Item 1.  Description of Securities to be Registered

                  On  April  30,  1998,   the  Board  of  Directors  of  Quantum
                  Corporation  (the  "Company")   declared  a  dividend  of  one
                  Preferred   Share   Purchase   Right  (a  "Right")   for  each
                  outstanding share of Common Stock (the "Common Shares") of the
                  Company.  The  dividend  is  payable  on  August  5, 1998 (the
                  "Record Date") to the  stockholders  of record as of the close
                  of business on that date, and is further  payable with respect
                  to each Common Share that shall become outstanding between the
                  Record Date and the earlier of the  Distribution  Date and the
                  Expiration  Date (as such terms are  defined  herein),  and in
                  certain  circumstances after the Distribution Date. Each Right
                  entitles the  registered  holder to purchase  from the Company
                  one one-thousandth of a share of Series A Junior Participating
                  Preferred  Stock,  par  value  $.01 per  share  (a  "Preferred
                  Share"),   of  the  Company,  at  a  price  of  $115  per  one
                  one-thousandth  of a Preferred  Share (the "Purchase  Price"),
                  subject to adjustment. The description and terms of the Rights
                  are set forth in a  Preferred  Shares  Rights  Agreement  (the
                  "Rights  Agreement")  between the Company and Harris Trust and
                  Savings Bank, as Rights Agent (the "Rights Agent").

                  The following is a general  description only and is subject to
                  the detailed terms and conditions of the Rights  Agreement.  A
                  copy of the  Rights  Agreement,  including  the Form of Rights
                  Certificate   and   Summary  of  Rights  to  be   provided  to
                  stockholders  of the  Company,  is  attached as Exhibit 4.1 to
                  this  Registration  Statement  and is  incorporated  herein by
                  reference.

                  Distribution and Transfer of Rights; Rights Certificate

                  The Board of  Directors  has  declared a dividend of one Right
                  for each Common Share. Prior to the Distribution Date referred
                  to below,  the Rights will be  evidenced by and trade with the
                  certificates  for the  Common  Stock.  After the  Distribution
                  Date,  the  Company  will  mail  Rights  certificates  to  the
                  Company's stockholders and the Rights will become transferable
                  apart from the Common Stock.

                  Distribution Date

                  Rights  will   separate  from  the  Common  Stock  and  become
                  exercisable following (a) the tenth day (or such later date as
                  may be  determined  by a majority  of the Board of  Directors)
                  after a person or group acquires  beneficial  ownership of 20%
                  or  more  of the  Company's  Common  Stock  or (b)  the  tenth
                  business  day (or such  later date as may be  determined  by a
                  majority  of the Board of  Directors)  after a person or group
                  announces  a tender or exchange  offer,  the  consummation  of
                  which would result in ownership by a person or group of 20% or
                  more of the Company's Common Stock.



<PAGE>

                  Preferred Stock Purchasable Upon Exercise of Rights

                  After the  Distribution  Date,  each  Right will  entitle  the
                  holder to purchase for $115,  a fraction of a Preferred  Share
                  with  economic  terms  similar  to  that of one  share  of the
                  Company's Common Stock.

                  Flip-In

                  If an acquiror (an "Acquiring  Person") obtains 20% or more of
                  the Company's Common Stock, then each Right (other than Rights
                  owned by an Acquiring  Person or its affiliates)  will entitle
                  the holder  thereof to  purchase,  for the Exercise  Price,  a
                  number of shares of the  Company's  Common Stock having a then
                  current market value of twice the Exercise Price.

                  Flip-Over

                  If,  after  an  Acquiring  Person  obtains  20% or more of the
                  Company's  Common Stock,  (a) the Company  merges into another
                  entity, (b) an acquiring entity merges into the Company or (c)
                  the  Company  sells more than 50% of the  Company's  assets or
                  earning power,  then each Right (other than Rights owned by an
                  Acquiring  Person or its  affiliates)  will entitle the holder
                  thereof  to  purchase,  for the  Exercise  Price,  a number of
                  shares  of  Common  Stock  of  the  Person   engaging  in  the
                  transaction  having a then  current  market value of twice the
                  Exercise  Price  (unless  the  transaction  satisfies  certain
                  conditions  and is  consummated  with a  Person  who  acquired
                  shares pursuant to a Permitted Offer, in which case the Rights
                  will expire).

                  Exchange Provision

                  At any time after the date an Acquiring  Person obtains 20% or
                  more  of  the   Company's   Common  Stock  and  prior  to  the
                  acquisition by the Acquiring  Person of 50% of the outstanding
                  Common  Stock,  a majority  of the Board of  Directors  of the
                  Company may  exchange  the Rights  (other than Rights owned by
                  the Acquiring Person or its affiliates),  in whole or in part,
                  for shares of Common Stock of the Company at an exchange ratio
                  of  one  share  of  Common   Stock  per  Right   (subject   to
                  adjustment).

                  Redemption of the Rights

                  Rights will be redeemable  at the  Company's  option for $0.01
                  per  Right at any time on or prior to the  tenth  day (or such
                  later date as may be  determined by a majority of the Board of
                  Directors)  after  public   announcement  that  a  Person  has
                  acquired beneficial  ownership of 20% or more of the Company's
                  Common Stock.



<PAGE>

                  Expiration of the Rights

                  The Rights  expire on the earliest of (a) August 4, 2008,  (b)
                  exchange or  redemption of the Rights as described  above,  or
                  (c)  consummation  of a merger or  consolidation  resulting in
                  expiration of the Rights as described above.

                  Amendment of Terms of Rights

                  The  terms  of the  Rights  and the  Rights  Agreement  may be
                  amended  in any  respect  without  the  consent  of the Rights
                  holders on or prior to the Distribution Date. Thereafter,  the
                  terms of the Rights and the  Rights  Agreement  may be amended
                  without the consent of the Rights holders in order to cure any
                  ambiguities  or to make changes which do not adversely  affect
                  the  interests  of Rights  holders  (other than the  Acquiring
                  Person).

                  Voting Rights

                  Rights will not have any voting rights.

                  Anti-Dilution Provisions

                  Rights   will   have  the   benefit   of   certain   customary
                  anti-dilution provisions.

                  Taxes

                  The Rights  distribution  should not be  taxable  for  federal
                  income tax purposes. However, following an event which renders
                  the  Rights  exercisable  or upon  redemption  of the  Rights,
                  stockholders may recognize taxable income.

                                RIGHTS AGREEMENT


         Agreement,  dated as of July 28, 1998, between Quantum  Corporation,  a
Delaware  corporation  (the  "Company"),  and Harris Trust and Savings Bank (the
"Rights Agent").

         On April 30, 1998 (the "Rights Dividend  Declaration  Date"), the Board
of Directors of the Company  authorized and declared a dividend of one Preferred
Share Purchase Right (a "Right") for each Common Share (as hereinafter  defined)
of the Company outstanding as of the Close of Business (as hereinafter  defined)
on August 5, 1998 (the  "Record  Date"),  each Right  representing  the right to
purchase  one  one-thousandth  of a  share  of  Series  A  Junior  Participating
Preferred  Stock (as such number may be adjusted  pursuant to the  provisions of
this Agreement),  having the rights, preferences and privileges set forth in the
form of Certificate of  Designations  of Rights,  Preferences  and Privileges of
Series A Junior Participating Preferred Stock attached hereto as Exhibit A, upon
the terms and subject to the conditions herein set forth, and further authorized
and directed the issuance of one Right (as such number may be adjusted  pursuant
to the  provisions  of this  Agreement)  with  respect to each Common Share that
shall  become  outstanding  between  the  Record  Date  and the  earlier  of the
Distribution  Date  and the  Expiration  Date  (as such  terms  are  hereinafter
defined), and in certain circumstances after the Distribution Date.

         NOW,  THEREFORE,  in  consideration  of the  promises  and  the  mutual
agreements herein set forth, the parties 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 who or which,
together  with  all  Affiliates  and  Associates  of such  Person,  shall be the
Beneficial Owner of 20% or more of the Common Shares then outstanding, but shall
not include the Company,  any Subsidiary of the Company or 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. Notwithstanding the
foregoing,  no Person shall be deemed to be 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 to 20% or more of the Common  Shares of the  Company  then
outstanding;  provided,  however,  that if a Person shall become the  Beneficial
Owner of 20% 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 (other than pursuant to a dividend or  distribution  paid or made by
the Company on the  outstanding  Common Shares in Common Shares or pursuant to a
split or subdivision of the outstanding  Common Shares),  then such Person shall
be deemed to be an Acquiring Person unless upon becoming the Beneficial Owner of
such additional  Common Shares of the Company such Person does not  beneficially
own  20%  or  more  of  the  Common  Shares  of the  Company  then  outstanding.
Notwithstanding  the  foregoing,   (i)  if  the  Company's  Board  of  Directors
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
(including,  without  limitation,  because (A) such  Person was unaware  that it
beneficially  owned a percentage of the Common Shares that would otherwise cause
such Person to be an  "Acquiring  Person," as defined  pursuant to the foregoing
provisions of this  paragraph (a), or (B) such Person was aware of the extent of
the  Common  Shares it  beneficially  owned but had no actual  knowledge  of the
consequences of such beneficial  ownership under this Agreement) and without any
intention of changing or influencing control of the Company,  and if such Person
divested or 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 or to have  become  an  "Acquiring  Person"  for any
purposes of this  Agreement;  and (ii) if, as of the date hereof,  any Person is
the  Beneficial  Owner of [20%] or more of the Common Shares  outstanding,  such
Person shall not be or become an "Acquiring  Person," as defined pursuant to the
foregoing  provisions of this paragraph (a),  unless and until such time as such
Person shall become the Beneficial Owner of additional Common Shares (other than
pursuant  to a  dividend  or  distribution  paid or made by the  Company  on the
outstanding Common Shares in Common Shares or pursuant to a split or subdivision
of the outstanding Common Shares), unless, upon becoming the Beneficial Owner of
such additional  Common Shares,  such Person is not then the Beneficial Owner of
20% or more of the Common Shares then outstanding.

Regulations under the Exchange Act, as in effect on the date of this Agreement.

                  (d) A Person  shall be deemed  the  "Beneficial  Owner" of and
shall be deemed to "beneficially own" any securities:

                             (i)  which  such  Person  or any of  such  Person's

         (or any comparable or successor law or regulation);

                            (ii)  which  such  Person  or any of  such  Person's

         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

         such Person or any of such Person's Affiliates or Associates until such
         tendered  securities  are accepted  for  purchase or  exchange,  or (2)
         securities which a Person or any of such

         Directors of the Company prior to there being an Acquiring  Person;  or

         indirectly, by any other Person (or any Affiliate or Associate thereof)
         with which such Person or any of such Person's Affiliates or Associates
         has any  agreement,  arrangement  or  understanding,  whether or not in
         writing (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; provided,  however, that in

Trading Days  immediately  prior to such date, and for purposes of  computations

of any  Security  on any date  shall be  deemed to be the  average  of the daily
closing prices per share of such Security for the ten (10)  consecutive  Trading

following the  announcement  by the issuer of such Security of (i) a dividend or

convertible   into  such  shares  or  (ii)  any   subdivision,   combination  or

thirty (30)  Trading Day or ten (10) Trading Day period,  after the  ex-dividend

shares on such date as determined in good faith by the Board of Directors of the
Company  shall be used.  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 this Section 1(k), as appropriately  adjusted to reflect

of Rights per Common Share has been made pursuant to Section 11 hereof,  then at
the time of distribu tion of the Rights Certificates, the Company shall make the
necessary and appropriate rounding adjustments (in accordance with Section 14(a)

Distribution   Date,  the  Rights  will  be  evidenced  solely  by  such  Rights
Certificates  and may be transferred by the transfer of the Rights  Certificates
as permitted  hereby,  separately  and apart from any transfer of Common Shares,
and the  holders of such  Rights  Certificates  as listed in the  records of the
Company or any transfer  agent or  registrar  for the Rights shall be the record
holders thereof.

                  (b) On the Record Date or as soon as  practicable  thereafter,
the  Company  will  send a  copy  of  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's transfer agent and registrar.  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 the Summary of Rights. Until the Distribution Date
(or, if  earlier,  the  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,  shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.

                  (c) Unless the Board of Directors by resolution  adopted at or
before the time of the issuance of any Common Shares  specifies to the contrary,
Rights shall be issued in respect of all Common Shares that are issued after the
Record Date but prior to the earlier of the Distribution  Date or the Expiration
Date or, in certain  circumstances  provided  in  Section  22 hereof,  after the
Distribution  Date.  Certificates  representing such Common Shares shall also be
deemed to be certificates for Rights, and shall bear the following legend:

           WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH PERSON OR BY
           ANY SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID.

With respect to such  certificates  containing the foregoing  legend,  until the
earlier of (i) the  Distribution  Date or (ii) the  Expiration  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.

                  (d) 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 which are no longer outstanding.

         Section 4.  Form of Rights Certificates.

                  (a) The  Rights  Certificates  (and the forms of  election  to
purchase  Common Shares and of assignment to be printed on the reverse  thereof)
shall be  substantially  in the form of 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 or a national  market system,  on which
the Rights may from time to time be listed or included,  or to conform to usage.
Subject  to the  provisions  of Section  11 and  Section  22 hereof,  the Rights
Certificates,  whenever distributed, shall be dated as of the Record Date (or in
the case of Rights  issued with respect to Common  Shares  issued by the Company
after the Record Date, as of the date of issuance of such Common  Shares) and on
their  face  shall  entitle  the  holders  thereof to  purchase  such  number of
one-thousandths  of a Preferred Share as shall be set forth therein at the price
set forth therein (such  exercise  price per one  one-thousandth  of a Preferred
Share being  hereinafter  referred to as the "Exercise  Price" and the aggregate
Exercise Price of all Preferred Shares issuable upon exercise of one Right being
hereinafter  referred to as the "Total Exercise Price"), but the number and type
of securities purchasable upon the exercise of each Right and the Exercise Price
shall be subject to adjustment as provided herein.

                  (b) Any Rights  Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring
Person or any Associate or Affiliate of an Acquiring  Person,  (ii) a transferee
of an Acquiring  Person (or of any such  Associate or  Affiliate)  who becomes a
transferee  after the Acquiring  Person becomes such or (iii) a transferee of an
Acquiring  Person  (or of  any  such  Associate  or  Affiliate)  who  becomes  a
transferee prior to or concurrently  with the Acquiring Person becoming such and
receives  such  Rights  pursuant  to either (A) a transfer  (whether  or not for
consideration)  from the Acquiring Person to holders of equity interests in such
Acquiring  Person  or to any  Person  with whom such  Acquiring  Person  has any
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights or (B) a transfer  which a majority of the  Company's  Board of Directors
has determined is part of a plan, arrangement or understanding which has as a


                                  -9-

<PAGE>



primary  purpose or effect  avoidance  of Section  7(e)  hereof,  and any Rights
Certificate  issued  pursuant to Section 6 or Section 11 hereof  upon  transfer,
exchange,  replacement or adjustment of any other Rights Certificate referred to
in this sentence, shall contain (to the extent feasible) the following legend:

         THE RIGHTS  REPRESENTED BY THIS RIGHTS  CERTIFICATE  ARE OR
         WERE  BENEFICIALLY  OWNED BY A PERSON  WHO WAS OR BECAME AN
         ACQUIRING  PERSON  OR  AN  AFFILIATE  OR  ASSOCIATE  OF  AN
         ACQUIRING  PERSON (AS SUCH TERMS ARE  DEFINED IN THE RIGHTS
         AGREEMENT).  ACCORDINGLY,  THIS RIGHTS  CERTIFICATE AND THE
         RIGHTS  REPRESENTED  HEREBY MAY BECOME NULL AND VOID IN THE
         CIRCUMSTANCES  SPECIFIED  IN  SECTION  7(e)  OF THE  RIGHTS
         AGREEMENT.

         Section 5.  Countersignature and Registration.

                  (a) The Rights Certificates shall be executed on behalf of the
Company by its Chairman of the Board,  its Chief  Executive  Officer,  its Chief
Financial  Officer,  its President or any Vice President,  either manually or by
facsimile  signature,  and by the  Secretary  or an  Assistant  Secretary of the
Company,  either  manually or by  facsimile  signature,  and shall have  affixed
thereto  the  Company's  seal  (if  any)  or a  facsimile  thereof.  The  Rights
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 Rights  Certificates  shall cease to be
such  officer of the Company  before  countersignature  by the Rights  Agent and
issuance and delivery by the Company,  such Rights  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  Rights
Certificates  on behalf of the Company had not ceased to be such  officer of the
Company;  and any Rights  Certificate  may be signed on behalf of the Company by
any person who, at the actual date of the execution of such Rights  Certificate,
shall be a proper  officer  of the  Company  to sign  such  Rights  Certificate,
although at the date of the  execution of this Rights  Agreement any such person
was not such an officer.

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

         Section 6.  Transfer,  Split Up,  Combination  and  Exchange  of Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates.

                  (a)  Subject to the  provisions  of Sections  7(e),  14 and 24
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the Expiration Date, any Rights Certificate
or Rights  Certificates may be transferred,  split up, combined or exchanged for
another  Rights  Certificate  or Rights  Certificates,  entitling the registered
holder to purchase a like number of  one-thousandths  of a Preferred  Share (or,
following a Triggering Event, other securities, cash


                                      -10-

<PAGE>



or other  assets,  as the  case  may be) as the  Rights  Certificate  or  Rights
Certificates  surrendered then entitled such holder to purchase.  Any registered
holder  desiring  to  transfer,   split  up,  combine  or  exchange  any  Rights
Certificate or Rights  Certificates shall make such request in writing delivered
to the  Rights  Agent,  and shall  surrender  the Rights  Certificate  or Rights
Certificates to be transferred, split up, combined or exchanged at the office of
the Rights Agent  designated for such purpose.  Neither the Rights Agent nor the
Company  shall be  obligated to take any action  whatsoever  with respect to the
transfer of any such surrendered  Rights Certificate until the registered holder
shall  have  completed  and  signed  the  certificate  contained  in the form of
assignment  on the  reverse  side of such  Rights  Certificate  and  shall  have
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.  Thereupon the Rights Agent shall, subject to Sections
7(e), 14 and 24 hereof, countersign and deliver to the person entitled thereto a
Rights Certificate or Rights 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 Rights Certificates.

                  (b)  Upon  receipt  by the  Company  and the  Rights  Agent of
evidence  reasonably  satisfactory  to them of the loss,  theft,  destruction or
mutilation of a Rights 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 Rights  Certificate if mutilated,  the Company will make and
deliver a new Rights  Certificate of like tenor to the Rights Agent for delivery
to the  registered  holder in lieu of the Rights  Certificate  so lost,  stolen,
destroyed or mutilated.

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

                  (a) Subject to Sections 7(e),  23(b),  23(c) and 24(b) hereof,
the  registered  holder  of any  Rights  Certificate  may  exercise  the  Rights
evidenced  thereby (except as otherwise  provided herein) in whole or in part at
any time after the  Distribution  Date and prior to the Close of Business on the
Expiration  Date by  surrender  of the  Rights  Certificate,  with  the  form of
election to purchase on the reverse side thereof  duly  executed,  to the Rights
Agent at the office of the Rights Agent  designated  for such purpose,  together
with payment of the Exercise Price for each  one-thousandth of a Preferred Share
(or, following a Triggering Event, other securities, cash or other assets as the
case may be) as to which the Rights are exercised.

                  (b) The Exercise Price for each  one-thousandth of a Preferred
Share  issuable  pursuant  to the  exercise of a Right  shall  initially  be One
Hundred Fifteen Dollars ($115), shall be subject to adjustment from time to time
as provided in Sections 11 and 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  Rights   Certificate   representing
exercisable  Rights,  with the  form of  election  to  purchase  duly  executed,
accompanied by payment of the Exercise  Price for the number of  one-thousandths
of a Preferred Share (or, following a Triggering Event,  other securities,  cash
or other


                                      -11-

<PAGE>



assets as the case may be) to be purchased and an amount equal to any applicable
transfer  tax  required to be paid by the holder of such Rights  Certificate  in
accordance with Section 9(e) hereof, the Rights Agent shall,  subject to Section
20(k) hereof,  thereupon promptly (i) (A) requisition from any transfer agent of
the  Preferred  Shares (or make  available,  if the Rights Agent is the transfer
agent for the Preferred  Shares) a certificate or certificates for the number of
one-thousandths  of a Preferred Share (or,  following a Triggering Event,  other
securities,  cash or other  assets as the case may be) to be  purchased  and the
Company hereby irrevocably authorizes its transfer agent to comply with all such
requests or (B) if the Company shall have elected to deposit the total number of
one-thousandths  of a Preferred Share (or,  following a Triggering Event,  other
securities,  cash or other assets as the case may be) issuable  upon exercise of
the Rights  hereunder with a depositary  agent,  requisition from the depositary
agent  depositary  receipts  representing  such number of  one-thousandths  of a
Preferred Share (or,  following a Triggering Event,  other  securities,  cash or
other  assets  as  the  case  may  be) as are to be  purchased  (in  which  case
certificates for the Preferred Shares (or,  following a Triggering Event,  other
securities,  cash or  other  assets  as the  case  may be)  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
Rights  Certificate,  registered  in such name or names as may be  designated by
such holder and (iv) when appropriate,  after receipt thereof, deliver such cash
to or upon the order of the registered  holder of such Rights  Certificate.  The
payment of the Exercise Price (as such amount may be reduced (including to zero)
pursuant to Section  11(a)(iii)  hereof) and an amount  equal to any  applicable
transfer  tax  required to be paid by the holder of such Rights  Certificate  in
accordance  with Section 9(e) hereof,  may be made in cash or by certified  bank
check, cashier's check or bank draft payable to the order of the Company. In the
event that the Company is obligated  to issue  securities  of the Company  other
than Preferred  Shares,  pay cash and/or  distribute other property  pursuant to
Section 11(a) hereof,  the Company will make all arrangements  necessary so that
such other securities, cash and/or other property are available for distribution
by the Rights Agent, if and when appropriate.

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

                  (e)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  from and after the first occurrence of a Triggering Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring  Person,  (ii) a  transferee  of an  Acquiring  Person (or of any such
Associate or  Affiliate)  who becomes a transferee  after the  Acquiring  Person
becomes such (a  "Post-Event  Transferee"),  (iii) a transferee  of an Acquiring
Person (or of any such Associate or Affiliate) who becomes a transferee prior to
or concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer  (whether or not for  consideration)  from the
Acquiring  Person to holders of equity  interests in such Acquiring Person or to
any  Person  with  whom  the  Acquiring  Person  has any  continuing  agreement,
arrangement or understanding regarding the transferred Rights


                                      -12-

<PAGE>



or (B) a transfer  which a majority  of the  Company's  Board of  Directors  has
determined  is part of a  plan,  arrangement  or  understanding  which  has as a
primary  purpose or effect the  avoidance  of this  Section  7(e) (a  "Pre-Event
Transferee") or (iv) any subsequent transferee receiving transferred Rights from
a Post-Event  Transferee or a Pre-Event  Transferee,  either directly or through
one or more  intermediate  transferees,  shall  become null and void without any
further  action and no holder of such  Rights  shall have any rights  whatsoever
with respect to such Rights,  whether under any  provision of this  Agreement or
otherwise.  The  Company  shall use all  reasonable  efforts to ensure  that the
provisions of this Section 7(e) and Section 4(b) hereof are complied  with,  but
shall have no  liability  to any holder of Rights  Certificates  or to any other
Person as a result of its failure to make any determinations  with respect to an
Acquiring  Person or any of such Acquiring  Person's  Affiliates,  Associates or
transferees hereunder.

                  (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,  in addition to having  complied with the  requirements of Section
7(a) above, have (i) completed and signed the certificate  contained in the form
of election to purchase set forth on the reverse side of the Rights  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 Rights  Certificates.  All
Rights 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 canceled form,
or, if surrendered  to the Rights Agent,  shall be canceled by it, and no Rights
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
any of the provisions of this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement,  and the Rights Agent shall so cancel and
retire,  any Rights  Certificate  purchased or acquired by the Company otherwise
than upon the  exercise  thereof.  The Rights  Agent shall  deliver all canceled
Rights  Certificates  to the Company,  or shall,  at the written  request of the
Company,  destroy  such  canceled  Rights  Certificates,  and in such case shall
deliver a certificate of destruction thereof to the Company.

         Section 9.  Reservation and Availability of Preferred Shares.

                  (a) The Company covenants and agrees that it will use its best
efforts to cause to be reserved and kept  available  out of its  authorized  and
unissued  Preferred Shares not reserved for another purpose (and,  following the
occurrence of a Triggering  Event,  out of its  authorized  and unissued  Common
Shares and/or other securities),  the number of Preferred Shares (and, following
the occurrence of the Triggering  Event,  Common Shares and/or other securities)
that  will be  sufficient  to permit  the  exercise  in full of all  outstanding
Rights.

                  (b) If the Company shall  hereafter  list any of its Preferred
Shares on a national securities  exchange,  then so long as the Preferred Shares
(and, following the occurrence of a Triggering


                                      -13-

<PAGE>



Event,  Common Shares and/or other  securities)  issuable and  deliverable  upon
exercise of the Rights may be listed on such exchange, the Company shall use its
best efforts to cause, from and after such time as the Rights become exercisable
(but only to the extent  that it is  reasonably  likely  that the Rights will be
exercised),  all shares reserved for such issuance to be listed on such exchange
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 a
Triggering Event in which the  consideration to be delivered by the Company upon
exercise of the Rights is described in Section  11(a)(ii) or Section  11(a)(iii)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a registration  statement  under the Securities 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
Securities  Act) until the earlier of (A) the date as of which the Rights are no
longer  exercisable  for such  securities  and (B) the date of expiration of the
Rights. The Company may temporarily  suspend,  for a period not to exceed ninety
(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,  and notify
the Rights Agent,  that the  exercisability  of the Rights has been  temporarily
suspended, as well as a public announcement and notification to the Rights Agent
at such time as the  suspension  is no longer in effect.  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. Notwithstanding any provision of this Agreement to
the contrary,  the Rights shall not be exercisable in any  jurisdiction,  unless
the requisite qualification in such jurisdiction shall have been obtained, or an
exemption therefrom shall be available,  and until a registration  statement has
been declared effective.

                  (d) The  Company  covenants  and agrees  that it will take all
such action as may be  necessary to ensure that all  Preferred  Shares (or other
securities of the Company)  delivered upon exercise of Rights shall, at the time
of delivery of the certificates  for such securities  (subject to payment of the
Exercise  Price),  be duly and validly  authorized and issued and fully paid and
nonassessable shares.

                  (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
which may be payable in respect of the  original  issuance  or  delivery  of the
Rights  Certificates  or of any  Preferred  Shares (or other  securities  of the
Company)  upon the  exercise  of Rights.  The  Company  shall not,  however,  be
required to pay any transfer tax which may be payable in respect of any transfer
or delivery of Rights  Certificates  to a person other than,  or the issuance or
delivery of  certificates  or depositary  receipts for the Preferred  Shares (or
other  securities  of the Company) in a name other than that of, the  registered
holder of the Rights  Certificate  evidencing Rights surrendered for exercise or
to issue or to deliver any  certificates  or  depositary  receipts for Preferred
Shares (or other  securities  of the  Company)  upon the  exercise of any Rights
until any such tax shall  have  been  paid  (any such tax being  payable  by the
holder of such Rights


                                      -14-

<PAGE>



Certificate  at the time of surrender) or until it has been  established  to the
Company's satisfaction that no such tax is due.

         Section 10. Record Date.  Each Person in whose name any certificate for
a number of  one-thousandths  of a Preferred  Share (or other  securities of the
Company) is issued upon the  exercise of Rights shall for all purposes be deemed
to have become the holder of record of Preferred  Shares (or other securities of
the Company)  represented  thereby on, and such certificate  shall be dated, the
date  upon  which  the  Rights  Certificate  evidencing  such  Rights  was  duly
surrendered  and payment of the Total  Exercise  Price with respect to which the
Rights  have  been  exercised  (and any  applicable  transfer  taxes)  was made;
provided, however, that if the date of such surrender and payment is a date upon
which the 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 transfer books of the
Company are open.  Prior to the exercise of the Rights  evidenced  thereby,  the
holder of a Rights  Certificate  shall not be entitled to any rights of a holder
of Preferred  Shares (or other  securities  of the Company) for which the Rights
shall be  exercisable,  including,  without  limitation,  the right 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 Exercise Price, Number of Shares or Number of
Rights.  The  Exercise  Price,  the number and kind of shares or other  property
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)   Anything  in  this   Agreement   to  the   contrary
notwithstanding,  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 (by reverse stock split or otherwise) 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),  then, in each such event,
except as otherwise provided in this Section 11 and Section 7(e) hereof: (1) the
Exercise  Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price  thereafter  shall equal the result obtained
by dividing the  Exercise  Price in effect  immediately  prior to such time by a
fraction (the "Adjustment Fraction"),  the numerator of which shall be the total
number  of  Preferred  Shares  (or  shares  of  capital  stock  issued  in  such
reclassification of the Preferred Shares) outstanding immediately following such
time and the denominator of which shall be the total number of Preferred  Shares
outstanding immediately prior to such time; provided,  however, that in no event
shall the  consideration  to be paid upon the exercise of one Right be less than
the aggregate  par value of the shares of capital stock of the Company  issuable
upon  exercise  of such  Right;  and  (2) the  number  of  one-thousandths  of a
Preferred  Share  (or  share of such  other  capital  stock)  issuable  upon the
exercise of each Right shall equal the number of  one-thousandths of a Preferred
Share (or share of such other capital  stock) as was issuable upon exercise of a
Right  immediately  prior to the  occurrence  of the event  described in clauses
(A)-(D)  of  this  Section  11(a)(i),  multiplied  by the  Adjustment  Fraction;
provided,  however,  that,  no such  adjustment  shall be made  pursuant to this
Section


                                      -15-

<PAGE>



11(a)(i) to the extent that there  shall have  simultaneously  occurred an event
described in clause (A), (B), (C) or (D) of Section  11(n) with a  proportionate
adjustment  being  made   thereunder.   Each  Common  Share  that  shall  become
outstanding  after an adjustment has been made pursuant to this Section 11(a)(i)
shall have  associated  with the number of Rights,  exercisable  at the Exercise
Price and for the number of  one-thousandths  of a Preferred Share (or shares of
such other capital stock) as one Common Share has associated with it immediately
following the adjustment made pursuant to this Section 11(a)(i).

                           (ii) Subject to Section 24 of this Agreement,  in the
event a Triggering  Event shall have  occurred,  then  promptly  following  such
Triggering  Event each holder of a Right,  except as  provided  in Section  7(e)
hereof, shall thereafter have the right to receive for each Right, upon exercise
thereof in accordance  with the terms of this Agreement and payment of the Total
Exercise Price in effect  immediately  prior to the occurrence of the Triggering
Event, in lieu of a number of  one-thousandths of a Preferred Share, such number
of  Common  Shares  of the  Company  as  shall  equal  the  result  obtained  by
multiplying the Exercise Price in effect  immediately prior to the occurrence of
the Triggering Event by the number of  one-thousandths  of a Preferred Share for
which  a  Right  was  exercisable  (or  would  have  been   exercisable  if  the
Distribution  Date had occurred)  immediately prior to the first occurrence of a
Triggering  Event,  and  dividing  that  product by 50% of the Current Per Share
Market  Price for  Common  Shares on the date of  occurrence  of the  Triggering
Event;  provided,  however,  that the  Exercise  Price and the  number of Common
Shares of the Company so receivable upon exercise of a Right shall be subject to
further  adjustment as  appropriate  in accordance  with Section 11(e) hereof to
reflect  any events  occurring  in respect of the Common  Shares of the  Company
after the occurrence of the Triggering Event.

                           (iii) In lieu of issuing  Common Shares in accordance
with Section 11(a)(ii)  hereof,  the Company may, if a majority of the Company's
Board of Directors  determines  that such action is necessary or appropriate and
not contrary to the  interest of holders of Rights  (and,  in the event that the
number of Common Shares which are  authorized by the  Company's  Certificate  of
Incorporation  but not  outstanding  or reserved for issuance for purposes other
than upon  exercise of the Rights are not suffi cient to permit the  exercise in
full of the Rights,  or if any necessary  regulatory  approval for such issuance
has not been  obtained by the Company,  the Company  shall):  (A)  determine the
excess of (1) the value of the Common  Shares  issuable  upon the  exercise of a
Right (the  "Current  Value")  over (2) the  Exercise  Price (such  excess,  the
"Spread")  and (B) with  respect  to each  Right,  make  adequate  provision  to
substitute for such Common Shares,  upon exercise of the Rights, (1) cash, (2) a
reduction in the Exercise  Price,  (3) other  equity  securities  of the Company
(including,  without  limitation,  shares or units of  shares  of any  series of
preferred  stock which a majority of the Company's Board of Directors has deemed
to have the same  value as  Common  Shares  (such  shares  or units of shares of
preferred  stock are herein called "Common Stock  Equivalents")),  except to the
extent that the Company has not obtained any necessary stockholder or regulatory
approval for such issuance,  (4) debt  securities of the Company,  except to the
extent that the Company has not obtained any necessary stockholder or regulatory
approval  for such  issuance,  (5) other  assets or (6) any  combination  of the
foregoing,  having an  aggregate  value equal to the Current  Value,  where such
aggregate  value has been  determined  by a majority of the  Company's  Board of
Directors based upon the advice of a nationally  recognized  investment  banking
firm selected by a majority of the Company's Board of Directors; provided,


                                      -16-

<PAGE>


however,  if the Company shall not have made adequate provision to deliver value
pursuant to clause (B) above within thirty (30) days  following the later of (x)
the  first  occurrence  of a  Triggering  Event  and (y) the date on  which  the
Company's  right of  redemption  pursuant to Section 23(a) expires (the later of
(x) and (y) being referred to herein as the "Section  11(a)(ii)  Trigger Date"),
then the Company shall be obligated to deliver,  upon the surrender for exercise
of a Right and without  requiring  payment of the Exercise Price,  Common Shares
(to the  extent  available),  except  to the  extent  that the  Company  has not
obtained any necessary stockholder or regulatory approval for such issuance, and
then, if necessary, cash, which shares and/or cash have an aggregate value equal
to the Spread. If a majority of the Company's Board of Directors shall determine
in good faith that it is likely that sufficient  additional  Common Shares could
be  authorized  for  issuance  upon  exercise  in full of the Rights or that any
necessary  regulatory  approval for such issuance  will be obtained,  the thirty
(30) day period set forth above may be extended to the extent necessary, but not
more than ninety (90) days after the Section  11(a)(ii)  Trigger  Date, in order
that the Company may seek  stockholder  approval for the  authorization  of such
additional  shares or take  action  to obtain  such  regulatory  approval  (such
period, as it may be extended,  the "Substitution  Period").  To the extent that
the Company  determines  that some  action  need be taken  pursuant to the first
and/or  second  sentences  of this  Section  11(a)(iii),  the  Company (x) shall
provide,  subject to Section 7(e) hereof, that such action shall apply uniformly
to all outstanding  Rights and (y) may suspend the  exercisability of the Rights
until  the  expiration  of  the  Substitution   Period  in  order  to  seek  any
authorization  of additional  shares,  to take any action to obtain any required
regulatory  approval and/or to decide the appropriate form of distribution to be
made pursuant to such first sentence and to determine the value thereof.  In the
event of 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. For purposes of this Section 11(a)(iii),  the value of the Common Shares
shall be the Current Per Share Market Price of the Common  Shares on the Section
11(a)(ii)  Trigger  Date and the value of any Common Stock  Equivalent  shall be
deemed to have the same value as the Common Shares on such date.

                  (b) In case the Company  shall,  at any time after the date of
this  Agreement,  fix a record  date for the  issuance  of  rights,  options  or
warrants to all holders of Preferred Shares entitling such holders (for a period
expiring  within  forty-five  (45)  calendar  days  after such  record  date) to
subscribe for or purchase  Preferred  Shares or Equivalent  Shares or securities
convertible into Preferred Shares or Equivalent  Shares at a price per share (or
having a conversion  price per share, if a security  convertible  into Preferred
Shares or  Equivalent  Shares) less than the then Current Per Share Market Price
of the Preferred Shares or Equivalent  Shares on such record date, then, in each
such case,  the  Exercise  Price to be in effect after such record date shall be
determined by multiplying the Exercise Price in effect immediately prior to such
record  date by a  fraction,  the  numerator  of which  shall be the  number  of
Preferred Shares and Equivalent Shares (if any) outstanding on such record date,
plus the number of Preferred  Shares or Equivalent  Shares,  as the case may be,
which the aggregate  offering  price of the total number of Preferred  Shares or
Equivalent  Shares,  as the case may be, to be  offered  or issued  (and/or  the
aggregate initial  conversion price of the convertible  securities to be offered
or issued) would purchase at such current market price,  and the  denominator of
which shall be the number of  Preferred  Shares and  Equivalent  Shares (if any)
outstanding on such record date, plus the number of additional  Preferred Shares
or  Equivalent  Shares,  as the case may be, to be offered for  subscription  or
purchase (or into which


                                      -17-

<PAGE>



the  convertible  securities  so  to  be  offered  are  initially  convertible);
provided,  however, that in no event shall the consideration to be paid upon the
exercise  of one Right be less  than the  aggregate  par value of the  shares of
capital stock of the Company  issuable upon exercise of one Right.  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 a majority  of the  Company's  Board of  Directors,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent and shall be binding on the Rights  Agent and the  holders of the  Rights.
Preferred  Shares and Equivalent  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
Exercise Price shall be adjusted to be the Exercise Price which would then be in
effect if such record date had not been fixed.

                  (c) In case the Company  shall,  at any time after the date of
this  Agreement,  fix a record  date for the  making  of a  distribution  to all
holders of the Preferred  Shares or of any class or series of Equivalent  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,  if any, or a dividend  payable in Preferred  Shares) or  subscription
rights,  options or warrants  (excluding  those  referred to in Section  11(b)),
then,  in each such case,  the Exercise  Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such  record date by a fraction,  the  numerator  of which shall be the
Current Per Share Market Price of a Preferred  Share or an  Equivalent  Share on
such record date,  less the fair market value per Preferred  Share or Equivalent
Share (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 cash,  assets or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to a Preferred
Share or  Equivalent  Share,  as the case may be, and the  denominator  of which
shall be such Current Per Share Market Price of a Preferred  Share or Equivalent
Share  on such  record  date;  provided,  however,  that in no event  shall  the
consideration  to be paid  upon  the  exercise  of one  Right  be less  than the
aggregate par value of the shares of capital stock of the Company  issuable upon
exercise of one Right. 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 Exercise  Price shall be adjusted to be the Exercise  Price which would have
been in effect if such record date had not been fixed.

                  (d)  Anything  herein  to  the  contrary  notwithstanding,  no
adjustment in the Exercise Price shall be required unless such adjustment  would
require an increase or decrease of at least 1% in the Exercise Price;  provided,
however,  that any  adjustments  which by reason of this  Section  11(d) 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  ten-thousandth  of a Common  Share or other
share  or one  hundred-thousandth  of a  Preferred  Share,  as the  case may be.
Notwithstanding  the  first  sentence  of this  Section  11(d),  any  adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
(3) years from the date of the  transaction  which  requires such  adjustment or
(ii) the Expiration Date.

                  (e) If as a result of an  adjustment  made pursuant to Section
11(a) or 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital  stock  other than  Preferred  Shares,
thereafter  the number of such other shares so  receivable  upon exercise of any
Right  and,  if  required,  the  Exercise  Price  thereof,  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
Sections 11(a),  11(b),  11(c),  11(d),  11(g),  11(h),  11(i), 11(j), 11(k) and
11(l),  and the  provisions  of Sections 7, 9, 10, 13 and 14 with respect to the
Preferred Shares shall apply on like terms to any such other shares.

                  (f) All Rights originally issued by the Company  subsequent to
any adjustment  made to the Exercise Price hereunder shall evidence the right to
purchase,  at the adjusted  Exercise Price, the number of  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.

                  (g) Unless the Company  shall have  exercised  its election as
provided in Section  11(h),  upon each  adjustment  of the  Exercise  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  Exercise Price, that number of
Preferred Shares (calculated to the nearest one  hundred-thousandth  of a share)
obtained by (i)  multiplying  (x) the number of  Preferred  Shares  covered by a
Right immediately prior to this adjustment,  by (y) the Exercise Price in effect
immediately  prior to such adjustment of the Exercise  Price,  and (ii) dividing
the product so obtained by the Exercise Price in effect  immediately  after such
adjustment of the Exercise Price.

                  (h)  The  Company  may  elect  on or  after  the  date  of any
adjustment of the Exercise Price as a result of the calculations made in Section
11(b) or (c) to adjust the number of Rights, in substi tution for any adjustment
in the number of Preferred Shares 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-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  hundred-thousandth)  obtained  by
dividing the Exercise  Price in effect  immediately  prior to  adjustment of the
Exercise Price by the Exercise Price in effect  immediately  after adjustment of
the Exercise 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  Exercise  Price  is  adjusted  or any day
thereafter,  but, if the Rights Certificates have been issued, shall be at least
ten (10)  days  later  than  the  date of the  public  announcement.  If  Rights
Certificates  have been  issued,  upon each  adjustment  of the number of Rights
pursuant to this Section 11(h),  the Company shall,  as promptly as practicable,
cause to be  distributed  to  holders of record of Rights  Certificates  on such
record date Rights  Certificates  evidencing,  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  Rights
Certificates  held by such  holders  prior to the date of  adjustment,  and upon
surrender  thereof,  if  required  by  the  Company,   new  Rights  Certificates
evidencing all the Rights to


                                      -19-

<PAGE>



which such holders shall be entitled after such adjustment.  Rights Certificates
so to be distributed  shall be issued,  executed and countersigned in the manner
provided for herein (and may bear,  at the option of the  Company,  the adjusted
Exercise Price) and shall be registered in the names of the holders of record of
Rights Certificates on the record date specified in the public announcement.

                  (i)  Irrespective  of any adjustment or change in the Exercise
Price or the  number of  Preferred  Shares  issuable  upon the  exercise  of the
Rights, the Rights  Certificates  theretofore and thereafter issued may continue
to express the Exercise Price per one  one-thousandth  of a Preferred  Share and
the number of  one-thousandths  of a Preferred Share which were expressed in the
initial Rights Certificates issued hereunder.

                  (j) Before  taking any action that would  cause an  adjustment
reducing the Exercise Price below the par or stated value, if any, of the number
of  one-thousandths  of a Preferred  Share issuable upon exercise of the Rights,
the Company  shall take any  corporate  action  which may, in the opinion of its
counsel, be necessary in order that the Company may validly and legally issue as
fully  paid  and  nonassessable  shares  such  number  of  one-thousandths  of a
Preferred Share at such adjusted Exercise Price.

                  (k) In any case in which this Section 11 shall require that an
adjustment  in the  Exercise  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 number of  one-thousandths  of a Preferred  Share and other capital stock or
securities  of the Company,  if any,  issuable upon such exercise over and above
the number of  one-thousandths  of a Preferred  Share and other capital stock or
securities of the Company,  if any,  issuable upon such exercise on the basis of
the Exercise Price in effect prior to 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
(fractional  or  otherwise)  upon the  occurrence  of the event  requiring  such
adjustment.

                  (l)   Anything   in   this   Section   11  to   the   contrary
notwithstanding,  prior to the Distribution  Date, the Company shall be entitled
to make such reductions in the Exercise 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 (i)  consolidation
or subdivision of the Preferred or Common Shares,  (ii) issuance wholly for cash
of any Preferred or Common Shares at less than the current  market price,  (iii)
issuance  wholly for cash of Preferred or Common Shares or  securities  which by
their terms are convertible into or exchangeable for Preferred or Common Shares,
(iv) stock dividends or (v) issuance of rights,  options or warrants referred to
in this Section 11, hereafter made by the Company to holders of its Preferred or
Common Shares shall not be taxable to such stockholders.

                  (m)  The  Company   covenants  and  agrees  that,   after  the
Distribution  Date,  it will not,  except as  permitted by Sections 23, 24 or 27
hereof,  take (or permit to be taken)  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.

                  (n) In the event the Company  shall at any time after the date
of this  Agreement (A) declare a dividend on the Common Shares payable in Common
Shares, (B) subdivide the outstanding Common Shares, (C) combine the outstanding
Common  Shares (by reverse stock split or  otherwise)  into a smaller  number of
Common   Shares,   or  (D)  issue  any  shares  of  its   capital   stock  in  a
reclassification  of the Common Shares (including any such  reclassification  in
connection with a consolidation or merger in which the Company is the continuing
or  surviving  corporation),  then,  in each such  event,  except  as  otherwise
provided in this Section  11(a) and Section  7(e) hereof:  (1) each Common Share
(or  shares of  capital  stock  issued in such  reclassification  of the  Common
Shares) outstanding  immediately  following such time shall have associated with
it the number of Rights as were  associated  with one Common  Share  immediately
prior to the occurrence of the event described in clauses (A)-(D) above; (2) the
Exercise  Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price  thereafter  shall equal the result obtained
by multiplying the Exercise Price in effect  immediately prior to such time by a
fraction,  the  numerator  of which shall be the total  number of Common  Shares
outstanding  immediately  prior to the event described in clauses (A)-(D) above,
and the  denominator  of which  shall  be the  total  number  of  Common  Shares
outstanding  immediately after such event;  provided,  however, that in no event
shall the  consideration  to be paid upon the exercise of one Right be less than
the aggregate  par value of the shares of capital stock of the Company  issuable
upon  exercise  of such  Right;  and  (3) the  number  of  one-thousandths  of a
Preferred  Share (or  shares of such  other  capital  stock)  issuable  upon the
exercise  of each Right  outstanding  after such event shall equal the number of
one-thousandths  of a Preferred Share (or shares of such other capital stock) as
were issuable with respect to one Right  immediately  prior to such event.  Each
Common Share that shall become  outstanding  after an  adjustment  has been made
pursuant  to this  Section  11(n)  shall have  associated  with it the number of
Rights,  exercisable at the Exercise Price and for the number of one-thousandths
of a Preferred Share (or shares of such other capital stock) as one Common Share
has  associated  with it immediately  following the adjustment  made pursuant to
this Section 11(n).  If an event occurs which would require an adjustment  under
both this Section 11(n) and Section  11(a)(ii) hereof,  the adjustment  provided
for in this  Section  11(n) shall be in addition to, and shall be made prior to,
any adjustment required pursuant to Section 11(a)(ii) hereof.

         Section 12. Certificate of Adjusted Exercise Price or Number of Shares.
Whenever an  adjustment  is made as  provided in Sections 11 and 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 Preferred Shares a copy of
such certificate and (c) mail a brief summary thereof to each holder of a Rights
Certificate in accordance with Section 26 hereof.  Notwithstanding the foregoing
sentence,  the  failure of the Company to make such  certification  or give such
notice shall not affect the validity of such  adjustment  or the force or effect
of the  requirement  for  such  adjustment.  The  Rights  Agent  shall  be fully
protected in relying on any such  certificate  and on any  adjustment  contained
therein,  and  shall  not  be  obligated  or  responsible  for  calculating  any
adjustment, nor shall it be deemed to have knowledge of such adjustment,  unless
and until it shall have received such certificate.

Earning Power.

                  (a) In the event that, following a Triggering Event,  directly
or indirectly:

                             (i) the Company  shall  consolidate  with, or merge
         with and into, any other Person (other than a  wholly-owned  Subsidiary
         of the Company in a transaction  the  principal  purpose of which is to
         change the state of  incorporation  of the Company  and which  complies
         with Section 11(m), 11(n) hereof);

                            (ii) any Person 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 of the Company); or

                           (iii) 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 wholly-owned  Subsidiaries in one or more
         transactions,  each of which  individually (and together) complies with
         Section 11(m) hereof),

                                    then, concurrent with and in each such case,

                                    (A)  each  holder  of  a  Right  (except  as
                  provided in Section 7(e)  hereof)  shall  thereafter  have the
                  right to receive,  upon the exercise  thereof at a price equal
                  to the Total Exercise Price  applicable  immediately  prior to
                  the occurrence of the Section 13 Event in accordance  with the
                  terms of this Agreement, such number of validly authorized and
                  issued, fully paid,  nonassessable and freely tradeable Common
                  Shares of the Principal Party (as hereinafter  defined),  free
                  of any liens,  encumbrances,  rights of first refusal or other
                  adverse  claims,  as shall be equal to the result  obtained by
                  dividing such Total  Exercise  Price by 50% of the Current Per
                  Share  Market  Price of the  Common  Shares of such  Principal
                  Party on the date of  consummation  of such  Section 13 Event,
                  provided,  however,  that the Exercise Price and the number of
                  Common  Shares  of such  Principal  Party so  receivable  upon
                  exercise of a Right shall be subject to further  adjustment as
                  appropriate in accordance with Section 11(e) hereof;

                                    (B) such Principal Party shall thereafter be
                  liable for,  and shall  assume,  by virtue of such  Section 13
                  Event,  all the obligations and duties of the Company pursuant
                  to this Agreement;

                                    (C) 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 Event;

                                    (D) such  Principal  Party  shall  take such
                  steps  (including,  but not limited to, the  reservation  of a
                  sufficient number of its Common Shares) in connection with the
                  consummation  of any such  transaction  as may be necessary to
                  ensure  that  the  provisions   hereof  shall   thereafter  be
                  applicable, as nearly as reasonably may be, in relation to its
                  Common Shares thereafter  deliverable upon the exercise of the
                  Rights; and

                                    (E) upon the  subsequent  occurrence  of any
                  consolidation,  merger,  sale or  transfer  of assets or other
                  extraordinary  transaction in respect of such Principal Party,
                  each holder of a Right shall thereupon be entitled to receive,
                  upon  exercise  of a Right and  payment of the Total  Exercise
                  Price as provided in this Section  13(a),  such cash,  shares,
                  rights,  warrants and other  property  which such holder would
                  have been entitled to receive had such holder,  at the time of
                  such  transaction,  owned the Common  Shares of the  Principal
                  Party  receivable  upon the exercise of such Right pursuant to
                  this Section 13(a),  and such Principal  Party shall take such
                  steps (including, but not limited to, reservation of shares of
                  stock) as may be necessary to permit the  subsequent  exercise
                  of the  Rights in  accordance  with the terms  hereof for such
                  cash, shares, rights, warrants and other property.

                                    (F) For purposes hereof, the "earning power"
                  of the Company and its  Subsidiaries  shall be  determined  in
                  good faith by the Company's Board of Directors on the basis of
                  the  operating  earnings  of  each  business  operated  by the
                  Company and its  Subsidiaries  during the three  fiscal  years
                  preceding the date of such  determination  (or, in the case of
                  any  business  not  operated by the Company or any  Subsidiary
                  during three full fiscal years preceding such date, during the
                  period  such  business  was  operated  by the  Company  or any
                  Subsidiary).

                  (b) For purposes of this Agreement, the term "Principal Party"
shall mean:

                           (i)  in the  case  of any  transaction  described  in
         clause (i) or (ii) of Section 13(a) hereof:  (A) the Person that is the
         issuer of the securities  into which the Common Shares are converted in
         such  merger  or  consolidation,  or,  if there  is more  than one such
         issuer,  the  issuer  the  Common  Shares  of which  have the  greatest
         aggregate market value of shares  outstanding,  or (B) if no securities
         are so issued, (x) the Person that is the other party to the merger, if
         such Person  survives  said merger,  or, if there is more than one such
         Person,  the  Person  the  Common  Shares  of which  have the  greatest
         aggregate market value of shares  outstanding or (y) if the Person that
         is the other  party to the merger  does not  survive  the  merger,  the
         Person  that does  survive  the  merger  (including  the  Company if it
         survives) or (z) the Person resulting from the consolidation; and

                           (ii) in the  case  of any  transaction  described  in
         clause  (iii) of Section  13(a)  hereof,  the Person  that is the party
         receiving  the  greatest   portion  of  the  assets  or  earning  power
         transferred  pursuant to such transaction or transactions,  or, if more
         than one Person  that is a party to such  transaction  or  transactions
         receives the same portion of the assets or earning power so


                                      -23-

<PAGE>



         transferred  and each  such  portion  would,  were it not for the other
         equal  portions,  constitute  the  greatest  portion  of the  assets or
         earning power so transferred,  or if the Person  receiving the greatest
         portion of the assets or earning power cannot be determined,  whichever
         of such  Persons is the  issuer of Common  Shares  having the  greatest
         aggregate market value of shares outstanding;

provided,  however,  that in any such case  described  in the  foregoing  clause
(b)(i) or (b)(ii),  if the Common  Shares of such Person are not at such time or
have not been continuously  over the preceding  12-month period registered under
Section 12 of the Exchange  Act, then (1) if such Person is a direct or indirect
Subsidiary  of another  Person  the Common  Shares of which are and have been so
registered,  the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of which are and have been so registered,  the term "Principal
Party" shall refer to  whichever of such Persons is the issuer of Common  Shares
having the greatest aggregate market value of shares outstanding, or (3) if such
Person is owned,  directly or  indirectly,  by a joint venture  formed by two or
more Persons that are not owned,  directly or indirectly by the same Person, the
rules set forth in clauses  (1) and (2) above  shall apply to each of the owners
having an interest in the  venture as if the Person  owned by the joint  venture
was a Subsidiary of both or all of such joint venturers, and the Principal Party
in each such case shall bear the obligations set forth in this Section 13 in the
same ratio as its interest in such Person bears to the total of such interests.

                  (c) The  Company  shall not  consummate  any  Section 13 Event
unless the Principal Party shall have a sufficient  number of authorized  Common
Shares that have not been issued or reserved for issuance to permit the exercise
in full of the  Rights in  accordance  with this  Section  13 and  unless  prior
thereto the Company and such issuer  shall have  executed  and  delivered to the
Rights Agent a  supplemental  agreement  confirming  that such  Principal  Party
shall,  upon  consummation  of such Section 13 Event,  assume this  Agreement in
accordance  with  Sections  13(a) and  13(b)  hereof,  that all  rights of first
refusal or preemptive rights in respect of the issuance of Common Shares of such
Principal Party upon exercise of outstanding Rights have been waived, that there
are no rights, warrants, instruments or securities outstanding or any agreements
or  arrangements  which, as a result of the  consummation  of such  transaction,
would eliminate or substantially  diminish the benefits  intended to be afforded
by the  Rights and that such  transaction  shall not result in a default by such
Principal  Party under this  Agreement,  and further  providing that, as soon as
practicable after the date of such Section 13 Event, such Principal Party will:

                             (i) prepare and file a registration statement under
         the  Securities  Act with  respect  to the  Rights  and the  securities
         purchasable upon exercise of the Rights on an appropriate form, use its
         best efforts to cause such  registration  statement to become effective
         as soon as  practicable  after such filing and use its best  efforts to
         cause  such   registration   statement  to  remain  effective  (with  a
         prospectus at all times meeting the requirements of the Securities Act)
         until the Expiration  Date, and similarly  comply with applicable state
         securities laws;

                            (ii) use its best  efforts to list (or  continue the
         listing of) the Rights and the securities  purchasable upon exercise of
         the Rights on a national securities exchange or to meet


                                      -24-

<PAGE>



         the  eligibility  requirements  for  quotation  on Nasdaq  and list (or
         continue the listing of) the Rights and the securities purchasable upon
         exercise of the Rights on Nasdaq; and

                           (iii)  deliver to  holders  of the Rights  historical
         financial  statements  for such  Principal  Party  which  comply in all
         respects  with the  requirements  for  registration  on Form 10 (or any
         successor form) under the Exchange Act.

         In the event  that at any time  after the  occurrence  of a  Triggering
Event some or all of the Rights  shall not have been  exercised at the time of a
transaction  described in this Section 13, the Rights which have not theretofore
been  exercised  shall  thereafter  be  exercisable  in the manner  described in
Section  13(a)  (without  taking into account any prior  adjustment  required by
Section 11(a)(ii)).

                  (d) In case the  "Principal  Party"  for  purposes  of Section
13(b)  hereof  has  provision  in  any of its  authorized  securities  or in its
certificate  of  incorporation  or by-laws  or other  instrument  governing  its
corporate  affairs,  which  provision  would have the effect of (i) causing such
Principal Party to issue (other than to holders of Rights pursuant to Section 13
hereof),  in  connection  with, or as a consequence  of, the  consummation  of a
Section 13 Event,  Common Shares or Equivalent Shares of such Principal Party at
less  than the then  Current  Per  Share  Market  Price  thereof  or  securities
exercisable for, or convertible into, Common Shares or Equivalent Shares of such
Principal  Party at less than such then Current Per Share Market Price,  or (ii)
providing for any special payment,  tax or similar  provision in connection with
the  issuance  of the Common  Shares of such  Principal  Party  pursuant  to the
provisions of Section 13 hereof,  then, in such event, the Company hereby agrees
with each holder of Rights  that it shall not  consummate  any such  transaction
unless prior  thereto the Company and such  Principal  Party shall have executed
and delivered to the Rights Agent a  supplemental  agreement  providing that the
provision in question of such Principal  Party shall have been canceled,  waived
or amended,  or that the authorized  securities  shall be redeemed,  so that the
applicable  provision will have no effect in connection with or as a consequence
of, the consummation of the proposed transaction.

                  (e) The Company covenants and agrees that it shall not, at any
time  after the  Distribution  Date,  effect or permit to occur any  Section  13
Event,  if (i) at the time or immediately  after such Section 13 Event there are
any  rights,   warrants  or  other  instruments  or  securities  outstanding  or
agreements in effect which would  substantially  diminish or otherwise eliminate
the   benefits   intended  to  be  afforded  by  the  Rights,   (ii)  prior  to,
simultaneously with or immediately after such Section 13 Event, the stockholders
of the Person who constitutes,  or would  constitute,  the "Principal Party" for
purposes of Section  13(b) hereof shall have received a  distribution  of Rights
previously  owned by such Person or any of its Affiliates or Associates or (iii)
the form or nature of  organization  of the  Principal  Party would  preclude or
limit the exercisability of the Rights.

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

         Section 14.  Fractional Rights and Fractional Shares.


                                      -25-

<PAGE>



                  (a) The Company  shall not be required to issue  fractions  of
Rights or to distribute Rights Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Rights  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,  as determined pursuant to
the second sentence of Section 1(j) hereof.

                  (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 which evidence fractional  Preferred Shares (other than
fractions  that are  integral  multiples  of one  one-thousandth  of a Preferred
Share).  Interests in 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, 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 Rights  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 a Preferred  Share.  For  purposes of this Section  14(b),  the current
market value of a Preferred  Share shall be one thousand times the closing price
of a Common Share (as determined pursuant to the second sentence of Section 1(j)
hereof) for the Trading Day immediately prior to the date of such exercise.

                  (c) The Company  shall not be required to issue  fractions  of
Common Shares or to distribute  certificates  which evidence  fractional  Common
Shares  upon the  exercise or  exchange  of Rights.  In lieu of such  fractional
Common  Shares,  the  Company  shall  pay to the  registered  holders  of Rights
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 a Common
Share.  For purposes of this Section 14(c), the current market value of a Common
Share shall be the closing  price of a Common Share (as  determined  pursuant to
the second  sentence of Section  1(j)  hereof)  for the Trading Day  immediately
prior to the date of such exercise.

                  (d) The  holder  of a Right  by the  acceptance  of the  Right
expressly  waives  his or her  right to  receive  any  fractional  Rights or any
fractional  shares  (other than  fractions  that are  integral  multiples of one
one-thousandth of a Preferred Share) upon exercise of a Right.

         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 Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares);  and any registered holder of any Rights  Certificate (or, prior
to the  Distribution  Date,  of the Common  Shares),  without the consent of the
Rights Agent or of the holder of any other Rights


                                      -26-

<PAGE>



Certificate (or, prior to the Distribution Date, of the Common Shares),  may, in
his or her own behalf and for his or her 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 or her right to exercise the Rights  evidenced
by such Rights Certificate in the manner provided in such Rights 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 Rights  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 Rights  Certificates are
transferable  only on the registry  books of the Rights Agent if  surrendered at
the  principal  office  or  offices  of the  Rights  Agent  designated  for such
purposes,  duly endorsed or accompanied  by a proper  instrument of transfer and
with the appropriate forms and certificates fully executed; and

                  (c) subject to Sections 6(a) and 7(f) hereof,  the Company and
the  Rights  Agent  may deem and  treat  the  person  in whose  name the  Rights
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
Rights  Certificates or the associated Common Shares  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.

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

         Section 18. Concerning the Rights Agent.

                  (a) 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 gross 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 indemnity  provided for herein shall survive the
expiration of the Rights, the termination of this Agreement, and the resignation
or removal of the Rights Agent.  The costs and expenses of enforcing  this right
of indemnification shall also be paid by the Company.

                  (b) The Rights Agent may  conclusively  rely upon and 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  Rights  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 reasonably 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.

                  (c)   Notwithstanding   anything  in  this  Agreement  to  the
contrary, in no event shall the Rights Agent be liable for special,  indirect or
consequential  loss or damage of any kind whatsoever  (including but not limited
to lost profits), even if the Rights Agent has been advised of the likelihood of
such loss or damage and regardless of the form of the action.

         Section 19.  Merger or Consolidation or Change of Name of Rights Agent.

                  (a)  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  corpora  tion
succeeding to the corporate  trust business of the Rights Agent or any successor
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,  however,  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 Rights  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
Rights Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been  countersigned,  any successor Rights Agent may
countersign such Rights Certificates either in the name


                                      -28-

<PAGE>



of the  predecessor  Rights Agent or in the name of the successor  Rights Agent;
and in all such  cases  such  Rights  Certificates  shall  have  the full  force
provided in the Rights Certificates and in this Agreement.

                  (b) In case at any time the name of the Rights  Agent shall be
changed  and at  such  time  any of the  Rights  Certificates  shall  have  been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Rights  Certificates so  countersigned;  and in
case  at  that  time  any  of  the  Rights  Certificates  shall  not  have  been
countersigned,  the Rights Agent may countersign such Rights Certificates either
in its prior name or in its  changed  name;  and in all such  cases such  Rights
Certificates  shall have the full force provided in the Rights  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,  and no  implied  duties  or  obligations  shall be read  into  this
Agreement  against the Rights Agent, by all of which the Company and the holders
of Rights Certificates, by their acceptance thereof, shall be bound:

                  (a) Before the Rights Agent acts or refrains from acting,  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 (including,  without limitation, the identity of any Acquiring Person and
the determination of Current Per Share Market Price) 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 Chief Financial Officer,  the
Secretary or any Assistant  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 gross  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
Rights  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  hereof by the  Rights  Agent) or in  respect of the
validity or execution of any Rights Certificate (except its countersignature


                                      -29-

thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any change in the  exercisability  of the Rights
or any adjustment in the terms of the Rights  (including  the manner,  method or
amount  thereof)  provided  for  in  Sections  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 Rights
Certificates  after  receipt  by the  Rights  Agent of a  certificate  furnished
pursuant to Section 12 describing  such change or  adjustment);  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 Rights  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 Chief Financial Officer, the Secretary or any
Assistant Secretary 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.  Any application by the Rights Agent for written instructions from
the  Company  may, at the option of the Rights  Agent,  set forth in writing any
action  proposed  to be taken or omitted by the Rights  Agent  under this Rights
Agreement  and the date on and/or after which such action shall be taken or such
omission shall be effective. The Rights Agent shall not be liable for any action
taken by, or  omission  of,  the  Rights  Agent in  accordance  with a  proposal
included  in any  such  application  on or  after  the  date  specified  in such
application  (which date shall not be less than five (5) Business Days after the
date any officer of the Company actually receives such  application,  unless any
such officer shall have  consented in writing to an earlier date) unless,  prior
to taking any such action (or the  effective  date in the case of an  omission),
the Rights Agent shall have received  written  instructions  in response to such
application specifying the action to be taken or omitted.

                  (h) The Rights Agent and any stockholder, 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 the 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


                                      -30-

<PAGE>



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.

                  (j) No provision of this  Agreement  shall  require the Rights
Agent to expend or risk its own funds or otherwise incur any financial liability
in the  performance  of any of its duties  hereunder  or in the  exercise of its
rights if there shall be reasonable grounds for believing that repayment of such
funds  or  adequate  indemnification  against  such  risk  or  liability  is not
reasonably assured to it.

                  (k) If, with respect to any Rights Certificate  surrendered to
the Rights Agent for exercise or transfer,  the certificate attached to the form
of  assignment  or form of election to purchase,  as the case may be, has either
not been  completed or indicates  an  affirmative  response to clause 1 and/or 2
thereof, the Rights Agent shall not take any further action with respect to such
requested exercise or transfer without first consulting with the Company.

                  (l) The Rights  Agent  shall not be required to take notice or
be deemed to have notice of any fact, event or determination (including, without
limitation,  any dates or events defined in this Agreement or the designation of
any Person as an Acquiring Person,  Affiliate or Associate) under this Agreement
unless and until the Rights Agent shall be  specifically  notified in writing by
the Company of such fact, event of determination.

         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  thirty  (30) days'  notice in writing  mailed to the  Company  and to each
transfer  agent of the  Preferred  Shares and the Common Shares by registered or
certified mail, and, at the expense of the Company, to the holders of the Rights
Certificates by first-class mail. The Company may remove the Rights Agent or any
successor  Rights Agent upon thirty (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  Preferred  Shares and the Common Shares by registered or certified
mail, and to the holders of the Rights  Certificates by first-class mail. 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 of thirty (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 Rights  Certificate (who shall, with such notice,  submit his
or her Rights  Certificate  for inspection by the Company),  then the registered
holder  of  any  Rights   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 any state of the United States,  in good standing,  which is authorized under
such laws to exercise  corporate  trust or  stockholder  services  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 $50 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


                                      -31-

<PAGE>



further assurance,  conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such  appointment,  the Company shall file notice
thereof in writing with the predecessor  Rights Agent and each transfer agent of
the Preferred Shares and the Common Shares, and mail a notice thereof in writing
to the registered holders of the Rights 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.

         Section 22. Issuance of New Rights Certificates. Notwithstanding any of
the provisions of this  Agreement or of the Rights to the contrary,  the Company
may, at its option, issue new Rights Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the  Exercise  Price  and the  number  or kind or  class of  shares  or other
securities  or  property  purchasable  under  the  Rights  Certificates  made in
accordance  with the provisions of this  Agreement.  In addition,  in connection
with the issuance or sale of Common Shares following the  Distribution  Date and
prior to the redemption or expiration of the Rights, the Company (a) shall, with
respect to Common  Shares so issued or sold  pursuant  to the  exercise of stock
options  or  under  any  employee  plan or  arrangement  or upon  the  exercise,
conversion  or exchange of other  securities of the Company  outstanding  at the
date  hereof  or  upon  the  exercise,  conversion  or  exchange  of  securities
hereinafter  issued by the Company  and (b) may,  in any other  case,  if deemed
necessary or appropriate by the Board of Directors of the Company,  issue Rights
Certificates  representing  the appropriate  number of Rights in connection with
such issuance or sale;  provided,  however,  that (i) no such Rights Certificate
shall be issued  and this  sentence  shall be null and void ab initio if, and to
the extent that, such issuance or this sentence would create a significant  risk
of or result in material  adverse tax  consequences to the Company or the Person
to whom such Rights  Certificate  would be issued or would create a  significant
risk of or result in such options' or employee plans' or  arrangements'  failing
to qualify for otherwise available special tax treatment and (ii) no such Rights
Certificate shall be issued if, and to the extent that,  appropriate  adjustment
shall otherwise have been made in lieu of the issuance thereof.

         Section 23. Redemption.

                  (a) The Company  may,  at its option and with the  approval of
the  Board of  Directors,  at any time  prior to the  Close of  Business  on the
earlier  of (i) the tenth day  following  the Shares  Acquisition  Date (or such
later date as may be determined  by action of a majority of the Company's  Board
of  Directors  and  publicly  announced  by the  Company)  and  (ii)  the  Final
Expiration Date, redeem all but not less than all the then outstanding Rights at
a  redemption  price of $0.01 per Right,  appropriately  adjusted to reflect any
stock split,  stock  dividend or similar  transaction  occurring  after the date
hereof  (such  redemption  price being  herein  referred  to as the  "Redemption
Price") and the Company may, at its option,  pay the Redemption  Price either in
Common  Shares  (based on the Current Per Share Market Price thereof at the time
of redemption) or cash. Such redemption of the Rights by the Company 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.  The date on which the Board of
Directors  elects to make the redemption  effective  shall be referred to as the
"Redemption Date."


                                      -32-

<PAGE>



                  (b)  Notwithstanding  the provision of Section  23(a),  in the
event that a majority  of the Board of  Directors  of the  Company is elected by
stockholder action by written consent or at a special meeting of stockholders (a
meeting other than a regularly scheduled annual meeting), then until the earlier
to occur of (i) the 180th day  following the  effectiveness  of such election or
(ii) the next regular annual meeting of  shareholders  of the Company  following
the  effectiveness  of such election  (including any postponement or adjournment
thereof),  the Rights  shall not be redeemed if such  redemption  is  reasonably
likely to have the  purpose  or effect of  facilitating  a  Transaction  with an
Interested Person.

                  (c)  Immediately  upon the action of the Board of Directors of
the Company ordering the redemption of the Rights,  evidence of which shall have
been filed with the Rights Agent, 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 ten (10) days after the action of
the Board of Directors  ordering the redemption of the Rights, the Company shall
give notice of such  redemption  to the Rights Agent and the holders of the then
outstanding  Rights by  mailing  such  notice to all such  holders 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 which is mailed in the manner herein provided shall be
deemed given, whether or not the holder receives the notice. Each such 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) Subject to applicable  laws,  rules and  regulations,  and
subject to subsection 24(c) below, the Company may, at its option,  by action of
the Board of Directors,  at any time after the occurrence of a Triggering Event,
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 the Company,  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
ordering the exchange of any Rights pursuant to subsection 24(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


                                      -33-

<PAGE>



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 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  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  which 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  which will be  exchanged.  Any partial
exchange  shall be effected  pro rata based on the number of Rights  (other than
Rights which 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 Section 24(a), the Company
shall either take such action as may be necessary to authorize additional Common
Shares for issuance upon exchange of the Rights or alternatively,  at the option
of a majority of the Board of Directors, with respect to each Right (i) pay cash
in an amount equal to the Current  Value (as  hereinafter  defined),  in lieu of
issuing  Common  Shares  in  exchange  therefor,  or (ii)  issue  debt or equity
securities or a combination thereof,  having a value equal to the Current Value,
in lieu of issuing  Common  Shares in exchange  for each such  Right,  where the
value  of  such  securities  shall  be  determined  by a  nationally  recognized
investment banking firm selected by majority vote of the Board of Directors,  or
(iii)  deliver any  combination  of cash,  property,  Common Shares and/or other
securities having a value equal to the Current Value in exchange for each Right.
For  purposes  of this  Section  24(c) only,  the  Current  Value shall mean the
product of the Current Per Share  Market  Price of Common  Shares on the date of
the occurrence of the event described above in subparagraph  (a),  multiplied by
the number of Common Shares for which the Right  otherwise would be exchangeable
if there  were  sufficient  shares  available.  To the extent  that the  Company
determines that some action need be taken pursuant to clauses (i), (ii) or (iii)
of this  Section  24(c),  the Board of  Directors  may  temporarily  suspend the
exercisability of the Rights for a period of up to sixty (60) days following the
date on which the event described in Section 24(a) shall have occurred, in order
to seek any  authorization  of  additional  Common  Shares  and/or to decide the
appropriate  form of distribution to be made pursuant to the above provision and
to determine the value thereof. In the event of any such suspension, the Company
shall issue a public announcement  stating that the exercisability of the Rights
has been temporarily suspended.

                   (d) The Company  shall not be required to issue  fractions of
Common Shares or to distribute  certificates  which evidence  fractional  Common
Shares.  In lieu of such  fractional  Common Shares,  there shall be paid to the
registered  holders  of the  Rights  Certificates  with  regard  to  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 (as
determined pursuant to the second sentence of Section 1(j) hereof).

                  (e) The Company  may, at its option,  by majority  vote of the
Board of  Directors,  at any time  before any  Person  has  become an  Acquiring
Person, exchange all or part of the then


                                      -34-

<PAGE>



outstanding  Rights for rights of substantially  equivalent value, as determined
reasonably and with good faith by the Board of Directors,  based upon the advice
of one or more nationally recognized investment banking firms.

                  (f)  Immediately  upon the  action of the  Board of  Directors
ordering the exchange of any Rights pursuant to subsection 24(e) 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 rights in  exchange  therefor as has
been determined by the Board of Directors in accordance  with  subsection  24(e)
above.  The Company  shall 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  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 transfer agent for the Common Shares
of the Company.  Any notice which 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 Rights will be
effected.

         Section 25.  Notice of Certain Events.

                  (a) In case the Company  shall  propose to effect or permit to
occur any  Triggering  Event or Section 13 Event,  the Company shall give notice
thereof to each holder of Rights in  accordance  with Section 26 hereof at least
twenty (20) days prior to occurrence of such Triggering Event or such Section 13
Event.

                  (b) In case any  Triggering  Event or Section  13 Event  shall
occur,  then,  in any  such  case,  the  Company  shall  as soon as  practicable
thereafter  give to each  holder of a Rights  Certificate,  in  accordance  with
Section 26 hereof, a notice of the occurrence of such event, which shall specify
the event and the  consequences of the event to holders of Rights under Sections
11(a)(ii) and 13 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 Rights  Certificate
to or on the Company shall be sent by registered or certified  mail and shall be
deemed given upon receipt,  addressed (until another address is filed in writing

         Section 27.  Supplements and Amendments.

                  (a)  Prior  to the  occurrence  of a  Distribution  Date,  the
Company  may  supplement  or amend this  Agreement  in any  respect  without the
approval of any holders of Rights and the Rights Agent shall,  if the Company so
directs, execute such supplement or amendment.  From and after the occurrence of
a  Distribution  Date,  the Company  and the Rights  Agent may from time to time
supplement or amend this Agreement without the approval of any holders of Rights
in order to (i) cure any  ambiguity,  (ii) correct or  supplement  any provision
contained  herein  which  may  be  defective  or  inconsistent  with  any  other
provisions herein, (iii) shorten or lengthen any time period hereunder,  or (iv)
to change or supplement the provisions  hereunder in any manner that the Company
may deem  necessary  or  desirable  and that  shall  not  adversely  affect  the
interests  of the  holders  of  Rights  (other  than an  Acquiring  Person or an
Affiliate or Associate of an Acquiring Person); provided, this Agreement may not
be  supplemented  or  amended  to  lengthen,  pursuant  to clause  (iii) of this
sentence,  (A) a time period relating to when the Rights may be redeemed at such
time as the Rights are not then  redeemable  or (B) any other time period unless
such  lengthening is for the purpose of protecting,  enhancing or clarifying the
rights  of,  and/or  the  benefits  to, the  holders  of Rights  (other  than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person).  Upon the
delivery of a certificate from an appropriate officer of the Company that states
that the proposed  supplement  or amendment is in  compliance  with the terms of
this Section 27, the Rights Agent shall  execute such  supplement  or amendment.
Prior to the Distribution  Date, the interests of the holders of Rights shall be
deemed coincident with the interests of the holders of Common Shares.

                  (b)  Notwithstanding  the provisions of Section 27(a),  in the
event that a majority  of the Board of  Directors  of the  Company is elected by
stockholder action by written consent or at a special meeting of stockholders (a
meeting other than a regularly scheduled annual meeting), then until the


                                      -36-

earlier  to occur of (i) the  180th  day  following  the  effectiveness  of such
election or (ii) the next regular annual meeting of  stockholders of the Company
following the  effectiveness  of such election  (including any  postponement  or
adjournment thereof), this Rights Agreement shall not be supplemented or amended
in any manner  reasonably likely to have the purpose or effect of facilitating a
Transaction with an Interested Person.

                  (c)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  no supplement or amendment  that changes the rights and duties of the
Rights Agent under this  Agreement  will be  effective  against the Rights Agent
without the execution of such supplement or amendment by the Rights Agent.

         Section  28.  Successors.  All the  covenants  and  provisions  of this
Agreement  by or for the benefit of the  Company or the Rights  Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

         Section 29. Determinations and Actions by the Board of Directors,  etc.
For all  purposes of this  Agreement,  any  calculation  of the number of Common
Shares outstanding at any particular time, including for purposes of determining
the particular  percentage of such outstanding Common Shares of which any Person
is the Beneficial  Owner,  shall be made in accordance with the last sentence of
Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act.
The  Board of  Directors  of the  Company  shall  have the  exclusive  power and
authority to  administer  this  Agreement  and to exercise all rights and powers
specifically  granted to the Board,  or the  Company,  or as may be necessary or
advisable  in  the   administration  of  this  Agreement,   including,   without
limitation,  the  right  and  power  to (i)  interpret  the  provisions  of this
Agreement and (ii) make all determinations deemed necessary or advisable for the
administration  of this Agreement  (including a  determination  to redeem or not

                CERTIFICATE OF DESIGNATION OF RIGHTS, PREFERENCES

Delaware

         Quantum  Corporation,,  a  Delaware  corporation  (the  "Corporation"),
organized  and  existing  under the laws of the State of  Delaware,  does by its
[President] and under its corporate seal hereby certifies as follows:

         1. That pursuant to the authority conferred upon the Board of Directors
by the Restated  Certificate of Incorporation of the said Corporation,  the said
Board of Directors on July 21, 1988  designated a series of 1,000,000  shares of
Preferred Stock designated as Series A Junior Participating  Preferred Stock and
filed a Revised Form of Certificate of  Designations,  Preferences and Rights of
Series A Junior  Participating  Preferred  Stock on  December  9,  1988 with the
Secretary of State of the State of Delaware.

         2. That no shares of Series A Junior Participating Preferred Stock have
been issued to date.

         3. That pursuant to the authority conferred upon the Board of Directors
by the Restated  Certificate of Incorporation of the said Corporation,  the said
Board of Directors on May 15, 1998 adopted the following resolution changing the
designation of the Series A Junior Participating Preferred Stock:

         "RESOLVED:  That pursuant to the authority granted to and vested in the
         Board of Directors of the Corporation in accordance with the provisions
         of its  Certificate  of  Incorporation,  the Board of Directors  hereby
         amends and restates the  designation  of the Company's  Series A Junior
         Participating  Preferred  Stock,  effective as of the record date,  and
         fixes the relative  rights,  preferences  and  limitations  thereof (in
         addition  to  the   provisions   set  forth  in  the   Certificate   of
         Incorporation of the Corporation, which are applicable to the Preferred
         Stock of all classes and series), 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
Junior Participating  Preferred Stock shall have a par value of $0.01 per share,
and the number of shares constituting such series shall be 1,000,000.

         Section 2. Proportional Adjustment.  In the event the Corporation shall
at any time  after  the  issuance  of any  share or  shares  of  Series A Junior
Participating Preferred Stock (i) declare any dividend


<PAGE>



on Common Stock of the Corporation  ("Common Stock") payable in shares of Common
Stock,  (ii)  subdivide  the  outstanding  Common  Stock  or (iii)  combine  the
outstanding Common Stock into a smaller number of shares, then in each such case
the Corporation  shall  simultaneously  effect a proportional  adjustment to the
number of outstanding shares of Series A Junior  Participating  Preferred Stock,
if any.

         Section  3. Dividends and Distributions.

                  (a) Subject to the prior and superior  right of the holders of
any shares of any series of Preferred  Stock  ranking  prior and superior to the
shares  of  Series  A Junior  Participating  Preferred  Stock  with  respect  to
dividends,  the  holders  of shares of Series A Junior  Participating  Preferred
Stock  shall be  entitled  to receive  when,  as and if declared by the Board of
Directors out of funds legally available for that purpose,  quarterly  dividends
payable in cash on the last day of January, April, July and October 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 Junior  Participating
Preferred  Stock,  in an amount per share (rounded to the nearest cent) equal to
1,000 times the  aggregate  per share  amount of all cash  dividends,  and 1,000
times the aggregate per share amount (payable in kind) of all non-cash dividends
or other  distributions  other  (except as provided in Section 2 hereof)  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 Participating Preferred
Stock.

                  (b) The  Corporation  shall declare a dividend or distribution
on the Series A Participating Preferred Stock as provided in paragraph (a) above
immediately  after it declares a dividend or  distribution  on the Common  Stock
(other than a dividend payable in shares of Common Stock).

                  (c) Dividends  shall begin to accrue on outstanding  shares of
Series A Participating  Preferred Stock from the Quarterly Dividend Payment Date
next  preceding  the date of  issue of such  shares  of  Series A  Participating
Preferred Stock,  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
Participating  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 from such  Quarterly  Dividend  Payment  Date.
Accrued but unpaid  dividends  shall not bear  interest.  Dividends  paid on the
shares  of Series A  Participating  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  Participating  Preferred  Stock
entitled to receive  payment of a dividend  or  distribution  declared  thereon,
which  record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

                  (b) Except as otherwise provided herein or by law, the holders
of shares of Series A Participating Preferred Stock and the holders of shares of
Common Stock shall vote together as one class on all matters submitted to a vote
of stockholders of the Corporation.

                  (c)  Except  as   required   by  law,   holders  of  Series  A
Participating  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 5. Certain Restrictions.

                  (a) The  Corporation  shall not declare any  dividend on, make
any   distribution   on,  or  redeem  or  purchase  or  otherwise   acquire  for
consideration  any shares of Common Stock after the first issuance of a share or
fraction  of  a  share  of  Series  A   Participating   Preferred  Stock  unless
concurrently therewith it shall declare a dividend on the Series A Participating
Preferred Stock as required by Section 3 hereof.

                  (b)  Whenever  quarterly   dividends  or  other  dividends  or
distributions payable on the Series A Participating  Preferred Stock as provided
in  Section  2 are in  arrears,  thereafter  and until all  accrued  and  unpaid
dividends  and  distributions,  whether or not  declared,  on shares of Series A
Participating  Preferred  Stock  outstanding  shall have been paid in full,  the
Corporation shall not:

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

                                   (ii)  declare or pay  dividends  on, 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  Series  A
Participating  Preferred  Stock,  except  dividends paid ratably on the Series A
Participating  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  on a  parity  (either  as to
dividends  or upon  liquidation,  dissolution  or winding  up) with the Series A
Participating  Preferred  Stock,  provided that the  Corporation may at any time
redeem,  purchase  or  otherwise  acquire  shares  of any such  parity  stock in
exchange for shares of any stock of the

<PAGE>



Corporation  ranking  junior  (either  as  to  dividends  or  upon  dissolution,
liquidation or winding up) to the Series A Participating Preferred Stock;

                                    (iv)  purchase  or  otherwise   acquire  for
consideration  any  shares of Series A  Participating  Preferred  Stock,  or any
shares of stock  ranking on a parity with the Series A  Participating  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.

                  (c) 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 5,  purchase or  otherwise  acquire such shares at such time and in
such manner.

         Section 6.  Reacquired  Shares.  Any  shares of Series A  Participating
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 to be  created by  resolution  or  resolutions  of the Board of
Directors,  subject to the  conditions  and  restrictions  on issuance set forth
herein and, in the Restated Certificate of Incorporation, as then amended.

to any  accrued  and  unpaid  dividends  on  such  shares  of  Series  A  Junior
Participating Preferred Stock.

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 the shares of
Series A  Participating  Preferred  Stock  shall at the same  time be  similarly
exchanged  or changed in an amount per share equal to 1,000 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.

         Section  9.  No  Redemption.  The  shares  of  Series  A  Participating
Preferred Stock shall not be redeemable.

         Section 10. Ranking.  The Series A Participating  Preferred Stock shall
rank junior to all other series of the  Corporation's  Preferred Stock as to the
payment of dividends  and the  distribution  of assets,  unless the terms of any
such series shall provide otherwise.

         Section 11. Amendment. The Restated Certificate of Incorporation of the
Corporation  shall not be further  amended in any manner which would  materially
alter or change  the  powers,  preference  or  special  rights  of the  Series A
Participating  Preferred  Stock  so as to  affect  them  adversely  without  the
affirmative  vote of the  holders of a  majority  of the  outstanding  shares of
Series A Participating Preferred Stock, voting separately as a class.

         Section 12. Fractional Shares.  Series A Participating  Preferred Stock
may be issued in  fractions  of a share  which  shall  entitle  the  holder,  in
proportion  to such  holder's  fractional  shares,  to exercise  voting  rights,
receive  dividends,  participate in distributions and to have the benefit of all
other rights of holders of Series A Participating Preferred Stock.




         RESOLVED   FURTHER:   That   1,000,000   shares   of  Series  A  Junior
         Participating  Preferred  Stock be, and they hereby are,  reserved  for
         issuance  upon  exercise  of the  Rights,  such number to be subject to
         adjustment from time to time in accordance with the Rights Agreement.

         RESOLVED FURTHER:  That the appropriate officers of the Company be, and
         they hereby are, authorized and directed to prepare and file an Amended
         and Restated  Certificate  of Designation  of Rights,  Preferences  and
         Privileges  in  accordance  with  the  foregoing  resolutions  and  the
         provisions  of Delaware  law and to take such  actions as they may deem
         necessary  or  appropriate  to carry out the  intent  of the  foregoing
         resolutions."

further  declare  under  penalty of perjury  that the  matters  set forth in the
foregoing  Amended and Restated  Certificate of Designation are true and correct

                                           the  Rights  holders  on or  prior to
                                           Distribution  Date;  thereafter,  the
                                           terms of the  Rights  and the  Rights

                                           order to cure any  ambiguities  or to
                                           make changes  which do not  adversely
                                           affect   the   interests   of  Rights
                                           holders  (other  than  the  Acquiring
                                           Person).                             

Voting Rights:                             Rights   will  not  have  any  voting
                                           rights.

Anti-Dilution                              Rights   will  have  the  benefit  of
Provisions:                                certain    customary    anti-dilution
                                           provisions.                          
                                           
Taxes:                                     The Rights distribution should not be
                                           taxable   for   federal   income  tax
                                           purposes. However, following an event
                                           which renders the Rights  exercisable
                                           or  upon  redemption  of the  Rights,
                                           stockholders  may  recognize  taxable
                                           income.

The foregoing is a summary of certain principal terms of the Stockholder  Rights
Plan only and is qualified in its entirety by reference to the detailed terms of
the Rights  Agreement  dated as of June 24,  1998,  between  the Company and the
Rights Agent.
