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


         On September 9, 1998, the Board of Directors of Elantec  Semiconductor,
Inc. (the  "Company")  declared a dividend of one preferred share purchase right
(a "Right")  for each  outstanding  share of common  stock,  par value $0.01 per
share  (the  "Common  Shares"),  of the  Company.  The  dividend  is  payable to
stockholders of record on September 21, 1998 (the "Record  Date").  In addition,
one Right shall be issued with each Common  Share that becomes  outstanding  (i)
between the Record Date and the  earliest of the  Distribution  Date (as defined
below),  the date the Rights are redeemed and the date the Rights expire or (ii)
following  the  Distribution  Date and prior to the date the Rights are redeemed
and the date the Rights  expire,  pursuant to the  exercise of stock  options or
under any employee  plan or  arrangement  or upon the  exercise,  conversion  or
exchange of other  securities  of the  Corporation,  which options or securities
were  outstanding  prior to the  Distribution  Date.  Each  Right  entitles  the
registered  holder to purchase from the Company one  two-hundredth of a share of
Series A Junior  Participating  Preferred  Stock, par value $0.01 per share (the
"Preferred Shares"),  of the Company, at a price of $25.00 per one two-hundredth
of a  Preferred  Share  (the  "Purchase  Price"),  subject  to  adjustment.  The
description and terms of the Rights are set forth in a Rights Agreement  between
the Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent.

         Until  the  earlier  to  occur  of  (i)  10  days  following  a  public
announcement  or  disclosure  that a person or group of affiliated or associated
persons (an "Acquiring  Person"),  has acquired  beneficial  ownership of 20% or
more of the  outstanding  Common  Shares or (ii) 10 business days (or such later
date as may be determined by action of the Board of Directors  prior to the time
a person or group becomes an Acquiring Person), following the announcement of an
intention to make a tender  offer or exchange  offer the  consummation  of which
would result in a person or group  becoming an Acquiring  Person (the earlier of
such dates being called the "Distribution  Date"), the Rights will be evidenced,
with  respect  to any of the Common  Share  certificates  outstanding  as of the
Record Date,  by such Common Share  certificates  with a copy of this Summary of
Rights attached thereto.  No person or group shall become an Acquiring Person if
the Board of Directors of the Company  determines in good faith that a person or
group who would otherwise be an Acquiring Person has become such  inadvertently,
and such person or group as promptly as practicable takes such actions as may be
necessary  so that  such  person  or group  would no  longer  be  considered  an
Acquiring Person.

         The Rights Agreement  provides that,  until the Distribution  Date, the
Rights  will be  transferred  with and only with the  Common  Shares.  Until the
Distribution  Date (or earlier  redemption  or  expiration  of the Rights),  new
Common Share  certificates  issued after the Record Date,  upon  transfer or new
issuance of Common  Shares,  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 Shares 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 Shares  represented  by such
certificate.  As soon as practicable  following the Distribution Date,  separate

<PAGE>

certificates  evidencing  the Rights  will be mailed to holders of record of the
Common  Shares as of the Close of  Business  on the  Distribution  Date and such
separate  certificates  alone will  evidence  the Rights.  If Common  Shares are
issued or sold  after the  Distribution  Date (but  prior to the  redemption  or
expiration  of the Rights) in  connection  with the exercise of stock options or
upon the  exercise,  conversion  or exchange of other  securities of the Company
outstanding  prior  to the  Distribution  Date,  the  Company  shall  issue  the
appropriate number of Rights in connection with such issuance or sale.

         The Rights are not exercisable until the Distribution  Date. The Rights
will expire on  September  14, 2008 (the "Final  Expiration  Date"),  unless the
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 Preferred Shares 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
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Shares at a price,  or
securities  convertible into Preferred Shares with a conversion price, less than
the  then  current  market  price of the  Preferred  Shares  or  (iii)  upon the
distribution to holders of the Preferred  Shares of evidences of indebtedness or
assets  (excluding  regular  periodic  cash  dividends  paid out of  earnings or
retained  earnings or dividends  payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

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

         Preferred  Shares  purchasable  upon exercise of the Rights will not be
redeemable.  Each  Preferred  Share will be  entitled  to a  quarterly  dividend
payment of 200 times the  dividend  declared per Common  Share.  In the event of
liquidation,  each Preferred Share will be entitled to a $2.00  preference,  and
thereafter the holders of the Preferred  Shares will be entitled to an aggregate
payment of 200 times the aggregate payment made per Common Share. Each Preferred
Share will have 200 votes,  voting together with the Common Shares.  Finally, in
the event of any merger,  consolidation  or other  transaction  in which  Common
Shares are exchanged, each Preferred Share will be entitled to receive 200 times
the amount  received per Common  Share.  These rights are protected by customary
antidilution provisions.

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

         In the event that any  person or group  becomes  an  Acquiring  Person,
unless the event causing the Designated  Percentage  threshold to be crossed and
the  person  or group  to  thereby  become  an  Acquiring  Person  is a  merger,
acquisition or other business combination described in

                                       2
<PAGE>

the next paragraph, each holder of a Right, other than Rights beneficially owned
by the Acquiring  Person (which will  thereafter be void),  will thereafter have
the right to receive upon  exercise that number of Common Shares having a market
value of two times the exercise  price of the Right on the terms and  conditions
set forth in the Rights  Agreement.  If the Company does not have authorized but
unissued  Common Shares  sufficient  to satisfy such  obligation to issue Common
Shares,  the Company is obligated to deliver upon payment of the exercise  price
of a Right an  amount  of cash or other  securities  equivalent  in value to the
Common Shares issuable upon exercise of a Right.

         In the event that any person or group  becomes an Acquiring  Person and
the  Company  merges  into or  engages  in certain  other  business  combination
transactions with an Acquiring Person, or 50% or more of its consolidated assets
or earning power are sold to an Acquiring Person,  each holder of a Right, other
than Rights  beneficially owned by an Acquiring Person, will thereafter have the
right to receive,  upon the exercise  thereof at the then current exercise price
of the Right,  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 Right.

         At any time after any person or group  becomes an Acquiring  Person and
prior  to the  acquisition  by  such  person  or  group  of 50% or  more  of the
outstanding  Common  Shares,  the Board of Directors of the Company may exchange
the Rights  (other than Rights owned by the  Acquiring  Person),  in whole or in
part,  at an  exchange  ratio of one Common  Share (or one  two-hundredths  of a
Preferred  Share, or of a share of a class or series of the Company's  preferred
stock having equivalent  rights,  preferences and privileges) 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  Preferred  Shares will be issued (other than
fractions  which are  integral  multiples  of one  two-hundredth  of a Preferred
Share,  which may, at the  election of the Company,  be evidenced by  depository
receipts) and in lieu  thereof,  an adjustment in cash will be made based on the
market price of the  Preferred  Shares on the last trading day prior to the date
of exercise.

         At any  time  prior  to such  time as a  person  or  group  becomes  an
Acquiring Person, the Board of Directors of the Company may redeem the Rights in
whole,  but not in  part,  at a  redemption  price  of  $0.001  per  Right.  The
redemption  of the Rights may be made  effective at such time, on such basis and
with  such  conditions  as the Board of  Directors  in its sole  discretion  may
establish.  After the period for redemption of the Rights has expired, the Board
may not amend the Rights  Agreement to extend the period for  redemption  of the
Rights. 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 terms of the Rights may be amended by a resolution  of the Board of
Directors without the consent of the holders of the Rights, except that from and
after such time as any  person or group  becomes an  Acquiring  Person,  no such
amendment may adversely affect the interests of the holders of the Rights (other
than an Acquiring Person).

                  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.

                  As of September 9, 1998, there were  approximately 9.2 million
of the Company's Common Shares outstanding. Each Common Share outstanding at the
close of business on September  21, 1998 will receive one Right.  As long as the
Rights are attached to the Common Shares,  one additional  Right shall be deemed
to be delivered  for each Common Share issued or  transferred  by the Company in
the future, including but not limited to Common Shares issuable upon exercise of
options  granted by the  Company.  Two  hundred  thousand  Preferred  Shares are
initially  reserved for issuance upon exercise of the Rights,  such number to be
subject to adjustment from time to time in accordance with the Rights Agreement.

                  The Rights Agreement,  which specifies the terms of the Rights
and which includes as exhibits  thereto the form of Certificate of  Designations
of Series A Junior Participating  Preferred Stock, the Form of Right Certificate
and the form of  Summary of Rights to  Purchase  Preferred  Shares,  is filed as
Exhibit 4.1 hereto. A copy of the Certificate of Designations of Series A Junior
Participating  Preferred  Stock as filed with the  Delaware  Secretary of State,
which  specifies  the terms of the  Preferred  Shares,  is filed as Exhibit  3.2
hereto. The aforementioned exhibits hereto are incorporated herein by reference,
and the foregoing description of the Rights and Preferred Shares is qualified in
its entirety by reference to such exhibits.

                         (Pursuant to Section 151 of the

                        Delaware General Corporation Law)

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

         Elantec Semiconductor, 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 September 9, 1998:

         RESOLVED,  that pursuant to the authority  granted to and vested in the
Board of  Directors  of this  Corporation  (hereinafter  called  the  "Board  of
Directors" or the "Board") in accordance  with the provisions of the Certificate
of  Incorporation  of the  Corporation,  the Board of Directors hereby creates a
series of Preferred Stock, par value $0.01 per share (the "Preferred Stock"), of
the  Corporation  and hereby states the  designation  and number of shares,  and
fixes the relative rights, preferences, and limitations thereof as follows:

         Series A Junior Participating Preferred Stock:

         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 200,000.  Such number of shares may be  increased or decreased by
resolution of the Board of Directors;  provided,  that no decrease  shall reduce
the  number  of shares of  Series A  Preferred  Stock to a number  less than the
number of shares  then  outstanding  plus the  number  of  shares  reserved  for
issuance upon the exercise of  outstanding  options,  rights or warrants or upon
the  conversion  of  any  outstanding   securities  issued  by  the  Corporation
convertible into Series A Preferred Stock.

         Section 2. Dividends and Distributions.

                  (A)  Subject to the rights of the holders of any shares of any
series of Preferred Stock (or any other stock) ranking prior and superior to the
Series A Preferred  Stock with  respect to  dividends,  the holders of shares of
Series A Preferred Stock shall be entitled to receive,  when, as and if declared
by the  Board of  Directors  out of funds  legally  available  for the  purpose,
quarterly  dividends payable in cash on the first 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

<PAGE>

Date  after the first  issuance  of a share or  fraction  of a share of Series A
Preferred  Stock, in an amount (if any) per share (rounded to the nearest cent),
subject to the  provision for  adjustment  hereinafter  set forth,  equal to 200
times the  aggregate per share amount of all cash  dividends,  and 200 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,  par
value $0.01 per share (the "Common  Stock"),  of the Company or a subdivision of
the  outstanding  shares of Common  Stock (by  reclassification  or  otherwise),
declared on the Common Stock since the immediately  preceding Quarterly Dividend
Payment  Date or, with respect to the first  Quarterly  Dividend  Payment  Date,
since  the  first  issuance  of any  share or  fraction  of a share of  Series A
Preferred  Stock. In the event the Corporation  shall at any time declare or pay
any dividend on the Common Stock payable in shares of Common Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the amount to which  holders  of shares of Series A  Preferred
Stock were entitled immediately prior to such event under the preceding sentence
shall be adjusted by  multiplying  such amount by a fraction,  the  numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

                  (B) The  Corporation  shall declare a dividend or distribution
on the 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).

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

         Section 3. Voting  Rights.  The holders of shares of Series A Preferred
Stock shall have the following voting rights:

                  (A) Subject to the provision for  adjustment  hereinafter  set
forth,  each share of Series A Preferred  Stock shall entitle the holder thereof
to 200  votes on all  matters  submitted  to a vote of the  stockholders  of the
Corporation.  In the event the Corporation  shall at any time declare or pay any
dividend  on the Common  Stock  payable in shares of Common  Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the  number of votes per share to which  holders  of shares of
Series A Preferred Stock were entitled  immediately prior to such event shall be
adjusted by multiplying such number by a fraction, the numerator of which is the
number of shares of Common 

                                       2
<PAGE>

Stock  outstanding  immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding  immediately prior to
such event.

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

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

         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 shares of Series A Preferred  Stock
outstanding shall have been paid in full, the Corporation shall not:

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

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

                           (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  (as  to  dividends  and  upon   dissolution,
liquidation or winding up) to the Series A Preferred Stock.

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

                                       3

         Section 6. Liquidation, Dissolution or Winding Up.

                  (A) Upon any  liquidation,  dissolution  or  winding up of the
Corporation, the holders of shares of Series A Preferred Stock shall be entitled
to receive,  prior and in  preference to any  distribution  of any assets of the
Corporation  to the holders of Common  Stock,  the amount of $2.00 per share for
each  share of  Series A  Preferred  Stock  then held by them.  Thereafter,  the
holders of shares of Series A  Preferred  Stock  shall be entitled to receive an
aggregate amount per share, subject to the provision for adjustment  hereinafter
set forth,  equal to 200 times the aggregate  amount to be distributed per share
to holders of shares of Common  Stock plus an amount  equal to any  accrued  and
unpaid dividends.  In the event the Corporation shall at any time declare or pay
any dividend on the Common Stock payable in shares of Common Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the  aggregate  amount to which  holders of shares of Series A
Preferred  Stock  were  entitled  immediately  prior  to such  event  under  the
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) If the assets of the  Corporation  legally  available  for
distribution  to the  holders  of  shares  of  Series  A  Preferred  Stock  upon
liquidation,  dissolution or winding up of the Corporation  are  insufficient to
pay the full  preferential  amount set forth in the first  sentence of paragraph
(A) above,  then the entire  assets of the  Corporation  legally  available  for
distribution  to the  holders of Series A Preferred  Stock shall be  distributed
among such holders in proportion to the shares of Series A Preferred  Stock then
held by them.

                  (C) The  foregoing  rights upon  liquidation,  dissolution  or
winding up provided to the holders of Series A Preferred  Stock shall be subject
to the rights of the  holders  of any other  series of  Preferred  Stock (or any
other stock)  ranking  prior and  superior to the Series A Preferred  Stock upon
liquidation, dissolution or winding up.

         Section 7.  Consolidation,  Merger,  etc. In case the Corporation shall
enter into any consolidation,  merger, combination or other transaction in which
the shares of Common  Stock are  exchanged  for or changed  into other  stock or
securities,  cash  and/or  other  property,  then in any such case each share of
Series A  Preferred  Stock  shall at the same  time be  similarly  exchanged  or
changed  into an amount  per  share,  subject to the  provision  for  adjustment
hereinafter  set  forth,  equal to 200  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 shares of Series A  Preferred  Stock shall be adjusted by
multiplying  such amount by a fraction,  the numerator of which is the number of
shares  of  Common  Stock  outstanding  immediately  after  such  event  and the
denominator  of  which is the  number  of  shares  of  Common  Stock  that  were
outstanding immediately prior to such event.

         Section 8. No Redemption.  The shares of Series A Preferred Stock shall
not be redeemable.

                                RIGHTS AGREEMENT


         Agreement,   dated  as  of   September   14,  1998,   between   Elantec
Semiconductor,  Inc.  Corporation,  a Delaware corporation (the "Company"),  and
ChaseMellon Shareholder Services, L.L.C. (the "Rights Agent").

         The Board of  Directors  of the Company has  authorized  and declared a
dividend of one preferred share purchase right (a "Right") for each Common Share
(as hereinafter defined) of the Company outstanding at the Close of Business (as
hereinafter  defined) on  September  21, 1998 (the  "Record  Date"),  each Right
representing  the right to purchase one  two-hundredth  of a Preferred Share (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  Common  Share that shall  become  outstanding  (i)  between the
Record Date and the earliest of the  Distribution  Date, the Redemption Date and
the Final  Expiration  Date (as such  terms  are  hereinafter  defined)  or (ii)
following  the  Distribution  Date  and  prior to the  Redemption  Date or Final
Expiration Date, pursuant to the exercise of stock options or under any employee
plan or  arrangement  or upon the  exercise,  conversion  or  exchange  of other
securities of the Company, which options or securities were outstanding prior to
the Distribution Date.

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

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

                  (a)  "Acquiring  Person"  shall  mean any Person who or which,
together  with  all  Affiliates  and  Associates  of such  Person,  shall be the
Beneficial  Owner of 20% (the  "Designated  Percentage")  or more of the  Common
Shares of the Company then  outstanding,  but shall not include (i) the Company,
(ii) any  Subsidiary  of the  Company,  (iii) any  employee  benefit plan of the
Company or any  Subsidiary  of the  Company or (iv) any  entity  holding  Common
Shares  for or  pursuant  to the  terms of any such  plan.  Notwithstanding  the
foregoing.

                           (A) No Person shall become an Acquiring Person if the
Board of  Directors  of the Company  determines  in good faith that a Person who
would otherwise be an Acquiring Person has become such  inadvertently,  and such
Person as promptly as practicable takes such actions as may be necessary so that
such Person would no longer be considered an Acquiring Person.

                           (B) No Person shall become an  "Acquiring  Person" as
the result of an acquisition of Common Shares by the Company which,  by reducing
the number of shares outstanding,  increases the proportionate  number of shares
beneficially owned by such Person and such Person's Affiliates and Associates to
the  Designated  Percentage  or more of the Common  Shares of the  Company  then
outstanding;  provided,  however, that if a Person,  together with such Person's
Affiliates and Associates,  shall become the Beneficial  Owner of the Designated
Percentage  or more of the Common  Shares of the  Company  then  outstanding  by
reason of share  purchases by the Company,  and such Person,  together  with its
Affiliates  and  Associates,  shall,

<PAGE>

after public  announcement  of such share  purchases by the Company,  become the
Beneficial  Owner of any  additional  Common  Shares of the  Company,  then such
Person shall be deemed to be an "Acquiring Person."

                  (b)  "Affiliate"  and  "Associate"  shall  have the  following
meanings:

                           (i) An "Affiliate" of, or a Person "affiliated" with,
a specified Person, is a Person that directly, or indirectly through one or more
intermediaries,  controls, or is controlled by, or is under common control with,
the  Person  specified.  For  this  purpose,   "control"  (including  the  terms
"controlling,"  "controlled  by" and  "under  common  control  with")  means the
possession, direct or indirect, of the power to direct or cause the direction of
the management and policies of a Person, whether through the ownership of voting
securities, by contract or otherwise;

                           (ii)  The  term   "Associate"   used  to  indicate  a
relationship  with any Person  shall mean (A) any  corporation  or  organization
(other than the Company or a majority-owned  subsidiary of the Company) of which
such  Person is an  officer  or  partner  or is,  directly  or  indirectly,  the
Beneficial Owner of 10% or more of any class of equity securities, (B) any trust
or other estate in which such Person has a substantial beneficial interest or as
to which such Person serves as trustee or in a similar fiduciary  capacity,  and
(C) any relative or spouse of such Person,  or any relative of such spouse,  who
has the same home as such  Person or who is a director or officer of the Company
or any of its parents or Subsidiaries.

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

                           (i) which such Person owns, directly or indirectly;

                           (ii) which  such  Person has (A) the right to acquire
(whether  such right is  exercisable  immediately  or only after the  passage of
time)  pursuant  to any  agreement,  arrangement  or  understanding  (other than
customary  agreements  with and between  underwriters  and selling group members
with  respect  to a  bona  fide  public  offering  of  securities),  written  or
otherwise,  or upon the exercise of conversion rights,  exchange rights,  rights
(other than the Rights), warrants or options, or otherwise;  provided,  however,
that a  Person  shall  not  be  deemed  to be the  Beneficial  Owner  of,  or to
beneficially  own,  securities  tendered  pursuant to a tender or exchange offer
made by or on behalf of such Person until such tendered  securities are accepted
for purchase or exchange;  or (B) the right to vote  pursuant to any  agreement,
arrangement  or  understanding;  provided,  however,  that a Person shall not be
deemed the  Beneficial  Owner of, or to  beneficially  own,  any security if the
agreement,  arrangement or understanding to vote such security (1) arises solely
from a revocable  proxy or consent  given to such Person in response to a public
proxy or consent  solicitation  made  pursuant to, and in accordance  with,  the
applicable rules and regulations  promulgated  under the Exchange Act and (2) is
not also  then  reportable  on  Schedule  13D  under  the  Exchange  Act (or any
comparable or successor report); or

                           (iii)  which  are  beneficially  owned,  directly  or
indirectly,  by any other  Person  with  which such  Person  has any  agreement,
arrangement or understanding  (other than customary  agreements with and between
underwriters  and  selling  group  members  with  respect to a bona fide  public
offering of  securities),  written or  otherwise,  for the purpose of acquiring,

                                       2
<PAGE>

holding,  voting  (except to the extent  contemplated  by the proviso to Section
1(c)(ii)(B)) or disposing of any securities of the Company.

                           Notwithstanding   anything  in  this   definition  of
Beneficial  Ownership to the contrary,  the phrase "then outstanding," when used
with reference to a Person's Beneficial  Ownership of securities of the Company,
shall mean the number of such securities  then issued and  outstanding  together
with the number of such  securities  not then  actually  issued and  outstanding
which such Person would be deemed to own beneficially hereunder.

                  (d) "Business Day" shall mean any day other than a Saturday, a
Sunday,  or a day on which banking  institutions  in the State of California are
authorized or obligated by law or executive order to close.

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

                  (f) "Common  Shares"  when used with  reference to the Company
shall  mean the  shares  of common  stock,  par value  $0.01 per  share,  of the
Company.  "Common  Shares" when used with reference to any Person other than the
Company  shall mean the capital  stock (or equity  interest)  with the  greatest
voting power of such other  Person or, if such other  Person is a Subsidiary  of
another   Person,   the  Person  or  Persons  which   ultimately   control  such
first-mentioned Person.

                  (g) "Designated  Percentage"  shall have the meaning set forth
in Section 1(a) hereof.

                  (h)  "Distribution  Date"  shall have the meaning set forth in
Section 3 hereof.

                  (i) "Exchange Act" shall mean the  Securities  Exchange Act of
1934, as amended.

                  (j) "Final  Expiration  Date" shall have the meaning set forth

Section 7(b) hereof.

                  (m)  "Preferred  Shares"  shall mean shares of Series A Junior

the rights and preferences set forth in the Certificate of Designations attached
to this Agreement as Exhibit A.

                  (n)  "Redemption  Date"  shall have the  meaning  set forth in
Section 7(a) hereof.

                  (o)  "Shares  Acquisition  Date" shall mean the earlier of the
date of (i) the public  announcement by the Company or an Acquiring  Person that
an Acquiring  Person has become such or (ii) the public  disclosure  of facts by
the Company or an  Acquiring  Person  indicating  that an  Acquiring  Person has
become such.

                  (p)  "Subsidiary" of any Person shall mean any Person of which
a  majority  of the  voting  power of the  voting  equity  securities  or equity
interest is owned, directly or indirectly, by such Person.

                  (q)  A   "Successor"   shall   mean   the   estate   or  legal
representative  of  a  deceased  individual,   the  beneficiary  of  a  deceased

         Section 2. Appointment of Rights Agent. The Company hereby appoints the
Rights  Agent to act as agent for the Company in  accordance  with the terms and
conditions  hereof,  and the Rights Agent hereby accepts such  appointment.  The
Company  may from  time to time  appoint  such  co-Rights  Agents as it may deem
necessary or desirable.

         Section 3.  Issue of Right Certificates.

                  (a) Until the  earlier  of (i) the tenth day after the  Shares
Acquisition  Date or (ii) the tenth  Business  Day (or such later date as may be
determined by action of the Board of Directors of the Company prior to such time
as any Person becomes an Acquiring  Person) after 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 Common Shares for or pursuant to the terms of any
such plan) to  commence a tender or  exchange  offer the  consummation  of which
would result in any such Person becoming an Acquiring Person (including any such
date which is after the date of this  Agreement and prior to the issuance of the
Rights;  the earlier of such dates being herein referred to as the "Distribution
Date");  (x) the Rights will be evidenced  (subject to the provisions of Section
3(b) hereof) by the  certificates  for Common Shares  registered in the names of
the  holders  thereof  (which  certificates  shall  also be  deemed  to be Right
Certificates)  and not by  separate  Right  Certificates,  and (y) the  right to
receive Right  Certificates  will be  transferable  only in connection  with the
transfer of Common Shares. As soon as practicable  after the Distribution  Date,
the Company will prepare and execute, the Rights Agent will countersign, and the
Company will send or cause to be sent (and the Rights Agent will,  if requested,
send) by first-class,  insured,  postage-prepaid  mail, to each record holder of
Common  Shares as of the Close of  Business  on the  Distribution  Date,  at the
address of such holder shown on the records of the Company, a Right Certificate,
in  substantially  the  form  of  Exhibit  B  hereto  (a  "Right  Certificate"),
evidencing one Right for each Common Share so held. As of the Distribution Date,
the Rights will be evidenced solely by such Right Certificates.

                  (b) On the Record Date, or as soon as practicable  thereafter,
the  Company  will send a copy of a Summary  of  Rights  to  Purchase  Preferred
Shares, in substantially the form of Exhibit C hereto (the "Summary of Rights"),
by first-class,  postage-prepaid mail, to each record holder of Common Shares as
of the Close of Business on the Record Date, at the address of such holder shown
on the records of the Company.  With respect to  certificates  for Common Shares
outstanding as of the Record Date, until the Distribution  Date, the Rights will
be evidenced by

                                       4
<PAGE>

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

                  (c)  Certificates  for Common Shares which become  outstanding
(including, without limitation, reacquired Common Shares referred to in the last
sentence of this  paragraph (c)) after the Record Date but prior to the earliest
of the Distribution Date, the Redemption Date or the Final 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  (the  "Rights")  as set  forth  in a Rights
                Agreement  between Elantec  Semiconductor,  Inc. and ChaseMellon
                Shareholder Services, L.L.C., dated as of September 14, 1998, as
                such may subsequently be amended (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
                Elantec Semiconductor,  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. Elantec Semiconductor, Inc. will mail to the holder
                of this  certificate  a copy  of the  Rights  Agreement  without
                charge after receipt of a written request therefor. As described
                in   Section   11(a)(ii)   of  the  Rights   Agreement,   Rights
                beneficially owned by any Person who becomes an Acquiring Person
                (as defined in the Rights  Agreement)  and certain other Persons
                shall become null and void.

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

         Section 4. Form of Right Certificates.  The Right Certificates (and the
forms of election to purchase  Preferred  Shares and of assignment to be printed
on the reverse thereof) shall be substantially  the same as Exhibit B hereto and
may have such marks of identification or designation and such legends, summaries
or endorsements  printed thereon as the Company may deem  appropriate and as are
not inconsistent with the provisions of this Agreement, or as may be required to
comply with any  applicable  law or with any rule or  regulation  made  pursuant
thereto or with any rule or regulation of any stock exchange on which the Rights
may from time to time be listed,  or to  conform to usage.  Subject to the other
provisions of this Agreement,  the Right  Certificates shall entitle the holders
thereof to purchase  such number of one  two-hundredth  of a Preferred  Share as
shall be set forth  therein at the  Purchase  Price,  but the number of such one
two-hundredths  of a Preferred  Share and the Purchase Price shall be subject to
adjustment as provided herein.

                                       5
<PAGE>

         Section 5.  Countersignature  and Registration.  The Right Certificates
shall be  executed on behalf of the  Company by its  Chairman of the Board,  its
Chief  Executive  Officer,  its President,  any of its Vice  Presidents,  or its
Treasurer, 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 any  Assistant  Secretary of the  Company,  either  manually or by
facsimile signature.  The Right Certificates shall be manually  countersigned by
the Rights Agent  (unless  applicable  exchange  rules and law permit  facsimile
signature,  in which case the Rights Agent  signature may be by  facsimile)  and
shall not be valid for any purpose unless countersigned.  In case any officer of
the Company who shall have signed any of the Right  Certificates  shall cease to
be such officer of the Company before  countersignature  by the Rights Agent and
issuance and delivery by the Company, such Right Certificates, nevertheless, may
be  countersigned  by the Rights  Agent and issued and  delivered by the Company
with the same  force and  effect as though  the  person  who  signed  such Right
Certificates  had not ceased to be such  officer of the  Company;  and any Right
Certificate  may be signed on behalf of the  Company by any person  who,  at the
actual  date of the  execution  of such  Right  Certificate,  shall  be a proper
officer of the Company to sign such Right  Certificate,  although at the date of
the execution of this Rights Agreement any such person was not such an officer.

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

         Section  6.  Transfer,  Split Up,  Combination  and  Exchange  of Right
Certificates;  Mutilated, Destroyed, Lost or Stolen Right Certificates.  Subject
to the provisions of Section 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
earlier  of the  Redemption  Date  or  the  Final  Expiration  Date,  any  Right
Certificate or Right Certificates  (other than Right  Certificates  representing
Rights that have become void pursuant to Section  11(a)(ii)  hereof or that have
been  exchanged  pursuant  to Section 24 hereof) may be  transferred,  split up,
combined or  exchanged  for another  Right  Certificate  or Right  Certificates,
entitling the registered holder to purchase a like number of one  two-hundredths
of a Preferred Share as the Right Certificate or Right Certificates  surrendered
then  entitled  such  holder to  purchase.  Any  registered  holder  desiring to
transfer,  split  up,  combine  or  exchange  any  Right  Certificate  or  Right
Certificates  shall make such request in writing  delivered to the Rights Agent,
and  shall  surrender  the  Right  Certificate  or  Right   Certificates  to  be
transferred,  split up,  combined or  exchanged at the  principal  office of the
Rights  Agent.  Thereupon  the Company  shall execute and the Rights Agent shall
countersign  and deliver to the person entitled  thereto a Right  Certificate or
Right Certificates, as the case may be, as so requested. The Company may require
payment  of a sum  sufficient  for any tax or  governmental  charge  that may be
imposed in connection  with any transfer,  split up,  combination or exchange of
Right Certificates.

         Upon receipt by the Company and the Rights Agent of evidence reasonably
satisfactory  to them of the loss,  theft,  destruction or mutilation of a Right
Certificate,  and,  in case of  loss,  theft or  destruction,  of  indemnity  or
security  reasonably  satisfactory  to  them,  and,  at the  Company's  request,
reimbursement  to the Company and the Rights  Agent of all  reasonable  

                                       6
<PAGE>

expenses  incidental  thereto,  and  upon  surrender  to the  Rights  Agent  and
cancellation  of the Right  Certificate if mutilated,  the Company will make and
deliver a new Right  Certificate  of like tenor to the Rights Agent for delivery
to the  registered  holder in lieu of the  Right  Certificate  so lost,  stolen,
destroyed or mutilated.

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

                  (a)  The  registered  holder  of  any  Right  Certificate  may
exercise the Rights evidenced  thereby (except as otherwise  provided herein) in
whole or in part at any time after the  Distribution  Date upon surrender of the
Right  Certificate,  with the form of election  to purchase on the reverse  side
thereof duly executed, to the Rights Agent at the principal office of the Rights
Agent, together with payment of the Purchase Price for each one two-hundredth of
a  Preferred  Share as to which the  Rights  are  exercised,  at or prior to the
earliest  of (i) the  Close of  Business  on  September  14,  2008  (the  "Final
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
Section  23 hereof  (the  "Redemption  Date"),  or (iii) the time at which  such
Rights are exchanged as provided in Section 24 hereof.

                  (b)  The  purchase  price  for  each  one  two-hundredth  of a
Preferred Share pursuant to the exercise of a Right (the "Purchase Price") shall
initially  be  $25.00,  shall be  subject  to  adjustment  from  time to time as
provided in  Sections  11 and 13 hereof and shall be payable in lawful  money of
the United States of America in accordance with paragraph (c) below.

                  (c)  Upon   receipt  of  a  Right   Certificate   representing
exercisable  Rights,  with the form of election to purchase and certificate duly
executed,  accompanied  by  payment of the  Purchase  Price for the shares to be
purchased and an amount equal to any applicable transfer tax required to be paid
by the holder of such Right  Certificate in accordance  with Section 9 hereof by
certified  check,  cashier's  check or money  order  payable to the order of the
Company,  the Rights Agent shall thereupon promptly (i) (A) requisition from any
transfer  agent of the  Preferred  Shares  certificates  for the  number  of one
two-hundredths  of a Preferred  Share to be  purchased  and the  Company  hereby
irrevocably  authorizes its transfer agent to comply with all such requests,  or
(B) requisition from any depositary  agent for the Preferred  Shares  depositary
receipts  representing such number of one two-hundredths of a Preferred Share as
are to be  purchased  (in  which  case  certificates  for the  Preferred  Shares
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  Preferred Shares in
accordance with Section 14 hereof,  (iii) after receipt of such  certificates or
depositary receipts,  cause the same to be delivered to or upon the order of the
registered holder of such Right Certificate, registered in such name or names as
may be  designated  by such  holder and (iv) when  appropriate,  after  receipt,
deliver  such cash to or upon the order of the  registered  holder of such Right
Certificate.

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

                                       7
<PAGE>

                  (e) The Company  covenants and agrees that it will cause to be
reserved and kept available, out of its authorized and unissued Preferred Shares
or any  Preferred  Shares held in its treasury,  the number of Preferred  Shares
that will be sufficient to permit the exercise in full of all outstanding Rights
in accordance with this Section 7.

                  (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 following the form of
election to  purchase  set forth on the  reverse  side of the Right  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 Right  Certificates.  All
Right Certificates surrendered for the purpose of exercise,  transfer, split up,
combination  or exchange  shall,  if surrendered to the Company or to any of its
agents,  be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered  to the Rights Agent,  shall be cancelled by it, and no Right
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
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  Right  Certificate  purchased  or acquired by the
Company otherwise than upon the exercise thereof. The Rights Agent shall deliver
all  cancelled  Right  Certificates  to the  Company,  or shall,  at the written
request of the Company,  destroy such cancelled Right Certificates,  and in such
case shall deliver a certificate of destruction thereof to the Company.

         Section 9. Status and  Availability  of Preferred  Shares.  The Company
covenants  and agrees that it will take all such action as may be  necessary  to
ensure that all Preferred Shares delivered upon exercise of Rights shall, at the
time of delivery  of the  certificates  for such  Preferred  Shares  (subject to
payment of the Purchase  Price),  be duly and validly  authorized and issued and
fully paid and non-assessable shares.

         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 Right  Certificates  or of
any  Preferred  Shares  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 Right  Certificates  to a person other than,  or the
issuance or delivery of  certificates  or depositary  receipts for the Preferred
Shares  in a name  other  than  that of,  the  registered  holder  of the  Right
Certificate evidencing Rights surrendered for exercise or to issue or to deliver
any  certificates or depositary  receipts for Preferred Shares upon the exercise
of any  Rights  until  any such tax  shall  have  been  paid (any such tax being
payable by the holder of such Right  Certificate  at the time of  surrender)  or
until it has been established to the Company's  reasonable  satisfaction that no
such tax is due.

         Section 10. Preferred Shares Record Date. Each person in whose name any
certificate for Preferred Shares is issued upon the exercise of Rights shall for
all  purposes  be deemed to have  become the  holder of record of the  Preferred
Shares  represented  thereby on, and such  certificate  shall be dated, the date
upon which the Right Certificate evidencing such Rights was

                                       8
<PAGE>

duly surrendered and payment of the Purchase Price (and any applicable  transfer
taxes) was made.  Prior to the  exercise of the Rights  evidenced  thereby,  the
holder of a Right Certificate shall not be entitled to any rights of a holder of
Preferred Shares 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 of Preferred Shares covered by each Right
and the number of Rights outstanding are subject to adjustment from time to time
as provided in this Section 11.

                       (a) (i) In the event the Company  shall at any time after
the date of this  Agreement  (A)  declare a  dividend  on the  Preferred  Shares
payable in Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C)
combine the  outstanding  Preferred  Shares into a smaller  number of  Preferred
Shares or (D) issue any shares of its capital stock in a reclassification of the
Preferred  Shares  (including  any such  reclassification  in connection  with a
consolidation  or merger in which the  Company is the  continuing  or  surviving
corporation),  except as otherwise  provided in this Section 11(a), the Purchase
Price in  effect  at the time of the  record  date for such  dividend  or of the
effective date of such  subdivision,  combination or  reclassification,  and the
number  and kind of shares of capital  stock  issuable  on such  date,  shall be
proportionately  adjusted so that the holder of any Right  exercised  after such
time shall be  entitled to receive  the  aggregate  number and kind of shares of
capital stock which, if such Right had been exercised  immediately prior to such
date,  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.

                           (ii)   Subject   to  the  last   paragraph   of  this
subparagraph  (ii) and to  Section 24 of this  Agreement,  in the event that any
Person shall become an Acquiring Person, unless the event causing the Designated
Percentage threshold to be crossed and the Person to thereby become an Acquiring
Person is a transaction  set forth in Section 13 hereof,  each holder of a Right
shall thereafter have a right to receive, upon exercise thereof at a price equal
to  the  then  current   Purchase   Price   multiplied  by  the  number  of  one
two-hundredths  of a Preferred Share for which a Right is then  exercisable,  in
accordance  with the terms of this  Agreement  and in lieu of Preferred  Shares,
such number of Common  Shares of the Company as shall equal the result  obtained
by (x)  multiplying  the  then  current  Purchase  Price  by the  number  of one
two-hundredths  of a Preferred  Share for which a Right is then  exercisable and
dividing  that  product by (y) 50% of the then current per share market price of
the Company's Common Shares (determined pursuant to Section 11(d) hereof) on the
date such Person became an Acquiring Person.

                                From and  after  the  occurrence  of any  Person
becoming  an  Acquiring  Person,  any  Rights  that  are  or  were  acquired  or
beneficially  owned by such  Acquiring  Person (or any Associate or Affiliate of
such  Acquiring  Person)  shall  be void and any  holder  of such  Rights  shall
thereafter  have no right to exercise  such Rights  under any  provision of this
Agreement.  No Right  Certificate  shall be issued  pursuant  to  Section 3 that
represents Rights  beneficially  owned by an Acquiring Person whose Rights would
be void  pursuant  to the  preceding  sentence  or any  Associate  or  Affiliate
thereof;  no Right  Certificate shall be issued at 

                                       9
<PAGE>

any time upon the  transfer of any Rights to an  Acquiring  Person  whose Rights
would be void pursuant to the  preceding  sentence or any Associate or Affiliate
thereof or to any nominee of such Acquiring Person,  Associate or Affiliate; and
any Right Certificate delivered to the Rights Agent for transfer to an Acquiring
Person  whose  Rights would be void  pursuant to the  preceding  sentence or any
Associate or Affiliate  thereof shall be cancelled.  This paragraph  shall apply
not only to an initial Acquiring Person, and its Affiliates and Associates,  but
also to subsequent Acquiring Persons, and their Affiliates and Associates.

                           (iii) In the event that the  number of Common  Shares
which are  authorized  by the Company's  certificate  of  incorporation  and not
outstanding or subscribed  for, or reserved or otherwise  committed for issuance
for purposes other than upon exercise of the Rights, is not sufficient to permit
the holder of each Right to purchase  the number of Common  Shares to which such
holder would be entitled  upon the exercise in full of the Rights in  accordance
with the  foregoing  subparagraph  (ii) of paragraph (a) of this Section 11, the
Company  shall:  (A)  determine the excess of (1) the value of the Common Shares
issuable  upon the  exercise  of a Right  (calculated  as  provided  in the last
sentence of this  subparagraph  (iii)) pursuant to Section 11(a)(ii) hereof (the
"Current  Value") over (2) the Purchase Price (such excess,  the "Spread"),  and
(B) with respect to each Right,  make adequate  provision to substitute for such
Common Shares,  upon payment of the applicable  Purchase Price,  (1) cash, (2) a
reduction in the Purchase Price, (3) Common Shares or other equity securities of
the Company  (including,  without  limitation,  shares,  or units of shares,  of
preferred  stock which the Board of Directors of the Company has  determined  to
have the same value as shares of common stock (such equity  securities,  "common
stock  equivalents")),  (4) debt securities of the Company, (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 in good faith; provided,  however, if the Company shall
not have made adequate  provision to deliver value  pursuant to clause (B) above
within thirty (30) days  following  the later of (x) the first  occurrence of an
event  triggering  the rights to purchase  Common  Shares  described  in Section
11(a)(ii) and (y) the date on which the Company's  right of redemption  pursuant
to Section 23(a)  expires (the later of (x) and (y) being  referred to herein as
the "Section  11(a)(ii)  Trigger Date"),  then the Company shall be obligated to
deliver, upon the surrender for exercise of a Right without requiring payment of
the Purchase Price,  shares of common stock (to the extent  available) and then,
if necessary,  cash,  which shares and cash have an aggregate value equal to the
Spread.  If the Board of Directors of the Company shall  determine in good faith
that it is likely that  sufficient  additional  shares of common  stock could be
authorized for issuance upon exercise in full of the Rights, the thirty (30) day
period set forth  above may be extended  to the extent  necessary,  but not more
than ninety (90) days after the Section  11(a)(ii)  Trigger  Date, in order that
the  Company  may  seek  stockholder  approval  for  the  authorization  of such
additional  shares  (such  period,  as it may  be  extended,  the  "Substitution
Period").  To the extent  that the Company  determines  that some action need be
taken pursuant to the first and/or second sentences of this Section  11(a)(iii),
the Company (x) shall provide,  subject to Section 7(f) hereof, that such action
shall  apply  uniformly  to all  outstanding  Rights,  and (y) may  suspend  the
exercisability of the Rights until the expiration of the Substitution  Period in
order to seek any  authorization  of  additional  shares  and/or to  decide  the
appropriate  form of distribution to be made pursuant to such first sentence and
to determine the value thereof. In the event of any such suspension, the Company
shall  make a public  announcement,  and shall  deliver  to the  Rights  Agent a
statement,  stating that the  exercisability  of the Rights has been temporarily
suspended.  At such time as the  suspension is no longer in effect,  the Company
shall make  another  public  announcement,  and 

                                       10
<PAGE>

deliver to the Rights  Agent a  statement,  so  stating.  For  purposes  of this
Section  11(a)(iii),  the value of the Common  Shares  shall be the  current per
share market price (as determined  pursuant to Section  11(d)(i)  hereof) of the
Common Shares on the Section 11(a)(ii) Trigger Date and the value of any "common
stock equivalent" shall be deemed to have the same value as the Common Shares on
such date.

                  (b) In case  the  Company  shall  fix a  record  date  for the
issuance  of rights,  options or warrants  to all  holders of  Preferred  Shares
entitling them to subscribe for or purchase  Preferred  Shares (or shares having
the same rights, privileges and preferences as the Preferred Shares ("equivalent
preferred   shares"))  or  securities   convertible  into  Preferred  Shares  or
equivalent  preferred  shares  at a price  per  Preferred  Share  or  equivalent
preferred  share  (or  having  a  conversion  price  per  share,  if a  security
convertible into Preferred Shares or equivalent  preferred shares) less than the
then  current  per share  market  price of the  Preferred  Shares (as defined in
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 Preferred Shares outstanding on such record date plus the
number of  Preferred  Shares  which the  aggregate  offering  price of the total
number of Preferred Shares and/or  equivalent  preferred shares so to be offered
(and/or the aggregate initial conversion price of the convertible  securities so
to be offered) would  purchase at such current market price and the  denominator
of which shall be the number of Preferred Shares outstanding on such record date
plus the number of  additional  Preferred  Shares  and/or  equivalent  preferred
shares to be offered for subscription or purchase (or into which the convertible
securities so to be offered are initially convertible);  provided, however, that
in no event shall the consideration to be paid upon the exercise of one Right be
less than the  aggregate par value of the shares of capital stock of the Company
issuable upon exercise of one Right. In case such subscription price may be paid
in a consideration  part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith by the Board of
Directors of the Company,  whose determination shall be described in a statement
filed with the Rights Agent.  Preferred  Shares owned by or held for the account
of the  Company  shall not be deemed  outstanding  for the  purpose  of any such
computation.  Such adjustment shall be made successively  whenever such a record
date is fixed; and in the event that such rights, options or warrants are not so
issued,  the  Purchase  Price shall be adjusted to be the  Purchase  Price which
would then be in effect if such record date had not been fixed.

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

                                       11
<PAGE>

Right be less than the aggregate par value of the shares of capital stock of the
Company to be issued upon exercise of one Right.  Such adjustments shall be made
successively  whenever  such a record date is fixed;  and in the event that such
distribution  is not so made,  the Purchase  Price shall again be adjusted to be
the  Purchase  Price  which  would then be in effect if such record date had not
been fixed.

                       (d) (i) For the purpose of any computation hereunder, the
"current per share market price" of any security (a  "Security"  for the purpose
of this  Section  11(d)(i)) on any date shall be deemed to be the average of the
daily closing prices per share of such Security for the 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 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 New York Stock  Exchange or,
if the  Security  is not  listed or  admitted  to  trading on the New York Stock
Exchange, as reported in the principal consolidated transaction reporting system
with respect to securities listed on the principal national  securities exchange
on which the  Security is listed or  admitted to trading or, if the  Security is
not listed or admitted to trading on any national securities exchange,  the last
quoted  price,  or, if not so quoted,  the average of the high bid and low asked
prices in the  over-the-counter  market, as reported by The Nasdaq Stock Market,
Inc.  ("Nasdaq")  or such other  system then in use, or, if on any such date the
Security is not quoted by any such organization,  the average of the closing bid
and asked prices as furnished by a professional  market maker making a market in
the  Security  selected  by the  Board of  Directors  of the  Company.  The term
"Trading  Day"  shall  mean a day on which  the  principal  national  securities
exchange on which the  Security is listed or admitted to trading is open for the
transaction of business or, if the Security is not listed or admitted to trading
on any national securities exchange, a Business Day.

                           (ii) For the  purpose of any  computation  hereunder,
the "current per share market price" of the Preferred Shares shall be determined
in accordance  with the method set forth in Section  11(d)(i).  If the Preferred
Shares are not publicly  traded,  the  "current  per share market  price" of the
Preferred Shares shall be conclusively deemed to be the current per share market
price  of  the  Common  Shares  as  determined   pursuant  to  Section  11(d)(i)
(appropriately  adjusted to reflect any stock split,  stock  dividend or similar
transaction  occurring  after the date hereof),  multiplied  by one hundred.  If
neither  the Common  Shares nor the  Preferred  Shares are  publicly  held or so
listed or traded, "current per share market price" shall mean the fair value per
share as  determined  in good faith by the Board of  Directors  of the  Company,
whose  determination  shall be  described  in a statement  filed with the Rights
Agent.

                  (e) No  adjustment  in the  Purchase  Price  shall be required
unless such  adjustment  would require an increase or decrease of at least 1% in
the Purchase Price;  provided,  

                                       12
<PAGE>

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-millionth of a Preferred Share or one
one-thousandth   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 three  years from the
date of the transaction which requires such adjustment.

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

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

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

                  (i)  The  Company  may  elect  on or  after  the  date  of any
adjustment of the Purchase Price to adjust the number of Rights in  substitution
for any  adjustment  in the number of one  two-hundredths  of a Preferred  Share
purchasable upon the exercise of a Right.  Each of the Rights  outstanding after
such  adjustment of the number of Rights shall be exercisable  for the number of
one  two-hundredths  of a  Preferred  Share for  which a Right  was  exercisable
immediately  prior to such  adjustment.  Each Right held of record prior to such
adjustment  of  the  number  of  Rights  shall  become  that  number  of  Rights
(calculated to the nearest one 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 Right
Certificates  have been  distributed,  shall be at least 10 days  later than the
date of the public  announcement.  If Right  Certificates have been distributed,
upon each adjustment of the number of Rights pursuant to this Section 11(i), the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Right Certificates on such 

                                       13
<PAGE>

record date Right  Certificates  evidencing,  subject to Section 14 hereof,  the
additional  Rights to which such  holders  shall be entitled as a result of such
adjustment,  or, at the option of the Company,  shall cause to be distributed to
such  holders  of  record  in   substitution   and  replacement  for  the  Right
Certificates  held by such  holders  prior to the date of  adjustment,  and upon
surrender thereof, if required by the Company, new Right Certificates evidencing
all the Rights to which such holders  shall be entitled  after such  adjustment.
Right  Certificates  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 Right  Certificates  on the  record  date
specified in the public announcement.

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

                  (k) Before  taking any action that would  cause an  adjustment
reducing the Purchase Price below one two-hundredth of the then par value of the
Preferred  Shares  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
non-assessable Preferred Shares at such adjusted Purchase Price.

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

                  (m)   Anything   in   this   Section   11  to   the   contrary
notwithstanding,  the Company  shall be entitled to make such  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  Shares,  (ii)  issuance  wholly  for  cash  of  Preferred  Shares  or
securities  which  by their  terms  are  convertible  into or  exchangeable  for
Preferred  Shares,  (iii)  dividends  on Preferred  Shares  payable in Preferred
Shares  or  (iv)  issuance  of any  rights,  options  or  warrants  referred  to
hereinabove  in Section  11(b),  hereafter made by the Company to holders of its
Preferred Shares shall not be taxable to such stockholders.

                  (n) 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 the Common Shares  payable in Common Shares or (ii) effect a
subdivision,   combination   or   consolidation   of  the   Common   Shares  (by
reclassification  or  otherwise  other than by payment  of  dividends  in Common
Shares) into a greater or lesser number of Common Shares,  then in any such case
(i) the number of one two-hundredths of a Preferred Share purchasable after such
event upon proper 

                                       14
<PAGE>

exercise  of each Right shall be  determined  by  multiplying  the number of one
two-hundredths  of a Preferred  Share so purchasable  immediately  prior to such
event by a  fraction,  the  numerator  of which is the  number of Common  Shares
outstanding  immediately  before such event and the  denominator of which is the
number of Common Shares outstanding  immediately after such event, and (ii) each
Common  Share  outstanding  immediately  after such event shall have issued with
respect  to it that  number  of  Rights  which  each  Common  Share  outstanding
immediately  prior to such event had issued with respect to it. The  adjustments
provided for in this Section  11(n) shall be made  successively  whenever such a
dividend is declared or paid or such a subdivision, combination or consolidation
is effected.

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

         Section 12. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an  adjustment  is made as  provided in 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  Common  Shares or the
Preferred Shares a copy of such certificate and (c) mail a brief summary thereof
to each holder of a Right Certificate in accordance with Section 25 hereof.

         Section  13.  Consolidation,  Merger or Sale or  Transfer  of Assets or
Earning  Power.  In the event that any Person shall become an Acquiring  Person,
and,  directly or indirectly,  (a) the Company shall  consolidate with, or merge
with and into, an Acquiring Person, or an Affiliate or Associate of an Acquiring
Person,  (b) an  Acquiring  Person or an  Affiliate or Associate of an Acquiring
Person,  shall consolidate with the Company,  or merge with and into the Company
and the Company shall be the continuing or surviving  corporation of such merger
and, in connection  with such merger,  all or part of the Common Shares shall be
changed into or exchanged for stock or other  securities of any other Person (or
the  Company) or cash or any other  property,  or (c) the Company  shall sell or
otherwise  transfer (or one or more of its Subsidiaries  shall sell or otherwise
transfer), in one or more transactions,  assets or earning power aggregating 50%
or more of the  assets or  earning  power of the  Company  and its  Subsidiaries
(taken as a whole) to an  Acquiring  Person,  or an Affiliate or Associate of an
Acquiring Person, then, and in each such case, proper provision shall be made so
that (i) each holder of a Right  (except as  otherwise  provided  herein)  shall
thereafter have the right to receive, upon the exercise thereof at a price equal
to  the  then  current   Purchase   Price   multiplied  by  the  number  of  one
two-hundredths  of a Preferred Share for which a Right is then  exercisable,  in
accordance  with the terms of this  Agreement  and in lieu of Preferred  Shares,
such number of Common  Shares of the Person in the  transaction  (including  the
Company as successor thereto or as the surviving corporation) who is issuing the
consideration  with  the  greatest  fair  market  value to the  Company  and its
stockholders in connection  with such  transaction  (the "Principal  Issuer") as
shall equal the result  obtained by (A)  multiplying  the then current  Purchase
Price by the number of one two-hundredths of a Preferred Share for which a Right
is then exercisable and dividing that product by (B) 50% of the then current per
share  market price of the Common  Shares of the  Principal  Issuer  (determined
pursuant  to  Section  11(d)  hereof)  on  the  date  of  consummation  of  such
consolidation,  merger,  sale or  transfer;  (ii)  the  Principal  Issuer  shall
thereafter  be liable for, and shall  assume,  by virtue

                                       15
<PAGE>

of such consolidation,  merger, sale or transfer, all the obligations and duties
of the  Company  pursuant  to this  Agreement;  (iii) the term  "Company"  shall
thereafter  be deemed to refer to the Principal  Issuer;  and (iv) the Principal
Issuer shall take such steps (including,  but not limited to, the reservation of
a sufficient number of its Common Shares in accordance with Section 9 hereof) in
connection  with  such  consummation  as may be  necessary  to  assure  that the
provisions  hereof shall  thereafter be applicable,  as nearly as reasonably may
be, in relation to the Common Shares thereafter deliverable upon the exercise of
the Rights.  The Company  covenants and agrees that it shall not  consummate any
such  consolidation,  merger,  sale or transfer unless prior thereto the Company
and the Principal Issuer shall have executed and delivered to the Rights Agent a
supplemental  agreement  so  providing.  The  Company  shall not enter  into any
transaction  of the kind  referred to in this  Section 13 if at the time of such
transaction   there  are  any  rights,   warrants,   instruments  or  securities
outstanding  or  any  agreements  or  arrangements  which,  as a  result  of the
consummation of such transaction,  would eliminate or substantially diminish the
benefits  intended to be afforded by the Rights.  The provisions of this Section
13 shall similarly  apply to successive  mergers or  consolidations  or sales or
other transfers.

         Section 14.  Fractional Rights and Fractional Shares.

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

                  (b) The Company  shall not be required to issue  fractions  of
Preferred  Shares  (other than  fractions  which are  integral  multiples of one
two-hundredth of a Preferred Share) upon exercise of the Rights or to distribute
certificates  which evidence  fractional  Preferred Shares (other than fractions
which  are  integral  multiples  of one  two-hundredth  of a  Preferred  Share).
Fractions of Preferred  Shares in integral  multiples of one  two-hundredth of a
Preferred Share may, at the election of the Company,  be evidenced by depositary
receipts,  pursuant  to an  appropriate  agreement  between  the  Company  and a
depositary selected by it; provided,  that such 

                                       16
<PAGE>

agreement shall provide that the holders of such depositary  receipts shall have
all the  rights,  privileges  and  preferences  to which  they are  entitled  as
beneficial  owners  of the  Preferred  Shares  represented  by  such  depositary
receipts. In lieu of fractional Preferred Shares that are not integral multiples
of  one  two-hundredth  of a  Preferred  Share,  the  Company  shall  pay to the
registered  holders of Right  Certificates at the time such Rights are exercised
as herein  provided an amount in cash equal to the same fractions of the current
market value of one Preferred Share. For the purposes of this Section 14(b), the
current  market  value of a  Preferred  Share  shall be the  closing  price of a
Preferred  Share (as  determined  pursuant  to the  second  sentence  of Section
11(d)(i)  hereof)  for the  Trading  Day  immediately  prior to the date of such
exercise.

                  (c) The  holder  of a Right  by the  acceptance  of the  Right
expressly  waives any right to receive  fractional  Rights or 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 Right
Certificates (and, prior to the Distribution Date, the registered holders of the
Common Shares); and any registered holder of any Right Certificate (or, prior to
the  Distribution  Date, of the Common  Shares) may,  without the consent of the
Rights Agent or of the holder of any other Right  Certificate  (or, prior to the
Distribution  Date, of the Common  Shares),  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  Right
Certificate  in the  manner  provided  in  such  Right  Certificate  and in this
Agreement.  Without  limiting the  foregoing  or any  remedies  available to the
holders of Rights,  it is specifically  acknowledged  that the holders of Rights
would not have an adequate  remedy at law for any breach of this  Agreement  and
will  be  entitled  to  specific  performance  of  the  obligations  under,  and
injunctive relief against actual or threatened  violations of the obligations of
any Person subject to, this Agreement.

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

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

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

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

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

         Section 18. Compensation and Indemnity of 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
(including employees,  directors,  officers and agents of the Rights Agent) for,
and to hold it  harmless  against,  any loss,  liability  or  expense,  incurred
without  negligence,  bad faith or willful  misconduct on the part of the Rights
Agent (including employees, directors, officers and agents of the Rights Agent),
for  anything  done  or  omitted  by  the  Rights  Agent  (including  employees,
directors,  officers  and agents of the  Rights  Agent) in  connection  with the
acceptance and administration of this Agreement.

         Section 19. Merger or  Consolidation or Change of Name of Rights Agent.
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 Right  Certificates  shall have been countersigned but
not delivered, any such successor Rights Agent may adopt the countersignature of
the   predecessor   Rights  Agent  and  deliver  such  Right   Certificates   so
countersigned;  and in case at that time any of the Right Certificates shall not
have been  countersigned,  any successor Rights Agent may countersign such Right
Certificates  either in the name of the predecessor  Rights Agent or in the name
of the  successor  Rights Agent;  and in all such cases such Right  Certificates
shall  have  the full  force  provided  in the  Right  Certificates  and in this
Agreement.

         In case at any time the name of the Rights  Agent  shall be changed and
at such time any of the Right Certificates shall have been countersigned but not
delivered,  the Rights Agent may adopt the countersignature under its prior name
and deliver Right Certificates so countersigned; and in case at that time any of
the Right Certificates shall not have been  countersigned,  the Rights Agent may
countersign such Right  Certificates  either in its prior name or in its changed

                                       18
<PAGE>

name;  and in all such cases such Right  Certificates  shall have the full force
provided in the Right Certificates and in this Agreement.

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

                  (a) The Rights Agent may consult  with legal  counsel (who may
be legal counsel for the Company), and the opinion of such counsel shall be full
and complete  authorization  and protection to the Rights Agent as to any action
taken or omitted by it in good faith and in accordance with such opinion.

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

                  (c) The Rights  Agent  shall be  protected  and shall incur no
liability for any action taken, suffered or omitted by it in good faith unless a
court of  competent  jurisdiction  determines  that  the  Rights  Agent's  gross
negligence  or  willful  misconduct  was the  primary  cause  of any loss to the
Company  or any holder of a Right  Certificate  (or,  prior to the  Distribution
Date, any holder of a Right as holder of a Common Share). The Rights Agent makes
no  representation  or warranty with respect to and is not  responsible  for the
validity,  value or  availability of the Rights,  the Right  Certificates or the
Preferred Shares.

                  (d) The Rights  Agent  shall be  protected  and shall incur no
liability  for any action taken,  suffered or omitted by it in connection  with,
its  administration  of this Agreement in reliance upon any Right Certificate or
certificate  for the  Common  Shares or for  other  securities  of the  Company,
instrument of assignment or transfer, power of attorney, endorsement, affidavit,
letter, notice,  direction,  consent,  certificate,  statement or other paper or
document  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 this Section 20.

                  (e) The Rights Agent shall not be assumed to have knowledge of
and shall not be required  to take note of or act upon any fact or  circumstance
including,  without limitation, the occurrence of facts or circumstances leading
to the Shares  Acquisition Date or the Distribution Date, facts or circumstances
relating to whether any Person may be an  Affiliate or an Associate of any other
Person, facts or circumstances  relevant to an adjustment to the Purchase Price,
facts or  circumstances  relevant to events  described  in Section 13  (mergers,
etc.),  Section 23 (redemption)  and Section 24 (exchange) which may be relevant
to performance  by the rights Agent under this Agreement  unless the Company has
provided written notice thereof to the Rights Agent; and the Company agrees that
it will (i) promptly notify the Rights Agent in writing 

                                       19
<PAGE>

of the occurrence of the Shares  Acquisition Date (including the identity of the
Acquiring  Person and the date on which the Shares  Acquisition  Date occurred),
the  Distribution  Date,  the Redemption  Date,  and of any events  described in
Section 13 (merger),  and (ii) promptly provide the Rights Agent with such other
information  as the Rights Agent may reasonably  request in connection  with the
performance of its duties under this Agreement.

                  (f)    Anything   in   this    Agreement   to   the   contrary
notwithstanding,  in no event  shall the  Rights  Agent be liable  for  special,
indirect or consequential  damage or loss of any kind whatsoever  (including but
not limited to lost  profits),  even if the Rights Agent has been advised of the
likelihood of such loss or damage and regardless of the form of action, provided
the Rights Agent has acted in good faith under this Agreement.

                  (g)  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.

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

                  (i) 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.

                  (j) 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.

         Section 21. Change of Rights  Agent.  The Rights Agent or any successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon 30 days' notice in writing mailed to the Company and to each transfer agent
of the Common Shares or Preferred Shares by registered or certified mail, and to
the  holders of the Right  Certificates  by  first-class  mail.  The Company may
remove the Rights  Agent or any  successor  Rights Agent upon 30 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  Shares or  Preferred  Shares by
registered or certified  mail, and to the holders of the Right  Certificates  by
first-class  mail.  If the  Rights  Agent  shall  resign or be  removed or shall
otherwise become  incapable of acting,  the Company shall appoint a successor to
the Rights Agent.  If the Company shall fail to make such  appointment  within a
period  of 30 days  after  giving  notice of such  removal  or after it has been
notified  in writing of such  resignation  or  incapacity  by the  resigning  or
incapacitated  Rights Agent or by the holder of a Right  Certificate (who shall,
with such notice,  submit such holder's Right  Certificate for inspection by the
Company),  then the registered  holder of any Right Certificate may apply to any
court of competent  jurisdiction  for the appointment of a new Rights Agent. Any
successor  Rights  Agent,  whether  appointed by the Company or by such a court,
shall be (i) a corporation  organized and doing  business  under the laws of the
United States or of the State of California (or of any other state of the United
States so long as such  corporation  is  authorized  to do business as a banking
institution in the State of California),  in good standing,  having an office in
the  State of  California,  which is  authorized  under  such  laws to  exercise
corporate  trust or stock  transfer  powers  and is subject  to  supervision  or
examination  by  federal  or state  authority  and  which has at the time of its
appointment  as Rights  Agent a  combined  capital  and  surplus of at least $50
million dollars or (ii) a subsidiary of a corporation described in clause (i) of
this sentence.  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 Shares or Preferred  Shares,  and mail a notice thereof in writing to
the  registered  holders of the Right  Certificates.  Failure to give any notice
provided  for in this  Section 21,  however,  or any defect  therein,  shall not
affect the  legality  or validity  of the  resignation  or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Right Certificates.  Notwithstanding any of
the provisions of this  Agreement or of the Rights to the contrary,  the Company
may, at its option, issue new Right Certificates  evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the  Purchase  Price  and the  number  or kind or  class of  shares  or other
securities  or  property  purchasable  under  the  Right  Certificates  made  in
accordance  with the provisions of this  Agreement.  In addition,  following the
Distribution  Date and prior to the  redemption or expiration of the Rights,  in
connection  with the issuance or sale of Common Shares  pursuant to the exercise
of stock options or under any employee plan or arrangement or upon the exercise,
conversion or exchange of other  securities of the Company,  in each case, which
options or securities are outstanding prior to the Distribution  Date, the Board
of Directors shall 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

                                       21
<PAGE>

or this  sentence  would  create a  significant  risk of or result  in  material
adverse  tax  consequences  to the  Company  or the  Person to whom such  Rights
Certificate  would be issued or would create a significant  risk of or result in
such  options'  or  employee  plans' or  arrangements'  failing to  qualify  for
otherwise  available  special tax treatment and (ii) no such Rights  Certificate
shall be  issued  if,  and to the  extent  that,  appropriate  adjustment  shall
otherwise have been made in lieu of the issuance thereof.

         Section 23.  Redemption.

                  (a) The Board of Directors of the Company may, by a resolution
of the Board of Directors,  at its option, at any time prior to such time as any
Person  becomes an Acquiring  Person,  redeem all but not less than all the then
outstanding  Rights at a  redemption  price of $0.001 per  Right,  appropriately
adjusted  to reflect any stock  split,  stock  dividend  or similar  transaction
occurring  after  the date  hereof  (such  redemption  price  being  hereinafter
referred to as the "Redemption  Price").  After the period for redemption of the
Rights  has  expired,  the Board of  Directors  may not  extend  the  period for
redemption  of the  Rights  or  otherwise  provide  for  their  redemption.  The
redemption of the Rights by the Board of Directors may be made effective at such
time, on such basis and subject to such  conditions as the Board of Directors in
its sole discretion may establish.

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

         Section 24.  Exchange.

                  (a) The Board of  Directors of the Company may, at its option,
at any time after any Person becomes an Acquiring  Person,  authorize and direct
the  exchange  of all or part of the then  outstanding  and  exercisable  Rights
(which shall not include Rights that have become void pursuant to the provisions
of  Section  11(a)(ii)  hereof)  for  Common  Shares at an  exchange  ratio (the
"Exchange  Ratio") of one  Common  Share per Right,  appropriately  adjusted  to
reflect any stock split, stock dividend or similar  transaction  occurring after
the date hereof. Notwithstanding the foregoing, the Board of Directors shall not
be  empowered to effect such  exchange at any time after any Person  (other than
the Company,  any  Subsidiary of the Company,  



                                       22
<PAGE>

any employee  benefit plan of the Company or any such  Subsidiary  or any entity
holding  Common Shares for or pursuant to the terms of any such plan),  together
with all Affiliates and Associates of such Person,  becomes the Beneficial Owner
of a majority of the Common Shares then outstanding.

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

                  (c) In any exchange  pursuant to this Section 24, the Company,
at its option, may substitute Preferred Shares (or common stock equivalents,  as
such  term  is  defined  in  Section   11(a)(iii)   hereof)  for  Common  Shares
exchangeable for Rights, at the initial rate of one two-hundredth of a Preferred
Share (or common stock  equivalents)  for each Common  Share,  as  appropriately
adjusted to reflect  adjustments  in the voting rights of the  Preferred  Shares
pursuant  to the  terms  thereof,  so that the  fraction  of a  Preferred  Share
delivered in lieu of each Common Share shall have the same voting  rights as one
Common Share.

                  (d) In the event that  there  shall not be  sufficient  Common
Shares, Preferred Shares or common stock equivalents authorized by the Company's
certificate of incorporation  and not outstanding or subscribed for, or reserved
or otherwise  committed  for issuance for purposes  other than upon  exercise of
Rights, to permit any exchange of Rights as contemplated in accordance with this
Section  24, the  Company  shall  take all such  action as may be  necessary  to
authorize additional Common Shares, Preferred Shares or common stock equivalents
for issuance upon exchange of the Rights.

                  (e) The Company  shall not be required to issue  fractions  of
Common Shares or to distribute  certificates  which evidence  fractional  Common
Shares. In lieu of such fractional  Common Shares,  the Company shall pay to the
registered  holders  of  the  Right  Certificates  with  regard  to  which  such
fractional  Common Shares would otherwise be issuable an amount in cash equal to
the same fraction of the current per share market value of a whole Common Share.
For the purposes of this  paragraph (e), the current per share market value of a
whole Common Share shall be the closing  price of a Common Share (as  determined
pursuant to the second sentence of Section  11(d)(i) hereof) for the Trading Day
immediately prior to the date of exchange pursuant to this Section 24.

         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  Shares or to make
any other  distribution  to the holders of its  Preferred  Shares  (other than a
regular quarterly cash dividend),  (ii) to offer to the holders of its Preferred
Shares  rights or  warrants  to  subscribe  for or to  purchase  any  additional
Preferred Shares or shares of stock of any class or any other securities, rights
or options,  (iii) to effect any reclassification of its Preferred Shares (other
than a reclassification  involving only the subdivision of outstanding Preferred
Shares),  (iv) to effect any  consolidation or merger into or with, or to effect
any sale or other  transfer  (or to permit  one or more of its  Subsidiaries  to
effect any sale or other transfer), in one or more transactions,  of 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
Shares  payable  in Common  Shares or to effect a  subdivision,  combination  or
consolidation  of the Common Shares (by  reclassification  or otherwise  than by
payment of dividends in Common  Shares),  then,  in each such case,  the Company
shall  give to the  Rights  Agent  and each  holder of a Right  Certificate,  in
accordance with Section 26 hereof, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, or distribution
of  rights  or   warrants,   or  the  date  on  which   such   reclassification,
consolidation,  merger, sale, transfer, liquidation,  dissolution, or winding up
is to take place and the date of  participation  therein  by the  holders of the
Common Shares and/or Preferred Shares, if any such date is to be fixed, and such
notice shall be so given in the case of any action covered by clause (i) or (ii)
above at least 10 days prior to the record date for  determining  holders of the
Preferred Shares for purposes of such action,  and in the case of any such other
action, at least 10 days prior to the date of the taking of such proposed action
or the date of participation  therein by the holders of the Common Shares and/or
Preferred Shares, whichever shall be the earlier.

                  (b) In case any event 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 Right  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.

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

                        Delaware General Corporation Law)

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

         Elantec Semiconductor, 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 September 9, 1998:

         RESOLVED,  that pursuant to the authority  granted to and vested in the
Board of  Directors  of this  Corporation  (hereinafter  called  the  "Board  of
Directors" or the "Board") in accordance  with the provisions of the Certificate
of  Incorporation  of the  Corporation,  the Board of Directors hereby creates a
series of Preferred Stock, par value $0.01 per share (the "Preferred Stock"), of
the  Corporation  and hereby states the  designation  and number of shares,  and
fixes the relative rights, preferences, and limitations thereof as follows:

         Series A Junior Participating Preferred Stock:

         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 200,000.  Such number of shares may be  increased or decreased by
resolution of the Board of Directors;  provided,  that no decrease  shall reduce
the  number  of shares of  Series A  Preferred  Stock to a number  less than the
number of shares  then  outstanding  plus the  number  of  shares  reserved  for
issuance upon the exercise of  outstanding  options,  rights or warrants or upon
the  conversion  of  any  outstanding   securities  issued  by  the  Corporation
convertible into Series A Preferred Stock.

         Section 2. Dividends and Distributions.

                  (A)  Subject to the rights of the holders of any shares of any
series of Preferred Stock (or any other stock) ranking prior and superior to the
Series A Preferred  Stock with  respect to  dividends,  the holders of shares of
Series A Preferred Stock shall be entitled to receive,  when, as and if declared
by the  Board of  Directors  out of funds  legally  available  for the  purpose,
quarterly  dividends payable in cash on the first day of March, June,  September
and  December  in each  year  (each  such  date  being  referred  to herein as a
"Quarterly  Dividend Payment Date"),  commencing on the first Quarterly Dividend
Payment  Date  after the first  issuance  of a share or  fraction  of a share of
Series A  Preferred  Stock,  in an  amount  (if any) per share  (rounded  to the
nearest cent),  subject to the provision for adjustment  hereinafter  set forth,

<PAGE>

equal to 200 times the aggregate per share amount of all cash dividends, and 200
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,
par value $0.01 per share (the "Common Stock"),  of the Company or a subdivision
of the outstanding  shares of Common Stock (by  reclassification  or otherwise),
declared on the Common Stock since the immediately  preceding Quarterly Dividend
Payment  Date or, with respect to the first  Quarterly  Dividend  Payment  Date,
since  the  first  issuance  of any  share or  fraction  of a share of  Series A
Preferred  Stock. In the event the Corporation  shall at any time declare or pay
any dividend on the Common Stock payable in shares of Common Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the amount to which  holders  of shares of Series A  Preferred
Stock were entitled immediately prior to such event under the preceding sentence
shall be adjusted by  multiplying  such amount by a fraction,  the  numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

                  (B) The  Corporation  shall declare a dividend or distribution
on the 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).

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

         Section 3. Voting  Rights.  The holders of shares of Series A Preferred
Stock shall have the following voting rights:

                  (A) Subject to the provision for  adjustment  hereinafter  set
forth,  each share of Series A Preferred  Stock shall entitle the holder thereof
to 200  votes on all  matters  submitted  to a vote of the  stockholders  of the
Corporation.  In the event the Corporation  shall at any time declare or pay any
dividend  on the Common  Stock  payable in shares of Common  Stock,  or effect a
subdivision or combination or consolidation of the outstanding  shares of Common
Stock (by  reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, then
in each such case the  number of votes per share to which  holders  of shares of
Series A Preferred Stock were entitled  immediately prior to such event shall be
adjusted by multiplying such number by a fraction, the numerator of which is the
number of shares of Common Stock  outstanding  immediately  after such event and
the  denominator  of which is the  number of shares  of Common  Stock  that were
outstanding immediately prior to such event.

                                       2
<PAGE>

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

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

         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 shares of Series A Preferred  Stock
outstanding shall have been paid in full, the Corporation shall not:

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

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

                           (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  (as  to  dividends  and  upon   dissolution,
liquidation or winding up) to the Series A Preferred Stock.

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

         Section 6. Liquidation, Dissolution or Winding Up.

                  (A) Upon any  liquidation,  dissolution  or  winding up of the
Corporation, the holders of shares of Series A Preferred Stock shall be entitled
to receive,  prior and in  preference to any  distribution  of any assets of the
Corporation  to the holders of Common  Stock,  the amount of $1.00 per

                                       3
<PAGE>

share for each share of Series A Preferred Stock then held by them.  Thereafter,
the holders of shares of Series A  Preferred  Stock shall be entitled to receive
an  aggregate  amount  per  share,  subject  to  the  provision  for  adjustment
hereinafter set forth, equal to 200 times the aggregate amount to be distributed
per share to  holders  of shares of  Common  Stock  plus an amount  equal to any
accrued and unpaid  dividends.  In the event the  Corporation  shall at any time
declare  or pay any  dividend  on the Common  Stock  payable in shares of Common
Stock,  or  effect  a  subdivision  or  combination  or   consolidation  of  the
outstanding  shares of Common Stock (by  reclassification  or otherwise  than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock,  then in each such case the aggregate amount to which
holders of shares of Series A Preferred Stock were entitled immediately prior to
such event under the 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) If the assets of the  Corporation  legally  available  for
distribution  to the  holders  of  shares  of  Series  A  Preferred  Stock  upon
liquidation,  dissolution or winding up of the Corporation  are  insufficient to
pay the full  preferential  amount set forth in the first  sentence of paragraph
(A) above,  then the entire  assets of the  Corporation  legally  available  for
distribution  to the  holders of Series A Preferred  Stock shall be  distributed
among such holders in proportion to the shares of Series A Preferred  Stock then
held by them.

                  (C) The  foregoing  rights upon  liquidation,  dissolution  or
winding up provided to the holders of Series A Preferred  Stock shall be subject
to the rights of the  holders  of any other  series of  Preferred  Stock (or any
other stock)  ranking  prior and  superior to the Series A Preferred  Stock upon
liquidation, dissolution or winding up.

         Section 7.  Consolidation,  Merger,  etc. In case the Corporation shall
enter into any consolidation,  merger, combination or other transaction in which
the shares of Common  Stock are  exchanged  for or changed  into other  stock or
securities,  cash  and/or  other  property,  then in any such case each share of
Series A  Preferred  Stock  shall at the same  time be  similarly  exchanged  or
changed  into an amount  per  share,  subject to the  provision  for  adjustment
hereinafter  set  forth,  equal to 200  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 shares of Series A  Preferred  Stock shall be adjusted by
multiplying  such amount by a fraction,  the numerator of which is the number of
shares  of  Common  Stock  outstanding  immediately  after  such  event  and the
denominator  of  which is the  number  of  shares  of  Common  Stock  that  were
outstanding immediately prior to such event.

         Section 8. No Redemption.  The shares of Series A Preferred Stock shall
not be redeemable.

                           ELANTEC SEMICONDUCTOR, INC.

         This certifies that  ____________________ or registered assigns, is the
registered owner of the number of Rights set forth above, each of which entitles
the owner thereof, subject to the terms, provisions and conditions of the Rights
Agreement,  dated as of  September  __, 1998 (the "Rights  Agreement"),  between

per  one  two-hundredth  of a  Preferred  Share  (the  "Purchase  Price"),  upon
presentation and surrender of this Right  Certificate with the Certification and
the Form of Election to Purchase duly executed.  The number of Rights  evidenced
by this Right  Certificate (and the number of one  two-hundredths of a Preferred
Share which may be purchased  upon  exercise  hereof) set forth  above,  and the
Purchase  Price  set  forth  above,  are the  number  and  Purchase  Price as of
_________,  1998,  based on the Preferred Shares as constituted at such date. As
provided  in the  Rights  Agreement,  the  Purchase  Price and the number of one
two-hundredths  of a Preferred Share which may be purchased upon the exercise of
the Rights  evidenced by this Right  Certificate are subject to modification and
adjustment upon the happening of certain events.

         This Right  Certificate is subject to all of the terms,  provisions and
conditions of the Rights Agreement,  which terms,  provisions and conditions are
hereby  incorporated  herein by  reference  and made a part  hereof and to which
Rights Agreement  reference is hereby made for a full description of the rights,

the  Rights  Agreement  are on file at the  principal  executive  offices of the
Company and the above-mentioned offices of the Rights Agent.

         This Right Certificate, with or without other Right Certificates,  upon
surrender at the  principal  office of the Rights  Agent,  may be exchanged  for
another  Right  Certificate  or  Right  Certificates  of  like  tenor  and  date
evidencing  Rights  entitling the holder to purchase a like aggregate  number of

receive upon surrender  hereof another Right  Certificate or Right  Certificates
for the number of whole Rights not exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced

Right or Rights  evidenced  hereby  (other  than  fractions  which are  integral
multiples of one two-hundredth of a Preferred Share,  which may, at the election
of the Company, be evidenced by depository receipts), but in lieu thereof a cash
payment will be made, as provided in the Rights Agreement.

         No  holder  of this  Right  Certificate  shall be  entitled  to vote or
receive  dividends  or be deemed for any  purpose  the  holder of the  Preferred
Shares  or of any  other  securities  of the  Company  which  may at any time be
issuable on the  exercise  hereof,  nor shall  anything  contained in the Rights
Agreement or herein be construed to confer upon the holder hereof,  as such, any
of the  rights  of a  stockholder  of the  Company  or any right to vote for the
election  of  directors  or upon any matter  submitted  to  stockholders  at any
meeting thereof,  or to give or withhold consent to any corporate  action, or to

                                                                       Exhibit C


                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES


                  On  September  9,  1998,  the Board of  Directors  of  Elantec
Semiconductor,  Inc. (the "Company")  declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of common stock, par value
$0.01 per share (the "Common Shares"),  of the Company.  The dividend is payable
to  stockholders  of record  on  September  21,  1998 (the  "Record  Date").  In
addition,  one  Right  shall be issued  with  each  Common  Share  that  becomes
outstanding  (i) between the Record  Date and the  earliest of the  Distribution
Date (as  defined  below),  the date the  Rights are  redeemed  and the date the
Rights expire or (ii) following the Distribution  Date and prior to the date the
Rights are redeemed and the date the Rights expire,  pursuant to the exercise of
stock  options or under any employee plan or  arrangement  or upon the exercise,
conversion or exchange of other securities of the Corporation,  which options or
securities were outstanding prior to the Distribution  Date. Each Right entitles
the registered  holder to purchase from the Company one two-hundredth of a share
of Series A Junior Participating Preferred Stock, par value $0.01 per share (the
"Preferred Shares"),  of the Company, at a price of $25.00 per one two-hundredth
of a  Preferred  Share  (the  "Purchase  Price"),  subject  to  adjustment.  The
description and terms of the Rights are set forth in a Rights Agreement  between
the Company and ChaseMellon Shareholder Services, L.L.C., as Rights Agent.

         Until  the  earlier  to  occur  of  (i)  10  days  following  a  public
announcement  or  disclosure  that a person or group of affiliated or associated
persons (an "Acquiring  Person"),  has acquired  beneficial  ownership of 20% or
more of the  outstanding  Common  Shares or (ii) 10 business days (or such later
date as may be determined by action of the Board of Directors  prior to the time
a person or group becomes an Acquiring Person), following the announcement of an
intention to make a tender  offer or exchange  offer the  consummation  of which
would result in a person or group  becoming an Acquiring  Person (the earlier of
such dates being called the "Distribution  Date"), the Rights will be evidenced,
with  respect  to any of the Common  Share  certificates  outstanding  as of the
Record Date,  by such Common Share  certificates  with a copy of this Summary of
Rights attached thereto.  No person or group shall become an Acquiring Person if
the Board of Directors of the Company  determines in good faith that a person or
group who would otherwise be an Acquiring Person has become such  inadvertently,
and such person or group as promptly as practicable takes such actions as may be
necessary  so that  such  person  or group  would no  longer  be  considered  an
Acquiring Person.

         The Rights Agreement  provides that,  until the Distribution  Date, the
Rights  will be  transferred  with and only with the  Common  Shares.  Until the
Distribution  Date (or earlier  redemption  or  expiration  of the Rights),  new
Common Share  certificates  issued after the Record Date,  upon  transfer or new
issuance of Common  Shares,  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 Shares 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 Shares  represented  by such
certificate.  As soon as practicable  following the Distribution Date,  separate
certificates  evidencing  the Rights  will be mailed to holders of record of the
Common  Shares as of the Close of  Business  on the  Distribution  Date and such
separate  certificates  alone will  evidence  the Rights.  If Common  Shares are
issued or sold  after the  Distribution  Date (but  prior to the  redemption  or
expiration  of the Rights) in  connection  with the exercise of stock options or

<PAGE>

upon the  exercise,  conversion  or exchange of other  securities of the Company
outstanding  prior  to the  Distribution  Date,  the  Company  shall  issue  the
appropriate number of Rights in connection with such issuance or sale.

         The Rights are not exercisable until the Distribution  Date. The Rights
will expire on  September  14, 2008 (the "Final  Expiration  Date"),  unless the
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 Preferred Shares 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
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or  warrants  to  subscribe  for or  purchase  Preferred  Shares at a price,  or
securities  convertible into Preferred Shares with a conversion price, less than
the  then  current  market  price of the  Preferred  Shares  or  (iii)  upon the
distribution to holders of the Preferred  Shares of evidences of indebtedness or
assets  (excluding  regular  periodic  cash  dividends  paid out of  earnings or
retained  earnings or dividends  payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

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

         Preferred  Shares  purchasable  upon exercise of the Rights will not be
redeemable.  Each  Preferred  Share will be  entitled  to a  quarterly  dividend
payment of 200 times the  dividend  declared per Common  Share.  In the event of
liquidation,  each Preferred Share will be entitled to a $2.00  preference,  and
thereafter the holders of the Preferred  Shares will be entitled to an aggregate
payment of 200 times the aggregate payment made per Common Share. Each Preferred
Share will have 200 votes,  voting together with the Common Shares.  Finally, in
the event of any merger,  consolidation  or other  transaction  in which  Common
Shares are exchanged, each Preferred Share will be entitled to receive 200 times
the amount  received per Common  Share.  These rights are protected by customary
anti-dilution provisions.

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

         In the event that any  person or group  becomes  an  Acquiring  Person,
unless the event causing the Designated  Percentage  threshold to be crossed and
the  person  or group  to  thereby  become  an  Acquiring  Person  is a  merger,
acquisition or other business combination described in the next paragraph,  each
holder of a Right, other than Rights  beneficially owned by the Acquiring Person
(which will thereafter be void),  will thereafter have the right to receive upon
exercise  that number of Common  Shares  having a market  value of two times the
exercise  price of the Right on the terms and conditions set forth in the Rights
Agreement.  If the Company does not have  authorized but unissued  Common Shares
sufficient  to satisfy such  obligation to issue Common  Shares,  the Company is
obligated to deliver upon payment of the exercise  price of a Right an amount of
cash or other securities  equivalent in value to the Common Shares issuable upon
exercise of a Right.

         In the event that any person or group  becomes an Acquiring  Person and
the  Company  merges  into or  engages  in certain  other  business  combination
transactions with an Acquiring Person, or 50% or

                                       2
<PAGE>

more of its  consolidated  assets  or  earning  power  are sold to an  Acquiring
Person,  each  holder of a Right,  other than  Rights  beneficially  owned by an
Acquiring Person,  will thereafter have the right to receive,  upon the exercise
thereof at the then current  exercise price of the Right,  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 Right.

         At any time after any person or group  becomes an Acquiring  Person and
prior  to the  acquisition  by  such  person  or  group  of 50% or  more  of the
outstanding  Common  Shares,  the Board of Directors of the Company may exchange
the Rights  (other than Rights owned by the  Acquiring  Person),  in whole or in
part,  at an  exchange  ratio of one Common  Share (or one  two-hundredths  of a
Preferred  Share, or of a share of a class or series of the Company's  preferred
stock having equivalent  rights,  preferences and privileges) 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  Preferred  Shares will be issued (other than
fractions  which are  integral  multiples  of one  two-hundredth  of a Preferred
Share,  which may, at the  election of the Company,  be evidenced by  depository
receipts) and in lieu  thereof,  an adjustment in cash will be made based on the
market price of the  Preferred  Shares on the last trading day prior to the date
of exercise.

         At any  time  prior  to such  time as a  person  or  group  becomes  an
Acquiring Person, the Board of Directors of the Company may redeem the Rights in
whole,  but not in  part,  at a  redemption  price  of  $0.001  per  Right.  The
redemption  of the Rights may be made  effective at such time, on such basis and
with  such  conditions  as the Board of  Directors  in its sole  discretion  may
establish.  After the period for redemption of the Rights has expired, the Board
may not amend the Rights  Agreement to extend the period for  redemption  of the
Rights. 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 terms of the Rights may be amended by a resolution  of the Board of
Directors without the consent of the holders of the Rights, except that from and
after such time as any  person or group  becomes an  Acquiring  Person,  no such
amendment may adversely affect the interests of the holders of the Rights (other
than an Acquiring Person).

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.

         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 dated
September 16, 1998. 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.
