Item 1.  Description of Securities to be Registered.

Introduction

     On May 5, 1999,  the Board of Directors of Florida  Rock  Industries,  Inc.
(the  "Company")  declared a dividend of one preferred  share  purchase right (a
"Right") for each  outstanding  share of common stock, par value $.10 per share,
of the Company (the "Common  Shares").  The dividend is payable on June 11, 1999
(the "Record Date") to the  shareholders of record on that date. The description
and terms of the Rights are set forth in an Agreement (the "Agreement")  between
the Company and First Union National Bank as Rights Agent (the "Rights Agent").

Purchase Price

     Each Right entitles the registered  holder to purchase from the Company one
one-hundredth of a share of Series A Junior Participating Preferred Stock of the
Company, par value $.10 per share (the "Preferred  Shares"),  at a price of $145
per one  one-hundredth of a Preferred Share (the "Purchase  Price"),  subject to
adjustment.

Flip-In

     In the event that any person or group of affiliated  or associated  persons
acquires  beneficial  ownership of 15% or more of the outstanding  Common Shares
other than any person or group of  affiliated  or  associated  persons  who were
beneficial owners, individually or collectively, of 15% or more of the Company's
Common Shares outstanding on May 4, 1999 (an "Acquiring Person"), each holder of
a Right,  other than Rights  beneficially  owned by the Acquiring  Person (which
will  thereafter  be  void),  will  thereafter  have the right to  receive  upon
exercise  that number of Common  Shares  having a market  value of two times the
exercise price of the Right. In lieu of a cash payment, the registered holder of
a Right  Certificate  may  exercise  the Rights  (except as  otherwise  provided
herein)  in whole or in part upon  surrender  of the Right  Certificate  with an
election to exercise such Rights without payment of cash. A holder who elects to
make a cashless exercise will receive the number of Common Shares having a value
equal to the Purchase Price.

Flip-Over

     If the  Company  is  acquired  in a merger  or other  business  combination
transaction or 50% or more of its consolidated  assets or earning power are sold
after a person or group has become an Acquiring  Person,  each holder of a Right
(other than Rights  beneficially owned by Acquiring Person,  which will be void)
will  thereafter have the right to receive that number of shares of

                                       2
<PAGE>

common  stock of the issuer  which at the time of such  transaction  will have a
market  value of two times the  exercise  price of the Right.  In lieu of a cash
payment,  the registered  holder of a Right  Certificate may exercise the Rights
(except as otherwise  provided herein) in whole or in part upon surrender of the
Right  Certificate  with an election to exercise such Rights without  payment of
cash. A holder who elects to make a cashless exercise will receive the number of
shares of common stock of the issuer having a value equal to the Purchase Price.

Distribution Date

     The Distribution Date is the earlier of

     (i) The close of  business  on the tenth  business  day  following a public
announcement  that a person or group of affiliated  or  associated  persons have
acquired  beneficial  ownership of 15% or more of the outstanding Common Shares;
or

     (ii) The close of business on the tenth business day (or such later date as
may be  determined  by action of the Board of Directors  of the Company,  if the
Distribution Date shall have previously occurred) following the commencement of,
or  announcement  of an intention to make, a tender offer or exchange  offer the
consummation  of which would result in the  beneficial  ownership by a person or
group of 15% or more of the outstanding Common Shares.

Transfer and Detachment

     Until the Distribution Date, the Rights will be evidenced,  with respect to
any of the Common Share certificates  outstanding as of the Record Date, by such
Common Share certificate with a copy of this Summary of Rights attached thereto.
Until the Distribution Date (or earlier redemption or expiration of the Rights),
the  Rights  will be  transferred  with and only  with the  Common  Shares,  and
transfer of those certificates will also constitute transfer of these Rights.

     As  soon  as  practicable   following  the  Distribution   Date,   separate
certificates  evidencing  the Rights  ("Right  Certificates")  will be mailed to
holders  of record of the  Common  Shares  as of the  close of  business  on the
Distribution  Date and such separate Right  Certificates  alone will  thereafter
evidence the Rights.

Exercisability

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on September  30, 2009 (the "Final  Expiration  Date"),  unless the Final
Expiration  Date is  extended

                                       3
<PAGE>

or unless the Rights are earlier  redeemed or exchanged by the Company,  in each
case, as described below.

Adjustments

     The Purchase  Price  payable,  and the number of Preferred  Shares or other
securities  or  property  issuable,  upon  exercise of the Rights are subject to
adjustment  from  time  to  time to  prevent  dilution  in the  event  of  stock
dividends,  stock  splits,  reclassifications,  or  certain  distributions  with
respect to the Preferred Shares. The number of outstanding Rights and the number
of one  one-hundredths of a Preferred Share issuable upon exercise of each Right
are also subject to adjustment if, prior to the  Distribution  Date,  there is a
stock  split of the  Common  Shares or a stock  dividend  on the  Common  Shares
payable in Common Shares or subdivisions,  consolidations or combinations of the
Common Shares. With certain exceptions, no adjustment in the Purchase Price will
be required until cumulative adjustments require an adjustment of at least 1% in
such Purchase  Price.  No fractional  Preferred Share will be issued (other than
fractions  which are  integral  multiples  of one  one-hundredth  of a Preferred
Share,  which may, at the  election of the Company,  be evidenced by  depositary
receipts) and, in lieu thereof,  an adjustment in cash will be made based on the
market price of the Preferred Share on the last trading day prior to the date of
exercise.

Preferred Shares

     Preferred  Share  purchasable  upon  exercise  of the  Rights  will  not be
redeemable.  Each Preferred  Share will be entitled to, if declared by the Board
of Directors,  a minimum preferential quarterly dividend payment of $1 per share
but will be entitled to an aggregate dividend of 100 times the dividend declared
per Common  Share.  In the event of  liquidation,  the holders of the  Preferred
Share will be entitled to a minimum preferential liquidation payment of $100 per
share but will be entitled to an aggregate payment of 100 times the payment made
per Common Share. Each Preferred Share will have 100 votes, voting together with
the Common Shares.  Finally, in the event of any merger,  consolidation or other
transaction in which Common Shares are exchanged,  each Preferred  Share will be
entitled to receive 100 times the amount received per Common Share. These rights
are protected by customary antidilution provisions.

     The  value  of  the  one  one-hundredth   interest  in  a  Preferred  Share
purchasable  upon  exercise of each Right  should,  because of the nature of the
Preferred Share dividend,  liquidation and voting rights,  approximate the value
of one Common Share.

                                       4
<PAGE>

Exchange

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

Redemption

     At any time prior to the  Expiration  Date,  the Board of  Directors of the
Company may redeem the Rights in whole,  but not in part, at a price of $.01 per
Right  (the  "Redemption  Price").  The  redemption  of the  Rights  may be made
effective  at such  time on such  basis  with  such  conditions  as the Board of
Directors in its sole discretion may establish.  Immediately upon any redemption
of the Rights,  the right to exercise  the Rights  will  terminate  and the only
right of the holders of Rights will be to receive the Redemption Price.

Amendments

     The Rights  Agreement may be amended by the Company without the approval of
any holders of Right Certificates,  including  amendments which add other events
requiring  adjustment to the Purchase  Price payable and the number of Preferred
Shares or other  securities  issuable  upon the  exercise of the Rights or which
modify  procedures  relating to the  redemption of the Rights,  provided that no
amendment may be made which decreases the stated  Redemption Price or the period
of time  remaining  until the Final  Expirations  Date or which  modifies a time
period  relating  to when the Rights may be  redeemed at such time as the Rights
are not then redeemable.

Rights and Holders

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

Further Information

     A copy of the Agreement is available free of charge from the Company.  This
summary  description  of the  Rights  does not  purport  to be  complete  and is
qualified  in its  entirety  by  reference  to the  Agreement,  which is  hereby
incorporated herein by reference.

                                RIGHTS AGREEMENT

     This RIGHTS AGREEMENT, dated as of May 5, 1999 (this "Agreement"),  is made
and  entered  into by and  between  FLORIDA  ROCK  INDUSTRIES,  INC.,  a Florida
corporation  (the  "Company"),  and FIRST  UNION  NATIONAL  BANK,  (the  "Rights
Agent").

                                    Recitals

     WHEREAS,  on May 5, 1999, the Board of Directors of the Company  authorized
and declared a dividend  distribution  of one right  ("Right") for each share of
Common  Stock,  par value $.10 per  share,  of the  Company  (a "Common  Share")
outstanding  as of the Close of Business  (as  hereinafter  defined) on June 11,
1999  (the  "Record  Date"),  each  Right  initially  representing  the right to
purchase one one-hundredth of a Preferred Share (as hereinafter  defined),  upon
the terms and subject to the conditions herein set forth, and further authorized
and  directed the issuance of one Right with respect to each Common Share issued
or delivered by the Company  (whether  originally  issued or delivered  from the
Company's  treasury)  after  the  Record  Date but prior to the  earlier  of the
Distribution  Date  (as  hereinafter   defined)  and  the  Expiration  Date  (as
hereinafter defined).

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

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

     (a) "Acquiring Person" shall mean any Person (other than the Company or any
Subsidiary of the Company or any employee benefit or stock ownership 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) 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;  provided, however, that a Person
shall not be deemed to have become an Acquiring  Person  solely as a result of a
reduction in the number of Common Shares  outstanding  unless and until (i) such
time  as such  Person  or any  Affiliate  or  Associate  of  such  Person  shall
thereafter  become the Beneficial Owner of any additional  Common Shares,  other
than as a  result  of a stock  dividend,  stock  split  or  similar  transaction
effected  by the  Company  in which all  holders of Common  Shares  are  treated
equally,  or (ii) any other  Person  who is the  Beneficial  Owner of any Common
Shares  shall  thereafter  become an  Affiliate  or  Associate  of such  Person;
provided  further,  however,  that a Person  and such  Person's  Affiliates  and
Associates shall not be deemed to be an Acquiring Person if such Person and such
Person's  Affiliates and Associates were the Beneficial  Owner,  individually or
collectively,  of 15% or more of the Common Shares  outstanding  on May 4, 1999.
Notwithstanding  the  foregoing,  if the Board of Directors  determines  in good
faith that a Person who would  otherwise be an  "Acquiring  Person",  as defined
pursuant to the  foregoing  provisions  of this  paragraph  (a), has become such
inadvertently,  and such Person  divests as promptly as practicable a sufficient
number of Common  Shares so that  such  Person  would no longer be an  Acquiring
Person, as defined

<PAGE>

pursuant to the  foregoing  provisions of this  paragraph  (a), then such Person
shall not be deemed to be an "Acquiring Person" for purposes of this Agreement.

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

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

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

         (ii)  Which  such  Person  or   any  of  such  Person's  Affiliates  or
Associates,  directly  or  indirectly,  has the  right  to vote or  dispose  of,
including  pursuant to any agreement,  arrangement or understanding  (whether or
not in writing); or

        (iii)  Of which any other Person is the Beneficial Owner, if such Person
or any of such Person's Affiliates or Associates has any agreement,  arrangement
or  understanding  (whether or not in writing) with such other Person (or any of
such other  Person's  Affiliates  or  Associates)  with  respect  to  acquiring,
holding,  voting  or  disposing  of any  securities  of the  Company;  provided,
however,  that a Person  shall  not be  deemed  the  Beneficial  Owner of, or to
beneficially  own,  any  security  (A) if such Person has the right to vote such
security pursuant to an agreement,  arrangement or understanding (whether or not
in writing) which (1) arises solely from a revocable  proxy 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 (B) if such  beneficial  ownership  arises
solely as a result of such Person's status as a "clearing agency," as defined in
Section  3(a)(23) of the Exchange  Act; and provided,  further,  that nothing in
this paragraph (c) shall cause a Person engaged in business as an underwriter of
securities to be the Beneficial Owner of, or to beneficially own, any securities
acquired  through such Person's  participation  in good faith in an underwriting
syndicate  until  the  expiration  of 40  calendar  days  after the date of such
acquisition,  or such later date as the Board of  Directors  of the  Company may
determine in any specific case.

     (d)  "Business  Day" shall mean any day other than a Saturday,  Sunday or a
day on which banking  institutions  in the State of Florida (or such other state
in which the

                                       2
<PAGE>

principal  office of the Rights Agent is located) are authorized or obligated by
law or executive order to close.

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

     (f) "Common  Shares" when used with reference to the Company shall mean the
Common Stock, par value $.10 per share, of the Company; provided, however, that,
if the Company is the  continuing  or  surviving  corporation  in a  transaction
described in Section 11(a)(ii) or Section 13(a)(ii) hereof, "Common Shares" when
used with  reference  to the  Company  shall  mean the  capital  stock or equity
security  with the  greatest  aggregate  voting  power of the  Company.  "Common
Shares" when used with reference to any corporation or other legal entity, other
than the Company,  including an Issuer,  shall mean the capital  stock or equity
security with the greatest  aggregate  voting power of such corporation or other
legal entity.

     (g)  "Company"  shall  mean  Florida  Rock  Industries,   Inc.,  a  Florida
corporation.

     (h)  "Distribution  Date"  shall  mean the  earliest  of:  (i) the Close of
Business on the tenth Business Day (or, unless the Distribution  Date shall have
previously  occurred,  such  later  date as may be  specified  by the  Board  of

(other than  Common  Shares  issued upon the  exercise or exchange of any Right)
issued or delivered by the Company (whether  originally issued or delivered from
the  Company's  treasury)  after the Record Date but prior to the earlier of the
Distribution Date and the Expiration Date.  Certificates  evidencing such Common

rule or regulation  made pursuant  thereto or with any rule or regulation of any
stock  exchange or transaction  reporting  system on which the Common Shares may
from time to time be listed or quoted, or to conform to usage:

    This  Certificate  also  evidences  and entitles  the holder  hereof to
    certain Rights as set forth in a Rights Agreement  between Florida Rock
    Industries, Inc. and First Union National Bank, dated as of May 5, 1999
    (the "Rights  Agreement"),  the terms of which are hereby  incorporated
    herein  by  reference  and a copy of which is on file at the  principal
    executive  offices of  Florida  Rock  Industries,  Inc.  Under  certain
    circumstances, as set forth in the Rights Agreement, such Rights may be
    redeemed,  may expire,  may be amended or may be  evidenced by separate
    certificates  and no longer be evidenced by this  Certificate.  Florida
    Rock  Industries,  Inc.  will mail to the holder of this  Certificate a
    copy of the Rights Agreement without charge promptly after receipt of a
    written request therefor.  Under certain  circumstances as set forth in
    the Rights Agreement,  Rights beneficially owned by an Acquiring Person
    or any Affiliate or Associate of an Acquiring Person (as such terms are
    defined in the Rights Agreement) may become null and void.

     (d) As promptly as  practicable  after the  Distribution  Date, the Company
shall prepare and execute,  the Rights Agent shall  countersign  and the Company
shall send or cause to be sent (and the Rights Agent shall, if requested, send),
by first-class,  insured,  postage prepaid mail, to each record holder of Common
Shares as of the Close of Business on the  Distribution  Date, at the address of
such holder shown on the records of the Company, a Right Certificate, evidencing
one Right for each Common Share so held, subject to adjustment.  As of and after
the  Distribution  Date,  the  Rights  shall be  evidenced  solely by such Right
Certificates.

     SECTION 4. Form of Right Certificates. The Right Certificates (and the form
of  election  to purchase  and form of  assignment  to be printed on the reverse
thereof) shall be  substantially  in the form set forth as Exhibit B hereto with
such changes, marks of identification or designation and such legends, summaries
or endorsements  printed thereon as the Company may deem  appropriate and as are
not inconsistent with the provisions of this Agreement, or as may be required to
comply with any  applicable  law or with any rule or  regulation  made  pursuant
thereto or with any rule or  regulation  of any stock  exchange  or  transaction
reporting  system on which the Rights may from time to time be listed or quoted,
or to conform  to usage.  Subject to the  provisions  of Section 22 hereof,  the
Right  Certificates,  whenever  issued,  on their face shall entitle the holders
thereof to

                                       6
<PAGE>

purchase such number of one  one-hundredths of a Preferred Share as shall be set
forth therein at the Purchase Price set forth therein,  but the Purchase  Price,
the number and kind of  securities  issuable upon exercise of each Right and the
number of Rights outstanding shall be subject to adjustment as provided herein.

     SECTION 5. Countersignature and Registration.

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

     (b) Following the  Distribution  Date, the Rights Agent shall keep or cause
to be kept,  at the  principal  office of the Rights Agent  designated  for such
purpose  and at such  other  offices  as may be  required  to  comply  with  any
applicable law or with any rule or regulation made pursuant  thereto or with any
rule or regulation of any stock exchange or any transaction  reporting system on
which  the  Rights  may  from  time to time  be  listed  or  quoted,  books  for
registration and transfer of the Right Certificates issued hereunder. Such books
shall  show the names  and  addresses  of the  respective  holders  of the Right
Certificates,  the number of Rights  evidenced  on its face by each of the Right
Certificates and the date of each of the Right Certificates.

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

     (a) Subject to the  provisions of Sections 7(d) and 14 hereof,  at any time
after the Close of Business on the Distribution Date and prior to the Expiration
Date,  any Right  Certificate  or Right  Certificates  representing  exercisable
Rights may be  transferred,  split up,  combined or exchanged  for another Right
Certificate or Right Certificates, entitling the registered holder to purchase a
like number of one one-hundredths of a Preferred Share (or other securities,  as
the case may be) as the Right Certificate or Right Certificates surrendered then
entitled  such holder (or former  holder in the case of a transfer) to purchase.
Any registered  holder  desiring to transfer,  split up, combine or exchange any
such Right  Certificate  shall make such  request  in writing  delivered  to the
Rights Agent, and

                                       7
<PAGE>

shall surrender the Right  Certificate or Right  Certificates to be transferred,
split up,  combined or  exchanged  at the  principal  office of the Rights Agent
designated for such purpose. Thereupon or as promptly as practicable thereafter,
subject to the  provisions  of Sections  7(d) and 14 hereof,  the Company  shall
prepare,  execute and deliver to the Rights  Agent,  and the Rights  Agent shall
countersign and deliver a Right Certificate or Right  Certificates,  as the case
may be, as so requested.  The Company may require payment of a sum sufficient to
cover any tax or governmental  charge that may be imposed in connection with any
transfer, split up, combination or exchange of Right Certificates.

     (b) Upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory  to them of the loss,  theft,  destruction or mutilation of a Right
Certificate,  and,  in case of  loss,  theft or  destruction,  of  indemnity  or
security  reasonably  satisfactory to them, and reimbursement to the Company and
the  Rights  Agent  of all  reasonable  expenses  incidental  thereto,  and upon
surrender  to the Rights  Agent and  cancellation  of the Right  Certificate  if
mutilated,   the  Company  shall  prepare,  execute  and  deliver  a  new  Right
Certificate  of like  tenor to the  Rights  Agent  and the  Rights  Agent  shall
countersign and deliver such new Right  Certificate to the registered  holder in
lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

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

     (a) The registered  holder of any Right Certificate may exercise the Rights
evidenced  thereby (except as otherwise  provided herein) in whole or in part at
any time after the  Distribution  Date and prior to the  Expiration  Date,  upon
surrender of the Right Certificate, with the form of election to purchase on the
reverse side thereof duly executed, to the Rights Agent at the office or offices
of the Rights Agent designated for such purpose,  together with payment in cash,
in lawful money of the United States of America by certified check or bank draft
payable to the order of the Company,  equal to the sum of (i) the exercise price
for the total  number of  securities  as to which  such  surrendered  Rights are
exercised and (ii) an amount equal to any applicable transfer tax required to be
paid by the holder of such Right  Certificate in accordance  with the provisions
of  Section  9 hereof.  For  purposes  of this  Section  7(a),  the value of any
security  shall be the  current  per share  market  price of thereof  (or of the
security as to which such  security is deemed for purposes of this  Agreement to
be an equivalent),  determined pursuant to the applicable  provisions of Section
11(d)  hereof,  on the Trading Day  immediately  preceding the date of the first
occurrence of a Triggering Event.

     (b) Upon receipt of a Right  Certificate  representing  exercisable  Rights
with the form of election  to  purchase  duly  executed,  accompanied  by either
payment as  described  above or a duly  completed  election to exercise  without
payment of cash,  the Rights  Agent  shall  promptly  (i)  requisition  from any
transfer agent of the Preferred  Shares (or make available,  if the Rights Agent
is  the   transfer   agent)   certificates   representing   the  number  of  one
one-hundredths  of a Preferred  Share to be  purchased  (and the Company  hereby
irrevocably  authorizes  and directs its transfer  agent to comply with all such
requests),  or, if the Company  shall have elected to deposit  Preferred  Shares
issuable  upon  exercise  of  the  Rights  hereunder  with a  depositary  agent,
requisition from the depositary

                                       8
<PAGE>

agent depositary  receipts  representing such number of one  one-hundredths of a
Preferred  Share as are to be  purchased  (and the  Company  hereby  irrevocably
authorizes and directs such depositary  agent to comply with all such requests),
(ii) after receipt of such certificates (or depositary receipts, as the case may
be),  cause  the same to be  delivered  to or upon the  order of the  registered
holder of such  Right  Certificate,  registered  in such name or names as may be
designated by such holder, (iii) when appropriate,  requisition from the Company
or any transfer  agent therefor (or make  available,  if the Rights Agent is the
transfer agent) certificates representing the number of equivalent Common Shares
to be issued in lieu of the  issuance of Common  Shares in  accordance  with the
provisions of Section 11(a)(iii) hereof, (iv) when appropriate, after receipt of
such  certificates,  cause the same to be  delivered to or upon the order of the
registered holder of such Right Certificate, registered in such name or names as
may be designated by such holder,  (v) when  appropriate,  requisition  from the
Company  the  amount of cash to be paid in lieu of the  issuance  of  fractional
shares in accordance  with the provisions of Section 14 hereof or in lieu of the
issuance  of  Common  Shares  in  accordance  with  the  provisions  of  Section
11(a)(iii) hereof, (vi) when appropriate, after receipt, deliver such cash to or
upon the order of the  registered  holder of such Right  Certificate,  and (vii)
when  appropriate,  deliver  any due bill or other  instrument  provided  to the
Rights Agent by the Company for delivery to the registered  holder of such Right
Certificate as provided by Section 11(1) hereof.

     (c) In case the registered  holder of any Right  Certificate shall exercise
less than all the Rights evidenced thereby,  the Company shall prepare,  execute
and deliver a new Right  Certificate  evidencing Rights equivalent to the Rights
remaining  unexercised  and the Rights Agent shall  countersign and deliver such
new Right  Certificate to the registered  holder of such Right Certificate or to
his duly authorized assigns, subject to the provisions of Section 14 hereof.

     (d) 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 any  purported  transfer,  split up,  combination  or exchange of any
Right  Certificate  pursuant  to  Section  6  hereof  or  exercise  of  a  Right
Certificate as set forth in this Section 7 unless the registered  holder of such
Right Certificate shall have (i) completed and signed the certificate  following
the form of assignment or the form of election to purchase,  as applicable,  set
forth  on the  reverse  side  of the  Right  Certificate  surrendered  for  such
transfer,  split up,  combination,  exchange or exercise and (ii)  provided such
additional  evidence  of  the  identity  of  the  Beneficial  Owner  (or  former
Beneficial Owner) or Affiliates or Associates  thereof as the Company shall have
reasonably requested.

     SECTION 8.  Cancellation and Destruction of Right  Certificates.  All Right
Certificates  surrendered  for the  purpose  of  exercise,  transfer,  split up,
combination  or exchange  shall,  if surrendered to the Company or to any of its
stock transfer  agents,  be delivered to the Rights Agent for cancellation or in
cancelled  form, or, if  surrendered to the Rights Agent,  shall be cancelled by
it,  and no Right  Certificates  shall  be  issued  in lieu  thereof  except  as
expressly  permitted by this Agreement.  The Company shall deliver to the Rights
Agent for cancellation and retirement,  and the Rights Agent shall so cancel and
retire,  any other  Right  Certificate  purchased  or  acquired  by the  Company
otherwise than

                                       9
<PAGE>

upon the exercise  thereof.  The Rights Agent shall deliver all cancelled  Right
Certificates  to the Company,  or shall,  at the written request of the Company,
destroy such  cancelled  Right  Certificates,  and in such case shall  deliver a
certificate of destruction thereof to the Company.

     SECTION 9. Company Covenants Concerning  Securities And Rights. The Company
covenants and agrees that:

     (a) So long as the Preferred  Shares (and,  following  the  occurrence of a
Triggering  Event,  Common  Shares  and/or other  securities)  issuable upon the
exercise of the Rights may be listed on a national securities exchange, it shall
endeavor to cause,  from and after such time as the Rights  become  exercisable,
all securities reserved for issuance upon the exercise of Rights to be listed on
such exchange upon official notice of issuance upon such exercise.

     (b) It shall take all such  action as may be  necessary  to ensure that all
Preferred Shares (and,  following the occurrence of a Triggering  Event,  Common
Shares and/or other  securities)  delivered upon exercise of Rights, at the time
of  delivery  of the  certificates  for such  securities,  shall be  (subject to
payment of the Purchase  Price) duly and validly  authorized  and issued,  fully
paid and nonassessable securities.

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

     (d) It shall use its best efforts (i) to file on an  appropriate  form,  as
soon as practicable  following the Distribution  Date, a registration  statement
under the Securities  Act with respect to the securities  issuable upon exercise
of the Rights, (ii) to cause such registration  statement to become effective as
soon as  practicable  after such  filing,  and (iii) to cause such  registration
statement  to remain  effective  (with a  prospectus  at all times  meeting  the
requirements  of the Act)  until  the  earlier  of (A) the date as of which  the
Rights are no longer  exercisable  for such  securities  and (B) the  Expiration
Date. The Company shall 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. The Company may temporarily
suspend,  for a period of time  after  the date set  forth in clause  (i) of the
first sentence of this Section 9(d), the exercisability of the Rights

                                       10
<PAGE>

in order to prepare  and file such  registration  statement  and to permit it to
become  effective.  Upon 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.  In  addition,   if  the  Company  shall  determine  that  a
registration  statement  should be filed under the  Securities  Act or any state
securities  laws following the  Distribution  Date, the Company may  temporarily
suspend the  exercisability  of the Rights in each relevant  jurisdiction  until
such time as a registration  statement has been declared effective and, upon 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.
Notwithstanding anything in this Agreement to the contrary, the Rights shall not
be  exercisable  in  any   jurisdiction   if  the  requisite   registration   or
qualification in such jurisdiction  shall not have been effected or the exercise
of the Rights shall not be permitted under applicable law.

     (e) Notwithstanding  anything in this Agreement to the contrary,  after the
Distribution  Date it shall not, except as permitted by Section 23 or Section 26
hereof,  take (or permit any  Subsidiary to take) any action if at the time such
action is taken it is reasonably  foreseeable that such action will eliminate or
otherwise diminish the benefits intended to be afforded by the Rights.

     (f) In the event that the Company is obligated to issue other securities of
the Company  and/or pay cash pursuant to Sections 11, 13 or 14 hereof,  it shall
make all arrangements  necessary so that such other  securities  and/or cash are
available for distribution by the Rights Agent, if and when appropriate.

     SECTION  10.  Record  Date.  Each  Person  in whose  name  any  certificate
representing Preferred Shares (or Common Shares and/or other securities,  as the
case may be) is issued  upon the  exercise of Rights  shall for all  purposes be
deemed to have  become the holder of record of the  Preferred  Shares (or Common
Shares and/or other securities,  as the case may be) represented thereby on, and
such  certificate  shall be  dated,  the date upon  which the Right  Certificate
evidencing  such Rights was duly  surrendered  and payment of the Purchase Price
(and all applicable  transfer taxes) was made;  provided,  however,  that if the
date of such surrender and payment is a date upon which the Preferred Shares (or
Common Shares and/or other securities, as the case may be) transfer books of the
Company are closed, such Person shall be deemed to have become the record holder
of such securities on, and such certificate  shall be dated, the next succeeding
Business  Day on which the  Preferred  Shares (or  Common  Shares  and/or  other
securities, as the case may be) transfer books of the Company are open. Prior to
the exercise of the Rights evidenced thereby,  the holder of a Right Certificate
shall not be entitled to any rights of a shareholder of the Company with respect
to  securities  for which the Rights shall be  exercisable,  including,  without
limitation, the right to vote, to receive dividends or other distributions or to
exercise any preemptive  rights, and shall not be entitled to receive any notice
of any proceedings of the Company, except as provided herein.

                                       11
<PAGE>

     SECTION 11. Adjustment of Purchase Price,  Number And Kind of Securities or
Number of Rights. The Purchase Price, the number and kind of securities issuable
upon exercise of each Right and the number of Rights  outstanding are subject to
adjustment from time to time as provided in this Section 11.

     (a) (i) In the event that the  Company  shall at any time after the date of
this  Agreement  (A)  declare a  dividend  on the  Preferred  Shares  payable in
Preferred Shares,  (B) subdivide the outstanding  Preferred Shares,  (C) combine
the outstanding  Preferred  Shares into a smaller number of Preferred  Shares or
(D) issue any shares of its capital stock in a reclassification of the Preferred
Shares (including any such  reclassification  in connection with a consolidation
or merger in which the Company is the continuing or surviving corporation),  the
Purchase  Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification,  and/or
the number  and/or  kind of shares of capital  stock  issuable on such date upon
exercise of a Right, shall be proportionately adjusted so that the holder of any
Right exercised after such time shall be entitled to receive upon payment of the
Purchase Price then in effect the aggregate number and kind of shares of capital
stock which, if such Right had been exercised immediately prior to such date and
at a time when the Preferred Shares transfer books of the Company were open, the
holder of such Right would have owned upon such  exercise  and been  entitled to
receive   by   virtue   of   such   dividend,   subdivision,    combination   or
reclassification.  If an event occurs which would  require an  adjustment  under
both this Section  11(a)(i) and Section  11(a)(ii)  hereof or Section 13 hereof,
the  adjustment  provided for in this Section  11(a)(i) shall be in addition to,
and  shall be made  prior  to,  any  adjustment  required  pursuant  to  Section
11(a)(ii) or Section 13 hereof.

         (ii) Subject to the provisions of Section 27 hereof, in the event that:

               (A) any  Acquiring  Person or any  Affiliate  or Associate of any
          Acquiring  Person,  at any  time  after  the  date of this  Agreement,
          directly or indirectly,  shall (1) merge into the Company or otherwise
          combine with the Company and the Company  shall be the  continuing  or
          surviving  corporation of such merger or combination  (other than in a
          transaction  subject  to Section 13  hereof),  (2) merge or  otherwise
          combine  with  any  Subsidiary  of the  Company,  (3)  in one or  more
          transactions  (other than in connection  with the exercise or exchange
          of Rights or the exercise or conversion of securities  exercisable for
          or  convertible  into  shares  of any  class of  capital  stock of the
          Company or any of its Subsidiaries) transfer any assets to the Company
          or any of its  Subsidiaries  in  exchange  (in  whole or in part)  for
          shares  of any class of  capital  stock of the  Company  or any of its
          Subsidiaries  or for securities  exercisable  for or convertible  into
          shares  of any class of  capital  stock of the  Company  or any of its
          Subsidiaries,  or  otherwise  obtain  from the  Company  or any of its
          Subsidiaries, with or without consideration,  any additional shares of
          any class of capital  stock of the Company or any of its  Subsidiaries
          or securities  exercisable for or convertible into shares of any class
          of capital stock of the Company or any of its Subsidiaries (other than
          as part of a pro rata  distribution  to all  holders of such shares of
          any class of

                                       12

          capital stock of the Company,  or any of its Subsidiaries),  (4) sell,
          purchase,  lease, exchange,  mortgage,  pledge,  transfer or otherwise
          dispose (in one or more  transactions),  to, from,  with or of, as the
          case may be, the Company or any of its  Subsidiaries  (other than in a
          transaction   subject  to  Section  13  hereof),   assets,   including
          securities, on terms and conditions less favorable to the Company than
          the Company would be able to obtain in arm's-length  negotiation  with
          an unaffiliated  third party,  (5) receive any  compensation  from the
          Company  or any of  its  Subsidiaries  other  than  compensation  as a
          director or for full-time employment as a regular employee,  in either
          case, at rates in accordance with the Company's (or its Subsidiaries')
          past  practices,  or (6) receive the benefit,  directly or  indirectly
          (except  proportionately  as a shareholder),  of any loans,  advances,
          guarantees,  pledges or other financial  assistance or any tax credits
          or  other  tax  advantage  provided  by  the  Company  or  any  of its
          Subsidiaries; or

               (B) during such time as there is an Acquiring Person, there shall
          be any  reclassification  of securities  (including  any reverse stock
          split),  or   recapitalization  of  the  Company,  or  any  merger  or
          consolidation of the Company with any of its Subsidiaries or any other
          transaction or series of transactions  involving the Company or any of
          its Subsidiaries  (whether or not with or into or otherwise  involving
          an Acquiring Person),  other than a transaction  subject to Section 13
          hereof, which has the effect, directly or indirectly, of increasing by
          more than 1% the proportionate  share of the outstanding shares of any
          class  of  equity  securities  or of  securities  exercisable  for  or
          convertible  into  equity  securities  of  the  Company  or any of its
          Subsidiaries  of  which  an  Acquiring  Person  or  any  Affiliate  or
          Associate of any Acquiring Person, is the Beneficial Owner; or

               (C) any Person  (other than (a) the Company or any  Subsidiary of
          the Company or any  employee  benefit or stock  ownership  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 or (b) a
          Person and such Person's  Affiliates and Associates if such Person and
          such Person's  Affiliates  and Associates  were the Beneficial  Owner,
          individually  or  collectively,  of 15% or more of the  Common  Shares
          outstanding on May 4, 1999) who or which, together with all Affiliates
          and  Associates  of such  Person,  shall at any time after the date of
          this  Agreement,  become  the  Beneficial  Owner of 15% or more of the
          Common Shares then outstanding (other than pursuant to any transaction
          set forth in Section 13(a) hereof);  provided,  however, that a Person
          shall not be deemed to have become the Beneficial Owner of 15% or more
          of the Common Shares then outstanding for the purposes of this Section
          11(a)(ii)(C) solely as a result of a reduction in the number of Common
          Shares  outstanding  unless and until such time as (1) such  Person or
          any Affiliate or Associate of such Person shall thereafter  become the
          Beneficial  Owner of any  additional  Common  Shares  other  than as a
          result  of a  stock  dividend,  stock  split  or  similar  transaction
          effected by

                                       13
<PAGE>

          the Company in which all holders of Common Shares are treated equally,
          or (2) any other  Person  who is the  Beneficial  Owner of any  Common
          Shares  shall  thereafter  become an  Affiliate  or  Associate of such
          Person;

then, and in each such case,  proper provision shall be made so that each holder
of a Right,  except as provided below, shall thereafter have a right to receive,
upon  exercise  thereof in  accordance  with the terms of this  Agreement  at an
exercise price per Right equal to the product of the then-current Purchase Price
multiplied by the number of one  one-hundredths of a Preferred Share for which a
Right was exercisable  immediately prior to the first occurrence of a Triggering
Event, in lieu of Preferred Shares,  such number of Common Shares as shall equal
the result obtained by (x) multiplying  the  then-current  Purchase Price by the
number  of one  one-hundredths  of a  Preferred  Share  for  which a  Right  was
exercisable immediately prior to the first occurrence of a Triggering Event, and
dividing  that  product by (y) 50% of the current per share  market price of the
Common Shares  (determined  pursuant to Section 11(d) hereof) on the date of the
first  occurrence of a Triggering  Event. At any time prior to the  Distribution
Date, the Board of Directors of the Company may declare that in lieu of the cash
payment referred to in the immediately preceding sentence, the registered holder
of a Right  Certificate  may exercise the Rights  evidenced  thereby  (except as
otherwise  provided  herein)  in whole or in part  upon  surrender  of the Right
Certificate  with an election to exercise such Rights without payment of cash on
the reverse side thereof duly completed.  With respect to any Rights as to which
such an election is made,  the holder shall receive a number of Common Shares or
other securities having a value equal to the difference between (i) the value of
the Common Shares or other securities that would have been issuable upon payment
of the cash amount as described above, and (ii) the amount of such cash payment.
Notwithstanding  anything in this Agreement to the contrary,  from and after the
Distribution  Date,  (1) any Rights that are or were  acquired  or  beneficially
owned by any Acquiring  Person (or any Affiliate or Associate of such  Acquiring
Person)  shall be void and any holder of such Rights  shall  thereafter  have no
right to exercise  such Rights  under any  provision of this  Agreement,  (2) no
Right  Certificate  shall be issued  pursuant to this Agreement that  represents
Rights  beneficially  owned by an Acquiring Person or any Affiliate or Associate
thereof,  (3) no Right Certificate shall be issued at any time upon the transfer
of any Rights to an Acquiring Person or any Affiliate or Associate thereof or to
any nominee of such Acquiring Person or Affiliate or Associate thereof,  and (4)
any Right Certificate delivered to the Rights Agent for transfer to an Acquiring
Person or any Affiliate or Associate thereof shall be cancelled.

        (iii)  Upon the occurrence  of a Flip-in  Event,  if there  shall not be
sufficient  Common Shares  authorized but unissued or issued but not outstanding
to permit the  issuance of all the Common  Shares  issuable in  accordance  with
subsection  (ii) hereof upon the exercise of a Right,  the Board of Directors of
the Company shall use its best efforts promptly to authorize and, subject to the
provisions of Section 9(d) hereof, make available for issuance additional Common
Shares or other equity securities of the Company having equivalent voting rights
and an equivalent  value (as  determined in good faith by the Board of Directors
of the Company) to the Common Shares (for  purposes of this Section  11(a)(iii),
"equivalent Common Shares"). In the event that equivalent Common

                                       14
<PAGE>

Shares are so  authorized,  upon the exercise of a Right in accordance  with the
provisions  of Section 7 hereof,  the  registered  holder  shall be  entitled to
receive (A) Common  Shares,  to the extent any are available and (B) a number of
equivalent Common Shares, which the Board of Directors of the Company shall have
determined  in good  faith to have a value  equivalent  to the excess of (x) the
aggregate  current per share market value of all the Common  Shares  issuable in
accordance  with  subsection  (ii)  hereof  upon the  exercise  of a Right  (the
"Exercise  Value") over (y) the aggregate  current per share market value of any
Common Shares available for issuance upon the exercise of such Right;  provided,
however,  that if at any time after 90 calendar days after the first  occurrence
of a  Flip-in  Event,  there  shall  not  be  sufficient  Common  Shares  and/or
equivalent  Common  Shares  available for issuance upon the exercise of a Right,
then the Company shall be obligated to deliver, upon the surrender of such Right
and without  requiring  payment of the  Purchase  Price,  Common  Shares (to the
extent  available),  equivalent Common Shares (to the extent available) and then
cash  (to  the  extent  permitted  by  applicable  law  and  any  agreements  or
instruments to which the Company is a party in effect  immediately  prior to the
first occurrence of any Flip-in Event),  which securities and cash shall have an
aggregate  value  equal to the  excess of (1) the  Exercise  Value  over (2) the
product  of the  then-current  Purchase  Price  multiplied  by the number of one
one-hundredths   of  a  Preferred  Share  for  which  a  Right  was  exercisable
immediately  prior to the first occurrence of a Triggering  Event. To the extent
that any legal or contractual  restrictions  prevent the Company from paying the
full amount of cash  payable in  accordance  with the  foregoing  sentence,  the
Company  shall pay to holders of the Rights as to which such  payments are being
made all  amounts  which are not then  restricted  on a pro rata basis and shall
continue to make  payments on a pro rata basis as funds become  available  until
the full amount due to each such Rights holder has been paid.

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

                                       15
<PAGE>

consideration part or all of which shall be in a form other than cash, the value
of such  consideration  shall be as  determined  in good  faith by the  Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent.  Preferred  Shares owned by or held for the account
of the  Company  shall not be deemed  outstanding  for the  purpose  of any such
computation.  Such adjustment shall be made successively  whenever such a record
date is fixed; and in the event that such rights, options or warrants are not so
issued,  the  Purchase  Price shall be adjusted to be the  Purchase  Price which
would then be in effect if such record date had not been fixed.

     (c) In the event that the Company shall fix a record date for the making of
a  distribution  to  all  holders  of  Preferred  Shares   (including  any  such
distribution  made in  connection  with a  consolidation  or merger in which the
Company  is  the   continuing   or  surviving   corporation)   of  evidences  of
indebtedness,  cash (other than a regular periodic cash dividend), assets, stock
(other than a dividend  payable in  Preferred  Shares) or  subscription  rights,
options or warrants  (excluding those referred to in Section 11(b) hereof),  the
Purchase  Price to be in effect  after such record date shall be  determined  by
multiplying the Purchase Price in effect  immediately  prior to such record date
by a fraction,  the  numerator  of which  shall be the current per share  market
price of the Preferred  Shares (as determined  pursuant to Section 11(d) hereof)
on such record date or, if earlier,  the date on which Preferred Shares begin to
trade on an  ex-dividend or when-issued  basis for such  distribution,  less the
fair market value (as  determined in good faith by the Board of Directors of the
Company,  whose  determination  shall be described in a statement filed with the
Rights Agent) of the portion of the evidences of indebtedness,  cash,  assets or
stock so to be distributed or of such subscription  rights,  options or warrants
applicable to one Preferred  Share,  and the  denominator of which shall be such
current per share market price of the Preferred  Shares.  Such adjustments shall
be made successively whenever such a record date is fixed; and in the event that
such  distribution is not so made, the Purchase Price shall again be adjusted to
be the Purchase  Price which would then be in effect if such record date had not
been fixed.

     (d) (i) For the purpose of any  computation  hereunder,  the  "current  per
share  market  price"  of Common  Shares  on any date  shall be deemed to be the
average of the daily  closing  prices per share of such Common Shares for the 30
consecutive Trading Days immediately prior to such date; provided, however, that
in the event that the current  per share  market  price of the Common  Shares is
determined  during a period  following  the  announcement  by the Issuer of such
Common Shares of (A) a dividend or distribution on such Common Shares payable in
such Common Shares or securities convertible into such Common Shares (other than
the Rights) or (B) any  subdivision,  combination  or  reclassification  of such
Common  Shares,  and  prior to the  expiration  of 30  Trading  Days  after  the
ex-dividend date for such dividend or distribution,  or the record date for such
subdivision,  combination or reclassification,  then, and in each such case, the
current  per share  market  price shall be  appropriately  adjusted to take into
account ex-  dividend  trading or to reflect the current per share  market price
per Common Share  equivalent.  The closing  price for each day shall be the last
sale price,  regular  way, or, in case no such sale takes place on such day, the
average of the  closing  bid and asked  prices,  regular  way, in either case as
reported in the principal consolidated transaction

                                       16
<PAGE>

reporting system with respect to securities listed or admitted to trading on the
NYSE or, if the Common Shares are not listed or admitted to trading on the NYSE,
as reported in the  principal  consolidated  transaction  reporting  system with
respect to securities listed on the principal  national  securities  exchange on
which the  Common  Shares are listed or  admitted  to trading  or, if the Common
Shares  are not  listed  or  admitted  to  trading  on any  national  securities
exchange,  the last quoted  price or, if not so quoted,  the average of the high
bid and low asked prices in the over-the-counter  market, as reported by NYSE or
such other system then in use, or, if on any such date the Common Shares are not
quoted by any such organization, the average of the closing bid and asked prices
as furnished by a professional market maker making a market in the Common Shares
selected by the Board of Directors of the Company.  If the Common Shares are not
publicly  held or not so listed or traded,  or not the subject of available  bid
and asked quotes, "current per share market price" shall mean the fair value per
share as  determined  in good faith by the Board of  Directors  of the  Company,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent.

         (ii)  For  the purpose  of any computation  hereunder, the "current per
share market  price" of the  Preferred  Shares shall be  determined  in the same
manner as set forth above for Common Shares in Section  11(d)(i)  hereof,  other
than the last  sentence  thereof.  If the current per share  market price of the
Preferred Shares cannot be determined in the manner provided above, the "current
per share market price" of the Preferred Shares shall be conclusively  deemed to
be an amount equal to the current per share  market  price of the Common  Shares
multiplied  by 100 (as such  number  may be  appropriately  adjusted  to reflect
events  such as stock  splits,  stock  dividends,  recapitalizations  or similar
transactions  relating  to the Common  Shares  occurring  after the date of this
Agreement).  If neither the Common Shares nor the Preferred  Shares are publicly
held or so listed or traded,  or the subject of available  bid and asked quotes,
"current per share  market  price" of the  Preferred  Shares shall mean the fair
value per share as  determined  in good faith by the Board of  Directors  of the
Company,  whose  determination  shall be described in a statement filed with the
Rights Agent.  For all purposes of this Agreement,  the current per share market
price of one  one-hundredth  of a Preferred  Share shall be equal to the current
per share market price of one Preferred Share divided by 100.

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

                                       17
<PAGE>

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

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

     (h) Unless the Company  shall have  exercised  its  election as provided in
Section 11(i) hereof,  upon each adjustment of the Purchase Price as a result of
the calculations  made in Section 11(b) and Section 11(c) hereof with respect to
a  distribution  of  subscription  rights,  options or  warrants  applicable  to
Preferred Shares, each Right outstanding immediately prior to the making of such
adjustment  shall  thereafter  evidence the right to  purchase,  at the adjusted
Purchase  Price,  that  number  of  one  one-hundredths  of  a  Preferred  Share
(calculated to the nearest  ten-millionth  of a Preferred Share) obtained by (i)
multiplying (x) the number of one  one-hundredths  of a Preferred Share issuable
upon  exercise  of a  Right  immediately  prior  to this  adjustment  by (y) the
Purchase Price in effect  immediately  prior to such  adjustment of the Purchase
Price and (ii) dividing the product so obtained by the Purchase  Price in effect
immediately after such adjustment of the Purchase Price.

     (i) The Company may elect,  on or after the date of any  adjustment  of the
Purchase  Price,  to  adjust  the  number  of  Rights  in  substitution  for any
adjustment in the number of one  one-hundredths  of a Preferred  Share  issuable
upon  the  exercise  of a  Right.  Each of the  Rights  outstanding  after  such
adjustment  of the number of Rights shall be  exercisable  for the number of one
one-hundredths   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 ten-thousandth) obtained by dividing the Purchase
Price in effect  immediately  prior to adjustment  of the Purchase  Price by the
Purchase Price in effect immediately after adjustment of the Purchase Price. The
Company shall make a public announcement of its election to adjust the number of
Rights,  indicating  the record  date for the  adjustment,  and, if known at the
time, the amount of the adjustment to be made.  This record date may be the date
on which the Purchase Price is adjusted or any day thereafter, but, if the Right
Certificates have been issued, shall be at least 10 calendar days later than the
date of the public  announcement.  If Right Certificates have been issued,  upon
each  adjustment  of the number of Rights  pursuant to this Section  11(i),  the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Right Certificates on such record date Right Certificates  evidencing,
subject to the provisions of Section 14

                                       18
<PAGE>

hereof,  the  additional  Rights to which such  holders  shall be  entitled as a
result of such adjustment,  or, at the option of the Company,  shall cause to be
distributed to such holders of record in  substitution  and  replacement for the
Right  Certificates  held by such holders prior to the date of  adjustment,  and
upon  surrender  thereof if  required  by the  Company,  new Right  Certificates
evidencing  all the Rights to which such  holders  shall be entitled  after such
adjustment.  Right  Certificates so to be distributed shall be issued,  executed
and countersigned in the manner provided for herein (and may bear, at the option
of the Company,  the adjusted  Purchase  Price) and shall be  registered  in the
names  of the  holders  of  record  of Right  Certificates  on the  record  date
specified in the public announcement.

     (j)  Irrespective  of any adjustment or change in the Purchase Price or the
number or kind of securities issuable upon the exercise of the Rights, the Right
Certificates  theretofore  and  thereafter  issued may  continue  to express the
Purchase Price and the number and kind of securities which were expressed in the
initial Right Certificate issued hereunder.

     (k) Before  taking any action that would cause an  adjustment  reducing the
Purchase  Price below one  one-hundredth  of the then par value,  if any, of the
Preferred Shares or below the then par value, if any, of any other securities of
the Company  issuable  upon  exercise of the Rights,  the Company shall take any
corporate action which may, in the opinion of its counsel, be necessary in order
that the Company may  validly  and  legally  issue fully paid and  nonassessable
Preferred Shares or such other securities,  as the case may be, at such adjusted
Purchase Price.

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

     (m) Notwithstanding anything in this Agreement to the contrary, the Company
shall be entitled to make such  reductions in the Purchase Price, in addition to
those  adjustments  expressly  required by this Section 11, as and to the extent
that in its good faith  judgment  the Board of  Directors  of the Company  shall
determine to be advisable in order that any (i)  consolidation or subdivision of
the Preferred Shares,  (ii) issuance wholly for cash of Preferred Shares at less
than the current per share market price therefor, (iii) issuance wholly for cash
of Preferred  Shares or securities  which by their terms are convertible into or
exchangeable  for Preferred  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  Shares  shall not be taxable to such
shareholders.

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

     SECTION 12. Certificate of Adjusted Purchase Price or Number of Securities.
Whenever an  adjustment  is made as provided in Section 11 or Section 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 and the Common Shares, a copy of such certificate, and

     (c) If such  adjustment is made after the  Distribution  Date, mail a brief
summary of such  adjustment to each holder of a Right  Certificate in accordance
with Section 25 hereof.

The Rights Agent shall be fully protected in relying on any such certificate and
on any  adjustment  therein  and  shall  not be  obligated  or  responsible  for
calculating  any adjustment nor shall it be deemed to have knowledge of any such
adjustment unless it shall have received such a certificate.

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

     (a) In the event that,  following the Share Acquisition  Date,  directly or
indirectly:

                                       20
<PAGE>

         (i)  The Company shall  consolidate  with,  or merge with or into,  any
other  Person  and  the  Company  shall  not  be  the  continuing  or  surviving
corporation of such consolidation or merger; or

        (ii)  Any Person shall  consolidate with  the Company,  or merge with or
into  the  Company  and  the  Company  shall  be  the  continuing  or  surviving
corporation of such merger or consolidation  and, in connection with such merger
or  consolidation,  all or part of the Common  Shares  shall be changed  into or
exchanged for stock or other securities of any other Person or cash or any other
property; 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 (including, without limitation,  securities creating any
obligation  on  the  part  of  the  Company  and/or  any  of  its  Subsidiaries)
representing  in the  aggregate  more than 50% of the assets or earning power of
the  Company and its  Subsidiaries  (taken as a whole) to any Person or Persons,
then,  and in each such case,  proper  provision  shall be made so that (A) each
holder of a Right (except as otherwise  provided  herein) shall  thereafter have
the right to receive,  upon the exercise thereof in accordance with the terms of
this  Agreement  at an  exercise  price per Right  equal to the  product  of the
then-current  Purchase Price multiplied by the number of one one-hundredths of a
Preferred Share for which a Right was exercisable immediately prior to the first
occurrence of a Triggering Event, such number of validly  authorized and issued,
fully paid, nonassessable and freely tradeable Common Shares of the Issuer, free
and clear of any liens, encumbrances and other adverse claims and not subject to
any rights of call or first refusal, as shall be equal to the result obtained by
(x)  multiplying  the   then-current   Purchase  Price  by  the  number  of  one
one-hundredths  for which a Right is exercisable  immediately prior to the first
occurrence  of a Triggering  Event and  dividing  that product by (y) 50% of the
current per share  market price of the Common  Shares of the Issuer  (determined
pursuant to Section 11(d) hereof), on the date of consummation of such Flip-over
Event;  (B) the Issuer  shall  thereafter  be liable for, and shall  assume,  by
virtue of the  consummation  of such Flip-over  Event,  all the  obligations and
duties of the Company  pursuant to this Agreement;  (C) the term "Company" shall
thereafter be deemed to refer to the Issuer;  and (D) the Issuer shall take such
steps (including,  without limitation, the reservation of a sufficient number of
its  Common  Shares  to  permit  the  exercise  of all  outstanding  Rights)  in
connection  with  such  consummation  as may be  necessary  to  assure  that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may be
possible,  in  relation to its Common  Shares  thereafter  deliverable  upon the
exercise of the Rights. At any time prior to the Distribution Date, the Board of
Directors  of the  Company  may  declare  that in lieu  of a cash  payment,  the
registered  holder of a Right  Certificate  may  exercise  the Rights  evidenced
thereby (except as otherwise provided herein) in whole or in part upon surrender
of the Right  Certificate  with an  election to  exercise  such  Rights  without
payment of cash on the reverse side thereof duly completed.  With respect to any
Rights as to which such an election is made,  the holder shall  receive a number
of Common  Shares or other  securities of the Issuer having a value equal to the
difference between (i) the value of the Common Shares or other securities of the
Issuer  that  would  have  been  issuable  upon  payment  of the cash  amount as
described above, and (ii) the amount of such cash payment.

                                       21

     (b) For purposes of this Section 13, "Issuer" shall mean (i) in the case of
any Flip-over  Event  described in Sections  13(a)(i) or (ii) above,  the Person
that is the continuing,  surviving, resulting or Acquiring Person (including the
Company as the continuing or surviving corporation of a transaction described in
Section 13(a)(ii) above),  and (ii) in the case of any Flip-over Event described
in Section 13(a)(iii) above, the Person that is the party receiving the greatest
portion  of  the  assets  or  earning  power  (including,   without  limitation,
securities  creating any obligation on the part of the Company and/or any of its
Subsidiaries)   transferred   pursuant  to  such  transaction  or  transactions;
provided,  however,  that,  in any such  case,  (A) if (1) no  class  of  equity
security  of such  Person  is,  at the  time of such  merger,  consolidation  or
transaction  and has been  continuously  over  the  preceding  12-month  period,
registered  pursuant to Section 12 of the Exchange Act, and (2) such Person is a
Subsidiary,  directly  or  indirectly,  of  another  Person,  a class of  equity
security of which is and has been so  registered,  the term "Issuer"  shall mean
such other  Person;  and (B) in case such  Person is a  Subsidiary,  directly or
indirectly,  of more than one Person,  a class of equity security of two or more
of which are and have been so registered, the term "Issuer" shall mean whichever
of such  Persons  is the  Issuer of the  equity  security  having  the  greatest
aggregate  market value.  For purposes of this Section 13, neither  "Issuer" nor
"Person"  shall mean any Person or such Person's  Affiliates  and Associates who
were the Beneficial Owner,  individually or collectively,  of 15% or more of the
Common Shares outstanding on May 4, 1999.  Notwithstanding the foregoing, if the
Issuer in any of the Flip-over Events listed above is not a corporation or other
legal entity having outstanding equity securities,  then, and in each such case,
(x) if the Issuer is directly or  indirectly  wholly owned by a  corporation  or
other legal entity having outstanding equity securities,  then all references to
Common  Shares of the  Issuer  shall be deemed to be  references  to the  Common
Shares of the  corporation  or other  legal  entity  having  outstanding  equity
securities  which  ultimately  controls the Issuer,  and (y) if there is no such
corporation  or other legal entity having  outstanding  equity  securities,  (i)
proper provision shall be made so that the Issuer shall create or otherwise make
available  for  purposes of the  exercise of the Rights in  accordance  with the
terms of this Agreement, a kind or kinds of security or securities having a fair
market  value at least equal to the  economic  value of the Common  Shares which
each  holder of a Right  would have been  entitled  to receive if the Issuer had
been a corporation or other legal entity having  outstanding  equity securities;
and (ii) all other  provisions  of this  Agreement  shall apply to the Issuer of
such securities as if such securities were Common Shares.

     (c) The Company shall not consummate any Flip-over Event, unless the Issuer
shall have a sufficient  number of authorized Common Shares (or other securities
as  contemplated  in Section 13(b) above) which have not been issued or reserved
for  issuance to permit the  exercise in full of the Rights in  accordance  with
this Section 13 and unless prior to such consummation the Company and the Issuer
shall have executed and delivered to the Rights Agent a  supplemental  agreement
providing for the terms set forth in subsections  (a) and (b) of this Section 13
and further  providing that as promptly as practicable after the consummation of
any Flip-over Event, the Issuer shall:

                                       22
<PAGE>

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

        (ii) Take  all 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; and

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

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

     SECTION 14. Fractional Rights And Fractional Securities.

     (a) The Company  shall not be required to issue  fractions  of Rights or to
distribute Right Certificates which evidence  fractional Rights. In lieu of such
fractional  Rights,  the Company  shall pay as promptly  as  practicable  to the
registered  holders  of  the  Right  Certificates  with  regard  to  which  such
fractional  Rights  otherwise would 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  otherwise  would have been issuable.  The closing
price for any day shall be the last sale price, regular way, or, in case no such
sale takes place on such day,  the average of the closing bid and asked  prices,
regular  way,  in  either  case  as  reported  in  the  principal   consolidated
transaction  reporting  system with respect to securities  listed or admitted to
trading on the NYSE or, if the Rights are not listed or  admitted  to trading on
the NYSE, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national  securities exchange
on which the Rights are listed or  admitted to trading or, if the Rights are not
listed or  admitted to trading on any  national  securities  exchange,  the last
quoted  price or, if not so  quoted,  the  average of the high bid and low asked
prices in the over-the-counter  market, as reported by NYSE or such other system
then in use or,  if on any  such  date the  Rights  are not  quoted  by any such
organization,  the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights selected by the Board of
Directors of the  Company.  If on any such date no such market maker is making a
market in the Rights the fair value of the Rights on such date as  determined in
good faith by the Board of Directors of the Company shall be used.

                                       23

     (b) The  Company  shall not be  required to issue  fractions  of  Preferred
Shares (other than fractions which are integral  multiples of one  one-hundredth
of a Preferred Share) upon exercise of the Rights or to distribute  certificates
which  evidence  fractional  Preferred  Shares (other than  fractions  which are
integral  multiples of one  one-hundredth  of a Preferred  Share).  Fractions of
Preferred Shares in integral multiples of one one-hundredth of a Preferred Share
may,  at the  election of the  Company,  be  evidenced  by  depositary  receipts
pursuant to an  appropriate  agreement  between  the  Company  and a  depositary
selected by it,  provided that such agreement  shall provide that the holders of
such depositary  receipts shall have 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-hundredth of a Preferred Share, the
Company may pay to any Person to whom or which such fractional  Preferred Shares
would  otherwise be issuable an amount in cash equal to the same fraction of the
current market value of one Preferred Share. For purposes of this Section 14(b),
the current  market value of one  Preferred  Share shall be the closing price of
the Preferred  Shares (as  determined in the same manner as set forth for Common
Shares in the second  sentence of Section  11(d)(i)  hereof) for the Trading Day
immediately prior to the date of such exercise;  provided,  however, that if the
closing price of the Preferred Shares cannot be so determined, the closing price
of the Preferred Shares for such Trading Day shall be conclusively  deemed to be
an amount equal to the closing price of the Common Shares  (determined  pursuant
to the  second  sentence  of  Section  11(d)(i)  hereof)  for such  Trading  Day
multiplied  by 100 (as such  number  may be  appropriately  adjusted  to reflect
events  such as stock  splits,  stock  dividends,  recapitalizations  or similar
transactions  relating  to the Common  Shares  occurring  after the date of this
Agreement); and provided further, however, that if neither the Common Shares nor
the  Preferred  Shares are publicly held or listed or admitted to trading on any
national securities exchange,  or the subject of available bid and asked quotes,
the current  market value of one  Preferred  Share shall be  determined  in good
faith by the Board of Directors of the Company.

     (c) Following the occurrence of a Triggering  Event,  the Company shall not
be required to issue  fractions of Common  Shares or other  securities  issuable
upon  exercise  or exchange of the Rights or to  distribute  certificates  which
evidence any such fractional securities.  In lieu of issuing any such fractional
securities,  the Company may pay to any Person to whom or which such  fractional
securities  would  otherwise  be  issuable  an amount in cash  equal to the same
fraction of the current market value of one such security.  For purposes of this
Section  14(c),  the current  market value of one Common Share or other security
issuable  upon the  exercise or exchange  of Rights  shall be the closing  price
thereof (as  determined in the same manner as set forth for Common Shares in the
second  sentence of Section  11(d)(i)  hereof)  for the Trading Day  immediately
prior to the date of such  exercise  or  exchange;  provided,  however,  that if
neither the Common  Shares nor any such other  securities  are publicly  held or
listed or  admitted  to  trading on any  national  securities  exchange,  or the
subject of  available  bid and asked  quotes,  the current  market  value of one
Common Share or such other  security  shall be  determined  in good faith by the
Board of Directors of the Company.

                                       24

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

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

     (c) The Company and the Rights Agent may deem and treat the Person in whose
name the Right  Certificate (or, prior to the Distribution  Date, the associated
Common Share certificate) is registered as the absolute owner thereof and of the
Rights evidenced thereby  (notwithstanding any notations of ownership or writing
on the Right  Certificate or the  associated  Common Share  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.

     (d) Such holder expressly waives any right to receive any fractional Rights
and any fractional  securities  upon exercise or exchange of a Right,  except as
otherwise provided in Section 14 hereof.

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

                                       25
<PAGE>


by a  court  of  competent  jurisdiction  or by a  governmental,  regulatory  or
administrative  agency  or  commission,  or any  statute,  rule,  regulation  or
executive  order   promulgated  or  enacted  by  any   governmental   authority,
prohibiting or otherwise restraining  performance of such obligation;  provided,
however,  that the  Company  shall use its best  efforts to have any such order,
decree or ruling lifted or otherwise overturned as soon as possible.

     SECTION 17. Right Certificate  Holder Not Deemed a Shareholder.  No holder,
as such, of any Right Certificate  shall be entitled to vote,  receive dividends
or be deemed for any  purpose  the holder of the  Preferred  Shares or any other
securities of the Company which may at any time be issuable upon the exercise of
the Rights  represented  thereby,  nor shall anything contained herein or in any
Right  Certificate  be  construed  to  confer  upon  the  holder  of  any  Right
Certificate,  as such,  any of the rights of a shareholder of the Company or any
right to vote for the  election of  Directors  or upon any matter  submitted  to
shareholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
shareholders  (except as provided in Section 24 hereof), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or Rights  evidenced by
such  Right  Certificate  shall  have  been  exercised  in  accordance  with the
provisions of this Agreement or exchanged  pursuant to the provisions of Section
27 hereof.

     SECTION 18. Concerning 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, its directors,  officers,  employees and agents for,
and to hold each of them harmless against,  any loss,  liability,  suit, action,
proceeding 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 or such other  indemnified  party in connection with the acceptance
and  administration  of this Agreement or the  performance of the Rights Agent's
duties  hereunder,  including  the costs and expenses of  defending  against any
claim of liability arising therefrom, directly or indirectly.

     (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 or the performance of the Rights Agent's duties
hereunder  in reliance  upon any Right  Certificate  or  certificate  evidencing
Preferred Shares or other securities of the Company, instrument of assignment or
transfer, power of attorney, endorsement,  affidavit, letter, notice, direction,
consent, certificate, statement, or other paper or document believed by it to be
genuine  and  to  be  signed,   executed  and,  where  necessary,   verified  or
acknowledged, by the proper Person or Persons.

     (c) The indemnity  provided in this Section 18 shall survive the expiration
of the Rights and the termination of this Agreement.

                                       26
<PAGE>

     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 that such corporation would be eligible for appointment
as a successor  Rights Agent under the provisions of Section 21 hereof.  In case
at the time such  successor  Rights Agent shall succeed to the agency created by
this Agreement,  any of the Right Certificates shall have been countersigned but
not delivered, any such successor Rights Agent may adopt the countersignature of
the   predecessor   Rights  Agent  and  deliver  such  Right   Certificates   so
countersigned;  and in case at that time any of the Right Certificates shall not
have been  countersigned,  any successor Rights Agent may countersign such Right
Certificates  either in the name of the predecessor  Rights Agent or in the name
of the  successor  Rights Agent;  and in all such cases such Right  Certificates
shall  have  the full  force  provided  in the  Right  Certificates  and in this
Agreement.

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

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

     (a) The  Rights  Agent may  consult  with legal  counsel  (who may be legal
counsel for the  Company),  and the 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 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 be
proved or  established  by the Company  prior to taking or suffering  any action
hereunder,  such fact or matter  (unless  other  evidence in respect  thereof be
herein  specifically  prescribed)  may be deemed to be  conclusively  proved and
established by a certificate signed by any one of the Chairman of the Board, the
President  or any Vice  President  of the  Company and  delivered  to the Rights
Agent; and such certificate shall be full authorization to the Rights

                                       27
<PAGE>

Agent for any action taken or suffered in good faith by it under the  provisions
of this Agreement in reliance upon such certificate.

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

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

     (e) The Rights  Agent shall not be under any  responsibility  in respect of
the validity of this Agreement or the execution and delivery  hereof (except the
due  execution  and  delivery  hereof by the Rights  Agent) or in respect of the
validity or  execution  of any Right  Certificate  (except its  countersignature
thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Right  Certificate;
nor shall it be responsible for any adjustment  required under the provisions of
Section 11 or Section  13 hereof  (including  any  adjustment  which  results in
Rights  becoming  void) or responsible  for the manner,  method or amount of any
such adjustment or the ascertaining of the existence of facts that would require
any such adjustment  (except with respect to the exercise of Rights evidenced by
Right Certificates after actual notice of any such adjustment);  nor shall it by
any act  hereunder  be deemed to make any  representation  or warranty as to the
authorization  or reservation  of any shares of stock or other  securities to be
issued pursuant to this Agreement or any Right  Certificate or as to whether any
shares of stock or other securities 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  President  or any Vice  President of the
Company,  and to apply to such officers for advice or instructions in connection
with its duties,  and it shall not be liable for any action taken or suffered to
be taken by it in good faith in accordance with instructions of any such officer
or for any delay in acting while awaiting  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 Agreement and the date on 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 the date
specified in such  application  (which date shall not be less than five Business
Days after the date any officer of the Company actually receives such

                                       28
<PAGE>

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 shareholder,  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 the Rights Agent was not grossly  negligent in
the selection and continued  employment  thereof.  The Rights Agent shall not be
under  any duty or  responsibility  to  insure  compliance  with any  applicable
federal or state  securities laws in connection  with the issuance,  transfer or
exchange of Right Certificates.

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

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

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

     (m) 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.

     SECTION  21.  Change of Rights  Agent.  The Rights  Agent or any  successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon 30  calendar  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 Right  Certificates  by  first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
30 calendar  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 Right  Certificates by first-class mail. If the Rights Agent shall resign
or be removed or shall otherwise become  incapable of acting,  the Company shall
appoint a successor to the Rights Agent.  If the Company shall fail to make such
appointment  within a period of 30  calendar  days after  giving  notice of such
removal  or  after  it has been  notified  in  writing  of such  resignation  or
incapacity by the resigning or incapacitated  Rights Agent or by the holder of a
Right Certificate (who shall, with such notice, submit his Right Certificate for
inspection by the Company),  then the registered holder of any Right Certificate
may apply to any court of competent  jurisdiction  for the  appointment of a new
Rights Agent. Any successor Rights Agent, whether appointed by the Company or by
such a court, shall be a corporation organized and doing business under the laws
of the  United  States or of the  States of Florida or New York (or of any other
state of the  United  States so long as such  corporation  is  authorized  to do
business as a banking institution in the States of Florida or New York), in good
standing,  having a principal office in the States of Florida or New York, which
is authorized under such laws to exercise  corporate trust powers and is subject
to supervision or examination by federal or state authority and which has at the
time of its  appointment  as Rights  Agent a combined  capital and surplus of at
least $5 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 Right Certificates.  Failure to give any notice
provided  for in this  Section 21,  however,  or any defect  therein,  shall not
affect the  legality  or validity  of the  resignation  or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

     SECTION 22. Issuance of New Right Certificates.  Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary,  the Company may,
at its option,  issue new Right  Certificates  evidencing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change in
the Purchase Price per share and the number or kind of securities  issuable upon
exercise of the Rights made in accordance with the provisions of this Agreement.
In addition,  in  connection  with the issuance or sale by the Company of Common
Shares  following the  Distribution  Date and prior to the Expiration  Date, the
Company

                                       30
<PAGE>

     (a) Shall,  with respect to Common Shares so issued or sold pursuant to the
exercise or conversion of securities issued prior to the Distribution Date which
are exercisable for, or convertible into Common Shares, and

     (b) May, in any other case, if deemed  necessary,  appropriate or desirable
by the Board of Directors of the Company, issue Right Certificates  representing
an  equivalent  number of Rights as would  have been  issued in  respect of such
Common Shares if they had been issued or sold prior to the Distribution Date, as
appropriately adjusted as provided herein as if they had been so issued or sold;
provided, however, that (i) no such Right Certificate shall be issued if, and to
the  extent  that,  in its good faith  judgment  the Board of  Directors  of the
Company shall have determined that the issuance of such Right  Certificate could
have a material  adverse tax consequence to the Company or to the Person to whom
or which  such Right  Certificate  otherwise  would be issued,  and (ii) no such
Right  Certificate  shall be issued  if,  and to the  extent  that,  appropriate
adjustment otherwise shall have been made in lieu of the issuance thereof.

     SECTION 23. Redemption.

     (a) Prior to the  Expiration  Date,  the Board of  Directors of the Company
may,  at its  option,  redeem all but not less than all of the  then-outstanding
Rights at the Redemption Price at any time prior to the Close of Business on the
later of (i) the Distribution Date and (ii) the Share Acquisition Date.

     (b)  Immediately  upon the action of the Board of  Directors of the Company
ordering  the  redemption  of the Rights,  and  without  any further  action and
without any notice,  the right to exercise  the Rights shall  terminate  and the
only  right  thereafter  of the  holders  of  Rights  shall  be to  receive  the
Redemption Price.  Promptly after the action of its Board of Directors  ordering
the redemption of the Rights,  the Company shall publicly  announce such action,
and within 10 calendar  days  thereafter,  the Company shall give notice of such
redemption to 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 Company; provided, however, that the failure to give, or any defect
in, any such  notice  shall not affect the  validity  of the  redemption  of the
Rights. Any notice which is mailed in the manner herein provided shall be deemed
given,  whether or not the holder receives the notice.  The notice of redemption
mailed to the  holders of Rights  shall state the method by which the payment of
the  Redemption  Price will be made.  The Company  may,  at its option,  pay the
Redemption Price in cash, Common Shares (based upon the current per share market
price of the Common Shares (determined  pursuant to Section 11(d) hereof) at the
time of redemption) or any other form of consideration deemed appropriate by the
Board of  Directors  of the Company  (based  upon the fair market  value of such
other consideration, determined by the Board of Directors of the Company in good
faith) or any combination thereof.

     (c) At any  time  following  the  Share  Acquisition  Date,  the  Board  of
Directors  of the Company may  relinquish  the right to redeem the Rights  under
this Section 23 by duly adopting a resolution to that effect.  Immediately  upon
adoption of such resolution, the

                                       31
<PAGE>

rights of the Board of  Directors  of the  Company to redeem  the  Rights  shall
terminate without further action and without any notice. Promptly after adoption
of such a resolution, the Company shall publicly announce such action; provided,
however,  that the failure to give,  or any defect in, any such notice shall not
affect the validity of the action of the Board of Directors of the Company.

     SECTION 24. Notice of Certain Events.

     (a) In case, after the Distribution  Date, the Company shall propose (i) to
pay any  dividend  payable  in stock of any class to the  holders  of  Preferred
Shares or to make any other  distribution  to the  holders of  Preferred  Shares
(other than a regular  periodic cash dividend),  (ii) to offer to the holders of
Preferred Shares rights, options or warrants to subscribe for or to purchase any
additional  Preferred  Shares  or  shares  of  stock of any  class or any  other
securities,  rights or  options,  (iii) to effect  any  reclassification  of its
Preferred Shares (other than a  reclassification  involving only the subdivision
of outstanding  Preferred  Shares),  (iv) to effect any  consolidation or merger
into or with, or to effect any sale or other  transfer (or to permit one or more
of its  Subsidiaries  to  effect  any  sale or other  transfer),  in one or more
transactions,  of  assets  or  earning  power  (including,  without  limitation,
securities  creating any obligation on the part of the Company and/or any of its
Subsidiaries)  representing more than 50% of the assets and earning power of the
Company and its Subsidiaries,  taken as a whole, to any other Person or Persons,
(v) to effect the liquidation, dissolution or winding up of the Company, or (vi)
to declare or pay any dividend on the Common Shares  payable in Common Shares or
to effect a subdivision,  combination or  reclassification  of the Common Shares
then,  in each such  case,  the  Company  shall  give to each  holder of a Right
Certificate,  in  accordance  with Section 25 hereof,  a notice of such proposed
action,  which  shall  specify  the record  date for the  purposes of such stock
dividend,  distribution or offering of rights,  options or warrants, or the date
on  which  such   reclassification,   consolidation,   merger,  sale,  transfer,
liquidation,  dissolution,  or  winding  up is to take  place  and  the  date of
participation  therein  by the  holders of the Common  Shares  and/or  Preferred
Shares,  if any such date is to be fixed,  and such notice shall be so given, in
the case of any action covered by clause (i) or (ii) above, at least 10 calendar
days prior to the record date for  determining  holders of the Preferred  Shares
for purposes of such action, and, in the case of any such other action, at least
10 calendar days prior to the date of the taking of such proposed  action or the
date of  participation  therein  by the  holders  of the  Common  Shares  and/or
Preferred Shares whichever shall be the earlier.

     (b) In case any Triggering  Event shall occur,  then, in any such case, the
Company  shall as soon as  practicable  thereafter  give to the Rights Agent and
each holder of a Right  Certificate,  in  accordance  with Section 25 hereof,  a
notice of the  occurrence  of such event,  which shall specify the event and the
consequences of the event to holders of Rights.

                                       32
<PAGE>

     SECTION 25. Notices.

     (a) Notices or demands  authorized by this Agreement to be given or made by
the Rights Agent or by the holder of any Right  Certificate to or on the Company
shall  be  sufficiently  given  or made if sent  by  first-class  mail,  postage
prepaid,  addressed  (until another  address is filed in writing with the Rights
Agent) as follows:

                       Attention: Chief Financial Officer

     (b) Subject to the  provisions  of Section 21 hereof,  any notice or demand
authorized by this Agreement to be given or made by the Company or by the holder
of any Right  Certificate to or on the Rights Agent shall be sufficiently  given
or made if sent by first-class mail,  postage prepaid,  addressed (until another
address is filed in writing with the Company) as follows:

                       Attention: Shareholder Services Group

     (c) Notices or demands  authorized by this Agreement to be given or made by
the Company or the Rights Agent to the holder of any Right  Certificate  (or, if
prior to the  Distribution  Date,  to the holder of any  certificate  evidencing
Common Shares) shall be sufficiently  given or made if sent by first-class mail,
postage prepaid, addressed to such holder at the address of such holder as shown
on the registry books of the Company.

     SECTION 26. Supplements And Amendments.  Prior to the Distribution Date and
subject to the last sentence of this Section 26, if the Company so directs,  the
Company and the Rights  Agent shall  supplement  or amend any  provision of this
Agreement  without  the  approval of any  holders of  certificates  representing
Common  Shares.  From and after the  Distribution  Date and  subject to the last
sentence of this  Section  26, if the  Company so  directs,  the Company and the
Rights Agent shall  supplement or amend this  Agreement  without the approval of
any holders of Right  Certificates  in order (i) to cure any ambiguity,  (ii) to
correct or supplement any provision  contained  herein which may be defective or
inconsistent with any other provisions herein,  (iii) to shorten or lengthen any
time period hereunder,  or (iv) to supplement or amend the provisions  hereunder
in  any  manner  which  the  Company  may  deem  desirable,  including,  without
limitation,  the addition of other  events  requiring  adjustment  to the Rights
under  Sections 11 or 13 hereof or procedures  relating to the redemption of the
Rights, which supplement or amendment shall not, in the good faith determination
of the Board of Directors of the Company,  adversely affect the interests of the
holders of Right Certificates (other than an Acquiring Person or an Affiliate

                                       33
<PAGE>

or Associate of an Acquiring Person). Upon the delivery of a certificate from an
officer of the Company which states that the proposed supplement or amendment is
in compliance  with the terms of this Section 26, the Rights Agent shall execute
such supplement or amendment;  provided, however, that the failure or refusal of
the Rights Agent to execute such  supplement  or amendment  shall not affect the
validity of any  supplement  or amendment  adopted by the Company,  any of which
shall be  effective  in  accordance  with  the  terms  thereof.  Notwithstanding
anything in this Agreement to the contrary,  no supplement or amendment shall be
made which decreases the stated Redemption Price or the period of time remaining
until the Final Expiration Date or which modifies a time period relating to when
the Rights may be redeemed  at such time as the Rights are not then  redeemable,
and no supplement  or amendment  that changes the rights or duties of the Rights
Agent under this  Agreement  shall be  effective  without the  execution of such
supplement or amendment by the Rights Agent.

     SECTION 27. Exchange.

     (a) The Board of Directors  of the Company may, at its option,  at any time
after the Distribution Date,  exchange all or part of the  then-outstanding  and
exercisable  Rights  (which  shall not  include  Rights  that have  become  void
pursuant to the provisions of Section  11(a)(ii) hereof) for Common Shares at an
exchange ratio of one Common Share per Right,  appropriately adjusted to reflect
any stock split, stock dividend or similar transaction  occurring after the date
hereof  (such  exchange  ratio being  hereinafter  referred to as the  "Exchange
Ratio").  Notwithstanding  the  foregoing,  the Board of Directors  shall not be
empowered to effect such  exchange at any time after any Person  (other than the
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),  who or which,  together  with all  Affiliates  and
Associates of such Person,  becomes the  Beneficial  Owner of 50% or more of the
Common Shares then outstanding.

     (b)  Immediately  upon the action of the Board of  Directors of the Company
ordering  the  exchange of any Rights  pursuant  to Section  27(a)  hereof,  and
without any further  action and without any notice,  the right to exercise  such
Rights shall terminate and the only right with respect to such Rights thereafter
of the 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.  Promptly  after the  action of the Board of  Directors  of the
Company  ordering the exchange of any Rights  pursuant to Section  27(a) hereof,
the Company shall  publicly  announce  such action,  and within 10 calendar days
thereafter  shall give 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;  provided,  however,  that the failure to give, or any defect in,
such notice shall not affect the validity of such exchange.  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 shall state the method
by which the exchange of the Common  Shares for Rights

                                       34
<PAGE>

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 11(a)(ii) hereof) held by each holder of Rights.

     (c) In any  exchange  pursuant  to this  Section  27, the  Company,  at its
option,  may  substitute  for any Common  Share  exchangeable  for a Right,  (i)
equivalent  Common Shares (as such term is used in Section  11(a)(iii)  hereof),
(ii) cash, (iii) debt securities of the Company,  (iv) other assets,  or (v) any
combination of the foregoing,  in any event having an aggregate  value which the
Board of  Directors  of the Company  shall have  determined  in good faith to be
equal to the current  market value of one Common Share  (determined  pursuant to
Section  11(d)  hereof) on the Trading  Day  immediately  preceding  the date of
exchange pursuant to this Section 27.

     SECTION 28. Successors; Certain Covenants. 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. 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 Right  Certificates  (and,  prior to the Distribution
Date,  the Common  Shares) any legal or equitable  right,  remedy or claim under
this Agreement;  but this Agreement shall be for the sole and exclusive  benefit
of the  Company,  the  Rights  Agent  and the  registered  holders  of the Right
Certificates (or prior to the Distribution Date, the Common Shares).

     SECTION 30. Determinations And Actions by The Board of Directors,  Etc. The
Board of Directors of the Company shall have the  exclusive  power and authority
to administer this Agreement and to exercise all rights and powers  specifically
granted to the Board, or the Company, or as may be necessary or advisable in the
administration of this Agreement,  including,  without limitation, the right and
power to (i)  interpret  the  provisions  of this  Agreement,  and (ii) make all
determinations  deemed  necessary or advisable  for the  administration  of this
Agreement  (including,  without  limitation,  a  determination  to redeem or not
redeem the Rights or to amend the  Agreement,  whether a Person is an  Acquiring
Person and whether any proposed amendment adversely affects the interests of the
holders  of  Right  Certificates).  For  all  purposes  of this  Agreement,  any
calculation  of the number of Common Shares or other  securities  outstanding at
any  particular  time,  including  for purposes of  determining  the  particular
percentage of such  outstanding  Common Shares or any other  securities of which
any Person is the Beneficial  Owner,  shall be made in accordance  with the last
sentence of Rule 13d-3(d)(1)(i)  under the Exchange Act as in effect on the date
of  this  Agreement.  All  such  actions,   calculations,   interpretations  and
determinations  (including, for purposes of clause (y) below, all omissions with
respect  to the  foregoing)  which are done or made by the board in good  faith,
shall (x) be final, conclusive and binding on the Company, the Rights Agent, the
holders of the Right Certificates and all other parties, and (y) not subject the
Board to any liability to the holders of the Right Certificates.

                                       35
<PAGE>

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

     SECTION 32. Governing Law. This Agreement and each Right Certificate issued
hereunder  shall be deemed to be a contract made under the internal  substantive
laws of the State of  Florida  and for all  purposes  shall be  governed  by and
construed  in  accordance  with  the  internal  substantive  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.

                                       36

                                     FORM OF
                              ARTICLES OF AMENDMENT
                                   RELATING TO
                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
                                       OF
                          FLORIDA ROCK INDUSTRIES, INC.

     Pursuant to the provisions of Sections 607.0602 and 607.1002 of the Florida
Business Corporation Act (the "Act"), the undersigned, on behalf of Florida Rock
Industries, Inc. (the "Corporation"), hereby submits the following information:

     1. The name of the Corporation is FLORIDA ROCK INDUSTRIES, INC.

     2.  Pursuant to Sections  607.0602 and 607.1002 of the Act, the Articles of
Incorporation  of the  Corporation  are hereby amended to authorize and create a
new series of preferred  stock,  par value $.01 per share.  The  designation and
amount  thereof  and  the  powers,   designations,   preferences  and  relative,
participating,  optional  and other  special  rights  of the  shares of such new
series of preferred  stock and the  qualifications,  limitations or restrictions
thereof are as follows:

                            I. Designation and Amount

     The  shares of such new  series  shall be  designated  as  "Series A Junior
     Participating  Preferred  Stock" (the  "Series A Preferred  Stock") and the
     number  of  shares  constituting  the  Series A  Preferred  Stock  shall be
     500,000.  Such number of shares may be increased or decreased by resolution
     of the Board of  Directors;  provided,  that no decrease  shall  reduce the
     number  of shares of  Series A  Preferred  Stock to a number  less than the
     number of shares then  outstanding  plus the number of shares  reserved for
     issuance upon the exercise of  outstanding  options,  rights or warrants or
     upon the conversion of any outstanding securities issued by the Corporation
     convertible into Series A Preferred Stock.

                         II. Dividends and Distributions

     (A)  Subject  to the  rights of the  holders of any shares of any series of
Preferred  Stock (or any similar stock) ranking prior and superior to the Series
A Preferred  Stock with respect to dividends,  the holders of shares of Series A
Preferred  Stock,  in preference to the holders of Common Stock,  par value $.10
per share (the  "Common  Stock"),  of the  Corporation,  and of any other junior
stock,  shall be entitled to receive,  when,  as and if declared by the Board of
Directors out of funds legally  available for the purpose,  quarterly  dividends
payable in cash on the first day of March, June,  September and December in

                                      A-1
<PAGE>

each year (each  such date being  referred  to herein as a  "Quarterly  Dividend
Payment Date"),  commencing on the first Quarterly  Dividend  Payment Date after
the first issuance of a share or fraction of a share of Series A Preferred Stock
(the "First Quarterly  Dividend Payment Date"),  in an amount per share (rounded
to the nearest  cent)  equal to the greater of (i) $1.00 or (ii)  subject to the
provision  for  adjustment  hereinafter  set forth,  100 times the aggregate per
share amount of all cash dividends, and 100 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 Preferred Stock. In the
event  the  Corporation  shall  at  any  time  (a)  declare  a  dividend  on the
outstanding  shares of Common  Stock  payable  in  shares of Common  Stock,  (b)
subdivide the  outstanding  shares of Common Stock,  (c) combine the outstanding
shares of Common Stock in a smaller number of shares, or (d) issue any shares of
its capital  stock in a  reclassification  of the  outstanding  shares of Common
Stock (including any such reclassification in connection with a consolidation or
merger in which the  Corporation  is the  continuing or surviving  corporation),
then,  in each  such  case and  regardless  of  whether  any  shares of Series A
Preferred Stock are then issued or  outstanding,  the amount to which holders of
shares of Series A Preferred Stock would otherwise be entitled immediately prior
to such event under clause (ii) of the preceding  sentence  shall be adjusted by
multiplying  such amount by a fraction,  the numerator of which is the number of
shares  of  Common  Stock  outstanding  immediately  after  such  event  and the
denominator  of  which is the  number  of  shares  of  Common  Stock  that  were
outstanding immediately prior to such event.

     (B) The Corporation  shall declare a dividend or distribution on the Series
A Preferred  Stock as provided in paragraph  (A) of this Section II  immediately
after it declares a dividend or  distribution  on the Common Stock (other than a
dividend  payable in shares of Common Stock);  provided,  however,  that, in the
event no dividend or  distribution  shall have been declared on the Common Stock
during the period  between  any  Quarterly  Dividend  Payment  Date and the next
subsequent Quarterly Dividend Payment Date, a dividend of $1.00 per share on the
Series A  Preferred  Stock  shall  nevertheless  be payable  on such  subsequent
Quarterly Dividend Payment Date.

     (C) Dividends shall begin to accrue and be cumulative on outstanding shares
of Series A  Preferred  Stock  from the  Quarterly  Dividend  Payment  Date next
preceding the date of issue of such shares, unless (i) 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 the first issuance of a share of Series A Preferred  Stock,  or (ii) 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 Preferred Stock entitled
to receive a quarterly dividend and before such Quarterly Dividend Payment Date,
in either of which events such dividends shall begin to accrue and be cumulative
from such Quarterly  Dividend  Payment Date.  Accrued but unpaid dividends shall
not bear interest.  Dividends paid on the shares of Series A Preferred  Stock in
an amount less than

                                      A-2
<PAGE>

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 Preferred Stock entitled to
receive payment of a dividend or  distribution  declared  thereon,  which record
date  shall not be more than 60  calendar  days  prior to the date fixed for the
payment thereof.

                               III. Voting Rights

     The holders of shares of Series A Preferred  Stock shall have the following
voting rights:

     (A) Subject to the provision for  adjustment  hereinafter  set forth,  each
share of Series A Preferred  Stock shall entitle the holder thereof to 100 votes
on all matters  submitted to a vote of the shareholders of the  Corporation.  In
the event  the  Corporation  shall at any time (i)  declare  a  dividend  on the
outstanding  shares of Common  Stock  payable  in shares of Common  Stock,  (ii)
subdivide the outstanding  shares of Common Stock, (iii) combine the outstanding
shares of Common Stock in a smaller  number of shares,  or (iv) issue any shares
of its capital stock in a  reclassification  of the outstanding shares of Common
Stock (including any such reclassification in connection with a consolidation or
merger in which the  Corporation  is the  continuing or surviving  corporation),
then,  in each  such  case and  regardless  of  whether  any  shares of Series A
Preferred Stock are then issued or outstanding, the number of votes per share to
which holders of shares of Series A Preferred  Stock would otherwise be entitled
immediately  prior to such event shall be adjusted by multiplying such number by
a  fraction,  the  numerator  of which is the  number of shares of Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

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

     (C) Except as set forth herein, or as otherwise provided by law, holders of
Series A 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.

                                      A-3
<PAGE>

                            IV. Certain Restrictions

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

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

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

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

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

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

                              V. Reacquired Shares

     Any shares of Series A Preferred Stock  purchased or otherwise  acquired by
the Corporation in any manner whatsoever shall be retired and cancelled promptly
after the

                                      A-4
<PAGE>

acquisition  thereof.  All such  shares  shall  upon their  cancellation  become
authorized but unissued shares of Preferred Stock and may be reissued as part of
a new series of Preferred  Stock subject to the conditions and  restrictions  on
issuance set forth  herein,  in the Articles of  Incorporation,  or in any other
articles of amendment  creating a series of Preferred Stock or any similar stock
or as otherwise required by law.

                   VI. Liquidation, Dissolution or Winding Up

     Upon any  liquidation,  dissolution  or winding up of the  Corporation,  no
distribution  shall be made (A) to the holders of shares of stock ranking junior
(either as to dividends or upon  liquidation,  dissolution or winding up) to the
Series A Preferred Stock unless,  prior thereto, the holders of shares of Series
A Preferred  Stock shall have received  $100 per share,  plus an amount equal to
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment;  provided,  however,  that the holders of shares of
Series A Preferred  Stock shall be entitled to receive an  aggregate  amount per
share,  subject to the provision for adjustment  hereinafter set forth, equal to
100 times the aggregate  amount to be distributed per share to holders of shares
of Common  Stock,  or (B) to the holders of shares of stock  ranking on a parity
(either as to dividends or upon liquidation, dissolution or winding up) with the
Series A Preferred  Stock,  except  distributions  made  ratably on the Series A
Preferred  Stock and all such parity stock in proportion to the total amounts to
which the  holders  of all such  shares  are  entitled  upon  such  liquidation,
dissolution  or winding up. In the event the  Corporation  shall at any time (i)
declare a dividend on the  outstanding  shares of Common Stock payable in shares
of Common Stock,  (ii) subdivide the outstanding  shares of Common Stock,  (iii)
combine the outstanding shares of Common Stock in a smaller number of shares, or
(iv)  issue  any  shares  of its  capital  stock  in a  reclassification  of the
outstanding  shares of Common  Stock  (including  any such  reclassification  in
connection  with a  consolidation  or  merger in which  the  Corporation  is the
continuing or surviving corporation),  then, in each such case and regardless of
whether any shares of Series A Preferred  Stock are then issued or  outstanding,
the aggregate  amount to which each holder of shares of Series A Preferred Stock
would otherwise be entitled immediately prior to such event under the proviso in
clause (A) of the  preceding  sentence  shall be  adjusted by  multiplying  such
amount by a fraction,  the  numerator of which is the number of shares of Common
Stock  outstanding  immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding  immediately prior to
such event.

                        VII. 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 each such case, each share of Series A Preferred Stock shall
at the same time be  similarly  exchanged  or changed  into an amount per share,
subject to the  provision for  adjustment  hereinafter  set forth,  equal to 100
times the aggregate amount of stock, securities,  cash and/or any other property
(payable  in kind),  as the case may be,  into  which or for which each share of
Common Stock is changed or exchanged.  In the event the Corporation shall at any
time

                                      A-5
<PAGE>

(A)  declare a dividend on the  outstanding  shares of Common  Stock  payable in
shares of Common Stock,  (B) subdivide the  outstanding  shares of Common Stock,
(C)  combine  the  outstanding  shares  of Common  Stock in a smaller  number of
shares,  or (D) issue any shares of its capital stock in a  reclassification  of
the outstanding shares of Common Stock (including any such  reclassification  in
connection  with a  consolidation  or  merger in which  the  Corporation  is the
continuing or surviving corporation),  then, in each such case and regardless of
whether any shares of Series A Preferred  Stock are then issued or  outstanding,
the amount set forth in the  preceding  sentence with respect to the exchange or
change of shares of Series A Preferred  Stock  shall be adjusted by  multiplying
such amount by a  fraction,  the  numerator  of which is the number of shares of
Common Stock  outstanding  immediately  after such event and the  denominator of
which is the number of shares of Common Stock that were outstanding  immediately
prior to such event.

                                VIII. Redemption

     The shares of Series A Preferred Stock shall not be redeemable.

                                    IX. Rank

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

                                  X. Amendment

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

     3. These  amendments  were duly  adopted by the Board of  Directors  of the
Corporation on May 5, 1999 pursuant to Sections 607.0602 and 607.1002 of the Act
and shareholder  action is not required with respect to the amendments set forth
herein.

     4. The effective time and date of these Articles of Amendment shall be 5:00
p.m., Eastern time, on June 11, 1999.

                                RIGHT CERTIFICATE

                          FLORIDA ROCK INDUSTRIES, INC.

     This  certifies  that   ______________,   or  registered  assigns,  is  the
registered owner of the number of Rights set forth above, each of which entitles
the owner thereof, subject to the terms, provisions and conditions of the Rights

Rock Industries,  Inc., a Florida  corporation (the "Company"),  and First Union
National  Bank (the "Rights  Agent"),  to purchase  from the Company at any time
after the  Distribution  Date (as such term is defined in the Rights  Agreement)
and prior to 5:00 P.M.  (Eastern  time) on September  30, 2009 at the  principal
office  or  offices  of the  Rights  Agent  designated  for  such  purpose,  one
one-hundredth  of  a  fully  paid   nonassessable   share  of  Series  A  Junior
Participating  Preferred  Stock,  par  value  $.01  per  share  (the  "Preferred
Shares"), of the Company, at a Purchase Price of $145 per one one-hundredth of a
Preferred Share (the "Purchase Price"),  upon presentation and surrender of this
Right Certificate with the Form of Election to Purchase and related  Certificate
duly executed.  If this Right Certificate shall be exercised in part, the holder
shall be entitled to receive upon surrender hereof another Right  Certificate or
Right  Certificates for the number of whole Rights not exercised.  The number of
Rights evidenced by this Right Certificate (and the number of one one-hundredths
of a Preferred  Share which may be purchased  upon  exercise  thereof) set forth
above, and the Purchase Price set forth above, are the number and Purchase Price
as of June 11, 1999, based on the Preferred Shares as constituted at such date.

     As provided in the Rights Agreement,  the Purchase Price and the number and
kind of securities  issuable  upon the exercise of the Rights  evidenced by this
Right  Certificate  are  subject to  adjustment  upon the  happening  of certain

     This Right  Certificate  is subject  to all of the  terms,  provisions  and
conditions of the Rights Agreement,  which terms,  provisions and conditions are
hereby  incorporated  herein by  reference  and made a part  hereof and to which
Rights Agreement  reference is hereby made for a full description of the rights,
limitations of rights,  obligations,  duties and immunities of the Rights Agent,
the Company  and the holders of the Right  Certificates,  which  limitations  of
rights  include the  temporary  suspension of the  exercisability  of the Rights
under the circumstances specified in the Rights Agreement.  Copies of the Rights
Agreement are on file at the above-mentioned office of the Rights Agent.

     Pursuant  to  the  Rights  Agreement,  from  and  after  the  later  of the
Distribution  Date and the first  occurrence of a Flip-in Event (as such term is
defined in the Rights  Agreement),  (i) any Rights that are or were  acquired or
beneficially  owned by any  Acquiring  Person (or any  Affiliate or Associate of
such  Acquiring  Person)  shall  be void and any  holder  of such  Rights  shall
thereafter  have no right to exercise  such Rights  under any  provision  of the
Rights  Agreement,  (ii) no Right  Certificate  shall be issued  pursuant to the
Rights  Agreement  that  represents  Rights  beneficially  owned by an Acquiring
Person or any Affiliate or Associate  thereof,  (iii) no Right Certificate shall
be issued at any time upon the transfer of any Rights to an Acquiring  Person or
any Affiliate or Associate thereof or to any nominee of such Acquiring Person or
Affiliate or Associate thereof, and (iv) any Right Certificate  delivered to the
Rights Agent for transfer to an Acquiring  Person or any  Affiliate or Associate
thereof shall be cancelled.

     This Right Certificate,  with or without other Right  Certificates,  may be
transferred,  split up,  combined or exchanged for another Right  Certificate or
Right  Certificates,  entitling  the  holder to  purchase  a like  number of one
one-hundredths of a Preferred Share (or other securities, as the case may be) as
the Right Certificate or Right Certificates surrendered shall have entitled such
holder  (or  former  holder  in  the  case  of a  transfer)  to  purchase,  upon
presentation  and surrender  hereof at the principal  office of the Rights Agent
designated for such purpose,  with the Form of Assignment (if  appropriate)  and
the related Certificate duly executed.

     Subject to the provisions of the Rights Agreement,  the Rights evidenced by
this  Certificate  may be redeemed by the Company at its option at a  Redemption
Price of $0.01 per Right.  The Rights  Agreement may be supplemented and amended
by the Company, as provided therein.

     The Company is not required to issue  fractions of Preferred  Shares (other
than fractions which are integral  multiples of one one-hundredth of a Preferred
Share,  which may, at the option of the  Company,  be  evidenced  by  depositary
receipts) or other securities  issuable upon the exercise of any Right or Rights
evidenced hereby.  In lieu of issuing such fractional  Preferred Shares or other
securities,  the  Company  may make a cash  payment,  as  provided in the Rights
Agreement.

     No holder of this Right Certificate,  as such, shall be entitled to vote or
receive  dividends  or be deemed for any  purpose  the  holder of the  Preferred
Shares  or of any  other  securities  of the  Company  which  may at any time be
issuable upon the exercise of the

                                      B-2
<PAGE>

Right or Rights  represented  hereby,  nor shall anything contained herein or in
the Rights Agreement be construed to confer upon the holder hereof, as such, any
of the  rights  of a  shareholder  of the  Company  or any right to vote for the
election  of  directors  or upon any matter  submitted  to  shareholders  at any
meeting thereof,  or to give or withhold consent to any corporate  action, or to
receive notice of meetings or other actions  affecting  shareholders  (except as
provided  in the Rights  Agreement),  or to receive  dividends  or  subscription
rights,  or  otherwise,  until  the  Right or  Rights  evidenced  by this  Right
Certificate  shall have been exercised in accordance  with the provisions of the
Rights Agreement.

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

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES

Introduction

     On May 5, 1999,  the Board of Directors of Florida  Rock  Industries,  Inc.
(the  "Company")  declared a dividend of one preferred  share  purchase right (a
"Right") for each  outstanding  share of common stock, par value $.10 per share,
of the Company (the "Common  Shares").  The dividend is payable on June 11, 1999
(the "Record Date") to the  shareholders of record on that date. The description
and terms of the Rights are set forth in an Agreement (the "Agreement")  between
the Company and First Union National Bank as Rights Agent (the "Rights Agent").

Purchase Price

     Each Right entitles the registered  holder to purchase from the Company one
one-hundredth of a share of Series A Junior Participating Preferred Stock of the
Company, par value $.01 per share (the "Preferred  Shares"),  at a price of $145
per one  one-hundredth of a Preferred Share (the "Purchase  Price"),  subject to
adjustment.

Flip-In

     In the event that any Person or group of affiliated  or associated  Persons
acquires  beneficial  ownership of 15% or more of the outstanding  Common Shares
other than any Person or group of  affiliated  or  associated  Persons  who were
Beneficial Owners, individually or collectively, of 15% or more of the Company's
Common Shares outstanding on May 4, 1999 (an "Acquiring Person"), each holder of
a Right,  other than Rights  beneficially  owned by the Acquiring  Person (which
will  thereafter  be  void),  will  thereafter  have the right to  receive  upon
exercise  that number of Common  Shares  having a market  value of two times the
exercise  price of the  Right.  At any time prior to the  Distribution  Date (as
defined  below),  the Company's Board of Directors may declare that in lieu of a
cash payment,  the  registered  holder of a Right  Certificate  may exercise the
Rights (except as otherwise  provided herein) in whole or in part upon surrender
of the Right  Certificate  with an  election to  exercise  such  Rights  without
payment of cash.  A holder who elects to make a cashless  exercise  will receive
the number of Common Shares having a value equal to the Purchase Price.

Flip-Over

     If the  Company  is  acquired  in a merger  or other  business  combination
transaction or 50% or more of its consolidated  assets or earning power are sold
after a Person or group has become an Acquiring  Person,  each holder of a Right
(other than Rights  beneficially owned by Acquiring Person,  which will be void)
will thereafter have the right

                                      C-1
<PAGE>

to receive that number of shares of common stock of the issuer which at the time
of such  transaction will have a market value of two times the exercise price of
the Right. At any time prior to the  Distribution  Date (as defined below),  the
Company's  Board of Directors  may declare that in lieu of a cash  payment,  the
registered  holder of a Right  Certificate  may exercise  the Rights  (except as
otherwise  provided  herein)  in whole or in part  upon  surrender  of the Right
Certificate  with an election to exercise such Rights without payment of cash. A
holder who elects to make a cashless  exercise will receive the number of shares
of common stock of the Issuer having a value equal to the Purchase Price.

Distribution Date

     The Distribution Date is the earlier of

     (i) The Close of  Business  on the tenth  Business  Day  following a public
announcement  that a Person or group of affiliated  or  associated  Persons have
acquired  beneficial  ownership of 15% or more of the outstanding Common Shares;
or

     (ii) The Close of Business on the tenth Business Day (or such later date as
may be  determined  by action of the Board of Directors  of the Company,  if the
Distribution Date shall have previously occurred) following the commencement of,
or  announcement  of an intention to make, a tender offer or exchange  offer the
consummation  of which would result in the  beneficial  ownership by a Person or
group of 15% or more of the outstanding Common Shares.

Transfer and Detachment

     Until the Distribution Date, the Rights will be evidenced,  with respect to
any of the Common Share certificates  outstanding as of the Record Date, by such
Common Share certificate with a copy of this Summary of Rights attached thereto.
Until the Distribution Date (or earlier redemption or expiration of the Rights),
the  Rights  will be  transferred  with and only  with the  Common  Shares,  and
transfer of those certificates will also constitute transfer of these Rights.

     As  soon  as  practicable   following  the  Distribution   Date,   separate
certificates  evidencing  the Rights  ("Right  Certificates")  will be mailed to
holders  of record of the  Common  Shares  as of the  Close of  Business  on the
Distribution  Date and such separate Right  Certificates  alone will  thereafter
evidence the Rights.

Exercisability

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on September  30, 2009 (the "Final  Expiration  Date"),  unless the Final
Expiration  Date is  extended  or unless  the  Rights are  earlier  redeemed  or
exchanged by the Company, in each case, as described below.

                                      C-2

Adjustments

     The Purchase  Price  payable,  and the number of Preferred  Shares or other
securities  or  property  issuable,  upon  exercise of the Rights are subject to
adjustment  from  time  to  time to  prevent  dilution  in the  event  of  stock
dividends,  stock  splits,  reclassifications,  or  certain  distributions  with
respect to the Preferred Shares. The number of outstanding Rights and the number
of one  one-hundredths of a Preferred Share issuable upon exercise of each Right
are also subject to adjustment if, prior to the  Distribution  Date,  there is a
stock  split of the  Common  Shares or a stock  dividend  on the  Common  Shares
payable in Common Shares or subdivisions,  consolidations or combinations of the
Common Shares. With certain exceptions, no adjustment in the Purchase Price will
be required until cumulative adjustments require an adjustment of at least 1% in
such Purchase  Price.  No fractional  Preferred Share will be issued (other than
fractions  which are  integral  multiples  of one  one-hundredth  of a Preferred
Share,  which may, at the  election of the Company,  be evidenced by  depositary
receipts) and, in lieu thereof,  an adjustment in cash will be made based on the
market price of the Preferred Share on the last Trading Day prior to the date of
exercise.

Preferred Shares

     Preferred  Share  purchasable  upon  exercise  of the  Rights  will  not be
redeemable.  Each Preferred  Share will be entitled to, if declared by the Board
of Directors,  a minimum preferential quarterly dividend payment of $1 per share
but will be entitled to an aggregate dividend of 100 times the dividend declared
per Common  Share.  In the event of  liquidation,  the holders of the  Preferred
Share will be entitled to a minimum preferential liquidation payment of $100 per
share but will be entitled to an aggregate payment of 100 times the payment made
per Common Share. Each Preferred Share will have 100 votes, voting together with
the Common Shares.  Finally, in the event of any merger,  consolidation or other
transaction in which Common Shares are exchanged,  each Preferred  Share will be
entitled to receive 100 times the amount received per Common Share. These rights
are protected by customary antidilution provisions.

     The  value  of  the  one  one-hundredth   interest  in  a  Preferred  Share
purchasable  upon  exercise of each Right  should,  because of the nature of the
Preferred Share dividend,  liquidation and voting rights,  approximate the value
of one Common Share.

Exchange

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

                                      C-3
<PAGE>

Redemption

     At any time prior to the  Expiration  Date,  the Board of  Directors of the
Company may redeem the Rights in whole,  but not in part, at a price of $.01 per
Right  (the  "Redemption  Price").  The  redemption  of the  Rights  may be made
effective  at such  time on such  basis  with  such  conditions  as the Board of
Directors in its sole discretion may establish.  Immediately upon any redemption
of the Rights,  the right to exercise  the Rights  will  terminate  and the only
right of the holders of Rights will be to receive the Redemption Price.

Amendments

     The Rights  Agreement may be amended by the Company without the approval of
any holders of Right Certificates,  including  amendments which add other events
requiring  adjustment to the Purchase  Price payable and the number of Preferred
Shares or other  securities  issuable  upon the  exercise of the Rights or which
modify  procedures  relating to the  redemption of the Rights,  provided that no
amendment may be made which decreases the stated  Redemption Price or the period
of time  remaining  until the Final  Expirations  Date or which  modifies a time
period  relating  to when the Rights may be  redeemed at such time as the Rights
are not then redeemable.

Rights and Holders

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

Further Information

     A copy of the Agreement is available free of charge from the Company.  This
summary  description  of the  Rights  does not  purport  to be  complete  and is
qualified  in its  entirety  by  reference  to the  Agreement,  which is  hereby
incorporated herein by reference.
