Item 2.  Acquisition or Disposition of Assets.

Acquisition of Santa Fe Pacific Pipelines, L.P.

     On March 6, 1998,  Kinder Morgan Operating L.P. "D" ("OLP-D")  acquired 99%
of SFPP, L.P., the operating  partnership of Santa Fe Pacific Pipeline Partners,
L.P. ("Santa Fe"). SFPP, L.P. owned  substantially  all of Santa Fe's assets and
conducted all of its business activities.  The Partnership acquired the interest
of Santa Fe's common unit  holders in SFPP,  L.P. in exchange  for 26.6  million
Common Units (1.39 Common Units for each Santa Fe common unit).  The Partnership
paid  $84.4  million  to Santa  Fe  Pacific  Pipelines,  Inc.  (the "SF  General
Partner") in exchange for the general partner interest in Santa Fe.

      Also on March 6, 1998,  SFPP, L.P.  redeemed from the SF General Partner a
 .5% interest in SFPP, L.P. for $5.8 million.  The redemption was paid from SFPP,
L.P.'s cash reserves. After the redemption,  the SF General Partner continues to
own a .5% special limited partner  interest in SFPP, L.P. and OLP-D owns a 99.5%
general  partner  interest  in SFPP,  L.P.  The  Partnership  owns a 99% limited
partner  interest in OLP-D and the general partner of the Partnership  owns a 1%
general partner interest in OLP-D.

      The Partnership and a special committee of independent directors of the SF
General  Partner  determined  the  purchase  price for Santa Fe  (including  the
exchange  ratio  for the  Santa  Fe  common  units)  through  negotiations.  The
Partnership  financed  the  purchase  of the Santa Fe general  partner  interest
through its  syndicated  credit  facility  with First Union  National  Bank,  as
administrative  agent,  swingline lender and issuing bank,  Goldman Sachs Credit
Partners,  as syndication  agent,  and the other lenders that are parties to the
credit facility.

      At the  time  of  the  acquisition,  Santa  Fe  was  one  of  the  largest
independent  refined petroleum  products pipelines in the United States serving,
six Western states with approximately 3,300 miles of common carrier pipeline and
thirteen truck loading terminals.

Formation of Shell CO2 Company

           On March 5, 1998, the Partnership and affiliates of Shell Oil Company
("Shell")  formed Shell CO2 Company,  Ltd.  ("Shell  CO2"),  which will explore,
produce,  market and transport CO2 for enhanced oil recovery onshore  throughout
the continental  United States.  The Partnership  received a 20% limited partner
interest in Shell CO2 in exchange for  contributing  its Central Basin  Pipeline
and $25 million in cash.  Affiliates of Shell contributed their interests in CO2
reserves, pipelines, and other related assets in exchange for an 80% interest in
Shell CO2.

      An  affiliate  of Shell will be the general  partner of Shell CO2 and will
manage its operations.

                                        2

<PAGE>



      The  Partnership is entitled,  if there is sufficient  available cash from
operations,  to a fixed  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,  the  Partnership's  cash  distributions  will be  increased  or
decreased  so that the total  cash  distributions  during the first six years of
Shell CO2's existence will be equal to the Partnership's  percentage interest of
the  cumulative  cash  distributions  of  Shell  CO2  during  such  period  on a
present-value basis (discounted at 10%).

      At any time  after  March 5,  2002,  Shell has the right to  purchase  the
Partnership's interest in Shell CO2 and the Partnership has the right to require
Shell to purchase the  Partnership's  interest in Shell CO2. The purchase  price
for the  Partnership's  interest  in Shell CO2 will be at a  discount  from fair
value in the event the  Partnership  exercises its put option,  and at a premium
over fair value in the event Shell exercises its call option.  The amount of the
discount or premium  declines during the period from March 5, 2003 through March
5, 2006 and is  thereafter  fixed at a 5%  discount/premium.  If the parties are
unable to agree to the fair value of the  Partnership's  interest  in Shell CO2,
then the Partnership and Shell will use an agreed-upon  appraisal methodology to
determine fair value.

                                       -5-

     (c) Pursuant to the terms of the Master  Agreement,  KM and Shell and their
respective Affiliates are required to transfer to the Partnership,  all of their
right,  title,  and interest in the various  assets,  projects  and/or  business
opportunities   described  in  each  Partner's  respective  General  Conveyance,
Assignment and Bill of Sale Agreement;  except that Shell and its Affiliates are
not  required  now or in the future to  transfer to the  Partnership  any of the
assets,  projects and/or business  opportunities  that are described in Schedule
1.9(c) or any other  business  or activity  not  related to the  business of the
Partnership or reasonable  future expansions or extensions of such businesses or
activities (collectively, the "Excluded Ventures"). Notwithstanding any contrary
provision in this  Agreement  during the period that KM or Shell or any of their
Affiliates is a Partner, the Partnership shall have for 30 days after notice the
preferential first right over any Partner or their Affiliates,  to own, acquire,
develop or otherwise  exploit assets,  projects  and/or  business  opportunities
(including minority interests and non-controlling interests) with respect to the
acquisition of assets or properties to be used primarily for a business  purpose
within the scope of the business purpose of this Partnership  except as provided
in Sections 1.3 (a)(iii), (v) and (vi); provided,  however, that nothing in this
Agreement  will  restrict  the  Excluded  Ventures,  as  to  current  or  future
activities,  from owning,  acquiring,  developing or exploiting assets, projects
and/or  business  opportunities  of the type  described  in  Schedule  1.9(c) in
accordance  with the  current  terms of the  existing  contractual  arrangements
identified in Schedule  1.9(c) and reasonable  extensions or expansions  thereof
and provided that each Partner shall use its  reasonable  commercial  efforts to
conduct its  activities  so as not to frustrate  or interfere  with the business
purpose  of  the  Partnership.  This  provision  does  not  preclude  charitable
foundations  sponsored  by KM or Shell or their  Affiliates  from  receiving  or
holding  non-operated  property  rights  involved with  activities  described in
Section 1.3(a);  provided,  however, that no such transfers shall be made by the
Partnership to such charitable  foundations.  If KM or Shell or their respective
Affiliates  acquires  operating or actual control of another entity or assets of
another  entity  with CO2  related  assets  (e.g.,  pipelines  and/or CO2 source
fields--excluding  any oil and/or  natural gas  producing  property even if such
property  is  under  CO2  injection),  the  acquiring  company,  to  the  extent
permissible by existing legal or contractual obligations or restrictions,  shall
offer to sell or to contribute to the Partnership the equity or assets acquired,
to the extent the equity or assets are related to the  activities  described  in
Section 1.3(a) (subject to associated liabilities).  In exchange for such equity
or assets,  the acquiring  company shall receive an additional GP Interest or LP
Interest, as the case may be, having a value equal to the cost

                                       -6-
<PAGE>


to the  acquiring  company of such  equity or asset sold or  contributed  to the
Partnership. The cost to the acquiring company shall equal (i) the price paid by
the acquiring company for the equity or asset if the price was separately stated
or agreed  between the acquiring  company and the seller or (ii) the fair market
value of the CO2  related  equity or assets if the price  paid by the  acquiring
company is not separately  stated or the acquisition was part of an exploration,
production or other business  arrangement  that included  exchanges or trades of
economic interests in mineral properties.

     (d) To the extent  permitted  by  applicable  law and  except as  otherwise
provided in this Agreement, including Sections 1.9, 5.3 and 5.6 (c), the General
Partner,  when  acting on behalf of the  Partnership,  is hereby  authorized  to
purchase  property  from,  sell property to, or otherwise deal with any Partner,
acting on its own behalf,  or any  Affiliate of any Partner,  provided  that any
such purchase,  sale or other transaction shall be in the ordinary course of the
Partnership's  business and shall be made on terms and  conditions  which are no
less  favorable  to  the  Partnership  than  if the  sale,  purchase,  or  other
transaction had been entered into with an independent third party.

     (e) Except as  otherwise  provided  in Section  5.3,  each  Partner and any
Affiliate  thereof may also lend money to,  borrow money from,  act as a surety,
guarantor or endorser for, guarantee or assume one or more specific  obligations
of, provide  collateral  for, and transact  other business with the  Partnership
and,  subject to other  applicable law, has the same rights and obligations with
respect  thereto as a Person who is not a Partner,  provided  that, if a Partner
acts as  surety,  guarantor,  or  endorser  for a  Partnership  obligation,  the
Partnership shall enter into a separate  agreement with such Partner,  with such
agreement to be made on terms and conditions commercially reasonable taking into
consideration all relevant facts and circumstances  from time to time during the
term of any such agreement of financial guaranty or other financial support. The
existence of these  relationships  and acting in such capacities will not result
in the Limited  Partner being deemed to be  participating  in the control of the
business of the  Partnership  or otherwise  affect the limited  liability of the
Limited Partners.

     (f) The General  Partner shall dispose of any assets or operations that are
inconsistent with the purposes of Section 1.3. Such disposition shall be made as
soon as practical consistent

                                       -7-
<PAGE>


with obtaining reasonable value for such assets and operations. Such disposition
may be made to a Partner upon approval of all the remaining Partners.

     SECTION 1.10  Definitions.

     Capitalized  words and phrases used in this  Agreement  have the  following
meanings:

     "Act" means the Texas Revised Limited Partnership Act, as amended, modified
or supplemented from time to time (or any corresponding provisions of succeeding
law).

     "Adjusted  Capital  Account  Deficit"  means,  with  respect to any General
Partner or Interest  Holder,  the  deficit  balance,  if any,  in such  Interest
Holder's  Capital Account as of the end of the relevant  Allocation  Year, after
giving effect to the following adjustments:

         (i) Credit to such  Capital  Account  any  amounts  which such  General
Partner or Interest Holder is obligated to restore  pursuant to any provision of
this  Agreement  or is  deemed  to be  obligated  to  restore  pursuant  to  the
penultimate  sentences of Regulations Sections  1.704-2(g)(1) and 1.704-2(i)(5);
and

         (ii) Debit to such  Capital  Account  the items  described  in Sections
1.704-1(b)(2)(ii)(d)(4),  1.704-1(b)(2)(ii)(d)(5) and 1.704-1(b)(2)(ii)(d)(6) of
the Regulations. The foregoing definition of Adjusted Capital Account Deficit is

or Interest Holder's Capital Contributions adjusted as follows:

         (i)  Increased by the amount of any  Partnership  liabilities  that are

Partnership Property distributed to such Interest Holder;

                                       -8-
<PAGE>


         (ii) Increased by any amounts  actually paid by the General  Partner or
an  Interest  Holder  to any  Partnership  lender  pursuant  to the terms of any
Assumption Agreement; and

         (iii)  Reduced by the amount of cash and the Gross  Asset  Value of any
Partnership  Property  distributed to the General  Partner or an Interest Holder
and the amount of any  liabilities of the General  Partner or an Interest Holder
assumed by the  Partnership or which are secured by any property  contributed by
the General Partner or an Interest Holder to the  Partnership.  In the event the
General  Partner or any  Interest  Holder  transfers  all or any  portion of its
Interest in accordance  with the terms of this Agreement,  his transferee  shall
succeed to the Adjusted Capital  Contribution of the transferor to the extent it

                                       -12-
<PAGE>


interpreted  and applied in a manner  consistent with such  Regulations.  In the
event the  General  Partner  shall  determine  that it is  prudent to modify the
manner  in  which  the  Capital  Accounts,  or any  debits  or  credits  thereto
(including,  without limitation, debits or credits relating to liabilities which
are secured by contributions or distributed property or which are assumed by the
Partnership,  General Partner,  or Interest  Holders),  are computed in order to
comply with such  Regulations,  the General Partner may make such  modification,
provided that, to the extent any such modification would have a material adverse
effect on any  Limited  Partner  (in  either  timing of receipt or amounts to be
distributed  or the  character  or amount of taxable  income  recognized  by the
Limited Partner),  such  modification  shall require the consent of such Limited
Partner.  The General Partner also shall (i) make adjustments that are necessary
to maintain  equality  between the Capital  Accounts of the General  Partner and
Interest  Holders  and  the  amount  of  Partnership  capital  reflected  on the
Partnership's  balance sheet, as computed for book purposes,  in accordance with
Regulations  Section   1.704-1(b)(2)(iv)(q),   and  (ii)  make  any  appropriate
modifications  in the event  unanticipated  events  might  otherwise  cause this
Agreement not to comply with Regulations Section  1.704-1(b),  provided that, to

this Agreement and would have a material  adverse effect on any Limited Partner,
such adjustment shall require the consent of such Limited Partner.

     "Capital Additions and Improvements" shall mean expenditures for new items,
projects  or other  assets or  programs  that are made with the plan to  improve

delivery systems,  or otherwise to increase the deliverability of CO2 or related
services  (whether in the form of  acquisition or  construction  of additions or
improvements).  Where  expenditures  are  made  in part in  respect  of  Capital

good faith allocation thereof between the portion made for Capital Additions and
Improvements and the portion made for other purposes shall be conclusive.

Interest  Holder,  the amount of money and the initial  Gross Asset Value of any

traded on an  established  securities  market  and which is  contributed  to the
Partnership  by the maker of the note (or a Person  related  to the maker of the
note within the meaning of Regulations Section  1.704-1(b)(2)(ii)(c))  shall not
be included in the Capital Account of any Person until the  Partnership  makes a
taxable  disposition of the note or until (and to the extent) principal payments

1.704-1(b)(2)(iv)(d)(2).

     "Capital  Maintenance  Expenditures" shall mean those expenditures that are
not  Capital  Additions  and  Improvements  and that  relate  to  improving  the
efficiency or lowering the cost of operations or  maintaining  (and that are not
designed  to  expand)  the  existing  capacity,  deliverability,  production  or
reserves of the Partnership  (whether in the form of acquisition or construction
of additions or improvements). Where expenditures are made in part in respect of
Capital  Maintenance  Expenditures  and in part for other purposes,  the General
Partner's  good faith  allocation  thereof  between the portion made for Capital
Maintenance  Expenditures  and the  portion  made for  other  purposes  shall be
conclusive.

federal income tax purposes with respect to an asset for such  Allocation  Year,
except that if the Gross Asset Value of an asset differs from its adjusted basis
for  federal  income tax  purposes at the  beginning  of such  Allocation  Year,
Depreciation  shall be an amount  which  bears the same ratio to such  beginning
Gross Asset Value as the federal income tax depreciation, amortization, or other
cost  recovery  deduction  for such  Allocation  Year  bears  to such  beginning
adjusted tax basis;  provided,  however,  that if the adjusted basis for federal
income tax  purposes of an asset at the  beginning  of such  Allocation  Year is
zero,  Depreciation  shall be determined  with reference to such beginning Gross
Asset Value using any

                                       -14-

reasonable  method  selected by the  General  Partner  and  consistent  with the

(computed  from  time to time)  multiplied  by the  total  of all  distributions
(including  the Initial  Adjustment  Amounts) made to all Partners for the first
sixteen Fiscal Quarters of the  Partnership.  For purposes of computing both (i)
and (ii) and any computation at any time of a Distribution  Imbalance  Amount or
Distribution  Imbalance  Distribution,  the  Initial  Adjustment  Amount of each
Partner  shall  be  treated  as if it had been  received  by such  Partner  as a
distribution made on the date of the first  distribution made by the Partnership
to any  Partner.  A  Partner  will be deemed  to have a  "Positive  Distribution
Imbalance"  to  the  extent  (i)  exceeds  (ii)  and  a  "Negative  Distribution
Imbalance" to the extent (ii) exceeds (i).

made to any Partner  during Fiscal  Quarters  seventeen  through  twenty-four in
order to eliminate a Negative  Distribution  Imbalance for such Partner.  To the
extent of applicable Available Cash From Operations, each quarterly Distribution
Imbalance  Distribution  during Fiscal Quarters  seventeen through  twenty-three
shall  equal  one  eighth  of such  Partner's  Negative  Distribution  Imbalance
computed  as of the  beginning  of the  seventeenth  quarter.  The  Distribution
Imbalance Distribution for the twenty-fourth Fiscal Quarter shall be computed as
the amount necessary to be distributed so as to cause (i) the Net Present Value,
of all  distributions  actually  made to such Partner for the first  twenty-four
Fiscal Quarters to equal (ii) the Net Present Value, of such Partner's  Interest
(computed from time to time) multiplied by the total of all  distributions  made
to all Partners for the first twenty-four Fiscal Quarters of the Partnership.

may request that the  activities  and assets  related to the  Voluntary  Capital
Contribution be distributed in kind to them. Upon any such in kind  distribution
the Partnership  shall, if requested to do so by the Partners  participating  in
the distributed activity,  continue to provide services at cost to such Partners
for such activity under the terms of a mutually agreeable service agreement.  If
KM proposes an activity in which the other Partners do not elect to participate,
KM shall be authorized to conduct such activity as an activity separate from the
Partnership,  in  accordance  with a  non-competition  agreement  or such  other
arrangements  reasonably  requested  by  the  General  Partner  to  protect  the

activity.  Any Partner that fails to contribute its share of a Voluntary Capital
Contribution after having consented to do so shall be deemed a Defaulted Partner
with  respect  to it  share  of such  Voluntary  Capital  Contribution  plus any
additional Partnership expenses caused by such default including attorneys fees,
costs or interest on funds used in  substitution  for such  Defaulted  Partners'
Voluntary Capital Contribution.  The Partnership shall be authorized to withhold
all  distributions of cash or other property to such Defaulting  Partner,  until

Defaulted Partner's Voluntary Capital Contribution and other reasonable fees and
expenses  (with all such  amounts in the  aggregate  referred  to as  "Defaulted
Voluntary  Amount") plus an additional 150% of such Defaulted  Voluntary Amount.

authorized to seek any additional remedy at law or in equity with respect to the
unpaid amount of such Defaulted  Voluntary Amount, plus all costs of collection,
including  reasonable  attorneys' fees and other expenses.  Notwithstanding  the
foregoing,  the  General  Partner  may,  with  the  unanimous  agreement  of the
Partners,  cause a  reevaluation  of the  Partnership  if in the  opinion of the
General  Partner,  the  variation  in the  ownership  caused by the failure of a
Partner to participate  in a Voluntary  Capital  Contribution  is more than five
percent (5%).

Contributions  (whether  pursuant to Section  2.3(a) or (b),  Section  1.9(c) or
otherwise),  each Partner shall have the preemptive  right to make an additional
Capital  Contribution  in an amount that will maintain such  Partner's  relative
interest in the  Partnership  (in comparison to all other  Partners) in the same
ratio

that existed prior to such additional Capital Contribution.  This right shall be
deemed  to be  waived  by any  Partner  who does not  exercise  it and make such
Capital  Contribution  at the time  established by the General  Partner for such
additional  Capital  Contribution to be received by the Partnership (but upon at
least thirty (30) days' advance notice thereof).  No interest in the Partnership
shall be sold by the Partnership to or Capital Contribution received or accepted
from any person other than KM or Shell or their  respective  Affiliates,  unless
unanimously approved in writing by the Partners.

     (d) Any Partner  shall have the right to  participate,  up to the amount of
its pro rata share based on its Interest,  in any Capital  Contribution in order
to maintain  its pro rata  interest  in the  Partnership;  provided  that once a
Partner has declined to participate in a Voluntary Capital  Contribution request
or has defaulted in its obligation to pay a Mandatory Capital Contribution, such
Partner  shall have no other right to  contribute  capital  with respect to such
Capital Contribution and such  nonparticipating  Partner will suffer dilution of
its interest in the Partnership and such other remedies as provided  herein.  If
one or more Partners  should  contribute cash or other assets to the Partnership
and receive an  additional  interest in the  Partnership  or if a new Partner is
admitted to the Partnership, the noncontributing Partner shall have 30 days from
the  date of  notice  of the  Partner's  contribution,  in  which to make a cash
contribution  to the  Partnership  in an amount as required  for such Partner to
maintain  its pro rata  interest  in the  Partnership.  After  30 days,  the non
contributing  Partner  shall have no other right to make an  additional  Capital
Contribution  with  respect to such  capital  contribution  by the  contributing
Partner.

     SECTION 2.4  Other Matters.

     (a) Except as otherwise  provided in this Agreement or in the Act,  neither
the General  Partner nor the Interest Holder shall demand or receive a return of
his Capital  Contributions or withdraw from the Partnership  without the consent
of  all  Partners.  Under  circumstances  requiring  a  return  of  any  Capital
Contributions,  no General  Partner or Interest  Holder  shall have the right to
receive property other than cash except as may be specifically provided herein.

     (b) Neither the General  Partner nor the Interest  Holder shall receive any
interest,  salary or drawing  with respect to his Capital  Contributions  or his
Capital Account or for services rendered

                                       -33-

on behalf of the Partnership or otherwise in his capacity as the General Partner
or Interest Holder, except as otherwise provided in this Agreement.

     (c)  Provided  that  the  Limited  Partners  act in  accordance  with  this
Agreement and except as otherwise provided by an Assumption and  Indemnification
Agreement,  no  Limited  Partner  shall be liable  for the  debts,  liabilities,
contracts,  or any other  obligations  of the  Partnership.  Except as otherwise
provided by any other agreements  among the Partners or mandatory  provisions of
applicable state law, a Limited Partner shall be liable only to make his Capital
Contributions  set forth in Sections 2.2 and 2.3(a) and shall not be required to
lend any funds to the Partnership or, after such Capital Contributions have been
made, to make any additional Capital Contributions to the Partnership.

     (d) The  General  Partner  shall not have any  personal  liability  for the
repayment of any Capital Contributions of any Interest Holder.

     (e)  Notwithstanding  any contrary provision herein, to the extent that any
Partnership  Property contributed by the General Partner or the Limited Partners
is determined to be productive of hydrocarbons, or other minerals other than CO2
the Partnership  shall  immediately upon request of the Partner that contributed
such property make an assignment to such contributing Partner of all interest in
such  hydrocarbons  or other minerals other than CO2. Such  assignment  shall be
made at no cost to the  contributing  Partner  and  shall be  deemed  to have no
effect on the Capital Accounts or other accounts of any Partner. Such assignment
shall include those  geological  strata,  features,  zones,  structures or other
described  areas as  identified  as  productive  or  potentially  productive  of
hydrocarbons  or other  minerals  other than CO2, but shall not include any bore
hole,  subsurface  or  surface  equipment  used  in the  production,  gathering,
transportation or other activities for the Partnership's CO2 related activities.
Nothing in this Section 2.4 (e) shall require the  Partnership to dispose of (a)
any interests it earns in other  mineral  properties  as  consideration  for the
provision by the  Partnership of CO2 product or services to third parties or any
interest the  Partnership  holds or later  acquires in the West Brahaney unit or
the Mid Cross unit.

     (f) If Available Cash From Operations  with respect to the  distribution to
be made for the  twenty-fourth  Fiscal Quarter is insufficient to distribute the
full amount of the  Distribution  Imbalance  Distribution so as to eliminate all
Distribution  Imbalance Amounts for all Partners,  any Partner having a Positive
Distribution   Imbalance  shall  be  required  to  make  an  additional  Capital
Contribution in the amount of such Partner's Positive Distribution Imbalance and
such funds shall be added to Available Cash From  Operations and  distributed to
the Partner's having Negative  Distribution  Imbalance Amounts.  Such additional
Capital  Contributions shall be considered to be Mandatory Capital Contributions
and  shall be made  within  thirty  (30) days  after  the end of Fiscal  Quarter
twenty-four.

                                   ALLOCATIONS

     SECTION 3.1  Profits.

     Profits for any Allocation  Year shall be allocated in the following  order
and priority:

     (a) First in accordance  with the special  allocations set forth in Section
3.3 and 3.4,  including  without  limitation  the  allocations  with  respect to
Priority  Distributions  and Distribution  Imbalance  Distributions  provided in
Section 3.3 (h);

     (b) One  hundred  percent  (100%) to the  General  Partner to the extent of
losses  allocated  to the General  Partner  pursuant to Section  3.2(a),  to the
extent  not offset by prior  allocations  of Profits  pursuant  to this  Section
3.1(b);

     (c) To the General  Partner and all  Interest  Holders in  accordance  with
their  Interests  in an  amount  equal  to the  remainder,  if  any,  of (i) the
cumulative  Losses  allocated  pursuant  to  Section  3.2(b)(i)  for  all  prior
Allocation  Years, over (ii) the cumulative  Profits allocated  pursuant to this
Section 3.1(c) for all prior Allocation Years; and


                                       -35-
<PAGE>


     (d) The balance, if any, to the General Partner and all Interest Holders in
accordance with the ratio that such Partners received distributions,  other than
Priority  Distributions  or Distribution  Imbalance  Distributions,  during such
Fiscal Year.

     SECTION 3.2  Losses.

     After giving  effect to the special  allocations  set forth in Sections 3.3
and 3.4,  Losses  for any  Allocation  Year shall be  allocated  as set forth in
Section 3.2(a) and (b), subject to the limitation in Section 3.2(c).

     (a) During the first sixteen Fiscal  Quarters and for so long thereafter as
a  Distribution  Imbalance  Amount  exists,  all Losses shall be  allocated  one
hundred percent (100%) to the General Partner.

     (b) Except as provided in Section 3.2 (a),  Losses for any Allocation  Year
shall be allocated in the following order and priority:

         (i)  First,  to  the  General  Partner  and  all  Interest  Holders  in
accordance with their Interests in an amount equal to the remainder,  if any, of
(i) the cumulative  Profits  allocated  pursuant to Section 3.1(c) for all prior
Allocation  Years,  over (ii) the cumulative  Losses allocated  pursuant to this
Section 3.2(b)(i) for all prior Allocation Years; and

         (ii) The  balance,  if any,  to the General  Partner  and all  Interest
Holders in accordance with their Interests.
     (c) The Losses  allocated  pursuant  to Section  3.2(a) and Section 3.2 (b)
shall not exceed the maximum  amount of Losses that can be so allocated  without
causing any Interest  Holder to have an Adjusted  Capital Account Deficit at the
end of any  Allocation  Year.  In the  event  some  but not all of the  Interest
Holders  would have Adjusted  Capital  Account  Deficits as a consequence  of an
allocation  of Losses  pursuant  to Section  3.2(a)  and  Section  3.2 (b),  the
limitation  set forth in this  Section  3.2(c)  shall be applied on an  Interest
Holder by Interest Holder basis so as to allocate the maximum permissible Losses
to each Interest Holder under Section 1.704-1(b)(2)(ii)(d) of the

                                       -36-
<PAGE>


Regulations.  All Losses in excess of the  limitations set forth in this Section
3.2(c) shall be allocated to the General Partner.

     SECTION 3.3  Special Allocations.

     The following special allocations shall be made in the following order:

     (a)  Minimum  Gain  Chargeback.  Except as  otherwise  provided  in Section
1.704-2(f)  of the  Regulations,  notwithstanding  any other  provision  of this
Article III, if there is a net decrease in  Partnership  Minimum Gain during any
Allocation  Year,  the General  Partner and  Interest  Holder shall be specially
allocated items of Partnership income and gain for such Allocation Year (and, if
necessary,  subsequent  Allocation  Years) in an amount  equal to such  Person's
share of the net decrease in Partnership Minimum Gain,  determined in accordance
with  Regulations  Section  1.704-2(g).  Allocations  pursuant  to the  previous
sentence  shall be made in proportion to the respective  amounts  required to be
allocated to the General Partner and Interest Holder pursuant thereto. The items
to be so allocated shall be determined in accordance with Sections 1.704-2(f)(6)
and 1.704-2(j)(2) of the Regulations.  This Section 3.3(a) is intended to comply
with the  minimum  gain  chargeback  requirement  in Section  1.704-2(f)  of the
Regulations and shall be interpreted consistently therewith.

     (b)  Partner  Minimum  Gain  Chargeback.  Except as  otherwise  provided in
Section 1.704-2(i)(4) of the Regulations, notwithstanding any other provision of
this Article III, if there is a net decrease in Partner Nonrecourse Debt Minimum
Gain attributable to a Partner Nonrecourse Debt during any Allocation Year, each
Person who has a share of the Partner Nonrecourse Debt Minimum Gain attributable
to  such  Partner  Nonrecourse  Debt,  determined  in  accordance  with  Section
1.704-2(i)(5)  of  the  Regulations,  shall  be  specially  allocated  items  of
Partnership  income  and gain for  such  Allocation  Year  (and,  if  necessary,
subsequent  Allocation  Years) in an amount equal to such Person's  share of the
net  decrease in Partner  Nonrecourse  Debt Minimum  Gain  attributable  to such
Partner  Nonrecourse  Debt,  determined in accordance with  Regulations  Section
1.704-2(i)(4).  Allocations  pursuant to the previous  sentence shall be made in
proportion  to the  respective  amounts  required to be allocated to the General
Partner and Interest Holder pursuant

                                       -37-
<PAGE>


thereto.  The items to be so allocated  shall be determined  in accordance  with
Sections 1.704-2(i)(4) and 1.704-2(j)(2) of the Regulations. This Section 3.3(b)
is intended to comply with the minimum gain  chargeback  requirement  in Section
1.704-2(i)(4)   of  the  Regulations  and  shall  be  interpreted   consistently
therewith.

     (c) Qualified Income Offset. In the event any Interest Holder  unexpectedly
receives any adjustments,  allocations,  or  distributions  described in Section
1.704-1(b)(2)(ii)(d)(4),     Section    1.704-1(b)(2)(ii)(d)(5)    or    Section
1.704-1(b)(2)(ii)(d)(6) of the Regulations, items of Partnership income and gain
shall be  specially  allocated  to each such  Interest  Holder in an amount  and
manner sufficient to eliminate,  to the extent required by the Regulations,  the
Adjusted Capital Account Deficit of such Interest Holder as quickly as possible,
provided that an allocation  pursuant to this Section  3.3(c) shall be made only
if and to the extent that such  Interest  Holder would have an Adjusted  Capital
Account  Deficit  after all other  allocations  provided for in this Article III
have been tentatively made as if this Section 3.3(c) were not in the Agreement.

     (d) Gross Income Allocation. In the event any Interest Holder has a deficit
Capital  Account at the end of any Allocation Year which is in excess of the sum
of (i) the amount such Interest  Holder is obligated to restore  pursuant to any
provision of this Agreement,  and (ii) the amount such Interest Holder is deemed
to be obligated to restore pursuant to the penultimate  sentences of Regulations
Sections  1.704-2(g)(1)  and  1.704-2(i)(5),  each such Interest Holder shall be
specially  allocated items of Partnership  income and gain in the amount of such
excess as quickly as  possible,  provided  that an  allocation  pursuant to this
Section 3.3(d) shall be made only if and to the extent that such Interest Holder
would  have a  deficit  Capital  Account  in  excess of such sum after all other
allocations provided for in this Article III have been made as if Section 3.3(c)
and this Section 3.3(d) were not in the Agreement.

     (e) Partner Nonrecourse Deductions.  Any Partner Nonrecourse Deductions for
any  Allocation  Year shall be  specially  allocated  to the General  Partner or
Interest  Holder who bears the economic risk of loss with respect to the Partner
Nonrecourse Debt to which such Partner  Nonrecourse  Deductions are attributable
in accordance with Regulations Section 1.704-2(i)(1).

                                       -38-
<PAGE>


     (f) Nonrecourse Deductions.  Nonrecourse Deductions for any Allocation Year
shall be specially  allocated to the General Partner and all Interest Holders in
accordance with their Interests.

     (g) Section 754  Adjustments.  To the extent an  adjustment to the adjusted
tax basis of any  Partnership  asset  pursuant  to Code  Section  734(b) or Code
Section    743(b)    is    required,    pursuant    to    Regulations    Section
1.704-1(b)(2)(iv)(m)(2)  or Regulations Section  1.704-1(b)(2)(iv)(m)(4),  to be
taken  into  account  in  determining  Capital  Accounts  as  the  result  of  a
distribution to a General Partner or Interest Holder in complete  liquidation of
his  interest  in the  Partnership,  the  amount of such  adjustment  to 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
gain or loss  shall  be  specially  allocated  to the  General  Partner  and the
Interest  Holders in accordance  with their  interests in the Partnership in the
event  that  Regulations  Section  1.704-1(b)(2)(iv)(m)(2)  applies,  or to  the
General  Partner or Interest  Holder to whom such  distribution  was made in the
event that Regulations Section 1.704-1(b)(2)(iv)(m)(4) applies.

     (h) Priority  Distribution  Allocations.  All or a portion of the remaining
items of Partnership income or gain, if any, shall be specially allocated to the
General  Partner and Interest  Holders in proportion to and to the extent of the
remainder,   if  any,  of  (i)  the  total  of  all  Priority  Distributions  or
Distribution Imbalance Distributions of such General Partner and Interest Holder
has received  pursuant to Sections  4.1(a)(i),  4.1(b)(i) or 4.2 (a)(i) from the
commencement of the Partnership to a date thirty (30) days after the end of such
Allocation  Year, over (ii) the cumulative items of income and gain allocated to
such General  Partner or Interest Holder pursuant to this Section 3.3(h) for all
prior Allocation Years.

     (i) Allocations Relating to Taxable Issuance of Partnership Interests.  Any
income,  gain, loss or deduction  realized as a direct or indirect result of the
issuance of an interest by the  Partnership to a Partner (the "Issuance  Items")
shall be allocated  among the General  Partner and Interest  Holders so that, to
the extent  possible,  the net amount of such Issuance Items,  together with all
other  allocations  under this  Agreement  to the General  Partner and  Interest
Holder, shall be equal

                                       -39-
<PAGE>


to the net amount that would have been  allocated to each such  General  Partner
and Interest Holder if the Issuance Items had not been realized.

     (j) For purposes of Section 613A(c)(7)(D) of the Code, basis allocation for
oil and gas property  contributed  by Shell will be equal to (a) such  Partner's
contribution to the adjusted tax basis in each property, and (b) non-contributed
property in accordance with the Interests of the Partners.

     (k) As  provided in Section  1.704-1(b)(4)(v)  of the  Regulations,  amount
realized  for an oil and gas property  shall be  allocated  as follows:  (a) for
contributed  property  (i) an amount that  represents  a recovery  of  simulated
depletion basis on contributed property is allocated to the Partners in the same
proportion  as the  remaining  balance in the  Section  704(c)  Account for that
property is allocated to the Partners, and (ii) any remaining amount realized is
allocated  so as to cause the  capital  account  ratios of the  Partners to most
likely   equal  the   ratio  of  their   respective   Interests;   and  (b)  for
non-contributed property in accordance with the Partners Interest.

     (l) Any  recapture of  depreciation,  intangible  drilling and  development
costs, or any other item of deduction or credit shall,  to the extent  possible,
be  allocated  among  the  Partners  in  accordance  with  their  share  of  the
depreciation,  intangible  drilling  and  development  costs,  or other  item of
deduction or credit which is recaptured.

     (m) Any  recapture  of  depletion  shall  be  computed  separately  by each
Partner,  in accordance with its depletion allowance computed in accordance with
this Agreement.

     (n)  Section  43  credits  relating  to CO2 of  Shell  and  its  Affiliates
contributed  properties  (upon initial  formation of the  Partnership)  shall be
allocated  to Shell and  Section 43 credits  relating  to CO2 of KM  contributed
properties (upon initial formation of the Partnership) shall be allocated to KM.
All  other  Section  43  credits  shall  be  allocated  in  accordance  with the
Interests.

     (o) Section 29 credits  from Shell  contributed  properties  (upon  initial
formation of the Partnership) shall be allocated to Shell and Section 29 credits
from KM contributed properties

                                       -40-
<PAGE>


(upon initial formation of the Partnership)  shall be allocated to KM. All other
Section 29 credits shall be allocated in accordance with the Interests.

     (p) To the extent that any  adjustment  is made to the Profits  allocations
made pursuant to Section  3.3(h) such that a KM obligation  arises under Section
5.5 (i), KM shall be specially allocated items of Partnership income and gain as
quickly as possible  consistent  with  compliance  with  applicable  law, in the
amount necessary to reverse such adjustment.

     SECTION 3.4  Curative Allocations.

     The allocations set forth in Sections 3.2(b)(i),  3.3(a),  3.3(b),  3.3(c),
3.3(d), 3.3(e),  3.3(f), and 3.3(g) (the "Regulatory  Allocations") are intended
to comply with certain requirements of the Regulations.  It is the intent of the
Partners  that, to the extent  possible,  all  Regulatory  Allocations  shall be
offset either with other Regulatory  Allocations or with special  allocations of
other items of  Partnership  income,  gain,  loss or deduction  pursuant to this
Section 3.4. Therefore,  notwithstanding any other provision of this Article III
(other than the  Regulatory  Allocations),  the General  Partner shall make such
offsetting special allocations of Partnership income, gain, loss or deduction in
whatever  manner  it  determine  appropriate  so  that,  after  such  offsetting
allocations  are made,  the General  Partner's  and  Interest  Holder's  Capital
Account balance is, to the extent possible, equal to the Capital Account balance
such  General  Partner  or  Interest  Holder  would  have had if the  Regulatory
Allocations  were not  part of the  Agreement  and all  Partnership  items  were
allocated  pursuant to Sections  3.1,  3.2(a),  and 3.3(h).  In  exercising  its
discretion  under this Section 3.4, the General  Partner shall take into account
future Regulatory  Allocations  under Sections 3.3(a) and 3.3(b) that,  although
not yet made, are likely to offset other Regulatory  Allocations previously made
under Sections 3.3(e) and 3.3(f).


                                       -41-
<PAGE>


     SECTION 3.5  Other Allocation Rules.

     (a) Profits,  Losses and any other items of income, gain, loss or deduction
shall be allocated to the Partners and Interest Holders pursuant to this Article
III as of the last day of each Fiscal Year;  provided that  Profits,  Losses and
such other items shall also be allocated at such times as the Gross Asset Values
of  Partnership  Property  are  adjusted  pursuant to  subparagraph  (ii) of the
definition of Gross Asset Value in Section 1.10.

     (b) For purposes of  determining  the Profits,  Losses,  or any other items
allocable  to any  period,  Profits,  Losses,  and any such other items shall be
determined  on a daily,  monthly,  or other basis,  as determined by the General
Partner using any permissible  method under Code Section 706 and the Regulations
thereunder.

     (c) All  allocations  to the  Interest  Holders  pursuant to this Section 3
shall, except as otherwise provided,  be divided among them in proportion to the
Interests held by each. In the event there is more than one General Partner, all
such allocations to the General Partners shall be divided among them as they may
agree.

     (d)  The  Partners  are  aware  of  the  income  tax  consequences  of  the
allocations  made by this  Article  III and  hereby  agree  to be  bound  by the
provisions of this Article III in reporting  their shares of Partnership  income
and loss for income tax  purposes,  except to the extent  otherwise  required by
law.

     (e) Solely for purposes of  determining  a Partner's  or Interest  Holder's
proportionate share of the "excess  nonrecourse  liabilities" of the Partnership
within the meaning of  Regulations  Section  1.752-3(a)(3),  the  Partners'  and
Interest  Holders'  interests in  Partnership  profits are initially as follows:
General  Partner two percent (2%),  and Interest  Holders  ninety-eight  percent
(98%) (in proportion to their Interests).

     (f) To the extent  permitted by Section  1.704-2(h)(3)  of the Regulations,
the General Partner shall endeavor to treat distributions of Available Cash From
Operations or Available Cash

                                       -42-
<PAGE>


From  Sales  or  Refinancings  as  having  been  made  from  the  proceeds  of a
Nonrecourse Liability or a Partner Nonrecourse Debt only to the extent that such
distributions  would not cause or increase an Adjusted  Capital  Account Deficit
for any Interest Holder.

     SECTION 3.6  Tax Allocations:  Code Section 704(c).

     In  accordance  with Code Section  704(c) and the  Regulations  thereunder,
income,  gain,  loss, and deduction with respect to any property  contributed to
the capital of the  Partnership  shall,  solely for tax  purposes,  be allocated
among the General  Partner  and  Interest  Holders so as to take  account of any
variation  between the adjusted  basis of such property to the  Partnership  for
federal  income tax  purposes  and its initial  Gross Asset Value  (computed  in
accordance  with  subparagraph  (i) of the  definition of "Gross Asset Value" in
Section 1.10.

     In the event the Gross  Asset  Value of any  Partnership  asset is adjusted
pursuant  to  subparagraph  (ii) of the  definition  of "Gross  Asset  Value" in
Section 1.10,  subsequent  allocations of income, gain, loss, and deduction with
respect to such asset shall take account of any  variation  between the adjusted
basis of such asset for federal income tax purposes and its Gross Asset Value in
the same manner as under Code Section 704(c) and the Regulations thereunder.

     Any elections or other decisions relating to such allocations shall be made
by the General  Partner in any manner that  reasonably  reflects the purpose and
intention of this Agreement,  provided that the Partnership shall elect to apply
a  'functional  allocation'  of the  actual  tax items  (e.g.  depreciation  and
depletion)  related to each Partnership  Property to the Partner who contributed
such  Partnership  Property to the Partnership or such other  allocation  method
permitted  by the  Regulations  under  Code  Section  704(c)  that  most  nearly
accomplishes the 'functional  allocation'.  Allocations pursuant to this Section
3.6 are solely for  purposes  of federal,  state,  and local taxes and shall not
affect,  or in any way be taken into account in computing,  any Person's Capital
Account or share of Profits,  Losses, other items, or distributions  pursuant to
any provision of this Agreement.


                                       -43-
<PAGE>


     Except as otherwise  provided in this  Agreement,  all items of Partnership
income, gain, loss, deduction,  and any other allocations not otherwise provided
for shall be divided  among the Partners in the same  proportions  as they share
Profits or Losses, as the case may be, for the Allocation Year.

                                   ARTICLE IV
                                  DISTRIBUTIONS

     SECTION 4.1  Available Cash From Operations.

     Except  as  otherwise   provided  in  Article  XII,   Available  Cash  From
Operations,  if any, shall be distributed not later than the thirtieth day after
the end of each Fiscal Quarter in the following order and priority:

     (a) During the first sixteen Fiscal Quarters of the Partnership:

         (i)  First,   to  KM,  an  amount   equal  to  the
Priority Distribution; and

         (ii)  Second,  all  remaining  Available  Cash From  Operations  to the
         General Partner and to the Interest  Holders other than KM in the ratio
         that each such Partner's Capital Contribution bears to the total of the
         Capital Contributions of all
         the Partners other than KM.

     (b) For Fiscal Quarters seventeen through twenty-four:

         (i) First,  the  Distribution  Imbalance  Distributions to  the General
         Partner  and   all   Interest   Holders  with   Negative   Distribution

     SECTION 4.4  Amounts Withheld.

     All amounts withheld or required to be withheld pursuant to the Code or any

                                   MANAGEMENT

     SECTION 5.1  Authority of the General Partner.

     Subject to the  limitations  and  restrictions  set forth in this Agreement
(including,  without limitation, those set forth in this Article V), the General
Partner shall direct the business and affairs of the Partnership and in so doing
shall  manage,  control  and have all of the  rights  and  powers  which  may be
possessed  by general  partners  under the Act.  At the sole  discretion  of the
General  Partner,  the General Partner may from time to time delegate all or any
portion  of its  authority  to act on behalf of the  Partnership  to one or more
persons who shall have such duties,  titles, and authorities as may be delegated
by the General  Partner.  Such persons may be referred to using titles,  such as
the Partnership's "Director",  "President", "Vice President", "Manager" or other
titles,  commonly  associated with entities formed as  corporations.  The use of
such titles is for convenience and shall

                                       -46-
<PAGE>


not be deemed to create  any  inference  that the  Partnership  or its  Partners
intend for the  Partnership  to be  considered  for any  purpose to be an entity
treated as a corporation.

     In the event more than one Person  acquires  the  interest  of the  General
Partner,  the  rights  and  powers of the  General  Partner  hereunder  shall be
exercised  by them in such  manner  as they  may  agree.  In the  absence  of an
agreement among the General  Partners,  no General Partner shall exercise any of
such rights and powers without the unanimous consent of all General Partners.

     SECTION 5.2  Right to Rely on General Partner.

     (a) Any Person  dealing  with the  Partnership  may rely  (without  duty of
further inquiry) upon a certificate signed by any General Partner as to:

         (i)  The  identity of any  General  Partner or any
Limited Partner;

         (ii)  The  existence  or  nonexistence  of  any  fact  or  facts  which
constitute a condition  precedent  to acts by a General  Partner or which are in
any other manner germane to the affairs of the Partnership;

         (iii) The  Persons  who are  authorized  to  execute  and  deliver  any
instrument or document of the Partnership; or

         (iv) Any act or failure to act by the  Partnership  or any other matter
whatsoever involving the Partnership or any Partner.

     (b) The signature of the General  Partner shall be necessary and sufficient
to convey  title to any  property  owned by the  Partnership  or to execute  any
promissory notes, trust deeds, mortgages, or other instruments of hypothecation,
and all of the Partners  agree that a copy of this Agreement may be shown to the
appropriate  parties in order to confirm the same,  and  further  agree that the
signature of any General  Partner shall be sufficient to execute any  "statement
of  partnership"  or other  documents  necessary to effectuate this or any other
provision of this

                                       -47-

and not allowing funds or other assets of the  Partnership to be commingled with
the funds or other assets of, held by, or registered in the name of, any General

borrowing by the General Partner or its Affiliates),  (ii) maintaining books and
financial  records  of the  Partnership  separate  from the books and  financial
records of any General Partner and its Affiliates, and observing all Partnership

limited  partnership and its  qualification to do business under the laws of the
State  of Texas  and of each  other  jurisdiction  in which  such  existence  or
qualification  is  necessary  to protect  the limited  liability  of the Limited
Partners or to enable the  Partnership  to conduct  the  business in which it is
engaged or to perform its obligations or exercise its rights under any agreement
to which it is a party  and (ii)  for the  accomplishment  of the  Partnership's
purposes,  including  the  acquisition,  management,  development,  maintenance,
preservation,  and  operation of  Partnership  Property in  accordance  with the
provisions  of this  Agreement  and  applicable  laws and  regulations.  Without
limitation of the foregoing, the General

                                       -50-
<PAGE>


Partner  shall  cause  the  Partnership  to  maintain  all  licenses,   permits,
registrations,  authorizations, use agreements, consents, orders or approvals of
governmental or  quasi-governmental  agencies and authorities  (whether federal,
state,  local,  municipal  or foreign)  necessary to own its  properties  and to
conduct  its  activities  in  accordance  with  all  applicable   laws,   rules,
regulations  and  orders,  except  where any  failure  to do so would not have a
Material Adverse Effect.

     (c) Unless otherwise agreed in writing by the Majority of the Partners, the
Partnership shall not maintain separate  insurance for the assets and operations
of the Partnership  other than the insurance  coverage obtained by Shell for the
benefit of the  Partnership  the cost of which shall be paid by the  Partnership
and the  coverage  of  which  is  generally  described,  as of the  date of this
Agreement,  to have a deductible or retention amount of $1,000,000 and a maximum

or claim  incurred  by reason of any act or  omission  performed  by the General
Partner in good faith in furtherance of the Partnership's business, specifically
including  such person's  sole,  partial or concurrent  negligence.  The General
Partner shall only be responsible for loss,  damage or claims incurred by reason
of  the  General  Partner's  (i)  gross  negligence,   (ii)  willful  or  wanton
misconduct,  (iii)  fraud,  (iv) willful  breach of duties,  or (v) bad faith or
reckless  disregard  of duty.  Additionally,  to the extent  that a conflict  of
interest  arising between the General  Partner,  or any Affiliate of the General
Partner,  on the one hand and a Limited Partner, or the Partnership on the other
hand, the General  Partner shall resolve such conflict  considering the relative
interest of each party to such conflict, including its own interest, and resolve
such  conflict  in a manner  which is in keeping  with  customary  and  accepted
industry practices and which is not outside the range of comparable arms' length
transactions involving nonaffiliated parties.

     (f) By executing this Agreement, each Partner has consented to and approved
the initial  five-year  Operating Budget. On or before October 1st of each year,
the General  Partner  shall  present to the Partners for  unanimous  approval an
update of the five-year Operating Budget for the forthcoming year (and including
the new fifth year to be added to such five-year rolling Operating  Budget).  If
the  unanimous  agreement of the Partners  cannot be reached on an update to the
Operating Budget,  then the most recent approved five-year Operating Budget will
remain  unchanged for the forthcoming  year and thereafter.  As provided in this
Agreement, the General Partner (including its officers and employees) shall have
authority to conduct the day-to-day affairs of the Partnership,  and the General
Partner will use its best efforts to conduct such affairs in a manner consistent
with the five-year Operating Budget that has been approved by the Partners.  All
changes and updates to the five-year  rolling Operating Budget shall require the
unanimous  approval of the Partners;  provided however the General Partner shall
have the unilateral  right to amend the Operating Budget (i) for any Fiscal Year
so long as such amendments do not increase any Operating Budget category by more
than fifteen  percent (15%) for any Fiscal Year or increase the total  Operating
Budget for any Fiscal Year by more than  fifteen  percent  (15%) or (ii) to make
expenditures as required to address any emergency situation. For this purpose an
emergency  situation is an unplanned  expenditure  that does not  constitute  an
ordinary  Capital  Maintenance  Expenditure  but that is  required  to correct a
condition  or to respond to an event or  occurrence  that has resulted in a loss
or, if not  addressed  is  reasonably  foreseen  to result in a loss,  damage or
destruction of property or injury to natural persons.

     (c) Unless  otherwise  provided  by Section  5.5(f) and  subject to Section
5.5(h),  in the event of any action by a Limited  Partner  against  any  General

     (f) Sections 5.5(a),  5.5(b),  5.5(c), 5.5(d), and 5.5(e) shall be enforced
only to the maximum extent  permitted by law and no Partner shall be indemnified
from any liability for fraud, bad faith, willful misconduct, or gross negligence
of itself or any of its Affiliates.

     (g) All  indemnities  provided  for in this  Agreement  shall  survive  the
transfer of a Partner's Interest.

     (h) Indemnification Procedures.

         (i) In the event any claim is made by a third party against any Partner
or Liquidator or any officer or successor or assign of any of them (each of them
being  referred to as an  "Indemnitee"),  with respect to an actual or potential
liability  for which any such Person is  otherwise  entitled  to be  indemnified
under any provisions of Sections 5.5(a),  5.5(b), 5.5(c), 5.5(d) or 12.8(c), and
any such Person wishes to be indemnified with respect thereto, such Person shall
promptly  notify the  Partnership,  its receiver or trustee (the  "Indemnitor");
provided that the failure of any such Person to notify any Indemnitor  shall not
relieve such  Indemnitor  from any liability which it otherwise may have to such
Person  hereunder,  except to the extent the  Indemnitor is able to  demonstrate
that its ability to defend such matter was prejudiced by such delay.

         (ii) Each  Indemnitee may by notice to the  Indemnitor  take control of
all aspects of the  investigation  and defense of all claims asserted against it
and may  employ  counsel of its  choice  and at the  expense of the  Indemnitor;
provided that (A) the amount of any  settlement  such  Indemnitee may enter into
must be consented to by the Indemnitor and no Indemnitee may in connection  with
any such  investigation,  defense  or  settlement,  without  the  consent of the
Indemnitor, require the Indemnitor or any of its subsidiaries to take or refrain
from taking any action  (other than payment of such a  settlement  amount) or to
make any public statement,  which such Person reasonably considers to materially
adversely  affect its interest,  and (B) such Indemnitee may not take control of
any  investigation,  defense or settlement which could entail a risk of criminal
liability  to  the  Indemnitor  or  any  of  its  subsidiaries  or to any of the
Partners. Upon the request of the Indemnitor, each Indemnitee shall use its best
efforts  to keep the  Indemnitor  reasonably  apprised  of the  status  of those
aspects of such investigation and defense controlled by

                                       -55-
<PAGE>


such Indemnitee and shall provide such  information  with respect thereto as the
Indemnitor  may reasonably  request.  The  Indemnitor  shall  cooperate with the
Indemnitee in all reasonable respects with respect thereto.

         (iii) Any Indemnitor may, by notice to the Indemnitees, take control of
all aspects of the  investigation and defense of all claims asserted against it,
and may employ  counsel of its choice and at its expense;  provided  that (A) no
Indemnitor  may without the consent of any  Indemnitee  agree to any  settlement
that  requires  such  Indemnitee  to make any  payment  that is not  indemnified
hereunder,  or does not grant a general release to such  Indemnitee,  and in any
event such Indemnitor may not in connection with any such investigation, defense
or  settlement,  without the  consent of any  Indemnitee,  take or refrain  from
taking any action which would  reasonably be expected to  materially  impair the
indemnification of such Indemnitee hereunder or would require such Indemnitee to
take or refrain  from taking any action or to make any public  statement,  which
such Person reasonably  considers to materially  adversely affect its interests,
(B) no Indemnitor may take control of any investigation,  defense or settlement,
without  the  consent of any  Indemnitee,  if the  liabilities  involved in such
proceedings involve any material risk of the sale, forfeiture or loss of, or the
creation of any Lien on, any property of such Indemnitee  beyond its interest in
the  Partnership,  and (C) no Indemnitor may take control of any  investigation,
defense or  settlement  which could  entail a risk of criminal  liability to any
Indemnitee.  Upon the request of any  Indemnitee,  the Indemnitor  shall use its
best efforts to keep such Indemnitee  reasonably apprised of the status of those
aspects of such  investigation  and defense  controlled by such  Indemnitor  and
shall  provide such  information  with respect  thereto as such  Indemnitee  may
reasonably  request.  The Indemnitees shall cooperate with the Indemnitor in all
reasonable respects with respect thereto.

     (iv) To the extent that any income  allocation with respect to the Priority
Distribution or the  Distribution  Imbalance  Distributions is not held to be in
accordance with the requirements of the Code, KM shall promptly  reimburse Shell
or its Affiliates the amount by which the (a) Net Present Value of the net after
tax cash flow to Shell or its  Affiliates  computed at a 35% income tax rate and
using the  allocation  methods  set out in this  Agreement  determined  with the
effect of any adjustments not directly attributable to the Priority Distribution

the Net Present Value of the net after tax cash flow to Shell or its  Affiliates
computed  at a 35% income tax rate and using the  allocation  methods as revised
and adjusted for allocations pursuant to Section 3.3(p).

     SECTION 5.6  Compensation; Expenses and Loans.

     (a) Compensation and Reimbursement. Except as otherwise provided in Section
1.9(c),  Section  5.6(d) and this  Section  5.6, no Partner or  Affiliate of any
Partner  shall receive any salary,  fee, or draw for services  rendered to or on
behalf of the  Partnership or otherwise in its capacity as a Partner,  nor shall
any Partner or Affiliate of any Partner be reimbursed for any expenses  incurred
by such Partner or Affiliate  on behalf of the  Partnership  or otherwise in its
capacity as a Partner.

     (b)  Expenses.  Except as provided in Section 5.6 (c), the General  Partner
may charge the Partnership,  and shall be reimbursed,  for any reasonable direct
expenses incurred in connection with the Partnership's  business and (i) payable
to  Persons  other than any  General  Partner or any  Affiliate  of any  General
Partner or (ii) payable to the General  Partner or any  Affiliate of any General
Partner to the extent included in the Operating Budget.

     (c) Selection of Service Providers and  Compensation.  The Partnership will
require professional and administrative services ("Services") including, but not
limited to those  listed on Exhibit C. The  Partnership  may employ its staff to
provide  some,  none,  or all of the  Services it  requires  at its  discretion,
subject to the delegation of authorities  of the General  Partner.  In the event
the Partnership requires Services that are provided outside the Partnership, the
General  Partner  will have any such  outside  Services  provided  by  qualified
suppliers at competitive market rates subject to the following:

         (i)  All  service  providers  will be  selected  by the  approval  of a
Majority of the Partners.


                                       -57-
<PAGE>


         (ii) The competitiveness of the service providers will be determined by
benchmarking costs of equivalent  service providers for equivalent  Services (as
defined  in section  5.6  (c)(iii)  ),  competitive  bidding,  or any other cost
effective procedure established by the General Partner.

         (iii)  Equivalent  Services  will be  interpreted  to require  that the
service being offered is provided by equivalently qualified individuals or firms
who have equivalent skills and experience using equivalent tools and/or relevant
equipment in providing  such  services.  Whether a Service is  equivalent or not
shall be determined by  considering  the  contemplated  transaction  as a whole.
Further,  for  some  services,  in  order  for  the  service  to  be  considered
equivalent,  certain of the tools  and/or  relevant  equipment  utilized  by the
outside service  provider will need to be specified by the General Partner (e.g.
in order for an  affiliate  of the  General  Partner to receive  consistent  and
meaningful  accounting  data,  the General  Partner  may  specify  the  computer
software and accounting systems to be utilized by service providers.)

         (iv) An  Affiliate  of any  Partner  may bid or provide a  proposal  to
provide any such outside service.  In the event the Partners  select,  after the
one year  transition  period,  an  Affiliate  of a Partner and such  Affiliate's
proposal to provide a service exceeded another qualified  supplier's proposal to
provide an equivalent  service by fifteen percent (15%),  then the Partner whose
Affiliate  provided such Service shall reimburse the Partnership for any charges
for such Services in amounts exceeding the fifteen percent (15%) tolerance.  The
intent of this  section is to permit the  Partners to select an Affiliate of any
Partner to provide any outside service, however the cost paid by the Partnership
would in effect be at competitive market rates.

         (v) The Partners agree that as a transition  period, for the first year
of the  Partnership,  the General Partner will have the discretion to enter into
agreements  with  service  providers,  regardless  of  affiliation,  as it deems
necessary  to  continue  without  interruption  the  conduct of  business of the
Partnership.

     (d) Loans. Any Person may, with the consent of the General Partner, lend or
advance money to the Partnership. If any Partner shall make any loan or loans to
the Partnership or advance

                                       -58-
<PAGE>


money on its behalf, the amount of any such loan or advance shall not be treated
as a  Capital  Contribution  but shall be a debt due from the  Partnership.  The
amount of any such loan or advance by a lending  Partner  shall be repayable out
of the  Partnership's  cash and shall bear  interest at such rate as the General
Partner  and the  lending  Partner  shall agree but not in excess of the maximum
rate  permitted by law. If any General  Partner,  or an Affiliate of any General
Partner, is the lending Partner, the rate of interest shall be determined by the
General  Partner  taking  into  consideration,  without  limitation,  prevailing
interest rates and the interest rates the lender is required to pay in the event
such lender has itself  borrowed funds to loan or advance to the Partnership and
the terms and conditions of such loan, including the rate of interest,  shall be
no less favorable to the Partnership  than if the lender had been an independent
third party. None of the Partners shall be obligated to make any loan or advance
to the Partnership.

     SECTION 5.7  Temporary Investments.

     All Property in the form of cash not otherwise  invested shall be deposited
for the benefit of the Partnership in one or more accounts of the Partnership or
any of its Affiliates,  maintained in such financial institutions as the General
Partner shall determine or shall be invested in short-term  liquid securities or
other  cash-equivalent  assets or shall be left in escrow, and withdrawals shall
be made only in the regular course of Partnership  business on such signature or
signatures  as the  General  Partner  may  determine  from time to time.  Unless
otherwise  determined  by  Partners  holding a majority  of the  Interests,  the
Partnership's  cash shall be managed by Shell or its  Affiliates  in  accordance
with the Shell cash  management  agreements  in effect from time to time between
Shell and its various Affiliates,  and such agreement shall be deemed to fulfill
the requirements of this Section 5.7.

     SECTION 5.8 Audit Committee.

         (a) The General  Partner  shall  establish  an Audit  Committee  of the
Partnership  that  shall  consist  of three  persons  appointed  by the  General
Partner.  Excluded  from  membership  are officers (or  relatives of  officers),
employees,  and  consultants  (other than members)  compensated  on a continuing
basis by the Partnership.

                                       -59-

         (b) The Audit Committee shall annually review (i) the scope and results
of the independent  accountants'  audits, (ii) the adequacy of the Partnership's
internal accounting controls and internal audit program, (iii) the Partnership's
compliance with accounting and reporting standards, and (iv) the adequacy of the
Partnership's insurance policies, if any, programs and practices,  including the
amount of insurance coverage, if any, for the Partnership's assets,  manager and
officers.

         (c) The Audit  Committee  shall review (i) the financial  statements of
the  Partnership  with the Chief  Financial  Officer and may call upon the Chief
Financial  Officer for such other reports and discussions as the Audit Committee
may consider desirable,  and (ii) each annual report on the financial statements
submitted by the  independent  accountants and may call upon them for such other
reports and discussions as the Audit Committee may consider desirable.

         (d) The Audit Committee shall report its findings,  recommendations and
conclusions to the Partners at least once each year. The Audit  Committee  shall
also perform such other  functions  and exercise such powers as may be delegated
to it from time to time by the General Partner.

         (e) The Audit Committee shall consult with the  Partnership's  officers
and thereafter  recommend to the General Partner the independent  accountants to
be nominated for  appointment  each year, and upon  appointment  the independent
accountants   shall  have  direct  access  to  the  Audit   Committee.   Upon  a
determination  that audited  financial  statements  are  required,  the external
auditor's  used by Shell Oil Company  shall be  appointed  as the  Partnership's
auditors.

         (f)  The  Audit  Committee  shall  periodically  review  and  recommend
polices,  procedures and practices of the Partnership relating to the principles
which the  Partnership  should  follow in the  conduct  of its  operations,  the
business ethics of its officers and employees,  the social  responsibilities  of
the  Partnership,  and  compliance  by the  Partnership  with  applicable  laws,
regulations,  permits,  and other legal obligations,  including  compliance with
applicable environmental or health and safety laws and regulations.

     SECTION 6.1  Rights or Powers.

     The Limited  Partners shall not have any right or power to take part in the
management or control of the  Partnership  or its business and affairs or to act

thereof,  may also be an employee or agent of the  Partnership or a stockholder,
director or officer of a General Partner.  The existence of these  relationships

otherwise affect the limited liability of any Limited Partner.

     SECTION 6.2  Voting Rights.

     Except as otherwise  provided  herein,  the Limited Partners shall have the

to the General  Partner  not later than thirty (30) days after such  approval or
consent was requested by the General  Partner.  The General  Partner may require
response  within a shorter  time,  but not less than ten (10)  Business  Days. A
failure to  respond in any such time  period  shall  constitute  a vote which is
consistent with the General Partner's recommendation with respect

                                       -61-
<PAGE>


to the  proposal.  If the General  Partner  receives the  necessary  approval or
consent of the Limited  Partners to such action,  the General  Partner  shall be

by the Limited Partners.

                                   ARTICLE VII

connection with the conduct of the Partnership and the operation of its business
in accordance with this Agreement.

     (b) Accounting Methods.

shall keep its books and records accordingly.

the one hand and the  Partners  or their  Affiliates  on the other hand shall be
treated as occurring  between the  Partnership and a Person who is not a Partner
within the meaning of Section  707(a)(1) of the Code and such amounts payable by
the Partnership to any Partner or its Affiliates  shall be considered an expense
or  capital  cost,  as the case may be, of the  Partnership  for  income tax and
financial reporting purposes, and shall not be considered a distribution to such
Partner  including,  without  limitation,  in maintaining such Partner's Capital
Account,  and any such amounts  payable by any Partner or its  Affiliates to the
Partnership   shall  not  be  considered  a  contribution  to  the  Partnership,
including, without limitation, in maintaining such Partner's Capital Account.

                                       -62-

     (c)  Access  to  Books,   Records,  etc.  Any  Partner  or  any  agents  or

frequency,  may visit and inspect any of the properties of the  Partnership  and
examine any information  directly related to the operational or financial status

with the General  Partner and its  directors  and officers  and the  independent
accountants of the  Partnership,  all at such  reasonable  times and as often as
such Partner or any agents or  representatives  of such  Partner may  reasonably
request.  The  rights  granted to a Partner  pursuant  to this  Section  7.1 are
expressly   subject  to  the  terms  and  conditions  of  the  Limited   Partner

and guidelines may be established from time to time.

requesting  such  audit.  Audits  may  extend  to  financial   transactions  and
operational  matters,  and  include  all areas  deemed  appropriate  for review,
including an  environmental  or health and safety audit,  in order to support an
opinion as to the effectiveness of internal  controls.  A reporting of the audit
findings  shall be submitted to each  Partner.  The  frequency  and scope of the
audits shall be no more frequently than once per Fiscal Year.

     Except as otherwise  permitted by this Agreement,  no Interest Holder shall

security  for the  payment  of a debt,  except  Indebtedness  (i) for  which the
borrower  gives the General  Partner prior written notice and (ii) made in favor
of a state or federal bank or other publicly held or privately owned entity that
is  ordinarily  engaged in the  business of making  loans.  If Shell  reasonably
believes that  participation  of any such lender in the Indebtedness of KM would
adversely affect the business of Shell,  Shell Oil Company or their  Affiliates,
KM agrees that it will not provide any confidential information received from or
pertaining to the  Partnership  to such lender and that the General  Partner may
restrict the  dissemination  of information to KM during any period during which
such Indebtedness is outstanding;  provided,  however that KM shall not have any
limitation  upon its access to  Partnership  information  at the  offices of the
Partnership  or the General  Partner  and that KM shall not have any  limitation
upon its right to receive  and to use  information  that KM is  required to make
public by reason of federal or state securities laws or other statutes, rules or
regulations.

     SECTION 9.2  Permitted Transfers.

      Subject to the conditions and  restrictions  set forth in Section 9.3, the
General  Partner  or an  Interest  Holder  may at any time  Transfer  all or any
portion of its Interest to (a) any Interest  Holder,  (b) any Affiliate of Shell
or Shell Oil Company or any  Affiliate  of an  Interest  Holder,  including  the
transferor, (c) the transferor's executor,  administrator,  trustee, or personal
representative to whom such Interests are transferred involuntarily by operation
of law, or (d) any Purchaser in accordance  with Article XIII (any such Transfer
being referred to in this Agreement as a "Permitted Transfer"). Before the tenth
anniversary of the formation of the Partnership,  no Transfer shall be permitted
other than as provided in Section 9.2 (a) or (b).

         SECTION 9.3  Conditions to Permitted Transfers.

     A Transfer  shall not be treated as a Permitted  Transfer under Section 9.2
unless and until the following conditions are satisfied:

     (a)  Except  in the  case  of a  Transfer  of  Interests  involuntarily  by
operation of law, the transferor and transferee shall execute and deliver to the
Partnership such documents and

                                       -67-
<PAGE>


instruments  of conveyance as may be necessary or  appropriate in the opinion of
counsel to the  Partnership to effect such Transfer and to confirm the agreement
of the transferee to be bound by the provisions of this  Agreement.  In the case
of a Transfer of Interests involuntarily by operation of law, the Transfer shall
be  confirmed  by  presentation  to the  Partnership  of legal  evidence of such
Transfer, in form and substance  satisfactory to counsel to the Partnership.  In
all  cases,  the  Partnership  shall  be  reimbursed  by the  transferor  and/or
transferee  for all costs and expenses that it  reasonably  incurs in connection
with such Transfer.

     (b) Except in the case of a Transfer involuntarily by operation of law, the
Transfer  will not cause the  Partnership  to terminate  for federal  income tax
purposes and the Transfer  will not cause the  application  of the rules of Code
Sections  168(g)(1)(B)  and 168(h)  (generally  referred  to as the "tax  exempt
entity leasing rules") or similar rules to apply to the Partnership, Partnership
Property,  or the General Partner and Interest  Holders and the transferor shall
furnish to the  Partnership  an opinion of counsel to such effect.  Such counsel
and opinion shall be reasonably  satisfactory  to the General  Partner,  and the
General Partner shall provide to such counsel any information  available to such
General Partner relevant to such opinion.

     (c) The transferor and transferee  shall furnish the  Partnership  with the
transferee's taxpayer identification number, sufficient information to determine
the  transferee's  initial  tax  basis  in the  Interests  transferred  (or  the
transferee's tax basis in the Partnership  Property),  and any other information
reasonably  necessary to permit the Partnership to file all required federal and
state tax returns and other legally required information  statements or returns.
Without limiting the generality of the foregoing,  the Partnership  shall not be
required to make any distribution  otherwise provided for in this Agreement with
respect to any transferred Interests until it has received such information.

     (d)  Except  in the  case  of a  Transfer  of  Interests  involuntarily  by
operation  of law,  either  (a) such  Interests  shall be  registered  under the
Securities Act of 1933, as amended, and any applicable state securities laws, or
(b) such Transfer will be exempt from all applicable  registration  requirements
and will not violate any applicable  laws  regulating the Transfer of securities
and, except in the case of a transfer to another  Partner,  the transferor shall
provide an opinion of counsel,  which  opinion and counsel  shall be  reasonably
satisfactory to the General Partner, to such effect.

                                       -68-
<PAGE>



     (e)  Except  in the  case  of a  Transfer  of  Interests  involuntarily  by
operation of law, such Transfer will not cause the  Partnership  to be deemed to
be an "investment  company" under the Investment Company Act of 1940 as amended,
and the  transferor  shall  provide an opinion of  counsel,  which  opinion  and
counsel shall be reasonably  satisfactory to the General Partner, to such effect
and the General Partner shall provide to such counsel any information  available
to such General Partner relevant to such opinion.

     SECTION 9.4  Prohibited Transfers.

     Any purported  Transfer of Interests that is not a Permitted Transfer shall
be null  and void and of no force or  effect  whatever;  provided  that,  if the
Partnership is required to recognize a Transfer that is not a Permitted Transfer
(or if the Partnership,  in its sole discretion,  elects to recognize a Transfer
that is not a Permitted  Transfer),  the interest  Transferred shall be strictly
limited to the transferor's  rights to allocations and distributions as provided
by this Agreement with respect to the transferred  Interests,  which allocations
and  distributions may be applied (without limiting any other legal or equitable
rights of the Partnership) to satisfy any debts, obligations, or liabilities for
damages that the  transferor  or  transferee  of such  Interests may have to the
Partnership.

Persons may incur (including, without limitation,  incremental tax liability and
lawyers' fees and  expenses) as a result of such Transfer or attempted  Transfer
and  efforts to enforce  the  indemnity  granted  hereby.  Any  Transfer  of any
Interest by KM  prohibited  by the terms of this  Section  9.4 shall  provide to

     SECTION 9.7 Covenants; Representations Regarding Transfers; Legend.

     (a) Each Interest Holder hereby  represents,  covenants and agrees with the
Partnership for the benefit of the Partnership  and all Interest  Holders,  that
(i) he is not  currently  making a market  in LP  Interests  and will not in the
future make a market in LP Interests, (ii) he will not Transfer his LP Interests
on an established  securities  market,  a secondary  market (or the  substantial
equivalent  thereof)  within  the  meaning  of Code  Section  7704(b)  (and  any
regulations,   proposed   regulations,   revenue  rulings,   or  other  official
pronouncements  of the Internal Revenue Service or Treasury  Department that may
be  promulgated  or  published   thereunder),   and  (iii)  in  the  event  such
Regulations,   revenue  rulings,  or  other  pronouncements  treat  any  or  all
arrangements which facilitate the selling of partnership interests and which are
commonly  referred to as  "matching  services"  as being a  secondary  market or
substantial  equivalent  thereof, he will not Transfer any LP Interest through a
matching  service  that is not  approved  in  advance by the  Partnership.  Each
Interest  Holder further agrees that he will not Transfer any LP Interest to any
Person  unless  such  Person  agrees to be bound by this  Section  9.7(a) and to
Transfer such LP Interests only to Persons who agree to be similarly  bound. The
Partnership  shall,  from time to time and at the request of an Interest Holder,
consider  whether to approve a matching  service and shall  notify all  Interest
Holders of any matching service that is so approved.

     (b) Each Interest  Holder  hereby  agrees that the following  legend may be
placed upon any counterpart of this  Agreement,  the  Certificate,  or any other
document or instrument evidencing ownership of LP Interests:


                                       -71-
<PAGE>


         The Interests  represented  by this  document have not been  registered
     under any  securities  laws and the  transferability  of such  Interests is
     restricted.  Such Interests may not be sold,  assigned or transferred,  nor
     will any assignee,  vendee, transferee or endorsee thereof be recognized as
     having  acquired any such Interests by the issuer for any purposes,  unless
     (1) a registration  statement under the Securities Act of 1933, as amended,
     with respect to such  Interests  shall then be in effect and such  transfer
     has been qualified under all applicable  state  securities laws, or (2) the
     availability of an exemption from such registration and qualification shall
     be established to the satisfaction of counsel to the Partnership.

         The  Interests  represented  by this  document  are  subject to further
     restriction as to their sale, transfer, hypothecation, or assignment as set
     forth in the Agreement of Limited Partnership and agreed to by each Limited
     Partner.  Said restriction  provides,  among other things, that no Interest
     may be  transferred  without  first  offering  such  Interest  to the other
     Interest  Holders and  General  Partners,  and that no vendee,  transferee,
     assignee,  or endorsee of an Interest Holder shall have the right to become
     a  substituted  Limited  Partner  without the consent of all of the General
     Partners  which  consent may be given or withheld in the sole and  absolute
     discretion of the General Partner.

     SECTION  9.8  Distributions  and  Applications  in Respect  to  Transferred
Interests.

     If any Interest is sold, assigned, or Transferred during any Fiscal Year in
compliance  with the provisions of this Article IX, Profits,  Losses,  each item
thereof,  and all other items attributable to the Transferred  Interest for such
Fiscal  Year shall be divided  and  allocated  between  the  transferor  and the
transferee  by taking into account their  varying  Interests  during such Fiscal
Year in accordance with Code Section 706(d), using any conventions  permitted by
law and selected by the General Partner. All distributions on or before the date
of  such  Transfer  shall  be  made to the  transferor,  and  all  distributions
thereafter  shall be made to the transferee.  Solely for purposes of making such
allocations and distributions, the Partnership shall recognize such Transfer not
later than the end of the calendar month during which it is given notice of such
Transfer,  provided  that, if the  Partnership  is given notice of a Transfer at
least ten (10) Business Days prior to the Transfer the

                                       -72-
<PAGE>


Partnership  shall recognize such Transfer as of the date of such Transfer,  and
provided  further that, if the Partnership does not receive a notice stating the
date such Interest was  Transferred  and such other  information  as the General
Partner  may  reasonably  require  within  thirty (30) days after the end of the
Fiscal  Year  during  which the  transfer  occurs,  then all such items shall be
allocated,  and all distributions shall be made, to the Person who, according to
the books and records of the  Partnership,  was the owner of the Interest on the
last day of the Fiscal  Year  during  which the  Transfer  occurs.  Neither  the
Partnership  nor any  General  Partner  shall  incur any  liability  for  making
allocations and  distributions in accordance with the provisions of this Section
9.8,  whether or not any General Partner or the Partnership has knowledge of any
Transfer of ownership of any Interest.

admitted to the Partnership as a General  Partner without the unanimous  consent
of the Partners.

     SECTION 10.2  Covenant Not to Withdraw,  Transfer,  or Dissolve.

covenants  and  agrees  not to (a)  take any  action  to file a  certificate  of
dissolution or its equivalent with respect to itself, (b) withdraw or attempt to
withdraw from the  Partnership,  except in connection with a Transfer  permitted
under  Section  10.3(a)  or in  connection  with  a sale  of all of the  General
Partner's  Partnership  interest in accordance with the  requirements of Article
XIII,  (c)  exercise any power under the Act to dissolve  the  Partnership,  (d)
transfer  all or any  portion of his  interest in the  Partnership  as a General
Partner,  except as provided herein or (e) petition for judicial  dissolution of
the  Partnership.  Further,  the General Partner hereby  covenants and agrees to
continue  to carry  out the  duties  of a General  Partner  hereunder  until the
Partnership is dissolved and liquidated pursuant to Article XII.

     SECTION 10.3  Permitted Transfers.

     (a) A General  Partner may  Transfer  all or any portion of its GP Interest
(i) at any time to any other General Partner, (ii) at any time to any Person who
is such General Partner's Affiliate on both the day such General Partner becomes
a General Partner and the day of such Transfer;  provided however that any Shell
Affiliate  holding GP Interests is  authorized to transfer all or any portion of
such GP Interests to any Shell  Affiliate or any Affiliate of Shell Oil Company,
(iii) at any time  involuntarily  by operation of law, or (iv) to any Person who
is approved by all of the other  Partners;  provided that no such Transfer shall
be permitted unless and until (a) all of the conditions set forth in Section 9.2
and 9.3 are satisfied,  and (b) such Transfer will not cause the  Partnership to
become  taxable  as a  corporation  for  federal  income  tax  purposes  and the
transferor and transferee  provide the  Partnership  with an opinion of counsel,
which opinion and counsel shall be acceptable to the other General Partners,  to
such effect.

     (b) A transferee of a GP Interest from a General Partner hereunder shall be
admitted as a General Partner with respect to such interest if, but only if, (i)
at the time of such Transfer,  such  transferee is otherwise a General  Partner,
(ii) the transferee is an Affiliate of the transferring  General Partner and all
of the other Partners consent to such admission,  or (iii) the admission of such
transferee as a General Partner is approved by all of the other Partners.

     (c) A  transferee  who  acquires  a GP  Interest  from  a  General  Partner
hereunder by means of a Transfer that is permitted  under this Section 10.3, but
who is not admitted as a General Partner,  shall have no authority to act for or
bind the  Partnership,  to inspect the  Partnership's  books, or otherwise to be
treated as a General Partner or Limited  Partner,  but such transferee  shall be
treated as an  Interest  Holder  who  acquired  an LP  Interest  in a  Permitted
Transfer under Section 9.

     SECTION 10.4  Prohibited Transfers.

     Any purported  Transfer of an interest in the Partnership held by a General
Partner  that is not  permitted by Section 10.3 above shall be null and void and
of no force or effect whatever; provided

                                       -74-
<PAGE>


that,  if the  Partnership  is required to  recognize a Transfer  that is not so
permitted (or if the Partnership, in its sole discretion,  elects to recognize a
Transfer that is not so permitted),  the interest  transferred shall be strictly
limited to the transferor's  rights to allocations and distributions as provided
by this Agreement with respect to the transferred  interest,  which  allocations
and  distributions may be applied (without limiting any other legal or equitable
rights of the Partnership) to satisfy any debts, obligations, or liabilities for
damages  that the  transferor  or  transferee  of such  interest may have to the
Partnership.

     In the case of a Transfer or attempted  Transfer of a Partnership  interest
that is not permitted by Section 10.3 above,  the parties engaging or attempting
to engage in such  Transfer  shall be liable to indemnify  and hold harmless the
Partnership and the other Partners from all cost,  liability and damage that any
of  such  indemnified   Persons  may  incur  (including,   without   limitation,
incremental  tax  liability  and lawyers' fees and expenses) as a result of such
Transfer or  attempted  Transfer  and efforts to enforce the  indemnity  granted
hereby.

     SECTION 10.5 Termination of Status as General Partner.

     (a) The General  Partner shall cease to be a General Partner upon the first
to occur of (i) the  Bankruptcy of such General  Partner,  (ii) the  involuntary
Transfer  by  operation  of  law  of  such  General  Partner's  interest  in the
Partnership,  (iii) the vote of a Majority of the Limited  Partners to approve a
request by such General Partner to retire, or (iv) the vote of a majority of the
Limited  Partners to remove such General  Partner after such General Partner has
attempted to make a Transfer of his  Partnership  interest that is not permitted
by  Section  10.3,  committed  a  material  breach  of  this  Agreement  or  his
representations and warranties hereunder, or committed any other act or suffered
any  other  conditions  that  would  justify  a  decree  of  dissolution  of the
Partnership  under the laws of the State of Texas.  In the event a Person ceases
to be a General  Partner  without having  Transferred  his entire  interest as a
General Partner, such Person shall be treated as a Limited Partner that received
its LP Interest as a result of a Transfer that is a Permitted  Transfer pursuant
to Sections 9.2 and 10.3.


                                       -75-

     If the General  Partner ceases to be a General Partner for any reason under
this Agreement, such Person shall continue to be liable as a General Partner for
all debts and  obligations of the  Partnership  existing at the time such Person
ceases to be a General Partner,  regardless of whether, at such time, such debts
or liabilities were known or unknown,  actual or contingent  provided,  however,
that the assets of any General Partner shall be subject to the protection of the
Act. A Person shall not be liable as a General Partner for Partnership debts and
obligations arising after such Person ceases to be a General Partner. Any debts,
obligations,  or  liabilities  in damages to the  Partnership  of any Person who
ceases to be a General  Partner shall be  collectible by any legal means and the
Partnership  is  authorized,  in  addition  to any other  remedies  at law or in
equity,  to  apply  any  amounts  otherwise  distributable  or  payable  by  the
Partnership to such Person to satisfy such debts, obligations, or liabilities.

     (b) If at the time a Person  ceases to be a General  Partner such Person is
also a Limited Partner or an Interest Holder with respect to LP Interests,  such
cessation shall not affect such Person's rights and obligations  with respect to
such LP Interests.

     SECTION 10.6  Election of New General Partners.

     Provided the Partnership has one or more General Partners,  any Partner may
nominate one or more Persons for election as additional  General  Partners.  The
election of an additional General Partner shall require an affirmative vote of a
majority of the Partners.

                                POWER OF ATTORNEY

     SECTION 11.1  General Partner as Attorney-In-Fact.

     Each Partner hereby makes,  constitutes,  and appoints the General Partner,
each successor General Partner, and the Liquidator,  severally,  with full power
of substitution and resubstitution,  its true and lawful attorney-in-fact for it
and in its name, place, and stead and for its use and benefit, to sign, execute,
certify, acknowledge, swear to, file, publish and record (a) all certificates of
limited   partnership,   amended  name  or  similar   certificates,   and  other
certificates  and instruments  (including  counterparts of this Agreement) which
the  General  Partner  or  Liquidator  may  deem  necessary  to be  filed by the
Partnership  under  the  laws of the  State  of  Texas  or any  other  state  or
jurisdiction  in which the  Partnership is doing or intends to do business;  (b)
any and all  amendments,  restatements  or  changes  to this  Agreement  and the
instruments  described  in (a), as now or hereafter  amended,  which the General
Partner may deem necessary to effect a change or modification of the Partnership
approved  by the  Partners  in  accordance  with the  terms  of this  Agreement,
including, without limitation, amendments or changes to reflect (i) the exercise
by any General Partner of any power granted to it under this Agreement; (ii) any
amendments  adopted  by the  Partners  in  accordance  with  the  terms  of this
Agreement;  (iii)  the  admission  of any  substituted  Partner;  and  (iv)  the
disposition  by any  Partner  of its  Interest;  and  (c)  all  certificates  of
cancellation and other  instruments  which the General Partner or Liquidator may
deem necessary to effect the  dissolution  and  termination  of the  Partnership
pursuant to the terms of this Agreement;  and (d) any other  instrument which is
now or may hereafter be required by law to be filed on behalf of the Partnership
or is deemed  necessary by the General  Partner or Liquidator to carry out fully
the  provisions  of this  Agreement in accordance  with its terms.  Each Partner
authorizes  each such  attorney-in-fact  to take any further  action  which such
attorney-in-fact  shall  consider  necessary  in  connection  with  any  of  the
foregoing,  hereby giving each such attorney-in-fact full power and authority to
do and perform  each and every act or thing  whatsoever  requisite to be done in
connection  with  the  foregoing  as  fully  as such  Partner  might or could do
personally,   and   hereby   ratifying   and   confirming   all  that  any  such
attorney-in-fact shall lawfully do or cause to be done by virtue thereof.

     SECTION 11.2  Nature as Special Power.

     The power of attorney granted pursuant to this Article XI:

     (a) Is a special  power of  attorney  coupled  with an
interest and is irrevocable;

     (b) May be  exercised by any such  attorney-in-fact  by listing the Limited
Partners  executing any agreement,  certificate,  instrument,  or other document
with  the   single   signature   of  any   such   attorney-in-fact   acting   as
attorney-in-fact for such Limited Partners; and

     (c) Shall survive the subsequent Bankruptcy,  insolvency,  dissolution,  or
cessation of existence of a Limited Partner and shall survive the delivery of an
assignment  by a Limited  Partner of the whole or a portion of its LP Interests,
except  that  where  the  assignment  is of such  Limited  Partner's  entire  LP
Interests and the assignee, with the consent of the General Partner, is admitted
as a  substituted  Limited  Partner,  the power of  attorney  shall  survive the
delivery  of  such  assignment  for  the  sole  purpose  of  enabling  any  such
attorney-in-fact to effect such substitution.

                                   ARTICLE XII
                           DISSOLUTION AND WINDING UP

     SECTION 12.1  Liquidating Events.

     The Partnership shall dissolve and commence winding up and liquidating upon
the first to occur of any of the following ("Liquidating Events"):

     (a) The thirtieth (30th) anniversary of the formation of the Partnership;

     (b) The sale of all or substantially all of the Partnership Property;

     (c) The unanimous vote by Partners to dissolve,  wind up, and liquidate the
Partnership;


                                       -78-
<PAGE>


     (d) The happening of any other event that makes it unlawful, impossible, or
impractical to carry on the business of the Partnership; or

     (e) The  withdrawal or removal of a General  Partner,  the  assignment by a
General  Partner of its entire  interest in the  Partnership  or any other event
that causes a General  Partner to cease to be a general  partner  under the Act,
provided  that any such event shall not  constitute a  Liquidating  Event if the
Partnership is continued pursuant to this Section 12.1.

     The Partners hereby agree that, notwithstanding any provision of the Act or
the Texas Revised  Partnership Act, the Partnership  shall not dissolve prior to
the  occurrence  of a  Liquidating  Event.  During  the  first  ten years of the
Partnership, the General Partner and its Affiliates agree not to cause any event
under Section  12.1(e) to occur or, if such an event is not avoidable,  agree to
vote to continue or to reconstitute  the Partnership as provided in this Section
12.1.  Upon the occurrence of any event set forth in Section 12.1(e) (so long as
no other Liquidating Event has occurred), the Partnership shall not be dissolved
or  required  to be wound up if (x) at the time of such event  there is at least
one remaining  General  Partner and that General Partner carries on the business
of the Partnership (any such remaining  General Partner being hereby  authorized
to carry on the  business of the  Partnership),  or (y) within  ninety (90) days
after such  event all  remaining  Partners  agree in  writing  to  continue  the
business of the Partnership and to the appointment,  effective as of the date of
such event, of one or more additional General Partners. If it is determined,  by
a court of competent  jurisdiction,  that the Partnership has dissolved prior to
the  occurrence of a Liquidating  Event,  or if upon the  occurrence of an event
specified in Section 12.1(e),  the Partners fail to appoint a substitute General
Partner  effective as of such event and to agree to continue the business of the
Partnership as provided in this Section 12.1,  then within an additional  ninety
(90) days  after  such  determination  or the last day of such  ninety  (90) day
period, as the case may be (the "Reconstitution  Period"), a two-thirds majority
of the  Partners  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  elected by such  two-thirds
majority.  Upon any such election by a two-thirds majority of the Partners,  all
Partners shall be bound thereby and shall be deemed to have  consented  thereto.
Unless


                                       -79-
<PAGE>


such an election is made within the Reconstitution Period, the Partnership shall
wind up its affairs in accordance with Section 12.2. If such an election is made
within the Reconstitution Period, then:

         (i) The  reconstituted  limited  partnership  shall  continue until the
occurrence of a Liquidating Event as provided in this Section 12.1;

         (ii) If the successor  general partner is not a former General Partner,
then the interest in the  Partnership  of any former  General  Partner  shall be
treated thenceforth as the interest of a Limited Partner; and

         (iii) All necessary  steps shall be taken to cancel this  Agreement and
the Certificate and to enter into 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 Article
XI and shall cause such certificate of limited partnership for the reconstituted
partnership  to be filed in the  office  of the  Secretary  of State of Texas in
accordance with the Act; provided that the right of a two-thirds majority of the
Partners to select a successor  general partner and to reconstitute and continue
the business of the Partnership  shall not exist and may not be exercised unless
the  Partnership  has  received an opinion of counsel  that the  exercise of the
right would not result in the loss of limited  liability of any Limited  Partner
and neither the Partnership nor the reconstituted  partnership would cease to be
treated as a  partnership  for federal  income tax purposes upon the exercise of
such right to continue.

     SECTION 12.2  Winding Up.

     Upon the occurrence of a Liquidating  Event, the Partnership shall continue
solely  for the  purposes  of  winding  up its  affairs  in an  orderly  manner,
liquidating its assets,  and satisfying the claims of its creditors and Partners
and no Partner shall take any action that is inconsistent with, or not necessary
to or appropriate for, the winding up of the Partnership's business and affairs.
To the extent not inconsistent  with the foregoing,  all covenants  contained in
this Agreement and obligations  provided for in this Agreement shall continue to
be fully binding on the Partners until such time as the Partnership Property has
been  distributed  pursuant to this  Section 12.2 and the  Certificate  has been
canceled in accordance  with the Act. The Liquidator  shall be  responsible  for
overseeing the winding up and  dissolution of the  Partnership,  shall take full
account  of  the  Partnership's   liabilities  and  Property,  shall  cause  the
Partnership  Property  to  be  liquidated  as  promptly  as is  consistent  with
obtaining  the fair value  thereof  unless the Partners  unanimously  consent to
distributions  of all or any part of the  Property in kind,  and shall cause the
Property or the proceeds  therefrom,  to the extent sufficient  therefor,  to be
applied and distributed in the following order:

     (a) First,  to creditors  other than the General Partner in satisfaction of
all of the Partnership's  debts and liabilities other than liabilities for which
reasonable provision for payment has been made and liabilities for distributions
under Section 8.05 of the Act;

     (b) Second, to the payment and discharge of all of the Partnership's  debts
and  liabilities  to the  General  Partner  to  the  extent  adequate  provision
therefore has not been made; and

     (c) Third, to the Partners as provided in Section 4.2,  provided,  however,
that no distribution shall be made pursuant to this Section 12.2(c) that creates
or increases a Capital  Account  deficit for any Interest  Holder which  exceeds
such Interest Holder's  obligation  (deemed and actual) to restore such deficit,
determined  as  follows:  Distributions  shall first be  determined  tentatively
pursuant to this Section 12.2(c) without regard to the Interest Holders' Capital
Accounts,  and then the  allocation  provisions  of  Section 3 shall be  applied
tentatively  as if such tentative  distributions  had been made. If any Interest
Holder shall thereby have a deficit Capital Account

                                       -81-

<PAGE>


which exceeds his  obligation  (deemed and actual) to restore such deficit,  the
actual  distribution  to such Interest  Holder  pursuant to this Section 12.2(c)
shall be equal to the tentative  distribution  to such Interest  Holder less the
amount of the excess to such Interest Holder; and

     (d) The balance,  if any, to the General  Partner and  Interest  Holders in
accordance  with their  positive  Capital  Accounts,  after giving effect to all
contributions, distributions, and allocations for all periods.

No General  Partner shall receive any additional  compensation  for any Services
performed  pursuant  to this  Section 12. The General  Partner  understands  and
agrees that by accepting  the  provisions of this Section 12.2 setting forth the
priority of the  distribution  of the assets of the  Partnership to be made upon
its liquidation,  such General Partner expressly waives any right which it, as a
creditor  of the  Partnership,  might  otherwise  have  under the Act to receive
distributions  of assets pari passu with the other  creditors of the Partnership
in connection  with a distribution  of assets of the Partnership in satisfaction
of any liability of the Partnership,  and hereby  subordinates to said creditors
any such right.

     SECTION 12.3 Compliance With Certain  Requirements of Regulations;  Deficit
Capital Accounts.

     In the  event  the  Partnership  is  "liquidated"  within  the  meaning  of
Regulations  Section  1.704-1(b)(2)(ii)(g),  (x)  distributions  shall  be  made
pursuant to this  Article XII to the General  Partner and  Interest  Holders who
have  positive  Capital   Accounts  in  compliance  with   Regulations   Section
1.704-1(b)(2)(ii)(b)(2),  and (y) if any General Partner's Capital Account has a
deficit balance (after giving effect to all  contributions,  distributions,  and
allocations for all taxable years,  including the taxable year during which such
liquidation occurs), such General Partner shall contribute to the capital of the
Partnership  the amount  necessary to restore  such  deficit  balance to zero in
compliance with  Regulations  Section  1.704-1(b)(2)(ii)(b)(3).  If any Interest
Holder has a deficit  balance in his Capital Account (after giving effect to all
contributions,  distributions  and allocations for all taxable years,  including
the taxable year during which such  liquidation  occurs),  such Interest  Holder
shall have no obligation to make any contribution to the capital of the

                                       -82-

<PAGE>


Partnership  with  respect  to such  deficit,  and  such  deficit  shall  not be
considered a debt owed to the Partnership or to any other Person for any purpose
whatsoever.  In the  discretion  of the  Liquidator,  a pro rata  portion of the
distributions  that would  otherwise be made to the General Partner and Interest
Holders pursuant to this Article XII may be:

     (a)  Distributed  to a trust  established  for the  benefit of the  General
Partner and Interest Holders solely for the purposes of liquidating  Partnership
Property,  collecting amounts owed to the Partnership, and paying any contingent
or unforeseen  liabilities or  obligations of the  Partnership or of the General
Partner arising out of or in connection with the Partnership.  The assets of any
such trust shall be distributed to the General Partner and Interest Holders from
time to  time,  in the  reasonable  discretion  of the  Liquidator  in the  same
proportions  as the amount  distributed to such trust by the  Partnership  would
otherwise  have been  distributed  to the General  Partner and Interest  Holders
pursuant to Section 12.2; or

     (b) Withheld to provide a reasonable  reserve for  Partnership  liabilities
(contingent  or otherwise)  and to allow for the  collection  of the  unrealized
portion of any installment  obligations owed to the  Partnership,  provided that
such withheld  amounts shall be distributed to the General  Partner and Interest
Holders as soon as practicable.

     The portion of the  distributions  that would  otherwise  have been made to
each of the Partners that is instead  distributed to a trust pursuant to Section
12.3(a) or withheld to provide a reserve  pursuant to Section  12.3(b)  shall be
determined  in the same  manner as the  expense  or  deduction  would  have been
allocated  if the  Partnership  had  realized an expense  equal to such  amounts
immediately prior to distributions being made pursuant to Section 12.2.

     SECTION 12.4 Deemed Contribution and Distribution in Liquidation.

     In the event the  Partnership  is liquidated  within the meaning of Section
1.704-1(b)(2)(ii)(g)  of the Regulations but no Liquidating  Event has occurred,
the Property shall not be liquidated, the Partnership's liabilities shall not be
paid or  discharged,  and the  Partnership's  affairs  shall  not be  wound  up.
Instead, solely for federal income tax purposes, the Partnership shall be deemed
to  have  contributed  the  Partnership  Property  subject  to  all  Partnership
liabilities  to a  new  partnership  in  exchange  for  interests  in  such  new
partnership with such interests being  distributed to the Partners in the deemed
liquidation  of  the  Partnership.   In  accordance  with  Regulations   Section
1.704-1(b)(5),  Example 13(v), such deemed  contribution and deemed  liquidation
shall be disregarded in the maintenance and computation of the Partners' capital
accounts.

     SECTION 12.5 Rights of General Partner and Interest Holders.

     The General  Partner and Interest Holder shall look solely to the assets of
the  Partnership  for the return of his Capital  Contribution  and shall have no
right  or  power  to  demand  or  receive  property  other  than  cash  from the
Partnership,  and no Interest Holder shall have priority over any other Interest
Holder  as to  the  return  of  his  Capital  Contributions,  distributions,  or
allocations.  Notwithstanding any provision herein to the contrary,  the General
Partner  shall  have the  right  but not the  obligation  to  purchase  from the
Partnership  all,  but not less than all of the  assets  and  operations  of the
Partnership,  upon the  dissolution  of the  Partnership.  The price paid by the
General  Partners  shall equal one hundred  percent  (100%) of the Fair Value of
such assets and operations on the date of such acquisition.

     SECTION 12.6  Notice of Dissolution.

     In the event a Liquidating  Event occurs or an event occurs that shall, but
for provisions of Section 12.1, result in a dissolution of the Partnership,  the
General  Partner  shall,  within thirty (30) days  thereafter,  provide  written
notice  thereof to each of the Partners  and to all other  parties with whom the
Partnership  regularly conducts business (as determined in the discretion of the
General  Partner)  and shall  publish  notice  thereof in a newspaper of general
circulation in each place in


                                       -84-
<PAGE>


which  the  Partnership  regularly  conducts  business  (as  determined  in  the
discretion of the General Partner).

     SECTION 12.7  Character of Liquidating Distributions.

     All payments  made in  liquidation  of the  interest of a retiring  General
Partner or Interest Holder pursuant to Article XII shall be made in exchange for
the interest of such General Partner or Interest Holder in Partnership  Property
pursuant  to Section  736(b)(1)  of the Code,  including  the  interest  of such
General Partner or Interest Holder in Partnership goodwill.

     SECTION 12.8  The Liquidator.

     (a) Definition.  The "Liquidator" shall mean the General Partner;  provided
that  either (i) if a  Bankruptcy  has  occurred  with  respect  to the  General
Partner,  or (ii) if there is no remaining General Partner,  then a "Liquidator"
shall be  appointed  by the Limited  Partners,  which  Person may be the General
Partner.

     (b) Fees. In the event that the Liquidator is other than a General Partner,
the  Partnership is authorized to pay a reasonable fee to the Liquidator for its
Services  performed pursuant to this Article XII and to reimburse the Liquidator
for its reasonable costs and expenses incurred in performing those services.

     (c)  Indemnification.  Subject  to  Section  5.5(h),  in the event that the
Liquidator is a Person other than a General Partner, the Partnership,  or in the
event that the Partnership has terminated, the General Partner, shall indemnify,
save harmless,  and pay all judgments and claims against, such Liquidator or any
officers,  directors,  agents or  employees  of the  Liquidator  relating to any
liability  or damage  incurred by reason of any act  performed  or omitted to be
performed  by  the  Liquidator,   officer,  director,  agents  or  employees  in
connection  with  the  liquidation  of  the  Partnership,  including  reasonable
attorneys' fees incurred by the Liquidator, officer, director, agent or employee
in connection  with the defense of any action based on any such act or omission,
which  attorneys'  fees  may be paid as  incurred,  except  to the  extent  such
liability or damage is caused by

                                       -85-
<PAGE>


the gross  negligence,  fraud,  or willful  misconduct of the  Liquidator or any
partners, officers, directors, agents or employees of the Liquidator.

                                  ARTICLE XIII
                  PROCEDURES FOR SALES OF PARTNERSHIP INTERESTS

     Section 13.1  General.

     Without the unanimous  consent of the  Partners,  no Partner shall have the
right, except as provided in Section 9.2 and 9.3, to resign as a Partner or sell
or otherwise dispose of its interest in the Partnership  before the tenth (10th)
anniversary  of the  formation of the  Partnership;  provided  that Shell or any
Shell  Affiliate  may make a  Permitted  Transfer to any Shell  Affiliate  or an
Affiliate  of Shell Oil Company.  Notwithstanding  any  provision  herein to the
contrary,  the General  Partner  shall have the right but not the  obligation to
purchase from KM its Interest in the  Partnership,  upon the Bankruptcy of KM or
upon the  completion  of private or  judicial  foreclosure  procedures  or other
collection  procedures  with respect to any debt of KM secured by KM's Interest.
The price to be paid by the General  Partners  shall  equal one hundred  percent
(100%) of the Fair Value of such Interest.

     Section 13.2  Selling Partner.

     After  the  tenth  (10th)  anniversary  of the  Partnership,  a sale  of GP
Interests or LP Interests  shall be effected in  accordance  with the  following
provisions:

     If Shell CO2 LLC or Shell CO2  General  LLC desires to sell all or any part
of its  Interest,  either or both  Shell  Sellers  shall be  referred  to as the
"Selling Partner" and KM shall be referred to as the "Non-Selling  Partner".  If
KM desires to sell all or any part of its  Interest,  KM shall be referred to as
the  "Selling  Partner" and both Shell CO2 LLC or Shell CO2 General LLC shall be
referred to as the "Non-Selling Partner".


                                       -86-

<PAGE>


     (a)  Mutually  Acceptable  Sale.  With the express  written  consent of the
Non-Selling  Partner,  which  consent may be  withheld,  the Selling  Partner is
authorized to sell its Interest to a buyer that in the reasonable opinion of the
General Partner is capable of fulfilling the Selling Partner's obligations under
the Agreement.

     (b) First Look.  The Selling  Partner is authorized to solicit an offer for
its Interest from the Non-Selling  Partner.  The Non-Selling  Partner shall have
the option to make an offer to the Selling Partner within sixty (60) days of the
date of receipt of the notice of  proposed  sale.  If the  Selling  Partner  and
Non-Selling  Partner are unable to agree on a purchase  price within ninety (90)
days of the date of the delivery of the original  notice of proposed  sale,  the
Selling Partner shall retain the option to seek an offer from a third party. The
Selling  Partner is authorized  to sell to a third party if the Selling  Partner
has  provided  the  Non-Selling   Partner  with  a  Last  Look  as  provided  in
subparagraph (c) and the Non-Selling Partner has not exercised such right within
thirty (30) days of the delivery of the notice of Last Look.

     (c) Last Look. If upon  satisfaction  of the  requirements  of subparagraph
(b), the Selling  Partner  desires to sell its  Interest to a third  party,  the
Non-Selling  Partner  shall have the right to  purchase  the  Selling  Partner's
Interest at a price equal to (i) 100% of a firm third party offer,  provided the
third  party offer does not exceed the price  first  offered by the  Non-Selling
Partner pursuant to (b), or (ii) 105% of a firm third party offer,  provided the
third party offer  exceeds the price first  offered by the  Non-Selling  Partner
pursuant  to Section  (b).  Such  option must be  exercised  by the  Non-Selling
Partner within thirty (30) days after the delivery of the notice of Last Look by
the Selling  Partner,  which notice shall be accompanied by a description of all
material terms of the proposed third party sale,  including the price,  identity
of the  proposed  purchaser  and  any  conditions  to  the  completion  of  such
transaction.  Non-cash consideration in the third party offer shall be valued at
Fair Value and may be paid in cash. If the Non-Selling Partner does not exercise
its  option to  purchase  within the thirty  (30) day period  allowed,  then the
Selling  Partner may proceed to complete such sale to the third party and at the
price  and on the  terms  contained  in the Last  Look  notice  provided  to the
Non-Selling  Partner.  If such sale is not completed  within one hundred  twenty
(120)  days  after the  expiration  of the Last Look  option,  then the  Selling
Partner must repeat the Last Look procedure  before making any sale to the third
party.

                                       -87-
<PAGE>



     (d) Tag Along or Drag  Along.  If Shell or its  Affiliates  elect to sell a
share of its Interest  and due to such sale,  Shell or its  Affiliates  shall no
longer be the controlling Partner of the Partnership, KM shall have the right to
participate in such transaction with Shell and its Affiliates. KM shall have the
right to sell the same proportion of its Interest as the proportion of aggregate
Interests to be sold by Shell and its Affiliates.  KM shall receive its pro rata
share of all classes and type of consideration (based on the percentage interest
in the  Partnership  being sold by each  Partner) as to be received by Shell and
its Affiliates.  Shell shall provide  adequate notice to KM of any proposed sale
to which KM's right  hereunder  would apply so that KM will have at least thirty
(30) days prior to the closing of such transaction to determine  whether KM will
participate. Shell will cause the purchaser in any such transaction to afford KM
the full rights and benefits to which it is entitled hereunder, and if KM elects
to  participate  in such sale,  the sale of KM's  Interests  will be consummated
contemporaneously  with  the sale by Shell  and its  Affiliates.  If KM does not
elect to participate in such transaction, Shell shall have the right to elect to
have KM  participate  in such  transaction  with  Shell  on the  same  basis  as
described above.

     Section 13.3 Put and Call Rights.

     Notwithstanding  the  provisions of Section 13.2, the Partners have put and
call rights as set forth in this Section 13.3.

     (a) KM Put Option.  During the times  specified  below,  upon giving ninety
(90) days' written notice to Shell, KM shall have the right to elect to transfer
all of its  Interest to Shell by  redemption  or  acquisition  in exchange for a
purchase  price  equal to the  Fair  Value of KM's  Interest  multiplied  by the
valuation  factors  described  below.  Once KM  provides  notice of  election to
transfer its Interest to Shell,  KM is obligated to complete the transfer at the
purchase price.  The purchase price shall be paid in cash. If notice is received
by Shell during the  Partnership's  (i) fifth year,  such  purchase  price would
equal 65% of the Fair Value of KM's  Interest;  (ii) sixth year,  such  purchase
price would equal 75% of the Fair Value of KM's  Interest;  (iii)  seventh year,
such  purchase  price would equal 85% of the Fair Value of KM's  Interest;  (iv)
eighth year or any time thereafter, such purchase price would be equal to 95% of
the Fair Value of KM's Interest.

                                       -88-

<PAGE>



     (b) Shell Call Option. At any time after the fourth anniversary of the date
of formation of the Partnership ("Anniversary"), Shell has the right to purchase
the  Interest of KM or the  Interest of any  successor  to all or any portion of
KM's  Interest,  in accordance  with the terms of this Section.  The exercise of
Shell's  right  shall be based on a good faith  determination  by Shell that the
purchase of the KM  Interest is  consistent  with the  business  plans of Shell,
including changes in the organization  structure or major business strategies of
Shell  Oil  Company  or  its  Affiliates,  changes  in  the  CO2  business,  new
transactions  proposed with strategic partners of Shell or Shell Oil Company, or
other changes in circumstances  that in the sole discretion of Shell Oil Company
make purchase of the KM Interest desirable.

     (i) Purchase Notice.  To exercise its purchase right,  Shell is required to
deliver to KM a written notice of intent to purchase  ("Purchase  Notice").  The
date the Purchase  Notice is delivered  shall be the effective date for purposes
of  computing  the  Purchase  Price  and the net  present  value of any  Payment
obligation.  The closing of the purchase  shall occur on the first  business day
after 180 days after the effective  date.  Once Shell has delivered the Purchase
Notice,  Shell shall be  obligated  to purchase  the KM  Interest.  The Purchase
Notice shall include the following information:

     (A) the effective date;
     (B) the estimated closing date;
     (C) the business  condition giving rise to Shell's decision to purchase the
         KM Interest; and
     (D) the  name of the  independent  engineering,  accounting  or  investment
         banking firms proposed by Shell to review the Shell data and to compute
         the  Appraised  Value of the KM  Interest  ("Shell  Proposed  Valuation
         Consultant").

     (ii) Selection of Valuation Consultants. Unless KM delivers to Shell within
twenty (20) days of the  effective  date a written  notification  that the Shell
Proposed  Valuation  Consultant  is  unacceptable  to  KM,  the  Shell  Proposed
Valuation  Consultant shall be deemed the finally selected valuation  consultant
with respect to all matters of valuation of the KM Interest ("Valuation

                                       -89-
<PAGE>


Consultant").  If KM and Shell are unable  within such twenty (20) day period to
agree on a Valuation  Consultant,  the Shell Proposed Valuation Consultant and a
proposed  independent  valuation  consultant selected by KM shall select a third
valuation consultant. The Appraised Value shall equal the average of each of the
three Appraised Values determined by the three Valuation  Consultants.  The cost
of the Valuation  Consultants  shall be paid by the  Partnership.  The Valuation
Consultants  shall be given  full  confidential  access to the  books,  records,
properties and employees of the Partnership.

     (iii)  Purchase  Price.  The Fair Value of the KM Interest  shall equal the
Fair Value agreed by KM and Shell or if KM and Shell are unable to agree as to a
Fair Value,  the Fair Value shall equal the Appraised  Value of the KM Interest.
The  Purchase  Price of the KM  Interest  shall  equal the Fair  Value of the KM
Interest  (A) times 135% if the Purchase  Notice is  delivered  during the fifth
year;  (B) 125% if the Purchase  Notice is delivered  during the sixth year; (C)
115% if the Purchase  Notice is delivered  during the seventh year; or (iv) 105%
if the  Purchase  Notice is  delivered  during the eight or any later year.  The
Appraised Value shall be determined using the facts and  circumstances  known as
of the effective date ("Valuation Data") including:

         (1) a reserve report of all CO2 reserves; 
         (2) all contracts in force on such date;
         (3) the most recently  approved  five year budget;
         (4) the planned  capital  expenditures;
         (5) any  proposed  future  projects or business opportunities   then   
             known  to  and   under evaluation by the Partnership; and
         (6) other factors  material to a determination of the future cash flow
             to the Partnership from the operations of its CO2 business.

     Using the Valuation  Data, the Valuation  Consultants  shall  calculate the
"Appraised Value" of the KM Interest. For purposes of computing Appraised Value,
the following factors shall be considered:

         (1)  cash   available   for   distribution  from   continuation of then
              existing operations;

                                       -90-
<PAGE>


         (2)  cash available for distribution expected (on a risk adjusted basis
              taking  into  account  which  projects,  if any,  are likely to be
              approved,  funded and completed as economically  successful) to be
              generated  from  future  capital   projects  known  to  and  under
              evaluation by the Partnership;
         (3)  cash used to fund future capital projects, based on the assumption
              that KM agreed to participate  in each future capital  project and
              that all future capital  projects are funded from a combination of
              cash available from  operations (as permitted by this  Agreement),
              equity contributions and Partnership Indebtedness as determined by
              the Valuation  Consultants based on the then current financial and
              other market conditions; and
         (4)  other  factors   affecting  cash  availability  and  value  of  KM
              Interest.

     Using the computation of cash available for  distribution to Partners,  the
Valuation  Consultant shall compute cash available for distribution to KM as the
cash available for distribution to Partners  multiplied by the Interest of KM in
the Partnership as of the effective date.

     Using the cash available for  distribution to KM, the Valuation  Consultant
shall compute a net present value of such distributions as of the effective date
based on a discount rate equal to the Yield on KM Units on the  effective  date.
For this purpose,  the Yield on KM Units shall equal the rate of return provided
to holders of the publicly  traded  partnership  units of Kinder  Morgan  Energy
Partners,  L.P. by referring to the cash  distribution  made during the previous
calendar  quarter  annualized  and compared to the average of the daily  closing
market  prices of the KM Units  during the sixty (60)  trading days prior to the
effective  date.  Such net present value shall be deemed the Appraised  Value of
the KM Interest.

     On or before the date sixty (60) days after the effective date, Shell shall
deliver to the Valuation Consultants and to KM a description of the terms of the
Payment Obligation proposed by Shell. The Valuation Consultants shall conduct an
evaluation of the net present value of the expected cash distributions as of the
effective  date from the Payment  Obligation  as proposed by Shell.  Shell shall
adjust the terms of the Payment Obligation until in the opinion of the Valuation
Consultants  the  net  present  value  of such  Payment  Obligation  equals  the
Appraised Value of the 
                                       -91-
<PAGE>


KM Interest.  The Valuation  Consultants shall compute such net present value of
the expected  cash  distributions  from the Payment  Obligation,  using the same
discount rate used to compute the Appraised Value of the KM Interest.

     The Valuation  Consultants shall deliver to KM and to Shell the computation
of  Appraised  Value  and  their  valuation  of  the  Payment   Obligation  (the
"Valuation"),  no later than the date 120 days after the effective date.  During
the period through the 160th day after the effective date, Shell agrees to cause
the Valuation Consultants to evaluate any suggested modifications to the payment
structure of the Payment  Obligation that may be provided by KM to Shell.  While
Shell is not  obligated  to accept any of such  modifications,  Shell  agrees to
consider such  modifications  and to provide KM with an  opportunity  to discuss
such modifications with Shell and the Valuation Consultants. If Shell and KM are
unable to agree as to all  aspects of the  Payment  Obligation  on or before the
170th day after the effective date, the Purchase Price shall be payable by Shell
in cash.

     (iv) Payment  of Purchase  Price.  Within twenty(20) business days from the
delivery  of the  Valuation,  KM shall  deliver  to Shell a  notice  of  Payment
selection.  KM shall elect either to receive  100% of the Purchase  Price (i) in
cash on the  closing  date of the  purchase  of its  Interest  by  Shell or (ii)
through  delivery by Shell or a  financially  responsible  Affiliate  of Shell a
written Payment  Obligation.  The option to request a Payment Obligation in lieu
of cash is a personal  right of KM that is not  transferable  to any  successor.
Accordingly,  any successor to a KM Interest shall not have the option to accept
a Payment  Obligation.  Shell may in its  absolute  discretion  deliver  to such
successor  payment  in  cash  or if KM  has  selected  payment  through  Payment
Obligation,  Shell may elect to pay such successor  through  delivery of Payment
Obligation.

     (v) Payment  Obligation.  The Payment  Obligation  shall  terminate  on the
fifteenth  Anniversary.  At Shell's  election,  the Payment  Obligation shall be
evidenced by:

              (A) a  non  operating interest, such  as a  volumetric  production
                  payment,  burdening   one  or  more   specific  CO2  producing
                  properties;


                                       -92-
<PAGE>


              (B) a  payment  obligation   computed  with  reference  to  a  non
                  operating interest,  such as a volumetric  production payment,
                  burdening one or more specific CO2 producing properties; or
              (C) such  other  form  of  payment  obligation  mechanism  that is
                  acceptable to both Shell and KM.

shall not affect the validity or legality of the  remainder  of this  Agreement.
The  preceding  sentence of this  Section 14.5 shall be of no force or effect if
the  consequence  of  enforcing  the  remainder of this  Agreement  without such

     This Agreement may be executed in any number of counterparts  with the same
effect as if all of the Partners had signed the same document.  All counterparts

     Each Partner  agrees with the other  Partners that the other Partners would
be  irreparably  damaged  if any of the  provisions  of this  Agreement  are not

                 PROCEDURES FOR COMPUTING INITIAL ADJUSTMENT AMOUNT

Accounting

     Within 90 days after the date of the Agreement ("Closing Date"), each of KM
and Shell shall  deliver to the other an  accounting  of the Initial  Adjustment
Amount,  which shall be  computed  as  provided  in this  Exhibit B. The Initial
Adjustment  Amount  for  each of Shell  and KM  shall  equal  the  results  from
operations (i.e. the difference  between revenues and expenses) of each of Shell
and KM (and their  respective  Affiliates as required to capture the  accounting
data for the assets and operations  initially  contributed  to the  Partnership)
covering  the period from  January 1, 1998 to the last day of the month prior to
the Closing Date ("Accounting Period").  Revenues and expenses shall be computed
in accordance with GAAP on the basis consistent with prior periods and shall not
include any sales of CO2, transportation charges or other fees between Shell and
KM.  All  overhead  expenses  associated  with  the  assets  contributed  to the
Partnership  shall be computed  using costs and  methods  consistent  with those
included in the five-year Operating Budget.

Review and Audit of Computation

     Within 90 days after Closing Date the Shell and KM Parties  shall  exchange
their computations of the Initial Adjustment Amount, following which there shall
be up to a 30 day review  period.  Each party at its own expense  shall have 120
days to review and audit the other's computation.  Such audit shall be conducted
so as to cause a minimum of inconvenience to the audited party. In the event any
dispute arises from the audits, the dispute shall be resolved in accordance with
Section 14.14.

         possession, maintenance, operation or abandonment of the Shell Assigned
         Assets prior to the Effective  Date (i) that are identified in Schedule
         3.1 hereto,  or (ii)  anticipated to exceed $100,000 of which the Shell
         Executive  Officers  had  knowledge  and failed to  disclose  to the KM
         Parties  prior to the  Closing  Date.  The  amount of any  Shell  Claim
         relating to a Shell Retained Matter  described in this Subsection 3.1.1

         to the  Effective  Date and does not extend to  liabilities  or damages
         accruing or  attributable  to time periods  subsequent to the Effective
         Date, even though such liabilities or damages may arise out of the same
         Shell  Claim which is the subject of a Shell  Retained  Matter.  To the
         extent a Shell  Retained  Matter  described  in this  Subsection  3.1.1

         Texas general partnership ("Cortez"), or any one or more of its general

         liens,   judgments,   settlements,   suits,  fines,   penalties  and/or
         compliance  costs (and any costs,  expenses and/or fees associated with

         including,  without  limitation,  reasonable  attorney's fees and legal
         costs) paid by Cortez; provided, however, to the extent such claims are
         not satisfied in full from the partnership

         assets of Cortez,  the amount of any Shell Claim shall further  include
         any and all additional  amounts directly or indirectly  incurred by the
         Limited  Partnership  as a general  partner of Cortez.  As used in this
         Subsection  3.1.1,  and with  respect to any Shell  Claim,  "knowledge"

   3.1.2 all  liabilities  under,  or  claims  for benefits by current or former
         employees   and/or   participants   of  the  Shell   Parties  or  their
         predecessors  (including the eligible dependents or other beneficiaries
         of such employees and/or  participants)  under, Shell Employee Benefits
         Plans,  whether or not such events are reported or unreported as of the
         Effective Date;

   3.1.3 all  liabilities  with  respect  to claims for, or in connection  with,
         post-retirement    coverage,    including,    but   not   limited   to,
         post-retirement  medical,  dental or life  insurance  coverages  by any
         current or former  employees  and/or  participants  of any of the Shell
         Parties or its predecessors (including the eligible dependents or other
         beneficiaries  of such employees and/or  participants)  under the Shell
         Employee Benefits Plans; and

   3.1.4 all  liabilities  with  respect  to  Taxes  (as  defined  in the Master
         Agreement  and  hereinafter  referred to as the  "Taxes") of any one or
         more of the Shell Parties  accruing or relating to periods prior to the
         Effective  Date  and  relating  to  the  use,  ownership,   possession,
         maintenance,  operation or  abandonment  of the Shell  Assigned  Assets
         prior to the Effective Date; and

   3.1.5 payables  with  respect  to expenses  incurred in  connection  with the
         operation of the Shell  Assigned  Assets and that accrued  prior to the
         Effective  Date,  (but excluding  matters  referred to in Section 2.2.1
         (f)).

The Limited  Partnership does not assume the Shell Retained  Matters.  All Shell
Retained Matters shall remain the responsibility of the Shell Parties. THE SHELL
PARTIES SHALL DEFEND, INDEMNIFY AND HOLD HARMLESS THE LP INDEMNIFIED PARTIES AND
THE  KM  INDEMNIFIED  PARTIES  FROM  AND  AGAINST  ALL  SHELL  RETAINED  MATTERS

         maintenance,  operation or abandonment of the KM Assigned  Assets prior
         to the Effective  Date (i) that are  identified in Schedule 3.2 hereto,
         or (ii)  anticipated  to  exceed  $100,000  of which  the KM  Executive
         Officers had knowledge and failed to disclose to the Shell

<PAGE>


         Parties prior to the Closing Date.  The amount of any KM Claim relating
         to a KM Retained Matter  described in this Subsection  3.2.1 is limited
         to  liabilities  accrued or  attributable  to time periods prior to the
         Effective Date and does not extend to  liabilities or damages  accruing
         or attributable to time periods  subsequent to the Effective Date, even
         though such  liabilities  or damages may arise out of the same KM Claim
         which  is  the  subject  of a KM  Retained  Matter.  As  used  in  this
         Subsection  3.2.1, and with respect to any KM Claim,  "knowledge" means
         the personal actual knowledge of any KM Executive Officer;

   3.2.2 all  liabilities  under,  or claims  for  benefits by current or former
         employees and/or  participants of the KM Parties or their  predecessors

         post-retirement  medical,  dental or life  insurance  coverages  by any
         current  or  former  employees  and/or  participants  of  any of the KM
         Parties or its predecessors (including the eligible dependents or other
         beneficiaries  of such  employees  and/or  participants)  under  the KM
         Employee Benefits Plans; and

   3.2.4 all  liabilities  with  respect to  Taxes  of any one or more of the KM
         Parties accruing or relating to periods prior to the Effective Date and
         relating to the use, ownership, possession,  maintenance,  operation or
         abandonment of the KM Assigned Assets prior to the Effective Date.

         operation  of the KM  Assigned  Assets  and that  accrued  prior to the
         Effective  Date,  (but excluding  matters  referred to in Section 2.2.1
         (f))

The Limited Partnership does not assume the KM Retained Matters. All KM Retained
Matters shall remain the responsibility of the KM Parties.  THE KM PARTIES SHALL

undisputed portion within (60) days, or such other mutually agreeable period, of

Party and shall take those actions reasonably within its power to take which are
reasonably  necessary  to preserve  any legal  defenses to  indemnified  matters
hereunder until the indemnifying Party has assumed the defense of the matter.

understandings,  whether  oral or  written,  relating  to such  subject  matter,
including the terms of any of the  Transaction  Documents to the extent the same

shall constitute one and the same agreement.

6.8 No Rights in Third Parties;  No Third Party  Beneficiaries.  This Agreement,
among other  things,  is intended to allocate  certain  risks,  obligations  and
potential obligations as among the Parties. The provisions of this Agreement are
for the sole  benefit of the Parties and are not  intended to create,  and shall
not create, any rights in any persons other than the Parties. There is no intent
that any Third Party should benefit from any provisions hereof, and no statement
herein as to Claims,  Environmental  Claims or Environmental  Cleanup  Liability
shall  constitute  any  admission  by  any  Party.  SPECIFICALLY,   BUT  WITHOUT
LIMITATION,  NO AGREEMENT TO INDEMNIFY, NO DETERMINATION OF RESPONSIBILITY,  AND
NO  APPORTIONMENT  OF  RESPONSIBILITY  HEREIN OR UNDER THE  TERMS  HEREOF  SHALL
CONSTITUTE  ANY  ACKNOWLEDGMENT  OR ADMISSION OF FAULT OR LIABILITY BY ANY PARTY
HERETO OR AS TO ANY THIRD PARTY.

punitive  damages  from the  other  Parties  for  breach  or  violation  of this
Agreement and each Party hereby waives any claim or right to special, exemplary,
consequential or punitive damages hereunder; provided, however, the

                                       20
<PAGE>


foregoing shall not limit any indemnification  obligations hereunder or preclude
one Party from being  indemnified by another Party against such types of damages
in the event  they are  awarded  against a Party and such Party is  entitled  to
indemnification pursuant to the terms of this Agreement.

6.10 Audit Rights. The Parties hereto reserve the right to perform audits of all
reimbursable costs,  billed by any Party to another,  which relate to the rights
and obligations set forth in this Agreement.  The billing Party shall retain all

documentation  shall be made  available for  inspection by the billed Party upon
request. Audits shall be performed within 180 days of submittal of any billings.
Any  disputes  arising  from  audits  shall be  handled in  accordance  with the
provisions of Article 5 hereof.

records  of the  Limited  Partnership  as they may  reasonably  require  for (i)
defending  or  evaluating  any  claims,  causes  of  action,   demands,   suits,
proceedings,  governmental  investigations or audits, losses, liability,  liens,
settlements,  judgments,  assessments, fines, penalties or administrative orders
