Item 1.     Description of Securities to be Registered.
            ------------------------------------------

            On  September  25,  1996,  pursuant  to a  Preferred  Shares  Rights

Agreement  (the "Rights  Agreement")  between  Silicon  Valley  Group,  Inc (the

"Company") and ChaseMellon  Shareholder  Services,  L.L.C., as Rights Agent (the

"Rights  Agent"),  the Company's  Board of Directors  declared a dividend of one

right (a "Right") to purchase one one-thousandth share of the Company's Series A

Participating  Preferred Stock ("Series A Preferred") for each outstanding share

of Common Stock, $.01 par value ("Common Shares"),  of the Company. The dividend

is payable on October 15, 1996 (the "Record Date") to  stockholders of record as

of the close of business on that date. Each Right entitles the registered holder

to purchase from the Company one one-thousandth of a share of Series A Preferred

at an exercise price of $125.00 (the "Purchase Price"), subject to adjustment.

      The following  summary of the principal terms of the Rights Agreement is a

general  description only and is subject to the detailed terms and conditions of

the Rights Agreement. A copy of the Rights Agreement is attached as Exhibit 1 to

this Registration Statement and is incorporated herein by reference.




















                                       -2-



<PAGE>



Rights Evidenced by Common Share Certificates
- ---------------------------------------------


      The Rights will not be exercisable  until the  Distribution  Date (defined

below).  Certificates for the Rights ("Rights Certificates") will not be sent to

stockholders  and the Rights  will  attach to and trade only  together  with the

Common Shares. Accordingly,  Common Share certificates outstanding on the Record

Date will evidence the Rights  related  thereto,  and Common Share  certificates

issued  after the Record Date will contain a notation  incorporating  the Rights

Agreement by reference.  Until the Distribution  Date (or earlier  redemption or

expiration  of the Rights),  the  surrender or transfer of any  certificates for

Common Shares outstanding as of the Record Date, even without notation or a copy

of the  Summary of Rights  being  attached  thereto,  will also  constitute  the

transfer of the Rights  associated  with the Common Shares  represented  by such

certificate.


Distribution Date
- -----------------


      The Rights will separate from the Common Shares,  Rights Certificates will

be  issued  and  the  Rights  will  become   exercisable  upon  such  date  (the

"Distribution  Date")  which is the earlier of: (i) the close of business on the

tenth day (or such later date as may be  determined  by action of a majority  of

the  Continuing  Directors (as defined in Section 1(g) of the Rights  Agreement)

then in office) after the Shares Acquisition Date (as defined in Section 1(u) of

the Rights  Agreement)  or, if the tenth day after the Shares  Acquisition  Date

occurs before the Record Date,  the close of business on the Record Date or (ii)

the close of business on the tenth day (or such later date as may be  determined

by action of a majority of Continuing  Directors  then in office) after the date



                                       -3-

<PAGE>


that a tender or exchange offer by any Person (as defined in Section 1(m) of the

Rights Agreement) is first published or sent or given within the meaning of Rule

14d-2(a) of the General Rules and Regulations under the Securities  Exchange Act

of 1934, if, assuming the successful  consummation thereof, such Person would be

the  Beneficial  Owner of 15% or more of the  Common  Shares  then  outstanding,

subject to Section 1(a) of the Rights Agreement.



Issuance of Rights Certificates; Expiration of Rights
- -----------------------------------------------------


      As soon as practicable  following the Distribution  Date,  separate Rights

Certificates  will be mailed to holders of record of the Common Shares as of the

close of business on the Distribution Date and such separate Rights Certificates

alone will evidence the Rights from and after the Distribution  Date. All Common

Shares issued prior to the Distribution Date will be issued with Rights.  Common

Shares  issued  after the  Distribution  Date may be issued  with Rights if such

shares are issued (i) upon the conversion of outstanding  convertible debentures

or any  other  convertible  securities  issued  after  adoption  of  the  Rights

Agreement or (ii)  pursuant to the exercise of stock  options or under  employee

benefit plans or arrangements  unless as a result of such issuance such options,

plans  or  arrangements  would  not  qualify  (or  would be made at risk for not

qualifying) for otherwise  available special tax treatment.  Except as otherwise

determined  by the Board of  Directors,  no other Common Shares issued after the

Distribution  Date will be issued  with  Rights.  The Rights  will expire on the

earliest  of (i)  September  25,  2006  (the  "Final  Expiration  Date") or (ii)

redemption or exchange of the Rights as described below.



                                       -4-



<PAGE>



Initial Exercise of the Rights
- ------------------------------


      Following  the  Distribution  Date,  and until one of the  further  events

described  below,  holders of the  Rights  will be  entitled  to  receive,  upon

exercise and the payment of $125.00 per Right, one  one-thousandth  share of the

Series A  Preferred.  In the event  that the  Company  does not have  sufficient

Common Shares  authorized  and  available  for issuance  upon  conversion of the

Series A  Preferred  issuable  upon  exercise of the Rights such that all of the

Rights may be exercised,  or the Board decides that such action is necessary and


not contrary to the interests of Rights holders, the Company may instead substi-

tute cash, a reduction in the Purchase Price,  other assets or other  securities

of the Company for the Common Shares  issuable  upon  conversion of the Series A

Preferred for which the Rights would have been exercisable.


Right to Buy Company Common Shares
- ----------------------------------


      Unless the Rights are  earlier  redeemed,  in the event that an  Acquiring

Person  becomes  the beneficial  owner  of 15% or more of the  Company's  Common

Shares then outstanding,  then proper provision will be made so that each holder

of a  Right  which  has  not  theretofore  been  exercised  (other  than  Rights

beneficially owned by the Acquiring Person,  which will thereafter be void) will

thereafter  have the right to receive,  upon  exercise,  Common  Shares having a

value  equal  to two  times  the  Purchase  Price.  Rights  are not  exercisable

following the  occurrence of an event as described  above until such time as the

Rights are no longer redeemable by the Company as set forth below.




                                       -5-


<PAGE>



Right to Buy Acquiring Company Stock
- ------------------------------------


      Similarly,  unless the Rights are  earlier  redeemed,  in the event  that,

after an Acquiring  Person  becomes the  beneficial  owner of 15% or more of the

Company's  Common  Shares  then  outstanding,  (i) the  Company is acquired in a

merger or other  business  combination  transaction,  or (ii) 50% or more of the

Company's  consolidated  assets  or  earning  power  are  sold  (other  than  in

transactions in the ordinary course of business),  proper provision must be made

so that each holder of a Right which has not thereto fore been exercised  (other

than Rights beneficially owned by the Acquiring Person, which will thereafter be

void) will thereafter have the right to receive, upon exercise, shares of common

stock of the  acquiring  company  having a value equal to two times the Purchase

Price.


Exchange Provision
- ------------------


      At any time after the acquisition by an Acquiring Person of 15% or more of

the Company's  outstanding  Common Shares and prior to the  acquisition  by such

Acquiring Person of 50% or more of the Company's  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 per Right.








                                       -6-



<PAGE>



Redemption
- ----------


      At any time on or prior to the close of business on the earlier of (i) the

10th  day  following  the  acquisition  by  an  Acquiring   Person  (the  "Share

Acquisition  Date") or such later date as may be determined by a majority of the

Continuing  Directors and publicly  announced by the Company,  or (ii) the Final

Expiration Date of the Rights,  the Company may redeem the Rights in whole,  but

not in part, at a price of $0.01 per Right.


Adjustments to Prevent Dilution
- -------------------------------



      The Purchase Price payable, the number of Rights, and the number of Series

A Preferred  or Common  Shares or other  securities  or property  issuable  upon

exercise of the Rights are subject to adjustment from time to time in connection

with the dilutive issuances by the Company as set forth in the Rights Agreement.

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.


Cash Paid Instead of Issuing Fractional Shares
- ----------------------------------------------


      No  fractional  portion less than  integral  multiples of one Common Share

will be issued upon  exercise of a Right and in lieu  thereof,  an adjustment in

cash will be made  based on the market  price of the  Common  Shares on the last

trading date immediately prior to the date of exercise.



                                       -7-



<PAGE>



No Stockholders' Rights Prior to Exercise
- -----------------------------------------


      Until a Right is  exercised,  the holder  thereof,  as such,  will have no

rights as a stockholder  of the Company  (other than any rights  resulting  from

such holder's ownership of Common Shares),  including,  without limitation,  the

right to vote or to receive dividends.


Amendment of Rights Agreement
- -----------------------------


      The provisions of the Rights  Agreement may be  supplemented or amended by

the Board of  Directors in any manner prior to the close of business on the date

an Acquiring Person becomes the beneficial owner of 15% or more of the Company's

Common Shares then  outstanding  without the approval of Rights  holders.  After

such date, the provisions of the Rights Agreement may be amended by the Board in


order to cure any ambiguity,  defect or inconsistency,  to make changes which do

not adversely affect the interests of holders of Rights (excluding the interests

of any  Acquiring  Person),  or to shorten or lengthen any time period under the

Rights Agreement; provided, however, that no amendment to adjust the time period

governing redemption shall be made once the Rights are no longer redeemable.


Rights and Preferences of the Series A Preferred
- ------------------------------------------------


      Series A  Preferred  purchasable  upon  exercise of the Rights will not be

redeemable.  Each share of Series A Preferred  will be entitled to an  aggregate






                                       -8-



<PAGE>

dividend of 1,000 times the dividend  declared per Common Share. In the event of

liquidation, the holders of the Series A Preferred will be entitled to a minimum

preferential  liquidation  payment  equal to $125.00  per share,  plus an amount

equal to accrued and unpaid dividends and distributions thereon,  whether or not

declared, to the date of such payment.  Following the payment of such amount, no

additional  distributions  shall be made to the  holders  of  shares of Series A


Preferred  unless,  prior  thereto,  the  holders  of Common  Shares  shall have

received an amount per share  equal to the  quotient  obtained  by dividing  the

amount paid to holders of Series A Preferred by 1,000.  Following the payment of

each of these  amounts,  holders  of Series A  Preferred  and  holders of Common

Shares shall  receive  their  ratable and  proportionate  share of the remaining

assets to be distributed in the ratio of 1000 to 1 with respect to such Series A

Preferred and Common Shares, on a per share basis,  respectively.  Each share of

Series A  Preferred  will have  1,000  votes,  voting  together  with the Common

Shares. These rights are protected by customary anti-dilution provisions.

      Because of the nature of the  dividend,  liquidation  and voting rights of

the shares of Series A Preferred,  the value of the one one-thousandth  interest

in a share of Series A Preferred  purchasable upon exercise of each Right should

approximate the value of one Common Share.


Certain Anti-takeover Effects
- -----------------------------


      The Rights  approved by the Board are designed to protect and maximize the

value of the  outstanding  equity  interests  in the  Company in the event of an

unsolicited  attempt by an acquiror to take over the Company,  in a manner or on

terms not  approved  by the Board of  Directors.  Takeover  attempts  frequently


include  coercive  tactics to deprive the  Company's  Board of Directors and its

stockholders of any real opportunity to determine the future of the Company. The

                                       -9-

<PAGE>


Rights have been declared by the Board in order to deter such tactics, including

a gradual accumulation of shares in the open market of a 15% or greater position

to be followed by a merger or a partial or two-tier  tender  offer that does not

treat all stockholders  equally.  These tactics unfairly pressure  stockholders,

force them out of their  investment  without giving them meaningful  choices and

deprive them of the full value of their shares.

      The Rights are not  intended to prevent a takeover of the Company and will

not do so. The Rights may be redeemed  by the Company at $0.01 per Right  within

ten  days  (or  such  later  date  as may be  determined  by a  majority  of the

Continuing  Directors)  after the  accumulation  of 15% or more of the Company's

shares by a single  acquiror  or  group.  Accordingly,  the  Rights  should  not

interfere  with any  merger or  business  combination  approved  by the Board of

Directors.

      Issuance of the Rights does not in any way weaken the  financial  strength

of the Company or interfere with its business plans.  The issuance of the Rights

themselves has no dilutive effect,  will not affect reported earnings per share,

should not be taxable to the Company or to its stockholders, and will not change

the way in which the Company's shares are presently traded.  The Company's Board

of Directors  believes that the Rights represent a sound and reasonable means of

addressing  the  complex  issues of  corporate  policy  created  by the  current

takeover environment.

      However,  the Rights may have the effect of  rendering  more  difficult or

discouraging  an acquisition  of the Company deemed  undesirable by the Board of

Directors.  The Rights may cause substantial  dilution to a person or group that

attempts  to acquire  the  Company on terms or in a manner not  approved  by the

Company's Board of Directors,  except pursuant to an offer  conditioned upon the

negation, purchase or redemption of the Rights.

                                RIGHTS AGREEMENT


      Agreement,  dated as of September 25, 1996,  between Silicon Valley Group,
Inc.,  a Delaware  corporation  (the  "Company"),  and  ChaseMellon  Shareholder
Services, L.L.C. (the "Rights Agent").

      On September 25, 1996 (the "Rights Dividend  Declaration Date"), the Board
of Directors of the Company  authorized and declared a dividend of one Preferred
Share purchase right (a "Right") for each Common Share (as hereinafter  defined)
of the Company outstanding as of the Close of Business (as hereinafter  defined)
on October 15, 1996 (the "Record Date"),  each Right  representing  the right to
purchase one one-thousandth of a share of Series A Participating Preferred Stock
(as such number may be adjusted  pursuant to the provisions of this  Agreement),
having  the  rights,  preferences  and  privileges  set  forth  in the  form  of
Certificate  of Designation  of Rights,  Preferences  and Privileges of Series A
Participating  Preferred  Stock attached hereto as Exhibit A, upon the terms and
subject to the conditions herein set forth, and further  authorized and directed
the  issuance  of one Right (as such  number  may be  adjusted  pursuant  to the
provisions  of this  Agreement)  with  respect to each  Common  Share that shall
become  outstanding  between the Record Date and the earlier of the Distribution
Date and the Expiration  Date (as such terms are  hereinafter  defined),  and in
certain circumstances after the Distribution Date.

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

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

            (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 15% or more of the Common Shares then outstanding,  but shall not include the
Company,  any  subsidiary  of the Company or 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. Notwithstanding the foregoing, no
Person  shall  be  deemed  to be an  Acquiring  Person (i) 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 to 15% or more of the Common  Shares of the  Company  then
outstanding;  provided,  however,  that if a Person shall become the  Beneficial
Owner of 15% or more of the Common  Shares of the Company  then  outstanding  by
reason of share  purchases of the Company and shall,  after such share purchases
of 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, or (ii)
if the Board of Directors of the  Company determines in good faith that a Person
who  would  otherwise  be  an  "Acquiring  Person", as  defined  pursuant to the
provisions of this paragraph (a),  has  become  such  inadvertently  (including,
without limitation,  because  (A) such Person was unaware  that it  beneficially
owned a percentage of the  Common  Shares that would otherwise cause such Person
to  be  an  "Acquiring  Person",  as  defined pursuant to the provisions of this
paragraph (a), or (B)  such  Person was aware of the extent of the Common Shares
it beneficially owned but had no actual knowledge of the  consequences  of  such
beneficial ownership under this Agreement) and without any intention of changing



                                       -1-


<PAGE>
or influencing control of the Company, and if such Person divested or divests as
promptly as practicable a sufficient number of Common Shares so that such Person
would no longer be an "Acquiring  Person", as defined pursuant to the provisions
of this  paragraph  (a),  then such Person  shall not be deemed to be or to have
become an "Acquiring  Person" for any purposes of this Agreement;  or (iii) such
Person reports  Beneficial  Ownership of Common Shares on Schedule 13G under the
Securities Exchange Act of 1934, as amended, representing more than 15% but less
than 20% of the Common Shares of the Company then  outstanding and utilizes said
Schedule 13G in lieu of a Schedule 13D for such reporting on the basis that such
Person  has  no intention  of  changing  or  influencing control of the Company;
provided, further, however, that if such Person who reports Beneficial Ownership
on Schedule 13G in accordance with the  foregoing  subsequently files a Schedule
13D on the basis that such Person intends to change or  influence control of the
Company,  such  Person  shall  be deemed an Acquiring Person as of the date such
person files such Schedule 13D.

            (b) "Affiliate" and "Associate"  shall have the respective  meanings
ascribed to such terms in Rule 12b-2 of the General Rules and Regulations  under
the  Securities  Exchange Act of 1934, as amended (the  "Exchange  Act"),  as in
effect on the date of this Agreement.

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

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

                  (ii) which such Person or any of such  Person's  Affiliates or
Associates  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),  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  pursuant to this Section
1(c)(ii)(A)  to be  the  Beneficial  Owner  of,  or  to  beneficially  own,  (1)
securities  tendered pursuant to a tender or exchange offer made by or on behalf
of such  Person or any of such  Person's  Affiliates  or  Associates  until such
tendered  securities  are accepted for purchase or exchange,  or (2)  securities
which a Person or any of such Person's Affiliates or Associates may be deemed to
have the right to acquire pursuant to any merger or other acquisition  agreement
between  the  Company  and  such  Person  (or one or more of its  Affiliates  or
Associates) if such agreement has been approved by the Board of Directors of the
Company  prior to there  being an  Acquiring  Person;  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 under this Section  1(c)(ii)(B)  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 of the Exchange Act and (2) is not also then  reportable on Schedule
13D under the Exchange Act (or any comparable or successor report); or

                  (iii) which are beneficially owned, directly or indirectly, by
any other Person (or any Affiliate or Associate  thereof) with which such Person

                                       -2-

<PAGE>
or any of such Person's Affiliates or Associates has any agreement,  arrangement
or  understanding,  whether or not in writing (other than  customary  agreements
with and between  underwriters and  selling group members with respect to a bona
fide public  offering of  securities)  for the  purpose of  acquiring,  holding,
voting (except to the extent contemplated by the proviso to Section 1(c)(ii)(B))
or disposing of any  securities of the Company;  PROVIDED, HOWEVER,  that in  no
case shall an officer or director  of the  Company be deemed (x) the  Beneficial
Owner of any securities beneficially owned by another officer or director of the
Company solely by reason of actions undertaken by such persons in their capacity
as  officers  or  directors  of the  Company  or (y)  the  Beneficial  Owner  of
securities  held of record by the trustee of any  employee  benefit  plan of the
Company or any  Subsidiary of the Company for the benefit of any employee of the
Company or any Subsidiary of the Company, other than the officer or director, by
reason of any  influence  that such officer or director may have over the voting
of the securities held in the plan.

            (d) "Business Day" shall mean any day other than a Saturday,  Sunday
or a day on which banking institutions in 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.,
California  time, on such date; PROVIDED, HOWEVER,  that  if  such date is not a
Business Day it shall mean 5:00 P.M.,  California  time, on the next  succeeding

Directors of the Company,  while a member of the Board,  who is not an Acquiring
Person, or an Affiliate or Associate of an Acquiring Person, or a representative
of an  Acquiring  Person or of any such  Affiliate or  Associate,  and who was a
member of the Board prior to there being an Acquiring Person, or (ii) any Person
who subsequently becomes a member of the Board, while a member of the Board, who

Rights Agent to act as agent for the Company and the holders of the Rights (who,
in accordance with Section 3 hereof,  shall prior to the Distribution  Date also

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.  ISSUANCE OF RIGHTS CERTIFICATES.

            (a) Until the  Distribution  Date,  (i) the Rights will be evidenced
(subject to the provisions of Sections 3(b) and 3(c) hereof) by the certificates
for  Common  Shares  registered  in the  names  of the  holders  thereof  (which
certificates shall also be deemed to be Rights Certificates) and not by separate
Rights  Certificates and (ii) the right to receive Rights  Certificates  will be
transferable  only in connection  with the transfer of Common Shares.  Until the
earlier of the  Distribution  Date or the  Expiration  Date,  the  surrender for
transfer  of such  certificates  for Common  Shares  shall also  constitute  the
surrender  for  transfer  of  the  Rights  associated  with  the  Common  Shares
represented  thereby.  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,  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 Rights  Certificate,  in
substantially the form of Exhibit B hereto (a "Rights Certificate"),  evidencing
one Right for each  Common  Share so held,  subject to  adjustment  as  provided
herein. In the event that an adjustment in the number of Rights per Common Share
has been made  pursuant  to Section  11(a)(i),  Section  11(i) or Section  11(p)
hereof, then at the time of distribution of the Rights Certificates, the Company
shall make the necessary and  appropriate  rounding  adjustments  (in accordance

                                       -5-

<PAGE>


with Section 14(a) hereof) so that Rights  Certificates  representing only whole
numbers of Rights  are  distributed  and cash is paid in lieu of any  fractional
Rights. As of the Distribution Date, the Rights will be evidenced solely by such
Rights  Certificates  and  may be  transferred  by the  transfer  of the  Rights
Certificates as permitted hereby,  separately and apart from any transfer of one
or more Common Shares, and the holders of such Rights  Certificates as listed in
the records of the Company or any  transfer  agent or  registrar  for the Rights
shall be the record holders thereof.

            (b) On the Record  Date or as soon as  practicable  thereafter,  the
Company  will send a copy of a Summary  of Rights 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.

            (c) Unless the Board of Directors by resolution adopted at or before
the time of the issuance (including pursuant to the exercise of rights under the
Company's benefit plans) of any Common Shares specifies to the contrary,  Rights
shall be issued in respect of all Common Shares that are issued after the Record
Date but prior to the earlier of the  Distribution  Date or the Expiration  Date
or,  in  certain  circumstances   provided  in  Section  22  hereof,  after  the
Distribution  Date.  Certificates  representing such Common Shares shall also be
deemed to be certificates for Rights, and shall bear the following legend:

      This  certificate also evidences and entitles the holder hereof to certain
      rights as set forth in a Rights  Agreement  between  Silicon Valley Group,
      Inc. and ChaseMellon  Shareholder  Services,  L.L.C., as the Rights Agent,
      dated as of September  25,  1996,  as it may be amended from time to time,
      (the  "Rights  Agreement"),  the  terms of which are  hereby  incorporated
      herein  by  reference  and a copy of  which  is on  file at the  principal
      executive   offices  of  Silicon   Valley   Group,   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.  Silicon  Valley Group,  Inc. will mail to the holder of this
      certificate a copy of  the Rights  Agreement  without charge after receipt
      of a written request  therefor.  Under certain  circumstances set forth in
      the Rights Agreement, Rights issued to, or held by, any Person who is, was
      or becomes an Acquiring  Person or any Affiliate or Associate  thereof (as
      such terms are defined in the Rights Agreement), whether currently held by
      or on behalf of such Person or by any subsequent  holder,  may become null
      and void.      

With respect to such  certificates  containing the foregoing  legend,  until the
earlier of (i) the  Distribution  Date or (ii) the  Expiration  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 canceled and
retired  so that the  Company  shall not be  entitled  to  exercise  any  Rights
associated with the Common Shares which are no longer outstanding.

                                     -6-

      Section 4.  FORM OF RIGHTS CERTIFICATES.

            (a) The Rights  Certificates  (and the forms of election to purchase
Common Shares and of assignment to be printed on the reverse  thereof)  shall be
substantially  in the form of  Exhibit  A  hereto  and may  have  such  marks of
identification  or  designation  and such  legends,  summaries  or  endorsements
printed thereon as the Company may deem  appropriate and as are not inconsistent
with the provisions of this Agreement,  or as may be required to comply with any
applicable law or with any rule or regulation made pursuant  thereto or with any
rule or regulation of any stock exchange or a national  market system,  on which
the Rights may from time to time be listed or included,  or to conform to usage.
Subject  to the  provisions  of Section  11 and  Section  22 hereof,  the Rights
Certificates, whenever distri buted, shall be dated as of the Record Date (or in
the case of Rights  issued with respect to Common  Shares  issued by the Company
after the Record Date, as of the date of issuance of such Common  Shares) and on
their  face  shall  entitle  the  holders  thereof to  purchase  such  number of
one-thousandths  of a Preferred Share as shall be set forth therein at the price
set forth therein (such  exercise  price per one  one-thousandth  of a Preferred
Share being  hereinafter  referred to as the "Purchase  Price" and the aggregate
exercise price of all Preferred Shares issuable upon exercise of one Right being
hereinafter  referred to as the "Total Exercise Price"), but the number and type
of securities purchasable upon the exercise of each Right and the Purchase Price
shall be subject to adjustment as provided herein.

            (b) Any  Rights  Certificate  issued  pursuant  to  Section  3(a) or
Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring
Person or any Associate or Affiliate of an Acquiring  Person,  (ii) a transferee
of an Acquiring  Person (or of any such  Associate or  Affiliate)  who becomes a
transferee  after the Acquiring  Person becomes such or (iii) a transferee of an
Acquiring  Person  (or of  any  such  Associate  or  Affiliate)  who  becomes  a
transferee prior to or concurrently  with the Acquiring Person becoming such and
receives  such  Rights  pursuant  to either (A) a transfer  (whether  or not for
consideration)  from the Acquiring Person to holders of equity interests in such
Acquiring  Person  or to any  Person  with whom such  Acquiring  Person  has any
continuing  agreement,  arrangement or  understanding  regarding the transferred
Rights or (B) a  transfer  which  the  Board of  Directors  of the  Company  has
determined  is part of a  plan,  arrangement  or  understanding  which  has as a
primary  purpose or effect the avoidance of Section 7(e) hereof,  and any Rights
Certificate  issued  pursuant to Section 6 or Section 11 hereof  upon  transfer,
exchange,  replacement or adjustment of any other Rights Certificate referred to
in this sentence, shall contain (to the extent feasible) the following legend:

      The Rights represented by this Rights Certificate are or were beneficially
      owned by a Person who was or became an Acquiring Person or an Affiliate or
      Associate of an Acquiring  Person (as such terms are defined in the Rights
      Agreement).   Accordingly,   this  Rights   Certificate   and  the  Rights
      represented hereby may become null and void in the circumstances specified
      in Section 7(e) of the Rights Agreement.

      Section 5.  COUNTERSIGNATURE AND REGISTRATION.

            (a) The  Rights  Certificates  shall be  executed  on  behalf of the
Company by its Chairman of the Board, its Chief Executive Officer, its President
or any Vice  President,  either manually or by facsimile  signature,  and by the
Secretary or an  Assistant  Secretary  of  the  Company,  either  manually or by

                                       -7-

<PAGE>

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

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

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

            (a) Subject to the provisions of Sections 7(e), 14 and 24 hereof, at
any time after the Close of Business on the  Distribution  Date, and at or prior
to the Close of Business  on the  Expiration  Date,  any Rights  Certificate  or
Rights  Certificates  may be  transferred,  split up,  combined or exchanged for
another  Rights  Certificate  or Rights  Certificates,  entitling the registered
holder to purchase a like number of  one-thousandths  of a Preferred  Share (or,
following a Triggering  Event,  other  securities,  cash or other assets, as the
case may be) as the Rights Certificate or Rights  Certificates  surrendered then
entitled such holder to purchase.  Any registered  holder  desiring to transfer,
split up,  combine or exchange  any Rights  Certificate  or Rights  Certificates
shall make such  request in writing  delivered  to the Rights  Agent,  and shall
surrender the Rights Certificate or Rights Certificates to be transferred, split
up, combined or exchanged at the office of the Rights Agent  designated for such
purpose. Neither the Rights Agent nor the Company shall be obligated to take any
action  whatsoever with respect to the transfer of any such  surrendered  Rights
Certificate  until the  registered  holder shall have  completed  and signed the
certificate  contained  in the form of  assignment  on the reverse  side of such
Rights  Certificate  and shall have  provided  such  additional  evidence of the
identity of the Beneficial Owner (or former  Beneficial  Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent shall, subject to Sections 7(e), 14 and 24 hereof, countersign and deliver
to the person entitled thereto a Rights Certificate or Rights  Certificates,  as
the case may be, as so  requested.  The  Company  may  require  payment of a sum
sufficient  to cover  any tax or  governmental  charge  that may be  imposed  in
connection  with any  transfer,  split up,  combination  or  exchange  of Rights
Certificates.

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

                                       -8-

<PAGE>

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

      Section 7.  EXERCISE OF RIGHTS; PURCHASE PRICE; EXPIRATION DATE OF RIGHTS.

            (a) Subject to Sections 7(e), 23(b) and 24(b) hereof, the registered
holder of any Rights  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 Rights  Certificate,  with the form of
election to purchase on the reverse side thereof  duly  executed,  to the Rights
Agent at the office of the Rights Agent  designated  for such purpose,  together
with payment of the Purchase Price for each  one-thousandth of a Preferred Share
as to which the Rights are exercised, at or prior to the Expiration Date.

            (b) The Purchase Price for each  one-thousandth of a Preferred Share
issuable  pursuant to the  exercise of a Right  shall  initially  be One Hundred
Twenty-Five Dollars ($125.00),  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 Rights  Certificate  representing  exercisable
Rights,  with the form of election to purchase  duly  executed,  accompanied  by
payment of the Purchase Price for the number of  one-thousandths  of a Preferred
Share (or other securities or property,  as the case may be) to be purchased and
an amount equal to any applicable transfer tax required to be paid by the holder
of such Rights  Certificate  in accordance  with Section 9 hereof in cash, or by
certified  check or cashier's  check  payable to the order of the  Company,  the
Rights Agent shall, subject to Section 20(k) hereof,  thereupon promptly (i) (A)
requisition  from any transfer agent of the Preferred Shares (or make available,
if the  Rights  Agent  is  the  transfer  agent  for  the  Preferred  Shares)  a
certificate or  certificates  for the number of one-thousandths  of  a Preferred
Share to be purchased and the Company hereby irrevocably authorizes its transfer
agent to comply with all such  requests or (B) if the Company shall have elected
to deposit the total number of  one-thousandths  of a Preferred  Share  issuable
upon exercise of the Rights hereunder with a depositary agent,  requisition from
the  depositary  agent  of  depositary  receipts  representing  such  number  of
one-thousandths  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  shares in accordance  with Section 14 hereof,  (iii)
after receipt of such certificates or depositary receipts,  cause the same to be
delivered  to or  upon  the  order  of the  registered  holder  of  such  Rights
Certificate,  registered  in such  name or  names as may be  designated  by such
holder and (iv) when appropriate, after receipt thereof, deliver such cash to or
upon the order of the registered holder of such Rights Certificate.  The payment
of the  Purchase  Price  (as such  amount  may be  reduced  (including  to zero)
pursuant to Section  11(a)(iv)  hereof) may be made in cash or by certified bank
check or bank draft  payable to the order of the Company.  In the event that the
Company is obligated to issue other  securities of the Company,  pay cash and/or
distribute other  property  pursuant to  Section 11(a) hereof, the  Company will

                                       -9-

<PAGE>

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

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

            (e) Notwithstanding anything in this Agreement to the contrary, from
and after the first  occurrence of a Triggering Event or a Section 13 Event, any
Rights  beneficially  owned  by (i)  an  Acquiring  Person  or an  Associate  or
Affiliate of an Acquiring  Person,  (ii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) who becomes a transferee after the Acquiring
Person  becomes such (a "Post  Transferee"),  (iii) a transferee of an Acquiring
Person (or of any such Associate or Affiliate) who becomes a transferee prior to
or concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer  (whether or not for  consideration)  from the
Acquiring  Person to holders of equity  interests in such Acquiring Person or to
any  Person  with  whom  the  Acquiring  Person  has any  continuing  agreement,
arrangement or understanding  regarding the transferred Rights or (B) a transfer
which the Board of  Directors of the Company has  determined  is part of a plan,
arrangement  or  understanding  which has as a  primary  purpose  or effect  the
avoidance  of this Section 7(e) (a "Prior  Transferee")  or (iv) any  subsequent
transferee  receiving  transferred  Rights  from a Post  Transferee  or a  Prior
Transferee,  either  directly or through one or more  intermediate  transferees,
shall  become null and void  without  any  further  action and no holder of such
Rights shall have any rights  whatsoever  with  respect to such Rights,  whether
under any provision of this  Agreement or  otherwise.  The Company shall use all
reasonable  efforts  to insure  that the  provisions  of this  Section  7(e) and
Section 4(b) hereof are complied with, but shall have no liability to any holder
of Rights Certificates or to any other Person as a result of its failure to make
any determinations  with respect to an Acquiring Person or any of such Acquiring
Person's Affiliates, Associates or transferees hereunder.

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

      Section 8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES. All Rights
Certificates  surrendered  for the  purpose  of  exercise,  transfer,  split up,
combination  or exchange  shall,  if surrendered to the Company or to any of its
agents,  be delivered to the Rights Agent for  cancellation or in canceled form,
or, if surrendered  to the Rights Agent,  shall be canceled by it, and no Rights
Certificates  shall be issued in lieu thereof  except as expressly  permitted by
any of the provisions of this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement,  and the Rights Agent shall so cancel and
retire,  any other  Rights  Certificate  purchased  or  acquired  by the Company
otherwise  than upon the exercise  thereof.  The Rights Agent shall  deliver all
                                      -10-

<PAGE>


canceled Rights Certificates to the Company, or shall, at the written request of
the Company,  destroy such canceled Rights Certificates,  and in such case shall
deliver a certificate of destruction thereof to the Company.

      Section 9.  RESERVATION AND AVAILABILITY OF PREFERRED SHARES.

            (a) The  Company  covenants  and  agrees  that it will  use its best
efforts to cause to be reserved and kept  available  out of and to the extent of
its authorized and unissued  shares of Preferred  Stock not reserved for another
purpose  (and,  following  the  occurrence  of a  Triggering  Event,  out of its
authorized  and unissued  shares of Common Stock and/or other  securities),  the
number of Preferred  Shares (and,  following the  occurrence  of the  Triggering
Event,  Common Stock and/or other  securities) that will be sufficient to permit
the exercise in full of all outstanding Rights.

            (b) If the Company shall hereafter list any of its Preferred  Shares
on a national  securities  exchange,  then so long as the Preferred Shares (and,
following  the  occurrence  of a Triggering  Event,  Common  Shares and/or other
securities)  issuable and deliverable  upon exercise of the Rights may be listed
on such  exchange,  the Company  shall use its best  efforts to cause,  from and
after such time as the Rights become exercisable (but only to the extent that it
is reasonably likely that the Rights will be exercised), all shares reserved for
such issuance to be listed on such  exchange  upon  official  notice of issuance
upon such exercise.

            (c) The Company  shall use its best efforts to (i) file,  as soon as
practicable  following  the  earliest  date  after  the  first  occurrence  of a
Triggering Event in which the  consideration to be delivered by the Company upon
exercise of the Rights has been determined in accordance with Section  11(a)(iv)
hereof, or as soon as is required by law following the Distribution Date, as the
case may be, a  registration  statement  under the  Securities  Act of 1933,  as
amended (the "Securities Act"), with respect to the securities  purchasable upon
exercise  of the Rights on an  appropriate  form,  (ii) cause such  registration
statement to become effective as soon as practicable after such filing and (iii)
cause such registration  statement to remain effective (with a prospectus at all
times meeting the  requirements  of the Securities Act) until the earlier of (A)
the date as of which the Rights are no longer  exercisable  for such  securities
and (B) the date of  expiration  of the  Rights.  The  Company  may  temporarily
suspend, for a period not to exceed ninety (90) days after the date set forth in
clause (i) of the first sentence of this Section 9(c), the exercisability of the
Rights in order to prepare and file such registration statement and permit it to
become  effective.  Upon any such  suspension,  the Company shall issue a public
announcement  stating,  and notify the Rights Agent, that the  exercisability of
the Rights has been temporarily suspended,  as well as a public announcement and
notification  to the Rights Agent at such time as the suspension is no longer in
effect.  The Company will also take such action as may be appropriate  under, or
to ensure  compliance  with,  the  securities  or "blue sky" laws of the various
states in connection with the exercisability of the Rights.  Notwithstanding any
provision of this Agreement to the contrary, the Rights shall not be exercisable
in any  jurisdiction,  unless the requisite  qualification in such  jurisdiction
shall have been  obtained,  or an exemption  therefrom  shall be available,  and
until a registration statement has been declared effective.

            (d) The  Company  covenants  and  agrees  that it will take all such
action as may be necessary to ensure that all Preferred  Shares  delivered  upon

                                      -11-

<PAGE>

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 nonassessable shares.

            (e) The Company  further  covenants and agrees that it will pay when
due and payable any and all federal and state  transfer  taxes and charges which
may be payable in respect of the  original  issuance  or  delivery of the Rights
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 Rights  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
Rights 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 Rights Certificate at the time of surrender)
or until it has been established to the Company's  satisfaction that no such tax
is due.

      Section 10.  PREFERRED  SHARES RECORD DATE.  Each person in whose name any
certificate for a number of  one-thousandths of a Preferred Share is issued upon
the  exercise  of Rights  shall for all  purposes  be deemed to have  become the
holder  of  record  of  Preferred  Shares  represented   thereby  on,  and  such
certificate  shall  be  dated,  the  date  upon  which  the  Rights  Certificate
evidencing  such Rights was duly  surrendered  and payment of the Purchase Price
multiplied by the number of one-thousandths of a Preferred Share with respect to
which the Rights have been  exercised (and any  applicable  transfer  taxes) was
made;  provided,  however,  that if the date of such  surrender and payment is a
date upon which the Preferred  Shares  transfer books of the Company are closed,
such person shall be deemed to have become the record  holder of such shares on,
and such certificate  shall be dated, the next succeeding  Business Day on which
the  Preferred  Shares  transfer  books of the  Company  are open.  Prior to the
exercise of the Rights  evidenced  thereby,  the holder of a Rights  Certificate
shall not be  entitled to any rights of a holder of  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 and kind of shares or other  property
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 Common  Shares  payable in Common
Shares, (B) subdivide the outstanding Common Shares, (C) combine the outstanding
Common  Shares (by reverse stock split or  otherwise)  into a smaller  number of
Common   Shares,   or  (D)  issue  any  shares  of  its   capital   stock  in  a
reclassification  of the Common Shares (including any such  reclassification  in
connection with a consolidation or merger in which the Company is the continuing
or  surviving  corporation),  then,  in each such  event,  except  as  otherwise
provided in this Section  11(a) and Section 7(e) hereof:  (1) each of the Rights
outstanding  at the time of the record date for such  dividend or the  effective
date  of  such   subdivision,   combination   or   reclassification   shall   be
proportionately adjusted to that number of Rights (calculated to the nearest one
ten-thousandth  (1/10,000)  of a  Right)  equal  to a  fraction  (the  "Exchange
Ratio"),  the  numerator of which shall be the total number of Common  Shares or
                                      -12-

<PAGE>

shares of capital  stock issued in such  reclassification  of the Common  Shares
outstanding  immediately  following such time and the denominator of which shall
be the total number of Common Shares outstanding immediately prior to such time,
and the number of Rights that shall  thereafter  be issued with  respect to each
Common Share or share of such other capital stock that shall become  outstanding
thereafter prior to the Distribution  Date shall be equal to the total number of
outstanding  Rights  immediately  after such event (as adjusted pursuant to this
clause (1)) divided by the total number of  outstanding  Common Shares or shares
of such other capital  stock  immediately  after such event  (subject to further
adjustment pursuant to the provisions of this Agreement); (2) 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  shall be adjusted so
that the Purchase Price  thereafter  shall equal the result obtained by dividing
the  Purchase  Price in effect  immediately  prior to such time by the  Exchange
Ratio;  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 such Right; and
(3) the number of Common Shares or shares of such other  capital stock  issuable
upon the exercise of each Right shall remain  unchanged  immediately  after such
event, but, in the event of a reclassification, the kind of shares issuable upon
the  exercise of each Right  immediately  after such  reclassification  shall be
adjusted  to be the kind of shares of such other  capital  stock  issued in such
reclassification,  rather than Common  Shares.  If an event  occurs  which would
require an  adjustment  under both this Section  11(a)(i) and Section  11(a)(ii)
hereof,  the  adjustment  provided  for in this  Section  11(a)(i)  shall  be in
addition  to, and shall be made prior to, any  adjustment  required  pursuant to
Section 11(a)(ii) hereof.

                  (ii) Subject to Section 24 of this  Agreement,  in the event a
Triggering  Event shall have occurred,  then promptly  following such Triggering
Event,  proper provision shall be made so that each holder of a Right, except as
provided in Section 7(e) hereof,  shall thereafter have the right to receive for
each Right, upon exercise thereof in accordance with the terms of this Agreement
and payment of the  then-current  Total Exercise  Price,  in lieu of a number of
one-thousandths  of a  Preferred  Share,  such  number of  Common  Shares of the
Company as shall  equal the result  obtained  by  multiplying  the  then-current
Purchase Price by the then number of  one-thousandths  of a Preferred  Share for
which  a  Right  was  exercisable  (or  would  have  been   exercisable  if  the
Distribution  Date had occurred)  immediately prior to the first occurrence of a
Triggering  Event,  and  dividing  that  product by 50% of the current per share
market price (determined  pursuant to Section 11(d) hereof) for Common Shares on
the date of  occurrence  of the  Triggering  Event (such  number of shares being
hereinafter referred to as the "Adjustment Shares").

                 (iii) The right to buy Common Shares of the Company pursuant to
Section  11(a)(ii)  hereof shall not arise as a result of any Person becoming an
Acquiring Person through an acquisition of Common Shares pursuant to a Permitted
Offer.

                  (iv) In lieu of  issuing  Common  Shares  in  accordance  with
Section 11(a)(ii) hereof, the Company may, if the Board of Directors  determines
that such action is necessary or appropriate and not contrary to the interest of
holders of Rights (and,  in the event that the number of Common Shares which are
authorized by the Company's  Certificate of Incorporation but not outstanding or
reserved for issuance  for purposes  other than upon  exercise of the Rights are
not sufficient to permit the exercise in full of the Rights, or if any necessary

                                      -13-

<PAGE>

regulatory approval for such issuance has not been obtained by the Company,  the
Company  shall):  (A) determine the excess of (1) the value of the Common Shares
issuable  upon  the  exercise  of a Right  (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 exercise of
the Rights,  (1) cash, (2) a reduction in the Purchase  Price,  (3) other equity
securities of the Company  (including,  without  limitation,  shares or units of
shares of any series of  preferred  stock  which the Board of  Directors  of the
Company has deemed to have the same value as Common Shares (such shares or units
of shares of preferred  stock are herein called  "common  stock  equivalents")),
except to the extent that the Company has not obtained any necessary shareholder
or regulatory  approval for such issuance,  (4) debt  securities of the Company,
except to the extent that the Company has not obtained any necessary shareholder
or  regulatory  approval  for  such  issuance,  (5)  other  assets  or  (6)  any
combination  of the  foregoing,  having an aggregate  value equal to the Current
Value,  where such aggregate value has been determined by the Board of Directors
of the  Company  based upon the  advice of a  nationally  recognized  investment
banking  firm  selected  by the Board of  Directors  of the  Company;  PROVIDED,
HOWEVER,  if the Company shall not have made adequate provision to deliver value
pursuant to clause (B) above within thirty (30) days  following the later of (x)
the  first  occurrence  of a  Triggering  Event  and (y) the date on  which  the
Company's  right of  redemption  pursuant to Section 23(a) expires (the later of
(x) and (y) being referred to herein as the "Section  11(a)(ii)  Trigger Date"),
then the Company shall be obligated to deliver,  upon the surrender for exercise
of a Right and without  requiring  payment of the Purchase Price,  Common Shares
(to the  extent  available),  except  to the  extent  that the  Company  has not
obtained any necessary shareholder or regulatory approval for such issuance, and
then, if necessary, cash, which shares and/or 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  Common  Shares  could be
authorized  for  issuance  upon  exercise  in full  of the  Rights  or that  any
necessary  regulatory  approval for such issuance  will be obtained,  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  shareholder  approval for the  authorization  of such
additional  shares or take  action  to obtain  such  regulatory  approval  (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)(iv),  the  Company  (x) shall
provide,  subject to Section 7(e) 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,  to take any action to obtain any required
regulatory  approval 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  issue a public  announcement
stating that the exercisability of the Rights has been temporarily suspended, as
well as a public  announcement  at such time as the  suspension  is no longer in
effect. For purposes of this Section  11(a)(iv),  the value of the Common Shares
shall be the current per share market price (as  determined  pursuant to Section
11(d) 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,  at any time after the date of this
Agreement,  fix a record date for the issuance of rights, options or warrants to
all  holders  of Common  Shares or of any class or series of  Equivalent  Shares
entitling such holders (for a period  expiring  within  forty-five (45) calender
                                      -14-

days after such  record  date) to  subscribe  for or purchase  Common  Shares or
Equivalent  Shares or  securities  convertible  into Common Shares or Equivalent
Shares at a price  per  share (or  having a  conversion  price per  share,  if a
security convertible into Common Shares or Equivalent Shares) less than the then
current per share market  price of the Common  Shares or  Equivalent  Shares (as
defined in Section  11(d)) on such record  date,  then,  in each such case,  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 Common Shares and
Equivalent  Shares (if any)  outstanding on such record date, plus the number of
Common  Shares or  Equivalent  Shares,  as the case may be, which the  aggregate
offering price of the total number of Common Shares or Equivalent Shares, as the
case may be, 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 Common Shares
and Equivalent  Shares (if any) outstanding on such record date, plus the number
of  additional  Common Shares or  Equivalent  Shares,  as the case may be, to be
offered for  subscription or purchase (or into which the convertible  securities
so to be offered are initially convertible). In case such subscription price may
be paid in a  consideration  part or all of which  shall be in a form other than
cash,  the value of such  consideration  shall be as determined in good faith by
the Board of Directors of the Company, whose determination shall be described in
a statement filed with the Rights Agent and shall be binding on the Rights Agent
and the holders of the Rights.  Common Shares and Equivalent  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,  at any time after the date of this
Agreement,  fix a record date for the making of a distribution to all holders of
the Common Shares or of any class or series of Equivalent  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,  if any, or a dividend
payable in Common Shares) or subscription rights, options or warrants (excluding
those referred to in Section 11(b)), then, in each such case, the Purchase Price
to be in effect after such record date shall be  determined by  multiplying  the
Purchase  Price in effect  immediately  prior to such record date by a fraction,
the numerator of which shall be the current market price (as determined pursuant
to Section 11(d) hereof) of a Common Share or an Equivalent Share 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 cash,  assets or evidences of
indebtedness  so to be  distributed or of such  subscription  rights or warrants
applicable  to a Common Share or Equivalent  Share,  as the case may be, and the
denominator of which shall be such current market price (as determined  pursuant
to Section 11(d)  hereof) of a Common Share or  Equivalent  Share on such record
date. 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 be adjusted to be the Purchase Price which would have been in effect
if such record date had not been fixed.

            (d)  For  the  purpose  of any  computation  hereunder,  other  than
computations made pursuant to Section  11(a)(iv) hereof,  the "current per share
market  price" of any  security (a  "Security"  for the purpose of this  Section
11(d)) on any date shall be deemed to be the average of the daily closing prices
per share of such Security for the thirty (30) consecutive Trading Days (as such
term is hereinafter defined) immediately prior to such date, and for purposes of
computations made pursuant to Section  11(a)(iv) hereof,  the "current per share
market  price" of any  Security on any date shall be deemed to be the average of
the daily closing prices per share of such Security for the ten (10) consecutive
Trading Days  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 (i)
a dividend or distribution  on such Security  payable in shares of such Security
or securities convertible into such shares or (ii) any subdivision,  combination
or  reclassification  of such  Security,  and  prior  to the  expiration  of the
requisite  thirty  (30)  Trading Day or ten (10)  Trading Day period,  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 sale  price or, if such last sale
price is not  reported,  the average of the high bid and low asked prices in the
over-the-counter  market, as reported by the National  Association of Securities
Dealers,  Inc. Automated Quotations  ("Nasdaq") System or such other system then
in use,  or,  if on any  such  date  the  Security  is not  quoted  by any  such
organization,  the average of the closing bid and asked prices as furnished by a
professional  market maker making a market in the Security selected by the Board
of  Directors  of the  Company.  If on any such date no market maker is making a
market  in the  Common  Shares,  the fair  value of such  shares on such date as
determined in good faith by the Board of Directors of the Company shall be used.
The  term  "Trading  Day"  shall  mean a day on  which  the  principal  national
securities  exchange  on which the  Security is listed or admitted to trading is
open for the  transaction  of  business  or, if the  Security  is not  listed or
admitted to trading on any national securities  exchange, a Business Day. If the
Common Shares are not 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  and  shall be  conclusive  for all
purposes.

            (e) Anything herein to the contrary  notwithstanding,  no adjustment
in the Purchase Price shall be required unless such adjustment  would require an
increase or decrease of at least 1% in the Purchase  Price;  PROVIDED,  HOWEVER,
that any  adjustments  which by reason of this Section 11(e) are not required to
be made  shall be carried  forward  and taken  into  account  in any  subsequent
adjustment.  All calculations under this Section 11 shall be made to the nearest
cent or to the nearest  ten-thousandth  of a Common  Share or other share or one
hundred-thousandth of a Preferred Share, as the case may be. Notwithstanding the
first sentence of this Section 11(e), any adjustment required by this Section 11

                                      -16-

<PAGE>

shall be made no later than the  earlier of (i) three (3) years from the date of
the transaction which requires such adjustment or (ii) the Expiration Date.

            (f) If as a result of an  adjustment  made pursuant to Section 11(a)
or 13(a)  hereof,  the holder of any Right  thereafter  exercised  shall  become
entitled to receive any shares of capital  stock  other than  Preferred  Shares,
thereafter  the number of such other shares so  receivable  upon exercise of any
Right  and if  required,  the  Purchase  Price  thereof,  shall  be  subject  to
adjustment  from time to time in a manner and on terms as nearly  equivalent  as
practicable  to the  provisions  with respect to the Common Shares  contained in
Sections  11(a),  (b),  (c),  (e),  (h),  (i),  (j),  (k),  (l) and (m), and the
provisions of Sections 7, 9, 10, 13 and 14 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-thousandths  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 Section 11(b), 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 Preferred Shares  (calculated to
the nearest one  hundred-thousandth  of a share) obtained by (i) multiplying (x)
the number of  Preferred  Shares  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 as a result of the  calculations  made in Section  11(b) to
adjust the number of Rights, in substitution for any adjustment in the number of
Preferred Shares  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-thousandths  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  hundred-thousandth)  obtained by dividing
the Purchase  Price in effect  immediately  prior to  adjustment of the Purchase
Price by the  Purchase  Price in  effect  immediately  after  adjustment  of the
Purchase Price. The Company shall make a public  announcement of its election to
adjust the number of Rights, indicating the record date for the adjustment, and,
if known at the time, the amount of the adjustment to be made.  This record date
may be the date on which the Purchase  Price is adjusted or any day  thereafter,
but, if the Rights  Certificates  have been  issued,  shall be at least ten (10)
days later than the date of the public announcement. If Rights Certificates have
been  issued,  upon each  adjustment  of the number of Rights  pursuant  to this
Section  11(i),  the Company  shall,  as promptly  as  practicable,  cause to be
distributed  to holders of record of Rights  Certificates  on such  record  date
Rights  Certificates  evidencing,  subject to Section 14 hereof,  the additional
Rights to which such holders  shall be entitled as a result of such  adjustment,
or, at the option of the Company,  shall cause to be distributed to such holders

                                      -17-

<PAGE>

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

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

            (k) Before taking any action that would cause an adjustment reducing
the  Purchase  Price  below the par or stated  value,  if any,  of the number of
one-thousandths  of a Preferred Share 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 as
fully  paid  and  nonassessable  shares  such  number  of  one-thousandths  of a
Preferred Share 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 number of  one-thousandths  of a Preferred  Share and other capital stock or
securities  of the Company,  if any,  issuable upon such exercise over and above
the number of  one-thousandths  of a Preferred  Share and other capital stock or
securities of the Company,  if any,  issuable upon such exercise on the basis of
the Purchase Price in effect prior to such adjustment;  PROVIDED,  HOWEVER, that
the  Company  shall  deliver  to such  holder a due  bill or  other  appropriate
instrument  evidencing  such holder's  right to receive such  additional  shares
(fractional  or  otherwise)  upon the  occurrence  of the event  requiring  such
adjustment.

            (m)  Anything in this  Section 11 to the  contrary  notwithstanding,
prior to the  Distribution  Date,  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 or Common Shares,  (ii) issuance wholly for cash of
any  Preferred or Common  Shares at less than the current  market  price,  (iii)
issuance  wholly for cash of Preferred or Common Shares or  securities  which by
their terms are convertible into or exchangeable for Preferred or Common Shares,
(iv) stock dividends or (v) issuance of rights,  options or warrants referred to
in this Section 11, hereafter made by the Company to holders of its Preferred or
Common Shares shall not be taxable to such shareholders.

            (n) The Company  covenants and agrees that it shall not, at any time
after the Distribution  Date,  effect or permit to occur any Triggering Event or
Section 13 Event, if (i) at the time or immediately  after such Triggering Event


                                      -18-


<PAGE>
or Section 13 Event  there are any  rights,  warrants  or other  instruments  or
securities  outstanding  or  agreements  in  effect  which  would  substantially
diminish or  otherwise  eliminate  the  benefits  intended to be afforded by the
Rights or (ii) prior to,  simultaneously  with or immediately after such Section
13 Event, the shareholders of the Person who constitutes,  or would  constitute,
the "Principal Party" for purposes of Section 13(b) hereof shall have received a
distribution of Rights  previously owned by such Person or any of its Affiliates
and Associates.

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

            (p) Anything in this Agreement to the contrary  notwithstanding,  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 (by reverse stock split or otherwise) 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),  then,  in each such  event,  except  as  otherwise
provided in this  Section 11 and  Section  7(e)  hereof:  (1) each of the Rights
outstanding  at the time of the record date for such  dividend or the  effective
date  of  such   subdivision,   combination   or   reclassification   shall   be
proportionately adjusted to that number of Rights (calculated to the nearest one
ten-thousandth  (1/10,000)  of a  Right)  equal  to a  fraction  (the  "Exchange
Fraction"), the numerator of which shall be the total number of Preferred Shares
or shares of capital  stock  issued in such  reclassification  of the  Preferred
Shares outstanding  immediately following such time and the denominator of which
shall be the total number of Preferred Shares  outstanding  immediately prior to
such time, and the number of Rights that shall thereafter be issued with respect
to each Common Share or share of other  capital  stock that shall be issued in a
reclassification  of the Common Shares prior to the  Distribution  Date shall be
equal to the total number of outstanding Rights immediately after such event (as
adjusted pursuant to this clause (1)) divided by the total number of outstanding
Common Shares or shares of such other capital stock immediately after such event
(subject to further  adjustment  pursuant to the provisions of this  Agreement);
(2) 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  shall be adjusted so that the Purchase Price  thereafter shall
equal the result  obtained by dividing the Purchase Price in effect  immediately
prior to such time by the Exchange Fraction; 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 such  Right;  and  (3) the  number  of  one-thousandths  of a
Preferred  Share or share of such other capital stock issuable upon the exercise
of each Right shall remain unchanged  immediately  after such event, but, in the
event of a  reclassification,  the kind of shares  issuable upon the exercise of
each Right immediately after such  reclassification  shall be adjusted to be the
kind of shares of such  other  capital  stock  issued in such  reclassification,
rather than Preferred Shares.

      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 suchadjustment,  (b) file with
                                      -19-

<PAGE>

the Rights Agent and with each transfer agent for the Preferred Shares a copy of
such certificate and (c) mail a brief summary thereof to each holder of a Rights
Certificate in accordance with Section 26 hereof.  Notwithstanding the foregoing
sentence,  the  failure of the Company to make such  certification  or give such
notice shall not affect the validity of such  adjustment  or the force or effect
of the  requirement  for  such  adjustment.  The  Rights  Agent  shall  be fully
protected in relying on any such  certificate  and on any  adjustment  contained
therein and shall not be deemed to have knowledge of such adjustment  unless and
until it shall have received such certificate.

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

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

                   (i) the Company  shall  consolidate  with,  or merge with and
into,  any other Person (other than a Subsidiary of the Company in a transaction
the principal  purpose of which is to change the state of  incorporation  of the
Company or which complies with Section 11(o) hereof);

                  (ii) any Person  (other than a Subsidiary  of the Company in a
transaction that complies with Section 11(o) hereof) shall  consolidate with the
Company,  or  merge  with  and into the  Company  and the  Company  shall be the
continuing or surviving corporation of such consolidation or merger; or

                  (iii) the Company shall sell or otherwise  transfer (or one or
more of its  Subsidiaries  shall  sell or  otherwise  transfer),  in one or more
transactions,  assets or earning power  aggregating 50% or more of the assets or
earning  power of the  Company  and its  Subsidiaries  (taken as a whole) to any
other  Person or Persons  (other  than the  Company or one or more of its wholly
owned  Subsidiaries  in one or more  transactions,  each of which  complies with
Section 11(o) hereof),

                        then, and  in  each such case, proper provision shall be
made so that

                        (A) each holder of a Right (except as otherwise provided
herein) shall thereafter have the right to receive, upon the exercise thereof in
accordance with the terms of this Agreement,  such number of validly  authorized
and issued,  fully paid and  nonassessable  Common Shares of the Principal Party
(as  hereinafter  defined),  free of any  liens,  encumbrances,  rights of first
refusal or other adverse claims, as shall be equal to the result obtained by (1)
multiplying the then current Purchase Price by the number of  one-thousandths of
a Preferred  Share for which a Right was  exercisable  immediately  prior to the
first  occurrence of a Section 13 Event (or, if a Triggering  Event has occurred
prior to the first  occurrence of a Section 13 Event,  multiplying the number of
such  one-thousandths  of a  Preferred  Share for which a Right was  exercisable
immediately  prior to the first occurrence of a Triggering Event by the Purchase
Price in effect  immediately  prior to such first  occurrence)  and (2) dividing
that product (which, following the first occurrence of a Section 13 Event, shall
be referred to as the "Total Exercise Price" for each Right and for all purposes
of this  Agreement)  by 50% of the current per share  market  price  (determined
pursuant to Section 11(d) hereof) of the Common Shares of such  Principal  Party
on the date of consummation of such Section 13 Event;

                                      -20-

<PAGE>

                        (B)   such  Principal  Party  shall thereafter be liable
for, and shall assume,  by virtue of such Section 13 Event,  all the obligations
and duties of the Company pursuant to this Agreement;

                        (C)   the  term "Company" shall thereafter be  deemed to
refer  to  such  Principal  Party,  it  being  specifically  intended  that  the
provisions  of  Section  11 hereof  shall  apply  only to such  Principal  Party
following the first occurrence of a Section 13 Event;

                        (D)   such  Principal  Party   shall  take  such   steps
(including,  but not limited to, the  reservation of a sufficient  number of its
Common Shares) in connection with the  consummation  of any such  transaction as
may be  necessary  to assure that the  provisions  hereof  shall  thereafter  be
applicable,  as nearly as  reasonably  may be, in relation to its Common  Shares
thereafter deliverable upon the exercise of the Rights.

            (b)  "Principal  Party" shall mean,  in the case of any  transaction
described in clause (i), (ii) or (iii) of Section 13(a), the Person or Acquiring
Person  referred to therein (or such Person's or Acquiring  Person's  successor,
including,  if  applicable,  the Company,  if it is the surviving  corporation),
PROVIDED,  HOWEVER,  that in any such  case,  (i) if such  Person is a direct or
indirect  Subsidiary of another  Person,  "Principal  Party" shall refer to such
other  Person  and  (ii)  in case  such  Person  is a  Subsidiary,  directly  or
indirectly,  of more than one Person, "Principal Party" shall refer to whichever
of such Persons is the issuer of the Common Shares having the greatest aggregate
value,  and PROVIDED,  FURTHER,  that for purposes of transactions  described in
clause (iii) hereof,  "Principal Party" shall refer to that Person receiving the
greatest  portion of the assets or earning  power  transferred  pursuant to such
transaction or transactions.

            (c) If, for any reason,  the Rights  cannot be exercised  for Common
Shares of such Principal Party as provided in Section 13(a), then each holder of
Rights shall have the right to exchange its Rights for cash from such  Principal
Party in an amount equal to the number of Common Shares that it would  otherwise
be entitled to purchase  times 50% of the  current per share  market  price,  as
determined  pursuant to Section  11(d)  hereof,  of such  Common  Shares of such
Principal Party. If, for any reason, the foregoing formulation cannot be applied
to determine  the cash amount into which the Rights are  exchangeable,  then the
Board of Directors,  based upon the advice of one or more nationally  recognized
investment  banking firms, and based upon the total value of the Company,  shall
determine  such amount  reasonably and with good faith to the holders of Rights.
Any such determination shall be final and binding on the Rights Agent.

            (d)  Notwithstanding  anything in this  Agreement  to the  contrary,
Section 13 shall not be applicable to a transaction described in clauses (i) and
(ii) of Section 13(a) if: (i) such  transaction is consummated  with a Person or
Persons  who  acquired  Common  Shares  pursuant  to a  Permitted  Offer  (or  a
wholly-owned Subsidiary of any such Person or Persons); (ii) the price per share
of Common  Shares  offered  in such  transaction  is not less than the price per
share of Common  Shares paid to all holders of Common  Shares  whose shares were
purchased  pursuant to such Permitted Offer; and (iii) the form of consideration
being  offered  to the  remaining  holders  of Common  Shares  pursuant  to such


                                      -21-


<PAGE>


transaction is the same form as the form of consideration  paid pursuant to such
Permitted Offer. Upon consummation of any such transaction  contemplated by this
Section 13(d), all Rights hereunder shall expire.

            (e) The Company shall not consummate any Section 13 Event unless the
Principal Party shall have a sufficient  number of authorized Common Shares that
have not been issued or reserved  for issuance to permit the exercise in full of
the Rights in  accordance  with this  Section 13 and unless  prior  thereto  the
Company and such issuer shall have  executed and delivered to the Rights Agent a
supplemental   agreement  confirming  that  such  Principal  Party  shall,  upon
consummation of such Section 13 Event,  assume this Agreement in accordance with
Sections  13(a) and (b) hereof,  that all rights of first  refusal or preemptive
rights in respect of the issuance of Common Shares of such Principal  Party upon
exercise  of  outstanding  Rights  have been  waived,  that there are no 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 and that such transaction shall not result in a default by such Principal
Party under this Agreement,  and further  providing that, as soon as practicable
after the date of such Section 13 Event, such Principal Party will:

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

                  (ii) use its best efforts to list (or continue the listing of)
the Rights  and the  securities  purchasable  upon  exercise  of the Rights on a
national  securities  exchange  or to  meet  the  eligibility  requirements  for
quotation on the Nasdaq National Market; and

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

                  In the  event  that at any  time  after  the  occurrence  of a
Triggering  Event some or all of the Rights shall not have been exercised at the
time of a  transaction  described  in this Section 13, the Rights which have not
theretofore  been  exercised  shall  thereafter  be  exercisable  in the  manner
described in Section  13(a)  (without  taking into account any prior  adjustment
required by Section 11(a)(ii)).

            (f) 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 Rights  Certificates which evidence  fractional Rights. In lieu
of such fractional Rights,  there shall be paid to the registered holders of the
Rights  Certificates with regard to which such fractional Rights would otherwise
be issuable,  an amount in cash equal to the same fraction of the current market
value of a whole  Right.  For the purposes of this  Section  14(a),  the current
market  value of a whole Right shall be the closing  price of the Rights for the
Trading Day immediately  prior to the date on which such fractional Rights would
have been otherwise  issuable,  as determined pursuant to the second sentence of
Section 11(d) hereof.

            (b)  The  Company  shall  not be  required  to  issue  fractions  of
Preferred  Shares  (other than  fractions  that are  integral  multiples  of one
one-thousandth  of a  Preferred  Share)  upon  exercise  of  the  Rights  or  to
distribute  certificates which evidence fractional  Preferred Shares (other than
fractions  that are  integral  multiples  of one  one-thousandth  of a Preferred
Share). In lieu of fractional  Preferred Shares that are not integral  multiples
of one  one-thousandth  of a  Preferred  Share,  the  Company  shall  pay to the
registered holders of Rights  Certificates at the time such Rights are exercised
as herein  provided an amount in cash equal to the same  fraction of the current
market value of a Common Share.  For purposes of this Section 14(b), the current
market value of a Common Share shall be the closing  price of a Common Share (as
determined  pursuant  to the second  sentence of Section  11(d)  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  his or her right to  receive  any  fractional  Rights or any  fractional
shares upon exercise of a Right.

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

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

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

                                      -23-


<PAGE>
            (b)  after  the  Distribution  Date,  the  Rights  Certificates  are
transferable  only on the registry  books of the Rights Agent if  surrendered at
the  principal  office  or  offices  of the  Rights  Agent  designated  for such
purposes,  duly endorsed or accompanied  by a proper  instrument of transfer and
with the appropriate forms and certificates fully executed; and

            (c) subject to Sections  6(a) and 7(f)  hereof,  the Company and the
Rights Agent may deem and treat the person in whose name the Rights  Certificate
(or, prior to the Distribution  Date, the associated Common Shares  certificate)
is registered as the absolute owner thereof and of the Rights evidenced  thereby
(notwithstanding   any   notations   of  ownership  or  writing  on  the  Rights
Certificates or the associated  Common 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. RIGHTS CERTIFICATE HOLDER NOT DEEMED A SHAREHOLDER. No holder,
as such, of any Rights  Certificate shall be entitled to vote, receive dividends
or be deemed for any  purpose  the holder of the  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
Rights  Certificate  be  construed  to  confer  upon the  holder  of any  Rights
Certificate,  as such,  any of the rights of a shareholder of the Company or any
right to vote for the  election of  directors  or upon any matter  submitted  to
shareholders  at any  meeting  thereof,  or to give or  withhold  consent to any
corporate  action,  or to receive notice of meetings or other actions  affecting
shareholders  (except as provided in Section 25 hereof), or to receive dividends
or subscription  rights,  or otherwise,  until the Right or Rights  evidenced by
such  Rights  Certificate  shall  have been  exercised  in  accordance  with the
provisions hereof.

      Section 18.  CONCERNING THE RIGHTS AGENT.

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

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


                                      -24-

certificate,  statement or other paper or document  believed by it to be genuine
and to be signed,  executed and, where necessary,  verified or acknowledged,  by
the proper  Person or Persons,  or  otherwise  upon the advice of counsel as set
forth in Section 20 hereof.

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

            (a) Any  corporation  into which the Rights  Agent or any  successor
Rights  Agent  may be  merged  or  with  which  it may be  consolidated,  or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor  Rights Agent shall be a party,  or any corpora tion succeeding
to the  corporate  trust  business of the Rights Agent or any  successor  Rights
Agent,  shall be the successor to the Rights Agent under this Agreement  without
the  execution  or filing of any paper or any  further act on the part of any of
the parties hereto;  provided,  however, that such corporation would be eligible
for  appointment as a successor  Rights Agent under the provisions of Section 21
hereof.  In case at the time such  successor  Rights Agent shall  succeed to the
agency created by this Agreement, any of the Rights Certificates shall have been
countersigned  but not delivered,  any such successor Rights Agent may adopt the
countersignature  of the  predecessor  Rights  Agent  and  deliver  such  Rights
Certificates  so  countersigned;  and in  case at that  time  any of the  Rights
Certificates shall not have been  countersigned,  any successor Rights Agent may
countersign  such  Rights  Certificates  either  in the name of the  predecessor
Rights Agent or in the name of the successor Rights Agent; and in all such cases
such  Rights  Certificates  shall  have the full  force  provided  in the Rights
Certificates and in this Agreement.

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

      Section 20. DUTIES OF RIGHTS AGENT. The Rights Agent undertakes the duties
and  obligations  imposed  by  this  Agreement  upon  the  following  terms  and
conditions,  by all of which the Company and the holders of Rights 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
(including,  without  limitation,  the identity of any Acquiring  Person and the
determination  of "current per share market  price") 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 Chief Financial Officer,  the
Secretary or any Assistant  Secretary of the Company and delivered to the Rights

                                      -25-

<PAGE>

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

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

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

            (e) The  Rights  Agent  shall  not be under  any  responsibility  in
respect of the validity of this  Agreement or the execution and delivery  hereof
(except  the due  execution  hereof by the  Rights  Agent) or in  respect of the
validity or execution  of any Rights  Certificate  (except its  countersignature
thereof);  nor shall it be  responsible  for any  breach by the  Company  of any
covenant or condition  contained in this Agreement or in any Rights Certificate;
nor shall it be responsible for any change in the  exercisability  of the Rights
or any adjustment in the terms of the Rights  (including  the manner,  method or
amount  thereof)  provided  for  in  Sections  3,  11,  13,  23 or  24,  or  the
ascertaining  of the  existence  of facts that would  require any such change or
adjustment  (except with  respect to the exercise of Rights  evidenced by Rights
Certificates  after  receipt  by the  Rights  Agent of a  certificate  furnished
pursuant to Section 12 describing  such change or  adjustment);  nor shall it by
any act  hereunder  be deemed to make any  representation  or warranty as to the
authorization  or reservation of any Preferred  Shares to be issued  pursuant to
this Agreement or any Rights  Certificate or as to whether any Preferred  Shares
will,  when  issued,   be  validly   authorized  and  issued,   fully  paid  and
nonassessable.

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

            (g) The Rights  Agent is hereby  authorized  and  directed to accept
instructions  with respect to the  performance of its duties  hereunder from any
one of the Chairman of the Board,  the Chief Executive  Officer,  the President,
any Vice President,  the Chief Financial Officer, the Secretary or any Assistant
Secretary  of the  Company,  and  to  apply  to  such  officers  for  advice  or
instructions in connection  with its duties,  and it shall not be liable for any
action taken or suffered by it in good faith in accordance with  instructions of
any  such  officer  or  for  any  delay  in  acting  while   waiting  for  those
instructions.  Any application by the Rights Agent for written instructions from
the  Company  may, at the option of the Rights  Agent,  set forth in writing any
action  proposed  to be taken or omitted by the Rights  Agent  under this Rights
Agreement  and the date on and/or after which such action shall be taken or such
omission shall be effective. The Rights Agent shall not be liable for any action
taken by, or  omission  of,  the  Rights  Agent in  accordance  with a  proposal
included  in any  such  application  on or  after  the  date  specified  in such
application  (which date shall not be less than five (5) Business Days after the
date any officer of the Company actually receives such  application,  unless any
such officer shall have  consented in writing to an earlier date) unless,  prior
to taking any such action (or the  effective  date in the case of an  omission),
                                      -26-

<PAGE>

the Rights Agent shall have received  written  instructions  in response to such
application specifying the action to be taken or omitted.

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

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

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

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

      Section 21.  CHANGE OF RIGHTS  AGENT.  The Rights  Agent or any  successor
Rights Agent may resign and be discharged  from its duties under this  Agreement
upon  thirty  (30) days'  notice in writing  mailed to the  Company  and to each
transfer  agent of the  Preferred  Shares and the Common Shares by registered or
certified  mail,  and to the holders of the Rights  Certificates  by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty (30) days'  notice in writing,  mailed to the Rights  Agent or  successor
Rights Agent,  as the case may be, and to each  transfer  agent of the Preferred
Shares and the Common Shares by registered or certified mail, and to the holders
of the Rights Certificates by first-class mail. If the Rights Agent shall resign
or be removed or shall otherwise become  incapable of acting,  the Company shall
appoint a successor to the Rights Agent.  If the Company shall fail to make such
appointment  within a period of thirty  (30) days  after  giving  notice of such
removal  or  after  it has been  notified  in  writing  of such  resignation  or
incapacity by the resigning or incapacitated  Rights Agent or by the holder of a
Rights  Certificate  (who  shall,  with such  notice,  submit  his or her Rights
Certificate  for inspection by the Company),  then the registered  holder of any
Rights  Certificate  may apply to any court of  competent  jurisdiction  for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court,  shall be a  corporation  organized and doing
business  under the laws of the  United  States  or of any  state of the  United
States,  in good  standing,  which is  authorized  under  such laws to  exercise

                                      -27-


<PAGE>

corporate trust or shareholder  services 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. After appointment,  the successor Rights Agent shall be vested with the
same powers,  rights,  duties and  responsibilities as if it had been originally
named as Rights Agent without  further act or deed; but the  predecessor  Rights
Agent shall deliver and transfer to the  successor  Rights Agent any property at
the time held by it  hereunder,  and execute and deliver any further  assurance,
conveyance,  act or deed necessary for the purpose. Not later than the effective
date of any such  appointment,  the Company shall file notice thereof in writing
with the  predecessor  Rights  Agent and each  transfer  agent of the  Preferred
Shares  and the  Common  Shares,  and mail a notice  thereof  in  writing to the
registered  holders  of the  Rights  Certificates.  Failure  to give any  notice
provided  for in this  Section 21,  however,  or any defect  therein,  shall not
affect the  legality  or validity  of the  resignation  or removal of the Rights
Agent or the appointment of the successor Rights Agent, as the case may be.

      Section 22. ISSUANCE OF NEW RIGHTS  CERTIFICATES.  Notwithstanding  any of
the provisions of this  Agreement or of the Rights to the contrary,  the Company
may, at its option, issue new Rights Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the  Purchase  Price  and the  number  or kind or  class of  shares  or other
securities  or  property  purchasable  under  the  Rights  Certificates  made in
accordance  with the provisions of this  Agreement.  In addition,  in connection
with the issuance or sale of Common Shares following the  Distribution  Date and
prior to the redemption or expiration of the Rights, the Company (a) shall, with
respect to Common  Shares so issued or sold  pursuant  to the  exercise of stock
options  or  under  any  employee  plan or  arrangement  or upon  the  exercise,
conversion or exchange of the convertible subordinated debentures of the Company
outstanding  at the date hereof or upon the exercise,  conversion or exchange of
securities  hereinafter issued by the Company and (b) may, in any other case, if
deemed necessary or appropriate by the Board of Directors of the Company,  issue
Rights Certificates  representing the appropriate number of Rights in connection
with  such  issuance  or  sale;  PROVIDED,  HOWEVER,  that  (i) no  such  Rights
Certificate  shall be issued and this sentence  shall be null and void AB INITIO
if, and to the extent  that,  such  issuance  or this  sentence  would  create a
significant  risk of or result  in  material  adverse  tax  consequences  to the
Company or the Person to whom such Rights  Certificate  would be issued or would
create a significant  risk of or result in such  options' or employee  plans' or
arrangements'  failing to qualify for otherwise  available special tax treatment
and (ii) no such Rights  Certificate shall be issued if, and to the extent that,
appropriate  adjustment  shall  otherwise have been made in lieu of the issuance
thereof.

      Section 23.  REDEMPTION.

            (a)   The Company may,  at  its option and with the  approval of the
Board of Directors, at any time prior to the Close of Business on the earlier of
(i) the tenth day  following the Shares  Acquisition  Date or such later date as
may be determined by action of a majority of Continuing Directors then in office
and publicly  announced by the Company or (ii) the Final Expiration Date, redeem
all but not less than all the then  outstanding  Rights at a redemption price of
$0.01 per Right,  appropriately  adjusted  to  reflect  any stock  split,  stock
dividend or similar transaction occurring after the date hereof (such redemption
price being herein referred to as the  "Redemption  Price") and the Company may,
at its option,  pay the  Redemption  Price either in Common Shares (based on the
current per share market price thereof (as determined  pursuant to Section 11(d)

                                      -28-

<PAGE>

hereof) at the time of redemption) or cash. Such redemption of the Rights by the
Company  may be made  effective  at such  time,  on such  basis  and  with  such
conditions  as the Board of  Directors  in its sole  discretion  may  establish;
PROVIDED,  HOWEVER,  if  the  Board  of  Directors  of  the  Company  authorizes
redemption  of the  Rights on or after the time a Person  becomes  an  Acquiring
Person,  then  there  must be  Continuing  Directors  then in  office  and  such
authorization  shall require the  concurrence  of a majority of such  Continuing
Directors.
            (b)  Immediately  upon the action of the Board of  Directors  of the
Company ordering the redemption of the Rights, evidence of which shall have been
filed with the Rights  Agent,  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
effect the validity of such redemption. Within ten (10) days after the action of
the Board of Directors  ordering the redemption of the Rights, the Company shall
give notice of such  redemption  to the Rights Agent and the holders of the then
outstanding  Rights by  mailing  such  notice to all such  holders at their last
addresses as they appear upon the  registry  books of the 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. Each such notice of
redemption  will state the method by which the payment of the  Redemption  Price
will be made.  Neither the Company nor any of its  Affiliates or Associates  may
redeem, acquire or purchase for value any Rights at any time in any manner other
than that specifically set forth in this Section 23 or in Section 24 hereof, and
other  than in  connection  with the  purchase  of  Common  Shares  prior to the
Distribution Date.

      Section 24.  EXCHANGE.

            (a) Subject to applicable laws,  rules and regulations,  and subject
to subsection (c) below, the Company may, at its option, by majority vote of the
Board of Directors and a majority vote of the Continuing Directors,  at any time
after the  occurrence  of a Triggering  Event,  exchange all or part of the then
outstanding  and  exercisable  Rights (which shall not include  Rights that have
become void pursuant to the provisions of Section 7(e) hereof) for Common Shares
at an exchange  ratio of one Common Share per Right,  appropriately  adjusted to
reflect any stock split, stock dividend or similar  transaction  occurring after
the date hereof (such exchange ratio being hereinafter referred to as the "Ratio
of Exchange").  Notwithstanding the foregoing,  the Board of Directors shall not
be  empowered to effect such  exchange at any time after any Person  (other than
the Company,  any  Subsidiary of the Company,  any employee  benefit plan of the
Company or any such  Subsidiary,  or any  entity  holding  Common  Shares for or
pursuant  to the  terms of any such  plan),  together  with all  Affiliates  and
Associates of such Person,  becomes the  Beneficial  Owner of 50% or more of the
Common Shares then outstanding.

            (b) Immediately  upon the action of the Board of Directors  ordering
the  exchange of any Rights  pursuant to  subsection  (a) of this Section 24 and
without any further  action and without any notice,  the right to exercise  such
Rights shall terminate and the only right  thereafter of a holder of such Rights
shall be to receive  that  number of Common  Shares  equal to the number of such
Rights  held by such holder  multiplied  by the Ratio of  Exchange.  The Company
shall 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
                                      -29-

<PAGE>

such  exchange.  The Company  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 7(e) hereof)
held by each holder of Rights.

            (c) In the event that there shall not be  sufficient  Common  Shares
issued but not  outstanding or authorized but unissued to permit any exchange of
Rights as  contemplated  in  accordance  with Section  24(a),  the Company shall
either take such  action as may be  necessary  to  authorize  additional  Common
Shares for issuance upon exchange of the Rights or alternatively,  at the option
of a majority of the Board of Directors, with respect to each Right (i) pay cash
in an amount equal to the Current  Value (as  hereinafter  defined),  in lieu of
issuing  Common  Shares  in  exchange  therefor,  or (ii)  issue  debt or equity
securities or a combination thereof,  having a value equal to the Current Value,
in lieu of issuing  Common  Shares in exchange  for each such  Right,  where the
value  of  such  securities  shall  be  determined  by a  nationally  recognized
investment  banking firm  selected by the Board of Directors by majority vote of
the Board of Directors,  or (iii)  deliver any  combination  of cash,  property,
Common Shares and/or other securities  having a value equal to the Current Value
in exchange for each Right. For purposes of this Section 24(c) only, the Current
Value shall mean the product of the  current  per share  market  price of Common
Shares  (determined  pursuant to Section 11(d) on the date of the  occurrence of
the event  described  above in  subparagraph  (a))  multiplied  by the number of
Common Shares for which the Right  otherwise would be exchangeable if there were
sufficient shares available. To the extent that the Company determines that some
action need be taken  pursuant  to clauses  (i),  (ii) or (iii) of this  Section
24(c), the Board of Directors may temporarily  suspend the exercisability of the
Rights  for a period of up to sixty  (60) days  following  the date on which the
event  described  in Section  24(a)  shall have  occurred,  in order to seek any
authorization of additional  Common Shares and/or to decide the appropriate form
of  distribution to be made pursuant to the above provision and to determine the
value thereof.  In the event of any such  suspension,  the Company shall issue a
public  announcement  stating  that the  exercisability  of the  Rights has been
temporarily suspended.

             (d) The Company shall not be required to issue  fractions of Common
Shares or to distribute certificates which evidence fractional Common Shares. In
lieu of such  fractional  Common  Shares,  there shall be paid to the registered
holders of the Rights  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 (as  determined
pursuant to the second sentence of Section 11(d) hereof).

            (e) The Company may, at its option, by majority vote of the Board of
Directors,  at any time  before  any  Person  has  become an  Acquiring  Person,
exchange all or part of the then outstanding  Rights for rights of substantially
equivalent  value, as determined  reasonably and with good faith by the Board of
Directors, based upon the advice of one or more nationally recognized investment
banking firms.

            (f) Immediately  upon the action of the Board of Directors  ordering
the  exchange of any Rights  pursuant to  subsection  (e) of this Section 24 and
without any further  action and without any notice,  the right to exercise  such
Rights shall terminate and the only right  thereafter of a holder of such Rights
shall be to  receive  that  number of rights in  exchange  therefor  as has been
determined by the Board of Directors in accordance  with  subsection  (e) above.
The Company shall give public notice of any such  exchange;  PROVIDED,  HOWEVER,
that the failure to give,  or any defect in,  such  notice  shall not affect the
validity of such exchange.  The Company shall 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 transfer  agent for the Common Shares of the Company.
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 Rights will be effected.

      Section 25.  NOTICE OF CERTAIN EVENTS.

            (a) In case the Company  shall  propose to effect or permit to occur
any Triggering  Event  described in Section  11(a)(ii)(A)  or  11(a)(ii)(B) or a
Section 13 Event, the Company shall give notice thereof to each holder of Rights
in  accordance  with  Section  26 hereof  at least  twenty  (20)  days  prior to
occurrence of such Triggering Event or such Section 13 Event.

notice of the  occurrence  of such event,  which shall specify the event and the
consequences  of the event to holders of Rights under Sections  11(a)(ii) and 13
hereof.

      Section 27.  SUPPLEMENTS AND AMENDMENTS.  Prior to the Distribution  Date,
the Company may supplement or amend this Agreement in any respect  (including an
increase or decrease in the stock  ownership  percentage  at which a  Beneficial
Owner of Common  Shares  outstanding  becomes an Acquiring  Person)  without the
approval of any holders of Rights and the Rights Agent shall,  if the Company so
directs,  execute such supplement or amendment.  From and after the Distribution
Date, the Company and the Rights Agent may from time to time supplement or amend
this  Agreement  without  the  approval of any holders of Rights in order to (i)
cure any ambiguity,  (ii) correct or supplement any provision  contained  herein
which may be defective or inconsistent with any other provisions  herein,  (iii)
shorten or lengthen any time period hereunder (which  lengthening or shortening,
following  the first  occurrence of an event set forth in the proviso to Section
23(a)  hereof,  shall be effective  only if there are  Continuing  Directors and
shall require the  concurrence  of a majority of such  Continuing  Directors) or
(iv) to change or  supplement  the  provisions  hereunder in any manner that the
Company may deem necessary or desirable and that shall not adversely  affect the
interests  of the  holders  of  Rights  (other  than an  Acquiring  Person or an
Affiliate or Associate of an Acquiring Person); provided, this Agreement may not
be  supplemented  or  amended  to  lengthen,  pursuant  to clause  (iii) of this
sentence,  (A) a time period relating to when the Rights may be redeemed at such
time as the Rights are not then  redeemable  or (B) any other time period unless
such  lengthening is for the purpose of protecting,  enhancing or clarifying the
rights  of,  and/or  the  benefits  to, the   holders  of  Rights (other than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person).  Upon the
delivery of a certificate  from  an  appropriate  officer  of  the  Company that
states that the proposed supplement or amendment is in compliance with the terms
of this Section 27, the Rights Agent shall execute such supplement or amendment.
Prior to the Distribution  Date,  the  interests  of the holders of Rights shall
be deemed coincident with the interests of the holders of Common Shares.

      Section 28. SUCCESSORS. All the covenants and provisions of this Agreement
by or for the benefit of the Company or the Rights Agent shall bind and inure to
the benefit of their respective successors and assigns hereunder.

      Section 29. DETERMINATIONS AND ACTIONS BY THE BOARD OF DIRECTORS, ETC. For
all purposes of this  Agreement,  any calculation of the number of Common Shares
outstanding at any particular  time,  including for purposes of determining  the
particular  percentage of such outstanding  Common Shares of which any Person is
the Beneficial Owner, shall be made in accordance with the last sentence of Rule
13d-3(d)(1)(i)  of the General Rules and Regulations under the Exchange Act. The
Board of Directors of the Company (and, where specifically  provided for herein,
the  Continuing  Directors)  shall have the  exclusive  power and  authority  to
administer  this  Agreement  and to exercise all rights and powers  specifically
granted to the Board,  or the  Company  (or,  where  specifically  provided  for
herein,  the Continuing  Directors),  or as may be necessary or advisable in the
administration of this Agreement,  including,  without limitation, the right and
power to (i)  interpret  the  provisions  of this  Agreement  and (ii)  make all
determinations  deemed  necessary or advisable  for the  administration  of this
Agreement  (including a  determination  to redeem or not redeem the Rights or to

                                      -32-

<PAGE>

amend  the  Agreement).  All such  actions,  calculations,  interpretations  and
determinations  (including, for purposes of clause (y) below, all omissions with
respect  to the  foregoing)  which  are  done or made by the  Board  (or,  where
specifically  provided for herein,  by the Continuing  Directors) in good faith,
shall (x) be final, conclusive and binding on the Company, the Rights Agent, the
holders of the Rights Certificates and all other parties and (y) not subject the
Board or the Continuing Directors to any liability to the holders of the Rights.

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

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

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

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

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

                     SERIES A PARTICIPATING PREFERRED STOCK

                          OF SILICON VALLEY GROUP, INC.


      The  undersigned, Papken S. Der Torossian and Larry W. Sonsini, do  hereby
certify:

      1. That they are the duly  elected  and acting  Chairman   and  Secretary,
respectively,  of  Silicon  Valley  Group,  Inc.,  a Delaware  corporation  (the
"Corporation").

      2. That pursuant to the authority conferred upon the Board of Directors by
the Restated  Certificate of  Incorporation  of the said  Corporation,  the said
Board of  Directors  on  September  25, 1996  adopted the  following  resolution
creating a series of 50,000  shares of Preferred  Stock  designated  as Series A
Participating Preferred Stock:

      "RESOLVED, that pursuant to the authority vested in the Board of Directors
of the corporation by the Restated  Certificate of  Incorporation,  the Board of
Directors  does hereby  provide for the issue of a series of Preferred  Stock of
the  Corporation,  to be designated  "Series A Participating  Preferred  Stock,"
initially  consisting of 50,000 shares and to the extent that the  designations,
powers,   preferences   and   relative   and  other   special   rights  and  the
qualifications,  limitations  and  restrictions  of the  Series A  Participating
Preferred  Stock are not stated and  expressed  in the Restated  Certificate  of
Incorporation,  does hereby fix and herein state and express such  designations,
powers,   preferences   and   relative   and  other   special   rights  and  the
qualifications, limitations and restrictions thereof, as follows (all terms used
herein which are defined in the Restated  Certificate of Incorporation  shall be
deemed to have the meanings provided therein):

      Section 1.  DESIGNATION  AND AMOUNT.  The shares of such  series  shall be
designated as "Series A Participating Preferred Stock," and the number of shares
constituting such series shall be 50,000.

      Section 2.  DIVIDENDS AND DISTRIBUTIONS.

            (A)  Subject to the prior and  superior  right of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the shares
of Series A Participating Preferred Stock with respect to dividends, the holders
of shares of Series A Participating Preferred Stock shall be entitled to receive
when,  as and if  declared  by the  Board  of  Directors  out of  funds  legally
available for the purpose,  quarterly  dividends payable in cash on the last day
of  September,  December,  March and June 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

                                       -1-


<PAGE>

fraction of a share of Series A Participating  Preferred Stock, in an amount per
share  (rounded to the  nearest  cent) equal to,  subject to the  provision  for
adjustment  hereinafter set forth, 1,000 times the aggregate per share amount of
all cash  dividends,  and 1,000 times the aggregate per share amount (payable in
kind) of all  non-cash  dividends or other  distributions  other than a dividend
payable in shares of Common Stock or a subdivision of the outstanding  shares of
Common Stock (by reclassification or otherwise), declared on the Common Stock of
the Corporation (the "Common Stock") since the immediately  preceding  Quarterly
Dividend Payment Date, or, with respect to the first Quarterly  Dividend Payment
Date,  since the first  issuance of any share or fraction of a share of Series A
Participating  Preferred  Stock. In the event the Corporation  shall at any time
after October 15, 1996 (the "Rights  Declaration Date") (i) declare any dividend
on  Common  Stock  payable  in  shares  of  Common  Stock,  (ii)  subdivide  the
outstanding  Common Stock, or (iii) combine the outstanding  Common Stock into a
smaller number of shares,  then in each such case the amount to which holders of
shares of Series A Participating 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  Participating  Preferred  Stock as  provided  in  paragraph  (A) above
immediately  after it declares a dividend or  distribution  on the Common  Stock
(other than a dividend payable in shares of Common Stock).

            (c) Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A  Participating  Preferred  Stock from the Quarterly  Dividend
Payment  Date  next  preceding  the  date of issue of such  shares  of  Series A
Participating  Preferred Stock, 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  Participating  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  Participating  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 Participating Preferred Stock
entitled to receive  payment of a dividend  or  distribution  declared  thereon,
which  record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

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

            (a) Subject to the provision for adjustment  hereinafter  set forth,
each share of Series A  Participating  Preferred  Stock shall entitle the holder
thereof to 1,000 votes on all matters submitted to a vote of the stockholders of
the Corporation. In the event the Corporation shall at any time after the Rights
Declaration  Date (i) declare any dividend on Common Stock  payable in shares of

                                       -2-

<PAGE>

Common Stock, (ii) subdivide the outstanding  Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the  number  of  votes  per  share  to  which  holders  of  shares  of  Series A
Participating  Preferred  Stock were  entitled  immediately  prior to such event
shall be adjusted by  multiplying  such number by a fraction,  the  numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

            (b) Except as  otherwise  provided  herein or by law, the holders of
shares of Series A  Participating  Preferred  Stock and the holders of shares of
Common Stock shall vote together as one class on all matters submitted to a vote
of stockholders of the Corporation.

            (c) Except as  required  by law,  holders of Series A  Participating
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) The  Corporation  shall not  declare any  dividend  on, make any
distribution  on, or redeem or purchase or otherwise  acquire for  consideration
any shares of Common Stock after the first  issuance of a share or fraction of a
share of Series A Participating Preferred Stock unless concurrently therewith it
shall  declare a  dividend  on the  Series A  Participating  Preferred  Stock as
required by Section 2 hereof.

            (b) Whenever quarterly dividends or other dividends or distributions
payable on the Series A  Participating  Preferred Stock as provided in Section 2
are in  arrears,  thereafter  and until all  accrued  and unpaid  dividends  and
distributions,  whether  or not  declared,  on shares of Series A  Participating
Preferred Stock  outstanding shall have been paid in full, the Corporation shall
not

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

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

                        (C)   redeem or purchase or otherwise  acquire  for con-
sideration  shares of any stock  ranking on a parity  (either as to dividends or
upon  liquidation,  dissolution  or winding up) with the Series A  Participating
Preferred Stock, provided that the Corporation may at any time redeem,  purchase
or otherwise  acquire  shares of any such parity stock in exchange for shares of
any stock of the  Corporation  ranking  junior  (either as to  dividends or upon
dissolution,  liquidation or winding up) to the Series A Participating Preferred
Stock;
                                       -3-

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

            (c)  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  Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled 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 to be  created by  resolution  or  resolutions  of the Board of
Directors,  subject to the  conditions  and  restrictions  on issuance set forth
herein.

      Section 6.  LIQUIDATION, DISSOLUTION OR WINDING UP.

            (a) Upon any  liquidation  (voluntary or otherwise),  dissolution or
winding up of the Corporation,  no distribution  shall be made to the holders of
shares of stock  ranking  junior  (either as to dividends  or upon  liquidation,
dissolution or winding up) to the Series A Participating Preferred Stock unless,
prior thereto,  the holders of shares of Series A Participating  Preferred Stock
shall have received one hundred twenty-five  thousand dollars  ($125,000.00) per
share,  plus an amount equal to accrued and unpaid  dividends and  distributions
thereon,  whether or not  declared,  to the date of such  payment (the "Series A
Liquidation Preference"). Following the payment of the full amount of the Series
A  Liquidation  Preference,  no  additional  distributions  shall be made to the
holders  of shares of  Series A  Participating  Preferred  Stock  unless,  prior
thereto, the holders of shares of Common Stock shall have received an amount per
share (the "Common  Adjustment")  equal to the quotient obtained by dividing (i)
the Series A Liquidation  Preference by (ii) 1,000 (as appropriately adjusted as
set forth in  subparagraph  (C) below to reflect  such  events as stock  splits,
stock  dividends  and  recapitalization  with respect to the Common Stock) (such
number in clause (ii), the  "Adjustment  Number").  Following the payment of the
full amount of the Series A Liquidation  Preference and the Common Adjustment in
respect of all outstanding shares of Series A Participating  Preferred Stock and
Common Stock,  respectively,  holders of Series A Participating  Preferred Stock
and  holders  of  shares  of  Common  Stock  shall  receive  their  ratable  and
proportionate  share of the remaining  assets to be  distributed in the ratio of
the  Adjustment  Number to 1 with  respect  to such  Preferred  Stock and Common
Stock, on a per share basis, respectively.

            (b) In the  event,  however,  that there are not  sufficient  assets
available to permit  payment in full to the Series A Liquidation  Preference and
the  liquidation  preferences  of all other series of Preferred  Stock,  if any,
which  rank on  a parity with the  Series A Participating  Preferred Stock, then

                                       -4-


<PAGE>

such remaining assets shall be distributed ratably to the holders of such parity
shares in proportion to their respective liquidation preferences.  In the event,
however,  that there are not  sufficient  assets  available to permit payment in
full of the Common  Adjustment,  then such remaining assets shall be distributed
ratably to the holders of Common Stock.

            (c) In the event the Corporation  shall at any time after the Rights
Declaration  Date (i) declare any dividend on Common Stock  payable in shares of
Common Stock, (ii) subdivide the outstanding  Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the  Adjustment  Number  in  effect  immediately  prior to such  event  shall be
adjusted by multiplying  such  Adjustment  Number by a fraction the numerator of
which is the number of shares of Common Stock outstanding immediately after such
event and the  denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.

      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 any other property, then in any such case the shares of
Series A  Participating  Preferred  Stock  shall at the same  time be  similarly
exchanged  or changed  in an amount  per share  (subject  to the  provision  for
adjustment  hereinafter set forth) equal to 1,000 times the aggregate  amount of
stock, securities, cash and/or any other property (payable in kind), as the case
may be,  into  which or for which  each  share of  Common  Stock is  changed  or
exchanged.  In the  event the  Corporation  shall at any time  after the  Rights
Declaration  Date (i) declare any dividend on Common Stock  payable in shares of
Common Stock, (ii) subdivide the outstanding  Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount set forth in the  preceding  sentence with respect to the exchange or
change of shares of Series A Participating  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 Participating  Preferred
Stock shall not be redeemable.

      Section 9. RANKING. The Series A Participating  Preferred Stock shall rank
junior  to all  other  series  of the  Corporation's  Preferred  Stock as to the
payment of dividends  and the  distribution  of assets,  unless the terms of any
such series shall provide otherwise.

      Section 10.  AMENDMENT.  The Restated  Certificate of Incorporation of the
Corporation  shall not be further  amended in any manner which would  materially
alter or change  the  powers,  preference  or  special  rights  of the  Series A
Participating  Preferred  Stock  so as to  affect  them  adversely  without  the
affirmative vote of the holders of a majority or more of the outstanding  shares
of Series A Participating Preferred Stock, voting separately as a class.

      Section 11. FRACTIONAL SHARES. Series A Participating  Preferred Stock may
be issued in fractions of a share which shall entitle the holder,  in proportion

to  such  holder's  fractional  shares,  to  exercise  voting  rights,   receive

rights of holders of Series A Participating Preferred Stock.

      RESOLVED  FURTHER,  that  the  President  or any  Vice  President  and the
Secretary or any  Assistant  Secretary of this  corporation  be, and they hereby
are, authorized and directed to prepare and file a Certificate of Designation of
Rights,  Preferences and Privileges in accordance with the foregoing  resolution
and the  provisions  of Delaware  law and to take such  actions as they may deem
necessary or appropriate to carry out the intent of the foregoing resolution."

      3.  That  the  authorized  number  of  shares  of  Preferred  Stock of the
Corporation is 1,000,000 and that no such Preferred Stock has been issued.
