     WHEREAS,  the Board of Directors of the Company  authorized  and declared a

Senior  Convertible  Preferred  Stock,  par value $.10 per share, of the Company
(the "Senior Preferred Stock")  outstanding on the Record Date of that number of
Rights (the "As Converted Number of Rights") which would have been received by a
holder  of one  Share of  Series A Senior  Convertible  Preferred  Stock  had he

     NOW, THEREFORE,  in consideration of the premises 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  (as  such  term is
     hereinafter  defined) who or which,  together with all  Affiliates (as such
     term is  hereinafter  defined) and  Associates (as such term is hereinafter
     defined)  of such  Person,  without  the  prior  approval  of the  Board of
     Directors of the Company,  shall be the Beneficial Owner of shares of stock
     of the Company  having 15% or more of the voting  power of all Voting Stock
     (as such term is  hereinafter  defined) then  outstanding or who was such a
     Beneficial  Owner at any time  after the date  hereof,  whether or not such
     Person continues to be the Beneficial Owner of shares having 15% or more of
     the voting power of all outstanding  shares of Voting Stock,  but shall not
     include  the  Company,  any  subsidiary  of the  Company  (as such  term is
     hereinafter  defined),  any employee  benefit plan of the Company or any of
     its  subsidiaries  or any entity holding shares of Common Stock  organized,
     appointed or established by the Company or any of its  subsidiaries  for or
     pursuant to the terms of any such plan or any trustee or  administrator  of
     any such plan;  provided,  however,  that no Person  shall be an  Acquiring
     Person if within three  Business  Days after such Person would (but for the
     operation of this proviso) otherwise have become an Acquiring Person or, if
     such Person did so inadvertently, after such Person discovers that it would
     otherwise have become an Acquiring  Person if such Person both (i) notifies
     the Board of Directors  of the Company  that such Person would  (absent the
     operation of this  proviso) have become an Acquiring  Person  inadvertently
     and (ii) within three  Business Days after such  notification,  such Person
     divests  itself of a  sufficient  number of shares of Voting  Stock so that
     such Person is no longer the Beneficial Owner of shares of stock having 15%
     or more of the voting power of all  outstanding  shares of Voting Stock. In
     addition, none of the stockholders party to the Second Amended and Restated
     Shareholders Agreement,  dated as of July 30, 1999, between the Company and
     certain stockholders of the Company (the "Shareholders Agreement"), and the
     Related  Persons  (as  defined  in  the  Shareholders  Agreement)  of  such
     stockholders  shall  be an  Acquiring  Person  as a  result  of  being  the
     Beneficial Ownership of Voting Stock owned as of the date of this Agreement
     or hereafter acquired in compliance with the provisions of the Shareholders
     Agreement,  as it may be  validly  amended  from  time to  time  hereafter;
     provided,  however,  that  acquisitions  of Voting Stock by such Persons in
     excess  of  that  permitted  by the  Shareholders  Agreement  (as it may be
     validly  amended from time to time) will result in such Person  becoming an
     Acquiring  Person if such Person is then the Beneficial  Owner of shares of
     stock having 15% or more of the voting power of all  outstanding  shares of
     Voting  Stock;  provided,  however,  that if such Person would (but for the
     operation of this proviso) have become an Acquiring  Person  inadvertently,
     and if such Person both  notifies  the Board of Directors of the Company of
     its  inadvertence  within three  Business Days after such Person would have
     otherwise  become an Acquiring  Person and within three Business Days after
     such notification  divests itself of the Voting Stock acquired in violation
     of the  Shareholders  Agreement,  then  such  Person  shall  not  become an
     Acquiring Person.

<PAGE>


          be deemed  also to be  certificates  for  Rights)  and not by separate
          certificates,   and  (y)  the   Rights   (and  the  right  to  receive
          certificates  therefor) will be  transferable  only in connection with
          the  transfer  of the  underlying  shares of Common  Stock and  Senior

          however, that if a tender or exchange offer is terminated prior to the
          occurrence of the Distribution  Date, then no Distribution  Date shall

          the  Common  Stock and the Senior  Preferred  Stock as of the close of

          substantially   the   form  of   Exhibit   B   hereto   (the   "Rights
          Certificates"), evidencing one Right for each share of Common Stock so
          held and the As  Converted  Number of Rights  for each share of Senior

          Rights will be evidenced solely by such Rights Certificates.

               (b) With  respect to  certificates  for the Common  Stock and the
          Senior  Preferred Stock  outstanding as of the date of this Agreement,
          until the  Distribution  Date (or earlier  redemption,  expiration  or
          termination  of the  Rights),  the Rights  will be  evidenced  by such
          certificates  for the Common Stock and the  registered  holders of the
          Common  Stock  and  the  Senior  Preferred  Stock  shall  also  be the
          registered  holders of the associated  Rights.  Until the Distribution

<PAGE>

          Date (or earlier redemption, expiration or termination of the Rights),
          the surrender for transfer of any of the  certificates  for the Common
          Stock and the Senior  Preferred  Stock  outstanding on the Record Date
          shall also  constitute the transfer of the Rights  associated with the
          Common  Stock  and the  Senior  Preferred  Stock  represented  by such
          certificate.  Upon the  request  of the holder of any shares of Common
          Stock and the Senior Preferred Stock or, after the Distribution  Date,
          the holder of any Rights, the Company shall, at its expense, provide a
          copy of the Summary of Rights in the form  attached  hereto as Exhibit
          C.

               (c)  Certificates  for the Common Stock and the Senior  Preferred
          Stock  issued  (or which  become  outstanding)  after the date of this
          Agreement (or as soon  thereafter as is reasonably  practicable),  but
          prior to the earlier of the  Distribution  Date or the Expiration Date
          (as such term is  hereinafter  defined),  shall be  deemed  also to be
          certificates for Rights, and shall have impressed,  printed,  stamped,
          written or otherwise affixed onto them the following legend:

This certificate also evidences and entitles the holder hereof to certain Rights
as set forth in an Amended and Restated  Rights  Agreement  between Allied Waste
Industries,  Inc.  and  American  Stock  Transfer & Trust  Company  (the "Rights
Agent")  dated as of May 25, 2000 (the "Rights  Agreement"),  the terms of which
are hereby  incorporated  herein by reference  and a copy of which is on file at
the  principal  offices  of  Allied  Waste   Industries,   Inc..  Under  certain
circumstances,  as set  forth  in  the  Rights  Agreement,  such  Rights  may be
redeemed,  may expire, or may be evidenced by separate  certificates and will no
longer be evidenced by this certificate. Allied Waste Industries, Inc. will mail
to the holder of this certificate a copy of the Rights Agreement  without charge
within fifteen days after receipt of a written request  therefor.  Under certain
circumstances,  Rights  issued to  Acquiring  Persons  (as defined in the Rights
Agreement) or certain related  persons and any subsequent  holder of such Rights
may become null and void.

With respect to such  certificates  containing the foregoing  legend,  until the
Distribution  Date, the Rights  associated  with the Common Stock and the Senior


                                       8
<PAGE>

Preferred  Stock  represented  by such  certificates  shall be evidenced by such
certificates  alone, and the surrender for transfer of any of such  certificates
shall also  constitute  the  transfer of the Rights  associated  with the Common
Stock or the Senior  Preferred  Stock  represented by such  certificate.  If the
Company  purchases  or  otherwise  acquires  shares  of  Common  Stock or Senior
Preferred Stock prior to the Distribution  Date, any Rights associated with such
Common Stock or Senior  Preferred  Stock shall be deemed canceled and retired so
that the Company shall not be entitled to exercise any Right associated with the
shares  of  Common  Stock  or  Senior   Preferred  Stock  which  are  no  longer
outstanding.

     Section 4. Form of Rights Certificates.

               (a) The  Rights  Certificates  (and  the  forms  of  election  to
          purchase  shares  and of  assignment  to be  printed  on  the  reverse
          thereof) shall each be  substantially in the form set forth in Exhibit
          B hereto and may have such marks of  identification or designation and
          such legends, summaries or endorsements printed thereon as the Company
          may deem appropriate and as are not  inconsistent  with the provisions
          of this Agreement, or as may be required to comply with any applicable
          law or with any rule or regulation  made pursuant  thereto or with any
          rule or regulation of any stock  exchange on which the Rights may from
          time to  time be  listed,  or to  conform  to  usage.  Subject  to the
          provisions   of  Section  11  and   Section  23  hereof,   the  Rights
          Certificates,  whenever  distributed,  on their face shall entitle the
          holders  thereof to purchase such number of one  ten-thousandths  of a
          share of  Preferred  Stock as shall be set forth  therein at the price
          per share set forth therein (the "Purchase Price"),  but the number of
          such shares and the Purchase  Price shall be subject to  adjustment as
          provided herein.

               (b) Any Rights  Certificate  issued  pursuant to Section  3(a) or
          Section 23 hereof  that  represents  Rights  beneficially  owned by an
          Acquiring Person or any Associate or Affiliate  thereof and any Rights


                                       9
<PAGE>

          Certificate issued at any time upon the transfer of any Rights to such
          an Acquiring  Person or any  Associate or Affiliate  thereof or to any
          nominee of such  Acquiring  Person,  Associate or  Affiliate,  and any
          Rights  Certificate  issued  pursuant  to Section 6 or Section 11 upon
          transfer,  exchange,  replacement  or  adjustment  of any other Rights
          Certificate referred to in this sentence,  shall contain the following
          legend:

The Rights  represented by this Rights  Certificate  were issued to a Person who
was an Acquiring  Person or an Affiliate or an Associate of an Acquiring  Person
(as such terms are defined in the Rights  Agreement).  Accordingly,  this Rights
Certificate and the Rights represented hereby are null and void.

The  provisions  of Section  7(e) of this Rights  Agreement  shall be  operative
whether or not the foregoing legend is contained on any such Rights Certificate.

     Section 5. Countersignature and Registration. The Rights Certificates shall
be  executed on behalf of the  Company by its  Chairman  of the Board,  any Vice
Chairman of the Board,  any President or any Vice President,  either manually or
by facsimile  signature,  and shall have affixed thereto the Company's seal or a
facsimile  thereof  which  shall be attested by the  Secretary  or an  Assistant
Secretary of the Company, either manually or by facsimile signature.  The Rights
Certificates  shall be manually  countersigned by the Rights Agent and shall not
be valid for any  purpose  unless so  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  had not ceased to be such officer of the Company;  and any
Rights Certificates 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.

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  certificate

     Section  6.  Transfer,   Split  Up,  Combination  and  Exchange  of  Rights
Certificates;  Mutilated, Destroyed, Lost or Stolen Rights Certificates. Subject
to the  provisions of Section 4(b),  Section 7(e) and Section 15 hereof,  at any

the  close of  business  on the  Expiration  Date,  any  Rights  Certificate  or
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  ten-thousandths  of a share of Preferred Stock 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  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
principal  office  of  the  Rights  Agent.  Thereupon  the  Rights  Agent  shall
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.

     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 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 execute and deliver a new Rights Certificate of like
tenor to the Rights Agent for  countersignature  and delivery to the  registered
owner in lieu of the Rights Certificate so lost, stolen, destroyed or mutilated.

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

               (a) 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  upon
          presentation of the Rights  Certificate,  with the appropriate form of
          election to purchase on the reverse side thereof duly executed, to the
          Rights Agent at the  principal  office of the Rights  Agent,  together
          with payment of the Purchase  Price for each one  ten-thousandth  of a
          share of  Preferred  Stock  (or such  other  number of shares or other
          securities) as to which the Rights are  exercised,  at or prior to the
          earlier  of (i) the close of  business  on May 31,  2010  (the  "Final
          Expiration  Date"),  or (ii) the time at which the Rights are redeemed
          as  provided  in Section 24 hereof  (such  earlier  time being  herein
          referred  to as the  "Expiration  Date").  Notwithstanding  any  other
          provision of this Agreement,  any Person who prior to the Distribution
          Date  becomes a record  holder  of  shares  of Common  Stock or Senior
          Preferred Stock may exercise all of the rights of a registered  holder
          of a Rights  Certificate  with respect to the Rights  associated  with
          such shares of Common Stock or Senior  Preferred  Stock in  accordance
          with and subject to the  provisions of this  Agreement,  including the
          provisions  of Sections  4(b), 6 and 7(e) hereof,  as of the date such
          Person  becomes a record  holder  of shares of Common  Stock or Senior
          Preferred Stock.

               (b) Subject to the terms and  conditions  set forth herein,  when
          exercisable,  each Right shall  represent  the right to  purchase  one
          ten-thousandth  of a share of Preferred  Stock. The Purchase Price for
          each one  ten-thousandth of a share of Preferred Stock pursuant to the
          exercise  of a Right  shall  initially  be $85,  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  appropriate  form of  election  to  purchase  duly
          executed,  accompanied by payment of the Purchase Price for the shares
          (or other  securities or property) to be purchased and an amount equal
          to any applicable  transfer tax (as determined by the Rights Agent) in
          cash, or by certified  check or bank draft payable to the order of the
          Company, the Rights Agent shall,  subject to Section 21(k),  thereupon
          promptly (i) (A) requisition  from any transfer agent of the shares of
          Preferred  Stock  (or  make  available,  if the  Rights  Agent  is the
          transfer  agent)  certificates  for the number of shares of  Preferred
          Stock to be purchased and the Company  hereby  irrevocably  authorizes
          its  transfer  agent to comply with all such  requests,  or (B) if the
          Company,  in its sole  discretion,  shall have  elected to deposit the
          shares  of  Preferred  Stock  issuable  upon  exercise  of the  Rights
          hereunder into a depositary,  requisition  from the  depositary  agent
          depositary receipts  representing such number of one ten-thousandth of
          a share of  Preferred  Stock as are to be  purchased  (in  which  case
          certificates  for the shares of Preferred  Stock  represented  by such
          receipts  shall be deposited by the transfer agent with the depositary
          agent) and the Company will direct the depositary agent to comply with
          such request, (ii) when appropriate,  requisition from the Company the
          amount of cash,  if any, to be paid in lieu of issuance of  fractional
          shares in accordance  with Section l5, (iii) promptly after receipt of


                                       13
<PAGE>

          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 promptly deliver
          such cash to or upon the order of the registered holder of such Rights
          Certificate. In the event that the Company is obligated to issue other
          securities (including Common Stock) of the Company,  and/or distribute
          other property  pursuant to Section  11(a),  the Company will make all
          arrangements  necessary so that such other securities  and/or property
          are  available  for  distribution  by the  Rights  Agent,  if and when
          appropriate.  In addition, in the case of an exercise of the Rights by
          a holder pursuant to Section 11(a)(ii),  the Rights Agent shall return
          such  Rights  Certificate  to  the  registered  holder  thereof  after
          imprinting,  stamping or otherwise  indicating thereon that the rights
          represented  by such Rights  Certificate  no longer include the rights
          provided by Section 11(a)(ii) of the Rights Agreement and if less than
          all  the  Rights  represented  by  such  Rights  Certificate  were  so
          exercised,  the Rights Agent shall indicate on the Rights  Certificate
          the number of Rights represented thereby which continue to include the
          rights provided by Section 11(a)(ii).

               (d) In case the registered holder of any Rights Certificate shall
          exercise  (except  pursuant  to Section  11(a)(ii))  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 and  delivered to the  registered  holder of such Rights
          Certificate  or  to  his  duly  authorized  assigns,  subject  to  the
          provisions of Section l5 hereof.

               (e)  Notwithstanding  anything in this Agreement to the contrary,
          from and after the time an Acquiring  Person first becomes  such,  any
          Rights  beneficially  owned by (i) an Acquiring Person or an Affiliate
          or Associate of an Acquiring Person, (ii) a transferee of an Acquiring
          Person  (or of any  Affiliate  or  Associate  thereof)  who  becomes a
          transferee  after  the  Acquiring  Person  becomes  such,  or  (iii) a


                                       14
<PAGE>

          transferee  of an Acquiring  Person (or of any  Affiliate or Associate
          thereof) 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 a
          continuing  agreement,  arrangement  or  understanding  regarding  the
          transferred  Rights or (B) a transfer  which the Board of Directors of
          the  Corporation  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),  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  Corporation  shall use all  reasonable
          efforts to insure 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 Right  Certificates  or  other  Person  as a result  of its
          failure to make any determinations with respect to an Acquiring Person
          or its 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 the certificate  contained in the appropriate  form of election
          to purchase  set forth on the reverse  side of the Rights  Certificate
          surrendered  for such exercise shall have been completed and signed by
          the registered holder thereof and the Company shall have been provided
          with 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,


                                       15
<PAGE>

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

     Section 9.  Reservation and  Availability of Preferred  Stock.  The Company
covenants and agrees that it will cause to be reserved and kept available out of
its authorized  and unissued  shares of Preferred  Stock,  or any authorized and
issued shares of Preferred  Stock held in its treasury,  the number of shares of
Preferred  Stock that will be  sufficient  to permit the exercise in full of all
outstanding  Rights and, after the  occurrence of an event  specified in Section
11,  shall so  reserve  and keep  available  a  sufficient  number  of shares of
Preferred  Stock (and/or other  securities)  which may be required to permit the
exercise in full of the Rights pursuant to this Agreement.

     So long as the shares of Preferred  Stock (and,  after the occurrence of an
event specified in Section 11, any other securities)  issuable upon the exercise
of the Rights may be listed on any  national  securities  exchange,  the Company
shall use its best  efforts  to cause,  from and after  such time as the  Rights
become exercisable,  all shares (or other securities) reserved for such issuance
to be  listed on such  exchange  upon  official  notice  of  issuance  upon such
exercise.

     The Company  covenants  and agrees that it will take all such action as may
be necessary to ensure that all shares of Preferred  Stock,  Common Stock and/or


                                       16
<PAGE>

other  securities  delivered  upon  exercise  of  Rights  shall,  at the time of
delivery of the  certificates  for such shares or other  securities  (subject to
payment of the Purchase Price), be duly and validly authorized and
issued and fully paid and nonassessable shares or securities.

     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 issuance or delivery of the Rights  Certificates or of
any  certificates  for shares of  Preferred  Stock,  Common  Stock  and/or other
securities  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 in respect of the
issuance or delivery of the shares of Preferred Stock, Common Stock and/or other
securities  in a name other than that of,  the  registered  holder of the Rights
Certificates  evidencing Rights  surrendered for exercise or to issue or deliver
any  certificates  for shares of  Preferred  Stock,  Common  Stock  and/or other
securities in a name other than that of the registered  holder upon the exercise
of any Rights until such tax shall have been paid (any such tax being payable by
the holder of such Rights  Certificate at the time of surrender) or until it has
been established to the Company's satisfaction that no such tax is due.

     The Company shall use its best efforts to (i) file, as soon as  practicable
following the Distribution  Date, a registration  statement under the Securities
Act of 1933  (the  "Act"),  with  respect  to the  securities  purchasable  upon
exercise  of the Rights on an  appropriate  form,  (ii) cause such  registration
statement to become  effective  as soon as  practicable  after such filing,  and
(iii) cause such  registration  statement to remain effective (with a prospectus
at all  times  meeting  the  requirements  of the  Act)  until  the  date of the
expiration of the rights  provided by Section  11(a)(ii).  The Company will also
take such  action as may be  appropriate  under the blue sky laws of the various
states.

                                       17

     Section 10.  Preferred  Stock  Record  Date.  Each person in whose name any
certificate  for  shares  of  Preferred  Stock (or  Common  Stock  and/or  other
securities)  is issued  upon the  exercise of Rights  shall for all  purposes be
deemed to have become the holder of record of the shares of Preferred  Stock (or
Common  Stock  and/or  other  securities)   represented  thereby  on,  and  such
certificate  shall  be  dated,  the  date  upon  which  the  Rights  Certificate
evidencing such Rights was duly presented and payment of the Purchase Price (and
any applicable transfer taxes) was made; provided,  however, that if the date of
such  presentation  and  payment  is a date upon which the  Preferred  Stock (or
Common Stock and/or other securities)  transfer books of the Company are closed,
such person shall be deemed to have become the record  holder of such shares on,
and such certificate  shall be dated, the next succeeding  Business Day on which
the Preferred Stock (or Common Stock and/or other securities)  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
stockholder  of the Company with respect to shares 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 Purchase  Price,  Number and Kind of Shares or
Number of Rights.  The Purchase Price,  the number and kind of shares covered by
each Right and the number of Rights outstanding are subject to
adjustment from time to time as provided in this Section 11.

               (a) (i) In the event the Company shall at any time after the date
          of this  Agreement  (A)  declare a  dividend  on the  Preferred  Stock
          payable in shares or  fractional  units of shares of Preferred  Stock,
          (B)  subdivide  the  outstanding  Preferred  Stock,  (C)  combine  the


                                       18
<PAGE>

          outstanding  Preferred  Stock  into a smaller  number of shares or (D)
          issue any shares of its  capital  stock in a  reclassification  of the
          Preferred  Stock  (including any such  reclassification  in connection
          with a consolidation  or merger in which the Company is the continuing
          or  surviving  corporation),  except  as  otherwise  provided  in this
          Section  11(a),  and Section 7(e), the Purchase Price in effect at the
          time of the record date for such dividend or of the effective  date of
          such subdivision,  combination or reclassification,  and the number of
          units of one  ten-thousandths  of a share of  Preferred  Stock and the
          number and kind of shares of capital stock  issuable on such date upon
          exercise  of a Right,  shall be  proportionately  adjusted so that the
          holder of any Right  exercised  after such time shall be  entitled  to
          receive  the  aggregate  number of units of one  ten-thousandths  of a
          share of Preferred  Stock and the number and kind of shares of capital
          stock and other  securities  which,  if such Right had been  exercised
          immediately  prior to such date and at a time when the Preferred Stock
          transfer books of the Company were open, he would have owned upon such
          exercise  and been  entitled  to receive  by virtue of such  dividend,
          subdivision, combination or reclassification;  provided, however, that
          in no event shall the  consideration  to be paid upon  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. If an event
          occurs which would require an adjustment  under both Section  11(a)(i)
          and Section  11(a)(ii),  the  adjustment  provided for in this Section
          11(a)(i)  shall be in  addition  to,  and  shall be made  prior to any
          adjustment required pursuant to Section 11(a)(ii).

                    (ii) In the event any  Person,  alone or  together  with its
               Affiliates and Associates, shall become an Acquiring Person, then


                                       19
<PAGE>

               proper  provision  shall be made so that each  holder of a Right,
               except as provided in Section 7(e) hereof, shall, for a period of
               60 days (or such other  longer  period as may be  established  by
               action of a majority of the Board of  Directors)  after the later
               of the  occurrence of any such event and the effective date of an
               appropriate  registration statement pursuant to Section 9, have a
               right to  receive,  upon  exercise  thereof  at the then  current
               Purchase  Price in accordance  with the terms of this  Agreement,
               such  number of one  ten-thousandths  of shares of the  Preferred
               Stock as shall equal the result  obtained by (x)  multiplying the
               then   current   Purchase   Price  by  the  then  number  of  one
               ten-thousandths  of a share of Preferred  Stock for which a Right
               is exercisable  immediately prior to the first occurrence of such
               event and dividing that product by (y) 50% of the current  market
               price per one  two-thousandths  of a share of the Preferred Stock
               (determined  pursuant to Section 11(d)) on the date of such first
               occurrence (such number of one  ten-thousandths  of a share being
               referred to as the "number of Adjustment Shares").

                    (iii)  In the  event  that  there  shall  not be  sufficient
               authorized but unissued  shares of Preferred  Stock to permit the
               exercise in full of the Rights in  accordance  with the foregoing
               subparagraph  (ii),  then,  in the  event  the  Rights  become so
               exercisable,   notwithstanding   any  other   provision  of  this
               Agreement,  to the extent  necessary  and permitted by applicable
               law and any  agreements  in effect on the date hereof to which it
               is a party,  each Right shall  thereafter  represent the right to
               receive, upon exercise thereof at the then current Purchase Price
               in  accordance  with the  terms of this  Agreement,  a number  of


                                       20
<PAGE>

               shares of Common Stock equal to the number of  Adjustment  Shares
               or a number of shares,  or units of shares,  of  preferred  stock
               equal to the  number  of  Adjustment  Shares  where  the Board of
               Directors  of the Company  shall have deemed such shares or units
               to have at least the same or more  favorable  rights,  privileges
               and preferences as the Preferred Stock (an "equivalent  preferred
               stock") or a combination  of Preferred  Stock and/or Common Stock
               and/or  equivalent  preferred stock having the requisite value as
               determined by the the Board of Directors;  provided,  however, if
               there are unavailable sufficient shares of Preferred Stock and/or
               Common Stock and/or equivalent  preferred stock, then the Company
               shall  take all such  action  as may be  necessary  to  authorize
               additional shares of Preferred Stock and/or equivalent  preferred
               stock and/or shares of Common Stock for issuance upon exercise of
               the Rights,  including the calling of or meeting of shareholders;
               and  provided,  further,  that if the  Company is unable to cause
               sufficient shares of Preferred Stock and/or equivalent  preferred
               stock and/or  shares of Common Stock to be available for issuance
               upon  exercise  in full of the  Rights,  then  each  Right  shall
               thereafter  represent the right to receive the Adjusted Number of
               Preferred Shares upon exercise at the Adjusted Purchase Price (as
               such terms are  hereinafter  defined.) As used  herein,  the term
               Adjusted Number of Preferred Shares shall be equal to that number
               of one  ten-thousandths  of a share of  Preferred  Stock  (and/or
               shares or units of  equivalent  preferred  stock and/or shares of
               Common  Stock)  equal  to  the  product  of  (x)  the  number  of
               Adjustment  Shares and (y) a fraction,  the numerator of which is
               the number of one  ten-thousandths  of a share of Preferred Stock
               (and/or  shares or units of  equivalent  preferred  stock  and/or
               shares of Common  Stock)  available for issuance upon exercise of
               the Rights and the  denominator of which is the aggregate  number
               of Adjustment Shares otherwise  issuable upon exercise in full of
               all Rights  (assuming there were  sufficient  shares of Preferred


                                       21
<PAGE>

               Stock   available)  (such  fraction  being  referred  to  as  the
               "Proration  Factor").  The Adjusted Purchase Price shall mean the
               product of the Purchase Price and the Proration Factor. The Board
               of  Directors  may,  but  shall  not be  required  to,  establish
               procedures  to  allocate  the right to receive  Preferred  Stock,
               equivalent  preferred  stock  and  shares of  Common  Stock  upon
               exercise of the Rights among holders of Rights.

               (b) If the Company  shall fix a record  date for the  issuance of
          rights,  options  or  warrants  to  all  holders  of  Preferred  Stock
          entitling  them (for a period  expiring  within 45 calendar days after
          such record date) to  subscribe  for or purchase  Preferred  Stock (or
          equivalent  preferred stock or securities  convertible  into Preferred
          Stock or equivalent preferred stock) at a price per share of Preferred
          Stock  or per  share  of  equivalent  preferred  stock  (or  having  a
          conversion  price per share, if a security  convertible into Preferred
          Stock or  equivalent  preferred  stock) less than the  current  market
          price (as  defined in Section  11(d) per share of  Preferred  Stock on
          such record date, the Purchase Price to be in effect after such record
          date shall be determined by  multiplying  the Purchase Price in effect
          immediately prior to such record date by a fraction,  the numerator of
          which shall be the number of shares of Preferred Stock  outstanding on
          such record date,  plus the number of shares of Preferred  Stock which
          the  aggregate  offering  price  of the  total  number  of  shares  of
          Preferred  Stock  and/or  equivalent  preferred  stock  to be  offered
          (and/or the  aggregate  initial  conversion  price of the  convertible
          securities  so to be offered)  would  purchase at such current  market
          price and the  denominator  of which  shall be the number of shares of
          Preferred  Stock  outstanding on such record date,  plus the number of
          additional shares of Preferred Stock and/or equivalent preferred stock
          to be  offered  for  subscription  or  purchase  (or  into  which  the
          convertible  securities so to be offered are  initially  convertible);
          provided, however, that in no event shall the consideration to be paid


                                       22
<PAGE>

          upon 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 determined  reasonably and with good faith
          to the  holders of Rights by the Board of  Directors  of the  Company,
          whose  determination  shall be described in a statement filed with the
          Rights  Agent and shall be  binding  on the  Rights  Agent.  Shares of
          Preferred  Stock 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 or  warrants  are not so
          issued,  the Purchase Price shall be adjusted to be the Purchase Price
          which would then be in effect if such record date had not been fixed.

               (c) If the  Company  shall fix a record  date for the making of a
          distribution  to all holders of Preferred  Stock  (including  any such
          distribution  made in  connection  with a  consolidation  or merger in
          which the  Company is the  continuing  corporation)  of  evidences  of
          indebtedness,  cash (other than a regular  quarterly cash dividend out
          of the earnings or retained  earnings of the  Company),  assets (other
          than a dividend payable in Preferred Stock, but including any dividend
          payable in stock other than Preferred Stock) or subscription rights or
          warrants  (excluding those referred to in Section 11(b)), the Purchase
          Price to be in effect  after such record date shall be  determined  by
          multiplying  the Purchase  Price in effect  immediately  prior to such
          record date by a fraction, the numerator of which shall be the current
          market  price (as  defined  in Section  11(d)) per share of  Preferred
          Stock on such record date,  less the fair market value (as  determined
          reasonably  and with good faith to the  holders of Rights by the Board
          of Directors of the Company, whose determination shall be described in
          a  statement  filed with the Rights  Agent and shall be binding on the
          Rights  Agent) of the  portion  of the cash,  assets or  evidences  of


                                       23
<PAGE>

          indebtedness  so to be distributed or of such  subscription  rights or
          warrants  distributable in respect of one share of Preferred Stock and
          the  denominator  of which shall be current  market price per share of
          the Preferred  Stock;  provided,  however,  that in no event shall the
          consideration  to be paid upon  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 Purchase Price shall again
          be adjusted to be the Purchase  Price which would be in effect if such
          record date had not been fixed.

               (d) (i) For the purpose of any computation hereunder,  other than
          in Section 11(a)(iii),  the "current market price" per share of Common
          Stock on any date  shall be  deemed  to be the  average  of the  daily
          closing  prices per share of such Common Stock for the 30  consecutive
          Trading Days (as such term is hereinafter  defined)  immediately prior
          to such date;  provided,  however,  that in the event that the current
          per share  market  price of the Common  Stock is  determined  during a
          period  following the  announcement by the issuer of such Common Stock
          of (A) a dividend  or  distribution  on such Common  Stock  payable in
          shares of such Common Stock or securities  convertible  into shares of
          such   Common   Stock   or  (B)  any   subdivision,   combination   or
          reclassification  of such Common Stock, and prior to the expiration of
          30  Trading  Days  after the  ex-dividend  date for such  dividend  or
          distribution, or the record date for such subdivision,  combination or
          reclassification,  then,  and in each such case,  the "current  market
          price"  shall be properly  adjusted to take into  account  ex-dividend
          trading.  The closing price for each day shall be the last sale price,
          regular  way,  or, in case no such sale takes  place on such day,  the
          average of the closing bid and asked  prices,  regular  way, in either
          case as reported in the principal  consolidated  transaction reporting
          system with respect to securities listed or admitted to trading on the
          New York  Stock  Exchange  or, if the  shares of Common  Stock are not


                                       24
<PAGE>

          listed or  admitted  to  trading on the New York  Stock  Exchange,  as
          reported in the principal  consolidated  transaction  reporting system
          with respect to securities listed on the principal national securities
          exchange on which the shares of Common Stock are listed or admitted to
          trading or, if the shares of Common Stock or not listed or admitted to
          trading on any national securities exchange, the last quoted price or,
          if not so quoted,  the average of the high bid and low asked prices in
          the  over-the-counter  market, as reported by the National Association
          of Securities  Dealers,  Inc. Automated Quotation System ("NASDAQ") or
          such other  system then in use,  or, if on any such date the shares of
          Common Stock are not quoted by any such  organization,  the average of
          the closing bid and asked prices as furnished by a professional market
          maker  making a market in the Common  Stock  selected  by the Board of
          Directors  of the  Company.  If on any such  date no  market  maker is
          making a market in the Common Stock,  the fair value of such shares on
          such date as determined reasonably and with good faith by the Board of
          Directors  of the  Company  shall be used and shall be  binding on the
          Rights  Agent.  The term,  "Trading Day" shall mean a day on which the
          principal national  securities  exchange on which the shares of Common
          Stock are listed or admitted to trading is open for the transaction of
          business  or, if the shares of Common Stock are not listed or admitted
          to trading on any national securities exchange, a Business Day. If the
          Common Stock is not publicly held or not so listed or traded, "current
          market price" per share shall mean the fair value per share determined
          reasonably  and with good faith to the  holders of Rights by the Board
          of Directors of the Company, whose determination shall be described in
          a  statement  filed with the Rights  Agent and shall be binding on the
          Rights Agent.

                    (ii)  For the  purpose  of any  computation  hereunder,  the
               "current  market  price" per share (or one  ten-thousandths  of a
               share)  of  Preferred  Stock  or  any  other  security  shall  be
               determined  in the same  manner as set forth above for the Common
               Stock in clause (i) of this  Section  11(d)  (other than the last
               sentence thereof).  If the current market price per share (or one


                                       25
<PAGE>

               ten-thousandths   of  a  share)  of  Preferred  Stock  cannot  be
               determined in the manner provided above or if the Preferred Stock
               is not publicly held or listed or traded in a manner described in
               clause (i) of this Section 11(d),  the "current market price" per
               share of Preferred  Stock shall be  conclusively  deemed to be an
               amount  equal to  10,000  (as such  number  may be  appropriately
               adjusted for such events as stock  splits,  stock  dividends  and
               recapitalizations  with  respect  to the Common  Stock  occurring
               after  the  date of this  Agreement)  multiplied  by the  current
               market  price per  share of the  Common  Stock  and the  "current
               market  price" per one  ten-thousandths  of a share of  Preferred
               Stock shall be equal to the current market price per share of the
               Common Stock (as appropriately  adjusted).  If neither the Common
               Stock nor the  Preferred  Stock is publicly  held or so listed or
               traded,  "current  market  price"  per share  shall mean the fair
               value  per  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  and  shall  be
               conclusive for all purposes.

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

               (f) If as a result of any  provision of Section  11(a) or Section
          13(a),  the  holder of any Right  thereafter  exercised  shall  become
          entitled to receive any shares of capital  stock of the Company  other
          than  Preferred  Stock,  thereafter the number of such other shares so
          receivable  upon  exercise of any Right shall be subject to adjustment
          from  time to time in a manner  and on terms as nearly  equivalent  as
          practicable to the provisions with respect to the shares  contained in
          Section 11(a) through (c),  inclusive,  and the provisions of Sections
          7, 9, 10, 13 and 15 hereof with respect to the  Preferred  Stock shall
          apply on like terms to any such other shares.

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

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

               (i) The Company may elect on or after the date of any  adjustment
          of the Purchase Price to adjust the number of Rights,  in substitution
          for  any  adjustment  in the  number  of  shares  of  Preferred  Stock


                                       27
<PAGE>

          purchasable  upon  the  exercise  of  a  Right.  Each  of  the  Rights
          outstanding  after the  adjustment  in the  number of Rights  shall be
          exercisable  for the  number  of one  ten-thousandths  of a  share  of
          Preferred Stock 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 ten-thousandth) obtained by dividing the Purchase Price in
          effect  immediately  prior to adjustment of the Purchase  Price by the
          Purchase Price in effect  immediately after adjustment of the Purchase
          Price. The Company shall make a public announcement of its election to
          adjust  the  number of  Rights,  indicating  the  record  date for the
          adjustment, and, if known at the time, the amount of the adjustment to
          be made.  This record date may be the date on which the Purchase Price
          is adjusted  or any day  thereafter,  but, if the Rights  Certificates
          have been issued, shall be at least 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(i),  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 15 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 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  Purchase  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.

               (j)  Irrespective  of any  adjustment  or change in the  Purchase
          Price or the  number  of one  ten-thousandth  of a share of  Preferred


                                       28
<PAGE>

          Stock   issuable   upon  the  exercise  of  the  Rights,   the  Rights
          Certificates theretofore and thereafter issued may continue to express
          the  Purchase  Price  per share and the  number of shares  which  were
          expressed in the initial Rights Certificates issued hereunder.

               (k)  Before  taking any action  that  would  cause an  adjustment
          reducing  the  Purchase  Price below the then stated or par value,  if
          any,  of  the  shares  of  Preferred  Stock,  Common  Stock  or  other
          securities  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
          fully paid and nonassessable  shares of Preferred Stock,  Common Stock
          or other securities at such adjusted Purchase Price.

               (l) In any case in which this  Section 11 shall  require  that an
          adjustment in the Purchase Price be made effective as of a record date
          for a  specified  event,  the  Company  may  elect to defer  until the
          occurrence  of such  event  the  issuing  to the  holder  of any Right
          exercised  after such  record date the shares of  Preferred  Stock and
          other capital stock or  securities  of the Company,  if any,  issuable
          upon such  exercise  over and above the shares of Preferred  Stock and
          other capital stock or  securities  of the Company,  if any,  issuable
          upon such exercise on the basis of the Purchase  Price in effect prior
          to such adjustment;  provided, however, that the Company shall deliver
          to such holder a due bill or other appropriate  instrument  evidencing
          such  holder's  right  to  receive  such  additional  shares  upon the
          occurrence of the event requiring such adjustment.

               (m) Anything to the contrary in this Section 11  notwithstanding,
          the Company, by action of a majority of the Board of Directors,  shall
          be entitled to make such reductions in the Purchase Price, in addition
          to those adjustments  expressly required by this Section 11, as and to
          the  extent  that it in its  sole  discretion  shall  determine  to be
          advisable  in  order  that any  consolidation  or  subdivision  of the
          Preferred  Stock,  issuance wholly for cash of any shares of Preferred
          Stock at less than the current market price,  issuance wholly for cash


                                       29
<PAGE>

          of shares of Preferred  Stock or  securities  which by their terms are
          convertible into or exchangeable for shares of Preferred Stock,  stock
          dividends  or  issuance  of rights,  options or  warrants  referred to
          hereinabove  in this  Section  11,  hereafter  made by the  Company to
          holders  of  its  Preferred   Stock  shall  not  be  taxable  to  such
          stockholders.

               (n) The  Company  covenants  and agrees that it shall not, at any
          time  after the  Distribution  Date,  (i)  consolidate  with any other
          Person (other than a subsidiary of the Company in a transaction  which
          does not violate  Section 11(o)  hereof),  (ii) merge with or into any
          other Person  (other than a subsidiary of the Company in a transaction
          which does not violate Section 11(o) hereof, or (iii) sell or transfer
          (or permit any subsidiary to sell or transfer), in one transaction, or
          a series of related transactions,  assets or earning power aggregating
          more than 50% 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  and/or  any of  its  subsidiaries  in one or  more
          transactions each of which does not violate Section 11(o) hereof),  if
          (x) at the time of or immediately  after such  consolidation,  merger,
          sale or  transfer  there are any charter or by-law  provisions  or any
          rights,  warrants or other  instruments  or securities  outstanding or
          agreements in effect or other actions  taken,  which would  materially
          diminish or otherwise  eliminate the benefits  intended to be afforded
          by the  Rights  or (y) prior to,  simultaneously  with or  immediately
          after such  consolidation,  merger or sale,  the  stockholders  of the
          Person who constitutes, or would constitute, the "Principal Party" for
          purposes of Section 13(a) hereof shall have received a distribution of
          Rights  previously  owned by such Person or any of its  Affiliates and
          Associates.  The Company shall not consummate any such  consolidation,
          merger,  sale or transfer  unless  prior  thereto the Company and such
          other Person shall have  executed and  delivered to the Rights Agent a
          certificate certifying compliance with this Section 11(n).

               (o) The Company covenants and agrees that, after the Distribution
          Date,  it will not,  except as  permitted  by Section 23 or Section 26
          hereof, take (or permit any subsidiary to take) any action the purpose
          of  which  is  to,  or if at the  time  such  action  is  taken  it is
          reasonably   foreseeable  that  the  effect  of  such  action  is  to,
          materially diminish or otherwise eliminate the benefits intended to be
          afforded by the Rights.

               (p) Anything in this  Agreement to the contrary  notwithstanding,
          in the event that the Company shall at any time after the date of this
          Agreement  and prior to the  Distribution  Date (i)  declare  or pay a
          dividend on the  outstanding  shares of Common Stock payable in shares
          of Common Stock,  (ii) subdivide the outstanding  Common Stock,  (iii)
          combine or  consolidate  the  outstanding  Common Stock into a smaller
          number of shares,  or (iv) issue any shares of its capital  stock in a
          reclassification  of the  outstanding  Common Stock,  then in any such
          case, the number of Rights  associated with each share of Common Stock
          then outstanding,  or issued or delivered  thereafter but prior to the
          Distribution  Date,  shall  be  proportionately  adjusted  so that the
          number of Rights thereafter associated with each share of Common Stock
          following   any  such  event  shall  equal  the  result   obtained  by
          multiplying the number of Rights  associated with each share of Common
          Stock  immediately  prior to such event by a fraction the numerator of
          which shall be the total number of shares of Common Stock  outstanding
          immediately  prior to the occurrence of the event and the  denominator
          of  which  shall  be the  total  number  of  shares  of  Common  Stock
          outstanding  immediately  following the occurrence of such event.  The
          adjustments   provided  for  in  this  Section  11(p)  shall  be  made
          successively  whenever  such a dividend  is declared or paid or such a
          subdivision,   combination,   consolidation  or   reclassification  is
          effected.

               (q) The exercise of Rights  under  Section  11(a)(ii)  shall only
          result in the loss of rights under Section  11(a)(ii) to the extent so


                                       31
<PAGE>

          exercised and shall not otherwise affect the rights represented by the
          Rights under this Rights Agreement,  including the rights  represented
          by Section 13.

     Section 12.  Certificate  of Adjusted  Purchase  Price or Number of Shares.
Whenever an  adjustment  is made as  provided in Sections 11 and 13 hereof,  the
Company shall (a) promptly  prepare a certificate  setting forth such adjustment
and a brief statement of the facts accounting for such adjustment,  (b) promptly
file with the Rights Agent and with each transfer agent for the Preferred  Stock
and the Common  Stock 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.  The  Rights  Agent  shall be fully  protected  in  relying  on any such
certificate and on any adjustment  therein  contained and shall not be deemed to
have knowledge of such  adjustment  unless and until it shall have received such
certificate.

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

               (a) In the event  that,  on or  following  the Stock  Acquisition
          Date, directly or indirectly,  (x) the Company shall consolidate with,
          or merge  with and  into,  any  other  Person,  (y) 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
          merger and, in connection with such merger,  all or part of the shares
          of Common Stock shall be changed into or exchanged  for stock or other
          securities  of any other  Person or cash or any other  property or all
          holders of shares of Common  Stock are not treated  alike or following
          the merger or  consolidation  the holders of Common Stock  immediately
          prior to the transaction do not hold in the same proportion all of the
          voting power of the corporation surviving the transaction,  or (z) the
          Company shall sell,  mortgage or otherwise transfer (or one or more of
          its subsidiaries shall sell, mortgage or otherwise  transfer),  in one
          or more  transactions,  assets or earning power  aggregating more than


                                       32
<PAGE>

          50% of the assets or earning power of the Company and its subsidiaries
          (taken as a whole) to any other Person,  then,  and in each such case,
          proper  provision shall be made so that (i) following the Distribution
          Date,  each holder of a Right,  shall have the right to receive,  upon
          the exercise  thereof at the then current Purchase Price in accordance
          with the  terms of this  Agreement,  such  number  of shares of freely
          tradeable   Common  Stock  of  the  Principal  Party  (as  hereinafter
          defined),  free and clear of liens,  rights of call or first  refusal,
          encumbrances or other adverse claims,  as shall be equal to the result
          obtained by (1)  multiplying  the then current  Purchase  Price by the
          number of one  ten-thousandths of a share of Preferred Stock for which
          a Right is then  exercisable  and dividing  that product by (2) 50% of
          the  current  market  price  per  share  of the  Common  Stock of such
          Principal Party  (determined  pursuant to Section 11(d) hereof) on the
          date of consummation of such consolidation,  merger, sale or transfer;
          (ii) such  Principal  Party shall  thereafter be liable for, and shall
          assume, by virtue of such consolidation,  merger sale or transfer, all
          the obligations and duties of the Company  pursuant to this Agreement;
          (iii) the term "Company"  shall  thereafter be deemed to refer to such
          Principal Party, it being specifically intended that the provisions of
          Section 11 hereof shall apply to such Principal  Party;  and (iv) such
          Principal Party shall take such steps (including,  but not limited to,
          the  reservation of a sufficient  number of shares of its Common Stock
          in  accordance   with  Section  9  hereof)  in  connection  with  such
          consummation as may be necessary to assure that the provisions  hereof
          shall  thereafter be  applicable,  as nearly as reasonably  may be, in
          relation to its shares of Common Stock thereafter deliverable upon the
          exercise of the Rights.

               (b) "Principal Party" shall mean

                    (i) in the case of any  transaction  described in (x) or (y)
               of the first  sentence of this Section 13, the Person that is the
               issuer of any securities into which shares of Common Stock of the


                                       33
<PAGE>

               Company are converted in such merger or consolidation,  and if no
               securities  are so issued,  the Person that is the other party to
               the  merger  or  consolidation  (including,  if  applicable,  the
               Company if it is the surviving corporation); and

                    (ii) in the case of any transaction  described in (z) of the
               first  sentence in this  Section 13, the Person that is the party
               receiving  the  greatest  portion of the assets or earning  power
               transferred pursuant to such transaction or transactions;

provided, however, that in any such case, (1) if the Common Stock of such Person
is not at such time and has not been  continuously  over the preceding  12-month
period  registered  under  Section 12 of the Exchange  Act, and such Person is a
direct or indirect subsidiary or Affiliate of another Person,  "Principal Party"
shall  refer to such  other  Person;  (2) in case such  Person is a  subsidiary,
directly or indirectly,  or Affiliate of more than one Person, the Common Stocks
of two or more of which are and have been so registered, "Principal Party" shall
refer to  whichever of such Persons is the issuer of the Common Stock having the
greatest aggregate market value; and (3) in case 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 (1)
and (2) above shall apply to each of the chains of ownership  having an interest
in such joint  venture as if such  party were a  "Subsidiary"  of both or all of
such joint venturers and the Principal Parties in each such chain shall bear the
obligations  set forth in this  Section 13 in the same ratio as their  direct or
indirect interests in such Person bear to the total of such interests.

               (c) The  Company  shall not  consummate  any such  consolidation,
          merger,  sale or transfer  unless  prior  thereto the Company and each
          Principal Party and each other Person who may become a Principal Party


                                       34
<PAGE>

          as a result of such consolidation, merger, sale or transfer shall have
          a  sufficient  number of shares of its  authorized  Common Stock which
          have not been issued or reserved  for  issuance in order to permit the
          exercise in full of the Rights in accordance  with this Section 13 and
          shall have executed and  delivered to the Rights Agent a  supplemental
          agreement  providing for the terms set forth in paragraphs (a) and (b)
          of this Section 13 and further  providing that, as soon as practicable
          after  the date of any  consolidation,  merger,  sale or  transfer  of
          assets  mentioned in paragraph  (a) of this Section 13, the  Principal
          Party at its own expense will

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

                    (ii) use its best  efforts to qualify or register the Rights
               and the securities  purchasable upon exercise of the Rights under
               the blue sky laws of such  jurisdictions  as may be  necessary or
               appropriate; and

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

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations  or sales or other  transfers.  The rights  under this Section 13
shall be in  addition  to the rights to exercise  Rights and  adjustments  under
Section 11(a)(ii) and shall survive any exercise thereunder.

     Section 14.  Additional  Covenant.  Notwithstanding  any other provision of
this Agreement,  no adjustment to the Purchase  Price,  the number of shares (or


                                       35
<PAGE>

fractions of a share) of Preferred  Stock,  Common Stock or other securities for
which a Right is exercisable or the number of Rights  outstanding or any similar
adjustment  shall be made or be  effective  if such  adjustment  would  have the
effect of reducing or limiting the benefits the holders of the Rights would have
had absent such adjustment,  including,  without limitation,  the benefits under
Section 11(a)(ii) and Section 13, unless the terms of this Agreement are amended
so as to preserve such benefits.

     Section 15. Fractional Rights and Fractional Shares.

          (a) The Company  shall not be required to issue  fractions  of Rights,
     except prior to the  Distribution  Date as provided in Section 11(n), 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
     15(a), the current market value of a whole Right shall be the closing price
     of the Rights for the  Trading Day  immediately  prior to the date on which
     such  fractional  Rights would have been  otherwise  issuable.  The closing
     price of the Rights for any day shall be the last sale price,  regular way,
     or,  in case no such  sale  takes  place on such day,  the  average  of the
     closing bid and asked  prices,  regular  way, in either case as reported in
     the principal  consolidated  transaction  reporting  system with respect to
     securities listed or admitted to trading on the New York Stock Exchange or,
     if the Rights are not listed or  admitted  to trading on the New York Stock
     Exchange, as reported in the principal  consolidated  transaction reporting
     system  with  respect  to  securities  listed  on  the  principal  national
     securities  exchange on which the Rights are listed or admitted to trading,
     or if the  Rights  are not listed or  admitted  to trading on any  national
     securities  exchange,  the last  quoted  price  or, if not so  quoted,  the
     average  of the  high  bid and low  asked  prices  in the  over-the-counter
     market,  as reported  by NASDAQ or such other  system then in use or, if on


                                       36
<PAGE>

     any such  date the  Rights  are not  quoted by any such  organization,  the
     average of the closing bid and asked prices as furnished by a  professional
     market  maker  making a  market  in the  Rights  selected  by the  Board of
     Directors  of the  Company.  If on any such  date no such  market  maker is
     making a market in the  Rights the fair value of the Rights on such date as
     determined  reasonably  and with good faith to the holders of Rights by the
     Board of Directors of the Company shall be used and shall be binding on the
     Rights Agent.

          (b) The Company shall not be required to issue  fractions of shares of
     Preferred Stock (other than fractions  which are integral  multiples of one
     ten-thousandth  of a share of Preferred  Stock) upon exercise of the Rights
     or to distribute certificates which evidence fractional shares of Preferred
     Stock  (other  than   fractions   which  are  integral   multiples  of  one
     ten-thousandth of a share of Preferred Stock). In lieu of fractional shares
     of Preferred Stock that are not integral multiples of one ten-thousandth of
     a share of Preferred Stock,  the Company may pay to the registered  holders
     of Right  Certificates  at the time such  Rights  are  exercised  as herein
     provided an amount in cash equal to the same fraction of the current market
     value of one  ten-thousandth of a share of Preferred Stock. For purposes of
     this Section  15(b),  the current market value of one  ten-thousandth  of a
     share of Preferred Stock shall be one  ten-thousandth  of the closing price
     of a share  of  Preferred  Stock  (as  determined  pursuant  to of  Section
     11(d)(ii) hereof) for the Trading Day immediately prior to the date of such
     exercise.

          (c) Following  the  occurrence  of one of the  transactions  or events
     specified   in  Section  11  giving  rise  to  the  right  to  receive  one
     ten-thousandth  of a share  of  Preferred  Stock,  Common  Stock,  or other


                                       37
<PAGE>

     securities upon the exercise of a Right,  the Company shall not be required
     to issue fractions of shares of Common Stock upon exercise of the Rights or
     to  distribute  certificates  which  evidence  fractional  shares of Common
     Stock.  In lieu of  fractional  units of one  ten-thousandth  of a share of
     Preferred  Stock or  fractional  shares of any such other  securities,  the
     Company may pay to the registered holders of Right Certificates at the time
     such Rights are exercised as herein provided an amount in cash equal to the
     same  fraction  of the  current  market  value  of a unit or  share of such
     securities,  as the case may be. For  purposes of this Section  15(c),  the
     current  market value of any such unit or share shall be the closing  price
     of a share of Common  Stock (as  determined  pursuant to Section  11(d)(ii)
     hereof) for the Trading Day immediately prior to the date of such exercise.

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

     Section  16.  Rights of  Action.  All  rights of action in  respect of this
Agreement  (other than rights of action given to the Rights Agent under  Section
19  hereof)  are  vested in the  respective  registered  holders  of the  Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Stock and the Senior Preferred  Stock);  and any registered holder of any
Rights  Certificate (or, prior to the Distribution Date, of the Common Stock and
the Senior Preferred  Stock),  without the consent of the Rights Agent or of the
holder of any other Rights  Certificate (or, prior to the Distribution  Date, of
the Common Stock and the Senior Preferred Stock), may, in his own behalf and for
his own benefit,  enforce,  and may institute  and maintain any suit,  action or
proceeding  against the Company to enforce,  or otherwise act in respect of, his
right to exercise the Rights evidenced by such 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 shall be entitled to specific  performance
of the obligations  hereunder and injunctive relief against actual or threatened
violations of the obligations hereunder of any Person subject to this Agreement.


                                       38
<PAGE>

Holders  of  Rights  shall be  entitled  to  recover  the  reasonable  costs and
expenses,  including  attorneys' fees, incurred by them in any action to enforce
the provisions of this Agreement in which they successfully prosecute their
claims.

     Section  17.  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 Common Stock
and the Senior  Preferred  Stock;  (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 of the Rights  Agent,  duly  endorsed  or
accompanied  by a proper  instrument  of transfer;  (c) subject to Section 6 and
Section  7(f)  hereof,  the Company and the Rights  Agent may deem and treat the
person in whose name a Rights  Certificate (or, prior to the Distribution  Date,
the associated Common Stock or Senior Preferred Stock 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  Stock  or  Senior   Preferred  Stock
certificate  made by anyone other than the Company or the Rights  Agent) for all
purposes  whatsoever,  and neither the Company nor the Rights Agent,  subject to
the last sentence of Section 7(e) hereof, shall be affected by any notice to the
contrary; and

          (d)  notwithstanding  anything  in  this  Agreement  to the  contrary,
     neither the Company nor the Rights  Agent shall have any  liability  to any
     holder of a Right or a beneficial  interest in a Right or other Person as a
     result of its  inability  to  perform  any of its  obligations  under  this
     Agreement by reason of any  preliminary  or permanent  injunction  or other
     order, decree or ruling issued by a court of competent jurisdiction or by a


                                       39
<PAGE>

     governmental,  regulatory or  administrative  agency or commission,  or any
     statute,  rule, regulation or executive order promulgated or enacted by any
     governmental authority, prohibiting or otherwise restraining performance of
     such obligation;  provided,  however,  the Company shall not have sought or
     otherwise cooperated in obtaining such order, decree or ruling and must use
     its best  efforts  to have any such  order,  decree  or  ruling  lifted  or
     otherwise overturned as soon as possible.

     Section 18. 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 the holder of the shares of Preferred Stock, Common
Stock 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 thereof.

     Section 19.  Concerning the Rights Agent.  The Company agrees to pay to the
Rights Agent reasonable  compensation for all services  rendered by it hereunder
and, from time to time, on demand of the Rights Agent,  its reasonable  expenses
and  counsel  fees and  disbursements  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,  damage,  claim, 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


                                       40

in  connection  with  the  acceptance  and  administration  of  this  Agreement,
including  the costs and  expenses  (including  reasonable  attorney's  fees and
expenses)  of  defending  against  any  claim of  liability  arising  therefrom,
directly or  indirectly.  The  indemnity  provided  for in this Section 19 shall
survive the expiration of the Rights and the termination of this Agreement.

     The Rights Agent shall be protected  and shall incur no liability for or in
respect of any action taken,  suffered or omitted by it in  connection  with its
administration  of this  Agreement in reliance  upon any Rights  Certificate  or
certificate for Common Stock or for other securities of the Company,  instrument
of assignment or transfer, power of attorney,  endorsement,  affidavit,  letter,
notice, direction, consent,  certificate,  statement, or other paper or document
believed by it to be genuine and to be signed,  executed and,  where  necessary,
verified or acknowledged, by the proper Person or Persons.

     Section 20. Merger or  Consolidation or Change of Name of Rights Agent. Any
corporation  into which the Rights  Agent or any  successor  Rights Agent may be
merged or with which it may be consolidated,  or any corporation  resulting from
any merger or  consolidation  to which the Rights Agent or any successor  Rights
Agent shall be a party,  or any  corporation  succeeding to the 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 that such corporation  would be eligible for appointment as a successor
Rights Agent under the provisions of Section 22 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


                                       41
<PAGE>

countersigned,   any  successor   Rights  Agent  may  countersign   such  Rights
Certificates  either  in the  name  of the  predecessor  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 in this Agreement.

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

          (a) The Rights  Agent may consult  with legal  counsel  selected by it
     (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) 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 the  Chairman  of the


                                       42
<PAGE>

     Board, any Vice Chairman of the Board,  the President,  any Vice President,
     the  Treasurer,  any  Assistant  Treasurer,  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 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 as to the fact that it has  countersigned the
     Rights  Certificates)  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  thereof);  nor  shall it be  responsible  for any  Rights
     becoming null and void pursuant to Section 7(e) hereof or 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  adjustment
     required  under the  provisions of Sections 11 or 13 hereof or  responsible
     for the manner, method or amount of any such adjustment or the ascertaining
     of the  existence of facts that would require any such  adjustment  (except
     with  respect to the exercise of Rights  evidenced  by Rights  Certificates
     after actual notice of any such  adjustment);  nor shall it be  responsible
     for any  determination  by the Board of  Directors  of the  Company  of the
     current  market  value of the  Rights or  Preferred  Stock or Common  Stock
     pursuant to the  provisions  of Section 15 hereof;  nor shall it by any act


                                       43
<PAGE>

     hereunder  be  deemed  to make any  representation  or  warranty  as to the
     authorization  or  reservation  of any shares of Preferred  Stock or Common
     Stock to be issued pursuant to this Agreement or any Rights  Certificate or
     as to whether any shares of Preferred Stock (or fractional  shares thereof)
     or Common Stock will,  when so 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 and
     certificates  delivered  pursuant to any provision hereof from the Chairman
     of the Board,  any Vice  Chairman  of the Board,  the  President,  any Vice
     President,  the Secretary,  any Assistant  Secretary,  the Treasurer or any
     Assistant  Treasurer of the  Company,  and is  authorized  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 to be taken by it in
     good  faith  in  accordance  with  instructions  of any such  officer.  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 with  respect to its
     duties or  obligations  under this  Agreement  and the date on and/or after
     which such action taken or omitted in accordance  with a proposal  included
     in any such application on or after the date specified  therein (which date
     shall not be less than three  Business Days after the date any such officer
     actually  receives  such  application,  unless any such officer  shall have
     consented  in  writing  to an  earlier  date)  unless,  prior to  taking or
     omitting   any  such  action,   the  Rights  Agent  has  received   written
     instructions  from the Company in response to such  application  specifying
     the action to be taken or omitted.

                                       44
<PAGE>

          (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 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,  omission,  default,  neglect  or
     misconduct  of any such  attorneys or agents or for any loss to the Company
     or to the  holders of the  Rights  resulting  from any such act,  omission,
     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 of transfer  without first  consulting
     with the Company.

                                       45

     Section  22.  Change of Rights  Agent.  The Rights  Agent or any  successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer agent
of the Common Stock and Preferred  Stock by registered or certified  mail,  and,
subsequent to the  Distribution  Date, to holders of the Rights  Certificates by
first-class  mail.  The  Company  may remove the Rights  Agent or any  successor
Rights  Agent upon 30 days'  notice in  writing,  mailed to the Rights  Agent or
successor  Rights Agent,  as the case may be, and to each transfer  agent of the
Common  Stock  and  Preferred  Stock  by  registered  or  certified  mail,  and,
subsequent to the Distribution  Date, 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 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 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, in good standing,  which is authorized under such laws to exercise
corporate  trust 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 $50,000,000.  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  Right  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


                                       46
<PAGE>

execute and deliver any 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 Common Stock and Preferred  Stock,  and, if such
appointment occurs after the Distribution Date, mail a notice thereof in writing
to the registered holders of the Rights Certificates. Failure to give any notice
provided  for in this  Section 22,  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 23. 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 Purchase  Price per share 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 Stock  following the  Distribution  Date and
prior to the Expiration Date, the Company shall with respect to shares of Common
Stock 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
securities,  notes or debentures issued by the Company prior to the Distribution
Date, issue Right Certificates  representing the appropriate number of Rights in
connection with such issuance or sale; provided,  however,  that (i) the Company
shall not be obligated to issue any such Right Certificate if, and to the extent
that,  the Company shall be advised by counsel that such issuance would create a
significant  risk of  material  adverse tax  consequences  to the Company or the
Person  to whom  such  Right  Certificate  shall  be  issued,  and (ii) no Right
Certificate shall be issued if, and to the extent that,  appropriate  adjustment
shall otherwise have been made in lieu of the issuance thereof.

     Section 24. Redemption and Termination.

          (a) (i) The Board of Directors  of the Company may, at its option,  at
     any time prior to 5:00 P.M.,  Scottsdale,  Arizona  time, on the earlier of
     (x) the Stock Acquisition Date or (y) the Final Expiration Date, redeem all
     but not less  than all of the then  outstanding  Rights  at the  redemption
     price of $.0001  per Right,  appropriately  adjusted  to reflect  any stock
     split,  stock  dividend  or similar  transaction  occurring  after the date
     hereof  (such  redemption  price  being  hereinafter  referred  to  as  the
     "Redemption Price").

               (ii) In  addition,  a majority of the Board of  Directors  of the
          Company  may,  at  its  option,   at  any  time  following  the  Stock
          Acquisition  Date and the  expiration  of the period  during which the
          rights of holders of Rights pursuant to Section  11(a)(ii)  hereof may
          be exercised as a result of the  occurrence of such Stock  Acquisition
          Date,  but prior to any event  described in clause (x), (y), or (z) of
          Section  13(a)  hereof,  redeem  all but not less than all of the then
          outstanding Rights at the Redemption Price in connection with any such
          event in which all holders of shares of Common Stock are treated alike
          and not involving an Acquiring  Person or an Affiliate or Associate of
          an Acquiring  Person or any Person in which the Acquiring Person or an
          Affiliate or Associate of an Acquiring Person has an interest,  or any
          other Person acting  directly or indirectly on behalf of or in concert
          with any such  Acquiring  Person,  Associate or Affiliate  (other than
          involvement by an Acquiring Person, Affiliate, Associate or such other
          Person  solely as a holder of shares of Common  Stock (of the Company)
          being  treated  like all other  such  holders)  or (z)  following  the
          occurrence of an event set forth in, and the  expiration of any period
          during  which the holder of Rights  may  exercise  the  rights  under,
          Section  11(a)(ii) if and for as long as the  Acquiring  Person is not
          thereafter the Beneficial Owner of securities representing ten percent
          or more of the voting power of all securities of the Company generally
          entitled to vote for the election of directors of the Company.

                                       48
<PAGE>

          (b) Immediately  upon the date for redemption set forth (or determined
     in the manner  specified)  in a resolution 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.  Within  ten  days  after  the  action  of the  Board of
     Directors  ordering any such  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 the Rights Agent and 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 Stock. 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.

     Section 25. Notice of Certain Events. In case the Company at any time on or
after the  Distribution  Date shall  propose (a) to pay any dividend  payable in
stock of any  class  to the  holders  of  Preferred  Stock or to make any  other
distribution to the holders of Preferred  Stock (other than a regular  quarterly
cash  dividend  out of earnings or retained  earnings of the  Company) or (b) to
offer to the holders of Preferred  Stock rights or warrants to subscribe  for or
to purchase any additional  shares of Preferred  Stock or shares of stock of any
class  or any  other  securities,  rights  or  options,  or (c)  to  effect  any
reclassification of its Preferred Stock (other than a reclassification involving
only the subdivision of outstanding shares of Preferred Stock), or (d) to effect
any  consolidation  or  merger  into or  with,  or to  effect  any sale or other


                                       49
<PAGE>

transfer  (or to permit  one or more of its  subsidiaries  to effect any sale or
other transfer), in one or more transactions,  of more than 50% of the assets or
earning  power of the  Company and its  subsidiaries  (taken as a whole) to, any
other Person, or (e) to effect the liquidation, dissolution or winding up of the
Company,  then,  in each such case,  the Company  shall give to each holder of a
Rights  Certificate,  in  accordance  with  Section 26 hereof,  a notice of such
proposed  action,  which shall  specify the record date for the purposes of such
stock dividend,  distribution  of rights or warrants,  or the date on which such
reclassification,    consolidation,   merger,   sale,   transfer,   liquidation,
dissolution,  or  winding  up is to take  place  and the  date of  participation
therein by the holders of the shares of Preferred  Stock, if any such date is to
be fixed, and such notice shall be so given in the case of any action covered by
clause  (a) or (b)  above  at  least  20  days  prior  to the  record  date  for
determining  holders  of the  shares of  Preferred  Stock for  purposes  of such
action,  and in the case of any such other action, at least 20 days prior to the
date of the taking of such proposed action or the date of participation  therein
by the holders of the shares of Preferred Stock whichever shall be the earlier.

     In case any of the events set forth in Section  11(a)(ii) of this Agreement
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 Section
11(a)(ii) hereof.

     Section 26. Notices.  Notices or demands authorized by this Agreement to be

     Section 27. Supplements and Amendments. Prior to the Distribution Date, the
Company  may  from  time to time  supplement  or  amend  any  provision  of this
Agreement  in any respect  without the  approval of any holders of  certificates
representing  Common Stock and the Rights. From and after the Distribution Date,

ambiguity,  (ii) to correct or supplement any provision  contained  herein which
may be defective or  inconsistent  with any other  provisions  herein,  (iii) to
shorten or lengthen any time period  hereunder  or (iv) to change or  supplement
the  provisions  hereunder in any manner which the Company may deem necessary or
desirable and which shall not  adversely  affect the interests of the holders of

                                       51
<PAGE>

of an Acquiring  Person);  provided,  however,  that 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.  Upon the  delivery  of a
certificate  from an  appropriate  officer of the Company  which 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,  provided that
such supplement or amendment does not adversely affect the rights or obligations
of the Rights Agent under  Section 19 or Section 21 of this  Agreement  and such
amendment  or  supplement  shall be  effective  regardless  of  whether  or when
executed by the Rights Agent.  Prior to the Distribution  Date, the interests of
the  holders of Rights  shall be deemed  coincident  with the  interests  of the
holders of shares of Common Stock.

     Section 28. Determination and Actions by the Board of Directors,  etc.. 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,  without  limitation,  a  determination  to redeem or not
redeem the Rights or to amend the Agreement  and whether any proposed  amendment
adversely affects the interests of the holders of Right  Certificates).  For all
purposes of this  Agreement,  any  calculation of the number of shares of Common


                                       52
<PAGE>

Stock or other  securities  outstanding  at any particular  time,  including for
purposes of determining the particular  percentage of such outstanding shares of
Common  Stock or any  other  securities  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 as in effect on the
date of this  Agreement.  All such actions,  calculations,  interpretations  and
determinations  (including, for purposes of clause (y) below, all omissions with
respect  to the  foregoing)  which are done or made by the Board in good  faith,
shall (x) be final, conclusive and binding on the Company, the Rights Agent, the
holders of the Right Certificates and all other parties, and (y) not subject the
Board to any  liability to the holders of the Right  Certificates  or holders of
shares of Common Stock.

     Section 29. 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 30. Benefits of this Agreement.  Nothing in this Agreement shall be
construed  to give to any  person or  corporation  other than the  Company,  the
Rights Agent and the registered  holders of the Rights  Certificates (and, prior
to the Distribution Date, the Common Stock) any legal or equitable right, remedy
or claim  under this  Agreement;  but this  Agreement  shall be for the sole and
exclusive benefit of the Company, the Rights Agent and the registered holders of
the Rights Certificates (and, prior to the Distribution Date, the Common Stock).

     Section 31. Severability.  If any term, provision,  covenant or restriction
of this  Agreement  is  held  by a court  of  competent  jurisdiction  or  other
authority  to be invalid,  void or  unenforceable,  the  remainder of the terms,
provisions,  covenants and  restrictions  of this Agreement shall remain in full
force and effect and shall in no way be affected, impaired or invalidated.

     Section  32.  Governing  Law.  This  Agreement,  each Right and each Rights
Certificate  issued  hereunder  shall be deemed to be a contract  made under the


                                       53

laws of the State of  Delaware  and for all  purposes  shall be  governed by and
construed in accordance  with the laws of such State  applicable to contracts to
be made and to be performed entirely within such State.

               CERTIFICATE OF DESIGNATION, PREFERENCES AND RIGHTS
                OF SERIES B JUNIOR PARTICIPATING PREFERRED STOCK

                                       of

                          ALLIED WASTE INDUSTRIES, INC.

             Pursuant to Section 151 of the General Corporation Law
                            of the State of Delaware

     We,  Thomas H. Van  Weelden,  Chairman  of the Board,  President  and Chief
Executive Officer,  and Steven M. Helm, Vice  President-Legal and Secretary,  of
Allied Waste  Industries,  Inc., a corporation  organized and existing under the
General  Corporation  Law of the  State  of  Delaware,  in  accordance  with the
provisions of Section 103 thereof, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by the
Amended and Restated  Certificate of  Incorporation  of the said Corporation and
Section 151(g) of the General Corporation Law of the State of Delaware, the said
Board of Directors on May 18, 2000 adopted the following resolution at a meeting
duly called and held:.

     RESOLVED,  that pursuant to the authority  vested in the Board of Directors
of this  Corporation  in  accordance  with the  provisions  of its  Amended  and
Restated  Certificate  of  Incorporation  and  Section  151(g)  of  the  General
Corporation Law of the State of Delaware,  the Board of Directors hereby creates
a series of Preferred Stock of the Corporation and hereby states the designation
and  number of  shares,  and fixes the  relative  rights,  preferences,  powers,
qualifications and limitations thereof as follows:

     Section 1.  Designation  and  Amount.  The shares of such  series  shall be
designated as "Series B Junior  Participating  Preferred  Stock," par value $.10
per share, and the number of shares  constituting  such series shall be 500,000.
Such number of shares may be increased or decreased by  resolution  of the Board
of Directors;  provided,  that no decrease  shall reduce the number of shares of
Series B Junior  Preferred  Stock to a number  less than that of the shares then
outstanding  plus the number of shares  issuable  upon  exercise of  outstanding
rights,  options or warrants or upon conversion of outstanding securities issued
by the Corporation.

     Section 2. Dividends and Distributions.


     (A) Subject to the prior and  superior  rights of the holders of any shares
of any series of  Preferred  Stock  ranking  prior and superior to the shares of


                                       56
<PAGE>

Series B Junior  Participating  Preferred  Stock with respect to dividends,  the
holders  of  shares  of  Series  B  Junior  Participating  Preferred  Stock,  in
preference to the holders of shares of Common  Stock,  par value $0.01 per share
(the "Common  Stock"),  of the Corporation and any other junior stock,  shall be
entitled to receive,  when,  as and if declared by the Board of Directors out of
funds legally available for the purpose,  quarterly dividends payable in cash on
the last day of each of March, June, September and December in each year (or, in
each case, if not a date on which the Corporation is open for business, the next
succeeding  business  day) or such  earlier  date in any  such  month  on  which
dividends  on the Common  Stock are  payable  (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 B Junior  Participating  Preferred  Stock, in an amount per
share  (rounded to the  nearest  cent) equal to the greater of (a) $10.00 or (b)
subject to the provision for adjustment  hereinafter set forth, 10,000 times the
aggregate per share amount of all cash dividends, and 10,000 times the aggregate
per  share  amount  (payable  in  kind)  of  all  non-cash  dividends  or  other
distributions  other  than a  dividend  payable  in shares of Common  Stock or a
subdivision of the outstanding  shares of Common Stock (by  reclassification  or
otherwise),  declared  on the  Common  Stock,  since the  immediately  preceding
Quarterly  Dividend  Payment  Date,  or,  with  respect  to the first  Quarterly
Dividend  Payment Date,  since the first  issuance of any share or fraction of a
share  of  Series B Junior  Participating  Preferred  Stock.  In the  event  the
Corporation shall at any time after May 31, 2000 (the "Rights Declaration Date")
(i) declare any dividend on 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  amount to
which holders of shares of Series B Junior  Participating  Preferred  Stock were
entitled  immediately  prior to such event  under  clause  (b) of the  preceding
sentence  shall be  adjusted  by  multiplying  such  amount  by a  fraction  the
numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

     (B) The Corporation  shall declare a dividend or distribution on the Series
B Junior  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); provided that, in the
event no dividend or  distribution  shall have been declared on the Common Stock
during the period  between  any  Quarterly  Dividend  Payment  Date and the next
subsequent  Quarterly  Dividend  Payment Date, a dividend of $10.00 per share on
the Series B Junior Participating  Preferred Stock shall nevertheless be payable
on such subsequent Quarterly Dividend Payment Date.

     (C) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series B Junior  Participating  Preferred  Stock from the Quarterly  Dividend


                                       57
<PAGE>

Payment Date next  preceding the date of issue of such shares of Series B Junior
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
B Junior 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 and be cumulative  from such Quarterly  Dividend
Payment Date.  Accrued but unpaid  dividends shall not bear interest.  Dividends
paid on the shares of Series B Junior 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 B  Junior  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.

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

     (A) Subject to the provision for  adjustment  hereinafter  set forth,  each
share of Series B Junior Participating  Preferred Stock shall entitle the holder
thereof to 10,000 votes on all matters  submitted to a vote of the  stockholders
of the  Corporation.  In the event the  Corporation  shall at any time after the
Rights  Declaration  Date (i) declare any  dividend on 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  number  of votes  per  share to which  holders  of shares of
Series B Junior Participating Preferred Stock were entitled immediately prior to
such event  shall be  adjusted  by  multiplying  such  number by a fraction  the
numerator  of  which  is the  number  of  shares  of  Common  Stock  outstanding
immediately  after  such  event and the  denominator  of which is the  number of
shares of Common Stock that were outstanding immediately prior to such event.

     (B) Except as otherwise provided herein or by law, the holders of shares of
Series B Junior  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) (i) If at any time  dividends  on any  Series  B  Junior  Participating
Preferred  Stock  shall be in  arrears in an amount  equal to six (6)  quarterly
dividends  thereon,  the occurrence of such contingency shall mark the beginning
of a period  (herein  called a "default  period")  which shall extend until such


                                       58
<PAGE>

time when all accrued and unpaid dividends for all previous  quarterly  dividend
periods and for the current quarterly  dividend period on all shares of Series B
Junior  Participating  Preferred Stock then outstanding shall have been declared
and paid or set apart for payment.  During each default  period,  all holders of
Preferred  Stock  (including  holders  of  the  Series  B  Junior  Participating
Preferred  Stock)  with  dividends  in  arrears  in an  amount  equal to six (6)
quarterly dividends thereon,  voting as a class,  irrespective of series,  shall
have the right to elect two (2) Directors.

          (ii) During any default  period,  such voting  right of the holders of
     Series B Junior Participating Preferred Stock may be exercised initially at
     a special  meeting called  pursuant to  subparagraph  (iii) of this Section
     3(C) or at any annual  meeting of  stockholders,  and  thereafter at annual
     meetings of  stockholders,  provided that neither such voting right nor the
     right of the holders of any other  series of  Preferred  Stock,  if any, to
     increase,  in certain cases,  the authorized  number of Directors  shall be
     exercised  unless the holders of ten  percent  (10%) in number of shares of
     Preferred  Stock  outstanding  shall be present in person or by proxy.  The
     absence  of a quorum of the  holders of Common  Stock  shall not affect the
     exercise by the holders of  Preferred  Stock of such voting  right.  At any
     meeting at which the holders of Preferred  Stock shall exercise such voting
     right  initially  during an existing  default  period,  they shall have the
     right,  voting as a class, to elect  Directors to fill such  vacancies,  if
     any, in the Board of  Directors  as may then exist up to two (2)  Directors
     or,  if such  right is  exercised  at an annual  meeting,  to elect two (2)
     Directors.  If the number  which may be so elected at any  special  meeting
     does not amount to the required number,  the holders of the Preferred Stock
     shall have the right to make such  increase in the number of  Directors  as
     shall be necessary  to permit the election by them of the required  number.
     After the holders of the Preferred  Stock shall have exercised  their right
     to elect Directors in any default period and during the continuance of such
     period,  the number of Directors shall not be increased or decreased except
     by vote of the holders of Preferred Stock as herein provided or pursuant to
     the rights of any equity  securities  ranking  senior to or pari passu with
     the Series B Junior Participating Preferred Stock.

          (iii) Unless the holders of Preferred Stock shall,  during an existing
     default period,  have previously  exercised their right to elect Directors,
     the Board of Directors may order, or any stockholder or stockholders owning
     in the  aggregate  not less than ten percent  (10%) of the total  number of
     shares of Preferred Stock outstanding, irrespective of series, may request,
     the calling of special  meeting of the holders of  Preferred  Stock,  which
     meeting shall thereupon be called by the President, a Vice-President or the
     Secretary  of the  Corporation.  Notice of such  meeting  and of any annual
     meeting at which  holders of Preferred  Stock are entitled to vote pursuant
     to this  paragraph  (C)(iii)  shall be given to each  holder  of  record of
     Preferred Stock by mailing a copy of such notice to him at his last address
     as the same appears on the books of the Corporation.  Such meeting shall be


                                       59
<PAGE>

     called for a time not earlier than 20 days and not later than 60 days after
     such order or request or in default of the calling of such  meeting  within
     60 days after such order or request,  such meeting may be called on similar
     notice by any stockholder or stockholders  owning in the aggregate not less
     than ten percent  (10%) of the total  number of shares of  Preferred  Stock
     outstanding.  Notwithstanding the provisions of this paragraph (C)(iii), no
     such  special  meeting  shall be called  during the  period  within 60 days
     immediately  preceding  the date fixed for the next  annual  meeting of the
     stockholders.

          (iv) In any default  period,  the holders of Common  Stock,  and other
     classes of stock of the  Corporation  if  applicable,  shall continue to be
     entitled  to elect  the whole  number of  Directors  until the  holders  of
     Preferred Stock shall have exercised their right to elect two (2) Directors
     voting as a class,  after the exercise of which right (x) the  Directors so
     elected by the holders of  Preferred  Stock shall  continue in office until
     their  successors  shall  have been  elected  by such  holders or until the
     expiration  of the  default  period,  and (y) any  vacancy  in the Board of
     Directors  may (except as provided in paragraph  (C)(ii) of this Section 3)
     be filled by vote of a  majority  of the  remaining  Directors  theretofore
     elected by the  holders of the class of stock which  elected  the  Director
     whose office shall have become vacant.  References in this paragraph (C) to
     Directors  elected by the  holders  of a  particular  class of stock  shall
     include  Directors  elected by such Directors to fill vacancies as provided
     in clause (y) of the foregoing sentence.

          (v) Immediately upon the expiration of a default period, (x) the right
     of the  holders  of  Preferred  Stock as a class to elect  Directors  shall
     cease,  (y) the term of any  Directors  elected by the holders of Preferred
     Stock as a class shall terminate,  and (z) the number of Directors shall be
     such number as may be provided for in the Certificate of  Incorporation  or
     By-laws  irrespective  of any increase made  pursuant to the  provisions of
     paragraph (C)(ii) of this Section 3 (such number being subject,  however to
     change  thereafter in any manner  provided by law or in the  Certificate of
     Incorporation or By-laws). Any vacancies in the Board of Directors effected
     by the  provisions of clauses (y) and (z) in the preceding  sentence may be
     filled by a majority of the remaining Directors.

     (D) Except as set forth  herein,  holders of Series B Junior  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 4.  Certain Restrictions.


                  (A)  Whenever  quarterly   dividends  or  other  dividends  or
distributions  payable on the Series B Junior  Participating  Preferred Stock as


                                       60
<PAGE>

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
B Junior 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 B Junior  Participating  Preferred
     Stock;

          (ii) declare or pay  dividends on or make any other  distributions  on
     any shares of stock  ranking on a parity  (either as to  dividends  or upon
     liquidation,   dissolution   or  winding  up)  with  the  Series  B  Junior
     Participating  Preferred Stock, except dividends paid ratably on the Series
     B Junior  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  B  Junior
     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  Corporation  ranking  junior
     (either as to dividends or upon dissolution,  liquidation or winding up) to
     the Series B Junior Participating Preferred Stock;

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

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

                                       61
<PAGE>

     Section 5. Reacquired Shares.  Any shares of Series B Junior  Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever  shall be  retired  and  cancelled  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.

     Section 6. Liquidation, Dissolution or Winding Up. (A) Upon any liquidation
(voluntary  or  otherwise),  dissolution  or winding up of the  Corporation,  no
distribution  shall be made to the  holders  of shares of stock  ranking  junior
(either as to dividends or upon  liquidation,  dissolution or winding up) to the
Series B Junior Participating Preferred Stock unless, prior thereto, the holders
of shares of Series B Junior  Participating  Preferred Stock shall have received
$10,000  per share,  plus an amount  equal to accrued and unpaid  dividends  and
distributions thereon, whether or not declared, to the date of such payment (the
"Series B Liquidation Preference").  Following the payment of the full amount of
the Series B Liquidation Preference,  no additional  distributions shall be made
to the  holders  of  shares  of Series B Junior  Participating  Preferred  Stock
unless, prior thereto, the holders of shares of Common Stock shall have received
an amount per share (the "Common  Adjustment") equal to the quotient obtained by
dividing  (i)  the  Series  B   Liquidation   Preference   by  (ii)  10,000  (as
appropriately  adjusted  as set forth in  subparagraph  C below to reflect  such
events as stock splits,  stock dividends and  recapitalizations  with respect to
the  Common  Stock)  (such  number in clause  (ii),  the  "Adjustment  Number").
Following the payment of the full amount of the Series B Liquidation  Preference
and the  Common  Adjustment  in respect  of all  outstanding  shares of Series B
Junior Participating Preferred Stock and Common Stock, respectively,  holders of
Series B Junior  Participating  Preferred  Stock and holders of shares of Common
Stock shall  receive  their  ratable and  proportionate  share of the  remaining
assets to be distributed in the ratio of the Adjustment Number to 1 with respect
to such Preferred Stock and Common Stock, on a per share basis, respectively.

     (B) In the  event  there  are not  sufficient  assets  available  to permit
payment  in full of the  Series B  Liquidation  Preference  and the  liquidation
preferences  of all other series of  preferred  stock,  if any,  which rank on a
parity  with the  Series B  Junior  Participating  Preferred  Stock,  then  such
remaining  assets  shall be  distributed  ratably to the  holders of such parity
shares in proportion to their respective liquidation  preferences.  In the event
there are not  sufficient  assets  available  to permit  payment  in full of the
Common  Adjustment,  then such remaining assets shall be distributed  ratably to
the holders of Common Stock.

     (C) In the  event  the  Corporation  shall at any  time  after  the  Rights
Declaration  Date (i) declare any dividend on 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  Adjustment  Number  in  effect  immediately  prior to such  event  shall be
adjusted by multiplying  such  Adjustment  Number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

     Section 7. Consolidation,  Merger, etc. In case the Corporation shall enter
into any  consolidation,  merger,  combination or other transaction in which the
shares  of  Common  Stock are  exchanged  for or  changed  into  other  stock or
securities,  cash and/or any other property, then in any such case the shares of
Series  B  Junior  Participating  Preferred  Stock  shall  at the  same  time be
similarly  exchanged or changed in an amount per share (subject to the provision
for adjustment hereinafter set forth) equal to 10,000 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.  In the  event the  Corporation  shall at any time  after the  Rights
Declaration  Date (i) declare any dividend on 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 amount set forth in the  preceding  sentence with respect to the exchange or
change  of  shares of Series B Junior  Participating  Preferred  Stock  shall be
adjusted by multiplying  such amount by a fraction the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of  Common  Stock  that are
outstanding immediately prior to such event.

     Section  8. No  Redemption.  The  shares of  Series B Junior  Participating
Preferred Stock shall not be redeemable.

     Section 9. Ranking. The Series B Junior 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  10.   Amendment.   The  Amended  and   Restated   Certificate   of
Incorporation  of the  Corporation  shall not be  further  amended in any manner
which would materially alter or change the powers, preferences or special rights
of the  Series B Junior  Participating  Preferred  Stock  so as to  affect  them
adversely  without the affirmative  vote of the holders of a majority or more of
the outstanding shares of Series B Junior Participating  Preferred Stock, voting
separately as a class.

     Section 11.  Fractional  Shares.  Series B Junior  Participating  Preferred
Stock may be issued in fractions of a share which shall  entitle the holder,  in
proportion to such holders fractional shares, to exercise voting rights, receive
dividends,  participate  in  distributions  and to have the benefit of all other
rights of holders of Series B Junior Participating Preferred Stock.

                                                               Exhibit C

                          SUMMARY OF RIGHTS TO PURCHASE
                                 PREFERRED STOCK

     On May 18, 2000,  the Board of Directors of Allied Waste  Industries,  Inc.
(the  "Company")  declared  a  dividend  distribution  of  one  Right  for  each
outstanding  share of common  stock,  par value  $0.01  per share  (the  "Common
Stock"),  of the Company to  stockholders  of record at the close of business on
May  31,  2000  (the  "Record  Date")  and  a  dividend  distribution  for  each
outstanding share of Series A Senior Convertible Preferred Stock, par value $.10
per share, of the Company (the "Senior Preferred Stock"), equal to the number of
Rights  which would have been  received by the holder if he had  converted  such
share  into  Common  Stock  immediately  prior to the  Record  Date,  payable to
stockholders  of record as of the Record Date.  Except as set forth below,  each
Right,  when  exercisable,  entitles the registered  holder to purchase from the
Company one ten-thousandth of a share of a series of preferred stock, designated
as Series B Junior Participating  Preferred Stock, par value $.10 per share (the
"Preferred  Stock"),  at a price of $85 per one ten  thousandth  of a share (the
"Purchase Price), subject to adjustment. The description and terms of the Rights
are set forth in a Rights Agreement (the "Rights Agreement") between
the Company and American Stock Transfer & Trust Company, as Rights Agent.

     Until the earlier to occur of (i) a public  announcement  that, without the
prior  consent of the Board of Directors  of the  Company,  a person or group of
affiliated  or  associated  persons (an  "Acquiring  Person") has  acquired,  or
obtained  the right to  acquire,  beneficial  ownership  of stock of the Company
representing  15% or more of the voting  power of all  outstanding  stock of the
Company  generally  entitled  to vote for the  election  of  directors  ("Voting
Stock") (the "Stock Acquisition Date"), or (ii) ten business days (or such later
date as the Board may  determine)  following  the  commencement  of (or a public
announcement  of an intention  to make) a tender  offer or exchange  offer which
would  result in any  person  or group and  related  persons  having  beneficial
ownership of 15% or more of the voting power of all outstanding shares of Voting
Stock  without the prior  consent of the Board of  Directors of the Company (the
earlier of such dates being called the "Distribution  Date"), the Rights will be
evidenced,  with  respect to any of the Common Stock or Senior  Preferred  Stock
certificates  outstanding  as of May 31,  2000,  by such Common  Stock or Senior
Preferred  Stock  certificate  and  no  separate  Rights  Certificates  will  be
distributed.  The Rights Agreement  provides that, until the Distribution  Date,
the  Rights  will be  transferred  with and only  with  Common  Stock or  Senior
Preferred Stock certificates. Until the Distribution Date (or earlier redemption
or  expiration  of the  Rights),  new  Common  Stock or Senior  Preferred  Stock
certificates  issued after May 31, 2000, (or as soon  thereafter as practicable)


                                       75
<PAGE>

upon transfer or new issuance of the Common Stock or Senior Preferred Stock will
contain a notation  incorporating  the Rights Agreement by reference.  Until the
Distribution  Date (or earlier  redemption  or  expiration  of the Rights),  the
surrender for transfer of any  certificates for Common Stock or Senior Preferred
Stock  outstanding as of May 31, 2000,  will also constitute the transfer of the
Rights associated with the Common Stock or Senior Preferred Stock represented by
such certificate,  even without such notation.  As soon as practicable following
the  Distribution  Date,  separate  certificates  evidencing the Rights ("Rights
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date, and the separate Rights Certificates
alone will evidence the Rights.

     Notwithstanding  the foregoing,  the stock  ownership of the holders of the
Senior Preferred  Stock,  their affiliates and certain related parties shall not
result in their  becoming an  Acquiring  Person if their stock  ownership  is in
compliance with the terms of their Shareholders Agreement with the Company.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on May 31,  2010,  unless  earlier  redeemed by the Company as  described
below.

     In the event that any person becomes an Acquiring Person,  each holder of a
Right  generally  will  thereafter  have the right for a 60 day period after the
later  of the  date  of  such  event  or  the  effectiveness  of an  appropriate
registration  statement  (or  such  other  longer  period  set by the  Board  of
Directors)  to receive  upon  exercise  of the Right that number of units of one
ten-thousandths of a share of Preferred Stock (or, under certain  circumstances,
Common  Stock or other  securities)  having an  average  market  value  during a
specified time period  (immediately prior to the occurrence of a Person becoming
an Acquiring  Person) of two times the  exercise  price of the Right (such right
being called the "Subscription Right"). Notwithstanding the foregoing, following
the occurrence of a Person becoming an Acquiring Person, all Rights that are, or
(under  certain   circumstances   specified  in  the  Rights   Agreement)  were,
beneficially owned by the Acquiring Person or any affiliate or associate thereof
will be null and void.

     In the event that, at any time  following the Stock  Acquisition  Date, the
Company is acquired in a merger or other business combination transaction or 50%
or more of the Company's assets or earning power are sold (in one transaction or
a series of transactions), proper provision shall be made so that each holder of
a Right  (except a Right voided as set forth above)  shall  thereafter  have the
right to receive,  upon the exercise  thereof at the then current exercise price
of the Right,  that number of shares of common  stock of the  acquiring  company
(or,  in the  event  there is more than one  acquiring  company,  the  acquiring
company   receiving  the  greatest  portion  of  the  assets  or  earning  power
transferred)  which at the time of such transaction would have a market value of
two times the  exercise  price of the Right (such right being called the "Merger
Right"). The holder of a Right will continue to have the Merger Right whether or
not such holder exercises the Subscription Right.

     The Purchase Price payable, the number of Rights and the number of units of
one  ten-thousandths of a share of Preferred Stock or shares of the Common Stock
or other  securities  or  property  issuable,  upon  exercise  of the Rights are
subject to adjustment from time to time to prevent  dilution (i) in the event of
a stock dividend on, or a subdivision,  combination or  reclassification  of the
Preferred  Stock,  (ii)  upon the grant to  holders  of the  Preferred  Stock of
certain rights or warrants to subscribe for Preferred Stock, certain convertible
securities or securities  having the same or more favorable  rights,  privileges
and  preferences as the Preferred Stock at less than the current market price of
the Preferred  Stock or (iii) upon the  distribution to holders of the Preferred
Stock of evidences of indebtedness or assets  (excluding  regular quarterly cash
dividends  out of  earnings  or  retained  earnings  and  dividends  payable  in
Preferred  Stock)  or of  subscription  rights or  warrants  (other  than  those
referred to above).

     With certain  exceptions,  no  adjustments  in the  Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such Purchase Price. No fractions of shares will be issued and, in lieu thereof,
an adjustment in cash will be made based on the market price of the Common Stock
on the last trading date prior to the date of exercise.

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

     At any time prior to the  earlier to occur of (i) the close of  business on
the Stock Acquisition Date or (ii) the expiration of the Rights, the Company may
redeem the Rights in whole, but not in part, at a price of $.0001 per Right (the
"Redemption Price"),  which redemption shall be effective upon the action of the
Board of Directors.  Additionally,  following the Stock Acquisition Date and the
expiration of the period during which the Subscription Right is exercisable, the
Board of Directors may redeem the then  outstanding  Rights in whole, but not in
part, at the  Redemption  Price  provided that such  redemption is in connection
with  a  merger  or  other  business   combination   transaction  or  series  of
transactions  involving  the  Company in which all  holders of Common  Stock are
treated  alike but not  involving an Acquiring  Person (or any person who was an
Acquiring Person) or it affiliates or associates. Upon the effective date of the
redemption  of the Rights,  the right to exercise the Rights will  terminate and
the only right of the holders of Rights will be to receive the Redemption Price.

     The  Preferred  Stock  purchasable  upon  exercise  of the  Rights  will be
nonredeemable  and junior to any other series of preferred stock the Company may
issue  (unless  otherwise  provided in the terms of such  stock).  Each share of
Preferred Stock will have a preferential  quarterly  dividend in an amount equal
to the greater of $10.00 and 10,000 times the  dividend  declared on each Common
Share. In the event of liquidation,  the holders of Preferred Stock will receive
a preferred liquidation payment equal to the greater of $10,000 and 10,000 times
the  payment  made per Common  Share.  Each share of  Preferred  Stock will have
10,000  votes,  voting  together  with the  Common  Shares.  In the event of any
merger, consolidation or other transaction in which Common Shares are exchanged,
each share of  Preferred  Stock will be  entitled  to receive  10,000  times the
amount and type of  consideration  received per Common Share.  The rights of the
Preferred  Stock as to dividends,  liquidation  and voting,  and in the event of
mergers and consolidations, are protected by customary anti-dilution provisions.
Fractional shares of Preferred Stock in integral multiples of one ten-thousandth
of a share of Preferred Stock will be issuable;  however,  the Company may elect
to distribute  depositary receipts in lieu of such fractional shares. In lieu of
fractional shares other than fractions that are multiples of one  ten-thousandth
of a share,  an adjustment in cash will be made based on the market price of the
Preferred Stock on the last trading date prior to the date of exercise.

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

     Except as set forth  above,  the terms of the  Rights may be amended by the
Board of  Directors of the Company,  (i) prior to the  Distribution  Date in any
manner,  and (ii) on or after the  Distribution  Date to cure any ambiguity,  to
correct  or  supplement  any  provision  of the  Rights  Agreement  which may be
defective  or  inconsistent  with any other  provisions,  or in any  manner  not
adversely affecting the interests of the holders of the Rights.

     A copy of the  Rights  Agreement  has been filed  with the  Securities  and
Exchange  Commission  as an Exhibit to a  Registration  Statement on Form 8-A. A
copy of the Rights Agreement is available free of charge from the Company.  This
summary  description  of the  Rights  does not  purport  to be  complete  and is
qualified  in its  entirety  by  reference  to the  Rights  Agreement,  which is
incorporated herein by reference.
