TORONTO  - Maple Group Acquisition Corporation ("Maple"), a corporation formed by five of the country's largest pension funds and four Canadian bank-owned investment dealers, today announced that it has submitted a proposal to the Board of Directors of TMX Group  Inc. ("TMX Group") (TSX: X) to acquire all of its issued and outstanding shares in a transaction valued at approximately $3.6 billion.

Maple's investors include: Alberta Investment Management Corporation, Caisse de dépôt et placement du Québec, Canada Pension Plan Investment Board, CIBC World Markets Inc., Fonds de solidarité des travailleurs du Québec (F.T.Q.), National Bank Financial Inc., Ontario Teachers' Pension Plan Board, Scotia Capital Inc. and TD Securities Inc. Upon completion of the transaction, existing shareholders of TMX Group would own approximately 40% of Maple's outstanding shares, the pension fund investors would own approximately 35% and the bank-owned investment dealers would own approximately 25%. No shareholder of Maple would own more than 10% of Maple's total shares outstanding, consistent with the existing regulatory framework.

Speaking on behalf of Maple's investors, Luc Bertrand, Vice-Chairman of National Bank Financial Group, said: "As like-minded investors, we believe there is an opportunity to create significant value by capitalizing on TMX's strengths to build a stronger integrated exchange and clearing group - and by doing so, to secure the future growth and ongoing integrity of the Canadian capital markets. We believe our offer constitutes a superior proposal under which shareholders would receive cash, plus the opportunity to continue to participate in the company's ongoing growth. We welcome the opportunity to work with TMX's board and management to capture the benefits of our proposal for the company and all of its stakeholders."

Maple believes its proposal will enable TMX Group to achieve the scale and efficiency it needs to be successful in an increasingly competitive marketplace, while continuing to develop its unique capacity for serving global resource companies, as well as Canada's vibrant venture, energy and derivatives markets.  The Maple transaction will preserve Canadian governance, decision-making and regulatory oversight, and will position the company to pursue strategic opportunities internationally.

A Superior Proposal

Under the terms of its proposal, Maple would acquire all of the issued and outstanding common shares of TMX Group for, at the election of each shareholder, $48 in cash per TMX share or one common share of Maple per TMX share, in each case subject to pro ration.  The maximum aggregate amount of cash payable is $2.5 billion and the maximum number of Maple shares issuable is 22.5 million.

On a fully prorated basis, each TMX Group share would be exchanged for $33.52 in cash plus 0.3016 of a Maple share. The transaction represents a 24% premium to the implied value of the LSE offer based on the closing price and the Bank of Canada noon exchange rate on May 12, 2011, and a 20% premium to the volume weighted average price of the TMX Group's shares for the preceding 20 trading days.

Maple intends to preserve TMX Group's current corporate governance structure. At least half of the directors will be independent, at least 25% of the directors will be residents of Quebec, at least 25% will have expertise in or be associated with the Canadian public venture market and there will be fair and meaningful representation of directors with expertise in derivatives.

Maple intends to maintain TMX Group's current management and staffing levels, and will fulfil the TMX Group's 2008 undertakings to the Autorité des marchés financiers including a commitment to keep its derivatives trading and clearing business in Montreal. In addition, Maple commits to invest in the continued growth of TMX Group's derivatives trading and clearing business. Moreover, the integrated exchange model provides a stronger institution to meet Canada's obligation to facilitate the clearing of OTC derivatives.

Maple's proposed business model is aimed at building on TMX Group's position as the marketplace where a majority of global mining, oil & gas, and public venture companies list and trade.  Maple believes this will make TMX Group more competitive and ensure that the market as a whole, and market participants individually, benefit from the transaction. The Maple transaction has the support of many of Canada's largest capital market participants, including pension fund investors managing over $450 billion in assets. Maple's investors also include investment dealers owned by four of the six largest Canadian banks which, in the aggregate, are significant customers of TMX Group, representing 39% of the total volume and 41% of the total value traded on the TSX during the month of April 2011.

Combination with Alpha Group and CDS

A compelling part of Maple's proposal is the proposed combination of TMX Group with Alpha Group and CDS to create an integrated trading and clearing exchange for equities, bonds, energy products and derivatives in both exchange-traded and over-the-counter (OTC) markets.  This proven and highly-valued business model, which currently exists at Deutsche Börse, Hong Kong Exchanges and Clearing and the Australian Securities Exchange, would dramatically broaden TMX Group's business activities, generate substantial growth opportunities, and create significant synergies (including cost rationalization) all for the benefit of TMX Group, its shareholders and Canada's standing as a global financial centre of excellence.

Certain Maple investors have a significant equity ownership interest in each of Alpha Group and CDS and have agreed to use commercially reasonable efforts to complete transactions pursuant to which Alpha Group and CDS will be combined with TMX Group.  Maple intends to pursue the combination of TMX Group with Alpha Group and CDS as soon as possible following the completion of the acquisition of TMX Group. Although Maple's proposal to acquire TMX Group is not conditional on the concurrent combination with Alpha Group and CDS, Maple intends to seek the required regulatory approvals, including Competition Act and securities regulatory approvals from the Autorité des marches financiers and the Alberta, British Columbia and Ontario Securities Commissions, for such combinations, and the acquisition of TMX Group by Maple will be conditional on receipt of such regulatory approvals.

Accretive Transaction

The cash portion of Maple's proposal will be funded through debt and equity commitments, such that outstanding debt would represent approximately 2.9x trailing twelve months cash EBITDA. With the benefit of the proposed capital structure, Maple believes the transaction will be significantly accretive to the TMX Group's earnings per share. Even without the significant benefits of the proposed follow-on combination with Alpha and CDS, the Maple transaction is expected to be approximately $0.50 accretive to the TMX Group's analyst consensus 2012 EPS estimate of $3.48. Maple plans to maintain TMX Group's current annual dividend of $1.60 per share ($0.40 paid quarterly).

Conditions

In addition to the regulatory approvals described above, the acquisition of TMX Group will be subject to customary conditions, including approval by a minimum of 66 2/3% of TMX Group shareholders. Neither the acquisition of TMX Group, nor the subsequent combination of Alpha or CDS, requires approval under the Investment Canada Act.
