Item 5.  Other Events

Adoption of Rights Plan

     On August 22, 1996 (the "Rights Dividend  Declaration  Date"), the Board of
Directors of Mylan Laboratories Inc. (the  "Corporation")  adopted a Shareholder
Rights Plan and declared that a dividend of one share purchase  right  ("Right")
be distributed on each  outstanding  share of Common Stock,  par value $0.50 per
share ("Common Stock"), to shareholders of record as of the close of business on
September 5, 1996 (the "Record Date"). Each Right entitles the registered holder
to  purchase  from the  Corporation  one  one-thousandth  of a share of Series A
Junior  Participating  Preferred  Stock,  par value $0.50 per share  ("Preferred
Stock"), or, in certain circumstances, shares of Common Stock, other securities,
and/or cash or other property, at a Purchase Price of $90 per share of Preferred
Stock (or,  when  applicable,  Common  Stock,  securities,  cash,  and/or  other
property),  subject to  adjustment.  The complete  terms and  conditions  of the
Rights  are set forth in a Rights  Agreement  dated as of August  22,  1996 (the
"Rights  Agreement") between the Corporation and American Stock Transfer & Trust
Company, as Rights Agent.

     All shares of Common  Stock  outstanding  on the Record  Date will  receive
Rights. In addition, all shares of Common Stock issued prior to the Distribution
Date will be issued with Rights.  All certificates for Common Stock issued after
the  Record  Date and  prior to the  Distribution  Date  will  contain  a legend
incorporating the Rights Agreement by reference.

     Initially,  the  Rights  will  attach to the  outstanding  shares of Common
Stock, and no separate Right  Certificates will be distributed.  The Rights will
detach from the outstanding shares

                                       2.





of Common Stock and separate Right  Certificates  will be issued when there is a
Distribution  Date.  Until  a  Distribution  Date  occurs,  the  Rights  will be
evidenced by the  certificate for the shares of Common Stock with a copy of this
Summary of Rights  attached  thereto,  the Rights will  transfer  with (and only
with) the shares of Common  Stock to which such  Rights  are  attached,  and the
transfer of any  certificate  for Common  Stock (with or without this Summary of
Rights  attached  thereto)  will also  constitute  the  transfer  of the  Rights
attached to the shares of Common Stock represented by such certificate.

     A  "Distribution  Date" will occur on (i) the tenth day  following a public
announcement  that a person has  become an  Acquiring  Person  (the date of such
public  announcement being the "Shares  Acquisition  Date"), or (ii) if earlier,
the tenth  business day (or such later date as may be determined by the Board of
Directors  prior  to such  time  as any  person  becomes  an  Acquiring  Person)
following the  commencement  or  announcement of a tender or exchange offer that
would result in a person or group of affiliated or associated  persons  becoming
the Beneficial Owner of 15% or more of the outstanding shares of Common Stock.

     An  "Acquiring  Person" is a person or group of  affiliated  or  associated
persons that Beneficially  Owns 15% or more of the outstanding  shares of Common
Stock but does not include (1) the Corporation,  its subsidiaries,  any employee
benefit  plan  of the  Corporation  or any of its  Subsidiaries,  or any  entity
holding  shares of Common Stock  pursuant to the terms of any such plan; (2) any
person  or  group  that  becomes  the  Beneficial  Owner  of 15% or  more of the
outstanding  shares of Common  Stock  solely as a result of the  acquisition  of
Common Stock by the Corporation, unless such person or group thereafter acquires
additional  shares of Common  Stock;  or (3) subject to certain  conditions  set
forth in the Rights Agreement, a person that otherwise

                                       3.





would have become an Acquiring Person as a result of an inadvertent  acquisition
of 15% or more of the outstanding shares of Common Stock.

     The Rights are not exercisable  until the Distribution Date and will expire
at the close of business on  September  5, 2006 (the "Final  Expiration  Date"),
unless the Final  Expiration  Date is  extended or unless the Rights are earlier
redeemed or exchanged by the Corporation, in each case, as described below.

     As  soon  as  practicable  after  the  Distribution  Date,  separate  Right
Certificates  will be mailed to the holders of record of Common  Stock as of the
Distribution Date, and, thereafter,  the Right Certificates alone will represent
the Rights.

     The Purchase  Price  payable upon  exercise of the Rights and the number of
shares of Preferred Stock (and the amount of other  securities  and/or property,
if any) issuable upon exercise of the Rights are subject to adjustment from time
to time to prevent  dilution in the event that (i) there is a stock dividend on,
or a subdivision,  combination,  or  reclassification of the Preferred Stock, or
(ii) the holders of Preferred Stock are granted certain  options,  warrants,  or
rights to subscribe  for or purchase  shares of Preferred  Stock (or  equivalent
Preferred  Stock) or securities  convertible into Preferred Stock (or securities
convertible  into equivalent  Preferred  Stock) at a price less than the current
market price of Preferred  Stock,  or (iii) any  evidences  of  indebtedness  or
assets  (other than regular  quarterly  cash  dividends or dividends  payable in
shares of Preferred  Stock) or any  subscription  rights or warrants (other than
rights,  options,  or  warrants  of the type  referred to in clause (ii) of this
paragraph) are distributed to the holders of Preferred Stock.

                                   4.





     Subject to certain  exceptions  as set forth in the  Rights  Agreement,  no
adjustment  in  the  Purchase  Price  will  be  required  until  the  cumulative
adjustments amount to 1% of the Purchase Price.

     The number of outstanding Rights and the number of one one-thousandths of a
share of Preferred  Stock  issuable upon exercise of each Right are also subject
to  adjustment  in the  event of a stock  split of the  Common  Stock or a stock
dividend  on the shares of Common  Stock  payable  in shares of Common  Stock or
subdivisions,  consolidations,  or  combinations  of the shares of Common  Stock
occurring, in any such case, prior to the Distribution Date.

     No  fractional  shares of Preferred  Stock (other than  fractions  that are
integral multiples of one  one-thousandths of a share of Preferred Stock, which,
at the election of the  Corporation,  may be evidenced by  depository  receipts)
will be issued  upon  exercise  of the  Rights,  but,  in lieu  thereof,  a cash
adjustment  will be paid to the  holder  of the  exercised  Rights  based on the
market price of the  Preferred  Stock on the last trading date prior to the date
of exercise.

     Shares of Preferred Stock  purchasable upon exercise of the Rights will not
be redeemable. The dividend,  liquidation, and voting rights, and non-redemption
features  of the  Preferred  Stock  are  designed  so that  the  value  of a one
one-thousandth  interest in a share of Preferred Stock purchasable upon exercise
of each Right should  approximate  the value of one share of Common Stock.  Each
whole  share  of  Preferred  Stock  will be  entitled  to  receive  a  quarterly
preferential  dividend  equal to the  greater of (a) $1.00 or (b) 1000 times the
dividend  declared with respect to each share of Common  Stock.  In the event of
liquidation, the holders of each whole share of Preferred Stock will be entitled
to  receive a  preferential  liquidation  payment  equal to the  greater  of (a)
$1000.00 or (b) 1000 times the payment made per share of Common

                                       5.





Stock. Each share of Preferred Stock will have 1000 votes,  voting together with
the shares of Common Stock. Finally, in the event of any merger,  consolidation,
or other  transaction  in which  shares of Common  Stock  are  exchanged  for or
changed into other stock or securities,  cash, and/or other property, each share
of Preferred  Stock will be entitled to receive  1000 times the amount  received
per share of Common  Stock.  These  rights  and  preferences  are  protected  by
customary anti-dilution provisions.

     Once a person has become an  Acquiring  Person,  all  Rights  that are,  or
(under  certain   circumstances   specified  in  the  Rights   Agreement)  were,
Beneficially Owned by an Acquiring Person will be null and void.

     In the event that any person becomes an Acquiring Person,  proper provision
shall be made so that each holder of a Right  (other than a Right that is or was
Beneficially Owned by an Acquiring Person that has become null and void pursuant
to the  terms of the  Rights  Agreement),  shall  thereafter  have the  right to
receive  upon  exercise of such Right that number of shares of Common Stock (or,
in certain circumstances,  Preferred Stock, or other securities, property and/or
cash) having a value equal to two times the then-current Purchase Price.

     In the event that, at any time after a person becomes an Acquiring  Person,
(i) the  Corporation is acquired in a merger or other business  combination,  or
(ii) 50% or more of the  assets  or  earning  power of the  Corporation  and its
Subsidiaries  (taken  as a  whole)  is sold  or  otherwise  transferred,  proper
provision  will be made so that each holder of a Right  (other than a Right that
is or was  Beneficially  Owned by an  Acquiring  Person that has become null and
void pursuant to the terms of the Rights  Agreement)  shall  thereafter have the
right to receive  upon  exercise of such Right,  in lieu of shares of  Preferred
Stock, shares of common stock of the

                                       6.





     acquiror  then  having  a  current  market  value  equal to two  times  the
then-current  Purchase Price. The events referred to in the preceding  paragraph
and in clauses (i) and (ii) of this  paragraph  are  hereinafter  referred to as
"Triggering Events."

     At any time  prior to the  Close of  Business  on the  tenth  calendar  day
following  the  Shares  Acquisition  Date (or,  if the Shares  Acquisition  Date
occurred  prior to the Record Date,  the Close of Business on the tenth calendar
day following such Record Date),  the Board of Directors of the  Corporation may
redeem  the  Rights in whole,  but not in part,  at a price of $0.001 per Right,
subject to adjustment (the "Redemption Price") provided,  however,  that if such
authorization  occurs on or after the date of a change  (resulting  from a proxy
solicitation)  in a majority of the directors in office at the  commencement  of
such  solicitation,  and  any  Person  who  is or  was  a  participant  in  such
solicitation  has stated (or if upon the  commencement of such  solicitation,  a
majority of the Board of Directors of the  Corporation  has  determined  in good
faith) that such Person (or any of its  Affiliates or  Associates)  has taken or
intends to take,  or may consider  taking,  any action that would result in such
Person  becoming an  Acquiring  Person or that would cause the  occurrence  of a
Triggering Event (the existence of the circumstances described in this provision
being referred to herein as an "Adverse Change of Control"), then the Rights may
be so  redeemed  only if there  are  Continuing  Directors  in  office  and such
redemption  is  authorized  by a  majority  of such  Continuing  Directors.  The
redemption of the Rights may be made effective at such time, on such basis,  and
with  such  conditions  as the Board of  Directors  in its sole  discretion  may
establish.  Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price.

                                       7.





     At any time after any person becomes an Acquiring Person,  and prior to the
time any  person  (other  than the  Corporation,  any of its  Subsidiaries,  any
employee  benefit plan of the  Corporation or any of its  Subsidiaries,  and any
entity  holding  shares of Common Stock  pursuant to the terms of any such plan)
becomes the Beneficial Owner of 50% or more of the outstanding  shares of Common
Stock,  the  Corporation  may,  at the  option  and  election  of the  Board  of
Directors, exchange shares of Common Stock (or in certain circumstances,  shares
of Preferred Stock) for all or any part of the  then-outstanding and unexercised
Rights  (other than Rights that are or were  Beneficially  Owned by an Acquiring
Person  that have  become  null and void  pursuant  to the  terms of the  Rights
Agreement)  at an  exchange  rate of one  share of Common  Stock (or in  certain
circumstances,  one  one-thousandth  of a share of  Preferred  Stock) per Right,
appropriately adjusted to reflect any stock dividend, stock split, reverse stock
split,  or  other  similar  transaction  occurring  after  the  Rights  Dividend
Declaration Date.

     The terms of the Rights may be  amended  by the Board of  Directors  of the
Corporation  without the consent of the holders of the Rights,  except that from
and after the Close of Business on the tenth  calendar day  following the Shares
Acquisition  Date (or,  if the Shares  Acquisition  Date  occurred  prior to the
Record  Date,  the Close of Business on the tenth  calendar day  following  such
Record Date) no such amendment may adversely affect the interests of the holders
of the Rights  (other  than  Rights  that are or were  Beneficially  Owned by an
Acquiring  Person that have  become  null and void  pursuant to the terms of the
Rights  Agreement) and provided,  however,  that if such amendment  occurs on or
after an Adverse Change of Control,  then the Rights Plan may be amended only if
there are  Continuing  Directors in office and such amendment is authorized by a
majority of such Continuing Directors.

                                       8.





     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a shareholder of the Corporation,  including,  without limitation, the
right to vote or to receive dividends.

                        RESOLUTION OF BOARD OF DIRECTORS
                       TO AMEND ARTICLES OF INCORPORATION
                   TO ESTABLISH A SERIES OF PREFERRED SHARES*


     RESOLVED, that pursuant to the authority granted to and vested in the Board
of Directors of the Company in accordance with the provisions of the Amended and
Restated  Articles of  Incorporation  of the  Company  and  Section  1522 of the
Pennsylvania Business Corporation Law, as amended, the Board of Directors hereby
adopts and  approves  an  amendment  to the  Amended  and  Restated  Articles of
Incorporation  of the Company,  as amended,  which creates out of the authorized
but  unissued  shares of  Preferred  Stock,  par value  $0.50 per share,  of the
Company a series of Preferred  Stock,  the designation and authorized  number of
shares of which, and the terms and relative rights,  preferences and limitations
of which, are as follows:

                  Section 1.  Designation and Amount.  The shares of such series
                  shall  be  designated   as  "Series  A  Junior   Participating
                  Preferred  Stock"  (the  "Series A  Preferred  Stock") and the
                  number of shares  constituting  the Series A  Preferred  Stock
                  shall be 300,000.  Such number of shares may be  increased  or
                  decreased by resolution  of the Board of Directors;  provided,
                  (a) that no  decrease  shall  reduce  the  number of shares of
                  Series A  Preferred  Stock to a number less than the number of
                  shares then outstanding plus the number of shares reserved for
                  issuance upon the exercise of outstanding options,  rights, or
                  warrants or upon the conversion of any outstanding  securities
                  issued by the corporation  convertible into Series A Preferred
                  Stock; and (b) no increase shall cause the aggregate number of
                  all  shares  of  Preferred   Stock  that  the  corporation  is
                  authorized  to issue to be greater than is authorized by these
                  Amended and Restated Articles of Incorporation.

                  Section 2. Dividends and Distributions.

                           (A)  Subject  to the  rights  of the  holders  of any
                  shares  of  any  other  series  of  Preferred   Stock  of  the
                  corporation  (or any similar stock) ranking prior and superior
                  to the Series A Preferred Stock with respect to dividends, the
                  holders of shares of Series A Preferred  Stock,  in preference
                  to the holders of Common Stock, par value $0.50 per share (the
                  "Common Stock"),  of the corporation,  and of any other junior
                  stock, shall be


                                       12.





                  entitled to receive,  when, as and if declared by the Board of
                  Directors  out of funds  legally  available  for the  purpose,
                  quarterly dividends payable in cash on the first day of March,
                  June,  September,  and  December  in each year (each such date
                  being  referred  to herein as a  "Quarterly  Dividend  Payment
                  Date"),  commencing on the first  Quarterly  Dividend  Payment
                  Date  after the first  issuance  of a share or  fraction  of a
                  share of Series A  Preferred  Stock,  in an  amount  per share
                  (rounded to the  nearest  cent) equal to the greater of (a) $1
                  or (b) subject to the provision for adjustment hereinafter set
                  forth,  1000 times the  aggregate per share amount of all cash
                  dividends,  and 1000  times the  aggregate  per  share  amount
                  (payable  in  kind)  of  all   non-cash   dividends  or  other
                  distributions,  other  than a  dividend  payable  in shares of
                  Common Stock or a  subdivision  of the  outstanding  shares of
                  Common Stock (by  reclassification or otherwise),  declared on
                  the Common  Stock since the  immediately  preceding  Quarterly
                  Dividend  Payment Date or, with respect to the first Quarterly
                  Dividend  Payment Date,  since the first issuance of any share
                  or  fraction of a share of Series A  Preferred  Stock.  In the
                  event the  corporation  shall at any time  declare  or pay any
                  dividend  on the  Common  Stock  payable  in  shares of Common
                  Stock, or effect a subdivision or combination or consolidation
                  of the outstanding shares of Common Stock (by reclassification
                  or otherwise than by payment of a dividend in shares of Common
                  Stock)  into a greater  or  lesser  number of shares of Common
                  Stock,  then in each such case the amount to which  holders of
                  shares of Series A Preferred  Stock were entitled  immediately
                  prior to such event under clause (b) of the preceding sentence
                  shall be adjusted by  multiplying  such amount by a frac tion,
                  the numerator of which is the number of shares of Common Stock
                  outstanding  immediately  after such event and the denominator
                  of which is the  number of shares  of Common  Stock  that were
                  outstanding immediately prior to such event.

                           (B) The  corporation  shall  declare  a  dividend  or
                  distribution  on the Series A  Preferred  Stock as provided in
                  paragraph (A) of this Section  immediately after it declares a
                  dividend or  distribution  on the Common  Stock  (other than a
                  dividend payable in shares of Common Stock); provided that, in
                  the event no

                                       13.





                  dividend  or  distribution  shall  have been  declared  on the
                  Common Stock during the period between any Quarterly  Dividend
                  Payment  Date  and  the  next  subsequent  Quarterly  Dividend
                  Payment  Date,  a  dividend  of $1 per  share on the  Series A
                  Preferred   Stock  shall   nevertheless  be  payable  on  such
                  subsequent Quarterly Dividend Payment Date.

                           (C) Dividends shall begin to accrue and be cumulative
                  on  outstanding  shares of Series A  Preferred  Stock from the
                  Quarterly  Dividend  Payment Date next  preceding  the date of
                  issue of such shares,  unless the date of issue of such shares
                  is prior to the record date for the first  Quarterly  Dividend
                  Payment  Date,  in which case  dividends  on such shares shall
                  begin to  accrue  from the  date of issue of such  shares,  or
                  unless the date of is sue is a Quarterly Dividend Payment Date
                  or is a date after the record  date for the  determination  of
                  holders  of shares of Series A  Preferred  Stock  entitled  to
                  receive  a  quarterly   dividend  and  before  such  Quarterly
                  Dividend   Payment  Date,  in  either  of  which  events  such
                  dividends  shall begin to accrue and be  cumulative  from such
                  Quarterly  Dividend Payment Date. Accrued but unpaid dividends
                  shall  not bear  interest.  Dividends  paid on the  shares  of
                  Series A  Preferred  Stock in an  amount  less  than the total
                  amount of such  dividends  at the time  accrued and payable on
                  such shares  shall be allocated  pro rata on a  share-by-share
                  basis among all such shares at the time outstanding. The Board
                  of Directors  may fix a record date for the  determination  of
                  holders  of shares of Series A  Preferred  Stock  entitled  to
                  receive  payment  of  a  dividend  or  distribution   declared
                  thereon,  which  record  date  shall be not more  than 60 days
                  prior to the date fixed for the payment thereof.

                  Section 3. Voting Rights.  The holders of shares of
                  Series A Preferred Stock shall have the following voting
                  rights:

                           (A)   Subject  to  the   provision   for   adjustment
                  hereinafter set forth,  each share of Series A Preferred Stock
                  shall entitle the holder  thereof to 1000 votes on all matters
                  submitted to a vote of the shareholders of the corporation. In
                  the event the corporation shall at any time declare or pay any
                  dividend on the Common Stock

                                       14.

                  combination  or  consolidation  of the  outstanding  shares of
                  Common Stock (by reclassification or otherwise than by payment
                  of a  dividend  in shares of Common  Stock)  into a greater or
                  lesser  number of shares  of Common  Stock,  then in each such
                  case the number of votes per share to which  holders of shares
                  of Series A Preferred Stock were entitled immediately prior to
                  such event shall be adjusted by  multiplying  such number by a
                  fraction,  the  numerator  of which is the number of shares of
                  Common Stock outstanding  immediately after such event and the
                  denominator  of which is the number of shares of Common  Stock
                  that were outstanding immediately prior to such event.

                           (B)  Except as  otherwise  provided  herein or in any
                  other  Statement with Respect to Shares or other  amendment of

                  on all  matters  submitted  to a vote of  shareholders  of the
                  corporation.

                           (C)  Except  as set  forth  herein,  or as  otherwise
                  provided  by law,  holders of Series A  Preferred  Stock shall
                  have no special  voting  rights and their consent shall not be
                  required  (except to the extent they are entitled to vote with
                  holders of Common  Stock as set forth  herein)  for taking any
                  corporate action.

                  arrears  in  proportion  to the  total  amounts  to which  the
                  holders of all such shares are then entitled;

                  of the  corporation  to  purchase  or  otherwise  acquire  for

                                       16.

                  after the  acquisition  thereof.  All such  shares  shall upon
                  their  cancellation  become  authorized but unissued shares of
                  Preferred Stock and may be reissued as part of a new series of
                  Preferred Stock subject to the conditions and  restrictions on
                  issuance set forth herein,  in the Articles of  Incorporation,

                  stock  ranking   junior   (either  as  to  dividends  or  upon
                  liquidation,  dissolution,  or  winding  up) to the  Series  A
                  Preferred  Stock  unless  the  holders  of  shares of Series A
                  Preferred  Stock  outstanding  shall have  received out of the
                  assets  of  the  Company  available  for  distribution  to its
                  shareholders  after  payment or  provision  for payment of any
                  securities ranking senior to the Series A Preferred Stock, for
                  each share of Series A Preferred Stock,  subject to adjustment
                  as hereinafter provided,  (A) $1000.00 plus an amount equal to
                  accrued  and  unpaid  dividends  and  distributions   thereon,
                  whether or not  declared,  to the date of such payment or, (B)
                  if greater than the amount  specified in clause (1)(A) of this
                  sentence,  an amount equal to 1000 times the aggregate  amount
                  to be distributed per share to holders of Common Stock, as the
                  same may be adjusted as herein provided, or (2) to the holders
                  of shares of stock ranking on a parity (either as to dividends
                  or upon  liquidation,  dissolution,  or  winding  up) with the
                  Series A  Preferred  Stock,  unless  simultaneously  therewith
                  distributions are made ratably on the Series A Preferred Stock
                  and all such parity stock in  proportion  to the total amounts
                  to which the holders of all such shares are entitled upon such
                  liquidation,  dissolution,  or  winding  up.  In the event the
                  corporation  shall at any time  declare or pay any dividend on
                  the Common Stock payable in shares of Common Stock,  or effect
                  a  subdivision  or  combination   or   consolidation   of  the
                  outstanding shares of Common

                                       17.





                  Stock (by  reclassification  or otherwise than by payment of a
                  dividend  in shares of Common  Stock) into a greater or lesser
                  number of shares of Common  Stock,  then in each such case the
                  aggregate  amount  to which  holders  of  shares  of  Series A
                  Preferred Stock were entitled  immediately prior to such event
                  under the  provision in clause (1) of the  preceding  sentence
                  shall be adjusted by multiplying such amount by a fraction the
                  numerator  of which is the  number of  shares of Common  Stock
                  outstanding  immediately  after such event and the denominator
                  of which is the  number of shares  of Common  Stock  that were
                  outstanding immediately prior to such event.

                  Section 7. Consolidation, Merger, etc. In case the corporation
                  shall enter into any consolidation,  merger,  combination,  or
                  other  transaction  in which the  shares  of Common  Stock are
                  exchanged for or changed into other stock or securities, cash,
                  and/or any other property, then in any such case each share of
                  Series A Preferred  Stock shall at the same time be  similarly
                  exchanged or changed into an amount per share,  subject to the
                  provision for adjustment  hereinafter set forth, equal to 1000
                  times the aggregate amount of stock, securities,  cash, and/or
                  any other property (payable in kind), as the case may be, into
                  which or for which  each  share of Common  Stock is changed or
                  exchanged.  In the  event  the  corporation  shall at any time
                  declare or pay any  dividend  on the Common  Stock  payable in
                  shares of Common Stock, or effect a subdivision or combination
                  or consolidation of the outstanding shares of Common Stock (by
                  reclassification or otherwise than by payment of a dividend in
                  shares of Common  Stock)  into a greater  or lesser  number of
                  shares of Common Stock,  then in each such case the amount set
                  forth in the  preceding  sentence with respect to the exchange
                  or  change of shares  of  Series A  Preferred  Stock  shall be
                  adjusted  by  multiplying  such  amount  by  a  fraction,  the
                  numerator  of which is the  number of  shares of Common  Stock
                  outstanding  immediately  after such event and the denominator
                  of which is the  number of shares  of Common  Stock  that were
                  outstanding immediately prior to such event.


                                       18.





                  Section 8.  No Redemption.  The shares of Series A
                  Preferred Stock shall not be redeemable.

                  Section 9. Rank. The Series A Preferred Stock shall rank, with
                  respect to the payment of dividends  and the  distribution  of
                  assets,  junior  to all  other  series  of  the  corporation's
                  Preferred Stock.

                  Section 10.  Amendment.  The Articles of  Incorporation of the
                  corporation  shall not be  amended  in any  manner  that would
                  materially alter or change the powers, preferences, or special
                  rights of the Series A  Preferred  Stock so as to affect  them
                  adversely  without the  affirmative  vote of the holders of at
                  least  two-thirds  of  the  outstanding  shares  of  Series  A
                  Preferred Stock, voting together as a single class.

                                   WITNESSETH

         WHEREAS,  the Board of  Directors  of the  Company has  authorized  and
declared a dividend of one preferred  share  purchase right (a "Right") for each
Common Share (as hereinafter defined) of the Company outstanding on September 5,
1996 (the  "Record  Date"),  each Right  representing  the right to purchase one
one-thousandth of a Preferred Share (as hereinafter defined), upon the terms and
subject to the  conditions  herein set forth,  and has  further  authorized  and
directed  the issuance of one Right with respect to each Common Share that shall
become outstanding  between the Record Date and the earliest of the Distribution
Date, the  Redemption  Date,  and the Final  Expiration  Date (as such terms are
hereinafter defined).

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
agreements herein set forth, the parties,  intending to be legally bound, hereby
agree as follows:

     Section  1.  Certain  definitions.  For  purposes  of this  Agreement,  the
following terms have the meanings indicated:

     (a)  "Acquiring  Person" shall mean any Person (as such term is hereinafter
defined) who or which,  together with all  Affiliates  and  Associates  (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as
such term is  hereinafter  defined)  of 15% or more of the Common  Shares of the
Company then outstanding,  but shall not include the Company, any Subsidiary (as
such term is hereinafter  defined) of the Company,  any employee benefit plan of
the

                                       1.





Company or of any Subsidiary of the Company, or any entity holding Common Shares
for or pursuant to the terms of any such plan. Notwithstanding the foregoing:

          (i) no Person shall become an  "Acquiring  Person" as the result of an
     acquisition of Common Shares by the Company  which,  by reducing the number
     of  shares  outstanding,  increases  the  proportionate  number  of  shares
     Beneficially  Owned  by such  Person,  together  with  all  Affiliates  and
     Associates  of such  Person,  to 15% or more of the  Common  Shares  of the
     Company then outstanding;  provided,  however,  that if a Person,  together
     with all  Affiliates  and  Associates  of such  Person,  shall  become  the
     Beneficial  Owner of 15% or more of the Common  Shares of the Company  then
     outstanding  by reason of share  purchases by the Company and shall,  after
     such share  purchases by the Company,  become the  Beneficial  Owner of any
     additional  Common Shares of the Company,  then such Person shall be deemed
     to be an "Acquiring Person;"

          (ii) if the Board of Directors of the Company determines in good faith
     that a Person who would  otherwise  be an  "Acquiring  Person,"  as defined
     pursuant to the foregoing provisions of this paragraph (a), has become such
     inadvertently,  and such  Person  divests  as  promptly  as  practicable  a
     sufficient  number of Common  Shares so that such Person would no longer be
     an "Acquiring  Person," as defined pursuant to the foregoing  provisions of
     this  paragraph  (a),  then  such  Person  shall  not  be  deemed  to be an
     "Acquiring Person" for any purposes of this Agreement.

          (b) "Act" shall mean the Securities Act of 1933, as amended.

          (c)  "Adverse  Change of Control"  shall have the meaning set forth in
     Section 23 hereof.

                                       2.





          (d)  "Affiliate" and  "Associate"  shall have the respective  meanings
     ascribed to such terms in Rule 12b-2 of the General  Rules and  Regulations
     under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
     as in  effect on the date of this  Agreement;  provided,  however,  that no
     director  or  officer  of the  Company  shall be  deemed  an  Affiliate  or
     Associate  of any other  director  or  officer of the  Company  solely as a
     result of his or her being a director or officer of the Company.

          (e) A Person  shall be deemed the  "Beneficial  Owner" of and shall be
     deemed to  "Beneficially  Own" and to have  "Beneficial  Ownership"  of any
     securities:

               (i) which  such  Person  or any of such  Person's  Affiliates  or
          Associates  beneficially  owns,  directly or indirectly (as determined
          pursuant to Rule 13d-3 of the General Rules and Regulations  under the
          Exchange Act as in effect on the date of this Agreement);

               (ii)  which such  Person or any of such  Person's  Affiliates  or
          Associates  has (A) the  right  to  acquire  (whether  such  right  is
          exercisable immediately or only after the passage of time) pursuant to
          any agreement,  arrangement,  or  understanding  (other than customary
          agreements  with and between  underwriters  and selling  group members
          with respect to a bona fide public  offering of  securities),  or upon
          the exercise of conversion rights, exchange rights, rights (other than
          these Rights), warrants or options, or otherwise;  provided,  however,
          that a Person  shall  not be  deemed  the  Beneficial  Owner of, or to
          Beneficially  Own or to have  Beneficial  Ownership of, (1) securities
          tendered  pursuant to a tender or exchange  offer made by or on behalf
          of such Person or any of such Person's  Affiliates or Associates until
          such tendered  securities are accepted for purchase or exchange or (2)
          securities  issuable  upon exercise of the Rights at any time prior to
          the  Distribution  Date;  or (B) the  right  to vote  pursuant  to any
          agreement,  arrangement,  or understanding;  provided, however, that a
          Person

                                       3.





          shall not be deemed the Beneficial Owner of, or to Beneficially Own or
          to have  Beneficial  Ownership  of,  any  security  if the  agreement,
          arrangement,  or understanding to vote such security (1) arises solely
          from a  revocable  proxy  given to such Person in response to a public
          proxy  solicitation  made  pursuant to, and in  accordance  with,  the
          applicable  rules and regulations  promulgated  under the Exchange Act
          and (2) is not also then reportable on Schedule 13D under the Exchange
          Act (or any comparable or successor report); or

               (iii) which are beneficially  owned,  directly or indirectly,  by
          any other  Person  with  which  such  Person  or any of such  Person's
          Affiliates  or  Associates   has  any   agreement,   arrangement,   or
          understanding  (other  than  customary  agreements  with  and  between
          underwriters  and selling  group  members  with respect to a bona fide
          public offering of securities) for the purpose of acquiring,  holding,
          voting  (except to the extent  contemplated  by the proviso to Section
          1(d)(ii)(B)),   or  disposing  of  any   securities  of  the  Company.
          Notwithstanding anything in this definition of Beneficial Ownership to
          the contrary, the

phrase "then  outstanding,"  when used with  reference to a Person's  Beneficial
Ownership of securities of the Company, shall mean the number of such securities
then issued and outstanding together with the number of such securities not then
actually  issued  and  outstanding  that  such  Person  would be  deemed  to own
beneficially hereunder.

     (f) "Business Day" shall mean any day other than a Saturday, a Sunday, or a

     (g) "Close of business"  on any given date shall mean 5:00 P.M.,  New York,
New York  time,  on such  date;  provided,  however,  that if such date is not a

(other than the Company,  any  Subsidiary of the Company,  any employee  benefit
plan of the Company or of any  Subsidiary of the Company,  or any entity holding
Common  Shares for or  pursuant  to the terms of any such plan) to  commence,  a

by such Right Certificates.

     (b) On the Record Date, or as soon as practicable  thereafter,  the Company
will  send a copy of a  Summary  of  Rights to  Purchase  Preferred  Shares,  in
substantially the form of Exhibit C

                                       7.





hereto (the "Summary of Rights"), by first-class,  postage-prepaid mail, to each
record  holder of Common  Shares as of the close of business on the Record Date,
at the address of such holder shown on the records of the Company.  With respect
to certificates for Common Shares  outstanding as of the Record-Date,  until the
Distribution Date, the Rights will be evidenced by such certificates  registered
in the names of the  holders  thereof  together  with a copy of the  Summary  of
Rights  attached  thereto.  Until the  Distribution  Date (or the earlier of the
Redemption Date or the Final Expiration Date), the surrender for transfer of any
certificate for Common Shares  outstanding on the Record Date, with or without a
copy of the  Summary  of Rights  attached  thereto,  shall also  constitute  the
transfer of the Rights associated with the Common Shares represented thereby.

     (c)  Certificates  for Common  Shares that become  outstanding  (including,
without limitation, reacquired Common Shares referred to in the last sentence of
this  paragraph  (c)) after the  Record  Date but prior to the  earliest  of the
Distribution  Date, the Redemption Date, or the Final Expiration Date shall have
impressed on, printed on, written on, or otherwise affixed to them the following
legend:

     This  certificate  also evidences and entitles the holder hereof to certain
     rights as set forth in a Rights Agreement  between Mylan  Laboratories Inc.
     and American Stock  Transfer & Trust  Company,  dated as of August 22, 1996
     (the "Rights Agreement"), the terms of which are hereby incorporated herein
     by  reference  and a copy of  which is on file at the  principal  executive
     offices of Mylan  Laboratories  Inc.  Under certain  circumstances,  as set
     forth in the Rights  Agreement,  such Rights will be  evidenced by separate
     certificates  and will no longer be  evidenced by this  certificate.  Mylan
     Laboratories Inc. will mail to the holder of this certificate a copy of the
     Rights  Agreement  without  charge  after  receipt  of  a  written  request
     therefor.  Under  certain  circumstances,   as  set  forth  in  the  Rights
     Agreement,  Rights  that are or were  beneficially  owned by any Person who
     becomes an Acquiring Person or any Associate or Affiliate of such Acquiring
     Person (as such terms are  defined in the Rights  Agreement)  or  specified
     transferees  of such Acquiring  Person (or Associate or Affiliate  thereof)
     may become null and void.


                                       8.





With respect to such  certificates  containing the foregoing  legend,  until the
Distribution  Date, the Rights associated with the Common Shares  represented by
such  certificates  shall  be  evidenced  by such  certificates  alone,  and the
surrender  for  transfer  of any such  certificate  shall  also  constitute  the
transfer of the Rights associated with the Common Shares represented thereby. In
the event that the Company  purchases  or acquires  any Common  Shares after the
Record Date but prior to the Distribution  Date, any Rights associated with such
Common Shares shall be deemed canceled and retired so that the Company shall not
be entitled to exercise any Rights associated with the Common Shares that are no
longer outstanding.

     Section  4. Form of Right  Certificates.  The Right  Certificates  (and the
forms of election to purchase  Preferred  Shares and of assignment to be printed
on the reverse thereof) shall be substantially  the same as Exhibit B hereto and
may  have  such  marks  of  identification  or  designation  and  such  legends,
summaries,  or endorsements  printed thereon as the Company may deem appropriate
and as are not inconsistent with the provisions of this Agreement,  or as may be
required to comply with any applicable  law or with any rule or regulation  made
pursuant  thereto or with any rule or regulation of any stock  exchange on which
the Rights may from time to time be listed,  or to conform to usage.  Subject to
the  provisions  of  Sections  7, 11,  13,  22,  24,  and 27  hereof,  the Right
Certificates  shall  entitle the holders  thereof to purchase such number of one
one-thousandths  of a Preferred Share as shall be set forth therein at the price
per one  one-thousandth  of a Preferred  Share set forth therein (the  "Purchase
Price"), but the number of such one one-thousandths of a Preferred Share and the
Purchase Price shall be subject to adjustment as provided herein.

     Section 5. Countersignature and Registration.  The Right Certificates shall
be  executed on behalf of the  Company by its  Chairman of the Board,  its Chief
Executive Officer, its President,

                                       9.





any of its Vice  Presidents,  or its Treasurer,  either manually or by facsimile
signature, shall have affixed thereto the Company's seal or a facsimile thereof,
and shall be attested by the Secretary or an Assistant Secretary of the Company,
either  manually or by  facsimile  signature.  The Right  Certificates  shall be
manually  countersigned  by the  Rights  Agent  and  shall  not be valid for any
purpose unless countersigned.  In case any officer of the Company who shall have
signed  any of the Right  Certificates  shall  cease to be such  officer  of the
Company before countersignature by the Rights Agent and issuance and delivery by
the Company, such Right Certificates,  nevertheless, may be countersigned by the
Rights  Agent and issued and  delivered  by the Company  with the same force and
effect as though the person who signed such Right Certificates had not ceased to
be such  officer  of the  Company;  and any Right  Certificate  may be signed on
behalf of the Company by any person who, at the actual date of the  execution of
such Right  Certificate,  shall be a proper  officer of the Company to sign such
Right  Certificate,  although  at the  date  of the  execution  of  this  Rights
Agreement any such person was not such an officer.

     Following the Distribution  Date, the Rights Agent will keep or cause to be
kept, at its principal office,  books for registration and transfer of the Right
Certificates issued hereunder.  Such books shall show the names and addresses of
the respective holders of the Right Certificates, the number of Rights evidenced
on its face by each of the Right Certificates, and the date of each of the Right
Certificates.

     Section  6.  Transfer,  Split  Up,  Combination,   and  Exchange  of  Right
Certificates;  Mutilated, Destroyed, Lost, or Stolen Right Certificates. Subject
to the provisions of Section 14 hereof,  at any time after the close of business
on the  Distribution  Date,  and at or prior to the  close  of  business  on the
earlier  of the  Redemption  Date  or  the  Final  Expiration  Date,  any  Right
Certificate

                                       10.





or Right Certificates  (other than Right Certificates  representing  Rights that
have  become void  pursuant  to Section  7(e)  hereof,  that have been  redeemed
pursuant to Section 23 hereof,  or that have been exchanged  pursuant to Section
24 hereof) may be  transferred,  split up,  combined,  or exchanged  for another
Right  Certificate or Right  Certificates,  entitling the  registered  holder to
purchase a like number of one  one-thousandths of a Preferred Share as the Right
Certificate  or Right  Certificates  surrendered  then  entitled  such holder to
purchase.  Any registered  holder desiring to transfer,  split up,  combine,  or
exchange any Right Certificate or Right  Certificates shall make such request in
writing delivered to the Rights Agent, and shall surrender the Right Certificate
or Right Certificates to be transferred, split up, combined, or exchanged at the
principal  office  of  the  Rights  Agent.  Thereupon  the  Rights  Agent  shall
countersign  and deliver to the person entitled  thereto a Right  Certificate or
Right Certificates, as the case may be, as so requested. The Company may require
payment of a sum sufficient to cover any tax or governmental  charge that may be
imposed in connection with any transfer,  split up, combination,  or exchange of
Right Certificates.

     Upon  receipt by the  Company and the Rights  Agent of evidence  reasonably
satisfactory to them of the loss, theft,  destruction,  or mutilation of a Right
Certificate,  and, in case of loss,  theft,  or  destruction,  of  indemnity  or
security  reasonably  satisfactory  to  them,  and,  at the  Company's  request,
reimbursement  to the Company and the Rights  Agent of all  reasonable  expenses
incidental  thereto,  and upon surrender to the Rights Agent and cancellation of
the Right  Certificate  if  mutilated,  the Company  will make and deliver a new
Right  Certificate  of like  tenor  to the  Rights  Agent  for  delivery  to the
registered holder in lieu of the Right Certificate so lost,  stolen,  destroyed,
or mutilated.

     Section 7. Exercise of Rights; Purchase Price; Expiration Date of Rights.

                                                        11.





     (a) Subject to Section  7(e)  hereof,  the  registered  holder of any Right
Certificate  may  exercise  the Rights  evidenced  thereby  (except as otherwise
provided  herein)  in whole or in part at any time after the  Distribution  Date
upon surrender of the Right  Certificate,  with the form of election to purchase
on the reverse side thereof duly executed,  to the Rights Agent at the principal
office of the Rights Agent designated for such purpose, together with payment of
the Purchase Price for each one  one-thousandth of a Preferred Share (or after a
Triggering  Event, the securities,  cash,  and/or other property  purchasable in
lieu thereof) as to which the Rights are exercised,  at or prior to the earliest
of (i) the close of business on September 5, 2006 (the "Final Expiration Date"),
(ii) the time at which the Rights are  redeemed as provided in Section 23 hereof
(the "Redemption Date"), or (iii) the time at which such Rights are exchanged as
provided in Section 24 hereof.

     (b) The Purchase  Price for each one  one-thousandth  of a Preferred  Share
purchasable  pursuant to the  exercise of a Right shall  initially  be $90,  and
shall be subject to adjustment from time to time as provided in Section 11 or 13
hereof and shall be payable in lawful  money of the United  States of America in
accordance with paragraph (c) below.

     (c) Upon receipt of a Right Certificate  representing  exercisable  Rights,
with the form of election to purchase duly  executed,  accompanied by payment of
the  Purchase  Price for the shares to be  purchased  and an amount equal to any
applicable  transfer  tax  required  to be paid  by the  holder  of  such  Right
Certificate in accordance  with Section 9 hereof by certified  check,  cashier's
check,  or money order  payable to the order of the  Company,  the Rights  Agent
shall  thereupon  promptly (i) (A)  requisition  from any transfer  agent of the
Preferred Shares certificates for the number of Preferred Shares to be purchased
and the Company hereby irrevocably  authorizes its transfer agent to comply with
all such  requests,  or (B)  requisition  from the depositary  agent  depositary
receipts representing

                                       12.





such number of one  one-thousandths  of a Preferred Share as are to be purchased
(in  which  case  certificates  for the  Preferred  Shares  represented  by such
receipts shall be deposited by the transfer agent with the depositary agent) and
the Company  hereby  directs the  depositary  agent to comply with such request,
(ii) when  appropriate,  requisition  from the  Company the amount of cash to be
paid in lieu of issuance of  fractional  shares in  accordance  with  Section 14
hereof, (iii) after receipt of such certificates or depositary  receipts,  cause
the same to be delivered to or upon the order of the  registered  holder of such
Right Certificate, registered in such name or names as may be designated by such
holder, and (iv) when appropriate,  after receipt,  deliver such cash to or upon
the order of the registered holder of such Right Certificate.  In the event that
the  Company is  obligated,  upon the  exercise  of any  Rights,  to issue other
securities  (including  Common  Shares) of the  Company or other  property,  the
Company will make all  arrangements  necessary so that such other  securities or
property  are  available  for  distribution  by the  Rights  Agent,  if and when
appropriate.

     (d) In case the registered  holder of any Right  Certificate shall exercise
less than all the Rights evidenced thereby,  a new Right Certificate  evidencing
Rights  equivalent to the Rights  remaining  unexercised  shall be issued by the
Rights Agent to the registered  holder of such Right  Certificate or to his duly
authorized assigns, subject to the provisions of Section 14 hereof.

     (e)  Notwithstanding  anything in this Agreement to the contrary,  from and
after the time that any Person becomes an Acquiring Person,  any Rights that are
or were  acquired  or  Beneficially  Owned by (i) any  Acquiring  Person (or any
Associate or Affiliate of such  Acquiring  Person);  (ii) any  transferee  of an
Acquiring  Person (or any Associate or Affiliate of such  Acquiring  Person) who

transferee  of an  Acquiring  Person  (or any  Associate  or  Affiliate  of such

or concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer (whether or not for  consideration)  from such
Acquiring  Person (or any  Affiliate or Associate of such  Acquiring  Person) to
holders  of equity  interests  in such  Acquiring  Person (or any  Affiliate  or
Associate of such  Acquiring  Person) or to any Person with whom such  Acquiring
Person  (or any  Affiliate  or  Associate  of  such  Acquiring  Person)  has any
continuing written or oral agreement or understanding  regarding the transferred
Rights  or (B) a  transfer  that  the  Board of  Directors  of the  Company  has
determined in good faith is part of a plan,  arrangement,  or understanding that
has as a primary purpose or effect the avoidance of this Section 7(e),  shall be
null and void  without any further  action,  and any holder of such Rights shall
thereafter have no rights whatsoever with respect to such Rights,  whether under
any provision of this  Agreement or otherwise  (including,  without  limitation,
rights pursuant to Sections 7, 11, 13, 23, and 24 hereof).  No Right Certificate
shall be issued  pursuant  to  Section 3 or Section  22 hereof  that  represents
Rights  Beneficially  Owned by any Person whose Rights would be void pursuant to
the  preceding  sentence;  no  Right  Certificate  shall be  issued  at any time
pursuant to Section 6 hereof  upon the  transfer of any Rights to any Person (or
any nominee of such Person) whose Rights would be void pursuant to the preceding
sentence upon such transfer;  no Right  Certificate  shall be issued at any time
pursuant  to  Section  6 or  Section  11  hereof  upon the  transfer,  split up,
combination,  exchange,  replacement,  or adjustment of any Rights  Beneficially
Owned by any Person (or any nominee of such  Person)  whose Rights would be void
pursuant to the preceding sentence;  and any Right Certificate  delivered to the
Rights Agent for  transfer to any Person (or any nominee of such  Person)  whose
Rights would be void pursuant to the preceding  sentence shall be canceled.  The
Company  shall  use  all  reasonable  efforts  to  insure  compliance  with  the
provisions  of this Section  7(e),  but shall have no liability to any holder of
Right

Certificates  or any  other  Person  as a  result  of its  failure  to make  any
determinations  hereunder with respect to an Acquiring Person or its Affiliates,
Associates, or transferees.

     (f) Notwithstanding anything in this Agreement to the contrary, neither the
Rights Agent nor the Company  shall be  obligated  to undertake  any action with
respect to a registered holder upon the occurrence of any purported  exercise as
set  forth in this  Section  7 unless  such  registered  holder  shall  have (i)
completed  and signed  the  certificate  contained  in the form of  election  to
purchase set forth on the reverse side of the Right Certificate  surrendered for
such exercise, and (ii) provided such additional evidence of the identity of the
Beneficial  Owner (or  former  Beneficial  Owner) or  Affiliates  or  Associates
thereof as the Company shall reasonably request.

     Section 8.  Cancellation and Destruction of Right  Certificates.  All Right
Certificates  surrendered  for the  purpose  of  exercise,  transfer,  split up,
combination,  or exchange  shall, if surrendered to the Company or to any of its
agents,  be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered  to the Rights Agent,  shall be cancelled by it, and no Right
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
any of the provisions of this Rights Agreement. The Company shall deliver to the
Rights  Agent for  cancellation  and  retirement,  and the Rights Agent shall so
cancel and retire,  any other  Right  Certificate  purchased  or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all  cancelled  Right  Certificates  to the  Company,  or shall,  at the written
request of the Company,  destroy such cancelled Right Certificates,  and in such
case shall deliver a certificate of destruction thereof to the Company.

     Section 9. Reservation and Availability of Capital Stock.

                                       15.





     (a) The Company  covenants and agrees that it will cause to be reserved and
kept  available  out of its  authorized  and  unissued  Preferred  Shares or any
Preferred  Shares held in its  treasury  (and,  following  the  occurrence  of a
Triggering  Event, out of its authorized and unissued Common Shares and/or other
securities  or out  of  any  Common  Shares  or  other  securities  held  in its
treasury),  the number of Preferred  Shares (and,  following the occurrence of a
Triggering Event, Common Shares and/or other securities) that will be sufficient
to permit the exercise in full of all outstanding Rights in accordance with this
Agreement.

     (b) So long as the Preferred  Shares (and,  following  the  occurrence of a
Triggering  Event,   Common  Shares  and/or  other   securities)   issuable  and
deliverable  upon the  exercise  of the  Rights  may be listed  on any  national
securities  exchange or automated  quotation  system,  the Company shall use its
best  efforts  to  cause,  from  and  after  such  time  as  the  Rights  become
exercisable, all shares reserved for such issuance to be listed on such exchange
or quotation system upon official notice of issuance upon such exercise.

     (c) The  Company  shall  use  its  best  efforts  to (i)  file,  as soon as
practicable  following the earliest date after the first  occurrence of an event
described in Section 11(a)(ii) hereof on which the consideration to be delivered
by the Company upon  exercise of the Rights has been  determined  in  accordance
with Section  11(a)(iii)  hereof,  or as soon as required by law  following  the
Distribution  Date, as the case may be, a registration  statement  under the Act
with respect to the  securities  purchasable  upon  exercise of the Rights on an
appropriate form, (ii) cause such registration  statement to become effective as
soon as  practicable  after  such  filing,  and (iii)  cause  such  registration
statement  to remain  effective  (with a  prospectus  at all times  meeting  the
requirements  of the Act)  until  the  earlier  of (A) the date as of which  the
Rights are no longer exercisable for such securities, and (B)

                                       16.





the date of the expiration of the Rights. The Company will also take such action
as may be appropriate  under,  or to ensure  compliance  with, the securities or
"blue sky" laws of the various states in connection with the  exercisability  of
the Rights.  The Company may  temporarily  suspend,  for a period of time not to
exceed 90 days after the date set forth in clause (i) of the first  sentence  of
this Section 9(c), the exercisability of the Rights in order to prepare and file
such  registration  statement and permit it to become  effective.  Upon any such
suspension,  the Company  shall  issue a public  announcement  stating  that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement  at such time as the suspension is no longer in effect stating that
the  suspension  on the  exercisability  of the  Rights is no longer in  effect.
Notwithstanding  any  provision of this  Agreement to the  contrary,  the Rights
shall not be exercisable in any jurisdiction (x) if the requisite  qualification
in such  jurisdiction  shall not have  been  obtained  and until a  registration
statement has been declared  effective or (y) if the exercise  thereof shall not
be permitted under applicable law.

     (d) The Company  covenants  and agrees that it will take all such action as
may be necessary  to ensure that all one  one-thousandths  of a Preferred  Share
(and following the occurrence of a Triggering Event,  Common Shares and/or other
securities)  delivered upon exercise of Rights shall, at the time of delivery of
the certificates for such shares (subject to payment of the Purchase Price),  be
duly and validly authorized and issued and fully paid and nonassessable.

     (e) The Company further  covenants and agrees that it will pay when due and
payable  any and all federal and state  transfer  taxes and charges  that may be
payable in respect of the issuance or delivery of the Right  Certificates  or of
any  certificates or depositary  receipts for Preferred Shares (or Common Shares
and/or other securities, as the case may be) upon exercise of the Rights. The

                                                        17.





Company  shall not,  however,  be required to pay any  transfer  tax that may be
payable in respect of any transfer or delivery of Right Certificates to a person
other than, or the issuance or delivery of certificates  or depositary  receipts
for the Preferred Shares (or Common shares and/or other securities,  as the case
may be) in a name  other  than  that of,  the  registered  holder  of the  Right
Certificates  evidencing  Rights  surrendered  for  exercise  or to  issue or to
deliver any certificates or depositary receipts for Preferred Shares (or Commons
Shares and/or other securities, as the case may be) in a name other than that of
the  registered  holder upon the exercise of any Rights until any such tax shall
have  been  paid  (any  such tax  being  payable  by the  holder  of such  Right
Certificate  at the time of surrender) or until it has been  established  to the
Company's reasonable satisfaction that no such tax is due.

     Section 10.  Preferred  Shares  Record Date.  Each person in whose name any
certificate for Preferred Shares is issued upon the exercise of Rights shall for
all  purposes  be deemed to have  become the  holder of record of the  Preferred
Shares  represented  thereby on, and such  certificate  shall be dated, the date
upon which the Right Certificate evidencing such Rights was duly surrendered and
payment of the  Purchase  Price (and any  applicable  transfer  taxes) was made;
provided, however, that if the date of such surrender and payment is a date upon
which the Preferred Shares transfer books of the Company are closed, such person
shall be deemed to have  become  the record  holder of such  shares on, and such
certificate  shall be  dated,  the next  succeeding  Business  Day on which  the
Preferred  Shares transfer books of the Company are open.  Prior to the exercise
of the Rights evidenced thereby,  the holder of a Right Certificate shall not be
entitled  to any  rights of a holder of  Preferred  Shares  for which the Rights
shall be exercisable, including, without limitation, the right

                                       18.





to vote,  to  receive  dividends  or other  distributions,  or to  exercise  any
preemptive  rights,  and shall not be  entitled  to  receive  any  notice of any
proceedings of the Company, except as provided herein.

     Section 11.  Adjustment of Purchase Price,  Number of Shares,  or Number of
Rights.  The  Purchase  Price,  the number of Preferred  Shares  covered by each
Right, and the number of Rights  outstanding are subject to adjustment from time
to time as provided in this Section 11.

     (a)(i) In the event the  Company  shall at any time  after the date of this
Agreement  (A) declare a dividend on the Preferred  Shares  payable in Preferred
Shares,  (B)  subdivide  the  outstanding  Preferred  Shares,  (C)  combine  the
outstanding  Preferred Shares into a smaller number of Preferred  Shares, or (D)
issue any shares of its capital  stock in a  reclassification  of the  Preferred
Shares (including any such  reclassification  in connection with a consolidation
or merger in which the  Company is the  continuing  or  surviving  corporation),
except as otherwise provided in this Section 11(a), the Purchase Price in effect
at the time of the record  date for such  dividend or of the  effective  date of
such subdivision,  combination, or reclassification,  and the number and kind of
shares of capital stock issuable on such date, shall be proportionately adjusted
so that the holder of any Right  exercised  after such time shall be entitled to
receive the  aggregate  number and kind of shares of capital stock that, if such
Right had been exercised  immediately  prior to such date and at a time when the
Preferred  Shares  transfer  books of the Company were open, he would have owned
upon such  exercise  and been  entitled  to receive by virtue of such  dividend,
subdivision,  combination,  or  reclassification.  If an event occurs that would
require an  adjustment  under both this Section  11(a)(i) and Section  11(a)(ii)
hereof,  the  adjustment  provided  for in this  Section  11(a)(i)  shall  be in
addition  to, and shall be made prior to, any  adjustment  required  pursuant to
Section 11(a)(ii) hereof.

                                       19.





     (ii) Subject to Sections  7(e),  13(a),  and 24 of this  Agreement,  in the
event any Person  becomes an  Acquiring  Person,  each  holder of a Right  shall
thereafter  have a right to receive,  upon exercise  thereof at a price equal to
the then current Purchase Price multiplied by the number of one  one-thousandths
of a Preferred Share for which a Right is then  exercisable,  in accordance with
the terms of this  Agreement  and in lieu of  Preferred  Shares,  such number of
Common  Shares  of the  Company  as  shall  equal  the  result  obtained  by (x)
multiplying the then current Purchase Price by the number of one one-thousandths
of a Preferred  Share for which a Right is then  exercisable  and dividing  that
Product by (y) 50% of the then current per share  market price of the  Company's
Common Shares  (determined  pursuant to Section 11(d) hereof) on the date of the
occurrence of such event.

     (iii) In the event that there shall not be sufficient  Common Shares issued
but not outstanding or authorized but unissued to permit the exercise in full of
the Rights in accordance with the foregoing subparagraph (ii), the Company shall
substitute, for each Common Share that would otherwise be issuable upon exercise
of a Right,  a number of  Preferred  Shares or  fraction  thereof  such that the
current per share market price of one Preferred Share  multiplied by such number
or fraction is equal to the current per share  market  price of one Common Share
as of the date of issuance of such Preferred Shares or fraction thereof.  In the
event there shall not be sufficient  Preferred Shares issued but not outstanding
or  authorized  but  unissued  to permit the  exercise  in full of the Rights in
accordance  with the  foregoing  sentence,  the Company shall take all action as
shall be necessary to authorize  additional  Preferred  Shares for issuance upon
exercise of the Rights. In the event the Company shall, after good faith effort,
be unable to take action  sufficient  to  authorize  such  additional  Preferred
Shares, the Company shall take all such action as may be necessary to authorize,
issue or

                                       20.





pay, upon the exercise of the Rights,  cash  (including by way of a reduction of
the Purchase  Price),  property,  other  securities or any  combination  thereof
having an  aggregate  value  equal to the value of the  Preferred  Shares of the
Company which otherwise would have been issuable  pursuant to the first sentence
of this Section  11(a)(iii),  which  aggregate value shall be determined in good
faith by a majority of the Board of  Directors.  For  purposes of the  preceding
sentence, the value of the Preferred Shares shall be determined pursuant Section
11(d)  hereof and the value of any  equity  securities  which a majority  of the
Board of  Directors  determines  in good  faith to be  equivalent  to the Common
Shares or "equivalent  preferred  shares" (as defined in Section 11(b)) shall be
deemed  to have the  same  value  as the  Common  Shares  or  Preferred  Shares,
respectively.  Any  substitution of securities,  property and/or cash under this
Section 11(a)(iii) shall be made and publicly announced within 60 days after the
date any Person becomes an Acquiring Person

     (b) In case the Company shall fix a record date for the issuance of rights,
options,  or warrants to all holders of Preferred  Shares  entitling them (for a
period expiring within 45 calendar days after such record date) to subscribe for
or purchase Preferred Shares (or shares having the same rights,  privileges, and
preferences  as  the  Preferred  Shares  ("equivalent   preferred  shares"))  or
securities convertible into Preferred Shares or equivalent preferred shares at a
price per Preferred Share or equivalent  preferred share (or having a conversion
price per share, if a security  convertible  into Preferred Shares or equivalent
preferred  shares)  less than the then  current  per share  market  price of the
Preferred Shares (as defined in Section 11(d)) on such record date, the Purchase
Price to be in effect after such record date shall be determined by  multiplying
the  Purchase  Price  in  effect  immediately  prior  to such  record  date by a
fraction,  the  numerator  of which  shall be the  number  of  Preferred  Shares
outstanding on such record date plus the number of Preferred Shares that the

                                       21.





aggregate  offering  price  of the  total  number  of  Preferred  Shares  and/or
equivalent  preferred  shares so to be offered  (and/or  the  aggregate  initial
conversion price of the convertible  securities so to be offered) would purchase
at such current market price and the denominator of which shall be the number of
Preferred  Shares  outstanding on such record date plus the number of additional
Preferred  Shares  and/or   equivalent   preferred  shares  to  be  offered  for
subscription  or purchase  (or into which the  convertible  securities  so to be
offered are initially convertible).  In case such subscription price may be paid
in a consideration  part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent.  Preferred  Shares owned by or held for the account
of the  Company  shall not be deemed  outstanding  for the  purpose  of any such
computation.  Such adjustment shall be made successively  whenever such a record
date is fixed; and in the event that such rights,  options,  or warrants are not
so issued,  the Purchase  Price shall be adjusted to be the Purchase  Price that
would then be in effect if such record date had not been fixed.

     (c) In case the  Company  shall  fix a  record  date  for the  making  of a
distribution  to all  holders  of  the  Preferred  Shares  (including  any  such
distribution  made in  connection  with a  consolidation  or merger in which the
Company is the continuing or surviving corporation) of evidences of indebtedness
or assets (other than a regular quarterly cash dividend or a dividend payable in
Preferred Shares) or subscription  rights or warrants  (excluding those referred
to in Section  11(b)  hereof),  the  Purchase  Price to be in effect  after such
record date shall be  determined  by  multiplying  the Purchase  Price in effect
immediately  prior to such  record date by a fraction,  the  numerator  of which
shall be the then current per share market price of the Preferred Shares on such

                                       22.





record  date,  less the fair market  value (as  determined  in good faith by the
Board of Directors of the Company,  whose  determination shall be described in a
statement filed with the Rights Agent) of the portion of the assets or evidences
of indebtedness so to be distributed or of such subscription  rights or warrants
applicable to one  Preferred  Share and the  denominator  of which shall be such
current per share market price of the Preferred  Shares.  Such adjustments shall
be made successively whenever such a record date is fixed; and in the event that
such  distribution is not so made, the Purchase Price shall again be adjusted to
be the  Purchase  Price that would then be in effect if such record date had not
been fixed.

     (d)(i) For the purpose of any computation hereunder, the "current per share
market  price" of any  security (a  "Security"  for the purpose of this  Section
11(d)(i))  on any date shall be deemed to be the  average  of the daily  closing
prices per share of such Security for the 30  consecutive  Trading Days (as such
term is hereinafter defined) immediately prior to such date; provided,  however,
that in the event that the current  per share  market  price of the  Security is
determined  during a period  following  the  announcement  by the issuer of such
Security of (A) a dividend or distribution on such Security payable in shares of
such  Security  or  securities   convertible  into  such  shares,   or  (B)  any
subdivision,  combination, or reclassification of such Security and prior to the
expiration  of 30 Trading Days after the  ex-dividend  date for such dividend or
distribution,  or  the  record  date  for  such  subdivision,   combination,  or
reclassification,  then,  and in each such case,  the current  per share  market
price shall be  appropriately  adjusted to reflect the current  market price per
share  equivalent of such Security.  The closing price for each day shall be the
last sale price,  regular way, or, in case no such sale takes place on such day,
the average of the closing bid and asked prices,  regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to

                                       23.





securities  listed or admitted to trading on the New York Stock  Exchange or, if
the  Security  is not  listed  or  admitted  to  trading  on the New York  Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national  securities exchange
on which the  Security is listed or  admitted to trading or, if the  Security is
not listed or admitted to trading on any national securities exchange,  the last
quoted  price or, if not so  quoted,  the  average of the high bid and low asked
prices in the  over-the-counter  market, as reported by the National Association
of Securities Dealers, Inc. Automated Quotations System ("NASDAQ") or such other
system  then in use,  or, if on any such date the  Security is not quoted by any
such organization,  the average of the closing bid and asked prices as furnished
by a professional  market maker making a market in the Security  selected by the
Board of Directors of the Company.  The term  "Trading  Day" shall mean a day on
which the principal national securities exchange on which the Security is listed
or  admitted  to  trading is open for the  transaction  of  business  or, if the
Security  is not  listed or  admitted  to  trading  on any  national  securities
exchange, a Business Day.

     (ii) For the purpose of any computation  hereunder,  the "current per share
market price" of the Preferred Shares shall be determined in accordance with the
method set forth in Section  11(d)(i).  If the Preferred Shares are not publicly
traded,  the "current per share market price" of the  Preferred  Shares shall be
conclusively  deemed to be the  current  per share  market  price of the  Common
Shares as determined  pursuant to Section  11(d)(i)  (appropriately  adjusted to
reflect any stock split, stock dividend,  or similar transaction occurring after
the date  hereof),  multiplied  by 1,000.  If neither the Common  Shares nor the
Preferred  Shares are publicly  held or so listed or traded,  "current per share
market price" shall mean the fair value per share as determined in good

                                       24.





faith by the Board of  Directors of the Company,  whose  determination  shall be
described in a statement filed with the Rights Agent.

     (e) No  adjustment  in the  Purchase  Price shall be  required  unless such
adjustment  would require an increase or decrease of at least 1% in the Purchase
Price;  provided,  however, that any adjustments which by reason of this Section
11(e) are not  required  to be made  shall be  carried  forward  and taken  into
account in any subsequent  adjustment.  All  calculations  under this Section 11
shall be made to the  nearest  cent or to the  nearest  one  one-millionth  of a
Preferred Share or one ten-thousandth of any other share or security as the case
may be. Notwithstanding the first sentence of this Section 11(e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
years from the date of the transaction that requires such adjustment or (ii) the
date of the expiration of the right to exercise any Rights.

     (f) If as a result of an adjustment  made pursuant to Section 11(a) hereof,
the holder of any Right  thereafter  exercised  shall become entitled to receive
any  shares  of  capital  stock of the  Company  other  than  Preferred  Shares,
thereafter  the number of such other shares so  receivable  upon exercise of any
Right shall be subject to adjustment  from time to time in a manner and on terms
as nearly  equivalent  as  practicable  to the  provisions  with  respect to the
Preferred  Shares  contained in Section  11(a) through (c),  inclusive,  and the
provisions  of Sections 7, 9, 10, and 13 with  respect to the  Preferred  Shares
shall apply on like terms to any such other shares.

     (g)  All  Rights  originally  issued  by  the  Company  subsequent  to  any
adjustment  made to the Purchase  Price  hereunder  shall  evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-thousandths of a
Preferred  Share  purchasable  from time to time  hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

                                       25.





     (h) Unless the Company  shall have  exercised  its  election as provided in
Section  11(i),  upon each  adjustment of the Purchase  Price as a result of the
calculations made in Sections 11(b) and (c), each Right outstanding  immediately
prior to the making of such adjustment  shall  thereafter  evidence the right to
purchase,  at the adjusted Purchase Price, that number of one one-thousandths of
a Preferred Share  (calculated to the nearest one  one-millionth  of a Preferred
Share) obtained by (i) multiplying  (x) the number of one  one-thousandths  of a
share  covered  by a  Right  immediately  prior  to this  adjustment  by (y) the
Purchase Price in effect  immediately  prior to such  adjustment of the Purchase
Price and (ii) dividing the product so obtained by the Purchase  Price in effect
immediately after such adjustment of the Purchase Price.

     (i) The  Company  may elect on or after the date of any  adjustment  of the
Purchase  Price  to  adjust  the  number  of  Rights,  in  substitution  for any
adjustment  in  the  number  of  one  one-  thousandths  of  a  Preferred  Share
purchasable upon the exercise of a Right.  Each of the Rights  outstanding after
such  adjustment of the number of Rights shall be exercisable  for the number of
one  one-thousandths  of a  Preferred  Share for  which a Right was  exercisable
immediately  prior to such  adjustment.  Each Right held of record prior to such
adjustment  of  the  number  of  Rights  shall  become  that  number  of  Rights
(calculated to the nearest one ten-thousandth) obtained by dividing the Purchase
Price in effect  immediately  prior to adjustment  of the Purchase  Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights,  indicating  the record  date for the  adjustment,  and, if known at the
time, the amount of the adjustment to be made.  This record date may be the date
on which the Purchase Price is adjusted or any day thereafter, but, if the Right
Certificates have been issued,  shall be at least 10 days later than the date of
the public

                                       26.





announcement.  If Right  Certificates have been issued,  upon each adjustment of
the number of Rights  pursuant to this  Section  11(i),  the Company  shall,  as
promptly as  practicable,  cause to be distributed to holders of record of Right
Certificates  on such record date Right  Certificates  evidenc  ing,  subject to
Section 14 hereof, the additional Rights to which such holders shall be entitled
as a result of such adjustment, or, at the option of the Company, shall cause to
be distributed to such holders of record in substitution and replacement for the
Right  Certificates  held by such holders prior to the date of  adjustment,  and
upon  surrender  thereof,  if required by the  Company,  new Right  Certificates
evidencing  all the Rights to which such  holders  shall be entitled  after such
adjustment.  Right Certificates so to be distributed shall be issued,  executed,
and  countersigned  in the manner provided for herein and shall be registered in
the names of the  holders of record of Right  Certificates  on the  record  date
specified in the public announcement.

     (j)  Irrespective  of any adjustment or change in the Purchase Price or the
number of one one-thousandths of a Preferred Share issuable upon the exercise of
the  Rights,  the Right  Certificates  theretofore  and  thereafter  issued  may
continue to express the Purchase Price and the number of one  one-thousandths of
a Preferred Share that were expressed in the initial Right  Certificates  issued
hereunder.

     (k) In any case in which this Section 11 shall  require that an  adjustment
in the  Purchase  Price be made  effective  as of a record  date for a specified
event,  the Company may elect to defer  until the  occurrence  of such event the
issuing  to the holder of any Right  exercised  after  such  record  date of the
Preferred  Shares and other capital stock or securities of the Company,  if any,
issuable  upon  such  exercise  over and above the  Preferred  Shares  and other
capital stock or securities of the Company,  if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to

                                       27.





such  adjustment;  provided,  however,  that the Company  shall  deliver to such
holder a due bill or other appropriate instrument evidencing such holder's right
to receive such  additional  shares upon the  occurrence of the event  requiring
such adjustment.

     (l)  Anything  in this  Section  11 to the  contrary  notwithstanding,  the
Company  shall be entitled to make such  reductions  in the Purchase  Price,  in
addition to those adjustments  expressly  required by this Section 11, as and to
the extent that it in its sole  discretion  shall  determine  to be advisable in
order that any  consolidation or subdivision of the Preferred  Shares,  issuance
wholly for cash of any Preferred  Shares at less than the current  market price,
issuance wholly for cash of Preferred  Shares or securities which by their terms
are  convertible  into  or  exchangeable  for  Preferred  Shares,  dividends  on
Preferred Shares payable in Preferred Shares, or issuance of rights, options, or
warrants referred to hereinabove in Section 11(b), hereafter made by the Company
to holders of its Preferred Shares, shall not be taxable to such shareholders.

     (m) In the  event  that at any time  after the date of this  Agreement  and
prior to the  Distribution  Date,  the  Company  shall  (i)  declare  or pay any
dividend  on the  Common  Shares  payable  in  Common  Shares  or (ii)  effect a
subdivision,   combination   or   consolidation   of  the   Common   Shares  (by
reclassification  or otherwise  than by payment of  dividends in Common  Shares)
into a greater or lesser number of Common Shares,  then in any such case (A) the
number of one  one-thousandths of a Preferred Share purchasable after such event
upon proper exercise of each Right shall be determined by multiplying the number
of one one-thousandths of a Preferred Share so purchasable  immediately prior to
such event by a fraction,  the numerator of which is the number of Common Shares
outstanding  immediately  before such event and the  denominator of which is the
number of Common Shares  outstanding  immediately after such event, and (B) each
Common Share outstanding

                                       28.





immediately after such event shall have issued with respect to it that number of
Rights that each Common Share  outstanding  immediately  prior to such event had
issued with respect to it. The  adjustments  provided for in this Section  11(n)
shall be made successively  whenever such a dividend is declared or paid or such
a subdivision, combination, or consolidation is effected.

     (n) The Company  covenants and agrees that, after the Distribution Date and
so long as any Rights  shall then be  outstanding  (other  than Rights that have
become void pursuant to Section 7(e) hereof),  it will not,  except as permitted
by Sections 23, 24, and 27 hereof, take (or permit any Subsidiary of the Company
to  take)  any  action  if at the time  such  action  is taken it is  reasonably
foreseeable that such action will diminish  substantially or otherwise eliminate
the benefits intended to be afforded by the Rights.

     Section 12.  Certificate  of Adjusted  Purchase  Price or Number of Shares.
Whenever  an  adjustment  is made as  provided  in Section 11 or 13 hereof,  the
Company shall promptly (a) prepare a certificate  setting forth such adjustment,
and a brief statement of the facts accounting for such adjustment, (b) file with
the  Rights  Agent and with each  transfer  agent for the  Common  Shares or the
Preferred  Shares  a copy of such  certificate,  and  (c)  mail a brief  summary
thereof  to each  registered  holder of a Right in  accordance  with  Section 26
hereof.

     Section 13. Consolidation, Merger, or Sale or Transfer of Assets or Earning
Power.

     (a) In the event,  directly or  indirectly,  at any time after a Person has
become an Acquiring  Person,  (x) the Company shall  consolidate  with, or merge
with and into,  any other Person (other than a direct or indirect,  wholly-owned
Subsidiary  of the Company in a  transaction  that  complies  with Section 11(o)
hereof), and the Company shall not be the continuing or surviving corporation of
such  consolidation or merger,  (y) any Person (other than a direct or indirect,
wholly-owned Subsidiary of

                                       29.





the Company in a  transaction  that  complies  with Section  11(o) hereof) shall
consolidate  with the  Company,  or merge  with  and into the  Company,  and the
Company shall be the continuing or surviving  corporation of such  consolidation
or merger and, in connection with such merger,  all or part of the Common Shares
shall be changed into or exchanged  for stock or other  securities  of any other
Person (or the Company) or cash or any other property,  or (z) the Company shall
sell or  otherwise  transfer (or one or more of its  Subsidiaries  shall sell or
otherwise  transfer),  in one or more  transactions,  assets  or  earning  power
aggregating  50% or more of the assets or earning  power of the  Company and its
Subsidiaries  (taken as a whole) to any other Person or Persons  (other than the
Company or one or more of its direct or indirect,  wholly-owned  Subsidiaries in
one or more  transactions each of which complies with Section 11(o) hereof) (any
event  described in (x), (y), or (z) being referred to hereinafter as a "Section
13(a) Event"),  then, and in each such case,  proper  provision shall be made so
that (i) each holder of a Right  (except as  otherwise  provided  herein)  shall
thereafter have the right to receive, upon the exercise thereof at a price equal
to  the  then  current   Purchase   Price   multiplied  by  the  number  of  one
one-thousandths  of a Preferred Share for which a Right is then exercisable,  in
accordance  with the terms of this  Agreement  and in lieu of Preferred  Shares,
such number of Common Shares of the Principal Party (as such term is hereinafter
defined),  not subject to any liens,  encumbrances,  rights of first refusal, or
other adverse claims,  as shall equal the result obtained by (A) multiplying the
then current Purchase Price by the number of one one- thousandths of a Preferred
Share for which a Right is then  exercisable,  and dividing  that product by (B)
50% of the then  current  per share  market  price of the  Common  Shares of the
Principal  Party  (determined  pursuant to Section  11(d) hereof) on the date of
consummation  of such  Section  13(a)  Event;  (ii) such  Principal  Party shall
thereafter be liable for, and shall assume, by virtue of such

                                       30.





Section 13(a) Event,  all the obligations and duties of the Company  pursuant to
this Agreement;  (iii) the term "Company" shall thereafter be deemed to refer to
such  Principal  Party,  it being  specifically  intended that the provisions of
Section 11 hereof shall apply only to such Principal  Party  following the first
occurrence of a Section 13(a) Event;  (iv) such Principal  Party shall take such
steps (including,  but not limited to, the reservation of a sufficient number of
its Common Shares in accordance  with Section 9 hereof) in connection  with such
consummation  as may be  necessary  to assure that the  provisions  hereof shall
thereafter be  applicable,  as nearly as  reasonably  may be, in relation to the
Common Shares  thereafter  deliverable upon the exercise of the Rights;  and (v)
the provisions of Section  11(a)(ii)  hereof shall be of no effect following the
first  occurrence  of a  Section  13(a)  Event  and the  Rights  that  have  not
theretofore  been exercised shall  thereafter  become  exercisable in the manner
described in this Section 13.

     (b) "Principal Party" shall mean:

          (i) in the case of any  transaction  described in clause (x) or (y) of
     the first sentence of Section 13(a),  the Person  (including the Company as
     successor  thereto or as the surviving  corporation)  that is the issuer of
     any  securities or other equity  interests  into which Common Shares of the
     Company are converted in such merger or consolidation, and if no securities
     are so issued, the Person (including the Company as successor thereto or as
     the  surviving  corporation)  that is the other  constituent  party to such
     merger or consolidation; and

          (ii) in the case of any  transaction  described  in clause  (z) of the
     first sentence of Section 13(a), the Person that is the party receiving the
     greatest  portion of the assets or earning  power  transferred  pursuant to
     such transaction or transactions; provided, however, that in any such case,
     (1) if the Common Shares of such Person are not at such time and have

                                       31.





     not been  continuously  over the preceding 12 month period registered under
     Section 12 of the  Exchange  Act,  and such  Person is a direct or indirect
     Subsidiary of another Person,  the Common Shares of which are and have been
     so registered,  "Principal Party" shall refer to such other Person; and (2)
     if the Common  Shares of such Person are not at such time and have not been
     continuously over the preceding 12 month period registered under Section 12
     of  the  Exchange  Act,  and  such  Person  is a  Subsidiary,  directly  or
     indirectly,  of more than one Person,  the Common  Shares of two or more of
     which are and have been so  registered,  "Principal  Party"  shall refer to
     whichever  of such  Persons is the issuer of the Common  Shares  having the
     greatest aggregate market value.

     (c) The  Company  covenants  and agrees  that it shall not  consummate  any
transaction  described  in clauses  (x),  (y),  or (z) of the first  sentence of
Section  13(a)  unless the  Principal  Party shall have a  sufficient  number of
authorized Common Shares that have not been issued (or reserved for issuance) or
that are held in its  treasury  to permit the  exercise in full of the Rights in
accordance  with this Section 13 and unless  prior  thereto the Company and such
Principal  Party  shall  have  executed  and  delivered  to the  Rights  Agent a
supplemental  agreement  providing for the terms set forth in paragraphs (a) and
(b) of this Section 13 and further  providing that, as soon as practicable after
the consummation of any Section 13(a) Event, the Principal Party will:

          (i)  prepare and file a  registration  statement  under the Act,  with
     respect to the Rights and the securities  purchasable  upon exercise of the
     Rights, on an appropriate form, and will use its best efforts to cause such
     registration statement to (A) become effective as soon as practicable after
     such  filing  and (B)  remain  effective  (with a  prospectus  at all times
     meeting the requirements of the Act) until the expiration date; and

                                       32.





          (ii) deliver to holders of the Rights historical  financial statements
     for the  Principal  Party  and each of its  Affiliates  that  comply in all
     respects with the  requirements for registration on Form 10 of the Exchange
     Act.

     (d) The Company  covenants  and agrees that it shall not, at any time after
the  Distribution  Date,  (i)  consolidate  with any other Person  (other than a
direct or indirect, wholly-owned Subsidiary of the Company in a transaction that
complies  with Section 11(o)  hereof),  (ii) merge with or into any other Person
(other than a direct or indirect,  wholly-owned  Subsidiary  of the Company in a
transaction that complies with Section 11(o) hereof), or (iii) sell or otherwise
transfer  (or  permit  one or more  of its  Subsidiaries  to  sell or  otherwise
transfer), in one or more transactions,  assets or earning power aggregating 50%
or more of the  assets or  earning  power of the  Company  and its  Subsidiaries
(taken as a whole) to any other Person or Persons (other than the Company or one
or more of its  direct or  indirect,  wholly-owned  Subsidiaries  in one or more
transactions  each of which  complies  with Section  11(o) hereof) if (x) at the
time of or immediately  after such transaction  there are any rights,  warrants,
instruments,  or securities  outstanding or any agreements or arrangements that,
as a  result  of the  consummation  of  such  transaction,  would  eliminate  or
substantially  diminish the benefits  intended to be afforded by the Rights,  or
(y) prior to,  simultaneously  with, or immediately after such transaction,  the
shareholders of the Person who constitutes,  or would constitute,  the Principal
Party shall have  received a  distribution  of Rights  previously  owned by such
Person or any of its Affiliates and Associates.

     (e) The provisions of this Section 13 shall  similarly  apply to successive
mergers or consolidations or sales or other transfers.

                                       33.





     Section 14. Fractional Rights and Fractional  Shares. (a) The Company shall
not be required to issue fractions of Rights or to distribute Right Certificates
that evidence fractional Rights. In lieu of such fractional Rights,  there shall
be paid to the registered holders of the Right Certificates with regard to which
such fractional  Rights would otherwise be issuable,  an amount in cash equal to
the same fraction of the current market value of a whole Right. For the purposes
of this Section  14(a),  the current  market value of a whole Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date on
which such  fractional  Rights would have been otherwise  issuable.  The closing
price for any day shall be the last sale price, regular way, or, in case no such
sale takes place on such day,  the average of the closing bid and asked  prices,
regular  way,  in  either  case  as  reported  in  the  principal   consolidated
transaction  reporting  system with respect to securities  listed or admitted to
trading  on the New York  Stock  Exchange  or, if the  Rights  are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated  transaction  reporting system with respect to securities listed on
the  principal  national  securities  exchange on which the Rights are listed or
admitted  to trading  or, if the Rights are not listed or admitted to trading on
any national  securities  exchange,  the last quoted price or, if not so quoted,
the average of the high bid and low asked prices in the over-the-counter market,
as reported  by NASDAQ or such other  system then in use or, if on any such date
the Rights are not quoted by any such  organization,  the average of the closing
bid and asked prices as furnished by a professional market maker making a market
in the Rights selected by the Board of Directors of the Company.  If on any such
date no such market  maker is making a market in the  Rights,  the fair value of
the Rights on such date as determined in good faith by the Board of Directors of
the Company shall be used.

                                       34.





     (b) The  Company  shall not be  required to issue  fractions  of  Preferred
Shares (other than fractions that are integral  multiples of one  one-thousandth
of a Preferred Share) upon exercise of the Rights or to distribute  certificates
that  evidence  fractional  Preferred  Shares  (other  than  fractions  that are
integral  multiples of one  one-thousandth of a Preferred  Share).  Fractions of
Preferred  Shares in integral  multiples  of one  one-thousandth  of a Preferred
Share may, at the election of the Company, be evidenced by depositary  receipts,
pursuant to an  appropriate  agreement  between  the  Company  and a  depositary
selected by it;  provided,  however,  that such agreement shall provide that the
holders of such depositary receipts shall have all the rights,  privileges,  and
preferences  to which they are entitled as  beneficial  owners of the  Preferred
Shares represented by such depositary receipts.  In lieu of fractional Preferred
Shares that are not  integral  multiples  of one  one-thousandth  of a Preferred
Share, the Company shall pay to the registered  holders of Right Certificates at
the time such Rights are exercised as herein provided an amount in cash equal to
the same fraction of the current  market value of one Preferred  Share.  For the
purposes of this Section 14(b),  the current  market value of a Preferred  Share
shall be the closing price of a Preferred  Share (as determined  pursuant to the
second  sentence of Section  11(d)(i)  hereof)  for the Trading Day  immediately
prior to the date of such exercise.

     (c) The holder of a Right by the acceptance of the Right  expressly  waives
his right to  receive  any  fractional  Rights  or any  fractional  shares  upon
exercise of a Right (except as provided above).

     Section  15.  Rights of  Action.  All  rights of action in  respect of this
Agreement,  excepting  the  rights of action  given to the  Rights  Agent  under
Section 18 hereof, are vested in the respective  registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders

                                       35.





of the Common Shares);  and any registered  holder of any Right Certificate (or,
prior to the Distribu tion Date, of the Common  Shares),  without the consent of
the Rights Agent or of the holder of any other Right  Certificate  (or, prior to
the Distribution Date, of the Common Shares), may, in his own behalf and for his
own benefit,  enforce,  and may  institute  and maintain  any suit,  action,  or
proceeding  against the Company to enforce,  or otherwise act in respect of, his
right to exercise the Rights  evidenced by such Right  Certificate in the manner
provided in such Right  Certificate and in this Agreement.  Without limiting the
foregoing or any remedies available to the holders of Rights, it is specifically
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Agreement and will be entitled to specific performance of
the  obligations  under,  and  injunctive  relief  against  actual or threatened
violations of the obligations of any Person subject to, this Agreement.

     Section  16.  Agreement  of Right  Holders.  Every  holder  of a Right,  by
accepting  the same,  consents  and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

     (a) prior to the Distribution Date, the Rights will be transferable only in
connection with the transfer of the Common Shares;

     (b) after the  Distribution  Date, the Right  Certificates are transferable
only on the registry books of the Rights Agent,  duly endorsed or accompanied by
a proper instrument of transfer;

     (c) the Company and the Rights Agent may deem and treat the person in whose
name the Right  Certificate (or, prior to the Distribution  Date, the associated
Common Shares  certificate)  is registered as the absolute  owner thereof and of
the Rights  evidenced  thereby  (notwithstanding  any  notations of ownership or
writing on the Right Certificates or the associated Common Shares

                                       36.





certificate  made by anyone other than the Company or the Rights  Agent) for all
purposes  whatsoever,  and neither  the  Company  nor the Rights  Agent shall be
affected by any notice to the contrary; and

     (d) notwithstanding anything in this Agreement to the contrary, neither the
Company nor the Rights  Agent shall have any  liability to any holder of a Right
or other Person as a result of its  inability to perform any of its  obligations
under this  Agreement by reason of any  preliminary  or permanent  injunction or
other order, decree or ruling issued by a court of competent  jurisdiction or by
a  governmental,  regulatory  or  administrative  agency or  commission,  or any
statute,  rule,  regulation  or executive  order  promulgated  or enacted by any
governmental authority, prohibiting or otherwise restraining performance of such
obligation; provided, however, the Company must use its best efforts to have any
such order, decree or ruling lifted or otherwise overturned as soon as possible.

     Section 17. Right Certificate  Holder Not Deemed a Shareholder.  No holder,
as such,  of any  Right  Certificate  shall be  entitled  to vote or to  receive
dividends or be deemed for any purpose the holder of the Preferred Shares or any
other securities of the Company that may at any time be issuable on the exercise
of the Rights represented thereby, nor shall anything contained herein or in any
Right  Certificate  be  construed  to  confer  upon  the  holder  of  any  Right
Certificate,  as such,  any of the rights of a shareholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
shareholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
shareholders  (except as provided in Section 25 hereof), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or Rights  evidenced by
such  Right  Certificate  shall  have  been  exercised  in  accordance  with the
provisions hereof.

                                       37.





     Section 18.  Concerning the Rights Agent.  The Company agrees to pay to the
Rights Agent reasonable  compensation for all services  rendered by it hereunder
and, from time to time, on demand of the Rights Agent,  its reasonable  expenses
and counsel  fees and other  disbursements  incurred in the  administration  and
execution  of this  Agreement  and the exercise  and  performance  of its duties
hereunder.  The Company  also agrees to  indemnify  the Rights Agent for, and to
hold it harmless  against,  any loss,  liability,  or expense,  incurred without
negligence,  bad faith,  or willful  misconduct on the part of the Rights Agent,
for  anything  done or  omitted  by the  Rights  Agent  in  connection  with the
acceptance  and  administration  of this  Agreement,  including  the  costs  and
expenses of defending against any claim of liability in the premises.

     The Rights Agent shall be protected and shall incur no liability for, or in
respect of any action taken,  suffered, or omitted by it in connection with, its
administration  of this  Agreement  in reliance  upon any Right  Certificate  or
certificate for the Preferred Shares or Common Shares or for other securities of
the  Company,   instrument  of  assignment  or  transfer,   power  of  attorney,
endorsement,   affidavit,  letter,  notice,  direction,   consent,  certificate,
statement,  or other  paper or  document  believed by it to be genuine and to be
signed, executed and, where necessary,  verified or acknowledged,  by the proper
person or  persons,  or  otherwise  upon the  advice of  counsel as set forth in
Section 20 hereof.

     Section 19. Merger or  Consolidation or Change of Name of Rights Agent. Any
corporation  into which the Rights  Agent or any  successor  Rights Agent may be
merged or with which it may be consolidated,  or any corporation  resulting from
any merger or  consolidation  to which the Rights Agent or any successor  Rights
Agent shall be a party, or any  corporation  succeeding to the stock transfer or
corporate trust powers of the Rights Agent or any successor

                                       38.





Rights Agent,  shall be the  successor to the Rights Agent under this  Agreement
without the  execution  or filing of any paper or any further act on the part of
any of the parties hereto; provided, that such corporation would be eligible for
appointment  as a  successor  Rights  Agent under the  provisions  of Section 21
hereof.  In case at the time such  successor  Rights Agent shall  succeed to the
agency created by this Agreement,  any of the Right Certificates shall have been
countersigned  but not delivered,  any such successor Rights Agent may adopt the
countersignature  of  the  predecessor  Rights  Agent  and  deliver  such  Right
Certificates  so  countersigned;  and in  case  at that  time  any of the  Right
Certificates shall not have been  countersigned,  any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor  Rights Agent;  and in all such cases such
Right  Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

     In case at any time the name of the Rights  Agent  shall be changed  and at
such time any of the Right  Certificates  shall have been  countersigned but not
delivered,  the Rights Agent may adopt the countersignature under its prior name
and deliver Right Certificates so countersigned; and in case at that time any of
the Right Certificates shall not have been  countersigned,  the Rights Agent may
countersign such Right  Certificates  either in its prior name or in its changed
name;  and in all such cases such Right  Certificates  shall have the full force
provided in the Right Certificates and in this Agreement.

     Section 20. Duties of Rights Agent.  The Rights Agent undertakes the duties
and  obligations  imposed  by  this  Agreement  upon  the  following  terms  and
conditions,  by all of which the Company and the holders of Right  Certificates,
by their acceptance thereof, shall be bound:

                                       39.





     (a) The  Rights  Agent may  consult  with legal  counsel  (who may be legal
counsel  for the  Company),  and the opinion of such  counsel  shall be full and
complete authorization and protection to the Rights Agent as to any action taken
or omitted by it in good faith and in accordance with such opinion.

     (b)  Whenever in the  performance  of its duties under this  Agreement  the
Rights Agent shall deem it  necessary  or  desirable  that any fact or matter be
proved or  established  by the Company  prior to taking or suffering  any action
hereunder,  such fact or matter  (unless  other  evidence in respect  thereof be
herein  specifically  prescribed)  may be deemed to be  conclusively  proved and
established by a certificate signed by any one of the Chairman of the Board, the
Chief Executive Officer, the President,  any Vice President,  the Treasurer,  or
the  Secretary  of the  Company  and  delivered  to the Rights  Agent;  and such
certificate shall be full authorization to the Rights Agent for any action taken
or  suffered  in good  faith by it under the  provisions  of this  Agreement  in
reliance upon such certificate.

     (c) The Rights Agent shall be liable hereunder to the Company and any other
Person only for its own negligence, bad faith, or willful misconduct.

     (d) The  Rights  Agent  shall not be liable  for or by reason of any of the
statements  of fact or  recitals  contained  in this  Agreement  or in the Right
Certificates (except its countersignature  thereof) or be required to verify the
same, but all such  statements and recitals are and shall be deemed to have been
made by the Company only.

     (e) The Rights  Agent shall not be under any  responsibility  in respect of
the validity of this Agreement or the execution and delivery  hereof (except the
due  execution  and  delivery  hereof by the Rights  Agent) or in respect of the
validity or execution of any Right Certificate (except its

                                       40.





countersignature  thereof);  nor shall it be  responsible  for any breach by the
Company of any covenant or condition contained in this Agreement or in any Right
Certificate; nor shall it be responsible for any change in the exercisability of
the Rights  (including the Rights becoming void pursuant to Section 7(e) hereof)
or any adjustment in the terms of the Rights  (including the manner,  method, or
amount  thereof)  provided  for  in  Section  3,  11,  13,  23,  or  24,  or the
ascertaining  of the  existence  of facts that would  require any such change or
adjustment  (except with  respect to the  exercise of Rights  evidenced by Right
Certificates  after actual  notice that such change or  adjustment is required);
nor  shall it by any act  hereunder  be  deemed  to make any  representation  or
warranty as to the  authorization  or reservation of any Preferred  Shares to be
issued pursuant to this Agreement or any Right  Certificate or as to whether any
Preferred Shares will, when issued, be validly authorized and issued, fully paid
and nonassessable.

     (f) The Company  agrees that it will  perform,  execute,  acknowledge,  and
deliver or cause to be performed, executed, acknowledged, and delivered all such
further  and other  acts,  instruments,  and  assurances  as may  reasonably  be
required by the Rights Agent for the carrying  out or  performing  by the Rights
Agent of the provisions of this Agreement.

     (g)  The  Rights  Agent  is  hereby   authorized  and  directed  to  accept
instructions  with respect to the  performance of its duties  hereunder from any
one of the Chairman of the Board,  the Chief Executive  Officer,  the President,
any Vice President, the Secretary, or the Treasurer of the Company, and to apply
to such officers for advice or instructions  in connection with its duties,  and
it shall not be liable for any action  taken or  suffered by it in good faith in
accordance  with  instructions  of any such  officer  or for any delay in acting
while waiting for those instructions.

                                       41.





     (h) The Rights Agent and any shareholder, director, officer, or employee of
the Rights Agent may buy, sell, or deal in any of the Rights or other securities
of the Company or become pecuniarily  interested in any transaction in which the
Company  may be  interested,  or  contract  with or lend money to the Company or
otherwise  act as fully and freely as though it were not Rights Agent under this
Agreement.  Nothing  herein  shall  preclude the Rights Agent from acting in any
other capacity for the Company or for any other legal entity.

     (i) The Rights  Agent may execute and  exercise any of the rights or powers
hereby vested in it or perform any duty hereunder either itself or by or through
its  attorneys  or  agents,  and the Rights  Agent  shall not be  answerable  or
accountable for any act, default,  neglect,  or misconduct of any such attorneys
or agents or for any loss to the Company  resulting from any such act,  default,
neglect, or misconduct,  provided reasonable care was exercised in the-selection
and continued employment thereof.

     Section  21.  Change of Rights  Agent.  The Rights  Agent or any  successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer agent
of the Common Shares or Preferred Shares by registered or certified mail, and to
the  registered  holders of the Right  Certificates  by  first-class  mail.  The
Company may remove the Rights Agent or any successor  Rights Agent upon 30 days'
notice in writing,  mailed to the Rights Agent or successor Rights Agent, as the
case may be, and to each transfer agent of the Common Shares or Preferred Shares
by  registered or certified  mail,  and to the  registered  holders of the Right
Certificates by first-class  mail,  postage  prepaid.  If the Rights Agent shall
resign or be removed or shall otherwise become incapable of acting,  the Company
shall appoint a successor to the Rights Agent. If the Company shall fail to make
such appointment within a period

                                       42.





of 30 days after giving  notice of such removal or after it has been notified in
writing of such  resignation  or incapacity  by the  resigning or  incapacitated
Rights  Agent or by the  holder of a Right  Certificate  (who  shall,  with such
notice,  submit his Right  Certificate for inspection by the Company),  then the
registered  holder of any Right  Certificate may apply to any court of competent
jurisdiction  for the  appointment of a new Rights Agent.  Any successor  Rights
Agent,  whether  appointed  by the  Company  or by  such  a  court,  shall  be a
corporation  organized and doing business under the laws of the United States or
of the State of New York (or of any other state of the United  States so long as
such  corporation is authorized to do business in the State of New York, in good
standing,  having an office in the State of New York,  which is authorized under
such laws to exercise corporate trust or stock transfer powers and is subject to
supervision or  examination  by federal or state  authority and which has at the
time of its  appointment  as Rights  Agent a combined  capital and surplus of at
least $25  million).  After  appointment,  the  successor  Rights Agent shall be
vested with the same powers,  rights,  duties, and responsibilities as if it had
been  originally  named as Rights  Agent  without  further act or deed;  but the
predecessor  Rights  Agent shall  deliver and transfer to the  successor  Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act, or deed necessary for the purpose. Not later
than the effective date of any such ap pointment,  the Company shall file notice
thereof in writing with the predecessor  Rights Agent and each transfer agent of
the Common Shares or Preferred  Shares,  and send, in accordance with Section 26
hereof,  a notice  thereof,  in  writing,  to the  registered  holders  of Right
Certificates.  Failure  to give any  notice  provided  for in this  Section  21,
however, or any defect therein, shall not affect the legality or validity of the
resignation  or removal of the Rights Agent or the  appointment of the successor
Rights Agent, as the case may be.

                                       43.





     Section 22. Issuance of New Right Certificates.  Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary,  the Company may,
at its option,  issue new Right  Certificates  evidencing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change in
the Purchase Price and the number or kind or class of shares or other securities
or property purchasable under the Right Certificates made in accordance with the
provisions of this Agreement.

     Section 23.  Redemption.  (a) The Board of Directors of the Company may, at
its option, at any time prior to the Close of Business on the tenth calendar day
following  the  Shares  Acquisition  Date (or,  if the Shares  Acquisition  Date
occurred  prior to the Record Date,  the Close of Business on the tenth calendar
day  following  the  Record  Date),  redeem  all but not less  than all the then
outstanding  Rights at a  redemption  price of $0.001 per  Right,  appropriately
adjusted to reflect any stock  split,  stock  dividend,  or similar  transaction
occurring  after the date hereof (such  redemption  price,  as  adjusted,  being
hereinafter referred to as the "Redemption Price");  provided,  however, that if
such  authorization  occurs on or after the date of a change  (resulting  from a
proxy solicitation) in a majority of the directors in office at the commencement
of  such  solicitation,  and  any  Person  who is or was a  participant  in such
solicitation  has stated (or if upon the  commencement of such  solicitation,  a
majority of the Board of Directors of the Company has  determined in good faith)
that such Person (or any of its Affiliates or  Associates)  has taken or intends
to take,  or may  consider  taking,  any action that would result in such Person
becoming an Acquiring  Person or that would cause the occurrence of a Triggering
Event (the  existence of the  circumstances  described in this  provision  being
referred to herein as an "Adverse Change of Control"), then the Rights may be so
redeemed only if there are Continuing Directors in office

                                       44.





and such  redemption is authorized by a majority of such  Continuing  Directors.
Notwithstanding  the foregoing,  the aggregate  Redemption  Price payable to any
holder of Rights upon the  redemption of all Rights held by such holder shall be
rounded to the nearest one cent ($0.01) (such that fractions of one cent ($0.01)
greater  than or equal to one-half of one cent  ($0.005)  shall be rounded up to
the next  highest cent and  fractions of one cent ($0.01) less than  one-half of
one cent ($0.005)  shall be rounded down to the next lowest  cent);  and further
provided  that the  aggregate  Redemption  Price payable to any holder of Rights
upon the  redemption of all Rights held by such Person shall in no event be less
than $0.01.  The  redemption of the Rights by the Board of Directors may be made
effective at such time, on such basis,  and with such conditions as the Board of
Directors in its sole discretion may establish.

     (b)  Immediately  upon the action of the Board of  Directors of the Company
effectively  ordering the redemption of the Rights  pursuant to paragraph (a) of
this  Section 23, and without  any  further  action and without any notice,  the
right to exercise the Rights will terminate and the only right thereafter of the
holders of Rights shall be to receive the  Redemption  Price.  The Company shall
promptly give public notice of any such redemption;  provided, however, that the
failure to give, or any defect in, any such notice shall not affect the validity
of such  redemption.  Within 10 days after such action of the Board of Directors
ordering  the  redemption  of the  Rights,  the  Company  shall mail a notice of
redemption  to all the  holders  of the then  outstanding  Rights at their  last
addresses as they appear upon the  registry  books of the Rights Agent or, prior
to the  Distribution  Date, on the registry  books of the transfer agent for the
Common Shares.  Any notice that is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice. Each such

                                       45.





notice  of  redemption  will  state  the  method  by which  the  payment  of the
Redemption Price will be made.  Neither the Company nor any of its Affiliates or
Associates may redeem,  acquire, or purchase for value any Rights at any time in
any  manner  other  than that  specifically  set forth in this  Section 23 or in
Section 24 hereof,  and other than in  connection  with the  purchase  of Common
Shares prior to the Distribution Date.

     Section 24. Exchange.

     (a) The Board of Directors  of the Company may, at its option,  at any time
after any Person becomes an Acquiring  Person,  exchange all or part of the then
outstanding  and  exercisable  Rights (which shall not include  Rights that have
become void pursuant to the provisions of Section 7(e) hereof) for Common Shares
at an exchange  ratio of one Common Share per Right,  appropriately  adjusted to
reflect any stock split, stock dividend,  or similar transaction occurring after
the date  hereof  (such  exchange  ratio  being  hereinafter  referred to as the
"Exchange Ratio").  Notwithstanding the foregoing,  the Board of Directors shall
not be  empowered  to effect such  exchange at any time after any Person  (other
than any Subsidiary of the Company,  any employee benefit plan of the Company or
any such Subsidiary,  or any entity holding Common Shares for or pursuant to the
terms of any such plan),  together with all  Affiliates  and  Associates of such
Person,  becomes the  Beneficial  Owner of 50% or more of the Common Shares then
outstanding.

     (b)  Immediately  upon the action of the Board of  Directors of the Company
ordering the exchange of any Rights pursuant to paragraph (a) of this Section 24
and  without any  further  action and without any notice,  the right to exercise
such Rights shall  terminate  and the only right  thereafter of a holder of such
Rights shall be to receive  that number of Common  Shares equal to the number of
such Rights held by such holder  multiplied by the Exchange  Ratio.  The Company
shall promptly

                                       46.





give public notice of any such exchange;  provided, however, that the failure to
give,  or any defect in,  such  notice  shall not  affect the  validity  of such
exchange.  The Company  promptly shall mail a notice of any such exchange to all
of the  holders of such Rights at their last  addresses  as they appear upon the
registry  books of the Rights  Agent.  Any  notice  that is mailed in the manner
herein  provided shall be deemed given,  whether or not the holder  receives the
notice. Each such notice of exchange will state the method by which the exchange
of the Common  Shares  for  Rights  will be  effected  and,  in the event of any
partial  exchange,  the number of Rights  that will be  exchanged.  Any  partial
exchange  shall be effected  pro rata based on the number of Rights  (other than
Rights that have become void pursuant to the  provisions of Section 7(e) hereof)
held by each holder of Rights.

(c) In the event that there shall not be sufficient Common Shares issued but not
outstanding  or  authorized  but  unissued  to permit any  exchange of Rights as
contemplated in accordance with this Section 24, the Company shall take all such
action as may be necessary to authorize  additional  Common  Shares for issuance
upon exchange of the Rights.  In the event the Company  shall,  after good faith
effort,  be unable to take all such action as may be necessary to authorize such
additional Common Shares,  the Company shall  substitute,  for each Common Share
that would otherwise be issuable upon exchange of a Right, a number of Preferred
Shares or fraction  thereof  such that the current per share market price of one
Preferred  Share  multiplied  by such number or fraction is equal to the current
per share  market  price of one Common  Share as of the date of issuance of such
Preferred Shares or fraction thereof.

(d) The Company shall not be required to issue  fractions of Common Shares or to
distribute  certificates that evidence fractional Common Shares. In lieu of such
fractional Common Shares, the Company shall pay to the registered holders of the
Right Certificates with regard to

                                       47.





which such  fractional  Common  Shares would  otherwise be issuable an amount in
cash equal to the same  fraction of the current  market  value of a whole Common
Share.  For the purposes of this  paragraph  (d), the current  market value of a
whole Common Share shall be the closing  price of a Common Share (as  determined
pursuant to the second sentence of Section  11(d)(i) hereof) for the Trading Day
immediately prior to the date of exchange pursuant to this Section 24.

     Section 25. Notice of Certain Events.

     (a) In case the Company  shall  propose (i) to pay any dividend  payable in
stock of any class to the holders of its  Preferred  Shares or to make any other
distribution  to the  holders  of its  Preferred  Shares  (other  than a regular
quarterly cash dividend),  (ii) to offer to the holders of its Preferred  Shares
rights or warrants to  subscribe  for or to purchase  any  additional  Preferred
Shares  or shares of stock of any  class or any  other  securities,  rights,  or
options,  (iii) to effect any  reclassification  of its Preferred  Shares (other
than a reclassification  involving only the subdivision of outstanding Preferred
Shares),  (iv) to effect any  consolidation or merger into or with, or to effect
any sale or other  transfer  (or to permit  one or more of its  Subsidiaries  to
effect any sale or other transfer), in one or more transactions,  of 50% or more
of the assets or earning power of the Company and its  Subsidiaries  (taken as a
whole) to, any other  Person,  (v) to effect the  liquidation,  dissolution,  or
winding up of the Company,  or (vi) to declare or pay any dividend on the Common
Shares  payable in Common  Shares or to effect a  subdivision,  combination,  or
consolidation  of the Common Shares (by  reclassification  or otherwise  than by
payment of dividends in Common  Shares),  then,  in each such case,  the Company
shall give to each registered holder of a Right Certificate,  in accordance with
Section 26 hereof,  a notice of such  proposed  action,  which shall specify the
record date for the purposes of such stock  dividend,  or distribution of rights
or warrants, or the date on

                                       48.





which such reclassification, consolidation, merger, sale, transfer, liquidation,
dissolution,  or  winding  up is to take  place  and the  date of  participation
therein by the holders of the Common Shares and/or Preferred Shares, if any such
date is to be fixed, and such notice shall be so given in the case of any action
covered by clause  (i) or (ii)  above at least 10 days prior to the record  date
for determining holders of the Preferred Shares for purposes of such action, and
in the case of any such other action,  at least 10 days prior to the date of the
taking of such  proposed  action  or the date of  participation  therein  by the
holders of the Common Shares and/or  Preferred  Shares,  whichever  shall be the
earlier.

     (b) In case the event set forth in Section  11(a)(ii)  hereof  shall occur,
then  (i) the  Company  shall  as soon as  practicable  thereafter  give to each
registered holder of a Right Certificate,  in accordance with Section 26 hereof,
a notice of the occurrence of such event, which notice shall describe such event
and the consequences of such event to holders of Rights under Section  11(a)(ii)
hereof,  and (ii) all  references  in the  preceding  Section 25(a) to Preferred
Shares shall be deemed to refer to Common Shares and/or,  if appropriate,  other
securities.

     (c) In case any  transaction  described in clauses (x),  (y), or (z) of the
first  sentence of Section  13(a) hereof shall occur,  then the Company shall as
soon  as  practicable  thereafter  give  to each  registered  holder  of a Right
Certificate, in accordance with Section 26 hereof, a notice of the occurrence of
such  transaction,   which  notice  shall  describe  such  transaction  and  the
consequences  of such  transaction  to holders  of Rights  under  Section  13(a)
hereof.

     Section 26. Notices.  Notices or demands authorized by this Agreement to be
given or made by the Rights Agent or by the holder of any Right  Certificate  to

supplement or amend this Agreement  without the approval of any holders of Right
Certificates  in order to cure any  ambiguity,  to  correct  or  supplement  any
provision  contained herein that may be defective or inconsistent with any other
provisions  herein,  or to make any other  provisions with respect to the Rights
that the  Company  may deem  necessary  or  desirable,  any such  supplement  or
amendment  to be  evidenced  by a writing  signed by the  Company and the Rights

                                       50.





of  Business  on the tenth  calendar  day  following  such  Record  Date),  this
Agreement  shall not be amended in any manner  that would  adversely  affect the
interests  of the  holders of Rights  (other  than  Rights that have become void
pursuant to Section 7(e) hereof);  and further provided,  that from and after an
Adverse  Change of  Control,  the Rights Plan shall not be amended in any manner
that would  adversely  affect the interests of the holders of Rights (other than

Continuing Directors in office and such amendment is authorized by a majority of
such Continuing  Directors.  Without limiting the foregoing,  the Company may at

largest percentage of the outstanding Common Shares then known by the Company to
be Beneficially  Owned by any Person (other than the Company,  any Subsidiary of
the Company,  any employee  benefit plan of the Company or any Subsidiary of the
Company, or any entity holding Common Shares for or pursuant to the terms of any
such plan) and (ii) 15%.

     Section 28. Successors.  All the covenants and provisions of this Agreement

holders of the Right  Certificates  (and,  prior to the  Distribution  Date, the
Common  Shares)  any legal or  equitable  right,  remedy,  or claim  under  this
Agreement; but this Agreement shall be for the sole and exclusive benefit of the
Company,  the Rights Agent, and the registered holders of the Right Certificates
(and, prior to the Distribution Date, the Common Shares).

                                    Exhibit A

                        RESOLUTION OF BOARD OF DIRECTORS
                       TO AMEND ARTICLES OF INCORPORATION
                   TO ESTABLISH A SERIES OF PREFERRED SHARES*


     RESOLVED, that pursuant to the authority granted to and vested in the Board
of Directors of the Company in accordance with the provisions of the Amended and
Restated  Articles of  Incorporation  of the  Company  and  Section  1522 of the
Pennsylvania Business Corporation Law, as amended, the Board of Directors hereby
adopts and  approves  an  amendment  to the  Amended  and  Restated  Articles of
Incorporation  of the Company,  as amended,  which creates out of the authorized
but  unissued  shares of  Preferred  Stock,  par value  $0.50 per share,  of the
Company a series of Preferred  Stock,  the designation and authorized  number of
shares of which, and the terms and relative rights,  preferences and limitations
of which, are as follows:

     Section 1.  Designation  and  Amount.  The shares of such  series  shall be
     designated as "Series A Junior Participating  Preferred Stock" (the "Series
     A  Preferred  Stock")  and the number of shares  constituting  the Series A
     Preferred Stock shall be 300,000. Such number of shares may be increased or
     decreased by resolution of the Board of  Directors;  provided,  (a) that no
     decrease shall reduce the number of shares of Series A Preferred Stock to a
     number less than the number of shares then  outstanding  plus the number of
     shares  reserved for issuance  upon the  exercise of  outstanding  options,
     rights,  or warrants or upon the conversion of any  outstanding  securities
     issued by the corporation  convertible  into Series A Preferred  Stock; and
     (b) no increase shall cause the aggregate number of all shares of Preferred
     Stock that the  corporation  is  authorized  to issue to be greater than is
     authorized by these Amended and Restated Articles of Incorporation.

     Section 2. Dividends and Distributions.

     (A) Subject to the rights of the holders of any shares of any other  series
     of Preferred  Stock of the corporation (or any similar stock) ranking prior
     and superior to the Series A Preferred Stock with respect to dividends, the
     holders of shares of Series A Preferred Stock, in preference to the holders
     of Common  Stock,  par value $0.50 per share (the "Common  Stock"),  of the
     corporation,  and of any other junior stock,  shall be entitled to receive,
     when,  as and if declared by the Board of  Directors  out of funds  legally
     available for the purpose, quarterly dividends payable in cash on the first
     day of March,  June,  September,  and December in each year (each such date
     being  referred  to  herein  as  a  "Quarterly   Dividend  Payment  Date"),
     commencing on the first Quarterly Dividend Payment

 *To be attached to a Statement with Respect to Shares or
to an Amendment to Articles of  Incorporation  filed with the Secretary of State
of Pennsylvania. 1.





     Date after the first issuance of a share or fraction of a share of Series A
     Preferred Stock, in an amount per share (rounded to the nearest cent) equal
     to the greater of (a) $1 or (b)  subject to the  provision  for  adjustment
     hereinafter  set forth,  1000 times the  aggregate  per share amount of all
     cash  dividends,  and 1000 times the aggregate per share amount (payable in
     kind) of all  non-cash  dividends  or  other  distributions,  other  than a
     dividend  payable  in  shares  of  Common  Stock  or a  subdivision  of the
     outstanding  shares of Common  Stock (by  reclassification  or  otherwise),
     declared on the Common  Stock  since the  immediately  preceding  Quarterly
     Dividend  Payment  Date or, with  respect to the first  Quarterly  Dividend
     Payment Date,  since the first issuance of any share or fraction of a share
     of Series A Preferred Stock. In the event the corporation shall at any time
     declare or pay any dividend on the Common Stock payable in shares of Common
     Stock,  or effect a subdivision  or  combination  or  consolidation  of the
     outstanding shares of Common Stock (by  reclassification  or otherwise than
     by  payment  of a  dividend  in shares of Common  Stock)  into a greater or
     lesser number of shares of Common Stock,  then in each such case the amount
     to which  holders  of shares  of Series A  Preferred  Stock  were  entitled
     immediately prior to such event under clause (b) of the preceding  sentence
     shall be adjusted by multiplying  such amount by a fraction,  the numerator
     of which is the number of shares of Common  Stock  outstanding  immediately
     after  such event and the  denominator  of which is the number of shares of
     Common Stock that were outstanding immediately prior to such event.

          (B) The  corporation  shall declare a dividend or  distribution on the
     Series A  Preferred  Stock as  provided in  paragraph  (A) of this  Section
     immediately  after it  declares a dividend  or  distribution  on the Common
     Stock (other than a dividend  payable in shares of Common Stock);  provided
     that, in the event no dividend or distribution  shall have been declared on
     the Common Stock during the period between any Quarterly  Dividend  Payment
     Date and the next subsequent Quarterly Dividend Payment Date, a dividend of
     $1 per share on the Series A Preferred Stock shall  nevertheless be payable
     on such subsequent Quarterly Dividend Payment Date.

          (C) Dividends  shall begin to accrue and be cumulative on  outstanding
     shares of Series A Preferred Stock from the Quarterly Dividend Payment Date
     next  preceding the date of issue of such shares,  unless the date of issue
     of such shares is prior to the record date for the first Quarterly Dividend
     Payment Date, in which case  dividends on such shares shall begin to accrue
     from the date of issue of such  shares,  or  unless  the date of issue is a
     Quarterly  Dividend Payment Date or is a date after the record date for the
     determination  of holders of shares of Series A Preferred Stock entitled to
     receive a quarterly  dividend and before such  Quarterly  Dividend  Payment
     Date, in either of which events such dividends shall begin to accrue and be
     cumulative from such Quarterly  Dividend  Payment Date.  Accrued but unpaid
     dividends shall not bear interest. Dividends paid on the shares of Series

                                       2.





     A Preferred Stock in an amount less than the total amount of such dividends
     at the time accrued and payable on such shares shall be allocated  pro rata
     on a share-by-  share basis among all such shares at the time  outstanding.
     The  Board of  Directors  may fix a record  date for the  determination  of
     holders of shares of Series A Preferred  Stock entitled to receive  payment
     of a dividend or distribution declared thereon,  which record date shall be
     not more than 60 days prior to the date fixed for the payment thereof.

     Section 3. Voting Rights. The holders of shares of Series A Preferred Stock
     shall have the following voting rights:

          (A) Subject to the provision  for  adjustment  hereinafter  set forth,
     each share of Series A Preferred  Stock shall entitle the holder thereof to
     1000 votes on all matters  submitted to a vote of the  shareholders  of the
     corporation.  In the event the corporation shall at any time declare or pay
     any  dividend on the Common  Stock  payable in shares of Common  Stock,  or
     effect a subdivision  or combination or  consolidation  of the  outstanding
     shares of Common Stock (by reclassification or otherwise than by payment of
     a dividend in shares of Common  Stock)  into a greater or lesser  number of
     shares of  Common  Stock,  then in each  such case the  number of votes per
     share to which holders of shares of Series A Preferred  Stock were entitled
     immediately  prior to such event  shall be  adjusted  by  multiplying  such
     number by a  fraction,  the  numerator  of which is the number of shares of
     Common Stock  outstanding  immediately after such event and the denominator
     of which is the  number of shares of  Common  Stock  that were  outstanding
     immediately prior to such event.

          (B) Except as otherwise provided herein or in any other Statement with
     Respect  to Shares or other  amendment  of the  Articles  of  Incorporation
     creating a series of Preferred  Stock or any similar stock,  or by law, the
     holders of shares of Series A Preferred  Stock and the holders of shares of
     Common Stock and any other capital stock of the corporation  having general
     voting rights shall vote together as one class on all matters  submitted to
     a vote of shareholders of the corporation.

          (C)  Except as set forth  herein,  or as  otherwise  provided  by law,
     holders of Series A Preferred Stock shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with  holders of Common  Stock as set forth  herein) for taking any
     corporate action.

     Section 4. Certain Restrictions.

          (A) Whenever  quarterly  dividends or other dividends or distributions
     payable on the Series A  Preferred  Stock as  provided  in Section 2 are in
     arrears,  thereafter  and  until  all  accrued  and  unpaid  dividends  and
     distributions, whether or

                                       3.





     not declared,  on shares of Series A Preferred Stock outstanding shall have
     been paid in full, the corporation shall not:

          (i) declare or pay dividends, or make any other distributions,  on any
     shares of stock ranking junior (either as to dividends or upon liquidation,
     dissolution, or winding up) to the Series A Preferred Stock;

          (ii) declare or pay dividends, or make any other distributions, on any
     shares  of  stock  ranking  on a parity  (either  as to  dividends  or upon
     liquidation, dissolution, or winding up) with the Series A Preferred Stock,
     except  dividends paid ratably on the Series A Preferred Stock and all such
     parity stock on which  dividends are payable or in arrears in proportion to
     the  total  amounts  to  which  the  holders  of all such  shares  are then
     entitled;

          (iii) redeem or purchase or otherwise acquire for consideration shares
     of any stock ranking  junior  (either as to dividends or upon  liquidation,
     dis solution, or winding up) to the Series A Preferred Stock, provided that
     the  corporation  may at any time redeem,  purchase,  or otherwise  acquire
     shares of any such junior  stock in exchange for shares of any stock of the
     corporation  ranking  junior  (either as to dividends or upon  dissolution,
     liquidation, or winding up) to the Series A Preferred Stock; or

          (iv) redeem or purchase or  otherwise  acquire for  consideration  any
     shares of Series A  Preferred  Stock,  or any shares of stock  ranking on a
     parity  with the Series A  Preferred  Stock,  except in  accordance  with a
     purchase  offer made in writing or by  publication  (as  determined  by the
     Board of  Directors)  to all  holders of such shares upon such terms as the
     Board of Directors,  after  consideration of the respective annual dividend
     rates and other relative  rights and  preferences of the respective  series
     and  classes,  shall  determine  in good  faith  will  result  in fair  and
     equitable treatment among the respective series or classes.

          (B) The corporation shall not permit any subsidiary of the corporation
     to purchase or otherwise  acquire for  consideration any shares of stock of
     the corporation  unless the corporation  could, under paragraph (A) of this
     Section 4,  purchase or  otherwise  acquire such shares at such time and in
     such manner.

     Section  5.  Reacquired  Shares.  Any  shares of Series A  Preferred  Stock
     purchased or otherwise acquired by the corporation in any manner whatsoever
     shall be retired and canceled promptly after the acquisition  thereof.  All
     such shares shall upon their  cancellation  become  authorized but unissued
     shares of  Preferred  Stock and may be  reissued as part of a new series of
     Preferred Stock subject to the conditions and  restrictions on issuance set
     forth herein, in the Articles of Incorporation, or in

                                       4.





     any other Articles of Amendment  creating a series of Preferred  Stock, par
     value $0.50 per share,  or any similar  stock or as  otherwise  required by
     law.

     Section 6. Liquidation,  Dissolution,  or Winding Up. Upon any liquidation,
     dissolution,  or winding up of the  corporation,  no distribution  shall be
     made (1) to the  holder of shares of stock  ranking  junior  (either  as to
     dividends or upon liquidation,  dissolution, or winding up) to the Series A
     Preferred  Stock  unless the holders of shares of Series A Preferred  Stock
     outstanding  shall have received out of the assets of the Company available
     for distribution to its shareholders after payment or provision for payment
     of any securities  ranking senior to the Series A Preferred Stock, for each
     share of Series A Preferred  Stock,  subject to adjustment  as  hereinafter
     provided, (A) $1000.00 plus an amount equal to accrued and unpaid dividends
     and  distributions  thereon,  whether or not declared,  to the date of such
     payment or, (B) if greater than the amount  specified  in clause  (1)(A) of
     this  sentence,  an amount equal to 1000 times the  aggregate  amount to be
     distributed  per  share to  holders  of  Common  Stock,  as the same may be
     adjusted  as  herein  provided,  or (2) to the  holders  of shares of stock
     ranking  on  a  parity  (either  as  to  dividends  or  upon   liquidation,
     dissolution,  or winding  up) with the  Series A  Preferred  Stock,  unless
     simultaneously  therewith  distributions  are made  ratably on the Series A
     Preferred  Stock  and all such  parity  stock in  proportion  to the  total
     amounts to which the  holders of all such  shares  are  entitled  upon such
     liquidation, dissolution, or winding up. In the event the corporation shall
     at any time  declare or pay any  dividend  on the Common  Stock  payable in
     shares  of  Common  Stock,  or  effect  a  subdivision  or  combination  or
     consolidation   of   the   outstanding   shares   of   Common   Stock   (by
     reclassification  or  otherwise  than by payment of a dividend in shares of
     Common  Stock) into a greater or lesser  number of shares of Common  Stock,
     then in each such case the  aggregate  amount to which holders of shares of
     Series A  Preferred  Stock were  entitled  immediately  prior to such event
     under  the  provision  in clause  (1) of the  preceding  sentence  shall be
     adjusted by multiplying such amount by a fraction the numerator of which is
     the number of shares of Common  Stock  outstanding  immediately  after such
     event and the  denominator of which is the number of shares of Common Stock
     that were outstanding immediately prior to such event.

     Section 7. Consolidation,  Merger, etc. In case the corporation shall enter
     into any consolidation,  merger, combination, or other transaction in which
     the shares of Common Stock are exchanged for or changed into other stock or
     securities,  cash,  and/or any other  property,  then in any such case each
     share of  Series A  Preferred  Stock  shall at the same  time be  similarly
     exchanged or changed into an amount per share, subject to the provision for
     adjustment  hereinafter set forth, equal to 1000 times the aggregate amount
     of stock, securities, cash, and/or any other property (payable in kind), as
     the case may be,  into  which or for which  each  share of Common  Stock is
     changed or exchanged. In the event the corporation shall at any

                                       5.





     time declare or pay any  dividend on the Common Stock  payable in shares of
     Common Stock,  or effect a subdivision or combination or  consolidation  of
     the outstanding  shares of Common Stock (by  reclassification  or otherwise
     than by payment of a dividend in shares of Common  Stock) into a greater or
     lesser number of shares of Common Stock,  then in each such case the amount
     set forth in the preceding  sentence with respect to the exchange or change
     of shares of Series A Preferred Stock shall be adjusted by multiplying such
     amount by a  fraction,  the  numerator  of which is the number of shares of
     Common Stock  outstanding im mediately after such event and the denominator
     of which is the  number of shares of  Common  Stock  that were  outstanding
     immediately prior to such event.

     Section 8. No Redemption.  The shares of Series A Preferred Stock shall not
     be redeemable.

     Section 9. Rank. The Series A Preferred  Stock shall rank,  with respect to
     the payment of  dividends  and the  distribution  of assets,  junior to all
     other series of the corporation's Preferred Stock.

     Section 10.  Amendment.  The Articles of  Incorporation  of the corporation
     shall not be amended in any manner  that would  materially  alter or change
     the powers,  preferences, or special rights of the Series A Preferred Stock
     so as to affect them adversely  without the affirmative vote of the holders
     of at least  two-thirds  of the  outstanding  shares of Series A  Preferred
     Stock, voting together as a single class.


                                       6.

                                    Exhibit C

         UNDER  CERTAIN  CIRCUMSTANCES,  AS SET  FORTH IN THE  RIGHTS  AGREEMENT
         REFERRED TO BELOW,  RIGHTS  OWNED BY OR  TRANSFERRED  TO ANY PERSON WHO
         BECOMES AN ACQUIRING  PERSON (AS DEFINED IN THE RIGHTS  AGREEMENT)  AND
         CERTAIN  TRANSFEREES  THEREOF  WILL  BECOME  NULL  AND VOID AND WILL NO
         LONGER BE TRANSFERABLE.


                          SUMMARY OF RIGHTS TO PURCHASE
                            SHARES OF PREFERRED STOCK

     On August 22, 1996 (the "Rights Dividend  Declaration  Date"), the Board of
Directors of Mylan Laboratories Inc. (the  "Corporation")  adopted a Shareholder
Rights Plan and declared that a dividend of one share purchase  right  ("Right")
be distributed on each  outstanding  share of Common Stock,  par value $0.50 per
share ("Common Stock"), to shareholders of record as of the close of business on
September 5, 1996 (the "Record Date"). Each Right entitles the registered holder
to  purchase  from the  Corporation  one  one-thousandth  of a share of Series A
Preferred Stock, par value $0.50 per share ("Preferred  Stock"),  or, in certain
circumstances,  shares of Common Stock,  other securities,  and/or cash or other
property,  at a Purchase  Price of $90 per share of  Preferred  Stock (or,  when
applicable,  Common Stock, securities,  cash, and/or other property), subject to
adjustment.  The complete  terms and conditions of the Rights are set forth in a
Rights  Agreement dated as of August 22, 1996 (the "Rights  Agreement")  between
the  Corporation  and American Stock Transfer & Trust Company,  as Rights Agent.
All shares of Common Stock  outstanding on the Record Date will receive  Rights.
In addition,  all shares of Common Stock issued prior to the  Distribution  Date
will be issued with Rights.  All  certificates for Common Stock issued after the
Record  Date  and  prior  to  the  Distribution   Date  will  contain  a  legend
incorporating the Rights Agreement by reference.

     Initially,  the  Rights  will  attach to the  outstanding  shares of Common
Stock, and no separate Right  Certificates will be distributed.  The Rights will
detach  from  the  outstanding   shares  of  Common  Stock  and  separate  Right
Certificates  will  be  issued  when  there  is a  Distribution  Date.  Until  a
Distribution  Date occurs,  the Rights will be evidenced by the  certificate for
the  shares of  Common  Stock  with a copy of this  Summary  of Rights  attached
thereto,  the  Rights  will  transfer  with (and only with) the shares of Common
Stock to which such Rights are attached, and the transfer of any certificate for
Common Stock (with or without this Summary of Rights attached thereto) will also
constitute  the  transfer of the Rights  attached to the shares of Common  Stock
represented by such certificate.

     A  "Distribution  Date" will occur on (i) the tenth day  following a public
announcement  that a person has  become an  Acquiring  Person  (the date of such
public  announcement being the "Shares  Acquisition  Date"), or (ii) if earlier,
the tenth  business day (or such later date as may be determined by the Board of
Directors  prior  to such  time  as any  person  becomes  an  Acquiring  Person)
following the  commencement  or  announcement of a tender or exchange offer that
would result in a person or group of affiliated or associated  persons  becoming
the Beneficial Owner of 15% or more of the outstanding shares of Common Stock.


                                       1.





     An  "Acquiring  Person" is a person or group of  affiliated  or  associated
persons that Beneficially  Owns 15% or more of the outstanding  shares of Common
Stock but does not include (1) the Corporation,  its subsidiaries,  any employee
benefit  plan  of the  Corporation  or any of its  Subsidiaries,  or any  entity
holding  shares of Common Stock  pursuant to the terms of any such plan; (2) any
person  or  group  that  becomes  the  Beneficial  Owner  of 15% or  more of the
outstanding  shares of Common  Stock  solely as a result of the  acquisition  of
Common Stock by the Corporation, unless such person or group thereafter acquires
additional  shares of Common  Stock;  or (3) subject to certain  conditions  set
forth in the Rights  Agreement,  a person  that  otherwise  would have become an
Acquiring Person as a result of an inadvertent acquisition of 15% or more of the
outstanding shares of Common Stock.

     The Rights are not exercisable  until the Distribution Date and will expire
at the close of business on  September  5, 2006 (the "Final  Expiration  Date"),
unless the Final  Expiration  Date is  extended or unless the Rights are earlier
redeemed or exchanged by the Corporation, in each case, as described below.

     As  soon  as  practicable  after  the  Distribution  Date,  separate  Right
Certificates  will be mailed to the holders of record of Common  Stock as of the
Distribution Date, and, thereafter,  the Right Certificates alone will represent
the Rights.

     The Purchase  Price  payable upon  exercise of the Rights and the number of
shares of Preferred Stock (and the amount of other  securities  and/or property,
if any) issuable upon exercise of the Rights are subject to adjustment from time
to time to prevent  dilution in the event that (i) there is a stock dividend on,
or a subdivision,  combination,  or  reclassification of the Preferred Stock, or
(ii) the holders of Preferred Stock are granted certain  options,  warrants,  or
rights to subscribe  for or purchase  shares of Preferred  Stock (or  equivalent
Preferred  Stock) or securities  convertible into Preferred Stock (or securities
convertible  into equivalent  Preferred  Stock) at a price less than the current
market price of Preferred  Stock,  or (iii) any  evidences  of  indebtedness  or
assets  (other than regular  quarterly  cash  dividends or dividends  payable in
shares of Preferred  Stock) or any  subscription  rights or warrants (other than
rights,  options,  or  warrants  of the type  referred to in clause (ii) of this
paragraph) are distributed to the holders of Preferred Stock.

     Subject to certain  exceptions  as set forth in the  Rights  Agreement,  no
adjustment  in  the  Purchase  Price  will  be  required  until  the  cumulative
adjustments amount to 1% of the Purchase Price.

     The number of outstanding Rights and the number of one one-thousandths of a
share of Preferred  Stock  issuable upon exercise of each Right are also subject
to  adjustment  in the  event of a stock  split of the  Common  Stock or a stock
dividend  on the shares of Common  Stock  payable  in shares of Common  Stock or
subdivisions,  consolidations,  or  combinations  of the shares of Common  Stock
occurring, in any such case, prior to the Distribution Date.

     No  fractional  shares of Preferred  Stock (other than  fractions  that are
integral multiples of one  one-thousandths of a share of Preferred Stock, which,
at the election of the  Corporation,  may be evidenced by  depository  receipts)
will be issued  upon  exercise  of the  Rights,  but,  in lieu  thereof,  a cash
adjustment  will be paid to the  holder  of the  exercised  Rights  based on the
market price of the  Preferred  Stock on the last trading date prior to the date
of exercise.

                                       2.





     Shares of Preferred Stock  purchasable upon exercise of the Rights will not
be redeemable. The dividend,  liquidation, and voting rights, and non-redemption
features  of the  Preferred  Stock  are  designed  so that  the  value  of a one
one-thousandth  interest in a share of Preferred Stock purchasable upon exercise
of each Right should  approximate  the value of one share of Common Stock.  Each
whole  share  of  Preferred  Stock  will be  entitled  to  receive  a  quarterly
preferential  dividend  equal to the  greater  of (a) $1 or (b) 1000  times  the
dividend  declared with respect to each share of Common  Stock.  In the event of
liquidation, the holders of each whole share of Preferred Stock will be entitled
to receive a preferential  liquidation payment equal to the greater of (a) $1000
or (b) 1000  times the  payment  made per share of Common  Stock.  Each share of
Preferred Stock will have 1000 votes,  voting together with the shares of Common
Stock. Finally, in the event of any merger, consolidation,  or other transaction
in which shares of Common Stock are exchanged for or changed into other stock or
securities,  cash, and/or other property,  each share of Preferred Stock will be
entitled to receive 1000 times the amount  received  per share of Common  Stock.
These  rights  and   preferences   are  protected  by  customary   anti-dilution
provisions.

     Once a person has become an  Acquiring  Person,  all  Rights  that are,  or
(under  certain   circumstances   specified  in  the  Rights   Agreement)  were,
Beneficially Owned by an Acquiring Person will be null and void.

     In the event that any person becomes an Acquiring Person,  proper provision
shall be made so that each holder of a Right  (other than a Right that is or was
Beneficially Owned by an Acquiring Person that has become null and void pursuant
to the  terms of the  Rights  Agreement),  shall  thereafter  have the  right to
receive  upon  exercise of such Right that number of shares of Common Stock (or,
in certain  circumstances,  Preferred Stock,  other securities,  property and/or
cash) having a value equal to two times the then-current Purchase Price.

     In the event that, at any time after a person becomes an Acquiring  Person,
(i) the  Corporation is acquired in a merger or other business  combination,  or
(ii) 50% or more of the  assets  or  earning  power of the  Corporation  and its
Subsidiaries  (taken  as a  whole)  is sold  or  otherwise  transferred,  proper
provision  will be made so that each holder of a Right  (other than a Right that
is or was  Beneficially  Owned by an  Acquiring  Person that has become null and
void pursuant to the terms of the Rights  Agreement)  shall  thereafter have the
right to receive  upon  exercise of such Right,  in lieu of shares of  Preferred
Stock, shares of common stock of the acquiror then having a current market value
equal to two times the  then-current  Purchase Price.  The events referred to in
the  preceding  paragraph  and in  clauses  (i) and (ii) of this  paragraph  are
hereinafter referred to as "Triggering Events."

     At any time  prior to the  Close of  Business  on the  tenth  calendar  day
following  the  Shares  Acquisition  Date (or,  if the Shares  Acquisition  Date
occurred  prior to the Record Date,  the Close of Business on the tenth calendar
day following such Record Date),  the Board of Directors of the  Corporation may
redeem  the  Rights in whole,  but not in part,  at a price of $0.001 per Right,
subject to adjustment (the "Redemption Price") provided,  however,  that if such
authorization  occurs on or after the date of a change  (resulting  from a proxy
solicitation)  in a majority of the directors in office at the  commencement  of
such  solicitation,  and  any  Person  who  is or  was  a  participant  in  such
solicitation  has stated (or if upon the  commencement of such  solicitation,  a
majority of the Board of Directors of the Company has  determined in good faith)
that such Person (or any of its Affiliates or  Associates)  has taken or intends
to take, or may consider taking, any

                                       3.





action that would  result in such Person  becoming an  Acquiring  Person or that
would  cause  the  occurrence  of a  Triggering  Event  (the  existence  of  the
circumstances  described  in this  provision  being  referred  to  herein  as an
"Adverse  Change of Control"),  then the Rights may be so redeemed only if there
are  Continuing  Directors  in office and such  redemption  is  authorized  by a
majority of such Continuing Directors.  The redemption of the Rights may be made
effective at such time, on such basis,  and with such conditions as the Board of
Directors in its sole discretion may establish.  Immediately upon any redemption
of the Rights,  the right to exercise  the Rights  will  terminate  and the only
right of the holders of Rights will be to receive the Redemption Price.

At any time after any person becomes an Acquiring Person,  and prior to the time
any person (other than the Corporation,  any of its  Subsidiaries,  any employee
benefit  plan of the  Corporation  or any of its  Subsidiaries,  and any  entity
holding  shares of Common Stock  pursuant to the terms of any such plan) becomes
the Beneficial  Owner of 50% or more of the outstanding  shares of Common Stock,
the  Corporation  may,  at the option and  election  of the Board of  Directors,
exchange  shares  of  Common  Stock  (or in  certain  circumstances,  shares  of
Preferred  Stock) for all or any part of the  then-outstanding  and  unexercised
Rights  (other than Rights that are or were  Beneficially  Owned by an Acquiring
Person  that have  become  null and void  pursuant  to the  terms of the  Rights
Agreement)  at an  exchange  rate of one  share of Common  Stock (or in  certain
circumstances,  one  one-thousandth  of a share of  Preferred  Stock) per Right,
appropriately adjusted to reflect any stock dividend, stock split, reverse stock
split,  or  other  similar  transaction  occurring  after  the  Rights  Dividend
Declaration Date.

The  terms  of the  Rights  may be  amended  by the  Board of  Directors  of the
Corporation  without the consent of the holders of the Rights,  except that from
and after the Close of Business on the tenth  calendar day  following the Shares
Acquisition  Date (or,  if the Shares  Acquisition  Date  occurred  prior to the
Record  Date,  the Close of Business on the tenth  calendar day  following  such
Record Date) no such amendment may adversely affect the interests of the holders
of the Rights  (other  than  Rights  that are or were  Beneficially  Owned by an
Acquiring  Person that have  become  null and void  pursuant to the terms of the
Rights  Agreement) and provided,  however,  that if such amendment  occurs on or
after an Adverse Change of Control,  then the Rights Plan may be amended only if
there are  Continuing  Directors in office and such amendment is authorized by a
majority of such Continuing Directors.

Until a Right is exercised,  the holder thereof, as such, will have no rights as
a shareholder of the Corporation,  including,  without limitation,  the right to
vote or to receive dividends.

     This Right  Certificate  is subject  to all of the  terms,  provisions  and
 conditions of the Rights Agreement, which terms, provisions and conditions are
