                                JANUARY   , 1998
    
 
                            ------------------------
 
Dear Common Unit holders of Kinder Morgan Energy Partners, L.P. ("KMEP")
  and Santa Fe Pacific Pipeline Partners, L.P. ("Santa Fe"):
 
   
    Attached is a Notice of Special Meeting of Common Unit Holders for each of
KMEP and Santa Fe and an accompanying Joint Proxy Statement/Prospectus which
describes the matters to be acted upon at the Special Meetings. At the Special
Meetings, holders of the Common Units of KMEP ("KMEP Common Units") and holders
of the Common Units of Santa Fe ("Santa Fe Common Units") will be asked to
consider and vote upon certain proposals related to KMEP's acquisition of
substantially all of the assets of Santa Fe and the subsequent dissolution and
liquidation of Santa Fe pursuant to a Purchase Agreement (the "Purchase
Agreement") dated as of October 18, 1997 between KMEP, Kinder Morgan G.P., Inc.,
the general partner of KMEP (the "KM General Partner"), Santa Fe, Santa Fe
Pacific Pipelines, Inc., the general partner of Santa Fe (the "SF General
Partner"), and SFP Pipeline Holdings, Inc., the parent company of the SF General
Partner ("SF Holdings"). Under the Purchase Agreement, an affiliate of KMEP will
acquire the general partner interest in Santa Fe from the SF General Partner for
$84.4 million in cash. The SF General Partner's approximate 1% general partner
interest in Santa Fe's operating partnership will be converted into a special
limited partner (non-voting) interest and approximately one-half of such
interest will be redeemed by Santa Fe's operating partnership for $5.8 million
in cash. The transactions contemplated by the Purchase Agreement are referred to
herein as the "Transaction." Upon completion of the Transaction, each former
Santa Fe Common Unit will represent the right to receive 1.39 KMEP Common Units
(which will result in the issuance to the public holders of Santa Fe Common
Units of an aggregate of approximately 15.3 million KMEP Common Units and the
issuance to the SF General Partner of an aggregate of approximately 11.3 million
KMEP Common Units). In order to complete the Transaction, the partnership
agreements of Santa Fe and its operating partnership must be amended as
described in the accompanying Joint Proxy Statement/Prospectus. As a result of
the Transaction, the holders of the approximately $218 million Variable Rate
Exchangeable Debentures Due 2010 ("VREDs") issued by SF Holdings will have the
right to exchange the VREDs for the KMEP Common Units to be received by the SF
General Partner.
    
 
   
    Holders of KMEP Common Units and Santa Fe Common Units are urged to review
carefully the attached Joint Proxy Statement/Prospectus, which contains a
detailed description of the Transaction and related matters. Answers to some
commonly asked questions are found on pages (v) through (ix) of the Joint Proxy
Statement/Prospectus.
    
 
   
    The proposed Transaction is subject to, among other conditions, the approval
of the matters described in the Joint Proxy Statement/Prospectus by the holders
of a majority of the outstanding KMEP Common Units and 66 2/3% of the
outstanding Santa Fe Common Units (other than Santa Fe Common Units held by the
SF General Partner and its affiliates).
    
 
   
    FOR THE REASONS DETAILED IN THE JOINT PROXY STATEMENT/PROSPECTUS, THE BOARD
OF DIRECTORS OF THE KM GENERAL PARTNER AND THE BOARD OF DIRECTORS OF THE SF
GENERAL PARTNER HAVE EACH UNANIMOUSLY DETERMINED THAT THE PURCHASE AGREEMENT AND
THE TRANSACTION ARE IN THE BEST INTERESTS OF KMEP AND SANTA FE, RESPECTIVELY,
AND THEIR RESPECTIVE COMMON UNIT HOLDERS. THE BOARD OF DIRECTORS OF THE KM
GENERAL PARTNER HAS UNANIMOUSLY APPROVED THE PURCHASE AGREEMENT AND THE
TRANSACTION AND RECOMMENDS THAT HOLDERS OF KMEP COMMON UNITS VOTE FOR APPROVAL
OF THE PROPOSALS TO BE CONSIDERED AT THE KMEP SPECIAL MEETING AS DESCRIBED IN
THE ATTACHED JOINT PROXY STATEMENT/PROSPECTUS. THE BOARD OF DIRECTORS OF THE SF
GENERAL PARTNER HAS UNANIMOUSLY APPROVED THE TRANSACTION AND RECOMMEND THAT
HOLDERS OF SANTA FE COMMON UNITS VOTE FOR APPROVAL OF THE TRANSACTION AT THE
SANTA FE SPECIAL MEETING AS DESCRIBED IN THE ATTACHED JOINT PROXY
STATEMENT/PROSPECTUS.
    
 
   
    Holders of KMEP Common Units and Santa Fe Common Units are strongly urged to
review carefully the attached Joint Proxy Statement/Prospectus, which contains a
detailed description of, among other things, the Transaction and Risk Factors
associated therewith.
    
 
    Because an abstention or broker non-vote or the failure to return a proxy
will have the same effect as a vote cast AGAINST the proposals, your
participation at the Special Meetings, in person or by proxy, is especially
important. Even if you plan to attend the Special Meeting, we hope you will
sign, date and return your proxy promptly in the enclosed envelope that has been
provided for your convenience. This will not limit your right to vote in person
or to attend the Special Meeting. You may revoke your proxy by following the
procedures set forth in the accompanying Joint Proxy Statement/Prospectus.

    NOTICE IS HEREBY GIVEN that a special meeting of holders of Common Units
("KMEP Common Units") of Kinder Morgan Energy Partners, L.P., a Delaware limited
partnership ("KMEP"), will be held on February 24, 1998 commencing at 10:30
a.m., local time, at Bracewell & Patterson, L.L.P., South Tower Pennzoil Place,
711 Louisiana Street, Suite 2600, Houston TX 77002 to consider and act upon the
following matters:
    
 
   
          1. To consider and vote upon a proposal to approve KMEP's issuance of
    KMEP Common Units pursuant to a Purchase Agreement dated as of October 18,
    1997 (the "Purchase Agreement"), among KMEP, Kinder Morgan G.P., Inc., the

    general partner of Santa Fe (the "SF General Partner"), and SFP Pipeline
    Holdings, Inc., the parent company of the SF General Partner.
    
 
          2. To consider and act upon such other business as may be properly
    brought before the special meeting or any adjournment or postponement
    thereof.
 
    THE BOARD OF DIRECTORS OF THE KM GENERAL PARTNER UNANIMOUSLY RECOMMENDS THAT
KMEP COMMON UNIT HOLDERS VOTE IN FAVOR OF THE ISSUANCE OF KMEP COMMON UNITS
PURSUANT TO THE PURCHASE AGREEMENT.
 
   
    A form of Proxy and a Joint Proxy Statement/Prospectus containing more
detailed information with respect to the matters to be considered at the special
meeting (including the Purchase Agreement included as Annex A in the
accompanying Annex Volume) accompany and form a part of this notice. All
questions should be directed to Georgeson & Company, Inc. as the Information
Agent and Proxy Solicitor at 1-800-223-2064.
    
 
   
    The close of business on January 11, 1998 has been fixed as the record date
for the determination of holders of KMEP Common Units entitled to notice of, and
to vote at, the special meeting and any adjournment or postponement thereof, and
only KMEP Common Unit holders of record at such time will be entitled to notice

entitled to rights of appraisal or similar rights of dissenters under the
Delaware Revised Uniform Limited Partnership Act or under the Second Amended and
Restated Agreement of Limited Partnership of KMEP in connection with the
Purchase Agreement and the transactions contemplated thereby.
    
 
    The proposal regarding issuance of KMEP Common Units pursuant to the
Purchase Agreement requires the affirmative vote of the holders of a majority of
the outstanding KMEP Common Units. As a result, an abstention or broker non-vote
or the failure to return a proxy will have the same effect as a vote against
such proposal.
 
    When the proxies are returned properly executed, the KMEP Common Units
represented thereby will be voted in accordance with the indicated instructions.
However, if no instructions have been specified on the properly executed and
returned proxy, the KMEP Common Units represented thereby will be voted FOR the
approval of the issuance of KMEP Common Units pursuant to the Purchase
Agreement. Any holder of a KMEP Common Unit giving a proxy has the right to
revoke it at any time before it is voted by filing with the Secretary of the KM

bearing a later date. Proxies also may be revoked by attending the meeting and
voting in person.

    A SPECIAL COMMITTEE OF THE BOARD OF DIRECTORS OF THE SF GENERAL PARTNER,

GENERAL PARTNER, HAS CONSIDERED THE BENEFITS OF THE TRANSACTION AS WELL AS THE
RISKS ASSOCIATED THEREWITH, AND HAS UNANIMOUSLY APPROVED THE TRANSACTION AS

SANTA FE COMMON UNITS ARE URGED TO REVIEW CAREFULLY THE BACKGROUND AND REASONS
FOR THE TRANSACTION AND THE RISK FACTORS ASSOCIATED WITH THE TRANSACTION
DESCRIBED IN THE ATTACHED JOINT PROXY STATEMENT/PROSPECTUS.
    
 
   
    A form of Proxy and a Joint Proxy Statement/Prospectus containing more

                 KINDER MORGAN ENERGY PARTNERS, L.P. PROSPECTUS
 
   
    This Joint Proxy Statement/Prospectus is being furnished to holders of
Common Units (the "KMEP Common Units") representing limited partner interests in
Kinder Morgan Energy Partners, L.P., a Delaware limited partnership ("KMEP"), in
connection with the solicitation of proxies by the Board of Directors of Kinder
Morgan, G.P., Inc., the general partner of KMEP (the "KM General Partner"), for
use at the special meeting of holders of KMEP Common Units (the "KMEP Special
Meeting") to be held on February 24, 1998, commencing at 10:30 a.m. local time,
at Bracewell & Patterson, L.L.P., located at South Tower Pennzoil Place, 711
Louisiana Street, Suite 2600, Houston TX 77002 and at any adjournment or
postponement thereof.
    
 
   
    This Joint Proxy Statement/Prospectus is also being furnished to holders of
Common Units (the "Santa Fe Common Units") representing limited partner
interests in Santa Fe Pacific Pipeline Partners, L.P., a Delaware limited
partnership ("Santa Fe"), in connection with the solicitation of proxies by the
Board of Directors of Santa Fe Pacific Pipelines, Inc., the general partner of
Santa Fe (the "SF General Partner"), for use at the special meeting of holders
of Santa Fe Common Units (the "Santa Fe Special Meeting" and together with the
KMEP Special Meeting, the "Special Meetings") to be held on February 24, 1998,
commencing at 9:00 a.m., local time, at the Doubletree Hotel, located at 100 The
City Drive, Orange, California 92868 and at any adjournment or postponement
thereof.
    
 
   
    The Purchase Agreement (the "Purchase Agreement") dated as of October 18,
1997 between KMEP, the KM General Partner, Santa Fe, the SF General Partner and
SFP Pipeline Holdings, Inc., the parent company of the SF General Partner ("SF
Holdings"), provides, among other things, that (i) KMEP will acquire from Santa
Fe substantially all of the limited partner interests in SFPP, L.P., the
operating partnership of Santa Fe (the "SF Operating Partnership"), in exchange
for a number of KMEP Common Units such that upon the liquidation of Santa Fe
each holder of Santa Fe Common Units shall be distributed the right to receive
1.39 KMEP Common Units for each Santa Fe Common Unit (the "Exchange Ratio"),
which will result in the issuance to the public holders of Santa Fe Common Units
of an aggregate of approximately 15.3 million KMEP Common Units and the issuance
to the SF General Partner of an aggregate of approximately 11.3 million KMEP
Common Units, and (ii) an affiliate of KMEP will acquire the general partner
interest in Santa Fe from the SF General Partner in exchange for $84.4 million
in cash. Immediately following such purchases, an affiliate of KMEP will
liquidate Santa Fe and, as a result of such liquidation, (a) each former Santa
Fe Common Unit will represent the right to receive (subject to certain
provisions with respect to fractional KMEP Common Units) 1.39 KMEP Common Units
and (b) a designated affiliate of KMEP (as the successor general partner of
Santa Fe) will receive the remaining limited partner interest in the SF
Operating Partnership and any remaining assets of Santa Fe. The SF General
Partner's general partner interest in the SF Operating Partnership will be
converted into an approximate 1% special limited partner (non-voting) interest
(the "Special LP Interest") and approximately one-half of such interest will be
redeemed by the SF Operating Partnership for $5.8 million in cash (the "Special
Distribution"). In order to complete the transactions contemplated by the
Purchase Agreement, the partnership agreements of Santa Fe and the SF Operating
Partnership will be amended. The transactions contemplated by the Purchase
Agreement are referred to herein as the "Transaction." As a result of the
Transaction, the holders of the approximate $218 million principal amount of
Variable Rate Exchangeable Debentures Due 2010 ("VREDs") issued by SF Holdings
will have the right to exchange the VREDs for the KMEP Common Units to be
received by the SF General Partner.
    
 
    Holders of Santa Fe Common Units and KMEP Common Units do not have rights of
appraisal or similar rights of dissenters in connection with the Transaction.
 
    This Joint Proxy Statement/Prospectus also constitutes a prospectus of KMEP
with respect to KMEP Common Units to be issued to holders of Santa Fe Common
Units upon the liquidation of Santa Fe following the closing of the Transaction.
 
   
    The New York Stock Exchange ("NYSE") has approved for listing on the NYSE
the KMEP Common Units to be issued in connection with the Transaction, subject
to Unit holders' approval of the matters to be voted on at the Special Meetings
and official notice of issuance.

1.  WHAT IS KINDER MORGAN ENERGY PARTNERS, L.P. ?
 
   
    Kinder Morgan Energy Partners, L.P. is a publicly traded Delaware limited
partnership created in August 1992 to acquire and operate the natural gas
liquids pipelines of Enron Corp. In this Joint Proxy Statement/Prospectus, we
have referred to Kinder Morgan Energy Partners, L.P. as "KMEP." The sole general
partner of KMEP is Kinder Morgan, G.P., Inc., a Delaware corporation. In this
Joint Proxy Statement/Prospectus, we have referred to Kinder Morgan, G.P., Inc.
as the "KM General Partner." KMEP manages a diversified portfolio of midstream
energy assets and it is the sole owner and operator of three pipeline systems,
which transport natural gas liquids, refined petroleum products and carbon
dioxide, and two modern, high-speed coal terminaling facilities. KMEP operates
through three operating partnerships of which the KM General Partner is the
general partner and KMEP is the limited partner. The Second Amended and Restated
Agreement of Limited Partnership of KMEP is described in detail on pages 106
through 121 of the Joint Proxy Statement/Prospectus and which is included as
Annex D in the Annex Volume which accompanies and forms a part of this Joint
Proxy Statement/Prospectus.
    
 
    In February 1997, the current management of KMEP acquired the stock of the
KM General Partner from Enron Corp. The current management's business strategy
is to operate KMEP as a growth-oriented publicly traded limited partnership by
reducing operating costs, better utilizing and expanding its asset base, and
making selective, strategic acquisitions with the goal of increasing KMEP common
unit holder cash distributions.
 
    KMEP's headquarters and executive offices are located at 1301 McKinney
Street, Suite 3450, Houston, Texas 77010 and its telephone number is (713)
844-9500.
 
   
    For further information regarding KMEP, see "The Parties--KMEP" in this
Joint Proxy Statement/ Prospectus.
    
 
2.  WHAT IS SANTA FE PACIFIC PIPELINE PARTNERS, L.P.?
 
   
    Santa Fe Pacific Pipeline Partners, L.P. is a publicly traded Delaware
limited partnership formed in 1988 to acquire and operate, through one operating
partnership, the refined petroleum products business of Santa Fe Pacific
Corporation, a Delaware corporation. In this Joint Proxy Statement/Prospectus,
we have referred to Santa Fe Pacific Pipeline Partners, L.P. as "Santa Fe."
Santa Fe transports refined petroleum products, including gasoline, diesel fuel
and commercial and military jet fuel via pipeline, primarily for major petroleum
companies, independent refiners, the United States military and marketers and
distributors of such products. Santa Fe also operates 13 truck loading terminals
and provides pipeline service to approximately 44 customer-owned terminals,
three commercial airports and 12 military bases.
    
 
   
    The sole general partner of both Santa Fe and its only operating partnership
is Santa Fe Pacific Pipelines, Inc., a Delaware corporation. In this Joint Proxy
Statement/Prospectus, we have referred to Santa Fe Pacific Pipelines, Inc. as
the "SF General Partner." The only operating partnership owned by Santa Fe is
SFPP, L.P. In this Joint Proxy Statement/Prospectus, we have referred to SFPP,
L.P. as the "SF Operating Partnership."
    
 
    Santa Fe's headquarters and executive offices are located at 1100 Town &
Country Road, Orange, California 92868 and its telephone number is (714)
560-4400.

    For further information regarding Santa Fe, see "The Parties--Santa Fe" in
this Joint Proxy Statement/Prospectus.
    
 
3.  WHAT IS KINDER MORGAN OPERATING L.P. "D"?
 
   
    Kinder Morgan Operating L.P. "D" is the name of the limited partnership to
be formed by KMEP, as the sole limited partner, and the KM General Partner, as
the sole general partner, to acquire the general partner interest of the SF
General Partner in Santa Fe. In this Joint Proxy Statement/Prospectus, we have
referred to Kinder Morgan Operating L.P. "D" as "OLP-D."
    
 
   
    For further information regarding OLP-D, see "The
Parties--KMEP--Organizational Structure" in this Joint Proxy
Statement/Prospectus.
    
 
   
4.  HOW WILL KMEP BE COMBINED WITH THE BUSINESS OF SANTA FE?
    
 
   
    In this Joint Proxy Statement/Prospectus, we have referred to the
transactions involved in KMEP's acquisition of substantially all of the assets
of Santa Fe as the "Transaction." Pursuant to the Purchase Agreement, dated
October 18, 1997, among KMEP, the KM General Partner, Santa Fe, the SF General
Partner, and SFP Pipeline Holdings, Inc., a Delaware corporation (the sole owner
of the SF General Partner), KMEP will acquire from Santa Fe substantially all of
the limited partner interests in the SF Operating Partnership in exchange for a
number of common units of KMEP such that upon the liquidation of Santa Fe each
holder of Santa Fe Common Units shall be distributed the right to receive 1.39
common units of KMEP for each common unit of Santa Fe (subject to certain
provisions for fractional units). OLP-D will acquire the general partner
interest in Santa Fe from the SF General Partner in exchange for $84.4 million
in cash and will become the new general partner of Santa Fe. Subsequently, Santa
Fe will be liquidated and each former Santa Fe common unit will represent the
right to receive (subject to certain provisions for fractional units) 1.39
common units of KMEP. Upon liquidation of Santa Fe, OLP-D will receive the
remaining limited partner interest in the SF Operating Partnership and any
remaining assets of Santa Fe. The Purchase Agreement is described in detail on
pages 81 through 88 and a copy of the entire Purchase Agreement is included as
Annex A in the Annex Volume which accompanies and forms a part of this Joint
Proxy Statement/Prospectus.
    
 
5.  HOW DOES OLP-D BECOME THE GENERAL PARTNER OF SF OPERATING PARTNERSHIP?
 
   
    KMEP will contribute all of its limited partner interest in the SF Operating
Partnership to OLP-D. Subsequently, such interest is to be converted into a
general partner interest, giving OLP-D a 99% general partner interest in the SF
Operating Partnership.
    
 
   
6.  WHAT WILL HAPPEN TO THE SF GENERAL PARTNER'S GENERAL PARTNER INTEREST IN THE
    SF OPERATING PARTNERSHIP?
    
 
   
    The SF General Partner's general partner interest in the SF Operating
Partnership will be converted into a special limited partner (non-voting)
interest and approximately one-half of that interest will be redeemed for $5.8
million, giving the SF General Partner a 0.5% special limited partner
(non-voting) interest. As a result, OLP-D's general partner interest will
increase from 99% to 99.5%.
    
 
7.  WHY IS KMEP PROPOSING TO COMBINE WITH SANTA FE? HOW WILL KMEP COMMON UNIT
  HOLDERS BENEFIT?
 
    The Board of Directors of the KM General Partner believes that the
Transaction is in the best interests of the holders of the KMEP common units for
the following reasons:
 
    a.  The Transaction is expected to result in an increase in both per common
       unit net income and per common unit declared distributions for KMEP
       common unit holders;
 
                                       vi
<PAGE>
    b.  Significant cost savings are expected to be achieved by combining the
       operations of the two partnerships;
 
    c.  Opportunities to solidify customer relationships and enhance revenue
       growth are expected to be improved as a result of the Transaction;
 
    d.  The Transaction is expected to increase the number of acquisition
       opportunities available to KMEP in the future; and
 
    e.  The financial condition of KMEP is expected to be enhanced as a result
       of the Transaction, thereby facilitating the funding of new growth
       initiatives.
 
   
    To review the background and reasons for the Transaction in greater detail,
see pages 50 through 63 and for a description of Goldman, Sachs & Co.'s opinion
as to the fairness from a financial point of view of the aggregate consideration
to be paid by KMEP pursuant to the Purchase Agreement to KMEP, see pages 64
through 68.
    
 
8.  WHY IS SANTA FE PROPOSING TO COMBINE WITH KMEP? HOW WILL SANTA FE COMMON
  UNIT HOLDERS BENEFIT?
 
   
    The Board of Directors of the SF General Partner believes that the
Transaction is in the best interests of the holders of the Santa Fe common units
for the following reasons:
    
 
    a.  The number of KMEP common units to be received by each holder of Santa
       Fe common units provides the holders of Santa Fe common units with a
       significant premium over the market price of the Santa Fe common units
       prior to the announcement of the Transaction;
 
   
    b.  The Transaction is expected to result in an increased quarterly
       distribution to holders of Santa Fe common units who become holders of
       KMEP common units;
    
 
   
    c.  As holders of KMEP common units, the holders of Santa Fe common units
       will continue to hold an equity security that will entitle them to
       participate in the future of a combined business committed to growth;
    
 
   
    d.  As holders of KMEP common units, the holders of Santa Fe common units
       will hold an investment in a larger and more broadly diversified
       business;
    
 
   
    e.  Significant cost savings are expected to be achieved by combining the
       operations of the two partnerships;
    
 
   
    f.  The management of KMEP has demonstrated an intent to aggressively seek
       appropriate opportunities to grow and to increase the total return to
       holders of KMEP common units; and
    
 
   
    g.  Given the reputation of KMEP and its management for aggressive growth,
       KMEP common units present a potential for trading at higher multiples of
       cash flow than Santa Fe common units, as well as a greater potential for
       appreciation in price.
    
 
   
    A special committee of directors of the SF General Partner, deemed to be
independent of the interests of the SF General Partner, has considered the
benefits presented by the proposed Transaction and weighed them against the
risks associated with the Transaction and has unanimously concluded that the
Transaction is in the best interests of the holders of Santa Fe common units. To
review the background and reasons for the Transaction in greater detail, see
pages 50 through 63. To review the risk factors associated with the Transaction,
see pages 21 through 35. For a description of Smith Barney Inc.'s opinion that
the Exchange Ratio is fair from a financial point of view to the holders of
Santa Fe common units, see pages 68 through 72. For a description of the special
committee's analysis of the Transaction, see pages 50 through 63.

9.  WHEN DO YOU EXPECT TO COMPLETE THE TRANSACTION?
    
 
   
    We are working toward completing the Transaction as quickly as possible. In
addition to the approval of unit holders, we must also satisfy some other
conditions. The special meetings of both the KMEP common unit holders and Santa
Fe common unit holders are scheduled for February 24, 1998, and we intend to
complete the Transaction shortly thereafter.
    
 
10.  WHAT ARE THE TAX CONSEQUENCES TO ME OF THE TRANSACTION?
 
   
    KMEP common unit holders and Santa Fe common unit holders generally will not
have immediate taxable income or gain as a result of the Transaction. For a
description of the material federal income tax consequences of the Transaction
and of holding KMEP common units after the Transaction, see pages 121 through
153.
    
 
11.  WHAT HAPPENS TO MY FUTURE DISTRIBUTIONS?
 
   
    KMEP has announced that it has increased its distributions to $2.25 per KMEP
common unit commencing with the distribution payable with respect to the fourth
quarter of 1997. However, there can be no assurance of KMEP 's ability to
generate sufficient cash flow to continue to pay such distributions. If KMEP
pays a distribution after the closing of the Transaction but prior to the
exchange of Santa Fe common units for KMEP common units, when a holder of Santa
Fe common units properly completes and submits the letter of transmittal along
with such holder's certificates representing common units of Santa Fe, the
holder will be entitled to payment of the distribution along with receipt of the
applicable number of KMEP common units.
    
 
12.  WHAT VOTE OF KMEP COMMON UNIT HOLDERS IS REQUIRED IN ORDER TO APPROVE THE
  TRANSACTION?
 
    At the special meeting of KMEP common unit holders, we must receive votes
from holders of a majority of the KMEP common units that are outstanding "FOR"
the issuance of additional KMEP Common Units pursuant to the Purchase Agreement.
 
13.  WHAT VOTE OF SANTA FE COMMON UNIT HOLDERS IS REQUIRED IN ORDER TO APPROVE
  THE TRANSACTION?
 
   
    At the special meeting of Santa Fe common unit holders, we must receive
votes from holders of at least 66 2/3% of the Santa Fe common units that are
outstanding (other than those owned by the SF General Partner and its
affiliates) "FOR" a single proposal that includes (i) the adoption and approval
of the Purchase Agreement, (ii) the approval of the sale of substantially all of
the assets of Santa Fe, (iii) the approval of the sale by the SF General Partner
of its general partner interest in Santa Fe to OLP-D and the appointment of
OLP-D as the new general partner of Santa Fe, (iv) the approval of the
dissolution of Santa Fe on the closing date of the Transaction, and (v) the
adoption and approval of certain amendments to the limited partnership agreement
of Santa Fe to implement the Transaction. The full text of the proposed
amendments to the Santa Fe limited partnership agreement are included as Annex E
in the Annex Volume which accompanies and forms a part of this Joint Proxy
Statement/Prospectus.
    
 
14.  IF MY UNITS ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER VOTE MY
  UNITS FOR ME?
 
   
    Your broker will vote your units only if you provide instructions on how to
vote. You should instruct your broker how to vote your units upon receipt of
your broker's request for voting instructions. Without instructions, your units
will not be voted. Any units not voted have the effect of a vote against the
proposal. Your action is therefore needed if the Transaction is to be approved.
    
 
15.  SHOULD I SEND IN MY CERTIFICATES REPRESENTING KMEP COMMON UNITS OR SANTA FE
  COMMON UNITS?
 
    No. If you own KMEP common units, your certificates representing KMEP common
units will not be affected by the Transaction. If you own Santa Fe common units,
after the closing of the Transaction you
 
                                      viii
<PAGE>
will receive a letter explaining what to do with your certificates representing
Santa Fe common units to receive the applicable number of KMEP common units.
 
16.  WHEN WILL THE SPECIAL MEETINGS OCCUR?
 
   
    The KMEP special meeting will take place on February 24, 1998, at the
offices of Bracewell & Patterson, L.L.P., 711 Louisiana, Suite 2600, Houston,
Texas 77002 at 10:30 a.m. local time. The Santa Fe special meeting will take
place on February 24, 1998, at the Doubletree Hotel, 100 The City Drive, Orange,
California 92868 at 9:00 a.m. local time. If you are a record holder, you may
attend your partnership's special meeting and vote your units in person, rather
than signing and mailing your proxy card. In addition, you may take back your
proxy at any time prior to the conclusion of the vote at your partnership's
special meeting by following the directions on pages 49 and 50 of this Joint
Proxy Statement/Prospectus and change your vote by either signing and returning
a new proxy or attending your partnership's special meeting and voting in
person.
    
 
17.  WHAT DO I NEED TO DO NOW?
 
   
    Review this Joint Proxy Statement/Prospectus carefully and then indicate on
your proxy card how you want to vote, and sign and mail the proxy card in the
enclosed return envelope as soon as possible, so that your units may be
represented at your partnership's special meeting. If you sign and send in your
proxy and do not indicate how you want to vote, your proxy will be counted as a
vote in favor of the Transaction. If you do not vote or you abstain, it will
have the effect of a vote AGAINST the Transaction.
    
 
   
THE BOARD OF DIRECTORS OF THE GENERAL PARTNER OF KMEP UNANIMOUSLY RECOMMENDS
THAT HOLDERS OF KMEP COMMON UNITS VOTE FOR THE PROPOSED TRANSACTION. THE BOARD
OF DIRECTORS OF THE GENERAL PARTNER OF SANTA FE AND THE SPECIAL COMMITTEE
UNANIMOUSLY RECOMMEND THAT HOLDERS OF SANTA FE COMMON UNITS VOTE FOR THE
PROPOSED TRANSACTION.
    
 
   
UNIT HOLDERS OF KMEP AND SANTA FE ARE URGED TO READ THIS JOINT PROXY
STATEMENT/PROSPECTUS FOR A MORE DETAILED DESCRIPTION OF THE TRANSACTION.

BOTH KMEP COMMON UNITS AND SANTA FE COMMON UNITS ARE URGED TO READ THIS JOINT
PROXY STATEMENT/PROSPECTUS IN ITS ENTIRETY.
 
                                  THE PARTIES
 
KMEP
 
    KMEP, a Delaware limited partnership, was organized in August 1992 to
acquire and operate the natural gas liquids pipelines of Enron Corp. Through its
three operating limited partnerships, KMEP manages a diversified portfolio of
midstream energy assets. It is the sole owner and operator of three pipeline
systems (the "KMEP Pipeline System"), which transport Natural Gas Liquids
("NGLs"), refined petroleum products, and carbon dioxide ("CO(2)"), and two
modern, high-speed coal terminaling facilities (the "Coal Terminals"). The KMEP
Pipeline System consists of (i) the North System, which transports petroleum
products from South Central Kansas to the Chicago area and various intermediate
points, (ii) the Cypress Pipeline, which transports purity ethane from the NGL
hub in Mont Belvieu, Texas to a major petrochemical producer in Lake Charles,
Louisiana, and (iii) the Central Basin Pipeline, which transports CO(2) to
enhanced oil recovery projects throughout the Permian Basin in West Texas. KMEP
also owns an indirect 25% interest in a Y-grade fractionation facility.
 
   
    On February 14, 1997, the current management of KMEP acquired the stock of
the KM General Partner from Enron Corp. The current management's business
strategy is to operate KMEP as a growth-oriented publicly traded limited
partnership by reducing operating costs, better utilizing and expanding its
asset base, and making selective, strategic acquisitions that are accretive to
KMEP Common Unit holders. See "The Parties--KMEP--Business Strategy."
    
 
    On October 27, 1997, KMEP entered into a letter of intent with Shell Western
E&P Inc. ("Shell Western") to form Shell CO(2) Company, Ltd., as a Delaware
limited partnership ("Shell CO(2) Company"), which will explore, produce, market
and transport CO(2) for enhanced oil recovery throughout the continental United
States. KMEP expects to receive a 20% interest in Shell CO(2) Company by
contributing the Central Basin Pipeline and approximately $25 million in cash.
The Shell CO(2) transaction is subject to certain conditions, including the
execution of a definitive partnership agreement, receipt of consents from
certain lenders and certain required regulatory approvals, and is anticipated to
close in the first quarter of 1998. See "The Parties--KMEP--Central Basin
Pipeline." Under the Purchase Agreement, the Shell CO(2) transaction is subject
to the approval of the Board of Directors of the SF General Partner.
 
    Upon consummation of the Transaction, KMEP will be one of the largest common
carrier pipeline systems in terms of volume of deliveries, barrel miles and
pipeline mileage in the United States, with over 5,000 miles of trunk pipeline
serving 15 states.
<PAGE>
   
    The KM General Partner serves as the sole general partner of KMEP. In
addition to its general partner interest in KMEP, the KM General Partner owns,
as of January 15, 1998, approximately 6.1% of the KMEP Common Units, before
giving effect to the Transaction. KMEP is the approximate 99% limited partner of
each of its operating partnerships and the KM General Partner is the approximate
1% general partner. These operating partnerships consist of: (i) Kinder Morgan
Operating L.P. "A", a Delaware limited partnership ("OLP-A"), which owns most of
the assets relating to the transportation of NGLs, refined petroleum products
and CO(2) and the interest in the NGL fractionation facility; (ii) Kinder Morgan
Operating L.P. "B", a Delaware limited partnership ("OLP-B"), which owns the
Illinois coal terminaling and storage facility; and (iii) Kinder Morgan
Operating L.P. "C", a Delaware limited partnership ("OLP-C"), which owns the
southwest Kentucky coal terminaling and storage facility. OLP-A, OLP-B and OLP-C
are collectively referred to herein as the "KMEP Operating Partnerships." In
connection with the Transaction, KMEP will form Kinder Morgan Operating L.P.
"D", a Delaware limited partnership ("OLP-D"; together with the KMEP Operating
Partnerships, the "KMEP Partnerships"), of which KMEP will be the approximate
99% limited partner and the KM General Partner will be the approximate 1%
general partner. Following the consummation of the Transaction and the Special
Distribution, KMEP will contribute to OLP-D all its interest in the SF Operating
Partnership and OLP-D will be the sole general partner of, and will own a 99.5%
general partner interest in, the SF Operating Partnership and the SF General
Partner will own the .5% Special LP Interest (as defined below).
    
 
    As a result of its 1% general partner interest in KMEP and its approximate
1% general partner interest in each of the KMEP Partnerships, the KM General
Partner will have a 2% economic interest in the assets of KMEP and Santa Fe. In
addition, the KM General Partner is entitled to receive quarterly cash incentive
distributions from KMEP, which increase based on the amount of quarterly cash
distributions paid to holders of the KMEP Common Units. See "Risk Factors--Risks
Associated With KMEP Partnership Agreement and State Partnership
Law--Differences in Cash Distribution Policies" and "Description of KMEP
Partnership Agreement--Cash Distribution Policy."
 
    KMEP's headquarters and executive offices are located at 1301 McKinney
Street, Suite 3450, Houston, Texas 77010 and its telephone number is (713)
844-9500.
 
SANTA FE
 
    Santa Fe is a Delaware limited partnership formed in 1988 to acquire and
operate, through the SF Operating Partnership, the refined petroleum products
pipeline business of Santa Fe Pacific Corporation, a Delaware corporation
("SFC").
 
   
    Santa Fe transports via pipeline refined petroleum products, including
gasoline, diesel fuel and commercial and military jet fuel, primarily for major
petroleum companies, independent refiners, the United States military and
marketers and distributors of such products. Santa Fe also operates 13 truck
loading terminals and provides pipeline service to approximately 44
customer-owned terminals, three commercial airports and 12 military bases. Santa
Fe's pipelines (collectively, the "SF Pipeline System") are: (1) the South Line,
which is composed of two segments, the West Line, which transports products from
Los Angeles to Phoenix and Tucson, Arizona and various intermediate points, and
the East Line, which transports products from El Paso, Texas to Tucson, Phoenix
and various intermediate points; (2) the North Line, which transports products
primarily from the San Francisco Bay area to various cities in northern
California and western Nevada; (3) the Oregon Line, which transports products
between Portland and Eugene, Oregon; and (4) the San Diego Line, which
transports products from Los Angeles to San Diego, California and various
intermediate points. The SF Pipeline System and the KMEP Pipeline System are
referred to as the "Liquids Pipelines." Santa Fe also owns certain other lines
that can be used to connect refinery, terminal or storage facilities to pipeline
or other facilities, some of which are dedicated to use for a specific customer
and some of which have been leased to or are operated by other parties.
    
 
                                       2
<PAGE>
   
    The SF General Partner is the sole general partner of both Santa Fe and the
SF Operating Partnership (collectively, the "Santa Fe Partnerships"). Prior to
the consummation of the Transaction, the SF General Partner has a 2% economic
interest in the assets of Santa Fe as a result of its 1% general partner
interest in Santa Fe and its approximate 1% general partner interest in the SF
Operating Partnership. In addition, prior to the consummation of the
Transaction, the SF General Partner is entitled to receive quarterly cash
incentive distributions from Santa Fe, which increase based on the amount of
quarterly cash distributions paid to holders of Santa Fe Common Units. See "Risk
Factors--Risks Associated With KMEP Partnership Agreement and State Partnership
Law--Differences in Cash Distribution Policies." The SF General Partner also
owns 8,148,148 Santa Fe Common Units, which is approximately the number of Santa
Fe Common Units into which the VREDs are exchangeable under certain

RECORD DATE; COMMON UNITS ENTITLED TO VOTE
 
   
    KMEP.  Holders of record of KMEP Common Units at the close of business on
January 11, 1998, are entitled to notice and to vote at the KMEP Special
Meeting. On such date, there were 14,111,200 KMEP
    
 
                                       3
<PAGE>
Common Units outstanding, each of which will be entitled to vote on each matter
to be acted upon or which may be properly brought before the KMEP Special
Meeting.
 
   
    SANTA FE.  Holders of record of Santa Fe Common Units (other than the SF
General Partner and its affiliates) at the close of business on January 11,
1998, are entitled to notice of and to vote at the Santa Fe Special Meeting. On
such date, there were 10,995,400 Santa Fe Common Units outstanding that were
held by non-affiliates of the SF General Partner, each of which will be entitled
to vote on each matter to be acted upon or which may be properly brought before
the Santa Fe Special Meeting. In addition, there were 8,152,748 Santa Fe Common
Units beneficially owned by the SF General Partner and its affiliates, which
Santa Fe Common Units are not eligible to be voted on the Santa Fe Proposal and
will have no effect on the outcome.
    
 
QUORUM AND VOTE REQUIRED
 
    KMEP.  Holders of a majority of the outstanding KMEP Common Units
represented in person or by proxy will constitute a quorum. Assuming the
presence of a quorum, the affirmative vote of the holders of a majority of the
outstanding KMEP Common Units will be required to approve the KMEP Proposal.
Because the KMEP Proposal requires the approval of the holders of a majority of
the outstanding KMEP Common Units, an abstention or broker non-vote or the
failure to return your proxy will have the same effect as a vote cast AGAINST
the KMEP Proposal.
 
   
    SANTA FE.  Holders of 66 2/3% of the outstanding Santa Fe Common Units
(other than those owned by the SF General Partner and its affiliates)
represented in person or by proxy will constitute a quorum and the affirmative
vote of the holders of at least 66 2/3% of the outstanding Santa Fe Common Units
(excluding Santa Fe Common Units beneficially owned by the SF General Partner
and its affiliates) will be required to approve the Santa Fe Proposal. Because
the Santa Fe Proposal requires the approval of the holders of at least 66 2/3%
of the outstanding Santa Fe Common Units (excluding Santa Fe Common Units
beneficially owned by the SF General Partner and its affiliates), an abstention
or broker non-vote or the failure to return your proxy will have the same effect
as a vote cast AGAINST the Santa Fe Proposal.

                RECOMMENDATIONS AND REASONS FOR THE TRANSACTION
 
KMEP
 
    The Board of Directors of the KM General Partner (i) believes that the terms
of the Transaction are fair to, and in the best interest of, KMEP and the
holders of the KMEP Common Units, (ii) has unanimously approved the Purchase
Agreement, the Transaction, and the other matters anticipated thereby and (iii)
recommends that holders of KMEP Common Units vote FOR approval of the KMEP
Proposal. The Board of Directors of the KM General Partner believes that the
Transaction is in the best interests of the holders of KMEP Common Units for the
following reasons:
 
    1.  The Transaction is expected to result in an increase in both per common
       unit net income and per common unit declared distributions for holders of
       KMEP Common Units;
 
    2.  Significant cost savings are expected to be achieved by combining the
       operations of the two partnerships;
 
    3.  Opportunities to solidify customer relationships and enhance revenue
       growth are expected to be improved as a result of the Transaction;
 
    4.  The Transaction is expected to increase the number of acquisition
       opportunities available to KMEP in the future; and
 
                                       4
<PAGE>
    5.  The financial condition of KMEP is expected to be enhanced as a result
       of the Transaction, thereby facilitating the funding of new growth
       initiatives.
 
SANTA FE
 
   
    The Board of Directors of the SF General Partner (i) believes that the terms
of the Transaction are in the best interests of the holders of Santa Fe Common
Units and (ii) has unanimously approved the Purchase Agreement, the Transaction
and the other matters contemplated thereby, and recommends that holders of Santa
Fe Common Units vote FOR approval of the Santa Fe Proposal.
    
 
    The SF General Partner believes that the Transaction is in the best
interests of holders of Santa Fe Common Units for the following principal
reasons:
 
    1.  The Exchange Ratio provides the holders of Santa Fe Common Units with a
       significant premium over the market price of their Santa Fe Common Units
       prior to the announcement of the Transaction;
 
   
    2.  The Transaction is expected to result in an increased quarterly
       distribution to holders of Santa Fe Common Units who become holders of
       KMEP Common Units;
    
 
   
    3.  As holders of KMEP Common Units, the holders of Santa Fe Common Units
       will continue to hold an equity security that will entitle them to
       participate in the future of a combined business committed to growth;
    
 
   
    4.  As holders of KMEP Common Units, the holders of Santa Fe Common Units
       will hold an investment in a larger and more broadly diversified
       business;
    
 
   
    5.  Significant cost savings are expected to be achieved by combining the
       operations of the two partnerships;
    
 
   
    6.  The management of KMEP has demonstrated an intent to aggressively seek
       appropriate opportunities to grow and to increase the total return to
       holders of KMEP Common Units; and
    
 
   
    7.  Given the reputation of KMEP and its management for aggressive growth,
       KMEP Common Units present a potential for trading at higher multiples of
       cash flow than Santa Fe Common Units, as well as a greater potential for
       appreciation in price.
    
 
   
    A special commitee of directors deemed by the Board of Directors to be
independent of the interests of the SF General Partner in the Transaction (the
"Special Committee") has considered the benefits presented by the proposed
Transaction and weighed them against the risks associated with the Transaction,
and the Special Committee has unanimously concluded that the Transaction is in
the best interests of the holders of Santa Fe Common Units. Holders of Santa Fe
Common Units are urged to read in full the discussion of the factors considered
by the Special Committee in reaching its determination set forth under "The
Transaction--Reasons for the Transaction--Recommendations of the General
Partners--Santa Fe Special Committee" and the discussion of the risks associated
with the Transaction set forth under "Risk Factors."

"The Transaction--Opinions of Financial Advisors--Santa Fe."
    
 
                   THE TRANSACTION AND THE PURCHASE AGREEMENT
 
THE PURCHASE AGREEMENT
 
   
    GENERAL.  Pursuant to the Purchase Agreement (i) KMEP will acquire from
Santa Fe substantially all of the limited partner interests in the SF Operating
Partnership in exchange for a number of KMEP Common Units such that, upon the
liquidation of Santa Fe, the holders of Santa Fe Common Units shall be
distributed a right to receive 1.39 KMEP Common Units for each outstanding Santa
Fe Common Unit (which will result in the issuance to the public holders of Santa
Fe Common Units of an aggregate of approximately 15.3 million KMEP Common Units
and the issuance to the SF General Partner of an aggregate of approximately 11.3
million KMEP Common Units) and (ii) OLP-D (as the successor general partner of
Santa Fe) will acquire the general partner interest in Santa Fe from the SF
General Partner in exchange for $84.4 million in cash and will be admitted as
the new general partner of Santa Fe. As a result of the Transaction, the holders
of the VREDs will have the right to exchange the VREDs for the KMEP Common Units
to be received by the SF General Partner. See "The Transaction--VREDs."
Immediately following such purchases, OLP-D (as successor general partner of
Santa Fe) will liquidate Santa Fe and, as a result of such liquidation, (a) each
former Santa Fe Common Unit will represent the right to receive (subject to
certain provisions with respect to fractional KMEP Common Units) 1.39 KMEP
Common Units and (b) OLP-D will receive the remaining limited partner interest
in the SF Operating Partnership and any remaining assets of Santa Fe.
    
 
   
    AMENDMENTS TO SANTA FE PARTNERSHIP AGREEMENT.  In connection with the
Transaction and the dissolution and liquidation of Santa Fe, Santa Fe will adopt
the Santa Fe Partnership Agreement Amendments. See "The Purchase
Agreement--Liquidation of Santa Fe--Amendment of the Santa Fe Partnership
Agreement" and Annex E in the accompanying Annex Volume which accompanies and
forms a part of this Joint Proxy Statement/Prospectus.
    
 
    AMENDMENTS TO SF OPERATING PARTNERSHIP AGREEMENT.  The partnership agreement
of the SF Operating Partnership will be amended and restated to facilitate the
Transaction and to reflect the conversion of the 99% limited partner interest in
the SF Operating Partnership to a 99% general partner interest to be owned by
OLP-D and the conversion of the SF General Partner's approximate 1% general
partner interest in the SF Operating Partnership to the Special LP Interest. The
partnership agreement of the SF
 
                                       6
<PAGE>
Operating Partnership will also be amended to provide that the rights of OLP-D,
as general partner of the SF Operating Partnership, and the KM General Partner,
as general partner of OLP-D, will be subrogated to the rights of any holder of
Indemnified Debt (as defined herein) to the extent that either entity acting as
a general partner of the SF Operating Partnership or OLP-D, as applicable, made
any payment with respect to such Indemnified Debt. The SF General Partner will
under certain circumstances be subrogated to the rights of OLP-D, as general
partner of the SF Operating Partnership, and the KM General Partner, as general
partner of OLP-D, against the SF Operating Partnership if the SF General Partner
is required to make any payment in respect of the Debt Indemnity (as defined
herein). See "The Purchase Agreement-- Liquidation of Santa Fe--Amendment of the
SF Operating Partnership Agreement" and "The Purchase
Agreement--Indemnification--Santa Fe."
 
    SPECIAL DISTRIBUTION; PUT/CALL RIGHTS.  Immediately following the Closing,
approximately one-half of the Special LP Interest will be redeemed for $5.8
million in cash (the "Special Distribution"). As a result of the Special
Distribution, OLP-D's general partner interest in the SF Operating Partnership
will be increased to 99.5% and the Special LP Interest will be reduced to .5%.
At any time after January 1, 1999, the SF General Partner may require the SF
Operating Partnership to purchase the SF General Partner's remaining .5% Special
LP Interest on the terms and conditions described herein. OLP-D may at any time
redeem the SF General Partner's remaining .5% Special LP Interest on the terms
and conditions described herein. See "The Purchase Agreement--Put Right" and
"The Purchase Agreement--Call Right."
 
   
    EXCHANGE OF SANTA FE COMMON UNITS FOR KMEP COMMON UNITS AND/OR FRACTIONAL
UNIT PAYMENTS.  As a result of the liquidation of Santa Fe, each former Santa Fe
Common Unit will represent the right to receive 1.39 KMEP Common Units (with
cash in lieu of fractional KMEP Common Units). The issuance of KMEP Common Units
to holders of former Santa Fe Common Units will be made pursuant to the
procedures described under "The Purchase Agreement--Acquisition of Santa Fe;
Issuance of KMEP Common Units." No certificates representing fractional
interests in KMEP Common Units will be issued in exchange for certificates of
Santa Fe Common Units, but holders of such certificates will receive a cash
payment equal to the holder's fractional interest in KMEP Common Units
multiplied by the average high and low price of KMEP Common Units on the trading
day prior to the Closing. See "The Purchase Agreement--Liquidation of Santa Fe"
and "The Purchase Agreement--Liquidation of Santa Fe--Fractional Units." The
NYSE has approved for listing on the NYSE the KMEP Common Units to be issued in
connection with the Transaction subject to unitholders' approval of the matters
to be voted on at the Special Meetings and official notice of issuance.
    
 
    CONDITIONS OF TRANSACTION.  Consummation of the Transaction is subject to
the satisfaction of a number of conditions, including without limitation, the
approval of the Transaction by the California Public Utilities Commission
("CPUC"), which conditions are discussed more fully in this Joint Proxy
Statement/ Prospectus under "The Purchase Agreement--Conditions."
 
    INDEMNIFICATION.  From and after the Closing, KMEP will (and will cause the
SF Operating Partnership to) indemnify the SF General Partner, SF Holdings and
their affiliates from any loss relating to (i) Santa Fe or the SF Operating
Partnership (whether prior to or after Closing), (ii) the VREDs (except for
taxable gains), (iii) certain severance costs and (iv) certain reimbursable
expenses under the Santa Fe Partnership Agreement.
 
   
    From and after the Closing, (i) the SF General Partner will indemnify the KM
General Partner and OLP-D from any loss relating to payments made with respect
to the Santa Fe First Mortgage Notes and any refinancing, refunding or
replacement thereof up to $190 million (the "Debt Indemnity"), and (ii) the SF
General Partner will indemnify the KM General Partner, KMEP, OLP-D and their
affiliates from any losses relating to any claim for money damages by a limited
partner of Santa Fe relating to the fairness of the Transaction to such limited
partners and from any losses relating to (a) a material breach of its
representation regarding title to the securities to be transferred, (b) any
taxes assessed due to the liquidation of Santa Fe, (c) any claim by any holder
of the VREDs or the Santa Fe First Mortgage Notes or
    
 
                                       7
<PAGE>
by any lender under the Santa Fe Credit Agreement, to the extent relating to any
act or omission of the SF General Partner and such claim is asserted prior to
Closing, (d) certain expenses and fees of the SF General Partner, (e) certain
employee benefits and (f) certain excluded reimbursement items. See "The
Purchase Agreement--Indemnification."
 
   
    SEVERANCE OBLIGATIONS.  Generally, KMEP is responsible for all severance
costs above $4.5 million related to the SF General Partner's employees; provided
that the SF General Partner will also be responsible for up to an additional $1
million relating to certain disputed severance obligations.
    
 
    CERTAIN COVENANTS.  Among other covenants applicable to the parties, the SF
General Partner and Santa Fe agreed that except as described below, they would
(i) terminate all discussions and negotiations with others for any transaction
similar to the Transaction, (ii) not directly or indirectly solicit, initiate or
encourage discussions or negotiations with any other person or entity that may
reasonably be expected to lead to such a similar transaction, (iii) not enter
into any agreement relating to or make any statement in support of such similar
transaction and (iv) subject to the fiduciary duties of the SF General Partner
and its Board of Directors and the Special Committee, not withdraw or qualify
their recommendation of the Transaction.
 
    The SF General Partner and the SF Operating Partnership may take action
otherwise prohibited by the above paragraph if (i) the initial contact is not
made in violation of the above paragraph, (ii) the Special Committee determines,
in its good faith judgment, that any otherwise prohibited action may lead to a
transaction that may be more beneficial than the Transaction, taken as a whole,
to the holders of the Santa Fe Common Units, other than the SF General Partner
and its affiliates, and (iii) the Special Committee determines that the failure
to take such action would be inconsistent with the SF General Partner's
fiduciary duties to holders of Santa Fe Common Units.
 
    TERMINATION OF PURCHASE AGREEMENT.  The Purchase Agreement is subject to
termination by:
 
    (a) THE KM GENERAL PARTNER AND THE SF GENERAL PARTNER, upon their mutual
       written agreement;
 
    (b) THE SF GENERAL PARTNER, (i) if either KMEP or the KM General Partner
       fails to perform in any material respect its respective agreements
       contained in the Purchase Agreement or materially breaches any of its
       representations, warranties or covenants contained in the Purchase
       Agreement (which failure or breach would relieve Santa Fe, the SF General
       Partner and SF Holdings of their obligations to close the Transaction),
       if such breach cannot be cured prior to the Closing or is not cured
       within 45 days after the SF General Partner has given notice of such
       breach; (ii) upon the occurrence of any event that would reasonably be
       expected to have a material adverse effect on KMEP; (iii) acting through
       the Special Committee, if the Special Committee determines that a
       Possible Alternative (as defined herein) would constitute a Superior
       Transaction (as defined herein); or (iv) if the Board of Directors of the
       KM General Partner withdraws, modifies or changes in a manner adverse to
       Santa Fe, the SF Operating Partnership and SF Holdings its recommendation
       that the holders of KMEP Common Units approve the issuance of KMEP Common
       Units on the terms and conditions in the Purchase Agreement;
 
    (c) THE KM GENERAL PARTNER, (i) if any of Santa Fe, the SF General Partner
       or SF Holdings fails to perform in any material respect its respective
       agreements contained in the Purchase Agreement or materially breaches any
       of its representations, warranties or covenants contained in the Purchase
       Agreement (which failure or breach would relieve KMEP and the KM General
       Partner of their obligations to close the Transaction), if such breach
       cannot be cured prior to the Closing or is not cured within 45 days after
       the KM General Partner has given notice of such breach; (ii) upon the
       occurrence of any event that would reasonably be expected to have a
       material adverse effect on Santa Fe or the SF Operating Partnership; or
       (iii) if the Board of Directors of the SF General Partner or the Special
       Committee withdraws, modifies or changes in a manner
 
                                       8
<PAGE>
       adverse to KMEP its recommendation that the holders of Santa Fe Common
       Units approve the Transaction; or
 
   
    (d) EITHER THE KM GENERAL PARTNER OR THE SF GENERAL PARTNER, (i) if there is
       any order of any court or governmental or regulatory agency which
       prohibits or restrains Santa Fe, the SF Operating Partnership, SF
       Holdings, KMEP or the KM General Partner from consummating the
       Transaction; (ii) if the Closing has not occurred by March 16, 1998;
       subject to extension to June 30, 1998, if additional time is required to
       obtain the approval of the California Public Utilities Commission; (iii)
       if the matters submitted for approval at the Special Meetings are not
       approved; or (iv) if the average of the daily high and low trading prices
       of KMEP Common Units on the NYSE for any 20 consecutive trading days is
       less than $31.32 or greater than $46.98 (the Special Committee may also
       terminate the Purchase Agreement pursuant to this clause (iv)).
    
 
See "The Purchase Agreement--Termination." Upon termination of the Purchase
Agreement as described in clause (b)(iii), (b)(iv) or (c)(iii) above, the SF
General Partner shall pay KMEP's actual third party expenses arising out of the
Transaction up to a maximum of $2.5 million.
 
    AMENDMENTS OF PURCHASE AGREEMENT AND WAIVER.  The Purchase Agreement may not
be altered, modified or amended except pursuant to a written instrument signed
by the party to be bound. The failure of any party to exercise any right or
remedy under the Purchase Agreement will not be deemed or constitute a waiver of
such right or remedy in the future.
 
                                     VREDS
 
   
    Each $1,000 principal amount of VREDs is currently exchangeable into 37.2093
Santa Fe Common Units upon the occurrence of certain events (i.e., the VREDs may
be exchanged in the aggregate for substantially all of the 8,148,148 Santa Fe
Common Units owned by the SF General Partner). As a result of the Transaction,
the VREDs are exchangeable for the KMEP Common Units for which Santa Fe Common
Units will be exchanged pursuant to this Joint Proxy Statement/Prospectus.
Accordingly, each $1,000 principal amount of VREDs will become exchangeable for
51.720927 KMEP Common Units (which would result in the issuance of an aggregate
of approximately 11.3 million KMEP Common Units if the VREDs are fully
exchanged). KMEP has agreed to cause OLP-D to perform all obligations regarding
the VREDs for the account of SF Holdings from and after the Closing. Any taxable
gains related to the satisfaction and discharge of the VREDs will be for the
account of the SF General Partner or SF Holdings, as applicable. At Closing,
certificates formerly representing Santa Fe Common Units held by the SF General
Partner will be placed in escrow. OLP-D on behalf of SF Holdings will commence
an exchange offer within 45 to 50 days after the Closing (the "VRED Exchange
Offer") in accordance with the terms of the Indenture dated as of September 13,
1990 between SF Holdings and Security Pacific National Bank, as trustee (the
"VRED Indenture"). Ninety days after Closing, any VREDs tendered in the VRED
Exchange Offer will be exchanged for the applicable number of KMEP Common Units.
Subject to market conditions, KMEP intends to commence an underwritten public
offering of newly issued KMEP Common Units for its own account following the
expiration of the VRED Exchange Offer. Any holder of VREDs who exchanges VREDs
pursuant to the VRED Exchange Offer will be entitled to participate, as a
selling unitholder, in this offering subject to such holder's execution of the
appropriate documents required by the managing underwriter and sharing of the
fees and expenses of the offering on a pro rata basis. To the extent that VREDs
are not delivered for exchange, the Santa Fe Common Units into which the VREDs
were exchangeable (and representing the right to receive 1.39 KMEP Common Units
per Santa Fe Common Unit) will be canceled. Any VREDs not delivered for exchange
become due and payable in full in cash at par, plus accrued and unpaid interest
thereon, on the 90th day after Closing. Although it does not currently intend to
do so, pursuant to the VRED Indenture, KMEP has the option to exchange the VREDs
for cash equal to the value of the VREDs surrendered in lieu of KMEP Common
Units. The value of the VREDs will be computed as described under "The
Transaction--VREDs." See "Risk Factors--Certain Risks

                               KMEP LOAN FACILITY
    
 
   
    KMEP has obtained a commitment letter from Goldman Sachs Credit Partners
L.P., as lead arranger, and First Union Capital Markets Corp., as co-arranger,
for a $300 million revolving credit facility (the "KMEP Loan Facility"). KMEP
intends to use the net proceeds from the KMEP Loan Facility to fund (i) the
refinancing of approximately $133.8 million of existing indebtedness of OLP-A
and OLP-B, including the payment of the make-whole premium on the KMEP First
Mortgage Notes (the "Refinanced Indebtedness"), (ii) OLP-D's acquisition of the
general partner interest in Santa Fe from the SF General Partner for $84.4
million in cash, (iii) the $25 million cash contribution to be made by KMEP to
Shell CO(2) Company, (iv) the payment at par of any VREDs not tendered in the
VRED Exchange Offer, (v) the fees, costs and expenses of the Transaction
(estimated to be approximately $13 million) and (vi) general working capital and
other general partnership purposes. Borrowings under the KMEP Loan Facility are
limited to $175 million prior to the Closing. Interest on loans under the KMEP
Loan Facility will accrue, at KMEP's option, at a floating rate equal to either
First Union National Bank's base rate (but not less than the Federal Funds Rate
plus .5% per annum) or LIBOR plus a margin that will vary from .75% to 1.5% per
annum, depending upon the ratio of KMEP's Funded Indebtedness to Cash Flow (each
as defined in the KMEP Loan Facility). Interest on advances will generally be
payable quarterly.
    
 
   
    KMEP and OLP-B will be co-borrowers under the KMEP Loan Facility. The
obligations of KMEP under the KMEP Loan Facility will be guaranteed by the KMEP
Partnerships and each other Restricted Subsidiary (as defined in the KMEP Loan
Facility) of KMEP (other than the SF Operating Partnership). KMEP will guarantee
the obligations of OLP-B under the KMEP Loan Facility. The KMEP Loan Facility
initially will be secured by, among other things, a first priority lien on (i)
KMEP's limited partner interests in the KMEP Partnerships; (ii) all of the
assets of OLP-D (including its general partner interest in the SF Operating
Partnership), (iii) KMEP's ownership interests in the fractionator and Shell
CO(2) Company and (iv) intercompany notes to be executed by the KMEP
Partnerships in favor of KMEP for loan proceeds lent to them by KMEP. If KMEP
fails to maintain certain financial ratios, then each of the KMEP Operating
Partnerships will secure its intercompany note with its assets.
    
 
                           CLOSING OF THE TRANSACTION
 
   
    The closing (the "Closing") shall occur on or before the third business day
following the satisfaction of the conditions set forth in the Purchase Agreement
or such other place, date and time as mutually agreed upon by the parties to the
Purchase Agreement (the "Closing Date").
    
 
                              ACCOUNTING TREATMENT
 
    The Transaction will be accounted for by KMEP under the purchase method of
accounting. Under this method, the reported book value of the assets and
liabilities acquired from Santa Fe will be increased or decreased to their fair
market value on the Closing Date and goodwill will be recorded to the extent
that the purchase price exceeds the fair market value of the net assets. This
goodwill, if any, will be amortized by KMEP over a 40-year period or other
acceptable period for accounting purposes, but will not be amortizable for tax
purposes. See "Material Federal Income Tax Considerations--Tax Consequences of
Holding KMEP Common Units--Section 197 Intangibles."
 
                              NO APPRAISAL RIGHTS
 
    Holders of Santa Fe Common Units are not entitled to any rights of appraisal
or similar rights of dissenters under the Delaware Revised Uniform Limited
Partnership Act (the "Delaware Act") or the Santa Fe Partnership Agreement in
connection with the Transaction. Holders of KMEP Common Units
 
                                       10

are not entitled to any rights of appraisal or similar rights of dissenters
under the Delaware Act or the KMEP Partnership Agreement in connection with the
Transaction.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
    THE TAX CONSIDERATIONS ASSOCIATED WITH THE TRANSACTION AND AN INVESTMENT IN
KMEP TO A PARTICULAR HOLDER OF SANTA FE COMMON UNITS OR TO A PRE-TRANSACTION
HOLDER OF KMEP COMMON UNITS WILL DEPEND IN PART ON SUCH HOLDER'S OWN TAX
CIRCUMSTANCES. MANY OF THE TAX CONSIDERATIONS APPLICABLE TO A PRE-TRANSACTION
KMEP COMMON UNIT HOLDER OR A FORMER SANTA FE COMMON UNIT HOLDER ARE SUBJECT TO
UNCERTAINTY AND MAY DEPEND ON SUCH UNIT HOLDER'S INDIVIDUAL TAX STATUS AND
CIRCUMSTANCES. ACCORDINGLY, EACH SUCH HOLDER IS STRONGLY URGED TO CONSULT A TAX
ADVISOR CONCERNING THE FEDERAL, STATE AND LOCAL TAX CONSIDERATIONS OF THE
TRANSACTION AND AN INVESTMENT IN KMEP COMMON UNITS.
 
   
    The following is a summary of certain federal income tax considerations of
the Transaction and of acquiring, owning and disposing of KMEP Common Units. The
following discussion is based in part upon the opinions of Morrison & Hecker
L.L.P., counsel to the KM General Partner and KMEP ("Morrison & Hecker"), and
Mayer, Brown & Platt, counsel to Santa Fe and the SF General Partner ("Mayer,
Brown & Platt"), described in "Material Federal Income Tax Considerations." This
summary, and particularly the opinions of counsel with respect thereto, are
qualified by the discussion in "Material Federal Income Tax Considerations."
    
 
   
OPINION OF MAYER, BROWN & PLATT REGARDING THE TRANSACTION
    
 
   
    Mayer, Brown & Platt has rendered its opinion to Santa Fe to the effect
that: (i) subject to the uncertainty involving the treatment of the Fractional
Unit Payments as described under "Material Federal Income Tax
Considerations--Tax Consequences of the Exchange and Distributions--Disguised
Sale Rules," Santa Fe will not recognize income, gain, loss or deduction as a
result of the transfer of limited partner interests in SF Operating Partnership
to KMEP in exchange for rights to receive KMEP Common Units or as a result of
such KMEP Common Units being distributed to, and received by, Santa Fe Common
Unit holders; (ii) subject to the uncertainty involving the treatment of the
Fractional Unit Payments, Santa Fe Common Unit holders will not recognize
income, gain, loss or deduction (A) on the transfer of limited partner interests
in the SF Operating Partnership by Santa Fe to KMEP in exchange for rights to
receive KMEP Common Units, (B) upon the receipt of the right to receive KMEP
Common Units pursuant to the liquidation of Santa Fe or the receipt of such KMEP
Common Units, (C) upon the receipt of a Fractional Unit Payment from KMEP,
except to the extent that the Fractional Unit Payment received by any such
holder exceeds such holder's tax basis in KMEP Common Units, or (D) otherwise as
a result of the Transaction; (iii) the tax basis of the KMEP Common Units
received by a Santa Fe Common Unit holder will be equal to the adjusted tax
basis of such holder's Santa Fe Common Units, reduced, but not below zero, by
the amount of the Fractional Unit Payment received, if any; and (iv) based upon
a representation of the SF General Partner that there has not been a
constructive termination of Santa Fe for federal income tax purposes since 1988,
the holding period of the KMEP Common Units in the hands of the Santa Fe Common
Unit holders will be deemed to have commenced no later than January 1, 1989,
except to the extent the value of the SF Operating Partnership is attributable
to Section 751 assets other than depreciation recapture (e.g. unrealized
receivables, inventory items and capital improvements not held by the SF
Operating Partnership for more than 12 months), in which case the holding period
of the KMEP Common Units received by a Santa Fe Common Unit holder attributable
to such Section 751 assets will begin on the day following the date of the
Transaction. The SF General Partner believes that an insignificant portion of
the value of the SF Operating Partnership is attributable to such items. See
"Material Federal Income Tax Considerations--Tax Consequences of the Exchange
and Distributions-- Disguised Sales Rules."
    
 
                                       11
<PAGE>
   
OTHER TAX CONSEQUENCES OF THE TRANSACTION
    
 
   
    As a result of the liquidation of Santa Fe, Santa Fe will terminate and
Santa Fe's taxable year will close on the Closing Date. Santa Fe Common Unit
holders with a fiscal tax year may realize a bunching of income (I.E., more than
12 months of partnership income realized in a partner's single tax year) as a
result of the liquidation of Santa Fe. The Transaction will result in a
constructive termination of the SF Operating Partnership and is likely to result
in a constructive termination of KMEP, with the result that the depreciation
deductions with respect to each partnership's assets will be deferred. In
addition, a constructive termination of KMEP would cause a KMEP Common Unit
holder with a fiscal year to realize a bunching of income (i.e., more than
twelve months of partnership income realized in a partner's single tax year).
See "Material Federal Income Tax Considerations--Tax Consequences of the
Transaction to Both KMEP and Santa Fe Common Unit Holders--Constructive
Termination of Partnership."
    
 
   
    The federal income tax consequences described above are dependent upon both
KMEP and Santa Fe being classified as partnerships for federal income tax
purposes. While Morrison & Hecker has opined that KMEP is classified as a
partnership for federal income tax purposes and Mayer, Brown & Platt has opined
that Santa Fe is classified as a partnership for federal income tax purposes, no
rulings have been requested from the Internal Revenue Service (the "IRS"), and
no assurance can be given that the IRS will not successfully assert that either
KMEP or Santa Fe is not properly classified as a partnership for federal income
tax purposes. See "Risk Factors--Tax Risks--Tax Treatment of Transaction
Dependent on Partnership Status" and "Material Federal Income Tax
Considerations--General Features of Partnership Taxation--Partnership Status."
    
 
   
    This summary and the opinions stated herein are based on and subject to
certain representations and assumptions as described in "Material Federal Income
Tax Considerations--Tax Consequences of the Exchange and Distributions."
    
 
PARTNERSHIP STATUS
 
    In the opinion of Morrison & Hecker, under current law, and based on certain
representations of the KM General Partner and the SF General Partner and
partially in reliance on the opinion of Mayer, Brown & Platt as to Santa Fe's
and the SF Operating Partnership's status as partnerships, KMEP is and will
continue to be classified for federal income tax purposes as a partnership, and
the beneficial owners of KMEP Common Units will be considered limited partners
in KMEP. Accordingly, KMEP will pay no federal income taxes, and KMEP Common
Unit holders will be required to report on their respective federal income tax
returns their respective shares of KMEP's income, gains, losses, deductions and
credits, even if cash is not distributed by KMEP. In general, cash distributions
to a holder of KMEP Common Units will not be taxable unless, and to the extent
that, they exceed such holder's tax basis in KMEP Common Units. See "Material
Federal Income Tax Considerations--General Features of Partnership
Taxation--Partnership Status."
 
    KMEP's assets will include its interest in OLP-A, which owns all of the
capital stock of a corporation that owns an indirect interest in the Mont
Belvieu Fractionator. As a corporation, it will be subject to entity-level
taxation for federal and state income tax purposes. The KM General Partner
estimates that such corporation will not generate a material amount of taxable
income; however, cash distributions by KMEP to KMEP Common Unit holders
attributable to such income will generally be treated as taxable dividends.
 
TREATMENT OF PARTNERSHIP DISTRIBUTIONS
 
   
    In general, except for certain gross income allocations to the KM General
Partner necessary to support incentive distributions of Available Cash (see
"Description of KMEP Partnership Agreement-- Cash Distribution Policy"), annual
income and loss of KMEP will be allocated to the KM General Partner and the
holders of KMEP Common Units for each taxable year in accordance with their
respective
    
 
                                       12
<PAGE>
percentage interests in KMEP, as determined annually and prorated on a monthly
basis and subsequently apportioned among the holders of KMEP Common Units of
record as of the opening of the first business day of the month to which they
relate, even though holders of KMEP Common Units may dispose of their KMEP
Common Units during the month in question. In addition, a holder of KMEP Common
Units will be required to take into account, in determining federal income tax
liability, such holder's share of income generated by KMEP for each taxable year
whether or not cash distributions are made to such holder. As a consequence, the
share of taxable income of such holder (and possibly the income tax payable by
such holder with respect to such income) may exceed the cash, if any, actually
distributed to such holder. See "Material Federal Income Tax
Considerations--General Features of Partnership Taxation."
 
INCREASE IN TAXABLE INCOME
 
   
    The amount of taxable income realized by a KMEP Common Unit holder will be
dependent upon a number of factors including: (a) the taxable income realized by
KMEP, which may vary significantly based on the operations of the KMEP
Partnerships; (b) any gain realized by a sale of assets which represents
unrealized gain in assets as of the time of the Transaction and the resulting
allocation of such gain to either the pre-Transaction KMEP Common Unit holders
or the former Santa Fe Common Unit holders, depending upon the asset being sold;
(c) the amount and timing of Curative Allocations (as defined herein) available
to pre-Transaction KMEP Common Unit holders and former Santa Fe Common Unit
holders attributable to the allocation of unrealized gain inherent in SF
Operating Partnership assets and KMEP assets as of the date of the Transaction
between and among asset classes, including intangibles, if any, which may not be
amortizable; and (d) the amount of the basis adjustment available to a KMEP
Common Unit holder based on the purchase price for such Unit holder's Santa Fe
or KMEP Common Units. See "Material Federal Income Tax Considerations--Tax
Consequences of KMEP Common Unit Ownership--Factors Affecting Taxable Income."
The ratio of taxable income to cash distributions will be dependent on the
previously mentioned factors as well as other factors such as: (i) the KM
General Partner's policy for funding capital improvements; (ii) the cash flow
generated by operations; and (iii) other needs for cash flow which may diminish
the amount available for distribution. The amounts of depreciation deductions
and net Curative Allocations available to a KMEP Common Unit holder may be major
contributing factors in determining the differences in the ratio of taxable
income to cash distributions which will be realized by any KMEP Common Unit
holder following the Transaction. The constructive terminations of the SF
Operating Partnership and KMEP as a result of the Transaction will restart the
depreciable lives for the assets held which will defer the depreciation
attributable to common inside tax basis of such assets and will establish the
depreciable period for any net Curative Allocations attributable to such assets
as well as defer depreciation attributable to the purchase price of a KMEP or
Santa Fe Unit. In addition, most of the SF Operating Partnership and KMEP assets
are in asset classes which utilize a mid-year convention for the year of the
acquisition and disposition of such assets. Accordingly, in 1998, the KM General
Partner estimates that the effect of such constructive terminations and
depreciation conventions will be a reduction of 50% in the depreciation
deductions and net Curative Allocations available to former Santa Fe Common Unit
holders and pre-Transaction KMEP Common Unit holders. The KM General Partner
estimates there will be no material adverse effect on depreciation deductions
and Curative Allocations for the years 1999 and 2000. See "Material Federal
Income Tax Considerations--Tax Consequences of KMEP Common Unit
Ownership--Factors Affecting Taxable Income."
    
 
BASIS OF KMEP COMMON UNITS
 
    A KMEP Common Unit holder's tax basis for a KMEP Common Unit following the
Transaction will generally be the amount originally paid for the KMEP Common
Unit, or in the case of former Santa Fe Common Unit holders, the amount
originally paid for the Santa Fe Common Units, increased by such holder's share
of KMEP's (or Santa Fe's) income and nonrecourse liabilities, if any, and
decreased by KMEP's (or Santa Fe's) losses and distributions.
 
                                       13
<PAGE>
LIMITATIONS ON DEDUCTIBILITY OF PARTNERSHIP LOSSES
 
    Under the passive loss limitations, losses generated by KMEP, if any, will
only be available to offset future income generated by KMEP and cannot be used
to offset income from other activities including passive activities or
investments. There is uncertainty as to whether KMEP will be deemed to be a
continuation of Santa Fe for purposes of the passive activity loss rules. Thus
it is not clear whether a Santa Fe Common Unit holder with losses from Santa Fe
taxable periods prior to the Transaction could use such losses (a) to offset
such holder's allocable share of KMEP income; (b) to offset only KMEP income
from the SF Operating Partnership activities; or (c) only as additional
deductions upon sale of such KMEP Common Units. Unused losses may be deducted
when a holder of KMEP Common Units disposes of such holder's KMEP Common Units
in a fully taxable transaction with an unrelated party. Net passive income from
KMEP may be offset by any unused losses related to KMEP that a holder of KMEP
Common Units has carried over from prior years, but not by losses from other
passive activities including losses from other publicly traded partnerships. See
"Material Federal Income Tax Considerations--Tax Consequences of KMEP Common
Unit Ownership--Limitations on Deductibility of KMEP Losses."
 
SECTION 754 ELECTION
 
   
    Each of KMEP, the KMEP Operating Partnerships and the SF Operating
Partnership has made and will make, as necessary, and maintain the election
provided for by Section 754 of the Internal Revenue Code of 1986, as amended
(the "Code"). This election generally permits a holder of KMEP Common Units to
calculate cost recovery and depreciation deductions with respect to each asset
of KMEP and the KMEP Operating Partnerships by reference to the portion of such
KMEP Common Unit holder's purchase price attributable to each such asset of
KMEP, rather than by reference to KMEP's tax basis in its assets. See "Material
Federal Income Tax Considerations--Tax Treatment of Operations--Section 754."
    
 
DISPOSITION OF KMEP COMMON UNITS
 
    A KMEP Common Unit holder who sells KMEP Common Units will recognize gain or
loss equal to the difference between the amount realized (including the
reduction in such Common Unit holder's share of nonrecourse liabilities, if any,
included in basis) and such holder's adjusted basis in such KMEP Common Units. A
portion of the consideration realized (whether or not representing gain) may be
ordinary income. See "Material Federal Income Tax Considerations--Disposition of
KMEP Common Units."
 
   
OWNERSHIP OF KMEP COMMON UNITS BY TAX-EXEMPT ORGANIZATIONS AND CERTAIN OTHER
  INVESTORS
    
 
    An investment in KMEP Common Units by tax-exempt organizations (including
individual retirement accounts ("IRAs") and other retirement plans), regulated
investment companies and foreign persons raises issues unique to such persons.
Virtually all of the income related to KMEP derived by a tax-exempt organization
holding KMEP Common Units will be unrelated business taxable income, and thus
will be taxable to such organization; no significant amount of KMEP's gross
income will be qualifying income for purposes of determining whether a KMEP
Common Unit holder will qualify as a regulated investment company; and a KMEP
Common Unit holder who is a nonresident alien, foreign corporation or other
foreign person will be regarded as being engaged in a trade or business in the
United States as a result of ownership of a KMEP Common Unit and thus will be
required to file federal income tax returns and to pay tax on such KMEP Common
Unit holder's share of KMEP taxable income. See "Material Federal Income Tax
Considerations--Tax Exempt Organizations and Certain Other Investors."
 
TAX SHELTER REGISTRATION
 
    The Code generally requires that "tax shelters" be registered with the
Secretary of the Treasury. The investment objectives of KMEP are to operate KMEP
at a profit and to make cash distributions to holders
 
                                       14
<PAGE>
of KMEP Common Units. Nevertheless, KMEP has registered as a tax shelter with
the IRS. ISSUANCE OF THE REGISTRATION NUMBER DOES NOT INDICATE THAT AN
INVESTMENT IN KMEP OR THE CLAIMED TAX BENEFITS HAVE BEEN REVIEWED, EXAMINED OR
APPROVED BY THE IRS. See "Material Federal Income Tax
Considerations--Administrative Matters--Registration as a Tax Shelter."
 
STATE AND LOCAL TAX CONSIDERATIONS
 
    Each holder of KMEP Common Units may be subject to income, estate or
inheritance taxes in states and localities in which KMEP owns property or does
business, as well as in such holder's own state or locality. Following
consummation of the Transaction, KMEP will conduct business in 15 states:
Arizona, California, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana,
Missouri, Nebraska, Nevada, New Mexico, Oregon, Texas and Wyoming. See "Material
Federal Income Tax Considerations--Other Taxes."
 
   
                INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION
    
 
   
    Certain officers, directors and affiliates of the SF General Partner and the
KM General Partner have a direct or indirect interest in the consummation of the
Transaction and the other matters contemplated by the Purchase Agreement by
virtue of common unit ownership, ownership of a general partner or expected
compensation or severance benefits.
    
 
   
OFFICERS AND DIRECTORS OF THE SF GENERAL PARTNER
    
 
   
    Under employment agreements and certain employee and director benefit plans
each of the following officers of the SF General Partner--Irvin Toole, Jr.,
Chairman, President and Chief Executive Officer, John M. Abboud, Senior Vice
President-Operations and Technical Services, Robert L. Edwards, Director and
Senior Vice President-Business Development, Barry R. Pearl, Senior Vice
President, Treasurer and Chief Financial Officer, R. Gregory Cunningham, Vice
President and General Counsel, and Lyle B. Boarts, Vice President-Human
Resources (the "SF Executive Officers")--will be entitled to receive certain
payments and benefits as a result of the Transaction, if, (i) the SF Executive
Officer is not hired by the KM General Partner and his employment with the SF
General Partner is terminated (including constructive termination) within 24
months from the Closing of the Transaction or (ii) the SF Executive Officer is
hired by the KM General Partner and his employment is subsequently terminated
(including constructive termination) within 24 months from the Closing of the
Transaction. In each case, termination must be for a reason other than for
misconduct and disability. Also, it is expected that Mr. Toole will enter into a
consulting agreement with BNSF following the consummation of the Transaction. As
a result of the Transaction, directors of Santa Fe who are not employees of
Santa Fe or its affiliates will receive lump sum payments representing the
present actuarial value of pension benefits. Santa Fe and BNSF have agreed to
indemnify the Special Committee from certain liabilities related to their
service on the Special Committee. The Executive Officers and Directors of the SF
General Partner collectively own less than 1% of the outstanding Santa Fe Common
Units. For additional detail and discussion regarding the interests of the SF
Executive Officers in the Transaction, see "The Transaction--Interests of
Certain Persons in the Transaction--Officers and Directors of the SF General
Partner."
    
 
   
OFFICERS AND DIRECTORS OF THE KM GENERAL PARTNER
    
 
   
    Under KMEP's Executive Compensation Plan, certain officers of the KM General
Partner--Thomas King, Director and President of the KM General Partner, David
Dehaemers, Vice President and Chief Financial Officer of the KM General Partner,
and Mike Morgan, Vice President of the KM General Partner--have been granted
incentive compensation awards which become 50% vested on January 1, 2000 and
100% vested on January 1, 2002. It is anticipated that the value of such awards
will significantly increase as a result of the Transaction. For additional
detail and discussion regarding the interests of these

officers in the Transaction, see "The Transaction--Interests of Certain Persons
in the Transaction-- Officers and Directors of the KM General Partner."
    
 
   
KM GENERAL PARTNER
    
 
   
    Under the terms of the KMEP Partnership Agreement, the KM General Partner is
entitled to receive a specified percentage of the quarterly cash distributions
to the limited partners of KMEP. The percentage varies depending upon the amount
of the quarterly distribution. See "Description of the KMEP Partnership
Agreement--Cash Distribution Policy." The percentage of Available Cash
distributed to the KM General Partner as an incentive distribution is generally
higher than the corresponding percentage presently distributed to the SF General
Partner. See "Risk Factors--Certain Risks Associated with the
Transaction--Differences in Partnership Agreements May be Adverse to Holders of
Santa Fe Common Units" and "Risk Factors--Risks Associated with KMEP Partnership
Agreement and State Partnership Law--Differences in Cash Distribution Policies."

Partner in the Transaction, see "The Transaction--Interests of Certain Persons

                                  RISK FACTORS
 
    HOLDERS OF KMEP COMMON UNITS AND SANTA FE COMMON UNITS SHOULD CAREFULLY
REVIEW THE INFORMATION SET FORTH BELOW, IN ADDITION TO THE OTHER INFORMATION
CONTAINED IN THIS JOINT PROXY STATEMENT/PROSPECTUS, IN EVALUATING THE
TRANSACTION.
 
CERTAIN RISKS ASSOCIATED WITH THE TRANSACTION
 
   
    FERC PROCEEDINGS; POSSIBLE EFFECT ON RATES.  Various shippers have filed
complaints before the Federal Energy Regulatory Commission ("FERC") challenging
certain of Santa Fe's pipeline tariff rates, alleging that such rates are not
entitled to "grandfathered" status under the Energy Policy Act of 1992 ("EPACT")
due to the development of factors constituting "changed circumstances" within
the meaning of EPACT. See "The Parties--Santa Fe--Legal Proceedings Related to
Santa Fe Operations." Certain of these complaints have alleged that the
Transaction, with its contemplated cost savings from the combination of the
businesses of Santa Fe and KMEP (see "The Transaction--Reasons for the
Transaction; Recommendations of the General Partners"), provides an additional
factor constituting "changed circumstances." Santa Fe has taken the position
that such rates are "grandfathered" and that "changed circumstances" do not
exist. However, these proceedings involve complex rules and regulations and
numerous factual issues, all of which must be considered and analyzed with the
benefit of a limited number of legal precedents. It is possible that the factors
cited by the complaining parties in support of "changed circumstances,"
including consummation of the Transaction and realization of cost savings
contemplated thereby, could, when considered individually or cumulatively, be
found to constitute "changed circumstances." Such a finding could result in very
substantial rate refunds and prospective rate reductions, thereby offsetting or
perhaps exceeding any cost savings that may be realized from the Transaction. A
finding of "changed circumstances" could thus have a material adverse effect on
the SF Operating Partnership's and KMEP's results of operations, financial
condition, liquidity and funds available for distributions to holders of KMEP
Common Units following the Closing. See "The Parties--Santa Fe-- Legal
Proceedings Related to Santa Fe Operations."
    
 
   
    RISKS ASSOCIATED WITH REFINANCING OF KMEP LOAN FACILITY; LEVERAGE.  KMEP has
obtained a commitment letter from Goldman Sachs Credit Partners L.P., as lead
arranger, and First Union Capital Markets Corp., as co-arranger, for the KMEP
Loan Facility. KMEP intends to use the net proceeds from the KMEP Loan Facility
for (i) the refinancing of approximately $133.8 million of existing indebtedness
of OLP-A and OLP-B, including the payment of the make-whole premium on the KMEP
First Mortgage Notes, (ii) OLP-D's acquisition of the general partner interest
in Santa Fe from the SF General Partner for $84.4 million in cash, (iii) the $25
million cash contribution to be made by KMEP to Shell CO(2) Company, (iv) the
payment at par of any VREDs not tendered in the VRED Exchange Offer, (v) the
fees, costs and expenses of the Transaction (estimated to be approximately $13
million) and (vi) general working capital and other general partnership
purposes. Commencing in May 2000, the amount available under the KMEP Loan
Facility reduces on a quarterly basis, with the final installment due in
February 2005. KMEP intends to pay the principal installments due under the KMEP
Loan Facility with cash generated from operations. However, there can be no
assurance that cash generated from operations will be sufficient to make such
payments.
    
 
    EFFECT OF FAILURE TO ACHIEVE BUSINESS STRATEGY.  On February 14, 1997, the
current management of KMEP acquired the KM General Partner. Current management
has sought to reposition KMEP as a growth-oriented limited partnership. See "The
Parties--KMEP--Business Strategy". Between January 1, 1997 and October 17, 1997
(the last trading day before the Transaction was announced), the price of a KMEP
Common Unit increased 182.3%, from $13.813 to $39.00 (adjusted for the 2 for 1
common unit split effective October 1, 1997). Although quarterly cash
distributions increased from $.3150 to $.50 per KMEP Common Unit, the yield on
the KMEP Common Units decreased from 9.12% to 5.13%. In contrast, between
January 1, 1997 and October 17, 1997, the price of a Santa Fe Common Unit
increased 8.2%, from $38.00 to $41.125, its quarterly cash distributions
remained constant at $.75 per unit and its
 
                                       21
<PAGE>
yield decreased from 7.89% to 7.29%. See "Comparative Market Price Data." The
foregoing may indicate that KMEP, to a greater degree than Santa Fe, is
perceived and valued as a growth-oriented partnership likely to generate
increased earnings and distributions. Accordingly, KMEP Common Units may trade
differently than Santa Fe Common Units have and may experience more volatility.
There can be no assurance that KMEP will be able to continue to increase
earnings and cash distributions. The failure to continue to increase earnings
and cash distributions could adversely affect prevailing market prices of the
KMEP Common Units.
 
   
    RISKS ASSOCIATED WITH UNIT HOLDER LITIGATION RELATED TO THE PENDING
TRANSACTION.  Shortly after the announcement of the Transaction, three purported
Santa Fe Common Unit holder class action lawsuits objecting to the Transaction
were filed in Delaware and one was filed in California. The three actions filed
in Delaware have been consolidated into one action. Generally, the actions
allege that certain defendants suffered from a conflict of interest in the
negotiation of the Transaction, that despite this conflict they did not appoint
or retain independent representation for the Santa Fe Common Unit holders, and
that this conflict resulted in an excessive payment to the SF General Partner.
The actions further allege that the defendants breached their duties of loyalty
and due care to the Santa Fe Common Unit holders and that the defendants failed
to fully inform themselves about the value of the Santa Fe Common Units. The
actions seek certification of a class action on behalf of the Santa Fe Common
Unit holders, preliminary and permanent injunctions of the Transaction,
rescission of the Transaction if it is consummated, an award of damages
including attorneys' fees, an accounting by defendants of any special benefits
obtained from the Transaction, imposition of a constructive trust for any
consideration received by the defendants, and any other relief the court finds
appropriate. Although as of this date, plaintiffs have not initiated efforts to
obtain injunctive relief, if they took such action and were successful prior to
the Closing, KMEP and Santa Fe may be prohibited from consummating the
Transaction. Even if plaintiffs are unable to successfully enjoin consummation
of the Transaction, if, following the Closing, they successfully assert their
claims, the Transaction may be subject to rescission or the defendants may be
required to pay damages which may have a materially adverse impact on KMEP.
Defendants believe that all of these lawsuits are without merit and intend to
oppose them vigorously. For more information regarding the specific allegations
made in each action and the names of the actions, see "The Transaction--Certain
Pending Litigation."
    
 
   
    COMBINATION OF PIPELINE OPERATIONS; REALIZATION OF SYNERGIES.  The
management of KMEP believes that KMEP will be able to integrate the
geographically and operationally diverse businesses of KMEP and Santa Fe in a
beneficial and profitable manner. However, the operations and management of KMEP
and Santa Fe are different, and KMEP may incur costs or encounter other
challenges not currently anticipated which may negatively affect its prospects.
In addition, there can be no assurance that KMEP will realize in whole or in
part the anticipated synergies reflected in the pro forma financial statements
or the "Disclosure Regarding Forward Looking Information" or "The
Parties--KMEP--Business Strategy" sections. The integration of operations
following the Transaction will require the dedication of management and other
personnel which may temporarily distract their attention from the day-to-day
business of the combined partnership, the development or acquisition of new
properties and the pursuit of other business acquisition opportunities.
    
 
   
    CHANGES IN MANAGEMENT OF SANTA FE ASSETS.  Following the Transaction, the
assets of Santa Fe previously managed by the SF General Partner will be under
the ultimate control and management of different persons. While many of the
individuals responsible for the day-to-day management of the Santa Fe assets are
expected to continue with KMEP following the Transaction, most members of senior
management of Santa Fe will not remain with KMEP.
    
 
   
    ISSUANCE OF KMEP COMMON UNITS TO HOLDERS OF VREDS MIGHT ADVERSELY AFFECT
MARKET PRICE.  As a result of the Transaction, OLP-D on behalf of SF Holdings,
will pursuant to the VRED Exchange Offer, offer to exchange each $1,000
principal amount of the VREDs for 51.720927 KMEP Common Units. The exchange
offer will close 90 days after the Closing. As a result, the approximately 11.3
million KMEP
    
 
                                       22
<PAGE>
   
Common Units to be received by the SF General Partner upon such exchange would
be distributed to the holders of the VREDs. These KMEP Common Units would equal
approximately 27.8% of the total outstanding KMEP Common Units post-Closing,
unless KMEP elects to pay cash in lieu of delivering KMEP Common Units in
accordance with the terms of the VRED Indenture. See "The Transaction-- VREDs."
A holder of VREDs who has exchanged VREDs pursuant to the VRED Exchange Offer
may determine, for tax and other reasons, not to hold their KMEP Common Units on
a long-term basis. To provide for an orderly distribution of such KMEP Common
Units and to raise additional capital, KMEP intends, subject to market
conditions, to commence an underwritten public offering of newly issued KMEP
Common Units following the expiration of the VRED Exchange Offer. Former VRED
holders may participate in such offering, as selling unitholders subject to such
holders' execution of the appropriate documents required by the managing
underwriter and sharing the fees and expenses of the offering on a pro rata
basis. KMEP can make no predictions as to the effect, if any, that sales of such
KMEP Common Units or the availability of such KMEP Common Units for sale might
have on the market price prevailing from time to time. Nevertheless, sales of
substantial amounts of the KMEP Common Units received in exchange for the VREDs
could adversely affect prevailing market prices of the KMEP Common Units.
    
 
   
    DIFFERENCES IN PARTNERSHIP AGREEMENTS MAY BE ADVERSE TO HOLDERS OF SANTA FE
COMMON UNITS.  If the Transaction is consummated, all holders of Santa Fe Common
Units will become holders of KMEP Common Units immediately following the
liquidation of Santa Fe. The rights and obligations of, and matters affecting,
the holders of KMEP Common Units and Santa Fe Common Units under their
respective partnership agreements--the Second Amended and Restated Agreement of
Limited Partnership of KMEP dated effective as of January 14, 1998 (the "KMEP
Partnership Agreement") and the Santa Fe partnership agreement--are similar in
many respects. (For a description of the KMEP Partnership Agreement, see
"Description of KMEP Partnership Agreement" and "Material Federal Income Tax
Considerations.") However, certain material differences exist between the
respective partnership agreements, which differences may have an adverse impact
on holders of Santa Fe Common Units. The percentage of Available Cash
distributed to the KM General Partner as an incentive distribution is generally
higher than the percentage distributed to the SF General Partner as an incentive
distribution. As a result, under the KMEP Partnership Agreement, the KM General
Partner will receive 50% of any incremental quarterly cash distributions after
the holders of KMEP Common Units have received cash quarterly distributions of
$.4675 per KMEP Common Unit, whereas under the Santa Fe Partnership Agreement,
the SF General Partner is only entitled to receive 30% of any incremental
quarterly cash distributions after the holders of the Santa Fe Common Units have
received quarterly cash distributions equal to $.70 per Santa Fe Common Unit (or
$.504 per common unit on a KMEP equivalent basis (I.E., $.70 divided by the 1.39
KMEP Common Units to be issued for each Santa Fe Common Unit)). In addition, (i)
the KMEP Partnership Agreement has an anti-takeover provision eliminating the
right of any holder or group of holders (excluding the KM General Partner or its
affiliates) who owns 20% or more of the KMEP Common Units to vote; (ii) the KM
General Partner has pre-emptive rights with respect to future issuances of KMEP
Common Units, which the SF General Partner does not have, and (iii) actions
which require KMEP Common Unit holder approval generally only require the
affirmative vote of the holders of a majority of the KMEP Common Units, whereas,
similar actions requiring Santa Fe Common Unit holder approval generally require
the affirmative vote of the holders of at least 66 2/3% of the Santa Fe Common
Units. See "--Risks Associated with KMEP Partnership Agreement and State
Partnership Law--Effects of Anti-takeover Provisions," "--Risks Associated with
KMEP Partnership Agreement and State Partnership Law--Pre-emptive Rights of
General Partner," "The Transaction--Interests of Certain Persons in the
Transaction--KM General Partner," "Comparison of Common Unit Holders' Rights"
and "Material Federal Income Tax Considerations."
    
 
    FIXED EXCHANGE RATIO.  Under the terms of the Purchase Agreement, each Santa
Fe Common Unit will represent the right to receive 1.39 KMEP Common Units. The
Purchase Agreement does not contain any provision for adjustment of the Exchange
Ratio based solely on fluctuations in the market prices of Santa Fe Common Units
or KMEP Common Units. There can be no assurance that one or both of such
 
                                       23
<PAGE>
   
market prices at closing will not be lower than the market prices on the date of
the execution of the Purchase Agreement or the current market prices. The
Purchase Agreement does provide for mutual termination rights if the 20-trading
day average price of KMEP Common Units is ever less than $31.32 or greater than
$46.98 prior to the Closing.
    
 
   
RISKS ASSOCIATED WITH LEGAL PROCEEDINGS RELATED TO SANTA FE OPERATIONS
    
 
   
    Santa Fe is currently a party to several legal proceedings, including,
without limitation: (i) three proceedings before the FERC, which generally
challenge certain of Santa Fe's existing tariff rates, (ii) a proceeding before
the CPUC, which generally challenges rates charged by Santa Fe for intrastate
transportation of refined petroleum products through its pipeline system in the
State of California and requests prospective rate adjustments, (iii) a judicial
reference proceeding between Santa Fe and Southern Pacific Transportation
Company ("SPTC") to determine the extent, if any, to which the rent payable by
Santa Fe for the use of pipeline easements on rights-of-way held by SPTC should
be adjusted pursuant to existing contractual arrangements and (iv) environmental
proceedings related to ground water and soil contamination in Elmira,
California. In addition, Santa Fe has liabilities under settlements related to
ground water and soil contamination in the vicinity of Santa Fe's storage
facilities and truck loading terminal at Sparks, Nevada and 18 other sites.
    
 
   
    The initial decision rendered by the presiding Administrative Law Judge in
one of the pending FERC proceedings, if implemented in its current form and also
applied to the Sepulveda lines rate at issue in Docket No. IS98-1-000, could
reduce prospective revenues by approximately $8 million to $10 million annually
and require Santa Fe to pay reparations through year end 1997 in the approximate
amount of $30 million. Reparations and interest will continue to accrue at
approximately $8 million per annum until new prospective rates become effective.
The complaints before the CPUC seek prospective rate reductions aggregating
approximately $15 million per year.
    
 
   
    KMEP and Santa Fe are not able to predict with certainty the final outcome
of these legal proceedings. However, the ultimate resolution of these
proceedings could have a material adverse effect on KMEP's results of
operations, financial condition, liquidity and ability to maintain its announced
annual cash distribution of $2.25 per KMEP Common Unit. See "The Parties-- Santa
Fe--Legal Proceedings Related to Santa Fe Operations" and the annual and
quarterly reports of Santa Fe, filed with the Commission, which are incorporated
herein by reference, for a more detailed description of these proceedings.
    
 
NO ASSURANCE THAT TARIFF RATES CAN BE MAINTAINED OR INCREASED
 
   
    Revenues from interstate and California intrastate common carrier
transportation on the Liquids Pipelines are determined in accordance with
tariffs filed with FERC and the CPUC, respectively. As discussed above, Santa
Fe's pipeline tariffs are subject to challenge before the FERC and CPUC. Such
challenges pose a threat to the rates of Santa Fe regardless of whether the
Transaction is consummated, and thus could, if successful, result in rate
refunds and/or lower prospective pipeline rates, which could have a material
adverse effect on Santa Fe's results of operations, financial condition,
liquidity and funds available for distributions to holders of Santa Fe Common
Units even in the absence of the Transaction.
    
 
   
    Santa Fe's rates could also be adversely affected in the future by increased
competition.
    
 
POSSIBLE INSUFFICIENCY OF CASH FLOW TO PAY ANNOUNCED DISTRIBUTIONS
 
   
    The pro forma historical combined cash flow of KMEP and Santa Fe would not
be sufficient to pay KMEP's announced annual distribution of $2.25 per KMEP
Common Unit. The ability of KMEP to generate sufficient cash flow to pay such
distribution will depend on the ability of KMEP to realize anticipated cost
savings resulting from the Transaction and to increase revenues in certain
sectors in accordance with KMEP's 1998 business plan. Although KMEP's management
believes that such cost savings and revenue increases can be realized, there can
be no assurance in this regard. In the short term
    
 
                                       24
<PAGE>
KMEP may fund distributions from borrowings, to the extent available, but
ultimately the ability of KMEP to sustain announced distributions will depend on
the ability of KMEP to increase distributable cash flow. In addition, there is
no guaranteed minimum quarterly distribution under the KMEP Partnership
Agreement.
 
CASH DISTRIBUTIONS WILL FLUCTUATE WITH PERFORMANCE; NO MINIMUM DISTRIBUTION
 
    GENERAL.  Although the KM General Partner will distribute 100% of KMEP's
Available Cash (as defined herein), there can be no assurance regarding the
amounts of Available Cash to be generated by KMEP. KMEP's profitability and its
ability to make distributions to holders of KMEP Common Units will depend to a
large extent upon volumes of NGLs and refined petroleum products that the
Liquids Pipelines transport and to a lesser extent upon the volume of coal
transloaded and stored by the Coal Terminals and volumes of NGLs for
fractionation. Diminished volumes would decrease KMEP's profits and,
consequently, the amount of cash available for distribution to holders of KMEP
Common Units. Because the demand for such products is subject to numerous
factors outside KMEP's control, no assurance can be given regarding future
volumes.
 
   
    FACTORS AFFECTING TRANSPORTATION VOLUMES.  Transportation volumes for NGLs
and refined petroleum products are affected primarily by the market demand for
products in the geographic regions served by the Liquids Pipelines. Volumes for
the Coal Terminals depend on the market demand for western and Illinois coal,
economic and available rail transportation from sources of supply and economic
barge transportation to delivery points. Market demand for NGLs, refined
petroleum products and coal may be affected by future economic conditions,
weather, fuel conservation measures, alternate fuel requirements, governmental
and environmental regulation, demographic changes or technological advances in
fuel economy and energy generation devices. KMEP cannot predict the effect of
such factors on the demand for the transportation of NGLs and refined petroleum
products in the Liquids Pipelines and the handling and storage of coal. See "The
Parties--Santa Fe--Markets" and "--Principal Customers."
    
 
   
    PROFITABILITY IS DEPENDENT ON CERTAIN MAJOR CUSTOMERS.  Major end-users of
NGLs and refined petroleum products transported by the Liquids Pipelines include
wholesalers and retailers of refined petroleum products in the relevant service
areas, refinery facilities in the Chicago area, a world-scale petrochemical
plant near Lake Charles, Louisiana and United States military bases. Major
suppliers of refined petroleum products transported on the Liquids Pipelines
include refineries located in Los Angeles, San Francisco and Bakersfield,
California, Chicago, Illinois, Houston and El Paso, Texas and Seattle,
Washington. A disruption of operations at any of such facilities could adversely
affect KMEP's revenues by reducing the volumes of NGLs and refined petroleum
products transported through the Liquids Pipelines. See "The Parties-- Santa
Fe--Markets" and "--Principal Customers." In addition, four major customers ship
approximately 80% of all coal loaded through the Coal Terminals. KMEP has
business interruption insurance to protect itself against losses from reduced
volumes of products transported as a result of disrupted operations of KMEP's
assets or of a supplier or end-user because of physical loss or damage and
intends to obtain similar insurance with respect to Santa Fe's operations.
However, there can be no assurance that business interruption insurance will be
adequate to cover losses that might result from disruptions of operations.
Should KMEP lose any of its major customers, KMEP's profitability could be
adversely affected along with its ability to make distributions to holders of
KMEP Common Units.
    
 
    ESTABLISHMENT OF RESERVES MAY AFFECT DISTRIBUTIONS.  The KMEP Partnership
Agreement gives the KM General Partner broad latitude in establishing reserves
that affect the amount of Available Cash because the KM General Partner may in
its reasonable discretion determine amounts that can be set aside as reserves
for the proper conduct of the business.
 
                                       25
<PAGE>
RISKS ASSOCIATED WITH LEVERAGE
 
   
    IMPACT ON ABILITY TO MAKE CASH DISTRIBUTIONS.  As of September 30, 1997,
KMEP and Santa Fe had approximately $130.9 million and $355.0 million of
indebtedness, respectively. After giving effect to the Transaction, the
incurrence of the maximum available debt under the KMEP Loan Facility and the
refinancing of the Refinanced Indebtedness, and assuming the exchange of all of
the VREDs for KMEP Common Units, KMEP is anticipated to have approximately $617
million of indebtedness. In addition, the debt service obligations associated
with such indebtedness may reduce the Available Cash for distribution by KMEP to
holders of KMEP Common Units and to the KM General Partner. The ability of KMEP
to meet these debt service obligations will depend primarily upon its future
performance, which will be subject to prevailing economic conditions and to
financial, business and other factors (including regulation), many of which are
beyond its control. KMEP may in the future incur additional indebtedness in
order to finance acquisitions or for general business purposes.
    
 
   
    ASSETS PLEDGED TO SECURE DEBT.  The KMEP Loan Facility initially will be
secured by a first priority lien on (i) KMEP's limited partner interests in the
KMEP Partnerships; (ii) all of the assets of OLP-D (including its general
partner interest in the SF Operating Partnership), (iii) KMEP's ownership
interests in the fractionator and Shell CO(2) Company and (iv) intercompany
notes to be executed by the KMEP Partnerships in favor of KMEP for loan proceeds
lent to them by KMEP. If KMEP fails to maintain certain financial ratios, then
each of the KMEP Operating Partnerships will be obligated to secure its
intercompany note with its assets. Santa Fe has also granted liens on
substantially all of its properties to secure its existing indebtedness and such
liens will remain in effect after consummation of the Transaction. If an event
of default occurs, the lenders will have the right to foreclose upon such
collateral. Foreclosure, in addition to causing an investment loss, could have
significant adverse tax consequences for holders of KMEP Common Units, including
the realization of taxable income by such holders without a corresponding
distribution of cash. Similarly, holders of KMEP Common Units could have
increased taxable income without a corresponding increased cash distribution if,
while there is substantial indebtedness outstanding, KMEP were to dispose of
assets.
    
 
   
    INSTRUMENTS GOVERNING INDEBTEDNESS CONTAIN RESTRICTIVE COVENANTS.  KMEP may
be prevented by the instruments governing its indebtedness (including the KMEP
Loan Facility) from engaging in certain transactions which might otherwise be
considered beneficial to KMEP, and such provisions may limit or prohibit
distributions to holders of KMEP Common Units under certain circumstances. The
agreements governing such indebtedness generally require KMEP's operating
partnerships to comply with various affirmative and negative covenants,
including without limitation, the maintenance of certain financial ratios and
restrictions on (i) the incurrence of additional indebtedness; (ii) entering
into mergers, consolidations and sales of assets; (iii) making investments; and
(iv) granting liens. In addition, the agreements governing KMEP's indebtedness
generally prohibit KMEP from making cash distributions to holders of KMEP Common
Units more frequently than quarterly, from distributing amounts in excess of
100% of Available Cash for the immediately preceding calendar quarter and from
making any distribution to holders of KMEP Common Units if an event of default
exists or would exist upon making such distribution. The instruments governing
the SF Operating Partnership's indebtedness contain similar restrictions,
including the maintenance of certain cash levels. The instruments governing any
additional indebtedness incurred to refinance the indebtedness may also contain
similar restrictions.
    
 
   
    KMEP's $110 million First Mortgage Notes due June 30, 2007 ("KMEP First
Mortgage Notes") permit KMEP to prepay such indebtedness only upon payment of a
make-whole premium. KMEP intends to refinance the KMEP First Mortgage Notes (and
pay the make-whole premium) with the proceeds from the KMEP Loan Facility.
    
 
    The SF Operating Partnership's First Mortgage Notes, with an outstanding
principal amount of $305 million as of September 30, 1997 (the "Santa Fe First
Mortgage Notes"), generally may not be prepaid at any time prior to December 15,
1999. After December 15, 1999 and prior to December 15, 2002,
 
                                       26
<PAGE>
Santa Fe may prepay the Santa Fe First Mortgage Notes with a make-whole
prepayment premium. On or after December 15, 2002 and prior to December 15,
2003, Santa Fe may prepay the Santa Fe First Mortgage Notes with a prepayment
premium equal to .7133% of the principal amount so prepaid. After December 15,
2003, Santa Fe may prepay the Santa Fe First Mortgage Notes in whole or in part
without a prepayment premium. Pursuant to the Purchase Agreement, after the
Closing, the SF Operating Partnership is restricted from taking certain actions
with respect to $190 million of the Santa Fe First Mortgage Notes, including the
prepayment of such amount. Such restrictions may limit KMEP's flexibility in
structuring or refinancing existing or future indebtedness. See "The
Transaction--Santa Fe First Mortgage Notes."
 
RISKS ASSOCIATED WITH PIPELINE EASEMENTS
 
   
    A significant portion of the SF Pipeline System is located on railroad
right-of-ways as to which the SF Operating Partnership or Santa Fe was granted
easements by SPTC for the construction and operation of the SF Pipeline System.
SPTC, or its predecessors in interest, acquired some of such right-of-way
pursuant to federal statutes enacted in 1871 and 1875. The right-of-way granted
under the 1871 statute was thought to be an outright ownership interest, which
would continue in perpetuity unless the right-of-way ceased to be used for
railroad purposes, in which case the ownership interest would be extinguished.
SPTC and its predecessors in interest have used the right-of-way for railroad
purposes since the railroad was constructed. Except for one lawsuit which was
dismissed, the SF Pipeline System has operated without challenge to the validity
of the easements granted by Southern Pacific on and beneath the land since
construction of the SF Pipeline System in the 1950s.
    
 
    Two United States Circuit Courts, however, have determined, in decisions
rendered in 1979 and 1980, that railroad right-of-ways granted under laws
similar to the 1871 statute provide only a surface easement for railroad
purposes without any right to the subsurface. If a court were to determine that
the 1871 statute also prohibits the use of the subsurface by the railroad or its
assignees for the operation of a pipeline, the SF Operating Partnership may be
required to obtain easements from subsurface landowners in order to continue to
maintain the SF Pipeline System beneath the right-of-way SPTC was granted under
the 1871 statute. The SF General Partner and the KM General Partner believe that
such easements could be obtained over time at a cost that would not have a
material adverse effect on the SF Operating Partnership, although no assurance
in this regard can be given.
 
    KMEP and Santa Fe have each been advised by counsel that it has the power of
eminent domain in the states in which it operates (except for Illinois) with
respect to the Liquids Pipelines (other than the Central Basin Pipeline),
assuming it meets certain requirements that differ from state to state. While
there can be no assurance, KMEP believes that it meets such requirements. KMEP
does not believe that it has the power of eminent domain with respect to the
Central Basin Pipeline. The inability of KMEP to exercise the power of eminent
domain could have a material adverse effect on the business of KMEP in those
instances where KMEP will not have the right through leases, easements,
rights-of-way, permits or licenses to use or occupy the property used for the
operation of the Liquids Pipelines and where KMEP is unable to obtain such
rights.
 
RISKS ASSOCIATED WITH SHELL CO(2) COMPANY
 
    The letter of intent regarding the formation of Shell CO(2) Company provides
that KMEP will be entitled to a fixed, guaranteed quarterly distribution of
approximately $3.6 million ($14.5 million per year) during the four year period
ended December 31, 2001. In 2002 and 2003, KMEP's cash distributions will be
increased or decreased so that the aggregate cash distributions received by KMEP
during the first six years of Shell CO(2) Company's existence will be equal to
KMEP's partnership interest percentage of the cumulative cash distributions of
Shell CO(2) Company during such period (which initially is expected to equal
20%) on a present value basis (discounted at 10%). Under certain scenarios,
which management believes are unlikely, it is possible that KMEP would not
receive any distributions from Shell CO(2) Company during 2002 and 2003 and
could be required to return a portion of the distributions received
 
                                       27
<PAGE>
during the first four years. After 2003, KMEP will participate in distributions
in accordance with its partnership percentage.
 
COSTS OF ENVIRONMENTAL REGULATION
 
    The business and operations of KMEP and Santa Fe are subject to federal,
state and local laws and regulations relating to environmental practices. In
particular, KMEP and Santa Fe could incur significant costs and liabilities in
the event of an accidental leak or spill in connection with liquid petroleum
products transportation and storage. The costs and liabilities associated with
leaks and spills of hazardous materials, either individually or in the
aggregate, could negatively affect the level of cash available for distribution
to holders of KMEP Common Units. Moreover, it is possible that other
developments, such as increasingly strict environmental laws and regulations,
could result in increased costs and liabilities to KMEP and Santa Fe. KMEP and
Santa Fe cannot predict the ultimate impact on their business and operations of
the EPA standards or the impact of future environmental measures. The costs of
environmental regulation are, however, already significant and there is a
possibility that additional regulation could negatively affect the level of cash
available for distribution to holders of KMEP Common Units.
 
COMPETITION
 
    Propane competes with electricity, fuel oil and natural gas in the
residential and commercial heating market. In the engine fuel market, propane
competes with gasoline and diesel fuel. Butanes and natural gasoline used in
motor gasoline blending and isobutane used in alkylation compete with
alternative products. NGLs used as feedstocks for refineries and petrochemical
plants compete with alternative feedstocks. As a result, NGL demand is
significantly affected by the availability and prices of alternative energy
sources and feedstocks. Such competition could ultimately result in lower levels
of KMEP profits and lower cash distributions to holders of KMEP Common Units.
 
    The KMEP and Santa Fe operating partnerships conduct their operations
without the benefit of exclusive franchises from government entities. In
addition, they provide common carrier transportation services through the
Liquids Pipelines at posted tariffs, and, in virtually all cases, without
long-term contracts for transportation service with its customers. Demand for
transportation services for refined petroleum products is primarily a function
of total and per capita fuel consumption, prevailing economic and demographic
conditions, alternate modes of transportation, alternate product sources and
price.
 
    Because pipelines are generally the lowest cost method for intermediate and
long-haul overland product movement, the Liquids Pipelines' most significant
competitors are proprietary pipelines owned and operated by major oil companies
in the areas where the Liquids Pipelines deliver products, refineries within the
operating partnerships' market areas served by the Liquids Pipelines and trucks.
The possibility exists that additional pipelines may in the future be
constructed to serve specific markets served by the Liquids Pipelines. Trucks
competitively deliver products in certain markets. Recently, the SF Pipeline
System has experienced minor but notable reductions in product volumes delivered
to certain shorter-haul destinations, primarily Orange and Colton, California,
due to increased utilization of trucking by major oil companies. Management
cannot predict with certainty whether this trend towards increased short-haul
trucking will continue in the future.
 
    Utilization of and demand for terminaling services varies widely throughout
the Liquids Pipelines. Certain of the major petroleum companies as well as
independent terminal operators are presently in direct competition with Santa Fe
and KMEP at several terminal locations. At those locations, market share is
primarily a function of pricing, service capabilities and available tankage.

TAX RISKS
 
    For a general discussion of the expected federal income tax consequences of
the Transaction and of acquiring, owning and disposing of KMEP Common Units, see
"Material Federal Income Tax Considerations." All references to "Sections" in
this Tax Risks discussion and in the "Material Federal Income Tax
Considerations" discussion are to sections of the Code.
 
   
    TAX TREATMENT OF TRANSACTION DEPENDENT ON PARTNERSHIP STATUS.  The tax
treatment of the Transaction is dependent upon both KMEP and Santa Fe being
treated as partnerships for federal income tax purposes. If either were treated
as a corporation, the Transaction would be treated as a taxable exchange. If,
for federal income tax purposes, KMEP is treated as a corporation and Santa Fe
is treated as a partnership, the Transaction will be taxable to Santa Fe and the
holders of Santa Fe Common Units with the resulting gain increasing the basis of
the Santa Fe Common Units and, in turn, the basis of the KMEP Common Units
received by such holders. If, for federal income tax purposes, Santa Fe is
treated as a corporation, the Transaction will be taxable to Santa Fe and the
liquidation of Santa Fe will result in the receipt by Santa Fe Common Unit
holders of KMEP Common Units in a taxable exchange. As a consequence, Santa Fe
and the Santa Fe Common Unit holders would have material federal income tax
liabilities, which would exceed cash distributions from Santa Fe and KMEP. See
"Material Federal Income Tax Considerations--Tax Consequences of the
Transaction." Morrison & Hecker and Mayer, Brown & Platt will render their
opinions that KMEP and Santa Fe, respectively, are classified as partnerships
for federal income tax purposes. See "Material Federal Income Tax
Considerations--General Features of Partnership Taxation-- Partnership Status."
The opinions of counsel represent only counsels' respective legal judgments as
to particular issues and are not binding on the IRS or the courts. No ruling
will be requested from the IRS with respect to the Transaction or the
classification of KMEP or Santa Fe. Thus, no assurance can be provided that such
opinions set forth herein would be sustained by a court if contested by the IRS.
    
 
   
    NO AMORTIZATION OF BOOK-UP ATTRIBUTABLE TO INTANGIBLES.  The Transaction
will result in a restatement of the capital accounts of both the former Santa Fe
Common Unit holders and the pre-Transaction KMEP Common Unit holders to fair
market value ("Book-Up") and an allocation of such increased capital account
value among KMEP's assets will be based on the values indicated by an
independent appraisal obtained by the KM General Partner. The KM General Partner
has obtained an independent appraisal which indicates that all, or substantially
all, of such value is attributable to tangible assets. However, if such
valuations were challenged by the IRS and such challenge was successful, a
portion of this Book-Up could be allocated to intangible assets that will not be
amortizable either for tax or capital account purposes, and therefore, will not
support a Curative Allocation (as later defined) of income. This could result in
a disproportionate allocation of taxable income to either a pre-Transaction KMEP
Common Unit holder or a former Santa Fe Common Unit holder. See "Material
Federal Income Tax Considerations--Tax Consequences of Holding KMEP
Units--Capital Accounts, Valuation of Assets and Curative Allocations under
Section 704(c)" and "Material Federal Income Tax Considerations--Tax
Consequences of Holding KMEP Units--Fungibility Issues Arising From
Intangibles."
    
 
    CASH FOR FRACTIONAL UNIT PAYMENTS.  The KM General Partner intends to take
the position that Fractional Unit Payments are distributions that are nontaxable
to the Santa Fe Common Unit holders to the extent of their basis. It is possible
that the IRS may seek to ignore the form of the Transaction and take the
position that the receipt of the Fractional Unit Payments should be treated
under the "Disguised Sale Rules" as a payment to Santa Fe in exchange for a
portion of the limited partner interests in the SF Operating Partnership
resulting in gain recognition to Santa Fe and the holders of Santa Fe Common
Units. See "Material Federal Income Tax Considerations--Tax Consequences of the
Transaction--Disguised Sale Rules."
 
   
    CONSTRUCTIVE TERMINATIONS; IMPACT ON TAXABLE INCOME AND DEPRECIATION.  The
distribution of KMEP Common Units offered hereby, in addition to other sales of
KMEP Common Units due to its trading activity in a twelve-month period, will
likely result in a constructive termination of KMEP for federal
    
 
                                       29
<PAGE>
   
income tax purposes upon the closing of the Transaction. In addition, the
Transaction will result in a constructive termination of the SF Operating
Partnership. These constructive terminations will result in a deferral of an
allocable share of depreciation deductions and a corresponding acceleration of
taxable income allocable to each pre-Transaction KMEP Common Unit holder and any
former Santa Fe Common Unit holder. The KM General Partner estimates that the
effect of such constructive terminations and depreciation conventions will be a
reduction in 1998 of approximately 50% in the depreciation deductions and net
Curative Allocations available to former Santa Fe Common Unit holders and
pre-Transaction KMEP Common Unit holders. The KM General Partner estimates that
there will be no material adverse effect on depreciation deductions and net
Curative Allocations for 1999 and 2000 resulting from the constructive
terminations. This reduction in depreciation deductions and net Curative
Allocations will increase the federal taxable income, and therefore could
increase the federal income tax liability, of pre-Transaction holders of Santa
Fe Common Units and KMEP Common Units, when compared to such income absent the
Transaction. See "Material Federal Income Tax Considerations--Tax Consequences
of KMEP Common Unit Ownership--Factors Affecting Taxable Income," and "Material
Federal Income Tax Considerations--Disposition of KMEP Common
Units--Constructive Termination."
    
 
    TAX TREATMENT OF KMEP.  The availability to a holder of KMEP Common Units of
the federal income tax benefits of an investment in KMEP depends, in large part,
on the classification of KMEP as a partnership for federal income tax purposes.
Based on certain representations by the KM General Partner and the SF General
Partner and in partial reliance on the opinion of Mayer, Brown & Platt with
respect to the classification of Santa Fe, Morrison & Hecker is of the opinion
that, under current law, KMEP is and will continue to be classified as a
partnership for federal income tax purposes. However, as stated below, no ruling
from the IRS as to such status has been or will be requested, and the opinion of
counsel is not binding on the IRS.
 
    If KMEP were to fail to meet the 90% "qualified income" test (the "National
Resources Exception") for any year prior to or subsequent to the Transaction,
KMEP would be treated as a corporation unless it met the inadvertent failure
exception. See "Material Federal Income Tax Considerations--General Features of
Partnership Taxation--Partnership Status."
 
    If KMEP were classified as an association taxable as a corporation for
federal income tax purposes, KMEP would be required to pay tax on its income at
corporate rates, distributions would generally be taxed to the holders of KMEP
Common Units as corporate distributions, and no income, gain, loss, deduction or
credit would flow through to the holders of KMEP Common Units. Because tax would
be imposed upon KMEP as an entity, the cash available for distribution to the
holders of KMEP Common Units would be substantially reduced. Treatment of KMEP
as an association taxable as a corporation or otherwise as a taxable entity
would result in a material reduction in the anticipated cash flow and after-tax
return to the holders of KMEP Common Units. See "Material Federal Income Tax
Considerations-- General Features of Partnership Taxation--Partnership Status."
 
    There can be no assurance that the law will not be changed so as to cause
KMEP to be treated as an association taxable as a corporation for federal income
tax purposes or otherwise to be subject to entity-level taxation. The KMEP
Partnership Agreement provides that, if a law is enacted that subjects KMEP to
taxation as a corporation or otherwise subjects KMEP to entity-level taxation
for federal income tax purposes, certain provisions of the KMEP Partnership
Agreement relating to the KM General Partner's incentive distributions will be
subject to change, including a decrease in the amount of the Target Distribution
levels to reflect the impact of entity level taxation on KMEP. See "Description
of KMEP Partnership Agreement--Cash Distribution Policy."
 
   
    NO IRS RULING WITH RESPECT TO THE TRANSACTION OR TAX CONSIDERATIONS.  No
ruling has been or will be requested from the IRS with respect to the
Transaction, the classification of KMEP or Santa Fe as a partnership for federal
income tax purposes or any other matter affecting KMEP or Santa Fe. Moreover,
the IRS has announced that it will not grant rulings regarding the federal
income tax treatment of transfers
    
 
                                       30
<PAGE>
   
of assets to certain classes of partnerships in which KMEP would be included.
Accordingly, the IRS may adopt positions that differ from counsels' conclusions
expressed herein. It may be necessary to resort to administrative or court
proceedings in an effort to sustain some or all of counsel's conclusions, and
some or all of such conclusions ultimately may not be sustained. The costs of
any contest with the IRS will be borne directly or indirectly by some or all of
the holders of KMEP Common Units and the KM General Partner.
    
 
   
    ALLOCATION OF PROFIT AND LOSS.  The KMEP Partnership Agreement contains
certain allocations of profits and losses the validity of which under current
law are uncertain and with respect to which counsel is unable to opine. A
successful challenge by the IRS of the validity of such allocations could result
in a material increase in the amount of taxable income allocated to the holders
of KMEP Common Units. See "Material Federal Income Tax Considerations--Tax
Consequences of KMEP Common Unit Ownership-- Ratio of Taxable Income to
Distributions" and "Material Federal Income Tax Considerations--Allocation of
KMEP Income, Gain, Loss and Deduction."
    
 
   
    DEDUCTIBILITY OF LOSSES.  Under the passive loss limitations, losses
generated by KMEP, if any, will only be available to offset future income
generated by KMEP and cannot be used to offset income from other activities,
including passive activities or investments. Unused losses may be deducted when
the holder of KMEP Common Units disposes of all of such holder's KMEP Common
Units in a fully taxable transaction with an unrelated party. It is uncertain
whether any unused passive activity losses previously realized by a Santa Fe
Common Unit holder can be used to offset such Unit holder's allocable share of
KMEP income. Net passive income from KMEP may be offset by a KMEP Common Unit
holder's unused KMEP losses carried over from prior years, but not by losses
from other passive activities, including losses from other publicly traded
partnerships. See "Material Federal Income Tax Considerations--Tax Consequences
of KMEP Common Unit Ownership--Limitations on Deductibility of KMEP Losses."
    
 
    SECTION 754 ELECTION.  Each of KMEP, the KMEP Operating Partnerships and the
SF Operating Partnership has made, will make, as necessary, and maintain the
election provided for by Section 754 of the Code, which will generally permit a
holder of KMEP Common Units to calculate cost recovery and depreciation
deductions by reference to the portion of the Common Unit holder's purchase
price attributable to each asset of KMEP. A constructive termination of KMEP
could result in penalties and a loss of basis adjustments under Section 754, if
KMEP were unable to determine that a termination had occurred and, therefore,
did not make a Section 754 election for the new KMEP. See "Material Federal
Increase Tax Considerations--Tax Treatment of Operations--Section 754 Election."
 
    CONVENTIONS RELATED TO SECTION 743(B) ADJUSTMENTS.  The KM General Partner
intends to depreciate the portion of a Section 743(b) adjustment attributable to
unrealized appreciation in the value of KMEP's property (to the extent of any
unamortized Book-Tax Disparity) using a rate of depreciation derived from the
depreciation method and useful life applied to the common inside tax basis of
such property. It is possible that the IRS could challenge such treatment and,
if successful, the taxable income of either holders of Santa Fe Common Units or
KMEP Common Units could be increased. See "Material Federal Income Tax
Considerations--Tax Consequences of Holding KMEP Units--Capital Accounts,
Valuation of Assets and Curative Allocations under Section 704(c)" and "Material
Federal Income Tax Considerations--Tax Consequences of Holding KMEP
Units--Fungibility Issues Arising From Intangibles."
 
   
    UNIFORMITY OF KMEP COMMON UNITS AND NONCONFORMING DEPRECIATION
CONVENTIONS.  Since KMEP cannot trace the chain of ownership of any particular
KMEP Common Unit, it is unable to track the economic and tax characteristics
related to particular KMEP Common Units from owner to owner. Consequently,
uniformity of the economic and tax characteristics of the KMEP Common Units to
purchasers of such KMEP Common Units must be maintained. To maintain uniformity,
KMEP will adopt certain depreciation conventions that do not conform with all
aspects of certain proposed and final Treasury Regulations. The IRS may
challenge such conventions and, if such a challenge were sustained, the
uniformity of KMEP Common Units may be affected. Non-uniformity could adversely
affect the amount
    
 
                                       31
<PAGE>
of tax depreciation available to a purchaser of KMEP Common Units and could have
a negative impact on the value of the KMEP Common Units. See "Material Federal
Income Tax Considerations--Uniformity of KMEP Common Units," "Material Federal
Income Tax Considerations--Tax Treatment of Operations-- Section 754 Election"
and "Material Federal Income Tax Considerations--Disposition of KMEP Common
Units--Constructive Termination."
 
    TAX LIABILITY EXCEEDING CASH DISTRIBUTIONS OR PROCEEDS FROM DISPOSITIONS OF
KMEP COMMON UNITS.  A holder of KMEP Common Units will be required to pay
federal income tax and, in certain cases, state and local income taxes on such
holder's allocable share of KMEP's income, whether or not such holder receives
cash distributions from KMEP. No assurance is given that holders of KMEP Common
Units will receive cash distributions equal to their allocable share of taxable
income from KMEP. Further, a holder of KMEP Common Units may incur tax liability
in excess of the amount of cash received. See "Material Federal Income Tax
Considerations--Other Taxes" for a discussion of certain other state and local
tax considerations that may be relevant to prospective holders of KMEP Common
Units.
 
    TAX SHELTER REGISTRATION; POTENTIAL IRS AUDIT.  KMEP is registered with the
IRS as a "tax shelter." No assurance can be given that KMEP will not be audited
by the IRS or that tax adjustments will not be made. The rights of a KMEP Common
Unit holder owning less than a 1% profits interest in KMEP to participate in the
income tax audit process have been substantially reduced. Further, any
adjustments in KMEP's returns will lead to adjustments in the returns of holders
of KMEP Common Units and may lead to audits of the holders of KMEP Common Units'
returns and adjustments of items unrelated to KMEP. Each holder of KMEP Common
Units would bear the cost of any expenses incurred in connection with an
examination of the personal tax return of such holder.
 
RISKS ASSOCIATED WITH KMEP PARTNERSHIP AGREEMENT AND STATE PARTNERSHIP LAW
 
   
    DIFFERENCES IN CASH DISTRIBUTION POLICIES.  Under the terms of the KMEP
Partnership Agreement, the KM General Partner is entitled to receive a specified
percentage of the quarterly cash distributions to the partners of KMEP. The
percentage varies depending upon the amount of the quarterly distribution. See
"Description of the KMEP Partnership Agreement--Cash Distribution Policy." After
the holders of KMEP Common Units have received quarterly cash distributions of
$.4675 per KMEP Common Unit, the KM General Partner is entitled to receive 50%
(the highest marginal rate under the KMEP Partnership Agreement) of any
additional cash distributed to the KMEP partners during such quarter. Under the
Santa Fe Partnership Agreement, the SF General Partner is only entitled to
receive 30% (the highest marginal rate under the Santa Fe Partnership Agreement)
of any additional cash distributed to Santa Fe partners during a quarter after
the holders of the Santa Fe Common Units have received quarterly cash
distributions equal to $.70 per Santa Fe Common Unit (or $.504 per unit on a
KMEP equivalent basis (I.E., $.70 divided by the 1.39 KMEP Common Units to be
issued for each Santa Fe Common Unit)). Based on KMEP's current annual
distribution of $2.00 per KMEP Common Unit, the KM General Partner would receive
approximately 14.5% of all such cash distributions and 50% of any distributions
in excess of such amount. Based on KMEP's announced annual distribution of $2.25
per KMEP Common Unit, the KM General Partner would receive approximately 20.8%
of all such cash distributions and 50% of any distributions in excess of such
amount. If the distribution percentages in the Santa Fe Partnership Agreement
rather than the KMEP Partnership Agreement were used with an equivalent annual
distribution of $3.1275 per unit ($2.25 multiplied by the Exchange Ratio), the
KM General Partner would receive approximately 7.7% of such cash distributions
and 30% of any distributions in excess of such amount.
    
 
    LIMITED VOTING RIGHTS, MANAGEMENT AND CONTROL.  Holders of KMEP Common Units
will have only limited voting rights on matters affecting KMEP. The KM General
Partner will manage and control the activities of KMEP. See "Description of KMEP
Partnership Agreement--Management." Holders of KMEP Common Units have no right
to elect the KM General Partner on an annual or other ongoing basis. If the KM
General Partner withdraws, however, its successor may be elected by the holders
of a majority of
 
                                       32
<PAGE>
the outstanding KMEP Common Units (excluding for purposes of such determination
KMEP Common Units owned by the departing general partner and its affiliates).
 
    The KM General Partner may not be removed unless such removal is approved by
the vote of the holders of not less than 66 2/3% of the outstanding KMEP Common
Units, excluding KMEP Common Units owned by the KM General Partner and its
affiliates, provided that certain other conditions are satisfied. Any such
removal is subject to the limited partners approving the successor general
partner by the same vote required for removing the KM General Partner and
receipt of an opinion of counsel that such removal and the approval of a
successor will not result in the loss of the limited liability of any limited
partner or cause KMEP to be treated as an association taxable as a corporation
or otherwise taxed as an entity for federal income tax purposes. In addition,
any KMEP Common Units held by a person (other than the KM General Partner and
its affiliates) that owns 20% or more of the KMEP Common Units cannot be voted.
These provisions mean that holders of KMEP Common Units only have a limited say
in matters affecting the operation of KMEP and, if such holders are in
disagreement with the decisions of the KM General Partner, they may remove the
KM General Partner only as provided in the KMEP Partnership Agreement.
 
    THE KM GENERAL PARTNER'S LIABILITY TO KMEP AND THE HOLDERS OF KMEP COMMON
UNITS MAY BE LIMITED. Certain provisions of the KMEP Partnership Agreement
contain exculpatory language purporting to limit the liability of the KM General
Partner to KMEP or the holders of KMEP Common Units. For example, the KMEP
Partnership Agreement provides that:
 
       (i) borrowings by KMEP or the approval thereof by the KM General Partner
    will not constitute a breach of any duty of the KM General Partner to KMEP
    or the holders of KMEP Common Units whether or not the purpose or effect
    thereof is to increase incentive distributions to the KM General Partner;
 
       (ii) any actions taken by the KM General Partner consistent with the
    standards of reasonable discretion set forth in the definitions of Available
    Cash and Cash from Operations contained in the KMEP Partnership Agreement
    will be deemed not to breach any duty of the KM General Partner to KMEP or
    the holders of KMEP Common Units; and
 
       (iii) in the absence of bad faith by the KM General Partner, the
    resolution of conflicts of interest by the KM General Partner will not
    constitute a breach of the KMEP Partnership Agreement or a breach of any
    standard of care or duty.
 
    KMEP PARTNERSHIP AGREEMENT LIMITS THE LIABILITY AND MODIFIES THE FIDUCIARY
DUTIES OF THE KM GENERAL PARTNER UNDER DELAWARE LAW.  Provisions of the KMEP
Partnership Agreement purport to limit the liability of the KM General Partner
to KMEP and the holders of KMEP Common Units. Such provisions also purport to
modify the fiduciary duty standards to which the KM General Partner would
otherwise be subject under Delaware law, under which a general partner owes its
limited partners the highest duties of good faith, fairness and loyalty. Such
duty of loyalty would generally prohibit a general partner of a Delaware limited
partnership from taking any action or engaging in any transaction as to which it
has a conflict of interest. The KMEP Partnership Agreement permits the KM
General Partner to exercise the discretion and authority granted to it
thereunder in the management of KMEP and the conduct of its operations, so long
as its actions are in, or not inconsistent with, the best interests of KMEP.
Such modifications of state law standards of fiduciary duty may significantly
limit the ability of holders of KMEP Common Units to successfully challenge the
actions of the KM General Partner as being a breach of what would otherwise have
been a fiduciary duty.
 
    POTENTIAL LIABILITY OF THE HOLDERS OF KMEP COMMON UNITS TO REPAY
DISTRIBUTIONS.  Holders of KMEP Common Units will not be liable for assessments
in addition to their initial capital investment in the KMEP Common Units. Under
certain circumstances, however, holders of KMEP Common Units may be required to
repay to KMEP amounts wrongfully returned or distributed to them. Under the
Delaware Act,
 
                                       33
<PAGE>
a limited partnership may not make a distribution to a partner to the extent
that at the time of the distribution, after giving effect to the distribution,
all liabilities of the partnership, other than liabilities to partners on
account of their partnership interests and nonrecourse liabilities, exceed the
fair value of the assets of the limited partnership. The Delaware Act provides
that a limited partner who receives such a distribution and knew at the time of
the distribution that the distribution was in violation of the Delaware Act will
be liable to the limited partnership for the amount of the distribution for
three years from the date of the distribution. Under the Delaware Act, an
assignee who becomes a substituted limited partner of a limited partnership is
liable for the obligations of the assignor to make contributions to the
partnership, except the assignee is not obligated for liabilities unknown to him
at the time he or she became a limited partner and which could not be
ascertained from the partnership agreement.
 
    POTENTIAL LIABILITY OF HOLDERS OF KMEP COMMON UNITS IF KMEP HAS NOT COMPLIED
WITH A STATE PARTNERSHIP LAW.  Following consummation of the Transaction, it is
anticipated that KMEP will conduct its business in 15 states, and in some of
those states the limitations on the liability of limited partners for the
obligations of a limited partnership have not been clearly established. If (i) a
court or governmental agency determined that KMEP was conducting business in any
such state and had not complied with the applicable limited partnership statute,
or (ii) the right of holders of KMEP Common Units as a group to remove or
replace the KM General Partner or to take other action pursuant to the KMEP
Partnership Agreement, and the exercise of such right or the taking of such
action constituted "control" of KMEP's business, then holders of KMEP Common
Units might be held liable for KMEP's obligations to the same extent as a
general partner.
 
    KMEP MAY EXERCISE ITS LIMITED CALL RIGHT.  In the event that at any time not
more than 20% of the issued and outstanding limited partners' interests of any
class of KMEP are held by persons other than the KM General Partner and its
affiliates, the KM General Partner will have the right, assignable to any of its
affiliates or to KMEP, to purchase all, but not less than all, of the remaining
limited partner interests of such class of KMEP held by such unaffiliated
persons, for a price equal to the most recent 20-day average trading price, or
the highest purchase price paid by the KM General Partner or its affiliates to
acquire limited partner interests of such class of KMEP during the prior 90
days, whichever is higher. As a consequence, a holder of such limited partner
interests may have such holder's interest purchased even though the holder may
not desire to sell it, or the price paid may be less than the amount the holder
would desire to receive.
 
    KMEP MAY SELL ADDITIONAL LIMITED PARTNER INTERESTS, DILUTING EXISTING
INTERESTS OF HOLDERS OF KMEP COMMON UNITS.  The KMEP Partnership Agreement
authorizes the KM General Partner to cause KMEP to issue additional limited
partner interests and other equity securities of KMEP for such consideration and
on such terms and conditions as shall be established by the KM General Partner.
Any issuance of additional KMEP Common Units or other equity securities of KMEP
would result in a corresponding decrease in the proportionate ownership interest
in KMEP represented by KMEP Common Units then outstanding, and such issuance
could therefore adversely affect the amount of cash distributed with respect to,
and the market price of, KMEP Common Units outstanding prior to such issuance.
Such additional issuances will also diminish the relative voting strength of the
previously outstanding KMEP Common Units.
 
    EFFECTS OF ANTI-TAKEOVER PROVISIONS.  The KMEP Partnership Agreement
provides that any person or group (other than the KM General Partner and its
affiliates) that acquires beneficial ownership of 20% or more of the KMEP Common
Units will lose its voting rights with respect to all of its KMEP Common Units.
This provision is intended to discourage a person or group from attempting to
remove the KM General Partner or otherwise change management of KMEP and may
diminish the price at which the KMEP Common Units will trade under certain
circumstances. For example, the provision may make it unlikely that a third
party, in an effort to remove the KM General Partner and take over the
management
 
                                       34
<PAGE>
of KMEP, would make a tender offer for the KMEP Common Units at a price above
their trading market price without first removing the KM General Partner and
substituting an affiliate.
 
    PRE-EMPTIVE RIGHTS OF GENERAL PARTNER.  To maintain its then current
partnership interest in KMEP, the KM General Partner, acting as general partner
of KMEP, has the right to purchase additional limited partnership interests
issued by KMEP whenever, and on the same terms that, KMEP issues such securities
to any person other than the KM General Partner and its affiliates. No other
holder of KMEP Common Units has a similar right. Therefore, only the KM General
Partner may protect itself against the dilutive effect of an issuance of
additional equity securities of KMEP. The KM General Partner has waived its pre-
emptive right in connection with the Transaction, but not with respect to any
other or further transaction.
 
POTENTIAL CONFLICTS OF INTEREST
 
    Certain conflicts of interest could arise among the KM General Partner,
Kinder Morgan Inc., the parent company of the KM General Partner ("KMI") and
KMEP. Such conflicts may include, among others, the following situations:
 
        (i) KMEP does not have any employees and relies solely on employees of
    the KM General Partner and its affiliates, including KMI.
 
        (ii) Under the terms of the KMEP Partnership Agreement, KMEP reimburses
    the KM General Partner for costs incurred in managing and operating KMEP.
 
   
        (iii) The amount of cash expenditures, borrowings and reserves in any
    quarter may affect whether or the extent to which there is sufficient
    Available Cash constituting Cash from Operations to pay quarterly
    distributions on the KMEP Common Units in such quarter or subsequent
    quarters. The KM General Partner has announced its intention to increase the
    annual distribution from $2.00 per KMEP Common Unit to $2.25 per KMEP Common
    Unit commencing with the distribution payable with respect to the fourth
    quarter of 1997; however, the ability of KMEP to continue to make
    distributions at such level depends upon the operations of KMEP and various
    factors which cannot be guaranteed. See "--Cash Distributions will Fluctuate
    with Performance; No Minimum Distribution."
    
 
        (iv) Whenever possible, the KM General Partner intends to limit the
    liability under contractual arrangements of KMEP to all or particular assets
    of KMEP, with the other party to the contract having no recourse against the
    KM General Partner or its assets. The KMEP Partnership Agreement provides
    that any action by the KM General Partner in so limiting its liability or
    that of KMEP will not be deemed to be a breach of its fiduciary duty, even
    if KMEP could have obtained more favorable terms without such limitation on
    liability.
 
        (v) Under the terms of the KMEP Partnership Agreement, the KM General
    Partner is not restricted from paying its affiliates for any services
    rendered on terms fair and reasonable to KMEP or entering into additional
    contractual arrangements with any of the affiliates of the KM General
    Partner on behalf of KMEP. Neither the KMEP Partnership Agreement nor any of
    the other agreements, contracts and arrangements between KMEP, on the one
    hand, and the KM General Partner and its affiliates, on the other hand, are
    or will be the result of arm's-length negotiations.
 
        (vi) The KMEP Partnership Agreement provides that it will not constitute
    a breach of the KM General Partner's fiduciary duty if the KM General
    Partner exercises its right to call for and purchase limited partner
    interests as provided in the KMEP Partnership Agreement or assigns this
    right to one of its affiliates or to KMEP.

                                  THE PARTIES
 
KMEP
 
    GENERAL.  KMEP, a Delaware limited partnership, was organized in August 1992
to acquire and operate the natural gas liquids pipelines of Enron Corp. Through
its three operating limited partnerships, KMEP manages a diversified portfolio
of midstream energy assets. It is the sole owner and operator of three pipeline
systems, which transport NGLs, refined petroleum products and CO(2) (the "KMEP
Pipeline System") and two modern, high-speed coal terminaling facilities (the
"Coal Terminals"). KMEP also owns an indirect 25% interest in a Y-grade
fractionation facility.
 
    BUSINESS STRATEGY.  On February 14, 1997, the current management of KMEP
acquired the stock of the KM General Partner from Enron Corp. The current
management's business strategy is to operate KMEP as a growth-oriented publicly
traded limited partnership by reducing operating costs, better utilizing and
expanding its asset base, and making selective, strategic acquisitions that are
accretive to KMEP Common Unit holders. Management believes that KMEP is well
positioned to expand its present assets and make strategic acquisitions that are
accretive in cash flow to KMEP Common Unit holders.
 
    During the nine months ended September 30, 1997, KMEP has decreased its
operating costs by $3.1 million compared to the same period for 1996. Earnings
for the nine months ended September 30, 1997 totaled $10.0 million, compared to
$6.5 million for the comparable period in 1996, an increase of 54%.
Distributions to KMEP Common Unit holders for the third quarter of 1997 was
$0.50 per KMEP Common Unit (reflecting the two for one common unit split that
occurred on October 1, 1997), an increase of 59% compared to the distribution of
$0.315 (adjusted for the common unit split) for the third quarter of 1996.
 
    KMEP management believes that substantial growth opportunities exist in all
of KMEP's core businesses: (i) products pipelines, (ii) coal terminals, storage
and services; and (iii) CO(2) transportation and services. In August, 1997, KMEP
acquired a coal terminaling and storage facility located on the Kentucky river
and in the fall of 1997 completed a major expansion of its Cora Terminal. As a
result, KMEP has expanded its coal terminaling and storage capacity by
approximately 100%. See "--Coal Operations." In October 1997, KMEP announced its
intention to form Shell CO(2) Company with Shell Western, which will explore,
produce, market and transport CO(2) for enhanced oil recovery throughout the
continental United States. See "--Central Basin Pipeline."
 
    The Transaction should further KMEP's strategy of increasing KMEP Common
Unit holder value, because management believes that it will be accretive to
KMEP's earnings and cash flow. In addition, the Transaction should provide KMEP
with additional expansion and extension opportunities. Significant cost savings
are also expected to be derived from the combination. However, there can be no
assurances that such opportunities and cost savings will be realized. Upon
consummation of the Transaction, KMEP will be one of the largest common carrier
products pipeline systems in terms of volume of deliveries, barrel miles and
pipeline mileage in the United States, with over 5,000 miles of trunk pipeline
serving 15 states.
 
    Management believes that the provisions of the KMEP Partnership Agreement
provide it with financial incentives that are closely aligned with those of the
holders of KMEP Common Units. Specifically, when KMEP issues equity in
connection with an acquisition (E.G., the Transaction), the KM General Partner
must contribute additional capital. In addition, the incentive distribution
structure in the KMEP Partnership Agreement provides the KM General Partner with
a strong incentive to distribute as much cash from operations as possible.
 
    THE NORTH SYSTEM.  The North System is the largest of KMEP's pipeline
systems. It is an approximate 1,600 mile interstate common carrier pipeline
system that extends from South Central Kansas to the Chicago area. Products
transported on the North System include NGLs (E.G. ethane, propane, normal
butane, isobutane and natural gasoline) and refined petroleum products such as
gasoline and fuel oils. Product shipments fall into three general categories
including (i) shipments of NGLs from South Central
 
                                       36
<PAGE>
Kansas (a major hub for producing and storing NGLs) to markets in the Midwest,
including major refineries in the Chicago area, propane terminals in Nebraska,
Iowa and Illinois, and to other pipeline systems; (ii) shipments of refinery
grade normal butane produced in the Chicago area for storage near Bushton,
Kansas and the subsequent return of those volumes to the Chicago area; and (iii)
shipments of refined petroleum products through KMEP's 50% interest in the
Heartland Partnership to terminals in Nebraska and Iowa. The North System
competes for business with other liquids pipelines and to a lesser extent rail
transporters. The North System operated at approximately 59% of capacity in
1995, 66% of capacity in 1996 and 70% of capacity in the first nine months of
1997.
 
    In addition to the pipelines, the North System includes seven propane truck
loading terminals plus a multi-terminal complex at Morris, Illinois. KMEP owns
and operates several tank and cavern storage facilities with approximately 1.0
MMBbls of capacity and has a long-term lease for cavern storage near Bushton,
Kansas for approximately 5.0 MMBbls of capacity.
 
    CYPRESS PIPELINE.  Completed in April 1991, the Cypress Pipeline is a
104-mile interstate common carrier pipeline that transports purity ethane from
the NGL hub in Mont Belvieu, Texas to a major petrochemical producer in Lake
Charles, Louisiana. The pipeline was originally built with a capacity of
approximately 37 MBbls/d but has recently completed an expansion which increases
the capacity to 57 MBbls/d. It has the capability to transport other NGLs. The
Cypress Pipeline operates under a long-term transportation agreement which
expires in 2011. Under the terms of that agreement, the petrochemical producer
has a fixed tariff, ship-or-pay obligation for a minimum of 30 MBbls/d through
2011. In addition, the petrochemical producer has entered into a five-year
ship-pay obligation for an additional 14 MBbls/d.
 
    CENTRAL BASIN PIPELINE.  Placed in service in 1985, the Central Basin
Pipeline transports CO(2) to enhanced oil recovery projects throughout the
Permian Basin in West Texas. Central Basin originates in Denver City, Texas
where it interconnects with all three major supply pipelines from Colorado and
New Mexico (the Cortez, Bravo and Sheep Mountain Pipelines). The mainline runs
approximately 143 miles and terminates near McCamey, Texas where it
interconnects with another pipeline. In addition, approximately 157 miles of
lateral supply lines connect the mainline to approximately 20 enhanced oil
recovery projects. The pipeline transported an average of 196 Mmcf/day for the
first nine months of 1997. This represents approximately 33% of the pipeline's
current unpowered capacity of 600 Mmcf/day.
 
   
    On October 27, 1997, KMEP entered into a letter of intent with Shell Western
to form Shell CO(2) Company, which will explore, produce, market and transport
CO(2) for enhanced oil recovery throughout the continental United States. KMEP
is expected to receive a 20% interest in Shell CO(2) Company by contributing the
Central Basin Pipeline and approximately $25 million in cash. The transaction is
subject to certain conditions, including the execution of a definitive
partnership agreement, and certain regulatory approvals. Closing of the
transaction with Shell Western is anticipated to occur in the first quarter of
1998. See "Risk Factors--Risks Associated with Shell CO(2) Company" and
"Unaudited KMEP Pro Forma Financial Information" for additional information with
respect to Shell CO(2) Company.
    
 
    COAL OPERATIONS.  KMEP owns and operates two coal transloading facilities
which transload, store and blend Western and Illinois Basin coals for various
utilities and other customers on the inland waterways. Through its Red Lightning
Energy Services unit, KMEP markets coal and energy-related services.
 
    The Cora Terminal is strategically located near the end of the Union Pacific
mainline on approximately 480 acres of land along the Mississippi River near
Cora, Illinois. The terminal has an effective capacity of approximately 15
million tons per year, and it can be expanded to 20 million tons with certain
capital additions. The terminal typically receives coal via train and loads coal
onto barges, but is also capable of both receiving and shipping by truck. Most
of the coal transloaded at the facility is done under multi-year contracts with
four customers.
 
                                       37
<PAGE>
    On September 4, 1997, KMEP completed its purchase of Grand Rivers Terminal,
a coal transloading and storage facility on the Tennessee River, just above the
Kentucky dam. Commencing October 1, 1997, Grand Rivers began operating under a
five year agreement with the Tennessee Valley Authority to transload, store and
blend between a minimum of 5 million and a maximum of 12 million tons annually.
The terminal can both receive and ship coal from trains, trucks or barges, and
has an effective annual capacity of approximately 25 million tons.
 
    FRACTIONATOR.  KMEP owns an indirect 25% interest in the Mont Belvieu
Fractionator, located approximately 20 miles east of Houston in Mont Belvieu,
Texas. The fractionator is a 200 MBbls/d capacity Y-grade fractionation facility
that produces a range of specification products, including ethane, propane,
normal butane, isobutane and natural gasoline. The facility is operated by
Enterprise Products Company and has operated at approximately 95.3% of capacity
during the first nine months of 1997.
 
   
    ORGANIZATIONAL STRUCTURE.  The KM General Partner serves as the sole general
partner of KMEP. In addition to its general partner interest in KMEP, as of
January 15, 1998, the KM General Partner owns approximately 6.1% of the KMEP
Common Units, before giving effect to the Transaction. KMEP is the approximate
99% limited partner of each of the KMEP Operating Partnerships and the KM
General Partner is the approximate 1% general partner. In connection with the
Transaction, KMEP will form OLP-D, of which KMEP will be the approximate 99%
limited partner and the KM General Partner will be the approximate 1% general
partner. Following the consummation of the Transaction and the Special
Distribution, OLP-D will be the sole general partner of, and will own a 99.5%
general partner interest in, the SF Operating Partnership and the SF General
Partner will own the .5% Special LP Interest. As a result of its 1% general
partner interest in KMEP and its approximate 1% general partner interest in each
of the KMEP Operating Partnerships and OLP-D, the KM General Partner will have a
2% economic interest in the assets of KMEP and Santa Fe. In addition, the KM
General Partner is entitled to receive quarterly cash incentive distributions
from KMEP, which increase based on the amount of quarterly cash distributions
paid to holders of KMEP Common Units.
    
 
   
    KMEP's headquarters and executive offices are located at 1301 McKinney
Street, Suite 3450, Houston, Texas 77010 and its telephone number is (713)
844-9500.
    
 
SANTA FE
 
    GENERAL.  Santa Fe is a Delaware limited partnership formed in 1988 to
acquire and operate, through the SF Operating Partnership, the refined petroleum
products pipeline business of Santa Fe Pacific Corporation, a Delaware
corporation.
 
   
    Santa Fe transports refined petroleum products, including gasoline, diesel
fuel and commercial and military jet fuel, via pipeline, primarily for major
petroleum companies, independent refiners, the United States military and
marketers and distributors of such products. Santa Fe also operates 13 truck
loading terminals and provides pipeline service to approximately 44
customer-owned terminals, three commercial airports and 12 military bases. Santa
Fe's pipelines (collectively, the "SF Pipeline System") are: (1) the South Line,
which is composed of two segments, the West Line, which transports products from
Los Angeles to Phoenix and Tucson, Arizona and various intermediate points, and
the East Line, which transports products from El Paso, Texas to Tucson, Phoenix
and various intermediate points; (2) the North Line, which transports products
primarily from the San Francisco Bay area to various cities in northern
California and western Nevada; (3) the Oregon Line, which transports products
between Portland and Eugene, Oregon; and (4) the San Diego Line, which
transports products from Los Angeles to San Diego, California and various
intermediate points. Santa Fe also owns certain other lines that can be used to
connect refinery, terminal or storage facilities to pipeline or other
facilities, some of which are dedicated to use for a specific customer and some
of which have been leased to or are operated by other parties.
    
 
                                       38
<PAGE>
   
    MARKETS.  Santa Fe currently serves approximately 65 shippers in the refined
products market, with the largest customers consisting of major petroleum
companies, independent refiners, the United States military and independent
marketers and distributors of products. The volume of products transported in
the SF Pipeline System is directly affected by the level of end-user demand for
such products in the geographic regions served by Santa Fe. Such market demand
varies based upon the different end uses to which the products delivered through
the SF Pipeline System may be applied. A substantial portion of product volumes
transported in the SF Pipeline System is gasoline, the demand for which is
dependent on such factors as prevailing economic conditions and demographic
changes in the markets served by the SF Pipeline System and, to a lesser degree,
gasoline prices. Portions of Santa Fe's business can experience seasonal
variations; however, overall volumes are only moderately seasonal, with lower
than average volumes typically being transported during the first and fourth
quarters of each year.
    
 
    PRINCIPAL CUSTOMERS.  Of the approximately 65 shippers served by Santa Fe on
a system-wide basis in 1996, the largest shippers on each of the pipeline
segments were generally the same entities. The chart below reflects the
percentage of transportation revenues attributable to the top 10 shippers on the
South Line, North Line, Oregon Line and San Diego Line during each of the
periods indicated, based upon total product volumes shipped during the years
indicated.

    Between 73% and 74% of the refined petroleum products transported in the SF
Pipeline System during each of the calendar years 1994 through 1996 were shipped
by major petroleum companies. Operating revenues received from ARCO Products
Company and Chevron U.S.A. Products Company accounted for 14.8% and 12.1%,
respectively, of total 1996 revenues. These two customers accounted for 16.3%
and 13.3%, respectively, of total 1995 revenues, and for 16.1% and 12.4%,
respectively, of total 1994 revenues.
 
   
    Products delivered to military facilities accounted for 4.0%, 4.5% and 4.8%
of total volumes shipped by Santa Fe during 1996, 1995 and 1994, respectively.
Military volumes are dependent on the level of activity at military bases served
by the SF Pipeline System. Since 1991, the United States Congress has approved
plans to reduce the overall level of military activity. As of year-end 1996,
several military bases historically served by Santa Fe had been closed and
realignment of certain other bases continues to occur, with the level of
activity having decreased at certain bases and increased at others. No other
bases served by Santa Fe have been identified for closure or realignment. In
January 1996, Santa Fe acquired a pipeline serving Lemoore Naval Air Station,
near Fresno, California.
    
 
   
    DESCRIPTION OF THE SF PIPELINE SYSTEM.  The South Line consists of two
pipeline segments, the West Line and the East Line.
    
 
   
    The West Line consists of approximately 555 miles of primary pipeline and
currently transports products for approximately 50 shippers from three pipeline
origin stations in the Los Angeles Basin to Phoenix and Tucson, Arizona and
various intermediate commercial and military delivery points. In 1996, 1995 and
1994, the West Line transported averages of 339,900, 333,400 and 325,600 barrels
per day, respectively, of which averages of 114,100, 111,700 and 104,000 barrels
per day, respectively, were delivered to Phoenix and Tucson. Also, a significant
portion of West Line volumes are transported to
    
 
                                       39
<PAGE>
Colton, California for local distribution and for delivery to Calnev Pipeline,
an unaffiliated common carrier of refined petroleum products to Las Vegas,
Nevada and intermediate points. The West Line serves Santa Fe terminals located
in Colton and Imperial, California as well as in Phoenix and Tucson.
 
    The East Line is comprised of two parallel lines originating in El Paso,
Texas and continuing approximately 300 miles west to the Tucson terminal and one
line continuing northwest approximately 130 miles from Tucson to Phoenix. All
products received by the East Line at El Paso come from a refinery in El Paso or
are delivered through connections with non-affiliated pipelines from refineries
in Odessa and Dumas, Texas and Artesia, New Mexico. The East Line transports
refined petroleum products for approximately 17 shippers. In 1996, 1995 and
1994, the East Line transported averages of 73,700, 67,200 and 69,300 barrels
per day, respectively, of refined petroleum products, of which averages of
35,800, 31,500 and 34,100 barrels per day, respectively, were delivered to
Phoenix. Since August 1992, when the second phase of the East Line expansion
became operational, the daily pumping capacity between El Paso and Tucson has
been approximately 95,000 barrels, and the daily pumping capacity from Tucson to
Phoenix has been approximately 55,000 barrels. The East Line serves Santa Fe
terminals located in Tucson and Phoenix.
 
    In late 1995, Diamond Shamrock, Inc. completed construction of a new 10-inch
diameter products pipeline from its refinery near Dumas, Texas to El Paso. In
late 1996, Diamond Shamrock connected this pipeline to Santa Fe's East Line and
began shipping products to Tucson and Phoenix.
 
    Longhorn Partners Pipeline is a proposed joint venture project which would
acquire and convert an existing crude oil pipeline to refined products service
and construct a new pipeline extension to transport refined products from
refineries on the Gulf Coast to El Paso and other destinations in Texas.
 
    Increased product supply in the El Paso area could result in some shift of
volumes transported into Arizona from Santa Fe's West Line to its East Line.
While increased movements into the Arizona market from El Paso displace higher
tariff volumes supplied from Los Angeles on the West Line, such shift of supply
sourcing has not had, and is not expected to have, a material effect on Santa
Fe's results of operations.
 
    The North Line of the SF Pipeline System consists of approximately 1,075
miles of pipeline in six pipeline segments originating in Richmond, Concord and
Bakersfield, California. This line serves Santa Fe terminals located in
Brisbane, Bradshaw, Chico, Fresno and San Jose, California, and Sparks, Nevada.
The North Line delivers refined petroleum products for approximately 40
shippers. A substantial portion of the products delivered through the North Line
comes from refineries in the San Francisco Bay area. A small percentage of
supply is received from various pipeline and marine terminals that deliver
products from foreign and domestic ports. Substantially all of the products
shipped through the Bakersfield-Fresno segment of the North Line are supplied by
a refinery located in Bakersfield.
 
    The Oregon Line is a 114-mile pipeline serving approximately 10 shippers.
The Oregon Line receives products from marine terminals in Portland and from
Olympic Pipeline, a non-affiliated carrier, which transports products from the
Puget Sound area to Portland. From its origination point in Portland, the Oregon
Line extends south and serves the Santa Fe terminal located in Eugene, Oregon.
 
   
    The San Diego Line is a 135-mile pipeline serving major population areas in
Orange county (immediately south of Los Angeles) and San Diego. Approximately 20
shippers transport products on this line, which is supplied by the same
refineries and terminals that supply the West Line and extends south to serve
Santa Fe terminals in the cities of Orange and San Diego.
    
 
    DESCRIPTION OF THE SANTA FE TRUCK LOADING TERMINALS.  Santa Fe's operations
include 13 truck loading terminals with an aggregate usable tankage capacity of
approximately 8.2 million barrels. Terminals are located at destination points
on each of the lines as well as at certain intermediate points along each line
where deliveries are made. These terminals furnish short-term product storage,
truck loading and ancillary services, such as vapor recovery, additive
injection, oxygenate blending, and quality control. The truck
 
                                       40
<PAGE>
   
loading capacity of the terminals ranges from two to 12 trucks at a time.
Between 128 million and 129 million barrels of products were delivered to
commercial customers at such terminals during each of the past three years,
resulting in Santa Fe storage and terminaling revenues of $35.0 million, $34.3
million and $33.8 million during the years 1996, 1995 and 1994, respectively.
    
 
    Capacity of Santa Fe's terminaling facilities varies through out its
pipeline system. Santa Fe does not own terminal facilities at all pipeline
delivery locations. At certain locations, product deliveries are made to
facilities owned by shippers or independent terminal operators.
 
    Truck loading and other terminal services are provided by Santa Fe as an
additional service, and a separate fee (in addition to transportation tariffs)
is charged. Rates charged for terminaling services are not economically
regulated by the FERC or any state agency.
 
    LEGAL PROCEEDINGS.  Additional information with respect to Santa Fe's
current legal proceedings are included in Santa Fe's annual and quarterly
reports filed with the Commission, which are incorporated herein by reference.
 
   
    FERC Proceedings. In September 1992, El Paso Refinery, L.P. ("El Paso")
filed a protest/complaint with FERC challenging Santa Fe's East Line rates from
El Paso, Texas to Tucson and Phoenix, Arizona, challenging Santa Fe's proration
policy and seeking to block the reversal of the direction of flow of Santa Fe's
six-inch pipeline between Phoenix and Tucson. At various dates following El
Paso's September 1992 filing, other shippers on Santa Fe's South System,
including Chevron U.S.A. Products Company ("Chevron"), Navajo, ARCO Products
Company ("ARCO"), Texaco Refining and Marketing Inc. ("Texaco"), Refinery
Holding Company, L.P. (a partnership formed by El Paso's long-term secured
creditors that purchased El Paso's refinery in May 1993), Mobil Oil Corporation
and Tosco Corporation, have filed separate complaints, and/or motions to
intervene in the FERC proceeding, challenging Santa Fe's rates on its East and
West Lines. Certain of these parties also claimed that a gathering enhancement
charge at Santa Fe's Watson origin pump station in Carson, California is in
violation of the Interstate Commerce Act. In subsequent procedural rulings, the
FERC has consolidated these challenges (Docket Nos. OR92-8-000, ET AL.) and
ruled that they must proceed as a complaint proceeding, with the burden of proof
being placed on the complaining parties. Such parties must show that Santa Fe's
rates and practices at issue violate the requirements of the Interstate Commerce
Act.
    
 
    Hearings in the FERC proceeding commenced on April 9, 1996 and concluded on
July 19, 1996. The parties completed the filing of their post-hearing briefs on
December 9, 1996. An initial decision by the FERC Administrative Law Judge was
issued on September 25, 1997 (the "Initial Decision").
 
    The Initial Decision upheld Santa Fe's position that "changed circumstances"
were not shown to exist on the West Line, thereby retaining the just and
reasonable status of all West Line rates that were "grandfathered" under the
Energy Policy Act of 1992 ("EPACT"). Accordingly, such rates are not subject to
challenge, either for the past or prospectively, in that proceeding. The
Administrative Law Judge's decision specifically excepted from that ruling Santa
Fe's Tariff No. 18 for movement of jet fuel from Los Angeles to Tucson, which
was initiated subsequent to the enactment of EPACT.
 
   
    The Initial Decision also included rulings that were generally adverse to
Santa Fe on such cost of service issues as the capital structure to be used in
computing Santa Fe's 1985 starting rate base under FERC Opinion 154-B, the level
of income tax allowance, and the recoverability of civil and regulatory
litigation expense and certain pipeline reconditioning costs. The Administrative
Law Judge also ruled that a gathering enhancement service at Santa Fe's Watson
origin pump station in Carson, California is subject to FERC jurisdiction and
ordered that a tariff for that service and supporting cost of service
documentation be filed no later than 60 days after a final FERC order on this
matter.
    
 
   
    Briefs on exceptions were filed on November 25, 1997, and briefs opposing
exceptions are scheduled to be filed by the end of January 1998. The matters at
issue will then be submitted to the FERC commissioners for a final decision,
which decision is not expected before late-1998. Unless the FERC's
    
 
                                       41
<PAGE>
   
final decision is substantially more favorable to Santa Fe's position on the
above-described methodological issues than the Initial Decision, Santa Fe will
be required to pay reparations and file reduced tariff rates, primarily on the
East Line, within approximately 60 days of the issuance of that final decision
unless delayed by preparation and review of a compliance filing. If the Initial
Decision were affirmed in current form by the FERC, Santa Fe management
estimates that the total reparations and interest that would be payable as of
December 31, 1997 would approximate the $30 million in reserves that had been
recorded as of that date. Santa Fe management also estimates that the Initial
Decision, in its current form, and if also applied to the Sepulveda Lines rate
at issue in Docket No. IS98-1-000, would reduce prospective revenues in the
range of $8 millon to $10 million annually. Reparations and interest will
continue to accrue at approximately $8 million per annum until new prospective
rates become effective. If Santa Fe were to lose its "grandfathered" rates due
to a finding of "changed circumstances," the losses to Santa Fe, or KMEP after
the consummation of the Transaction, could be substantially larger. As a result,
the loss of Santa Fe's "grandfathered" rates could have a material adverse
effect on Santa Fe's or, after the Transaction is consummated, KMEP's ability to
make distributions to Unit holders.
    
 
   
    Prior to issuance of the Initial Decision, Santa Fe announced that it had
reached tentative agreements with two complainants in Docket Nos. OR92-8-000 ET
AL., resolving those parties' claims in that proceeding. Santa Fe management
does not anticipate that those agreements will be finalized in accordance with
their tentative terms.
    
 
   
    In December 1995, Texaco filed an additional FERC complaint, which involves
the question of whether a tariff filing is required for movements on certain of
Santa Fe's lines upstream of its Watson, California station origin point (the
"Sepulveda Lines") and, if so, whether those rates may be set in that proceeding
and what those rates should be. Texaco's initial complaint was followed by
several other West Line shippers filing similar complaints and/or motions to
intervene, all of which have been consolidated into Docket Nos. OR96-2-000 ET
AL. Hearings before an Administrative Law Judge were held in December 1996 and
the parties completed the filing of final post-hearing briefs on January 31,
1997.
    
 
   
    On March 28, 1997, the Administrative Law Judge issued an initial decision
holding that the movements on Santa Fe's Sepulveda Lines are not subject to FERC
jurisdiction. On August, 5, 1997, the FERC reversed that decision and found the
Sepulveda Lines to be subject to the jurisdiction of the FERC. Santa Fe was
ordered to make a tariff filing within 60 days to establish an initial rate for
these facilities. On October 6, 1997, Santa Fe filed a tariff establishing the
initial interstate rate for movements on the Sepulveda Lines from Sepulveda
Junction to Watson Station at the preexisting rate of five cents per barrel,
along with supporting cost of service documentation. Subsequently, several
shippers filed protests and motions to intervene at the FERC challenging that
rate. On October 27, 1997, Santa Fe made a responsive filing at the FERC,
requesting that these protests be held in abeyance until the FERC ruled on Santa
Fe's request for rehearing of the August 5, 1997 order, and also indicating that
Santa Fe intended to defend the new tariff both on the basis of its cost of
service and as a market-based rate. On November 5, 1997, the FERC issued an
order accepting the new rate effective November 6, 1997, subject to refund, and
referred the proceeding to a settlement judge. On December 10, 1997, following a
settlement conference held at the direction of the FERC, the settlement judge
recommended that the settlement procedures be terminated. On December 24, 1997,
FERC denied Santa Fe's request for rehearing of the August 5, decision. On
December 31, 1997, Santa Fe filed an application for market power determination,
which, if granted, will enable it to charge market-based rates for this service.
    
 
   
    On October 22, 1997, ARCO Products Company, Mobil Oil Corporation and Texaco
Refining and Marketing Inc. filed a new complaint at the FERC (Docket No.
OR98-1-000) challenging the justness and reasonableness of all of Santa Fe's
interstate rates. The new complaint again challenges Santa Fe's East and West
Line rates and raises many of the same issues, including a renewed challenge to
the grandfathered status of West Line rates, that have been at issue in Docket
Nos. OR92-8-000, ET AL. The new complaint includes an assertion that the
Transaction and the cost savings anticipated to result from the Transaction
constitute "changed circumstances" that provide a basis for terminating the
"grandfathered"
    
 
                                       42

status of Santa Fe's otherwise protected rates. The complaint also seeks to
establish that Santa Fe's grandfathered interstate rates from the San Francisco
Bay area to Reno, Nevada and from Portland to Eugene, Oregon are also subject to
"changed circumstances" and, therefore, can be challenged as unjust and
unreasonable. On November 26, 1997, Ultramar Diamond Shamrock Corporation filed
a similar complaint at the FERC (Docket No. OR98-2-000). Both reparations and
prospective rate reductions are sought for movements on all of the lines.
    
 
   
    Santa Fe filed answers to both complaints with the FERC on November 21, 1997
and December 22, 1997, respectively and intends to vigorously defend all of the
challenged rates. On January   , 1998, the FERC issued an order accepting the
complaints and consolidating both complaints into one proceeding, but holding
them in abeyance pending a Commission decision on review of the Initial Decision
in Docket Nos. OR92-8-000 ET AL. The FERC stated that it would, at that time,
afford the complainants the opportunity to amend their complaints in light of
any findings of the FERC in Docket Nos. OR92-8-000 ET AL. The FERC also stated
that the complainants should identify more specifically the specific services at
issue and the rates and charges upon which they are basing their claims for
relief. Santa Fe management has reviewed the filings and it is their position
that none of the matters raised in the new complaints should constitute "changed
circumstances" within the meaning of EPACT.
    
 
   
    Applicable rules and regulations in this field are vague, relevant factual
issues are complex and there is little precedent available regarding the factors
to be considered or the method of analysis to be employed in making a
determination of "changed circumstances," which is the showing necessary to make
"grandfathered" rates subject to challenge. Santa Fe and KMEP believe, after
consultation with FERC counsel, that the Transaction, standing alone, should not
be found to constitute "changed circumstances;" however, the realization of the
cost savings anticipated to arise from the Transaction may increase the risk of
a finding of "changed circumstances."
    
 
   
    If "changed circumstances" are found, Santa Fe rates previously
"grandfathered" under EPACT may lose their "grandfathered" status and, if such
rates are found to be unjust and unreasonable, shippers may be entitled to a
prospective rate reduction together with reparations for periods from the date
of the complaint to the date of the implementation of the new rates.
    
 
   
    Although there can be no assurance regarding the ultimate resolution of the
FERC proceedings, Santa Fe and KMEP believe (in light of numerous factors,
including the existing limited precedent, the Initial Decision of the
administrative law judge in the current proceeding, existing risks of litigation
unrelated to the Transaction, and policies of the FERC that favor and encourage
cost reductions by pipelines) that consummation of the Transaction and
realization of the anticipated cost savings should not have a material adverse
effect on their current ability to resolve the FERC cases. KMEP believes that
the final resolution of the FERC proceedings should not have a material adverse
effect on KMEP's results of operations, financial condition, liquidity and
ability to maintain distribution levels following the Closing. Santa Fe and KMEP
are not able to predict with certainty whether settlement agreements will be
completed with some or all of the complainants, the final terms of any such
settlement agreements that may be consummated, or the final outcome of the FERC
proceedings should they be carried through to their conclusion, and it is
possible that current or future proceedings could be resolved in a manner
adverse to KMEP. An adverse resolution could have a material adverse effect on
KMEP.
    
 
   
    In assessing the impact of the FERC proceedings on its evaluation of the
Transaction, the Special Committee attempted to weigh (i) the additional risk
that cost savings contemplated to result from the Transaction could lead to a
finding of "changed circumstances" and a loss of the "grandfathered" status of
Santa Fe's pipeline rates against (ii) the potential benefits of the
Transaction, including spreading the risk of a possible adverse outcome of the
FERC proceedings even in the absence of the Transaction over the broader group
of assets and the wider unitholder base that would result from the Transaction.
While the Special Committee has relied on the foregoing beliefs of the
managements of Santa Fe and KMEP in assessing the Transaction, the members of
the Special Committee are not experts on FERC matters and, accordingly, the
Special Committee cannot provide any independent assurance to holders of Santa
Fe

    California Public Utilities Commission Proceeding.  A complaint was filed
with the CPUC on April 7, 1997 entitled ARCO PRODUCTS COMPANY, MOBIL OIL
CORPORATION AND TEXACO REFINING AND MARKETING INC. VS. SFPP, L.P. The complaint
challenges rates charged by Santa Fe for intrastate transportation of refined
petroleum products through its pipeline system in the State of California and
requests prospective rate adjustments. On October 1, 1997, the complainants
filed testimony seeking prospective rate reductions aggregating approximately
$15 million per year. On November 26, 1997, Santa Fe filed responsive testimony
defending the justness and reasonableness of its rates. The rebuttal testimony
was filed on December 12, 1997 and hearings before the Administrative Law Judge
were completed on January 15, 1998. Briefing and oral argument will follow in
March 1998, with a Commission decision expected in the third quarter of 1998.
Management believes that Santa Fe has substantial defenses against the claims
raised in the complaint and intends to vigorously defend its California rates.
    
 
    Environmental Matters.  Since August 1991, Santa Fe, along with several
other respondents, has been involved in one cleanup ordered by the United States
Environmental Protection Agency ("EPA") related to ground water contamination in
the vicinity of the Santa Fe's storage facilities and truck loading terminal at
Sparks, Nevada. The EPA approved the respondents' remediation plan in September
1992 and the remediation system began operations in September 1995. In addition,
Santa Fe is presently involved in 18 ground water hydrocarbon remediation
efforts under administrative orders issued by the California Regional Water
Quality Control Board and two other state agencies.
 
    SPTC Easements.  Santa Fe and SPTC are engaged in a judicial reference
proceeding to determine the extent, if any, to which the rent payable by Santa
Fe for the use of pipeline easements on rights-of-way held by SPTC should be
adjusted pursuant to existing contractual arrangements (SOUTHERN PACIFIC
TRANSPORTATION COMPANY VS. SANTA FE PACIFIC CORPORATION, SFP PROPERTIES, INC.,
SANTA FE PACIFIC PIPELINES, INC., SFPP, L.P., ET AL., Superior Court of the
State of California for the County of San Francisco, filed August 31, 1994).
This matter was tried in the latter part of 1996 and the court issued its
Statement of Tentative Decision in January 1997. The Statement of Tentative
Decision indicated that the court intended to establish a new base annual rental
for the subject rights-of-way at a level, subject to inflation adjustments, that
is adequately provided for by the amounts that had been accrued by Santa Fe
through December 31, 1996.
 
    On May 7, 1997, the judge issued a Statement of Decision and Judgment that
reaffirmed the conclusions set forth in his January 1997 Statement of Tentative
Decision. This Statement of Decision and Judgment was filed on June 30, 1997
with the Superior Court for the County of San Francisco, under which court's
jurisdiction it is subject to appeal by SPTC. On May 30, 1997, SPTC filed a
motion for a new trial and the motion was denied on June 26, 1997. Motions of
Appeal were filed by SPTC and Santa Fe in July and August, 1997, respectively.
 
   
    ORGANIZATIONAL STRUCTURE.  The SF General Partner is the sole general
partner of each of the Santa Fe Partnerships. Prior to the consummation of the
Transaction, the SF General Partner has a 2% economic interest in the assets of
Santa Fe, as a result of its 1% general partner interest in Santa Fe and its
approximate 1% general partner interest in the SF Operating Partnership. In
addition, prior to the consummation of the Transaction, the SF General Partner
is entitled to receive quarterly cash incentive distributions from Santa Fe,
which increase based on the amount of quarterly cash distributions paid to
holders of Santa Fe Common Units. The SF General Partner also owns 8,148,148
Santa Fe Common Units, which is approximately the number of Santa Fe Common
Units into which the VREDs are exchangeable under certain circumstances. See
"The Transaction--VREDs." The SF General Partner is a wholly-owned subsidiary of
SF Holdings, which is an indirect subsidiary of BNSF.
    
 
   
    Santa Fe's headquarters and executive offices are located at 1100 Town &
Country Road, Orange, California 92868 and its telephone number is (714)

    This Joint Proxy Statement/Prospectus is being furnished to the holders of
KMEP Common Units in connection with the solicitation of proxies by the Board of
Directors of the KM General Partner for use at the KMEP Special Meeting to be
held on February 24, 1998, at Bracewell & Patterson, L.L.P., South Tower
Pennzoil Place, 711 Louisiana Street, Suite 2600, Houston TX 77002, commencing
at 10:30 a.m. local time, and any adjournment or postponement thereof.
    
 
   
    This Joint Proxy Statement/Prospectus is also being furnished to holders of
Santa Fe Common Units in connection with the solicitation of proxies by the
Board of Directors of the SF General Partner for use at the Santa Fe Special
Meeting to be held on February 24, 1998, at the Doubletree Hotel, 100 The City
Drive, Orange, California 92868 commencing at 9:00 a.m. local time, and at any
adjournment or postponement thereof.
    
 
MATTERS TO BE CONSIDERED AT THE MEETINGS
 
    KMEP.  At the KMEP Special Meeting, holders of the KMEP Common Units will
consider and vote upon the issuance of KMEP Common Units pursuant to, and in
accordance with the terms and conditions of, the Purchase Agreement.
 
   
    SANTA FE.  At the Santa Fe Special Meeting, holders of Santa Fe Common Units
will consider and vote upon the Santa Fe Proposal.
    
 
GENERAL PARTNERS' RECOMMENDATIONS
 
    KMEP.  The Board of the Directors of the KM General Partner has unanimously
approved the Transaction, including the adoption and approval of the Purchase
Agreement, the issuance of KMEP Common Units pursuant to the Purchase Agreement,
the consummation of the Transaction and the other matters contemplated by the
Purchase Agreement, and recommends that holders of KMEP Common Units vote FOR
approval of the KMEP Proposal.
 
    SANTA FE.  The Board of Directors of the SF General Partner and the Special
Committee have unanimously approved the Transaction, including the adoption and
approval of the Purchase Agreement, the consummation of the Transaction and the
other matters contemplated by the Purchase Agreement and each recommends that
the holders of the Santa Fe Common Units vote FOR approval of the Santa Fe
Proposal.
 
VOTING AT MEETING; RECORD DATES; QUORUM
 
   
    KMEP.  The KM General Partner has established January 11, 1998, as the
record date for the determination of holders of KMEP Common Units entitled to
notice of and to vote at the KMEP Special Meeting. Only holders of record of
KMEP Common Units at the close of business on such date are entitled to vote at
the KMEP Special Meeting. On January 11, 1998, KMEP had outstanding and entitled
to vote 14,111,200 KMEP Common Units, each of which is entitled to one vote per
KMEP Common Unit. On such date, there were approximately 8,700 beneficial owners
of KMEP Common Units.
    
 
    Holders of a majority of the outstanding KMEP Common Units represented in
person or by proxy will constitute a quorum. Assuming the presence of a quorum,
the affirmative vote of the holders of a majority of the issued and outstanding
KMEP Common Units is required to approve the KMEP Proposal. Because the KMEP
Proposal requires the approval of holders of a majority of the KMEP Common
Units, an abstention or broker non-vote or the failure to return the proxy will
have the same effect as a vote cast against the KMEP Proposal.
 
   
    As of January 15, 1998, the KM General Partner and directors and executive
officers of the KM General Partner and their affiliates beneficially owned
approximately 6.1% of the outstanding KMEP Common Units. Each of the above has
advised KMEP that he, she or it intends to vote or direct the vote of
    
 
                                       48
<PAGE>
   
all KMEP Common Units on which he, she or it has voting control for the approval
of the issuance of KMEP Common Units pursuant to the Purchase Agreement. As of
January 11, 1998, neither Santa Fe, the SF General Partner nor SF Holdings owned
any KMEP Common Units.
    
 
   
    SANTA FE.  The SF General Partner has established January 11, 1998, as the
record date for determination of holders of Santa Fe Common Units entitled to
notice of and to vote at the Santa Fe Special Meeting. Only holders of record of
Santa Fe Common Units (other than the SF General Partner and its affiliates) at
the close of business on such date are entitled to vote at the Santa Fe Special
Meeting. On January 11, 1998, Santa Fe had outstanding and entitled to vote
10,995,400 Santa Fe Common Units, each of which is entitled to one vote per
Santa Fe Common Unit. The 8,152,748 Santa Fe Common Units owned by the SF
General Partner and its affiliates are not entitled to vote at the Santa Fe
Special Meeting. On the record date, there were approximately 13,500 beneficial
owners of Santa Fe Common Units.
    
 
   
    Holders of 66 2/3% of the outstanding Santa Fe Common Units (other than
those owned by the SF General Partner and its affiliates) represented in person
or by proxy will constitute a quorum. Assuming the presence of a quorum, the
affirmative vote of the holders of at least 66 2/3% of the issued and
outstanding Santa Fe Common Units (other than those beneficially owned by the SF
General Partner and its affiliates) is required to approve and adopt the Santa
Fe Proposal. Because the Santa Fe Proposal requires the approval of holders of
at least 66 2/3% of the Santa Fe Common Units (excluding Santa Fe Common Units
beneficially owned by the SF General Partner and its affiliates), an abstention
or broker non-vote or the failure to return the proxy will have the same effect
as a vote cast against the Santa Fe Proposal. As of January 11, 1998, neither
KMEP nor the KM General Partner owned any outstanding Santa Fe Common Units.
    
 
KMEP PROXIES
 
   
    Holders of KMEP Common Units are requested to complete, sign, date and
return promptly the enclosed proxy card in the postage paid envelope provided
for this purpose in order to ensure that their KMEP Common Units are voted.
    
 
   
    KMEP Common Units represented by proxies received by KMEP prior to or at the
KMEP Special Meeting will be voted in accordance with instructions contained
therein. KMEP Common Units represented by proxies which are not returned or
returned unsigned will have the same effect as a vote AGAINST the KMEP Proposal.
KMEP Common Units represented by returned and signed proxies but for which no
instruction is given will be voted FOR the KMEP Proposal.
    
 
   
    A proxy may be revoked at any time prior to the exercise of the authority
granted thereunder. Revocation may be accomplished by the granting of a later
proxy with respect to the same KMEP Common Units, by giving notice thereof to
KMEP in writing or at the KMEP Special Meeting at any time prior to the vote on
the matters to be considered. Presence at the KMEP Special Meeting of a holder
of KMEP Common Units who signed a proxy does not in and of itself revoke the
proxy.
    
 
    The KM General Partner is aware of no matters to be presented at the KMEP
Special Meeting other than those described in this Joint Proxy
Statement/Prospectus. If other matters are properly brought before the KMEP
Special Meeting, it is the intention of the persons named in the proxies to vote
the KMEP Common Units to which such proxies relate in accordance with their
judgment.

Units represented by returned and signed proxies but for which no instruction is
given will be voted FOR the Santa Fe Proposal.
    
 
   
    A proxy may be revoked at any time prior to the exercise of the authority
granted thereunder. Revocation may be accompanied by the granting of a later
proxy with respect to the same Santa Fe Common Units, by giving notice thereof
to Santa Fe in writing or at the Santa Fe Special Meeting at any time prior to
the vote on the matters to be considered. Presence at the Santa Fe Special
Meeting of a holder of Santa Fe Common Units who signed a proxy does not in and
of itself revoke the proxy.
    
 
    The SF General Partner knows of no matter to be presented at the Santa Fe
Special Meeting other than those described in this Joint Proxy
Statement/Prospectus. If other matters are properly brought before the Santa Fe
Special Meeting, it is the intention of the persons named in the proxies to vote
the Santa Fe Common Units to which such proxies relate in accordance with their
judgment.

                                THE TRANSACTION
 
BACKGROUND OF THE TRANSACTION
 
   
    SFC--then the parent company of SF Holdings and the indirect parent of the
SF General Partner-- spun-off its energy and real estate subsidiaries in 1990
and its gold company in 1994, and by 1995 the SF General Partner was its only
non-railroad operating subsidiary. SFC became a wholly-owned subsidiary of BNSF
in September 1995 and merged into a subsidiary of BNSF in January 1998.
    
 
   
    During the summer of 1995 through early 1996, in response to two unsolicited
expressions of interest, discussions were held with two large companies in the
pipeline industry concerning a possible transaction and each company conducted
due diligence reviews of Santa Fe. The discussions with each of these companies
were terminated in the first quarter of 1996 without any agreement regarding a
transaction. Neither company proposed to acquire all of Santa Fe or to acquire
Santa Fe Common Units from unitholders other than from SFC or its subsidiaries.
SFC and, after September 1995, BNSF continued to consider inquiries from time to
time about a possible acquisition of its interest in Santa Fe, including
inquiries from Tampa Pipeline Corporation ("TPC").
    
 
   
    During this period, Santa Fe and BNSF also examined other strategic
opportunities with respect to Santa Fe, including potential growth through the
acquisition of other pipelines. However, Santa Fe and BNSF ultimately determined
not to pursue any of the opportunities examined.
    
 
                                       50

    On April 11, 1997, representatives of Goldman Sachs met with Richard D.
Kinder, Chairman of the Board, William V. Morgan, Vice Chairman of the Board,
and Michael Morgan, Vice President of the KM General Partner to discuss several
potential transactions, including the possible acquisition of Santa Fe.
 
    On May 29, 1997, representatives of Goldman Sachs again met with Mr. Kinder,
William Morgan and Michael Morgan as a follow up to the prior meeting and
discussed Santa Fe's business and partnership structure and tax issues
associated with the VREDs and other matters. Mr. Kinder indicated that KMEP was
interested in exploring further a transaction with Santa Fe and authorized
Goldman Sachs to contact BNSF.
 
    In June 1997, at the request of KMEP, a representative of Goldman Sachs
called Denis E. Springer, Senior Vice President and Chief Financial Officer of
BNSF, and a director of the SF General Partner and SF Holdings, and informed Mr.
Springer that a person was potentially interested in acquiring Santa Fe.
 
    On July 25, 1997, Mr. Kinder, Mr. Morgan and other representatives of the KM
General Partner, representatives of Goldman Sachs, and Irvin Toole, Jr.,
Chairman, President and Chief Executive Officer of the SF General Partner and SF
Holdings, Barry R. Pearl, Senior Vice President, Treasurer and Chief Financial
Officer of the SF General Partner and SF Holdings, along with Mr. Springer met
for the purpose of providing information about Santa Fe to KMEP.
 
    On August 12, representatives of KMEP and Goldman Sachs met with Mr.
Springer and representatives of BNSF and presented an outline of a possible
transaction for consideration. The proposal involved an exchange of KMEP Common
Units for Santa Fe's interest in the SF Operating Partnership at a 20% premium
to market with respect to the Santa Fe Common Units, plus a $56.2 million cash
payment to the SF General Partner for its general partner interest.
 
    Between August 12 and August 28, 1997, representatives of BNSF and KMEP
continued to discuss KMEP's proposal.
 
    On August 28, 1997, KMEP proposed an acquisition of Santa Fe in which (1)
Santa Fe Common Units would be exchanged for KMEP Common Units at an exchange
ratio reflecting a 20% premium to Santa Fe Common Unit holders, (2) $95.2
million in cash or KMEP Common Units would be paid for the general partner
interest in Santa Fe and (3) a substantial breakup fee would be paid to KMEP in
the event the transaction was not consummated after a definitive agreement had
been signed. BNSF informed KMEP at that time that it was opposed to the concept
of a breakup fee.
 
   
    Between August 28 and September 12, 1997, representatives of BNSF and KMEP
continued to negotiate the terms of a possible transaction and KMEP continued to
conduct further due diligence investigations.
    
 
    On September 12, 1997, the Board of Directors of the SF General Partner (the
"SF Board") met and were advised of the KMEP offer and the status of
negotiations. In light of the different consideration to be received by the SF
General Partner in respect of its general partner interest in Santa Fe from that
to be received by holders of the Santa Fe Common Units in the Transaction, and
the possible resulting conflict of interests, the SF Board determined that it
would be appropriate to appoint a special committee of directors deemed
independent of the interests of the SF General Partner to represent the
interests of public holders of the Santa Fe Common Units. The SF Board concluded
that Orval M. Adam, Wilford D. Godbold, Jr. and Michael A. Morphy were
independent and appointed them to the Special Committee, with Mr. Godbold
serving as chairman, to evaluate whether the Transaction was in the best
interest of holders of Santa Fe Common Units (other than the SF General
Partner).
 
   
    The SF Board concluded that Messrs. Adam, Godbold and Morphy were
independent because they were not currently officers or employees of the SF
General Partner, BNSF or their affiliates, they did not have any financial
interest in the SF General Partner (other than as directors) and they did not
have any financial interest in the proposed Transaction, other than as holders
of Santa Fe Common Units.
    
 
                                       51
<PAGE>
   
Mr. Adam retired in 1991 as Senior Vice President and Chief Financial Officer of
SFC. Mr. Morphy was a director of SFC until September 1995.
    
 
    Immediately following the meeting of the SF Board, the Special Committee met
to discuss the retention of legal and financial advisors. The Special Committee
selected Gibson, Dunn & Crutcher LLP ("Gibson, Dunn") as its legal advisor, and
requested that Mr. Godbold immediately contact potential financial advisors.
 
    The Special Committee met again on September 15, 1997. At this meeting, the
Special Committee selected Smith Barney as its financial advisor. Gibson, Dunn
then advised the Special Committee of its fiduciary duties in evaluating the
Transaction.
 
    Following its September 15 meeting, the Special Committee held five
additional meetings with representatives from Gibson, Dunn and Smith Barney
through October 6, 1997. At these meetings, discussions were held on numerous
issues, including the progress of the due diligence activities undertaken by
Gibson, Dunn and Smith Barney, respectively, the progress of the financial and
business analysis undertaken by Smith Barney of Santa Fe, KMEP and the proposed
transaction, and the progress of the negotiations with KMEP regarding the terms
of the proposed transaction and the Purchase Agreement.
 
    Throughout the middle of September and up to and including the time of the
execution of the Purchase Agreement, representatives of the parties, as well as
representatives of the Special Committee, conducted due diligence and discussed
the terms of the proposed transaction.
 
   
    On October 6, 1997, representatives of KMEP and Santa Fe arranged for Mr.
Kinder and William Morgan to meet with the Special Committee, and on October 8,
1997, the Special Committee and its advisors met with Mr. Kinder and William
Morgan and with representatives of Goldman Sachs. The Special Committee
discussed with Messrs. Kinder and Morgan their background and management
experience, their perspective on the proposed transaction, their plans and
projections for the combined entity and their views on potential cost savings
from the combination. The Special Committee also interviewed members of senior
management of Santa Fe to understand their perspective on the proposed
transaction, including their view on the likelihood that the combined Santa
Fe/KMEP entity would be able to achieve synergies and savings. The Special
Committee also inquired of senior management as to the possibility of other
acquirors for Santa Fe. In addition, the Special Committee met with Robert D.
Krebs, the Chairman, President and Chief Executive Officer of BNSF and a
director of the SF General Partner and of SF Holdings, and Mr. Springer to
discuss the history of the negotiations between BNSF and KMEP regarding the
terms of the proposed transaction, including the payment to the SF General
Partner for its general partner interest in Santa Fe. The Special Committee also
inquired about prior attempts by BNSF to dispose of the SF General Partner or
its interest in Santa Fe. Following these meetings, the Special Committee and
its advisors held extended discussions about the proposed terms of the
transaction and the desirability of and likelihood of achieving certain
revisions to the terms.
    
 
   
    By October 7, 1997, KMEP and BNSF had reached a tentative understanding to
pursue a proposal contemplating an exchange ratio of 1.36 and a total purchase
price of $95 million (including the Special Distribution) for the general
partner interest in Santa Fe.
    
 
   
    The Special Committee and its advisors met again on the following day after
a meeting of the full SF Board. At this meeting of the Special Committee,
Gibson, Dunn once again reviewed with the members of the Special Committee their
fiduciary duties in evaluating the proposed transaction and Smith Barney
discussed financial aspects of the proposed transaction. Following an extended
discussion of the proposed terms of the transaction, the Special Committee
instructed Smith Barney to present a set of proposed revised terms for the
proposed transaction to BNSF and KMEP.
    
 
   
    The proposals presented by the Special Committee contemplated (i) an
increase in the Exchange Ratio to 1.42 KMEP Common Units for each Santa Fe
Common Unit, (ii) provision for an adjustment in the Exchange Ratio if the
market price of KMEP Common Units increased or decreased by more than 10% during
the period from the announcement of the transaction to the closing, (iii)
addition of a "collar,"
    
 
                                       52
<PAGE>
   
granting either KMEP or Santa Fe the right to terminate the Purchase Agreement
and abandon the transaction if the market price of KMEP Common Units increased
or decreased by more than 25% during the period from the announcement of the
transaction to the closing, (iv) revision of the Agreement of Limited
Partnership of KMEP to change the allocation of distributions between the
limited partners and the general partner, by requiring a larger distribution to
limited partners before the general partner's incentive distribution would
increase from 30% to 50%, (v) adding to the Purchase Agreement a requirement
that Santa Fe and KMEP agree on a mutually satisfactory arrangement regarding
treatment of the VREDs, (vi) an announcement by KMEP of an increase of at least
10% in its normal quarterly distribution to unitholders, and (vii) a reduction
in the purchase price for the interests of the general partner in Santa Fe of
$10 million, from $95 million to $85 million.
    
 
    During the period from October 9, 1997 through October 14, 1997, the parties
and the Special Committee, through their financial advisor, continued to
negotiate the terms of the Purchase Agreement.
 
    On October 15, 1997, at the KM General Partner's regular third quarter Board
of Directors' meeting, the terms of the proposed transaction were discussed,
including the nature of Santa Fe's business, the benefits of the proposed
transaction for holders of KMEP Common Units, the Santa Fe FERC rate case and
potential for additional regulatory action, and the nature of potential
environmental liabilities. The KM General Partner Board of Directors did not
approve any specific transaction at the meeting.
 
   
    On October 15, 1997, the Special Committee met with Gibson, Dunn and Smith
Barney to review BNSF's and KMEP's responses to the Special Committee's proposed
revisions to the terms of the proposed transaction. Following these discussions,
the Special Committee concluded that Mr. Godbold should negotiate on behalf of
the Special Committee directly with BNSF and KMEP to seek improvements to the
terms of the proposed transaction for the benefit of holders of Santa Fe Common
Units. Mr. Godbold and Smith Barney then again contacted BNSF, KMEP and Goldman
Sachs to further pursue the Special Committee's proposals described above.
    
 
    On October 16, 1997, the Special Committee held a meeting with Gibson, Dunn
and Smith Barney in which Mr. Godbold reported that KMEP and BNSF had agreed to
the following revisions to the terms of the proposed transaction:
 
    - The Exchange Ratio would be increased and fixed at 1.39 KMEP Common Units
      per Santa Fe Common Unit rather than 1.36 based on a formula proposed by
      KMEP;
 
    - A collar would be imposed on the trading values of KMEP Common Units,
      permitting Santa Fe or KMEP to terminate the proposed transaction if
      trading values did not remain within such range so as to protect against a
      significant change in the KMEP Common Unit price;
 
    - A condition would be added to the Purchase Agreement requiring that the
      treatment of the VREDs in the Transaction be resolved in a manner
      acceptable to both Santa Fe and KMEP prior to the mailing of this Joint
      Proxy Statement/Prospectus, so as to reduce the likelihood that the post-
      Transaction trading price of KMEP Common Units would be materially
      adversely affected by sales of large quantities of such KMEP Common Units
      by former VRED holders;
 
    - KMEP would commit to announce publicly its intention to increase its
      quarterly cash distribution to at least $.5625 per KMEP Common Unit,
      effective with the first quarter following the Closing;
 
    - The right of Santa Fe to respond to unsolicited alternative acquisition
      offers and to terminate the Purchase Agreement based on a superior offer
      would be broadened and Santa Fe's obligations upon such a termination of
      the Purchase Agreement would be limited to the reimbursement of a limited
      amount of KMEP's actual transaction expenses; and
 
    - BNSF would agree to reduce the cash sale price of the SF General Partner's
      general partner interest in Santa Fe by $5.0 million, which would be used
      to support the above-described improvement in the Exchange Ratio.
 
                                       53
<PAGE>
    On October 17, 1997, the Board of Directors of the KM General Partner met to
discuss the proposed transaction. In attendance were all of the members of the
Board of Directors, Michael Morgan, Clare Doyle, Vice President and Corporate
Counsel of the KM General Partner, David Dehaemers, Vice President and Chief
Financial Officer of the KM General Partner, and a representative of Bracewell &
Patterson, L.L.P., outside corporate counsel to KMEP and the KM General Partner,
and Goldman Sachs. At this meeting KMEP's counsel and management discussed the
Transaction. Goldman Sachs provided its oral opinion to the Board of Directors
of the KM General Partner to the effect that as of such date the Aggregate
Consideration to be paid by KMEP pursuant to the Purchase Agreement was fair
from a financial point of view to KMEP. After a lengthy discussion, the
Transaction was approved by the Board of Directors of the KM General Partner.
 
   
    On October 17, 1997, the Special Committee held a meeting with Gibson, Dunn
and Smith Barney in which Smith Barney reviewed the proposed terms of the
Transaction and its detailed analysis of the fairness of those terms. Smith
Barney then rendered its oral opinion that the Exchange Ratio was fair, from a
financial point of view, to the holders of Santa Fe Common Units. After a full
discussion of the benefits and risks associated with the Transaction, the
Special Committee concluded, based primarily on the factors identified below
under "--Reasons for the Transaction; Recommendations of the General
Partners--Santa Fe Special Committee," that the Transaction was in the best
interests of the holders of Santa Fe Common Units and that it would recommend
approval of the Transaction to the full SF Board.
    
 
    On October 18, 1997, a meeting of the SF Board was held with representatives
of Smith Barney, Gibson, Dunn and Mayer, Brown & Platt, legal counsel to Santa
Fe, the SF General Partner and BNSF, in attendance. Mr. Godbold reviewed the
deliberations of the Special Committee and reported the Special Committee's
conclusion that the Transaction was in the best interests of the holders of
Santa Fe Common Units and its recommendation to proceed with the Transaction.
Smith Barney reviewed with the SF Board its analysis of the fairness of the
Exchange Ratio to the holders of Santa Fe Common Units. A representative of
Mayer, Brown & Platt reported on the final negotiations with respect to the
definitive Purchase Agreement and reviewed the terms thereof in detail with the
directors. The directors discussed the proposed terms and the outside advisors
responded to questions. At the conclusion of the discussion, the Board of
Directors unanimously accepted the recommendation of the Special Committee and
approved the Transaction, subject to several revisions to the Purchase Agreement
to which KMEP later agreed.
 
    The Purchase Agreement was executed by the parties on October 18, 1997, and
announced on October 20, 1997.

<PAGE>
   
    On October 30, 1997, BNSF received an unsolicited proposal from TPC to
purchase BNSF's indirect interest in Santa Fe (the "First TPC Proposal"). In the
First TPC Proposal, BNSF was offered a higher nominal value for its interest in
Santa Fe than the value to be received by BNSF under the Purchase Agreement.
However, the First TPC Proposal did not contemplate that TPC would acquire any
of the Santa Fe Common Units held by Unit holders other than BNSF or its
subsidiaries. BNSF concluded that the First TPC Proposal is not acceptable to it
and has not responded and does not intend to respond to the First TPC Proposal.
On or about November 4, 1997, a copy of the First TPC Proposal was provided to
the Special Committee for its consideration. The Special Committee, after
consultation with its advisors, observed that the First TPC Proposal did not
articulate a clear or credible alternative which would be likely to be more
beneficial to holders of Santa Fe Common Units (other than BNSF and its
subsidiaries) than the Transaction. In light of the foregoing, and because Santa
Fe had entered into the Purchase Agreement, the Special Committee concluded that
no further action by Santa Fe regarding the First TPC Proposal would be
appropriate. The full text of the First TPC Proposal is reproduced below:

    OCTOBER 30, 1997
    
 
   
                            RE:  SANTA FE PIPELINES
    
 
   
    DEAR PATRICK:
    
 
   
    THE PURPOSE OF THIS LETTER IS TO PRESENT TWO ALTERNATIVE DEALS. ALSO, TO
    ADDRESS THE ISSUE OF THE NEW FERC PROCEEDINGS, AND TO PROVIDE MY
    ANALYSIS OF THE ECONOMICS OF THE KINDER DEAL. INCIDENTALLY, BURLINGTON
    NORTHERN SANTA FE HAS THE LEGAL RIGHT TO REVIEW THIS LETTER TO DETERMINE
    IF A DEAL IS EITHER SUPERIOR OR INFERIOR, BASED ON THE PURCHASE
    AGREEMENT DATED OCTOBER 18, 1997, UNDER ARTICLE 8.1(I) "SUPERIOR
    TRANSACTION".
    
 
   
    BEFORE PRESENTING THE ALTERNATIVES, THE FOLLOWING OUTLINES THE ECONOMICS
    OF OUR HISTORICAL TRANSACTIONS AND THE ESSENCE OF THE KINDER DEAL FOR
    $90.2 MILLION.
    
 
   
    WHEN TAMPA PIPELINE FIRST LOOKED AT THE SANTA FE PIPELINE LIMITED
    PARTNERSHIP IN LATE 1994, A MAJOR DIFFICULTY WAS THE VARIABLE RATE
    EXCHANGE DEBENTURES, "VREDS". THESE DEBENTURES WERE TRADING AT A MARKET
    PREMIUM AND CARRIED AN ADDITIONAL CALL PREMIUM. THIS COMBINED PREMIUM
    PRODUCED A NET LIABILITY RELATIVE TO THE UNDERLYING SECURITY.
    SPECIFICALLY, THE UNITS WERE TRADING AT ABOUT $25 AND THE VREDS AT ABOUT
    20% MARKET PREMIUM. THE SECURED NUMBER OF LIMITED PARTNERSHIP UNITS WAS
    8.148 MILLION AND THEY HAD A MARKET VALUE OF $203.7 MILLION. THE VREDS
    BASED ON PREPAYMENT FACE VALUE OF $218 MILLION HAD A MARKET VALUE OF
    $287.7 MILLION (CALCULATED AT TIMES 1.2 AND INCREASED FOR THE CALL
    PREMIUM FOR AN "OPTIONAL REDEMPTION" OF 10% AS OF AUGUST 15, 1995).
    THUS, THERE WAS ABOUT AN $84 MILLION NET LIABILITY. TAMPA PIPELINE
    PROPOSED TO ASSUME THIS LIABILITY AS PART OF THE PIPELINES AND TO PAY AN
    ADDITIONAL $35 MILLION IN CASH FOR THE GENERAL PARTNERSHIP.
    
 
   
    IN JUNE 1997, THE UNITS WERE TRADING AROUND $40 AND HAD A MARKET VALUE
    OF $325.9 MILLION. THE VREDS WERE TRADING WITH ABOUT 32% MARKET PREMIUM,
    A 8.5% CALL PREMIUM, AND WERE VALUED AROUND $312.2 MILLION. TAMPA
    PIPELINE OFFERED $150 MILLION OVER TIME WITH THE CASH FLOW MATCHING WITH
    YOUR DEFERRED TAXES.
    
 
                                       55
<PAGE>
   
    BASED ON THE SUBSEQUENT NEWS ANNOUNCEMENTS ON SANTA FE, THE PARTNERSHIP
    UNITS ARE TRADING AT A PRICE OF ABOUT $47. THE LIMITED PARTNERSHIP UNITS
    ARE NOW WORTH $382.9 MILLION. THE VREDS, WITH A 32% MARKET PREMIUM AND
    7.75% (ASSUMING A 1998 TENDER) CALL PREMIUM, HAVE A VALUE OF $309.3
    MILLION. THIS POSITIVE DIFFERENCE OF $73.6 MILLION IS IN THE OFFERING.
    
 
   
    REVIEWING KINDER MORGAN, THE THIRD QUARTER NET INCOME WAS $1.3 MILLION
    BEFORE NON-RECURRING GAINS, AND NET INCOME FOR NINE MONTHS YEAR TO DATE
    BEFORE NON-RECURRING ITEMS WAS $7.5 MILLION, AND INCLUDING NON-RECURRING
    GAINS WAS $10.0 MILLION.
    
 
   
    KINDER HAS ABOUT 6.5 MILLION LIMITED PARTNER UNITS. PAYMENT OF QUARTERLY
    DISTRIBUTION (BEFORE THE TWO FOR ONE SPLIT) WAS 63 CENTS, FOR A TOTAL OF
    $4.1 MILLION FOR THE FIRST QUARTER, $1.00 FOR THE SECOND QUARTER FOR
    $6.5 MILLION AND ASSUMING $1.00 FOR THE THIRD QUARTER FOR A FURTHER $6.5
    MILLION OF $17.1 FOR THE THREE QUARTERS. THESE DISTRIBUTIONS ARE BOOKED
    ON A CASH BASIS AS KINDER DECLARES AND PAYS THE DISTRIBUTIONS JUST AFTER
    THE END OF EACH QUARTER.
    
 
   
    KINDER MORGAN WHICH STARTED FEBRUARY 14, 1997, HAS ONLY EIGHT MONTHS OF
    STANDING ALONE MANAGEMENT RESPONSIBILITY SINCE THE ENRON BUYOUT, HAS
    LONG TERM DEBT OF $162 MILLION AS OF MID-YEAR, AND HAS FUNDED THE EXCESS
    SHAREHOLDER DISTRIBUTIONS BY INCREASED BORROWING. KINDER HAS AN
    INCENTIVE PAYMENT TO THE GENERAL PARTNER OF 15%, 25% AND 50%. THIS COULD
    BE THE REASON FOR THE HIGH LEVEL OF DISTRIBUTIONS, WHICH EXCEED THE CASH
    FLOW FROM OPERATIONS.
    
 
   
    THE QUESTION IS GIVEN THAT KINDER HAS ALREADY MONITORIZED ALL IT'S
    ASSETS, WHAT IS THE SOURCE OF THE $90.2 MILLION? THE SIMPLE ANSWER IS
    THAT KINDER PLANS TO "SEEK TO TENDER THE DEBENTURES AT OR ABOVE PAR FOR
    CASH OR CONVERT THE UNITS INTO COMMON EQUITY UNITS" (MOOD'S PRESS
    RELEASE OF OCTOBER 23, 1997). ALSO I NOTE THAT THE KINDER DEAL IS
    SUBJECT TO THE PURCHASE AGREEMENT, PARAGRAPH 8.1 (L) A "MUTUALLY
    SATISFACTORY PLAN FOR ADDRESSING THE ISSUES ASSOCIATED WITH THE
    EXCHANGEABILITY OF THE VREDS".
    
 
   
    THE NEXT QUESTION IS WHY DOES BURLINGTON NORTHERN SANTA FE NEED KINDER
    OR IN FACT NEED TAMPA PIPELINE TO PROVIDE SUCH A FINANCIAL RESTRUCTURE,
    WHEN YOU HAVE ONE THE TOP INVESTMENT BANK REPRESENTING YOU? I SEE THAT
    YOU HAVE TWO ADDITIONAL ALTERNATIVES:
    
 
   
           (1) STAND ALONE - BURLINGTON NORTHERN SANTA FE PLAN,
    
 
   
           (2) TAMPA PIPELINE PLAN.
    
 
   
    STAND ALONE - BURLINGTON NORTHERN SANTA FE PLAN
    
 
   
    YOU COULD HAVE GOLDMAN SACHS, SET UP A BRIDGE FINANCING FACILITY, SEEK
    TO TENDER CASH FOR THE VREDS AND OFFER THE RELEASED LIMITED PARTNERSHIP
    UNITS TO THE PUBLIC. IN SUCH A CASE, TAMPA PIPELINE IS STILL WILLING TO
    OFFER YOU A $35 MILLION CASH FOR THE RESIDUAL GENERAL PARTNER INTEREST.
    WE WOULD KEEP THE LIMITED PARTNERSHIP IN PLACE AND RETAIN ALL YOUR
    MANAGEMENT. OUR STRUCTURE DOES NOT UPSET THE PIPELINE LIMITED
    PARTNERSHIP, AS WE WOULD BE ACQUIRING "HOLDINGS". OUR STRUCTURE WOULD
    SOLVE PART OF THE PENDING FERC PROCEEDINGS AS WE DO NOT HAVE A WEST
    COAST MAJOR OIL COMPANY EXPOSURE, AND OUR STRUCTURE WOULD NOT CREATE A
    "CHANGED CIRCUMSTANCES."
    
 
   
    EVEN FACTORING IN SOME MARKET RISK, THE VALUE OF THIS TRANSACTION IS
    GREATER THAN THE KINDER DEAL.
    
 
   
    TAMPA PIPELINE PLAN
    
 
   
    TAMPA PIPELINE WOULD BE WILLING TO COMPLETE THE ABOVE FINANCIAL
    RESTRUCTURE IN OUR NAME, BY LIQUIDATING ON A TIMELY BASIS THE VREDS WITH
    ALL THE FUNDS GOING TO YOU, AND ACQUIRING HOLDINGS FOR $35 MILLION CASH.
    ALSO, WE WOULD BE WILLING TO OFFER YOU A FLOOR PRICE TO REMOVE YOUR
    MARKET RISK OF THIS TRANSACTION, AND TO MAKE SURE THAT WE HAVE A GREATER
    VALUE THAN THE KINDER DEAL. THE AMOUNT AND TERMS OF SUCH A FLOOR PRICE
    WOULD HAVE TO BE NEGOTIATED. THE LIMITED PARTNERSHIP AND ALL YOUR
    MANAGEMENT WILL STAY IN PLACE.

    ALTERNATIVELY, WE ARE STILL WILLING TO PURSUE OUR JUNE 1997 PROPOSAL
    WHERE, TAMPA PIPELINE PROPOSED A $150 MILLION PRICE STRUCTURED WITH THE
    CASH PAYMENTS OVER TIME MATCHING YOUR DEFERRAL OF TAX LIABILITIES, ALONG
    WITH TAMPA PIPELINE STANDING IN FRONT OF YOU ON THE $130 MILLION
    INTER-COMPANY LOAN DUE FROM BURLINGTON NORTHERN TO THE PIPELINES. WE
    WILL KEEP THE LIMITED PARTNERSHIP AND VREDS IN PLACE UNTIL THE TIME WHEN
    THE PREMIUM FALLS AND THEY CAN BE LIQUIDATED, AND WE WILL RETAIN ALL OF
    YOUR MANAGEMENT. ALL THE SECURITY OF SANTA FE PIPELINE HOLDINGS WOULD BE
    PLEDGED TO YOU WITH ALL THE EXCESS CASH GOING TO YOU UNTIL YOU ARE PAID.
    
 
   
    THE ABOVE PROPOSALS ARE SUBJECT TO DOCUMENTATION ACCEPTABLE TO ALL
    PARTIES.
    
 
   
    FEDERAL ENERGY REGULATORY COMMISSION
    
 
   
    WE ARE AWARE OF THE FERC PROCEEDINGS ANNOUNCEMENT OF OCTOBER 28, 1997,
    AND WE CAN REPRESENT TO YOU THAT TAMPA PIPELINE HAS NO CONFLICT WITH
    ARCO PRODUCTS COMPANY, TEXACO REFINING AND MARKETING INC., AND MOBIL OIL
    CORPORATION RELATED TO WEST COAST OPERATIONS, AND BASED ON OUR PURCHASE
    STRUCTURE WE BELIEVE THAT OUR TRANSACTION WOULD NOT BE REFERRED TO AS A
    "CHANGED CIRCUMSTANCE". THE LOSS OF YOUR GRANDFATHER STATUS WOULD
    MATERIALLY IMPACT THE PIPELINES.
    
 
   
    IN SUMMARY, I BELIEVE THAT TAMPA PIPELINE CAN DELIVER A PROPOSAL WITH A
    HIGHER TRANSACTION VALUE THAN KINDER. I HAVE SOME 30 YEARS OF MANAGEMENT
    EXPERIENCE. THE LAST ELEVEN YEARS I HAVE BEEN STANDING ON THE FRONT LINE
    AND HAVE A PROVEN TRACK RECORD OF PAYING DEBT AND MAKING DEALS WORK.
    THROUGH TAMPA PIPELINE, I AM ALSO THE GENERAL PARTNER OF THREE LIMITED
    PARTNERSHIP, TWO DATING BACK TO THE EARLY 1980'S.
    
 
   
    I REQUEST THE OPPORTUNITY TO DISCUSS THIS LETTER WITH YOU IN PERSON, AND
    WILL BE PLEASE TO MEET WITH YOU AT YOUR OFFICES.

    On December 29 and December 31, 1997, an attorney representing an unnamed
party attempted to reach Mayer, Brown & Platt, counsel for Santa Fe, regarding
an unspecified proposal involving Santa Fe. Mayer, Brown & Platt promptly
informed KMEP and the Special Committee of these contacts, but did not return
the telephone calls.
    
 
   
    On January 5, 1998, this attorney again contacted Mayer, Brown & Platt,
identified his client as TPC and stated that TPC intended to present another
proposal to acquire the general partner interest in Santa Fe at a price in
excess of that proposed in the First TPC Proposal and that the new proposal also
would not contemplate any acquisition of Santa Fe Common Units from Unit holders
other than BNSF or its subsidiaries. Mayer, Brown & Platt promptly informed
BNSF, KMEP and the Special Committee of this telephone call.
    
 
   
    On January 6, 1997, Santa Fe, BNSF and counsel to the Special Committee
received another unsolicited proposal from TPC to purchase BNSF's indirect
interest in Santa Fe (the "Second TPC Proposal"). In the Second TPC Proposal,
BNSF was offered $90.2 million for its interest in Santa Fe and TPC proposed to
fund a $0.25 increase in the quarterly distribution to holders of SF Common
Units for two quarters through a $10.0 million contribution to Santa Fe. After
the second quarter, the Second TPC Proposal contemplated that TPC would endeavor
to maintain the increased level of distributions through growth and cost
savings. Like the First TPC Proposal, the Second TPC Proposal did not
contemplate that TPC would acquire any of the Santa Fe Common Units held by Unit
holders other than BNSF or its subsidiaries. BNSF concluded that the Second TPC
Proposal is not acceptable to it and has not responded
    
 
                                       57
<PAGE>
   
and does not intend to respond to the Second TPC Proposal. The Special
Committee, after consultation with its advisors, concluded that the Second TPC
Proposal provided more clarity and credibility than the First TPC Proposal, but
that it did not, standing alone, provide a basis for the Special Committee to
conclude that it presented an alternative that was likely to be more beneficial
than the Transaction to holders of Santa Fe Common Units (other than BNSF and
its subsidiaries). However, the Special Committee determined, after consultation
with and based on the advice of its counsel, that the Special Committee's
fiduciary duties required it to seek further information regarding the Second
TPC Proposal. Accordingly, consistent with the Purchase Agreement, the Special
Committee asked Smith Barney to seek additional information from TPC relating to
its proposal, including a description of TPC's existing operations and
ownership, copies of TPC's audited financial statements, TPC's financial
projections and business plans providing the basis for the Second TPC Proposal,
details regarding financing sources for the Second TPC Proposal and biographies
of the principals of TPC. As of the date of mailing of this Joint Proxy
Statement/Prospectus, the Special Committee has not received a response to this
request. Unless TPC is able to satisfy the Special Committee that the Second TPC
Proposal is likely to provide a transaction more beneficial than the Transaction
to holders of Santa Fe Common Units, the Special Committee will continue to
prefer the Transaction over the Second TPC Proposal. The full text of the Second
TPC Proposal is reproduced below:

    JANUARY 6, 1998
    
 
   
                            RE:  SANTA FE PIPELINES
    
 
   
    DEAR MR. TOOLE:
    
 
   
    THIS LETTER IS INTENDED TO EXPRESS A PROPOSAL BY TAMPA PIPELINE
    CORPORATION TO PURCHASE THE GENERAL PARTNERSHIP OWNERSHIP INTERESTS IN
    SANTA FE PIPELINES. THIS PROPOSAL IS BEING MADE ON AN UNSOLICITED BASIS
    IN ACCORDANCE WITH SECTION 5.10 OF THAT CERTAIN PURCHASE AGREEMENT,
    DATED OCTOBER 18, 1997 (THE "PURCHASE AGREEMENT"), AMONG KINDER MORGAN
    ENERGY PARTNERS, L.P., KINDER MORGAN G.P., INC., SANTA FE PACIFIC
    PIPELINE PARTNERS, L.P., SANTA FE PACIFIC PIPELINE, INC. AND SFP
    PIPELINE HOLDINGS, INC.
    
 
   
    TAMPA PIPELINE SEEKS TO PURCHASE FROM SANTA FE PACIFIC PIPELINES INC.
    (THE "SF GENERAL PARTNER"): (I) THE 1.0% GENERAL PARTNER INTEREST IN
    SANTA FE PACIFIC PIPELINE PARTNERS, L.P. (THE "TRADING PARTNERSHIP"),
    AND (II) THE 1.0101% GENERAL PARTNER INTEREST IN SFPP, L.P. (THE
    "OPERATING PARTNERSHIP"), FOR THE AGGREGATE PURCHASE PRICE OF $100.2
    MILLION PAYABLE IN CASH, WITH $90.2 MILLION FOR THE BENEFIT OF
    BURLINGTON NORTHERN SANTA FE CORPORATION AND $10.0 MILLION AS A SPECIAL
    DISTRIBUTION FOR THE BENEFIT OF THE SANTA FE PACIFIC PIPELINE LIMITED
    PARTNERS.
    
 
   
    TAMPA PIPELINE CORPORATION IS WILLING TO COMPLETE A SIMILAR STRUCTURE
    FOR THE TREATMENT OF THE VRED'S ISSUED BY SFP PIPELINES HOLDINGS, INC.,
    ("HOLDINGS"), AND THE 8,148,130 COMMON UNITS OF THE TRADING PARTNERSHIP
    HELD BY THE SF GENERAL PARTNER, AS IN THE PURCHASE AGREEMENT.
    
 
   
    WE ARE CONFIDENT THAT TAMPA PIPELINE CAN PROVIDE GREATER LONG TERM VALUE
    TO THE UNIT HOLDERS OF SANTA FE PIPELINE AND TO THE HOLDERS OF
    BURLINGTON NORTHERN SANTA FE CORPORATION THAN THE KINDER MORGAN
    TRANSACTION. THE FOLLOWING PRESENTS THE KEY POINTS OF WHY TAMPA PIPELINE
    BELIEVES THAT THIS IS A SUPERIOR TRANSACTION.
    
 
                                       58
<PAGE>
   
    BENEFITS TO SHAREHOLDERS OF BURLINGTON NORTHERN SANTA FE CORPORATION.
    
 
   
    FROM BURLINGTON NORTHERN SANTA FE CORPORATION'S STANDPOINT, THE TAMPA
    PIPELINE TRANSACTION MATCHES THE KINDER MORGAN TRANSACTION OF $90.2
    MILLION CASH. THE MATERIAL BENEFIT IS THAT TAMPA PIPELINE LEAVES THE
    STRUCTURE OF SANTA FE PARTNERSHIP UNCHANGED AND CONSEQUENTLY REMOVES THE
    SIGNIFICANT RISK OF LITIGATION AGAINST BURLINGTON NORTHERN AND THE
    SPECIAL COMMITTEE RELATED TO A NUMBER OF ISSUES OF THE KINDER DEAL.
    
 
   
    BENEFITS TO UNIT HOLDERS OF SANTA FE PIPELINE LP
    
 
   
    WE BELIEVE THAT THE VALUE OF THE KINDER MORGAN TRANSACTION AT A 1.39
    EXCHANGE RATIO SUBJECTS THE SANTA FE LIMITED PARTNERS TO UNNECESSARY
    DILUTION AND EROSION OF THEIR LONG TERM VALUE.
    
 
   
    TAMPA PIPELINE WILL MAINTAIN THE LEGAL STRUCTURE OF THE SANTA FE
    PARTNERSHIP UNCHANGED AS A STAND ALONE ENTITY. NO SANTA FE PIPELINE
    ASSETS WOULD BE MERGED OR COMBINED WITH TAMPA'S EXISTING OPERATIONS.
    THUS, THE EXISTING SANTA FE LIMITED PARTNERS WOULD NOT SUFFER DILUTION
    RESULTING FROM THE COMBINED OPERATIONS.
    
 
   
    TAMPA PIPELINE IS PLANNING TO MAINTAIN AND INCREASE OVER TIME THE SANTA
    FE DISTRIBUTION BASED ON GROWTH AND COST SAVINGS. TO ACHIEVE THIS LEVEL,
    TAMPA PIPELINE WILL INJECT INTO SANTA FE $10 MILLION IN CASH BEING
    SUFFICIENT TO IMMEDIATELY FUND THE INCREASE THE DISTRIBUTION FROM $0.75
    PER QUARTER TO $1.00 PER QUARTER FOR THE INITIAL TWO QUARTERS.
    THEREAFTER, TAMPA PIPELINE PLANS TO MAINTAIN THIS LEVEL OF DISTRIBUTIONS
    THROUGH THE GROWTH AND COST SAVINGS. THIS TARGETED INCREASE IN
    DISTRIBUTIONS WILL BE $20 MILLION PER YEAR. AT THE CURRENT MULTIPLES FOR
    SANTA FE OF ABOUT 15, THIS PLACES THE UNIT PRICE PROJECTED IN A RANGE OF
    $60 TO $65.
    
 
   
    ON THE DOWNSIDE, TAMPA ESTIMATES BASED ON THE TRADING HISTORY OF SANTA
    FE, THAT SANTA FE HAS A SMALL DOWNSIDE RISK FROM ITS CURRENT LEVEL OF
    $45. IN COMPARISON, WE BELIEVE THAT COMBINING SANTA FE WITH KINDER WHICH
    IS CURRENTLY CARRYING A MULTIPLE OF OVER 35, CREATES A SIGNIFICANT
    DOWNSIDE HIGH RISK SITUATION. IF AT ANY POINT KINDER DOES NOT HAVE
    EARNINGS OR A NEW STORY, THEN A MATERIAL DOWNSIDE ADJUSTMENT IN THE
    VALUE OF THE KINDER UNITS COULD OCCUR.
    
 
   
    TAMPA PIPELINE HAS A PROVEN TRACK RECORD OF 12 YEARS OF STABILIZED
    PIPELINE MANAGEMENT. TAMPA PIPELINE'S RECORD IS SHOWN IN ITS ANNUAL
    AUDITED FINANCIAL STATEMENTS, COMBINED WITH THE HANDS ON SUCCESS OF
    REBUILDING AND EXPANDING CERTAIN PIPELINES, THE BUILDING OF PUMP AND
    BOOSTER STATIONS, AND THE EXPANSION INTO ILLINOIS AND TEXAS. TAMPA
    PIPELINE WILL IMMEDIATELY WORK WITH THE SANTA FE ENGINEERS TO IMPLEMENT
    PLANS FOR SANTA FE TO EXPAND AND TO INCREASE THE EARNINGS.
    
 
   
    THE LEGAL STRUCUTURE OF SANTA FE PARTNERSHIP WILL BE LEFT UNCHANGED, AND
    THEREFORE ALL BENEFITS DERIVED FROM TAMPA'S EXPERIENCE AND COST SAVINGS
    WILL GO TO UNIT HOLDERS. IN CONTRAST KINDER HAS A PROBLEM BEING THAT THE
    EARNINGS FROM THE OLD KINDER ARE BELOW ITS DISTRIBUTION RATE, AND
    CONSEQUENTLY THE MAJORITY OF ANY DISTRIBUTION INCREASE WOULD GO TO THE
    OLD KINDER UNIT HOLDERS TO THE DETRIMENT OF THE SANTA FE LIMITED
    PARTNERS.

    BASED ON THE FINANCIAL NUMBERS AS CURRENTLY REPORTED BY KINDER, THE
    SANTA FE UNIT HOLDERS WILL BE SUBSIDIZING KINDER HOLDERS BY $12.1
    MILLION ($16.8 MILLION - $4.7 MILLION), PER YEAR, AND THE FORMER SANTA
    FE UNIT HOLDERS COULD ARGUE THAT THEY HAVE BEEN DAMAGED BY THIS AMOUNT
    PER YEAR. WE BELIEVE TO
    
 
                                       59
<PAGE>
   
    REMOVE THIS RISK ALONG WITH OTHER RISKS OF THE KINDER DEAL IS A
    SIGNIFICANT BENEFIT TO BURLINGTON NORTHERN SANTA FE.
    
 
   
    WE ALSO BELIEVE THAT THERE IS AN ADDITIONAL MATERIAL LONG TERM BENEFIT
    FOR THE SANTA FE LIMITED PARTNERS IN MAINTAINING THE CURRENT SANTA FE
    STRUCTURE. THE UPPER END OF THE INCENTIVE DISTRIBUTION FOR SANTA FE IS
    28%, WHEREAS KINDER MORGAN HAS AN INCENTIVE DISTRIBUTION OF 50%. (SEE
    10K, 1996, ITEM 13). IN THE KINDER TRANSACTION, THE FORMER SANTA FE UNIT
    HOLDERS WILL BECOME SUBJECT TO THE 50% INCENTIVE DISTRIBUTION WHICH
    CAUSES FURTHER DILUTION.
    
 
   
    TAMPA PIPELINE BELIEVES THAT THE APPROVALS NECESSARY TO TRANSFER THE
    GENERAL PARTNER INTERESTS IS FAR MORE NARROW AS COMPARED TO THE KINDER
    MORGAN DEAL WITH THE TERMINATION OF THE PARTNERSHIP. ALSO, THAT THE
    STRUCTURE OF LEAVING THE PARTNERSHIP IN PLACE SHOULD DISPOSE OF THE PART
    OF THE FERC TARIFF APPEAL DEALING WITH THE KINDER "CHANGED
    CIRCUMSTANCES".
    
 
   
    IN PREPARATION TO SUBMIT THIS PROPOSAL, TAMPA PIPELINE HAS SPOKEN WITH
    THE MAJOR US FINANCIAL INSTITUTIONS PROVIDING FINANCING TO PIPELINE
    OPERATIONS. BASED ON THESE CONVERSATIONS, TAMPA PIPELINE IS HIGHLY
    CONFIDENT THAT IT CAN FINANCE THIS TRANSACTION. TAMPA PIPELINE WILL
    PROBABLY CHOOSE TO USE ONE MAJOR INSTITUTION WHICH HAS EXPERIENCE IN
    BOTH PIPELINES AND MASTER LIMITED PARTNERSHIPS.
    
 
   
    WE WOULD LIKE TO MEET WITH THE SPECIAL COMMITTEE TO DISCUSS ANY
    QUESTIONS THEY MAY HAVE REGARDING OUR PROPOSAL. ANY TRANSACTION BETWEEN
    TAMPA PIPELINE AND THE SF GENERAL PARTNER (AND ITS AFFILIATES) WOULD BE
    SUBJECT TO NEGOTIATION AND EXECUTION OF A MUTUALLY SATISFACTORY DEFINITE
    AGREEMENT. IF THE SPECIAL COMMITTEE IS INTERESTING IN PURSUING THIS
    MATTER FURTHER, WE WOULD APPRECIATE THE COURTESY OF A RESPONSE BY THE
    CLOSE OF BUSINESS ON FRIDAY, JANUARY 16, 1998.

     SPECIAL COMMITTEE OF THE BOARD OF DIRECTORS
     OF SF GENERAL PARTNER
    
 
REASONS FOR THE TRANSACTION; RECOMMENDATIONS OF THE GENERAL PARTNERS
 
    KMEP.  The Board of Directors of the KM General Partner believes that the
terms of the Transaction are fair to, and in the best interest of, KMEP and its
holders of KMEP Common Units. The Board of Directors of the KM General Partner
has unanimously approved the Purchase Agreement, the Transaction, the issuance
of the KMEP Common Units upon consummation of the Transaction and the other
matters contemplated thereby, and recommends that the holders of KMEP Common
Units vote FOR approval of the KMEP Proposal.
 
    The Board of Directors of the KM General Partner believes that the
Transaction is in the best interests of KMEP and holders of KMEP Common Units
for the following reasons:
 
                                       60
<PAGE>
        1.  The Transaction is expected to result in an increase in both per
    unit net income and per unit declared distributions for holders of KMEP
    Common Units;
 
        2.  Significant cost savings are expected to be achieved by combining
    the operations of the two partnerships;
 
        3.  Opportunities to solidify customer relationships and enhance revenue
    growth are expected to be improved as a result of the Transaction;
 
        4.  The Transaction is expected to increase the number of attractive
    acquisition opportunities available to KMEP in the future; and
 
        5.  The financial condition of KMEP are expected to be enhanced as a
    result of the Transaction, thereby facilitating the funding of new growth
    initiatives.
 
    In reaching these conclusions, the Board of Directors of the KM General
Partner considered among other things, (a) the respective areas of operating
activity of KMEP and Santa Fe, (b) expected operating and financial
characteristics of a combined entity, and potential synergies associated with
the combination, (c) the experience and performance of Santa Fe management, (d)
the capital structure and financial performance of Santa Fe, (e) current
conditions in the acquisition market for liquids pipelines, and (f) the October
17, 1997 oral opinion of Goldman Sachs to the effect that, as of such date, the
Aggregate Consideration to be paid by KMEP pursuant to the Purchase Agreement
was fair from a financial point of view to KMEP.
 
   
    SANTA FE.  The Board of Directors of the SF General Partner believes that
the terms of the Transaction are in the best interests of the holders of Santa
Fe Common Units. The Board of Directors of the SF General Partner, acting on the
unanimous recommendation of the Special Committee, has unanimously approved the
Purchase Agreement, the Transaction and the other matters contemplated thereby,
and recommends that holders of Santa Fe Common Units vote FOR approval of the
Santa Fe Proposal.
    
 
    The Board of Directors of the SF General Partner believes that the
Transaction is in the best interests of the holders of Santa Fe Common Units for
the following principal reasons:
 
        1.  The Exchange Ratio provides the holders of the Santa Fe Common Units
    with a significant premium over the market price of their Santa Fe Common
    Units prior to the announcement of the Transaction;
 
   
        2.  The Transaction is expected to result in an increased quarterly
    distribution to holders of Santa Fe Common Units who become holders of KMEP
    Common Units;
    
 
   
        3.  As the holders of KMEP Common Units, the holders of Santa Fe Common
    Units will continue to hold an equity security that will entitle them to
    participate in the future of a combined business committed to growth;
    
 
   
        4.  As holders of KMEP Common Units, the holders of Santa Fe Common
    Units will hold an investment in a larger and more broadly diversified
    business;
    
 
   
        5.  Significant cost savings are expected to be achieved by combining
    the operations of the two partnerships;
    
 
   
        6.  The management of KMEP has demonstrated an intention to aggressively
    seek appropriate opportunities to grow and to increase the total return to
    KMEP Common Unit holders; and
    
 
   
        7.  Given the reputation of KMEP and its management for aggressive
    growth, KMEP Common Units present a potential for trading at higher
    multiples of cash flow than Santa Fe Common Units, as well as a greater
    potential for appreciation in price.
    
 
                                       61
<PAGE>
    In reaching these conclusions, the Board of Directors of SF General Partner
considered, among other things, (a) the recommendation of the Special Committee,
and the factors considered by the Special Committee, as described below, (b) the
historical operations and results of Santa Fe and KMEP, (c) the expected
operating and financial characteristics of the combined entity, and potential
synergies associated with the combination, (d) the terms of the Transaction,
including without limitation the premium afforded to holders of Santa Fe Common
Units, and the fact that holders of Santa Fe Common Units would continue to hold
a significant equity interest in the combined enterprise, (e) the background and
experience of the management of KMEP, and the announced commitment of KMEP to
seek continued growth, and (f) the opinion of Smith Barney, rendered to the
Special Committee, to the effect that as of the date thereof the Exchange Ratio
was fair, from a financial point of view, to the holders of Santa Fe Common
Units.
 
   
    Although the SF General Partner has a base economic interest in Santa Fe
(including its interest in the SF Operating Partnership) of only two percent
(which will be reduced to 0.5%, with no right to incentive distributions, as a
result of the Transaction), the Santa Fe Partnership Agreement provides for
additional incentive distributions to the SF General Partner under certain
circumstances. Santa Fe believes that, when these rights of the SF General
Partner are taken into account, the amount that the SF General Partner will
receive in the Transaction is fair to the holders of Santa Fe Common Units,
despite the fact that such amount substantially exceeds 1.5 percent of the total
consideration to be received by the SF General Partner and the holders of SF
Common Units in the Transaction.
    
 
   
    For example, under Sections 5.2 and 14.3 of the Santa Fe Partnership
Agreement, which provide for the distribution of cash following a "Terminating
Capital Event," the SF General Partner is entitled to receive various
percentages of Santa Fe's available cash, increasing to a maximum of 29%
(excluding distributions with respect to its interest in the SF Operating
Partnership), after certain threshold amounts have been distributed to limited
partners. The sale of Santa Fe's interest in the SF Operating Partnership in the
course of a liquidation of Santa Fe would constitute a Terminating Capital
Event. If the formula set forth in the Santa Fe Partnership Agreement applicable
to Terminating Capital Events were applied to a transaction value of $1 billion,
the SF General Partner would be entitled to receive approximately $178.9 million
for its interest in Santa Fe, while retaining its 1% interest in the SF
Operating Partnership. The $84.4 million actually to be received by the SF
General Partner for the sale of its interest in Santa Fe pursuant to the
Transaction represents a significant discount to the amount that would have been
payable if the liquidation formula in the Santa Fe Partnership Agreement had
been applied. See "The Transaction--Opinions of Financial Advisors--Santa
Fe--Analysis of the SF General Partner."
    
 
   
    Similarly, under Section 5.5 of the Santa Fe Partnership Agreement, which
provides for the distribution of cash from operations, the SF General Partner is
entitled to receive various percentages of available cash, increasing to an
aggregate of 30% (taking into account distributions with respect to the SF
Operating Partnership), after certain threshold amounts have been distributed to
limited partners. A discounted cash flow analysis performed with respect to the
amounts projected (based on operating projections by the SF General Partner) to
be available for distribution for the five fiscal years ended December 31, 2002
(using discount rates of 10.0%, 12.0% and 14.0% and terminal yields of 6.0%,
7.0% and 8.0%), results in an implied valuation for its entire interest, in both
Santa Fe and the SF Operating Partnership, ranging from $118.9 million to $176.2
million, with a midpoint of $147.6 million. Even after taking into account the
fact that the SF General Partner will retain a 0.5% interest (which will not
include a right to receive incentive distributions) in the SF Operating
Partnership following the Transaction, the $90.2 million (including the amount
of the Special Distribution) actually to be received by the SF General Partner
pursuant to the Transaction represents a discount to this valuation. See "The
Transaction--Opinions of Financial Advisors--Santa Fe--Analysis of the SF
General Partner."
    
 
    SANTA FE SPECIAL COMMITTEE.  On October 17, 1997, the Special Committee
unanimously determined that the Transaction was in the best interests of the
holders of the Santa Fe Common Units (other than the SF General Partner, whose
interests were represented by its sole stockholder, BNSF) and recommended
 
                                       62
<PAGE>
   
the approval of the Transaction by the Board of Directors of the SF General
Partner and by the holders of the Santa Fe Common Units. In reaching this
conclusion, the Special Committee considered the benefits offered by the
Transaction and weighed them against the risks associated with the Transaction.
See "Risk Factors." While the Special Committee did not consider the risks
associated with the Transaction to be insubstantial, it ultimately concluded
that these risks were outweighed by the potential benefits of the Transaction to
the holders of Santa Fe Common Units. In reaching this determination, the
Special Committee relied, among other things, on the accuracy of the
representations and warranties of KMEP and Santa Fe made in the Purchase
Agreement, the opinions and views of officers of, and outside advisors to, Santa
Fe and KMEP and the advice of the Special Committee's financial and legal
advisors.
    
 
   
    The factors considered by the Special Committee reaching its decision
included, among other things, the following: (a) the viability, and value to the
holders of the Santa Fe Common Units, of preserving Santa Fe as an independent
company, including the possible effects of the Santa Fe FERC proceedings, (b)
the condition, business and prospects of KMEP, including the reputation and
experience of the management of KMEP, (c) possible alternative acquirors for
Santa Fe, (d) the value of the general partner interest of the SF General
Partner in Santa Fe, (e) the value of the combined businesses of Santa Fe and
KMEP to the holders of the Santa Fe Common Units, (f) the value of the premium
being offered to the holders of the Santa Fe Common Units in the Exchange Ratio
of the Transaction, (g) the future projections of cash available for
distributions to the holders of the publicly traded Santa Fe Common Units from
Santa Fe and from the combined operations of Santa Fe and KMEP, (h) the impact
of the potential overhang on the market for KMEP Common Units following the
Transaction from the KMEP Common Units to be acquired by the current holders of
the VREDs, and (i) the respective terms of the partnership agreements of Santa
Fe and KMEP.
    
 
   
    As a result of the foregoing considerations, the Special Committee's
discussions with the respective managements of SF General Partner, KMEP and
BNSF, the Special Committee's other inquiries and the advice of its legal and
financial advisors, the Special Committee identified the following factors in
support of its recommendation to approve the Transaction: (a) Santa Fe is not a
core part of BNSF's business, as evidenced by BNSF's receptiveness to previous
expressions of interest in the SF General Partner, (b) Santa Fe is known within
its industry to be available for acquisition (this was confirmed by both Santa
Fe management and Smith Barney), and yet there has been a lack of interest in
acquiring Santa Fe, (c) the combination of the businesses of Santa Fe and KMEP
provides substantial synergies and the opportunity to realize significant
post-combination cost savings, (d) the management of KMEP is seasoned and
experienced in the energy transport business and has a solid reputation in the
financial community for delivering financial results, (e) KMEP's reputation as
an aggressive growth-oriented master limited partnership should allow the KMEP
Common Units to trade at a higher multiple of cash flow than the Santa Fe Common
Units, and the KMEP Common Units have demonstrated a higher likelihood of
appreciating in value than the Santa Fe Common Units (I.E., the KMEP Common
Units trade at a significantly lower yield than do the Santa Fe Common Units),
(f) the pendency of the Santa Fe FERC proceedings casts uncertainty over Santa
Fe's future performance and its value to investors as an independent company,
(g) the amount being paid to the SF General Partner for its general partner
interest in Santa Fe is reasonable in comparison to its value, (h) Smith Barney,
financial advisor to the Special Committee, has opined that, as of October 17,
1997, the Exchange Ratio is fair, from a financial point of view, to the holders
of the Santa Fe Common Units, and (i) the Purchase Agreement allows Santa Fe to
entertain other unsolicited acquisition proposals received prior to the Closing
and to terminate the Purchase Agreement upon reimbursement of expenses of up to
$2.5 million if a possible Superior Transaction is more beneficial to the
holders of Santa Fe Common Units than the Transaction.
    
 
   
    On January   , 1998, Smith Barney reaffirmed its earlier opinion to the
Special Committee and the Special Committee reaffirmed its recommendation to
approve the Transaction. For a discussion of the impact of the proposals by TPC
to acquire the SF General Partner on the recommendation of the Special
Committee, see "--Background of the Transaction."

OPINIONS OF FINANCIAL ADVISORS
 
   
    KMEP.  On October 17, 1997, Goldman Sachs delivered its oral opinion to the
Board of Directors of the KM General Partner which it confirmed in writing as of
such date, to the effect that as of the date of such opinion, the Aggregate
Consideration to be paid by KMEP pursuant to the Purchase Agreement is fair from
a financial point of view to KMEP. Goldman Sachs subsequently confirmed its
earlier opinion by delivery of its written opinion dated as of the date hereof.
    
 
   
    THE FULL TEXT OF THE WRITTEN OPINION OF GOLDMAN SACHS DATED AS OF THE DATE
HEREOF, WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED AND LIMITATIONS ON
THE REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS INCLUDED AS ANNEX B IN
THE ANNEX VOLUME ACCOMPANYING AND FORMING A PART OF THIS JOINT PROXY
STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE. HOLDERS OF KMEP
COMMON UNITS ARE URGED TO, AND SHOULD, READ SUCH OPINION IN ITS ENTIRETY.
    
 
   
    In connection with its opinion, Goldman Sachs reviewed, among other things,
(i) this Joint Proxy Statement/Prospectus; (ii) the Purchase Agreement; (iii)
the Annual Reports to holders of KMEP Common Units and Santa Fe Common Units and
Annual Reports on Form 10-K of KMEP and Santa Fe for the five years ended
December 31, 1996; (iv) certain interim reports to holders of KMEP Common Units
and Santa Fe Common Units and Quarterly Reports on Form 10-Q of KMEP and Santa
Fe; (v) certain other communications from KMEP and Santa Fe to their respective
unit holders; (vi) certain internal financial analysis and forecasts for KMEP
and Santa Fe prepared by their respective managements, including certain
financial forecasts for KMEP and Santa Fe giving effect to the Transaction
comptemplated by the Purchase Agreement, prepared by the management of KMEP;
(vii) the Amended and Restated Agreement of Limited Partnership of Santa Fe; and
(viii) the Agreement of Limited Partnership of the SF Operating Partnership.
Goldman Sachs also held discussions with members of the senior managements of
KMEP and Santa Fe regarding strategic rationale for, and the potential benefits
of, the transaction contemplated by the Purchase Agreement and the past and
current business operations, financial condition, and future prospects of their
respective companies. In addition, Goldman Sachs reviewed the reported price and
trading activity for the KMEP Common Units and the Santa Fe Common Units,
compared certain financial and stock market information for KMEP and Santa Fe
with similar information for certain other companies the securities of which are
publicly traded, reviewed the terms of certain recent business combinations and
performed such other studies and analysis as it considered appropriate.
    
 
   
    Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information reviewed by it and assumed such accuracy and
completeness for purposes of its opinion. Goldman Sachs assumed, with the
consent of the KM General Partner, that the financial forecasts for KMEP, after
giving effect to the Transaction, including, without limitation, the projected
cost savings and operating synergies resulting from the combination that
management of KMEP expects to achieve, have been reasonably prepared on a basis
reflecting the best currently available judgments and estimates of the
management of KMEP. With respect to the legal and governmental proceedings
described in this Joint Proxy Statement/Prospectus, Goldman Sachs noted that, as
financial advisors, it was not in a position to evaluate or analyze the extent
or timing of liabilities or potential rate reductions, if any, that may arise
from such proceedings and assumed with the consent of the KM General Partner
that these matters will be resolved in a manner which will not adversely affect
in any material respect the financial forecasts on which Goldman Sachs relied
for purposes of its opinion. In addition, Goldman Sachs did not make an
independent evaluation or appraisal of the assets and liabilities of KMEP or
Santa Fe or any of their respective subsidiaries and Goldman Sachs has not been
furnished with any such evaluation or appraisal. The opinion of Goldman Sachs
referred to herein was provided for the information and assistance of the Board
of Directors of the KM General Partner in connection with its consideration of
the Transaction and does not constitute a recommendation as to how any holder of
KMEP Common Units should vote with respect to the Transaction.

    The following is a summary of certain of the financial analyses used by
Goldman Sachs in connection with providing its oral opinion to the Board of
Directors of the KM General Partner on October 17, 1997. Goldman Sachs utilized
substantially the same type of financial analyses in connection with providing
the written opinion included as Annex B in the Annex Volume accompanying and
forming a part of this Joint Proxy Statement/Prospectus.
    
 
        (i) HISTORICAL EXCHANGE RATIO ANALYSIS. Goldman Sachs reviewed and
    compared the historical trading prices for the KMEP Common Units and the
    Santa Fe Common Units for the one year period ended October 8, 1997. Such
    analysis was used to calculate the ratio of the per unit price of the Santa
    Fe Common Units to the per unit price of the KMEP Common Units (on a split
    adjusted basis). Such analysis indicated implied exchange ratios which
    ranged from 2.86 to 1.03. In addition, such analysis indicated average
    implied exchange ratios of 1.83 for the prior year; 1.37 for the prior six
    months; 1.18 for the prior three months and 1.09 for the prior 20 days.
 
        (ii) SELECTED COMPANIES ANALYSIS.
 
   
        KMEP. Goldman Sachs reviewed and compared certain financial information
    relating to KMEP to corresponding financial information, ratios and public
    market multiples for five publicly traded limited partnerships: Buckeye
    Partners, L.P.; Kaneb Pipe Line Partners, L.P.; Lakehead Pipe Line Partners,
    L.P.; Northern Border Partners, L.P.; and TEPPCO Partners, L.P. (the
    "Selected Companies"). The Selected Companies were chosen because they are
    publicly traded companies with operations that for purposes of analysis may
    be considered similar to KMEP. Goldman Sachs calculated and compared various
    financial multiples and ratios. The multiples of KMEP were calculated using
    a price of $39.00 per KMEP Common Unit, the closing price of the KMEP Common
    Units on the NYSE on October 16, 1997. The multiples and ratios for KMEP
    were based on information provided by independent research by Goldman Sachs
    and the multiples for each of the Selected Companies were based on
    independent research by Goldman Sachs. With respect to the Selected
    Companies, Goldman Sachs considered estimated calendar year 1997 and 1998
    price/ earnings ("P/E") ratios, which ranged from 11.7x to 18.8x for
    estimated calendar year 1997 with a mean of 14.3x and 11.3x to 18.8x for
    estimated calendar year 1998 with a mean of 13.9x compared to 34.6x and
    23.0x, respectively, for KMEP; estimated calendar year 1997 and 1998
    discretionary cash flow per unit, which ranged from $2.85 to $5.65 for
    estimated calendar year 1997 and $2.90 to $5.85 for estimated calendar year
    1998 compared to $2.25 and $3.25, respectively, for KMEP; estimated calendar
    year 1997 and 1998 price/discretionary cash flow ratios, which ranged from
    9.5x to 11.5x for estimated calendar year 1997 with a mean of 10.1x and 9.0x
    to 11.3x for estimated calendar year 1998 with a mean of 9.6x compared to
    17.3x and 12.0x, respectively, for KMEP; estimated calendar year 1997 and
    1998 distributable cash flow per unit, which ranged from $2.50 to $4.60 for
    estimated calendar year 1997 and $2.55 to $5.00 for estimated calendar year
    1998 compared to $1.80 and $2.40, respectively, for KMEP; and estimated
    calendar year 1997 and 1998 distribution coverage ratios, which ranged from
    1.1x to 1.5x for estimated calendar year 1997 with a mean of 1.2x and 1.2x
    to 1.6x for estimated calendar year 1998 with a mean of 1.3x compared to
    0.9x and 1.2x, respectively, for KMEP.
    
 
   
        Santa Fe. Goldman Sachs also reviewed and compared certain financial
    information relating to Santa Fe (the "Standalone Case") and Santa Fe, pro
    forma for an exchange ratio of 1.39 (the "Pro-forma Case") to corresponding
    financial information, ratios and public market multiples for the Selected
    Companies. The Selected Companies were chosen because they are publicly
    traded companies with operations that for purposes of analysis may be
    considered similar to Santa Fe. Goldman Sachs calculated and compared
    various financial multiples and ratios. The multiples of Santa Fe were
    calculated using a price of $41.13 per Santa Fe Common Unit, the closing
    price of the Santa Fe Common Units on the NYSE on October 16, 1997. The
    multiples and ratios for Santa Fe were based on information provided by
    independent research by Goldman Sachs and in the Pro-forma Case were derived
    therefrom based on an exchange ratio of 1.39, and the multiples for each of
    the Selected
    
 
                                       65
<PAGE>
    Companies were based on independent research by Goldman Sachs. With respect
    to the Selected Companies, Goldman Sachs considered estimated Calendar year
    1997 and 1998 P/E ratios, which ranged from 11.7x to 18.8x for estimated
    calendar year 1997 with a mean of 14.3x and 11.3x to 18.8x for estimated
    calendar year 1998 with a mean of 13.9x compared to 10.3x and 10.0x,
    respectively, for Santa Fe in the Standalone Case and 13.6x and 13.2x,
    respectively, in the Pro-forma Case; estimated calendar year 1997 and 1998
    discretionary cash flow per unit, which ranged from $2.85 to $5.65 for
    estimated calendar year 1997 and $2.90 to $5.85 for estimated calendar year
    1998 compared to $5.25 and $5.35, respectively, for Santa Fe in the
    Standalone Case and the Pro-forma Case; estimated calendar year 1997 and
    1998 price/discretionary cash flow ratios, which ranged from 9.5x to 11.5x
    for estimated calendar year 1997 with a mean of 10.1x and 9.0x to 11.3x for
    estimated calendar year 1998 with a mean of 9.6x compared to 7.8x and 7.7x,
    respectively, for Santa Fe in the Standalone Case and 10.3x and 10.1x,
    respectively, in the Pro-forma Case; estimated calendar year 1997 and 1998
    distributable cash flow per unit, which ranged from $2.50 to $4.60 for
    estimated calendar year 1997 and $2.55 to $5.00 for estimated calendar year
    1998 compared to $4.30 and $4.35, respectively, for Santa Fe in the
    Standalone Case and the Pro-forma Case; and estimated calendar year 1997 and
    1998 distribution coverage ratios, which ranged from 1.1x to 1.5x for
    estimated calendar year 1997 with a mean of 1.2x and 1.2x to 1.6x for
    estimated calendar year 1998 with a mean of 1.3x compared to 1.4x and 1.5x,
    respectively, for Santa Fe in the Standalone Case and the Pro-forma Case.
 
       (iii) SELECTED TRANSACTIONS ANALYSIS. Goldman Sachs analyzed certain
    information relating to selected transactions in the midstream gas industry
    since 1994 (the "Selected Transactions"). Such analysis indicated that for
    the Selected Transactions (a) levered aggregate consideration as a multiple
    of latest twelve months ("LTM") earnings before interest, taxes,
    depreciation and amortization ("EBITDA") ranged from 4.4x to 12.2x, as
    compared to 11.3x for the levered aggregate consideration as a multiple of
    LTM EBITDA to be received in the Transaction and (b) equity consideration as
    a multiple of LTM, estimated current year and estimated following year
    discretionary cash flow ranged from 3.0x to 18.1x, 2.6x to 11.4x and 2.6x to
    12.5x, respectively, as compared to 11.1x, 11.0x and 10.2x, respectively,
    for the equity consideration as a multiple of LTM, estimated current year
    and estimated following year discretionary cash flow paid in the
    Transaction.
 
        (iv) PRO FORMA ANALYSIS. Goldman Sachs prepared pro-forma analyses of
    the financial impact of the Transaction. Using distributable cash flow
    estimates for KMEP and Santa Fe prepared by KMEP's management for the years
    1998 through 2002, Goldman Sachs compared the distributable cash flow of
    KMEP Common Units, on a standalone basis, to the distributable cash flow of
    the common units of the combined companies on a pro forma basis. Goldman
    Sachs performed this analysis under the following three scenarios: (a)
    KMEP's management's pro forma base case, (b) the base case adjusted for
    KMEP's management's estimates of incremental integration benefits and (c)
    the base case adjusted for management's estimates of incremental integration
    benefits and KMEP's management's estimates of additional corporate
    development opportunities. Based on such analyses, the proposed transaction
    would be accretive to KMEP Common Unit holders on a distributable cash flow
    per common unit basis in the analysis utilizing the additional corporate
    development opportunities in each of the years for which estimates were
    reviewed, in the analysis utilizing only the incremental integration
    beneficiary in the years 1998 through 2001 and in the base case in the years
    1998 through 2000.
 
        (v) CONTRIBUTION ANALYSIS. Goldman Sachs reviewed certain historical and
    estimated future operating and financial information (including, among other
    things, total assets, net worth, revenues, EBITDA and total distributable
    cash flow) for KMEP, Santa Fe and the pro forma combined entity resulting
    from the Transaction based on financial data provided by the managements of
    KMEP and Santa Fe for each of KMEP and Santa Fe, respectively. This analysis
    indicated that the KMEP Common Unit holders would retain 34.6% of the
    outstanding common equity of the combined companies after the Transaction.
    Goldman Sachs also analyzed the relative contribution of KMEP to
 
                                       66
<PAGE>
    the combined company on a pro forma basis before taking into account any of
    the possible benefits that may be realized following the Transaction based
    on current total assets and net worth and estimated year 1998 with respect
    to revenues, EBITDA and total distributable cash flow, based on financial
    data and on the estimates provided to Goldman Sachs by KMEP and Santa Fe.
    This analysis indicated that KMEP would be contributing 28.9% to total
    assets on a current basis and 31.3% to total net worth on a current basis.
    This analysis also indicated that in 1998 KMEP would be contributing 26.6%
    to estimated combined revenues, 29.8% to estimated combined EBITDA and 31.9%
    to estimated combined total distributable cash flow.
 
   
    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Goldman Sachs' opinion. In arriving at its fairness determination,
Goldman Sachs considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is directly comparable to
KMEP or Santa Fe or the Transaction. The analyses were prepared solely for
purposes of Goldman Sachs providing its opinion to the Board of Directors of the
KM General Partner as to the fairness of the Aggregate Consideration from a
financial point of view and do not purport to be appraisals or necessarily
reflect the prices at which businesses or securities actually may be sold.
Analyses based upon forecasts of future results are not necessarily indicative
of actual future results, which may be significantly more or less favorable than
suggested by such analyses. Because such analyses are inherently subject to
uncertainty, being based upon numerous factors or events beyond the control of
the parties or their respective advisors, none of KMEP, Santa Fe, Goldman Sachs
or any other person assumes responsibility if future results are materially
different from those forecast. As described above, Goldman Sachs' opinion to the
Board of Directors of the KM General Partner was one of many factors taken into
consideration by the Board of Directors of the KM General Partner in making its
determination to approve the Purchase Agreement. The foregoing summary does not
purport to be a complete description of the analysis performed by Goldman Sachs
and is qualified by reference to the written opinion of Goldman Sachs set forth
in Annex B included in the Annex Volume that accompanies and forms a part of
this Joint Proxy Statement/Prospectus.
    
 
   
    Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements,
and valuations for estate, corporate and other purposes. The KM General Partner
selected Goldman Sachs as its financial advisor because it is a nationally
recognized investment banking firm that has substantial experience in
transactions similar to the Transaction. Goldman Sachs is familiar with Santa
Fe, having provided certain investment banking services to Santa Fe from time to
time. Goldman Sachs also has provided investment banking services to BNSF from
time to time, including acting as a managing underwriter of a public offering of
7.250% Debentures due 2097 for BNSF in July 1997, a public offering of 7.290%
Debentures due 2036 of BNSF in May 1996 and a public offering of 6.375% Notes
due 2005 in December 1995. In addition, Goldman Sachs Credit Partners L.P., an
affiliate of Goldman Sachs, will serve as lead arranger of the KMEP Loan
Facility and it is also expected that Goldman Sachs will serve as managing
underwriter of the anticipated offering of KMEP Common Units following the
expiration of the VRED Exchange Offer.
    
 
   
    Goldman Sachs provides a full range of financial, advisory and securities
services and, in the course of its normal trading activities, may from time to
time effect transactions and hold positions in the securities or options on
securities of KMEP and/or Santa Fe for its own account and for the account of
customers. As of the date hereof Goldman Sachs has for its own account a short
position of 40,400 Santa Fe Common Units and a long position of $17,803,000 par
value of VREDS.
    
 
    Pursuant to a letter agreement dated October 15, 1997 (the "Engagement
Letter"), KMEP engaged Goldman Sachs to act as its financial advisor in
connection with the Transaction. Pursuant to the terms of
 
                                       67
<PAGE>
the Engagement Letter, KMEP has agreed to pay Goldman Sachs upon consummation of
the Transaction a transaction fee equal to $7,000,000. Up to $2,000,000 of such
fee may be credited against any underwriting or other fees to be paid by KMEP to
Goldman Sachs in connection with other aspects of the Transaction. KMEP has
agreed to reimburse Goldman Sachs for its reasonable out-of-pocket expenses, and
to indemnify Goldman Sachs against certain liabilities, including certain
liabilities under the federal securities laws.
 
   
    SANTA FE.  The Special Committee retained Smith Barney to act as financial
advisor to the Special Committee in connection with the Transaction. In
connection with its engagement, Smith Barney has delivered to the Special
Committee an oral opinion on October 17, 1997, its written confirming opinion
dated October 18, 1997 and its written reconfirming opinion dated the date
hereof (the "Opinion"), to the effect that, as of such date based upon and
subject to certain matters stated therein, that the exchange of 1.39 KMEP Common
Units for each Santa Fe Common Unit (the "Exchange Ratio") is fair from a
financial point of view to the holders of Santa Fe Common Units. The description
set forth below pertains to Smith Barney's written Opinion.
    
 
    In arriving at its opinion, Smith Barney reviewed the Purchase Agreement and
held discussions with certain senior officers and other representatives and
advisors of the SF General Partner and Santa Fe and certain senior officers and
other representatives and advisors of KMEP concerning the business, operations
and prospects of Santa Fe and KMEP, respectively. Smith Barney examined certain
publicly available business and financial information relating to Santa Fe and
KMEP as well as certain financial forecasts and other financial and operating
data which were provided to or otherwise discussed with Smith Barney by the
respective management of Santa Fe and KMEP, including information relating to
certain strategic implications and operational benefits anticipated to result
from the Transaction. Smith Barney reviewed the financial terms of the
Transaction as set forth in the Purchase Agreement in relation to, among other
things: current and historical market prices, trading volumes and yields of the
Santa Fe Common Units and the KMEP Common Units; historical and projected
earnings and other operating data of Santa Fe and KMEP; and the capitalization
and financial condition of Santa Fe and KMEP. Smith Barney specifically
considered the consideration to be received by the SF General Partner. Smith
Barney also analyzed certain financial, stock market and other publicly
available information relating to the businesses of other companies whose
operations Smith Barney considered relevant. Smith Barney also evaluated the
potential pro forma impact of the Transaction on KMEP. In addition to the
foregoing, Smith Barney conducted such other analyses and examination and
considered such other financial, economic and market criteria as it deemed
appropriate to arrive at its Opinion.
 
   
    In rendering its Opinion, Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with them. With respect to financial forecasts and
other information furnished to or otherwise reviewed by or discussed with Smith
Barney, the managements of Santa Fe and KMEP advised Smith Barney that such
forecasts and other information were reasonably prepared on bases reflecting the
best currently available estimates and judgments of Santa Fe and KMEP as to the
expected future financial performance of Santa Fe and KMEP and the strategic
implications and operational benefits anticipated to result from the
Transaction. Smith Barney further relied on the assurances of management of
Santa Fe and KMEP that they were unaware of any facts that would make the
information or forecasts provided to Smith Barney incomplete or misleading. In
particular, Smith Barney was provided and relied upon a schedule from KMEP of
estimated cost savings that KMEP expects to achieve as a result of the
Transaction. Smith Barney was not engaged to assess the accuracy of the
information provided to it or the reasonableness of the projections or other
forward looking information provided to it. Specifically, with respect to the
legal and regulatory proceedings described in this Joint Proxy
Statement/Prospectus, Smith Barney was not in a position to evaluate the impact
of such proceedings and assumed that these matters will be resolved in a manner
which will not adversely affect in any material respect the financial forecasts
on which Smith Barney relied for purposes of its Opinion. Smith
    
 
                                       68
<PAGE>
Barney has not made or been provided with an independent evaluation or appraisal
of the assets or liabilities (contingent or otherwise) of Santa Fe or KMEP nor
has it made any physical inspection of the properties or assets of Santa Fe or
KMEP. Smith Barney's Opinion relates to the relative values of Santa Fe and
KMEP. Smith Barney did not express any opinion as to what the value of the KMEP
Common Units actually will be when issued to the holders of the Santa Fe Common
Units or the prices at which the KMEP Common Units will trade subsequent to the
Transaction. In addition, Smith Barney has not been asked to nor did they
express an opinion as to the relative merits of the Transaction as compared to
any alternative business strategies that might exist for Santa Fe or the effect
of any other transaction in which Santa Fe might engage. Smith Barney was not
engaged to solicit third-party indications of interest in acquiring all or part
of Santa Fe. Smith Barney's Opinion is necessarily based upon information
available to them, and financial, stock market and other conditions and
circumstances existing and disclosed to Smith Barney, as of the date of its
Opinion.
 
   
    THE FULL TEXT OF THE OPINION WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS
CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN, IS INCLUDED AS ANNEX C IN
THE ANNEX VOLUME THAT ACCOMPANIES AND FORMS A PART OF THIS JOINT PROXY
STATEMENT/PROSPECTUS. HOLDERS OF THE SANTA FE COMMON UNITS ARE URGED TO READ
THIS OPINION CAREFULLY IN ITS ENTIRETY. SMITH BARNEY'S OPINION IS DIRECTED ONLY
TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE EXCHANGE RATIO AND HAS
BEEN PROVIDED FOR THE USE OF THE SPECIAL COMMITTEE IN ITS EVALUATION OF THE
TRANSACTION. IT DOES NOT ADDRESS ANY OTHER ASPECT OF THE TRANSACTION OR ANY
RELATED TRANSACTION AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY HOLDER OF
SANTA FE COMMON UNITS AS TO HOW SUCH HOLDER SHOULD VOTE AT THE SANTA FE SPECIAL
MEETING. THE SUMMARY OF THE OPINION SET FORTH IN THIS JOINT PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF SUCH OPINION.
    
 
    In preparing its Opinion, Smith Barney performed a variety of financial and
comparative analyses. Although the following summary is believed to be
reasonable, it does not purport to be a complete description of the analyses
underlying the Opinion. The preparation of a fairness opinion is a complex
analytic process involving various determinations as to the most appropriate and
relevant methods of financial analyses and the application of those methods to
the particular circumstances and, therefore, such an opinion is not necessarily
susceptible to summary description. In arriving at its Opinion, Smith Barney did
not attribute any particular weight to any analysis or factor considered by it,
but rather made qualitative judgments as to the significance and relevance of
portions of its analyses and various factors. Accordingly, Smith Barney believes
that its analyses must be considered as a whole and focusing on portions of its
analyses and certain factors, without considering all analyses and factors,
could create a misleading or incomplete view of the processes underlying such
analyses and its Opinion. In its analyses, Smith Barney made numerous
assumptions with respect to Santa Fe and KMEP, industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of Santa Fe and KMEP. Further, the estimates
contained in such analyses are not necessarily indicative of actual values or
predictive of future results or values, which may be significantly more or less
favorable than suggested by such analyses. In addition, analyses relating to the
value of the businesses or securities do not purport to be appraisals or to
reflect the prices at which the businesses or securities may actually be sold.
Accordingly, such analyses and estimates are inherently subject to substantial
uncertainty.
 
    REVIEW OF SELECTED COMPANIES.  In performing the analyses described below,
Smith Barney reviewed the operating and trading statistics of a group of seven
selected companies which were classified into two categories: master limited
partnerships which are expected to continue increasing distributions to unit
holders (the "Growth MLPs") and master limited partnerships whose major lines of
business can be classified as pipeline and transportation (the "Pipeline and
Transportation MLPs" and with the Growth MLPs the "Selected Companies"). The
Growth MLPs included: Buckeye Partners, L.P., Lakehead Pipe Line Partners, L.P.,
Leviathan Gas Pipeline Partners, L.P., TEPPCO Partners, L.P. and Plum Creek
Timber Company, L.P. The Pipeline and Transportation MLPs included: Northern
Border Partners, L.P. and Kaneb Pipeline Partners, L.P.

    ANALYSIS OF SANTA FE COMMON UNITS.  Smith Barney performed a discounted cash
flow analysis of the projected free cash flows to the holders of Santa Fe Common
Units, for the five fiscal years ending December 31, 2002. Smith Barney assumed
discount rates of 8.0%, 9.0% and 10.0% and terminal multiples of earnings before
interest, taxes, depreciation and amortization ("EBITDA") in 2002 of 8x, 9x and
10x. The discount rates were based on the cost of capital of Santa Fe and the
terminal value multiples were based on the trading multiples of the Pipeline and
Transportation MLPs.
 
    Smith Barney performed the discounted cash flow analysis on the operating
projections prepared by Santa Fe management. In performing the analysis, Smith
Barney assumed that the SF General Partner received its distributions as
calculated pursuant to the Santa Fe Partnership Agreement and that the SF
General Partner was entitled to its pro rata share of the capitalized terminal
value, which share was determined to be the same percentage that the SF General
Partner would have received of 2002 estimated free cash flows of Santa Fe. This
analysis resulted in an implied valuation range for the Santa Fe Common Units of
$635.1 million ($33.17 per Santa Fe Common Unit) to $864.5 million ($45.15 per
Santa Fe Common Unit). The mid-point of the implied valuation range was then
calculated to be $749.8 million ($39.16 per Santa Fe Common Unit). When the
Exchange Ratio is multiplied by the closing price of KMEP on the last day of
trading prior to the announcement of the Transaction, an implied value is
derived for the consideration to be received by the Santa Fe Common Unit holders
of $54.21 per Santa Fe Common Unit (the "Implied Trading Value"). When the
Implied Trading Value is compared to the mid-point of the implied valuation
range based on the discounted cash flow analysis of $39.16 per Santa Fe Common
Unit, a premium of 38.4% is calculated.
 
   
    ANALYSIS OF KMEP COMMON UNITS.  In order to evaluate the pro forma impact of
the Transaction on KMEP, Smith Barney compiled information from certain
information on estimated cost savings materials that it received from Santa Fe
and KMEP. In analyzing the pro forma impact to KMEP, Smith Barney specifically
reviewed the following: (i) the projected distributions to be received per KMEP
Common Unit, (ii) the percentage of total distributions to be received by the KM
General Partner, and (iii) pro forma financial statements giving effect to the
Transaction.
    
 
   
    Smith Barney performed a discounted cash flow analysis of the projected free
cash flows to the holders of KMEP Common Units after giving pro forma effect to
the Transaction for the five fiscal years ending December 31, 2002. Smith Barney
assumed discount rates of 8.0%, 9.0% and 10.0% and terminal value multiples of
EBITDA in 2002 of 10x, 11x and 12x. The discount rates used were based on the
cost of capital of KMEP and the terminal value multiples were based on the
trading multiples of the Growth MLPs. Smith Barney assumed that after the
Transaction, KMEP would continue to be valued in the market as a Growth MLP.
    
 
   
    In performing this discounted cash flow analysis, Smith Barney used
operating projections prepared by the managements of KMEP and Santa Fe. In
addition, Smith Barney assumed that the KM General Partner received its
distributions as calculated pursuant to the KMEP Partnership Agreement and that
the KM General Partner was entitled to its pro rata share of the capitalized
terminal value, which share was determined to be the same percentage that the KM
General Partner would have received of 2002 estimated free cash flows of KMEP
after giving pro forma effect to the Transaction. These analyses resulted in an
implied pro forma valuation range for the KMEP Common Units of $1,030.5 million
($25.30 per KMEP Common Unit) to $1,353.9 million ($33.24 per KMEP Common Unit).
The mid-point of the implied valuation range was then calculated to be $1,192.2
million ($29.27 per KMEP Common Unit).
    
 
    Smith Barney then multiplied the results derived in the KMEP discounted cash
flow analysis by the Exchange Ratio in order to estimate the value to be
received for each Santa Fe Common Unit. This calculation resulted in a range of
$1,432.4 million ($35.17 per Santa Fe Common Unit) to $1,881.9 million ($46.21
per Santa Fe Common Unit). The mid-point of this range was then calculated to be
$1,657.2 million ($40.69 per Santa Fe Common Unit). When this mid-point of
$40.69 is compared to the mid-point of $39.16 as calculated in "Valuation of
Santa Fe Common Units," a premium of 3.9% is calculated.
 
                                       70

    CONTRIBUTION ANALYSIS.  Assuming consummation of the Transaction, Smith
Barney analyzed the respective contributions of Santa Fe and KMEP to the
estimated revenues, EBITDA, net income, distributable cash flow to be received
by the limited partners, total distributable cash flow and total assets for the
six months ending December 31, 1997 and the fiscal years ending December 31,
1997 through 2002, before giving effect to certain cost savings and other
potential synergies anticipated by the management of KMEP. Smith Barney placed
more importance on the distributable cash flow to the limited partners component
of the contribution analysis than the other components due to the fact that the
distributable cash flow to the limited partners is the most significant
valuation parameter for limited partnership units. Smith Barney then compared
these results to the percentage of KMEP Common Units to be received by the
holders of Santa Fe Common Units in the Transaction. For the six months ending
December 31, 1997 and for the fiscal years ending December 31, 1997, 1998, 1999,
2000, 2001 and 2002, Santa Fe's operations are projected to contribute 66.6%,
71.8%, 63.9%, 62.0%, 65.8%, 64.9%, and 64.0%, respectively, of distributable
cash flow to the limited partners. Based on the Exchange Ratio, holders of Santa
Fe Common Units will receive 65.4% of the Santa Fe Common Units.
    
 
    IMPLIED YIELD VALUATION SUMMARY.  Smith Barney analyzed what the implied
trading values would be for the Santa Fe Common Units and the KMEP Common Units
by assuming a range of trading yields and assuming that the limited partner
distributions are equal to the pro forma available cash. In performing this
analysis, Smith Barney assumed trading yields of 5.0% to 9.0% and applied these
yields to the assumed limited partner distributions of Santa Fe and KMEP
assuming consummation of the Transaction for 1998 and 1999. The range of trading
yields was derived by looking at the trading yields of the Selected Companies.
 
    For illustrative purposes, when using the median trading yield of the
Pipeline and Transportation MLP's of 7.0% and Santa Fe's 1998 and 1999 projected
limited partner distributions of $3.00 per unit, a Santa Fe Common Unit would be
worth $42.86. Using the median trading yield of the Growth MLP's of 6.5% and
KMEP's 1998 limited partner distributions of $2.28 per unit, a KMEP Common Unit
would have an implied value of $35.09 and using KMEP's 1999 projected limited
partner distributions of $2.33 per unit, and the 6.5% median yield, a KMEP
Common Unit would have an implied value of $35.86. Multiplying the implied value
for a KMEP Common Unit by the Exchange Ratio results in an implied value for a
Santa Fe Common Unit of $48.77 in 1998 and $49.85 in 1999. When the 1998 and
1999 implied values for a Santa Fe Common Unit are compared to the trading price
of a Santa Fe Common Unit on the last trading day prior to the announcement of
the Transaction of $41.13, premiums of 18.6% and 21.2% are calculated.
 
    ANALYSIS OF THE SF GENERAL PARTNER.  Smith Barney also analyzed the value of
the SF General Partner. Smith Barney performed a discounted cash flow analysis
of the projected free cash flows to be received by the SF General Partner for
the five fiscal years ending December 31, 2002. Smith Barney assumed discount
rates of 10.0%, 12.0% and 14.0% and terminal yields of 6.0%, 7.0%, and 8.0%. The
discount rates and terminal yields were determined by comparing the risk of
receiving a distribution from the Santa Fe Common Unit holder perspective with
the risk of the SF General Partner receiving its incentive distributions. It was
determined that the SF General Partner's risk profile of receiving all of its
projected distributions is greater than that of a Santa Fe Common Unit holder
and therefore higher discount rates were used in the discounted cash flow
analysis of distributions to the SF General Partner than were used in the
discounted cash flow analysis of distributions to the Santa Fe Common Unit
holders.
 
    Smith Barney performed the discounted cash flow analyses using the operating
projections prepared by Santa Fe management. This analysis resulted in an
implied valuation range for the SF General Partner of $118.9 million to $176.2
million. The mid-point of the implied valuation range was then calculated to be
$147.6 million. When the mid-point of $147.6 million is compared to the $90.2
million that the SF General Partner is receiving in the Transaction, a discount
of (38.9%) is calculated.
 
                                       71
<PAGE>
    Smith Barney also analyzed the value which would be received by the SF
General Partner in the event that Santa Fe was liquidated. In preparing this
analysis, Smith Barney used the liquidation allocations as set forth in the
Santa Fe Partnership Agreement and assumed a range of equity values for Santa Fe
of $700 million to $1,000 million. Smith Barney calculated the value to be
received by the SF General Partner in a liquidation to be within a range of
$91.9 million to $178.9 million, with a mid-point of $135.4 million. When the
mid-point of $135.4 million is compared to the $90.2 million that the SF General
Partner is receiving in the Transaction (which includes the Special
Distribution), a discount of (33.4%) is calculated.
 
    PREMIUM ANALYSIS.  Smith Barney also analyzed the premium to be received by
the Santa Fe Common Unit holders based on the closing market prices of the Santa
Fe Common Units and the KMEP Common Units on October 16, 1997. Based on this
analysis, the premium to be realized by the Santa Fe Common Unit holder was
calculated to be 32%. In addition, Smith Barney also looked at the premium to be
realized based on the average of the high and the low trading prices for each of
the twenty trading days prior to, and including, October 16, 1997. Based on this
analysis, the premium to be realized by the Santa Fe Common Unit holders was
calculated to be 28%.
 
    OTHER MATTERS.  The Santa Fe Partnerships entered into an engagement letter
with Smith Barney on October 6, 1997 pursuant to which the Santa Fe Partnerships
agreed to pay Smith Barney fees of $1.875 million, comprised of a retainer fee
of $400,000, which was payable upon execution of the engagement letter and an
opinion fee of $1.475 million, which was payable upon delivery of Smith Barney's
opinion, dated October 18, 1997. The Santa Fe Partnerships have agreed to
reimburse Smith Barney for its out-of-pocket expenses, including reasonable fees
and disbursements of counsel provided that such fees and expenses of counsel
shall not be in excess of $75,000 in the aggregate without the prior written
consent of Santa Fe. The SF General Partner and the Santa Fe Partnerships have
also agreed, in a separate letter agreement, to indemnify Smith Barney and its
affiliates, their respective directors, officers, agents and employees and each
person, if any, controlling Smith Barney or any of its affiliates against
certain liabilities, including liabilities under federal securities laws and
expenses related to Smith Barney's engagement.
 
    Smith Barney is a nationally recognized investment banking firm and is
regularly engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
bids, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes. Other than
acting as financial advisor in connection with the Transaction (and delivery of
its Opinion), Smith Barney has not previously performed investment banking
services for the SF General Partner or the SF Operating Partnership. In the
ordinary course of business, Smith Barney may, from time to time, buy and sell
securities of KMEP and Santa Fe.
 
CERTAIN PENDING LITIGATION
 
    Four purported Santa Fe Common Unit holder class actions have been filed
arising out of the Transaction. On October 23, 1997, shortly after the
announcement of the Transaction, a purported Santa Fe Common Unit holder class
action was filed in the Court of Chancery of the State of Delaware (RUDERMAN V.
SANTA FE PIPELINE PARTNERS, L.P., C.A. No. 16002NC). Later on the same day
another purported Santa Fe Common Unit holder class action was filed in the
Superior Court of the State of California, County of Orange (VOGEL V. SANTA FE
PIPELINE PARTNERS, L.P., Case No. 785816). On October 24, 1997, a second
purported Santa Fe Common Unit holder class action was filed in the Court of
Chancery of the State of Delaware (BECK V. SANTA FE PIPELINE PARTNERS, L.P.,
C.A. No. 16005). On November 6, 1997, a third purported Santa Fe Common Unit
holder class action was filed in the Court of Chancery of the State of Delaware
(HOCHEISER V. SANTA FE PACIFIC PIPELINE PARTNERS, L.P., C.A. No. 16023NC). The
foregoing causes of action are referred to as the "Unitholder Suits."
 
    The actions name as defendants Santa Fe, the SF General Partner and the
individual members of the SF General Partner Board of Directors. In addition,
VOGEL and RUDERMAN name KMEP as a defendant and
 
                                       72
<PAGE>
   
BECK and HOCHEISER name SF Holdings as a defendant. In general, the actions
variously allege that the individual defendants suffered from a conflict of
interest in the negotiation of the Transaction, that despite this conflict they
did not appoint or retain independent representation for the Santa Fe Common
Unit holders, and that this conflict resulted in an excessive payment to the SF
General Partner. The actions further allege that the defendants breached their
duties of loyalty and due care to the Santa Fe Common Unit holders and that the
defendants failed to fully inform themselves about the value of the Santa Fe
Common Units (including allegedly failing to obtain valid appraisals of the
value of the SF General Partner's interests in Santa Fe, failing to conduct an
auction process or active market check, and failing to examine the fairness of
the Transaction). BECK and VOGEL allege that the terms of the Transaction are
intrinsically unfair and inadequate from the Santa Fe Common Unit holders'
perspective. RUDERMAN alleges that the payment to the SF General Partner
"constitutes an unlawful payoff, kickback, or conversion of Partnership assets."
VOGEL alleges that the defendants allowed the price of the Santa Fe Common Units
to be capped, depriving plaintiffs of the opportunity to realize an increase in
the value of the Santa Fe Common Units. BECK and HOCHEISER allege that the
defendants intended to take advantage of the disparity between the knowledge and
information possessed by the defendants compared to the class by inducing the
Santa Fe Common Unit holders to approve the Transaction based on incomplete or
inadequate information. The three actions filed in Delaware have been
consolidated into one action, now styled IN RE SANTA FE PACIFIC PIPELINE
PARTNERS, L.P. UNITHOLDERS LITIGATION, C.A. No. 16002NC.
    
 
   
    The actions seek certification of a class action on behalf of the Santa Fe
Common Unit holders of Santa Fe. The actions seek preliminary and permanent
injunctions of the Transaction, rescission of the Transaction if it is
consummated, an award of rescissory damages and other damages including
attorneys' fees, an accounting by defendants of any special benefits obtained
from the Transaction, imposition of a constructive trust for any consideration
received by the defendants, and any other relief the court finds appropriate.
    
 
    Defendants believe that all of these lawsuits are without merit and intend
to oppose them vigorously.
 
INTERESTS OF CERTAIN PERSONS IN THE TRANSACTION
 
    OFFICERS AND DIRECTORS OF THE SF GENERAL PARTNER.  The following describes
the interests in the Transaction of the directors and executive officers of the
SF General Partner, other than solely as holders of Santa Fe Common Units.
 
   
    The Transaction will constitute a "change of control" under the employment
agreements for each of the following officers of the SF General Partner: Irvin
Toole, Jr., Chairman, President and Chief Executive Officer, John M. Abboud,
Senior Vice President-Operations and Technical Services, Robert L. Edwards,
Senior Vice President-Business Development, Barry R. Pearl, Senior Vice
President, Treasurer and Chief Financial Officer, R. Gregory Cunningham, Vice
President and General Counsel, and Lyle B. Boarts, Vice President-Human
Resources (the "SF Executive Officers"). As a result of the "change of control,"
the SF Executive Officers will be entitled under the terms of their employment
agreements to receive the following payments and benefits if (i) the SF
Executive Officer is not hired by the KM General Partner and his employment with
the SF General Partner is terminated (including constructive termination) within
24 months from the Closing of the Transaction or (ii) the SF Executive Officer
is hired by the KM General Partner and his employment is subsequently terminated
(including constructive termination) within 24 months from the Closing of the
Transaction (in each case other than for misconduct and disability):
    
 
        (1) a lump sum payment or installment payment equal to the sum of two
    times his base compensation or, in lieu thereof, the benefits provided under
    the SF General Partner's Severance Program dated October 30, 1987, as
    amended, (the "Severance Program");
 
   
        (2) a lump sum payment equal to two times the maximum incentive award to
    such SF Executive Officer under the SF General Partner's Annual Incentive
    Compensation Plan ("ICP Plan") as if all performance objectives were
    satisfied in full;
    
 
                                       73
<PAGE>
        (3) a tax make-whole payment to provide the benefits set forth above on
    an after-tax basis as long as the total benefits received do not exceed an
    individual's limit under Section 280G of the Code;
 
        (4) continuation of various insurance and health benefits for a period
    of 24 months (such benefits to be reduced to the extent comparable benefits
    are actually received from other sources by the SF Executive Officers during
    such period);
 
        (5) outplacement services for a period of 12 months;
 
        (6) with respect to phantom unit awards under Santa Fe's MLP Incentive
    Plan (the "MLP Plan"), a lump sum payment equal to the fair market value of
    any phantom unit awards granted but not yet paid; and
 
   
        (7) with respect to phantom Santa Fe Common Unit option awards under the
    Santa Fe 1997 Long-Term Incentive Unit Plan (the "LTIP"), a lump sum payment
    equal to the fair market value of the Santa Fe Common Units, less the option
    price reduced by prior distributions paid.
    
 
   
    The total amount payable, other than in respect to equity awards under the
above agreements, are estimated to be approximately $948,200 for Mr. Toole,
$749,000 for Mr. Abboud, $1,258,600 for Mr. Edwards, $1,003,000 for Mr. Pearl,
$431,500 for Mr. Cunningham and $403,000 for Mr. Boarts. In addition, certain of
the foregoing persons have claimed additional amounts that are disputed by Santa
Fe. These additional amounts are approximately $843,700 for Mr. Toole, $478,200
for Mr. Abboud, $118,900 for Mr. Pearl, $363,700 for Mr. Cunningham and $337,200
for Mr. Boarts.
    
 
   
    The SF Executive Officers have been granted the following number of phantom
Santa Fe Common Units under the MLP Plan. This plan provides that, upon a change
of control, an individual will receive a cash payment based upon the fair market
value of such Santa Fe Common Units as if all performance goals had been met.
Messrs. Toole, Abboud, Edwards, Pearl, Cunningham and Boarts have been granted
8,500, 3,300, 3,300, 3,000, 2,250 and 2,250 phantom Santa Fe Common Units,
respectively, which had a market value on January ___, 1998 of $    , $    ,
$    , $    , $    , and $    , respectively.
    
 
   
    The SF Executive Officers have also been granted the following number of
phantom Santa Fe options under the LTIP, at an exercise price of $38.75 per
Santa Fe Common Unit, less cash distributions paid. The LTIP provides that, upon
a change of control, an individual will receive a cash payment based on the
difference between the fair market value of the Santa Fe Common Units and the
exercise price. Messrs. Toole, Abboud, Edwards, Pearl, Cunningham and Boarts
have been granted 35,600, 14,000, 14,000, 13,300, 8,100 and 8,100 phantom Santa
Fe Common Unit options, respectively, which had a value on
1998 of $    , $    , $    , $    , $    and $    , respectively.
    
 
   
    It is expected that following the consummation of the Transaction, Mr. Toole
will execute a consulting agreement with BNSF whereby Mr. Toole will agree to
advise BNSF regarding pipeline matters for a period of five years after the
consummation of the Transaction and will receive a consulting fee of $100,000
per annum.
    
 
   
    As a result of the Transaction, directors of Santa Fe who are not employees
of Santa Fe or its affiliates will receive a lump sum payment equal to the
actuarial value of their vested pension benefits. Such payments are expected to
be approximately $    , $    and $    for Messers Adam, Godbold and Morphy,
respectively.
    
 
   
    Santa Fe and BNSF have agreed to indemnify the members of the Special
Committee with respect to their service as members of the Special Committee.
    
 
    The foregoing summary of the Employment Agreements, the Severance Program,
the MLP Plan and the LTIP is subject to the provisions of such agreements which
are incorporated by reference in the Registration Statement of which this Joint
Proxy Statement/Prospectus is a part.
 
    The Executive Officers and Directors of the SF General Partner collectively
own less than 1% of the outstanding Santa Fe Common Units.
 
                                       74
<PAGE>
    OFFICERS AND DIRECTORS OF THE KM GENERAL PARTNER.  The following describes
the interests in the Transaction of the directors and executive officers of the
KM General Partner, other than solely as holders of KM Common Units.
 
    Pursuant to KMEP's Executive Compensation Plan (the "KMEP Plan"), executive
officers of the KM General Partner are eligible for awards equal to a percentage
of the "Incentive Compensation Value," which is defined as cash distributions to
the KM General Partner during the four calendar quarters preceding the date of
redemption times eight (less a participant adjustment factor, if any). Under the
KMEP Plan, no eligible employee may receive a grant in excess of 2% and total
awards under the KMEP Plan may not exceed 10%.
 
    In general, participants may redeem vested awards in whole or in part from
time to time by written notice. KMEP may at its option pay the participant in
KMEP Common Units (PROVIDED, HOWEVER, the holders of KMEP must approve the plan
prior to issuing such units) or in cash. KMEP may not issue more than 200,000
KMEP Common Units in the aggregate under the KMEP Plan. KMEP Common Units will
not be issued to a participant unless such KMEP Common Units have been listed
for trading on the principal securities exchange on which KMEP Common Units are
then listed.
 
    The KMEP Plan terminates January 1, 2007 and any unredeemed awards will be
automatically redeemed. The Board of Directors of the KM General Partner may,
however, terminate the KMEP Plan before such date, and upon such early
termination, KMEP will redeem all unpaid grants of compensation at an amount
equal to the highest Incentive Compensation Value, using as the determination
date any day within the previous 12 months, multiplied by 1.5.
 
    To date, Thomas King, President of the KM General Partner, David Dehaemers,
Vice President and Chief Financial Officer of the KM General Partner, and Mike
Morgan, Vice President of the KM General Partner, have been granted awards
totaling 6% of Incentive Compensation Value. Fifty percent of such awards vest
January 1, 2000 and the remaining 50% vest January 1, 2002. It is anticipated
that the value of such awards will significantly increase as a result of the
Transaction.
 
   
    KM GENERAL PARTNER.  Under the terms of the KMEP Partnership Agreement, the
KM General Partner is entitled to receive a specified percentage of the
quarterly cash distributions to the partners of KMEP. The percentage varies
depending upon the amount of the quarterly distribution. See "Description of the
KMEP Partnership Agreement--Cash Distribution Policy." Based on KMEP's current
annual distribution of $2.00 per KMEP Common Unit, the KM General Partner would
receive approximately 14.5% of all such cash distributions and 50% of any
distributions in excess of such amount. Based on the anticipated post-Closing
annual distribution of $2.25 per KMEP Common Unit, the KM General Partner would
receive approximately 20.8% of all such cash distributions and 50% of any
distributions in excess of such amount. If the distribution percentages in the
Santa Fe Partnership Agreement rather than the KMEP Partnership Agreement were
used with an equivalent annual distribution of $3.1275 per unit ($2.25
multiplied by the Exchange Ratio), the KM General Partner would receive
approximately 7.7% of such cash distributions and 30% of any distributions in
excess of such amount. See "Risk Factors--Risks Associated with KMEP Partnership
Agreement and State Partnership Law--Differences in Cash Distribution Policies."
    
 
    In addition, as a result of the Transaction, the KM General Partner will be
required, pursuant to the terms of the KMEP Partnership Agreement and the
partnership agreement of OLP-D, to make an additional capital contribution to
KMEP of approximately $10.6 million.
 
                                       75

VREDS
 
   
    In September 1990, SF Holdings issued $218,981,000 principal amount of its
VREDs. Pursuant to the terms of the Purchase Agreement, KMEP has agreed to cause
OLP-D to perform all of SF Holdings' obligations under the VREDs from and after
the Closing. Any taxable gains related to the satisfaction and discharge of the
VREDs will be for the account of the SF General Partner or SF Holdings, as
applicable.
    
 
   
    The holders of the VREDs are entitled to receive interest payable quarterly
at a variable rate equal to the quarterly cash distributions on the number of
Santa Fe Common Units into which the VREDs are convertible upon the occurrence
of an Exchange Event (as defined in the VRED Indenture); provided, however, that
the minimum interest rate payable on the VREDs is 2% per quarter. Each $1,000
principal amount of VREDs is currently exchangeable into 37.2093 Santa Fe Common
Units. The SF General Partner owns 8,148,148 Santa Fe Common Units, which is
approximately equal to the total number of Santa Fe Common Units into which the
VREDs are exchangeable. The VRED Indenture prohibits the SF General Partner from
disposing of such Santa Fe Common Units.
    
 
   
    The Closing will constitute an Exchange Event. Upon the Exchange Event, SF
Holdings must enter into a supplemental indenture entitling the VRED holders to
exchange the VREDs for the consideration such holders would have received or
been entitled to receive after the Exchange Event had the VREDs been exchanged
for Santa Fe Common Units immediately prior to Closing. As a result, each $1,000
principal amount of VREDs will become exchangeable for 51.720927 KMEP Common
Units (which is equal to $   based on the closing price of the KMEP Common Units
on January   , 1998). The SF General Partner has agreed to place the
certificates representing the former 8,148,148 Santa Fe Common Units owned by
it, and the right to receive the 11,325,925 KMEP Common Units which will be
distributed in exchange for such Santa Fe Common Units, into escrow at Closing
(the "Escrow Units").
    
 
   
    As a result of the Transaction, VREDs are exchangeable for the KMEP Common
Units to be exchanged for Santa Fe Common Units pursuant to this Joint Proxy
Statement/Prospectus. Accordingly, after the Closing, OLP-D, on behalf of SF
Holdings, will commence an exchange offer for the VREDs in accordance with the
terms of the VRED Indenture ("VRED Exchange Offer"). SF Holdings would exchange
KMEP Common Units for the VREDs.
    
 
   
    VRED holders will have the right to exchange for KMEP Common Units during a
period of at least 30 consecutive days ("Exchange Period") selected by KMEP
beginning between 45-50 days after the Exchange Event. SF Holdings must give
notice of the Exchange Period to the VRED holders between 10-15 days before the
beginning of the Exchange Period (the "Exchange Notice"). The Exchange Notice
would indicate whether SF Holdings will (at the direction of KMEP) exercise its
option to deliver cash in lieu of KMEP Common Units. VREDs delivered for
exchange during the Exchange Period would be exchanged for the KMEP Common Units
on the date 90 days after the Exchange Event (the "VRED Exchange Date"). To the
extent that VREDs are not delivered for exchange, the Santa Fe Common Units into
which the VREDs were exchangeable (and representing the right to receive 1.39
KMEP Common Units per Santa Fe Common Unit) would be canceled. Any VREDs not
delivered for exchange during the Exchange Period become due and payable in full
in cash at par, plus accrued and unpaid interest, on the VRED Exchange Date.
    
 
   
    Subject to market conditions, KMEP intends to commence an underwritten
public offering for newly issued KMEP Common Units following the expiration of
the VRED Exchange Offer. Any holder of VREDs who exchanges VREDs pursuant to the
VRED Exchange Offer will be entitled to participate, as selling unitholders, in
this offering subject to such holders' execution of the appropriate documents
required by the managing underwriter and sharing of the fees and expenses of the
offering on a pro rata basis.
    
 
   
    The VRED Indenture permits SF Holdings the option (which would be exercised
by KMEP) to exchange the VREDs for cash equal to the "value of the VREDs" in
lieu of KMEP Common Units. The
    
 
                                       76
<PAGE>
   
"value of the VREDs" will be equal to the average of the closing prices of the
VREDs during 15 consecutive trading days chosen by KMEP during the 20
consecutive trading days preceding the Exchange Notice. The Exchange Notice must
indicate whether SF Holdings will (at the direction of KMEP) exercise its
option. KMEP currently does not have any intention to exchange the VREDs for
cash in lieu of KMEP Common Units and has not obtained a commitment for
financing such cash payment. However, depending on the comparative prices of
VREDs to KMEP Common Units and KMEP's ability to obtain financing, KMEP may
exercise this option to deliver cash in lieu of KMEP Common Units.
    
 
    KMEP intends to finance the payment at par of any VREDs not tendered in the
VRED Exchange Offer, or the payment of cash in lieu of delivering KMEP Common
Units, through the KMEP Loan Facility. See "--Credit Facilities--KMEP Loan
Facility."
 
SANTA FE FIRST MORTGAGE NOTES
 
   
    CONSENT SOLICITATION.  The closing of the Transaction is conditioned on
obtaining the consent thereto of the holders of the requisite percentage of the
outstanding principal balance of the Santa Fe First Mortgage Notes. The
substitution of OLP-D for the SF General Partner will require the consent of the
holders of a majority of the outstanding principal balance of the Santa Fe First
Mortgage Notes. The payment of the Special Distribution, as described under "The
Purchase Agreement--Special Distribution," and the payment to the SF General
Partner in connection with the Put Notice or the Call Notice will require the
consent of the holders of at least 66 2/3% of the outstanding principal balance
of the Santa Fe First Mortgage Notes to an amendment of the "Restricted
Payments" provision of the Santa Fe First Mortgage Notes to permit such
payments. These consents (other than a consent in connection with the Call
Notice which must be received prior to implementation of the call right but
which is not required for Closing) have been obtained by Santa Fe.
    
 
   
    POST-CLOSING COVENANTS.  Following the Closing, the SF Operating Partnership
may not (a) prepay, defease, purchase or otherwise retire the Santa Fe First
Mortgage Notes or any debt incurred as a result of any refinancing, refunding or
replacement thereof, but only with respect to the first $190 million thereof
(the "Indemnified Debt") (unless such Indemnified Debt is simultaneously
replaced with an equivalent amount of new Indemnified Debt providing for no
greater amortization), (b) modify any of the Indemnified Debt so as to eliminate
or limit the recourse liability of the SF Operating Partnership or the SF
General Partner with respect thereto, (c) merge or consolidate with or otherwise
become a corporation for federal income tax purposes or a limited liability
company, (d) cause or permit any other person or entity (other than the SF
Operating Partnership, the KM General Partner and OLP-D) to assume, guarantee,
indemnify against or otherwise incur any liability with respect to any
Indemnified Debt or (e) take or fail to take any other action (other than the
payment of the Indemnified Debt as originally scheduled) that would result in
the share of the Indemnified Debt which is allocated to the SF General Partner
for purposes of Section 752 of the Code and Treasury Regulations promulgated
thereunder to be reduced below $190 million.
    
 
    In addition, the SF Operating Partnership is required to use its reasonable
best efforts to refinance scheduled principal payments on the Indemnified Debt
with sufficient recourse debt so that at all times the amount of Indemnified
Debt which is allocable to the SF General Partner for purposes of Section 752 of
the Code is not less than $190 million.
 
    Following the Closing (i) the SF Operating Partnership is required to use
its reasonable best efforts to not take or omit to take any action, if such
action or omission (with the giving of notice or the passing of time, or both)
would constitute a breach of, or give rise to a default or event of default
under, any Indemnified Debt, and (ii) the SF General Partner will have the
right, but not the obligation, to arrange for the refinancing described above if
and only if the SF Operating Partnership is unable to do so as described above.
 
                                       77
<PAGE>
    The foregoing covenants terminate upon the exercise by the SF General
Partner of its put right, or by KMEP of its call right, with respect to the SF
General Partner's special limited partner interest in the SF Operating
Partnership. See "The Purchase Agreement--Put Right" and "The Purchase
Agreement--Call Right."
 
    Such restrictions may limit KMEP's flexibility in structuring or refinancing
existing or future indebtedness.
 
   
CREDIT FACILITIES
    
 
   
    KMEP CREDIT FACILITY.  KMEP has obtained a commitment letter from Goldman
Sachs Credit Partners L.P., as lead arranger and First Union Capital Markets
Corp., as co-arranger, for a $300 million revolving credit facility (the "KMEP
Loan Facility"). First Union National Bank will act as the Administrative Agent
and Goldman Sachs Credit Partners L.P. will act as the syndication agent. KMEP
and OLP-B will be co-borrowers under the KMEP Loan Facility. Commencing in May
2000, the amount available under the KMEP Loan Facility reduces on a quarterly
basis, with the final installment due in February 2005.
    
 
   
    The obligations of KMEP under the KMEP Loan Facility will be guaranteed by
the KMEP Partnerships and each other Restricted Subsidiary (as defined in the
KMEP Loan Facility) of KMEP (other than the SF Operating Partnership). KMEP will
guarantee the obligations of OLP-B under the KMEP Loan Facility. The KMEP Loan
Facility initially will be secured by, among other things, a first priority lien
on (i) KMEP's limited partner interests in the KMEP Partnerships; (ii) all of
the assets of OLP-D (including its general partner interest in the SF Operating
Partnership), (iii) KMEP's ownership interests in the fractionator and Shell
CO(2) Company and (iv) intercompany notes to be executed by each of the KMEP
Partnerships in favor of KMEP for loan proceeds lent to them by KMEP. If KMEP
fails to maintain certain financial ratios, then each of the KMEP Operating
Partnerships will secure its intercompany note with its assets.
    
 
   
    Interest on loans under the KMEP Loan Facility will accrue at KMEP's option
at a floating rate equal to either First Union National Bank's base rate (but
not less than the Federal Funds Rate plus .5% per annum) or LIBOR plus a margin
that will vary from .75% to 1.5% per annum depending upon the ratio of KMEP's
Funded Indebtedness to Cash Flow. Interest on advances will generally be payable
quarterly.
    
 
   
    The KMEP Loan Facility will include restrictive covenants that are customary
for this type of facility, including without limitation, the maintenance of
certain financial ratios and restrictions on (i) the incurrence of additional
indebtedness; (ii) entering into mergers, consolidations and sales of assets;
(iii) making investments; and (iv) granting liens. In addition, the KMEP Loan
Facility will generally prohibit KMEP from making cash distributions to holders
of KMEP Common Units more frequently than quarterly, from distributing amounts
in excess of 100% of Available Cash for the immediately preceding calendar
quarter and from making any distribution to holders of KMEP Common Units if an
event of default exists or would exist upon making such distribution.
    
 
   
    KMEP intends to use the net proceeds from the KMEP Loan Facility to fund (i)
the refinancing of approximately $133.8 million of existing indebtedness of
OLP-A and OLP-B, including the KMEP First Mortgage Notes and the related
make-whole premium (collectively, the "Refinanced Indebtedness"), (ii) OLP-D's
acquisition of the general partner interest in Santa Fe from the SF General
Partner for $84.4 million in cash, (iii) the $25 million cash contribution to be
made by KMEP to Shell CO(2) Company, (iv) the payment at par of any VREDs not
tendered in the exchange offer, (v) the fees, costs and expenses of the
Transaction (estimated to be approximately $13 million) and (vi) general working
capital and other general partnership purposes.
    
 
   
    The KMEP First Mortgage Notes were incurred in connection with the original
formation of KMEP. The remainder of the Refinanced Indebtedness was incurred for
working capital and general partnership
    
 
                                       78
<PAGE>
   
purposes. The KMEP First Mortgage Notes bear interest at a fixed rate of 8.79%
per annum. The remaining Refinanced Indebtedness bears interest at varying rates
(a weighted average rate of approximately 7.65% per annum as of December 31,
1997. The KMEP First Mortgage Notes are payable in 10 equal annual installments
of $11 million commencing in June 1998. The remaining Refinanced Indebtedness
was scheduled to mature in 1999.
    
 
   
    AMENDMENTS TO KMEP CREDIT FACILITIES.  The closing of the Transaction is
conditioned on obtaining the approval of the requisite lenders under (i) that
certain Credit Agreement dated as of February 14, 1997 among OLP-B, First Union
National Bank, as agent, and the lenders that are signatories thereto and (ii)
that certain Credit Agreement dated as of February 14, 1997 between KMI, First
Union National Bank, as agent, and the lenders that are signatories thereto.
Such approval has been obtained by KMEP.
    
 
   
    AMENDMENTS TO SANTA FE CREDIT FACILITIES.  The substitution of OLP-D for the
SF General Partner will require an agreement by lenders holding at least 34% of
the commitments under the Santa Fe Credit Agreement that such lenders will not
request the agent under such Credit Agreement to terminate the commitments
thereunder upon such substitution. The payment of the Special Distribution and
the payment to the SF General Partner in connection with the Put Notice or the
Call Notice will require the consent of lenders holding at least 66 2/3% of the
commitments under the Santa Fe Credit Agreement to an amendment of the
"Restricted Payments" provision of the Santa Fe Credit Agreement to permit such
payments. These consents (other than a consent in connection with the Call
Notice which must be received prior to implementation of the call right, but
which is not required for Closing) have been obtained by Santa Fe.
    
 
ACCOUNTING TREATMENT
 
    The Transactions will be accounted for by KMEP under the purchase method of
accounting. Under this method, the reported book value of the assets and
liabilities acquired from Santa Fe will be increased or decreased to their fair
value on the closing date and goodwill will be recorded to the extent that the
purchase price exceeds the fair value of the net assets. This goodwill, if any,
will be amortized by KMEP over a 40-year period or other acceptable period for
accounting purposes, but will not be amortizable for tax purposes. See "Material
Federal Income Tax Considerations--Tax Consequences of Holding KMEP Common
Units--Section 197 Intangibles."
 
REGULATORY APPROVALS
 
   
    ANTITRUST.  Although the Purchase Agreement provides that the Transaction
may not be consummated until notifications have been given and certain
information has been furnished to the Federal Trade Commission ("FTC") and the
Antitrust Division of the Department of Justice under the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act"), KMEP has been
advised by counsel, based on non-binding advice from the FTC's Premerger
Notification Office, that no filing is required since the Transaction does not
involve the acquisition or transfer of 100% of the interests in a partnership
due to the SF General Partner's retention of the .5% Special LP Interest in the
SF Operating Partnership. A filing will be required upon the exercise of the SF
General Partner's Put Right or KMEP's Call Right under the terms of the amended
and restated SF Operating Partnership Agreement. The parties to the Purchase
Agreement have waived the requirement for the closing of the Transaction that
the applicable waiting periods under the HSR Act have expired or been
terminated.
    
 
   
    CALIFORNIA PUC APPROVAL.  California law requires that a transfer of control
of any public utility doing business in California must be approved by the CPUC.
On October 29, 1997, KMEP filed an application with the CPUC for authority to
acquire control of Santa Fe. The application was noticed in the CPUC'S Daily
Calendar on November 3, 1997 and any protest to the application was to have been
filed by December 3, 1997. No protests were filed and the CPUC approval is
anticipated in late January or early February 1998.
    
 
                                       79
<PAGE>
FEDERAL SECURITIES LAW CONSEQUENCES
 
    All of the KMEP Common Units received or held by holders of Santa Fe Common
Units in connection with the Transaction will be freely transferable under the
Federal securities laws, except that KMEP Common Units received or held by
persons who are deemed to be "affiliates" (as such term is defined under the
Securities Act) of Santa Fe prior to the Transaction may be resold by them only
in transactions permitted by the resale provisions of Rule 145 promulgated under
the Securities Act (or Rule 144 in the case of such persons who become
affiliates of KMEP) or as otherwise permitted under the Securities Act. Persons
who may be deemed to be affiliates of KMEP or Santa Fe generally include
individuals or entities that control, are controlled by, or are under common
control with, such party and may include certain officers and directors of such
party as well as principal unit holders of such party. The Purchase Agreement
requires Santa Fe to use its reasonable best efforts to cause each of its
affiliates to execute a written agreement to the effect that such person will
not offer or sell or otherwise dispose of any KMEP Common Units issued to such
person in or pursuant to the Transaction in violation of the Securities Act or
the rules and regulations promulgated thereunder by the Commission.
 
LISTING ON THE NEW YORK STOCK EXCHANGE
 
   
    KMEP Common Units are currently listed for trading on the NYSE and it is
anticipated that such KMEP Common Units will continue to be traded thereon
immediately following consummation of the Transaction. The NYSE has approved for
listing on the NYSE the KMEP Common Units to be issued in connection with the
Transaction subject to unitholders' approval of the matters to be voted on at
the Special Meetings and official notice of issuance.
    
 
NO APPRAISAL RIGHTS
 
    Holders of Santa Fe Common Units are not entitled to any rights of appraisal
or similar rights of dissenters under the Delaware Act or the Santa Fe
Partnership Agreement in connection with the Transaction. Holders of KMEP Common
Units are not entitled to any rights of appraisal or similar rights of
dissenters under the Delaware Act or the KMEP Partnership Agreement in
connection with the matters to be considered at the KMEP Special Meeting.
 
EXPENSES AND FEES
 
    KMEP and Santa Fe estimate that the total fees, costs and expenses of the
Transaction will be approximately $13 million, which amount includes financial
advisor, legal and accounting fees and expenses and registration, recording,
filing and printing costs. If the Closing occurs, the SF General Partner will be
reimbursed by the SF Operating Partnership for the fees and expenses of the
Special Committee's financial advisors and counsel, all filing fees and expenses
related to the Transaction, all fees and expenses associated with the Santa Fe
Special Meeting, in each case, to the extent incurred by the SF General Partner;
PROVIDED, HOWEVER, that the SF General Partner will not be reimbursed by the SF
Operating Partnership or Santa Fe for any fees and expenses in connection with
the Purchase Agreement and the Transaction of the SF General Partner's financial
advisor, counsel or independent accountants or any losses for which it is
obligated to provide an indemnity under the Purchase Agreement.
 
    After the Closing, KMEP will (and will cause the SF Operating Partnership
to) reimburse the SF General Partner for all amounts for which Santa Fe would
have had a reimbursement obligation under the Santa Fe Partnership Agreement
(including without limitation post-retirement life insurance and medical
insurance employment benefits for former employees), except where such
reimbursement would be inconsistent with the preceding paragraph. This
reimbursement obligation generally terminates two years after the Closing,
except with respect to post-retirement life insurance and medical insurance
employment benefits for former employees.
 
                                       80
<PAGE>
    If the Closing does not occur, each of KMEP and Santa Fe and their
respective affiliates will bear their own fees and expenses, except that if (i)
Santa Fe terminates the Purchase Agreement as a result of a Superior Transaction
or (ii) the KM General Partner terminates the Purchase Agreement because the
Special Committee, during the pendency of a Superior Transaction (as defined
herein), withdraws, modifies or changes in a manner adverse to KMEP its
recommendation that the Santa Fe Common Unit holders approve the Transaction,
then in either case the SF General Partner will reimburse KMEP for up to $2.5
million of out-of-pocket expenses.
 
                             THE PURCHASE AGREEMENT
 
   
    The following is a brief summary of the Purchase Agreement. A copy of the
Purchase Agreement is included as Annex A in the Annex Volume that accompanies
and forms a part of this Joint Proxy Statement/Prospectus. This summary and the
statements made in this Joint Proxy Statement/Prospectus with respect to the
terms of the Purchase Agreement are qualified in their entirety by, and made
subject to, the more complete information contained in the Purchase Agreement.
    
 
ACQUISITION OF SANTA FE; ISSUANCE OF KMEP COMMON UNITS
 
    PURCHASE OF LIMITED PARTNER INTEREST IN THE SF OPERATING
PARTNERSHIP.  Pursuant to the Purchase Agreement, KMEP will purchase from Santa
Fe substantially all of Santa Fe's limited partner interest in the SF Operating
Partnership for a number of KMEP Common Units such that, upon liquidation of
Santa Fe, each holder of Santa Fe Common Units will have a right to receive 1.39
KMEP Common Units for each Santa Fe Common Unit held (which will result in the
issuance to the public holders of Santa Fe Common Units of an aggregate of
approximately 15.3 million KMEP Common Units and the issuance to the SF General
Partner of an aggregate of approximately 11.3 million KMEP Common Units; the
aggregate of all such KMEP Common Units distributed is referred to herein as the
"Unit Consideration"). As a result of the Transaction, the holders of the VREDs
will have the right to exchange the VREDs for the KMEP Common Units to be
received by the SF General Partner. The Purchase Agreement provides that it is a
condition to the closing of the Transaction that the Board of Directors of the
SF General Partner, the Special Committee and the KM General Partner must have
agreed on a mutually satisfactory plan for addressing issues associated with the
exchangeability of the VREDs, and that such arrangement has been accepted by
holders of a number of VREDs mutually satisfactory to the SF General Partner,
the Special Committee and the KM General Partner. The parties have not yet
agreed on a plan with respect to the VREDs. See "The Transaction--VREDs".
 
    PURCHASE OF GENERAL PARTNER INTEREST IN SANTA FE.  OLP-D will purchase from
the SF General Partner its general partner interest in Santa Fe for $84.4
million in cash (the "SF General Partner Consideration"). KMEP intends to borrow
the funds to finance OLP-D's purchase of the Santa Fe general partner interest
with the proceeds of the KMEP Loan Facility. See "The Transaction--Credit
Facilities--KMEP Loan Facility."
 
LIQUIDATION OF SANTA FE
 
    GENERAL.  Immediately following the consummation of the Transaction, OLP-D,
as the new general partner of Santa Fe, will cause the liquidation of Santa Fe
and, as a result of such liquidation, (i) each former Santa Fe Common Unit will
represent the right to receive 1.39 KMEP Common Units (the "Liquidation
Distribution") and (ii) OLP-D will receive the remainder of Santa Fe's limited
partner interest in the SF Operating Partnership and any remaining Santa Fe
assets in liquidation of its general partner interest in Santa Fe.
 
    AMENDMENT OF THE SANTA FE PARTNERSHIP AGREEMENT.  In connection with the
liquidation of Santa Fe, the Santa Fe Partnership Agreement will be amended (i)
to admit OLP-D as the general partner of
 
                                       81
<PAGE>
Santa Fe, (ii) to authorize the distributions to OLP-D and the holders of the
Santa Fe Common Units described above under "--General" and (iii) as required,
to implement the Transaction.
 
   
    FRACTIONAL UNITS.  No certificates or scrip representing fractional KMEP
Common Units will be issued upon the surrender for exchange of certificates
representing Santa Fe Common Units, and such fractional unit interests will not
entitle the owner thereof to vote or to any rights as a limited partner of KMEP.
Each holder of Santa Fe Common Units exchanged pursuant to the liquidation of
Santa Fe who would otherwise have been entitled to receive a fractional KMEP
Common Unit (after taking into account all KMEP Common Units to which such
holder is entitled pursuant to the exchange described herein) (a "fractional
unit interest") will receive from KMEP in exchange for such fractional unit
interest, upon delivery of the Certificates to the Exchange Agent (each as
defined below), an amount in cash (payable in dollars, without interest) equal
to the product obtained by multiplying (A) the fractional unit interest to which
such holder would otherwise be entitled by (B) the average of the high and low
trading prices of KMEP Common Units on the NYSE on the last trading day prior to
the Closing ("Fractional Unit Payment").
    
 
    EXCHANGE AGENT.  OLP-D has appointed First Chicago Trust Company of New York
to act as exchange agent (the "Exchange Agent") for the payment of the
Liquidation Distribution and any Fractional Unit Payment. At or prior to the
Closing, KMEP will cause OLP-D to deposit with the Exchange Agent, for the
benefit of the holders of Santa Fe Common Units, the estimated aggregate
Fractional Unit Payment (the "Exchange Fund") and KMEP will authorize the
Exchange Agent to issue KMEP Common Units, constituting the Liquidation
Distribution, for exchange. KMEP will cause OLP-D to deposit with the Exchange
Agent any additional funds in excess of the Exchange Fund as necessary to pay
any Fractional Unit Payment required to be paid under the Purchase Agreement.
Any KMEP Common Units, or fractional unit interest, and any remaining amount of
the Exchange Fund or other funds deposited, after the earlier to occur of (i)
payment in full of all amounts due to the holders of the Certificates or to the
Exchange Agent or (ii) the expiration of the period specified under
"--Termination of Exchange Fund," will be returned to KMEP or OLP-D, as
applicable.
 
    EXCHANGE PROCEDURES.  Promptly after the Closing, the Exchange Agent will
mail to each record holder, as of the Closing, of an outstanding certificate or
certificates that immediately prior to the Closing represented Santa Fe Common
Units (the "Certificates"), a form of letter of transmittal (the "Letter of
Transmittal") for use in effecting the surrender of the Certificates and payment
therefor. Upon surrender to the Exchange Agent of such Certificates, together
with such properly completed and duly executed Letter of Transmittal, the holder
of a Certificate will be entitled to a certificate or certificates representing
the number of full KMEP Common Units into which the Certificates surrendered
will have been converted pursuant to the Purchase Agreement and the Fractional
Unit Payment, if any, payable in redemption of any fractional KMEP Common Unit
otherwise issuable. Until surrendered as contemplated by this paragraph, each
Certificate will be deemed at any time after the Closing to represent only the
right to receive upon such surrender the Liquidation Distribution and Fractional
Unit Payment, if any, as contemplated herein. No interest will be paid or will
accrue on any Fractional Unit Payment.
 
    LOST OR STOLEN CERTIFICATES.  The instructions in the Letter of Transmitted
will set forth procedures that must be taken by the holder of any Certificate
that has been lost, destroyed or stolen. It will be a condition to the right of
such holder to receive a certificate representing KMEP Common Units and the
Fractional Unit Payment, if any, that the Exchange Agent receive, along with the
Letter of Transmittal, a duly executed lost certificate affidavit, including an
agreement to indemnify KMEP and OLP-D, signed exactly as the name or names of
the registered holder or holders appeared on the books of Santa Fe immediately
prior to the Closing, together with a customary bond and such other documents as
KMEP or OLP-D may reasonably require in connection therewith.
 
    NO TRANSFER OF SANTA FE COMMON UNITS AFTER CLOSING.  After the Closing,
there will be no further transfer on the records of Santa Fe or its transfer
agent of Certificates and if such Certificates are presented to Santa Fe for
transfer, they will be canceled against delivery of the certificate or
certificates for
 
                                       82
<PAGE>
KMEP Common Units and Fractional Unit Payments, if any. If any certificate for
such KMEP Common Units is to be issued to a person or entity other than the
record holder of a Certificate surrendered for exchange, it will be a condition
of such exchange that the Certificate so surrendered be properly endorsed, with
signature guaranteed, or otherwise in proper form for transfer and that the
person requesting such exchange pay to OLP-D or the Exchange Agent any transfer
or other taxes required by reason of the issuance of certificates for such KMEP
Common Units in a name other than that of the record holder of the Certificates
surrendered, or establish to the reasonable satisfaction of OLP-D or the
Exchange Agent that such tax has been paid or is not applicable.
 
    DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED UNITS.  No dividends or other
distributions with respect to KMEP Common Units with a record date after the
Closing will be paid to the holder of any unsurrendered Certificate with respect
to the KMEP Common Units issuable in respect thereof and no Fractional Unit
Payment will be paid to any such holder until the surrender of such Certificate.
Subject to the effect of applicable laws, there will be paid to the holder of
the Certificate, without interest, (i) at the time of surrender of any such
Certificate, the amount of any Fractional Unit Payment to which such holder is
entitled and the amount of dividends or other distributions previously paid with
respect to such whole KMEP Common Units with a record date after the Closing and
(ii) at the appropriate payment date, the amount of dividends or other
distributions payable with respect to such whole KMEP Common Units with a record
date after the Closing and prior to such surrender and a payment date subsequent
to such surrender.
 
    NO FURTHER OWNERSHIP RIGHTS IN SANTA FE COMMON UNITS.  All KMEP Common Units
issued upon the surrender for exchange of Certificates (including any Fractional
Unit Payment) will be deemed to have been issued (and paid) in full satisfaction
of all rights pertaining to the Santa Fe Common Units represented by such
Certificates. Full satisfaction is subject to KMEP's obligation, with respect to
Santa Fe Common Units outstanding immediately prior to the Closing, to pay any
dividends or make any other distributions with a record date prior to the
Closing that may have been declared or made by Santa Fe on such Santa Fe Common
Units in accordance with the terms of the Purchase Agreement on or prior to the
Closing and which remain unpaid at the Closing.
 
    TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange Fund that remains
undistributed to the holders of the Certificates for twelve months after the
Closing will be delivered to KMEP, upon demand, and any holders of Santa Fe
Common Units who have not properly surrendered their Certificate must look only
to KMEP, and only as general creditors of KMEP, for payment of their claim for
KMEP Common Units, any Fractional Unit Payment and any dividends or
distributions with respect to KMEP Common Units to which such holders may be
entitled.
 
    NO LIABILITY.  None of KMEP, OLP-D, Santa Fe or the Exchange Agent will be
liable to any person in respect of any KMEP Common Units (or dividends or
distributions with respect thereto) or Fractional Unit Payment delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law. If any Certificates have not been surrendered prior to such date on
which any KMEP Common Units, any Fractional Unit Payment or any dividends or
distributions with respect to KMEP Common Units in respect of such Certificate
would escheat to or become the property of any governmental entity or authority,
any such shares, cash, dividends or distributions in respect of such
Certificates will, to the extent permitted by applicable law, become the
property of OLP-D, free and clear of all claims or interest of any person or
entity previously entitled thereto other than the holder of such Certificate.
 
AMENDMENT OF THE SF OPERATING PARTNERSHIP AGREEMENT
 
    Following the Closing, the Amended and Restated Agreement of Limited
Partnership of the SF Operating Partnership dated December 19, 1988 ("SF
Operating Partnership Agreement") will be amended and restated to convert the
approximate 99% limited partner interest held by OLP-D to a general partner
interest and to convert the SF General Partner's approximate 1% general partner
interest
 
                                       83
<PAGE>
to the Special LP Interest. The Special LP Interest is non-transferrable, except
to affiliates of the SF General Partner or as described below. In addition, such
interest will have no voting rights except with respect to mergers,
consolidations or the dissolution and liquidation of the SF Operating
Partnership.
 
    In addition, the SF Operating Partnership Agreement will be amended to
provide that the rights of OLP-D, as general partner of the SF Operating
Partnership, and the KM General Partner, as general partner of OLP-D, will be
subrogated to the rights of any holder of Indemnified Debt to the extent that
either entity acting as a general partner of the SF Operating Partnership
Agreement or OLP-D, as applicable, made any payment with respect to such
Indemnified Debt. See "--Indemnification."
 
SPECIAL DISTRIBUTION
 
    Immediately following the consummation of the Transaction, OLP-D will cause
the SF Operating Partnership to redeem approximately one-half of the Special LP
Interest in the SF Operating Partnership, in exchange for $5.8 million (which
the parties agreed represented the fair market value of such interest on the
date of the Purchase Agreement) (the "Special Distribution"). Upon the payment
of the Special Distribution and the redemption of such interest, the Special LP
Interest will be reduced to .5% and the general partner interest of OLP-D in the
SF Operating Partnership will be increased to 99.5%. The Special Distribution
will be paid solely from the funds of the SF Operating Partnership, and not
indirectly or directly from the funds of KMEP or any of its other affiliates.
 
PUT RIGHT
 
    After January 1, 1999, the SF General Partner may require, pursuant to 30
days' written notice, the SF Operating Partnership to purchase (the "Put/Call
Consideration" and together with the Unit Consideration, the SF General Partner
Consideration and the Special Distribution, the "Aggregate Consideration") all
of the SF General Partner's Special LP Interest in the SF Operating Partnership
(the "Put Notice"). The purchase price will consist of cash in the amount equal
to the fair market value on the date of the Put Notice of 115,973 KMEP Common
Units (the "Put/Call Units"). The SF Operating Partnership may, in its sole
discretion, elect to have an affiliate make such purchase or deliver KMEP Common
Units in lieu of making such cash payment.
 
CALL RIGHT
 
    Upon 30 days' written notice to the SF General Partner (the "Call Notice"),
OLP-D or its designated affiliate may redeem the SF General Partner's Special LP
Interest in the SF Operating Partnership. The purchase price of such interest
will consist of (i) the payment of the cash price or the issuance of the Put/
Call Units as provided above (see "--Put Right") and (ii) an additional amount
of cash sufficient to result in the SF General Partner receiving on an after-tax
basis an additional amount of cash equal to any incremental gain realized by the
SF General Partner resulting from a decrease in its share of partnership debt
multiplied by the maximum net marginal statutory federal and state income tax
rates applicable to the SF General Partner.
 
REGISTRATION RIGHTS OF THE SF GENERAL PARTNER
 
   
    If an election is made to issue the Put/Call Units to the SF General Partner
rather than cash for the SF General Partner's Special LP Interest in the SF
Operating Partnership, as discussed herein (See "--Put Right" and "--Call
Right"), then KMEP and the KM General Partner must either (i) register the
resale of the Put/Call Units under the Securities Act within 90 days of such
issuance and cause the Put/Call Units to be approved for issuance on the NYSE,
(ii) provide the SF General Partner with an opinion of counsel that registration
of the Put/Call Units is not required or (iii) cause the SF Operating
Partnership or an affiliate to pay the SF General Partner the cash purchase
price in lieu of the issuance of the Put/Call Units.
    
 
                                       84
<PAGE>
INDEMNIFICATION
 
   
    KMEP.  From and after the Closing, KMEP will (and will cause the SF
Operating Partnership to) indemnify the SF General Partner, SF Holdings and
their stockholders, officers, directors, affiliates, successors and assigns from
any loss relating to (i) Santa Fe or the SF Operating Partnership (whether prior
to or after the Closing), (ii) the VREDs (except for taxable gain applicable to
the SF General Partner or SF Holdings), (iii) the severance costs described
under "--Severance Obligations" in excess of the $4.5 million referred to in
such paragraph or any action taken by KMEP or the KM General Partner in
connection with such severance costs; provided that KMEP will not be obligated
to indemnify the SF General Partner, SF Holdings and their stockholders,
officers, directors, affiliates, successors and assigns for up to an additional
$1 million relating to certain disputed severance obligations, or (iv) certain
amounts for which the SF General Partner would have been entitled to
reimbursement under the Santa Fe Partnership Agreement, except in each case for
losses for which the SF General Partner is indemnifying KMEP and its affiliates
as described below (see "The Transaction--Expenses and Fees").
    
 
    SANTA FE.  From and after the Closing, the SF General Partner will indemnify
the KM General Partner and OLP-D from any loss relating to any payment that
OLP-D, as the general partner of the SF Operating Partnership, or the KM General
Partner, as the general partner of OLP-D, is required to make (and makes) from
its own funds (after prior recourse is had to the assets of the SF Operating
Partnership) with respect to the Santa Fe First Mortgage Notes and any
refinancing, refunding or replacement thereof due to the inability of the SF
Operating Partnership to pay or refinance such Indemnified Debt. Such indemnity
is limited to the amount of $190 million. The SF General Partner will be
subrogated to such rights of OLP-D to the extent that the SF General Partner has
made any payment in respect of the Debt Indemnity. See "The Transaction--Santa
Fe First Mortgage Notes."
 
    The SF General Partner, from and after the Closing, will indemnify and hold
harmless the KM General Partner, KMEP, OLP-D and their respective stockholders,
unit holders, officers, directors, affiliates, successors and assigns from and
against any and all losses relating to any claim for money damages by any
limited partner of Santa Fe (other than KMEP and its affiliates) relating to the
fairness of the Transaction to such limited partners; PROVIDED, HOWEVER, that
any liability for fees and expenses of attorneys for any such limited partner of
Santa Fe will be borne in equal halves by the SF General Partner, on the one
hand, and the KM General Partner, KMEP and OLP-D, on the other hand. In the
event that any such litigation is pending at the time of the Closing of the
Transaction, the SF General Partner may elect to not close the Transaction,
unless KMEP, the KM General Partner and OLP-D waive their right to such
indemnification or demonstrate to the SF General Partner that such claims have
been settled or compromised on terms acceptable to the SF General Partner.
 
    From and after the Closing, the SF General Partner will also indemnify KMEP,
the KM General Partner, OLP-D and their respective stockholders, unitholders,
officers, directors, affiliates, successors and assigns from any losses relating
to (i) any material breach of the representation and warranty relating to Santa
Fe's ownership of the SF Operating Partnership or the SF General Partner's
ownership of the general partner interest in Santa Fe, (ii) any taxes assessed
against KMEP or the KM General Partner due to the liquidation of Santa Fe, (iii)
any claim by any holder of the VREDs or the Santa Fe First Mortgage Notes or by
any lender under the Santa Fe Credit Agreement (other than KMEP or its
affiliates) with respect to the VREDs, the Santa Fe First Mortgage Notes or the
Santa Fe Credit Agreement, to the extent relating to any act or omission of the
SF General Partner, SF holdings or their respective affiliates as long as such
claim arises and is asserted prior to the Closing and does not relate to the
Transaction, (iv) the expenses and fees that the SF General Partner is obligated
to pay under the Purchase Agreement, (v) certain employee benefits and (vi)
certain excluded reimbursement items.
 
SEVERANCE OBLIGATIONS
 
   
    Generally, KMEP will be responsible for all severance costs above $4.5
million incurred by the SF General Partner; provided that, in addition to the
first $4.5 million of severance costs, the Santa Fe General Partner will pay up
to $1.0 million in additional severance claimed by several employees but
    
 
                                       85
<PAGE>
   
disputed by Santa Fe, if such dispute is resolved. These severance costs include
anything (a) arising under the Severance Program (including related litigation
costs and other than accrued or earned vacation) with respect to the employees
who are employed by the SF General Partner in connection with the business of
Santa Fe and the SF Operating Partnership not hired by the KM General Partner at
Closing or who are not otherwise retained by the SF General Partner or the KM
General Partner beyond three months following the Closing or who are hired by
the KM General Partner and terminated within one year of the Closing, (b)
arising under specified portions of the Employment Agreements between the SF
General Partner and Messrs. Toole, Cunningham, Boarts, Pearl, Abboud and Edwards
on account of a "change of control", except for any tax gross-up payment, (c)
related to payments under specified stock, phantom stock, unit or phantom unit
plans maintained by the SF General Partner that are payable as a result of the
Transaction or (d) arising by operation of law. See "The Transaction--Interests
of Certain Persons in the Transaction-- Officers and Directors of the SF General
Partner."
    
 
CERTAIN COVENANTS
 
    ELIMINATION OF INTER-COMPANY ITEMS.  Prior to the Closing, Santa Fe or the
SF Operating Partnership will fully repay or capitalize any indebtedness owed by
either of the Santa Fe Partnerships to any affiliate of Santa Fe. In addition,
all inter-company accounts between the SF Operating Partnership and Santa Fe on
the one hand and any affiliate on the other will be eliminated or fully paid by
capital contribution, dividend or payment.
 
    NO SOLICITATION.  Except as provided in the following paragraph, the SF
General Partner (on behalf of itself, Santa Fe and the SF Operating Partnership)
and Santa Fe agreed to terminate all discussions and negotiations with others
regarding a sale or other transaction involving the partnership interests to be
acquired in the Transaction, the assets, business or securities of Santa Fe or
the SF Operating Partnership or any other transaction similar to the Transaction
(collectively, the "Possible Alternatives"). In addition, the SF General Partner
and Santa Fe agreed that, so long as the Purchase Agreement remains in effect,
they would not, directly or indirectly, (i) solicit, initiate, encourage
(including by way of furnishing information or assistance), conduct discussions
with or engage in negotiations with or take any other action to facilitate, any
inquiries, or the making of any proposal which constitutes or may reasonably be
expected to lead to a Possible Alternative, (ii) enter into an agreement with
any person or entity, other than KMEP or its affiliates, providing for a
Possible Alternative, (iii) make or authorize any statement, recommendation or
solicitation in support of any Possible Alternative by any person or entity,
other than by KMEP or its affiliates, or (iv) subject to the fiduciary duties of
the SF General Partner, its Board of Directors and the Special Committee under
applicable law, withdraw or qualify the recommendation of the Transaction by the
Board of Directors of the SF General Partner.
 
    The SF General Partner, Santa Fe and the SF Operating Partnership will be
entitled to take any action otherwise prohibited by the preceding paragraph in
response to any third party inquiry, contact or proposal received by them if (a)
the initial inquiry, contact or proposal from any third party was not received
in violation of the preceding paragraph, (b) the Special Committee has
determined, in its good faith judgment, that any such otherwise prohibited
action may lead to the negotiation and consummation of a Possible Alternative
that in the opinion of the Special Committee may be more beneficial than the
Transaction, taken as a whole, to the holders of the Santa Fe Common Units,
other than the SF General Partner and its affiliates (a "Superior Transaction"),
and (c) the Special Committee has determined, after consultation with and based
on the advice of its legal counsel, that the failure to take such action would
be inconsistent with the SF General Partner's or its Board of Directors'
fiduciary duties to holders of Santa Fe Common Units under applicable law;
provided, that none of the SF General Partner, Santa Fe or the SF Operating
Partnership may execute a binding agreement to effect a Superior Transaction,
unless the Purchase Agreement has first been terminated as provided under
"--Termination." The SF General Partner, Santa Fe and the SF Operating
Partnership agreed to notify KMEP immediately if any inquiry, contact or
proposal is received by, any such information is requested from, or any such
discussions or negotiations are sought to be initiated or continued with, any of
its representatives, and thereafter to keep
 
                                       86
<PAGE>
KMEP informed, on a current basis, on the status of any such inquiry, contact or
proposal and the status of any such negotiations or discussions.
 
CLOSING DATE
 
   
    The Purchase Agreement provides that the Closing will occur on or before the
third business day following the satisfaction of the conditions set forth in the
Purchase Agreement or such other place, date and time as mutually agreed upon by
the parties to the Purchase Agreement.
    
 
CONDITIONS
 
    The respective mutual obligations of KMEP and Santa Fe to effect the
Transaction are subject to the satisfaction of certain customary conditions,
which include, among others: (i) the matters submitted for approval at the
Special Meetings must have been approved, (ii) certain of Santa Fe's and KMEP's
lenders must have approved the Transaction, (iii) all governmental approvals and
consents must have been obtained, including the approval of the California
Public Utilities Commission, (iv) the Special Committee, the SF General Partner
and the KM General Partner must have agreed on a mutually satisfactory plan for
addressing issues associated with the exchangeability of the VREDs, and such
arrangements must have been accepted by holders of a number of VREDs mutually
satisfactory to the SF General Partner, the Special Committee and the KM General
Partner, (v) Mayer, Brown & Platt must have delivered to Santa Fe and KMEP at
the Closing an opinion with respect to the matters under "Material Federal
Income Tax Considerations--Tax Consequences of the Exchange and Distribution,"
and (vi) Morrison & Hecker L.L.P. must have delivered to Santa Fe and KMEP at
the Closing an opinion with respect to the matters under "Material Federal
Income Tax Considerations--Legal Opinions and Advice." In addition, Santa Fe is
not required to close the Transaction if on the date of the Closing any of the
Santa Fe Common Unit holder Suits (or any similar action by a limited partner of
Santa Fe relating to the fairness of the Transaction to such limited partners)
is pending, unless KMEP, the KM General Partner and OLP-D have (i) waived their
right to indemnification from the SF General Partner with respect to such
actions (see "--Indemnification--Santa Fe") or (ii) demonstrated to the
satisfaction of the SF General Partner that such claims have been settled or
compromised on terms acceptable to the SF General Partner.
 
SURVIVAL
 
    The representations and warranties made by the parties in the Purchase
Agreement will not survive the Closing, other than the SF General Partner's
representation regarding the ownership of the general partner interest in Santa
Fe, which survives for two years after Closing.
 
TERMINATION
 
    The Purchase Agreement is subject to termination by:
 
        (a) THE KM GENERAL PARTNER AND THE SF GENERAL PARTNER, upon their mutual
    written agreement;
 
        (b) THE SF GENERAL PARTNER, (i) if KMEP or the KM General Partner fails
    to perform in any material respect their respective agreements contained in
    the Purchase Agreement or materially breach any of their representations,
    warranties or covenants contained in the Purchase Agreement, (which failure
    or breach would relieve Santa Fe, the SF General Partner and SF Holdings of
    their obligations to close the Transaction) if such breach cannot be cured
    prior to the Closing or is not cured within 45 days after the SF General
    Partner has given notice of such breach; (ii) upon the occurrence of any
    event that would reasonably be expected to have a material adverse effect on
    KMEP; (iii) acting through the Special Committee, if the Special Committee
    determines that a Possible Alternative would constitute a Superior
    Transaction; or (iv) if the Board of Directors of the KM General Partner
    withdraws, modifies or changes in a manner adverse to Santa Fe, the SF
    Operating Partnership and SF Holdings its recommendation that the holders of
    KMEP Common Units approve the issuance of KMEP Common Units on the terms and
    conditions in the Purchase Agreement;
 
                                       87
<PAGE>
        (c) THE KM GENERAL PARTNER, (i) if any of Santa Fe, the SF General
    Partner or SF Holdings fails to perform in any material respect their
    respective agreements contained in the Purchase Agreement or materially
    breach any of its representations, warranties or covenants contained in the
    Purchase Agreement, (which failure or breach would relieve KMEP and the KM
    General Partner of their obligations to close the Transaction) if such
    breach cannot be cured prior to the Closing or is not cured within 45 days
    after the KM General Partner has given notice of such breach; (ii) upon the
    occurrence of any event that would reasonably be expected to have a material
    adverse effect on Santa Fe or the SF Operating Partnership; or (iii) if the
    SF Board of Directors or the Special Committee withdraws, modifies or
    changes in a manner adverse to KMEP its recommendation that the holders of
    Santa Fe Common Units approve the Transaction; or
 
   
        (d) EITHER THE KM GENERAL PARTNER OR THE SF GENERAL PARTNER, (i) if
    there is any order of any court or governmental or regulatory agency which
    prohibits or restrains Santa Fe, the SF Operating Partnership, SF Holdings,
    KMEP or the KM General Partner from consummating the Transaction; (ii) if
    the Closing has not occurred by March 16, 1998; subject to extension to June
    30, 1998, if additional time is required to obtain the approval of the
    California Public Utilities Commission; (iii) if the matters submitted for
    approval at the Special Meetings are not approved; or (iv) if the average of
    the daily high and low trading prices of KMEP Common Units on the NYSE for
    any 20 consecutive trading days is less than $31.32 or greater than $46.98
    (the Special Committee may also terminate the Purchase Agreement pursuant to
    this clause (iv)).
    
 
EFFECT OF TERMINATION
 
    NO LIABILITY.  If the Purchase Agreement is terminated in accordance with
its terms (other than as a result of a Superior Transaction), no party hereto
(or its officers or directors) will have any liability or further obligation to
any other party to the Purchase Agreement, except for certain obligations
related to confidential information and any liability resulting from the breach
of the Purchase Agreement.
 
    EXPENSE REIMBURSEMENT.  If the Purchase Agreement is terminated by the SF
General Partner because the Special Committee has determined that a Possible
Alternative would constitute a Superior Transaction or by the KM General Partner
because the Special Committee, during the pendency of a Superior Transaction,
withdraws, modifies or changes in a manner adverse to KMEP its recommendation
that the Santa Fe Common Unit holders approve the Transaction, then the SF
General Partner must pay or cause to be paid to KMEP its actual third party
expenses arising out of the Transaction up to a maximum of $2.5 million, and
upon receipt of such amount KMEP and the KM General Partner will have no further
recourse or claim against any party. No obligations of the SF General Partner,
Santa Fe or the SF Operating Partnership under the Purchase Agreement will be
terminated until such payment has been made.
 
AMENDMENT; WAIVER
 
    The Purchase Agreement may not be altered, modified or amended except
pursuant to a written instrument signed by the party to be bound. The failure of
any party to exercise any right or remedy under the Purchase Agreement will not
be deemed or constitute a waiver of such right or remedy in the future.

             UNAUDITED KMEP PRO FORMA COMBINED FINANCIAL STATEMENTS
 
   
    The unaudited pro forma combined financial statements of KMEP have been
derived from the historical balance sheet and income statements of KMEP and
Santa Fe as of September 30, 1997 and for the year ended December 31, 1996 and
the nine months ended September 30, 1997. The unaudited pro forma combined
financial statements have been prepared to give effect to the acquisition of
Santa Fe through the issuance of 1.39 Common Units of KMEP for each outstanding
Santa Fe Common Unit and the purchase of the general partner interest of Santa
Fe for $84.4 million in cash using the purchase method of accounting. The
unaudited pro forma combined balance sheet has been prepared assuming the
Transaction, the formation of Shell CO(2) Company and the refinancing of
existing indebtedness had been consummated on September 30, 1997. In addition,
the unaudited pro forma combined financial statements assume that all of the
VREDs are exchanged in the VRED Exchange Offer. The unaudited pro forma combined
statements of income for the nine and twelve month periods ending September 30,
1997 and December 31, 1996, respectively, have been prepared assuming the
Transaction had been consummated on January 1, 1996.
    
 
    The purchase price allocated in the unaudited pro forma combined financial
statements is based on management's preliminary estimate of the fair market
values of assets acquired and liabilities assumed and subject to adjustment. The
final allocation of the purchase price will be based on the fair market values
determined by valuations and other studies which are not yet completed.
 
    The unaudited pro forma combined financial statements include assumptions
and adjustments as described in the accompanying notes and should be read in
conjunction with the historical financial statements and related notes of KMEP
and Santa Fe incorporated by reference herein.
 
    The unaudited pro forma combined financial statements may not be indicative
of the results that would have occurred if the Transaction had been consummated
on the dates indicated or which will be obtained in the future.

BASIS OF PRESENTATION
 
   
    The following described pro forma adjustments give recognition to the
acquisition of Santa Fe through the issuance of 1.39 KMEP Common Units at an
assumed unit price of $39.00 to the public holders of Santa Fe Common Units for
each outstanding Santa Fe Common Unit, the redemption of the SF General Partner
interest for $84,400 in cash, a KM General Partner cash contribution of $10,592,
the refinancing of existing indebtedness and the proposed purchase of a 20%
interest in Shell CO(2) Company.
    
 
(a) Reflects the preliminary allocation of the total purchase price in excess of
    the net assets acquired to estimated fair value of property, plant and
    equipment utilizing the purchase method of accounting for the Transaction as
    of September 30, 1997. The purchase price allocation is subject to revision
    based on a preliminary appraisal. The valuation of the assets and
    liabilities is not complete as of the date of this filing.
 
    The purchase price is calculated as follows:

    $11 million make-whole premium on certain of the existing debt. The payment
    of such make-whole premium will result in an extraordinary loss of
    approximately $11 million which is reflected in the Pro Forma Balance Sheet
    as a reduction to Partners Capital and minority interest. The extraordinary
    loss and the interest expense associated with borrowings related to the
    make-whole premium and the investment in the Shell CO(2) Company are not
    directly related to the Transaction and are not reflected in the Pro Forma
    Combined Statement of Income. The extraordinary loss will be recorded when
    the refinancing occurs, which is anticipated to be in the first quarter of
    1998.
    
 
   
(e) Gives effect to the utilization of $5,800 of SF Operating Partnership cash
    to redeem a .5101% Special LP Interest owned by the SF General Partner.
    
 
(f) To give effect to the removal of the SF General Partner as general partner
    of Santa Fe.
 
(g) To account for the additional $10,592 cash contribution to OLP-D (minority
    interest of 1.0101%).
 
(h) To reduce operating and general and administrative expenses for the costs
    related to certain employees involuntarily terminated in connection with the
    Transaction. KMEP management has made explicit determinations of salary,
    benefit, and other cost reductions resulting from these terminations. Such
    reductions will have a continuing impact on expenses in future periods. None
    of the identified terminations or cost reductions will reduce revenues or
    efficiency of operations.
 
(i) To record estimated additional depreciation expense using a remaining useful
    life of 40 years. The actual range of useful lives will not be known until a
    formal analysis and appraisal of assets acquired is completed.
 
   
(j) Reflects incremental interest expense on new debt associated with the
    Transaction of $67,608 at an assumed rate of 7.1% as discussed in (d) above.
    
 
(k) Gives effect to the redemption of the .5101% Special LP Interest in
    connection with the Transaction. Pursuant to the Purchase Agreement, the SF
    Operating Partnership will redeem a portion of the Special LP Interest from
    the SF General Partner for $5,800. These amounts reduce Partners Capital-
    KMEP Common Units by $5,067, Partners Capital-KM General Partner by $51, and
    minority interest by $52 (see note e). This leaves the SF General Partner
    with a remaining minority Special LP Interest of .5% in the SF Operating
    Partnership.
 
(l) Gives effect to the allocation of pro forma net income to the general
    partner and the limited partners resulting from the utilization of KMEP
    partnership sharing ratios. Amounts are calculated giving consideration to
    cash available for distribution after certain anticipated cost savings and
    interest expense (see notes h and j, respectively). The KM General Partner's
    interest in net income includes incentive distributions the KM General
    Partner would have received based on total distributions. These incentive
    distributions are greater under the KMEP Partnership Agreement than they
    would have been under the Santa Fe Partnership Agreement.

                   COMPARISON OF COMMON UNIT HOLDERS' RIGHTS
 
    If the Transaction is consummated, all holders of Santa Fe Common Units will
become holders of KMEP Common Units following the liquidation of Santa Fe. For a
description of the KMEP Partnership Agreement, see "Description of KMEP
Partnership Agreement" and "Material Federal Income Tax Considerations."
Although the rights and obligations of, and matters affecting, the holders of
KMEP Common Units and Santa Fe Common Units are substantially similar, a number
of significant differences exist between the KMEP Partnership Agreement and the
Santa Fe Partnership Agreement. The following is a summary of the material
differences between the respective rights and obligations of, and matters
affecting, the holders of KMEP Common Units and Santa Fe Common Units. This
summary is qualified in its entirety by reference to the Delaware Act, the KMEP
Partnership Agreement and the Santa Fe Partnership Agreement.

                                            finally, to all partners in accordance
                                            with their respective percentage interest
                                            in Santa Fe.

                   DESCRIPTION OF KMEP PARTNERSHIP AGREEMENT
 
   
    The following paragraphs are a summary of certain provisions of the KMEP
Partnership Agreement. A copy of the KMEP Partnership Agreement is included as
Annex D in the Annex Volume that accompanies and forms a part of this Joint
Proxy Statement/Prospectus. Unless otherwise specifically described, references
herein to the term "KMEP Partnership Agreement" constitute references to the
partnership agreements of KMEP, OLP-D, the KMEP Operating Partnerships and the
SF Operating Partnership, collectively. OLP-D and the KMEP Operating
Partnerships are sometimes collectively referred to herein as the "KMEP
Partnerships" and the KMEP Partnerships and the SF Operating Partnership are
referred to as the "Operating Partnerships." In connection with the closing of
the Transaction, the partnership agreement of the SF Operating Partnership will
be amended and restated to be substantially similar to the partnership
agreements for the KMEP Operating Partnerships, except with respect to
provisions relating to the Special LP Interest. The following discussion is
qualified in its entirety by reference to the partnership agreements for KMEP,
the KMEP Partnerships and the SF Operating Partnership. With regard to
allocations of taxable income and taxable loss, see "Material Federal Income Tax
Considerations."
    
 
ORGANIZATION AND DURATION
 
    KMEP, each of the KMEP Partnerships and the SF Operating Partnership are
Delaware limited partnerships.
 
    The KM General Partner is the general partner of KMEP and each of the KMEP
Partnerships. The KM General Partner owns an approximate 1% direct interest as
general partner in KMEP and each of the KMEP Partnerships and an approximate 1%
indirect economic interest in each of the KMEP Partnerships through its general
partner interest in KMEP. In addition, the KM General Partner is entitled to
receive quarterly cash incentive distributions from KMEP, which increase based
on the amount of quarterly cash distributions paid to holders of KMEP Common
Units. The KMEP Common Units represent all of the remaining partnership
interests in KMEP. KMEP owns an approximate 99% limited partner interest in each
of the KMEP Partnerships. After giving effect to the Transaction and the Special
Distribution, OLP-D will own a 99.5% general partner interest and the SF General
Partner will own the .5% Special LP Interest in the SF Operating Partnership.
 
    Unless liquidated or dissolved at an earlier time, under the terms of the
KMEP Partnership Agreement, KMEP and each of the KMEP Partnerships will dissolve
on December 31, 2082. Unless liquidated or dissolved at an earlier time, under
the terms of the SF Operating Partnership Agreement, the SF Operating
Partnership will dissolve on December 31, 2082.
 
RECENT AMENDMENTS TO THE KMEP PARTNERSHIP AGREEMENT
 
   
    On January 14, 1998, KMEP amended and restated the KMEP Partnership
Agreement, to be effective as of February 14, 1997 (the date of the acquisition
of the KM General Partner by KMI). The amended and restated partnership
agreement restated the KMEP Partnership Agreement to incorporate prior
amendments and made the following technical amendments (which were adopted by
the KM General Partner pursuant to its limited power of attorney, see
"--Amendment of KMEP Partnership Agreement and Other Agreements").
    
 
   
    Section 3.1 of the KMEP Partnership Agreement (the purpose and business
clause) was amended to provide that KMEP may conduct any business that may be
lawfully conducted by a limited partnership organized pursuant to the Delaware
Act. Previously, the KMEP Partnership Agreement provided that KMEP could engage
in any business permitted by the Omnibus Agreement, dated as of August 6, 1992,
among Enron Corp., KMEP, OLP-A and the KM General Partner (formerly Enron
Liquids Pipeline Company), as amended (the "Omnibus Agreement"). The Omnibus
Agreement provided that KMEP could conduct any business that may be lawfully
conducted by a limited partnership organized pursuant to
    
 
                                      106
<PAGE>
the Delaware Act, subject to Enron's right of first refusal with respect to
certain activities. As a result of KMI's acquisition of the KM General Partner,
the right of first refusal in favor of Enron is no longer applicable and the
amendment merely clarifies the permitted partnership purposes.
 
    At the time that KMEP was initially formed it had only one operating
partnership, OLP-A, but was permitted, pursuant to Section 3.1(b) "to engage
directly in, or to enter into any partnership, joint venture or similar
arrangement to engage in, any business activity" permitted by the KMEP
Partnership Agreement. In connection with the acquisition of the Cora Terminal
in September 1993, KMEP created OLP-B and amended the definition of "Operating
Partnership" to include any partnerships, joint ventures or other entities
formed by KMEP in connection with the conduct by KMEP of activities permitted by
the terms of Section 3.1. The definition of Operating Partnership has been
amended to clarify that the term "Operating Partnership" includes any
partnerships, joint ventures or other entities formed OR ACQUIRED by KMEP. The
KM General Partner believes that this change is consistent with the intent of
Section 3.1(b) of the KMEP Partnership Agreement.
 
PURPOSE
 
    The purpose of KMEP under the KMEP Partnership Agreement is to serve as the
limited partner in the Operating Partnerships and to conduct any other business
that may be lawfully conducted by a limited partnership organized pursuant to
the Delaware Act.
 
POWER OF ATTORNEY
 
    Each limited partner, and each person who acquires a KMEP Common Unit from a
prior holder and executes and delivers a transfer application with respect to
such KMEP Common Unit, grants to the KM General Partner and, if a liquidator has
been appointed, the liquidator, a power of attorney to, among other things, (i)
execute and file certain documents required in connection with the
qualification, continuance or dissolution of KMEP or the amendment of the KMEP
Partnership Agreement in accordance with the terms of the KMEP Partnership
Agreement and (ii) make consents and waivers contained in the KMEP Partnership
Agreement.
 
RESTRICTIONS ON AUTHORITY OF THE KM GENERAL PARTNER
 
    The authority of the KM General Partner is limited in certain respects under
the KMEP Partnership Agreement. The KM General Partner is prohibited, without
the prior approval of holders of record of a majority of the outstanding KMEP
Common Units from, among other things, selling or exchanging all or
substantially all of KMEP's assets in a single transaction or a series of
related transactions (including by way of merger, consolidation or other
combination) or approving on behalf of KMEP the sale, exchange or other
disposition of all or substantially all of the assets of KMEP, provided that
KMEP may mortgage, pledge, hypothecate or grant a security interest in all or
substantially all of KMEP's assets without such approval. KMEP may sell all or
substantially all of its assets pursuant to a foreclosure or other realization
upon the foregoing encumbrances without such approval. Except as provided in the
KMEP Partnership Agreement and generally described under "Comparison of Common
Unit Holders' Rights" and "--Amendment of KMEP Partnership Agreement and Other
Agreements," any amendment to a provision of the KMEP Partnership Agreement
generally will require the approval of the holders of at least 66 2/3% of the
KMEP Common Units. The KM General Partner's ability to sell or otherwise dispose
of KMEP's assets will also be restricted in that substantially all of the
property, plant and equipment of KMEP are pledged to secure indebtedness of the
KMEP Partnerships and substantially all of the property, plant and equipment of
the SF Operating Partnership are pledged to secure indebtedness of the SF
Operating Partnership.
 
    In general, the KM General Partner may not take any action, or refuse to
take any reasonable action, without the consent of the holders of at least a
majority of each class of outstanding units of KMEP,
 
                                      107
<PAGE>
including the consent of at least a majority of the outstanding KMEP Common
Units (other than KMEP Common Units owned by the KM General Partner and its
affiliates), the effect of which would be to cause KMEP to be treated as an
association taxable as a corporation or otherwise taxed as an entity for federal
income tax purposes.
 
WITHDRAWAL OR REMOVAL OF THE KM GENERAL PARTNER
 
    The KM General Partner has agreed not to voluntarily withdraw as general
partner of KMEP prior to January 1, 2003 (with limited exceptions described
below) without the approval of at least a majority of the outstanding KMEP
Common Units (excluding for purposes of such determination KMEP Common Units
held by the KM General Partner and its affiliates) and furnishing an opinion of
counsel that such withdrawal will not cause KMEP to be treated as an association
taxable as a corporation or otherwise taxed as an entity for federal income tax
purposes or result in the loss of the limited liability of any limited partner.
On or after January 1, 2003, the KM General Partner may withdraw as general
partner by giving 90 days' written notice (without first obtaining approval from
the holders of KMEP Common Units), and such withdrawal will not constitute a
breach of the KMEP Partnership Agreement. If an opinion of counsel cannot be
obtained to the effect that (following the selection of a successor) the KM
General Partner's withdrawal would not result in the loss of limited liability
of the holders of KMEP Common Units or cause KMEP to be treated as an
association taxable as a corporation or otherwise taxed as an entity for federal
income tax purposes, KMEP will be dissolved after such withdrawal.
Notwithstanding the foregoing, the KM General Partner may withdraw without
approval the holders of KMEP Common Units upon 90 days' notice to the limited
partners if more than 50% of the outstanding KMEP Common Units (other than those
held by the withdrawing KM General Partner and its affiliates) are held or
controlled by one person and its affiliates. In addition, the KMEP Partnership
Agreement does not restrict KMI's ability to sell directly or indirectly, all or
any portion of the capital stock of the KM General Partner to a third party
without the approval of the holders of KMEP Common Units.
 
    The KM General Partner may not be removed unless such removal is approved by
the vote of the holders of not less than 66 2/3% of the outstanding KMEP Common
Units (excluding KMEP Common Units held by the KM General Partner and its
affiliates) provided that certain other conditions are satisfied. Any such
removal is subject to the approval of the successor general partner by the same
vote and receipt of an opinion of counsel that such removal and the approval of
a successor will not result in the loss of limited liability of any limited
partner or cause KMEP to be treated as an association taxable as a corporation
or otherwise taxed as an entity for federal income tax purposes.
 
    Removal or withdrawal of the KM General Partner as the general partner of
KMEP also constitutes removal or withdrawal, as the case may be, of the KM
General Partner as the general partner of the KMEP Partnerships.
 
    In the event of withdrawal of the KM General Partner where such withdrawal
violates the KMEP Partnership Agreement or removal of the KM General Partner by
the limited partners under circumstances where cause exists, a successor general
partner will have the option to acquire the general partner interest of the
departing General Partner (the "Departing Partner") in KMEP and the KMEP
Partnerships for a cash payment equal to the fair market value of such interest.
Under all other circumstances where the KM General Partner withdraws or is
removed by the limited partners, the Departing Partner will have the option to
require the successor general partner to acquire such general partner interest
of the Departing Partner for such amount. In each case such fair market value
will be determined by agreement between the Departing Partner and the successor
general partner, or if no agreement is reached, by an independent investment
banking firm or other independent expert selected by the Departing Partner and
the successor general partner (or if no expert can be agreed upon, by the expert
chosen by agreement of the expert selected by each of them). In addition, KMEP
would also be required to reimburse the Departing Partner for all amounts due
the Departing Partner, including without limitation all employee related
liabilities,
 
                                      108
<PAGE>
including severance liabilities, incurred in connection with the termination of
the employees employed by the Departing Partner for the benefit of KMEP.
 
    If the above-described option is not exercised by either the Departing
Partner or the successor general partner, as applicable, the Departing Partner's
general partner interest in KMEP will be converted into KMEP Common Units equal
to the fair market value of such interest as determined by an investment banking
firm or other independent expert selected in the manner described in the
preceding paragraph.
 
    The KM General Partner may transfer all, but not less than all, of its
general partner interest in KMEP without the approval of the limited partners to
one of its affiliates or upon its merger or consolidation into another entity or
the transfer of all or substantially all of its assets to another entity,
provided in either case that such entity assumes the rights and duties of the KM
General Partner, agrees to be bound by the provisions of the KMEP Partnership
Agreement and furnishes an opinion of counsel that such transfer would not
result in the loss of the limited liability of any limited partner or cause KMEP
to be treated as an association taxable as a corporation or otherwise cause KMEP
to be subject to entity level taxation for federal income tax purposes. In the
case of any other transfer of the general partner interest in KMEP, in addition
to the foregoing requirements, the approval of at least a majority of the KMEP
Common Units is required, excluding for such purposes those interests held by
the KM General Partner and its affiliates.
 
    Upon the withdrawal or removal of the KM General Partner, KMEP will be
dissolved, wound up and liquidated, unless such withdrawal or removal takes
place following the approval of a successor general partner or unless within 180
days after such withdrawal or removal a majority of the holders of KMEP Common
Units agree in writing to continue the business of KMEP and to the appointment
of a successor general partner. See "--Termination and Dissolution."
 
ANTI-TAKEOVER AND RESTRICTED VOTING RIGHT PROVISIONS
 
    The KMEP Partnership Agreement contains certain provisions that are intended
to discourage a person or group from attempting to remove the KM General
Partner, as general partner, or otherwise change the management of KMEP. If any
person or group other than the KM General Partner and its affiliates acquires
beneficial ownership of 20% or more of the KMEP Common Units, such person or
group loses any and all voting rights with respect to all of the KMEP Common
Units beneficially owned or held by such person.
 
TRANSFER AGENT AND REGISTRAR
 
    DUTIES.  First Chicago Trust Company of New York is the registrar and
transfer agent (the "Transfer Agent") for the KMEP Common Units and receives a
fee from KMEP for serving in such capacities. All fees charged by the Transfer
Agent for transfers of KMEP Common Units are borne by KMEP and not by the
holders of KMEP Common Units, except that fees similar to those customarily paid
by holders of securities for surety bond premiums to replace lost or stolen
certificates, taxes or other governmental charges, special charges for services
requested by a holder of a KMEP Common Unit and other similar fees or charges
will be borne by the affected holder. There will be no charge to holders for
disbursements of KMEP cash distributions. KMEP will indemnify the Transfer
Agent, its agents and each of their respective shareholders, directors, officers
and employees against all claims and losses that may arise out of acts performed
or omitted in respect of its activities as such, except for any liability due to
any negligence, gross negligence, bad faith or intentional misconduct of the
indemnified person or entity.
 
    RESIGNATION OR REMOVAL.  The Transfer Agent may at any time resign, by
notice to KMEP, or be removed by KMEP, such resignation or removal to become
effective upon the appointment by the KM General Partner of a successor transfer
agent and registrar and its acceptance of such appointment. If no successor has
been appointed and accepted such appointment within 30 days after notice of such
 
                                      109
<PAGE>
resignation or removal, the KM General Partner is authorized to act as the
transfer agent and registrar until a successor is appointed.
 
TRANSFER OF KMEP COMMON UNITS; STATUS AS LIMITED PARTNER OR ASSIGNEE
 
    Until a KMEP Common Unit has been transferred on the books of KMEP, KMEP and
the Transfer Agent, notwithstanding any notice to the contrary, may treat the
record holder thereof as the absolute owner for all purposes, except as
otherwise required by law or stock exchange regulation. Any transfers of a KMEP
Common Unit will not be recorded by the Transfer Agent or recognized by KMEP
unless the transferee executes and delivers a Transfer Application (set forth on
the reverse side of the certificate representing KMEP Common Units). By
executing and delivering the Transfer Application, the transferee of KMEP Common
Units (i) becomes the record holder of such KMEP Common Units and shall
constitute an assignee until admitted to KMEP as a substitute limited partner,
(ii) automatically requests admission as a substituted limited partner in the
Partnership, (iii) agrees to be bound by the terms and conditions of and is
deemed to have executed the KMEP Partnership Agreement, (iv) represents that
such transferee has capacity, power and authority to enter into the KMEP
Partnership Agreement, (v) grants powers of attorney to the KM General Partner
and any liquidator of KMEP as specified in the KMEP Partnership Agreement and
(vi) makes the consents and waivers contained in the KMEP Partnership Agreement.
An assignee, pending its admission as a substituted limited partner in KMEP, is
entitled to an interest in KMEP equivalent to that of a limited partner with
respect to the right to share in allocations and distributions from KMEP,
including liquidating distributions. The KM General Partner will vote, and
exercise other powers attributable to, KMEP Common Units owned by an assignee
who has not become a substituted limited partner at the written direction of
such Assignee. See "--Meetings; Voting."
 
    An assignee will become a substituted limited partner of KMEP in respect of
the transferred KMEP Common Units upon the consent of the KM General Partner and
the recordation of the name of the assignee on the books and records of KMEP.
Such consent may be withheld in the sole discretion of the KM General Partner.
KMEP Common Units are securities and are transferable according to the laws
governing transfers of securities. In addition to other rights acquired upon
transfer, the transferor gives the transferee the right to request admission as
a substituted limited partner in KMEP in respect of the transferred KMEP Common
Units. A purchaser or transferee of KMEP Common Units who does not execute and
deliver a Transfer Application obtains only (a) the right to transfer the KMEP
Common Units to a purchaser or other transferee and (b) the right to transfer
the right to seek admission as a substituted limited partner in KMEP with
respect to the transferred KMEP Common Units. Thus, a purchaser or transferee of
KMEP Common Units who does not execute and deliver a Transfer Application will
not receive cash distributions unless the KMEP Common Units are held in a
nominee or street name account and the nominee or broker has executed and
delivered a Transfer Application with respect to such KMEP Common Units and may
not receive certain federal income tax information or reports furnished to
record holders of KMEP Common Units. The transferor of KMEP Common Units will
have a duty to provide such transferee with all information that may be
necessary to obtain registration of the transfer of the KMEP Common Units, but
the transferee agrees, by acceptance of the certificate representing KMEP Common
Units, that the transferor will not have a duty to see to the execution of the
Transfer Application by the transferee and will have no liability or
responsibility if such transferee neglects or chooses not to execute and forward
the Transfer Application.
 
    Holders of KMEP Common Units may hold their KMEP Common Units in nominee
accounts, provided that the broker (or other nominee) executes and delivers a
Transfer Application. KMEP will be entitled to treat the nominee holder of a
KMEP Common Unit as the absolute owner thereof, and the beneficial owner's
rights will be limited solely to those that it has against the nominee holder as
a result of or by reason of any understanding or agreement between such
beneficial owner and nominee holder.
 
                                      110
<PAGE>
NON-CITIZEN ASSIGNEES; REDEMPTION
 
    If KMEP is or becomes subject to federal, state or local laws or regulations
that, in the reasonable determination of the KM General Partner, provides for
the cancellation or forfeiture of any property in which KMEP has an interest
because of the nationality, citizenship or other related status of any limited
partner or assignee, KMEP may redeem the KMEP Common Units held by such limited
partner or assignee at their Average Fair Market Price. In order to avoid any
such cancellation or forfeiture, the KM General Partner may require each record
holder or assignee to furnish information about the holder's nationality,
citizenship, residency or related status. If the record holder fails to furnish
such information within 30 days after a request for such information, or if the
KM General Partner determines on the basis of the information furnished by such
holder in response to the request that the cancellation or forfeiture of any
property in which KMEP has an interest may occur, the KM General Partner may be
substituted as the limited partner for such record holder, who will then be
treated as a non-citizen assignee ("Non-citizen Assignee"), and the KM General
Partner will have the right to redeem the KMEP Common Units held by such record
holder as described above. The KMEP Partnership Agreement sets forth the rights
of such record holder or assignee upon redemption. Pending such redemption or in
lieu thereof, the KM General Partner may change the status of any such limited
partner or assignee to that of a Non-citizen Assignee. Further, a Non-citizen
Assignee (unlike an assignee who is not a substitute limited partner) does not
have the right to direct the vote regarding such Non-citizen Assignee's KMEP
Common Units and may not receive distributions in kind upon liquidation of KMEP.
See "--Transfer of KMEP Common Units; Status as Limited Partner or Assignee."
 
    As used in this Joint Proxy Statement/Prospectus, (i) "Average Fair Market
Price" of a limited partner interest as of any date means the average of the
daily End of Day Price (as hereinafter defined) for the 20 consecutive Unit
Transaction Days (as hereinafter defined) immediately prior to such date; (ii)
"End of Day Price" for any day means the last sale price on such day, regular
way, or in case no such sale takes place on such day, the average of the closing
bid and asked prices on such day, 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 principal national securities exchange on
which the limited partner interests of such class are listed or admitted to
trading or, if the limited partner interests of such class are not listed or
admitted to trading on any national securities exchange, the last quoted sale
price on such day, or, if not so quoted, the average of the high bid and low
asked prices on such day in the over-the-counter market, as reported by the
NASDAQ or such other system then in use, or if on any such day the limited
partner interests of such class are not quoted by any such organization, the
average of the closing bid and asked prices on such day as furnished by a
professional market maker making a market in the limited partner interests of
such class selected by the Board of Directors of the KM General Partner, or if
on any such day no market maker is making a market in such limited partner
interests, the fair value of such limited partner interests on such day as
determined reasonably and in good faith by the Board of Directors of the KM
General Partner; and (iii) "Unit Transaction Day" means a day on which the
principal national securities exchange on which such limited partner interests
are listed or admitted to trading is open for the transaction of business or, if
the limited partner interests of such class are not listed or admitted to
trading on any national securities exchange, a day on which banking institutions
in New York City generally are open.
 
ISSUANCE OF ADDITIONAL SECURITIES
 
    KMEP'S ISSUANCE OF SECURITIES.  The KMEP Partnership Agreement does not
restrict the ability of the KM General Partner to issue additional limited or
general partner interests and authorizes the KM General Partner to cause KMEP to
issue additional securities of KMEP for such consideration and on such terms and
conditions as shall be established by the KM General Partner in its sole
discretion without the approval of any limited partners. In accordance with
Delaware law and the provisions of the KMEP
 
                                      111
<PAGE>
Partnership Agreement, the KM General Partner may issue additional partnership
interests which, in its sole discretion, may have special voting rights to which
the KMEP Common Units are not entitled.
 
    LIMITED PRE-EMPTIVE RIGHT OF KM GENERAL PARTNER.  The KM General Partner has
the right, which it may from time to time assign in whole or in part to any of
its affiliates, to purchase KMEP Common Units or other equity securities of KMEP
from KMEP whenever, and on the same terms that, KMEP issues such securities to
persons other than the KM General Partner and its affiliates, to the extent
necessary to maintain the percentage interest of the KM General Partner and its
affiliates in KMEP to that which existed immediately prior to each such
issuance. The KM General Partner has waived its pre-emptive rights with respect
to the Transaction, but not with respect to any other or further transaction.
 
LIMITED CALL RIGHT
 
    If at any time not more than 20% of the issued and outstanding limited
partner interests of any class are held by persons other than the KM General
Partner and its affiliates, the KM General Partner will have the right, which it
may assign and transfer to any of its affiliates or to KMEP, to purchase all,
but not less than all, of the outstanding limited partner interests of such
class held by such non-affiliated persons, as of a record date to be selected by
the KM General Partner, on at least 10 but not more than 60 days' notice. The
purchase price in the event of such purchase shall be the greater of (i) the
Average Fair Market Price of limited partner interests of such class as of the
date five days prior to the mailing of written notice of its election to
purchase limited partner interests of such class and (ii) the highest cash price
paid by the KM General Partner or any of its affiliates for any limited partner
interests of such class purchased within the 90 days preceding the date the KM
General Partner mails notice of its election to purchase such KMEP Common Units.
 
AMENDMENT OF KMEP PARTNERSHIP AGREEMENT AND OTHER AGREEMENTS
 
    Amendments to the KMEP Partnership Agreement may be proposed only by or with
the consent of the KM General Partner. In order to adopt a proposed amendment,
the KM General Partner is required to seek written approval of the holders of
the number of KMEP Common Units required to approve such amendment or call a
meeting of the limited partners to consider and vote upon the proposed
amendment, except as described below. Proposed amendments (other than those
described below) must be approved by holders of at least 66 2/3% of the
outstanding KMEP Common Units, except that no amendment may be made which would
(i) enlarge the obligations of any limited partner, without its consent, (ii)
enlarge the obligations of the KM General Partner, without its consent, which
may be given or withheld in its sole discretion, (iii) restrict in any way any
action by or rights of the KM General Partner as set forth in the KMEP
Partnership Agreement, (iv) modify the amounts distributable, reimbursable or
otherwise payable by KMEP to the KM General Partner, (v) change the term of KMEP
or (vi) give any person the right to dissolve KMEP other than the KM General
Partner's right to dissolve KMEP with the approval of a majority of the
outstanding KMEP Common Units or change such right of the KM General Partner in
any way.
 
    Amendments to the partnership agreements of the KMEP Partnerships may be
proposed by or with the consent of the KM General Partner. Proposed amendments
(other than those described below) require the approval of KMEP, as the limited
partner of the KMEP Partnerships. In addition, amendments to the SF Operating
Partnership Agreement may be adopted by OLP-D without the consent of the holder
of the special limited partner interest.
 
    The KM General Partner may make amendments to the KMEP Partnership Agreement
without the approval of any limited partner or assignee of KMEP to reflect (i) a
change in the name of KMEP, the location of the principal place of business of
KMEP, the registered agent or the registered office of the partnership, (ii)
admission, substitution, withdrawal or removal of partners in accordance with
the KMEP Partnership Agreement, (iii) a change that, in the sole discretion of
the KM General Partner, is reasonable and necessary or appropriate to qualify or
continue the qualification of KMEP as a partnership in which
 
                                      112
<PAGE>
the limited partners have limited liability or that is necessary or advisable in
the opinion of the KM General Partner to ensure that KMEP will not be treated as
an association taxable as a corporation or otherwise subject to taxation as an
entity for federal income tax purposes, (iv) an amendment that is necessary, in
the opinion of counsel to KMEP, to prevent KMEP or the KM General Partner or
their respective directors or officers from in any manner being subjected to the
provisions of the Investment Company Act of 1940, as amended, the Investment
Advisors Act of 1940, as amended, or "plan asset" regulations adopted under the
Employee Retirement Income Security Act of 1974, as amended, whether or not
substantially similar to plan asset regulations currently applied or proposed by
the United States Department of Labor, (v) subject to the limitations on the
issuance of additional KMEP Common Units or other limited or general partner
interests described above, an amendment that in the sole discretion of the KM
General Partner is necessary or desirable in connection with the authorization
of additional limited or general partner interests, (vi) any amendment expressly
permitted in the KMEP Partnership Agreement to be made by the KM General Partner
acting alone, (vii) an amendment effected, necessitated or contemplated by a
merger agreement that has been approved pursuant to the terms of the KMEP
Partnership Agreement and (viii) any other amendments substantially similar to
the foregoing.
 
    In addition, the KM General Partner may make amendments to the KMEP
Partnership Agreement without such consent if such amendments (i) do not
adversely affect the limited partners in any material respect, (ii) are
necessary or desirable to satisfy any requirements, conditions or guidelines
contained in any opinion, directive, ruling or regulation of any federal or
state agency or judicial authority or contained in any federal or state statute,
(iii) are necessary or desirable to facilitate the trading of the KMEP Common
Units or to comply with any rule, regulation, guideline or requirement of any
securities exchange on which the KMEP Common Units are or will be listed for
trading, compliance with any of which the KM General Partner deems to be in the
best interests of KMEP and the holders of KMEP Common Units or (iv) are required
to effect the intent of, or as contemplated by, the KMEP Partnership Agreement.
 
    The KM General Partner will not be required to obtain an opinion of counsel
as to the tax consequences or the possible effect on limited liability of
amendments described in the two immediately preceding paragraphs. No other
amendments to the KMEP Partnership Agreement will become effective without the
approval of at least 95% of the KMEP Common Units unless KMEP obtains an opinion
of counsel to the effect that such amendment will not cause KMEP to be treated
as an association taxable as a corporation or otherwise cause KMEP to be subject
to entity level taxation for federal income tax purposes and will not affect the
limited liability of any limited partner in KMEP or the limited partner of the
Operating Partnerships.
 
    Any amendment that materially and adversely affects the rights or
preferences of any type or class of limited partner interests in relation to
other types or classes of limited partner interests or the general partner
interests will require the approval of at least 66 2/3% of the type or class of
limited partner interests so affected.
 
MANAGEMENT
 
    GENERAL.  The KM General Partner will manage and operate the activities of
KMEP, and the KM General Partner's activities will be limited to such management
and operation. Holders of KMEP Common Units will not direct or participate in
the management or operations of KMEP, any of the KMEP Partnerships or the SF
Operating Partnership. See "--Limited Liability." The KM General Partner will
owe a fiduciary duty to the holders of KMEP Common Units. See "Risk
Factors--Risk Associated with KMEP Partnership Agreement and State Partnership
Law." Notwithstanding any limitation on obligations or duties, the KM General
Partner will be liable, as the general partner of KMEP, for all the debts of
KMEP (to the extent not paid by KMEP), except to the extent that indebtedness
incurred by KMEP is made specifically non-recourse to the KM General Partner.
See "The Purchase Agreement--Indemnification--Santa Fe."
 
                                      113
<PAGE>
    KMEP does not currently have any directors, officers or employees. As is
commonly the case with publicly traded limited partnerships, KMEP does not
currently contemplate that it will directly employ any of the persons
responsible for managing or operating KMEP's business or for providing it with
services, but will instead reimburse the KM General Partner or its affiliates
for the services of such persons. See "--Reimbursement of Expenses." The KM
General Partner's employees are not represented by any labor unions, and they
are not covered by any collective bargaining agreements.
 
    REIMBURSEMENT OF EXPENSES.  The KM General Partner will receive no
management fee or similar compensation in conjunction with its management of
KMEP (other than cash distributions). See "Comparison of Common Unit Holders'
Rights" and "--Cash Distribution Policy." However, the KM General Partner is
entitled pursuant to KMEP Partnership Agreement to reimbursement on a monthly
basis, or such other basis as the KM General Partner may determine in its sole
discretion, for all direct and indirect expenses it incurs or payments it makes
on behalf of KMEP and all other necessary or appropriate expenses allocable to
KMEP or otherwise reasonably incurred by the KM General Partner in connection
with operating KMEP's business. The KMEP Partnership Agreement provides that the
KM General Partner shall determine the fees and expenses that are allocable to
KMEP in any reasonable manner determined by the KM General Partner in its sole
discretion. The reimbursement for such costs and expenses will be in addition to
any reimbursement to the KM General Partner and its affiliates as a result of
the indemnification provisions of KMEP Partnership Agreement. See
"--Indemnification."
 
    INDEMNIFICATION.  The KMEP Partnership Agreement provides that KMEP will
indemnify the KM General Partner, any Departing Partner and any person who is or
was an officer or director of the KM General Partner or any Departing Partner,
to the fullest extent permitted by law, and may indemnify, to the extent deemed
advisable by the KM General Partner, to the fullest extent permitted by law, any
person who is or was an affiliate of the KM General Partner or any Departing
Partner, any person who is or was an officer, director, employee, partner, agent
or trustee of the KM General Partner, any Departing Partner or any such
affiliate, or any person who is or was serving at the request of the KM General
Partner or any affiliate of the KM General Partner or any Departing Partner as
an officer, director, employee, partner, agent, or trustee of another person
("Indemnitees") from and against any and all losses, claims, damages,
liabilities (joint or several) expenses (including, without limitation, legal
fees and expenses), judgments, fines, penalties, interest, settlement and other
amounts arising from any and all claims, demands, actions, suits or proceedings,
whether civil, criminal, administrative or investigative, in which any
Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, by reason of its status as (i) the KM General Partner, a Departing
Partner or affiliate of either, (ii) an officer, director, employee, partner,
agent or trustee of the KM General Partner, any Departing Partner or affiliate
of either or (iii) a person serving at the request of KMEP in another entity in
a similar capacity, provided that in each case the Indemnitee acted in good
faith and in a manner which the Indemnitee believed to be in or not opposed to
the best interests of KMEP and, with respect to any criminal proceeding, had no
reasonable cause to believe its conduct was unlawful. Any indemnification under
the KMEP Partnership Agreement will only be paid out of the assets of KMEP, and
the KM General Partner will not be personally liable for, or have any obligation
to contribute or loan funds or assets to KMEP to enable it to effectuate, such
indemnification. KMEP is authorized to purchase (or to reimburse the KM General
Partner or its affiliates for the cost of) insurance, purchased on behalf of the
KM General Partner and such other persons as the KM General Partner determines,
against liabilities asserted against and expenses incurred by such persons in
connection with KMEP's activities, whether or not KMEP would have the power to
indemnify such person against such liabilities under the provisions described
above.
 
    CONFLICTS AND AUDIT COMMITTEE.  One or more directors who are neither
officers nor employees of the KM General Partner or any of its affiliates will
serve as a committee of the Board of Directors of the KM General Partner (the
"Conflicts and Audit Committee") and will, at the request of the KM General
Partner, review specific matters as to which the KM General Partner believes
there may be a conflict of interest in order to determine if the resolution of
such conflict proposed by the KM General Partner is fair
 
                                      114
<PAGE>
and reasonable to KMEP. The Conflicts and Audit Committee will only review
matters at the request of the KM General Partner, which has sole discretion to
determine which matters to submit to such Committee. Any matters approved by the
Conflicts and Audit Committee will be conclusively deemed to be fair and
reasonable to KMEP, approved by all partners of KMEP and not a breach by the KM
General Partner of the KMEP Partnership Agreement or any duties it may owe to
KMEP. Additionally, it is possible that such procedure in itself may constitute
a conflict of interest.
 
MEETINGS; VOTING
 
    Holders of KMEP Common Units or assignees who are record holders of KMEP
Common Units on the record date set pursuant to the KMEP Partnership Agreement
will be entitled to notice of, and to vote at, meetings of limited partners of
KMEP and to act with respect to matters as to which approvals may be solicited.
With respect to voting rights attributable to KMEP Common Units that are owned
by assignees who have not yet been admitted as limited partners, the KM General
Partner will be deemed to be the limited partner with respect thereto and will,
in exercising the voting rights in respect of such KMEP Common Units on any
matter, vote such KMEP Common Units at the written direction of such record
holder. If a proxy is not returned on behalf of the KMEP Common Unit record
holder, such KMEP Common Units will not be voted (except that, in the case of
KMEP Common Units held by the KM General Partner on behalf of Non-citizen
Assignees, the KM General Partner will distribute the votes in respect of such
KMEP Common Units in the same ratios as the votes of limited partners in respect
of other KMEP Common Units are cast). When a proxy is returned properly
executed, the KMEP Common Units represented thereby will be voted in accordance
with the indicated instructions. If no instructions have been specified on the
properly executed and returned proxy, the KMEP Common Units represented thereby
will be voted "FOR" the approval of the matters to be presented. KMEP Common
Units held by the KM General Partner on behalf of Non-citizen Assignees, as
defined pursuant to the KMEP Partnership Agreement, shall be voted by the KM
General Partner in the same ratios as the votes of the limited partners with
respect to the matter presented to the holders of KMEP Common Units.
 
    Any action that is required or permitted to be taken by the limited partners
may be taken either at a meeting of the limited partners or without a meeting if
consents in writing setting forth the action so taken are signed by holders of
such number of limited partner interests as would be necessary to authorize or
take such action at a meeting of the limited partners. Meetings of the limited
partners of KMEP may be called by the KM General Partner or by limited partners
owning at least 20% of the outstanding KMEP Common Units of the class for which
a meeting is proposed. Limited partners may vote either in person or by proxy at
meetings. Two-thirds (or a majority, if that is the vote required to take action
at the meeting in question) of the outstanding limited partner interests of the
class for which a meeting is to be held (excluding, if such are excluded from
such vote, limited partner interests held by the KM General Partner and its
affiliates) represented in person or by proxy will constitute a quorum at a
meeting of limited partners of KMEP. Except for any proposal for removal of the
KM General Partner or certain amendments to the KMEP Partnership Agreement
described above, substantially all matters submitted for a vote are determined
by the affirmative vote, in person or by proxy, of holders of a majority of the
outstanding limited partner interests.
 
    Each record holder of a KMEP Common Unit has a vote according to such record
holder's percentage interest in KMEP, although additional limited partner
interests having special voting rights could be issued by the KM General
Partner. See "--Issuance of Additional Securities." However, KMEP Common Units
owned beneficially by any person or group (other than the KM General Partner and
its affiliates) that own beneficially 20% or more of all KMEP Common Units may
not be voted on any matter and will not be considered to be outstanding when
sending notices of a meeting of limited partners, calculating required votes,
determining the presence of a quorum or for other similar KMEP partnership
purposes. The KMEP Partnership Agreement provides that KMEP Common Units held in
nominee or street name accounts will be voted by the broker (or other nominee)
pursuant to the instruction of the
 
                                      115
<PAGE>
beneficial owner, unless the arrangement between the beneficial owner and such
holder's nominee provides otherwise.
 
    Any notice, demand, request, report or proxy materials required or permitted
to be given or made to record holders of KMEP Common Units (whether or not such
record holder has been admitted as a limited partner) under the terms of the
KMEP Partnership Agreement will be delivered to the record holder by KMEP or by
the Transfer Agent at the request of KMEP.
 
LIMITED LIABILITY
 
    Except as described below, KMEP Common Units are fully paid, and holders of
KMEP Common Units will not be required to make additional contributions to KMEP.
 
    Assuming that a limited partner does not participate in the control of the
business of KMEP, within the meaning of the Delaware Act, and that such partner
otherwise acts in conformity with the provisions of the KMEP Partnership
Agreement, such partner's liability under the Delaware Act will be limited,
subject to certain possible exceptions, generally to the amount of capital such
partner is obligated to contribute to KMEP in respect of such holder's KMEP
Common Units plus such holder's share of any undistributed profits and assets of
KMEP. However, if it were determined that the right or exercise of the right by
the limited partners as a group to remove or replace the KM General Partner, to
approve certain amendments to the KMEP Partnership Agreement or to take other
action pursuant to the KMEP Partnership Agreement constituted "participation in
the control" of KMEP's business for the purposes of the Delaware Act, then the
limited partners could be held personally liable for KMEP's obligations under
the laws of the State of Delaware to the same extent as the KM General Partner.
Under the Delaware Act, a limited partnership may not make a distribution to a
partner to the extent that at the time of the distribution, after giving effect
to the distribution, all liabilities of the partnership, other than liabilities
to partners on account of their partnership interests and nonrecourse
liabilities, exceed the fair value of the assets of the limited partnership. For
the purpose of determining the fair value of the assets of a limited
partnership, the Delaware Act provides that the fair value of property subject
to nonrecourse liability shall be included in the assets of the limited
partnership only to the extent that the fair value of that property exceeds that
nonrecourse liability. The Delaware Act provides that a limited partner who
receives such a distribution and knew at the time of the distribution that the
distribution was in violation of the Delaware Act shall be liable to the limited
partnership for the amount of the distribution for three years from the date of
the distribution. Under the Delaware Act, an assignee who becomes a substituted
limited partner of a limited partnership is liable for the obligations of the
assignor to make contributions to the partnership, except the assignee is not
obligated for liabilities unknown to such assignee at the time the assignee
became a limited partner and which could not be ascertained from the partnership
agreement.
 
    KMEP is organized under the laws of Delaware and currently conducts business
in Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Missouri, Nebraska,
Texas and Wyoming and upon completion of the Transaction will also conduct
business in Arizona, California, New Mexico, Nevada and Oregon. Maintenance of
limited liability will require compliance with legal requirements in such
jurisdictions in which KMEP conducts business, including qualifying the
Operating Partnerships to do business therein. Limitations on the liability of
limited partners for the obligations of a limited partnership have not been
clearly established in many jurisdictions. If it were determined that KMEP was,
by virtue of its limited partner interest in the Operating Partnerships or
otherwise, conducting business in any state without compliance with the
applicable limited partnership statute, or that the right or exercise of the
right by the limited partners as a group to remove or replace the KM General
Partner, to approve certain amendments to the KMEP Partnership Agreement, or to
take other action pursuant to the KMEP Partnership Agreement constituted
"participation in the control" of KMEP's business for the purposes of the
statues of any relevant jurisdiction, then the limited partners could be held
personally liable for KMEP's obligations under the law of such jurisdiction to
the same extent as the KM General Partner. KMEP will operate in such manner as
the KM General Partner deems reasonable and necessary or appropriate to preserve
the limited liability of holders of KMEP Common Units.
 
                                      116
<PAGE>
BOOKS AND REPORTS
 
    The KM General Partner is required to keep appropriate books of the business
at the principal offices of KMEP. The books will be maintained for both tax and
financial reporting purposes on an accrual basis. The fiscal year of KMEP is the
calendar year.
 
    As soon as practicable, but in no event later than 120 days after the close
of each fiscal year, the KM General Partner will furnish each record holder of a
KMEP Common Unit (as of a record date selected by the KM General Partner) with
an annual report containing audited financial statements of KMEP for the past
fiscal year, prepared in accordance with generally accepted accounting
principles. As soon as practicable, but in no event later than 90 days after the
close of each calendar quarter (except the fourth quarter), the KM General
Partner will furnish each record holder of KMEP Common Units upon request a
report containing unaudited financial statements of KMEP and such other
information as may be required by law.
 
    The KM General Partner will use all reasonable efforts to furnish each
record holder of a KMEP Common Unit information reasonably required for tax
reporting purposes within 90 days after the close of each taxable year. Such
information is expected to be furnished in a summary form so that certain
complex calculations normally required of partners can be avoided. The KM
General Partner's ability to furnish such summary information to holders of KMEP
Common Units will depend on the cooperation of such holders of KMEP Common Units
in supplying certain information to the KM General Partner. Every holder of a
KMEP Common Unit (without regard to whether such holder supplies such
information to the KM General Partner) will receive information to assist in
determining such holder's federal and state tax liability and filing such
holder's federal and state income tax returns.
 
RIGHT TO INSPECT KMEP PARTNERSHIP BOOKS AND RECORDS
 
    The KMEP Partnership Agreement provides that a limited partner can, for a
purpose reasonably related to such limited partner's interest as a limited
partner, upon reasonable demand and at such partner's own expense, have
furnished to him (i) a current list of the name and last known address of each
partner, (ii) a copy of KMEP's tax returns, (iii) information as to the amount
of cash, and a description and statement of the agreed value of any other
property or services contributed or to be contributed by each partner and the
date on which each became a partner, (iv) copies of the KMEP Partnership
Agreement, the certificate of limited partnership of KMEP, amendments thereto
and powers of attorney pursuant to which the same have been executed, (v)
information regarding the status of KMEP's business and financial condition and
(vi) such other information regarding the affairs of KMEP as is just and
reasonable. The KM General Partner may, and intends to, keep confidential from
the limited partners trade secrets or other information the disclosure of which
the KM General Partner believes in good faith is not in the best interests of
KMEP or which KMEP is required by law or by agreements with third parties to
keep confidential.
 
TERMINATION AND DISSOLUTION
 
    KMEP will continue until December 31, 2082, unless sooner terminated
pursuant to the KMEP Partnership Agreement. KMEP will be dissolved upon (i) the
election of the KM General Partner to dissolve KMEP, if approved by a majority
of the KMEP Common Units, (ii) the sale of all or substantially all of the
assets and properties of KMEP and its operating partnerships, (iii) the
bankruptcy or dissolution of the KM General Partner or (iv) the withdrawal or
removal of the KM General Partner or any other event that results in its ceasing
to be the KM General Partner (other than by reason of a transfer in accordance
with the KMEP Partnership Agreement or withdrawal or removal following approval
of a successor), provided that KMEP will not be dissolved upon an event
described in clause (iv) if within 90 days after such event the partners agree
in writing to continue the business of KMEP and to the appointment, effective as
of the date of such event, of a successor general partner. Upon a dissolution
pursuant to clause (iii) or (iv), at least a majority of the KMEP Common Units
may also elect, within
 
                                      117
<PAGE>
certain time limitations, to reconstitute KMEP and continue its business on the
same terms and conditions set forth in the KMEP Partnership Agreement by forming
a new limited partnership on terms identical to those set forth in the KMEP
Partnership Agreement and having as a general partner an entity approved by at
least a majority of the KMEP Common Units, subject to receipt by KMEP of an
opinion of counsel that the exercise of such right will not result in the loss
of the limited liability of holders of KMEP Common Units or cause KMEP or the
reconstituted limited partnership to be treated as an association taxable as a
corporation or otherwise subject to taxation as an entity for federal income tax
purposes.
 
REGISTRATION RIGHTS
 
    Pursuant to the terms of the KMEP Partnership Agreement and subject to
certain limitations described therein, KMEP has agreed to register for resale
under the Securities Act of 1933 and applicable state securities laws any KMEP
Common Units (or other securities of KMEP) proposed to be sold by the KM General
Partner (or its affiliates) if an exemption from such registration requirements
is not otherwise available for such proposed transaction. KMEP is obligated to
pay all expenses incidental to such registration, excluding underwriting
discounts and commissions.
 
CASH DISTRIBUTION POLICY
 
    GENERAL.  A principal objective of KMEP is to generate cash from KMEP
operations and to distribute Available Cash to its partners in the manner
described herein. "Available Cash" generally means, with respect to any calendar
quarter, the sum of all of the cash received by KMEP from all sources, less all
of its cash disbursements and net additions to reserves. For purposes of cash
distributions to holders of KMEP Common Units, the term Available Cash excludes
the amount paid to the SF General Partner in respect of its Special LP Interest
in the SF Operating Partnership, which amount will equal 0.5% of the total cash
distributions made each quarter by the SF Operating Partnership to its partners.
 
    The KM General Partner's decisions regarding amounts to be placed in or
released from reserves may have a direct impact on the amount of Available Cash.
This is because increases and decreases in reserves are taken into account in
computing Available Cash. The KM General Partner may, in its reasonable
discretion (subject to certain limits), determine the amounts to be placed in or
released from reserves each quarter.
 
    Cash distributions will be characterized as either distributions of Cash
from Operations or Cash from Interim Capital Transactions. This distinction
affects the amounts distributed to holders of KMEP Common Units relative to the
KM General Partner. See "--Quarterly Distributions of Available Cash--
Distributions of Cash from Operations" and "--Quarterly Distributions of
Available Cash--Distributions of Cash from Interim Capital Transactions."
 
    "Cash from Operations" generally refers to the cash balance of KMEP on the
date KMEP commenced operations, plus all cash generated by the operations of
KMEP's business, after deducting related cash expenditures, reserves, debt
service and certain other items.
 
    "Cash from Interim Capital Transactions" will generally be generated only by
borrowings, sales of debt and equity securities and sales or other dispositions
of assets for cash (other than inventory, accounts receivable and other current
assets and assets disposed of in the ordinary course of business).
 
    To avoid the difficulty of trying to determine whether Available Cash
distributed by KMEP is Cash from Operations or Cash from Interim Capital
Transactions, all Available Cash distributed by KMEP from any source will be
treated as Cash from Operations until the sum of all Available Cash distributed
as Cash from Operations equals the cumulative amount of Cash from Operations
actually generated from the date KMEP commenced operations through the end of
the calendar quarter prior to such distribution. Any excess Available Cash
(irrespective of its source) will be deemed to be Cash from Interim Capital
Transactions and distributed accordingly.
 
                                      118
<PAGE>
    If Cash from Interim Capital Transactions is distributed in respect of each
KMEP Common Unit in an aggregate amount per KMEP Common Unit equal to $11.00 per
KMEP Common Unit, (the initial public offering price of the KMEP Common Units
adjusted to give effect to the 2-for-1 split of KMEP Common Units effective
October 1, 1997) (the "Initial KMEP Common Unit Price"), the distinction between
Cash from Operations and Cash from Interim Capital Transactions will cease, and
both types of Available Cash will be treated as Cash from Operations. The KM
General Partner does not anticipate that there will be significant amounts of
Cash from Interim Capital Transactions distributed.
 
    The discussion below indicates the percentages of cash distributions
required to be made to the KM General Partner and the holders of KMEP Common
Units. In the following general discussion of how Available Cash is distributed,
references to Available Cash, unless otherwise stated, mean Available Cash that
constitutes Cash from Operations.
 
    QUARTERLY DISTRIBUTIONS OF AVAILABLE CASH.  KMEP will make distributions to
its partners with respect to each calendar quarter prior to liquidation in an
amount equal to 100% of its Available Cash for such quarter.
 
    DISTRIBUTIONS OF CASH FROM OPERATIONS.  Distributions by KMEP of Available
Cash constituting Cash from Operations with respect to any quarter will be made
in the following manner:
 
        FIRST, 98% to the holders of KMEP Common Units pro rata and 2% to the KM
    General Partner until the holders of KMEP Common Units have received a total
    of $0.3025 per KMEP Common Unit for such quarter in respect of each KMEP
    Common Unit (the "First Target Distribution"); and
 
        SECOND, 85% of any such Available Cash then remaining to the holders of
    KMEP Common Units pro rata and 15% to the KM General Partner until the
    holders of KMEP Common Units have received a total of $0.3575 per KMEP
    Common Unit for such quarter in respect of each KMEP Common Unit (the
    "Second Target Distribution");
 
        THIRD, 75% of any such Available Cash then remaining to all holders of
    KMEP Common Units pro rata and 25% to the KM General Partner until the
    holders of KMEP Common Units have received a total of $0.4675 per KMEP
    Common Unit for such quarter in respect of each KMEP Common Unit (the "Third
    Target Distribution"); and
 
        FOURTH, 50% of any such Available Cash then remaining to all holders of
    KMEP Common Units pro rata and 50% to the KM General Partner.
 
    In addition, if the First, Second and Third Target Distribution levels are
reduced to zero, as described below under "--Quarterly Distributions of
Available Cash--Adjustment of Target Distribution Levels," all remaining
Available Cash will be distributed as Cash from Operations, 50% to the holders
of KMEP Common Units pro rata and 50% to the KM General Partner. These
provisions are inapplicable upon the dissolution and liquidation of KMEP.
 
    DISTRIBUTIONS OF CASH FROM INTERIM CAPITAL TRANSACTIONS.  Distributions on
any date by KMEP of Available Cash that constitutes Cash from Interim Capital
Transactions will be distributed 98% to all holders of KMEP Common Units pro
rata and 2% to the KM General Partner until KMEP shall have distributed in
respect of each KMEP Common Unit Available Cash constituting Cash from Interim
Capital Transactions in an aggregate amount per KMEP Common Unit equal to the
Initial KMEP Common Unit Price.
 
    As Cash from Interim Capital Transaction is distributed, it is treated as if
it were a repayment of the initial public offering price. To reflect such
repayment, the First, Second and Third Target Distribution levels will be
adjusted downward by multiplying each amount by a fraction, the numerator of
which is the Unrecovered Initial KMEP Common Unit Price immediately after giving
effect to such repayment and the denominator of which is the Unrecovered Initial
KMEP Common Unit Price, immediately prior to giving
 
                                      119
<PAGE>
effect to such repayment. "Unrecovered Initial KMEP Common Unit Price" includes
the amount by which the Initial KMEP Common Unit Price exceeds the aggregate
distribution of Cash from Interim Capital Transactions per KMEP Common Unit.
 
    When "Payback of Initial KMEP Common Unit Price" is achieved, I.E., when the
Unrecovered Initial KMEP Common Unit Price is zero, then in effect the First,
Second and Third Target Distribution levels each will have been reduced to zero.
Thereafter all distributions of Available Cash from all sources will be treated
as if they were Cash from Operations and Available Cash will be distributed 50%
to all holders of KMEP Common Units pro rata and 50% to the KM General Partner.
 
    ADJUSTMENT OF TARGET DISTRIBUTION LEVELS.  The First, Second and Third
Target Distribution levels will be proportionately adjusted upward or downward,
as appropriate, in the event of any combination or subdivision of KMEP Common
Units (whether effected by a distribution payable in KMEP Common Units or
otherwise) but not by reason of the issuance of additional KMEP Common Units for
cash or property. For example, in connection with KMEP's two-for-one split of
the KMEP Common Units on October 1, 1997, the First, Second and third Target
Distribution levels were each reduced to 50% of its initial level. See
"--Quarterly Distributions of Available Cash--Distributions of Cash from
Operations."
 
    In addition, if a distribution is made of Available Cash constituting Cash
from Interim Capital Transactions, the First, Second and Third Target
Distribution levels will be adjusted downward proportionately, by multiplying
each such amount, as the same may have been previously adjusted, by a fraction,
the numerator of which is the Unrecovered Initial KMEP Common Unit Price
immediately after giving effect to such distribution and the denominator of
which is the Unrecovered Initial KMEP Common Unit Price immediately prior to
such distribution. For example, assuming the Unrecovered Initial KMEP Common
Unit Price is $11.00 per KMEP Common Unit and if Cash from Interim Capital
Transactions of $5.50 per KMEP Common Unit is distributed to holders of KMEP
Common Units (assuming no prior adjustments), then the amount of the First,
Second and Third Target Distribution levels would each be reduced to 50% of its
initial level. If and when the Unrecovered Initial KMEP Common Unit Price is
zero, the First, Second and Third Target Distribution levels each will have been
reduced to zero, and the KM General Partner's share of distributions of
Available Cash will increase, in general, to 50% of all distributions of
Available Cash.
 
    The First, Second and Third Target Distribution levels may also be adjusted
if legislation is enacted which causes KMEP to become taxable as a corporation
or otherwise subjects KMEP to taxation as an entity for federal income tax
purposes. In such event, the First, Second, and Third Target Distribution levels
for each quarter thereafter would be reduced to an amount equal to the product
of (i) each of the First, Second and Third Target Distribution levels multiplied
by (ii) one minus the sum of (x) the maximum marginal federal income tax rate to
which KMEP is subject as an entity plus (y) any increase that results from such
legislation in the effective overall state and local income tax rate to which
KMEP is subject as an entity for the taxable year in which such quarter occurs
(after taking into account the benefit of any deduction allowable for federal
income tax purposes with respect to the payment of state and local income
taxes). For example, assuming KMEP was not previously subject to state and local
income tax, if KMEP were to become taxable as an entity for federal income tax
purposes and KMEP became subject to a maximum marginal federal, and effective
state and local, income tax rate of 38%, then each of the Target Distribution
levels, would be reduced to 62% of the amount thereof immediately prior to such
adjustment.
 
LIQUIDATION AND DISTRIBUTION OF PROCEEDS
 
    Upon dissolution of KMEP, unless KMEP is reconstituted and continued as a
new limited partnership, the person authorized to wind up the affairs of KMEP
(the "Liquidator") will, acting with all of the powers of the KM General Partner
that such Liquidator deems necessary or desirable in its good faith judgment in
connection therewith, liquidate KMEP's assets and apply the proceeds of the
liquidation as follows: (i) first towards the payment of all creditors of KMEP
and the creation of a reserve for contingent liabilities and
 
                                      120
<PAGE>
(ii) then to all partners in accordance with the positive balances in their
respective capital accounts. Under certain circumstances and subject to certain
limitations, the Liquidator may defer liquidation or distribution of KMEP's
assets for a reasonable period of time and/or distribute assets to partners in
kind if it determines that a sale would be impractical or would cause undue loss
to the partners.
 
    Generally, any gain will be allocated between the holders of KMEP Common
Units and the KM General Partner in a manner that approximates their sharing
ratios in the various Target Distribution levels. Holders of KMEP Common Units
and the KM General Partner will share in the remainder of KMEP's assets in
proportion to their respective capital account balances in KMEP.
 
    Any loss or unrealized loss will be allocated to the KM General Partner and
the holders of KMEP Common Units: FIRST, in proportion to the positive balances
in such partners' capital accounts until all such balances are reduced to zero;
and THEREAFTER, to the KM General Partner.
 
                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS
 
   
GENERAL
    
 
   
    In the opinion of Morrison & Hecker, except as to such matters as to which
such discussion states that Morrison & Hecker is unable to opine and except as
to such discussion as to which Mayer, Brown & Platt is rendering its opinion,
with respect to which Morrison & Hecker does not express an opinion, the
following discussion accurately describes the material federal income tax
consequences of the Transaction and the ownership and disposition of KMEP Common
Units. In the opinion of Mayer, Brown & Platt, the discussion in the third
paragraph under "--Legal Opinions and Advice" and the discussion under "--Tax
Consequences of the Exchange and Distributions" accurately describes the
material federal income tax consequences of the Transaction to Santa Fe and the
holders of Santa Fe Common Units. There can be no assurance that the IRS will
take a similar view of such consequences. Moreover, no party to the Transaction
has or will request a ruling from the IRS as to the tax treatment of the
Transaction, or as to any other matter addressed in this discussion. Moreover,
the IRS has announced that it will not grant rulings regarding the federal
income tax treatment of transfers to certain classes of partnerships in which
KMEP would be included.
    
 
   
    The following discussion is based upon current provisions of the Code,
existing and proposed regulations thereunder and current administrative rulings
and court decisions, including modifications made by the Taxpayer Relief Act of
1997 (the "1997 Act"), all as in effect on the date hereof, the facts set forth
in the Joint Proxy Statement/Prospectus and related documents and factual
representations made by the KM General Partner and the SF General Partner. Such
discussion is also based on the assumptions that the Transaction and the
operation of KMEP and the Operating Partnerships, will be in accordance with
this Joint Proxy Statement/Prospectus and the relevant partnership agreements.
Such discussion is subject both to the accuracy of such facts and assumptions
and the continued applicability of such legislative, administrative and judicial
authorities, all of which authorities are subject to change, possibly
retroactively. Subsequent changes in such authorities may cause the tax
consequences to vary substantially from the consequences described below, and
any such change may be retroactively applied in a manner that could adversely
affect a holder of KMEP Common Units or Santa Fe Common Units.
    
 
   
    The discussion below is directed primarily to the typical holder of KMEP
Common Units or Santa Fe Common Units who is an individual and a United States
citizen or resident (as determined for federal income tax purposes). Except as
specifically noted, the discussion does not address all of the federal income
tax consequences that may be relevant (i) to a holder in light of such holder's
particular circumstances, (ii) to a holder that is a partnership, corporation,
trust or estate or (iii) to holders subject to special rules, such as certain
financial institutions, tax-exempt entities, foreign corporations, non-resident
alien individuals, insurance companies, dealers in securities, or traders in
securities who elect to mark to market and persons holding the KMEP Common Units
or Santa Fe Common Units as part of a "straddle," "hedge" or "conversion
transaction." Moreover, the effect of any applicable state, local or foreign tax
laws
    
 
                                      121
<PAGE>
   
is not discussed. The discussion deals only with KMEP Common Units and Santa Fe
Common Units held as "capital assets" within the meaning of Section 1221 of the
Code. Accordingly, each holder of KMEP Common Units or Santa Fe Common Units is
strongly urged to consult a tax advisor, prior to executing and delivering a
proxy, with specific reference to the effect of such holder's particular facts
and circumstances on the matters discussed herein.
    
 
    The federal income tax consequences of the Transaction and the federal
income tax treatment of holders of KMEP Common Units depend in some instances on
determinations of fact and interpretations of complex provisions of federal
income tax laws for which no clear precedent or authority may be available. The
KM General Partner, in determining KMEP's taxable income, allocations, basis
adjustments and asset valuations, must make determinations in its capacity as
the general partner of KMEP that could affect the holders of KMEP Common Units.
Where appropriate, the KM General Partner will act upon the advice of legal
counsel or other professional tax advisors in making such interpretations and
determinations.
 
   
    If the Transaction is consummated, KMEP will be the continuing entity for
state law purposes. The KM General Partner will also treat KMEP as the
continuing entity for federal income tax purposes. See "--Tax Consequences of
the Transaction--Surviving Partnership for Tax Purposes." Any reference to KMEP
below is to the continuing publicly traded entity, KMEP, and, where the context
requires, the Operating Partnerships after the Transaction.
    
 
    For purposes of this discussion, the term "Exchange" will refer to the
transfer of substantially all of the limited partner interest in the SF
Operating Partnership (the "SF Operating Partnership LP Interest") by Santa Fe
to KMEP (which will then contribute such interest to OLP-D) in exchange for the
right to receive 1.39 KMEP Common Units for each outstanding Santa Fe Common
Unit (which will result in the issuance to the public holders of Santa Fe Common
Units of an aggregate of approximately 15.3 million KMEP Common Units and the
issuance to the SF General Partner of an aggregate of approximately 11.3 million
KMEP Common Units), and the term "Distributions" will refer to the Liquidation
Distributions and the Fractional Unit Payments.
 
   
LEGAL OPINIONS AND ADVICE
    
 
   
    Morrison & Hecker has rendered its opinion to KMEP to the effect that:
    
 
   
        (a) KMEP and the Operating Partnerships are and will continue to be
    classified as partnerships for federal income tax purposes and will not be
    classified as associations taxable as corporations, assuming that the
    factual representations set forth in "--General Features of Partnership
    Taxation-- Partnership Status" are adhered to by such partnerships.
    
 
        (b) A KMEP Common Unit holder who continues to hold such KMEP Common
    Units will not realize any gain or loss because of the Transaction,
    including the contribution of the SF Operating Partnership LP Interest to
    KMEP in exchange for the right to receive KMEP Common Units and the
    Distribution of KMEP Common Units to holders of Santa Fe Common Units.
 
   
        (c) Each person who (i) acquires beneficial ownership of KMEP Common
    Units pursuant to the Transaction and who has executed and delivered a
    Letter of Transmittal and either has been admitted or is pending admission
    to KMEP as an additional limited partner or (ii) acquired beneficial
    ownership of KMEP Common Units pursuant to the Transaction and whose KMEP
    Common Units are held by a nominee (so long as such person has the right to
    direct the nominee in the exercise of all substantive rights attendant to
    the ownership of such KMEP Common Units) will be treated as a partner of
    KMEP for federal income tax purposes.
    
 
                                      122
<PAGE>
   
    The following are material federal income tax issues associated with the
ownership of KMEP Common Units and the operation of KMEP with respect to which
Morrison & Hecker is unable to opine:
    
 
   
         1. Because counsel is not a valuation expert and does not opine on
    valuation issues, whether the appraised valuations of assets and allocation
    of such amounts (the "Book-Tax Disparity") between and among tangible assets
    and intangible assets (and the resulting net Curative Allocations) will be
    sustained if challenged by the IRS. See "Tax Consequences of Holding KMEP
    Common Units-- Capital Accounts, Valuation of Assets and Curative
    Allocations under Section 704(c)" and "--Fungibility Issues Arising From
    Intangibles."
    
 
   
         2. Because of the lack of applicable legal authority, whether certain
    procedures utilized by KMEP in administering the Section 754 election and
    the resulting Section 743(b) adjustments to any KMEP Common Unit holder's
    basis in their KMEP Common Units will be sustained if challenged by the IRS.
    See "--Tax Treatment of Operations--Section 754 Election."
    
 
   
    Mayer, Brown & Platt has rendered its opinion to Santa Fe to the effect
that: (i) subject to the uncertainty involving the treatment of the Fractional
Unit Payments as described under "--Tax Consequences of the Exchange and
Distribution--Disguised Sale Rules," Santa Fe will not recognize gain or loss as
a result of the transfer of limited partner interests in the SF Operating
Partnership to KMEP in exchange for rights to receive KMEP Common Units or as a
result of such KMEP Common Units being distributed to, and received by, Santa Fe
Common Unit holders; (ii) subject to the uncertainty involving the treatment of
the Fractional Unit Payments, Santa Fe Common Unit holders will not recognize
any gain or loss (A) on the transfer of limited partner interests in the SF
Operating Partnership by Santa Fe to KMEP in exchange for rights to receive KMEP
Common Units, (B) upon the receipt of the right to receive KMEP Common Units
pursuant to the liquidation of Santa Fe or the receipt of such KMEP Common
Units, (C) upon the receipt of a Fractional Unit Payment from KMEP, except to
the extent that the Fractional Unit Payment received by any such holder exceeds
such holder's tax basis in KMEP Common Units, or (D) otherwise as a result of
the Transaction; (iii) the tax basis of the KMEP Common Units received by a
Santa Fe Common Unit holder will be equal to the adjusted tax basis of such
holder's Santa Fe Common Units, reduced, but not below zero, by the amount of
the Fractional Unit Payment received, if any; and (iv) based upon a
representation of the SF General Partner that there has not been a constructive
termination of Santa Fe for federal income tax purposes since 1988, the holding
period of the KMEP Common Units in the hands of the Santa Fe Common Unit holders
will be deemed to have commenced no later than January 1, 1989, except to the
extent the value of the SF Operating Partnership is attributable to Section 751
assets other than depreciation recapture (e.g. unrealized receivables, inventory
items and capital improvements not held by the SF Operating Partnership for more
than 12 months), in which case the holding period of the KMEP Common Units
received by a Santa Fe Common Unit holder attributable to such Section 751
assets will begin on the day following the date of the Transaction. The SF
General Partner believes that an insignificant portion of the value of the SF
Operating Partnership is attributable to such items. See "--Tax Consequences of
the Exchange and Distributions."
    
 
   
    A more detailed discussion of these items is contained in the applicable
sections below.
    
 
   
    The opinions of Morrison & Hecker and Mayer, Brown & Platt are based on
certain representations of KMEP, the KM General Partner, Santa Fe and the SF
General Partner. The opinions of Morrison & Hecker are based upon the opinion of
Mayer, Brown & Platt regarding the classification of Santa Fe and the SF
Operating Partnership as partnerships and the opinions of Mayer, Brown & Platt
are based upon the opinion of Morrison & Hecker regarding the classification of
KMEP as a partnership. In addition, such opinions are based upon existing
provisions of the Code and the Regulations, existing administrative rulings and
procedures of the IRS and existing court decisions. There can be no assurances
that any of such authorities will not be changed in the future, which change
could be retroactively applied. Such opinions represent only Morrison & Hecker's
and Mayer, Brown & Platt's best legal judgments as to the particular issues and
are not binding on the IRS or the courts. Consummation of the Transaction is
conditioned upon
    
 
                                      123
<PAGE>
   
receipt of a confirmation of these and certain other opinions as of the Closing
Date. The Purchase Agreement provides that this condition to Closing may be
waived by the parties. No such waiver is anticipated. However, if this condition
were to be waived, KMEP and Santa Fe would recirculate this Joint Proxy
Statement/Prospectus, appropriately revised to disclose the waiver of this
condition and any other relevant facts, including risks to investors, and
resolicit proxies from Santa Fe Common Unit holders and KMEP Common Unit
holders.
    
 
SURVIVING PARTNERSHIP FOR TAX PURPOSES
 
   
    KMEP AS SURVIVOR.  KMEP will be the surviving partnership for state law
purposes. There is no direct precedent which specifically addresses a factual
situation such as the Transaction to provide guidance as to whether KMEP or
Santa Fe should be treated as the surviving partnership for tax purposes. It is
possible that the IRS could view the Transaction as a merger of KMEP and Santa
Fe. For federal income tax purposes, the surviving partnership in a merger is
the partnership whose members own 50 percent or more of both the capital and
profits of the resulting partnership. The KM General Partner has prepared
projections of profit allocations based on the KMEP Partnership Agreement and
current expected operations that indicate neither the former Santa Fe Common
Unit holders nor the pre-Transaction KMEP Common Unit holders will have more
than 50% of both the capital and profits of KMEP after the Transaction.
Therefore, the KM General Partner intends to treat KMEP as the surviving
partnership for tax purposes. The KM General Partner believes this is
appropriate because: (a) KMEP is the continuing partnership for state law
purposes; (b) there is no merger in form or substance; and (c) if the
Transaction were treated, in substance, as a merger, the former Santa Fe Common
Unit holders will not own more than 50% of the profits interest of the resulting
KMEP. However, if the Transaction were treated as a merger for federal income
tax purposes and the former Santa Fe Common Unit holders were deemed to have
acquired more than 50% of the capital and profits of KMEP, Santa Fe would be
deemed to have survived for federal income tax purposes, notwithstanding the
fact that KMEP is the surviving partnership for state law purposes.
    
 
   
    The determination of which partnership is deemed to survive the Transaction
is relevant to a number of issues. Assuming that KMEP is the surviving
partnership, the pre-Transaction KMEP Common Unit holders who continue to hold
KMEP Common Units will not be deemed to have participated in an exchange as a
result of the Transaction. If, however, Santa Fe were the surviving partnership,
the holding period of the KMEP Common Units held by former Santa Fe Common Unit
holders would include the holding period of their Santa Fe Common Units. Also,
pre-Transaction holders of KMEP Common Units would have a new holding period for
the portion of their KMEP Common Units attributable to assets that did not
constitute either capital assets or Section 1231 assets (generally depreciable
assets and real property used in a business with a holding period of more than
12 months). The KM General Partner does not believe that this bifurcation of
holding period with respect to the pre-Transaction KMEP Common Unit holders
would be material.
    
 
   
    The surviving partnership's elections, fiscal year, depreciable lives for
its assets and Curative Allocation periods will continue until any future
constructive termination resulting from a sale or exchange of more than 50% of
the capital and profits of such partnership. Since both KMEP and Santa Fe have
adopted similar elections, fiscal years, depreciable lives and tax allocation
methodologies, if Santa Fe were deemed to be the surviving partnership for
federal income tax purposes, the KM General Partner does not believe there would
be a material adverse impact to a pre-Transaction KMEP Common Unit holder.
However, in such case, a pre-Transaction KMEP Common Unit holder would have a
bifurcation of holding period as previously discussed.
    
 
   
    ADMINISTRATIVE MATTERS FOLLOWING THE TRANSACTION.  KMEP (as the continuing
partnership for state law purposes) will use its employer identification number,
tax shelter registration number and accounting elections following the
Transaction. The provisions of the Code dealing with employer identification
numbers, tax shelter registration numbers and accounting elections are contained
in sections of the Code
    
 
                                      124
<PAGE>
other than those dealing with the formation and operation of partnerships. It
would appear, therefore, that the identification numbers and accounting
elections of the continuing entity for state law purposes should be used by the
partnership that continues for tax purposes. Based on this analysis, KMEP will
continue to use KMEP's employer identification number, tax shelter registration
number and accounting elections. Holders of KMEP Common Units are advised that
there is no direct authority on this point and, accordingly, if Santa Fe were
deemed to be the surviving partnership for federal income tax purposes, the IRS
may seek to impose penalties on KMEP for failure to use correct employer
identification numbers and on both KMEP and the KMEP Common Unit holders for the
use of an incorrect tax shelter registration number. Also, KMEP may use methods
of accounting that the IRS may assert to have been improperly elected.
 
    The following discussion assumes that KMEP, and not Santa Fe, will be the
surviving partnership for federal income tax purposes.
 
   
TAX CONSEQUENCES OF THE EXCHANGE AND DISTRIBUTION
    
 
   
    GENERAL.  The federal income tax consequences described herein are dependent
upon both KMEP and Santa Fe being classified as partnerships for federal income
tax purposes. While Morrison & Hecker has opined that KMEP is classified as a
partnership for federal income tax purposes and Mayer, Brown & Platt has opined
that Santa Fe is classified as a partnership for federal income tax purposes, no
rulings have been requested from the IRS, and no assurance can be given that the
IRS will not successfully assert that either KMEP or Santa Fe is not properly
classified as a partnership for federal income tax purposes.
    
 
   
    In addition, such opinions are based upon representations of the KM General
Partner and the SF General Partner, respectively, with respect to the nature of
the income of KMEP and Santa Fe, which is relevant to a determination of whether
their income qualifies for the Natural Resource Exception pursuant to Section
7704 of the Code. See "--General Features of Partnership Taxation--Partnership
Status." If either KMEP or Santa Fe failed to qualify for the Natural Resource
Exception, it would be taxable as a corporation since it is publicly traded. The
treatment of various types of income is not clear in all respects; thus no
assurances can be given that the IRS will not take the position that KMEP or
Santa Fe fails to qualify for the Natural Resource Exception, or that a court
would not sustain such determination.
    
 
    If KMEP were treated as a corporation for federal income tax purposes, and
Santa Fe were treated as a partnership, the Transaction would be taxable to
Santa Fe and the Santa Fe Common Unit holders with the resulting gain increasing
the basis of the Santa Fe Common Units and the KMEP Common Units received by
such holders. If Santa Fe were treated as a corporation for federal income tax
purposes, the Transaction would be taxable to Santa Fe and the liquidation of
Santa Fe would result in the receipt of KMEP Common Units by Santa Fe Common
Unit holders in a taxable exchange. As a consequence of either result, Santa Fe
and the Santa Fe Common Unit holders would have material federal income tax
liabilities, which would exceed cash distributions from Santa Fe and KMEP.
 
    The following discussion assumes that both KMEP and Santa Fe are properly
treated as partnerships for federal income tax purposes and not otherwise
taxable as corporations.
 
   
    PARTNERSHIP CONTRIBUTIONS AND DISTRIBUTIONS.  Section 721 of the Code
provides that, as a general rule, no gain or loss is recognized by a partnership
or by any of its partners upon a contribution of property to a partnership in
exchange for an interest in the partnership. In addition, Section 731 of the
Code provides that, as a general rule, neither a partnership nor a partner
recognizes gain or loss on the distribution by the partnership of property,
other than money, to a partner. However, the tax free treatment under Section
721 of the Code does not apply to a contribution of property to a partnership
that is classified as an "investment company" under the Code, to a contribution
of property that is treated as a "disguised sale" of the contributed property
under the Code, or to the extent that the contributing partners receive
consideration other than an interest in the partnership. Further, depending upon
the circumstances, a
    
 
                                      125
<PAGE>
   
partner's deemed relief from liabilities, either in connection with a
contribution to a partnership or a distribution from a partnership or a
repayment of part or all of such liabilities, could cause the partner to
recognize taxable gain on a contribution or distribution that would otherwise
qualify for tax free treatment under Section 721 or Section 731 of the Code. Tax
free treatment under Section 731 of the Code also does not apply to the extent
that any money (which, for this purpose, includes certain marketable securities)
distributed by the partnership exceeds the adjusted tax basis of the partner's
interest in the partnership immediately before the distribution. It should also
be noted that the IRS has announced that it will not grant rulings regarding the
federal income tax treatment of transfers of assets to certain classes of
partnerships in which KMEP would be included.
    
 
   
    INVESTMENT COMPANY RULES.  If KMEP is considered an "investment company", as
defined in the Code and Treasury Regulations, the Exchange will not be tax free
under Section 721 of the Code. The Treasury Regulations and the Code provide
that a transfer will be treated as having been made to an investment company if
the transfer results in a diversification of the interests of the transferor,
and the transferee is (a) a regulated investment company ("RIC"), (b) a real
estate investment trust ("REIT"), or (c) a partnership more than 80% of the
value of whose assets are held for investment and are stock or securities
(including for this purpose, money, options, forward contracts, derivatives and
certain other assets, but excluding for this purpose, interests in partnerships
that are not publicly traded partnerships) or interests in RICs or REITs.
Although the transfer by Santa Fe to KMEP will result in the diversification of
the interests of Santa Fe and the Santa Fe Common Unit holders, KMEP is not a
REIT or a RIC, and, based upon certain representations of the KM General
Partner, no significant portion of its assets or the assets of the Operating
Partnerships is comprised of stocks or securities (as defined above) or
interests in RICs or REITs. Consequently, KMEP will not be considered an
investment company at the time of the exchange.
    
 
    DISGUISED SALE RULES.  The Exchange also would not be tax free to Santa Fe
and the Santa Fe Common Unit holders to the extent that it is treated as a
"disguised sale" of the property under the Code or Treasury Regulations. The
Code and the Treasury Regulations thereunder (the "Disguised Sale Rules")
generally provide that a partner's contribution of property to a partnership and
a simultaneous or subsequent transfer of money or other consideration (including
the assumption by the partnership of a liability of the partner or taking of
property by the partnership subject to a liability) from the partnership to the
partner will be presumed to be a sale, in whole or in part, of such property by
the partner to the partnership. Except for the possible treatment of the
Fractional Unit Payment discussed below, there is no cash or other property
being received by Santa Fe and Santa Fe is not being relieved of any
liabilities.
 
   
    There is a possibility that the IRS may seek to ignore the form of the
Transaction and take the position that the Santa Fe Common Unit holders' receipt
of the Fractional Unit Payments from KMEP in partial exchange for their Santa Fe
Common Units should be treated under the Disguised Sale Rules as a payment of
money by KMEP to Santa Fe in exchange for a portion of the limited partner
interest in the SF Operating Partnership, followed by a distribution of the
Fractional Unit Payment to Santa Fe Common Unit holders receiving such cash. If
the IRS were to take this position and prevail, Santa Fe would recognize gain to
the extent that the total amount of the Fractional Unit Payments exceeds Santa
Fe's adjusted tax basis in the portion of the SF Operating Partnership limited
partner interests considered to be sold to KMEP under the Disguised Sale Rules.
The taxable gain would be allocated ratably to Santa Fe Common Unit holders, and
a Santa Fe Common Unit holder could be allocated a share of such gain, even
though such holder will not receive a Fractional Unit Payment.
    
 
   
    Although there is no definitive authority on this point, it is more likely
than not that the form of the Transaction will be respected and that the
Fractional Unit Payment will be treated as a cash distribution from KMEP to the
Santa Fe Common Unit holders, rather than as a payment to Santa Fe as part of a
disguised sale. Even if the IRS recharacterized the Fractional Unit Payments as
payment received in a disguised sale, the SF General Partner believes that the
gain that would be recognized by any Santa Fe Common Unit holder would not be
significant.
    
 
                                      126
<PAGE>
   
    RELIEF FROM LIABILITIES/DEEMED CASH DISTRIBUTION.  Under the applicable
provisions of the Code (See "--Tax Consequences of KMEP Common Unit
Ownership--Basis of KMEP Common Units"), a partner includes in the tax basis for
such partner's partnership interest the share of the partnership's liabilities,
determined in accordance with the Treasury Regulations under Section 752 of the
Code. The partner also includes in the tax basis for such partnership interest
any capital contributions that such partner actually made to the partnership and
such partner's allocable share of all partnership income and gains, less the
amount of all distributions that such partner receives from the partnership and
such partner's allocable share of all partnership losses. For purposes of these
rules, if a partner's share of the partnership liabilities is reduced for any
reason, the partner is deemed to have received a cash distribution equal to the
amount of such reduction. The partner will recognize gain as a result of this
deemed cash distribution if, and to the extent that, the deemed cash
distribution exceeds its adjusted tax basis for its partnership interest. Upon
the Exchange, Santa Fe will not be relieved of liabilities in excess of its tax
basis in the limited partner interests in the SF Operating Partnership such that
gain would be recognized on the Exchange. Upon the Liquidation Distribution, no
Santa Fe Common Unit holder will be relieved of any liabilities such that gain
would be recognized because there are no liabilities currently allocated to the
Santa Fe Common Unit holders.
    
 
   
    DISTRIBUTION OF MONEY FROM PARTNERSHIPS--THE DISTRIBUTIONS.  Under Section
731 of the Code, a partner will recognize gain as a result of a distribution
from a partnership if the partnership distributes money and the amount of money
received by the partner exceeds such partner's adjusted tax basis in the
partnership interest prior to the distribution. The amount of gain is limited to
this excess. Generally, for purposes of Section 731, a distribution of readily
marketable securities is treated as a distribution of cash.
    
 
   
    Because the KMEP Common Units are tradeable, the Liquidation Distribution
would be considered a distribution of cash under this general rule. However, a
regulatory exception provides that a distribution of marketable securities will
not be treated as a distribution of cash if (i) such securities are acquired by
the partnership in a non-recognition transaction, (ii) the value of any
marketable securities transferred to KMEP in such transaction is less than 20%
of the value of all assets transferred to KMEP and (iii) the partnership
distributes the securities within five years. Because (i) as discussed above,
the Exchange will constitute a non-recognition transaction under Section 721(a)
of the Code, (ii) the SF Operating Partnership limited partner interests
transferred to KMEP in the Exchange are not readily marketable and (iii) Santa
Fe will immediately distribute the rights to KMEP Common Units pursuant to the
Liquidation Distributions, the Liquidation Distribution will not be treated as a
distribution of cash to a Santa Fe Common Unit holder.
    
 
   
    As discussed above, it is more likely than not that the Fractional Unit
Payments will be treated as a cash payment by KMEP to the Santa Fe Common Unit
holders at the time they become KMEP Common Unit holders pursuant to the
Transaction. Under Section 731 of the Code, a Santa Fe Common Unit holder will
recognize gain if, and only to the extent that, any Fractional Unit Payment made
to such holder exceeds the sum of such holder's tax basis in the newly acquired
KMEP Common Units (determined as described below) plus such holder's tax basis
in KMEP Common Units held prior to the Transaction, if any. However, see
"--Disguised Sale Rules" regarding possible alternative tax treatment of the
Fractional Unit Payments.
    
 
   
    BASIS AND HOLDING PERIOD OF KMEP COMMON UNITS.  Under Section 732(b) of the
Code, the tax basis of the KMEP Common Units received by a Santa Fe Common Unit
holder will be equal to the adjusted tax basis of such holder's Santa Fe Common
Units, which basis will be added to the basis of any KMEP Common Units held by
such holder. See "Disposition of KMEP Common Units--Recognition of Gain or
Loss." This basis will be immediately reduced, but not below zero, by the amount
of the Fractional Unit Payment received, if any.
    
 
   
    Under Section 735(b) of the Code, the holding period of the KMEP Common
Units in the hands of the Santa Fe Common Unit holders will include Santa Fe's
holding period for the SF Operating
    
 
                                      127
<PAGE>
   
Partnership limited partner interests which commenced no later than January 1,
1989, except to the extent the value of the partnership interests are
attributable to Section 751 assets other than depreciation recapture (E.G.,
unrealized receivables, inventory items and capital improvements not held by the
SF Operating Partnership for more than 12 months). The holding period of the
KMEP Common Units received by a Santa Fe Common Unit holder attributable to such
Section 751 assets of the SF Operating Partnership will begin on the day
following the date of the Transaction. The SF General Partner believes that an
insignificant portion of the value of the KMEP Common Units will be attributable
to such items.
    
 
   
    In addition, if there has been a constructive termination of Santa Fe
pursuant to Section 708(b)(1)(B) of the Code, the holding period of the SF
Operating Partnership limited partner interests, and consequently the holding
period of the KMEP Common Units in the hands of the Santa Fe Common Unit
holders, will begin on the day following such constructive termination to the
extent the value of the partnership interest in the SF Operating Partnership on
the date of such constructive termination was attributable to assets that did
not constitute either capital assets or Section 1231 assets (generally
depreciable assets and real property used in a business with a holding period of
more than 12 months) at such time. The SF General Partner believes that
approximately 12% of the value of the assets of the SF Operating Partnership are
attributable to such items. Under Section 708(b)(1)(B) of the Code, there would
have been a constructive termination when 50% or more of the total interests in
Santa Fe's capital and profits were transferred within any consecutive 12 month
period. The SF General Partner believes that there has not been a tax
termination of Santa Fe since its initial public offering in 1988--a belief that
is strengthened by the fact that it holds nearly approximately 42.6% of the
outstanding Santa Fe Common Units. Because Santa Fe Common Units could be held
in street names, it is possible, although highly unlikely, that 50% or more of
the Santa Fe Common Units could have been sold or exchanged within a consecutive
12 month period without the knowledge of the SF General Partner.
    
 
    As a result of the Transaction, the taxable year of Santa Fe will close on
the Closing Date and each Santa Fe Common Unit holder will be allocated a
ratable share of the income of Santa Fe for the short taxable year at this time.
Because both Santa Fe and KMEP are on a calendar tax year, Santa Fe Common Unit
holders who are on a calendar tax year will not have a "bunching" of income.
However, Santa Fe Common Unit holders with a fiscal tax year may realize a
bunching of income (I.E., more than 12 months of partnership income realized in
a partner's single tax year) as a result of the liquidation of Santa Fe.
 
   
    KMEP may be required to withhold and pay to the IRS a portion of the
Fractional Unit Payment that would otherwise be paid to a non-U.S. citizen (or
resident) (as determined for federal income tax purposes), or a foreign entity,
who is a Santa Fe Common Unit holder. In the event of over withholding, such
Santa Fe Common Unit holder would be required to file a United States tax return
or other application in order to obtain a refund of the overwithheld amount.
    
 
   
TAX CONSEQUENCES OF THE TRANSACTION TO KMEP AND KMEP COMMON UNIT HOLDERS
    
 
   
    GENERAL.  The federal income tax consequences described herein are dependent
upon KMEP being classified as a partnership for federal income tax purposes. See
"--General Features of Partnership Taxation--Partnership Status." Section 721(a)
of the Code provides that, as a general rule, no gain or loss is recognized by a
partnership or by any of its partners upon a contribution of property to a
partnership in exchange for an interest in the partnership. Pursuant to the
Purchase Agreement, Santa Fe will contribute its SF Operating Partnership LP
Interest to KMEP in exchange for KMEP Common Units. See "--Tax Consequences of
the Exchange and Distribution--Partnership Contributions and Distributions."
    
 
    INVESTMENT COMPANY RULES.  The 1997 Act significantly expanded the
definition of an investment company for purposes of determining whether gain or
loss is recognized upon a transfer of property to such an entity. These
provisions are also applicable to certain transfers of property to partnerships.
If a partnership would fall within the definition of an investment company and a
transfer of property is made to
 
                                      128
<PAGE>
   
it, the transferring partnership may recognize gain, but not loss, on such
transfer. See "--Tax Consequences of the Exchange and Distributions--Investment
Company Rules." If the Transaction were recharacterized as a merger, the holders
of the pre-Transaction KMEP Common Units would be deemed to have contributed the
KMEP assets to Santa Fe. Based upon representations of the SF General Partner
that no significant portion of its assets is comprised of stock or securities
(as defined above) or interests in RICs or REITs, Santa Fe would not be
considered an investment company. See "Tax Consequences of the Exchange and
Distribution--Investment Company Rules."
    
 
   
    RELIEF FROM LIABILITIES/DEEMED CASH DISTRIBUTION.  The pre-Transaction KMEP
Common Unit holders' partnership interests will reflect a different percentage
of ownership in KMEP after the Transaction than they had before the Transaction,
with such percentage of ownership determined by reference to the total number of
KMEP Common Units outstanding after the Transaction. A KMEP Common Unit holder's
basis in any partnership interest in KMEP includes such holder's share of
partnership liabilities under Section 752 of the Code. Under these rules, if a
KMEP Common Unit holder's share of liabilities is reduced, the amount of such
reduction is treated as a distribution. This amount is treated as a return of
basis and, if the amount exceeds the holder's adjusted tax basis, as gain. A
KMEP Common Unit holder, as a limited partner, will not have any share of KMEP
recourse liabilities before or after the Transaction. The KM General Partner has
also represented that KMEP and the KMEP Partnerships have either no, or an
insignificant amount of, nonrecourse liabilities that could be allocated to a
limited partner under Section 752. Accordingly, there will be no reduction in a
KMEP Common Unit holder's share of non-recourse liabilities and it is not
anticipated that any pre-Transaction KMEP Common Unit holder would recognize
gain as a result of the Transaction.
    
 
   
    REDEMPTION OF SPECIAL LP INTEREST.  As part of the Transaction, the SF
Operating Partnership will redeem approximately one-half of the Special LP
Interest for $5.8 million in cash. This redemption will be treated as a current
distribution and will reduce the cash flow otherwise available to holders of
KMEP Common Units without any corresponding reduction in the taxable income
allocated to such holders of KMEP Common Units or any corresponding Section
734(b) basis adjustment to KMEP assets for the other KMEP Common Unit holders.
    
 
   
    PURCHASE OF SANTA FE GENERAL PARTNER INTEREST.  An affiliate of KMEP, OLP-D,
will purchase the general partner interest in Santa Fe from the SF General
Partner for $84.4 million in cash. Pursuant to the Santa Fe and SF Operating
Partnership Agreements, a purchaser of a partnership interest receives the
benefit of a Section 743(b) basis adjustment in its allocable share of the
underlying assets of the SF Operating Partnership pursuant to a Section 754
election previously made by both partnerships. Accordingly, KMEP (and its Common
Unit holders) will indirectly, through its ownership in OLP-D, also receive the
benefit of the Section 743(b) basis adjustment to the extent that the amount
paid for such interest exceeds its allocable share of the SF Operating
Partnership's aggregate tax basis for its assets. For a general discussion of
the Section 743(b) basis adjustment, see "Tax Treatment of Operations--Section
754 Election."
    
 
TAX CONSEQUENCES OF THE TRANSACTION TO BOTH KMEP AND SANTA FE COMMON UNIT
  HOLDERS
 
   
    CAPITAL ACCOUNTS, VALUATION OF ASSETS AND CURATIVE ALLOCATIONS UNDER SECTION
704(c).  Pursuant to the KMEP Partnership Agreement and as a result of the
Transaction, the Capital Accounts of all holders of KMEP Common Units (both
pre-Transaction holders of KMEP Common Units and former holders of Santa Fe
Common Units) will be booked-up (increased) (the "Book-Up") to reflect the value
of assets deemed contributed by them to the post-Transaction KMEP. However,
generally, the tax basis of the assets contributed or deemed contributed will
not be correspondingly increased, but will carryover from the tax basis of such
assets in the hands of Santa Fe and KMEP and their respective operating
partnerships. Crediting a partner's capital account with the fair market value
of such property creates a disparity between the partner's book capital account
and a pure "tax" capital account (a "Book-Tax Disparity"),
    
 
                                      129
<PAGE>
   
because the tax capital account would reflect only the tax basis rather than the
value of KMEP's property. Section 704(c) provides that this "Book-Tax Disparity"
may be eliminated by making tax allocations based on book depreciation or book
amortization of such revalued property to partners other than those who
contributed (or are deemed to have contributed) the property to KMEP. However,
the Treasury Regulations provide that a partnership cannot allocate more
depreciation or amortization (or loss) than the total amount recognized for tax
purposes by such partnership in a particular tax period (the "Ceiling Rule").
Additional allocations will be made pursuant to the KMEP Partnership Agreement
to eliminate any remaining Book-Tax Disparity with respect to a partnership
asset ("Curative Allocations"). See "--Allocation of KMEP Income, Gain, Loss and
Deduction." The Section 704(c) allocation and the Curative Allocations
effectively give the pre-Transaction KMEP Common Unit holders or the former
Santa Fe Common Unit holders the benefit of a share of depreciation or
amortization attributable to the value of the property deemed contributed by the
other group to compensate for the fact that such depreciation or amortization
would otherwise be limited by the tax basis of the property and the application
of the Ceiling Rule. No Section 704 allocation or Curative Allocations would be
available with respect to goodwill which is not amortizable because of the
Anti-Churning rules and the Step-in the Shoes rules. See "--Section 197
Intangibles."
    
 
   
    The KM General Partner has obtained independent appraisals of the assets of
the SF Operating Partnership, KMEP and the KMEP Operating Partnerships, which
indicate that, based upon the current publicly-traded price for KMEP Units,
these entities have a value which equals or exceeds such total market
capitalization and debt of KMEP following the Transaction. These appraisals
indicate that all of the SF Operating Partnership value and the KMEP value is
attributable to tangible assets.
    
 
   
    If the IRS were to challenge either or both of the valuations obtained by
the KM General Partner and successfully contend that a portion of such value is
attributable to intangible assets (or otherwise adjust allocations to and among
various classes of depreciable assets) of the SF Operating Partnership or KMEP
and the KMEP Operating Partnerships, the Section 704(c) allocations and the
Curative Allocations attributable to such assets which were made in favor of the
group of non-contributing holders of KMEP Common Units could be reduced or, as
to some assets, eliminated. This would, to the extent the Section 704(c)
allocations and the Curative Allocations were reduced on a net basis to either
the former Santa Fe holders of KMEP Common Units or the pre-Transaction holders
of KMEP Common Units, adversely affect (increase) the amount of taxable income
allocable to the noncontributing group otherwise receiving the benefit of such
allocations. Such a reduction of the Section 704(c) allocations and the Curative
Allocations could occur either because value is reallocated to assets with
longer depreciable or amortizable lives or because of the application of certain
limitations on the amortization of intangibles held prior to August 10, 1993 and
self-created intangibles. See "--Section 197 Intangibles". Such a challenge, if
made and successful, could have a material adverse effect on the after-tax
economic benefit to a KMEP Common Unit holder and depending on the amount
ultimately allocated to non-amortizable intangibles or longer lived assets, such
adverse effect could be material. It should be noted that there is considerable
uncertainty as to the interplay of, and scope of such limitations with respect
to, the provisions of the Code dealing with partnerships, the allocation
provisions of Section 704(c), including Curative Allocations, and, in
particular, the revaluation of Section 197 Intangibles as subsequently
discussed. Morrison & Hecker does not render valuation opinions and,
accordingly, is unable to opine whether such valuations and the resulting
anticipated Section 704(c) allocations and Curative Allocations would be
sustained if challenged by the IRS. A prospective KMEP Common Unit holder is
encouraged to consult a tax advisor with respect to the potential impact of the
Section 704(c) allocations and the Curative Allocations on such Common Unit
holder's interest in KMEP. See "--Distinct Tax Attributes of KMEP Common Units."
    
 
                                      130
<PAGE>
   
    SECTION 197 INTANGIBLES.  Section 197 provides that a taxpayer may amortize
the adjusted basis of an "Amortizable Section 197 Intangible" ratably over a
period of 15 years beginning with the month in which the intangible asset was
acquired. An "Amortizable Section 197 Intangibles" is defined as a "Section 197
Intangible" acquired after August 10, 1993, which is held in connection with the
conduct of a trade or business or an activity described in Section 212. A
"Section 197 Intangible" is defined broadly to include goodwill, going concern
value, workforce in place, business books and records, operating systems,
patents, copyrights, formulas, processes, designs, know how or other similar
items, any customer based intangible, any supplier based intangible, any
license, permit or other right, any covenant not to compete and any franchise,
trademark or tradename.
    
 
    Proposed Treasury Regulations under Section 197 set forth rules intended to
prevent a taxpayer from converting what would otherwise be a non-amortizable
intangible into an Amortizable Section 197 Intangible. These rules are commonly
referred to as the "Anti-Churning" rules and the nonrecognition transaction or
"Step-in-the-Shoes" rules. Non-amortizable intangibles include intangibles
created by the taxpayer (subject to certain exceptions), pre-August 10, 1993
intangibles and intangibles subject to the aforementioned rules.
 
   
    As a result of the Transaction, pre-Transaction holders of KMEP Common Units
are effectively acquiring an interest in intangibles, if any, held by the SF
Operating Partnership and Santa Fe Common Unit holders are acquiring an interest
in intangibles, if any, held by KMEP and the KMEP Operating Partnerships in a
Section 721 nonrecognition transaction. Proposed Treasury Regulation Section
1.197-2(g)(2)(vi) provides that a Curative Allocation, attributable to any
non-amortizable intangible contributed to KMEP would not be available to the
KMEP Common Unit holders who would otherwise receive its benefit. As previously
indicated, the KM General Partner anticipates that there will be an
insignificant allocation of value, if any, to non-amortizable intangibles as a
result of the Transaction. See "--Capital Accounts, Valuation of Assets and
Curative Allocations under Section 704(c)." If the IRS were to challenge the
independent appraisals obtained by the KM General Partner and successfully
assert that a greater portion of the Book-Tax Disparity inherent in the SF
Operating Partnership LP Interest is attributable to non-amortizable
intangibles, a pre-Transaction KMEP Common Unit holder would be denied the
benefit of any Curative Allocation to that extent. Similarly, if the IRS were to
challenge the independent appraisals and successfully assert that a portion of
the Book-Tax Disparity inherent in the KMEP or the KMEP Operating Partnerships
is attributable to non-amortizable intangibles, Santa Fe Common Unit holders
would be denied the benefit of any Curative Allocations to that extent. As
previously noted, Morrison & Hecker does not render valuation opinions and,
accordingly, is unable to opine as to whether the allocation of value in such
independent appraisals would be sustained if challenged by the IRS. Such a
challenge, if made and successful, could have an adverse effect on the after-tax
economic benefit to a KMEP Common Unit holder and depending on the amount
ultimately allocated to non-amortizable intangibles or longer lived assets, such
adverse effect could be material.
    
 
   
    It is not clear how the previously mentioned rules are applied, if at all,
to revalued or "Booked-Up" intangibles that are not contributed (I.E.,
non-amortizable intangibles, if any, held by KMEP prior to the Transaction) when
there is no taxable transaction resulting in a step up in tax basis. It may be
contended that neither the Anti-Churning rules nor the Step-in-the-Shoes rules
apply to deny Curative Allocations with respect to the Book-Tax Disparity of
revalued (but not contributed) intangibles. However, it is likely that the IRS
would take the position that the intent of the Section 197 Proposed Treasury
Regulations is to deny the benefit of any Curative Allocation attributable to an
intangible the tax basis of which is not otherwise amortizable under Section
197, regardless of whether such excess book basis results from contribution or
revaluation upon a book-up. This issue would arise only if the appraisals
obtained by the KM General Partner were challenged successfully with a resulting
allocation to intangibles not otherwise amortizable under Section 197 or
pre-Section 197 case law (if Section 197 is otherwise inapplicable). Any such
challenge, if successful, could have an adverse impact on the ratio of the
taxable income to cash distributions of any holders of KMEP Common Units. See
"--Tax Consequences of KMEP Common Unit Ownership--Ratio of Taxable Income to
Distributions."
    
 
                                      131
<PAGE>
   
    Proposed Treasury Regulation Section 1.197-2(h)(5) provides that in
determining whether the Anti-Churning rules apply to any increase in partnership
basis resulting from a Section 754 election, the determinations of relatedness
are made at the partner level and each partner is treated as having owned and
used the partner's proportionate share of the partnership's property. Any
Section 743 step-up in basis allocated to intangible assets is treated as a new
intangible with a 15 year amortization period commencing on the date of the
acquisition of an interest in KMEP. Accordingly, the Anti-Churning rules would
not apply to the Section 743 basis step-up attributable to intangibles when a
purchaser acquires a KMEP Common Unit by purchase after the Transaction,
assuming such KMEP Common Unit holder is not related to the purchaser within the
meaning of the related party rules of Section 707 or Section 267.
    
 
   
    DISTINCT TAX ATTRIBUTES OF KMEP COMMON UNITS.  Until such time as a KMEP
Common Unit is sold in the market after the Transaction, the revaluation of
assets and book-up of the Capital Accounts of the former Santa Fe Common Unit
holders and pre-Transaction KMEP Common Unit holders will create distinct tax
attributes in these respective groups of holders after the Transaction. This is
due to Section 704(c)'s requirement that any gain inherent in an asset as of the
date of its contribution to a partnership must be allocated to the contributing
partner and any built-in gain inherent in the assets which are revalued must be
allocated to those partners holding interests immediately prior to the Book-Up
event. For example, if an asset previously held by Santa Fe were sold after the
Transaction at a price equal to its fair market value as of the date of the
Transaction and such amount was greater than the tax basis of such asset, under
Section 704(c) the taxable gain (the "Section 704(c) Gain") reduced by any
intervening Curative Allocations must be specially allocated to the former Santa
Fe Common Unit holders or their transferees. Pre-Transaction KMEP Common Unit
holders, or their transferees, would receive a similar allocation of Section
704(c) Gain inherent in KMEP assets as of the date of the Transaction that is
recognized in a taxable transaction or a distribution of such property. Any such
special allocation of Section 704(c) Gain would not entitle any holder to a
greater cash distribution than any other KMEP Common Unit holder and would not
increase such KMEP Common Unit holder's capital account. As a result, in any
particular year, the ratio of taxable income to cash distributions could vary
between pre-Transaction KMEP Common Unit holders and former Santa Fe Unit
holders holding KMEP Common Units depending on what dispositions, if any, of
assets occur during a year. See "--Tax Consequences of KMEP Common Unit
Ownership--Ratio of Taxable Income to Distributions."
    
 
   
    The portion of KMEP assets allocable to any KMEP Common Unit sold in a
particular month will receive a Section 743(b) basis adjustment with respect to
the Purchaser of such units as a result of KMEP's Section 754 Election. The
amount of the Section 743(b) adjustment is equal to the difference between the
purchaser's initial basis in his KMEP Common Units and his proportionate share
of the adjusted basis of KMEP's property. This adjustment together with certain
conventions adopted by KMEP should ensure the fungibility of KMEP Common Units
purchased in any month. See "--Tax Treatment of Operations-- Section 754
Election" and "--Uniformity of KMEP Common Units." However, KMEP Common Units
purchased during different months at different prices will have distinct tax
attributes, because of the Section 704(c) effects previously discussed and the
unique amount of Section 743(b) basis adjustment attributable to the amount by
which the purchase price of such KMEP Common Unit exceeds its proportionate
share of the inside common tax basis of KMEP assets. See "Tax Treatment of
Operations-- Section 754 Election."
    
 
   
    FUNGIBILITY ISSUES ARISING FROM INTANGIBLES.  If an allocation of value were
made to intangible assets of pre-Transaction KMEP, Santa Fe or their operating
partnerships, issues as to the fungibility of KMEP Common Units following the
Transaction could arise. However, under the KMEP Partnership Agreement, the KM
General Partner is authorized to adopt such conventions as it deems appropriate,
to amend the KMEP Partnership Agreement to reflect Treasury Regulations or act
otherwise to preserve or achieve uniformity of the KMEP Common Units. The KM
General Partner intends to depreciate the portion of a Section 743(b) adjustment
attributable to unrealized appreciation in the value of property contributed or
deemed contributed (to the extent of any unamortized Book-Tax Disparity) using a
rate of depreciation
    
 
                                      132
<PAGE>
   
derived from the depreciation method and useful life applied to the Common Basis
(as defined below) of such property. Such a convention is not technically in
compliance with applicable sections of the Code and, accordingly, Morrison &
Hecker is unable to opine as to whether such a convention would be respected if
challenged by the IRS. The impact of such a challenge, if successful, would
depend upon the amount allocated to intangibles. Any such allocation of amounts
to intangibles of either Santa Fe or the former KMEP would result in a reduction
of the net Curative Allocation made to the other group of Common Unit holders
(either former Santa Fe Common Unit holders or pre-Transaction KMEP Common Unit
holders) and a corresponding increase their allocable shares of KMEP taxable
income.
    
 
   
    CONSTRUCTIVE TERMINATION OF PARTNERSHIPS.  As a result of the distribution
of KMEP Common Units by Santa Fe and other sales of KMEP Common Units it is
likely that there will be a constructive tax termination of KMEP and its
Operating Partnerships under Section 708(b)(1)(B), I.E., sales or exchanges of
50% or more of the interests in KMEP's capital and profits. KMEP would be deemed
constructively terminated on such date resulting in a close of its taxable year
and a "new" KMEP being formed. The SF Operating Partnership will also be
constructively terminated as a result of KMEP's acquisition of the SF Operating
Partnership LP Interest. A constructive termination will result in new
depreciable and amortizable lives for assets held by KMEP (including those held
by the SF Operating Partnership), which will result in a net deferral of such
deductions with respect to both common inside tax basis of KMEP and SF Operating
Partnership assets and any basis adjustment attributable to the purchase price
paid by a KMEP or Santa Fe Common Unit holder. A constructive termination would
also result in a deferral of net Curative Allocations, if any, under Section
704(c). The amount of depreciation deductions and net Curative Allocations
available to a Common Unit holder may be a major contributing factor in
determining the differences in the ratio of taxable income to cash distributions
which will be realized by any KMEP Common Unit holder following the Transaction.
The constructive terminations of the SF Operating Partnership and KMEP resulting
from the Transaction will result in new (a restart of) depreciable lives for the
assets held and a resulting deferral of both depreciation attributable to common
inside tax basis of such assets and the net Curative Allocations attributable to
such assets. In addition, most of the SF Operating Partnership and KMEP assets
are in asset classes which utilize a mid-year convention for the year of the
acquisition and disposition of such assets. Accordingly, in 1998, the KM General
Partner estimates that the effect of such constructive terminations and
depreciation conventions will be a reduction of approximately 50% in the
depreciation deductions and net Curative Allocations available to former Santa
Fe Common Unit holders and pre-Transaction KMEP Common Unit holders. The KM
General Partner estimates there will be no material adverse effect on
depreciation deductions and Curative Allocations for the years 1999 and 2000 as
a result of such constructive termination. See "--Disposition of KMEP Common
Units-- Constructive Termination." Because both KMEP and Santa Fe are on a
calendar tax year, any holder on a calendar tax year will not have a "bunching"
of income. In addition, a pre-Transaction KMEP Common Unit holder or a former
Santa Fe Common Unit holder with a fiscal tax year may realize a bunching of
income (I.E., more than 12 months of partnership income realized in a holder's
single tax year) as a result of the constructive termination.
    
 
GENERAL FEATURES OF PARTNERSHIP TAXATION
 
    PARTNERSHIP STATUS.  The applicability of the federal income tax
consequences described herein depends on the treatment of KMEP and the KMEP
Partnerships as partnerships for federal income tax purposes and not as
associations taxable as corporations. For federal income tax purposes, a
partnership is not a taxable entity, but rather a conduit through which all
items of partnership income, gain, loss, deduction and credit are passed through
to its partners. Thus, income and deductions resulting from partnership
operations are allocated to the partners and are taken into account by the
partners on their individual federal income tax returns. In addition, a
distribution of money from a partnership to a partner generally is not taxable
to the partner, unless the amount of the distribution exceeds the partner's tax
basis in the partner's interest in the partnership. If KMEP or any of the KMEP
Partnerships formed as a partnership were classified for federal income tax
purposes as an association taxable as a corporation, the
 
                                      133
<PAGE>
entity would be a separate taxable entity. In such a case, the entity, rather
than its members, would be taxed on the income and gains and would be entitled
to claim the losses and deduction resulting from its operations. A distribution
from the entity to a member would be taxable to the member in the same manner as
a distribution from a corporation to a shareholder (I.E., as ordinary income to
the extent of the current and accumulated earnings and profits of the entity,
then as a nontaxable reduction of basis to the extent of the member's tax basis
in the member's interest in the entity and finally as gain from the sale or
exchange of the member's interest in the entity). Any such characterization of
either KMEP or one of the KMEP Partnerships as an association taxable as a
corporation would likely result in a material reduction of the anticipated cash
flow and after-tax return to the KMEP Common Unit holders.
 
   
    Pursuant to Final Treasury Regulations 301.7701-1, 301.7701-2 and
301.7701-3, effective January 1, 1997 (the "Check-the-Box Regulations"), an
entity in existence on January 1, 1997, will generally retain its current
classification for federal income tax purposes. As of January 1, 1997, KMEP was
classified and taxed as a partnership. Pursuant to the Check-the-Box Regulations
this prior classification will be respected for all periods prior to January 1,
1997, if (1) the entity had a reasonable basis for the claimed classification;
(2) the entity recognized federal tax consequences of any change in
classification within five years prior to January 1, 1997; and (3) the entity
was not notified prior to May 8, 1996, that the entity classification was under
examination. Prior to the finalization of the Check-the-Box Regulations, the
classification of an entity as a partnership was determined under a four factor
test developed by a number of legal authorities. Based on this four factor test,
KMEP had a reasonable basis for its classification as a partnership. Moreover,
KMEP has not changed its classification and it has not received any notification
that its classification was under examination.
    
 
   
    The Check-the-Box Regulations provide that organizations are classified
thereunder "unless a provision under the Internal Revenue Code . . . provides
for special treatment of that organization." Although the natural resources or
passive type income exception to corporate classification for publicly traded
partnerships is a provision providing special treatment, it is uncertain whether
the four factor test would still apply to KMEP. This provision most likely is
intended solely to recognize that statutorily imposed requirements prerequisite
to partnership classification remain in effect. Based on this interpretation,
Morrison & Hecker is of the view that such prior law classification authorities
are relevant only with respect to pre-January 1, 1997 tax periods.
    
 
   
    Section 7704 provides that publicly traded partnerships will, as a general
rule, be taxed as corporations. However, an exception exists with respect to
publicly traded partnerships 90% or more of the gross income of which for every
taxable year consists of "qualifying income" (the "Natural Resource Exception").
"Qualifying income" includes income and gains derived from the exploration,
development, mining or production, processing, refining, transportation
(including pipelines) or marketing of any mineral or natural resource including
oil, natural gas or products thereof. Other types of "qualifying income" include
interest, dividends, gains from the sale of real property and gains from the
sale or other disposition of capital assets held for the production of income
that otherwise constitute "qualifying income." The KM General Partner has
represented that in excess of 90% of KMEP's gross income will be derived from
fees and charges for transporting (through the Liquids Pipelines) NGLs, CO(2)
and other hydrocarbons, dividends from the corporation that owns the Mont
Belvieu Fractionator and interest. Based upon that representation, Morrison &
Hecker is of the opinion that KMEP's gross income derived from these sources
will constitute "qualifying income."
    
 
   
    If (a) a publicly traded partnership fails to meet such 90% gross income
test for any taxable year, (b) such failure is inadvertent, as determined by the
IRS, and (c) the partnership takes steps within a reasonable time to once again
meet the gross income test and agrees to make such adjustments and pay such
amounts (including, possibly, the amount of tax liability that would be imposed
on the partnership if it were treated as a corporation during the period of
inadvertent failure) as are required by the IRS, such failure will not cause the
partnership to be taxed as a corporation. The KM General Partner, as general
partner of KMEP, will use its best efforts to assure that KMEP will continue to
meet the gross income test
    
 
                                      134
<PAGE>
for each taxable year and KMEP anticipates that it will meet the test. If KMEP
fails to meet the gross income test with respect to any taxable year, the KM
General Partner, as general partner of KMEP, will use its best efforts to assure
that KMEP will qualify under the inadvertent failure exception discussed above.
 
   
    If KMEP fails to meet the Natural Resource Exception (other than a failure
determined by the IRS to be inadvertent that is cured within a reasonable time
after discovery), KMEP will be treated as if it had transferred all of its
assets (subject to liabilities) to a newly-formed corporation (on the first day
of the year in which it fails to meet the Natural Resource Exception) in return
for stock in such corporation, and then distributed such stock to the partners
in liquidation of their interests in KMEP. This contribution and liquidation
should be tax-free to the holders of KMEP Common Units and KMEP, so long as
KMEP, at such time, does not have liabilities in excess of the basis of its
assets. Thereafter, KMEP would be treated as a corporation.
    
 
   
    If KMEP were treated as an association or otherwise taxable as a corporation
in any taxable year, as a result of a failure to meet the Natural Resource
Exception or otherwise, its items of income, gain, loss, deduction and credit
would be reflected only on its tax return rather than being passed through to
the holders of KMEP Common Units, and its net income would be taxed at the
entity level at corporate rates. In addition, any distribution made to a holder
of KMEP Common Units would be treated as either taxable dividend income (to the
extent of KMEP's current or accumulated earnings and profits), or, in the
absence of earnings and profits as a nontaxable return of capital (to the extent
of the holder's basis in the KMEP Common Units) or taxable capital gain (after
the holder's basis in the KMEP Common Units is reduced to zero.) Accordingly,
treatment of either KMEP or any of the KMEP Partnerships as an association
taxable as a corporation would result in a material reduction in a holder's cash
flow and after-tax economic return on an investment in KMEP.
    
 
   
    There can be no assurance that the law will not be changed so as to cause
KMEP to be treated as an association taxable as a corporation for federal income
tax purposes or otherwise to be subject to entity-level taxation. The KMEP
Partnership Agreement provides that, if a law is enacted that subjects KMEP to
taxation as a corporation or otherwise subjects KMEP to entity-level taxation
for federal income tax purposes, certain provisions of the KMEP Partnership
Agreement relating to the KM General Partner's incentive distributions will be
subject to change. See "Description of KMEP Partnership Agreement-- Cash
Distribution Policy--Adjustment of Target Distribution Levels."
    
 
   
    Under current law, KMEP and the KMEP Partnerships will be classified and
taxed as partnerships for federal income tax purposes and will not be classified
as associations taxable as corporations. This conclusion is based upon (i) an
opinion of Mayer, Brown & Platt as to certain matters relating to Santa Fe and
certain factual representations and covenants of the SF General Partner relevant
to such opinion; and (ii) certain factual representations and covenants made by
the KM General Partner including:
    
 
        (a)  KMEP and the KMEP Partnerships will be operated strictly in
    accordance with (i) all applicable partnership statutes, (ii) the KMEP
    Partnership Agreement and (iii) this Joint Proxy Statement/Prospectus;
 
        (b)  Except as otherwise required by Section 704 and the Regulations
    promulgated thereunder, the KM General Partner will have an interest in each
    material item of income, gain, loss, deduction or credit of KMEP and each of
    the KMEP Partnerships equal to at least 1% at all times during the existence
    of KMEP and the KMEP Partnerships;
 
        (c)  The KM General Partner will maintain a minimum capital account
    balance in KMEP and in the KMEP Partnerships equal to 1% of the total
    positive capital account balances of KMEP and the KMEP Partnerships;
 
        (d)  The KM General Partner will at all times act independently of the
    KMEP Common Unit holders;
 
                                      135
<PAGE>
   
        (e)  For each taxable year, less than 10% of the aggregate gross income
    of KMEP and the KMEP Partnerships will be derived from sources other than
    (i) the exploration, development, production, processing, refining,
    transportation or marketing of any mineral or natural resource, including
    oil, gas or products thereof and naturally occurring carbon dioxide or (ii)
    other items of "qualifying income" within the definition of Section 7704(d);
    
 
        (f)  The KM General Partner has maintained throughout the term of KMEP
    and the KMEP Partnerships prior to January 1, 1997, substantial assets
    (based upon the fair market value of its assets and excluding its interest
    in, and any account or notes receivable from or payable to, any limited
    partnership in which the KM General Partner has any interest) that could be
    reached by the creditors of KMEP and the KMEP Partnerships; and
 
        (g)  The KM General Partner has not elected association classification
    under the Check-the-Box Regulations and will not elect such classification.
 
   
    No ruling from the IRS has been requested or received with respect to the
classification of KMEP and the KMEP Partnerships for federal income tax purposes
and the opinion of Morrison & Hecker is not binding on the IRS. The IRS imposed
certain procedural requirements for years prior to 1997 to be met before it
would issue a ruling to the effect that a limited partnership with a sole
corporate general partner would be classified as a partnership for federal
income tax purposes. These procedural requirements were not rules of substantive
law to be applied on audit, but served more as a "safe-harbor" for purposes of
obtaining a ruling. The KM General Partner believes that KMEP and the KMEP
Partnerships did not satisfy all such procedural requirements. The conclusion
described above as to the partnership status of KMEP for years before January 1,
1997 does not depend upon the ability of KMEP to meet the criteria set forth in
such procedural requirements.
    
 
   
    The following discussion assumes that KMEP and the KMEP Partnerships are,
and will continue to be, treated as partnerships for federal income tax
purposes. If either assumption proves incorrect, most, if not all, of the tax
consequences described herein would not be applicable to KMEP Common Unit
holders. In particular, if KMEP is not a partnership, a KMEP Common Unit holder
may be treated for federal income tax purposes (i) as recognizing ordinary
income, as the result of any payments to him in respect of partnership
distributions and (ii) as not being entitled to allocations of partnership
income, gain, loss and deduction.
    
 
   
    LIMITED PARTNER STATUS.  Holders of KMEP Common Units who have been admitted
as limited partners will be treated as partners of KMEP for federal income tax
purposes. Moreover, the IRS has ruled that assignees of partnership interests
who have not been admitted to a partnership as partners, but who have the
capacity to exercise substantial dominion and control over the assigned
partnership interests, will be treated as partners for federal income tax
purposes. On the basis of this ruling, except as otherwise described herein, (a)
assignees who have executed and delivered Transfer Applications, and are
awaiting admission as limited partners and (b) holders of KMEP Common Units
whose KMEP Common Units are held in street name or by another nominee and who
have the right to direct the nominee in the exercise of all substantive rights
attendant to the ownership of their KMEP Common Units will be treated as
partners of KMEP for federal income tax purposes. As this ruling does not
extend, on its facts, to assignees of KMEP Common Units who are entitled to
execute and deliver Transfer Applications and thereby become entitled to direct
the exercise of attendant rights, but who fail to execute and deliver Transfer
Applications, Morrison & Hecker cannot opine as to the status of these persons
as partners of KMEP. Income, gain, deductions, losses or credits would not
appear to be reportable by such a holder of KMEP Common Units, and any cash
distributions received by such holders of KMEP Common Units would therefore be
fully taxable as ordinary income. These holders should consult their own tax
advisors with respect to their status as partners in KMEP for federal income tax
purposes. A purchaser or other transferee of KMEP Common Units who does not
execute and deliver a Transfer Application may not receive certain federal
income tax information or reports furnished to record holders of KMEP Common
Units, unless the KMEP Common
    
 
                                      136
<PAGE>
Units are held in a nominee or street name account and the nominee or broker has
executed and delivered a Transfer Application with respect to such KMEP Common
Units.
 
   
    A beneficial owner of KMEP Common Units whose KMEP Common Units have been
transferred to a short seller to complete a short sale would appear to lose the
status of a partner with respect to such KMEP Common Units for federal income
tax purposes. See "--Disposition of KMEP Common Units-- Treatment of Short
Sales."
    
 
TAX CONSEQUENCES OF KMEP COMMON UNIT OWNERSHIP
 
   
    BASIS OF KMEP COMMON UNITS.  A KMEP Common Unit holder's initial tax basis
for a KMEP Common Unit will be the amount paid for the KMEP Common Unit or, in
the case of a former holder of a Santa Fe Common Unit, an amount determined
under Section 732. See "--Tax Consequences of the Exchange and
Distribution--Basis and Holding Period of KMEP Common Units." The initial tax
basis for a KMEP Common Unit will be increased by the KMEP Common Unit holder's
share of KMEP income and by the increase in the KMEP Common Unit holder's share
of KMEP nonrecourse liabilities, if any. The basis for a KMEP Common Unit will
be decreased (but not below zero) by distributions from KMEP, including any
decrease in the holders of KMEP Common Units' share of KMEP nonrecourse
liabilities, by the KMEP Common Unit holder's share of KMEP losses and by the
KMEP Common Unit holder's share of expenditures of KMEP that are not deductible
in computing its taxable income and are not required to be capitalized. A KMEP
Common Unit holder's share of nonrecourse liabilities, if any, will be generally
based on such holder's share of KMEP's profits.
    
 
   
    FLOW-THROUGH OF TAXABLE INCOME.  No federal income tax will be paid by KMEP.
Instead, each holder of KMEP Common Units will be required to report on such
holder's income tax return such holder's allocable share of the income, gains,
losses and deductions of KMEP without regard to whether corresponding cash
distributions are received by such holders of KMEP Common Units. Consequently, a
holder of KMEP Common Units may be allocated income from KMEP even though the
holder has not received a cash distribution in respect of such income.
    
 
   
    TREATMENT OF KMEP DISTRIBUTIONS.  Distributions by KMEP to a holder of KMEP
Common Units generally will not be taxable to the holders of KMEP Common Units
for federal income tax purposes to the extent of such holder's basis in KMEP
Common Units immediately before the distribution. Cash distributions in excess
of such KMEP Common Unit holder's basis generally will be considered to be gain
from the sale or exchange of the KMEP Common Units, taxable in accordance with
the rules described under "--Disposition of KMEP Common Units."
    
 
   
    A decrease in a KMEP Common Unit holder's percentage interest in KMEP,
because of the issuance by KMEP of additional KMEP Common Units, or otherwise,
will decrease current a KMEP Common Unit holder's share of nonrecourse
liabilities of KMEP, if any, and thus will result in a corresponding deemed
distribution of cash. KMEP does not currently have, and the KM General partner
does not anticipate that it will have, any material amounts of nonrecourse
liabilities.
    
 
   
    A non-pro rata distribution of money or property may result in ordinary
income to a holder of KMEP Common Units, regardless of such holder's tax basis
in KMEP Common Units, if the distribution reduces such holder's share of KMEP's
"Section 751 Assets." "Section 751" Assets are defined by the Code to include
assets giving rise to depreciation recapture or other "unrealized receivables"
or "substantially appreciated inventory". For this purpose, inventory is
substantially appreciated if its value exceeds 120% of its adjusted basis. In
addition to depreciation recapture, "unrealized receivables" include rights to
payment for goods (other than capital assets) or services to the extent not
previously includible in income under a partnership's method of accounting. To
the extent that such a reduction in a KMEP Common Unit holder's share of Section
751 Assets occurs, KMEP will be deemed to have distributed a proportionate share
of the Section 751 Assets to the KMEP Common Unit holders followed by a deemed
exchange of such assets with KMEP in return for the non-pro rata portion of the
actual distribution made to such
    
 
                                      137
<PAGE>
   
holder. This deemed exchange will generally result in the realization of
ordinary income under Section 751(b) by the KMEP Common Unit holder. Such income
will equal the excess of (1) the non-pro rata portion of such distribution over
(2) the KMEP Common Unit holder's tax basis in such holder's share of Section
751 Assets deemed relinquished in the exchange.
    
 
   
    Under the 1997 Act, the Secretary of the Treasury is granted regulatory
authority under Section 704(c)(1)(B) to treat a partnership's distribution of
property (to a partner other than the contributing partner) within seven years
of such property's contribution to the partnership as if the property had been
sold at the time of its contribution. Gain or loss would be recognized by the
contributing partner and the character of the gain or loss will be determined by
the character such gain or loss would have had if the property had been sold by
the partnership. The KM General Partner has represented that it has no current
intention of distributing any property deemed contributed in the Transaction to
any partner; accordingly, no such gain on in-kind distributions of property
should accrue to any holder of KMEP Common Units.
    
 
   
    FACTORS AFFECTING TAXABLE INCOME.  It is extremely difficult to project with
any precision the ratio of taxable income to cash distributions for any
particular KMEP Common Unit holder following the Transaction. The amount of
taxable income recognized by any particular KMEP Common Unit holder in any
particular year will depend upon a number of factors including, but not limited
to: (a) the amount of federal taxable income generally recognized by KMEP; (b)
the gains attributable to specific asset sales that may be wholly or partially
attributable to Section 704(c) Gain which will be specially allocated to either
the pre-Transaction KMEP Common Unit holders or the former Santa Fe Common Unit
holders depending on which asset(s) are sold; (c) the Section 743(b) basis
adjustment available to any particular KMEP Common Unit holder based upon its
purchase price for a KMEP Common Unit or a Santa Fe Common Unit and the amount
by which such price exceeded the proportionate share of inside tax basis of KMEP
assets attributable to such KMEP Common Unit when such KMEP Common Unit or Santa
Fe Common Unit was purchased; and (d) the impact of any adjustments to taxable
income reported by KMEP or conventions utilized by the KM General Partner in
allocating Curative Allocations between and among KMEP Common Unit holders. The
amounts of depreciation deductions and net Curative Allocations available to a
Common Unit holder may be a major contributing factor to the differences in the
amount of taxable income allocated to any KMEP Common Unit holder following the
Transaction. The constructive terminations of the SF Operating Partnership and
KMEP resulting from the Transaction and other sales of interests will result in
(i) a restart of depreciable lives for the assets held; (ii) a deferral of both
depreciation attributable to common inside tax basis of such assets and the net
Curative Allocations attributable to such assets; and (iii) a deferral of
depreciation attributable to basis adjustments resulting from the purchase price
paid by a KMEP Common Unit holder. In addition, most of the SF Operating
Partnership and KMEP assets are in asset classes which utilize a mid-year
convention for the year of the acquisition and disposition of such assets.
Accordingly, in 1998, the KM General Partner estimates that the effect of such
constructive terminations and depreciation conventions will be a reduction of
50% in the depreciation deductions and net Curative Allocations available to
former Santa Fe Common Unit holders and pre-Transaction KMEP Common Unit
holders. The KM General Partner estimates there will be no material adverse
effect on depreciation deductions and Curative Allocations for the years 1999
and 2000. This reduction in depreciation deductions and net Curative Allocations
will increase the federal taxable income, and therefore could increase the
federal income tax liability, of pre-Transaction holders of Santa Fe Common
Units and KMEP Common Units, when compared to such income absent the
Transaction. Further, the taxable income reported will be based on certain tax
reporting positions that the KM General Partner intends to adopt and with which
the IRS could disagree. See "Tax Treatment of Operations--Section 754 Election."
    
 
   
    LIMITATIONS ON DEDUCTIBILITY OF KMEP LOSSES.  To the extent losses are
incurred by KMEP, a KMEP Common Unit holder's deductions for such holder's share
of such losses will be limited to the tax basis of the KMEP Common Units held by
such holder or, in the case of an individual holder of KMEP Common Units or a
corporate holder of KMEP Common Units if more than 50% in the value of its stock
is owned
    
 
                                      138
<PAGE>
   
directly or indirectly by five or fewer individuals or certain tax-exempt
organizations, to the amount that the KMEP Common Unit holder is considered to
be "at risk" with respect to KMEP's activities, if that amount is less than the
holder's basis in the KMEP Common Units. A holder of KMEP Common Units must
recapture losses deducted in previous years to the extent that KMEP
distributions cause the KMEP Common Unit holders' at risk amount to be less than
zero at the end of any taxable year. Losses disallowed to a holder of KMEP
Common Units or recaptured as a result of theses limitations will carry forward
and will be allowable to the extent that the KMEP Common Unit holder's basis or
at risk amount (whichever is the limiting factor) is increased.
    
 
   
    In general, a holder of KMEP Common Units will be at risk to the extent of
the purchase price of the holder's KMEP Common Units but this may be less than
the KMEP Common Unit holder's basis for the KMEP Common Units in an amount equal
to the KMEP Common Unit holder's share of nonrecourse liabilities, if any, of
KMEP. A KMEP Common Unit holder's at risk amount will increase or decrease as
the basis of such KMEP Common Unit holder increases or decreases.
    
 
   
    The passive loss limitations generally provide that individuals, estates,
trusts and certain closely-held corporations and personal service corporations
can only deduct losses from passive activities (generally, activities in which
the taxpayer does not materially participate) that are not in excess of the
taxpayer's income from such passive activities or investments. The passive loss
limitations are to be applied separately with respect to each publicly traded
partnership. Consequently, the losses generated by KMEP, if any, will only be
available to offset future income generated by KMEP and will not be available to
offset income from other passive activities or investments (including other
publicly traded partnerships) or salary or active business income. Passive
losses that are not deductible, because they exceed the KMEP Common Unit
holder's allocable share of income generated by KMEP would be deductible in the
case of a fully taxable disposition of such KMEP Common Units to an unrelated
party. The passive activity loss rules are applied after other applicable
limitations on deductions such as the at risk rules and the basis limitation.
    
 
   
    There is no guidance as to whether suspended passive activity losses of
Santa Fe Common Units will be available to offset passive activity income that
is allocated to a former Santa Fe Common Unit holder from KMEP activities after
the Transaction. The IRS may contend that KMEP is not the same partnership as
Santa Fe and, accordingly, the passive loss limitations will not allow use of
such losses until such time as all of such holder's KMEP Common Units are sold.
A KMEP Common Unit holder may take the position, however, that KMEP should be
deemed a continuation of Santa Fe for this purpose such that any suspended Santa
Fe losses would be available to offset KMEP taxable income allocated to such
holder. Because of the lack of guidance with respect to this issue, Morrison &
Hecker is unable to opine as to whether suspended passive activity losses
arising from Santa Fe activities will be available to offset KMEP taxable income
allocated to a former Santa Fe Common Unit holder following the Transaction.
    
 
    The IRS has announced that Treasury Regulations will be issued that
characterize net passive income from a publicly traded partnership as investment
income for purposes of the limitations on the deductibility of investment
interest.
 
ALLOCATION OF KMEP INCOME, GAIN, LOSS AND DEDUCTION
 
    In general, if KMEP has a net profit, the KMEP Partnership Agreement
provides that items of income, gain, loss and deduction will be allocated
between the KM General Partner and the KMEP Common Unit holders in accordance
with their respective percentage interests in KMEP. The KMEP Partnership
Agreement also provides for a special allocation of gross income or gain to the
KM General Partner to the extent necessary to support the incentive cash
distributions payable to it. If KMEP has a net loss, items of income, gain, loss
and deduction will be allocated, first, to the KM General Partner and the KMEP
Common Unit holders to the extent of their positive book capital accounts, and
second, to the KM General Partner. On a liquidating sale of assets, the KMEP
Partnership Agreement provides separate gain and loss allocations, designed to
the extent possible, (i) to eliminate a deficit in any partner's book
 
                                      139
<PAGE>
capital account and (ii) to produce book capital accounts which, when followed
on liquidation, will result in each holder of KMEP Common Units recovering
Unrecovered Capital, and a distributive share of any additional value. See
"--Description of KMEP Partnership Agreement--Cash Distribution Policy--
Distributions of Cash from Operations."
 
    Under Section 704(b), a partnership's allocation of any item of income,
gain, loss or deduction to a partner will not be given effect for federal income
tax purposes, unless it has "substantial economic effect," or is otherwise
allocated in accordance with the partner's interest in the partnership. If the
allocation does not satisfy this standard, it will be reallocated among the
partners on the basis of their respective interests in the partnership, taking
into account all facts and circumstances.
 
    Regulations under Section 704(b) delineate the circumstances under which the
IRS will view partnership allocations as having an "economic effect" that is
"substantial." Generally, for an allocation to have "economic effect" under the
Regulations (a) the allocation must be reflected as an appropriate increase or
decrease in a capital account maintained for each partner in accordance with
specific rules set forth in the Regulations, (b) liquidating distributions
(including complete redemptions of a partner's interest in the partnership)
must, throughout the term of the partnership, be made in accordance with the
partner's positive capital account balances and (c) any partner with a deficit
balance in such partner's capital account following a liquidating distribution
must be unconditionally obligated (either by contract or state law) to restore
the amount of such deficit to the partnership within a limited period of time.
 
    If the first two of these requirements are met, but the partner to whom an
allocation of loss or deduction is made is not obligated to restore the full
amount of any deficit balance in such partner's capital account upon liquidation
of the partnership, an allocation of loss or deduction may still have economic
effect, if (1) the agreement contains a "qualified income offset" provision, and
(2) the allocation either does not (i) cause a deficit balance in a partner's
capital account (reduced by certain anticipated adjustments, allocations and
distributions specified in the Regulations) as of the end of the partnership
taxable year to which the allocation relates or (ii) increase any such deficit
balance in this specially adjusted capital account by more than the partner's
unpaid obligation to contribute additional capital to the partnership. A
qualified income offset provision requires that in the event of any unexpected
distribution (or specified adjustments or allocations) there must be an
allocation of income or gain to the distributees that eliminates the resulting
capital account deficit as quickly as possible. (This rule is referred to herein
as the "Alternate Economic Effect Rule.")
 
   
    The Regulations require that capital accounts be (1) credited with the fair
market value of property contributed to the partnership (net of liabilities
encumbering the contributed property that the partnership is considered to
assume or take subject to pursuant to Section 752) ("Contributed Property"), (2)
credited with the amount of cash contributed to the partnership and (3) adjusted
by items of depreciation, amortization, gain and loss attributable to
partnership properties that have been computed by taking into account the book
value (rather than tax basis) of such properties. (As a result, such capital
accounts are often referred to as "book" capital accounts.) A partner's capital
account must also be reduced by (i) the amount of money distributed to such
partner by the partnership, (ii) the fair market value of property distributed
to such partner by the partnership (net of liabilities encumbering the
distributed property that such holder is considered to assume or take subject to
pursuant to Section 752) and (iii) a distributive share of certain partnership
expenses that are neither deductible nor amortizable.
    
 
   
    The Book-Tax Disparities created by crediting capital accounts with the
value of Contributed Properties are eliminated through tax allocations that
cause the partner whose book capital account reflects unrealized gain or loss to
bear the corresponding tax benefit or burden associated with the recognition of
such unrealized gain or loss in accordance with the principles of Section
704(c). The allocations of these tax items that differ in amount from their
correlative book items do not have economic effect, because they are not
reflected in the partners' capital accounts. The Regulations provide, however,
that the allocations
    
 
                                      140
<PAGE>
of such items will be deemed to be in accordance with the partners' interests in
the partnership if they are made in accordance with the Section 704(c)
Regulations.
 
   
    In addition, the Regulations permit the partners' capital accounts to be
increased or decreased to reflect the revaluation of partnership property (at
fair market value) if the adjustments are made for a substantial non-tax
business purpose in connection with a contribution or distribution of money or
other property in consideration for the acquisition or relinquishment of an
interest in the partnership, such as upon an additional issuance of KMEP Common
Units by KMEP in the Transaction. These adjustments may also create Book-Tax
Disparities, which the Regulations require to be eliminated through tax
allocations in accordance with Section 704(c) principles.
    
 
    An allocation must not only have economic effect to be respected, but that
economic effect must also be "substantial." The economic effect of an allocation
is substantial if there is a reasonable possibility that the allocation will
affect substantially the dollar amounts to be received by the partners from the
partnership, independent of tax consequences. As a general matter, however, the
economic effect of an allocation is not substantial if, at the time the
allocation is adopted, the after-tax economic consequences of at least one
partner may, in present value terms, be enhanced by such allocation, but there
is a strong likelihood that the after-tax economic consequences of no other
partner will, in present value terms, be substantially diminished by such
allocation.
 
   
    The KMEP Partnership Agreement provides that a capital account be maintained
for each partner, that the capital accounts generally be maintained in
accordance with the applicable tax accounting principles set forth in the
Regulations, and that all allocations to a partner be reflected by an
appropriate increase or decrease in the partner's capital account. In addition,
distributions upon liquidation of KMEP are to be made in accordance with
positive capital account balances. The limited partners are not required to
contribute capital to KMEP to restore deficit balances in their capital accounts
upon liquidation of KMEP. However, the KMEP Partnership Agreement contains
qualified income offset and minimum gain chargeback provisions, which under the
Section 704(b) Regulations comply with the Alternate Economic Effect Rule and
will obviate the requirement to restore negative capital accounts. The KMEP
Partnership Agreement provides that any losses or deductions otherwise allocable
to a holder of KMEP Common Units that have the effect of creating a deficit
balance in such holder's capital account (as specially adjusted) will be
reallocated to the KM General Partner.
    
 
   
    In general, KMEP's items of income, gain, loss and deduction will be
allocated, for book and tax purposes, among the KM General Partner, in its
capacity as general partner, and the holders of KMEP Common Units in the same
proportion that Available Cash is distributed (as between the KM General Partner
and the holders of KMEP Common Units) in respect of such taxable year. If
distributions of Available Cash are not made in respect of a particular taxable
year, such items will be allocated among the partners in accordance with their
respective percentage interests. Except as discussed below, items of income,
gain, loss and deduction allocated to the holders of KMEP Common Units, in the
aggregate, will be allocated among the holders of KMEP Common Units in
accordance with the number of KMEP Common Units held by such KMEP Common Unit
holder. Special tax (but not book) allocations will be made to reflect Book-Tax
Disparities with respect to Contributed Properties. The KMEP Partnership
Agreement also provides for certain special allocations of income and gain as
required by the qualified income offset and minimum gain chargeback provisions.
In addition, the KM General Partner is empowered by the KMEP Partnership
Agreement to allocate various KMEP items other than in accordance with the
percentage interests of the KM General Partner and the holders of KMEP Common
Units when, in its judgment, such special allocations are necessary to comply
with applicable provisions of the Code and the Regulations and to achieve
uniformity of KMEP Common Units. See "--Uniformity of KMEP Common Units."
    
 
    With respect to Contributed Property, the KMEP Partnership Agreement
provides that, for federal income tax purposes, items of income, gain, loss and
deduction shall first be allocated among the partners
 
                                      141
<PAGE>
   
in a manner consistent with Section 704(c). In addition, the KMEP Partnership
Agreement provides that items of income, gain, loss and deduction attributable
to any properties when, upon the subsequent issuance of any KMEP Common Units,
KMEP has adjusted the book value of such properties to reflect unrealized
appreciation or depreciation in value from the later of the KMEP Partnerships'
acquisition date for such properties or the latest date of a prior issuance of
KMEP Common Units ("Adjusted Property") shall be allocated for federal income
tax purposes in accordance with Section 704(c) principles. Thus, deductions for
the depreciation of Contributed Property and Adjusted Property will be specially
allocated to the non-contributing KMEP Common Unit holders and gain or loss from
the disposition of such property attributable to the Book-Tax Disparity will be
allocated to the contributing KMEP Common Unit holders so that the
non-contributing KMEP Common Unit holders will be allowed, to the extent
possible, cost recovery and depreciation deductions and will be allocated gain
or loss from the sale of assets generally as if they had purchased a direct
interest in KMEP's assets.
    
 
    The KMEP Partnership Agreement also requires gain from the sale of
properties of KMEP that is characterized as recapture income to be allocated
among the holders of KMEP Common Units and the KM General Partner (or its
successors) in the same manner in which such partners were allocated the
deductions giving rise to such recapture income. Final Treasury Regulations
under Section 1245 provide that depreciation recapture will be specially
allocated based on the allocation of the deductions giving rise to such
recapture income, as provided for in the KMEP Partnership Agreement.
 
   
    Items of gross income and deduction will be allocated in a manner intended
to eliminate Book-Tax Disparities, if any, that are not eliminated by Section
704(c) allocations as a result of the application of the Ceiling Rule with
respect to Contributed Property or Adjusted Property. Such Curative Allocations
of gross income and deductions to preserve the uniformity of the income tax
characteristics of KMEP Common Units will not have economic effect, because they
will not be reflected in the capital accounts of the holders of KMEP Common
Units. However, such allocations will eliminate Book-Tax Disparities and are
thus consistent with the Regulations under Section 704(c).
    
 
   
    With the exception of certain conventions adopted by KMEP with respect to
administration of the Section 754 election and the attendant Section 743(b)
basis adjustments discussed at "--Tax Treatment of Operations--Section 754
Election"; and allocation of the effect of unamortizable Section 197 Book-Up
amounts and common inside basis, allocations under the KMEP Partnership
Agreement will be given effect for federal income tax purposes in determining a
holder's distributive share of an item of income, gain, loss or deduction. There
are, however, uncertainties in the Regulations relating to allocations of
partnership income, and KMEP Common Unit holders should be aware that some of
the allocations in the KMEP Partnership Agreement may be successfully challenged
by the IRS. See "--Tax Treatment of Operations--Section 754 Election--" and
"--Uniformity of KMEP Common Units" for a discussion of such allocations.
    
 
TAX TREATMENT OF OPERATIONS
 
    ACCOUNTING METHOD AND TAXABLE YEAR.  KMEP has adopted and will maintain the
calendar year as its taxable year and the accrual method of accounting for
federal income tax purposes.
 
   
    TAX BASIS, DEPRECIATION AND AMORTIZATION.  Under Section 723 of the Code,
after the Transaction KMEP assets will have an aggregate tax basis that is equal
to: (a) the aggregate tax basis of the assets held by Santa Fe and KMEP (prior
to the Transaction); (b) any gain recognized by Santa Fe Common Unit holders who
receive Fractional Unit Payments; and (c) the amounts paid to the SF General
Partner. The tax bases for the KMEP assets will be used for purposes of
computing depreciation and cost recovery deductions and, ultimately, after
adjustment for intervening depreciation or cost recovery deductions, gain or
loss on the disposition of such assets.
    
 
   
    KMEP intends to allocate the capital account value among KMEP's assets after
the Transaction based upon their relative fair market values established by an
independent appraisal. Any amount in excess of the
    
 
                                      142
<PAGE>
fair market values of specific tangible assets may constitute non-amortizable
intangible assets (including goodwill).
 
   
    KMEP and the KMEP Operating Partnerships will have tangible assets of
substantial value (including the pipelines and related equipment). A significant
portion of the assets were placed in service prior to the effective dates of the
accelerated cost recovery system and will be depreciated over a 17 1/2 year
period on a declining balance method. The KM General Partner will depreciate
certain assets using the accelerated methods provided for under Section 168 of
the Code. In addition, KMEP will use accelerated methods provided for under
Section 167 of the Code to depreciate certain other assets during the early
years of the depreciable lives of those assets, and then elect to use the
straight line method in subsequent years. Because of the Section 704(c)
allocations, the amount of tax depreciation allocated to a holder of a KMEP
Common Unit is dependent, in part, on the fair market value of the partnership's
assets subject to Curative Allocations as established by the KM General Partner
at the time of the Transaction.
    
 
   
    The tax basis of goodwill and most other intangible assets used in a trade
or business acquired after August 10, 1993 (or prior to that time in certain
events), may be amortized over 15 years. KMEP will not amortize the goodwill, if
any, received in the Transaction for tax capital account or income tax purposes
because of the Step-in-the Shoes and Anti-Churning rules. See "--Tax
Consequences of the Transaction to Both KMEP and Santa Fe Common Unit
Holders--Section 197 Intangibles." However, see "--Section 754 Election" with
respect to the amortization of Section 743(b) adjustments allocated to goodwill
attributable to periods after the Transaction. The IRS may challenge either the
fair market values or the useful lives assigned to such assets. If any such
challenge or characterization were successful, the deductions allocated to a
holder of KMEP Common Units in respect of such assets would be reduced or
eliminated and a KMEP Common Unit holder's share of taxable income from KMEP
would be increased accordingly. Any such increase could be material.
    
 
    If KMEP disposes of depreciable property by sale, foreclosure or otherwise,
all or a portion of any gain (determined by reference to the amount of
depreciation previously deducted and the nature of the property) may be subject
to the recapture rules and taxed as ordinary income rather than capital gain.
Similarly, a partner that has taken cost recovery or depreciation deductions
with respect to property owned by KMEP may be required to recapture such
deductions upon a sale of such partner's interest in KMEP. See "--Allocation of
KMEP Income, Gain, Loss and Deduction" and "--Disposition of KMEP Common
Units--Recognition of Gain or Loss."
 
    Costs incurred in organizing the KMEP Partnerships may be amortized over any
period selected by the KMEP Partnerships not shorter than 60 months. The costs
incurred in promoting the issuance of KMEP Common Units must be capitalized and
cannot be deducted currently, ratably or upon termination of KMEP. There are
uncertainties regarding the classification of costs as organization expenses,
which may be amortized, and as syndication expenses which may not be amortized.
 
   
    SECTION 754 ELECTION.  KMEP has previously made a Section 754 election.
After the Transaction it is possible that 50% or more of the capital and profits
interests in KMEP will have changed ownership causing a technical termination of
the partnership under Section 708. Accordingly, KMEP will again make the
election permitted by Section 754 for the taxable year that includes the
Transaction. This election is irrevocable without the consent of the IRS. The
election will generally permit a purchaser of, or a holder of Santa Fe Common
Units exchanging such Santa Fe Common Units for, KMEP Common Units to adjust
such purchaser's or such holder's share of the basis in KMEP's properties
("Common Basis") pursuant to Section 743(b) to the basis of such Unit holder's
KMEP Common Units, which would generally be the purchase price if such holder
purchased such KMEP Common Units for cash. In the case of KMEP Common Units
purchased in the market, the Section 743(b) adjustment acts in concert with
Section 704(c) allocations (and Curative Allocations, if respected) in providing
the purchaser of such KMEP Common Units with the equivalent of a fair market
value Common Basis. See "--Allocation of KMEP Income, Gain, Loss and Deduction."
The Section 743(b) adjustment is attributed solely to a purchaser of KMEP
    
 
                                      143
<PAGE>
Common Units and is not added to the bases of KMEP's assets associated with all
of the holders of KMEP Common Units. (For purposes of this discussion, a KMEP
Common Unit holder's inside basis in KMEP's assets will be considered to have
two components: (1) the partner's share of KMEP's actual basis in such assets
("Common Basis") and (2) the partner's Section 743(b) adjustment allocated to
each such asset.)
 
   
    A Section 754 election is advantageous if the transferee's basis in KMEP
Common Units is higher than KMEP's aggregate Common Basis allocable to that
portion of its assets represented by such units immediately prior to the
transfer. In such case, pursuant to the election, the transferee would take a
new and higher basis in the transferee's share of KMEP's assets for purposes of
calculating, among other items, depreciation deductions and the applicable share
of any gain or loss on a sale of KMEP's assets. Conversely, a Section 754
election is disadvantageous if the transferee's basis in such KMEP Common Units
is lower than KMEP's aggregate Common Basis allocable to that portion of its
assets represented by such units immediately prior to the transfer. Thus, the
amount that a holder of KMEP Common Units will be able to obtain upon the sale
of KMEP Common Units may be affected either favorably or adversely by the
election. A constructive termination of KMEP will also cause a Section 708
termination of the Operating Partnerships. Such a termination could also result
in penalties or loss of basis adjustments under Section 754, if the KM General
Partner were unable to determine that the termination had occurred and,
therefore, did not timely file a tax return or make appropriate Section 754
elections for the "new" KMEP.
    
 
   
    There will be no Section 743(b) adjustment attributable solely to the
Transaction because the Santa Fe holders of KMEP Common Units are effectively
contributing the SF Operating Partnership LP Interest in exchange for KMEP
Common Units in a Section 721 transaction without an increase in basis. However,
a former Santa Fe Common Unit holder will continue to receive the benefit of any
Section 743(b) adjustment attributable to a prior purchase of such Santa Fe
Common Units. However, this benefit will be deferred to an extent because of the
constructive termination of Santa Fe and the SF Operating Partnership. In
addition, there will be net Curative allocations to some holders of KMEP Common
Units. See "--Tax Consequences of Holding KMEP Common Units--Capital Accounts
Valuation of Assets, and Curative Allocations under Section 704(c)", "--Section
197 Intangibles" and "--Constructive Termination of Partnership."
    
 
   
    Proposed Treasury Regulation Section 1.168-2(n) generally requires the
Section 743(b) adjustment attributable to recovery property to be depreciated as
if the total amount of such adjustment were attributable to newly-acquired
recovery property placed in service when the transfer occurs. Under Treasury
Regulation Section 1.167(c)-1(a)(6), a Section 743(b) adjustment attributable to
property subject to depreciation under Section 167 rather than cost recovery
deductions under Section 168 is generally required to be depreciated using
either the straight-line method or the 150% declining balance method. Although
Morrison & Hecker is unable to opine as to the validity of such an approach,
KMEP intends to depreciate the portion of a Section 743(b) adjustment
attributable to unrealized appreciation in the value of KMEP's property (to the
extent of any unamortized Book-Tax Disparity) using a rate of depreciation
derived from the depreciation method and useful life applied to the Common Basis
of such property, despite its inconsistency with Proposed Treasury Regulation
Section 1.168-2(n) and Treasury Regulation Section 1.167(c)-1(a)(6). If an asset
is not subject to depreciation or amortization, no Section 743(b) adjustment
would be available to that extent. See "--Tax Consequences of Holding and
Disposing of KMEP Common Units--Section 197 Intangibles." If the KM General
Partner determines that such position cannot reasonably be taken, KMEP may adopt
a depreciation convention under which all purchasers acquiring KMEP Common Units
in the same month would receive depreciation, whether attributable to Common
Basis or Section 743(b) basis, based upon the same applicable rate as if they
had purchased a direct interest in KMEP's property. Such an aggregate approach,
or any other method required as a result of an IRS examination, may result in
lower annual depreciation deductions than would otherwise be allowable to
certain holders of KMEP Common Units. See "--Uniformity of KMEP Common Units."
    
 
                                      144
<PAGE>
    The allocation of the Section 743(b) adjustment must be made in accordance
with the principles of Section 1060. Based on these principles, the IRS may seek
to reallocate some or all of any Section 743(b) adjustment not so allocated by
KMEP to intangible assets that have a 15 year amortization period, which is not
eligible for accelerated depreciation methods generally applicable to the assets
of KMEP.
 
    The calculations involved in the Section 754 election are complex and will
be made by KMEP on the basis of certain assumptions as to the value of KMEP
assets and other matters. There is no assurance that the determinations made by
the KM General Partner will not be successfully challenged by the IRS and that
the deductions attributable to them will not be disallowed or reduced.
 
   
    VALUATION OF PROPERTY OF KMEP.  The federal income tax consequences of the
acquisition, ownership and disposition of KMEP Common Units will depend in part
on estimates by the KM General Partner of the relative fair market values, and
determinations of the tax basis, of the assets of KMEP. Although the KM General
Partner may from time to time consult with professional appraisers with respect
to valuation matters, many of the relative fair market value estimates will be
made solely by the KM General Partner. These estimates are subject to challenge
and will not be binding on the IRS or the courts. In the event the
determinations of fair market value are subsequently found to be incorrect, the
character and amount of items of income, gain, loss, deductions or credits
previously reported by KMEP Common Unit holders might change, and KMEP Common
Unit holders might be required to amend their previously filed tax returns or to
file claims for refunds.
    
 
    MONT BELVIEU FRACTIONATOR.  OLP-A owns all of the capital stock of a
corporation that owns an indirect interest in the Mont Belvieu Fractionator. As
a corporation, it will be subject to entity-level taxation for federal and state
income tax purposes. KMEP, as its shareholder, will include in its income any
amounts distributed to it by such corporation to the extent of such
corporation's current and accumulated earnings and profits. The KM General
Partner estimates that a portion of the cash distributions to KMEP by such
corporation will be treated as taxable dividends.
 
   
    ALTERNATIVE MINIMUM TAX.  Each holder of KMEP Common Units will be required
to take into account such holder's distributive share of any items of KMEP
income, gain or loss for purposes of the alternative minimum tax
("AMT")--currently a tax of 26% on the first $175,000 of alternative minimum
taxable income in excess of the exemption amount and 28% on any additional
alternative minimum taxable income. Alternative minimum taxable income is
calculated using the 150% declining balance method of depreciation with respect
to personal property and 40-year straight-line depreciation for real property,
compared to the alternative straight line and accelerated methods provided for
under Section 168, which KMEP will use in computing its income for regular
federal income tax purposes. A KMEP Common Unit holder's AMT income derived from
KMEP may be higher than such holder's share of KMEP net income, because KMEP may
use more accelerated methods of depreciation for purposes of computing regular
federal taxable income or loss than are available for AMT income purposes.
Prospective holders of KMEP Common Units should consult with their tax advisors
as to the impact of an investment in KMEP Common Units on their liability for
the alternative minimum tax.
    
 
DISPOSITION OF KMEP COMMON UNITS
 
   
    RECOGNITION OF GAIN OR LOSS.  Gain or loss will be recognized on a sale of
KMEP Common Units equal to the difference between the amount realized and a
holder's tax basis for the KMEP Common Units sold. A holder's amount realized
will be measured by the sum of the cash received or the fair market value of
other property received, plus such holder's share of KMEP nonrecourse
liabilities. Because the amount realized includes a KMEP Common Unit holder's
share of KMEP nonrecourse liabilities, the gain recognized on the sale of KMEP
Common Units could result in a tax liability in excess of any cash received from
such sale.
    
 
                                      145
<PAGE>
   
    The IRS has ruled that a partner acquiring interests in a partnership in
separate transactions at different prices must maintain an aggregate adjusted
tax basis in a single partnership interest and that, upon sale or other
disposition of some of the interests, a portion of such aggregate tax basis must
be allocated to the interests sold on the basis of some equitable apportionment
method. The ruling is unclear as to how the holding period is affected by this
aggregation concept. If this ruling is applicable to the holders of KMEP Common
Units, the aggregation of tax bases of a holder of KMEP Common Units effectively
prohibits such holder from choosing among KMEP Common Units with varying amounts
of unrealized gain or loss as would be possible in a stock transaction. Thus,
the ruling may result in an acceleration of gain or deferral of loss on a sale
of a portion of a holder's KMEP Common Units. It is not clear whether the ruling
applies to publicly traded partnerships, such as KMEP, the interests in which
are evidenced by separate Common Units and, accordingly, Morrison & Hecker is
unable to opine as to the effect such ruling will have on a holder of KMEP
Common Units. A holder of KMEP Common Units considering the purchase of
additional KMEP Common Units or a sale of KMEP Common Units purchased at
differing prices (including a Santa Fe Common Unit holder that acquired KMEP
Common Units other than pursuant to the Transaction) should consult a tax
advisor as to the possible consequences of such ruling.
    
 
    Prior KMEP distributions in excess of cumulative net taxable income in
respect of a KMEP Common Unit which decreased a holder's tax basis in such KMEP
Common Units will, in effect, become taxable income if the KMEP Common Unit is
sold at a price greater than the holder's tax basis in such KMEP Common Unit,
even if the price is less than its original cost.
 
   
    Should the IRS successfully contest the convention used by KMEP to amortize
only a portion of the Section 743(b) adjustment (described under "--Tax
Treatment of Operations--Section 754 Election") attributable to an amortizable
Section 197 Intangible after a sale of KMEP Common Units, a holder of KMEP
Common Units could realize more gain from the sale of its KMEP Common Units than
if such convention had been respected. In that case, the holder of KMEP Common
Units may have been entitled to additional deductions against income in prior
years, but may be unable to claim them, with the result of greater overall
taxable income than appropriate. Morrison & Hecker is unable to opine as to the
validity of the convention, because of the lack of specific regulatory authority
for its use.
    
 
   
    TREATMENT OF SHORT SALES.  Under the 1997 Act, a taxpayer is treated as
having sold an "appreciated" partnership interest (one in which gain would be
recognized if such interest were sold), if such taxpayer or related persons
entered into one or more positions with respect to the same or substantially
identical property which, for some period, substantially eliminated both the
risk of loss and opportunity for gain on the appreciated financial position
(including selling "short against the box" transactions). Holders of KMEP Common
Units should consult with their tax advisers in the event they are considering
entering into a short sale transaction or any other risk arbitrage transaction
involving KMEP Common Units.
    
 
   
    A holder whose KMEP Common Units are loaned to a "short seller" to cover a
short sale of KMEP Common Units will be considered as having transferred
beneficial ownership of those KMEP Common Units and will, thus, no longer be a
partner with respect to those KMEP Common Units during the period of the loan.
As a result, during this period, any KMEP income, gain, deductions, losses or
credits with respect to those KMEP Common Units would appear not to be
reportable by the holders thereof, any cash distributions received by such
holders with respect to those KMEP Common Units would be fully taxable and all
of such distributions would appear to be treated as ordinary income. The IRS may
also contend that a loan of KMEP Common Units to a "short seller" constitutes a
taxable exchange. If this contention were successfully made, a lending holder of
KMEP Common Units may be required to recognize gain or loss. HOLDERS OF KMEP
COMMON UNITS DESIRING TO ASSURE THEIR STATUS AS PARTNERS SHOULD MODIFY THEIR
BROKERAGE ACCOUNT AGREEMENTS, IF ANY, TO PROHIBIT THEIR BROKERS FROM BORROWING
THEIR KMEP COMMON UNITS.
    
 
                                      146
<PAGE>
   
    CHARACTER OF GAIN OR LOSS.  Generally, gain or loss recognized by a holder
of KMEP Common Units (other than a "dealer" in KMEP Common Units) on the sale or
exchange of a KMEP Common Unit will be taxable as capital gain or loss. For
transactions after July 29, 1997, the 1997 Act lengthens the holding period
required for long-term capital gain treatment to 18 months in order to qualify a
gain for an effective maximum tax rate of 20%. The 1997 Act also creates a
mid-term capital gain concept for assets held for more than 12 months, but not
more than 18 months, for which the maximum tax rate is 28%. Capital assets sold
at a profit within 12 months of purchase would result in short term capital
gains taxed at ordinary income tax rates. This holding period will include any
pre-Transaction KMEP Common Unit holder's prior holding period. For a discussion
of a former Santa Fe Common Unit holder's holding period see "Tax Consequences
of the Exchange and Distribution--Basis and Holding Period of KMEP Common
Units." However, as to Santa Fe Common Unit holders the portion of such KMEP
Common Units, or a portion of each KMEP Common Unit, attributable to assets that
were neither capital assets nor Section 1231 assets in the hands of Santa Fe or
the SF Operating Partnership, will have a holding period commencing on the day
following the Closing Date. See "--Tax Consequences of the Exchange and
Distributions." Any gain or loss, however, will be separately computed and taxed
as ordinary income or loss under Section 751 to the extent attributable to
assets giving rise to depreciation recapture or other "unrealized receivables"
or to "inventory" owned by KMEP. The term "unrealized receivables" also includes
potential recapture items other than depreciation recapture. Ordinary income
attributable to unrealized receivables, inventory and depreciation recapture may
exceed net taxable gain realized upon the sale of a KMEP Common Unit and may be
recognized even if there is a net taxable loss realized on the sale of a KMEP
Common Unit. Any loss recognized on the sale of units will generally be a
capital loss. Thus, a holder of KMEP Common Units may recognize both ordinary
income and a capital loss upon a disposition of units. Net capital loss may
offset no more than $3,000 of ordinary income in the case of individuals and may
only be used to offset capital gain in the case of a corporation.
    
 
   
    ALLOCATIONS BETWEEN TRANSFERORS AND TRANSFEREES.  In general, KMEP's taxable
income and losses will be determined annually and will be prorated on a monthly
basis and subsequently apportioned among the holders in proportion to the number
of KMEP Common Units owned by them as of the opening of the first business day
of the month to which the income and losses relate even though KMEP Common Unit
holders may dispose of their units during the month in question. Gain or loss
realized on a sale or other disposition of partnership assets other than in the
ordinary course of business shall be allocated among the KMEP Common Unit
holders of record as of the opening of the NYSE on the first business day of the
month in which such gain or loss is recognized. As a result of this monthly
allocation, a holder of KMEP Common Units transferring units in the open market
may be allocated income, gain, loss, deduction, and credit accrued after the
transfer.
    
 
    The use of the monthly conventions discussed above may not be permitted by
existing Treasury Regulations and, accordingly, Morrison & Hecker is unable to
opine on the validity of the method of allocating income and deductions between
the transferors and the transferees of KMEP Common Units. If a monthly
convention is not allowed by the Treasury Regulation (or only applies to
transfers of less than all of the holder's KMEP Common Units), taxable income or
losses of KMEP might be reallocated among the holders of KMEP Common Units. The
KM General Partner is authorized to review KMEP's method of allocation between
transferors and transferees (as well as among partners whose interests otherwise
vary during a taxable period) to conform to a method permitted by future
Treasury Regulations.
 
   
    A holder who owns KMEP Common Units at any time during a quarter and who
disposes of such KMEP Common Units prior to the record date set for a
distribution with respect to such quarter will be allocated items of KMEP income
and gain attributable to such quarter for the months during which such KMEP
Common Units were owned but will not be entitled to receive such cash
distribution.
    
 
    NOTIFICATION REQUIREMENTS.  A holder of KMEP Common Units who sells or
exchanges KMEP Common Units is required to notify KMEP in writing of such sale
or exchange within 30 days of the sale or exchange and in any event no later
than January 15 of the year following the calendar year in which the
 
                                      147
<PAGE>
sale or exchange occurred. KMEP is required to notify the IRS of such
transaction and to furnish certain information to the transferor and transferee.
However, these reporting requirements do not apply with respect to a sale by an
individual who is a citizen of the United States and who effects such sale
through a broker. Additionally, a transferor and a transferee of a KMEP Common
Unit will be required to furnish statements to the IRS, filed with their income
tax returns for the taxable year in which the sale or exchange occurred, which
set forth the amount of the consideration received for such KMEP Common Unit
that is allocated to goodwill or going concern value of KMEP. Failure to satisfy
such reporting obligations may lead to the imposition of substantial penalties.
 
   
    CONSTRUCTIVE TERMINATION.  KMEP and the Operating Partnerships will be
considered to have been terminated if there is a sale or exchange of 50% or more
of the total interests in partnership capital and profits within a 12-month
period. A constructive termination results in the closing of a partnership's
taxable year for all partners and the "old" KMEP (before termination) is deemed
to have contributed its assets to "new" KMEP and distributed interests in "new"
KMEP to the holders of KMEP Common Units. "New" KMEP is then treated as a new
partnership. A constructive termination of KMEP will also cause a Section 708
termination of the Operating Partnerships. Such a termination could also result
in penalties or loss of basis adjustments under Section 754, if KMEP were unable
to determine that the termination had occurred and, therefore, did not timely
file a tax return and make the appropriate Section 754 elections for the "new"
KMEP.
    
 
    In the case of a holder of KMEP Common Units reporting on a fiscal year
other than a calendar year, the closing of a tax year of KMEP may result in more
than 12 months' taxable income or loss of KMEP being includable in its taxable
income for the year of termination. New tax elections required to be made by
KMEP, including a new election under Section 754, must be made subsequent to the
constructive termination. A constructive termination would also result in a
deferral of KMEP deductions for depreciation and amortization. In addition, a
termination might either accelerate the application of or subject KMEP to any
tax legislation enacted with effective dates after the closing of the
Transaction.
 
    ENTITY-LEVEL COLLECTIONS.  If KMEP is required under applicable law to pay
any federal, state or local income tax on behalf of any holder of KMEP Common
Units or the KM General Partner or former holders of KMEP Common Units, the KM
General Partner is authorized to pay such taxes from KMEP funds. Such payments,
if made, will be deemed current distributions of cash to such KMEP Common Unit
holder or the KM General Partner as the case may be. The KM General Partner is
authorized to amend the KMEP Partnership Agreement in the manner necessary to
maintain uniformity of intrinsic tax characteristics of KMEP Common Units and to
adjust subsequent distributions so that after giving effect to such deemed
distributions, the priority and characterization of distributions otherwise
applicable under the KMEP Partnership Agreement is maintained as nearly as is
practicable. Payments by KMEP as described above could give rise to an
overpayment of tax on behalf of an individual partner in which event, the
partner could file a claim for credit or refund.
 
UNIFORMITY OF KMEP COMMON UNITS
 
   
    Since KMEP cannot trace the chain of ownership of any particular KMEP Common
Unit, it is unable to track the economic and tax characteristics related to
partciular KMEP Common Units from owner to owner. Consequently, uniformity of
the economic and tax characteristics of the KMEP Common Units to a holder of
former Santa Fe Common Units or a purchaser of KMEP Common Units must be
maintained. In order to achieve uniformity, compliance with a number of federal
income tax requirements, both statutory and regulatory, could be substantially
diminished. For example, a lack of uniformity can result from a literal
application of Proposed Treasury Regulation Section 1.168-2(n) and Treasury
Regulation Section 1.167(c)-1(a)(6) and from the effect of the Ceiling Rule on
KMEP's ability to make allocations to eliminate Book-Tax Disparities
attributable to Contributed Properties and partnership property that has been
revalued and reflected in the partners' capital accounts. If the IRS were to
challenge such conventions intended to achieve uniformity and such challenge
were successful, the tax consequences of holding
    
 
                                      148
<PAGE>
   
particular KMEP Common Units could differ. Any such non-uniformity could have a
negative impact on the value of KMEP Common Units.
    
 
   
    KMEP intends to depreciate the portion of a Section 743(b) adjustment
attributable to unrealized appreciation in the value of Contributed Property or
Adjusted Property (to the extent of any unamortized Book-Tax Disparity) using a
rate of depreciation derived from the depreciation method and useful life
applied to the Common Basis of such property, despite its inconsistency with
Proposed Treasury Regulation Section 1.168-2(a) and Treasury Regulation Section
1.167(c)-1(a)(6). See "--Tax Treatment of Operations--Section 754 Election" and
"--Tax Consequences of Holding and Disposing of Common Units--Section 197
Intangibles." If KMEP determines that such a position cannot reasonably be
taken, KMEP may adopt a depreciation convention under which all purchasers
acquiring KMEP Common Units in the same month would receive depreciation,
whether attributable to Common Basis or Section 743(b) basis, based upon the
same applicable rate as if they had purchased a direct interest in KMEP's
property. If such an aggregate approach is adopted, it may result in lower
annual depreciation deductions than would otherwise be allowable to certain
holders of KMEP Common Units and risk the loss of depreciation deductions not
taken in the year that such deductions are otherwise allowable. This convention
will not be adopted if KMEP determines that the loss of depreciation deductions
would have a material adverse effect on a holder of KMEP Common Units. If KMEP
chooses not to utilize this aggregate method, KMEP may use any other reasonable
depreciation convention to preserve the uniformity of the intrinsic tax
characteristics of KMEP Common Units that would not have a material adverse
effect on the holders of KMEP Common Units. The IRS may challenge any method of
depreciating the Section 743(b) adjustment described in this paragraph. If such
a challenge were to be sustained, the uniformity of KMEP Common Units might be
affected.
    
 
   
    Items of income and deduction, including the effects of any unamortizable
intangibles under the Proposed Treasury Regulation Section 197-2(g)(1), will be
specially allocated in a manner that is intended to preserve the uniformity of
intrinsic tax characteristics among all KMEP Common Units, despite the
application of the Ceiling Rule to Contributed Properties and Adjusted
Properties. Such special allocations will be made solely for federal income tax
purposes. See "--Tax Consequences of Ownership of KMEP Common Units" and
"--Allocations of KMEP Income, Gain, Loss and Deduction."
    
 
TAX-EXEMPT ORGANIZATIONS AND CERTAIN OTHER INVESTORS
 
    Ownership of KMEP Common Units by certain tax-exempt entities, regulated
investment companies and foreign persons raises issues unique to such persons
and, as described below, may have substantially adverse tax consequences.
 
    Employee benefit plans and most other organizations exempt from federal
income tax (including IRAs and other retirement plans) are subject to federal
income tax on unrelated business taxable income in excess of $1,000, and each
such entity must file a tax return for each year in which it has more than
$1,000 of gross income included in computing unrelated business taxable income.
Substantially all of the taxable income derived by such an organization from the
ownership of a KMEP Common Unit will be unrelated business taxable income and
thus will be taxable to such a holder of KMEP Common Units at the maximum
corporate tax rate. Also, to the extent that KMEP holds debt financed property,
the disposition of a KMEP Common Unit could result in unrelated business taxable
income.
 
    Regulated investment companies are required to derive 90% or more of their
gross income from interest, dividends, gains from the sale of stocks or
securities or foreign currency or certain related sources. It is not anticipated
that any significant amount of KMEP's gross income will qualify as such income.
 
    Non-resident aliens and foreign corporations, trusts or estates which
acquire KMEP Common Units will be considered to be engaged in business in the
United States on account of ownership of KMEP Common Units and as a consequence
will be required to file federal tax returns in respect of their distributive
shares of KMEP income, gain, loss, deduction or credit and pay federal income
tax at regulate
 
                                      149
<PAGE>
rates on such income. Generally, a partnership is required to pay a withholding
tax on the portion of the partnership income which is effectively connected with
the conduct of a United States trade or business and which is allocable to the
foreign partners, regardless of whether any actual distributions have been made
to such partners. However, under procedural guidelines applicable to publicly
traded partnerships, KMEP has elected instead to withhold (or a broker holding
KMEP Common Units in street name will withhold) at the rate of 39.6% on actual
cash distributions made quarterly to foreign holders of KMEP Common Units. Each
foreign holder of KMEP Common Units must obtain a taxpayer identification number
from the IRS and submit that number to the Transfer Agent on a Form W-8 in order
to obtain credit for the taxes withheld. Subsequent adoption of Treasury
Regulations or the issuance of other administrative pronouncements may require
KMEP to change these procedures.
 
    Because a foreign corporation which owns KMEP Common Units will be treated
as engaged in a United States trade or business, such a holder may be subject to
United States branch profits tax at a rate of 30%, in addition to regular
federal income tax, on its allocable share of KMEP's earnings and profits (as
adjusted for changes in the foreign corporation's "U.S. net equity") that are
effectively connected with the conduct of a United States trade or business.
Such a tax may be reduced or eliminated by an income tax treaty between the
United States and the country with respect to which the foreign corporate holder
of KMEP Common Units is a "qualified resident."
 
   
    An interest in KMEP may also constitute a "United States Real Property
Interest" ("USRPI") under Section 897(c) of the Code. For this purpose, Treasury
Regulation Section 1.897-1(c)(2)(iv) treats a publicly traded partnership the
same as a corporation. Assuming that the KMEP Common Units continue to be
regularly traded on an established securities market, a foreign holder of KMEP
Common Units who sells or otherwise disposes of a KMEP Common Unit and who has
not held more than 5% in value of the KMEP Common Units, including KMEP Common
Units held by certain related individuals and entities, at any time during the
five-year period ending on the date of the disposition will qualify for an
exclusion from USRPI treatment and will not be subject to federal income tax on
gain realized on the disposition that is attributable to real property held by
KMEP. However, such holder may be subject to federal income tax on any gain
realized on the disposition that is treated as effectively connected with a
United States trade or business of the foreign holder of KMEP Common Units
(regardless of a foreign KMEP Common Unit holder's percentage interest in KMEP
or whether KMEP Common Units are regularly traded). A foreign holder of KMEP
Common Units will be subject to federal income tax on gain attributable to real
property held by KMEP if the holder held more than 5% in value of the KMEP
Common Units, including KMEP Common Units held by certain related individuals
and entities, during the five-year period ending on the date of the disposition
or if the KMEP Common Units were not regularly traded on an established
securities market at the time of the disposition. It is unclear whether a
similar rule applies to a former Santa Fe Common Unit holder that receives KMEP
Common Units in the Transaction and who held more than 5% in value of the Santa
Fe Common Units during the five-year period ending on the date of the
disposition. A foreign holder of KMEP Common Units will also be subject to
withholding under Section 1445 of the Code if such holder owns, including KMEP
Common Units held by certain related individuals and entities, more than a 5%
interest in KMEP. Under Section 1445 a transferee of a USRPI is required to
deduct and withhold a tax equal to 10% of the amount realized on the disposition
of a USRPI if the transferor is a foreign person.
    
 
ADMINISTRATIVE MATTERS
 
    KMEP INFORMATION RETURNS AND AUDIT PROCEDURES.  KMEP intends to furnish to
each holder of KMEP Common Units within 90 days after the close of each KMEP
taxable year, certain tax information, including a Schedule K-1, which sets
forth each holder's allocable share of KMEP's income, gain, loss, deduction and
credit. However, the Schedule K-1 and related information for the short tax
period ending on the date of the Transaction will be provided as soon as
practicable, but in all likelihood not within 90 days after the Transaction. The
KM General Partner will seek a closing agreement with the IRS to permit
 
                                      150
<PAGE>
such a delay; however, there is no assurance that an agreement will be reached
which would avoid any penalties for the delay in providing such filing
information. In preparing this information, which will generally not be reviewed
by counsel, the KM General Partner will use various accounting and reporting
conventions, some of which have been mentioned in the previous discussion, to
determine the respective KMEP Common Unit holder's allocable share of income,
gain, loss, deduction and credits. There is no assurance that any such
conventions will yield a result which conforms to the requirements of the Code,
the Regulations or administrative interpretations of the IRS. The KM General
Partner cannot assure a current or prospective holder of KMEP Common Units that
the IRS will not successfully contend in court that such accounting and
reporting conventions are impermissible.
 
    No assurance can be given that KMEP will not be audited by the IRS or that
tax adjustments will not be made. The rights of a holder of KMEP Common Units
owning less than a 1% profits interest in KMEP to participate in the income tax
audit process have been substantially reduced. Further, any adjustments in
KMEP's returns will lead to adjustments in KMEP Common Unit holder's returns and
may lead to audits of their returns and adjustments of items unrelated to KMEP.
Each KMEP Common Unit holder would bear the cost of any expenses incurred in
connection with an examination of such holder's personal tax return.
 
    Partnerships generally are treated as separate entities for purposes of
federal tax audits, judicial review of administrative adjustments by the IRS and
tax settlement proceedings. The tax treatment of partnership items of income,
gain, loss, deduction and credit are determined at the partnership level in a
unified partnership proceeding rather than in separate proceedings with the
partners. Under the 1997 Act, any penalty relating to an adjustment to a
partnership item is determined at the partnership level. The Code provides for
one partner to be designated as the "Tax Matters Partner" for these purposes.
The KMEP Partnership Agreement appoints the KM General Partner as the Tax
Matters Partner.
 
    The Tax Matters Partner will make certain elections on behalf of KMEP and
holders of KMEP Common Units and can extend the statute of limitations for
assessment of tax deficiencies against holders of KMEP Common Units with respect
to KMEP items. The Tax Matters Partner may bind a holder of KMEP Common Units
with less than a 1% profits interest in KMEP to a settlement with the IRS,
unless such holder elects, by filing a statement with the IRS, not to give such
authority to the Tax Matters Partner. The Tax Matters Partner may seek judicial
review (to which all the holders of KMEP Common Units are bound) of a final
partnership administrative adjustment and, if the Tax Matters Partner fails to
seek judicial review, such review may be sought by any holder having at least a
1% interest in the profits of KMEP or by holders of KMEP Common Units having in
the aggregate at least a 5% profits interest. However, only one action for
judicial review will go forward, and each holder of KMEP Common Units with an
interest in the outcome may participate.
 
    A holder of KMEP Common Units must file a statement with the IRS identifying
the treatment of any item on its federal income tax return that is not
consistent with the treatment of the item on KMEP's return to avoid the
requirement that all items be treated consistently on both returns. Intentional
or negligent disregard of the consistency requirement may subject a holder of
KMEP Common Units to substantial penalties.
 
    ELECTING LARGE PARTNERSHIPS.  The 1997 Act provides that certain
partnerships with at least 100 partners may elect to be treated as an electing
large partnership ("ELP") for tax years ending after December 31, 1997. If
further revisions are made to the law, it is possible that at some future date
KMEP will make this election to be taxed as an electing large partnership,
however, based on current law it is not contemplated that such an election will
be made for 1998 or any subsequent date.
 
    Under the reporting provisions of the 1997 Act, each partner of an ELP will
take into account separately such partner's share of several designated items,
determined at the partnership level. The ELP procedures provide that any tax
adjustments generally would flow through to the holders of KMEP Common Units for
the year in which the adjustment takes effect, and the adjustments would not
affect
 
                                      151
<PAGE>
prior-year returns of any holder, except in the case of changes to any holder's
distributive share. In lieu of passing through an adjustment to the holders of
KMEP Common Units, KMEP may elect to pay an imputed underpayment. KMEP, and not
the holders of KMEP Common Units, would be liable for any interest and penalties
resulting from a tax adjustment.
 
    NOMINEE REPORTING.  Persons who hold an interest in KMEP as a nominee for
another person are required to furnish to KMEP (a) the name, address and
taxpayer identification number of the beneficial owners and the nominee; (b)
whether the beneficial owner is (i) a person that is not a United States person,
(ii) a foreign government, an international organization or any wholly-owned
agency or instrumentality of either of the foregoing or (iii) a tax-exempt
entity; (c) the amount and description of KMEP Common Units held, acquired or
transferred for the beneficial owners; and (d) certain information including the
dates of acquisitions and transfers, means of acquisitions and transfers, and
acquisition cost for purchases, as well as the amount of net proceeds from
sales. Brokers and financial institutions are required to furnish additional
information, including whether they are a United States person and certain
information on KMEP Common Units they acquire, hold or transfer for their own
account. A penalty of $50 per failure (up to a maximum of $100,000 per calendar
year) is imposed by the Code for failure to report such information to KMEP. The
nominee is required to supply the beneficial owner of the KMEP Common Units with
the information furnished to KMEP.
 
    REGISTRATION AS A TAX SHELTER.  The Code requires that "tax shelters" be
registered with the Secretary of the Treasury. The Treasury Regulations
interpreting the tax shelter registration provisions of the Code are extremely
broad. It is arguable that KMEP is not subject to the registration requirement
on the basis that (i) it does not constitute a tax shelter, or (ii) it
constitutes a projected income investment exempt from registration. However, the
KM General Partner registered KMEP as a tax shelter with the IRS when it was
originally formed in the absence of assurance that KMEP would not be subject to
tax shelter registration and in light of the substantial penalties which might
be imposed if registration was required and not undertaken. KMEP's tax shelter
registration number with the IRS is 9228900496. This number will be provided to
every KMEP Common Unit holder with year-end tax information. ISSUANCE OF THE
REGISTRATION NUMBER DOES NOT INDICATE THAT AN INVESTMENT IN KMEP OR THE CLAIMED
TAX BENEFITS HAVE BEEN REVIEWED, EXAMINED OR APPROVED BY THE IRS. KMEP must
furnish the registration number to the holder of KMEP Common Units, and a holder
of KMEP Common Units who sells or otherwise transfers a KMEP Common Unit in a
subsequent transaction must furnish the registration number to the transferee.
The penalty for failure of the transferor of a KMEP Common Unit to furnish such
registration number to the transferee is $100 for each such failure. The holder
of KMEP Common Units must disclose the tax shelter registration number of KMEP
on Form 8271 to be attached to the tax return on which any deduction, loss,
credit or other benefit generated by KMEP is claimed or income of KMEP is
included. A holder of KMEP Common Units who fails to disclose the tax shelter
registration number on such holder's tax return, without reasonable cause for
such failure, will be subject to a $250 penalty for each such failure. Any
penalties discussed herein are not deductible for federal income tax purposes.
 
    ACCURACY--RELATED PENALTIES.  An additional tax equal to 20% of the amount
of any portion of an underpayment of tax which is attributable to one or more of
certain listed causes, including substantial understatements of income tax and
substantial valuation misstatements, is imposed by the Code. No penalty will be
imposed, however, with respect to any portion of an underpayment if it is shown
that there was a reasonable cause for such portion and that the taxpayer acted
in good faith with respect to such portion.
 
    A substantial understatement of income tax in any taxable year exists if the
amount of the understatement exceeds the greater of 10% of the tax required to
be shown on the return for the taxable year or $5,000 ($10,000 for most
corporations). The amount of any understatement subject to penalty generally is
reduced if any portion (i) is attributable to an item with respect to which
there is, or was, "substantial
 
                                      152
<PAGE>
authority" for the position taken on the return or (ii) is attributable to an
item for which there was a reasonable basis for the tax treatment of the items
and as to which the pertinent facts are disclosed on the return. Certain more
stringent rules apply to "tax shelters", which term includes a partnership if a
significant purpose of such entity is the avoidance or evasion of income tax.
This term that does not appear to include KMEP. If any partnership item of
income, gain, loss, deduction or credit included in the distributive shares of
KMEP Common Unit holders might result in such an "understatement" of income for
which no "substantial authority" exists, KMEP must disclose the pertinent facts
on its return. In addition, KMEP will make a reasonable effort to furnish
sufficient information for holders of KMEP Common Units to make adequate
disclosure on their returns to avoid liability for this penalty.
 
    A substantial valuation misstatement exists if the value of any property (or
the adjusted basis of any property) claimed on a tax return is 200% or more of
the amount determined to be the correct amount of such valuation or adjusted
basis. No penalty is imposed unless the portion of the underpayment attributable
to a substantial valuation misstatement is in excess of $5,000 ($10,000 for most
corporations). If the valuation claimed on a return is 400% or more than the
correct valuation, the penalty imposed increases to 40%.
 
OTHER TAXES
 
    Holders of KMEP Common Units may be subject to other taxes, such as state
and local taxes, unincorporated business taxes, and estate, inheritance or
intangible taxes that may be imposed by the various jurisdictions in which KMEP
does business or owns property. Santa Fe Common Unit holders should consider
state and local tax consequences of an investment in KMEP. Following the
Closing, KMEP and the Operating Partnerships will own property or conduct
business in Arizona, California, Illinois, Indiana, Iowa, Kansas, Kentucky,
Louisiana, Missouri, Nebraska, Nevada, New Mexico, Oregon, Texas and Wyoming. A
holder of KMEP Common Units will likely be required to file state income tax
returns and/or to pay such taxes in most of such states and may be subject to
penalties for failure to file tax returns and/or to pay such taxes in most of
such states and may be subject to penalties for failure to comply with such
requirements. Some of the states may require that a partnership withhold a
percentage of income from amounts that are to be distributed to a holder of KMEP
Common Units that is not a resident of the state. Such amounts withheld, if any,
which may be greater or less than a particular holder's income tax liability to
the state, generally do not relieve the non-resident Unit holder from the
obligation to file a state income tax return. Amounts withheld, if any, will be
treated as if distributed to holders of KMEP Common Units for purposes of
determining the amounts distributed by KMEP. Based on current law and its
estimate of future partnership operations, the KM General Partner anticipates
that any amounts required to be withheld will not be material. In addition, an
obligation to file tax returns or to pay taxes may arise in other states.
 
    It is the responsibility of each prospective holder of KMEP Common Units to
investigate the legal and tax consequences, under the laws of pertinent states
or localities, of such investment in KMEP. Further, it is the responsibility of
each holder of KMEP Common Units to file all state and local, as well as federal
tax returns that may be required of such holder. Morrison & Hecker has not
rendered an opinion on the state and local tax consequences of an investment in
KMEP.
 
   
    EACH HOLDER OF SANTA FE COMMON UNITS OR KMEP COMMON UNITS SHOULD CONSULT A
TAX ADVISOR AS TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER, INCLUDING THE
APPLICABILITY AND EFFECT OF ANY STATE, LOCAL, OR NON-U.S. INCOME TAX LAWS AND
ANY RECENT OR PROSPECTIVE CHANGES IN APPLICABLE TAX LAWS.

                               PURCHASE AGREEMENT
 
    This Purchase Agreement ("Agreement") is made and entered into as of the
18th day of October, 1997, by and among Kinder Morgan Energy Partners, L.P., a
Delaware master limited partnership (the "Purchaser"), Kinder Morgan G.P., Inc.,
a Delaware corporation and general partner of the Purchaser ("KM General
Partner"), Santa Fe Pacific Pipeline Partners, L.P., a Delaware master limited
partnership (the "Trading Partnership"), Santa Fe Pacific Pipelines, Inc., a
Delaware corporation and general partner of the Trading Partnership ("SF General
Partner") and SFP Pipeline Holdings, Inc., a Delaware corporation and the parent
corporation of the SF General Partner ("Holdings").
 
                              W I T N E S S E T H:
 
    WHEREAS, the Trading Partnership is the sole limited partner of SFPP, L.P.,
a Delaware limited partnership (the "Operating Partnership") of which the SF
General Partner is the sole general partner;
 
    WHEREAS, the Purchaser, directly or indirectly, desires to acquire the
interest of the Common Unit holders of the Trading Partnership in the Trading
Partnership's 98.9899% limited partnership interest in the Operating Partnership
(the "Common Unit Operating Partnership LP Interest") and the SF General
Partner's entire general partnership interest in the Trading Partnership (the
"Trading Partnership GP Interest") (together, the "Acquired Interests"); and the
Trading Partnership and the SF General Partner have agreed to sell the Acquired
Interests on the terms and subject to the conditions hereinafter set forth;
 
    NOW, THEREFORE, in consideration of the premises and the respective
representations, warranties, covenants, agreements and conditions contained
herein, the parties hereto agree as follows:
 
                                   ARTICLE I
                               PURCHASE AND SALE
 
    1.1  PURCHASE OF ACQUIRED INTERESTS.
 
    (a)  TRADING PARTNERSHIP GP INTEREST.  Prior to the Closing, as defined
below, Purchaser and KM General Partner shall form a new Delaware limited
partnership ("New LP"). At closing, New LP shall purchase the Trading
Partnership GP Interest from the SF General Partner in consideration of $90.2
million (less the amount of the Special Distribution, as defined below) in cash,
payable at the Closing by wire transfer of immediately available funds.
 
    (b)  OPERATING PARTNERSHIP LP INTEREST.  At the Closing, the Purchaser shall
purchase from the Trading Partnership the Common Unit Operating Partnership LP
Interest in consideration of a number of Common Units of Purchaser ("Purchaser
Common Units") such that, upon the liquidation of the Trading Partnership as
contemplated by Section 1.2 below, each holder of the 19,148,148 Common Units in
the Trading Partnership ("Trading Partnership Common Units") shall be
distributed a right to receive 1.39 Purchaser Common Units in respect of each
Common Unit in the Trading Partnership ("Liquidation Distribution"), and New LP
shall establish the Exchange Fund as described in Section 1.2(d). Upon
acquisition of the Common Unit Operating Partnership LP Interest, Purchaser
shall contribute such interest to New LP.
 
    1.2  LIQUIDATION OF TRADING PARTNERSHIP.
 
    (a)  AMENDMENT OF TRADING PARTNERSHIP AGREEMENT.  If necessary in,
connection with the proposed liquidation of the Trading Partnership set forth
below, the Amended and Restated Agreement of Limited Partnership of the Trading
Partnership ("Trading Partnership Agreement") shall be amended in a manner
reasonably satisfactory to the KM General Partner and SF General Partner to (i)
admit New LP as the general partner of the Trading Partnership, (ii) provide
that the distribution upon liquidation of the
 
                                      A-1
<PAGE>
Trading Partnership shall be made such that the partners of the Trading
Partnership receive the distributions set forth in Section 1.2(b) below, and
(iii) as required to implement the other transactions contemplated by this
Agreement.
 
    (b)  LIQUIDATION.  At the Closing, immediately following the completion of
the transactions described in Section 1.1, New LP (as general partner of the
Trading Partnership) shall cause the Trading Partnership to be liquidated, and
shall distribute, in accordance with the Trading Partnership Agreement, as
amended (i) to the holders of the Trading Partnership Common Units, the
Liquidation Distribution, and (ii) to New LP, the Trading Partnership's
remaining limited partnership interest in the Operating Partnership ("Remaining
Operating Partnership LP Interest") and any remaining assets of the Trading
Partnership. New LP shall cause the liquidation of the Trading Partnership and
the distribution of its assets to be effected in full compliance with all
applicable laws.
 
    (c)  FRACTIONAL UNITS.  Notwithstanding any other provision of this
Agreement (i) no certificates or scrip representing fractional Purchaser Common
Units shall be issued upon the surrender for exchange of certificates
representing Trading Partnership Common Units, and such fractional unit
interests will not entitle the owner thereof to vote or to any rights as a
limited partner of the Purchaser, and (ii) each holder of Trading Partnership
Common Units exchanged pursuant to the liquidation of the Trading Partnership
who would otherwise have been entitled to receive a fractional Purchaser Common
Unit (after taking into account all Purchaser Common Units held by such holder
at the Closing Date) shall receive, in lieu thereof, from Purchaser in exchange
for such fractional unit upon delivery of the Certificates to the Exchange Agent
(each as defined below), an amount in cash ("Fractional Unit Payment") (payable
in dollars, without interest) equal to the product obtained by multiplying (A)
the fractional unit interest to which such holder (after taking into account all
Purchaser Common Units held by such holder at the Closing Date) would otherwise
be entitled by (B) the average of the high and low trading prices of Purchaser
Common Units on the New York Stock Exchange on the last trading day prior to the
Closing Date.
 
    (d)  EXCHANGE AGENT.  Prior to the mailing of the Joint Proxy
Statement/Prospectus, as defined below, Purchaser shall cause New LP to appoint
First Chicago Trust Company of New York to act as exchange agent (the "Exchange
Agent") for the payment of the Liquidation Distribution and any Fractional Unit
Payment. At or prior to the Closing Date, Purchaser shall cause New LP to
deposit with the Exchange Agent, for the benefit of the holders of the Trading
Partnership Common Units, the estimated aggregate Fractional Unit Payment (the
"Exchange Fund") and Purchaser will authorize the Exchange Agent to issue
Purchaser Common Units constituting the Liquidation Distribution, for exchange
in accordance with this Section 1.2. Purchaser shall cause New LP to deposit
with the Exchange Agent any additional funds in excess of the Exchange Fund as
and when necessary to pay any Fractional Unit Payment required to be paid under
this Agreement. Purchaser shall cause New LP to pay all costs and fees of the
Exchange Agent and for all expenses associated with the Liquidation Distribution
and the exchange process. Any Purchaser Common Units, or fraction thereof, and
any remaining amount of the Exchange Fund or other funds deposited, after the
earlier to occur of (i) payment in full of all amounts due to the holders of the
Certificates or to the Exchange Agent or (ii) the expiration of the period
specified in Section 1.2(h) below, shall be returned to Purchaser or New LP, as
applicable.
 
    (e)  EXCHANGE PROCEDURES.  Promptly after the Closing Date, Purchaser shall
cause New LP to cause the Exchange Agent to mail to each record holder, as of
the Closing Date, of an outstanding certificate or certificates that immediately
prior to the Closing Date represented Trading Partnership Common Units (the
"Certificates"), a form of letter of transmittal (the "Letter of Transmittal")
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon proper delivery of the Certificates to
the Exchange Agent and which shall be in such form and have such other
provisions as New LP and the SF General Partner may reasonably specify) and
instructions for use in effecting the surrender of the Certificate(s) and
payment therefor. Upon surrender to the Exchange Agent of such Certificates,
together with such properly completed and duly executed Letter of Transmittal,
the holder of
 
                                      A-2
<PAGE>
a Certificate shall be entitled to a certificate or certificates representing
the number of full Purchaser Common Units into which the Certificates
surrendered shall have been converted pursuant to this Agreement and the
Fractional Unit Payment, if any, payable in redemption of any fractional
Purchaser Common Unit otherwise issuable. The instructions for effecting the
surrender of Certificates shall set forth procedures that must be taken by the
holder of any Certificate that has been lost, destroyed or stolen. It shall be a
condition to the right of such holder to receive a certificate representing
Purchaser Common Units and the Fractional Unit Payment, if any, that the
Exchange Agent shall have received, along with the Letter of Transmittal, a duly
executed lost certificate affidavit, including an agreement to indemnify
Purchaser and New LP, signed exactly as the name or names of the registered
holder or holders appeared on the books of the Trading Partnership immediately
prior to the Effective Time, together with a customary bond and such other
documents as Purchaser or New LP may reasonably require in connection therewith.
After the Closing Date, there shall be no further transfer on the records of the
Trading Partnership or its transfer agent of certificates representing Trading
Partnership Common Units and if such certificates are presented to the Trading
Partnership for transfer, they shall be canceled against delivery of the
certificate or certificates for Purchaser Common Units and Fractional Unit
Payment as hereinabove provided. If any certificate for such Purchaser Common
Units is to be issued to a person or entity other than the registered holder of
a Certificate surrendered for exchange, it shall be a condition of such exchange
that the Certificate so surrendered shall be properly endorsed, with signature
guaranteed, or otherwise in proper form for transfer and that the person
requesting such exchange shall pay to New LP or the Exchange Agent any transfer
or other taxes required by reason of the issuance of certificates for such
Purchaser Common Units in a name other than that of the registered holder of the
Certificate(s) surrendered, or establish to the reasonable satisfaction of New
LP or the Exchange Agent that such tax has been paid or is not applicable. Until
surrendered as contemplated by this Section 1.2(e), each Certificate shall be
deemed at any time after the Closing Date to represent only the right to receive
upon such surrender the Liquidation Distribution and Fractional Unit Payment, if
any, as contemplated by Section 1.2. No interest will be paid or will accrue on
any Fractional Unit Payment.
 
    (f)  DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED UNITS.  No dividends or other
distributions with respect to Purchaser Common Units with a record date after
the Closing Date shall be paid to the holder of any unsurrendered Certificate
with respect to the Purchaser Common Units issuable in respect thereof and no
Fractional Unit Payment shall be paid to any such holder until the surrender of
such Certificate in accordance with this Section 1.2. Subject to the effect of
applicable laws, there shall be paid to the holder of the Certificate, without
interest, (i) at the time of surrender of any such Certificate, the amount of
any Fractional Unit Payment to which such holder is entitled and the amount of
dividends or other distributions previously paid with respect to such whole
Purchaser Common Units with a record date after the Closing Date and (ii) at the
appropriate payment date, the amount of dividends or other distributions payable
with respect to such whole Purchaser Common Units with a record date after the
Closing Date and prior to such surrender and a payment date subsequent to such
surrender.
 
    (g)  NO FURTHER OWNERSHIP RIGHTS IN TRADING PARTNERSHIP COMMON UNITS.  All
Purchaser Common Units issued upon the surrender for exchange of Certificates in
accordance with the terms of this Section 1.2 (including any Fractional Unit
Payment) shall be deemed to have been issued (and paid) in full satisfaction of
all rights pertaining to the Trading Partnership Common Units heretofore
represented by such Certificates, subject, however, to the Purchaser's
obligation, with respect to Trading Partnership Common Units outstanding
immediately prior to the Closing Date, to pay any dividends or make any other
distributions with a record date prior to the Closing Date which may have been
declared or made by the Trading Partnership on such Trading Partnership Common
Units in accordance with the terms of this Agreement on or prior to the Closing
Date and which remain unpaid at the Closing Date.
 
    (h)  TERMINATION OF EXCHANGE FUND.  Any portion of the Exchange Fund which
remains undistributed to the holders of the Certificates for twelve months after
the Closing Date shall be delivered to Purchaser, upon demand, and any holders
of Trading Partnership Common Units who have not theretofore complied
 
                                      A-3
<PAGE>
with this Section 1.2 shall thereafter look only to Purchaser and only as
general creditors thereof for payment of their claim for Purchaser Common Units,
any Fractional Unit Payment and any dividends or distributions with respect to
Purchaser Common Units to which such holders may be entitled.
 
    (i)  NO LIABILITY.  None of Purchaser, New LP, the Trading Partnership or
the Exchange Agent shall be liable to any person in respect of any Purchaser
Common Units (or dividends or distributions with respect thereto) or Fractional
Unit Payment delivered to a public official pursuant to any applicable abandoned
property, escheat or similar law. If any Certificates shall not have been
surrendered prior to such date on which any Purchaser Common Units, any
Fractional Unit Payment or any dividends or distributions with respect to
Purchaser Common Units in respect of such Certificate would escheat to or become
the property of any governmental entity or authority, any such shares, cash,
dividends or distributions in respect of such Certificates shall, to the extent
permitted by applicable law, become the property of New LP, free and clear of
all claims or interest of any person or entity previously entitled thereto other
than the holder of such Certificate as specified in Section 1.2(h).
 
    1.3  TRANSACTIONS INVOLVING OPERATING PARTNERSHIP.
 
    (a)  AMENDMENT OF AGREEMENT.  At the Closing Date, immediately following the
completion of the transactions described in Sections 1.1, 1.2(a) and 1.2(b),
Purchaser (through New LP) and the SF General Partner will cause the Agreement
of Limited Partnership of the Operating Partnership to be amended and restated
in such form as the KM General Partner and the SF General Partner shall
reasonably agree prior to the date of the Joint Proxy Statement/Prospectus (the
"Amended and Restated Operating Partnership Agreement") (i) to provide for a
98.9899% general partnership interest for which the prior limited partnership
interest owned by New LP pursuant to the operation of Sections 1.1 and 1.2 shall
be exchanged, (ii) to provide for a 1.0101% special limited partnership interest
for which the prior general partnership interest of the SF General Partner shall
be exchanged, and (iii) to provide that New LP, as general partner of the
Operating Partnership, and the KM General Partner, as general partner of New LP,
shall be subrogated to the rights of any holder of Indemnified Debt, as defined
below, to the extent that New LP, as general partner of the Operating
Partnership, and the KM General Partner, as general partner of New LP, have made
any payment in respect of such Indemnified Debt. Upon the execution of the
Amended and Restated Operating Partnership Agreement, New LP and the SF General
Partner shall exchange their prior interests in the Operating Partnership for
those interests described above. The special limited partnership interest to be
obtained by the SF General Partner shall be nontransferable (except to an
affiliate (as defined below) of the SF General Partner) other than as described
below and shall have no voting rights except with respect to mergers,
consolidations or dissolution and liquidation. As used herein, the term
"affiliate" shall have the meaning assigned to such term in Rule 12b-2 under the
Securities Exchange Act of 1934, as amended. Any cash contributed to New LP
shall not be contributed, directly or indirectly, to the Operating Partnership.
 
    (b)  SPECIAL DISTRIBUTION.  Immediately following the transactions described
in Section 1.3(a), New LP shall cause the Operating Partnership to redeem that
portion of the SF General Partner's special limited partnership interest in the
Operating Partnership equal to a 0.5101% interest in the Operating Partnership,
in consideration of the amount of $5.8 million (which the parties agree
represents the fair market value of a 0.5101% interest in the Operating
Partnership) by wire transfer of immediately available funds (the "Special
Distribution"). Upon payment of the Special Distribution and the redemption of
such interest, the special limited partnership interest of the SF General
Partner in the Operating Partnership shall be reduced to 0.50% (the "Special
Limited Partnership Interest"), and the general partnership interest of New LP
in the Operating Partnership shall be increased to 99.50%. The Special
Distribution shall be paid solely from funds of the Operating Partnership, and
shall not be paid, directly or indirectly (including by way of post-payment
reimbursement) by Purchaser or its affiliates.
 
    (c)  PUT RIGHT.  At any time on or after January 1, 1999, the SF General
Partner may require, upon 30 days prior written notice to the KM General Partner
and the Operating Partnership (the "Put Notice"),
 
                                      A-4
<PAGE>
that the Operating Partnership purchase all (but not less than all) of the
Special Limited Partnership Interest. The Operating Partnership may elect to
have an affiliate make such purchase. The purchase price shall consist of (i)
cash in an amount equal to the fair market value on the date of the Put Notice
of a number of Purchaser Common Units equal to $4.5 million divided by the
average closing price of the Purchaser Common Units on the New York Stock
Exchange for the date of this Agreement, the three trading days immediately
prior to such date and the three trading days immediately after such date;
provided, that the Operating Partnership may, in its sole discretion, elect to
deliver such number of Purchaser Common Units ("Put/Call Units") in lieu of
making such cash payment. The KM General Partner shall notify the SF General
Partner within ten business days of the Put Notice if the Operating Partnership
or an affiliate thereof chooses to deliver the Put/Call Units and if no such
notification is made, the Operating Partnership or an affiliate thereof shall be
required to pay, and Purchaser will cause the Operating Partnership or an
affiliate thereof to pay, the cash amount described in this Section 1.3(c). Any
payment pursuant to this paragraph shall be made by wire transfer of immediately
available funds or by delivery of fully paid and non-assessable Put/Call Units
no later than 30 days after the date of such Put Notice.
 
    (d)  CALL RIGHT.  At any time New LP may require, upon 30 days prior written
notice to the SF General Partner (the "Call Notice"), that the SF General
Partner sell to the Operating Partnership or an affiliate thereof all (but not
less than all) of the Special Limited Partnership Interest in consideration of
(i) the payment of the cash price or issuance of the Put/Call Units as provided
in Section 1.3(c), and (ii) an additional amount in cash sufficient to result in
the SF General Partner receiving on an after-tax basis (using the rates and
methodology described in clause (B) below) under this clause (ii) an additional
amount in cash equal to (A) any incremental gain realized by the SF General
Partner resulting from a decrease in its share of partnership debt, multiplied
by (B) the maximum net marginal statutory federal and state income tax rates
applicable to the SF General Partner (taking into account the deductibility of
state income tax in determining the liability for federal income tax). Such
purchase shall be effected no later than 30 days after the date of the Call
Notice. New LP shall notify the SF General Partner in the Call Notice if the
Put/Call Units shall be delivered in lieu of the cash payment under clause (i)
hereof and if no such notification is made, the Operating Partnership or an
affiliate thereof shall be required to pay the cash amount described in clauses
(i) and (ii) in this Section 1.3(d).
 
    (e)  REGISTRATION.  Purchaser and the KM General Partner shall cause all
Put/Call Units to be duly authorized and issued, and, as promptly as
practicable, but in no event more than 90 days after the issuance thereof, the
KM General Partner and Purchaser shall (i) cause the resale of the Put/Call
Units by the SF General Partner to be registered under the Securities Act of
1933, as amended ("Securities Act") and any applicable state securities laws and
cause the Put/Call Units to be approved for issuance on the New York Stock
Exchange, (ii) deliver to the SF General Partner an opinion of securities law
counsel, which counsel shall be reasonably satisfactory to the SF General
Partner, to the effect that such registration is not necessary to allow the SF
General Partner to freely transfer the Put/Call Units under applicable law or
(iii) cause the Operating Partnership or an affiliate thereof to pay the cash
amount determined above in immediately available funds in lieu of such Put/Call
Units. The KM General Partner and Purchaser shall cause such registration to
remain effective until the earlier of (i) such time as the SF General Partner
shall have disposed of all of the Put/Call Units held by it or (ii) twelve
months after the effective date thereof.
 
    1.4  CERTAIN AGREEMENTS WITH RESPECT TO VREDS.
 
    (a)  ASSIGNMENT OF COMMON UNITS.  At the Closing, the SF General Partner
shall place the Trading Partnership Common Units for which Holdings' Variable
Rate Exchangeable Debentures Due 2010 (the "VREDs") are exchangeable and the
right to receive any Purchaser Common Units distributed by the Trading
Partnership with respect thereto in escrow with a third-party escrow agent
agreed to by the parties hereto. Such units shall be released in accordance with
the terms of an escrow agreement (in form and substance reasonably acceptable to
Purchaser and the SF General Partner to be entered into prior to the date of the
Joint Proxy Statement/Prospectus) (the "Escrow Agreement") upon satisfaction and
discharge
 
                                      A-5
<PAGE>
of the VREDs or as part of the satisfaction and discharge of the VREDs. During
the term of the Escrow Agreement, the SF General Partner shall be the owner of
the Purchaser Common Units for all purposes including without limitation for tax
and allocation purposes, and Holdings shall continue to be the principal obligor
on the VREDs.
 
    (b)  NEGOTIATIONS WITH VREDS AND ASSUMPTION OF OBLIGATIONS.  Prior to the
Closing Date, the Purchaser shall use its reasonable best efforts to negotiate
agreements with the holders of the VREDs such that, at the Closing, all of the
VREDs will be satisfied and discharged (by the payment of cash, the delivery of
securities of Purchaser, exchange for Trading Partnership Common Units or
Purchaser Common Units, or otherwise) at no cost or expense to the SF General
Partner, Holdings or any of their affiliates except as otherwise provided in the
next sentence. From and after the Closing, New LP shall pay and perform, as and
when due and for the account of Holdings, all obligations of Holdings under or
with respect to the VREDs; provided, however, that any taxable gain related to
the satisfaction and discharge of the VREDs shall be for the account of the SF
General Partner or Holdings, as applicable. In addition, New LP shall have the
right to make all elections or decisions pursuant to the terms of the VREDs or
the indenture and the agreements related thereto. At Closing, Holdings shall
enter into a supplemental indenture with respect to the VREDs, in form and
substance satisfactory to New LP, to provide for the substitution of the
Purchaser Common Units for the Trading Partnership Common Units subject to the
VREDs that remain outstanding.
 
    (c)  BENEFIT OF NEGOTIATIONS.  To the extent the Purchaser negotiates an
agreement with the holders of the VREDs that results in a reduction in any
amount that otherwise would have been payable to such holders, such benefit
shall be for the account of Purchaser and its affiliates and not for the SF
General Partner or its affiliates; provided, however, that no adjustment shall
be made to any consideration specifically to be paid to the SF General Partner
or the Trading Partnership pursuant to the terms of this Agreement except for
any adjustment to the number of Purchaser Common Units after those units have
been placed in escrow in accordance herewith due to any agreement between the
Purchaser and the holders of the VREDs.

    The Trading Partnership, the SF General Partner and Holdings (the "SF

Partnership is duly organized, validly existing and in good standing under the
laws of the State of Delaware. Each of the SF Parties and the Operating
Partnership has full power and authority to own and hold the properties and
assets it now owns and holds and to carry on its businesses as and where such
properties are now owned or held and such business is now conducted. Each of the
SF Parties and the Operating Partnership are duly licensed or qualified to do
business as a foreign corporation or limited partnership, as applicable, and are
in good standing in each jurisdiction in which the character of the properties

by them requires them to be so licensed or qualified and where the failure so to
qualify might reasonably be expected to have a Material Adverse Effect, as
defined below. Schedule 3.1 contains a list of each jurisdiction in which the
Trading Partnership, the Operating Partnership or the SF General Partner are
duly licensed or qualified to do business as a foreign limited partnership or
corporation. Except as set forth on Schedule 3.1, the Trading Partnership and
the Operating Partnership have no direct or indirect investment or interest in
or control over any other corporation, partnership, joint venture or other
business entity.

Securities Act) complied in all material respects with the applicable
requirements of the Securities Act and the Exchange Act, (c) no such filing, at
the time described above, contained any untrue statement of a material fact or

limited partnership interests in the Trading Partnership other than the SF
General Partner and its affiliates (a "Superior Transaction") and (c) the

Indemnified Debt, or (e) take or fail to take any other action (other than the
payment of the Indemnified Debt as originally scheduled) that would result in
the share of the Indemnified Debt which is allocated to the SF General Partner
for purposes of Section 752 of the Internal Revenue Code of 1986 and Treasury
Regulations promulgated thereunder (the "Code") pursuant to the Debt Indemnity
to be reduced below $190 million; provided, however, that the Operating
Partnership shall not be required to do any of the foregoing with respect to an
amount in excess of $190 million and such covenants shall not apply to any
indebtedness of Purchaser or any of its other affiliates. Following the Closing

termination of the Debt Indemnity pursuant to Section 9.3 (i) the Operating
Partnership shall use its reasonable best efforts to not take or omit to take
any action, if such action or omission (with the giving of notice or the passing
of time, or both) would constitute a breach of, or give rise to a default or
event of default under, any Indemnified Debt, and (ii) the SF General Partner
shall have the right, but not the obligation, to arrange for the refinancing
described above if and only if the Operating Partnership is unable to do so in
accordance with this paragraph. From and after the Closing and until the
termination of the Debt Indemnity pursuant to Section 9.3, the Operating
Partnership shall furnish to the SF General Partner, (A) within 30 days after
the end of each fiscal quarter, a certificate of
 
                                      A-17
<PAGE>
the chief financial officer of Purchaser, stating that (1) at least $190 million
of Indemnified Debt is outstanding, and (2) no event that constitutes, or with
the passing of time or the giving of notice, or both, would reasonably be
expected to constitute, an event of default under any Indemnified Debt has
occurred, or if any such event has occurred, describing such event and the
action the Purchaser intends to take with respect thereto, (B) concurrently with
providing them to the lenders, agents or trustees in respect of the Indemnified
Debt, copies of any compliance certificates, together with any attachments
thereto, required pursuant to any Indemnified Debt, (C) promptly upon obtaining
knowledge thereof, a description, in reasonable detail, of any event that
constitutes, or with the passing of time or the giving of notice, or both, would
reasonably be expected to constitute, an event of default under the Indemnified
Debt and (D) such other documents or information as the SF General Partner may
reasonably request relating specifically and primarily to the Indemnified Debt

applicable tax returns consistent with the allocation of the Indemnified Debt to

reference to the change in ownership for the purpose of effecting the transfer
or issuance of the permits required under environmental laws for the operation
and the conduct of the business of the Operating Partnership ("Environmental
Permits"), (b) effectuating the issuance or transfer, as promptly as is
reasonably possible on or after the Closing Date, of all Environmental Permits
and any other licenses or permits ("Other Permits") required as of the Closing
Date, and (c) identifying, preparing and filing any notices or reports required
from the KM General Partner in connection with the transfer or issuance of the
required Environmental Permits and Other Permits. For the interim period from
the Closing Date until such time as the required Environmental Permits and the
Other Permits in form and substance reasonably satisfactory to the KM General
Partner shall be transferred to or issued, and to the extent permitted by law,
the SF General Partner, on behalf of the Operating Partnership, authorizes the
Operating Partnership after acquisition by the KM Parties to operate under and
utilize the Operating Partnership's existing Environmental Permits and Other
Permits.
 
    5.13  FURTHER ACTION; REASONABLE BEST EFFORTS.  From the date hereof through
the Closing Date, upon the terms and subject to the conditions hereof, each of
the parties hereto shall use its reasonable best efforts to take, or cause to be
taken, all appropriate action, and to do or cause to be done, all things
necessary, proper or advisable under applicable laws and regulations to
consummate and make effective the transactions contemplated by this Agreement,
including but not limited to (i) cooperating in the preparation and filing of
the Joint Proxy Statement/Prospectus and Registration Statement, and any
amendments to any thereof, (ii) using its reasonable best efforts to obtain all
Required Consents and (iii) using its reasonable best efforts to make all
required regulatory filings and applications and to obtain all licenses,
permits, consents, approvals, authorizations, qualifications and orders of
governmental entities or authorities and parties to contracts as are necessary
for the consummation of the transaction contemplated by this Agreement and to
fulfill the conditions to the consummation of this Agreement; provided that the
KM General Partner shall be primarily responsible for obtaining or transferring
all required licenses, permits and authorizations, and the SF General Partner
shall cooperate in such process as reasonably requested by the KM General
Partner. To the extent practicable in the circumstances and subject to
applicable laws, each party shall provide the other with the opportunity to
review all information relating to the other party, or any of its subsidiaries,
which appears in any filing made with, or written materials submitted to, any
governmental entity or authority in connection with obtaining the necessary
regulatory approvals for the consummation of the transactions contemplated by
this Agreement. In case at any time after the Closing Date any further action is
necessary or desirable to carry out the purposes of this Agreement, the proper
officers and directors of each part to this Agreement shall use their reasonable
best efforts to take all such necessary action.

    (l)  PURCHASER AVERAGE PRICE.  By the SF General Partner, the Special
Committee or the KM General Partner if the Purchaser Average Price is less than
$31.32 or greater than $46.98 on any day after the date of this Agreement up to

    8.2  EFFECT OF TERMINATION.  The following provisions shall apply in the
event of a termination of this Agreement:
 
    (a)  NO LIABILITY.  If this Agreement is terminated as permitted under
Section 8.1 (other than as permitted under Section 8.1(i)), no party hereto (or
its officers or directors) will have any liability or further obligation to any
other party to this Agreement, except for obligations pursuant to the last
sentence of Section 5.1 hereof and any liability resulting from the breach
hereof.
 
    (b)  EXPENSE REIMBURSEMENT.  If this Agreement is terminated as permitted
under Section 8.1(i), or, during the pendency of a Superior Transaction, as
permitted under Section 8.1(j), then the SF General Partner shall have the
obligation to pay or cause to be paid to Purchaser its actual third party
expenses arising out of the transactions contemplated hereby up to a maximum of
$2.5 million, and upon receipt of such amount the KM Parties shall have no
further recourse or claim against any party hereto. No obligations of the SF
General Partner, the Trading Partnership or the Operating Partnership under this
Agreement shall be terminated until such payment has been made.
 
    (c)  SPECIFIC PERFORMANCE.  The parties hereto acknowledge that the
transactions contemplated hereby are unique and specifically identifiable.
Accordingly, the parties hereto further agree and stipulate that if the Closing
does not occur because of the willful failure of the SF Parties, on the one
hand, or the KM Parties, on the other hand, to perform their respective
obligations hereunder, (i) monetary damages and any other remedy at law will not
be adequate, (ii) the non-defaulting party shall be entitled to specific
performance as the remedy for such breach, (iii) each party hereto agrees to
waive any objection to the remedy of specific performance, (iv) each party
agrees that the granting of specific performance by any court will not be deemed
to be harsh or oppressive to the party who is ordered specifically to perform
its obligations under this Agreement, and (v) in connection with any action for
specific performance, the prevailing party shall be entitled to reasonable
attorneys' fees and other costs of prosecuting or defending such action.
 
    (d)  OTHER REMEDIES.  The right to seek specific performance hereunder shall
not preclude any party to seek any other remedy at law or in equity.
 
                                   ARTICLE IX
                                INDEMNIFICATION
 
    9.1  INDEMNIFICATION OF CERTAIN SF PARTIES.  The Purchaser, from and after
the Closing, shall (and shall cause the Operating Partnership to) indemnify and
hold harmless the SF General Partner, Holdings and their respective
stockholders, officers, directors, affiliates, successors and assigns from and
against any and all losses, costs, damages, expenses, liabilities and claims
(collectively, "Losses") arising or resulting from, or relating to (a) the
Trading Partnership or the Operating Partnership (whether prior to or after the
Closing) (including, without limitation, the Sparks, Nevada environmental
matters and any obligations pursuant to that certain Promissory Note made
October 6, 1997 in the amount of $8 million and payable to Andrew B. Krafsur, in
his capacity as Chapter 7 Trustee for the Bankruptcy Estate of El Paso Refinery,
L.P. and the settlement agreement to which such note relates, (b) the VREDs,
except as set forth in Section 1.4, (c) the severance costs referred to in
Article VII in excess of the $4.5 million referred to in Section 7.1 or any
action taken by Purchaser or the KM General Partner in connection therewith, and
(d) the amounts referred to in Section 5.19(a)(ii), except in each case for
Losses for which the SF General Partner is
 
                                      A-27
<PAGE>
indemnifying the Purchaser and it affiliates pursuant to Section 9.2 below.
Without limiting the generality of the foregoing, from and after the Closing the
Purchaser shall indemnify and hold harmless the SF General Partner, Holdings and
their respective stockholders, officers, directors, affiliates, successors and
assigns (including any person who has acted in any such capacity at any time
prior to Closing), in the manner set forth in Section 6.7 of the Trading
Partnership Agreement, from and against all Losses from which such persons, or
any of them, would have been entitled to be indemnified pursuant to Section 6.7
of the Trading Partnership Agreement except in each case for Losses for which
the SF General Partner is indemnifying the Purchaser and its affiliates pursuant
to Section 9.2 below.
 
    9.2  INDEMNIFICATION OF THE KM PARTIES.
 
    (a)  DEBT INDEMNITY.  The SF General Partner, from and after the Closing
Date, shall indemnify and hold harmless the KM General Partner and New LP from
and against any and all Losses arising or resulting from, or relating to any
payments that New LP, as the general partner of the Operating Partnership, or
the KM General Partner, as general partner of New LP, is required to make (and
makes) from its own funds (after prior recourse is had to the assets of the
Operating Partnership) with respect to the First Mortgage Notes and any
refinancing, refunding or replacement thereof ("Indemnified Debt"), due to the
inability of the Operating Partnership to pay or refinance any such Indemnified
Debt from the assets of the Operating Partnership. The indemnity described in
this Section 9.2(a) ("Debt Indemnity") shall be limited to the amount of $190
million. The SF General Partner shall be subrogated to such rights of New LP to
the extent that the SF General Partner has made any payment in respect of the
Debt Indemnity.
 
    (b)  SPECIAL INDEMNITY.  The SF General Partner, from and after the Closing
Date, shall indemnify and hold harmless the KM General Partner, Purchaser, New
LP and their respective stockholders, unit holders, officers, directors,
affiliates, successors and assigns from and against any and all Losses arising
or resulting from, or relating to any claim for money damages by any limited
partner of the Trading Partnership (other than Purchaser and its affiliates)
relating to the fairness of the transactions contemplated by this Agreement to
such limited partners; provided, however, that any liability for fees and
expenses of attorneys for any such limited partner of the Trading Partnership
shall be borne in equal halves by the SF General Partner, on the one hand, and
the KM General Partner, Purchaser and New LP, on the other hand.
 
    (c)  OTHER INDEMNITY.  The SF General Partner, from and after the Closing
Date, shall indemnify and hold harmless the KM General Partner, Purchaser, New
LP, and their respective stockholders, unit holders, officers, directors,
affiliates, successors and assigns from and against any and all Losses arising
or resulting from, or relating to ("Other Indemnity") (i) any material breach of
the representation or warranty in Section 3.6 hereof, (ii) any taxes assessed
against the Purchaser or KM General Partner due to the liquidation of the
Trading Partnership pursuant to the terms of this Agreement, (iii) any claim by
any holder of the VREDs or the First Mortgage Notes, or by any lender under the
Credit Agreement (other than by Purchaser and its affiliates) with respect to
the VREDs, the First Mortgage Notes or the Credit Agreement, to the extent
relating to any act or omission of the SF General Partner, Holdings or their
affiliates prior to Closing, if such claim has been asserted in writing prior to
the Closing and does not arise from or relate to the transactions contemplated
by this Agreement or any action or omission otherwise requested by Purchaser,
(iv) the fees and expenses referred to in Section 5.19(b), (v) any of the other
liabilities or obligations set forth in Section 7.5 hereof or (vi) matters which
are excluded from the reimbursement obligations provided for in Section
5.19(a)(ii).
 
    9.3  TERMINATION.  All obligations of the SF General Partner (other than
obligations with respect to payments that may become due as a result of any
claims made by any holder of Indemnified Debt prior to date of termination) with
respect to the Debt Indemnity shall terminate upon the delivery of a Put Notice
or a sale pursuant to the exercise of the call rights described in Section 1.3
by the SF General Partner with
 
                                      A-28
<PAGE>
respect to the Special Limited Partnership Interest. In addition, all
obligations of the SF General Partner with respect to the Other Indemnity shall
terminate on the second anniversary of the Closing.
 
    9.4  DEMANDS.  Each indemnified party hereunder agrees that promptly upon
its discovery of facts giving rise to a claim for indemnity under the provisions
of this Agreement, including receipt by it of notice of any demand, assertion,
claim, action or proceeding, judicial or otherwise, by any third party (such
third party actions being collectively referred to herein as the "Claim"), with
respect to any matter as to which it claims to be entitled to indemnity under
the provisions of this Agreement, it will give prompt notice thereof in writing
to the indemnifying party, together with a statement of such information
respecting any of the foregoing as it shall have. Such notice shall include a
demand for indemnification under this Agreement. The indemnifying party shall
not be obligated to indemnify the indemnified party with respect to any Claim if
the indemnified party knowingly failed to notify the indemnifying party thereof
in accordance with the provisions of this Agreement in sufficient time to permit
the indemnifying party or its counsel to defend against such matter and to make
a timely response thereto including, without limitation, any responsive motion
or answer to a complaint, petition, notice or other legal, equitable or
administrative process relating to the Claim, only insofar as such knowing
failure to notify the indemnifying party has actually resulted in prejudice or
damage to the indemnifying party.
 
    9.5  RIGHT TO CONTEST AND DEFEND.  The indemnifying party shall be entitled
at its cost and expense to contest and defend by all appropriate legal
proceedings any Claim with respect to which it is called upon to indemnify the
indemnified party under the provisions of this Agreement; provided, that notice
of the intention so to contest shall be delivered by the indemnifying party to
the indemnified party within 20 days from the date of receipt by the
indemnifying party of notice by the indemnified party of the assertion of the
Claim. Any such contest may be conducted in the name and on behalf of the
indemnifying party or the indemnified party as may be appropriate. Such contest
shall be conducted by counsel selected and employed by the indemnifying party
and reasonably acceptable to the indemnified party, but the indemnified party
shall have the right but not the obligation to participate in such proceedings
and to be represented by counsel of its own choosing at its sole cost and
expense. Provided that the indemnifying party acknowledges in writing that it is
unconditionally obligated to provide such indemnification, the indemnifying
party shall have full authority to determine all action to be taken with respect
thereto; provided, however, that the indemnifying party will not have the
authority to subject the indemnified party to any obligation whatsoever, other
than the performance of purely ministerial tasks or obligations not involving
material expense. If the indemnifying party does not elect to contest any such
Claim, the indemnifying party shall be bound by the result obtained with respect
thereto by the indemnified party. At any time after the commencement of the
defense of any Claim, the indemnifying party may request the indemnified party
to agree in writing to the abandonment of such contest or to the payment or
compromise by the indemnifying party of the asserted Claim, whereupon such
action shall be taken unless the indemnified party determines that the contest
should be continued, and so notifies the indemnifying party in writing within 15
days of such request from the indemnifying party. If such abandonment or
compromise contemplates (i) the unconditional release of the indemnified party
from all further Claims arising out of the subject matter thereof, (ii) no
admission of culpability by the indemnified party and (iii) no restrictions on
the future operations of the indemnified party, and the indemnified party
nevertheless determines that the contest should be continued, the indemnifying
party shall be liable hereunder only to the extent of the amount that the other
party to the contested Claim had agreed unconditionally to accept in payment or
compromise as of the time the indemnifying party made its request therefor to
the indemnified party.
 
    9.6  COOPERATION.  If requested by the indemnifying party, the indemnified
party agrees to cooperate with the indemnifying party and its counsel at the
cost of the indemnifying party in contesting any Claim that the indemnifying
party elects to contest or, if appropriate, in making any counterclaim against
the person asserting the Claim, or any cross-complaint against any person, and
the indemnifying party will reimburse the indemnified party for any expenses
incurred by it in so cooperating. At no cost or expense to
 
                                      A-29
<PAGE>
the indemnified party, the indemnifying party shall cooperate with the
indemnified party and its counsel in contesting any Claim.
 
    9.7  RIGHT TO PARTICIPATE.  The indemnified party and the indemnifying party
each agree to afford the other party and its counsel the opportunity to be
present at, and to participate in, conferences with all persons, including
governmental authorities, asserting any Claim against the indemnified party or
conferences with representatives of or counsel for such persons.
 
    9.8  PAYMENT OF DAMAGES.  The indemnifying party shall pay to the
indemnified party in immediately available funds any amounts to which the
indemnified party may become entitled by reason of the provisions of this
Agreement, such payment to be made within five days after any such amounts are
finally determined either by mutual agreement of the parties hereto or pursuant
to the final unappealable judgment of a court of competent jurisdiction. In
calculating any amount to be paid by an indemnifying party by reason of the
provisions of this Agreement, the amount shall be reduced by the amount of all
tax benefits and other reimbursements credited to or received by the other party
related to the applicable Losses and shall be increased by the amount of all tax
liabilities and other disbursements to be paid or incurred by the other party
related to the receipt of funds pursuant to the indemnity.

                                 MISCELLANEOUS
 
    10.1  NONSURVIVAL OF REPRESENTATIONS AND WARRANTIES.  None of the
representations and warranties in this Agreement shall survive the Closing
except for the representations and warranties contained in Section 3.6 by the SF
General Partner, which shall survive, as to the SF General Partner, for a period
of 2 years following the Closing Date. All covenants, agreements and indemnities
contained herein which, by their terms, are to be performed after the Closing
shall survive the Closing.

                            Form of Affiliate Letter
                                     [Date]
 
Kinder Morgan Energy Partners, L.P.
1301 McKinney Street, Suite 3450
Houston, Texas 77010
 
Ladies and Gentlemen:
 
    The undersigned, a holder of limited partnership common units ("Common
Units") of Santa Fe Pacific Pipeline Partners, L.P., a Delaware master limited
partnership, in connection with certain transactions (the "Transactions") may be
entitled to receive limited partnership common units ("KM Units") of Kinder
Morgan Energy Partners, L.P. (the "Partnership"). The undersigned acknowledges
that the undersigned may be deemed an "affiliate" of the Partnership within the
meaning of Rule 145 ("Rule 145") promulgated under the Securities Act of 1933,
as amended (the "Act"), although nothing contained herein should be construed as
an admission of such fact.
 
    If in fact the undersigned were an affiliate under the Act, the
undersigned's ability to sell, assign or transfer any KM Units received by the
undersigned in exchange for any Common Units pursuant to the Transactions may be
restricted unless such transaction is registered under the Act or an exemption
from such registration is available. The undersigned understands that such
exemptions are limited and the undersigned has obtained advice of counsel as to
the nature and conditions of such exemptions, including information with respect
to applicability to the sale of such securities of Rules 144 and 145(d)
promulgated under the Act.
 
    The undersigned hereby represents to and covenants with the Partnership that
the undersigned will not sell, assign or transfer any of the KM Units that the
undersigned receives in exchange for Common Units pursuant to the Transactions
except (i) pursuant to an effective registration statement under the Act, (ii)
in conformity with the volume and other limitations of Rule 145, or (iii) in a
transaction which, in the opinion of independent counsel reasonably satisfactory
to the Partnership or as described in a "no-action" or interpretive letter from
the Staff of the Securities and Exchange Commission (the "SEC"), is not required
to be registered under the Act.
 
    In the event of a sale or other disposition by the undersigned of KM Units
pursuant to Rule 145, the undersigned will supply the Partnership with evidence
of compliance with such Rule, in the form of a letter in the form of Annex I
hereto. The undersigned understands that the Partnership may instruct its
transfer agent to withhold the transfer of any KM Units disposed of by the
undersigned, but that upon receipt of such evidence of compliance the transfer
agent shall effectuate the transfer of KM Units sold as indicated in the letter.
 
    The undersigned acknowledges and agrees that the appropriate legends will be
placed on certificates representing KM Units received by the undersigned in the
Transactions or held by a transferee thereof, which legends will be removed by
delivery of substitute certificates upon receipt of an opinion in form and
substance reasonably satisfactory to the Partnership from independent counsel
reasonably satisfactory to the Partnership to the effect that such legends are
no longer required for purposes of the Act.
 
    The undersigned acknowledges that (i) the undersigned has carefully read
this letter and understands the requirements hereof and the limitations imposed
upon the distribution, sale, transfer or other disposition of KM Units and (ii)
the receipt by the Partnership of this letter is an inducement to the
Partnership's obligations to consummate the Transactions.

Ladies and Gentlemen:
 
    On             the undersigned sold the limited partnership common units
("Units") of Kinder Morgan Energy Partners, L.P., a Delaware master limited
partnership (the "Partnership"), described below in the space provided for that
purpose. The Units were received by the undersigned in connection with the
transactions between the Partnership and Santa Fe Pacific Pipeline Partners,
L.P.
 
    Based upon the most recent report or statement filed by the Partnership with
the Securities and Exchange Commission, the Units sold by the undersigned were
within the prescribed limitations set forth in paragraph (e) of Rule 144
promulgated under the Securities Act of 1933, as amended (the "Act").
 
    The undersigned hereby represents that the Units were sold in "brokers'
transactions" within the meaning of Section 4(4) of the Act or in transactions
directly with a "market maker" as that term is defined in Section 3(a)(38) of
the Securities Exchange Act of 1934, as amended. The undersigned further
represents that the undersigned has not solicited or arranged for the
solicitation of orders to buy the Units, and that the undersigned has not made
any payment in connection with the offer or sale of the Units to any person
other than to the broker who executed the order in respect of such sale.
 
                                          Very truly yours,
 
                                          [Name]

                                   ARTICLE I
                             ORGANIZATIONAL MATTERS
 
    1.1  FORMATION AND CONTINUATION.  On August 6, 1992, the General Partner and
the Organizational Limited Partner formed the Partnership as a limited
partnership pursuant to the provisions of the Delaware Act. On February 6, 1992,
the General Partner and the Organizational Limited Partner amended and restated
the Partnership's original Agreement of Limited Partnership in its entirety (the
"First Amended and Restated Agreement of Limited Partnership") and, subject to
the provisions of the First Amended and Restated Agreement of Limited
Partnership, the General Partner and the Organizational Limited Partner agreed
to continue the Partnership as a limited partnership pursuant to the provisions
of the Delaware Act. The General Partner and the Limited Partners hereby further
amend and restate the First Amended and Restated Agreement of Limited
Partnership. Except as expressly provided to the contrary in this Agreement, the
rights and obligations of the Parties and the administration, dissolution and
termination of the Partnership shall be governed by the Delaware Act. All
Partnership Interests shall constitute personal property of the owner thereof
for all purposes.
 
    1.2  NAME.  The name of the Partnership shall be "Kinder Morgan Energy
Partners, L.P." The Partnership's business may be conducted under any other name
or names deemed necessary or appropriate by the General Partner, including,
without limitation, the name of the General Partner or any Affiliate thereof.
The words "Limited Partnership," "L.P.," "Ltd." or similar words or letters
shall be included in the Partnership's name where necessary for the purposes of
complying with the laws of any jurisdiction that so requires. The General
Partner in its sole discretion may change the name of the Partnership at any
time and from time to time and shall notify the Limited Partners of such change
in the next regular communication to Limited Partners.
 
    1.3  REGISTERED OFFICE; PRINCIPAL OFFICE.  Unless and until changed by the
General Partner, the registered office of the Partnership in the State of
Delaware shall be located at The Corporation Trust Center, 1209 Oregon Street,

service of process on the Partnership in the State of Delaware at such
registered office shall be The Corporation Trust Company. The principal office
of the Partnership and the address of the General Partner shall be 1301 McKinney
Street, Suite 3450, Houston, Texas 77010, or such other place as the General
Partner may from time to time designate by notice to the Limited Partners. The
Partnership may maintain offices at such other place or places within or outside
the State of Delaware as the General Partner deems necessary or appropriate.
 
    1.4  POWER OF ATTORNEY.  (a) Each Limited Partner and each Assignee hereby
constitutes and appoints each of the General Partner and, if a Liquidator shall
have been selected pursuant to Section 14.3, the Liquidator severally (and any
successor to either thereof by merger, transfer, assignment, election or
otherwise) and each of their authorized officers and attorneys-in-fact, with
full power of substitution, as his true and lawful agent and attorney-in-fact,
with full power and authority in his name, place and stead, to:
 
           (i) execute, swear to, acknowledge, deliver, file and record in the
       appropriate public offices (A) all certificates, documents and other
       instruments (including, without limitation, this Agreement and the
       Certificate of Limited Partnership and all amendments or restatements
       thereof) that the General Partner or the Liquidator deems necessary or
       appropriate to form, qualify or continue the existence or qualification
       of the Partnership as a limited partnership (or a partnership in which
       the limited partners have limited liability) in the State of Delaware and
       in all other jurisdictions in which the Partnership may conduct business
       or own property; (B) all certificates, documents and other instruments
       that the General Partner or the Liquidator deems necessary or
<PAGE>
       appropriate to reflect, in accordance with its terms, any amendment,
       change, modification or restatement of this Agreement; (C) all
       certificates, documents and other instruments (including, without
       limitation, conveyances and a certificate of cancellation) that the
       General Partner or the Liquidator deems necessary or appropriate to
       reflect the dissolution and liquidation of the Partnership pursuant to
       the terms of this Agreement; (D) all certificates, documents and other
       instruments relating to the admission, withdrawal, removal or
       substitution of any Partner pursuant to, or other events described in,
       Article XI, XII, XIII or XIV or the Capital Contribution of any Partner;
       (E) all certificates, documents and other instruments relating to the
       determination of the rights, preferences and privileges of any class or
       series of Units or other Partnership Securities issued pursuant to
       Section 4.4; and (F) all certificates, documents and other instruments
       (including, without limitation, agreements and a certificate of merger)
       relating to a merger or consolidation of the Partnership pursuant to
       Article XVI; and
 
           (ii) execute, swear to, acknowledge, deliver, file and record all
       ballots, consents, approvals, waivers, certificates, documents and other
       instruments necessary or appropriate, in the sole discretion of the
       General Partner or the Liquidator, to make, evidence, give, confirm or
       ratify any vote, consent, approval, agreement or other action that is
       made or given by the Partners hereunder or is consistent with the terms
       of this Agreement or is necessary or appropriate, in the sole discretion
       of the General Partner or the Liquidator, to effectuate the terms or
       intent of this Agreement; PROVIDED, that when required by Section 15.3 or
       any other provision of this Agreement that establishes a percentage of
       the Limited Partners or of the Limited Partners of any class or series
       required to take any action, the General Partner or the Liquidator may
       exercise the power of attorney made in this Section 1.4(a)(ii) only after
       the necessary vote, consent or approval of the Limited Partners or of the
       Limited Partners of such class or series, as applicable.
 
Nothing contained in this Section 1.4(a) shall be construed as authorizing the
General Partner to amend this Agreement except in accordance with Article XV or
as may be otherwise expressly provided for in this Agreement.
 
    (b) The foregoing power of attorney is hereby declared to be irrevocable and
a power coupled with an interest, and it shall survive and not be affected by
the subsequent death, incompetency, disability, incapacity, dissolution,
bankruptcy or termination of any Limited Partner or Assignee and the transfer of
all or any portion of such Limited Partner's or Assignee's Partnership Interest
and shall extend to such Limited Partner's or Assignee's heirs, successors,
assigns and personal representatives. Each such Limited Partner or Assignee
hereby agrees to be bound by any representation made by the General Partner or
the Liquidator acting in good faith pursuant to such power of attorney; and each
such Limited Partner or Assignee hereby waives any and all defenses that may be
available to contest, negate or disaffirm the action of the General Partner or
the Liquidator taken in good faith under such power of attorney. Each Limited
Partner or Assignee shall execute and deliver to the General Partner or the
Liquidator, within 15 days after receipt of the General Partner's or the
Liquidator's request therefor, such further designation, powers of attorney and
other instruments as the General Partner or the Liquidator deems necessary to
effectuate this Agreement and the purposes of the Partnership.
 
    1.5  TERM.  The Partnership commenced upon the filing of the Certificate of
Limited Partnership in accordance with the Delaware Act and shall continue in
existence until the close of Partnership business on December 31, 2082, or until
the earlier termination of the Partnership in accordance with the provisions of
Article XIV.
 
    1.6  POSSIBLE RESTRICTIONS ON TRANSFER.  Notwithstanding anything to the
contrary contained in this Agreement, in the event of (a) the enactment (or
imminent enactment) of any legislation, (b) the publication of any temporary or
final regulation by the Treasury Department, (c) any ruling by the Internal
Revenue Service or (d) any judicial decision, that, in any such case, in the
Opinion of Counsel, would result in the taxation of the Partnership as an
association taxable as a corporation or would otherwise result in the
Partnership's being taxed as an entity for federal income tax purposes, then,
the General Partner may impose such restrictions on the transfer of Units or
Partnership Interests as may be required, in the Opinion of Counsel, to prevent
the Partnership for federal income tax purposes from being taxed as an
 
                                      D-2
<PAGE>
association taxable as a corporation or otherwise as an entity, including,
without limitation, making any amendments to this Agreement as the General
Partner in its sole discretion may determine to be necessary or appropriate to
impose such restrictions, provided, that any such amendment to this Agreement
that would result in the delisting or suspension of trading of any class of
Units on any National Securities Exchange on which such class of Units is then
traded must be approved by at least two-thirds of the Outstanding Units of such
class (excluding the vote in respect of Units held by the General Partner and
its Affiliates).

                                  DEFINITIONS

       withheld with respect to, all or less than all of the Partners shall not
       be considered cash disbursements of the Partnership that reduce Available

       distribution of Available Cash to such Partners. Alternatively, in the
       discretion of the General Partner, such taxes (if pertaining to all

    4.6  CAPITAL ACCOUNTS.  (a) The Partnership shall maintain for each Partner
(or a beneficial owner of Units or Deferred Participation Units held by a
nominee in any case in which the nominee has furnished the identity of such
owner to the Partnership in accordance with Section 6031(c) of the Code or any
other method acceptable to the General Partner in its sole discretion) owning a
Partnership Interest a separate Capital Account with respect to such Partnership
Interest in accordance with the rules of Treasury Regulation Section
1.704-1(b)(2)(iv). Such Capital Account shall be INCREASED by (i) the amount of
all Capital Contributions made to the Partnership with respect to such
Partnership Interest pursuant to this Agreement and (ii) all items of
Partnership income and gain (including, without limitation, income and gain
exempt from tax) computed in accordance with Section 4.6(b) and allocated with
respect to such Partnership Interest pursuant to Sections 4.2 and 5.1, and
DECREASED by (x) the amount of cash or Net Agreed Value of all actual and deemed
distributions of cash or property made with respect to such Partnership Interest
pursuant to this Agreement and (y) all items of Partnership deduction and loss
computed in accordance with Section 4.6(b) and allocated with respect to such
Partnership Interest pursuant to Section 5.1.
 
    (b) For purposes of computing the amount of any item of income, gain, loss
or deduction to be reflected in the Partners' Capital Accounts, the
determination, recognition and classification of any such item shall be the same
as its determination, recognition and classification for federal income tax
purposes (including, without limitation, any method of depreciation, cost
recovery or amortization used for that purpose), PROVIDED, that:
 
        (i) Solely for purposes of this Section 4.6, the Partnership shall be
    treated as owning directly its proportionate share (as determined by the
    General Partner based upon the provisions of the Operating Partnership
    Agreement) of all property owned by the Operating Partnership.
 
        (ii) All fees and other expenses incurred by the Partnership to promote
    the sale of (or to sell) a Partnership Interest that can neither be deducted
    nor amortized under Section 709 of the Code, if any, shall, for purposes of
    Capital Account maintenance, be treated as an item of deduction at the time
 
                                      D-19
<PAGE>
    such fees and other expenses are incurred and shall be allocated among the
    Partners pursuant to Section 5.1.
 
        (iii) Except as otherwise provided in Treasury Regulation Section
    1.704-1(b)(2)(iv)(m), the computation of all items of income, gain, loss and
    deduction shall be made without regard to any election under Section 754 of
    the Code which may be made by the Partnership and, as to those items
    described in Section 705(a)(1)(B) or 705(a)(2)(B) of the Code, without
    regard to the fact that such items are not includable in gross income or are
    neither currently deductible nor capitalized for federal income tax
    purposes.
 
        (iv) Any income, gain or loss attributable to the taxable disposition of
    any Partnership property shall be determined as if the adjusted basis of
    such property as of such date of disposition were equal in amount to the
    Partnership's Carrying Value with respect to such property as of such date.
 
        (v) In accordance with the requirements of Section 704(b) of the Code,
    any deductions for depreciation, cost recovery or amortization attributable
    to any Contributed Property shall be determined as if the adjusted basis of
    such property on the date it was acquired by the Partnership were equal to
    the Agreed Value of such property. Upon an adjustment pursuant to Section
    4.6(d) to the Carrying Value of any Partnership property subject to
    depreciation, cost recovery or amortization, any further deductions for such
    depreciation, cost recovery or amortization attributable to such property
    shall be determined (A) as if the adjusted basis of such property were equal
    to the Carrying Value of such property immediately following such adjustment
    and (B) using a rate of depreciation, cost recovery or amortization derived
    from the same method and useful life (or, if applicable, the remaining
    useful life) as is applied for federal income tax purposes; PROVIDED,
    HOWEVER, that, if the asset has a zero adjusted basis for federal income tax
    purposes, depreciation, cost recovery or amortization deductions shall be
    determined using any reasonable method that the General Partner may adopt.
 
        (vi) If the Partnership's adjusted basis in a depreciable or cost
    recovery property is reduced for federal income tax purposes pursuant to
    Section 48(q)(1) or 48(q)(3) of the Code, the amount of such reduction
    shall, solely for purposes hereof, be deemed to be an additional
    depreciation or cost recovery deduction in the year such property is placed
    in service and shall be allocated among the Partners pursuant to Section
    5.1. Any restoration of such basis pursuant to Section 48(q)(2) of the Code
    shall, to the extent possible, be allocated in the same manner to the
    Partners to whom such deemed deduction was allocated.
 
(c) (i) Except as otherwise provided in Section 4.6(c)(ii), a transferee of a
    Partnership Interest shall succeed to a pro rata portion of the Capital
    Account of the transferor relating to the Partnership Interest so
    transferred, provided, however, that, if the transfer causes a termination
    of the Partnership under Section 708(b)(1)(B) of the Code, the Partnership's
    properties shall be deemed to have been distributed in liquidation of the
    Partnership to the Partners (including any transferee of a Partnership
    Interest that is a party to the transfer causing such termination) pursuant
    to Section 14.3 and 14.4 and recontributed by such Partners in
    reconstitution of the Partnership. Any such deemed distribution shall be
    treated as an actual distribution for purposes of this Section 4.6. In such
    event, the Carrying Values of the Partnership properties shall be adjusted
    immediately prior to such deemed distribution pursuant to Section 4.6(d)(ii)
    and such Carrying Values shall then constitute the Agreed Values of such
    properties upon such deemed contribution to the reconstituted Partnership.
    The Capital Accounts of such reconstituted Partnership shall be maintained
    in accordance with the principles of this Section 4.6.
 
        (ii) Immediately prior to the conversion of a Deferred Participation
    Unit into a Common Unit pursuant to Section 5.7(c) or the sale, exchange or
    other disposition of a Deferred Participation Unit by a holder thereof, the
    Capital Account maintained for such Person with respect to its Deferred
    Participation Units will (A) first, be allocated to the Deferred
    Participation Units to be transferred in an amount equal to the product of
    (x) the number of such Deferred Participation Units to be
 
                                      D-20
<PAGE>
    transferred and (y) the Per Unit Capital Amount for a Common Unit, and (B)
    second, any remaining balance in such Capital Account will be retained by
    the transferor, regardless of whether it has retained any Deferred
    Participation Units. Following any such allocation, the transferor's Capital
    Account, if any, maintained with respect to the retained Deferred
    Participation Units, if any, will have a balance equal to the amount
    allocated under clause (B) hereinabove, and the transferee's Capital Account
    established with respect to the transferred Deferred Participation Units
    will have a balance equal to the amount allocated under clause (A)
    hereinabove.
 
(d) (i) Consistent with the provisions of Treasury Regulation Section
    1.704-1(b)(2)(iv)(f), on an issuance of additional Units for cash or
    Contributed Property or the conversion of the General Partner's Partnership
    Interest to Common Units pursuant to Section 13.3(b), the Capital Account of
    all Partners and the Carrying Value of each Partnership property immediately
    prior to such issuance shall be adjusted upward or downward to reflect any
    Unrealized Gain or Unrealized Loss attributable to such Partnership
    property, as if such Unrealized Gain or Unrealized Loss had been recognized
    on an actual sale of each such property immediately prior to such issuance
    and had been allocated to the Partners at such time pursuant to Section 5.1.
    In determining such Unrealized Gain or Unrealized Loss, the aggregate cash
    amount and fair market value of all Partnership assets (including, without
    limitation, cash or cash equivalents) immediately prior to the issuance of
    additional Units shall be determined by the General Partner using such
    reasonable method of valuation as it may adopt; provided, however, the
    General Partner, in arriving at such valuation, must take fully into account
    the Limited Partner Equity Value, the General Partner Equity Value, and the
    Special Limited Partner Book Capital, at such time. The General Partner
    shall allocate such aggregate value among the assets of the Partnership (in
    such manner as it determines in its sole discretion to be reasonable) to
    arrive at a fair market value for individual properties.
 
        (ii) In accordance with Treasury Regulation Section
    1.704-1(b)(2)(iv)(F), immediately prior to any actual or deemed distribution
    to a Partner of any Partnership property (other than a distribution of cash
    that is not in redemption or retirement of a Partnership Interest), the
    Capital Accounts of all Partners and the Carrying Value of such Partnership
    property shall be adjusted upward or downward to reflect any Unrealized Gain
    or Unrealized Loss attributable to such Partnership property, as if such
    Unrealized Gain or Unrealized Loss had been recognized in a sale of such
    property immediately prior to such distribution for an amount equal to its
    fair market value, and had been allocated to the Partners, at such time,
    pursuant to Section 5.1. Any Unrealized Gain or Unrealized Loss attributable
    to such property shall be allocated in the same manner as Net Termination
    Gain or Net Termination Loss pursuant to Section 5.1(c); PROVIDED, HOWEVER,
    that, in making any such allocation, Net Termination Gain or Net Termination
    Loss actually realized shall be allocated first. In determining such
    Unrealized Gain or Unrealized Loss the aggregate cash amount and fair market
    value of all Partnership assets (including, without limitation, cash or cash
    equivalents) immediately prior to a distribution shall (A) in the case of a
    deemed distribution occurring as a result of a termination of the
    Partnership pursuant to Section 708 of the Code, be determined and allocated
    in the same manner as that provided in Section 4.6(d)(i) or (B) in the case
    of the liquidating distribution pursuant to Section 14.3 or 14.4, be
    determined and allocated by the Liquidator using such reasonable method of
    valuation as it may adopt.
 
    4.7  INTEREST.  No interest shall be paid by the Partnership on Capital
Contributions or on balances in Partners' Capital Accounts.
 
    4.8  NO WITHDRAWAL.  No Partner shall be entitled to withdraw any part of
his Capital Contributions (including, without limitation, with respect to APIs)
or its Capital Account or to receive any distribution from the Partnership,
except as provided in Section 4.2, Articles V, XIII and XIV and the Omnibus
Agreement.
 
                                      D-21
<PAGE>
    4.9  LOANS FROM PARTNERS.  Loans by a Partner to the Partnership shall not
constitute Capital Contributions. If any Partner shall advance funds to the
Partnership in excess of the amounts required hereunder to be contributed by it
to the capital of the Partnership, the making of such excess advances shall not
result in any increase in the amount of the Capital Account of such Partner. The
amount of any such excess advances shall be a debt obligation of the Partnership
to such Partner and shall be payable or collectible only out of the Partnership
assets in accordance with the terms and conditions upon which such advances are
made.
 
    4.10  NO FRACTIONAL UNITS.  No fractional Units shall be issued by the
Partnership.
 
    4.11  SPLITS AND COMBINATIONS.  (a) Subject to Section 4.11(d), the General
Partner may make a pro rata distribution of Units or other Partnership
Securities to all Record Holders or may effect a subdivision or combination of
Units or other Partnership Securities; PROVIDED, HOWEVER, that after any such
distribution, subdivision or combination, each Partner shall have the same
Percentage Interest in the Partnership as before such distribution, subdivision
or combination.
 
    (b) Whenever such a distribution, subdivision or combination of Units or
other Partnership Securities is declared, the General Partner shall select a
Record Date as of which the distribution, subdivision or combination shall be
effective and shall send notice of the distribution, subdivision or combination
at least 20 days prior to such Record Date to each Record Holder as of the date
not less than 10 days prior to the date of such notice. The General Partner also
may cause a firm of independent public accountants selected by it to calculate
the number of Units to be held by each Record Holder after giving effect to such
distribution, subdivision or combination. The General Partner shall be entitled
to rely on any certificate provided by such firm as conclusive evidence of the
accuracy of such calculation.
 
    (c) Promptly following any such distribution, subdivision or combination,
the General Partner may cause Certificates to be issued to the Record Holders of
Units as of the applicable Record Date representing the new number of Units held
by such Record Holders, or the General Partner may adopt such other procedures
as it may deem appropriate to reflect such distribution, subdivision or
combination; provided, however, if any such distribution, subdivision or
combination results in a smaller total number of Units Outstanding, the General
Partner shall require, as a condition to the delivery to a Record Holder of such
new Certificate, the surrender of any Certificate held by such Record Holder
immediately prior to such Record Date.
 
    (d) The Partnership shall not issue fractional Units upon any distribution,
subdivision or combination of Units. If a distribution, subdivision or
combination of Units would result in the issuance of fractional Units but for
the provisions of Section 4.10 and this Section 4.11(d), each fractional Unit
shall be rounded to the nearest whole Unit (and a 0.5 Unit shall be rounded to
the next higher Unit).

       Partners pursuant to this Section 5.1(a)(ii) for the current taxable year

           (i) FIRST, 100% to the General Partner and the Limited Partners, in
       accordance with their respective Percentage Interests, until the
       aggregate Net Losses allocated pursuant to this Section 5.1(b)(i) for the
       current taxable year and all previous taxable years is equal to the
       aggregate Net Income allocated to such Partners pursuant to Section
       5.1(a)(v) for all previous taxable years;
 
           (ii) SECOND, 100% to the General Partner and the Limited Partners in
       accordance with their respective Percentage Interests; PROVIDED, that the
       Net Losses shall not be allocated pursuant to this Section 5.1(b)(ii) to
       the extent that such allocation would cause any Partner to have a deficit
       balance in its Adjusted Capital Account at the end of such taxable year
       (or increase any existing deficit balance in its Adjusted Capital
       Account);
 
           (iii) THIRD, 100% to the Special Limited Partners, each in the
       proportion that the respective number of APIs held by such Special
       Limited Partner bears to the total number of APIs then Outstanding,
       PROVIDED, that Net Losses shall not be allocated pursuant to this Section
       5.1(b)(iii) to the extent that such allocation would cause any Special
       Limited Partner to have a deficit balance in its Adjusted Capital Account
       at the end of such taxable year (or increase any existing deficit balance
       in its Adjusted Capital Account);
 
           (iv) FOURTH, if such taxable period ends prior to the conversion of
       the last outstanding Deferred Participation Unit, pursuant to Section
       5.7(b) hereof, 100% to the Partners holding Deferred Participation Units,
       in the proportion of the number of Deferred Participation Units held by
       each such Partner to the total number of Deferred Participation Units
       then outstanding; provided, that Net Losses shall not be allocated
       pursuant to this Section 5.1(b)(iv) to the extent that such allocation
       would cause any Partner holding such Deferred Participation Units to have
       a
 
                                      D-23

       deficit balance in its Adjusted Capital Account at the end of such
       taxable year (or increase any existing deficit balance in its Adjusted
       Capital Account); and
 
           (v) FIFTH, the balance, if any, 100% to the General Partner.
 
        (C)  NET TERMINATION GAINS AND LOSSES.  After giving effect to the
    allocations in Section 4.2 and the special allocations set forth in Section
    5.1(d), all items of income, gain, loss and deduction taken into account in
    computing Net Termination Gain or Net Termination Loss for such taxable
    period shall be allocated in the same manner as such Net Termination Gain or
    Net Termination Loss is allocated hereunder. All allocations under this
    Section 5.1(c) shall be made after Capital Account balances have been
    adjusted by all other allocations provided under this Section 5.1 and after
    all distributions of Available Cash provided under Section 5.4 have been
    made with respect to the taxable period ending on the date of the
    Partnership's liquidation pursuant to Section 14.3.
 
           (i) If a Net Termination Gain is recognized (or deemed recognized
       pursuant to Section 4.6(d)) from Termination Capital Transactions, such
       Net Termination Gain shall be allocated between the General Partner and
       the Limited Partners in the following manner (and the Adjusted Capital
       Accounts of the Partners shall be increased by the amount so allocated in
       each of the following subclauses, in the order listed, before an
       allocation is made pursuant to the next succeeding subclause);
 
               (A) FIRST, to each Partner having a deficit balance in its
           Adjusted Capital Account, in the proportion that such deficit balance
           bears to the total deficit balances in the Adjusted Capital Accounts
           of all Partners, until each such Partner has been allocated Net
           Termination Gain equal to any such deficit balance in its Adjusted
           Capital Account;
 
               (B) SECOND, 99% to all Limited Partners, in accordance with their
           respective Percentage Interests, and 1% to the General Partner until
           the Adjusted Capital Account in respect of each Common Unit then
           Outstanding is equal to its Unrecovered Initial Unit Price;
 
               (C) THIRD, 99% to the Limited Partners, in accordance with their
           respective Percentage Interests, and 1% to the General Partner until
           the Adjusted Capital Account in respect of each Common Unit then
           Outstanding is equal to the sum of (1) its Unrecovered Initial Unit
           Price PLUS (2) the Minimum Quarterly Distribution for the quarter
           during which such Net Termination Gain is recognized, reduced by any
           distribution pursuant to Section 5.4(a) with respect to such Common
           Unit for such quarter (the amount determined pursuant to this clause
           (2) is hereinafter defined as the "UNPAID MQD");
 
               (D) FOURTH, 99% to the Limited Partners, in accordance with their
           respective Percentage Interests, and 1% to the General Partner until
           the Adjusted Capital Account in respect of each Common Unit then
           Outstanding is equal to the sum of (1) its Unrecovered Initial Unit
           Price, PLUS (2) its Unpaid MQD, if any, PLUS, (3) its Cumulative
           Common Unit Arrearage, if any;
 
               (E) FIFTH, if such Termination Capital Transaction occurs (or is
           deemed to occur) prior to the conversion of the last Outstanding
           Deferred Participation Unit, pursuant to Section 5.7(b), 100% to the
           Partners holding such Deferred Participation Units, in the ratio of
           the number of Deferred Participation Units held by each such Partner
           to the total number of Deferred Participation Units then outstanding,
           in the amount which will increase the Adjusted Capital Account of
           each such Partner maintained with respect to such Deferred
           Participation Units to that amount which equals the Unrecovered
           Deferred Participation Unit Capital attributable to such Deferred
           Participation Units, determined for the taxable year (or portion
           thereof) to which this allocation of gain relates and taking into
           account any allocations made pursuant to subparagraphs (A) , (B) and
           (C) of this Section 5.1(c)(i);

<PAGE>
               (F) SIXTH, if such Termination Capital Transaction occurs (or is
           deemed to occur) prior to the redemption of all APIs then
           Outstanding, 100% to the Special Limited Partners holding such APIs,
           each in the proportion that the respective number of APIs held by
           such Special Limited Partner bears to the total number of APIs then
           Outstanding, in the amount which will increase each Special Limited
           Partner's Adjusted Capital Account in respect of its APIs to that
           amount which equals the Unrecovered API Capital balance attributable
           to such APIs;
 
               (G) SEVENTH, 99% to all Limited Partners, in accordance with
           their respective Percentage Interests, and 1% to the General Partner
           until the Adjusted Capital Account in respect of each Common Unit
           then Outstanding is equal to the sum of (aa) its Unrecovered Initial
           Unit Price, PLUS (bb) its Unpaid MQD, PLUS (cc) its Cumulative Common
           Unit Arrearage, if any, PLUS (dd) the excess of (i) the First Target
           Distribution LESS the Minimum Quarterly Distribution for each quarter
           of the Partnership's existence over (ii) the amount of any
           distribution of Cash from Operations that was distributed pursuant to
           Section 5.4(d) (the sum of (aa) PLUS (bb) PLUS (cc) PLUS (dd) is
           hereinafter defined as the "FIRST LIQUIDATION TARGET AMOUNT");
 
               (H) EIGHTH, 85.8673% to all Limited Partners, in accordance with
           their respective Percentage Interests, and 14.1327% to the General
           Partner until the Adjusted Capital Account in respect of each Common
           Unit then Outstanding is equal to the sum of (aa) the First
           Liquidation Target Amount, PLUS (bb) the excess of (i) the Second
           Target Distribution LESS the First Target Distribution for each
           quarter of the Partnership's existence over (ii) the amount of any
           distributions of Cash from Operations that was distributed pursuant
           to Section 5.4(e) (the sum of (aa) PLUS (bb) is hereinafter defined
           as the "SECOND LIQUIDATION TARGET AMOUNT");
 
               (I) NINTH, 75.7653% to all Limited Partners, in accordance with
           their respective Percentage Interests, and 24.2347% to the General
           Partner until the Adjusted Capital Account in respect of each Common
           Unit then Outstanding is equal to the sum of (aa) the Second
           Liquidation Target Amount, PLUS (bb) the excess of (i) the Third
           Target Distribution LESS the Second Target Distribution for each
           quarter of the Partnership's existence over (ii) the amount of any
           distributions of Cash from Operations that was distributed pursuant
           to Section 5.4(f); and
 
               (J) FINALLY, any remaining amount 50.5102% to all Limited
           Partners, in accordance with their respective Percentage Interests,
           and 49.4898% to the General Partner.
 
           (ii) If a Net Termination Loss is recognized (or deemed recognized
       pursuant to Section 4.6(d)) from Termination Capital Transactions, such
       Net Termination Loss shall be allocated to the Partners in the following
       manner:
 
               (A) FIRST, 100% to the General Partner and the Limited Partners
           in proportion to, and to the extent of, the positive balances in
           their respective Adjusted Capital Accounts;
 
               (B) SECOND, if such Termination Capital Transaction occurs (or is
           deemed to occur) prior to the redemption of all APIs then
           Outstanding, 100% to the Special Limited Partners, each in the
           proportion that the respective number of APIs held by such Special
           Limited Partner bears to the total number of APIs then Outstanding,
           to the extent of the positive balance in each such Special Limited
           Partner's respective Adjusted Capital Account maintained with respect
           to its APIs;
 
               (C) THIRD, if such Termination Capital Transaction occurs (or is
           deemed to occur) prior to the conversion of the last outstanding
           Deferred Participation Unit, pursuant to Section 5.7(b) hereof, 100%
           to the Partners holding Deferred Participation Units each in the
 
                                      D-25
<PAGE>
           proportion that the respective number of Deferred Participation Units
           held by such Partner bears to the total number of Deferred
           Participation Units then outstanding, to the extent of the positive
           balances in their respective Adjusted Capital Accounts maintained
           with respect to such Deferred Participation Units; and
 
               (D) FOURTH, the balance, if any, 100% to the General Partner.
 
        (D)  SPECIAL ALLOCATIONS.  Notwithstanding any other provision of this
    Section 5.1, the following special allocations shall be made for such
    taxable period:
 
           (I)  PARTNERSHIP MINIMUM GAIN CHARGEBACK.  Notwithstanding any other
       provision of this Section 5.1, if there is a net decrease in Partnership
       Minimum Gain during any Partnership taxable period, each Partner shall be
       allocated items of Partnership income and gain for such period (and, if
       necessary, subsequent periods) in the manner and amounts provided in
       Treasury Regulation Sections 1.704-2(f)(6), 1.704-2(g)(2) and
       1.704-2(j)(2)(i), or any successor provision. For purposes of this
       Section 5.1(d), each Partner's Adjusted Capital Account balance shall be
       determined, and the allocation of income or gain required hereunder shall
       be effected, prior to the application of any other allocations pursuant
       to this Section 5.1(d) with respect to such taxable period (other than an
       allocation pursuant to Sections 5.1(d)(vi) and 5.1(d)(vii)). This Section
       5.1(d)(i) is intended to comply with the Partnership Minimum Gain
       chargeback requirement in Treasury Regulation Section 1.704-2(f) and
       shall be interpreted consistently therewith.
 
           (II)  CHARGEBACK OF PARTNER NONRECOURSE DEBT MINIMUM
       GAIN.  Notwithstanding the other provisions of this Section 5.1 (other
       than Section 5.1(d)(i)), except as provided in Treasury Regulation
       Section 1.704-2(i)(4), if there is a net decrease in Partner Nonrecourse
       Debt Minimum Gain during any Partnership taxable period, any Partner with
       a share of Partner Nonrecourse Debt Minimum Gain at the beginning of such
       taxable period shall be allocated items of Partnership income and gain
       for such period (and, if necessary, subsequent periods) in the manner and
       amounts provided in Treasury Regulation Sections 1.704-2(i)(4) and
       1.704-2(j)(2)(ii), or any successor provisions. For purposes of this
       Section 5.1(d), each Partner's Adjusted Capital Account balance shall be
       determined, and the allocation of income or gain required hereunder shall
       be effected, prior to the application of any other allocations pursuant
       to this Section 5.1(d), other than Section 5.1(d)(i) and other than an
       allocation pursuant to Sections 5.1(d)(vi) and 5.1(d)(vii), with respect
       to such taxable period. This Section 5.1(d)(ii) is intended to comply
       with the chargeback of items of income and gain requirement in Treasury
       Regulation Section 1.704-2(f)(4) and shall be interpreted consistently
       therewith.
 
           (III)  PRIORITY ALLOCATIONS.  All or a portion of the remaining items
       of Partnership gross income or gain for the taxable period, if any, shall
       be allocated 100% to the General Partner until the aggregate amount of
       such items allocated to the General Partner under this paragraph (iii)
       for the current taxable period and all previous taxable periods is equal
       to the cumulative amount of cash distributed to the General Partner (or
       its assignee) as an Incentive Distribution from the Closing Date to a
       date 45 days after the end of the current taxable period.
 
           (IV)  QUALIFIED INCOME OFFSET.  In the event any Partner unexpectedly
       receives any adjustments, allocations or distributions described in
       Treasury Regulation Sections 1.704-1(b)(2)(ii)(D)(4),
       1.704-1(b)(2)(ii)(D)(5), or 1.704-1(b)(2)(ii)(D)(6), items of Partnership
       income and gain shall be specifically allocated to such Partner in an
       amount and manner sufficient to eliminate, to the extent required by the
       Treasury regulations promulgated under Section 704(b) of the Code, the
       deficit balance, if any, in its Adjusted Capital Account created by such
       adjustments, allocations or distributions as quickly as possible unless
       such deficit balance is otherwise eliminated pursuant to Section
       5.1(d)(i) or (ii).
 
           (V)  GROSS INCOME ALLOCATIONS.  In the event any Partner has a
       deficit balance in its Adjusted Capital Account at the end of any
       Partnership taxable period, such Partner shall be specially allocated
       items of Partnership gross income and gain in the amount of such excess
       as quickly as
 
                                      D-26
<PAGE>
       possible; PROVIDED, that an allocation pursuant to this Section 5.1(d)(v)
       shall be made only if and to the extent that such Partner would have a
       deficit balance in its Adjusted Capital Account after all other
       allocations provided for in this Section 5.1 have been tentatively made
       as if this Section 5.1(d)(v) were not in this Agreement.
 
           (VI)  NONRECOURSE DEDUCTIONS.  Nonrecourse Deductions for any taxable
       period shall be allocated to the Partners in accordance with their
       respective Percentage Interests. If the General Partner determines in its
       good faith discretion that the Partnership's Nonrecourse Deductions must
       be allocated in a different ratio to satisfy the safe harbor requirements
       of the Treasury regulations promulgated under Section 704(b) of the Code,
       the General Partner is authorized, upon notice to the Limited Partners,
       to revise the prescribed ratio to the numerically closest ratio that does
       satisfy such requirements.
 
           (VII)  PARTNER NONRECOURSE DEDUCTIONS.  Partner Nonrecourse
       Deductions for any taxable period shall be allocated 100% to the Partner
       that bears the Economic Risk of Loss with respect to the Partner
       Nonrecourse Debt to which such Partner Nonrecourse Deductions are
       attributable in accordance with Treasury Regulation Section 1.704-2(i).
       If more than one Partner bears the Economic Risk of Loss with respect to
       a Partner Nonrecourse Debt, such Partner Nonrecourse Deductions
       attributable thereto shall be allocated between or among such Partners in
       accordance with the ratios in which they share such Economic Risk of
       Loss.
 
           (VIII)  NONRECOURSE LIABILITIES.  For purposes of Treasury Regulation
       Section 1.752-3(a)(3), the Partners agree that Nonrecourse Liabilities of
       the Partnership in excess of the sum of (A) the amount of Partnership
       Minimum Gain and (B) the total amount of Nonrecourse Built-in Gain shall
       be allocated among the Partners in accordance with their respective
       Percentage Interests.
 
           (IX)  CODE SECTION 754 ADJUSTMENTS.  To the extent an adjustment to
       the adjusted tax basis of any Partnership asset pursuant to Section
       734(b) or 743(b) of the Code is required, pursuant to Treasury Regulation
       Section 1.704-1(b)(2)(iv)(M), to be taken into account in determining
       Capital Accounts, the amount of such adjustment to the Capital Accounts
       shall be treated as an item of gain (if the adjustment increases the
       basis of the asset) or loss (if the adjustment decreases such basis), and
       such item of gain or loss shall be specially allocated to the Partners in
       a manner consistent with the manner in which their Capital Accounts are
       required to be adjusted pursuant to such Section of the Treasury
       regulations.
 
           (X)  ECONOMIC UNIFORMITY.  At the election of the General Partner
       with respect to any taxable period ending upon, or after, the termination
       of the Deferral Period or the removal of the General Partner under
       circumstances where Cause does not exist, all or a portion of the
       remaining items of Partnership gross income or gain for such taxable
       period, if any, shall be allocated 100% to each Partner holding Deferred
       Participation Units in the proportion of the number of Deferred
       Participation Units held by such Partner to the total number of Deferred
       Participation Units then Outstanding, until each such Partner has been
       allocated an amount of gross income or gain which increases the Capital
       Account maintained with respect to such Deferred Participation Units to
       an amount equal to the product of (A) the number of Deferred
       Participation Units held by such Partner and (B) the Per Unit Capital
       Amount for a Common Unit. The purpose of this allocation is to establish
       uniformity between the Capital Accounts underlying Deferred Participation
       Units and the Capital Accounts underlying Common Units held by Persons
       other than the General Partner and its Affiliates immediately prior to
       the conversion of such Deferred Participation Units into Common Units.
       This allocation method for establishing such economic uniformity will
       only be available to the General Partner if the method for allocating the
       Capital Account maintained with respect to the Deferred Participation
       Units between the transferred and retained Deferred Participation Units
       pursuant to Section 4.6(c)(ii) does not otherwise provide such economic
       uniformity to the Deferred Participation Units.

           (XI)  CURATIVE ALLOCATION.
 
               (A) Notwithstanding any other provision of this Section 5.1,
           other than the Required Allocations, the Required Allocations shall
           be taken into account in making the Agreed Allocations so that, to
           the extent possible, the net amount of items of income, gain, loss
           and deduction allocated to each Partner pursuant to the Required
           Allocations and the Agreed Allocations, together, shall be equal to
           the net amount of such items that would have been allocated to each
           such Partner under the Agreed Allocations had the Required
           Allocations and the related Curative Allocation not otherwise been
           provided in this Section 5.1. Notwithstanding the preceding sentence,
           Required Allocations relating to (1) Nonrecourse Deductions shall not
           be taken into account except to the extent that there has been a
           decrease in Partnership Minimum Gain and (2) Partner Nonrecourse
           Deductions shall not be taken into account except to the extent that
           there has been a decrease in Partner Nonrecourse Debt Minimum Gain.
           Allocations, pursuant to this Section 5.1(d)(xi)(A) shall only be
           made with respect to Required Allocations to the extent the General
           Partner reasonably determines that such allocations will otherwise be
           inconsistent with the economic agreement among the Partners. Further,
           allocations pursuant to this Section 5.1(d)(xi)(A) shall be deferred
           with respect to allocations pursuant to clauses (1) and (2) hereof to
           the extent the General Partner reasonably determines that such
           allocations are likely to be offset by subsequent Required
           Allocations.
 
               (B) The General Partner shall have reasonable discretion, with
           respect to each taxable period, to (1) apply the provisions of
           Section 5.1(d)(xi)(A) in whatever order is most likely to minimize
           the economic distortions that might otherwise result from the
           Required Allocations, and (2) divide all allocations pursuant to
           Section 5.1(d)(xi)(A) among the Partners in a manner that is likely
           to minimize such economic distortions.
 
    5.2  ALLOCATIONS FOR TAX PURPOSES.  (a) Except as otherwise provided herein,
for federal income tax purposes, each item of income, gain, loss and deduction
shall be allocated among the Partners in the same manner as its correlative item
of "book" income, gain, loss or deduction is allocated pursuant to Section 5.1.
 
    (b) In an attempt to eliminate Book-Tax Disparities attributable to a
Contributed Property or Adjusted Property, items of income, gain, loss,
depreciation, amortization and cost recovery deductions shall be allocated for
federal income tax purposes among the Partners as follows:
 
        (i) (A) In the case of a Contributed Property, such items attributable
    thereto shall be allocated among the Partners in the manner provided under
    Section 704(c) of the Code that takes into account the variation between the
    Agreed Value of such property and its adjusted basis at the time of
    contribution; and (B) except as otherwise provided in Section 5.2(b)(iv),
    any item of Residual Gain or Residual Loss attributable to a Contributed
    Property shall be allocated among the Partners in the same manner as its
    correlative item of "book" gain or loss is allocated pursuant to Section
    5.1.
 
        (ii) (A) In the case of an Adjusted Property, such items shall (1)
    FIRST, be allocated among the Partners in a manner consistent with the
    principles of Section 704(c) of the Code to take into account the Unrealized
    Gain or Unrealized Loss attributable to such property and the allocations
    thereof pursuant to Section 4.6(d)(i) or (ii), and (2) SECOND, in the event
    such property was originally a Contributed Property, be allocated among the
    Partners in a manner consistent with Section 5.2(b)(i)(A) ; and (B) except
    as otherwise provided in Section 5.2(b)(iv), any item of Residual Gain or
    Residual Loss attributable to an Adjusted Property shall be allocated among
    the Partners in the same manner as its correlative item of "book" gain or
    loss is allocated pursuant to Section 5.1.
 
                                      D-28
<PAGE>
        (iii) Except as otherwise provided in Section 5.2(b)(iv), all other
    items of income, gain, loss and deduction shall be allocated among the
    Partners in the same manner as their correlative item of "book" gain or loss
    is allocated pursuant to Section 5.1.
 
        (iv) Any items of income, gain, loss or deduction otherwise allocable
    under Section 5.2(b)(i)(B) , 5.2(b)(ii)(B) or 5.2(b)(iii) shall be subject
    to allocation by the General Partner in a manner designed to eliminate, to
    the maximum extent possible, Book-Tax Disparities in a Contributed Property
    or Adjusted Property otherwise resulting from the application of the
    "ceiling" limitation (under Section 704(c) of the Code or Section 704(c)
    principles) to the allocations provided under Section 5.2(b)(i)(A) or
    5.2(b)(ii)(A) .
 
    (c) For the proper administration of the Partnership and for the
preservation of uniformity of the Units (or any class or classes thereof), the
General Partner shall have sole discretion to (i) adopt such conventions as it
deems appropriate in determining the amount of depreciation, amortization and
cost recovery deductions; (ii) make special allocations for federal income tax
purposes of income (including, without limitation, gross income) or deductions;
and (iii) amend the provisions of this Agreement as appropriate (x) to reflect
the proposal or promulgation of Treasury regulations under Section 704(b) or
Section 704(c) of the Code or (y) otherwise to preserve or achieve uniformity of
the Units (or any class or classes thereof). The General Partner may adopt such
conventions, make such allocations and make such amendments to this Agreement as
provided in this Section 5.2(c) only if such conventions, allocations or
amendments would not have a material adverse effect on the Partners, the holders
of any class or classes of Units issued and Outstanding or the Partnership, and
if such allocations are consistent with the principles of Section 704 of the
Code.
 
    (d) The General Partner in its sole discretion may determine to depreciate
the portion of an adjustment under Section 743(b) of the Code attributable to
unrealized appreciation in any Adjusted Property (to the extent of the
unamortized Book-Tax Disparity) using a predetermined rate derived from the
depreciation method and useful life applied to the Partnership's common basis of
such property, despite the inconsistency of such approach with Proposed Treasury
Regulation Section 1.168-2(n) and Treasury Regulation Section 1.167(c)-1(a)(6).
If the General Partner determines that such reporting position cannot reasonably
be taken, the General Partner may adopt a depreciation convention under which
all purchasers acquiring Units in the same month would receive depreciation,
based upon the same applicable rate as if they had purchased a direct interest
in the Partnership's property. If the General Partner chooses not to utilize
such aggregate method, the General Partner may use any other reasonable
depreciation convention to preserve the uniformity of the intrinsic tax
characteristics of any Units that would not have a material adverse effect on
the Limited Partners or the Record Holders of any class or classes of Units.
 
    (e) Any gain allocated to the Partners upon the sale or other taxable
disposition of any Partnership asset shall, to the extent possible, after taking
into account other required allocations of gain pursuant to this Section 5.2, be
characterized as Recapture Income in the same proportions and to the same extent
as such Partners (or their predecessors in interest) have been allocated any
deductions directly or indirectly giving rise to the treatment of such gains as
Recapture Income.
 
    (f) All items of income, gain, loss, deduction and credit recognized by the
Partnership for federal income tax purposes and allocated to the Partners in
accordance with the provisions hereof shall be determined without regard to any
election under Section 754 of the Code which may be made by the Partnership;
PROVIDED, HOWEVER, that such allocations, once made shall be adjusted as
necessary or appropriate to take into account those adjustments permitted or
required by Sections 734 and 743 of the Code.
 
    (g) Each item of Partnership income, gain, loss and deduction attributable
to a transferred Partnership Interest of the General Partner or to transferred
Units shall, for federal income tax purposes, be determined on an annual basis
and prorated on a monthly basis and shall be allocated to the Partners as of
 
                                      D-29
<PAGE>
the opening of the New York Stock Exchange on the first Business Day of each
month; PROVIDED, HOWEVER, that (i) if the Underwriter's over-allotment option is
not exercised, such items for the period beginning on the Closing Date and
ending on the last day of the month in which the Closing Date occurs shall be
allocated to Partners as of the opening of the New York Stock Exchange on the
first Business Day of the next succeeding month or (ii) if the Underwriter's
over-allotment option is exercised, such items for the period beginning on the
Closing Date and ending on the last day of the month in which the Second Time of
Delivery (as defined in the Underwriting Agreement) occurs shall be allocated to
the Partners as of the opening of the New York Stock Exchange on the first
Business Day of the next succeeding month; and PROVIDED, FURTHER, that gain or
loss on a sale or other disposition of any assets of the Partnership other than
in the ordinary course of business shall be allocated to the Partners as of the
opening of the New York Stock Exchange on the first Business Day of the month in
which such gain or loss is recognized for federal income tax purposes. The
General Partner may revise, alter or otherwise modify such methods of allocation
as it determines necessary, to the extent permitted or required by Section 706
of the Code and the regulations or rulings promulgated thereunder.
 
    (h) Allocations that would otherwise be made to a Limited Partner under the
provisions of this Article V shall instead be made to the beneficial owner of
Units held by a nominee in any case in which the nominee has furnished the
identify of such owner to the Partnership in accordance with Section 6031(c) of
the Code or any other method acceptable to the General Partner in its sole
discretion.
 
    5.3  REQUIREMENT AND CHARACTERIZATION OF DISTRIBUTIONS; REDEMPTION OF
APIS.  (a) Within 45 days following the end of each calendar quarter (or
following the period from the Closing Date to September 30, 1992) an amount
equal to 100% of Available Cash with respect to such quarter (or period) shall
be distributed in accordance with this Article V by the Partnership to the
Partners, as of the Record Date selected by the General Partner in its
reasonable discretion. The immediately preceding sentence shall not modify in
any respect the provisions of Section 4.2 regarding the distribution of any
interest or other profit on the initial contributions referred to therein. All
amounts of Available Cash distributed by the Partnership on any date from any
source (other than amounts paid or distributed pursuant to Section 4.2) shall be
deemed to be Cash from Operations until the sum of all amounts of Available Cash
theretofore distributed by the Partnership to Partners pursuant to Section 5.4
and in respect of the redemption of APIs equals the aggregate amount of all Cash
from Operations generated by the Partnership since the Closing Date through the
close of the immediately preceding calendar quarter. Any remaining amounts of
Available Cash distributed by the Partnership on such date (other than amounts
paid or distributed pursuant to Section 4.2) shall, except as otherwise provided
in Section 5.5, be deemed to be Cash from Interim Capital Transactions;
PROVIDED, that if (i) all or any portion of Available Cash with respect to any
calendar quarter distributed by the Partnership would otherwise be deemed to be
Cash from Interim Capital Transactions and (ii) APIs were purchased in respect
of such quarter or any previous quarter under the Omnibus Agreement and the
proceeds therefrom were distributed to the Limited Partners holding Common
Units, then the Available Cash so distributed that would otherwise be deemed to
be Cash from Interim Capital Transactions shall be deemed to be Cash from
Operations to the extent of the proceeds from the purchase of APIs so
distributed.
 
    (b) Notwithstanding the definitions of Available Cash and Cash from
Operations contained herein, (i) cash receipts of the Partnership from the
issuance of APIs shall be deemed to be received, for purposes of determining
Available Cash and Cash from Operations, during the quarter in respect of which
such APIs are issued, even if such APIs are actually issued and cash is received
by the Partnership after the last day of such quarter; and (ii) disbursements
(including, without limitation, contributions to the Operating Partnership or
disbursements on behalf of the Operating Partnership) made or reserves
established after the end of any quarter shall be deemed to have been made or
established, for purposes of determining Available Cash and Cash from
Operations, within such quarter if the General Partner so determines.
Notwithstanding the foregoing, in the event of the dissolution and liquidation
of the Partnership, all
 
                                      D-30
<PAGE>
proceeds of such liquidation shall be applied and distributed in accordance
with, and subject to the terms and conditions of such Sections 14.3 and 14.4.
 
    (c) At such time as the balance of Unrecovered API Capital in respect of any
Outstanding API is reduced to zero, such API shall be deemed to be redeemed and
shall thereupon cease to be Outstanding.
 
    5.4  DISTRIBUTIONS OF CASH FROM OPERATIONS.  Available Cash with respect to
any calendar quarter that is deemed to be Cash from Operations pursuant to the
provisions of Section 5.3 or 5.5 shall be distributed as follows, except as
otherwise required by the Omnibus Agreement, Section 13.4 in respect of the
redemption of APIs or Section 4.4(b):
 
        (a) FIRST, 99% to the Limited Partners, in accordance with their
    respective Percentage Interests, and 1% to the General Partner until there
    has been distributed in respect of each Common Unit Outstanding as of the
    last day of such quarter an amount equal to the Minimum Quarterly
    Distribution;
 
        (b) SECOND, 99% to the Limited Partners, in accordance with their
    respective Percentage Interests, and 1% to the General Partner until there
    has been distributed in respect of each Common Unit Outstanding as of the
    last day of such quarter an amount equal to the Cumulative Common Unit
    Arrearage, if any, existing with respect to such quarter;
 
        (c) THIRD, 100% to the Special Limited Partners, in proportion to the
    Unrecovered API Capital balance attributable to the respective APIs held by
    them, to the extent necessary to reduce to zero the Unrecovered API Capital
    balance, if any, of any and all APIs Outstanding as of the last day of such
    quarter;
 
        (d) FOURTH, 99% to all Limited Partners, in accordance with their
    respective Percentage Interests, and 1% to the General Partner until there
    has been distributed in respect of each Common Unit Outstanding as of the
    last day of such quarter an amount equal to the excess of the First Target
    Distribution over the Minimum Quarterly Distribution;
 
        (e) FIFTH, 85.8673% to all Limited Partners, in accordance with their
    respective Percentage Interests, and 14.1327% to the General Partner until
    there has been distributed in respect of each Common Unit Outstanding as of
    the last day of such quarter an amount equal to the excess of the Second
    Target Distribution over the First Target Distribution:
 
        (f) SIXTH, 75.7653% to all Limited Partners, in accordance with their
    respective Percentage Interests, and 24.2347% to the General Partner until
    there has been distributed in respect of each Common Unit Outstanding as of
    the last day of such quarter an amount equal to the excess of the Third
    Target Distribution over the Second Target Distribution; and
 
        (g) THEREAFTER, 50.5102% to all Limited Partners, in accordance with
    their respective Percentage Interests, and 49.4898% to the General Partner;
 
PROVIDED, HOWEVER, if the Minimum Quarterly Distribution, the First Target
Distribution, the Second Target Distribution and the Third Target Distribution
have been reduced to zero pursuant to the second sentence of Section 5.6, the
distributions of Available Cash that is deemed to be Cash from Operations with
respect to any quarter will be made 99% to the Limited Partners, in accordance
with their respective Percentage Interests, and 1% to the General Partner until
there has been distributed in respect of each Common Unit then Outstanding an
amount of Available Cash constituting Cash from Operations equal to the
Cumulative Common Unit Arrearage, if any, as of the last day of the most
recently completed quarter, and thereafter in accordance with Section 5.4(g).
 
    5.5  DISTRIBUTIONS OF CASH FROM INTERIM CAPITAL TRANSACTIONS.  Available
Cash that constitutes Cash from Interim Capital Transactions shall be
distributed, unless the provisions of Section 5.3 require otherwise, 99% to all
Limited Partners, in accordance with their respective Percentage Interests, and
1% to the General Partner until a hypothetical holder of a Common Unit acquired
on the Closing Date has received
 
                                      D-31
<PAGE>
with respect to such Common Unit, during the period since the Closing Date
through such date, distributions of Available Cash that are deemed to be Cash
from Interim Capital Transactions in an aggregate amount equal to the Initial
Unit Price. Thereafter, all Available Cash shall be distributed as if it were
Cash from Operations and shall be distributed in accordance with Section 5.4.
 
    5.6  ADJUSTMENT OF MINIMUM QUARTERLY DISTRIBUTION AND TARGET DISTRIBUTION
LEVELS.  (a) The Minimum Quarterly Distribution, First Target Distribution,
Second Target Distribution and Third Target Distribution shall be
proportionately adjusted in the event of any distribution, combination or
subdivision (whether effected by a distribution payable in Units or otherwise)
of Units or other Partnership Securities in accordance with Section 4.11. In the
event of a distribution of Available Cash that is deemed to be Cash from Interim
Capital Transactions, the Minimum Quarterly Distribution, First Target
Distribution, Second Target Distribution and Third Target Distribution shall be
adjusted proportionately downward to equal the product obtained by multiplying
the otherwise applicable Minimum Quarterly Distribution, First Target
Distribution, Second Target Distribution and Third Target Distribution, as the
case may be, by a fraction of which the numerator is the Unrecovered Initial
Unit Price of the Common Units immediately after giving effect to such
distribution and of which the denominator is the Unrecovered Initial Unit Price
of the Common Units immediately prior to giving effect to such distribution.
 
    (b) The Minimum Quarterly Distribution, First Target Distribution, Second
Target Distribution and Third Target Distribution shall also be subject to
adjustment pursuant to Section 9.6.
 
    5.7  SPECIAL PROVISIONS RELATING TO THE DEFERRED PARTICIPATION UNITS.  (a)
Except as otherwise provided in this Section 5.7, notwithstanding anything to
the contrary set forth in this Agreement, the holder of a Deferred Participation
Unit shall have the following rights and obligations:
 
        (i) prior to the end of the Deferral Period, the holder of a Deferred
    Participation Unit shall not be entitled to any distributions (other than
    distributions to Partners pursuant to Sections 14.3 and 14.4), shall not be
    allocated items of income, gain, loss or deduction other than allocations of
    such items to Partners holding Deferred Participation Units as specified in
    this Article V, shall not be entitled to vote on any matters requiring the
    approval or vote of the holders of Outstanding Units and shall possess the
    rights and obligations provided in this Agreement with respect to both (A) a
    Partner holding a Deferred Participation Unit and (B) a Limited Partner
    pursuant to Articles VI and VII (and, except as set forth in clauses (A) and
    (B) preceding, no other rights otherwise available to a holder of a
    Partnership Interest); and
 
        (ii) after the end of the Deferral Period, but prior to the conversion
    of Deferred Participation Units into Common Units pursuant to Section 5.7(c)
    (but in no event before the first day following the end of the Deferral
    Period), the holder of a Deferred Participation Unit will possess all of the
    rights and obligations of a Limited Partner, shall be entitled to
    participate in all allocations of income or loss and distributions made with
    respect to Common Units pursuant to this Agreement (except for Sections
    5.1(c)(i)(D) and 5.4(b) and the proviso at the end of Section 5.4 (other
    than the phrase "thereafter in accordance with Section 5.4(g)")) and all
    references to Common Units throughout this Agreement (excluding Article V)
    shall be interpreted to include Deferred Participation Units; PROVIDED,
    HOWEVER, such Deferred Participation Units shall (i) remain subject to the
    provisions of Section 4.6(c)(ii), 5.1(a)(ii), 5.1(d)(x) and 11.7 and (ii)
    not, until the Arrearage Elimination Date, be entitled to receive
    distributions pursuant to Section 5.4 in respect of any calendar quarter in
    excess of an amount per Deferred Participation Unit equal to the Minimum
    Quarterly Distribution.
 
    (b) Notwithstanding any other provision of this Agreement, if KMGP (or any
Affiliate of KMGP that is a successor to KMGP) is removed as general partner of
the Partnership under circumstances where Cause does not exist, the holder of a
Deferred Participation Unit will possess all of the rights and obligations of a
Limited Partner, shall be entitled to participate in all allocations of income
or loss and distributions of cash made with respect to Common Units pursuant to
this Article V and all references to
 
                                      D-32
<PAGE>
Units and Common Units throughout this Agreement shall be interpreted to include
Deferred Participation Units; PROVIDED, HOWEVER, such Deferred Participation
Units shall remain subject to the provisions of Sections 4.6(c)(ii), 5.1(a)(ii),
5.1(d)(x) and 11.7.
 
    (c) After the first to occur of the Arrearage Elimination Date or removal as
described in Section 5.7(b), once the General Partner determines, based on
advice of counsel, that a Deferred Participation Unit has, as a substantive
matter, like intrinsic economic and federal income tax characteristics, in all
material respects, to the intrinsic economic and federal income tax
characteristics of a Common Unit then Outstanding,then the Deferred
Participation Unit shall be converted to a Common Unit (on a one-for-one basis)
and from that time forward (which time shall in no event commence before the
first day following the end of the Deferral Period if the Arrearage Elimination
Date is the said first to occur) shall constitute a Common Unit for all purposes
under this Agreement. In connection with the condition set forth above, it is
understood that the General Partner may take whatever reasonable steps are
required to provide economic uniformity to the Deferred Participation Units in
preparation for a conversion into Common Units, including the application of
Sections 4.6(c) and 5.1(d)(x); PROVIDED, HOWEVER, that no such steps may be
taken that would have a material adverse effect on the Limited Partners or the
Record Holders of any class of Units.
 
    5.8  SPECIAL PROVISIONS RELATING TO HOLDERS OF APIS.  Notwithstanding
anything to the contrary set forth in this Agreement, the holder of an API (a)
shall (i) posses the rights and obligations provided in this Agreement with
respect to a Limited Partner pursuant to Articles VI and VII and (ii) have a
Capital Account as a Partner pursuant to Section 4.6 and all other provisions
related thereto and (b) shall not (i) be entitled to vote on any matters
requiring the approval or vote of the holders of Outstanding Units, (ii) be
entitled to any distributions other than to Partners pursuant to Sections 14.3
and 14.4 or in redemption of such APIs in accordance with the terms set forth in
this Agreement or in Article II of Part B of the Omnibus Agreement or (iii) be
allocated items of income, gain, loss or deduction other than as specified in
this Article V.

authorized to execute, deliver and perform the agreements referred to in clause
(i) of this sentence and the other agreements, acts, transactions and matters
described in the Registration Statement on behalf of the Partnership without any
further act, approval or vote of the Partners or the Assignees or the other
Persons who may acquire an interest in Units; and (iii) agrees that none of the
execution, delivery or performance by the General Partner, the Partnership, the
Operating Partnership or any Affiliate of any of them of this Agreement or any
agreement authorized or permitted under this Agreement (including, without
limitation, the exercise by the General Partner or any Affiliate of the General
Partner of the rights accorded pursuant to Article XVII) shall constitute a
breach by the General Partner of any duty that the General Partner may owe the
Partnership or the Limited Partners or the Assignees or any other Persons under
this Agreement or of any duty stated or implied by law or equity.

    6.2  CERTIFICATE OF LIMITED PARTNERSHIP.  The General Partner has caused the
Certificate of Limited Partnership to be filed with the Secretary of State of
the State of Delaware as required by the Delaware Act and shall use all
reasonable efforts to cause to be filed such other certificates or documents as
may be determined by the General Partner in its sole discretion to be reasonable
and necessary or appropriate for the formation, continuation, qualification and
operation of a limited partnership (or a partnership in which the limited
partners have limited liability) in the State of Delaware or any other state in
which the Partnership may elect to do business or own property. To the extent
that such action is determined by the General Partner in its sole discretion to
be reasonable and necessary or appropriate, the General Partner shall file
amendments to and restatements of the Certificate of Limited Partnership and do
all things to maintain the Partnership as a limited partnership (or a
partnership in which the limited partners have limited liability) under the laws
of the State of Delaware or of any other state in which the Partnership may
elect to do business or own property. Subject to the terms of Section 7.5(a),
the General Partner shall not be required, before or after filing, to deliver or
mail a copy of the Certificate of Limited Partnership, any qualification
document or any amendment thereto to any Limited Partner or Assignee.
 
    6.3  RESTRICTIONS ON GENERAL PARTNER'S AUTHORITY.  (a) The General Partner
may not, without written approval of the specific act by all of the Outstanding
Units or by other written instrument executed and delivered by all of the
Outstanding Units subsequent to the date of this Agreement, take any action in
contravention of this Agreement, including, without limitation, (i) any act that
would make it impossible to carry on the ordinary business of the Partnership,
except as otherwise provided in this Agreement; (ii) possess Partnership
property, or assign any rights in specific Partnership property, for other than
a Partnership purpose; (iii) admit a Person as a Partner, except as otherwise
provided in this Agreement; (iv) amend this Agreement in any manner, except as
otherwise provided in this Agreement; or (v) transfer its interest as general
partner of the Partnership, except as otherwise provided in this Agreement.
 
    (b) Except as provided in Article XIV and XVI, the General Partner may not
sell, exchange or otherwise dispose of all or substantially all of the
Partnership's assets in a single transaction or a series of related transactions
or approve on behalf of the Partnership the sale, exchange or other disposition
of all or substantially all of the assets of OLP-A, without the approval of at
least two-thirds of the Outstanding Units during the Support Period and
thereafter without the approval of at least a majority of the Outstanding Units;
PROVIDED, HOWEVER, that this provision shall not preclude or limit the General
Partner's ability to mortgage, pledge, hypothecate or grant a security interest
in all or substantially all of the Partnership's assets and shall not apply to
any forced sale of any or all of the Partnership's assets pursuant to the
foreclosure of, or other realization upon, any such encumbrance. Without the
approval of at least two-thirds of the Outstanding Units, the General Partner
shall not, on behalf of the Partnership, (i) consent to any amendment to the
OLP-A Partnership Agreement or, except as expressly permitted by Section 6.9(d),
take any action permitted to be taken by a partner of OLP-A, in either case,
that would adversely affect the Partnership as a partner of OLP-A or (ii) except
as permitted under Section 11.2 and 13.1, elect or cause the Partnership to
elect a successor general partner of OLP-A.
 
    (c) Unless approved by the affirmative vote of at least a majority of each
class of Outstanding Units, including a majority of Common Units (excluding for
purposes of such determination Common Units owned by the General Partner and its
Affiliates), the General Partner shall not take any action or refuse to take any
reasonable action the effect of which, if taken or not taken, as the case may
be, would be to cause the Partnership or the Operating Partnership to be treated
as an association taxable as a corporation or otherwise to be taxed as an entity
for federal income tax purposes; provided that this Section 6.3(c) shall not be
construed to apply to amendments to this Agreement (which are governed by
Article XV) or mergers or consolidations of the Partnership with any Person
(which are governed by Article XVI).
 
    (d) At all times while serving as the general partner of the Partnership,
the General Partner shall not make any dividend or distribution on, or
repurchase any shares of, its stock or take any other action within its control
if the effect of such dividend, distribution, repurchase or other action would
be to reduce its net
 
                                      D-35
<PAGE>
worth below an amount necessary to receive an Opinion of Counsel that the
Partnership will be treated as a partnership for federal income tax purposes.
 
    6.4  REIMBURSEMENT OF THE GENERAL PARTNER.  (a) Except as provided in this
Section 6.4 and elsewhere in this Agreement or in the Operating Partnership
Agreement, the General Partner shall not be compensated for its services as
general partner of the Partnership or the Operating Partnership.
 
    (b) The General Partner shall be reimbursed on a monthly basis, or such
other basis as the General Partner may determine in its sole discretion, for (i)
all direct and indirect expenses it incurs or payments it makes on behalf of the
Partnership (including, without limitation, amounts paid to any Person to
perform services for the Partnership or for the General Partner in the discharge
of its duties to the Partnership), and (ii) all other necessary or appropriate
expenses allocable to the Partnership or otherwise reasonably incurred by the
General Partner in connection with operating the Partnership's business
(including, without limitation, expenses allocated to the General Partner by its
Affiliates); PROVIDED, HOWEVER, that the General Partner shall not perform or be
reimbursed for the "Services" to be performed on behalf of the Partnership by
Enron and its Affiliates pursuant to the Omnibus Agreement. The General Partner
shall determine the fees and expenses that are allocable to the Partnership in
any reasonable manner determined by the General Partner in its sole discretion.
Reimbursements pursuant to this Section 6.4 shall be in addition to any
reimbursement to the General Partner as a result of indemnification pursuant to
Section 6.7.
 
    (c) Subject to Section 4.4(c), the General Partner in its sole discretion
and without the approval of the Limited Partners may propose and adopt on behalf
of the Partnership employee benefit plans (including, without limitation, plans
involving the issuance of Units), for the benefit of employees of the General
Partner, the Partnership, the Operating Partnership or any Affiliate of any of
them in respect of services performed, directly or indirectly, for the benefit
of the Partnership or the Operating Partnership.
 
    6.5  OUTSIDE ACTIVITIES.  (a) After the Closing Date, the General Partner,
for so long as it is the general partner of the Partnership, (i) agrees that its
sole business will be to act as the general partner of the Partnership and the
Operating Partnership and to undertake activities that are ancillary or related
thereto, and (ii) shall not enter into or conduct any business or incur any
debts or liabilities except in connection with or incidental to (A) its
performance of the activities required or authorized by the Operating
Partnership Agreement, this Agreement or the Omnibus Agreement or described in
or contemplated by the Registration Statement and (B) the acquisition, ownership
or disposition of partnership interests in the Partnership and the Operating
Partnership, except that, notwithstanding the foregoing, the General Partner may
also operate a natural gas liquids pipeline owned by Enron or any Affiliate
thereof and undertake activities that are ancillary or related thereto, and
employees of the General Partner may perform services for Enron and its
Affiliates.
 
    (b) Except as described in the Registration Statement, the Omnibus Agreement
or Section 6.5(a), no Indemnitee shall be expressly or implicitly restricted or
proscribed pursuant to this Agreement, the Operating Partnership Agreement or
the partnership relationship established hereby or thereby from engaging in
other activities for profit, whether in the businesses engaged in by the
Partnership or the Operating Partnership or anticipated to be engaged in by the
Partnership, the Operating Partnership or otherwise, including, without
limitation, those businesses described in or contemplated by the Registration
Statement. Without limitation of and subject to the foregoing (but subject to
the limitations set forth in the Omnibus Agreement), each Indemnitee shall have
the right to engage in the transportation of natural gas liquids and in other
businesses of every type and description and to engage in and possess an
interest in other business ventures of any and every type or description,
independently or with others, including, without limitation, business interests
and activities in direct competition with the Partnership or the Operating
Partnership, and none of the same shall breach any duty to the Partnership, the
Operating Partnership or any Partners. Neither the Partnership, the Operating
Partnership, any Limited Partner nor any other Person shall have any rights by
virtue of this Agreement, the Operating Partnership Agreement
 
                                      D-36
<PAGE>
or the partnership relationship established hereby or thereby in any business
ventures of any Indemnitee and, except as set forth in the Omnibus Agreement,
such Indemnitees shall have no obligation to offer any interest in any such
business ventures to the Partnership, the Operating Partnership, any Limited
Partner or any other Person. The General Partner and any other Persons
affiliated with the General Partner may acquire Units or other Partnership
Securities, in addition to those acquired by any of such Persons on the Closing
Date, and shall be entitled to exercise all rights of an Assignee or Limited
Partner, as applicable, relating to such Units or Partnership Securities, as the
case may be.
 
    (c) Without limitation of Section 6.5(a) and 6.5(b), and notwithstanding
anything to the contrary in this Agreement, the competitive activities of
certain Indemnitees and the restrictions on the Partnership's activities
described in the Registration Statement and in the Omnibus Agreement are hereby
approved by all Partners, and it shall not be deemed to be a breach of the
General Partner's fiduciary duty for the General Partner to permit an Indemnitee
to engage in a business opportunity in preference to or to the exclusion of the
Partnership, if such activities are permitted by this Agreement, the Operating
Partnership Agreement or the Omnibus Agreement.
 
    6.6  LOANS TO AND FROM THE GENERAL PARTNER; CONTRACTS WITH
AFFILIATES.  (a)(i) The General Partner of any Affiliate thereof may lend to the
Partnership or the Operating Partnership, and the Partnership and the Operating
Partnership may borrow, funds needed or desired by the Partnership and the
Operating Partnership for such periods of time as the General Partner may
determine and (ii) the General Partner or any Affiliate thereof may borrow from
the Partnership or the Operating Partnership, and the Partnership and the
Operating Partnership may lend to the General Partner or such Affiliate, excess
funds of the Partnership and the Operating Partnership for such periods of time
and in such amounts as the General Partner may determine; PROVIDED, HOWEVER,
that in either such case the lending party may not charge the borrowing party
interest at a rate greater than the rate that would be charged the borrowing
party (without reference to the leading party's financial abilities or
guarantees), by unrelated lenders on comparable loans. The borrowing party shall
reimburse the lending party for any costs (other than any additional interest
costs) incurred by the lending party in connection with the borrowing of such
funds. For purposes of this Section 6.6(a) and Section 6.6(b), the term
"Partnership" shall include any Affiliate of the Partnership that is controlled
by the Partnership and the term "Operating Partnership" shall include any
Affiliate of the Operating Partnership that is controlled by the Operating
Partnership.
 
    (b) The Partnership may lend or contribute to the Operating Partnership, and
the Operating Partnership may borrow, funds on terms and conditions established
in the sole discretion of the General Partner; PROVIDED, HOWEVER, that the
Partnership may not charge the Operating Partnership interest at a rate greater
than the rate that would be charged to the Operating Partnership (without
reference to the General Partner's financial abilities or guarantees), by
unrelated lenders on comparable loans. The foregoing authority shall be
exercised by the General Partner in its sole discretion and shall not create any
right or benefit in favor of the Operating Partnership or any other Persons.
 
    (c) The General Partner may itself, or may enter into an agreement, in
addition to the Omnibus Agreement, with any of its Affiliates to, render
services to the Partnership or to the General Partner in the discharge of its
duties as general partner of the Partnership. Any service rendered to the
Partnership by the General Partner or any of its Affiliates shall be on terms
that are fair and reasonable to the Partnership; PROVIDED, HOWEVER, that the
requirements of this Section 6.6(c) shall be deemed satisfied as to (i) any
transaction approved by Special Approval, (ii) any transaction, the terms of
which are no less favorable to the Partnership than those generally being
provided to or available from unrelated third parties, or (iii) any transaction
that, taking into account the totality of the relationships between the parties
involved (including other transactions that may be particularly favorable or
advantageous to the Partnership), is equitable to the Partnership. The
provisions of Section 6.4 shall apply to the rendering of services described in
this Section 6.6(c).
 
                                      D-37
<PAGE>
    (d) The Partnership may transfer assets to joint ventures, other
partnerships, corporations or other business entities in which it is or thereby
becomes a participant upon such terms and subject to such conditions as are
consistent with this Agreement and applicable law.
 
    (e) Neither the General Partner nor any of its Affiliates shall sell,
transfer or convey any property to, or purchase any property from, the
Partnership, directly or indirectly, except pursuant to transactions that are
fair and reasonable to the Partnership; PROVIDED, HOWEVER, that the requirements
of this Section 6.6(e) shall be deemed to be satisfied as to (i) the
transactions effected pursuant to Sections 4.2 and 4.3, the Conveyance
Agreement, the Mortgage and any other transactions described in or contemplated
by the Registration Statement, (ii) any transaction approved by Special
Approval, (iii) any transaction, the terms of which are no less favorable to the
Partnership than those generally being provided to or available from unrelated
third parties, or (iv) any transaction that, taking into account the totality of
the relationships between the parties involved (including other transactions
that may be particularly favorable or advantageous to the Partnership), is
equitable to the Partnership.
 
    (f) The General Partner and its Affiliates will have no obligation to permit
the Partnership or the Operating Partnership to use any facilities or assets of
the General Partner and its Affiliates, except as may be provided in contracts
entered into from time to time specifically dealing with such use, nor shall
there be any obligation on the General Partner or its Affiliates to enter into
such contracts.
 
    (g) Without limitation of Sections 6.6(a) through 6.6(f), and
notwithstanding anything to the contrary in this Agreement, the existence of the
conflicts of interest described in the Registration Statement and in the Omnibus
Agreement are hereby approved by all Partners.
 
    6.7  INDEMNIFICATION.  (a) To the fullest extent permitted by law but
subject to the limitations expressly provided in this Agreement, the General
Partner, any Departing Partner and any Person who is or was an officer or
director of the General Partner or any Departing Partner shall be indemnified
and held harmless by the Partnership, and all other Indemnitees may be
indemnified and held harmless by the Partnership, to the extent deemed advisable
by the General Partner, from and against any and all losses, claims, damages,
liabilities, joint or several, expenses (including, without limitation, legal
fees and expenses), judgments, fines, penalties, interest, settlements and other
amounts arising from any and all claims, demands, actions, suits or proceedings,
whether civil, criminal, administrative or investigative, in which any
Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, by reason of its status as (i) the General Partner, a Departing
Partner or any of their Affiliates, (ii) an officer, director, employee,
partner, agent or trustee of the General Partner, any Departing Partner or any
of their Affiliates or (iii) a Person serving at the request of the Partnership
in another entity in a similar capacity, PROVIDED, that in each case the
Indemnitee acted in good faith and in the manner which such Indemnitee believed
to be in, or not opposed to, the best interests of the Partnership, and, with
respect to any criminal proceeding, had no reasonable cause to believe its
conduct was unlawful; PROVIDED, FURTHER, no indemnification pursuant to this
Section 6.7 shall be available to the General Partner with respect to its
obligations incurred pursuant to the Underwriting Agreement or the Conveyance
Agreement (other than obligations incurred by the General Partner on behalf of
the Partnership or the Operating Partnership). The termination of any action,
suit or proceeding by judgment, order, settlement, conviction or upon a plea of
nolo contendere, or its equivalent, shall not create a presumption that the
Indemnitee acted in a manner contrary to that specified above. Any
indemnification pursuant to this Section 6.7 shall be made only out of the
assets of the Partnership, it being agreed that the General Partner shall not be
personally liable for such indemnification and shall have no obligation to
contribute or loan any monies or property to the Partnership to enable it to
effectuate such indemnification.
 
                                      D-38
<PAGE>
    (b) To the fullest extent permitted by law, expenses (including, without
limitation, legal fees and expenses) incurred by an Indemnitee who is
indemnified pursuant to Section 6.7(a) in defending any claim, demand, action,
suit or proceeding shall, from time to time, be advanced by the Partnership
prior to the final disposition of such claim, demand, action, suit or proceeding
upon receipt by the Partnership of an undertaking by or on behalf of the
Indemnitee to repay such amount if it shall be determined that the Indemnitee is
not entitled to be indemnified as authorized in this Section 6.7.
 
    (c) The indemnification provided by this Section 6.7 shall be in addition to
any other rights to which an Indemnitee may be entitled under any agreement,
pursuant to any vote of the holders of Outstanding Units, as a matter of law or
otherwise, both as to actions in the Indemnitee's capacity as (i) the General
Partner, a Departing Partner or an Affiliate thereof, (ii) an officer, director,
employee, partner, agent or trustee of the General Partner, any Departing
Partner or an Affiliate thereof or (iii) a Person serving at the request of the
Partnership in another entity in a similar capacity, and as to actions in any
other capacity (including, without limitation, any capacity under the
Underwriting Agreement), and shall continue as to an Indemnitee who has ceased
to serve in such capacity and shall inure to the benefit of the heirs,
successors, assigns and administrators of the Indemnitee.
 
    (d) The Partnership may purchase and maintain (or reimburse the General
Partner or its Affiliates for the cost of) insurance, on behalf of the General
Partner and such other Persons as the General Partner shall determine, against
any liability that may be asserted against or expense that may be incurred by
such Person in connection with the Partnership's activities, regardless of
whether the Partnership would have the power to indemnify such Person against
such liability under the provisions of this Agreement.
 
    (e) For purposes of this Section 6.7, the Partnership shall be deemed to
have requested an Indemnitee to serve as fiduciary of an employee benefit plan
whenever the performance by it of its duties to the Partnership also imposes
duties on, or otherwise involves services by, it to the plan or participants or
beneficiaries of the plan; excise taxes assessed on an Indemnitee with respect
to an employee benefit plan pursuant to applicable law shall constitute "fines"
within the meaning of Section 6.7(a); and action taken or omitted by it with
respect to an employee benefit plan in the performance of its duties for a
purpose reasonably believed by it to be in the interest of the participants and
beneficiaries of the plan shall be deemed to be for a purpose which is in, or
not opposed to, the best interests of the Partnership.
 
    (f) In no event may an Indemnitee subject the Limited Partners to personal
liability by reason of the indemnification provisions set forth in this
Agreement.
 
    (g) An Indemnitee shall not be denied indemnification in whole or in part
under this Section 6.7 because the Indemnitee had an interest in the transaction
with respect to which the indemnification applies if the transaction was
otherwise permitted by the terms of this Agreement or the Omnibus Agreement.
 
    (h) The provisions of this Section 6.7 are for the benefit of the
Indemnities, their heirs, successors, assigns and administrators and shall not
be deemed to create any rights for the benefit of any other Persons.
 
    (i) No amendment, modification or repeal of this Section 6.7 or any
provision hereof shall in any manner terminate, reduce or impair the right of
any past, present or future Indemnitee to be indemnified by the Partnership, nor
the obligation of the Partnership to indemnify any such Indemnitee under and in
accordance with the provisions of this Section 6.7 as in effect immediately
prior to such amendment, modification or repeal with respect to claims arising
from or relating to matters occurring, in whole or in part, prior to such
amendment, modification or repeal, regardless of when such claims may arise or
be asserted.
 
    6.8  LIABILITY OF INDEMNITEES.  (a) Notwithstanding anything to the contrary
set forth in this Agreement, no Indemnitee shall be liable for monetary damages
to the Partnership, the Limited Partners, the Assignees or any other Persons who
have acquired interests in the Units, for losses sustained or liabilities
incurred as a result of any act or omission if such Indemnitee acted in good
faith.
 
                                      D-39
<PAGE>
    (b) Subject to its obligations and duties as General Partner set forth in
Section 6.1(a), the General Partner may exercise any of the powers granted to it
by this Agreement and perform any of the duties imposed upon it hereunder either
directly or by or through its agents, and the General Partner shall not be
responsible for any misconduct or negligence on the part of any such agent
appointed by the General Partner in good faith.
 
    (c) Any amendment, modification or repeal of this Section 6.8 or any
provision hereof shall be prospective only and shall not in any way affect the
limitations on the liability to the Partnership and the Limited Partners of the
General Partner, its directors, officers and employees under this Section 6.8 as
in effect immediately prior to such amendment, modification or repeal with
respect to claims arising from or relating to matters occurring, in whole or in
part, prior to such amendment, modification or repeal, regardless of when such
claims may arise or be asserted.
 
    6.9  RESOLUTION OF CONFLICTS OF INTEREST.  (a) Unless otherwise expressly
provided in this Agreement, the Operating Partnership Agreement or the Omnibus
Agreement, whenever a potential conflict of interest exists or arises between
the General Partner or any of its Affiliates, on the one hand, and the
Partnership, the Operating Partnership, and Partner or any Assignee, on the
other hand, any resolution or course of action in respect of such conflict of
interest shall be permitted and deemed approved by all Partners, and shall not
constitute a breach of this Agreement, of the Operating Partnership Agreement,
of any agreement contemplated herein or therein, or of any duty stated or
implied by law or equity, if the resolution or course of action is or, by
operation of this Agreement is deemed to be, fair and reasonable to the
Partnership. The General Partner shall be authorized but not required in
connection with its resolution of such conflict of interest to seek Special
Approval of a resolution of such conflict or course of action. Any conflict of
interest and any resolution of such conflict of interest shall be conclusively
deemed fair and reasonable to the Partnership if such conflict of interest or
resolution is (i) approved by Special Approval, (ii) on terms no less favorable
to the Partnership than those generally being provided to or available from
unrelated third parties or (iii) fair to the Partnership, taking into account
the totality of the relationships between the parties involved (including other
transactions that may be particularly favorable or advantageous to the
Partnership). The General Partner may also adopt a resolution or course of
action that has not received Special Approval. The General Partner (including
the Conflicts and Audit Committee in connection with Special Approval) shall be
authorized in connection with its determination of what is "fair and reasonable"
to the Partnership and in connection with its resolution of any conflict of
interest to consider (A) the relative interests of any party to such conflict,
agreement, transaction or situation and the benefits and burdens relating to
such interest; (B) any customary or accepted industry practices and any
customary or historical dealings with a particular Person; (C) any applicable
generally accepted accounting or engineering practices or principles; and (D)
such additional factors as the General Partner (including such Conflicts and
Audit Committee) determines in its sole discretion to be relevant, reasonable or
appropriate under the circumstances. Nothing contained in this Agreement,
however, is intended to nor shall it be construed to require the General Partner
(including such Conflicts and Audit Committee) to consider the interest of any
Person other than the Partnership. In the absence of bad faith by the General
Partner, the resolution, action or terms so made, taken or provided by the
General Partner with respect to such matter shall not constitute a breach of
this Agreement or any other agreement contemplated herein or a breach of any
standard of care or duty imposed herein or therein or under the Delaware Act or
any other law, rule or regulation.
 
    (b) Whenever this Agreement or any other agreement contemplated hereby
provides that the General Partner or any of its Affiliates is permitted or
required to make a decision (i) in its "sole discretion" or "discretion," that
it deems "necessary or appropriate" or under a grant of similar authority or
latitude, the General Partner or such Affiliate shall be entitled to consider
only such interests and factors as it desires and shall have no duty or
obligation to give any consideration to any interest of, or factors affecting,
the Partnership, the Operating Partnership, any Limited Partner or any Assignee,
(ii) it may make such decision in its sole discretion (regardless of whether
there is a reference to "sole
 
                                      D-40
<PAGE>
discretion" or "discretion") unless another express standard is provided for, or
(iii) in "good faith" or under another express standard, the General Partner or
such Affiliate shall act under such express standard and shall not be subject to
any other or different standards imposed by this Agreement, the Operating
Partnership Agreement, any other agreement contemplated hereby or under the
Delaware Act or any other law, rule or regulation. In addition, any actions
taken by the General Partner consistent with the standards of "reasonable
discretion" set forth in the definitions of Available Cash or Cash from
Operations shall not constitute a breach of any duty of the General Partner to
the Partnership or the Limited Partners. The General Partner shall have no duty,
express or implied, to sell or otherwise dispose of any asset of the Operating
Partnership or of the Partnership, other than in the ordinary course of
business. No borrowing by the Partnership or the Operating Partnership or the
approval thereof by the General Partner shall be deemed to constitute a breach
of any duty of the General Partner to the Partnership or the Limited Partners by
reason of the fact that the purpose or effect of such borrowing is directly or
indirectly to (A) enable the General Partner to receive or increase the amount
of Incentive Distributions, (B) reduce or eliminate the obligation of Enron or
any of its Affiliates to purchase APIs under the Omnibus Agreement, (C) permit
redemption of APIs, (D) shorten the Deferral Period or (E) reduce the Cumulative
Common Unit Arrearage in order to hasten the conversion of the Deferred
Participation Units into Common Units.
 
    (c) Whenever a particular transaction, arrangement or resolution of a
conflict of interest is required under this Agreement to be "fair and
reasonable" to any Person, the fair and reasonable nature of such transaction,
arrangement or resolution shall be considered in the context of all similar or
related transactions.
 
    (d) The Limited Partners hereby authorize the General Partner, on behalf of
the Partnership as a partner of the Operating Partnership, to approve of actions
by the general partner of the Operating Partnership similar to those actions
permitted to be taken by the General Partner pursuant to this Section 6.9.
 
    6.10  OTHER MATTERS CONCERNING THE GENERAL PARTNER.  (a) The General Partner
may rely and shall be protected in acting or refraining from acting upon any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order, bond, debenture, or other paper or document believed by
it to be genuine and to have been signed or presented by the proper party or
parties.
 
    (b) The General Partner may consult with legal counsel, accountants,
appraisers, management consultants, investment bankers and other consultants and
advisers selected by it, and any act taken or omitted to be taken in reliance
upon the opinion (including, without limitation, an Opinion of Counsel) of such
Persons as to matters that such General Partner reasonably believes to be within
such Person's professional or expert competence shall be conclusively presumed
to have been done or omitted in good faith and in accordance with such opinion.
 
    (c) The General Partner shall have the right, in respect of any of its
powers or obligations hereunder, to act through any of its duly authorized
officers and a duly appointed attorney or attorneys-in-fact. Each such attorney
shall, to the extent provided by the General Partner in the power of attorney,
have full power and authority to do and perform each and every act and duty that
is permitted or required to be done by the General Partner hereunder.
 
    (d) Any standard of care any duty imposed by this Agreement or under the
Delaware Act or any applicable law, rule or regulation shall be modified, waived
or limited as required to permit the General Partner to act under this Agreement
or any other agreement contemplated by this Agreement and to make any decision
pursuant to the authority prescribed in this Agreement so long as such action is
reasonably believed by the General Partner to be in, or not inconsistent with,
the best interests of the Partnership.
 
    6.11  TITLE TO PARTNERSHIP ASSETS.  Title to Partnership assets, whether
real, personal or mixed and whether tangible or intangible, shall be deemed to
be owned by the Partnership as an entity, and no
 
                                      D-41
<PAGE>
Partner or Assignee, individually or collectively, shall have any ownership
interest in such Partnership assets or any portion thereof. Title to any or all
of the Partnership assets may be held in the name of the Partnership, the
General Partner, one or more of its Affiliates or one or more nominees, as the
General Partner may determine. The General Partner hereby declares and warrants
that any Partnership assets for which record title is held in the name of the
General Partner or one or more of its Affiliates or one or more nominees shall
be held by the General Partner or such Affiliate or nominee for the use and
benefit of the Partnership in accordance with the provisions of this Agreement;
PROVIDED, HOWEVER, that the General Partner shall use its reasonable efforts to
cause record title to such assets (other than those assets in respect of which
the General Partner determines that the expense and difficulty of conveyancing
makes transfer of record title to the Partnership impracticable) to be vested in
the Partnership as soon as reasonably practicable; provided that, prior to the
withdrawal or removal of the General Partner or as soon thereafter as
practicable, the General Partner shall use reasonable efforts to effect the
transfer of record title to the Partnership and prior to any such transfer, will
provide for the use of such assets in a manner satisfactory to the Partnership.
All Partnership assets shall be recorded as the property of the Partnership in
its books and records, irrespective of the name in which record title to such
Partnership assets is held.
 
    6.12  PURCHASE OR SALE OF UNITS.  The General Partner may cause the
Partnership to purchase or otherwise acquire Units; provided that the General
Partner may not cause the Partnership to purchase Deferred Participation Units
during the Deferral Period. As long as Units are held by the Partnership or the
Operating Partnership, such Units shall not be considered Outstanding for any
purpose, except as otherwise provided herein. The General Partner or any
Affiliate of the General Partner may also purchase or otherwise acquire and sell
or otherwise dispose of Units for its own account, subject to the provisions of
Articles XI and XII.
 
    6.13  REGISTRATION RIGHTS OF KMGP AND ITS AFFILIATES.  (a) If (i) KMGP or
any Affiliate (including, without limitation, for purposes of this Section 6.13,
any Person that is an Affiliate at the date hereof notwithstanding that it may
later cease to be an Affiliate) holds Units or other Partnership Securities that
it desires to sell and (ii) Rule 144 of the Securities Act (or any successor
rule or regulation to Rule 144) or another exemption from registration is not
available to enable such holder of Units (the "HOLDER") to dispose of the number
of Units or other securities it desires to sell at the time it desires to do so
without registration under the Securities Act, then upon the request of KMGP or
any of its Affiliates, the Partnership shall file with the Securities and
Exchange Commission as promptly as practicable after receiving such request, and
use all reasonable efforts to cause to become effective and remain effective for
a period of not more than six months following its effective date, a
registration statement under the Securities Act registering the offering and
sale of the number of Units or other securities specified by the Holder;
PROVIDED, HOWEVER, that the Partnership shall not be required to effect more
than three registrations pursuant to this Section 6.13(a); and PROVIDED FURTHER,
that if the General Partner or, if at the time a request pursuant to this
Section 6.13 is submitted to the Partnership, KMGP or its Affiliate requesting
registration is an Affiliate of the General Partner, the Conflicts and Audit
Committee in connection with Special Approval determines in good faith judgment
that a postponement of the requested registration for up to six months would be
in the best interest of the Partnership and its Partners due to a pending
transaction, investigation or other event, the filing of such registration
statement or the effectiveness thereof may be deferred for up to six months, but
not thereafter. In connection with any registration pursuant to the immediately
preceding sentence, the Partnership shall promptly prepare and file (x) such
documents as may be necessary to register or qualify the securities subject to
such registration under the securities laws of such states as the Holder shall
reasonably request; PROVIDED, HOWEVER, that no such qualification shall be
required in any jurisdiction where, as a result thereof, the Partnership would
become subject to general service of process or to taxation or qualification to
do business as a foreign corporation or partnership doing business in such
jurisdiction, and (y) such documents as may be necessary to apply for listing or
to list the securities subject to such registration on such National Securities
Exchange as the Holder shall reasonably request, and do any and all other acts
and things that may reasonably be necessary or advisable to enable the Holder to
consummate a public sale of such Units in such states. Except as set forth in
 
                                      D-42
<PAGE>
Section 6.13(c), all costs and expenses of any such registration and offering
(other than the underwriting discounts and commissions) shall be paid by the
Partnership, without reimbursement by the Holder.
 
    (b) If the Partnership shall at any time propose to file a registration
statement under the Securities Act for an offering of equity securities of the
Partnership for cash (other than an offering relating solely to an employee
benefit plan), the Partnership shall use all reasonable efforts to include such
number or amount of securities held by the Holder in such registration statement
as the Holder shall request. If the proposed offering pursuant to this Section
6.13(b) shall be an underwritten offering, then, in the event that the managing
underwriter of such offering advises the Partnership and the Holder in writing
that in its opinion the inclusion of all or some of the Holder's securities
would adversely and materially affect the success of the offering, the
Partnership shall include in such offering only that number or amount, if any,
of securities held by the Holder which, in the opinion of the managing
underwriter, will not so adversely and materially affect the offering. Except as
set forth in Section 6.13(c), all costs and expenses of any such registration
and offering (other than the underwriting discounts and commissions) shall be
paid by the Partnership, without reimbursement by the Holder.
 
    (c) If underwriters are engaged in connection with any registration referred
to in this Section 6.13, the Partnership shall provide indemnification,
representations, covenants, opinions and other assurance to the underwriters in
form and substance reasonably satisfactory to such underwriters. Further, in
addition to and not in limitation of the Partnership's obligations under Section
6.7, the Partnership shall, to the fullest extent permitted by law, indemnify
and hold harmless the Holder, its officers, directors and each Person who
controls the Holder (within the meaning of the Securities Act) and any agent
thereof (collectively, "INDEMNIFIED PERSONS") against any losses, claims,
demands, actions, causes of action, assessments, damages, liabilities (joint or
several), costs and expenses (including, without limitation, interest, penalties
and reasonable attorneys' fees and disbursements), resulting to, imposed upon,
or incurred by the Indemnified Persons, directly or indirectly, under the
Securities Act or otherwise (hereinafter referred to in this Section 6.13(c) as
a "CLAIM" and in the plural as "CLAIMS"), based upon, arising out of, or
resulting from any untrue statement or alleged untrue statement of any material
fact contained in any registration statement under which any Units were
registered under the Securities Act or any state securities or Blue Sky laws, in
any preliminary prospectus (if used prior to the effective date of such
registration statement), or in any summary or final prospectus or in any
amendment or supplement thereof (if used during the period the Partnership is
required to keep the registration current), or arising out of, based upon or
resulting from the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements made therein
not misleading, PROVIDED, HOWEVER, that the Partnership shall not be liable to
any Indemnified Person to the extent that any such claim arises out of, is based
upon or results from an untrue statement or alleged untrue statement or omission
or alleged omission made in such registration statement, such preliminary,
summary or final prospectus or such amendment or supplement, in reliance upon
and in conformity with written information furnished to the Partnership by or on
behalf of such Indemnified Person specifically for use in the preparation
thereof.
 
    (d) The provisions of Sections 6.13(a) and 6.13(b) shall continue to be
applicable with respect to KMGP (and any of KMGP's Affiliates) after it ceases
to be a Partner of the Partnership, during a period of two years subsequent to
the effective date of such cessation and for so long thereafter as is required
for the Holder to sell all of the Units or other securities of the Partnership
with respect to which it has requested during such two-year period that a
registration statement be filed; PROVIDED, HOWEVER, that the Partnership shall
not be required to file successive registration statements covering the same
securities for which registration was demanded during such two-year period. The
provisions of Section 6.13(c) shall continue in effect thereafter.
 
    (e) Any request to register Partnership Securities pursuant to this Section
6.13 shall (i) specify the Partnership Securities intended to be offered and
sold by the Person making the request, (ii) express such Person's present intent
to offer such shares for distribution, (iii) describe the nature or method of
the proposed offer and sale of Partnership Securities, and (iv) contain the
undertaking of such Person to
 
                                      D-43
<PAGE>
provide all such information and material and take all action as may be required
in order to permit the Partnership to comply with all applicable requirements in
connection with the registration of such Partnership Securities.
 
    6.14  RELIANCE BY THIRD PARTIES.  Notwithstanding anything to the contrary
in this Agreement, any Person dealing with the Partnership shall be entitled to
assume that the General Partner has full power and authority to encumber, sell
or otherwise use in any manner any and all assets of the Partnership and to
enter into any contracts on behalf of the Partnership, and such Person shall be
entitled to deal with the General Partner as if it were the Partnership's sole
party in interest, both legally and beneficially. Each Limited Partner hereby
waives any and all defenses or other remedies that may be available against such
Person to contest, negate or disaffirm any action of the General Partner in
connection with any such dealing. In no event shall any Person dealing with the
General Partner or its representatives be obligated to ascertain that the terms
of this Agreement have been complied with or to inquire into the necessity or
expedience of any act or action of the General Partner or its representatives.
Each and every certificate, document or other instrument executed on behalf of
the Partnership by the General Partner or its representatives shall be
conclusive evidence in favor of any and every Person relying thereon or claiming
thereunder that (a) at the time of the execution and delivery of such
certificate, document or instrument, this Agreement was in full force and
effect, (b) the Person executing and delivering such certificate, document or
instrument was duly authorized and empowered to do so for and on behalf of the
Partnership and (c) such certificate, document or instrument was duly executed
and delivered in accordance with the terms and provisions of this Agreement and
is binding upon the Partnership.
 
                                  ARTICLE VII
                   RIGHTS AND OBLIGATIONS OF LIMITED PARTNERS
 
    7.1  LIMITATION OF LIABILITY.  The Limited Partners, the Organizational
Limited Partner and the Assignees shall have no liability under this Agreement
except as expressly provided in this Agreement or the Delaware Act.
 
    7.2  MANAGEMENT OF BUSINESS.  No Limited Partner or Assignee (other than the
General Partner, any of its Affiliates or any officer, director, employee,
partner, agent or trustee of the General Partner or any of its Affiliates, in
its capacity as such, if such Person shall also be a Limited Partner or
Assignee) shall participate in the operation, management or control (within the
meaning of the Delaware Act) of the Partnership's business, transact any
business in the Partnership's name or have the power to sign documents for or
otherwise bind the Partnership. The transaction of any such business by the
General Partner, any of its Affiliates or any officer, director, employee,
partner, agent or trustee of the General Partner or any of its Affiliates, in
its capacity as such, shall not affect, impair or eliminate the limitations on
the liability of the Limited Partners or Assignees under this Agreement.
 
    7.3  OUTSIDE ACTIVITIES.  Subject to the provisions of Section 6.5, which
shall continue to be applicable to the Persons referred to therein, regardless
of whether such Persons shall also be Limited Partners or Assignees, any Limited
Partner or Assignee shall be entitled to and may have business interests and
engage in business activities in addition to those relating to the Partnership,
including, without limitation, business interests and activities in direct
competition with the Partnership or the Operating Partnership. Neither the
Partnership nor any of the other Partners or Assignees shall have any rights by
virtue of this Agreement in any business ventures of any Limited Partner or
Assignee.
 
    7.4  RETURN OF CAPITAL.  No Limited Partner or Assignee shall be entitled to
the withdrawal or return of his Capital Contribution, except to the extent, if
any, that distributions made pursuant to this Agreement or upon termination of
the Partnership may be considered as such by law and then only to the extent
provided for in this Agreement. Except to the extent provided by Article V or as
otherwise expressly provided in this Agreement or in the Omnibus Agreement, no
Limited Partner or Assignee shall have
 
                                      D-44
<PAGE>
priority over any other Limited Partner or Assignee either as to the return of
Capital Contributions or as to profits, losses or distributions. Any such return
shall be a compromise to which all Partners and Assignees agree within the
meaning of Section 17-502(b) of the Delaware Act.
 
    7.5  RIGHTS OF LIMITED PARTNERS RELATING TO THE PARTNERSHIP.  (a) In
addition to other rights provided by this Agreement or by applicable law, and
except as limited by Section 7.5(b), each Limited Partner shall have the right,
for a purpose reasonably related to such Limited Partner's interest as a limited
partner in the Partnership, upon reasonable demand and at such Limited Partner's
own expense:
 
        (i) to obtain true and full information regarding the status of the
    business and financial condition of the Partnership;
 
        (ii) promptly after becoming available, to obtain a copy of the
    Partnership's federal, state and local tax returns for each year;
 
        (iii) to have furnished to him, upon notification to the General
    Partner, a current list of the name and last known business, residence or
    mailing address of each Partner;
 
        (iv) to have furnished to him, upon notification to the General Partner,
    a copy of this Agreement, the Omnibus Agreement and the Certificate of
    Limited Partnership and all amendments thereto, together with a copy of the
    executed copies of all powers of attorney pursuant to which this Agreement,
    the Certificate of Limited Partnership and all amendments thereto have been
    executed;
 
        (v) to obtain true and full information regarding the amount of cash and
    description and statement of the Agreed Value of any other Capital
    Contribution by each Partner and which each Partner has agreed to contribute
    in the future, and the date on which each became a Partner; and
 
        (vi) to obtain such other information regarding the affairs of the
    Partnership as is just and reasonable.
 
    (b) Notwithstanding any other provision of this Agreement, the General
Partner may keep confidential from the Limited Partners and Assignees, for such
period of time as the General Partner deems reasonable, any information that the
General Partner reasonably believes to be in the nature of trade secrets or
other information the disclosure of which the General Partner in good faith
believes is not in the best interests of the Partnership or the Operating
Partnership or could damage the Partnership or the Operating Partnership or that
the Partnership or the Operating Partnership is required by law or by agreements
with third parties to keep confidential (other than agreements with Affiliates
the primary purpose of which is to circumvent the obligations set forth in this
Section 7.5).
 
                                  ARTICLE VIII
                     BOOKS, RECORDS, ACCOUNTING AND REPORTS
 
    8.1  RECORDS AND ACCOUNTING.  The General Partner shall keep or cause to be
kept at the principal office of the Partnership appropriate books and records
with respect to the Partnership's business, including, without limitation, all
books and records necessary to provide to the Limited Partners any information,
lists and copies of documents required to be provided pursuant to Section
7.5(a). Any books and records maintained by or on behalf of the Partnership in
the regular course of its business, including, without limitation, the record of
the Record Holders and Assignees of Units or other Partnership Securities, books
of account and records of Partnership proceedings, may be kept on, or be in the
form of, punch cards, magnetic tape, photographs, micrographics or any other
information storage device, PROVIDED, that the books and records so maintained
are convertible into clearly legible written form within a reasonable period of
time. The books of the Partnership shall be maintained, for financial reporting
purposes, on an accrual basis in accordance with generally accepted accounting
principles.
 
    8.2  FISCAL YEAR.  The fiscal year of the Partnership shall be the calendar
year.
 
                                      D-45
<PAGE>
    8.3  REPORTS.  (a) As soon as practicable, but in no event later than 120
days after the close of each fiscal year of the Partnership, the General Partner
shall cause to be mailed to each Record Holder of a Unit as of a date selected
by the General Partner in its sole discretion, an annual report containing
financial statements of the Partnership for such fiscal year of the Partnership,
presented in accordance with generally accepted accounting principles, including
a balance sheet and statements of operations, Partners' equity and cash flows,
such statements to be audited by a firm of independent public accountants
selected by the General Partner.
 
    (b) As soon as practicable, but in no event later than 90 days after the
close of each calendar quarter except the last calendar quarter of each year,
the General Partner shall cause to be mailed to each Record Holder of a Unit, as
of a date selected by the General Partner in its sole discretion, a report
containing unaudited financial statements of the Partnership and such other
information as may be required by applicable law, regulation or rule of any
National Securities Exchange on which the Units are listed for trading, or as
the General Partner determines to be necessary or appropriate.
 
                                   ARTICLE IX
                                  TAX MATTERS
 
    9.1  PREPARATION OF TAX RETURNS.  The General Partner shall arrange for the
preparation and timely filing of all returns of Partnership income, gains,
deductions, losses and other items required of the Partnership for federal and
state income tax purposes and shall use all reasonable efforts to furnish,
within 90 days of the close of each taxable year of the Partnership, the tax
information reasonably required by holders of Outstanding Units for federal and
state income tax reporting purposes. The classification, realization and
recognition of income, gain, losses and deductions and other items shall be on
the accrual method of accounting for federal income tax purposes. The taxable
year of the Partnership shall be the calendar year.
 
    9.2  TAX ELECTIONS.  Except as otherwise provided herein, the General
Partner shall, in its sole discretion, determine whether to make any available
election pursuant to the Code; PROVIDED, HOWEVER, that the General Partner shall
make the election under Section 754 of the Code in accordance with applicable
regulations thereunder. The General Partner shall have the right to seek to
revoke any such election (including without limitation, the election under
Section 754 of the Code) upon the General Partner's determination in its sole
discretion that such revocation is in the best interests of the Limited Partners
and Assignees. For purposes of computing the adjustments under Section 743(b) of
the Code, the General Partner shall be authorized (but not required) to adopt a
convention whereby the price paid by a transferee of Units will be deemed to be
the lowest quoted trading price of the Units on any National Securities Exchange
on which such Units are traded during the calendar month in which such transfer
is deemed to occur pursuant to Section 5.2(g) without regard to the actual price
paid by such transferee.
 
    9.3  TAX CONTROVERSIES.  Subject to the provisions hereof, the General
Partner is designated the Tax Matters Partner (as defined in Section 6231 of the
Code), and is authorized and required to represent the Partnership (at the
Partnership's expense) in connection with all examinations of the Partnership's
affairs by tax authorities, including, without limitation, resulting
administrative and judicial proceedings, and to expend Partnership funds for
professional services and costs associated therewith. Each Partner and Assignee
agrees to cooperate with the General Partner and to do or refrain from doing any
or all things reasonably required by the General Partner to conduct such
proceedings.
 
    9.4  ORGANIZATIONAL EXPENSES.  The Partnership shall elect to deduct
expenses, if any, incurred by it in organizing the Partnership ratably over a
60-month period as provided in Section 709 of the Code.
 
    9.5  WITHHOLDING.  Notwithstanding any other provision of this Agreement,
the General Partner is authorized to take any action that it determines in its
sole discretion to be necessary or appropriate to cause the Partnership and the
Operating Partnership to comply with any withholding requirements
 
                                      D-46
<PAGE>
established under the Code or any other federal, state or local law including,
without limitation, pursuant to Sections 1441, 1442, 1445 and 1446 of the Code.
To the extent that the Partnership is required to withhold and pay over to any
taxing authority any amount resulting from the allocation or distribution of
income to any Partner or Assignee (including, without limitation, by reason of
Section 1446 of the Code), the amount withheld shall be treated as a
distribution of cash pursuant to Section 5.3 in the amount of such withholding
from such Partner.
 
    9.6  ENTITY-LEVEL TAXATION.  If legislation is enacted that causes the
Partnership to become treated as an association taxable as a corporation or
otherwise subjects the Partnership to entity-level taxation for federal income
tax purposes, the Minimum Quarterly Distribution, First Target Distribution,
Second Target Distribution or Third Target Distribution, as the case may be,
shall be equal to the product obtained by multiplying (a) the amount thereof by
(b) 1 minus the sum of (i) the highest marginal federal corporate (or other
entity, as applicable) income tax rate for the fiscal year of the Partnership in
which such quarter occurs (expressed as a percentage) PLUS (ii) the effective
overall state and local income tax rate (expressed as a percentage) applicable
to the Partnership for the calendar year next preceding the calendar year in
which such quarter occurs (after taking into account the benefit of any
deduction allowable for federal income tax purposes with respect to the payment
of state and local income taxes), but only to the extent of the increase in such
rates resulting from such legislation. Such effective overall state and local
income tax rate shall be determined for the calendar year next preceding the
first calendar year during which the Partnership is taxable for federal income
tax purposes as an association taxable as a corporation or is otherwise subject
to entity-level taxation by determining such rate as if the Partnership had been
subject to such sate and local taxes during such preceding calendar year.
 
    9.7  ENTITY-LEVEL ARREARAGE COLLECTIONS.  If the Partnership is required by
applicable law to pay any federal, state or local income tax on behalf of, or
withhold such amount with respect to, any Partner or Assignee or any former
Partner or Assignee (a) the General Partner shall cause the Partnership to pay
such tax on behalf of such Partner or Assignee or former Partner or Assignee
from the funds of the Partnership; (b) any amount so paid on behalf of, or
withheld with respect to, any Partner or Assignee shall constitute a
distribution out of Available Cash to such Partner or Assignee pursuant to
Section 5.3; and (c) to the extent any such Partner or Assignee (but not a
former Partner or Assignee) is not then entitled to such distribution under this
Agreement and funds in the amount of such distribution are not supplied through
the purchase of APIs (which, except as required under the Omnibus Agreement, the
General Partner has no duty to seek), the General Partner shall be authorized,
without the approval of any Partner or Assignee, to amend this Agreement insofar
as is necessary to maintain the uniformity of intrinsic tax characteristics as
to all Units and to make subsequent adjustments to distributions in a manner
which, in the reasonable judgment of the General Partner, will make as little
alteration as practicable in the priority and amount of distributions otherwise
applicable under this Agreement, and will not otherwise alter the distributions
to which Partners and Assignees are entitled under this Agreement. If the
Partnership is permitted (but not required) by applicable law to pay any such
tax on behalf of, or withhold such amount with respect to, any Partner or
Assignee or former Partner or Assignee, the General Partner shall be authorized
(but not required) to cause the Partnership to pay such tax from the funds of
the Partnership and to take any action consistent with this Section 9.7. The
General Partner shall be authorized (but not required) to take all necessary or
appropriate actions to collect all or any portion of a deficiency in the payment
of any such tax that relates to prior periods and that is attributable to
Persons who were Limited Partners or Assignees when such deficiencies arose,
from such Persons.
 
    9.8  OPINIONS OF COUNSEL.  Notwithstanding any other provision of this
Agreement, if the Partnership is treated as an association taxable as a
corporation at any time or is otherwise taxable for federal income tax purposes
as an entity at any time and, pursuant to the provisions of this Agreement, an
Opinion of Counsel would otherwise be required to the effect that an action will
not cause the Partnership to become so treated as an association taxable as a
corporation or otherwise taxable as an entity for federal income tax purposes,
such requirement for an Opinion of Counsel shall be deemed automatically waived.

<PAGE>
                                   ARTICLE X
                                  CERTIFICATES
 
    10.1  CERTIFICATES.  Upon the Partnership's issuance of Units to any Person,
the Partnership shall issue one or more Certificates in the name of such Person
evidencing the number of such Units being so issued. Certificates shall be
executed on behalf of the Partnership by the General Partner. No Certificate
shall be valid for any purpose until it has been countersigned by the Transfer
Agent.
 
    10.2  REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.  (a) The General
Partner shall cause to be kept on behalf of the Partnership a register in which,
subject to such reasonable regulations as it may prescribe and subject to the
provisions of Section 102(b), the General Partner will provide for the
registration and transfer of Units. The Transfer Agent is hereby appointed
registrar and transfer agent for the purpose of registering Units and transfers
of such Units as herein provided. The Partnership shall not recognize transfers
of Certificates representing Units unless same are effected in the manner
described in this Section 10.2. Upon surrender for registration of transfer of
any Units evidenced by a Certificate, and subject to the provisions of Section
10.2(b), the General Partner on behalf of the Partnership shall execute, and the
Transfer Agent shall countersign and deliver, in the name of the holder or the
designated transferee or transferees, as required pursuant to the holder's
instructions, one or more new Certificates evidencing the same aggregate number
of Units as was evidenced by the Certificate so surrendered.
 
    (b) Except as otherwise provided in Section 11.5, the Partnership shall not
recognize any transfer of Units until the Certificates evidencing such Units are
surrendered for registration of transfer and such Certificates are accompanied
by a Transfer Application duly executed by the transferee (or the transferee's
attorney-in-fact duly authorized in writing). No charge shall be imposed by the
Partnership for such transfer, PROVIDED, that, as a condition to the issuance of
any new Certificate under this Section 10.2, the General Partner may require the
payment of a sum sufficient to cover any tax or other governmental charge that
may be imposed with respect thereto.
 
    10.3  MUTILATED, DESTROYED, LOST OR STOLEN CERTIFICATES.  (a) If any
mutilated Certificate is surrendered to the Transfer Agent, the General Partner
on behalf of the Partnership shall execute, and upon its request the Transfer
Agent shall countersign and deliver in exchange therefor, a new Certificate
evidencing the same number of Units as the Certificate so surrendered.
 
    (b) The General Partner on behalf of the Partnership shall execute, and upon
its request the Transfer Agent shall countersign and deliver a new Certificate
in place of any Certificate previously issued if the Record Holder of the
Certificate:
 
        (i) makes proof by affidavit, in form and substance satisfactory to the
    General Partner, that a previously issued Certificate has been lost,
    destroyed or stolen;
 
        (ii) requests the issuance of a new Certificate before the Partnership
    has notice that the Certificate has been acquired by a purchaser for value
    in good faith and without notice of an adverse claim;
 
        (iii) if requested by the General Partner, delivers to the Partnership a
    bond, in form and substance satisfactory to the General Partner, with surety
    or sureties and with fixed or open penalty as the General Partner may
    reasonably direct, in its sole discretion, to indemnify the Partnership, the
    General Partner and the Transfer Agent against any claim that may be made on
    account of the alleged loss, destruction or theft of the Certificate; and
 
        (iv) satisfies any other reasonable requirements imposed by the General
    Partner.
 
If a Limited Partner or Assignee fails to notify the Partnership within a
reasonable time after he has notice of the loss, destruction or theft of a
Certificate, and a transfer of the Units represented by the Certificate is
registered before the Partnership, the General Partner or the Transfer Agent
receives such notification, the
 
                                      D-48
<PAGE>
Limited Partner or Assignee shall be precluded from making any claim against the
Partnership, the General Partner or the Transfer Agent for such transfer or for
a new Certificate.
 
    (c) As a condition to the issuance of any new Certificate under this Section
10.3, the General Partner may require the payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including, without limitation, the fees and expenses of the
Transfer Agent) reasonably connected therewith.
 
   
    10.4  RECORD HOLDER.  In accordance with Section 10.2(b), the Partnership
shall be entitled to recognize the Record Holder as the Limited Partner or
Assignee with respect to any Units and, accordingly, shall not be bound to
recognize any equitable or other claim to or interest in such Units on the part
of any other Person, whether or not the Partnership shall have actual or other
notice thereof, except as otherwise provided by law or any applicable rule,
regulation, guideline or requirement of any National Securities Exchange on
which the Units are listed for trading. Without limiting the foregoing, when a
Person (such as a broker, dealer, bank, trust company or clearing corporation or
an agent of any of the foregoing) is acting as nominee, agent or in some other
representative capacity for another Person in acquiring and/or holding Units, as
between the Partnership on the one hand and such other Person on the other hand,
such representative Person (a) shall be the Limited Partner or Assignee (as the
case may be) of record and beneficially, (b) must execute and deliver a Transfer
Application and (c) shall be bound by this Agreement and shall have the rights
and obligations of a Limited Partner or Assignee (as the case may be) hereunder
and as provided for herein.
    
 
                                   ARTICLE XI
                             TRANSFER OF INTERESTS
 
    11.1  TRANSFER.  (a) The term "TRANSFER," when used in this Article XI with
respect to a Partnership Interest, shall be deemed to refer to an appropriate
transaction by which the General Partner assigns its Partnership Interest as
General Partner to another Person, by which the holder of a Unit assigns such
Unit to another Person who is or becomes an Assignee or by which a Partner
holding a Deferred Participation Unit or an API assigns such Deferred
Participation Unit or API to another Person, and includes a sale, assignment,
gift, pledge, encumbrance, hypothecation, mortgage, exchange or any other
disposition by law or otherwise.
 
    (b) No Partnership Interest shall be transferred, in whole or in part,
except in accordance with the terms and conditions set forth in this Article XI.
Any transfer or purported transfer of a Partnership Interest not made in
accordance with this Article XI shall be null and void.
 
    (c) Nothing contained in this Article XI shall be construed to prevent a
disposition by the parent entity of the General Partner of all of the issued and
outstanding capital stock of the General Partner.
 
    11.2  TRANSFER OF GENERAL PARTNER'S PARTNERSHIP INTEREST.  (a) The General
Partner may transfer all, but not less than all, of its Partnership Interest as
the General Partner to a single transferee if, but only if, (i) a majority of
the Outstanding Units (excluding any Units owned by the General Partner and its
Affiliates) approve of such transfer and of the admission of such transferee as
General Partner, (ii) the transferee agrees to assume and be bound by the
provisions of this Agreement and Operating Partnership Agreement and (iii) the
Partnership receives an Opinion of Counsel that such transfer would not result
in the loss of limited liability of any Limited Partner or of any limited
partner of the Operating Partnership or cause the Partnership or the Operating
Partnership to be treated as an association taxable as a corporation or
otherwise to be taxed as an entity for federal income tax purposes.
 
                                      D-49
<PAGE>
    (b) Neither Section 11.2(a) nor any other provision of this Agreement shall
be construed to prevent (and all Partners do hereby consent to) (i) the transfer
by the General Partner of all of its Partnership Interest to an Affiliate or
(ii) the transfer by the General Partner of all of its Partnership Interest upon
its merger, consolidation or other combination into any other Person or the
transfer by it of all or substantially all of its assets to another Person if,
in the case of a transfer described in either clause (i) or (ii) of this
sentence, the rights and duties of the General Partner with respect to the
Partnership Interest so transferred are assumed by the transferee and the
transferee agrees to be bound by the provisions of this Agreement and the
Operating Partnership Agreement; PROVIDED, in either such case, that such
transferee furnishes to the Partnership an Opinion of Counsel that such merger,
consolidation, combination, transfer or assumption will not result in a loss of
limited liability of any Limited Partner or of any limited partner of the
Operating Partnership or cause the Partnership or the Operating Partnership to
be treated as an association taxable as a corporation or otherwise be taxed as
an entity for federal income tax purposes. In the case of a transfer pursuant to
this Section 11.2(b), the transferee or successor (as the case may be) shall be
admitted to the Partnership as the General Partner immediately prior to the
transfer of the Partnership Interest, and the business of the Partnership shall
continue without dissolution.
 
    11.3  TRANSFER OF UNITS.  (a) Units may be transferred only in the manner
described in Section 10.2. The transfer of any Units and the admission of any
new Partner shall not constitute an amendment to this Agreement.
 
    (b) Until admitted as a Substituted Limited Partner pursuant to Article XII,
the Record Holder of a Unit shall be an Assignee in respect of such Unit.
Limited Partners may include custodians, nominees, or any other individual or
entity in its own or any representative capacity.
 
    (c) Each distribution in respect of Units shall be paid by the Partnership,
directly or through the Transfer Agent or through any other Person or agent,
only to the Record Holders thereof as of the Record Date set for the
distribution. Such payment shall constitute full payment and satisfaction of the
Partnership's liability in respect of such payment, regardless of any claim of
any Person who may have an interest in such payment by reason of an assignment
or otherwise.
 
    (d) A transferee who has completed and delivered a Transfer Application
shall be deemed to have (i) requested admission as a Substituted Limited
Partner, (ii) agreed to comply with and be bound by and to have executed this
Agreement, (iii) represented and warranted that such transferee has the right,
power and authority and, if an individual, the capacity to enter into this
Agreement, (iv) made the powers of attorney set forth in this Agreement and (v)
given the consents and approvals and made the waivers contained in this
Agreement.
 
    11.4  RESTRICTIONS ON TRANSFERS.  Notwithstanding the other provisions of
this Article XI, no transfer of any Unit or interest therein of any Limited
Partner or Assignee shall be made if such transfer would (a) violate the then
applicable federal or state securities laws or rules and regulations of the
Securities and Exchange Commission, any state securities commission or any other
governmental authorities with jurisdiction over such transfer, (b) result in the
taxation of the Partnership as an association taxable as a corporation or
otherwise subject the Partnership to entity-level taxation for federal income
tax purposes or (c) affect the Partnership's existence or qualification as a
limited partnership under the Delaware Act.
 
    11.5  CITIZENSHIP CERTIFICATES; NON-CITIZEN ASSIGNEES.  (a) If the
Partnership or the Operating Partnership is or becomes subject to any federal,
state or local law or regulation that, in the reasonable determination of the
General Partner, provides for the cancellation or forfeiture of any property in
which the Partnership or the Operating Partnership has an interest based on the
nationality, citizenship or other related status of a Limited Partner or
Assignee, the General Partner may request any Limited Partner or Assignee to
furnish to the General Partner, within 30 days after receipt of such request, an
executed Citizenship Certification or such other information concerning his
nationality, citizenship or other related status (or, if the Limited Partner or
Assignee is a nominee holding for the account of another Person, the
nationality, citizenship or other related status of such Person) as the General
Partner may request. If a
 
                                      D-50
<PAGE>
Limited Partner or Assignee fails to furnish the General Partner within the
aforementioned 30-day period such Citizenship Certification or other requested
information or if upon receipt of such Citizenship Certification or other
requested information the General Partner determines, with the advice of
counsel, that a Limited Partner or Assignee is not an Eligible Citizen, the
Units owned by such Limited Partner or Assignee shall be subject to redemption
in accordance with the provisions of Section 11.6. In addition, the General
Partner may require that the status of any such Limited Partner or Assignee be
changed to that of a Non-citizen Assignee, and, thereupon, the General Partner
shall be substituted for such Non-citizen Assignee as the Limited Partner in
respect of his Units.
 
    (b) The General Partner shall, in exercising voting rights in respect of
Units held by it on behalf of Non-citizen Assignees, distribute the votes in the
same ratios as the votes of Limited Partners in respect of Units other than
those of Non-citizen Assignees are cast, either for, against or abstaining as to
the matter.
 
    (c) Upon dissolution of the Partnership, a Non-citizen Assignee shall have
no right to receive a distribution in kind pursuant to Section 14.4 but shall be
entitled to the cash equivalent thereof, and the General Partner shall provide
cash in exchange for an assignment of the Non-citizen Assignee's share of the
distribution in kind. Such payment and assignment shall be treated for
Partnership purposes as a purchase by the General Partner from the Non-citizen
Assignee of his Partnership Interest (representing his right to receive his
share of such distribution in kind).
 
    (d) At any time after he can and does certify that he has become an Eligible
Citizen, a Non-citizen Assignee may, upon application to the General Partner,
request admission as a Substituted Limited Partner with respect to any Units of
such Non-citizen Assignee not redeemed pursuant to Section 11.6, and upon his
admission pursuant to Section 12.2 the General Partner shall cease to be deemed
to be the Limited Partner in respect of the Non-citizen Assignee's Units.
 
    11.6  REDEMPTION OF INTERESTS.  (a) If at any time a Limited Partner or
Assignee fails to furnish a Citizenship Certification or other information
requested within the 30-day period specified in Section 11.5(a), or if upon
receipt of such Citizenship Certification or other information the General
Partner determines, with the advice of counsel, that a Limited Partner or
Assignee is not an Eligible Citizen, the Partnership may, unless the Limited
Partner or Assignee establishes to the satisfaction of the General Partner that
such Limited Partner or Assignee is an Eligible Citizen or has transferred his
Units to a person who furnishes a Citizenship Certification to the General
Partner prior to the date fixed for redemption as provided below, redeem the
Partnership Interest of such Limited Partner or Assignee as follows:
 
        (i) The General Partner shall not later than the 30th day before the
    date fixed for redemption, give notice of redemption to the Limited Partner
    or Assignee, at his last address designated on the records of the
    Partnership or the Transfer Agent, by registered or certified mail, postage
    prepaid. The notice shall be deemed to have been given when so mailed. The
    notice shall specify the Redeemable Units, the date fixed for redemption,
    the place of payment, that payment of the redemption price will be made upon
    surrender of the Certificate evidencing the Redeemable Units and that on and
    after the date fixed for redemption no further allocations or distributions
    to which the Limited Partner or Assignee would otherwise be entitled in
    respect of the Redeemable Units will accrue or be made.
 
        (ii) The aggregate redemption price for Redeemable Units shall be an
    amount equal to the Current Market Price (the date of determination of which
    shall be the date fixed for redemption) of Units of the class to be so
    redeemed multiplied by the number of Units of each such class included among
    the Redeemable Units. The redemption price shall be paid, in the sole
    discretion of the General Partner, in cash or by delivery of a promissory
    note of the Partnership in the principal amount of the redemption price,
    bearing interest at the rate of 10% annually and payable in three equal
    annual installments of principal together with accrued interest, commencing
    one year after the redemption date.
 
                                      D-51
<PAGE>
        (iii) Upon surrender by or on behalf of the Limited Partner or Assignee,
    at the place specified in the notice of redemption, of the Certificate
    evidencing the Redeemable Units, duly endorsed in blank or accompanied by an
    assignment duly executed in blank, the Limited Partner or Assignee or his
    duly authorized representative shall be entitled to receive the payment
    therefor.
 
        (iv) After the redemption date, Redeemable Units shall no longer
    constitute issued and Outstanding Units.
 
    (b) The provisions of this Section 11.6 shall also be applicable to Units
held by a Limited Partner or Assignee as nominee of a Person determined to be
other than an Eligible Citizen.
 
    (c) Nothing in this Section 11.6 shall prevent the recipient of a notice of
redemption from transferring his Units before the redemption date if such
transfer is otherwise permitted under this Agreement. Upon receipt of notice of
such transfer, the General Partner shall withdraw the notice of redemption,
PROVIDED, the transferee of such Units certifies in the Transfer Application
that he is an Eligible Citizen. If the transferee fails to make such
certification, such redemption shall be effected from the transferee on the
original redemption date.
 
    11.7  TRANSFER OF DEFERRED PARTICIPATION UNITS AND APIS.  (a) A Partner
holding Deferred Participation Units or APIs may transfer all, but not less than
all, of the Deferred Participation Units or APIs, as the case may be, held by
the transferor (i) to an Affiliate of such transferor, (ii) upon such Partner's
merger, consolidation or other combination into any other Person or (iii) in
connection with the transfer by such Partner of all or substantially all of its
assets to another Person.
 
    (b) The Partners holding Deferred Participation Units may receive
Certificates evidencing same. Subject to Section 11.7(a), such Certificates may
be exchanged by the holders for Certificates evidencing Common Units on or after
the date on which such Deferred Participation Units are converted into Common
Units pursuant to the terms of Section 5.7(c).
 
                                  ARTICLE XII
                             ADMISSION OF PARTNERS
 
    12.1  ADMISSION OF INITIAL LIMITED PARTNERS.  Upon the issuance by the
Partnership of Common Units to the Underwriters as described in Section 4.3(b)
and the execution by each such party of a Transfer Application, the General
Partner shall admit the Underwriters to the Partnership as Initial Limited
Partners in respect of the Common Units issued to them.
 
    12.2  ADMISSION OF SUBSTITUTED LIMITED PARTNERS.  By transfer of a Unit in
accordance with Article XI, the transferor shall be deemed to have given the
transferee the right to seek admission as a Substituted Limited Partner subject
to the conditions of, and in the manner permitted under, this Agreement. A
transferor of a Certificate shall, however, only have the authority to convey to
a purchaser or other transferee who does not execute and deliver a Transfer
Application (a) the right to negotiate such Certificate to a purchaser or other
transferee and (b) the right to transfer the right to request admission as a
Substituted Limited Partner to such purchaser or other transferee in respect of
the transferred Units. Each transferee of a Unit (including, without limitation,
any nominee holder or an agent acquiring such Unit for the account of another
Person) who executes and delivers a Transfer Application shall, by virtue of
such execution and delivery, be an Assignee and be deemed to have applied to
become a Substituted Limited Partner with respect to the Units so transferred to
such Person. Such Assignee shall become a Substituted Limited Partner (x) at
such time as the General Partner consents thereto, which consent may be given or
withheld in the General Partner's sole discretion, and (y) when any such
admission is shown on the books and records of the Partnership. If such consent
is withheld, such transferee shall be an Assignee. An Assignee shall have an
interest in the Partnership equivalent to that of a Limited Partner with respect
to allocations and distributions, including, without limitation, liquidating
distributions, of the Partnership.
 
                                      D-52
<PAGE>
With respect to voting rights attributable to Units that are held by Assignees,
the General Partnership shall be deemed to be the Limited Partner with respect
thereto and shall, in exercising the voting rights in respect of such Units on
any matter, vote such Units at the written direction of the Assignee who is the
Record Holder of such Units. If no such written direction is received, such
Units will not be voted. An Assignee shall have no other rights of a Limited
Partner.
 
    12.3  ADMISSION OF SUCCESSOR GENERAL PARTNER.  A successor General Partner
approved pursuant to Section 13.1 or 13.2 or the transferee of or successor to
all of the General Partner's Partnership Interest pursuant to Section 11.2 who
is proposed to be admitted as a successor General Partner shall be admitted to
the Partnership as the General Partner, effective immediately prior to the
withdrawal or removal of the General Partner pursuant to Section 13.1 or 13.2 or
the transfer of the General Partner's Partnership Interest pursuant to Section
11.2; PROVIDED, HOWEVER, that no such successor shall be admitted to the
Partnership until compliance with the terms of Section 11.2 has occurred. Any
such successor shall carry on the business of the Partnership and Operating
Partnership without dissolution. In each case, the admission shall be subject to
the successor General Partner executing and delivering to the Partnership an
acceptance of all of the terms and conditions of this Agreement and such other
documents or instruments as may be required to effect the admission.
 
    12.4  ADMISSION OF ADDITIONAL LIMITED PARTNERS.  (a) A Person (other than
the General Partner, an Initial Limited Partner or a Substituted Limited
Partner) who makes a Capital Contribution to the Partnership in accordance with
this Agreement (other than by virtue of the purchase of APIs) shall be admitted
to the Partnership as an Additional Limited Partner only upon furnishing to the
General Partner (i) evidence of acceptance in form satisfactory to the General
Partner of all of the terms and conditions of this Agreement, including, without
limitation, the power of attorney granted in Section 1.4, and (ii) such other
documents or instructions as may be required in the discretion of the General
Partner to effect such Person's admission as an Additional Limited Partner.
 
    (b) Notwithstanding anything to the contrary in this Section 12.4, no Person
shall be admitted as an Additional Limited Partner without the consent of the
General Partner, which consent may be given or withheld in the General Partner's
sole discretion. The admission of any Person as an Additional Limited Partner
shall become effective on the date upon which the name of such Person is
recorded on the books and records of the Partnership, following the consent of
the General Partner to such admission.
 
    12.5  AMENDMENT OF AGREEMENT AND CERTIFICATE OF LIMITED PARTNERSHIP.  To
effect the admission to the Partnership of any Partner, the General Partner
shall take all steps necessary and appropriate under the Delaware Act to amend
the records of the Partnership and, if necessary, to prepare as soon as
practical an amendment of this Agreement and, if required by law, to prepare and
file an amendment to the Certificate of Limited Partnership and may for this
purpose, among others, exercise the power of attorney granted pursuant to
Section 1.4.
 
                                  ARTICLE XIII
                       WITHDRAWAL OR REMOVAL OF PARTNERS
 
    13.1  WITHDRAWAL OF THE GENERAL PARTNER.  (a) The General Partner shall be
deemed to have withdrawn from the Partnership upon the occurrence of any one of
the following events (each such event herein referred to as an "EVENT OF
WITHDRAWAL":
 
        (i) the General Partner voluntarily withdraws from the Partnership by
    giving written notice to the other Partners (and it shall be deemed that the
    General Partner has withdrawn pursuant to this Section 13.1(a)(i) if the
    General Partner voluntarily withdraws as general partner of OLP-A;
 
        (ii) the General Partner transfers all of its rights as General Partner
    pursuant to Section 11.2;
 
        (iii) the General Partner is removed pursuant to Section 13.2;
 
                                      D-53
<PAGE>
        (iv) the General Partner (A) makes a general assignment for the benefit
    of creditors; (B) files a voluntary bankruptcy petition; (C) files a
    petition or answer seeking for itself a reorganization, arrangement,
    composition, readjustment, liquidation, dissolution or similar relief under
    any law; (D) files an answer or other pleading admitting or failing to
    contest the material allegations of a petition filed against the General
    Partner in a proceeding of the type described in clauses (A)-(C) of this
    Section 13.1(a)(iv); or (E) seeks, consents to or acquiesces in the
    appointment of a trustee, receiver or liquidator of the General Partner or
    of all or any substantial part of its properties;
 
        (v) a final and non-appealable judgment is entered by a court with
    appropriate jurisdiction ruling that the General Partner is bankrupt or
    insolvent, or a final and non-appealable order for relief is entered by a
    court with appropriate jurisdiction against the General Partner, in each
    case under any federal or state bankruptcy or insolvency laws as now or
    hereafter in effect; or
 
        (vi) a certificate of dissolution or its equivalent is filed for the
    General Partner, or 90 days expire after the date of notice to the General
    Partner of revocation of its charter without a reinstatement of its charter,
    under the laws of its state of incorporation.
 
If an Event of Withdrawal specified in Section 13.1(a)(iv), (v) or (vi) occurs,
the withdrawing General Partner shall give notice to the Limited Partners within
30 days after such occurrence. The Partners hereby agree that only the Events of
Withdrawal described in this Section 13.1 shall result in the withdrawal of the
General Partner from the Partnership.
 
    (b) Withdrawal of the General Partner from the Partnership upon the
occurrence of an Event of Withdrawal shall not constitute a breach of this
Agreement under the following circumstances: (i) at any time during the period
prior to January 1, 2003 the General Partner voluntarily withdraws by giving at
least 90 days' advance notice of its intention to withdraw to the Limited
Partners, PROVIDED, that prior to the effective date of such withdrawal the
withdrawal is approved by Limited Partners holding at least a majority of the
Outstanding Units (excluding for purposes of such determination Units owned by
the General Partner and its Affiliates) and the General Partner delivers to the
Partnership an Opinion of Counsel ("WITHDRAWAL OPINION OF COUNSEL") that such
withdrawal (following the selection of the successor General Partner) would not
result in the loss of the limited liability of any Limited Partner or of the
limited partner of the Operating Partnership or cause the Partnership or the
Operating Partnership to be treated as an association taxable as a corporation
or otherwise to be taxed as an entity for federal income tax purposes; (ii) at
any time on or after January 1, 2003, the General Partner voluntarily withdraws
by giving at least 90 days' advance notice to the Limited Partners, such
withdrawal to take effect on the date specified in such notice; (iii) at any
time that the General Partner ceases to be a General Partner pursuant to Section
13.1(a)(ii) or is removed pursuant to Section 13.2; or (iv) notwithstanding
clause (i) of this sentence, at any time that the General Partner voluntarily
withdraws by giving at least 90 days' advance notice of its intention to
withdraw to the Limited Partners, such withdrawal to take effect on the date
specified in the notice, if at the time such notice is given one Person and its
Affiliates (other than the General Partner and its Affiliates) own beneficially
or of record or control at least 50% of the Outstanding Units. The withdrawal of
the General Partner from the Partnership upon the occurrence of an Event of
Withdrawal shall also constitute the withdrawal of the General Partner as
general partner of the Operating Partnership. If the General Partner gives a
notice of withdrawal pursuant to Section 13.1(a)(i), holders of at least a
majority of the Outstanding Units (excluding for purposes of such determination
Units owned by the General Partner and its Affiliates) may, prior to the
effective date of such withdrawal, elect a successor General Partner. The Person
so elected as successor General Partner shall automatically become the successor
general partner of the Operating Partnership, as provided in Operating
Partnership Agreement. If, prior to the effective date of the General Partner's
withdrawal, a successor is not selected by the Limited Partners as provided
herein or the Partnership does not receive a Withdrawal Opinion of Counsel, the
Partnership shall be dissolved in accordance with Section 14.1. Any such
successor General Partner shall be subject to the provisions of Section 12.3.
 
                                      D-54
<PAGE>
    13.2  REMOVAL OF THE GENERAL PARTNER.  The General Partner may be removed if
such removal is approved by Limited Partners holding at least two-thirds of the
Outstanding Units (excluding for purposes of such determination Units owned by
the General Partner and its Affiliates). Any such action by such Limited
Partners for removal of the General Partner must also provide for the election
and succession of a new General Partner. Such removal shall be effective
immediately following the admission of the successor General Partner pursuant to
Article XII. The removal of the General Partner shall also automatically
constitute the removal of the General Partner as general partner of the
Operating Partnership, as provided in the Operating Partnership Agreement. The
Person so elected as successor General Partner shall automatically become the
successor general partner of the Operating Partnership, as provided in the
Operating Partnership Agreement. The right of the Limited Partners holding
Outstanding Units to remove the General Partner shall not exist or be exercised
unless the Partnership has received an opinion opining as to the matters covered
by a Withdrawal Opinion of Counsel. Any such successor General Partner shall be
subject to the provisions of Section 12.3.
 
    13.3  INTEREST OF DEPARTING PARTNER AND SUCCESSOR GENERAL PARTNER.  (a) In
the event of (i) withdrawal of the General Partner under circumstances where
such withdrawal does not violate this Agreement or (ii) removal of the General
Partner by the Limited Partners under circumstances where Cause does not exist,
the Departing Partner shall, at its option exercisable prior to the effective
date of the departure of such Departing Partner, promptly receive from its
successor in exchange for its Partnership Interest as General Partner an amount
in cash equal to the fair market value of the Departing Partner's Partnership
Interest as General Partner, such amount to be determined and payable as of the
effective date of its departure. If the General Partner is removed by the
Limited Partners under circumstances where Cause exists or if the General
Partner withdraws under circumstances where such withdrawal violates this
Agreement or the Operating Partnership Agreement, its successor shall have the
option described in the immediately preceding sentence, and the Departing
Partner shall not have such option. In either case, if the successor acquires
the Departing Partner's Partnership Interest as the general partner, such
successor General Partner must also acquire at such time the general partner
interest of such Departing Partner as general partner of the Operating
Partnership, for an amount in cash equal to the fair market value of such
interest, determined as of the effective date of its departure. In either event,
the Departing Partner shall be entitled to receive all reimbursements due such
Departing Partner pursuant to Section 6.4, including, without limitation, any
employee-related liabilities (including, without limitation, severance
liabilities), incurred in connection with the termination of any employees
employed by the General Partner for the benefit of the Partnership or the
Operating Partnership. Subject to Section 13.3(b), the Departing Partner shall,
as of the effective date of its departure, cease to share in any allocations or
distributions with respect to its Partnership Interest as the General Partner
and Partnership income, gain, loss, deduction and credit will be prorated and
allocated as set forth in Section 5.2(g).
 
    For purposes of this Section 13.3(a), the fair market value of the Departing
Partner's Partnership Interest as the general partner of the Partnership herein
and the partnership interest of such Departing Partner as the general partner of
the Operating Partnership (collectively, the "COMBINED INTEREST") shall be
determined by agreement between the Departing Partner and its successor or,
failing agreement within 30 days after the effective date of such Departing
Partner's departure, by an independent investment banking firm or other
independent expert selected by the Departing Partner and its successor, which,
in turn, may rely on other experts and the determination of which shall be
conclusive as to such matter. If such parties cannot agree upon one independent
investment banking firm or other independent expert within 45 days after the
effective date of such departure, then the Departing Partner shall designate an
independent investment banking firm or other independent expert, the Departing
Partner's successor shall designate an independent investment banking firm or
other independent expert, and such firms or experts shall mutually select a
third independent investment banking firm or independent expert, which shall
determine the fair market value of the Combined Interest. In making its
determination, such independent investment banking firm or other independent
expert shall consider the then current trading price of Units on any
 
                                      D-55
<PAGE>
National Securities Exchange on which Units are then listed, the value of the
Partnership's assets, the rights and obligations of the General Partner and
other factors it may deem relevant.
 
    (b) If the Combined Interest is not acquired in the manner set forth in
Section 13.3(a), the Departing Partner shall become a Limited Partner and the
Combined Interest shall be converted into Common Units pursuant to a valuation
made by an investment banking firm or other independent expert selected pursuant
to Section 13.3(a), without reduction in such Partnership Interest (but subject
to proportionate dilution by reason of the admission of its successor). Any
successor General Partner shall indemnify the Departing Partner as to all debts
and liabilities of the Partnership arising on or after the date on which the
Departing Partner becomes a Limited Partner. For purposes of this Agreement,
conversion of the General Partner's Partnership Interest to Common Units will be
characterized as if the General Partner contributed its Partnership Interest to
the Partnership in exchange for the newly-issued Common Units.
 
    (c) If the option described in Section 13.3(a) is not exercised by the party
entitled to do so, the successor General Partner shall, at the effective date of
its admission to the Partnership, contribute to the capital of the Partnership
cash in an amount such that its Capital Account, after giving effect to such
contribution and any adjustments made to the Capital Accounts of all Partners
pursuant to Section 4.6(d)(i), shall be equal to that percentage of the Capital
Accounts of all Partners that is equal to its Percentage Interest as the General
Partner. In such event, each successor General Partner shall, subject to the
following sentence, be entitled to such Percentage Interest of all Partnership
allocations and distributions and any other allocations and distributions to
which the Departing Partner was entitled. In addition, such successor General
Partner shall cause this Agreement to be amended to reflect that, from and after
the date of such successor General Partner's admission, the successor General
Partner's interest in all Partnership distributions and allocations shall be 1%,
and that of the holders of Outstanding Units shall be 99%.
 
    13.4  REDEMPTION OF APIS UPON REMOVAL WITHOUT CAUSE.  Notwithstanding any
other provision of this Agreement, if KMGP (or any Affiliate of Enron that is a
successor to KMGP as General Partner of the Partnership) is removed as general
partner of the Partnership by the Limited Partners under circumstances where
Cause does not exist, the Special Limited Partner shall have the right to
require the Partnership to redeem immediately any APIs that are then Outstanding
at a price equal to the Unrecovered API Capital attributable thereto.
 
    13.5  WITHDRAWAL OF LIMITED PARTNERS.  No Limited Partner shall have any
right to withdraw from the Partnership; provided, however, that when a
transferee of a Limited Partner's Units becomes a Record Holder, such
transferring Limited Partner shall cease to be a Limited Partner with respect to
the Units so transferred.
 
                                  ARTICLE XIV
                          DISSOLUTION AND LIQUIDATION
 
    14.1  DISSOLUTION.  The Partnership shall not be dissolved by the admission
of Substituted Limited Partners or Additional Limited Partners or by the
admission of a successor General Partner in accordance with the terms of this
Agreement. Upon the removal or withdrawal of the General Partner any successor
General Partner shall continue the business of the Partnership. The Partnership
shall dissolve, and (subject to Section 14.2) its affairs should be wound up,
upon:
 
    (a) the expiration of its term as provided in Section 1.5;
 
    (b) an Event of Withdrawal of the General Partner as provided in Section
13.1(a) (other than Section 13.1(a)(ii)), unless a successor is elected and an
Opinion of Counsel is received as provided in Section 13.1(b) or 13.2 and such
successor is admitted to the Partnership pursuant to Section 12.3;
 
                                      D-56
<PAGE>
    (c) an election to dissolve the Partnership by the General Partner that is
approved by at least two-thirds of the Outstanding Units during the Support
Period and at least a majority of the Outstanding Units thereafter (and all
Limited Partners hereby expressly consent that such approval may be effected
upon written consent of said applicable percentage of the Outstanding Units);
 
    (d) entry of a decree of judicial dissolution of the Partnership pursuant to
the provisions of the Delaware Act; or
 
    (e) the sale of all or substantially all of the assets and properties of the
Partnership and the Operating Partnership.
 
    14.2  CONTINUATION OF THE BUSINESS OF THE PARTNERSHIP AFTER
DISSOLUTION.  Upon (a) dissolution of the Partnership caused by the withdrawal
or removal of the General Partner and following a failure of all Partners,
within 90 days after the withdrawal or removal of the General Partner, to agree
to continue the business of the Partnership and appoint a successor General
Partner as provided in Section 13.1 or 13.2, then within an additional 90 days
or (b) dissolution of the Partnership upon an event constituting an Event of
Withdrawal as defined in Section 13.1(a)(iv), (v) or (vi), then within 180 days
thereafter, a majority of the Outstanding Units may elect to reconstitute the
Partnership and continue its business on the same terms and conditions set forth
in this Agreement by forming a new limited partnership on terms identical to
those set forth in this Agreement and having as a general partner a Person
approved by a majority of the Outstanding Units. Upon any such election by a
majority of the Outstanding Units, all Partners shall be bound thereby and shall
be deemed to have approved same. Unless such an election is made within the
applicable time period as set forth above, the Partnership shall conduct only
activities necessary to wind up its affairs. If such an election is so made,
then:
 
        (i) the reconstituted Partnership shall continue until the end of the
    term set forth in Section 1.5 unless earlier dissolved in accordance with
    this Article XIV;
 
        (ii) if the successor General Partner is not the former General Partner,
    then the interest of the former General Partner shall be treated thenceforth
    as the interest of a Limited Partner and converted into Common Units in the
    manner provided in Section 13.3(b); and
 
        (iii) all necessary steps shall be taken to cancel this Agreement and
    the Certificate of Limited Partnership and to enter into and, as necessary,
    to file a new partnership agreement and certificate of limited partnership,
    and the successor general partner may for this purpose exercise the powers
    of attorney granted the General Partner pursuant to Section 1.4; PROVIDED,
    that the right of a majority of Outstanding Units to approve a successor
    General Partner and to reconstitute and to continue the business of the
    Partnership shall not exist and may not be exercised unless the Partnership
    has received an Opinion of Counsel that (x) the exercise of the right would
    not result in the loss of limited liability of any Limited Partner and (y)
    neither the Partnership, the reconstituted limited partnership nor the
    Operating Partnership would be treated as an association taxable as a
    corporation or otherwise be taxable as an entity for federal income tax
    purposes upon the exercise of such right to continue.
 
    14.3  LIQUIDATION.  Upon dissolution of the Partnership, unless the
Partnership is continued under an election to reconstitute and continue the
Partnership pursuant to Section 14.2, the General Partner, or in the event the
General Partner has been dissolved or removed, become bankrupt as set forth in
Section 13.1 or withdrawn from the Partnership, a liquidator or liquidating
committee approved by a majority of the Outstanding Units, shall be the
Liquidator. The Liquidator (if other than the General Partner) shall be entitled
to receive such compensation for its services as may be approved by a majority
of the Outstanding Units. The Liquidator shall agree not to resign at any time
without 15 days' prior notice and (if other than the General Partner) may be
removed at any time, with or without cause, by notice of removal approved by a
majority of the Outstanding Units. Upon dissolution, removal or resignation of
the Liquidator, a successor and substitute Liquidator (who shall have and
succeed to all rights, powers and duties of the
 
                                      D-57
<PAGE>
original Liquidator) shall within 30 days thereafter be approved by a majority
of the Outstanding Units. The right to approve a successor or substitute
Liquidator in the manner provided herein shall be deemed to refer also to any
such successor or substitute Liquidator approved in the manner herein provided.
Except as expressly provided in this Article XIV, the Liquidator approved in the
manner provided herein shall have and may exercise, without further
authorization or consent of any of the parties hereto, all of the powers
conferred upon the General Partner under the terms of this Agreement (but
subject to all of the applicable limitations, contractual and otherwise, upon
the exercise of such powers, other than the limitation on sale set forth in
Section 6.3(b)) to the extent necessary or desirable in the good faith judgment
of the Liquidator to carry out the duties and functions of the Liquidator
hereunder for and during such period of time as shall be reasonably required in
the good faith judgment of the Liquidator to complete the winding-up and
liquidation of the Partnership as provided for herein. The Liquidator shall
liquidate the assets of the Partnership, and apply and distribute the proceeds
of such liquidation in the following order of priority, unless otherwise
required by mandatory provisions of applicable law:
 
    (a) the payment to creditors of the Partnership, including, without
limitation, Partners who are creditors, in the order of priority provided by
law; and the creation of a reserve of cash or other assets of the Partnership
for contingent liabilities in an amount, if any, determined by the Liquidator to
be appropriate for such purposes; and
 
    (b) to all Partners in accordance with the positive balances in their
respective Capital Accounts, as determined after taking into account all Capital
Account adjustments (other than those made by reason of this clause) for the
taxable year of the Partnership during which the liquidation of the Partnership
occurs (with the date of such occurrence being determined pursuant to Treasury
Regulation Section 1.704-1(b)(2)(ii)(g)); and such distribution shall be made by
the end of such taxable year (or, if later, within 90 days after said date of
such occurrence).
 
    14.4  DISTRIBUTIONS IN KIND.  (a) Notwithstanding the provisions of Section
14.3, which require the liquidation of the assets of the Partnership, but
subject to the order of priorities set forth therein, if prior to or upon
dissolution of the Partnership the Liquidator determines that an immediate sale
of part or all of the Partnership's assets would be impractical or would cause
undue loss to the Partners, the Liquidator may, in its absolute discretion,
defer for a reasonable time the liquidation of any assets except those necessary
to satisfy liabilities of the Partnership (including, without limitation, those
to Partners as creditors) and/or distribute to the Partners or to specific
classes of Partners, in lieu of cash, as tenants in common and in accordance
with the provisions of Section 14.3, undivided interests in such Partnership
assets as the Liquidator deems not suitable for liquidation. Any such
distributions in kind shall be made only if, in the good faith judgment of the
Liquidator, such distributions in kind are in the best interest of the Limited
Partners, and shall be subject to such conditions relating to the disposition
and management of such properties as the Liquidator deems reasonable and
equitable and to any agreements governing the operation of such properties at
such time. The Liquidator shall determine the fair market value of any property
distributed in kind using such reasonable method of valuation as it may adopt.
 
    (b) In accordance with Section 704(c)(1)(B) of the Code, in the case of any
deemed distribution occurring as a result of a termination of the Partnership
pursuant to Section 708(b)(1)(B) of the Code, to the maximum extent possible
consistent with the priorities of Section 14.3, the General Partner shall have
sole discretion to treat the deemed distributions of Partnership assets to
Partners as occurring in a manner that will not cause a shift of the Book-Tax
Disparity attributable to a Partnership asset existing immediately prior to the
deemed distribution to another asset upon the deemed contribution of assets to
the reconstituted Partnership, including, without limitation, deeming the
distribution of any Partnership assets to be made either to the Partner who
contributed such assets or to the transferee of such Partner.
 
    14.5  CANCELLATION OF CERTIFICATE OF LIMITED PARTNERSHIP.  Upon the
completion of the distribution of Partnership cash and property as provided in
Sections 14.3 and 14.4, the Partnership shall be terminated and the Certificate
of Limited Partnership and all qualifications of the Partnership as a foreign
limited
 
                                      D-58
<PAGE>
partnership in jurisdictions other than the State of Delaware shall be cancelled
and such other actions as may be necessary to terminate the Partnership shall be
taken.
 
    14.6  REASONABLE TIME FOR WINDING UP.  A reasonable time shall be allowed
for the orderly winding up of business and affairs of the Partnership and the
liquidation of its assets pursuant to Section 14.3 in order to minimize any
losses otherwise attendant upon such winding up, and the provisions of this
Agreement shall remain in effect between the Partners during the period of
liquidation.
 
    14.7  RETURN OF CAPITAL.  The General Partner shall not be personally liable
for, and shall have no obligation to contribute or loan any monies or property
to the Partnership to enable it to effectuate, the return of the Capital
Contributions of the Limited Partners, or any portion thereof, it being
expressly understood that any such return shall be made solely from Partnership
assets.
 
    14.8  NO CAPITAL ACCOUNT RESTORATION.  No Partner shall have any obligation
to restore any negative balance in its Capital Account upon liquidation of the
Partnership.
 
    14.9  WAIVER OF PARTITION.  Each Partner hereby waives any right to
partition of the Partnership property.
 
                                   ARTICLE XV
           AMENDMENT OF PARTNERSHIP AGREEMENT; MEETINGS; RECORD DATE
 
    15.1  AMENDMENT TO BE ADOPTED SOLELY BY GENERAL PARTNER.  Each Limited
Partner agrees that the General Partner (pursuant to its powers of attorney from
the Limited Partners and Assignees), without the approval of any Limited Partner
or Assignee, may amend any provision of this Agreement, and execute, swear to,
acknowledge, deliver, file and record whatever documents may be required in
connection therewith, to reflect:
 
    (a) a change in the name of the Partnership, the location of the principal
place of business of the Partnership, the registered agent of the Partnership or
the registered office of the Partnership;
 
    (b) admission, substitution, withdrawal or removal of Partners in accordance
with this Agreement;
 
    (c) a change that, in the sole discretion of the General Partner, is
reasonable and necessary or appropriate to qualify or continue the qualification
of the Partnership as a limited partnership or a partnership in which the
limited partners have limited liability under the laws of any state or that is
necessary or advisable in the opinion of the General Partner to ensure that the
Partnership will not be treated as an association taxable as a corporation or
otherwise taxed as an entity for federal income tax purposes;
 
    (d) a change (i) that, in the sole discretion of the General Partner, does
not adversely affect the Limited Partners in any material respect, (ii) that is
necessary or desirable to satisfy any requirements, conditions or guidelines
contained in any opinion, directive, order, ruling or regulation of any federal
or state agency or judicial authority or contained in any federal or state
statute (including, without limitation, the Delaware Act) or that is necessary
or desirable to facilitate the trading of the Units (including, without
limitation, the division of Outstanding Units into different classes to
facilitate uniformity of tax consequences within such classes of Units) or
comply with any rule, regulation, guideline or requirement of any National
Securities Exchange on which the Units are or will be listed for trading,
compliance with any of which the General Partner determines in its sole
discretion to be in the best interests of the Partnership and the Limited
Partners or (iii) that is required to effect the intent of the provisions of
this Agreement or is otherwise contemplated by this Agreement;
 
                                      D-59
<PAGE>

manner being subjected to the provisions of the Investment Company Act of 1940,
as amended, the Investment Advisers Act of 1940, as amended, or "plan asset"
regulations adopted under the Employee Retirement Income Security Act of 1974,
as amended, whether or not substantially similar to plan asset regulations
currently applied or proposed by the United States Department of Labor;
 
    (f) subject to the terms of Section 4.4, an amendment that the General
Partner determines in its sole discretion to be necessary or appropriate in
connection with the authorization for issuance of any class or series of
Partnership Securities pursuant to Section 4.4;
 
    (g) an amendment made after the Deferral Period, the effect of which is to
separate into a separate security (which may be evidenced by a certificate(s) if
determined by the General Partner to be appropriate), separate and apart from
the Common Units, the right of holders of Common Units then Outstanding to
receive any then Cumulative Common Unit Arrearage;
 
    (h) any amendment expressly permitted in this Agreement to be made by the
General Partner acting alone;
 
    (i) an amendment effected, necessitated or contemplated by a Merger

    (j) any other amendments substantially similar to the foregoing.
 
    15.2  AMENDMENT PROCEDURES.  Except as provided in Sections 15.1 and 15.3,
all amendments to this Agreement shall be made in accordance with the following
requirements. Amendments to this Agreement may be proposed only by or with the
consent of the General Partner. Each such proposal shall contain the text of the
proposed amendment. If an amendment is proposed, the General Partner shall seek
the written approval of the requisite percentage of Outstanding Units or call a
meeting of the Limited Partners to consider and vote on such proposed amendment.
A proposed amendment shall be effective upon its approval by at least two-thirds
of the Outstanding Units unless a greater or different percentage is required
under this Agreement. The General Partner shall notify all Record Holders upon
final adoption of any proposed amendment.
 
    15.3  AMENDMENT REQUIREMENTS.  (a) Notwithstanding the provisions of
Sections 15.1 and 15.2, no provision of this Agreement that establishes a
percentage of Outstanding Units required to take any action shall be amended,
altered, changed, repealed or rescinded in any respect that would have the
effect of reducing such voting requirement unless such amendment is approved by
the written consent or the affirmative vote of holders of Outstanding Units
whose aggregate Outstanding Units constitute not less than the voting
requirement sought to be reduced.
 
    (b) Notwithstanding the provisions of Sections 15.1 and 15.2, no amendment
to this Agreement may (i) enlarge the obligations of any Limited Partner without
its consent, (ii) enlarge the obligations of the General Partner without its

of Outstanding Units in relation to other classes of Units must be approved by

affected.
 
                                      D-60
<PAGE>
    (d) Notwithstanding any other provision of this Agreement, except for
amendments pursuant to Section 6.3 or 15.1, no amendments shall become effective
without the approval of at least 95% of the Outstanding Units unless the
Partnership obtains an Opinion of Counsel to the effect that (a) such amendment
will not cause the Partnership or the Operating Partnership to be treated as an
association taxable as a corporation or otherwise taxable as an entity for
federal income tax purposes and (b) such amendment will not affect the limited
liability of any Limited Partner or any limited partner of the Operating
Partnership under applicable law.
 
    (e) This Section 15.3 shall only be amended with the approval of not less
than 95% of the Outstanding Units.
 
    15.4  MEETINGS.  All acts of Limited Partners to be taken hereunder shall be
taken in the manner provided in this Article XV. Meetings of the Limited
Partners may be called by the General Partner or by Limited Partners owning 20%
or more of the Outstanding Units of the class for which a meeting is proposed.
Limited Partners shall call a meeting by delivering to the General Partner one
or more requests in writing stating that the signing Limited Partners wish to
call a meeting and indicating the general or specific purposes for which the
meeting is to be called. Within 60 days after receipt of such a call from
Limited Partners or within such greater time as may be reasonably necessary for
the Partnership to comply with any statutes, rules, regulations, listing
agreements or similar requirements governing the holding of a meeting or the
solicitation of proxies for use at such a meeting, the General Partner shall
send a notice of the meeting to the Limited Partners either directly or
indirectly through the Transfer Agent. A meeting shall be held at a time and
place determined by the General Partner on a date not more than 60 days after
the mailing of notice of the meeting. Limited Partners shall not vote on matters
that would cause the Limited Partners to be deemed to be taking part in the
management and control of the business and affairs of the Partnership so as to
jeopardize the Limited Partners' limited liability under the Delaware Act or the
law of any other state in which the Partnership is qualified to do business.
 
    15.5  NOTICE OF MEETING.  Notice of a meeting called pursuant to Section
15.4 shall be given to the Record Holders in writing by mail or other means of
written communication in accordance with Section 17.1 The notice shall be deemed
to have been given at the time when deposited in the mail or sent by other means
of written communication.
 
    15.6  RECORD DATE.  For purposes of determining the Limited Partners
entitled to notice of or to vote at a meeting of the Limited Partners or to give
approvals without a meeting as provided in Section 15.11, the General Partner
may set a Record Date, which shall not be less than 10 nor more than 60 days
before (a) the date of the meeting (unless such requirement conflicts with any
rule, regulation, guideline or requirement of any National Securities Exchange
on which the Units are listed for trading, in which case the rule, regulation,
guideline or requirement of such exchange shall govern) or (b) in the event that
approvals are sought without a meeting, the date by which Limited Partners are
requested in writing by the General Partner to give such approvals.
 
    15.7  ADJOURNMENT.  When a meeting is adjourned to another time or place,
notice need not be given of the adjourned meeting and a new Record Date need not
be fixed, if the time and place thereof are announced at the meeting at which
the adjournment is taken, unless such adjournment shall be for more than 45
days. At the adjourned meeting, the Partnership may transact any business which
might have been transacted at the original meeting. If the adjournment is for
more than 45 days or if a new Record Date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given in accordance with this Article
XV.
 
    15.8  WAIVER OF NOTICE; APPROVAL OF MEETING; APPROVAL OF MINUTES.  The
transactions of any meeting of Limited Partners, however called and noticed, and
whenever held, shall be as valid as if had at a meeting duly held after regular
call and notice, if a quorum is present either in person or by proxy, and if,
either before or after the meeting, each of the Limited Partners entitled to
vote, present in person or by proxy, signs a written waiver of notice or an
approval of the holding of the meeting or an approval of the minutes
 
                                      D-61
<PAGE>
thereof. All waivers and approvals shall be filed with the Partnership records
or made a part of the minutes of the meeting. Attendance of a Limited Partner at
a meeting shall constitute a waiver of notice of the meeting, except when the
Limited Partner does not approve, at the beginning of the meeting, of the
transaction of any business because the meeting is not lawfully called or
convened; and except that attendance at a meeting is not a waiver of any right
to disapprove the consideration of matters required to be included in the notice
of the meeting, but not so included, if the disapproval is expressly made at the
meeting.
 
    15.9  QUORUM.  Two-thirds of the Outstanding Units of the class for which a
meeting has been called represented in person or by proxy shall constitute a
quorum at a meeting of Limited Partners of such class unless any such action by
the Limited Partners requires approval by holders of a majority in interest of
such Units, in which case the quorum shall be a majority (excluding, in either
case, if such are to be excluded from the vote, Outstanding Units owned by the
General Partner and its Affiliates). At any meeting of the Limited Partners duly
called and held in accordance with this Agreement at which a quorum is present,
the act of Limited Partners holding Outstanding Units that in the aggregate
represent a majority of the Outstanding Units entitled to vote and be present in
person or by proxy at such meeting shall be deemed to constitute the act of all
Limited Partners, unless a greater or different percentage is required with
respect to such action under the provisions of this Agreement, in which case the
act of the Limited Partners holding Outstanding Units that in the aggregate
represent at least such greater or different percentage shall be required. The
Limited Partners present at a duly called or held meeting at which a quorum is
present may continue to transact business until adjournment, notwithstanding the
withdrawal of enough Limited Partners to leave less than a quorum, if any action
taken (other than adjournment) is approved by the required percentage of
Outstanding Units specified in this Agreement. In the absence of a quorum, any
meeting of Limited Partners may be adjourned from time to time by the
affirmative vote of a majority of the Outstanding Units represented either in
person or by proxy, but no other business may be transacted, except as provided
in Section 15.7.
 
    15.10  CONDUCT OF MEETING.  The General Partner shall have full power and
authority concerning the manner of conducting any meeting of the Limited
Partners or solicitation of approvals in writing, including, without limitation,
the determination of Persons entitled to vote, the existence of a quorum, the
satisfaction of the requirements of Section 15.4, the conduct of voting, the
validity and effect of any proxies and the determination of any controversies,
votes or challenges arising in connection with or during the meeting or voting.
The General Partner shall designate a Person to serve as chairman of any meeting
and shall further designate a Person to take the minutes of any meeting, in
either case including, without limitation, a Partner or a director or officer of
the General Partner. All minutes shall be kept with the records of the
Partnership maintained by the General Partner. The General Partner may make such
other regulations consistent with applicable law and this Agreement as it may
deem advisable concerning the conduct of any meeting of the Limited Partners or
solicitation of approvals in writing, including, without limitation, regulations
in regard to the appointment of proxies, the appointment and duties of
inspectors of votes and approvals, the submission and examination of proxies and
other evidence of the right to vote, and the revocation of approvals in writing.
 
    15.11  ACTION WITHOUT A MEETING.  Any action that may be taken at a meeting
of the Limited Partners may be taken without a meeting if an approval in writing
setting forth the action so taken is signed by Limited Partners owning not less
than the minimum percentage of the Outstanding Units that would be necessary to
authorize or take such action at a meeting at which all the Limited Partners
were present and voted. Prompt notice of the taking of action without a meeting
shall be given to the Limited Partners who have not approved in writing. The
General Partner may specify that any written ballot submitted to Limited
Partners for the purpose of taking any action without a meeting shall be
returned to the Partnership within the time period, which shall be not less than
20 days, specified by the General Partner. If a ballot returned to the
Partnership does not vote all of the Units held by the Limited Partner, the
Partnership shall be deemed to have failed to receive a ballot for the Units
that were not voted. If approval
 
                                      D-62
<PAGE>
of the taking of any action by the Limited Partners is solicited by any Person
other than by or on behalf of the General Partner, the written approvals shall
have no force and effect unless and until (a) they are deposited with the
Partnership in care of the General Partner, (b) approvals sufficient to take the
action proposed are dated as of a date not more than 90 days prior to the date
sufficient approvals are deposited with the Partnership and (c) an Opinion of
Counsel is delivered to the General Partner to the effect that the exercise of
such right and the action proposed to be taken with respect to any particular
matter (i) will not cause the Limited Partners to be deemed to be taking part in
the management and control of the business and affairs of the Partnership so as
to jeopardize the Limited Partners' limited liability, (ii) will not jeopardize
the status of the Partnership as a partnership under applicable tax laws and
regulations and (iii) is otherwise permissible under the state statutes then
governing the rights, duties and liabilities of the Partnership and the
Partners.
 
    15.12  VOTING AND OTHER RIGHTS.  (a) Only those Record Holders of Units on
the Record Date set pursuant to Section 15.6 (and also subject to the
limitations contained in the definition of "Outstanding") shall be entitled to
notice of, and to vote at, a meeting of Limited Partners or to act with respect
to matters as to which the holders of the Outstanding Units have the right to
vote or to act. All references in this Agreement to votes of, or other acts that
may be taken by, the Outstanding Units shall be deemed to be references to the
votes or acts of the Record Holders of such Outstanding Units.
 
    (b) With respect to Units that are held for a Person's account by another
Person (such as a broker, dealer, bank, trust company or clearing corporation,
or an agent of any of the foregoing), in whose name such Units are registered,
such broker, dealer or other agent shall, in exercising the voting rights in
respect of such Units on any matter, and unless the arrangement between such
Persons provides otherwise, vote such Units in favor of, and at the direction
of, the Person who is the beneficial owner, and the Partnership shall be
entitled to assume it is so acting without further inquiry. The provisions of
this Section 15.12(b) (as well as all other provisions of this Agreement) are
subject to the provisions of Section 10.4.
 
                                  ARTICLE XVI

<PAGE>
Surviving Business Entity, the cash, property or general or limited partnership
interests, rights, securities or obligations of any limited partnership,
corporation, trust or other entity (other than the Surviving Business Entity)
which the holders of such general or limited partnership interest are to receive

or the written consent.
 
    (b) The Merger Agreement shall be approved upon receiving the affirmative
vote or consent of at least two-thirds of the Outstanding Units during the
Support Period and at least a majority of the Outstanding Units thereafter
unless the Merger Agreement contains any provision which, if contained in an
amendment to this Agreement, the provisions of this Agreement or the Delaware
Act would require the vote or consent of a greater percentage of the Outstanding
Units or of any class of Limited Partners, in which case such greater percentage
vote or consent shall be required for approval of the Merger Agreement.
 
    (c) After such approval by vote or consent of the Limited Partners, and at
any time prior to the filing of the certificate of merger pursuant to Section
16.4, the merger or consolidation may be abandoned pursuant to provisions

                             RIGHT TO ACQUIRE UNITS
 
    17.1  RIGHT TO ACQUIRE UNITS.  (a) Notwithstanding any other provision of
this Agreement, if at any time not more than 20% of the total Units of any class
then Outstanding are held by Persons other than the General Partner and its
Affiliates, the General Partner shall then have the right, which right it may
assign and transfer to the Partnership or any Affiliate of the General Partner,
exercisable in its sole discretion, to purchase all, but not less than all, of
the Units of such class then Outstanding held by Persons other than the General
Partner and its Affiliates, at the greater of (x) the Current Market Price as of
the date five days prior to the date that the notice described in Section
17.1(b) is mailed, and (y) the highest cash price paid by the General Partner or
any of its Affiliates for any such Unit purchased during the 90-day period
preceding the date that the notice described in Section 17.1(b) is mailed. As
used in this Agreement, (i) "CURRENT MARKET PRICE" as of any date of any class
of Units listed or admitted to trading on any National Securities Exchange means
the average of the daily Closing Prices (as hereinafter defined) per Unit of
such class for the 20 consecutive Trading Days (as hereinafter defined)
immediately prior to such date; (ii) "CLOSING PRICE" for any day means the last
sale price on such day, regular way, or in case no such sale takes place on such
day, the average of the closing bid and asked prices on such day, regular way,
in either case as reported in the principal consolidated transaction reporting
system with respect to securities listed on the principal National Securities
Exchange on which the Units of such class are listed or admitted to trading or
if the Units of such class are not listed or admitted to trading on any National
Securities Exchange, the last quoted price on such day or, if not so quoted, the
average of the high bid and low asked prices on such day in the over-the-counter
market as reported by the National Association of Securities Dealers, Inc.
Automated Quotation System or such other system then in use, or if on any such
day the Units of such class are not quoted by any such organization, the average
of the closing bid and asked prices on such day as furnished by a professional
market maker making a market in the Units of such class selected by the Board of
Directors of the General Partner, or if on any such day no market maker is
making a market in the Units of such class, the fair value of such Units on such
day as determined reasonably and in good faith by the Board of Directors of the
General Partner; and (iii) "TRADING DAY" means a day on which the principal
National Securities Exchange on which the Units of any class are listed or
admitted to trading is open for the transaction of business or, if Units of a
class are not listed or admitted to trading on any National Securities Exchange,
a day on which banking institutions in New York City generally are open.
 
    (b) If the General Partner, any Affiliate of the General Partner or the
Partnership elects to exercise the right to purchase Units granted pursuant to
Section 17.1(a), the General Partner shall deliver to the Transfer Agent notice
of such election to purchase (the "NOTICE OF ELECTION TO PURCHASE") and shall
cause the Transfer Agent to mail a copy of such Notice of Election to Purchase
to the Record Holders of Units (as of a Record Date selected by the General
Partner) at least 10, but not more than 60 days prior to the Purchase Date. Such
Notice of Election to Purchase shall also be published in daily newspapers of
general circulation printed in the English language and published in the Borough
of Manhattan, New York. The Notice of Election to Purchase shall specify the
Purchase Date and the price (determined in accordance with Section 17.1(a) at
which Units will be purchased and state that the General Partner, its Affiliate
or the
 
                                      D-65
<PAGE>
Partnership, as the case may be, elects to purchase such Units, upon surrender
of Certificates representing such Units in exchange for payment, at such office
or offices of the Transfer Agent as the Transfer Agent may specify, or as may be
required by any National Securities Exchange on which the Units are listed or
admitted to trading. Any such Notice of Election to Purchase mailed to a Record
Holder of Units at his address as reflected in the records of the Transfer Agent
shall be conclusively presumed to have been given whether or not the owner
receives such notice. On or prior to the Purchase Date, the General Partner, its
Affiliate or the Partnership, as the case may be, shall deposit with the
Transfer Agent cash in an amount sufficient to pay the aggregate purchase price
of all the Units to be purchased in accordance with this Section 17.1. If the
Notice of Election to Purchase shall have been duly given as aforesaid at least
ten days prior to the Purchase Date, and if on or prior to the Purchase Date the
deposit described in the preceding sentence has been made for the benefit of the
holders of Units subject to purchase as provided herein, then from and after the
Purchase Date, notwithstanding that any Certificate shall not have been
surrendered for purchase, all rights of the holders of such Units (including,
without limitation, any rights pursuant to Articles IV, V and XIV) shall
thereupon cease, except the right to receive the purchase price (determined in
accordance with Section 17.1(a)) for Units therefor, without interest, upon
surrender to the Transfer Agent of the Certificates representing such Units, and
such Units shall thereupon be deemed to be transferred to the General Partner,
its Affiliate or the Partnership, as the case may be, on the record books of the
Transfer Agent and the Partnership, and the General Partner or any Affiliate of
the General Partner, or the Partnership, as the case may be, shall be deemed to
be the owner of all such Units from and after the Purchase Date and shall have
all rights as the owner of such Units (including, without limitation, all rights
as owner of such Units pursuant to Articles IV, V and XIV).
 
    (c) At any time from and after the Purchase Date, a holder of an Outstanding
Unit subject to purchase as provided in this Section 17.1 may surrender his
Certificate, as the case may be, evidencing such Unit to the Transfer Agent in
exchange for payment of the amount described in Section 17.1(a), therefor,
without interest thereon.

delivered in person or when sent by first-class United States mail or by other
means of written communication to the Partner or Assignee at the address
described below. Any notice, payment or report to be given or made to a Partner
or Assignee hereunder shall be deemed conclusively to have been given or made,
and the obligation to give such notice or report or to make such payment shall
be deemed conclusively to have been fully satisfied, upon sending of such
notice, payment or report to the Record Holder of such Unit at his address as
shown on the records of the Transfer Agent or as otherwise shown on the records
of the Partnership, regardless of any claim of any Person who may have an

of any assignment or otherwise. An affidavit or certificate of making of any
notice, payment or report in accordance with the provisions of this Section 18.1
executed by the General Partner, the Transfer Agent or the mailing organization
shall be prima facie evidence of the giving or making of such notice, payment or
report. If any notice, payment or report addressed to a Record Holder at the
address of such Record Holder appearing on the books and records of the Transfer
Agent or the Partnership is returned by the United States Post Office marked to
indicate that the United States Postal Service is unable to deliver it, such
notice, payment or report and any subsequent notices, payments and reports shall
be deemed to have been duly given or made without further mailing (until such
time as such Record Holder or another Person notifies the Transfer Agent or the
Partnership of a change in his address) if they are available for the Partner or
Assignee at the principal office of the Partnership for a period of one year
from the date of the giving or making of such notice, payment or report to the
other Partners and Assignees. Any notice to the
 
                                      D-66
<PAGE>
Partnership shall be deemed given if received by the General Partner at the
principal office of the Partnership designated pursuant to Section 1.3. The
General Partner may rely and shall be protected in relying on any notice or
other document from a Partner, Assignee or other Person if believed by it to be
genuine.
 
    18.2  REFERENCES.  Except as specifically provided otherwise, references to
"Articles" and "Sections" are to Articles and Sections of this Agreement.
 
    18.3  PRONOUNS AND PLURALS.  Whenever the context may require, any pronoun
used in this Agreement shall include the corresponding masculine, feminine or
neuter forms, and the singular form of nouns, pronouns and verbs shall include
the plural and vice versa.
 
    18.4  FURTHER ACTION.  The parties shall execute and deliver all documents,
provide all information and take or refrain from taking action as may be
necessary or appropriate to achieve the purposes of this Agreement.
 
    18.5  BINDING EFFECT.  This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their heirs, executors, administrators,
successors, legal representatives and permitted assigns.
 
    18.6  INTEGRATION.  This Agreement constitutes the entire agreement among
parties hereto pertaining to the subject matter hereof and supersedes all prior
agreements and understandings pertaining thereto.
 
    18.7  CREDITORS.  None of the provisions of this Agreement shall be for the
benefit of, or shall be enforceable by, any creditor of the Partnership.
 
    18.8  WAIVER.  No failure by any party to insist upon the strict performance
of any covenant, duty, agreement or condition of this Agreement or to exercise
any right or remedy consequent upon a breach thereof shall constitute waiver of
any such breach or any other covenant, duty, agreement or condition.
 
    18.9  COUNTERPARTS.  This Agreement may be executed in counterparts, all of
which together shall constitute an agreement binding on all parties hereto,
notwithstanding that all such parties are not signatories to the original or the
same counterpart. Each party shall become bound by this Agreement immediately
upon affixing its signature hereto or, in the case of a Person acquiring a Unit,
upon accepting the certificate evidencing such Unit or executing and delivering
a Transfer Application as herein described, independently of the signature of
any other party.
 
    18.10  APPLICABLE LAW.  This Agreement shall be construed in accordance with
and governed by the laws of the State of Delaware, without regard to the
principles of conflicts of law.
 
    18.11  INVALIDITY OF PROVISIONS.  If any provision of this Agreement is or
becomes invalid, illegal or unenforceable in any respect, the validity, legality
and enforceability of the remaining provisions contained herein shall not be
affected thereby.

the Partnership, and (B) the then current holder of the general partnership
interest in the Partnership will receive all other assets of the Partnership

    D.  In order to effect the transactions contemplated by the Purchase

    Agreement"), the Special Liquidation Gain (as defined below) shall be
    allocated:
    
<PAGE>
   
           (i) FIRST, to the Common Unit holders (other than the General
       Partner, but including the Former General Partner), until the Capital
       Account of each such holder is equal to the value of the rights to
       receive common units of Kinder Morgan Energy Partners, L.P. to which that
       holder is entitled pursuant to the Special Liquidation; and
    
 
   
               (ii) FINALLY, the remainder to the General Partner.
    
 
   
    For purposes of this Section 5.2(l), the term "Special Liquidation Gain'
    shall mean the gain realized by the Partnership on the hypothetical sale of
    all of the assets of the Partnership immediately prior to the Special
    Liquidation at their fair market value.'
    
 
   
    2.  SECTION 14.10. A new Section 14.10 is hereby added to the Partnership
Agreement, to follow Section 14.9 and to read in full as follows:

       Partners who are creditors, in order of priority provided by law;
    
 
   
           (b) SECOND, the rights to receive Common Units of Kinder Morgan
       Energy Partners, L.P. to the holders of the Common Units (other than the

       with their respective Partnership Interests;
    
 
   
           (c) FINALLY, the limited partnership interests in the Operating
       Partnership and any other remaining assets to the General Partner.
    
 
   
    3. RATIFICATION. Except as expressly amended hereby, the Partnership
Agreement is hereby ratified and confirmed, and shall continue in full force and
effect.
    
 
   
    IN WITNESS WHEREOF, the General Partner has executed and delivered this

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The KMEP Partnership Agreement provides that KMEP will indemnify any person
who is or was an officer or director of the KM General Partner or any departing
partner, to the fullest extent permitted by law. In addition, KMEP may
indemnify, to the extent deemed advisable by the KM General Partner and to the
fullest extent permitted by law, any person who is or was serving at the request
of the KM General Partner or any affiliate of the KM General Partner or any
departing partner as an officer or director of the KM General Partner, a
departing partner or any of their Affiliates (as defined in KMEP Partnership
Agreement) ("Indemnitees") from and against any and all losses, claims, damages,
liabilities (joint or several), expenses (including, without limitation, legal
fees and expenses), judgments, fines, settlements and other amounts arising from
any and all claims, demands, actions, suits or proceedings, whether civil,
criminal, administrative or investigative, in which any Indemnitee may be
involved, or is threatened to be involved, as a party or otherwise, by reason of
its status as an officer or director or a person serving at the request of KMEP
in another entity in a similar capacity, provided that in each case the
Indemnitee acted in good faith and in a manner which such Indemnitee believed to
be in or not opposed to the best interests of KMEP and, with respect to any
criminal proceeding, had no reasonable cause to believe its conduct was
unlawful. Any indemnification under these provisions will be only out of the
assets of KMEP and the KM General Partner shall not be personally liable for, or
have any obligation to contribute or loan funds or assets to KMEP to enable it
to effectuate, such indemnification. KMEP is authorized to purchase (or to
reimburse the KM General Partner or its affiliates for the cost of) insurance
against liabilities asserted against and expenses incurred by such person to
indemnify such person against such liabilities under the provisions described
above.
 
    Article XII(c) of the Certificate of Incorporation of the KM General Partner
(the "Corporation" therein) contains the following provisions relating to
indemnification of directors and officers:
 
       (c) Each director and each officer of the corporation (and such holder's
    heirs, executors and administrators) shall be indemnified by the corporation
    against expenses reasonably incurred by him in connection with any claim
    made against him or any action, suit or proceeding to which he may be made a
    party, by reason of such holder being or having been a director or officer
    of the corporation (whether or not he continues to be a director or officer
    of the corporation at the time of incurring such expenses), except in cases
    where the claim made against him shall be admitted by him to be just, and
    except in cases where such action, suit or proceeding shall be settled prior
    to adjudication by payment of all or a substantial portion of the amount
    claimed, and except in cases in which he shall be adjudged in such action,
    suit or proceeding to be liable or to have been derelict in the performance
    of such holder's duty as such director or officer. Such right of
    indemnification shall not be exclusive of other rights to which he may be
    entitled as a matter of law.
 
    Richard D. Kinder, the Chairman of the Board of Directors and Chief
Executive Officer of the KM General Partner, and William V. Morgan, a Director
and Vice Chairman of the KM General Partner, are also officers and directors of
KMI and are entitled to similar indemnification from KMI pursuant to KMI's
certificate of incorporation and bylaws.

Re: 26,615,926 Common Units
 
Ladies and Gentlemen:
 
    We have acted as your counsel in connection with the preparation of the
Registration Statement on From S-4 (Registration no. 333-      ) (the
"Registration Statement") and the Joint Proxy Statement/ Prospectus filed with
the Securities and Exchange Commission pursuant to the Securities Act of 1933,
as amended (the "Act") on January 20, 1998. The Registration Statement covers a
total of 26,615,926 Common Units ("Common Units") representing limited partner
interests in Kinder Morgan Energy Partners, L.P. (the "Partnership") to be
issued and distributed by the Partnership pursuant to that certain Purchase
Agreement dated October 18, 1997 (the "Purchase Agreement") between the
Partnership, Kinder Morgan G.P., Inc., Santa Fe Pacific Pipeline Partners, L.P.,
Santa Fe Pacific Pipelines, Inc., and SFP Pipeline Holdings, Inc.
 
    The opinions expressed herein are given only with respect to the present
status of the substantive laws of the state of Delaware. We express no opinion
as to any matter arising under the laws of any other jurisdiction.
 
    In rendering the opinions set forth below, we have examined and relied on
the following: (1) the Registration Statement and the Joint Proxy
Statement/Prospectus; (2) the Purchase Agreement; (3) the Partnership's Second
Amended and Restated Agreement of Limited Partnership dated January 14, 1998;
and (4) such other documents, materials, and authorities as we have deemed
necessary in order to enable us to render our opinions set forth below.
 
    Based on and subject to the foregoing and other qualifications set forth
below, we are of the opinion that the Common Units which are to be issued and
distributed by the Partnership as contemplated by the Registration Statement,
the Joint Proxy Statement/Prospectus and the Purchase Agreement have been duly
authorized for issuance and when issued and distributed will be duly issued and,
on the assumption that the Limited Partners of the Partnership take no part in
the control of the Partnership's business and otherwise act in conformity with
the provisions of the Partnership's Second Amended and Restated Agreement of
Limited Partnership regarding control and management of the Partnership
(Articles VI and VII), such Common Units will be fully paid and nonassessable.
 
    We hereby consent to the filing of this letter as an Exhibit to the
Registration Statement and to the reference to this firm under the headline
"Legal Matters" in the Joint Proxy Statement/Prospectus forming part of the
Registration Statement. This consent is not to be construed as an admission that
we are a person whose consent is required to be filed with the Registration
Statement under the provisions of the Act.

Re:  Kinder Morgan Energy Partners, L.P.: Form S-4 Registration Statement
 
Ladies and Gentlemen:
 
    We have acted as counsel to Kinder Morgan Energy Partners, L.P. a Delaware
limited partnership (the "Partnership"), and Kinder Morgan G.P., Inc., a
Delaware corporation and the general partner of the Partnership, in connection
with the preparation of the Registration Statement on Form S-4 (Registration no.
333-     ) (the "Registration Statement") and the Joint Proxy
Statement/Prospectus filed with the Securities and Exchange Commission pursuant
to the Securities Act of 1933, as amended (the "Act") on January 20, 1998 (the
"Joint Proxy Statement"). The Registration Statement covers a total of
26,615,926 Common Units ("Common Units") representing limited partner interests
in the Partnership to be issued and distributed by the Partnership pursuant to
that certain Purchase Agreement dated October 18, 1997, between and among the
Partnership, Kinder Morgan, G.P., Inc., Santa Fe Pacific Pipeline Partners, L.P.
("Santa Fe"), Santa Fe Pacific Pipelines, Inc., and SFP Pipeline Holdings, Inc.
(the "Purchase Agreement"). Capitalized terms used herein without definition
have the respective meanings set forth in the Joint Proxy Statement.
 
    In rendering the opinions set forth below, we have examined and relied on
the following: (1) the Registration Statement and the Joint Proxy Statement; (2)
the Purchase Agreement; (3) the Partnership's Amended and Restated Agreement of
Limited Partnership dated August 6, 1992 and the Partnership's Second Amended
and Restated Agreement of Limited Partnership dated January 14, 1998; and (4)
such other documents, materials, and authorities as we have deemed necessary in
order to enable us to render our opinions set forth below.
 
    In addition, our opinions are based on the facts and circumstances set forth
in the Joint Proxy Statement and in certain representations and covenants made
by the Partnership and Santa Fe. Our opinion as to certain matters is based, in
part, on the opinion of Mayer, Brown & Platt, as set forth in the Joint Proxy
Statement. We have not made an independent investigation of such facts,
representations and the basis for such opinion of Mayer, Brown & Platt. Our
opinion as to the matters set forth herein could change as a result of changes
in facts and circumstances, changes in the terms of the documents reviewed by
us, or changes in the law subsequent to the date hereof.

    Based upon and subject to the foregoing and assuming compliance with all
provisions of the documents referenced above, we are of the opinion that for
federal income tax purposes (i) the Partnership and its operating partnerships
are and will continue to be classified as partnerships and not as associations
taxable as corporations; (ii) a pre-transaction Common Unit holder of the
Partnership who continues to hold the Partnership's Common Units will not
realize gain or loss due to the issuance and distribution of the 26,615,926
Common Units and the contribution of the SF Operating Partnership LP Interest to
the Partnership in exchange for such Common Units; and (iii) each person who
acquires beneficial ownership of the Partnership's Common Units pursuant to the
Purchase Agreement and has executed and delivered a letter of transmittal, and
either has been admitted or is pending admission to the Partnership as an
additional limited partner or who has acquired beneficial ownership and whose
Common Units are held by a nominee, will be treated as a partner of the
Partnership for federal income tax purposes.
 
    Further, we are of the opinion that the discussion of federal income tax
consequences set forth in the Joint Proxy Statement under the headings
"Summary--Certain Federal Income tax Considerations", "Risk Factors--Tax Risks"
and "Material Federal Income Tax Considerations" are accurate in all material
respects as to matters of law and legal conclusions.
 
    This opinion may be relied upon by you, the pre-Transaction holders of
Common Units of Santa Fe and the Partnership and Mayer, Brown & Platt. We hereby
consent to the filing of this opinion as an Exhibit to the Joint Proxy Statement
and to all references to this firm under the heading "Summary-- Certain Federal
Income Tax Considerations", "Risk Factors--Tax Risks" and "Material Federal
Income Tax Considerations" in the Joint Proxy Statement forming part of the
Registration Statement.

                Re: Santa Fe Pacific Partners, L.P. Purchase Agreement
                    --------------------------------------------------

Ladies and Gentlemen:

     We have acted as counsel to Santa Fe Pacific Pipeline Partners, L.P. a 
Delaware master limited partnership ("Santa Fe"), and Santa Fe Pacific 
Pipelines, Inc., a Delaware corporation and general partner of Santa Fe ("SF 
General Partner") in connection with the transactions contemplated in the 
Purchase Agreement between Santa Fe, the SF General Partner, SFP Pipeline 
Holdings, Inc., Kinder Morgan Energy Partners, L.P., a Delaware master 
limited partnership ("KMEP") and Kinder Morgan G.P., Inc., a Delaware 
corporation and general partner of KMEP (the "KM General Partner") dated as 
of October 18, 1997 (the "Purchase Agreement").  In that capacity we have 
also participated in the preparation of the Joint Proxy Statement of KMEP and 
Santa Fe and Prospectus of KMEP (the "Joint Proxy Statement") being furnished 
to holders of common units of KMEP and Santa Fe in connection with the 
solicitation of proxies to approve these transactions.  Capitalized terms 
used herein without definition have the respective meanings set forth in the 
Joint Proxy Statement.

     In formulating our opinions set forth herein, we have reviewed and 
relied upon the partnership agreements of Santa Fe and SFPP, L.P. (the "SF 
Operating Partnership"), the 



<PAGE>

Purchase Agreement, the Joint Proxy Statement, such other documents and 
information provided by you, and such applicable provisions of law as we have 
considered necessary or desirable for purposes of the opinions expressed 
herein. In addition, we have relied upon certain representations made by you 
and the KM General Partner as to factual matters as well as upon 
representations and warranties made in or pursuant to the documents referred 
to above and upon the originals, or copies certified or otherwise identified 
to our satisfaction, of such records, documents, certificates or other 
instruments as in our judgment are necessary or appropriate to enable us to 
render the opinions expressed below. These opinions are further based upon 
the opinion of Morrison & Hecker that KMEP is treated as a partnership for 
federal income tax purposes and not as a corporation.  For purposes of our 
opinions, we have not made an independent investigation of all facts set 
forth in such documents, the representations from you or the KMEP General 
Partner or the opinion of Morrison & Hecker.  We have, consequently relied 
upon your representations that the information presented in such documents or 
otherwise furnished to us accurately and completely describes all material 
facts.

     Our opinions expressed herein are based on the Internal Revenue Code of 
1986, as amended (the "Code")(1)  the Treasury regulations promulgated 
thereunder, and the interpretations of the Code and such regulations by the 
courts and the Internal Revenue Service (the "IRS"), all as they are in 
effect and exist at the date of this letter.  It should be noted that 
statutes, regulations, judicial decisions, and administrative interpretations 
are subject to change at any time and, in some circumstances, with 
retroactive effect.  A material change that is made after the date hereof in 
any of the foregoing bases for our opinion, could adversely affect our 
conclusion.

     Pursuant to the terms of the Purchase Agreement, Santa Fe will contribute
substantially all of its limited partner interests in the SF Operating
Partnership to KMEP in exchange for the right to receive 1.39 KMEP Common Units
for each outstanding Santa Fe Common Unit (the "Exchange").  An affiliate of
KMEP, OLP-D, will purchase the general partner interest in Santa Fe from the SF
General Partner for $84.4 million in cash and KMEP will transfer the limited
partner interests in the SF Operating Partnership to OLP-D.  Immediately
following these transfers, Santa Fe will be liquidated (the "Liquidation") with
each Santa Fe Common Unit holder receiving the right to receive 1.39 KMEP Common
Units for each Santa Fe Common Unit held by such holder (the "Liquidation
Distribution") and the successor to the Santa Fe general partner interest
receiving any remaining limited partner interests in the SF Operating
Partnership

and any other remaining assets of Santa Fe.  KMEP will not issue certificates 
representing fractional interests in KMEP Common Units to former Santa Fe 
Common Unit holders with respect to their right to receive KMEP Common Units. 
Instead, KMEP will make a cash distribution in exchange for any former Santa 
Fe Common Unit holder's fractional interest in KMEP Common Units (the 
"Fractional Unit Payments").  The transactions contemplated by the Purchase 
Agreement are referred to herein as the "Transaction."

     Treasury Regulations Sections 301.7701-1, 301.7701-2 and 301.7701-3, the 
so-called "Check-the-Box Regulations," generally provide that most entities 
formed after December 31, 1996 may choose to be classified as either a 
partnership or a corporation.  For entities already in existence on January 
1, 1997, the Check-the-Box Regulations provide that its classification as of 
that time will be respected for all periods prior to January 1, 1997 if (i) 
the entity had a reasonable basis for the claimed classification, (ii) the 
entity recognized federal income tax consequences of any change in 
classification within five years prior to January 1, 1997 and (iii) the 
entity was not notified prior to May 8, 1996, that the entity's 
classification was under examination. Prior to the finalization of the 
Check-the-Box Regulations, the classification of an entity was determined 
under a four factor test primarily developed in case law and incorporated 
into the former regulations under Section 7701.  Under this four factor test, 
an entity was classified as a partnership if it lacked at least two of the 
corporate characteristics of (1) continuity of life, (2) limited liability , 
(3) centralized management and (4) free transferability of interests.

     Under the terms of the partnership agreements of Santa Fe and the SF 
Operating Partnership, both entities lack continuity of life.  Furthermore 
based on the representation of the SF General Partner with respect to its net 
worth, Santa Fe and the SF Operating Partnership  lacked limited liability 
for purposes of the four factor test.  Consequently, Santa Fe and the SF 
Operating Partnership both have a reasonable basis for their claimed 
classifications as partnerships and this classification did not change during 
the five years prior to January 1, 1997.  Thus, further based on the 
representation of the SF General Partner that no classification issues have 
been raised on examination, each of Santa Fe and the SF Operating Partnership 
qualify as a partnership under the Check-the-Box Regulations.

     Under Section 7704, publicly traded partnerships will generally be 
treated as corporations for federal income tax purposes.  However,  Section 
7704(c) provides an exception if at least 90% of the gross income of the 
publicly traded partnership for each taxable year is comprised of "qualifying 
income."  Section 7704(d) defines qualifying income to include, among other 
things, income and gains derived from the exploration, development, mining or 

<PAGE>

production, processing, refining, transportation (which includes pipelines) 
or marketing of any natural resource (including oil, natural gas or products 
thereof).  Based on the representation of the SF General Partner that less 
than 10% of the gross income of each of Santa Fe (as determined by looking 
through to the income of the SF Operating Partnership) and the SF Operating 
Partnership is derived from sources other than qualifying income, Santa Fe 
qualifies for the exception provided by Section 7704(c).

     Section 721 provides that, as a general rule, no gain or loss is 
recognized by a partnership or by any of its partners upon a contribution of 
property to a partnership in exchange for an interest in the partnership.  In 
addition, Section 731 provides that, as a general rule, neither a partnership 
nor a partner recognizes gain or loss on the distribution by the partnership 
of property, other than money, to a partner.  However, the tax free treatment 
under Section 721 does not apply to a contribution of property to a 
partnership that is classified as an "investment company" under the Code, to 
a contribution of property that is treated as a "disguised sale" of the 
contributed property under the Code, or to the extent that the contributing 
partners receive consideration other than an interest in the partnership.  
Further, depending upon the circumstances, a partner's deemed relief from 
liabilities, either in connection with a contribution to a partnership or a 
distribution from a partnership or a repayment of part or all of such 
liabilities, could cause the partner to recognize taxable gain on a 
contribution or distribution that would otherwise qualify for tax free 
treatment under Section 721 or Section 731.  Tax free treatment under Section 
731 also does not apply to the extent that any money (which, for this 
purpose, includes certain marketable securities) distributed by the 
partnership exceeds the adjusted tax basis of the partner's interest in the 
partnership immediately before the distribution.

     If KMEP is considered an "investment company," as defined by reference 
to Section 351, the Exchange will not be tax free under Section 721.  
Treasury Regulation Section 1.351-1(c) and Code Section 351(e) provide that a 
transfer will be treated as having been made to an investment company if the 
transfer results in a diversification of the interests of the transferor, and 
the transferee is (a) a regulated investment company ("RIC"), (b) a real 
estate investment trust ("REIT"), or (c) a partnership more than 80% of the 
value of whose assets are held for investment and are stock or securities 
(including for this purpose, money, options, forward contracts, derivatives 
and certain other assets, but excluding for this purpose, interests in 
partnerships that are not publicly traded partnerships) or interests in RICs 
or REITs. Although the transfer by Santa Fe to KMEP will result in the 
diversification of the interests of Santa Fe and the Santa Fe Common Unit 
holders, KMEP is not a REIT or a RIC, and, based upon certain representations 
of the KM General Partner, less than 80% of the value of the assets of KMEP 
is comprised of stocks or securities (as defined in Section 351(e)(1)(B)) or 
interests in RICs or 

<PAGE>

Page 5

REITs.  Consequently, KMEP will not be considered an investment company at 
the time of the Exchange.

     The Exchange also would not be tax free to Santa Fe and the Santa Fe 
Common Unit holders to the extent that it is treated as a "disguised sale" of 
property under the Code or Treasury Regulations.  Section 707(a)(2)(B) and 
the Treasury Regulations thereunder (the "Disguised Sale Rules") generally 
provide that a partner's contribution of property to a partnership and a 
simultaneous or subsequent transfer of money or other consideration 
(including the assumption by the partnership of a liability of the partner or 
taking of property by the partnership subject to a liability) from the 
partnership to the partner will be presumed to be a sale, in whole or in 
part, of such property by the partner to the partnership.  Except for the 
possible treatment of the Fractional Unit Payment discussed below, there is 
no cash or other property being received by Santa Fe and, based on the 
representation of the SF General Partner, Santa Fe is not being relieved of 
any liabilities for purposes of applying these rules. 

     There is a possibility that the IRS may seek to ignore the form of the 
Transaction and take the position that the Santa Fe Common Unit holders' 
receipt of the Fractional Unit Payments from KMEP in partial exchange for 
their Santa Fe Common Units should be treated under the Disguised Sale Rules 
as a payment of money by KMEP to Santa Fe in exchange for a portion of the 
limited partner interest in the SF Operating Partnership, followed by a 
distribution of the Fractional Unit Payment and KMEP Common Units to the 
respective partners upon the Liquidation.  If the IRS were to take this 
position and prevail, Santa Fe would recognize gain to the extent that the 
total amount of the Fractional Unit Payments exceeds Santa Fe's adjusted tax 
basis in the portion of the SF Operating Partnership limited partner 
interests considered to be sold to KMEP under the Disguised Sale Rules.  The 
taxable gain would be allocated ratably to Santa Fe Common Unit holders, and 
a Santa Fe Common Unit holder could be allocated a share of such gain, even 
though such holder may not receive a Fractional Unit Payment.

     Although there is no definitive authority on this point, it is more 
likely than not that the form of the Transaction will be respected and that 
the Fractional Unit Payment will be treated as a cash distribution from KMEP 
to the Santa Fe Common Unit holders, rather than as a payment to Santa Fe as 
part of a disguised sale.  Because it is more likely than not that Santa Fe 
will not be considered as receiving the Fraction Unit Payments from KMEP and 
because Santa Fe is not being relieved of liabilities or receiving cash or 
property pursuant to the Exchange, the Exchange will not be taxable under the 
Disguised Sale Rules.

     Through the interaction of Sections 705, 722, 742 and 752, a partner 
includes in the tax basis for such partner's partnership interest a share of 
the partnership's liabilities, determined in accordance with the Treasury 
Regulations under Section 752.  The partner also includes in the tax basis 
for such partnership interest any capital contributions that such partner 
actually made to the partnership and such partner's allocable share of all 
partnership income and gains, less the amount of all distributions that such 
partner receives from the partnership and such partner's allocable share of 
all partnership losses. Under Section 752(b), if a partner's share of the 
partnership liabilities is reduced for any reason, the partner is deemed to 
have received a cash distribution equal to the amount of such reduction.  
Under Section 731, the partner will recognize gain as a result of this deemed 
cash distribution if, and to the extent that, the deemed cash distribution 
exceeds its adjusted tax basis for its partnership interest.  Based upon the 
representation of the SF General Partner, Santa Fe will not be relieved of 
liabilities in excess of its tax basis in the limited partner interests in 
the SF Operating Partnership upon the Exchange.  Because Santa Fe will not be 
deemed to receive a distribution of cash from KMEP in excess of its tax 
basis, Santa Fe will not recognize gain on the Exchange, subject to the 
treatment of the Fractional Unit Payment as discussed above. 

     Because (i) KMEP is not an investment company, (ii) Santa Fe will not 
receive cash, property or relief from liabilities in excess of its tax basis 
in the limited partner interests in the SF Operating Partnership and (iii) 
subject to the possible exception of the treatment of Fractional Units as 
discussed above, a disguised sale will not be considered to have occurred, 
Section 721 will apply to Exchange and Santa Fe will not recognize gain 
thereupon (subject to the possible exception of Fractional Unit Payments).

     Under Section 731(b), a partnership does not recognize any gain or loss 
upon distributions to its partners or upon liquidation of the partnership. 
Consequently, Santa Fe will not recognize gain as a result of the Liquidation 
or the Liquidation Distribution.

     Under Section 731, a partner will recognize gain as a result of a 
distribution from a partnership if the partnership distributes money and the 
amount of money received by the partner exceeds such partner's adjusted tax 
basis in the partnership interest prior to the distribution.  The amount of 
gain is limited to this excess.  Generally, for purposes of Section 731, a 
distribution of readily marketable securities is treated as a distribution of 
cash.

     Because the KMEP Common Units are tradeable, the Liquidation 
Distribution would be considered a distribution of cash under this general 
rule.  However, Treasury Regulation Section 1.731-2(d)(1)(ii) provides that a 
distribution of marketable securities will not be treated as a

distribution of cash if (i) such securities are acquired by the partnership 
in a non-recognition transaction, (ii) the value of any marketable securities 
transferred to KMEP in such transaction is less than 20% of the value of all 
assets transferred to KMEP and (iii) the partnership distributes the 
securities within five years.  Because (i) as discussed above, the Exchange 
will constitute a non-recognition transaction under Section 721(a) of the 
Code, (ii) the SF Operating Partnership limited partner interests to be 
transferred to KMEP in the Exchange are not readily marketable and (iii) 
Santa Fe will immediately distribute the rights to KMEP Common Units pursuant 
to the Liquidation Distribution, the Liquidation Distribution will not be 
treated as a distribution of cash to a Santa Fe Common Unit holder.

     As explained above, a reduction in a partner's share of partnership 
liabilities constitutes a deemed cash distribution.  Because no liabilities 
are currently allocated to the Santa Fe Common Unit holders (as based upon 
the representation of the SF General Partner), no such holder will be 
relieved of any liabilities of Santa Fe upon the Liquidation Distribution and 
thus no gain will be triggered by these rules.

     Since, as discussed above, it is more likely than not that the 
Fractional Unit Payments will be treated as a cash distribution by KMEP to 
the Santa Fe Common Unit holders at the time they become KMEP Common Unit 
holders pursuant to the Transaction, under Section 731 of the Code, a Santa 
Fe Common Unit holder will recognize gain as a result of the Transaction if, 
and only to the extent that, any Fractional Unit Payment made to such holder 
exceeds the sum of such holder's tax basis in the newly acquired KMEP Common 
Units plus such holder's tax basis in KMEP Common Units held prior to the 
Transaction, if any. 

     Under Section 732(b) of the Code, the tax basis of the KMEP Common Units 
received by a Santa Fe Common Unit holder will be equal to the adjusted tax 
basis of such holder's Santa Fe Common Units.  This basis will be immediately 
reduced, but not below zero, by the amount of the Fractional Unit Payment 
received, if any.

     Under Section 735(b) of the Code, and based upon a representation of the 
SF General Partner that there has been no tax termination of Santa Fe or the 
SF Operating Partnership since 1988, the holding period of the KMEP Common 
Units in the hands of the Santa Fe Common Unit holders will include the 
holding period of the SF Operating Partnership limited partner interests in 
the hands of Santa Fe (which commenced no later than January 1, 1989), except 
to the extent the value of the partnership interests are attributable to 
Section 751 assets other than depreciation recapture (E.G., unrealized 
receivables, inventory items and capital improvements not held by the SF 
Operating Partnership for more than 12 months).  The holding period of the

Page 8


KMEP Common Units received by a Santa Fe Common Unit holder attributable to 
such Section 751 assets of the SF Operating Partnership will begin on the day 
following the date of the Transaction. 

     Based upon and subject to the foregoing, it is our opinion that, for
federal income tax purposes:

      (i)   Santa Fe and the SF Operating Partnership are partnerships and not
            corporations or associations taxable as corporations;

     (ii)   Subject to the uncertainty involving the treatment of the
            Fractional Unit Payments, Santa Fe will not recognize gain or loss
            as a result of the transfer of limited partner interests in the SF
            Operating Partnership to KMEP in exchange for rights to receive
            KMEP Common Units or as a result of such KMEP Common Units being
            distributed to, and received by, Santa Fe Common Unit holders;

     (iii)  Subject to the uncertainty involving the treatment of the
            Fractional Unit Payments, Santa Fe Common Unit holders will not
            recognize any gain or loss (A) on the transfer of limited partner
            interests in the SF Operating Partnership by Santa Fe to KMEP in
            exchange for rights to receive KMEP Common Units, (B) upon the
            receipt of the right to receive KMEP Common Units pursuant to the
            liquidation of Santa Fe or the receipt of such KMEP Common Units,
            (C) upon the receipt of a Fractional Unit Payment from KMEP, except
            to the extent that the Fractional Unit Payment received by any such
            holder exceeds such holder's tax basis in  KMEP Common Units, or
            (D) otherwise as a result of the Transaction;

     (iv)   The tax basis of the KMEP Common Units received by a Santa Fe
            Common Unit holder will be equal to the adjusted tax basis of such
            holder's Santa Fe Common Units, reduced, but not below zero, by the
            amount of the Fractional Unit Payment received, if any; and 

     (v)    The holding period of the KMEP Common Units in the hands of the
            Santa Fe Common Unit holders will include the holding period of the
            SF Operating Partnership limited partner interests in the hands of
            Santa Fe, except to the extent the value of the SF Operating
            Partnership is attributable to Section 751 assets other than
            depreciation recapture (e.g. unrealized receivables, inventory
            items and capital improvements not held by the SF Operating
            Partnership for more than 12

            months), in which case the holding period of the KMEP Common 
            Units received by a Santa Fe Common Unit holder attributable 
            to such Section 751 assets will begin on the day following the 
            date of the Transaction.

It is possible that the IRS would treat the Fractional Unit Payment as a payment
of money by KMEP to Santa Fe in exchange for a portion of the limited partner
interests in the SF Operating Partnership, followed by a distribution of the
Fractional Unit Payment and the KMEP Common Units to the Santa Fe Common Unit
holders, with the result that Santa Fe Common Unit holders could recognize gain
as a result of the Transaction even if such holder does not receive a Fractional
Unit Payment.  However, we are of the opinion that it is more likely than not
that the Fractional Unit Payments will be characterized as a cash distribution
directly from KMEP to the Santa Fe Common Unit holders in which case, the
federal income tax consequences will be as described in paragraphs (ii) and
(iii) above.

     Finally, based on the foregoing, we are of the opinion that the discussion
of federal income tax consequences set forth in the Joint Proxy Statement under
the headings "Summary -- Certain Federal Income Tax Considerations -- Tax
Consequences of the Transaction" and "Material Federal Income Tax Considerations
- -- Tax Consequences of the Exchange and Distribution" accurately sets forth the
material federal income tax consequences of the Transaction to holders of Santa
Fe Common Units.

     Other than as expressly stated above, we express no opinion on any issue
relating to Santa Fe, KMEP, any Operating Partnership or to any investment in
KMEP.

Chief Financial Officer, Vice President
KINDER MORGAN ENERGY PARTNERS, L.P.
1301 McKinney, Suite 3450
Houston, TX 77010

Dear Mr. Dehaemers:

At your request and pursuant to your authorization, we have conducted a 
valuation of the fixed assets and certain other assets of Kinder Morgan 
Energy Partners, L.P. and Santa Fe Pacific Pipeline Partners, L.P.  The 
purpose of our valuation has been to express our opinion of the Fair Market 
Value of these assets as of November 1, 1997.  It is our understanding that 
the results of this valuation will be relied upon by Kinder Morgan Energy 
Partners, L.P. in connection with certain tax and financial reporting 
requirements associated with its acquisition of Santa Fe Pipeline Partners, 
L.P.

For purposes of this valuation, the term "Fair Market Value" is defined as 
the amount at which the appraised assets would likely exchange between a 
willing buyer and a willing seller, neither being under any compulsion to buy 
or sell and both acting with reasonable knowledge of all relevant facts.  In 
performing this valuation, we have assumed that the appraised assets would 
remain in place and in use as part of the ongoing business enterprise.

As requested, we have prepared this letter to set forth our opinion of the 
Fair Market Value of the fixed assets and certain other assets and the book 
value of the non-appraised assets which consist of current assets, 
construction in progress and certain other assets.  These amounts are set 
forth on the following page:

January [20], 1998

The Special Committee of the Board of Directors of 
 Santa Fe Pacific Pipelines, Inc.
1100 Town & Country Road
Orange, CA 92868


Gentlemen:

You have requested our opinion as to the fairness, from a financial point of 
view, to the holders of the common units ("Santa Fe Common Units") of Santa 
Fe Pacific Pipeline Partners, L.P. ("Santa Fe") of the consideration to be 
received by such holders pursuant to the terms and subject to the conditions 
set forth in the Purchase Agreement dated October 18, 1997 (the "Purchase 
Agreement"), among Kinder Morgan Energy Partners, L.P. ("Kinder Morgan"), 
Kinder Morgan G.P., Inc. ("KM General Partner"), Santa Fe, Santa Fe Pacific 
Pipelines, Inc. ("SF General Partner") and SFP Pipeline Holdings, Inc. As 
more fully described in the Purchase Agreement, (i) a limited partnership 
recently formed by Kinder Morgan and KM General Partner ("New L.P.") will 
purchase the general partnership interest in Santa Fe from SF General Partner 
for $90.2 million; (ii) Kinder Morgan will purchase from Santa Fe its 98.9899%
limited partnership interest in SFPP, L.P. (the "Operating Partnership") in 
consideration of a number of common units of Kinder Morgan ("Kinder Morgan 
Common Units") such that, upon liquidation of Santa Fe, each holder of Santa 
Fe Common Units shall be distributed a right to receive 1.39 Kinder Morgan 
Common Units in respect of each Santa Fe Common Unit (the "Exchange Ratio" or 
the "Liquidation Distribution"); (iii) New L.P. (as general partner of Santa 
Fe) shall cause Santa Fe to be liquidated and shall distribute (x) to the 
holders of Santa Fe Common Units, the Liquidation Distribution, (y) to New 
L.P., Santa Fe's remaining limited partnership interest in the Operating 
Partnership and any remaining assets of Santa Fe; (iv) Kinder Morgan and the 
SF General Partner will cause the Agreement of Limited Partnership of the 
Operating Partnership to be amended and restated to (x) provide for a 
98.9899% general partnership interest for which the prior limited partnership 
interest owned by New L.P. shall be exchanged, and (y) provide for a 1.0101% 
special limited partnership interest ("Special Limited Partnership Interest") 
for which the prior general partnership interest of the SF General Partner 
shall be exchanged; and (v) New L.P. shall cause the Operating Partnership to 
redeem that portion of the Special Limited Partnership Interest equal to a 
0.5101% interest in the Operating Partnership for $5.8 million. For purposes 
hereof, the steps described above shall be collectively referred to herein as 
the Transactions.

In arriving at our opinion, we reviewed the Purchase Agreement and held 
discussions with certain senior officers and other representatives and 
advisors of the SF General Partner and Santa Fe and certain senior officers 
and other representatives and advisors of Kinder Morgan concerning the 
business, operations and prospects of Santa Fe and Kinder Morgan, 
respectively.

We examined certain publicly available business and financial information 
relating to Santa Fe and Kinder Morgan as well as certain financial forecasts 
and other financial and operating data which were provided to or otherwise 
discussed with us by the respective managements of Santa Fe and Kinder 
Morgan, including information relating to certain strategic implications and 
operational benefits anticipated to result from the Transactions. We reviewed 
the financial terms of the Transactions as set forth in the Purchase 
Agreement in relation to, among other things, current and historical market 
prices, trading volumes and yields of the Santa Fe Common Units and the 
Kinder Morgan Common Units; historical and projected earnings and other 
operating data of Santa Fe and Kinder Morgan; and the capitalization and 
financial condition of Santa Fe and Kinder Morgan. We specifically considered 
the consideration to be received by the SF General Partner. We also analyzed 
certain financial, stock market and other publicly available information 
relating to the businesses of other companies whose operations we 
considered relevant. We also evaluated the potential pro forma impact of the 
Transactions on Kinder Morgan. In addition to the foregoing, we conducted 
such other analyses and examinations and considered such other financial, 
economic and market criteria as we deemed appropriate to arrive at our 
opinion.

In rendering our opinion, we have assumed and relied upon, without 
independent verification, the accuracy and completeness of all financial and 
other information and data publicly available or furnished to or otherwise 
reviewed by or discussed with us. With respect to financial forecasts and 
other information furnished to or otherwise reviewed by or discussed with us, 
we have been advised by the managements of Santa Fe and Kinder Morgan that 
such forecasts and other information were reasonably prepared on bases 
reflecting the best currently available estimates and judgments of Santa Fe 
and Kinder Morgan as to the expected future financial performance of Santa Fe 
and Kinder Morgan and the strategic implications and operational benefits 
anticipated to result from the Transactions. We further relied on the 
assurances of management of Santa Fe and Kinder Morgan that they were unaware 
of any facts that would make the information or forecasts provided to us 
incomplete or misleading. In particular, we were provided with and relied 
upon a schedule from Kinder Morgan of estimated cost savings that Kinder 
Morgan expects to achieve as a result of the Transactions. We were not 
engaged to assess the accuracy of the information provided to us or the 
reasonableness of the projections or other forward looking information 
provided to us. Specifically, with respect to the legal and regulatory 
proceedings described in the Joint Proxy Statement/Prospectus relating to the 
Transactions, we were not in a position to evaluate the impact of such 
proceedings and assumed that these matters will be resolved in a manner which 
will not adversely affect in any material respect the financial forecasts on 
which we relied for purposes of our opinion. We have not made or been 
provided with an independent evaluation or appraisal of the assets or 
liabilities (contingent or otherwise) of Santa Fe or Kinder Morgan nor have 
we made any physical inspection of the properties or assets of Santa Fe or 
Kinder Morgan. Our opinion, as set forth herein, relates to the relative 
values of Santa Fe and Kinder Morgan. We are not expressing any opinion as to 
what the value of the Kinder Morgan Common Units actually will be when issued 
to the holders of the Santa Fe Common Units or the prices at which the Kinder 
Morgan Common Units will trade subsequent to the Transactions. In addition, 
we have not been asked to nor do we express an opinion as to

the relative merits of the Transactions as compared to any alternative 
business strategies that might exist for Santa Fe or the effect of any other 
transaction in which Santa Fe might engage. We were not engaged to solicit 
third-party indications of interest in acquiring all or any part of Santa Fe. 
Our opinion is necessarily based upon information available to us, and 
financial, stock market and other conditions and circumstances existing and 
disclosed to us, as of the date hereof.

We have been engaged to render financial advisory services to the Special 
Committee (the "Special Committee") of the Board of Directors of SF General 
Partner in connection with the Transactions and have received a fee for our 
services, including a fee in connection with the delivery of this opinion. In 
the ordinary course of our business, we and our affiliates may actively trade 
or hold the securities of Santa Fe and Kinder Morgan for our own account or 
for the account of customers and, accordingly, may at any time hold long or 
short positions in such securities. In addition, we and our affiliates 
(including Travelers Group Inc. and its affiliates) may maintain 
relationships with Santa Fe and Kinder Morgan.

Our advisory services and the opinion expressed herein are provided for the 
information of the Special Committee in its evaluation of the proposed 
Transactions, and our opinion is not intended to be nor does it constitute a 
recommendation to any unitholder as to how such unitholders should vote on 
the proposed Transactions. Our opinion may not be published or otherwise used 
or referred to, nor shall any public reference to Smith Barney be made, 
without our prior written consent.

Subject to the foregoing and based upon our experience as investment bankers, 
our work as described above and other factors we deemed relevant, we are of 
the opinion that, as of the date hereof, the Exchange Ratio is fair, from a 
financial point of view, to the holders of the Santa Fe Common Units.

Very truly yours,


SMITH BARNEY INC.
