financial support and to register any securities on the books of TSN Canada Holdings and TSN Canada. Such appointment and power of attorney, being coupled with an interest, shall not be revoked by the insolvency, bankruptcy, dissolution, liquidation or other termination of the existence of TSN Canada Holdings or TSN Canada and each of TSN Canada Holdings and TSN Canada hereby ratifies and confirms all that TSN US may lawfully do or cause to be done by virtue of the provisions of this Section 4.3.

Operating Cash Shortfall

(a)

Notwithstanding anything to the contrary in this Agreement, in the event that at any time (but not more often than once per month) either TSN Canada Holdings or TSN Canada incurs or expects to incur an Operating Cash Shortfall, it may request in writing, by the delivery of a notice to TSN US, financial support from TSN US in an amount equal to such Operating Cash Shortfall. The notice requesting financial support shall also specify the form and the terms for such financial support which TSN Canada Holdings or TSN Canada wishes to receive: including, without limitation, support by way of the purchase by TSN US of shares of TSN Canada Holdings or TSN Canada, or a loan to TSN Canada Holdings or TSN Canada (which loan may be convertible into equity of TSN Canada Holdings or TSN Canada). If TSN Canada Holdings or TSN Canada and TSN US are unable to agree on the form or terms of financial support to be provided within ten (10) Business Days following the date that the request for financial support is made, then the request for financial support shall, subject to the Restrictions, be deemed to be a request for financial support by the purchase by TSN US of non-voting common shares of TSN Canada Holdings or TSN Canada at a price of $1.00 per share. Such non-voting common shares shall rank pari passu with the TSN Canada Holdings Common Shares or TSN Canada Common Shares, as the case may be.

(b)

Within fifteen (15) Business Days following receipt by TSN US of such request and such other documentation as is reasonably required by TSN US concerning such Operating Cash Shortfall, TSN US shall provide the financial support requested. Notwithstanding the foregoing, TSN US shall not be obligated to provide the financial support unless all of the following conditions are met:

(i)

the provision of the financial support shall not result in TSN Canada failing to comply with the Restrictions;

(ii)

the Business Plan of TSN Canada and TSN Canada Holdings in effect at the time of the request for financial support, and for the two preceding financial years, must be reasonably acceptable to TSN US; and

(iii)

TSN Canada and TSN Canada Holdings must have conducted their business in material compliance with their respective Business Plans in effect at the time of the request for financial support and for the two preceding financial years.

(c)

For purposes of this Section 4.4, “Operating Cash Shortfall” means a cash shortfall arising in the ordinary course of Business and includes any cash required for the payment of any taxes attributable to the operations or activities of TSN Canada Holdings or TSN Canada but which, for greater certainty, does not include cash needs arising from any extraordinary loss, any writedown of assets or any cash needs arising from an action which constitutes a breach by TSN Canada Holdings or TSN Canada of this Agreement.

(d)

TSN US’ obligations to provide financial support for Operating Cash Shortfalls of TSN Canada Holdings or TSN Canada pursuant to this Section 4.4 shall terminate upon the earlier of: (i) the termination of this Agreement; or (ii) a change of control of TSN Canada provided that the transfer by TMI to a BCE Group Member in a manner permitted by Section 6.1(d) hereof, shall not constitute a change of control of TSN Canada. The Parties acknowledge and agree that TSN US’ obligations to provide financial support for such Operating Cash Shortfalls shall apply to all Operating Cash Shortfalls incurred prior to the termination of TSN US’ obligations hereunder and shall be satisfied in full, notwithstanding that the Parties may receive notice of such Operating Cash Shortfalls, including tax liabilities and payments, after the termination of TSN US’ obligations to provide financial support for Operating Cash Shortfalls of TSN Canada Holdings and TSN Canada.

6.1

Restrictions on Transfer of Shares

(a)

Any transfer of Shares of TSN Canada Holdings or of TSN Canada must be in compliance with all Canadian laws, including the Restrictions.

(b)

Except as expressly provided in this Agreement or in any other agreement between the Shareholders, or as may otherwise be provided in the articles of TSN Canada or TSN Canada Holdings, as applicable, or agreed to in writing by the Shareholders, no Shareholder shall, directly or indirectly, sell, transfer, or create any Lien on (collectively, “transfer”) any Shares held by it, or any of its rights or obligations under this Agreement or any voting rights with respect to its Shares, to any Person, except with the consent of all of the Shareholders.

(c)

Any transfer in violation of this Agreement shall be void and shall not be recorded on the books or records of TSN Canada Holdings or TSN Canada.

(d)

A BCE Group Member shall be permitted to transfer all or part of its Shares of TSN Canada Holdings to another BCE Group Member. The transferring BCE Group Member shall give not less than ten (10) Business Days prior written notice of any such transfer to TSN US. TSN US and the BCE Group Members who own Shares of TSN Canada Holdings at the time will use Best Efforts to obtain as soon as possible all of the approvals or deemed approvals and effect all notifications and other compliance required by the Canadian Communications Statutes and the statutes referred to in Section 7.1(c) and by the Federal Communications Commission in respect of such transfer of Shares of TSN Canada Holdings. In the event any such transferee under this Section 6.1(d) ceases to qualify as a BCE Group Member and such transferee is not reasonably acceptable to TSN US and to the Canadian regulatory authorities, then such entity shall immediately (or if any regulatory approvals are required, within ten (10) days of receipt thereof) transfer the Shares to a BCE Group Member, and if such Shares are not so transferred, the loss of status as a BCE Group Member shall thereupon be deemed a transfer in violation of this Agreement, and the provisions of Section 6.1(c) shall apply.

(e)

If (i) any company that directly or indirectly owns or Controls a BCE Group Member wishes to transfer all or part of its interest in such BCE Group

Member to a third party other than a BCE Group Member or a Person that as a result of the transfer becomes a BCE Group Member, and (ii) at the time of such proposed transfer such BCE Group Member owns Shares of TSN Canada Holdings, the BCE Group Member shall forthwith give notice (the “TMI Notice”) to TSN US of such proposed transfer and TSN US and/or any of its Affiliates shall be entitled, subject to the Restrictions, to purchase, or designate and cause an Eligible Purchaser to purchase all but not less than all of the Shares of TSN Canada Holdings owned by the BCE Group Members. If TSN US and/or any of its Affiliates wish to exercise the right to purchase provided for in this Section (which right is hereinafter referred to as the “TSN US ROFR”), TSN US shall give notice to the BCE Group Member that gave the TMI Notice and BCE Inc. within thirty (30) days of its receipt of the TMI Notice, advising them of its intention to exercise such rights under this Section. The price to be paid for each BCE Group Member’s Shares of TSN Canada Holdings pursuant to this Section shall be the stated capital of such Shares. The purchase and sale of the Shares pursuant to the exercise of the TSN US ROFR shall be completed on the date (the “Closing Date”) which is the fifth day following the later of the delivery by TSN US of its notice and receipt of all governmental approvals, if any, required in connection with such purchase, which Closing Date shall not be later than twelve (12) months after the date of the TMI Notice. TSN US and the BCE Group Members who own Shares of TSN Canada Holdings at the time (and in the case of Section 6.1(e)B, the Person that owns Shares in TSN Canada Holdings and that has lost its status as a BCE Group Member thereby giving rise to TSN US’ exercise of the TSN US ROFR under that Section) will use Best Efforts to obtain as soon as possible all of the approvals or deemed approvals and effect all notifications and other compliance required by the Canadian Communications Statutes and the statutes referred to in Section 7.1(c) and by the Federal Communications Commission (which, for greater certainty, does not include any financial, performance or other obligations on the BCE Group Members following the completion of the purchase and sale of the Shares). TSN US will, if applicable, use Best Efforts to identify an Eligible Purchaser and the BCE Group Members will use commercially reasonable efforts to assist in identifying such an Eligible Purchaser, in respect of such transfer of Shares of TSN Canada Holdings pursuant to TSN US’ exercise of the TSN US ROFR. If an Eligible Purchaser is designated to purchase such Shares it shall do so on such terms as the Eligible Purchaser and TSN US may agree; provided that the purchase price shall not be less than the stated capital of such Shares.

Notwithstanding Section 6.1(e)A., any Person that has an interest in TMI (a “TMI Parent”) at a time when TMI owns a majority of the Shares of TSN Canada Holdings will be entitled, after giving notice to the other Shareholders, subject to the Restrictions, to sell or transfer all or part of its interest in TMI to any BCE Group Member, and in such circumstances, TSN US shall not have the right to exercise the TSN US ROFR, provided, that in the event any such transferee of the TMI Parent ceases to qualify as a BCE

Group Member and the change of Control of TMI resulting in such disqualification is not reasonably acceptable to TSN US and to the Canadian regulatory authorities, then such entity shall immediately (or if any regulatory approvals are required, within ten (10) days of receipt thereof) transfer the Shares to a BCE Group Member, and if such Shares are not so transferred, the loss of status as a BCE Group Member shall thereupon be deemed a transfer in violation of this Agreement, and the provisions of Section 6.1(c) shall apply, provided further, that, notwithstanding the foregoing, at any time after the date that a transferee of the TMI Parent under this Section 6.1(e)B. ceases to be a BCE Group Member, TSN US may, by written notice to TMI and BCE Inc., elect to exercise the TSN US ROFR in which case the provisions of Section 6.1(e)A. shall apply.

Notwithstanding any other provision of this Agreement, no entity that directly or indirectly owns or Controls TMI will, prior to January 1, 2009, transfer its interest in TMI to a third party other than another BCE Group Member if, at the time of such transfer, TMI owns a majority of the Shares of TSN Canada Holdings.

(f)

TSN US shall be permitted to (i) transfer to any lender, and create a Lien upon, some or all of its Shares in connection with any financing transaction, and any such transfer and lender transferee shall be deemed to have been consented to and accepted by TMI and any other BCE Group Member that owns Shares of TSN Canada Holdings, provided, that any subsequent transfer of any Shares by such lender transferee shall require the approval of TMI hereunder, which approval shall not be unreasonably withheld or delayed, and (ii) transfer all or part of its Shares of TSN Canada Holdings and/or TSN Canada to (A) an Affiliate of TSN US or any Person that is Controlled by any such Affiliate; provided, that in the event any such transferee of TSN US ceases to qualify as an Affiliate of TSN US or otherwise ceases to be Controlled by any such Affiliate, then such entity promptly shall transfer the Shares back to TSN US or an Affiliate of TSN US or any Person that is Controlled by any such Affiliate, and if such Shares are not so transferred, the loss of status as an Affiliate of TSN US or otherwise ceasing to be Controlled by any such Affiliate shall thereupon be deemed a transfer in violation of this Agreement, and the provisions of Section 6.1(c) shall apply or (B) a transferee that is not an Affiliate of TSN US or a Person that is not Controlled by any such Affiliate, provided that such transferee specified in (B) is reasonably acceptable to TMI.

(g)

It is a condition of the transfer of Shares to any Person that is permitted under this Agreement that the transferee execute and deliver a signature page to this Agreement pursuant to which such transferee becomes a party to this Agreement and otherwise agrees to be subject to all of the rights and obligations of the transferor (or otherwise applicable to the transferee) hereunder. Following the transfer of the Shares and the execution and delivery by the transferee of the signature page to this Agreement as aforesaid, the transferor shall cease to be subject to the rights and obligations hereunder, provided that the obligations of any transferor under Section 11.1 hereof and the last two sentences of this Section 6.1(g), as applicable, shall continue in full

force and effect against any transferor of Shares under the terms of this Agreement. Furthermore, TSN US agrees that in the event that a transferee referred to in Section 6.1(f)(ii)(A) ceases to qualify as an Affiliate of TSN US or otherwise ceases to be Controlled by any such Affiliate, and the transferee is thereupon obliged to transfer the Shares to TSN US or an Affiliate of TSN US or any Person that is Controlled by any such Affiliate as contemplated in Section 6.1(f)(ii)(A), TSN US shall either acquire the Shares or shall cause an Affiliate or a Person controlled by an Affiliate to do so. Furthermore, BCE Inc. agrees that (i) in the event that a transferee referred to in Section 6.1(d) ceases to qualify as a BCE Group Member and such transferee is not reasonably acceptable to TSN US and to the Canadian regulatory authorities, and the transferee is thereupon obliged to transfer the Shares to a BCE Group Member as contemplated in the last sentence of Section 6.1(d), BCE Inc. shall either acquire the Shares or cause a BCE Group member to do so, and (ii) in the event a transferee of the TMI Parent referred to in Section 6.1(e)(B) ceases to qualify as a BCE Group Member and the change of Control of TMI resulting in such disqualification is not reasonably acceptable to TSN US and to the Canadian regulatory authorities, and the transferee is thereupon obliged to transfer the Shares to a BCE Group member as contemplated in the last sentence of Section 6.1(e)(B), BCE Inc. shall either acquire the Shares or cause a BCE Group member to do so.

all of the TSN Canada Holdings Common Shares held by such BCE Group Members and, upon the giving of such notice, the designated Eligible Purchaser shall thereupon be obligated to purchase from them all of such TSN Canada Holdings Common Shares. The obligations of TSN US hereunder shall continue in effect notwithstanding any such designation of an Eligible Purchaser as permitted in this Section 6.2(b.1).

Confidentiality

(a)

Each of the Parties agrees that it shall not, at any time or under any circumstances, without the unanimous consent of the Shareholders and of TSN Canada Holdings or TSN Canada, as applicable, directly or indirectly communicate or disclose to any Person (other than the other Parties and their employees, agents, advisors and representatives) or make use of (except in connection with its interest in TSN Canada Holdings or TSN Canada) any confidential knowledge or information howsoever acquired by such Party relating to or concerning the customers, suppliers, products, technology, trade secrets, systems or operations, or other confidential information regarding the property, Business and affairs, of TSN Canada Holdings or TSN Canada, (herein referred to as “Confidential Information”). Notwithstanding the foregoing, Confidential Information shall not include, and the restriction in the foregoing sentence shall not apply to the following:

(i)

information which is known by such Person or becomes known to such Person without breach of a confidentiality obligation or which is or becomes generally available to the public (other than by disclosure by such Party or its employees, agents, advisors or representatives contrary to this Section); or

(ii)

information which is reasonably required to be disclosed by a Party to protect its interests in connection with any valuation or legal proceeding under this Agreement; or

(iii)

information which is required to be disclosed by law or by the applicable regulations or policies of any regulatory agency of competent jurisdiction (including Industry Canada and/or the CRTC) or any stock exchange, provided that the disclosing Party shall provide the other Shareholder(s) with the opportunity to review and comment on such disclosure and will attempt to obtain confidential treatment for such disclosure and/or a protective order if reasonably requested by the other Shareholders; or

(iv)

information disclosed to a third party for purposes consistent with a business plan developed in accordance with Section 5.8 above, and provided that such third party has entered into a confidentiality agreement with the disclosing party.

(b)

Each of the Parties acknowledges that disclosure of any Confidential Information in contravention of this Section may cause significant harm to the other Parties and that remedies at law may be inadequate to protect against a breach of this Section. Accordingly, each of the Parties agrees that each of the other Parties shall be entitled, in addition to any other relief available to it, to the granting of injunctive relief without proof of actual damages or the requirement to establish the inadequacy of any of the other remedies available to it. Each of the Parties covenants not to assert any defence in proceedings regarding the granting of an injunction or specific performance based on the availability to it of any other remedy.

11.2

Relationship of the Parties, etc.

TSN Canada Holdings and TSN Canada agree that they will not engage in any business, directly or indirectly, that directly competes with the business of TSN US conducted in the United States (whether as conducted at the date hereof or as TSN US conducts or plans to conduct in the future, as the case may be).

Nothing contained herein shall be construed to create a partnership, agency or other similar relationship of any type between any or all of the Parties or to limit in any manner the Parties in the carrying on of their own respective businesses or activities.

Any Shareholder and its officers, directors, shareholders, partners, members, agents and employees, and each director of TSN Canada Holdings or TSN Canada nominated by such Shareholder (collectively, a “Corporate Opportunities Group”) may investigate, engage in and/or possess any interest in other business ventures of every nature and description, independently or with others, whether existing as of the date hereof or hereafter coming into existence, without any accountability

to any other Party by virtue of this Agreement or under applicable law, and shall not be obligated to present any business opportunity to TSN Canada Holdings or TSN Canada or any other Shareholder or such other Shareholder’s Corporate Opportunities Group, even if the opportunity is of the character that, if presented to TSN Canada Holdings or TSN Canada, could be taken by one or both of them or, if presented to any other Shareholder or such other Shareholder’s Corporate Opportunities Group, could be taken by such Persons. Each Shareholder and its Corporate Opportunities Group shall have the right to hold any such business opportunity for its own account or to recommend such opportunity to Persons other than TSN Canada Holdings, TSN Canada, any other Shareholder or any Person in such other Shareholder’s Corporate Opportunities Group. No Party shall initiate, continue, maintain or support any action, claim, application, complaint or proceeding against any past or present member of a Corporate Opportunities Group arising from any alleged failure to bring a business opportunity to the attention of TSN Canada, TSN Canada Holdings or any Affiliate of either of them, or the failure to facilitate the exploitation of such business opportunity by any of them or alleging any breach of duty or oppression based on any activity permitted under this Section 11.2, and no Party shall cause, encourage or assist TSN Canada, TSN Canada Holdings or any other Person to do so. The obligations of a Party pursuant to the preceding sentence shall survive the termination or expiration of this Agreement, and shall continue regardless of whether the Party is a Shareholder or not. For greater certainty, a past or present member of a Corporate Opportunities Group shall be permitted to defend any such action, claim, application, complaint or proceeding by reference to this Section 11.2 which shall constitute a complete answer and defence to any such action, claim, application or proceeding.

11.3

and prior to any such action being taken, the Parties shall give due consideration to any changes which may be required to this Agreement in order to give effect to the intent of this Section.

11.4

Compliance with Restrictions

If TSN Canada Holdings or TSN Canada is advised by Industry Canada or the CRTC that it does not comply with the Restrictions, or if any action contemplated or proposed to be taken under this Agreement at the time would result in non-compliance with the Canadian Communications Statutes, the Shareholders will negotiate in good faith changes to its structure or governance to ensure that compliance with such Restrictions and the Canadian Communications Statutes is achieved, provided that no Shareholder shall be required to take any action or do any thing that, in its reasonable judgement, impairs or is likely to impair its, or any Affiliate’s, economic interest or liquidity in TSN Canada Holdings, TSN Canada and TSN US.
