VIA FAX DELIVERY

Milan Puskar
Chairman of the Board
Mylan Laboratories, Inc.
1500 Corporate Drive
Suite 400
Canonsburg, Pennsylvania 15317-8574

Dear Mr. Puskar:

         We consider it to be very fortunate for Mylan  shareholders  that Mylan
did not go forward with its proposed acquisition of King Pharmaceuticals,  Inc.,
which we and other  Mylan  shareholders  criticized  from the  start.  Mylan was
willing to pay $16.66 per share of King stock.1  Yesterday  King stock closed at
$9.46.  Frankly,  it is hard for us to understand what could have lead the Mylan
Board to pursue the  proposed  King  transaction  in the first  place and we are
further  baffled  by your  failure  to engage us in  discussions  regarding  our
proposal to acquire Mylan.

         Six months ago we submitted a $20 per share  proposal to acquire  Mylan
with no "breakup  fee." We have  repeatedly  indicated  that we are available to
discuss that proposal with you. Even though the  performance of Mylan's  generic
segment  continues  to  deteriorate  (most  recently  earnings  from  operations
declined  16% in the fourth  quarter of fiscal year 2005  compared to the fourth
quarter of fiscal year 2004),  we continue to stand by our proposal.  On Mylan's
March 10, 2005  conference  call with  investors,  in reply to a question  posed
regarding  whether Mylan considered  itself as an "acquirer" or an "acquiree" in
the U.S. generic industry consolidation,  Mr. Coury responded that he "would not
rule out ... any  opportunities."  Shockingly,  even after making such statement
publicly,  Mylan has failed to engage in any  discussions  with us regarding our
proposal!  As we advised the Board in our prior  communications,  we  anticipate
contributing, together with our affiliates, $1.5 billion of the necessary equity
and we believe that after completing the customary due diligence,  we will be in
position to obtain any additional financing for the acquisition. We are prepared
to commence our diligence review immediately. We believe that Mylan's management
should let the shareholders  decide whether they desire to accept $20 per share.
It is  incumbent  on Mylan's  Board to pursue our  proposal  and not continue to
ignore  an  opportunity  to  provide  shareholders  with the  benefits  it would
provide.  We urge you to seize this  opportunity  for  shareholders  now,  as we
remain concerned that, under current  management,  Mylan will suffer  additional
deterioration in its business.

         We are also concerned that rather than seeking an open sale process for
Mylan, the Board may once again pursue an ill-advised  transaction that may have
a  negative  impact  on  Mylan's  business  and as a  result  make  Mylan a less
attractive  acquisition  candidate.  Our  sensitivity  in this  regard  has been
heightened by the  statement  made on February 24, 2005 by Mylan's legal counsel
that "the  reason  for the [2005  annual  shareholders]  meeting  being  held in
October was because of other events that the company  anticipates being involved
with in the summer ... ." Given  your near miss with the King  proposal,  we are
concerned about what other egregious errors Mylan may be on the verge of making.

         In that regard,  we are also watching  diligently to ensure  management
maximizes the benefits of nebivolol for Mylan  shareholders  in a timely fashion
and does not mishandle this unique opportunity. To date, Mylan has only provided
limited insight to investors regarding  nebivolol.  While we are excited for the
potential of nebivolol in hypertension,  the congestive heart failure market may
offer  the  greatest  opportunity  to Mylan.  We note that over the last  twelve
months  ended  March 31,  2005 the two  leading  brand name beta  blockers  with
indications for congestive heart failure are Toprol-XL  ($1,033MM in U.S. sales)
and Coreg  (517MM  GBP or $946MM in North  American  sales at  current  exchange
rates).  In a press  release  dated August 30, 2004,  Mylan CEO,  Robert  Coury,
stated "we would  like to extend  our  congratulations  to  Menarini  for having
completed a successful  heart failure study with  nebivolol.  These  preliminary
results provide  important  additional data and further  supports our excitement
regarding the potential health benefits nebivolol may hold". However,  Mylan has
not disclosed  whether it has  conducted  the  necessary  trials on nebivolol to
obtain  an  FDA  indication   for  congestive   heart  failure  or  to  properly
differentiate nebivolol for use in congestive heart failure from the other brand
name beta-blockers. The lack of communication regarding a drug of this potential
magnitude is, in our view, wrong and exacerbates our concerns  regarding Mylan's
plans  for  nebivolol.  We  expect  that  on June  14th,  the  date of the  next
investors'  presentation  scheduled  by Mylan,  Mylan  will  finally  clarify to
investors  both its plan for marketing  nebivolol and the progress (if any) made
to date in attempting to obtain an indication from the FDA for congestive  heart
failure.

         We  remind  you once  again  that  Mylan's  Board  should  be acting as
fiduciaries for all Mylan  shareholders.  You should not doubt that we will hold
Mylan Board members  personally  responsible and accountable for any failures to
properly discharge their duties.

                                Very truly yours,

                                High River Limited Partnership
