ITEM 5.           OTHER EVENTS.
                  ------------

I.       Rights Plan

         The  Board  of  Directors  of  DALLAS  SEMICONDUCTOR  CORPORATION  (the
"Company")  has declared a dividend of one  preferred  share  purchase  right (a
"Right") for each  outstanding  share of common stock, par value $.02 per share,
of the Company (the "Common  Stock").  The dividend is payable on September  21,
1999 (the "Record Date") to the  stockholders of record on that date. Each Right
entitles the registered  holder to purchase from the Company one  one-thousandth
of a share of Series A Junior Participating  Preferred Stock, par value $.10 per
share,  of the  Company  (the  "Preferred  Stock")  at a price  of $250  per one
one-thousandth of a share of Preferred Stock (the "Purchase Price"),  subject to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement  dated as of September  10, 1999, as the same may be amended from time
to  time  (the  "Rights   Agreement"),   between  the  Company  and  CHASEMELLON
SHAREHOLDER SERVICES, L.L.C., as Rights Agent (the "Rights Agent").

         Detachment  of Rights:  Exercise.  Until the earlier to occur of (i) 10
days  following a public  announcement  that a person or group of  affiliated or
associated persons (with certain exceptions, an "Acquiring Person") has acquired
beneficial ownership of 15% or more of the outstanding shares of Common Stock or
(ii) 10 business  days (or such later date as may be determined by action of the
Board of  Directors  prior to such  time as any  person  or group of  affiliated
persons  becomes  an  Acquiring   Person)  following  the  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  shares of Common Stock (the earlier of
such dates being called the "Distribution  Date"), the Rights will be evidenced,
with  respect  to any of the Common  Stock  certificates  outstanding  as of the
Record  Date,  by such  Common  Stock  certificate  together  with a copy of the
Summary of Rights in substantially the form of Exhibit C to the Rights Agreement
(the "Summary of Rights").

         The Rights Agreement  provides that,  until the  Distribution  Date (or
earlier expiration of the Rights),  the Rights will be transferred with and only
with the Common Stock. Until the Distribution Date (or earlier expiration of the
Rights),  new  Common  Stock  certificates  issued  after the  Record  Date upon
transfer or new issuances of Common Stock will contain a notation  incorporating
the Rights  Agreement  by  reference.  Until the  Distribution  Date (or earlier
expiration of the Rights),  the surrender for transfer of any  certificates  for
shares of Common  Stock  outstanding  as of the Record  Date,  even without such
notation or a copy of the Summary of Rights,  will also  constitute the transfer
of the Rights  associated  with the shares of Common Stock  represented  by such
certificates.  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  Stock as of the  close of  business  on the
Distribution Date and such separate Right  Certificates  alone will evidence the
Rights.

         The Rights are not exercisable until the Distribution  Date. The Rights
will expire on September 9, 2009 (the "Final Expiration Date"), unless the Final
Expiration Date is advanced




                                        2

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

         If any person or group of affiliated or associated  persons  becomes an
Acquiring Person,  each holder of a Right, other than Rights  beneficially owned
by the Acquiring Person (which will thereupon become void), will thereafter have
the right to receive  upon  exercise  of a Right that number of shares of Common
Stock having a market value of two times the exercise price of the Right.

         If, after a person or group has become an Acquiring Person, 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, proper provisions will be
made so that each holder of a Right (other than Rights  beneficially owned by an
Acquiring  Person which will have become void) will thereafter have the right to
receive  upon the  exercise of a Right that number of shares of common  stock of
the person with whom the Company has engaged in the  foregoing  transaction  (or
its  parent)  that at the time of such  transaction  have a market  value of two
times the exercise price of the Right.

         At any time after any person or group  becomes an Acquiring  Person and
prior to the earlier of one of the events described in the previous paragraph or
the  acquisition  by such  Acquiring  Person  of 50% or more of the  outstanding
shares of Common  Stock,  the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such Acquiring  Person which will have become
void),  in whole or in part, for shares of Common Stock or Preferred Stock (or a
series of the Company's  preferred stock having equivalent  rights,  preferences
and  privileges),  at an  exchange  ratio of one  share of  Common  Stock,  or a
fractional  share of Preferred  Stock (or other preferred  stock)  equivalent in
value thereto, per Right.

         Preferred  Shares.  Shares of Preferred Stock purchasable upon exercise
of the Rights  will not be  redeemable.  Each share of  Preferred  Stock will be
entitled,  when, as and if declared, to a dividend payment per share equal to an
aggregate  dividend  of 1000  times the  dividend  declared  per share of Common
Stock.  Upon the  liquidation,  dissolution  or winding up of the  Company,  the
holders  of the  Preferred  Stock  will be  entitled  to a minimum  preferential
payment of $1.00 per share (plus any accrued but unpaid  dividends)  but will be
entitled to an  aggregate  payment of 1000 times the  payment  made per share of
Common  Stock.  Each  share of  Preferred  Stock  will have 1000  votes,  voting
together with the Common Stock. Finally, upon any merger, consolidation or other
transaction  in which  outstanding  shares of  Common  Stock  are  converted  or
exchanged,  each share of Preferred Stock will be entitled to receive 1000 times
the amount  received per share of Common  Stock.  These Rights are  protected by
customary antidilution provisions.

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

         The offer and sale of the Preferred  Shares or Common  Shares  issuable
upon exercise of the Rights will be registered pursuant to the Securities Act of
1933, as amended;  such  registration will not become effective until the Rights
become exercisable.

         Antidilution and Other Adjustments.  The number of one  one-thousandths
of a Preferred Share or other  securities or property  issuable upon exercise of
the Rights, and the Purchase Price payable, are subject to customary adjustments
from time to time to prevent dilution.

         Redemption  of  Rights.  At any time  prior to the  earlier  of (i) the
Distribution  Date or (ii) the Final  Expiration Date, the Board of Directors of
the Company may redeem all but not less than all of the then outstanding  Rights
at a price of $0.01 per Right (the  "Redemption  Price").  The redemption of the
Rights  may be made  effective  at  such  time,  on such  basis  and  with  such
conditions as the Board of Directors in its sole  discretion may  establish.  At
the  effective  time of such  redemption,  the right to exercise the Rights will
terminate  and the only right of the  holders of Rights  will be to receive  the
Redemption Price.

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

         Amendment of Rights. For so long as the Rights are then redeemable, the
Company  may,  except with  respect to the  redemption  price,  amend the Rights
Agreement in any manner. After the Rights are no longer redeemable,  the Company
may, except with respect to the redemption price,  amend the Rights Agreement in
any  manner  that does not  adversely  affect  the  interests  of holders of the
Rights.

         This summary  description of the Rights does not purport to be complete
and is qualified in its  entirety by  reference  to the Rights  Agreement  filed
herewith as Exhibit 1, which is hereby incorporated by reference.

                                RIGHTS AGREEMENT
                                ----------------


         Rights Agreement, dated as of September 10, 1999 ("Agreement"), between
DALLAS SEMICONDUCTOR  CORPORATION,  a Delaware corporation (the "Company"),  and
CHASEMELLON  SHAREHOLDER  SERVICES,  L.L.C.,  a  New  Jersey  limited  liability
company, as Rights Agent (the "Rights Agent").

         The Board of  Directors  of the Company has  authorized  and declared a
dividend of one  preferred  share  purchase  right (a "Right") for each share of
Common Stock (as hereinafter defined) of the Company outstanding as of the Close
of Business (as defined below) on September 21, 1999 (the "Record  Date"),  each
Right  representing  the  right  to  purchase  one  one-thousandth  (subject  to
adjustment) of a share of Preferred  Stock (as  hereinafter  defined),  upon the
terms and subject to the conditions herein set forth, and has further authorized
and  directed  the  issuance  of one Right  (subject to  adjustment  as provided
herein) with respect to each share of Common Stock that shall become outstanding
between  the  Record  Date  and the  earlier  of the  Distribution  Date and the
Expiration Date (as such terms are hereinafter defined); provided, however, that
Rights may be issued with  respect to shares of Common  Stock that shall  become
outstanding  after the  Distribution  Date and prior to the  Expiration  Date in
accordance with SECTION 22.

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

         SECTION 1.  CERTAIN DEFINITIONS.  For  purposes of  this Agreement, the
following terms have the meaning indicated:

          (a)  "Acquiring  Person"  shall  mean  any  Person  (as  such  term is
               hereinafter  defined) who or which shall be the Beneficial  Owner
               (as  such  term  is  hereinafter  defined)  of 15% or more of the
               shares of Common  Stock then  outstanding,  but shall not include
               (i) an Exempt  Person (as such term is  hereinafter  defined)  or
               (ii) any such  Person who has  reported  or is required to report
               such  ownership  (but less than 25% ) on  Schedule  13G under the
               Securities Exchange Act of 1934, as amended (the "Exchange Act"),
               (or any comparable or successor  report) or on Schedule 13D under
               the Exchange Act (or any comparable or successor  report),  which
               Schedule 13D  (including  an amendment to Schedule  13D) does not
               state  any  intention  to or  reserve  the  right to  control  or
               influence the  management or policies of the Company or engage in
               any of the  actions  specified  in  Item 4 of such  Schedule  13D
               (other than the  disposition of the Common Stock) and,  within 10
               Business  Days (as such  term is  hereinafter  defined)  of being
               requested  by the  Company  to  advise  it  regarding  the  same,
               certifies  to the  Company  that such Person  acquired  shares of
               Common  Stock  in  excess  of  14.99%  inadvertently  or  without
               knowledge  of the  effect  of the  terms of the  Rights  and who,
               together with all Affiliates and Associates,  thereafter does not
               acquire  additional  shares of Common Stock while the  Beneficial
               Owner of 15% or more of the shares of Common Stock then


                                        1

<PAGE>



               outstanding;  provided, however, that (A) if the Person requested
               to so certify  fails to do so within 10  Business  Days or (B) if
               such Person  thereafter  becomes obligated to file a Schedule 13D
               (including  an amendment to a Schedule  13D) that would state any
               intention  to or reserve  the right to control or  influence  the
               management  or  policies  of the  Company or engage in any of the
               actions  specified in Item 4 of such Schedule 13D (other than the
               disposition of the Common  Stock),  then such Person shall become
               an Acquiring Person immediately  thereafter.  Notwithstanding the
               foregoing,  (x) if,  as of the date  hereof,  any  Person  is the
               Beneficial  Owner of 15% or more of the  shares of  Common  Stock
               outstanding,  such  Person  shall not be or become an  "Acquiring
               Person"  unless and until such time as such Person  shall  become
               the Beneficial  Owner of an additional 1% of the shares of Common
               Stock (other than pursuant to a dividend or distribution  paid or
               made by the Company on the outstanding  Common Stock in shares of
               Common  Stock  or  pursuant  to a  split  or  subdivision  of the
               outstanding Common Stock),  unless,  upon becoming the Beneficial
               Owner of such  additional  shares of Common  Stock,  either  such
               Person  is not  then the  Beneficial  Owner of 15% or more of the
               shares  of  Common  Stock  then  outstanding  or such  Person  is
               exempted from the  definition of "Acquiring  Person"  pursuant to
               SECTION  1(A)(II)  hereof  and  (y) no  Person  shall  become  an
               "Acquiring  Person" as the result of an  acquisition of shares of
               Common  Stock by the Company  which,  by  reducing  the number of
               shares outstanding,  increases the proportionate number of shares
               of Common Stock  beneficially owned by such Person to 15% or more
               of  the  shares  of  Common  Stock  then  outstanding;  provided,
               however,  that if a Person shall become the  Beneficial  Owner of
               15% or more of the  shares of Common  Stock then  outstanding  by
               reason  of such  share  acquisitions  by the  Company  and  shall
               thereafter  become the Beneficial Owner of any additional  shares
               of  Common   Stock   (other  than   pursuant  to  a  dividend  or
               distribution  paid  or  made by the  Company  on the  outstanding
               Common  Stock in shares of Common Stock or pursuant to a split or
               subdivision of the  outstanding  Common Stock),  then such Person
               shall be deemed to be an "Acquiring Person" unless, upon becoming
               the Beneficial  Owner of such additional  shares of Common Stock,
               either  such  Person is not then the  Beneficial  Owner of 15% or
               more of the  shares  of Common  Stock  then  outstanding  or such
               Person is exempted  from the  definition  of  "Acquiring  Person"
               pursuant to SECTION  1(A)(II)  hereof.  For all  purposes of this
               Agreement,  any  calculation  of the  number  of shares of Common
               Stock outstanding at any particular time,  including for purposes
               of  determining  the  particular  percentage of such  outstanding
               shares of  Common  Stock of which  any  Person is the  Beneficial
               Owner, shall be made in accordance with the last sentence of Rule
               13d-3(d)(1)(i)  of the General  Rules and  Regulations  under the
               Exchange Act as in effect on the date hereof.

          (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
               hereof.

of such  Person or any of such  Person's  Affiliates  or  Associates  until such
tendered securities are accepted for purchase,  (y) securities which such Person

Ownership" of or to  "beneficially  own" any securities  that are  "beneficially
owned" (as defined in this SECTION 1(C)),  including,  without limitation,  in a

               Stock   aggregating   15%  or  more  of  the  Common  Stock  then

               such  dates  occurs  after the date of this  Agreement  and on or
               prior to the Record Date, then the Distribution Date shall be the

               provisions of SECTION 3(B) hereof) by the certificates for Common
               Stock  registered in the names of the holders  thereof and not by

               transferable  only in  connection  with the  transfer  of  Common
               Stock. As soon as practicable  after the  Distribution  Date, the
               Company  will   prepare  and  execute,   the  Rights  Agent  will
               countersign  and the  Company  will send or cause to be sent (and
               the  Rights  Agent  will,  if  requested,  send) by  first-class,
               insured,  postage-prepaid  mail,  to each record holder of Common

               Acquiring  Person),  at the address of such  holder  shown on the
               records of the Company, a Right Certificate, in substantially the
               form of EXHIBIT B hereto (a "Right Certificate"),  evidencing one
               Right  (subject to adjustment as provided  herein) for each share
               of Common Stock so held. As of the Distribution  Date, the Rights
               will be evidenced solely by such Right Certificates.

          (b)  On the Record Date,  or as soon as  practicable  thereafter,  the

               Shares of Preferred Stock, in substantially the form of EXHIBIT C
               hereto  (the  "Summary  of  Rights"),  by  first-class,  postage-
               prepaid  mail,  to each record  holder of Common  Stock as of the
               Close of Business  on the Record  Date (other than any  Acquiring
               Person or any Associate or Affiliate of any Acquiring Person), at
               the address of such holder  shown on the records of the  Company.
               With respect to certificates  for Common Stock  outstanding as of
               the Record Date, until the Distribution  Date, the Rights will be
               evidenced by such


                                        6

<PAGE>



                  certificates  registered  in the names of the holders  thereof
                  together  with the Summary of Rights.  Until the  Distribution
                  Date (or, if earlier,  the Expiration Date), the surrender for
                  transfer of any  certificate  for Common Stock  outstanding on
                  the  Record  Date,  with or  without a copy of the  Summary of
                  Rights,  shall  also  constitute  the  transfer  of the Rights
                  associated with the Common Stock represented thereby.

         (c)      Certificates  issued  for  Common  Stock  (including,  without
                  limitation,   upon  transfer  of  outstanding   Common  Stock,
                  disposition  of Common Stock out of treasury stock or issuance
                  or reissuance  of Common Stock out of authorized  but unissued
                  shares)  after the Record Date but prior to the earlier of the
                  Distribution Date and the Expiration Date shall have impressed
                  on,  printed on,  written on or otherwise  affixed to them the
                  following legend:

                  This certificate also evidences and entitles the holder hereof
                  to  certain  rights  ("Rights")  as  set  forth  in  a  Rights
                  Agreement  between  DALLAS   SEMICONDUCTOR   CORPORATION  (the
                  "Company") and CHASEMELLON  SHAREHOLDER  SERVICES,  L.L.C., as
                  Rights Agent,  dated as of September 10, 1999, as the same may
                  be amended  from time to time (the  "Rights  Agreement"),  the
                  terms of which are hereby incorporated herein by reference and
                  a copy of which is on file at the principal  executive offices
                  of the Company. Under certain  circumstances,  as set forth in
                  the Rights Agreement such Rights will be evidenced by separate
                  certificates   and  will  no  longer  be   evidenced  by  this
                  certificate.  The  Company  will  mail to the  holder  of this
                  certificate  a copy of the  Rights  Agreement  without  charge
                  after  receipt of a written  request  therefor.  Under certain
                  circumstances,  as set forth in the Rights  Agreement,  Rights
                  owned by or  transferred  to any  Person  who is or becomes an
                  Acquiring  Person (as  defined in the  Rights  Agreement)  and
                  certain transferees thereof will become null and void and will
                  no longer be transferable.

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

         Notwithstanding  this paragraph (c), the omission of a legend shall not
affect the  enforceability  of any part of this  Agreement  or the rights of any
holder of the Rights.

         SECTION 4. FORM OF RIGHT CERTIFICATES.  The Right Certificates (and the
forms of  election  to purchase  shares and of  assignment  to be printed on the
reverse  thereof)  shall be  substantially  in the form set  forth in  EXHIBIT B
hereto  and may  have  such  marks of  identification  or  designation  and such
legends,  summaries  or  endorsements,  printed  thereon as the Company may deem
appropriate and as are not  inconsistent  with the provisions of this Agreement,
or as may be  required  to comply  with any  applicable  law or with any rule or
regulation  made  pursuant  thereto or with any rule or  regulation of any stock
exchange or  interdealer  quotation  system on which the Rights may from time to
time be listed or quoted,  or to conform to usage.  Subject to the provisions of
SECTIONS 11, 13 and 22 hereof,  the Right Certificates shall entitle the holders
thereof to purchase such number of one one-  thousandths of a share of Preferred
Stock as shall be set forth  therein  at the price per one  one-thousandth  of a
share of Preferred  Stock set forth  therein  (the  "Purchase  Price"),  but the
number  of such  one  one-thousandths  of a share  of  Preferred  Stock  and the
Purchase Price 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 the  President  of the  Company or any other  duly  authorized
               officer, either manually or by facsimile signature,  and shall be
               attested by the 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 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  Agreement  any  such  Person  was not such an
               officer.

          (b)  Following the  Distribution  Date,  the Rights Agent will keep or
               cause to be kept,  at an  office or  agency  designated  for such
               purpose,  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.

               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)  Subject to the  provisions of SECTION  11(A)(II)  hereof,  at any

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

               Certificate.

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

          (e)  Notwithstanding  anything  in  this  Agreement  to the  contrary,
               neither the Rights  Agent nor the Company  shall be  obligated to
               undertake any action with respect to a


                                       10

                  registered  holder  of  Rights  upon  the  occurrence  of  any
                  purported transfer or exercise of Rights pursuant to SECTION 6
                  hereof or this SECTION 7 unless such  registered  holder shall
                  have (i) completed and signed the Certificate contained in the
                  form of  assignment  or form of election to purchase set forth
                  on the reverse side of the Rights Certificate  surrendered for
                  such transfer or exercise and (ii)  provided  such  additional
                  evidence of the  identity of the  Beneficial  Owner (or former
                  Beneficial  Owner)  thereof as the  Company  shall  reasonably
                  request.

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

         SECTION 9.  AVAILABILITY OF SHARES OF PREFERRED STOCK.

          (a)  The  Company  covenants  and  agrees  that  it will  cause  to be
               reserved and kept  available out of its  authorized  and unissued
               shares of Preferred  Stock or any shares of Preferred  Stock held
               in its  treasury;  the number of shares of  Preferred  Stock that
               will  be  sufficient  to  permit  the  exercise  in  full  of all
               outstanding Rights.

          (b)  So long as the  shares  of  Preferred  Stock  issuable  upon  the
               exercise  of Rights may be listed or  admitted  to trading on any
               national  securities  exchange,  or quoted on NASDAQ, the Company
               shall use its best efforts to cause,  from and after such time as
               the  Rights  become  exercisable,  all shares  reserved  for such
               issuance to be listed or admitted to trading on such exchange, or
               quoted on NASDAQ,  upon  official  notice of  issuance  upon such
               exercise.

          (c)  From and after such time as the Rights  become  exercisable,  the
               Company shall use its best efforts,  if then  necessary to permit
               the  issuance of shares of  Preferred  Stock upon the exercise of
               Rights,  to register and qualify  such shares of Preferred  Stock
               under the Securities Act and any applicable  state  securities or
               "Blue  Sky"  laws (to the  extent  exemptions  therefrom  are not
               available),  cause such registration statement and qualifications
               to become  effective  as soon as  possible  after such filing and
               keep such  registration  and  qualifications  effective until the
               earlier  of the  date  as of  which  the  Rights  are  no  longer
               exercisable  for such  securities  and the  Expiration  Date. The
               Company  may  temporarily  suspend,  for a period  of time not to
               exceed  90 days,  the  exercisability  of the  Rights in order to
               prepare and file a registration statement under


                                       11

<PAGE>



               the  Securities Act and 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.  Notwithstanding
               any provision of this Agreement to the contrary, the Rights shall
               not be  exercisable  in any  jurisdiction  unless  the  requisite
               qualification in such  jurisdiction  shall have been obtained and
               until a  registration  statement  under  the  Securities  Act (if
               required) shall have been declared effective.

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

          (e)  The Company  further  covenants  and agrees that it will pay when
               due and payable any and all federal and state  transfer taxes and
               charges  that  may be  payable  in  respect  of the  issuance  or
               delivery of the Right  Certificates or of any shares of Preferred
               Stock  upon the  exercise  of  Rights.  The  Company  shall  not,
               however,  be required to pay any transfer tax that may be payable
               in respect of any transfer or delivery of Right Certificates to a
               Person other than, or the issuance or delivery of certificates or
               depositary  receipts for the Preferred Stock in a name other than
               that  of,  the  registered   holder  of  the  Right   Certificate
               evidencing Rights surrendered for exercise or to issue or deliver
               any certificates or depositary  receipts for Preferred Stock upon
               the  exercise  of any  Rights  until any such tax shall have been
               paid (any such tax being  payable  by that  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.

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

         SECTION 11. ADJUSTMENT OF PURCHASE PRICE; NUMBER AND KIND OF SHARES AND
NUMBER OF RIGHTS. The Purchase Price, the number of shares of Preferred Stock or
other  securities  or property  purchasable  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) If the  Company  shall  at any  time  after  the date of this
               Agreement (A) declare and pay a dividend on the  Preferred  Stock
               payable  in  shares  of  Preferred   Stock,   (B)  subdivide  the
               outstanding   Preferred   Stock,   (C)  combine  the  outstanding
               Preferred  Stock  into a smaller  number  of shares of  Preferred
               Stock  or  (D)  issue  any  shares  of  its  capital  stock  in a
               reclassification  of the  Preferred  Stock  (including  any  such
               reclassification  in connection with a consolidation or merger in
               which the Company is the  continuing  or surviving  corporation),
               except as otherwise  provided in this SECTION 11(A), the Purchase
               Price in effect at the time of the record date for such  dividend
               or of the  effective  date of such  subdivision,  combination  or
               reclassification,  and the  number  and kind of shares of capital
               stock issuable on such date, shall be proportionately adjusted so
               that the holder of any Right  exercised  after such time shall be
               entitled  to receive the  aggregate  number and kind of shares of
               capital stock that, if such Right had been exercised  immediately
               prior  to  such  date  and at a time  when  the  Preferred  Stock
               transfer  books of the Company  were open,  the holder would have
               owned upon such  exercise and been  entitled to receive by virtue
               of such dividend,  subdivision,  combination or reclassification;
               provided,  however,  that in no event shall --------  ------- the
               consideration  to be paid upon the  exercise of one Right be less
               than the  aggregate  par value of the shares of capital  stock of
               the Company issuable upon exercise of one Right.

                  (ii)  Subject to SECTION 24 of this  Agreement,  if any Person
becomes an Acquiring  Person (the first  occurrence of such event being referred
to  hereinafter  as the "Flip-In  Event"),  then (A) the Purchase Price shall be
adjusted to be the  Purchase  Price in effect  immediately  prior to the Flip-In
Event  multiplied by the number of one  one-thousandths  of a share of Preferred
Stock for which a Right was exercisable immediately prior to such Flip-In Events
whether or not such Right was then exercisable,  and (B) each holder of a Right,
except as otherwise  provided in this SECTION  11(A)(II) and SECTION  11(A)(III)
hereof,  shall thereafter have the right to receive,  upon exercise thereof at a
price equal to the Purchase Price (as so adjusted), in accordance with the terms
of this  Agreement  and in lieu of shares of  Preferred  Stock,  such  number of
shares of Common  Stock as shall  equal the  result  obtained  by  dividing  the
Purchase  Price (as so adjusted) by 50% of the current per share market place of
the Common Stock  (determined  pursuant to SECTION  11(D) hereof) on the date of
such Flip- In Event; provided, however, that the Purchase Price (as so adjusted)
and the number of shares of Common Stock so receivable  upon exercise of a Right
shall,  following  the  Flip-In  Event,  be  subject to  further  adjustment  as
appropriate in accordance with SECTION 11(F) hereof. Notwithstanding anything in
this Agreement to the contrary,  however, from and after the Flip-in-Event,  any
Rights that are beneficially owned by (x) any Acquiring Person (or any Affiliate
or Associate of any Acquiring Person),  (y) a transferee of any Acquiring Person
(or any such Affiliate or Associate) who becomes a transferee  after the Flip-In
Event or (z) a transferee of any Acquiring Person (or any such Affiliate


                                       13

<PAGE>



or Associate) who became a transferee prior to or concurrently  with the Flip-In
Event pursuant to either (I) a transfer from the Acquiring  Person to holders of
its  equity  securities  or to  any  Person  with  whom  it has  any  continuing
agreement, arrangement or understanding regarding the transferred Rights or (II)
a  transfer  that the Board of  Directors  has  determined  is part of the plan,
arrangement  or  understanding  which has the purpose or effect of avoiding  the
provisions of this paragraph and subsequent  transferees of such Persons,  shall
be void  without  any  further  action  and any  holder  of  such  Rights  shall
thereafter  have no rights  whatsoever  with  respect to such  Rights  under any
provision of this  Agreement.  The Company shall use all  reasonable  efforts to
ensure that the  provisions  of this SECTION  11(A)(II) are complied  with,  but
shall have no liability to any holder of Right Certificates or other Person as a
result of its failure to make any  determinations  with  respect to an Acquiring
Person or its Affiliates,  Associates or transferees  hereunder.  From and after
the Flip- In Event, no Right  Certificate  shall be issued pursuant to SECTION 3
or SECTION 6 hereof that represents Rights that are or have become void pursuant
to the provisions of this paragraph and any Right  Certificate  delivered to the
Rights Agent that represents Rights that are or have become void pursuant to the
provisions of this paragraph shall be canceled. From and after the occurrence of
an event specified in SECTION 13(A) hereof, any Rights that theretofore have not
been  exercised   pursuant  to  this  SECTION   11(A)(II)  shall  thereafter  be
exercisable  only in accordance with SECTION 13 and not pursuant to this SECTION
11(A)(II).

                  (iii) The Company may at its option  substitute for a share of
Common  Stock  issuable  upon the  exercise  of  Rights in  accordance  with the
foregoing  subparagraph  (ii) a number of shares of Preferred  Stock or fraction
thereof  such that the current per share  market price of one share of Preferred
Stock  multiplied  by such  number or fraction is equal to the current per share
market  price of one share of Common  Stock.  If there  shall not be  sufficient
shares of Common Stock issued but not  outstanding or authorized but unissued to
permit the  exercise  in full of the  Rights in  accordance  with the  foregoing
subparagraph  (ii),  the Board of Directors  shall,  to the extent  permitted by
applicable law and any material  agreements  then in effect to which the Company
is a party (A) determine the excess (such excess, the "Spread") of (1) the value
of the  shares  of  Common  Stock  issuable  upon  the  exercise  of a Right  in
accordance with the foregoing  subparagraph  (ii) (the "Current Value") over (2)
the Purchase  Price (as adjusted in accordance  with the foregoing  subparagraph
(ii)),  and (B) with  respect to each Right  (other than Rights that have become
void pursuant to the foregoing  subparagraph  (ii)), make adequate  provision to
substitute  for the  shares of Common  Stock  issuable  in  accordance  with the
foregoing  subparagraph  (ii) upon  exercise  of the Right  and  payment  of the
Purchase Price (as adjusted in accordance therewith),  (1) cash, (2) a reduction
in such Purchase Price, (3) shares of Preferred Stock or other equity securities
of the Company (including,  without limitation, shares or fractions of shares of
preferred  stock  that,  by virtue of having  dividend,  voting and  liquidation
rights  substantially  comparable  to those of the shares of Common  Stock,  are
deemed in good faith by the Board of  Directors to have  substantially  the same
value as the shares of Common Stock (such  shares of Preferred  Stock and shares
or fractions of shares of Preferred Stock are hereinafter referred to as "Common
Stock  Equivalents")),  (4) debt securities of the Company, (5) other assets, or
(6) any  combination  of the foregoing,  having a value that,  when added to the
value of the shares of Common  Stock issued upon  exercise of such Right,  shall
have an  aggregate  value  equal to the  Current  Value  (less the amount of any
reduction in such Purchase Price), where such


                                       14

<PAGE>



aggregate value has been determined by the Board of Directors upon the advice of
a nationally  recognized  investment  banking firm selected in good faith by the
Board of  Directors;  provided,  however,  that if the  Company  shall  not make
adequate  provision to deliver value  pursuant to clause (B) above within thirty
(30) days following the Flip-In Event (the "Section  11(a)(ii)  Trigger  Date"),
then the Company  shall be  obligated  to deliver,  to the extent  permitted  by
applicable law and any material agreement then in effect to which the Company is
a party,  upon the  surrender  for  exercise  of a Right and  without  requiring
payment  of  such  Purchase  Price,  shares  of  Common  Stock  (to  the  extent
available),  and then,  if  necessary,  such  number or  fractions  of shares of
Preferred Stock (to the extent  available) and then, if necessary,  cash,  which
shares  and/or cash have an  aggregate  value equal to the Spread.  If, upon the
occurrence of the Flip-In Event,  the Board of Directors shall determine in good
faith that it is likely that sufficient  additional shares of Common Stock could
be authorized  for issuance  upon  exercise in full of the Rights,  then, if the
Board of Directors so elects,  the thirty (30) day period set forth above may be
extended to the extent  necessary,  but not more than ninety (90) days after the
Section  11(a)(ii)  Trigger Date, in order that the Company may seek stockholder
approval for the  authorization of such additional  shares (such thirty (30) day
period, as it may be extended,  is herein called the "Substitution  Period"). To
the extent that the Company  determines  that some action need be taken pursuant
to the second and/or third sentence of this SECTION 11(A)(III),  the Company (x)
shall provide, subject to SECTION 11(A)(II) hereof and the last sentence of this
SECTION  11(A)(III)  hereof,  that such  action  shall  apply  uniformly  to all
outstanding  Rights and (y) may suspend the  exercisability  of the Rights until
the expiration of the Substitution  Period in order to seek any authorization of
additional  shares and/or to decide the  appropriate  form of distribution to be
made pursuant to such second  sentence and to determine the value thereof.  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.  For
purposes of this  SECTION  11(A)(III),  the value of the shares of Common  Stock
shall be the current per share market price (as  determined  pursuant to SECTION
11(D)(I)) on the Section  11(a)(ii) Trigger Date and the per share or fractional
value of any "Common Stock  Equivalent" shall be deemed to equal the current per
share  market price of the Common  Stock.  The Board of Directors of the Company
may, but shall not be required to, establish procedures to allocate the right to
receive  shares of Common Stock upon the exercise of the Rights among holders of
Rights pursuant to this SECTION 11(A)(III).

          (b)  In case the Company  shall fix a record date for the  issuance of
               rights,  options or warrants to all  holders of  Preferred  Stock
               entitling  them (for a period  expiring  within 45 calendar  days
               after such record  date) to subscribe  for or purchase  Preferred
               Stock  (or  shares  having  the  same  rights,   privileges   and
               preferences  as  the  Preferred  Stock   ("equivalent   preferred
               shares"))  or  securities  convertible  into  Preferred  Stock or
               equivalent  preferred  shares at a price  per share of  Preferred
               Stock or  equivalent  preferred  shares (or  having a  conversion
               price  per  share,  if a  security  convertible  into  shares  of
               Preferred  Stock or  equivalent  preferred  shares) less than the
               then  current  per  share  market  price of the  Preferred  Stock
               (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


                                       15

<PAGE>



               such record date by a fraction,  the  numerator of which shall be
               the number of shares of Preferred Stock and equivalent  preferred
               shares  outstanding on such record date plus the number of shares
               of  Preferred  Stock and  equivalent  preferred  shares which the
               aggregate  offering  price  of the  total  number  of  shares  of
               Preferred  Stock  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 market price,  and the  denominator of which shall be the
               number of  shares of  Preferred  Stock and  equivalent  preferred
               shares  outstanding  on such  record  date  plus  the  number  of
               additional shares of Preferred Stock and/or equivalent  preferred
               shares to be offered for  subscription or purchase (or into which
               the  convertible  securities  so  to  be  offered  are  initially
               convertible);  provided,  however,  that in no  event  shall  the
               consideration  to be paid upon the  exercise of one Right be less
               than the  aggregate  par value of the shares of capital  stock of
               the Company  issuable  upon  exercise of one Right.  In case such
               subscription  price may be paid in a consideration part or all of
               which  shall be in a form  other  than  cash,  the  value of such
               consideration  shall be as  determined in good faith by the Board
               of  Directors  of  the  Company,  whose  determination  shall  be
               described in a statement  filed with the Rights Agent.  Shares of
               Preferred Stock and equivalent  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 if
               such rights,  options or warrants are not so issued, the Purchase
               Price shall be adjusted to be the Purchase  Price that would then
               be in effect if such record date had not been fixed.

          (c)  In case the  Company  shall fix a record date for the making of a
               distribution to all holders of the Preferred Stock (including any
               such  distribution  made in connection  with a  consolidation  or
               merger  in which  the  Company  is the  continuing  or  surviving
               corporation) of evidences of indebtedness or assets (other than a
               regular   quarterly  cash  dividend  or  a  dividend  payable  in
               Preferred  Stock) or subscription  rights or warrants  (excluding
               those referred to in SECTION 11(B) hereof), the Purchase Price to
               be in effect  after  such  record  date  shall be  determined  by
               multiplying  the Purchase  Price in effect  immediately  prior to
               such record date by a fraction,  the  numerator of which shall be
               the then current per share market  price of the  Preferred  Stock
               (determined  pursuant  to SECTION  11(D)  hereof) on such  record
               date,  less the fair market value (as determined in good faith by
               the Board of Directors of the Company whose  determination  shall
               be described in a statement  filed with the Rights  Agent) of the
               portion  of the  assets or  evidences  of  indebtedness  so to be
               distributed or of such subscription rights or warrants applicable
               to one share of Preferred  Stock,  and the  denominator  of which
               shall be such current per share market price (determined pursuant
               to  SECTION  11(D)  hereof)  of the  Preferred  Stock;  provided,
               however, that in no event shall the consideration to be paid upon
               the exercise of one Right be less than the aggregate par value of
               the shares of  capital  stock of the  Company  to be issued  upon
               exercise   of  one  Right.   Such   adjustments   shall  be  made
               successively whenever

               such a record date is fixed;  and if such  distribution is not so
               made,  the  Purchase  Price  shall  again be  adjusted  to be the
               Purchase  Price that would then be in effect if such  record date
               had not been fixed.

          (d)  (i) Except as otherwise  provided herein,  for the purpose of any
               computation  hereunder,  the "current per share market  price" of
               any  security  (a  "Security"  for the  purpose  of this  SECTION
               11(D)(I))  on any date  shall be deemed to be the  average of the
               daily  closing  prices  per  share  of such  Security  for the 30
               consecutive  Trading Days (as such term is  hereinafter  defined)
               immediately prior to such date; provided,  however,  that, if the
               current per share  market  price of the  Security  is  determined
               during a period  following the announcement by the issuer of such
               Security  of (A) a  dividend  or  distribution  on such  Security
               payable in shares of such Security or securities convertible into
               such   shares,   or   (B)   any   subdivision,   combination   or
               reclassification of such Security, and prior to the expiration of
               30 Trading Days after the  ex-dividend  date for such dividend or
               distribution or the record date for such subdivision, combination
               or reclassification, then, and in each such case, the current per
               share market price shall be appropriately adjusted to reflect the
               current market price per share  equivalent of such Security.  The
               closing price for each day shall be the last sale price,  regular
               way,  or,  in case no such  sale  takes  place on such  day,  the
               average of the  closing  bid and asked  prices,  regular  way, in
               either case as reported by the principal consolidated transaction
               reporting system with respect to securities listed or admitted to
               trading on the New York Stock Exchange or, if the Security is not
               listed or admitted to trading on the New York Stock Exchange,  as
               reported  in the  principal  consolidated  transaction  reporting
               system  with  respect  to  securities  listed  on  the  principal
               national  securities  exchange on which the Security is listed or
               admitted to trading or, if the Security is not listed or admitted
               to trading on any national securities  exchange,  the last quoted
               price or, if not so quoted,  the  average of the high bid and low
               asked  prices in the  over-the-counter  market,  as  reported  by
               NASDAQ or such other  system then in use, or, if on any such date
               the Security is not quoted by any such organization,  the average
               of  the  closing  bid  and  asked   prices  as   furnished  by  a
               professional  market  maker  making  a  market  in  the  Security
               selected  by the  Board of  Directors  of the  Company.  The term
               "Trading  Day" shall mean a day on which the  principal  national
               securities  exchange on which the  Security is listed or admitted
               to trading is open for the  transaction  of  business  or, if the
               Security  is not listed or  admitted  to trading on any  national
               securities exchange, a Business Day.

               (ii)  For  the  purpose  of  any  computation  hereunder,  if the
               Preferred Stock is publicly traded, the "current per share market
               price" of the  Preferred  Stock shall be determined in accordance
               with the method set forth in SECTION  11(D)(I).  If the Preferred
               Stock is not  publicly  traded but the Common  Stock is  publicly
               traded,  the "current per share  market  price" of the  Preferred
               Stock  shall be  conclusively  deemed to be the current per share
               market  price of the  Common  Stock  as  determined  pursuant  to
               SECTION  11(D)(I)  multiplied by the then  applicable  Adjustment
               Number  (as  defined in and  determined  in  accordance  with the
               Certificate of Designation for the Preferred Stock).

If neither the Common Stock nor the Preferred Stock is publicly traded, "current
per share  market  price" shall mean the fair value per share as  determined  in
good faith by the Board of Directors of the Company,  whose  determination shall
be described in a statement filed with the Rights Agent.

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

          (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 shares of capital  stock of the Company
               other than the Preferred Stock, thereafter the Purchase Price and
               the number of such other shares so receivable  upon exercise of a
               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  Stock  contained  in
               SECTIONS  11(A),  11(B),  11(C),  11(E),  11(H),  11(I) and 11(M)
               hereof,  as applicable,  and the provisions of SECTIONS 7, 9, 10,
               13 and 14 hereof with respect to the Preferred  Stock shall apply
               on like terms, to any such other shares.

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

          (h)  Unless the Company shall have  exercised its election as provided
               in SECTION 11(I), upon each adjustment of the Purchase Price as a
               result of the calculations made in SECTIONS 11(B) and 11(C), each
               Right  outstanding  immediately  prior  to  the  making  of  such
               adjustment  shall thereafter  evidence the right to purchase,  at
               the adjusted Purchase Price,  that number of one  one-thousandths
               of a share of  Preferred  Stock  (calculated  to the  nearest one
               hundred-thousandth of a share of Preferred Stock) obtained by (i)
               multiplying  (x) the  number  of one  one-thousandths  of a share
               purchasable  upon the  exercise of a Right  immediately  prior to
               such  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.



                                       18

          (i)  The Company may elect on or after the date of any  adjustment  of
               the Purchase  Price pursuant to SECTIONS 11(B) or 11(C) hereof to
               adjust the number of Rights,  in substitution  for any adjustment
               in the  number  of one  one-thousandths  of a share of  Preferred
               Stock  purchasable  upon the  exercise  of a  Right.  Each of the
               Rights  outstanding after such adjustment of the number of Rights
               shall be exercisable for the number of one  one-thousandths  of a
               share  of  Preferred  Stock  for  which a Right  was  exercisable
               immediately  prior to such adjustment.  Each Right held of record
               prior to such  adjustment  of the number of Rights  shall  become
               that number of Rights  (calculated to the nearest  one-hundredth)
               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.  Such record date may be the date on which
               the Purchase Price is adjusted or any day thereafter, but, if the
               Right  Certificates  have been issued,  shall be at least 10 days
               later  than  the  date  of  the  public  announcement.  If  Right
               Certificates have been issued, upon each adjustment of the number
               of Rights  pursuant to this  SECTION  11(I),  the Company may, as
               promptly as  practicable,  cause to be  distributed to holders of
               record  of  Right   Certificates   on  such   record  date  Right
               Certificates  evidencing,  subject  to  SECTION  14  hereof,  the
               additional  Rights to which such  holders  shall be entitled as a
               result  of such  adjustment,  or, at the  option of the  Company,
               shall  cause to be  distributed  to such  holders  of  record  in
               substitution and replacement for the Right  Certificates  held by
               such holders prior to the date of adjustment,  and upon surrender
               thereof,  if  required  by the  Company,  new Right  Certificates
               evidencing all the Rights to which such holders shall be entitled
               after such  adjustment.  Right  Certificates so to be distributed
               shall  be  issued,  executed  and  countersigned  in  the  manner
               provided for herein and shall be  registered  in the names of the
               holders  of  record  of Right  Certificates  on the  record  date
               specified in the public announcement.

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

          (k)  Before taking any action that would cause an adjustment  reducing
               the  Purchase  Price  below the then par  value,  if any,  of the
               fraction  of  Preferred  Stock or other  shares of capital  stock
               issuable  upon  exercise of a Right,  the Company  shall take any
               corporate  action  that may, in the  opinion of its  counsel,  be
               necessary in order that the Company may validly and legally issue
               fully paid and  nonassessable  shares of Preferred Stock or other
               such shares 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 issuing to the holder of any Right
               exercised  after such record date the  Preferred  Stock and other
               capital stock or securities of the Company, if any, issuable upon
               such  exercise  over and  above  the  Preferred  Stock  and other
               capital stock or securities of the Company, if any, issuable upon
               such exercise on the basis of the Purchase  Price in effect prior
               to such  adjustment;  provided,  however,  that the Company shall
               deliver  to such  holder  a due  --------  -------  bill or other
               appropriate  instrument evidencing such holder's right to receive
               such additional shares upon the occurrence of the event requiring
               such adjustment.

          (m)  Anything in this SECTION 11 to the contrary notwithstanding,  the
               Company  shall  be  entitled  to  make  such  adjustments  in the
               Purchase  Price,  in  addition  to  those  adjustments  expressly
               required by this  SECTION 11, as and to the extent that it in its
               sole discretion shall determine to be advisable in order that any
               consolidation  or  subdivision of the Preferred  Stock,  issuance
               wholly for cash of any shares of Preferred Stock at less than the
               current market price, issuance wholly for cash of Preferred Stock
               or  securities  which  by their  terms  are  convertible  into or
               exchangeable  for Preferred  Stock,  dividends on Preferred Stock
               payable  in shares of  Preferred  Stock or  issuance  of  rights,
               options or warrants  referred to  hereinabove  in SECTION  11(B),
               hereafter  made by the Company to holders of its Preferred  Stock
               shall not be taxable to such stockholders.

          (n)  Anything in this Agreement to the contrary notwithstanding, if at
               anytime after the date of this Rights  Agreement and prior to the
               Distribution  Date,  the  Company  shall (i)  declare and pay any
               dividend  on the Common  Stock  payable  in Common  Stock or (ii)
               effect a subdivision,  combination or consolidation of the Common
               Stock (by  reclassification  or  otherwise  than by  payment of a
               dividend payable in Common Stock) into a greater or lesser number
               of shares of Common Stock, then, in each such case, the number of
               Rights   associated   with  each  share  of  Common   Stock  then
               outstanding,   or  issued  or  delivered  thereafter,   shall  be
               proportionately  adjusted so that the number of Rights thereafter
               associated  with each share of Common  Stock  following  any such
               event shall equal the result  obtained by multiplying  the number
               of Rights  associated with each share of Common Stock immediately
               prior to each event by a fraction,  the  numerator of which shall
               be the  total  number  of  shares  of  Common  Stock  outstanding
               immediately  prior  to  the  occurrence  of  the  event  and  the
               denominator  of which  shall be the  total  number  of  shares of
               Common Stock outstanding  immediately following the occurrence of
               such event.

          (o)  The Company  agrees that,  after the earlier of the  Distribution
               Date or the  Stock  Acquisition  Date,  it will  not,  except  as
               permitted  by SECTION  23, 24 or 27  hereof,  take (or permit any
               Subsidiary  to take) any  action  if at the time  such  action is
               taken it is

               reasonably   foreseeable   that   such   action   will   diminish
               substantially  or eliminate the benefits  intended to be afforded
               by the Rights.

         SECTION 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES.
Whenever  an  adjustment  is made as  provided  in SECTION 11 or 13 hereof,  the
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  Common  Stock and the
Preferred Stock a copy of such  certificate and (c) mail a brief summary thereof
to each holder of a Right  Certificate in accordance  with SECTION 25 hereof (if
so required under SECTION 25 hereof).  The Rights Agent shall be fully protected
in relying on any such certificate and on any adjustment  therein  contained and
shall not be deemed to have knowledge of any such adjustment unless and until it
shall have received such certificate.

         SECTION 13.  CONSOLIDATION, MERGER  OR SALE  OR TRANSFER  OF  ASSETS OR
EARNING POWER.

          (a)  If,  directly or indirectly,  at any time after the Flip-In Event
               (i) the Company  shall  consolidate  with or shall merge into any
               other  Person,  (ii) any  Person  shall  merge  with and into the
               Company  and the Company  shall be the  continuing  or  surviving
               corporation  of such merger and, in connection  with such merger,
               all or  part  of the  Common  Stock  shall  be  changed  into  or
               exchanged  for stock or other  securities of any other Person (or
               of the  Company)  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 aggregating 50% or more of
               the assets or earning  power of the Company and its  Subsidiaries
               (taken as a whole) to any other Person (other than the Company or
               one or more wholly owned Subsidiaries of the Company),  then upon
               the first  occurrence of such event,  proper  provision  shall be
               made so that:  (A) each holder of a Right (other than Rights that
               have become  void  pursuant to SECTION  11(A)(II)  hereof)  shall
               thereafter have the right to receive,  upon the exercise  thereof
               at the Purchase Price (as theretofore adjusted in accordance with
               SECTION 11(A)(II)  hereof),  in accordance with the terms of this
               Agreement  and in lieu of  shares  of  Preferred  Stock or Common
               Stock of the  Company,  such  number of  validly  authorized  and
               issued,  fully paid, non- assessable and freely  tradeable shares
               of  Common  Stock  of  the  Principal  Party  (as  such  term  is
               hereinafter  defined),  not  subject to any liens,  encumbrances,
               rights of first refusal or other adverse  claims,  as shall equal
               the  result   obtained  by  dividing  the   Purchase   Price  (as
               theretofore adjusted in accordance with SECTION 11(A)(II) hereof)
               by 50% of the current per share  market price of the Common Stock
               of such  Principal  Party  (determined  pursuant to SECTION 11(D)
               hereof)  on the  date  of  consummation  of  such  consolidation,
               merger, sale or transfer;  provided,  however,  that the Purchase
               Price  (as  theretofore   adjusted  in  accordance  with  SECTION
               11(A)(II)  hereof)  and the  number of shares of Common  Stock of
               such Principal Party so receivable upon exercise of a Right shall
               be subject to further  adjustment  as  appropriate  in accordance
               with  SECTION  11(F)  hereof to reflect any events  occurring  in
               respect of the Common


                                       21

<PAGE>



               Stock  of such  Principal  Party  after  the  occurrence  of such
               consolidation, merger, sale or transfer; (B) such Principal Party
               shall  thereafter be liable for, and shall  assume,  by virtue of
               such consolidation, merger, sale or transfer, all the obligations
               and duties of the Company pursuant to this Rights Agreement;  (C)
               the term  "Company"  shall  thereafter be deemed to refer to such
               Principal  Party;  and (D) such  Principal  Party shall take such
               steps  (including,  but not  limited  to,  the  reservation  of a
               sufficient  number of its  shares of Common  Stock in  accordance
               with SECTION 9 hereof) in connection  with such  consummation  of
               any such  transaction  as may be  necessary  to  assure  that the
               provisions  hereof shall  thereafter be applicable,  as nearly as
               reasonably  may be, in relation to the shares of its Common Stock
               thereafter deliverable upon the exercise of the Rights; provided,
               however,   that,   upon   the   subsequent   occurrence   of  any
               consolidation,  merger,  sale or  transfer  of  assets  or  other
               extraordinary  transaction  in respect of such  Principal  Party,
               each  holder of a Right shall  thereupon  be entitled to receive,
               upon  exercise  of a Right and payment of the  Purchase  Price as
               provided  in this  SECTION  13(A),  such  cash,  shares,  rights,
               warrants  and other  property  that such  holder  would have been
               entitled  to  receive  had  such  holder,  at the  time  of  such
               transaction,  owned  the  Common  Stock  of the  Principal  Party
               receivable  upon the exercise of a Right pursuant to this SECTION
               13(A), and such Principal Party shall take such steps (including,
               but not  limited  to,  reservation  of shares of stock) as may be
               necessary  to permit  the  subsequent  exercise  of the Rights in
               accordance with the terms hereof for such cash,  shares,  rights,
               warrants and other property.

          (b)  "Principal Party" shall mean:

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

                  (ii) in the case of any transaction  described in (iii) of the
first sentence in SECTION 13(A) hereof,  the Person that is the party  receiving
the greatest portion of the assets or earning power transferred pursuant to such
transaction  or  transactions,  or,  if each  Person  that  is a  party  to such
transaction or  transactions  receives the same portion of the assets or earning
power so  transferred  or if the Person  receiving  the greatest  portion of the
assets or earning power cannot be  determined,  whichever of such Persons is the
issuer of Common  Stock  having the  greatest  aggregate  market value of shares
outstanding; provided, however, that in any such case described in the foregoing
clause (b)(i) or (b)(ii), if the Common Stock of such Person is not at such time
or has not


                                       22

<PAGE>



been continuously over the preceding 12-month period registered under Section 12
of the Exchange Act, then (1) if such Person is a direct or indirect  Subsidiary
of another Person the Common Stock of which is and has been so  registered,  the
term  "Principal  Party"  shall refer to such other,  or (2) if such Person is a
Subsidiary, directly or indirectly, of more than one Person, the Common Stock of
all of which is and has been so  registered,  the term  "Principal  Party" shall
refer to  whichever  of such  Persons is the issuer of Common  Stock  having the
greatest aggregate market value of shares outstanding,  or (3) if such Person is
owned, directly or indirectly,  by a joint venture formed by two or more Persons
that are not owned,  directly or indirectly,  by the same Person,  the rules set
forth in clauses (1) and (2) above  shall apply to each of the owners  having an
interest  in the  venture  as if the  Person  owned by the joint  venture  was a
Subsidiary of both or all of such joint  venturers,  and the Principal  Party in
each such case shall bear the  obligations  set forth in this  SECTION 13 in the
same ratio as its interest in such Person bears to the total of such interests.

          (c)  The Company shall not consummate any consolidation,  merger, sale
               or transfer  referred to in SECTION  13(A)  hereof  unless  prior
               thereto the  Company and the  Principal  Party  involved  therein
               shall  have  executed  and  delivered  to  the  Rights  Agent  an
               agreement  confirming that the requirements of SECTIONS 13(A) and
               (B) hereof shall  promptly be performed in accordance  with their
               terms and that such  consolidation,  merger,  sale or transfer of
               assets shall not result in a default by the Principal Party under
               this  Agreement  as the  same  shall  have  been  assumed  by the
               Principal  Party  pursuant to  SECTIONS  13(A) and (B) hereof and
               providing  that,  as soon as  practicable  after  executing  such
               agreement pursuant to this SECTION 13, the Principal Party will:

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

                  (ii)  use  its  best  efforts,  if  the  Common  Stock  of the
Principal  Party  shall be listed or  admitted  to trading on the New York Stock
Exchange or on another national securities exchange, to list or admit to trading
(or  continue  the listing of) the Rights and the  securities  purchasable  upon
exercise  of the  Rights  on the New  York  Stock  Exchange  or such  securities
exchange,  or, if the Common Stock of the Principal Party shall not be listed or
admitted  to  trading on the New York Stock  Exchange  or a national  securities
exchange, to cause the Rights and the securities receivable upon exercise of the
Rights to be authorized  for quotation on NASDAQ or on such other system then in
use;

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



                                       23

<PAGE>



                  (iv)  obtain  waivers  of  any  rights  of  first  refusal  or
preemptive  rights in respect of the Common Stock of the Principal Party subject
to purchase upon exercise of outstanding Rights.

          (d)  In  case  the  Principal  Party  has a  provision  in  any of its
               authorized  securities or in its certificate of  incorporation or
               by-laws or other  instrument  governing  its  corporate  affairs,
               which  provision  would  have  the  effect  of (i)  causing  such
               Principal  Party  to  issue  (other  than to  holders  of  Rights
               pursuant  to  this  SECTION  13),  in  connection  with,  or as a
               consequence of, the consummation of a transaction  referred to in
               this  SECTION  13,   shares  of  Common  Stock  or  Common  Stock
               Equivalents of such Principal Party at less than the then current
               market price per share  thereof  (determined  pursuant to SECTION
               11(D) hereof) or securities exercisable for, or convertible into,
               Common Stock or Common Stock  Equivalents of such Principal Party
               at less than such then current  market price,  or (ii)  providing
               for any special payment,  tax or similar  provision in connection
               with the  issuance of the Common  Stock of such  Principal  Party
               pursuant to the  provisions  of SECTION 13, then,  in such event,
               the  Company  hereby  agrees  with each  holder of Rights that it
               shall not  consummate any such  transaction  unless prior thereto
               the Company and such  Principal  Party  shall have  executed  and
               delivered to the Rights Agent a supplemental  agreement providing
               that the provision in question of such Principal Party shall have
               been  canceled,   waived  or  amended,  or  that  the  authorized
               securities  shall be redeemed,  so that the applicable  provision
               will have no effect in connection  with, or as a consequence  of,
               the consummation of the proposed transaction.

          (e)  The Company  covenants  and agrees that it shall not, at any time
               after the Flip-In Event,  enter into any  transaction of the type
               described in clauses (i) through (iii) of SECTION 13(A) hereof if
               (i) at the  time  of or  immediately  after  such  consolidation,
               merger, sale, transfer or other transaction there are any rights,
               warrants  or  other  instruments  or  securities  outstanding  or
               agreements  in  effect  that  would  substantially   diminish  or
               otherwise  eliminate the benefits  intended to be afforded by the
               Rights,  (ii) prior to,  simultaneously with or immediately after
               such consolidation,  merger, sale, transfer or other transaction,
               the  stockholders  of  the  Person  who  constitutes,   or  would
               constitute,  the  Principal  Party for purposes of SECTION  13(B)
               hereof shall have received a  distribution  of Rights  previously
               owned by such Person or any of its  Affiliates  or  Associates or
               (iii) the form or nature of  organization  of the Principal Party
               would preclude or limit the exercisability of the Rights.

         SECTION 14.  FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

          (a)  The Company shall not be required to issue fractions of Rights or
               to distribute Right Certificates that evidence  fractional Rights
               (except prior to the Distribution Date in accordance with SECTION
               11(N) hereof). In lieu of such fractional Rights,  there shall be
               paid to the  registered  holders of the Right  Certificates  with
               regard  to  which  such  fractional  Rights  would  otherwise  be
               issuable, an amount in cash equal to the same


                                       24

<PAGE>



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

          (b)  The Company shall not be required to issue fractions of Preferred
               Stock (other than  fractions  that are integral  multiples of one
               one-thousandth  of a share of Preferred  Stock) or to  distribute
               certificates  that evidence  fractional shares of Preferred Stock
               (other  than  fractions  that  are  integral   multiples  of  one
               one-thousandth  of a share of Preferred  Stock) upon the exercise
               or exchange of Rights.  Interests in fractions of Preferred Stock
               in  integral  multiples  of  one  one-thousandth  of a  share  of
               Preferred  Stock 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,
               however,  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 Stock  represented by such depositary  receipts.
               In lieu of  fractional  shares of  Preferred  Stock  that are not
               integral  multiples of one one-thousandth of a share of Preferred
               Stock,  the Company shall pay to the registered  holders of Right
               Certificates  at the time such Rights are  exercised or exchanged
               as herein  provided an amount in cash equal to the same  fraction
               of the current  market value of a whole share of Preferred  Stock
               (as  determined in accordance  with SECTION 14(A) hereof) for the
               Trading  Day  immediately  prior to the date of such  exercise or
               exchange.

          (c)  The Company shall not be required to issue fractions of shares of
               Common  Stock  or  to  distribute   certificates   that  evidence
               fractional  shares of Common  Stock upon the exercise or exchange
               of Rights. In lieu of such fractional shares of Common Stock,


                                       25

<PAGE>



               the  Company  shall  pay to the  registered  holder  of the Right
               Certificates  with  regard  to which  such  fractional  shares of
               Common Stock would  otherwise be issuable an amount in cash equal
               to the same fraction of the current market value of a whole share
               of Common Stock (as  determined in accordance  with SECTION 14(A)
               hereof) for the Trading Day immediately prior to the date of such
               exercise or exchange.

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

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

         SECTION 16.  AGREEMENT OF RIGHT  HOLDERS.  Every holder of a Right,  by
accepting  the same,  consents  and agrees with the Company and the Rights Agent
and with every other holder of a Right that:

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

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

          (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 Common Stock certificate) is registered as the absolute
               owner   thereof   and   of   the   Rights    evidenced    thereby
               (notwithstanding  any  notations  of  ownership or writing on the
               Right Certificates or the Common Stock certificate made by anyone
               other than the Company or the Rights

               Agent) for all purposes  whatsoever,  and neither the Company nor
               the Rights Agent shall be affected by any notice to the contrary.

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

         SECTION 18.  CONCERNING THE RIGHTS AGENT.

          (a)  The  Company  agrees  to  pay  to  the  Rights  Agent  reasonable
               compensation for all services  rendered by it hereunder and, from
               time to time,  on  demand of the  Rights  Agent,  its  reasonable
               expenses and counsel fees and other disbursements incurred in the
               administration  and execution of this  Agreement and the exercise
               and performance of its duties hereunder.  The Company also agrees
               to  indemnify  the  Rights  Agent  for,  and to hold it  harmless
               against, any loss,  liability or expense,  incurred without gross
               negligence,  bad faith or willful  misconduct  on the part of the
               Rights Agent, for anything done or omitted by the Rights Agent in
               connection  with  the  acceptance  and   administration  of  this
               Agreement,  including the costs and expenses of defending against
               any claim of liability arising therefrom, directly or indirectly.
               In no case will the Rights Agent be liable for special, indirect,
               incidental or consequential loss or damage of any kind whatsoever
               (including but not limited to lost  profits),  even if the Rights
               Agent has been advised of the possibility of such damages.

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

         SECTION 19.  MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS AGENT.

          (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 stock  transfer or
               corporate  trust  powers  of the  Rights  Agent or any  successor
               Rights  Agent,  shall be the  successor to the Rights Agent under
               this  Agreement  without the  execution or filing of any paper or
               any  further  act on the  part  of  any  of the  parties  hereto;
               provided,  however,  that such corporation  would be eligible for
               appointment  as a successor  Rights Agent under the provisions of
               SECTION  21  hereof.  In case at the time such  successor  Rights
               Agent shall succeed to the agency created by this Agreement,  any
               of the 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 opinion of such counsel shall
               be full and complete  authorization  and protection to the Rights
               Agent as to any  action  taken or omitted by it in good faith and
               in accordance with such opinion.

          (b)  Whenever in the  performance  of its duties under this  Agreement
               the Rights Agent shall deem it  necessary  or desirable  that any
               fact or matter be proved or  established  by the Company prior to
               taking or  suffering  any action  hereunder,  such fact or matter
               (unless other evidence in respect thereof be herein  specifically
               prescribed)  may  be  deemed  to  be   conclusively   proved  and
               established by a certificate signed by the


                                       28

<PAGE>



               President  and the  Secretary of the Company and delivered to the
               Rights Agent; and such certificate shall be full authorization to
               the Rights  Agent for any action  taken or suffered in good faith
               by it under the  provisions  of this  Agreement in reliance  upon
               such certificate.

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

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

          (e)  The Rights Agent shall not be under any responsibility in respect
               of the validity of this  Agreement or the  execution and delivery
               hereof  (except the due execution  hereof by the Rights Agent) or
               in respect of the validity or execution of any Right  Certificate
               (except   its   countersignature   thereof);   nor  shall  it  be
               responsible  for any  breach by the  Company of any  covenant  or
               condition   contained   in  this   Agreement   or  in  any  Right
               Certificate;  nor shall it be  responsible  for any change in the
               exercisability  of the Rights (including the Rights becoming void
               pursuant to SECTION  11(A)(II)  hereof) or any  adjustment in the
               terms of the Rights  provided  for in  SECTIONS 3, 11, 13, 23 and
               24, or the  ascertaining  of the  existence  of facts  that would
               require any such change or adjustment (except with respect to the
               exercise of Rights evidenced by Right  Certificates after receipt
               of a  certificate  furnished  pursuant to SECTION 12,  describing
               such change or adjustment);  nor shall it by any act hereunder be
               deemed  to  make  any   representation  or  warranty  as  to  the
               authorization  or reservation of any shares of Preferred Stock or
               other  securities to be issued  pursuant to this Agreement or any
               Right  Certificate or as to whether any shares of Preferred 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 person reasonably believed by the Rights Agent
               to be one of the President or the  Secretary of the Company,  and
               to  apply  to  such  officers  for  advice  or   instructions  in
               connection  with its  duties,  and it shall not be liable for any
               action taken or suffered by it in good faith in  accordance  with
               instructions of any such officer or for any delay in acting while
               waiting for those  instructions.  Any  application  by the Rights
               Agent for written instructions from the


                                       29

<PAGE>



               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 and/or  after which
               such action shall be taken or such  omission  shall be effective.
               The Rights  Agent shall not be liable for any action taken by, or
               omission  of,  the  Rights  Agent in  accordance  with a proposal
               included in any such  application  on or after 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  application  unless any such  officer  shall have
               consented in writing to an earlier date) unless,  prior to taking
               any  such  action  (or  the  effective  date  in the  case  of an
               omission),   the  Rights  Agent  shall  have   received   written
               instructions  in  response  to such  application  specifying  the
               action to be taken or omitted.

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

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

          (j)  If, with  respect to any Rights  Certificate  surrendered  to the
               Rights Agent for exercise or transfer,  the certificate contained
               in the form of assignment or the form of election to purchase set
               forth on the  reverse  thereof,  as the case may be, has not been
               completed to certify the holder is not an Acquiring Person (or an
               Affiliate or Associate thereof),  the Rights Agent shall not take
               any further  action with  respect to such  requested  exercise or
               transfer without first consulting with the Company.

         SECTION 21. CHANGE OF RIGHTS  AGENT.  The Rights Agent or any successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer agent
of the Common Stock or Preferred  Stock by  registered or certified  mail,  and,
following the  Distribution  Date, 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 days'  notice in  writing,  mailed to the Rights  Agent or
successor  Rights Agent,  as the case may be, and to each transfer  agent of the
Common Stock or Preferred Stock by registered or certified mail, and,  following
the  Distribution  Date, to the holder 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


                                       30

<PAGE>



shall appoint a successor to the Rights Agent. If the Company shall fail to make
such appointment  within a period of 30 days after giving notice of such removal
or after it has been  notified in writing of such  resignation  or incapacity by
the  resigning  or  incapacitated  Rights  Agent  or by the  holder  of a  Right
Certificate  (who shall,  with such  notice,  submit his Right  Certificate  for
inspection by the Company),  then the 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 either (A) a corporation  organized  and doing  business
under  the laws of the  United  States  or the laws of any  state of the  United
States or the District of Columbia,  in good  standing,  having an office in the
State of Texas or the State of New York,  which is authorized under such laws to
exercise  corporate trust or stock transfer powers and is subject to supervision
or  examination  by federal or state  authority and which has at the time of its
appointment  as Rights  Agent a  combined  capital  and  surplus of at least $50
million,  or (B) an  affiliate  of  such  corporation.  After  appointment,  the
successor Rights Agent shall be vested with the same powers,  rights, duties and
responsibilities  as if it had been  originally  named as Rights  Agent  without
further act or deed; but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent any property at the time held by it hereunder, and
execute and deliver any further assurance, conveyance, act or deed necessary for
the  purpose.  Not later than the  effective  date of any such  appointment  the
Company shall file notice thereof in writing with the  predecessor  Rights Agent
and each transfer agent of the Common Stock or Preferred Stock,  and,  following
the  Distribution  Date,  mail a notice  thereof in  writing  to the  registered
holders of the Right  Certificates.  Failure to give any notice  provided for in
this SECTION 21, however,  or any defect therein,  shall not affect the legality
or validity of the resignation or removal of the 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 forms
as may be approved by its Board of Directors to reflect any adjustment or change
in the  Purchase  Price  and the  number  or kind or  class of  shares  or other
securities  or  property  purchasable  under  the  Right  Certificates  made  in
accordance  with the provisions of this  Agreement.  In addition,  in connection
with the issuance or sale of Common Stock  following the  Distribution  Date and
prior to the  Expiration  Date, the Company may with respect to shares of Common
Stock so issued or sold  pursuant  to (i) the  exercise of stock  options,  (ii)
under any employee plan or arrangement,  (iii) upon the exercise,  conversion or
exchange  of  securities,  notes or  debentures  issued by the Company or (iv) a
contractual  obligation  of the  Company,  in each  case  existing  prior to the
Distribution Date, issue Right Certificates  representing the appropriate number
of Rights in connection with such issuance or sale.

         SECTION 23.  REDEMPTION.

          (a)  The Board of  Directors  of the Company may, at any time prior to
               the Flip-In  Event,  redeem all but not less than all of the then
               outstanding  Rights  at a  redemption  price of $.01  per  Right,
               appropriately adjusted to reflect any stock split, stock dividend
               or  similar  transaction  occurring  after the date  hereof  (the
               redemption price being


                                       31

<PAGE>



               hereinafter   referred  to  as  the  "Redemption   Price").   The
               redemption  of the Rights may be made  effective at such time, on
               such basis and with such  conditions as the Board of Directors in
               its sole discretion may establish.  The Redemption Price shall be
               payable,  at the option of the Company, in cash, shares of Common
               Stock,  or such  other  form of  consideration  as the  Board  of
               Directors shall determine.

          (b)  Immediately  upon the action of the Board of  Directors  ordering
               the  redemption  of the Rights  pursuant to paragraph (a) of this
               SECTION 23 (or at such later time as the Board of  Directors  may
               establish for the effectiveness of such redemption),  and without
               any further action and without any notice,  the right to exercise
               the Rights will  terminate  and the only right  thereafter of the
               holders of Rights shall be to receive the Redemption  Price.  The
               Company shall promptly give public notice of any such redemption;
               provided,  however,  that the failure to give,  or any defect in,
               any such notice shall not affect the validity of such redemption.
               Within  10 days  after  such  action  of the  Board of  Directors
               ordering the  redemption of the Rights (or such later time as the
               Board of Directors may establish  for the  effectiveness  of such
               redemption), the Company shall mail a notice of redemption to all
               the  holders  of  the  then  outstanding  Rights  at  their  last
               addresses  as they appear upon the  registry  books of the Rights
               Agent or, prior to the  Distribution  Date, on the registry books
               of the transfer  agent for the Common Stock.  Any notice which is
               mailed in the  manner  herein  provided  shall be  deemed  given,
               whether or not the holder  receives the notice.  Each such notice
               of redemption  shall state the method by which the payment of the
               Redemption Price will be made.

         SECTION 24.  EXCHANGE.

          (a)  The Board of Directors of the Company may, at its option,  at any
               time after the Flip- In Event,  exchange  all or part of the then
               outstanding  and  exercisable  Rights  (which  shall not  include
               Rights  that have  become  void  pursuant  to the  provisions  of
               SECTION  11(A)(II)  hereof) for Common Stock at an exchange ratio
               of one share of Common Stock per Right, appropriately adjusted to
               reflect any stock split,  stock  dividend or similar  transaction
               occurring  after the date  hereof  (such  amount per Right  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 an Acquiring  Person shall
               have  become  the  Beneficial  Owner of shares  of  Common  Stock
               aggregating  50% or more  of the  shares  of  Common  Stock  then
               outstanding.  From and after the occurrence of an event specified
               in SECTION 13(A)  hereof,  any Rights that  theretofore  have not
               been exchanged pursuant to this SECTION 24(A) shall thereafter be
               exercisable  only in  accordance  with  SECTION 13 and may not be
               exchanged  pursuant to this  SECTION  24(A).  The exchange of the
               Rights by the Board of  Directors  may be made  effective at such
               time,  on such  basis  and with such  conditions  as the Board of
               Directors in its sole discretion may establish.

          (b)  Immediately upon the  effectiveness of the action of the Board of
               Directors  of the  Company  ordering  the  exchange of any Rights
               pursuant  to  paragraph  (a) of this  SECTION 24 and  without any
               further action and without any notice, the right to exercise such
               Rights shall terminate and the only right  thereafter of a holder
               of such  Rights  shall be to  receive  that  number  of shares of
               Common  Stock  equal to the  number of such  Rights  held by such
               holder  multiplied  by the  Exchange  Ratio.  The  Company  shall
               promptly  give  public  notice  of any such  exchange;  provided,
               however,  that the failure to give, or any defect in, such notice
               shall not affect the validity of such exchange. The Company shall
               promptly mail a notice of any such exchange to all of the holders
               of the Rights so exchanged at their last addresses as they appear
               upon the registry  books of the Rights Agent.  Any notice that is
               mailed in the  manner  herein  provided  shall be  deemed  given,
               whether or not the holder  receives the notice.  Each such notice
               of  exchange  will state the method by which the  exchange of the
               shares of Common Stock for Rights will be effected  and, upon any
               partial  exchange,  the number of Rights that will be  exchanged.
               Any  partial  exchange  shall be  effected  pro rata based on the
               number  of Rights  (other  than  Rights  that  have  become  void
               pursuant to the provisions of SECTION  11(A)(II)  hereof) held by
               each holder of Rights.

          (c)  The Company may at its option substitute, and, if there shall not
               be sufficient  shares of Common Stock issued but not  outstanding
               or  authorized  but  unissued to permit an exchange of Rights for
               Common Stock as  contemplated in accordance with this SECTION 24,
               the Company shall substitute to the extent of such insufficiency,
               for each share of Common  Stock that would  otherwise be issuable
               upon exchange of a Right,  a number of shares of Preferred  Stock
               or fraction thereof (or equivalent preferred shares, as such term
               is defined  in SECTION  11(B))  such that the  current  per share
               market price (determined pursuant to SECTION 11(D) hereof) of one
               share  of  Preferred  Stock  (or  equivalent   preferred   share)
               multiplied by such number or fraction is equal to the current per
               share  market  price of one  share of  Common  Stock  (determined
               pursuant  to  SECTION  11(D)  hereof)  as of  the  date  of  such
               exchange.

         SECTION 25.  NOTICE OF CERTAIN EVENTS.

          (a)  In case the  Company  shall at any time after the  earlier of the
               Distribution  Date or the Stock  Acquisition  Date propose (i) to
               pay any dividend  payable in stock of any class to the holders of
               its  Preferred  Stock or to make any  other  distribution  to the
               holders of its  Preferred  Stock (other than a regular  quarterly
               cash  dividend),  (ii) to offer to the  holders of its  Preferred
               Stock  rights or warrants  to  subscribe  for or to purchase  any
               additional  shares of  Preferred  Stock or shares of stock of any
               class or any other securities, rights or options, (iii) to effect
               any  reclassification  of  its  Preferred  Stock  (other  than  a
               reclassification involving only the subdivision or combination of
               outstanding  Preferred  Stock),  (iv) to effect the  liquidation,
               dissolution  or  winding  up of the  Company,  or (v) to pay  any
               dividend on the Common Stock payable in Common Stock or to effect
               a subdivision, combination or consolidation of the

               Common Stock (by reclassification or otherwise than by payment of
               dividends in Common Stock),  then, in each such case, the Company
               shall give to each holder of a Right  Certificate,  in accordance
               with SECTION 26 hereof, a notice of such proposed  action,  which
               shall  specify  the record  date for the  purposes  of such stock
               dividend,  or distribution of rights or warrants,  or the date on
               which  such  liquidation,  dissolution  or  winding up is to take
               place and the date of participation therein by the holders of the
               Common Stock and/or  Preferred  Stock,  if any such date is to be
               fixed,  and  such  notice  shall  be so  given in the case of any
               action covered by clause (i) or (ii) above at least 10 days prior
               to the record date for determining holders of the Preferred Stock
               for  purposes of such  action,  and in the case of any such other
               action,  at least 10 days prior to the date of the taking of such
               proposed  action  or the  date of  participation  therein  by the
               holders of the Common Stock  and/or  Preferred  Stock,  whichever
               shall be the earlier.

          (b)  In case any event  described  in SECTION  11(A)(II) or SECTION 13
               shall  occur  then  the  Company  shall  as soon  as  practicable
               thereafter  give to each  holder  of a Right  Certificate  (or if
               occurring  prior to the  Distribution  Date,  the  holders of the
               Common Stock) in accordance  with SECTION 26 hereof,  a notice of
               the  occurrence of such event,  which notice shall  describe such
               event and the  consequences  of such  event to  holders of Rights
               under SECTION 11(A)(II) and SECTION 13 hereof.

         SECTION 26. NOTICES. Notices or demands authorized by this Agreement to
be given or made by the Rights  Agent or by the holder of any Right  Certificate
to or on the Company shall be sufficiently  given or made if sent by first-class

         SECTION  27.  SUPPLEMENTS  AND  AMENDMENTS.  Except as  provided in the
penultimate  sentence  of this  SECTION  27,  for so long as the Rights are then
redeemable,  the Company may in its sole and absolute discretion, and the Rights

Agreement in any respect  without the approval of any holders of the Rights.  At
any time when the Rights are no longer  redeemable,  except as  provided  in the
penultimate  sentence of this  SECTION 27, the Company may, and the Rights Agent
shall, if the Company so directs, supplement or amend this Agreement without the
approval  of any  holders  of  Rights in order to (i) cure any  ambiguity,  (ii)

again to become  redeemable  or cause the  Agreement  again to become  amendable
other  than in  accordance  with this  sentence;  further,  provided,  that this
Agreement  may not be  supplemented  or amended to lengthen,  pursuant to clause

time period unless such lengthening is for the purpose of protecting,  enhancing
or  clarifying  the rights of,  and/or the  benefits  to, the holders of Rights.
Notwithstanding  anything  contained  in  this  Agreement  to the  contrary,  no
supplement or amendment shall be made which changes the Redemption  Price.  Upon
the delivery of a Certificate  from an  appropriate  officer of the Company that

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 Stock) any legal or equitable right, remedy or claim under this
Agreement; but this Agreement shall be for the sole and exclusive benefit of the

(and, prior to the Distribution Date, the Common Stock).

administration of this Agreement (including, without limitation, a determination
to  redeem  or not  redeem  the  Rights or to amend  this  Agreement).  All such
actions,  calculations,   interpretations  and  determinations  (including,  for
purposes of clause (y) below,  all omissions with respect to the foregoing) that
are done or made by the Board of Directors  of the Company in good faith,  shall
(x) be final,  conclusive  and binding on the  Company,  the Rights  Agent,  the
holders of the Rights,  as such, and all other parties,  and (y) not subject the

full force and effect and shall in no way be affected, impaired or invalidated.

         SECTION 32.  GOVERNING LAW. This  Agreement and each Right  Certificate

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.

                                       OF
                        DALLAS SEMICONDUCTOR CORPORATION
                         Pursuant to Section 151 of the
                        Delaware General Corporation Law


         DALLAS SEMICONDUCTOR  CORPORATION, a corporation organized and existing
under the laws of the State of Delaware,  in accordance  with the  provisions of
Section 103 thereof, DOES HEREBY CERTIFY:

         That  pursuant to the  authority  vested in the Board of  Directors  in
accordance with the provisions of the Certificate of  Incorporation  of the said
Corporation,  as amended,  the said Board of Directors on May 20, 1999,  adopted
the  following  resolution  creating  a series  of  shares  of  Preferred  Stock
designated as "Series A Junior Participating Preferred Stock":

                  RESOLVED,  that pursuant to the authority  vested in the Board
         of Directors of this  Corporation in accordance  with the provisions of
         the  Certificate of  Incorporation,  a series of Preferred  Stock,  par
         value $.10 per share, of the Corporation be and hereby is created,  and
         that the  designation  and number of shares  thereof and the voting and
         other  powers,  preferences  and relative,  participating,  optional or
         other  rights of the  shares  of such  series  and the  qualifications,

                  SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

         1.  Designation and Amount.  There shall be a series of Preferred Stock
that shall be designated as "Series A Junior Participating Preferred Stock," and
the number of shares  constituting  such series shall be 50,000.  Such number of
shares may be increased or decreased by  resolution  of the Board of  Directors;
provided,  however, that no decrease shall reduce the number of shares of Series
A Junior  Participating  Preferred  Stock to less than the number of shares then
issued and  outstanding  plus the number of shares  issuable  upon  exercise  of
outstanding  rights,  options or  warrants  or upon  conversion  of  outstanding
securities issued by the Corporation.

         2.       Dividends and Distributions.

                  (A) Subject to the prior and superior  right of the holders of
any shares of any class or series of stock of the Corporation  ranking prior and
superior  to the shares of Series A Junior  Participating  Preferred  Stock with
respect to  dividends,  the  holders of shares of Series A Junior  Participating
Preferred Stock,  shall be entitled to receive,  when, as and if declared by the
Board of Directors  out of funds legally  available  for the purpose,  quarterly
dividends  payable in cash on the 15th day of January,  April, July and October,
in each year (each such date being  referred to herein as a "Quarterly  Dividend
Payment Date"),  commencing on the first Quarterly  Dividend  Payment Date after
the  first  issuance,  of a share  or  fraction  of a share  of  Series A Junior
Participating  Preferred  Stock,  in an amount per share (rounded to the nearest
cent) equal to the Adjustment  Number (as defined below) times the aggregate per
share  amount  of all  cash  dividends,  and the  Adjustment  Number  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,  par value  $.02 per share,  of the
Corporation  (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
Junior Participating Preferred Stock. The "Adjustment Number" shall initially be
1000. If the Corporation shall at any time after September 10, 1999 (the "Rights
Declaration  Date"), (i) declare and pay any dividend on Common Stock payable in
shares of Common Stock,  (ii)  subdivide the  outstanding  Common Stock or (iii)
combine the  outstanding  Common Stock into a smaller number of shares,  then in
each such case the Adjustment  Number in effect  immediately prior to such event
shall be adjusted  by  multiplying  such  Adjustment  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) The  Corporation  shall declare a dividend or distribution
on the Series A Junior  Participating  Preferred  Stock as provided in paragraph
(A) above immediately after it declares a dividend or distribution on the Common
Stock (other than a dividend payable in shares of Common Stock).

                  (C) The  Board  of  Directors  may fix a  record  date for the
determination  of holders of shares of Series A Junior  Participating  Preferred
Stock  entitled  to  receive  payment  of a dividend  or  distribution  declared
thereon, which record date shall be no more than 60 days prior to the date fixed
for the payment thereof.

                  (B)  Except  as  required  by law and by  SECTION  10  hereof,
holders of Series A Junior  Participating  Preferred Stock shall have no special

are  entitled  to vote with  holders of Common  Stock as set forth  herein)  for
taking any corporate action.

         4.       Certain Restrictions.

                  (A)  Whenever  quarterly   dividends  or  other  dividends  or
distributions  payable on the Series A Junior  Participating  Preferred Stock as
provided  in SECTION 2 are in  arrears,  thereafter  and until all  accrued  and
unpaid dividends and distributions, whether or not declared, on shares of Series

the Corporation shall not:

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

                           (ii)     declare or  pay dividends  on  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
Junior  Participating  Preferred  Stock,  except  dividends  paid ratably on the
Series A Junior Participating Preferred Stock and all such parity stock on which
dividends  are payable or in arrears in proportion to the total amounts to which
the holders of all such shares are then entitled; or

                           (iii)    purchase or otherwise acquire for considera-
tion any shares of Series A Junior Participating  Preferred Stock, or any shares
of stock  ranking on a parity with the Series A Junior  Participating  Preferred
Stock,  except  in  accordance  with a  purchase  offer  made in  writing  or by
publication (as determined by the Board of Directors) to all holders of Series A
Junior Participating Preferred Stock, or to such holders and holders of any such
shares ranking on a parity therewith, 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 4,  purchase or  otherwise  acquire such shares at such time and in
such manner.

         5.  Reacquired  Shares.  Any  shares of  Series A Junior  Participating

whatsoever  shall be retired  promptly after the acquisition  thereof.  All such
shares shall upon their retirement become authorized

but  unissued  shares of  Preferred  Stock and may be  reissued as part of a new
series of Preferred  Stock to be created by  resolution  or  resolutions  of the
Board of Directors,  subject to any conditions and  restrictions on issuance set
forth herein.

         6.  Liquidation,  Dissolution or Winding Up. (A) Upon any  liquidation,
dissolution  or  winding  up of the  Corporation,  voluntary  or  otherwise,  no
distribution  shall be made to the  holders  of shares of stock  ranking  junior
(either as to dividends or upon  liquidation,  dissolution or winding up) to the
Series A Junior Participating Preferred Stock unless, prior thereto, the holders
of shares of Series A Junior  Participating  Preferred Stock shall have received
an amount per share (the "Series A Liquidation Preference") equal to the greater
of (i)  $1.00  plus  an  amount  equal  to  accrued  and  unpaid  dividends  and
distributions  thereon whether or not declared,  to the date of such payment, or
(ii) the  Adjustment  Number  times the per  share  amount of all cash and other
property to be distributed in respect of the Common Stock upon such liquidation,
dissolution or winding up of the Corporation.

                  (B) If, however,  there are not sufficient assets available to
permit  payment  in  full  of  the  Series  A  Liquidation  Preference  and  the
liquidation  preferences  of all  other  classes  and  series  of  stock  of the
Corporation,   if  any,  that  rank  on  a  parity  with  the  Series  A  Junior
Participating  Preferred Stock in respect thereof, then the assets available for
such  distribution  shall be distributed  ratably to the holders of the Series A
Junior  Participating  Preferred  Stock and the holders of such parity shares in
proportion to their respective liquidation preferences.

                  (C) Neither  the merger or  consolidation  of the  Corporation
into or with another  corporation nor the merger or  consolidation  of any other
corporation  into or with the  Corporation  shall be deemed to be a liquidation,
dissolution or winding up of the Corporation  within the meaning of this SECTION
6.

         7. Consolidation, Merger, Etc. In case the Corporation shall enter into
any  consolidation,  merger,  combination  or other  transaction  in  which  the
outstanding shares of Common Stock are exchanged for or changed into other stock
or securities,  cash and/or any other property, then in any such case each share
of  Series A Junior  Participating  Preferred  Stock  shall at the same  time be
similarly  exchanged  or changed in an amount per share equal to the  Adjustment
Number 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.

         8. No  Redemption.  Shares of Series A Junior  Participating  Preferred
Stock shall not be subject to redemption by the Company.

         9. Ranking.  The Series A Junior  Participating  Preferred  Stock shall
rank  junior to all other  series of the  Preferred  Stock as to the  payment of
dividends, and as to the distribution of assets upon liquidation, dissolution or
winding up,  unless the terms of any such series shall  provide  otherwise,  and
shall rank senior to the Common Stock as to such matters.

         10.  Amendment.  At any  time  that  any  shares  of  Series  A  Junior
Participating Preferred Stock are outstanding,  the Certificate of Incorporation
of the  Corporation  shall not be amended in any  manner  that would  materially
alter or change the powers, preferences or special rights of the Series A Junior
Participating  Preferred  Stock  so as to  affect  them  adversely  without  the
affirmative  vote of the  holders of  two-thirds  of the  outstanding  shares of
Series A Junior Participating Preferred Stock, voting separately as a class.

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

         IN WITNESS WHEREOF,  the undersigned has executed this Certificate this
10th day of September, 1999.

Rights Agreement  reference is hereby made for a full description of the rights,
limitations  of rights,  obligations,  duties and  immunities  hereunder  of the
Rights Agent, the Company and the holders of the Right  Certificates.  Copies of

Stock  or of any  other  securities  of the  Company  which  may at any  time be
issuable on the exercise or exchange hereof, nor shall anything contained in the
Rights  Agreement or herein be construed  to confer upon the holder  hereof,  as
such, any of the rights of a stockholder of the Company or any right to vote for
the election of directors or upon any matter  submitted to  stockholders  at any
meeting thereof,  or to give or withhold consent to any corporate  action, or to

                          SHARES OF PREFERRED STOCK OF
                        DALLAS SEMICONDUCTOR CORPORATION

         The  Board  of  Directors  of  DALLAS  SEMICONDUCTOR  CORPORATION  (the
"Company")  has declared a dividend of one  preferred  share  purchase  right (a
"Right") for each  outstanding  share of common stock, par value $.02 per share,
of the Company (the "Common  Stock").  The dividend is payable on September  21,
1999 (the "Record Date"), to the stockholders of record on that date. Each Right
entitles the registered  holder to purchase from the Company one  one-thousandth
of a share of Series A Junior Participating  Preferred Stock, par value $.10 per
share,  of the  Company  (the  "Preferred  Stock")  at a price  of $250  per one
one-thousandth of a share of Preferred Stock (the "Purchase Price"),  subject to
adjustment.  The  description  and terms of the Rights are set forth in a Rights
Agreement  dated as of September  10, 1999, as the same may be amended from time
to  time  (the  "Rights   Agreement"),   between  the  Company  and  CHASEMELLON
SHAREHOLDER SERVICES, L.L.C., as Rights Agent (the "Rights Agent").

certain exceptions,  an "Acquiring Person") has acquired beneficial ownership of
15% or more of the  outstanding  shares of Common Stock or (ii) 10 business days
(or such later  date as may be  determined  by action of the Board of  Directors
prior to such  time as any  person or group of  affiliated  persons  becomes  an
Acquiring Person) following the 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  shares of Common  Stock (the earlier of such dates being called the
"Distribution  Date"), the Rights will be evidenced,  with respect to any of the
Common Stock  certificates  outstanding  as of the Record  Date,  by such Common
Stock certificate together with a copy of this Summary of Rights.

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

surrender  for  transfer  of  any   certificates  for  shares  of  Common  Stock
outstanding as of the Record Date,  even without such notation or a copy of this
Summary of Rights,  will also  constitute the transfer of the Rights  associated
with the shares of Common Stock  represented  by such  certificates.  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  Stock as of the  close of  business  on the  Distribution  Date and such
separate Right Certificates alone will evidence the Rights.

         The Rights are not exercisable until the Distribution  Date. The Rights
will expire on September 9, 2009 (the "Final Expiration Date"), unless the Final
Expiration  Date is  advanced  or  extended  or unless the  Rights  are  earlier
redeemed or exchanged by the Company, in each case as described below.

         The Purchase Price payable, and the number of shares of Preferred Stock
or other  securities  or  property  issuable,  upon  exercise  of the Rights are
subject to  adjustment  from time to time to prevent  dilution  (i) upon a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Stock,  (ii) upon the grant to holders of the Preferred  Stock of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Stock at a  price,  or
securities  convertible into Preferred Stock with a conversion  price, less than
the  then-current  market  price  of the  Preferred  Stock  or  (iii)  upon  the
distribution  to holders of the Preferred  Stock of evidences of indebtedness or
assets  (excluding  regular  periodic  cash  dividends or  dividends  payable in
Preferred  Stock)  or of  subscription  rights or  warrants  (other  than  those
referred to above).

         The number of  outstanding  Rights is subject  to  adjustment  upon the
occurrence  of a stock  dividend on the Common Stock payable in shares of Common
Stock or  subdivisions,  consolidations  or  combinations  of the  Common  Stock
occurring, in any such case, prior to the Distribution Date.

         Shares of Preferred Stock  purchasable upon exercise of the Rights will
not be redeemable.  Each share of Preferred Stock will be entitled, when, as and
if declared,  to a dividend payment per share equal to an aggregate  dividend of
1,000 times the dividend  declared per share of Common Stock.  Upon liquidation,
dissolution  or winding up of the Company,  the holders of the  Preferred  Stock
will be entitled to a minimum  preferential payment of $1.00 per share (plus any
accrued but unpaid  dividends)  but will be entitled to an aggregate  payment of
1,000 times the payment made per share of Common Stock.  Each share of Preferred
Stock will have 1,000 votes,  voting  together with the Common  Stock.  Finally,
upon any merger,  consolidation or other transaction in which outstanding shares
of Common Stock are converted or exchanged,  each share of Preferred  Stock will
be  entitled  to receive  1,000  times the amount  received  per share of Common
Stock. These rights are protected by customary antidilution provisions.

         Because of the nature of the Preferred  Stock's  dividend,  liquidation
and voting rights,  the value of the one  one-thousandth  interest in a share of
Preferred Stock purchasable upon exercise of each Right should  approximately be
the value of one share of Common Stock.

         If any person or group of affiliated or associated  persons  becomes an
Acquiring Person,  each holder of a Right, other than Rights  beneficially owned
by the Acquiring Person (which will thereupon become void), will thereafter have
the right to receive upon exercise of a Right that number of shares of Preferred
Stock having a market value of two times the exercise price of the Right.

         If, after a person or group has become an Acquiring Person, 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, proper provisions will be
made so that each holder of a Right (other than Rights  beneficially owned by an
Acquiring  Person which will have become void) will thereafter have the right to
receive  upon the  exercise of a Right that number of shares of common  stock of
the person with whom the Company has engaged in the  foregoing  transaction  (or
its  parent)  that at the time of such  transaction  have a market  value of two
times the exercise price of the Right.

         At any time after any person or group  becomes an Acquiring  Person and
prior to the earlier of one of the events  described in the previous  paragraphs
or the  acquisition by such Acquiring  Person of 50% or more of the  outstanding
shares of Common  Stock,  the Board of Directors of the Company may exchange the
Rights (other than Rights owned by such Acquiring  Person which will have become
void),  in whole or in part, for shares of Common Stock or Preferred Stock (or a
series of the Company's  preferred stock having equivalent  rights,  preferences
and  privileges),  at an  exchange  ratio of one  share of  Common  Stock,  or a
fractional  share of Preferred  Stock (or other preferred  stock)  equivalent in
value thereto, per Right.

         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  shares of Preferred  Stock or Common Stock
will be issued  (other  than  fractions  of  Preferred  Stock that are  integral
multiples of one one-thousandth of a share of Preferred Stock, 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 current  market price of
the Preferred Stock or the Common Stock.

         At any time prior to the time an Acquiring  Person  becomes  such,  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 and 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.

         For so long as the Rights are then redeemable,  the Company may, except
with respect to the redemption price,  amend the Rights Agreement in any manner.
After the Rights are no longer redeemable,  the Company may, except with respect
to the redemption price,  amend the Rights Agreement in any manner that does not
adversely affect the interests of holders of the Rights.

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