Item 5. Other Events
- --------------------

Effective as of April 14, 1998, the Board of Directors of Sequent Computer
Systems, Inc. (the "Company") declared a dividend of one Right for each
outstanding share of Common Stock of the Company to shareholders of record at
the close of business on April 29, 1998. Each Right entitles the registered
holder to purchase from the Company one one-hundredth of a share of Series A
Preferred Shares (the "Preferred Shares") at a Purchase Price of $130, subject
to adjustment. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and ChaseMellon
Shareholder Services L.L.C., as Rights Agent.

     Initially, the Rights will be attached to the certificates representing
outstanding shares of Common Stock, and no separate Rights Certificates will be
distributed. The Rights will separate from the Common Stock and a Distribution
Date will occur upon the earlier of (i) ten days following a public announcement
that (A) a person or group of affiliated or associated persons has acquired, or
obtained the right to acquire from shareholders, beneficial ownership of 15
percent or more of the outstanding Common Stock or (B) the Board of Directors of
the Company shall declare any person to be an Adverse Person (as described
below) (each, an "Acquiring Person"), or (ii) ten business days following the
commencement of a tender offer or exchange offer that would result in a person
or group beneficially owning 15 percent or more of such outstanding Common
Stock, as such periods may be extended pursuant to the Rights Agreement.

     An Adverse Person is any person declared to be an Adverse Person by the
Board of Directors upon a determination that such person, alone or together with
its affiliates and associates, has become the beneficial owner of an amount of
Common Stock which the Board of Directors determines to be substantial (which
amount shall be more than 10% of the Common Stock then outstanding) and a
determination by at least a majority of the Board of Directors who are not
officers of the Company, after reasonable inquiry and investigation, including
consultation with such persons as such directors shall deem appropriate, that
(i) such beneficial ownership by such person is intended to cause the Company to
repurchase the Common Stock beneficially owned by such person or to cause
pressure on the Company to take action or enter into a transaction or series of
transactions intended to provide such person with short-term financial gain
under circumstances where the Board of Directors determines that the best
long-term interests of the Company and its shareholders would not be served by
taking such action or entering into such transactions or series of transactions
at that time or (ii) such beneficial ownership is causing or reasonably likely
to cause a material adverse impact (including, but not limited to, impairment of
relationships with customers or impairment of the Company's ability to maintain
its competitive position) on the business or prospects of the Company.

     Until the Distribution Date, (i) the Rights will be evidenced by and will
be transferred with and only with such Common Stock certificates, (ii) new
Common Stock certificates

                                        2
<PAGE>
issued after April 29, 1998, will contain a legend incorporating the Rights
Agreement by reference, and (iii) the surrender for transfer of any certificate
for Common Stock will also constitute the transfer of the Rights associated with
the Common Stock represented by such certificate.

     The Rights are not exercisable until the Distribution Date and will expire
at the close of business on April 14, 2008, unless earlier redeemed by the
Company as described below.

     As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of the Common Stock as of the close of
business on the Distribution Date, and thereafter, the separate Rights
Certificates alone will represent the Rights. Except as otherwise determined by
the Board of Directors, only Common Stock issued prior to the time the Rights
become exercisable or issued upon exercise or conversion of rights, warrants,
options or convertible securities issued prior to the time the Rights become
exercisable will be issued with Rights.

     In the event that any person becomes an Acquiring Person, each holder of a
Right shall thereafter have the right to receive, upon exercise, in lieu of
Preferred Shares, Common Stock of the Company (or, in certain circumstances,
cash, property or other securities of the Company) having a value equal to two
times the exercise price of the Right. However, Rights are not exercisable as
described in this paragraph until such time as the Rights are no longer
redeemable by the Company as set forth below. Notwithstanding any of the
foregoing, if any person becomes an Acquiring Person all Rights that are, or
(under certain circumstances specified in the Rights Agreement) were,
beneficially owned by an Acquiring Person will become null and void.

     For example, at an exercise price of $130 per Right, each Right not owned
by the Acquiring Person (or by certain related parties or transferees) following
the event set forth in the preceding paragraph would entitle its holder to
purchase $260 worth of Common Stock (or other consideration, as noted above) for
$130. Assuming that the Common Stock had a per share value of $20 at such time,
the holder of each valid Right would be entitled to purchase thirteen shares of
Common Stock for $130.

     In the event that, at any time following the Distribution Date, (i) the
Company is acquired in a merger or other business combination transaction in
which the Company is not the surviving corporation or in which the Common Stock
are exchanged for stock or other securities or property, or (ii) 50 percent or
more of the Company's assets or earning power is sold or transferred, each
holder of a Right (except Rights which previously have been voided as set forth
above) shall thereafter have the right to receive, upon exercise, common stock
of the acquiring company having a value equal to two times the exercise price of
the Right.

     The Purchase Price payable, and the number of one one-hundredths of a share
of Preferred Shares or other securities or property issuable upon exercise of
the Rights are

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

     With certain exceptions, no adjustment in the Purchase Price or the number
of Preferred Shares issuable upon exercise of a Right will be required until
cumulative adjustments would require an increase or decrease of at least 1
percent. No fractional Preferred Shares will be issued (other than fractions
which are integral multiples of one one-hundredth of a share of Preferred
Shares) and, in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading date prior to the date
of exercise.

     At any time until a determination that any person is an Adverse Person or
ten days (or longer if extended pursuant to the terms of the Rights Agreement)
after a person otherwise becomes an Acquiring Person, the Company may redeem the
Rights in whole, but not in part, at a price of $.001 per Right (payable in
cash, Common Stock or other consideration), appropriately adjusted to reflect
any stock split, stock dividend or similar transaction occurring after the date
hereof. Immediately upon the action of the Board of Directors ordering
redemption of the Rights, the Rights will terminate and the only right of the
holders of Rights will be to receive the $.001 redemption price.

     At any time after a person becomes an Acquiring Person, the Board of
Directors of the Company may exchange the Rights (other than Rights owned by
such person or group which become void), in whole or in part, at an exchange
ratio of one share of Common Stock, or one one-hundredth of a share of Preferred
Shares (or of a share of a class or series of the Company's preferred stock
having equivalent rights, preferences and privileges), per Right (subject to
adjustment).

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

     The Preferred Shares will be non-redeemable. The Preferred Shares may rank
on a lower priority in respect of the preference as to dividends and the
distribution of assets with other classes or series of the Company's preferred
shares. Each Preferred Share will be

                                        4
<PAGE>
     entitled to an aggregate of 100 times the cash and non-cash (payable in
kind) dividends and distributions (other than dividends and distributions
payable in Common Shares) declared on the Company's Common Stock. In the event
of liquidation, the holders of Preferred Shares will be entitled to receive a
liquidation payment in an amount equal to 100 times the payment made per share
of Common Stock, plus an amount equal to declared and unpaid dividends and
distributions thereon. In the event of any merger, consolidation or other
transaction in which Common Stock is exchanged, each Preferred Share will be
entitled to receive 100 times the amount received per share of Common Stock. The
dividend and liquidation rights of the Preferred Stock are protected by
antidilution provisions. Each Preferred Share will be entitled to 100 votes
(subject to certain adjustments) on all matters submitted to the shareholders.

     A copy of the Rights Agreement is available free of charge from the Rights
Agent. This summary description of the Rights does not purport to be complete
and is qualified in its entirety by reference to the Rights Agreement, which is
incorporated herein by reference.

                                RIGHTS AGREEMENT


     RIGHTS AGREEMENT, dated as of April 14, 1998 (the "Agreement"), between
SEQUENT COMPUTER SYSTEMS, INC., an Oregon corporation (the "Company"), and
ChaseMellon Shareholder Services L.L.C. (the "Rights Agent").

                                   WITNESSETH

     WHEREAS, effective as of April 14, 1998, the Board of Directors of the
Company authorized and declared a dividend of one Right for each share of Common
Stock (as such terms are hereinafter defined) of the Company outstanding on
April 29, 1998 (the "Record Date"), and has authorized the issuance of one Right
with respect to each share of Common Stock issued by the Company between the
Record Date and the earliest of the Distribution Date, the Redemption Date or
the Final Expiration Date (as such terms are hereinafter defined), with each
Right initially representing the right to purchase one one-hundredth of a share
of Preferred Stock (as hereinafter defined) having the rights, powers and
preferences set forth in the form of Amendment to the Company's Articles of
Incorporation as amended attached hereto as Exhibit A, upon the terms and
subject to the conditions herein set forth (the "Rights");

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

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

          (a) "Acquiring Person" shall mean (i) any Person (as such term is
hereinafter defined) who or which, together with all Affiliates and Associates
(as such terms are hereinafter, defined) of such Person, shall become the
Beneficial Owner (as such term is hereinafter defined) of 15% or more of the
shares of Common Stock then outstanding or (ii) any Person who is an Adverse
Person (as such term is hereinafter defined); provided, however, that an
Acquiring Person shall not include the Company, any Subsidiary (as such term is
hereinafter defined) of the Company or any employee benefit plan of the Company
or of any Subsidiary of the Company, or any entity holding shares of Common
Stock for or pursuant to the terms of any such plan. Notwithstanding the
foregoing, no Person shall be deemed to be an "Acquiring Person" either (i) as
the result of an acquisition of Common Stock by the Company which, by reducing
the number of shares outstanding, increases the proportionate number of shares
Beneficially Owned by such Person to 15% or more of the Common Stock of the
Company then outstanding; provided, however, that if a Person shall become the
Beneficial Owner of 15% or more of the Common Stock then outstanding by reason
of share purchases by the Company and shall, after such share purchases by the
Company, become the Beneficial Owner of any additional shares of Common Stock,
then such Person shall be deemed to be an "Acquiring Person," or (ii) if the
Board of Directors
<PAGE>
of the Company determines in good faith that a Person who would otherwise be an
"Acquiring Person," as defined pursuant to the foregoing provisions of this
paragraph (a), has become such inadvertently, and such Person divests as
promptly as practicable a sufficient number of shares of Common Stock so that
such Person would no longer be an "Acquiring Person," as defined pursuant to the
foregoing provisions of this paragraph (a).

          (b) "Act" shall mean the Securities Act of 1933, as amended.

          (c) "Adverse Person" shall mean any Person declared to be an Adverse
Person by the Board of Directors of the Company upon a determination that such
Person, alone or together with its Affiliates and Associates, has, at any time
after the date of this Agreement, become the Beneficial Owner of an amount of
Common Stock which the Board of Directors determines to be substantial (which
amount shall be more than 10% of the shares of Common Stock then outstanding)
and a determination by at least a majority of the Board of Directors who are not
officers of the Company, after reasonable inquiry and investigation, including
consultation with such persons as such directors shall deem appropriate, that
(1) such beneficial ownership by such Person is intended to cause the Company to
repurchase the Common Stock beneficially owned by such Person or to cause
pressure on the Company to take action or enter into a transaction or series of
transactions intended to provide such Person with short-term financial gain
under circumstances where the Board of Directors determines that the best
long-term interests of the Company and its shareholders would not be served by
taking such action or entering into such transactions or series of transactions
at that time, or (2) such beneficial ownership is causing or reasonably likely
to cause a material adverse impact (including, but not limited to, impairment of
relationships with customers or impairment of the Company's ability to maintain
its competitive position) on the business or prospects of the Company.

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

          (e) "Agreement" shall mean this Rights Agreement.

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

               (i) which such Person or any of such Person's Affiliates or
     Associates, directly or indirectly, has the power to vote or dispose of,
     including pursuant to any agreement, arrangement or understanding, whether
     or not in writing;

               (ii) which such Person or any of such Person's Affiliates or
     Associates, directly or indirectly, has the right to acquire voting or
     dispositive power over (whether such right is exercisable immediately or
     only after the passage of time) pursuant to any agreement, arrangement or
     understanding (whether or not in writing),

                                       2
<PAGE>
     or upon the exercise of conversion rights, exchange rights, rights,
     warrants or options, or otherwise; or

               (iii) which are beneficially owned, directly or indirectly, by
     any other Person (or any Affiliate or Associate thereof) with which such
     Person (or any of such Person's Affiliates or Associates) has any agreement
     arrangement or understanding, whether or not in writing, for the purpose of
     acquiring, holding, voting or disposing of any securities of the Company;

provided, however, that nothing in this paragraph (f) shall cause a person to be
the "Beneficial Owner" of, or to "beneficially own," (A) any securities that may
be issued on the exercise of Rights, (B) any security if the agreement,
arrangement or understanding to vote such security arises solely from a
revocable proxy or consent given to such Person in response to a public proxy or
consent solicitation made pursuant to, and in accordance with, the applicable
rules and regulations of the Exchange Act, (C) securities tendered pursuant to a
tender or exchange offer made by or on behalf of such Person or any of such
Person's Affiliates or Associates until such tendered securities are accepted
for purchase or exchange, or (D) any securities acquired by a Person engaged in
business as an underwriter of securities through such Person's participation in
good faith in a firm commitment underwriting until the expiration of 40 days
after the date of such acquisition. For all purposes of this Agreement, any
calculation of the number of shares of Common Stock outstanding at any
particular time for purposes of determining the particular percentage of such
outstanding shares of Common Stock of which any Person is the Beneficial Owner
shall be made in accordance with the last sentence of Rule 13d-3(d)(1)(i) of the
General Rules and Regulations under the Exchange Act.

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

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

          (i) "Common Stock" shall mean the Common Stock, $.01 par value, of the
Company. The term "common stock" when used with reference to any Person other
than the Company shall mean the capital stock (or equity interest) with the
greatest voting power of such other Person together with all rights and benefits
(however denominated or constituted) relating to such common stock (including,
without limitation any rights or warrants to acquire additional shares of such
common stock or other securities or assets, or to participate in any trust for
the benefit of holders of such shares, or to share in the benefits of any
agreements or other arrangements for the benefit of such holders), whether or
not such rights are yet exercisable, and together with any other securities
which are represented

                                       3
<PAGE>
by the certificates for such common stock or are transferred in connection with

          (k) "Current Per Share Market Price" shall have the meaning set forth
in Section 11(d).

          (l) "Current Value" shall have the meaning set forth in Section

          (m) "Distribution Date" shall have the meaning set forth in Section

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

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

                                       5
<PAGE>
of Rule 14d-2(a) of the General Rules and Regulations under the Exchange Act, if
upon consummation thereof, such Person would be the Beneficial Owner of 15
percent or more of the shares of Common Stock then outstanding (the earliest of
(i) and (ii) being herein referred to as the "Distribution Date"), (w) the
Rights will be evidenced by the certificates for the Common Stock registered in
the names of the holders of the Common Stock (which certificates shall also be
deemed to be certificates for Rights) and not by separate Rights Certificates,
(x) the Rights and the right to receive Rights Certificates will be transferable
only in connection with the transfer of the underlying Common Stock and any
transfer of Common Stock shall also constitute the transfer of the associated
Rights represented by the same certificate, (y) in the event the Company
purchases or acquires any Common Stock after the Record Date but prior to the
Distribution Date, any Rights associated with such acquired Common Stock shall
be deemed canceled and retired so that the Company shall not be entitled to

Record Date but prior to the earliest of the Distribution Date, the Redemption
Date or the Final Expiration Date, the Company shall issue one Right for each
such newly issued share of Common stock (subject to adjustment as provided in
Section 11(h)) which Right shall be evidenced by the certificate for the
associated share of Common Stock. As soon as practicable after the Distribution
Date, the Company will prepare and execute, the Rights Agent will countersign,
and the Company will send or cause to be sent (and the Rights Agent will, if
requested, send) by first-class, postage-prepaid mail, to each record holder of
shares of Common Stock as of the close of business on the Distribution Date, at
the address of such holder shown on the records of the Company, a Rights
Certificate, in substantially the form of Exhibit B hereto (a "Rights
Certificate"), evidencing one Right for each share of Common Stock so held,
subject to adjustment as provided herein. In the event that an adjustment in the
number of Rights per share of Common Stock has been made pursuant to Section
11(h), at the time the Rights Certificates are distributed the Company shall
make the necessary and appropriate rounding adjustments pursuant to Section
14(a) so that Rights Certificates are distributed representing only whole
numbers of Rights and cash is paid in lieu of fractional Rights. As of and after
the Distribution Date, the Rights will be evidenced solely by such Rights
Certificates.

          (b) As soon as practicable following the Record Date, the Company will
send a copy of a Summary of Rights to Purchase Preferred Stock, in substantially
the form of Exhibit C (the "Summary of Rights"), by first-class, postage-prepaid
mail, to each record holder of shares of Common Stock as of the close of
business on the Record Date, at the address of such holder shown on the records
of the Company.

          (c) All Common Stock certificates which are issued, either upon an
original issuance by the Company or upon a transfer by a holder, after the
Record Date but prior to the earliest of the Distribution Date, the Redemption
Date or the Final Expiration Date, shall have impressed on, printed on, written
on or otherwise affixed to them the following legend:

                                       6
<PAGE>
          This certificate also evidences and entitles the holder hereof to
          certain rights set forth in a Rights Agreement between Sequent
          Computer Systems, Inc. (the "Company") and ChaseMellon Shareholder
          Services L.L.C. dated as of April 14, 1998 (the "Rights Agreement"),
          the terms of which are 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 will no
          longer be evidenced by this certificate. The Company will mail to the
          holder of this certificate a copy of the Rights Agreement without
          charge after receipt of a written request therefor. Under certain
          circumstances, Rights beneficially owned by Acquiring Persons or their
          Affiliates or Associates (as such terms are defined in the Rights
          Agreement), and Rights previously owned by such Persons, may become
          null and void.

     4.   Form of Rights Certificates.

          (a) The Rights Certificates (and the form of election to purchase and
form of assignment to be printed on the reverse thereof) shall be substantially
the same as Exhibit B hereto and may have such marks of identification or
designation and such legends, summaries or endorsements printed thereon as the
Company may deem appropriate and as are not inconsistent with the provisions of
this Agreement, or as may be required to comply with any applicable law or with
any rule or regulation made pursuant thereto or with any rule or regulation of
any stock exchange on which the Rights may from time to time be listed, or to
conform to usage. Subject to the provisions of Section 11 and Section 22, the
Rights Certificates, whenever distributed, shall entitle the holders thereof to
purchase for the Purchase Price such number of one one-hundredths of a share of
Preferred Stock as shall be set forth therein, but the amount and type of
securities purchasable upon exercise and the Purchase Price shall be subject to
adjustment as provided herein.

          (b) Any Rights Certificate issued pursuant to Section 3 hereof that
represents Rights beneficially owned by (i) an Acquiring Person or any Associate
or Affiliate of an Acquiring Person, (ii) any other Person if such Rights
formerly were beneficially owned by an Acquiring Person (or by an Associate or
Affiliate of such Acquiring Person) at a time after the Acquiring Person became
an Acquiring Person, or (iii) a transferee of Rights from an Acquiring Person
(or from any Associate or Affiliate thereof) who became a transferee prior to or
concurrently with the Acquiring Person becoming an Acquiring Person and receives
such Rights pursuant to either (A) a transfer (whether or not for consideration)
from the Acquiring Person (or its Affiliate or Associate) to holders of equity
interests in such Acquiring Person (or its Affiliate or Associate) or to any
Person with whom such Acquiring Person (or its Affiliate or Associate) has any
continuing agreement, arrangement or understanding regarding the transferred
Rights, or (B) a transfer which the Board of

                                       7
<PAGE>
Directors has determined is part of a plan, arrangement or understanding that
has as a primary purpose or effect the avoidance of Section 7(e), and any Rights
Certificate issued pursuant to Section 6, 7(d) or 22 upon transfer, exchange,
replacement or adjustment of any other Rights Certificate referred to in this
sentence, shall contain the following legend:

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

provided, however, that the Rights Agent shall not have any responsibility to
ascertain the existence of facts that would require the imposition of such
legend but shall be required to impose such legend only if instructed to do so
by the Company or if a holder fails to certify upon transfer or exchange in the
space provided on the Rights Certificate that such holder is not an Acquiring
Person or an Affiliate or Associate of an Acquiring Person.

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

     Following the Distribution Date, the Rights Agent will keep or cause to be
kept, at its principal offices, 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.

                                       8

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

          (a) Subject to the provisions of Sections 4(b), 7(e) and 14, at any
time after the close of business on the Distribution Date, and at or prior to
the close of business on the earlier of the Redemption Date or the Final
Expiration Date, any Rights Certificate or Certificates may be transferred,
split up, combined or exchanged for another Rights Certificate or Certificates,
entitling the registered holder to purchase a like number of shares of Preferred
Stock or other securities or property as the Rights Certificate or Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Rights Certificate or
Certificates shall make such request in writing delivered to the Rights Agent
and shall surrender the Rights Certificate or Certificates to be transferred,
split up, combined or exchanged at the office of the Rights Agent designated for
such purpose. Neither the Rights Agent nor the Company shall be obligated to
take any action whatsoever with respect to the transfer of any such surrendered
Rights Certificate until the registered holder shall have completed and signed
the certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) or Affiliates or
Associates thereof as the Company shall reasonably request. Thereupon the Rights
Agent shall, subject to Sections 4(b), 7(e) and 14, countersign and deliver to
the person entitled thereto a Rights Certificate or Rights Certificates, as the
case may be, as so requested. The Company may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split-up, combination or exchange of Rights
Certificates.

          (b) Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Rights Certificate, and, in case of loss, theft or destruction, of indemnity
or security reasonably satisfactory to them, and, at the Company's request,
reimbursement to the Company and the Rights Agent of all reasonable expenses
incidental thereto, and upon surrender to the Rights Agent and cancellation of
the Rights Certificate if mutilated, the Company will make and deliver a new
Rights Certificate of like tenor to the Rights Agent for delivery to the
registered holder in lieu of the Rights Certificate so lost, stolen, destroyed
or mutilated.

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

          (a) At any time after the Distribution Date and at or prior to the
earlier of (i) the close of business on April 14, 2008 (the "Final Expiration
Date") or (ii) the time at which the Rights are redeemed as provided in Section
23 (the "Redemption Date"), subject to Section 7(e), the registered holder of
any Rights Certificate may exercise the Rights evidenced thereby (except as
otherwise provided herein including, without limitation, the restrictions on
exercisability set forth in Sections 9(c), 11(a)(iii)) and 23(a) in whole or in
part upon surrender of the Rights Certificate, with the form of election to
purchase and certificate on the reverse side thereof duly executed, to the
Rights Agent at the office of the

                                       9
<PAGE>
Rights Agent designated for such purpose, together with payment of the Purchase
Price for each Right that is exercised.

          (b) The Purchase Price to be paid on exercise of each Right shall
initially be $130.00 and shall be payable in lawful money of the United States
of America in accordance with paragraph (c) below. Each Right shall initially
entitle the holder to acquire one one-hundredth of a share of Preferred Stock
upon exercise of the Right. The Purchase Price and the number of shares of
Preferred Stock or other securities or assets for which a Right is exercisable
shall be subject to adjustment as provided in Sections 11 and 13.

          (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase duly executed, accompanied by
payment of the Purchase Price for the shares to be purchased and an amount equal
to any applicable transfer tax in cash, or by certified check or cashier's check
payable to the order of the Company, the Rights Agent shall, subject to Section
20(k), thereupon promptly (i) requisition from any transfer agent of the
Preferred Stock (or make available, if the Rights Agent is the transfer agent)
certificates for the number of shares of Preferred Stock to be purchased and the
Company hereby authorizes its transfer agent to comply with all such requests,
(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,
(iii) after receipt of the certificates for Preferred Stock 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, deliver such cash to or upon
the order of the registered holder of such Rights Certificate. In the event that
the Company is obligated to issue other securities (including, but not limited
to, debt securities) of the Company, and/or distribute other property pursuant
to Section 11, the Company covenants that it will make all arrangements
necessary so that such other securities and/or property are available for
distribution by the Rights Agent, if and when appropriate.

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

          (e) Notwithstanding any other provision of this Agreement, from and
after the occurrence of a Stock Acquisition Date, any Rights beneficially owned
by (i) an Acquiring Person, or any Associate or Affiliate of an Acquiring
Person, (ii) any other Person if such Rights formerly were beneficially owned by
an Acquiring Person (or by an Associate or Affiliate of such Acquiring Person)
at a time after such Acquiring Person became an Acquiring Person, or (iii) a
transferee of Rights from an Acquiring Person (or from any Associate or
Affiliate thereof) who became a transferee prior to or concurrently with the
Acquiring Person becoming an Acquiring Person and receives such Rights pursuant
to either (A) a transfer (whether or not for consideration) from the Acquiring
Person (or its Affiliate

                                       10
<PAGE>
or Associate) to holders of equity interests in such Acquiring Person (or its
Affiliate or Associate) or to any Person with whom the Acquiring Person (or its
Affiliate or Associate) has any continuing agreement, arrangement or
understanding regarding the transferred Rights, or (B) a transfer which the
Board of Directors has determined is part of a plan, arrangement or
understanding that has as a primary purpose or effect the avoidance of this
Section 7(e), shall become null and void and any holder of such Rights shall
thereafter have no right to exercise such Rights under any provision of this
Agreement. The Company shall use all reasonable efforts to ensure that the
provisions of this Section 7(e) and of Section 4(b) are complied with, but shall
have no liability to any holder of Rights Certificates or any other Person as a
result of its failure to make any determinations with respect to an Acquiring
Person, or any of its Affiliates, Associates or transferees hereunder.

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

     8. Cancellation and Destruction of Rights Certificates. All Rights
Certificates surrendered for the purpose of exercise, transfer, split-up,
combination or exchange shall, if surrendered to the Company or to any of its
agents, be delivered to the Rights Agent for cancellation or in cancelled form,
or, if surrendered to the Rights Agent, shall be cancelled by it, and no Rights
Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Agreement. The Company shall deliver to the Rights
Agent for cancellation and retirement, and the Rights Agent shall so cancel and
retire, any other Rights Certificate purchased or acquired by the Company
otherwise than upon the exercise thereof. The Rights Agent shall deliver all
cancelled Rights Certificates to the Company, or shall, at the written request
of the Company, destroy such cancelled Rights Certificates, and in such case
shall deliver a certificate of destruction thereof to the Company.

     9.   Reservation and Availability of Capital Stock.

          (a) The Company covenants and agrees that it will cause to be reserved
and kept available out of its authorized and unissued Preferred Stock (and,
following the occurrence of a Stock Acquisition Date or a Section 13 Event, out
of its authorized and unissued shares of Common Stock and/or other securities),
the number of shares of Preferred Stock (and, following the occurrence of a
Stock Acquisition Date or a Section 13 Event, Common Stock and/or other
securities) that, as provided in this Agreement, will be sufficient to permit
the exercise in full of all outstanding Rights; provided, however, that shares
issuable pursuant to Section 11(a)(ii) shall be reserved only following the
occurrence of an event described in that section.

                                       11
<PAGE>
          (b) If any shares of Preferred Stock are listed on a national
securities exchange, and so long as the shares of Preferred Stock (and,
following the occurrence of a Stock Acquisition Date or a Section 13 Event,
Common Stock and/or other securities) issuable and deliverable upon the exercise
of the Rights may be listed on that exchange, the Company shall use its best
efforts to cause, from and after such time as the Rights become exercisable, all
shares reserved for such issuance to be listed on the exchange upon official
notice of issuance upon exercise.

          (c) The Company shall use its best efforts (i) to file, as soon as
practicable following a Stock Acquisition Date and the determination by the
Company in accordance with Section 11(a)(iii) of the consideration to be
delivered by the Company upon exercise of the Rights, or as soon as is required
by law following the Distribution Date, as the case may be, a registration
statement under the Act with respect to the securities purchasable upon exercise
of the Rights on an appropriate form, (ii) to cause such registration statement
to become effective as soon as practicable after such filing, and (iii) to cause
such registration statement to remain effective (with a prospectus at all times
meeting the requirements of the Act) until the earlier of (A) the date as of
which the Rights are no longer exercisable for such securities, and (B) the date
of the expiration of the Rights. The Company will also take such action as may
be appropriate under or to ensure compliance with, the securities or "blue sky"
laws of the various states in connection with the exercisability of the Rights.
The Company may temporarily suspend the exercisability of the Rights, for a
period of time not to exceed 90 days after the date the Company first becomes
obligated to use its best efforts to file a registration statement as set forth
in clause (i) of the first sentence of this Section 9(c), in order to prepare
and file such registration statement and permit it to become effective. Upon any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect.
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 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 shares of Preferred Stock (and, following
the occurrence of a Stock Acquisition Date or Section 13 Event, Common Stock
and/or other securities) delivered upon exercise of Rights shall, at the time of
delivery of the certificates for such shares of such shares (subject to payment
of the Purchase Price), be duly and validly authorized and issued and fully paid
and nonassessable shares.

          (e) The Company further covenants and agrees that it will pay when due
and payable any and all federal and state transfer taxes and charges which may
be payable in respect of the issuance or delivery of the Rights Certificates or
of any shares of Preferred Stock or other securities upon the exercise of
Rights. The Company shall not, however, be required to pay any transfer tax
which may be payable in respect of any transfer, split-up, combination or
exchange of Rights Certificates, or any issuance or delivery of certificates for

                                       12
<PAGE>
shares in a name other than that of the registered holder of the Rights
Certificate evidencing Rights surrendered for exercise, and shall not be
required to issue or deliver any certificates for shares upon the exercise of
any Rights until any such tax shall have been paid (any such tax being payable
by the holder of such Rights Certificate at the time of surrender) or until it
has been established to the Company's satisfaction that no such tax is due.

     10. Preferred Stock Record Date. Each person in whose name any certificate
for a number of one one-hundredths of a share of Preferred Stock (or Common
Stock and/or other securities, as the case may be) is issued upon the exercise
of Rights shall for all purposes be deemed to have become the holder of record
of such fractional shares of Preferred Stock (or Common Stock and/or other
securities, as the case may be) represented thereby on, and such certificate
shall be dated, the date upon which the Rights Certificate evidencing such
Rights was duly surrendered and payment of the Purchase Price (and any
applicable transfer taxes) was made; provided, however, that if the date of such
surrender and payment is a date upon which the Preferred Stock (or Common Stock
and/or other securities, as the case may be) transfer books of the Company are
closed, such person shall be deemed to have become the record holder of such
shares (fractional or otherwise) on, and such certificate shall be dated, the
next succeeding Business Day on which the Preferred. Stock (or Common Stock
and/or other securities, as the case may be) transfer books of the Company are
open. Prior to the exercise of the Rights evidenced thereby, the holder of a
Rights Certificate shall not be entitled to any rights of a shareholder of the
Company with respect to shares for which the Rights shall be exercisable,
including, without limitation, 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.

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

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

                                       13
<PAGE>
     reclassification. The adjustments provided for in this Section 11(a)(i)
     shall be made successively whenever such a dividend is declared or paid or
     such a subdivision, combination or reclassification is effected. If an
     event occurs which would require an adjustment under both this Section
     11(a)(i) and Section 11(a)(ii), the adjustment provided for in this Section
     11(a)(i) shall be in addition to, and shall be made prior to, any
     adjustment required pursuant to Section 11(a)(ii).

               (ii) In the event that a Stock Acquisition Date occurs, proper
     provision shall be made so that each holder of a Right, except as provided
     below and in Section 7(e), shall thereafter have a right to receive, upon
     exercise thereof and payment of the Purchase Price in accordance with the
     terms of this Agreement, in lieu of a number of one one-hundredths of a
     share of Preferred Stock, such number of shares of Common Stock as shall
     equal the result obtained by dividing the then current Purchase Price by 50
     percent of the Current Per Share Market Price of the Common Stock
     (determined pursuant to Section 11(d)) on the Stock Acquisition Date (such
     number of shares being the "Adjustment Shares").

               (iii) In the event the number of shares of Common Stock which are
     authorized by the Company's articles of incorporation but not outstanding
     or reserved for issuance for purposes other than upon exercise of the
     Rights are not sufficient to permit the exercise in full of the Rights in
     accordance with the foregoing subparagraph (ii) of this Section 11(a), the
     Company shall (A) determine the excess of (1) the value of the Adjustment
     Shares issuable upon the exercise of a Right (the "Current Value") over (2)
     the then current Purchase Price (such excess, the "Spread"), and (B) with
     respect to each Right, make adequate provision to substitute for the
     Adjustment Shares, upon payment of the applicable Purchase Price, (1) cash,
     (2) a reduction in the applicable Purchase Price, (3) shares of Common
     Stock or other equity securities of the Company (including, without
     limitation, shares, or units of shares, of preferred stock that the Board
     of Directors of the Company has deemed to have the same value as shares of
     Common Stock ("Common Stock Equivalents")), (4) debt securities of the
     Company, (5) other assets, or (6) any combination of the foregoing, having
     an aggregate value equal to the Current Value, where such aggregate value
     has been determined by the Board of Directors of the Company based upon the
     advice of a nationally recognized investment banking firm selected by the
     Board of Directors of the Company; provided, however, if the Company shall
     not have made adequate provision to deliver value pursuant to clause (B)
     above within 30 days following the Stock Acquisition Date, then the Company
     shall be obligated to deliver, upon the surrender for exercise of a Right
     and without requiring payment of the Purchase Price, shares of Common Stock
     (to the extent available) and then, if necessary, cash, which shares and/or
     cash have an aggregate value equal to the Spread. If the Board of Directors
     of the Company shall determine in good faith that it is likely that
     sufficient additional shares of Common Stock could be authorized for
     issuance upon exercise in full of the Rights, the 30-day period set forth
     above may be extended to the extent necessary, but not more than 90 days
     after the Stock

                                       14
<PAGE>
     Acquisition Date, in order that the Company may seek shareholders approval
     for the authorization of such additional shares (such period, as it may be
     extended as so permitted, the "Substitution Period"). To the extent the
     Company determines that some action must be taken pursuant to the first or
     second sentences of this Section 11(a)(iii), the Company (x) shall provide
     that such action shall apply uniformly to all outstanding Rights other than
     those that are void as provided in Section 7(e), and (y) may suspend the
     exercisability of the Rights until the expiration of the Substitution
     Period in order to seek any authorization of additional shares and/or to
     decide the appropriate form of distribution to be made pursuant to such
     first sentence and to determine the value thereof. In the event of any such
     suspension, the Company shall issue a public announcement stating that the
     exercisability of the Rights has been temporarily suspended, as well as a
     public announcement at such time as the suspension is no longer in effect.
     For purposes of this Section 11(a)(iii), the value of the Common Stock
     shall be the Current Per Share Market Price (as determined pursuant to
     Section 11(d) hereof) of the Common Stock on the date of the Stock
     Acquisition Date and the value of any Common Stock Equivalent shall be
     deemed to have the same value as the Common Stock 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 Stock entitling them (for a period expiring within 45
calendar days after such record date) to subscribe for or purchase Preferred
Stock (or shares having the same rights, privileges and preferences as the
Preferred Stock ("Preferred Stock Equivalents")) or securities convertible into
Preferred Stock or Preferred Stock Equivalents at a price per share of Preferred
Stock or Preferred Stock Equivalent (or having a conversion price per share, if
a security convertible into Preferred Stock or Preferred Stock Equivalents) less
than the then Current Per Share Market Price of the Preferred Stock (as defined
in Section 11(d)) on such record date, the number of shares of Preferred Stock
for which each Right shall be exercisable after such record date shall
determined by multiplying the number of shares of Preferred Stock for which each
Right was exercisable immediately prior to such record date by a fraction, the
numerator of which shall be the number of shares of Preferred Stock outstanding
on such record date plus the number of additional shares of Preferred Stock
and/or Preferred Stock Equivalents to be offered for subscription or purchase
(or into which the convertible securities so to be offered are initially
convertible) and the denominator of which shall be the number of shares of
Preferred Stock outstanding on such record date plus the number of shares of
Preferred Stock which the aggregate offering price of the total number of shares
of Preferred Stock and/or Preferred Stock Equivalents so to be offered (and/or
the aggregate initial conversion price of convertible securities so to be
offered) would purchase at such Current Per Share Market Price. In case such
subscription price may be paid in a consideration part or all of which shall be
in a form other than cash, the value of such consideration shall be as
determined in good faith by the Board of Directors, whose determination shall be
described in a statement filed with the Rights Agent. Preferred Stock owned by
or held for the account of the Company shall not be deemed outstanding for the
purpose of any such computation. Such adjustment shall be made successively
whenever

                                       15
<PAGE>
such a record date is fixed; and in the event that such rights, options or
warrants are not so issued, the number of shares of Preferred Stock for which
each Right shall be exercisable shall be readjusted to be the number of shares
of Preferred Stock for which each Right would then be exercisable if such record
date had not been fixed; and to the extent such rights, options or warrants are
issued but not exercised prior to their expiration, the number of shares for
which each Right shall be exercisable shall be readjusted to be the number which
would have resulted from the adjustment provided for in this Section 11(b) if
only the rights or warrants that were exercised had been issued.

          (c) (i) 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 Preferred Stock (including any such distribution made in connection with
     a consolidation or merger in which the Company is the continuing or
     surviving corporation) of evidences of indebtedness or assets (other than a
     regular quarterly cash dividend or a dividend payable in shares of
     Preferred Stock but including any dividend payable in stock other than
     Preferred Stock) or subscription rights or warrants (excluding those
     referred to in Section 11(b)), the number of shares of Preferred Stock for
     which each Right shall be exercisable after such record date shall be
     determined by multiplying the number of shares of Preferred Stock for which
     each Right was exercisable immediately prior to such record date by a
     fraction, the numerator of which shall be the then Current Per Share Market
     Price of the Preferred Stock (as defined in Section 11(d)) on such record
     date, and the denominator of which shall be such Current Per Share Market
     Price of the Preferred Stock, less the fair market value (as determined in
     good faith by the Board of Directors, whose determination shall be
     described in a statement filed with the Rights Agent) of the portion of the
     assets or evidences of indebtedness so to be distributed or of such
     subscription rights or warrants applicable to one share of Preferred Stock.
     Such adjustments shall be made successively whenever such a record date is
     fixed; and in the event that such distribution is not so made, the number
     of shares of Preferred Stock for which each Right shall be exercisable
     shall be readjusted to be the number of shares of Preferred Stock for which
     each Right would then be exercisable if such record date had not been
     fixed.

               (ii) 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 Common Stock (including any such distribution made in connection with a
     consolidation or merger in which the Company is the continuing or surviving
     corporation) of evidences of indebtedness or assets (other than a regular
     quarterly cash dividend or a dividend payable in shares of Common Stock) or
     subscription rights or warrants (excluding those referred to in Section
     11(h)(ii)), the number of shares of Preferred Stock for which each Right
     shall be exercisable after such record date shall be determined by
     multiplying the number of shares of Preferred Stock for which each Right
     was exercisable immediately prior to such record date by a fraction, the
     numerator of which shall be the then Current Per Share Market Price of the

                                       16
<PAGE>
     Common Stock (as defined in Section 11(d)) on such record date, and the
     denominator of which shall be such Current Per Share Market Price of the
     Common Stock, less the fair market value (as determined in good faith by
     the Board of Directors, whose determination shall be described in a
     statement filed with the Rights Agent) of the portion of the assets or
     evidences of indebtedness so to be distributed or of such subscription
     rights or warrants applicable to one share of Common Stock. Such
     adjustments shall be made successively whenever such a record date is
     fixed; and in the event that such distribution is not so made, the number
     of shares of Preferred Stock for which each Right shall be exercisable
     shall be readjusted to be the number of shares of Preferred Stock for which
     each Right would then be exercisable if such record date had not been
     fixed.

          (d) (i) For the purpose of any computation hereunder, the "Current Per
     Share Market Price" of common stock (including Common Stock) on any date
     shall be deemed to be the average of the daily closing prices per share of
     the common stock for the 30 consecutive Trading Days (as such term is
     hereinafter defined) immediately prior to such date; provided, however,
     that in the event the Current Per Share Market Price of common stock is
     determined during a period following the announcement by the issuer of such
     common stock of (A) a dividend or distribution on such common stock payable
     in such common stock or securities convertible into such common stock, or
     (B) any subdivision, combination or reclassification of such common stock,
     and prior to the expiration of 30 Trading Days after the ex-dividend date
     for such dividend or distribution, or the record date for such subdivision,
     combination or reclassification, then, and in each such case, the Current
     Per Share Market Price shall be appropriately adjusted to take into account
     such event. The closing price for each day shall be the last sale price,
     or, in case no such sale takes place on such day, the average of the high
     bid and low asked prices in the over-the-counter market, as reported by the
     National Market System of the National Association of Securities Dealers,
     Inc. Automated Quotations system ("NASDAQ") or such other system then in
     use, or, if on any such date the common stock is not quoted by any such
     organization, the average of the closing bid and asked prices as furnished
     by a professional market maker making a market in the common stock selected
     by a majority of the Board of Directors. The term "Trading Day" shall mean
     a day on which the principal national securities exchange on which the
     common stock is listed or admitted to trading is open for the transaction
     of business or, if the common stock is not listed or admitted to trading on
     any national securities exchange, a Business Day. If the common stock 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 described
     in a statement filed with the Rights Agent.

               (ii) For the purpose of any computation hereunder, the "Current
     Per Share Market Price" of Preferred Stock shall be determined in the same
     manner as set forth above for the Common Stock in clause (i) of this
     Section 11(d) (other than the

                                       17
<PAGE>
     last sentence thereof). If the Current Per Share Market Price of Preferred
     Stock cannot be determined in the manner provided above or if the Preferred
     Stock is not publicly held or listed or traded in a manner described in
     clause (i) of this Section 11(d), the "Current Per Share Market Price" of
     Preferred Stock shall be conclusively deemed to be an amount equal to the
     Current Per Share Market Price of the Common Stock multiplied by the
     Adjustment Number as that term is defined in Section 2 of the Amendment to
     the Company's Articles of Incorporation, as amended, designating the
     Preferred Stock (initially 100). If neither the Common Stock nor the
     Preferred Stock is publicly held or so listed or traded, "Current Per Share
     Market Price" of Preferred Stock shall mean the fair value per share as
     determined in good faith by the Board of Directors of the Company, whose
     determination shall be described in a statement filed with the Rights Agent
     and shall be conclusive for all purposes. For all purposes of this
     Agreement, the current market price of one one-hundredth of a share of
     Preferred Stock shall be equal to the Current Per Share Market Price of one
     share of Preferred Stock divided by 100.

          (e) No adjustment in the Purchase Price or the number of shares for
which a Right is exercisable shall be required unless such adjustment would
require an increase or decrease of at least one percent in the Purchase Price or
the number of shares for which a Right is exercisable; provided, however, that
any adjustments which by reason of this Section 11(e) are not required to be
made shall be carried forward and taken into account in any subsequent
adjustment. All calculations under this Section 11 shall be made to the nearest
cent or to the nearest ten-thousandth of a share of Common Stock or
one-millionth of a share of Preferred Stock, as the case may be. Notwithstanding
the first sentence of this Section 11(e), any adjustment required by this
Section 11 shall be made no later than the earlier of (i) three years from the
date of the transaction which requires such adjustment or (ii) the date of the
expiration of the right to exercise any Rights.

          (f) If as a result of an adjustment made pursuant to Section 11(a),
the holder of any Right thereafter exercised shall become entitled to receive
any shares of capital stock of the Company other than Preferred Stock,
thereafter the number of such other shares so receivable upon exercise of any
Right shall be subject to adjustment from time to time in a manner and on terms
as nearly equivalent as practicable to the provisions with respect to the
Preferred Stock contained in Section 11 and the provisions of Sections 7, 9, 10,
13 and 14 with respect to the Preferred Stock shall apply on like terms to any
such other shares.

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

                                       18

          (h) (i) In the event the Company shall, after the date of this
     Agreement and prior to the Distribution Date, (A) declare a dividend on the
     Common Stock payable in Common Stock, (B) subdivide the outstanding Common
     Stock, (C) combine the outstanding Common Stock into a smaller number of
     shares of Common Stock, or (D) issue any shares of Common Stock in a
     reclassification of the Common Stock (including any such reclassification
     in connection with a consolidation or merger in which the Company is the
     continuing or surviving corporation), the number of Rights associated with
     each share of Common Stock then outstanding, and the number of Rights to be
     associated with each share of Common Stock which may thereafter become
     outstanding prior to the Distribution Date, shall be proportionately
     adjusted so that the number of Rights associated with each share of Common
     Stock following any such event shall equal the result obtained by
     multiplying the number of Rights associated with each share of Common Stock
     immediately prior to such event by a fraction, the numerator of which shall
     be the number of shares of Common Stock outstanding immediately prior to
     such event and the denominator of which shall be the number of shares of
     Common Stock outstanding immediately after such event.

               (ii) In the event the Company shall, after the date of this
     Agreement and prior to the Distribution Date, fix a record date for the
     issuance of rights, options or warrants to all holders of Common Stock
     entitling them (for a period expiring within 45 calendar days after such
     record date) to subscribe for or purchase Common Stock or securities
     convertible into Common Stock at a price per share of Common Stock (or
     having a conversion price per share, if a security convertible into Common
     Stock) less than the then Current Per Share Market Price of the Common
     Stock (as defined in Section 11(d)) on such record date, the number of
     Rights associated with each share of Common Stock then outstanding, and the
     number of Rights to be associated with each share of Common Stock which may
     thereafter become outstanding prior to the Distribution Date, shall be
     proportionately adjusted so that the number of Rights associated with each
     share of Common Stock after such record date shall be determined by
     multiplying the number of Rights associated with each share of Common Stock
     immediately prior to such record date by a fraction, the numerator of which
     shall be the number of shares of Common Stock outstanding on such record
     date plus the number of shares of Common Stock which the aggregate offering
     price of the total number of shares of Common Stock so to be offered
     (and/or the aggregate initial conversion price of the convertible
     securities so to be offered) would purchase at such Current Per Share
     Market Price and the denominator of which shall be the number of shares of
     Common Stock outstanding on such record date plus the number of additional
     shares of Common Stock to be offered for subscription or purchase (or into
     which the convertible securities so to be offered are initially
     convertible). In case such subscription price may be paid in a
     consideration part or all of which shall be in a form other than cash, the
     value of such consideration shall be as determined in good faith by the
     Board of Directors, whose determination shall be described in a statement
     filed with the Rights Agent. Common Stock owned by or held for the account
     of the Company shall not be deemed outstanding for the purpose of any such
     computation.

                                       19
<PAGE>
     Such adjustment shall be made successively whenever such a record date is
     fixed. In the event that such rights, options or warrants are not so
     issued, the number of Rights associated with each share of Common Stock
     shall be readjusted to be the number of Rights that would have been
     associated with each share of Common Stock if such record date had not been
     fixed; and to the extent such rights, options or warrants are issued but
     not exercised prior to their expiration, the number of Rights associated
     with each share shall be readjusted to be the number which would have
     resulted from the adjustment provided for in this Section 11(h)(ii) if only
     the rights, options or warrants that were exercised had been issued.

               (iii) Notwithstanding the foregoing, the adjustments provided for
     in this Section 11(h) shall not be made if the Company exercises its
     election provided for in Section 11(i).

          (i) The Company may elect on or after the date of any event described
in clauses (A) through (D) of Section 11(h)(i) or described in Section
11(h)(ii), if such event occurs before the Distribution Date (a "Section 11(h)
Event"), to adjust the Purchase Price and the number of shares of Preferred
Stock purchasable upon the exercise of a Right in substitution for any
adjustment under Section 11(h) in the number of Rights associated with each
share of Common Stock. If such election is made, (i) the number of Rights
associated with each share of Common Stock prior to the Section 11(h) Event
shall be maintained after the Section 11(h) Event, (ii) any new shares of Common
Stock issued in the Section 11(h) Event shall, as provided in Section 3(a), have
issued with it the number of Rights associated with each share of Common Stock
outstanding, and (iii) any combination of shares of Common Stock into a smaller
number of shares in the Section 11(h) Event shall result in a similar
combination of the associated Rights. The Purchase Price and the number of
Shares of Preferred Stock purchasable upon exercise of a Right after such
adjustment shall be determined by multiplying the Purchase Price and the number
of Shares of Preferred Stock purchasable upon exercise of a Right, respectively,
in effect immediately prior to such adjustment by a fraction, the numerator of
which shall be the number of Rights that would have been associated with each
share of Common Stock after the Section 11(h) Event if the Company had not
exercised its election provided for in this Section 11(i) and the denominator of
which shall be the number of Rights associated with each share of Common Stock
immediately prior to the Section 11(h) Event. To the extent the number of Rights
that would have been associated with each share of Common Stock if the Company
had not exercised its election provided for in this Section 11(i) may be
readjusted as provided in the last sentence of Section 11(h)(ii), the Purchase
Price and number of shares of Preferred Stock purchasable upon exercise of a
Right shall be similarly readjusted.

          (j) Irrespective of any adjustment or change in the Purchase Price or
the number of one one-hundredths of a share of Preferred Stock issuable upon the
exercise of the Rights, the Rights Certificates theretofore and thereafter
issued may continue to express the Purchase Price per one one-hundredth of a
share and the number of one one-hundredths of a

                                       20
<PAGE>
share of Preferred Stock which were expressed in the initial Rights Certificates
issued hereunder.

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

          (l) Anything in this Section 11 to the contrary notwithstanding, the
Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that in their good faith judgment the Board of Directors shall
determine to be advisable in order that any consolidation or subdivision of the
Preferred Stock, issuance wholly for cash of any Preferred Stock at less than
the current market price, issuance wholly for cash of Preferred Stock or
securities which by their terms are convertible into or exchangeable for shares
of Preferred Stock, dividends on Preferred Stock payable in Preferred Stock or
issuance of rights, options or warrants referred to in Section 11(b), hereafter
made by the Company to holders of its Preferred Stock shall not be taxable to
such shareholders or shall reduce the taxes payable by such shareholders.

          (m) The Company covenants and agrees that, after the Distribution
Date, it will not, except as permitted by Section 23 or Section 26, take (or
permit any Subsidiary to take) any action, including any merger, consolidation
or sale of assets if at the time such action is taken or immediately thereafter
it is reasonably foreseeable that such action will diminish substantially or
otherwise eliminate the benefits intended to be afforded by the Rights.

     12. Certificate of Adjusted Purchase Price or Number of Shares. Whenever an
adjustment is made as provided in Sections 11 and 13, the Company shall promptly
(a) prepare a certificate setting forth such adjustment and a brief statement of
the facts accounting for such adjustment, (b) file with the Rights Agent and
with each transfer agent for the Preferred Stock and the Common Stock a copy of
such certificate and (c) mail a brief summary thereof to each holder of Rights
in accordance with Section 25.

                                       21
<PAGE>
     13. Consolidation, Merger or Sale or Transfer of Assets or Earning Power.

          (a) In the event that, following the Distribution Date, directly or
     indirectly,

               (i) the Company shall consolidate with, or merge with and into,
     any other Person (other than a Subsidiary of the Company in a transaction
     that complies with Section 11(m)) and the Company shall not be the
     continuing or surviving corporation of such consolidation or merger,

               (ii) any Person shall acquire shares of Common Stock of the
     Company in a share exchange,

               (iii) any Person (other than a Subsidiary of the Company in a
     transaction that complies with Section 11(m)) shall consolidate with the
     Company, or merge with and into the Company and the Company shall be the
     continuing or surviving corporation of such consolidation or merger and, in
     connection with such consolidation or merger, all or part of the
     outstanding Common Stock shall be changed into or exchanged for stock or
     other securities of any other Person or cash or any other property, or

               (iv) 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 percent or more of the
     assets or earning power of the Company and its Subsidiaries (taken as a
     whole) to any Person other than the Company or one or more of its wholly
     owned Subsidiaries in a transaction that complies with Section 11(m),

then, and in each such case, proper provision shall be made so that (A) each
holder of a Right (except as otherwise provided in Section 7(e)) shall
thereafter have the right to receive, upon the exercise thereof and payment of
the Purchase Price in accordance with the terms of this Agreement, such number
of validly authorized and issued, fully paid, nonassessable and freely tradeable
shares of common stock of the Principal Party (as hereinafter defined) not
subject to any liens, encumbrances, rights of first refusal or other adverse
claims, as shall be equal to the result obtained by dividing the then current
Purchase Price by 50 percent of the Current Per Share Market Price of the common
stock of the Principal Party (determined pursuant to Section 11(d)) on the date
of consummation of the Section 13 Event, (B) the 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 the Principal Party,
it being specifically intended that the provisions of Section 11 shall apply to
the Principal Party only following the first occurrence of a Section 13 Event,
and (D) the Principal Party shall take such steps (including, but not limited
to, the reservation of a sufficient number of shares of its common stock in
accordance with Section 9) in connection with such consummation as may be
necessary to ensure that the provisions of this Agreement shall thereafter be

                                       22
<PAGE>
applicable, as nearly as reasonably may be, in relation to the common stock
thereafter deliverable upon the exercise of the Rights. The provisions of
Section 11(a)(ii) shall be of no effect following the first occurrence of an
event described in Section 13.

          (b) The term "Principal Party" shall mean

               (i) in the case of any transaction described in clause (i), (ii)
     or (iii) of Section 13(a), the Person that is the issuer of any securities
     into which shares of Common Stock of the Company are converted in such
     merger or consolidation, or for which shares of Common Stock are exchanged
     in such share exchange, and if no securities are so issued, the Person that
     is the other party to such merger, consolidation or share exchange or, if
     there is more than one such Person, the Person the common stock of which
     has the highest aggregate current market price (determined pursuant to
     Section 11(d)); and

               (ii) in the case of any transaction described in clause (iv) of
     Section 13(a), the Person that is the party receiving the greatest portion
     of the assets or earning power transferred pursuant to such transaction or
     transactions; or, if each Person that is a party to such transaction or
     transactions receives the same portion of the assets or earning power
     transferred pursuant to such transaction or transactions or if the Person
     receiving the largest portion of the assets or earning power cannot be
     determined, whichever Person the common stock of which has the highest
     aggregate current market price (determined pursuant to Section 11(d));

provided, however, that, if the common stock of such Person is not at such time
and has not been continuously over the preceding 12-month period registered
under Section 12 of the Exchange Act or such Person is not a corporation, then
(A) if such Person is a direct or indirect Subsidiary of one other Person which
has common stock so registered, "Principal Party" shall refer to such other
Person, (B) if such Person is a direct or indirect Subsidiary of another Person
but is not a direct or indirect Subsidiary of another Person which has common
stock so registered, "Principal Party" shall refer to the ultimate parent entity
of such first-mentioned Person, (C) if such Person is directly or indirectly
controlled by more than one Person, and one or more of such other persons has
common stock so registered, "Principal Party" shall refer to whichever of such
Persons that is the issuer of common stock so registered having the highest
aggregate current market price (determined pursuant to Section 11(d)), and (D)
if such Person is directly or indirectly controlled by more than one Person, and
none of such other Persons have common stock so registered, "Principal Party"
shall refer to whichever ultimate parent entity is the corporation having the
greatest shareholders' equity or, if no such ultimate parent entity is a
corporation, shall refer to whichever ultimate parent entity is the entity
having the greatest net assets.

          (c) The Company shall not enter into any transaction described in this
Section 13 if at the time of such transaction there are any rights, warrants,
instruments or securities outstanding or any agreements or arrangements which,
as a result of the

                                       23
<PAGE>
consummation of such transaction, would eliminate or substantially diminish the
benefits intended to be afforded by the Rights. In addition, the Company shall
not consummate any such transaction unless the Principal Party shall have a
sufficient number of authorized shares of common stock which have not been
issued or reserved for issuance to permit the exercise in full of the Rights in
accordance with this Section 13 and unless prior thereto the Company and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing for the terms set forth in this Section 13 and
further providing that, as soon as practicable after execution of such
agreement, the Principal Party will

               (i) prepare and file a registration statement under the Act with
     respect to the securities purchasable upon exercise of the Rights on an
     appropriate form, and will use its best efforts to cause such registration
     statement to (A) become effective as soon as practicable after such filing,
     (B) remain effective (with a prospectus at all times meeting the
     requirements of the Act) until the Final Expiration Date and, as soon as
     practicable following the execution of such agreement, take such action as
     may be required to ensure that any acquisition of such shares of common
     stock upon the exercise of the Rights complies with any applicable state
     security or "blue sky" laws; and

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

          (d) In case the Principal Party which is to be a party to a
transaction referred to in this Section 13 has a provision in any of its
authorized securities or in its Articles or Certificate of Incorporation or
Bylaws or other instrument governing its corporate affairs, which provision
would have the effect of (i) causing such Principal Party to issue, in
connection with, or as a consequence of, the consummation of a transaction
referred to in this Section 13, shares of common stock of such Principal Party
at less than the then Current Per Share Market Price (determined pursuant to
Section 11(d)) or securities exercisable for, or convertible into, shares of
common stock of such Principal Party at less than the then Current Per Share
Market Price (other than to holders of Rights pursuant to this Section 13) or
(ii) providing for any special payment, tax or similar provisions in connection
with the issuance of the shares of common stock of such Principal Party pursuant
to the provisions of Section 13; then, in such event, the Company shall not
consummate any such transaction unless prior thereto the Company and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing that the provision in question of such
Principal Party shall have been cancelled, waived or amended, or that the
authorized securities shall be redeemed, so that the applicable provision will
have no effect in connection with, or as a consequence of, the consummation of
the proposed transaction.

          (e) The provisions of this Section 13 shall similarly apply to
successive mergers or consolidations or sales or other transfers. In the event
that a Section 13 Event

                                       24
<PAGE>
shall occur at any time after the Stock Acquisition Date, the Rights which have
not theretofore been exercised shall thereafter become exercisable in the manner
described in Section 13. The provisions of Section 11(a)(ii) shall be of no
effect following the first occurrence of a Section 13 Event.

     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 Right would otherwise
be issuable, an amount in cash equal to the same fraction of the current market
value of a whole Right. For the purposes of this Section 14(a), the current
market value of a whole Right shall be the closing price of the Rights for the
Trading Day immediately prior to the date on which such fractional Rights would
have been otherwise issuable. The closing price for any day shall be the last
sale price, or, in case no such sale takes place on such day, the average of the
high bid and low asked prices in the over-the-counter market, as reported by
NASDAQ or such other system then in use or, if on any such date the Rights are
not quoted by any such organization, the average of the closing bid and asked
prices as furnished by a professional market maker making a market in the Rights
selected by the Board of Directors of the Company. If on any such date no such
market maker is making a market in the Rights, the fair value of the Rights on
such date as determined in good faith by the Board of Directors of the Company
shall be used.

          (b) The Company shall not be required to issue fractions of shares of
Preferred Stock (other than fractions which are integral multiples of one
one-hundredth of a share of Preferred Stock) upon exercise of the Rights or to
distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one one-hundredth of a
share of Preferred Stock). In lieu of fractional shares of Preferred Stock that
are not integral multiples of one one-hundredths of a share of Preferred Stock
the Company shall pay to the registered holders of Rights Certificates at the
time such Rights are exercised as herein provided an amount in cash equal to the
same fraction of the current market value of one one-hundredth of a share of
Preferred Stock. For purposes of this Section 14(b), the current market value of
one one-hundredth of a share of Preferred Stock shall be one one-hundredth of
the closing price of a share of Preferred Stock (as determined pursuant to
Section 11(d)(ii) hereof) for the Trading Day immediately prior to the date of
such exercise.

          (c) Following the occurrence of a Stock Acquisition Date or Section 13
Event, the Company shall not be required to issue fractions of shares of Common
Stock upon exercise of the Rights or to distribute certificates which evidence
fractional shares of Common Stock. In lieu of fractional shares of Common Stock,
the Company may pay to the registered holders of Rights Certificates at the time
such Rights are exercised as herein provided an amount in cash equal to the same
fraction of current market value of one share

                                       25
<PAGE>
of Common Stock. For purposes of this Section 14(c), the current market value of
one share of Common Stock shall be the closing price of one share of Common
Stock (as determined pursuant to Section 11(d)(i) hereof) for the Trading Day
immediately prior to the date of such exercise.

          (d) The holder of a Right by the acceptance of the Right expressly
waives his right to receive any fractional Rights or any fractional shares upon
exercise of a Right (except as provided above).

     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, are
vested in the respective registered holders of the Rights Certificates (and,
prior to the Distribution Date, the registered holders of the Common Stock); and
any registered holder of any Right Certificate (or, prior to the Distribution
Date, of Common Stock), without the consent of the Rights Agent or of the holder
of any other Right Certificate (or, prior to the Distribution Date, of Common
Stock), may, in his own behalf and for his 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 right to exercise the Rights
evidenced by such Rights Certificate in the manner provided in such Rights
Certificate and in this Agreement. Without limiting the foregoing or any
remedies available to the holders of Rights, it is specifically acknowledged
that the holders of Rights would not have an adequate remedy at law for any
breach of this Agreement and will be entitled to specific performance of the
obligations hereunder and injunctive relief against actual or threatened
violations of the obligations of any Person subject to this Agreement.

     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 Stock;

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

          (c) subject to Sections 6 and 7(f), the Company and the Rights Agent
may deem and treat the Person in whose name the Rights Certificate (or, prior to
the Distribution Date, the associated Common Stock certificate) is registered as
the absolute owner thereof and of the Rights evidenced thereby (notwithstanding
any notations of ownership or writing on the Right Certificates or the
associated Common Stock certificate made by anyone other than the Company or the
Rights Agent) for all purposes whatsoever, and neither the

                                       26
<PAGE>
Company nor the Rights Agent, subject to the last sentence of Section 7(e),
shall be affected by any notice to the contrary; and

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

     17. Rights Certificate Holder Not Deemed a Shareholder. No holder, as such,
of any Rights Certificate shall be entitled to vote, receive dividends or be
deemed for any purpose the holder of the number of one one-hundredths of a share
of Preferred Stock or any other securities of the Company which may at any time
be issuable on the exercise of the Rights represented thereby, nor shall
anything contained herein or in any Rights Certificate be construed to confer
upon the holder of any Rights Certificate, as such, any of the rights of a
shareholder of the Company or any right to vote for the election of directors or
upon any matter submitted to shareholders at any meeting thereof, or to give or
withhold consent to any corporate action, or to receive notice of meetings or
other actions affecting shareholders (except as provided in Section 23(c)), or
to receive dividends or subscription rights, or otherwise, until the Rights
evidenced by such Rights Certificate shall have been exercised in accordance
with the provisions hereof.

     18. Concerning the Rights Agent.

          (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
other disbursements incurred in the administration and execution of this
Agreement and the exercise and performance of its duties hereunder. The Company
also agrees to indemnify the Rights Agent for, and to hold it harmless against,
any loss, liability, or expense incurred without negligence, bad faith or
willful misconduct on the part of the Rights Agent, for anything done or omitted
by the Rights Agent in connection with the acceptance and administration of this
Agreement, including the costs and expenses of defending against any claim of
liability.

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

                                       27
<PAGE>
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.

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

          (a) Any corporation into which the Rights Agent or any successor
Rights Agent may be merged or with which it may be consolidated, or any
corporation resulting from any merger or consolidation to which the Rights Agent
or any successor Rights Agent shall be a party, or any corporation succeeding to
the corporate trust business or stock transfer business of the Rights Agent or
any successor rights agent, shall be the successor to the Rights Agent under
this Agreement without the execution or filing of any paper or any further act
on the part of any of the parties hereto, provided that such corporation would
be eligible for appointment as a successor Rights Agent under the provisions of
Section 21. 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.

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

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

          (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking or suffering any action
hereunder, such fact or matter (unless other evidence in respect thereof be
herein specifically prescribed) may be

                                       28
<PAGE>
deemed to be conclusively provided and established by a certificate signed by
any one of the President, any Vice President, the Treasurer or the Secretary of
the Company and delivered to the Rights Agent; and such certificate shall be
full authorization to the Rights Agent for any action taken or suffered in good
faith by it under the provisions of this Agreement in reliance upon such
certificate.

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

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

          (e) The Rights Agent shall not be under any responsibility in respect
of the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Rights Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Rights Certificate; nor shall it
be responsible for any change in the exercisability of the Rights (including the
Rights becoming void pursuant to Section 7(e) hereof) or any adjustment in the
terms of the Rights (including the manner, method or amount thereof) provided
for in this Agreement 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 actual notice that such change or
adjustment is required); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any shares
of Preferred Stock or Common Stock to be issued pursuant to this Agreement or
any Right Certificate or as to whether any shares of Preferred Stock or Common
Stock will, when issued, be validly authorized and issued, fully paid and
nonassessable.

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

          (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 President, any Vice President, the
Secretary or the Treasurer of the Company, and to apply to such officers for
advice or instructions in connection with its duties, and it shall not be liable
for any action taken or suffered by it in good faith in accordance with
instructions of any such officer or for any delay in acting while waiting for
those instructions. Any application by the 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

                                       29
<PAGE>
or omitted by the Rights Agent under this Agreement and the date on or after
which such action shall be taken or such omission shall be effective. The Rights
Agent shall not be liable for any action taken by, or omission of, the Rights
Agent in accordance with a proposal included in any such application on or after
the date specified in such application (which date shall not be less than five
Business Days after the date any such 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
or omitted.

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

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

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

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

     21. Change of Rights Agent. The Rights Agent or any successor Rights Agent
may resign and be discharged from its duties under this Agreement upon 30 days
notice in writing mailed to the Company and to each transfer agent of the Common
Stock and Preferred Stock by registered or certified mail, and to the holders of
the Rights Certificates by first-class mail. The Company may remove the Rights
Agent or any successor Rights Agent upon 30 days notice in writing, mailed to
the Rights Agent or successor Rights Agent,

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

     22. Issuance of New Rights Certificates. Notwithstanding any of the
provisions of this Agreement or of the Rights to the contrary, the Company may,
at its option, issue new Rights Certificates evidencing Rights in such form as
may be approved by its Board of Directors to reflect any adjustment or change in
the Purchase Price and the number or kind or class of shares or other securities
or property purchasable under the Rights Certificates made in accordance with
the provisions of this Agreement. In addition, in connection with the issuance
or sale of Common Stock of the Company following the Distribution Date and prior
to the Final Expiration Date, the Company (a) shall, with respect to Common
Stock of the Company 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 securities issued by the Company prior to the Distribution Date, and
(b) may, in any other case, if deemed necessary or appropriate by the Board of
Directors, issue Rights Certificates representing the appropriate number of
Rights in connection with such issuance or sale; provided, however, that (i) no
such Rights Certificate shall be issued if, and to the extent that, the Company
shall be advised by counsel that such issuance would create a significant risk
of material adverse tax consequences to the Company or the person to whom such
Rights

                                       31
<PAGE>
Certificate would be issued, and (ii) no such Rights Certificate shall be issued
if, and to the extent that, appropriate adjustment shall otherwise have been
made in lieu of the issuance thereof.

     23. Redemption.

          (a) The Board of Directors of the Company may at its option, at any
time prior to the earliest of (i) the close of business on the tenth day
following a Stock Acquisition Date (or, if the Stock Acquisition Date shall have
occurred prior to the Record Date, the close of business on the tenth day
following the Record Date), (ii) a determination by the Board of Directors that
any Person is an Adverse Person, or (iii) the Final Expiration Date, redeem all
but not less than all the then outstanding Rights at a redemption price of $.001
per Right, appropriately adjusted to reflect any stock split, stock dividend or
similar transaction occurring after the date hereof (such redemption price being
hereinafter referred to as the "Redemption Price"). Notwithstanding anything
contained in this Agreement to the contrary, the Rights shall not be exercisable
as provided in Section 11(a)(ii) until such time as the Company's right of
redemption hereunder has expired.

          (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights (or at such later time as shall be
specified in the resolution taking such action), 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. Promptly after the action of the Board of Directors ordering
the redemption of the Rights, the Company shall give notice of such redemption
to the holders of the then outstanding Rights and the Rights Agent 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 shares of Common Stock. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of redemption will state
the method by which the payment of the Redemption Price will be made. The
Company may, at its option, pay the Redemption Price in cash, shares of Common
Stock (based on the Current Per Share Market Price, as defined in Section 11(d),
of the Common Stock at the time of redemption) or any other form of
consideration deemed appropriate by the Board of Directors.

          (c) In case the Company shall propose (a) to pay any dividend payable
in stock of any class to the holders of its Preferred Stock or Common Stock or
to make any other distribution to the holders of its Preferred Stock or Common
Stock (other than a regular quarterly cash dividend), (b) to offer to the
holders of its Preferred Stock or Common Stock rights or warrants to subscribe
for or to purchase any additional shares of Preferred Stock or Common Stock or
shares of stock of any class or any other securities, (c) to effect any
reclassification of its Preferred Stock or Common Stock (other than a
reclassification involving only the subdivision of outstanding shares of
Preferred Stock or Common Stock), (d) to effect any consolidation, merger or
share exchange into or with any

                                       32
<PAGE>
other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(m)), (e) to effect any sale or other transfer or to
permit one or more of its Subsidiaries to effect any sale or other transfer, in
one or more related transactions, of 50 percent or more of the assets or earning
power of the Company and its Subsidiaries (taken as a whole) to any other Person
(other than the Company and/or any of its Subsidiaries in one or more
transactions each of which complies with Section 11(m)), or (f) to effect the
liquidation, dissolution or winding up of the Company, then, in each such case,
the Company shall give to each holder of a Rights Certificate, to the extent
feasible and in accordance with Section 25, a notice of such proposed action,
which shall specify the record date for the purposes of such stock dividend or
distribution of rights or warrants, or the date on which such reclassification,
consolidation, merger, exchange, sale, transfer, liquidation, dissolution, or
winding up is to take place and the date of participation therein by the holders
of the Preferred Stock or Common Stock if any such date is to be fixed, and such
notice shall be so given in the case of any action covered by clause (a) or (b)
above at least 20 days prior to the record date for determining holders of the
Preferred Stock or Common Stock for purposes of such action, and in the case of
any such other action, at least 20 days prior to the date of the taking of such
proposed action or the date of participation therein by the holders of the
Preferred Stock or Common Stock whichever shall be the earlier.

     In case a Stock Acquisition Date shall occur, the Company shall as soon as
practicable thereafter give to each holder of a Rights Certificate, in
accordance with Section 25, a notice of the occurrence of such event, which
shall specify the event and the consequences of the event to holders of Rights
under Section 11(a)(ii).

     24. Exchange.

          (a) The Board of Directors of the Company may, at its option, at any
time and from time to time after a Stock Acquisition Date, exchange all or part
of the then outstanding and exercisable Rights (which shall not include Rights
that have become void pursuant to the provisions of Section 7(e)) for shares of
Common Stock or Common Stock Equivalents, or any combination thereof, at an
exchange ratio of one share of Common Stock, or such number of Common Stock
Equivalents or units representing fractions thereof as would be deemed to have
the same value as one share of Common Stock, per Right, appropriately adjusted
to reflect any stock split, stock dividend or similar transaction occurring
after the date hereof (such exchange ratio being hereinafter referred to as the
"Exchange Ratio").

          (b) Immediately upon the action of the Board of Directors of the
Company ordering the exchange of any Rights pursuant to subsection (a) of this
Section 24 and without any further action and without any notice, the right to
exercise such Rights shall terminate and the only right thereafter of a holder
of such Rights shall be to receive that number of shares of Common Stock and/or
Common Stock Equivalents equal to the number of such Rights held by such holder
multiplied by the Exchange Ratio. The Company shall promptly give public notice
of any such exchange; provided, however, that the failure to give, or any

                                       33
<PAGE>
defect in, such notice shall not affect the validity of such exchange. The
Company promptly shall mail a notice of any such exchange to all of the holders
of such Rights at their last addresses as they appear upon the registry books of
the Rights Agent. Any notice which is mailed in the manner herein provided shall
be deemed given, whether or not the holder receives the notice. Each such notice
of exchange will state the method by which the exchange of the shares of Common
Stock and/or Common Stock Equivalents 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))
held by each holder of Rights.

          (c) In the event that the number of shares of Common Stock which are
authorized by the Company's Articles of Incorporation as amended but not
outstanding or reserved for issuance for purposes other than upon exercise of
the Rights are not sufficient to permit an exchange of Rights as contemplated in
accordance with this Section 24, the Company may, at its option, take all such
action as may be necessary to authorize additional shares of Common Stock for
issuance upon exchange of the Rights.

          (d) The Company shall not be required to issue fractions of shares of
Common Stock or to distribute certificates which evidence fractional shares of
Common Stock. In lieu of such fractional shares of Common Stock, the company
shall pay to the registered holders of Rights with regard to which such
fractional shares of Common Stock would otherwise be issuable an amount in cash
equal to the same fraction of the value of a whole share of Common Stock. For
purposes of this Section 24, the value of a whole share of Common Stock shall be
the closing price (as determined pursuant to the second sentence of Section
11(d)(i) for the Trading Day immediately prior to the date of exchange pursuant
to this Section 24, and the value of any Common Stock Equivalent shall be deemed
to have the same value as the Common Stock on such date.

     25. Notices. Notices or demands authorized by this Agreement to be given or
made by the Rights Agent or by the holder of any Rights Certificate 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

                         SEQUENT COMPUTER SYSTEMS, INC.
                                  ESTABLISHING
                            SERIES A PREFERRED SHARES


1.   The name of the Corporation is Sequent Computer Systems, Inc.



2.   Article IV, Section 4.3 of the Articles of Incorporation is amended to read
in its entirety as follows:

     4.3  Series A Preferred Stock

     4.3.1. Designation and Amount. The shares of such series shall be
     designated as "Series A Preferred Shares" and the number of shares
     constituting such series shall be 502,000.

     4.3.2. Dividends and Distributions.

          (i) The holders of shares of Series A Preferred Shares shall be
          entitled to receive, when and as declared by the Board of Directors,
          out of funds legally available for the purpose, dividends in an amount
          per share equal to 100 (the "Adjustment Number") multiplied by the
          aggregate per share amount of all cash dividends, and the Adjustment
          Number multiplied by the aggregate per share amount (payable in kind)
          of all non-cash dividends or other distributions other than a dividend
          payable in Common Stock or a subdivision of the outstanding Common
          Stock (by reclassification or otherwise), declared on the Common
          Stock, $.01 par value, of the Corporation (the "Common Stock") after
          the first issuance of any share or fraction of a share of Series A
          Preferred Shares.

          (ii) The Corporation shall declare a dividend or distribution on the
          Series A Preferred Shares as provided in subparagraph 2(i) at the same
          time that it declares a dividend or distribution on the Common Stock
          (other than a dividend payable in Common Stock).

                                       A-1
<PAGE>
          (iii) Dividends shall not be cumulative. Unpaid dividends shall not
          bear interest. Dividends paid on the Series A Preferred Shares 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.

     4.3.3. Voting Rights. The holders of Series A Preferred Shares shall have
     the following voting rights:

          (i) Each Series A Preferred Share shall entitle the holder thereof to
          the number of votes equal to the Adjustment Number then in effect on
          all matters submitted to a vote of the shareholders of the
          Corporation.

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

     4.3.4. Certain Restrictions.

          (i) Whenever dividends or distributions payable on the Series A
          Preferred Shares as provided in Section 2 have not been declared or
          paid for any fiscal year, until all such dividends and distributions
          for such fiscal year on Series A Preferred Shares outstanding shall
          have been declared and paid in full, the Corporation shall not in such
          fiscal year

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

               (b) purchase or otherwise acquire for consideration any Series A
               Preferred Shares or any shares of stock ranking on a parity with
               the Series A Preferred Shares, 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 dividend rates and other relative rights and
               preferences of the respective series and classes, shall determine
               in good faith will result in fair and equitable treatment among
               the respective series or classes.

                                       A-2
<PAGE>
          (ii) 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
          subparagraph 4(i), purchase or otherwise acquire such shares at such
          time and in such manner.

     4.3.5. Restriction on Issuance of Shares; Reacquired Shares. The
     Corporation shall not issue any Series A Preferred Shares except upon
     exercise of rights (the "Rights") issued pursuant to the Rights Agreement
     dated as of April 14, 1998, between the Corporation and ChaseMellon
     Shareholder Services L.L.C., (the "Rights Agreement"), a copy of which is
     on file with the secretary of the Corporation at its principal executive
     office and shall be made available to shareholders of record without charge
     upon written request. Any Series A Preferred Shares purchased or otherwise
     acquired by the Corporation in any manner whatsoever may be restored to the
     status of authorized but unissued shares after the acquisition thereof. All
     such shares shall upon any such restoration become authorized but unissued
     shares of Preferred Shares and may be reissued as part of a new series of
     Preferred Shares to be created by the Board of Directors, subject to the
     conditions and restrictions on issuance set forth herein.

     4.3.6. Liquidation, Dissolution or Winding Up.

          (i) Upon any liquidation (voluntary or otherwise), dissolution or
          winding up of the Corporation, no distribution shall be made to the
          holders of shares of stock ranking junior (either as to dividends or
          upon liquidation, dissolution or winding up) to the Series A Preferred
          Shares unless, prior thereto, the holders of shares of Series A
          Preferred Shares shall have received the Adjustment Number multiplied
          by the per share amount to be distributed to holders of Common Stock,
          plus an amount equal to declared and unpaid dividends and
          distributions thereon to the date of such payment (the "Series A
          Liquidation Preference"). Following the payment of the full amount of
          the Series A Liquidation Preference, no additional distributions shall
          be made to the holders of shares of Series A Preferred Shares.

          (ii) In the event that there are not sufficient assets available to
          permit payment in full of the Series A Liquidation Preference and the
          liquidation preferences of all other series of Preferred Shares, if
          any, which rank senior to or on a parity with the Series A Preferred
          Shares, then assets shall be distributed first to holders of any
          series of Preferred Shares ranking senior to the Series A Preferred
          Shares to the extent of their liquidation preferences and such
          remaining assets shall be distributed ratably to the holders of Series
          A Preferred Shares and such parity shares in proportion to their
          respective liquidation preferences.

                                       A-3
<PAGE>
     4.3.7. Consolidation, Merger, etc. In case the Corporation shall enter into
     any consolidation, merger, combination or other transaction in which the
     Common Stock is exchanged for or changed into other stock or securities,
     cash and/or any other property, then in any such case the Series A
     Preferred Shares shall at the same time be similarly exchanged or changed
     in an amount per share equal to the Adjustment Number multiplied by 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 common
     Share is changed or exchanged.

     4.3.8. Anti-Dilution Adjustments to Adjustment Number. In the event the
     Corporation shall at any time after April 29, 1998 (the "Rights Declaration
     Date") (i) declare any dividend on Common Stock payable in shares of Common
     Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
     outstanding Common Stock into a smaller number of shares, then in each such
     case the Adjustment Number for all purposes of this Article 4 shall be
     adjusted by multiplying the Adjustment Number then in effect by a fraction,
     the numerator of which is the number of shares of Common Stock outstanding
     immediately after such event and the denominator of which is the number of
     shares of Common Stock that were outstanding immediately prior to such
     event. In the event the Corporation shall at any time after the Rights
     Declaration Date, fix a record date for the issuance of rights, options or
     warrants to all holders of Common Stock entitling them (for a period
     expiring within 45 calendar days after such record date) to subscribe for
     or purchase Common Stock or securities convertible into Common Stock at a
     price per Common Stock (or having a conversion price per share, if a
     security convertible into Common Stock) less than the then Current Per
     Share Market Price of the Common Stock (as defined in Section 11(d) of the
     Rights Agreement) on such record date, then in each such case the
     Adjustment Number for all purposes of this Article 4 shall be adjusted by
     multiplying the Adjustment Number then in effect by, a fraction, the
     numerator of which shall be the number of shares of Common Stock
     outstanding on such record date plus the number of additional shares of
     Common Stock to be offered for subscription or purchase (or into which the
     convertible securities so to be offered are initially convertible) and the
     denominator of which shall be the number of shares of Common Stock
     outstanding on such record date plus the number of shares of Common Stock
     which the aggregate offering price of the total number of shares of Common
     Stock so to be offered (and/or the aggregate initial conversion price of
     the convertible securities so to be offered) would purchase at such Current
     Per Share Market Price (as defined in Section 11(d) of the Rights
     Agreement). In case such subscription price may be paid in a consideration
     part or all of which shall be in a form other than cash, the value of such
     consideration shall be as determined in good faith by the Board of
     Directors. Common Stock owned by or held for the account of the Corporation
     shall not be deemed outstanding for the purpose of any such computation.
     Such adjustment shall be made successively whenever such a record date is
     fixed. In the event that such rights, options or warrants are not so
     issued, the

                                       A-4
<PAGE>
     Adjustment Number shall be readjusted as if such record date had not been
     fixed; and to the extent such rights, options or warrants are issued but
     not exercised prior to their expiration, the Adjustment Number shall be
     readjusted to be the number which would have resulted from the adjustment
     provided for in this paragraph 8 if only the rights, options or warrants
     that were exercised had been issued.

     4.3.9. No Redemption. The Series A Preferred Shares shall not be redeemable
     at the option of the Corporation or any holder thereof. Notwithstanding the
     foregoing sentence, the Corporation may acquire Series A Preferred Shares
     in any other manner permitted by law.

     4.3.10. Amendment. Subsequent to the Distribution Date (as defined in the
     Rights Agreement) these Articles of Incorporation shall not be further
     amended in any manner which would materially alter or change the
     preferences, limitations and relative rights of the Series A Preferred
     Shares so as to affect them adversely without the affirmative vote of the
     holders of a majority of the outstanding Series A Preferred shares, voting
     separately as a class.

     4.3.11. Fractional Shares. Series A Preferred Shares may be issued in
     fractions of a share in integral multiples of one one-hundredth of a share,
     which shall entitle the holder, in proportion to such holders 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 Preferred Shares.

3.   The amendment was adopted on November 18, 1997.

4.   Shareholder action was not required to adopt the amendment. The amendment
was adopted by the board of directors without shareholder action.

Rights Certificate with the Form of Election to Purchase and related Certificate
duly executed. The Purchase Price may be paid in cash or by certified check or
cashier's check payable to the order of the Company. The number of Rights
evidenced by this Rights Certificate, the number of one one-hundredths of a
share of Preferred Stock which may be purchased upon exercise hereof, and the
Purchase Price per Right set forth above are the number of Rights, the number of
one one-hundredths of a share and the Purchase Price as of __________, 1998,
based on the Preferred Stock and Common Stock as constituted at such date.

     Upon the occurrence of a Stock Acquisition Date (as such term is defined in
the Rights Agreement), if the Rights evidenced by this Rights Certificate are
beneficially owned by (i) an Acquiring Person or any Affiliate or Associate of
such Acquiring Person (as such terms are defined in the Rights Agreement), (ii)
any other person if such Rights formerly were beneficially owned by such
Acquiring Person (or by an Associate or Affiliate thereof) at a time after such
Acquiring Person, became an Acquiring Person, or (iii) under certain
circumstances specified in the Rights Agreement, a transferee of Rights from
such Acquiring Person (or from any Associate or Affiliate thereof) who became a
transferee prior to or concurrently with such Acquiring Person becoming an
Acquiring Person, such Rights shall become null and void and no holder hereof
shall have any right with respect to such Rights from and after the occurrence
of such an event.

     As provided in the Rights Agreement, the Purchase Price and the number and
kind of shares of Preferred Stock or other securities or property which may be
obtained upon the exercise of the Rights evidenced by this Rights Certificate
are subject to modification and adjustment upon the happening of certain events,
including a Stock Acquisition Date or a Section 13 Event (as such terms are
defined in the Rights Agreement).

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

     This Rights Certificate, with or without other Rights Certificates, upon
surrender at the office or offices of the Rights Agent designated for such
purpose, may be exchanged for another Rights Certificate or Rights Certificates
of like tenor and date evidencing Rights entitling the holder to purchase a like
aggregate number of one one-hundredths of a share of Preferred Stock as the
Rights evidenced by the Rights Certificate or Rights Certificates surrendered
shall have entitled such holder to purchase. If this Rights Certificate shall be

                                       B-2
<PAGE>
exercised in part, the holder shall be entitled to receive upon surrender hereof
another Rights certificate or Rights Certificates for the number of whole Rights
not exercised.

     Subject to the provisions of the Rights Agreement, the Rights evidenced by
this Certificate may be redeemed by the Company at its option at a redemption
price of $.001 per Right at any time prior to the earlier of (i) the close of
business on the tenth day following the Stock Acquisition Date (as such period,
may be extended pursuant to the Rights Agreement) and (ii) the Final Expiration
Date.

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

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

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

                          SUMMARY OF RIGHTS TO PURCHASE
                                PREFERRED SHARES


     Effective as of April 14, 1998, the Board of Directors of Sequent Computer
Systems, Inc. (the "Company") declared a dividend of one Right for each
outstanding share of Common Stock of the Company to shareholders of record at
the close of business on April 29, 1998. Each Right entitles the registered
holder to purchase from the Company one one-hundredth of a share of Series A
Preferred Shares (the "Preferred Shares") at a Purchase Price of $130, subject
to adjustment. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and ChaseMellon
Shareholder Services L.L.C., as Rights Agent.

     Initially, the Rights will be attached to the certificates representing
outstanding shares of Common Stock, and no separate Rights Certificates will be
distributed. The Rights will separate from the Common Stock and a Distribution
Date will occur upon the earlier of (i) ten days following a public announcement
that (A) a person or group of affiliated or associated persons has acquired, or
obtained the right to acquire from shareholders, beneficial ownership of 15
percent or more of the outstanding Common Stock or (B) the Board of Directors of
the Company shall declare any person to be an Adverse Person (as described
below) (each, an "Acquiring Person"), or (ii) ten business days following the
commencement of a tender offer or exchange offer that would result in a person
or group beneficially owning 15 percent or more of such outstanding Common
Stock, as such periods may be extended pursuant to the Rights Agreement.

     An Adverse Person is any person declared to be an Adverse Person by the
Board of Directors upon a determination that such person, alone or together with
its affiliates and associates, has become the beneficial owner of an amount of
Common Stock which the Board of Directors determines to be substantial (which
amount shall be more than 10% of the Common Stock then outstanding) and a
determination by at least a majority of the Board of Directors who are not
officers of the Company, after reasonable inquiry and investigation, including
consultation with such persons as such directors shall deem appropriate, that
(i) such beneficial ownership by such person is intended to cause the Company to
repurchase the Common Stock beneficially owned by such person or to cause
pressure on the Company to take action or enter into a transaction or series of
transactions intended to provide such person with short-term financial gain
under circumstances where the Board of Directors determines that the best
long-term interests of the Company and its shareholders would not be served by
taking such action or entering into such transactions or series of transactions
at that time or (ii) such beneficial ownership is causing or reasonably likely
to cause a material adverse impact (including, but not limited to, impairment of
relationships with customers or

                                       C-1
<PAGE>
impairment of the Company's ability to maintain its competitive position) on the
business or prospects of the Company.

     Until the Distribution Date, (i) the Rights will be evidenced by and will
be transferred with and only with such Common Stock certificates, (ii) new
Common Stock certificates issued after April 29, 1998, will contain a legend
incorporating the Rights Agreement by reference, and (iii) the surrender for
transfer of any certificate for Common Stock will also constitute the transfer
of the Rights associated with the Common Stock represented by such certificate.

     The Rights are not exercisable until the Distribution Date and will expire
at the close of business on April 14, 2008, unless earlier redeemed by the
Company as described below.

     As soon as practicable after the Distribution Date, Rights Certificates
will be mailed to holders of record of the Common Stock as of the close of
business on the Distribution Date, and thereafter, the separate Rights
Certificates alone will represent the Rights. Except as otherwise determined by
the Board of Directors, only Common Stock issued prior to the time the Rights
become exercisable or issued upon exercise or conversion of rights, warrants,
options or convertible securities issued prior to the time the Rights become
exercisable will be issued with Rights.

     In the event that any person becomes an Acquiring Person, each holder of a
Right shall thereafter have the right to receive, upon exercise, in lieu of
Preferred Shares, Common Stock of the Company (or, in certain circumstances,
cash, property or other securities of the Company) having a value equal to two
times the exercise price of the Right. However, Rights are not exercisable as
described in this paragraph until such time as the Rights are no longer
redeemable by the Company as set forth below. Notwithstanding any of the
foregoing, if any person becomes an Acquiring Person all Rights that are, or
(under certain circumstances specified in the Rights Agreement) were,
beneficially owned by an Acquiring Person will become null and void.

     For example, at an exercise price of $130 per Right, each Right not owned
by the Acquiring Person (or by certain related parties or transferees) following
the event set forth in the preceding paragraph would entitle its holder to
purchase $260 worth of Common Stock (or other consideration, as noted above) for
$130. Assuming that the Common Stock had a per share value of $20 at such time,
the holder of each valid Right would be entitled to purchase thirteen shares of
Common Stock for $130.

     In the event that, at any time following the Distribution Date, (i) the
Company is acquired in a merger or other business combination transaction in
which the Company is not the surviving corporation or in which the Common Stock
are exchanged for stock or other securities or property, or (ii) 50 percent or
more of the Company's assets or earning power is sold or transferred, each
holder of a Right (except Rights which previously have been

                                       C-2
<PAGE>
voided as set forth above) shall thereafter have the right to receive, upon
exercise, common stock of the acquiring company having a value equal to two
times the exercise price of the Right.

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

     With certain exceptions, no adjustment in the Purchase Price or the number
of Preferred Shares issuable upon exercise of a Right will be required until
cumulative adjustments would require an increase or decrease of at least 1
percent. No fractional Preferred Shares will be issued (other than fractions
which are integral multiples of one one-hundredth of a share of Preferred
Shares) and, in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading date prior to the date
of exercise.

     At any time until a determination that any person is an Adverse Person or
ten days (or longer if extended pursuant to the terms of the Rights Agreement)
after a person otherwise becomes an Acquiring Person, the Company may redeem the
Rights in whole, but not in part, at a price of $.001 per Right (payable in
cash, Common Stock or other consideration), appropriately adjusted to reflect
any stock split, stock dividend or similar transaction occurring after the date
hereof. Immediately upon the action of the Board of Directors ordering
redemption of the Rights, the Rights will terminate and the only right of the
holders of Rights will be to receive the $.001 redemption price.

     At any time after a person becomes an Acquiring Person, the Board of
Directors of the Company may exchange the Rights (other than Rights owned by
such person or group which become void), in whole or in part, at an exchange
ratio of one Common Stock, or one one-hundredth of a share of Preferred Shares
(or of a share of a class or series of the Company's preferred stock having
equivalent rights, preferences and privileges), per Right (subject to
adjustment).

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a shareholder of the Company, including, without limitation, the right
to vote or to receive dividends. While the distribution of the Rights will not
be taxable to shareholders or to the

                                       C-3
<PAGE>
Company, shareholders may, depending upon the circumstances, recognize taxable
income in the event that the Rights become exercisable for Common Stock (or
other consideration) of the Company or for common stock of the acquiring company
as set forth above.

     The Preferred Shares will be non-redeemable. The Preferred Shares may rank
on a lower priority in respect of the preference as to dividends and the
distribution of assets with other classes or series of the Company's preferred
shares. Each Preferred Share will be entitled to an aggregate of 100 times the
cash and non-cash (payable in kind) dividends and distributions (other than
dividends and distributions payable in Common Shares) declared on the Company's
Common Stock. In the event of liquidation, the holders of Preferred Shares will
be entitled to receive a liquidation payment in an amount equal to 100 times the
payment made per Common Share, plus an amount equal to declared and unpaid
dividends and distributions thereon. In the event of any merger, consolidation
or other transaction in which Common Stock is exchanged, each Preferred Share
will be entitled to receive 100 times the amount received per share of Common
Stock. The dividend and liquidation rights of the Preferred Stock are protected
by antidilution provisions. Each Preferred Share will be entitled to 100 votes
(subject to certain adjustments) on all matters submitted to the shareholders.

     A copy of the Rights Agreement has been filed with the Securities and
Exchange Commission as an exhibit to a Current Report on Form 8-K dated
___________________. A copy of the Rights Agreement is available free of charge
from the Rights Agent. This summary description of the Rights does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, which is incorporated herein by reference.
