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

          Agreement, dated as of April 8, 1997, between Borden Chemicals and

 -----------                                                          
corporation (the "Rights Agent").
                  ------------   
          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 "Exchange Act"),

     as in effect on the date of this Agreement.
          (c) "Agreement and Plan of Conversion" shall mean the Agreement and

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

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.
Notwithstanding 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 exercise 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

 
                                                                              10

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.

          (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

 
                                                                              11

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.

          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

 
                                                                              12

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 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,

 
                                                                              13

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 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

 
                                                                              14

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 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

 
                                                                              15

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 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

 
                                                                              16

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.  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

 
                                                                              17

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 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.

          (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

 
                                                                              18

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 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.

 
                                                                              19

          (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 or (D) issue any
          limited partnership interests in the Partnership in a 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

 
                                                                              20

          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 Purchase Price
                                    --------  -------                         
          and the number of Units so receivable upon 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

 
                                                                              21

          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 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

 
                                                                              22

          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 (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

 
                                                                              23

          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 "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

 
                                                                              24

          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 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

 
                                                                              25

     shall not be deemed outstanding for the purpose of any such computation.
     Such adjustment shall be made successively whenever such a record date is
     fixed; and in the event that such rights, options or warrants are not so
     issued, the Purchase Price shall be adjusted to be the Purchase Price which
     would then be in effect if such record date had not been fixed.

          (c) In case the 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.

 
                                                                              26

          (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 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

 
                                                                              27

     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 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

 
                                                                              28

     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.

          (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.

 
                                                                              29

     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 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

 
                                                                              30

     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 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

 
                                                                              31

     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.

          (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.

 
                                                                              32

          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 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

 
                                                                              33

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 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;

 
                                                                              34

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 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

 
                                                                              35

     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 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

 
                                                                              36

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 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

 
                                                                              37

     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 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

 
                                                                              38

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 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

 
                                                                              39

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
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

 
                                                                              40

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; 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

 
                                                                              41

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 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

 
                                                                              42

     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 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 of 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

 
                                                                              43

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 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

 
                                                                              44

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 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

 
                                                                              45

     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.

          (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

 
                                                                              46

     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.

          (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

 
                                                                              47

     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 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

 
                                                                              48

     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 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 Acquiring 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

 
                                                                              49

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.
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,

 
                                                                              50

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
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

 
                                                                              51

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 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

 
                                                                              52

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
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

 
                                                                              53

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 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

restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated.

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 out standing 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).

          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,

                                      B-2

 
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 of 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.
