This press release 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 Corp. ("Osisko").

Forward-looking statements include, but are not limited to, statements with respect to the anticipated timing, mechanics, completion and settlement of the formal offer (the "Offer") to acquire all of the outstanding common shares of Osisko, 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. 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.

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 dated January 14, 2014 that has been filed under Osisko's profile on www.sedar.com and in the documents incorporated by reference therein.

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.
