Item 1.     DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

     On October 20, 1998, the Board of Directors of Overseas  Shipholding Group,
Inc. (the  "CORPORATION" or the "COMPANY")  declared a dividend  distribution of
one right (a "RIGHT") to purchase one  one-tenth of a share of the Common Stock,
$1.00 par value, of the Corporation  (the "COMMON  SHARES") for each outstanding
share of Common Stock, payable to the stockholders of record on November 9, 1998
(the "RECORD  DATE").  The Board of Directors  also  authorized and directed the
issuance of one Right with respect to each Common Share issued  thereafter until
the  Distribution  Date (as defined below) and, in certain  circumstances,  with
respect to Common Shares issued after the Distribution Date. Except as set forth
below, each Right, when it becomes  exercisable,  entitles the registered holder
to purchase from the  Corporation  one one-tenth of a Common Share at a price of
$70 per whole Common Share (the "PURCHASE  PRICE"),  subject to adjustment.  The
description  and terms of the  Rights are set forth in a Rights  Agreement  (the
"RIGHTS  AGREEMENT")   between  the  Corporation  and  ChaseMellon   Shareholder
Services,  L.L.C., as Rights Agent (the "RIGHTS AGENT"), dated as of October 20,
1998.

     Initially,  the Rights will be attached  to all  certificates  representing
Common  Shares then  outstanding,  and no separate  Right  Certificates  will be
distributed.  The Rights will  separate from the Common Shares upon the earliest
to occur of (i) a person  or  entity  (a  "PERSON")  or group of  affiliated  or
associated  Persons (a "GROUP") having acquired  beneficial  ownership of 10% or
more of the outstanding  Common Shares (except pursuant to a Permitted Offer, as
hereinafter  defined); or (ii) 10 business days (or such later date as the Board
of Directors may determine) following the commencement of, or announcement of an
intention to make, a tender offer or exchange  offer the  consummation  of which
would result in a Person or Group becoming an Acquiring  Person (as  hereinafter
defined) (the earliest of such dates being called the  "DISTRIBUTION  DATE").  A
Person or Group whose  acquisition of Common Shares causes a  Distribution  Date
pursuant to clause (i) above is an "ACQUIRING PERSON." The date that a Person or
Group   becomes  an  Acquiring   Person  is  the  "SHARES   ACQUISITION   DATE."
Notwithstanding the foregoing,  certain stockholders who currently own in excess
of 10% of the  outstanding  Common Shares and their  affiliates,  associates and
permitted  transferees  will not be deemed  to be  Acquiring  Persons  and their
ownership  will not cause a  Distribution  Date unless they  acquire  additional
Common Shares equal to more than 20% of the number of Common Shares owed by them
on the date of the Rights Agreement.  Furthermore,  a Person who acquires Common
Shares  pursuant  to a tender or  exchange  offer  which is for all  outstanding
Common  Shares at a price and on terms which the Board of  Directors  determines
(prior  to  acquisition)  to be  adequate  and  in  the  best  interests  of the
Corporation  and its  stockholders  (other than such Person,  its affiliates and
associates) (a "PERMITTED  OFFER") will not be deemed to be an Acquiring  Person
and such Person's ownership will not constitute a Distribution Date.

     The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred with and only with the Common Shares. Until the Distribution
Date (or earlier  redemption  or  expiration  of the  Rights),  new Common Share
certificates  issued  after the Record Date upon the transfer or new issuance of
Common  Shares will  contain a notation  incorporating  the Rights  Agreement by
reference. Until the Distribution Date (or earlier redemption or


                                        2

<PAGE>



expiration of the Rights),  the surrender for transfer of any  certificates  for
Common Shares outstanding as of the Record Date, even without such notation or a
copy of 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 (and to each initial  record holder of certain  Common Shares
issued after the Distribution  Date), and such separate Right Certificates alone
will evidence the Rights.

     THE RIGHTS ARE NOT EXERCISABLE UNTIL THE DISTRIBUTION DATE, and will expire
at the close of business on November  9, 2008,  unless  earlier  redeemed by the
Corporation as described below.

     In the event that any person  becomes an Acquiring  Person,  each holder of
Rights  (other than Rights  that have become null and void as  described  below)
will thereafter have the right (the "FLIP-IN  RIGHT") to receive,  upon exercise
of such Rights, the number of Common Shares (or, in certain circumstances, other
securities  of the  Corporation)  having  a  value  (immediately  prior  to such
triggering  event)  equal to two  times  the  aggregate  exercise  price of such
Rights. (So that, for example,  if a Person became an Acquiring Person at a time
when the current per share market price of the Company's Common Shares is $20.00
(and prior to any antidilution  adjustment as described below), each holder of a
Right  (other than a Right which has become null and void as  described  herein)
would have the right to receive upon  exercise of the Right seven Common  Shares
upon  payment of an exercise  price of $70.00.)  The Board,  at its option,  may
exchange  each  Right  (other  than  those  that  have  become  null and void as
described below) for one Common Share in lieu of the Flip-In Right,  provided no
Person is the  beneficial  owner of 50% or more of the Common Shares at the time
of such exchange. Notwithstanding the foregoing, following the occurrence of the
event  described  above,  all Rights  that are or (under  certain  circumstances
specified in the Rights  Agreement)  were  beneficially  owned by any  Acquiring
Person or any affiliate or associate thereof or certain transferees thereof will
be null and void.

     Under the Rights Agreement, the Board of Directors may take such reasonable
actions and may establish such reasonable procedures as it may deem desirable in
connection  with the  exercise,  exchange  or  transfer  of  Rights  in order to
reasonably  assure, in the judgment of the Board of Directors,  the preservation
of the Company's  status as a United  States  citizen  within the  provisions of
Section 2 of the  Shipping Act of 1916,  as amended,  or any  successor  statute
applicable  to the business  being  conducted  by the Company (the  "CITIZENSHIP
PROVISIONS"), including without limitation restricting the issuance of shares of
the Company  pursuant to or in exchange for the Rights to United States citizens
or limiting such issuance to non-United States citizens to such degree as shall,
in the judgment of the Board of Directors, reasonably assure compliance with the
Minimum U.S. Ownership percentage  established from time to time by the Board of
Directors  under the  Company's  By-laws to maintain the  Company's  status as a
United States  citizen.  The  provisions of this  paragraph  will not,  however,
prevent the transfer  after the  Distribution  Date of any Right by a non-United
States  citizen  to a  United  States  citizen,  including  for the  purpose  of
permitting the exercise of the Right by the United States citizen, provided that


                                        3

<PAGE>



any such transfer (or exercise) is consistent with such reasonable procedures as
may be  established  by the  Board  to  reasonably  assure  compliance  with the
Citizenship  Provisions and to otherwise  carry out the provisions of the Rights
Agreement.

     In the event that, at any time following the Shares  Acquisition  Date, (i)
the  Corporation  is  acquired  in  a  merger  or  other  business   combination
transaction  in  which  the  holders  of all of the  outstanding  Common  Shares
immediately  prior to the consummation of the transaction are not the holders of
all of the surviving  corporation's  voting power,  or (ii) more than 50% of the
Corporation's  assets or earning power is sold or transferred,  then each holder
of Rights (except Rights which  previously  have been voided as set forth above)
shall  thereafter  have the right  (the  "FLIP-OVER  RIGHT")  to  receive,  upon
exercise of such Rights,  common shares of the acquiring  company (or in certain
circumstances,  its  parent)  having a value  equal to two times  the  aggregate
exercise price of the Rights; provided,  however, that the Flip Over Right shall
not apply to any transaction  described in clause (i) if (x) such transaction is
with a Person or Persons  (or a wholly  owned  subsidiary  of any such Person or
Persons) that acquired  Common Shares  pursuant to a Permitted Offer and (y) the
price and form of consideration  offered in such transaction is the same as that
paid to all holders of Common Shares whose shares were purchased pursuant to the
Permitted Offer. The holder of a Right will continue to have the Flip-Over Right
whether or not such holder exercises or surrenders the Flip-In Right.

     The  Purchase  Price  payable,  and the  number of  Common  Shares or other
securities 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 Common Shares, (ii) upon
the grant to holders  of the Common  Shares of  certain  rights or  warrants  to
subscribe for or purchase  Common Shares at a price,  or securities  convertible
into Common Shares with a conversion  price,  less than the then current  market
price of the Common  Shares,  or (iii) upon the  distribution  to holders of the
Common  Shares  of  evidences  of  indebtedness  or  assets  (excluding  regular
quarterly  cash  dividends) 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
such Purchase  Price.  No  fractional  Common Shares will be issued and, in lieu
thereof,  an  adjustment  in cash will be made based on the market  price of the
Common Shares on the last trading day prior to the date of exercise.

     At any time  prior to the  earlier  to  occur of (i) a person  becoming  an
Acquiring  Person or (ii) the  expiration  of the Rights,  the  Corporation  may
redeem the Rights in whole,  but not in part,  at a price of $.01 per Right (the
"Redemption  Price"),  which redemption shall be effective at such time, on such
basis and with such  conditions  as the Board of Directors  may establish in its
sole discretion. The Corporation may, at its option, pay the Redemption Price in
Common Shares.

     All of the  provisions of the Rights  Agreement may be amended by the Board
of Directors prior to the Distribution  Date.  After the Distribution  Date, the
provisions of the Rights


                                        4

<PAGE>



Agreement may be amended by the Board 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, subject
to certain limitations,  to shorten or lengthen any time period under the Rights
Agreement.

     Until a Right is  exercised,  the  holder  thereof,  as such,  will have no
rights as a stockholder of the Corporation,  including,  without limitation, the
right to vote or to receive dividends. While the distribution of the Rights will
not be taxable to stockholders of the Corporation,  stockholders may,  depending
upon the  circumstances,  recognize  taxable  income  should the  Rights  become
exercisable or upon the occurrence of certain events thereafter.

     The Rights  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 Board of Directors. The Rights should not interfere
with  any  merger  or  other  business  combination  approved  by the  Board  of
Directors,  as the Rights may be redeemed by the Company at $.01 per Right prior
to the time that a person or group has acquired  beneficial  ownership of 10% or
more of the Common Shares and, moreover,  are not triggered by a Permitted Offer
approved by the Board of Directors as described herein.

     The Rights  Agreement is attached  hereto as an exhibit and is incorporated
herein by reference. The foregoing description of the Rights is qualified in its
entirety by reference to such exhibit.

                                RIGHTS AGREEMENT


          RIGHTS  AGREEMENT,  dated as of October  20,  1998 (the  "Agreement"),
between  Overseas   Shipholding  Group,   Inc.,  a  Delaware   corporation  (the
"Corporation" or the "Company") and ChaseMellon Shareholder Services,  L.L.C., a
New Jersey limited liability company (the "Rights Agent").

          The Board of Directors of the  Corporation has authorized and declared
a  dividend  of one right (a  "Right")  for each  Common  Share (as  hereinafter
defined) of the Corporation  outstanding at the close of business on November 9,
1998 (the  "Record  Date"),  each Right  representing  the right to purchase one
one-tenth of a Common Share, 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
Final  Expiration  Date (as  such  terms  are  hereinafter  defined);  provided,
however,  that  Rights may be issued  with  respect to Common  Shares that shall
become  outstanding  after the Distribution Date and prior to the earlier of the
Redemption Date and the Final  Expiration Date in accordance with the provisions
of Section 22 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 who or which,  together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
of 10% or more of the then outstanding  Common Shares (other than as a result of
a Permitted  Offer (as hereinafter  defined)) or was such a Beneficial  Owner at
any time after the Close of  Business  on the date  hereof,  whether or not such
Person  continues  to be  the  Beneficial  Owner  of  10% or  more  of the  then
outstanding  Common  Shares.   Notwithstanding  the  foregoing,   (A)  the  term
"Acquiring Person" shall not include (i) the Corporation, (ii) any Subsidiary of
the  Corporation,  (iii) any employee  benefit plan of the Corporation or of any
Subsidiary of the Corporation, (iv) any Person or entity organized, appointed or
established by the Corporation for or pursuant to the terms of any such plan, or
(v)  any  Grandfathered  Stockholder  and  (B)  no  Person  (including,  without
limitation,  any Grandfathered  Stockholder)  shall become an "Acquiring Person"
(and  no   Grandfathered   Stockholder   shall  cease  to  be  a   Grandfathered
Stockholder):

               (i) as a  result  of the  acquisition  of  Common  Shares  by the

Corporation,  and (2) after  such share  acquisition  by the  Corporation,  such
Person,  or an Affiliate or  Associate  of such Person,  becomes the  Beneficial
Owner of any  additional  Common  Shares,  then such  Person  shall be deemed an

               (ii) if the Board of  Directors  determines  in good faith that a
Person  who  would   otherwise  be  an   "Acquiring   Person"  has  become  such
inadvertently, and such Person (A) does not attempt to exercise any control over
the business affairs or management of the  Corporation,  including by means of a
proxy  solicitation,  and (B) divests as promptly as  practicable  a  sufficient
number of Common  Shares so that such  Person  would no longer be an  "Acquiring

arrangement  or  understanding;  provided,  however,  that a Person shall not be

would result in any Person becoming an Acquiring Person (including,  in the case
of both (i) and (ii),  any such date  which is after the date of this  Agreement
and prior to the issuance of the Rights), the earlier of such dates being herein
referred  to as the  "DISTRIBUTION  DATE",  (x) 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  (y)  the  right  to  receive  Rights  Certificates  will  be
transferable  only in  connection  with the  transfer of the  underlying  Common
Shares (including a transfer to the Corporation);  PROVIDED,  HOWEVER, that if a

cause to be sent by first-class,  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




<PAGE>



the  Corporation,  a Right  Certificate,  substantially in the form of EXHIBIT A
hereto (a "Right  Certificate"),  evidencing  one Right for each Common Share so
held.  Notwithstanding  the foregoing,  each record holder which is a non-United
States  Citizen may receive a Right  Certificate  in the form  determined by the
Board of  Directors  after taking into  account the  provisions  of Section 7(g)
hereof.  As of and after the  Distribution  Date,  the Rights will be  evidenced
solely by such Right Certificates.

          (b)  As  promptly  as  practicable  following  the  Record  Date,  the
Corporation will send a copy of a Summary of Rights to Purchase Common Shares in
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 Corporation.  With respect to certificates for Common Shares  outstanding
as of the Record Date, until the Distribution Date, the Rights will be evidenced
by such  certificates  registered in the names of the holders  thereof  together
with a copy of the Summary of Rights attached  thereto.  Until the  Distribution
Date (or the earlier of the Redemption Date or the Final  Expiration  Date), the
surrender for transfer of any certificate  for Common Shares  outstanding on the
Record Date shall also  constitute  the transfer of the Rights  associated  with
such Common Shares.

          (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, and the Redemption Date or the Final Expiration Date
shall be deemed also to be certificates for Rights, and shall bear the following
legend:

               This certificate also evidences and entitles the holder
          hereof to certain rights as set forth in a Rights  Agreement
          between  Overseas  Shipholding  Group,  Inc. and ChaseMellon
          Shareholder  Services,  L.L.C., dated as of October 20, 1998
          (the  "Rights  Agreement"),  the terms of which  are  hereby
          incorporated  herein by reference  and a copy of which is on
          file  at  the  principal   executive   offices  of  Overseas
          Shipholding Group, Inc. Under certain circum stances, as set
          forth in the Rights Agreement, such Rights will be evidenced
          by separate  certificates and will no longer be evidenced by
          this certificate. Overseas Shipholding Group, 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  set  forth  in the
          Rights  Agreement,  Rights issued to, or held by, any Person
          who is, was or becomes an  Acquiring  Person or an Affiliate
          or  Associate  thereof (as defined in the Rights  Agreement)
          and certain related persons, whether currently held by or on
          behalf  of such  Person  or by any  subsequent  holder,  may
          become null and void.

          With respect to such  certificates  containing  the foregoing  legend,
until the  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 Corporation purchases or acquires any Common Shares after the
Record Date but prior to the Distribution  Date, any Rights associated with such
Common Shares shall be deemed canceled and retired so that the Corporation shall
not be entitled to exercise any Rights  associated  with the Common Shares which
are no longer outstanding.

          Section 4. FORM OF RIGHT CERTIFICATE.  (a) The Right Certificates (and
the forms of election to purchase and of assignment to be printed on the reverse
thereof) shall be, subject to Section 7(g) hereof, substantially in the form set
forth  in  EXHIBIT  A hereto  and may  have  such  marks  of  identification  or
designation and such legends,  summaries or endorsements  printed thereon as the
Corporation   may  deem   appropriate   (which  do  not  affect  the  duties  or
responsibilities  of the  Rights  Agent)  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 as may be
made pursuant to Section 7(g) hereof or with any rule or regulation




<PAGE>



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  7(g),  Section 11 and
Section 22 hereof,  the Right  Certificates shall entitle the holders thereof to
purchase  such number of tenths of a Common Share as shall be set forth  therein
at the price per Common Share set forth therein (the "Purchase Price"),  but the
amount and type of  securities  purchasable  upon the exercise of each Right and
the Purchase Price thereof shall be subject to adjustment as provided herein.

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

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

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

          (c) Any Right  Certificate  issued pursuant to Section 3(a) or Section
22 hereof that  represents  Rights which are  modified  pursuant to Section 7(g)
hereof,  and any Right  Certificate  issued  pursuant to Section 6 or Section 11
hereof upon  transfer,  exchange,  replacement  or adjustment of any other Right
Certificate referred to in this sentence, shall contain (to the extent feasible)
any  legends  deemed  appropriate  by the  Board of  Directors  to carry out the
provisions of Section 7(g) hereof.  The  provisions of Section 7(g) hereof shall
be operative  whether or not the foregoing legend is contained on any such Right
Certificate.

          Section 5.  COUNTERSIGNATURE AND REGISTRATION.  The Right Certificates
shall be executed on behalf of the Corporation 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  Corporation's  seal or a  facsimile  thereof,  and shall be attested by the
Secretary or an Assistant  Secretary of the  Corporation,  either manually or by
facsimile signature. The Right Certificates shall be countersigned by the Rights
Agent and shall not be valid for any purpose  unless so  countersigned.  In case
any  officer  of the  Corporation  who  shall  have  signed  any  of  the  Right
Certificates   shall  cease  to  be  such  officer  of  the  Corporation  before
countersignature   by  the  Rights  Agent  and  issuance  and  delivery  by  the
Corporation,  such Right  Certificates  may nevertheless be countersigned by the
Rights Agent and issued and delivered by the Corporation with the same force and
effect as though the person who signed such Right Certificates had not ceased to
be such officer of the Corporation;  and any Right  Certificate may be signed on
behalf of the Corporation by any person who, at the actual date of the execution
of such Right Certificate,  shall be a proper officer of the Corporation 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 and receipt by the Rights Agent of any
relevant  information,  the Rights  Agent will keep or cause to be kept,  at its
office designated  pursuant to Section 26 as the appropriate place for surrender
of such Right  Certificate or transfer,  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
certificate number 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 CERTIFICATE. Subject to
the provisions of Section 4(b),  Section 7(e) and Section 14 hereof, at any time
after the close of business  on the  Distribution  Date,  and at or prior to the
close of




<PAGE>



business on the earlier of the Redemption Date or the Final Expiration Date, any
Right Certificate or Right  Certificates may be transferred,  split up, combined
or exchanged for another Right Certificate or Right Certificates,  entitling the
registered  holder to purchase a like number of Common  Shares (or,  following a
Section 13 Event, other securities, as the case may be) as the Right Certificate
or Right Certificates surrendered then entitled such holder (or former holder in
the case of a transfer) to purchase. Any registered holder desiring to transfer,
split up, combine or exchange any Right Certificate or Right  Certificates shall
make such request in writing  delivered to the Rights Agent, and shall surrender
the  Right  Certificate  or Right  Certificates  to be  transferred,  split  up,
combined or  exchanged  at the office of the Rights  Agent  designated  for such
purpose. Neither the Rights Agent nor the Corporation shall be obligated to take
any action whatsoever with respect to the transfer of any such surrendered Right
Certificate  until the  registered  holder shall have  completed  and signed the
certificate  contained  in the form of  assignment  on the reverse  side of such
Right  Certificate  and shall have  provided  such  additional  evidence  of the
identity of the Beneficial Owner (or former  Beneficial  Owner) or Affiliates or
Associates  thereof as the  Corporation  or the Rights  Agent  shall  reasonably
request,  including without  limitation the citizenship of such Beneficial Owner
(or former  Beneficial  Owner).  Thereupon  the Rights Agent  shall,  subject to
Section  4(b),  Section  7(e) and (g) and  Section  14 hereof,  countersign  and
deliver  to  the  Person   entitled   thereto  a  Right   Certificate  or  Right
Certificates,  as the case may be, as so requested.  The Corporation 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. The Rights Agent shall have no duty or obligation under this
Section unless and until it is satisfied that all such taxes and/or governmental
charges have been paid.

          Upon  receipt  by the  Corporation  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 satisfactory to them, and, at the Corporation's request,  reimbursement
to the  Corporation 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  Corporation  will make and deliver a new Right
Certificate of like tenor to the Rights Agent for  countersignature and 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) Subject to Section 7(e) and (g) hereof, the registered holder of any
Right Certificate may exercise the Rights evidenced thereby (except as otherwise
provided  herein)  in whole or in part at any time after the  Distribution  Date
upon surrender of the Right  Certificate,  with the form of election to purchase
and the certificate on the reverse side thereof duly and properly  executed,  to
the Rights Agent at the office of the Rights Agent  designated for such purpose,
together  with payment of the aggregate  Purchase  Price for the total number of
Common  Shares  (or  other  securities,  as the case  may be) as to  which  such
surrendered  Rights are exercised,  at or prior to the earliest of (i) the close
of business on November 9, 2008 (the "Final Expiration  Date"), or (ii) the time
at which the  Rights  are  redeemed  as  provided  in  Section  23  hereof  (the
"Redemption Date").

          (b) The purchase price (the  "Purchase  Price") per whole Common Share
at which a holder of Rights may purchase Common Shares or (subject to Section 14
hereof)  fractions  thereof  upon  exercise of such Rights  shall  initially  be
$70.00, shall be subject to adjustment from time to time as provided in Sections
11 and 13(a)  hereof,  and shall be payable in  accordance  with  paragraph  (c)
below.

          (c)  Upon  receipt  of a Right  Certificate  representing  exercisable
Rights,  with the form of  election  to purchase  and the  certificate  duly and
properly  executed,  accompanied by payment of the Purchase Price for the Common
Shares (or other  securities,  as the case may be) to be purchased and an amount
equal to any applicable tax or charge  required to be paid by the holder of such
Right  Certificate  in  accordance  with  Section 6 hereof by  certified  check,
cashier's  check or money  order  payable to the order of the  Corporation,  the
Rights  Agent shall  thereupon  promptly (i) (A)  requisition  from any transfer
agent of the Common  Shares  certificates  for the number of Common Shares to be
purchased and the Corporation hereby  irrevocably  authorizes its transfer agent
to  comply  with  all  such  requests,  or (B) if the  Corporation,  in its sole
discretion, shall have elected to




<PAGE>



deposit the Common Shares issuable upon exercise of the Rights  hereunder into a
depositary,   requisition  from  the  depositary   agent   depositary   receipts
representing  such number of Common Shares as are to be purchased (in which case
certificates  for the  Common  Shares  represented  by such  receipts  shall  be
deposited by the transfer agent with the depositary  agent) and the  Corporation
will  direct  the  depositary  agent to  comply  with such  requests,  (ii) when
appropriate,  requisition  from the Corporation the amount of cash to be paid in
lieu of issuance of  fractional  shares in  accordance  with  Section 14 hereof,
(iii) after receipt of such certificates or depositary receipts,  cause the same
to be  delivered  to or upon the order of the  registered  holder of such  Right
Certificate,  registered  in such  name or  names as may be  designated  by such
holder, and (iv) when appropriate,  after receipt thereof,  deliver such cash to
or upon the order of the  registered  holder of such Right  Certificate.  In the
event  that the  Corporation  is  obligated  to issue  other  securities  of the
Corporation  pursuant to Section 11(a)  hereof,  the  Corporation  will make all
arrangements   necessary  so  that  such  other  securities  are  available  for
distribution  by the Rights  Agent,  if and when  necessary  to comply with this
Agreement.

          In  addition,  in the case of an  exercise  of the  Rights by a holder
pursuant  to  Section  11(a)(ii),  the  Rights  Agent  shall  return  such Right
Certificate  to the  registered  holder  thereof after  imprinting,  stamping or
otherwise   indicating  thereon  that  the  rights  represented  by  such  Right
Certificate  no longer include the rights  provided by Section  11(a)(ii) of the
Rights  Agreement  and if less than all the  Rights  represented  by such  Right
Certificate  were so  exercised,  the Rights  Agent shall  indicate on the Right
Certificate the number of Rights  represented  thereby which continue to include
the rights provided by Section 11(a)(ii).

          (d) In case the  registered  holder  of any  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, or the
Rights Agent shall place an appropriate  notation on the Right  Certificate with
respect to those Rights exercised.

          (e) Notwithstanding  anything in this Agreement to the contrary,  from
and  after  the  first  occurrence  of a Section  11(a)(ii)  Event,  any  Rights
beneficially owned by (i) an Acquiring Person or an Affiliate or Associate of an
Acquiring Person, (ii) a transferee (including without limitation any transferee
referred to in the last sentence of Section 7(g) hereof) of an Acquiring  Person
(or of any  Affiliate or Associate  thereof) who becomes a transferee  after the
Acquiring  Person  becomes  such,  or  (iii)  a  transferee  (including  without
limitation  any  transferee  referred to in the last  sentence  of Section  7(g)
hereof) of an Acquiring  Person (or of any  Affiliate or Associate  thereof) who
becomes a transferee prior to or concurrently with the Acquiring Person becoming
such and receives such Rights pursuant to either (A) a transfer  (whether or not
for  consideration)  from the Acquiring Person to holders of equity interests in
such  Acquiring  Person or to any Person  with whom the  Acquiring  Person has a
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights or (B) a transfer  which the Board of Directors has determined is part of
a plan,  arrangement or  understanding  which has as a primary purpose or effect
the  avoidance  of this  Section  7(e),  shall  become null and void without any
further  action and no holder of such  Rights  shall have any rights  whatsoever
with respect to such Rights,  whether under any  provision of this  Agreement or
otherwise.  The Corporation shall notify the Rights Agent when this Section 7(e)
applies and shall use all  reasonable  efforts to insure that the  provisions of
this Section 7(e) and Section  4(b) hereof are  complied  with,  but neither the
Company  nor the Rights  Agent shall have any  liability  to any holder of Right
Certificates  or other Person as a result of the  Company's  failure to make any
determinations with respect to an Acquiring Person or its Affiliates, Associates
or transferees hereunder.

          (f)  Notwithstanding  anything  in  this  Agreement  to the  contrary,
neither the Rights Agent nor the Corporation 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)  properly  completed  and signed the  certificate  contained  in the form of
election to  purchase  set forth on the  reverse  side of the Right  Certificate
surrendered for such exercise, and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former  Beneficial  Owner) or Affiliates or
Associates thereof as the




<PAGE>



Corporation  or the Rights Agent shall  reasonably  request,  including  without
limitation,  the  citizenship  of such  Beneficial  Owner (or former  Beneficial
Owner).

          (g)   Notwithstanding   anything  in  this   Agreement  or  any  Right
Certificate to the contrary,  including without limitation Section 11(a)(ii) and
Section 24(a) hereof,  the Board of Directors may take such  reasonable  actions
and may establish such reasonable procedures (and may make such modifications in
the form of Rights  Certificate  attached  hereto as  Exhibit A and the forms of
Assignment,  Election to Purchase and Certificates  attached  thereto) as it may
deem desirable in connection  with the exercise,  exchange or transfer of Rights
in order to reasonably  assure,  in the judgment of the Board of Directors,  the
preservation  of the  Company's  status as a United  States  citizen  within the
provisions  of  Section  2 of the  Shipping  Act of  1916,  as  amended,  or any
successor statute applicable to the business being conducted by the Company (the
"Citizenship Provisions"), including without limitation restricting the issuance
of shares of the Company  pursuant to or in exchange  for the Rights to citizens
of the United States as defined in the  Citizenship  Provisions  ("United States
Citizens")  or limiting  such  issuance to  non-United  States  Citizens to such
degree as shall,  in the judgment of the Board of Directors,  reasonably  assure
compliance with the Minimum U.S. Ownership  percentage  established from time to
time by the  Board of  Directors  under  the  Company's  By-laws.  The  Board of
Directors may establish from time to time reasonable procedures for establishing
the citizenship of holders of Rights and,  without  limiting the foregoing,  may
require that in connection with each issuance of shares under or in exchange for
the Rights or  transfer  of the Rights the  purchaser,  transferee  or holder of
Rights shall certify his citizenship status and such matters relevant thereto as
the Board may require. In no event shall any provision of this Section 7(g) (but
without  limiting the provisions of Section 7(e) or any other  provision of this
Agreement) be deemed to prohibit the transfer after the Distribution Date of any
Right by a  non-United  States  Citizen to a United  States  Citizen,  including
without  limitation  for the purpose of  permitting  the exercise or exchange of
such Right by such United  States  Citizen,  provided that any such transfer (or
exercise or exchange) is consistent  with such  reasonable  procedures as may be
established by the Board of Directors to reasonably  assure  compliance with the
Citizenship  Provisions  and to  otherwise  carry  out  the  provisions  of this
Agreement.

          Section 8.  CANCELLATION  AND DESTRUCTION OF RIGHT  CERTIFICATES.  All
Right  Certificates  surrendered  for the  purpose of  exercise  (other  than an
exercise  pursuant to Section  11(a)(ii)),  transfer,  split up,  combination or
exchange shall,  if surrendered to the  Corporation or to any of its agents,  be
delivered  to the Rights  Agent for  cancellation  or in canceled  form,  or, if
surrendered  to  the  Rights  Agent,  shall  be  canceled  by it,  and no  Right
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
any of the provisions of this Rights Agreement. The Corporation 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
Corporation  otherwise  than upon the exercise  thereof.  The Rights Agent shall
deliver all canceled Right  Certificates  to the  Corporation,  or shall, at the
written request of the  Corporation,  destroy such canceled Right  Certificates,
and in such case  shall  deliver a  certificate  of  destruction  thereof to the
Corporation.

          Section  9.  RESERVATION  AND  AVAILABILITY  OF  COMMON  SHARES.   The
Corporation  covenants  and agrees that at all times after the  occurrence  of a
Section 11(a)(ii) Event it will, to the extent reasonably practicable,  cause to
be reserved and kept available out of its authorized and unissued  Common Shares
(and/or other  securities),  or any  authorized and issued Common Shares (and/or
other  securities)  held in its treasury,  the number of Common Shares (or other
securities,  as the case may be) that will be  sufficient to permit the exercise
in full of all outstanding Rights pursuant to this Agreement.

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





<PAGE>



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

          The Corporation further covenants and agrees that it will pay when due
and  payable any and all U.S.  federal and state taxes and charges  which may be
payable in respect of the issuance or delivery of the Right  Certificates  or of
any Common Shares (or other securities, as the case may be) upon the exercise of
Rights. The Corporation shall not, however, be required to pay any tax or charge
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 Common Shares (or other securities,  as the case
may be) 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  or  depositary  receipts for Common  Shares (or other
securities,  as the case may be) upon the exercise of any Rights, until any such
tax or charge shall have been paid (any such tax or charge being  payable by the
holder of such Right  Certificate at the time of surrender) or until it has been
established to the  Corporation's  reasonable  satisfaction  that no such tax or
charge is due.

          The  Corporation  shall use its best  efforts to (i) file,  as soon as
practicable  following the Shares  Acquisition  Date (or, if required by law, at
such  earlier  time  following  the  Distribution   Date  as  so  required),   a
registration statement under the Act, with respect to the securities purchasable
upon exercise of the Rights on an appropriate form, (ii) cause such registration
statement to become  effective  as soon as  practicable  after such filing,  and
(iii) cause such  registration  statement to remain effective (with a prospectus
at all times meeting the  requirements  of the Act and the rules and regulations
thereunder)  until the date of the expiration of the Rights  provided by Section
11(a)(ii).  The  Corporation  will also take such  action as may be  appropriate
under the blue sky laws of the various states.

          Section 10. COMMON  SHARES RECORD DATE.  Each Person in whose name any
certificate  for  Common  Shares  (or other  securities,  as the case may be) is
issued  upon the  exercise  of Rights  shall for all  purposes be deemed to have
become the holder of record of the Common  Shares (or other  securities,  as the
case may be) represented  thereby on, and such  certificate  shall be dated, the
date  upon  which  the  Right  Certificate   evidencing  such  Rights  was  duly
surrendered  and  payment of the  Purchase  Price (and any  applicable  taxes or
charges) was made;  provided,  however,  that, if the date of such surrender and
payment is a date upon which the Common Shares (or other securities, as the case
may be)  transfer  books of the  Corporation  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 Common Shares (or
other  securities,  as the case may be) transfer  books of the  Corporation  are
open.

          Section 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER AND KIND OF SHARES OR
NUMBER OF RIGHTS.  The Purchase Price,  the number and kind of shares covered by
each Right and the number of Rights  outstanding  are subject to adjustment from
time to time as provided in this Section 11.

          (a)(i)In the event the Corporation shall at any time after the date of
this  Agreement  (A) declare a dividend on the Common  Shares  payable in Common
Shares, (B) subdivide the outstanding Common Shares, (C) combine the outstanding
Common Shares into a smaller  number of Common Shares or (D) issue any shares of
its capital stock in a reclassification of the Common Shares (including any such
reclassification  in  connection  with a  consolidation  or  merger in which the
Corporation  is the  continuing or surviving  corporation),  except as otherwise
provided in this Section 11(a) and Section 7(e) and (g) hereof, (x) 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 (y) the
number  and kind of shares of capital  stock  issuable  on such  date,  shall be
proportionately  adjusted so that the holder of any Right  exercised  after such
time shall be  entitled to receive  the  aggregate  number and kind of shares of
capital stock which, if such Right had been exercised  immediately prior to such
date and at a time when the Common Shares transfer books of the Corporation were
open, such holder would




<PAGE>



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 any Rights
be less than the  aggregate  par value of the  shares  of  capital  stock of the
Corporation  issuable  upon  exercise of such  Rights.  If an event occurs which
would require an adjustment under both Section  11(a)(i) and Section  11(a)(ii),
the  adjustment  provided for in this Section  11(a)(i) shall be in addition to,
and  shall be made  prior  to,  any  adjustment  required  pursuant  to  Section
11(a)(ii).

               (ii)  In the  event  any  Person,  alone  or  together  with  its
Affiliates  and  Associates,  shall  become an  Acquiring  Person,  then  proper
provision shall be made so that each holder of a Right (except as provided below
and in Section  7(e) and (g) hereof)  thereafter  be  entitled to receive,  upon
exercise thereof at a price equal to the then current Purchase Price for a whole
Common Share,  in accordance  with the terms of this  Agreement,  such number of
Common  Shares as shall equal the result  obtained by (x)  multiplying  the then
current  Purchase  Price per whole Common Share by the number of one-tenths of a
Common Share for which a Right was  exercisable  immediately  prior to the first
occurrence  of a Section  11(a)(ii)  Event  (e.g.,  if a Right  was  exercisable
immediately  prior to a Section 11(a)(ii) Event for two one-tenths of a share of
Common Stock and the Purchase Price per whole Common Share was $[X], the product
would be [2X]),  and  dividing  that  product by (y) 50% of the then current per
share market price of the Common  Shares  (determined  pursuant to Section 11(d)
hereof)  on the date of such  first  occurrence  (such  number of  shares  being
referred  to as  the  "Adjustment  Shares");  provided,  however,  that  if  the
transaction  that would otherwise give rise to the foregoing  adjustment is also
subject to the  provisions  of Section 13 hereof,  then only the  provisions  of
Section 13 hereof shall apply and no  adjustment  shall be made pursuant to this
Section 11(a)(ii).

               (iii) If the number of Common Shares which are  authorized by the
Corporation's  certificate of incorporation  but not outstanding or reserved for
issuance  other than upon exercise of the Rights is not sufficient to permit the
exercise  in full of the  Rights  in  accordance  with  Section  11(a)(ii),  the
Corporation  shall,  with  respect to each Right,  make  adequate  provision  to
substitute for the Adjustment Shares,  upon payment of the then current Purchase
Price per whole Common Share,  (A) (to the extent  available)  Common Shares and
then, (B) (to the extent  available) other equity  securities of the Corporation
which the Board of Directors  has  determined  to be  essentially  equivalent to
Common  Shares in respect to  dividend,  liquidation  and  voting  rights  (such
securities being referred to herein as "common share  equivalents") and then, if
necessary (and to the extent  feasible),  (C) other common equity  securities of
the  Corporation,  (D) a reduction in the Purchase  Price, or any combination of
the  foregoing,  having  an  aggregate  value  (as  determined  by the  Board of
Directors) based upon the advice of a nationally  recognized  investment banking
firm  selected by the Board of  Directors  equal to the value of the  Adjustment
Shares;  PROVIDED that (x) the Corporation may, and (y) if the Corporation shall
not have made  adequate  provision as required  above to deliver value within 30
days  following the first  occurrence  of a Section  11(a)(ii)  Event,  then the
Corporation shall be obligated to, deliver, upon the surrender for exercise of a
Right and without  requiring  payment of the  Purchase  Price (1) (to the extent
available)  Common  Shares and then (2) (to the extent  available)  common share
equivalents  and then,  if  necessary  (and to the extent  feasible),  (3) other
common  equity  securities  of  the  Corporation,  or  any  combination  of  the
foregoing,  having an aggregate  value (as  determined by the Board of Directors
based  upon the  advice  of a  nationally  recognized  investment  banking  firm
selected  by the  Board of  Directors)  equal to the  excess of the value of the
Adjustment  Shares  over the  Purchase  Price.  If a  majority  of the  Board of
Directors  shall  determine  in good  faith  that it is likely  that  sufficient
additional  shares  of Common  Shares  could be  authorized  for  issuance  upon
exercise in full of the Rights,  the 30 day period set forth above (such period,
as it may be extended,  being referred to herein as the  "Substitution  Period")
may be extended to the extent necessary, but not more then 90 days following the
first occurrence of a Section 11(a)(ii) Event, in order that the Corporation may
seek stockholder  approval for the  authorization of such additional  shares. To
the extent that some action is to be taken  pursuant to the first and/or  second
sentence of this Section 11(a)(iii),  the Corporation (X) shall provide, subject
to  Section  7(e) and  (g),  that  such  action  shall  apply  uniformly  to all
outstanding  Rights and (Y) may suspend the  exercisability  of the Rights until
the expiration of the Substitution  Period in order to seek any authorization of
additional  shares  and/or  to  decide  the  appropriate  form and  value of any
consideration  to be  delivered  as  referred  to in such  first  and/or  second
sentence.  If any such suspension  occurs,  the Corporation shall issue a public
announcement stating that the exercisability of the Rights




<PAGE>



has been temporarily suspended, as well as a public announcement at such time as
the  suspension is no longer in effect (with prompt notice of such  announcement
to the Rights Agent).

          (b) In case the  Corporation  shall fix a record date for the issuance
of rights (other than the Rights),  options or warrants to all holders of Common
Shares  entitling them (for a period expiring within 45 calendar days after such
record date) to subscribe  for or purchase  Common  Shares (or shares having the
same rights and privileges as the Common Shares ("equivalent common shares")) or
securities convertible into Common Shares or equivalent common shares at a price
per Common Share or  equivalent  common share (or having a conversion  price per
share, if a security convertible into Common Shares or equivalent common shares)
less than the then  current  per share  market  price of the  Common  Shares (as
determined  pursuant to Section 11(d) hereof) 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  Common  Shares
outstanding  on such  record  date plus the  number of Common  Shares  which the
aggregate  offering price of the total number of Common Shares and/or equivalent
common shares so to be offered (and/or the aggregate initial conversion price of
the convertible  securities so to be offered) would purchase at such current per
share market price,  and the  denominator of which shall be the number of Common
Shares  outstanding  on such  record date plus the number of  additional  Common
Shares  and/or  equivalent  common  shares to be  offered  for  subscription  or
purchase  (or  into  which  the  convertible  securities  so to be  offered  are
initially  convertible);   provided,   however,  that  in  no  event  shall  the
consideration  to be paid upon the exercise of Rights be less than the aggregate
par value of the  shares  of  capital  stock of the  Corporation  issuable  upon
exercise  of such  Rights.  In case  such  subscription  price  may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such  consideration  shall  be  determined  in good  faith  by the  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 Rights.
Common Shares owned by or held for the account of the  Corporation  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.

          (c) In case the Corporation  shall fix a record date for the making of
a  distribution  to all  holders  of  the  Common  Shares  (including  any  such
distribution  made in  connection  with a  consolidation  or merger in which the
Corporation  is  the  continuing  or  surviving  corporation)  of  evidences  of
indebtedness  or assets  (other  than a regular  quarterly  cash  dividend  or a
dividend payable in Common Shares) or subscription rights or warrants (excluding
those referred to in Section 11(b)  hereof),  the Purchase Price to be in effect
after such record date shall be determined by multiplying  the Purchase Price in
effect  immediately  prior to such record date by a fraction,  the  numerator of
which shall be the then current per share market price (as  determined  pursuant
to Section 11(d) hereof) of the Common Shares on such record date, less the fair
market  value (as  determined  in good  faith by the 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 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  Common  Share  and  the
denominator  of which shall be such current per share market price of the Common
Shares;  provided,  however, that in no event shall the consideration to be paid
upon the  exercise  of any  Rights be less than the  aggregate  par value of the
shares of capital  stock of the  Corporation  to be issued upon exercise of such
Rights. 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) For the purpose of any  computation  hereunder,  the  "current per
share  market  price" of any  security  (a  "Security"  for the  purpose of this
Section 11(d)),  including,  without  limitation the Common Shares,  on any date
shall be deemed to be the average of the daily closing  prices per share of such
Security  for  the  thirty  (30)  consecutive  Trading  Days  (as  such  term is
hereinafter defined) immediately prior to but not including such date; provided,
however,  that in the  event  that the  current  per share  market  price of the
Security is determined  during a period following the announcement by the issuer
of such Security of (A) a dividend or




<PAGE>



distribution  on such Security  payable in shares of such Security or securities
convertible  into  such  shares,   or  (B)  any   subdivision,   combination  or
reclassification  of such Security and prior to but not including the expiration
of thirty (30)  Trading  Days after the  ex-dividend  date for such  dividend or
distribution,   or  the  record  date  for  such  subdivision,   combination  or
reclassification,  then,  and in each such case,  the current  per share  market
price shall be  appropriately  adjusted to reflect the current  market price per
share  equivalent of such Security.  The closing price for each day shall be the
last sale price,  regular way, or, in case no such sale takes place on such day,
the average of the closing bid and asked prices,  regular way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities  listed or admitted to trading on the New York Stock  Exchange or,
if the  Security  is not  listed or  admitted  to  trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national  securities exchange
on which the  Security is listed or  admitted to trading or, if the  Security is
not listed or admitted to trading on any national securities exchange,  the last
quoted  price or, if not so  quoted,  the  average of the high bid and low asked
prices in the  over-the-counter  market,  as reported by The NASDAQ Stock Market
("NASDAQ")  or such  other  system  then in use,  or,  if on any  such  date the
Security is not quoted by any such organization,  the average of the closing bid
and asked prices as furnished by a professional  market maker making a market in
the  Security  selected by the Board of  Directors.  If on any such date no such
market maker is making a market in the Security,  the fair value of the Security
on such date as  determined  in good  faith by the Board of  Directors  shall be
used.  The term "Trading  Day" shall mean a day on which the principal  national
securities  exchange  on which the  Security is listed or admitted to trading is
open for the  transaction  of  business  or, if the  Security  is not  listed or
admitted to trading on any national securities exchange, a Business Day.

          (e)  Notwithstanding  anything herein to the contrary (except the last
sentence of this Section  11(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
tenthousandth  of a Common  Share or any other share or security as the case may
be.  Notwithstanding  the first sentence of this Section  11(e),  any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
(3) years from the date of the  transaction  which  mandates such  adjustment or
(ii) the Final Expiration Date.

          (f) If as a result of an adjustment made pursuant to Section  11(a)(i)
or 13(a)  hereof,  the holder of any Right  thereafter  exercised  shall  become
entitled to receive any shares of capital  stock of the  Corporation  other than
Common Shares, thereafter the number of other shares so receivable upon exercise
of any Right shall be subject to adjustment from time to time in a manner and on
terms as nearly  equivalent as practicable to the provisions with respect to the
Common  Shares  contained  in Section  11(a)  through  (c),  inclusive,  and the
provisions  of  Sections 7, 9, 10, 13 and 14 with  respect to the Common  Shares
shall apply on like terms to any such other shares.

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

          (h) Unless  the  Corporation  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
Common Shares  (calculated to the nearest one  tenthousandth  of a Common Share)
obtained by (i)  multiplying  (x) the number of Common Shares 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.




<PAGE>



          (i) The  Corporation  may elect on or after the date of any adjustment
of the Purchase Price to adjust the number of Rights,  in lieu of any adjustment
in the number of Common Shares purchasable upon the exercise of a Right. Each of
the Rights  outstanding  after such  adjustment of the number of Rights shall be
exercisable  for the number of Common  Shares for which a Right was  exercisable
immediately  prior to such  adjustment.  Each Right held of record prior to such
adjustment  of  the  number  of  Rights  shall  become  that  number  of  Rights
(calculated to the nearest one ten-thousandth) obtained by dividing the Purchase
Price in effect immediately prior to the adjustment of the Purchase Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Corporation shall make a public  announcement (with prompt notice thereof to the
Rights  Agent) of its  election to adjust the number of Rights,  indicating  the
record date for the  adjustment,  and,  if known at the time,  the amount of the
adjustment  to be made.  This record date may be the date on which the  Purchase
Price is adjusted or any day  thereafter,  but, if the Right  Certificates  have
been  issued,  shall be at least ten (10) days later than the date of the public
announcement.  If Right  Certificates have been issued,  upon each adjustment of
the number of Rights pursuant to this Section 11(i),  the Corporation  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  Corporation,  shall
cause  to  be  distributed  to  such  holders  of  record  in  substitution  and
replacement for the Rights  Certificates  held by such holders prior to the date
of adjustment,  and upon surrender thereof, if required by the Corporation,  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 Common Shares issuable upon the exercise of the Rights,  the Right
Certificates  theretofore  and  thereafter  issued may  continue  to express the
Purchase  Price and the  number of Common  Shares  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  aggregate  par value,  if any, of the number of
Common Shares or other securities issuable in respect of the Purchase Price upon
exercise of a Right, the Corporation  shall take any corporate action which may,
in the opinion of its counsel,  be necessary in order that the  Corporation  may
validly and legally  issue such number of fully paid and  non-assessable  Common
Shares or other securities at such adjusted Purchase Price.

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

          (m) Notwithstanding  anything in this Section 11 to the contrary,  the
Corporation  shall be entitled to make such reductions in the Purchase Price, in
addition to those  adjustment  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 Common  Shares,  (ii)
issuance wholly for cash of Common Shares at less than the current market price,
(iii)  issuance  wholly for cash of Common Shares or  securities  which by their
terms are  convertible  into or  exchangeable  for  Common  Shares,  (iv)  stock
dividends,  or (v) issuance of rights,  options or warrants  referred to in this
Section 11,  hereafter  made by the  Corporation to holders of its Common Shares
shall not be taxable to such shareholders.





<PAGE>



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

          (o) The Corporation  covenants and agrees that, after the Distribution
Date, it will not, except as permitted by Section 7(g), Section 23 or Section 27
hereof,  take (or permit any Subsidiary to take) any action the purpose of which
is to, or if at the time such action is taken it is reasonably  foreseeable that
the effect of such action is to materially  diminish or otherwise  eliminate the
benefits intended to be afforded by the Rights.

          (p) The exercise of Rights under Section  11(a)(ii)  shall only result
in the loss of rights under  Section  11(a)(ii)  to the extent so exercised  and
shall not  otherwise  affect the  rights  represented  by the Rights  under this
Rights Agreement, including the rights represented by Section 13.

          Section  12.  CERTIFICATE  OF  ADJUSTED  PURCHASE  PRICE OR  NUMBER OF
SHARES.  Whenever an  adjustment is made as provided in Section 11 or 13 hereof,
the  Corporation  shall  promptly (a) prepare a  certificate  setting forth such
adjustment,   and  a  brief,   reasonably   detailed  statement  of  the  facts,
computations and methodology  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 26 hereof.  The Rights Agent shall be
fully protected in relying on any such certificate and on any adjustment therein
contained and shall have no duty with respect to and shall not be deemed to have
knowledge  of such  adjustment  unless  and until it shall  have  received  such
certificate.

          Section  13.  CONSOLIDATION,  MERGER OR SALE OR  TRANSFER OF ASSETS OR
EARNING  POWER.  (a) In the event that, on or following  the Shares  Acquisition
Date,  directly or indirectly,  (x) the Corporation  shall  consolidate with, or
merge with and into, any Person,  (y) the Corporation shall consolidate with, or
merge with, any Person, and the Corporation shall be the continuing or surviving
corporation  of such  consolidation  or  merger  (other  than,  in a case of any
transaction  described  in (x) or (y),  a merger or  consolidation  which  would
result in all of the  securities  generally  entitled to vote in the election of
directors ("voting securities") of the Corporation outstanding immediately prior
thereto  continuing to represent  (either by remaining  outstanding  or by being
converted into securities of the surviving  entity) all of the voting securities
of the Corporation or such surviving entity  outstanding  immediately after such
merger or consolidation and the holders of such securities not having changed as
a result of such merger or consolidation),  or (z) the Corporation shall sell or
otherwise  transfer (or one or more of its Subsidiaries  shall sell or otherwise
transfer),  in one  transaction or a series of related  transactions,  assets or
earning  power  aggregating  more than 50% of the assets or earning power of the
Corporation  and its  Subsidiaries  (taken as a whole) to any Person (other than
the Corporation or any Subsidiary of the Corporation in one or more transactions
each of which does not violate  Section 11(o)  hereof),  then,  and in each such
case, proper provision shall be made so that (i) each holder of a Right,  except
as provided in Section 7(e) hereof,  shall thereafter have the right to receive,
upon the exercise thereof at a price equal to the then current Purchase Price




<PAGE>



for a whole Common Share,  in accordance with the terms of this Agreement and in
lieu of Common  Shares,  such number of freely  tradeable  Common  Shares of the
Principal   Party  (as   hereinafter   defined),   not  subject  to  any  liens,
encumbrances,  rights of first refusal or other adverse  claims,  as shall equal
the result  obtained by (A)  multiplying  the then current  Purchase Price for a
whole  Common  Share by the number of  one-tenths  of a Common Share for which a
Right is then exercisable (without taking into account any adjustment previously
made pursuant to Section  11(a)(ii)) and dividing that product by (B) 50% of the
then current per share market price of the Common Shares of such Principal Party
(determined  pursuant to Section  11(d) hereof) on the date of  consummation  of
such Section 13 Event; (ii) such Principal Party shall thereafter be liable for,
and shall assume,  by virtue of such Section 13 Event,  all the  obligations and
duties  of  the  Corporation   pursuant  to  this  Agreement;   (iii)  the  term
"Corporation"  shall  thereafter be deemed to refer to such Principal  Party, it
being specifically intended that the provisions of Section 11 hereof shall apply
only to such  Principal  Party  following  the first  occurrence of a Section 13
Event; and (iv) such Principal Party shall take such steps  (including,  but not
limited to, the  reservation  of a  sufficient  number of its Common  Shares) in
connection with the  consummation of any such transaction as may be necessary to
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.

          (b) "Principal Party" shall mean:

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

               (ii) in the case of any  transaction  described  in clause (z) of
the first sentence of Section 13(a),  the Person that is the party receiving the
greatest  portion of the assets or earning  power  transferred  pursuant to such
transaction or  transactions;  provided,  however,  that in any of the foregoing
cases, (1) if the Common Shares of such Person are not at such time and have not
been  continuously  over the preceding twelve (12) month period registered under
Section  12 of the  Exchange  Act,  and  such  Person  is a direct  or  indirect
Subsidiary  of another  Person  the Common  Shares of which are and have been so
registered, "Principal Party" shall refer to such other Person; (2) in case such
Person is a Subsidiary,  directly or  indirectly,  of more than one Person,  the
Common  Shares  of two or  more  of  which  are and  have  been  so  registered,
"Principal  Party" shall refer to whichever of such Persons is the issuer of the
Common Shares having the greatest  aggregate  market value; and (3) in case such
Person is owned,  directly or  indirectly,  by a joint venture  formed by two or
more Persons that are not owned, directly or indirectly, by the same Person, the
rules  set  forth in (1) and (2)  above  shall  apply to each of the  chains  of
ownership  having an  interest  in such  joint  venture  as if such party were a
"Subsidiary" of both or all of such joint venturers and the Principal Parties in
each such chain shall bear the  obligations  set forth in this Section 13 in the
same ratio as their  direct or  indirect  interests  in such  Person bear to the
total of such interests.

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

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





<PAGE>



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

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

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

          (d)  Notwithstanding  anything  in  this  Agreement  to the  contrary,
Section 13 shall not be applicable to a  transaction  described in  subparagraph
(x) or (y) of  Section  13(a) if: (i) such  transaction  is  consummated  with a
Person or Persons which acquired Common Shares pursuant to a Permitted Offer (or
a wholly owned  Subsidiary  of any such Person or  Persons);  (ii) the price per
Common Share offered in such  transaction  is not less than the price per Common
Share paid to all holders of Common Shares whose shares were purchased  pursuant
to such Permitted  Offer;  and (iii) the form of  consideration  offered in such
transaction  is the  same as the form of  consideration  paid  pursuant  to such
Permitted Offer. Upon consummation of any such transaction  contemplated by this
Section 13(d), all Rights hereunder shall expire.

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

          (b) The Corporation shall not be required to issue fractions of Common
Shares upon exercise of the Rights or to distribute  certificates which evidence
fractional Common Shares.  In lieu of fractional Common Shares,  the Corporation
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 Common  Share.  For the purposes of
this  Section  14(b),  the current  market  value of a Common Share shall be the
closing price of a Common Share (as determined pursuant to Section 11(d) 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  share upon
exercise of a Right (except as provided above).





<PAGE>



          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
the Distribution Date, of the Common Shares),  without the consent of the Rights
Agent  or of the  holder  of any  other  Right  Certificate  (or,  prior  to the
Distribution Date, of the Common Shares), may, in his own behalf and for his own
benefit,  enforce, and may institute and maintain any suit, action or proceeding
against the Corporation 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 holder 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  Corporation  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 office of the Rights Agent  designated  for such  purpose,  duly endorsed or
accompanied  by a proper  instrument of transfer and with the  appropriate  form
fully executed;

          (c) subject to Section 6 and Section 7(f) hereof,  the Corporation 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  Certificate or the associated  Common Shares  certificate  made by anyone
other than the Corporation or the Rights Agent) for all purposes whatsoever, and
neither the  Corporation  nor the Rights Agent,  subject to the last sentence of
Section  7(e)  hereof,  shall be  required  to be  affected by any notice to the
contrary; and

          (d)  notwithstanding  anything  in  this  Agreement  to the  contrary,
neither the  Corporation  nor the Rights  Agent shall have any  liability to any
holder  of a Right or a  beneficial  interest  in a Right or other  Person  as a
result of its inability to perform any of its  obligations  under this Agreement
by reason of any  preliminary  or permanent  injunction or other order,  decree,
judgment  or  ruling  (whether  interlocutory  or  final)  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 Corporation must use its
best  efforts  to have any such  order,  decree,  judgment  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 Common  Shares or any
other  securities  of the  Corporation  which may at any time be issuable on the
exercise of the Rights represented  thereby, nor shall anything contained herein
or in any Right  Certificate be construed to confer upon the holder of any Right
Certificate,  as such, any of the rights of a stockholder of the  Corporation or
any right to vote for the election of directors or upon any matter  submitted to
shareholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
stockholders  (except as provided in Section 25 hereof), or to receive dividends
or other distributions or to exercise any preemptive 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.





<PAGE>



          Section 18. CONCERNING THE RIGHTS AGENT. The Corporation 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,  preparation,  delivery and execution of this  Agreement and the
exercise and performance of it duties hereunder.  The Corporation also agrees to
indemnify  the Rights  Agent for,  and to hold it  harmless  against,  any loss,
liability,   damage,   judgment,   fine,  penalty,  claim,  demand,   settlement
(reasonably  consented to by the  Corporation),  or reasonable  cost or expense,
incurred without gross negligence,  bad faith or willful  misconduct on the part
of the Rights  Agent,  for any action  taken,  suffered or omitted by the Rights
Agent in connection  with the acceptance and  administration  of this Agreement,
including  without  limitation  the  reasonable  costs and expenses of defending
against any claim of  liability  in the  premises.  In no event shall the Rights
Agent be liable for special, indirect,  punitive or consequential loss or damage
of any kind whatsoever (including but not limited to lost profits),  even if the
Rights  Agent has been  advised  of the  likelihood  of such loss or damage  and
regardless  of the form of action.  The  indemnity  provided  for  herein  shall
survive the expiration of the Rights,  the  resignation or removal of the Rights
Agent and the termination of this Agreement.

          The Rights Agent shall be authorized  and protected and shall incur no
liability for, or in respect of, any action taken,  suffered or omitted by it in
connection with, the acceptance and administration of this Agreement in reliance
upon any Right Certificate  delivered to the Rights Agent pursuant to Sections 6
and 7 hereof  for  Common  Shares or for other  securities  of the  Corporation,
instrument of assignment or transfer, power of attorney, endorsement, affidavit,
letter, notice, direction,  consent,  certificate,  statement, or other paper or
document  believed by it to be genuine  and to be signed,  executed  and,  where
necessary, verified or acknowledged, by the proper Person or Persons.

          Section 19. MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.
Any Person  into which the Rights  Agent or any  successor  Rights  Agent may be
merged or with which it may be  consolidated,  or any Person  resulting from any
merger or  consolidation to which the Rights Agent or any successor Rights Agent
shall be a party, or any Person succeeding to the shareholder  services 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 a 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 or in the name of the successor  Rights Agent; and in all such cases
such  Right  Certificates  shall  have  the full  force  provided  in the  Right
Certificates and in this Agreement.

          In case at any time the name of the Rights  Agent  shall be changed 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 only
those duties and obligations expressly imposed by this Agreement (and no implied
duties or obligations) upon the following terms and conditions,  by all of which
the  Corporation  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 Corporation), and the advice or opinion of such counsel shall be
full and complete authorization and protection to




<PAGE>



the Rights Agent and the Rights Agent shall incur no liability for or in respect
of any action  taken,  suffered or omitted by it in good faith and in accordance
with such advice or opinion.

          (b) Whenever in the performance of its duties under this Agreement the
Rights  Agent  shall  deem it  necessary  or  desirable  that any fact or matter
(including,  without  limitation,  the identity of an  Acquiring  Person and the
determination  of the  current  market  price  of any  Security)  be  proved  or
established by the Corporation prior to taking, suffering or omitting 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  Corporation  and  delivered  to the  Rights  Agent;  and such
certificate  shall be full  authorization and protection to the Rights Agent and
the Rights  Agent  shall  incur no  liability  in  respect of any action  taken,
suffered or omitted in good faith by it under the  provisions of this  Agreement
in reliance upon such certificate.

          (c) The Rights Agent shall be liable  hereunder only for its own gross
negligence, bad faith or willful misconduct.

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

          (e)  The  Rights   Agent   shall  not  be  under  any   liability   or
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
Corporation  of any covenant or condition  contained in this Agreement or in any
Rights  Certificate;  nor  shall  it  be  responsible  for  any  change  in  the
exercisability  of the  Rights  (including  the  Rights  becoming  null and void
pursuant to Section  7(e) hereof or any action  taken by the Board of  Directors
pursuant to Section 7(g) hereof) or any adjustment required under the provisions
of  Section 11 or Section 13 hereof or  responsible  for the  manner,  method or
amount of any such adjustment or the ascertaining of the existence of facts that
would require any such adjustment (except with respect to the exercise of Rights
evidenced by Right  Certificates  after receipt of the certificate  described in
Section  12  hereof);  nor shall it by any act  hereunder  be deemed to make any
representation  or warranty as to the authorization or reservation of any Common
Shares to be issued pursuant to this Agreement or any Right Certificate or as to
whether any Common Shares will, when issued,  be validly  authorized and issued,
fully paid and non-assessable.

          (f) The Corporation 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 Treasurer or the Secretary of the  Corporation,  and to
apply to such officers for advice or instructions in connection with its duties,
and such instructions  shall be full  authorization and protection to the Rights
Agent and the Rights  Agent  shall incur no  liability  for or in respect of any
action  taken,  suffered  or  omitted  by it in good  faith or lack of action in
accordance  with  instructions  of any such  officer  or for any delay in acting
while waiting for those  instructions.  Any  application by the Rights Agent for
written  instructions  from the  Corporation  may,  at the  option of the Rights
Agent, set forth in writing any action proposed to be taken, suffered or omitted
by the Rights Agent under this Rights  Agreement  and the date on or after which
such action shall be taken or suffered or such omission shall be effective.  The
Rights  Agent  shall not be  liable  for any  action  taken or  suffered  by, or
omission of, the Rights Agent in accordance with a proposal included in any




<PAGE>



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  officer  of the
Corporation  actually receives such  application,  unless any such officer shall
have  consented  in  writing  to an  earlier  date)  unless,  prior to taking or
suffering  any such action (or the  effective  date in the case of an omission),
the Rights Agent shall have  received  written  instruction  in response to such
application specifying the action to be taken, suffered or omitted.

          (h)  The  Rights  Agent  and any  shareholder,  director,  officer  or
employee of the Rights Agent may buy, sell or deal in any of the Rights or other
securities  of  the  Corporation  or  become   pecuniarily   interested  in  any
transaction in which the Corporation may be interested, or contract with or lend
money to the  Corporation 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  Corporation  or for any other
legal entity.

          (i) The Rights  Agent may  execute and  exercise  any of the rights or
powers hereby vested in it or perform any duty hereunder  either itself or by or
through its attorneys or agents, and the Rights Agent shall not be answerable or
accountable for any act, default, neglect or misconduct of any such attorneys or
agents or for any loss to the Corporation or any other Person resulting from any
such act, default, neglect or misconduct,  absent gross negligence, bad faith or
willful misconduct in the selection and continued employment thereof.

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

          (k) If,  with  respect to any Rights  Certificate  surrendered  to the
Rights Agent for exercise or transfer,  the certificate  attached to the form of
assignment  or form of  election to  purchase,  as the case may be, has not been
completed,  the Rights  Agent shall not take any further  action with respect to
such  requested   exercise  or  transfer   without  first  consulting  with  the
Corporation.

          Section 21. CHANGE OF RIGHTS AGENT.  The Rights Agent or any successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon thirty (30) days' notice in writing  mailed to the  Corporation  and to the
transfer  agent of the Common  Shares by  registered  or  certified  mail,  and,
subsequent to the Distribution Date, to the holders of the Right Certificates by
first-class  mail. The  Corporation may remove the Rights Agent or any successor
Rights  Agent upon  thirty (30) days'  notice in  writing,  mailed to the Rights
Agent or any  successor  Rights  Agent,  as the case may be, and to the transfer
agent of the Common Shares by registered or certified mail,  and,  subsequent to
the Distribution Date, to 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  Corporation  shall  appoint a successor to the Rights
Agent. If the Corporation shall fail to make such appointment within a period of
thirty  (30)  days  after  giving  notice of such  removal  or after it has been
notified  in writing of such  resignation  or  incapacity  by the  resigning  or
incapacitated  Rights Agent or by the holder of a Right  Certificate (who shall,
with  such  notice,   submit  his  Right   Certificate  for  inspection  by  the
Corporation),  then the registered  holder of any Right Certificate may apply to
any court of competent  jurisdiction  for the appointment of a new Rights Agent.
Any successor  Rights Agent,  whether  appointed by the Corporation or by such a
court,  shall be (i) a Person 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 Person is  authorized  to do business in the State of New
York),  in good  standing,  having an office in the State of New York,  which is
subject to supervision  or  examination by federal or state  authority and which
has at the time of its  appointment  as  Rights  Agent a  combined  capital  and
surplus of at least $50,000,000 or (ii) an Affiliate thereof. 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




<PAGE>



such appointment,  the Corporation shall file notice thereof in writing with the
predecessor  Rights  Agent and the  transfer  agent of the Common  Shares,  and,
subsequent to the  Distribution  Date,  mail a notice  thereof in writing to the
registered  holders  of the  Right  Certificates.  Failure  to give  any  notice
provided  for in this  Section 21,  however,  or any defect  therein,  shall not
affect the legality or validity of the  resignation  or removal of the successor
Rights Agent or the appointment of the 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
Corporation may, at its option,  issue new Right Certificates  evidencing Rights
in such  form as may be  approved  by the  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 upon exercise of the Rights
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 earlier of the Redemption Date
and the Final  Expiration Date, the Corporation (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,  notes or debentures issued by the Corporation,  and (b) may, in any
other case, if deemed necessary or appropriate by the Board of Directors,  issue
Right  Certificates  representing the appropriate number of Rights in connection
with such issuance or sale,  provided,  however,  that (i) the Corporation shall
not be  obligated  to issue any such  Right  Certificates  if, and to the extent
that,  the  Corporation  shall be advised by counsel  that such  issuance  would
create  a  significant   risk  of  material  adverse  tax  consequences  to  the
Corporation  or the  Person to whom such  Right  Certificate  would be issued or
material  adverse  consequences to the  Corporation's  status as a United States
Citizen,  and (ii) no Right  Certificate  shall be issued  if, and to the extent
that,  appropriate  adjustment  shall  otherwise  have  been made in lieu of the
issuance thereof.

          Section 23.  REDEMPTION  AND  TERMINATION.  (a) The Board of Directors
may, at its option, redeem all but not less than all the then outstanding Rights
at a redemption  price of $0.01 per Right,  as such amount may be  appropriately
adjusted  to reflect any stock  split,  stock  dividend  or similar  transaction
occurring  after  the date  hereof  (such  redemption  price  being  hereinafter
referred to as the "Redemption  Price"), at any time prior to the earlier of (x)
the  time  that  any  Person  becomes  an  Acquiring  Person,  or (y) the  Final
Expiration  Date. The Corporation  may, at its option,  pay the Redemption Price
either in Common  Shares  (based on the  "current  per share  market  price," as
defined in Section 11(d) hereof, of the Common Shares at the time of redemption)
or cash;  provided that if the Corporation elects to pay the Redemption Price in
Common  Shares,  the  Corporation  shall not be required to issue any fractional
Common Shares and the number of Common Shares  issuable to each holder of Rights
shall be rounded down to the next whole share.  The  redemption of the Rights by
the Board of Directors  may be made  effective  at such time,  on such basis and
with  such  conditions  as the Board of  Directors  in its sole  discretion  may
establish.

          (b)  Immediately  upon the  action  of the Board of  Directors  of the
Company  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 for each Right so held. The
Corporation  shall  promptly  give notice of any such  redemption  to the Rights
Agent and the holders of Rights in the manner set forth in Section 26, provided,
however,  that the failure to give,  or any defect in, any such notice shall not
affect the validity of such redemption. 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 Corporation nor any of
its  Affiliates  or  Associates  may redeem,  acquire or purchase  for value any
Rights at any time in any manner other than that  specifically set forth in this
Section 23 and other than in connection with the purchase of Common Shares prior
to the Distribution Date.

          Section 24.  EXCHANGE.  (a) Subject to Section 7(g) and Section  24(d)
hereof,  the Board of Directors  may, at its option,  at any time after the time
that any Person becomes an Acquiring Person, exchange




<PAGE>



all or part of the then  outstanding  and  exercisable  Rights  (which shall not
include  Rights  that have become null and void  pursuant to the  provisions  of
Section 7(e) and Section  11(a)(ii) hereof) for Common Shares of the Corporation
at an exchange  ratio of one Common Share per Right,  appropriately  adjusted to
reflect any stock split, stock dividend or similar  transaction  occurring after
the date  hereof  (such  exchange  ratio  being  hereinafter  referred to as the
"Exchange Ratio").  Notwithstanding the foregoing,  the Board of Directors shall
not be  empowered  to effect such  exchange at any time after any Person  (other
than the Corporation,  any Subsidiary of the  Corporation,  any employee benefit
plan of the Corporation or any such Subsidiary, any entity holding Common Shares
for or pursuant to the terms of any such plan or any trustee,  administrator  or
fiduciary of such a 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
Corporation  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 the
holders of such Rights shall be to receive that number of Common Shares equal to
the number of such rights held by such holder  multiplied by the Exchange Ratio,
except as otherwise  determined  by the Board of Directors  in  accordance  with
Section 7(g) hereof.  The  Corporation  shall promptly give public notice of any
such  exchange  (with  prompt  notice  thereof to the Rights  Agent);  provided,
however,  that the  failure to give,  or any defect in,  such  notice  shall not
affect the validity of such  exchange.  The  Corporation  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 state the
method by which the  exchange  of the Common  Shares for Rights will be effected
and, in the event of any partial  exchange,  the number of Rights  which will be
exchanged.  Any partial  exchange shall be effected pro rata based on the number
of Rights  (other  than Rights  which have become null and void  pursuant to the
provisions of Section  7(e)) held by each holder of Rights,  except as otherwise
determined by the Board of Directors in accordance with Section 7(g) hereof.

          (c) In the event  that there  shall not be  sufficient  Common  Shares
issued but not  outstanding  or  authorized  but unissued  (and not reserved for
issuance  other than upon  exercise  of the  Rights) to permit any  exchange  of
Rights as  contemplated  in accordance with this Section 24, the (i) Corporation
shall take all such action as may be necessary to  authorize  additional  Common
Shares for issuance upon exchange of the Rights,  or (ii) the Board of Directors
may determine to exchange  Common Shares for then  outstanding  and  exercisable
Rights  at such  exchange  ratio  of less  than  one  Common  Share  per  Right,
appropriately adjusted as set forth in Section 24(a) above, so that all (and not
less than all)  Common  Shares  issued but not  outstanding  or  authorized  but
unissued (and not reserved for issuance  other than upon exercise of the Rights)
are issued in the exchange contemplated by this Section 24.

          (d) In any exchange  pursuant to this Section 24, the Corporation,  at
its option,  may  substitute  common  share  equivalents  (as defined in Section
11(a)(iii)) for Common Shares  exchangeable  for Rights,  at the initial rate of
one common stock equivalent for each Common Share, as appropriately  adjusted to
reflect  adjustments in dividend,  liquidation and voting rights of common share
equivalents  pursuant to the terms thereof, so that each common share equivalent
delivered in lieu of each Common Share shall have essentially the same dividend,
liquidation and voting rights as one Common Share.

          Section  25.  NOTICE OF CERTAIN  EVENTS.  (a) In case the  Corporation
shall propose,  at any time after the Distribution Date, (i) to pay any dividend
payable in stock of any class to the holders of its Common Shares or to make any
other  distribution  to the holders of its Common  Shares  (other than a regular
quarterly  cash  dividend),  (ii) to offer to the  holders of its Common  Shares
rights or warrants to subscribe for or to purchase any additional  Common Shares
or  shares of stock of any class or any  other  securities,  rights or  options,
(iii)  to  effect  any  reclassification  of its  Common  Shares  (other  than a
reclassification  involving only the subdivision of outstanding  Common Shares),
(iv) to effect any  consolidation or merger into or with any other Person (other
than a Subsidiary of the  Corporation  in a  transaction  which does not violate
Section 11(o) hereof), or to effect any sale




<PAGE>



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  Corporation  and its  Subsidiaries  (taken as a
whole) to any other Person or Persons (other than the Corporation  and/or any of
its  Subsidiaries  in one or more  transactions  each of which does not  violate
Section 11(o) hereof), or (v) to effect the liquidation,  dissolution or winding
up of the  Corporation,  then, in each such case, the Corporation  shall give to
the Rights Agent and to each holder of the Right Certificate, in accordance with
Section 26 hereof,  a notice of such proposed action and file a certificate with
the Rights  Agent to that  effect,  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 Common Shares,  if any such date is
to be fixed, and such notice shall be so given in the case of any action covered
by clause (i) or (ii) above at least  twenty  (20) days prior to the record date
for determining holders of the Common Shares for purposes of such action, and in
the case of any such other  action,  at least twenty (20) days prior to the date
of the taking of such proposed  action or the date of  participation  therein by
the holders of the Common Shares, whichever shall be the earlier.

          (b) Notwithstanding  anything in this Agreement to the contrary, prior
to the  Distribution  Date, a filing by the Corporation  with the Securities and
Exchange  Commission  shall constitute  sufficient  notice to the holders of the
securities  of the  Corporation,  including  the  Rights,  for  purposes of this
Agreement and no other notice need be given to such holders.

          (c) If a Triggering Event shall occur,  then (i) the Corporation shall
as soon as practicable thereafter give to each holder of a Right Certificate, in
accordance  with Section 26 hereof,  a notice of the  occurrence  of such event,
which notice shall  describe  such event and the  consequences  of such event to
holders of Rights under Section  11(a)(ii) or Section 13 hereof, as the case may
be, and (ii) all  references  in the  preceding  paragraph  (a) to Common Shares
shall be deemed  thereafter  to refer  also,  if  appropriate,  to common  share
equivalents, as provided for in Section 11(a)(iii).

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

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

          Section 28. DETERMINATION AND ACTIONS BY THE BOARD OF DIRECTORS OF THE
CORPORATION,  ETC. The Board of  Directors  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, or the Corporation, or as may be
necessary or  advisable  in the  administration  of this  Agreement,  including,
without limitation,  the right and power to (i) interpret the provisions of this
Agreement,  and (ii) make all  determinations  deemed necessary or advisable for
the  administration  of  this  Agreement  (including,   without  limitation,   a
determination  to redeem or not redeem the Rights or to amend the  Agreement and
whether any proposed amendment adversely affects the interests of the holders of
Right Certificates and all determinations  pursuant to Section 7(g) hereof). For
all purposes of this  Agreement,  any calculation of the number of Common Shares
or other securities  outstanding at any particular time,  including for purposes
of determining the particular  percentage of such  outstanding  Common Shares or
any other securities of which any Person is the Beneficial Owner,  shall be made
in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules
and  Regulations  under  the  Exchange  Act as in  effect  on the  date  of this
Agreement.  All such actions,  calculations,  interpretations and determinations
(including,  for purposes of clause (y) below, all omissions with respect to the
foregoing) which are done or made by the Board of Directors in good faith, shall
(x) be final,  conclusive and binding on the Corporation,  the Rights Agent, the
holders of the Right Certificates and all other parties, and (y) not subject the
Board of  Directors to any  liability to the holders of the Right  Certificates.
The  Rights  Agent is  entitled  to always  assume  the  Corporation's  Board of
Directors  acted  in good  faith  and  shall  be fully  protected  and  incur no
liability in reliance thereon.

          Section 29.  SUCCESSORS.  All the  covenants  and  provisions  of this
Agreement by or for the benefit of the  Corporation  or the Rights  Agents shall
bind and  inure  to the  benefit  of their  respective  successors  and  assigns
hereunder.

          Section 30.  BENEFITS  OF THIS  AGREEMENT.  Nothing in this  Agreement
shall  be  construed  to  give to any  person  or  corporation  other  than  the
Corporation,   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 Corporation, the Rights Agent
and  the  registered  holders  of the  Right  Certificates  (and,  prior  to the
Distribution Date, the Common Shares).

          Section  31.  SEVERABILITY.   If  any  term,  provision,  covenant  or
restriction  of this Agreement is held by a court of competent  jurisdiction  or
other authority to be invalid, void or unenforceable, the remainder




<PAGE>



of the terms,  provisions,  covenants and  restrictions  of this Agreement shall
remain in full  force and effect and shall in no way be  affected,  impaired  or
invalidated.

          Section 32.  GOVERNING LAW. This Agreement,  each Right and each Right
Certificate  issued  hereunder  shall be deemed to be a contract  made under the
laws of the State of  Delaware  and for all  purposes  shall be  governed by and
construed in accordance  with the laws of such State  applicable to contracts to
be made and performed entirely within such State;  PROVIDED,  HOWEVER,  that the
rights,  duties and  obligations of the Rights Agent hereunder shall be governed
by the laws of the State of New York,  without  regard to New York choice of law
rules.

          Section 33. COUNTERPARTS. This Agreement may be executed in any number
of counterparts and each of such  counterparts  shall for all purposes be deemed
to be an original,  and all such counterparts shall together  constitute but one
and the same instrument.

          Section 34. DESCRIPTIVE HEADINGS.  Descriptive Headings of the several
Sections of this  Agreement  are  inserted  for  convenience  only and shall not
control or affect the meaning or construction of any of the provisions hereof.

"Rights  Agreement")  between  Overseas  Shipholding  Group,  Inc.,  a  Delaware

Date,  one one-tenth of a fully paid,  nonassessable  share of the Common Stock,
par value $0.01 (the  "Common  Shares"),  of the Company at a purchase  price of

          Upon the  occurrence  of a  Section  11(a)(ii)  Event,  if the  Rights
evidenced by this Right  Certificate are beneficially  owned by (a) an Acquiring
Person or an Associate or Affiliate of an Acquiring Person,  (b) a transferee of
a Acquiring  Person (or any such  Associate or Affiliate  thereof) who becomes a
transferee  after the  Acquiring  Person  becomes  such,  or (c)  under  certain
circumstances  specified in the Rights  Agreement,  a transferee of an Acquiring
Person (or any such  Associate  or  Affiliate  thereof) who becomes a transferee
prior to or  concurrently  with the Acquiring  Person becoming such, such Rights
shall  become null and void  without any further  action,  and no holder  hereof
shall have any rights whatsoever with respect to such Rights,  whether under any
provision of the Rights Agreement or otherwise.

          Under   the   Rights   Agreement,   the   Board  of   Directors   may,
notwithstanding  anything to the contrary in the Rights Agreement or this Rights
Certificate,  take such  reasonable  actions and may establish  such  reasonable
procedures as it may deem desirable in connection with the exercise, exchange or
transfer of Rights in order to reasonably  assure,  in the judgment of the Board
of  Directors,  the  preservation  of the  Company's  status as a United  States
Citizen,  including without limitation restricting the issuance of shares of the
Company  pursuant to or in exchange for the Rights to United States  Citizens or
limiting such issuance to non-United States Citizens to such degree as shall, in
the judgment of the Board of Directors,  reasonably  assure  compliance with the
Minimum U.S. Ownership percentage  established from time to time by the Board of
Directors under the Company's Bylaws.

          This Right  Certificate is subject to all of the terms,  covenants and
restrictions of the Rights  Agreement,  which terms,  covenants and restrictions
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,  which
limitations of rights include the temporary  suspension of the exercisability of
such Rights under the specific circumstances set forth in the Rights Agreement.

          Upon  surrender at the office of the Rights Agent  designated for such
purpose  and  subject  to the  terms  and  conditions  set  forth in the  Rights
Agreement,  any  Rights  Certificate  or  Certificates  may  be  transferred  or
exchanged  for another  Rights  Certificate  or  Certificates  evidencing a like
number of Rights as the Rights Certificate or Certificates surrendered.

          Subject  to the  provisions  of the  Rights  Agreement,  the  Board of
Directors of the Company may, at its option,

               (a) at any time  prior to the  earlier  of (i) the time  that any
          Person becomes an Acquiring  Person 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 (subject to adjustment); or

               (b) at any  time  after  the  time  that any  Person  becomes  an
          Acquiring Person (but before such Person, together with all Affiliates
          and Associates of such Person,  becomes the Beneficial Owner of 50% or
          more of the Common Shares then  outstanding),  exchange all or part of
          the then  outstanding  Rights (other than Rights held by the Acquiring
          Person and certain  related  Persons) for Common Shares at an exchange
          ratio of one Common Share per Right (subject to adjustment).

          No  fractional  Common  Shares will be issued upon the exercise of any
Right or Rights  evidenced  hereby,  but in lieu  thereof a cash payment will be
made, as provided in the Rights  Agreement.  If this Right  Certificate shall be
exercised in part, the holder shall be entitled to receive upon surrender hereof
another Right  Certificate  or  Certificates  for the number of whole Rights not
exercised, or the Rights Agent shall place an appropriate notation on this Right
Certificate with respect to those Rights exercised.

                      SUMMARY OF RIGHTS TO PURCHASE SHARES


          On October 20, 1998,  the Board of  Directors of Overseas  Shipholding
Group,   Inc.  (the   "CORPORATION"  or  the  "COMPANY")   declared  a  dividend
distribution  of one right (a "RIGHT") to purchase  one  one-tenth of a share of
the Common Stock,  $1.00 par value, of the Corporation (the "COMMON SHARES") for
each outstanding share of Common Stock, payable to the stockholders of record on
November 9, 1998 (the "RECORD DATE"). The Board of Directors also authorized and
directed  the  issuance of one Right with  respect to each Common  Share  issued
thereafter  until the  Distribution  Date (as  defined  below)  and,  in certain
circumstances, with respect to Common Shares issued after the Distribution Date.
Except as set forth below, each Right, when it becomes exercisable, entitles the
registered  holder to purchase  from the  Corporation  one one-tenth of a Common
Share at a price of $70 per whole Common Share (the "PURCHASE  PRICE"),  subject
to adjustment. The description and terms of the Rights are set forth in a Rights
Agreement  (the "RIGHTS  AGREEMENT")  between the  Corporation  and  ChaseMellon
Shareholder Services,  L.L.C., as Rights Agent (the "RIGHTS AGENT"), dated as of
October 20, 1998.

          Initially,   the  Rights  will  be   attached   to  all   certificates
representing Common Shares then outstanding,  and no separate Right Certificates
will be  distributed.  The Rights will  separate from the Common Shares upon the
earliest to occur of (i) a person or entity (a "PERSON") or group of  affiliated
or associated Persons (a "GROUP") having acquired beneficial ownership of 10% or
more of the outstanding  Common Shares (except pursuant to a Permitted Offer, as
hereinafter  defined); or (ii) 10 business days (or such later date as the Board
of Directors may determine) following the commencement of, or announcement of an
intention to make, a tender offer or exchange  offer the  consummation  of which
would result in a Person or Group becoming an Acquiring  Person (as  hereinafter
defined) (the earliest of such dates being called the  "DISTRIBUTION  DATE").  A
Person or Group whose  acquisition of Common Shares causes a  Distribution  Date
pursuant to clause (i) above is an "ACQUIRING PERSON." The date that a Person or
Group   becomes  an  Acquiring   Person  is  the  "SHARES   ACQUISITION   DATE."
Notwithstanding the foregoing,  certain stockholders who currently own in excess
of 10% of the  outstanding  Common Shares and their  affiliates,  associates and
permitted  transferees  will not be deemed  to be  Acquiring  Persons  and their
ownership  will not cause a  Distribution  Date unless they  acquire  additional
Common Shares equal to more than 20% of the number of Common Shares owed by them
on the date of the Rights Agreement.  Furthermore,  a Person who acquires Common
Shares  pursuant  to a tender or  exchange  offer  which is for all  outstanding
Common  Shares at a price and on terms which the Board of  Directors  determines
(prior  to  acquisition)  to be  adequate  and  in  the  best  interests  of the
Corporation  and its  stockholders  (other than such Person,  its affiliates and
associates) (a "PERMITTED  OFFER") will not be deemed to be an Acquiring  Person
and such Person's ownership will not constitute a Distribution Date.

          The Rights Agreement  provides that, until the Distribution  Date, the
Rights  will be  transferred  with and only with the  Common  Shares.  Until the
Distribution  Date (or earlier  redemption  or  expiration  of the Rights),  new
Common Share certificates  issued after the Record Date upon the transfer or new
issuance  of Common  Shares  will  contain a notation  incorporating  the Rights
Agreement by reference.  Until the Distribution  Date (or earlier  redemption or
expiration of the Rights),  the surrender for transfer of any  certificates  for
Common Shares outstanding as of the Record Date, even without such notation or a
copy of 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 (and to each initial  record holder of certain  Common Shares
issued after the Distribution  Date), and such separate Right Certificates alone
will evidence the Rights.



                                       B-1

<PAGE>



          THE RIGHTS ARE NOT EXERCISABLE  UNTIL THE DISTRIBUTION  DATE, and will
expire at the close of business on November 9, 2008,  unless earlier redeemed by
the Corporation as described below.

          In the event that any person becomes an Acquiring Person,  each holder
of Rights (other than Rights that have become null and void as described  below)
will thereafter have the right (the "FLIP-IN  RIGHT") to receive,  upon exercise
of such Rights, the number of Common Shares (or, in certain circumstances, other
securities  of the  Corporation)  having  a  value  (immediately  prior  to such
triggering  event)  equal to two  times  the  aggregate  exercise  price of such
Rights. (So that, for example,  if a Person became an Acquiring Person at a time
when the current per share market price of the Company's Common Shares is $20.00
(and prior to any antidilution  adjustment as described below), each holder of a
Right  (other than a Right which has become null and void as  described  herein)
would have the right to receive upon  exercise of the Right seven Common  Shares
upon  payment of an exercise  price of $70.00.)  The Board,  at its option,  may
exchange  each  Right  (other  than  those  that  have  become  null and void as
described below) for one Common Share in lieu of the Flip-In Right,  provided no
Person is the  beneficial  owner of 50% or more of the Common Shares at the time
of such exchange. Notwithstanding the foregoing, following the occurrence of the
event  described  above,  all Rights  that are or (under  certain  circumstances
specified in the Rights  Agreement)  were  beneficially  owned by any  Acquiring
Person or any affiliate or associate thereof or certain transferees thereof will
be null and void.

          Under  the  Rights  Agreement,  the Board of  Directors  may take such
reasonable  actions and may establish such reasonable  procedures as it may deem
desirable in  connection  with the  exercise,  exchange or transfer of Rights in
order to  reasonably  assure,  in the  judgment of the Board of  Directors,  the
preservation  of the  Company's  status as a United  States  citizen  within the
provisions  of  Section  2 of the  Shipping  Act of  1916,  as  amended,  or any
successor statute applicable to the business being conducted by the Company (the
"CITIZENSHIP PROVISIONS"), including without limitation restricting the issuance
of shares of the Company  pursuant  to or in  exchange  for the Rights to United
States citizens or limiting such issuance to non-United  States citizens to such
degree as shall,  in the judgment of the Board of Directors,  reasonably  assure
compliance with the Minimum U.S. Ownership  percentage  established from time to
time by the Board of  Directors  under the  Company's  By-laws to  maintain  the
Company's  status as a United States  citizen.  The provisions of this paragraph
will not, however, prevent the transfer after the Distribution Date of any Right
by a non-United  States  citizen to a United States  citizen,  including for the
purpose of permitting  the exercise of the Right by the United  States  citizen,
provided that any such transfer (or exercise) is consistent with such reasonable
procedures as may be  established by the Board to reasonably  assure  compliance
with the Citizenship Provisions and to otherwise carry out the provisions of the
Rights Agreement.

          In the event that, at any time following the Shares  Acquisition Date,
(i) the  Corporation  is  acquired  in a merger  or other  business  combination
transaction  in  which  the  holders  of all of the  outstanding  Common  Shares
immediately  prior to the consummation of the transaction are not the holders of
all of the surviving  corporation's  voting power,  or (ii) more than 50% of the
Corporation's  assets or earning power is sold or transferred,  then each holder
of Rights (except Rights which  previously  have been voided as set forth above)
shall  thereafter  have the right  (the  "FLIP-OVER  RIGHT")  to  receive,  upon
exercise of such Rights,  common shares of the acquiring  company (or in certain
circumstances,  its  parent)  having a value  equal to two times  the  aggregate
exercise price of the Rights; provided,  however, that the Flip Over Right shall
not apply to any transaction  described in clause (i) if (x) such transaction is
with a Person or Persons  (or a wholly  owned  subsidiary  of any such Person or
Persons) that acquired  Common Shares  pursuant to a Permitted Offer and (y) the
price and form of consideration  offered in such transaction is the same as that
paid to all holders of Common Shares whose shares were purchased pursuant to the
Permitted Offer. The holder of a Right will continue to have the Flip-Over Right
whether or not such holder exercises or surrenders the Flip-In Right.

          The Purchase Price  payable,  and the number of Common Shares or other
securities 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 Common Shares, (ii) upon
the grant to

holders of the Common  Shares of certain  rights or warrants to subscribe for or
purchase Common Shares at a price, or securities  convertible into Common Shares
with a conversion  price,  less than the then current market price of the Common
Shares,  or (iii) upon the  distribution  to  holders  of the  Common  Shares of
evidences of indebtedness or assets (excluding regular quarterly cash dividends)
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
such Purchase  Price.  No  fractional  Common Shares will be issued and, in lieu
thereof,  an  adjustment  in cash will be made based on the market  price of the
Common Shares on the last trading day prior to the date of exercise.

          At any time prior to the earlier to occur of (i) a person  becoming an
Acquiring  Person or (ii) the  expiration  of the Rights,  the  Corporation  may
redeem the Rights in whole,  but not in part,  at a price of $.01 per Right (the
"Redemption  Price"),  which redemption shall be effective at such time, on such
basis and with such  conditions  as the Board of Directors  may establish in its
sole discretion. The Corporation may, at its option, pay the Redemption Price in
Common Shares.

          All of the  provisions  of the Rights  Agreement may be amended by the
Board of Directors prior to the Distribution  Date. After the Distribution Date,
the  provisions of the Rights  Agreement may be amended by the Board 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,  subject  to  certain  limitations,  to shorten or
lengthen any time period under the Rights Agreement.

          Until a Right is exercised,  the holder thereof, as such, will have no
rights as a stockholder of the Corporation,  including,  without limitation, the
right to vote or to receive dividends. While the distribution of the Rights will
not be taxable to stockholders of the Corporation,  stockholders may,  depending
upon the  circumstances,  recognize  taxable  income  should the  Rights  become
exercisable or upon the occurrence of certain events thereafter.
