Item 1.           DESCRIPTION OF SECURITIES TO BE REGISTERED

                  On February 13, 1998, pursuant to a Preferred Shares Rights
Agreement (the "Rights Agreement") between Cymer, Inc. (the "Company") and
ChaseMellon Shareholder Services, L.L.C., as Rights Agent (the "Rights Agent"),
the Company's Board of Directors declared a dividend of one right (a "Right") to
purchase one one-thousandth share of the Company's Series A Participating
Preferred Stock (the "Series A Preferred") for each outstanding share of Common
Stock, $.001 par value (the "Common Shares"), of the Company. The dividend is
payable on March 2, 1998 (the "Record Date") to stockholders of record as of the
close of business on that date. Each Right entitles the registered holder to
purchase from the Company one one-thousandth of a share of Series A Preferred at
an exercise price of $100.00 (the "Exercise Price"), subject to adjustment.

         The following summary of the principal terms of the Rights Agreement is
a general description only and is subject to the detailed terms and conditions
of the Rights Agreement. A copy of the Rights Agreement is attached as Exhibit 1
to this Registration Statement and is incorporated herein by reference.

Rights Evidenced by Common Share Certificates

         The Rights will not be exercisable until the Distribution Date (defined
below). Certificates for the Rights ("Rights Certificates") will not be sent to
stockholders and the Rights will attach to and trade only together with the
Common Shares. Accordingly, Common Share certificates outstanding on the Record
Date will evidence the Rights related thereto, and Common Share certificates
issued after the Record Date will contain a notation incorporating the Rights
Agreement by reference. Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender or transfer of any certificates for
Common Shares, outstanding as of the Record Date, even without notation or a
copy of the summary of rights (attached as Exhibit C to the Rights Agreement)
being attached thereto, will also constitute the transfer of the Rights
associated with the Common Shares represented by such certificate.

Distribution Date

         The Rights will separate from the Common Shares, Rights Certificates
will be issued and the Rights will become exercisable upon the earlier of: (i)
the close of business on the tenth day (or such later date as may be determined
by a majority of the Board of Directors, excluding directors affiliated with the
Acquiring Person, as defined below (the "Continuing Directors")) following a
public announcement that a person or group of affiliated or associated persons
(an "Acquiring Person") has acquired, or obtained the right to acquire,
beneficial ownership of 15% or more of the outstanding Common Shares, or (ii)
the close of business on the tenth business day (or such later date as may be
determined by a majority of the Continuing Directors) following the commencement
of, or announcement of an intention to make, a tender offer or exchange offer
the consummation of which would result in the beneficial ownership by a person
or group of 15% or more of the outstanding Common Shares. The earlier of such
dates is referred to as the "Distribution Date."



                                       -2-

<PAGE>   3



Issuance of Rights Certificates; Expiration of Rights

         As soon as practicable following the Distribution Date, separate Rights
Certificates will be mailed to holders of record of the Common Shares as of the
close of business on the Distribution Date and such separate Rights Certificates
alone will evidence the Rights from and after the Distribution Date. All Common
Shares issued prior to the Distribution Date will be issued with Rights. Common
Shares issued after the Distribution Date may be issued with Rights if such
shares are issued (i) upon the conversion of outstanding convertible debentures
or any other convertible securities issued after adoption of the Rights
Agreement or (ii) pursuant to the exercise of stock options or under employee
benefit plans or arrangements unless such issuance would result in (or create a
risk that) such options, plans or arrangements would not qualify for otherwise
available special tax treatment. Except as otherwise determined by the Board of
Directors, no other Common Shares issued after the Distribution Date will be
issued with Rights. The Rights will expire on the earliest of (i) the close of
business on February 13, 2008 (the "Final Expiration Date"), (ii) redemption or
exchange of the Rights as described below, or (iii) consummation of an
acquisition of the Company satisfying certain conditions by a person who
acquired shares pursuant to a Permitted Offer as described below.

Initial Exercise of the Rights

         Following the Distribution Date, and until one of the further events
described below, holders of the Rights will be entitled to receive, upon
exercise and the payment of $100.00 per Right, one one-thousandth share of the
Series A Preferred. In the event that the Company does not have sufficient
Series A Preferred available for all Rights to be exercised, or the Board of
Directors decides that such action is necessary and not contrary to the
interests of Rights holders, the Company may instead substitute cash, assets or
other securities for the Series A Preferred for which the Rights would have been
exercisable under this provision or as described below.

Right to Buy Company Common Shares

         Unless the Rights are earlier redeemed, in the event that an Acquiring
Person becomes the beneficial owner of 15% or more of the Company's Common
Shares then outstanding (other than pursuant to a Permitted Offer), then proper
provision will be made so that each holder of a Right which has not theretofore
been exercised (other than Rights beneficially owned by the Acquiring Person,
which will thereafter be void) will thereafter have the right to receive, upon
exercise, Common Shares having a value equal to two times the Exercise Price.
Rights are not exercisable following the occurrence of an event as described
above until such time as the Rights are no longer redeemable by the Company as
set forth below.

Right to Buy Acquiring Company Stock

         Similarly, unless the Rights are earlier redeemed, in the event that,
after the Shares Acquisition Date (as defined below), (i) the Company is
acquired in a merger or other business combination transaction, or (ii) 50% or
more of the Company's consolidated assets or earning power are sold (other than
in transactions in the ordinary course of business), proper provision must be
made so that each

                                       -3-

<PAGE>   4



holder of a Right which has not theretofore been exercised (other than Rights
beneficially owned by the Acquiring Person, which will thereafter be void) will
thereafter have the right to receive, upon exercise, shares of common stock of
the acquiring company having a value equal to two times the Exercise Price
(unless the transaction satisfies certain conditions and is consummated with a
person who acquired shares pursuant to a Permitted Offer, in which case the
Rights will expire).

Permitted Offer

         A Permitted Offer means a tender offer for all outstanding Common
Shares that has been determined by a majority of the Continuing Directors to be
adequate and otherwise in the best interests of the Company and its
stockholders. Where the Board of Directors has determined that a tender offer
constitutes a Permitted Offer, the Rights will not become exercisable to
purchase Common Shares or shares of the acquiring company (as the case may be)
at the discounted price described above.

Exchange Provision

         At any time after the acquisition by an Acquiring Person of 15% or more
of the Company's outstanding Common Shares and prior to the acquisition by such
Acquiring Person of 50% or more of the Company's outstanding Common Shares, the
Board of Directors of the Company may exchange the Rights (other than Rights
owned by the Acquiring Person), in whole or in part, at an exchange ratio of one
Common Share per Right (subject to adjustment).

Redemption

         Rights will be redeemable at the Company's option for $0.01 per Right
at any time on or prior to public announcement that a Person has acquired
beneficial ownership of 15% or more of the Company's Common Stock (the "Shares
Acquisition Date").

Adjustments to Prevent Dilution

         The Purchase Price payable, the number of Rights, and the number of
Series A Preferred or Common Shares or other securities or property issuable
upon exercise of the Rights are subject to adjustment from time to time in
connection with the dilutive issuances by the Company as set forth in the Rights
Agreement. With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price.

Cash Paid Instead of Issuing Fractional Shares

         No fractional portion less than integral multiples of one Common Share
will be issued upon exercise of a Right and in lieu thereof, an adjustment in
cash will be made based on the market price of the Common Shares on the last
trading date prior to the date of exercise.


                                       -4-

<PAGE>   5



No Stockholders' Rights Prior to Exercise

         Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company (other than any rights resulting from
such holder's ownership of Common Shares), including, without limitation, the
right to vote or to receive dividends.

Amendment of Rights Agreement

         The provisions of the Rights Agreement may be supplemented or amended
by the Board of Directors in any manner prior to the close of business on the
Distribution Date without the approval of Rights holders. After the Distribution
Date, the provisions of the Rights Agreement may be amended by the Board of
Directors in order to cure any ambiguity, defect or inconsistency, to make
changes which do not adversely affect the interests of holders of Rights
(excluding the interests of any Acquiring Person), or to shorten or lengthen any
time period under the Rights Agreement; provided, however, that no amendment to
adjust (i) the time period governing redemption shall be made at such time as
the Rights are not redeemable, or (ii) any other time period unless such
lengthening is for the purpose of protecting, enhancing or clarifying the rights
of and/or benefits to the holders of the Rights.

Rights and Preferences of the Series A Preferred

         Series A Preferred purchasable upon exercise of the Rights will not be
redeemable. Each share of Series A Preferred will be entitled to an aggregate
dividend of 1,000 times the dividend declared per Common Share. In the event of
liquidation, the holders of the Series A Preferred will be entitled to a minimum
preferential liquidation payment equal to 1,000 times the per share amount to be
distributed to the holders of the Common Shares. Each share of Series A
Preferred will have 1,000 votes, voting together with the Common Shares. In the
event of any merger, consolidation or other transaction in which the Common
Shares are changed or exchanged, each share of Series A Preferred will be
entitled to receive 1,000 times the amount received per Common Share. These
rights are protected by customary anti-dilution provisions.

         Because of the nature of the dividend, liquidation and voting rights of
the shares of Series A Preferred, the value of the one one-thousandth interest
in a share of Series A Preferred purchasable upon exercise of each Right should
approximate the value of one Common Share.

Certain Anti-takeover Effects

         The Rights approved by the Board of Directors are designed to protect
and maximize the value of the outstanding equity interests in the Company in the
event of an unsolicited attempt by an acquiror to take over the Company, in a
manner or on terms not approved by the Board of Directors. Takeover attempts
frequently include coercive tactics to deprive the Company's Board of Directors
and its stockholders of any real opportunity to determine the destiny of the
Company. The Rights have been declared by the Board of Directors in order to
deter such tactics, including a gradual accumulation of shares in the open
market of a 15% or greater position to be followed by a merger or a partial or
two-tier tender offer that does not treat all stockholders equally. These
tactics unfairly pressure stockholders,

                                       -5-

<PAGE>   6



squeeze them out of their investment without giving them any real choice and
deprive them of the full value of their shares.

         The Rights are not intended to prevent a takeover of the Company and
will not do so. The Rights may be redeemed by the Company at $.01 per Right at
any time on or prior to the public announcement of the accumulation of 15% or
more of the Company's shares by a single acquiror or group. Accordingly, the
Rights should not interfere with any merger or business combination approved by
the Board of Directors.

         Issuance of the Rights does not in any way weaken the financial
strength of the Company or interfere with its business plans. The issuance of
the Rights themselves has no dilutive effect, will not affect reported earnings
per share, should not be taxable to the Company or to its stockholders, and will
not change the way in which the Company's shares are presently traded. The
Company's Board of Directors believes that the Rights represent a sound and
reasonable means of addressing the complex issues of corporate policy created by
the current takeover environment.

         However, the Rights may have the effect of rendering more difficult or
discouraging an acquisition of the Company deemed undesirable by the Board of
Directors. The Rights may cause substantial dilution to a person or group that
attempts to acquire the Company on terms or in a manner not approved by the
Company's Board of Directors, except pursuant to an offer conditioned upon the
negation, purchase or redemption of the Rights.

                                RIGHTS AGREEMENT


         Agreement, dated as of February 13, 1998, between Cymer, Inc. (the
"Company"), a Nevada corporation, and ChaseMellon Shareholder Services, L.L.C.

         On February 13, 1998 (the "RIGHTS DIVIDEND DECLARATION DATE"), the
Board of Directors of the Company authorized and declared a dividend of one
Preferred Share Purchase Right (a "RIGHT") for each Common Share (as hereinafter
defined) of the Company outstanding as of the Close of Business (as hereinafter
defined) on March 2, 1998 (the "RECORD DATE"), each Right representing the right
to purchase one one-thousandth of a share of Series A Participating Preferred
Stock (as such number may be adjusted pursuant to the provisions of this
Agreement), having the rights, preferences and privileges set forth in the form
of Certificate of Designations of Rights, Preferences and Privileges of Series A
Participating Preferred Stock attached hereto as Exhibit A, upon the terms and
subject to the conditions herein set forth, and further authorized and directed
the issuance of one Right (as such number may be adjusted pursuant to the
provisions of this Agreement) with respect to each Common Share that shall
become outstanding between the Record Date and the earlier of the Distribution
Date and the Expiration Date (as such terms are hereinafter defined), and in
certain circumstances after the Distribution Date.

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

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

                  (a) "ACQUIRING PERSON" shall mean any Person who or which,
together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the Common Shares then outstanding, but shall
not include the Company, any Subsidiary of the Company or any employee benefit
plan of the Company or of any Subsidiary of the Company, or any Person
organized, appointed or established by the Company for or pursuant to the terms
of any such plan. Notwithstanding the foregoing, no Person shall be deemed to be
an Acquiring Person as the result of an acquisition of Common Shares by the
Company which, by reducing the number of shares outstanding, increases the
proportionate number of shares beneficially owned by such Person to 15% or more
of the Common Shares of the Company then outstanding; provided, however, that if

intention of changing or influencing control of the Company, and if such Person
divested or divests as promptly as practicable a sufficient number of Common
Shares so that such Person would no longer be an "Acquiring Person," as defined
pursuant to the foregoing provisions of this paragraph (a), then such Person
shall not be deemed to be or to have become an "Acquiring Person" for any

foregoing provisions of this paragraph (a), unless and until such time as such
Person shall become the Beneficial Owner of additional Common Shares (other than
pursuant to a dividend or distribution paid or made by the Company on the

securities tendered pursuant to a tender or exchange offer made by or on behalf
of such Person or any of such Person's Affiliates or Associates until such

daily closing prices per share of such Security for the thirty (30) consecutive
Trading Days immediately prior to but not including such date, and for purposes

of the daily closing prices per share of such Security for the ten (10)
consecutive Trading Days immediately prior to but not including such date;
provided, however, that in the event that the Current Per Share Market Price of
the Security is determined during a period following the announcement by the

be used. If the Preferred Shares are not publicly traded, the Current Per Share
Market Price of the Preferred Shares shall be conclusively deemed to be the
Current Per Share Market Price of the Common Shares as determined pursuant to
this Section 1(k), as appropriately adjusted to reflect any stock split, stock
dividend or similar transaction occurring after the date hereof, multiplied by
1000. If the Security is not publicly held or so listed or traded, Current Per
Share Market Price shall mean the fair value per share as determined in good
faith by the Board of Directors of the Company, whose determination shall be

certificates for Common Shares registered in the names of the holders thereof

Certificates and may be transferred by the transfer of the Rights Certificates
as permitted hereby, separately and apart from any transfer of Common Shares,
and the holders of such Rights

                                       -7-

<PAGE>   11



Certificates as listed in the records of the Company or any transfer agent or

of the Company's transfer agent and registrar. With respect to certificates for
Common Shares outstanding as of the Record Date, until the Distribution Date,

holders thereof. Until the Distribution Date (or, if earlier, the Expiration
Date), the surrender for transfer of any certificate for Common Shares
outstanding on the Record Date, with or without a copy of the Summary of Rights,

Shares represented thereby.

Distribution Date. Certificates representing such Common Shares shall also be
deemed to be certificates for Rights, and shall bear the following legend:

         THE TERMS OF WHICH ARE HEREBY INCORPORATED HEREIN BY REFERENCE AND A
         COPY OF WHICH IS ON FILE AT THE PRINCIPAL EXECUTIVE OFFICES OF THE
         COMPANY. UNDER CERTAIN CIRCUMSTANCES, AS SET FORTH IN THE RIGHTS
         AGREEMENT, SUCH RIGHTS WILL BE EVIDENCED BY SEPARATE CERTIFICATES AND

         TO, OR HELD BY, ANY PERSON WHO IS, WAS OR BECOMES AN ACQUIRING PERSON

         RIGHTS AGREEMENT), WHETHER CURRENTLY HELD BY OR ON BEHALF OF SUCH
         PERSON OR BY ANY SUBSEQUENT HOLDER, MAY BECOME NULL AND VOID.

With respect to such certificates containing the foregoing legend, until the
earlier of (i) the Distribution Date or (ii) the Expiration Date, the Rights
associated with the Common Shares represented by such certificates shall be
evidenced by such certificates alone, and the surrender for transfer of any such
certificate shall also constitute the transfer of the Rights associated with the
Common Shares represented thereby.

                  (d) In the event that the Company purchases or acquires any
Common Shares after the Record Date but prior to the Distribution Date, any
Rights associated with such Common Shares shall be deemed canceled and retired
so that the Company shall not be entitled to exercise any Rights associated with
the Common Shares which are no longer outstanding.

         Section 4. Form of Rights Certificates.

                  (a) The Rights Certificates (and the forms of election to

thereof) shall be substantially in the form of 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 which do
not affect the duties or responsibilities of the Rights Agent and as are not
inconsistent with the provisions of this Agreement, or as may be required to
comply with any applicable law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange or automated
quotation system, on which the Rights may from time to time be listed or
included, or to conform to usage. Subject to the provisions of Section 11 and
Section 22 hereof, the Rights Certificates, whenever distributed, shall be dated
as of the Record Date (or in the case of Rights represented by Common Shares
issued by the Company after the Record Date, as of the date of issuance of such
Common Shares) and on their face shall entitle the holders thereof to purchase
such number of one one-thousandths of a Preferred Share as shall be set forth
therein at the price set forth therein (such exercise price per one
one-thousandth of a Preferred Share being hereinafter referred to as the
"EXERCISE PRICE" and the aggregate Exercise Price of all Preferred Shares
issuable upon exercise of one Right being hereinafter referred to as the "TOTAL
EXERCISE PRICE"), but the number and type of securities purchasable upon the
exercise of each Right and the Exercise Price shall be subject to adjustment as
provided herein.

                  (b) Any Rights Certificate issued pursuant to Section 3(a) or
Section 22 hereof that represents Rights beneficially owned by: (i) an Acquiring
Person or any Associate or Affiliate of an Acquiring Person, (ii) a transferee
of an Acquiring Person (or of any such Associate or Affiliate) who becomes a
transferee after the Acquiring Person becomes such or (iii) a transferee of an
Acquiring Person (or of any such Associate or Affiliate) who becomes a
transferee prior to or concurrently with the Acquiring Person becoming such and
receives such Rights pursuant to either (A) a transfer (whether or not for
consideration) from the Acquiring Person to holders of equity interests in such
Acquiring Person or to any Person with whom such Acquiring Person has any
continuing agreement, arrangement or understanding regarding the transferred
Rights or (B) a transfer which a majority of the Continuing Directors then in
office has determined is part of an agreement, arrangement or understanding
which has as a primary purpose or effect avoidance of Section 7(e) hereof, and,
provided that the Company shall have notified the Rights Agent that this Section
4(b) applies, 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

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

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

         Section 6. Transfer, Split Up, Combination and Exchange of Rights
                    Certificates; Mutilated, Destroyed, Lost or Stolen Rights 
                    Certificates.

                  (a) Subject to the provisions of Sections 7(e), 14 and 24
hereof, at any time after the Close of Business on the Distribution Date, and at
or prior to the Close of Business on the Expiration Date, any Rights Certificate
or Rights Certificates may be transferred, split up, combined or exchanged for
another Rights Certificate or Rights Certificates, entitling the registered
holder to purchase a like number of one one-thousandths of a Preferred Share
(or, following a Triggering Event, other securities, cash or other assets, as
the case may be) as the Rights Certificate or Rights Certificates surrendered
then entitled such holder to purchase. Any registered holder desiring to
transfer, split up, combine or exchange any Rights Certificate or Rights
Certificates shall make such request in writing delivered to the Rights Agent,
and shall surrender the Rights Certificate or Rights Certificates to be
transferred, split up, combined or exchanged at the office of the Rights Agent
designated for such purpose. Neither the Rights Agent nor the Company shall be
obligated to take any action whatsoever with respect to the transfer of any such
surrendered Rights Certificate until the registered holder shall have completed
and signed the certificate contained in the form of assignment on the reverse
side of such Rights Certificate


                                      -10-

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 or the Rights Agent shall reasonably request. Thereupon
the Rights Agent shall, subject to Sections 7(e), 14 and 24 hereof, countersign
and deliver to the person entitled thereto a Rights Certificate or Rights
Certificates, as the case may be, as so requested. The Company may require
payment of a sum sufficient to cover any tax or governmental charge that may be
imposed in connection with any transfer, split up, combination or exchange of
Rights Certificates. The Rights Agent shall have no duty or obligation under
this Section unless and until it is satisfied that all such taxes and/or charges
have been paid.

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

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

                  (a) Subject to Sections 7(e), 23(b) and 24(b) hereof, the
registered holder of any Rights Certificate may exercise the Rights evidenced
thereby (except as otherwise provided herein) in whole or in part at any time
after the Distribution Date and prior to the Close of Business on the Expiration
Date by surrender of the Rights Certificate, with the form of election to
purchase on the reverse side thereof duly executed, to the Rights Agent at the
office of the Rights Agent designated for such purpose, together with payment of
the Exercise Price for each one one-thousandth of a Preferred Share (or,
following a Triggering Event, other securities, cash or other assets as the case
may be) as to which the Rights are exercised.

                  (b) The Exercise Price for each one one-thousandth of a
Preferred Share issuable pursuant to the exercise of a Right shall initially be
One-Hundred Dollars ($100.00), shall be subject to adjustment from time to time
as provided in Sections 11 and 13 hereof and shall be payable in lawful money of
the United States of America in accordance with paragraph (c) below.

                  (c) Upon receipt of a Rights Certificate representing
exercisable Rights, with the form of election to purchase duly executed,
accompanied by payment of the Exercise Price for the number of one
one-thousandths of a Preferred Share (or, following a Triggering Event, other
securities, cash or other assets as the case may be) to be purchased and an
amount equal to any applicable tax or governmental charge required to be paid by
the holder of such Rights Certificate in accordance with Section 9(e) hereof,
the Rights Agent shall, subject to Section 20(k) hereof, thereupon promptly (i)
(A) requisition from any transfer agent of the Preferred Shares (or make
available, if the Rights Agent is the transfer agent for the Preferred Shares) a
certificate or certificates for the number of one-thousandths of a Preferred
Share (or, following a Triggering Event, other securities, cash or other assets
as the case may be) 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

                                      -11-

<PAGE>   15



of one-thousandths of a Preferred Share (or, following a Triggering Event, other
securities, cash or other assets as the case may be) issuable upon exercise of
the Rights hereunder with a depositary agent, requisition from the depositary
agent depositary receipts representing such number of one-thousandths of a
Preferred Share (or, following a Triggering Event, other securities, cash or
other assets as the case may be) as are to be purchased (in which case
certificates for the Preferred Shares (or, following a Triggering Event, other
securities, cash or other assets as the case may be) represented by such
receipts shall be deposited by the transfer agent with the depositary agent) and
the Company hereby directs the depositary agent to comply with such request,
(ii) when appropriate, requisition from the Company the amount of cash to be
paid in lieu of issuance of fractional shares in accordance with Section 14
hereof, (iii) after receipt of such certificates or depositary receipts, cause
the same to be delivered to or upon the order of the registered holder of such
Rights Certificate, registered in such name or names as may be designated by
such holder and (iv) when appropriate, after receipt thereof, deliver such cash
to or upon the order of the registered holder of such Rights Certificate. The
payment of the Exercise Price (as such amount may be reduced (including to zero)
pursuant to Section 11(a)(iii) hereof) and an amount equal to any applicable tax
or governmental change required to be paid by the holder of such Rights
Certificate in accordance with Section 9(e) hereof, may be made in cash or by
certified bank check, cashier's check or bank draft payable to the order of the
Company. In the event that the Company is obligated to issue securities of the
Company other than Preferred Shares, 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 necessary to comply
with this Agreement.

                  (d) In case the registered holder of any Rights Certificate
shall exercise less than all the Rights evidenced thereby, a new Rights
Certificate evidencing Rights equivalent to the Rights remaining unexercised
shall be issued by the Rights Agent to the registered holder of such Rights
Certificate or to his or her duly authorized assigns, subject to the provisions
of Sections 6 and 14 hereof.

                  (e) Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Triggering Event, any Rights
beneficially owned by (i) an Acquiring Person or an Associate or Affiliate of an
Acquiring Person, (ii) a transferee of an Acquiring Person (or of any such
Associate or Affiliate) who becomes a transferee after the Acquiring Person
becomes such (a "POST-EVENT TRANSFEREE"), (iii) a transferee of an Acquiring
Person (or of any such Associate or Affiliate) who becomes a transferee prior to
or concurrently with the Acquiring Person becoming such and receives such Rights
pursuant to either (A) a transfer (whether or not for consideration) from the
Acquiring Person to holders of equity interests in such Acquiring Person or to
any Person with whom the Acquiring Person has any continuing agreement,
arrangement or understanding regarding the transferred Rights or (B) a transfer
which a majority of the Continuing Directors then in office has determined is
part of a plan, arrangement or understanding which has as a primary purpose or
effect the avoidance of this Section 7(e) (a "PRE-EVENT TRANSFEREE") or (iv) any
subsequent transferee receiving transferred Rights from a Post-Event Transferee
or a Pre-Event Transferee, either directly or through one or more intermediate
transferees, shall become null and void without any further action and no holder
of such Rights shall have any rights whatsoever with respect to such Rights,
whether under any provision of this Agreement or otherwise. The Company shall
notify the Rights Agent when this Section 7(e) applies and shall use all
reasonable efforts to ensure that the provisions of this Section 7(e) and
Section 4(b) hereof

                                      -12-

<PAGE>   16



are complied with, but neither the Company nor the Rights Agent shall have any
liability to any holder of Rights Certificates or to any other Person as a
result of the Company's failure to make any determinations with respect to an
Acquiring Person or any of such Acquiring Person's Affiliates, Associates or
transferees hereunder.

                  (f) Notwithstanding anything in this Agreement to the
contrary, neither the Rights Agent nor the Company shall be obligated to
undertake any action with respect to a registered holder upon the occurrence of
any purported exercise as set forth in this Section 7 unless such registered
holder shall, in addition to having complied with the requirements of Section
7(a), have (i) properly 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 or the Rights Agent shall
reasonably request.

         Section 8. Cancellation and Destruction of Rights Certificates. All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in canceled form,
or, if surrendered to the Rights Agent, shall be canceled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement, and the Rights Agent shall so cancel and
retire, any 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 Preferred Shares.

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

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


                                      -13-

<PAGE>   17



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

                  (d) The Company covenants and agrees that it will take all
such action as may be necessary to ensure that all Preferred Shares (or other
securities of the Company) delivered upon exercise of Rights shall, at the time
of delivery of the certificates for such securities (subject to payment of the
Exercise Price), be duly and validly authorized and issued and fully paid and
nonassessable shares.

                  (e) The Company further covenants and agrees that it will pay
when due and payable any and all taxes and governmental charges which may be
payable in respect of the original issuance or delivery of the Rights
Certificates or of any Preferred Shares (or other securities of the Company)
upon the exercise of Rights. The Company shall not, however, be required to pay
any transfer tax or charge which may be payable in respect of any transfer or
delivery of Rights Certificates to a person other than, or the issuance or
delivery of certificates or depositary receipts for the Preferred Shares (or
other securities of the Company) in a name other than that of, the registered
holder of the Rights Certificate evidencing Rights surrendered for exercise or
to issue or to deliver any certificates or depositary receipts for Preferred
Shares (or other securities of the Company) upon the exercise of any Rights
until any such tax or charge shall have been paid (any such tax or charge 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 or
charge is due.

         Section 10. Record Date. Each Person in whose name any certificate for
a number of one-thousandths of a Preferred Share (or other securities) is issued
upon the exercise of Rights shall for all purposes be deemed to have become the
holder of record of the Preferred Shares (or other securities) represented
thereby on, and such certificate shall be dated, the date upon which the Rights
Certificate evidencing such Rights was duly surrendered and payment of the
Exercise Price with respect to which

                                      -14-

<PAGE>   18



the Rights have been exercised (and any applicable taxes and charges) was made;
provided, however, that if the date of such surrender and payment is a date upon
which the transfer books of the Company are closed, such Person shall be deemed
to have become the record holder of such shares on, and such certificate shall
be dated, the next succeeding Business Day on which the transfer books of the
Company are open. Prior to the exercise of the Rights evidenced thereby, the
holder of a Rights Certificate shall not be entitled to any rights of a holder
of Preferred Shares (or other securities) for which the Rights shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights, and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

         Section 11. Adjustment of Exercise Price, Number of Shares or Number of
Rights. The Exercise Price, the number and kind of shares or other property
covered by each Right and the number of Rights outstanding are subject to
adjustment from time to time as provided in this Section 11.

                  (a)       (i) Anything in this Agreement to the contrary
notwithstanding, in the event the Company shall at any time after the date of
this Agreement (A) declare a dividend on the Preferred Shares payable in
Preferred Shares, (B) subdivide the outstanding Preferred Shares, (C) combine
the outstanding Preferred Shares (by reverse stock split or otherwise) into a
smaller number of Preferred Shares, or (D) issue any shares of its capital stock
in a reclassification of the Preferred Shares (including any such
reclassification in connection with a consolidation or merger in which the
Company is the continuing or surviving corporation), then, in each such event,
except as otherwise provided in this Section 11 and Section 7(e) hereof: (1) the
Exercise Price in effect at the time of the record date for such dividend or of
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price thereafter shall equal the result obtained
by dividing the Exercise Price in effect immediately prior to such time by a
fraction (the "ADJUSTMENT FRACTION"), the numerator of which shall be the total
number of Preferred Shares (or shares of capital stock issued in such
reclassification of the Preferred Shares) outstanding immediately following such
time and the denominator of which shall be the total number of Preferred Shares
outstanding immediately prior to such time; provided, however, that in no event
shall the consideration to be paid upon the exercise of one Right be less than
the aggregate par value of the shares of capital stock of the Company issuable
upon exercise of such Right; and (2) the number of one-thousandths of a
Preferred Share (or share of such other capital stock) issuable upon the
exercise of each Right shall equal the number of one-thousandths of a Preferred
Share (or share of such other capital stock) as was issuable upon exercise of a
Right immediately prior to the occurrence of the event described in clauses
(A)-(D) of this Section 11(a)(i), multiplied by the Adjustment Fraction;
provided, however, that, no such adjustment shall be made pursuant to this
Section 11(a)(i) to the extent that there shall have simultaneously occurred an
event described in clause (A), (B), (C) or (D) of Section 11(n) with a
proportionate adjustment being made thereunder. Each Common Share that shall
become outstanding after an adjustment has been made pursuant to this Section
11(a)(i) shall have associated with it the number of Rights, exercisable at the
Exercise Price and for the number of one-thousandths of a Preferred Share (or
shares of such other capital stock), as one Common Share has associated with it
immediately following the adjustment made pursuant to this Section 11(a)(i).

                           (ii) Subject to Section 24 of this Agreement, in the
event a Triggering Event shall have occurred, then promptly following such
Triggering Event each holder of a Right, except as

                                      -15-

<PAGE>   19



provided in Section 7(e) hereof, shall thereafter have the right to receive for
each Right, upon exercise thereof in accordance with the terms of this Agreement
and payment of the Exercise Price in effect immediately prior to the occurrence
of the Triggering Event, in lieu of a number of one-thousandths of a Preferred
Share, such number of Common Shares of the Company as shall equal the result
obtained by multiplying the Exercise Price in effect immediately prior to the
occurrence of the Triggering Event by the number of one-thousandths of a
Preferred Share for which a Right was exercisable (or would have been
exercisable if the Distribution Date had occurred) immediately prior to the
first occurrence of a Triggering Event, and dividing that product by 50% of the
Current Per Share Market Price for Common Shares on the date of occurrence of
the Triggering Event; provided, however, that the Exercise Price and the number
of Common Shares of the Company so receivable upon exercise of a Right shall be
subject to further adjustment as appropriate in accordance with Section 11(e)
hereof to reflect any events occurring in respect of the Common Shares of the
Company after the occurrence of the Triggering Event. Notwithstanding the
foregoing provisions of this Section 11(a)(ii), the right to buy Common Shares
of the Company pursuant to Section 11(a)(ii) hereof shall not arise as a result
of any Person becoming an Acquiring Person through an acquisition of Common
Shares pursuant to a Permitted Offer.

                           (iii) In lieu of issuing Common Shares in accordance
with Section 11(a)(ii) hereof, the Company may, if a majority of the Continuing
Directors then in office determines that such action is necessary or appropriate
and not contrary to the interest of holders of Rights and, in the event that the
number of Common Shares which are authorized by the Company's Certificate of
Incorporation but not outstanding or reserved for issuance for purposes other
than upon exercise of the Rights are not sufficient to permit the exercise in
full of the Rights, or if any necessary regulatory approval for such issuance
has not been obtained by the Company, the Company shall: (A) determine the
excess of (1) the value of the Common Shares issuable upon the exercise of a
Right (the "CURRENT VALUE") over (2) the Exercise Price (such excess, the
"SPREAD") and (B) with respect to each Right, make adequate provision to
substitute for such Common Shares, upon exercise of the Rights, (1) cash, (2) a
reduction in the Exercise Price, (3) other equity securities of the Company
(including, without limitation, shares or units of shares of any series of
preferred stock which a majority of the Continuing Directors then in office has
deemed to have the same value as Common Shares (such shares or units of shares
of preferred stock are herein called "COMMON STOCK EQUIVALENTS")), except to the
extent that the Company has not obtained any necessary stockholder or regulatory
approval for such issuance, (4) debt securities of the Company, except to the
extent that the Company has not obtained any necessary stockholder or regulatory
approval for such issuance, (5) other assets or (6) any combination of the
foregoing, having an aggregate value equal to the Current Value, where such
aggregate value has been determined by a majority of the Continuing Directors
then in office based upon the advice of a nationally recognized investment
banking firm selected by a majority of the Continuing Directors then in office;
provided, however, if the Company shall not have made adequate provision to
deliver value pursuant to clause (B) above within thirty (30) days following the
later of (x) the first occurrence of a Triggering Event and (y) the date on
which the Company's right of redemption pursuant to Section 23(a) expires (the
later of (x) and (y) being referred to herein as the "SECTION 11(A)(II) TRIGGER
DATE"), then the Company shall be obligated to deliver, upon the surrender for
exercise of a Right and without requiring payment of the Exercise Price, Common
Shares (to the extent available), except to the extent that the Company has not
obtained any necessary stockholder or regulatory approval for such issuance, and
then, if necessary, cash, which shares and/or cash have an aggregate value equal
to the Spread. If a majority of the Continuing Directors then

                                      -16-

<PAGE>   20



in office shall determine in good faith that it is likely that sufficient
additional Common Shares could be authorized for issuance upon exercise in full
of the Rights or that any necessary regulatory approval for such issuance will
be obtained, the thirty (30) day period set forth above may be extended to the
extent necessary, but not more than ninety (90) days after the Section 11(a)(ii)
Trigger Date, in order that the Company may seek stockholder approval for the
authorization of such additional shares or take action to obtain such regulatory
approval (such period, as it may be extended, the "SUBSTITUTION PERIOD"). To the
extent that the Company determines that some action need be taken pursuant to
the first and/or second sentences of this Section 11(a)(iii), the Company (x)
shall provide, subject to Section 7(e) hereof, that such action shall apply
uniformly to all outstanding Rights and (y) may suspend the exercisability of
the Rights until the expiration of the Substitution Period in order to seek any
authorization of additional shares, to take any action to obtain any required
regulatory approval and/or to decide the appropriate form of distribution to be
made pursuant to such first sentence and to determine the value thereof. In the
event of any such suspension, the Company shall issue a public announcement
stating, and notify the Rights Agent, that the exercisability of the Rights has
been temporarily suspended, as well as issue a public announcement and
notification to the Rights Agent at such time as the suspension is no longer in
effect. For purposes of this Section 11(a)(iii), the value of the Common Shares
shall be the Current Per Share Market Price of the Common Shares on the Section
11(a)(ii) Trigger Date and the value of any Common Stock Equivalent shall be
deemed to have the same value as the Common Shares on such date.

                  (b) In case the Company shall, at any time after the date of
this Agreement, fix a record date for the issuance of rights, options or
warrants to all holders of Preferred Shares entitling such holders (for a period
expiring within forty-five (45) calendar days after such record date) to
subscribe for or purchase Preferred Shares or Equivalent Shares or securities
convertible into Preferred Shares or Equivalent Shares at a price per share (or
having a conversion price per share, if a security convertible into Preferred
Shares or Equivalent Shares) less than the then Current Per Share Market Price
of the Preferred Shares or Equivalent Shares on such record date, then, in each
such case, the Exercise Price to be in effect after such record date shall be
determined by multiplying the Exercise Price in effect immediately prior to such
record date by a fraction, the numerator of which shall be the number of
Preferred Shares and Equivalent Shares (if any) outstanding on such record date,
plus the number of Preferred Shares or Equivalent Shares, as the case may be,
which the aggregate offering price of the total number of Preferred Shares or
Equivalent Shares, as the case may be, to be offered or issued (and/or the
aggregate initial conversion price of the convertible securities to be offered
or issued) would purchase at such current market price, and the denominator of
which shall be the number of Preferred Shares and Equivalent Shares (if any)
outstanding on such record date, plus the number of additional Preferred Shares
or Equivalent Shares, as the case may be, to be offered for subscription or
purchase (or into which the convertible securities so to be offered are
initially convertible); provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. In case such subscription price may be paid in a
consideration part or all of which shall be in a form other than cash, the value
of such consideration shall be as determined in good faith by a majority of the
Continuing Directors then in office, 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. Preferred Shares and Equivalent Shares owned by
or held for the account of the Company shall not be deemed outstanding

                                      -17-

<PAGE>   21



for the purpose of any such computation. Such adjustment shall be made
successively whenever such a record date is fixed, and in the event that such
rights, options or warrants are not so issued, the Exercise Price shall be
adjusted to be the Exercise Price which would then be in effect if such record
date had not been fixed.

                  (c) In case the Company shall, at any time after the date of
this Agreement, fix a record date for the making of a distribution to all
holders of the Preferred Shares or of any class or series of Equivalent Shares
(including any such distribution made in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation) of
evidences of indebtedness or assets (other than a regular quarterly cash
dividend, if any, or a dividend payable in Preferred Shares) or subscription
rights, options or warrants (excluding those referred to in Section 11(b)),
then, in each such case, the Exercise Price to be in effect after such record
date shall be determined by multiplying the Exercise Price in effect immediately
prior to such record date by a fraction, the numerator of which shall be the
Current Per Share Market Price of a Preferred Share or an Equivalent Share on
such record date, less the fair market value per Preferred Share or Equivalent
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) 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 Preferred
Share or Equivalent Share, as the case may be, and the denominator of which
shall be such Current Per Share Market Price of a Preferred Share or Equivalent
Share on such record date; provided, however, that in no event shall the
consideration to be paid upon the exercise of one Right be less than the
aggregate par value of the shares of capital stock of the Company issuable upon
exercise of one Right. 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 Exercise Price shall be adjusted to be the Exercise Price which would have
been in effect if such record date had not been fixed.

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

                  (e) If as a result of an adjustment made pursuant to Section
11(a) or 13(a) hereof, the holder of any Right thereafter exercised shall become
entitled to receive any shares of capital stock other than Preferred Shares,
thereafter the number of such other shares so receivable upon exercise of any
Right and, if required, the Exercise 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 Shares contained in
Sections 11(a), 11(b), 11(c), 11(d), 11(f), 11(g), 11(h), 11(i), 11(j), 11(k)
and 11(l), and the provisions of Sections 7, 9, 10, 13 and 14 with respect to
the Preferred Shares shall apply on like terms to any such other shares.

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

                  (g) Unless the Company shall have exercised its election as
provided in Section 11(h), upon each adjustment of the Exercise Price as a
result of the calculations made in Section 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 Exercise Price, that number of Preferred
Shares (calculated to the nearest one one-hundred-thousandth of a share)
obtained by (i) multiplying (x) the number of Preferred Shares covered by a
Right immediately prior to this adjustment, by (y) the Exercise Price in effect
immediately prior to such adjustment of the Exercise Price, and (ii) dividing
the product so obtained by the Exercise Price in effect immediately after such
adjustment of the Exercise Price.

                  (h) The Company may elect on or after the date of any
adjustment of the Exercise Price as a result of the calculations made in Section
11(b) or (c) to adjust the number of Rights in substitution for any adjustment
in the number of Preferred Shares purchasable upon the exercise of a Right. Each
of the Rights outstanding after such adjustment of the number of Rights shall be
exercisable for the number of one-thousandths of a Preferred Share for which a
Right was exercisable immediately prior to such adjustment. Each Right held of
record prior to such adjustment of the number of Rights shall become that number
of Rights (calculated to the nearest one hundred-thousandth) obtained by
dividing the Exercise Price in effect immediately prior to adjustment of the
Exercise Price by the Exercise Price in effect immediately after adjustment of
the Exercise Price. The Company shall make a public announcement, with notice
thereof to the Rights Agent, 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 Exercise 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(h), the
Company shall, as promptly as practicable, cause to be distributed to holders of
record of Rights Certificates on such record date Rights Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment, or, at the option of
the Company, shall cause to be distributed to such holders of record in
substitution and replacement for the Rights Certificates held by such holders
prior to the date of adjustment, and upon surrender thereof, if required by the
Company, new Rights Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment. Rights Certificates 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 Exercise
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.

                  (i) Irrespective of any adjustment or change in the Exercise
Price or the number of Preferred Shares issuable upon the exercise of the
Rights, the Rights Certificates theretofore and thereafter issued may continue
to express the Exercise Price per one one-thousandth of a Preferred Share

                                      -19-

<PAGE>   23



and the number of one-thousandths of a Preferred Share which were expressed in
the initial Rights Certificates issued hereunder.

                  (j) Before taking any action that would cause an adjustment
reducing the Exercise Price below the par or stated value, if any, of the number
of one-thousandths of a Preferred Share issuable upon exercise of the Rights,
the Company shall take any corporate action which may, in the opinion of its
counsel, be necessary in order that the Company may validly and legally issue as
fully paid and nonassessable shares such number of one-thousandths of a
Preferred Share at such adjusted Exercise Price.

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

                  (l) Anything in this Section 11 to the contrary
notwithstanding, prior to the Distribution Date, the Company shall be entitled
to make such reductions in the Exercise Price, in addition to those adjustments
expressly required by this Section 11, as and to the extent that it in its sole
discretion shall determine to be advisable in order that any (i) consolidation
or subdivision of the Preferred or Common Shares, (ii) issuance wholly for cash
of any Preferred or Common Shares at less than the current market price, (iii)
issuance wholly for cash of Preferred or Common Shares or securities which by
their terms are convertible into or exchangeable for Preferred or Common Shares,
(iv) stock dividends or (v) issuance of rights, options or warrants referred to
in this Section 11, hereafter made by the Company to holders of its Preferred or
Common Shares shall not be taxable to such stockholders.

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

                  (n) In the event the Company shall at any time after the date
of this Agreement (A) declare a dividend on the Common Shares payable in Common
Shares, (B) subdivide the outstanding Common Shares, (C) combine the outstanding
Common Shares (by reverse stock split or otherwise) into a smaller number of
Common Shares, or (D) issue any shares of its capital stock in a
reclassification of the Common Shares (including any such reclassification in
connection with a consolidation or merger in which the Company is the continuing
or surviving corporation), then, in each such event, except as otherwise
provided in this Section 11(a) and Section 7(e) hereof: (1) each Common Share
(or shares of capital stock issued in such reclassification of the Common
Shares) outstanding

                                      -20-

<PAGE>   24



immediately following such time shall have associated with it the number of
Rights as were associated with one Common Share immediately prior to the
occurrence of the event described in clauses (A)-(D) above; (2) the Exercise
Price in effect at the time of the record date for such dividend or of the
effective date of such subdivision, combination or reclassification shall be
adjusted so that the Exercise Price thereafter shall equal the result obtained
by multiplying the Exercise Price in effect immediately prior to such time by a
fraction, the numerator of which shall be the total number of Common Shares
outstanding immediately prior to the event described in clauses (A)-(D) above,
and the denominator of which shall be the total number of Common Shares
outstanding immediately after such event; provided, however, that in no event
shall the consideration to be paid upon the exercise of one Right be less than
the aggregate par value of the shares of capital stock of the Company issuable
upon exercise of such Right; and (3) the number of one-thousandths of a
Preferred Share (or shares of such other capital stock) issuable upon the
exercise of each Right outstanding after such event shall equal the number of
one-thousandths of a Preferred Share (or shares of such other capital stock) as
were issuable with respect to one Right immediately prior to such event. Each
Common Share that shall become outstanding after an adjustment has been made
pursuant to this Section 11(n) shall have associated with it the number of
Rights, exercisable at the Exercise Price and for the number of one-thousandths
of a Preferred Share (or shares of such other capital stock), as one Common
Share has associated with it immediately following the adjustment made pursuant
to this Section 11(n). If an event occurs which would require an adjustment
under both this Section 11(n) and Section 11(a)(ii) hereof, the adjustment
provided for in this Section 11(n) shall be in addition to, and shall be made
prior to, any adjustment required pursuant to Section 11(a)(ii) hereof.

         Section 12. Certificate of Adjusted Exercise Price or Number of Shares.
Whenever an adjustment is made as provided in Sections 11 or 13 hereof, the
Company shall promptly (a) prepare a certificate setting forth such adjustment
and a brief statement of the facts and computations accounting for such
adjustment, (b) file with the Rights Agent and with each transfer agent for the
Preferred Shares a copy of such certificate and (c) mail a brief summary thereof
to each holder of a Rights Certificate in accordance with Section 26 hereof.
Notwithstanding the foregoing sentence, the failure of the Company to make such
certification or give such notice shall not affect the validity of such
adjustment or the force or effect of the requirement for such adjustment. The
Rights Agent shall be fully protected in relying on any such certificate and on
any adjustment contained therein and shall have no duty with respect to and
shall not be deemed to have knowledge of such adjustment unless and until it
shall have received such certificate.

         Section 13. Consolidation, Merger or Sale or Transfer of Assets or
                     Earning Power.

                  (a) In the event that, following a Triggering Event, directly
or indirectly:

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


                                      -21-

<PAGE>   25



                           (ii) any Person shall consolidate with the Company,
or merge with and into the Company and the Company shall be the continuing or
surviving corporation of such consolidation or merger and, in connection with
such merger, all or part of the Common Shares shall be changed into or exchanged
for stock or other securities of any other Person (or the Company); or

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

                                    then, concurrent with and in each such case,

                                    (A) 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 a price equal to the Total Exercise Price
applicable immediately prior to the occurrence of the Section 13 Event in
accordance with the terms of this Agreement, such number of validly authorized
and issued, fully paid, nonassessable and freely tradeable Common Shares of the
Principal Party (as hereinafter defined), free of any liens, encumbrances,
rights of first refusal or other adverse claims, as shall be equal to the result
obtained by dividing such Total Exercise Price by 50% of the Current Per Share
Market Price of the Common Shares of such Principal Party on the date of
consummation of such Section 13 Event, provided, however, that the Exercise
Price and the number of Common Shares of such Principal Party so receivable upon
exercise of a Right shall be subject to further adjustment as appropriate in
accordance with Section 11(e) hereof;

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

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

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

                                    (E) upon the subsequent occurrence of any
consolidation, merger, sale or transfer of assets or other extraordinary
transaction in respect of such Principal Party, each holder of a Right shall
thereupon be entitled to receive, upon exercise of a Right and payment of the
Total Exercise Price as provided in this Section 13(a), such cash, shares,
rights, warrants and other property

                                      -22-

<PAGE>   26



which such holder would have been entitled to receive had such holder, at the
time of such transaction, owned the Common Shares of the Principal Party
receivable upon the exercise of such Right pursuant to this Section 13(a), and
such Principal Party shall take such steps (including, but not limited to,
reservation of shares of stock) as may be necessary to permit the subsequent
exercise of the Rights in accordance with the terms hereof for such cash,
shares, rights, warrants and other property.

                                    (F) For purposes hereof, the "earning power"
of the Company and its Subsidiaries shall be determined in good faith by the
Company's Board of Directors on the basis of the operating earnings of each
business operated by the Company and its Subsidiaries during the three fiscal
years preceding the date of such determination (or, in the case of any business
not operated by the Company or any Subsidiary during three full fiscal years
preceding such date, during the period such business was operated by the Company
or any Subsidiary).

                  (b) For purposes of this Agreement, the term "PRINCIPAL PARTY"
shall mean:

                           (i) in the case of any transaction described in
clause (i) or (ii) of Section 13(a) hereof: (A) the Person that is the issuer of
the securities into which the Common Shares are converted in such merger or
consolidation, or, if there is more than one such issuer, the issuer the Common
Shares of which have the greatest aggregate market value of shares outstanding,
or (B) if no securities are so issued, (x) the Person that is the other party to
the merger, if such Person survives said merger, or, if there is more than one
such Person, the Person the Common Shares of which have the greatest aggregate
market value of shares outstanding or (y) if the Person that is the other party
to the merger does not survive the merger, the Person that does survive the
merger (including the Company if it survives) or (z) the Person resulting from
the consolidation; and

                           (ii) in the case of any transaction described in
clause (iii) of Section13(a) hereof, the Person that is the party receiving the
greatest portion of the assets or earning power transferred pursuant to such
transaction or transactions, or, if more than one Person that is a party to such
transaction or transactions receives the same portion of the assets or earning
power so transferred and each such portion would, were it not for the other
equal portions, constitute the greatest portion of the assets or earning power
so transferred, or if the Person receiving the greatest portion of the assets or
earning power cannot be determined, whichever of such Persons is the issuer of
Common Shares having the greatest aggregate market value of shares outstanding;

provided, however, that in any such case described in the foregoing clause
(b)(i) or (b)(ii), if the Common Shares of such Person are not at such time or
have not been continuously over the preceding 12-month period registered under
Section 12 of the Exchange Act, then (1) if such Person is a direct or indirect
Subsidiary of another Person the Common Shares of which are and have been so
registered, the term "Principal Party" shall refer to such other Person, or (2)
if such Person is a Subsidiary, directly or indirectly, of more than one Person,
the Common Shares of which are and have been so registered, the term "Principal
Party" shall refer to whichever of such Persons is the issuer of Common Shares
having the greatest aggregate market value of shares outstanding, or (3) if such
Person is owned, directly or indirectly, by a joint venture formed by two or
more Persons that are not owned, directly or indirectly by the same Person, the
rules set forth in clauses (1) and (2) above shall apply to each of the owners

                                      -23-

<PAGE>   27



having an interest in the venture as if the Person owned by the joint venture
was a Subsidiary of both or all of such joint venturers, and the Principal Party
in each such case shall bear the obligations set forth in this Section 13 in the
same ratio as its interest in such Person bears to the total of such interests.

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

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

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

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

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

                  (d) In case the "Principal Party" for purposes of Section
13(b) hereof has provision in any of its authorized securities or in its
certificate of incorporation or by-laws or other instrument governing its
corporate affairs, which provision would have the effect of (i) causing such
Principal Party to issue (other than to holders of Rights pursuant to Section 13
hereof), in connection with, or as a consequence of, the consummation of a
Section 13 Event, Common Shares or Equivalent Shares of such

                                      -24-

<PAGE>   28



Principal Party at less than the then Current Per Share Market Price thereof or
securities exercisable for, or convertible into, Common Shares or Equivalent
Shares of such Principal Party at less than such then Current Per Share Market
Price, or (ii) providing for any special payment, tax or similar provision in
connection with the issuance of the Common Shares of such Principal Party
pursuant to the provisions of Section 13 hereof, then, in such event, the
Company hereby agrees with each holder of Rights that it shall not consummate
any such transaction unless prior thereto the Company and such Principal Party
shall have executed and delivered to the Rights Agent a supplemental agreement
providing that the provision in question of such Principal Party shall have been
canceled, waived or amended, or that the authorized securities shall be
redeemed, so that the applicable provision will have no effect in connection
with or as a consequence of, the consummation of the proposed transaction.

                  (e) The Company covenants and agrees that it shall not, at any
time after the Distribution Date, effect or permit to occur any Section 13
Event, if (i) at the time or immediately after such Section 13 Event there are
any rights, warrants or other instruments or securities outstanding or
agreements in effect which would substantially diminish or otherwise eliminate
the benefits intended to be afforded by the Rights, (ii) prior to,
simultaneously with or immediately after such Section 13 Event, the stockholders
of the Person who constitutes, or would constitute, the "Principal Party" for
purposes of Section 13(b) hereof shall have received a distribution of Rights
previously owned by such Person or any of its Affiliates or Associates or (iii)
the form or nature of organization of the Principal Party would preclude or
limit the exercisability of the Rights.

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

                  (g) The provisions of this Section 13 shall similarly apply to
successive mergers or consolidations or sales or other transfers.

         Section 14. Fractional Rights and Fractional Shares.

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

                                      -25-

<PAGE>   29



Rights would have been otherwise issuable, as determined pursuant to the second
sentence of Section 1(k) hereof.

                  (b) The Company shall not be required to issue fractions of
Preferred Shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of the Rights or to
distribute certificates which evidence fractional Preferred Shares (other than
fractions that are integral multiples of one one-thousandth of a Preferred
Share). Interests in fractions of Preferred Shares in integral multiples of one
one-thousandth of a Preferred Share may, at the election of the Company, be
evidenced by depositary receipts, pursuant to an appropriate agreement between
the Company and a depositary selected by it; provided, that such agreement shall
provide that the holders of such depositary receipts shall have all the rights,
privileges and preferences to which they are entitled as beneficial owners of
the Preferred Shares represented by such depositary receipts. In lieu of
fractional Preferred Shares that are not integral multiples of one
one-thousandth of a Preferred Share, the Company shall pay to the registered
holders of Rights Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of a Preferred Share. For purposes of this Section 14(b), the current
market value of a Preferred Share shall be one thousand times the closing price
of a Common Share (as determined pursuant to the second sentence of Section 1(k)
hereof) for the Trading Day immediately prior to the date of such exercise.

                  (c) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares upon the exercise or exchange of Rights. In lieu of such fractional
Common Shares, the Company shall pay to the registered holders of Rights
Certificates at the time such Rights are exercised as herein provided an amount
in cash equal to the same fraction of the current market value of a Common
Share. For purposes of this Section 14(c), the current market value of a Common
Share shall be the closing price of a Common Share (as determined pursuant to
the second sentence of Section 1(k) hereof) for the Trading Day immediately
prior to the date of such exercise.

                  (d) The holder of a Right by the acceptance of the Right
expressly waives his or her right to receive any fractional Rights or any
fractional shares (other than fractions that are integral multiples of one
one-thousandth of a Preferred Share) upon exercise of a Right.

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

                                      -26-

this Agreement and will be entitled to specific performance of the obligations
under, and injunctive relief against actual or threatened violations of, the
obligations of any Person subject to this Agreement.

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

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

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

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

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

         Section 18. Concerning the Rights Agent.

                  (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
other disbursements incurred in the preparation, delivery, administration,
execution and any amendment 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, damage, judgment,
fine, penalty, claim demand, settlement, cost or expense, incurred without gross
negligence, bad faith or willful misconduct on the part of the Rights Agent, for
any action taken, suffered or omitted by the Rights Agent in connection with the
acceptance and administration of this Agreement, including, without limitation,
the costs and expenses of defending against any claim of

                                      -27-

<PAGE>   31



liability in the premises. In no event will the Rights Agent be liable for
special, indirect, incidental or consequential loss or damage of any kind
whatsoever (including, but not limited to, lost profits), even if the Rights
Agent has been advised of the possibility of such loss or damage.

                  (b) The Rights Agent shall be authorized and protected and
shall incur no liability for, or in respect of any action taken, suffered or
omitted by it in connection with, its acceptance and administration of this
Agreement in reliance upon any Rights Certificate or certificate for the
Preferred Shares or Common Shares or for other securities of the Company,
instrument of assignment or transfer, power of attorney, endorsement, affidavit,
letter, notice, direction, consent, certificate, statement or other paper or
document reasonably believed by it to be genuine and to be signed, executed and,
where necessary, verified or acknowledged, by the proper Person or Persons, or
otherwise upon the advice of counsel as set forth in Section 20 hereof. The
Rights Agent shall not be deemed to have notice of any action or event, and no
duties as a result thereof, unless proper notice was given as provided above.

         Section 19. Merger or Consolidation or Change of Name of Rights Agent.

                  (a) Any Person into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any Person
resulting from any merger or consolidation to which the Rights Agent or any
successor Rights Agent shall be a party, or any Person succeeding to the
shareholder services 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 Person would be eligible for
appointment as a successor Rights Agent under the provisions of Section 21
hereof. In case at the time such successor Rights Agent shall succeed to the
agency created by this Agreement, any of the Rights Certificates shall have been
countersigned but not delivered, any such successor Rights Agent may adopt the
countersignature of the predecessor Rights Agent and deliver such Rights
Certificates so countersigned; and in case at that time any of the Rights
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Rights Certificates either in the name of the predecessor
Rights Agent or in the name of the successor Rights Agent; and in all such cases
such Rights Certificates shall have the full force provided in the Rights
Certificates and in this Agreement.

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

         Section 20. Duties of Rights Agent. The Rights Agent undertakes only
the duties and obligations expressly 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:


                                      -28-

<PAGE>   32



                  (a) The Rights Agent may consult with legal counsel (who may
be legal counsel for the Company), and the advice or opinion of such counsel
shall be full and complete authorization and protection to the Rights Agent, and
the Rights Agent shall incur no liability for or in respect of, any action
taken, suffered or omitted by it in good faith and in accordance with such
advice or opinion.

                  (b) Whenever in the performance of its duties under this
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter (including, without limitation, the identity of any Acquiring Person and
the determination of Current Per Share Market Price) be proved or established by
the Company prior to taking, suffering or omitting any action hereunder, such
fact or matter (unless other evidence in respect thereof be herein specifically
prescribed) may be deemed to be conclusively proved and established by a
certificate signed by any one of the Chairman of the Board, the Chief Executive
Officer, the President, any Vice President, the Chief Financial Officer, the
Secretary or any Assistant Secretary of the Company and delivered to the Rights
Agent; and such certificate shall be full authorization and protection to the
Rights Agent and the Rights Agent shall incur no liability for or in respect of,
any action taken, omitted or suffered in good faith by it under the provisions
of this Agreement in reliance upon such certificate.

                  (c) The Rights Agent shall be liable hereunder to the Company
and any other Person only for its own 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 (except its countersignature thereof) or be required to
verify the same, but all such statements and recitals are and shall be deemed to
have been made by the Company only.

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

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

<PAGE>   33



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

                  (h) The Rights Agent and any stockholder, affiliate, 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 Person
or 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 or any other Person
resulting from any such act, default, neglect or misconduct, absent gross
negligence, bad faith or willful misconduct.

                  (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 it believes that repayment of such funds or adequate indemnification
against such risk or liability is not reasonably assured to it.

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

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon thirty (30) days' notice in writing mailed to the Company and to each
transfer agent of the Preferred Shares and the Common Shares by

                                      -30-

<PAGE>   34



registered or certified mail, and to the holders of the Rights Certificates by
first-class mail. The Company may remove the Rights Agent or any successor
Rights Agent upon thirty (30) days' notice in writing, mailed to the Rights
Agent or successor Rights Agent, as the case may be, and to each transfer agent
of the Preferred Shares and the Common Shares by registered or certified mail,
and to the holders of the Rights Certificates by first-class mail. If the Rights
Agent shall resign or be removed or shall otherwise become incapable of acting,
the Company shall appoint a successor to the Rights Agent. If the Company shall
fail to make such appointment within a period of thirty (30) days after giving
notice of such removal or after it has been notified in writing of such
resignation or incapacity by the resigning or incapacitated Rights Agent or by
the holder of a Rights Certificate (who shall, with such notice, submit his or
her Rights Certificate for inspection by the Company), then the registered
holder of any Rights Certificate may apply to any court of competent
jurisdiction for the appointment of a new Rights Agent. Any successor Rights
Agent, whether appointed by the Company or by such a court, shall be (i) a
Person organized and doing business under the laws of the United States or of
any state of the United States, in good standing, which is subject to
supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $50 million or (ii) an affiliate of such a Person. After appointment, the
successor Rights Agent shall be vested with the same powers, rights, duties and
responsibilities as if it had been originally named as Rights Agent without
further act or deed; but the predecessor Rights Agent shall deliver and transfer
to the successor Rights Agent any property at the time held by it hereunder, and
execute and deliver any further assurance, conveyance, act or deed necessary for
the purpose. Not later than the effective date of any such appointment, the
Company shall file notice thereof in writing with the predecessor Rights Agent
and each transfer agent of the Preferred Shares and the Common Shares, and mail
a notice thereof in writing to the registered holders of the Rights
Certificates. Failure to give any notice provided for in this Section 21,
however, or any defect therein, shall not affect the legality or validity of the
resignation or removal of the Rights Agent or the appointment of the successor
Rights Agent, as the case may be.

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

                                      -31-

<PAGE>   35



available special tax treatment and (ii) no such Rights Certificate shall be
issued if, and to the extent that, appropriate adjustment shall otherwise have
been made in lieu of the issuance thereof.

         Section 23. Redemption.

                  (a) The Company may, at its option and with the approval of
the Board of Directors, at any time prior to the earlier of (i) such time as any
Person becomes an Acquiring Person or (ii) the Close of Business on the Final
Expiration Date, redeem all but not less than all the then outstanding Rights at
a redemption price of $0.01 per Right, appropriately adjusted to reflect any
stock split, stock dividend or similar transaction occurring after the date
hereof (such redemption price being herein referred to as the "REDEMPTION
PRICE") and the Company may, at its option, pay the Redemption Price either in
Common Shares (based on the Current Per Share Market Price thereof at the time
of redemption) or cash; provided, however, that the Board of Directors of the
Company may authorize redemption of the Rights only if there are Continuing
Directors then in office and such Continuing Directors have concurred with such
authorization. Such redemption of the Rights by the Company may be made
effective at such time, on such basis and with such conditions as the Board of
Directors in its sole discretion may establish. The date on which the Board of
Directors or the Company elects to make the redemption effective shall be
referred to as the "REDEMPTION DATE."

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

         Section 24. Exchange.

                  (a) Subject to applicable laws, rules and regulations, and
subject to subsection 24(c) below, the Company may, at its option, by action of
its Board of Directors, at any time after the occurrence of a Triggering Event,
exchange all or part of the then outstanding and exercisable Rights (which shall
not include Rights that have become null and void pursuant to the provisions of
Section 7(e) hereof) for Common Shares at an exchange ratio of one Common Share
per Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such

                                      -32-

<PAGE>   36



exchange ratio being hereinafter referred to as the "EXCHANGE RATIO").
Notwithstanding the foregoing, such Board of Directors shall not be empowered to
effect such exchange at any time after any Person (other than the Company, any
Subsidiary of the Company, any employee benefit plan of the Company or any such
Subsidiary, or any Person organized, appointed or established by the Company for
or pursuant to the terms of any such plan), together with all Affiliates and
Associates of such Person, becomes the Beneficial Owner of 50% or more of the
Common Shares then outstanding.

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

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

                                      -33-

<PAGE>   37



                  (d) The Company shall not be required to issue fractions of
Common Shares or to distribute certificates which evidence fractional Common
Shares. In lieu of such fractional Common Shares, there shall be paid to the
registered holders of the Rights Certificates with regard to which such
fractional Common Shares would otherwise be issuable, an amount in cash equal to
the same fraction of the current market value of a whole Common Share (as
determined pursuant to the second sentence of Section 1(k) hereof).

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

                  (f) Immediately upon the action of the Board of Directors
ordering the exchange of any Rights pursuant to subsection 24(e) of this Section
24 and without any further action and without any notice, the right to exercise
such Rights shall terminate and the only right thereafter of a holder of such
Rights shall be to receive that number of rights in exchange therefor as has
been determined by the Board of Directors in accordance with subsection 24(e)
above. The Company shall give public notice of any such exchange (with prompt
notice thereof to the Rights Agent); provided, however, that the failure to
give, or any defect in, such notice shall not affect the validity of such
exchange. The Company shall mail a notice of any such exchange to all of the
holders of such Rights at their last addresses as they appear upon the registry
books of the transfer agent for the Common Shares of the Company. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange will state the
method by which the exchange of the Rights will be effected.

         Section 25. Notice of Certain Events.

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

                  (b) In case any Triggering Event or Section 13 Event shall
occur, then, in any such case, the Company shall as soon as practicable
thereafter give to the Rights Agent and to each holder of a Rights Certificate,
in accordance with Section 26 hereof, a notice of the occurrence of such event,
which shall specify the event and the consequences of the event to holders of
Rights under Sections 11(a)(ii) and 13 hereof.

         Section 26. Notices. Notices or demands authorized by this Agreement to

to or on the Company shall be sufficiently given or made if sent by first-class
mail, postage prepaid, addressed (until another address is filed in writing with
the Rights Agent) as follows:

respect without the approval of any holders of Rights and the Rights Agent
shall, if the Company so directs and such supplement or amendment does not
change or increase the Rights Agent's duties, liabilities or obligations,
execute such supplement or amendment; provided that any such supplement or
amendment shall be effective only if there are Continuing Directors then in
office and a majority of such Continuing Directors shall have concurred in such

(iii) shorten or lengthen any time period hereunder or (iv) change or supplement

desirable and that shall not adversely affect the interests of the Rights Agent

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

such lengthening is for the purpose of protecting, enhancing or clarifying the
rights of, and/or the benefits to, the holders of Rights (other than an
Acquiring Person or an Affiliate or Associate of an Acquiring Person). Upon the
delivery of a certificate from an appropriate officer of the Company that states
that the proposed supplement or amendment is in compliance with the terms of
this Section 27, and, if requested by the Rights Agent in connection with a
supplement or amendment after the occurrence of the Distribution Date, an
opinion of counsel, the Rights Agent shall execute such supplement or amendment.
Prior to the Distribution Date, the interests of the holders of Rights shall be
deemed coincident with the interests of the holders of Common Shares.

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

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 (or, where specifically provided for
herein, the Continuing Directors) shall have the exclusive power and authority
to administer this Agreement and to exercise all rights and powers specifically
granted to the Board, or the Company (or, where specifically provided for
herein, the Continuing Directors), or as may be necessary or advisable in the
administration of this Agreement, including, without limitation, the right and
power to (i) interpret the provisions of this Agreement and (ii) make all
determinations deemed necessary or advisable for the administration of this
Agreement (including a determination to redeem or not redeem the Rights or to
amend the Agreement). All such actions, calculations, interpretations and
determinations (including, for purposes of clause (y) below, all omissions with

specifically provided for herein, the Continuing Directors) in good faith, shall
(x) be final, conclusive and binding on the Company, the Rights Agent, the
holders of the Rights Certificates and all other Persons and (y) not subject the
Board or the Continuing Directors to any liability to the holders of the Rights.
The Rights Agent is entitled to always assume that the Company's Board of
Directors acted in good faith and shall be fully protected and incur no
liability in reliance thereon.

         Section 30. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and

claim under this Agreement; but this Agreement shall be for the sole and
exclusive benefit

Certificates (and, prior to the Distribution Date, the Common Shares).

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

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

shall be governed by and construed in accordance with the laws of the State of
New York applicable to contracts made and to be performed entirely within such
State.

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

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

                                AND PRIVILEGES OF
                     SERIES A PARTICIPATING PREFERRED STOCK
                                 OF CYMER, INC.


         The undersigned, Robert P. Akins and William A. Angus, III do hereby
certify:

         1. That they are the duly elected and acting President and Secretary,
respectively, of Cymer, Inc., a Nevada corporation (the "CORPORATION").

         2. That pursuant to the authority conferred upon the Board of Directors
by the Certificate of Incorporation of the said Corporation, the said Board of
Directors on February 13, 1998 adopted the following resolution creating a
series of 100,000 shares of Preferred Stock designated as Series A Participating
Preferred Stock:

         "RESOLVED, that pursuant to the authority vested in the Board of
Directors of the corporation by the Restated Certificate of Incorporation, the
Board of Directors does hereby provide for the issue of a series of Preferred
Stock of the Corporation and does hereby fix and herein state and express the
designations, powers, preferences and relative and other special rights and the
qualifications, limitations and restrictions of such series of Preferred Stock
as follows:

         Section 1. Designation and Amount. The shares of such series shall be
designated as "SERIES A PARTICIPATING PREFERRED STOCK." The Series A
Participating Preferred Stock shall have a par value of $.001 per share, and the
number of shares constituting such series shall be 100,000.

         Section 2. Proportional Adjustment. In the event the Corporation shall
at any time after the issuance of any share or shares of Series A Participating
Preferred Stock (i) declare any dividend on Common Stock of the Corporation
("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 Corporation shall
simultaneously effect a proportional adjustment to the number of outstanding
shares of Series A Participating Preferred Stock.

         Section 3. Dividends and Distributions.

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


<PAGE>   43



Participating Preferred Stock, in an amount per share (rounded to the nearest
cent) equal to 1,000 times the aggregate per share amount of all cash dividends,
and 1,000 times the aggregate per share amount (payable in kind) of all non-cash
dividends or other distributions other than a dividend payable in shares of
Common Stock or a subdivision of the outstanding shares of Common Stock (by
reclassification or otherwise), declared on the Common Stock since the
immediately preceding Quarterly Dividend Payment Date, or, with respect to the
first Quarterly Dividend Payment Date, since the first issuance of any share or
fraction of a share of Series A Participating Preferred Stock.

                  (b) The Corporation shall declare a dividend or distribution
on the Series A Participating Preferred Stock as provided in paragraph (a) above
immediately after it declares a dividend or distribution on the Common Stock
(other than a dividend payable in shares of Common Stock).

                  (c) Dividends shall begin to accrue on outstanding shares of
Series A Participating Preferred Stock from the Quarterly Dividend Payment Date
next preceding the date of issue of such shares of Series A Participating
Preferred Stock, unless the date of issue of such shares is prior to the record
date for the first Quarterly Dividend Payment Date, in which case dividends on
such shares shall begin to accrue from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date after
the record date for the determination of holders of shares of Series A
Participating Preferred Stock entitled to receive a quarterly dividend and
before such Quarterly Dividend Payment Date, in either of which events such
dividends shall begin to accrue from such Quarterly Dividend Payment Date.
Accrued but unpaid dividends shall not bear interest. Dividends paid on the
shares of Series A Participating Preferred Stock in an amount less than the
total amount of such dividends at the time accrued and payable on such shares
shall be allocated pro rata on a share-by-share basis among all such shares at
the time outstanding. The Board of Directors may fix a record date for the
determination of holders of shares of Series A Participating Preferred Stock
entitled to receive payment of a dividend or distribution declared thereon,
which record date shall be no more than 30 days prior to the date fixed for the
payment thereof.

         Section 4. Voting Rights. The holders of shares of Series A
Participating Preferred Stock shall have the following voting rights:

                  (a) Each share of Series A Participating Preferred Stock shall
entitle the holder thereof to 1,000 votes on all matters submitted to a vote of
the stockholders of the Corporation.

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

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

         Section 5. Certain Restrictions.

                  (a) The Corporation shall not declare any dividend on, make
any distribution on, or redeem or purchase or otherwise acquire for
consideration any shares of Common Stock after the first issuance of a share or
fraction of a share of Series A Participating Preferred Stock unless
concurrently therewith it shall declare a dividend on the Series A Participating
Preferred Stock as required by Section 3 hereof.

                  (b) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Participating Preferred Stock as provided
in Section 3 are in arrears, thereafter and until all accrued and unpaid
dividends and distributions, whether or not declared, on shares of Series A
Participating Preferred Stock outstanding shall have been paid in full, the
Corporation shall not

                           (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 Participating Preferred Stock;

                           (ii) declare or pay dividends on, 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 Series A Participating
Preferred Stock, except dividends paid ratably on the Series A Participating
Preferred Stock and all such parity stock on which dividends are payable or in
arrears in proportion to the total amounts to which the holders of all such
shares are then entitled;

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

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

                  (c) The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation could, under paragraph (a) of
this Section 5, purchase or otherwise acquire such shares at such time and in
such manner.

<PAGE>   45



         Section 6. Reacquired Shares. Any shares of Series A Participating
Preferred Stock purchased or otherwise acquired by the Corporation in any manner
whatsoever shall be retired and canceled promptly after the acquisition thereof.
All such shares shall upon their cancellation become authorized but unissued
shares of Preferred Stock and may be reissued as part of a new series of
Preferred Stock to be created by resolution or resolutions of the Board of
Directors, subject to the conditions and restrictions on issuance set forth
herein and, in the Restated Certificate of Incorporation, as then amended.

         Section 7. Liquidation, Dissolution or Winding Up. Upon any
liquidation, dissolution or winding up of the Corporation, the holders of shares
of Series A Participating Preferred Stock shall be entitled to receive an
aggregate amount per share equal to 1000 times the aggregate amount to be
distributed per share to holders of shares of Common Stock plus an amount equal
to any accrued and unpaid dividends on such shares of Series A Participating
Preferred Stock.

         Section 8. Consolidation, Merger, etc. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Participating Preferred Stock shall at the same time be similarly
exchanged or changed in an amount per share 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.

         Section 9. No Redemption. The shares of Series A Participating
Preferred Stock shall not be redeemable.

         Section 10. Ranking. The Series A Participating Preferred Stock shall
rank junior to all other series of the Corporation's Preferred Stock as to the
payment of dividends and the distribution of assets, unless the terms of any
such series shall provide otherwise.

         Section 11. Amendment. The Restated Certificate of Incorporation of the
Corporation shall not be further amended in any manner which would materially
alter or change the powers, preference or special rights of the Series A
Participating Preferred Stock so as to affect them adversely without the
affirmative vote of the holders of a majority of the outstanding shares of
Series A Participating Preferred Stock, voting separately as a class.

         Section 12. Fractional Shares. Series A Participating Preferred Stock
may be issued in fractions of a share which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of all
other rights of holders of Series A Participating Preferred Stock.

Transfer of Rights;             of one Right for each share of Cymer, Inc. 
Rights Certificate:             Common Stock outstanding.  Prior to the
                                Distribution Date referred to below, the Rights
                                will be evidenced by and trade with the
                                certificates for the Common Stock. After the
                                Distribution Date, Cymer, Inc. (the "COMPANY")
                                will mail Rights certificates to the Company's
                                stockholders and the Rights will become
                                transferable apart from the Common Stock.

Distribution Date:              Rights will separate from the Common Stock and
                                become exercisable following (a) the tenth day
                                after a person or group acquires beneficial
                                ownership of 15% or more of the Company's Common
                                Stock or (b) the tenth business day (or such

                                Board of Directors) after a person or group
                                announces a tender or exchange offer, the
                                consummation of which would result in ownership
                                by a person or group of 15% or more of the
                                Company's Common Stock.

Preferred Stock                 After the Distribution Date, each Right will
Purchasable Upon                entitle the holder to purchase for $100.00 (the 
Exercise of Rights:             "EXERCISE PRICE"), a fraction of a share
                                of the Company's Preferred Stock with
                                economic terms similar to that of one
                                share of the Company's Common Stock.

Flip-In:                        If an acquiror (an "ACQUIRING PERSON") obtains
                                15% or more of the Company's Common Stock then
                                each Right (other than Rights owned by an
                                Acquiring Person or its affiliates) will entitle
                                the holder thereof to purchase, for the Exercise
                                Price, a number of shares of the Company's
                                Common Stock having a then current market value
                                of twice the Exercise Price.

Flip-Over:                      If, after an Acquiring Person obtains 15% or
                                more of the Company's Common Stock, (a) the
                                Company merges into another entity, (b) an
                                acquiring entity merges into the Company or (c)
                                the Company sells more than 50% of the Company's
                                assets or earning power, then each Right (other
                                than Rights owned by an Acquiring Person or its
                                affiliates) will entitle the holder thereof to
                                purchase, for the Exercise Price, a number of
                                shares of Common Stock of the person engaging in
                                the transaction having a then current market
                                value of twice the Exercise Price.

                                the Company at an exchange ratio of one share of
                                Common Stock per Right (subject to adjustment).

Amendment of                    The terms of the Rights and the Rights Agreement
Terms of Rights:                 may be amended in any respect without the 
                                consent of the Rights holders on or prior
                                to the Distribution Date; thereafter, the terms
                                of the Rights and the Rights Agreement may be
                                amended without the consent of the Rights
                                holders in order to cure any ambiguities or to
                                make changes which do not adversely affect the
                                interests of the Rights Agent or Rights holders
                                (other than the Acquiring Person).

Voting Rights:                  Rights will not have any voting rights.

Provisions:                     customary anti-dilution provisions.

Taxes:                          The Rights distribution should not be taxable
                                for federal income tax purposes. However,
                                following an event which renders the Rights
                                exercisable or upon redemption of the Rights,
                                stockholders may recognize taxable income.

The foregoing is a summary of certain principal terms of the Stockholder Rights
Plan only and is qualified in its entirety by reference to the detailed terms of
the Rights Agreement dated as of February 13, 1998, between the Company and the
Rights Agent.

THE RIGHTS REPRESENTED HEREBY MAY BECOME NULL AND VOID IN THE
CIRCUMSTANCES SPECIFIED IN SECTION 7(e) OF THE RIGHTS AGREEMENT BETWEEN
CYMER, INC. AND CHASEMELLON SHAREHOLDER SERVICES, L.L.C. DATED AS OF
FEBRUARY 13, 1998.
