                  ------------
 
               The Board of Directors of BCP Management Inc., as the general
partner of the Partnership (the "General Partner"), has authorized the issuance
                                 ---------------
and declared a distribution of (i) one common unit purchase right (a "Right")
                                                                      -----
for each Unit (as hereinafter defined) of the Partnership outstanding as of the
close of business (as defined below) on April 21, 1997 (the "Record Date") and
                                                             -----------
(ii) such number of Rights as shall most closely approximate 1/99th of the
number of Units outstanding on the Record Date in respect of the General
Partner's interest in the Partnership as of the Record Date, each Right
representing the right to purchase one Unit (subject to adjustment) upon the
terms and subject to the conditions herein set forth, and has further authorized
and directed the issuance of (i) one Right (subject to adjustment as provided
herein) with respect to each Unit that shall become outstanding between the
Record Date and the earliest of the Distribution Date, the Redemption Date and
the Final Expiration Date (as such terms are hereinafter defined) and (ii) such
number of Rights (subject to adjustment as provided herein) as shall most
closely approximate 1/99th of the number of Rights issued as a result of the
Units that shall become outstanding between such dates pursuant to the
immediately preceding clause (i) in respect of additional contributions to the
Partnership by the General Partner; provided, however, that Rights may be issued
                                    --------  -------
with respect to Units that shall become outstanding after the Distribution Date
and prior to the Redemption Date and the Final Expiration Date in accordance
with Section 22.

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

 
                                                                               2


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

                      (a) "Acquiring Person" shall mean any Person (as such term
                           ----------------
        is hereinafter defined) who or which shall be the Beneficial Owner (as
        such term is hereinafter defined) of 15% or more of the Units then
        outstanding, but shall not include an Exempt Person (as such term is
        hereinafter defined); provided, however, that if the General Partner
                              --------  -------
        determines in good faith that a Person who would otherwise be an
        "Acquiring Person" has become such inadvertently (including, without
        limitation, because (i) such Person was unaware that it beneficially
        owned a percentage of Units that would otherwise cause such Person to be
        a "Acquiring Person" or (ii) such Person was aware of the extent of its
        Beneficial Ownership of the Units but had no actual knowledge of the
        consequences of such Beneficial Ownership under this Rights Agreement)
        and without any intention of changing or influencing control of the
        Partnership, and such Person, as promptly as practicable divested or
        divests himself or itself of Beneficial Ownership of a sufficient number
        of Units so that such Person would no longer be an Acquiring Person,
        then such Person shall not be deemed to be or to have become an
        "Acquiring Person" for any purposes of this Agreement. Notwithstanding
        the foregoing, (i) if a Person would otherwise be deemed an Acquiring
        Person upon the adoption of this Agreement, such Person will not be
        deemed an Acquiring Person for any purposes of this Agreement unless and
        until such Person acquires Beneficial Ownership of any additional Units
        after the adoption of this Agreement, unless upon the consummation of
        the acquisition of such additional Units such Person does not
        beneficially own 15% or more of the Units then outstanding, and (ii) no
        Person shall become an "Acquiring Person" as the result of an

 
                                                                               3

        acquisition of Units by the Partnership which, by reducing the number of
        Units outstanding, increases the proportionate number of Units
        beneficially owned by such Person to 15% or more of the Units then
        outstanding, provided, however, that if a Person shall become the
                     --------  -------
        Beneficial Owner of 15% or more of the Units then outstanding by reason
        of such Unit acquisitions by the Partnership and thereafter become the
        Beneficial Owner of any additional Units, then such Person shall be
        deemed to be an "Acquiring Person" unless upon the consummation of the
        acquisition of such additional Units such Person does not own 15% or
        more of the Units then outstanding. The phrase "then outstanding", when
                                                        ----------------
        used with reference to a Person's Beneficial Ownership of securities
        (including without limitation Units) of the Partnership, shall mean the
        number of such securities then issued and outstanding together with the
        number of such securities not then actually issued and outstanding which
        such Person would be deemed to own beneficially hereunder.

                      (b) "Affiliate" and "Associate" shall have the respective
                           ---------       ---------
        meanings ascribed to such terms in Rule 12b-2 of the General Rules and
        Regulations under the Securities Exchange Act of 1934, as amended (the

Act) by the Partnership or an Acquiring Person that an Acquiring Person has
become such or such earlier date as the General Partner shall become aware of
the existence of an Acquiring Person.

                      (ab)    "Unit equivalent" shall have the meaning set forth
                               ---------------
in Section 11(a)(ii).

                       Any determination required to be made by the General
Partner of the Partnership for purposes of applying the definitions contained in
this Section 1 shall be made solely by the General Partner in its good faith
judgment, which determination shall be binding on the Rights Agent and the
holders of the Rights.

 
                                                                               8




               Section 2. Appointment of Rights Agent. The Partnership
                          ---------------------------
hereby appoints the Rights Agent to act as agent for the Partnership and the
holders of the Rights (who, (in addition to the General Partner) shall prior to
the Distribution Date also be the holders of Units in accordance with Section 3
hereof) in accordance with the terms and conditions hereof, and the Rights Agent
hereby accepts such appointment. The Partnership may from time to time appoint
such co-Rights Agents as it may deem necessary or desirable.

               Section 3. Issue of Right Certificates. (a) Until the earlier of
                          ---------------------------
(i) the tenth day after the Unit Acquisition Date or (ii) the tenth business day
(or such later date as may be determined by action of the General Partner prior
to such time as any Person becomes an Acquiring Person) after the date of the
commencement by any Person (other than an Exempt Person) of, or of the first
public announcement of the intention of such Person (other than an Exempt
Person) to commence a tender or exchange offer the consummation of which would
result in any Person becoming the Beneficial Owner of Units aggregating 15% or
more of the Units then outstanding (including any such date which is after the
date of this Agreement and prior to the issuance of the Rights; the earlier of
such dates being herein referred to as the "Distribution Date"), (x) the Rights
                                            -----------------
(other than those held by the General Partner) will be evidenced (subject to the
provisions of Section 3(b) hereof) by the certificates for Units registered in
the names of the holders thereof and not by separate Right certificates, and (y)
the Rights will be transferable only in connection with the transfer of Units
(or the transfer of the General Partner's interest in the Partnership). As soon
as practicable after the Distribution Date, the Partnership will prepare and
execute, the Rights Agent will countersign, and the Partnership will send or
cause to be sent (and the Rights Agent will, if requested, send) by first-class,
insured, postage-prepaid mail, to (i) each record holder of Units as of the
close of business on the 

 
                                                                               9
Distribution Date (other than any Acquiring Person or any Associate or Affiliate
of an Acquiring Person), at the address of such holder shown on the records of
the Partnership, a Right Certificate, in substantially the form of Exhibit A
hereto (a "Right Certificate"), evidencing one Right (subject to adjustment as
           -----------------
provided herein) for each Unit so held and (ii) to the General Partner, at its
address shown on the records of the Partnership, a Right Certificate evidencing
the Rights (subject to adjustment as provided herein) in respect of the General
Partner's interest in the Partnership. As of the Distribution Date, the Rights
will be evidenced solely by such Right Certificates. Notwithstanding anything in
this Agreement to the contrary, a Distribution Date shall not be deemed to have
occurred solely as the result of the approval, execution or delivery of the
Agreement and Plan of Conversion or the consummation of the Transactions (as
defined in the Agreement and Plan of Conversion) contemplated thereby. 
Nothwithstanding anything to the contrary in this Agreement or the Partnership 
Agreement to the contrary, a subdivision or combination of the Units for 
purposes of Section 4.11(a) of the Partnership Agreement shall include the 
distribution of the Rights and any issuance of Units or any other securities of 
the Partnership upon the exericise of the Rights pursuant to this 
Agreement.

                      (b) On the Record Date, or as soon as practicable
thereafter, the Partnership will send a copy of a Summary of Rights to Purchase
Units, in substantially the form of Exhibit B hereto (the "Summary of Rights"),
                                                           -----------------
by first-class, postage-prepaid mail, to each record holder of Units as of the
close of business on the Record Date (other than any Acquiring Person or any
Associate or Affiliate of any Acquiring Person), at the address of such holder
shown on the records of the Partnership. With respect to certificates for Units
outstanding as of the Record Date, until the Distribution Date, the Rights will
be evidenced by such certificates registered in the names of the holders thereof
together with the Summary of Rights. Until the Distribution Date (or the earlier
of the Redemption Date or the Final Expiration Date), the surrender for transfer
of any certificate for Units outstanding on the Record Date, with or without a
copy of the Summary of Rights, shall also constitute the transfer of the Rights
associated with the Units represented thereby.

 
                                                                              10

                      (c) Certificates issued for Units (including, without
limitation, upon transfer of outstanding Units, disposition of Units out of
Units held in treasury or issuance or reissuance of Units out of authorized but
unissued Units) after the Record Date but prior to the earliest of the
Distribution Date, the Redemption Date or the Final Expiration Date shall have
impressed on, printed on, written on or otherwise affixed to them the following
legend:

               This certificate also evidences and entitles the holder hereof to
               certain rights as set forth in a Rights Agreement between Borden
               Chemicals and Plastics Limited Partnership and Harris Trust and
               Savings Bank dated as of April 8, 1997 as the same may be amended
               from time to time (the "Rights Agreement"), the terms of which
                                       ----------------
               are hereby incorporated herein by reference and a copy of which
               is on file at the principal executive offices of Borden Chemicals
               and Plastics Limited Partnership. 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. Borden Chemicals and Plastics Limited Partnership
               will mail to the holder of this certificate a copy of the Rights
               Agreement without charge after receipt of a written request
               therefor. Under certain circumstances, as set forth in the Rights
                         -------------------------------------------------------
               Agreement, Rights owned by or transferred to any Person who
               -----------------------------------------------------------
               becomes an Acquiring Person (as defined in the Rights Agreement)
               ----------------------------------------------------------------
               and certain transferees thereof will become null and void and
               -------------------------------------------------------------
               will no longer be transferable.
               ------------------------------

With respect to such certificates containing the foregoing legend, until the
Distribution Date, the Rights associated with the Units represented by such
certificates shall be evidenced by such certificates alone, and the surrender
for transfer of any such certificate, except as otherwise provided herein, shall
also constitute the transfer of the Rights associated with the Units represented
thereby. In the event that the Partnership purchases or otherwise acquires any
Units after the Record Date but prior to the Distribution Date, any Rights
associated with such Units shall be deemed cancelled and retired so that the
Partnership shall not be entitled to exercise any Rights associated with the
Units which are no longer outstanding.

 
                                                                              11

               Notwithstanding this paragraph (c), the omission of a legend
shall not affect the enforceability of any part of this Agreement or the rights
of any holder of the Rights.

               Section 4. Form of Right Certificates. The Right Certificates
                          --------------------------
(and the forms of election to purchase Units and of assignment to be printed on
the reverse thereof) shall 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 Partnership may deem
appropriate and as are not inconsistent with the provisions of this Agreement,
or as may be required to comply with any applicable law or with any rule or
regulation made pursuant thereto or with any rule or regulation of the New York
Stock Exchange or of any other stock exchange or automated quotation system on
which the Rights may from time to time be listed, or to conform to usage.
Subject to the provisions of Sections 11, 13 and 22 hereof, the Right
Certificates shall entitle the holders thereof to purchase such number of Units
as shall be set forth therein at the price per Unit set forth therein (the
"Purchase Price"), but the number of such Units and the Purchase Price shall be
 --------------
subject to adjustment as provided herein.

               Section 5. Countersignature and Registration. (a) The Right
                          ---------------------------------
Certificates shall be executed on behalf of the Partnership by the Chairman of
the Board of Directors, the President, any Vice President, the Treasurer or the
Controller of the General Partner, either manually or by facsimile signature.
The Right Certificates shall be manually countersigned by the Rights Agent and
shall not be valid for any purpose unless countersigned. In case any officer of
the General Partner who shall have signed any of the Right Certificates shall
cease to be such officer of the General Partner before countersignature by the
Rights Agent and issuance and delivery by the Partnership, such Right
Certificates, nevertheless, may be countersigned by the Rights Agent and issued
and delivered by the Partnership with the same force and effect as 

 
                                                                              12

though the Person who signed such Right Certificates had not ceased to be such
officer of the General Partner; and any Right Certificate may be signed on
behalf of the Partnership by any Person who, at the actual date of the execution
of such Right Certificate, shall be a proper officer of the General Partner to
sign such Right Certificate, although at the date of the execution of this
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 an office or agency designated for such purpose, books
for registration and transfer of the Right Certificates issued hereunder. Such
books shall show the names and addresses of the respective holders of the Right
Certificates, the number of Rights evidenced on its face by each of the Right
Certificates and the date of each of the Right Certificates.

               Section 6. Transfer, Split Up, Combination and Exchange of Right
                          -----------------------------------------------------
Certificates; Mutilated, Destroyed, Lost or Stolen Right Certificates. (a)
- ---------------------------------------------------------------------
Subject to the provisions of Sections 7(e), 11(a)(ii) and 14 hereof, at any time
after the close of business on the Distribution Date, and prior to the close of
business on the earlier of the Redemption Date or the Final Expiration Date, any
Right Certificate or Right Certificates may be transferred, split up, combined
or exchanged for another Right Certificate or Right Certificates, entitling the
registered holder to purchase a like number of Units as the Right Certificate or
Right Certificates surrendered then entitled such holder to purchase. Any
registered holder desiring to transfer, split up, combine or exchange any Right
Certificate or Right Certificates shall make such request in writing delivered
to the Rights Agent, and shall surrender the Right Certificate or Right
Certificates to be transferred, split up, combined or exchanged at the office or
agency of the Rights Agent designated for such purpose. Thereupon the Rights
Agent shall countersign and deliver to the Person entitled thereto a Right
Certificate or Right Certificates, as the case may be, as so requested. The
Partnership may 

 
                                                                              13

require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer, split up, combination or
exchange of Right Certificates.

                      (b) Subject to the provisions of Section 11(a)(ii) hereof,
at any time after the Distribution Date and prior to the close of business on
the earlier of the Redemption Date or the Final Expiration Date, upon receipt by
the Partnership and the Rights Agent of evidence reasonably satisfactory to them
of the loss, theft, destruction or mutilation of a Right Certificate, and, in
case of loss, theft or destruction, delivery of an indemnity bond reasonably
satisfactory to them, and, at the Partnership's request, reimbursement to the
Partnership and the Rights Agent of all reasonable expenses incidental thereto,
and upon surrender to the Rights Agent and cancellation of the Right Certificate
if mutilated, the Partnership will make and deliver a new Right Certificate of
like tenor to the Rights Agent for delivery to the registered holder in lieu of
the Right Certificate so lost, stolen, destroyed or mutilated.

               Section 7. Exercise of Rights, Purchase Price; Expiration Date of
                          ------------------------------------------------------
Rights. (a) Except as otherwise provided herein, the Rights shall become

exercisable on the Distribution Date, and thereafter the registered holder of
any Right Certificate may, subject to Section 11(a)(ii) hereof and except as
otherwise provided herein, exercise the Rights evidenced thereby in whole or in
part upon surrender of the Right Certificate, with the form of election to
purchase on the reverse side thereof duly executed, to the Rights Agent at the
office or agency of the Rights Agent designated for such purpose, together with
payment of the Purchase Price for the Units as to which the Rights are
exercised, at any time which is both after the Distribution Date and prior to
the earliest of (i) the close of business on April 8, 2007 (the "Final
                                                                 -----
Expiration Date"), (ii) the time at which the Rights are redeemed as provided in
- ---------------
Section 23 hereof (the "Redemption Date"), (iii) the time at which such Rights
                        ---------------
are exchanged as provided in Section 

 
                                                                              14

24 hereof and (iv) immediately prior to the Effective Time of the Merger (as
defined in the Agreement and Plan of Conversion).

                      (b)     The Purchase Price shall be initially $21.00 for
each Unit purchasable upon the exercise of a Right. The Purchase Price and the
number of Units or other securities or property to be acquired upon exercise of
a Right shall be subject to adjustment from time to time as provided in Sections
11 and 13 hereof and shall be payable in lawful money of the United States of
America in accordance with paragraph (c) of this Section 7.

                      (c)     Except as otherwise provided herein, upon receipt
of a Right Certificate representing exercisable Rights, with the form of
election to purchase duly executed, accompanied by payment of the aggregate
Purchase Price for the Units to be purchased and an amount equal to any
applicable transfer tax required to be paid by the holder of such Right
Certificate in accordance with Section 9 hereof, in cash or by certified check,
cashier's check or money order payable to the order of the Partnership, the
Rights Agent shall thereupon promptly (i) (A) requisition from any transfer
agent of Units certificates for the number of Units to be purchased and the
Partnership hereby irrevocably authorizes its transfer agent to comply with all
such requests, or (B) requisition from the depositary agent depositary receipts
representing interests in such number of units as are to be purchased (in which
case certificates for the Units represented by such receipts shall be deposited
by the transfer agent with the depositary agent, and the Partnership hereby
directs the depositary agent to comply with such request), (ii) when
appropriate, requisition from the Partnership the amount of cash to be paid in
lieu of issuance of fractional Units in accordance with Section 14 hereof, (iii)
promptly after receipt of such certificates or depositary receipts, cause the
same to be delivered to or upon the order of the registered holder of such Right
Certificate, registered in such name or names as may be 

 
                                                                              15

designated by such holder and (iv) when appropriate, after receipt, promptly
deliver such cash to or upon the order of the registered holder of such Right
Certificate.

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

                      (e) Notwithstanding anything in this Agreement to the
contrary, neither the Rights Agent nor the Partnership shall be obligated to
undertake any action with respect to a registered holder of Rights upon the
occurrence of any purported transfer or exercise of Rights pursuant to Section 6
hereof or this Section 7 unless such registered holder shall have (i) completed
and signed the certificate contained in the form of assignment or election to
purchase set forth on the reverse side of the Right Certificate surrendered for
such transfer or exercise and (ii) provided such additional evidence of the
identity of the Beneficial Owner (or former Beneficial Owner) thereof as the
Partnership shall reasonably request.

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

 
                                                                              16

The Rights Agent shall deliver all cancelled Right Certificates to the
Partnership, or shall, at the written request of the Partnership, destroy such
cancelled Right Certificates, and in such case shall deliver a certificate of
destruction thereof to the Partnership.

               Section 9. Availability of Units. (a) The Partnership covenants
                          ---------------------
and agrees that it will cause to be authorized and kept available out of its
authorized and unissued Units or out of Units held in its treasury, the number
of Units that will be sufficient from time to time to permit the exercise in
full of all outstanding Rights.

                      (b) So long as the Units (and, following the time that a
Person becomes an Acquiring Person, any other securities issuable upon the
exercise of Rights) may be listed or admitted to trading on the New York Stock
Exchange or listed on any other national securities exchange or quotation
system, the Partnership shall use its best efforts to cause, from and after such
time as the Rights become exercisable, all Units (or other securities) issued or
reserved for such issuance pursuant to this Agreement to be listed or admitted
to trading on the New York Stock Exchange or listed on any other exchange or
quotation system upon official notice of issuance upon such exercise.

                      (c) From and after such time as the Rights become
exercisable, the Partnership shall use its best efforts, if then necessary to
permit the issuance of Units (and following the time that a Person first becomes
an Acquiring Person, any other securities) upon the exercise of Rights, to
register and qualify such Units (and following the time that a Person first
becomes an Acquiring Person, any other securities) under the Securities Act and
any applicable state securities or "Blue Sky" laws (to the extent exemptions
therefrom are not available), cause such registration statement and
qualifications to become effective as soon as possible after such filing and
keep such registration and qualifications effective until the earlier of the
date as of which the 

 
                                                                              17

Rights are no longer exercisable for such securities and the Final Expiration
Date. The Partnership may temporarily suspend, for a period of time not to
exceed 90 days, the exercisability of the Rights in order to prepare and file a
registration statement under the Securities Act and permit it to become
effective. Upon any such suspension, the Partnership shall issue a public
announcement stating that the exercisability of the Rights has been temporarily
suspended, as well as a public announcement at such time as the suspension is no
longer in effect. Notwithstanding any provision of this Agreement to the
contrary, the Rights shall not be exercisable in any jurisdiction unless the
requisite qualification in such jurisdiction shall have been obtained and until
a registration statement under the Securities Act (if required) shall have been
declared effective.

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

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

 
                                                                              18

such tax being payable by that holder of such Right Certificate at the time of
surrender) or until it has been established to the Partnership's reasonable
satisfaction that no such tax is due.

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

               Section 11. Adjustment of Purchase Price, Number of Units and
                           -------------------------------------------------
Number of Rights. The Purchase Price, the number of Units or other securities or
- ----------------
property purchasable upon exercise of each Right and the number of Rights
outstanding are subject to adjustment from time to time as provided in this
Section 11. 

               (a) (i) In the event the Partnership shall at any time after the
               date of this Agreement (A) make a distribution on the Units
               payable in Units, (B) subdivide or split the outstanding Units,
               (C) combine the outstanding Units into a smaller number of Units

               reclassification of the Units (including any such
               reclassification in connection with a consolidation or merger in
               which the Partnership is the continuing or surviving entity),
               except as otherwise provided in this Section 11(a), 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
               limited partnership interests (or other securities) issuable on
               such date, shall be proportionately adjusted so that the holder
               of any Right exercised after such time shall be entitled to
               receive the aggregate number and kind of limited partnership
               interests (or other securities) which, if such Right had been
               exercised immediately prior to such date and at a time when the
               transfer books of the Partnership were open, the holder would
               have owned upon such exercise and been entitled to receive by
               virtue of such distribution, subdivision, combination or
               reclassification.

                             (ii) Subject to Section 24 of this Agreement and
               except as otherwise provided in this Section 11(a)(ii), in the
               event any Person becomes an Acquiring Person, each holder of a
               Right shall thereafter have the right to receive, upon exercise
               thereof at a price equal to the then current Purchase Price
               multiplied by the number of Units for which a Right is then
               exercisable, in accordance with the terms of this Agreement, such
               number of Units as shall equal the result obtained by (x)
               multiplying the then current Purchase Price by the number of
               Units for which a Right is then exercisable and dividing that
               product by (y) 50% of the then current market price per Unit of
               the Units (determined pursuant to Section 11(d) hereof) on the
               date of the occurrence of such event; provided, however, that the

               exercise of a Right

               shall thereafter be subject to further adjustment as appropriate
               in accordance with Section 11(f) hereof. Notwithstanding anything
               in this Agreement to the contrary, however, from and after the
               time (the "invalidation time") when any Person first becomes an
                          -----------------
               Acquiring Person, any Rights that are beneficially owned by (x)
               any Acquiring Person (or any Affiliate or Associate of any
               Acquiring Person), (y) a transferee of any Acquiring Person (or
               any such Affiliate or Associate) who becomes a transferee after
               the invalidation time or (z) a transferee of any Acquiring Person
               (or any such Affiliate or Associate) who became a transferee
               prior to or concurrently with the invalidation time pursuant to
               either (I) a transfer from the Acquiring Person to holders of its
               equity securities or to any Person with whom it has any
               continuing agreement, arrangement or understanding regarding the
               transferred Rights or (II) a transfer which the Partnership has
               determined is part of a plan, arrangement or understanding which
               has the purpose or effect of avoiding the provisions of this
               paragraph, and subsequent transferees of such Persons, shall be
               void without any further action and any holder of such Rights
               shall thereafter have no rights whatsoever with respect to such
               Rights under any provision of this Agreement. The Partnership
               shall use all reasonable efforts to ensure that the provisions of
               this Section 11(a)(ii) are complied with, but shall have no
               liability to any holder of Right 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. From and after the invalidation time, no
               Right Certificate shall be issued pursuant to Section 3 or
               Section 6 hereof that represents Rights that are or have become
               void pursuant to the provisions of 

 
                                                                              21

               this paragraph, and any Right Certificate delivered to the Rights
               Agent that represents Rights that are or have become void
               pursuant to the provisions of this paragraph shall be cancelled.
               From and after the occurrence of an event specified in Section
               13(a) hereof, any Rights that theretofore have not been exercised
               pursuant to this Section 11(a)(ii) shall thereafter be
               exercisable only in accordance with Section 13 and not pursuant
               to this Section 11(a)(ii). In the event that there shall not be
               sufficient Units authorized but unissued to permit the exercise
               in full of the Rights in accordance with the foregoing
               subparagraphs (i) or (ii), the Partnership shall, to the extent
               permitted by applicable law and any material agreements then in
               effect to which the Partnership is a party (A) determine the
               excess of (1) the value of the Units issuable upon the exercise
               of a Right in accordance with the foregoing subparagraphs (i) and
               (ii) (the "Current Value") over (2) the then current Purchase
                          -------------
               Price multiplied by the number of Units for which a Right was
               exercisable immediately prior to the time that the Acquiring
               Person became such (such excess, the "Spread"), and (B) with
                                                     ------
               respect to each Right (other than Rights which have become void
               pursuant to Section 11(a)(ii)), make adequate provision to
               substitute for the Units issuable in accordance with subparagraph
               5(i) or (ii) upon exercise of the Right and payment of the
               applicable Purchase Price, (1) cash, (2) a reduction in the
               Purchase Price, (3) other equity securities of the Partnership
               (including, without limitation, limited partnership interests or
               fractions thereof which, by virtue of having distribution, voting
               and liquidation rights substantially comparable to those of the
               Units, are deemed in good faith by the Partnership to have
               substantially the same value as the Units

 
                                                                              22


               (such limited partnership interests or fractions thereof are
               hereinafter referred to as "Unit equivalents"), (4) debt
                                           ----------------
               securities of the Partnership, (5) other assets, or (6) any
               combination of the foregoing, having a value which, when added to
               the value of the Units actually issued upon exercise of such
               Right, shall have an aggregate value equal to the Current Value
               (less the amount of any reduction in the Purchase Price), where
               such aggregate value has been determined by the Partnership upon
               the advice of a nationally recognized investment banking firm
               selected in good faith by the General Partner of the Partnership;
               provided, however, if the Partnership shall not make adequate
               --------  -------
               provision to deliver value pursuant to clause (B) above within
               thirty (30) days following the date that the Acquiring Person
               became such (the "Section 11(a)(ii) Trigger Date"), then the
                                 ------------------------------
               Partnership shall be obligated to deliver, to the extent
               permitted by applicable law and any material agreements then in
               effect to which the Partnership is a party, upon the surrender
               for exercise of a Right and without requiring payment of the
               Purchase Price, Units (to the extent available), and then, if
               necessary, cash, which Units and/or cash have an aggregate value
               equal to the Spread. If, upon the date any Person becomes an
               Acquiring Person, the Partnership shall determine in good faith
               that it is likely that sufficient additional Units could be
               authorized for issuance upon exercise in full of the Rights,
               then, if the Partnership so elects, the thirty (30) day period
               set forth above may be extended to the extent necessary, but not
               more than ninety (90) days after the Section 11(a)(ii) Trigger
               Date, in order that the Partnership may seek approval from the
               holders of the Units for the authorization of such additional
               Units (such thirty (30) day period, as it may be extended, is
               herein called the

 
                                                                              23

               "Substitution Period"). To the extent that the Partnership
                -------------------
               determines that some action need be taken pursuant to the second
               and/or third sentence of this Section 11(a)(iii), the Partnership
               (x) shall provide, subject to Section 11(a)(ii) hereof and the
               last sentence of this Section 11(a)(iii) hereof, that such action
               shall apply uniformly to all outstanding Rights and (y) may
               suspend the exercisability of the Rights until the expiration of
               the Substitution Period in order to seek any authorization of
               additional Units and/or to decide the appropriate form of
               distribution to be made pursuant to such second sentence and to
               determine the value thereof. In the event of any such suspension,
               the Partnership shall issue a public announcement stating that
               the exercisability of the Rights has been temporarily suspended,
               as well as a public announcement at such time as the suspension
               is no longer in effect. For purposes of this Section 11(a)(iii),
               the value of the Units shall be the aggregate of the current
               market price per Unit for the Units (as determined pursuant to
               Section 11(d)(i)) on the Section 11(a)(ii) Trigger Date and the
               per unit or fractional value of any "Unit equivalent" shall be
               deemed to equal the current market price per Unit of the Units.
               The Partnership may, but shall not be required to, establish
               procedures to allocate the right to receive Units upon the
               exercise of the Rights among holders of Rights pursuant to this
               Section 11(a)(iii). 

               (b) In case the Partnership shall fix a record date for the
        issuance of rights, options or warrants to all holders of Units
        entitling them (for a period expiring within 45 calendar days after such
        record date) to subscribe for or purchase Units or securities
        convertible into Units or Unit equivalents at a price per Unit or Unit
        equivalent (or having 

 
                                                                              24

        a conversion price per Unit, if a security convertible into Units or
        Unit equivalents) less than the then current market price per Unit of
        the Units (determined pursuant to Section 11(d) hereof) on such record
        date, the Purchase Price to be in effect after such record date shall be
        determined by multiplying the Purchase Price in effect immediately prior
        to such record date by a fraction, the numerator of which shall be the
        number of Units and Unit equivalents outstanding on such record date
        plus the number of Units and Unit equivalents which the aggregate
        offering price of the total number of Units and/or Unit equivalents so
        to be offered (and/or the aggregate initial conversion price of the
        convertible securities so to be offered) would purchase at such current
        market price, and the denominator of which shall be the number of Units
        and Unit equivalents outstanding on such record date plus the number of
        additional Units and/or Unit equivalents to be offered for subscription
        or purchase (or into which the convertible securities so to be offered
        are initially convertible). In case such subscription price may be paid
        in a consideration part or all of which shall be in a form other than
        cash, the value of such consideration shall be as determined in good
        faith by the General Partner of the Partnership, whose determination
        shall be described in a statement filed with the Rights Agent. Units and
        Unit equivalents owned by or held for the account of the Partnership
        shall not be deemed outstanding for the purpose of any such computation.
        Such adjustment shall be made successively whenever such a record date
        is fixed; and in the event that such rights, options or warrants are not
        so issued, the Purchase Price shall be adjusted to be the Purchase Price
        which would then be in effect if such record date had not been fixed.

 
                                                                              25

                      (c) In case the Partnership shall fix a record date for
        the making of a distribution to all holders of Units (including any such
        distribution made in connection with a consolidation or merger in which
        the Partnership is the continuing or surviving entity) of evidences of
        indebtedness or assets (other than a regular quarterly cash distribution
        or a distribution payable in Units) 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 then
        current market price per Unit (determined pursuant to Section 11(d)
        hereof) on such record date, less the fair market value (as determined
        in good faith by the General Partner of the Partnership, whose
        determination shall be described in a statement filed with the Rights
        Agent) of the portion of the assets or evidences of indebtedness so to
        be distributed or of such subscription rights or warrants applicable to
        one Unit, and the denominator of which shall be such current market
        price per Unit (determined pursuant to Section 11(d) hereof) of the
        Units. Such adjustments shall be made successively whenever such a
        record date is fixed; and in the event that such distribution is not so
        made, the Purchase Price shall again be adjusted to be the Purchase
        Price which would then be in effect if such record date had not been
        fixed.

               (d) (i) Except as otherwise provided herein, for the purpose of
        any computation hereunder, the "current market price" of any security (a
                                        --------------------
        "Security" for the purpose of this Section 11(d)(i)) on any date shall
        be deemed to be the average of the daily closing prices per unit or
        share, as applicable, of such Security for the 30 consecutive Trading
        Days (as such term is hereinafter defined) immediately prior to such
        date; provided, however, that 
              --------  -------

 
                                                                              26

        in the event that the current market price per unit or share of the
        Security is determined during a period following the announcement by the
        issuer of such Security of (A) a distribution on such Security payable
        in units or shares of such Security or securities convertible into such
        units or shares, or (B) any subdivision, combination or reclassification
        of such Security, and prior to the expiration of 30 Trading Days after
        the ex-dividend or ex-distribution date for such dividend or
        distribution, or the record date for such subdivision, combination or
        reclassification, then, and in each such case, the current market price
        shall be appropriately adjusted to reflect the current market price per
        unit or share equivalent of such Security. The closing price for each
        day shall be the last sale price, regular way, or, in case no such sale
        takes place on such day, the average of the closing bid and asked
        prices, regular way, in either case as reported by the principal
        consolidated transaction reporting system with respect to securities
        listed or admitted to trading on the New York Stock Exchange or, if the
        Security is not listed or admitted to trading on the New York Stock
        Exchange, as reported in the principal consolidated transaction
        reporting system with respect to securities listed on the principal
        national securities exchange on which the Security is listed or admitted
        to trading or, if the Security is not listed or admitted to trading on
        any national securities exchange, 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 Security is not quoted by any such
        organization, the average of the closing bid and asked prices as
        furnished by a professional market maker making a market in the Security
        selected by the General Partner of the Partnership. The term "Trading
                                                                      -------
        Day" shall mean a day on which the principal national securities
        ---
        exchange on

 
                                                                              27


        which the Security is listed or admitted to trading is open for the
        transaction of business or, if the Security is not listed or admitted to
        trading on any national securities exchange, a Business Day. If on any
        such date no such market maker is making a market in such Security, the
        fair value of such Security on such date as determined in good faith by
        the General Partner of the Partnership shall be used, such determination
        to be described in a statement filed with the Rights Agent.

               (e) No adjustment in the Purchase Price shall be required unless
        such adjustment would require an increase or decrease of at least 1% in
        the Purchase Price; provided, however, that any adjustments which by
                            --------  -------
        reason of this Section 11(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.
        Notwithstanding the first sentence of this Section 11(e), any adjustment
        required by this Section 11 shall be made no later than the earlier of
        (i) three years from the date of the transaction which requires such
        adjustment or (ii) the date of the expiration of the right to exercise
        any Rights.

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

 
                                                                              28

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

                      (h) Unless the Partnership shall have exercised its
        election as provided in Section 11(i), upon each adjustment of the
        Purchase Price as a result of the calculations made in Sections 11(b)
        and (c), each Right outstanding immediately prior to the making of such
        adjustment shall thereafter evidence the right to purchase, at the
        adjusted Purchase Price, that number of Units (calculated to the nearest
        Unit) obtained by (i) multiplying (x) the number of Units covered by a
        Right immediately prior to such 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 Partnership may elect on or after the date of any
        adjustment of the Purchase Price to adjust the number of Rights, in
        substitution for any adjustment in the number of Units purchasable upon
        the exercise of a Right. Each of the Rights outstanding after such
        adjustment of the number of Rights shall be exercisable for the number
        of Units for which a Right was exercisable immediately prior to such
        adjustment. Each Right held of record prior to such adjustment of the
        number of Rights shall become that number of Rights (calculated to the
        nearest whole Right) 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
        Partnership shall make a public announcement of its election to adjust
        the number of 

 
                                                                              29

        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 Right Certificates have been issued, shall be at
        least 10 days later than the date of the public announcement. If Right
        Certificates have been issued, upon each adjustment of the number of
        Rights pursuant to this Section 11(i), the Partnership may, as promptly
        as practicable, cause to be distributed to holders of record of Right
        Certificates on such record date Right Certificates evidencing, subject
        to Section 14 hereof, the additional Rights to which such holders shall
        be entitled as a result of such adjustment, or, at the option of the
        Partnership, shall cause to be distributed to such holders of record in
        substitution and replacement for the Right Certificates held by such
        holders prior to the date of adjustment, and upon surrender thereof, if
        required by the Partnership, new Right Certificates evidencing all the
        Rights to which such holders shall be entitled after such adjustment.
        Right Certificates so to be distributed shall be issued, executed and
        countersigned in the manner provided for herein and shall be registered
        in the names of the holders of record of Right 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 Units issuable upon the exercise of the
        Rights, the Right Certificates theretofore and thereafter issued may
        continue to express the Purchase Price and the number of Units which
        were expressed in the initial Right Certificates issued hereunder.

                      (k) Before taking any action that would cause an
        adjustment reducing the Purchase Price below the then par value, if any,
        of the securities issuable upon exercise of the Rights, the Partnership
        shall take any action which may, in the opinion of its 

 
                                                                              30

        counsel, be necessary in order that the Partnership may validly and
        legally issue fully paid Units or other such securities at such adjusted
        Purchase Price.

                      (l) In any case in which this Section 11 shall require
        that an adjustment in the Purchase Price be made effective as of a
        record date for a specified event, the Partnership may elect to defer
        until the occurrence of such event the issuing to the holder of any
        Right exercised after such record date of the Units and other securities
        of the Partnership, if any, issuable upon such exercise over and above
        the Units and other securities of the Partnership, if any, issuable upon
        such exercise on the basis of the Purchase Price in effect prior to such
        adjustment; provided, however, that the Partnership shall deliver to
                    --------  -------
        such holder a due bill or other appropriate instrument evidencing such
        holder's right to receive such additional interests upon the occurrence
        of the event requiring such adjustment.

                      (m) Anything in this Section 11 to the contrary
        notwithstanding, the Partnership 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 it in
        its sole discretion shall determine to be advisable in order that (i)
        any consolidation or subdivision of the Units, (ii) issuance wholly for
        cash of any Units at less than the current market price, (iii) issuance
        wholly for cash or Units or securities which by their terms are
        convertible into or exchangeable for Units, (iv) distributions on Units
        payable in Units or (v) issuance of rights, options or warrants referred
        to hereinabove in Section 11(b), hereafter made by the Partnership to
        holders of its Units shall not be taxable to such holders.

 
                                                                              31

                      (n) Anything in this Agreement to the contrary
        notwithstanding, in the event that at any time after the date of this
        Agreement and prior to the Distribution Date, the Partnership shall (i)
        make a distribution on the Units payable in Units or (ii) effect a
        subdivision, combination or consolidation of the Units (by
        reclassification or otherwise than by payment of a distribution payable
        in Units) into a greater or lesser number of Units, then in any such
        case, the number of Rights associated with each Unit then outstanding,
        or issued or delivered thereafter, shall be proportionately adjusted so
        that the number of Rights thereafter associated with each Unit following
        any such event shall equal the result obtained by multiplying the number
        of Rights associated with each Unit immediately prior to such event by a
        fraction the numerator of which shall be the total number of Units
        outstanding immediately prior to the occurrence of the event and the
        denominator of which shall be the total number of Units outstanding
        immediately following the occurrence of such event.

                      (o) The Partnership agrees that, after the earlier of the
        Distribution Date or the Unit Acquisition Date, it will not, except as
        permitted by Sections 23, 24 or 27 hereof, take (or permit any
        Subsidiary to take) any action if at the time such action is taken it is
        reasonably foreseeable that such action will diminish substantially or
        eliminate the benefits intended to be afforded by the Rights.

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

 
                                                                              32


in accordance with Section 25 hereof (if so required under Section 25 hereof).
The Rights Agent shall be fully protected in relying on any such certificate and
on any adjustment therein contained, and shall not be obligated or responsible
for calculating any adjustment, and shall not be deemed to have knowledge of any
such adjustment unless and until it shall have received such certificate.



               Section 13. Consolidation, Merger or Sale or Transfer of Assets
                           ---------------------------------------------------
or Earnings Power. (a) Except pursuant to a transaction approved in advance by
- -----------------
the General Partner, in the event, directly or indirectly, at any time after any
Person has become an Acquiring Person, (i) the Partnership shall merge with and
into any other Person, (ii) any Person shall consolidate with the Partnership,
or any Person shall merge with and into the Partnership and the Partnership
shall be the continuing or surviving corporation of such merger and, in
connection with such merger, all or part of the Units shall be changed into or
exchanged for common stock, limited partnership interests or other securities of
any other Person (or of the Partnership) or cash or any other property, or (iii)
the Partnership shall sell or otherwise transfer (or one or more of its
Subsidiaries shall sell or otherwise transfer), in one or more transactions,
assets or earning power aggregating 50% or more of the assets or earning power
of the Partnership and its Subsidiaries (taken as a whole) to any other Person
(other than the Partnership or one or more of its wholly-owned Subsidiaries),
then upon the first occurrence of such event, proper provision shall be made so
that: (A) each holder of record of a Right (other than Rights which have become
void pursuant to Section 11(a)(ii)) shall thereafter have the right to receive,
upon the exercise thereof at a price equal to the then current Purchase Price
multiplied by the number of Units for which a Right was exercisable (whether or
not such Right was then exercisable) immediately prior to the time that any
Person first became an Acquiring Person (each as subsequently adjusted
thereafter pursuant 

 
                                                                              33

to Sections 11(a)(i), 11(b), 11(c), 11(h), 11(i) and 11(m)), in accordance with
the terms of this Agreement, such number of validly issued, fully paid and non-
assessable and freely tradeable shares of common stock, limited partnership
interests or equivalent securities of the Principal Party (as defined herein)
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 Units for which a Right was exercisable
immediately prior to the time that any Person first became an Acquiring Person
(as subsequently adjusted thereafter pursuant to Sections 11(a)(i), 11(b),
11(c), 11(h), 11(i) and 11(m)) and (2) dividing that product by 50% of the then
current market price of the common stock, limited partnership interests or
equivalent securities of such Principal Party (determined pursuant to Section
11(d)(i) hereof) on the date of consummation of such consolidation,
merger, sale or transfer; provided that the Purchase Price and the number of
                          --------
shares of common stock, limited partnership interests or equivalent securities
of such Principal Party issuable upon exercise of each Right shall be further
adjusted as provided in Section 11(f) of this Agreement to reflect any events
occurring in respect of such Principal Party after the date of the such
consolidation, merger, sale or transfer; (B) such Principal Party shall
thereafter be liable for, and shall assume, by virtue of such consolidation,
merger, sale or transfer, all the obligations and duties of the Partnership
pursuant to this Agreement; (C) the term "Partnership" shall thereafter be
deemed to refer to such Principal Party; and (D) such Principal Party shall take
such steps (including, but not limited to, the reservation of a sufficient
number of shares of its common stock, limited partnership interests or
equivalent securities in accordance with Section 9 hereof) in connection with
such 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 securities thereafter deliverable upon 

 
                                                                              34

the exercise of the Rights; provided that, upon the subsequent occurrence of any
consolidation, merger, sale or transfer of assets or other extraordinary
transaction in respect of such Principal Party, each holder of a Right shall
thereupon be entitled to receive, upon exercise of a Right and payment of the
Purchase Price as provided in this Section 13(a), such cash, units, rights,
warrants and other property which such holder would have been entitled to
receive had such holder, at the time of such transaction, owned the common
stock, limited partnership interests or equivalent securities of the Principal
Party receivable upon the exercise of a Right pursuant to this Section 13(a),
and such Principal Party shall take such steps (including, but not limited to,
reservation of common stock, limited partnership interests or equivalent
securities) as may be necessary to permit the subsequent exercise of the Rights
in accordance with the terms hereof for such cash, shares, rights, warrants and
other property.

               (b)    "Principal Party" shall mean
                       ---------------
                      (i) in the case of any transaction described in (i) or
        (ii) of the first sentence of Section 13(a) hereof: (A) the Person that
        is the issuer of the securities into which the Units are converted in
        such merger or consolidation, or, if there is more than one such issuer,
        the issuer the common stock, limited partnership interests or equivalent
        securities of which have the greatest aggregate market value of common
        stock, limited partnership interests or equivalent securities
        outstanding, or (B) if no securities are so issued, (x) the Person that
        is the other party to the merger, if such Person survives said merger,
        or, if there is more than one such Person, the Person the common stock,
        limited partnership interests or equivalent securities of which have the
        greatest aggregate market value of common stock, limited partnership
        interests or equivalent securities outstanding or (y) if the Person that
        is the other party to the merger does not survive the merger, the 

 
                                                                              35

        Person that does survive the merger (including the Partnership if it
        survives) or (z) the Person resulting from the consolidation; and

                      (ii) in the case of any transaction described in (iii) of
        the first sentence in Section 13(a) hereof, the Person that is the party
        receiving the greatest portion of the assets or earning power
        transferred pursuant to such transaction or transactions, or, if each
        Person that is a party to such transaction or transactions receives the
        same portion of the assets or earning power so transferred or if the
        Person receiving the greatest portion of the assets or earning power
        cannot be determined, whichever of such Persons as is the issuer of
        common stock, limited partnership interests or equivalent securities
        having the greatest aggregate market value of common stock, limited
        partnership interests or equivalent securities outstanding;

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

 
                                                                              36

are not owned, directly or indirectly, by the same Person, the rules set forth
in clauses (1) and (2) above shall apply to each of the owners having an
interest in the venture as if the Person owned by the joint venture was a
Subsidiary of both or all of such joint venturers, and the Principal Party in
each such case shall bear the obligations set forth in this Section 13 in the
same ratio as its interest in such Person bears to the total of such interests.

               (c) The Partnership shall not consummate any consolidation,
merger, sale or transfer referred to in Section 13(a) hereof unless prior
thereto the Partnership and the Principal Party involved therein shall have
executed and delivered to the Rights Agent an agreement confirming that the
requirements of Sections 13(a) and (b) hereof shall promptly be performed in
accordance with their terms and that such consolidation, merger, sale or
transfer of assets shall not result in a default by the Principal Party under
this Agreement as the same shall have been assumed by the Principal Party
pursuant to Sections 13(a) and (b) hereof and providing that, as soon as
practicable after executing such agreement pursuant to this Section 13, the
Principal Party will:

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

                      (ii) use its best efforts, if the common stock, limited
        partnership interests or equivalent securities of the Principal Party
        shall be listed or admitted to 

 
                                                                              37

        trading on the New York Stock Exchange or on another national securities
        exchange, to list or admit to trading (or continue the listing of) the
        Rights and the securities purchasable upon exercise of the Rights on the
        New York Stock Exchange or such securities exchange, or, if the common
        stock, limited partnership interests or equivalent securities of the
        Principal Party shall not be listed or admitted to trading on the New
        York Stock Exchange or a national securities exchange, to cause the
        Rights and the securities receivable upon exercise of the Rights to be
        reported by such other system then in use;

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

                      (iv) obtain waivers of any rights of first refusal or
        preemptive rights in respect of the Units of the Principal Party subject
        to purchase upon exercise of outstanding Rights.

               (d) In case the Principal Party has provision in any of its
authorized securities or in its certificate of incorporation or by-laws,
partnership agreement or other instrument governing its corporate or partnership
affairs, which provision would have the effect of (i) causing such Principal
Party to issue (other than to holders of Rights pursuant to this Section 13), in
connection with, or as a consequence of, the consummation of a transaction
referred to in this Section 13, common stock, limited partnership interests or
other securities of such Principal Party at less than the then current market
price per unit thereof (determined pursuant to Section 11(d) hereof) or
securities exercisable for, or convertible into, common stock, limited
partnership interests or other securities of such Principal Party at less than
such then current market price, or (ii) providing for any special payment, tax
or similar provision in connection with the issuance 

 
                                                                              38

of the common stock, limited partnership interests or other securities of such
Principal Party pursuant to the provisions of Section 13, then, in such event,
the Partnership hereby agrees with each holder of Rights that it shall not
consummate any such transaction unless prior thereto the Partnership and such
Principal Party shall have executed and delivered to the Rights Agent a
supplemental agreement providing that the provision in question of such
Principal Party shall have been cancelled, waived or amended, or that the
authorized securities shall be redeemed, so that the applicable provision will
have no effect in connection with, or as a consequence of, the consummation of
the proposed transaction.

               (e) The Partnership covenants and agrees that it shall not, at
any time after a Person first becomes an Acquiring Person, enter into any
transaction of the type contemplated by (i) - (iii) of Section 13(a) hereof if
(x) at the time of or immediately after such consolidation, merger, sale,
transfer or other transaction 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, (y) prior to, simultaneously with or immediately after
such consolidation, merger, sale, transfer of other transaction, the security
holders 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 or Associates or
(z) the form or nature of organization of the Principal Party would preclude or
limit the exercisability of the Rights.

               Section 14. Fractional Rights and Fractional Units. (a) The
                           --------------------------------------
Partnership shall not be required to issue fractions of Rights or to distribute
Right Certificates which evidence fractional Rights (i.e. Right's to acquire
less than one Unit). In lieu of such fractional Rights, there shall be paid to
the registered holders of the Right Certificates with regard to which such

 
                                                                              39

fractional Rights would otherwise be issuable, an amount in cash equal to the
same fraction of the current market value of a whole Right. For the purposes of
this Section 14(a), the current market value of a whole Right shall be the
closing price of the Rights for the Trading Day immediately prior to the date on
which such fractional Rights would have been otherwise issuable. The closing
price for any day shall be the last sale price, regular way, or, in case no such
sale takes place on such day, the average of the closing bid and asked prices,
regular way, in either case as reported in the principal consolidated
transaction reporting system with respect to securities listed or admitted to
trading on the New York Stock Exchange or, if the Rights are not listed or
admitted to trading on the New York Stock Exchange, as reported in the principal
consolidated transaction reporting system with respect to securities listed 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 General Partner of the Partnership. 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 General Partner of
the Partnership shall be used.

                      (b)     The Partnership shall not be required to issue
fractions of Units upon exercise of the Rights or to distribute certificates
which evidence fractional Units. Interests in fractions of Units may, at the
election of the Partnership, be evidenced by depositary receipts, pursuant to an
appropriate agreement between the Partnership and a depositary selected by it;

 
                                                                              40

provided, that such agreement shall provide that the holders of such depositary
- --------
receipts shall have all the rights, privileges and preferences to which they are
entitled as beneficial owners of the Units represented by such depositary
receipts. In lieu of fractional Units or depositary receipts, the Partnership
shall pay to the registered holders of Right Certificates at the time such
Rights are exercised as herein provided an amount in cash equal to the same
fraction of the current market value of one Unit. For the purposes of this
Section 14(b), the current market value of a Unit shall be the closing price of
a Unit (as determined pursuant to Section 11(d)(i) hereof) for the Trading Day
immediately prior to the date of such exercise.

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

               Section 15. Rights of Action. All rights of action
                           ----------------
in respect of this Agreement, excepting the rights of action given to the Rights
Agent under Section 18 hereof, are vested in the respective registered holders
of the Right Certificates (and, prior to the Distribution Date, the registered
holders of the Units); and any registered holder of any Right Certificate (or,
prior to the Distribution Date, of the Units), without the consent of the Rights
Agent or of the holder of any other Right Certificate (or, prior to the
Distribution Date, of the Units), on his own behalf and for his own benefit, may
enforce, and may institute and maintain any suit, action or proceeding against
the Partnership to enforce, or otherwise act in respect of, his right to
exercise the Rights evidenced by such Right Certificate (or, prior to the
Distribution Date, such Units) in the manner provided in such Right 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 

 
                                                                              41

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

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

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

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

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

               Section 17. Right Certificate Holder Not Deemed a Holder of
                           -----------------------------------------------
Units. No holder, as such, of any Right Certificate shall be entitled to vote,
- -----
receive distributions or be deemed for any purpose the holder of the Unit or any
other securities of the Partnership which may at any time be issuable on the
exercise of the Rights represented thereby, nor shall anything contained 

 
                                                                              42

herein or in any Right Certificate be construed to confer upon the holder of any
Right Certificate, as such, any of the rights of a holder of Units the
Partnership or any right to vote or upon any matter submitted to holders of
Units at any meeting thereof, or to give or withhold consent to any partnership
action, or to receive notice of meetings or other actions affecting holders of
Units (except as provided in this Agreement), or to receive distributions or
subscription rights, or otherwise, until the Rights evidenced by such Right
Certificate shall have been exercised in accordance with the provisions hereof.

               Section 18. Concerning the Rights Agent. (a) The Partnership
                           ---------------------------
agrees to pay to the Rights Agent reasonable compensation for all services
rendered by it hereunder and, from time to time, on demand of the Rights Agent,
its reasonable expenses and counsel fees and other disbursements incurred in the
administration and execution of this Agreement and the exercise and performance
of its duties hereunder. The Partnership 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 arising therefrom,
directly or indirectly. The indemnification provided for herein shall survive
the expiration of the Rights, the termination of this Agreement and the
resignation or removal of the Rights Agent. The costs and expenses of enforcing
this right of indemnification shall also be paid by the Partnership.

               (b) The Rights Agent shall conclusively rely upon and be
protected and 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 Right Certificate or Unit or for other 

 
                                                                              43

securities of the Partnership, 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, or otherwise upon the advice of counsel as set
forth in Section 20 hereof.

               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
securities transfer or corporate trust powers of the Rights Agent or any
successor Rights Agent, shall be the successor to the Rights Agent under this
Agreement without the execution or filing of any paper or any further act on the
part of any of the parties hereto; provided, that such corporation would be
                                   --------
eligible for appointment as a successor Rights Agent under the provisions of
Section 21 hereof. In case at the time such successor Rights Agent shall succeed
to the agency created by this Agreement, any of the Right Certificates shall
have been countersigned but not delivered, any such successor Rights Agent may
adopt the countersignature of the predecessor Rights Agent and deliver such
Right Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, any successor Rights Agent may
countersign such Right Certificates either in the name of the predecessor Rights
Agent or in the name of the successor Rights Agent; and in all such cases such
Right Certificates shall have the full force provided in the Right Certificates
and in this Agreement.

               (b) In case at any time the name of the Rights Agent shall be
changed and at such time any of the Right Certificates shall have been
countersigned but not delivered the Rights 

 
                                                                              44

Agent may adopt the countersignature under its prior name and deliver Right
Certificates so countersigned; and in case at that time any of the Right
Certificates shall not have been countersigned, the Rights Agent may countersign
such Right Certificates either in its prior name or in its changed name and in
all such cases such Right Certificates shall have the full force provided in the
Right Certificates and in this 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 Partnership and the holders of Right
Certificates, by their acceptance thereof, shall be bound:

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

               (b) Whenever in the performance of its duties under this
        Agreement the Rights Agent shall deem it necessary or desirable that any
        fact or matter be proved or established by the Partnership 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 any one of the Chairman of the Board of Directors, the
        President, any Vice President, the Chief Financial Officer, the
        Treasurer, the Controller or the Secretary of the General Partner on
        behalf of the Partnership 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.

 
                                                                              45

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

               (d) The Rights Agent shall not be liable for or by reason of any
        of the statements of fact or recitals contained in this Agreement or in
        the Right Certificates (except its countersignature thereof) or be
        required to verify the same, but all such statements and recitals are
        and shall be deemed to have been made by the Partnership 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 Right Certificate (except
        its countersignature thereof); nor shall it be responsible for any
        breach by the Partnership of any covenant or condition contained in this
        Agreement or in any Right Certificate; nor shall it be responsible for
        any change in the exercisability of the Rights (including the Rights
        becoming void pursuant to Section 11(a)(ii) hereof) or any adjustment in
        the terms of the Rights (including the manner, method or amount thereof)
        provided for in Sections 3, 11, 13, 23 and 24, or the ascertaining of
        the existence of facts that would require any such change or adjustment
        (except with respect to the exercise of Rights evidenced by Right
        Certificates after receipt of a certificate furnished pursuant to
        Section 12, describing such change or adjustment); nor shall it by any
        act hereunder be deemed to make any representation or warranty as to the
        authorization or reservation of any Units or other securities to be
        issued pursuant to this Agreement or any Right Certificate or as to
        whether any Units or other securities will, when issued, be validly
        authorized and issued, fully paid and nonassessable.

 
                                                                              46

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

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

 
                                                                              47

        received written instructions in response to such application specifying
        the action to be taken or omitted.

               (h) The Rights Agent and any stockholder, director, officer or
        employee of the Rights Agent may buy, sell or deal in any of the Rights
        or other securities of the Partnership or become pecuniarily interested
        in any transaction in which the Partnership may be interested, or
        contract with or lend money to the Partnership 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 Partnership 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
        Partnership resulting from any such act, default, neglect or misconduct,
        provided reasonable care was exercised in the selection and continued
        employment thereof.

               (j) If, with respect to any Rights Certificate surrendered to the
        Rights Agent for exercise or transfer, the certificate contained in the
        form of assignment or the form of election to purchase set forth on the
        reverse thereof, as the case may be, has not been completed to certify
        the holder is not an Acquiring Person (or an Affiliate or Associate
        thereof), a Rights Agent shall not take any further action with respect
        to such requested exercise or transfer without first consulting with the
        Partnership.

               (k) No provision of this Agreement shall require the Rights Agent
        to expend or risk or commit its own funds in the performance of any of
        its duties hereunder or in the 

 
                                                                              48

        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.

               (l) The Rights Agent shall not be required to take notice or be
        deemed to have notice of any fact, event or determination (including,
        without limitation, any dates or events defined in this Agreement or the
        designation of any Person as an Aquiring Person, Affiliate or Associate)
        under this Agreement unless and until the Rights Agent shall be
        specifically notified in writing by the Partnership of such fact, event
        or determination.

               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 30 days' notice in writing mailed to the Partnership and to the
transfer agent of the Units by registered or certified mail, and, following the
Distribution Date, to the holders of the Right Certificates by first-class mail.
The Partnership may remove the Rights Agent or any successor Rights Agent upon
30 days' notice in writing, mailed to the Rights Agent or successor Rights
Agent, as the case may be, and to the transfer agent of the Units by registered
or certified mail, and, following the Distribution Date, to the holders of the
Right Certificates by first-class mail. If the Rights Agent shall resign or be
removed or shall otherwise become incapable of acting, the Partnership shall
appoint a successor to the Rights Agent. If the Partnership shall fail to make
such appointment within a period of 30 days after giving notice of such removal
or after it has been notified in writing of such resignation or incapacity by
the resigning or incapacitated Rights Agent or by the holder of a Right
Certificate (who shall, with such notice, submit his Right Certificate for
inspection by the Partnership), then the registered holder of any Right
Certificate may apply to any court of competent jurisdiction for the
appointment of a new Rights Agent. 

 
                                                                              49

Any successor Rights Agent, whether appointed by the Partnership or by such a
court, shall be a corporation organized and doing business under the laws of the
United States or any State thereof, which is authorized under such laws to
exercise corporate trust or securities transfer powers and is subject to
supervision or examination by federal or state authority and which has at the
time of its appointment as Rights Agent a combined capital and surplus of at
least $50 million. After appointment, the successor Rights Agent shall be vested
with the same powers, rights, duties and responsibilities as if it had been
originally named as Rights Agent without further act or deed; but the
predecessor Rights Agent shall deliver and transfer to the successor Rights
Agent any property at the time held by it hereunder, and execute and deliver any
further assurance, conveyance, act or deed necessary for the purpose. Not later
than the effective date of any such appointment the Partnership shall file
notice thereof in writing with the predecessor Rights Agent and each transfer
agent of the Units, and, following the Distribution Date, mail a notice thereof
in writing to the registered holders of the Right 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 Right Certificates. Notwithstanding
                           ----------------------------------
any of the provisions of this Agreement or of the Rights to the contrary, the
Partnership may, at its option, issue new Right Certificates evidencing Rights
in such forms as may be approved by the General Partner on behalf of the
Partnership to reflect any adjustment or change in the Purchase Price and the
number or kind or class of limited partnership interests or other securities or
property purchasable under the Right Certificates made in accordance with the
provisions of this Agreement. In addition, in connection with the issuance or
sale of Units following the 

 
                                                                              50

Distribution Date and prior to the earlier of the Redemption Date and the Final
Expiration Date, the Partnership may with respect to Units so issued or sold
pursuant to (i) any employee plan or arrangement, (ii) the exercise, conversion
or exchange of securities, notes or debentures issued by the Partnership or
(iii) a contractual obligation of the Partnership in each case existing prior to
the Distribution Date, issue Rights Certificates representing the appropriate
number of Rights in connection with such issuance or sale.

               Section 23. Redemption. (a) The General Partner of the
                           ----------
Partnership may, at any time prior to such time as any Person first becomes an
Acquiring Person, redeem all but not less than all the then outstanding Rights
at a redemption price of $.01 per Right, appropriately adjusted to reflect any
split, Unit distribution or similar transaction occurring after the date hereof
(the redemption price being hereinafter referred to as the "Redemption Price").
                                                            ----------------
The redemption of the Rights may be made effective at such time, on such basis
and with such conditions as the General Partner in its sole discretion may
establish.

               (b) Immediately upon the action of the General Partner ordering
the redemption of the Rights pursuant to paragraph (a) of this Section 23 (or at
such later time as the General Partner may establish for the effectiveness of
such redemption), and without any further action and without any notice, the
right to exercise the Rights will terminate and the only right thereafter of the
holders of Rights shall be to receive the Redemption Price. The Partnership
shall promptly give public notice of any such redemption; provided, however,
                                                          --------  -------
that the failure to give, or any defect in, any such notice shall not affect the
validity of such redemption. Within 10 days after such action of the General
Partner ordering the redemption of the Rights (or such later time as the General
Partner may establish for the effectiveness of such redemption), the Partnership
shall mail a notice of redemption to all the holders of the then outstanding
Rights at 

 
                                                                              51

their last addresses as they appear upon the registry books of the Rights Agent
or, prior to the Distribution Date, on the registry books of the transfer agent
for the Units. 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 shall state the method by which the payment of the Redemption Price
will be made.

               Section 24. Exchange. (a) The General Partner on behalf of the
                            --------
Partnership may, at its option, at any time after any Person first becomes an
Acquiring Person, exchange all or part of the then outstanding and
exercisable Rights (which shall not include Rights that have become void
pursuant to the provisions of Section 11(a)(ii) hereof) for Units at an exchange
ratio of one Unit per Right, (such exchange ratio being hereinafter referred to
as the "Exchange Ratio"). Notwithstanding the foregoing, the General Partner on
        --------------
behalf of the Partnership shall not be empowered to effect such exchange at any
time after (1) any Person (other than an Exempt Person), together with all
Affiliates and Associates of such Person, becomes the Beneficial Owner of Units
aggregating 50% or more of the Units then outstanding or (2) the occurrence of
an event specified in Section 13(a) hereof.

               (b) Immediately upon the action of the General Partner on behalf
of the Partnership ordering the exchange of any Rights pursuant to paragraph (a)
of this Section 24 and without any further action and without any notice, the
right to exercise such Rights shall terminate and the only right thereafter of a
holder of such Rights shall be to receive that number of Units equal to the
number of such Rights held by such holder multiplied by the Exchange Ratio. The
Partnership shall promptly give public notice of any such exchange; provided,
                                                                    --------
however, that the failure to give, or any defect in, such notice shall not
- -------
affect the validity of such exchange. The Partnership shall promptly mail a
notice of any such exchange to all of the 

 
                                                                              52

holders of the Rights so exchanged at their last addresses as they appear upon
the registry books of the Rights Agent. Any notice which is mailed in the manner
herein provided shall be deemed given, whether or not the holder receives the
notice. Each such notice of exchange will state the method by which the exchange
of the Units for Rights will be effected and, in the event of any partial
exchange, the number of Rights which will be exchanged. Any partial exchange
shall be effected pro rata based on the number of Rights (other than Rights
which have become void pursuant to the provisions of Section 11(a)(ii) hereof)
held by each holder of Rights.

               (c) The Partnership shall not, in connection with any exchange
pursuant to this Section 24, be required to issue fractions of Units or to
distribute certificates which evidence fractional Units. In lieu of such
fractional Units, the Partnership shall pay to the registered holders of the
Right Certificates with regard to which such fractional Units would otherwise be
issuable an amount in cash equal to the same fraction of the current market
value of a whole Unit. For the purposes of this paragraph (c), the current
market value of a whole Unit shall be the closing price of a Unit (as determined
pursuant to the second sentence of Section 11(d)(i) hereof) for the Trading Day
immediately prior to the date of exchange pursuant to this Section 24.

               Section 25. Notice of Certain Events. (a) In case the Partnership
                           ------------------------
shall at any time after the earlier of the Distribution Date or the Unit
Acquisition Date propose (i) to declare or pay any distribution on the Units
payable in Units or limited partnership interests of any other class to the
holders of its Unit or to make any other distribution to the holders of its
Units (other than regular periodic cash distributions), (ii) to offer to the
holders of its Unit rights or warrants to subscribe for or to purchase any
additional Units or limited partnership interests of any other class or any
other securities, rights or options, (iii) to effect any reclassification or
recapitalization 

 
                                                                              53

of its Units or to effect a subdivision, combination or consolidation of the
Units, or (iv) to effect the liquidation, dissolution or winding up of the
Partnership, then, in each such case, the Partnership shall give to each holder
of a Right Certificate, in accordance with Section 26 hereof, a notice of such
proposed action, which shall specify the record date for the purposes of such
unit distribution or distribution of rights or warrants, or the date on which
such liquidation, dissolution or winding up is to take place and the date of
participation therein by the holders of the Units, 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 10 days prior to the record date for
determining holders of the Units for purposes of such action, and in the case of
any such other action, at least 10 days prior to the date of the taking of such
proposed action or the date of participation therein by the holders of the
Units, whichever shall be the earlier.

               (b) In case any event described in Section 11(a)(ii) or Section
13 shall occur then the Partnership shall as soon as practicable thereafter give
to each holder of a Right Certificate (or if occurring prior to the Distribution
Date, the holders of the Units) in accordance with Section 26 hereof, a notice
of the occurrence of such event, which notice shall describe such event and the
consequences of such event to holders of Rights under Section 11(a)(ii) and
Section 13 hereof.

penultimate sentence of this Section 27, for so long as the Rights are then
redeemable, the Partnership may in its sole and absolute discretion, and the
Rights Agent shall if the Partnership so directs, supplement or amend any
provision of this Agreement in any respect without the approval of any holders
of the Rights. At any time when the Rights are no longer redeemable, except as

of Rights as such (other than an Acquiring Person or an Affiliate or Associate
of an Acquiring Person), and no such amendment may cause the rights again to
become redeemable or cause the Agreement again to become amendable other than in
accordance with this sentence. Notwithstanding anything contained in this
Agreement to the contrary, no supplement or amendment shall be made which
changes the Redemption Price. Upon the delivery of a certificate from an
appropriate officer of the General Partner on behalf of the Partnership which
states that the proposed supplement or amendment is in compliance with the terms
of this Section 27, the Rights Agent shall execute such supplement or amendment.

               Section 28. Successors. All the covenants and provisions of this
                           ----------

under this Agreement; but this Agreement shall be for the sole and exclusive
benefit of the Partnership, the Rights Agent and the registered holders of the
Right Certificates (and, prior to the Distribution Date, the Units).

               Section 34. 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.

           ----------------
Partnership, a Delaware limited partnership (the "Partnership"), and Harris

 --------------
with the Form of Election to Purchase duly executed. The number of Rights
evidenced by this Rights Certificate (and the number of Units which may be
purchased upon exercise hereof) set forth above, and the Purchase Price set
forth above, are the number and Purchase Price as of April 8 1997, based on the
Units as constituted at such date. As provided in the Rights Agreement, the
Purchase Price, the number of (or other securities or property) which may be
purchased upon the exercise of the Rights and the number of Rights evidenced by
this Right Certificate are subject to modification and adjustment upon the
happening of certain events.

               This Right Certificate is subject to all of the terms, provisions
and conditions of the Rights Agreement, which terms, provisions and conditions
are hereby incorporated herein by reference and made a part hereof and to which
Rights Agreement reference is hereby made for a full description of the rights,

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

               Subject to the provisions of the Rights Agreement, the Rights

or Rights evidenced hereby (other than fractions which may, at the election of
the Partnership, be evidenced by depositary receipts), but in lieu thereof a
cash payment will be made, as provided in the Rights Agreement.

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

purpose until it shall have been countersigned by the Rights Agent.

accordance with the laws of the State of Delware without regard to principles 
of conflict of laws.

        PERSON (AS DEFINED IN THE RIGHTS AGREEMENT) AND CERTAIN TRANSFEREES
        THEREOF WILL BECOME NULL AND VOID AND WILL NO LONGER BE TRANSFERABLE.

                       SUMMARY OF RIGHTS TO PURCHASE UNITS

               On April 8, 1997, BCP Management, Inc., the general partner (the
"General Partner") of Borden Chemicals and Plastics Limited Partnership (the
 ---------------
"Partnership") declared a distribution, to be made on April 21, 1997 (the
 -----------
"Record Date"), of (i) one common unit purchase right (a "Right") for each
 -----------                                              -----
outstanding common unit (a "Unit"; collectively, the "Units") of the Partnership
                            ----                      -----
and (ii) such number of Rights as most closely approximates 1/99th of the number
of Units outstanding on the Record Date (in respect of the General Partner's
interest in the Partnership). The distribution is payable to the record holders
of Units on the Record Date and to the General Partner. Each Right entitles the
holder to purchase from the Partnership one Unit at a price of $21.00 (the
"Purchase Price"), subject to adjustment. The description and terms of the
 --------------
Rights are set forth in a Rights Agreement dated as of April 8, 1997 (the
"Rights Agreement") between the Partnership and Harris Trust and Savings Bank,
 ----------------
as Rights Agent (the "Rights Agent").
                      ------------
                  
               Until the earlier to occur of (i) 10 days following a public
announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") have acquired beneficial ownership of 15% or more of the
 ----------------
outstanding Units or (ii) 10 business days (or such later date as may be
determined by action of the General Partner prior to such time as any person or
group of affiliated persons becomes an Acquiring Person) following the
commencement of, or announcement of an intention to make, a tender offer or
exchange offer the consummation of which would result in the beneficial
ownership by a person or group of 15% or more of the outstanding Units (the
earlier of such dates being called the "Distribution Date"), the Rights (other
                                        -----------------
than those held by the General Partner) will be evidenced, with respect to any
of the certificates for Units outstanding as of the Record Date, by such
certificates for Units together with a copy of this Summary of Rights.

               The Rights Agreement provides that, until the Distribution Date
(or earlier redemption or expiration of the Rights), the Rights will be
transferred with and only with the Units (or in the case of the General Partner,
with the transfer of the general partnership interest). A Right will be issued
with each Unit issued after the date of the initial issuance of the Rights and,
subject to certain exceptions, prior to the Distribution Date. Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
certificates for Units issued after the Record Date upon transfer or new
issuances of Units will contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for Units
outstanding as of the Record Date, even without such notation or a copy of this
Summary of Rights, will also constitute the transfer of the Rights associated
with the Units represented by such certificate. As soon as practicable 


                                      B-1

 
following the Distribution Date, separate certificates evidencing the Rights
("Right Certificates") will be mailed to holders of record of the Units as of
  ------------------
the close of business on the Distribution Date and such separate Right
Certificates alone will evidence the Rights.

               The Rights are not exercisable until the Distribution Date. The
Rights will expire on the earliest to occur of (i) the effective date of the
Merger described in the Agreement and Plan of Conversion, dated as of April 8,
1997, among the Partnership, the General Partner, Borden Chemicals and Plastics
Operating Limited Partnership, BCP Chemicals and Plastics Inc., BCP Chemicals
and Plastics GP Inc. and BCP Chemicals and Plastics L.P. and (ii) April 8, 2007
(the "Final Expiration Date"), unless the Final Expiration Date is extended or
      ---------------------
unless the Rights are earlier redeemed or exchanged by the Partnership, in each
case as described below.

               The Purchase Price payable, and the number of Units or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a
distribution in the form of Units, or a subdivision, combination or
reclassification of the Units, (ii) upon the grant to holders of the Units of
certain rights or warrants to subscribe for or purchase Units at a price, or
securities convertible into Units with a conversion price, less than the
then-current market price of the Units or (iii) upon the distribution to holders
of the Units of evidences of indebtedness or assets (excluding regular periodic
cash distributions or distributions payable in Units) or of subscription rights
or warrants (other than those referred to above).

               In the event that any person or group of affiliated or associated
persons becomes an Acquiring Person, proper provision shall be made so that each
holder of a Right, other than Rights beneficially owned by the Acquiring Person
(which will thereafter be void), will thereafter have the right to receive upon
exercise of the Right at the then current exercise price of the Right, that
number of Units having a market value of two times such exercise price.

               In the event that, after a person or group has become an
Acquiring Person, the Partnership is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold, proper provision will be made so that each holder of a Right
(other than Rights beneficially owned by an Acquiring Person which will have
become void) will thereafter have the right to receive, upon the exercise
thereof of the Right at the then current exercise price of the Right, that
number of shares of common stock, limited partnership interests or equivalent
ownership interests of the person with whom the Partnership has engaged in the
foregoing transaction which number of shares, limited partnership interests or
equivalent ownership interests at the time of such transaction will have a
market value of two times the exercise price of the Right.

               At any time after any person or group becomes an Acquiring Person
and prior to the acquisition by such person or group of 50% or more of the
outstanding Units or the occurrence of an event described in the preceding
paragraph, the General Partner on behalf of the Partnership may exchange the
Rights (other than Rights owned by such person or group which will have become
void), in whole or in part, at an exchange ratio of one Unit per Right (subject
to adjustment).

                                      B-2

 
               With certain exceptions, no adjustment in the Purchase Price will
be required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Units will be issued (other than fractions,
which may, at the election of the Partnership, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Units on the last trading day prior to the date of exercise.

               At any time prior to the time an Acquiring Person becomes such,
the General Partner on behalf of the Partnership may redeem the Rights in whole,
but not in part, at a price of $.01 per Right (the "Redemption Price"). The
                                                    ----------------
redemption of the Rights may be made effective at such time, on such basis and
with such conditions as the General Partner on behalf of the Partnership in its
sole discretion may establish. Immediately upon any redemption of the Rights,
the right to exercise the Rights will terminate and the only right of the
holders of Rights will be to receive the Redemption Price.

               For so long as Rights are then redeemable, the Partnership may,
except with respect to the redemption price, amend the Rights in any manner.
After the Rights are no longer redeemable the Partnership may, except with
respect to the Redemption Price, amend the Rights in any manner that does not
adversely affect the interests of holders of the Rights.

               Until a Right is exercised, the holder thereof, as such, will
have no rights as a holder of Units the Partnership, including, without
limitation, the right to vote or to receive distributions.

               A copy of the Rights Agreement has been filed with the Securities
and Exchange Commission as an Exhibit to a Registration Statement on Form 8-A. A
copy of the Rights Agreement is available free of charge from the Partnership.
This summary description of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement, as the same may
be amended from time to time, which is hereby incorporated herein by reference.
