Item 5.  OTHER EVENTS.

     On August 19, 1997 the Board of Directors of Oak Technology, Inc. (the 
"Company") declared a dividend of one preferred share purchase right (a 
"Right") for each outstanding share of Common Stock (the "Common Stock"), par 
value $0.001 per share (the "Common Stock"), of the Company.  The dividend is 
payable on August 29, 1997 (the "Record Date") to the stockholders of record 
on that date.  Each Right entitles the registered holder to purchase from the 
Company one one-thousandth of a share (a "Unit") of Series A Junior 
Participating Preferred Stock, par value $0.001 per share (the "Preferred 
Stock"), of the Company at a price of $60.00 per Unit (the "Purchase Price"), 
subject to adjustment.  The description and terms of the Rights are set forth 
in a Rights Agreement dated as of August 19, 1997 (the "Rights Agreement") 
between the Company and BankBoston, N.A., as Rights Agent (the "Rights 
Agent").

     Initially, the Rights will attach to all certificates representing 
shares of outstanding Common Stock, and no separate Rights Certificates will 
be distributed.  The Rights will separate from the Common Stock and the 
distribution date (the "Distribution Date") will occur upon the earlier of 
(i) 10 days following a public announcement that a person or group of 
affiliated or associated persons (an "Acquiring Person") have 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 
Continuing 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 this 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 after the Record Date, upon transfer or new 
issuance of Common Stock will contain a notation incorporating the Rights 
Agreement by reference.  Until the Distribution Date (or earlier redemption 
or expiration of the Rights), the surrender for transfer of any certificates 
for Common Stock, outstanding as of the Record Date, even without such 
notation or a copy of this Summary of Rights being attached thereto, will 
also constitute the transfer of the Rights associated with the Common 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 19, 2007 (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 Rights are also subject to adjustment in 
the event of a stock split of the Common Stock or a stock divi-


                                       2.

dend 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 an 
aggregate dividend of 1,000 times the dividend declared per share of Common 
Stock.  In the event of liquidation, the holders of the Units of Preferred 
Stock will be entitled to an aggregate payment of 1,000 times the payment 
made per share of Common Stock.  Each Unit of Preferred Stock will have 1,000 
votes, 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 1,000 
times the amount received per share of Common Stock.  These rights are 
protected by customary antidilution provisions.

     Because of the nature of the dividend, liquidation and voting rights, 
the value of the Preferred Stock, the Units of Preferred Stock purchasable 
upon exercise of each 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 Rights 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 Units of Preferred 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 Continuing Directors of 
the Company may exchange the Rights (other than Rights owned by such person 
or group which have become void), in whole or in part, at an exchange ratio 
of one share of Common Stock (or the number of Units of Preferred Stock 
having equivalent market value) per Right (subject to adjustment).

     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 
shares 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.

     At any time within ten (10) business days after a person or group of 
affiliated or associated persons acquire beneficial ownership of 15% or more 
of the outstanding Common Stock (unless the Continuing Directors extend such 
ten-day period), the Board of Directors of the Company may redeem the Rights 
in whole, but not in part, at a price of $.01 per Right (the "Redemption 
Price"), upon the approval of a majority of the Continuing Directors.  The 
redemption of the rights may be made effective at such time on such basis and 
with such conditions as the Board of Directors, upon the approval of the 
Continuing 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.


                                       3.
<PAGE>

     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 upon the approval of 
a majority of the Continuing Directors 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.

     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 since the Rights may be 
redeemed by the Company at the Redemption Price prior to the occurrence of a 
Distribution Date.

     The Rights Agreement, dated as of August 19, 1997, between the Company 
and the Rights Agent, specifying the terms of the Rights, is attached hereto 
as an exhibit and is incorporated herein by reference.  The foregoing 
description of the Rights is qualified in its entirety by reference to such 
exhibit.

                                RIGHTS AGREEMENT


          RIGHTS AGREEMENT, dated as of August 19, 1997, between OAK 
TECHNOLOGY, INC., a Delaware corporation (the "Company"), and BankBoston, 
N.A., a national banking association (the "Rights Agent").

          WHEREAS, effective August 19, 1997 (the "Rights Dividend 
Declaration Date"), the Board of Directors authorized and declared a 
distribution 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 19, 1997 (the "Record Date"), 
each Right initially representing the right to purchase one one-thousandth of 
a share (a "Unit") of Preferred Stock (as hereinafter defined) upon the terms 
and subject to the conditions herein set forth, and has further authorized 
and directed the issuance of one Right 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).

          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 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,
     then such Person shall be deemed to be an "Acquiring Person" thereunder;
     and


                                       1.
<PAGE>

          (ii) if the Board of Directors of the Company determines (upon
     approval by a majority of the Continuing Directors (as such term is
     hereinafter defined)) in good faith that a Person who would otherwise be an
     "Acquiring Person" as defined pursuant to the foregoing provisions of this

co-Rights Agent.

          Section 3.  ISSUE OF RIGHTS CERTIFICATES.  (a)  Until the earlier 
of (i) the Close of Business on the Shares Acquisition Date and (ii) the 
Close of Business on the tenth Business Day (or such later date as may be 
determined by action of the Company's Board of Directors upon approval by a 
majority of the Continuing Directors prior to such time as any Person becomes 
an Acquiring Person and of which the Company will give the Rights Agent 
prompt written notice) after the date that a tender or exchange offer by any 
Person (other than the Company, any Subsidiary of the Company, any employee 
benefit plan of the Company or of any Subsidiary of the Company or any entity 
holding shares of Common Stock for or pursuant to the terms of any such plan) 
is first published or sent or given within the meaning of Rule 14d-4(a) of 
the Exchange Act Regulations or any successor rule or of the first public 
announcement of the intention of any Person (other than the Company, any 
Subsidiary of the Company, any employee benefit plan of the Company or of any 
Subsidiary of the Company or any entity holding shares of Common Stock for or 
pursuant to the terms of any such plan) to commence, a tender or exchange 
offer, if upon consummation thereof such Person would be the Beneficial Owner 
of 15% or more of the shares of Company Common Stock then outstanding (the 
earlier of (i) and (ii) above being the "Distribution Date"), (x) the Rights 
will be evidenced (subject to the provisions of Section 3(b) hereof) by the 
certificates for shares of Common 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 transferable only in connection with the 
transfer of shares of Common Stock.  As soon as practicable after the 
Distribution Date, the Company will notify the Rights Agent thereof and the 
Company will prepare and execute, the Rights Agent will countersign, and the 
Company will send or cause to be sent (and the Rights Agent will, if 
requested, send) by first-class, insured, postage-prepaid mail, to each 
record holder of shares of 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 will send a copy of a Summary of Rights to Purchase Preferred Stock, in
substantially the form of Exhibit C hereto (the "Summary of Rights"), by first-
class, postage-prepaid mail, to each record holder of shares of Common Stock as

holders thereof together with a copy of the 


                                       6.
<PAGE>

Summary of Rights attached thereto. Until the Distribution Date (or 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 earliest 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
          between Oak Technology, Inc. and BankBoston, N.A., dated as
          of August 19, 1997 (the "Rights Agreement"), the terms of
          which are hereby incorporated herein by reference and a copy
          of which is on file at the principal executive offices of
          Oak Technology, Inc.  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.  Oak Technology, Inc. will mail to the
          holder of this certificate a copy of the Rights Agreement
          without charge after receipt of a written request therefor. 
          Under certain circumstances, 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.

          Section 4.     FORM OF RIGHTS CERTIFICATES.  (a)  The Rights 
Certificates (and the forms of election to purchase Units of Preferred Stock 
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, 


                                       7.
<PAGE>

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 the number of 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 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 a majority of the Continuing 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 between Oak Technology, Inc. and
          BankBoston, N.A., as Rights Agent, dated as of August 19, 1997 (the
          "Rights Agreement").  Accordingly, this Rights Certificate and the
          Rights represented hereby may become null and void in the
          circumstances specified in Section 7(e) of the Rights Agreement.

          Section 5.  COUNTERSIGNATURE AND REGISTRATION.  (a)  The Rights 
Certificates shall be executed on behalf of the Company by its Chairman of 
the Board or any of its Vice Presidents, 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 


                                       8.
<PAGE>

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. (a)  
Subject to the provisions of Sections 4(b), 7(e) and 14 hereof, at any time 
after the Close of Business on the Distribution Date, and at or prior to the 
Close of Business on the Expiration Date, any Rights Certificate or Rights 
Certificates may be transferred, split up, combined or exchanged for another 
Rights Certificate or Rights Certificates, entitling the registered holder to 
purchase a like number of 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.

other securities or property, 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 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 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

Certificate, registered in such name or names as may be designated by such

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 


                                      10.
<PAGE>

necessary so that such other securities, cash and/or other property are 
available for distribution by the Rights Agent, if and when appropriate.

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


                                      11.
<PAGE>

purchased or acquired by the Company otherwise than upon the exercise 
thereof.  The Rights Agent shall deliver all cancelled Rights Certificates 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 Units of Preferred Stock 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 of 1933, as amended (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 


                                      12.
<PAGE>

time of delivery of the certificates for such Units of Preferred Stock 
(subject to payment of the Purchase Price), be duly and validly authorized 
and issued and fully paid and non-assessable.

          (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 and FURTHER PROVIDED, 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 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 OF SHARES OR 
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.


                                      13.
<PAGE>

          (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), (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,


                                      14.
<PAGE>

     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 $5,000,000, 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 each holder of a Right, except as provided in Section 
7(e) hereof, shall thereafter have the right to receive for each Right, upon 
exercise thereof in accordance with the terms of this Agreement and payment 
of the then-current Total Exercise Price, in lieu of the number of Units of 
Preferred Stock for which a Right was exercisable immediately prior to the 
first occurrence of a Section 11(a)(ii) Event, such number of Units of 
Preferred Stock as shall equal the result obtained by multiplying the 
then-current Purchase Price by the then number of Units of Preferred Stock 
for which a Right was exercisable (or would have been exercisable if the 
Distribution Date had occurred) immediately prior to the first occurrence of 
a Triggering Event, and dividing that product by 50% of the current per share 
market price (determined pursuant to Section 11(d) hereof) for shares of 
Common Stock on the date of occurrence 


                                      15.
<PAGE>

of the Triggering Event (such number of Units of Preferred Stock being 
hereinafter referred to as the "Adjustment Shares").

          (iii) In the event that the number of Units of Preferred Stock which
     are authorized by the Company's Amended and Restated Certificate of
     Incorporation but not outstanding or reserved for issuance for purposes
     other than upon exercise of the Rights are not sufficient to permit the
     exercise in full of the Rights, or if any necessary regulatory approval for
     such issuance has not been obtained by the Company, the Company shall, in
     lieu of issuing Units of Preferred Stock in accordance with Section
     11(a)(ii) hereof, upon approval by a majority of the Continuing Directors: 
     (A) determine the excess of (1) the value of the Units of Preferred Stock
     issuable upon the exercise of a Right (the "Current Value") over (2) the
     Purchase Price (such excess being referred to as the "Spread") and (B) with
     respect to each Right, make adequate provision to substitute for such Units
     of Preferred 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, Common Stock or shares or units of shares
     of any series of preferred stock which the Board of Directors of the
     Company, upon approval by a majority of the Continuing Directors, has
     deemed to have the same value as the Units of Preferred 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, upon approval by a majority of the
     Continuing Directors, based upon the advice of a nationally recognized
     investment banking firm selected by the Board of Directors of the Company,
     upon approval by a majority of the Continuing Directors; PROVIDED,
     HOWEVER, if the Company shall not have made adequate provision to deliver
     value pursuant to clause (B) above within thirty (30) days following the
     later of (x) 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, Units of Preferred Stock (to the extent available), and
     then, if necessary, cash, which Units and/or cash have an aggregate value
     equal to the Spread. 

          (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 shares")) or securities convertible into Units 
of Preferred Stock or equivalent preferred shares 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 shares)


                                      16.
<PAGE>

less than the then current per share market price of the 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 shares so to be offered (and/or the 
aggregate initial conversion price of the convertible securities so to be 
offered) would purchase at such current market price and the denominator of 
which shall be the number of Units of Preferred Stock outstanding on such 
record date plus the number of additional Units of Preferred Stock and/or 
equivalent preferred shares to be offered for subscription or purchase (or 
into which the convertible securities so to be offered are initially 
convertible).  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 a majority of the 
Continuing 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 a majority of the Continuing 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 

                                      17.
<PAGE>

     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, 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 a majority of the Continuing Directors.  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 


                                      18.
<PAGE>

     Preferred Stock shall mean the fair value per share as determined in good 
     faith by the Board of Directors of the Company, upon approval by a majority
     of the Continuing Directors, whose determination shall be described in a 
     statement filed with the Rights Agent and shall be binding on the Rights 
     Agent and the holders of the Rights.

          (e)  No adjustment in the Purchase Price shall be required unless 
such adjustment would require an increase or decrease of at least 1% in the 
Purchase Price; PROVIDED, HOWEVER, that any adjustments which by reason of 
this Section 11(e) are not required to be made shall be carried forward and 
taken into account in any subsequent adjustment.  All calculations under this 
Section 11 shall be made to the nearest cent or to the nearest one 
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 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 Units of 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 


                                      19.
<PAGE>

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 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 and the number of Units of 
Preferred Stock 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 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 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 


                                      20.
<PAGE>

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 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 


                                      21.
<PAGE>

such case the number of Units of Preferred Stock purchasable after such event 
upon proper exercise of each Right shall be determined by multiplying the 
number of Units of Preferred Stock so purchasable immediately prior to such 
event by a fraction, the numerator of which is the number of shares of Common 
Stock outstanding immediately before such event and the denominator of which 
is the 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.

          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, such number of 
validly authorized and issued, fully paid and non-assessable shares of Common 
Stock of the Principal Party, 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 (1) multiplying the then 
current Purchase Price by the number of Units of Preferred Stock for which a 
Right is exercisable immediately prior to the first occurrence 


                                      22.
<PAGE>

of a Section 13 Event (or, if a Section 11(a)(ii) Event has occurred prior to 
the first occurrence of a Section 13 Event, multiplying the number of such 
Units for which a Right would be exercisable hereunder but for the occurrence 
of such Section 11(a)(ii) Event by the Purchase Price which would be in 
effect hereunder but for such first occurrence) and (2) dividing that product 
(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 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; and (v) the 
provisions of Section 11(a)(ii) shall be of no further effect following the 
first occurrence of any Section 13 Event.

          (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, (1) if the Common
     Stock of such Person is not at such time and have 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 


                                      23.
<PAGE>

     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; and

           (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.

          (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 



                                      24.
<PAGE>

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 Rights.  For the purposes of this Section 
14(a), the current market value of a whole Rights shall be the closing price 
of the Rights for the Trading Day immediately prior to the date on which such 
fractional Rights would have been otherwise issuable.  The closing price for 
any day shall be the last sale price, regular way, or, in case no such sale 
takes place on such day, the average of the closing bid and asked prices, 
regular way, in either case as reported in the principal consolidated 
transaction reporting system with respect to securities listed or admitted to 
trading on the 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, upon approval by a majority of the Continuing Directors, 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) upon exercise of the Rights or 
to distribute certificates which evidence fractional Preferred Stock (other 


                                      25.
<PAGE>

than fractions which are integral multiples of one one-thousandth of a share 
of Preferred Stock).  Fractions of Preferred Stock in integral multiples of 
one one-thousandth of a share of Preferred Stock may, at the election of the 
Company, be evidenced by depositary receipts, pursuant to an appropriate 
agreement between the Company and a depositary selected by it; PROVIDED, 
HOWEVER, that such agreement shall provide that the holders of such 
depositary receipts shall have all the rights, privileges and preferences to 
which they are entitled as beneficial owners of the Preferred Stock 
represented by such depositary receipts.  In lieu of fractional shares of 
Preferred Stock that are not integral multiples of one one-thousandth of a 
share of Preferred Stock, the Company shall pay to the registered holders of 
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 a share of Preferred Stock as determined pursuant to Section 11(d).

          (c)  The holder of a Right by the acceptance of the Right expressly 
waives his right to receive any fractional Rights or any fractional shares 
upon exercise 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 
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;


                                      26.
<PAGE>

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

          Section 18.  CONCERNING THE RIGHTS AGENT.  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.


                                      27.

          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.

          Section 19.  MERGER OR CONSOLIDATION OR CHANGE OF NAME OF RIGHTS 
AGENT.  (a)  Any corporation into which the Rights Agent or any successor 
Rights Agent may be merged or with which it may be consolidated, or any 
corporation resulting from any merger or consolidation to which the Rights 
Agent or any successor Rights Agent shall be a party, or any corporation 
succeeding to the stock transfer or corporate trust 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 


                                      28.
<PAGE>

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 the Chairman of the Board, any Vice President 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.

          (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 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.


                                      29.
<PAGE>

          (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 the Chairman of the Board, any Vice President or 
the Secretary of the Company, and to apply to such officers for advice or 
instructions in connection with its duties, and it shall not be 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 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 


                                      30.
<PAGE>

further action with respect to such requested exercise, transfer, split up, 
combination or exchange, without first consulting with the Company.

          Section 21.  CHANGE OF RIGHTS AGENT.  The Rights Agent or any 
successor Rights Agent may resign and be discharged from its duties under 
this Agreement upon thirty (30) days' notice in writing mailed to the Company 
and to each transfer agent of the 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 upon approval by a 
majority of the Continuing 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.


                                      31.
<PAGE>

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 
Company and (b) may, in any other case, if deemed necessary or appropriate by 
the Board of Directors of the Company, upon approval by a majority of the 
Continuing Directors, 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 a majority of the Continuing Directors, 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 the then outstanding 
Rights at a redemption price of $.01 per Right, appropriately adjusted to 
reflect any stock split, stock dividend or similar transaction occurring 
after the date hereof (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; PROVIDED that, notwithstanding 
anything to the contrary contained in this Section 23(a), the Company may not 
take any action pursuant to this Section 23(a) unless (x) at the time of the 
action of the Board of Directors of the Company approving such redemption and 
the form of payment of the Redemption Price, there are then in office not 
less than two Continuing Directors and (y) such action is approved by a 
majority of the Continuing Directors then in office.  The redemption of the 
Rights by the Board of Directors may be made effective at such time on such 
basis and with such conditions as a majority of the Continuing Directors in 
its sole discretion may establish.

          (b)  Immediately upon the action of a majority of the Continuing 
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 a majority of the Continuing 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 



                                      32.
<PAGE>

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.

          (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 a majority of the Continuing Directors, 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(f) hereof) for Units of 
Preferred Stock at an exchange ratio equal to, subject to adjustment to 
reflect stock splits, stock dividends and similar transactions occurring 
after the date hereof, that number obtained by dividing the Purchase Price by 
the then current per share market price per Unit of Preferred Stock on the 
earlier of (i) the date on which any Person becomes an Acquiring Person and 
(ii) 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 
Company Common Stock then outstanding (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 Units of 
Preferred 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 


                                      33.
<PAGE>

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(f) hereof) 
held by each holder of Rights.

          (c)  In the event that the number of shares of Preferred 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 34, the Company shall take all 
such action as may be necessary to authorize additional shares of Preferred 
Stock for issuance upon exchange of the Rights or make adequate provision to 
substitute (1) cash, (2) Company Common 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 a 
majority of the Continuing Directors. 

          (d)  The Company shall not be required to issue fractions smaller 
than or to distribute certificates which evidence fractions smaller than one 
one-thousandth of a share of Preferred Stock.  In lieu thereof, the Company 
shall pay to the registered holders of the Rights Certificates with regard to 
which such fractional Units would otherwise be issuable an amount in cash 
equal to the same fraction of the current market value (as determined 
pursuant to Section 11(c)(i) hereof) of one Unit of Preferred 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, 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 the record 
date for the purposes of such stock dividend, or 


                                      34.
<PAGE>

distribution of rights or warrants, or the date on which such 
reclassification, consolidation, merger, sale, transfer, liquidation, 
dissolution, or winding up is to take place and the date of participation 
therein by the holders of the shares of Common Stock and/or Units 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 Units 
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 Units 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.

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

the Purchase Price, the Redemption Price, any time periods herein specified, 
and any other term hereof, any such supplement or amendment to be evidenced

of Common Stock outstanding at any particular time, including for purposes of 
determining the particular percentage of such outstanding shares of Common 
Stock of which any Person is the Beneficial Owner, shall be made in 
accordance with the last sentence of Rule 13d-3(d)(1)(i) of the General Rules 
and Regulations under the Exchange Act.  The Board of Directors of the 
Company shall have the exclusive power and authority to administer this 
Agreement and to exercise all rights and powers specifically granted to the 
Board, or the Company, or as may be necessary or advisable in the 
administration of this Agreement, including, without limitation, the right 
and power to (i) interpret the provisions of this Agreement and (ii) make all 
determinations deemed necessary or advisable for the administration of this 
Agreement (including a determination to redeem or not redeem the Rights or to 
amend the Agreement).  All such actions, calculations, interpretations and 
determinations (including, for purposes of clause (y) below, all omissions 
with respect to the foregoing), which are done or made 


                                      36.

by the Board in good faith, shall (x) be final, conclusive and binding on the 
Company, the Rights Agent, the holders of the Rights Certificates and all 
other parties and (y) not subject the Board or the Continuing Directors to 
any liability to the holders of the Rights.

          Section 30.  BENEFITS OF THIS AGREEMENT.  Nothing in this Agreement 
shall be construed to give to any person or corporation other than the 
Company, the Rights Agent and the registered holders of the Rights 
Certificates (and, prior to the Distribution Date, shares of Common Stock) 
any legal or equitable right, remedy or claim under this Agreement; but this 
Agreement shall be for the sole and exclusive benefit of the Company, the 
Rights Agent and the registered holders of the Rights Certificates (and, 
prior to the Distribution Date, shares of Common Stock).

          Section 31.  SEVERABILITY.  If any term, provision, covenant or 
restriction of this Agreement is held by a court of competent jurisdiction or 
other authority to be invalid, void or unenforceable, the remainder of the 
terms, provisions, covenants and restrictions of this Agreement shall remain 
in full force and effect and shall in no way be affected, impaired or 
invalidated; PROVIDED, HOWEVER, that notwithstanding anything in this 
Agreement to the contrary, if any such term, provision, covenant or 
restriction is held by such court or authority to be invalid, void or 
unenforceable and the Board of Directors of the Company, upon approval by a 
majority of the Continuing Directors, determines in its good faith judgment 
that severing the invalid language from this Agreement would adversely affect 
the purpose or effect of this Agreement, the right of redemption set forth in 
Section 23 hereof shall be reinstated and shall not expire until the tenth 
business day following the date of such determination by the Board of 
Directors of the Company.

          Section 32.  GOVERNING LAW.  This Agreement and each Rights 
Certificate issued hereunder shall be deemed to be a contract made under the 
laws of the State of Delaware and for all purposes shall be governed by and 
construed in accordance with the laws of such State applicable to contracts 
to be made and performed entirely within such State.

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

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

                              OAK TECHNOLOGY, INC.

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

                       ----------------------------------


          OAK TECHNOLOGY, INC., 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 at a meeting duly called and held on August 18, 1997;

          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, the Board of Directors hereby creates a series 
of Preferred Stock, par value $.001 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:

          Section 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 four hundred thousand (400,000).  Such number of 
shares may be increased or decreased by resolution of the Board of Directors; 
PROVIDED,


                                      A-1
<PAGE>

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.

          Section 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 one one-thousandth (1/1,000) of a share of Series A Preferred 
     Stock (a "Unit"), in preference to the holders of shares of Common 
     Stock, par value $.001 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 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 Unit of 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, 1,000 times the aggregate per share 
     amount of all cash dividends, and 1,000 times the aggregate per share 
     amount (payable in kind) of all non-cash dividends or other 
     distributions, other than a dividend payable in shares of Common Stock 
     or a subdivision of the outstanding shares of Common Stock (by 
     reclassification or otherwise), declared on the Common Stock since the 
     immediately preceding Quarterly Dividend Payment Date or, with respect 
     to the first Quarterly Dividend Payment Date, since the first issuance 
     of a Unit 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 clause (b) of the preceding sentence shall be adjusted 
     by multiplying such amount by a fraction, the numerator of which is the 
     number of shares of Common Stock outstanding immediately after such 
     event and the denominator of which is the number of shares of Common 
     Stock that were outstanding immediately prior to such event.
     
          (B)  The Corporation shall declare a dividend or distribution on 
     the Units 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 


                                      A-2
<PAGE>

     $1.00 per Unit on the Series A Preferred Stock shall nevertheless be 
     payable on such subsequent Quarterly Dividend Payment Date.
     
          (C)  Dividends shall begin to accrue and be cumulative on each 
     outstanding Unit of Series A Participating Preferred Stock from the 
     Quarterly Dividend Payment Date next preceding the date of issue of such 
     Unit of Series A Participating Preferred Stock, unless the date of issue 
     of such Unit is prior to the record date for the first Quarterly 
     Dividend Payment Date, in which case dividends on such Unit shall begin 
     to accrue from the date of issue of such Unit, 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 Units 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 Units of Series A Preferred Stock in an amount less than the 
     total amount of such dividends at the time accrued and payable on such 
     Units shall be allocated pro rata on a Unit-by-Unit basis among all such 
     Units at the time outstanding.  The Board of Directors may fix a record 
     date for the determination of holders of Units 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.
     
          Section 3.  VOTING RIGHTS.  The holders of Units of Series A 
Preferred Stock shall have the following voting rights:

          (A)  Subject to the provision for adjustment hereinafter set forth, 
     each Unit of Series A Preferred Stock shall entitle the holder thereof 
     to 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 Unit to which holders of Units 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 Units 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.


                                      A-3
<PAGE>

          (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.

          Section 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 Units 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 Units 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 Units 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.


                                      A-4
<PAGE>

          (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.

          Section 5.  REACQUIRED UNITS.  Any Units 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 Units shall upon their cancellation become authorized but 
unissued Units 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.

          Section 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.

          (A)  Upon any liquidation, dissolution or winding up of the
     Corporation, no distribution shall be made (1) 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 Units of Series A Preferred Stock shall have
     received $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 Units 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, or (2) 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 Units of
     Series A Preferred Stock were entitled immediately prior to such event
     under the proviso in clause (1) of the preceding sentence shall be adjusted
     by multiplying such amount by a fraction the numerator of which is the
     number of shares of Common Stock outstanding immediately after such event
     and the denominator of which is the number of shares of Common Stock that
     were outstanding immediately prior to such event.

          (B)  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 


                                      A-5
<PAGE>

     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.  

          Section 7.  CONSOLIDATION, MERGER, ETC.  In case the 
Corporation shall enter into any consolidation, merger, combination or 
other transaction in which the Units 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 Unit, subject to the provision for adjustment hereinafter set forth, 
equal to 1,000 times the aggregate amount of stock, securities, cash 
and/or any other property (payable in kind), as the case may be, into 
which or for which each share of Common Stock is changed or exchanged. 
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 
Units 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.

          Section 8.  NO REDEMPTION.  The Units of Series A Preferred 
Stock shall not be redeemable.

          Section 9.  RANK.  The Series A Preferred Stock shall rank, 
with respect to the payment of dividends and the distribution of assets, 
junior to all series of any other class of the Corporation's Preferred 
Stock.

          Section 10.  AMENDMENT.  The Amended and Restated 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 Units of Series A Preferred Stock, voting 
together as a single class.

like tenor and date evidencing Rights entitling the holder to purchase a like 
aggregate number of Series A Preferred Stock as the Rights evidenced by the 
Rights Certificate or Rights Certificates surrendered shall have entitled 
such holder to purchase.  If this Rights Certificate shall be exercised in 
part, the holder shall be entitled to receive upon surrender hereof another 
Rights Certificate or Rights Certificates for the number of whole Rights not

                              OAK TECHNOLOGY, INC.

                          SUMMARY OF RIGHTS TO PURCHASE
                       SHARES OF SERIES A PREFERRED STOCK


          On August 19, 1997, the Board of Directors of Oak Technology, Inc. 
(the "Company") declared a dividend of one preferred share purchase right (a 
"Right") for each outstanding share of Common Stock (the "Common Stock"), par 
value $.001 per share, of the Company.  The dividend is payable on August 29, 
1997 (the "Record Date") to the stockholders of record on that date.  Each 
Right entitles the registered holder to purchase from the Company one 
one-thousandth of a share (a "Unit") of Series A Junior Participating 
Preferred Stock, par value $.001 per share (the "Series A Preferred Stock"), 
of the Company at a price of $60.00 per Unit (the "Purchase Price"), subject 
to adjustment.  The description and terms of the Rights are set forth in a 
Rights Agreement dated as of August 19, 1997 (the "Rights Agreement") between 
the Company and BankBoston, N.A., as Rights Agent (the "Rights Agent").

          Until the earlier to occur of (i) 10 days following a public 
announcement that a person or group of affiliated or associated persons (an 
"Acquiring Person") have 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 Continuing 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 this 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 after the Record Date, upon transfer or 
new issuance of Common Stock will contain a notation incorporating the Rights 
Agreement by reference.  Until the Distribution Date (or earlier redemption 
or expiration of the Rights), the surrender for transfer of any certificates 
for Common Stock, outstanding as of the Record Date, even without such 
notation or a copy of this Summary of Rights being attached thereto, will 
also constitute the transfer of the Rights associated with the Common 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


                                      C-1
<PAGE>

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 19, 2007 (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 Series A 
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 Series A Preferred Stock, (ii) upon the grant to 
holders of the Units of Series A Preferred Stock of certain rights or 
warrants to subscribe for or purchase Units of Series A Preferred Stock at a 
price, or securities convertible into Units of Series A Preferred Stock with 
a conversion price, less than the then current market price of the Units of 
Series A Preferred Stock or (iii) upon the distribution to holders of the 
Units of Series A 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 Series A 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 Series 
A Preferred Stock issuable upon exercise of each Rights 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 Series A PreFerred Stock purchasable upon exercise of the 
Rights will not be redeemable.  Each Unit of Series A PreFerred Stock will be 
entitled to an aggregate dividend of 1,000 times the dividend declared per 
share of Common Stock.  In the event of liquidation, the holders of the Units 
of Series A PreFerred Stock will be entitled to an aggregate payment of 1,000 
times the payment made per share of Common Stock.  Each Unit of Series A 
PreFerred Stock will have 1,000 votes, 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 Series A PreFerred 
Stock will be entitled to receive 1,000 times the amount received per share 
of Common Stock. These rights are protected by customary antidilution 
provisions.

          Because of the nature of the dividend, liquidation and voting 
rights, the value of the Series A PreFerred Stock, the Units of Series A 
PreFerred Stock purchasable upon exercise of each Rights should approximate 
the value of one share of Common Stock.


                                      C-2
<PAGE>

          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 Rights 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 Units of Series A PreFerred 
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 
Continuing 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 
Units of Series A PreFerred Stock 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, 
that number obtained by dividing the Purchase Price by the then current per 
share market price per Unit of Series A PreFerred Stock on the earlier of (i) 
the date on which any Person becomes an Acquiring Person and (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.  

          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 Series A PreFerred Stock 
will be issued (other than fractions which are integral multiples of one 
one-thousandth of a shares of Series A 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 Series A PreFerred Stock on the last trading day prior to the date 
of exercise.

          At any time within ten (10) business days after a person or group 
of affiliated or associated persons acquire beneficial ownership of 15% or 
more of the outstanding Common Stock (unless the Continuing Directors extends 
such ten-day period), the Board of Directors of the Company may redeem the 
Rights in whole, but not in part, at a price of $.01 per Right (the 
"Redemption Price"), upon the approval of a majority of the Continuing 
Directors.  The redemption 


                                      C-3
<PAGE>

of the rights may be made effective at such time on such basis and with such 
conditions as the Directors, upon the approval of the Continuing 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 upon the 
approval of a majority of the Continuing Directors 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.

          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 since 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 a Registration Statement on Form 
8-A.  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.
