On February 21, 2012, Mylan Pharmaceuticals Inc. (“MPI”), a wholly-owned subsidiary of Mylan Inc. (the “Company”), entered into a $300,000,000 accounts receivable securitization facility pursuant to (i) a Purchase and Contribution Agreement, between MPI and Mylan Securitization LLC, a wholly-owned special purpose subsidiary of MPI (the “SPV”), and (ii) a Receivables Purchase Agreement, among the SPV, as seller, MPI, as originator and servicer, certain conduit purchasers, committed purchasers and letter of credit issuers from time to time party thereto (collectively, the “Purchasers”), certain purchaser agents from time to time party thereto and The Bank of Tokyo-Mitsubishi UFJ, Ltd., New York Branch, as agent (the “Agent”). The Company agreed to enter into a performance guarantee with respect to the obligations of MPI under these agreements.

Under the Purchase and Contribution Agreement, MPI will sell, on an ongoing basis, certain accounts receivable, certain related assets and the right to the collections on those accounts receivable to the SPV. Once sold to the SPV, the accounts receivable, related assets and rights to collection described above will be separate and distinct from MPI’s own assets and will not be available to MPI’s creditors should MPI become insolvent. The servicing, administration and collection of the accounts receivable will be conducted by MPI, as servicer. Under the terms of the Receivables Purchase Agreement, the SPV may, from time to time, obtain up to $300,000,000 (in the form of cash or letters of credit for the benefit of MPI) from the Purchasers through the sale of its interest in such receivables, related assets and collections. The size of the accounts receivable securitization facility may be increased from time to time, upon request by the SPV and with the consent of the purchaser agents and the Agent, up to a maximum of $500,000,000. Purchases under the Receivables Purchase Agreement will be repaid as accounts receivable are collected, with new purchases being advanced as new accounts receivable are originated by MPI and sold to the SPV, with settlement occurring monthly. The SPV has the option to reduce the commitments under the Receivables Purchase Agreement. The SPV’s assets have been pledged to the Agent in support of its obligations under the Receivables Purchase Agreement. Any amounts outstanding under the facility will be recorded as a secured loan and the receivables underlying any borrowings will continue to be included in accounts receivable, net, in the Consolidated Balance Sheets of the Company. The accounts receivable securitization facility has a term of three years.

The Receivables Purchase Agreement contains various customary affirmative and negative covenants and also contains customary default and termination provisions, which provide for acceleration of amounts owed under the Receivables Purchase Agreement upon the occurrence of certain specified events, including, but not limited to, failure by the SPV to pay interest and other amounts due, defaults on certain indebtedness, certain judgments, change in control, certain events negatively affecting the overall credit quality of transferred accounts receivable, bankruptcy and insolvency events.

The information provided pursuant to Item 1.01 with respect to the Company’s guarantee of the obligations of MPI under Purchase and Contribution Agreement and Receivables Purchase Agreement is incorporated by reference into this Item 2.03.

On February 21, 2012, Mylan Inc., a Pennsylvania corporation (“Mylan” or the “Company”) is hosting an investor meeting in New York, during which it is providing its strategic vision for 2012 and beyond. As part of this, Mylan is presenting its financial guidance for 2012, reaffirming its growth targets for 2013, and outlining the key drivers for the Company’s continued long-term growth beyond 2013. The discussion topics will include those described below.

Mylan’s 2012 financial guidance includes adjusted diluted earnings per share of between $2.30 and $2.50, which would represent 18% growth over 2011 at the midpoint of the range. The Company’s guidance range for 2012 revenue is $6.8 billion to $7.2 billion, representing 14% annual growth at the midpoint of the range. Mylan is currently targeting adjusted diluted earnings per share of $6.00 in 2018, with opportunities already in house, including the initiatives described below.

Mylan anticipates that its growth will continue in 2012, driven by the anticipated launch of approximately 650 global products, including more than 100 in the U.S. with brand sales of more than $40 billion, according to IMS Health data. The Company intends to continue to broaden its geographic footprint and to expand its presence in India by launching a commercial business there during the first half of 2012.

The Company notes that other anticipated key drivers in 2012 include the continued growth of Mylan Specialty, led by its EpiPen^® Auto-Injector franchise, and the continued strong performance of its core generics business, particularly in the U.S.

Mylan expects adjusted EBITDA to be in the range of $1.75 billion to $1.95 billion. The guidance range with respect to adjusted operating cash flows is $900 million to $1.0 billion, with capital expenditures expected to be between $300 million and $400 million. These expenditures relate primarily to planned expansions including those with respect to the recently acquired injectable and respiratory platforms.

A full listing of the Company’s financial guidance for 2012, on an adjusted basis, along with the significant foreign currency exchange rates used in preparing the guidance, is detailed below:

Mylan reaffirms its target of $2.75 of adjusted diluted earnings per share in 2013, representing annual growth of 15% (from the midpoint of its 2012 range), and updates its 2013 revenue target to $7.5 billion.

Mylan anticipates more than $1.0 billion of revenue in 2013 from 2012 and 2013 new product launches. Additionally, the Company anticipates acceleration of its global Institutional business, continued growth in its Specialty business, and further geographic expansion of its Antiretroviral (ARV) business, all of which Mylan expects will help drive its 2013 performance. The Company also sees continued opportunities for margin expansion as it continues to reduce its costs and apply operational best practices across its organization.

Mylan will outline the following key drivers of its long-term growth in 2013 and beyond and state its commitment to achieving double-digit earnings growth beyond 2013.
