================================================================================

Item 1.  Description of Registrant's Securities to be Registered.

         On May 7, 1998,  the Board of Directors of TII  Industries,  Inc.  (the
"Company") declared a dividend of one preferred share purchase right (a "Right")
for each  outstanding  share of  common  stock,  par value  $.01 per share  (the
"Common Shares"),  of the Company.  The dividend is payable on May 21, 1998 (the
"Record Date") to the  stockholders of record at the opening of business on that
date. Each Right entitles the registered holder to purchase from the Company one
one-thousandth of a share of Series D Junior Participating  Preferred Stock, par
value  $1.00 per share (each whole  share  being a  "Preferred  Share"),  of the
Company at a price of $30.00 per each one  one-thousandth  of a Preferred  Share
(the "Purchase Price"), subject to adjustment.  The description and terms of the
Rights are set forth in a Rights Agreement (the "Rights  Agreement") between the
Company and Harris Trust & Savings Bank, as Rights Agent (the "Rights Agent").

         Until  the  earlier  to  occur  of  (i)  10  days  following  a  public
announcement  that a person or group of  affiliated  or  associated  persons (an
"Acquiring  Person")  have acquired  beneficial  ownership of 20% or more of the
outstanding Common Shares or (ii) 10 business days (or such later date as may be
determined  by the  Board  of  Directors)  following  the  commencement  of,  or
announcement  of an  intention  to make,  a tender  offer or exchange  offer the
consummation  of which would result in the  beneficial  ownership by a person or
group of 20% or more of the outstanding Common Shares (the earlier of such dates
being the "Distribution  Date"),  the Rights will be evidenced,  with respect to
any of the Common Share certificates  outstanding as of the Record Date, by such
Common Share certificate with a copy of the Summary of Rights attached thereto.

         The Rights Agreement  provides that,  until the Distribution  Date, the
Rights  will be  transferred  with and only with the  Common  Shares.  Until the
Distribution  Date (or earlier  redemption  or  expiration  of the Rights),  new
Common  Share  certificates  issued  after the Record Date upon  transfer or new
issuance  of Common  Shares  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 Shares outstanding as of the Record Date, even without such notation or a
copy of the Summary of Rights being attached  thereto,  will also constitute the
transfer of the Rights  associated  with the Common Shares  represented  by such
certificate.  As soon as practicable  following the Distribution Date,  separate
certificates  evidencing  the Rights  ("Right  Certificates")  will be mailed to
holders  of record of the  Common  Shares  as of the  close of  business  on the
Distribution Date and such separate Right  Certificates  alone will evidence the
Rights.

         The Rights are not exercisable until the Distribution  Date. The Rights
will  expire on May 15,  2008 (the "Final  Expiration  Date"),  unless the Final
Expiration  Date is  extended  or unless  the  Rights are  earlier  redeemed  or
exchanged by the Company, in each case, as described below.

         The Purchase Price payable, and the number of Preferred Shares 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
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Shares at a price,  or
securities  convertible into Preferred Shares with a conversion price, less than
the then-current market price


                                       - 2 -


<PAGE>

of the  Preferred  Shares  or (iii)  upon the  distribution  to  holders  of the
Preferred  Shares of  evidences of  indebtedness  or assets  (excluding  regular
periodic cash dividends  paid out of earnings or retained  earnings or dividends
payable in Preferred  Shares) or of subscription  rights or warrants (other than
those referred to above).

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

         Preferred  Shares  purchasable  upon exercise of the Rights will not be
redeemable.  Each Preferred  Share,  when issued,  will be entitled to a minimum
preferential quarterly dividend payment of $10 per share but will be entitled to
an aggregate  dividend of 1000 times the dividend  declared per Common Share. In
the event of liquidation,  the holders of the Preferred  Shares will be entitled
to a minimum  preferential  liquidation  payment  of $1000 per share but will be
entitled  to an  aggregate  payment  of 1000 times the  payment  made per Common
Share.  Each  Preferred  Share will have 1000 votes,  voting  together  with the
Common  Shares.  Finally,  in the event of any  merger,  consolidation  or other
transaction in which Common Shares are exchanged,  each Preferred  Share will be
entitled  to receive  1000 times the amount  received  per Common  Share.  These
rights are protected by customary anti-dilution provisions.

         Because of the nature of the Preferred  Shares'  dividend,  liquidation
and voting rights, the value of the one  one-thousandth  interest in a Preferred
Share  purchasable  upon exercise of each Right should  approximate the value of
one Common Share.

         In the event  that,  after a person or group  has  become an  Acquiring
Person,  the  Company  is  acquired  by any  other  person  in a merger or other
business  combination  transaction or 50% or more of its consolidated  assets or
earning power are sold,  proper  provision will be made so that each holder of a
Right will  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 entity acquiring the Company or its assets having a market value of
two times the exercise price of the Right.

         In the event  that any  person  or group of  affiliated  or  associated
persons becomes an Acquiring Person, proper provision shall be made so that each
holder of a Right, other than Rights  beneficially owned by the Acquiring Person
(which will thereafter be void),  will thereafter have the right to receive upon
exercise  that number of Shares  having a market value of two times the exercise
price of the Right. If the number of Common Shares available for issuance is not
sufficient to permit the exercise in full of the Rights,  the Company will issue
securities,  cash,  debt or other assets having an economic value  equivalent to
the economic value of the Rights or will reduce the purchase price.

         At any time after any person or group  becomes an Acquiring  Person and
prior  to the  acquisition  by such  person  or  group  owns  50% or more of the
outstanding  Common  Shares,  the Board of Directors of the Company may exchange
the Rights  (other  than  Rights  owned by such  person or group which will have
become void),  in whole or in part, at an exchange ratio of one Common Share, or
one one-thousandth of a Preferred Share (or of a share of a class or series of


                                       - 3 -

<PAGE>


the  Company's  preferred  stock  having  equivalent  rights,   preferences  and
privileges), per Right (subject to adjustment).

         With certain  exceptions,  no adjustment in the Purchase  Price will be
required until  cumulative  adjustments  require an adjustment of at least 1% in
such Purchase Price. No fractional  Preferred  Shares will be issued (other than
fractions  which are  integral  multiples of one  one-thousandth  of a Preferred
Share,  which may, at the  election of the Company,  be evidenced by  depositary
receipts) and, in lieu thereof,  an adjustment in cash will be made based on the
market price of the  Preferred  Shares on the last trading day prior to the date
of exercise.

         At any time  prior  to the time  after a  person  or group  becomes  an
Acquiring  Person,  the Board of Directors of the Company may redeem the Rights,
in whole but not in part, at a price of $.01 per Right (the "Redemption Price").
The Board may  redeem the  Rights  within  ten days after any person  becomes an
Acquiring  Person if such person  notifies the Board that the stock  acquisition
was  inadvertent  and during the ten day period,  and at the time of redemption,
such  person no longer owns 20% or more of the  outstanding  Common  Stock.  The
redemption  of the Rights may be made  effective at such time on such basis with
such  conditions  as the  Board  of  Directors,  in  its  sole  discretion,  may
establish.  Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price.

         Until the Rights become  exercisable the terms of the Rights  Agreement
may be  amended or  supplemented  without  the  approval  of any  holders of the
Rights.  Following  the  Distribution  Date,  the  Company  can amend the Rights
Agreement only to cure an ambiguity, to correct or supplement a provision of the
Rights Agreement which may be defective or inconsistent with other provisions of
the Rights  Agreement,  to shorten or lengthen the time periods set forth in the
Rights  Agreement,  or to change or  supplement  the  provisions  of the  Rights
Agreement  in a manner not adverse to the  holders of the Rights  (other than an
Acquiring  Person).  During  any  time  that  the  Rights  are  not  subject  to
redemption,  the Company may not amend the Rights Agreement to lengthen any time
period  relating to when the Rights may be  redeemed or lengthen  any other time
period unless such  lengthening  is for the purpose of protecting the holders of
the Rights.

         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.

         A copy of the Rights  Agreement  has been  filed as an Exhibit  hereto.
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 hereby
incorporated herein by reference.

                                RIGHTS AGREEMENT


         Rights  Agreement,  dated  as of May  15,  1998  (as  the  same  may be
modified,  amended,  supplemented  and/or  restated  from  time  to  time,  this
"Agreement"),   between  TII  Industries,  Inc.,  a  Delaware  corporation  (the
"Company"), and Harris Trust and Savings Bank, a Illinois corporation, as Rights
Agent (the "Rights Agent").

         The Board of  Directors  of the Company has  authorized  and declared a
dividend distribution of one Right for each share of Common Stock of the Company
outstanding  as of the  Opening  of  Business  (as such  terms  are  hereinafter
defined) on May 21, 1998 (the "Record Date"), and has further authorized (i) the
issuance  of one Right with  respect  to each  share of Common  Stock that shall
become  outstanding  between  the Opening of Business on the Record Date and the
earliest  of the  Distribution  Date (as such term is defined in Section 3), the
Redemption  Date and the Final  Expiration  Date (as such  terms are  defined in
Section  7) and (ii) in  certain  circumstances  provided  in  Section  22,  the
issuance  of one Right with  respect  to each  share of Common  Stock that shall
become  outstanding  between  the  Distribution  Date  and  the  earlier  of the
Redemption Date and the Final Expiration Date, each Right initially representing
the right to purchase one  one-thousandth  of a share of a Preferred Share, upon
the terms and subject to the conditions herein set forth (the "Rights").

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

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

              (a)  "Acquiring  Person"  shall  mean  any  Person  who or  which,
together  with  all  Affiliates  and  Associates  of such  Person,  shall be the
Beneficial Owner of 20% or more of the shares of Common Stock then  outstanding,
but shall not include any Exempt Person or any  Grandfathered  Stockholders  (as
each term is hereinafter  defined).  Notwithstanding  the  foregoing,  no Person
shall become an "Acquiring Person" as the result of an acquisition of beneficial
ownership of shares of Common Stock by the Company  that, by reducing the number
of shares of Common Stock (or securities  convertible  into or exchangeable  for
shares of Common  Stock)  outstanding,  increases  the  percentage  of shares of
Common Stock beneficially owned by such Person (together with all Affiliates and
Associates  of such  Person) to 20% or more of the  shares of Common  Stock then
outstanding;  provided,  however, that if any Person (other than Exempt Persons)
(together  with all  Affiliates  and Associates of such Person) shall become the
Beneficial  Owner of 20% or more of the shares of Common Stock then  outstanding
by  reason of share  purchases  by the  Company  and  shall,  after  such  share
purchases by the Company,  become the Beneficial Owner of any additional  shares
of Common Stock of the Company, then such Person shall be an "Acquiring Person."
Notwithstanding  the  foregoing,  if the  Board  of  Directors  of  the  Company
determines  in good  faith that a Person who would  otherwise  be an  "Acquiring
Person" as defined  pursuant to the first  sentence of this  paragraph  (a), has
become such inadvertently,  and such Person divests as promptly as practicable a
sufficient  number of shares of Common Stock so 


                                       1

<PAGE>

that such Person would no longer be an "Acquiring  Person," as defined  pursuant
to the foregoing  provisions of this  paragraph (a), then such Person shall not,
solely  as a  result  of  such  inadvertent  acquisition,  be  deemed  to  be an
"Acquiring Person" for any purpose of this Agreement.

              (b) "Affiliate" and "Associate" shall have the respective meanings
ascribed  to such  terms in Rule  12b-2 of the  General  Rules  and  Regulations
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), as such rule is in effect on the Record Date.

              (c) A Person shall be deemed the  "Beneficial  Owner" of and shall
be deemed  to  "beneficially  own,"  and  shall be  deemed  to have  "beneficial
ownership" of, any securities:

                   (i) that such Person,  or any of such Person's  Affiliates or
       Associates, directly or indirectly has

                        (A)  the  right  to  acquire   (whether  such  right  is
            exercisable  immediately or only after the passage of time) pursuant
            to any agreement,  arrangement or  understanding  (whether or not in
            writing),  or upon  the  exercise  of  conversion  rights,  exchange
            rights,  rights  (other than the  Rights),  warrants or options,  or
            otherwise;  provided, however, that a Person shall not be deemed the
            Beneficial Owner of, or to beneficially own (1) securities  tendered
            pursuant to a tender or exchange  offer made by or on behalf of such
            Person or any of such Person's  Affiliates or Associates  until such

after the date of this  Agreement  and prior to the issuance of the Rights) (the

(x) the Rights will be evidenced  (subject to the provisions of paragraph (b) of
this Section 3) by the certificates for shares of Common Stock registered in the

of the Company,  send by  first-class,  insured,  postage-prepaid  mail, to each
record  holder  of shares of  Common  Stock as of the Close of  Business  on the

after the Distribution Date (unless  otherwise  provided with respect thereto as
aforesaid),  to the record  


                                       4
<PAGE>

holder of such shares of Common Stock on the date of issuance, at the address of
such  holder  shown on the  records  of the  Company,  a Right  Certificate,  in
substantially  the form of  Exhibit  B,  evidencing  one Right for each share of
Common Stock so held,  subject to adjustments as provided  herein.  In the event
that an  adjustment  in the number of Rights per share of Common  Stock has been
made pursuant to Section 11(i) hereof,  at the time of distribution of the Right
Certificates,  the  Company  may make the  necessary  and  appropriate  rounding
adjustments (in accordance with Section 14(a) hereof) so that Right Certificates
representing  only whole numbers of Rights are  distributed  and cash is paid in
lieu of any fractional Rights. As of and after the Distribution Date, the Rights
will be evidenced solely by such Right Certificates.

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

              (c)  Rights  shall be issued in  respect  of all  shares of Common
Stock  which  are  issued  (whether  originally  issued  or  delivered  from the
Company's  treasury)  after the Opening of Business on the Record Date but prior
to the earlier of the Distribution  Date, the Redemption Date, the Exchange Date
or the Final Expiration Date; provided,  however, that Rights may be issued with
respect to shares of Common Stock that become outstanding after the Distribution
Date and prior to the earlier of the Redemption  Date, the Exchange Date and the
Final  Expiration  Date  in  accordance  with  Section  22  of  this  Agreement.
Certificates  for shares of Common Stock issued after the Opening of Business on
the Record Date but prior to the earlier of the  Distribution  Date or the Final
Expiration Date  (including,  without  limitation,  reacquired  shares of Common
Stock  referred  to in the last  sentence  of this  paragraph  (c))  shall  have
impressed on, printed on, written on or otherwise  affixed to them the following
legend:

              This  certificate  also  evidences and entitles the
              holder  hereof to certain  Rights as set forth in a
              Rights Agreement between TII Industries,  Inc. (the
              "Company")  and Harris Trust and Savings  Bank,  as
              Rights Agent, dated as of May 15, 1998 (the "Rights
              Agreement"),   the  terms  of  which   are   hereby
              incorporated  herein  by  reference  and a copy  of
              which is on file at the principal executive offices
              of the Company. Under certain circumstances, as set
              forth in the Rights Agreement,  such Rights will be
              evidenced  by  separate  certificates  and  will no
              longer  be  evidenced  by  this  certificate.   The
              Company will mail to the holder of this certificate
              a copy of the Rights Agreement, as in effect on the
              date 


                                5

              of  mailing,   without  charge  promptly  following
              receipt  of  a  written  request  therefor.   Under
              certain circumstances, Rights beneficially owned by
              Acquiring  Persons or  Associates  or Affiliates of
              Acquiring Persons (as such terms are defined in the
              Rights Agreement) and any subsequent holder of such
              Rights may become null and void.

With  respect to such  certificates  bearing  the  foregoing  legend,  until the
Distribution  Date,  the  Rights  associated  with the  shares of  Common  Stock
represented by such certificates shall be evidenced by such certificates  alone,
with or without the foregoing legend, and registered holders of shares of Common
Stock shall also be the  registered  holders of the associated  Rights,  and the
transfer  of any of such  certificates,  with or without the  foregoing  legend,
shall also  constitute the transfer of the Rights  associated with the shares of
Common Stock  represented  by such  certificates.  In the event that the Company
purchases  or acquires  any shares of Common Stock after the Opening of Business
on the Record Date but prior to the  Distribution  Date,  any Rights  associated
with such shares of Common  Stock shall be deemed  canceled  and retired so that
the Company  shall not be entitled to exercise  any Rights  associated  with the
shares of Common Stock which are no longer outstanding.

          Section 4. Form of Right Certificates. (a) The Right Certificates (and
the forms of election to purchase  shares and of assignment to be printed on the
reverse  thereof) shall be  substantially  in the form of Exhibit B 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 any national securities  association on whose
interdealer  quotation system the Rights may from time to time be authorized for
quotation,  or to conform to usage. The Right Certificates shall be in a machine
printable  format and in a form  reasonably  satisfactory  to the Rights  Agent.
Subject to the provisions of Section 22, the Right  Certificates that are issued
in respect of shares of Common Stock that were issued and  outstanding as of the
Opening of Business on the Record Date shall be dated as of the Record Date, and
all Right  Certificates  that are issued in  respect  of other  shares of Common
Stock  shall be dated as of the  respective  dates of issuance of such shares of
Common  Stock,  and in either  case on their  faces  shall  entitle  the holders
thereof to purchase such number of one-thousandths of a Preferred Share as shall
be set forth therein at the price per one  one-thousandth  of a Preferred  Share
set forth therein (the "Purchase Price"),  but the number and type of securities
purchasable  upon exercise of each Right and the Purchase Price shall be subject
to adjustment as provided herein.

              (b) Any Right Certificate  issued pursuant to Section 3 or Section
22 that  represents  Rights which are null and void  pursuant to Section 7(e) of
this  Agreement,  and any Right  Certificate  issued  pursuant  to  Section 6 or
Section 11 hereof upon  transfer,  exchange,  replacement  or  adjustment of any
other Right  Certificate  referred to in this  sentence,  shall  contain (to the
extent feasible) the following legend:

              The Rights  represented  by this Right  Certificate
              are or were beneficially  owned by a Person who was
              or became an Acquiring Person or an Affiliate or an
              Associate of an Acquiring Person (as


                                6

<PAGE>

              such terms are  defined  in the Rights  Agreement).
              Accordingly,  this Right Certificate and the Rights
              represented hereby are null and void.

          The absence of the foregoing legend on any Right  Certificate shall in
no way affect any of the other provisions of this Agreement,  including, without
limitation,  the  provisions  of Section 7(e).  The Company  shall  instruct the
Rights Agent in writing of the Rights which should be so legended.

          Section  5.   Countersignature   and   Registration.   (a)  The  Right
Certificates  shall be executed on behalf of the  Company by its  chairman,  its
president or a vice president,  either manually or by facsimile  signature,  and
have affixed  thereto the  Company's  seal or a facsimile  thereof that shall be
attested by the  secretary,  or an  assistant  secretary  or  treasurer,  of the
Company, either manually or by facsimile signature. The Right Certificates shall
be  manually  countersigned  by the Rights  Agent and shall not be valid for any
purpose  unless so  countersigned.  In case any officer of the Company who shall
have signed any of the Right  Certificates shall cease to be such officer of the
Company before countersignature by the Rights Agent and issuance and delivery by
the Company, such Right Certificates,  nevertheless, may be countersigned by the
Rights  Agent,  and issued and  delivered by the Company with the same force and
effect as though the person who signed such Right Certificates had not ceased to
be such  officer  of the  Company;  and any Right  Certificate  may be signed on
behalf of the Company by any person who, at the actual date of the  execution of
such Right  Certificate,  shall be a proper  officer of the Company to sign such
Right  Certificate,  although  at the  date  of the  execution  of  this  Rights
Agreement any such person was not such an officer.

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

          Section 6.  Transfer,  Split Up,  Combination  and  Exchange  of Right
Certificates;  Mutilated,  Destroyed,  Lost or Stolen  Right  Certificates.  (a)
Subject to the provisions of Section 4(b),  Section 7(e), Section 11 and Section
14, at any time after the Close of Business on the Distribution  Date, and at or
prior to the Close of  Business  on the  earlier of the  Redemption  Date or the
Final  Expiration  Date,  any Right  Certificate  or Right  Certificates  may be
transferred,  split up,  combined or exchanged for another Right  Certificate or
Right Certificates, entitling the registered holder to purchase a like number of
one  one-thousandths  of a Preferred Share (or other securities or other assets,
as the case may be) as the Right Certificate or Right  Certificates  surrendered
then  entitled  such  holder to  purchase.  Any  registered  holder  desiring to
transfer,  split up, combine or exchange any Right  Certificate  shall make such
request in writing  delivered to the Rights Agent, and shall surrender the Right
Certificate  or Right  Certificates  to be  transferred,  split up,  combined or
exchanged,  with the form of assignment and certificate  appropriately executed,
at the office of the Rights  Agent  designated  for such  purpose.  Neither  the
Rights Agent nor the Company  shall be  obligated to take any action  whatsoever
with respect to the transfer of any such surrendered Right Certificate until the
registered  holder shall have completed and signed the certificate  contained in
the form of assignment on the reverse side of such Right  Certificate  and shall
have provided such additional  evidence of the identity of the Beneficial  Owner
(or former Beneficial Owner) or Affiliates or Associates  thereof as the Company
shall reasonably request.  Thereupon the Rights Agent shall,  subject to Section
4(b),  Section 7(e),  Section 


                                       7

<PAGE>

11 and Section 14,  countersign  and  deliver to the person  entitled  thereto a
Right  Certificate or Right  Certificates,  as the case may be, as so requested.
The Company may require  payment by the holder of a Right  Certificate  of a sum
sufficient  to cover  any tax or  governmental  charge  that may be  imposed  in
connection  with any  transfer,  split  up,  combination  or  exchange  of Right
Certificates.

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

          Section 7.  Exercise of Rights,  Purchase  Price;  Expiration  Date of
Rights.  (a)  Subject  to  Section  7(e),  the  registered  holder  of any Right
Certificate  may  exercise  the Rights  evidenced  thereby  (except as otherwise
provided   herein,   including,   without   limitation,   the   restrictions  on
exercisability  set forth in Section 9(c), Section 11(a)(iii) and Section 23(a))
in whole or in part at any time after the  Distribution  Date upon  surrender of
the Right Certificate, with the form of election to purchase on the reverse side
thereof  duly  executed,  to the Rights  Agent at the office of the Rights Agent
designated  for such purpose,  together with payment of the Purchase  Price with
respect to the total  number of one  one-thousandths  of a  Preferred  Share (or
other  securities,  cash or other  assets,  as the case may be) as to which  the
Rights are  exercised,  at or prior to the earliest of (i) the Close of Business
on May 15, 2008 (the "Final Expiration Date"), (ii) the time at which the Rights
are  redeemed as provided in Section 23 (the  "Redemption  Date"),  or (iii) the
time at which such  Rights are  exchanged  as provided in Section 24 hereof (the
"Exchange Date").

              (b) The Purchase Price for each one  one-thousandth of a Preferred
Share  pursuant to the exercise of a Right shall  initially  be $30,  subject to
adjustment  from time to time as  provided  in  Sections 11 and 13, and shall be
payable in lawful  money of the United  States of America,  subject to paragraph
(c) below.

              (c) Upon receipt of a Right Certificate  representing  exercisable
Rights,  with the form of election to purchase  duly  executed,  accompanied  by
payment of the Purchase Price for the Preferred  Shares (or other  securities or
other  assets,  as the case may be) to be  purchased  and an amount equal to any
applicable  transfer  tax  required  to be paid  by the  holder  of  such  Right
Certificate  in  accordance  with  Section  6 hereof,  the  Rights  Agent  shall
thereupon  promptly (i) (A) requisition  from any transfer agent for such shares
(or make  available,  if the Rights Agent is the transfer agent for such shares)
certificates for the total number of shares of Preferred Shares to be purchased,
and the Company hereby irrevocably  authorizes its transfer agent to comply with
all such requests, or (B) if the Company shall have elected to deposit the total
number of Preferred Shares issuable upon exercise of the Rights hereunder with a
depository  agent,  requisition from the depository  agent  depository  receipts
representing such number of one one-thousandths of Preferred Shares as are to be
purchased (in which case  certificates for the Preferred  Shares  represented by
such  receipts  shall be  deposited by the  transfer  agent with the  depository
agent) and the Company hereby  directs the depository  agent to comply with such
request, (ii) when appropriate,  requisition from the Company the amount of cash
to be paid in lieu of issuance of  fractional  interests in shares in accordance
with  Section  14,  (iii)  after  receipt  of such  


                                       8

<PAGE>

certificates or depository  receipts,  cause the same to be delivered to or upon
the order of the registered holder of such Right Certificates registered in such
name or names as may be  designated  by such  holder and (iv) when  appropriate,
after receipt,  deliver such cash to or upon the order of the registered  holder
of such Right Certificate. The payment of the Purchase Price (as such amount may
be reduced  pursuant to Section  11(a)(iii)) may be made in cash or by certified
or bank check or money order  payable to the order of the Company.  In the event
the Company is obligated to issue other securities  (including  shares of Common
Stock) of the Company or  distribute  other  property  pursuant to Section 11(a)
hereof,  the Company  will make all  arrangements  necessary  so that such other
securities or property are available for  distribution  by the Rights Agent,  if
and when appropriate.

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

              (e)  Notwithstanding  anything to the contrary in this  Agreement,
from and  after  the  first  occurrence  of any  Triggering  Event,  any  Rights
beneficially owned by (i) any Acquiring Person (or any Associate or Affiliate of
an Acquiring Person), (ii) a transferee of an Acquiring Person (or any Associate
or Affiliate  of an  Acquiring  Person)  which  becomes a  transferee  after the
Acquiring  Person becomes such, or (iii) a transferee of an Acquiring Person (or
any  Associate or  Affiliate  of an  Acquiring  Person) 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 (or any  Associate or  Affiliate  of such  Acquiring
Person) to  holders of equity  interests  in such  Acquiring  Person (or of such
Associate or Affiliate) or to any Person with whom the Acquiring  Person has any
agreement, arrangement or understanding regarding the transferred Rights, or (B)
a transfer that the Board of Directors of the Company 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 be null and void without any further
action,  and no holder of such  Rights  shall  have any rights  whatsoever  with
respect  to such  Rights,  whether  under any  provision  of this  Agreement  or
otherwise.  The  Company  shall use all  reasonable  efforts to ensure  that the
provisions  of this Section 7(e) and Section 4(b) are complied  with,  but shall
have no liability to any holder of Rights or any other Person as a result of its
failure to make any  determination  under this Section 7(e) or such Section 4(b)
with  respect  to any  Acquiring  Person  or an  Associate  or  Affiliate  of an
Acquiring Person or their transferees.

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

          Section 8.  Cancellation  and Destruction of Right  Certificates.  All
Right Certificates surrendered for the purpose of exercise,  transfer, split up,
combination  or exchange  shall,  if surrendered to the Company or to any of its
agents,  be delivered to the Rights Agent for  cancellation or in canceled form,
or, if  surrendered  to the Rights Agent,  shall be canceled by it, and no Right
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
any of the provisions of this Rights Agreement. 


                                        9

<PAGE>

The Company shall deliver to the Rights Agent for  cancellation  and retirement,
and the Rights  Agent  shall so cancel and retire,  any other Right  Certificate
purchased or acquired by the Company  otherwise than upon the exercise  thereof.
The Rights Agent shall deliver all canceled Right Certificates to the Company.

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

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

              (c) The Company shall use its best efforts to (i) file, as soon as
is  practicable  following  the earliest  date after the first  occurrence  of a
Triggering  Event,  or as soon as is required by law following the  Distribution
Date, as the case may be, a registration  statement  under the Securities Act of
1933,  as  amended  (the  "Securities  Act"),  with  respect  to the  securities
purchasable upon exercise of the Rights on an appropriate  form, (ii) cause such
registration  statement to become  effective as soon as  practicable  after such
filing and (iii) cause such  registration  statement to remain effective (with a
prospectus at all times meeting the  requirements  of the Securities  Act) until
the earlier of (A) the date as of which the Rights are no longer exercisable for
such securities  pursuant to Section  11(a)(ii),  (B) the Redemption Date or (C)
the Final  Expiration  Date.  The  Company  will also take such action as may be
appropriate  under, or to ensure  compliance  with, the securities or "blue sky"
laws of the various states in connection with the  exercisability of the Rights.
Notwithstanding  any  provision of this  Agreement to the  contrary,  the Rights
shall not be exercisable in any  jurisdiction if the exercise  thereof shall not
be permitted under applicable law.

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

              (e) The Company  further  covenants  and agrees  that,  subject to
Section 6 and Section 7(c), it will pay when due and payable any and all federal
and state  transfer  taxes and  charges  that may be  payable  in respect of the
issuance or delivery of the Right  Certificates or of any shares of Common Stock
upon the exercise of Rights. The Company shall not, however,  be required to pay
any  transfer  tax that may be payable in respect of any transfer or delivery of
Right  Certificates  to a Person  other  than,  or the  issuance  or delivery of
certificates  or  depository  receipts  for the shares of Common Stock in a name
other than that of, the registered  holder of the Right  Certificate  evidencing
Rights  surrendered  for  exercise  or to issue or deliver any  certificates  or
depository  receipts  for the shares of 


                                       10

<PAGE>

Common  Stock upon the exercise of any Rights until any such tax shall have been
paid (any such tax being payable by the holder of such Right  Certificate at the
time  of  surrender)  or  until  it  has  been   established  to  the  Company's
satisfaction that no such tax is due.

          Section 10.  Preferred  Shares Record Date.  Each person in whose name
any certificate for Preferred  Shares (or Common Stock and/or other  securities,
as the case may be) is issued upon the exercise of Rights shall for all purposes
be deemed to have  become  the  holder of record of such  Preferred  Shares  (or
Common Stock and/or other  securities,  as the case may be) represented  thereby
on,  and such  certificate  shall  be  dated,  the date  upon  which  the  Right
Certificate  evidencing  such  Rights was duly  surrendered  and  payment of the
Purchase Price (and any applicable transfer taxes) was made; provided,  however,
that if the  date  of such  surrender  and  payment  is a date  upon  which  the
Preferred Shares (or Common Stock and/or other  securities,  as the case may be)
transfer  books of the Company are closed,  such person  shall be deemed to have
become the record holder of such shares  (fractional  or otherwise) on, and such
certificate  shall be  dated,  the next  succeeding  Business  Day on which  the
Preferred Shares (or Common Stock and/or other  securities,  as the case may be)
transfer  books of the  Company  are open.  Prior to the  exercise of the Rights
evidenced  thereby,  the holder of a Right  Certificate,  as such,  shall not be
entitled  to any rights of a  stockholder  of the  Company  with  respect to the
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 of Shares or Number
of Rights. The Purchase Price, the number and kind of securities covered by each
Right and the number of Rights  outstanding  are subject to adjustment from time
to time as provided in this Section 11.

              (a) (i) In the event the Company  shall at any time after the date
of this  Agreement  (A) declare a dividend on the  Preferred  Shares  payable in
Preferred Shares,  (B) subdivide the outstanding  Preferred Shares,  (C) combine
the outstanding  Preferred Shares into a smaller number of Preferred  Shares, or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such  reclassification  in connection with a consolidation
or merger in which the  Company is the  continuing  or  surviving  corporation),
except as  otherwise  provided  in this  Section  11(a) 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  and kind of shares of capital  stock  issuable  on such  date,  shall be
proportionately  adjusted so that the holder of any Right  exercised  after such
time shall be  entitled to receive  the  aggregate  number and kind of shares of
capital stock that, if such Right had been exercised  immediately  prior to such
date and at a time when the  Preferred  Shares (or  Common  Stock  and/or  other
securities,  as the case may be) transfer  books of the Company were open,  such
holder  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 the exercise
of one  Right be less than the  aggregate  par  value of the  securities  of the
Company  issuable  upon the  exercise  thereof.  If an event  occurs  that would
require an adjustment  under both this 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,  at any time after the date of
       this Agreement,  is or becomes an Acquiring Person, then proper provision
       shall be made so that each  holder  of a Right,



                                       11

<PAGE>

       except as  provided in Section  7(e),  shall  thereafter  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 shares of
       Common Stock as shall equal the result  obtained by (x)  multiplying  the
       then current  Purchase  Price by the number of one  one-thousandths  of a
       Preferred  Share for which a Right was exercisable  immediately  prior to
       the first occurrence of the Section 11(a)(ii) Event and (y) dividing that
       product by 50% of the  current  per share  market  price of the shares of
       Common Stock  (determined  pursuant to Section  11(d)) on the date of the
       occurrence  of the  Section  11(a)(ii)  Event  (such  number of shares is
       herein  called the  "Adjustment  Shares");  provided,  however,  that the
       Purchase Price and number of Adjustment  Shares shall be further adjusted
       as provided in this  Agreement to reflect any event  occurring  after the
       date of such first occurrence.

                   (iii) In the event that,  after the date of the occurrence of
       such a Section  11(a)(ii)  Event,  the  number of shares of Common  Stock
       which is authorized by the Company's certificate of incorporation but not
       outstanding  or  reserved  for  issuance  for  purposes  other  than upon
       exercise of the Rights is not  sufficient  to permit the exercise in full
       of the Rights,  the Company  shall:  (A)  determine the excess of (1) the
       value of the  Adjustment  Shares in  accordance  with  Section  11(a)(ii)
       issuable upon the exercise of a Right (the "Current  Value") over (2) the
       Purchase Price (such excess is herein called the "Spread"),  and (B) with
       respect to each Right,  make  adequate  provision to  substitute  for the
       Adjustment Shares upon exercise of the Rights,  (1) cash, (2) a reduction
       in the  Purchase  Price,  (3)  shares  of  Common  Stock  of the  same or
       different  class or other equity  securities  of the Company  (including,
       without limitation, shares, or units of shares, of common stock which the
       Board of  Directors of the Company has deemed to have  substantially  the
       same  economic  value as shares of Common  Stock (such shares or units of
       shares  of  Common  Stock  are  referred  to  herein  as  "common   stock
       equivalents")),  (4) debt securities of the Company, (5) other assets, or
       (6) any  combination of the foregoing  having an aggregate value equal to
       the Current Value,  where such aggregate value has been determined by the
       Board of Directors  of the Company  based upon the advice of a nationally
       recognized  investment banking firm selected by the Board of Directors of
       the  Company;  provided,  however,  if the  Company  shall  not have made
       adequate  provision to deliver value  pursuant to clause (B) above within
       thirty (30) days  following  the later of (x) the first  occurrence  of a
       Section  11(a)  Event  and (y) the date on which the  Company's  right of
       redemption  pursuant to Section 23(a) expires,  then the Company shall be
       obligated  to deliver,  upon the  surrender  for  exercise of a Right and
       without requiring  payment of the Purchase Price,  shares of Common Stock
       (to the extent  available)  and then,  if necessary,  cash,  which shares
       and/or cash have an aggregate value equal to the Spread.

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



                                       12

<PAGE>

offered)  would  purchase at such current  market price and the  denominator  of
which shall be the number of Preferred  Shares  outstanding  on such record date
plus the number of  additional  Preferred  Shares  and/or  equivalent  preferred
shares to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible);  provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the  aggregate par value of the shares of capital stock of the Company
issuable upon the exercise of one Right. In case such subscription  price may be
paid in a consideration part or all of which shall be in a form other than cash,
the value of such  consideration  shall be as  determined  in good  faith by 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
and the holders of Rights.  Preferred Shares owned by or held for the account of
the  Company  shall  not be  deemed  outstanding  for the  purpose  of any  such
computation.  Such adjustment shall be made successively  whenever such a record
date is fixed,  and in the event that such rights or warrants are not so issued,
the Purchase Price shall be adjusted to be the Purchase Price that would then be
in effect if such record date had not been fixed.

              (c) In case the Company  shall fix a record date for the making of
a  distribution  to  all  holders  of  Preferred  Shares   (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 or
assets  (other than a regular  quarterly  cash  dividend  out of the earnings or
retained  earnings of the Company or a dividend payable in Preferred  Shares) 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 per share  market
price of a Preferred  Share (as  determined  pursuant to Section  11(d)) on such
record date less the fair market value (as determined in good faith by the Board
of  Directors  of the  Company,  whose  determination  shall be  described  in a
statement  filed with the Rights  Agent and shall be binding on the Rights Agent
and the holders of the Rights) of the portion of the cash,  assets or  evidences
of indebtedness so to be distributed or of such subscription  rights or warrants
applicable  to a  Preferred  Share and the  denominator  of which  shall be such
current per share market price of a Preferred  Share (as determined  pursuant to
Section 11(d)) provided, however, that in no event shall the consideration to be
paid upon the exercise of one Right be less than the  aggregate par value of the
shares of capital stock of the Company  issuable upon the 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 that would then be in
effect if such record date had not been fixed.

              (d) (i) For the purpose of any computation  hereunder  (other than
computations made pursuant to Section 11(a)(iii) hereof), the "current per share
market  price" of the  shares of Common  Stock on any date shall be deemed to be
the average of the daily closing prices per share of such shares of Common Stock
for the  thirty  (30)  consecutive  Trading  Days (as such  term is  hereinafter
defined)  immediately  prior to such date, and for purposes of computations made
pursuant to Section  11(a)(iii)  hereof, the "current per share market price" of
shares of Common  Stock on any date  shall be  deemed to be the  average  of the
daily  closing  prices per share of such shares of Common Stock for the ten (10)
consecutive  Trading Days immediately  following such date;  provided,  however,
that in the event  that the  current  per share  market  price of the  shares of
Common Stock is determined  during a period  following the  announcement  by the
issuer of such shares of Common Stock of (1) a dividend or  distribution on such
shares of Common  Stock  payable in such  shares of Common  Stock or  securities
convertible into such shares of Common Stock (other than the Rights), or (2) any
subdivision, 


                                       13

<PAGE>

combination or reclassification of such shares of Common Stock, and prior to the
expiration  of thirty (30) Trading  Days, or ten (10) Trading Days, as set forth
above,  after the  ex-dividend  date for such dividend or  distribution,  or the
record date for such subdivision, combination or reclassification,  then, and in
each such case,  the  current  per share  market  price  shall be  appropriately
adjusted to 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 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 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 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 shares of
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 shares of Common Stock,  the fair
value of the shares of Common Stock on such date as  determined in good faith by
the Board of  Directors of the Company  shall be used.  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
shares  of  Common  Stock are not  publicly  held or not so  listed  or  traded,
"current  per  share  market  price"  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.

                   (ii)  For  the  purpose  of any  computation  hereunder,  the
       "current  per  share  market  price"  of the  Preferred  Shares  shall be
       determined in accordance  with the method set forth in Section  11(d)(i).
       If the Preferred Shares are not publicly  traded,  the "current per share
       market price" of the Preferred Shares shall be conclusively  deemed to be
       the current per share  market  price of the Common  Shares as  determined
       pursuant to Section 11(d)(i) (appropriately adjusted to reflect any stock
       split,  stock dividend or similar  transaction  occurring  after the date
       hereof),  multiplied by one hundred. If neither the Common Shares nor the
       Preferred  Shares are publicly held or so listed or traded,  "current per
       share market  price" shall mean the fair value per share as determined in
       good  faith  by  the  Board  of  Directors  of  the  Corporation,   whose
       determination  shall be  described  in a statement  filed with the Rights
       Agent and shall be binding on the Rights Agent.

              (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 that by reason of this Section 11(e) are not required to be
made  shall  be  carried  forward  and  taken  into  account  in any  subsequent
adjustment.  All calculations under this Section 11 shall be made to the nearest
cent  or  to  the  nearest  one   one-thousandth   of  a  Preferred   Share  one
ten-thousandth  of a any other security.  Notwithstanding  the first sentence of
this Section 11(e), any adjustment  required by this Section 11 shall be made no
later than 


                                       14

<PAGE>

the  earlier  of (i)  three  (3) years  from the date of the  transaction  which
mandates such adjustment or (ii) the Final Expiration Date.

              (f) If as a result  of an  adjustment  made  pursuant  to  Section
11(a)(ii) 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
the Preferred  Shares,  thereafter the number of such other shares so receivable
upon exercise of any Right shall be subject to adjustment from time to time in a
manner and on terms as nearly  equivalent as practicable to the provisions  with
respect to the shares contained in Section 11(a),  (b), (c), (e), (g), (h), (i),
(j), (k) and (m) and the provisions of Sections 7, 9, 10, 13 and 14 with respect
to the Common 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 the Preferred  Shares
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  Sections  11(b)  and  (c),  each  Right
outstanding  immediately prior to the making of such adjustment shall thereafter
evidence the right to purchase,  at the adjusted  Purchase Price, that number of
one   one-thousandths   of  a  Preferred   Share   (calculated  to  the  nearest
ten-thousandth)   obtained   by  (i)   multiplying   (x)  the   number   of  one
one-thousandths  of a Preferred  Share covered by a Right  immediately  prior to
this  adjustment by (y) the Purchase Price in effect  immediately  prior to such
adjustment  of the Purchase  Price and (ii)  dividing the product so obtained by
the Purchase Price in effect  immediately  after such adjustment of the Purchase
Price.

              (i) The Company  may elect on or after the date of any  adjustment
of the Purchase Price to adjust the number of Rights,  in  substitution  for any
adjustment in the number of one  one-thousandth of a Preferred Share purchasable
upon  the  exercise  of a  Right.  Each of the  Rights  outstanding  after  such
adjustment  of the number of Rights shall be  exercisable  for the number of one
one-thousandth  of a Preferred Share 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  Right
Certificates  have been  issued,  shall be at least ten (10) days later than the
date of the public  announcement.  If Right Certificates have been issued,  upon
each  adjustment  of the number of Rights  pursuant to this Section  11(i),  the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Rights on such record date Right Certificates  evidencing,  subject to
Section 14, the  additional  Rights to which such holders shall be entitled as a
result of such adjustment,  or, at the option of the Company,  shall cause to be
distributed to such holders of record in  substitution  and  replacement for the
Right  Certificates  held by such holders prior to the date of  adjustment,  and
upon  surrender  thereof,  if required by the  Company,  new Right  Certificates
evidencing  all the Rights to which such  holders  shall be entitled  after such
adjustment.  Right  Certificates so to be distributed shall be issued,  executed
and 


                                       15

<PAGE>

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 Right  Certificates  on the record date specified in
the public announcement.

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

              (k)  Before  taking  any action  that  would  cause an  adjustment
reducing the Purchase  Price below the then par value,  if any, of the number of
one  one-thousandths  of a  Preferred  Share,  shares of  Common  Stock or other
securities  issuable  upon  exercise of the Rights,  the Company  shall take any
corporate action that may, in the opinion of its counsel,  be necessary in order
that the Company may  validly  and  legally  issue fully paid and  nonassessable
shares 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 Preferred  Shares,  Common Stock or other capital stock or securities of the
Company,  if any,  issuable  upon such  exercise  over and  above the  Preferred
Shares,  Common Stock or 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  (fractional  or  otherwise)  upon the
occurrence of the event requiring such adjustment.

              (m) Anything in this  Section 11 to the contrary  notwithstanding,
the Company shall be entitled to make such  reductions in the Purchase Price, in
addition to those adjustments  expressly  required by this Section 11, as and to
the extent  that in their  good faith  judgment  the Board of  Directors  of the
Company shall determine to be advisable in order that any (i)  consolidation  or
subdivision  of the  Preferred  Shares,  (ii)  issuance  wholly  for cash of any
Preferred  Shares at less than the current market price,  (iii) issuance  wholly
for cash of  Preferred  Shares  or other  securities  that by  their  terms  are
convertible into or exchangeable for Preferred  Shares,  (iv) stock dividends or
(v)  issuance of rights,  options or warrants  referred to  hereinabove  in this
Section 11,  hereafter  made by the Company to holders of its  Preferred  Shares
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  complies with Section
11(o)  hereof),  (ii) merge with or into or engage in a share  exchange with any
other Person  (other than a  Subsidiary  of the Company in a  transaction  which
complies  with 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 complies with Section 11(o) hereof),
if (x) at the time of or immediately  after such  consolidation,  merger,  share
exchange  or sale  there  are any  rights,  warrants,  or other  


                                       16

<PAGE>

instruments  or  securities  outstanding  or  agreements  in effect  which would
substantially  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,  share exchange or sale, the  stockholders  of the
Person who constitutes,  or would constitute, the "Principal Party" for purposes
of Section 13(a) shall have received a distribution of Rights  previously  owned
by such Person or any of its  Affiliates  or  Associates.  The Company shall not
consummate any such  consolidation,  merger, sale or transfer unless prior there
to the Company and such other  Person shall have  executed and  delivered to the
Rights Agent a Supplemental  agreement  evidencing  compliance with this Section
11(h).

              (o) The Company  covenants and agrees that, after the Distribution
Date, it shall not,  except as permitted by Section 23, Section 24 or Section 27
hereof,  take (or permit any  Subsidiary to take) any action if at the time such
action is taken it is  reasonably  foreseeable  that such action  will  diminish
substantially or otherwise eliminate the benefits intended to be afforded by the
Rights.

              (p) In the event that at any time,  after the date of this  Rights
Agreement and prior to the  Distribution  Date, the Company shall (i) declare or
pay any dividend on its Shares of Common  Stock  payable in its Shares of Common
Stock or (ii) effect a subdivision,  combination or  consolidation of its Shares
of Common Stock (by  reclassification  or otherwise than by payment of dividends
in its  Shares of Common  Stock)  into a greater  or lesser  number of shares of
Common Stock, then in any such case (A) the number of one  one-thousandths  of a
Preferred Share  purchasable after such event upon proper exercise of each Right
shall be  determined  by  multiplying  the  number of one  one-thousandths  of a
Preferred  Share so purchasable  immediately  prior to such event by a fraction,
the  numerator  of which is the  number of Shares  of Common  Stock  outstanding
immediately  before such event and the denominator of which is the number Shares
of Common Stock outstanding  immediately after such event, and (B) each Share of
Common Stock outstanding immediately prior to such event had issued with respect
to it.  The  adjustments  provided  for in this  Section  11 (p)  shall  be made
successively whenever such a dividend is declared or paid of such a subdivision,
combination or consolidation is effected.

              (q) 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 consolidate with, or merge with or into, any
other  Person for the primary  purpose of a change of  domicile of the  Company,
and, in connection  with such  consolidation  or merger,  all of the outstanding
shares of Common Stock shall be changed  into or exchanged  for shares of Common
Stock  of the  surviving  corporation  of  such  consolidation  or  merger  (the
"Surviving  Corporation"),  then proper  provision  shall be made so that Rights
shall  be  associated   with  each  share  of  Common  Stock  of  the  Surviving
Corporation,  except as provided in Section 7(e) hereof, such that the number of
Rights  associated with each share of Common Stock of the Surviving  Corporation
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 of the Surviving Corporation which the shares of Common Stock were changed
into or exchanged for pursuant to the consolidation or merger.  Following such a
consolidation  or  merger,  this  Agreement  shall  remain  in  effect  and  all
references  to the Company  shall be deemed to be  references  to the  Surviving
Corporation.

          Section  12.  Certificate  of  Adjusted  Purchase  Price of  Number of
Shares.  Whenever an adjustment is made as provided in Section 11 or Section 13,
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
shares of Common Stock a copy of such  certificate  and (c) mail a brief summary
thereof to each  holder of record of a Right  Certificate  (or,  if prior to the
Distribution Date, to each holder of a certificate representing shares of Common
Stock) in accordance  with Section 25. The Rights Agent shall be fully protected
in relying on such  certificate  and on any adjustment  contained  therein,  and
shall not be obligated or responsible for calculating any adjustment,  nor shall
it be deemed to have knowledge of any 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,  following the Stock  Acquisition  Date,
directly or indirectly,  (x) the Company shall  consolidate  with, or merge with
and into,  any  other  Person  (other  than a  Subsidiary  of the  Company  in a
transaction which complies with Section 11(o) hereof), and the Company shall not
be the continuing or surviving  corporation of such consolidation or merger, (y)
any Person  (other  than a  Subsidiary  of the  Company in a  transaction  which
complies with Section  11(o)  hereof)  shall engage in a share  exchange with or
shall  consolidate  with,  or merge with or into,  the Company,  and the Company
shall  be the  continuing  or  surviving  corporation  of such  share  exchange,
consolidation   or  merger  and,  in  connection   with  such  share   exchange,
consolidation or merger,  all or part of the outstanding  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 (z) the Company shall sell or otherwise
transfer (or one or more of its Subsidiaries shall sell or otherwise  transfer),
in one transaction or a series of related transactions,  assets or earning power
aggregating  50% or more of the assets or earning  power of the  Company and its
Subsidiaries (taken as a whole) to any Person or Persons (other than the Company
or any  Subsidiary  of the  Company  in one or more  transactions  each of which
complies  with  Section  11(o)  hereof),  then,  and in each  such  case  proper
provision shall be made so that

                   (i) each  holder of a Right,  except as  provided  in Section
       7(e)  hereof,  shall  thereafter  have  the  right to  receive,  upon the
       exercise  thereof at the then current  Purchase Price, in accordance with
       the terms of this Agreement and in lieu of Preferred Shares,  such number
       of validly  authorized and issued,  fully paid,  nonassessable and freely
       tradeable  shares of Common Stock of the Principal Party (as such term is
       hereinafter defined), not subject to any liens,  encumbrances,  rights of
       call,  rights of first refusal 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  one-thousandths  of a  Preferred  Share for which a
       Right was  exercisable  immediately  prior to the first  occurrence  of a
       Section 13 Event (or, if a Section  11(a)(ii) Event has occurred prior to
       the first  occurrence  of a Section 13 Event,  multiplying  the  Purchase
       Price in effect  immediately  prior to the first  occurrence of a Section
       11(a)(ii) Event by the number of one one-thousandths of a Preferred Share
       for  which  a Right  was  exercisable  immediately  prior  to such  first
       occurrence of a Section 11(a)(ii) Event) and (2) dividing that product by
       50% of the current per share  market  price of the shares of Common Stock
       of such  Principal  Party  (determined  pursuant to Section 11(d)) on the
       date of consummation of such Section 13 Event;

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



                                       18
<PAGE>

                   (iii) the term "Company" shall  thereafter be deemed to refer
       to such Principal Party.

                   (iv) such Principal  Party shall take such steps  (including,
       but not limited to, the  reservation of a sufficient  number of shares of
       Common Stock) in connection with the consummation of any such transaction
       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;
       and

                   (v) the provisions of Section 11(a)(ii) hereof shall be of no
       effect following the first occurrence of any Section 13 Event.

If, in the case of a  transaction  of the kind  described  in clause  (z) of the
first  sentence of this Section  13(a),  the Person or Persons to whom assets or
earning  power  are sold or  otherwise  transferred  are  individuals,  then the
preceding sentences of this Section 13(a) shall be inapplicable, and the Company
shall  require  as a  condition  to such sale or  transfer  that such  Person or
Persons pay to each holder of a Right  Certificate,  upon its  surrender  to the
Rights  Agent  and in  exchange  therefor  (without  requiring  payment  by such
holder),  cash in the amount determined by multiplying the then current Purchase
Price  by the  number  of  shares  of  Common  Stock  for  which a Right is then
exercisable.

              (b) "Principal Party" shall mean:

                   (i) in the case of any transaction described in clause (x) or
       (y) of the first sentence of Section 13(a), the Person that is the issuer
       of any securities for or into which shares of Common Stock of the Company
       are converted in such share exchange, merger or consolidation,  and if no
       securities  are so  issued,  the Person  that is the other  party to such
       merger or consolidation; and

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

                   (iii)  provided,  however,  that in any such case, (1) if the
       shares of Common  Stock of such  Person are not at such time and have not
       been  continuously over the preceding twelve (12) month period registered
       under  Section 12 of the  Exchange  Act,  and such  Person is a direct or
       indirect Subsidiary of another Person the shares of Common Stock of which
       are and have been so  registered,  "Principal  Party" shall refer to such
       other Person;  and (2) in case such Person is a  Subsidiary,  directly or
       indirectly, of more than one Person, the shares of Common Stock 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 shares of Common
       Stock having the greatest aggregate market value.

              (c) The Company shall not  consummate  any Section 13 Event unless
the  Principal  Party shall have a  sufficient  number of  authorized  shares of
Common  Stock which have not been issued or reserved  for issuance to permit the
exercise  in full of the Rights in  accordance  with this  Section 13 and unless
prior  thereto the  Company and such  Principal  Party shall have  executed  and
delivered to the Rights Agent a supplemental  agreement  providing for the terms
set forth in  paragraphs  (a) and (b) of 


                                       19

<PAGE>

this Section 13 and further  providing  that, as soon as  practicable  after the
date of any such Section 13 Event, the Principal Party will

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

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

              (d) The  provisions  of this Section 13 shall  similarly  apply to
successive  share  exchanges,  mergers  or  consolidations  or  sales  or  other
transfers.  In the event that a Section 13 Event  shall  occur at any time after
the first  occurrence of a Section  11(a)(ii)  Event,  the Rights which have not
theretofore  been exercised shall  thereafter  become  exercisable in the manner
described in Section 13(a).

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

              (b) The  Company  shall not be  required  to issued  fractions  of
Preferred Shares (other than fractions which are one  one-thousandth or integral
multiples  of one  one-thousandth  of a 



                                       20

<PAGE>

Preferred Share) upon exercise of the Rights or to distribute certificates which
evidence  fractional  Preferred  Shares  (other  than  fractions  which  are one
one-thousandth  or  integral  multiples  of one  one-thousandth  of a  Preferred
Share).   Fractions   of   Preferred   Shares  in  integral   multiples  of  one
one-thousandth  of a Preferred  Share may, at the  election of the  Company,  be
evidenced by depositary receipts,  pursuant to an appropriate  agreement between
the Company and a depositary  selected by it; provided that such agreement shall
provide  that the  holders of such  depositary  receipts  shall have the rights,
privileges and  preferences  to which they are entitled as beneficial  owners of
the  Preferred  Shares  represented  by  such  depositary  receipts.  In lieu of
fractional  Preferred  Shares  that  are  not  one  one-thousandth  or  integral
multiples of one one-thousandth of Preferred Share, the Company shall pay to the
registered  holders of Right  Certificates at the time such Rights are exercised
as herein  provided an amount in cash equal to the same  fraction of the current
market value of one  Preferred  Share.  For the purposes of this Section 14 (b),
the current  market value of a Preferred  Share shall be the closing  price of a
Preferred  Share (as determined  pursuant to 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 event
specified  in  Section 11 giving  rise to the right to receive  shares of Common
Stock,  capital  stock  equivalents  (other  than  Preferred  Shares)  or  other
securities  upon the exercise of a Right,  the Company  shall not be required to
issue  fractions of such shares of Common Stock,  capital stock  equivalents  or
other securities upon exercise of the Rights or to distribute certificates which
evidence fractions of such shares of Common Stock,  Capital Stock equivalents or
other securities. In lieu of fractional shares or units of such shares of Common
Stock, capital stock equivalents or 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 share or unit of such  shares of Common  Stock,  capital  stock
equivalents  or other  securities.  For  purposes  of this  Section 14 (c),  the
current  market value shall be  determined in the manner set forth in Section 11
(d) hereof for the Trading Day  immediately  prior to the date of such  exercise
and, if such capital  stock  equivalent  is not traded,  each such capital stock
equivalent shall have the value of one one-thousandth of a Preferred Share.

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

          Section 15. Rights of Action.  All rights of action in respect of this
Agreement,  excepting  the  rights of action  given to the  Rights  Agent  under
Section 18 hereof, are vested in the respective  registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of the
shares of Common Stock); and any registered holder of any Right Certificate (or,
prior to the  Distribution  Date,  of the shares of Common  Stock),  without the
consent of the Rights Agent or of the holder of any other Right Certificate (or,
prior to the Distribution Date, of the shares of Common 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 Right Certificate
in the manner provided in such Right Certificate and in this Agreement.  Without
limiting the foregoing or any remedies available to the holders of Rights, it is
specifically  acknowledged that the holders of Rights would not have an adequate
remedy at law for any breach of this  Agreement and will be entitled to specific
performance of the 


                                       21

<PAGE>

obligations under, and injunctive relief against actual or threatened violations
of, the obligations of any Person subject to this Agreement.

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

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

              (b) after  the  Distribution  Date,  the  Right  Certificates  are
transferable  only on the registry  books of the Rights Agent if  surrendered at
the office of the Rights Agent  designated  for such  purpose,  duly endorsed or
accompanied by a proper  instrument of transfer and with the  appropriate  forms
and certificates fully completed and duly executed;

              (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 the  Right
Certificate  (or, prior to the  Distribution  Date, the associated  Common Stock
certificate)  is  registered  as the  absolute  owner  thereof and of the Rights
evidenced thereby  (notwithstanding any notations of ownership or writing on the
Right  Certificates or the associated  Common 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 Section  7(e),  shall be
affected by any notice to the contrary; and

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

          Section 17.  Right  Certificate  Holder Not Deemed a  Stockholder.  No
holder,  as such, of any Right  Certificate  shall be entitled to vote,  receive
dividends  or be deemed  for any  purpose  the holder of the number of shares of
Common  Stock or any other  securities  of the  Company  that may at any time be
issuable on the exercise of the Rights represented  thereby,  nor shall anything
contained  herein or in any Right  Certificate  be  construed to confer upon the
holder of any Right Certificate,  as such, any of the rights of a 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), or to receive
dividends  or  subscription  rights,  or  otherwise,  until  the Right or Rights
evidenced by such Right Certificate shall have been exercised in accordance with
the provisions hereof.

          Section 18. Concerning the Rights Agent. (a) The Company agrees to pay
to the Rights  Agent  such  compensation  as shall be agreed  upon  between  the
Company and the Rights Agent for all services rendered by it hereunder and, from
time to time, on demand of the Rights Agent, its 


                                       22

<PAGE>

reasonable  expenses  and counsel fees and other  disbursements  incurred in the
administration  and execution of this Agreement and the exercise and performance
of its duties  hereunder.  The Company also agrees to indemnify the Rights Agent
for, and to hold it harmless against, any loss, liability, or expense (including
any and all  special  indirect  or  consequential  losses or damages of any kind
(including but not limited to lost profits)),  incurred without negligence,  bad
faith or willful  misconduct on the part of the Rights Agent,  for anything done
or  omitted  by  the  Rights  Agent  in  connection   with  the  acceptance  and
administration of this Agreement,  including the costs and expenses of defending
against any claim of liability  arising  therefrom and the costs and expenses of
enforcing  the  indemnification  rights of the  Rights  Agent  pursuant  to this
Agreement.  The provisions of this Section 18(a) shall survive the expiration of
the  Rights and the  termination  of this  Agreement,  and the  resignation  and
removal of the Rights Agent.

              (b) The  Rights  Agent  shall  be  protected  and  shall  incur no
liability  for, or in respect of any action taken,  suffered or omitted by it in
connection with, its administration of this Agreement in reliance upon any Right
Certificate or certificate for shares of 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 by the proper Person or Persons and,  where  necessary,  to be
verified or acknowledged.

          Section 19. Merger or Consolidation or Change of Name of Rights Agent.
(a) Any  corporation  into which the Rights Agent or any successor  Rights Agent
may be merged or with which it may be consolidated, or any corporation resulting
from any  merger or  consolidation  to which the Rights  Agent or any  successor
Rights  Agent  shall  be a  party,  or  any  corporation  succeeding  to  all or
substantially  all the stock transfer or 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 21. In case at the time such successor  Rights Agent shall
succeed to the agency created by this Agreement,  any of the Right  Certificates
shall have been countersigned but not delivered, any such successor Rights Agent
may adopt the  countersignature of the predecessor Rights Agent and deliver such
Right  Certificates so countersigned;  and in case at that time any of the Right
Certificates shall not have been  countersigned,  any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor  Rights Agent;  and in all such cases such
Right  Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

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

          Section 20. Duties of Rights Agent.  The Rights Agent  undertakes  the
duties and  obligations  imposed by this Agreement upon the following  terms and
conditions,  and no  implied  duties  or  


                                       23

<PAGE>

obligations  shall be read into this Agreement  against the Rights Agent, by all
of which the Company and the holders of Rights Certificates, by their acceptance
thereof,  shall be bound.  Before the Rights Agent acts or refrains from acting,
the Rights Agent may consult  with legal  counsel of its  selection  (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 or  existence  of any  Acquiring
Person and the  determination  of "current per share market price") be proved or
established  by the Company prior to taking or suffering  any action  hereunder,
such  fact or  matter  (unless  other  evidence  in  respect  thereof  be herein
specifically prescribed) may be deemed to be conclusively proved and established
by a certificate  signed by any one of the chairman of the board, the president,
any vice president,  the secretary,  an assistant  secretary or the treasurer of
the Company and delivered to the Rights  Agent;  and such  certificate  shall be
full  authorization to the Rights Agent for any action taken or suffered in good
faith by it under  the  provisions  of this  Agreement  in  reliance  upon  such
certificate.

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

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

              (e) The  Rights  Agent  shall not be under any  responsibility  in
respect of the validity of this  Agreement or the execution and delivery  hereof
(except  the due  execution  hereof by the  Rights  Agent) or in  respect of the
validity or  execution  of any Right  Certificate  (except its  countersignature
thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Right  Certificate;
nor shall it be responsible for any adjustment  required under the provisions of
Section 11 or Section 13 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 change or  adjustment  (except  with  respect to the exercise of Rights
evidenced  by Right  Certificates  after  actual  notice  that  such  change  or
adjustment is required); nor shall it by any act hereunder be deemed to make any
representation  or warranty as to the authorization or reservation of any shares
of Common Stock to be issued pursuant to this Agreement or any Right Certificate
or as to whether  any  shares of Common  Stock  will,  when  issued,  be validly
authorized and issued, fully paid and nonassessable,  nor shall the Rights Agent
be  responsible  for the  legality  of the terms  hereof in its  capacity  as an
administrative agent.

              (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.


                                       24

<PAGE>

              (g) The Rights Agent is hereby  authorized  and directed to accept
instructions  with respect to the  performance of its duties  hereunder from any
one of the  chairman  of the  board,  the  president,  any vice  president,  the
secretary or the  treasurer of the  Company,  and to apply to such  officers for
advice or instructions in connection with its duties, and it shall not be liable
for any action  taken or suffered to be taken by it in good faith in  accordance
with  instructions  of any such officer or for any delay in acting while waiting
for those instructions.

              (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 peculiarly  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  (other than  employees),  and the Rights Agent
shall  not be  answerable  or  accountable  for any  act,  default,  neglect  or
misconduct  of any such  attorneys  or  agents  or for any  loss to the  Company
resulting from any such act, default, neglect or misconduct, provided reasonable
care was exercised in the selection and continued employment thereof.

              (j) If, with respect to any Right  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 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.

              (k) In  addition  to the  foregoing,  the  Rights  Agent  shall be
protected  and shall incur no liability  for, or in respect of, any action taken
or omitted by it in connection with its administration of this Agreement if such
acts  or  omissions  are in  reliance  upon  (i)  the  proper  execution  of the
certification concerning beneficial ownership appended to the form of assignment
and the form of election to purchase  attached  hereto  unless the Rights  Agent
shall have actual knowledge that, as executed,  such certification is untrue, or
(ii) the non-execution of such certification including,  without limitation, any
refusal to honor any otherwise  permissible  assignment or election by reason of
such non-execution.

              (l) 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.

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


                                       25

          The Company  agrees to give the Rights Agent prompt  written notice of
any event or ownership known to the Company which would prohibit the exercise or
transfer of the Right Certificates.

          Section 21. Change of Rights Agent.  The Rights Agent or any successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon 60 days' notice in writing mailed to the Company and to each transfer agent
of the shares of Common Stock by registered or certified  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 shares of Common Stock by  registered or
certified  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 Right  Certificate (who shall,
with such notice,  submit his Right  Certificate for inspection by the Company),
then the Rights Agent or the holder of record of any Right Certificate may apply
to any court of  competent  jurisdiction  for the  appointment  of a new  Rights
Agent. Any successor Rights Agent, whether appointed by the Company or by such a
court, shall be a corporation organized and doing business under the laws of the
United States or any state of the United States so long as such  corporation  is
authorized  to do business as a banking  institution,  is in good  standing,  is
authorized under such laws to exercise corporate trust powers, and is subject to
supervision or examination by federal or state authority, and has at the time of
its  appointment as Rights Agent a combined  capital and surplus of at least $50
million. After appointment,  the successor Rights Agent shall be vested with the
same powers,  rights,  duties and  responsibilities as if it had been originally
named as Rights Agent without  further act or deed; but the  predecessor  Rights
Agent shall deliver and transfer to the  successor  Rights Agent any property at
the time held by it  hereunder,  and execute and deliver any 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 with the predecessor
Rights Agent and each transfer  agent of the shares of Common Stock,  and mail a
notice  thereof in writing to the  holders of record of the Right  Certificates.
Failure to give any notice  provided  for in this  Section 21,  however,  or any
defect therein,  shall not affect the legality or validity of the resignation or
removal of the Rights Agent or the appointment of the successor Rights Agent, as
the case may be.

          Section 22. Issuance of New Right Certificates. Notwithstanding any of
the provisions of this  Agreement or of the Rights to the contrary,  the Company
may, at its option, issue new Right Certificates  evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the  Purchase  Price  and the  number  or kind or  class of  shares  or other
securities  or  property  purchasable  under  the  Right  Certificates  made  in
accordance  with the provisions of this  Agreement.  In addition,  in connection
with the issuance or sale of shares of Common Stock  following the  Distribution
Date and prior to the  redemption or  expiration of the Rights,  the Company (a)
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  hereinafter  issued  by the
Company,  and (b) may, in any other case, if deemed  necessary or appropriate by
the Board of Directors of the Company, issue Right Certificates representing the
appropriate number of Rights in connection with such issuance or sale; provided,
however,  that (i) no such  Right  Certificate  shall be issued  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
to the 


                                       26

<PAGE>

Person to whom such Right  Certificate  would be issued,  and (ii) no such Right
Certificate shall be issued if, and to the extent that, appropriate  adjustments
shall otherwise have been made in lieu of the issuance thereof.

          Section 23. Redemption and Termination.  (a) The Board of Directors of
the  Company  may,  at its  option,  redeem  all but not less  than all the then
outstanding  Rights at a redemption  price of $.01 per Right, as such amount may
be 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"), (i) at any time prior to the
earlier of (x) the time that any Person becomes an Acquiring  Person, or (y) the
Final  Expiration  Date,  or (ii)  within 10 days  after any  Person  becomes an
Acquiring  Person if (A) the  Acquiring  Person  notifies the Board of Directors
that such person become an Acquiring Person  inadverently and (B) during such 10
day period, and at the time of redemption, the Acquiring Person is no longer the
Beneficial Owner of 20% or more of the then outstanding shares of Common Stock.

              (b) In the case of a redemption  permitted  under  Section 23 (a),
immediately  upon the date for redemption set forth (or determined in the manner
specified in) 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 for each Right so
held. The Corporation  shall promptly give public notice of any such redemption;
provided,  however,  that the failure to give, or any defect in, any such notice
shall not affect the  validity  of such  redemption.  Within ten (10) days after
such date for  redemption  set forth in a  resolution  of the Board of Directors
ordering  the  redemption  of the  Rights,  the  Company  shall mail a notice of
redemption  to all the  holders  of the then  outstanding  Rights at their  last
addresses as they appear upon the  registry  books of the Rights Agent or, prior
to the  Distribution  Date, on the registry  books of the transfer agent for the
Common 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.  Neither the Company nor any of its  Affiliates or Associates  may
redeem, acquire or purchase for value any Rights at any time in any manner other
than that specifically set forth in this Section 23 and other than in connection
with the purchase of Common Stock prior to the Distribution Date.

              (c)  The  Company  may,  at  its  option,  discharge  all  of  its
obligations with respect to the Rights by (i) issuing a press release announcing
the manner of  redemption of the Rights in  accordance  with this  Agreement and
(ii) mailing  payment of the Redemption  Price to the registered  holders of the
Rights at their  last  addresses  as they  appear on the  registry  books of the
Rights Agent or, prior to the  Distribution  Date, on the registry  books of the
Transfer Agent of the Common Stock, and upon such action, all outstanding Rights
and Right  Certificates shall be null and void without any further action by the
Corporation.

          Section 24.  Exchange.  (a) The Board of Directors of the Company may,
at its  option,  at any time  after any  Person  becomes  an  Acquiring  Person,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include  Rights that have become void pursuant to the  provisions of Section
7(e) hereof) for shares of Common Stock,  each Right being  exchangeable for one
share of  Common  Stock,  appropriately  adjusted  to  reflect  any  transaction
specified  in Section  11(p)  occurring  after the date hereof  (such  number of
shares of Common  Stock  issuable  in exchange  for one Right 


                                       27

<PAGE>

being  referred  to  herein  as  the  "Exchange  Shares").  Notwithstanding  the
foregoing, the Board of Directors shall not be empowered to effect such exchange
at any time after any Person (other than any Exempt  Person),  together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of 50% or
more of the shares of Common Stock then outstanding.

              (b)  Immediately  upon the action of the Board of Directors of the
Company  ordering the exchange of any Rights  pursuant to subsection (a) of this
Section 24 and without any further  action and without any notice,  the right to
exercise such Rights shall  terminate and the only right  thereafter of a holder
of such  Rights  shall be to receive the  Exchange  Shares.  The  Company  shall
promptly give public notice of any such exchange;  provided,  however,  that the
failure to give,  or any defect in, such notice shall not affect the validity of
such exchange.  The Company promptly shall mail a notice of any such exchange to
all of the  holders of such Rights at their last  addresses  as they appear upon
the registry books of the Rights Agent.  Any notice that is mailed in the manner
herein  provided shall be deemed given,  whether or not the holder  receives the
notice. Each such notice of exchange will state the method by which the exchange
of the shares of Common  Stock for Rights will be effected  and, in the event of
any partial exchange, the number of Rights which will be exchanged.  Any partial
exchange  shall be effected  pro rata based on the number of Rights  (other than
Rights which have become void pursuant to the provisions of Section 7(e) hereof)
held by each holder of Rights.

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

              (d) The Company shall not be required to issue fractions of shares
of Common Stock or to distribute  certificates which evidence  fractional shares
of Common Stock. In lieu of such fractional  shares of Common Stock, the Company
shall pay to the  registered  holders of the Right  Certificates  with regard to
which such  fractional  shares of Common  Stock would  otherwise  be issuable an
amount in cash equal to the same fraction of the current market value of a whole
share of Common  Stock.  For the  purposes of this  subsection  (d), the current
market  value of a whole share of Common  Stock shall be the closing  price of a
share of Common Stock (as determined  pursuant to the second and third sentences
of Section  11(d) hereof) for the Trading Day  immediately  prior to the date of
exchange pursuant to this Section 24.

          Section 25.  Notice of Certain  Events.  (a) In case the Company shall
propose,  at any time  after  the  Distribution  Date,  (i) to pay any  dividend
payable in stock of any class to the holders of its shares of Common Stock or to
make any other  distribution to the holders of its shares of Common Stock (other
than a regular  quarterly  cash dividend) or (ii) to offer to the holders of its
shares of Common Stock  rights or warrants to  subscribe  for or to purchase any
additional  shares of Common  Stock or shares of stock of any class or any other
securities,  rights or options,  or (iii) to effect any  reclassification of its
shares  of  Common  Stock  (other  than a  reclassification  involving  only the


                                       28

<PAGE>

subdivision  of  outstanding  shares of  Common  Stock),  or (iv) to effect  any
consolidation  or merger into or with any other Person  (other than a Subsidiary
of the Company in a transaction that complies with Section 11(o) hereof),  or to
effect any sale or other transfer (or to permit one or more of its  Subsidiaries
to effect any sale or other transfer),  in one or more  transactions,  of 50% or
more of the assets or earning power of the Company and its  Subsidiaries  (taken
as a whole) to any other Person or Persons (other than the Company and/or any of
its  Subsidiaries  in one or more  transactions,  each of  which  complies  with
Section 11(o) hereof), or (v) 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 Right Certificate, in accordance with Section 26 hereof, a notice of
such proposed action that shall specify the record date for the purposes of such
stock dividend, or 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 Common 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 (i) or (ii) above at least  twenty (20) days prior to the record date for
determining  holders of the shares of Common  Stock for purposes of such action,
and in the case of any such other action, at least twenty (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 Common Stock, whichever shall be the earlier.

              (b) In case a  Triggering  Event shall  occur,  then,  in any such
case,  (i) the  Company  shall as soon as  practicable  thereafter  give to each
holder of a Right  Certificate,  in accordance  with Section 26, 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) or Section 13.

              (c) The failure to give notice  required by this Section 25 or any
defect  therein shall not affect the legality or validity of the action taken by
the Company or the vote on any such action.

          SECTION 26. Notices.  Notices or demands  authorized by this Agreement
to be  given  or  made  by the  Rights  Agent  or by  the  holder  of any  Right
Certificate to or on the Company shall be sufficiently  given or made if sent by
registered  or certified  mail and shall be deemed given upon receipt  addressed
(until  another  address  is filed in  writing  with the  Rights  Agent),  or by
facsimile with  confirmation of receipt (until another facsimile number is filed
in writing with the Rights Agent), as follows:

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 period as the Rights are not redeemable,

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 amendment or supplement  does
not adversely affect the rights or obligations of the Rights Agent under Section
18 or Section 20 of this Agreement.

          SECTION 28.  Successors.  All the  covenants  and  provisions  of this
Agreement  by or for the benefit of the  Company or the Rights  Agent shall bind

redeem,  not  redeem,  exchange  or not  exchange  the  Rights  or to amend  the
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 of  Directors  of the Company in
good  faith,  shall (x) be final,  conclusive  and binding on the  Company,  the
Rights  Agent,  the  holders  of the Rights  and all other  parties  and (y) not
subject the Board to any liability to the holders of the Rights.

shall be construed to give to any person or corporation  other than the Company,
the Rights  Agent and the  registered  holders of the Right  Certificates  (and,
prior to the  Distribution  Date,  the  shares  of  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 Right  Certificates  (and,  prior to the Distribution
Date, the registered holders of the shares of 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;
provided,  however,  that  notwithstanding  anything  in this  Agreement  to the
contrary, if any such term,  provision,  covenant or restriction is held by such
court  or  authority  to be  invalid,  void or  unenforceable  and the  Board of
Directors of the Company determines in its good faith judgment that severing the
invalid  language of this Agreement would adversely affect the purpose or effect
of this Agreement,  the right of redemption set forth in Section 23 hereof shall
be reinstated  and shall not expire until the close of business on the tenth day
following the date of such determination by the Board of Directors.

of counterparts and each of such  counterparts  shall for all purposes be deemed
to be an original,  and all such counterparts shall together  constitute but one
and the same instrument.

         funds legally available for the purpose, quarterly dividends payable in
         cash on the first day of March,  June,  September  and December in each
         year (each such date being referred to herein as a "Quarterly  Dividend
         Payment Date"), commencing on the first Quarterly Dividend Payment Date
         after the first  issuance of a share or fraction of a share of Series D
         Preferred  Stock,  in an amount per share 


                                      A-1

<PAGE>

         (rounded  to the  nearest  cent) equal to the greater of (a) $10 or (b)
         subject to the provision for  adjustment  hereinafter  set forth,  1000
         times the  aggregate per share amount of all cash  dividends,  and 1000
         times the aggregate per share amount  (payable in kind) of all non-cash
         dividends  or other  distributions,  other than a  dividend  payable in
         shares of Common Stock or a subdivision  of the  outstanding  shares of
         Common Stock (by reclassification or otherwise), declared on the Common
         Stock since the immediately  preceding  Quarterly Dividend Payment Date
         or, with respect to the first Quarterly  Dividend  Payment Date,  since
         the  first  issuance  of any share or  fraction  of a share of Series D
         Preferred Stock. In the event the Corporation shall at any time declare
         or pay any  dividend  on the Common  Stock  payable in shares of Common
         Stock, or effect a subdivision or combination or  consolidation  of the
         outstanding  shares of Common Stock (by  reclassification  or otherwise
         than by payment of a dividend in shares of Common Stock) into a greater
         or lesser number of shares of Common Stock,  then in each such case the
         amount to which  holders  of shares of Series D  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 D Preferred  Stock as provided in  paragraph  (A) of this
         Section immediately after it declares a dividend or distribution on the
         Common Stock (other than a dividend payable in shares of Common Stock);
         provided that, in the event no dividend or distribution shall have been
         declared on the Common  Stock during the period  between any  Quarterly
         Dividend  Payment  Date  and the  next  subsequent  Quarterly  Dividend
         Payment  Date,  a dividend  of $10 per share on the Series D  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 D  Preferred  Stock  from the  Quarterly
         Dividend  Payment Date next preceding the date of issue of such shares,
         unless the date of issue of such shares is prior to the record date for
         the first Quarterly  Dividend  Payment Date, in which case dividends on
         such  shares  shall  begin  to  accrue  from  the date of issue of such
         shares,  or unless the date of issue is a  Quarterly  Dividend  Payment
         Date or is a date  after  the  record  date  for the  determination  of
         holders of shares of Series D  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 D 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 D  Preferred  Stock
         entitled  to receive  payment of a dividend  or  distribution  declared
         thereon,  which record date shall be not more than 60 days prior to the
         date fixed for the payment thereof.

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

                  (A) Subject to the provision for  adjustment  hereinafter  set
         forth,  each share of Series D Preferred Stock shall entitle the holder
         thereof  to  1000  votes  on all  matters  submitted  to a vote  of the
         stockholders of the Corporation.  In the event the Corporation shall at
         any time  declare or pay any  dividend on the Common  Stock  payable in
         shares of Common  Stock,  or effect a  subdivision  or  combination  or
         consolidation   of  the   outstanding   shares  of  Common   Stock  (by
         reclassification  or otherwise  than by payment of a dividend in shares
         of Common  Stock)  into a greater or lesser  number of shares of Common
         Stock,  then in each such  case the  number of votes per share to which
         holders of shares of Series D 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,  in  any  other
         Certificate of Designations creating a series of Preferred Stock or any
         similar  stock,  or by law, the holders of shares of Series D Preferred
         Stock and the holders of shares of Common  Stock and any other  capital
         stock of the  Corporation  having  general  voting  rights  shall  vote
         together  as  one  class  on  all  matters   submitted  to  a  vote  of
         stockholders of the Corporation.

                  (C) Except as set forth  herein,  or as otherwise  provided by
         law,  holders of Series D 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 D  Preferred  Stock as provided in
         Section 2 are in arrears,  thereafter  and until all accrued and unpaid
         dividends  and  distributions,  whether or not  declared,  on shares of
         Series D Preferred Stock  outstanding shall have been paid in full, the
         Corporation shall not: (i) declare or pay dividends,  or make any other
         distributions,  on any  shares of stock  ranking  junior  (either as to
         dividends or upon liquidation, dissolution or winding up) to the Series
         D Preferred Stock;

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

                  (iii)   redeem  or   purchase   or   otherwise   acquire   for
         consideration  shares  of  any  stock  ranking  junior  (either  as  to
         dividends or upon liquidation, dissolution or winding up) to the Series
         D  Preferred  Stock,  provided  that  the  Corporation  may at any time
         redeem,  


                                      A-3

<PAGE>

         purchase  or  otherwise  acquire  shares  of any such  junior  stock in
         exchange  for  shares of any stock of the  Corporation  ranking  junior
         (either as to dividends or upon dissolution, liquidation or winding up)
         to the Series D Preferred Stock; or

                  (iv) redeem or purchase or otherwise acquire for consideration
         any shares of Series D Preferred  Stock, or any shares of stock ranking
         on a parity with the Series D  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  Dnd  classes,  shall  determine  in good faith will
         result in fair and equitable  treatment among the respective  series or
         classes.

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

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

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


                                       A-4

<PAGE>

the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

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

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

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

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