G.   A  subsidiary  of  the  Company  was  involved  in a  dispute  with  KaiGai
     Pharmaceuticals,  Co.,  Ltd.  ("KaiGai")  relating  to a license and supply
     contract for nitroglycerin  transdermal  patches which both parties claimed
     was breached by the other.  KaiGai sought damages in excess of $20,000,000.
     The dispute was subject to binding arbitration,  and, in November 1999, the
     arbitration  panel denied  KaiGai's  request for  damages.  KaiGai filed an
     appeal in U.S.  District  Court and the  Company's  motion to  dismiss  the
     appeal was granted based upon untimely and improper  service of the appeal.
     KaiGai appealed the U.S. District Court's decision to the Court of Appeals.
     In January 2001, the appeal was dismissed and withdrawn.

     The Company had an  agreement  with  Genpharm  Inc.  ("Genpharm")  where it
     benefited  from the sale of  ranitidine  HCl tablets by  Novopharm  Limited
     ("Novopharm")  under a separate  agreement  between Genpharm and Novopharm.
     Based  on an  independent  audit,  Genpharm  initiated  a  lawsuit  against
     Novopharm to resolve contract  interpretation issues and collect additional
     funds due. In response to Genpharm's  suit,  Novopharm filed  counterclaims
     against  both  Genpharm  and the  Company in which  Novopharm  is  claiming
     damages  of up to  $60,000,000.  The  Company  believes  the  counterclaims
     against  Genpharm  and the Company are  without  merit and will  vigorously
     defend its position.

     In June 1998,  the  Company  filed suit in the Los Angeles  Superior  Court
     against  American  Bioscience,   Inc.  ("ABI"),   American   Pharmaceutical
     Partners,  Inc.  ("APP") and certain of their  directors and officers.  The
     Company's suit sought various legal and equitable remedies. The Los Angeles
     Superior Court issued a preliminary  injunction which,  among other things,
     prohibited the defendants from transferring or disposing of funds,  assets,
     technology or property without the Company's consent or commingling assets,
     property,  technology or personnel with those of another  company.  In June
     1999, the  defendants  filed an answer to and  cross-complaint  against the
     Company.  The cross-complaint  alleged violations of California state laws,
     interference with contractual relations and prospective economic advantage,
     fraud, slander, libel and other allegations.  The cross-complainants sought
     unspecified compensatory and punitive damages.

     In August 2000, the Company  entered into a settlement  agreement with ABI,
     APP and certain of their directors and officers. The settlement resulted in
     the  resolution  of all  differences,  disputes  and  claims  raised in the
     complaint and cross-complaint mentioned above. Upon settlement, the Company
     received

G.   (contd.)  $5,000,000  from ABI for its equity  investment in VivoRx Inc. In
     December 2000, as required under the terms of the  settlement,  the Company
     received  payment  from ABI for the  transfer to ABI of ABI's  common stock
     owned by the Company.  This payment has been included in other income,  net
     of expenses, in the amount of $9,200,000.

     In  December  1998,  the FTC  filed  suit in U.S.  District  Court  for the
     District of Columbia against the Company.  The FTC's complaint  alleges the
     Company   engaged  in   restraint  of  trade,   monopolization,   attempted
     monopolization   and  conspiracy  to  monopolize  arising  out  of  certain
     agreements  involving the supply of raw materials used to  manufacture  two
     drugs.

     The  FTC  also  sued in the  same  case  the  foreign  supplier  of the raw
     materials, the supplier's parent company and its United States distributor.
     Under the terms of the  agreements  related  to these  raw  materials,  the
     Company has agreed to indemnify  these  parties.  The Company is a party to
     other suits involving the Attorneys General from 33 states and more than 25
     putative  class  actions  that allege the same  conduct  alleged in the FTC
     suit, as well as alleged violations of state consumer protection laws.

     The relief  sought by the FTC  includes an  injunction  barring the Company
     from engaging in the challenged conduct, recision of certain agreements and
     disgorgement in excess of $120,000,000. The states and private parties seek
     similar relief,  treble damages and attorneys' fees. The Company's  motions
     to dismiss several of the private actions were granted.

     In July 2000,  the  Company  reached a  tentative  agreement  to settle the
     actions  brought by the FTC and the State Attorneys  General  regarding raw
     material contracts for lorazepam and clorazepate. The Company has agreed to
     pay $100,000,000,  plus up to $8,000,000 in attorneys' fees incurred by the
     States Attorneys General.  Based on the FTC commissioners'  approval of the
     Tentative  Settlement with the FTC and State Attorneys General, in December
     2000, the Company placed into escrow  $100,000,000.  Settlement papers have
     been  executed  and filed by the  parties,  and  final  court  approval  is
     pending.

     In July 2000,  the Company  also  reached a tentative  agreement  to settle
     private class action  lawsuits filed on behalf of consumers and third-party
     reimbursers related to the same facts and circumstances at issue in the FTC
     and States

G.   (contd.)Attorneys  General cases. The Company has agreed to pay $35,000,000
     to settle the third party  reimburser  actions,  plus up to  $4,000,000  in
     attorneys' fees incurred by counsel in the consumer actions.  The tentative
     settlement is subject to court approval.

     In total,  the Company has agreed to pay up to $147,000,000 to settle these
     actions  brought by the FTC, State Attorneys  General,  and certain private
     parties ("Tentative  Settlement").  The Tentative  Settlement also includes
     three  companies   indemnified  by  the  Company  -  Cambrex   Corporation,
     Profarmaco S.r.l. and Gyma Laboratories, Inc. Lawsuits not included in this
     Tentative Settlement  principally involve alleged direct purchasers such as
     wholesalers.

     A qui tam action was also commenced by a private party in the U.S. District
     Court  for the  District  of South  Carolina  purportedly  on behalf of the
     United  States  alleging  violations  of the  False  Claims  Act and  other
     statutes.  In January 2001, the District Court granted the Company's motion
     to dismiss. At this time, no notice of appeal has been filed.

     The Company believes that it has meritorious defenses,  with respect to the
     claims  asserted,  in  those  suits  which  are not  part of the  Tentative
     Settlement and will  vigorously  defend its position.  However,  an adverse
     result in these cases or, if the  Tentative  Settlement  is not approved by
     the court,  the  continued  litigation of those cases could have a material
     adverse  effect  on  the  Company's   financial  position  and  results  of
     operations.

ITEM 2. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Introduction

     Net earnings for the quarter ended  December 31, 2000,  were $37.6 million,
or $.30 per diluted share, compared to $40.4 million, or $.31 per diluted share,
for the same prior year  period.  Net loss for the nine month  period then ended

$147.0  million effect of the Tentative  Settlement  ($94.0 million net of tax),
net earnings for the nine months ended December 31, 2000,  would have been $89.1
million, or $.70 per diluted share.

In July 2000,  the Company  reached a tentative  settlement  with the FTC, State
Attorneys  General,  and certain private parties  ("Tentative  Settlement") with
regards to lawsuits filed against the Company relating to raw material contracts
on two of its products.

During the quarter  ended June 30, 2000,  the Company made a strategic  business
decision relating to the sales and marketing of its generic products. Within the
generic industry,  the buying patterns of certain classes of customers  resulted
in a  disproportionate  amount of their  purchases to occur late in the quarter.
The Company  indirectly  supported this practice  through discount and incentive
programs.   The  Company   decided  to  no  longer  support  this  practice  and
discontinued its related  incentive  programs.  While generic volume of products
shipped for the three months ended June 30, 2000, was adversely impacted by this
decision, subsequent quarters have approached more normal levels.

Results of Operations

Net Sales and Gross Profit

     Consolidated  net sales for the three months ended December 31, 2000,  were
$223.2  million  compared to $203.9  million for the same prior year  period,  a
$19.3 million or 9% increase.

Generic  net sales for the  current  three  month  period  were  $181.9  million
compared to $168.2 million for the same prior year period, a $13.7 million or 8%
increase.  New products launched subsequent to December 31, 1999,  increased net
sales for the current  three month period by $57.2  million,  with $42.0 million
resulting from  nifedipine,  over the same prior year period.  This increase was
offset by decreased  net sales of $32.5  million for  products  where prices had
been increased in prior years,  primarily  clorazepate and lorazepam,  and other
products of $9.9 million.  Generic  volume  decreased to 2.214 billion doses for
the current  three month period from 2.377 billion doses for the same prior year
period, a 7% decrease.

Brand net sales for the current three month period were $41.3  million  compared
to $35.7 million for the same prior year period, a $5.6 million or 16% increase.
The increase  from the prior year period is primarily  attributable  to sales of
new products,  Clozapine(R) and Digitek(R),  marketed by Bertek  Pharmaceuticals
Inc. ("Bertek") subsequent to December 31, 1999.

Consolidated  net sales for the nine months ended December 31, 2000, were $598.0
million  compared  to $575.5  million  for the same prior year  period,  a $22.5
million or 4% increase.

                    MYLAN LABORATORIES INC. AND SUBSIDIARIES

Generic net sales for the current nine month period were $493.9 million compared
to $484.0 million for the same prior year period, a $9.9 million or 2% increase.
New products launched  subsequent to December 31, 1999,  increased net sales for
the current  nine month  period by $154.3  million,  with $110.9  million of the
increase  from  nifedipine,  over the same prior year period.  This increase was
offset by decreased  net sales of $85.1  million for  products  where prices had
been increased in prior years,  primarily  clorazepate and lorazepam,  and other
products of $53.6 million.  Generic volume for the current nine month period was
6.078  billion  doses  compared to 6.437  billion  doses for the same prior year
period, a 6% decrease.  The decrease in generic volume primarily  related to the
change in sales and marketing strategy implemented in the quarter ended June 30,
2000.

Brand net sales for the current nine month period were $104.1  million  compared
to  $91.5  million  for the same  prior  year  period,  a $12.6  million  or 14%
increase.  New  products  marketed by Bertek  subsequent  to December  31, 1999,
Clozapine(R)  and  Digitek(R),  increased  net sales for the current  nine month
period by $10.7 million over the same prior year period.

Consolidated  gross  profit for the three months  ended  December 31, 2000,  was
$105.1  million  or 47% of net sales  compared  to $111.2  million or 55% of net
sales for the same prior year  period.  For the nine months  ended  December 31,
2000,  gross  profit was $276.3  million or 46% of net sales  compared to $318.2
million or 55% of net sales for the same prior year period.

Generic gross profit for the current three month period was $77.4 million or 43%
of generic net sales  compared to $86.0  million or 51% of generic net sales for
the same prior year  period,  an $8.6 million or 10%  decrease.  For the current
nine month period, generic gross profit was $206.5 million or 42% of generic net
sales  compared to $254.4 million or 53% of generic net sales for the same prior
year period,  a $47.9  million or 19%  decrease.  In the current  three and nine
month periods,  gross profit  contributed by new product launches  subsequent to
December 31,  1999,  were offset by decreased  gross profit on  clorazepate  and
lorazepam,  products  where  prices had been  increased in prior years and other
core generics as compared to the same prior year periods.  Additionally,  due to
contractual obligations, net sales of nifedipine are at relatively lower margins
and,  consequently,  have  contributed to the lower overall generic gross profit
realized by the Generic Segment.

                    MYLAN LABORATORIES INC. AND SUBSIDIARIES

Brand gross profit for the current  three month period was $27.7  million or 67%
of brand net sales  compared to $25.2  million or 71% of brand net sales for the
same prior year  period,  a $2.6 million or 10%  increase.  For the current nine
month  period,  brand gross  profit was $69.8  million or 67% of brand net sales
compared  to $63.8  million  or 70% of brand net sales for the same  prior  year
period,  a $6.0 million or 9% increase.  Increases in gross profit for the three
and nine month  periods were  primarily  attributable  to new products  marketed
subsequent to December 31, 1999.

Research and Development

     Consolidated  research and development  expenses for the three months ended
December 31, 2000,  were $15.8  million  compared to $12.4  million for the same
prior year period, a $3.4 million  increase.  For the nine months ended December
31, 2000,  consolidated  research and  development  expenses  were $49.6 million
compared  to $35.7  million  for the same prior  year  period,  a $13.9  million
increase.

Generic  research and  development  for the current three month period was $12.0
million compared to $9.7 million for the same prior year period. For the current
nine month period,  generic  research and development was $38.6 million compared
to $28.8 million for the same prior year period. The increases are primarily due
to increased  studies and  increased  license  expense for  marketing  rights to
certain products in development.

Brand  research  and  development  for the current  three month  period was $3.8
million compared to $2.7 million for the same prior year period. For the current
nine month period,  brand research and development was $11.0 million compared to
$6.9 million for the same prior year period.  These  increases are primarily due
to increased studies expense associated with product line expansions.

The  Company is actively  pursuing  joint  development  projects in an effort to
broaden its scope of capabilities in bringing to market new innovative products.
Such  arrangements  generally  provide for payments by the Company only upon the
attainment of certain  milestones.  While such  arrangements  help to reduce the
Company's financial risk for unsuccessful projects, attainment of milestones may
result in fluctuations in quarterly research and development.

Selling and Administrative Expenses

     Consolidated selling and administrative expenses were $40.6 million for the
three months ended  December  31, 2000,  compared to $40.4  million for the same
prior year  period.  For the nine months ended  December 31, 2000,  consolidated
selling  and  administrative  expenses  were $117.9  million  compared to $117.4
million for the same prior year period.

Generic selling and  administrative  expenses for the current three month period
were $10.0  million,  relatively  unchanged  from the same prior year  period of
$10.8  million.  For  the  current  nine  month  period,   generic  selling  and
administrative  expenses  decreased  $4.7  million to $27.7  million  from $32.4
million for the same prior year period. This decrease is primarily attributed to
decreased promotional expenses.

Brand  selling and  administrative  expenses for the current  three month period
were $22.1 million compared to $16.6 million for the same prior year period. For
the current nine month period,  brand selling and  administrative  expenses were
$54.0  million  compared to $43.8  million for the same prior year  period.  The
increase  for the current  three month period  relates  primarily to the charges
related to the Zagam(R)  product license and employee  severance and termination
costs related to the  restructuring  of the Brand Segment.  Bertek decreased the
carrying  value  of  the  Zagam(R)  product  license  by  $3.6  million  due  to
difficulties related to product supply. Consequently,  the carrying value of the
Zagam(R)  product  license was $3.2  million at  December  31,  2000.  The Brand
Segment  recorded $1.0 million for employee  severance and termination  costs in
connection  with  the  consolidation  of  its  non-manufacturing  operations  in
Raleigh, North Carolina. For the current nine month period, the increase relates
primarily  to  Zagam(R)  charges  of  $4.6  million,   employee   severance  and
termination costs of $1.0 million and product sample expense of $2.8 million.

Other Income

     Other income for the three months ended December 31, 2000, was $8.9 million
compared  to $6.9  million  for the  same  prior  year  period,  a $2.0  million
increase.   Under  the  terms  of  the  August  2000  settlement  with  American
Bioscience,  Inc.  ("ABI"),  the Company  recognized $9.2 million in the current
three month  period for the  transfer to ABI of ABI's  common stock owned by the
Company (see note G to the consolidated financial statements).  This increase in
other  income  was  partially  offset  by a loss  recognized  on  the  Company's
investment  in a limited  partnership.  In  addition,  in the three month period
ended December 31, 1999, the Company  recorded a reduction of the carrying value
of nonoperating assets.

                    MYLAN LABORATORIES INC. AND SUBSIDIARIES

Other income for the nine months ended  December  31,  2000,  was $31.1  million
compared  to $9.6  million  for the same  prior  year  period,  a $21.5  million
increase. This increase is primarily attributed to increased earnings recognized
in the  Company's  investment  in a limited  partnership,  the ABI  proceeds and
increased interest income.

Somerset

     Equity in the  earnings of Somerset  was $1.3  million for the three months
ended  December 31, 2000,  compared to a loss of $1.5 million for the same prior
year  period.  Equity in the loss of Somerset  was $0.8 million and $2.6 million
for the nine months ended  December 31, 2000, and 1999. The increase in earnings
for the current  three month  period was  primarily  attributable  to  decreased
research and development and a settlement with the Internal Revenue Service.

Income Taxes

     The Company's effective tax rate of 36% remained relatively  unchanged from
the same prior year  periods  and is expected  to remain at  approximately  this
level throughout fiscal year 2001.

Other Factors

     The  Tentative  Settlement  contributed  primarily to the increase in total
current assets and total current liabilities.

The addition of nifedipine to the Company's product line during the current nine
month period  resulted in increased  finished  goods  inventories  and increased
trade accounts payable.

During the current nine month  period,  the Company  liquidated  portions of its
marketable  securities and investment in a limited partnership to fund the Stock
Repurchase Program and the Tentative Settlement.  Consequently, other assets and
marketable securities have decreased for the current nine month period.

During the three month  period ended June 30, 2000,  the Company  completed  the
Stock Repurchase  Program  authorized and announced by the Board of Directors in
April  1997.  The  Company  repurchased  4,855,100  shares of  common  stock for
approximately $91.5 million.

The Company has initiated the consolidation of its Brand Segment. In addition to
strengthening  the  management  team,  the Brand  Segment  is in the  process of
relocating certain functions from three current locations to one location in

                                15

                    MYLAN LABORATORIES INC. AND SUBSIDIARIES

Raleigh,  North Carolina.  In addition to the $1.0 million in employee severance
and termination costs recorded in the current three month period,  the remaining
costs associated with the  consolidation are expected to be recognized in fiscal
year 2002.

In  February  2001,   the  Food  and  Drug   Administration   approved   Biovail
Corporation's  ("Biovail")  Abbreviated New Drug Application for 30mg nifedipine
extended-release  tablets,  the generic equivalent of Pfizer Inc.'s Procardia(R)
XL, which the Company currently markets. The Company believes the approval to be
contrary to the statute,  case law and the FDA's own publicly announced position
concerning the 180-day exclusivity  provision of the statute. If Biovail chooses
to launch its product,  the Company  would expect to  experience  decreased  net
sales  and,  to a  lesser  degree,  decreased  gross  profits.  The  Company  is
evaluating  its  options  and will take such  steps as it deems  appropriate  to
protect its interests.

Accounting Standards

     In June 1998, the Financial  Accounting Standards Board issued Statement of
Financial Accounting  Standards No. 133, "Accounting for Derivative  Instruments
and Hedging Activities". The effective date of this standard has been delayed to
fiscal years beginning after June 15, 2000. The Company is currently  evaluating
the impact of this standard on its financial position and results of operations.

In December 1999, the Securities and Exchange Commission issued Staff Accounting
Bulletin No. 101 - Revenue Recognition in Financial  Statements ("SAB No. 101").
The  implementation  date of SAB No. 101 has been  delayed to the fourth  fiscal
quarter of fiscal years beginning after December 15, 1999. The Company  believes
the  adoption  of SAB No. 101 will not have a material  impact on its  financial
position or results of operations.

Liquidity, Capital Resources and Financial Condition

     Working  capital  decreased to $516.8  million at December  31, 2000,  from
$596.2  million  at March 31,  2000.  The  ratio of  current  assets to  current
liabilities  decreased to 2.9 to 1 at December 31, 2000,  from 7.8 to 1 at March
31, 2000.  Primary causes for the change in the Company's current ratio were the
Tentative Settlement and completion of the Stock Repurchase Program.

The  decrease  in working  capital was  primarily  attributed  to the  Tentative
Settlement  and its partial  funding,  along with net  fluctuations  in accounts
receivable,  inventories and income taxes. While the Tentative Settlement, along
with its partial funding, impacted working capital and cash provided from

                                16

                    MYLAN LABORATORIES INC. AND SUBSIDIARIES

operating activities,  the liquidation of certain investments in anticipation of
the  payment has  resulted  in the  increase  in cash  provided  from  investing
activities.  The cash used for the  completion of the Stock  Repurchase  Program
also reduced working capital.

In December  2000,  the Company  placed into escrow $100.0 million in accordance
with the terms related to the Tentative  Settlement.  The remaining balance will
be  funded  through  currently   available  funds.  The  entire  $147.0  million
settlement remains subject to final court approval.

The Company  believes  that it has  meritorious  defenses,  with  respect to the
claims asserted,  in those suits which are not part of the Tentative  Settlement
and will  vigorously  defend its position.  However,  an adverse result in these
cases  or,  if the  Tentative  Settlement  is not  approved  by the  court,  the
continued  litigation of those cases could have a material adverse effect on the
Company's financial position and results of operations.

During the three month  period ended June 30, 2000,  the Company  completed  the
Stock Repurchase  Program  authorized and announced by the Board of Directors in
April  1997.  The  Company  repurchased  4,855,100  shares of  common  stock for
approximately $91.5 million through the use of currently available funds.

The Company  continues to examine  opportunities  to expand its business through
product and company  acquisitions.  The Company's capital  resources,  financial
condition and results of operations could be materially  impacted if the Company
were to complete one or more of such acquisitions.

Forward-Looking Statements

     The statements set forth in this Report  concerning the manner in which the
Company  intends to conduct  its future  operations,  potential  trends that may
impact  future  results of  operations,  and its beliefs or  expectations  about
future operations are forward-looking  statements.  The Company may be unable to
realize its plans and objectives due to various  important  factors,  including,
but not limited to, an  acceleration  in the erosion of prices of the  Company's
generic  pharmaceutical  products,  the Company's inability to obtain timely FDA
approval  for its new generic or brand  products,  the failure of the  Company's
brand products to find acceptance in the marketplace,  continuing  litigiousness
by brand  manufacturers  designed  to delay the  introduction  of the  Company's
generic products,  the failure of the court to approve the Tentative Settlement,
the failure of the Company to favorably  litigate or resolve the remaining cases
that  17

                    MYLAN LABORATORIES INC. AND SUBSIDIARIES

are not a part of the  Tentative  Settlement,  and the factors  described  under
"Forward  Looking  Statements" in Item 7 of the Company's  Annual Report on Form
10-K for the year ended March 31, 2000.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The information required by Item 3 has been disclosed in Item 7A of the
Company's  Annual  Report on Form 10-K for the year ended March 31, 2000.  There
has been no material change in the disclosure  regarding market risk,  except as
described below.

The fair market value of the debt securities held by the Company at December 31,
2000, was $19.7  million,  of which $0.5 million had maturities of less than one
year (the market values of which are generally  less  sensitive to interest rate
fluctuations  than is the case  with  longer  term debt  instruments).  The fair
market value of equity  securities held by the Company at December 31, 2000, was
$41.9 million. Such investments collectively represent 3% of the Company's total
assets as of  December  31,  2000,  and 15% of the  aggregate  value of debt and
equity  securities  and cash and cash  equivalents  held by the  Company at such
date.  Assuming  an  instantaneous  10%  decrease  in the  market  value  of the
Company's  debt and equity  securities,  the change in the aggregate fair market
value of these securities would be $6.2 million.

                           PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

         Since the date of the  filing of the  Company's  Annual  Report on Form
10-K for the year ended March 31,  2000,  there have been no material  new legal
proceedings   involving  the  Company  or  any  material  developments  to  such
proceedings, except as described below.

A   subsidiary   of  the  Company  was   involved  in  a  dispute   with  KaiGai
Pharmaceuticals,  Co., Ltd. ("KaiGai") relating to a license and supply contract
for nitroglycerin transdermal patches which both parties claimed was breached by
the other.  KaiGai  sought  damages in excess of  $20,000,000.  The  dispute was
subject to binding  arbitration,  and, in November 1999, the  arbitration  panel
denied  KaiGai's  request for damages.  KaiGai filed an appeal in U.S.  District
Court and the  Company's  motion to dismiss  the appeal was  granted  based upon
untimely and improper service of the appeal. KaiGai appealed the U.S. District

                                 18

                    MYLAN LABORATORIES INC. AND SUBSIDIARIES

Court's  decision  to the Court of  Appeals.  In  January  2001,  the appeal was
dismissed and withdrawn.

In June 1998,  the Company filed suit in the Los Angeles  Superior Court against
American  Bioscience,  Inc.  ("ABI"),  American  Pharmaceutical  Partners,  Inc.
("APP") and certain of their  directors and officers.  The Company's suit sought
various legal and equitable  remedies.  The Los Angeles  Superior Court issued a
preliminary injunction which, among other things, prohibited the defendants from
transferring or disposing of funds,  assets,  technology or property without the
Company's consent or commingling assets, property,  technology or personnel with
those of another  company.  In June 1999, the defendants  filed an answer to and
cross-complaint  against the Company. The cross-complaint  alleged violations of
California state laws,  interference with contractual  relations and prospective
economic  advantage,   fraud,   slander,   libel  and  other  allegations.   The
cross-complainants sought unspecified compensatory and punitive damages.

In August 2000,  the Company  entered into a settlement  agreement with ABI, APP
and certain of their  directors and  officers.  The  settlement  resulted in the
resolution of all  differences,  disputes and claims raised in the complaint and
cross-complaint   mentioned  above.   Upon  settlement,   the  Company  received
$5,000,000  from ABI for its equity  investment in VivoRx Inc. In December 2000,
as required under the terms of the settlement, the Company received payment from
ABI for the transfer to ABI of ABI's  common  stock owned by the  Company.  This
payment has been  included in other  income,  net of expenses,  in the amount of
$9,200,000.

In December 1998, the FTC filed suit in U.S.  District Court for the District of
Columbia against the Company. The FTC's complaint alleges the Company engaged in
restraint of trade,  monopolization,  attempted monopolization and conspiracy to
monopolize  arising  out of  certain  agreements  involving  the  supply  of raw
materials used to manufacture two drugs.

The FTC also sued in the same case the foreign  supplier  of the raw  materials,
the supplier's parent company and its United States distributor. Under the terms
of the  agreements  related to these raw  materials,  the  Company has agreed to
indemnify  these  parties.  The Company is a party to other suits  involving the
Attorneys  General from 33 states and more than 25 putative  class  actions that
allege the same conduct  alleged in the FTC suit, as well as alleged  violations
of state consumer protection laws.

                            19

                    MYLAN LABORATORIES INC. AND SUBSIDIARIES

The relief  sought by the FTC  includes an  injunction  barring the Company from
engaging  in  the  challenged  conduct,   recision  of  certain  agreements  and
disgorgement  in excess of  $120,000,000.  The states and private  parties  seek
similar  relief,  treble damages and attorneys'  fees. The Company's  motions to
dismiss several of the private actions were granted.

In July 2000,  the Company  reached a tentative  agreement to settle the actions
brought  by the FTC and the  State  Attorneys  General  regarding  raw  material
contracts  for  lorazepam  and  clorazepate.  The  Company  has  agreed  to  pay
$100,000,000,  plus up to $8,000,000  in attorneys'  fees incurred by the States
Attorneys  General.  Based on the FTC  commissioners'  approval of the Tentative
Settlement  with the FTC and State  Attorneys  General,  in December  2000,  the
Company placed into escrow  $100,000,000.  Settlement  papers have been executed
and filed by the parties, and final court approval is pending.

In July 2000,  the Company also reached a tentative  agreement to settle private
class action lawsuits filed on behalf of consumers and  third-party  reimbursers
related  to the same  facts  and  circumstances  at issue in the FTC and  States
Attorneys General cases. The Company has agreed to pay $35,000,000 to settle the
third  party  reimburser  actions,  plus up to  $4,000,000  in  attorneys'  fees
incurred by counsel in the consumer actions. The tentative settlement is subject
to court approval.

In total,  the  Company  has agreed to pay up to  $147,000,000  to settle  these
actions brought by the FTC, State Attorneys General, and certain private parties
("Tentative Settlement"). The Tentative Settlement also includes three companies
indemnified by the Company - Cambrex  Corporation,  Profarmaco  S.r.l.  and Gyma
Laboratories,   Inc.   Lawsuits  not  included  in  this  Tentative   Settlement
principally involve alleged direct purchasers such as wholesalers.

A qui tam  action was also  commenced  by a private  party in the U.S.  District
Court for the  District of South  Carolina  purportedly  on behalf of the United
States  alleging  violations  of the False  Claims  Act and other  statutes.  In
January 2001,  the District  Court granted the Company's  motion to dismiss.  At
this time, no notice of appeal has been filed.

The Company  believes  that it has  meritorious  defenses,  with  respect to the
claims asserted,  in those suits which are not part of the Tentative  Settlement
and will  vigorously  defend its position.  However,  an adverse result in these
cases  or,  if the  Tentative  Settlement  is not  approved  by the  court,  the
continued litigation

of those cases could have a material  adverse effect on the Company's  financial
position and results of operations.

In addition to these  cases,  in January  1999, a class action suit was filed by
Frank Ieradi on behalf of himself and other similarly  situated  shareholders in
the U.S.  District Court of the Western District of Pennsylvania.  In this suit,
the plaintiff alleged  violations of federal  securities laws by the Company and
certain  of its  current  and  former  directors  and  officers  and  asked  for
compensatory  damages in an unspecified  amount.  In December 1999, the District
Court granted the Company's motion to dismiss the case. In August 2000, the U.S.
Court of Appeals for the Third  Circuit  affirmed  the  decision of the District
Court. No further appeal of this case has been taken.

The Company is involved in various other legal  proceedings  that are considered
normal to its business. While it is not feasible to predict the ultimate outcome
of such  proceedings,  it is the opinion of management that the outcome of these
suits  will not have a  material  adverse  effect on the  Company's  operations,
financial position, or liquidity.
