                        ADMINISTRATIVE SERVICES AGREEMENT

         This Administrative Services Agreement (this "Agreement") is entered
into as of _______, 2001, between Kaneb Services, Inc., a Delaware corporation
("KSI"), and Kaneb Services LLC, a Delaware limited liability company ("KSL").

                                   WITNESSETH

         WHEREAS, KSI and KSL are parties to the Distribution Agreement and
other related agreements; and

         WHEREAS, KSI and KSL desire for KSI and its Affiliates to provide
certain services to KSL and its Affiliates;

         NOW, THEREFORE, in consideration of the premises and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, KSI and KSL hereby covenant and agree as follows:

                                   ARTICLE 1

                                  DEFINITIONS

         All capitalized terms or other defined terms used but not defined in
this Agreement are used in this Agreement with the following meanings:

         "Affiliate" means, with respect to KSI or KSL, any Person, that
directly or indirectly, is in control of, is controlled by, controls or is under
common control of KSI or KSL, as the case may be. For purposes of this
definition, control shall include the ownership of 50% or more of the legal or
beneficial interest in any Person or the power to direct or cause the direction
of the management and policies of such Person, whether through the ownership of
voting securities, by contract or otherwise. A Person who is an Affiliate shall
only be considered an Affiliate for so long as that Person meets the definition
of an Affiliate. An officer, director, general partner, managing member or
trustee of a Person or Affiliate of such Person shall not be considered to be an
Affiliate unless such Person is under the direct or indirect control or common
control of KSI or KSL, as the case may be. For purposes of clarity, neither KSI
nor KSL shall be considered to be an Affiliate of the other, nor shall Kaneb
Pipe Line Partners, L.P. or its subsidiaries be considered an Affiliate of KSL
solely for the purposes of this Agreement.

         "Business Day" shall mean any day other than a Saturday, Sunday or
other day on which commercial banks in Dallas, Texas are authorized or required
to close.

         "Closing Date" shall mean ________ __, 2001.

         "Distribution Agreement" shall mean that certain Distribution Agreement
dated as of April ___, 2001, by and between KSI and KSL, as the same may be
amended and in force and effect from time to time.

         "Governmental Authority" shall mean any nation or government, any state
or other political subdivision thereof and any entity exercising executive,
legislative, judicial, regulatory or administrative functions of or pertaining
to government.

         "Person" shall mean an individual, partnership, corporation, business
trust, limited liability company, limited liability partnership, joint stock
company, trust, unincorporated association, joint venture, Governmental
Authority or other entity of whatever nature.

         "CPI" shall mean the consumer price index for All Urban Consumers
(CPI-U), as published by the Bureau of Labor Statistics of the United States
Department of Labor.

         "Services" shall mean, collectively, the Treasury Services, the
Insurance and Risk Management Services, the Legal Services, the Tax Services,
the MIS Services, the Investor Relations Services, the Facilities Services, the
Human Resources Services and the Accounting Services (each of which, as
hereinafter defined).

                                   ARTICLE 2

                                  KSI SERVICES

         2.1 SERVICES. KSI shall provide, or cause to be provided, the treasury
and cash management services set forth on Annex A (the "Treasury Services"), the
insurance and risk management services set forth on Annex B (the "Insurance and
Risk Management Services"), the legal services set forth on Annex C ( the "Legal
Services"), the tax services set forth on Annex D (the "Tax Services"), the

"Human Resources Services"), the accounting services set forth on Annex I (the

         2.2 FEES; EXPENSES.

               (a) For the provision of the Services, KSL hereby agrees to pay
to KSI $____ per month (the "Monthly Fee"). Upon each anniversary of the date
hereof, the Monthly Fee then in effect shall be increased by that number
obtained by multiplying such Monthly Fee by a fraction, the denominator of which
is the CPI that has been most recently reported by the Bureau of Labor
Statistics on the date of such anniversary (the "Current CPI") and the numerator
of which is the CPI finally determined for the twelfth-preceding month before
the month reported under the Current CPI. Notwithstanding the foregoing, this
Section 2.2(a) shall not have the effect of decreasing the Monthly Fee or, if
the Monthly Fee is ever increased, of decreasing such increased Monthly Fee.

<PAGE>   3

               (b) KSL and KSI hereby acknowledge and agree that the Monthly Fee
only compensates KSI for costs expended in connection with general overhead and
other general business expenses and is not intended to compensate KSI for
out-of-pocket expenses incurred by KSI solely for the benefit of KSL.
Accordingly, KSL hereby agrees to reimburse to KSI any out-of-pocket expenses
that KSI incurs solely for the benefit of KSL, such payment to be made within 30
calendar days after receipt of written notice of KSI incurring such an expense.

               (c) KSL agrees to pay to KSI all overhead and administrative
costs and expenses, except for the salaries and other compensation arrangements
(including amounts expended under benefit plans) of any executive officers of
KSL, incurred by KSI in connection with the provision of general office and
other business services to the executive and administrative departments of KSL,
including, but not limited to, the salaries of support staff and expenses
incurred in connection with telephones, office supplies, office rent, dues and
subscriptions and computer networks and systems.

         2.3 TERM AND TERMINATION. The term of this Agreement shall commence on
the Closing Date and shall continue until, and terminate on, December 31, 2005,
provided, however, that, upon one hundred and twenty (120) days notice to the
other party, each party shall have the right to terminate this Agreement. The
termination of this Agreement shall not release (i) either party from its
liability to the other party under this Agreement arising from a breach of this
Agreement, (ii) either party from its rights and obligations under Article III
or (iii) KSL from its payment obligations under Section 2.2.

All notices, demands and requests will be effective upon actual receipt or, in
the case of delivery by facsimile transmission, the completion of such
transmission during the normal business hours of the recipient. Rejection or
other refusal to accept or the inability to deliver because of changed address
of which no notice was given as provided herein will be deemed to be receipt of
the notice, demand or request sent. By giving to the other party at least 10
Business Days' written notice thereof, a party and its respective permitted
successors and permitted assigns will have the right from time to time and at
any time during the term of this Agreement to change their respective addresses
for notices and each will have the right to specify as its address for notices
any other address within the United States of America.

         4.3 SEVERABILITY. Any provision hereof that is prohibited or
unenforceable in any jurisdiction will, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability without invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction will not invalidate or render unenforceable such provision in any
other jurisdiction.

         4.4 ASSIGNMENT; OTHER BENEFITS. This Agreement will be binding upon and
inure to the benefit of and be enforceable by the parties hereto and their
respective successors and permitted assigns. Neither party to this Agreement may
assign its rights under this Agreement without the prior written consent of the
other party; provided, however, KSI may assign any of its rights and obligations
under this Agreement to any Affiliate of KSI.

         4.5 GOVERNING LAW. This Agreement will be governed by, and construed in
accordance with, the internal laws of the State of Texas, without reference to
or the application of the rules of conflicts of laws set forth in such laws.

         4.6 WAIVER. No consent or waiver, express or implied, by a party hereto
to or of any breach or default by the other party hereto in the performance by
such other party of its obligations hereunder will be deemed or construed to be
a consent or waiver to or of any other breach or default in the performance by
such other party of the same or any other obligations of

                                       6
<PAGE>   7

such other party hereunder. Failure on the part of a party to complain of any
act or failure to act of the other party or to declare the other party in
default, irrespective of how long such failure continues, will not constitute a
waiver by such party of its rights hereunder. The giving of consent by a party
in any one instance will not limit or waive the necessity to obtain such party's
consent in any future instance.

         4.7 TERMINOLOGY. All personal pronouns used in this Agreement, whether
used in the masculine, feminine or neuter gender, will include all other
genders; and the singular will include the plural and vice versa. The headings
of the Articles and Sections of this Agreement are included for convenience only
and will not be deemed to constitute part of this Agreement or to affect the
construction hereof or thereof.

         4.8 FORCE MAJEURE. Except for the obligation of KSL to make payments
hereunder when due and the indemnification obligations arising hereunder,
neither party shall be liable for delays in performance or for non-performance,
directly occasioned or caused by Force Majeure. As used in this Agreement, the
term "Force Majeure" means any event beyond the reasonable control of the party
claiming to be affected thereby, including, without limitation, acts of God,
storms, floods, war, fire, strikes, lockouts or differences with workers, acts
of the public enemy, insurrections, riots or rules or regulations of any
Governmental Authority asserting jurisdiction or control, compliance with which
makes continuance of operations impossible. Inability of either party to secure
funds shall not be regarded as Force Majeure. Upon the occurrence of Force
Majeure, the party affected shall give prompt notice thereof to the other party
and shall, at its cost and expense, do all things commercially reasonable to
remove or mitigate its effect.

         4.9 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which will for all purposes be deemed an original, but all
of which together will constitute one and the same agreement.

         4.10 FURTHER ASSURANCES. Each party hereto agrees to do all acts and
things and to make, execute and deliver such written instruments, as will from
time to time be reasonably required to carry out the terms and provisions of
this Agreement.

of the date first set forth in the introduction to this Agreement.

         THIS RIGHTS AGREEMENT is dated as of _________, 2001 (the "Agreement")
between KANEB SERVICES LLC, a Delaware limited liability company (the
"Company"), and ____________, (the "Rights Agent").

                                   WITNESSETH

         WHEREAS, on _________, 2001 (the "Rights Distribution Declaration
Date"), the Board of Directors of the Company (the "Board of Directors")
authorized and declared a distribution of one Right (as defined herein) for each
share of Common Shares of the Company (the "Common Shares") outstanding at the
close of business on __________, 2001 (the "Record Date"), and has authorized
the issuance of one Right (as such number may hereinafter be adjusted pursuant
to the provisions of Section 11(o) hereof) for each Common Share issued between
the Record Date (whether originally issued or delivered from the Company's
treasury) and the Distribution Date, each Right initially representing the right
to purchase one Common Share, upon the terms and subject to the conditions
hereinafter set forth (the "Rights");

         Section 3. Issue of Rights Certificates.

               (a) Until the earlier of (i) the close of business on the

                                       3
<PAGE>   7

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

               (b) With respect to certificates for the Common Shares
outstanding as of the Record Date, until the Distribution Date, the Rights shall
be evidenced by such certificates for the Common Shares and the registered
holders of the Common Shares shall also be the registered holders of the
associated Rights. Until the earlier of the Distribution Date or the Expiration
Date (as such term is defined in Section 7 hereof), the transfer of any
certificates representing Common Shares in respect of which Rights have been
issued shall also constitute the transfer of the Rights associated with such
Common Shares.

               (c) Rights shall be issued in respect of all Common Shares that
are issued (whether originally issued or from the Company's treasury) after the
Record Date but prior to the earlier of the Distribution Date or the Expiration
Date. Certificates representing such Common Shares shall also be deemed to be
certificates for Rights, and shall bear the following legend:

                  This certificate also evidences and entitles the holder hereof
         to certain Rights as set forth in the Rights Agreement between Kaneb
         Services LLC (the "Company") and the Rights Agent named therein dated
         as of ______, 2001 (the "Rights Agreement"), the terms of which are
         hereby incorporated herein by reference and a copy of which is on file
         at the principal office of the Company, 2435 North Central Expressway,
         Richardson, Texas 75080, and at the principal office of the Rights
         Agent. Under certain circumstances, as set forth in the Rights
         Agreement, such Rights will be evidenced by separate certificates and
         will no longer be evidenced by this certificate. The Company or the
         Rights Agent will mail to the holder of this certificate a copy of the
         Rights Agreement, as in effect on the date of mailing,

                                       4

         without charge, promptly after receipt of a written request therefor.
         Under certain circumstances set forth in the Rights Agreement, Rights
         issued to, or held by, any Person who is, was or becomes an Acquiring
         Person or any Affiliate or Associate thereof (as such terms are defined
         in the Rights Agreement), whether currently held by or on behalf of
         such Person or by any subsequent holder, may become null and void.

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

         Section 4. Form of Rights Certificates.

               (a) The Rights Certificates (and the forms of election to
purchase and of assignment to be printed on the reverse thereof) shall each be
substantially in the form set forth in Exhibit A hereto and may have such marks
of identification or designation and such legends, summaries or endorsements
printed thereon as the Company may deem appropriate and as are not inconsistent
with the provisions of this Agreement, or as may be necessary to comply with any
applicable law or with any rule or regulation made pursuant thereto or with any
rule or regulation of any stock exchange on which the Rights may from time to
time be listed, or to conform to usage. Subject to the provisions of Section 11
and Section 22 hereof, the Rights Certificates, whenever distributed, shall be
dated as of the Record Date and on their face shall entitle the holders thereof
to purchase such number of Common Shares as shall be set forth therein at the
price set forth therein (such exercise price per Common Share, the "Purchase
Price"), but the number of Common Shares purchasable upon the exercise of each
Right and the Purchase Price thereof shall be subject to adjustment as provided
herein.

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

                                        5
<PAGE>   9

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

         Section 5.  Countersignature and Registration.

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

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

         Section 6. Transfer, Split Up, Combination and Exchange of Rights
Certificates; Mutilated, Destroyed, Lost or Stolen Rights Certificates. (a)
Subject to the provisions of Section 4(b), Section 7(e) and Section 14 hereof,
at any time after the close of business on the Distribution Date, and at or
prior to the close of business on the Expiration Date, any Rights Certificate or
Certificates may be transferred, split up, combined or exchanged for another
Rights Certificate or Certificates, entitling the registered holder to purchase
a like number of Common Shares (or, following a Triggering Event, other
securities, cash or other assets, as the case may be) as the Rights Certificate
or Certificates surrendered then entitled such holder (or former holder in the
case of a transfer) to purchase. Any registered holder desiring to transfer,
split up, combine or exchange any Rights Certificate or Certificates shall make
such request in writing delivered to the Rights Agent, and shall surrender the
Rights Certificate or Certificates to be transferred, split up, combined or
exchanged at the principal office or offices of the Rights Agent designated for
such purpose. Neither the Rights Agent nor the Company shall be obligated to
take any action whatsoever with respect to the transfer of any such surrendered
Rights Certificate until the registered holder shall have completed and signed
the certificate contained in the form of assignment on the reverse side of such
Rights Certificate and shall have provided such additional evidence of the
identity of the Beneficial Owner

                                        6
<PAGE>   10

(or former Beneficial Owner) or Affiliates or Associates thereof as the Company
shall reasonably request. Thereupon the Rights Agent shall, subject to Section
4(b), Section 7(e) and Section 14 hereof, countersign and deliver to the Person
entitled thereto a Rights Certificate or Rights Certificates, as the case may
be, as so requested. The Company may require payment of a sum sufficient to
cover any tax or governmental charge that may be imposed in connection with any
transfer, split up, combination or exchange of Rights Certificates.

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

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

               (a) Subject to Section 7(e) hereof, the registered holder of any
Rights Certificate may exercise the Rights evidenced thereby (except as
otherwise provided herein including, without limitation, the restrictions on
exercisability set forth in Section 9(c) and Section 23(a) hereof) in whole or
in part at any time after the Distribution Date upon surrender of the Rights
Certificate, with the form of election to purchase and the certificate on the
reverse side thereof duly executed, to the Rights Agent at the principal office
or offices of the Rights Agent designated for such purpose, together with
payment of the aggregate Purchase Price with respect to the total number of
Common Shares as to which such surrendered Rights are then exercisable, at or
prior to the earlier of (i) the close of business on _________, 2011 (the "Final
Expiration Date"), or (ii) the time at which the Rights are redeemed as provided
in Section 23 hereof (the earlier of (i) and (ii) being herein referred to as
the "Expiration Date").

               (b) The Purchase Price for each Common Share pursuant to the
exercise of a Right shall initially be $______, and shall be subject to
adjustment from time to time as provided in Sections 11 and 13(a) hereof and
shall be payable in accordance with paragraph (c) below.

               (c) Upon receipt of a Rights Certificate representing exercisable
Rights with the form of election to purchase and the certificate duly executed,
accompanied by payment, with respect to each Right so exercised, of the Purchase
Price per Common Share to be purchased as set forth below and an amount equal to
any applicable transfer tax, the Rights Agent shall, subject to Section 20(k)
hereof, thereupon promptly (i)(A) requisition from any transfer agent of the
Common Shares (or make available, if the Rights Agent is the transfer agent for
such shares) certificates for the total number of Common Shares to be purchased
and the Company hereby irrevocably authorizes its transfer agent to comply with
all such requests, or (B) if the Company shall have elected to deposit the total
number of Common Shares issuable upon exercise of the Rights hereunder with a
depositary agent, requisition from the depositary agent depositary receipts
representing such number of Common Shares as are to be purchased (in which case
certificates for the Common Shares represented by such receipts shall be
deposited by the transfer agent with the depositary agent) and the Company will
direct the depositary agent to comply with such request, (ii) requisition from
the

                                        7
<PAGE>   11

Company the amount of cash, if any, to be paid in lieu of fractional shares in
accordance with Section 14 hereof, (iii) after receipt of such certificates or
depositary receipts, cause the same to be delivered to or upon the order of the
registered holder of such Rights Certificate, registered in such name or names
as may be designated by such holder, and (iv) after receipt thereof, deliver
such cash, if any, to or upon the order of the registered holder of such Rights
Certificate. The payment of the Purchase Price shall be made in cash or by
certified bank check or bank draft payable to the order of the Company. If the
Company is obligated to issue other securities (including Common Shares) of the
Company, pay cash and/or distribute other property pursuant to Section 11(a)
hereof, then the Company will make all arrangements necessary so that such other
securities, cash and/or other property are available for distribution by the
Rights Agent, if and when appropriate.

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

                  (e) Notwithstanding anything in this Agreement to the
contrary, from and after the first occurrence of a Section 11(a)(ii) Event, any
Rights beneficially owned by (i) an Acquiring Person or an Associate or
Affiliate of an Acquiring Person, (ii) a transferee of an Acquiring Person (or
of any such Associate or Affiliate) who becomes a transferee after the Acquiring
Person becomes such, or (iii) a transferee of an Acquiring Person (or of any
such Associate or Affiliate) who becomes a transferee prior to or concurrently
with the Acquiring Person becoming such and receives such Rights pursuant to
either (A) a transfer (whether or not for consideration) from the Acquiring
Person to holders of equity interests in such Acquiring Person or to any Person
with whom the Acquiring Person has any continuing agreement, arrangement or
understanding regarding the transferred Rights or (B) a transfer that the Board
of Directors has determined is part of a plan, arrangement or understanding that
has as a primary purpose or effect the avoidance of this Section 7(e), shall
become null and void 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 insure that the provisions of this Section 7(e) and Section 4(b)
hereof are complied with, but shall have no liability to any holder of Rights
Certificates or other Person as a result of its failure to make any
determinations with respect to an Acquiring Person or its Affiliates, Associates
or transferees hereunder.

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

         Section 8. Cancellation and Destruction of Rights Certificates. All
Rights Certificates surrendered for the purpose of exercise, transfer, split up,
combination or exchange shall, if surrendered to the Company or any of its
agents, be delivered to the Rights Agent for cancellation

                                        8
<PAGE>   12

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

         Section 9. Listing and Registration of Common Shares.

               (a) So long as the Common Shares issuable and deliverable upon
the exercise of the Rights may be listed on any national securities exchange,
the Company shall use its best efforts to cause, from and after such time as the
Rights become exercisable, that number of Common Shares that the Company would
issue upon the full exercise of the Rights to be listed on such exchange upon
official notice of issuance upon such exercise.

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

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

               (d) The Company further covenants and agrees that it will pay
when due and payable any and all federal and state transfer taxes and charges
that may be payable in respect of the issuance or delivery of the Rights
Certificates and of any certificates for a number of Common

                                        9
<PAGE>   13

Shares upon the exercise of Rights. The Company shall not, however, be required
to pay any transfer tax that may be payable in respect of any transfer or
delivery of Rights Certificates to a Person other than, or the issuance or
delivery of Common Shares in respect of a name other than that of, the
registered holder of the Rights Certificates evidencing Rights surrendered for
exercise or to issue or deliver any certificates for Common Shares in a name
other than that of the registered holder upon the exercise of any Rights until
such tax shall have been paid (any such tax being payable by the holder of such
Rights Certificate at the time of surrender) or until it has been established to
the Company's satisfaction that no such tax is due.

         Section 10. Common Shares Record Date. Each person in whose name any
certificate for a Common Share is issued upon the exercise of Rights shall for
all purposes be deemed to have become the holder of record of such Common Share
represented thereby on, and such certificate shall be dated, the date upon which
the Rights Certificate evidencing such Rights was duly surrendered and payment
of the Purchase Price (and all applicable transfer taxes) was made; provided,
however, that if the date of such surrender and payment is a date upon which the
Common Share transfer books of the Company are closed, such Person shall be
deemed to have become the record holder of such shares (fractional or otherwise)
on, and such certificate shall be dated, the next succeeding Business Day on
which the Common Share transfer books of the Company are open. Before the
exercise of the Rights evidenced thereby, the holder of a Rights Certificate
shall not be entitled to any rights of a shareholder of the Company with respect
to shares for which the Rights shall be exercisable, including, without
limitation, the right to vote, to receive distributions or to exercise any
preemptive rights, and shall not be entitled to receive any notice of any
proceedings of the Company, except as provided herein.

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

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

                                       10
<PAGE>   14

         adjustment provided for in this Section 11(a)(i) shall be in addition
         to, and shall be made before, any adjustment required pursuant to
         Section 11(a)(ii) hereof.

                  (ii) In the event:

                           (A) any Acquiring Person or any Associate or
                  Affiliate of any Acquiring Person, at any time after the date
                  of this Agreement, directly or indirectly, (1) shall merge
                  into the Company or otherwise combine with the Company and the
                  Company shall be the continuing or surviving entity of such
                  merger or combination and the Common Shares of the Company
                  shall remain outstanding and unchanged, (2) shall, in one
                  transaction or a series of transactions, transfer any assets
                  to the Company or to any of its Subsidiaries in exchange (in
                  whole or in part) for Common Shares, for member interests of
                  the Company or for securities exercisable for or convertible
                  into member interests of the Company (Common Shares or
                  otherwise) or otherwise obtain from the Company, with or
                  without consideration, any additional member interests or
                  securities exercisable for or convertible into member
                  interests (other than pursuant to a pro rata distribution to
                  all holders of Common Shares), (3) shall sell, purchase,
                  lease, exchange, mortgage, pledge, transfer or otherwise
                  acquire or dispose of, in one transaction or a series of
                  transactions, to, from or with (as the case may be) the
                  Company or any of its Subsidiaries, assets on terms and
                  conditions less favorable to the Company than the Company
                  would be able to obtain in arm's length negotiation with an
                  unaffiliated third party, other than pursuant to a transaction
                  set forth in Section 13(a) hereof, (4) shall sell, purchase,
                  lease, exchange, mortgage, pledge, transfer or otherwise
                  acquire or dispose of in one transaction or a series of
                  transactions, to, from or with (as the case may be) the
                  Company or any of the Company's Subsidiaries (other than
                  incidental to the lines of business, if any, engaged in as of
                  the date hereof between the Company and such Acquiring Person
                  or Associate or Affiliate) assets having an aggregate fair
                  market value of more than $15,000,000, other than pursuant to
                  a transaction set forth in Section 13(a) hereof, (5) shall
                  receive any compensation from the Company or any of the
                  Company's Subsidiaries other than compensation for full-time
                  employment as a regular employee at rates in accordance with
                  the Company's (or its Subsidiaries)) past practices, or (6)
                  shall receive the benefit, directly or indirectly (except
                  proportionately as a shareholder and except if resulting from
                  a requirement of law or governmental regulation), of any
                  loans, advances, guarantees, pledges or other financial
                  assistance or any tax credits or other tax advantage provided
                  by the Company or any of its Subsidiaries, or

                           (B) any Person (other than the Company, any
                  Subsidiary of the Company, Kaneb Services, Inc. (until
                  ________, 2001), any employee benefit plan of the Company or
                  of any Subsidiary of the Company, or any Person or entity
                  organized, appointed or established by the Company for or
                  pursuant to the terms of any such plan), alone or together
                  with its Affiliates and Associates, shall, at any time after
                  the Rights Distribution Declaration Date, become the
                  Beneficial Owner of 20% or more of the Common Shares then
                  outstanding, unless the event causing the 20% threshold to be
                  crossed is a transaction set forth in Section 13(a) hereof, or
                  is an acquisition of

                                       11
<PAGE>   15

                  Common Shares pursuant to a tender offer or an exchange offer
                  for all outstanding Common Shares at a price and on terms
                  determined by at least a majority of the members of the Board
                  of Directors who are not officers of the Company and who are
                  not representatives, nominees, Affiliates or Associates of an
                  Acquiring Person, after receiving advice from one or more
                  investment banking firms, to be (a) at a price that is fair to
                  shareholders of the Company (taking into account all factors
                  which such members of the Board of Directors deem relevant
                  including, without limitation, prices that could reasonably be
                  achieved if the Company or its assets were sold on an orderly
                  basis designed to realize maximum value) and (b) otherwise in
                  the best interests of the Company and its shareholders, or

                           (C) during such time as there is an Acquiring Person
                  there shall be any reclassification of securities (including
                  any reverse stock split), or recapitalization of the Company,
                  or any merger or consolidation of the Company with any of its
                  Subsidiaries or any other transaction or series of
                  transactions involving the Company or any of its Subsidiaries,
                  other than a transaction or transactions to which the
                  provisions of Section 13(a) apply (whether or not with or into
                  or otherwise involving an Acquiring Person) that has the
                  effect, directly or indirectly, of increasing by more than 1%
                  the proportionate share of the outstanding shares of any class
                  of equity securities of the Company or any of its Subsidiaries
                  that is directly or indirectly beneficially owned by any
                  Acquiring Person or any Associate or Affiliate of any
                  Acquiring Person,

         then, promptly following five (5) days after the date of the occurrence
         of an event described in Section 11(a)(ii)(B) hereof and promptly
         following the occurrence of any event described in Section 11(a)(ii)(A)
         or (C) hereof, each holder of a Right (except as provided below and in
         Section 7(e) hereof) shall thereafter have the right to receive, upon
         exercise thereof at the then-current Purchase Price in accordance with
         the terms of this Agreement, such number of Common Shares of the
         Company as shall equal the result obtained by (x) multiplying the
         then-current Purchase Price by the then-number of Common Shares for
         which a Right was exercisable immediately prior to the first occurrence
         of a Section 11(a)(ii) Event, and (y) dividing that product (which,
         following such first occurrence, shall thereafter be referred to as the
         "Purchase Price" for each Right and for all purposes of this Agreement)
         by 50% of the current market price (determined pursuant to Section
         11(d) hereof) per Common Share on the date of such first occurrence
         (such number of shares, the "Adjustment Shares").

               (b) In case the Company shall fix a record date for the issuance
of rights, options or warrants to all holders of Common Shares entitling them to
subscribe for or purchase (for a period expiring within forty-five (45) calendar
days after such record date) Common Shares or securities convertible or
exercisable into Common Shares at a price per Common Share (or having a
conversion price per share, if a security is convertible into Common Shares)
less than the current market price (as determined pursuant to Section 11(d)
hereof) per Common Share on such record date, then the Purchase Price to be in
effect after such record date shall be determined by multiplying the Purchase
Price in effect immediately prior to such record date by a fraction, the
numerator of which shall be the number of Common Shares outstanding on such
record date, plus the number of Common Shares that the aggregate offering price
of the total number of Common Shares so to be

                                       12
<PAGE>   16

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 Common Shares outstanding on
such record date, plus the number of additional Common Shares to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible). In case such subscription price may be paid
by delivery of consideration part or all of which may be in a form other than
cash, the value of such consideration shall be as determined in good faith by
the Board of Directors, whose determination shall be described in a statement
filed with the Rights Agent and shall be binding on the Rights Agent and the
holders of the Rights. Common Shares 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 if such rights or warrants are not so issued, the Purchase Price shall be
adjusted to be the Purchase Price that would then be in effect if such record
date had not been fixed.

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

               (d) For the purpose of any computation hereunder, the "current
market price" per Common Share on any date shall be deemed to be the average of
the daily closing prices per Common Share for the thirty (30) consecutive
Trading Days (as such term is hereinafter defined) immediately prior to such
date; provided, however, that in the event that the current market price per
Common Share is determined during a period following the announcement by the
issuer of such Common Share of (A) a distribution on such Common Share payable
in Common Shares or securities convertible into Common Shares (other than the
Rights), or (B) any subdivision, combination or reclassification of Common
Shares, and prior to the expiration of the requisite thirty (30) Trading Day or
ten (10) Trading Day period, as set forth above, after the ex-distribution date
for such distribution, or the record date for such subdivision, combination or
reclassification, then, and in each such case, the "current market price" shall
be properly adjusted to take into account ex- distribution trading so as to
include the value of the distribution. 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

                                       13
<PAGE>   17

transaction reporting system with respect to securities listed or admitted to
trading on the New York Stock Exchange or, if the Common Shares are not listed
or admitted to trading on the New York Stock Exchange, as reported in the
principal consolidated transaction reporting system with respect to securities
listed on the principal national securities exchange on which the Common Shares
are listed or admitted to trading or, if the Common Shares are not listed or
admitted to trading on any national securities exchange, the last quoted price
or, if not so quoted, the average of the high bid and low asked prices in the
over-the-counter market, as reported by the National Association of Securities
Dealers, Inc. Automated Quotation System ("NASDAQ") or such other system then in
use, or, if on any such data the Common Shares are not quoted by any such
organization, the average of the closing bid and asked prices as furnished by a
professional market maker making a market in the Common Shares selected by the
Board of Directors of the Company. If on any such date no market maker is making
a market in the Common Shares, the fair value of such shares on such date as
determined in good faith by Board of Directors shall be used. The term "Trading
Day" shall mean a day on which the principal national securities exchange on
which the Common Shares are listed or admitted to trading is open for the
transaction of business, if the Common Shares are not listed or admitted to
trading on any national securities exchange, a Business Day. If the Common
Shares are not publicly held or not so listed or traded, "current market price"
per share shall mean the fair value per share as determined in good faith by the
Board of Directors, whose determination shall be described in a statement filed
with the Rights Agent and shall be conclusive for all purposes.

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

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

               (g) All Rights originally issued by the Company after any
adjustment made to the Purchase Price hereunder shall evidence the right to
purchase, at the adjusted Purchase Price, the number of Common Shares
purchasable from time to time hereunder upon exercise of the Rights, all subject
to further adjustment as provided herein.

               (h) Unless the Company shall have exercised its election as
provided in Section 11(i), upon each adjustment of the Purchase Price as a
result of the calculations made in Sections 11(b) and (c), each Right
outstanding immediately prior to the making of such adjustment shall

                                       14
<PAGE>   18

thereafter evidence the right to purchase, at the adjusted Purchase Price, that
number of Common Shares (calculated to the nearest tenth) obtained by (i)
multiplying (x) the number of Common Shares covered by a Right immediately prior
to this adjustment, by (y) the Purchase Price in effect immediately prior to
such adjustment of the Purchase Price, and (ii) dividing the product so obtained
by the Purchase Price in effect immediately after such adjustment of the
Purchase Price.

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

               (j) Irrespective of any adjustment or change in the Purchase
Price or the number of Common Shares issuable upon the exercise of the Rights,
the Rights Certificates theretofore and thereafter issued may continue to
express the Purchase Price per Common Share and the number of Common Shares that
were expressed in the initial Rights Certificates issued hereunder.

               (k) In any case in which this Section 11 shall require that an
adjustment in the Purchase Price be made effective as of a record date for a
specified event, the Company may elect to defer until the occurrence of such
event the issuance to the holder of any Right exercised after such record date
the number of Common Shares issuable upon such exercise over and above the
number of Common Shares 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 holder a due bill or other appropriate instrument evidencing
such holder's right to receive such additional shares (fractional or otherwise)
or securities upon the occurrence of the event requiring such adjustment.

                                       15

               (l) Anything in this Section 11 to the contrary notwithstanding
the Company shall be entitled to make such reductions in the Purchase Price, in
addition to those adjustments expressly required by this Section 11, as and to
the extent that in their good faith judgment the Board of Directors of the
Company shall determine to be advisable so that any (i) consolidation or
subdivision of the Common Shares, (ii) issuance wholly for cash of any Common
Shares at less than the current market price, (iii) issuance wholly for cash of
Common Shares or securities that by their terms are convertible into or
exchangeable for Common Shares, (iv) distributions of member interests or (v)
issuance of rights, options or warrants referred to in this Section 11,
hereafter made by the Company to holders of its Common Shares shall not be
taxable to such shareholders.

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

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

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

         Section 12. Certificate of Adjusted Purchase Price or Number of
Shares. Whenever an adjustment is made as provided in Section 11 and Section 13
hereof, the Company shall (a) promptly prepare a certificate setting forth such
adjustment and a brief statement of the facts accounting for

                                       16
<PAGE>   20

such adjustment, (b) promptly file with the Rights Agent, and with each transfer
agent for the Common Shares, a copy of such certificate, and (c) mail a brief
summary thereof to each holder of a Rights Certificate (or, if prior to the
Distribution Date, to each holder of a certificate representing Common Shares)
in accordance with Section 25 hereof. The Rights Agent shall be fully protected
in relying on any such certificate and on any adjustment therein contained.

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

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

                                       17
<PAGE>   21

and (2) in the case of clause (z), such person is the Company and/or any
Subsidiary of the Company and the transaction or transactions comply with
Section 11(n) hereof.

               (b) "Principal Party" shall mean

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

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

provided, however, that in any such case, (1) if the Common Shares of such
Person is not at such time and has not been continuously over the preceding
twelve (12) month period registered under Section 12 of the Exchange Act, and
such Person is a direct or indirect Subsidiary of another Person the Common
Shares of which is and has been so registered, "Principal Party" shall refer to
such other Person; and (2) in case such Person is a Subsidiary, directly or
indirectly, of more than one Person, the Common Shares of two or more of which
are and have been so registered, "Principal Party" shall refer to whichever of
such Persons is the issuer of the Common Shares having the greatest aggregate
market value.

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

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

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

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

                                       18
<PAGE>   22

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

         Section 14. Fractional Rights and Fractional Shares.

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

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

                                       19
<PAGE>   23

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

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

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

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

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

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

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

                                       20
<PAGE>   24

Rights Agent, subject to the last sentence of Section 7(e) hereof, shall be
required to be affected by any notice to the contrary; and

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

         Section 17. Rights Certificate Holder Not Deemed a Shareholder. No
holder, as such, of any Rights Certificate shall be entitled to vote, receive
distributions or be deemed for any purpose the holder of the number of Common
Shares that may at any time be issuable on the exercise of the Rights
represented thereby, nor shall anything contained herein or in any Rights
Certificate be construed to confer upon the holder of any Rights Certificate, as
such, any of the rights of a shareholder of the Company or any right to vote for
the election of directors or upon any matter submitted to shareholders at any
meeting thereof, or to give or withhold consent to any action of the Company, or
to receive notice of meetings or other actions affecting shareholders (except as
provided in Section 24 hereof), or to receive distributions or subscription
rights, or otherwise, until the Right or Rights evidenced by such Rights
Certificate shall have been exercised in accordance with the provisions hereof.

         Section 18. Concerning the Rights Agent.

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

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

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

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

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

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

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

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

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

                                       22
<PAGE>   26

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

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

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

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

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

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

                                       23
<PAGE>   27

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

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

         Section 21. Change of Rights Agent. The Rights Agent or any successor
Rights Agent may resign and be discharged from its duties under this Agreement
upon thirty (30) days' notice in writing mailed to the Company, and to each
transfer agent of the Common Shares, by registered or certified mail, and to the
holders of the Rights Certificates by first-class mail. The Company may remove
the Rights Agent or any successor Rights Agent upon thirty (30) days' notice in
writing, mailed to the Rights Agent or successor Rights Agent, as the case may
be, and to each transfer agent of the Common Shares, by registered or certified
mail, and to the holders of the Rights Certificates by first-class mail. If the
Rights Agent shall resign or be removed or shall otherwise become incapable of
acting, the Company shall appoint a successor to the Rights Agent. If the
Company shall fail to make such appointment within a period of thirty (30) days
after giving notice of such removal or after it has been notified in writing of
such resignation or incapacity by the resigning or incapacitated Rights Agent or
by the holder of a Rights Certificate (who shall, with such notice, submit his
Rights Certificate for inspection by the Company), then any registered holder of
any Rights Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent. Any successor Rights Agent, whether appointed
by the Company or by such a court, shall be a corporation organized and doing
business under the laws of the United States or of the State of New York (or of
any other state of the United States so long as such corporation is authorized
to do business as a banking institution in the State of New York), in good
standing, having a principal office in the State of New York, which is
authorized under such laws to exercise corporate trust powers and is subject to
supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $100,000,000. After appointment, the successor Rights Agent shall be
vested with the same power, rights, duties and responsibilities as if it had
been originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment, the Company shall file notice
thereof in writing with the predecessor Rights Agent and each transfer agent of
the Common Shares, and mail a notice thereof in writing to the registered
holders of the Rights Certificates. Failure to give any notice provided for in
this Section 21, however, or any defect therein, shall not affect the legality
or validity of the resignation or removal of the Rights Agent or the appointment
of the successor Rights Agent, as the case may be.

         Section 22. Issuance of New Rights Certificates. Notwithstanding any of
the provisions of this Agreement or of the Rights to the contrary, the Company
may, at its option, issue new Rights

                                       24
<PAGE>   28

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

         Section 23. Redemption and Termination.

               (a) The Board of Directors of the Company may, at its option, at
any time prior to the earlier of (i) the close of business on the fifteenth
calendar day following the Share Acquisition Date, or (ii) the Final Expiration
Date, redeem all but not less than all the then-outstanding Rights at a
redemption price of $.01 per Right in cash, or by delivery of or exchange for
Common Shares (including fractional shares) or other consideration (including
but not limited to depository units representing Common Shares or fractions
thereof) deemed in good faith to have a fair market value equal to $.01 per
Right by the Board of Directors, as such amount may be appropriately adjusted to
reflect any stock split, distribution of member interests or similar transaction
occurring after the date hereof (such redemption price being hereinafter
referred to as the "Redemption Price"); provided further, however, that if,
following the occurrence of a Share Acquisition Date and following the
expiration of the right of redemption hereunder but prior to any Triggering
Event, (i) a Person who is an Acquiring Person shall have transferred or
otherwise disposed of a number of Common Shares in one transaction or series of
transactions, not directly or indirectly involving the Company or any of its
Subsidiaries, that did not result in the occurrence of a Triggering Event such
that such Person is thereafter a Beneficial Owner of 10% or less of the
outstanding Common Shares, and (ii) there are no other Persons, immediately
following the occurrence of the event described in clause (i), who are Acquiring
Persons, then the right of redemption shall be reinstated and thereafter be
subject to the provisions of this Section 23. Notwithstanding anything contained
in this Agreement to the contrary, the Rights shall not be exercisable after the
first occurrence of a Section 11(a)(ii) Event until such time as the Company's
right of redemption hereunder has expired. The Company may, at its option, pay
the Redemption Price in cash, Common Shares (based on the "current market
price", as defined in Section 11(d) hereof, of the Common Shares at the time of
redemption) or any other form of consideration deemed appropriate by the Board
of Directors.

               (b) Immediately upon the action of the Board of Directors of the
Company ordering the redemption of the Rights, evidence of which shall have been
filed with the Rights Agent and without any further action and without any
notice, the right to exercise the Rights will terminate and the only right
thereafter of the holders of Rights shall be to receive the Redemption Price for

                                       25
<PAGE>   29

each Right so held. Promptly after the action of the Board of Directors ordering
the redemption of the Rights, the Company shall give notice of such redemption
to the Rights Agent and the holders of the then outstanding Rights by mailing
such notice to all such holders at each holder's last address as it appears upon
the registry books of the Rights Agent or, prior to the Distribution Date, on
the registry books of the Transfer Agent for the Common Shares. Any notice which
is mailed in the manner herein provided shall be deemed given, whether or not
the holder receives the notice. Each such notice of redemption will state the
method by which the payment of the Redemption Price will be made.

         Section 24. Notice of Certain Events.

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

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

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

Subject to the provisions of Section 21, any notice or demand authorized by this
Agreement to be given or made by the Company or by the holder of any Rights
Certificate to or on the Rights Agent shall be sufficiently given or made if
sent by first-class mail, postage prepaid, addressed (until another address is

                           ---------------

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

         Section 26. Supplements and Amendments. Prior to the Distribution Date,
the Company and the Rights Agent shall, if the Company so directs, supplement or
amend any provision of this Agreement without the approval of any holders of
certificates representing Common Shares. From and after the Distribution Date
and subject to the penultimate sentence of this Section 26, the Company and the
Rights Agent shall, if the Company so directs, supplement or amend this
Agreement without the approval of any holders of Rights Certificates (i) to cure
any ambiguity, (ii) to correct or supplement any provision contained herein that
may be defective or inconsistent with any other provisions herein, (iii) to
shorten or lengthen any time period hereunder, or (iv) to change or supplement
the provisions hereunder in any manner that the Company may deem necessary or
desirable and that shall not adversely affect the interests of the holders of
Rights Certificates (other than an Acquiring Person or an Affiliate or Associate
of an Acquiring Person); provided, this Agreement may not be supplemented or
amended to lengthen, pursuant to clause (iii) of this sentence, (A) a time
period relating to when the Rights may be redeemed at such time as the Rights
are not then redeemable, or (B) any other time period unless such lengthening is
for the purpose of protecting, enhancing or clarifying the rights of, and/or the
benefits to, the holders of Rights. Upon the delivery of a certificate from an
appropriate officer of the Company that states that the proposed supplement or
amendment is in compliance with the terms of this Section 26, the Rights Agent
shall execute such supplement or amendment. Notwithstanding anything contained
in this Agreement to the contrary, from and after the Distribution Date, no
supplement or amendment shall be made that changes Section 23, this Section 26,
the Redemption Price, the Final Expiration Date, the Purchase Price or the
number of Common Shares for which a Right is exercisable. Prior to the
Distribution

                                       27
<PAGE>   31

Date, the interests of the holders of Rights shall be deemed coincident with the
interests of the holders of Common Shares.

         Section 27. Successors. All the covenants and provisions of this
Agreement by or for the benefit of the Company or the Rights Agent shall bind
and inure to the benefit of their respective successors and assigns hereunder.

         Section 28. Determinations and Actions by the Board of Directors, etc.
For all purposes of this Agreement, any calculation of the number of Common
Shares outstanding at any particular time, including for purposes of determining
the particular percentage of such outstanding Common Shares of which any Person
is the Beneficial Owner, shall be made in accordance with the last sentence of
Rule 13d-3(d)(1)(i) of the General Rules and Regulations under the Exchange Act.
The Board of Directors of the Company shall have the exclusive power and
authority to administer this Agreement and to exercise all rights and powers
specifically granted to the Board or to the Company, or as may be necessary or
advisable in the administration of this Agreement, including, without
limitation, the right and power to (i) interpret the provisions of this
Agreement, and (ii) make all determinations deemed necessary or advisable for
the administration of this Agreement (including a determination to redeem or not
redeem the Rights or to amend the Agreement). All such actions, calculations,
interpretations and determinations (including, for purposes of clause (y) below,
all omissions with respect to the foregoing) which are done or made by the Board
of Directors in good faith, shall (x) be final, conclusive and binding on the
Company, the Rights Agent, the holders of the Rights and other parties, and (y)
not subject the Board of Directors to any liability to the holders of the
Rights.

         Section 29. Benefits of this Agreement. Nothing in this Agreement shall
be construed to give to any Person other than the Company, the Rights Agent and
the registered holders of the Rights Certificates (and, prior to the
Distribution Date, registered holders of the Common Shares) any legal or
equitable right, remedy or claim under this Agreement; but this Agreement shall
be for the sole and exclusive benefit of the Company, the Rights Agent and the
registered holders of the Rights Certificates (and, prior to the Distribution
Date, registered holders of the Common Shares).

         Section 30. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated;
provided, however, that notwithstanding anything in this Agreement to the
contrary, if any such term, provision, covenant or restriction is held by such
court or authority to be invalid, void or unenforceable and the Board of
Directors of the Company determines in its good faith judgment that severing the
invalid language from this Agreement would adversely affect the purpose or
effect of this Agreement, the right of redemption set forth in Section 23 hereof
shall be reinstated and shall not expire until the close of business on the
tenth day following the date of such determination by the Board of Directors.

         Section 31. Governing Law. This Agreement, each Right and each Rights
Certificate issued hereunder shall be deemed to be a contract made under the
laws of the State of Delaware and for all purposes shall be governed by and
construed in accordance with the laws of such State applicable to contracts made
and to be performed entirely within such State, except that the rights and
obligations of the Rights Agent shall be governed by the laws of the State of
Texas.

         Section 32. Counterparts. This Agreement may be executed in any number
of counterparts and each of such counterparts shall for all purposes be deemed
to be an original, and all such counterparts shall together constitute but one
and the same instrument.

         Section 33. Descriptive Headings. Descriptive headings of the several
Sections of this Agreement are inserted for convenience only and shall not
control or affect the meaning or construction of any of the provisions hereof.

by this Rights Certificate (and the number of shares that may be purchased upon
exercise thereof) set forth above, and the Purchase Price per share set forth
above, are the number and Purchase Price as of __________, 2001, based on the
Common Shares as constituted at such date.

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

         As provided in the Rights Agreement, the Purchase Price and the number
and kind of Common Shares that may be purchased upon the exercise of the Rights
evidenced by this Rights Certificate are subject to modification and adjustment
upon the happening of certain events, including Triggering Events.

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

         This Rights Certificate, with or without other Rights Certificates,
upon surrender at the principal office or offices of the Rights Agent designated
for such purpose, may be exchanged for another Rights Certificate or Rights
Certificates of like tenor and date evidencing Rights entitling the holder to
purchase a like aggregate number of Common Shares as the Rights evidenced by the
Rights Certificate or Rights Certificates surrendered shall have entitled such
holder to purchase. If this Rights Certificate shall be exercised in part, the
holder shall be entitled to receive upon surrender hereof another Rights
Certificate or Rights Certificates for the number of whole Rights not exercised.

         Subject to the provisions of the Rights Agreement, the Rights evidenced
by this Certificate may be redeemed by the Company at its option at a redemption
price of $.01 per Right at any time prior to the earlier of the close of
business on (i) the fifteenth day following the Share Acquisition Date (as such
time period may be extended pursuant to the Rights Agreement), and (ii) the
Final Expiration Date. After the expiration of the redemption period, the
Company's right of redemption may be reinstated if an Acquiring Person reduces
his beneficial ownership to 10% or less of the outstanding Common Shares in a
transaction or series of transactions not involving the Company.

         No fractional Common Shares will be issued upon the exercise of any
Right or Rights evidenced hereby, but in lieu thereof a cash payment will be
made, as provided in the Rights Agreement.

         No holder of this Rights Certificate shall be entitled to vote or
receive distributions or be deemed for any purpose the holder of Common Shares
that may at any time be issuable on the exercise hereof, nor shall anything
contained in the Rights Agreement or herein be construed to confer upon the
holder hereof, as such, any of the rights of a shareholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
shareholders at any meeting thereof, or to give or withhold consent to any
action, or, to receive notice of meetings or other actions affecting
shareholders (except as provided in the Rights Agreement), or to receive

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