ITEM 1.   DESCRIPTION OF SECURITIES TO BE REGISTERED.

    On September 13, 1996, the Board of  Directors of Opinion Research
Corporation (the "Company") adopted a Stockholder Rights Plan (the
"Plan"), providing for the distribution of one purchase right (a "Right")
for each share of the Company's common stock, par value $.01 per share
(the "Common Stock"), outstanding as of October 3, 1996 (the "Record
Date").  Each Right entitles the registered holder, upon the occurrence of
certain events described below, to purchase from the Company a unit
consisting of one one-thousandth of a newly issued series of  Preferred
Stock of the Company designated "Series A Junior Participating Preferred
Stock"  (a "Unit"),  par value $0.01 per share (the "Preferred Stock"), at
a purchase price of  $25 per Unit (the "Purchase Price"), subject to
adjustment.  The description and terms of the Rights are set forth in a
Rights Agreement (the "Rights Agreement") between the Company and
StockTrans, Inc.  (the "Rights Agent"), and attached as an Exhibit hereto.

    Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate Rights
Certificates will be distributed.  The Rights will separate from the
Common Stock and a Distribution Date will occur upon the earlier of (i)
ten (10) days following a public announcement that a person or group of
affiliated or associated persons, other than an Exempted Person (as
defined below), (an "Acquiring Person") has acquired, or obtained the
right to acquire, beneficial ownership of  20% or more of the outstanding
shares of Common Stock (the "Stock Acquisition Date") or (ii) ten (10)
business days following the commencement of a tender offer or exchange
offer that would result in a person or group beneficially owning 20% or
more of such outstanding shares of Common Stock.  Until the Distribution
Date, (i) the Rights will be evidenced by the Common Stock certificates
and will be transferred with and only with such Common Stock certificates,
(ii) new Common Stock certificates will contain a notation incorporating
the Rights Agreement by reference and (iii) the surrender for transfer of
any certificates for Common Stock outstanding will also constitute the
transfer of the Rights associated with the Common Stock represented by
such certificate.

    The Rights are not exercisable until the Distribution Date and
will expire at the close of business on October 3, 2006 unless earlier
redeemed by the Company as described below.  At no time will the Rights
have any voting power.

    As soon as practicable after the Distribution Date, Rights
Certificates will be mailed to holders of record of the Common Stock as of
the close of business on the Distribution Date and, thereafter, the
separate Rights Certificates alone will represent the Rights. Except as
otherwise determined by the Board of Directors, only shares of Common
Stock prior to the Distribution Date will be issued with Rights.

    In the event that an Acquiring Person, other than an Exempted
Person, as defined below, becomes the beneficial owner of  20% or more of
the then outstanding shares of Common Stock (unless such acquisition is
made pursuant to a tender or exchange offer  for all outstanding shares of
the Company, at a price determined by a majority of the independent
directors of the Company who are not representatives, nominees, affiliates



                                       2
<PAGE>
 
or associates of an Acquiring Person to be fair and otherwise in the best
interest of the Company and its stockholders after receiving advice from
one or more investment banking firms (a "Qualified Offer")), each holder
of a Right will thereafter have the right to receive, upon exercise,
Common Stock (or, in certain circumstances, cash, property or other
securities of the Company), having a value equal to four times the
Exercise Price of the Right.  The Exercise Price is the Purchase Price
times the number of shares of Common Stock associated with each Right
(initially, one). Notwithstanding any of the foregoing, following the
occurrence of any of the events set forth in this paragraph (the "Flip-In
Events"), all Rights that are, or (under certain circumstances specified
in the Rights Agreement) were, beneficially owned by any Acquiring Person
will be null and void.  However, Rights are not exercisable following the
occurrence of any of the Flip-In Events set forth above until such time as
the Rights are no longer redeemable by the Company as set forth below.

    Any person who, together with all affiliates and associates of
such person, is the beneficial owner of Common Stock, options and/or
warrants exercisable for shares of Common Stock representing 20% or more
of the shares of Common Stock outstanding on September 13, 1996 (the
"Rights Dividend Declaration Date") will be an "Exempted Person."   In
addition, any person who, together  with all affiliates and associates of
such person, becomes the beneficial owner of Common Stock, options and/or
warrants exercisable for shares of Common Stock representing  20% or more
of the shares of Common Stock then outstanding as a result of a purchase
by the Company or any of its subsidiaries of shares of Common Stock will
also be an "Exempted Person."  However, any such person will no longer be
deemed to be an Exempted Person and will be deemed to be an Acquiring
Person if such person, together with all affiliates and associates of such
person, becomes the beneficial owner, at any time after the Rights
Dividend Declaration Date, of additional securities representing 1000 or
more shares of  Common Stock, except if such additional securities are
acquired (x) pursuant to the exercise of options or warrants to purchase
Common Stock outstanding and beneficially owned by such person as of the
date such person became the beneficial owner of 20% or more of the then
outstanding shares of Common Stock or as a result of an adjustment to the
number of shares of Common Stock for which such options or warrants are
exercisable pursuant to the terms thereof, or  (y) as a result of a stock
split, stock dividend or the like.  A purchaser, assignee or transferee of
the shares of Common Stock (or options or warrants exercisable for Common
Stock) of an Exempted Person will not thereby become an Exempted Person.

    In the event that following the Stock Acquisition Date: (i) the
Company engages in a merger or business combination transaction in which
the Company is not the surviving corporation (other than a merger that
follows a tender offer determined to be fair to the stockholders of the
Company, as described above); (ii) the Company engages in a merger or
business combination transaction in which the Company is the surviving
corporation and the Common Stock is changed or exchanged; or (iii) 50% or
more of the Company's assets or earning power is sold or transferred, each
holder of a Right (except Rights that have previously been voided as set
forth above) shall thereafter have the right to receive, upon exercise of
the Right, common stock of the acquiring company having a value equal to
four times the Exercise Price of the Right.



                                       3
<PAGE>
 
    The Purchase Price and the number of Units of Preferred Stock or
other securities or property issuable upon exercise of the Rights are
subject to adjustment from time to time to prevent dilution (i) in the
event of a stock dividend on, or a subdivision, combination or
reclassification of, the Preferred Stock; (ii) if holders of the Preferred
Stock are granted certain rights or warrants to subscribe for Preferred
Stock or convertible securities at less than the current market price of
the Preferred Stock; or (iii) upon the distribution to holders of the
Preferred Stock of evidences of indebtedness or assets (excluding regular
quarterly cash dividends) or of subscription rights or warrants (other
than those referred to above).

    With certain exceptions, no adjustments in the Purchase Price will
be required until cumulative adjustments amount to at least 1% of the
Purchase Price. No fractional Units will be issued and, in lieu thereof,
an adjustment in cash will be made based on the market price of the
Preferred Stock on the last trading date prior to the date of exercise.

    At any time until twenty (20) days following the Stock Acquisition
Date, the Company may redeem the Rights in whole, but not in part, at a
price of $0.001 per Right.  Under certain circumstances, the decision to
redeem shall require the concurrence of a majority of the Continuing
Directors, as defined below. Immediately upon the action of the Board of
Directors ordering redemption of the Rights, the Rights will terminate and
the only right of the holders of Rights will be to receive the $0.001
redemption price.

    The term "Continuing Director" means any member of the Board of
Directors of the Company who was a member of the Board prior to the
adoption of the Rights Plan and any person who is subsequently elected to
the Board if such person is recommended or approved by a majority of the
Continuing Directors, but does not include an Acquiring Person, or an
affiliate or associate of an Acquiring Person, or any representative of
the foregoing entities.

    Until a Right is exercised, the holder thereof, as such, will have
no rights as a stockholder of the Company, including, without limitation,
the right to vote or to receive dividends.  While the distribution of the
Rights will not be taxable to stockholders or to the Company, stockholders
may, depending upon the circumstances, recognize taxable income in the
event that the Rights become exercisable for Common Stock (or other
consideration) of the Company, as set forth above.

    Other than those provisions relating to the principal economic
terms of the Rights, any of the provisions of the Rights Agreement may be
amended by the Board of Directors of the Company prior to the Distribution
Date.  After the Distribution Date, the provisions of the Rights Agreement
may be amended by the Board (in certain circumstances, with the
concurrence of the Continuing Directors) in order to cure any ambiguity,
to make changes that do not adversely affect the interests of holders of
Rights (excluding the interest 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 at such time as the Rights are not redeemable.



                                       4

    The Rights have certain anti-takeover effects, and will cause
substantial dilution to a person or group that attempts to acquire the
Company in certain circumstances.  Accordingly, the existence of the
Rights may deter certain acquirors from making takeover proposals or
tender offers.  The Rights, however, are not intended to prevent a
takeover, but rather are designed to  enhance the ability of the Board of
Directors to negotiate with a potential acquiror on behalf of all of the
stockholders.

    The Rights Agreement between the Company and the Rights Agent that
specifies the terms of the Rights is attached hereto as Exhibit 1, and is
incorporated herein by reference.  The foregoing description of the Rights
does not purport to be complete and is qualified in its entirety by
reference to Exhibit 1 hereto.

    WHEREAS, on September 13, 1996 (the "Rights Dividend Declaration

authorized the issuance of one Right (as such number may hereinafter be
adjusted pursuant to the provisions of Section 11(p) hereof) for each
share of Common Stock issued between the Record Date (whether originally
issued or delivered from the Company's treasury) and the Distribution Date
(as defined in Section 3 hereof), each Right initially representing the
right to purchase one one-thousandth of a share (a "Unit") of Series A
Junior Participating Preferred Stock (the "Preferred Stock") of the
Company having the rights, powers and preferences set forth in the form of

otherwise; PROVIDED, HOWEVER, that a Person shall not be deemed the "Beneficial

understanding (whether or not in writing), for the purpose of acquiring,
holding, voting (except pursuant to a revocable proxy as described in the
proviso to subparagraph (ii) of this paragraph (c)) or disposing of any voting

Owner" of, or to "beneficially own," any securities acquired through such
Person's participation in good faith in a firm commitment underwriting
until the expiration of forty (40) days after the date of such
acquisition.

      (d) "Business Day" shall mean any day other than a Saturday, Sunday or a

Acquiring Person, or a representative of an Acquiring Person or of any such

an Affiliate or Associate of an Acquiring Person, or a representative of an
Acquiring Person or of any such Affiliate or Associate, if such Person's
nomination for election or election to the Board is recommended or approved by a
majority of the Continuing Directors.

the shares of Common Stock then outstanding because of a reduction in the number
of outstanding shares of Common Stock then outstanding as a result of the
purchase by the Company or a Subsidiary of the Company of shares of Common
Stock; PROVIDED, HOWEVER, that any such Person described in clause (ii) shall no
longer be deemed to be an Exempted Person and shall be deemed an Acquiring
Person if such Person, together with all Affiliates and Associates of such

Common Stock for which such options or warrants are exercisable pursuant to the
terms thereof, or (y) as a result of a stock split, stock dividend or the like.

Date occurs before the Record Date, the close of business on the Record Date),
or (ii) the close of business on the tenth business day (or such later date as
the Board of Directors of the Company


                                       5

shall determine) after the date that a tender or exchange offer by any Person
(other than the Company, any Subsidiary of the Company, any employee benefit
plan of the Company or of any Subsidiary of the Company, or any Person
organized, appointed or established by the Company for or pursuant to the terms
of any such plan) is first published or sent or given within the meaning of Rule
14d-2(a) of the General Rules and Regulations under the Exchange Act, if upon
consummation thereof, such Person would be the Beneficial Owner of 20% or more
of the shares of Common Stock then outstanding (the earlier of (i) and (ii)
being herein referred to as the "Distribution Date"), (x) the Rights will be
evidenced (subject to the provisions of paragraph (b) of this Section 3) by the
certificates for the Common Stock registered in the names of the holders of the
Common Stock (which certificates for Common Stock shall be deemed also to be
certificates for Rights) and not by separate certificates, and (y) the Rights
will be transferable only in connection with the transfer of the underlying
shares of Common Stock (including a transfer to the Company). As soon as
practicable after the Distribution Date, the Rights Agent will send by first-
class, insured, postage prepaid mail, to each record holder of the Common Stock
as of the close of business on the Distribution Date, at the address of such
holder shown on the records of the Company, one or more rights certificates, in
substantially the form of Exhibit B hereto (the "Rights Certificates"),
evidencing one right for each share of Common Stock so held, subject to
adjustment as provided herein. In the event that an adjustment in the number of
Rights per share of Common Stock has been made pursuant to Section 11(p) hereof,
at the time of distribution of the Rights Certificates, the Company shall make
the necessary and appropriate rounding adjustments (in accordance 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
and after the Distribution Date, the Rights will be evidenced solely by such
Rights Certificates.

       (b) As promptly as practicable following the Record Date, the Company
will send a copy of a Summary of Rights, in substantially the form attached
hereto as Exhibit C (the "Summary of Rights"), by first-class, postage prepaid
mail, to each record holder of the Common Stock as of the close of business on
the Record Date, at the address of such holder shown on the records of the
Company. With respect to certificates for the Common Stock outstanding as of the
Record Date, until the Distribution Date, the Rights will be evidenced by such
certificates for the Common Stock and the registered holders of the Common Stock
shall also be the registered holders of the associated Rights. Until the earlier
of the



                                       6
<PAGE>
 
Distribution Date or the Expiration Date (as such term is defined in Section 7
hereof), the transfer of any certificates representing shares of Common Stock in
respect of which Rights have been issued shall also constitute the transfer of
the Rights associated with such shares of Common Stock.

       (c) Rights shall be issued in respect of all shares of Common Stock which
are issued (whether originally issued or from the Company's treasury) after the
Record Date but prior to the earlier of the Distribution Date or the Expiration
Date. Certificates representing such shares of Common Stock 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 the Rights Agreement between Opinion Research Corporation (the
"Company") and StockTrans, Inc. (the "Rights Agent"), dated as of September 13,
1996 (the "Rights Agreement"), the terms of which are hereby incorporated herein
by reference and a copy of which is on file at the principal offices of the
Rights Agent. Under certain circumstances, as set forth in the Rights Agreement,
such Rights will be evidenced by separate certificates and will no longer be
evidenced by this certificate. The Rights Agent will mail to the holder of this
certificate a copy of the Rights Agreement, as in effect on the date of mailing,
without charge promptly 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 Stock represented by such
certificates shall be evidenced by such certificates alone and registered
holders of Common Stock shall also be the registered holders of the associated
Rights, and the transfer of any of such certificates shall also constitute the
transfer of the Rights associated with the Common Stock represented by such
certificates.

    Section 4.  FORM OF RIGHTS CERTIFICATES.

       (a) The Rights Certificates (and the forms of election to purchase and of
assignment to be printed on the reverse thereof) shall each be substantially in
the form set forth in Exhibit B hereto and may have such marks of identification
or designation and such legends, summaries or endorsements printed thereon as
the Company may deem appropriate and as are not inconsistent with the provisions
of this



                                       7
<PAGE>
 
Agreement, or as may be required to comply with any applicable law or with any
rule or regulation made pursuant thereto or with any rule or regulation of any
stock exchange on which the Rights may from time to time be listed, or to
conform to usage. Subject to the provisions of Section 11 and Section 22 hereof,
the Rights Certificates, whenever distributed, shall be dated as of the Record
Date and on their face shall entitle the holders thereof to purchase such number
of one one-thousandths of a share of Preferred Stock as shall be set forth
therein at the price set forth therein (such exercise price per one one-
thousandth of a share, the "Purchase Price"), but the amount and type of
securities purchasable upon the exercise of each Right and the Purchase Price
thereof 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 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 such
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 Vice Chairman, its President or any Vice
President, either manually or by facsimile signature, and shall have affixed
thereto the Company's seal or a facsimile thereof which shall be attested by the
Secretary or an Assistant Secretary of the Company, either manually or by
facsimile signature. The Rights Certificates shall be countersigned by the
Rights Agent, either manually or by facsimile signature, and shall not be valid
for any purpose unless so 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
Certificates 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 shall keep or cause
to be kept, at its principal office or offices designated as the appropriate
place for surrender of Rights Certificates upon exercise or transfer, 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 Section 4(b), Section 7(e) and Section
14 hereof, at any time after the close of business on the Distribution Date, and
at or prior to the close of business on the Expiration Date, any Rights
Certificate or Certificates may be transferred, split up, combined or exchanged
for another Rights Certificate or Certificates, entitling the registered holder
to purchase a like number of one one-thousandths of a share of Preferred Stock
(or, following a Triggering Event, Common Stock, other securities, cash or


                                       9
<PAGE>
 
other assets, as the case may be) as the Rights Certificate or Certificates
surrendered then entitled such holder (or former holder in the case of a
transfer) to purchase. Any registered holder desiring to transfer, split up,
combine or exchange any Rights Certificate or Certificates shall make such
request in writing delivered to the Rights Agent, and shall surrender the Rights
Certificate or Certificates to be transferred, split up, combined or exchanged
at the principal office or offices 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 Section 4(b), Section 7(e) and Section 14 hereof,
countersign and deliver to the Person entitled thereto a Rights Certificate or
Rights Certificates, as the case may be, as so requested. The Company may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer, split up, combination or
exchange of Rights Certificates.

       (b) Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Rights Certificate, and, in case of loss, theft or destruction, of indemnity
or security reasonably satisfactory to them, and 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 execute and deliver a new Rights Certificate of like
tenor to the Rights Agent for countersignature and delivery to the registered
owner 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 Section 7(e) hereof, the registered holder of any Rights
Certificate may exercise the Rights evidenced thereby (except as otherwise
provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c), Section 11(a)(iii) and Section 23(a)
hereof) in whole or in part at any time after



                                      10
<PAGE>
 
the Distribution Date upon surrender of the Rights Certificate, with the form of
election to purchase and the certificate on the reverse side thereof duly
executed, to the Rights Agent at the principal office or offices of the Rights
Agent designated for such purpose, together with payment of the aggregate
Purchase Price with respect to the total number of one one-thousandths of a
share of Preferred Stock (or other securities, cash or other assets, as the case
may be) as to which such surrendered Rights are then exercisable, at or prior to
the earlier of (i) the close of business on October 3, 2006, (the "Final
Expiration Date"), or (ii) the time at which the Rights are redeemed as provided
in Section 23 hereof (the earlier of (i) and (ii) being herein referred to as
the "Expiration Date").

       (b) The Purchase Price for each one one-thousandth of a share of
Preferred Stock pursuant to the exercise of a Right shall initially be $25.00,
and shall be subject to adjustment from time to time as provided in Sections 11
and 13(a) hereof and shall be payable in accordance with paragraph (c) below.

       (c) Upon receipt of a Rights Certificate representing exercisable Rights,
with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price per one one-thousandth of a share of Preferred Stock (or other shares,
securities, cash or other assets, as the case may be) to be purchased as set
forth below and an amount equal to any applicable transfer tax, the Rights Agent
shall, subject to Section 20(k) hereof, thereupon promptly (i) (A) requisition
from any transfer agent of the shares of Preferred Stock (or make available, if
the Rights Agent is the transfer agent for such shares) certificates for the
total number of one one-thousandths of a share of Preferred Stock to be
purchased and the Company hereby irrevocably authorizes its transfer agent to
comply with all such requests, or (B) if the Company shall have elected to
deposit the total number of shares of Preferred Stock issuable upon exercise of
the Rights hereunder with a depositary agent, requisition from the depositary
agent depositary receipts representing such number of one one-thousandths of a
share of Preferred Stock as are to be purchased (in which case certificates for
the shares of Preferred Stock represented by such receipts shall be deposited by
the transfer agent with the depositary agent) and the Company shall direct the
depositary agent to comply with such request, (ii) requisition from the Company
the amount of cash, if any, to be paid in lieu of fractional shares in
accordance with Section 14 hereof, (iii) after receipt of such certificates or
depositary receipts, cause the same to be



                                      11
<PAGE>
 
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) after receipt thereof, deliver such cash, if any, 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 pursuant to Section 11(a)(iii)
hereof) shall 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 (including Common Stock) of the Company, pay cash and/or
distribute other property pursuant to Section 11(a) hereof, the Company will
make all arrangements necessary so that such other securities, cash and/or other
property are available for distribution by the Rights Agent, if and when
appropriate. The Company reserves the right to require prior to the occurrence
of a Triggering Event that, upon any exercise of Rights, a number of Rights be
exercised so that only whole shares of Preferred Stock would be issued.

       (d) In case the registered holder of any Rights Certificate shall
exercise less than all the Rights evidenced thereby, a new Rights Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent and 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, 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 Section 11(a)(ii) 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, 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 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),
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



                                      12
<PAGE>
 
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 other Person as a result of its failure to make any determinations with
respect to an Acquiring Person or its Affiliates, Associates or transferees
hereunder.

       (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
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 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 CAPITAL STOCK.

       (a) The Company covenants and agrees that it will cause to be reserved
and kept available out of its authorized and unissued shares of Preferred Stock
(and, following the occurrence of a Triggering Event, out of its authorized and
unissued shares of Common Stock and/or other securities or out of its authorized
and issued shares held in its treasury), the number of shares of Preferred Stock
(and, following the occurrence of a Triggering Event, Common Stock and/or other
securities) that, as provided in this Agreement, including Section 11(a)(iii)
hereof,



                                      13
<PAGE>
 
will be sufficient to permit the exercise in full of all outstanding Rights.

       (b)  So long as the shares of Preferred Stock (and, following
the occurrence of a Triggering Event, Common Stock and/or other
securities) issuable and deliverable upon the exercise of the Rights may
be listed on any national securities exchange, the Company shall use its
best efforts to cause, from and after such time as the Rights become
exercisable, all shares reserved for such issuance to be listed 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 Section 11(a)(ii) Event on which the consideration to be delivered by
the Company upon exercise of the Rights has been determined in accordance
with Section 11(a)(iii) hereof, a registration statement under the
Securities Act of 1933 (the "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
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 the expiration
of the Rights.  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.  The Company may temporarily suspend, for a period of time 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 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.  In addition, if the Company shall
determine that a registration statement is required following the
Distribution Date, the Company may temporarily suspend the exercisability
of the Rights until such time as a registration statement has been
declared effective.  Notwithstanding any provision of this Agreement to
the contrary, the Rights shall not be exercisable in any jurisdiction if
the requisite qualification in such jurisdiction shall not have been
obtained, the exercise thereof shall not be permitted under applicable law
or a registration statement shall not have been declared effective.



                                      14
<PAGE>
 
       (d) The Company covenants and agrees that it will take all such action as
may be necessary to ensure that all one one-thousandths of a share of Preferred
Stock (and, following the occurrence of a Triggering Event, Common Stock and/or
other securities) delivered upon exercise of Rights shall, at the time of
delivery of the certificates for such shares (subject to payment of the Purchase
Price), be duly and validly authorized and issued and fully paid and
nonassessable.

       (e) The Company further covenants and agrees that it will pay when due
and payable any and all federal and state transfer taxes and charges which may
be payable in respect of the issuance or delivery of the Rights Certificates and
of any certificates for a number of one one-thousandths of a share of Preferred
Stock (or Common Stock and/or other securities, as the case may be) 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 a
number of one one-thousandths of a share of Preferred Stock (or Common Stock
and/or other securities, as the case may be) in respect of a name other than
that of, the registered holder of the Rights Certificates evidencing Rights
surrendered for exercise or to issue or deliver any certificates for a number of
one one-thousandths of a share of Preferred Stock (or Common Stock and/or other
securities, as the case may be) in a name other than that of the registered
holder upon the exercise of any Rights until 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 STOCK RECORD DATE.  Each Person in whose
name any certificate for a number of one one-thousandths of a share of
Preferred Stock (or Common Stock and/or other securities, as the case may
be) is issued upon the exercise of Rights shall for all purposes be deemed
to have become the holder of record of such fractional shares of Preferred
Stock (or Common Stock and/or other securities, as the case may be)
represented thereby on, and such certificate shall be dated, the date upon
which the Rights Certificate evidencing such Rights was duly surrendered
and payment of the Purchase Price (and all applicable transfer taxes) was
made; PROVIDED, HOWEVER, that if the date of such surrender and payment is
a date upon which the Preferred Stock (or Common Stock and/or other
securities, as the case may be) transfer books of the Company are closed,
such Person shall be deemed to have become the record holder of such
shares (fractional or otherwise) on, and such certificate shall be dated,



                                      15
<PAGE>
 
the next succeeding Business Day on which the Preferred Stock (or Common
Stock and/or other securities, as the case may be) 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 stockholder of the Company with respect to 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 AND KIND OF
SHARES OR NUMBER OF RIGHTS.  The Purchase Price, the number and kind of
shares covered by each Right and the number of Rights outstanding are
subject to adjustment from time to time as provided in this Section 11.

       (a)  (i)  In the event the Company shall at any time after
the date of this Agreement (A) declare a dividend on the Preferred Stock
payable in shares of Preferred Stock, (B) subdivide the outstanding
Preferred Stock, (C) combine the outstanding Preferred Stock into a
smaller number of shares, or (D) issue any shares of its capital stock in
a reclassification of the Preferred Stock (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), except as otherwise
provided in this Section 11(a) and Section 7(e) hereof, the Purchase Price
in effect at the time of the record date for such dividend or of the
effective date of such subdivision, combination or reclassification, and
the number and kind of shares of Preferred Stock or capital stock, as the
case may be, issuable on such date, shall be proportionately adjusted so
that the holder of any Right exercised after such time shall be entitled
to receive, upon payment of the Purchase Price then in effect, the
aggregate number and kind of shares of Preferred Stock or capital stock,
as the case may be, which, if such Right had been exercised immediately
prior to such date and at a time when the Preferred Stock transfer books
of the Company were open, such holder would have owned upon such exercise
and been entitled to receive by virtue of such dividend, subdivision,
combination or reclassification.  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.



                                      16
<PAGE>
 
          (ii) In the event any Person (other than an Exempted
Person, the Company, any Subsidiary of the Company, any employee benefit
plan of the Company or of any Subsidiary of the Company, or any Person
organized, appointed or established by the Company for or pursuant to the
terms of any such plan), alone or together with its Affiliates and
Associates, shall, at any time after the Rights Dividend Declaration Date,
become the Beneficial Owner of 20% or more of the shares of Common Stock
then outstanding, unless the event causing the 20% threshold to be crossed
is a transaction set forth in Section 13(a) hereof or is an acquisition of
shares of Common Stock pursuant to a tender offer or an exchange offer for
all outstanding shares of Common Stock at a price and on terms determined
by at least a majority of the members of the Board of Directors of the
Company who are not officers of the Company and who are not
representatives, nominees, Affiliates or Associates of an Acquiring
Person, after receiving advice from one or more investment banking firms,
to be (a) at a price which is fair to stockholders (taking into account
all factors which such members of the Board deem relevant, including,
without limitation, prices which could reasonably be achieved if the
Company or its assets were sold on an orderly basis designed to realize
maximum value) and (b) otherwise in the best interests of the Company and
its stockholders, then, promptly following the occurrence of such event,
proper provision shall be made so that each holder of a Right (except as
provided below and in Section 7(e) hereof) shall thereafter have the right
to receive, upon exercise thereof at the then current Purchase Price in
accordance with the terms of this Agreement, in lieu of a number of one
one-thousandths of a share of Preferred Stock, such number of shares of
Common Stock of the Company as shall equal the result obtained by (x)
multiplying the then current Purchase Price by the then number of one one-
thousandths of a share of Preferred Stock for which a Right was exercisable
immediately prior to the first occurrence of a Section 11(a)(ii) Event, and (y)
dividing that product (which, following such first occurrence, shall thereafter
be referred to as the "Purchase Price" for each Right and for all purposes of
this Agreement) by 25% of the current market price (determined pursuant to
Section 11(d) hereof) per share of Common Stock on the date of such first
occurrence (such number of shares, the "Adjustment Shares").

          (iii) In the event that the number of shares of Common Stock which are
authorized by the Company's Certificate of Incorporation but not outstanding or
reserved for issuance for purposes other than upon exercise of the Rights are
not sufficient to permit the exercise in full of the Rights in accordance with
the foregoing subparagraph (ii) of this Section 11(a), the Company shall (A)
determine the value of the Adjustment



                                      17
<PAGE>
 
Shares issuable upon the exercise of a Right (the "Current Value"), and (B) with
respect to each Right (subject to Section 7(e) hereof), make adequate provision
to substitute for the Adjustment Shares, upon the exercise of a Right and
payment of the applicable Purchase Price, (1) cash, (2) a reduction in the
Purchase Price, (3) Common Stock or other equity securities of the Company
(including, without limitation, shares, or units of shares, of preferred stock,
such as the Preferred Stock, which the Board of Directors of the Company has
deemed to have essentially the same value or economic rights as shares of Common
Stock (such shares of preferred stock being referred to as "Common Stock
Equivalents")), (4) debt securities of the Company, (5) other assets, or (6) any
combination of the foregoing, having an aggregate value equal to the Current
Value (less the amount of any reduction in the Purchase Price), where such
aggregate value has been determined by the Board based upon the advice of a
nationally recognized investment banking firm selected by the Board; PROVIDED,
HOWEVER, that 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 Section 11(a)(ii) Event and (y) the date on
which the Company's right of redemption pursuant to Section 23(a) expires (the
later of (x) and (y) being referred to herein as the "Section 11(a)(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, shares
of Common Stock (to the extent available) and then, if necessary, cash, which
shares and/or cash have an aggregate value equal to the Spread. For purposes of
the preceding sentence, the term "Spread" shall mean the excess of (i) the
Current Value over (ii) the Purchase Price. If the Board of Directors of the
Company determines in good faith that it is likely that sufficient additional
shares of Common Stock could be authorized for issuance upon exercise in full of
the Rights, the thirty-day period set forth above may be extended to the extent
necessary, but not more than ninety (90) days after the Section 11(a)(ii)
Trigger Date, in order that the Company may seek stockholder approval for the
authorization of such additional shares (such thirty-day period, as it may be
extended, is herein called the "Substitution Period"). To the extent that action
is to be taken pursuant to the first and/or third sentences of this Section
11(a)(iii), the Company (1) shall provide, subject to Section 7(e) hereof, that
such action shall apply uniformly to all outstanding Rights, and (2) may suspend
the exercisability of the Rights until the expiration of the Substitution Period
in order to seek such stockholder approval for such authorization of additional
shares and/or to decide the appropriate form of distribution to be made pursuant
to such first sentence and to determine the value thereof. In the event of any
such



                                      18
<PAGE>
 
suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a
public announcement at such time as the suspension is no longer in effect.
For purposes of this Section 11(a)(iii), the value of each Adjustment
Share shall be the Current Market Price per share of the Common Stock on
the Section 11(a)(ii) Trigger Date and the per share or per unit value of
any Common Stock Equivalent shall be deemed to equal the Current Market
Price per share of the Common Stock on such date.

       (b) In case the Company shall fix a record date for the issuance of
rights, options or warrants to all holders of Preferred Stock entitling them to
subscribe for or purchase (for a period expiring within forty-five (45) calendar
days after such record date) Preferred Stock (or shares having the same rights,
privileges and preferences as the shares of Preferred Stock ("equivalent
preferred stock")) or securities convertible into Preferred Stock or equivalent
preferred stock at a price per share of Preferred Stock or per share of
equivalent preferred stock (or having a conversion price per share, if a
security convertible into Preferred Stock or equivalent preferred stock) less
than the current market price (as determined pursuant to Section 11(d) hereof)
per share of Preferred Stock on such record date, the Purchase Price to be in
effect after such record date shall be determined by multiplying the Purchase
Price in effect immediately prior to such record date by a fraction, the
numerator of which shall be the number of shares of Preferred Stock outstanding
on such record date, plus the number of shares of Preferred Stock which the
aggregate offering price of the total number of shares of Preferred Stock and/or
equivalent preferred stock so to be offered (and/or the aggregate initial
conversion price of the convertible securities so to be offered) would purchase
at such current market price, and the denominator of which shall be the number
of shares of Preferred Stock outstanding on such record date, plus the number of
additional shares of Preferred Stock and/or equivalent preferred stock to be
offered for subscription or purchase (or into which the convertible securities
so to be offered are initially convertible). In case such subscription price may
be paid by delivery of consideration part or all of which may 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. Shares of Preferred Stock owned by or held
for the account of the Company shall not be deemed outstanding for the purpose
of any such computation. Such adjustment



                                      19
<PAGE>
 
shall be made successively whenever such a record date is fixed, and in
the event that such rights or warrants are not so issued, the Purchase
Price shall be adjusted to be the Purchase Price which would then be in
effect if such record date had not been fixed.

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

       (d)  (i)  For the purpose of any computation hereunder, other
than computations made pursuant to Section 11(a)(iii) hereof, the Current
Market Price per share of Common Stock on any date shall be deemed to be
the average of the daily closing prices per share of such Common Stock for
the thirty (30)consecutive Trading Days immediately prior to such date,
and for purposes of computations made pursuant to Section 11(a)(iii)
hereof, the Current Market Price per share of Common Stock on any date
shall be deemed to be the average of the daily closing prices per share of
such Common Stock for the ten (10) consecutive Trading Days immediately
following such date; PROVIDED, HOWEVER, that in the event that the Current
Market Price per share of the Common Stock is determined during a period
following the announcement by the issuer of such Common Stock of (A) a



                                      20
<PAGE>
 
dividend or distribution on such Common Stock payable in shares of such
Common Stock or securities convertible into shares of such Common Stock
(other than the Rights), or (B) any subdivision, combination or
reclassification of such Common Stock, and the ex-dividend date for such
dividend or distribution, or the record date for such subdivision,
combination or reclassification shall not have occurred prior to the
commencement of the requisite thirty (30) Trading Day or ten (10) Trading
Day period, as set forth above, then, and in each such case, the Current
Market Price shall be properly adjusted to take into account ex-dividend
trading.  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 shares of Common Stock are not listed or admitted to
trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which the shares
of Common Stock are listed or admitted to trading or, if the shares of
Common Stock are not listed or admitted to trading on any national
securities exchange, the last quoted price or, if not so quoted, the
average of the high bid and low asked prices in the over-the-counter
market, as reported by the National Association of Securities Dealers,
Inc. Automated Quotation System ("NASDAQ") or such other system then in
use, or, if on any such date the shares of Common Stock are not quoted by
any such organization, the average of the closing bid and asked prices as
furnished by a professional market maker making a market in the Common
Stock selected by the Board of Directors of the Company.  If on any such
date no market maker is making a market in the Common Stock, the fair
value of such shares on such date as determined in good faith by the Board
shall be used.  The term "Trading Day" shall mean a day on which the
principal national securities exchange on which the shares of Common Stock
are listed or admitted to trading is open for the transaction of business
or, if the shares of Common Stock are not listed or admitted to trading on
any national securities exchange, a Business Day.  If the Common Stock is
not publicly held or not so listed or traded, Current Market Price per
share shall mean the fair value per share as determined in good faith by
the Board, whose determination shall be described in a statement filed
with the Rights Agent and shall be conclusive for all purposes.



                                      21
<PAGE>
 
          (ii)  For the purpose of any computation hereunder, the
Current Market Price per share of Preferred Stock shall be determined in
the same manner as set forth above for the Common Stock in clause (i) of
this Section 11(d) (other than the last sentence thereof).  If the Current
Market Price per share of Preferred Stock cannot be determined in the
manner provided above or if the Preferred Stock is not publicly held or
listed or traded in a manner described in clause (i) of this Section
11(d), the Current Market Price per share of Preferred Stock shall be
conclusively deemed to be an amount equal to 1,000 (as such number may be
appropriately adjusted for such events as stock splits, stock dividends
and recapitalizations with respect to the Common Stock occurring after the
date of this Agreement) multiplied by the Current Market Price per share
of the Common Stock.  If neither the Common Stock nor the Preferred Stock
is publicly held or so listed or traded, Current Market Price per share of
the Preferred Stock shall mean the fair value per share as determined in
good faith by the Board of Directors of the Company, whose determination
shall be described in a statement filed with the Rights Agent and shall be
conclusive for all purposes.  For all purposes of this Agreement, the
Current Market Price of a Unit shall be equal to the Current Market Price
of one share of Preferred Stock divided by 1,000.

       (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 share of Common Stock or other share or one-ten millionth
of a share of Preferred Stock, as the case may be.  Notwithstanding the
first sentence of this Section 11(e), any adjustment required by this
Section 11 shall be made no later than the earlier of (i) three (3) years
from the date of the transaction which mandates such adjustment, or (ii)
the Expiration Date.

       (f)  If as a result of an adjustment made pursuant to Section
11(a)(ii) or Section 13(a) hereof, the holder of any Right thereafter
exercised shall become entitled to receive any shares of capital stock
other than Preferred Stock, thereafter the number of such other shares so
receivable upon exercise of any Right and the Purchase Price thereof shall
be subject to adjustment from time to time in a manner and on terms as
nearly equivalent as practicable to the provisions with respect to the
Preferred Stock contained in Sections 11(a), (b), (c), (e), (g), (h), (i),



                                      22
<PAGE>
 
(j), (k) and (m), and the provisions of Sections 7, 9, 10, 13 and 14
hereof with respect to the Preferred Stock shall apply on like terms to
any such other shares.

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

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

       (i) The Company may elect on or after the date of any adjustment of the
Purchase Price to adjust the number of Rights, in lieu of any adjustment in the
number of one one-thousandths of a share of Preferred Stock purchasable upon the
exercise of a Right. Each of the Rights outstanding after the adjustment in the
number of Rights shall be exercisable for the number of one one-thousandths of a
share of Preferred Stock for which a Right was exercisable immediately prior to
such adjustment. Each Right held of record prior to such adjustment of the
number of Rights shall become that number of Rights (calculated to the nearest
one ten-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


                                      23
<PAGE>
 
Company shall, as promptly as practicable, cause to be distributed to
holders of record of Rights Certificates on such record date Rights
Certificates evidencing, subject to Section 14 hereof, the additional
Rights to which such holders shall be entitled as a result of such
adjustment, or, at the option of the Company, shall cause to be
distributed to such holders of record in substitution and replacement for
the Rights Certificates held by such holders prior to the date of
adjustment, and upon surrender thereof, if required by the Company, new
Rights Certificates evidencing all the Rights to which such holders shall
be entitled after such adjustment.  Rights Certificates 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 one one-thousandths of a share of Preferred Stock issuable upon the
exercise of the Rights, the Rights Certificates theretofore and thereafter
issued may continue to express the Purchase Price per one one-thousandth of a
share and the number of one one-thousandths of a 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 then stated value, if any, of the
number of one one-thousandths of a share of Preferred Stock issuable upon
exercise of the Rights, the Company shall take any corporate action which
may, in the opinion of its counsel, be necessary in order that the Company
may validly and legally issue fully paid and nonassessable such number of
one one-thousandths of a share of Preferred Stock at such adjusted
Purchase Price.

       (l) In any case in which this Section 11 shall require that an adjustment
in the Purchase Price be made effective as of a record date for a specified
event, the Company may elect to defer until the occurrence of such event the
issuance to the holder of any Right exercised after such record date the number
of one one-thousandths of a share of Preferred Stock and other capital stock or
securities of the Company, if any, issuable upon such exercise over and above
the number of one one-thousandths of a share of Preferred Stock and other
capital stock or securities of the Company, if any, issuable upon such exercise
on the basis of the Purchase Price in effect prior to such adjustment; PROVIDED,
HOWEVER, that the Company shall deliver to such holder a due bill or other



                                      24
<PAGE>
 
appropriate instrument evidencing such holder's right to receive such
additional shares (fractional or otherwise) or securities upon the
occurrence of the event requiring such adjustment.

       (m) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that in their good faith judgment the Board of Directors of the
Company shall determine to be advisable in order that any (i) consolidation or
subdivision of the Preferred Stock, (ii) issuance wholly for cash of any shares
of Preferred Stock at less than the current market price, (iii) issuance wholly
for cash of shares of Preferred Stock or securities which by their terms are
convertible into or exchangeable for shares of Preferred Stock, (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 Stock
shall not be taxable to such stockholders.

       (n)  The Company covenants and agrees that it shall not, at
any time after the Distribution Date, (i) consolidate with any other
Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), (ii) merge with or into any other
Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), or (iii) sell or transfer (or permit
any Subsidiary to sell or transfer), in one transaction, or a series of
related transactions, assets or earning power aggregating more than 50% of
the assets or earning power of the Company and its Subsidiaries (taken as
a whole) to any other Person or Persons (other than the Company and/or any
of its Subsidiaries in one or more transactions each of which complies
with Section 11(o) hereof), if (x) at the time of or immediately after
such consolidation, merger or sale there are any rights, warrants or other
instruments or securities outstanding or agreements in effect which would
substantially diminish or otherwise eliminate the benefits intended to be
afforded by the Rights or (y) prior to, simultaneously with or immediately
after such consolidation, merger or sale, the stockholders of the Person
who constitutes, or would constitute, the "Principal Party" for purposes
of Section 13(a) 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 Section 23 or



                                      25
<PAGE>
 
Section 26 hereof, take (or permit any Subsidiary to take) any action if
at the time such action is taken it is reasonably foreseeable that such
action will diminish substantially or otherwise eliminate the benefits
intended to be afforded by the Rights.

       (p) Anything in this Agreement to the contrary notwithstanding, in the
event that the Company shall at any time after the Rights Dividend Declaration
Date and prior to the Distribution Date (i) declare a dividend on the
outstanding shares of Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding shares of Common Stock, or (iii) combine the
outstanding shares of Common Stock into a smaller number of shares, the number
of Rights associated with each share of Common Stock then outstanding, or issued
or delivered thereafter but prior to the Distribution Date, shall be
proportionately adjusted so that the number of Rights thereafter associated with
each share of Common Stock following any such event shall equal the result
obtained by multiplying the number of Rights associated with each share of
Common Stock immediately prior to such event by a fraction the numerator which
shall be the total number of shares of Common Stock outstanding immediately
prior to the occurrence of the event and the denominator of which shall be the
total number of shares of Common Stock outstanding immediately following the
occurrence of such event.

    Section 12.  CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF
SHARES.  Whenever an adjustment is made as provided in Section 11 and
Section 13 hereof, the Company shall (a) promptly prepare a certificate
setting forth such adjustment and a brief statement of the facts
accounting for such adjustment, (b) promptly file with the Rights Agent,
and with each transfer agent for the Preferred Stock and the Common Stock,
a copy of such certificate, and (c) mail a brief summary thereof to each
holder of a Rights Certificate (or, if prior to the Distribution Date, to
each holder of a certificate representing shares of Common Stock) in
accordance with Section 25 hereof.  The Rights Agent shall be fully
protected in relying on any such certificate and on any adjustment therein
contained.

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

       (a)  In the event that, following the Stock Acquisition Date,
directly or indirectly, (x) the Company shall consolidate with, or merge
with and into, any other Person (other than a Subsidiary of the Company in
a transaction which complies with Section 11(o) hereof), and the Company



                                      26
<PAGE>
 
shall not be the continuing or surviving corporation of such consolidation or
merger, (y) any Person (other than a Subsidiary of the Company in a transaction
which complies with Section 11(o) hereof) shall consolidate with, or merge with
or into, the Company, and the Company shall be the continuing or surviving
corporation of such consolidation or merger and, in connection with such
consolidation or merger, all or part of the outstanding shares of Common Stock
shall be changed into or exchanged for stock or other securities of any other
Person or cash or any other property, or (z) the Company shall sell or otherwise
transfer (or one or more of its Subsidiaries shall sell or otherwise transfer),
in one transaction or a series of related transactions, assets or earning power
aggregating more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any Person or Persons (other than the Company
or any Subsidiary of the Company in one or more transactions each of which
complies with Section 11(o) hereof), then, and in each such case (except as may
be contemplated by Section 13(d) hereof), proper provision shall be made so
that: (i) each holder of a Right, except as provided in Section 7(e) hereof,
shall thereafter have the right to receive, upon the exercise thereof at the
then current Purchase Price in accordance with the terms of this Agreement, such
number of validly authorized and issued, fully paid, non-assessable and freely
tradeable shares of Common Stock of the Principal Party (as such term is
hereinafter defined), not subject to any liens, encumbrances, rights of first
refusal or other adverse claims, as shall be equal to the result obtained by (1)
multiplying the then current Purchase Price by the number of one one-thousandths
of a share of Preferred Stock for which a Right is exercisable immediately prior
to the first occurrence of a Section 13 Event (or, if a Section 11(a)(ii) Event
has occurred prior to the first occurrence of a Section 13 Event, multiplying
the number of such one one-thousandths of a share for which a Right was
exercisable immediately prior to the first occurrence of a Section 11(a)(ii)
Event by the Purchase Price in effect immediately prior to such first
occurrence), and dividing that product (which, following the first occurrence of
a Section 13 Event, shall be referred to as the "Purchase Price" for each Right
and for all purposes of this Agreement) by (2) 25% of the current market price
(determined pursuant to Section 11(d)(i) hereof) per share of the Common Stock
of such Principal Party on the date of consummation of such Section 13 Event;
(ii) such Principal Party shall thereafter be liable for, and



                                      27
<PAGE>
 
shall assume, by virtue of such Section 13 Event, all the obligations and
duties of the Company pursuant to this Agreement; (iii) the term "Company"
shall 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; (iv) such Principal Party shall take such steps (including, but
not limited to, the reservation of a sufficient number of shares of its
Common Stock) in connection with the consummation of any such transaction
as may be necessary to assure that the provisions hereof shall thereafter
be applicable, as nearly as reasonably may be, in relation to its shares
of Common Stock thereafter deliverable upon the exercise of the Rights;
and (v) the provisions of Section 11(a)(ii) hereof shall be of no effect
following the first occurrence of any Section 13 Event.

       (b)  "Principal Party" shall mean:

            (i) in the case of any transaction described in clause (x) or (y) of
the first sentence of Section 13(a), the Person that is the issuer of any
securities into which shares of Common Stock of the Company are converted in
such merger or consolidation, and if no securities are so issued, the Person
that is the other party to such merger or consolidation; and

            (ii) in the case of any transaction described in clause (z) of the
first sentence of Section 13(a), the Person that is the party receiving the
greatest portion of the assets or earning power transferred pursuant to such
transaction or transactions; PROVIDED, HOWEVER, that in any such case, (1) if
the Common Stock of such Person is not at such time and has not been
continuously over the preceding twelve-month period registered under Section 12
of the Exchange Act, and such Person is a direct or indirect Subsidiary of
another Person the Common Stock of which is and has been so registered,
"Principal Party" shall refer to such other Person; and (2) in case such Person
is a Subsidiary, directly or indirectly, of more than one Person, the Common
Stocks of two or more of which are and have been so registered, "Principal
Party" shall refer to whichever of such Persons is the issuer of the Common
Stock having the greatest aggregate market value.

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



                                      28
<PAGE>
 
soon as practicable after the date of any consolidation, merger or sale of
assets mentioned in paragraph (a) of this Section 13, the Principal Party
will:

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

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

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

       (d)  Notwithstanding anything in this Agreement to the
contrary, Section 13 shall not be applicable to a transaction described in
subparagraphs (x) and (y) of Section 13(a) if (i) such transaction is
consummated with a Person or Persons who acquired shares of Common Stock
pursuant to a tender offer or exchange offer for all outstanding shares of
Common Stock which complies with the provisions of Section 11(a)(ii)(B)
hereof (or a wholly owned Subsidiary of any such Person or Persons), (ii)
the price per share of Common Stock offered in such transaction is not
less than the price per share of Common Stock paid to all holders of
shares of Common Stock whose shares were purchased pursuant to such tender
offer or exchange offer and (iii) the form of consideration being offered
to the remaining holders of shares of Common Stock pursuant to such
transaction is the same as the form of consideration paid pursuant to such
tender offer or exchange offer.  Upon consummation of any such transaction
contemplated by this Section 13(d), all Rights hereunder shall expire.

    Section 14.  FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

    (a) The Company shall not be required to issue fractions of Rights, except
prior to the Distribution Date as provided in Section 11(p)



                                      29
<PAGE>
 
hereof, 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
purposes of this Section 14(a), the current market value of a whole Right
shall be the closing price of the Rights for the Trading Day immediately
prior to the date on which such fractional Rights would have been
otherwise issuable.  The closing price of the Rights for any day shall be
the last sale price, regular way, or, in case no such sale takes place on
such day, the average of the closing bid and asked prices, regular way, in
either case as reported in the principal consolidated transaction
reporting system with respect to securities listed or admitted to trading
on the New York Stock Exchange or, if the Rights are not listed or
admitted to trading on the New York Stock Exchange, as reported in the
principal consolidated transaction reporting system with respect to
securities listed on the principal national securities exchange on which
the Rights are listed or admitted to trading, or if the Rights are not
listed or admitted to trading on any national securities exchange, the
last quoted price or, if not so quoted, the average of the high bid and
low asked prices in the over-the-counter market, as reported by NASDAQ or
such other system then in use or, if on any such date the Rights are not
quoted by any such organization, the average of the closing bid and asked
prices as furnished by a professional market maker making a market in the
Rights selected by the Board of Directors of the Company.  If on any such
date no such market maker is making a market in the Rights the fair value
of the Rights on such date as determined in good faith by the Board of
Directors of the Company shall be used.

       (b)  The Company shall not be required to issue fractions of
shares of Preferred Stock (other than fractions which are integral
multiples of one one-thousandth of a share of Preferred Stock) upon
exercise of the Rights or to distribute certificates which evidence
fractional shares of Preferred Stock (other than fractions which are
integral multiples of one one-thousandth of a share of Preferred Stock).
In lieu of fractional shares of Preferred Stock that are not integral
multiples of one one-thousandth of a share of Preferred Stock, the Company
may pay to the registered holders of Rights Certificates at the time such
Rights are exercised as herein provided an amount in cash equal to the
same fraction of the current market value of one one-thousandth of a share
of Preferred Stock.  For purposes of this Section 14(b), the current



                                      30
<PAGE>
 
market value of one one-thousandth of a share of Preferred Stock shall be
one one-thousandth of the closing price of a share of Preferred Stock
(as determined pursuant to Section 11(d)(ii) hereof) for the Trading Day
immediately prior to the date of such exercise.

       (c) Following the occurrence of a Triggering Event, the Company shall not
be required to issue fractions of shares of Common Stock upon exercise of the
Rights or to distribute certificates which evidence fractional shares of Common
Stock. In lieu of fractional shares of Common Stock, the Company may pay to the
registered holders of Rights Certificates at the time such Rights are exercised
as herein provided an amount in cash equal to the same fraction of the current
market value of one (1) share of Common Stock. For purposes of this Section
14(c), the current market value of one (1) share of Common Stock shall be the
closing price of one (1) share of Common Stock (as determined pursuant to
Section 11(d)(i) hereof) for the Trading Day immediately prior to the date of
such exercise.

       (d) The holder of a Right by the acceptance of the Rights expressly
waives his or her right to receive any fractional Rights or any fractional
shares upon exercise of a Right, except as permitted by this Section 14.

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



                                      31

    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 Common Stock;

       (b)  after the Distribution Date, the Rights Certificates are
transferable only on the registry books of the Rights Agent if surrendered
at the 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;

       (c) subject to Section 6(a) and Section 7(f) hereof, the Company and the
Rights Agent may deem and treat the Person in whose name a Rights Certificate
(or, prior to the Distribution Date, the associated Common Stock certificate) is
registered as the absolute owner thereof and of the Rights evidenced thereby
(notwithstanding any notations of ownership or writing on the Rights
Certificates or the associated Common Stock certificate made by anyone other
than the Company or the Rights Agent) for all purposes whatsoever, and neither
the Company nor the Rights Agent, subject to the last sentence of Section 7(e)
hereof, shall be required to be affected by any notice to the contrary; and

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

    Section 17.  RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER.
No holder, as such, of any Rights Certificate shall be entitled to vote,
receive dividends or be deemed for any purpose the holder of the number of
one one-thousandths of a share of Preferred Stock or any other securities
of the Company which may at any time be issuable on the exercise of the
Rights represented thereby, nor shall anything contained herein or in any



                                      32
<PAGE>
 
Rights Certificate be construed to confer upon the holder of any Rights
Certificate, as such, any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action, or to receive notice of meetings or other actions affecting
stockholders (except as provided in Section 24 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 disbursements and
other disbursements incurred in the administration and execution of this
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless against,
any loss, liability, or expense, incurred without gross negligence, bad faith or
willful misconduct on the part of the Rights Agent, for anything done or omitted
by the Rights Agent in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim of
liability in the premises.

       (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 Common Stock or for other securities of the Company, instrument
of assignment or transfer, power of attorney, endorsement, affidavit, letter,
notice, direction, consent, certificate, statement, or other paper or document
believed by it to be genuine and to be signed, executed and, where necessary,
verified or acknowledged, by the proper Person or Persons.

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

       (a) Any corporation into which the Rights Agent or any successor Rights
Agent may be merged or with which it may be consolidated, or any corporation
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any corporation succeeding to the
corporate trust or shareholder services



                                      33
<PAGE>
 
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 a 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 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 advice 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 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



                                      34
<PAGE>
 
thereof be herein specifically prescribed) may be deemed to be conclusively
proved and established by a certificate signed by the Chairman of the Board, the
Vice Chairman, the President, any Vice President, the Treasurer, any Assistant
Treasurer, the Secretary or any Assistant Secretary of the Company and delivered
to the Rights Agent; and such certificate shall be full authorization to the
Rights Agent for any action taken or suffered in good faith by it under the
provisions of this Agreement in reliance upon such certificate.

       (c) The Rights Agent shall be liable hereunder only for its own gross
negligence, bad faith or willful misconduct.

       (d)  The Rights Agent shall not be liable for or by reason of
any of the statements of fact or recitals contained in this Agreement or
in the Rights Certificates or be required to verify the same (except as to
its countersignature on such Rights Certificates), 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 adjustment
required under the provisions of Section 11 or Section 13 hereof or
responsible for the manner, method or amount of any such adjustment or the
ascertaining of the existence of facts that would require any such
adjustment (except with respect to the exercise of Rights evidenced by
Rights Certificates after actual notice of any such adjustment); nor shall
it by any act hereunder be deemed to make any representation or warranty
as to the authorization or reservation of any shares of Common Stock or
Preferred Stock to be issued pursuant to this Agreement or any Rights
Certificate or as to whether any shares of Common Stock or Preferred Stock
will, when so 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.



                                      35
<PAGE>
 
       (g)  The Rights Agent is hereby authorized and directed to
accept instructions with respect to the performance of its duties
hereunder from the Chairman of the Board, the Vice Chairman, the
President, any Vice President, the Secretary, any Assistant Secretary, the
Treasurer or any Assistant Treasurer of the Company, and to apply to such
officers for advice or instructions in connection with its duties, and it
shall not be liable for any action taken or suffered to be taken by it in
good faith in accordance with instructions of any such officer.

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

       (i)  The Rights Agent may execute and exercise any of the
rights or powers hereby vested in it or perform any duty hereunder either
itself or by or through its attorneys or agents, and the Rights Agent
shall not be answerable or accountable for any act, default, neglect or
misconduct of any such attorneys or agents or for any loss to the Company
resulting from any such act, default, neglect or misconduct; PROVIDED,
HOWEVER, 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 of transfer without first
consulting with the Company.



                                      36

    Section 21.  CHANGE OF RIGHTS AGENT.  The Rights Agent or any
successor Rights Agent may resign and be discharged from its duties under
this Agreement upon thirty (30) days' notice in writing mailed to the
Company, and to each transfer agent of the Common Stock and Preferred
Stock, by registered or certified mail, and to the holders of the Rights
Certificates by first-class mail.  The Company may, in its sole
discretion, remove the Rights Agent or any successor Rights Agent upon
thirty (30) days' notice in writing, mailed to the Rights Agent or
successor Rights Agent, as the case may be, and to each transfer agent of
the Common Stock and Preferred Stock, 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 Rights Certificate
for inspection by the Company), then any 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 corporate trust 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
$100,000,000.  After appointment, the successor Rights Agent shall be
vested with the same powers, rights, duties and responsibilities as if it
had been originally named as Rights Agent without further act or deed; but
the predecessor Rights Agent shall deliver and transfer to the successor
Rights Agent any property at the time held by it hereunder, and execute
and deliver any further assurance, conveyance, act or deed necessary for
the purpose.  Not later than the effective date of any such appointment,
the Company shall file notice thereof in writing with the predecessor
Rights Agent and each transfer agent of the Common Stock and the Preferred
Stock, and mail a notice thereof in writing to the registered holders of
the Rights Certificates.  Failure to give any notice provided for in this
Section 21, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the
appointment of the successor Rights Agent, as the case may be.

    Section 22.  ISSUANCE OF NEW RIGHTS CERTIFICATES.  Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Rights Certificates evidencing Rights in such form
as may be approved by its Board of Directors to reflect any adjustment or change
in the Purchase Price and the number or kind or class of shares or other
securities or property purchasable under the Rights Certificates made in
accordance with the provisions of this Agreement. In addition, in connection
with the issuance or sale of shares of Common Stock following the Distribution
Date and prior to the redemption or expiration of the Rights, the Company (a)
shall, with respect to shares of Common Stock so issued or sold pursuant to the
exercise of stock options or under any employee plan or arrangement, granted or
awarded as of the Distribution Date, 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 if, and to the extent that, the Company shall
be advised by counsel that such issuance would create a significant risk of
material adverse tax consequences to the Company or the Person to whom such
Rights Certificate would be issued, and (ii) no such Rights Certificate shall be
issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

    Section 23.  REDEMPTION AND TERMINATION.

       (a) The Board of Directors of the Company may, at its option, at any time
prior to the earlier of (i) the close of business on the twentieth day following
the Stock Acquisition Date (or, if the Stock Acquisition Date shall have
occurred prior to the Record Date, the close of business on the twentieth day
following the Record Date), or (ii) the Final Expiration Date, redeem all but
not less than all the then outstanding Rights at a redemption price of $0.001
per Right, as such amount may be appropriately adjusted to reflect any stock
split, stock dividend or similar transaction occurring after the date hereof
(such redemption price being hereinafter referred to as the "Redemption Price");
PROVIDED, HOWEVER, if the Board of Directors of the Company authorizes
redemption of the Rights in either of the circumstances set forth in clauses (i)
and (ii) below, then there must be Continuing Directors then in office and such
authorization shall require the concurrence of a majority of such Continuing
Directors: (i) such authorization occurs on or after the time a Person becomes
an Acquiring Person, or (ii) such


                                      38
<PAGE>
 
authorization occurs on or after the date of a change (resulting from a proxy or
consent solicitation or an action by written consent of stockholders, whether or
not made pursuant to, and in accordance with, the applicable provisions of the
General Rules and Regulations under the Exchange Act) in a majority of the
directors in office at the commencement of such solicitation, or prior to such
written consent, if any Person who is a participant in such solicitation, or who
signed such consent, has stated (or, if upon the commencement of such
solicitation, a majority of the Board of Directors of the Company has determined
in good faith) that such Person (or any of its Affiliates or Associates) intends
to take, or may consider taking, any action which would result in such Person
becoming an Acquiring Person or which would cause the occurrence of a Triggering
Event unless, concurrent with such solicitation, such Person (or one or more of
its Affiliates or Associates) is making a cash tender offer pursuant to a
Schedule 14D-1 (or any successor form) filed with the Securities and Exchange
Commission for all outstanding shares of Common Stock not beneficially owned by
such Person (or by its Affiliates or Associates). Notwithstanding anything
contained in this Agreement to the contrary, the Rights shall not be exercisable
after the first occurrence of a Section 11(a)(ii) Event until such time as the
Company's right of redemption hereunder has expired. The Company may, at its
option, pay the Redemption Price in cash, shares of Common Stock (based on the
"current market price", as defined in Section 11(d)(i) hereof, of the Common
Stock at the time of redemption) or any other form of consideration deemed
appropriate by the Board of 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 for each Right so
held. Promptly 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 each holder's last address as it appears upon the
registry books of the Rights Agent or, prior to the Distribution Date, on the
registry books of the transfer agent for the Common Stock. Any notice which is
mailed in the manner herein provided shall be deemed given, whether or not the
holder receives the notice. Each such notice of redemption will state the method
by which the payment of the Redemption Price will be made.

    Section 24.  NOTICE OF CERTAIN EVENTS.

       (a) In case the Company shall propose, at any time after the Distribution
Date, (i) to pay any dividend payable in stock of any class to the holders of
Preferred Stock or to make any other distribution to the holders of Preferred
Stock (other than a regular quarterly cash dividend out of earnings or retained
earnings of the Company), or (ii) to offer to the holders of Preferred Stock
rights or warrants to subscribe for or to purchase any additional shares of
Preferred Stock or shares of stock of any class or any other securities, rights
or options, or (iii) to effect any reclassification of its Preferred Stock
(other than a reclassification involving only the subdivision of outstanding
shares of Preferred Stock), or (iv) to effect any consolidation or merger into
or with any other Person (other than a Subsidiary of the Company in a
transaction which complies with Section 11(o) hereof), or to effect any sale or
other transfer (or to permit one or more of its Subsidiaries to effect any sale
or other transfer), in one transaction or a series of related transactions, of
more than 50% of the assets or earning power of the Company and its Subsidiaries
(taken as a whole) to any other Person or Persons (other than the Company and/or
any of its Subsidiaries in one or more transactions each of which complies with
Section 11(o) hereof), or (v) to effect the liquidation, dissolution or winding
up of the Company, then, in each such case, the Company shall give to each
holder of a Rights Certificate, to the extent feasible and in accordance with
Section 25 hereof, a notice of such proposed action, which shall specify the
record date for the purposes of such stock dividend, distribution of rights or
warrants, or the date on which such reclassification, consolidation, merger,
sale, transfer, liquidation, dissolution, or winding up is to take place and the
date of participation therein by the holders of the shares of Preferred Stock,
if any such date is to be fixed, and such notice shall be so given in the case
of any action covered by clause (i) or (ii) above at least twenty (20) days
prior to the record date for determining holders of the shares of Preferred
Stock for purposes of such action, and in the case of any such other action, at
least twenty (20) days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of the shares of Preferred
Stock whichever shall be the earlier.

       (b) In case any of the events set forth in Section 11(a)(ii) hereof shall
occur, then, in any such case, (i) the Company shall as soon as practicable
thereafter give to each holder of a Rights Certificate, to the extent feasible
and in accordance with Section 25 hereof, a notice of the occurrence of such
event, which shall specify the event and the



                                      40
<PAGE>
 
consequences of the event to holders of Rights under Section 11(a)(ii)
hereof, and (ii) all references in the preceding paragraph to Preferred
Stock shall be deemed thereafter to refer to Common Stock and/or, if
appropriate, other securities.

Notices or demands authorized by this Agreement to be given or made by the
Company or the Rights Agent to the holder of any Rights Certificate (or,
if prior to the Distribution Date, to the holder of certificates
representing shares of Common Stock) shall be sufficiently given or made
if sent by first-class mail, postage prepaid, addressed to such holder at
the address of such holder as shown on the registry books of the Company.

    Section 26.  SUPPLEMENTS AND AMENDMENTS.  Prior to the
Distribution Date and subject to the penultimate sentence of this Section
26, the Company and the Rights Agent shall, if the Company so directs,
supplement or amend any provision of this Agreement without the approval
of any holders of certificates representing shares of Common Stock.  From
and after the Distribution Date and subject to the penultimate sentence of
this Section 26, the Company and the Rights Agent shall, if the Company so
directs, supplement or amend this Agreement without the approval of any



                                      41
<PAGE>
 
holders of Rights Certificates in order (i) to cure any ambiguity, (ii) to
correct or supplement any provision contained herein which may be
defective or inconsistent with any other provisions herein, (iii) to
shorten or lengthen any time period hereunder (which lengthening or
shortening, following the first occurrence of an event set forth in
clauses (i) and (ii) of the first 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 which the Company may
deem necessary or desirable and which shall not adversely affect the
interests of the holders of Rights Certificates (other than an Acquiring
Person or an Affiliate or Associate of an Acquiring Person); PROVIDED,
HOWEVER, 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.  Upon the delivery of a
certificate from an appropriate officer of the Company which states that
the proposed supplement or amendment is in compliance with the terms of
this Section 26, the Rights Agent shall execute such supplement or
amendment.  Notwithstanding anything contained in this Agreement to the
contrary, no supplement or amendment shall be made which changes the
Redemption Price, the Final Expiration Date, the Purchase Price or the
number of one one-thousandths of a share of Preferred Stock for which a
Right is exercisable.  Prior to the Distribution Date, the interests of
the holders of Rights shall be deemed coincident with the interests of the
holders of Common Stock.

    Section 27.  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 28.  DETERMINATIONS AND ACTIONS BY THE BOARD OF DIRECTORS,
ETC.  For all purposes of this Agreement, any calculation of the number of
shares of Common Stock outstanding at any particular time, including for
purposes of determining the particular percentage of such outstanding
shares of Common Stock of which any Person is the Beneficial Owner, shall
be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the
General Rules and Regulations under the Exchange Act.  The Board of
Directors of the Company (with, where specifically provided for herein,
the concurrence of the Continuing Directors) shall have the exclusive



                                      42
<PAGE>
 
power and authority to administer this Agreement and to exercise all
rights and powers specifically granted to the Board (with, where
specifically provided for herein, the concurrence of the Continuing
Directors) or to the Company, or as may be necessary or advisable in the
administration of this Agreement, including, without limitation, the right
and power to (i) interpret the provisions of this Agreement, and (ii) make
all determinations deemed necessary or advisable for the administration of
this Agreement (including a determination to redeem or not redeem the
Rights or to amend the Agreement).  All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y)
below, all omissions with respect to the foregoing) which are done or made
by the Board (with, where specifically provided for herein, the
concurrence of the Continuing Directors) in good faith, shall (x) be
final, conclusive and binding on the Company, the Rights Agent, the
holders of the Rights and all other parties, and (y) not subject the Board
or the Continuing Directors to any liability to the holders of the Rights.

    Section 29.  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, registered holders of the Common Stock)
any legal or equitable right, remedy or claim under this Agreement; but
this Agreement shall be for the sole and exclusive benefit of the Company,
the Rights Agent and the registered holders of the Rights Certificates
(and, prior to the Distribution Date, registered holders of the Common
Stock).

    Section 30.  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 twentieth day following the
date of such determination by the Board of Directors.  Without limiting



                                      43
<PAGE>
 
the foregoing, if any provision requiring a majority of the Board of
Directors of the Company to be Continuing Directors to act is held by any
court of competent jurisdiction or other authority to be invalid, void or
unenforceable, such determination shall then be made by the Board of
Directors of the Company in accordance with applicable law and the
Company's Amended and Restated Certificate of Incorporation and By-Laws.

       Section 31.  GOVERNING LAW.  This Agreement, 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 made and to be performed entirely within such
state.

    Section 32.  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 33.  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.

                         OPINION RESEARCH CORPORATION

    Pursuant to Section 151 of the General Corporation Law of the
State of Delaware, the undersigned officers of Opinion Research
Corporation, a corporation organized and existing under the General
Corporation Law of the State of Delaware (the "Corporation"), in
accordance with the provisions of Section 103 thereof, DO HEREBY CERTIFY:

    That pursuant to the authority conferred upon the Board of
Directors by the Certificate of Incorporation of the Corporation, the
Board of Directors on September 13, 1996 adopted the following resolution
creating a series of 10,000 shares of Preferred Stock designated as Series
A Junior Participating Preferred Stock:

    RESOLVED, that pursuant to the authority vested in the Board of
Directors of this Corporation in accordance with the provisions of its
Certificate of Incorporation, a series of Preferred Stock of the
Corporation be and it hereby is created, and that the designation and
amount thereof and the voting powers, preferences and relative,
participating, optional and other special rights of the shares of such
series, and the qualifications, limitations or restrictions thereof are as
follows:

    Section 1.  Designation and Amount.  The shares of such series
shall be designated as "Series A Junior Participating Preferred Stock" and
the number of shares constituting such series shall be 10,000.

    Section 2.  Dividends and Distributions.

       (A)  The holders of shares of Series A Junior Participating
Preferred Stock shall be entitled to receive, when, as and if declared by
the Board of Directors out of funds legally available for the purpose,
quarterly dividends payable in cash on the last day of March, June,



                                      A-1
<PAGE>
 
September and December in each year (each such date being referred to
herein as a "Quarterly Dividend Payment Date"), commencing on the first
Quarterly Dividend Payment Date after the first issuance of a share or
fraction of a share of Series A Junior Participating Preferred Stock, in
an amount per share (rounded to the nearest cent) equal to the greater of
(a) $0.01 or (b) 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, par value $0.01 per share, of the Corporation (the "Common Stock")
since the immediately preceding Quarterly Dividend Payment Date, or, with
respect to the first Quarterly Dividend Payment Date, since the first
issuance of any share or fraction of a share of Series A Junior
Participating Preferred Stock.  In the event the Corporation shall at any
time after September 13, 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 Junior Participating
Preferred Stock were entitled immediately prior to such event under clause
(b) of the preceding sentence shall be adjusted by multiplying such amount
by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of
which is the number of shares of Common Stock that were outstanding
immediately prior to such event.

       (B)  The Corporation shall declare a dividend or distribution
on the Series A Junior Participating Preferred Stock as provided in
Paragraph (A) above immediately after it declares a dividend or
distribution on the Common Stock (other than a dividend payable in shares
of Common Stock); provided that, in the event no dividend or distribution
shall have been declared on the Common Stock during the period between any
Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend
Payment Date, a dividend of $0.01 per share on the Series A Junior
Participating Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date.

       (C)  Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Junior Participating Preferred Stock from
the Quarterly Dividend Payment Date next preceding the date of issue of
such shares of Series A Junior 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



                                      A-2
<PAGE>
 
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 Junior
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 Junior 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 Junior Participating Preferred Stock
entitled to receive payment of a dividend or distribution declared
thereon, which record date shall be no more than thirty (30) days prior to
the date fixed for the payment thereof.

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

       (A)  Subject to the provision for adjustment hereinafter set
forth, each share of Series A Junior 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 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 Junior
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 Junior 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.



                                      A-3
<PAGE>
 
       (C)  (i)  If at any time dividends on any Series A Junior
Participating Preferred Stock shall be in arrears in an amount equal to
six (6) quarterly dividends thereon, the occurrence of such contingency
shall mark the beginning of a period  (herein called a "default period")
which shall extend until such time when all accrued and unpaid  dividends
for all previous quarterly dividend  periods and for the current quarterly
dividend period on all shares of Series A Junior  Participating Preferred
Stock then outstanding shall have been declared and paid or set apart for
payment.  During each default period, all holders of Preferred Stock
(including holders of the Series A Junior Participating Preferred Stock)
with dividends in arrears in an amount equal to six (6) quarterly
dividends thereon, voting as a class, irrespective of series, shall have
the right to elect two (2) Directors.

          (ii)  During any default period, such voting right of
the holders of Series A Junior Participating Preferred Stock may be
exercised initially at a special meeting called pursuant to subparagraph
(iii) of this Section 3(C) or at any annual meeting of stockholders, and
thereafter at annual meetings of stockholders, provided that such voting
right shall not be exercised unless the holders of ten percent (10%) in
number of shares of Preferred Stock outstanding shall be present in person
or by proxy.  The absence of a quorum of the holders of Common Stock shall
not affect the exercise by the holders of Preferred Stock of such voting
right.  At any meeting at which the holders of Preferred Stock shall
exercise such voting right initially during an existing default period,
they shall have the right, voting as a class, to elect Directors to fill
such vacancies, if any, in the Board of Directors as may then exist up to
two (2) Directors or, if such right is exercised at an annual meeting, to
elect two (2) Directors.  If the number which may be so elected at any
special meeting does not amount to the required number, the holders of the
Preferred Stock shall have the right to make such increase in the number
of Directors as shall be necessary to permit the election by them of the
required number.  After the holders of the Preferred Stock shall have
exercised their right to elect Directors in any default period and during
the continuance of such period, the number of Directors shall not be
increased or decreased except by vote of the holders of Preferred Stock as
herein provided or pursuant to the rights of any equity securities ranking
senior to or PARI PASSU with the Series A Junior Participating Preferred
Stock.

       (iii)  Unless the holders of Preferred Stock shall, during an



                                      A-4
<PAGE>
 
existing default period, have previously exercised their right to elect
Directors, the Board of Directors may order, or any stockholder or
stockholders owning in the aggregate not less than ten percent (10%) of
the total number of shares of Preferred Stock outstanding, irrespective of
series, may request, the calling of a special meeting of the holders of
Preferred Stock, which meeting shall thereupon be called by the President,
a Vice-President or the Secretary of the Corporation.  Notice of such
meeting and of any annual meeting at which holders of Preferred Stock are
entitled to vote pursuant to this Paragraph (C)(iii) shall be given to
each holder of record of Preferred Stock by mailing a copy of such notice
to such holder at such holder's last address as the same appears on the
books of the Corporation.  Such meeting shall be called for a time not
earlier than twenty (20) days and not later than sixty (60) days after
such order or request, or in default of the calling of such meeting within
sixty (60) days after such order or request, such meeting may be called on
similar notice by any stockholder or stockholders owning in the aggregate
not less than ten percent (10%) of the total number of shares of Preferred
Stock outstanding.  Notwithstanding the provisions of this Paragraph
(C)(iii), no such special meeting shall be called during the period within
sixty (60) days immediately preceding the date fixed for the next annual
meeting of the stockholders.

          (iv)  In any default period, the holders of Common
Stock, and other classes of stock of the Corporation if applicable, shall
continue to be entitled to elect the whole number of Directors until the
holders of Preferred Stock shall have exercised their right to elect two
(2) Directors voting as a class, after the exercise of which right (x) the
Directors so elected by the holders of Preferred Stock shall continue in
office until their successors shall have been elected by such holders or
until the expiration of the default period, and (y) any vacancy in the
Board of Directors may (except as provided in Paragraph (C)(ii) of this
Section 3) be filled by vote of a majority of the remaining Directors
theretofore elected by the holders of the class of stock which elected the
Director whose office shall have become vacant.  References in this
Paragraph (C) to Directors elected by the holders of a particular class of
stock shall include Directors elected by such Directors to fill vacancies
as provided in clause (y) of the foregoing sentence.

          (v)  Immediately upon the expiration of a default
period, (x) the right of the holders of Preferred Stock as a class to
elect Directors shall cease, (y) the term of any Directors elected by the
holders of Preferred Stock as a class shall terminate, and (z) the number
of Directors shall be such number as may be provided for in the



                                      A-5
<PAGE>
 
Certificate of Incorporation or By-laws of the Corporation irrespective of
any increase made pursuant to the provisions of Paragraph (C)(ii) of this
Section 3 (such number being subject, however, to change thereafter in any
manner provided by law or in the Certificate of Incorporation or By-laws
of the Corporation).  Any vacancies in the Board of Directors effected by
the provisions of clauses (y) and (z) in the preceding sentence may be
filled by a majority of the remaining Directors.

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

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

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

          (iii)  redeem or purchase or otherwise acquire for
consideration shares of any stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with the Series
A Junior 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



                                      A-6
<PAGE>
 
ranking junior (either as to dividends or upon dissolution, liquidation or
winding up) to the Series A Junior Participating Preferred Stock; or

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

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

    Section 5.  Reacquired Shares.  Any shares of Series A Junior
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
Junior Participating Preferred Stock unless, prior thereto, the holders of
shares of Series A Junior Participating Preferred Stock shall have
received an amount equal to $25,000 per share of Series A Junior
Participating Preferred Stock, 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



                                      A-7
<PAGE>
 
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 Junior 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 recapitalizations 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
Junior Participating Preferred Stock and Common Stock, respectively,
holders of Series A Junior 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 of the Series A Liquidation
Preference and the liquidation preferences of all other series of
Preferred Stock, if any, which rank on a parity (either as to dividends or
upon liquidation, dissolution or winding up) with the Series A Junior
Participating Preferred Stock, then such remaining assets shall be
distributed ratably to the holders of such parity shares in proportion to
their respective liquidation preferences.  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



                                      A-8
<PAGE>
 
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 Junior 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
Junior 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 Junior
Participating Preferred Stock shall not be redeemable.

    Section 9.  Amendment.  The Certificate of Incorporation of the
Corporation shall not be further amended in any manner which would
materially alter or change the powers, preferences or special rights of
the Series A Junior Participating Preferred Stock so as to affect them
adversely without the affirmative vote of the holders of a majority or
more of the outstanding shares of Series A Junior Participating Preferred
Stock, voting separately as a class.

    Section 10.  Fractional Shares.  Series A Junior Participating

Rights Certificate

OPINION RESEARCH CORPORATION

This certifies that [                         ], or registered assigns, is
the registered owner of the number of Rights set forth above, each of
which entitles the owner thereof, subject to the terms, provisions and
conditions of the Rights Agreement, dated as of September 13, 1996 (the
"Rights Agreement"), between Opinion Research Corporation, a Delaware
corporation (the "Company"), and StockTrans, Inc., a Pennsylvania
corporation (the "Rights Agent"), to purchase from the Company at any time
prior to 5:00 P.M. (New York City time) on October 3, 2006 at the office
or offices of the Rights Agent designated for such purpose, or its
successors as Rights Agent, one one- thousandth of a fully paid,
non-assessable share of Series A Junior Participating Preferred Stock (the
"Preferred Stock") of the Company, at a purchase price of $25.00 per one
one-thousandth of a share (the "Purchase Price"), upon presentation and
surrender of this Rights Certificate with the Form of Election to Purchase
and related Certificate duly executed.  The number of Rights evidenced by
this Rights Certificate (and the number of shares which may be purchased

<F1>  The portion of the legend in brackets shall be inserted only if
   applicable and shall replace the preceding sentence.



                                      B-1

upon exercise thereof) set forth above, and the Purchase Price per share
set forth above, are the number and Purchase Price as of September 13,
1996 based on the Preferred Stock as constituted at such date.  The
Company reserves the right to require prior to the occurrence of a
Triggering Event (as such term is defined in the Rights Agreement) that a
number of Rights be exercised so that only whole shares of Preferred Stock
will be issued.

    Upon the occurrence of a Section 11(a)(ii) Event (as such term is
defined in the Rights Agreement), if the Rights evidenced by this Rights
Certificate are beneficially owned by (i) an Acquiring Person or an
Affiliate or Associate of any Acquiring Person (as such terms are defined
in the Rights Agreement), (ii) a transferee of any Acquiring Person,
Associate or Affiliate, or (iii) under certain circumstances specified in
the Rights Agreement, a transferee of a person who, after such transfer,
became an Acquiring Person, or an Affiliate or Associate of an Acquiring
Person, such Rights shall become null and void and no holder hereof shall
have any right with respect to such Rights from and after the occurrence
of such Section 11(a)(ii) Event.

    As provided in the Rights Agreement, the Purchase Price and the
number and kind of shares of Preferred Stock or other securities which may
be purchased upon the exercise of the Rights evidenced by this Rights
Certificate are subject to modification and adjustment upon the happening
of certain events, including Triggering Events.

    This Rights Certificate is subject to all of the terms, provisions
and conditions of the Rights Agreement, which terms, provisions and
conditions are hereby incorporated herein by reference and made a part
hereof and to which Rights Agreement reference is hereby made for a full
description of the rights, limitations of rights, obligations, duties and
immunities hereunder of the Rights Agent, the Company and the holders of
the Rights Certificates, which limitations of rights include the temporary
suspension of the exercisability of such Rights under the specific
circumstances set forth in the Rights Agreement.  Copies of the Rights
Agreement are on file at the above-mentioned office of the Rights Agent
and are also available upon written request to the Rights Agent.

    This Rights Certificate, with or without other Rights
Certificates, upon surrender at the principal office or offices of the
Rights Agent designated for such purpose, may be exchanged for another
Rights Certificate or Rights Certificates of like tenor and date



                                      B-2
<PAGE>
 
evidencing Rights entitling the holder to purchase a like aggregate number
of one one-thousandths of a share of Preferred Stock as the Rights
evidenced by the Rights Certificate or Rights Certificates surrendered
shall have entitled such holder to purchase.  If this Rights Certificate
shall be exercised in part, the holder shall be entitled to receive upon
surrender hereof another Rights Certificate or Rights Certificates for the
number of whole Rights not exercised.

    Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate may be redeemed by the Company at its option
at a redemption price of $0.001 per Right at any time prior to the earlier
of the close of business on (i) the twentieth day following the Stock
Acquisition Date (as such time period may be extended pursuant to the
Rights Agreement), and (ii) the Final Expiration Date.  In addition, the
Rights may be exchanged, in whole or in part, for shares of the Common
Stock, or shares of preferred stock of the Company having essentially the
same value or economic rights as such shares. Immediately upon the action
of the Board of Directors of the Company authorizing any such exchange,
and without any further action or any notice, the Rights (other than
Rights which are not subject to such exchange) will terminate and the
Rights will only enable holders to receive the shares issuable upon such
exchange.  Under certain circumstances set forth in the Rights Agreement,
the decision to redeem the Rights shall require the concurrence of a
majority of the Continuing Directors (as such term is defined in the
Rights Agreement).

    No fractional shares of Preferred Stock will be issued upon the
exercise of any Right or Rights evidenced hereby (other than fractions
which are integral multiples of one one-thousandth of a share of Preferred
Stock, which may, at the election of the Company, be evidenced by
depositary receipts), but in lieu thereof a cash payment will be made, as
provided in the Rights Agreement.

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



                                      B-3

Rights evidenced by this Rights Certificate shall have been exercised as
provided in the Rights Agreement.

    This Rights Certificate shall not be valid or obligatory for any
purpose until it shall have been countersigned by the Rights Agent.

    WITNESS the facsimile signature of the proper officers of the
Company and its corporate seal.

                         SUMMARY OF RIGHTS TO PURCHASE
                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

    On September 13, 1996, the Board of Directors of Opinion Research
Corporation (the "Company") adopted a Shareholder Rights Plan, providing
that one right (a "Right") shall be attached to each share of common
stock, par value $0.01 per share, of the Company (the "Common Stock").
Each Right entitles the registered holder to purchase from the Company a
unit (a "Unit") consisting of one one-thousandth of a share of Series A
Junior Participating Preferred Stock, par value $0.01 per share (the
"Preferred Stock"), at a Purchase Price of $25.00 per Unit (the "Purchase
Price"), subject to adjustment.  The description and terms of the Rights
are set forth in the Rights Agreement (the "Rights Agreement"), dated as
of September 13, 1996, between the Company and StockTrans, Inc., a
Pennsylvania corporation, as Rights Agent (the "Rights Agent").

    Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate Rights
Certificate will be distributed.  The Rights will separate from the Common
Stock and a Distribution Date will occur upon the earlier of (i) ten (10)
days following a public announcement that a person or group of affiliated
or associated persons, other than an Exempted Person (as defined below),
(an "Acquiring Person") has acquired, or obtained the right to acquire,
beneficial ownership of 20% or more of the outstanding shares of Common
Stock (the "Stock Acquisition Date") or (ii) ten (10) business days
following the commencement of a tender offer or exchange offer that would
result in a person or group beneficially owning 20% or more of such
outstanding shares of Common Stock.  Until the Distribution Date, (i) the
Rights will be evidenced by the Common Stock certificates and will be
transferred with and only with such Common Stock certificates, (ii) new
Common Stock certificates will contain a notation incorporating the Rights
Agreement by reference and (iii) the surrender for transfer of any
certificates for Common Stock outstanding will also constitute the
transfer of the Rights associated with the Common Stock represented by
such certificate.

    Any person who, together with all affiliates and associates of
such person, is the beneficial owner of Common Stock, options and/or
warrants exercisable for shares of Common Stock representing 20% or more
of the shares of Common Stock outstanding on the date the Board of
Directors authorizes the rights dividend (the "Rights Dividend Declaration



                                      C-1
<PAGE>
 
Date"), will be an "Exempted Person."  In addition, any person who,
together with all affiliates and associates of such person, becomes the
beneficial owner of Common Stock, options and/or warrants exercisable for
shares of Common Stock representing 20% or more of the shares of Common
Stock then outstanding as a result of a purchase by the Company or any of
its Subsidiaries of shares of Common Stock will also be an "Exempted
Person."  However, any such person will no longer be deemed to be an
Exempted Person and will be deemed to be an Acquiring Person if such
person, together with all affiliates and associates of such person,
becomes the beneficial owner, at any time after the date such person
became the beneficial owner of 20% or more of the then outstanding shares
of Common Stock, of additional securities representing 1000 or more shares
of Common Stock, except if such additional securities are acquired (x)
pursuant to the exercise of options or warrants to purchase Common Stock
outstanding and beneficially owned by such person as of the date such
person became the beneficial owner of 20% or more of the then outstanding
shares of Common Stock or as a result of an adjustment to the number of
shares of Common Stock for which such options or warrants are exercisable
pursuant to the terms thereof, or (y) as a result of a stock split, stock
dividend or the like.  A purchaser, assignee or transferee of the shares
of Common Stock (or options or warrants exercisable for Common Stock) of
an Exempted Person will not thereby become an Exempted Person.

    The Rights are not exercisable until the Distribution Date and
will expire at the close of business on October 3, 2006 unless earlier
redeemed by the Company as described below.

    As soon as practicable after the Distribution Date, Rights
Certificates will be mailed to holders of record of the Common Stock as of
the close of business on the Distribution Date and, thereafter, the
separate Rights Certificates alone will represent the Rights. Except as
otherwise determined by the Board of Directors, only shares of Common
Stock prior to the Distribution Date will be issued with Rights.

    In the event that an Acquiring Person, other than an Exempted
Person, becomes the beneficial owner of 20% or more of the then
outstanding shares of Common Stock (unless such acquisition is made
pursuant to a tender or exchange offer for all outstanding shares of the
Company, at a price determined by a majority of the independent directors
of the Company who are not representatives, nominees, Affiliates or
Associates of an Acquiring Person to be fair and otherwise in the best
interest of the Company and its stockholders), each holder of a Right will



                                      C-2
<PAGE>
 
thereafter have the right to receive, upon exercise, Common Stock (or, in
certain circumstances, cash, property or other securities of the Company),
having a value equal to four times the Exercise Price of the Right.  The
Exercise Price is the Purchase Price times the number of shares of Common
Stock associated with each Right (initially, one). Notwithstanding any of
the foregoing, following the occurrence of any of the events set forth in
this paragraph (the "Flip-In Events"), all Rights that are, or (under
certain circumstances specified in the Rights Agreement) were,
beneficially owned by any Acquiring Person will be null and void.
However, Rights are not exercisable following the occurrence of any of the
Flip-In Events set forth above until such time as the Rights are no longer
redeemable by the Company as set forth below.

    In the event that following the Stock Acquisition Date, (i) the
Company engages in a merger or business combination transaction in which
the Company is not the surviving corporation (other than a merger that
follows a tender offer determined to be fair to the stockholders of the
Company, as described in the preceding paragraph); (ii) the Company
engages in a merger or business combination transaction in which the
Company is the surviving corporation and the Common Stock is changed or
exchanged; or (iii) 50% or more of the Company's assets or earning power
is sold or transferred, each holder of a Right (except Rights which have
previously been voided as set forth above) shall thereafter have the right
to receive, upon exercise of the Right, common stock of the acquiring
company having a value equal to four times the Exercise Price of the
Right.


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

    With certain exceptions, no adjustments in the Purchase Price will
be required until cumulative adjustments amount to at least 1% of the
Purchase Price. No fractional Units will be issued and, in lieu thereof,
an adjustment in cash will be made based on the market price of the



                                      C-3
<PAGE>
 
Preferred Stock on the last trading date prior to the date of exercise.

    At any time until twenty (20) days following the Stock Acquisition
Date, the Company may redeem the Rights in whole, but not in part, at a
price of $0.001 per Right.  Under certain circumstances, the decision to
redeem shall require the concurrence of a majority of the Continuing
Directors (as defined below). Immediately upon the action of the Board of
Directors ordering redemption of the Rights, the Rights will terminate and
the only right of the holders of Rights will be to receive the $0.001
redemption price.

    The term "Continuing Director" means any member of the Board of
Directors of the Company who was a member of the Board prior to the
adoption of the Rights Plan and any person who is subsequently elected to
the Board if such person is recommended or approved by a majority of the
Continuing Directors, but shall not include an Acquiring Person, or an
affiliate or associate of an Acquiring Person, or any representative of
the foregoing entities.

    Until a Right is exercised, the holder thereof, as such, will have
no rights as a stockholder of the Company, including, without limitation,
the right to vote or to receive dividends.  While the distribution of the
Rights will not be taxable to stockholders or to the Company, stockholders
may, depending upon the circumstances, recognize taxable income in the
event that the Rights become exercisable for Common Stock (or other
consideration) of the Company as set forth above.

    Other than those provisions relating to the principal economic
terms of the Rights, any of the provisions of the Rights Agreement may be
amended by the Board of Directors of the Company prior to the Distribution
Date.  After the Distribution Date, the provisions of the Rights Agreement
may be amended by the Board (in certain circumstances, with the
concurrence of the Continuing Directors) in order to cure any ambiguity,
to make changes which do not adversely affect the interests of holders of
Rights (excluding the interest 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 at such time as the Rights are not redeemable.

    A copy of the Rights Agreement is being filed with the Securities
and Exchange Commission as an Exhibit to a Registration Statement on Form
8-A.  A copy of the Rights Agreement is available free of charge from the



                                      C-4

qualified in its entirety by reference to the Rights Agreement, which is
