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

         On February 18, 1998 pursuant to a Preferred  Shares  Rights  Agreement
(the  "Rights  Agreement")  between  Interlink  Computer  Sciences,   Inc.  (the
"Company")  and BANKBOSTON,  N.A.,  as Rights Agent (the "Rights  Agent"),  the
Company's  Board of  Directors  declared a dividend  of one right (a "Right") to
purchase  one  one-thousandth  share of the  Company's  Series  A  Participating
Preferred  Stock  ("Series A Preferred")  for each  outstanding  share of Common
Stock,  $0.001  par value per  share  ("Common  Shares"),  of the  Company.  The
dividend  is payable on March 9, 1998 (the  "Record  Date") to  stockholders  of
record  as of the  close of  business  on that  day.  Each  Right  entitles  the
registered holder to purchase from the Company one  one-thousandth of a share of
Series A  Preferred  at an  exercise  price of $30.00  (the  "Purchase  Price"),
subject to adjustment.

         The following summary of the principal terms of the Rights Agreement is
a general  description  only and is subject to the detailed terms and conditions
of the Rights Agreement. A copy of the Rights Agreement is attached as Exhibit 1
to this Registration Statement and is incorporated herein by reference.

Rights Evidenced by Common Share Certificates

         The Rights will not be exercisable until the Distribution Date (defined
below).  Certificates for the Rights ("Rights Certificates") will not be sent to
stockholders  and the Rights  will  attach to and trade only  together  with the
Common Shares. Accordingly,  Common Share certificates outstanding on the Record
Date will evidence the Rights  related  thereto,  and Common Share  certificates
issued  after the Record Date will contain a notation  incorporating  the Rights
Agreement by reference.  Until the Distribution  Date (or earlier  redemption or
expiration  of the Rights),  the surrender or transfer of any  certificates  for
Common  Shares,  outstanding as of the Record Date,  even without  notation or a
copy of the Summary of Rights being attached  thereto,  will also constitute the
transfer of the Rights  associated  with the Common Shares  represented  by such
certificate.

Distribution Date

         The Rights will separate from the Common  Shares,  Rights  Certificates
will be issued and the Rights will become  exercisable  upon the earlier of: (i)
ten days following the first date of a public  announcement by the Company or an
Acquiring  Person (as defined  below) that an  Acquiring  Person has become such
(the "Shares Acquisition Date") or (ii) ten business days (or such later date as
may be determined by the Board of Directors)  following the  commencement of, or
announcement  of an intention to make,  a tender  offer or exchange  offer,  the
consummation  of which would  result in a person or group  becoming an Acquiring
Person.  The earlier of such dates is referred to as the "Distribution  Date." A
person or group of affiliated or associated  persons that beneficially  owns, or
has the right to acquire beneficial ownership of, 15% or more of the outstanding
Common Shares is referred to as an "Acquiring Person."
                                      -2-
<PAGE>
Issuance of Rights Certificates; Expiration of Rights

         As soon as practicable following the Distribution Date, separate Rights
Certificates  will be mailed to holders of record of the Common Shares as of the
close of business on the Distribution Date and such separate Rights Certificates
alone will evidence the Rights from and after the Distribution  Date. The Rights
will expire on the  earliest  of (i)  February  25, 2008 (the "Final  Expiration
Date") or (ii) redemption or exchange of the Rights as described below.

Initial Exercise of the Rights

         Following the  Distribution  Date,  and until one of the further events
described  below,  holders of the  Rights  will be  entitled  to  receive,  upon
exercise and the payment of the Purchase Price, one one-thousandth of a share of
the Series A Preferred.

Right to Buy Company Common Shares

         Unless  the  Rights are  earlier  redeemed,  in the event that a person
becomes an Acquiring Person (a "Triggering  Event"),  then proper provision will
be made so that each holder of a Right which has not theretofore  been exercised
(other than Rights  beneficially  owned by the Acquiring Person or any affiliate
of the Acquiring Person, which will thereafter be void) will thereafter have the
right to receive, upon exercise, Common Shares having a value equal to two times
the  Purchase  Price.  In the event that the  Company  does not have  sufficient
Common Shares  available  for all Rights to be  exercised,  or the Board decides
that such  action is  necessary  and not  contrary  to the  interests  of Rights
holders, the Company may instead substitute cash, assets or other securities for
the Common Shares for which the Rights would have been exercisable.

Right to Buy Acquiring Company Stock

         Similarly,  unless the Rights are earlier redeemed,  in the event that,
after a  Triggering  Event,  (i) the  Company is  acquired  in a merger or other
business  combination  transaction,  or  (ii)  50%  or  more  of  the  Company's
consolidated assets or earning power are sold (other than in transactions in the
ordinary course of business),  proper provision must be made so that each holder
of a  Right  which  has  not  theretofore  been  exercised  (other  than  Rights
beneficially  owned by the  Acquiring  Person or any  affiliate of the Acquiring
Person,  which  will  thereafter  be void)  will  thereafter  have the  right to
receive, upon exercise, shares of common stock of the acquiring company having a
value equal to two times the Purchase Price.

Exchange Provision

         At any time after a Triggering  Event and prior to the  acquisition  by
any person or entity of  beneficial  ownership  of 50% or more of the  Company's
outstanding  Common  Shares,  the Board of Directors of the Company may exchange
the Rights  (other than Rights owned by the  Acquiring  Person),  in whole or in
part, at an exchange ratio of one Common Share per Right.
                                      -3-
<PAGE>
Redemption

         At any time on or prior to the close of  business on the earlier of (i)
the tenth  (10) day  following  the Shares  Acquisition  Date and (ii) the Final
Expiration Date of the Rights,  the Company may redeem the Rights in whole,  but
not in part, at a price of $0.001 per Right. The Company's  ability to redeem is
limited if a majority of the Company's  board of directors is elected by written
consent until (i) 180 days following such election, or (ii) the Company's annual
meeting of shareholders following such election.

Adjustments to Prevent Dilution

         The Purchase  Price  payable,  the number of Rights,  and the number of
Series A Preferred or Common  Shares or other  securities  or property  issuable
upon  exercise  of the Rights are  subject  to  adjustment  from time to time in
connection with the dilutive issuances by the Company as set forth in the Rights
Agreement.  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.

Cash Paid Instead of Issuing Fractional Shares

         No fractional  portion less than integral multiples of one Common Share
or one  one-thousandth  of a share of Series A  Preferred  will be  issued  upon
exercise of a Right and, in lieu  thereof,  an  adjustment  in cash will be made
based on the market  price of the  security to be so issued on the last  trading
date prior to the date of exercise.

No Stockholders' Rights Prior to Exercise

         Until a Right is exercised,  the holder thereof,  as such, will have no
rights as a stockholder  of the Company  (other than any rights  resulting  from
such holder's ownership of Common Shares),  including,  without limitation,  the
right to vote or to receive dividends.

Amendment of Rights Agreement

         The provisions of the Rights  Agreement may be  supplemented or amended
by the Board of Directors in any manner prior to the  Distribution  Date.  After
such date, the provisions of the Rights Agreement may be amended by the Board in
order to (i) cure any ambiguity,  (ii) cure any defect or  inconsistency,  (iii)
shorten or lengthen  any time period  under the Rights  Agreement,  or (iv) make
changes  which  the  Company  may  deem  necessary  and  desirable  which do not
adversely affect the interests of holders of Rights  (excluding the interests of
any Acquiring Person);  provided,  however, that no amendment to adjust the time
period governing redemption under clause (iii) shall be made at such time as the
Rights are not  redeemable.  The  Company's  ability to  supplement or amend the
Rights Agreement is limited if a majority of the Company's board of directors is
elected by written  consent until (i) 180 days following such election,  or (ii)
the Company's annual meeting of shareholders following such election.
                                      -4-
<PAGE>
Rights and Preferences of the Series A Preferred

         Series A Preferred  purchasable upon exercise of the Rights will not be
redeemable.  Each share of Series A Preferred  will be entitled to an  aggregate
dividend of 1,000 times the dividend  declared per Common Share. In the event of
liquidation,  the  holders of the Series A  Preferred  will be entitled to 1,000
times the amount  paid per  Common  Share  plus an amount  equal to accrued  and
unpaid dividends and distributions thereon, whether or not declared, to the date
of such payment.  Each share of Series A Preferred will have 1,000 votes, voting
together  with the Common  Shares.  These  rights  are  protected  by  customary
anti-dilution provisions.

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

Certain Anti-takeover Effects

         The Rights approved by the Company's Board of Directors are designed to
protect  and  maximize  the value of the  outstanding  equity  interests  in the
Company in the event of an  unsolicited  attempt by an acquiror to take over the
Company,  in a  manner  or on  terms  not  approved  by the  Company's  Board of
Directors.  Takeover attempts frequently include coercive tactics to deprive the
Company's  Board of Directors and its  stockholders  of any real  opportunity to
determine the destiny of the Company.  The Rights  dividend has been declared by
the  Company's  Board of Directors in order to deter such  tactics,  including a
gradual  accumulation of shares in the open market of a 15% or greater  position
to be followed by a merger or a partial or two-tier  tender  offer that does not
treat all stockholders  equally.  These tactics unfairly pressure  stockholders,
squeeze  them out of their  investment  without  giving them any real choice and
deprive them of the full value of their shares.

         The Rights are not  intended  to prevent a takeover  of the Company and
will not do so. The Rights may be  redeemed  by the  Company at $0.001 per Right
within ten days after the accumulation of 15% or more of the Company's shares by
a single  acquiror or group.  Accordingly,  the Rights should not interfere with
any merger or business combination approved by the Company's Board of Directors.

         Issuance  of the  Rights  does  not in any  way  weaken  the  financial
strength of the Company or interfere  with its business  plans.  The issuance of
the Rights themselves has no dilutive effect,  will not affect reported earnings
per share, should not be taxable to the Company or to its stockholders, and will
not  change the way in which the  Company's  shares are  presently  traded.  The
Company's  Board of  Directors  believes  that the Rights  represent a sound and
reasonable means of addressing the complex issues of corporate policy created by
the current takeover environment.
                                      -5-
<PAGE>
         However,  the Rights may have the effect of rendering more difficult or
discouraging  an acquisition  of the Company deemed  undesirable by its Board of
Directors.  The Rights may cause substantial  dilution to a person or group that
attempts  to acquire  the  Company on terms or in a manner not  approved  by the
Company's Board of Directors,  except pursuant to an offer  conditioned upon the
negation, purchase or redemption of the Rights.

                                RIGHTS AGREEMENT

         Agreement,  dated as of February 25, 1998,  between INTERLINK  COMPUTER
SCIENCES, INC., a Delaware corporation, (the "Company") and BANKBOSTON, N.A., a
national banking association (the "Rights Agent").

         On February  18, 1998 (the "Rights  Dividend  Declaration  Date"),  the
Board of  Directors  of the Company  authorized  and  declared a dividend of one
Preferred Share Purchase Right (a "Right") for each Common Share (as hereinafter
defined) of the Company  outstanding as of the Close of Business (as hereinafter
defined) on March 9, 1998 (the "Record Date"), each Right representing the right
to purchase one  one-thousandth  of a share of Series A Participating  Preferred
Stock  (as such  number  may be  adjusted  pursuant  to the  provisions  of this
Agreement),  having the rights, preferences and privileges set forth in the form
of Certificate of Designations of Rights, Preferences and Privileges of Series A
Participating  Preferred  Stock attached hereto as Exhibit A, upon the terms and
subject to the conditions herein set forth, and further  authorized and directed
the  issuance  of one Right (as such  number  may be  adjusted  pursuant  to the
provisions  of this  Agreement)  with  respect to each  Common  Share that shall
become  outstanding  between the Record Date and the earlier of the Distribution
Date and the Expiration  Date (as such terms are  hereinafter  defined),  and in
certain circumstances after the Distribution Date.

         NOW,  THEREFORE,  in  consideration  of the  promises  and  the  mutual
agreements herein set forth, the parties hereby agree as follows:

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

                  (a)  "Acquiring  Person"  shall  mean any Person who or which,
together  with  all  Affiliates  and  Associates  of such  Person,  shall be the
Beneficial Owner of 15% or more of the Common Shares then outstanding, but shall
not include the Company,  any Subsidiary of the Company or any employee  benefit
plan of the Company or of any  Subsidiary of the Company,  or any entity holding
Common Shares for or pursuant to the terms of any such plan. Notwithstanding the
foregoing,  no Person shall be deemed to be an Acquiring Person as the result of
an acquisition of Common Shares by the Company which,  by reducing the number of
shares  outstanding,  increases the proportionate  number of shares beneficially
owned by such  Person to 15% or more of the Common  Shares of the  Company  then
outstanding;  provided,  however,  that if a Person shall become the  Beneficial
Owner of 15% or more of the Common  Shares of the Company  then  outstanding  by
reason of share  purchases by the Company and shall,  after such share purchases
by the Company,  become the Beneficial Owner of any additional  Common Shares of
the Company (other than pursuant to a dividend or  distribution  paid or made by
the Company on the  outstanding  Common Shares in Common Shares or pursuant to a
split or subdivision of the outstanding  Common Shares),  then such Person shall
be deemed to be an Acquiring Person unless upon becoming the Beneficial Owner of
such additional  Common Shares of the Company such Person does not  beneficially
own  15%  or  more  of  the  Common  Shares  of the  Company  then  outstanding.
Notwithstanding  the  foregoing,   (i)  if  the  Company's  Board  of  Directors
determines in good faith that a
                                       1
<PAGE>
Person who would otherwise be an "Acquiring  Person," as defined pursuant to the
foregoing  provisions  of this  paragraph  (a),  has become  such  inadvertently
(including,  without  limitation,  because (A) such  Person was unaware  that it
beneficially  owned a percentage of the Common Shares that would otherwise cause
such Person to be an  "Acquiring  Person," as defined  pursuant to the foregoing
provisions of this  paragraph (a), or (B) such Person was aware of the extent of
the  Common  Shares it  beneficially  owned but had no actual  knowledge  of the
consequences of such beneficial  ownership under this Agreement) and without any
intention of changing or influencing control of the Company,  and if such Person
divested or divests as promptly as  practicable  a  sufficient  number of Common
Shares so that such Person would no longer be an "Acquiring  Person," as defined
pursuant to the  foregoing  provisions of this  paragraph  (a), then such Person
shall not be  deemed  to be or to have  become  an  "Acquiring  Person"  for any
purposes of this  Agreement;  and (ii) if, as of the date hereof,  any Person is
the  Beneficial  Owner of 15% or more of the  Common  Shares  outstanding,  such
Person shall not be or become an "Acquiring  Person," as defined pursuant to the
foregoing  provisions of this paragraph (a),  unless and until such time as such
Person shall become the Beneficial Owner of additional Common Shares (other than
pursuant  to a  dividend  or  distribution  paid or made by the  Company  on the
outstanding Common Shares in Common Shares or pursuant to a split or subdivision
of the outstanding Common Shares), unless, upon becoming the Beneficial Owner of
such additional  Common Shares,  such Person is not then the Beneficial Owner of
15% or more of the Common Shares then outstanding.

                  (b) "Adjustment  Fraction" shall have the meaning set forth in
Section 11(a)(i) hereof.

                  (c)  "Affiliate"  and  "Associate"  shall have the  respective
meanings  ascribed  to such  terms  in  Rule  12b-2  of the  General  Rules  and

public  offering of  securities),  or upon the  exercise of  conversion  rights,
exchange  rights,  rights  (other than the  Rights),  warrants  or  options,  or
otherwise; provided, however, that a Person shall not be deemed pursuant to this
Section  1(d)(ii)(A) to be the Beneficial Owner of, or to beneficially  own, (1)
securities  tendered pursuant to a tender or exchange offer made by or on behalf
of such  Person or any of such  Person's  Affiliates  or  Associates  until such
tendered  securities  are accepted for purchase or exchange,  or (2)  securities
which a Person or any of such Person's Affiliates or Associates may be deemed to
have the right to acquire
                                       2
<PAGE>
pursuant to any merger or other  acquisition  agreement  between the Company and
such Person (or one or more of its  Affiliates or  Associates) if such agreement
has been  approved by the Board of Directors of the Company prior to there being
an  Acquiring  Person;  or (B) the  right  to vote  pursuant  to any  agreement,
arrangement  or  understanding;  provided,  however,  that a Person shall not be
deemed the Beneficial Owner of, or to beneficially  own, any security under this
Section 1(d)(ii)(B) if the agreement,  arrangement or understanding to vote such
security  (1) arises  solely  from a  revocable  proxy or consent  given to such
Person in response to a public proxy or consent  solicitation  made pursuant to,
and in accordance with, the applicable rules and regulations of the Exchange Act
and (2) is not also then  reportable  on Schedule 13D under the Exchange Act (or
any comparable or successor report); or

indirectly,  by any other Person (or any  Affiliate or Associate  thereof)  with
which such  Person or any of such  Person's  Affiliates  or  Associates  has any
agreement,  arrangement or understanding,  whether or not in writing (other than
customary  agreements  with and between  underwriters  and selling group members
with respect to a bona fide public  offering of  securities)  for the purpose of
acquiring,  holding, voting (except to the extent contemplated by the proviso to
Section  1(d)(ii)(B))  or disposing of any securities of the Company;  provided,
however,  that in no case shall an officer or  director of the Company be deemed
(x) the Beneficial Owner of any securities beneficially owned by another officer
or  director  of the  Company  solely by reason of  actions  undertaken  by such
persons in their  capacity as officers  or  directors  of the Company or (y) the
Beneficial  Owner of  securities  held of record by the trustee of any  employee
benefit plan of the Company or any  Subsidiary of the Company for the benefit of
any employee of the Company or any  Subsidiary  of the  Company,  other than the
officer or director,  by reason of any  influence  that such officer or director
may have over the voting of the securities held in the plan.

of any  Security  on any date  shall be  deemed to be the  average  of the daily

the Security  selected by the Board of Directors of the Company.  If on any such

shares on such date as determined in good faith by the Board of Directors of the
Company  shall be used.  If the Preferred  Shares are not publicly  traded,  the
Current Per Share Market  Price of the  Preferred  Shares shall be  conclusively
deemed  to be the  Current  Per  Share  Market  Price of the  Common  Shares  as
determined  pursuant to this Section 1(j), as appropriately  adjusted to reflect
any stock split, stock dividend or similar transaction  occurring after the date

traded,  Current Per Share  Market  Price shall mean the fair value per share as
determined  in good  faith  by the  Board of  Directors  of the  Company,  whose

of the Company's transfer agent and registrar.  With respect to certificates for
Common Shares  outstanding as of the Record Date, until the  Distribution  Date,
the Rights will be evidenced by such certificates registered in the names of the
holders thereof together with the Summary of Rights. Until the Distribution Date
(or, if  earlier,  the  Expiration  Date),  the  surrender  for  transfer of any
certificate for Common Shares  outstanding on the Record Date, with or without a
copy of the Summary of Rights,  shall also constitute the transfer of the Rights
associated with the Common Shares represented thereby.

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

         THIS  CERTIFICATE  ALSO  EVIDENCES  AND ENTITLES  THE HOLDER  HEREOF TO

         THE RIGHTS AGREEMENT  WITHOUT CHARGE AFTER RECEIPT OF A WRITTEN REQUEST

         NULL AND VOID.

With respect to such  certificates  containing the foregoing  legend,  until the
earlier of (i) the  Distribution  Date or (ii) the  Expiration  Date, the Rights
associated  with the Common Shares  represented  by such  certificates  shall be
evidenced by such certificates alone, and the surrender for transfer of any such
                                       8

certificate shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby.

                  (d) In the event that the Company  purchases  or acquires  any
Common  Shares  after the Record Date but prior to the  Distribution  Date,  any

so that the Company shall not be entitled to exercise any Rights associated with
the Common Shares which are no longer outstanding.

after the Record Date, as of the date of issuance of such Common  Shares) and on
their  face  shall  entitle  the  holders  thereof to  purchase  such  number of
one-thousandths  of a Preferred Share as shall be set forth therein at the price
set forth therein (such  exercise  price per one  one-thousandth  of a Preferred
Share being  hereinafter  referred to as the "Exercise  Price" and the aggregate
Exercise Price of all Preferred Shares issuable upon exercise of one Right being
hereinafter  referred to as the "Total Exercise Price"), but the number and type
of securities purchasable upon the exercise of each Right and the Exercise Price
shall be subject to adjustment as provided herein.

                  (b) Any Rights  Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring
Person or any Associate or Affiliate of an Acquiring  Person,  (ii) a transferee
of an Acquiring  Person (or of any such  Associate or  Affiliate)  who becomes a
transferee  after the Acquiring  Person becomes such or (iii) a transferee of an
Acquiring  Person  (or of  any  such  Associate  or  Affiliate)  who  becomes  a
transferee prior to or concurrently  with the Acquiring Person becoming such and
receives  such  Rights  pursuant  to either (A) a transfer  (whether  or not for
consideration)  from the Acquiring Person to holders of equity interests in such
Acquiring  Person  or to any  Person  with whom such  Acquiring  Person  has any
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights or (B) a transfer  which the Company's  Board of Directors has determined
is part of a plan,  arrangement or understanding  which has as a primary purpose
or effect avoidance of Section 7(e) hereof,  and any Rights  Certificate  issued
pursuant to Section 6 or Section 11 hereof upon transfer, exchange,  replacement
or  adjustment  of any other Rights  Certificate  referred to in this  sentence,
shall contain (to the extent feasible) the following legend:

         THE  RIGHTS   REPRESENTED  BY  THIS  RIGHTS  CERTIFICATE  ARE  OR  WERE
         BENEFICIALLY OWNED BY A PERSON WHO WAS OR BECAME AN
                                       9
<PAGE>
         ACQUIRING  PERSON OR AN AFFILIATE  OR ASSOCIATE OF AN ACQUIRING  PERSON
         (AS SUCH TERMS ARE DEFINED IN THE RIGHTS AGREEMENT).  ACCORDINGLY, THIS
         RIGHTS  CERTIFICATE AND THE RIGHTS  REPRESENTED  HEREBY MAY BECOME NULL
         AND VOID IN THE  CIRCUMSTANCES  SPECIFIED IN SECTION 7(e) OF THE RIGHTS
         AGREEMENT.

         Section 5. Countersignature and Registration

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

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

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

                  (a)  Subject to the  provisions  of Sections  7(e),  14 and 24
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the Expiration Date, any Rights Certificate
or Rights  Certificates may be transferred,  split up, combined or exchanged for
another  Rights  Certificate  or Rights  Certificates,  entitling the registered
holder to purchase a like number of  one-thousandths  of a Preferred  Share (or,
following a Triggering  Event,  other  securities,  cash or other assets, as the
case may be) as the Rights Certificate or Rights  Certificates  surrendered then
entitled such holder to purchase.  Any registered  holder  desiring to transfer,
split up,  combine or exchange  any Rights  Certificate  or Rights  Certificates
shall make such  request in writing  delivered  to the Rights  Agent,  and shall
surrender the Rights Certificate or Rights Certificates to be transferred, split
up, combined or exchanged at the office of the Rights Agent  designated for such
purpose. Neither the Rights Agent nor the Company shall be obligated to take any
action whatsoever with respect to the
                                       10
<PAGE>
transfer of any such surrendered  Rights Certificate until the registered holder
shall  have  completed  and  signed  the  certificate  contained  in the form of
assignment  on the  reverse  side of such  Rights  Certificate  and  shall  have
provided such  additional  evidence of the identity of the Beneficial  Owner (or
former  Beneficial  Owner) or Affiliates  or  Associates  thereof as the Company
shall reasonably request.  Thereupon the Rights Agent shall, subject to Sections
7(e), 14 and 24 hereof, countersign and deliver to the person entitled thereto a
Rights Certificate or Rights Certificates,  as the case may be, as so requested.
The  Company  may  require  payment  of a sum  sufficient  to  cover  any tax or
governmental  charge that may be imposed in connection with any transfer,  split
up, combination or exchange of Rights Certificates.

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

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

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

                  (b) The Exercise Price for each  one-thousandth of a Preferred
Share  issuable  pursuant to the  exercise of a Right shall  initially be thirty
dollars  ($30.00),  shall be subject to adjustment from time to time as provided
in Sections 11 and 13 hereof and shall be payable in lawful  money of the United
States of America in accordance with paragraph (c) below.

                  (c)  Upon  receipt  of  a  Rights   Certificate   representing
exercisable  Rights,  with the  form of  election  to  purchase  duly  executed,
accompanied by payment of the Exercise  Price for the number of  one-thousandths
of a Preferred Share (or, following a Triggering Event,  other securities,  cash
or other assets as the case may be) to be  purchased  and an amount equal to any
applicable  transfer  tax  required  to be paid  by the  holder  of such  Rights
Certificate  in  accordance  with Section  9(e) hereof,  the Rights Agent shall,
subject to Section 20(k) hereof, thereupon promptly (i) (A) requisition from any
transfer agent of the Preferred  Shares (or make available,  if the Rights Agent
is the transfer agent for the Preferred  Shares) a certificate  or  certificates
for the  number  of  one-thousandths  of a  Preferred  Share  (or,  following  a
Triggering Event, other securities,  cash or other assets as the case may be) to
be purchased
                                       11
<PAGE>
and the Company hereby irrevocably  authorizes its transfer agent to comply with
all such  requests or (B) if the Company shall have elected to deposit the total
number of  one-thousandths  of a Preferred  Share (or,  following  a  Triggering
Event, other securities,  cash or other assets as the case may be) issuable upon
exercise of the Rights hereunder with a depositary  agent,  requisition from the
depositary agent depositary receipts representing such number of one-thousandths
of a Preferred Share (or, following a Triggering Event,  other securities,  cash
or other  assets  as the  case may be) as are to be  purchased  (in  which  case
certificates for the Preferred Shares (or,  following a Triggering Event,  other
securities,  cash or  other  assets  as the  case  may be)  represented  by such
receipts shall be deposited by the transfer agent with the depositary agent) and
the Company  hereby  directs the  depositary  agent to comply with such request,
(ii) when  appropriate,  requisition  from the  Company the amount of cash to be
paid in lieu of issuance of  fractional  shares in  accordance  with  Section 14
hereof, (iii) after receipt of such certificates or depositary  receipts,  cause
the same to be delivered to or upon the order of the  registered  holder of such
Rights  Certificate,  registered  in such name or names as may be  designated by
such holder and (iv) when appropriate,  after receipt thereof, deliver such cash
to or upon the order of the registered  holder of such Rights  Certificate.  The
payment of the Exercise Price (as such amount may be reduced (including to zero)
pursuant to Section  11(a)(iii)  hereof) and an amount  equal to any  applicable
transfer  tax  required to be paid by the holder of such Rights  Certificate  in
accordance  with Section 9(e) hereof,  may be made in cash or by certified  bank
check, cashier's check or bank draft payable to the order of the Company. In the
event that the Company is obligated  to issue  securities  of the Company  other
than Preferred  Shares,  pay cash and/or  distribute other property  pursuant to
Section 11(a) hereof,  the Company will make all arrangements  necessary so that
such other securities, cash and/or other property are available for distribution
by the Rights Agent, if and when appropriate.

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

                  (e)   Notwithstanding   anything  in  this  Agreement  to  the
contrary,  from and after the first occurrence of a Triggering Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring  Person,  (ii) a  transferee  of an  Acquiring  Person (or of any such
Associate or  Affiliate)  who becomes a transferee  after the  Acquiring  Person
becomes such (a  "Post-Event  Transferee"),  (iii) a transferee  of an Acquiring
Person (or of any such Associate or Affiliate) who becomes a transferee prior to
or concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer  (whether or not for  consideration)  from the
Acquiring  Person to holders of equity  interests in such Acquiring Person or to
any  Person  with  whom  the  Acquiring  Person  has any  continuing  agreement,
arrangement or understanding  regarding the transferred Rights or (B) a transfer
which  the  Company's  Board  of  Directors  has  determined  is part of a plan,
arrangement  or  understanding  which has as a  primary  purpose  or effect  the
avoidance of this Section 7(e) (a "Pre-Event Transferee") or (iv) any subsequent
transferee  receiving  transferred  Rights  from a  Post-Event  Transferee  or a
Pre-Event  Transferee,  either  directly  or  through  one or more  intermediate
transferees, shall become null and void without any further action and no holder
of such Rights  shall have any rights  whatsoever  with  respect to such Rights,
whether under any provision of this Agreement or otherwise.
                                       12
<PAGE>
The Company shall use all  reasonable  efforts to ensure that the  provisions of
this Section 7(e) and Section 4(b) hereof are complied  with,  but shall have no
liability  to any  holder of  Rights  Certificates  or to any other  Person as a
result of its failure to make any  determinations  with  respect to an Acquiring
Person or any of such Acquiring Person's  Affiliates,  Associates or transferees
hereunder.

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

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

         Section 9. Reservation and Availability of Preferred Shares

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

                  (b) If the Company shall  hereafter  list any of its Preferred
Shares on a national securities  exchange,  then so long as the Preferred Shares
(and, following the occurrence of a Triggering Event, Common Shares and/or other
securities)  issuable and deliverable  upon exercise of the Rights may be listed
on such  exchange,  the Company  shall use its best  efforts to cause,  from and
after such time as the Rights become exercisable (but only to the extent that it
is reasonably likely that the Rights will be exercised), all shares reserved for
such issuance to be listed on such  exchange  upon  official  notice of issuance
upon such exercise.
                                       13
<PAGE>

                  (c) The  Company  shall use its best  efforts to (i) file,  as
soon as practicable  following the earliest date after the first occurrence of a
Triggering Event in which the  consideration to be delivered by the Company upon
exercise of the Rights is described in Section  11(a)(ii) or Section  11(a)(iii)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a registration  statement  under the Securities Act with respect to
the securities  purchasable upon exercise of the Rights on an appropriate  form,
(ii)  cause  such  registration   statement  to  become  effective  as  soon  as
practicable  after such filing and (iii) cause such  registration  statement  to
remain effective (with a prospectus at all times meeting the requirements of the
Securities  Act) until the earlier of (A) the date as of which the Rights are no
longer  exercisable  for such  securities  and (B) the date of expiration of the
Rights. The Company may temporarily  suspend,  for a period not to exceed ninety
(90) days after the date set forth in clause (i) of the first  sentence  of this
Section 9(c), the exercisability of the Rights in order to prepare and file such
registration  statement  and  permit  it to  become  effective.  Upon  any  such
suspension,  the Company shall issue a public announcement  stating,  and notify
the Rights Agent,  that the  exercisability  of the Rights has been  temporarily
suspended, as well as a public announcement and notification to the Rights Agent
at such time as the  suspension  is no longer in effect.  The Company  will also
take such action as may be appropriate  under, or to ensure compliance with, the
securities  or "blue  sky" laws of the  various  states in  connection  with the
exercisability of the Rights. Notwithstanding any provision of this Agreement to
the contrary,  the Rights shall not be exercisable in any  jurisdiction,  unless
the requisite qualification in such jurisdiction shall have been obtained, or an
exemption therefrom shall be available,  and until a registration  statement has
been declared effective.

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

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

         Section 10. Record Date.  Each Person in whose name any certificate for
a number of  one-thousandths  of a Preferred  Share (or other  securities of the
Company) is issued upon the  exercise of Rights shall for all purposes be deemed
to have become the holder of record of Preferred Shares (or other
                                       14
<PAGE>
securities of the Company) represented thereby on, and such certificate shall be
dated,  the date upon which the Rights  Certificate  evidencing  such Rights was
duly  surrendered  and payment of the Total Exercise Price with respect to which
the Rights have been  exercised (and any  applicable  transfer  taxes) was made;
provided, however, that if the date of such surrender and payment is a date upon
which the transfer books of the Company are closed,  such Person shall be deemed
to have become the record holder of such shares on, and such  certificate  shall
be dated,  the next  succeeding  Business Day on which the transfer books of the
Company are open.  Prior to the exercise of the Rights  evidenced  thereby,  the
holder of a Rights  Certificate  shall not be entitled to any rights of a holder
of Preferred  Shares (or other  securities  of the Company) for which the Rights
shall be  exercisable,  including,  without  limitation,  the right to vote,  to
receive dividends or other  distributions or to exercise any preemptive  rights,
and shall not be  entitled  to  receive  any  notice of any  proceedings  of the
Company, except as provided herein.

         Section 11. Adjustment of Exercise Price, Number of Shares or Number of
Rights.  The  Exercise  Price,  the number and kind of shares or other  property
covered  by each  Right and the  number of Rights  outstanding  are  subject  to
adjustment from time to time as provided in this Section 11.

                  (a)  (i)   Anything  in  this   Agreement   to  the   contrary
notwithstanding,  in the event the  Company  shall at any time after the date of
this  Agreement  (A)  declare a  dividend  on the  Preferred  Shares  payable in
Preferred Shares,  (B) subdivide the outstanding  Preferred Shares,  (C) combine
the  outstanding  Preferred  Shares (by reverse stock split or otherwise) into a
smaller number of Preferred Shares, or (D) issue any shares of its capital stock
in  a   reclassification   of  the   Preferred   Shares   (including   any  such
reclassification  in  connection  with a  consolidation  or  merger in which the
Company is the continuing or surviving  corporation),  then, in each such event,
except as otherwise provided in this Section 11 and Section 7(e) hereof: (1) the
Exercise  Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price  thereafter  shall equal the result obtained
by dividing the  Exercise  Price in effect  immediately  prior to such time by a
fraction (the "Adjustment Fraction"),  the numerator of which shall be the total
number  of  Preferred  Shares  (or  shares  of  capital  stock  issued  in  such
reclassification of the Preferred Shares) outstanding immediately following such
time and the denominator of which shall be the total number of Preferred  Shares
outstanding immediately prior to such time; provided,  however, that in no event
shall the  consideration  to be paid upon the exercise of one Right be less than
the aggregate  par value of the shares of capital stock of the Company  issuable
upon  exercise  of such  Right;  and  (2) the  number  of  one-thousandths  of a
Preferred  Share  (or  share of such  other  capital  stock)  issuable  upon the
exercise of each Right shall equal the number of  one-thousandths of a Preferred
Share (or share of such other capital  stock) as was issuable upon exercise of a
Right  immediately  prior to the  occurrence  of the event  described in clauses
(A)-(D)  of  this  Section  11(a)(i),  multiplied  by the  Adjustment  Fraction;
provided,  however,  that,  no such  adjustment  shall be made  pursuant to this
Section 11(a)(i) to the extent that there shall have simultaneously  occurred an
event  described  in  clause  (A),  (B),  (C)  or (D) of  Section  11(n)  with a
proportionate  adjustment  being made  thereunder.  Each Common Share that shall
become  outstanding  after an adjustment  has been made pursuant to this Section
11(a)(i) shall have associated with it the number of Rights,  exercisable at the
Exercise Price and for the number of  one-thousandths  of a Preferred  Share (or
shares of such other capital stock) as one Common Share has  associated  with it
immediately following the adjustment made pursuant to this Section 11(a)(i).
                                       15
<PAGE>
                           (ii) Subject to Section 24 of this Agreement,  in the
event a Triggering  Event shall have  occurred,  then  promptly  following  such
Triggering  Event each holder of a Right,  except as  provided  in Section  7(e)
hereof, shall thereafter have the right to receive for each Right, upon exercise
thereof  in  accordance  with the terms of this  Agreement  and  payment  of the
Exercise Price in effect  immediately  prior to the occurrence of the Triggering
Event, in lieu of a number of  one-thousandths of a Preferred Share, such number
of  Common  Shares  of the  Company  as  shall  equal  the  result  obtained  by
multiplying the Exercise Price in effect  immediately prior to the occurrence of
the Triggering Event by the number of  one-thousandths  of a Preferred Share for
which  a  Right  was  exercisable  (or  would  have  been   exercisable  if  the
Distribution  Date had occurred)  immediately prior to the first occurrence of a
Triggering  Event,  and  dividing  that  product by 50% of the Current Per Share
Market  Price for  Common  Shares on the date of  occurrence  of the  Triggering
Event;  provided,  however,  that the  Exercise  Price and the  number of Common
Shares of the Company so receivable upon exercise of a Right shall be subject to
further  adjustment as  appropriate  in accordance  with Section 11(e) hereof to
reflect  any events  occurring  in respect of the Common  Shares of the  Company
after the occurrence of the Triggering Event.

                           (iii) In lieu of issuing  Common Shares in accordance
with  Section  11(a)(ii)  hereof,  the Company  may, if the  Company's  Board of
Directors  determines  that such  action is  necessary  or  appropriate  and not
contrary to the  interest of holders of Rights and, in the event that the number
of  Common  Shares  which  are  authorized  by  the  Company's   Certificate  of
Incorporation  but not  outstanding  or reserved for issuance for purposes other
than upon  exercise of the Rights are not  sufficient  to permit the exercise in
full of the Rights,  or if any necessary  regulatory  approval for such issuance
has not been  obtained by the Company,  the Company  shall:  (A)  determine  the
excess of (1) the value of the Common  Shares  issuable  upon the  exercise of a
Right (the  "Current  Value")  over (2) the  Exercise  Price (such  excess,  the
"Spread")  and (B) with  respect  to each  Right,  make  adequate  provision  to
substitute for such Common Shares,  upon exercise of the Rights, (1) cash, (2) a
reduction in the Exercise  Price,  (3) other  equity  securities  of the Company
(including,  without  limitation,  shares or units of  shares  of any  series of
preferred  stock which the  Company's  Board of Directors has deemed to have the
same value as Common  Shares (such shares or units of shares of preferred  stock
are herein called  "Common Stock  Equivalents")),  except to the extent that the
Company has not obtained any necessary  stockholder  or regulatory  approval for
such issuance, (4) debt securities of the Company, except to the extent that the
Company has not obtained any necessary  stockholder  or regulatory  approval for
such issuance, (5) other assets or (6) any combination of the foregoing,  having
an aggregate  value equal to the Current Value,  where such aggregate  value has
been  determined by the Company's  Board of Directors based upon the advice of a
nationally recognized investment banking firm selected by the Company's Board of
Directors;  provided,  however,  if the  Company  shall not have  made  adequate
provision to deliver value  pursuant to clause (B) above within thirty (30) days
following the later of (x) the first  occurrence  of a Triggering  Event and (y)
the date on which the Company's  right of  redemption  pursuant to Section 23(a)
expires  (the  later of (x) and (y) being  referred  to  herein as the  "Section
11(a)(ii) Trigger Date"),  then the Company shall be obligated to deliver,  upon
the  surrender  for  exercise  of a Right and without  requiring  payment of the
Exercise Price,  Common Shares (to the extent  available),  except to the extent
that the  Company has not  obtained  any  necessary  stockholder  or  regulatory
approval for such issuance,  and then, if necessary,  cash,  which shares and/or
cash have an aggregate value equal to the Spread. If
                                       16
<PAGE>
the Company's Board of Directors shall determine in good faith that it is likely
that sufficient  additional  Common Shares could be authorized for issuance upon
exercise in full of the Rights or that any  necessary  regulatory  approval  for
such issuance  will be obtained,  the thirty (30) day period set forth above may
be  extended to the extent  necessary,  but not more than ninety (90) days after
the  Section  11(a)(ii)  Trigger  Date,  in  order  that  the  Company  may seek
stockholder  approval for the  authorization  of such additional  shares or take
action to obtain such regulatory  approval (such period,  as it may be extended,
the "Substitution  Period"). To the extent that the Company determines that some
action  need be taken  pursuant to the first  and/or  second  sentences  of this
Section  11(a)(iii),  the Company  (x) shall  provide,  subject to Section  7(e)
hereof, that such action shall apply uniformly to all outstanding Rights and (y)
may  suspend  the  exercisability  of the  Rights  until the  expiration  of the
Substitution  Period in order to seek any authorization of additional shares, to
take any action to obtain any required  regulatory approval and/or to decide the
appropriate  form of distribution to be made pursuant to such first sentence and
to determine the value thereof. In the event of any such suspension, the Company
shall issue a public announcement  stating that the exercisability of the Rights
has been temporarily suspended, as well as a public announcement at such time as
the suspension is no longer in effect. For purposes of this Section  11(a)(iii),
the value of the Common  Shares  shall be the Current Per Share  Market Price of
the Common  Shares on the Section  11(a)(ii)  Trigger  Date and the value of any
Common  Stock  Equivalent  shall be deemed to have the same  value as the Common
Shares on such date.

                  (b) In case the Company  shall,  at any time after the date of
this  Agreement,  fix a record  date for the  issuance  of  rights,  options  or
warrants to all holders of Preferred Shares entitling such holders (for a period
expiring  within  forty-five  (45)  calendar  days  after such  record  date) to
subscribe for or purchase  Preferred  Shares or Equivalent  Shares or securities
convertible into Preferred Shares or Equivalent  Shares at a price per share (or
having a conversion  price per share, if a security  convertible  into Preferred
Shares or  Equivalent  Shares) less than the then Current Per Share Market Price
of the Preferred Shares or Equivalent  Shares on such record date, then, in each
such case,  the  Exercise  Price to be in effect after such record date shall be
determined by multiplying the Exercise Price in effect immediately prior to such
record  date by a  fraction,  the  numerator  of which  shall be the  number  of
Preferred Shares and Equivalent Shares (if any) outstanding on such record date,
plus the number of Preferred  Shares or Equivalent  Shares,  as the case may be,
which the aggregate  offering  price of the total number of Preferred  Shares or
Equivalent  Shares,  as the case may be, to be  offered  or issued  (and/or  the
aggregate initial  conversion price of the convertible  securities to be offered
or issued) would purchase at such current market price,  and the  denominator of
which shall be the number of  Preferred  Shares and  Equivalent  Shares (if any)
outstanding on such record date, plus the number of additional  Preferred Shares
or  Equivalent  Shares,  as the case may be, to be offered for  subscription  or
purchase  (or  into  which  the  convertible  securities  so to be  offered  are
initially  convertible);   provided,   however,  that  in  no  event  shall  the
consideration  to be paid  upon  the  exercise  of one  Right  be less  than the
aggregate par value of the shares of capital stock of the Company  issuable upon
exercise  of one  Right.  In  case  such  subscription  price  may be  paid in a
consideration part or all of which shall be in a form other than cash, the value
of such  consideration  shall be as  determined  in good faith by the  Company's
Board of Directors,  whose determination shall be described in a statement filed
with the Rights  Agent and shall be binding on the Rights  Agent and the holders
of the Rights.  Preferred Shares and Equivalent  Shares owned by or held for the
account of the Company  shall not be deemed  outstanding  for the purpose of 
                                       17
<PAGE>
any such computation. Such adjustment shall be made successively whenever such a
record date is fixed, and in the event that such rights, options or warrants are
not so issued,  the Exercise  Price shall be adjusted to be the  Exercise  Price
which would then be in effect if such record date had not been fixed.

                  (c) In case the Company  shall,  at any time after the date of
this  Agreement,  fix a record  date for the  making  of a  distribution  to all
holders of the Preferred  Shares or of any class or series of Equivalent  Shares
(including any such  distribution  made in connection  with a  consolidation  or
merger in which the  Company is the  continuing  or  surviving  corporation)  of
evidences  of  indebtedness  or  assets  (other  than a regular  quarterly  cash
dividend,  if any, or a dividend  payable in Preferred  Shares) or  subscription
rights,  options or warrants  (excluding  those  referred to in Section  11(b)),
then,  in each such case,  the Exercise  Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such  record date by a fraction,  the  numerator  of which shall be the
Current Per Share Market Price of a Preferred  Share or an  Equivalent  Share on
such record date,  less the fair market value per Preferred  Share or Equivalent
Share (as  determined  in good faith by the Board of  Directors  of the Company,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent) of the portion of the cash,  assets or evidences of indebtedness so to be
distributed or of such subscription rights or warrants applicable to a Preferred
Share or  Equivalent  Share,  as the case may be, and the  denominator  of which
shall be such Current Per Share Market Price of a Preferred  Share or Equivalent
Share  on such  record  date;  provided,  however,  that in no event  shall  the
consideration  to be paid  upon  the  exercise  of one  Right  be less  than the
aggregate par value of the shares of capital stock of the Company  issuable upon
exercise of one Right. Such adjustments shall be made successively whenever such
a record date is fixed, and in the event that such  distribution is not so made,
the Exercise  Price shall be adjusted to be the Exercise  Price which would have
been in effect if such record date had not been fixed.

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

                  (e) If as a result of an  adjustment  made pursuant to Section
11(a) or 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital  stock  other than  Preferred  Shares,
thereafter  the number of such other shares so  receivable  upon exercise of any
Right  and,  if  required,  the  Exercise  Price  thereof,  shall be  subject to
adjustment  from time to time in a manner and on terms as nearly  equivalent  as
practicable to the provisions with respect to the Preferred  Shares contained in
Sections 11(a),  11(b),  11(c),  11(d),  11(g),  11(h),  11(i), 11(j), 11(k) and
11(l),  and the  provisions  of Sections 7, 9, 10, 13 and 14 with respect to the
Preferred Shares shall apply on like terms to any such other shares.
                                       18
<PAGE>
                  (f) All Rights originally issued by the Company  subsequent to
any adjustment  made to the Exercise Price hereunder shall evidence the right to
purchase,  at the adjusted  Exercise Price, the number of  one-thousandths  of a
Preferred  Share  purchasable  from time to time  hereunder upon exercise of the
Rights, all subject to further adjustment as provided herein.

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

                  (h)  The  Company  may  elect  on or  after  the  date  of any
adjustment of the Exercise Price as a result of the calculations made in Section
11(b) or (c) to adjust the number of Rights,  in substitution for any adjustment
in the number of Preferred Shares purchasable upon the exercise of a Right. Each
of the Rights outstanding after such adjustment of the number of Rights shall be
exercisable for the number of  one-thousandths  of a Preferred Share for which a
Right was exercisable  immediately prior to such adjustment.  Each Right held of
record prior to such adjustment of the number of Rights shall become that number
of  Rights  (calculated  to the  nearest  one  hundred-thousandth)  obtained  by
dividing the Exercise  Price in effect  immediately  prior to  adjustment of the
Exercise Price by the Exercise Price in effect  immediately  after adjustment of
the Exercise Price. The Company shall make a public announcement of its election
to adjust the number of Rights,  indicating the record date for the  adjustment,
and, if known at the time, the amount of the adjustment to be made.  This record
date  may be the  date on  which  the  Exercise  Price  is  adjusted  or any day
thereafter,  but, if the Rights Certificates have been issued, shall be at least
ten (10)  days  later  than  the  date of the  public  announcement.  If  Rights
Certificates  have been  issued,  upon each  adjustment  of the number of Rights
pursuant to this Section 11(h),  the Company shall,  as promptly as practicable,
cause to be  distributed  to  holders of record of Rights  Certificates  on such
record date Rights  Certificates  evidencing,  subject to Section 14 hereof, the
additional  Rights to which such  holders  shall be entitled as a result of such
adjustment,  or, at the option of the Company,  shall cause to be distributed to
such  holders  of  record  in  substitution   and  replacement  for  the  Rights
Certificates  held by such  holders  prior to the date of  adjustment,  and upon
surrender  thereof,  if  required  by  the  Company,   new  Rights  Certificates
evidencing  all the Rights to which such  holders  shall be entitled  after such
adjustment.  Rights Certificates so to be distributed shall be issued,  executed
and countersigned in the manner provided for herein (and may bear, at the option
of the Company,  the adjusted  Exercise  Price) and shall be  registered  in the
names of the  holders  of record  of  Rights  Certificates  on the  record  date
specified in the public announcement.

                  (i)  Irrespective  of any adjustment or change in the Exercise
Price or the  number of  Preferred  Shares  issuable  upon the  exercise  of the
Rights, the Rights  Certificates  theretofore and thereafter issued may continue
to express the Exercise Price per one  one-thousandth  of a Preferred  Share 
                                       19
<PAGE>
and the number of  one-thousandths  of a Preferred Share which were expressed in
the initial Rights Certificates issued hereunder.

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

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

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

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

                  (n) In the event the Company  shall at any time after the date
of this  Agreement (A) declare a dividend on the Common Shares payable in Common
Shares, (B) subdivide the outstanding Common Shares, (C) combine the outstanding
Common  Shares (by reverse stock split or  otherwise)  into a smaller  number of
Common   Shares,   or  (D)  issue  any  shares  of  its   capital   stock  in  a
reclassification  of the Common Shares (including any such  reclassification  in
connection with a consolidation or merger in which the Company is the continuing
or  surviving  corporation),  then,  in each such  event,  except  as  otherwise
provided in this Section  11(a) and Section  7(e) hereof:  (1) each Common 
                                       20
<PAGE>
Share (or shares of capital stock issued in such  reclassification of the Common
Shares) outstanding  immediately  following such time shall have associated with
it the number of Rights as were  associated  with one Common  Share  immediately
prior to the occurrence of the event described in clauses (A)-(D) above; (2) the
Exercise  Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price  thereafter  shall equal the result obtained
by multiplying the Exercise Price in effect  immediately prior to such time by a
fraction,  the  numerator  of which shall be the total  number of Common  Shares
outstanding  immediately  prior to the event described in clauses (A)-(D) above,
and the  denominator  of which  shall  be the  total  number  of  Common  Shares
outstanding  immediately after such event;  provided,  however, that in no event
shall the  consideration  to be paid upon the exercise of one Right be less than
the aggregate  par value of the shares of capital stock of the Company  issuable
upon  exercise  of such  Right;  and  (3) the  number  of  one-thousandths  of a
Preferred  Share (or  shares of such  other  capital  stock)  issuable  upon the
exercise  of each Right  outstanding  after such event shall equal the number of
one-thousandths  of a Preferred Share (or shares of such other capital stock) as
were issuable with respect to one Right  immediately  prior to such event.  Each
Common Share that shall become  outstanding  after an  adjustment  has been made
pursuant  to this  Section  11(n)  shall have  associated  with it the number of
Rights,  exercisable at the Exercise Price and for the number of one-thousandths
of a Preferred Share (or shares of such other capital stock) as one Common Share
has  associated  with it immediately  following the adjustment  made pursuant to
this Section 11(n).  If an event occurs which would require an adjustment  under
both this Section 11(n) and Section  11(a)(ii) hereof,  the adjustment  provided
for in this  Section  11(n) shall be in addition to, and shall be made prior to,
any adjustment required pursuant to Section 11(a)(ii) hereof.

         Section 12. Certificate of Adjusted Exercise Price or Number of Shares.
Whenever an  adjustment  is made as  provided in Sections 11 and 13 hereof,  the
Company shall promptly (a) prepare a certificate  setting forth such  adjustment
and a brief statement of the facts accounting for such adjustment, (b) file with
the Rights Agent and with each transfer agent for the Preferred Shares a copy of
such certificate and (c) mail a brief summary thereof to each holder of a Rights
Certificate in accordance with Section 26 hereof.  Notwithstanding the foregoing
sentence,  the  failure of the Company to make such  certification  or give such
notice shall not affect the validity of such  adjustment  or the force or effect
of the  requirement  for  such  adjustment.  The  Rights  Agent  shall  be fully
protected in relying on any such  certificate  and on any  adjustment  contained
therein and shall not be 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, following a Triggering Event,  directly
or indirectly:

                           (i) the Company shall consolidate with, or merge with
and into, any other Person (other than a wholly-owned  Subsidiary of the Company
in a  transaction  the  principal  purpose  of which is to  change  the state of
incorporation of the Company and which complies with Section 11(m) hereof);
                                       21
<PAGE>
                           (ii) any Person shall  consolidate  with the Company,
or merge with and into the Company and the Company  shall be the  continuing  or
surviving  corporation of such  consolidation  or merger and, in connection with
such merger, all or part of the Common Shares shall be changed into or exchanged
for stock or other securities of any other person (or the Company); or

                           (iii) the Company  shall sell or  otherwise  transfer
(or one or more of its Subsidiaries shall sell or otherwise transfer), in one or
more transactions, assets or earning power aggregating 50% or more of the assets
or earning power of the Company and its  Subsidiaries  (taken as a whole) to any
other  Person or Persons  (other  than the  Company or one or more of its wholly
owned Subsidiaries in one or more transactions,  each of which individually (and
together) complies with Section 11(m) hereof),

                                    then, concurrent with and in each such case,

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

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

                                    (C) the term "Company"  shall  thereafter be
deemed to refer to such Principal Party, it being specifically intended that the
provisions  of  Section  11 hereof  shall  apply  only to such  Principal  Party
following the first occurrence of a Section 13 Event;

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

                                    (E) upon the  subsequent  occurrence  of any
consolidation,  merger,  sale or  transfer  of  assets  or  other  extraordinary
transaction  in respect of such  Principal  Party,  each holder of a Right shall
thereupon  be entitled to receive,  upon  exercise of a Right and payment of the
Total
                                       22
<PAGE>
Exercise Price as provided in this Section  13(a),  such cash,  shares,  rights,
warrants  and other  property  which such  holder  would have been  entitled  to
receive  had such  holder,  at the time of such  transaction,  owned the  Common
Shares  of the  Principal  Party  receivable  upon the  exercise  of such  Right
pursuant to this Section 13(a),  and such Principal  Party shall take such steps
(including,  but not  limited  to,  reservation  of  shares  of stock) as may be
necessary to permit the subsequent exercise of the Rights in accordance with the
terms hereof for such cash, shares, rights, warrants and other property.

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

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

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

                           (ii) in the  case  of any  transaction  described  in
clause (iii) of Section13(a)  hereof, the Person that is the party receiving the
greatest  portion of the assets or earning  power  transferred  pursuant to such
transaction or transactions, or, if more than one Person that is a party to such
transaction or  transactions  receives the same portion of the assets or earning
power so  transferred  and each such  portion  would,  were it not for the other
equal portions,  constitute the greatest  portion of the assets or earning power
so transferred, or if the Person receiving the greatest portion of the assets or
earning power cannot be  determined,  whichever of such Persons is the issuer of
Common Shares having the greatest aggregate market value of shares  outstanding;
provided,  however,  that in any such case  described  in the  foregoing  clause
(b)(i) or (b)(ii),  if the Common  Shares of such Person are not at such time or
have not been continuously  over the preceding  12-month period registered under
Section 12 of the Exchange  Act, then (1) if such Person is a direct or indirect
Subsidiary  of another  Person  the Common  Shares of which are and have been so
registered,  the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of which are and have been so registered,  the term "Principal
Party" shall refer to  whichever of such Persons is the issuer of Common  Shares
having the greatest aggregate market value of shares outstanding, or (3) if such
Person is owned, directly or
                                       23
<PAGE>
indirectly, by a joint venture formed by two or more Persons that are not owned,
directly or  indirectly  by the same Person,  the rules set forth in clauses (1)
and (2)  above  shall  apply to each of the  owners  having an  interest  in the
venture as if the Person owned by the joint  venture was a Subsidiary of both or
all of such joint  venturers,  and the  Principal  Party in each such case shall
bear the  obligations  set  forth in this  Section  13 in the same  ratio as its
interest in such Person bears to the total of such interests.

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

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

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

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

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

                  (d) In case the  "Principal  Party"  for  purposes  of Section
13(b)  hereof  has  provision  in  any of its  authorized  securities  or in its
certificate of incorporation or by-laws or other instrument
                                       24
<PAGE>
governing its corporate  affairs,  which  provision would have the effect of (i)
causing such Principal  Party to issue (other than to holders of Rights pursuant
to  Section  13  hereof),  in  connection  with,  or as a  consequence  of,  the
consummation of a Section 13 Event,  Common Shares or Equivalent  Shares of such
Principal  Party at less than the then Current Per Share Market Price thereof or
securities  exercisable  for, or convertible  into,  Common Shares or Equivalent
Shares of such  Principal  Party at less than such then Current Per Share Market
Price, or (ii) providing for any special  payment,  tax or similar  provision in
connection  with the  issuance  of the  Common  Shares of such  Principal  Party
pursuant  to the  provisions  of Section 13 hereof,  then,  in such  event,  the
Company  hereby  agrees with each holder of Rights that it shall not  consummate
any such  transaction  unless prior thereto the Company and such Principal Party
shall have executed and delivered to the Rights Agent a  supplemental  agreement
providing that the provision in question of such Principal Party shall have been
canceled,  waived  or  amended,  or that  the  authorized  securities  shall  be
redeemed,  so that the  applicable  provision  will have no effect in connection
with or as a consequence of, the consummation of the proposed transaction.

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

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

         Section 14. Fractional Rights and Fractional Shares

                  (a) The Company  shall not be required to issue  fractions  of
Rights or to distribute Rights Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Rights  Certificates  with  regard to which  such  fractional  Rights  would
otherwise  be  issuable,  an amount in cash  equal to the same  fraction  of the
current  market value of a whole Right.  For the purposes of this Section 14(a),
the current  market  value of a whole  Right  shall be the closing  price of the
Rights  for  the  Trading  Day  immediately  prior  to the  date on  which  such
fractional Rights would have been otherwise issuable,  as determined pursuant to
the second sentence of Section 1(j) hereof.

                  (b) The Company  shall not be required to issue  fractions  of
Preferred  Shares  (other than  fractions  that are  integral  multiples  of one
one-thousandth  of a  Preferred  Share)  upon  exercise  of  the  Rights  or  to
distribute  certificates which evidence fractional  Preferred Shares (other than
fractions  that are  integral  multiples  of one  one-thousandth  of a Preferred
Share).  Interests in fractions of Preferred Shares in integral multiples of one
one-thousandth of a Preferred Share may, at the election of the
                                       25
<PAGE>
Company,  be  evidenced  by  depositary  receipts,  pursuant  to an  appropriate
agreement  between the Company and a depositary  selected by it; provided,  that
such agreement shall provide that the holders of such depositary  receipts shall
have all the rights,  privileges  and  preferences to which they are entitled as
beneficial  owners  of the  Preferred  Shares  represented  by  such  depositary
receipts. In lieu of fractional Preferred Shares that are not integral multiples
of one  one-thousandth  of a  Preferred  Share,  the  Company  shall  pay to the
registered holders of Rights  Certificates at the time such Rights are exercised
as herein  provided an amount in cash equal to the same  fraction of the current
market  value of a Preferred  Share.  For purposes of this  Section  14(b),  the
current  market  value of a  Preferred  Share  shall be one  thousand  times the
closing price of a Common Share (as determined  pursuant to the second  sentence
of Section  1(j)  hereof) for the Trading Day  immediately  prior to the date of
such exercise.

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

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

         Section 15.  Rights of Action.  All rights of action in respect of this
Agreement,  excepting  the  rights of action  given to the  Rights  Agent  under
Section 18 hereof, are vested in the respective registered holders of the Rights
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares);  and any registered holder of any Rights  Certificate (or, prior
to the  Distribution  Date,  of the Common  Shares),  without the consent of the
Rights Agent or of the holder of any other Rights  Certificate (or, prior to the
Distribution Date, of the Common Shares),  may, in his or her own behalf and for
his or her own benefit, enforce, and may institute and maintain any suit, action
or  proceeding  against the Company to enforce,  or otherwise act in respect of,
his or her right to exercise the Rights evidenced by such Rights  Certificate in
the manner provided in such Rights  Certificate  and in this Agreement.  Without
limiting the foregoing or any remedies available to the holders of Rights, it is
specifically  acknowledged that the holders of Rights would not have an adequate
remedy at law for any breach of this  Agreement and will be entitled to specific
performance of the obligations  under,  and injunctive  relief against actual or
threatened  violations  of,  the  obligations  of any  Person  subject  to  this
Agreement.

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

                  (a)  prior  to the  Distribution  Date,  the  Rights  will  be
transferable only in connection with the transfer of the Common Shares;
                                       26
<PAGE>
                  (b) after the Distribution  Date, the Rights  Certificates are
transferable  only on the registry  books of the Rights Agent if  surrendered at
the  principal  office  or  offices  of the  Rights  Agent  designated  for such
purposes,  duly endorsed or accompanied  by a proper  instrument of transfer and
with the appropriate forms and certificates fully executed; and

                  (c) subject to Sections 6(a) and 7(f) hereof,  the Company and
the  Rights  Agent  may deem and  treat  the  person  in whose  name the  Rights
Certificate  (or, prior to the Distribution  Date, the associated  Common Shares
certificate)  is  registered  as the  absolute  owner  thereof and of the Rights
evidenced thereby  (notwithstanding any notations of ownership or writing on the
Rights  Certificates or the associated Common Shares  certificate made by anyone
other than the Company or the Rights  Agent) for all  purposes  whatsoever,  and
neither the Company nor the Rights  Agent shall be affected by any notice to the
contrary.

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

         Section 18. Concerning the Rights Agent

                  (a) The Company  agrees to pay to the Rights Agent  reasonable
compensation  for all services  rendered by it hereunder and, from time to time,
on demand of the Rights  Agent,  its  reasonable  expenses  and counsel fees and
other  disbursements  incurred  in the  administration  and  execution  of  this
Agreement and the exercise and performance of its duties hereunder.  The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless  against,
any loss, liability or expense, incurred without gross negligence,  bad faith or
willful misconduct on the part of the Rights Agent, for anything done or omitted
by the Rights Agent in connection with the acceptance and administration of this
Agreement,  including  the costs and expenses of defending  against any claim of
liability  in the  premises.  In no event  will the  Rights  Agent be liable for
special,  indirect,  incidental  or  consequential  loss or  damage  of any kind
whatsoever, even if the Rights Agent has been advised of the possibility of such
loss or damage.

                  (b) The Rights  Agent  shall be  protected  and shall incur no
liability  for, or in respect of any action taken,  suffered or omitted by it in
connection  with,  its  administration  of this  Agreement in reliance  upon any
Rights  Certificate or certificate for the Preferred  Shares or Common Shares or
for other securities of the Company, instrument of assignment or transfer, power
of  attorney,  endorsement,   affidavit,  letter,  notice,  direction,  consent,
certificate,  statement or other paper or document  reasonably believed by it to
be  genuine  and to be  signed,  executed  and,  where  necessary,  verified  or
acknowledged,
                                       27
<PAGE>
by the proper Person or Persons,  or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

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

                  (a)  Any  corporation  into  which  the  Rights  Agent  or any
successor  Rights Agent may be merged or with which it may be  consolidated,  or
any corporation  resulting from any merger or  consolidation to which the Rights
Agent  or any  successor  Rights  Agent  shall be a  party,  or any  corporation
succeeding to the corporate  trust business of the Rights Agent or any successor
Rights Agent,  shall be the  successor to the Rights Agent under this  Agreement
without the  execution  or filing of any paper or any further act on the part of
any of the parties hereto;  provided,  however,  that such corporation  would be
eligible for  appointment  as a successor  Rights Agent under the  provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Agreement,  any of the Rights  Certificates  shall
have been  countersigned but not delivered,  any such successor Rights Agent may
adopt the  countersignature  of the  predecessor  Rights  Agent and deliver such
Rights Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been  countersigned,  any successor Rights Agent may
countersign  such  Rights  Certificates  either  in the name of the  predecessor
Rights Agent or in the name of the successor Rights Agent; and in all such cases
such  Rights  Certificates  shall  have the full  force  provided  in the Rights
Certificates and in this Agreement.

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

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

                  (a) The Rights Agent may consult  with legal  counsel (who may
be legal  counsel for the  Company),  and the written  advice or opinion of such
counsel shall be full and complete  authorization  and  protection to the Rights
Agent as to any action  taken or  omitted by it in good faith and in  accordance
with such written 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 any Acquiring Person and
the determination of Current Per Share Market Price) be proved or established by
the Company  prior to taking or  suffering  any action  hereunder,  such fact or
matter  (unless  other  evidence  in  respect  thereof  be  herein  specifically
prescribed)  may be  deemed  to be  conclusively  proved  and  established  by a
certificate signed by any one of the Chairman of the Board, the Chief
                                       28
<PAGE>
Executive  Officer,  the  President,  any Vice  President,  the Chief  Financial
Officer,  the Secretary or any Assistant  Secretary of the Company and delivered
to the Rights Agent;  and such  certificate  shall be full  authorization to the
Rights  Agent for any  action  taken or  suffered  in good faith by it under the
provisions of this Agreement in reliance upon such certificate.

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

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

                  (e) The Rights Agent shall not be under any  responsibility in
respect of the validity of this  Agreement or the execution and delivery  hereof
(except  the due  execution  hereof by the  Rights  Agent) or in  respect of the
validity or execution  of any Rights  Certificate  (except its  countersignature
thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any change in the  exercisability  of the Rights
or any adjustment in the terms of the Rights  (including  the manner,  method or
amount  thereof)  provided  for  in  Sections  3,  11,  13,  23 or  24,  or  the
ascertaining  of the  existence  of facts that would  require any such change or
adjustment  (except with  respect to the exercise of Rights  evidenced by Rights
Certificates  after  receipt  by the  Rights  Agent of a  certificate  furnished
pursuant to Section 12 describing  such change or  adjustment);  nor shall it by
any act  hereunder  be deemed to make any  representation  or warranty as to the
authorization  or reservation of any Preferred  Shares to be issued  pursuant to
this Agreement or any Rights  Certificate or as to whether any Preferred  Shares
will,  when  issued,   be  validly   authorized  and  issued,   fully  paid  and
nonassessable.

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

                  (g) The Rights  Agent is hereby  authorized  and  directed  to
accept instructions with respect to the performance of its duties hereunder from
any  one  of the  Chairman  of the  Board,  the  Chief  Executive  Officer,  the
President, any Vice President, the Chief Financial Officer, the Secretary or any
Assistant Secretary of the Company,  and to apply to such officers for advice or
instructions in connection  with its duties,  and it shall not be liable for any
action taken or suffered by it in good faith in accordance with  instructions of
any  such  officer  or  for  any  delay  in  acting  while   waiting  for  those
instructions.  Any application by the Rights Agent for written instructions from
the  Company  may, at the option of the Rights  Agent,  set forth in writing any
action  proposed  to be taken or omitted by the Rights  Agent  under this Rights
Agreement  and the date on and/or after which such action shall be taken or such
omission shall be effective. The Rights Agent shall not be liable for any action
taken by, or  omission  of,  the  Rights  Agent in  accordance  with a  proposal
included in any such application on or after
                                       29
<PAGE>
the date specified in such  application  (which date shall not be less than five
(5) Business  Days after the date any officer of the Company  actually  receives
such application,  unless any such officer shall have consented in writing to an
earlier date) unless,  prior to taking any such action (or the effective date in
the  case  of an  omission),  the  Rights  Agent  shall  have  received  written
instructions in response to such  application  specifying the action to be taken
or omitted.

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

                  (i) The  Rights  Agent may  execute  and  exercise  any of the
rights or powers hereby vested in it or perform any duty hereunder either itself
or by or through  its  attorneys  or agents,  and the Rights  Agent shall not be
answerable or  accountable  for any act,  default,  neglect or misconduct of any
such attorneys or agents or for any loss to the Company  resulting from any such
act, default,  neglect or misconduct,  provided reasonable care was exercised in
the selection and continued employment thereof.

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

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

         Section 21. Change of Rights  Agent.  The Rights Agent or any successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon  thirty  (30) days'  notice in writing  mailed to the  Company  and to each
transfer  agent of the  Preferred  Shares and the Common Shares by registered or
certified  mail,  and to the holders of the Rights  Certificates  by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty (30) days'  notice in writing,  mailed to the Rights  Agent or  successor
Rights Agent,  as the case may be, and to each  transfer  agent of the Preferred
Shares and the Common Shares by registered or certified mail, and to the holders
of the Rights Certificates by first-class mail. If the Rights Agent shall resign
or be removed or shall otherwise become  incapable of acting,  the Company shall
appoint a successor to the Rights Agent.  If the Company shall fail to make such
appointment  within a period of thirty  (30) days  after  giving  notice of such
removal  or  after  it has been  notified  in  writing  of such  resignation  or
incapacity by the resigning or incapacitated  Rights Agent or by the holder of a
Rights  Certificate  (who  shall,  with such  notice,  submit  his or her Rights
Certificate  for inspection by the Company),  then the registered  holder of any
                                       30
<PAGE>
Rights  Certificate  may apply to any court of  competent  jurisdiction  for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court,  shall be a  corporation  organized and doing
business  under the laws of the  United  States  or of any  state of the  United
States,  in good  standing,  which is  authorized  under  such laws to  exercise
corporate trust or stockholder  services powers and is subject to supervision or
examination  by  federal  or state  authority  and  which has at the time of its
appointment  as Rights  Agent a combined  capital  and  surplus of at least $100
million. After appointment,  the successor Rights Agent shall be vested with the
same powers,  rights,  duties and  responsibilities as if it had been originally
named as Rights Agent without  further act or deed; but the  predecessor  Rights
Agent shall deliver and transfer to the  successor  Rights Agent any property at
the time held by it  hereunder,  and execute and deliver any further  assurance,
conveyance,  act or deed necessary for the purpose. Not later than the effective
date of any such  appointment,  the Company shall file notice thereof in writing
with the  predecessor  Rights  Agent and each  transfer  agent of the  Preferred
Shares  and the  Common  Shares,  and mail a notice  thereof  in  writing to the
registered  holders  of the  Rights  Certificates.  Failure  to give any  notice
provided  for in this  Section 21,  however,  or any defect  therein,  shall not
affect the  legality  or validity  of the  resignation  or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

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

         Section 23. Redemption

                  (a) The Company  may,  at its option and with the  approval of
the  Board of  Directors,  at any time  prior to the  Close of  Business  on the
earlier of (i) the tenth day following the Shares  Acquisition Date and (ii) the
Final  Expiration  Date,  redeem all but not less than all the then  outstanding
Rights at a  redemption  price of $0.001 per Right,  appropriately  adjusted  to
reflect any stock split, stock 
                                       31
<PAGE>
dividend or similar transaction occurring after the date hereof (such redemption
price being herein referred to as the  "Redemption  Price") and the Company may,
at its option,  pay the  Redemption  Price either in Common Shares (based on the
Current Per Share Market Price thereof at the time of redemption) or cash.  Such
redemption  of the Rights by the Company may be made  effective at such time, on
such  basis  and with such  conditions  as the  Board of  Directors  in its sole
discretion  may  establish.  The date on which the Board of Directors  elects to
make the redemption effective shall be referred to as the "Redemption Date."

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

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

         Section 24. Exchange

                  (a) Subject to applicable  laws,  rules and  regulations,  and
subject to subsection 24(c) below, the Company may, at its option,  by action of
the Board of Directors,  at any time after the occurrence of a Triggering Event,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include  Rights that have become void pursuant to the  provisions of Section
7(e)  hereof)  for Common  Shares at an exchange  ratio of one Common  Share per
Right,  appropriately  adjusted to 
                                       32
<PAGE>
reflect any stock split, stock dividend or similar  transaction  occurring after
the date  hereof  (such  exchange  ratio  being  hereinafter  referred to as the
"Exchange Ratio").  Notwithstanding the foregoing,  the Board of Directors shall
not be  empowered  to effect such  exchange at any time after any Person  (other
than the Company,  any Subsidiary of the Company,  any employee  benefit plan of
the Company or any such  Subsidiary,  or any entity holding Common Shares for or
pursuant  to the  terms of any such  plan),  together  with all  Affiliates  and
Associates of such Person,  becomes the  Beneficial  Owner of 50% or more of the
Common Shares then outstanding.

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

                  (c) In the event that  there  shall not be  sufficient  Common
Shares  issued but not  outstanding  or  authorized  but  unissued to permit any
exchange of Rights as contemplated in accordance with Section 24(a), the Company
shall either take such action as may be necessary to authorize additional Common
Shares for issuance upon exchange of the Rights or alternatively,  at the option
of a majority of the Board of Directors, with respect to each Right (i) pay cash
in an amount equal to the Current  Value (as  hereinafter  defined),  in lieu of
issuing  Common  Shares  in  exchange  therefor,  or (ii)  issue  debt or equity
securities or a combination thereof,  having a value equal to the Current Value,
in lieu of issuing  Common  Shares in exchange  for each such  Right,  where the
value  of  such  securities  shall  be  determined  by a  nationally  recognized
investment banking firm selected by majority vote of the Board of Directors,  or
(iii)  deliver any  combination  of cash,  property,  Common Shares and/or other
securities having a value equal to the Current Value in exchange for each Right.
For  purposes  of this  Section  24(c) only,  the  Current  Value shall mean the
product of the Current Per Share  Market  Price of Common  Shares on the date of
the occurrence of the event described above in subparagraph  (a),  multiplied by
the number of Common Shares for which the Right  otherwise would be exchangeable
if there  were  sufficient  shares  available.  To the extent  that the  Company
determines that some action need be taken pursuant to clauses (i), (ii) or (iii)
of this  Section  24(c),  the Board of  Directors  may  temporarily  suspend the
exercisability of the Rights for a period of up to sixty (60) days following the
date on which the event described in Section 24(a) shall have occurred, in order
to seek any  authorization  of  additional  Common  Shares  and/or to decide the
appropriate  form of distribution to be made pursuant to the above 
                                       33
<PAGE>
provision  and to  determine  the  value  thereof.  In  the  event  of any  such
suspension,  the Company  shall  issue a public  announcement  stating  that the
exercisability of the Rights has been temporarily suspended.

                  (d) The Company  shall not be required to issue  fractions  of
Common Shares or to distribute  certificates  which evidence  fractional  Common
Shares.  In lieu of such  fractional  Common Shares,  there shall be paid to the
registered  holders  of the  Rights  Certificates  with  regard  to  which  such
fractional Common Shares would otherwise be issuable, an amount in cash equal to
the same  fraction  of the  current  market  value of a whole  Common  Share (as
determined pursuant to the second sentence of Section 1(j) hereof).

                  (e) The Company  may, at its option,  by majority  vote of the
Board of  Directors,  at any time  before any  Person  has  become an  Acquiring
Person,  exchange  all or part of the then  outstanding  Rights  for  rights  of
substantially  equivalent value, as determined reasonably and with good faith by
the  Board  of  Directors,  based  upon  the  advice  of one or more  nationally
recognized investment banking firms.

                  (f)  Immediately  upon the  action of the  Board of  Directors
ordering the exchange of any Rights pursuant to subsection 24(e) of this Section
24 and without any further action and without any notice,  the right to exercise
such Rights shall  terminate  and the only right  thereafter of a holder of such
Rights  shall be to receive  that number of rights in  exchange  therefor as has
been determined by the Board of Directors in accordance  with  subsection  24(e)
above.  The Company  shall give public  notice of any such  exchange;  provided,
however,  that the  failure to give,  or any defect in,  such  notice  shall not
affect the  validity of such  exchange.  The Company  shall mail a notice of any
such  exchange to all of the holders of such Rights at their last  addresses  as
they appear upon the registry  books of the transfer agent for the Common Shares
of the Company.  Any notice which is mailed in the manner herein  provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of  exchange  will state the method by which the  exchange of the Rights will be
effected.

         Section 25. Notice of Certain Events

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

                  (b) In case any  Triggering  Event or Section  13 Event  shall
occur,  then,  in any  such  case,  the  Company  shall  as soon as  practicable
thereafter  give to each  holder of a Rights  Certificate,  in  accordance  with
Section 26 hereof, a notice of the occurrence of such event, which shall specify
the event and the  consequences of the event to holders of Rights under Sections
11(a)(ii) and 13 hereof.

                  (a)  Prior  to the  occurrence  of a  Distribution  Date,  the
Company  may  supplement  or amend this  Agreement  in any  respect  without the
approval of any holders of Rights and the Rights Agent shall,  if the Company so
directs, execute such supplement or amendment.  From and after the occurrence of
a  Distribution  Date,  the Company  and the Rights  Agent may from time to time
                                       35
<PAGE>
supplement or amend this Agreement without the approval of any holders of Rights
in order to (i) cure any  ambiguity,  (ii) correct or  supplement  any provision
contained  herein  which  may  be  defective  or  inconsistent  with  any  other
provisions  herein,  (iii) shorten or lengthen any time period hereunder or (iv)
to change or supplement the provisions  hereunder in any manner that the Company
may deem  necessary  or  desirable  and that  shall  not  adversely  affect  the
interests  of the  holders  of  Rights  (other  than an  Acquiring  Person or an
Affiliate or Associate of an Acquiring Person); provided, this Agreement may not
be  supplemented  or  amended  to  lengthen,  pursuant  to clause  (iii) of this
sentence,  (A) a time period relating to when the Rights may be redeemed at such
time as the Rights are not then  redeemable  or (B) any other time period unless
such  lengthening is for the purpose of protecting,  enhancing or clarifying the
rights  of,  and/or  the  benefits  to, the  holders  of Rights  (other  than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person).  Upon the
delivery of a certificate from an appropriate officer of the Company that states
that the proposed  supplement  or amendment is in  compliance  with the terms of
this Section 27, the Rights Agent shall  execute such  supplement  or amendment.
Prior to the Distribution  Date, the interests of the holders of Rights shall be
deemed coincident with the interests of the holders of Common Shares.

                  Without  limiting the  foregoing,  the Company may at any time
prior  to such  time as any  Person  becomes  an  Acquiring  Person  amend  this
Agreement  to lower the  thresholds  set forth in Sections  1(a) and 3(a) to not
less than the greater of (i) the sum of .001% and the largest  percentage of the
outstanding  Common Shares then known by the Company to be beneficially owned by
any Person (other than the Company,  any Subsidiary of the Company, any employee
benefit plan of the Company or of any  Subsidiary of the Company,  or any entity
holding  Common  Shares for or  pursuant to the terms of any such plan) and (ii)
10%.

                  (b)  Notwithstanding  the provisions of Section 27(a),  in the
event that a majority  of the Board of  Directors  of the  Company is elected by
stockholder  action by written  consent,  then until the earlier to occur of (i)
the 180th day  following  the  effectiveness  of such  election or (ii) the next
regular  annual   meeting  of   stockholders   of  the  Company   following  the
effectiveness  of such  election  (including  any  postponement  or  adjournment
thereof),  this Rights  Agreement  shall not be  supplemented  or amended in any
manner  reasonably  likely  to have the  purpose  or effect  of  facilitating  a
Transaction with an Interested Person.

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

         Section 29. Determinations and Actions by the Board of Directors,  etc.
For all  purposes of this  Agreement,  any  calculation  of the number of Common
Shares outstanding at any particular time, including for purposes of determining
the particular  percentage of such outstanding Common Shares of which any Person
is the Beneficial  Owner,  shall be made in accordance with the last sentence of
Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act.
The  Board of  Directors  of the  Company  shall  have the  exclusive  power and
authority to  administer  this  Agreement  and to exercise all rights and powers
specifically  granted to the Board,  or the  Company,  or as may be necessary 
                                       36
<PAGE>
or  advisable  in the  administration  of  this  Agreement,  including,  without
limitation,  the  right  and  power  to (i)  interpret  the  provisions  of this
Agreement and (ii) make all determinations deemed necessary or advisable for the
administration  of this Agreement  (including a  determination  to redeem or not
redeem the Rights or to amend the  Agreement).  All such actions,  calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
in good faith,  shall (x) be final,  conclusive and binding on the Company,  the
Rights Agent,  the holders of the Rights  Certificates and all other parties and
(y) not subject the Board to any liability to the holders of the Rights.

         Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company,  the Rights Agent and
the  registered   holders  of  the  Rights   Certificates  (and,  prior  to  the
Distribution  Date, the Common Shares) any legal or equitable  right,  remedy or
claim  under  this  Agreement;  but  this  Agreement  shall  be for the sole and
exclusive benefit of the Company, the Rights Agent and the registered holders of
the  Rights  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 of the
terms, provisions,  covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected,  impaired or invalidated;
provided,  however,  that  notwithstanding  anything  in this  Agreement  to the
contrary, if any such term,  provision,  covenant or restriction is held by such
court  or  authority  to be  invalid,  void or  unenforceable  and the  Board of
Directors of the Company determines in its good faith judgment that severing the
invalid  language  from this  Agreement  would  adversely  affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be  reinstated  and shall not expire  until the Close of  Business  on the
tenth day following the date of such determination by the Board of Directors.

         Section  32.  Governing  Law.  This  Agreement  and each Right and each
Rights  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.

         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.

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

         Section 3. Dividends and Distributions.

                  (a) Subject to the prior and superior  right of the holders of
any shares of any series of Preferred  Stock  ranking  prior and superior to the
shares of Series A Participating Preferred Stock with respect to dividends,  the
holders of shares of Series A Participating Preferred Stock shall be entitled to
receive  when, as and if declared by the Board of Directors out of funds legally
available for the purpose,  quarterly  dividends payable in cash on the last day
of January,  April, July and October in each year (each such date being referred
to herein as a  "Quarterly  Dividend  Payment  Date"),  commencing  on the first
                                       1
<PAGE>
Quarterly  Dividend Payment Date after the first issuance of a share or fraction
of a share of Series A  Participating  Preferred  Stock,  in an amount per share
(rounded to the  nearest  cent)  equal to 1,000  times the  aggregate  per share
amount of all cash  dividends,  and 1,000 times the  aggregate  per share amount
(payable in kind) of all non-cash dividends or other  distributions other than a
dividend  payable in shares of Common Stock or a subdivision of the  outstanding
shares of Common  Stock (by  reclassification  or  otherwise),  declared  on the
Common Stock since the immediately  preceding  Quarterly  Dividend Payment Date,
or, with respect to the first Quarterly  Dividend  Payment Date, since the first
issuance of any share or fraction of a share of Series A Participating Preferred
Stock.

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

                  (c) Dividends  shall begin to accrue on outstanding  shares of
Series A Participating  Preferred Stock from the Quarterly Dividend Payment Date
next  preceding  the date of  issue of such  shares  of  Series A  Participating
Preferred Stock,  unless the date of issue of such shares is prior to the record
date for the first Quarterly  Dividend  Payment Date, in which case dividends on
such  shares  shall begin to accrue  from the date of issue of such  shares,  or
unless the date of issue is a Quarterly Dividend Payment Date or is a date after
the  record  date  for the  determination  of  holders  of  shares  of  Series A
Participating  Preferred  Stock  entitled  to receive a quarterly  dividend  and
before such  Quarterly  Dividend  Payment  Date,  in either of which events such
dividends  shall  begin to accrue from such  Quarterly  Dividend  Payment  Date.
Accrued but unpaid  dividends  shall not bear  interest.  Dividends  paid on the
shares  of Series A  Participating  Preferred  Stock in an amount  less than the
total  amount of such  dividends  at the time accrued and payable on such shares
shall be allocated pro rata on a  share-by-share  basis among all such shares at
the time  outstanding.  The  Board of  Directors  may fix a record  date for the
determination  of holders of shares of Series A  Participating  Preferred  Stock
entitled to receive  payment of a dividend  or  distribution  declared  thereon,
which  record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

         Section  4.  Voting   Rights.   The  holders  of  shares  of  Series  A
Participating Preferred Stock shall have the following voting rights:

                  (a) Each share of Series A Participating Preferred Stock shall
entitle the holder thereof to 1,000 votes on all matters  submitted to a vote of
the stockholders of the Corporation.

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

                  (c)  Except  as   required   by  law,   holders  of  Series  A
Participating  Preferred  Stock  shall have no special  voting  rights and their
consent  shall not be required  (except to the extent they are  entitled to vote
with  holders of Common  Stock as set forth  herein)  for  taking any  corporate
action.

         Section 5. Certain Restrictions.

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

                  (b)  Whenever  quarterly   dividends  or  other  dividends  or
distributions payable on the Series A Participating  Preferred Stock as provided
in  Section  3 are in  arrears,  thereafter  and until all  accrued  and  unpaid
dividends  and  distributions,  whether or not  declared,  on shares of Series A
Participating  Preferred  Stock  outstanding  shall have been paid in full,  the
Corporation shall not

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

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

                           (iii)  redeem or  purchase or  otherwise  acquire for
consideration shares of any stock ranking on a parity (either as to dividends or
upon  liquidation,  dissolution  or winding up) with the Series A  Participating
Preferred Stock, provided that the Corporation may at any time redeem,  purchase
or otherwise  acquire  shares of any such parity stock in exchange for shares of
any stock of the  Corporation  ranking  junior  (either as to  dividends or upon
dissolution,  liquidation or winding up) to the Series A Participating Preferred
Stock;

                           (iv) purchase or otherwise  acquire for consideration
any shares of Series A  Participating  Preferred  Stock,  or any shares of stock
ranking on a parity with the Series A Participating  Preferred Stock,  except in
accordance  with  a  purchase  offer  made  in  writing  or by  publication  (as
determined  by the Board of  Directors)  to all holders of such shares upon such
terms as the Board of Directors,  after  consideration of the respective  annual
dividend  rates and other  relative  rights and  preferences  of the  respective
series and  classes,  shall  determine  in good  faith  will  result in fair and
equitable treatment among the respective series or classes.

                  (c) The  Corporation  shall not permit any  subsidiary  of the
Corporation  to purchase or otherwise  acquire for  consideration  any shares of
stock of the Corporation  unless the Corporation  could,  under paragraph (a) of
this Section 5,  purchase or  otherwise  acquire such shares at such time and in
such manner.

         Section 6.  Reacquired  Shares.  Any  shares of Series A  Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their  cancellation  become  authorized  but unissued
shares  of  Preferred  Stock  and may be  reissued  as part of a new  series  of
Preferred  Stock to be  created by  resolution  or  resolutions  of the Board of
Directors,  subject to the  conditions  and  restrictions  on issuance set forth
herein and, in the Restated Certificate of Incorporation, as then amended.

         Section  7.   Liquidation,   Dissolution   or  Winding   Up.  Upon  any
liquidation, dissolution or winding up of the Corporation, the holders of shares
of Series A  Participating  Preferred  Stock  shall be  entitled  to  receive an
aggregate  amount  per share  equal to 1,000  times the  aggregate  amount to be
distributed  per share to holders of shares of Common Stock plus an amount equal
to any accrued  and unpaid  dividends  on such shares of Series A  Participating
Preferred Stock.

         Section 8.  Consolidation,  Merger,  etc. In case the Corporation shall
enter into any consolidation,  merger, combination or other transaction in which
the shares of Common  Stock are  exchanged  for or changed  into other  stock or
securities,  cash and/or any other property, then in any such case the shares of
Series A  Participating  Preferred  Stock  shall at the same  time be  similarly
exchanged  or changed in an amount per share equal to 1,000 times the  aggregate
amount of stock,  securities,  cash and/or any other property (payable in kind),
as the case may be,  into  which or for  which  each  share of  Common  Stock is
changed or exchanged.

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

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

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

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