Item 5.           Other Events

         As of  December  30,1997,  the  Board of  Directors  of PSC  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  to  shareholders  of record at the close of
business on  December  30, 1997 (the  "Record  Date") and for each Common  Share
issued (including shares distributed from Treasury by the Company thereafter and
prior to the  Distribution  Date (as defined  below)).  Each Right  entitles the
registered  holder,  subject to the terms of the Rights  Agreement  (as  defined
below), to purchase from the Company one one-thousandth of a share (a "Unit") of
Series B Preferred Stock, par value $.01 per share (the "Preferred  Stock") at a
purchase price of $45.00 per Unit (the "Purchase Price"), subject to adjustment.
The Purchase  Price is payable in cash or by certified or bank check  payable to
the order of the  Company or by wire  transfer  to the  account  of the  Company
(provided  a notice of such wire  transfer is given by the holder of the related
Right to the  Rights  Agent).  The  description  and terms of the Rights are set
forth in a Rights  Agreement  (the "Rights  Agreement")  between the Company and
ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the "Rights Agent").

     Until the  Distribution  Date (or earlier  redemption  or expiration of the
Rights),  which is defined  below,  the Rights will be evidenced with respect to
any of the Common Share certificates  outstanding prior to the Distribution Date
by such Common Share  certificates  and no separate Right  Certificates  will be
distributed.  The Rights Agreement provides that until the Distribution Date (or
earlier  redemption  or  expiration  of the  Rights),  (i)  the  Rights  will be
transferred  with and only  with  the  Common  Shares,  (ii)  new  Common  Share
certificates  issued after the Record Date,  upon  transfer,  replacement or new
issuance  of Common  Shares  will be deemed to be issued  with  Rights  and will
contain a notation  incorporating  the Rights Agreement by reference,  and (iii)
the surrender for transfer of any certificates for Common Shares, outstanding as
of the Record  Date,  even  without  such  notation or a copy of this 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.  From and after the  Distribution  Date, such separate Right
Certificates alone will evidence the Rights.

         As defined in the Rights Agreement,  the "Distribution  Date" means the
earlier  to  occur  of (i) 10  business  days  following  the  date of a  public
announcement (the date of such announcement being the "Shares Acquisition Date")
that a person,  together with persons  affiliated  or associated  with it (other
than the Company,  any subsidiary of the Company,  any employee  benefit plan of
the Company or such subsidiary) (an "Acquiring Person"), has acquired beneficial
ownership of 20% or more of the then outstanding Common Shares of the Company or

<PAGE>

(ii) 10 business  days (or such later date as may be determined by action of the
Board of  Directors  prior to such  time as any  person  or group of  affiliated
persons becomes an Acquiring  Person)  following the earlier of the commencement
of, or the first public  announcement of the intent to commence,  a tender offer
or exchange  offer by a person other than the Company if, upon  consummation  of
the offer, such person,  together with persons affiliated or associated with it,
would be the beneficial owner of 20% or more of the outstanding Common Shares.

         The Rights are not exercisable until the Distribution  Date. The Rights
will expire at the close of business on December 30, 2007 (the "Final Expiration
Date"), unless earlier redeemed or exchanged by the Company as described below.

         The Purchase Price payable,  and the number of Units of Preferred Stock
issuable,  upon  exercise of the Rights are subject to  adjustment  from time to
time  to  prevent  dilution  (i) in the  event  of a  stock  dividend  on,  or a
subdivision,  combination or reclassification of, the Preferred Stock, (ii) upon
the grant to holders of the  Preferred  Stock of certain  rights or  warrants to
subscribe for or purchase Preferred Stock at a price, or securities  convertible
into Preferred Stock with a conversion  price, less than the then current market
price of the Preferred  Stock or (iii) upon the  distribution  to holders of the
Preferred Stock of evidences of indebtedness,  cash or assets (excluding regular
quarterly  cash  dividends  or  dividends  payable  in  Preferred  Stock)  or of
subscription  rights or  warrants  (other than those  referred  to above).  With
certain  exceptions,  no adjustment in the Purchase Price will be required until
cumulative  adjustments  require an  adjustment  of at least 1% in the  Purchase
Price. The Company is not required to issue fractional Units. In lieu thereof an
adjustment  in cash may be made based on the market value of a Unit of Preferred
Stock on the last trading day prior to the date of exercise.

         The number of outstanding  Rights are also subject to adjustment in the
event of a stock  split of the Common  Shares or a stock  dividend on the Common
Shares, payable in Common Shares or subdivisions, consolidations or combinations
of the Common  Shares  occurring,  in any such case,  prior to the  Distribution
Date.

         In the  event  that a  person,  together  with  persons  affiliated  or
associated with it, becomes an Acquiring Person,  each holder of a Right, except
as provided  below,  will  thereafter  have the right to receive,  upon exercise
thereof, Units of Preferred Stock having a value equal to two times the exercise
price of the Right.  The exercise price is the Purchase Price  multiplied by the
number of Units of Preferred  Stock  issuable  upon exercise of a Right prior to
the event set forth in the preceding  sentence.  Notwithstanding  the foregoing,
following the  occurrence  of the event set forth in the first  sentence in this
paragraph, all Rights that are, or (under certain circumstances set forth in the
Rights  Agreement)  were,  beneficially  owned by any  Acquiring  Person  (or by
certain related parties and transferees) will be null and void.
<PAGE>

         In the event  that (i) the  Company  is  acquired  in a merger or other
business  combination  transaction  in which the  Company  is not the  surviving
corporation,  or (ii) fifty  percent  (50%) or more of the  Company's  assets or
earning power is sold or transferred,  each holder of a Right (other than Rights
that  theretofore  become  null and void as  described  in the second  preceding
paragraph)  shall thereafter have the right to receive,  upon exercise  thereof,
common  stock of the  acquiring  company  having a value  equal to two times the
exercise price of the Right.

         At any time  until the close of  business  on the  tenth  business  day
following the Shares Acquisition Date, 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"),  payable at the election of the Board of Directors, in cash
or Company Common Shares.  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 the  action of the Board of
Directors  of the  Company  ordering  redemption  of the  Rights,  the  right to
exercise the Rights will  terminate  and the only right of the holders of Rights
will be to receive the Redemption Price.

         At any time after a person or group of affiliated or associated persons
becomes an Acquiring  Person,  the Board of  Directors  of the  Company,  at its
option, may exchange each Right (other than Rights owned by such person or group
which have  become  void),  in whole or in part,  for Common  Shares or Units of
Preferred Stock at an exchange ratio of on Common Share or one Unit of Preferred
Stock per Right (subject to adjustment).

         Any of the  provisions of the Rights  Agreement may be amended  without
the  approval of the holders of Company  Common  Shares at any time prior to the
Distribution  Date.  After the  Distribution  Date, the provisions of the Rights
Agreement   may  be  amended  in  order  to  cure  any   ambiguity,   defect  or
inconsistency,  to make changes which do not  adversely  affect the interests of
holders of Rights  (excluding  the  interests of any  Acquiring  Person),  or to
shorten  or  lengthen  any time  period  under the Rights  Agreement;  provided,
however,  that no amendment to adjust the time period governing redemption shall
be made at such time as the Rights are not redeemable.

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive  dividends.  While the distribution of the Rights will not
be taxable to shareholders or to the Company, shareholders may, depending on the
circumstances,  recognize  taxable  income in the event that the  Rights  become
exercisable for Units of Preferred Stock.
<PAGE>

         The Units of Preferred  Stock that may be acquired upon exercise of the
Rights will be  nonredeemable  and will be  subordinate  to any other  shares of
preferred  stock  that have been or may be issued by the  Company.  Each Unit of
Preferred Stock will receive ratably any dividend declared on the Company Common
Shares. In the event of liquidation,  the holder of each Unit of Preferred Stock
will receive a preferred  liquidation  payment equal to the greater of $1.00 per
Unit or the per share  amount paid in respect of a share of the  Company  Common
Shares.  Each Unit of Preferred  Stock will have one vote,  voting together with
the Company Common Shares.  In the event of any merger,  consolidation  or other
transaction in which Company Common Shares are exchanged, each Unit of Preferred
Stock will be entitled  to receive the per share  amount paid in respect of each
share of Company Common Shares.  The rights of holders of the Preferred Stock to
dividends,   liquidation   and   voting,   and  in  the  event  of  mergers  and
consolidations, are protected by customary antidilution provisions.

         Because of the nature of the Preferred Stock dividend,  liquidation and
voting  rights,  the economic  value of one Unit of Preferred  Stock that may be
acquired upon the exercise of each Right is expected to approximate the economic
value of one share of Company Common Shares.

         The Rights  will not prevent a takeover of the  Company.  However,  the
Rights may have certain anti-takeover effects. The Rights will cause substantial
dilution to a person or group that  attempts to acquire the Company on terms not
approved  by the  Company's  Board of  Directors,  except  pursuant  to an offer
conditioned on a substantial  number of Rights being acquired.  In general,  the
Rights  should  not  interfere  with any  merger or other  business  combination
approved  by the Board of  Directors  since the  Rights may be  redeemed  by the
Company  at the  Redemption  Price  prior to the time that a person or group has
acquired beneficial ownership of 20% or more of the Common Shares.

         Attached hereto as Exhibit 4.1 and incorporated herein by reference are
a copy of the Rights  Agreement,  dated as of  December  30,  1997,  between the
Company  and  ChaseMellon  Shareholder  Services,   L.L.C.,  as  Rights  Argent,
specifying  the terms of the  Rights,  and the  exhibits  thereto,  as  follows:
Exhibit A - Form of Right Certificate; Exhibit B - Summary of Rights to Purchase
Preferred  Stock;  and Exhibit C - Form of Certificate of Amendment  designating
the  relative  rights  preferences  and  limitations  of the Series B  Preferred
Shares. The foregoing  description of the Rights does not purport to be complete
and is qualified in its  entirety by reference to the Rights  Agreement  and the
exhibits thereto.

                                RIGHTS AGREEMENT


         Agreement, dated as of  December 30, 1997, between PSC Inc., a New York
corporation (the "Company") and ChaseMellon Shareholder Services, L.L.C. (the 
"Rights Agent")

The Board of Directors of the Company has  authorized and declared a dividend of
one  Preferred  Share  purchase  right (a  "Right")  for each  Common  Share (as
hereinafter  defined)  of the  Company  outstanding  on the close of business on
December  30, 1997 (the "Record  Date"),  each Right  representing  the right to
purchase  one Unit (as defined  below) of Series B  Preferred  Stock (as defined
below),  upon the terms and subject to the conditions  herein set forth, and has
further  authorized  and directed the issuance of one Right with respect to each
Common  Share that shall  become  outstanding  between  the Record  Date and the
earliest of the  Distribution  Date, the Redemption Date or the Final Expiration
Date (as such  terms are  hereinafter  defined)  and as  otherwise  provided  in
Section 3 of this Agreement.

Accordingly,  in consideration of the premises and the mutual  agreements herein
set forth, the parties hereby agree as follows:

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

(a)  "Acquiring  Person"  shall  mean any  Person  (as such term is  hereinafter
defined) who or which,  together with all  Affiliates  and  Associates  (as such
terms are hereinafter  defined) of such Person,  after the date hereof, shall be
the Beneficial Owner (as such term is hereinafter defined) of 20% or more of the
Common  Shares of the  Company  then  outstanding,  but shall  not  include  the
Company,  any subsidiary  (as such term is hereinafter  defined) of the Company,
any employee  benefit plan of the Company or any  Subsidiary of the Company,  or
any entity  holding Common Shares for or pursuant to the terms of any such plan.
Notwithstanding  the foregoing,  no Person shall become an "Acquiring Person" as
the result of an acquisition of Common Shares by the Company which,  by reducing
the number of shares outstanding,  increases the proportionate  number of shares
beneficially owned by such Person together with all Affiliates and Associates of
such Person to 20% or more of the Common Shares of the Company then outstanding;
provided,  however, that if a Person shall become the Beneficial Owner of 20% or
more of the Common  Shares of the Company  then  outstanding  by reason of share
purchases by the Company and shall,  after such share  purchases by the Company,
become the Beneficial Owner of any additional Common Shares of the Company, then
such Person shall be deemed to 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

<PAGE>

to  the   foregoing   provisions  of  this   paragraph   (a),  has  become  such
inadvertently,  and such Person  divests as promptly as practicable a sufficient
number of Common  Shares so that such  Person  would no longer be an  "Acquiring
Person," as defined pursuant to the foregoing  provisions of this paragraph (a),
then such Person shall not be deemed to be an "Acquiring Person" for any purpose
of this Agreement. For purposes of determining whether a Person is an "Acquiring
Person," a Person engaged in business as an underwriter of securities  shall not
be deemed to be an  Acquiring  Person as a result of such  Person  becoming  the
"Beneficial   Owner"  of  any   securities   acquired   through  such   Person's
participation in good faith in a firm commitment underwriting unless such Person
is the  "Beneficial  Owner" of such securities upon the expiration of forty (40)
days after the date of such acquisition.  The  determination  whether any Person
acted in "good faith" shall be conclusively determined by the Board of Directors
of the Company.

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

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

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

         (ii) which such Person or any of such Person's Affiliates or Associates
has (A) the right to acquire  (whether such right is exercisable  immediately or
only after the  passage  of time)  pursuant  to any  agreement,  arrangement  or
understanding (other than customary agreements with and between underwriters and
selling  group  members  with  respect  to  a  bona  fide  public   offering  of
securities),  or upon the exercise of conversion rights, exchange rights, rights
(other than these Rights), warrants or options, or otherwise; provided, however,
that a Person shall not be deemed the  Beneficial  Owner of, or to  beneficially
own,  securities  tendered  pursuant to a tender or exchange offer made by or on
behalf of such Person or any of such Person's  Affiliates  or  Associates  until
such tendered securities are accepted for purchase or exchange; or (B) the right
to vote  pursuant to any  agreement,  arrangement  or  understanding;  provided,
however,  that a Person  shall  not be  deemed  the  Beneficial  Owner of, or to
beneficially  own,  any security  pursuant to this clause (b) if the  agreement,
arrangement  or  understanding  to vote such  security (1) arises  solely from a
revocable proxy or consent given to such Person in response to a public proxy or
consent  solicitation  made pursuant to, and in accordance  with, the applicable
rules and  regulations  promulgated  under the  Exchange Act and (2) is not also
then  reportable  on Schedule 13D under the Exchange Act (or any  comparable  or
successor report); or
<PAGE>

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

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

(d) "Business Day" shall mean any day other than a Saturday,  a Sunday, or a day
on which  banking  institutions  in the  State of New  York  are  authorized  or
obligated by law or executive order to close.

(e) The "Close of  business"  on any given  date shall mean 5:00 P.M.,  New York
City, New York time, on such date; provided, however, that if such date is not a
Business Day it shall mean 5:00 P.M.,  New York City, New York time, on the next
succeeding Business Day.

(f) "Common  Shares"  when used with  reference  to the  Company  shall mean the
shares of common  stock,  par value  $.01 per  share,  of the  Company.  "Common
Shares" when used with reference to any Person other than the Company shall mean
the capital stock (or equity  interest)  with the greatest  voting power of such
other  Person or, if such other  Person is a  Subsidiary  of another  Person the
Person or Persons which ultimately control such first-mentioned Person.

(g) "Depositary Agent" shall have the meaning set forth in Section 7(c).

(h)  "Distribution  Date" shall mean the earlier of (i) the close of business on
the tenth business day after the Shares Acquisition Date, as hereinafter defined
(or, if the tenth business day after the Shares  Acquisition  Date occurs before
the Record Date, the close of business on the Record Date), or (ii) the close of
business on the tenth  business day (or such later day as may be  determined  by
the  Board of  Directors)  after the date of the  commencement  of, or the first
public  announcement  of the intent to commence (as determined  pursuant to Rule
14d-2(a) of the General Rules and  Regulations  under the Exchange Act in effect
on the date of this Agreement),  a tender or exchange offer by any Person (other
than the  Company,  any  Subsidiary  of the  Company,  or any  Person  or entity
organized, appointed or established by or for the Company for or pursuant to the
terms of any such Plan), if upon consummation  thereof,  such Person would be an
Acquiring  Person  (including  any such  date  which  is after  the date of this
Agreement and prior to the issuance of the Rights).

(i)  "Equivalent  Preferred  Stock"  shall have the meaning set forth in Section
11(b) hereof.
<PAGE>

(j)  "Final  Expiration  Date"  shall  have the  meaning  set forth in Section 7
hereof.

per share, of the Company having the voting powers, designation, preferences and
relative  participating,  optional or other special  rights and  qualifications,
limitations and restrictions described in the Certificate of Amendment set forth
as Exhibit C hereto.

(m) "Redemption Date" shall have the meaning set forth in Section 7 hereof.

Company or an Acquiring Person that an Acquiring Person has become such.

(o)  "Subsidiary"  of any Person shall mean any  corporation  or other entity of
which a majority of the voting power of the voting  equity  securities or equity
interest is owned, directly or indirectly, by such Person.

Section 2.  Appointment of Rights Agent.  The Company hereby appoints the Rights
Agent  to act as  agent  for the  Company  in  accordance  with  the  terms  and
conditions  hereof,  and the Rights Agent hereby accepts such  appointment.  The
Company  may from  time to time  appoint  such  co-Rights  Agents as it may deem
necessary or desirable.

Section 3. Issue of Right  Certificates.  (a) Until the  Distribution  Date, the
Rights will be evidenced  (subject to the  provisions of Section 3(b) hereof) by
the  certificates  for  Common  Shares  registered  in the names of the  holders
thereof (which  certificates shall also be deemed to be Right  Certificates) and
not by separate Right Certificates,  and the Rights will be transferred with and
only with the transfer of the underlying  Common Shares (including a transfer to
the Company).  As soon as practicable  after the Distribution  Date, the Company
will prepare and execute,  the Rights  Agent will  countersign,  and the Company
will send or cause to be sent (and the Rights Agent will, if requested, send) by
first-class,  insured,  postage  prepaid  mail,  to each record holder of Common
Shares as of the close of business on the  Distribution  Date, at the address of
such  holder  shown on the  records  of the  Company,  a Right  Certificate,  in
substantially the form of Exhibit A hereto (a "Right  Certificate"),  evidencing
one Right for each Common Share so held. As of and after the Distribution  Date,
the Rights will be evidenced solely by such Right Certificates.
<PAGE>

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

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

"This  certificate  also  evidences  and entitles  the holder  hereof to certain
rights as set  forth in a Rights  Agreement  between  PSC Inc.  and  ChaseMellon
Shareholder  Services,  L.L.C.  dated  as of  December  30,  1997  (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 PSC Inc. Under
certain circumstances, as set forth in the Rights Agreement, such rights will be
evidenced  by  separate  certificates  and will no longer be  evidenced  by this
certificate.  PSC Inc. will mail to the holder of this certificate a copy of the
Rights  Agreement  without charge after receipt of a written  request  therefor.
Under certain circumstances, as set forth in the Rights Agreement, Rights issued
to any  Person  who  becomes  an  Acquiring  Person  (as  defined  in the Rights
Agreement) may become null and void."

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

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

Section 5.  Countersignature  and Registration.  The Right Certificates shall be
executed  on behalf of the  Company  by its  Chairman  of the  Board,  its Chief
Executive Officer, its President,  any of its Vice Presidents,  or its Treasurer
either  manually  or by  facsimile  signature,  shall have  affixed  thereto the
Company's seal or a facsimile thereof, and shall be attested by the Secretary or
an  Assistant  Secretary  of  the  Company,  either  manually  or  by  facsimile
signature.  The Right  Certificates  shall be countersigned by the Rights Agent,
either  manually  or by  facsimile  signature,  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 he countersigned by the
Rights  Agent and issued and  delivered  by the Company  with the same force and
effect as though the person who signed such Right Certificates had not ceased to
be such  officer  of the  Company;  and any Right  Certificate  may be signed on
behalf of the Company by any person who, at the actual date of the  execution of
such Right  Certificate,  shall be a proper  officer of the Company to sign such
Right  Certificate,  although  at the  date  of the  execution  of  this  Rights
Agreement any such person was not such an officer.

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

Section 6. Transfer,  Split Up, Combination and Exchange of Right  Certificates;
Mutilated,  Destroyed,  Lost  or  Stolen  Right  Certificates.  Subject  to  the
provisions of Section 14 hereof,  at any time after the close of business on the
Distribution  Date,  and at or prior to the close of  business on the earlier of
the Redemption Date or the Final Expiration Date, any Right Certificate or Right
Certificates (other than Right Certificates representing Rights that have become
void pursuant to Section  11(a)(ii) hereof or that have been exchanged  pursuant
to Section 24 hereof) may be  transferred,  split up,  combined or exchanged for
another Right Certificate or Right Certificates, entitling the registered holder
to  purchase  a  like  number  of  Units  as  the  Right  Certificate  or  Right
Certificates  surrendered then entitled such holder to purchase.  Any registered
holder desiring to transfer, split up, combine or exchange any Right Certificate
or Right Certificates shall make such request in writing delivered to the Rights
Agent,  and shall  surrender the Right  Certificate or Right  Certificates to be

<PAGE>

transferred,  split up,  combined or  exchanged at the  principal  office of the
Rights  Agent.  Neither the Rights  Agent nor the Company  shall be obligated to
take any action whatsoever with respect to the transfer,  split up,  combination
or exchange of any such  surrendered  Right  Certificate  unless the  registered
holder  thereof  shall have  completed  and signed  the form of  assignment  and
related certificate 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  countersign  and
deliver  to  the  person   entitled   thereto  a  Right   Certificate  or  Right
Certificates,  as the case may be, as so  requested.  The  Company  may  require
payment of a sum sufficient to cover any tax or governmental  charge that may be
imposed in connection  with any transfer,  split up,  combination or exchange of
Right Certificates.

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

Section 7. Exercise of Rights;  Purchase Price;  Expiration Date of Rights.  (a)
The registered holder of any Right Certificate may exercise the Rights evidenced
thereby  (except as otherwise  provided  herein) in whole or in part at any time
after the Distribution  Date upon surrender of the Right  Certificate,  with the
form of election to purchase on the reverse side thereof duly  executed,  to the
Rights Agent at the principal office of the Rights Agent,  together with payment
of the Purchase Price for each Unit as to which the Rights are exercised,  at or
prior to the  earliest of (i) the close of  business  on December  30, 2007 (the
"Final  Expiration  Date"),  (ii) the time at which the Rights are  redeemed  as
provided  in Section 23 hereof  (the  "Redemption  Date"),  or (iii) the time at
which such Rights are exchanged as provided in Section 24 hereof.

(b) The Purchase Price for each Unit of Preferred Stock pursuant to the exercise
of a Right shall  initially be $45 shall be subject to  adjustment  from time to
time as  provided  in  Sections  11 and 13 hereof and shall be payable in lawful
money of the United States of America in accordance with paragraph (d) below.

(c) As promptly as  practicable  following the  occurrence  of the  Distribution
Date,  the Company shall deposit with a corporation  in good standing  organized
under the laws of the United States or any State of the United States,  which is
authorized under such laws to exercise  corporate trust or stock transfer powers
and is subject to supervision or examination by federal or state  authority (the
"Depositary  Agent"),  certificates  representing  the shares of Preferred Stock
that may be acquired upon exercise of the Rights and shall cause such Depositary

<PAGE>

Agent to enter into an agreement  pursuant to which the  Depositary  Agent shall
issue  receipts  representing  interests  in the  shares of  Preferred  Stock so
deposited.  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 each Right to be  exercised  and an amount equal to any
applicable  transfer  tax  required  to be paid  by the  holder  of  such  Right
Certificate in accordance  with Section 9 hereof by certified  check,  cashier's
check or money order payable to the order of the Company, the Rights Agent shall
thereupon promptly (i) requisition from the Depositary Agent (or make available,
if the Rights Agent is the Depositary  Agent) depositary  receipts  representing
such Units of  Preferred  Stock as are to be  purchased  and the Company  hereby
irrevocably  authorizes its  Depositary  Agent to comply with all such requests,
(ii) when  appropriate,  requisition  from the  Company the amount of cash to be
paid in lieu of issuance of  fractional  shares in  accordance  with  Section 14
hereof,  (iii) after receipt of such depositary  receipts,  cause the same to be
delivered  to or  upon  the  order  of  the  registered  holder  of  such  Right
Certificate,  registered  in such  name or  names as may be  designated  by such
holder and (iv) when  appropriate,  after receipt,  deliver such cash to or upon
the order of the registered holder of such Right Certificate.

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

(e) The Company  covenants and agrees that it will cause to be reserved and kept
available out of its  authorized  and unissued  Preferred  Stock,  the number of
shares of Preferred Stock that will be sufficient to permit the exercise in full
of all outstanding Rights in accordance with this Section 7.

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

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

Section  9.  Reservation  and  Availability  of  Preferred  Stock.  The  Company
covenants  and agrees that it will take all such action as may be  necessary  to
ensure that all Preferred  Stock delivered upon exercise of Rights shall, at the
time of  delivery  of the  certificates  for such  Preferred  Stock  (subject to
payment of the Purchase  Price),  be duly and validly  authorized and issued and
fully paid and nonassessable shares.

The Company  further  covenants and agrees that it will pay when due and payable
any and all federal and state transfer taxes and charges which may be payable in
respect  of the  issuance  or  delivery  of  the  Right  Certificates  or of any
Preferred Stock upon the exercise of Rights. The Company shall not, however,  be
required to pay any transfer tax which may be payable in respect of any transfer
or delivery of Right  Certificates  to a person  other than,  or the issuance or
delivery of  certificates  or depositary  receipts for the Preferred  Stock in a
name  other  than  that of,  the  registered  holder  of the  Right  Certificate
evidencing  Rights  surrendered  for  exercise  or to  issue or to  deliver  any
certificates for Preferred Stock or depositary receipts upon the exercise of any
Rights  until any such tax shall  have been paid (any such tax being  payable by
the holder of such Right  Certificate  at the time of surrender) or until it has
been established to the Company's  reasonable  satisfaction  that no such tax is
due.

The  Company  shall use its best  efforts  to (i) file,  as soon as  practicable
following  the Shares  Acquisition  Date,  a  registration  statement  under the
Securities Act of 1933 with respect to the securities  purchasable upon exercise
of the Rights on an appropriate form, (ii) cause such registration  statement to
become effective as soon as practicable after such filing,  and (iii) cause such
registration  statement  to remain  effective  (with a  prospectus  at all times
meeting the  requirements of the Act and the rules and  regulations  thereunder)
until the earlier of the Expiration  Date or the date as of which the rights are
no  longer  exercisable.  The  Company  will  also  take  such  action as may be
appropriate under the blue sky laws of the various states.

Section  10.  Preferred  Stock  Record  Date.  Each  person  in  whose  name any
depositary  certificate  or certificate  for Preferred  Stock is issued upon the
exercise of Rights shall for all purposes be deemed to have become the holder of
record  of the  Units  of  Preferred  Stock  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 Stock transfer books of
the Company are  closed,  such person  shall be deemed to have become the record
holder  of such  shares  on,  and  such  certificate  shall be  dated,  the next
succeeding  Business  Day on which the  Preferred  Stock  transfer  books of the
Company are open.  Prior to the exercise of the Rights  evidenced  thereby,  the
holder of a Right Certificate shall not be entitled to any rights of a holder of
the Units of Preferred  Stock or other  securities 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.
<PAGE>

Section 11. Adjustment of Purchase Price, Number and Kind of Shares or Number of
Rights.  The Purchase  Price,  the number of Units of  Preferred  Stock or other
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  Stock  payable in shares of
Preferred Stock, (B) subdivide the outstanding  Preferred Stock, (C) combine the
outstanding  Preferred  Stock into a smaller number of shares of Preferred Stock
or (D)  issue any  shares  of its  capital  stock in a  reclassification  of the
Preferred  Stock  (including  any such  reclassification  in  connection  with a
consolidation  or merger in which the  Company is the  continuing  or  surviving
corporation),  except as otherwise  provided in this Section 11(a), 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 Preferred  Stock or capital stock,  as the case may
be, 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 Preferred  Stock or shares of capital stock which,
if such Right had been  exercised  immediately  prior to such date and at a time
when the Preferred  Stock transfer  books of the Company were open,  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 shares of Preferred  Stock of
the Company issuable upon exercise of one Right.

(ii) Subject to Section 24 of this Agreement,  in the event any Person, alone or
together with its Affiliates and Associates,  shall become an Acquiring  Person,
each holder of a Right shall  thereafter have a right to receive,  upon exercise
thereof at a price equal to the then current  Purchase  Price  multiplied by the
number of Units of  Preferred  Stock for which a Right is then  exercisable,  in
accordance with the terms of this  Agreement,  such number of Units of Preferred
Stock of the Company as shall equal the result  obtained by (x)  multiplying the
then current  Purchase Price by the number of Units of Preferred Stock for which
a Right is then  exercisable  and  dividing  that product by (y) 50% of the then
current  market  price of the  Company's  Units of Preferred  Stock  (determined
pursuant  to  Section  11(d)  hereof)  on the date  when such  Person  became an
Acquiring  Person. In the event that any Person shall become an Acquiring Person
and the Rights shall then be outstanding,  the Company shall not take any action
which would  eliminate or diminish  the benefits  intended to be afforded by the
Rights.
<PAGE>

From and after the time when a Person  becomes an Acquiring  Person,  any Rights
that are or were acquired or beneficially owned by such Acquiring Person (or any
Associate or Affiliate of such Acquiring Person) shall be void and any holder of
such Rights  shall  thereafter  have no right to exercise  such Rights under any
provision of this Agreement.  No Right  Certificate  shall be issued pursuant to
Section 3 that represents Rights beneficially owned by an Acquiring Person whose
Rights  would be void  pursuant to the  preceding  sentence or any  Associate or
Affiliate  thereof;  no Right  Certificate  shall be issued at any time upon the
transfer  of any  Rights  to an  Acquiring  Person  whose  Rights  would be void
pursuant to the preceding  sentence or any Associate or Affiliate  thereof or to
any nominee of such  Acquiring  Person,  Associate or  Affiliate;  and any Right
Certificate  delivered to the Rights  Agent for transfer to an Acquiring  Person
whose  Rights  would  be  void  pursuant  to the  preceding  sentence  shall  be
cancelled.

(iii) In the event that there shall not be sufficient Preferred Stock issued but
not outstanding or authorized but unissued to permit the exercise in full of the
Rights in accordance  with the foregoing  subparagraph  (ii),  the Company shall
take all such action as may be necessary to authorize additional Preferred Stock
for issuance upon exercise of the Rights.

(b) In case the  Company  shall fix a record  date for the  issuance  of rights,
options or warrants  to all holders of  Preferred  Stock  entitling  them (for a
period expiring within 45 calendar days after such record date) to subscribe for
or purchase shares of Preferred Stock (or shares having  substantially  the same
rights,  privileges and  preferences as shares of Preferred  Stock  ("Equivalent
Preferred Stock")) or securities convertible into Preferred Stock at a price per
share of Preferred  Stock or Equivalent  Preferred Stock (or having a conversion
price per share,  if a security  convertible  into Preferred Stock or Equivalent
Preferred  Stock)  less  than the then  current  per share  market  price of the
Preferred  Stock (as defined in Section 11(d)) on such record date, the Purchase
Price to be in effect after such record date shall be determined by  multiplying
the  Purchase  Price  in  effect  immediately  prior  to such  record  date by a
fraction,  the  numerator  of which  shall be the number of shares of  Preferred
Stock  outstanding  on such record  date plus the number of shares of  Preferred
Stock  which  the  aggregate  offering  price of the  total  number of shares of
Preferred  Stock or  Equivalent  Preferred  Stock so to be offered  (and/or  the
aggregate  initial  conversion  price  of the  convertible  securities  so to be
offered)  would  purchase at such current  market price and the  denominator  of
which  shall be the  number of  shares  of  Preferred  Stock  and/or  Equivalent
Preferred  Stock  outstanding  on such record date plus the number of additional
shares of Preferred  Stock and/or  Equivalent  Preferred Stock to be offered for
subscription  or purchase  (or into which the  convertible  securities  so to be
offered are initially  convertible);  provided,  however, that in no event shall
the  consideration  to be paid upon the  exercise  of one Right be less than the
aggregate par value of the shares of capital stock of the Company  issuable upon
exercise  of one  Right.  In  case  such  subscription  price  may be  paid in a
consideration part or all of which shall be in a form other than cash, the value
of such  consideration  shall be as  determined  in good  faith by the  Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights  Agent and shall be binding  upon the Rights Agent and the
holders  of the  Rights.  Shares  of  Preferred  Stock  owned by or held for the
account of the Company  shall not be deemed  outstanding  for the purpose of any
such  computation.  Such adjustment shall be made  successively  whenever such a
record date is fixed; and in the event that such rights, options or warrants are
not so issued,  the Purchase  Price shall be adjusted to be the  Purchase  Price
which would then be in effect if such record date had not been fixed.
<PAGE>

(c) In case the Company shall fix a record date for the making of a distribution
to all holders of the Preferred Stock (including any such  distribution  made in
connection with a consolidation or merger in which the Company is the continuing
or surviving  corporation)  of evidences of indebtedness or assets (other than a
regular  quarterly  cash  dividend or a dividend  payable in shares of Preferred
Stock) or  subscription  rights or  warrants  (excluding  those  referred  to in
Section 11(b) hereof), the Purchase Price to be in effect after such record date
shall be  determined by  multiplying  the Purchase  Price in effect  immediately
prior to such  record date by a fraction,  the  numerator  of which shall be the
then current per share market price as  determined  pursuant to Section 11(d) of
the shares of Preferred  Stock 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  upon the Rights  Agent and the  holders of the  Rights) of the
portion of the assets or evidences of  indebtedness  so to be  distributed or of
such subscription  rights or warrants applicable to one share of Preferred Stock
and the  denominator  of which shall be such  current per share  market price as
determined pursuant to Section 11(d) of the Preferred Stock; 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 to be issued upon exercise of one Right.  Such adjustments shall be made
successively  whenever  such a record date is fixed;  and in the event that such
distribution  is not so made,  the Purchase  Price shall again be adjusted to be
the  Purchase  Price  which  would then be in effect if such record date had not
been fixed.

(d) (i) For the purpose of any  computation  hereunder,  the  "current per share
market price" of the Common Shares on any date shall be deemed to be the average
of the  daily  closing  prices  per  share  of  such  Common  Shares  for the 30
consecutive Trading Days (as such term is hereinafter defined) immediately prior
to such date;  provided,  however,  that in the event that the current per share
market price of the Common  Shares is determined  during a period  following the
announcement  by  the  issuer  of  such  Common  Shares  of  (A) a  dividend  or
distribution  on such Common  Shares  payable in shares of such Common Shares or
securities convertible into such shares, or (B) any subdivision,  combination or
reclassification of such Common Shares and prior to the expiration of 30 Trading
Days after the ex-dividend date for such dividend or distribution, or the record
date for such subdivision,  combination or  reclassification,  then, and in each
such case, the current per share market price shall be appropriately adjusted to
reflect the current  market price per Common  Share.  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  on the  Nasdaq  National  Market or, if the Common
Shares  are not  listed  on the  Nasdaq  National  Market,  as  reported  in the
principal  consolidated  transaction reporting system with respect to securities
listed on the principal national  securities exchange on which the Common Shares
are listed or  admitted  to trading  or, if the Common  Shares 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  Quotations System ("NASDAQ") or such other system then

<PAGE>

in use,  or, if on any such date the  Common  Shares  are not quoted by any such
organization,  the average of the closing bid and asked prices as furnished by a
professional  market maker making a market in the Common Shares  selected by the
Board of Directors of the Company.  The term  "Trading  Day" shall mean a day on
which the principal national  securities exchange on which the Common Shares are
listed or admitted to trading is open for the transaction of business or, if the
Common  Shares are not listed or admitted to trading on any national  securities
exchange,  a Business  Day.  If the Common  Shares are not  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  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 market price"
per share of Preferred Stock shall be determined in the same manner as set forth
above for Company  Common Shares in clause (i) of this Section 11(d) (other than
the last sentence  thereof).  If the current market price per share of Preferred
Stock cannot be  determined  in the manner  provided  above or if the  Preferred
Stock is not publicly  held or listed or traded in a manner  described in clause
(i) of this Section  11(d),  the "current  market  price" per share of Preferred
Stock  shall be  conclusively  deemed  to be an  amount  equal to 1,000 (as such
amount may be  appropriately  adjusted  for such events as stock  splits,  stock
dividends and  recapitalizations  with respect to Company Common Stock occurring
after the date of this  Agreement)  multiplied  by the current  market price per
share of Company Common Shares.  If neither  Company Common Shares nor Preferred
Stock is publicly held or so listed or traded,  "current market price" per share
of the Preferred Stock shall mean the fair value per share as determined in good
faith  by the  Company's  Board  of  Directors,  whose  determination  shall  be
described in a statement filed with the Rights Agent and shall be binding on the
Rights Agent and the holders of the Rights.  For all purposes of this Agreement,
the "current  market  price" of a Unit of Preferred  Stock shall be equal to the
"current market price" of one share of Preferred Stock divided by 1000.

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

(f) If as a result of an  adjustment  made  pursuant  to Section  11(a) or 13(a)
hereof,  the holder of any Right  thereafter  exercised shall become entitled to
receive any shares of capital stock of the Company other than  Preferred  Stock,

<PAGE>

thereafter  the number of such other shares so  receivable  upon exercise of any
Right and the purchase price thereof shall be subject to adjustment from time to
time in a  manner  and on terms  as  nearly  equivalent  as  practicable  to the
provisions with respect to the Preferred Stock contained in Section 11(a),  (b),
(c), (d),  (e),  (g),  (h),  (i),  (j), (k), (l) and (m), and the  provisions of
Sections 7, 9, 10, 13 and 14 with respect to the Preferred  Stock shall apply on
like terms to any such other shares.

(g) All Rights  originally  issued by the Company  subsequent to any  adjustment
made to the Purchase Price  hereunder  shall evidence the right to purchase,  at
the adjusted  Purchase  Price,  the number of Units of Preferred Stock (or other
securities or assets)  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 Units of Preferred
Stock  (calculated to the nearest one hundred  thousandth of a Unit) obtained by
(i)  multiplying  (x) the number of Units of Preferred  Stock covered by a Right
immediately  prior  to this  adjustment  by (y) the  Purchase  Price  in  effect
immediately prior to such adjustment of the Purchase Price and (ii) dividing the
product so  obtained  by the  Purchase  Price in effect  immediately  after such
adjustment of the Purchase Price.

(i) The Company may elect on or after the date of any adjustment of the Purchase
Price to adjust the number of Rights,  in substitution for any adjustment in the
number of Units of  Preferred  Stock  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 Units of  Preferred  Stock for which a
Right was exercisable  immediately prior to such adjustment.  Each Right held of
record prior to such adjustment of the number of Rights shall become that number
of Rights  (calculated to the nearest hundred  thousandth)  obtained by dividing
the Purchase  Price in effect  immediately  prior to  adjustment of the Purchase
Price by the  Purchase  Price in  effect  immediately  after  adjustment  of the
Purchase Price. The Company shall make a public  announcement of its election to
adjust the number of Rights, indicating the record date for the adjustment, and,
if known at the time, the amount of the adjustment to be made.  This record date
may be the date on which the Purchase  Price is adjusted or any day  thereafter,
but, if the Right Certificates have been issued, shall be at least 10 days later
than the  date of the  public  announcement.  If Right  Certificates  have  been
issued,  upon each  adjustment of the number of Rights  pursuant to this Section
11(i), the Company shall, as promptly as practicable, cause to be distributed to
holders of record of Right  Certificates on such record date, Right Certificates
evidencing,  subject to Section 14 hereof,  the additional  Rights to which such
holders shall be entitled as a result of such  adjustment,  or, at the option of
the  Company  shall  cause  to be  distributed  to such  holders  of  record  in
substitution  and  replacement for the Right  Certificates  held by such holders
prior to the date of adjustment,  and upon surrender thereof, if required by the

<PAGE>

Company, new Right Certificates  evidencing all the Rights to which such holders
shall be entitled after such adjustment. Right Certificates so to be distributed
shall be issued,  executed and  countersigned  in the manner provided for herein
and  shall  be  registered  in the  names  of the  holders  of  record  of Right
Certificates on the record date specified in the public announcement.

(j) Irrespective of any adjustment or change in the Purchase Price or the number
of Units of Preferred Stock issuable upon the exercise of the Rights,  the Right
Certificates  theretofore  and  thereafter  issued may  continue  to express the
Purchase  Price per Unit and the number of Units of  Preferred  Stock which 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 Units of Preferred Stock
issuable  upon  exercise of the Rights,  the  Company  shall take any  corporate
action which may, in the opinion of its counsel,  be necessary in order that the
Company may validly and legally issue such fully paid and nonassessable Units of
Preferred Stock 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 of that number of Units of
Preferred  Stock and other capital  stock or securities of the Company,  if any,
issuable  upon such  exercise  over and above the  number of Units of  Preferred
Stock and other capital stock or  securities  of the Company,  if any,  issuable
upon such  exercise on the basis of the  Purchase  Price in effect prior to such
adjustment;  provided,  however, that the Company shall deliver to such holder a
due bill or other  appropriate  instrument  evidencing  such  holder's  right to
receive such additional shares  (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 it, in its sole  discretion,  shall determine to be advisable in order that
(i) any  consolidation  or  subdivision  of the Preferred  Stock,  (ii) issuance
wholly for cash of any shares of Preferred Stock at less than the current market
price, (iii) issuance wholly for cash of shares of Preferred Stock or securities
which  by their  terms  are  convertible  into or  exchangeable  for  shares  of
Preferred  Stock,  (iv)  dividends  on  Preferred  Stock  payable  in  shares of
Preferred  Stock or (v)  issuance  of rights,  options or  warrants  referred to
hereinabove  in Section  11(b),  hereafter made by the Company to holders of its
Preferred Stock shall not be taxable to such  stockholders,  or shall reduce the
taxes payable by such holder.

Section 12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever
an  adjustment  is made as provided  in  Sections 11 and 13 hereof,  the Company
shall promptly (a) prepare a certificate  setting forth such  adjustment,  and a

<PAGE>

brief statement of the facts accounting for such  adjustment,  (b) file with the
Rights Agent and with each  transfer  agent for the Common Shares a copy of such
certificate  and (c) mail a brief  summary  thereof  to each  holder  of a Right
Certificate in accordance with Section 25 hereof.

Section  13.  Consolidation,  Merger or Sale or  Transfer  of Assets or  Earning
Power. In the event,  directly or indirectly,  (a) the Company shall consolidate
with, or merge with and into, any other Person,  (other than a subsidiary of the
Company in a  transaction  which will not  diminish  substantially  or otherwise
eliminate  the  benefits  intended to be afforded by the Rights) and the Company
shall not be the  surviving  or  continuing  corporation,  (b) any Person  shall
consolidate with the Company, or merge with and into the Company and the Company
shall be the continuing or surviving corporation of such consolidation or merger
and, in connection with such  consolidation or merger, all or part of the Common
Shares shall be changed into or exchanged  for stock or other  securities of any
other Person (or the Company) or cash or any other property,  or (c) the Company
shall sell or otherwise  transfer (or one or more of its Subsidiaries shall sell
or otherwise  transfer),  in one or more  transactions,  assets or earning power
aggregating  50% or more of the assets or earning  power of the  Company and its
Subsidiaries  (taken as a whole) to any other  Person  other than the Company or
one or more of its wholly-owned  Subsidiaries  (in a transaction  which will not
diminish or  otherwise  eliminate  the  benefits  intended to be afforded by the
Rights), then, and in each such case, proper provision shall be made so that (i)
each holder of a Right (except as otherwise  provided  herein) shall  thereafter
have the right to  receive,  upon the  exercise  thereof at a price equal to the
then current Purchase Price, such number of validly authorized and issued, fully
paid,  non-assessable  and freely  tradable  Common  Shares of such other Person
(including  the  Company  as  successor  thereto),  free and clear of any liens,
encumbrances,  rights of first refusal,  transfer  restrictions or other adverse
claims,  as shall equal the result  obtained by (A) multiplying the then current
Purchase  Price by the number of Units of  Preferred  Stock for which a Right is
then  exercisable  and dividing  that product by (B) 50% of the then current per
share  market  price of the  Common  Shares  of such  other  Person  (determined
pursuant  to  Section  11(d)  hereof)  on  the  date  of  consummation  of  such
consolidation,  merger, sale or transfer;  (ii) the issuer of such Common Shares
shall   thereafter  be  liable  for,  and  shall  assume,   by  virtue  of  such
consolidation,  merger, sale or transfer,  all the obligations and duties of the
Company pursuant to this Agreement; (iii) the term "Company" shall thereafter be
deemed to refer to such  issuer;  and (iv) such  issuer  shall  take such  steps
(including,  but not limited to, the  reservation of a sufficient  number of its
Common  Shares in  accordance  with  Section 9 hereof) in  connection  with such
consummation  as may be  necessary  to assure that the  provisions  hereof shall
thereafter be  applicable,  as nearly as  reasonably  may be, in relation to the
Common Shares thereafter deliverable upon the exercise of the Rights.

The  Company  shall  not  consummate  any such  consolidation,  merger,  sale or
transfer  unless prior  thereto the Company and such issuer shall have  executed
and  delivered to the Rights Agent a  supplemental  agreement  providing for the
terms  set  forth  in this  Section  13 and  further  providing  that as soon as
practicable  after the date of any  consolidation , merger,  sale or transfer of


<PAGE>

assets  mentioned in this  Section 13, such issuer will:  (i) prepare and file a
registration  statement  under the  Securities  Act of 1933,  as  amended,  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) take such action as
may be required to ensure that the  acquisition  of such Common Shares  complies
with any  applicable  state  securities  or Blue Sky law,  and (iii)  deliver to
holders of the Rights historical  financial  statements for such issuer and each
of its  Affiliates  which  comply  in all  respects  with the  requirements  for
registration on Form 10 under the Exchange Act.

In case the Person which is to be a party to a  transaction  referred to in this
Section  13  has a  provision  in any of  its  authorized  securities  or in its
Certificate  of  Incorporation  or by-laws  or other  instrument  governing  its
corporate  affairs,  which  provision  would have the effect of (i) causing such
Person to issue, in connection with, or as a consequence of, the consummation of
a  transaction  referred to in this Section 13,  Common Shares of such Person at
less  than the then  current  market  price per share  (determined  pursuant  to
Section 11(d) or securities  exercisable for, or convertible into, Common Shares
of such  Person at less  than such then  current  market  price  (other  than to
holders of Rights pursuant to this Section 13) or (ii) providing for any special
payment, tax or similar provisions in connection with the issuance of the Common
Shares of such Person  pursuant to the  provisions  of this Section 13, then, in
such event, the Company shall not consummate any such  transaction  unless prior
thereto the Company and such Person  shall have  executed  and  delivered to the
Rights Agent a supplemental  agreement  providing that the provision in question
of such  Person  shall  have  been  cancelled,  waived or  amended,  or that the
authorized  securities shall be redeemed,  so that the applicable provision will
have no effect in connection  with, or as a consequence of, the  consummation of
the proposed transaction.

The provisions of this Section 13 shall similarly apply to successive mergers or
consolidations or sales or other transfers. In the event that a Section 13 Event
shall occur at any time after the 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) hereof.

The Company shall not enter into any transaction of the kind referred to in this
Section 13 if at the time of such  transaction  there are any rights,  warrants,
instruments or securities  outstanding or any agreements or arrangements  which,
as a  result  of the  consummation  of  such  transaction,  would  eliminate  or
substantially  diminish the benefits intended to be afforded by the Rights.  The
provisions of this Section 13 shall  similarly  apply to  successive  mergers or
consolidations or sales or other transfers.

Section 14. Fractional Rights and Fractional  Shares.  (a) The Company shall not
be required to issue  fractions of Rights or to  distribute  Right  Certificates
which evidence fractional Rights. In lieu of such fractional Rights, there shall

<PAGE>

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 on The Nasdaq  National  Market,  if the
Rights  are not  listed  on The  Nasdaq  National  Market,  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 and such determination shall be described
in a  statement  filed with the  Rights  Agent and shall be  conclusive  for all
purposes.

(b) The Company shall not be required to issue  fractions of shares of Preferred
Stock (other than fractions which are integral  multiples of one  one-thousandth
of a share of  Preferred  Stock) upon  exercise  of the Rights or to  distribute
certificates  which evidence  fractional  shares of Preferred  Stock. In lieu of
fractional  shares of  Preferred  Stock that are not  integral  multiples of one
one-thousandth  of a 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
share of Preferred  Stock.  For the purposes of this Section 14(b),  the current
market value of a share of Preferred Stock shall be the closing price of a share
of Preferred  Stock (as  determined  pursuant to the second  sentence of Section
11(d)(i)  hereof)  for the  Trading  Day  immediately  prior to the date of such
exercise.

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

Section 15. Rights of Action. All rights of action in respect of this Agreement,
excepting  the  rights of action  given to the  Rights  Agent  under  Section 18
hereof,   are  vested  in  the  respective   registered  holders  of  the  Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the Distribution Date, of the Common Shares),  without the consent of the Rights

<PAGE>

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

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

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

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

(c) the Company and the Rights Agent may deem and treat the person in whose name
the Right Certificate (or, prior to the Distribution Date, the associated Common
Shares  certificate)  is  registered  as the absolute  owner  thereof and of the
Rights evidenced thereby  (notwithstanding any notations of ownership or writing
on the Right  Certificates or the associated  Common Shares  certificate made by
anyone other than the Company or the Rights Agent) for all purposes  whatsoever,
and neither the Company nor the Rights  Agent shall be affected by any notice to
the contrary; and

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

Section 17. Right  Certificate  Holder Not Deemed a 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  Preferred  Stock or any other
securities  of the Company  which may at any time be issuable on the exercise of

<PAGE>

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 hereof), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or Rights  evidenced by
such  Right  Certificate  shall  have  been  exercised  in  accordance  with the
provisions hereof.

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

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

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

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

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

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

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

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

(d)  The  Rights  Agent  shall  not be  liable  for or by  reason  of any of the
statements  of fact or  recitals  contained  in this  Agreement  or in the 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

<PAGE>

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

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

(g) The Rights Agent is hereby  authorized  and directed to accept  instructions
with  respect to the  performance  of its duties  hereunder  from any one of the
Chairman of the Board,  the Chief  Executive  Officer,  the President,  any Vice
President,  the Secretary or the Treasurer of the Company,  and to apply to such
officers for advice or instructions in connection with its duties,  and it shall
not be liable for any action taken or suffered by it in good faith in accordance
with  instructions of any such officer.  At any time, the Rights Agent may apply
to the Company for written  instructions  from the Company  with  respect to any
matter  arising in connection  with the Rights  Agent's  duties and  obligations
arising under this Agreement.  Such  application by the Rights Agent for written
instructions  from the Company may, at the option of the Rights Agent, set forth
in writing any action  proposed to be taken or omitted by the Rights  Agent with
respect to its duties or obligations under this Agreement and the date on and/or
after which such action  shall be taken and the Rights Agent shall not be liable
for any action taken, suffered or omitted by the Rights Agent in accordance with
a proposal  included in any such  application  on or after the date specified in
such application (which date shall not be less than five Business Days after the
date any such officer of the Company actually receives such application,  unless
any such officer  shall have  consented in writing to an earlier  date)  unless,
prior  to  taking  any  such  action  (or the  effective  date in the case of an
omission), the Rights agent shall have received written instructions in response
to such application specifying the action to be taken or omitted.

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

(i) The Rights Agent may execute and exercise any of the rights or powers hereby
vested in it or perform any duty  hereunder  either  itself or by or through its
attorneys or agents, and the Rights Agent shall not be answerable or accountable

<PAGE>

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) The Rights Agent undertakes only the express duties and obligations  imposed
on it by this Agreement and no implied duties or obligations  shall be read into
this Agreement against the Rights Agent.

(k)  Anything in this  Agreement to the  contrary  notwithstanding,  in no event
shall the Rights Agent be liable for special,  indirect or consequential loss or
damage of any kind whatsoever (including but not limited to lost profits).

(l) If, with respect to any Rights  Certificate  surrendered to the Rights Agent
for exercise or transfer,  the Certificate attached to the Form of Assignment or
Form of Election to purchase, as the case may be, has either not been completed,
or not signed,  the Company and the Rights Agent will deem the beneficial  owner
of the Rights evidenced by the Rights Certificate to be beneficially owned by an
Acquiring  Person or an Affiliate or Associate  thereof and such  Assignment  or
Election to Purchase will not be honored.

Section 21.  Change of Rights Agent.  The Rights Agent or any  successor  Rights
Agent may resign and be discharged  from its duties under this Agreement upon 30
days' notice in writing  mailed to the Company and to each transfer agent of the
Common Shares and Preferred  Stock by registered or certified  mail,  and to the
holders  of the  Right  Certificates  (or  of the  Common  Shares  prior  to the
Distribution  Date) by first-class mail. The Company may remove the Rights Agent
or any  successor  Rights Agent upon 30 days'  notice in writing,  mailed to the
Rights Agent or successor Rights Agent, as the case may be, and to each transfer
agent of the Common Shares and Preferred  Stock by registered or certified mail,
and to the holders of the Right  Certificates by first-class mail. If the Rights
Agent shall resign or be removed or shall otherwise  become incapable of acting,
the Company shall appoint a successor to the Rights Agent.  If the Company shall
fail to make such appointment  within a period of 30 days after giving notice of
such  removal or after it has been  notified in writing of such  resignation  or
incapacity by the resigning or incapacitated  Rights Agent or by the holder of a
Right  Certificate (or prior to the  Distribution  Date, by the holder of Common
Shares) (who shall,  with such notice,  submit his Right  Certificate (or common
share certificate) for inspection by the Company), then the registered holder of
any Right  Certificate  (or holder of Common  Shares  prior to the  Distribution
Date) 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  either  (a) a  corporation  organized  and  doing
business  under the laws of the United States or of the State of New York (or of
any other state of the United States so long as such  corporation  is authorized
to do  business  as a banking  institution  in the State of New  York),  in good
standing,  having an office in the State of New York,  which is authorized under
such laws to exercise corporate trust or stock transfer powers and is subject to
supervision or  examination  by federal or state  authority and which has at the
time of its  appointment  as Rights  Agent a combined  capital and surplus of at
least $50 million or (b) an affiliate of such a corporation.

<PAGE>

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  thereof in writing
with the  predecessor  Rights Agent and each transfer agent of the Common Shares
and  Preferred  Stock and mail a notice  thereof in  writing  to the  registered
holders of the Right  Certificates  (or  holders of Common  Shares  prior to the
Distribution Date).  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  Common  Shares  following  the  Distribution  Date  and  prior  to the
Expiration Date, the Company (a) shall,  with respect to Common Shares so issued
or sold  pursuant to the exercise of stock options or under any employee plan or
arrangement,  or  upon  the  exercise,  conversion  or  exchange  of  securities
hereinafter  issued by the  Company,  and (b) may, in any other case,  if deemed
necessary or  appropriate  by the  Company's  Board of  Directors,  issue Rights
Certificates  representing  the appropriate  number of Rights in connection with
such issuance or sale;  provided,  however,  that (i) no such Rights Certificate
shall be issued if,  and to the extent  that,  the  Company  shall be advised by
counsel that such issuance would create a significant  risk of material  adverse
tax  consequences  to the Company or the person to whom such Rights  Certificate
would be issued and (ii) no such Rights  Certificate  shall be issued if, and to
the extent that,  appropriate  adjustment shall otherwise have been made in lieu
of the issuance thereof.

Section  23.  Redemption  and  Termination.  (a) The Board of  Directors  of the
Company may, at its option, at any time prior to the earlier of (i) the close of
business on the tenth business day following the Shares Acquisition Date or (ii)
the Final Expiration Date, redeem all but not less than all the then outstanding
Rights  at a  redemption  price of $.01 per  Right,  appropriately  adjusted  to
reflect any stock split, stock dividend or similar  transaction  occurring after
the date hereof  (such  redemption  price being  hereinafter  referred to as the
"Redemption  Price").  The Redemption Price may be paid in cash or Common Shares
(valued  in  accordance  with  Section  11(d)).  Subject to the  foregoing,  the
redemption of the Rights by the Board of Directors may be made effective at such
time on such basis and with such  conditions  as the Board of  Directors  in its
sole discretion may establish.
<PAGE>

(b)  Immediately  upon the  action  of the  Board of  Directors  of the  Company
ordering the redemption of the Rights  pursuant to paragraph (a) of this Section
23, and without any further action and without any notice, the right to exercise
the Rights will terminate and the only right thereafter of the holders of Rights
shall be to receive the Redemption Price. The Company shall promptly give public
notice of any such redemption;  provided,  however, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within  10 days  after  such  action  of the  Board of  Directors  ordering  the
redemption  of the Rights,  the Company shall mail a notice of redemption to all
the  holders  of the then  outstanding  Rights at their last  addresses  as they
appear upon the registry books of the Rights Agent or, prior to the Distribution
Date, on the registry  books of the transfer  agent for the Common  Shares.  Any
notice  which is mailed in the manner  herein  provided  shall be deemed  given,
whether or not the holder  receives the notice.  Each such notice of  redemption
will state the method by which the payment of the Redemption Price will be made.
Neither the Company nor any of its Affiliates or Associates may redeem,  acquire
or  purchase  for value any  Rights at any time in any  manner  other  than that
specifically  set forth in this  Section 23 or in  Section 24 hereof,  and other
than in connection with the purchase of Common Shares prior to the  Distribution
Date.

Section 24.  Exchange.  (a) 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  11(a)(ii)
hereof) for Common  Shares or Units of Preferred  Stock at an exchange  ratio of
one Common Share or Unit of Preferred Stock per Right, appropriately adjusted to
reflect any stock split, stock dividend or similar  transaction  occurring after
the date  hereof  (such  exchange  ratio  being  hereinafter  referred to as the
"Exchange Ratio").  Notwithstanding the foregoing,  the Board of Directors shall
not be  empowered  to effect such  exchange at any time after any Person  (other
than the Company,  any Subsidiary of the Company,  any employee  benefit plan of
the Company or any such  Subsidiary,  or any entity holding Common Shares for or
pursuant  to the  terms of any such  plan),  together  with all  Affiliates  and
Associates of such Person,  becomes the  Beneficial  Owner of 50% or more of the
Common Shares then outstanding.

(b)  Immediately  upon the  action  of the  Board of  Directors  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  that number of Common  Shares or Units of Preferred
Stock equal to the number of such Rights held by such holder  multiplied  by the
Exchange  Ratio.  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 which is mailed in the manner herein  provided shall be deemed given,
whether or not the holder receives the notice. Each such notice of exchange will

<PAGE>

state the method by which the  exchange of Common  Shares or Units of  Preferred
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  ll(a)(ii)  hereof) held by each holder of
Rights.

(c) In the event that there shall not be  sufficient  Common Shares or Preferred
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
Common Shares or Preferred Stock for issuance upon exchange of the Rights.

(d) The Company  shall not be required to issue  fractions  of Common  Shares or
fractions  of  Units of  Preferred  Stock or to  distribute  certificates  which
evidence  fractional  Common Shares or fractional  Units of Preferred  Stock. In
lieu of such fractional  Common Shares or fractional  Units of Preferred  Stock,
the Company shall pay to the registered  holders of the Right  Certificates with
regard to which such fractional  Common Shares or fractional  Units of Preferred
Stock would  otherwise be issuable an amount in cash equal to the same  fraction
of the current  market value of a Common Share or Unit of Preferred  Stock.  For
the purposes of this  paragraph  (d), the current market value of a Common Share
or Unit of Preferred Stock shall be determined pursuant to 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 (i)
to pay any  dividend  payable  in  stock  of any  class  to the  holders  of its
Preferred  Stock  or to  make  any  other  distribution  to the  holders  of its
Preferred Stock (other than a regular quarterly cash dividend), (ii) to offer to
the holders of its  Preferred  Stock rights or warrants to  subscribe  for or to
purchase any additional  Preferred  Stock or shares of stock of any class or any
other securities, rights or options, (iii) to effect any reclassification of its
Preferred Stock (other than a reclassification involving only the subdivision of
outstanding Preferred Stock), (iv) to effect any consolidation or merger into or
with,  or to effect any sale or other  transfer (or to permit one or more of its
Subsidiaries to effect any sale or other transfer), in one or more transactions,
of 50% or  more  of  the  assets  or  earning  power  of  the  Company  and  its
Subsidiaries  (taken as a whole) to, any other  Person  (other  than the Company
and/or  one  or  more  of its  subsidiaries  in a  transaction  which  will  not
substantially  diminish or eliminate the benefits intended to be afforded by the
Rights),  (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,  (or prior to the Distribution Date to each holder of Common
Shares) in accordance with Section 26 hereof,  a notice of such proposed action,
which shall specify the record date for the purposes of such stock dividend,  or
distribution of rights or warrants, or the date on 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
Preferred  Stock,  if any such date is to be fixed,  and such notice shall be so

<PAGE>

given in the case of any action  covered by clause (i) or (ii) above at least 10
days prior to the record date for determining holders of the Preferred Stock for
purposes of such action,  and in the case of any such other action,  at least 10
days  prior to the date of the  taking  of such  proposed  action or the date of
participation  therein by the holders of the Preferred  Stock whichever shall be
the earlier.  No such notice  shall be required  pursuant to this section if any
subsidiary  of the  Company  effects a  consolidation  or merger with or into or
effects  a sale or other  transfer  of  assets or  earning  power to,  any other
subsidiary of the Company.

(b) In case any of the events set forth in Section 11(a)(ii) hereof shall occur,
then the Company shall as soon as practicable  thereafter give to each holder of
a Right  Certificate to the extent  feasible,  and in accordance with Section 26
hereof,  a notice of the  occurrence of such event,  which notice shall describe
such event and the consequences of such event to holders of Rights under Section
11(a)(ii) hereof.

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

anything contained herein to the contrary,  this Agreement may not be amended at
a time when the Rights are not redeemable.

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

particular  percentage of such outstanding  Common Shares of which any Person is
the Beneficial Owner, shall be made in accordance with the last sentence of Rule
13-3(d)(1)(i)  of the Exchange Act  Regulations as in effect on the date hereof.
The  Board of  Directors  of the  Company  shall  have the  exclusive  power and
authority to  administer  this  Agreement  and to exercise all rights and powers
specifically  granted to the Board of Directors of the Company,  or the Company,
or as may be necessary or advisable  in the  administration  of this  Agreement,
including,  without  limitation,  the  right  and  power  to (i)  interpret  the
provisions of this Agreement,  and (ii) make all determinations deemed necessary
or advisable for the administration of this Agreement (including a determination
to redeem or not redeem the Rights or to amend the Agreement). All such actions,
calculations,  interpretations  and determinations  (including,  for purposes of
clause (ii) 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 (i) be
final,  conclusive and binding on the Company,  the Rights Agent, the holders of
the Rights and all other parties, and (ii) not subject the Board of Directors of
the Company to any liability to the holders of the Rights.

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

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,  void or
unenforceable language from this Agreement would adversely affect the purpose or

the same instrument.

of this  Agreement  are inserted for  convenience  only and shall not control or

NOT  EXERCISABLE  AFTER THE FINAL  EXPIRATION  DATE (AS  DEFINED  IN THE  RIGHTS
AGREEMENT  REFERRED  TO BELOW).  THE RIGHTS ARE  SUBJECT TO  REDEMPTION,  AT THE
OPTION OF THE  COMPANY,  ON THE TERMS SET FORTH IN THE RIGHTS  AGREEMENT.  UNDER
CERTAIN CIRCUMSTANCES  (SPECIFIED IN THE RIGHTS AGREEMENT),  RIGHTS BENEFICIALLY
OWNED  BY  ACQUIRING  PERSONS  (AS  DEFINED  IN  THE  RIGHTS  AGREEMENT)  OR ANY
SUBSEQUENT HOLDER OF SUCH RIGHTS MAY BECOME NULL AND VOID.

                                    PSC Inc.


This certifies that      , or registered assigns, is the registered owner of the
number of Rights set forth  above,  each of which  entitles  the owner  thereof,
subject to the terms,  provisions and conditions of the Rights Agreement,  dated
as of December 30, 1997 (the "Rights Agreement";  terms defined therein have the
same meaning herein unless otherwise  defined  herein),  between PSC Inc., a New
York corporation (the "Company"),  and ChaseMellon Shareholder Services,  L.L.C.
(the  "Rights  Agent"),  to  purchase  from the  Company  at any time  after the
Distribution Date (as such term is defined in the Rights Agreement) and prior to
5:00 P.M.,  New York City,  New York time, on the Final  Expiration  Date at the
principal  office of the  Rights  Agent,  or at the office of its  successor  as
Rights Agent, one thousandth of one fully paid non-assessable  share of Series B
Preferred  Stock,  par value  $.01 per share  (the  "Preferred  Stock"),  of the
Company, at a purchase price of $ 45 per one one-thousandth share (each such one
one-thousandth  share being a "Unit") (the "Purchase Price"),  upon presentation
and  surrender of this Right  Certificate  with the Form of Election to Purchase
duly executed. The number of Rights evidenced by this Right Certificate (and the
number of Units which may be purchased  upon  exercise  hereof) set forth above,
and the  Purchase  Price  set  forth  above  are  subject  to  modification  and
adjustment  upon the  happening  of  certain  events as  provided  in the Rights
Agreement.

Upon the occurrence of certain events set forth in the Rights Agreement,  if the
Rights  evidenced  by this  Rights  Certificate  are  beneficially  owned  by an
Acquiring  Person or an Affiliate or Associate of any such Acquiring  Person or,
under certain circumstances  described in the Rights Agreement,  a transferee of
any such Acquiring Person, Associate or Affiliate, such Rights shall become null
and void and no holder hereof shall

<PAGE>


have any right with respect to such Rights from and after the occurrence of such
an event.

In certain circumstances described in the Rights Agreement, the Rights evidenced
hereby may entitle the registered holder thereof to purchase capital stock of an
entity other than the Company or receive common stock, cash or other assets, all
as provided in the Rights Agreement.

This Right Certificate is subject to all of the terms, provisions and conditions
of the Rights  Agreement,  which terms,  provisions  and  conditions  are hereby
incorporated  herein by  reference  and made a part  hereof and to which  Rights
Agreement  reference  is  hereby  made  for a full  description  of the  rights,
limitations  of rights,  obligations,  duties and  immunities  hereunder  of the
Rights Agent, the Company and the holders of the Right  Certificates.  Copies of
the  Rights  Agreement  are on file at the  principal  executive  offices of the
Company and the  above-mentioned  offices of the Rights Agent and are  available
upon written request.

This Right Certificate, with or without other Right Certificates, upon surrender
at the principal  office of the Rights Agent, may be exchanged for another Right
Certificate  or Right  Certificates  of like  tenor and date  evidencing  Rights
entitling the holder to purchase a like  aggregate  number of Units of Preferred
Stock as the Rights  evidenced by the Right  Certificate  or Right  Certificates
surrendered  shall  have  entitled  such  holder  to  purchase.  If  this  Right
Certificate  shall be exercised in part, the holder shall be entitled to receive
upon surrender  hereof another Right  Certificate or Right  Certificates for the
number of whole Rights not exercised .

Subject to the provisions of the Rights Agreement,  the Rights evidenced by this
Certificate (i) may be redeemed by the Company at a redemption price of $.01 per
Right,  subject to  adjustment,  payable at the option of the Company in cash or
stock,  or (ii) may be exchanged in whole or in part for Common  Shares or Units
of Preferred Stock.

No fractional  shares of Preferred Stock will be issued upon the exercise of any
Right or Rights  evidenced  hereby  (other  than  fractions  which are  integral
multiples  of one  one-thousandth  of a share of Preferred  Stock),  but in lieu
thereof a cash payment will be made, as provided in the Rights Agreement.

No  holder  of this  Right  Certificate  shall be  entitled  to vote or  receive
dividends or be deemed for any purpose the holder of the  Preferred  Stock or of
any other  securities  of the  Company  which may at any time be issuable on the
exercise hereof,  nor shall anything contained in the Rights Agreement or herein
be construed to confer upon the holder  hereof,  as such, any of the rights of a

<PAGE>

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  the  Rights
agreement), or to receive dividends or subscription rights, or otherwise,  until
the  Right or  Rights  evidenced  by this  Right  Certificate  shall  have  been
exercised as provided in the Rights Agreement.

This Right Certificate shall not be valid or obligatory for any purpose until it
shall have been countersigned by the Rights Agent.

                                    Exhibit B

                  SUMMARY OF RIGHTS TO PURCHASE PREFERRED STOCK

Dividend of Right to Purchase Preferred Stock

As of December  30,1997,  the Board of  Directors  of PSC 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 to  shareholders of record at the close of business on
December  30,  1997  (the  "Record  Date")  and for  each  Common  Share  issued
(including shares  distributed from Treasury by the Company thereafter and prior
to the Distribution Date (as defined below)). Each Right entitles the registered
holder,  subject to the terms of the Rights  Agreement  (as defined  below),  to
purchase from the Company one  one-thousandth  of a share (a "Unit") of Series B
Preferred Stock, par value $.01 per share (the "Preferred  Stock") at a purchase
price of $45.00 per Unit (the  "Purchase  Price"),  subject to  adjustment.  The
Purchase  Price is payable in cash or by certified or bank check  payable to the
order of the Company or by wire transfer to the account of the Company (provided
a notice of such wire  transfer is given by the holder of the  related  Right to
the Rights Agent).  The  description  and terms of the Rights are set forth in a
Rights  Agreement (the "Rights  Agreement")  between the Company and ChaseMellon
Shareholder Services, L.L.C., as Rights Agent (the "Rights Agent").

Distribution of the Rights; Right Certificates

Until the Distribution Date (or earlier redemption or expiration of the Rights),
which is defined below,  the Rights will be evidenced with respect to any of the
Common Share  certificates  outstanding  prior to the Distribution  Date by such
Common  Share   certificates  and  no  separate  Right   Certificates   will  be
distributed.  The Rights Agreement provides that until the Distribution Date (or
earlier  redemption  or  expiration  of the  Rights),  (i)  the  Rights  will be
transferred  with and only  with  the  Common  Shares,  (ii)  new  Common  Share
certificates  issued after the Record Date,  upon  transfer,  replacement or new
issuance  of Common  Shares  will be deemed to be issued  with  Rights  and will
contain a notation  incorporating  the Rights Agreement by reference,  and (iii)
the surrender for transfer of any certificates for Common Shares, outstanding as
of the Record  Date,  even  without  such  notation or a copy of this 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. From
and after the  Distribution  Date, such separate Right  Certificates  alone will
evidence the Rights.

<PAGE>


Definition of Distribution Date

"Distribution Date" means the earlier to occur of (i) 10 business days following
the date of a public  announcement  (the  date of such  announcement  being  the
"Shares  Acquisition  Date") that a person,  together with persons affiliated or
associated with it (other than the Company,  any subsidiary of the Company,  any
employee  benefit  plan  of the  Company  or  such  subsidiary)  (an  "Acquiring
Person"),  has  acquired  beneficial  ownership  of 20%  or  more  of  the  then
outstanding Common Shares of the Company or (ii) 10 business days (or such later
date as may be determined by action of the Board of Directors prior to such time
as any  person or group of  affiliated  persons  becomes  an  Acquiring  Person)
following the earlier of the commencement  of, or the first public  announcement
of the intent to commence,  a tender  offer or exchange  offer by a person other
than the Company if, upon consummation of the offer, such person,  together with
persons  affiliated or associated with it, would be the beneficial  owner of 20%
or more of the outstanding Common Shares.

Exercise and Expiration of the Rights

The Rights are not  exercisable  until the  Distribution  Date.  The Rights will
expire at the close of  business on  December  30,  2007 (the "Final  Expiration
Date"), unless earlier redeemed or exchanged by the Company as described below.

Adjustment of the Purchase Price

The Purchase Price payable, and the number of Units of Preferred Stock issuable,
upon  exercise  of the Rights are  subject  to  adjustment  from time to time to
prevent  dilution  (i) in the event of a stock  dividend  on, or a  subdivision,
combination or reclassification  of, the Preferred Stock, (ii) upon the grant to
holders of the Preferred Stock of certain rights or warrants to subscribe for or
purchase  Preferred Stock at a price, or securities  convertible  into Preferred
Stock with a conversion  price,  less than the then current  market price of the
Preferred Stock or (iii) upon the distribution to holders of the Preferred Stock
of evidences of indebtedness,  cash or assets (excluding  regular quarterly cash
dividends or dividends payable in Preferred Stock) or of subscription  rights or
warrants  (other than those  referred to above).  With  certain  exceptions,  no
adjustment in the Purchase Price will be required until  cumulative  adjustments
require an adjustment of at least 1% in the Purchase  Price.  The Company is not
required to issue fractional Units. In lieu thereof an adjustment in cash may be
made based on the market value of a Unit of Preferred  Stock on the last trading
day prior to the date of exercise.

The number of outstanding  Rights are also subject to adjustment in the event of
a stock split of the Common  Shares or a stock  dividend  on the Common  Shares,
payable in Common Shares or subdivisions,  consolidations or combinations of the
Common Shares occurring, in any such case, prior to the Distribution Date.
<PAGE>

Effects of Certain Events

In the event that a person,  together with persons affiliated or associated with
it,  becomes an  Acquiring  Person,  each holder of a Right,  except as provided
below, will thereafter have the right to receive,  upon exercise thereof,  Units
of Preferred  Stock having a value equal to two times the exercise  price of the
Right.  The exercise  price is the Purchase  Price  multiplied  by the number of
Units of Preferred  Stock  issuable  upon exercise of a Right prior to the event
set forth in the preceding sentence.  Notwithstanding  the foregoing,  following
the occurrence of the event set forth in the first  sentence in this  paragraph,
all Rights that are,  or (under  certain  circumstances  set forth in the Rights
Agreement)  were,  beneficially  owned by any  Acquiring  Person  (or by certain
related parties and transferees) will be null and void.

For example,  at an exercise price of $45 per Right,  each Right not owned by an
Acquiring Person (or by certain related parties and  transferees)  following the
event set forth in the preceding  paragraph would entitle its holder to purchase
$90  worth of Units of  Preferred  Stock  for $45.  Assuming  that the  Units of
Preferred  Stock had a per Unit  value of $10 at such  time,  the holder of each
valid Right would be entitled to purchase 9 Units of Preferred Stock for $45.

In the event that (i) the  Company  is  acquired  in a merger or other  business
combination  transaction in which the Company is not the surviving  corporation,
or (ii) fifty percent (50%) or more of the Company's  assets or earning power is
sold or transferred,  each holder of a Right (other than Rights that theretofore
become  null and void as  described  in the second  preceding  paragraph)  shall
thereafter have the right to receive, upon exercise thereof, common stock of the
acquiring  company  having a value equal to two times the exercise  price of the
Right.

Redemption of the Rights

At any time until the close of business on the tenth  business day following the
Shares  Acquisition  Date,  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"),  payable at the election of the Board of Directors,  in cash or Company
Common  Shares.  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 the action of the Board of Directors
of the Company  ordering  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.

Exchange of the Rights

At any time after a person or group of affiliated or associated  persons becomes
an Acquiring Person,  the Board of Directors of the Company,  at its option, may
exchange  each Right (other than Rights owned by such person or group which have
become void), in whole or in part, for Common Shares or Units of Preferred Stock
at an exchange ratio of on Common Share or one Unit of Preferred Stock per Right
(subject to adjustment).
<PAGE>

Amendment of the Rights Agreement

Any of the  provisions  of the  Rights  Agreement  may be  amended  without  the
approval  of the  holders  of  Company  Common  Shares at any time  prior to the
Distribution  Date.  After the  Distribution  Date, the provisions of the Rights
Agreement   may  be  amended  in  order  to  cure  any   ambiguity,   defect  or
inconsistency,  to make changes which do not  adversely  affect the interests of
holders of Rights  (excluding  the  interests of any  Acquiring  Person),  or to
shorten  or  lengthen  any time  period  under the Rights  Agreement;  provided,
however,  that no amendment to adjust the time period governing redemption shall
be made at such time as the Rights are not redeemable.

Exercise of the Right  Entitles the  Rightholder to the Rights of a Shareholder;
Tax Consequences

Until a Right is exercised,  the holder thereof, as such, will have no rights as
a shareholder of the Company,  including,  without limitation, the right to vote
or to  receive  dividends.  While the  distribution  of the  Rights  will not be
taxable to shareholders or to the Company,  shareholders  may,  depending on the
circumstances,  recognize  taxable  income in the event that the  Rights  become
exercisable for Units of Preferred Stock.

Description of Preferred Stock

The Units of Preferred  Stock that may be acquired  upon  exercise of the Rights
will be  nonredeemable  and will be subordinate to any other shares of preferred
stock that have been or may be issued by the Company.

Each Unit of Preferred Stock will receive  ratably any dividend  declared on the
Company Common Shares.

In the event of  liquidation,  the holder of each Unit of  Preferred  Stock will
receive a preferred  liquidation  payment equal to the greater of $1.00 per Unit
or the per share amount paid in respect of a share of the Company Common Shares.

Each  Unit of  Preferred  Stock  will have one vote,  voting  together  with the
Company Common Shares.

In the event of any merger,  consolidation or other transaction in which Company
Common Shares are  exchanged,  each Unit of Preferred  Stock will be entitled to
receive  the per share  amount  paid in respect of each share of Company  Common
Shares.

The rights of holders  of the  Preferred  Stock to  dividends,  liquidation  and
voting,  and in the  event of  mergers  and  consolidations,  are  protected  by
customary antidilution provisions.
<PAGE>

Because of the nature of the Preferred  Stock  dividend,  liquidation and voting
rights,  the economic value of one Unit of Preferred  Stock that may be acquired
upon the exercise of each Right is expected to approximate the economic value of
one share of Company Common Shares.

Commission as an Exhibit to a Current  Report on Form 8-K.  Copies of the Rights

of Incorporation is amended in the following respects:

         (a) Paragraph 4.(a) is hereby amended to read as follows:

         "4.  (a) Statement of Authorized Stock.  The aggregate number of shares
which  the  Corporation  shall  have the  authority  to  issue is Fifty  Million
(50,000,000)  shares of capital stock of the following  classes in the following
amounts:
         (i) Forty Million (40,000,000) shares shall be Common Shares,  having a
par value of $.01 per share ("Common Shares");
         (ii) One  Hundred  Ten  Thousand  (110,000)  shares  shall be  Series A
Convertible  Preferred  Shares,  having a par value of $.01 per share ("Series A

Preferred Shares"); and
         (iv) Nine Million Seven Hundred  Fifteen  Thousand  (9,715,000)  shares
shall  be  Preferred  Shares,  having  a  par  value  of  $.01  per  share  (the
"Undesignated  Preferred Stock"),  which shares of Undesignated  Preferred Stock
may be issued  from time to time in or one or more  series,  each of which shall
have  such  distinctive  designation  or title as shall be fixed by the Board of
Directors  prior to the  issuance  of any shares  thereof.  Each such  series of

<PAGE>

Undesignated  Preferred Stock shall have such voting powers, full or limited, or
no voting power, and have such preferences and relative participating,  optional
or other special rights and such  qualifications,  limitations  or  restrictions
thereof, as shall be stated in such resolution or resolutions  providing for the
issue of such class or series of Undesignated  Preferred Stock as may be adopted
from time to time by the Board of Directors  prior to the issuance of any shares
thereof  pursuant  to the  authority  hereby  expressly  vested  in  it,  all in
accordance with the laws of the State of New York.

         (b) A new paragraph 4.(c) is hereby added as follows:

         (4.   (c)  Statement of Rights and Preferences of Series B Preferred
Shares.   The  respective   powers,   designations,   preferences  and  relative
participating,  optional  and  other  special  rights,  and the  qualifications,
limitations and restrictions of, the Series B Preferred Shares are as follows:

         Section 1.  Designation and Amount.  The shares of such series shall be
designated as "Series B Preferred Shares" and the number of shares  constituting
such series shall be One Hundred  Seventy-five  Thousand (175,000) shares.  Such
number of shares may be increased or  decreased  by  resolution  of the Board of
Directors'  provided,  that no  decrease  shall  reduce  the number of shares of
Series B  Preferred  Shares  to a number  less than the  number  of shares  then
outstanding plus the number of shares reserved for issuance upon the exercise of
outstanding  options,   rights  or  warrants  or  upon  the  conversion  of  any
outstanding  securities  issued by the  Corporation  convertible  into  Series B
Preferred Shares.

         Section 2.  Dividends and  Distributions.  (A) Subject to the rights of
the holders of any shares of any series of  Preferred  Stock of the  Corporation
(the "Preferred Stock") (or any similar stock) ranking prior and superior to the
Series B  Preferred  Shares  with  respect  to  dividends,  each  holder  of one
one-thousandth of a share (a "Unit") of Series B Preferred Shares, in preference
to the  holders of Common  Shares,  par value $.01 per share of the  Corporation
(the "Common  Shares") and of any other stock of the Corporation  ranking junior
to the Series B Preferred Shares, shall be entitled to receive,  when, as and if
declared  by the  Board of  Directors  out of funds  legally  available  for the
purpose, dividends payable in cash in an amount per Unit (rounded to the nearest
cent)  equal to the per share  amount of cash  dividends  declared on the Common
Shares.  In the event the Corporation  shall at any time after December 30, 1997
(the "Rights  Declaration Date"), (i) declare any dividend on outstanding Common
Shares,  payable in Common Shares, (ii) subdivide  outstanding Common Shares, or
(iii) combine outstanding Common Shares into a smaller number of shares, then in
each such case the  amount to which the  holder of a Unit of Series B  Preferred
Shares was entitled  immediately  prior to such event  pursuant to the preceding
sentence  shall be  adjusted  by  multiplying  such  amount by a  fraction,  the
numerator of which is the number of Common Shares outstanding  immediately after
such event and the  denominator  of which is the number of Common  Shares,  that
were outstanding immediately prior to such event.

         (B) The  Corporation  shall declare a dividend or  distribution  on the
Units of Series B Preferred  Shares as provided in paragraph (A) of this Section
immediately  after it declares a dividend or  distribution  on the Common Shares
(other than a dividend payable in Common Shares).

         Section 3.  Voting Rights.  The holders of Units of Series B Preferred 
Shares shall have the following voting rights:
<PAGE>

         (A) Subject to the provision for adjustment  hereinafter  set forth and
except as otherwise  provided in the Certificate of Incorporation or required by
law, each Unit of Series B Preferred  Shares shall entitle the holder thereof to
one vote on all  matters  upon which the  holders  of the  Common  Shares of the
Corporation are entitled to vote. In the event the Corporation shall at any time
after the Rights Declaration Date (i) declare any dividend on outstanding Common
Shares,  payable in Common Shares, (ii) subdivide  outstanding Common Shares, or
(iii) combine outstanding Common Shares into a smaller number of shares, then in
each such case the number of votes per Unit to which  holders of Units of Series
B  Preferred  Shares  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  Common  Shares  outstanding  immediately  after  such  event and the
denominator  of which is the  number of  Common  Shares  that  were  outstanding
immediately prior to such event.

         (B)  Except  as  otherwise  provided  herein,  in  the  Certificate  of
Incorporation or in any other Amendment  creating a series of Preferred Stock or
any similar stock, and except as otherwise required by law, the holders of Units
of Series B  Preferred  Shares and the  holders  of Common  Shares and any other
capital  stock of the  Corporation  having  general  voting  rights  shall  vote
together as one class on all matters  submitted to a vote of shareholders of the
Corporation.

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

         Section 4. Reacquired  Shares.  Any Units of Series B Preferred  Shares
purchased  or otherwise  acquired by the  Corporation  in any manner  whatsoever
shall be retired and cancelled promptly after the acquisition  thereof. All such
Units shall,  upon their  cancellation,  become authorized but unissued Units of
Preferred  Stock and may be reissued as part of a new series of Preferred  Stock
to be created by resolution of the Board of Directors, subject to the conditions
and restrictions on issuance set forth herein.

         Section  5.  Liquidation,  Dissolution  or  Winding  Up.  (A)  Upon any
voluntary  or  involuntary  liquidation,   dissolution  or  winding  up  of  the
Corporation,  no  distribution  shall be made (i) to the  holders  of  shares of
junior stock unless the holders of Units of Series B Preferred Shares shall have
received,  subject to adjustment as  hereinafter  provided in paragraph (B), the
greater of either (a) $1.00 per Unit or (b) the  amount  equal to the  aggregate
per share amount to be distributed  to holders of Common Shares,  or (ii) to the
holders of shares of parity stock, unless simultaneously therewith distributions
are made  ratably on Units of Series B Preferred  Shares and all other shares of
such parity  stock in  proportion  to the total  amounts to which the holders of
Units of Series B Preferred  Shares are  entitled  under  clause  (i)(a) of this
sentence and to which the holders of shares of such parity  stock are  entitled,
in each case upon such liquidation, dissolution or winding up.
<PAGE>

         (B) In the event the  Corporation  shall at any time  after the  Rights
Declaration Date (i) declare any dividend on outstanding Common Shares,  payable
in Common Shares,  (ii) subdivide  outstanding  Common Shares,  or (iii) combine
outstanding  Common  Shares into a smaller  number of shares,  then in each such
case the aggregate amount to which holders of Units of Series B Preferred Shares
were  entitled  immediately  prior to such event  pursuant  to clause  (i)(b) of
paragraph (A) of this Section 5 shall be adjusted by multiplying  such amount by
a fraction the  numerator of which shall be the number of Common Shares that are
outstanding  immediately  after such event and the denominator of which shall be
the number of Common  Shares  that were  outstanding  immediately  prior to such
event.

         Section 6.  Consolidation,  Merger,  Etc. In case the Corporation shall
enter into any consolidation,  merger, combination or other transaction in which
the Common Shares are converted into,  exchanged for or changed into other stock
or securities,  cash and/or any other  property,  then in any such case Units of
Series B Preferred  Shares shall at the same time be similarly  converted  into,
exchanged for or changed into an amount per Unit (subject to the  provisions for
adjustment  hereinafter  set  forth)  equal to 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  Common  Share is  converted,  exchanged  or
converted.  In the  event the  Corporation  shall at any time  after the  Rights
Declaration  Date (i) declare any dividend on outstanding  Common Shares payable
in Common Shares,  (ii) subdivide  outstanding  Common Shares,  or (iii) combine
outstanding Common Shares into a small number of shares,  then in each such case
the amount set forth in the immediately  preceding  sentence with respect to the
exchange or conversion  of Units of Series B Preferred  Shares shall be adjusted
by  multiplying  such amount by a fraction  the  numerator of which shall be the
number of common Shares that are  outstanding  immediately  after such event and
the  denominator  of which  shall be the  number  of  Common  Shares  that  were
outstanding immediately prior to such event.

         Section 7.  No Redemption. The Units of Series B Preferred Shares shall
not be redeemable from any holder.

         Section 8. Rank.  The Units of Series B  Preferred  Shares  shall rank,
with respect to the payment of  dividends  and the  distribution  of assets upon
liquidation,  dissolution or winding up of the Corporation,  junior to all other
series of  Preferred  Stock  unless the terms of any such series  shall  provide
otherwise and senior to the Common Shares.

         Section 9. Amendment.  If any proposed  amendment to the Certificate of
Incorporation would alter,  change, or repeal any of the preferences,  powers or
special rights given to the Series B Preferred Shares so as to affect the Series
B Preferred Shares adversely,  then the holders of the Series B Preferred Shares
shall be entitled to vote  separately  as a class upon such  amendment,  and the
affirmative  vote of a  majority  of the  outstanding  shares  of the  Series  B
Preferred  Shares,  voting  separately  as a class,  shall be necessary  for the
adoption  thereof,  in  addition  to such other vote as may be  required  by the
Business Corporation Law of the State of New York."

         Section 10.  Fractional  Shares.  The Series B Preferred  Shares may be
issued in Units,  which Units shall  entitle the holder,  in  proportion to such
holder's  fractional  shares,  to exercise  voting  rights,  receive  dividends,
participate  in  distributions  and to have the  benefit of all other  rights of
holders of Series B Preferred Shares.

         Section 11.  Certain Definitions.  As used herein with respect to the
Series B  Preferred  Shares,  the  following  terms  shall  have  the  following
meanings:

         (A) The term "Common  Shares" shall mean the class of stock  designated
as the common shares,  par value $.01 per share,  of the Corporation at the date
hereof  or any  other  class of  stock  resulting  from  successive  changes  or
reclassification of such common stock.
<PAGE>

         (B) The term "Junior  Stock",  as used in Section 5 hereof,  shall mean
the  Common  Shares  and any  other  class or  series  of  capital  stock of the
Corporation  over which the Series B Preferred Shares has preference or priority
in the distribution of assets on any  liquidation,  dissolution or winding up of
the Corporation.

         (C) The term "Parity  Stock",  as used in Section 5 hereof,  shall mean
any class of series of  capital  stock  ranking  pari  passu  with the  Series B
Preferred Shares in the  distribution of assets or any liquidation,  dissolution
or winding up of the Corporation.

         FOURTH:  The  Amendment  was  authorized   pursuant  to  the  authority
conferred  upon the  Board  of  Directors  of the  Corporation  by the  Restated
Certificate of Incorporation  of the Corporation,  as the same has been amended,
pursuant to a resolution  adopted by the  shareholders  of the  Corporation at a
meeting of the shareholders.

         IN WITNESS  WHEREOF,  we have executed and subscribed this  Certificate
and do affirm the foregoing as true under the penalties of perjury this 30th day
of December, 1997.

                       PSC ADOPTS SHAREHOLDER RIGHTS PLAN

Rochester,  New  York--December  30,  1997--PSC  Inc.  (Nasdaq:  PSCX) a leading
manufacturer of laser based bar code scanners, today announced that its Board of
Directors has adopted a  Shareholder  Rights Plan and has declared a dividend of
one  Preferred  Share  Purchase  Right  for  each  outstanding  common  share to
shareholders of record at the close of business on December 30, 1997.

The Rights will be exercisable  only if a person or group acquires 20 percent or
more of the  company's  outstanding  common  shares,  or  commences  a tender or
exchange  offer that would result in the  ownership by a person or a group of 20
percent or more of the company's outstanding common shares.

Each  Right,  which is not  currently  exercisable,  will  entitle the holder to
purchase one  one-thousandth  of a share of the Company's new Series B Preferred
Stock  at  an  exercise  price  of  $45.00.  In  the  event  the  Rights  become
exercisable, holders (other than the acquiring group or person) will be entitled
to purchase,  at the exercise  price,  shares of PSC preferred  stock, or common
stock of the  acquiring  company,  which have a market  value equal to twice the
exercise price.

Unless or until the Rights become  exercisable,  they will trade with PSC common
shares and no  separate  certificates  will be  issued.  A summary of the Rights
Agreement  will be sent to  shareholders  on or about  January 20,  1998.  Under
certain  circumstances,  the Rights are redeemable at a price of $0.01 per Right
and will expire on December 30, 2007, unless redeemed earlier.

The Company said that numerous public  companies have adopted similar plans. The
plans  are  intended  to  protect  shareholders'  rights  to  realize  the full,
long-term  value of their  investment  in the  company,  while not  preventing a
fairly  valued bid.  The Plan was not adopted in response to any known effort to
acquire the Company.

PSC manufactures the world's most comprehensive line of laser based handheld and
fixed position bar code  scanners,  bar code engines and verifiers and automated
carton  dimensioning  systems.   These  products  are  used  in  automatic  data
collection solutions in the retail, manufacturing,  transportation, distribution
and health care  industries,  and government.  Headquartered  in Rochester,  New
York, PSC has manufacturing  facilities in Rochester and Eugene, Oregon. PSC has
sales and service offices throughout the Americas, Europe, Asia and Australia.

                  SUMMARY OF RIGHTS TO PURCHASE PREFERRED STOCK

Dividend of Right to Purchase Preferred Stock

As of December  30,1997,  the Board of  Directors  of PSC 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 to  shareholders of record at the close of business on
December  30,  1997  (the  "Record  Date")  and for  each  Common  Share  issued
(including shares  distributed from Treasury by the Company thereafter and prior
to the Distribution Date (as defined below)). Each Right entitles the registered
holder,  subject to the terms of the Rights  Agreement  (as defined  below),  to
purchase from the Company one  one-thousandth  of a share (a "Unit") of Series B
Preferred Stock, par value $.01 per share (the "Preferred  Stock") at a purchase
price of $45.00 per Unit (the  "Purchase  Price"),  subject to  adjustment.  The
Purchase  Price is payable in cash or by certified or bank check  payable to the
order of the Company or by wire transfer to the account of the Company (provided
a notice of such wire  transfer is given by the holder of the  related  Right to
the Rights Agent).  The  description  and terms of the Rights are set forth in a
Rights Agreement (the "Rights  Agreement")  between the Company and Chase Mellon
Shareholder Services, L.L.C., as Rights Agent (the "Rights Agent").

Distribution of the Rights; Right Certificates

Until the Distribution Date (or earlier redemption or expiration of the Rights),
which is defined below,  the Rights will be evidenced with respect to any of the
Common Share  certificates  outstanding  prior to the Distribution  Date by such
Common  Share   certificates  and  no  separate  Right   Certificates   will  be
distributed.  The Rights Agreement provides that until the Distribution Date (or
earlier  redemption  or  expiration  of the  Rights),  (i)  the  Rights  will be
transferred  with and only  with  the  Common  Shares,  (ii)  new  Common  Share
certificates  issued after the Record Date,  upon  transfer,  replacement or new
issuance  of Common  Shares  will be deemed to be issued  with  Rights  and will
contain a notation  incorporating  the Rights Agreement by reference,  and (iii)
the surrender for transfer of any certificates for Common Shares, outstanding as
of the Record  Date,  even  without  such  notation or a copy of this 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. From
and after the  Distribution  Date, such separate Right  Certificates  alone will
evidence the Rights.



<PAGE>


Definition of Distribution Date

"Distribution Date" means the earlier to occur of (i) 10 business days following
the date of a public  announcement  (the  date of such  announcement  being  the
"Shares  Acquisition  Date") that a person,  together with persons affiliated or
associated with it (other than the Company,  any subsidiary of the Company,  any
employee  benefit  plan  of the  Company  or  such  subsidiary)  (an  "Acquiring
Person"),  has  acquired  beneficial  ownership  of 20%  or  more  of  the  then
outstanding Common Shares of the Company or (ii) 10 business days (or such later
date as may be determined by action of the Board of Directors prior to such time
as any  person or group of  affiliated  persons  becomes  an  Acquiring  Person)
following the earlier of the commencement  of, or the first public  announcement
of the intent to commence,  a tender  offer or exchange  offer by a person other
than the Company if, upon consummation of the offer, such person,  together with
persons  affiliated or associated with it, would be the beneficial  owner of 20%
or more of the outstanding Common Shares.

Exercise and Expiration of the Rights

The Rights are not  exercisable  until the  Distribution  Date.  The Rights will
expire at the close of  business on  December  30,  2007 (the "Final  Expiration
Date"), unless earlier redeemed or exchanged by the Company as described below.

Adjustment of the Purchase Price

The Purchase Price payable, and the number of Units of Preferred Stock issuable,
upon  exercise  of the Rights are  subject  to  adjustment  from time to time to
prevent  dilution  (i) in the event of a stock  dividend  on, or a  subdivision,
combination or reclassification  of, the Preferred Stock, (ii) upon the grant to
holders of the Preferred Stock of certain rights or warrants to subscribe for or
purchase  Preferred Stock at a price, or securities  convertible  into Preferred
Stock with a conversion  price,  less than the then current  market price of the
Preferred Stock or (iii) upon the distribution to holders of the Preferred Stock
of evidences of indebtedness,  cash or assets (excluding  regular quarterly cash
dividends or dividends payable in Preferred Stock) or of subscription  rights or
warrants  (other than those  referred to above).  With  certain  exceptions,  no
adjustment in the Purchase Price will be required until  cumulative  adjustments
require an adjustment of at least 1% in the Purchase  Price.  The Company is not
required to issue fractional Units. In lieu thereof an adjustment in cash may be
made based on the market value of a Unit of Preferred  Stock on the last trading
day prior to the date of exercise.

The number of outstanding  Rights are also subject to adjustment in the event of
a stock split of the Common  Shares or a stock  dividend  on the Common  Shares,
payable in Common Shares or subdivisions,  consolidations or combinations of the
Common Shares occurring, in any such case, prior to the Distribution Date.
<PAGE>

Effects of Certain Events

In the event that a person,  together with persons affiliated or associated with
it,  becomes an  Acquiring  Person,  each holder of a Right,  except as provided
below, will thereafter have the right to receive,  upon exercise thereof,  Units
of Preferred  Stock having a value equal to two times the exercise  price of the
Right.  The exercise  price is the Purchase  Price  multiplied  by the number of
Units of Preferred  Stock  issuable  upon exercise of a Right prior to the event
set forth in the preceding sentence.  Notwithstanding  the foregoing,  following
the occurrence of the event set forth in the first  sentence in this  paragraph,
all Rights that are,  or (under  certain  circumstances  set forth in the Rights
Agreement)  were,  beneficially  owned by any  Acquiring  Person  (or by certain
related parties and transferees) will be null and void.

For example,  at an exercise price of $45 per Right,  each Right not owned by an
Acquiring Person (or by certain related parties and  transferees)  following the
event set forth in the preceding  paragraph would entitle its holder to purchase
$90  worth of Units of  Preferred  Stock  for $45.  Assuming  that the  Units of
Preferred  Stock had a per Unit  value of $10 at such  time,  the holder of each
valid Right would be entitled to purchase 9 Units of Preferred Stock for $45.

In the event that (i) the  Company  is  acquired  in a merger or other  business
combination  transaction in which the Company is not the surviving  corporation,
or (ii) fifty percent (50%) or more of the Company's  assets or earning power is
sold or transferred,  each holder of a Right (other than Rights that theretofore
become  null and void as  described  in the second  preceding  paragraph)  shall
thereafter have the right to receive, upon exercise thereof, common stock of the
acquiring  company  having a value equal to two times the exercise  price of the
Right.

Redemption of the Rights

At any time until the close of business on the tenth  business day following the
Shares  Acquisition  Date,  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"),  payable at the election of the Board of Directors,  in cash or Company
Common  Shares.  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 the action of the Board of Directors
of the Company  ordering  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.

Exchange of the Rights

At any time after a person or group of affiliated or associated  persons becomes
an Acquiring Person,  the Board of Directors of the Company,  at its option, may
exchange  each Right (other than Rights owned by such person or group which have
become void), in whole or in part, for Common Shares or Units of Preferred Stock
at an exchange ratio of on Common Share or one Unit of Preferred Stock per Right
(subject to adjustment).

Amendment of the Rights Agreement

Any of the  provisions  of the  Rights  Agreement  may be  amended  without  the
approval  of the  holders  of  Company  Common  Shares at any time  prior to the
Distribution  Date.  After the  Distribution  Date, the provisions of the Rights
Agreement   may  be  amended  in  order  to  cure  any   ambiguity,   defect  or
inconsistency,  to make changes which do not  adversely  affect the interests of
holders of Rights  (excluding  the  interests of any  Acquiring  Person),  or to
shorten  or  lengthen  any time  period  under the Rights  Agreement;  provided,
however,  that no amendment to adjust the time period governing redemption shall
be made at such time as the Rights are not redeemable.

Exercise of the Right Entitles the Rightholder to the Rights of a Shareholder; 
Tax Consequences
<PAGE>

Until a Right is exercised,  the holder thereof, as such, will have no rights as
a shareholder of the Company,  including,  without limitation, the right to vote
or to  receive  dividends.  While the  distribution  of the  Rights  will not be
taxable to shareholders or to the Company,  shareholders  may,  depending on the
circumstances,  recognize  taxable  income in the event that the  Rights  become
exercisable for Units of Preferred Stock.

Description of Preferred Stock

The Units of Preferred  Stock that may be acquired  upon  exercise of the Rights
will be  nonredeemable  and will be subordinate to any other shares of preferred
stock that have been or may be issued by the Company.

Each Unit of Preferred Stock will receive  ratably any dividend  declared on the
Company Common Shares.

In the event of  liquidation,  the holder of each Unit of  Preferred  Stock will
receive a preferred  liquidation  payment equal to the greater of $1.00 per Unit
or the per share amount paid in respect of a share of the Company Common Shares.

Each  Unit of  Preferred  Stock  will have one vote,  voting  together  with the
Company Common Shares.

In the event of any merger,  consolidation or other transaction in which Company
Common Shares are  exchanged,  each Unit of Preferred  Stock will be entitled to
receive  the per share  amount  paid in respect of each share of Company  Common
Shares.

The rights of holders  of the  Preferred  Stock to  dividends,  liquidation  and
voting,  and in the  event of  mergers  and  consolidations,  are  protected  by
customary antidilution provisions.

Because of the nature of the Preferred  Stock  dividend,  liquidation and voting
rights,  the economic value of one Unit of Preferred  Stock that may be acquired
upon the exercise of each Right is expected to approximate the economic value of
one share of Company Common Shares.

A copy of the Rights  Agreement has been filed with the  Securities and Exchange
Commission as an Exhibit to a Current  Report on Form 8-K.  Copies of the Rights
Agreement and the Certificate of Amendment are available free of charge from the
Company. This summary description of the Rights and the Preferred Stock does not
purport to be complete  and is  qualified  in its  entirety by  reference to the
Rights  Agreement and the  Certificate of Amendment,  including the  definitions
therein of certain terms,  which Rights  Agreement and  Certificate of Amendment
are incorporated herein by reference.
