<PAGE>
ITEM 1. DESCRIPTION OF REGISTRANT'S SECURITIES TO BE REGISTERED.

     The  response  to Item 1 is  hereby  amended  to read  in its  entirety  as
follows:

     Effective August 9, 1999,  Burr-Brown  Corporation (the "Company")  amended
and  restated  the  Company's   stockholder  rights  plan  (the  "Rights  Plan")
originally  adopted  in 1989,  which was due to expire on August 9,  1999.  Each
Right  entitles  the  registered   holder  to  purchase  from  the  Company  one
one-thousandth  (1/1000) of a share of Series A Junior  Participating  Preferred
Stock, $.01 par value (the "Series A Preferred Stock"), of the Company.

     The  Rights  have  certain  anti-takeover  effects.  The  Rights  may cause
substantial  dilution to a person or group that  attempts to acquire the Company
on terms not approved by the Board of Directors. The Rights should not interfere
with any merger or other business  combination  approved by the Board because of
the Board of Directors' ability to redeem the Rights, as discussed below.

     The  description  and terms of the Rights are set forth in the  Amended and
Restated  Rights  Agreement (the "Amended and Restated  Agreement")  between the
Company and Harris  Trust and Savings  Bank,  as Rights  Agent.  The summary set
forth below does not purport to be complete  and is qualified in its entirety by
the Amended and Restated  Agreement  filed herewith and  incorporated  herein by
reference.

NEW AMENDMENTS

     The primary effects of the amendments to the Rights Plan are:

     *  To  provide  that  each  Right  entitles  the  holder  to  purchase  one
one-thousandth  (1/1000) of a share of Series A Preferred Stock, rather than one
one-hundredth  (1/100) of a share of the Company's common stock,  $.01 par value
(the "Common Stock");

     * To increase the purchase  price upon  exercise of a Right (the  "Purchase
Price")  from $47.50 per share of Common  Stock to $220.00 per share (each share
now  being  equivalent  to one  one-thousandth  (1/1000)  of a share of Series A
Preferred Stock);

     * To extend the term of the Rights and the Rights  Plan from August 9, 1999
until August 9, 2009;

     * To  decrease  the stock  ownership  trigger of the Rights from 20% to 15%
(excluding  persons who  inadvertently  cross the 15%  threshold  and  excluding
current  stockholders who exceed the 15% threshold on the date of adoption,  who
may  then   increase   share   ownership  by  an  additional  5%  under  certain
circumstances without triggering the Rights).

                                        2
<PAGE>
RIGHTS ATTACHED TO COMMON STOCK INITIALLY

     Common Stock certificates  currently evidence the Rights. A notation on the
certificates  incorporates the Rights Plan and advises the certificate holder of
the existence of the Rights.  Until  triggered,  the Rights are transferred only
with the Common  Stock  certificates.  Common  Stock  certificates  issued after
August 9, 1999 will contain a legend  referencing the existence of a stockholder
rights plan. The surrender for transfer of outstanding Common Stock certificates
will also  constitute  the  transfer  of the Rights  associated  with the Common
Stock.

DISTRIBUTION OF RIGHTS

     The  Company  will mail  separate  certificates  evidencing  the  Rights to
holders  of  record  of  the  Common  Stock  on  the  "Distribution  Date."  The
Distribution  Date will be the date the Rights  separate  from the Common Stock,
and will be the earlier to occur of the following two events:

     * the close of  business on the first day  following a public  announcement
that a person  or group of  affiliated  or  associated  persons  (an  "Acquiring
Person") has  acquired  beneficial  ownership of 15% or more of the  outstanding
Common Stock; or

     * 10 business days following the  commencement  of, or  announcement  of an
intention to make, a tender or exchange  offer the  consummation  of which would
result in the  beneficial  ownership by a person or group of 15% or more of such
outstanding Common Stock.

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 August 9,
2009, unless earlier redeemed or extended by the Board.

RIGHT TO PURCHASE COMPANY STOCK

     In the event a person  becomes the owner of 15% or more of the  outstanding
shares of Common Stock and thus becomes an Acquiring Person (a "Flip-In Event"),
the Rights not held by the Acquiring Person "flip-in" and, instead of continuing
as rights to buy Series A Preferred Stock, become rights to buy from the Company
shares of Common Stock  having a value equal to two times the Purchase  Price of
the Right. In other words, a Rights holder (other than the Acquiring Person) may
purchase Common Stock at a 50% discount.

     In the event there is insufficient  Common Stock to permit exercise in full
of the Rights,  the Company must issue shares of Series A Preferred Stock, cash,
property or other  securities  of the Company with an  aggregate  value equal to
twice the Purchase Price.

                                        3
<PAGE>
     Upon the occurrence of the any such Flip-In  Event,  any Rights owned by an
Acquiring Person, its affiliates and associates and certain transferees thereof,
shall become null and void.

RIGHT TO PURCHASE ACQUIRING PERSON STOCK

     In the event that a person becomes an Acquiring Person, the Company is then
merged, and the Common Stock is exchanged or converted in the merger,  then each
Right (other than those  formerly  held by the  Acquiring  Person,  which became
void)  would  "flip-over"  and be  exercisable  for a number of shares of common
stock of the acquiring  company  having a market value of two times the exercise
price of the Right.  In other words,  a Rights holder may purchase the acquiring
company's common stock at a 50% discount.

EXCHANGE OF RIGHTS FOR COMMON STOCK

     After a Flip-In Event but before a "flip-over"  event (as described  above)
occurs and before an  Acquiring  Person  becomes the owner of 50% or more of the
Common Stock,  the Board may cause the Rights (either in whole or in part) to be
exchanged  for  shares of  Common  Stock (or  fractional  interests  in Series A
Preferred  Stock,  or  equivalent  securities,  of equal  value) at a one-to-one
exchange ratio or pursuant to an equivalent  cashless  exercise  method.  Rights
held by the Acquiring Person; however, which became void upon the Flip-In Event,
would not be entitled to participate in such exchange.

REDEMPTION

     The Rights may be redeemed by the Board at a  redemption  price of $.01 per
Right at any time prior to the earlier of:

     * the time that a person or a group becomes an Acquiring Person, or

     *  August  9,  2009,  the  expiration  date  of the  Amended  and  Restated
Agreement.

Immediately  upon  redemption and without further action and without any notice,
the right to  exercise  the  Rights  will  terminate  and the only  right of the
holders will be to receive the redemption price.

EXPIRATION OF RIGHTS

     The Rights will  expire on August 9, 2009,  unless the  expiration  date is
extended by amendment or unless the Rights are earlier  redeemed or exchanged by
the Company as described above.

                                        4
<PAGE>
AMENDMENTS OR SUPPLEMENTS

     For so long as the  Rights are  redeemable,  the terms of the Rights may be
amended or  supplemented  by the Board of Directors at any time and from time to
time  without the  consent of the  holders of the  Rights.  At any time when the
Rights are not  redeemable,  the Board of Directors may amend or supplement  the
terms of the Rights,  provided that such amendment does not adversely affect the
interests of the holders of the Rights.

NO RIGHTS AS STOCKHOLDERS

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

MISCELLANEOUS

     In order to prevent  dilution,  the Purchase Price, the number of shares of
Series A  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 the Amended and Restated Agreement.

     The Company is not required to issue  fractions of Rights or to  distribute
Right Certificates  which evidence  fractional Rights (except as may be provided
for in the Amended and Restated  Agreement).  In lieu of such fractional Rights,
the Company will pay to the registered  holders of the Right  Certificates  with
regard to which such fractional Rights would otherwise be issuable, an amount of
cash equal to the same fraction of the current market value of a whole Right.

                      AMENDED AND RESTATED RIGHTS AGREEMENT

     AMENDED AND RESTATED RIGHTS AGREEMENT ("Agreement"),  dated as of August 9,
1999, between Burr-Brown  Corporation,  a Delaware  corporation (the "Company"),
and Harris Trust and Savings Bank, an Illinois banking  corporation (the "Rights
Agent").

     WHEREAS,  the Board of Directors of the Company  authorized  and declared a
dividend  of one right  (each,  a "Right")  for each  share of Common  Stock (as
hereinafter  defined) of the Company outstanding as of the Close of Business (as
hereinafter  defined)  on  August  10,  1989 (the  "Record  Date"),  each  Right
initially  representing  the right to purchase  one-one  hundredth of a share of
Common  Stock  (subject  to  adjustment),  upon the  terms  and  subject  to the
conditions set forth in the Rights  Agreement  dated as of July 21, 1989 between
the  Company  and  Valley   National  Bank  of  Arizona,   N.A.  (the  "Original
Agreement"),  and further authorized and directed the issuance of one Right with
respect to each share of Common Stock that shall become outstanding  between the
Record Date and the earliest of the  Distribution  Date, the Redemption  Date or
the Final Expiration Date (as such terms are hereinafter defined).

     WHEREAS,  on July 23, 1999, the Board of Directors of the Company  approved
and authorized the amendment and  restatement of the Original  Agreement and the
appointment  of the Rights  Agent,  and the Rights Agent  desires to accept said
appointment;

     WHEREAS,  the Company  desires  and  directs the Rights  Agent to amend and
restate the terms and conditions of the Original Agreement in their entirety, as
set forth herein.

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

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

     "Acquiring  Person"  shall  mean any  Person  (as such term is  hereinafter
defined) who or which,  together with all  Affiliates  and  Associates  (as such
terms are hereinafter defined) of such Person, shall be the Beneficial Owner (as
such term is  hereinafter  defined) of 15% or more of the shares of Common Stock
of the  Company  then  outstanding,  but  shall not  include  the  Company,  any
Subsidiary  (as such term is hereinafter  defined) of the Company,  any employee
benefit  plan of the Company or any  Subsidiary  of the  Company,  or any entity
holding  shares of Common  Stock for or  pursuant to the terms of any such plan.
Notwithstanding the foregoing:

          (i) no  Person or Group  (as such  term is  herein  defined)  shall be
     deemed to be an "Acquiring  Person" because as of the  "Commencement  Date"
     such Person or Group  beneficially owns 15% or more of the Common Shares of
     the Company then outstanding; PROVIDED, HOWEVER, that if any such Person or
     Group shall, after the Commencement Date, become the Beneficial Owner of an
     additional  5% or more of the  Common  Shares of the  Company  (other  than
     pursuant to a dividend or  distribution  paid or made by the Company on the
     outstanding  Common  Stock or  pursuant  to a split or  subdivision  of the
<PAGE>
     outstanding  Common  Stock,  and excluding any Common Stock over which such
     Person obtains  beneficial  ownership,  after the  Commencement  Date, as a
     result of any transfer from any other member of the same Group),  then such
     Person or Group shall be deemed to be an "Acquiring  Person." If any Person
     or Group transfers beneficial ownership of any Common Shares of the Company
     held by such Person or Group to another Person or Persons  which,  in turn,
     (i)  are  beneficially  owned  entirely  by  such  transferor  or,  if  the
     transferor is a Group, are beneficially owned by Persons who are members of
     such Group,  or (ii)  beneficially  own all of such  transferor  or, if the
     transferor is a Group,  beneficially  own all of one or more of the Persons
     who are members of such Group,  the transferee  shall,  for purposes of the
     definition of "Acquiring Person" in this Agreement,  be deemed to have held
     all such transferred shares of Common Shares since the date the shares were
     originally  acquired by the  transferor.  All shares of Common Stock of the
     Company beneficially owned by a Person who is a member of a Group or by the
     estate or any  beneficiaries of the estate of a Person who is a member of a
     Group shall be deemed to be shares beneficially owned by such Group.

          (ii) 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
     beneficially  owned by such  Person to 15% or more of the  shares of Common
     Stock of the Company then outstanding;  PROVIDED, HOWEVER, that if a Person
     shall  become the  Beneficial  Owner of 15% or more of the shares of Common
     Stock of the Company then outstanding,  by reason of share purchases by the
     Company and shall,  after such share  purchases by the Company,  become the
     Beneficial  Owner of any  additional  shares of Common Stock of the Company
     (other  than  pursuant to a dividend  or  distribution  paid or made by the
     Company  on  the  outstanding  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" hereunder; and

          (iii) if the Board of  Directors  of the  Company  determines  in good
     faith that a Person who would  otherwise be an  "Acquiring  Person"  became
     such inadvertently (including,  without limitation, because (A) such Person
     was unaware that it  beneficially  owned a percentage  of Common Stock that
     would otherwise  cause such Person to be an "Acquiring  Person" or (B) such
     Person was aware of the extent of its Beneficial  Ownership of Common Stock
     but  had  no  actual  knowledge  of the  consequences  of  such  Beneficial
     Ownership  under this  Agreement)  and without any intention of changing or
     influencing control of the Company, then such Person shall not be deemed to
     be or to  have  become  an  "Acquiring  Person"  for any  purposes  of this
     Agreement  unless and until such Person shall have failed to divest itself,
     as soon as  practicable  (as  determined,  in good  faith,  by the Board of
     Directors of the Company),  of Beneficial  Ownership of a sufficient number
     of shares of Common  Stock so that such  Person  would no longer  otherwise
     qualify as an "Acquiring Person."

                                        2
<PAGE>
     "Adjustment Shares" has the meaning set forth in SECTION 11(a)(ii).

     "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 such term is hereinafter defined).

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

          (i) which such Person or any of such Person's Affiliates or Associates
     beneficially owns, directly or indirectly, for purposes of SECTION 13(d) of
     the Exchange Act and Rule 13d-3  thereunder (or any comparable or successor
     law or regulation); or

          (ii)  which  such  Person  or  any  of  such  Person's  Affiliates  or
     Associates,  directly or indirectly,  has (A) the right to acquire (whether
     such right is  exercisable  immediately  or only after the passage of time)
     pursuant to any agreement,  arrangement or understanding (whether or not in
     writing,  other than customary agreements with and between underwriters and

Stock registered in the names of the holders thereof (which  certificates  shall
also  be  deemed  to  be  Rights   Certificates)  and  not  by  separate  Rights
Certificates,  and  (y)  the  right  to  receive  Rights  Certificates  will  be

will countersign,  and the Company will send or cause to be sent (and the Rights
Agent  will,  if  requested  and  at  the  expense  of  the  Company,  send)  by

Common  Stock as of the  Close of  Business  on the  Distribution  Date,  at the
address  of  such  holder  shown  on  the  records  of  the  Company,  a  Rights
Certificate,   in  substantially  the  form  of  Exhibit  B  hereto  (a  "Rights
Certificate"),  evidencing  one Right for each share of Common Stock so held. As
of the  Distribution  Date,  the Rights will be evidenced  solely by such Rights
Certificates.

     (b) On the Record Date, or as soon as practicable  thereafter,  the Company
sent a copy of a summary of rights to purchase  Common  Stock,  which summary of
rights has been  amended to  reflect  the  amended  and  restated  terms of this
Agreement (such summary of rights,  as amended hereby,  is  substantially in the
form  of  Exhibit  C  hereto)  (the  "Summary  of  Rights"),   by   first-class,
postage-prepaid  mail, to each record holder of shares of Common Stock as of the
Close of Business on the Record Date, at the address of such holder shown on the
records of the Company.  With respect to certificates for shares of Common Stock
outstanding as of the Record Date, until the Distribution  Date, the Rights will
be evidenced by such certificates registered in the names of the holders thereof
together with a copy of the Summary of Rights.  Until the Distribution  Date (or
if earlier,  the Expiration Date), the surrender for transfer of any certificate
for shares of Common Stock  outstanding  on the Record  Date,  with or without a
copy of the  Summary  of Rights  attached  thereto,  shall also  constitute  the
transfer of the Rights  associated  with the shares of Common Stock  represented
thereby.

     (c)  Certificates  for  shares of Common  Stock  which  become  outstanding
(including, without limitation, reacquired shares of Common Stock referred to in
the last sentence of this  paragraph (c)) 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 as set forth in a Rights Agreement (as amended)  between  Burr-Brown
     Corporation and Harris Trust and Savings Bank, as Rights Agent, dated as of
     August 9,  1999 (the  "Rights  Agreement"),  the terms of which are  hereby
     incorporated  herein  by  reference  and a copy of  which is on file

                                        7
<PAGE>
     at the principal executive offices of Burr-Brown Corporation. 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.  Burr-Brown  Corporation  will  mail  to the  holder  of  this
     certificate a copy of the Rights Agreement  without charge after receipt of
     a written request therefor.  Under certain  circumstances,  as set forth in
     the Rights Agreement,  Rights issued to any Person who becomes an Acquiring
     Person (as defined in the Rights  Agreement),  whether currently held by or
     on behalf of such person or by any subsequent  holder,  may become null and
     void.

With respect to such  certificates  containing the foregoing  legend,  until the
earlier of the Distribution  Date and the Expiration Date, the Rights associated
with the  shares of  Common  Stock  represented  by such  certificates  shall be
evidenced by such certificates alone, and the surrender for transfer of any such
certificate shall also constitute the transfer of the Rights associated with the
shares of Common  Stock  represented  thereby.  In the  event  that the  Company
purchases or acquires any shares of Common Stock after the Record Date but prior
to the Distribution Date, any Rights associated with such shares of Common Stock
shall be deemed  cancelled and retired so that the Company shall not be entitled
to exercise any Rights  associated  with the shares of Common Stock which 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 RIGHTS CERTIFICATES.

     (a) The Rights  Certificates  (and the forms of election to purchase shares
and of assignment to be printed on the reverse  thereof) shall be  substantially
the same as  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 transaction  reporting system on which the Rights may from
time to time be listed,  or to conform to usage.  Subject to the  provisions  of
SECTION 11 and  SECTION 22 hereof,  the Rights  Certificates  shall  entitle the
holders  thereof  to  purchase  such  number of  one-one  thousandth  of a share
("Units") of Preferred Stock as shall be set forth therein at the price per Unit
of Preferred Stock set forth therein,  but the number of such Units of Preferred
Stock and the Purchase Price shall be subject to adjustment as provided herein.

     (b) Any Rights  Certificate  issued pursuant hereto that represents  Rights
beneficially  owned by: (i) an Acquiring Person or any Associate or Affiliate of
an Acquiring  Person,  (ii) a transferee of an Acquiring  Person (or of any such
Associate or  Affiliate)  who becomes a transferee  after the  Acquiring  Person
becomes  such or  (iii) a  transferee  of an  Acquiring  Person  (or of any such
Associate or Affiliate) who becomes a transferee  prior to or concurrently  with
the

                                        8
<PAGE>
Acquiring Person becoming such and receives such Rights pursuant to either (A) a
transfer (whether or not for consideration) from the Acquiring Person to holders
of equity  interests  in such  Acquiring  Person or to any Person with whom such
Acquiring  Person has any continuing  agreement,  arrangement  or  understanding
regarding the transferred  Rights or (B) a transfer which the Board of Directors
of the Company has determined is part of a plan,  arrangement  or  understanding
which has as a primary purpose or effect  avoidance of SECTION 7(e) hereof shall
contain (to the extent feasible) the following legend:

     The Rights  represented by this Rights Certificate are or were beneficially
     owned by a Person who was or became an Acquiring  Person or an Affiliate or
     Associate of an  Acquiring  Person (as such terms are defined in the Rights
     Agreement, as amended,  between Burr-Brown Corporation and Harris Trust and
     Savings  Bank,  as Rights  Agent,  dated as of August 9, 1999 (the  "Rights
     Agreement").   Accordingly,   this  Rights   Certificate   and  the  Rights
     represented hereby may become null and void in the circumstances  specified
     in SECTION 7(e) of the Rights Agreement.

     Notwithstanding  this  paragraph  4(b),  the omission of a legend shall not
affect the enforceability of any part of this Agreement.

     SECTION 5. COUNTERSIGNATURE AND REGISTRATION.

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

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

     SECTION  6.  TRANSFER,   SPLIT-UP,   COMBINATION  AND  EXCHANGE  OF  RIGHTS
CERTIFICATES; MUTILATED, DESTROYED, LOST OR STOLEN RIGHTS CERTIFICATES.

Certificates  may be  transferred,  split up,  combined or exchanged for another
Rights  Certificate or Rights  Certificates,  entitling the registered holder to
purchase a like number of Units of Preferred  Stock (or,  following a Triggering
Event, other securities, cash or other assets, as the case may be) as the Rights
Certificate  or Rights  Certificates  surrendered  then  entitled such holder to
purchase.  Any  registered  holder  desiring to transfer,  split up,  combine or
exchange any Rights  Certificate or Rights  Certificates shall make such request
in  writing  delivered  to the  Rights  Agent,  and shall  surrender  the Rights
Certificate or Rights  Certificates  to be  transferred,  split up,  combined or
exchanged at the office of the Rights Agent designated for such purpose. Neither
the  Rights  Agent  nor the  Company  shall  be  obligated  to take  any  action
whatsoever  with  respect  to  the  transfer  of  any  such  surrendered  Rights
Certificate  until the  registered  holder shall have  completed  and signed the
certificate  contained  in the form of  assignment  on the reverse  side of such
Rights  Certificate  and shall have  provided  such  additional  evidence of the
identity of the Beneficial Owner (or former  Beneficial  Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent  shall,  subject to SECTIONs  4(b),  7(e) and 14 hereof,  countersign  and
deliver  to  the  person  entitled  thereto  a  Rights   Certificate  or  Rights
Certificates,  as the case may be, as so  requested.  The  Company  may  require
payment of a sum sufficient to cover any tax or governmental  charge that may be
imposed in connection  with any transfer,  split up,  combination or exchange of
Rights Certificates.

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

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

     (d) In case the registered holder of any Rights  Certificate shall exercise
less than all the Rights evidenced thereby, a new Rights Certificate  evidencing
a number of Rights  equivalent  to the  number of Rights  remaining  unexercised
shall be issued by the  Rights  Agent to the

                                       11

registered holder of such Rights Certificate or to such registered holder's duly
authorized assigns, subject to the provisions of SECTION 14 hereof.

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

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

     SECTION 8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES.

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

                                       12
<PAGE>
to the Company,  or shall, at the written  request of the Company,  destroy such
cancelled Rights  Certificates,  and in such case shall deliver a certificate of
destruction thereof to the Company.

     SECTION 9. RESERVATION AND AVAILABILITY OF PREFERRED STOCK.

     (a) The Company  covenants  and agrees that it will use its best efforts to
cause  to be  reserved  and  kept  available  out of and  to the  extent  of its
authorized  and unissued  shares of  Preferred  Stock or any shares of Preferred
Stock held in its  treasury,  not  reserved  for another  purpose,  that will be
sufficient to permit the exercise in full of all  outstanding  Rights.  Upon the
occurrence  of any events  resulting in an increase in the  aggregate  number of
shares of Preferred Stock (or other equity  securities of the Company)  issuable
upon  exercise of all  outstanding  Rights above the number then  reserved,  the
Company shall make appropriate increases in the number of shares so reserved.

     (b) If the Units of  Preferred  Stock to be issued and  delivered  upon the
exercise of the Rights are at any time listed on a national  securities exchange
or included for quotation on any transaction reporting system, the Company shall
during the period from the Distribution Date to the Expiration Date use its best
efforts  to cause all shares  reserved  for such  issuance  to be listed on such
exchange or included for quotation on any such transaction reporting system upon
official notice of issuance upon such exercise.

     (c) The  Company  shall  use  its  best  efforts  to (i)  file,  as soon as
practicable  following the earliest date after the first occurrence of a SECTION
11(a)(ii) Event in which the  consideration  to be delivered by the Company upon
exercise of the Rights has been determined in accordance with SECTION 11(a)(iii)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a registration  statement under the Securities Act, with respect to
the securities  purchasable upon exercise of the Rights on an appropriate  form,
(ii)  cause  such  registration   statement  to  become  effective  as  soon  as
practicable  after such filing and (iii) cause such  registration  statement  to
remain effective (with a prospectus at all times meeting the requirements of the
Securities  Act) until the earlier of (A) the date as of which the Rights are no
longer  exercisable for such securities and (B) the Expiration Date. The Company
will also take such action as may be appropriate  under, or to ensure compliance
with, the securities or "blue sky" laws of the various states in connection with
the  exercisability  of  the  Rights.  Notwithstanding  any  provision  of  this
Agreement  to  the  contrary,  the  Rights  shall  not  be  exercisable  in  any
jurisdiction, unless the requisite qualification in such jurisdiction shall have
been  obtained,  or an  exemption  therefrom  shall  be  available  and  until a
registration statement has been declared effective.

     (d) The Company  covenants  and agrees that it will take all such action as
may be necessary to ensure that all Units of Preferred Stock (and, following the
occurrence of a Triggering  Event,  any other  securities  that may be delivered
upon exercise of Rights) shall, at the time of delivery of the  certificates for
such Units of  Preferred  Stock or other  securities  (subject to payment of the
Purchase  Price),  be duly and validly  authorized and issued and fully paid and
non-assessable.

                                       13
<PAGE>
     (e) The Company further  covenants and agrees that it will pay when due and
payable any and all federal and state  transfer  taxes and charges  which may be
payable in respect of the issuance or delivery of the Rights  Certificates or of
any Units of Preferred Stock upon the exercise of Rights. The Company shall not,
however,  be required to pay any transfer tax which may be payable in respect of
any transfer or delivery of Rights  Certificates  to a person other than, or the
issuance  or  delivery  of  certificates  or  depositary  receipts  for Units of
Preferred  Stock in a name  other  than that of,  the  registered  holder of the
Rights Certificate  evidencing Rights surrendered for exercise or to issue or to
deliver any  certificates  or depositary  receipts for Units of Preferred  Stock
upon the  exercise  of any  Rights  until any such tax shall have been paid (any
such tax being payable by the holder of such Rights  Certificate  at the time of
surrender)  or  until  it  has  been  established  to the  Company's  reasonable
satisfaction that no such tax is due.

     SECTION 10. PREFERRED STOCK RECORD DATE.

     Each Person in whose name any certificate for Units of Preferred Stock (or,
following the occurrence of a Triggering Event, other securities) is issued upon
the  exercise  of Rights  shall for all  purposes  be deemed to have  become the
holder of record of the Units of Preferred  Stock (or,  following the occurrence
of a  Triggering  Event,  other  securities)  represented  thereby  on, and such
certificate  shall  be  dated,  the  date  upon  which  the  Rights  Certificate
evidencing  such Rights was duly  surrendered  and payment of the 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 (or,
following the occurrence of a Triggering Event, other securities) 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;  PROVIDED  FURTHER,  HOWEVER,  that if  delivery  of Units of
Preferred  Stock is delayed  pursuant to SECTION  9(c),  such  Persons  shall be
deemed to have become the record  holders of such Units of Preferred  Stock only
when such  Units of  Preferred  Stock  first  become  deliverable.  Prior to the
exercise of the Rights  evidenced  thereby,  the holder of a Rights  Certificate
shall not be entitled to any rights of a stockholder of the Company with respect
to  securities  for which the Rights shall be  exercisable,  including,  without
limitation, the right to vote, to receive dividends or other distributions or to
exercise any preemptive  rights, and shall not be entitled to receive any notice
of any  proceedings  of the  Company,  except as provided  herein.  Prior to the
exercise of the Rights  evidenced  thereby,  the holder of a Rights  Certificate
shall not be entitled to any rights of a holder of a Unit of Preferred Stock for
which the Rights shall be exercisable,  including, without limitation, the right
to  vote,  to  receive  dividends  or other  distributions  or to  exercise  any
preemptive  rights,  and shall not be  entitled  to  receive  any  notice of any
proceedings of the Company, except as provided herein.

     SECTION 11.  ADJUSTMENT  OF PURCHASE  PRICE,  NUMBER AND KIND OF SHARES AND
NUMBER OF RIGHTS.

     The  Purchase  Price,  the number and kinds of  securities  covered by each
Right and the number of Rights  outstanding  are subject to adjustment from time
to time as provided in this SECTION 11.

          (a) (i) In the event the  Company  shall at any time after the date of
     this  Agreement  (A) declare a dividend on the  Preferred  Stock payable in
     shares  of  Preferred  Stock,  (B)  subdivide  the  outstanding  shares  of
     Preferred Stock, (C) combine the outstanding Preferred Stock into a smaller
     number of shares  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 Rights  exercised  after such time shall
     be entitled to receive the  aggregate  number and kind of shares of capital
     stock which,  if such Rights had been exercised  immediately  prior to such
     date and at a time when the Preferred  Stock  transfer books of the Company
     were  open,  such  holder  would have  owned  upon such  exercise  and been
     entitled to receive by virtue of such dividend, subdivision, combination or
     reclassification;   PROVIDED,   HOWEVER,   that  in  no  event   shall  the
     consideration  to be paid upon the  exercise  of one Right be less than the
     aggregate par value of the shares of capital stock of the Company  issuable
     upon  exercise of one Right.  If an event  occurs  which  would  require an
     adjustment  under both this  SECTION  11(a)(i) and SECTION  11(a)(ii),  the
     adjustment  provided for in this SECTION  11(a)(i) shall be in addition to,
     and shall be made prior to, any  adjustment  required  pursuant  to SECTION
     11(a)(ii).

               (ii) Subject to SECTION 24 of this  Agreement,  in the event that
          (A)  any  Acquiring  Person  or  any  Associate  or  Affiliate  of any
          Acquiring  Person,  at any  time  after  the  date of this  Agreement,
          directly or indirectly,  shall (1) merge into the Company or otherwise
          combine with the Company and the Company  shall be the  continuing  or
          surviving  corporation  of such  merger or  combination  and shares of
          Company Common Stock shall remain  outstanding  and unchanged,  (2) in
          one  transaction or a series of  transactions,  transfer any assets to
          the Company or any of its  Subsidiaries  in  exchange  (in whole or in
          part) for shares of Company Common Stock, for other equity  securities
          of the Company or any such Subsidiary,  or for securities  exercisable
          for or convertible into shares of equity  securities of the Company or
          any of its  Subsidiaries  (whether  shares of Company  Common Stock or
          otherwise)  or  otherwise  obtain  from  the  Company  or  any  of its
          Subsidiaries, with or without consideration,  any additional shares of
          such equity  securities or securities  exercisable  for or convertible
          into  such  equity  securities  other  than  pursuant  to a  pro  rata
          distribution  to all holders of shares of Company  Common  Stock,

                                       15
<PAGE>
          (3) sell, purchase,  lease, exchange,  mortgage,  pledge,  transfer or
          otherwise  acquire or dispose  of, in one  transaction  or a series of
          transactions,  to, from or with the Company or any of its Subsidiaries
          or any employee  benefit plan  maintained by the Company or any of its
          Subsidiaries  or any trustee or  fiduciary  with  respect to such plan
          acting in such capacity,  assets  (including  securities) on terms and
          conditions  less  favorable to the Company or such  Subsidiary or plan
          than those that could have been obtained in arm's-length  negotiations
          with an unaffiliated third party, other than pursuant to a transaction
          set  forth  in  SECTION  13(a)  hereof,  (4)  sell,  purchase,  lease,
          exchange,  mortgage,  pledge, transfer or otherwise acquire or dispose
          of, in one transaction or a series of  transactions,  to, from or with
          the Company or any of its  Subsidiaries  or any employee  benefit plan
          maintained by the Company or any of its Subsidiaries or any trustee or
          fiduciary  with  respect to such plan acting in such  capacity  (other
          than transactions, if any, consistent with those engaged in, as of the
          date  hereof,  by the  Company  and  such  Acquiring  Person  or  such
          Associate or Affiliate),  assets  (including  securities or intangible
          assets)  having an aggregate  fair market value of more than $250,000,
          other  than  pursuant  to a  transaction  set forth in  SECTION  13(a)
          hereof, (5) receive, or any designee,  agent or representative of such
          Acquiring  Person or any  Affiliate  or  Associate  of such  Acquiring
          Person shall receive,  any compensation from the Company or any of its
          Subsidiaries  other than  compensation  for full-time  employment as a
          regular  employee at rates in  accordance  with the  Company's (or its
          Subsidiaries') past practices, or (6) receive the benefit, directly or
          indirectly  (except  proportionately  as a holder of shares of Company
          Common Stock or as required by law or governmental regulation), of any
          loans, advances,  guarantees, pledges or other financial assistance or
          any tax credits or other tax advantages provided by the Company or any
          of its  Subsidiaries  or any employee  benefit plan  maintained by the
          Company or any of its  Subsidiaries  or any trustee or fiduciary  with
          respect to such plan acting in such capacity;  or (B) any Person shall
          become an  Acquiring  Person,  unless the event  causing the Person to
          become an  Acquiring  Person  is a  transaction  set forth in  SECTION
          13(a); or (C) during such time as there is an Acquiring Person,  there
          shall be any  reclassification  of securities  (including  any reverse
          stock split),  or  recapitalization  of the Company,  or any merger or
          consolidation of the Company with any of its Subsidiaries or any other
          transaction or series of transactions  involving the Company or any of
          its  Subsidiaries,  other than a transaction or  transactions to which
          the  provisions of SECTION 13(a) apply (whether or not with or into or
          otherwise  involving  an  Acquiring  Person),  which  has the  effect,
          directly  or   indirectly,   of   increasing   by  more  than  1%  the
          proportionate  share of the outstanding  shares of any class of equity
          securities of the Company or any of its Subsidiaries  that is directly
          or indirectly beneficially owned by any Acquiring Person or any Person
          or any Associate or Affiliate of any Acquiring Person;

then  promptly  following  the  occurrence  of an  event  described  in  SECTION
11(a)(ii)(A),  (B) or (C) (a "SECTION 11(a)(ii) Event"),  proper provision shall
be made so that (I) the  Purchase  Price shall be  adjusted  to be the  Purchase
Price in effect  immediately  prior to the SECTION 11(a)(ii) Event multiplied by
the  number  of Units of  Preferred  Stock  for  which a Right  was  exercisable

                                       16
<PAGE>
immediately prior to such SECTION 11(a)(ii) Event, whether or not such Right was
then  exercisable,  and (II)  each  holder of a Right,  (except  as set forth in
paragraph 7(e) above), 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 this  Agreement  and in lieu of Units 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 price
(determined  pursuant to SECTION 11(d) hereof) for shares of Common Stock on the
date of such Triggering Event,  subject to further adjustment as provided herein
(such  number of shares of Common  Stock  being  hereinafter  referred to as the
"Adjustment Shares").

               (iii) In the event  that the  number  of  shares of Common  Stock
          which are authorized by the Company's Certificate of Incorporation but
          not  outstanding or reserved for issuance for purposes other than upon
          exercise of the Rights are not  sufficient  to permit the  exercise in
          full of the Rights,  or if any necessary  regulatory or other approval
          for such  issuance has not been  obtained by the Company,  the Company
          shall,  in lieu of issuing  shares of Common Stock in accordance  with
          SECTION  11(a)(ii)  hereof:  (A) determine the excess (the "Spread) of
          (1) the value of the shares of Common Stock issuable upon the exercise
          of a Right  (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 the Rights which have become
          void  pursuant to  paragraph  7(e) above) make  adequate  provision to
          substitute  for such  shares of Common  Stock,  upon  exercise  of the
          Rights,  (1) cash,  (2) a reduction in the Purchase  Price,  (3) other
          equity  securities  of the  Company  (including,  without  limitation,
          shares or units of shares of any series of preferred stock, (including
          the Units of  Preferred  Stock)  which the Board of  Directors  of the
          Company  has  deemed  to have the same  value as the  shares of Common
          Stock  (such  shares or units of  preferred  stock are  herein  called
          "preferred stock equivalents")), except to the extent that the Company
          has not obtained any necessary  regulatory approval for such issuance,
          (4) debt  securities  of the  Company,  except to the extent  that the
          Company has not obtained any  necessary  regulatory  approval for such
          issuance,  (5) other assets or (6) any  combination  of the foregoing,
          having an  aggregate  value  equal to the  Current  Value,  where such
          aggregate  value has been  determined by the Board of Directors of the
          Company  based upon the advice of a nationally  recognized  investment
          banking  firm  selected  by the  Board of  Directors  of the  Company;
          PROVIDED,  HOWEVER,  if the  Company  shall  not  have  made  adequate
          provision to deliver value  pursuant to clause (B) above within thirty
          (30) days following the later of (x) occurrence of a SECTION 11(a)(ii)
          Event,  and (y) the date on which the  Company's  right of  redemption
          pursuant  to  SECTION  23(a)  expires  (the later of (x) and (y) being
          referred to herein as the "SECTION 11(a)(iii) Trigger Date"), then the
          Company shall be obligated to deliver, upon the surrender for exercise
          of a Right and without requiring payment of the Purchase Price, shares
          of Common Stock (to the extent  available),  except to the extent that
          the  Company  has not  obtained  any  necessary  regulatory  or  other
          approval  for  such  issuance,  and  then,  if  necessary,  shares  or
          fractions of shares of preferred stock (to the extent available and if
          necessary regulatory or other approvals have been obtained), and then,
          if necessary cash,

                                       17
<PAGE>
          which shares and/or cash have an aggregate  value equal to the Spread.
          If, upon the  occurrence  of the SECTION  11(a)(ii)  Trigger  Date 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 to 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.  In the event
          of any such suspension,  the Company shall issue a public announcement
          stating  that the  exercisability  of the Rights has been  temporarily
          suspended,  as  well as a  public  announcement  at  such  time as the
          suspension  is no longer  in  effect.  For  purposes  of this  SECTION
          11(a)(iii),  the  value of the  shares of  Common  Stock  shall be the
          current  per share  market  price (as  determined  pursuant to SECTION
          11(d))  on the  SECTION  11(a)(ii)  Trigger  Date and the per share or
          fractional  value of any preferred 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 the event that the Company  shall fix a record date for the issuance
of rights,  options or  warrants  to all  holders  of Units of  Preferred  Stock
entitling them (for a period  expiring within 45 calendar days after such record
date) to subscribe  for or purchase  Units of Preferred  Stock (or shares having
the same rights,  privileges and preferences as the Preferred Stock ("equivalent
preferred  stock")) or securities  convertible  into Units of Preferred Stock or
equivalent  preferred stock at a price per Unit of Preferred Stock or equivalent
preferred  share  (or  having  a  conversion  price  per  share,  if a  security
convertible  into Units of Preferred Stock or equivalent  preferred  stock) less
than the then current per share  market  price of a Unit of Preferred  Stock (as
determined pursuant to SECTION 11(d)) on such record date, the Purchase Price to
be in effect  after such  record date shall be  determined  by  multiplying  the
Purchase  Price in effect  immediately  prior to such record date by a fraction,
the  numerator  of  which  shall be the  number  of  Units  of  Preferred  Stock
outstanding  on such  record  date plus the number of Units of  Preferred  Stock
which the  aggregate  offering  price of the total  number of Units of Preferred
Stock and/or  equivalent  preferred stock so to be offered (and/or the aggregate
initial  conversion price of the convertible  securities so to be offered) would
purchase at such current market price and the  denominator of which shall be the
number of Units of Preferred Stock outstanding on such

                                       18
<PAGE>
record  date plus the  number of  additional  Units of  Preferred  Stock  and/or
equivalent  preferred stock to be offered for  subscription or purchase (or into
which the convertible securities so to be offered are initially convertible). In
case such subscription price may be paid in a consideration part or all of which
shall be in a form other than cash, the value of such consideration  shall be as
determined  in good  faith  by the  Board of  Directors  of the  Company,  whose
determination  shall be described in a statement filed with the Rights Agent and
shall be binding on the Rights  Agent and the  holders of the  Rights.  Units of
Preferred  Stock owned by or held for the  account of the  Company  shall not be
deemed  outstanding  for the purpose of any such  computation.  Such  adjustment
shall be made  successively  whenever  such a record  date is fixed;  and in the
event that such  rights,  options or warrants  are not so issued,  the  Purchase
Price shall be adjusted to be the  Purchase  Price which would then be in effect
if such record date had not been fixed.

     (c) In case the Company shall fix a record date for a  distribution  to all
holders of Units of 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,  cash (other than a
regular  quarterly cash dividend) assets (other than a dividend payable in Units
of Preferred Stock but including any dividend payable in equity securities other
than  Preferred  Stock) or  subscription  rights or  warrants  (excluding  those
referred to in SECTION 11(d)  hereof),  the Purchase Price to be in effect after
such record date shall be determined by multiplying the Purchase Price in effect
immediately  prior to such  record date by a fraction,  the  numerator  of which
shall be the then  current per share  market  price (as  determined  pursuant to
SECTION 11(d)) of the Preferred  Stock on such record date, less the fair market
value (as  determined  in good faith by the Board of  Directors  of the Company,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent and shall be binding on the Rights  Agent and the holder of rights) of the
cash,  assets  or  evidences  of  indebtedness  to be  distributed  or  of  such
subscription rights or warrants distributable in respect of a share of Preferred
Stock and the  denominator of which shall be such current per share market price
(as determined  pursuant to SECTION 11(d)) of a share of Preferred  Stock.  Such
adjustments shall be made successively whenever such a record date is fixed; and
in the event that such  distribution  is not so made,  the Purchase  Price shall
again be adjusted to be the Purchase Price which would then be in effect if such
record date had not been fixed.

     (d)(i) For the purpose of any computation hereunder, the "current per share
market  price" of 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 thirty (30)  consecutive  Trading Days
(as such term is hereinafter  defined) immediately prior to such date; PROVIDED,
HOWEVER,  that in the event that the  "current  per share  market  price" of the
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 thirty  (30)  Trading  Days after the  ex-dividend  date for such
dividend or distribution,  or the record date for such subdivision,  combination
or reclassification, then,

                                       19
<PAGE>
and  in  each  such  case,  the  "current  per  share  market  price"  shall  be
appropriately   adjusted  to  reflect  the  "current  market  price"  per  share
equivalent  of such  Security.  The closing price for each day shall be the last
sale price,  regular  way, or, in case no such sale takes place on such day, the
average of the  closing  bid and asked  prices,  regular  way, in either case as
reported in the principal consolidated transaction reporting system with respect
to securities listed or admitted to trading on the Nasdaq National Market System
("NASDAQ")  or, if the  Security  is not  listed or  admitted  to trading on the
NASDAQ, as reported in the principal  consolidated  transaction reporting system
with respect to securities listed on the principal national  securities exchange
on which the  Security is listed or  admitted to trading or, if the  Security is
not listed or admitted to trading on any national securities exchange,  the last
quoted  price or, if not so  quoted,  the  average of the high bid and low asked
prices in the  over-the-counter  market, as reported by the NASDAQ 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. If on any such date no market maker is making
a market in the Security,  the "current per share market price" of such Security
on such  date as  determined  in good  faith by the  Board of  Directors  of the
Company as provided for above shall be used. The term "Trading Day" shall mean a
day on which the principal national securities exchange on which the Security is
listed or admitted to trading is open for the transaction of business or, if the
Security  is not  listed or  admitted  to  trading  on any  national  securities
exchange, a Business Day.

          (ii) For the purpose of any  computation  hereunder,  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 "current
     per share market price" of the Preferred  Stock cannot be determined in the
     manner  provided  above or if the  Preferred  Stock is not publicly held or
     listed or traded in a manner described in clause (i) of this SECTION 11(d),
     the  "current  per share  market  price" of the  Preferred  Stock  shall be
     conclusively  deemed to be an amount equal to $1,000 (as such amount may be
     appropriately adjusted for such events as stock splits, stock dividends and
     recapitalizations  with respect to shares of Company Common Stock occurring
     after the date of this  Agreement)  multiplied by the current  market price
     per share of Company Common Stock.  If shares of neither the Company Common
     Stock nor Preferred Stock is publicly held or so listed or traded, "current
     per share market  price" of the  Preferred  Stock shall mean the fair value
     per share as  determined  in good  faith by the Board of  Directors  of the
     Company whose  determination  shall be described in a statement  filed with
     the Rights  Agent and shall be binding on the Rights  Agent and the holders
     of the Rights.

     (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

                                       20
<PAGE>
SECTION  11  shall  be  made  to  the  nearest   cent  or  to  the  nearest  one
one-thousandth  of a share of Preferred Stock or one  one-hundredth of any other
share or security as the case may be. Notwithstanding the first sentence of this
SECTION 11(e), any adjustment required by this SECTION 11 shall be made no later
than the  earlier  of (i) three  years  from the date of the  transaction  which
requires such adjustment or (ii) the Expiration Date.

     (f) If as a result of an  adjustment  made  pursuant  to SECTION  11(a)(ii)
hereof,  the holder of any Rights thereafter  exercised shall become entitled to
receive any shares of capital stock of the Company or another  entity other than
Units of  Preferred  Stock,  thereafter  the  number  of such  other  shares  so
receivable  upon exercise of any Rights and the Purchase  Price thereof shall be
subject  to  adjustment  from  time to time in a manner  and on terms as  nearly
equivalent as practicable to the provisions  with respect to the Preferred Stock
contained in SECTION 11(a), (b), (c), (d), (e), (g), (h), (i), (j), (k), (l) and
(m),  and the  provisions  of SECTIONs  7, 9, 10, 13 and 14 with  respect to the
Preferred Stock shall apply on like terms to any such other shares.

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

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

     (i) The  Company  may elect on or after the date of any  adjustment  of the
Purchase  Price  to  adjust  the  number  of  Rights,  in  substitution  for any
adjustment  in the  number  of Units of  Preferred  Stock  purchasable  upon the
exercise of a Right. Each of the Rights outstanding after such adjustment of the
number of Rights shall be exercisable for the number of Units of Preferred Stock
for which a Right was exercisable  immediately  prior to such  adjustment.  Each
Right held of record  prior to such  adjustment  of the  number of Rights  shall
become that  number of Rights  (calculated  to the  nearest one  one-thousandth)
obtained  by  dividing  the  Purchase  Price  in  effect  immediately  prior  to
adjustment  of the Purchase  Price by the Purchase  Price in effect  immediately
after  adjustment  of the  Purchase  Price.  The  Company  shall  make a  public
announcement  of its  election  to adjust the number of Rights,  indicating  the
record date for the  adjustment,  and,  if known at the time,  the amount of the
adjustment  to be made.  This record date may be the date on which the  Purchase
Price is adjusted or any day thereafter,  but, if the Rights  Certificates  have
been  issued,  shall be at  least  ten days  later  than the date of the  public

                                       21
<PAGE>
announcement.  If Rights  Certificates have been issued, upon each adjustment of
the number of Rights  pursuant to this  SECTION  11(i),  the Company  shall,  as
promptly as practicable,  cause to be distributed to holders of record of Rights
Certificates  on such  record date Rights  Certificates  evidencing,  subject to
SECTION 14 hereof, the additional Rights to which such holders shall be entitled
as a result of such adjustment, or, at the option of the Company, shall cause to
be distributed to such holders of record in substitution and replacement for the
Rights  Certificates  held by such holders prior to the date of adjustment,  and
upon  surrender  thereof,  if required by the Company,  new Rights  Certificates
evidencing  all the Rights to which such  holders  shall be entitled  after such
adjustment.  Rights Certificates to be so 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 Rights  Certificates  on the record  date
specified in the public announcement.

     (j)  Irrespective  of any adjustment or change in the Purchase Price or the
number of Units of Preferred Stock issuable upon the exercise of the Rights, the
Rights  Certificates  theretofore and thereafter  issued may continue to express
the  Purchase  Price  per  Unit or  other  measure  and the  number  of Units of
Preferred Stock or other  securities  which were expressed in the initial Rights
Certificates issued hereunder.

     (k) Before  taking any action that would cause an  adjustment  reducing the
Purchase  Price  below  the then par value of the  number of Units of  Preferred
Stock of any other shares of capital stock issuable upon exercise of the Rights,
the Company  shall take any  corporate  action  which may, in the opinion of its
counsel,  be necessary  in order that the Company may validly and legally  issue
fully paid and  nonassessable  number of Units of Preferred  Stock or such other
shares of capital stock at such adjusted Purchase Price.

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

     (m)  Anything  in this  SECTION  11 to the  contrary  notwithstanding,  the
Company  shall be entitled to make such  reductions  in the Purchase  Price,  in
addition to those adjustments  expressly  required by this SECTION 11, as and to
the extent that it in its sole  discretion  shall  determine  to be advisable in
order that any (i)  consolidation  or subdivision of the Preferred  Stock,  (ii)
issuance wholly for cash of any Unit of Preferred Stock at less than the current
market price,  (iii) issuance  wholly for cash of Preferred  Stock or securities
which by their terms are convertible  into or exchangeable  for Preferred Stock,
(iv) dividends on Preferred Stock payable

                                       22
<PAGE>
in Preferred Stock or (v) issuance of rights, options or warrants referred to in
this  SECTION  11,  hereafter  made by the  Company  to  holders of Units of its
Preferred Stock shall not be taxable to such stockholders.

     (n) The Company  shall not, at any time after the  Distribution  Date,  (i)
consolidate  with any other Person  (other than a Subsidiary of the Company in a
transaction  which  complies  with SECTION  11(o)),  (ii) merge with or into any
other Person  (other than a  Subsidiary  of the Company in a  transaction  which
complies  with  SECTION  11(o)),  or  (iii)  sell or  transfer  (or  permit  any
Subsidiary  to  sell  or  transfer),   in  one  transaction,   or  a  series  of
transactions, assets or earning power aggregating more than 50% of the assets or
earning  power of the  Company  and its  Subsidiaries  (taken as a whole) to any
other Person or Persons (other than the Company  and/or any of its  Subsidiaries
in one or more  transactions  each of which complies with SECTION 11(o)), if (x)
at the time of or immediately after such consolidation, merger or sale there are
any  rights,   warrants  or  other  instruments  or  securities  outstanding  or
agreements in effect which would  substantially  diminish or otherwise eliminate
the  benefits   intended  to  be  afforded  by  the  Rights  or  (y)  prior  to,
simultaneously with or immediately after such consolidation, merger or sale, the
Person which constitutes, or would constitute the "Principal Party" for purposes
of  SECTION  13(a)  shall  have  distributed  or  otherwise  transferred  to its
stockholders  or other persons  holding an equity interest in such Person Rights
previously  owned  by  such  Person  or any of its  Affiliates  and  Associates;
PROVIDED,  HOWEVER,  this  SECTION  11(n)  shall not affect  the  ability of any
Subsidiary of the Company to  consolidate  with,  merge with or into, or sell or
transfer assets or earning power to, any other Subsidiary of the Company.

     (o) After the Distribution Date, the Company shall not, except as permitted
by SECTION 23 or SECTION 26, 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 otherwise eliminate the benefits intended
to be afforded by the Rights.

     (p) In the event  that,  at any time after the date of this  Agreement  and
prior to the  Distribution  Date,  the  Company  shall  (i)  declare  or pay any
dividend on outstanding shares of Common Stock payable in shares of Common Stock
or (ii) effect a subdivision,  combination or  consolidation of the Common Stock
(by  reclassification  or  otherwise  than by payment of  dividends in shares of
Common Stock) into a greater or lesser number of shares of Common Stock, then in
any such case the number of Rights  associated  with each share of Common  Stock
then   outstanding,   or   issuable   or   deliverable   thereafter,   shall  be
proportionately adjusted so that the number of Rights thereafter associated with
each such 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 such event by a fraction,  the  numerator of
which is the total  number of shares  of Common  Stock  outstanding  immediately
before such event and the  denominator of which is the total number of shares of
Common Stock outstanding  immediately after such event. The adjustments provided
for in this SECTION 11(p) shall be made successively whenever such a dividend is
declared  or  paid  or  such a  subdivision,  combination  or  consolidation  is
effected.

                                       23

SECTION 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF SHARES.

     Whenever  an  adjustment  is made as provided in SECTIONs 11 and 13 hereof,
the  Company  shall  promptly  (a)  prepare a  certificate  setting  forth  such
adjustment,  and a brief statement of the facts  accounting for such adjustment,
(b) file with the Rights  Agent and with each  transfer  agent for the shares of
Common Stock or Units of Preferred Stock a copy of such certificate and (c) mail
a brief  summary  thereof to each holder of a Rights  Certificate  in accordance
with SECTION 25 hereof.  Notwithstanding the foregoing sentence,  the failure by
the Company to make such  certification or give such notice shall not affect the
validity of or the force or effect of the requirement for such  adjustment.  The
Rights Agent shall be fully protected in relying on any such  certificate and on
any  adjustment  contained  therein and shall not be deemed to have knowledge of
such adjustment unless and until it shall have received such certificate.

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

     (a)  Except as  provided  in  SECTION  13(b)  hereof,  in the  event  that,
following a Shares  Acquisition  Date,  directly or indirectly,  (x) the Company
shall  consolidate  with, or merge with and into, any other Person (other than a
Subsidiary of the Company in a transaction  which complies with SECTION  11(o)),
and the Company  shall not be the  continuing or surviving  corporation  of such
consolidation or merger,  (y) any Person (other than a Subsidiary of the Company
in a transaction  which complies with SECTION 11(o)) shall  consolidate with the
Company,  or  merge  with  and into the  Company  and the  Company  shall be the
continuing  or surviving  corporation  of such  consolidation  or merger and, in
connection  with such  consolidation  or  merger,  all or part of the  shares of
Common Stock shall be changed into or exchanged for stock or other securities of
any other Person or cash or any other property, or (z) the Company shall sell or
otherwise  transfer (or one or more of its Subsidiaries  shall sell or otherwise
transfer) to any Person or Persons  (other than a Subsidiary of the Company in a
transaction  which complies with SECTION  11(o)),  in one or more  transactions,
directly or indirectly,  assets or earning power  aggregating 50% or more of the
assets or earning power of the Company and its Subsidiaries  (taken as a whole),
(any such event being a "SECTION 13 Event"), then, and in each such case, proper
provision shall be made so that: (i) each holder of a Right,  except as provided
in SECTION 7(e), shall  thereafter have the right to receive,  upon the exercise
thereof at the then current  Purchase  Price,  and in accordance  with the terms
hereof, 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),  which  shares  shall not be  subject  to any  liens,
encumbrances,  rights of first refusal,  transfer  restrictions or other adverse
claims,  as shall be equal to the result  obtained by dividing  the then current
Purchase  Price (which,  following the direct  occurrence of a SECTION 13 Event,
shall be the "Purchase  Price" for all purposes of this Agreement) by 50% of the
current per share market  price  (determined  pursuant to SECTION  11(d)) of the
shares of Common Stock of such Principal  Party on the date of  consummation  of
such SECTION 13 Event; (ii) such Principal Party shall thereafter be liable for,
and shall assume,  by virtue of such SECTION 13 Event,  all the  obligations and
duties of the

                                       24
<PAGE>
Company  pursuant to this  Agreement;  (iii) the term "Company"  shall,  for all
purposes  of this  Agreement,  thereafter  be deemed to refer to such  Principal
Party,  it being  specifically  intended that the provisions of SECTION 11 shall
apply only to such Principal Party  following the first  occurrence of a SECTION
13 Event;  (iv) such Principal Party shall take such steps  (including,  but not
limited  to,  the  reservation  of a  sufficient  number of shares of its Common
Stock) in connection  with the  consummation  of any such  transaction as may be
necessary to ensure that the  provisions of this Agreement  shall  thereafter be
applicable  to its  shares  of  Common  Stock  thereafter  deliverable  upon the
exercise of the Rights;  (v) the provisions of SECTION  11(a)(ii) shall be of no
further effect following the first occurrence of any SECTION 13 Event;  (vi) the
Purchase Price (as theretofore adjusted) and 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 paragraph 11(f) hereof to
reflect any changes  occurring in respect of the Common Stock of such  Principal
Party  after  the  occurrence  of such  SECTION  13 Event;  and  (vii)  upon any
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 which 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 all steps as
may be necessary to permit the  subsequent  exercise of the Rights in accordance
with the terms hereof for such cash, shares, rights and other property.

     (b) "Principal Party" shall mean:

          (i) in the case of any  transaction  described in clause (x) or (y) of
     the first sentence of SECTION  13(a),  (A) the Person that is the issuer of
     any  securities  into which shares of Company Common Stock are converted in
     such merger or  consolidation,  or, if there is more than one such  issuer,
     the issuer of shares of Common Stock that has the highest aggregate current
     market  price  (determined  pursuant  to  SECTION  11(d))  and  (B)  if  no
     securities are so issued, the Person that is the other party to such merger
     or consolidation, or, if there is more than one such Person, the Person the
     Common  Stock of which  has the  highest  aggregate  current  market  price
     (determined pursuant to SECTION 11(d)); and

          (ii) in the case of any  transaction  described  in clause  (z) of the
     first sentence of SECTION 13(a), the Person that is the party receiving the
     largest 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  transferred  pursuant to such transaction or transactions or
     if the Person  receiving the largest portion of the assets or earning power
     cannot be  determined,  whichever  Person the Common Stock of which has the
     highest  aggregate  current  market price  (determined  pursuant to SECTION
     11(d));  PROVIDED,  HOWEVER, that in any such case,

                                       25
<PAGE>
     (1) if the Common Stock of such Person is not at such time and has not been
     continuously  over  the  preceding  twelve-month  period  registered  under
     SECTION 12 of the Exchange Act ("Registered  Common Stock"), or such Person
     is not a corporation, and such Person is a direct or indirect Subsidiary of
     another Person that has  Registered  Common Stock  outstanding,  "Principal
     Party"  shall refer to such other  Person;  (2) if the Common Stock of such
     Person is not Registered  Common Stock or such Person is not a corporation,
     and such Person is a direct or indirect Subsidiary of another Person but is
     not a direct or indirect  Subsidiary of another Person which has Registered
     Common  Stock  outstanding,  "Principal  Party" shall refer to the ultimate
     parent entity of such  first-mentioned  Person;  (3) if the Common Stock of
     such  Person  is not  Registered  Common  Stock  or  such  Person  is not a
     corporation,  and such Person is directly or indirectly  controlled by more
     than one  Person,  and one or more of such  other  Persons  has  Registered
     Common  Stock  outstanding,  "Principal  Party" shall refer to whichever of
     such other Persons is the issuer of the Registered  Common Stock having the
     highest aggregate  current per share market price  (determined  pursuant to
     SECTION  11(d));  and  (4)  if the  Common  Stock  of  such  Person  is not
     Registered  Common  Stock or such  Person  is not a  corporation,  and such
     Person is directly or indirectly  controlled  by more than one Person,  and
     none of  such  other  Persons  has  Registered  Common  Stock  outstanding,
     "Principal  Party" shall refer to whichever  ultimate  parent entity is the
     corporation  having  the  greatest  stockholders'  equity  or,  if no  such
     ultimate parent entity is a corporation,  shall refer to whichever ultimate
     parent entity is the entity having the greatest net assets.

     (c) The Company shall not consummate any such  consolidation,  merger, sale
or  transfer  unless  the  Principal  Party  shall have a  sufficient  number of
authorized  shares of Common  Stock which have not been  issued or reserved  for
issuance to permit the  exercise in full of the Rights in  accordance  with this
SECTION 13, and unless prior thereto the Company and such Principal  Party shall
have  executed  and  delivered  to the  Rights  Agent a  supplemental  agreement
providing for the terms set forth in  paragraphs  (a) and (b) of this SECTION 13
and further providing that the Principal Party will:

          (i) (A) file on an appropriate form, as soon as practicable  following
     the  execution  of such  agreement,  a  registration  statement  under  the
     Securities  Act with  respect  to the  shares of Common  Stock  that may be
     acquired upon exercise of the Rights, (B) cause such registration statement
     to  remain  effective  (and to  include  a  prospectus  complying  with the
     requirements of the Securities  Act) until the Expiration  Date, and (C) as
     soon as  practicable  following the execution of such  agreement  take such
     action as may be required to ensure that any  acquisition of such shares of
     Common Stock upon the exercise of the Rights  complies with any  applicable
     state securities or "blue sky" laws;

          (ii) deliver to holders of the Rights historical  financial statements
     for the  Principal  Party and each of its  Affiliates  which  comply in all
     respects  with the  requirements  for  registration  on Form 10  under  the
     Exchange Act;

                                       26
<PAGE>
          (iii) 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; and

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

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

     (e) The provisions of this SECTION 13 shall  similarly  apply to successive
mergers  or  consolidations  or sales or other  transfers.  In the event  that a
SECTION  13 Event  shall  occur at any time  after the  occurrence  of a SECTION
11(a)(ii)  Event,  the Rights which have not  theretofore  been exercised  shall
thereafter become exercisable in the manner described in SECTION 13(a).

     SECTION 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

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

                                       27
<PAGE>
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 NASDAQ or, if the Rights are not listed or admitted to trading on
the NASDAQ,  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
Directors.  If on any such date no such  market  maker is making a market in the
Rights, the fair value of the Rights on such date as determined in good faith by
the Board of Directors of the Company shall be used.

     (b) The Company shall not be required to issue fractions of Preferred Stock
(other than fractions which are integral  multiples of one  one-thousandth  of a
share of  Preferred  Stock) or Common  Stock upon  exercise  of the Rights or to
distribute  certificates which evidence  fractional  Preferred Stock (other than
fractions  which are  integral  multiples  of one  one-thousandth  of a share of
Preferred  Stock) or Common  Stock.  Fractions  of  Preferred  Stock in integral
multiples of one  one-thousandth  of a share of Preferred Stock and fractions of
shares of Common  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 or Common 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 or fractional shares of Common
Stock, the Company shall pay to the registered holders of Rights Certificates at
the time such Rights are exercised as herein provided an amount in cash equal to
the same  fraction of the current  market  value of one share of Common Stock as
determined pursuant to SECTION 11(d).

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

     SECTION  15.  RIGHTS OF  ACTION.  All  rights of action in  respect of this
Agreement,  excepting  the  rights of action  given to the  Rights  Agent  under
SECTION 18 hereof, are vested in the respective registered holders of the Rights
Certificates  (and,  prior to the Distribution  Date, the registered  holders of
certificates  representing shares of Common Stock); and any registered holder of
any Rights  Certificate  (or,  prior to the  Distribution  Date,  a  certificate
representing shares of Common Stock), without the consent of the Rights Agent or
of the holder of any other Rights  Certificate  (or,  prior to the  Distribution
Date, of a certificate representing shares of

                                       28
<PAGE>
Common  Stock),  may,  in such  holder's  own behalf and for such  holder's  own
benefit,  enforce, and may institute and maintain any suit, action or proceeding
against the Company to enforce,  or otherwise  act in respect of, such  holder's
right to exercise the Rights evidenced by such Rights  Certificate in the manner
provided in such Rights Certificate and in this Agreement.  Without limiting the
foregoing or any remedies available to the holders of Rights, it is specifically
acknowledged that the holders of Rights would not have an adequate remedy at law
for any breach of this Agreement and will be entitled to specific performance of
the obligations  hereunder,  and injunctive  relief against actual or threatened
violations of the obligations of any Person subject to this Agreement.

     SECTION 16. AGREEMENT OF RIGHTS HOLDERS.

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

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

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

     (c) subject to SECTIONs  6(a) and 7(f)  hereof,  the Company and the Rights
Agent may deem and treat the person in whose name the  Rights  Certificate  (or,
prior to the  Distribution  Date, the associated  Common Stock  certificate)  is
registered  as the absolute  owner thereof and of the Rights  evidenced  thereby
(notwithstanding   any   notations   of  ownership  or  writing  on  the  Rights
Certificates  or the associated  Common 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; and

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

     SECTION 17. RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.

     No holder,  as such, of any Rights  Certificate  shall be entitled to vote,
receive  dividends  or be  deemed  for any  purpose  the  holder of the Units of
Preferred Stock or any other

                                       29
<PAGE>
securities of the Company which may at any time be issuable upon the exercise of
the Rights  represented  thereby,  nor shall anything contained herein or in any
Rights  Certificate  be  construed  to  confer  upon the  holder  of any  Rights
Certificate,  as such,  any of the rights of a stockholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
stockholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
stockholders  (except as provided in SECTION 25 hereof), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or Rights  evidenced by
such  Rights  Certificate  shall  have been  exercised  in  accordance  with the
provisions hereof.

     SECTION 18. CONCERNING THE RIGHTS AGENT.

     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, or willful misconduct on the part of
the Rights Agent, for any action taken,  suffered or omitted by the Rights Agent
in  connection  with  the  execution,  acceptance  and  administration  of  this
Agreement and the exercise and  performance  hereunder of its duties,  including
the costs and expenses of defending against and appealing any claim of liability
in the premises.  The indemnity provided herein shall survive the termination of
this Agreement and the expiration of the Rights. The costs and expenses incurred
in enforcing this right of indemnification shall be paid by the Company.

     The Rights  Agent may  conclusively  rely upon and 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 and the
exercise and  performance  of its duties  hereunder in reliance  upon any Rights
Certificate  or  certificate  for Units of  Preferred  Stock or shares of 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.  Notwithstanding  anything  in this
Agreement  to the  contrary,  in no event  shall the Rights  Agent be liable for
special,  indirect  or  consequential  loss or  damage  of any  kind  whatsoever
(including but not limited to lost  profits),  even if the Rights Agent has been
advised of the  likelihood of such loss or damage and  regardless of the form of
the action.

     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

                                       30
<PAGE>
corporation  succeeding to the stock transfer or corporate trust business of the
Rights Agent or any successor Rights Agent, shall be the successor to the Rights
Agent under this  Agreement  without the execution or filing of any paper or any
further  act on the  part  of any of the  parties  hereto,  provided  that  such
corporation  would be eligible for appointment as a successor Rights Agent under
the provisions of SECTION 21 hereof.  In case at the time such successor  Rights
Agent shall  succeed to the agency  created by this  Agreement any of the Rights
Certificates shall have been countersigned but not delivered, any such successor
Rights Agent may adopt the  countersignature of the predecessor Rights Agent and
deliver such Rights Certificates so countersigned;  and in case at that time any
of the Rights  Certificates  shall not have been  countersigned,  any  successor
Rights Agent may countersign such Rights  Certificates either in the name of the
predecessor  Rights Agent or in the name of the successor  Rights Agent;  and in
all such cases such Rights  Certificates  shall have the full force  provided in
the Rights Certificates and in this Agreement.

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

     SECTION 20. DUTIES OF RIGHTS AGENT.  The Rights Agent undertakes the duties
and  obligations  imposed  by  this  Agreement  upon  the  following  terms  and
conditions  and no  implied  duties  or  obligations  shall  be read  into  this
Agreement  against the Rights Agent, by all of which the Company and the holders
of Rights Certificates, by their acceptance thereof, shall be bound:

     (a) Before the Rights Agent acts or refrains  from  acting,  it may consult
with legal counsel of its choice (who may be legal counsel for the Company), and
the advice or opinion of such counsel  shall be full and complete  authorization
and  protection to the Rights Agent as to any action taken,  suffered or omitted
by it in good faith and in accordance with such advice or opinion.

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

                                       31
<PAGE>
     (c) The Rights Agent shall be liable hereunder to the Company and any other
Person only for its own gross negligence or willful misconduct.

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

     (e) The Rights Agent shall not be under any liability or  responsibility in
respect of the legality,  validity or  enforceability  of this  Agreement or the
execution and delivery  hereof  (except the due  execution  hereof by the Rights
Agent)  or in  respect  of  the  legality,  validity  or  enforceability  or the
execution of any Rights Certificate (except its countersignature thereof and has
actual  knowledge  of such  change  or  adjustment);  nor  shall it be liable or
responsible for any breach by the Company of any covenant or condition contained
in this Agreement or in any Rights Certificate;  nor shall it be responsible for
any change in the  exercisability  of the Rights  (including the Rights becoming
void pursuant to SECTION 11(a)(ii) hereof) or any adjustment in the terms of the
Rights (including the manner,  method or amount thereof) provided for in SECTION
3, 11, 13, 23 or 24, or the  ascertaining  of the  existence of facts that would
require any such change or  adjustment  (except  with respect to the exercise of
Rights  evidenced  by  Rights  Certificates  after  receipt  of the  certificate
described  in  SECTION  12  hereof or has  actual  knowledge  of 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 Units
of  Preferred  Stock to be  issued  pursuant  to this  Agreement  or any  Rights
Certificate  or as to whether any  Preferred  Stock or Common  Stock will,  when
issued, be validly authorized and issued, fully paid and nonassessable.

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

     (g)  The  Rights  Agent  is  hereby   authorized  and  directed  to  accept
instructions with respect to the administration, exercise and performance of its
duties  hereunder from any one of the Chairman of the Board, the Chief Executive
Officer,  the President,  any Vice President,  the Secretary or the Treasurer of
the  Company,  and to apply to such  officers  for  advice  or  instructions  in
connection  with its duties,  and it shall not be  responsible or liable for any
action  taken,  suffered  or  omitted  by it in good  faith in  accordance  with
instructions  of any such officer or for any delay in acting  while  waiting for
those instructions. Any application by the Rights Agent for written instructions
from the Company  may, at the option of the Rights  Agent,  set forth in writing
any action proposed to be taken or omitted by the Rights Agent under this Rights
Agreement  and the date on and/or after which such action shall be taken or such
omission shall be effective. The Rights Agent shall not be liable for any action
taken by, or  omission  of,  the  Rights  Agent in  accordance  with a  proposal
included in any such application on or after the date

                                       32
<PAGE>
specified  in such  application  (which  date  shall  not be less  than five (5)
Business Days after the date any officer of the Company  actually  received such
application,  unless  any such  officer  shall have  consented  in writing to an
earlier date) unless,  prior to taking any such action (or the effective date in
the  case  of an  omission),  the  Rights  Agent  shall  have  received  written
instructions in response to such  application  specifying the action to be taken
or omitted.

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

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

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

     (k) If, with respect to any Rights  Certificate  surrendered  to the Rights
Agent  for  exercise,   transfer,   split  up,  combination  or  exchange,   the
certification on the form of assignment or form of election to purchase,  as the
case may be, that the Rights  evidenced by the Rights  Certificate are not owned
by an Acquiring  Person,  or an Affiliate or Associate  thereof,  has either not
been completed or in any manner indicates any other response thereto, the Rights
Agent shall not take any further action with respect to such requested exercise,
transfer,  split up, combination or exchange,  without first consulting with the
Company.

     (l) The Rights  Agent  shall not be required to take notice or be deemed to
have  any  notice  of any  fact,  event  or  determination  (including,  without
limitation,  any dates or events defined in this Agreement or the designation of
any Person as an Acquiring Person,  Affiliate or Associate) under this Agreement
unless and until the Rights Agent shall be  specifically  notified in writing by
the Company of such fact, event or determination.

     SECTION 21. CHANGE OF RIGHTS AGENT.

     The Rights Agent or any successor Rights Agent may resign and be discharged
from its duties  under this  Agreement  upon thirty (30) days' notice in writing
mailed to the

                                       33
<PAGE>
Company and to each transfer agent of the Common Stock or Preferred Stock (as to
which the Rights Agent has  received  prior  written  notice) by  registered  or
certified  mail, and the Company shall mail notice thereof to the holders of the
Rights Certificates by first-class mail. The Company may remove the Rights Agent
or any successor  Rights Agent upon thirty (30) days' notice in writing,  mailed
to the Rights Agent or successor  Rights Agent,  as the case may be, and to each
transfer  agent of the Common Stock or  Preferred  Stock (as to which the Rights
Agent has received prior written notice) by registered or certified mail, and to
the holders of the Rights  Certificates by first-class mail. If the Rights Agent
shall resign or be removed or shall otherwise  become  incapable of acting,  the
Company shall appoint a successor to the Rights Agent. If the Company shall fail
to make such appointment within a period of thirty (30) days after giving notice
of such removal or after it has been notified in writing of such  resignation or
incapacity by the resigning or incapacitated  Rights Agent or by the holder of a
Rights  Certificate  (who shall,  with such notice,  submit such holder's Rights
Certificate  for inspection by the Company),  then the registered  holder of any
Rights  Certificate  may apply to any court of  competent  jurisdiction  for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court,  shall be a  corporation  organized and doing
business  under the laws of the  United  States  or of any  state of the  United
States, in good standing, authorized under such laws to exercise corporate trust
or stock transfer  powers,  and 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.  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 mail a
notice thereof in writing to the registered holders of the Rights  Certificates.
Failure to give any notice  provided  for in this  SECTION 21,  however,  or any
defect therein,  shall not affect the legality or validity of the resignation or
removal of the Rights Agent or the appointment of the successor Rights Agent, as
the case may be.

     SECTION 22. ISSUANCE OF NEW RIGHTS CERTIFICATES.

     Notwithstanding any of the provisions of this Agreement or of the Rights to
the  contrary,  the Company  may, at its option,  issue new Rights  Certificates
evidencing  Rights in such form as may be approved by its Board of  Directors to
reflect any adjustment or change in the Purchase Price and the number or kind or
class of shares or other  securities  or property  purchasable  under the Rights
Certificates  made in  accordance  with the  provisions  of this  Agreement.  In
addition,  in  connection  with the  issuance or sale of shares of Common  Stock
following the  Distribution  Date and prior to the Expiration  Date, the Company
(a) shall,  with respect to shares of Common Stock so issued or sold pursuant to
the exercise of stock options or under any employee  benefit plan or arrangement
or upon the  exercise,  conversion  or  exchange  of  securities  of the Company
currently outstanding or issued at any time in the future by the

                                       34
<PAGE>
Company and (b) may, in any other case, if deemed  necessary or  appropriate  by
the Board of Directors of the Company,  issue Rights  Certificates  representing
the  appropriate  number of Rights in  connection  with such  issuance  or sale;
PROVIDED,  HOWEVER, that (i) no such Rights Certificate shall be issued and this
sentence  shall be null and void AB INITIO  if,  and to the  extent  that,  such
issuance  or this  sentence  would  create a  significant  risk of or  result in
material  adverse  tax  consequences  to the  Company or the Person to whom such
Rights  Certificate  would be issued or would  create a  significant  risk of or
result in such options' or employee plans' or  arrangements'  failing to qualify
for  otherwise   available  special  tax  treatment  and  (ii)  no  such  Rights
Certificate shall be issued if, and to the extent that,  appropriate  adjustment
shall otherwise have been made in lieu of the issuance thereof.

     SECTION 23. REDEMPTION AND TERMINATION.

     (a) The Company may, at its option, upon approval by the Board of Directors
of the Company,  at any time prior to the earlier of (i) the Shares  Acquisition
Date or (ii) the Final  Expiration  Date redeem all but not less than all of the
then outstanding Rights at a redemption price of $0.01 per Right,  appropriately
adjusted  to reflect any stock  split,  stock  dividend  or similar  transaction
occurring  after  the date  hereof  (such  redemption  price  being  hereinafter
referred to as the "Redemption  Price"), and the Company may, at its option, pay
the  Redemption  Price  either in cash,  shares of  Common  Stock  (based on the
current per share market price thereof (as determined  pursuant to SECTION 11(d)
hereof) at the time of redemption),  or any other form of  consideration  deemed
appropriate by the Board of Directors. The redemption of the Rights by the Board
of Directors of the Company may be made effective at such time on such basis and
with  such  conditions  as the Board of  Directors  in its sole  discretion  may
establish.

     (b)  Immediately  upon the action of the Board of  Directors of the Company
ordering the redemption of the Rights  pursuant to paragraph (a) of this SECTION
23, and without any further action and without any notice, the right to exercise
the Rights will terminate and the only right thereafter of the holders of Rights
shall be to receive the Redemption Price. The Company shall promptly give public
notice of any such redemption;  PROVIDED,  HOWEVER, that the failure to give, or
any defect in, any such notice shall not affect the validity of such redemption.
Within  10 days  after  such  action  of the  Board of  Directors  ordering  the
redemption of the Rights,  the Company  shall give notice of such  redemption to
the Rights Agent and 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  will state the method by
which the payment of the Redemption Price will be made.  Neither the Company nor
any of its  Affiliates or Associates  may redeem,  acquire or purchase for value
any Rights at any time in any manner other than that  specifically  set forth in
this SECTION 23 or in SECTION 24 hereof,  and other than in connection  with the
purchase of shares of Common Stock prior to the Distribution Date.

                                       35
<PAGE>
     (c)  Notwithstanding  anything contained in this Agreement to the contrary,
the Rights  shall not be  exercisable  pursuant to SECTION 7(a) at any time when
the Rights are redeemable hereunder.

     SECTION 24. EXCHANGE.

     (a) The Company,  at its option, upon approval by the Board of Directors of
the  Company,  at any time after any Person  becomes an  Acquiring  Person,  may
exchange all or part of the then outstanding and exercisable Rights (which shall
not include  Rights that have become void pursuant to the  provisions of SECTION
7(e) hereof) for shares of Common  Stock at an exchange  ratio equal to (subject
to adjustment to reflect stock splits,  stock dividends and similar transactions
occurring after the date hereof),  at the election and in the sole discretion of
the Board of  Directors  or the  Company,  either (i) that  number  obtained  by
dividing the Purchase Price by the then current per share market price per share
of Common  Stock on the  earlier of (A) the date on which any Person  becomes an
Acquiring  Person  or (B) the date on which a tender  or  exchange  offer by any
Person  (other than the Company,  any  Subsidiary  of the Company,  any employee
benefit plan maintained by the Company or any of its Subsidiaries or any trustee
or  fiduciary  with  respect  to such  plan  acting in such  capacity)  is first
published or sent or given  within the meaning of Rule  14d-4(a) of the Exchange
Act Regulations or any successor rule, if upon consummation  thereof such Person
would be the Beneficial  Owner of 15% or more of the shares of Common Stock then
outstanding  or (ii) one share of Common  Stock per Right (such  exchange  ratio
being   hereinafter   referred  to  as  the  "SECTION  24(a)  Exchange  Ratio").
Notwithstanding  the foregoing,  the Company may not effect such exchange at any
time after any Person  (other than the Company,  any  Subsidiary of the Company,
any employee benefit plan maintained by the Company or any of its  Subsidiaries,
or any trustee or fiduciary with respect to such plan acting in such  capacity),
together  with  all  Affiliates  and  Associates  of such  Person,  becomes  the
Beneficial Owner of 50% or more of the shares of Common Stock then outstanding.

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

                                       36
<PAGE>
     (c) In the event  that the  number of  shares  of  Common  Stock  which are
authorized by the Company's  Certificate of Incorporation but not outstanding or
reserved for issuance  for purposes  other than upon  exercise of the Rights are
not  sufficient to permit any exchange of Rights as  contemplated  in accordance
with this SECTION 24, the Company shall take all such action as may be necessary
to authorize additional shares of Common Stock for issuance upon exchange of the
Rights or make adequate provision to substitute (1) cash, (2) Units of Preferred
Stock or other shares or fractions of shares of Preferred  Stock or other equity
securities of the Company, (3) debt securities of the Company, (4) other assets,
or (5) any combination of the foregoing,  having an aggregate value equal to the
Adjustment  Spread,  where such aggregate value has been determined by the Board
of Directors of the Company. To the extent that the Company determines that some
action need be taken pursuant to subsection (a) of this SECTION 24, the Board of
Directors may temporarily  suspend the exercisability of the Rights for a period
of up to sixty  (60) days  following  the date on which the event  described  in
SECTION  24(a)  shall  have  occurred,  in order to seek  any  authorization  of
additional  shares  of Common  Stock or other  securities  and/or to decide  the
appropriate  form of distribution to be made pursuant to the above provision and
to determine the value thereof. In the event of any such suspension, the Company
shall issue a public announcement  stating that the exercisability of the Rights
has been temporarily suspended.

     (d) The Company shall not be required to issue fractions smaller than or to
distribute  certificates  which  evidence  fractions  smaller  than one share of
Common Stock. In lieu thereof,  the Company shall pay to the registered  holders
of the Rights  Certificates  with regard to which such  fractional  shares would
otherwise  be  issuable  an amount  in cash  equal to the same  fraction  of the
current market value (as determined  pursuant to SECTION 11(d)(i) hereof) of one
share of Common Stock.

     SECTION 25. NOTICE OF CERTAIN EVENTS.

     (a) In case the Company  shall  propose (i) to pay any dividend  payable in
stock of any class to the  holders of its  Preferred  Stock or to make any other
distribution  to the  holders  of its  Preferred  Stock  (other  than a  regular
quarterly cash  dividend),  (ii) to offer to the holders of its Preferred  Stock
rights or  warrants to  subscribe  for or to purchase  any  additional  Units 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 of outstanding Preferred
Stock), (iv) to effect any consolidation or merger into or with any other Person
(other than a Subsidiary  of the Company in a  transaction  which  complies with
SECTION  11(o)),  or to effect any sale or other  transfer  (or to permit one or
more of its Subsidiaries to effect any sale or other  transfer),  in one or more
transactions,  of 50% or more of the assets or earning  power of the Company and
its  Subsidiaries  (taken as a whole)  to, any other  Person,  (v) to effect the
liquidation, dissolution or winding up of the Company, or (vi) to declare or pay
any dividend on the Common Stock  payable in shares of Common Stock or to effect
a subdivision,  combination or  consolidation  of the shares of Common Stock (by
reclassification  or otherwise  than by payment of dividends in shares of Common
Stock), then, in each such case,

                                       37
<PAGE>
the Company  shall give to each holder of a Rights  Certificate,  in  accordance
with SECTION 26 hereof,  a notice of such proposed  action,  which shall specify

rights or warrants, or the date on which such  reclassification,  consolidation,
merger, sale, transfer, liquidation, dissolution, or winding up is to take place
and the date of  participation  therein  by the  holders of the shares of Common
Stock and/or  shares of 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  ten (10) days  prior to the  record  date for  determining
holders of the shares of Preferred Stock for purposes of such action, and in the
case of any such other  action,  at least ten (10) days prior to the date of the
taking of such  proposed  action  or the date of  participation  therein  by the
holders  of the  shares of  Common  Stock  and/or  shares  of  Preferred  Stock,
whichever shall be the earlier.

     (b) In case any of the events set forth in SECTION  11(a)(ii)  hereof shall
occur,  then the Company shall as soon as  practicable  thereafter  give to each
holder of a Rights  Certificate,  in accordance with SECTION 26 hereof, a notice
of the occurrence of such event,  which notice shall describe such event and the
consequences of such event to holders of Rights under SECTION  11(a)(ii) hereof.
In the event any Person becomes an Acquiring  Person,  the Company will promptly
notify the Rights Agent thereof.

the last sentence of Rule 13d-3(d)(1)(i) of

other parties and (y) not subject the Board of Directors to any liability to the

                         (Pursuant to SECTION 151 of the
                        Delaware General Corporation Law)

                                   ----------

     Burr-Brown  Corporation,  a corporation  organized  and existing  under the
General  Corporation  Law of the  State  of  Delaware  (hereinafter  called  the
"Corporation"),  hereby  certifies that the following  resolution was adopted by
the Board of  Directors  of the  Corporation  as  required by SECTION 151 of the
General  Corporation  Law of the State of Delaware at a meeting  duly called and
held on July 23, 1999;

     RESOLVED, that pursuant to the authority granted to and vested in the Board
of Directors of the Corporation  (hereinafter called the "Board of Directors" or
the  "Board")  in  accordance   with  the  provisions  of  the   Certificate  of
Incorporation,  as amended,  the Board of Directors  hereby  creates a series of
Preferred  Stock,  par value  $.01 per share  (the  "Preferred  Stock"),  of the
Corporation and hereby states the  designation  and number of shares,  and fixes
the relative rights, preferences, and limitations thereof as follows:

     Series A Junior Participating Preferred Stock:

     1. DESIGNATION AND AMOUNT. The shares of such series shall be designated as
"Series A Junior Participating Preferred Stock" (the "Series A Preferred Stock")
and the number of shares  constituting the Series A Preferred Stock shall be one
hundred thousand (100,000).  Such number of shares may be increased or decreased
by resolution of the Board of Directors;

                                       A-1
<PAGE>
provided,  that no  decrease  shall  reduce  the  number  of  shares of Series A
Preferred Stock to a number less than the number of shares then outstanding plus
the number of shares  reserved  for issuance  upon the  exercise of  outstanding
options, rights or warrants or upon the conversion of any outstanding securities
issued by the Corporation convertible into Series A Preferred Stock.

     2. DIVIDENDS AND DISTRIBUTIONS.

     (a)  Subject  to the  rights of the  holders of any shares of any series of
Preferred  Stock (or any similar stock) ranking prior and superior to the Series
A Preferred Stock with respect to dividends,  each holder of a share of Series A
Preferred  Stock,  in preference  to the holders of shares of Common Stock,  par
value $0.01 per share (the "Common Stock"), of the Corporation, and of any other
junior  stock,  shall be  entitled  to  receive,  when  declared by the Board of
Directors out of funds legally  available for the purpose,  quarterly  dividends
payable in cash on the last business day of March, June,  September and December
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 Series A Preferred  Stock,
in an amount per share  (rounded to the nearest  cent) equal to,  subject to the
provision for adjustment  hereinafter set forth,  One Thousand (1,000) times the
aggregate per share amount of all cash dividends, and One Thousand (1,000) times
the  aggregate per share amount  (payable in kind) of all non-cash  dividends or
other distributions,  other than a dividend payable in shares of Common Stock or
a subdivision of the outstanding shares of Common Stock (by  reclassification or
otherwise),  declared  on the  Common  Stock  since  the  immediately  preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment  Date,  since  the first  issuance  of a share or  fraction  of Series A
Preferred  Stock. In the event the Corporation  shall at any time declare or pay
any dividend on the Common Stock payable in shares of Common Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the amount to which  holders  of shares of Series A  Preferred
Stock were entitled immediately prior to such event under the preceding sentence
shall be adjusted by  multiplying  such amount by a fraction,  the  numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

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

                                       A-2
<PAGE>
     (c) Dividends  shall begin to accrue and be cumulative on each  outstanding
share of Series A  Participating  Preferred  Stock from the  Quarterly  Dividend
Payment  Date  next  preceding  the  date of issue  of such  share  of  Series A
Participating  Preferred Stock,  unless the date of issue of such share is prior
to the record date for the first Quarterly  Dividend Payment Date, in which case
dividends  on such share  shall  begin to accrue  from the date of issue of such
share, or unless the date of issue is a Quarterly  Dividend Payment Date or is a
date after the record date for the  determination of holders of shares of Series
A  Preferred  Stock  entitled to receive a  quarterly  dividend  and before such
Quarterly  Dividend Payment Date, in either of which events such dividends shall
begin to accrue and be cumulative  from such  Quarterly  Dividend  Payment Date.
Accrued but unpaid  dividends  shall not bear  interest.  Dividends  paid on the
shares of Series A Preferred  Stock in an amount  less than the total  amount of
such dividends at the time accrued and payable on such shares shall be allocated
pro  rata  on a  share-  by-share  basis  among  all  such  shares  at the  time
outstanding.  The Board of Directors may fix a record date for the determination
of holders of shares of Series A Preferred  Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be not more
than 60 days prior to the date fixed for the payment thereof.

     3. VOTING RIGHTS.  The holders of shares of Series A Preferred  Stock shall
have the following voting rights:

     (a) Subject to the provision for  adjustment  hereinafter  set forth,  each
share of Series A  Preferred  Stock  shall  entitle  the  holder  thereof to One
Thousand (1,000) votes on all matters submitted to a vote of the stockholders of
the Corporation.  In the event the Corporation  shall at any time declare or pay
any dividend on the Common Stock payable in shares of Common Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the  number of votes per share to which  holders  of shares of
Series A Preferred Stock were entitled  immediately prior to such event shall be
adjusted by multiplying such number by a fraction, the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

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

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

                                       A-3

     4. CERTAIN RESTRICTIONS.

     (a)  Whenever  quarterly  dividends  or other  dividends  or  distributions
payable on the Series A 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 A Preferred Stock  outstanding  shall have
been paid in full, the Corporation shall not:

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

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

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

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

     (b) The  Corporation  shall not permit any subsidiary of the Corporation to
purchase  or  otherwise  acquire  for  consideration  any shares of stock of the
Corporation unless the Corporation could, under paragraph (a) of this Section 4,
purchase or otherwise acquire such shares at such time and in such manner.

     5. REACQUIRED  SHARES.  Any shares of Series A Preferred Stock purchased or
otherwise  acquired by the Corporation in any manner whatsoever shall be retired
and cancelled promptly after the acquisition thereof. All such shares shall upon
their cancellation  become authorized but unissued shares of Preferred Stock and
may be  reissued  as part of a new  series of  Preferred  Stock  subject  to the
conditions and restrictions on issuance set forth herein,  in the Certificate of
Incorporation,  or in any other Certificate of Designations creating a series of
Preferred Stock or any similar stock or as otherwise required by law.

                                       A-4
<PAGE>
     6. LIQUIDATION, DISSOLUTION OR WINDING UP.

     (a) Upon any liquidation,  dissolution or winding up of the Corporation, no
distribution  shall be made (i) to the holders of shares of stock ranking junior
(either as to dividends or upon  liquidation,  dissolution or winding up) to the
Series A Preferred Stock unless,  prior thereto, the holders of shares of Series
A Preferred Stock shall have received One Thousand  Dollars  ($1,000) per share,
plus an amount equal to accrued and unpaid dividends and distributions  thereon,
whether or not declared, to the date of such payment,  provided that the holders
of shares of Series A Preferred  Stock shall be entitled to receive an aggregate
amount per share, subject to the provision for adjustment hereinafter set forth,
equal to 1,000 times the aggregate amount to be distributed per share to holders
of shares of Common Stock (the "Series A  Liquidation  Preference"),  or (ii) to
the holders of shares of stock  ranking on a parity  (either as to  dividends or
upon liquidation,  dissolution or winding up) with the Series A Preferred Stock,
except  distributions  made ratably on the Series A Preferred Stock and all such
parity stock in proportion to the total amounts to which the holders of all such
shares are entitled  upon such  liquidation,  dissolution  or winding up. In the
event the  Corporation  shall at any time  declare  or pay any  dividend  on the
Common  Stock  payable in shares of Common  Stock,  or effect a  subdivision  or
combination  or  consolidation  of the  outstanding  shares of Common  Stock (by
reclassification  or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common  Stock,  then in each
such case the aggregate  amount to which holders of shares of Series A Preferred
Stock were entitled  immediately prior to such event under the proviso in clause
(i) of the preceding  sentence shall be adjusted by multiplying such amount by a
fraction  the  numerator  of which is the  number  of  shares  of  Common  Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event (the "Common Adjustment").

     (b) In the event,  however,  that there are not sufficient assets available
to  permit  payment  in full to the  Series  A  Liquidation  Preference  and the
liquidation  preferences of all other series of Preferred  Stock,  if any, which
rank on a parity  with the Series A  Participating  Preferred  Stock,  then such
remaining  assets  shall be  distributed  ratably to the  holders of such parity
shares in proportion to their respective liquidation preferences.

     7. CONSOLIDATION, MERGER, ETC. In case the Corporation shall enter into any
consolidation,  merger,  combination or other transaction in which the shares of
Common Stock are exchanged for or changed into other stock or  securities,  cash
and/or  any  other  property,  then in any such  case  each  share  of  Series A
Preferred Stock shall at the same time be similarly exchanged or changed into an
amount per share, subject to the provision for adjustment hereinafter set forth,
equal to One Thousand (1,000) times the aggregate  amount of stock,  securities,
cash and/or any other property (payable in kind), as the case may be, into which
or for which each share of Common  Stock is changed or  exchanged.  In the event
the  Corporation  shall at any time  declare or pay any  dividend  on the Common
Stock payable in shares of Common Stock,  or effect a subdivision or combination
or consolidation of the outstanding shares of Common Stock (by  reclassification
or  otherwise  than by payment of a dividend  in shares of Common  Stock) into a
greater or lesser number of shares of Common  Stock,  then in each such case the
amount set forth in the  preceding  sentence  with  respect to the  exchange  or
change of

                                       A-5
<PAGE>
shares of Series A Preferred Stock shall be adjusted by multiplying  such amount
by a fraction,  the  numerator  of which is the number of shares of Common Stock
outstanding  immediately  after such event and the  denominator  of which is the
number of shares of Common Stock that were outstanding immediately prior to such
event.

     8. NO  REDEMPTION.  The  shares of Series A  Preferred  Stock  shall not be
subject to redemption by the Corporation.

     9. RANK.  The Series A  Preferred  Stock shall  rank,  with  respect to the
payment  of  dividends  and  the   distribution  of  assets  upon   liquidation,
dissolution or winding up, junior to all series of the  Corporation's  Preferred
Stock,  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 Preferred Stock are
outstanding,  the Certificate of Incorporation  of the Corporation  shall not be
amended  in any  manner  which  would  materially  alter or change  the  powers,
preferences  or special  rights of the Series A Preferred  Stock so as to affect
them  adversely  without  the  affirmative  vote of the  holders  of at  least a
majority  of  the  outstanding  shares  of  Series  A  Preferred  Stock,  voting
separately as a single class.

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

     IN WITNESS  WHEREOF,  this  Certificate of Designation has been executed on
behalf of the Corporation by its President and Chief  Executive  Officer and its
corporate seal attested by its Secretary this 9th day of August, 1999.

"Company")  declared a dividend of one common stock  purchase  right (a "Right")
for each outstanding share of Common Stock (the "Common Stock"), par value $0.01
per  share,  of  the  Company  outstanding  on  August  11,  1989.  The  initial
description  and terms of the  Rights  were as set  forth in a Rights  Agreement
dated as of July 21, 1989 (the "Original Rights Agreement")  between the Company
and Valley  National Bank of Arizona,  N.A., as Rights Agent.  On July 23, 1999,
the Board of Directors of the Company  authorized and approved the amendment and
restatement  in its entirety of the Original  Rights  Agreement  (as amended and
restated,  the "Rights Agreement").  Set forth below is a summary of the Rights,
as amended, and the Rights Agreement.

     Each Right now entitles the registered  holder to purchase from the Company
one  one-thousandth  of a share (a  "Unit")  of  Series  A Junior  Participating
Preferred Stock, par value $0.01 per share (the "Series A Preferred Stock"),  of
the Company at a price of $220.00 per Unit (the  "Purchase  Price"),  subject to
adjustment  (or other  securities  or  property  of the  Company,  as  described
herein).

     Until the  earlier to occur of (i) the close of  business on the first date
of a public  announcement  that a person or group of  affiliated  or  associated
persons (an "Acquiring Person") has acquired beneficial ownership of 15% or more
of the outstanding  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  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 such outstanding 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  with a copy of the Summary of Rights
attached thereto.

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

                                       C-1

reference.  Until the Distribution Date (or earlier  redemption or expiration of
the Rights),  the surrender for transfer of any  certificates  for Common Stock,
even  without such  notation or a copy of this Summary of Rights being  attached
thereto,  will also  constitute the transfer of the Rights  associated  with the
Common Stock represented by such certificate.  As soon as practicable  following
the  Distribution  Date,  separate  certificates  evidencing the Rights ("Rights
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 Rights Certificates
alone will evidence the Rights.

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

     The Purchase Price payable,  and the number of Units 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) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Stock, (ii) upon the grant to holders of the Units of Preferred Stock of certain
rights or warrants to subscribe  for or purchase  Units of Preferred  Stock at a
price, or securities convertible into Units of Preferred Stock with a conversion
price,  less than the then current market price of the Units of Preferred  Stock
or (iii) upon the  distribution  to holders of the Units of  Preferred  Stock of
evidences of indebtedness or assets  (excluding  regular periodic cash dividends
paid out of  earnings  or retained  earnings  or  dividends  payable in Units of
Preferred  Stock)  or of  subscription  rights or  warrants  (other  than  those
referred to above).

     The number of outstanding Rights and the number of Units of Preferred Stock
issuable upon exercise of each Right are also subject to adjustment in the event
of a stock split of the Common  Stock or a stock  dividend  on the Common  Stock
payable in Common Stock or subdivisions,  consolidations  or combinations of the
Common Stock occurring, in any such case, prior to the Distribution Date.

     Units of Preferred Stock  purchasable  upon exercise of the Rights will not
be redeemable. Each Unit of Preferred Stock will be entitled to a dividend equal
to (and having  priority over) any dividend  declared per share of Common Stock.
In the event of liquidation,  each Unit of Preferred Stock will be entitled to a
payment equal to (and having priority over) any payment made per share of Common
Stock. Each Unit of Preferred Stock will have one vote, voting together with the
Common  Stock.  Finally,  in the  event of any  merger,  consolidation  or other
transaction  in which  shares  of  Common  Stock  are  exchanged,  each  Unit of
Preferred  Stock  will be  entitled  to  receive  an amount  equal to the amount
received  per share of Common  Stock.  These  rights are  protected by customary
antidilution provisions.

                                       C-2
<PAGE>
     Because of the nature of the dividend,  liquidation and voting rights,  the
value of each Unit of Preferred  Stock  purchasable  upon exercise of the Rights
should approximate the value of one share of Common Stock.

     In the event  that,  after the Rights  become  exercisable,  the Company is
acquired in a merger or other business combination transaction with an Acquiring
Person or an affiliate  thereof,  or 50% or more of its  consolidated  assets or
earning power are sold to an Acquiring  Person or an affiliate  thereof,  proper
provision will be made so that each holder of a Right will  thereafter  have the
right to receive,  upon exercise  thereof at the then current  exercise price of
the Rights, that number of shares of common stock of the acquiring company which
at the time of such  transaction  will  have a market  value  of two  times  the
exercise price of the Rights.

     In the event that any person or group of affiliated  or associated  persons
becomes the beneficial owner of 15% or more of the outstanding  shares of Common
Stock, proper provision shall be made so that each holder of a Right, other than
Rights  beneficially  owned by the Acquiring  Person  (which will  thereafter be
void),  will  thereafter  have the right to receive upon exercise that number of
shares of Common Stock (or cash,  other  securities or property) having a market
value of two times the exercise price of the Rights.

     At any time after the  acquisition  by a person or group of  affiliated  or
associated  persons of  beneficial  ownership of 15% or more of the  outstanding
shares of Common Stock and prior to the  acquisition  by such person or group of
50% or more of the  outstanding  Common  Stock,  the Board of  Directors  of the
Company may exchange all or part of the Rights  (other than Rights owned by such
person or group,  which have become  void) for shares of Common  Stock (or other
securities,  assets or property) at an exchange  ratio  (subject to  adjustment)
which  shall  equal,  subject to  adjustment  to  reflect  stock  splits,  stock
dividends and similar transactions  occurring after the date hereof,  either (A)
that number  obtained by dividing  the  Purchase  Price by the then  current per
share  market  price per share of Common Stock on the earlier of (i) the date on
which any Person becomes an Acquiring  Person or (ii) the date on which a tender
or exchange offer is announced by any Person, if upon consummation  thereof such
Person  would be the  Beneficial  Owner of 15% or more of the  shares of Company
Common Stock then  outstanding  or (B) one share of Common  Stock per Right,  as
determined by the Board of Directors in its sole discretion.

     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 will be issued
(other than fractions which 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 market  price of the Units of  Preferred  Stock on the
last trading day prior to the date of exercise.

                                       C-3

     At any time  prior to the date  that a  person  or group of  affiliated  or
associated  persons  acquire  beneficial   ownership  of  15%  or  more  of  the
outstanding  Common Stock,  the Board of Directors of the Company may redeem the
Rights in whole, but not in part, 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.  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.  The Rights are also redeemable  under
other circumstances as specified in the Rights Agreement.

     The terms of the Rights may be  amended  by the Board of  Directors  of the
Company  without the  consent of the holders of the Rights  except that from and
after a Distribution  Date no such amendment may adversely  affect the interests
of the holders of the Rights.

     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 or other distributions.

     The Rights  have  certain  anti-takeover  effects.  The  Rights  will cause
substantial  dilution to a person or group that  attempts to acquire the Company
on terms not approved by the Company's Board of Directors, except pursuant to an
offer conditioned on a substantial  number of rights being acquired.  The Rights
should not interfere with any merger or other business  combination  approved by
the Board of Directors  because the Rights may be redeemed by the Company at the
Redemption Price prior to the occurrence of a Distribution Date.

     A copy of the  Rights  Agreement  has been filed  with the  Securities  and
Exchange  Commission as an Exhibit to an amendment to Registration  Statement on
Form 8-A, and also as an Exhibit to a Current  Report on Form 8-K. A copy of the
Rights  Agreement  is available  free of charge from the  Company.  This summary
description  of the Rights does not purport to be complete  and is  qualified in
its entirety by reference to the Rights Agreement,  which is hereby incorporated
herein by reference.
