Item 5.  OTHER EVENTS

          On November 19, 1998, the Board of Directors of Tosco Corporation (the
"Company") declared a dividend of one Right for each outstanding share of the
Company's Common Stock, par value $.75 per share (the "Common Stock"), to
stockholders of record at the close of business on December 7, 1998 (the "Record
Date"). Each Right entitles the registered holder to purchase from the Company a
unit consisting of one one-hundredth of a share of Series A Junior Participating
Preferred Stock, par value $1.00 per share (the "Preferred Stock"), at a
Purchase Price of $90.00 per unit of one one-hundredth of a share, subject to
adjustment. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and BankBoston N.A., as
Rights Agent.

          Initially, the Rights will be attached to all Common Stock
certificates representing shares then outstanding, and no separate Rights
Certificates will be distributed. The Rights will separate from the Common Stock
and a Distribution Date will occur upon the earliest of (i) 10 days following a
public announcement that a person or group of affiliated or associated persons
(other than those who report ownership on Schedule 13G under the Securities
Exchange Act of 1934) (an "Acquiring Person") has acquired, or obtained the
right to acquire, beneficial ownership of 15% or more of the shares of Common
Stock then outstanding1 (the "Stock Acquisition Date"), (ii) 10 business days
following the commencement of a tender offer or exchange offer that would result
in a person or group beneficially owning 15% or more of such outstanding shares
of Common Stock, or (iii) 10 business days following the date the Board of
Directors declares a person to be an "Adverse Person," upon a determination by
the Board that such person, alone or together with his affiliates or associates,
is or has become the beneficial owner of 10% or more of the shares of Common
Stock outstanding, and upon a determination by the Board of Directors of the
Company, after reasonable inquiry and investigation, including consultation with
such persons as such directors shall deem appropriate, that (a) such beneficial
ownership by such person is intended to cause the Company to repurchase the
shares of 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 stockholders would not be served by taking such
action or entering into such transactions or series of transactions at that
time, or (b) 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, financial condition, competitive
position or prospects of the Company.

- ---------------
1        Under the Rights Agreement, for purposes of calculating percentages of
         Common Stock outstanding, shares of Common Stock outstanding shall
         include all shares of Common Stock deemed to be beneficially owned by a
         Person and its affiliates and associates, even if not actually then
         outstanding.
<PAGE>

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

          The Rights are not exercisable until the Distribution Date and will
expire at the close of business on December 6, 2008 (the "Final Expiration
Date"), 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 (i) with respect to certain
shares of Common Stock issued or sold pursuant to the exercise of stock options
or under any employee benefit plan or compensation arrangement, or upon the
exercise, conversion or exchange of certain securities of the Company, or (ii)
as otherwise determined by the Board of Directors, only shares of Common Stock
issued prior to the Distribution Date will be issued with Rights.

          In the event that (i) a person or group becomes the beneficial owner
of 15% or more of the then outstanding shares of Common Stock (except pursuant
to a tender offer or an exchange offer for all outstanding shares of Common
Stock at a price and on terms which a majority of the Directors who are not
officers of the Company and who are not representatives, nominees, affiliates or
associates of such person, with the concurrence of a majority of the Continuing
Directors (as defined below), after receiving advice from one or more nationally
recognized investment banking firms, determines to be fair to and otherwise in
the best interests of the Company and its stockholders (a "Qualifying Offer")),
or (ii) the Board of Directors declares that a person is an Adverse Person (each
such event, a "Flip-in Event"), each holder of a Right will thereafter have the
right to receive, upon exercise of such Right, Common Stock (or, in certain
circumstances, cash, property or other securities of the Company) having a value
(based on a formula set forth in the Rights Agreement) equal to two times the
Purchase Price of the Right. Notwithstanding any of the foregoing, following the
occurrence of any Flip-in Event, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by any
Acquiring Person or an Adverse Person (or by certain related parties) will be
null and void. However, Rights are not exercisable following the occurrence of
any Flip-in Event until such time as the Rights are no longer redeemable by the
Company as set forth below.

          For example, at a Purchase Price of $90.00 per Right, each Right not
owned by an Acquiring Person or an Adverse Person (or by certain related
parties) following a Flip-in Event would entitle its holder to purchase $180.00
worth of Common Stock (or other consideration, as noted above) determined
pursuant to a formula set forth in the Rights Agreement, for $90.00. Assuming
that the Common Stock had a per share value of $45.00 at such time (as
determined pursuant to such formula), the holder of each valid Right would be
entitled to purchase four shares of Common Stock for $90.00.

          In the event that, at any time following the Stock Acquisition 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 it
is the surviving corporation, (ii) the Company engages in a merger or other
business combination transaction in which the Company is the surviving
corporation but its Common Stock is changed or exchanged for stock or securities
of any other person or cash or any other property (other than a merger meeting
certain conditions which follows an offer for all outstanding shares of Common
Stock which a majority of the unaffiliated Directors who are not officers of the
Company determine to be fair to and otherwise in the best interests of the
Company and its stockholders), or (iii) 50% or more of the Company's assets or
earning power is sold or transferred (in one transaction or a series of
transactions) (each such event, a "Flip-Over Event"), then 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 at the then current Purchase
Price (as set forth in the Rights Agreement), common stock of the acquiring
company having a then current market value equal to two times the exercise price
of the Right. The events set forth in this paragraph and the Flip-in Events
described in the second preceding paragraph are referred to as the "Triggering
Events."

          The Company may not engage in a transaction with an Acquiring Person
constituting a Flip-Over Event unless the Acquiring Person meets certain
conditions. If the Acquiring Person's (or its affiliated entity's) common stock
has not been registered under the Securities Exchange Act of 1934, as amended,
for the preceding twelve months, but it is a direct or indirect subsidiary of
another company which has registered common stock, the Rights shall be
exercisable as described above to purchase the common stock of such parent
company. Moreover, the Company may not engage in a flip-over transaction unless
the Acquiring Person (or its affiliated entity or parent, as applicable), (i)
has sufficient shares of common stock authorized to permit the full exercise of
the Rights and (ii) enters into an agreement containing the terms set forth
above and providing that, as soon as practicable after the date of the Flip-Over
Event, the Acquiring Person will register the Rights and the securities issuable
upon exercise of the Rights under the Securities Act of 1933, as amended, and
maintain the effectiveness of such registration statement until the Expiration
Date of the Rights Plan. Notwithstanding the foregoing, a merger or
consolidation will not constitute a Flip-Over Event if (i) the transaction is
consummated with a person who acquired Common Stock pursuant to Qualifying Offer
or with a subsidiary of such person; (ii) the price per share of Common Stock
offered in such transaction is not less than the price paid to holders of the
Company's Common Stock whose shares were purchased in the Qualifying Offer; and
(iii) the form of consideration offered in the transaction is the same as the
form of consideration paid pursuant to the Qualifying Offer.

          The Purchase Price payable, and the number of units of shares of
Preferred Stock or other securities or property issuable, upon exercise of the
Rights are subject to adjustment from time to time to prevent dilution (i) in
the event of a stock dividend on, or a subdivision, combination or
reclassification of, the Preferred Stock, (ii) if holders of the Preferred Stock
are granted certain rights or warrants to subscribe for Preferred Stock or
convertible securities at less than the current market price of the Preferred
Stock, or (iii) upon the distribution to holders of the Preferred Stock of
evidences of indebtedness or assets (excluding regular quarterly cash dividends)
or of subscription rights or warrants (other than those referred to above). With
certain exceptions, no adjustment in the Purchase Price will be required until
cumulative adjustments amount to at least 1% of the Purchase Price. No
fractional shares of Preferred Stock (other than fractions of one one-hundredth
of a share, or integral multiples thereof) will be issued and, in lieu thereof,
an adjustment in cash will be made based on the market price of the Preferred
Stock on the last trading date prior to the date of exercise.

          At any time until the earlier of (a) ten days following the Stock
Acquisition Date or (b) the Final Expiration Date, the Company may redeem the
Rights in whole, but not in part, at a price of $.01 per Right (payable in cash,
Common Stock or other consideration deemed appropriate by the Board of
Directors). Under certain circumstances set forth in the Rights Agreement, the
decision to redeem shall require the concurrence of a majority of the Continuing
Directors. The Company may not redeem the Rights if the Board of Directors has
previously declared a person to be an Adverse Person. Immediately upon the
action of the Board of Directors ordering redemption of the Rights, with, where
required, the concurrence of such Continuing Directors, the Rights will
terminate and the only right of the holders of Rights will be to receive the
$.01 redemption price. In the event that a majority of the members of the Board
serving following a meeting of stockholders or stockholder action by written
consent are not nominated by the Board serving immediately prior to such meeting
or action, then for 180 days following such meeting or action the Rights may not
be redeemed if such redemption is reasonably likely to have the purpose or
effect of allowing any person to become an Acquiring Person, or otherwise
facilitating the occurrence of a Flip-In Event, or a Flip-Over Event or a
transaction with an Acquiring Person.

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

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

          Other than certain provisions relating to the principal economic terms
of the Rights, any of the provisions of the Rights Agreement may be amended by
the Board of Directors of the Company prior to the Distribution Date. After the
Distribution Date, the provisions of the Rights Agreement may be amended by the
Board (in certain circumstances, with the concurrence of the Continuing
Directors) in order to cure any ambiguity, defect or inconsistency, to make
changes which do not adversely affect the interests of holders of Rights (other
than an Acquiring Person, an Adverse Person or an affiliate or associate
thereof), or to shorten or lengthen any time period under the Rights Agreement;
PROVIDED, however, that an amendment to lengthen the time period governing
redemption may be made only if the Rights are redeemable and an amendment to
lengthen any other time period may be made only for the purpose of protecting,
enhancing or clarifying the rights of, and/or benefits to, the holders of Rights
(other than any Acquiring Person or Adverse Person).

          The Rights will have certain anti-takeover effects. Exercise of the
Rights will cause substantial dilution to a person or group that attempts to
acquire the Company on terms not approved by the Company's Board of Directors.
The existence of Rights, however, should not affect an offer at a fair price and
otherwise in the best interests of the Company and its stockholders as
determined by the Board of Directors. The Rights should not interfere with any
merger or other business combination approved by the Board of Directors since
the Board of Directors may, at its option, at any time until ten days following
the Stock Acquisition Date or until a person has been determined to be an
Adverse Person redeem all but not less than all of the then outstanding Rights
at the $.01 redemption price.

          The Rights Agreement between the Company and the Rights Agent
specifying the terms of the Rights, which includes as an exhibit the form of
Rights Certificate, is incorporated herein by reference. The foregoing
description of the Rights does not purport to be complete and is qualified in
its entirety by reference to the Rights Agreement.

                                RIGHTS AGREEMENT

          RIGHTS AGREEMENT, dated as of November 19, 1998 (the "Agreement"),
between Tosco Corporation, a Nevada corporation (the "Company"), and BankBoston
N.A. (the "Rights Agent").


                               W I T N E S S E T H

          WHEREAS, the Board of Directors of the Company has authorized and
declared a dividend distribution of one Right for each share of common stock,
par value $.75 per share, of the Company (the "Common Stock") outstanding at the
close of business on December 7, 1998 (the "Record Date"), and has authorized
the issuance of one Right (as such number may hereinafter be adjusted pursuant
to the provisions of Section 11(p) hereof) for each share of Common Stock of the
Company issued between the Record Date (whether originally issued or delivered
from the Company's treasury) and the Distribution Date (as defined below), each
Right initially representing the right to purchase one one-hundredth (1/100th)
of a share of Series A Junior Participating Preferred Stock (the "Preferred
Stock") of the Company having the rights, powers and preferences set forth in
the form of Certificate of Designation, Preferences and Rights attached hereto
as EXHIBIT A, upon the terms and subject to the conditions hereinafter set forth
(the "Rights");

          WHEREAS, the Company desires to appoint the Rights Agent to act as
provided herein, and the Rights Agent is willing to so act;

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

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

          (a) "Acquiring Person" shall mean any Person who or which, together
with all Affiliates and Associates of such Person, shall be the Beneficial Owner
of 15% or more of the shares of Common Stock then outstanding, but shall not
include (i) the Company, (ii) any Subsidiary of the Company, (iii) any employee
benefit plan or compensation arrangement of the Company or of any Subsidiary of
the Company, (iv) any Person or entity organized, appointed or established by
the Company for or pursuant to the terms of any such plan or (v) any Person who
has reported or is required to report such ownership on Schedule 13G under the
Securities Exchange Act of 1934, as amended and in effect on the date of this
Agreement (the "Exchange Act") (or any comparable or successor report).
Notwithstanding the foregoing, no Person shall become an "Acquiring Person"
solely 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 a Person to 15% or more of the Common Stock of the
Company then outstanding as determined above; PROVIDED, HOWEVER, that if a
Person becomes the Beneficial Owner of 15% or more of the Common Stock of the
Company then outstanding (as determined above) solely by reason of purchases of
Common Stock by the Company and shall, after such purchases by the Company,
become the Beneficial Owner of any additional shares of Common Stock by any
means whatsoever, then such Person shall be deemed to be an "Acquiring Person."
Notwithstanding the foregoing, (i) if the Board of Directors of the Company,
with the concurrence of a majority of the Continuing Directors, 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), then such Person shall not be deemed to be an "Acquiring
Person" for any purposes of this Agreement, or (ii) if a Person becomes the
Beneficial Owner of 15% or more of the Common Stock then outstanding solely as a
result of such Person's entering into an agreement, arrangement or understanding
(including an irrevocable proxy or consent) whereby such Person obtains the
right to vote such Common Stock and prior to the time such agreement,
arrangement or understanding is entered into the Board of Directors, with the
concurrence of a majority of the Continuing Directors, has approved either (x) a
"combination" (as such term is defined in Nevada Revised Statutes 78.416) to
which such Person or an Affiliate of such Person is a party or (y) such
agreement, arrangement or understanding with such Person, then such Person shall
not be deemed to be an "Acquiring Person" for the purposes of this Agreement.

          (b) "Act" shall have the meaning set forth in Section 9(c) hereof.

          (c) "Adjustment Shares" shall have the meaning set forth in Section
11(a)(ii) hereof.

          (d) "Adverse Person" shall mean any Person declared to be an Adverse
Person by the Board of Directors upon determination that the criteria set forth
in Section 11(a)(ii)(B) apply to such Person; PROVIDED, HOWEVER, that the Board
of Directors shall not declare any Person who is the Beneficial Owner of 10% or
more (but less than 15%) of the outstanding Common Stock of the Company to be an
Adverse Person if such Person has reported or is required to report such
ownership on Schedule 13G under the Exchange Act (or any comparable or successor
report) or on Schedule 13D under the Exchange Act (or any comparable or
successor report) which Schedule 13D does not state any intention to or reserve
the right to control or influence the management or policies of the Company or
engage in any of the actions specified in Item 4 of such Schedule (other than
the disposition of the Common Stock) so long as such Person neither reports nor
is required to report such ownership other than as described in this paragraph
(d).

          (e) "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.

          (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
                  right to acquire (whether such right is exercisable
                  immediately or only after the passage of time) pursuant to any
                  agreement, arrangement or understanding (whether or not in

                  agreement, arrangement or understanding, whether or not in
                  writing; PROVIDED, HOWEVER, that a Person shall not be deemed
                  the "Beneficial Owner" of, or to "beneficially own," any
                  security under this subparagraph (ii) as a result of an

                  Affiliates or Associates) has any agreement, arrangement or

Agent.  The Rights Agent shall have no duty to supervise, and shall in no event

          Section 3. ISSUE OF RIGHTS CERTIFICATES.

          (a) Until the earliest of (i) the close of business on the tenth day
after the Stock Acquisition Date (or, if the tenth day after the Stock
Acquisition Date occurs before the Record Date, the close of business on the
Record Date), (ii) the close of business on the tenth business day (or such
later date as the Board of Directors shall determine) after the date that a
tender or exchange offer by any Person (other than the Company, any Subsidiary
of the Company, any employee benefit plan or compensation arrangement of the
Company or of any Subsidiary of the Company, or any Person or entity organized,
appointed or established by the Company for or pursuant to the terms of any such
plan) is first published or sent or given within the meaning of Rule 14d-2(a) of
the General Rules and Regulations under the Exchange Act, if upon consummation
thereof, such Person would be the Beneficial Owner of 15% or more of the shares
of Common Stock then outstanding or (iii) the close of business on the tenth
Business Day after the Board of Directors determines, pursuant to the criteria
set forth in Section 11(a)(ii)(B) hereof, that a Person is an Adverse Person
(the earliest of (i), (ii) and (iii) being herein referred to as the
"Distribution Date"), (x) the Rights will be evidenced (subject to the
provisions of paragraph (b) of this Section 3) by the certificates for the
Common Stock registered in the names of the holders of the Common Stock (which
certificates for Common Stock shall be deemed also to be certificates for
Rights) and not by separate certificates, and (y) the Rights will be
transferable only in connection with the transfer of the underlying shares of
Common Stock (including a transfer to the Company). As soon as practicable after
the Distribution Date, the Rights Agent will send by first-class, insured,
postage prepaid mail, to each record holder of the Common Stock as of the close
of business on the Distribution Date, at the address of such holder shown on the
records of the Company, one or more rights certificates, in substantially the
form of EXHIBIT B hereto (the "Rights Certificates"), evidencing one Right for
each share of Common Stock so held, subject to adjustment as provided herein. In
the event that an adjustment in the number of Rights per share of Common Stock
has been made pursuant to Section 11(p) hereof, at the time of distribution of
the Rights Certificates, the Company shall make the necessary and appropriate
rounding adjustments (in accordance with Section 14(a) hereof) so that Rights
Certificates representing only whole numbers of Rights are distributed and cash
is paid in lieu of any fractional Rights. As of and after the Distribution Date,
the Rights will be evidenced solely by such Rights Certificates.

          (b) On the Record Date, or as soon as practicable thereafter, the
Company will send a copy of a Summary of Rights by first-class, postage prepaid
mail, to each record holder of the Common Stock as of the close of business on
the Record Date, at the address of such holder shown on the records of the
Company. With respect to certificates for the Common Stock outstanding as of the
Record Date, until the Distribution Date, the Rights will be evidenced by such
certificates for the Common Stock and the registered holders of the Common Stock
shall also be the registered holders of the associated Rights. Until the earlier
of the Distribution Date or the Expiration Date (as such term is defined in
Section 7 hereof), the transfer of any certificates representing shares of
Common Stock in respect of which Rights have been issued shall also constitute
the transfer of the Rights associated with such shares of Common Stock.

          (c) Rights shall be issued in respect of all shares of Common Stock
which are issued (whether originally issued or from the Company's treasury)
after the Record Date but prior to the earlier of the Distribution Date or the
Expiration Date or in certain circumstances provided in Section 22 hereof, after
the Distribution Date. Certificates representing such shares of Common Stock
shall also be deemed to be certificates for Rights, and shall bear a legend
reading substantially as follows:

                    This certificate also evidences and entitles the holder
                    hereof to certain Rights as set forth in the Rights
                    Agreement between Tosco Corporation (the "Company") and
                    BankBoston N.A. (the "Rights Agent"), dated as of November
                    19, 1998, as amended from time to time (the "Rights
                    Agreement"), the terms of which are hereby incorporated
                    herein by reference and a copy of which is on file at the
                    principal office 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 or
                    the Rights Agent will mail to the holder of this certificate
                    a copy of the Rights Agreement, as in effect on the date of
                    mailing, without charge promptly after receipt of a written
                    request therefor. Under certain circumstances set forth in
                    the Rights Agreement, Rights issued to, or held by, any
                    Person who is, was or becomes an Acquiring Person, an
                    Adverse Person or any Affiliate or Associate thereof (as
                    such terms are defined in the Rights Agreement), whether
                    currently held by or on behalf of such Person or by any
                    subsequent holder, may become null and void.

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

          Section 4. FORM OF RIGHTS CERTIFICATES.

          (a) The Rights Certificates (and the forms of election to purchase and
of assignment to be printed on the reverse thereof) shall each be substantially
in the form set forth in EXHIBIT B hereto and may have such marks of
identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be required to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange or quotation system on which the Rights
may from time to time be listed, or to conform to usage. Subject to the
provisions of Section 11 and Section 22 hereof, the Rights Certificates,
whenever distributed, shall be dated as of the Record Date and on their face
shall entitle the holders thereof to purchase such number of one one-hundredths
(1/100ths) of a share of Preferred Stock as shall be set forth therein at the
price set forth therein (such exercise price per one one-hundredth (1/100th) of
a share, the "Purchase Price"), but the amount and type of securities
purchasable upon the exercise of each Right and the Purchase Price thereof shall
be subject to adjustment as provided herein.

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

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

The failure to print the foregoing legend on any such Right Certificate or any
defect therein shall not affect in any manner whatsoever the application or
interpretation of the provisions of Section 7(e) hereof.

          Section 5. COUNTERSIGNATURE AND REGISTRATION.

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

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

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

          (a) Subject to the provisions of Section 4(b), Section 7(e) and
Section 14 hereof, at any time after the close of business on the Distribution
Date, and at or prior to the close of business on the Expiration Date, any
Rights Certificate or Certificates (other than Rights Certificates representing
Rights that have been exchanged pursuant to Section 24 hereof) may be
transferred, split up, combined or exchanged for another Rights Certificate or
Certificates, entitling the registered holder to purchase a like number of one
one-hundredths (1/100ths) of a share of Preferred Stock (or, following a
Triggering Event, Common Stock, other securities, cash or other assets, as the
case may be) as the Rights Certificate or Certificates surrendered then entitled
such holder (or former holder in the case of a transfer) to purchase. Any
registered holder desiring to transfer, split up, combine or exchange any Rights
Certificate or Certificates shall make such request in writing delivered to the
Rights Agent, and shall surrender the Rights Certificate or Certificates to be
transferred, split up, combined or exchanged at the principal office or offices
of the Rights Agent designated for such purpose. Neither the Rights Agent nor
the Company shall be obligated to take any action whatsoever with respect to the
transfer of any such surrendered Rights Certificate until the registered holder
shall have completed and signed the certificate contained in the form of
assignment on the reverse side of such Rights Certificate and shall have
provided such additional evidence of the identity of the Beneficial Owner (or
former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request. Thereupon the Rights Agent shall, subject to Section
4(b), Section 7(e), Section 14 and Section 24 hereof, countersign and deliver to
the Person entitled thereto a Rights Certificate or Rights Certificates, as the
case may be, as so requested. The Company may require payment of a sum
sufficient to cover any tax or governmental charge that may be imposed in
connection with any transfer, split up, combination or exchange of Rights
Certificates.

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

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

          (a) Subject to Section 7(e) hereof, the registered holder of any

otherwise provided herein including, without limitation, the restrictions on

hereof) in whole or in part at any time after the Distribution Date upon

close of business on December 6, 2008 (the "Final Expiration Date"), (ii) the
time at which the Rights are redeemed as provided in Section 23 hereof or (iii)
the time at which such Rights are exchanged pursuant to Section 24 hereof (the
earliest of (i), (ii) and (iii) being herein referred to as the "Expiration
Date").

          (b) The Purchase Price for each one one-hundredth (1/100th) of a share
of Preferred Stock pursuant to the exercise of a Right shall initially be
$90.00, and shall be subject to adjustment from time to time as provided in
Sections 11 and 13(a) hereof and shall be payable in accordance with paragraph
(c) below.

          (c) Upon receipt of a Rights Certificate representing exercisable
Rights, with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price per one one-hundredth (1/100th) of a share of Preferred Stock (or other
shares, securities, cash or other assets, as the case may be) to be purchased as
set forth below and an amount equal to any applicable transfer tax, the Rights
Agent shall, subject to Section 20(k) hereof, thereupon promptly (i) (A)
requisition from any transfer agent of the shares of Preferred Stock (or make
available, if the Rights Agent is the transfer agent for such shares)
certificates for the total number of one one-hundredths (1/100ths) of a share of
Preferred Stock to be purchased and the Company hereby irrevocably authorizes
its transfer agent to comply with all such requests, or (B) if the Company shall
have elected to deposit the total number of shares of Preferred Stock issuable
upon exercise of the Rights hereunder with a depositary agent, requisition from
the depositary agent depositary receipts representing such number of one
one-hundredths (1/100ths) of a share of Preferred Stock as are to be purchased
(in which case certificates for the shares of Preferred Stock represented by
such receipts shall be deposited by the transfer agent with the depositary
agent) and the Company will direct the depositary agent to comply with such
request, (ii) requisition from the Company the amount of cash, if any, to be
paid in lieu of fractional shares in accordance with Section 14 hereof, (iii)
after receipt of such certificates or depositary receipts, cause the same to be
delivered to or upon the order of the registered holder of such Rights
Certificate, registered in such name or names as may be designated by such
holder, and (iv) after receipt thereof, deliver such cash, if any, to or upon
the order of the registered holder of such Rights Certificate. The payment of
the Purchase Price (as such amount may be reduced pursuant to Section 11(a)(iii)
hereof) shall be made in cash or by certified bank check or bank draft payable
to the order of the Company. In the event that the Company is obligated to issue
other securities (including Common Stock) of the Company, pay cash and/or
distribute other property pursuant to Section 11(a) hereof, the Company will
make all arrangements necessary so that such other securities, cash and/or other
property are available for distribution by the Rights Agent, if and when
appropriate. The Company reserves the right to require prior to the occurrence
of a Triggering Event that, upon any exercise of Rights, a number of Rights be
exercised so that only whole shares of Preferred Stock would be issued.

          (d) In case the registered holder of any Rights Certificate shall
exercise less than all the Rights evidenced thereby, a new Rights Certificate
evidencing Rights equivalent to the Rights remaining unexercised shall be issued
by the Rights Agent and delivered to, or upon the order of, the registered
holder of such Rights Certificate, registered in such name or names as may be
designated by such holder, subject to the provisions of Section 14 hereof.

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

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

          Section 8. CANCELLATION AND DESTRUCTION OF RIGHTS CERTIFICATES. All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or any of its
agents, be delivered to the Rights Agent for cancellation or in 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.

          Section 9. RESERVATION AND AVAILABILITY OF CAPITAL Stock.

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

          (b) So long as the shares of Preferred Stock (and, following the
occurrence of a Triggering Event, Common Stock and/or other securities) issuable
and deliverable upon the exercise of the Rights may be listed on any national
securities exchange or automated quotation system, the Company shall use its
reasonable efforts to cause, from and after such time as the Rights become
exercisable, all shares reserved for such issuance to be listed on such exchange
or automated quotation system upon official notice of issuance upon such
exercise.

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

          (d) The Company covenants and agrees that it will take all such action
as may be necessary to ensure that all one one-hundredths (1/100ths) of a share
of Preferred Stock (and, following the occurrence of a Triggering Event, Common
Stock and/or other securities) delivered upon exercise of Rights shall, at the
time of delivery of the certificates for such shares (subject to payment of the
Purchase Price), be duly and validly authorized and issued and fully paid and
nonassessable.

          (e) The Company further covenants and agrees that it will pay when due
and payable any and all federal and state transfer taxes and charges which may
be payable in respect of the issuance or delivery of the Rights Certificates and
of any certificates for a number of one one-hundredths (1/100ths) of a share of
Preferred Stock (or Common Stock and/or other securities, as the case may be)
upon the exercise of Rights. The Company shall not, however, be required to pay
any transfer tax which may be payable in respect of any transfer or delivery of
Rights Certificates to a Person other than, or the issuance or delivery of a
number of one one-hundredths (1/100ths) of a share of Preferred Stock (or Common
Stock and/or other securities, as the case may be) in respect of a name other
than that of, the registered holder of the Rights Certificates evidencing Rights
surrendered for exercise or to issue or deliver any certificates for a number of
one one-hundredths (1/100ths) of a share of Preferred Stock (or Common Stock
and/or other securities, as the case may be) in a name other than that of the
registered holder upon the exercise of any Rights until such tax shall have been
paid (any such tax being payable by the holder of such Rights Certificate at the
time of surrender) or until it has been established to the Company's
satisfaction that no such tax is due.

          Section 10. PREFERRED STOCK RECORD DATE. Each person in whose name any
certificate for a number of one one-hundredths (1/100ths) of a share of
Preferred Stock (or Common Stock and/or other securities, as the case may be) is
issued upon the exercise of Rights shall for all purposes be deemed to have
become the holder of record of such fractional shares of Preferred Stock (or
Common Stock and/or other securities, as the case may be) represented thereby
on, and such certificate shall be dated, the date upon which the Rights
Certificate evidencing such Rights was duly surrendered and payment of the
Purchase Price (and all applicable transfer taxes) was made; PROVIDED, HOWEVER,
that if the date of such surrender and payment is a date upon which the
Preferred Stock (or Common Stock and/or other securities, as the case may be)
transfer books of the Company are closed, such Person shall be deemed to have
become the record holder of such shares (fractional or otherwise) on, and such
certificate shall be dated, the next succeeding Business Day on which the
Preferred Stock (or Common Stock and/or other securities, as the case may be)
transfer books of the Company are open. Prior to the exercise of the Rights
evidenced thereby, the holder of a Rights Certificate shall not be entitled to
any rights of a stockholder of the Company with respect to shares for which the
Rights shall be exercisable, including, without limitation, the right to vote,
to receive dividends or other distributions or to exercise any preemptive
rights, and shall not be entitled to receive any notice of any proceedings of
the Company, except as provided herein.

          Section 11. ADJUSTMENT OF PURCHASE PRICE, NUMBER AND KIND OF SHARES OR
NUMBER OF RIGHTS. The Purchase Price, the number and kind of shares covered by
each Right and the number of Rights outstanding are subject to adjustment from
time to time as provided in this Section 11.

          (a)   (i) In the event the Company shall at any time after the date of
this Agreement (A) declare a dividend on the Preferred Stock payable in shares
of Preferred Stock, (B) subdivide the outstanding Preferred Stock, (C) combine
the outstanding Preferred Stock into a smaller number of shares, or (D) issue
any shares of its capital stock in a reclassification of the Preferred Stock
(including, without limitation, any such reclassification in connection with a
consolidation or merger in which the Company is the continuing or surviving
corporation), except as otherwise provided in this Section 11(a) and Section
7(e) hereof, the Purchase Price in effect at the time of the record date for
such dividend or of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of Preferred Stock or
capital stock, as the case may be, issuable on such date, shall be
proportionately adjusted so that the holder of any Right exercised after such
time shall be entitled to receive, upon payment of the Purchase Price then in
effect, the aggregate number and kind of shares of Preferred Stock or capital
stock, as the case may be, which, if such Right had been exercised immediately
prior to such date and at a time when the Preferred Stock transfer books of the
Company were open, he or she would have owned upon such exercise and been
entitled to receive by virtue of such dividend, subdivision, combination or
reclassification. If an event occurs which would require an adjustment under
both this Section 11(a)(i) and Section 11(a)(ii) hereof, the adjustment provided
for in this Section 11(a)(i) shall be in addition to, and shall be made prior
to, any adjustment required pursuant to Section 11(a)(ii) hereof.

                  (ii) In the event that:

                  (A) any Person (other than the Company, any Subsidiary of the
Company, any employee benefit plan or compensation arrangement of the Company or
of any Subsidiary of the Company, or any Person or entity organized, appointed
or established by the Company for or pursuant to the terms of any such plan),
alone or together with its Affiliates and Associates, shall, at any time after
the Rights Dividend Declaration Date, become an Acquiring Person, unless the
event causing the Person to become an Acquiring Person is (1) a transaction set
forth in Section 13(a) hereof or (2) an acquisition of shares of Common Stock
pursuant to a tender offer or an exchange offer for all outstanding shares of
Common Stock at a price and on terms determined by at least a majority of the
members of the Board of Directors who are not officers of the Company and who
are not representatives, nominees, Affiliates or Associates of an Acquiring
Person, with the concurrence of a majority of the Continuing Directors, after
receiving advice from one or more nationally recognized investment banking
firms, to be (a) at a price which is fair to stockholders (taking into account
all factors which such members of the Board of Directors deem relevant
including, without limitation, prices which could reasonably be achieved if the
Company or its assets were sold on an orderly basis designed to realize maximum
value) and (b) otherwise in the best interests of the Company and its
stockholders (a "Qualifying Offer") or (B) the Board of Directors of the Company
shall declare any Person to be an Adverse Person, upon a determination that such
Person, alone or together with its Affiliates and Associates, has, at any time
after the Rights Dividend Declaration Date, become the Beneficial Owner of a
number of shares of Common Stock which the Board of Directors of the Company
determines to be substantial (which number of shares shall in no event represent
less than 10% of the outstanding shares of Common Stock) and a determination by
the Board of Directors of the Company, after reasonable inquiry and
investigation, including consultation with such Persons as such directors shall
deem appropriate and consideration of such factors as are permitted by
applicable law, that (a) such Beneficial Ownership by such Person is intended to
cause the Company to repurchase the shares of 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 would not be served
by taking such action or entering into such transaction or series of
transactions at the time or (b) 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, financial
condition, competitive position or prospects of the Company;

then, promptly following the occurrence of any event described in Section
11(a)(ii)(A) or (B) hereof, proper provision shall be made so that each holder
of a Right (except as provided below and in Section 7(e) and Section 24 hereof)
shall thereafter have the right to receive, upon exercise thereof at the then
current Purchase Price in accordance with the terms of this Agreement, in lieu
of a number of one one-hundredths (1/100ths) of a share of Preferred Stock, such
number of shares of Common Stock of the Company as shall equal the result
obtained by (x) multiplying the then current Purchase Price by the then number
of one one-hundredths (1/100ths) of a share of Preferred Stock for which a Right
was exercisable immediately prior to the first occurrence of a Section 11(a)(ii)
Event, and (y) dividing that product (which, following such first occurrence,
shall thereafter be referred to as the "Purchase Price" for each Right and for
all purposes of this Agreement) by 50% of the Current Market Price (determined
pursuant to Section 11(d) hereof) per share of Common Stock on the date of such
first occurrence (such number of shares, the "Adjustment Shares").

                  (iii) In the event that the number of shares of Common Stock
which are authorized by the Company's Certificate of Incorporation but not
outstanding or reserved for issuance for purposes other than upon exercise of
the Rights are not sufficient to permit the exercise in full of the Rights in
accordance with the foregoing subparagraph (ii) of this Section 11(a), the
Company shall to the extent permitted by applicable law and any material
agreements then in effect to which the Company is a party (A) determine the
value of the Adjustment Shares issuable upon the exercise of a Right (the
"Current Value"), and (B) with respect to each Right (subject to Section 7(e)
hereof), make adequate provision to substitute for the Adjustment Shares, upon
the exercise of a Right and payment of the applicable Purchase Price, (1) cash,
(2) a reduction in the Purchase Price, (3) Common Stock or other equity
securities of the Company (including, without limitation, shares, or units of
shares, of preferred stock, such as the Preferred Stock, which the Board has
deemed to have essentially the same value or economic rights as shares of Common
Stock (such shares of preferred stock being referred to as "Common Stock
Equivalents")), (4) debt securities of the Company, (5) other assets, or (6) any
combination of the foregoing, having an aggregate value equal to the Current
Value (less the amount of any reduction in the Purchase Price), where such
aggregate value has been conclusively determined by the Board based upon the
advice of a nationally recognized investment banking firm selected by the Board;
PROVIDED, HOWEVER, that if the Company shall not have made adequate provision to
deliver value pursuant to clause (B) above within thirty (30) days following the
later of (x) the first occurrence of a Section 11(a)(ii) Event and (y) the date
on which the Company's right of redemption pursuant to Section 23(a) expires
(the later of (x) and (y) being referred to herein as the "Section 11(a)(ii)
Trigger Date"), then the Company shall be obligated to deliver, upon the
surrender for exercise of a Right and without requiring payment of the Purchase
Price, shares of Common Stock (to the extent available) and then, if necessary,
cash, which shares and/or cash have an aggregate value equal to the Spread. For
purposes of the preceding sentence, the term "Spread" shall mean the excess of
(i) the Current Value over (ii) the Purchase Price. If the Board determines in
good faith that it is likely that sufficient additional shares of Common Stock
could be authorized for issuance upon exercise in full of the Rights, the thirty
(30) day period set forth above may be extended to the extent necessary, but not
more than ninety (90) days after the Section 11(a)(ii) Trigger Date, in order
that the Company may seek shareholder approval for the authorization of such
additional shares (such thirty (30) day period, as it may be extended, is herein
called the "Substitution Period"). To the extent that action is to be taken
pursuant to the first and/or third sentences of this Section 11(a) (iii), the
Company (1) shall provide, subject to Section 7(e) hereof, that such action
shall apply uniformly to all outstanding Rights, and (2) may suspend the
exercisability of the Rights until the expiration of the Substitution Period in
order to seek such shareholder approval for such authorization of additional
shares and/or to decide the appropriate form of distribution to be made pursuant
to such first sentence and to determine the value thereof. In the event of any
such suspension, the Company shall issue a public announcement stating that the
exercisability of the Rights has been temporarily suspended, as well as a public
announcement at such time as the suspension is no longer in effect. For purposes
of this Section 11(a)(iii), the value of each Adjustment Share shall be the
Current Market Price per share of the Common Stock on the Section 11(a)(ii)
Trigger Date and the per share or per unit value of any Common Stock Equivalent
shall be deemed to equal the Current Market Price per share of the Common Stock
on such date. The Board of Directors of the Company may, but shall not be
required to, establish procedures to allocate the right to receive shares of
Common Stock upon the exercise of the Rights among holders of Rights pursuant to
this Section 11(a)(iii).

          (b) In case the Company shall fix a record date for the issuance of
rights (other than the Rights), options or warrants to all holders of Preferred
Stock entitling them to subscribe for or purchase (for a period expiring within
forty-five (45) calendar days after such record date) Preferred Stock (or shares
having the same rights, privileges and preferences as the shares of Preferred
Stock ("Equivalent Preferred Stock")) or securities convertible into Preferred
Stock or Equivalent Preferred Stock at a price per share of Preferred Stock or
per share of Equivalent Preferred Stock (or having a conversion price per share,
if a security convertible into Preferred Stock or Equivalent Preferred Stock)
less than the Current Market Price (as determined pursuant to Section 11(d)
hereof) per share of Preferred Stock on such record date, the Purchase Price to
be in effect after such record date shall be determined by multiplying the
Purchase Price in effect immediately prior to such record date by a fraction,
the numerator of which shall be the number of shares of Preferred Stock
outstanding on such record date, plus the number of shares of Preferred Stock
which the aggregate offering price of the total number of shares of Preferred
Stock and/or Equivalent Preferred Stock so to be offered (and/or the aggregate
initial conversion price of the convertible securities so to be offered) would
purchase at such Current Market Price, and the denominator of which shall be the
number of shares of Preferred Stock outstanding on such record date, plus the
number of additional shares of Preferred Stock and/or Equivalent Preferred Stock
to be offered for subscription or purchase (or into the maximum number of shares
into which the convertible securities so to be offered are initially
convertible). In case such subscription price may be paid by delivery of
consideration part or all of which may be in a form other than cash, the value
of such consideration shall be as conclusively determined in good faith by the
Board of Directors of the Company, whose determination shall be described in a
statement filed with the Rights Agent and shall be binding on the Rights Agent
and the holders of the Rights. Shares of Preferred Stock owned by or held for
the account of the Company shall not be deemed outstanding for the purpose of
any such computation. Such adjustment shall be made successively whenever such a
record date is fixed, and in the event that such rights, options or warrants are
not so issued, the Purchase Price shall be adjusted to be the Purchase Price
which would then be in effect if such record date had not been fixed.

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

          (d)    (i) For the purpose of any computation hereunder, other than
computations made pursuant to Section 11(a)(iii) hereof, the "Current Market
Price" per share of Common Stock on any date shall be deemed to be the average
of the daily closing prices per share of such Common Stock for the thirty (30)
consecutive Trading Days immediately prior to such date, and for purposes of
computations made pursuant to Section 11(a)(iii) hereof, the Current Market
Price per share of Common Stock on any date shall be deemed to be the average of
the daily closing prices per share of such Common Stock for the ten (10)
consecutive Trading Days immediately following such date; PROVIDED, HOWEVER,
that in the event that the Current Market Price per share of the Common Stock is
determined during a period following the announcement by the issuer of such
Common Stock of (A) a dividend or distribution on such Common Stock payable in
shares of such Common Stock or securities convertible into shares of such Common
Stock (other than the Rights), or (B) any subdivision, combination or
reclassification of such Common Stock, and the ex-dividend date for such
dividend or distribution, or the record date for such subdivision, combination
or reclassification shall not have occurred prior to the commencement of the
requisite thirty (30) Trading Day or ten (10) Trading Day period, as set forth
above, then, and in each such case, the Current Market Price shall be properly
adjusted to take into account ex-dividend trading. The closing price for each
day shall be the last sale price, regular way, or, in case no such sale takes
place on such day, the average of the closing bid and asked prices, regular way,
in either case as reported in the principal consolidated transaction reporting
system with respect to securities listed or admitted to trading on the New York
Stock Exchange or, if the shares of Common Stock are not listed or admitted to
trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed on
the principal national securities exchange on which the shares of Common Stock
are listed or admitted to trading or, if the shares of Common Stock are not
listed or admitted to trading on any national securities exchange, the last
quoted price or, if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by the National Association
of Securities Dealers, Inc. Automated Quotation System ("NASDAQ") or such other
system then in use, or, if on any such date the shares of Common Stock are not
quoted by any such organization, the average of the closing bid and asked prices
as furnished by a professional market maker making a market in the Common Stock
selected by the Board. If on any such date no market maker is making a market in
the Common Stock, the fair value of such shares on such date as conclusively
determined in good faith by the Board shall be used. The term "Trading Day"
shall mean a day on which the principal national securities exchange on which
the shares of Common Stock are listed or admitted to trading is open for the
transaction of business or, if the shares of Common Stock are not listed or
admitted to trading on any national securities exchange, a Business Day. If the
Common Stock is not publicly held or not so listed or traded, Current Market
Price per share shall mean the fair value per share as determined in good faith
by the Board, whose determination shall be described in a statement filed with
the Rights Agent and shall be conclusive for all purposes.

                  (ii) For the purpose of any computation hereunder, the Current
Market Price per share of Preferred Stock shall be determined in the same manner
as set forth above for the Common Stock in clause (i) of this Section 11(d)
(other than the last sentence thereof). If the Current Market Price per share of
Preferred Stock cannot be determined in the manner provided above or if the
Preferred Stock is not publicly held or listed or traded in a manner described
in clause (i) of this Section 11(d), the Current Market Price per share of
Preferred Stock shall be conclusively deemed to be an amount equal to 100 (as
such number may be appropriately adjusted for such events as stock splits, stock
dividends and recapitalizations with respect to the Common Stock occurring after
the date of this Agreement) multiplied by the Current Market Price per share of
the Common Stock. If neither the Common Stock nor the Preferred Stock is
publicly held or so listed or traded, Current Market Price per share of the
Preferred Stock shall mean the fair value per share as determined in good faith
by the Board, whose determination shall be described in a statement filed with
the Rights Agent and shall be conclusive for all purposes.

          (e) Anything herein to the contrary notwithstanding, no adjustment in
the Purchase Price shall be required unless such adjustment would require an
increase or decrease of at least one percent (1%) in the Purchase Price;
PROVIDED, HOWEVER, that any adjustments which by reason of this Section 11(e)
are not required to be made shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this Section 11 shall be made
to the nearest cent or to the nearest ten-thousandth of a share of Common Stock
or other share or one-millionth of a share of Preferred Stock, as the case may
be. Notwithstanding the first sentence of this Section 11(e), any adjustment
required by this Section 11 shall be made no later than the earlier of (i) three
(3) years from the date of the transaction which mandates such adjustment, or
(ii) the Expiration Date.

          (f) If as a result of an adjustment made pursuant to Section 11(a)(ii)
or (iii) or Section 13(a) hereof, the holder of any Right thereafter exercised
shall become entitled to receive any shares of capital stock other than
Preferred Stock, thereafter the number of such other shares so receivable upon
exercise of any Right and the Purchase Price thereof shall be subject to
adjustment from time to time in a manner and on terms as nearly equivalent as
practicable to the provisions with respect to the Preferred Stock contained in
Sections 11(a), (b), (c), (e), (g), (h), (i), (j), (k) and (m), and the
provisions of Sections 7, 9, 10, 13 and 14 hereof with respect to the Preferred
Stock shall apply on like terms to any such other shares.

          (g) All Rights originally issued by the Company subsequent to any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of one one-hundredths
(1/100ths) of a share of Preferred Stock purchasable from time to time hereunder
upon exercise of the Rights, all subject to further adjustment as provided
herein.

          (h) Unless the Company shall have exercised its election as provided
in Section 11(i), upon each adjustment of the Purchase Price as a result of the
calculations made in Sections 11(b) and (c), each Right outstanding immediately
prior to the making of such adjustment shall thereafter evidence the right to
purchase, at the adjusted Purchase Price, that number of one one-hundredths
(1/100ths) of a share of Preferred Stock (calculated to the nearest
one-millionth) obtained by (i) multiplying (x) the number of one one-hundredths
(1/100ths) of a share covered by a Right immediately prior to this adjustment,
by (y) the Purchase Price in effect immediately prior to such adjustment of the
Purchase Price, and (ii) dividing the product so obtained by the Purchase Price
in effect immediately after such adjustment of the Purchase Price.

          (i) The Company may elect on or after the date of any adjustment of
the Purchase Price to adjust the number of Rights, in lieu of any adjustment in
the number of one one-hundredths (1/100ths) of a share of Preferred Stock
purchasable upon the exercise of a Right. Each of the Rights outstanding after
the adjustment in the number of Rights shall be exercisable for the number of
one one-hundredths (1/100ths) of a share of Preferred Stock for which a Right
was exercisable immediately prior to such adjustment. Each Right held of record
prior to such adjustment of the number of Rights shall become that number of
Rights (calculated to the nearest one ten-thousandth) obtained by dividing the
Purchase Price in effect immediately prior to adjustment of the Purchase Price
by the Purchase Price in effect immediately after adjustment of the Purchase
Price. The Company shall make a public announcement of its election to adjust
the number of Rights, indicating the record date for the adjustment, and, if
known at the time, the amount of the adjustment to be made. This record date may
be the date on which the Purchase Price is adjusted or any day thereafter, but,
if the Rights Certificates have been issued, shall be at least ten (10) days
later than the date of the public announcement. If Rights Certificates have been
issued, upon each adjustment of the number of Rights pursuant to this Section
11(i), the Company shall, as promptly as practicable, cause to be distributed to
holders of record of Rights Certificates on such record date Rights Certificates
evidencing, subject to Section 14 hereof, the additional Rights to which such
holders shall be entitled as a result of such adjustment, or, at the option of
the Company, shall cause to be distributed to such holders of record in
substitution and replacement for the Rights Certificates held by such holders
prior to the date of adjustment, and upon surrender thereof, if required by the
Company, new Rights Certificates evidencing all the Rights to which such holders
shall be entitled after such adjustment. Rights Certificates so to be
distributed shall be issued, executed and countersigned in the manner provided
for herein (and may bear, at the option of the Company, the adjusted Purchase
Price) and shall be registered in the names of the holders of record of Rights
Certificates on the record date specified in the public announcement.

          (j) Irrespective of any adjustment or change in the Purchase Price or
the number of one one-hundredths (1/100ths) 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-hundredths (1/100ths) of a share and the number of one one-hundredths
(1/100ths) of a share which were expressed in the initial Rights Certificates
issued hereunder.

          (k) Before taking any action that would cause an adjustment reducing
the Purchase Price below the then stated value, if any, of the number of one
one-hundredths (1/100ths) of a share of Preferred Stock issuable upon exercise
of the Rights, the Company shall take any corporate action which may, in the
opinion of its counsel, be necessary in order that the Company may validly and
legally issue fully paid and nonassessable such number of one one-hundredths
(1/100ths) of a share of Preferred Stock at such adjusted Purchase Price.

          (l) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuance to the holder of any Right exercised after such record date
the number of one one-hundredths (1/100ths) 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 (1/100ths) of a share
of Preferred Stock and other capital stock or securities of the Company, if any,
issuable upon such exercise on the basis of the Purchase Price in effect prior
to such adjustment; PROVIDED, HOWEVER, that the Company shall deliver to such
holder a due bill or other appropriate instrument evidencing such holder's right
to receive such additional shares (fractional or otherwise) or securities upon
the occurrence of the event requiring such adjustment.

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

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

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

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

          (q) The failure of the Board of Directors at any time to declare a
Person to be an Adverse Person following such Person becoming the Beneficial
Owner of shares of Common Stock representing 10% or more of the outstanding
shares of Common Stock shall not imply that such Person is not an Adverse Person
or limit the Board of Directors' right at any time in the future to declare such
Person to be an Adverse Person.

          Section 12. CERTIFICATE OF ADJUSTED PURCHASE PRICE OR NUMBER OF
SHARES. Whenever an adjustment is made as provided in Section 11 and Section 13
hereof, the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for such adjustment,
(b) promptly file with the Rights Agent, and with each transfer agent for the
Preferred Stock and the Common Stock, a copy of such certificate, and (c) mail a
brief summary thereof to each holder of a Rights Certificate (or, if prior to
the Distribution Date, to each holder of a certificate representing shares of
Common Stock) in accordance with Section 26 hereof. The Rights Agent shall be
fully protected in relying on any such certificate and on any adjustment therein
contained.

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

          (a) In the event that, following the Stock Acquisition Date, directly
or indirectly, (x) the Company shall consolidate with, or merge with and into,
any other Person (other than a Subsidiary of the Company in a transaction which
complies with Section 11(o) hereof), and the Company shall not be the continuing
or surviving corporation of such consolidation or merger, (y) any Person (other
than a Subsidiary of the Company in a transaction which complies with Section
11(o) hereof) shall consolidate with, or merge with or into, the Company, and
the Company shall be the continuing or surviving corporation of such
consolidation or merger and, in connection with such consolidation or merger,
all or part of the outstanding shares of Common Stock shall be changed into or
exchanged for stock or other securities of any other Person or cash or any other
property, or (z) the Company shall sell or otherwise transfer (or one or more of
its Subsidiaries shall sell or otherwise transfer), in one transaction or a
series of related transactions, assets or earning power aggregating more than
50% of the assets or earning power of the Company and its Subsidiaries (taken as
a whole) to any Person or Persons (other than the Company or any Subsidiary of
the Company in one or more transactions each of which complies with Section
11(o) hereof), then, and in each such case (except as may be contemplated by
Section 13(d) hereof), proper provision shall be made so that: (i) each holder
of a Right, except as provided in Section 7(e) hereof, shall thereafter have the
right to receive, upon the exercise thereof at the then current Purchase Price
in accordance with the terms of this Agreement, such number of validly
authorized and issued, fully paid, non-assessable and freely tradable shares of
Common Stock of the Principal Party (as such term is hereinafter defined), not
subject to any liens, encumbrances, preemptive rights, rights of first refusal
or other adverse claims, as shall be equal to the result obtained by (1)
multiplying the then current Purchase Price by the number of one one-hundredths
(1/100ths) of a share of Preferred Stock for which a Right is exercisable
immediately prior to the first occurrence of a Section 13 Event (or, if a
Section 11(a)(ii) Event has occurred prior to the first occurrence of a Section
13 Event, multiplying the number of such one one-hundredths (1/100ths) of a
share for which a Right was exercisable immediately prior to the first
occurrence of a Section 11(a)(ii) Event by the Purchase Price in effect
immediately prior to such first occurrence), and dividing that product (which,
following the first occurrence of a Section 13 Event, shall be referred to as
the "Purchase Price" for each Right and for all purposes of this Agreement) by
(2) 50% of the Current Market Price (determined pursuant to Section 11(d)(i)
hereof) per share of the Common Stock of such Principal Party on the date of
consummation of such Section 13 Event; (ii) such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such Section 13 Event,
all the obligations and duties of the Company pursuant to this Agreement; (iii)
the term "Company" shall thereafter be deemed to refer to such Principal Party,
it being specifically intended that the provisions of Section 11 hereof shall
apply only to such Principal Party following the first occurrence of a Section
13 Event; (iv) such Principal Party shall take such steps (including, but not
limited to, the reservation of a sufficient number of shares of its Common
Stock) in connection with the consummation of any such transaction as may be
necessary to assure that the provisions hereof shall thereafter be applicable,
as nearly as reasonably may be, in relation to its shares of Common Stock
thereafter deliverable upon the exercise of the Rights; and (v) the provisions
of Section 11(a)(ii) hereof shall be of no effect following the first occurrence
of any Section 13 Event.

          (b) "Principal Party" shall mean:

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

                  (ii) in the case of any transaction described in clause (z) of
the first sentence of Section 13(a), the Person that is the party receiving the
greatest portion of the assets or earning power transferred pursuant to such
transaction or transactions;

PROVIDED, HOWEVER, that in any such case, (1) if the Common Stock of such Person
is not at such time and has not been continuously over the preceding twelve (12)
month period registered under Section 12 of the Exchange Act, and such Person is
a direct or indirect Subsidiary of another Person the Common Stock of which is
and has been so registered, "Principal Party" shall refer to such other Person;
(2) in case such Person is a Subsidiary, directly or indirectly, of more than
one Person, the Common Stocks of two or more of which are and have been so
registered, "Principal Party" shall refer to whichever of such Persons is the
issuer of the Common Stock having the greatest aggregate market value; and (3)
in case such Person is, or is owned directly or indirectly by, a partnership or
joint venture formed by two or more Persons that are not owned, directly or
indirectly, by the same Person, the rules set forth in (1) and (2) above shall
apply to each of the chains of ownership having an interest in such joint
venture as if such party were a "Subsidiary" of both or all of such joint
venturers and the Principal Parties in each such chain shall bear the
obligations set forth in this Section 13 in the same ratio as their direct or
indirect interests in such Person bear to the total of such interests.

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

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

                  (ii) use its best efforts to qualify or register the Rights
and the securities purchasable upon exercise of the Rights under the "blue sky
laws" of such jurisdictions as may be necessary or appropriate; and

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

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

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

          Section 14. FRACTIONAL RIGHTS AND FRACTIONAL SHARES.

          (a) The Company shall not be required to issue fractions of Rights,
except prior to the Distribution Date as provided in Section 11(p) hereof, or to
distribute Rights Certificates which evidence fractional Rights. In lieu of such
fractional Rights, there shall be paid to the registered holders of the Rights
Certificates with regard to which such fractional Rights would otherwise be
issuable, an amount in cash equal to the same fraction of the current market
value of a whole Right. For purposes of this Section 14(a), the current market
value of a whole Right shall be the closing price of the Rights for the Trading
Day immediately prior to the date on which such fractional Rights would have
been otherwise issuable. The closing price of the Rights for any day shall be
the last sale price, regular way, or, in case no such sale takes place on such
day, the average of the closing bid and asked prices, regular way, in either
case as reported in the principal consolidated transaction reporting system with
respect to securities listed or admitted to trading on the New York Stock
Exchange or, if the Rights are not listed or admitted to trading on the New York
Stock Exchange, as reported in the principal consolidated transaction reporting
system with respect to securities listed on the principal national securities
exchange on which the Rights are listed or admitted to trading, or if the Rights
are not listed or admitted to trading on any national securities exchange, the
last quoted price or, if not so quoted, the average of the high bid and low
asked prices in the over-the-counter market, as reported by NASDAQ or such other
system then in use or, if on any such date the Rights are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Rights selected by the Board of
Directors of the Company. If on any such date no such market maker is making a
market in the Rights the fair value of the Rights on such date as conclusively
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 (1/100th) 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 (1/100th) of a share of Preferred Stock). In lieu of fractional shares
of Preferred Stock that are not integral multiples of one one-hundredth
(1/100th) of a share of Preferred Stock, the Company may pay to the registered
holders of Rights Certificates at the time such Rights are exercised as herein
provided an amount in cash equal to the same fraction of the current market
value of one one-hundredth (1/100th) of a share of Preferred Stock. For purposes
of this Section 14(b), the current market value of one one-hundredth (1/100th)
of a share of Preferred Stock shall be one one-hundredth (1/100th) of the
closing price of a share of Preferred Stock (as determined pursuant to Section
11(d)(ii) hereof) for the Trading Day immediately prior to the date of such
exercise.

          (c) Following the occurrence of a Triggering Event, the Company shall
not be required to issue fractions of shares of Common Stock upon exercise of
the Rights or to distribute certificates which evidence fractional shares of
Common Stock. In lieu of fractional shares of Common Stock, the Company may pay
to the registered holders of Rights Certificates at the time such Rights are
exercised as herein provided an amount in cash equal to the same fraction of the
current market value of one (1) share of Common Stock. For purposes of this
Section 14(c), the current market value of one 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 Rights expressly
waives his or her right to receive any fractional Rights or any fractional
shares upon exercise of a Right, except as permitted by this Section 14.

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

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

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

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

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

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

          Section 17. RIGHTS CERTIFICATE HOLDER NOT DEEMED A STOCKHOLDER. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of the number of one
one-hundredths (1/100ths) 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 stockholder of the Company or any right to vote for
the election of directors or upon any matter submitted to stockholders at any
meeting thereof, or to give or withhold consent to any corporate action, or to
receive notice of meetings or other actions affecting stockholders (except as
provided in Section 25 hereof), or to receive dividends or subscription rights,
or otherwise, until the Right or Rights evidenced by such Rights Certificate
shall have been exercised in accordance with the provisions hereof.

          Section 18. CONCERNING THE RIGHTS AGENT.

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

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

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

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

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

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

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

          (b) Whenever in the performance of its duties under this Agreement the
Rights Agent shall deem it necessary or desirable that any fact or matter
(including, without limitation, the identity of any Acquiring Person or Adverse
Person and the determination of Current Market Price) be proved or established
by the Company prior to taking or suffering any action hereunder, such fact or
matter (unless other evidence in respect thereof be herein specifically
prescribed) may be deemed to be conclusively proved and established by a
certificate signed by the Chairman of the Board, the Chief Executive Officer,
the President, any Vice President, the Treasurer, the Secretary or any Assistant
Secretary of the Company and delivered to the Rights Agent; and such certificate
shall be full authorization to the Rights Agent for any action taken or suffered
in good faith by it under the provisions of this Agreement in reliance upon such
certificate.

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

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

          (e) The Rights Agent shall not be under any responsibility in respect
of the validity of this Agreement or the execution and delivery hereof (except
the due execution hereof by the Rights Agent) or in respect of the validity or
execution of any Rights Certificate (except its countersignature thereof); nor
shall it be responsible for any breach by the Company of any covenant or
condition contained in this Agreement or in any Rights Certificate; nor shall it
be responsible for any adjustment required under the provisions of Section 11,
Section 13 or Section 24 hereof or responsible for the manner, method or amount
of any such adjustment or the ascertaining of the existence of facts that would
require any such adjustment (except with respect to the exercise of Rights
evidenced by Rights Certificates after actual notice of any such adjustment);
nor shall it by any act hereunder be deemed to make any representation or
warranty as to the authorization or reservation of any shares of Common Stock or
Preferred Stock to be issued pursuant to this Agreement or any Rights
Certificate or as to whether any shares of Common Stock or Preferred Stock will,
when so issued, be validly authorized and issued, fully paid and nonassessable.

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

          (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from the
Chairman of the Board, the Chief Executive Officer, the President, any Vice
President, the Secretary, any Assistant 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 to
be taken by it in good faith in accordance with instructions of any such
officer.

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

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

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

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

          Section 21. CHANGE OF RIGHTS AGENT. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon thirty (30) days' notice in writing mailed to the Company, and to each
transfer agent of the Common Stock and Preferred Stock, by registered or
certified mail, and to the holders of the Rights Certificates by first-class
mail. The Company may remove the Rights Agent or any successor Rights Agent upon
thirty (30) days' notice in writing, mailed to the Rights Agent or successor
Rights Agent, as the case may be, and to each transfer agent of the Common Stock
and Preferred Stock, by registered or certified mail, and to the holders of the
Rights Certificates by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Company shall appoint
a successor to the Rights Agent. If the Company shall fail to make such
appointment within a period of thirty (30) days after giving notice of such
removal or after it has been notified in writing of such resignation or
incapacity by the resigning or incapacitated Rights Agent or by the holder of a
Rights Certificate (who shall, with such notice, submit his Rights Certificate
for inspection by the Company), then any registered holder of any Rights
Certificate may apply to any court of competent jurisdiction for the appointment
of a new Rights Agent. Any successor Rights Agent, whether appointed by the
Company or by such a court, shall be (A) a corporation organized and doing
business under the laws of the United States or of the State of New York (or of
any other state of the United States so long as such corporation is authorized
to do business as a banking institution in the State of New York), 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 $100,000,000 or (B) a 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 the Preferred Stock, and mail a
notice thereof in writing to the registered holders of the Rights Certificates.
Failure to give any notice provided for in this Section 21, however, or any
defect therein, shall not affect the legality or validity of the resignation or
removal of the Rights Agent or the appointment of the successor Rights Agent, as
the case may be.

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

          Section 23. REDEMPTION AND TERMINATION.

          (a) Subject to the provisions of Section 23(c) hereof, the Board of
Directors of the Company may, at its option, at any time prior to the earlier of
(i) the close of business on the tenth day following the Stock Acquisition Date
(or, if the Stock Acquisition Date shall have occurred prior to the Record Date,
the close of business on the tenth day following the Record Date), or (ii) the
Final Expiration Date, redeem all but not less than all the then outstanding
Rights at a redemption price of $0.01 per Right, as such amount may be
appropriately adjusted to reflect any stock split, stock dividend or similar
transaction occurring after the date hereof (such redemption price being
hereinafter referred to as the "Redemption Price"); provided, however, that any
redemption after the Stock Acquisition Date must be authorized by the Board
(and, until the expiration of the 180-day period referred to in Section 23(c)
hereof, with the concurrence of a majority of the Continuing Directors). The
Board of Directors may not redeem any Rights following a determination pursuant
to Section 11(a)(ii)(B) that any Person is an Adverse Person. Notwithstanding
anything contained in this Agreement to the contrary, the Rights shall not be
exercisable after the first occurrence of a Section 11(a)(ii) Event until such
time as the Company's right of redemption hereunder has expired. The Company
may, at its option, pay the Redemption Price in cash, shares of Common Stock
(based on the Current Market Price, as defined in Section 11(d)(i) hereof, of
the Common Stock at the time of redemption) or any other form of consideration
deemed appropriate by the Board of Directors.

          (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights, evidence of which shall have been
filed with the Rights Agent and without any further action and without any
notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price for
each Right so held. Promptly after the action of the Board of Directors ordering
the redemption of the Rights, the Company shall give notice of such redemption
to the Rights Agent and the holders of the then outstanding Rights by mailing
such notice to all such holders at each holder's last address as it appears upon
the registry books of the Rights Agent or, prior to the Distribution Date, on
the registry books of the transfer agent for the Common Stock. Any notice which
is mailed in the manner herein provided shall be deemed given, whether or not
the holder receives the notice. Each such notice of redemption will state the
method by which the payment of the Redemption Price will be made.

          (c) Notwithstanding the provisions of Section 23(a) hereof, in the
event that a majority of the Board is elected by stockholder action by written
consent, or is comprised of persons elected at a meeting of stockholders who
were not nominated by the Board in office immediately prior to such meeting or
action, then for a period of one hundred and eighty (180) days following the
effectiveness of such election the Rights shall not be redeemed if such
redemption is reasonably likely to have the purpose or effect of allowing any
Person to become an Acquiring Person or otherwise facilitating the occurrence of
a Triggering Event or a transaction with an Acquiring Person.

          Section 24. EXCHANGE.

          (a) The Board of Directors of the Company may, at its option, at any
time after any Person becomes an Acquiring Person or is determined to be an
Adverse Person pursuant to Section 11(a)(ii)(B), exchange all or part of the
then outstanding and exercisable Rights (which shall not include Rights that
have become void pursuant to the provisions of Section 7(e) hereof) for shares
of Common Stock at an exchange ratio of 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"). Notwithstanding the foregoing,
the Board of Directors shall not be empowered to effect such exchange at any
time after any Person (other than the Company, any Subsidiary of the Company,
any employee benefit plan of the Company or any such Subsidiary, or any entity
holding Common Stock for or pursuant to the terms of any such plan), together
with all Affiliates and Associates of such Person, becomes the Beneficial Owner
of fifty per cent (50%) or more of the Common Stock then outstanding.

          (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 equal
to the number of such Rights held by such holder multiplied by the Exchange
Ratio. The Company shall promptly give public notice of any such exchange;
PROVIDED, HOWEVER, that the failure to give, or any defect in, such notice shall
not affect the validity of such exchange. The Company promptly shall mail a
notice of any such exchange to all of the holders of such Rights at their last
addresses as they appear upon the registry books of the Rights Agent. Any notice
which is mailed in the manner herein provided shall be deemed given, whether or
not the holder receives the notice. Each such notice of exchange will state the
method by which the exchange of the Common Stock for Rights will be effected
and, in the event of any partial exchange, the number of Rights which will be
exchanged. Any partial exchange shall be effected pro rata based on the number
of Rights (other than Rights which have become void pursuant to the provisions
of Section 7(e) hereof) held by each holder of Rights.

          (c) In any exchange pursuant to this Section 24, the Company, at its
option, may substitute shares of Preferred Stock (or Equivalent Preferred Stock,
as such term is defined in paragraph (b) of Section 11 hereof) for shares of
Common Stock exchangeable for Rights, at the initial rate of one one-hundredth
(1/100th) of a share of Preferred Stock (or Equivalent Preferred Stock) for each
share of Common Stock, as appropriately adjusted to reflect adjustments in the
voting rights of the Preferred Stock pursuant to the terms thereof, so that the
fraction of a share of Preferred Stock delivered in lieu of each share of Common
Stock shall have the same voting rights as one share of Common Stock.

          (d) In the event that there shall not be sufficient shares of Common
Stock issued but not outstanding or authorized but unissued to permit any
exchange of Rights as contemplated in accordance with this Section 24, the
Company shall take all such action as may be necessary to authorize additional
shares of Common Stock for issuance upon exchange of the Rights.

          (e) 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, there shall be
paid to the registered holders of the Right Certificates 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 current market value of a whole share of
Common Stock. For the purposes of this subsection (e), the current market value
of a whole share of Common Stock shall be the closing price of a share of Common
Stock (as determined pursuant to the second sentence of Section 11(d)(i) hereof)
for the Trading Day immediately prior to the date of exchange pursuant to this
Section 24.

          Section 25. NOTICE OF CERTAIN EVENTS.

          (a) In case the Company shall propose, at any time after the
Distribution Date, (i) to pay any dividend payable in stock of any class to the
holders of Preferred Stock or to make any other distribution to the holders of
Preferred Stock (other than a regular quarterly cash dividend out of earnings or
retained earnings of the Company), or (ii) to offer to the holders of Preferred
Stock rights or warrants to subscribe for or to purchase any additional shares
of Preferred Stock or shares of stock of any class or any other securities,
rights or options, or (iii) to effect any reclassification of its Preferred
Stock (other than a reclassification involving only the subdivision of
outstanding shares of Preferred Stock), or (iv) to effect any consolidation or
merger into or with any other Person (other than a Subsidiary of the Company in
a transaction which complies with Section 11(o) hereof), or to effect any sale
or other transfer (or to permit one or more of its Subsidiaries to effect any
sale or other transfer), in one transaction or a series of related transactions,
of more than 50% of the assets or earning power of the Company and its
Subsidiaries (taken as a whole) to any other Person or Persons (other than the
Company and/or any of its Subsidiaries in one or more transactions each of which
complies with Section 11(o) hereof), or (v) to effect the liquidation,
dissolution or winding up of the Company, then, in each such case, the Company
shall give to each holder of a Rights Certificate, to the extent feasible and in
accordance with Section 26 hereof, a notice of such proposed action, which shall
specify the record date for the purposes of such stock dividend, distribution of
rights or warrants, or the date on which such reclassification, consolidation,
merger, sale, transfer, liquidation, dissolution, or winding up is to take place
and the date of participation therein by the holders of the shares of Preferred
Stock, if any such date is to be fixed, and such notice shall be so given in the
case of any action covered by clause (i) or (ii) above at least twenty (20) days
prior to the record date for determining holders of the shares of Preferred
Stock for purposes of such action, and in the case of any such other action, at
least twenty (20) days prior to the date of the taking of such proposed action
or the date of participation therein by the holders of the shares of Preferred
Stock whichever shall be the earlier.

          (b) In case any of the events set forth in Section 11(a)(ii) hereof
shall occur, then, in any such case, (i) the Company shall as soon as
practicable thereafter give to each holder of a Rights Certificate, to the
extent feasible and in accordance with Section 26 hereof, a notice of the
occurrence of such event, which shall specify the event and the consequences of
the event to holders of Rights under Section 11(a)(ii) hereof, and (ii) all
references in the preceding paragraph to Preferred Stock shall be deemed
thereafter to refer to Common Stock and/or, if appropriate, other securities.

          Section 26. NOTICES. Notices or demands authorized by this Agreement
to be given or made by the Rights Agent or by the holder of any 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 Agent) as follows:

         Stamford, Connecticut 06902
         Attention:  General Counsel

Subject to the provisions of Section 21, any notice or demand authorized by this
Agreement to be given or made by the Company or by the holder of any Rights

         Attn: Client Administration

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

          Section 27. SUPPLEMENTS AND AMENDMENTS. Prior to the Distribution Date
and subject to the provisions of this Section 27, the Company and the Rights
Agent shall, if the Company so directs, supplement or amend any provision of
this Agreement without the approval of any holders of certificates representing
shares of Common Stock. From and after the Distribution Date and subject to the
provisions of this Section 27, the Company and the Rights Agent shall, if the
Company so directs, supplement or amend this Agreement without the approval of
any holders of Rights Certificates in order (i) to cure any ambiguity, (ii) to
correct or supplement any provision contained herein which may be defective or
inconsistent with any other provisions herein, (iii) to shorten or lengthen any
time period hereunder or (iv) to change or supplement the provisions hereunder
in any manner which the Company may deem necessary or desirable and which shall
not adversely affect the interests of the holders of Rights Certificates (other
than an Acquiring Person or Adverse Person or an Affiliate or Associate of an
Acquiring Person or Adverse Person); PROVIDED, however, that any supplement or
amendment of this Agreement after the Stock Acquisition Date or after the date
on which the Board of Directors determines, pursuant to the criteria set forth
in Section 11(a)(ii)(B) hereof, that a Person is an Adverse Person, must be
approved by a majority of the Continuing Directors. Notwithstanding the
foregoing provisions of this Section 27, this Agreement may not be supplemented
or amended to lengthen, pursuant to clause (iii) of this sentence, (A) a time
period relating to when the Rights may be redeemed at such time as the Rights
are not then redeemable, or (B) any other time period unless such lengthening is
for the purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders of Rights (other than an Acquiring Person or Adverse
Person and its Affiliates and Associates). Upon the delivery of a certificate
from an appropriate officer of the Company which states that the proposed
supplement or amendment is in compliance with the terms of this Section 27, the
Rights Agent shall execute such supplement or amendment. Prior to the
Distribution Date, the interests of the holders of Rights shall be deemed
coincident with the interests of the holders of Common Stock.

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

          Section 29. DETERMINATIONS AND ACTIONS BY THE BOARD OF DIRECTORS, ETC.
For all purposes of this Agreement, any calculation of the number of shares of
Common Stock outstanding at any particular time, including for purposes of
determining the particular percentage of such outstanding shares of Common Stock
of which any Person is the Beneficial Owner, shall be made in accordance with
the last sentence of Rule 13d-3(d)(1)(i) of the General Rules and Regulations
under the Exchange Act. The Board of Directors (with, where specifically
provided for in this Agreement, the concurrence of the Continuing Directors) of
the Company shall have the exclusive power and authority to administer this
Agreement and to exercise all rights and powers specifically granted to the
Board (with, where specifically provided for in this Agreement, the concurrence
of the Continuing Directors) or to the Company, or as may be necessary or
advisable in the administration of this Agreement, including, without
limitation, the right and power to (i) interpret the provisions of this
Agreement, and (ii) make all determinations deemed necessary or advisable for
the administration of this Agreement (including, without limitation, a
determination to redeem or not redeem the Rights or to amend the Agreement). All
such actions, calculations, interpretations and determinations (including, for
purposes of clause (y) below, all omissions with respect to the foregoing) which
are done or made by the Board (with, where specifically provided for in this
Agreement, the concurrence of the Continuing Directors) in good faith, shall (x)
be final, conclusive and binding on the Company, the Rights Agent, the holders
of the Rights and all other parties, and (y) not subject the Board or any
Director to any liability to the holders of the Rights.

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

          Section 31. SEVERABILITY. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
PROVIDED, HOWEVER, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the close of business on the
tenth day following the date of such determination by the Board of Directors.
Without limiting the foregoing, if any provision requiring a majority of the
members of the Board of Directors to be Continuing Directors to act is held by
any court of competent jurisdiction or other authority to be invalid, void or
unenforceable, such determination shall be made by the Board of Directors of the
Company in accordance with applicable law and the Company's Certificate of
Incorporation and bylaws.

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

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

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

                                TOSCO CORPORATION


          The undersigned officers of Tosco Corporation, a corporation organized
and existing under the General Corporation Law of the State of Nevada (the
"Corporation"), in accordance with the provisions of Section 78.195 of the
Nevada Revised Statutes, DO HEREBY CERTIFY:

          That pursuant to the authority conferred upon the Board of Directors
by the Amended and Restated Articles of Incorporation of the said Corporation,
said Board of Directors at a meeting convened and held on November 19, 1998,
adopted the following resolution creating a series of 2,500,000 shares of
Preferred Stock designated as Series A Junior Participating Preferred Stock:

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

          Section 1. DESIGNATION AND AMOUNT. The shares of such series shall be
designated as "Series A Junior Participating Preferred Stock" and the number of
shares constituting such series shall be 2,500,000.

          Section 2. DIVIDENDS AND DISTRIBUTIONS.

                  (A) The holders of shares of Series A Junior Participating
          Preferred Stock shall be entitled to receive, when, as and if declared
          by the Board of Directors out of funds legally available for the
          purpose, quarterly dividends payable in cash on the last day of March,
          June, September and December in each year (each such date being
          referred to herein as a "Quarterly Dividend Payment Date"), commencing
          on the first Quarterly Dividend Payment Date after the first issuance
          of a share or fraction of a share of Series A Junior Participating
          Preferred Stock, in an amount per share (rounded to the nearest cent)
          equal to the greater of (a) $2.25 or (b) subject to the provision for
          adjustment hereinafter set forth, 100 times the aggregate per share
          amount of all cash dividends, and 100 times the aggregate per share
          amount (payable in kind) of all non-cash dividends or other
          distributions other than a dividend payable in shares of Common Stock
          or a subdivision of the outstanding shares of Common Stock (by
          reclassification or otherwise), declared on the Common Stock, par
          value $.75 per share, of the Corporation (the "Common Stock") since
          the immediately preceding Quarterly Dividend Payment Date, or, with
          respect to the first Quarterly Dividend Payment Date, since the first
          issuance of any share or fraction of a share of Series A Junior
          Participating Preferred Stock. In the event the Corporation shall at
          any time after November 19, 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 amount to which holders of shares of Series A
          Junior Participating Preferred Stock were entitled immediately prior
          to such event under clause (b) of the preceding sentence shall be
          adjusted by multiplying such amount by a fraction the numerator of
          which is the number of shares of Common Stock outstanding immediately
          after such event and the denominator of which is the number of shares
          of Common Stock that were outstanding immediately prior to such event.

                  (B) The Corporation shall declare a dividend or distribution
          on the Series A Junior Participating Preferred Stock as provided in
          Paragraph (A) above immediately after it declares a dividend or
          distribution on the Common Stock (other than a dividend payable in
          shares of Common Stock); PROVIDED that, in the event no dividend or
          distribution shall have been declared on the Common Stock during the
          period between any Quarterly Dividend Payment Date and the next
          subsequent Quarterly Dividend Payment Date, a dividend of $2.25 per
          share on the Series A Junior Participating Preferred Stock shall
          nevertheless be payable on such subsequent Quarterly Dividend Payment
          Date.

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

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

                  (A) Subject to the provision for adjustment hereinafter set
         forth, each share of Series A Junior Participating Preferred Stock
         shall entitle the holder thereof to 100 votes on all matters submitted
         to a vote of the stockholders of the Corporation. In the event the
         Corporation shall at any time after the Rights Declaration Date (i)
         declare any dividend on Common Stock payable in shares of Common Stock,
         (ii) subdivide the outstanding Common Stock, or (iii) combine the
         outstanding Common Stock into a smaller number of shares, then in each
         such case the number of votes per share to which holders of shares of
          Series A Junior Participating Preferred Stock were entitled
         immediately prior to such event shall be adjusted by multiplying such
         number by a fraction the numerator of which is the number of shares of
         Common Stock outstanding immediately after such event and the
         denominator of which is the number of shares of Common Stock that were
         outstanding immediately prior to such event.

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

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

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

                         (iii) Unless the holders of Preferred Stock shall,
               during an existing default period, have previously exercised
               their right to elect Directors, the Board of Directors may order,
               or any stockholder or stockholders owning in the aggregate not
               less than ten percent (10%) of the total number of shares of
               Preferred Stock outstanding, irrespective of series, may request,
               the calling of a special meeting of the holders of Preferred
               Stock, which meeting shall thereupon be called by the President,
               a Vice-President or the Secretary of the Corporation. Notice of
               such meeting and of any annual meeting at which holders of
               Preferred Stock are entitled to vote pursuant to this Paragraph
               (C)(iii) shall be given to each holder of record of Preferred
               Stock by mailing a copy of such notice to such holder at such
               holder's last address as the same appears on the books of the
               Corporation. Such meeting shall be called for a time not earlier
               than 10 days and not later than 50 days after such order or
               request or in default of the calling of such meeting within 50
               days after such order or request, such meeting may be called on
               similar notice by any stockholder or stockholders owning in the
               aggregate not less than ten percent (10%) of the total number of
               shares of Preferred Stock outstanding. Notwithstanding the
               provisions of this Paragraph (C)(iii), no such special meeting
               shall be called during the period within 50 days immediately
               preceding the date fixed for the next annual meeting of the
               stockholders.

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

                         (v) Immediately upon the expiration of a default
               period, (x) the right of the holders of Preferred Stock as a
               class to elect Directors shall cease, (y) the term of any
               Directors elected by the holders of Preferred Stock as a class
               shall terminate, and (z) the number of Directors shall be such
               number as may be provided for in the articles of incorporation or
               by-laws irrespective of any increase made pursuant to the
               provisions of Paragraph (C)(ii) of this Section 3 (such number
               being subject, however, to change thereafter in any manner
               provided by law or in the articles of incorporation or by-laws).
               Any vacancies in the Board of Directors effected by the
               provisions of clauses (y) and (z) in the preceding sentence may
               be filled by a majority of the remaining Directors.

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

         Section 4. CERTAIN RESTRICTIONS.

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

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

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

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

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

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

          Section 5. REACQUIRED SHARES. Any shares of Series A Junior
Participating Preferred Stock purchased or otherwise acquired by the Corporation
in any manner whatsoever shall be retired and cancelled promptly after the
acquisition thereof. All such shares shall upon their cancellation become
authorized but unissued shares of Preferred Stock and may be reissued as part of
a new series of Preferred Stock to be created by resolution or resolutions of
the Board of Directors, subject to the conditions and restrictions on issuance
set forth herein.

          Section 6. LIQUIDATION, DISSOLUTION OR WINDING UP. (A) Upon any
liquidation (voluntary or otherwise), dissolution or winding up of the
Corporation, no distribution shall be made to the holders of shares of stock
ranking junior (either as to dividends or upon liquidation, dissolution or
winding up) to the Series A Junior Participating Preferred Stock unless, prior
thereto, the holders of shares of Series A Junior Participating Preferred Stock
shall have received $90.00 per share, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series A Liquidation Preference"). Following the payment of
the full amount of the Series A Liquidation Preference, no additional
distributions shall be made to the holders of shares of Series A Junior
Participating Preferred Stock unless, prior thereto, the holders of shares of
Common Stock shall have received an amount per share (the "Common Adjustment")
equal to the quotient obtained by dividing (i) the Series A Liquidation
Preference by (ii) 100 (as appropriately adjusted as set forth in subparagraph
(C) below to reflect such events as stock splits, stock dividends and
recapitalizations with respect to the Common Stock) (such number in clause (ii),
the "Adjustment Number"). Following the payment of the full amount of the Series
A Liquidation Preference and the Common Adjustment in respect of all outstanding
shares of Series A Junior Participating Preferred Stock and Common Stock,
respectively, holders of Series A Junior Participating Preferred Stock and
holders of shares of Common Stock shall receive their ratable and proportionate
share of the remaining assets to be distributed in the ratio of the Adjustment
Number to 1 with respect to such Preferred Stock and Common Stock, on a per
share basis, respectively.

                  (B) In the event, however, that there are not sufficient
assets available to permit payment in full of the Series A Liquidation
Preference and the liquidation preferences of all other series of preferred
stock, if any, which rank on a parity with the Series A Junior Participating
Preferred Stock, then such remaining assets shall be distributed ratably to the
holders of such parity shares in proportion to their respective liquidation
preferences. In the event, however, that there are not sufficient assets
available to permit payment in full of the Common Adjustment, then such 
remaining assets shall be distributed ratably to the holders of  Common Stock.

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

          Section 7. CONSOLIDATION, MERGER, ETC. In case the Corporation shall
enter into any consolidation, merger, combination or other transaction in which
the shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case the shares of
Series A Junior Participating Preferred Stock shall at the same time be
similarly exchanged or changed in an amount per share (subject to the provision
for adjustment hereinafter set forth) equal to 100 times the aggregate amount of
stock, securities, cash and/or any other property (payable in kind), as the case
may be, into which or for which each share of Common Stock is changed or
exchanged. In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the amount set forth in the preceding sentence with respect to the exchange or
change of shares of Series A Junior Participating Preferred Stock shall be
adjusted by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event and
the denominator of which is the number of shares of Common Stock that were
outstanding immediately prior to such event.

          Section 8. NO REDEMPTION. The shares of Series A Junior Participating
Preferred Stock shall not be redeemable.

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

          Section 10. FRACTIONAL SHARES. Series A Junior Participating Preferred
Stock may be issued in fractions of a share which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of all
other rights of holders of Series A Junior Participating Preferred Stock.

upon the exercise of the Rights evidenced by this Rights Certificate are subject
to modification and adjustment upon the happening of certain events, including
Triggering Events.

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

          This Rights Certificate, with or without other Rights Certificates,
upon surrender at the principal office or offices of the Rights Agent designated
for such purpose, may be exchanged for another Rights Certificate or Rights
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number of one one-hundredths (1/100ths) of a share of
Preferred Stock as the Rights evidenced by the Rights Certificate or Rights
Certificates surrendered shall have entitled such holder to purchase. If this
Rights Certificate shall be exercised in part, the holder shall be entitled to
receive upon surrender hereof another Rights Certificate or Rights Certificates
for the number of whole Rights not exercised.

          Subject to the provisions of the Rights Agreement, the Rights
evidenced by this Certificate may be redeemed by the Company at its option at a
redemption price of $0.01 per Right at any time prior to the earlier of the
close of business on (i) the tenth day following the Stock Acquisition Date (as
such time period may be extended pursuant to the Rights Agreement), and (ii) the
Final Expiration Date. In addition, the Rights may be exchanged, in whole or in
part, for shares of the Common Stock, or shares of preferred stock of the
Company having essentially the same value or economic rights as such shares.
Immediately upon the action of the Board of Directors of the Company authorizing
any such exchange, and without any further action or any notice, the Rights
(other than Rights which are not subject to such exchange) will terminate and
the Rights will only enable holders to receive the shares issuable upon such
exchange.

          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-hundredth (1/100th) of a share of Preferred Stock,
which may, at the election of the Company, be evidenced by depositary receipts),
but in lieu thereof a cash payment will be made, as provided in the Rights
Agreement.

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