Forward Looking Statements

2

This presentation contains “forward-looking statements” and “forward-looking information” within the meaning of the US Securities Act, as amended, the US Exchange Act, as amended, and the United States Private Securities Litigation Reform Act of 1995 with the intention of obtaining the benefits of the “safe harbour” provisions of such laws and applicable Canadian securities Laws concerning the proposed transaction and the business, operations and financial performance and condition of Goldcorp Inc. (“Goldcorp”) and Osisko Mining Corporation (collectively, the “Combined Company”) and estimated production and mine life of the various mineral projects of Goldcorp and Osisko.

Forward-looking statements include, but are not limited to, statements with respect to the future price of gold, silver, copper, lead and zinc, the estimation of mineral reserves and mineral resources, the realization of mineral reserve estimates, the timing and amount of estimated future production, costs of production, capital expenditures, costs and timing of the development of new deposits, success of exploration activities, permitting time lines, hedging practices, currency exchange rate fluctuations, requirements for additional capital, government regulation of mining operations, environmental risks, unanticipated reclamation expenses, timing and possible outcome of pending litigation, title disputes or claims, limitations on insurance coverage, expectations as to the anticipated timing, mechanics, completion and settlement of the Offer (as defined herein), the market for and listing of the common shares of Goldcorp, the value of the common shares of Goldcorp received as consideration under the Offer, the ability of Goldcorp to complete the transactions contemplated by the Offer, reasons to accept the Offer, the purpose of the Offer. Generally, these forward-looking statements can be identified by the use of forward-looking terminology such as “plans”, “expects”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, or “believes”, or the negative of these terms or other variations of these terms or variations of such words and phrases or state that certain actions, events or results “may”, “could”, “would”, “should”, “might”, “seeks” or “will”, “occur” or “be achieved” or the negative of these terms or other variations of these terms or comparable language, or by discussion of strategy or intentions.

Forward-looking statements are made based upon certain assumptions and other important factors that could cause Goldcorp’s actual results, performance or achievements to be materially different from future results, performances or achievements expressed or implied by such statements. Such statements and information are based on numerous assumptions regarding present and future business strategies and the environment in which Goldcorp will operate in the future, including that Goldcorp will be successful in acquiring 100% of the issued and outstanding common shares of Osisko, that all required third party regulatory and governmental approvals to the transaction will be obtained and all other conditions to completion of the transaction will be satisfied or waived, the price of gold and silver, anticipated costs and the ability to achieve goals. Many of these assumptions are based on factors and events that are not within the control of Goldcorp and there is no assurance they will prove to be correct. Certain important factors that could cause actual results, performances or achievements to differ materially from those in the forward-looking statements include, among others, gold price volatility, discrepancies between actual and estimated production, mineral reserves and resources and metallurgical recoveries, mining operational and development risks, litigation risks, regulatory restrictions (including environmental regulatory restrictions and liability), activities by governmental authorities (including changes in taxation), currency fluctuations, the speculative nature of gold exploration, the global economic climate, dilution, share price volatility, competition, loss of key employees, additional funding requirements and defective title to mineral claims or property. Although Goldcorp believes its expectations are based upon reasonable assumptions and has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended.

Forward-looking statements are subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of Goldcorp or Osisko to be materially different from those expressed or implied by such forward-looking statements, including but not limited to: future prices of gold, silver, copper, lead and zinc; risks related to the integration of acquisitions; risks related to international operations, including economic and political instability in foreign jurisdictions in which Goldcorp and Osisko operate; risks related to current global financial conditions; risks related to joint venture operations; actual results of current exploration activities; environmental risks; possible variations in ore reserves, grade or recovery rates; mine development and operating risks; accidents, labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing or in the completion of development or construction activities; risks related to indebtedness and the service of such indebtedness, the common shares of Goldcorp to be issued in connection with the Offer having a market value lower than expected, the businesses of Goldcorp and Osisko not being integrated successfully or such integration may be more difficult, time-consuming and more costly than expected and the expected combined benefit from the Offer not being fully realized or realized within the expected time frame, as well as those factors discussed in “Reasons to Accept the Offer” in Section 4 of the take-over bid circular to be dated on or about January 14, 2014 (the “Circular”), “Purpose of the Offer” in Section 5 of the Circular, “Plans for Osisko” in Section 6 of the Circular and “Acquisition Risks” in Section 7 of the Circular as well as those risk factors discussed or referred to in the section entitled “Risk Factors” in each of Goldcorp’s annual information form for the year ended December 31, 2012 and Osisko’s annual information form for the year ended December 31, 2012 and other reports filed with the applicable securities regulatory authorities in Canada and available under Goldcorp’s or Osisko’s profile at www.sedar.com, respectively.

The foregoing factors are not intended to represent a complete list of the factors that could affect Goldcorp and the acquisition of Osisko by Goldcorp. Additional factors are noted elsewhere in the Offer and Circular and in the documents incorporated by reference therein.

Although Goldcorp has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.

Forward-looking statements contained in this presentation are as of the date hereof or as otherwise indicated and, accordingly, are subject to change after such date. Except as otherwise indicated by Goldcorp, these statements do not reflect the potential impact of any non-recurring or other special items or of any dispositions, monetizations, mergers, acquisitions, other business combinations or other transactions that may be announced or that may occur after [the date hereof]. Forward-looking statements are provided for the purpose of providing information about management’s current expectations and plans and allowing investors and others to get a better understanding of Goldcorp’s operating environment. Goldcorp does not intend or undertake to publically update any forward-looking statements, whether as a result of new information, future events or otherwise, except in accordance with applicable securities laws. Any forward-looking statements of facts related to Osisko discussed or disclosed herein are derived from Osisko’s publicly filed documents or records.

This presentation does not constitute an offer to buy or an invitation to sell, or the solicitation of an offer to buy or invitation to sell, any securities of Goldcorp or Osisko. Such an offer may only be made pursuant to an offer and take-over bid circular Goldcorp intends to file with the Canadian securities regulators and pursuant to registration or qualification under the securities laws of any other such jurisdiction.

In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource estimates disclosed herein have been prepared in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”), classified in accordance with Canadian Institute of Mining Metallurgy and Petroleum’s “CIM Standards on Mineral Resources and Reserves Definitions and Guidelines” (the “CIM Guidelines”). The terms “mineral resources”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” are recognized by Canadian securities regulatory authorities, however, they are not defined under U.S. SEC Industry Guide 7 and are not recognized by the Securities and Exchange Commission and may not be recognized by the securities regulatory authorities of other jurisdictions. Pursuant to the CIM Guidelines, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as their economic and legal feasibility. Inferred mineral resources, when compared with measured or indicated mineral resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an inferred mineral resource will be upgraded to an indicated or measured mineral resource as a result of continued exploration. Pursuant to NI 43-101, inferred mineral resources may not form the basis of any economic analysis, including any feasibility study. Accordingly, readers are cautioned not to assume that all or any part of a mineral resource exists, will ever be converted into a mineral reserve, or is or will ever be economically or legally mineable or recovered.

All amounts are in U.S. dollars, unless otherwise stated.

Note 1: Total proven and probable mineral reserves are as at January 1, 2013 and are estimated at 310.6 million tonnes at 1.01 g Au/t for 10.1 million ounces. Source: Osisko news release dated February 19, 2013 “Osisko Updates Reserves at Canadian Malartic”, available under Osisko’s profile at www.sedar.com

Note 2: Free and adjusted operating cash flow, net asset value, and gold production and reserves are non-GAAP performance measures which Goldcorp believes that, in addition to conventional measures prepared in accordance with GAAP, Goldcorp and certain investors use to evaluate Goldcorp's ability to generate cash flows, its operating and economic performance and to provide measures which management uses internally to assess and evaluate the overall performance of its business and those of acquisition candidates and to highlight trends in the overall business. Accordingly, the measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. Free cash flows are calculated by deducting from net cash provided by operating activities, Goldcorp's share of expenditures on mining interests, deposits on mining interest expenditures and capitalized interest paid, and adding Goldcorp's share of free cash flows provided by operating activities from Alumbrera and Pueblo Viejo. Adjusted operating cash flows comprises Goldcorp’s share of operating cash flows before working capital changes, dividends from associates and adjusted operating cash flows provided by Alumbrera and Pueblo Viejo. Net asset value is estimated as the discounted future after-tax cash flows expected to be derived from a mine site, less an amount for costs to sell estimated based on similar past transactions. When discounting estimated future after-tax cash flows, the Company uses its after-tax weighted average costs of capital. Estimated cash flows are based on expected future production, metal selling prices, operating costs and non-expansionary capital expenditures, excluding those cash flows arising from future enhancements of the asset.

Note 3: The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” defined in accordance with NI 43-101 differ from the definitions in US SEC Industry Guide 7 (“SEC Industry Guide 7”) under the US Securities Act. Under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into reserves.
