                                              December 17, 2004




Dear Fellow Mylan Shareholder:

            We are strongly opposed to the proposed acquisition of King
Pharmaceuticals Inc. by Mylan Laboratories Inc. In this regard, it is important
to note that products responsible for nearly 66% of Kings net 2003 branded
product sale and royalties may face generic competition from patent expiration
and/or patent challenges in the next four years (see Attachment 1 to this letter
for details).

            In order to help us evaluate the Mylan/King situation, we retained
A.T. Kearney to provide us with a position paper on the pharmaceutical industry,
Mylan and the proposed Mylan/King transaction. The report, which runs over 40
pages, was prepared with the participation of 5 senior members of the A.T.
Kearney Pharmaceutical and Healthcare Practice. Among A.T. Kearney's conclusions
is the following:

            "Mylan has significant opportunities to improve the financial
      performance of both its generic and branded businesses and achieve revenue
      and EBITDA growth that is at least comparable to its peers. The King
      acquisition does not address the key strategic imperatives necessary to
      substantially improve Mylan's performance across both business segments.
      Given Mylan's need to improve its position in the generic market and
      unlock the value of Nebivolol, the King acquisition will not meet these
      needs and should be avoided."

            As an alternative to the transaction with King, on November 19,
2004, we sent a letter to Mylan proposing an acquisition of Mylan at $20 per
share. We indicated that we were prepared to enter into an acquisition contract
with Mylan without requiring a break-up fee. This would allow Mylan to seek
alternative buyers while we are doing customary due diligence. As we previously
advised the Board, we anticipate contributing, together with our affiliates,
$1.5 billion of the necessary equity. We are in discussions with a major
financial institution regarding additional funding, and based upon those
conversations, we are confident that once due diligence is provided, we would be
able to submit to the Board a fully funded transaction.

            On December 10, we reaffirmed our $20 per share acquisition
proposal. We also advised the Board that if they determine that Mylan cannot at
this time put Mylan up for sale or grant due diligence because of the current
King contract, we are willing to stand by our $20 per share proposal pending
either the determination of Mylan shareholders to vote the King transaction down
or the Board's determination that Mylan is legally free to put Mylan up for sale
and grant due diligence. Rather than contact us, Mylan has indicated that it
will not engage in discussions regarding our proposal. We continue to believe
that our proposal presents an excellent alternative for Mylan shareholders to
consider and we continue to stand by our $20 per share acquisition proposal.
HOWEVER, WHETHER OR NOT MYLAN SHAREHOLDERS DESIRE TO PURSUE OUR PROPOSAL, WE
BELIEVE THAT THE KING TRANSACTION SHOULD BE REJECTED BY MYLAN SHAREHOLDERS.

            We are not opposed to presenting Mylan shareholders with an
opportunity for a legitimate vote on the King transaction. However, given the
passage of time from the announcement of the proposed transaction we are very
concerned that the Mylan Board, acting with the advice of its legal and
financial advisors, may seek to avoid a shareholder vote by restructuring the
transaction with King. Mylan could seek to do this, for example, by changing the
transaction to include a lower component of Mylan stock and a cash payment by
Mylan. IF YOU FEEL AS WE DO THAT ANY MYLAN/KING COMBINATION SHOULD BE PUT TO A
VOTE OF MYLAN SHAREHOLDERS, PLEASE CONTACT OUR PROXY SOLICITORS, D.F. KING AT
800-269-6427 TO LET THEM KNOW OF YOUR CONCERNS.

            The Mylan Board has stated that "as fiduciaries" the Board seeks to
take actions in the best interest of Mylan's shareholders. We do not believe it
would ever be in the best interest of shareholders to complete a controversial
transaction like the King deal without submitting it to a shareholder vote. IF
MYLAN DOES DETERMINE TO ATTEMPT TO PROCEED WITH A TRANSACTION WITH KING WITHOUT
SEEKING MYLAN SHAREHOLDER APPROVAL, REST ASSURED THAT WE WILL RESIST IT AND THAT
WE WILL SEEK TO REPLACE THE MYLAN BOARD AS EARLY AS IS LEGALLY

PERMISSIBLE. WE WILL ALSO SEEK TO HOLD ALL OF MYLAN'S OFFICERS, DIRECTORS AND
ADVISORS WHO WERE INVOLVED IN SUCH ACTION FULLY RESPONSIBLE AND WILL CHALLENGE
ANY PURPORTED INDEMNITY PROTECTIONS UPON WHICH THEY MIGHT ATTEMPT TO RELY. WE
ALSO PROMISE, IF WE GAIN CONTROL, TO CONDUCT A THOROUGH REVIEW OF THE "BUSINESS
DEALS BETWEEN THE COMPANY AND OFFICERS, DIRECTORS OR THEIR RELATIVES" REFERRED
TO IN THE PITTSBURGH POST-GAZETTE ARTICLE QUOTED BELOW. MYLAN HAS ACCUSED US OF
ATTEMPTING TO INTIMIDATE THE MYLAN BOARD. WE ARE STATING PLAINLY THE ACTIONS WE
WILL TAKE IF MYLAN ATTEMPTS TO PROCEED WITH A KING TRANSACTION WITHOUT SEEKING
THE APPROVAL OF MYLAN SHAREHOLDERS. IF THIS IS INTIMIDATING TO THE MYLAN BOARD,
THEN SO BE IT.

            Like you, we have a vested interest in Mylan and we mean to protect
it. Although the Mylan Board continues to announce that they are acting "as
fiduciaries," given their favorable treatment of Mr. Coury in the face of
Mylan's performance relative to its largest competitors, and the questionable
corporate governance practices at Mylan, discussed below, why should we trust
them to do the right thing regarding the King transaction? As we have previously
stated, from time to time, we take short positions in securities that we believe
will fall in price. Mr. Coury has made much of the fact that we are short King
stock, and therefore stand to benefit if the price of King stock falls. However,
we point out to Mylan shareholders that while we are short only approximately
5.3 million shares of King, we own over 26 million shares of Mylan (an
investment of in excess of $450 million dollars). Our interests are aligned with
Mylan shareholders in protecting the value of Mylan. Contrast our position with
that of Mr. Coury who, while boasting that he is a wealthy man, has only seen
fit to purchase less than 2000 Mylan shares beyond those that were given to him
by the Company.

            The A.T. Kearney report referred to above, indicates that for fiscal
years 2002-2004, (years 2003 and 2004 being the "Coury years"), Mylan's revenue
and EBITDA grew at a compounded annual growth rate of 11.6 percent and 10.7
percent, respectively, compared to 21 and 28 percent for its largest
competitors. Given that performance, we would have expected Mr. Coury's
compensation to suffer. However, in the 2003 fiscal year, Mylan paid Mr. Coury
over $2.4 million in cash and stock options which Mylan reported as having a
potential realizable value of between $12.7 and $32.7 million. In the 2004
fiscal year, Mr. Coury was paid over $3 million in cash and received restricted
stock, which Mylan reported at a value of $6,150,375. We find this to be
offensive and, given the fact that Mylan's generic segment revenue decreased by
approximately 18 percent for the quarter ending September 30, 2004 over the
results for September 30, 2003, it appears to us that the Board's apparent
enthusiasm for existing management is misplaced.

            Corporate governance practices at Mylan have been subjected to
criticism, as reported in the interactive edition of the Pittsburgh Post-Gazette
on November 2, 2004:

                  GovernanceMetrics International, a New York firm that
            evaluates companies on corporate governance issues, ranks Mylan 2.5
            on a scale of 1 to 10, with 10 being the best. It faulted the drug
            maker for compensation practices, lack of independent directors, and
            business deals between the company and officers, directors or their
            relatives, said Gavin Anderson, GovernanceMetrics chief executive
            officer.

                  Anderson cited the $2 million bonus Coury received in the
            fiscal year ended March 31, $1.1 million of which was guaranteed.
            His firm considers seven of Mylan's 11 directors non-independent.
            Five are current or former officers.

                  In the face of mounting criticism, more companies are putting
            more outsiders on their boards, believing shareholder interests are
            better served if more directors have fewer ties with management.
            Charles Elson, chairman of the University of Delaware's Weinberg
            Center for Corporate Governance said independent directors control
            75 percent or more of the board seats at most companies.

                  Mylan has "an exceedingly high percentage of insiders or
            quasi-insiders compared to what's going on inside corporate America
            today," said Donald Hambrick, a management professor at Penn State's
            Smeal College of Business. "I can see why Icahn is trying to do what
            he is."

            As strong advocates for corporate democracy and shareholder rights
for many years, we are extremely angered by events regarding Mylan stock.
Recently, a New York based hedge fund, Perry Corp., made a filing with the
Securities and Exchange Commission reporting its ownership of nearly 10% of
Mylan's voting stock on a "hedged" basis. We are concerned that these hedging
transactions may interfere with shareholders' legitimate expectations regarding
"one person, one vote" and full enfranchisement for Mylan shareholders. We have
recently commenced a lawsuit in the United States District Court for the Middle
District of Pennsylvania to assure that voting of Mylan stock complies with
applicable law. Rather than join us in pursuing this matter, as we believe they
should, the Board of Mylan has instead indicated its intention to resist our
lawsuit, despite the Board's protestations that it acts "as fiduciaries" in the
best interests of Mylan's shareholders.

            MYLAN SHAREHOLDERS MUST BE ACTIVE AND VIGILANT IN PROTECTING THEIR
RIGHTS AND THEIR INTERESTS IN MYLAN. WE URGE YOU TO OPPOSE THE PROPOSED
MYLAN/KING TRANSACTION BY VOTING YOUR MYLAN SHARES AGAINST THE ISSUANCE OF MYLAN
STOCK IN THE PROPOSED TRANSACTION.



                                           Very truly yours,



                                           High River Limited Partnership

            King has a concentrated portfolio of brand name drugs consisting
mainly of five products: Altace(R); Skelaxin(R); Levoxyl(R); Thrombin(R) and
Sonata(R). As reflected in the King annual report on Form 10-K for the year
ended December 31, 2003 (the "King Annual Report") those products accounted for
approximately 77% of the net 2003 branded product sales and royalties ("2003
Brand Sales")(1). The King Annual Report states that, "if we cannot successfully
enforce our rights under the patents relating to three of our largest products,
Altace(R), Levoxyl(R) and Skelaxin(R), or relating to our product Prefest(R),
against generic drug manufacturers, our results of operations could be
materially adversely affected". Relevant drugs are discussed below:

      -     Altace(R) represents 38% of 2003 Brand Sales. Altace(R) may face
            generic competition as early as 2005 from the challenge of its
            patents by Cobalt Pharmaceutical, which filed with the FDA to obtain
            permission to market a generic version of Altace. In any event, the
            key Altace(R) patent expires in 2008.

      -     Levoxyl(R) represents 10% of 2003 Brand Sales. In June and July
            2004, the FDA approved applications by competitors to permit
            marketing of their products as equivalent to Levoxyl(R). King has
            stated that the FDA decision "will adversely affect net sales of
            Levoxyl(R), our results of operations and cash flows."

      -     Skelaxin(R) represents 13% of 2003 Brand Sales. Skelaxin(R) may face
            generic competition as early as 2005 from the challenge of its
            patents by several competitors which filed with the FDA to obtain
            permission to market a generic version of Skelaxin(R). King has
            stated that if King's petition to the FDA with respect to these
            matters is rejected, "there is a substantial likelihood that a
            generic version of Skelaxin(R) will enter the market and our
            business, financial condition, results of operations and cash flows
            could be materially adversely affected."

      -     Sonata(R) represents 5% of 2003 Brand Sales. The patent for
            Sonata(R) is expiring in June of 2008. As a result, King may face
            generic competition for Sonata(R) at that time.

----------
(1) 2003 Brand Sales constituted 90% of total King's sales for the period.

                                                                       EXHIBIT B

                  Mylan has "an exceedingly high percentage of insiders or
            quasi-insiders compared to what's going on inside corporate America
            today," said Donald Hambrick, a management professor at Penn State's
            Smeal College of Business. "I can see why Icahn is trying to do what
            he is."

            As strong advocates for corporate democracy and shareholder rights
for many years, we are extremely angered by events regarding Mylan stock.
Recently, a New York based hedge fund, Perry Corp., made a filing with the
Securities and Exchange Commission reporting its ownership of nearly 10% of
Mylan's voting stock on a "hedged" basis. We are concerned that these hedging
transactions may interfere with shareholders' legitimate expectations regarding
"one person, one vote" and full enfranchisement for Mylan shareholders. We have
recently commenced a lawsuit in the United States District Court for the Middle
District of Pennsylvania to assure that voting of Mylan stock complies with
applicable law. Rather than join us in pursuing this matter, as we believe they
should, the Board of Mylan has instead indicated its intention to resist our
lawsuit, despite the Board's protestations that it acts "as fiduciaries" in the
best interests of Mylan's shareholders.

            MYLAN SHAREHOLDERS MUST BE ACTIVE AND VIGILANT IN PROTECTING THEIR
RIGHTS AND THEIR INTERESTS IN MYLAN. WE URGE YOU TO OPPOSE THE PROPOSED
MYLAN/KING TRANSACTION BY VOTING YOUR MYLAN SHARES AGAINST THE ISSUANCE OF MYLAN
STOCK IN THE PROPOSED TRANSACTION.



                                               Very truly yours,



                                               High River Limited Partnership

            King has a concentrated portfolio of brand name drugs consisting
mainly of five products: Altace(R); Skelaxin(R); Levoxyl(R); Thrombin(R) and
Sonata(R). As reflected in the King annual report on Form 10-K for the year
ended December 31, 2003 (the "King Annual Report") those products accounted for
approximately 77% of the net 2003 branded product sales and royalties ("2003
Brand Sales")(2). The King Annual Report states that, "if we cannot successfully
enforce our rights under the patents relating to three of our largest products,
Altace(R), Levoxyl(R) and Skelaxin(R), or relating to our product Prefest(R),
against generic drug manufacturers, our results of operations could be
materially adversely affected". Relevant drugs are discussed below:

      -     Altace(R) represents 38% of 2003 Brand Sales. Altace(R) may face
            generic competition as early as 2005 from the challenge of its
            patents by Cobalt Pharmaceutical, which filed with the FDA to obtain
            permission to market a generic version of Altace. In any event, the
            key Altace(R) patent expires in 2008.

      -     Levoxyl(R) represents 10% of 2003 Brand Sales. In June and July
            2004, the FDA approved applications by competitors to permit
            marketing of their products as equivalent to Levoxyl(R). King has
            stated that the FDA decision "will adversely affect net sales of
            Levoxyl(R), our results of operations and cash flows."

      -     Skelaxin(R) represents 13% of 2003 Brand Sales. Skelaxin(R) may face
            generic competition as early as 2005 from the challenge of its
            patents by several competitors which filed with the FDA to obtain
            permission to market a generic version of Skelaxin(R). King has
            stated that if King's petition to the FDA with respect to these
            matters is rejected, "there is a substantial likelihood that a
            generic version of Skelaxin(R) will enter the market and our
            business, financial condition, results of operations and cash flows
            could be materially adversely affected."

      -     Sonata(R) represents 5% of 2003 Brand Sales. The patent for
            Sonata(R) is expiring in June of 2008. As a result, King may face
            generic competition for Sonata(R) at that time.


----------
(2) 2003 Brand Sales constituted 90% of total King's sales for the period.
