Call-Net Board Recommends Shareholders Accept Rogers' Offer of One RCI

Share for Each 4.25 Call-Net Shares

TORONTO, May 11 /CNW/ - Rogers Communications Inc. ("RCI" or "Rogers")

and Call-Net Enterprises Inc. ("Call-Net") today jointly announced that they

have entered into a definitive agreement under which RCI will acquire 100% of

Call-Net in a share for share transaction under a plan of arrangement.

Under the terms of the agreement, Call-Net Common and Class B

shareholders will receive a fixed exchange ratio of one RCI Class B Non-voting

share for each 4.25 outstanding shares of Call-Net, representing a fully

diluted equity value of approximately $330 million. In total, it is expected

that upon closing of the transaction approximately 9.0 million RCI Class B

Non-voting shares will be issued representing approximately 3.2% of the pro

forma shares outstanding. Based upon the May 10, 2005 closing price of the RCI

Class B Non-voting shares, the transaction values Call-Net at approximately

$8.71 per share. At March 31, 2005, Call-Net had senior secured notes due 2008

of $269.8 million outstanding and cash and short-term investments of

$79.6 million.

"This acquisition will significantly jumpstart and expand our ability to

provide customers with a full suite of service solutions that deliver the

simplicity, quality and value they want in one package, on one bill, from one

provider," said Ted Rogers, President and CEO of Rogers Communications Inc.

"This positions us immediately to offer primary line telephone service across

our residential and business bases of wireless and cable customers. It also

provides a substantial additional base of customers to cross-sell our

portfolio of communications and entertainment products and a skilled and

knowledgeable employee group with strengths in telephony sales and marketing.

As Rogers' cable telephony service is deployed on a market by market basis, we

will be able to migrate Call-Net customers in our Rogers Cable territory to

our advanced digital cable telephony platform when advantageous."

"This is a terrific day for Call-Net customers, shareholders, employees,

and for Canadian telecom in general," said Bill Linton, President and CEO of

Call-Net. "We share a common heritage with Rogers as a catalyst in bringing

competition to the Canadian communications markets. By joining our business

with one of the foremost Canadian names in communications, entertainment and

information services, Call-Net customers will have a greatly enhanced

selection of advanced services to choose from in their homes and businesses

and the ability to enjoy the convenience of complete multi-product bundles

from a single provider. The combination of Rogers' innovative offerings and

high quality wireless and cable networks will bring tremendous additional

choice and value to our customers."

"This transaction offers an opportunity to acquire a significant customer

base and telecom assets that together provide network and operating cost

synergies and sales opportunities, which makes the transaction attractive

economically as well as strategically," added Ted Rogers. "This will

complement our deployment of an advanced broadband IP multimedia network to

support digital voice-over-cable telephony and other new voice and data

services across the Rogers Cable service areas and expand the base of

customers that will benefit from them."

Call-Net, through its Sprint Canada subsidiary and with approximately

1,800 employees, provides home phone and local business service, IP data, long

distance and wireless services to approximately 600,000 consumers and business

customers across Canada, the majority of which are concentrated in areas

served by Rogers Cable. Call-Net owns a 14,000 route kilometre North American

transcontinental fibre optic broadband network that spans across Canada and

connects all major cities and into main U.S. voice and data network access and

peering points. Call-Net also has more than 150 central office co-location

points in all of Canada's largest markets as well as options to acquire

significant CLEC assets, including extensive local fibre in eastern Canada,

most of which are within Rogers Cable's serving areas. Call-Net's wireless

services are offered to its customers, alone and in bundles with other voice

services, through a wholesale agreement with Rogers' Fido division.

Rogers anticipates that it will realize cost savings from the

transaction, including reduced payments to incumbent and other telecom

providers. The reduction in costs currently incurred by Sprint Canada, Rogers

Wireless and Rogers Cable include the areas of local and long haul

interconnection, the rental of local loops and transport, Internet and other

data transport costs, and the costs associated with the transport of local and

long haul wireless traffic.

The boards of directors of Rogers and Call-Net have approved the

transaction, with the members of the Call-Net Board having agreed that the

transaction is fair to their shareholders and that they will recommend that

the Call-Net shareholders approve the transaction at a Call-Net shareholder

meeting expected to be held before June 30, 2005.

BMO Nesbitt Burns is acting as financial advisor to Call-Net on this

transaction and has provided Call-Net's Board of Directors with a fairness

opinion that the consideration to be received under the Plan of Arrangement is

fair, from a financial point of view, to the shareholders of Call-Net. Scotia

Capital is acting as financial advisor to Rogers on this transaction.

Subject to certain customary conditions, including among others,

regulatory approvals and acceptance by Call-Net shareholders representing at

least two-thirds of the votes cast in respect of the Plan of Arrangement, this

transaction is expected to close during the third quarter of 2005. The

transaction is expected to be accounted for as a purchase and it is

anticipated that the share-for-share exchange will be structured as tax-free

to eligible Canadian shareholders. Call-Net has agreed not to solicit or take

certain other actions with respect to any competing proposal, and in addition

has agreed to pay Rogers a termination fee of $10 million under specified

conditions.

A proxy circular relating to the transaction is expected to be sent to

Call-Net's shareholders prior to the end of May 2005. Investors are urged to

read the proxy circular regarding the transaction when it becomes available,

as it will contain important information.

The proxy circular and the arrangement agreement will be filed in Canada
