                                RIGHTS AGREEMENT

               This Rights Agreement, dated as of September 30, 2002 is entered
into between SCS TRANSPORTATION, INC., a Delaware corporation (the "Company")
and MELLON INVESTOR SERVICES LLC, a New Jersey limited liability company (the
"Rights Agent").

                               W I T N E S S E T H

               WHEREAS, on September 17, 2002, the Board of Directors of the
Company authorized and declared a dividend distribution of one right
(hereinafter referred to as a "Right") for each share of Common Stock, par value
$0.001 per share, of the Company outstanding at the close of business on
September 30, 2002 (the "Record Date"), (other than shares of such Common Stock
held in the Company's treasury on such date) and has authorized the issuance of
one Right in respect of each share of Common Stock of the Company issued between
the Record Date (whether originally issued or issued from the Company's
treasury) and the Distribution Date (as such term is defined in Section 3
hereof), each Right representing the right to purchase one one-ten-thousandth of
a share of Series A Junior Participating Preferred Stock of the Company having
the rights, powers and preferences set forth in the form of Certificate of
Designations attached hereto as Exhibit A, upon the terms and subject to the
conditions hereinafter set forth (the "Rights"); and

               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 Rights
Agreement, the following terms have the meanings indicated:

               (a) "Acquiring Person" shall mean any Person (as hereinafter
defined) who or which, together with all Affiliates (as hereinafter defined) and
Associates (as hereinafter defined) of such Person, without the Prior Written
Approval of the Company (as hereinafter defined), shall be the Beneficial Owner
(as hereinafter defined) of securities of the Company constituting 15% or more
of the Voting Power (as hereinafter defined) of the Company or was such a
Beneficial Owner at any time after the date hereof, whether or not such Person
continues to be the Beneficial Owner of securities representing 15% or more of
the Voting Power of the Company, but shall not include (i) the Company, any
Subsidiary of the Company, any employee benefit plan or compensation arrangement
of the Company or any Subsidiary of the Company, or any entity holding
securities of the Company to the extent organized, appointed or established by
the Company or any Subsidiary of the Company for or pursuant to the terms of any
such employee benefit plan or compensation arrangement, or prior to the Spin-off
Date, Yellow or (ii) any Person who or which, together with all Affiliates and
Associates of such Person, inadvertently may become the Beneficial Owner of
securities of the Company representing 15% or more of the Voting Power of the
Company or otherwise becomes such a Beneficial Owner without a plan or intention
to acquire control of the Company, so long as such Person,

<PAGE>
individually or together with the Affiliates and Associates of such Person,
promptly enters into, and delivers to the Company, an irrevocable commitment
promptly to divest, and thereafter promptly divests (without exercising or
retaining any power, including voting, with respect to such securities),
sufficient securities of the Company so that such Person, together with all
Affiliates and Associates of such Person, ceases to be the Beneficial Owner of
15% or more of the Voting Power of the Company. Notwithstanding the foregoing,
no Person shall become an "Acquiring Person" as the result of an acquisition of
voting securities of the Company by the Company which, by reducing the amount of
such securities outstanding, increases the proportionate voting power of such
securities beneficially owned by such Person to 15% or more of the Voting Power
of the Company; provided, however, that if a Person becomes the Beneficial Owner
of securities constituting 15% or more of the Voting Power of the Company by
reason of purchases by the Company and shall, after such purchases by the
Company, become the Beneficial Owner of any additional voting securities of the
Company without the Prior Written Approval of the Company, then such Person
shall be deemed to be an Acquiring Person.

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

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

                      (i) which such Person or any of such Person's Affiliates
        or Associates beneficially owns, directly or indirectly as determined
        pursuant to Rule 13d-3 of the General Rules and Regulations under the
        Exchange Act, as in effect on the date hereof;

                      (ii) which such Person or any of such Person's Affiliates
        or Associates has (A) the right to acquire (whether such right is
        exercisable immediately or only after the passage of time) pursuant to
        any agreement, arrangement or understanding (other than customary
        agreements with and between underwriters and selling group members with
        respect to a bona fide public offering of securities), or upon the
        exercise of conversion rights, exchange rights, rights (other than these
        Rights), warrants or options, or otherwise, provided, however, that a
        Person shall not be deemed the "Beneficial Owner" of securities tendered
        pursuant to a tender or exchange offer made by or on behalf of such
        Person or any of such Person's Affiliates or Associates until such
        tendered securities are accepted for payment or exchange; or (B) the
        right to vote pursuant to any agreement, arrangement or understanding,
        provided, however, that a Person shall not be deemed the "Beneficial
        Owner" of any security under this clause (B) if the agreement,
        arrangement or understanding to vote such security (1) arises solely
        from a revocable proxy or consent given in response to a public proxy or
        consent solicitation made pursuant to, and in accordance with, the
        applicable rules and regulations under the Exchange Act and (2) is not
        also then reportable by such person on Schedule 13D under the Exchange
        Act (or any comparable or successor report); or

                      (iii) which are beneficially owned, directly or
        indirectly, by any other Person with which such Person or any of such
        Person's Affiliates or Associates has any agreement, arrangement or
        understanding (other than customary agreements with and

                                       2
<PAGE>
        between underwriters and selling group members with respect to a bona
        fide public offering of securities) for the purpose of acquiring,
        holding, voting (except pursuant to a revocable proxy or consent as
        described in clause (B) of subparagraph (ii) of this paragraph (c)) or
        disposing of any securities of the Company.

mean the number of such securities then issued and outstanding together with the
number of such securities not then actually issued and outstanding which such

New York time, on such date; provided, however, that if such date is not a
Business Day it shall mean 5:00 P.M., New York time, on the next succeeding
Business Day.

               (g) "Common Stock" shall mean the Common Stock, par value $0.001
per share, of the Company, except that "Common Stock" when used with reference

interests.

               Section 3. Issue of Right Certificates.

               (a) Until the earlier of (i) the Close of Business on the tenth
Business Day after the Stock Acquisition Date or (ii) the Close of Business on
the tenth Business Day (or such later date as may be determined by action of the
Board of Directors but in no event later than the tenth Business Day after such
time as any Person becomes an Acquiring Person) 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 entity holding securities of the
Company to the extent organized, appointed or established by the Company or any

within the meaning of Rule 14d-2(a) of the General Rules and Regulations under
the Exchange Act, without the Prior Written Approval of the Company, which
tender or exchange offer would result in any Person becoming the Beneficial
Owner of Voting Power aggregating 15% or more of the outstanding Voting Power
(including any such date which is after the date of this Rights Agreement and
prior to the issuance of the Rights; the earlier of such dates being herein
referred to as the "Distribution Date"), (y) 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
Right Certificates) and not by separate Right Certificates, as more fully set
forth below, and (z) the Rights (and the right to receive certificates therefor)
will be transferable only in connection with the transfer of the underlying
shares of Common Stock, as more fully set forth below. As soon as practicable
after the Company has (i) notified the Rights Agent in writing of the occurrence
of the Distribution Date, (ii) provided the Rights Agent with specific written
instruction, and (iii) provided the Rights Agent with all other relevant
information which the Rights Agent may request, the Company shall prepare and
execute, and the Rights Agent shall countersign and 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

                                       5
<PAGE>
Date, at the address of such holder shown on the records of the Company, a right
certificate, in substantially the form of Exhibit B hereto (the "Right
Certificate"), evidencing one Right for each share of Common Stock so held,
subject to adjustment as provided herein. As of and after the Distribution Date,
the Rights will be evidenced solely by such Right Certificates. Until the Rights
Agent receives written notice of the Distribution Date from the Company, the
Rights Agent may presume conclusively for all purposes that the Distribution
Date has not occurred.

               (b) On the Record Date or as soon as practicable thereafter, the
Company will send a copy of a Summary of Rights to Purchase Preferred Stock, in
substantially the form of Exhibit C hereto (the "Summary of Rights"), by
first-class, postage prepaid mail, to each record holder of the Common Stock as
of the Close of Business on the Record Date, at the address of such holder shown
on the records of the Company. With respect to certificates for the Common Stock
outstanding as of the Record Date, until the Distribution Date (or the earlier
redemption, expiration or termination of the Rights), the Rights will be
evidenced by such certificates for the Common Stock registered in the names of
the holders of the Common Stock and the registered holders of the Common Stock
shall also be registered holders of the associated Rights. Until the
Distribution Date (or the earlier redemption, expiration or termination of the
Rights), the surrender for transfer of any of the certificates for the Common
Stock outstanding in respect of which Rights have been issued shall also
constitute the transfer of the Rights associated with the Common Stock
represented by such certificate.

               (c) Certificates for the Common Stock issued after the Record
Date but prior to the earlier of the Distribution Date or the redemption,
expiration or termination of the Rights shall be deemed also to be certificates
for Rights and shall have impressed, printed or written on, or otherwise affixed
to them a legend substantially to the following effect:

               This certificate also evidences and entitles the holder hereof to
               certain Rights as set forth in a Rights Agreement between SCS
               Transportation, Inc. (the "Company") and Mellon Investor Services
               LLC (or any successor thereto), as Rights Agent, as it may from
               time to time be supplemented or amended (the "Rights Agreement"),
               the terms of which are incorporated herein by reference and a
               copy of which is on file at the principal executive offices of
               the Company. Under certain circumstances, as set forth in the
               Rights Agreement, such Rights may expire or may be redeemed,
               exchanged or be evidenced by separate certificates and no longer
               be evidenced by this certificate. The Company will mail to the
               holder of this certificate a copy of the Rights Agreement without
               charge promptly after receipt of a written request therefor.
               Under certain circumstances, Rights issued to or held by
               Acquiring Persons or their Affiliates or Associates (as defined
               in the Rights Agreement) and any subsequent holder of such Rights
               may become null and void.

With respect to such certificates containing the foregoing legend, until the
Distribution Date (or the earlier redemption, expiration or termination of the
Rights), the Rights associated with the Common Stock represented by such
certificates shall be evidenced by such certificates alone, and the surrender
for transfer of any of such certificates shall also constitute the transfer of
the Rights associated with the Common Stock represented by such certificates.

                                       6
<PAGE>
               In the event that the Company purchases or acquires any Common
Stock after the Record Date but prior to the Distribution Date, any Rights
associated with such Common Stock shall be deemed canceled and retired so that
the Company shall not be entitled to exercise any Rights associated with shares
of Common Stock which are no longer outstanding.

               Section 4. Form of Right Certificates.

               (a) The Right Certificates (and the forms of election to purchase
shares and of assignment to be printed on the reverse thereof) shall be in
substantially the same form as Exhibit B hereto and may have such marks of
identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate (but which do not affect the
rights, duties or obligations of the Rights Agent as set forth in this
Agreement) and as are not inconsistent with the provisions of this Rights
Agreement, or as may be required to comply with any applicable law, rule or
regulation or with any rule or regulation of any stock exchange on which the
Rights may from time to time be listed, or to conform to customary usage.
Subject to the provisions of Section 11 and Section 22 hereof, the Right
Certificates, whenever issued, shall be dated as of the Record Date, and on
their face shall entitle the holders thereof to purchase such number of one
ten-thousandths of a share of Preferred Stock as shall be set forth therein at
the price per one ten-thousandth of a share as set forth therein (the "Purchase
Price"), but the number and identity of such shares and the Purchase Price shall
be and remain subject to adjustment as provided in Sections 11, 13 and 22
hereof.

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

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

                                       7
<PAGE>
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 Right Certificates shall be executed on behalf of the
Company by its Chairman, President and Chief Executive Officer, Chief Financial
Officer 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 any Assistant Secretary of the Company, either
manually or by facsimile signature. The Right Certificates shall be
countersigned manually or by facsimile signature by the Rights Agent or the
registrar or co-registrar for the Common Stock (the "Registrar") and shall not
be valid for any purpose unless so countersigned. In case any officer of the
Company whose manual or facsimile signature is affixed to the Right Certificates
shall cease to be such officer of the Company before countersignature by the
Rights Agent or the Registrar and issuance and delivery by the Company, such
Right Certificates, nevertheless, may be countersigned by the Rights Agent or
the Registrar, issued and delivered with the same force and effect as though the
person who signed such Right Certificates had not ceased to be such officer of
the Company. Any Right Certificate may be signed on behalf of the Company by any
person who, at the actual date of the execution of such Right Certificate, shall
be a proper officer of the Company to sign such Right Certificate, although at
the date of the execution of this Rights Agreement any such person was not such
an officer.

               (b) Following the Distribution Date and receipt by the Rights
Agent of (i) written notice of the Distribution Date pursuant to Section 3(a)
hereof, and (ii) all necessary information reasonably requested by the Rights
Agent pursuant to Section 3(a) hereof, the Rights Agent will keep or cause to be
kept, at its stockholder services office or such other office designated for
such purpose, books for registration and transfer of the Right Certificates
issued hereunder. Such books shall show the names and addresses of the
respective holders of the Right Certificates, the number of Rights evidenced on
its face by each of the Right Certificates, the certificate number of each of
the Right Certificates and the date of each of the Right Certificates.

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

               (a) Subject to the provisions of 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 (as such term is defined in Section
7(a) hereof), any Right Certificate or Right Certificates may be transferred,
split up, combined or exchanged for another Right Certificate or Right
Certificates, entitling the registered holder to purchase a like number of
shares of Preferred Stock as the Right Certificate or Right Certificates
surrendered then entitled such holder to purchase. Any registered holder
desiring to transfer, split up, combine or exchange any Right Certificate shall
make such request in writing delivered to the Rights Agent, and shall surrender
the Right Certificate or Right Certificates to be transferred, split up,
combined or exchanged at the office of the Rights Agent designated for such
purpose. Neither the Rights Agent nor the Company

                                       8
<PAGE>
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
properly 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 or
the Rights Agent shall reasonably request. Thereupon, the Rights Agent shall
countersign and deliver to the person entitled thereto a Right Certificate or
Right 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
Right Certificates. The Rights Agent shall have no duty or obligation to take
any action under any Section of this Agreement which requires the payment by a
Rights holder of applicable taxes and/or governmental charges unless and until
it is satisfied that all such taxes or applicable governmental charges have been
paid.

               (b) Upon receipt by the Company and the Rights Agent of evidence
reasonably satisfactory to them of the loss, theft, destruction or mutilation of
a Right 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 Right Certificate if
mutilated, the Company will make and deliver a new Right Certificate of like
tenor to the Rights Agent for countersignature and delivery to the registered
owner in lieu of the Right Certificate so lost, stolen, destroyed or mutilated.

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

               (a) The registered holder of any Right Certificate may exercise
the Rights evidenced thereby (except as otherwise provided herein) in whole or
in part at any time after the Distribution Date upon surrender of the Right
Certificate, with the form of election to purchase on the reverse side thereof
duly executed, to the Rights Agent at the stockholder services office of the
Rights Agent or such office designated for such purpose, together with payment
of the Purchase Price for each one ten-thousandth of a share of Preferred Stock
as to which the Rights are exercised, at or prior to the Close of Business on
the Expiration Date. The "Expiration Date", as used in this Rights Agreement,
shall be the earliest of (i) the Final Expiration Date (as defined below), (ii)
the time at which the Rights are redeemed as provided in Section 23 hereof, or
(iii) the time at which the Rights are exchanged as provided in Section 24
hereof. The "Final Expiration Date", as used in this Rights Agreement, shall be
September 30, 2012.

               (b) The Purchase Price for each one ten-thousandth of a share of
Preferred Stock pursuant to the exercise of a Right shall initially be $96.00,
shall be subject to adjustment from time to time as provided in Sections 11 and
13 hereof and shall be payable in lawful money of the United States of America
in accordance with paragraph (c) below.

               (c) Upon receipt of a Right Certificate, with the form of
election to purchase duly executed, accompanied by payment of the Purchase Price
for each one-ten-thousandth of a share of Preferred Stock to be purchased and an
amount equal to any applicable tax or charge required to be paid by the holder
of the Rights pursuant hereto in accordance with Section 9 hereof by certified
check, bank draft or money order payable to the order of the Company or the

                                       9
<PAGE>
Rights Agent, the Rights Agent shall, subject to Section 20(k) hereof, thereupon
promptly (i) either (A) requisition from any transfer agent of the shares of
Preferred Stock (or make available, if the Rights Agent is the transfer agent)
certificates for the number of shares of Preferred Stock to be purchased and the
Company hereby irrevocably authorizes any such transfer agent to comply with all
such requests, or (B) if the Company, in its sole discretion, shall have elected
to deposit the shares of Preferred Stock issuable upon exercise of the Rights
hereunder into a depositary, requisition from the depositary agent depositary
receipts representing such number of one ten-thousandths of a share of Preferred
Stock as are to be purchased (in which case certificates for the shares of
Preferred Stock represented by such receipts shall be deposited by the transfer
agent with the depositary agent) and the Company hereby directs such depositary
agent to comply with all such requests, (ii) promptly 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 Right Certificate, registered in such
name or names as may be designated by such holder, (iii) when appropriate,
requisition from the Company the amount of cash to be paid in lieu of issuance
of fractional shares in accordance with Section 14 hereof, (iv) after receipt of
any such cash, promptly deliver such cash to or upon the order of the registered
holder of such Right Certificate, (v) when appropriate, requisition from the
Company the amount of cash or securities issuable upon exercise of a Right
pursuant to the adjustment provisions of Section 11 or the exchange provisions
of Section 24, and (vi) after receipt of any such cash or securities, promptly
deliver such cash or securities to or upon the order of the registered holder of
such Right Certificate, of any such cash or securities.

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

               (e) Notwithstanding anything in this Rights Agreement to the
contrary, upon the first occurrence of a Section 11(b) Event or a Section 13
Event, any Rights beneficially owned by (i) an Acquiring Person or an Associate
or Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person
(or of any such Associate or Affiliate) which becomes a transferee after the
Acquiring Person becomes such, or (iii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) which becomes a transferee prior to or
concurrently with the Acquiring Person becoming such and which receives such
Rights pursuant to either (A) a transfer (whether or not for consideration) from
the Acquiring Person (or any such Associate or Affiliate) to holders of equity
interests in such Acquiring Person (or any such Associate or Affiliate) or to
any Person with whom such Acquiring Person (or such Associate or Affiliate) has
any continuing plan, agreement, arrangement or understanding regarding the
transferred Rights, shares of Company Common Stock or the Company or (B) a
transfer which a majority of the Board of Directors has determined to be part of
a plan, agreement, arrangement or understanding which has as a primary purpose
or effect the avoidance of this Section 7(e), shall be null and void without any
further action, and no holder of such Rights shall have any rights whatsoever
with respect to such Rights, whether under any provision of this Agreement or
otherwise. The Company shall use all reasonable efforts to notify the Rights
Agent when this Section 7(e) applies and to ensure that the provisions of this
Section 7(e) and Section 4(b) are complied with, but neither the Company nor the
Rights Agent shall have any liability to any holder of Rights or

                                       10
<PAGE>
any other Person as a result of its failure to make any determination under this
Section 7(e) or Section 4(b) with respect to an Acquiring Person or its
Affiliates, Associates or transferees hereunder.

               (f) Notwithstanding anything in this Rights 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 the certificate
contained in the appropriate form of election to purchase set forth on the
reverse side of the Right Certificate surrendered for such exercise shall have
been properly completed and duly executed by the registered holder thereof and
the Company or the Rights Agent shall have been provided with such additional
evidence of the identity of the Beneficial Owner (or former Beneficial Owner) or
Affiliates or Associates thereof as the Company or the Rights Agent shall
reasonably request.

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

               Section 9. Reservation and Availability of Shares of Preferred
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 or its authorized and issued shares of Preferred Stock held in
its treasury, the number of shares of Preferred Stock that will be sufficient to
permit the exercise in full of all outstanding Rights and, after the occurrence
of a Section 11(b) Event or a Section 13 Event, shall so reserve and keep
available a sufficient number of shares of Preferred Stock, Common Stock and/or
other securities which may be required to permit the exercise in full of the
Rights pursuant to this Rights Agreement.

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

               (c) The Company shall use its best efforts to (i) file, as soon
as practicable following the first occurrence of an event which would establish
the Distribution Date, a registration statement under the Securities Act, with
respect to the securities purchasable upon exercise of the Rights on an
appropriate form, (ii) cause such registration statement to become effective as
soon as practicable after such filing, and (iii) cause such registration
statement to

                                       11
<PAGE>
remain effective (with a prospectus at all times meeting the requirements of
the Securities Act) until the Expiration Date. The Company will also take such
action as may be appropriate under the "blue sky laws" of the various states.

               (d) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state taxes and governmental
charges which may be payable in respect of the issuance or delivery of the Right
Certificates or of any shares of Preferred Stock and/or other securities upon
the exercise of Rights. The Company shall not, however, be required to pay any
tax or charge which may be payable in respect of any transfer involved in the
transfer or delivery of Right Certificates or the issuance or delivery of
certificates or depositary receipts for Preferred Stock and/or other securities
in a name other than that of the registered holder of the Right Certificate
evidencing Rights surrendered for exercise, nor shall the Company be required to
issue or deliver any certificates or depositary receipts for shares of Preferred
Stock and/or other securities upon the exercise of any Rights until any such tax
or charge shall have been paid (any such tax or charge being payable by the
holder of such Right Certificate at the time of surrender) or until it has been
established to the Company's satisfaction that no such tax or charge is due.

               10. Preferred Stock Record Date. Each person (other than the
Company) in whose name any certificate for shares of Preferred Stock (or other
securities) is issued upon the exercise of Rights shall for all purposes be
deemed to have become the holder of record of the Preferred Stock (or other
securities) represented thereby on, and such certificate shall be dated, the
date upon which the Right Certificate evidencing such Rights was duly
surrendered and payment of the Purchase Price (and any applicable taxes or
charges) was made; provided, however, that if the date of such surrender and
payment is a date upon which the Preferred Stock (or other securities) transfer
books of the Company are closed, such person shall be deemed to have become the
record holder of such shares on, and such certificate shall be dated, the next
succeeding Business Day on which the Preferred Stock (or other securities)
transfer books of the Company are open. Prior to the exercise of the Rights
evidenced thereby, the holder of a Right 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 of Shares or
Number of Rights. The Purchase Price, the number and identity 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) In the event the Company shall at any time after the date of
this Rights Agreement (i) declare a dividend on the Preferred Stock payable in
shares of Preferred Stock, (ii) subdivide the outstanding Preferred Stock, (iii)
combine the outstanding Preferred Stock into a smaller number of shares or (iv)
issue any shares of its capital stock in a reclassification of the Preferred
Stock (including any such reclassification in connection with a consolidation or
merger in which the Company is the continuing or surviving corporation), except
as otherwise provided in this Section 11, the Purchase Price in effect at the
time of the record date for such dividend or

                                       12
<PAGE>
the time of the effective date of such subdivision, combination or
reclassification, and the number and kind of shares of capital stock, including
Preferred Stock, issuable upon exercise of a Right, shall be proportionately
adjusted so that the holder of any Right exercised after such time, upon payment
of the aggregate consideration such holder would have had to pay to exercise
such Right prior to such time, shall be entitled to receive the aggregate number
and kind of shares of capital stock, including Preferred Stock, which, if such
Right had been exercised immediately prior to such date and at a time when the
Preferred Stock transfer books of the Company were open, such holder would have
owned upon such exercise and been entitled to receive by virtue of such
dividend, subdivision, combination or reclassification.

               (b) In the event any Person becomes an Acquiring Person ("Section
11(b) Event"), then proper provision shall be made so that each holder of a
Right, subject to Section 7(e) and Section 24 hereof and except as provided
below, shall after the later of the occurrence of such event and the effective
date of an appropriate registration statement pursuant to Section 9 hereof, have
a right to receive, upon exercise thereof at the then current Purchase Price,
multiplied by the then number of one-ten-thousandths of a share of Preferred
Stock for which a Right is then exercisable, in accordance with the terms of
this Rights Agreement, in lieu of shares of Preferred Stock, such number of
shares of Common Stock of the Company as shall equal the result obtained by (y)
multiplying the then current Purchase Price by the then number of
one-ten-thousandths of a share of Preferred Stock for which a Right is then
exercisable and dividing that product by (z) 50% of the current market price per
one share of Common Stock (determined pursuant to Section 11(f) hereof on the
date of the occurrence of the Section 11(b) Event) (such number of shares being
referred to as the "number of Adjustment Shares").

               (c) In the event that there shall not be sufficient Treasury
shares or authorized but unissued shares of Common Stock to permit the exercise
in full of the Rights in accordance with the foregoing Section 11(b), and the
Rights become so exercisable, notwithstanding any other provision of this Rights
Agreement, to the extent necessary and permitted by applicable law and any
agreements in effect on the date hereof to which the Company is a party, each
Right shall thereafter represent the right to receive, upon exercise thereof at
the then current Purchase Price, multiplied by the then number of
one-ten-thousandths of a share of Preferred Stock for which a Right is then
exercisable, in accordance with the terms of this Rights Agreement, a number of
shares, or units of shares, of (y) Common Stock, and (z) preferred stock (or
other equity securities) of the Company, including, but not limited to Preferred
Stock, equal in the aggregate to the number of Adjustment Shares where the Board
of Directors shall have in good faith deemed such shares or units, other than
the shares of Common Stock, to have at least the same value and voting rights as
the Common Stock (a "common stock equivalent"); provided, however, if there are
unavailable sufficient shares (or fractions of shares) of Common Stock and/or
common stock equivalents, then the Company shall take all such action as may be
necessary to authorize additional shares of Common Stock or common stock
equivalents for issuance upon exercise of the Rights, including the calling of a
meeting of stockholders; and provided, further, that if the Company is unable to
cause sufficient shares of Common Stock and/or common stock equivalents to be
available for issuance upon exercise in full of the Rights, then the Company, to
the extent necessary and permitted by applicable law and any agreements or
instruments in effect on the date thereof to which it is a party, shall make
provision to pay an amount in cash equal to twice the Purchase Price (as
adjusted pursuant to this Section 11), in lieu of issuing shares of Common Stock
and/or common stock equivalents. To the extent that the

                                       13
<PAGE>
Company determines that some action needs to be taken pursuant to this Section
11(c), the Board of Directors by action of at least a majority of its members
then in office may suspend the exercisability of the Rights for a period of up
to sixty (60) days following the date on which the Section 11(b) Event shall
have occurred, in order to decide the appropriate form of distribution to be
made pursuant to this Section 11(c) 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
(with prompt written notice thereof to the Rights Agent). The Board of Directors
may, but shall not be required to, establish procedures to allocate the right to
receive Common Stock and common stock equivalents upon exercise of the Rights
among holders of Rights, which such allocation may be, but is not required to
be, pro rata.

               (d) If the Company shall fix a record date for the issuance of
rights or warrants to all holders of Preferred Stock entitling them (for a
period expiring within 90 calendar days after such record date) to subscribe for
or purchase Preferred Stock (or securities having the same or more favorable
rights, privileges and preferences as the 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 or exercise price per share, as the case
may be, less than the current market price per share of Preferred Stock (as
defined in Section 11(f) hereof) 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 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 or equivalent
preferred stock to be offered (and/or the aggregate initial conversion price of
the convertible securities so to be offered) would purchase at such current
market price, and the denominator of which shall be the number of shares of
Preferred Stock outstanding on such record date plus the number of additional
shares of Preferred Stock and/or equivalent preferred stock to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible). In case such subscription price may be paid
in a consideration, part or all of which shall be in a form other than cash, the
value of such consideration shall be as determined in good faith by a majority
of the Board of Directors, whose determination shall be described in a statement
filed with the Rights Agent. 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 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.

               (e) If the Company shall fix a record date for the making of a
distribution to all holders of Preferred Stock (including any such distribution
made in connection with a consolidation or merger in which the Company is the
continuing or surviving corporation) of evidences of indebtedness, cash (other
than a regular periodic cash dividend out of 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
convertible securities, subscription rights or warrants (excluding those
referred to in Section 11(d) 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

                                       14
<PAGE>
current market price for one share of Preferred Stock (as defined in Section
11(f) hereof) on such record date less the fair market value (as determined in
good faith by a majority of the Board of Directors, whose determination shall be
described in a statement filed with the Rights Agent) of the portion of the
assets or evidences of indebtedness so to be distributed or of such convertible
securities, subscription rights or warrants applicable to one share of Preferred
Stock, and the denominator of which shall be such current market price for one
share of Preferred Stock. Such adjustments shall be made successively whenever
such a record date is fixed; and in the event that such distribution is not so
made, the Purchase Price shall again be adjusted to be the Purchase Price which
would then be in effect if such record date had not been fixed.

                      (i) For the purpose of any computation hereunder, the
        "current market price" of any security (a "Security" for purposes of
        this Section 11(f)(i)) on any date shall be deemed to be the average of
        the daily closing prices per share of such Security for the 30
        consecutive Trading Days (as hereinafter defined) immediately prior to
        but not including such date; provided, however, that in the event that
        the current market price per share of such Security is determined during
        a period following the announcement by the issuer of such Security of
        (A) a dividend or distribution on such Security payable in shares of
        such Security or securities convertible into shares of such Security or
        (B) any subdivision, combination or reclassification of such Security,
        and prior to the expiration of 30 Trading Days after the ex-dividend
        date for such dividend or distribution or the record date for such
        subdivision, combination or reclassification, then, and in each such
        case, the "current market price" shall be appropriately adjusted to
        reflect the current market price per share equivalent of such Security.
        The closing price for each day shall be the last sale price, regular
        way, or, in case no such sale takes place on such day, the average of
        the closing bid and asked prices, regular way, in either case as
        reported in the principal consolidated transaction reporting system with
        respect to securities listed or admitted to trading on the New York
        Stock Exchange or, if the Security is not listed or admitted to trading
        on the New York Stock Exchange, as reported in the principal
        consolidated transaction reporting system with respect to securities
        listed or admitted to trading on the principal national securities
        exchange on which the Security is listed or admitted to trading or, if
        the Security is not listed or admitted to trading on any national
        securities exchange, as reported by the National Association of
        Securities Dealers, Inc. Automated Quotation System ("Nasdaq") National
        Market, or if the Security is not listed or admitted to trading on any
        national securities exchange or included in the Nasdaq National Market,
        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 Security is not quoted by any such organization,
        the average of the closing bid and asked prices as furnished by a
        professional market maker making a market in the Security selected by a
        majority of the Board of Directors. If on any such date no market maker
        is making a market in the Security, the fair value of such Security on
        such date as determined in good faith by a majority of the Board of
        Directors shall be used. The term "Trading Day" shall mean a day on
        which the principal national securities exchange on which the Security
        is listed or admitted to trading is open for the transaction of business
        or, if the Security is not listed or admitted to trading on any national
        securities exchange a day on which the Nasdaq National Market is open
        for the transaction of business or, if the Security is not listed or
        admitted to trading on any national securities exchange or included in
        the Nasdaq National Market, a Business Day. If the Security is not
        publicly

                                       15
<PAGE>
        held or not so listed or traded, "current market price" shall mean the
        fair value as determined in good faith by a majority of the Board of
        Directors, whose determination shall be described in a statement filed
        with the Rights Agent.

                      (ii) For the purpose of any computation hereunder, the
        "current market price" per share (or one ten-thousandth of a 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(f) (other
        than the last sentence thereof). If the current market price per share
        (or one ten-thousandth of a 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(f), the "current market price" per share of Preferred
        Stock shall be conclusively deemed to be an amount equal to 1,000 (as
        such number may be appropriately adjusted for such events as stock
        splits, stock dividends and recapitalizations with respect to the Common
        Stock occurring after the date of this Rights Agreement) multiplied by
        the current market price per share of the Common Stock and the "current
        market price" per one ten-thousandth of a share of Preferred Stock shall
        be equal to the current market price per share of the Common Stock (as
        appropriately adjusted). If neither the Common Stock nor the Preferred
        Stock is publicly held or so listed or traded, "current market price"
        per share shall mean the fair value per share as determined in good
        faith by the Board of Directors, whose determination shall be described
        in a statement filed with the Rights Agent and shall be conclusive for
        all purposes.

               (f) No adjustment in the Purchase Price shall be required unless
such adjustment would require an increase or decrease of at least 1% in the
Purchase Price; provided, however, that any adjustments which by reason of this
Section 11(g) 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, as the case may be. Notwithstanding the first sentence of this Section
11(g), any adjustment required by this Section 11 shall be made no later than
the earlier of (i) three years from the date of the transaction which mandates
such adjustment or (ii) the Expiration Date.

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

               (h) 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-ten-thousandths of a
share of Preferred Stock or other capital stock of the Company purchasable from
time to time hereunder upon exercise of the Rights, all subject to further
adjustment of the Purchase Price.

                                       16
<PAGE>
               (i) Unless the Company shall have exercised its election as
provided in Section 11(k) hereof, upon each adjustment of the Purchase Price as
a result of the calculations made in Section 11(d) and (e) hereof, 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 ten-thousandths of a share of Preferred Stock (calculated to the nearest
one-ten-thousandth) obtained by (i) multiplying (A) the number of
one-ten-thousandths of a share of Preferred Stock covered by a Right immediately
prior to the adjustment by (B) 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.

               (j) The Company may elect on or after the date of any adjustment
of the Purchase Price to adjust the number of Rights, in substitution for any
adjustment in the number of shares of Preferred Stock purchasable upon the
exercise of a Right. Each of the Rights outstanding after such adjustment of the
number of Rights shall be exercisable for the number of one-ten-thousandths of a
share of Preferred Stock for which such 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 (with
prompt written notice thereof to the Rights Agent), 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 Right Certificates have been issued,
shall be at least 10 days later than the date of the public announcement. If
Right Certificates have been issued, upon each adjustment of the number of
Rights pursuant to this Section 11(k), the Company shall, as promptly as
practicable, cause to be distributed to holders of record of Right Certificates
on such record date Right 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 Right
Certificates held by such holders prior to the date of adjustment, and upon
surrender thereof, if required by the Company, new Right Certificates evidencing
all the Rights to which such holders shall be entitled after such adjustment.
Right 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 Right Certificates on the record date specified in
the public announcement.

               (k) Irrespective of any adjustment or change in the Purchase
Price or the number of shares of Preferred Stock issuable upon the exercise of
the Rights, the Right Certificates theretofore and thereafter issued may
continue to express the Purchase Price and the number of shares which were
expressed in the initial Right Certificates issued hereunder.

               (l) Before taking any action that would cause an adjustment
reducing the Purchase Price below the then par value, if any, of the shares of
Common Stock or other securities and below one ten-thousandth of the then par
value, if any, of the Preferred Stock, issuable upon exercise of the Rights, the
Company shall take any corporate action which may, in

                                       17
<PAGE>
the opinion of its counsel, be necessary in order that the Company may validly
and legally issue fully paid and nonassessable shares of such Preferred Stock,
Common Stock or other securities at such adjusted Purchase Price. If upon any
exercise of the Rights, a holder is to receive a combination of Common Stock and
common stock equivalents, a portion of the consideration paid upon such
exercise, equal to at least the then par value of a share of Common Stock of the
Company, shall be allocated as the payment for each share of Common Stock of the
Company so received.

               (m) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuing to the holder of any Right exercised after such record date
the shares of Preferred Stock and other capital stock or securities of the
Company, if any, issuable upon such exercise over and above the shares 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 upon the occurrence of the event requiring
such adjustment.

               (n) 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 a majority of the Board of
Directors shall determine to be advisable in order that any (i) consolidation or
subdivision of the Preferred Stock, (ii) issuance wholly for cash of any
Preferred Stock at less than the then current market price, (iii) issuance
wholly for cash of Preferred Stock or securities which by their terms are
convertible into or exchangeable for Preferred Stock, (iv) stock dividends or
(v) issuance of rights, options or warrants referred to hereinabove in this
Section 11, hereafter made by the Company to the holders of its Preferred Stock,
shall not be taxable to such stockholders.

               (o) In the event that at any time after the date of this Rights
Agreement and prior to the Distribution Date, the Company shall (i) declare or
pay any dividend on the Common Stock payable in shares of Common Stock or (ii)
effect a subdivision, combination or consolidation of the Common Stock (by
reclassification or otherwise than by payment of dividends in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in any
such case (y) the number of one-ten-thousandths of a share of Preferred Stock
purchasable after such event upon proper exercise of each Right shall be
determined by multiplying the number of one-ten-thousandths of a share of
Preferred Stock so purchasable immediately prior to such event by a fraction,
the numerator of which is the number of shares of Common Stock outstanding
immediately before such event and the denominator of which is the number of
shares of Common Stock outstanding immediately after such event, and (z) each
share of Common Stock outstanding immediately after such event shall have issued
with respect to it that number of Rights which each share of Common Stock
outstanding immediately prior to such event had issued with respect to it. The
adjustments provided for in this Section 11(p) shall be made successively
whenever such a dividend is declared or paid or such a subdivision, combination
or consolidation is effected.

                                       18
<PAGE>
               (p) The Company covenants and agrees that it shall not, at any
time after the Distribution Date and so long as the Rights have not been
redeemed pursuant to Section 23 hereof or exchanged pursuant to Section 24
hereof, (i) consolidate with, (ii) merge with or into, or (iii) sell or
transfer, in one or more 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, if 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.

               (q) The Company covenants and agrees that, after the Stock
Acquisition Date, it will not, except as permitted by Sections 23 and 24 hereof,
take any action the purpose or effect of which is to diminish substantially or
otherwise eliminate the benefits intended to be afforded by the Rights.

               Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made or any event affecting the Rights or
their exercisability (including without limitation an event which causes Rights
to become null and void) occurs, as provided in Sections 11 or 13 hereof, the
Company shall (a) promptly prepare a certificate setting forth such adjustment,
and a brief statement of the facts and calculations 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)
include a brief summary thereof in a mailing to each holder of a Rights
Certificate in accordance with Section 26 hereof, or prior to the Distribution
Date, disclose a brief summary in a filing under the Exchange Act. The Rights
Agent shall be fully protected in relying on any such certificate and on any
adjustment therein contained and shall have no duty with respect to, and shall
not be deemed to have knowledge of such adjustment or event unless and until it
shall have received such certificate. The Rights Agent shall not be accountable
with respect to, and shall incur no liability as a result of, the validity or
value (or the kind or amount) of any Rights, Common Stock, Preferred Stock or of
any securities or property which may at any time be issued or delivered upon the
exercise of any Right or upon any adjustment pursuant to Section 11 hereof, and
it makes no representation with respect thereto.

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

               (a) In the event that, directly or indirectly, at any time after
a Person has become an Acquiring Person, (x) the Company shall consolidate with,
or merge with and into, any other Person (other than a Subsidiary of the
Company), (y) any Person (other than a Subsidiary of the Company) shall
consolidate with or merge with and into the Company, and the Company shall be
the continuing or surviving corporation of such merger and, in connection with
such merger, all or part of the Common Stock shall be changed into or exchanged
for stock or other securities of any other Person (or the Company) 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 or more
transactions, assets or earning power aggregating 50% or more of the assets or
earning power of the Company and its Subsidiaries (taken as a whole) to any
other Person other than to the Company or one or more of its wholly owned
Subsidiaries,

                                       19
<PAGE>
then, and in each such case, proper provision shall be made so that (i) each
holder of a Right, subject to Section 7(e) hereof, shall thereafter have the
right to receive, upon the exercise thereof at the then current Purchase Price
multiplied by the then number of one-ten-thousandths of a share of Preferred
Stock for which a Right is then exercisable (or if a Section 11(b) Event has
occurred prior to the first occurrence of a Section 13 Event, multiplying the
number of such one-ten-thousandths of a share for which a Right was exercisable
immediately prior to the first occurrence of a Section 11(b) Event by the
Purchase Price in effect immediately prior to such first occurrence) in
accordance with the terms of this Rights Agreement, in lieu of Preferred Stock,
such number of shares of freely tradable Common Stock of the Principal Party (as
hereinafter defined), free and clear of liens, rights of call or first refusal,
encumbrances or other adverse claims, as shall be equal to the result obtained
by (A) multiplying the then current Purchase Price by the number of
one-ten-thousandths of a share of Preferred Stock for which a Right is then
exercisable (or if a Section 11(b) Event has occurred prior to the first
occurrence of a Section 13 Event, multiplying the number of such
one-ten-thousandths of a share for which a Right was exercisable immediately
prior to the first occurrence of a Section 11(b) Event by the Purchase Price in
effect immediately prior to such first occurrence), and dividing that product by
(B) 50% of the current market price per share of the Common Stock of such
Principal Party (determined in the manner described in Section 11(f) hereof) on
the date of consummation of such consolidation, merger, sale or transfer; (ii)
the Principal Party shall thereafter be liable for, and shall assume, by virtue
of such consolidation, merger, sale or transfer, all the obligations and duties
of the Company pursuant to this Rights 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, except for the provisions of
11(b), shall apply to such Principal Party; and (iv) such Principal Party shall
take such steps (including, but not limited to, the authorization and
reservation of a sufficient number of shares of its Common Stock to permit
exercise of all outstanding Rights in accordance with this Section 13(a)) in
connection with such consummation as may be necessary to assure that the
provisions hereof shall thereafter be applicable, as nearly as reasonably may
be, in relation to the shares of its Common Stock thereafter deliverable upon
the exercise of the Rights.

               (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) hereof, 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, including the Company, that is the
        other party to the merger or consolidation; and

                      (ii) in the case of any transaction described in clause
        (z) of the first sentence of Section 13(a) hereof, the Person that is
        the party receiving the greatest portion of the assets or earning power
        transferred pursuant to such transaction or transactions; provided,
        however, that in any case described in clause (i) or (ii) in this
        Section 13(b), (x) if the Common Stock of such Person is not at such
        time and has not been continuously over the preceding 12 month period
        registered under Section 12 of the Exchange Act, and such Person is a
        direct or indirect Subsidiary or Affiliate of another Person, "Principal
        Party" shall refer to such other Person; (y) in case such Person is a
        Subsidiary, directly or indirectly, or Affiliate of more than one
        Person, the Common

                                       20
<PAGE>
        Stocks of all 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 (z) 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 (x) and (y)
        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 shares of its authorized 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 each Principal
Party and each other Person who may become a Principal Party as a result of such
consolidation, merger, sale or transfer shall have executed and delivered to the
Rights Agent a supplemental agreement providing for the terms set forth in
paragraphs (a) and (b) of this Section 13 and further providing that, as soon as
practicable after the date of any consolidation, merger, sale or transfer of
assets mentioned in paragraph (a) of this Section 13, the Principal Party will:

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

                      (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(b) Event, the Rights which have not theretofore been exercised shall
thereafter also become exercisable in the manner described in Section 13(a)
hereof.

               Section 14. Fractional Rights and Fractional Shares.

               (a) The Company shall not be required to issue fractions of
Rights or to distribute Right Certificates which evidence fractional Rights. In
lieu of such fractional Rights, there shall be paid to the registered holders of
the Right Certificates with regard to which such

                                       21
<PAGE>
fractional Rights would otherwise be issuable, an amount in cash equal to the
same fraction of the current market value of a whole Right. For the purposes of
this Section 14(a), the current market value of a whole Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date on
which such fractional Rights would have been otherwise issuable. The closing
price 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 or
admitted to trading 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, as reported by the
Nasdaq National Market or, if the Rights are not listed or admitted to trading
on any national securities exchange or included in the Nasdaq National Market,
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 a majority
of the Board of Directors. If on any such date no such market maker is making a
market in the Rights, the fair value of the Rights on such date as determined in
good faith by a majority of the Board of Directors 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 ten-thousandth of a share of Preferred Stock) upon exercise of the Rights or
to distribute certificates which evidence fractional shares of Preferred Stock
(other than fractions which are integral multiples of one ten-thousandth of a
share of Preferred Stock). Fractions of shares of Preferred Stock in integral
multiples of one ten-thousandth of a share of Preferred Stock may, at the
election of the Company, be evidenced by depositary receipts, pursuant to an
appropriate agreement between the Company and a depositary selected by it,
provided that such agreement shall provide that the holders of such depositary
receipts shall have all the rights, privileges and preferences to which they are
entitled as beneficial owners of the shares of Preferred Stock represented by
such depositary receipts. In lieu of fractional shares of Preferred Stock that
are not integral multiples of one ten-thousandth of a share of Preferred Stock,
the Company may pay to the registered holders of Right Certificates at the time
such Right Certificates are exercised as herein provided an amount in cash equal
to the same fraction of the current market value of one ten-thousandth of a
share of Preferred Stock. For purposes of this Section 14(b), the current market
value of one ten-thousandth of a share of Preferred Stock shall be one
ten-thousandth of the closing price of a share of Preferred Stock (as determined
pursuant to Section 11(f)(ii) hereof) for the Trading Day immediately prior to
the date of such exercise.

               (c) Following the occurrence of one of the transactions or events
specified in Section 11 hereof giving rise to the right to receive common stock
equivalents (other than Preferred Stock) or other securities upon the exercise
of a Right, the Company shall not be required to issue fractions of shares or
units of such common stock equivalents or other securities upon exercise of the
Rights or to distribute certificates which evidence fractional shares of such
common stock equivalents or other securities. In lieu of fractional shares or
units of such

                                       22
<PAGE>
common stock equivalents or other securities, the Company may pay to the
registered holders of Right Certificates at the time such Rights are exercised
as herein provided an amount in cash equal to the same fraction of the current
market value of a share or unit of such common stock equivalent or other
securities. For purposes of this Section 14(c), the current market value shall
be determined in the manner set forth in Section 11(f) hereof for the Trading
Day immediately prior to the date of such exercise and, if such common stock
equivalent is not traded, each such common stock equivalent shall have the value
of one ten-thousandth of a share of Preferred Stock.

               (d) Except as otherwise expressly provided in this Section 14,
the holder of a Right by the acceptance of the Right expressly waives such
holder's right to receive any fractional Rights or any fractional share upon
exercise of Rights.

               (e) Whenever a payment for fractional Rights or fractional shares
is to be made by the Rights Agent, the Company shall (i) promptly prepare and
deliver to the Rights Agent, a certificate setting forth in reasonable detail
the facts related to such payments and the prices and/or formulas utilized in
calculating such payments, and (ii) provide sufficient monies to the Rights
Agent in the form of fully collected funds to make such payments. The Rights
Agent shall be fully protected in relying upon such a certificate and shall have
no duty with respect to, and shall not be deemed to have knowledge of any
payment for fractional Rights or fractional shares under any Section of this
Agreement relating to the payment of fractional Rights or fractional shares
unless and until the Rights Agent shall have received such a certificate and
sufficient monies.

               Section 15. Rights of Action.

               (a) All rights of action in respect of this Rights Agreement,
except for rights of action given to the Rights Agent under Section 18 or
Section 20 hereof, are vested in the respective registered holders of the Right
Certificates (and, prior to the Distribution Date, the registered holders of
Common Stock); and any registered holder of any Right 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 Right Certificate (or, prior to the
Distribution Date, of the Common Stock), may, in such holder's own behalf and
for such holder's own benefit, enforce, and may institute and maintain any suit,
action or proceeding against the Company to enforce, or otherwise act in respect
of, such holder's right to exercise the Rights evidenced by such Right
Certificate in the manner provided in such Right Certificate and in this Rights
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 Rights Agreement
and will be entitled to specific performance of the obligations under, and
injunctive relief against actual or threatened violations of, the obligations of
any Person subject to this Rights Agreement. Holders of Rights shall be entitled
to recover the reasonable costs and expenses, including attorneys' fees,
incurred by them in any action to enforce the provisions of this Rights
Agreement.

               (b) 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

                                       23
<PAGE>
preliminary or permanent injunction or other order, judgment, decree or ruling
(whether interlocutory or final) issued by a court or by a governmental,
regulatory, self-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, that the Company must use all reasonable efforts
to have any such injunction, order, judgment, decree or ruling lifted or
otherwise overturned as soon as possible.

               Section 16. Agreement of Right 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 Right Certificates are
transferable only on the registry books of the Rights Agent if surrendered at
the stockholder services office of the Rights Agent or such office designated
for such purpose, duly endorsed or accompanied by a proper instrument of
transfer; and

               (c) the Company and the Rights Agent may deem and treat the
Person in whose name the Right Certificate (or, prior to the Distribution Date,
the associated Common Stock Certificate) is registered as the absolute owner
thereof and of the Rights evidenced thereby (notwithstanding any notations of
ownership or writing on the Right Certificate 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 shall be
affected by any notice to the contrary.

               Section 17. Right Certificate Holder Not Deemed a Stockholder. No
holder, as such, of any Right Certificate shall be entitled to vote, receive
dividends or be deemed for any purpose the holder of Preferred Stock, Common
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 Right Certificate be construed to confer upon the holder of any
Right 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 Right Certificate shall have been exercised in accordance with the
provisions hereof.

               Section 18. Concerning the Rights Agent.

               (a) The Company agrees to pay to the Rights Agent reasonable
compensation for all services rendered by it hereunder and, from time to time,
on demand of the Rights Agent, its reasonable expenses and counsel fees and
other disbursements incurred in the preparation, administration, delivery,
execution and amendment of this Agreement and the exercise and performance of
its duties hereunder. The Company also agrees to indemnify the Rights Agent

                                       24
<PAGE>
for, and to hold it harmless against, any loss, liability, damage, judgment,
fine, penalty, claim, demand, settlement , cost or expense (including, without
limitation, the reasonable fees and expenses of legal counsel) incurred without
gross negligence, bad faith or willful misconduct on the part of the Rights
Agent (which gross negligence, bad faith or willful misconduct must be
determined by a final, non-appealable order, judgment, decree or ruling of a
court of competent jurisdiction), for any action taken, suffered or omitted by
the Rights Agent in connection with the acceptance, exercise, performance or
administration of its duties under this Agreement, including, without
limitation, the costs and expenses of defending against any claim of liability
in the premises. The costs and expenses incurred by the Rights Agent in
enforcing this right of indemnification shall be paid by the Company. The
provisions of this Section 18 and Section 20 below shall survive the termination
of this Agreement, the exercise or expiration of the Rights and the resignation
or removal of the Rights Agent.

               (b) The Rights Agent shall be authorized and protected and shall
incur no liability for or in respect of any action taken, suffered or omitted by
it in connection with its administration of this Rights Agreement or the
exercise or performance of its duties hereunder, in reliance upon any Right
Certificate or certificate for Preferred Stock, Common Stock or for other
securities of the Company, instrument of assignment or transfer, power of
attorney, endorsement, affidavit, letter, notice, instruction, 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, or otherwise upon the advice of
counsel as set forth in Section 20 hereof. The Rights Agent shall not be deemed
to have knowledge of any event of which it was supposed to receive notice
thereof hereunder, and the Rights Agent shall be fully protected and shall incur
no liability for failing to take any action in connection therewith unless and
until it has received such notice.

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

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

               (b) In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered, the Rights Agent may adopt the countersignature
under its prior name and deliver Right Certificates

                                       25
<PAGE>
so countersigned; and in case at that time any of the Right Certificates shall
not have been countersigned, the Rights Agent may countersign such Right
Certificates either in its prior name or in its changed name; and in all such
cases such Right Certificates shall have the full force provided in the Right
Certificates and in this Rights Agreement.

               20. Duties of Rights Agent. The Rights Agent undertakes to
perform only the duties and obligations expressly imposed by this Rights
Agreement (and no implied duties or obligations) upon the following terms and
conditions, by all of which the Company and the holders of Right 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 or any employee of the Rights Agent) and the
advice or opinion of such counsel shall be full and complete authorization and
protection to the Rights Agent and the Rights Agent shall incur no liability for
or in respect of any action taken or omitted by it in the absence of gross
negligence, bad faith or willful misconduct and in accordance with such advice
or opinion.

               (b) Whenever in the performance of its duties under this Rights
Agreement the Rights Agent shall deem it necessary or desirable that any fact or
matter be proved or established by the Company prior to taking, omitting 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,
President and Chief Executive Officer, Chief Financial Officer or any Vice
President and by the Treasurer or any Assistant Treasurer or the Secretary or
any Assistant Secretary of the Company and delivered to the Rights Agent; and
such certificate shall be full and complete authorization and protection to the
Rights Agent, and the Rights Agent shall incur no liability for or in respect
of, any action taken, omitted or suffered by it in the absence of gross
negligence, bad faith or willful misconduct under the provisions of this Rights
Agreement in reliance upon such certificate.

               (c) The Rights Agent shall be liable hereunder to the Company and
any other Person only for its own gross negligence, bad faith or willful
misconduct (which gross negligence, bad faith or willful misconduct must be
determined by a final, non-appealable order, judgment, decree or ruling of a
court of competent jurisdiction). Anything to the contrary notwithstanding, in
no event shall the Rights Agent be liable for special, punitive, indirect,
consequential or incidental loss or damage of any kind whatsoever (including,
but not limited to, lost profits), even if the Rights Agent has been advised of
the likelihood of such loss or damage. Any and all liability of the Rights Agent
under this Agreement will be limited to the amount of fees paid by the Company
to the Rights Agent pursuant to this Agreement.

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

               (e) The Rights Agent shall not have any liability for or be under
any responsibility in respect of the validity of this Rights Agreement or the
execution and delivery

                                       26
<PAGE>
hereof (except the due execution hereof by the Rights Agent) or in respect of
the validity or execution of any Right Certificate (except its countersignature
thereof); nor shall it be responsible for any breach by the Company of any
covenant or condition contained in this Rights Agreement or in any Right
Certificate; nor shall it be responsible for any change in the exercisability of
the Rights (including the Rights becoming null and void hereunder) or for any
adjustment required under the provisions of Sections 11 or 13 hereof or
responsible for the manner, method or amount of any such adjustment or the
ascertaining of the existence of facts that would require any such adjustment
(except with respect to the exercise of Rights evidenced by Right Certificates
after actual notice to the Rights Agent of any such adjustment, upon which the
Rights Agent may rely); nor shall it by any act hereunder be deemed to make any
representation or warranty as to the authorization or reservation of any shares
of Preferred Stock or other securities to be issued pursuant to this Rights
Agreement or any Right Certificate or as to whether any shares of Preferred
Stock or other securities will, when issued, be validly authorized and issued,
fully paid and nonassessable.

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

               (g) The Rights Agent is hereby authorized and directed to accept
instructions with respect to the performance of its duties hereunder from any
one of the Chairman of the Board, the Chief Executive Officer, the President,
the Chief Financial Officer, any Vice President, the Secretary, any Assistant
Secretary, the Treasurer or any Assistant Treasurer of the Company, and to apply
to such officers for advice or instructions in connection with its duties and
such instructions shall be full authorization and protection to the Rights
Agent, and the Rights Agent shall not be liable for any action taken, omitted or
suffered to be taken by it in the absence of gross negligence, bad faith or
willful misconduct in accordance with instructions of any such officer or for
any delay in acting while waiting for those instructions. Any application by the
Rights Agent for written instructions from the Company may, at the option of the
Rights Agent, set forth in writing any action proposed to be taken, omitted or
suffered by the Rights Agent under this Rights Agreement and the date on and/or
after which such action shall be taken or such omission shall be effective. The
Rights Agent shall not be liable for any action taken or suffered by, or
omission of, the Rights Agent in accordance with a proposal included in any such
application on or after the date specified in such application (which date shall
not be less than ten (10) Business Days after the date on which any officer of
the Company actually receives such application, unless any such officer shall
have consented in writing to an earlier date) unless, prior to taking any such
action (or the effective date in the case of an omission), the Rights Agent
shall have received written instructions in response to such application
specifying the action to be taken, suffered or omitted.

               (h) The Rights Agent and any stockholder, director, officer,
employee, agent or representative or Affiliate 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 the Rights Agent under this Rights
Agreement. Nothing

                                       27
<PAGE>
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 that reasonable care was exercised in the
selection and continued employment thereof.

               (j) No provision of this Rights Agreement shall require the
Rights Agent to expend or risk its own funds or otherwise incur any financial
liability in the performance of any of its duties hereunder or in the exercise
of its rights if it believes that repayment of such funds or adequate
indemnification against such risk or financial 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, clause 2
and/or, in the case of the certificate attached to the form of election to
purchase, clause 3 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
Rights Agreement upon 30 days' notice in writing mailed to the Company and to
each transfer agent of the Common Stock or Preferred Stock known to the Rights
Agent by registered or certified mail, and to the holders of the Right
Certificates by first class mail. The Company may remove the Rights Agent or any
successor Rights Agent upon 30 days' notice in writing, mailed to the Rights
Agent or successor Rights Agent, 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 Right Certificates by first class mail or, prior to the
Distribution Date, through any filing made by the Company pursuant to the
Exchange Act. If the Rights Agent shall resign or be removed or shall otherwise
become incapable of acting, the Company shall appoint a successor to the Rights
Agent. If the Company shall fail to make such appointment within a period of 30
days after 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 Right Certificate (which holder shall, with such notice, submit
such holder's Right Certificate for inspection by the Company), then the
registered holder of any Right 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 or other entity organized and doing business under the laws of the
United States or of any state, in good standing, having an office in the States
of New York or Missouri, which is authorized under such laws to exercise
corporate trust or stock transfer powers and is subject to supervision or
examination by federal or state authority or (b) an affiliate of a corporation
or other entity 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

                                       28
<PAGE>
property at the time held by it hereunder, and execute and deliver any further
assurance, conveyance, act or deed necessary for the purpose. Not later than the
effective date of any such appointment the Company shall file notice thereof in
writing with the predecessor Rights Agent and each transfer agent of the Common
Stock and Preferred Stock, and mail a notice thereof in writing to the
registered holders of the Right Certificates or, prior to the Distribution Date,
through any filing made by the Company pursuant to the Securities Exchange Act
of 1934, as amended. Failure to give any notice provided for 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 Right Certificates.

               (a) Notwithstanding any of the provisions of this Rights
Agreement or of the Rights to the contrary, the Company may, at its option,
issue new Right Certificates evidencing Rights in such form as may be approved
by a majority of the Board of Directors then in office to reflect any adjustment
or change in the Purchase Price and the number or kind or class of shares of
stock or other securities or property purchasable under the Right Certificates
made in accordance with the provisions of this Rights Agreement.

               (b) In addition, in connection with the issuance or sale of
Common Stock following the Distribution Date and prior to the redemption,
exchange 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 benefit plan or arrangement, 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, issue Right Certificates representing the appropriate number of
Rights in connection with such issuance or sale; provided, however, that (i) no
such Right Certificates 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
Right Certificates would be issued, and (ii) no Right 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) A majority of the Board of Directors then in office may, at
its option, at any time prior to the earlier of (i) the Close of Business on the
Stock Acquisition Date or (ii) the Close of Business on the Final Expiration
Date, elect to redeem all but not less than all of the then outstanding Rights
at a redemption price of $0.01 per Right, as 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"). The redemption of the Rights by the Board of Directors may be made
effective at such time, on such basis and with such conditions as the Board of
Directors in its sole discretion may establish.

               (b) Immediately upon the action of a majority of the Board of
Directors then in office electing to redeem the Rights, evidence of which shall
be promptly filed with the Rights Agent, or, when appropriate, immediately upon
the time or satisfaction of such conditions as the

                                       29
<PAGE>
Board of Directors may have established, and without any further action and
without any notice, the right to exercise the Rights will terminate and the only
right thereafter of the holders of Rights shall be to receive the Redemption
Price. The Company shall promptly give public disclosure of any such redemption
(with prompt written notice thereof to the Rights Agent); provided, however,
that the failure to give, or any defect in, any such disclosure shall not affect
the validity of such redemption. Within 10 days after the action of the Board of
Directors ordering the redemption of the Rights, the Company shall give notice
of such redemption to the holders of the then outstanding Rights by mailing such
notice to all such holders at their last addresses as they appear upon the
registry books of the Rights Agent or, prior to the Distribution Date, on the
registry books of the Transfer Agent for the Common 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) Neither the Company nor any of its Affiliates or Associates
may redeem, acquire or purchase for value any Rights at any time in any manner
other than that specifically set forth in this Section 23 or in Section 24
hereof and other than in connection with the purchase of Common Stock prior to
the Distribution Date.

               Section 24. Exchange.

               (a) The Board of Directors may, at its option, at any time after
any Person becomes an Acquiring Person, exchange all or part of the then
outstanding and exercisable Rights (which shall not include Rights that have
become null and void pursuant to the provisions of Section 7(e) hereof) for
Common Stock at an exchange ratio of one share of Common Stock per Right,
appropriately adjusted to reflect adjustments in the number of Rights pursuant
to Section 11 of this Rights Agreement (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 or compensation arrangement of the Company or any such Subsidiary,
or any entity holding securities of the Company to the extent organized,
appointed or established by the Company or any such Subsidiary for or pursuant
to the terms of any such employee benefit plan or compensation arrangement),
together with all Affiliates and Associates of such Person, becomes the
Beneficial Owner of 50% or more of the Voting Power of the Company.

               (b) Immediately upon the action of the Board of Directors
ordering the exchange of any Rights pursuant to paragraph (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 promptly shall give public notice of any such exchange (with prompt
written notice thereof to the Rights Agent); provided, however, that the failure
to give, or any defect in, such notice shall not affect the validity of such
exchange. The Company 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

                                       30
<PAGE>
of exchange will state the method by which the exchange of 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 null and 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 Preferred Stock (or equivalent preferred stock, as
such term is defined in Section 11(d) hereof) for Common Stock exchangeable for
Rights, at the initial rate of one ten-thousandth 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 or Preferred Stock (or equivalent preferred 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 or
Preferred Stock (or equivalent preferred stock) for issuance upon exchange of
the Rights.

               (e) The Company shall not be required to issue fractions of
Common Stock or to distribute certificates which evidence fractional shares of
Common Stock. In lieu of such fractional shares of Common Stock, the Company
shall pay to the registered holders of 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 paragraph (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(f)(i) hereof) for the Trading Day immediately prior to the date of exchange
pursuant to this Section 24.

               Section 25. Notice of Proposed Actions.

               (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 the Preferred Stock or to make any other distribution to the holders
of the Preferred Stock (other than a regular periodic cash dividend out of
earnings or retained earnings of the Company), (ii) to offer to the holders of
the Preferred Stock rights or warrants to subscribe for or to purchase any
additional shares of Preferred Stock or shares of stock of any other class or
any other securities, rights or options, (iii) to effect any reclassification of
the Preferred Stock (other than a reclassification involving only the
subdivision of outstanding shares of Preferred Stock), (iv) to effect any
consolidation or merger into or with, or to effect any sale or other transfer
(or to permit one or more of its Subsidiaries to effect any sales or other
transfer), in one or more transactions, of 50% or more of the assets or earning
power of the Company and its Subsidiaries (taken as a whole) to, any other
Person, (v) to effect the liquidation, dissolution or winding up of the Company,
or (vi) to declare or pay any dividend on the Common Stock payable in Common
Stock or to effect a subdivision,

                                       31
<PAGE>
combination or consolidation of the Common Stock (by reclassification or
otherwise than by payment of dividends in Common Stock), then, in each such
case, the Company shall give to each holder of a Right, in accordance with
Section 26 hereof, a notice of such proposed action (with prompt written notice
thereof to the Rights Agent), 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 Common Stock and/or Preferred Stock,
if any such date is to be fixed. Such notice shall be so given in the case of
any action covered by clauses (i) or (ii) above at least ten days prior to the
record date for determining holders of the Preferred Stock for purposes of such
action, and in the case of any such other action, at least ten days prior to the
date of the taking of such proposed action or the date of participation therein
by the holders of Preferred Stock, whichever shall be the earlier. The failure
to give notice required by this Section 25 or any defect therein shall not
affect the legality or validity of the action taken by the Company or the vote
upon any such action.

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

in a writing by the Company or by the Company and such successor Rights Agent.
Without limiting the foregoing, the Company may at any time prior to such time

              CERTIFICATE OF DESIGNATION, PREFERENCES AND RIGHTS OF

                            SCS TRANSPORTATION, INC.

                        PURSUANT TO SECTION 151(G) OF THE
                GENERAL CORPORATION LAW OF THE STATE OF DELAWARE

We, Herbert A. Trucksess III, Chairman, President and Chief Executive Officer,
and James J. Bellinghausen, Vice President and Chief Financial Officer, of SCS
Transportation, Inc., a corporation organized and existing under the General
Corporation Law of the State of Delaware (the "Company"), in accordance with the
provisions of Section 151(g) thereof, DO HEREBY CERTIFY:

               That pursuant to the authority conferred upon the Board of
Directors by the Certificate of Incorporation, as amended, of the Company, the
said Board of Directors on September 17, 2002, adopted the following resolution
creating a series of Five Thousand (5,000) 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 the Company in accordance with the provisions of its Amended and
Restated Certificate of Incorporation, as amended, a series of Preferred Stock
of the Company be and it hereby is created, and that the designation and amount
thereof and the 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.

               There shall be a series of the Preferred Stock which shall be
designated as the "Series A Junior Participating Preferred Stock," par value
$0.001 per share, and the number of shares constituting such series shall be
5,000. Such number of shares may be increased or decreased by resolution of the
Board of Directors; provided, that no decrease shall reduce the number of shares
of Series A Junior Participating Preferred Stock to a number less than that of
the shares then outstanding plus the number of shares issuable upon exercise of
outstanding rights, options or warrants or upon conversion of outstanding
securities issued by the Company.

               Section 2. Dividends and Distributions.

               (A) Subject to the rights of the holders of any shares of any
series of preferred stock of the Company ranking prior and superior to the
Series A Junior Participating Preferred Stock with respect to dividends, the
holders of shares of Series A Junior Participating Preferred Stock, in
preference to the holders of shares of Common Stock, par value $0.001 per share
of the Company (the "Common Stock"), and of any other junior stock, shall be
entitled to receive, when, as and if declared by the Board of Directors out of
funds legally available for the purpose,

<PAGE>
quarterly dividends payable in cash on any regular quarterly dividend payment
date as shall be established by the Board of Directors (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) $1.00
or (b) subject to the provision for adjustment hereinafter set forth, 10,000
times the aggregate per share amount of all cash dividends, and 10,000 times the
aggregate per share amount (payable in kind) of all non-cash dividends or other
distributions, other than a dividend payable in shares of Common Stock or a
subdivision of the outstanding shares of Common Stock (by reclassification or
otherwise), declared on the Common Stock since the immediately preceding
Quarterly Dividend Payment Date or, with respect to the first Quarterly Dividend
Payment Date, since the first issuance of any share or fraction of a share of
Series A Junior Participating Preferred Stock. In the event the Company shall at
any time after September 30, 2002 (the "Rights Declaration Date") declare or pay
any dividend on the Common Stock payable in shares of Common Stock, or effect a
subdivision or combination or consolidation of the outstanding shares of Common
Stock (by reclassification or otherwise than by payment of a dividend in shares
of Common Stock) into a greater or lesser number of shares of Common Stock, 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 Company shall declare a dividend or distribution on the
Series A Junior Participating Preferred Stock as provided in paragraph (A) of
this Section 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 $1.00 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,
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, in accordance with
applicable law, 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

                                       2
<PAGE>
thereon, which record date shall be not more than such number of days prior to
the date fixed for the payment thereof as may be allowed by applicable law.

               Section 3. Voting Rights.

               The holders of shares of Series A Junior Participating Preferred
Stock shall have the following voting rights:

               (A) Each share of Series A Junior Participating Preferred Stock
shall entitle the holder thereof to 10,000 votes on all matters submitted to a
vote of the stockholders of the Company. In the event the Company shall at any
time after the Rights Declaration Date declare or pay any dividend on the Common
Stock payable in shares of Common Stock, or effect a subdivision or combination
or consolidation of the outstanding shares of Common Stock (by reclassification
or otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
number of votes to which holders of shares of Series A Junior Participating
Preferred Stock were entitled immediately prior to such event under the
preceding sentence shall be adjusted by multiplying such amount by a fraction,
the numerator of which is the number of shares of Common Stock outstanding
immediately after such event and the denominator of which is the number of
shares of Common Stock that were outstanding immediately prior to such event.

               (B) Except as otherwise provided herein, in the Company's
Certificate of Incorporation or by law, the holders of shares of Series A Junior
Participating Preferred Stock, the holders of shares of Common Stock, and the
holders of shares of any other capital stock of the Company having general
voting rights, shall vote together as one class on all matters submitted to a
vote of stockholders of the Company.

               (C) Except as otherwise set forth herein or in the Company's
Certificate of Incorporation, and except as otherwise provided by law, 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 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 Company 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

                                       3
<PAGE>
        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) except as permitted in Section 4(A)(iv) below,
        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 Company may at any time redeem,
        purchase or otherwise acquire shares of any such parity stock in
        exchange for shares of any stock of the Company ranking junior (either
        as to dividends or upon dissolution, liquidation or winding up) to the
        Series A Junior Participating Preferred Stock; and

                      (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 Company shall not permit any subsidiary of the Company to
purchase or otherwise acquire for consideration any shares of stock of the
Company unless the Company 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 Company in any manner whatsoever shall be
retired and canceled promptly after the acquisition thereof. The Company shall
cause all such shares upon their cancellation to be authorized but unissued
shares of Preferred Stock which may be reissued as part of a new series of
Preferred Stock, subject to the conditions and restrictions on issuance set
forth herein.

               Section 6. Liquidation, Dissolution or Winding Up.

               (A) Subject to the rights of the holders of any shares of any
series of Preferred Stock of the Company ranking prior and superior to the
Series A Junior Participating Preferred Stock with respect to liquidation, upon
any liquidation (voluntary or otherwise), dissolution or winding up of the
Company, 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 $10,000.00 per share, plus an amount equal to accrued and unpaid
dividends and distributions thereon, whether or not declared, to the date of
such payment (the "Series A Liquidation Preference"). Following the payment of
the full

                                       4
<PAGE>
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) 10,000 (as
appropriately adjusted as set forth in subparagraph C below to reflect such
events as stock dividends, and subdivisions, combinations and consolidations
with respect to the Common Stock) (such number in clause (ii) being referred to
as 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 Series A Junior Participating
Preferred Stock and Common Stock, on a per share basis, respectively.

               (B) In the event 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
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 Company shall at any time after the Rights
Declaration Date declare or pay any dividend on Common Stock payable in shares
of Common Stock, or effect a subdivision or combination or consolidation of the
outstanding shares of Common Stock (by reclassification or otherwise than by
payment of a dividend in shares of Common Stock) into a greater or lesser number
of shares of Common Stock, 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 Company 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 10,000 times the aggregate amount of stock, securities, cash and/or any
other property (payable in kind), as the case may be, into which or for which
each share of Common Stock is changed or exchanged. In the event the Company
shall at any time after the Rights Declaration Date declare or pay any dividend
on Common Stock payable in shares of Common Stock, or effect a subdivision or
combination or consolidation of the outstanding shares of Common Stock (by
reclassification or otherwise than by payment of a dividend in shares of Common
Stock) into a greater or lesser number of shares of Common Stock, then in each
such case the amount set forth

                                       5
<PAGE>
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 are outstanding immediately
prior to such event.

               Section 8. Redemption.

               The shares of Series A Junior Participating Preferred Stock shall
not be redeemable.

               Section 9. Ranking.

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

               Section 10. 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."

Right Certificate are subject to modification and adjustment upon the happening
of certain events as provided in the Rights Agreement.

               This Right 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

               This Right Certificate, with or without other Right Certificates,
upon surrender at the stockholder services office (or such office designated for
such purpose) of the Rights Agent, may be exchanged for another Right
Certificate or Right Certificates of like tenor and date evidencing Rights

Certificate shall be exercised in part, the holder shall be entitled to receive,

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

                            SCS TRANSPORTATION, INC.

                           SUMMARY OF PREFERRED STOCK
                                 PURCHASE RIGHTS

               On September 17, 2002, the Board of Directors of SCS
Transportation, Inc. (the "Company") declared a dividend of one preferred share
purchase right (a "Right") for each outstanding share of Common Stock, par value
$0.001 per share, of the Company (the "Common Stock"). The dividend distribution
is payable on September 30, 2002 (the "Record Date") to the stockholders of
record at the close of business on that date. Each Right entitles the registered
holder to purchase from the Company one ten-thousandth of a share of Series A
Junior Participating Preferred Stock, par value $0.001 per share (the "Preferred
Stock") of the Company at a price of $96 per one ten-thousandth of a share of
Preferred Stock (the "Purchase Price"), subject to adjustment. The description
and terms of the Rights are set forth in a Rights Agreement dated as of
September 30, 2002, as the same may be amended from time to time (the "Rights
Agreement"), between the Company and Mellon Investor Services LLC, as Rights
Agent (the "Rights Agent").

               Until the earlier to occur of (i) the close of business on the
tenth business day following the date of public announcement or the date on
which the Company first has notice or determines that a person or group of
affiliated or associated persons (other than the Company, any subsidiary of the
Company or any employee benefit plan of the Company) (an "Acquiring Person") has
acquired, or obtained the right to acquire, 15% or more of the outstanding
shares of voting stock of the Company without the prior express written consent
of the Company executed on behalf of the Company by a duly authorized officer of
the Company following express approval by action of at least a majority of the
members of the Board of Directors then in office (the "Stock Acquisition Date")
or (ii) the close of business on the tenth business day (or such later date as
may be determined by action of the Board of Directors but not later than the
Stock Acquisition Date) following the commencement of a tender offer or exchange
offer, without the prior written consent of the Company, by a person (other than
the Company, any subsidiary of the Company or an employee benefit plan of the
Company) which, upon consummation, would result in such party's control of 15%
or more of the Company's voting stock (the earlier of the dates in clause (i) or
(ii) above being called the "Distribution Date"), the Rights will be evidenced,
with respect to any of the Common Stock certificates outstanding as of the
Record Date, by such Common Stock certificates.

               The Rights Agreement provides that, until the Distribution Date
(or earlier redemption or expiration of the Rights), the Rights will be
transferred with and only with the Company's Common Stock. Until the
Distribution Date (or earlier redemption, exchange or expiration of the Rights),
new Common Stock certificates issued after the Record Date upon transfer or new
issuances of Common Stock will contain a notation incorporating the Rights
Agreement by reference. Until the Distribution Date (or earlier redemption,
exchange or expiration of the Rights), the surrender for transfer of any
certificates for shares of Common Stock outstanding as of the Record Date, even
without such notation or a copy of this Summary of Rights, will also constitute
the transfer of the Rights associated with the Common Stock

<PAGE>
represented by such certificate. As soon as practicable following the
Distribution Date, separate certificates evidencing the Rights ("Right
Certificates") will be mailed to holders of record of the Common Stock as of the
close of business on the Distribution Date and such separate certificates alone
will then evidence the Rights.

               The Rights are not exercisable until the Distribution Date. The
Rights will expire, if not previously exercised, on September 30, 2012 (the
"Final Expiration Date"), unless the Final Expiration Date is extended or unless
the Rights are earlier redeemed or exchanged by the Company.

               The Purchase Price payable, and the number 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) upon the grant to holders of the Preferred Stock of
certain rights or warrants to subscribe for or purchase Preferred Stock at a
price, or securities convertible into Preferred Stock with a conversion price,
less than the then-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 periodic cash dividends or dividends payable in
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).

               The number of outstanding Rights and the number of one
ten-thousandths of a share of Preferred Stock issuable upon exercise of each
Right are also subject to adjustment in the event of a stock split of the Common
Stock or a stock dividend on the Common Stock payable in shares of Common Stock
or subdivisions, consolidations or combinations of the Common Stock occurring,
in any such case, prior to the Distribution Date.

               Shares of Preferred Stock purchasable upon exercise of the Rights
will not be redeemable and junior to any other series of preferred stock the
Company may issue (unless otherwise provided in the terms of such stock). Each
share of Preferred Stock will have a preferential dividend in an amount equal to
10,000 times any dividend declared on each share of Common Stock. In the event
of liquidation, the holders of the Preferred Stock will receive a preferred
liquidation payment of equal to the greater of $10,000 and 10,000 times the
payment made per share of Common Stock. Each share of Preferred Stock will have
10,000 votes, voting together with the Common Stock. In the event of any merger,
consolidation or other transaction in which shares of Common Stock are converted
or exchanged, each share of Preferred Stock will be entitled to receive 10,000
times the amount and type of consideration received per share of Common Stock.
The rights of the Preferred Stock as to dividends, liquidation and voting, and
in the event of mergers and consolidations, are protected by customary
antidilution provisions.

               Because of the nature of the Preferred Stock's dividend,
liquidation and voting rights, the value of the one ten-thousandth interest in a
share of Preferred Stock purchasable upon exercise of each Right should
approximate the value of one share of Common Stock.

               If any person or group (other than the Company, any subsidiary of
the Company or any employee benefit plan of the Company) acquires 15% or more of
the Company's outstanding voting stock without the prior written consent of the
Board of Directors, each Right, except those held by such persons, would entitle
each holder of a Right to acquire such number

                                       2
<PAGE>
of shares of the Company's Common Stock as shall equal the result obtained by
multiplying the then current Purchase Price by the number of one-ten-thousandths
of a share of Preferred Stock for which a Right is then exercisable and dividing
that product by 50% of the then current per share market price of Company Common
Stock.

               If any person or group (other than the Company, any subsidiary of
the Company or any employee benefit plan of the Company) acquires more than 15%
but less than 50% of the outstanding Company Common Stock without prior written
consent of the Board of Directors, each Right, except those held by such
persons, may be exchanged by the Board of Directors for one share of Company
Common Stock.

               If the Company were acquired in a merger or other business
combination transaction where the Company is not the surviving corporation or
where Company Common Stock is exchanged or changed or 50% or more of the
Company's assets or earnings power is sold in one or several transactions
without the prior written consent of the Board of Directors, each Right would
entitle the holders thereof (except for the Acquiring Person) to receive such
number of shares of the acquiring company's common stock as shall be equal to
the result obtained by multiplying the then current Purchase Price by the number
one-ten-thousandths of a share of Preferred Stock for which a Right is then
exercisable and dividing that product by 50% of the then current market price
per share of the common stock of the acquiring company on the date of such
merger or other business combination transaction.

               With certain exceptions, no adjustment in the Purchase Price will
be required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional shares of Preferred Stock will be issued
(other than fractions which are integral multiples of one ten-thousandth of a
share of Preferred Stock, which may, at the election of the Company, be
evidenced by depositary receipts), and in lieu thereof an adjustment in cash
will be made based on the market price of the Preferred Stock on the last
trading day prior to the date of exercise.

               At any time prior to the time an Acquiring Person becomes such,
the Board of Directors of the Company may redeem the Rights in whole, but not in
part, at a price of $0.01 per Right (the "Redemption Price"). The redemption of
the Rights may be made effective at such time, on such basis and with such
conditions as the Board of Directors in its sole discretion may establish.
Immediately upon any redemption of the Rights, the right to exercise the Rights
will terminate and the only right of the holders of Rights will be to receive
the Redemption Price.

               The terms of the Rights may be amended by the Board of Directors
of the Company without the consent of the holders of the Rights, including, but
not limited to, an amendment to lower certain thresholds described above to not
less than the greater of (i) any percentage greater than the largest percentage
of the voting power of all securities of the Company then known to the Company
to be beneficially owned by any person or group of affiliated or associated
persons (other than an excepted person) and (ii) 10%, except that from and after
such time as any person or group of affiliated or associated persons becomes an
Acquiring Person no such amendment may adversely affect the interests of the
holders of the Rights.

                                       3
<PAGE>
               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.

               A copy of the Rights Agreement has been filed with the Securities
and Exchange Commission as an Exhibit to a Registration Statement on Form 10
dated September 6, 2002. A copy of the Rights Agreement is available free of
charge from the Company. This summary description of the Rights does not purport
to be complete and is qualified in its entirety by reference to the Rights
Agreement, as the same may be amended from time to time, which is hereby
incorporated herein by reference.

Capitalized terms used herein and not otherwise defined shall have the meanings
assigned to them in Article VII hereof.

        A.     WHEREAS, Yellow is the sole stockholder of SCST, and SCST is the
               sole stockholder of the operating subsidiaries Saia Motor Freight
               Line, Inc. ("Saia") and Jevic Transportation, Inc. ("Jevic");

        B.     WHEREAS, Yellow's Board of Directors has determined pursuant to
               an integrated plan to (i) separate SCST, which comprises Yellow's
               non-union, regional operations, from Yellow's other businesses
               and operations (the "Separation") and (ii) distribute to Yellow's
               stockholders on a tax-free basis all of the outstanding shares of
               SCST's common stock (the "Distribution");

        C.     WHEREAS, Yellow's Board of Directors has determined that it is in
               the best interests of its stockholders to consummate the
               Separation and the Distribution;

        D.     WHEREAS, it is appropriate and desirable to set forth the
               principal corporate transactions required to effect the
               Separation and the Distribution and certain other agreements that
               will govern certain matters relating to such transactions
               (collectively, the "Transactions") and the relationship of Yellow
               and SCST following the consummation of the Transactions;

NOW, THEREFORE, the parties, intending to be legally bound, agree as follows:

                              TERMS AND CONDITIONS

        In consideration of the mutual covenants herein, and other good and
valuable consideration, the receipt and adequacy of which are hereby

reasonable steps necessary and appropriate to cause all conditions to the
Distribution to be satisfied and to effect the Distribution. Yellow's Board of
Directors will have the sole discretion to determine the Distribution Date, and

the transfer agent for the Yellow Common Stock to instruct the Distribution
Agent to distribute on the Distribution Date the appropriate number of such
shares of SCST Common Stock to each such holder or designated transferee or
transferees of such holder.

             (iii) Subject to Section 1.3 hereof, each holder of record of
Yellow Common Stock (or such holder's designated transferee or transferees) on
the Record Date will be entitled to receive in the Distribution that number of
shares of SCST Common Stock equal to that number of shares of Yellow Common
Stock owned by such holder on the Record Date divided by a number equal to the
Distribution Ratio established by Yellow's Board of Directors.

                               any time prior to the Record Date;

                       (x)     Yellow's Board of Directors shall be satisfied
                               that the Distribution does not constitute the
                               conveyance of all or substantially all of the
                               properties or assets of Yellow immediately prior
                               to the Distribution, as contemplated in Section
                               271 of the Delaware General Corporation Law;

                       (xi)    the Certificate of Incorporation and By-laws
                               shall be in effect;

                       (xii)   no other events or developments shall have
                               occurred that, in the sole judgment of Yellow,
                               would result in the Distribution having a
                               material adverse effect on Yellow or its
                               stockholders;

                       (xiii)  Yellow's Board of Directors shall be satisfied
                               that each of Yellow and SCST will be solvent
                               following the Distribution; and

                       (xiv)   SCST shall have made the Yellow Payment.

        1.3 Sale of Fractional Shares. The Distribution Agent shall not
distribute any fractional shares of SCST Common Stock ("Fractional Shares") to
any record holder of Yellow Common Stock in connection with the Distribution.
The Distribution Agent shall be instructed to aggregate all such Fractional
Shares and sell them in an orderly manner promptly after the Distribution Date
in the open market at the then-prevailing prices and, after completion of all
such sales, distribute a pro rata portion of the gross proceeds from such sales,
less appropriate deductions of the amount required to be withheld for federal
income tax purposes, to each record holder of Yellow Common Stock who would
otherwise have received a Fractional Share. Yellow shall pay all brokerage
charges, commissions and transfer taxes attributed to such sale.

        1.4 Sole Discretion of Yellow. The conditions set forth in Section 1.2
are for the sole benefit of Yellow and shall not give rise to or create any duty
on the part of Yellow or Yellow's Board of Directors to waive or not to waive
such conditions or limit in any way Yellow's right to terminate this Agreement
or alter the consequences of any such termination. Any determination made by
Yellow prior to the Distribution concerning the satisfaction or waiver of any or
all of the conditions set forth in Section 1.2 shall be conclusive. In addition,

<PAGE>
                                      -5-

Yellow shall have the sole and absolute discretion to determine the date of
consummation of the Distribution (such date, the "Distribution Date"), all terms
of the Distribution, including without limitation the form, structure and terms
of any transaction(s) and/or offering(s) to effect the Distribution or related
to the Distribution and the timing of and conditions to the consummation of the
Distribution. In addition, Yellow may in its sole and absolute discretion at any
time and from time to time until the Distribution Date, modify or change the
terms of the Distribution, including without limitation accelerating or delaying
the timing of the consummation of all or part of the Distribution. SCST shall
cooperate with Yellow in all respects to accomplish the Distribution and shall,
at Yellow's direction, promptly take any and all actions necessary and desirable
to effect the Distribution, including without limitation the registration under
the Exchange Act of the SCST Common Stock on an appropriate registration form.
Yellow shall in its sole and absolute discretion select any investment bank and
managers in connection with the Distribution, as well as any financial printer,
solicitation and/or exchange agent and its own outside counsel.

        1.5 Termination of Obligations. The obligations of Yellow and SCST under
this Agreement shall terminate on a determination by Yellow to terminate the
transactions that comprise the Distribution.

                                   ARTICLE II

                       DIVISION OF ASSETS AND LIABILITIES

        2.1 Transfer of Assets and Liabilities.

this Agreement and with effect as of the Contribution Date, Yellow hereby
contributes, assigns, transfers, conveys and delivers to SCST, and shall cause
its applicable Subsidiaries to contribute, assign, transfer, convey and deliver
to SCST or a member of the SCST Group, all of Yellow's and such applicable
Subsidiaries' respective rights, title and interest in and to the assets set

SCST, or the appropriate member of the SCST Group, hereby accepts from Yellow

Agreement and with effect as of the Contribution Date, SCST hereby accepts,
assumes and agrees faithfully to perform, discharge and fulfill all the
liabilities set forth in paragraph 2.1 of the Disclosure Letter (the
"Contributed Liabilities") in accordance with their respective terms, and agrees
to cause its applicable Subsidiaries to accept, assume, perform, discharge and
fulfill all the Contributed Liabilities to be held by its Subsidiaries in

<PAGE>
                                      -6-

(i) when or where such liabilities arose or arise, (ii) whether the facts on
which they are based occurred prior to or subsequent to the date hereof, (iii)
where or against whom such liabilities are asserted or determined (including
without limitation any liabilities arising out of claims made by Yellow's or
SCST's respective directors, officers, employees, agents, Subsidiaries or
Affiliates against any member of the Yellow Group or the SCST Group), (iv)
whether such liabilities were asserted or determined prior to the date hereof,
and (v) whether such liabilities arise from or are alleged to arise from
negligence, recklessness, violation of law, fraud or misrepresentation by any
member of the Yellow Group or the SCST Group or any of their respective
directors, officers, employees, agents, Subsidiaries or Affiliates.

               (c) In the event that at any time or from time to time (whether

such party's respective Group) shall receive or otherwise possess any asset that
is allocated to any other Person pursuant to this Agreement, such party shall
promptly transfer, or cause to be transferred, such asset to the Person so
entitled thereto. Prior to any such transfer, the party possessing such asset
shall hold such asset in trust for any such other party, and upon such transfer
each party shall reimburse the other or make financial or other adjustments to
remedy any liabilities resulting from such transfer or possession.

listed in paragraph 2.2 of the Disclosure Letter shall become employees of SCST
(the "Allocated Employees"). Yellow shall not be responsible for insurance,
employee benefits and other related benefits of the Allocated Employees that
accrue from and after the Distribution Date except as may be provided in an

Yellow determines that it has made any direct or indirect payment in respect
thereof, including without limitation as a result of adjustment to its insurance
rates or government fund payment obligations. SCST's health and life insurance
plans will not exclude pre-existing conditions for the Allocated Employees
(except to the extent such pre-existing conditions were excluded from the
corresponding Yellow plan immediately prior to the Distribution Date), will
waive any waiting period requirements for the Allocated Employees, and will
waive any evidence of insurability provisions for the Allocated Employees. In

waive the shares of SCST Common Stock that they would otherwise have received in
exchange for additional restricted shares of Yellow Common Stock commensurate in
value to the impact of the Distribution on the value of their previous
restricted stock grants. The additional grants of restricted stock will be
subject to the same restrictions and vesting dates as the original grants.

                      other person in accordance with the documentation
                      governing such Guarantee. With respect to any Guarantees
                      the cancellation of which requires the consent of a third
                      party, SCST shall, subject to the following sentence, use
                      its reasonable best efforts following the Distribution

                      Guarantee in accordance with Section 4.3. SCST shall not
                      be required to offer monetary compensation to any holder

                               Distribution Date under any and all former or
                               current insurance policies maintained by Yellow
                               and related to liabilities or losses of SCST or
                               its Subsidiaries prior to the Distribution Date
                               shall be allocated by Yellow to SCST or Yellow

                               basis not inconsistent with past practices
                               between Yellow and SCST. To the extent that any
                               party pays any expenses that were determined by
                               Yellow to be properly allocable to the other
                               party, such other party shall reimburse the
                               paying party in accordance with the procedures
                               set forth in Section 4.4.

                      2.5.2.2  Self-Insurance Pool and AIT "Bank". As of the
                               Distribution Date, a calculation shall be made by
                               Yellow of the total of all premiums paid since
                               inception by SCST and its Subsidiaries for
                               coverage under the self-insurance retention pool
                               which has been maintained by Yellow to buy down
                               the self-insurance retentions of Jevic and Saia
                               (and Action Express, Inc. and WestEx, Inc.,
                               merged into Saia effective March 4, 2001) from
                               external retention levels of third-party
                               insurance providers. To this amount there shall
                               be added $1,014,783.00, representing SCST's and
                               its Subsidiaries' shares of the "bank" that has
                               been established with AI Transport, Inc. of
                               Atlanta, Georgia ("AIT") relating to certain
                               third-party liability claims incurred by Yellow
                               and SCST's Subsidiaries over the course of
                               Yellow's insurance arrangements with AIT. All
                               payments made by AIT to Yellow prior to or after
                               the Distribution Date shall be retained solely by
                               Yellow.

                               From the total derived in the preceding
                               paragraph, there shall be subtracted a sum equal
                               to a calculation made by Yellow of the actual
                               claim payments made by Yellow to resolve claims
                               involving SCST and its Subsidiaries within the

                               calculation hereinafter being referred to as the
                               "Net Ultimate Liability of Yellow" and the
                               calculation being detailed in paragraph 2.5.2.2
                               of the Disclosure Letter).

                               Yellow to fall within the self-insurance pool
                               that arise out of, in connection with or with
                               reference to activity of SCST and its
                               Subsidiaries prior to the Distribution Date
                               (together the "SCST Excess Liability") shall be
                               paid first by Yellow after the Distribution Date
                               up to the Net Ultimate Liability of Yellow. If
                               and when said Net Ultimate Liability of Yellow is
                               exhausted, all remaining liability for SCST
                               Excess Liability shall be paid by SCST and its
                               Subsidiaries, and SCST shall indemnify Yellow for
                               any claims asserted against Yellow for amounts of
                               SCST Excess Liability in excess of the Net
                               Ultimate Liability of Yellow in accordance with
                               Section 4.3. SCST shall reimburse Yellow in
                               accordance with the procedures set forth in
                               Section 4.4 if Yellow determines that Yellow or
                               any of its Subsidiaries has made any direct or
                               indirect payment in respect of SCST Excess
                               Liability in excess of the Net Ultimate Liability
                               of Yellow.

                                        fiscal quarter plus (b) 100 basis points
                                        multiplied by the average daily face
                                        amount of the Collateral for such fiscal
                                        quarter as determined by Yellow.

                                    (6) Collateral Cost for any fiscal quarter
                                        ending after the seventh anniversary of
                                        the Distribution Date shall equal the
                                        sum of (a) the Billed Cost for such
                                        fiscal quarter plus (b) 125 basis points
                                        multiplied by the average daily face
                                        amount of the Collateral for such fiscal
                                        quarter as determined by Yellow.

                               The Collateral Cost shall be billed on a
                               quarterly basis in arrears following the
                               Distribution Date. If Yellow receives a refund
                               from collateral providers for the Billed Cost of
                               Collateral that SCST has replaced following
                               Yellow's payment of the annual cost of such
                               Collateral, Yellow shall reimburse SCST the
                               amount of such Billed Cost and related premium
                               paid by SCST or any of its Subsidiaries to Yellow
                               or any of its Subsidiaries within 15 calendar
                               days of receipt by Yellow of such refund. Payment
                               of the Collateral Cost by SCST shall be due
                               within 15 calendar days after receipt by SCST of
                               the applicable Yellow bill or invoice.

                               After the Distribution, Yellow shall leave
                               existing Collateral in place until such
                               Collateral has been released by its holders,
                               except that SCST immediately after the
                               Distribution shall replace $15 million of the
                               existing Collateral detailed in paragraph 2.5.2.3
                               of the Disclosure Letter with Collateral obtained
                               by SCST. Notwithstanding the foregoing, in the
                               event that SCST experiences demands for increased
                               Collateral from any of the holders of such
                               Collateral detailed in paragraph 2.5.2.3 of the
                               Disclosure Letter between the Distribution Date
                               and February 28, 2003, Yellow shall either
                               provide such increased Collateral or instruct
                               SCST to provide such increased Collateral with a
                               credit against SCST's replacement Collateral
                               obligation described above, at Yellow's option.

                               Yellow shall provide no additional Collateral to
                               SCST or any of SCST's Subsidiaries for any
                               insurance or self-insurance obligations arising
                               after February 28, 2003.

                               Notwithstanding the foregoing, in the event that
                               any holder of any Collateral provided by Yellow
                               redeems or calls such Collateral, SCST shall be
                               required to reimburse Yellow in accordance with
                               the procedures set forth in Section 4.4 and to
                               indemnify and hold Yellow harmless in accordance
                               with Section 4.3.

                      2.5.2.4  Claims Administration Obligations. Yellow and
                               SCST acknowledge that Yellow currently receives
                               invoices for claims administration expenses
                               provided by third-party administrators ("TPAs")
                               that pertain in whole or in part to the handling
                               and disposition of claims on behalf of Saia under
                               SCST's and Saia's insurance programs for years
                               prior to the year ended March 1, 2000. Yellow
                               shall continue to pay such invoices by TPAs after
                               the Distribution Date and SCST and Saia shall be
                               jointly or severally obligated to reimburse
                               Yellow for the portion of such invoices which
                               relate to services performed by TPAs on behalf of
                               Saia. Yellow shall not pay the portion of any
                               such invoices as relate to services performed on
                               behalf of Saia until SCST and/or Saia has
                               verified in writing the correctness of the
                               billing, which SCST or Saia must do within
                               fifteen (15) calendar days of presentment of the
                               invoice by Yellow to SCST. If SCST or Saia does
                               not deliver such written verification on or prior
                               to the date that is fifteen (15) calendar days
                               after the presentment of such invoice, Yellow
                               shall regard SCST as having verified such
                               invoice. Yellow will use its reasonable efforts
                               to contest any such billing on Saia's behalf, and
                               the parties will provide all reasonable
                               cooperation required to resolve any billing
                               disputes. If Yellow and SCST decide not to pay a
                               disputed invoice or to pay only a portion
                               thereof, SCST will indemnify Yellow from any
                               damages or costs incurred by Yellow stemming from
                               such non-payment or partial payment in accordance
                               with Section 4.3. SCST or Saia, as the case may
                               be, shall reimburse Yellow within fifteen (15)
                               calendar days of Yellow's payment of that portion
                               of each TPA invoice that relates to performance
                               by TPAs of services on their behalf.

                      former subsidiary Preston Trucking Company, Inc.

                      the bankruptcy of Preston, whether already incurred or to

                      responsibility of Yellow, and Yellow shall be the sole
                      beneficiary of any payment of the claim in bankruptcy that
                      has been filed by Yellow against Preston, either for
                      amounts already claimed or to be claimed in the future,

                      Preston, that is presently held by Yellow. Following the
                      Distribution Date, Yellow shall indemnify and hold SCST
                      harmless in accordance with Section 4.3 for claims which
                      in any manner relate to or stem from the bankruptcy of
                      Preston and the former ownership of Preston by Yellow.

                      future prosecution of any claim against Luciano and/or
                      Luis Saia, III for these unpaid interline receivables
                      after the Distribution and SCST and/or Saia shall be the
                      recipients of any and all judgment, settlement or other
                      recovery ultimately achieved as a result of or in
                      connection with such litigation against Luciano and Luis
                      Saia, III, after the payment to Yellow of all expenses,
                      including without limitation attorneys' fees up to a
                      maximum of $25,000, that Yellow determines that it or any
                      of its Subsidiaries (other than SCST or Saia) has incurred
                      in the prosecution of this claim prior to the Distribution
                      (together, the "Yellow Luciano Litigation Expenses").
                      Amounts received by SCST or Saia as a result of or in
                      connection with such litigation shall be paid first to
                      Yellow in full satisfaction of the Yellow Luciano

                      sight as the TPA of Saia's medical plan. SCST and Saia

                      any claim against Benesight and SCST and Saia shall be the
                      recipients of any and all judgment, settlement or other
                      recovery ultimately achieved as a result of such
                      litigation against Benesight, after the payment to Yellow
                      of all expenses, including without limitation attorneys'
                      fees up to a maximum of $20,000, that Yellow determines
                      that it or any of its Subsidiaries (other than SCST or
                      Saia) has incurred in the prosecution of this claim prior
                      to the Distribution (together, the "Yellow Benesight
                      Litigation Expenses"). Amounts received by SCST or Saia as
                      a result of or in connection with such litigation shall be
                      paid first to Yellow in full satisfaction of the Yellow
                      Benesight Litigation Expenses, promptly upon receipt
                      thereof by any member of the SCST Group, and then to SCST
                      or another member of the SCST Group.

               2.6.4  Remaining Action Express Purchase Obligations. Pursuant to

                      Fulkerson and Yellow for the issued and outstanding shares
                      of Action Express, Inc. (merged into Saia effective March

                      2006 and January 31, 2005, respectively. The
                      responsibility for all such payments after the
                      Distribution shall rest with SCST and/or Saia, and SCST

                      connection with the acquisition by Yellow of Jevic on July

                      agreements (the "Jevic Employment Agreements") with
                      certain senior officers of Jevic, which employment

                      Yellow in connection herewith constitute or will, when
                      executed and delivered, constitute the valid and legally
                      binding obligations of Yellow, enforceable against it in
                      accordance with their respective terms, except as
                      enforceability may be limited by applicable equitable
                      principles or by bankruptcy, insolvency, reorganization,
                      moratorium or similar laws from time to time affecting the
                      enforcement of creditors' rights generally.

               (c)    Litigation. To the knowledge of Yellow, there is no claim,
                      litigation, action, suit or proceeding, administrative or
                      judicial, pending or threatened against Yellow or related
                      to the business or the assets transferred pursuant to this
                      Agreement or the transactions contemplated hereunder, at
                      law or in equity, before any federal, state, local or
                      foreign court or regulatory agency, or other governmental
                      authority, which could result

                                      -16-

                      in the institution of legal proceedings to prohibit or
                      restrain the consummation or performance of this Agreement
                      or the transactions contemplated hereby, or claim damages
                      as a result of this Agreement or the transactions
                      contemplated hereby.

               (d)    No Conflict. Neither the execution and delivery of this
                      Agreement and the Tax Sharing Agreement nor compliance
                      with the terms and provisions hereof and thereof,
                      including, without limitation, the consummation of the
                      transactions contemplated hereby and thereby, will
                      conflict with or result in the breach of any term,
                      condition or provisions of Yellow's Certificate of
                      Incorporation or By-laws or applicable law, regulation or
                      court order.

        3.2 Representations and Warranties of SCST. SCST represents and warrants
to Yellow as follows:

               (a) Organization and Standing. SCST is a corporation duly
        organized, validly existing and in good standing under the laws of the
        state of Delaware.

               (b) Authority and Status. SCST has full power and authority to
        execute and deliver this Agreement and the Tax Sharing Agreement, to
        perform its obligations hereunder and thereunder and consummate the
        transactions contemplated hereby and thereby without the necessity of
        any act or consent of any other person. SCST has taken all necessary and
        appropriate corporate action, including obtaining all necessary board
        and shareholder consents with respect to the execution, delivery and
        performance by SCST of this Agreement and of the Tax Sharing Agreement.
        This Agreement and the Tax Sharing Agreement constitute or will when
        executed and delivered constitute the valid and legally binding
        obligation of SCST enforceable against it in accordance with their
        respective terms, except as enforceability may be limited by applicable
        equitable principles or by bankruptcy, insolvency, reorganization,
        moratorium or similar laws from time to time affecting the enforcement
        of creditors' rights generally.

               (c) No Conflict. Neither the execution and delivery of this
        Agreement and the Tax Sharing Agreement nor the terms and provisions
        hereof and thereof including, without limitation, the consummation of
        the transactions contemplated hereby and thereby will conflict with or
        result in the breach of any term, condition or provisions of the
        Certificate of Incorporation or By-laws, as amended and restated, or
        applicable law, regulation or court order.

                                   ARTICLE IV

                                 RELATED MATTERS

        4.1 Access to Information.

               (a) From and after the Distribution Date, each of Yellow and
SCST, on behalf of its respective Group, agrees to provide or cause to be
provided to the other Group any Information in the possession or under the
control of such Group which the requesting party reasonably needs

               (i) to comply with reporting, disclosure, filing or other
        requirements imposed on the requesting party (including under applicable
        securities laws) by a Governmental Authority having jurisdiction over
        the requesting party;

               (ii) for use in any other judicial, regulatory, administrative or
        other proceeding or in order to satisfy audit, accounting, claims,
        regulatory, litigation or other similar requirements, in each case other
        than claims or allegations that one party to this Agreement has against
        the other; or

               (iii) subject to the foregoing clause (ii), to comply with its
        obligations under this Agreement or the Tax Sharing Agreement;

provided, however, that in the event that any party hereto determines that any
such provision of Information could be commercially detrimental, violate any law
or agreement, or waive any attorney-client privilege, the parties shall take all
reasonable measures to permit the compliance with such obligations in a manner
that avoids any such harm or consequence.

               (b) Except as otherwise specifically provided for herein, a
party providing Information or witnesses to the other hereunder shall be
entitled to receive from the recipient, upon the presentation of appropriate
invoices therefor, payments for such amounts relating to supplies, out-of-pocket
expenses, and such other costs, employee time and disbursements, which may be
reasonably incurred in providing such Information or witnesses. Invoices shall
be due and payable within fifteen (15) calendar days of receipt. Employee time
shall be billed at the involved employee's hourly rate for hourly employees with
a four-hour minimum, and salary calculated on a per diem basis for salaried
employees with a one calendar day minimum.

        4.2 Confidentiality. Each of Yellow and its Subsidiaries (other than
SCST and its Subsidiaries) and SCST and its Subsidiaries shall hold and cause
each of their respective officers, directors, employees, agents, consultants and
advisors to hold, in strict confidence, all non-public information concerning
the other party, unless compelled to disclose such informa-

<PAGE>
                                      -18-

tion by judicial or administrative process or, in the opinion of counsel, by the
requirements of law (in which case such party shall promptly notify the other
party so that the other party may seek a protective order or other appropriate
remedy). Each party shall not release or disclose such information to any other
person except its auditors, attorneys, financial advisors, bankers,
subcontractors and other consultants and advisors who have a need to know, who
shall be bound by the provisions of this Section 4.2. Each party shall be deemed
to have satisfied its obligations hereunder with respect to confidential
information supplied by the other party if it exercises the same care as it does
to preserving the confidentiality of its own similar information.

        4.3 Indemnification.

               (a) Except as otherwise provided in this Agreement, Yellow
shall indemnify SCST, its Subsidiaries and their officers, directors, managers,
members, employees, agents, affiliates and advisors (collectively, the "SCST
Indemnitees") from and against and shall reimburse such SCST Indemnitees in
respect of any and all Losses resulting from or arising out of (i) any Yellow
Liabilities (whether arising prior to or after the Distribution Date), (ii) the
failure of Yellow to perform any of its obligations under this Agreement in any
material respect, and (iii) all Liabilities arising out of the business,
operations and assets of Yellow and Yellow's Subsidiaries after the Distribution
Date.

               (b) Except as otherwise provided in this Agreement, SCST shall
indemnify Yellow, its Subsidiaries and their officers, directors, managers,
members, employees, agents, affiliates and advisors (collectively, the "Yellow
Indemnitees") from and against and shall reimburse such Yellow Indemnitees in
respect of any and all Losses resulting from or arising out of (i) any of the
SCST Liabilities (whether arising prior to or after the Distribution Date), (ii)
the failure of SCST to perform any of its obligations under this Agreement in
any material respect, and (iii) all Liabilities arising out of the business,
operations and assets of SCST and SCST's Subsidiaries after the Distribution
Date.

               (c) Any Liabilities not allocated to Yellow or its
Subsidiaries or to SCST or its Subsidiaries hereunder shall be allocated to
either Yellow or SCST by the Chief Executive Officer of Yellow in his sole
discretion.

               (d) Neither party shall be liable for indemnification with
respect to any claim for which indemnification may result hereunder unless the
party seeking indemnification (the "Indemnitee") notifies the other party (the
"Indemnifying Party") in writing of the nature of the claim in as much detail as
is feasible within a reasonable time after the facts giving rise to such claim
are known to the Indemnitee. The Indemnifying Party shall be entitled to
participate at its own expense in the defense or, if it so elects by a writing
delivered to the Indemnitee within thirty (30) calendar days after receipt of
such notice, to assume at its own expense the defense of the matter giving rise
to the claim for indemnification or of any suit

<PAGE>
                                      -19-

brought in connection with it. If the Indemnifying Party elects to assume a
defense and is reasonably creditworthy or carries insurance so as to make it
reasonable to expect it will be able to discharge an adverse judgment, the
defense shall be conducted by counsel chosen by it. Only one counsel will be
provided for the Indemnitee in any one proceeding regardless of the number of
entities or individuals to be indemnified and the Indemnifying Party shall be
able to settle if it obtains an unconditional release without limitations on
future conduct. If the Indemnitee elects to assume the defense of any such claim
or suit and retains such counsel, the Indemnitee shall bear the fees and
expenses of its own counsel arising out of any legal service thereafter
performed by that counsel. In the event the Indemnitee elects to defend against
any such claim it will, so long as the Indemnifying Party is actively engaged in
defense of the claim, refrain from paying or compromising the claim and will
extend its cooperation and assistance to the Indemnifying Party in its defense
against the claim. If the parties hereto or an Indemnitee is unable to agree
upon or settle any claim for indemnity, either party or an Indemnitee may submit
the Indemnitee claim to the dispute resolution procedure provided for herein.
Notwithstanding the foregoing, there shall be no obligation for one party to
indemnify the other for any dispute in which the amount in controversy is less
than $5,000.

        4.4 Manner of Payments. Except as otherwise provided in this Agreement,
any reimbursements or other payments to be made on and after the Distribution
Date by any party to any other party hereunder shall be due within fifteen (15)
calendar days of the receipt by the owing party of an invoice or other billing
documentation accompanied by reasonably detailed supporting information.

        4.5 Taxes. Yellow and SCST have entered into a Tax Sharing Agreement
regarding their respective rights and obligations with respect to taxes of
Yellow and SCST for all periods prior to (or including) the Distribution and
certain other tax related matters. In the event of any conflict between the
terms of the Tax Sharing Agreement and the terms of this Agreement, the terms of
the Tax Sharing Agreement shall prevail.

        4.6 Expenses. Except as otherwise provided in this Agreement or the Tax
Sharing Agreement, all out-of-pocket expenses incurred in connection with the
Distribution up to and including the Distribution Date shall be paid by Yellow.
Thereafter, except as otherwise provided in this Agreement or in the Tax Sharing
Agreement, each party shall bear its own expenses in connection with the
Distribution.

        4.7 Non-solicitation. For twenty-four (24) months after the date hereof,
Yellow and SCST shall not, directly or indirectly, offer, induce, recruit,
solicit, influence or attempt to influence any employee of the other or any of
its subsidiaries to terminate his or her employment for the purpose of working
for the other (without the prior written consent of the other party). This
Section 4.7 shall not prohibit one party from hiring an employee of the other
party if such employment is the result of an employee's soliciting employment by
the employ-

<PAGE>
                                      -20-

ing party without any inducement or attempt by the employing party to encourage
said employee, or if the employment occurs as a result of a general solicitation
for employment by one party not specifically directed at the other party.

                                    ARTICLE V

                               DISPUTE RESOLUTION

        5.1 Use of Dispute Resolution; Presumptions. Except as otherwise set
forth in the Tax Sharing Agreement, resolution of any and all disputes arising
from or in connection with this Agreement or the Tax Sharing Agreement, whether
based on contract, tort or otherwise (collectively, "Disputes"), shall be
exclusively governed by and settled in accordance with the provisions of this
Article V, it being understood and agreed by SCST that any calculation or
determination made by Yellow with respect to or in connection with the
Distribution or this Agreement shall be deemed reasonable and binding on SCST
absent manifest error.

        5.2 Negotiation. The parties shall make a good faith attempt to resolve
any Dispute through negotiation. Within fifteen (15) calendar days after notice
of a Dispute is given by either party to the other party, each party shall
select a negotiating team comprised of vice president-level employees of such
party and shall meet within fifteen (15) calendar days after the end of the
first fifteen (15) calendar day negotiating period to attempt to resolve the
matter. During the course of negotiations under this Section 5.2, all reasonable
requests made by one party to the other for Information, including requests for
copies of relevant documents, will be honored. The specific format for such
negotiations will be left to the discretion of the designated negotiating teams
and may include the preparation of agreed upon statements of fact or written
statements of position furnished to the other party.

        5.3 Non-binding Mediation. In the event that any Dispute arising out of
or related to this Agreement is not settled by the parties within fifteen (15)
calendar days after the first meeting of the vice president-level negotiating
teams under Section 5.2, the parties will attempt in good faith to resolve such
Dispute by non-binding mediation in accordance with the American Arbitration
Association Commercial Mediation Rules as in effect at such time. Mediation
shall be held within thirty (30) calendar days of the end of such fifteen (15)
calendar day negotiation period of the negotiating teams. Except as provided in
Section 5.4, no litigation for the resolution of such Dispute may be commenced
until the parties attempt in good faith to settle the dispute by such mediation
in accordance with such rules and either party has concluded in good faith that
amicable resolution through continued mediation of the matter does not appear
likely. The costs of mediation shall be shared equally by the parties to the
mediation. Any settlement reached by mediation shall be recorded in writing,
signed by the parties, and shall be binding on them.

<PAGE>
                                      -21-

        5.4 Proceedings. Nothing herein, however, shall prohibit either party
from initiating litigation or other judicial or administrative proceedings if
there is a substantial likelihood that such party would be substantially harmed
by a failure to act during the time that such good faith efforts are being made
to resolve the Dispute through negotiation or mediation. In the event that
litigation is commenced under this Section 5.4, the parties agree to continue to
attempt to resolve any Dispute according to the terms of Section 5.2 and Section
5.3 during the course of such litigation proceedings under this Section 5.4.

        5.5 Continuity of Service and Performance. Unless otherwise agreed in
writing, the parties will continue to provide service on all of the commitments
in this Agreement and the Tax Sharing Agreement during the course of dispute
resolution pursuant to the provisions of this Article V with respect to all
matters not subject to the Dispute.

        5.6 Further Assurances. In addition to the actions specifically provided
for elsewhere in this Agreement, each of the parties hereto shall use its
reasonable best efforts to (i) execute and deliver such further documents and
take such other actions as any other party may reasonably request in order to
effectuate the purposes of this Agreement and to carry out the terms hereof, and
(ii) take, or cause to be taken, all actions, and to do or cause to be done all
things reasonably necessary, proper or advisable under applicable law,
regulation and agreements or otherwise to consummate and make effective the
transactions contemplated by this Agreement, including without limitation using
its reasonable best efforts to obtain any consents and approvals and make any
filings and applications necessary or desirable in order to consummate the
transactions contemplated by this Agreement.

                                   ARTICLE VI

        6.1 Survival. The provisions of this Agreement shall survive the
Distribution Date.

        6.2 Entire Agreement. This Agreement supersedes and cancels any and all
previous agreements, written or oral, between the parties relating to the

complete and final understanding of the parties with respect to the subject
matter thereto and may not be changed in any way, except as provided in Section
6.3.

        6.3 Waiver and Modification. An amendment or modification of this
Agreement will be valid and effective only if it is in writing and signed by
each party to this Agreement. In addition, a waiver of any duty, obligation or
responsibility of a party under this Agreement will be valid and effective only
if it is evidenced by writing, signed by or on behalf of the party against whom
the waiver or discharge is sought to be enforced. The waiver by either party of

<PAGE>
                                      -22-

a breach of a provision of this Agreement will not constitute a waiver of the
succeeding breach of the provision or a waiver of the provision itself.

hereunder to any party shall be deemed to be sufficient if contained in a
written instrument delivered in person or sent by telecopy confirmed receipt,
