those under the Telecommunications Act (Canada) and the Radiocommunication Act (Canada). The Direction was amended in 1997 to allow two non-Canadian controlled telephone companies to hold licences to operate cable television undertakings within their respective service areas. It was amended in July 1998 to clarify the restrictions relating to a holding company’s ability to control or influence the programming decisions of the licencee operating company.

The revised Cabinet Direction authorizes non-Canadians to own and control, directly or indirectly, up to 33¹/3% of the voting shares and up to 33¹/3% of the number of votes attached to the voting shares of a holding company which has a subsidiary operating company licenced under the Broadcasting Act (Canada). In addition, up to 20% of the voting shares and up to 20% of the votes attached to the voting shares of the operating licencee company may be owned and controlled, directly or indirectly, by non-Canadians. The chief executive officer and 80% of the members of the board of directors of the operating licencee company must be Canadian. In addition, the holding company and its directors are prohibited from exercising control or influence over the programming decisions of the licencee company, unless the holding company satisfies the ownership requirements which are applicable to the licencee company. There are no restrictions on the number of non-voting shares that may be held by non-Canadians at either the holding company or licencee company level. The CRTC retains the discretion under the Direction to determine whether a given licencee is in fact controlled by non-Canadians.

The cellular, PCS and paging licences held by RCI include a condition requiring the licenced carrier company to comply with the ownership restrictions set out in the Telecommunications Act (Canada) and the Radiocommunication Act (Canada). A maximum level of 20% of the issued voting shares of the licenced carrier company may be owned by persons who are not Canadians. In addition, at least 80% of the members of the board of directors of the licenced carrier company must be Canadian. Pursuant to regulations promulgated under the Telecommunications Act (Canada) and the Radiocommunication Act (Canada), a parent corporation may have up to 33¹/3% of its voting shares owned by non-Canadians. Neither the licenced carrier company nor the parent holding corporation can be otherwise controlled by non-Canadians.

In order to ensure that RCI and any Canadian corporation in which RCI has a direct or indirect interest remains qualified to hold or obtain any cable television, broadcasting or telecommunications licence or authority to operate a similar undertaking pursuant to the Telecommunications Legislation and to ensure that RCI and any Canadian corporation in which RCI has an interest is not in breach of the Telecommunications Legislation or any licences issued to it or to any Canadian subsidiary, associate or affiliate of it under the Telecommunications Legislation, the articles of RCI impose certain restrictions on the issue and transfer of RCI’s shares and the exercise of voting rights attached thereto. A copy of the text of such restrictions may be obtained from the Secretary of RCI.

If in the opinion of the board of directors of RCI circumstances arise in the future that may jeopardize the ability of RCI and its subsidiaries to be qualified to hold and obtain licences in Canada, the restrictions on transfer, voting and issue of shares contained in the articles of RCI will be invoked.

On November 19, 2002, the Minister of Industry announced that the Government of Canada will review the restrictions on foreign ownership applicable to the telecommunications sector. In February 2003, RCI appeared before the Parliamentary Standing Committee on Industry, Science and Technology and filed a brief in support of elimination of the restrictions. A similar submission had been made by RCI in February of 2002 to the Standing Committee on Canadian Heritage urging the removal of restrictions on foreign ownership applicable to cable television companies. In April 2003, the House of Commons Industry Committee released a report calling for the removal of foreign ownership restrictions for telecommunications carriers and broadcasting distribution undertakings. In June 2003, the House of Commons Heritage Committee released a report opposing the Industry Committee’s recommendation. The Cabinet responded to the Industry Committee report in September 2003 and to the Heritage Committee report in November 2003. The government announced that officials from the Heritage and Industry departments will convene to reconcile the two positions. The Heritage Department released a report on April 5, 2005, which stated that “the Government wishes to indicate that it is not prepared to modify foreign ownership limits on broadcasting or content more generally.” Industry Canada is convening a panel of experts to examine the telecommunications regulatory regime. This panel may review the foreign ownership rules applicable to telecommunications.

RECENT INDUSTRY DEVELOPMENTS

The following is a description of certain recent industry developments, which affect both RCI and Call-Net:

On April 11, 2005, Minister of Industry, David Emerson, announced the creation of the Telecom Policy Review Panel, composed of three eminent Canadians, to review Canadian telecommunications policy and report back to the Minister by the end of December 2005 with recommendations for ensuring that Canada maintains a modern telecommunications policy suitable to support Canada’s competitiveness in the 21st Century. The terms of reference for the policy review indicate that the Government is concerned with Canada’s regulatory regime, promotion of broadband access and fostering ICT (information, communications and technology) adoption.

On April 27, 2005, the CRTC issued Telecom Decision CRTC 2005-25, Promotions of local wireline services, in which it permitted ILEC promotions in the local wireline market, subject to a number of competitive safeguards. In so doing, the CRTC lifted a two-year long suspension of these promotions. The competitive safeguards imposed on ILEC promotions provide some protection against the detrimental effect such promotions can have on competitors. These safeguards require, among other things, that promotions be available and equally promoted across one or more entire rate bands, that promotions must not be limited to customers of competitors (i.e., they must not be winback promotions), that promotions must pass the price floor test and that the combined enrolment and benefit period of a promotion cannot exceed six consecutive months. These safeguards will help to ensure that the potential for anti-competitive abuses of the ILECs’ ability to engage in promotions in the local wireline market will be mitigated.

On April 28, 2005, the CRTC issued Telecom Public Notice CRTC 2005-2, Forbearance from regulation of local exchange services. In this public notice, the CRTC has initiated a proceeding and invited comments on a framework for forbearance from the regulation of residential and business local exchange services. The CRTC also requests comment on the appropriateness of a transitional regime that could provide ILECs with more regulatory flexibility prior to forbearance through the lessening or removing of competitive safeguards. The CRTC also requests comments on an application for forbearance from regulation of residential wireline local services filed by Aliant Telecom Inc. The CRTC indicated in this public notice that it expected to issue a decision clarifying the criteria to be applied by it in determining whether to forbear from regulating the ILECs’ local service in April 2006. The CRTC indicated that it contemplates that the ILECs (with the exception of Aliant, whose application for forbearance will be considered in the present proceeding) would be able to apply for forbearance only after the CRTC’s decision in this present proceeding is issued. As well, given the comments contained in its VoIP decision, referred to below, it is clear that the CRTC believes it is currently premature to forbear from regulating the ILECs’ local exchange services.

On April 29, 2005, the CRTC issued Telecom Decision CRTC 2005-27, Review of price floor safeguards for retail tariffed services and related issues, its decision in the proceeding commenced by way of Telecom Public Notice CRTC 2003-10. In this decision, the CRTC rejected an application by RCI to prohibit the ILECs from bundling local telephone services with competitive services. The CRTC also rejected their own proposals to put limits on the bundling of local and competitive services. The decision did confirm that any rate reductions for local services or any bundles containing local services must be offered throughout an entire service Band as defined by the CRTC. In this decision, the CRTC modified the imputation test (i.e., the price floor established to ensure the ILECs cannot price regulated services in an anti-competitive manner) to require ILECs to “impute” the rate that competitors like Call-Net have to pay for certain services (Category 1 Services), and not just the ILECs’ own cost of these services. Similarly, the decision requires the ILECs to impute the applicable tariffed rates for residential local exchange services where these are offered in a bundle. This enhances the protection available to competitors from price-squeezes and other anti-competitive actions. The decision also restated the definition of a tariffable bundle, thereby confirming that ILECs must obtain prior approval from the CRTC for a broader variety of bundles that include regulated services.

On May 12, 2005, the CRTC issued Telecom Decision CRTC 2005-28, Regulatory framework for voice communication services using Internet Protocol, its decision in the proceeding commenced by way of Telecom Public Notice CRTC 2004-2. In this decision, the CRTC established the rules applicable to the provision of voice over IP (“VoIP”) services. The CRTC found that VoIP services that permitted users to make local calls over the public-switched telephone network (“PSTN”) were a close substitute for traditional, circuit-switched local

telephone service and accordingly should be generally regulated pursuant to the same rules. The CRTC denied the requests of most of the large ILECs that the CRTC forbear from the provisions of the Telecommunications Act requiring them to file tariffs for the prior approval of their rates for local VoIP services and from other regulatory obligations imposed under the Act, finding that the large ILECs had substantial market power in the relevant market, which included traditional local phone service. Call-Net and RCI believe that this decision should help to prevent the large ILECs such as Bell and Telus from pricing their VoIP services at below their costs as an anti-competitive tactic. By contrast, as non-dominant carriers, Call-Net and RCI and their respective subsidiaries are able to provide local VoIP subject to the more flexible regulatory regime that is imposed on new entrants in the local phone market.

INFORMATION RELATING TO CALL-NET

The following information about Call-Net is only a general summary and is not intended to be comprehensive. For additional information about Call-Net, you should refer to the information described under “— Call-Net Documents Incorporated by Reference”.

Call-Net

Call-Net, with its head office at 2235 Sheppard Avenue East, Atria II, Suite 1800, Toronto, Ontario M2J 5G1, is a holding company that conducts its telecommunications business primarily through its wholly-owned operating subsidiaries: Call-Net Communications Inc., Call-Net Technology Services Inc., Sprint Canada Inc., AlternaCall Inc., and CNCS Inc. Call-Net owns and operates an extensive national fibre network and maintains network facilities in the United States and the United Kingdom. It also has switching centres in Vancouver, Calgary, Toronto and Montreal, and call centres in Montreal and Toronto. Call-Net operates a local services network in 33 municipalities through 151 ILEC switch co-location sites in five major urban areas. Call-Net has approximately 1,800 employees.

services to Canadian businesses and all levels of government. Call-Net estimates that it has approximately 3.3% of the Canadian long distance, data and local services markets and 2.4% of the total Canadian telecommunications market.

Recent Developments

On May 2, 2005 Call-Net announced that it has entered into an agreement with Bell Canada to purchase certain local and inter-exchange carrier network assets in New Brunswick and Nova Scotia and to purchase an option on certain other CLEC (competitive local exchange carrier) network assets in Eastern Canada. The transaction is part of Call-Net’s acquisition of the 360networks Corporation (360/GT) customer base in Eastern Canada from Bell Canada, announced in November of 2004. The agreement contemplates that Call-Net will purchase virtually all of the former Group Telecom’s network assets in New Brunswick and Nova Scotia including long-haul (inter-city) and access (intra-city) fibre, together with switching and network equipment from Bell Canada. The agreement also contemplates that Call-Net will acquire from Bell Canada an option to purchase over 90 per cent of the remaining CLEC network of former Group Telecom in the provinces of Ontario, Quebec, and Newfoundland and Labrador.

The completion of the transaction is subject to the negotiation, execution and delivery of definitive agreements setting forth the terms of the transaction; the completion of all required regulatory filings; all necessary consents, approvals and advance rulings; the satisfactory completion of Call-Net’s due diligence; and, if required, the approval of the transaction and the definitive agreements by the board of directors of each of Call-Net and Bell Canada.

Description of Capital Structure

The authorized share capital of Call-Net consists of Common Shares, Non-Voting Shares and Preferred Shares. The following summary describes the rights, privileges, restrictions and conditions that attach to the Common Shares, the Non-Voting Shares and the Preferred Shares.

Common Shares

Call-Net is authorized to issue an unlimited number of its Common Shares. The holders of the Common Shares are entitled to one vote for each share held at any meeting of the Shareholders. The Common Shares are convertible, at the option of the Shareholders, at any time into Non-Voting Shares on a share-for-share basis. The Common Shares rank pari passu with the Non-Voting Shares on a per share basis with respect to payment of dividends and the right to participate in a distribution of assets of Call-Net on winding up, dissolution or otherwise.

Non-Voting Shares

Call-Net is authorized to issue an unlimited number of Non-Voting Shares. The holders of the Non-Voting Shares are not entitled to vote at any meeting of Shareholders except for votes affecting the Non-Voting Shares. The Non-Voting Shares are convertible, at the option of the holders thereof, at any time into Common Shares on a share-for-share basis, in the following circumstances: (a) upon the provision by a Shareholder of a Residency Declaration to Call-Net and CIBC Mellon stating that the holder is a Canadian (as such term is defined in the Telecommunications Act (Canada)); (b) upon the Board of Directors, by resolution, allowing the conversion, from time to time, of such number of Non-Voting Shares as will not, in the sole discretion of the Board of Directors, place Call-Net at risk of non-compliance with the foreign ownership restrictions of the Telecommunications Act, provided that such conversion right is made available on a pro rata basis to all holders of Non-Voting Shares; (c) upon a take-over bid being made for the Common Shares for the purposes of allowing the Non-Voting Shares to tender to such bid; or (d) without restriction, upon the foreign ownership restrictions in the Telecommunications Act (Canada) being removed to the satisfaction of the Board of Directors. For the purposes of paragraph (b), the Board of Directors shall consider at least once in each calendar year whether to allow such conversion. Notwithstanding the foregoing, the Board of Directors shall only allow for such conversion if, at the time of conversion, at least 1% of the then outstanding Non-Voting Shares can be converted. The Non-Voting Shares rank

pari passu with the Common Shares on a per share basis with respect to the payment of dividends and the right to participate in a winding up, dissolution or otherwise.

Preferred Shares

Call-Net is authorized to issue an unlimited number of the Preferred Shares. As part of the consideration for entering into the Sprint Agreement, Sprint was issued the Call-Net Preferred Share (for a value of $1.00) and is the first and only holder of Preferred Shares at December 31, 2004. The Preferred Shares are generally non-voting, except (i) as a class pursuant to any rights granted under the CBCA, (ii) as a class in respect of amendments to the minimum or maximum number of directors and (iii) with respect to the election of two directors. The Preferred Shares entitle the holder to nominate and elect two directors of Call-Net. The Preferred Shares have no rights to dividends. The Preferred Shares have a priority right over all other classes of shares to receive a return of capital equal to $1.00 per Preferred Share upon the liquidation, dissolution or winding up of Call-Net. Call-Net may redeem all Preferred Shares for $1.00 per Preferred Share upon the sale, transfer or assignment of the Preferred Shares by the first holder to a third party that is not an affiliate of the first holder or the subsequent transfer by such affiliate, or any other affiliate of the first holder who from time to time holds the Preferred Shares, to a non-affiliate of the first holder, or upon any affiliate of the first holder who holds the Preferred Shares no longer being an affiliate of the first holder, or in the event that the Sprint Agreement is terminated. “Terminated” for this purpose, means terminated for a reason other than the default of Call-Net, and where the termination of the agreement has been disputed by either party, the Sprint Agreement shall be deemed not to have been terminated until the parties agree that such termination shall have occurred or until the dispute has been resolved through a final, non-appealable decision.

Constraints

Compliance with the Telecommunications Act (Canada)

To ensure compliance with the foreign ownership restrictions contained in the Telecommunications Act (Canada), for so long as the Telecommunications Act (Canada) applies to Call-Net, Call-Net has the right, in addition to any other rights under the Telecommunications Act (Canada), to sell the Common Shares of a Shareholder who is not a Canadian (as such term is defined in the Telecommunications Act (Canada)), subject to the provisions of the CBCA and the Telecommunications Act (Canada). In addition, the directors of Call-Net may refuse to issue a Common Share, or register the transfer of a Common Share, in a circumstance where to do so otherwise would result in Call-Net’s non-compliance with the foreign ownership restrictions of the Telecommunications Act (Canada).

Dividends

Under the Indenture governing the Secured Notes, there are certain limitations and restrictions on the payment of dividends and corporate distributions. Call-Net has never paid dividends on any of its issued shares and does not currently contemplate paying dividends on any of its issued shares.

Call-Net Rights Plan

Call-Net has established the Call-Net Rights Plan to ensure, to the extent possible, that all shareholders will be treated equally and fairly in connection with any take-over bid for Call-Net. The Call-Net Rights Plan is designed to prevent the use of coercive and/or abusive takeover techniques and to encourage a potential acquiror to negotiate directly with the Board of Directors for the benefit of all shareholders. In addition, the Call-Net Rights Plan is intended to provide increased assurance that a potential acquiror would pay an appropriate control premium in connection with any acquisition of Call-Net. Nevertheless, the Call-Net Rights Plan could be utilized, under certain circumstances, as a method of discouraging, delaying or preventing a change of control.

The Call-Net Rights Plan is triggered when a person acquires beneficial ownership of (i) 20% or more of the Common Shares, or (ii) 20% of the aggregate Call-Net Shares, other than under certain conditions. The purpose of the Call-Net Rights Plan is to provide the Board of Directors with time to review any unsolicited take-over bid that may be made and to take action, if appropriate, to enhance shareholder value. The Call-Net Rights Plan

attempts to protect shareholders by requiring all potential bidders to comply with the conditions specified in the Call-Net Rights Plan, failing which such bidders are subject to the dilutive features of the Call-Net Rights Plan. By creating the potential for substantial dilution of a bidder’s position, the Call-Net Rights Plan encourages an offeror to proceed by way of the permitted bid mechanism set forth in the Call-Net Rights Plan or to approach the Board of Directors with a view to a negotiation. Under the Arrangement, the Call-Net Rights Plan will be deemed to have been terminated (and all rights thereunder shall expire) immediately prior to the Effective Time, at which time the Rights Plan will no longer be necessary to protect the interests of Shareholders.

EFFECT OF THE ARRANGEMENT ON MARKETS AND LISTINGS

If the Arrangement is completed, the Call-Net Shares will be de-listed from the TSX.

COMPARISON OF RIGHTS UNDER CBCA AND BUSINESS CORPORATIONS ACT

(BRITISH COLUMBIA)

RCI is governed by the British Columbia Business Corporations Act (“BCA”). Call-Net is governed by the CBCA. The BCA was brought into force on March 29, 2004 and replaces the British Columbia Company Act. The BCA retains the contract model of incorporation and has not adopted the CBCA model. The following is a summary of certain differences between the BCA and the CBCA, which management considers to be of significance to Shareholders. The summary is not an exhaustive review of the two statutes. Reference should be made to the full text of both statutes and the regulations thereunder for particulars of any differences between them, and Shareholders should consult their legal or other professional advisors with regard to the implications of the Arrangement that may be of importance to them.


	1.	Registered Office. Under the BCA, the registered office of the corporation must be situated in British Columbia; under the CBCA, the registered office of the corporation may be situated in the province in Canada specified in its articles of incorporation.

	2.	Shareholders’ Meetings. Under the BCA, shareholders’ meetings must be held in British Columbia unless the articles (which are the equivalent to by-laws under the CBCA) provide that the meeting may be held in a location outside of British Columbia, or the other location is approved by the shareholders or by the British Columbia Registrar; under the CBCA, shareholders’ meetings may be held at a place in Canada provided for in the bylaws or, in the absence of such provision, at the place within Canada that the directors determine, and shareholders’ meetings may be held at a place outside Canada if the place is specified in the articles of incorporation or if all shareholders entitled to attend consent.


	3.	Special Resolutions. Under the BCA, a special majority is the majority of votes required for a special resolution and the special majority must be specified to be not less than a two-thirds majority and not more than a three-quarters majority of the votes cast on the resolution and, if no specification is made, the default majority is two-thirds. (For British Columbia companies incorporated under the previous British Columbia Company Act, the default majority is a three-quarters majority until amended by special resolution.) Under the CBCA, a special resolution is a resolution passed by a majority of not less than two-thirds of the votes cast by shareholders who vote in respect of that resolution or a resolution signed by all of the shareholders entitled to vote on that resolution.

	4.	Director Residency Requirements. Under the BCA, there are no director residency requirements; under the CBCA, 25% of the directors must be resident Canadians or, if the corporation has fewer than four directors, at least one director must be resident Canadian. In certain situations, such as when the CBCA corporation is engaged in a prescribed business sector, a majority of the directors must be resident Canadians.

	5.	Short Form Amalgamations. Both the BCA and CBCA permit short form amalgamations, where a parent corporation and one or more wholly-owned subsidiaries amalgamate or where two or more wholly-owned subsidiaries of the same parent corporation amalgamate. For short form amalgamations under the BCA, amalgamated corporations may elect to obtain court approval; under the CBCA, amalgamating corporations are not required to seek court approval.

	6.	Subsidiary Holding share of Parent. Under the BCA, subject to certain solvency tests, a subsidiary is permitted to hold and acquire shares in its parent. Shares of a parent held by a subsidiary, however, may not be voted; under the CBCA, except in limited circumstances, a corporation may not hold shares in its parent nor allow any of its subsidiaries to acquire shares of its parent.

	7.	Removal of Directors. Under the BCA, a director may be removed by special resolution or, if the memorandum or articles provide that a director may be removed by a resolution of the shareholders entitled to vote at general meetings passed by less than a special majority or may be removed by some other method, by the resolution or method specified, including ordinary resolution or directors’ resolution; under the CBCA, a director may be removed by ordinary resolution.

	8.	Reliance by Directors. Under the BCA, directors will not be found liable if they rely in good faith on financial statements, auditor’s reports, professional reports, statements of fact from an officer or any other document which the court considers as a reasonable ground for the director’s conduct; under the CBCA, directors may rely on financial statements, auditor’s reports and professional reports; however, the court is not granted the same jurisdiction in determining whether a director’s reliance upon other documents is acceptable.

	9.	Transfer Restrictions on Shares. Under the BCA, corporations are free to impose restrictions on the transfer of their shares as long as those restrictions are set out in their articles of incorporation; under the CBCA, the ability of a corporation to restrict the transfer of its shares is subject to greater restrictions.

	10.	Insolvency. Under the BCA, the determination of insolvency is subject to the ability of a corporation to meet its liabilities as they become due; under the CBCA, the test is similar to the one under the BCA, however, it imposes a further requirement that the realizable value of the corporation’s assets would need to exceed the aggregate of its liabilities and stated capital of all classes of shares.

	11.	Reduction in Capital. Under the BCA, the reduction of a corporation’s capital may be authorized by a special resolution, unless the reduction in capital would result in a lower realizable asset value than the total of all liabilities, in which case a corporation would require a court order to proceed with the capital reduction; under the CBCA, a corporation would similarly need to show that its realizable asset value was greater than its liabilities; however, unlike the BCA, a corporation may not apply to the courts for discretionary relief in allowing the reduction should the financial tests not be met.


	12.	Sale of Assets. Under the BCA, the sale of all or substantially all of a corporation’s assets is exempt from the requirement that the disposition be in the normal course of business or approved by special resolution when the disposition is by way of security interest, by way of a lease (if the term of the lease, at its beginning, does not exceed three years, and any option or covenant for renewal included in the lease is not capable of extending the total lease periods beyond three years) or if a corporation is making the disposition to a non-arm’s length or affiliated entity; under the CBCA, there are no exemptions from the normal course of business or special resolution requirement when effecting the sale of all or substantially all of a corporation’s assets.

	13.	Dissent Rights. Under the BCA, shareholders are permitted to exercise dissent rights in respect of certain fundamental corporate actions, although the court retains the discretion to vary the statutory framework of the dissent proceedings. Additionally, shareholders may waive dissent rights with respect to a particular charge; however, dissent rights may not be waived all together; under the CBCA, there are no provisions to allow the court to vary the statutory framework of the proceedings or to allow shareholders to waive dissent rights under a particular charge.

	14.	Oppression Actions. Under the BCA, an eligible applicant (the courts reserve a discretion to determine the scope of potential claimants) may apply to the court for a remedy from oppressive acts of the corporation. The applicant must show that the corporate acts were either oppressive or unfairly prejudicial; under the CBCA, the ability of an applicant to successfully launch an action is somewhat more broad, as an action may be founded on the basis of oppression, unfair prejudice or an unfair disregard of applicant’s interests.

	15.	Appointment of Inspector. Under the BCA, an inspector may be appointed either by special resolution or on application to the court by shareholders holding at least 20% of the outstanding shares; under the CBCA, an investigator may only be appointed by an application to the courts. Such an application, however, may be made by any shareholder of the corporation regardless of the number of shares owned.

	16.	Par Value of Shares. Under the BCA, the share capital in a corporation may consist of either par value or no par value shares; under the CBCA, shares with par value are prohibited.

	17.	Corporation Holding its Own Shares. Under the BCA, a corporation is expressly permitted to hold its own shares, which in effect allows the corporation the choice to either cancel the shares so held or allow the shares to remain outstanding; the CBCA, except in very limited circumstances, does not allow a corporation to hold its own shares.

	18.	Choice of Authorizing Resolution. Unlike the CBCA, the BCA permits a company to select the kind of resolution that will govern certain corporate acts. The most obvious examples of “corporate choice” arise in the case of alterations to the charter documents of the company (notice of articles and articles). The articles may permit alterations to the notice of articles or the articles to be authorized by way of a directors’ resolution (except that a special resolution is required, in the absence of a provision in the articles permitting a shareholders’ resolution, to alter the special rights and restrictions attached to a class of shares if the shares of that class have already been issued) or by several different types of shareholders’ resolutions. The latter include an ordinary resolution (the majority at a meeting is a simple majority), a special resolution (the majority is a “special majority”; a company may, under its articles, set a special majority at any threshold between ²/3 and ³/4 of the votes cast, failing which a special majority is defined under the new Act to be ²/3 of the votes cast), and a resolution with a higher majority than a special majority (an “exceptional resolution”). If silent, the default is usually a special resolution. In another example of corporate choice, directors can be removed by a special resolution, but can also be removed by a shareholders’ resolution specified in the articles with a majority less than a special majority, or even by a directors’ resolution, if so specified in the articles.

RIGHTS OF DISSENTING SHAREHOLDERS

The Interim Order expressly provides registered holders of Call-Net Shares with the right to dissent with respect to the Arrangement. As a result, any Dissenting Shareholder is entitled to be paid the fair value (determined as at the close of business on the second business day before the Arrangement Resolution is adopted) of all, but not less than all, of the shares of the same class beneficially held by it in accordance with section 190 of the CBCA, if the shareholder dissents with respect to the Arrangement and the Arrangement becomes effective. If the registered holders of more than 10% of the issued and outstanding Call-Net Shares dissent, RCI may elect to terminate the Arrangement Agreement.

Section 190 of the CBCA provides that a shareholder may only make a claim under that section with respect to all of the shares of a class held by the shareholder on behalf of any one beneficial owner and registered in the shareholder’s name. One consequence of this provision is that a registered Shareholder may only exercise the dissent rights under section 190 of the CBCA (as modified by the Plan of Arrangement and the Interim Order) in respect of Call-Net Shares that are registered in that Shareholder’s name.

In many cases, Call-Net Shares beneficially owned by a holder (a “Non-Registered Holder”) are registered either (a) in the name of an intermediary (“Intermediary”) that the Non-Registered Holder deals with in respect of such shares, such as, among others, banks, trust companies, securities brokers, trustees and other similar entities, or (b) in the name of a depository (“Depository”), such as The Canadian Depository for Securities Limited (“CDS”), of which the Intermediary is a participant. Accordingly, a Non-Registered Holder will not be entitled to exercise his or her rights of dissent directly (unless the shares are re-registered in the Non-Registered Holder’s name). A Non-Registered Holder who wishes to exercise rights of dissent should immediately contact the Intermediary with whom the Non-Registered Holder deals in respect of its Call-Net Shares and either (i) instruct the Intermediary to exercise the rights of dissent on the Non-Registered Holder’s behalf (which, if the Call-Net Shares are registered in the name of CDS or any other clearing agency, may require that such Call-Net Shares first be re-registered in the name of the Intermediary), or (ii) instruct the Intermediary to re-register such Call-Net Shares in the name of the Non-Registered Holder, in which case the Non-Registered Holder would have to exercise the rights of dissent directly.

The execution or exercise of a proxy does not constitute a written objection for purposes of the rights to dissent under the CBCA.

The following summary does not purport to provide comprehensive statements of the procedures to be followed by a Dissenting Shareholder under the CBCA and section 190 of the CBCA is set forth in its entirety in Appendix F.

The CBCA requires adherence to the procedures established therein and failure to adhere to such procedures may result in the loss of all rights of dissent. Accordingly, each Shareholder who might desire to exercise rights of dissent should carefully consider and comply with the provisions of section 190 of the CBCA and consult its legal advisors.

Notwithstanding subsection 190(5) of the CBCA (pursuant to which a dissent notice may be provided at or prior to the Meeting), a Dissenting Shareholder who seeks payment of the fair value of its Call-Net Shares is required to deliver a written objection to the Arrangement Resolution to Call-Net by 5:00 p.m. (Toronto time) on the second business day preceding the Meeting. Call-Net’s address for such purpose is 2235 Sheppard Avenue East, Suite 1800, Atria II, Toronto, Ontario M2J 5G1. A vote against the Arrangement Resolution or a withholding of votes does not constitute a written objection. Within 10 days after the Arrangement Resolution is approved by the Shareholders, Call-Net must so notify the Dissenting Shareholder who is then required, within 20 days after receipt of such notice (or if such Shareholder does not receive such notice within 20 days after learning of the approval of the Arrangement Resolution), to send to Call-Net a written notice containing its name and address, the number and class of shares in respect of which the Shareholder dissents and a demand for payment of the fair value of such shares and, within 30 days after sending such written notice, to send to Call-Net or its transfer agent the appropriate share certificate or certificates.

A Dissenting Shareholder who fails to send to Call-Net, within the appropriate time frame, a dissent notice, demand for payment and certificates representing the shares in respect of which the shareholder dissents forfeits

the right to make a claim under section 190 of the CBCA. The transfer agent of Call-Net will endorse on the share certificates received from a Dissenting Shareholder a notice that the holder is a Dissenting Shareholder and will forthwith return the certificates to the Dissenting Shareholder.

On sending a demand for payment to Call-Net, a Dissenting Shareholder ceases to have any rights as a shareholder other than the right to be paid the fair value of such holder’s shares as determined under section 190 of the CBCA, except where:


	(a)	the Dissenting Shareholder withdraws the demand for payment before Call-Net makes an offer to the Shareholder pursuant to the CBCA,

	(b)	Call-Net fails to make an offer as hereinafter described and the Dissenting Shareholder withdraws the demand for payment, or

	(c)	the proposal contemplated in the Arrangement Resolution does not proceed,

in which case the rights as a shareholder of Call-Net will be reinstated as of the date the Dissenting Shareholder sent the demand for payment.

Shareholders who duly exercise their dissent rights and who:


	(a)	are ultimately entitled to be paid fair value for their Call-Net Shares shall be deemed to have transferred such Call-Net Shares to Call-Net for cancellation at the Effective Time; or

	(b)	for any reason are ultimately not entitled to be paid fair value for their Call-Net Shares shall be deemed to have participated in the Arrangement on the same basis as any non-Dissenting Shareholders as, at and from the Effective Time, and subject to Article 4 of the Plan of Arrangement, shall receive the RCI Non-Voting Shares in accordance with Article 2 of the Plan of Arrangement;

but, for greater certainty, in no case shall Call-Net, Call-Net Acquisition Company or RCI be required to recognize Dissenting Shareholders as Shareholders at and after the Effective Time, and the names of Dissenting Shareholders shall be deleted from the register of Shareholders as of the Effective Time.

If the Plan of Arrangement becomes effective, Call-Net will be required to send, not later than the seventh day after the later of (i) the Effective Date or (ii) the day the demand for payment is received, to each Dissenting Shareholder whose demand for payment has been received, a written offer to pay for such Dissenting Shareholder’s shares such amount as the Board of Directors considers fair value thereof accompanied by a statement showing how the fair value was determined.

Call-Net must pay for the shares of a Dissenting Shareholder within ten days after an offer made as described above has been accepted by a Dissenting Shareholder, but any such offer lapses if Call-Net does not receive an acceptance thereof within 30 days after such offer has been made.

If such offer is not made or accepted, Call-Net may, within 50 days after the Effective Date or within such further period as a court may allow, apply to a court of competent jurisdiction to fix the fair value of such shares. There is no obligation of Call-Net to apply to the court. If Call-Net fails to make such an application, a Dissenting Shareholder has the right to so apply within a further 20 days. A Dissenting Shareholder is not required to give security for costs in such an application.

Upon an application to a court, all Dissenting Shareholders whose Call-Net Shares have not been purchased by Call-Net will be joined as parties and be bound by the decision of the court, and Call-Net will be required to notify each Dissenting Shareholder of the date, place and consequences of the application and of the right to appear and be heard in person or by counsel. Upon any such application to a court, the court may determine whether any person is a Dissenting Shareholder who should be joined as a party, and the court will then fix a fair value for the shares of all Dissenting Shareholders who have not accepted an offer to pay. The final order of a court will be rendered against Call-Net in favour of each Dissenting Shareholder and for the amount of the Shareholder’s shares as fixed by the court. The court may, in its discretion, allow a reasonable rate of interest on the amount payable to each such Dissenting Shareholder from the Effective Date until the date of payment.

Registered Shareholders who are considering exercising dissent rights should be aware that there can be no assurance that the fair value of their shares as determined under the applicable provisions of the CBCA (as modified by the Plan of Arrangement and the Interim Order) will be more than or equal to the consideration offered under the Arrangement. In addition, any judicial determination of fair value will result in delay of receipt by a Dissenting Shareholder of consideration for such shareholder’s Call-Net Shares.

Under the CBCA, the Court may make any order in respect of the Arrangement it thinks fit, including a Final Order that amends the dissent rights as provided for in the Plan of Arrangement and the Interim Order. In any case, it is not anticipated that additional Shareholder approval would be sought for any such variation.

The foregoing summary does not purport to provide a comprehensive statement of the procedures to be followed by a Dissenting Shareholder who seeks payment of fair value of the Dissenting Shareholder’s Call-Net Shares. Section 190 of the CBCA requires strict adherence to the procedures established therein and failure to do so may result in a loss of a Dissenting Shareholder’s dissent rights. Accordingly, each Dissenting Shareholder who desires to exercise dissent rights should carefully consider and comply with the provisions of that section, the full text of which is set out in Appendix F to this Circular, as modified by the Interim Order, or should consult with such Dissenting Shareholder’s legal advisor.

LEGAL MATTERS

Legal matters in relation to the Arrangement will be reviewed and passed upon by Goodmans LLP on behalf of Call-Net and by Fasken Martineau DuMoulin LLP on behalf of RCI. As at the date of this Circular, partners and associates of Goodmans LLP own beneficially, directly or indirectly, less than 1% of the outstanding securities of Call-Net, RCI and their respective associates and affiliates. As at the date of this Circular, partners and associates of Fasken Martineau DuMoulin LLP own beneficially, directly or indirectly, less than 1% of the outstanding securities of Call-Net, RCI and their respective associates and affiliates. H. Garfield Emerson, Q.C., a partner of Fasken Martineau DuMoulin LLP, is the Chairman of the board of directors of RCI. U.S. legal matters in relation to the Arrangement will be reviewed and passed upon by Akin Gump Strauss Hauer & Feld LLP on behalf of Call-Net and by Cravath, Swaine & Moore LLP on behalf of RCI.

PARTICULARS OF OTHER MATTERS

Management knows of no matters to come before the Meeting other than the matters referred to in the Notice of Meeting. However, if any other matters that are not now known to management should properly come before the Meeting, the proxy (unless amended) will be voted upon such matters in accordance with the best judgment of the person voting the proxy.

GENERAL PROXY MATTERS

Solicitation of Proxies

The enclosed proxy is being solicited by or on behalf of the management of Call-Net and the cost of such solicitation will be borne by Call-Net. The solicitation will be primarily by mail, but directors, officers, employees and agents of Call-Net may also solicit proxies by telephone or in person. Georgeson Shareholder Communications Canada Inc. was retained by Call-Net to solicit proxies on behalf of Call-Net for a fee of $80,000 plus reasonable expenses, which fee is contingent, in part, on Shareholder approval of the Arrangement Resolution.

Appointment of Proxyholder

The persons named in the attached form of proxy are directors or officers of Call-Net. A holder of Call-Net Shares has the right to appoint as his or her proxyholder a person (who need not be a Shareholder) to attend and to act on his or her behalf at the Meeting other than the persons designated in

the form of proxy accompanying this Circular. A Shareholder may do so by inserting the name of such other person in the blank space provided in the applicable proxy or by completing another proper form of proxy and, in either case, by delivering the completed proxy to Call-Net’s registrar and transfer agent, CIBC Mellon. For postal delivery, the completed proxy should be mailed by using the envelope as provided. To deliver by facsimile, please send the proxy to the Proxy Department of CIBC Mellon at (416) 368-2502. The completed proxy may also be delivered in person to CIBC Mellon at 320 Bay Street, 6th Floor, Toronto, Ontario, M5H 4A6. Proxies delivered to CIBC Mellon must be received by not later than 5:00 p.m. (Toronto time) on the second business day preceding the Meeting, or any adjournment thereof.

A holder of Common Shares should use the enclosed blue form of proxy, and a holder of Non-Voting Shares should use the enclosed green form of proxy.

Revocation of Proxy

A Shareholder executing the enclosed form of proxy has the right to revoke it under subsection 148(4) of the CBCA. A Shareholder may revoke a proxy by depositing an instrument in writing executed by him or her, or by his or her attorney authorized in writing, at the registered office of Call-Net at any time up to and including the second business day preceding the day of the Meeting, or any adjournment thereof, at which the proxy is to be used, or with the Chairman of the Meeting on the day of the Meeting, or any adjournment thereof, or in any other manner permitted by law.

Exercise of Proxy

The Call-Net Shares represented by the proxy will be voted for or against in accordance with the instructions of the Shareholder on any vote that may be called for and, if the Shareholder specifies a choice with respect to any matter to be acted upon at the Meeting, Call-Net Shares represented by properly executed proxies will be voted accordingly.

In the absence of any instructions to the contrary, the Call-Net Shares represented by proxies received by management will be voted for the approval of the Arrangement Resolution as described in this Circular.

The enclosed form of proxy confers discretionary authority upon the persons named therein with respect to amendments or variations to the matter identified in the Notice of Meeting and with respect to other matters which may properly come before the Meeting or any adjournments thereof. At the date of this Circular, management of Call-Net knows of no such amendments, variations or other matters to come before the Meeting other than the matter referred to in the Notice of Meeting. If any other matters do properly come before the Meeting, it is intended that the person appointed as proxy shall vote on such other business in such manner as that person then considers to be proper.

Explanation of Voting Rights for Beneficial Owners of Shares

If Call-Net Shares are not registered in a Shareholder’s name but are held in the name of a nominee (a bank, trust company, securities broker, trustee or other similar entity), there are two ways the Shareholder can vote the Call-Net Shares held on his or her behalf by the nominee.

As required by Canadian securities legislation, such a Shareholder will have received from his or her nominee either a request for voting instructions or a form of proxy for the number of Call-Net Shares held by the nominee on his or her behalf. For such a Shareholder’s Call-Net Shares to be voted, he or she should follow the voting instructions provided by his or her nominee.

Since Call-Net has limited access to the names of its non-registered Shareholders, if such a Shareholder attends the Meeting, Call-Net may have no record of his or her shareholdings or of his or her entitlement to vote unless their nominee has appointed him or her as proxyholder. Therefore, if such a Shareholder wishes to vote in person at the Meeting, he or she should insert his or her own name in the space provided on the request for voting instructions or form of proxy to be appointed as proxyholder and return same in the envelope provided. They should not otherwise complete the form, as their vote will be taken at the Meeting. Such a Shareholder should register with the transfer agent, CIBC Mellon, upon arrival at the Meeting.

Shares and Principal Holders Thereof

Call-Net has an authorized share capital consisting of an unlimited number of Common Shares, Non-Voting Shares and Call-Net Preferred Shares.

As at May 18, 2005, 3,995,437 Common Shares, 31,894,503 Non-Voting Shares, and one Call-Net Preferred Share were issued and outstanding. Each Common Share entitles the holder thereof to one vote at all meetings of Shareholders. Non-Voting Shares do not generally carry voting rights, however for purposes of approving the Arrangement Resolution the holders of Non-Voting Shares will be entitled to one vote for each share held. The Call-Net Preferred Share, which is currently held by Sprint, does not generally carry voting rights. However, the holder of the Call-Net Preferred Share is entitled to elect two (2) members of the Board of Directors.

The presence, in person or by proxy, of two or more Shareholders is necessary for a quorum at the Meeting. The Board has fixed the close of business on May 17, 2005 as the record date for the purpose of determining the Shareholders entitled to receive notice of the Meeting, but the failure of any Shareholder to receive notice of the Meeting does not deprive the Shareholder of the right to vote at the Meeting.

For purposes of the Meeting, Call-Net has prepared a list of Shareholders who were registered on the records of Call-Net or its transfer agent, CIBC Mellon, at the close of business on May 17, 2005. Each Shareholder named on the list is entitled, upon providing satisfactory identification to the scrutineers, to vote the Call-Net Shares shown on such list as being held by such Shareholder (other than Call-Net Shares for which a proxy has been given and not revoked). Holders of Call-Net Shares issued after May 17, 2005 will be entitled to vote such Call-Net Shares at the Meeting, provided such holders are registered in the records of Call-Net or its transfer agent, CIBC Mellon, prior to the time of the Meeting.

Other than as set out below, to the knowledge of Call-Net and its directors and officers, no person or corporation beneficially owns, directly or indirectly, or exercises control or direction over, Common Shares, Non-Voting Shares or Call-Net Shares representing more than 10% of the issued and outstanding Common Shares, Non-Voting Shares or Call-Net Shares, respectively, as of May 24, 2005:

Restrictions on the Transfer, Voting and Issue of Shares

In order to ensure that Call-Net and any Canadian corporation in which Call-Net has a direct or indirect interest remains qualified to own or operate as a telecommunications common carrier pursuant to the Telecommunications Legislation, and to ensure that Call-Net and any Canadian corporation in which Call-Net has an interest is not otherwise in breach of the Telecommunications Legislation or licences issued to it or to any Canadian subsidiary, associate or affiliate of it under the Telecommunications Legislation, the Articles of Call-Net impose certain restrictions on the issue and transfer of the Common Shares and the exercise of voting rights attached thereto (the “Conditions of Restriction”) as applicable to the Constrained Class, as described below.

The Board has implemented Conditions of Restriction for any person who is not a Canadian or who is a member of the Constrained Class (the “Rules”).

Pursuant to the Rules, the Board must not issue and shall refuse to register a transfer of, or allow the exercise of voting rights attached to Common Shares, in circumstances that would result in persons of the Constrained

Class holding more than 33¹/3% of the outstanding number of Common Shares (or such different percentage as may be prescribed from time to time under the Telecommunications Legislation).

“Constrained Class” means persons who are not Canadians within the meaning of that term in the Regulations made under the Telecommunications Act (Canada).

ADDITIONAL INFORMATION

Call-Net will provide to any person or company, upon receipt of a request by the Secretary of Call-Net, a copy of:


	(i)	the most recent Annual Information Form (“AIF”), together with one copy of any document, or the pertinent pages of any document, incorporated by reference in the AIF;

	(ii)	the most recently filed audited annual consolidated financial statements, together with the accompanying report of the auditor, and any unaudited interim consolidated financial statements that have been filed for any period after the end of its most recently completed financial year; and

BETWEEN:


	ROGERS COMMUNICATIONS INC., a corporation subsisting under the laws of British Columbia

	(hereinafter referred to as the “Purchaser”)

	- and -

	CALL-NET ENTERPRISES INC., a corporation incorporated under the laws of Canada

	(hereinafter referred to as “Call-Net”)

THIS AGREEMENT WITNESSES THAT, in consideration of the premises and the respective covenants and agreements herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by each of the parties hereto, the parties hereto hereby covenant and agree as follows:

ARTICLE 1

DEFINITIONS AND PRINCIPLES OF INTERPRETATION

1.1 Definitions

In this Agreement, unless there is something in the subject matter or context inconsistent therewith, the following capitalized words and terms shall have the following meanings:


	“Acquisition Proposal” means any (i) merger, amalgamation, statutory arrangement, recapitalization or take-over bid, (ii) sale of assets (or any lease, long-term supply agreement or other arrangement having the same economic effect as a sale of assets) having a fair market value in excess of Cdn.$10 million, (iii) any liquidation and/or (iv) any sale of a material number of shares or rights or interests therein or thereto or similar transactions involving any of the Call-Net Entities, or a proposal to do so, excluding the Arrangement and excluding any such sale pursuant to presently outstanding Call-Net PUs or Call-Net Options in accordance with the terms thereof;

	(b)	the Purchaser and Call-Net shall provide each other with copies of all registrations, filings and submissions referred to in (a) above;

	(c)	all requests and enquiries from any Governmental Entity shall be dealt with by the Purchaser and Call-Net in consultation with each other, and the Purchaser and Call-Net shall promptly co-operate with and provide all necessary information and assistance reasonably required by such Governmental Entity upon being requested to do so by such authority or by the other party;

	(d)	the Purchaser and Call-Net shall promptly notify the other of material written communications of any nature from any Governmental Entity and provide the other party with copies thereof;

	(e)	the Purchaser and Call-Net shall permit the other to review in advance for consultation purposes any proposed material written communications of any nature with Governmental Entities;

	(f)	neither the Purchaser nor Call-Net shall participate in any substantive meeting or discussion (whether in person, by telephone or otherwise) with any Governmental Entity in respect of any filings, investigation or inquiry concerning the Arrangement unless it consults with the other party in advance and gives the other party the opportunity to attend and participate thereat (except to the extent that in any such case the Governmental Entity expressly requests that the other party should not be present at the meeting or discussion or part or parts of the meeting or discussion); and

	(g)	Call-Net shall not extend or consent to any extension of any waiting period under applicable Laws or enter into any agreement with any Governmental Entity to not consummate the Arrangement, except with the consent of the Purchaser;

provided, however, where either the Purchaser or Call-Net, as the case may be, is obligated to provide information that it deems to be competitively sensitive information to the other party, the Purchaser or Call-Net, as the case may be, shall provide such competitively sensitive information only to the external legal counsel of the other party or to external experts hired by external counsel to the Purchaser or Call-Net and such competitively sensitive information shall not be shared by such counsel or external experts with any other Person.

4.2 Obtaining of Appropriate Regulatory Approvals

For purposes of this Agreement, no Appropriate Regulatory Approval shall be considered to have been obtained if it contains any condition that would result in the Call-Net Entities or the Rogers Entities, following implementation of the Arrangement, being in a materially worse position than such Call-Net Entities or Rogers Entities as of the date hereof. In addition, at the option of the Purchaser, no Appropriate Regulatory Approval shall be considered to have been obtained if an appeal by a Person other than a Call-Net Entity or Rogers Entity has been instituted from the granting of any Appropriate Regulatory Approval and remains outstanding.

ARTICLE 5

COVENANTS

5.1 Material Commitments

Subject to compliance with applicable Laws, during the Pre-Effective Date Period, Call-Net will use reasonable efforts to consult on an ongoing basis with the Purchaser in order that the representatives of the Purchaser will become more familiar with the philosophy and techniques of the Call-Net Entities as well as with their business and financial affairs and in order to provide experience as a basis for ongoing relationships in connection with the acquisition of Call-Net by the Purchaser as of the Effective Date. These consultations will include reasonable efforts to consult with respect to any commitments, arrangements or transactions proposed to be entered into that would be out of the ordinary course of business and that could reasonably be expected to give rise to a material liability or commitment of any kind and will use reasonable efforts to allow sufficient time for the Purchaser to give reasonable consideration to the same. Call-Net and the Purchaser will develop procedures such that these consultations will be carried out quickly and effectively without detracting from the ability of Call-Net to arrive at decisions in a timely manner. In addition, Call-Net shall provide to the Purchaser copies of any interim financial statements (and any management reviewed drafts thereof) which may be prepared from time to time during the Pre-Effective Date Period.

5.2 Covenants of Call-Net

	(xiii)	not enter into, other than as contemplated in the Call-Net Disclosure Materials, any non-arm’s length transactions or permit any of the Call-Net Entities to grant to any of their respective directors or officers any increase in compensation (other than routine annual increases in the ordinary course of business consistent with past practice) or, other than Termination Entitlements disclosed in the Call-Net Disclosure Materials, to pay any severance or termination amounts whether or not such compensation, payment or amount is payable in cash, or enter into or modify any employment arrangements or Contract with any such Person (whether with an existing employee or a new employee) or any agreement to pay severance amounts for termination or termination packages (or enter into any commitment for such payment);

B-34


	(xv)	take all action necessary pursuant to the Call-Net Shareholder Rights Plan to effect the waiver referred to in Section 3.1(qq), such waiver to become effective on or before the Effective Time;

	(xvi)	promptly advise the Purchaser in writing forthwith upon acquiring knowledge of:


	(A)	any event occurring subsequent to the date of this Agreement that would render any representation or warranty of Call-Net 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)	any event that would reasonably be expected to have a Material Adverse Effect in respect of Call-Net;

	(C)	any breach by Call-Net of any covenant or agreement contained in this Agreement; and

	(D)	any death, disability, resignation, termination of employment or other departure of any senior officer or senior employee of any of the Call-Net Entities.


	(b)	Subject to sections 5.4 and 5.5, Call-Net shall, and shall cause each of the other Call-Net Entities to, perform all obligations required to be performed by them under this Agreement and shall do all such other acts and things as may be reasonably necessary in order to consummate and make effective, as soon as reasonably practicable, the transactions contemplated in this Agreement and, without limiting the generality of the foregoing (provided that in no event shall Call-Net thereby be obliged to breach section 9.3), Call-Net shall and, where appropriate, shall cause the other Call-Net Entities to:


	(i)	recommend in the Proxy Circular and at the Call-Net Meeting that the Call-Net Shareholders vote in favour of the Arrangement, and Call-Net shall not act or fail to act in any way that would reasonably be expected to discourage Call-Net Shareholders from voting in favour of the Arrangement Resolution or that might encourage Call-Net Shareholders to vote against the Arrangement Resolution,

	(ii)	not withdraw its recommendation that Call-Net Shareholders vote in favour of the Arrangement and not delay, adjourn, postpone or cancel the Call-Net Meeting;

	(iii)	instruct the Call-Net registrar and transfer agent or depositary to furnish to the Purchaser daily status reports as to the tabulation of forms of proxy in connection with the Call-Net Meeting;

	(v)	together with the Purchaser to the extent it deems appropriate, apply for and use commercially reasonable efforts to obtain the Interim Order and the Final Order;

	(vi)	use commercially reasonable efforts to defend all lawsuits or other legal, regulatory or other proceedings challenging or affecting Call-Net’s property or assets, this Agreement or the consummation of the transactions contemplated hereby;

	(vii)	to the extent necessary to permit implementation of the Arrangement and as otherwise reasonably required by the Purchaser, use commercially reasonable efforts to have lifted or rescinded any injunction or restraining order or other order relating to the Call-Net Entities,

B-35


		including any cease trade orders of securities regulatory authorities, which may adversely affect the ability of the parties to consummate the transactions contemplated hereby; and

	(viii)	if for any reason whatsoever, except by reason of a material breach by the Purchaser of its obligations hereunder, the Arrangement cannot be completed on the basis contemplated by this Agreement, negotiate in good faith with the Purchaser to restructure the transactions contemplated by this Agreement and the Plan of Arrangement on a mutually acceptable basis and with completion of the Arrangement to occur on or before September 30, 2005 and, for greater certainty, if the transactions contemplated by this Agreement and the Plan of Arrangement are so restructured, section 8.2 shall apply to the restructured transactions.


	(c)	During the period subsequent to the Call-Net Shareholders approving the Arrangement and prior to any required approval of the Court in relation to the Arrangement being obtained, with effect immediately prior to the Effective Time, Call-Net shall, and shall cause each of the remaining Call-Net Entities to, take such actions as are necessary or desirable to reorganize the capital and assets of the Call-Net Entities as the Purchaser may reasonably require; provided, however, that no such reorganization will be undertaken if (i) it would reduce the fixed per share consideration payable by the Purchaser to the Call-Net Shareholders pursuant to the Arrangement, (ii) the Purchaser has not agreed to pay the actual out-of-pocket costs and expenses (including for filing fees and external counsel and auditors) which may be incurred relating to such restructuring in the event that the Final Order is not obtained or (iii) Call-Net has not been provided with appropriate undertakings to discharge and cancel any security documents executed and delivered by Call-Net Entities in the event that the Final Order is not obtained. In addition and without limiting the generality of the foregoing, subsequent to the Call-Net Shareholders approving the Arrangement and prior to any required approval of the Court in relation to the Arrangement being obtained, with effect immediately prior to the Effective Time, subject to clauses (i), (ii) and (iii) above, Call-Net shall, and shall cause each of the remaining Call-Net Entities to, take such actions as are commercially reasonable and as the Purchaser may reasonably require to facilitate planning for the orderly sale or the orderly integration of the Call-Net Entities and their respective businesses and assets into the Purchaser’s operations.

	(d)	The Parties agree that if Call-Net or the Purchaser proposes any amendment to this Agreement or to the Plan of Arrangement, the other will act reasonably in considering such amendment and if the other and, in the case of Call-Net, its security holders, are not prejudiced in any material respect by reason of any such amendment the other will cooperate in a reasonable fashion with Call-Net or the Purchaser, as the case may be, so that such amendment can be effected, subject to applicable Laws and the rights of the Call-Net Shareholders.

5.3 Covenants of Purchaser

The Purchaser hereby covenants and agrees to perform all obligations required or desirable to be performed by it under this Agreement and to do all such other acts and things as may be necessary or desirable in order to consummate and make effective, as soon as reasonably practicable, the transactions contemplated by this Agreement and, without limiting the generality of the foregoing, to:


	(a)	use all commercially reasonable efforts to defend all lawsuits or other legal, regulatory or other proceedings to which it is a party challenging or affecting this Agreement or the consummation of the transactions contemplated hereby;

	(b)	use all commercially reasonable efforts to have lifted or rescinded any injunction or restraining order or other order relating to the Purchaser which may adversely affect the ability of the parties to consummate the transactions contemplated hereby;

	(e)	if for any reason whatsoever, except by reason of a material breach by Call-Net of its obligations hereunder, the Arrangement cannot be completed on the basis contemplated by this Agreement, negotiate in good faith with Call-Net to restructure the transactions contemplated by this Agreement and the Plan of Arrangement on a mutually acceptable basis and with completion of the Arrangement to occur on or before September 30, 2005 and, for greater certainty, if the transactions contemplated by this Agreement and the Plan of Arrangement are so restructured, section 7.3(d) shall apply to the restructured transactions;

	(f)	subject to compliance with applicable Laws, continue to provide Call-Net and its Representatives with information as reasonably requested by them from time to time concerning the business, assets, liabilities and affairs of the Purchaser, and with access (on a basis that does not detract unreasonably from the performance of their business responsibilities) to management and employees of the Purchaser;

	(g)	on or after the Effective Time, take all action necessary to cause Call-Net to comply with the terms and provisions of the Termination Entitlements to the extent the same have been disclosed to the Purchaser in writing prior to the date hereof; for greater certainty and without limiting the generality of the foregoing, certain members of Call-Net’s senior management will be paid their full entitlement to such compensation on the implementation of the Arrangement, all as described in the Call-Net Disclosure Letter;

	(h)	to the extent necessary to permit implementation of the Arrangement and as otherwise reasonably required by the Purchaser, use all commercially reasonable efforts to have lifted or rescinded any injunction or restraining order or other order relating to the Rogers Entities, including any cease trade orders of securities regulatory authorities, which may adversely affect the ability of the parties to consummate the transactions contemplated hereby;

	(i)	not split, combine or reclassify the RCI Class B Shares unless an appropriate adjustment is made to the number of RCI Class B Shares to be issued pursuant to the Arrangement;

	(C)	of any breach by the Purchaser of any covenant or agreement contained in this Agreement;


	(k)	not take any action that would interfere with or be inconsistent with the completion of the transaction contemplated by the Agreement;

B-37

5.4 Covenants Regarding Non-Solicitation


	(a)	Subject to section 5.5 and applicable Laws, Call-Net shall:


	(A)	not, directly or indirectly, through any officer, director, employee, representative or agent of Call-Net or any of the other Call-Net Entities, 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 Purchaser the approval of Call-Net’s board of directors of the transactions contemplated hereby, accept or approve or recommend any Acquisition Proposal or enter into any agreement related to any Acquisition Proposal;

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

	(C)	not 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

	(D)	immediately cease to provide any other party with access to information concerning the Call-Net Entities (or any of them) and request the return or destruction of all confidential information provided to any third party that has entered into a confidentiality agreement with Call-Net relating to any potential Acquisition Proposal;

provided, however, that, subject to section 5.5 but notwithstanding the preceding part of this section and any other provision of this Agreement, nothing shall prevent the Call-Net board of directors from (x) complying with Call-Net’s disclosure obligations under applicable Law with respect to an unsolicited bona fide written Acquisition Proposal; (y) considering, negotiating or discussing (and providing non-public information in response to) a Superior Proposal or (z) withdrawing or modifying its recommendation that Call-Net shareholders vote in favour of the Arrangement, if the Call-Net board of directors has so determined that an Acquisition Proposal is a Superior Proposal.


	(b)	Call-Net represents and warrants that, other than under this Agreement, there is no current Acquisition Proposal that is a Superior Proposal. Call-Net shall immediately notify the Purchaser, at first orally and then (if the Purchaser so requests) in writing, of all Acquisition Proposals, of which Call-Net’s directors or officers become aware, or any amendments to the foregoing, or any request for non-public information relating to any of the Call-Net Entities in connection with an Acquisition Proposal or for access to the properties, books or records of any of the Call-Net Entities by any Person that informs Call-Net that such Person is considering making an Acquisition Proposal. Such notice shall include, to the extent known, a full description of the material terms and conditions of any proposal and provide such details of the proposal, inquiry or contact as the Purchaser may reasonably request including the identity of the Person making such proposal, inquiry or contact. Such notice shall include or be subsequently accompanied by as soon as reasonably practicable after delivery of such notice, inter alia, the written statement of Call-Net’s board of directors regarding the value in financial terms which such board of directors has, in consultation with its financial advisers, determined should be ascribed to any non-cash consideration included in the Acquisition Proposal.

	(c)	If Call-Net receives a request for material non-public information from a Person who has made an unsolicited bona fide written Acquisition Proposal and Call-Net is permitted, subject to and as contemplated under subsection (a) of this section, to negotiate the terms of such Acquisition Proposal, then, and only in such case, the Call-Net board of directors may, subject to the execution by such Person of a confidentiality agreement (which, subject to the balance of this clause (c), shall in no respect be more favourable to such Person than the terms of the Purchaser Confidentiality Obligation to the Purchaser), provide such Person with access to information regarding Call-Net and its Subsidiaries; provided, however, that the Person making the Acquisition Proposal shall not be precluded under such confidentiality agreement from making an Acquisition Proposal which is a Superior Proposal and provided further that Call-Net sends a copy of any such confidentiality

B-38


		agreement to the Purchaser promptly upon its execution and the Purchaser is provided with a list of or copies of the information provided to such Person and immediately provided with access to similar information to which such Person was provided.

	(d)	Call-Net shall advise all officers, directors, employees and agents of the Call-Net Entities and any financial advisors or other advisors or representatives retained by any of them of the provisions of this section, and it shall be responsible for any breach of this section by its financial advisors or other advisors or representatives agents.

5.5 Notice by Call-Net of Superior Proposal Determination

Call-Net shall not accept, approve, recommend or enter into any agreement relating to an Acquisition Proposal (other than a confidentiality agreement) on the basis that it would constitute a Superior Proposal unless:


	(a)	the Call-Net board of directors shall have determined in good faith that the Acquisition Proposal constitutes a Superior Proposal,

	(b)	Call-Net has provided the Purchaser with a copy of the Acquisition Proposal document which the Call-Net board of directors has determined would be a Superior Proposal,

	(c)	five Business Days shall have elapsed from the later of the date the Purchaser receives notice of Call-Net’s proposed determination to accept, approve, recommend or enter into any agreement relating to such Acquisition Proposal, and the date the Purchaser received a copy of the Acquisition Proposal and

	(d)	Call-Net is not in any material respect (x) in default under this Agreement or (y) in breach of any of its representations or warranties contained herein.

For greater certainty, Call-Net shall not, without the Purchaser’s approval (not to be unreasonably withheld and delayed), adjourn, delay or cancel the Call-Net Meeting; provided that either Call-Net or the Purchaser may require that the Call-Net Meeting be adjourned or delayed for up to ten Business Days in the event that an Acquisition Proposal which could be a Superior Proposal is publicly announced or submitted to Call-Net.

During the five Business Day period referred to in (c) above, Call-Net acknowledges that the Purchaser shall have the opportunity, but not the obligation, to offer to amend the terms of this Agreement and the Arrangement. The Call-Net board of directors will review any offer by the Purchaser to amend the terms of this Agreement in good faith in order to determine, in its discretion in the exercise of its fiduciary duties, whether the Purchaser’s offer to amend the terms of this Agreement upon acceptance by Call-Net would result in the Acquisition Proposal not being a Superior Proposal. If the Call-Net board of directors so determines, Call-Net will enter into an amended agreement with the Purchaser reflecting the Purchaser’s amended proposal. If the Call-Net board of directors continues to believe, in good faith and after consultation with financial advisors and outside counsel, that the Acquisition Proposal is nonetheless a Superior Proposal and therefore rejects the Purchaser’s amended proposal, Call-Net will pay to the Purchaser the break fee payable to the Purchaser under section 8.2 as required thereunder, and Call-Net may approve, recommend, accept or enter into an agreement, understanding or arrangement with respect to the Superior Proposal and Call-Net may proceed with such approvals, consents, filings, of or required by Governmental Entities and such other Persons as Call-Net shall consider appropriate in order to consummate such Superior Proposal.

Call-Net shall promptly reaffirm its recommendation of the Arrangement by press release: (x) after any Acquisition Proposal (which is determined not to be a Superior Proposal) is publicly announced or made, or (y) after the Purchaser increases (by written notice to Call-Net), within five Business Days after receiving written notice from Call-Net pursuant to this section, the consideration offered under the Arrangement to match or better the consideration under a Superior Proposal.

Call-Net also acknowledges and agrees that each successive modification of any Acquisition Proposal shall constitute a new Acquisition Proposal for purposes of this section.

B-39

5.6 Access to Information

Subject to the remaining subsections of this paragraph and applicable Laws, upon reasonable notice, Call-Net shall (and shall cause each of the other Call-Net Entities to) afford the Purchaser’s officers, employees, counsel, accountants, financiers (and their counsel) and other authorized representatives and advisors (“Representatives”) reasonable access, during normal business hours from the date hereof and until the earlier of the Effective Date or the termination of this Agreement, to its properties, books, Contracts and records as well as to its management personnel, and, during such period, Call-Net shall (and shall cause each of the other Call-Net Entities to) furnish promptly to the Purchaser all information concerning the business, properties and personnel of the Call-Net Entities as the Purchaser may reasonably request to conduct such inspections, audits, interviews, investigations and other enquiries as the Representatives may determine reasonably necessary in connection with the transactions contemplated by this Agreement. The Purchaser acknowledges that certain information provided to it under this paragraph will be non-public and/or proprietary in nature and will be subject to the terms of the Purchaser Confidentiality Obligation. Any access provided pursuant to this paragraph shall be effected in such a manner as will, to the extent reasonable in the circumstances, minimize disruption to the Call-Net Entities.

Subject to the remaining subsections of this paragraph and applicable Laws, upon reasonable notice, the Purchaser shall permit Call-Net to engage in reasonable due diligence regarding the Purchaser’s representations and warranties contained herein. Call-Net acknowledges that certain information provided to it under this paragraph will be non-public and/or proprietary in nature and will be subject to the terms of the Call-Net Confidentiality Obligation.

5.7 Closing Matters

Each of the Purchaser and Call-Net shall deliver or cause to be delivered at the closing of the transactions contemplated hereby such customary certificates, resolutions and other closing documents as may be required by the other party hereto, acting reasonably.

5.8 Indemnification


	(a)	The Purchaser agrees that all rights to indemnification or exculpation now existing in favour of present or former directors or officers of Call-Net Entities as provided in their Charter Documents or indemnification agreements, copies of which have been made available to the Purchaser prior to the date of the execution of this Agreement, in effect on the date hereof shall survive the Arrangement and shall continue in full force and effect for a period of not less than six years from the Effective Date.

	(b)	The Purchaser 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 Call-Net Entities on a six year “trailing” (or “run-off”) basis. If a trailing policy is not available at a reasonable cost, then the Purchaser agrees that, for the entire six year period from the Effective Date, the Purchaser shall cause Call-Net to maintain (subject to the same being available on commercially reasonable terms) its 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 Call-Net Entities than those contained in the policy in effect on the date hereof, for all current and former directors of the Call-Net Entities, covering claims made prior to or within six years of the Effective Date. Further, the Purchaser agrees that, after the expiration of the six year period, if there is no material cost in doing so, the Purchaser shall use reasonable commercial efforts to cause such directors and officers to be covered under the Purchaser’s then existing directors’ and officers’ liability insurance policy.

	(c)	From and after the Effective Date, the Purchaser shall not do anything to prevent the Call-Net Entities from indemnifying and holding harmless and providing advancement of expenses to, all past and present directors and officers of the Call-Net Entities to the extent such persons are lawfully entitled to indemnity from the Call-Net Entities or have the right to advancement of expenses as of the date of this Agreement by the Call-Net Entities pursuant to the Call-Net Entities’ by-laws and indemnity agreements in existence immediately prior to the Effective Date (including acts or omissions occurring

B-40


		in connection with the approval of this Agreement and consummation of the transactions contemplated hereby). The Purchaser will not (unless it assumes such obligations and gives written notice to the beneficiaries thereof to the extent it has their addresses) liquidate Call-Net if the same would prejudice the satisfaction of the indemnity obligations referred to herein or otherwise take any other action to materially adversely affect satisfaction of the indemnity obligations referred to herein.

	(d)	The provisions of this section are intended to be for the benefit of, and shall be enforceable by, each present or former director or officer of the Call-Net Entities and their respective estates, heirs, legal representatives and assigns (collectively, the “Beneficiaries”) and the Purchaser acknowledges that Call-Net accepts the Purchaser’s covenants under this section as trustee for and on behalf of each of such Beneficiaries.

5.9 Actions to Satisfy Conditions

Each party agrees to take all such actions as are within its power to control, and to use all commercially reasonable efforts to cause other actions to be taken which are not within its power to control, so as to be able to comply with any conditions set forth in Article 6 which are for the benefit of any other party, provided that in fulfilment of the foregoing covenant, the Purchaser shall not be required to make any payments (except for filing and other prescribed fees) or divest or otherwise deal with any assets owned or controlled by it, nor shall the Purchaser be required to accept any condition that would result in the Call-Net Entities or the Rogers Entities, following the implementation of the Arrangement, being in a materially worse position that such Call-Net Entities or Rogers Entities as of the date hereof.

5.10 Special Provisions Regarding Call-Net Options and Call-Net PUs

B-44


6.4	Notice and Cure Provisions

The Purchaser and Call-Net will give prompt notice to the other of the occurrence, or failure to occur, at any time from the date hereof until the Effective Date, of any event or state of facts which occurrence or failure would, or would reasonably be expected to:


	(a)	cause any of the representations or warranties of the other contained herein to be untrue or inaccurate in any material respect on the date hereof or on the Effective Date; or

	(b)	result in the failure to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by the other hereunder at or prior to the Effective Time.

Neither the Purchaser nor Call-Net may elect not to complete the transactions contemplated hereby pursuant to the conditions precedent contained in sections 6.1, 6.2 and 6.3, or exercise any termination right arising therefrom, unless forthwith and in any event prior to the filing of the Articles of Arrangement for acceptance by the Director, the Purchaser or Call-Net, as the case may be, has delivered a written notice to the other specifying in reasonable detail all breaches of covenants, representations and warranties or other matters which the Purchaser or Call-Net, as the case may be, is asserting as the basis for the non-fulfilment of the applicable condition precedent or the exercise of the termination right, as the case may be. If any such notice is delivered, provided that the Purchaser or Call-Net, as the case may be, is proceeding diligently to cure such matter, if such matter is capable of being cured, the other may not terminate this Agreement until the expiration of a period of 30 days from such notice (and then only if such breach remains uncured), unless the breach or matter relates to non-compliance by Call-Net of its obligations under section 5.4 or 5.5 (in respect of which no cure period shall be available to Call-Net) or section 5.6 (in respect of which the cure period shall be five Business Days). If such notice has been delivered prior to the date of the Call-Net Meeting, such meeting shall be postponed until the expiry of such period. If such notice has been delivered prior to the making of the application for the Final Order or the filing of the Articles of Arrangement with the Director, such application and such filing shall be postponed until the expiry of such period. For greater certainty, in the event that such matter is cured within the time period referred to herein (in the case of Call-Net, provided further that such matter is so cured without a Material Adverse Effect), this Agreement may not be terminated as a result of the cured breach.


6.5	Satisfaction of Conditions

	(f)	the holders of Call-Net PUs.


2.2	Arrangement

At the Effective Time, the following shall occur and shall be deemed to occur in the following order without any further act or formality:


	(a)	the Call-Net Rights Plan shall be deemed to have been terminated (and all rights issued thereunder shall expire) immediately prior to the Effective Time and shall be of no further force or effect and each Call-Net Share (other than Call-Net Shares in respect of which the Call-Net Shareholder has validly exercised his right of dissent) shall be directly transferred and assigned by the Non-Taxable Holders to Call-Net Acquisition Company and by the other Call-Net Shareholders to RCI in consideration for RCI Class B Shares on the basis of a ratio of one RCI Class B Share for every 4.25 Call-Net Shares;

	(b)	each Call-Net Share in respect of which the Call-Net Shareholder has validly exercised his right of dissent shall be directly transferred and assigned by such Call-Net Shareholders to Call-Net in accordance with Article 3;

	(c)	unless RCI otherwise notifies the Secretary of Call-Net in writing prior to the Effective Date, each Call-Net Preferred Share shall be deemed to be redeemed by Call-Net for $1.00, being the redemption price therefor;

	(d)	with respect to each Call-Net Share transferred and assigned in accordance with Subsection 2.2(a) or Subsection 2.2(b):


	(i)	the registered holder thereof shall cease to be the registered holder of such Call-Net Share and the name of such registered holder shall be removed from the register of Call-Net Shareholders as of the Effective Time;

	(ii)	the certificate representing such Call-Net Share shall be deemed to have been cancelled as of the Effective Time; and

	(iii)	the registered holder thereof shall be deemed to have executed and delivered all consents, releases, assignments and waivers, statutory or otherwise, required to transfer and assign such Call-Net Share in accordance with Subsection 2.2(a) or Subsection 2.2(b), as applicable;


	(e)	with respect to each Call-Net Preferred Share redeemed in accordance with Subsection 2.2(a):

	(iii)	the registered holder thereof shall be deemed to have executed and delivered all consents, releases, assignments and waivers, statutory or otherwise, required to effect the redemption thereof;


	(f)	with respect to any Call-Net Options outstanding and unexercised immediately prior to the Effective Date (whether or not then vested), each holder thereof shall receive, as of the Effective Date, options to acquire RCI Class B Shares under RCI’s stock option plan (“RCI Options”) in replacement for and in lieu of such Call-Net Options on the basis that (A) such RCI Options will be exercisable to acquire a like number of RCI Class B Shares as each holder of Call-Net Options would have acquired if all such Call-Net Options held by each such holder were fully vested and if each such holder had

B-55


		exercised such Call-Net Options immediately prior to the Effective Date and had received Call-Net Shares that had been subject to Subsection 2.2(a), (B) the vesting for such RCI Options will be identical to the vesting applicable to such Call-Net Options, (C) the expiry date for such RCI Options shall be identical to the original expiry date for such Call-Net Options and (D) the aggregate exercise price for such RCI Options shall be equal to the aggregate exercise price of the Call-Net Options replaced by such RCI Options, such calculation to be applied separately to each grant of Call-Net Options (attached as Exhibit A is an example of the calculation of the exercise price per RCI Class B Share); provided that, if the foregoing calculation results in a holder receiving options exercisable for a fraction of an RCI Non-Voting Share, the number of RCI Options received on the exchange shall be rounded down to the next whole RCI Option and the total exercise price for the RCI Options will be reduced by the exercise price of the fractional RCI Non-Voting Share. Notwithstanding the foregoing, the holder of a Call-Net Option may, at his or her sole option and at any time, before the Effective Time, notify RCI in writing that he or she wishes to increase the exercise price per RCI Non-Voting Share for his or her RCI Options, in the event that the value of such RCI Options immediately after the Effective Time exceeds the value of the Call-Net Options immediately before the Effective Time, to the amount necessary to make the value of such RCI Options immediately after the Effective Time equal to the value of such Call-Net Options immediately before the Effective Time and, in the event such notice is given, the exercise price under the RCI Options shall be deemed to be equal to such amount;

	(g)	with respect to any Call-Net PUs outstanding and unexercised immediately prior to the Effective Date (whether or not then vested), in no event shall they represent any entitlement to receive or otherwise acquire Call-Net Shares or to acquire RCI Class B Shares, but otherwise the rights of a holder thereof shall be unaffected and each such holder shall be paid on the Effective Date the amount to which such holder is entitled in respect of such holder’s Call-Net PUs.

provided that none of the foregoing shall occur or shall be deemed to occur unless all of the foregoing occur.

ARTICLE 3

RIGHTS OF DISSENT

	(a)	are ultimately entitled to be paid fair value in cash for their Call-Net Shares shall be deemed to have transferred such Call-Net Shares to Call-Net for cancellation at the Effective Time; or

	(b)	are ultimately not entitled, for any reason, to be paid fair value in cash for their Call-Net Shares shall be deemed to have participated in the Arrangement on the same basis as any non-dissenting Call-Net Shareholder as, at and from the Effective Time, and, subject to Article 4, shall receive RCI Class B Shares on the basis determined in accordance with Article 2;

but, for greater certainty, in no case shall Call-Net, Call-Net Acquisition Company or RCI be required to recognize such Call-Net Shareholders as Call-Net Shareholders at and after the Effective Time, and the names of such Call-Net Shareholders shall be deleted from the register of Call-Net Shareholders as of the Effective Time.

B-56

ARTICLE 4

PAYMENT OF CONSIDERATION

4.1 Payment to Registered Holders


	(a)	As soon as reasonably practicable but in any event within five Business Days after the later of the Effective Date and the delivery to the Depositary of a duly completed Letter of Transmittal and the certificates representing Call-Net Shares, RCI shall cause the Depositary:


	(i)	to forward or cause to be forwarded by first class mail to the Call-Net Shareholder at the address specified in the Letter of Transmittal;

	(ii)	if requested by the Call-Net Shareholder in the Letter of Transmittal, to make available at the offices of the Depositary for pick up by the Call-Net Shareholder; or

	(iii)	if the Letter of Transmittal neither specifies an address nor contains a request as described in (B) above, to forward or cause to be forwarded by first class mail to the Call-Net Shareholder at the address of the Call-Net Shareholder as shown on the share register maintained by Call-Net immediately prior to the Effective Time;


	(b)	As soon as reasonably practicable but in any event at least one Business Day prior to RCI being required to make a cash payment contemplated by this Section 4.1 or Section 4.2, RCI will provide the Depositary with sufficient funds to enable the Depositary to make such payments, with such funds to be provided by bank transfer or other means satisfactory to the Depositary, and such funds shall be held in trust for the Call-Net Shareholders and otherwise as contemplated in this Plan of Arrangement. All amounts paid to the Call-Net Shareholders pursuant to the Arrangement shall be without interest and any interest earned on funds held in trust for the Call-Net Shareholders pursuant to this Subsection 4.1(b) shall be for the sole benefit of RCI.

4.2 Lost Certificates

If any certificate which immediately prior to the Effective Time represented Call-Net Shares that were acquired by RCI pursuant to Subsection 2.2(a) has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Call-Net Shareholder claiming such certificate to be lost, stolen or destroyed and the delivery of a duly completed Letter of Transmittal, in exchange for such lost, stolen or destroyed certificate, within ten Business Days after the later of:


	(i)	the Effective Date; and

	(ii)	the delivery to the Depositary of a duly completed Letter of Transmittal, an affidavit of loss and the bond or other indemnity referred to below,

RCI will cause the Depositary:


	(A)	to forward or cause to be forwarded by first class mail to the Call-Net Shareholder at the address specified in the Letter of Transmittal;

	(B)	if requested by the Call-Net Shareholder in the Letter of Transmittal, to make available at the offices of the Depositary for pick up by the Call-Net Shareholder; or

B-57


	(C)	if the Letter of Transmittal neither specifies an address nor contains a request as described in (B) above, to forward or cause to be forwarded by first class mail to the Call-Net Shareholder at the address of the Call-Net Shareholder as shown on the share register maintained by Call-Net immediately prior to the Effective Time;

a share certificate representing the number of RCI Class B Shares to be delivered to such Call-Net Shareholder in respect of the Call-Net Shares for which a duly completed Letter of Transmittal and the bond or other indemnity referred to below have been delivered to the Depositary pursuant to the provisions hereof, provided that in no event shall any holder of Call-Net Shares be entitled to a fractional RCI Class B Share, but, rather, in lieu of any fractional entitlement that a Call-Net Shareholder would otherwise be entitled to, there shall be forwarded to such Call-Net Shareholder a cheque representing the amount of $3.70 for each whole one tenth of an RCI Class B Share that a Call-Net Shareholder would otherwise have been entitled to. A condition precedent to the delivery of any such share certificate or cheque shall be that the person entitled to same shall give a bond reasonably satisfactory to RCI and the Depositary in such reasonable sum as RCI may direct or otherwise indemnify RCI and the Depositary in a manner reasonably satisfactory to them against any claim that may be made against either of them with respect to the certificate alleged to have been lost, stolen or destroyed.

4.3 Extinction of Rights

If any Call-Net Shareholder fails for any reason to deliver to the Depositary for cancellation the certificates formerly representing Call-Net Shares (or an affidavit of loss and bond or other indemnity pursuant to Section 4.1), together with a duly completed Letter of Transmittal, on or before the sixth anniversary of the Effective Date, such Call-Net Shareholder shall be deemed to have donated and forfeited to RCI any cash, net of any applicable withholding or other taxes, held by the Depositary in trust for such Call-Net Shareholder to which such Call-Net Shareholder is entitled. Subject to this Section 4.3, at and after the Effective Time, any certificate formerly representing Call-Net Shares shall represent only the right to receive the consideration provided in Subsection 2.2(a) in accordance with this Plan of Arrangement, provided that such certificates shall, on the sixth anniversary of the Effective Date, cease to represent a claim of any nature whatsoever, shall be deemed to have been surrendered to RCI and shall be cancelled.

ARTICLE 5

AMENDMENT

5.1 Amendment


	(a)	RCI and Call-Net may amend, modify and/or supplement this Plan of Arrangement at any time and from time to time prior to the Effective Time, provided that any such amendment, modification or supplement must be approved by each of RCI and Call-Net in a written document which is filed with the Court and, if made following the Meeting, approved by the Court and communicated to Call-Net Shareholders in the manner required by the Court (if so required).

	(b)	Any amendment, modification or supplement to this Plan of Arrangement which is directed by the Court following the Meeting shall be effective only if (i) it is consented to in writing by RCI and Call-Net, and (ii) if required by the Court, it is consented to by the Call-Net Shareholders in the manner directed by the Court.

B-58

ARTICLE 6

FURTHER ASSURANCES

6.1 Other Documents and Instruments

Notwithstanding that the transactions or events set out herein shall occur and shall be deemed to occur in the order set out in this Plan of Arrangement without any further authorization, act or formality, RCI and Call-Net shall make, do and execute, or cause and cause to be made, done and executed, all such further acts, deeds, agreements, transfers, assurances, instruments or documents as may reasonably be required by either of them in order further to document or evidence any of the transactions or events set out herein including any resolutions of directors authorizing the issue, exchange, transfer, purchase for cancellation or donation of shares and any share transfer powers evidencing the transfer of shares and any receipts therefor.

B-59

EXHIBIT A

Assumptions:


	1.	A Person (the “Optionholder”) holds Call-Net Options which, if fully exercised, would entitle the Optionholder to acquire 4,250 Call-Net Shares.

	2.	The exercise price of such Call-Net Options is Cdn.$5 per Call-Net Share or Cdn.$21,250 in the aggregate.

	3.	On the Arrangement being implemented, a Call-Net Shareholder with 4,250 Call-Net Shares will receive 1,000 RCI Class B Shares.

Calculation of Exercise Price to Acquire One RCI Class B Share


	(a)	The Optionholder will, on implementation of the Arrangement, receive RCI Options which, if fully exercised, will entitle the Optionholder to acquire 1,000 RCI Class B Shares.

	(b)	The exercise price of such RCI Options is, in the aggregate, $21,250 for 1,000 RCI Class B Shares.

	(c)	Therefore, the exercise price under such RCI Options to acquire one RCI Class B Share will be equal to Cdn.$21,250/1,000, or Cdn.$21.25.

The Board of Directors

Call-Net Enterprises Inc.

2235 Sheppard Avenue East

Toronto, ON M2J 1C6

Dear Sirs:

You have requested our opinion as to the fairness, from a financial point of view, of the Consideration (defined below) being offered to the holders of the common shares (the “Common Shares”) and the class B non-voting shares (the “Non-Voting Shares” and collectively with the Common Shares, the “Call-Net Shares”) of Call-Net Enterprises Inc. (“Call-Net” or the “Company”) pursuant to an arrangement (“Arrangement”) involving the acquisition by Rogers Communications Inc. (“RCI”) of all of the outstanding Call-Net Shares. We understand the Arrangement will be implemented pursuant to section 192 of the Canada Business Corporations Act. Under the terms of the arrangement agreement (“Arrangement Agreement”), holders of Call-Net Shares (“Shareholders”) will receive, for every 4.25 Call-Net Shares, one Class B Non-Voting Share of RCI (“Consideration”). We also understand that among other things, the Arrangement is conditional upon a special resolution (“Resolution”) being supported by Shareholders at a special meeting of shareholders. The terms and conditions necessary to complete the Arrangement, including approvals by Shareholders, are set forth in the Company management information circular.

Engagement of BMO Nesbitt Burns Inc.

The Company has retained BMO Nesbitt Burns Inc. (“BMO Nesbitt Burns”) pursuant to a letter agreement dated May 21, 2004, as subsequently amended, to provide an opinion (the “Opinion”) to the Board of Directors of the Company as to the fairness, from a financial point of view, of the Consideration to the Shareholders.

BMO Nesbitt Burns has not been asked to prepare, and has not prepared, a valuation of Call-Net or RCI or of their respective assets or securities, and as such, our Opinion is not and should not be construed as such a valuation, including a formal valuation for the purposes of Ontario Securities Commission Rule 61-501.

BMO Nesbitt Burns will receive a fixed fee upon delivery of the Opinion, and will receive additional fees if the Arrangement is successfully completed. BMO Nesbitt Burns believes that notwithstanding this fee arrangement, it is independent for purposes of providing this Opinion in connection with the Arrangement. Call-Net has also indemnified BMO Nesbitt Burns in respect of certain liabilities which may be incurred by BMO Nesbitt Burns in connection with the provision of its services.

Our Opinion cannot be made public, in whole or in part, without our prior written consent, except in connection with materials sent to Shareholders in connection with the Arrangement.

Neither BMO Nesbitt Burns nor any of its affiliates is an insider, associate or affiliate (as such terms are defined in the Securities Act (Ontario)) of Call-Net, RCI or any of their respective associates or affiliates.

In the ordinary course of our business, BMO Nesbitt Burns acts as a trader and dealer, both as principal and agent, in all major North American financial markets and, as such, has had or may have positions in the securities of Call-Net or RCI, and from time to time has executed or may execute transactions on behalf of Call-Net or RCI for which it receives compensation. In addition, as an investment dealer, BMO Nesbitt Burns conducts research

E-1

on securities and may, in the ordinary course of its business, provide investment advice to its clients on investment matters, including Call-Net, RCI and their securities.

Credentials of BMO Nesbitt Burns

BMO Nesbitt Burns is one of Canada’s largest investment banking firms, with operations in all facets of corporate and government finance, mergers and acquisitions, equity and fixed income sales and trading, investment research and investment management. The Opinion is the opinion of BMO Nesbitt Burns, and the form and content of the Opinion have been approved for release by a group of its directors and officers and other professionals of BMO Nesbitt Burns, each of whom is experienced in mergers, acquisitions, divestitures and valuation and fairness opinion matters.

Scope of Review

In preparing this Opinion, we have reviewed and/or relied upon, or carried out, among other things, the following:

	viii)	a letter of representation dated as of May 11, 2005 as to certain factual matters, addressed to us, provided by Call-Net’s senior management;

In Respect of RCI:


	ix)	the Annual Reports of RCI for each of the three consecutive fiscal years ended December 31, 2004;

	x)	the Annual Information Forms of RCI for each of the three consecutive fiscal years ended December 31, 2004 and the proxy circulars of RCI for each of the two consecutive fiscal years ended December 31, 2003;

	xi)	the unaudited interim report of RCI for the first quarter of the fiscal year ending December 31, 2005;

	xii)	other public information relating to the business, operations, financial performance and stock trading history of RCI as we considered appropriate in the circumstances;

	xiii)	a discussion with senior management of RCI regarding, among other things, the cable and wireless telecommunications industries, RCI plans to launch a cable-system based telecommunications service, various legal and regulatory matters, and the business, operations, assets, liabilities, financial condition, capital and business prospects of RCI;

E-2

Other:


	xiv)	the Arrangement Agreement dated as of May 11, 2005;

	xv)	information with respect to precedent transactions of a comparable nature that we considered relevant;

	xvi)	public information with respect to the trading values of public companies that we considered relevant; and

	xvii)	such other information, investigations and analyses as we considered necessary or appropriate in the circumstances.

BMO Nesbitt Burns has not, to its knowledge, been denied access by Call-Net to any information requested by BMO Nesbitt Burns.

Assumptions and Limitations

We have relied upon, and have assumed, without independent verification, the completeness, accuracy and fair representation of, all financial and other information, data, advice, opinions and representations obtained by us from public sources or provided to us by Call-Net, RCI or their respective affiliates or advisors or otherwise reviewed by us pursuant to our engagement (the “Information”). The Opinion is conditional upon such completeness, accuracy and fair representation and upon there being no “misrepresentation” (as defined in the Securities Act (Ontario)) in the Information, which we have assumed. In this context, we have assumed that there is no Information relating to the business, operations, assets, liabilities, financial condition, capital or business prospects of Call-Net or RCI that is or could reasonably be expected to be material to the Opinion that has not been publicly disclosed or otherwise disclosed to BMO Nesbitt Burns by Call-Net or RCI, respectively. Senior officers of Call-Net have certified in writing to us that, among other things: since the date of the Information provided to BMO Nesbitt Burns by Call-Net or its advisers (the “Call-Net Information”) there has been no material change, financial or otherwise, in the position of Call-Net or in the assets, liabilities, business or operations of Call-Net, or any change of any material fact that is of a nature as to render any portion of the Call-Net Information material to the Opinion misleading in any material respect, except for changes which have been publicly disclosed; and there are no material facts about Call-Net not disclosed by Call-Net to BMO Nesbitt Burns or not specifically made available to BMO Nesbitt Burns which could reasonably be expected to affect materially the assumptions used, the procedures adopted or the scope of review undertaken by BMO Nesbitt Burns regarding the Opinion. Subject to the exercise of professional judgment, we have not attempted to verify independently the completeness, accuracy or fair representation of any of the Information.

The Opinion is provided to the Board of Directors of the Company in its consideration of the Arrangement and may not be relied upon by any other person. BMO Nesbitt Burns disclaims any undertaking or obligation to advise any person of any change in any fact or matter affecting the Opinion which may come or be brought to the attention of BMO Nesbitt Burns after the date hereof. Without limiting the foregoing, in the event that there is any material change in the business or affairs of the Company or in the Information after the date hereof which materially affects the Opinion or if BMO Nesbitt Burns becomes aware of any information not disclosed to us, which would make the Information misleading in any material respect, untrue or inaccurate, or would result in a misrepresentation in the Information, BMO Nesbitt Burns is entitled to amend, supplement or withdraw the Opinion. The Opinion is not intended to be and does not constitute a recommendation to any shareholder to vote for or against the Resolution.

Our Opinion is not, and should not be construed as, advice as to the price at which shares of Call-Net or RCI may trade (before or after completion of the Arrangement) at any future date.

BMO Nesbitt Burns was not requested to, and it did not, solicit or consider any third party indications of interest in the possible acquisition of shares of Call-Net or any other transaction involving Call-Net, its assets or its securities. Our Opinion does not address the relative merits of the Arrangement as compared to any other possible transaction for the acquisition of shares of Call-Net or any other possible transaction involving Call-Net, its assets or its securities.

E-3

The Opinion is rendered on the basis of securities markets, economic and general business and financial conditions prevailing as at the date hereof and the condition and prospects, financial and otherwise, of Call-Net and RCI as reflected in the Information. In our analyses and in connection with the preparation of the Opinion, we made numerous assumptions with respect to industry performance, general business, market and economic conditions and other matters, many of which are beyond the control of any party involved in the transaction.

Fairness Conclusion

Based upon and subject to the foregoing, it is our opinion that as of the date hereof the Consideration is fair, from a financial point of view, to the Shareholders.

Yours truly,

“BMO Nesbitt Burns Inc.”

BMO Nesbitt Burns Inc.

Recalculated the application of the pro forma adjustments to the aggregate of the amounts in the columns captioned “RCI” and “Call-Net” as at March 31, 2005 and for the three months then ended, and the application of the pro forma adjustments to the aggregate of the amounts in the columns captioned “RCI” and “Call-Net” for the year ended December 31, 2004 and “Microcell – Nine Months ended September 30, 2004” for the nine months ended September 30, 2004, and found the amounts in the columns captioned “Pro forma Total” to be arithmetically correct.

A pro forma financial statement is based on management assumptions and adjustments which are inherently subjective. The foregoing procedures are substantially less than either an audit or a review, the objective of which is the expression of assurance with respect to management’s assumptions, the pro forma adjustments, and the application of the adjustments to the historical financial information. Accordingly, we express no such assurance. The foregoing procedures would not necessarily reveal matters of significance to the pro forma financial statements, and we therefore make no representation about the sufficiency of the procedures for the purposes of a reader of such statements.

COMMENTS FOR U.S. READERS ON DIFFERENCES BETWEEN

CANADIAN AND U.S. REPORTING STANDARDS

The above report, provided solely pursuant to Canadian requirements, is expressed in accordance with standards of reporting generally accepted in Canada. To report in conformity with United States standards on the reasonableness of the pro forma adjustments and their application to the pro forma financial statements requires an examination or review substantially greater in scope than the review we have conducted. Consequently, we are unable to express any opinion in accordance with standards of reporting generally accepted in the United States with respect to the compilation of the accompanying unaudited pro forma financial information.

NOTES TO PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Tabular amounts in thousands, except per share amounts)

Year ended December 31, 2004 and three months ended March 31, 2005

(Unaudited)

1. Description of transactions:

On September 13, 2004, Rogers Communications Inc. (“RCI”) entered into an agreement with JVII General Partnership (“JVII”), a general partnership wholly owned by AT&T Wireless Services, Inc., whereby RCI agreed to purchase all of JVII’s shares of Rogers Wireless Communications Inc. (“RWCI”) for a cash purchase price totalling approximately $1.767 billion (the “AWE Acquisition”). RCI closed this transaction on October 13, 2004.

On September 20, 2004, Rogers Wireless Inc. (“RWI”), a wholly owned subsidiary of RWCI, announced an agreement with Microcell Telecommunications Inc. (“Microcell”) to make an all cash tender offer totalling approximately $1.3 billion, to acquire all of Microcell, Canada’s fourth largest wireless communications provider (the “Microcell Acquisition”). RWI completed the Microcell Acquisition on November 12, 2004.

On November 11, 2004, RCI launched an exchange offer to purchase all of the outstanding RWCI Class B Restricted Voting shares (“RWCI Class B Shares”) not already owned by RCI in exchange for 1.75 RCI Class B Non-Voting shares for each RWCI Class B Share (the “Exchange Offer”). RCI completed the Exchange Offer on December 31, 2004.

In connection with the AWE Acquisition and the Microcell Acquisition, RWI announced on November 19, 2004 that it had priced a private placement of notes in the aggregate principal amount of U.S. $2,356,000,000 (approximately $2,807,000,000) (the “Financing”).

On May 11, 2005, RCI announced an agreement to acquire 100% of Call-Net Enterprises Inc. (“Call-Net”), a Canadian telecommunications solutions provider. Under the terms of the agreement, Call-Net shareholders will receive one RCI Class B Non-Voting share for each 4.25 outstanding shares of Call-Net (the “Call-Net Acquisition”). The Call-Net Acquisition is subject to court, regulatory and Call-Net shareholder approval and is expected to be completed in July 2005.

2. Basis of presentation:


(a)	Pro forma condensed consolidated financial statements:

The accompanying unaudited pro forma condensed consolidated financial statements (the “Statements”) give effect to the AWE Acquisition, the Microcell Acquisition, the Exchange Offer and the Financing as if they had occurred as at January 1, 2004 for the purposes of the unaudited pro forma condensed consolidated statement of income for the year ended December 31, 2004. For purposes of the unaudited pro forma consolidated balance sheet at March 31, 2005 and the unaudited pro forma condensed consolidated statement of income for the three months ended March 31, 2005, these transactions are already included in the consolidated financial statements of RCI as at and for the three months ended March 31, 2005.

The Statements give effect to the Call-Net Acquisition as if it had occurred as at:


	•	March 31, 2005 for the purpose of the unaudited pro forma consolidated balance sheet; and

	•	January 1, 2004 for the purposes of the unaudited pro forma condensed consolidated statements of income for the year ended December 31, 2004 and the three months ended March 31, 2005.

The Statements have been prepared by management in accordance with Canadian generally accepted accounting principles (“GAAP”). The accounting policies used in the preparation of the Statements are consistent with those used by RCI in the preparation of the consolidated financial statements for the year ended December 31, 2004 and the three months ended March 31, 2005.

G-6

The Statements have been prepared using the following information and should be read in conjunction with the financial statements listed below:


	(i)	Audited consolidated financial statements of RCI as at and for the year ended December 31, 2004;

	(ii)	Audited consolidated financial statements of Call-Net as at and for the year ended December 31, 2004;

	(iii)	Unaudited consolidated interim financial statements of RCI as at and for the three months ended March 31, 2005;

	(iv)	Unaudited consolidated interim financial statements of Call-Net as at and for the three months ended March 31, 2005;

	(v)	Unaudited consolidated interim financial statements of Microcell as at and for the nine months ended September 30, 2004; and

	(vi)	Such other supplementary information as was considered necessary to reflect the AWE Acquisition, the Microcell Acquisition, the Exchange Offer, the Financing and the Call-Net Acquisition in the Statements.

The Statements do not include the anticipated financial benefits from such items as cost savings arising from the AWE Acquisition, the Microcell Acquisition, the Exchange Offer and the Call-Net Acquisition. The Statements are not necessarily indicative of the results of operations or the financial position that would have resulted had the AWE Acquisition, Microcell Acquisition, the Exchange Offer, the Financing or the Call-Net Acquisition been effected on the dates indicated, or the results that may be obtained in the future.

Certain elements of RCI’s, Microcell’s and Call-Net’s consolidated financial statements have been reclassified to provide a consistent classification format.


(b)	Microcell special charges:

In connection with events leading up to the Microcell Acquisition, Microcell incurred financial and legal fees and the vesting of options under Microcell’s stock option plan was accelerated, which resulted in an acceleration of compensation expense. As a result, Microcell incurred approximately $9.7 million and $26.1 million of special charges in the nine months ended September 30, 2004 and the period from October 1 to November 8, 2004, respectively.


3.	Pro forma assumptions and adjustments — AWE Acquisition and Exchange Offer:

The unaudited pro forma condensed consolidated statement of income for the year ended December 31, 2004 incorporates the following adjustments:


	(a)	Pro forma operating expenses for the year ended December 31, 2004 have been increased by $5,063,000 representing the compensation cost of the RCI stock options issued to holders of RWCI stock options in the Exchange Offer.

	(b)	Pro forma depreciation and amortization has been increased by $194,772,000 for the year ended December 31, 2004 to reflect the amortization of other intangible assets arising on the AWE Acquisition and the Exchange Offer.

	(c)	Pro forma interest expense for the year ended December 31, 2004 has been decreased by $12,240,000 to reflect the amortization of the fair value adjustments to RWCI’s long-term debt and derivative instruments arising on the AWE Acquisition and the Exchange Offer.

	(d)	Non-controlling interest of $79,581,000 for the year ended December 31, 2004 has been eliminated.

G-7


4.	Pro forma assumptions and adjustments — Microcell Acquisition:

The unaudited pro forma condensed consolidated statement of income for the year ended December 31, 2004 incorporates the following adjustments:


	(a)	RCI recognizes certain revenue and expense items, related primarily to the sale of prepaid airtime and subscriber acquisition and retention costs, on a different basis than Microcell. As a result, the following adjustments to revenue and expenses are required to harmonize Microcell’s accounting presentation in the nine months ended September 30, 2004 to that of RCI:


	Year ended
	December 31,
Increase (decrease)	2004

Operating revenue	$	(8,940	)
Operating expenses		22,761


	In addition, certain items in Microcell’s interest on long-term debt and other income (loss) aggregating $2,558,000 have been reclassified to provide a consistent classification format.


	(b)	Pro forma depreciation and amortization has been increased by $80,332,000 for the year ended December 31, 2004 to reflect the amortization of intangible assets arising on the Microcell Acquisition.

	(c)	Pro forma amortization expense has been reduced by $7,552,000 for the year ended December 31, 2004 to reflect the elimination of historical amortization expense as a result of the fair value adjustments to the existing Microcell intangible assets upon acquisition.

	(d)	Pro forma depreciation expense has been reduced by $25,826,000 for the year ended December 31, 2004 to reflect the elimination of historical depreciation expense as a result of the write-down of Microcell’s property, plant and equipment to estimated fair value.


5.	Pro forma assumptions and adjustments — Financing:

The unaudited pro forma condensed consolidated statement of income for the year ended December 31, 2004 incorporates the following adjustments:


	(a)	Interest expense and other income have been adjusted to reflect the Financing and to eliminate the historical interest expense of Microcell as a result of the repayment of Microcell’s long-term debt, as follows:


		Year ended
		December 31,
Increase (decrease)		2004

Interest expense:
	RWI senior and subordinated debt	$	191,235
	Microcell long-term debt		(23,852	)

		$	167,383

Other income		$	9,611


	Pro forma interest expense for the year ended December 31, 2004 has been determined using actual interest rates for the RWI fixed rate senior and subordinated debt and an average interest rate of 4.66% for the RWI floating rate senior debt. Interest expense denominated in U.S. dollars has been converted to Canadian dollars at the average foreign exchange rate for the period.

	A change of ¹/8% in the interest rate on the RWI floating rate senior debt would impact the pro forma interest expense and pro forma loss by approximately $900,000 for the year ended December 31, 2004.

G-8


	(b)	Pro forma depreciation and amortization has been increased by $3,443,000 for the year ended December 31, 2004 to reflect the amortization of financing costs incurred on the issue of RWI senior and subordinated debt over the average term to maturity.


6.	Accounting for the Call-Net Acquisition:

The Call-Net Acquisition is accounted for using the purchase method of accounting. The total purchase consideration is comprised of the following:


8,419,832 RCI Class B Non-Voting shares	$	314,312
Stock options, at fair value		7,933
Estimated transaction costs		3,000

	$	325,245

For accounting purposes, the value of the RCI Class B Non-Voting shares was calculated as the average price over a period of two days before and after the May 11, 2005 announcement date of the Call-Net Acquisition.

The purchase price will be allocated to the assets acquired (including identifiable intangible assets arising from the purchase) and liabilities assumed based on their estimated fair value at the date of acquisition.

Details of the estimated fair value of assets acquired and liabilities assumed of Call-Net based on the information available at the date of preparation of the Statements are as follows:


Assets acquired:
	Cash and cash equivalents	$	27,600
	Short-term investments		52,000
	Accounts receivable		22,400
	Other current assets		25,900
	Property, plant and equipment		437,400
	Other intangible assets		176,660
	Goodwill		54,675
	Other long-term assets		5,600

			802,235
Less liabilities assumed:
	Accounts payable and accrued liabilities		132,900
	Liabilities set up on close (note 7(a)(i))		8,000
	Long-term debt		283,290
	Other long-term liabilities		52,800

			476,990

Fair value of net assets acquired		$	325,245

The actual adjustments that will ultimately be made in finalizing the allocation of the purchase price of Call-Net to the fair value of the net assets acquired will depend on a number of factors including additional information available at such time, changes in market values and changes in Call-Net’s operating results between the date of the Statements and the effective date of the Call-Net Acquisition.

In the preparation of the Statements, the purchase consideration has been allocated on a preliminary basis to the fair value of assets acquired and liabilities assumed based on management’s best estimates and taking into account all relevant information available at the time the Statements were prepared. Management expects that the actual amounts for each of the fair values of the assets and liabilities acquired will vary from the pro forma amounts and that the variation may be material.

G-9


7.	Pro forma assumptions and adjustments — Call-Net Acquisition:


	(a)	The unaudited pro forma consolidated balance sheet as at March 31, 2005 incorporates the following adjustments:


	(i)	In connection with the Call-Net Acquisition, it is expected that severance and other employee related costs totalling an estimated $8,000,000 will be incurred in accordance with certain employment contracts. These costs are management’s preliminary estimates and take into account all relevant information available at the time the Statements were prepared. The actual costs may vary materially from such estimates. These costs have been reflected in the pro forma consolidated balance sheet as a liability as part of the purchase consideration allocation.

	(ii)	Upon acquisition, all of the Call-Net deferred charges and intangible assets have been written off. Intangible assets arising on the Call-Net Acquisition have been recorded at their estimated fair values as part of the allocation of the purchase price. Intangible assets acquired include Call-Net’s customer relationships. In addition, long-term debt has been adjusted to estimated fair value. The estimated fair values are based on management’s best estimates. The estimated value allocated to goodwill was based on the residual of the preliminary fair values of the identifiable tangible and intangible assets less the fair values of the liabilities assumed. The actual allocation may differ significantly from these estimates.

	(iii)	Upon completion of the Call-Net Acquisition, Call-Net is required to commence an offer to purchase all of its outstanding senior secured notes at a purchase price of 101% of their principal amount plus accrued interest. Any amounts purchased are expected to be financed by RCI using existing long-term bank credit facilities and therefore the Call-Net senior secured notes are classified as long-term debt for purposes of the unaudited pro forma consolidated balance sheet at March 31, 2005.

	(iv)	A full valuation allowance has been recorded against the income tax loss carryforwards of Call-Net totalling approximately $1.2 billion as it is not “more likely than not” that these losses will be utilized. Any future reduction in the valuation allowance will reduce goodwill and other intangible assets.

	(v)	Call-Net’s shareholders’ equity has been eliminated to reflect the effect of the Call-Net Acquisition.


	(b)	The unaudited pro forma condensed consolidated statements of income for the year ended December 31, 2004 and for the three months ended March 31, 2005 incorporate the following adjustments:


	(i)	Intercompany revenue between Microcell and Call-Net in the aggregate amounts of $14,504,000 and $2,537,000 for the year ended December 31, 2004 and the three months ended March 31, 2005, respectively, has been eliminated, with an offsetting adjustment to operating expenses.

	(ii)	Pro forma depreciation and amortization has been increased by $35,332,000 and $8,833,000 for the year ended December 31, 2004 and the three months ended March 31, 2005, respectively, to reflect the amortization of other intangible assets arising on the Call-Net Acquisition, being the Call-Net customer relationships, over an estimated average life of five years on a straight-line basis. The five-year estimated average life was determined based on Call-Net’s historical customer relationship period. A change in the fair value of other intangible assets acquired of $10,000,000 would impact the pro forma amortization expense and pro forma net loss by $2,000,000 and $500,000 for the year ended December 31, 2004 and the three months ended March 31, 2005, respectively. An extension in the estimated average useful life of the Call-Net customer relationships by one year would reduce the pro forma depreciation and amortization expense and pro forma net loss by $5,889,000 and $1,472,000 for the year ended December 31, 2004 and the three months ended March 31, 2005, respectively.


	Pro forma amortization expense has been reduced by $30,000,000 and $8,100,000 for the year ended December 31, 2004 and the three months ended March 31, 2005, respectively, to reflect

G-10


	the elimination of historical amortization expense as a result of the fair value adjustments to the existing Call-Net intangible assets upon acquisition.


	(iii)	Pro forma interest expense has been decreased by $2,698,000 and $675,000 for the year ended December 31, 2004 and the three months ended March 31, 2005, respectively, to reflect the amortization of the fair value adjustments to Call-Net’s long-term debt.

For the year ended December 31, 2004 and the three months ended March 31, 2005, the effect of potentially dilutive securities, including employee stock options and the RCI convertible debentures, was excluded from the computation of diluted earnings per share as their effect is anti-dilutive.
