                    MYLAN LABORATORIES ANNOUNCES PRELIMINARY
                    FIRST QUARTER DILUTED EARNINGS PER SHARE

   - MYLAN EXTENDS SELF TENDER FROM 5:00 P.M. TO MIDNIGHT ON JULY 15, 2005 -

PITTSBURGH, PA - July 11, 2005 - Mylan Laboratories Inc. (NYSE: MYL) today
provided a preliminary range of first quarter fiscal 2006 adjusted diluted EPS
of between $0.24 and $0.26 and GAAP diluted EPS of between $0.14 and $0.16,
which includes $0.03 for a contingent liability with respect to
previously-disclosed lorazepam and clorazepate product litigation. Robert J.
Coury, Vice Chairman and Chief Executive Officer commented, "Even though these
results are preliminary, we are pleased with the ranges we are reporting, and
we look forward to our final results being released on July 19, 2005. The
purpose of providing preliminary first quarter EPS is to provide shareholders
with current information to allow them to consider their participation in our
"Dutch Auction" self-tender. We are also reaffirming guidance, including
adjusted diluted EPS, for fiscal 2006 and fiscal 2007, presented on June 14,
2005."

On June 16, 2005, the Company commenced a modified "Dutch Auction" self-tender
for up to approximately 48.8 million shares of its common stock (up to $1
billion). Today, the Company announced the extension of its self-tender from
5:00 p.m. to 12:00 midnight, New York City time, on Friday, July 15, 2005, in
accordance with regulations of the Securities and Exchange Commission.

Preliminary First Quarter Earnings

Based upon current information, the Company expects adjusted earnings per
diluted share to be between $0.24 and $0.26 and GAAP earnings per diluted share
to be between $0.14 and $0.16, in each case for the three month period ended
June 30, 2005. The above adjusted earnings per diluted share, which is a
non-GAAP measure, does not include: (1) certain ongoing research and
development and marketing costs related to nebivolol (the Company's
next-generation beta blocker) that will be incurred until an out-licensing
agreement relating to such product is signed, (2) costs, including
restructuring costs, related to Mylan Bertek, the subsidiary that Mylan
recently announced it was closing, and (3) a contingent legal liability related
to previously-disclosed litigation in connection with the Company's lorazepam
and clorazepate products. The Company continues to believe that it has
meritorious defenses with respect to the claims in the litigation and intends
to continue to vigorously defend its position, including pursuing a motion for
judgment as a matter of law or, in the alternative, a new trial, and if those
motions are denied, pursuing an appeal. A reconciliation of the preliminary
range of first quarter adjusted diluted EPS to GAAP diluted EPS is attached as
Appendix A to this press release.

The Company is currently in the process of compiling, analyzing and finalizing
the results for the first quarter and the Company's independent registered
public accounting firm has not yet completed its review of the first quarter
results. As such, there can be no assurance that the final adjusted or GAAP
earnings per diluted share will be within the ranges specified. Mylan expects
to report its final results for the first quarter of fiscal 2006 on July 19,
2005. Additional details regarding the conference call and webcast will be
provided via a separate press release.

Reaffirmation of Fiscal 2006 and Fiscal 2007 Guidance

Mylan also reaffirmed its fiscal 2006 and fiscal 2007 guidance previously
announced on June 14, 2005. For fiscal 2006, the Company reaffirmed adjusted
diluted EPS guidance of $0.92 to $1.15. For fiscal 2007, the Company reaffirmed
adjusted diluted EPS guidance of $1.20 to $1.74. A reconciliation of adjusted
diluted EPS guidance, which is a non-GAAP measure, to GAAP diluted EPS guidance
is attached as Appendix B to this press release.

Non-GAAP Financial Measures

Mylan has not previously disclosed non-GAAP financial measures when providing
historical financial results. However, due primarily to the closing of the
Company's Mylan Bertek subsidiary and the outlicensing of the Company's
nebivolol product (both of which were announced by Mylan on June 14, 2005),
Mylan now believes that an evaluation of its ongoing operations (and
comparisons of its current operations with future operations) would be
difficult if the disclosure of its financial results were limited to financial
measures prepared only in accordance with accounting principles generally
accepted in the United States (GAAP). In addition to disclosing its financial
results determined in accordance with GAAP, Mylan is disclosing non-GAAP
results that exclude special items such as those discussed above in order to
enhance investors' and other readers' understanding and assessment of the
Company's financial performance, because the Company's ongoing, normal business
operations do not include such special items. Also, management uses these
measures internally for forecasting and budgeting. Whenever Mylan uses such a
non-GAAP measure, it will provide a reconciliation of non-GAAP financial
measures to the most closely applicable GAAP financial measure. Investors and
other readers are encouraged to review the related GAAP financial measures and
the reconciliation of non-GAAP measures to their most closely applicable GAAP
measure set forth in Appendix A hereto and should consider non-GAAP measures
only as a supplement to, not as a substitute for or as a superior measure to,
measures of financial performance prepared in accordance with GAAP.

Self-Tender Extension

Mylan's modified "Dutch Auction" self-tender, which was originally due to
expire at 5:00 p.m., New York City time, on Friday, July 15, 2005, has been
extended seven hours and will now expire at 12:00 midnight, New York City time,
on Friday, July 15, 2005, unless Mylan further extends the self-tender. This
change was made in order to ensure that the information contained herein and in
an Amendment to Schedule TO being filed today is available to shareholders for
a sufficient period of time prior to the expiration of the self-tender, in
accordance with regulations of the Securities and Exchange Commission. All
terms and conditions of the Offer to Purchase and related material distributed
to shareholders, as amended on June 17, 2005 and July 11, 2005, continue to
apply to the self-tender, as extended.

Forward-Looking Statements

This press release includes statements that constitute "forward-looking
statements", including with regard to the Company's preliminary estimated first
quarter fiscal 2006 earnings per share range, the release of its final first
quarter results, the Company's fiscal 2006 and 2007 guidance and its pending
litigation. These statements are made pursuant to the safe harbor provisions of
the Private Securities Litigation Reform Act of 1995. Because such statements
inherently involve risks and uncertainties, actual future results may differ
materially from those expressed or implied by such forward-looking statements.
Factors that could cause or contribute to such differences include, but are not
limited to: the Company's ability to successfully develop, license or otherwise
acquire and introduce new products on a timely basis in relation to competing
product introductions; the Company's ability to obtain required FDA approvals
for new products on a timely basis; uncertainties regarding continued market
acceptance of and demand for the Company's products; the Company's periodic
dependence on a relatively small group of products as a significant source of
its net revenue or net income; unexpected delays in the Company's ability to
submit applications to the FDA; risks inherent in legal proceedings; the
effects of vigorous competition on commercial acceptance of the Company's
products and their pricing, including, without limitation, the impact of the
entry of generic competition for fentanyl; a regulatory or other delay
impacting the launch of nebivolol; the high cost and uncertainty associated
with compliance with extensive regulation of the pharmaceutical industry; the
possibility that the calculation and reporting of amounts owed in respect of
Medicaid and other governmental pricing programs could be challenged, and that
sanctions or penalties could be assessed; the significant research and
development expenditures the Company makes to develop products, the commercial
success of which is uncertain; the possible loss of business from the Company's
concentrated customer base; the potential costs and product introduction delays
that may result from use of legal, regulatory and legislative strategies by the
Company's competitors and other third parties, including the practice of
"authorized generics" and the use of citizen's petitions to delay or prevent
product introductions; the Company's dependence on third party suppliers and
distributors for raw materials; the possible negative effects of any
interruption of manufacturing of products at the Company's principal
facilities; the effects of consolidation of the Company's customer base;
uncertainties regarding patent, intellectual and other proprietary property
protections; the expending of substantial resources associated with litigation
involving patent or other intellectual property protection of products;
possible reductions in reimbursement rates for pharmaceutical products;
possible negative effects on product pricing of current or future legislative
or regulatory programs, including state Medicaid programs; uncertainties
regarding the Company's performance under indemnification clauses in certain
material agreements; inherent uncertainties involved in the estimates and
judgments used in the preparation of financial statements, and the providing of
estimates of financial measures, in accordance with GAAP and related standards;
prevailing market conditions; changes in economic and financial conditions of
the Company's business; uncertainties and matters beyond the control of
management, which could affect the Company's earnings guidance, as well as the
subjectivity inherent in any probability weighted analysis underlying the
Company's assumptions and estimates with respect to the future; and the fact
that the Company's books and records for the first quarter of fiscal 2006 have
not yet been finalized and the Company's independent auditors have not yet
reviewed such first quarter results. These cautionary statements should be
considered in connection with any subsequent written or oral forward-looking
statements that may be made by the Company or by persons acting on its behalf
and in conjunction with its periodic SEC filings. In addition, please refer to
the cautionary statements and risk factors in Item I of the Company's Form 10-K
for the year ended March 31, 2005, and in its other filings with the SEC. The
Company undertakes no obligation to update these statements for revisions or
changes after the date of this release.

Notwithstanding any statement in this press release to the contrary, the safe
harbor protections of the Private Securities Litigation Reform Act of 1995 do
not apply to statements made in connection with a tender offer.

   (1) Fiscal 2007 guidance excludes any potential impact for stock-based
compensation expenses upon adoption of SFAS No. 123(R), Share-Based Payment.
Management is currently assessing the impact that adoption of SFAS No. 123(R)
will have on the company's consolidated financial statements.

   (2) The adjustment relating to the contingent legal liability was not
included in the Reconciliation of Adjusted diluted EPS Guidance to GAAP diluted
EPS Guidance provided in a press release issued by Mylan on June 14, 2005.
However, in preparing its first quarter results, the Company determined that,
as a result of a June 1, 2005 jury verdict against the Company and one of its
subsidiaries in its previously-disclosed lorazepam and clorazepate product
litigation, a contingent liability of $12 million should be recorded. The GAAP
diluted EPS, as it appeared in such reconciliation table for fiscal 2006 in the
June 14, 2005 press release, was a low of $0.76 and a high of $0.99.
