Mylan Laboratories Announces $1.25 Billion Share Buyback, Expected to Represent Nearly 25% of the Company's StockCOMPANY ALSO ANNOUNCES ADDITIONAL STRATEGIC INITIATIVES: - PLANS TO OUT-LICENSE NEBIVOLOL - - DOUBLES ANNUAL DIVIDEND - - PROVIDES 2 YEARS OF REVENUE AND ADJUSTED EPS GUIDANCE -

PITTSBURGH, June 14, 2005 /PRNewswire-FirstCall via COMTEX/ -- Mylan Laboratories Inc. (NYSE: MYL) today announced several key strategic initiatives, including a $1.25 billion share buyback, comprised of a modified "Dutch Auction" self- tender for up to approximately 48.8 million shares (up to $1 billion) and a $250 million follow-on share repurchase program in the open market or otherwise. These share repurchases will represent, upon completion, nearly 25% of the Company's outstanding shares. In addition, the Company announced today that is increasing its annual dividend by 100%, effective as of the first quarter ending June 30, 2005. Mylan also announced plans to out-license nebivolol, the highly anticipated next-generation beta blocker.

In addition to these actions, the Company today also announced adjusted diluted EPS guidance of $0.92 to $1.15 in fiscal 2006 and $1.20 to $1.74 in fiscal 2007. A presentation with more specific information concerning these announcements is being provided via a live investor conference call and webcast, which is being archived and is available on www.mylan.com until June 21, 2005.

Robert J. Coury, Mylan's Vice Chairman and Chief Executive Officer, commented: "These strategic announcements demonstrate Mylan's continued commitment to enhancing our leading position in the generic pharmaceutical industry, while optimizing value for our shareholders. We are extremely well positioned to capitalize on multiple new product and other opportunities, and we believe today's announcements will be accretive to our shareholders and position the Company for significantly enhanced potential EPS growth."

$1.25 Billion Share Buyback Program

Mylan announced today that on June 16, 2005 it will commence a modified "Dutch Auction" self-tender for up to approximately 48.8 million shares (up to $1 billion) of its common stock. In the tender offer, shareholders will have the opportunity to tender some or all of their shares at a price not less than $18.00 per share or more than $20.50 per share. Based on the number of shares tendered and the prices specified by the tendering shareholders, Mylan will determine the lowest per share price within the range that will enable it to buy up to approximately 48.8 million shares, or such lesser number of shares as are properly tendered. If more than approximately 48.8 million shares are properly tendered at or below the determined price per share, Mylan will purchase shares tendered by such shareholders, at the determined price per share, on a pro rata basis, as will be specified in the offer to purchase relating to the tender offer that will be distributed to shareholders. Shareholders whose shares are purchased in the tender offer will be paid the determined price per share, net in cash, without interest, promptly following the expiration of the tender offer period, as it may be extended. Additionally, in the event the final purchase price is less than the maximum price of $20.50 per share and more than approximately 48.8 million shares are tendered, Mylan intends to exercise its right to purchase up to an additional 2% of its outstanding common stock without extending the tender offer, so that the Company can repurchase up to $1 billion of its common stock. The tender offer will not be contingent upon any minimum number of shares being tendered. The tender offer will be subject to a number of other terms and conditions, including the financing condition described below, as will be specified in the offer to purchase. The offer to purchase shares will expire at 5:00 p.m., New York City time, on Friday, July 15, 2005, unless extended.

Subsequent to the completion of the Dutch Auction self-tender, Mylan plans to buy back up to an additional $250 million of its common stock from time to time on the open market or otherwise. Upon completion of the self-tender and the open market purchases, and depending on the actual purchase price, the Company expects to have repurchased a total of nearly 25% of Mylan's outstanding shares.

Mr. Coury further stated, "We believe that the Dutch auction self-tender and follow-on buyback properly creates the right balance between doing what is right for our business and delivering value to our shareholders. As it relates to our business, the sheer magnitude of this buyback will enhance the impact to earnings per share going forward of any and all new opportunities that we add to our existing base, such as any future successful Paragraph IV challenges. We also believe that the positive impact of the nebivolol opportunity, combined with the strength of our generics pipeline, will be magnified for our shareholders due to the significant reduction in our shares outstanding."

Mylan has obtained a commitment letter from Merrill Lynch Capital Corporation and Merrill Lynch, Pierce, Fenner & Smith Incorporated for $975 million in commitments, of which it is expected that $775 million will be used, along with cash on hand, to finance the tender offer and the follow-on repurchase program. Accordingly, the tender offer will be conditioned upon receipt of this financing pursuant to the terms and conditions contained in the commitment letter and on terms satisfactory to Mylan on or prior to the expiration date of the tender offer and other customary conditions. Merrill Lynch & Co. is also the Company's financial advisor and the dealer manager for the tender offer. The information agent is Morrow & Co. and the depositary is American Stock Transfer Company. The offer to repurchase, letter of transmittal and related documents will be mailed to shareholders of record and will also be made available for distribution to beneficial owners of Mylan common stock. The remaining $200 million of the commitment is a revolving credit facility that may be used for general corporate purposes.

Dividend

Mylan also announced today that it will double its annual dividend from $0.12 per share to $0.24 per share. This dividend increase is effective with the dividend to be paid for the first quarter of fiscal 2006. The increased quarterly dividend of $0.06 per share will be payable on July 15, 2005 to Mylan shareholders of record at the close of business on June 30, 2005.

"Our enhanced dividend policy going forward reflects our long-standing commitment to focus on total return to shareholders, by striking a strong balance between share appreciation and our dividend," commented Mr. Coury.

Nebivolol

Mylan announced that it has decided to out-license nebivolol and provided an overview of the clinical program and commercialization potential of this highly anticipated beta-blocker.

Mr. Coury further commented: "At this time, we believe out-licensing nebivolol is the best available option that will allow us to effectively launch this important product with minimal risk, while maximizing the potential opportunity for our shareholders. In addition, we believe that this approach will allow us to commercialize the product in a way that is both cash-efficient and non-dilutive."

The nebivolol NDA for a hypertension indication was submitted to the Food and Drug Administration ("FDA") in April 2004, and Mylan has now received an Approvable Letter from the FDA. Final approval of nebivolol is contingent upon successfully satisfying additional FDA requirements regarding certain aspects of pre-clinical data and finalization of the labeling. The pre- clinical data submitted in the NDA was based upon studies previously conducted by Janssen Pharmaceutica Belgium (currently JNJ Pharmaceuticals R&D Beerse), the company from which Mylan licensed the product. Currently Mylan is conducting a pre-clinical study designed to address the questions posed by the FDA. The Company believes that the data from the ongoing pre-clinical study will satisfactorily resolve the FDA's questions and is committed to working diligently with the FDA towards final approval.

Mylan also announced that it has signed a collaboration agreement with Menarini International Operations Luxemburg ("Menarini"), one of the largest privately-held European pharmaceutical companies and the company that markets nebivolol in Europe, that allows Mylan to use the Study of Effects of Nebivolol Intervention on Outcomes and Rehospitalization in Seniors with Heart Failure ("SENIORS") trial in support of a US submission for congestive heart failure indication ("CHF"). Mylan anticipates filing a CHF NDA using the SENIORS trial and supportive data to request a CHF indication.

Mylan Bertek

Mylan also announced today that it will be closing its Mylan Bertek subsidiary, and will transfer responsibility for selling Mylan Bertek's products to its Mylan Pharmaceuticals and UDL subsidiaries.

Mr. Coury further commented: "After careful evaluation, we have concluded that the existing Mylan Bertek business is not the type of brand platform that would enable us to fulfill our long stated vision and objective of becoming a more balanced specialty pharmaceutical company. We believe that closing Mylan Bertek will streamline our operations and result in significant cost savings."

Financial Guidance for Fiscal 2006 and Fiscal 2007

Mylan today also provided financial guidance for fiscal 2006 and fiscal 2007. For fiscal 2006, the Company is forecasting adjusted diluted EPS in the range of $0.92 to $1.15 per share, and net revenues in the range of $1,135 million to $1,340 million. The Company reported that these estimates only include a partial year benefit from the share repurchases and do not include certain ongoing research and development and marketing costs related to nebivolol that will be incurred until an out-licensing agreement is signed. It also excludes all Mylan Bertek costs, including costs related to the restructuring. For fiscal 2007, Mylan is projecting adjusted diluted EPS in the range of $1.20 to $1.74 per share and net revenues in the range of $1,250 million to $1,600 million. Over the longer term, Mylan is projecting a compounded annual growth rate in EPS of approximately 20% over the next five years. A reconciliation of adjusted diluted EPS guidance to GAAP diluted EPS guidance is attached as an appendix to this press release.

Edward Borkowski, Mylan's Chief Financial Officer, stated: "We view the current fiscal year as a restructuring and transitional year. It is important to note that the spread in both the fiscal 2006 and 2007 guidance reflects the potential upside from the opportunities Mylan has before it. The low end of our guidance assumes no Paragraph IV wins. The high end of our guidance assumes that we are successful in our litigation against the brand companies on all six of our fiscal 2006 and 2007 potential Paragraph IV challenges, but we will still have competition from an authorized generic at launch."

Mr. Coury concluded: "As we have said many times before, Mylan's Board and management team are committed to maximizing shareholder value and total return of shareholder equity. Today, we have announced a number of measures that we believe strike the balance between positioning Mylan for both short- and long- term success while delivering total return to shareholders through share appreciation and our dividend policy."

Other Matters

Mylan also reacted to the letter dated June 1, 2005, in which an entity controlled by Carl Icahn referred to its purported interest in acquiring the Company at $20 per share. The Company noted that this letter was simply a reiteration of a letter Mr. Icahn sent to the Company last November. At that time, Mylan's Board of Directors concluded that Mr. Icahn had not made a serious offer for the Company and that discussions with him were not in the best interests of the Company. In view of the passage of time, the Board considered Mr. Icahn's latest letter and reached the same determination that it reached last November.
