                        FINANCING OF OLEODUCTO CENTRAL

          Section 5.1.       Financing Plan; Financing Committee.  (a)(i)
Unless otherwise agreed by the Shareholders, the plan for the sources and
amounts  of financing for the acquisition, construction and development of the
Oleoducto  Central, including capitalized interest (as the same may be amended
from time to time in accordance with the terms hereof, the "Financing Plan"), is
currently expected to be based on the following proportions of debt and
equity:

</TABLE>
The  current  indicative terms of the Financing Plan are set forth in Schedule
F.

            (ii)     The Shareholders agree that the capitalization of the JSC
shall  consist  of  approximately 70% Senior Debt and approximately 30% Equity
Contributions  and  Pre-Completion  Accrued  Returns when the financing of the
Oleoducto Central is completed. The Shareholders agree that as nearly as
possible such Senior Debt and Equity Contributions should be funded in
accordance  with  the uses of funds set forth in the Financing Plan as amended
from  time  to  time.   Prior to completion of such funding, the Parties shall
cooperate  in  order to maintain the JSC's capitalization as close as possible
to 70% Senior


<PAGE>
Debt and 30% Equity Contributions and Pre-Completion Accrued Returns, but
recognize  that during the construction of the Oleoducto Central (i) until the
first  borrowing of Senior Debt by the JSC, the capitalization of the JSC will
be  100%  Equity Contributions and Pre-Completion Accrued Returns and (ii) the
timing  of  borrowings of Senior Debt by the JSC will cause the capitalization
of the JSC to vary.  The Shareholders agree that unless the JSC has been
successful  in  achieving a percentage of Senior Debt equal to at least 60% of
its  then  existing capitalization by the later of one year from execution and
delivery  of  the Project Agreements and April 1, 1996 (unless construction of
the Oleoducto Central has been delayed in which case such date shall be
extended by a corresponding amount of time), a Special Committee of
Shareholders  or  of the Board of Directors shall be established to review and
modify  the  Financing  Plan in a manner acceptable to Shareholders holding at
least  90.41% of the outstanding Shares. In this regard consideration shall be
given to requesting Initial Shippers to provide loans in order to increase the
proportionate  share  of the JSC's capitalization represented by Senior Debt.
Such loans shall be deemed to be Senior Debt.

          (b)  The Board of Directors may establish a financing committee (the
"Financing  Committee"), which shall be composed of one member representing each
Shareholder or an Affiliate thereof, together with the officer of the JSC
responsible for finance, and shall report to the Board of Directors.  The
Financing Committee shall have the following responsibilities:

       (i)  to update the Financing Plan at least quarterly based on actual to
date  Project Cost and to review and update Project Cost forecasts as provided
by the PCMT Manager;

     (ii)  to revise the forecast funding requirements of the JSC for the
subsequent four quarters on a quarterly basis;

     (iii)  to coordinate the funding of Senior Debt by the JSC to ensure that
the JSC obtains Senior Debt and Equity Contributions on a timely basis in
accordance with the then current Financing Plan; and

       (iv)  to provide the Shareholders with a schedule of specific projected
Senior  Debt  and Equity Contribution funding requirements (including the date
or  dates  such funding is required and the amounts thereof) at least 105 days
in advance of the date any such funding is expected to be required.

The Committee's decisions shall be in the form of recommendations to the Board
of Directors.

          (c)  Each Initial Shipper agrees to notify the JSC and the Financing
Committee of its intention to assist the JSC in arranging Senior Debt at least
90  days  in  advance  thereof and to provide them on a quarterly basis with a
non-binding  estimate  of  funding  sources for the subsequent four quarters.
Without the consent of Ecopetrol, each of BP Pipelines and TOTAL Pipeline
severally agrees that neither it nor any Affiliate will arrange for any Senior
Debt  of  the  JSC  with respect to the Senior Debt Tranche (as defined below)
attributable to it to be raised in the public or private markets for
securities transactions.

<PAGE>
          (d)  If, by December 31, 1995, the Shareholders determine that it is
not  possible  to achieve a capitalization of the JSC on the basis of the then
current  Financing  Plan,  the Shareholders will decide by holders of at least
90.41% of the outstanding Shares that each Shareholder or any of its
Affiliates will either:

     (i)  support the JSC in arranging debt by either arranging loans provided
by such Shareholder or an Affiliate on a several basis, or supporting the
making  of  such loans by third parties, so that the capitalization of the JSC
then consists of 70% Senior Debt and 30% Equity Contributions and
Pre-Completion Accrued Returns; or

     (ii)  increase its Equity Contributions pro rata to its Shareholding
Interest so that the resulting capitalization of the JSC consists of
approximately  60% Senior Debt and 40% Equity Contributions and Pre-Completion
Accrued  Returns.  Such  Equity Contributions shall consist of the purchase of
Shares  for  cash or, if the Parties otherwise unanimously agree, the purchase
of either a combination of Shares and Subordinated Notes for cash or
Subordinated  Notes  for cash, but only if the projected annual return on such
Equity  Contributions calculated in accordance with Section 5.4(b) is at least
13.5% after payment of all Colombian Taxes.

             (e)  In the event that the Financing Plan as amended from time to
time reflects an estimated Project Cost that exceeds by more than $50 million,
the original estimated Project Cost set forth in the Financing Plan in
Schedule  F  to this Agreement as originally signed then the JSC shall convene
an  emergency  meeting  of the Board of Directors as soon as practicable after
the  release of such amended Financing Plan to discuss methods of funding such
increase in cost.

             Section 5.2.       Senior Debt.  (a)  The Shareholders agree that
the JSC shall borrow Senior Debt from a combination of export credit agencies,
suppliers'  financing,  commercial  banks, public and private capital markets,
and  Shareholders  and  their Affiliates.  The Shareholders recognize that the
precise  allocation  of the JSC's borrowings of Senior Debt among such sources
will  depend  upon a number of factors, including, without limitation, capital
market conditions, the availability, terms and conditions of financing
provided or supported by export credit agencies, and the availability of
financing provided or arranged by Shareholders and their Affiliates.  The
Shareholders agree that the Financing Plan will be designed so as not to
jeopardize  the  existing  and future financing raised and to be raised by the
Initial  Shippers  with respect to the exploration, development and production
of the Fields.  Each Shareholder also agrees to cause its Affiliate that is an
Initial Shipper to design any future financing for such exploration,
development  and  production  in such a manner as to not materially jeopardize
the Financing Plan.

          (b)(i)  The JSC shall be the borrower of all Senior Debt included in
the Financing Plan.  The Senior Debt, including the loans contemplated in
Sections  5.1(d)(i),  shall  be borrowed by the JSC in four tranches of Senior
Debt (each, a "Senior Debt Tranche") provided by four separate groups of
Senior Lenders (each, a "Senior Lender Group").  Each Senior Debt Tranche
shall be separately secured by Collateral consisting of obligations of a
single Initial Shipper Group.

<PAGE>
          (ii)  All Senior Debt shall rank pari passu with respect to the
Collateral  securing Senior Debt within a particular Senior Debt Tranche.  The
Parties agree that each Senior Lender Group will have no recourse to any
assets  or  rights  of the JSC other than the Collateral separately supporting
the  related  Senior Debt Tranche.  The JSC agrees not to assign its rights in
any  agreements  or grant any security interests in any of its assets in favor
of any Senior Lender Group other than the Collateral separately supporting the
related Senior Debt Tranche which shall be used solely to support such
Tranche.    The  Parties agree to structure the Senior Debt so that the rights
and  remedies  of  each  Senior Lender Group will be entirely separate and the
exercise of rights and remedies by one Senior Lender Group against the
Collateral separately supporting the related Senior Debt Tranche will not
entitle any other Senior Lender Group to exercise any rights and remedies
against  its  Collateral or the Collateral of any other Senior Lender Group or
against any other assets or rights of the JSC.

          (iii)  The Parties agree that the common terms and conditions
applicable  to all Senior Debt and Senior Lender Groups and within each Senior
Debt  Tranche  shall  be  included in the Common Security Trust Agreement, and
that  all provisions specific to an individual borrowing or issuance of Senior
Debt under a particular Senior Debt shall be included in the Senior Debt
Agreement with respect to such borrowing or issuance.

          (c)(i)  The JSC agrees with each Shareholder to use reasonable
commercial  efforts  to  obtain  Senior Debt from Senior Lender Groups in such
amounts  and  at  such times as set forth in the then current Financing Plan.
Senior Debt provided by a Senior Lender Group shall have (i) an annual
interest  rate  or  interest rate formula at the time of borrowing of not more
than  600  basis  points  above the U.S. Treasury note of comparable maturity,
(ii)  a  term to maturity of not less than seven years nor more than 15 years,
(iii)a  principal  repayment  profile starting not later than six months after
the  Completion  Date  and  which is, for any six month period for each Senior
Debt  Tranche of an Initial Shipper Group, at least equal to its Proportionate
Share  of  Non-Cash  Items included in tariffs projected to be received by the
JSC  in  such  period  as determined in accordance with the Tariff Principles,
(iv) such terms and conditions (insofar as such terms apply to the JSC) as set
forth  in  the  Common Security Trust Agreement, and (v) such additional terms
and conditions to be set forth in the Senior Debt Agreement with respect
thereto as may be agreed by the person that has been nominated for election as
director  by the Shareholder whose Subscription Agreement is to be assigned by
the  JSC  for the benefit of such Senior Lender Group and to whom authority to
negotiate such Senior Debt Agreement is delegated by the Board of Directors in
accordance  with the By-Laws and this Agreement, provided that such additional
terms are not in conflict with this Agreement, the Common Security Trust
Agreement and all other Financing Agreements entered into by the JSC, the
Shareholders, the Initial Shippers and their Affiliates, and do not jeopardize
in  any  material respect future financings of the JSC.  If there is a dispute
as  to  whether  the  proviso to the preceding sentence has been breached, the
Board  of  Directors  of  the JSC shall determine whether any such conflict or
jeopardy exists.  In addition, any such additional term, or change in the term
of any Financing Agreement, which materially adversely affects the 13.5%
annual  return to the Canadian Group set forth in Section 5.4(b) shall require
the consent of the Canadian Group.

<PAGE>
          (ii)  All fees incurred on or prior to the date of the first
drawdown in connection with obtaining finance from a Senior Lender Group
(including,  without limitation, commitment fees, upfront fees, advisory fees,
underwriting  fees,  administration  fees,  insurance premiums, exposure fees,
management  fees,  and  facilities fees) shall be for the account of the JSC.
Such fees may be charged by an Affiliate of an Initial Shipper Group
Shareholder and may approximate the similar fees that may be charged in
respect of any other Senior Debt Tranche provided by third parties.
     (iii)  The JSC agrees, and each Shareholder that is a member of an
Initial Shipper Group agrees to cause each of the other members of its Initial
Shipper Group to agree, to use its best efforts to assist the JSC in obtaining
Senior Debt as nearly as possible in accordance with the uses of funds
identified  in  the "Use of Funds" table in the then current Financing Plan so
that  borrowings  of  Senior  Debt by the JSC will be made on a pro rata basis
from each Senior Lender Group.  In the event that such pro rata borrowings are
not  possible  due  to  capital market conditions or other factors and the JSC
raises  Senior Debt under the Senior Debt Tranche secured by the Collateral of
a  particular Initial Shipper Group prior to the time that such Senior Debt is
required  in accordance with such table, then (A) for the period of six months
following  the  first  date on which additional interest expense in respect of
such  Senior  Debt  is  accrued by the JSC, the JSC shall bear the cost of the
additional  after tax amount of interest expense on that amount of Senior Debt
which  is scheduled to be drawn to meet the requirement for funding identified
in the Financing Plan, during that six month period, and the Shareholder which
is a member of such Initial Shipper Group shall pay to the JSC the total
amount of the after tax interest expense (net of interest income earned by the
JSC)  above  such amount, and (B) for the period after such initial six months
the  relevant  Shareholder  shall pay to the JSC the total amount of after tax
interest expense (net of such interest income) on such Senior Debt.

          (iv)  If the JSC raises Senior Debt prior to the time that such
Senior Debt is required by the Use of Funds table in the then current
Financing Plan then each of the Shareholders which are not members of the
Initial Shipper Group whose Collateral has supported such Senior Debt may
require the JSC to raise or arrange on behalf of the JSC, Senior Debt
supported by the Collateral of the Initial Shipper Group of which it is a
member in order to preserve the pro rata basis for the raising of Senior Debt.
  In  this  event the terms of this Section 5.2(c) concerning the liability of
the  JSC  and such Shareholder for any additional interest expense incurred by
the JSC shall apply.

              (v)  Subject to the Financing Agreements, any drawings of Senior
Debt  which  is raised prior to the time it is required under the Use of Funds
table  in the then current Financing Plan shall be placed by the JSC in United
States Treasury bills or, at the option of the relevant Shareholder, in
short-term  (less  than 90 days) debt securities, commercial paper or treasury
deposits of its ultimate parent company which are rated A or better by
Standard & Poor's Corporation or the equivalent thereof by another
Internationally Recognized Statistical Rating Agency.

          (d)  In the event that the JSC, despite the use of its best efforts,
is unable to obtain commitments (formal or informal) for all or any portion of
the Senior Debt Tranche of an Initial Shipper Group, the JSC shall first
advise the Shareholder of such Initial Shipper

<PAGE>
Group  and each other Shareholder of the difficulties it is having and if such
difficulties  continue,  may thereafter (but not prior to the expiration of 30
days from such first advice), deliver to such Shareholder and each other
Shareholder  a  notice which shall specify the amount of such Senior Debt that
the  JSC has been unable to obtain (the "Senior Debt Shortfall") and the date on
which  such Senior Debt is required to be provided and disbursed to the JSC in
accordance  with  the  then current Financing Plan. Such notice of Senior Debt
Shortfall  must  be  provided by the JSC at least 45 days prior to such date.
The JSC and such Shareholder shall then meet and in good faith discuss
alternative bases on which such Senior Debt may be obtained, including,
without  limitation but subject to Section 5.2(c), changes or additions to the
agreements  being  assigned  for  the benefit of the proposed provider of such
Senior Debt.

           (e)  If such Senior Debt is not so disbursed to the JSC on or prior
to the date specified in the Senior Debt Shortfall notice, except as otherwise
provided in the Political Events Agreement, then (i) or (ii) shall apply:

         (i)  if (x) the total amount of Senior Debt supported by such Initial
Shipper  Group's Collateral that has been disbursed to the JSC as of such date
is  less than 85% of the aggregate Senior Debt Tranche to be supported by such
Initial  Shipper  Group's Collateral in the then current Financing Plan or (y)
the  sum  of  such  Senior Debt disbursed to the JSC plus Equity Contributions
made  by  such  Initial  Shipper Group as of such date is less than 85% of the
aggregate Senior Debt to be supported by such Initial Shipper Group's
Collateral  plus Equity Contributions to be made by such Initial Shipper Group
in such Financing Plan, the JSC shall apply the Transportation Agreement
Step-Up (as defined below) to the Initial Shipper in such Initial Shipper
Group and the applicable percentage shall be 250%.

        (ii)  if (x) the total amount of Senior Debt supported by such Initial
Shipper  Group's Collateral that has been disbursed to the JSC as of such date
is  greater  than  85% of the aggregate Senior Debt Tranche to be supported by
such Initial Shipper Group's Collateral in the then current Financing Plan and
(y) the sum of such Senior Debt supported by such Initial Shipper Group's
Collateral  disbursed  to  the  JSC plus the Equity Contributions made by such
Initial  Shipper  Group  as  of such date is greater than 85% of the aggregate
Senior  Debt  to  be supported by such Initial Shipper Group's Collateral plus
Equity Contributions to be made by such Initial Shipper Group in such
Financing  Plan, then the JSC shall apply the Transportation Agreement Step-Up
to the Initial Shipper of such Initial Shipper's Group and the applicable
percentage  shall  be 150%, provided that the 150% tariff increase shall apply
only  to  such  Initial Shipper's pro rata share of all Petroleum in excess of
185,000 barrels per day shipped by such Initial Shipper or on its behalf.

             (f)  The "Transportation Agreement Step-Up" shall mean the right of
the JSC in the Transportation Agreement with an Initial Shipper

<PAGE>
     (i)  to increase the tariff applicable to Petroleum shipped by such
Initial Shipper or on its behalf by a specified percentage of the tariff
originally  applicable under such Transportation Agreement for the shipment of
Petroleum (or to exercise any alternative right provided in the Transportation
Agreement  or  which  may  otherwise be available to it and which will achieve
substantially  the  same economic result), for a period beginning, in the case
of  Senior Debt, on the date specified in the notice of Senior Debt Shortfall,
and  in the case of an Equity Contribution shortfall, on the date specified in
the  call  for the Equity Contribution, and ending one year after the date the
Senior Debt Shortfall actually was remedied (whether by Initial Shipper Bridge
Loan  or  by obtaining Senior Debt from a third party which may be an existing
provider  of  Senior  Debt), in each case solely supported by Collateral other
than any other Initial Shipper Group's Collateral or any assets of the JSC) or
the Equity Contribution is made, and

       (ii)  for the remaining term of such Transportation Agreement, to apply
the highest of the tariff originally applicable in such Transportation
Agreement, the Third Party Tariff and the Overutilizer Tariff to that
proportion of capacity of each Segment for which such Initial Shipper was
entitled to pay the tariff originally specified in such Transportation
Agreement  represented  by the percentage amount that, in the case of a Senior
Debt Shortfall, is equal to the amount of the Senior Debt Shortfall divided by
the  aggregate amount of Senior Debt in the Senior Debt Tranche related to the
Initial  Shipper under such Transportation Agreement and the maximum amount of
Equity  Contributions  set  forth in the Subscription Agreement of the related
Shareholder, in each case as shown in the then current Financing Plan, and, in
the  case  of  a failure to make an Equity Contribution, is the amount of such
Equity Contribution divided by the same denominator.

The incremental tariffs payable by such Initial Shipper included in the sum of
(i)  plus  (ii)  above  which are above those tariffs otherwise payable, shall
accrue,  after  Colombian  Taxes,  to the party that provides funding for such
Senior  Debt  Shortfall  or Equity Contribution shortfall, and otherwise shall
accrue to the JSC.

          (g)  In order to fund a Senior Debt Shortfall with respect to Senior
Debt  to  be  supported by a given Initial Shipper Group's Collateral, the JSC
may  request  that  the  relevant Shareholder procure that its related Initial
Shipper  provide  a commitment to provide an Initial Shipper Bridge Loan on or
prior  to  the date specified in the notice of Senior Debt Shortfall.  If such
commitment is not obtained in 15 days or if the Initial Shipper Bridge Loan is
not  provided  on  the date the Senior Debt Shortfall is due, then the JSC may
request a Shareholder Bridge Loan (as defined below) provided that if the
Initial  Shipper  Bridge Loan is provided on or prior to the date specified in
the notice of Senior Debt Shortfall, and meets the full amount of such
Shortfall, the JSC shall accept the Initial Shipper Bridge Loan in lieu of any
Shareholder  Bridge Loan.  In any case, the JSC shall continue to try to raise
the Senior Debt Shortfall.

<PAGE>
           (h)  "Initial Shipper Bridge Loan" shall mean a bridge loan from an
Initial Shipper or an Affiliate of such Initial Shipper or a financial
institution on its behalf.  In such case, the Initial Shipper Bridge Loan
shall accrue interest at an annual rate equivalent to the annual interest rate
implied  by  the Benchmark Interest Expense, and shall mature not earlier than
the  then  average life of the outstanding Senior Debt Tranche of such Initial
Shipper.  If not replaced after 30 days, such Initial Shipper Bridge Loan
shall convert to a loan at the applicable rate implied by the Benchmark
Interest  Expense  and  such  Initial Shipper Bridge Loan shall be part of the
Senior Debt Tranche supported by such Initial Shipper Group's Collateral,
provided  that any changes which are necessary to comply with the terms of the
Common Security Trust Agreement are made in accordance with the terms thereof.

           (i)  "Shareholder Bridge Loan" shall mean a bridge loan provided by
one or more Shareholders or their Affiliates or one or more financial
institutions  on  their  behalf, at their option, which are not in default for
failing to make an Equity Contribution or are not a member of an Initial
Shipper Group with a Senior Debt Shortfall.  Such Shareholder Bridge Loan
shall bear interest at the rate specified in paragraph (h) above. If such loan
is not repaid within 90 days with the proceeds of a loan secured by the
Collateral supported by the Initial Shipper Group whose Shareholder is
associated  with  the Senior Debt Shortfall or, if the Shareholder Bridge Loan
has been provided to meet a failure to make an Equity Contribution by a member
of  an Initial Shipper Group, then the JSC shall exercise its rights under the
Transportation Agreement with the Initial Shipper in such Shareholder's
Initial  Shipper  Group to increase the tariff applicable to Petroleum shipped
by such Initial Shipper or on its behalf by 250% of the tariff otherwise
applicable for shipment of Petroleum in the event subsection 5.2(e)(i) or
5.3(b)(i)  is  applicable  and 150% of such amount if subsection 5.2(e)(ii) or
5.3(b)(ii)  is applicable, in each case for a period beginning, in the case of
a  Senior  Debt  Shortfall, on the date specified in the notice of Senior Debt
Shortfall,  and, in the case of a call for an Equity Contribution, on the date
specified  in  the notice of call for such Equity Contribution, and ending two
years following the repayment of such Shareholder Bridge Loan.  The
incremental tariffs payable by such Initial Shipper above those otherwise
payable shall accrue, after taxes, to the Shareholder that provides or
procures the provision of the Shareholder Bridge Loan.

     (j)If such Senior Debt Shortfall continues for 20 days following the date
of  such notice of Senior Debt Shortfall, an emergency meeting of the Board of
Directors  shall  be  convened  on a date at least five days prior to the date
specified in the notice of Senior Debt Shortfall to determine a method of
funding such Senior Debt Shortfall.  Such meeting need not be held if the
Senior Debt Shortfall is funded.

          Section 5.3.   Several Commitments of Shareholders to Make Equity
Contributions
(a)  Each  Shareholder  agrees to enter into a Subscription Agreement with the
JSC  providing  for  the  making of Equity Contributions in proportion to such
Shareholder's  respective  Shareholding Interest, upon the call of the JSC and
in  conformity  with  annual  Capital Budgets and Funding Resolutions, as such
funding  requirements  are updated by the Financing Committee in the Financing
Plan  and  to comply with the terms hereof.  The JSC agrees that any call made
by  it  for  the making of Equity Contributions by a Shareholder shall only be
made simultaneously with a call to all Shareholders and that the proceeds from
any  Equity  Contribution or payment under any Performance Guarantee Agreement
shall be

<PAGE>
used for capital expenditures to be incurred in connection with the
construction of the Oleoducto Central.

          (b)  If a Shareholder fails to make an Equity Contribution on a
timely basis, and such failure continues for 15 Business Days, then, except as
otherwise provided in the Political Events Agreement, (i), (ii) or (iii) shall
apply:

     (i)  if such defaulting Shareholder is an Initial Shipper or Affiliate of
an  Initial  Shipper  and  if (x) the total amount of Senior Debt supported by
such  Initial  Shipper  Group's Collateral and disbursed to the JSC as of such
date  is less than 85% of the aggregate Senior Debt Tranche to be supported by
such  Initial Shipper Group's Collateral in the then current Financing Plan or
(y) the sum of Senior Debt supported by such Initial Shipper Group's
Collateral  and  disbursed  to  the JSC plus Equity Contributions made by such
Initial Shipper Group as of such date is less than 85% of the aggregate Senior
Debt  to  be  supported by such Initial Shipper Group's Collateral plus Equity
Contributions to be made by such Initial Shipper Group in such Financing Plan,
the JSC shall apply the Transportation Agreement Step-Up to the Initial
Shipper  in  such Initial Shipper Group and the applicable percentage shall be
250%;

     (ii)  if such defaulting Shareholder is an Initial Shipper or an
Affiliate  of  an  Initial  Shipper and if (x) the total amount of Senior Debt
supported  by such Initial Shipper Group's Collateral and disbursed to the JSC
as of such date is greater than 85% of the aggregate Senior Debt Tranche to be
supported by such Initial Shipper Group's Collateral in the then current
Financing Plan and (y) the sum of Senior Debt supported by such Initial
Shipper  Group's Collateral and disbursed to the JSC plus Equity Contributions
by  such Initial Shipper Group made as of such date is greater than 85% of the
aggregate Senior Debt to be supported by such Initial Shipper Group's
Collateral  plus Equity Contributions to be made by such Initial Shipper Group
in such Financing Plan, the JSC shall apply the Transportation Agreement
Step-Up to the Initial Shipper in such Initial Shipper Group and the
applicable  percentage shall be 150%, provided that the increased tariff shall
only  apply to the Initial Shipper's pro rata share of all Petroleum in excess
of  185,000  barrels per day shipped by such Initial Shipper or on its behalf;
or

     (iii)  if such defaulting Shareholder is IPL Enterprises or TCPL
International  or  any successor or assign thereto, the JSC shall exercise its
right to cancel partially or entirely payment of operating, incentive and
other  fees  payable  under  the Oleoducto Central Operations Agreement at the
direction  of  the  Initial  Shippers for a period of up to five years, and if
such  default  continues for more than 90 days the JSC shall have the right to
terminate  such Oleoducto Central Operations Agreement without compensation to
(and  without  prejudice  to its accrued rights against) the Operator (in each
case except to the extent provided in the Political Events Agreement).

<PAGE>
          (c)  In order to avoid a failure by a Shareholder to make any Equity
Contribution, if the JSC has any reasonable grounds to believe that such
Shareholder  may not be able to make such Equity Contribution, the JSC may, 45
days before an Equity Contribution is due, request a commitment to make a
Shareholder Bridge Loan on the date of the Equity Contribution.  If no
Shareholder Bridge Loan Commitment is made or if such Bridge Loan is not made,
or  if  such  Bridge Loans do not cover the shortfall in Equity Contributions,
the JSC may request that other Shareholders, at their option, fund such Equity
Contributions in return for Shares.  If more than one non-defaulting
Shareholder chooses, at its option, to participate in such Equity Contribution
then such Shares shall be sold pro rata to each such non-defaulting
Shareholder  choosing to participate or otherwise as they may mutually agree.
In such a case, such default shall not be deemed to be cured.

          (d)  If the JSC continues to believe for any reason that a
Shareholder may not be able to make an Equity Contribution on time, an
emergency  meeting  of  the  Board of Directors shall be convened on a date at
least five days prior to the date specified in the notice of call for an
Equity Contribution to determine a method of funding such anticipated
shortfall.  Such meeting need not be held if the Equity Contribution shortfall
is funded.

          (e)  In the event there is a Senior Debt Shortfall or a shortfall in
Equity Contributions for purposes of Section 5.2(e) or 5.3(b), as the case may
be, any Accrued Return accumulated for the benefit of the non-funding
Shareholder or any of its successors or assigns after occurrence of such
Senior  Debt  Shortfall  or shortfall in Equity Contributions, as the case may
be,  will  accumulate for the benefit of and ultimately be paid to the parties
which  have  provided funding under Section 5.2(g) or 5.3(c) until the failure
is  cured,  all  in accordance with the terms of the Dividend Trust Agreement;
provided that, in case of suspension of the non-funding Shareholder's Purchase
Obligation and application to it of the OCA Remedies under the Political
Events  Agreement  (as  those  terms are defined therein), any Accrued Returns
accrued prior to such suspension will accumulate for the benefit of the
non-funding  Shareholder or any of its successors or assigns and any dividends
accumulated  thereafter  will  accumulate for the benefit of and ultimately be
paid  to,  in  the  first instance, the other Shareholders which have provided
funding pursuant to the Political Events Agreement and thereafter to any other
party which has provided funding under Section 5.2(g) or 5.3(c).

          Section 5.4.       Returns to Shareholders (a)  Subject to the
requirements  of  any  Financing Agreements, all the cash generated by the JSC
from operating and investing activities shall be applied in the following
order in any year:

      (i)  to pay Operating and Maintenance Costs and Colombian Taxes incurred
during such year;

     (ii)  to pay interest incurred and scheduled principal payments on Senior
Debt during such year;

     (iii)  to pay interest and principal on any loans made pursuant to
Section  5.1(d)(i),  Initial Shipper Bridge Loans and Shareholder Bridge Loans
made pursuant to Section 5.2(g) or 5.3(c), if any;

<PAGE>
     (iv)  to pay interest incurred on, and Tariff guarantee fees with respect
to, Tariff Advances and Transportation Notes;

     (v)  to repay Tariff Advances and Transportation Notes;

        (vi)  to pay semi-annual cash dividends or distributions to or for the
account  of the Shareholders in accordance with paragraph (b) below, including
the Subordinated Fee, and to pay interest on Subordinated Notes referred to in
Section 5.1(d)(ii) issued in substitution for Shares;

         (vii)  to distribute annual Equity Amortization Amounts in accordance
with  Section  5.5  and  to pay principal of Subordinated Notes referred to in
Section  5.1(d)(ii)  issued  in substitution for equity (but not including any
Equity Amortization); and

       (viii)  to the extent of any remaining Available Cash, to repay Advance
Tariff Payments, and make other Distributions in accordance with Section 5.6;

     (ix)  to retire or repurchase any remaining outstanding Shares.

          (b)  The Parties agree that subject to Section 5.4(a), the
requirements of any Financing Agreements and applicable Colombian law, the JSC
shall  (i)  prior  to the date which is the earlier of the Completion Date and
December 31, 1998 (the "Dividend Commencement Date"), accumulate and
capitalize in each year a 13.5% annual return (net of all Colombian Taxes), on
the aggregate Cash Paid-In Equity and Pre-Completion Accrued Returns (as
defined herein and denominated in dollars) and (ii) subsequent to the Dividend
Commencement  Date pay a 13.5% annual return net of all Colombian Taxes on the
Adjusted Paid-In Equity (defined in Section 5.4(c) and denominated in
dollars).  Such return shall be calculated monthly and paid semi-annually
following the Dividend Commencement Date.  Such payment shall accrue any
Accrued  Return  accruing  after  the Dividend Commencement Date.  Such return
shall be paid by the JSC to or for the account of the Shareholders in
accordance with their Shareholding Interests in the form of Distributions (but
not including any Equity Amortization), in each case in conformity with Annual
Operating Budgets or as the Board of Directors and the Shareholders may
otherwise determine from time to time.

           (c)  For purposes of sub-section (b) above," Adjusted Paid-In Equity"
shall  mean  an  amount  determined as follows, regardless of the Cash Paid-In
Equity of the JSC:

        (i)  As of June 1, 1996 the "Target Project Cost" shall be unanimously
determined by the Shareholders.  Target Project Cost shall include only direct
costs  of the Oleoducto Central that are or may be properly capitalized on the
books of the JSC, including the estimated direct cost to complete the
Oleoducto  Central through the expected Completion Date in the form of a Class
I estimate provided by Brown & Root, Inc. or an Affiliate thereof or, if
different, the principal contractor at the time (including all direct historic
and projected costs, e.g., engineering, material and construction),

<PAGE>
     (ii)  Within 120 days after the end of the month in which the actual
Completion  Date  occurs,  the  Shareholders shall determine the actual direct
completion cost of the Oleoducto Central as of such month end on the same
basis as set forth in clause (i) above ("Actual Project Cost").

     (iii)  Within 30 days after the determination of the Actual Project Cost,
the  Shareholders shall compute the "Agreed Project Cost."  The Agreed Project
Cost  shall  be  the Target Project Cost increased by any amounts arising from
material  and  equipment  defects, construction (workmanship) deficiencies and
capital costs with respect to any facility arising after the facility has been
commissioned,  and  increased  or decreased, as the case may be, by changes in
scope  of  work,  provided that if the Agreed Project Cost as so determined is
within  $50  million  of the Actual Project Cost, then the Agreed Project Cost
shall  be  the Actual Project Cost adjusted in any case for such cost variance
up to $50 million.

     (iv)  Within the time period specified in clause (iii) above, the
Shareholders shall also determine the percentage which the sum of Cash Paid-In
Equity and Pre-Completion Accrued Returns shall represent of the total
capitalization of the JSC which shall consist of the aggregate of
indebtedness,  Cash  Paid-In  Equity and Pre-Completion Accrued Returns of the
JSC as of the end of the month in which the
Completion  Date  occurs (the "Equity Percentage"). Should the Parties fail to
agree on the Equity Percentage, the Equity Percentage shall be the actual
percentage on such date as determined by the JSC's independent auditors.

      (v)  "Adjusted Paid-In Equity" shall be a dollar amount equal to the sum
of (x) Cash Paid-In Equity and Pre-Completion Accrued Returns and (y) the
product of (a) the Equity Percentage and (b) the difference between the Agreed
Project Cost and the Actual Project Cost e.g.,

Adjusted Paid-In Equity = Cash Paid-In Equity + Pre-Completion Accrued Returns
+ (Equity Percentage X (Agreed Project Cost - Actual Project Cost)).

              (d)  An example of the calculation of the Agreed Project Cost is
attached to this Agreement as Schedule I.

              (e)  Following the determination of the Adjusted Paid-In Equity,
such  annual  return to Shareholders shall be calculated and paid on the basis
of  Adjusted  Paid-In  Equity  as calculated above or, if applicable, Adjusted
Paid-In  Equity  decreased  to reflect amortization of the Cash Paid-In Equity
and  Pre-Completion  Retained Returns are amortized in accordance with Section
5.5.

          (f)  The Tariff Principles shall reflect, and the tariffs payable by
Initial  Shippers  shall be calculated to provide, the annual return on equity
set  forth  in paragraph (b) above based on Adjusted Paid-In Equity determined
as set forth in clause (v) of paragraph (c) above, subject to paragraph (e).

              (g) " Cash Paid-In Equity" shall mean a dollar amount equal to the
aggregate of all cash payments made in exchange for (i) Shares or other
capital stock of the JSC pursuant

<PAGE>
to the Subscription Agreements and (ii) Subordinated Notes pursuant to
subscription agreements substantially in the form of the Subscription
Agreements.

          (h) " Pre-Completion Accrued Returns" shall mean a dollar amount equal
to a 13.5% annual return (net of all Colombian taxes) accumulated, capitalized
and  compounded  by  the  JSC in each year prior to the Completion Date.  Such
returns shall be calculated on the aggregate of prior balances of Cash Paid-In
Equity and Accrued Returns.

            (i)  "Accrued Returns" shall mean that amount of the annual return
referred to in paragraph (b) above which has not been paid and is accumulated,
capitalized and compounded.

             (j)  The right of a Shareholder to receive Distributions from the
JSC  shall  not constitute Collateral supporting any Senior Debt Tranche.  Any
reduction  in  amounts  available for Distributions due to a failure to make a
payment  or  a material default of a member of an Initial Shipper Group or its
successor or assign under any of the Financing Agreements or the related
Transportation Agreement shall, notwithstanding such reduction, not affect the
entitlement of Shareholders which are not members of a defaulting Initial
Shipper Group to receive, through the operation of the Dividend Trust
Agreement, their respective Shareholding Interest of the amount which, but for
the  default, would have been available for Distributions.  The Dividend Trust
Agreement  shall  provide that any Shareholder which is a member of an Initial
Shipper  Group  which,  through the default of any of its members has caused a
reduction in the amount available for Distributions, shall only be entitled to
retain the balance remaining of any Distributions after each of the other
Shareholders  has  received its respective Shareholding Interest of the amount
which,  but for such default, would have been available as Distributions.  The
Dividend Trust Agreement will further provide that Distributions receivable by
the  Shareholders  which  are  part of the defaulting Initial Shipper Group in
subsequent  periods  will  be redistributed pro rata to Shareholders which are
not part of the defaulting Initial Shipper Group so as to make up any
remaining  shortfall  in  the Distributions which such Shareholders would, but
for  such default, have been entitled to receive in the previous periods.  The
Dividend Trust Agreement shall give effect to the principles set forth in this
paragraph (j).

              Section 5.5.       Return of Equity Contributions.  (a)  The JSC
agrees  to  use all reasonable measures available to it under Colombian law to
effect the Equity Amortization under arrangements satisfactory to the
Shareholders  associated  with the Initial Shipper Groups, provided that there
is  no  obligation on the part of any Initial Shipper to produce Petroleum and
ship  it  if such Initial Shipper believes it would be uneconomic for it to do
so.

           (b)  Subject to paragraph (a) and the applicable Colombian law, the
equity capital of the JSC will be repaid pro rata to the JSC's shareholders by
making Distributions as follows:

        (i)  Subject to clause (ii) below and to the requirements of Colombian
law, no later than the last dividend date in respect of 2003 and no later than
such date in respect of each of the following nine years, the JSC shall make a
Distribution equal to the Annual Equity Amortization Amount; and

<PAGE>
       (ii)  The obligation to distribute an Annual Equity Amortization Amount
in  any  year  shall be suspended if the Equity Amortization Deferral Test for
that  year  is  satisfied, provided such distributions may not be suspended in
respect of 2012 or any year thereafter, and provided further that such
distributions shall not be suspended in any year in or after which the
Oleoducto Central Operations Agreement is not extended by its terms.

        (iii)  The "Equity Amortization Deferral Test shall be satisfied as to
any Equity Amortization Period if cumulative BITCF (as defined below) is
positive  for a period commencing at the beginning of such Equity Amortization
Period  and ending with the third calendar year after such Equity Amortization
Period and during which annual BITCF may be negative for no more than two
calendar years, provided that the second such year of negative annual BITCF is
followed by at least one year in which annual BITCF is positive.  The
determination  of whether BITCF meets the above standard is satisfied shall be
made as follows:

Such  determination  for any year shall incorporate both physical and economic
performance factors relating to Cusiana/Cupiagua reservoirs and any other
reservoirs  dedicated  to  the Oleoducto Central.  The physical performance of
the  reservoirs shall be based on an annual estimate of remaining economically
recoverable  reserves dedicated to the Oleoducto Central.  This estimate shall
be  proposed  by  the  JSC to the Board of Directors utilizing internationally
recognized  reservoir techniques.  If the Board of Directors fails to agree to
the estimate unanimously, the Board of Directors will engage an
internationally  recognized reservoir consulting firm to make a recommendation
on  physical  performance of the reservoirs to the JSC.  The information to be
presented to the Board of Directors shall include all currently available
reservoir  information such as geophysical, geological, production, pressures,
fluid  properties  and  historical  performance trends.  The information shall
also  include estimates of proved, probable and possible production forecasts,
risk  weighted  as appropriate.  The Equity Amortization Deferral Test for any
year  shall  include  all fields from which liquid hydrocarbons are reasonably
forecast  as  determined  by the Board of Directors, to be transported via the
Oleoducto Central.

       Based on this projection of future field(s) deliverability, an economic
(model) projection shall be developed using United States Securities and
Exchange  Commission  guidelines and operating expense and oil price scenarios
approved by the Board of Directors.  From the foregoing, an estimate of future
annual before income tax cash flow ("BITCF") is to be derived for
Cusiana/Cupiagua  and  any  additional reservoirs.  Such annual BITCF shall be
the total revenue to be derived from the field's sale of all liquid
hydrocarbons transported via the Oleoducto Central minus all actual or
forecast  expenses  required  to  deliver these liquids to Covenas and related
taxes, including but not limited to the following:

     the tariff charged by the JSC,
     all related field operating expenses, including but not limited to
     crude oil lifting and processing costs, water/gas reinjection costs,
overhead  charges, and any other expenses related to the operation      of the
field,

<PAGE>
     any special levies such as war tax,
     any contractual uses of cash such as interest on and principal
    repayment of outstanding (field) debt, and
     any presumptive/social taxes or other corporate burdens.

     (iv)  Payments of Annual Amortization Amounts shall be made annually.

          (c)  The term "Equity Amortization" refers to the process of
repaying equity described in paragraph (b) above.

          (d)  "Annual Equity Amortization Amount" means 10% of the Cash
Paid-In Equity and Pre-Completion Accrued Returns at the end of the year
preceding the first year in which Equity Amortization occurs, provided that in
the tenth and last year of Equity Amortization, the equivalent of 20,000
shares of the JSC's original capitalization shall be left outstanding.

             (e)  "Equity Amortization Period" shall mean a period of 10 years
less  the  number  of years as to which Equity Amortization Payments have been
made.

            Section 5.6.       Other Distributions.  (a) As of the last day of
each calendar quarter, and for each succeeding calendar quarter, after all the
payments  required  by  clauses (i) through (viii) of Section 5.4(a) have been
made  in  respect of such quarter, the JSC shall determine the amount, if any,
of  Available  Cash  which it is unable for legal reasons to pay as a dividend
(the "Cash Trap Amount").  During the subsequent quarter, the JSC shall
determine the interest earned on the Cash Trap Amount and record such interest
in  a  separate account.  Such interest and any interest earned thereon is the
"Cash Trap Interest".

            (b)  Any Shareholder which is a member of an Initial Shipper Group
may  direct  the  JSC  to invest that portion of the Cash Trap Amount equal to
such  Shareholder's  Proportionate Share in commercial paper, short term notes
(not  exceeding  90 days maturity) or treasury deposits of its ultimate parent
company  so long as such securities are rated A or better by Standard & Poor's
Corporation  or  the  equivalent thereof by another Internationally Recognized
Statistical Rating Agency.

            (c)  After the repayment in full by the JSC of Senior Debt, Tariff
Advances, Transportation Notes and Advance Tariff Payments, and upon the
determination  by  the Board of Directors that the JSC has Available Cash, but
is unable for legal reasons to pay dividends, the JSC may, based on the
financial statements of the JSC at the end of the prior semi-annual period, to
the  extent  that  it has Available Cash after making the payments required by
clauses  (i)  through (viii) of Section 5.4(a), pay out of such Available Cash
to  each  Shareholder which is a member of an Initial Shipper Group, (i) up to
such Shareholder's Proportionate Share of the sum in dollars of the Cash
Paid-In  Equity  and the Pre-Completion Accrued Returns less any Annual Equity
Amortization  Amount  previously  paid  plus the legal reserve required by the
Colombian Commercial Code (Reserva Legal) expressed in pesos, (ii) such
Shareholder's Proportionate Share of an amount equal to the Cash Trap Interest
taking into account the investment instructions given by such

<PAGE>
Shareholder  in  accordance with subsection (b) above, and (iii) to the extent
of the balance of such excess Available Cash, the amount of such excess
multiplied  by the fraction obtained by dividing the sum of (A) the cumulative
barrels of Petroleum shipped through the Oleoducto Central by the Initial
Shipper in the Initial Shipper Group of such Shareholder since January 1, 1996
and (B) the such Shareholder's Proportionate Share of third party barrels
shipped  during  the  same period, by total cumulative barrels shipped through
the  Oleoducto  Central during such period.  Such payment shall be by means of
any Distributions legally permissible under Colombian law, including the
capitalization  of  inflation adjustment reserves followed by Distributions to
Shareholders.

          Section 5.7.       Right of Set Off.  The Parties agree that the JSC
shall  have  the right, in its sole discretion, to set off against sums due by
it under any loan, note or credit for Advance Tariff Payments, Tariff Advances
or  Transportation Notes held by a Shareholder the unpaid amount of any Equity
Contribution with respect to which such Shareholder is in default.

             Section 5.8.  Senior Debt and Equity Contribution Shortfalls.  In
recognition of the serious consequences of any Senior Debt Shortfalls or
failures  by  a Shareholder to make Equity Contributions to the ability of the
JSC to construct and develop the Oleoducto Central and the difficulty of
ascertaining the damages that would result from such consequences, the
Shareholders recognize and acknowledge that the rights of the JSC under
Sections 5.2(e) and 5.3(b) are reasonable.  Furthermore, each Shareholder that
is a member of an Initial Shipper Group agrees to cause its associated Initial
Shipper  to  comply  with  its obligations under its Transportation Agreement,
including,  without  limitation, the obligations referred to in Section 5.2(e)
and Section 5.3(b).


                                 ARTICLE SIX

                  CAPITAL INVESTMENT AND SOLE RISK PROPOSALS

          Section 6.1.       Capital Investment Proposals.  (a)  Any
Shareholder  or  Shareholders may require the JSC to submit, at the expense of
the  proposing Shareholders, a proposal (a Capital Investment Proposal) to the
Board  of  Directors to add facilities to or modify any existing facilities at
any  Segment of the Oleoducto Central for the purpose of expanding capacity or
otherwise improving service.  A Capital Investment Proposal shall be submitted
to the Board of Directors only if the JSC, acting through the Operator,
certifies that such Capital Investment Proposal complies with all safety,
environmental and engineering standards of the JSC then in effect. The Capital
Investment  Proposal  shall be submitted together with all relevant details of
the proposed additional facilities or modifications to or in the existing
facilities,  the  estimated  cost thereof, the schedule for their construction
and entry into service and an estimate of the associated operational and
maintenance costs expected to be incurred during the lifetime of such
facilities.

<PAGE>
             (b)  The Board of Directors shall consider the Capital Investment
Proposal  and may cause the JSC to adopt such Capital Investment Proposal by a
unanimous  vote of the Board of Directors in accordance with the By-Laws as an
amendment  to the then current Capital Budget and by a vote of four of the six
members of the Board of Directors in accordance with the By-Laws as an
amendment  to  the then current Annual Operating Budget.  The JSC shall notify
the Shareholder of the Board of Directors' decision within 60 days of the date
on which the Capital Investment Proposal was submitted.

          Section 6.2.       Sole Risk Proposals.  (a)  If the Board of
Directors  does  not  approve  a Capital Investment Proposal submitted for its
consideration  by a Shareholder pursuant to Section 6.1, such Shareholder (the
"Sole Risk Party") may require the JSC to resubmit such Capital Investment
Proposal,  as it may be amended by the Shareholder, as a sole risk proposal (a
"Sole  Risk Proposal").  The Sole Risk Proposal shall be submitted together with
all relevant details of the proposed additional facilities or modifications to
or  in  the  existing facilities, the estimated cost thereof, the schedule for
their  construction  and  entry into service and an estimate of the associated
operational  and maintenance costs expected to be incurred during the lifetime
of  the  proposed facilities or modifications to existing facilities (the "Sole
Risk  Facilities").    A  Sole Risk Proposal shall be submitted to the Board of
Directors  only  if  the JSC, acting through the Operator, certifies that such
Sole  Risk  Proposal  complies  with all safety, environmental and engineering
standards  of  the  JSC then in effect.  The Board of Directors shall consider
the  Sole  Risk  Proposal and may, subject to its compliance with the criteria
established  in  Sections  6.4  through 6.8, approve the implementation of the
Sole Risk Proposal by a vote of four of the six members of the Board of
Directors in accordance with the By-Laws. The members of the Board of
Directors shall (and, if the matter is subsequently referred to a General
Meeting of Shareholders, the Shareholders shall) vote to approve the
implementation of the Sole Risk Proposal (subject to compliance with the
criteria  referred  to  above)  unless such implementation would prejudice the
rights  of any Shareholder or its Affiliate under the Project Agreements.  The
JSC shall notify the Sole Risk Party in
writing of the Board of Directors' decision within 60 days of the date on
which the Sole Risk Proposal was submitted.

          (b)  If the Board of Directors does not approve a Sole Risk
Proposal,  the JSC shall state in writing in reasonable detail the reasons why
the JSC did not approve such Sole Risk Proposal.

          (c)  If the Board of Directors does not approve a Sole Risk
Proposal,  the  Sole  Risk Party may require the JSC to submit an amended Sole
Risk Proposal provided that such Sole Risk Party follows the procedures
applicable to Sole Risk Proposals set forth in paragraph (a) above.

            Section 6.3.       Participation of Other Shareholders.  If a Sole
Risk  Proposal  is approved in accordance with Section 6.2, then the Sole Risk
Party shall, if it wishes to implement the Sole Risk Proposal, issue a written
notice  to  the  other  Shareholders and the JSC of its intention to proceed.
Such notice shall contain the Sole Risk Proposal together with all the
relevant  details  referred  to in Section 6.2.  Any Shareholder may within 45
days  of its receipt of such notice give written notice to the Sole Risk Party
and  the  JSC  of  its decision whether or not to participate in the Sole Risk
Proposal and if it decides to so

<PAGE>
participate it shall have the right to do so in such proportion as it and the
Sole Risk Party may agree.

           Section 6.4.       Implementation and Indemnity.  (a)  The Operator
shall  carry  out the construction operations in connection with any Sole Risk
Proposal  which  has  been  accepted unless the Board of Directors unanimously
agrees to permit the Sole Risk Party to carry out such construction
operations.

           (b)  The Shareholder or Shareholders participating in the Sole Risk
Proposal  with the Sole Risk Party (together, the Sole Risk Parties), pro rata
to  their  interests  in the Sole Risk Facilities, shall jointly and severally
indemnify the JSC, the Operator and the Initial Shippers that are not
Affiliates  of  Sole  Risk  Parties and hold them harmless against all losses,
claims, damages and liabilities in respect thereof arising prior to the end of
commissioning of the Sole Risk Facilities (but not consequential losses, other
than loss of or delay in receipt of revenue due to interruption in the
operation  of  the  Oleoducto  Central or any part thereof) after the JSC, the
Sole  Risk  Party and the Initial Shippers that are not Affiliates of the Sole
Risk Parties have made all reasonable efforts to avoid or mitigate such losses
or delays during the implementation of a Sole Risk Proposal.

          (c)  The JSC, in consultation with the Sole Risk Parties, shall
arrange  for  insurance  coverage  during the period of construction and entry
into  service for the Sole Risk Facilities on terms reasonably satisfactory to
the Board of Directors.

            (d)  All costs and expenses attributed by the JSC and the Operator
as  having  been  incurred by it in the implementation of a Sole Risk Proposal
shall be agreed with and for the account of the Sole Risk Parties.

            Section 6.5.       Ownership of Sole Risk Facilities; Financing. (a)
All  materials  and facilities used or constructed for the implementation of a
Sole  Risk  Proposal shall be the property of the Sole Risk Parties.  The Sole
Risk  Parties  shall arrange the financing necessary for the implementation of
the  Sole Risk Proposal and shall be liable for all payments or repayments due
in respect thereof.

           (b)  The JSC will make available to the Sole Risk Parties (or their
Affiliates) the Sole Risk Facilities and/or the additional throughput capacity
arising  therefrom.   The Sole Risk Parties (or their Affiliates) shall ensure
that  the  Throughput  Capacity in the affected Segment or part thereof (other
than  that  created by other Sole Risk Facilities) and all relevant unutilized
facilities shall be used before any Sole Risk Facilities or throughput
capacity created by the Sole Risk Facilities are used.

             Section 6.6.       Data and Information. All data and information
obtained  or  arising  in respect of a Sole Risk Proposal or amended Sole Risk
proposal  shall be made available to the JSC,  provided that the JSC shall not
be the owner thereof.

           Section 6.7.       Tariffs.  (a)  The tariffs charged by the JSC on
each barrel using, or deemed to use, the Sole Risk Facilities shall be
calculated so as to be sufficient to cover:

<PAGE>
      (i)  all fixed Operating and Maintenance Costs other than those included
in (ii) below attributed by the JSC to the Sole Risk Capacity;

     (ii)  the proportion of the total overhead and fixed Operating and
Maintenance Costs of the JSC other than those in (i) above, Operator
incentives  and  applicable  Colombian Taxes (other than taxes attributable to
the profits earned by the JSC in order to pay Distributions and the
Subordinated  Fee) equal to the amount calculated by dividing the total number
of barrels using the Sole Risk Facilities by the aggregate of all barrels
using  (or  deemed  to use) the Oleoducto Central and the Sole Risk Facilities
(the "Sole Risk Throughput Basis"); and

     (iii)  the variable Operating and Maintenance Costs other than those
included in (ii) above which the JSC and the Sole Risk Parties agree, or,
failing  agreement,  the JSC determines, to charge either (A) on the Sole Risk
Throughput Basis, or (B) on the basis of the cost increment to the JSC
associated with the Sole Risk Facilities and the additional throughput
capacity created by them.

The tariff shall include a fixed component based on barrels nominated for
shipment  arising from the items referred to in clause (i) above and that part
of clause (ii) above that may be agreed upon by the JSC and the Sole Risk
Parties  which shall be payable by the Sole Risk Parties regardless of volumes
of Petroleum actually shipped.

           (b)  The JSC shall be entitled to review (on one occasion only) the
basis of charging tariffs under clause (iii) of paragraph (a) above five years
after the coming into service of the Sole Risk Facilities and may either
confirm such basis or change it to the other basis referred to therein.

          Section 6.8.     Decommissioning; Indemnity. (a) The Sole Risk Parties
may  on  reasonable  notice  in writing require the JSC to decommission and/or
remove any Sole Risk Facilities owned by the Sole Risk Parties.  The JSC shall
consent to the request for the decommissioning and/or removal of the Sole Risk
Facilities (or part thereof) provided that the JSC, acting through the
Operator, certifies that such decommissioning and/or removal will not
prejudice the safety or integrity of the Oleoducto Central.

             (b)   Any cost incurred in such decommissioning and removal shall
be for the account of and be borne by the Sole Risk Parties, and the Sole Risk
Parties, pro rata to their interest in the Sole Risk Facilities, shall jointly

                    PRE-COMPLETION DATE RIGHT TO PURCHASE

             Section 9.1.       Reorganization Party.  Prior to the Completion
Date, unless the Parties otherwise agree, a Shareholder (and any related
guarantor  under  a Performance Guarantee Agreement) shall be a Reorganization
Party in the event that any of the following events occurs:


<PAGE>
           (a)     an order is made by a court of competent jurisdiction, or a
resolution  is  passed,  for the dissolution or judicial administration of the
Shareholder  or any related guarantor under a Performance Guarantee Agreement;
or

          (b)     a manager, receiver, administrator, trustee or other similar
officer  is  appointed  in  respect of any assets which include either (i) the
Shares  held  by  the  Shareholder or (ii) shares of the Shareholder or of any
related guarantor under its Performance Guarantee Agreement; or

            (c)such Shareholder or any related guarantor of such Shareholder's
obligations  under  its  Performance Guarantee Agreement convenes a meeting of
its  creditors  generally and makes or proposes any arrangement or composition
with, or any assignment for the benefit of, its creditors generally.

            Section 9.2.       Right of Unrelated Shareholder to Purchase  (a)
If  a  Reorganization Party does not cease to be a Reorganization Party within
180  days after becoming a Reorganization Party, the other Shareholders shall,
unless  Ecopetrol is the Reorganization Party, subject to applicable law, have
the right, but not the obligation, to purchase or procure the purchase of all,
but  not  less than all, of the Shares held by the Reorganization Party or its
related Shareholder.  If Ecopetrol is the Reorganization Party the other
Parties  shall  only  have the right, but not the obligation, to purchase all,
but  not  less  than all, of Ecopetrol's Shares if prior thereto Ecopetrol has
complied with all laws applicable to it with respect to the sale by it of such
Shares.

              (b)     Such purchase right shall be exercised by one or more of
the other Shareholders by delivering a notice to the Reorganization
Shareholder  at  any  time  within a period of 60 days after the expiry of the
180-day period referred to in paragraph (a) above.  The Shareholder or
Shareholders  exercising  such right shall purchase such Shares pro rata based
on  the  proportion  that  their respective Shareholding Interests bear to the
Shareholding  Interest  of  the Reorganization Party unless the Reorganization
Party is otherwise advised by all of such other Shareholders.  The price
payable  by  such  Shareholder or Shareholders to the Reorganization Party (or
its  related Shareholder) shall be the Fair Market Value of the Reorganization
Party's (or its related Shareholder's) Shares.  The sale of the Reorganization
Party's Shares shall be completed within 14 days of the date on which the Fair
Market  Value is determined or, if later, when governmental and other required
third party approvals or consents are obtained.

              Section 9.3.       Indemnification by Reorganization Party.  The
Reorganization Party shall indemnify and hold harmless the other
non-defaulting Parties against any loss, liability, damage or claim (or action
in  respect  thereof) (including, but not limited to, legal fees and expenses)
suffered or incurred:

          (a)     as a result of the occurrence of the events listed in
Section 9.1; or

          (b)     in connection with the enforcement, preservation or
protection of any rights against the Reorganization Party under this
Agreement;

<PAGE>
provided, however, that in no event shall the Reorganization Party be
obligated  to  indemnify  the other Parties for loss of anticipated profits or
other consequential damages.

          Section 9.4.       Inapplicability After Completion Date.  This

                                 ARTICLE TEN

                             PERMITTED TRANSFERS

          Section 10.1.       Permitted Transfers. Except to the extent
otherwise provided in this Article Ten, no Shareholder shall transfer any
Shares to any other Person without the unanimous written approval of each
other Shareholder.  For purposes of this Article Ten, a transfer of all or any
Voting Shares of a Shareholder or of any Parent Holding Company of a
Shareholder  shall be subject to the same restrictions on transfer as apply to
the  transfer of Shares hereunder.  "Parent Holding Company" means, with respect
to any Shareholder, any Person that, directly or indirectly through any
Subsidiary, owns, as its sole material asset, Voting Shares that enable it, in
the  absence  of  contingencies, to elect a majority of the board of directors
(or persons performing similar functions) of such Shareholder.

          Section 10.2.       Transfer in Connection with Assignment of
Undivided  Interest in Association Contracts  .  Notwithstanding Section 10.1,
subsequent  to  the date on which the aggregate amount of Senior Debt expected
to  be  provided  by  the Senior Lender Group for whose benefit the Collateral
related  to  such Shareholder's Initial Shipper Group has been assigned by the
JSC  and  Equity  Contributions  have been funded, any Shareholder (other than
Ecopetrol)  which is a member of an Initial Shipper Group shall have the right
to transfer all or any portion of its Shares if such transfer is made in
connection  with the simultaneous assignment of all or a Corresponding Portion
of  the  undivided interest held by such Shareholder or its affiliated Initial
Shipper  in  the Association Contracts to a party that agrees in writing to be
bound by all of the provisions of this Agreement and of the Project Agreements
to which the transferor Shareholder or its Affiliate is a party (in which case
such transferee shall be considered to be a "Shareholder" under this Agreement).
  For  purposes  of  this Section 10.2," Corresponding Portion" of the undivided
interest in the Association Contracts means the portion, expressed as a
percentage,  equal  to  the  number of Shares being transferred divided by the
aggregate  number of Shares held by such Shareholder immediately prior to such
transfer.  Nothing contained herein shall constitute a derogation or waiver of
any rights of the parties to the JOA or the Association Contracts.

             Section 10.3.       Transfers to Persons in Petroleum and Natural
Gas Industry.
  (a)   Notwithstanding Section 10.1, and subject to paragraph (b) below, any
Shareholder (subject, in the case of transfers by IPL Enterprises or TCPL
International, to Section 10.8 and receipt of the written consent of
Ecopetrol), shall have the right to transfer Shares if the transfer is made:

<PAGE>
     (i)  prior to the date on which the aggregate amount of Senior Debt to be
provided  by  the Senior Lender Group for whose benefit the Collateral related
to  such Shareholder's Initial Shipper Group has been assigned by the JSC, and
Equity Contributions have been funded, to a Person (other than an individual)

        (A)  whose primary purpose or business is the exploration for, and the
development  and operation of, Petroleum or natural gas fields and the lifting
and sale of Petroleum or natural gas or the development and operation of
pipelines for the transportation of Petroleum or natural gas,

      (B)  that agrees in writing to be bound by all of the provisions of this
Agreement and the Subscription Agreement with respect to such Shares and

       (C)  who has, or causes a Performance Guarantee Agreement to be entered
into  by  a Person that has, a minimum net tangible book value of $500 million
(or the equivalent thereof) and a long-term senior unsecured debt rating
assigned  to  it  of not less than (x) "A" by Standard & Poor's Corporation or
its equivalent by another Internationally Recognized Statistical Rating Agency
or  (y)  "BBB"  by  Standard & Poor's Corporation or its equivalent by another
Internationally  Recognized  Statistical  Rating  Agency if 85% or more of the
aggregate  amount  of Senior Debt expected to be provided by the Senior Lender
Group  for  whose benefit the Collateral related to such Shareholder's Initial
Shipper Group has been assigned by the JSC and of Equity Contributions
(including at least 85% of the amount of the Senior Debt) has been funded; or

     (ii)  subsequent to the date on which the aggregate amount of Senior Debt
expected to be provided by the Senior Lender Group for whose benefit the
Collateral related to such Shareholder's Initial Shipper Group has been
assigned  by  the  JSC  and Equity Contributions have been funded, to a Person
(other than an individual)

       (A) that agrees in writing to be bound by all of the provisions of this
Agreement and the Subscription Agreement with respect to such Shares, and

       (B) has, or causes a Performance Guarantee Agreement to be entered into
by  a Person that has, a long-term senior unsecured debt rating assigned to it
not  lower  than  "BBB-"  by Standard & Poor's Corporation or its equivalent by
another Internationally Recognized Statistical Rating Agency.

            (b)  A Shareholder making a transfer under Section 10.3 shall sell
Shares  representing a Shareholding Interest of not less than 5% in any single
transaction  to  any  single transferee, provided that (i) if such Shareholder
then  has  a  Shareholding  Interest of less than 5% immediately prior to such
sale,  such Shareholder shall be permitted hereunder to sell all, and not less
than  all,  of  its Shares and (ii) the transferring Shareholder shall receive
the written approval of a majority of the Shareholders (other than such
Shareholder), which approval shall be granted unless in the reasonable view of
such  Shareholders  the criteria set forth in Section 10.3(a)(i) and (ii) have
not been met.

<PAGE>
           (c)  A Shareholder proposing to transfer Shares pursuant to Section
10.3(a)(i)  or  (ii) shall deliver to each other Shareholder written notice of
the  proposed  transfer, including the identity of the proposed transferee and
the  date  upon which such transfer is proposed to be made, which shall be not
earlier than 30 days from the date of such notice.  Upon receipt of such
notice  the  Shareholders  shall  consult in good faith in order to approve or
disapprove such transfer pursuant to paragraph (b).

          Section 10.4.       Transfers to Affiliates.  Notwithstanding
Section  10.1,  any Shareholder shall have the right to transfer Shares if the
proposed transferee is an Affiliate of such Shareholder, ovided that any
guarantee  of  such Shareholder's obligations under its Subscription Agreement
shall remain in effect and, only if all of such Shares are transferred to such
transferee, such transferee agrees in writing to be bound by all provisions of
this  Agreement and to enter into a Subscription Agreement (in which case such
transferee shall be considered to be the "Shareholder" under this Agreement). If
the transferring Shareholder's obligations hereunder and under its
Subscription  Agreement  are  guaranteed,  such guarantee shall be extended to
cover such transferee's obligations under its Subscription Agreement,
otherwise  the  transferring  Shareholder  shall guarantee unconditionally the
performance of such transferee's obligations under this Agreement, the
Subscription Agreement, the Voting Trust Agreement and the Dividend Trust
Agreement.

          Section 10.5.       Transfers to Other Shareholders. Notwithstanding
Section 10.1, any Shareholder (subject, in the case of transfers by IPL
Enterprises  or TCPL International, to Section 10.8 and receipt of the written
consent  of  Ecopetrol)  may transfer Shares to one or more other Shareholders
subject to applicable law and subject to the following conditions:

            (a)     If a Shareholder proposes to transfer, assign or otherwise
dispose  of  any  portion of its Shares to another Shareholder or an Affiliate
thereof which is not an Affiliate of such Shareholder, and has received a bona
fide  offer  that  it  is willing to accept, then the transferring Shareholder
shall  cause  the  Shareholder  transferee or its Affiliate to agree (and each
Shareholder  hereby  agrees)  to  give notice to the other Shareholders of the
proposed transfer and of the terms and conditions of such offer, including the
consideration offered and the date upon which the sale is proposed to be made,
which  shall not be earlier than 75 days nor later than 120 days from the date
of  such  notice,  and  offering such Shares to such other Shareholders on the
terms  and  conditions  of the offer of such proposed Shareholder transferee.
Thereafter,  the other Shareholders, or any of them, including the Shareholder
transferee  (together,  the" Purchasing Shareholders"), shall have the right, by
notice  to  the transferring Shareholder and the Shareholder transferee within
90  days  after  receipt  of such notice of the proposed transfer, to elect to
acquire  all  (but not a portion) of such Shares for the consideration offered
(or, if the Purchasing Shareholders so elect, the cash equivalent thereof) and
in  accordance  with  the other terms and conditions of such offer.  Shares so
offered shall be purchased by the Purchasing Shareholders pro rata in the
proportion that their respective Shareholding Interests bear to the total
number of Shares being offered unless the transferring Shareholder is
otherwise advised by all of the Purchasing Shareholders prior to the effective
date of the transfer of the Shares, in which

<PAGE>
case the Shares shall be acquired by the Purchasing Shareholders as so advised
by them, and shall be transferred and delivered by the transferring
Shareholder directly to such Purchasing Shareholders pursuant to the terms and
conditions of the original offer.  If no Shareholder other than the
Shareholder transferee elects to acquire the Shares, the transferring
Shareholder and the Shareholder transferee may proceed to complete the
transfer between them in accordance with the original offer not later than 120
days  after  the notice of the proposed sale given to the other Shareholders.
If  the transfer is not completed by that date, the provisions of this Section
10.5  shall  again  apply and no sale or transfer may be made in reliance upon
this Section 10.5 without again complying with its provisions.
Notwithstanding  the  foregoing,  no  Shareholder may acquire any Shares under
this Section 10.5 unless it has caused its Subscription Agreement and any
Performance Guarantee Agreement of its obligations thereunder to be amended to
increase the dollar amount limitations thereof by an amount in the same
proportion  to the previous amount as the aggregate number of Shares purchased
pursuant to this Section 10.5 bears to the aggregate number of Shares
previously held by such Shareholder.  For purposes of this Section 10.5,
unless  the Shareholders otherwise agree, the price payable by any Shareholder
shall be payable in dollars.

          (b)     If any governmental approval or authorization is required to
permit  the  purchase  of Shares by any Purchasing Shareholder under paragraph
(a),  the  120-day period shall be extended for such period as is necessary to
secure such approval, provided that the transferring and  Purchasing
Shareholders diligently pursue such approvals.

          Section 10.6.      Public Offering of Shares.  (a) Prior to the
funding  of  the  aggregate amount of Senior Debt and Equity Contributions, no
Shareholder  shall  offer  any  of its Shares by means of a public offering or
otherwise  obligate  the  JSC to (nor shall the JSC take any action that would
cause it) to become a public "reporting issuer" within the meaning of any
securities  law  without  the  prior approval of Shareholders holding at least
90.41%  of  the outstanding Shares, which approval may, in the sole discretion
of  such Shareholders, be conditioned upon, among other matters, amendments to
this Agreement and the By-Laws reasonably satisfactory to each of such
Shareholders.

          (b)     Notwithstanding clause (a) above, if requested by the
Government of Colombia to allow the public offering of Shares held by
Ecopetrol,  each  Shareholder agrees to grant its approval under paragraph (a)
of  this  Section  10.6  and to use its reasonable efforts to cause the JSC to
take,  and  the  JSC agrees to take, all reasonable action necessary to effect
the public offering of such Shares, provided that (i) Ecopetrol shall
cooperate  with  the JSC in order to make amendments to this Agreement and the
By-Laws reasonably satisfactory to each of the Shareholders and (ii)
notwithstanding  anything  to the contrary herein, Ecopetrol shall continue to
have  all  the  duties, obligations and liabilities of a Shareholder hereunder
and  under  its  Subscription Agreement in respect of such Shares and that for
purposes  of  calculating its Proportionate Share or its Shareholding Interest
for the determination of its duties, obligations and liabilities hereunder and
under  its  Subscription  Agreement  and Advance Tariff Agreement, such Shares
shall be deemed to be held by Ecopetrol.

<PAGE>
           Section 10.7.       Transfers by Parent Holding Companies.  (a)  If
any  Parent  Holding  Company of a Shareholder shall attempt to circumvent the
restrictions on transfer set forth in this Article Ten through any transfer of
Shares  held  by  such  Shareholder or otherwise, each other Shareholder shall
have the right, at its option, to purchase the Shares of each such
Shareholder,  pro rata to its Shareholding Interest, for a cash purchase price
equal  to  the  Fair Market Value of such Shares, payable in dollars within 30
days of written notice of such election.

          (b)  Each Shareholder shall give written notice to the Board of
Directors  of  any transaction that involves a change of control of any parent
company of the Shareholder, including the ultimate parent company of the
Shareholder,  substantially  contemporaneously with any public announcement of
any such transaction.

accordance  with the terms of, and subject to the conditions contained in, the
Share Transfer Agreement.  Section 10.1 shall not apply to any transfers
referred to in this Section.

Notwithstanding Section 10.1, TCPL International shall have the right to
transfer  all,  but not less than all, of its Shares to TCPL Bermuda, provided
that TCPL Bermuda signs a counterpart of this Agreement, a counterpart of TCPL
International's Subscription Agreement and a counterpart of the Political
Events Agreement whereupon TCPL Bermuda shall assume all rights and
obligations  of  TCPL  International as a Shareholder hereunder and under such
Subscription  Agreement  and  Political  Events Agreement.  Upon execution and
delivery of such counterpart by TCPL Bermuda,

       (a)   TCPL International shall be released of all obligations hereunder
other  than  its  obligations under Section 11.1 and Section 11.2 and shall be
released  from  all obligations under its Subscription Agreement in accordance
with the terms thereof; and

     (b)  TCPL Bermuda shall thereafter be considered a Shareholder and a
Party for all purposes hereunder.

shall hold such Shares subject to the provisions contained in the Voting Trust
Agreement and the Dividend Trust Agreement, in each case as if it were a
member of the Initial Shipper Group from which it acquired such Shares,
respectively,  and  each  Shareholder shall, as a condition to any transfer of
its  Shares,  require that such transferee agree in writing for the benefit of
the other Shareholders party thereto to comply with the terms of such
agreements as if it were a party thereto.

to  any  environmental or other emergency or as permitted by Section 11.1(d).
As to any disclosure pursuant to Section 11.1(a) or (b), only such
Confidential  Information as such third party shall have a legitimate business
need to know shall be disclosed and, in the case of disclosure to a third
party permitted by Section 11.1(a), the Party disclosing such information
shall  cause  such  party to protect the Confidential Information from further
disclosure  to the same extent as the Parties are obligated under this Section
11.1 and, in the case of disclosure to a third party permitted by Section
11.1(b)  or  11.1(c),  the  Party disclosing such information shall cause such
third party to first agree in writing to so protect the Confidential
Information.

             Section 11.2.       Return of Confidential Information.  Upon any
Party demanding the return of Confidential Information relating to it by
notice in writing to another Party, the other Party shall, and shall cause its
representatives to,

              (a)     return all documents containing Confidential Information
that have been provided by the Shareholder demanding the return of
Confidential Information (or on its behalf); and

              (b)     destroy any copies of such documents and any document or
other  record  reproducing,  containing  or made from or with reference to the
Confidential Information,

except, in each case, for any submissions to or filings with judicial,
administrative, legislative or regulatory authorities.  Such return or
destruction  shall take place as soon as practicable after the receipt of such
notice, provided, however, that this Section shall not apply to the JSC to the
extent it reasonably believes it has such Confidential Information for
purposes of the Oleoducto Central.

<PAGE>
           Section   Consultation as to Announcements.  No public announcement
or  press  release concerning the business of the JSC, including the Oleoducto
Central, shall be made by any Party or the JSC without prior consultation with
the  JSC and each of the other Parties.  This provision shall not prohibit any
public announcement or press release required to be made by the laws,
regulations or policies of any federal, provincial or state governmental
agency or similar agency or any stock exchange or similar regulatory authority
or  if  required by the reasonable good faith judgment of the disclosing Party
as a response to any environmental or other emergency that may have a
significant  adverse  effect upon the JSC, provided that the Party making such
announcement  shall, to the extent practicable, consult with the other Parties
concerning the timing and content of such announcement before such
announcement is made and shall give a copy thereof to each of the other
Shareholders at the same time, or as soon as reasonably practicable after, the
making of such announcement.


                                ARTICLE TWELVE

                                     TERM

              Section 12.1.       Term.  This Agreement shall become effective
when  executed  and delivered by all the Parties and, subject to Section 12.2,
shall continue to be in effect so long as the JSC continues to be in existence
in accordance with the By-Laws.

           Section 12.2.       Termination Events.  Subject to Section 12.3(a)
below, this Agreement shall terminate

          (a)  at such time as no Shareholder which is also an Initial Shipper
or an Affiliate thereof has a Shareholding Interest greater than 5%;

          (b)  at such time as the Shareholders may otherwise unanimously
agree; or

          (c)  at 5:00 p.m., local time, Santafe de Bogota, Colombia, on March
31,  1995, if (i) the JSC shall have received from any Shareholder on or prior
to  March  15,  1995  a certified copy of a resolution adopted by the board of
directors or equivalent decision making body, or an authorized committee
thereof, of The British Petroleum Company p.l.c., Ecopetrol, TOTAL S.A.,
Triton  Energy  Corporation, IPL Energy or TransCanada PipeLines to the effect
that such board, body or committee has resolved to, or to cause its subsidiary
Shareholder  to,  withdraw from the Oleoducto Central project and to terminate
this Agreement, and has not received prior to 5:00 p.m. local time, Santafe de
Bogota,  Colombia  on March 31, 1995 either (A) a notice of withdrawal of such
resolution  or  (B) a Notice of Continuance from a non-Withdrawing Shareholder
referred to in Section 12.3(a).

          As soon as practicable after adopting a resolution pursuant to
paragraph (c), the ultimate parent company having resolved to cause the
termination of this Agreement or its affiliated Party shall deliver to the JSC
with  copies to all other Parties written notice of such resolution.  Promptly
after receipt of such notice, the Parties shall meet in good faith and
endeavor to agree mutually acceptable terms on which to continue with the
Oleoducto

<PAGE>
Central.  A Shareholder properly delivering such notice is hereinafter
referred to as a "Withdrawing Shareholder."

          Section 12.3.       Termination.  (a)  The non-Withdrawing
Shareholders shall be entitled to elect to continue with the Oleoducto
Central.   The non-Withdrawing Shareholder or Shareholders shall evidence this
decision  by  delivering to the JSC, prior to 5:00 p.m. local time, Santafe de
Bogota,  Colombia,  on March 31, 1995, a notice to this effect (the "Notice of
Continuance"), with a copy to the Withdrawing Shareholder.  Any
non-Withdrawing Shareholder which does not sign the Notice of Continuance
shall  be  deemed  to  be a Withdrawing Shareholder.  In the event a Notice of
Continuance is delivered, either (i) or (ii) below will apply.

     (i)(A)  If the Withdrawing Shareholder is an Initial Shipper, the
non-Withdrawing Shareholders, pro rata to their remaining Shareholding
Interests  in  the  JSC, shall purchase, and the Withdrawing Shareholder shall
sell, all the Withdrawing Shareholder's equity in the JSC.  Such purchase
shall  be  made at a price equal to the lesser of (x) 75% of the book value of
the  Withdrawing Shareholder's equity in the JSC, and (y) such book value less
$2,000,000  provided that for this purpose book value shall never be less than
zero.    Such  book value shall be determined on the basis of the books of the
JSC at the month end prior to the delivery of the Notice of Continuance.

      (B)  If Ecopetrol is a Withdrawing Shareholder and its equity in the JSC
is  sold  in  whole  or in part to a third party because of the requirement of
Colombian  law  relating to the transfer of shares held by it, Ecopetrol shall
remain liable under its Subscription Agreement in proportion to the portion of
Ecopetrol's Shareholding Interest so sold to a third party.

     (ii)(A)  If the Withdrawing Shareholders are either IPL Enterprises
and/or TCPL International, the non-Withdrawing Shareholders, pro rata to their
remaining Shareholding Interests in the JSC, shall purchase, and the
Withdrawing Shareholder or Shareholders shall sell, all of its or their equity
in the JSC.

     (B)  If the reason for the withdrawal of one or both of the Canadian
Group  Withdrawing  Shareholders is that, after negotiating in good faith, the
JSC  and the Operator were unable to reach agreement on terms of the Oleoducto
Central Operations Agreement and the Transportation Agreements containing
commercially  reasonable  terms  consistent with the Operating Principles, the
Tariff Principles and internationally accepted standards for similar
agreements,  then  the  price to be paid for the equity in the JSC held by the
Withdrawing Shareholder or Shareholders shall be equal to its share of
Recoverable  Costs,  provided,  however, that if the reason such agreement was
not  reached was primarily due to the failure of the Operator and the Canadian
Group  to negotiate in good faith, then the price to be paid for the equity in
the  JSC held by the Withdrawing Shareholder or Shareholders shall be equal to
its or their share of the Recoverable Costs, less $3,000,000.

     (C)  If the withdrawal of one or both of Canadian Group Withdrawing
Shareholders  occurs  primarily for any other reason, the price to be paid for
the

<PAGE>
equity in the JSC held by the Withdrawing Shareholder or Shareholders shall be
five pesos.

       (D)  Should the Shareholders fail to agree on either the reason for the
withdrawal  or  whether the Operator and Canadian Group failed to negotiate in
good faith, those issues shall be determined as follows and the purchase price
paid accordingly.  If within the 15 Business Day  period specified for payment
in sub-section (iv) below the Shareholders have not been able to agree whether
the  proviso  to paragraph (B) above applies, they or any of them shall notify
the  President  of the American Petroleum Institute of the impasse.  Within 20
Business  Days  thereafter he shall appoint an umpire to decide whether or not
the proviso applies.  The umpire shall be an individual of established
reputation  with knowledge of the oil production and pipeline industries.  The
umpire  in  making  his  decision shall consult with the principal independent
advisors  to the Shareholders.  The umpire shall render his decision within 60
Business  Days  and  such  decision shall be solely whether or not the proviso
applies.  The outcome of such decision shall be communicated by him in writing
to each of the Shareholders.  Payment for the Withdrawing Shareholder's equity
interest in the JSC shall be made in accordance with such decision within five
Business  Days  thereafter.   Any such decision shall be conclusive as to, and
binding  on, all Parties.  The Withdrawing Shareholder or Shareholders and the
remaining  Shareholders  as  a group shall each be responsible for one half of
the fees and expenses of the umpire, and, jointly and severally, shall
indemnify and hold harmless such individual against all expenses, claims,
losses  and liabilities (including legal fees and expenses and any expenses of
such  independent  advisors)  however incurred arising out of or in connection
with the performance of the services described in this paragraph.

         (iii)  If the Notice of Continuance is not delivered, Section 12.3(b)
shall  apply,  and in addition, when the JSC has been dissolved and liquidated
and  its  assets fully distributed, if the Canadian Group has not received out
of  that  distribution its Recoverable Costs, then the Withdrawing Shareholder
or  Shareholders,  pro  rata  to their remaining Shareholding Interests in the
JSC,  shall pay the difference to the Canadian Group in dollars promptly after
such  distribution.  Each Shareholder agrees that if it may be liable for such
a payment, no distribution shall be made to it in connection with the
dissolution and liquidation of the JSC under Section 12.3(b) unless such
Shareholder has made the payment (if any) required under this sub-section, and
if  such  payment  is  not made, any distribution to which such Shareholder is
entitled  under  this paragraph shall be paid over to the Canadian Group.  The
payment over to the Canadian Group of the Withdrawing Shareholder's
distribution shall only extinguish the liability of the Withdrawing
Shareholder under this paragraph if it is equal to or greater than such
liability.    "Recoverable  Costs"  shall mean an amount equal to (A) the Cash
Paid-In  Equity of the Canadian Group to the JSC without interest, and (B) the
reasonable  unreimbursed costs incurred by the Canadian Group in mobilizing to
become Operator and in de-mobilizing to disband its role as Operator as a
result of the dissolution and liquidation of the JSC, unless the Canadian
Group continues as operator of the Oleoducto Central after the dissolution and
liquidation of the JSC.

<PAGE>
      (iv)  Any purchase and sale pursuant to this Section 12.3(a) shall occur
within  15 Business Days following such delivery.  The purchase price shall be
payable  outside Colombia in dollars on the basis  of the peso/dollar exchange
rate  quoted by the Reference Bank in New York at the close of business on the
Business Day preceding the date of transfer.  Simultaneously with the purchase
and  sale the non-Withdrawing Shareholders shall, unless they otherwise agree,
assume,  according  to  their  pro rata share of the purchase, the Withdrawing
Shareholder's  rights and obligations under its Subscription Agreement arising
after  March  31,  1995,  any related Performance Guarantee Agreement shall be
terminated,  and  any non-Withdrawing Shareholder whose Subscription Agreement
is  the  subject  of a Performance Guarantee Agreement shall procure that such
Performance Guarantee Agreement be expanded to cover the Subscription
Agreement obligations assumed by it.

         (v)  Upon any transfer of equity referred to in this Section 12.3(a),
this  Agreement shall terminate as to the Withdrawing Shareholder, except that
its obligations under Sections 11.1 and 11.2 shall survive and the Withdrawing
Shareholder  shall remain liable for any liabilities incurred by it under this
Agreement  prior to 5:00 p.m. local time, Santafe de Bogota, Colombia on March
31,  1995.    Thereafter  a Withdrawing Shareholder shall have no liability or
responsibility for  procuring, or as the result of any failure to procure, any
Senior Debt.

      (vi)  Each Initial Shipper hereby covenants that, if it is a Withdrawing
Shareholder  and  the non-Withdrawing Shareholders elect to deliver the Notice
of  Continuance,  it  shall ship or cause to be shipped all its Petroleum from
the  Fields  by means of the Oleoducto Central, provided that it shall have no
obligation to pay a tariff for such shipments exceeding the higher of the
Third Party Tariff and the Initial Shipper Tariff in effect from time to time.

     (vii)  Any shares of the JSC transferred pursuant to this Section 12.3(a)
shall continue to be subject to the Dividend Trust Agreement and, if
transferred to a Shareholder other than Ecopetrol, the Voting Trust Agreement.

     (viii)  The Parties agree that there will be no calls for Equity
Contributions  made for payment on any day in the period from March 15 through
March 31, 1995 (including such dates).

              (b)  In the event of termination of this Agreement in accordance
with paragraph (c) of Section 12.2, (i) the JSC shall be dissolved in
accordance with the By-Laws; (ii) the JSC shall promptly cancel all
commitments  it  has  made (taking all reasonable steps to minimize any costs,
liabilities  and  penalties  associated with such action); (iii) the JSC shall
dispose of its assets on the best commercial terms reasonably achievable,
provided  that each Shareholder shall have the right to acquire assets sold or
otherwise  transferred  by  it to the JSC prior to any such disposal, provided
further  that  any sale of assets to a Shareholder from which such assets were
purchased shall be at a price not less

<PAGE>
than the sale price to the JSC; (iv) the JSC shall be liquidated in accordance
with the By-Laws and applicable law; and (v) any costs and penalties
associated  with  the actions outlined in (i) through (iv) above which the JSC
is unable to satisfy from its own assets shall be borne by the Shareholders in
proportion to their respective Shareholding Interests.

              (c)  In the event of termination of this Agreement in accordance
with paragraph (a) or (b) of Section 12.2 or Section 12.4, this Agreement
shall  thereafter have no effect, and no Party shall have any liability to the
other Parties in respect hereof, except that (a) the obligations of the
Parties  in  Sections  11.1 and 11.2 shall survive for a period of three years
from  the  date of termination with respect to any Party and/or its Affiliates
which sells or otherwise disposes of all or any part of its Shareholding
Interest,  (b)  the rights of the Shareholders under Section 8.2 shall survive
for  a period of six years from the date of termination and (c) nothing herein
contained shall relieve any Party from liability for any breach of any
representation, warranty or agreement hereunder occurring prior to such
termination.

              (d)  In the event of termination of this Agreement in accordance
with  paragraph  (c)  of Section 12.2, this Agreement shall thereafter have no
effect except that this Section 12.3 shall survive.

          (e)  In the event of termination of this Agreement pursuant to
Section 12.2 or Section 12.4, no Party shall under any circumstances be liable
to  the  other  Parties  for loss of anticipated profits from the transactions
contemplated  by this Agreement or for other consequential damages (including,
without limitation, loss or deferment of production from the Fields or
throughput  rights in the Oleoducto Central) arising out of the termination of
this Agreement.

          Section 12.4.       Political Events Agreement.  This Agreement
shall  terminate  as  to  any Shareholder as specified in the Political Events
Agreement.

           Section 12.5.       RMOU.  The Parties acknowledge that the parties
to the RMOU have, pursuant to a letter agreement of even date herewith,
terminated the RMOU in accordance with the terms thereof.


                               ARTICLE THIRTEEN

            NEGOTIATIONS; ARBITRATION; SUBMISSION TO JURISDICTION

          Section 13.1.       Negotiations; Arbitration.  (a)  In the event of
any dispute, controversy or claim arising out of or relating to this
Agreement, or the performance, breach, termination, or invalidity hereof, such
dispute, controversy or claim, shall be the subject of an attempt at an
amicable  solution, for which purpose any Party shall give notice to the other
Parties, giving a concise description of the matter in question and the
position  of  such  Party in respect thereof and proposing a meeting among the
chief executive officers, executive managing directors or their designees (the
"Senior  Officers")  of the ultimate parent companies of the Shareholders in The
City  of  New York (or such other place as they may agree) with the purpose of
resolving the dispute, controversy or claim.

<PAGE>
              (b)     In the event such a meeting is called, the meeting shall
take place within 10 days of its being requested.  Unless the Parties
otherwise agree, if such meeting does not take place within such 10 days or if
within  10  days after such meeting the Senior Officers have not resolved such
matter, then the matter shall be settled by arbitration in accordance with the
UNCITRAL Arbitration Rules in effect on the date hereof.  The arbitration
shall be the sole and exclusive forum for resolution of the dispute,
controversy or claim, and the award shall be final and binding.  Judgment
thereon may be entered by any court having jurisdiction.  The number of
arbitrators shall be three, each of whom shall be disinterested in the
dispute,  controversy  or  claim and shall have no connection with any Party.
Should  the  services  of an appointing authority be necessary, the appointing
authority  shall  be  the American Arbitration Association.  In the event that
more  than  two Parties are involved in the dispute, controversy or claim, all
such Parties shall have 30 days to agree among themselves as to the
appointment of the three arbitrators.  If, after such 30-day period, the
Parties  have  not  agreed on such appointment, the appointing authority shall
select  all  three  arbitrators.  The Parties and the appointing authority may
appoint  from  among the nationals of any country, whether or not a Party is a
national  of  that country.  The place of arbitration shall be The City of New
York,  New  York.   The arbitration shall be conducted in the English language
and any foreign-language documents presented at such arbitration shall be
accompanied  by  an  English translation thereof.  The arbitrators shall apply
the laws of the State of New York without regard to the principles of
conflicts of laws.

           (c)     In the event that there is an existing arbitration pursuant
to paragraph (b), and that the same or a similar dispute, controversy or claim
should arise between Parties other than the Parties to the existing
arbitration, the American Arbitration Association shall have the power to
allow  the  other  Parties to be joined in the existing arbitration with their
express  consent,  and  to make a single final award determining all disputes,
controversies or claims among them.

             (d)     Any matter expressed in this Agreement to be a matter for
review,  collaboration,  consultation,  consent,  decision or agreement by the
Parties or any of them shall not, in the event of failure of decision or
agreement,  constitute a dispute or difference to be referred to or settled by
arbitration proceedings.

          (e)     Each of the Parties hereby submits to the exclusive
jurisdiction  of the United States District Court for the Southern District of
New  York (the "Specified Court") in any action, suit or proceeding with respect
to  the  enforcement  of  the arbitration provisions of this Agreement and the
non-exclusive  jurisdiction  of  such court with respect to the enforcement of
any  award  thereunder.  Each Party irrevocably appoints the agent for service
specified  opposite  its  name  in Section 14.1 as its authorized agent in the
Borough  of Manhattan in The City of New York upon which process may be served
in any related proceeding, and agrees that service of process upon such agent,
and  written  notice  of said service to such Party, by the person serving the
same to the address provided in Section 14.1, shall be deemed in every respect
effective service of process upon such Party in any such action, suit or
proceeding.    Each  Party further agrees to take any and all action as may be
necessary  to  maintain such designation and appointment of such agent in full
force and effect for the duration of this Agreement.

Parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the Parties, and there are no warranties, representations or other
agreements  between  the  Parties in connection with the subject matter hereof
except as specifically set forth herein and therein.  No amendment,
supplement,  waiver  or  termination of this Agreement shall be binding unless
executed in writing by the party to be bound thereby.  No waiver of any of the
provisions  of  this Agreement shall be deemed or shall constitute a waiver of
any other provisions (whether or not similar) nor shall such waiver constitute
a continuing waiver unless otherwise expressly provided.

             (a)     it is a corporation duly incorporated and organized under
the laws of its jurisdiction of incorporation;

            (b)     it has the requisite power and authority to enter into and
perform its obligations under this Agreement and this Agreement and the
Project Agreements to which it is a party, when executed and delivered by such
Party, constitute valid and legally binding agreements of such Party;

           (c)     the execution and delivery of, and the performance by it of
its  obligations  under, this Agreement and the Project Agreements to which it
is a party will not result in a breach of or constitute a default under:

                 (i)     any provision of its corporate charter or articles of
incorporation or its by-laws;

               (ii)     any agreement or instrument to which it is a party and
which  is  material  to the performance by it of its obligations hereunder and

shall  be deemed or construed to make any Party a surety or a guarantor of the
JSC or of another Party or liable to meet any obligation of the JSC or of
another Party.

              (b)     The obligations of each Party hereunder shall run to the

obligations of the Shareholders as shareholders of the JSC.

that is unenforceable in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

consents to and waives any objection which it may now or hereafter have to the
laying  of  venue of any proceeding relating to enforcement of the arbitration
provisions  of this Agreement or any award thereunder brought in the Specified
Court and further irrevocably waives, to the fullest extent it may effectively
do  so,  the  defense  of an inconvenient forum to the maintenance of any such
proceeding in the Specified Court.

<PAGE>
             (b)  To the extent that a Party or any of its revenues, assets or
properties shall be entitled, with respect to any proceeding relating to

thereunder at any time brought against such Party or any of its revenues,
assets or properties, to any sovereign or other immunity from suit, from
jurisdiction,  from  attachment  prior  to judgment, from attachment in aid of
execution of judgment, from execution of a judgment or from any other legal or
judicial  process  or remedy, and to the extent that in any jurisdiction there
shall  be  attributed  such  an immunity, such Party irrevocably agrees not to
claim  and irrevocably waives such immunity to the fullest extent permitted by
the laws of such jurisdiction (including, without limitation, the Foreign
Sovereign  Immunities  Act  1976 of the United States), except, in the case of
Ecopetrol,  as provided under Article 684 of the Codigo de Procedimiento Civil

obligations  thereunder,  and not to waive or terminate any rights against any
party thereto except with the approval of the Parties.

the  JSC has the right to conduct a limited audit of each Shareholder in order

audit on any one Shareholder no more than annually.

          Section 14.18.       Limitation on Rights.  No assignee or

                           SHARES AND SHAREHOLDERS


ARTICLE 8.       Registered Form.  The shares of the Company shall be ordinary
shares in nominative (registered) form.

ARTICLE 9.       Share Certificates.  The shares shall be evidenced by
certificates which shall be numbered sequentially in different series for
public entities (Class A) and private shareholders (Class B), shall bear the
signatures of the President and the Secretary of the Company, and shall
indicate:

A.     The name of the Company, its principal domicile, the Notarial Office,
and the number and date of the deed of incorporation.

B.     The number of shares represented by each certificate, their class and
whether their transferability is limited by any preferential rights and the
conditions to exercise such rights.

C.     The full legal name of the person to whom they are issued.

In no event will certificates be issued for a fraction of a share.

By virtue of the shares' fully registered form, the Company shall recognize as
a shareholder of the Company only the person who is registered as such in the
share register book maintained by the Company for that purpose (the Share
Register). No alienation or transfer of shares, liens or restrictions,
attachment or adjudication shall be effective with respect to the Company or
any third party, except by virtue of its registration in the Share Register,
which the Company may not refuse, except by order of a competent authority or
in compliance with any restrictions applicable to the transfer of such shares.

<PAGE>
ARTICLE 10.      Transfer of the Shares.  The shares are negotiable in
accordance with applicable law. For the transfer of the shares to be effective
with respect to the Company and third parties, such transfer must be
registered in the Share Register pursuant to written transfer instructions
from the transferor or under the formality of endorsement of the respective
share certificate. In sales pursuant to court order or other judicial
adjudication, the registration of transfer shall be made upon presentment of
the original or certified copy of the pertinent legal documents containing the
order of whomever is legally responsible therefor.  As established in Decree
_____ of December __, 1994, Ecopetrol will not exercise the preferential
rights contemplated in Article 10 of Decree 130 of 1976.

In connection with any transfer of shares, the prior cancellation of the
certificates issued to the transferor will be required.


ARTICLE 11.       Stolen, Lost and Damaged Share Certificates.  In the event a
share certificate is stolen, the Company shall replace it, issuing a duplicate
to the holder of the shares evidenced thereby as registered in the Share
Register, upon presenting
evidence of such theft satisfactory to the Secretary, presenting a copy of the
notice of loss provided to the relevant legal authorities.  When a Shareholder
requests a duplicate share certificate to replace a lost one, the Shareholder
shall present such bond as may be requested by the President.  A shareholder
who has lost its certificate for any reason shall be responsible to the
Company for any damage or liability suffered by the Company in connection with
the loss of the original share certificate or the issuance of the replacement
therefor. Should the lost share certificate be found, the holder of the shares
previously evidenced thereby shall return the replacement therefor to the
Company, which shall then be destroyed by the Secretary by providing evidence
thereof.  In the event of damage to a share certificate, the Company will
issue a replacement therefor, povided that the shareholder delivers the
original certificates to the Company.

ARTICLE 12.       Issuance and Transfer Costs.  The respective shareholder
shall bear the costs and taxes incident to the transfer of shares and the
issuance of certificates, which expenses shall be born in equal part by the
transferor and transferee, absent agreement otherwise.

ARTICLE 13.  Notices.  Each shareholder must provide its registered address to
the Secretary of the Company.

ARTICLE 14.       Pledges of Shares.  In the case of shares pledged to a third
party, such pledge shall not confer on the third party any rights pertaining
to shareholders, except as otherwise expressly provided by the terms of a
written agreement registered in the Share Register.

ARTICLE 15.       Judicial Proceedings.  The transfer of shares, the ownership
of which is in litigation, shall require authorization from the competent
judicial authority in the forum in which such litigation is pending. In the
case of shares to which a judicial lien has attached, the authorization of the
secured party will also be required. In the event of litigation or judicial
lien regarding the ownership of any shares issued by the Company, the Company
shall abstain from registering any transfer thereof beginning the date on
which it

<PAGE>
 has been notified by the competent authority in which such litigation or
judicial lien is pending.

ARTICLE 16.       Creation of a Certain Class of Shares.  Subject to
compliance with applicable law and these By-Laws, General Meeting of
Shareholders may, at any time, create new classes of shares (including
preference shares, industry shares or other shares with economic rights
preferential to those of the shares). For an issuance of preference shares,
the determination of the respective preferences and the pertinent subscription
resolutions must be approved by a General Meeting of Shareholders upon the
favorable vote of a plural number of shareholders representing not less than
90.41% of the subscribed shares and under the condition that the subscription
resolutions stipulate the preferential right in favor of all shareholders, in
order that the latter may subscribe them proportionately to the number of
shares held by each of them on the date of the offer.

ARTICLE 17.       Rights of the Shareholders.  The shares confer on each
holder thereof the following rights:

A.  To participate in deliberations at General Meetings of Shareholders and to
vote thereat, with one vote per share, with as many votes as the number of
shares held. The restrictions on voting contained in Article 428 of the
Commercial Code do not apply to the shares.

B.  To receive dividends in proportion to its ownership of shares of the
Company in accordance with the end of the accounting period balance sheets,
the By-Laws and applicable law.

and records of the Company at any time, and, in any case, during the 15
business day period preceding the General Meeting of Shareholders whereat the

D.  To receive a share of the corporate assets at the time of liquidation of
the Company pro rata to its holding of shares of the Company and after the
Company's external liabilities have been paid or provided for in accordance
with the decision of the General Meeting of Shareholders.

ARTICLE 18.       Share Register.  The Company shall keep a Share Register
registered at the Chamber of Commerce in Santafe de Bogota, indicating the
names of its shareholders, the provisional certificates, the final
certificates, the number of shares and their series corresponding to each
shareholder, the certificate with its respective registration number and date,
any transfers, pledges, usufructs and other liens or ownership limitations,
attachments or judicial claims, in each case applicable to the shares, as well

Except as required by laws applicable to public entities, representation may

Any power of attorney granted under a Public Deed or other legally accepted

<PAGE>
ARTICLE 22.       Representation of Shareholders. Each shareholder, whether a

shareholders, pro rata to the portion of the par value of their shares.

E. The General Meeting of Shareholders may decide, with the vote of at least
90.41% of the outstanding shares, that there be no distribution of profits by

each General Meeting of Shareholders to fix the time of payment of dividends
and to regulate them, particularly as regards the method and place of payment
to facilitate the timely receipt of dividends by shareholders.

                            AMENDMENTS TO BY-LAWS

ARTICLE 60.       Decisions regarding amendments to the By-Laws shall be
approved in a single debate, which shall take place during a General Meeting
of Shareholders or an Extraordinary Meeting of Shareholders. Any amendments,
once approved by the meeting through the favorable vote of a plurality of
shareholders representing at least 90.41% of the outstanding shares (other
than those related to increases or decreases in authorized capital or the
matters referred to in Article 35 to the extent provided therein), shall be
made in a Public Deed by the President of the Company and shall be registered
with the Chamber of Commerce. Unless otherwise provided, the approval of an
amendment by a meeting of shareholders imposes on the President the obligation
to carry out the legal formalities for its solemnization without requiring any
other authorizations.


                                CHAPTER TWELVE
                  DISSOLUTION AND LIQUIDATION OF THE COMPANY


ARTICLE 61.       Dissolution.  The Company shall be dissolved upon the
grounds determined by the law generally for commercial corporations, upon the
special grounds established by commercial law for stock companies,
extraordinarily, at any time by decision of the General Meeting of
Shareholders, approved and formalized as provided for in these By-Laws for
amendment thereto or, without any action of the Board of Directors or the
General Meeting of Shareholders, April 3, 1995 if the Company shall have
received from any shareholder on or prior to March 15, 1995 a certified copy
of a resolution adopted by the board of directors or equivalent decision
making body, or an authorized committee thereof, of any of Empresa Colombiana
de Petroleos-Ecopetrol, The British Petroleum Company p.l.c., TOTAL S.A.,
Triton Energy Corporation, IPL Energy Inc. or TransCanada PipeLines Limited to
the effect that such board or body or committee has resolved to end such
shareholder's (or, in the case of Ecopetrol, Ecopetrol's) participation in the
Oleoducto Central S.A. and has not received prior to 5:00 p.m., local time,
Santafe de Bogota, Colombia on March 31, 1995 either (A) a notice of
withdrawal of such resolution or (B) a certificate from one or more of the
other shareholders of their intention to continue with the Oleoducto Central
S.A.

ARTICLE 62.       Mandatory Dissolution.  When losses occur which reduce the
net worth of the Company to less than 50% of the subscribed capital, the
Company shall not be dissolved ipso facto, since the General Meeting of
Shareholders may take or order the steps required for the re-establishment of
net worth above 50% of the subscribed capital within six months following the
date of the balance sheet wherein the mentioned losses appear as incurred.
Should these steps not be taken within the indicated period, the General
Meeting of Shareholders shall declare the dissolution of the Company in order
to proceed to its liquidation.

ARTICLE 63.       Notice.  In the event of dissolution of the Company, for
whatever reason, its state of liquidation, once dissolved, shall be
communicated by means of a notice to be published in one or several newspapers
regularly circulating in the corporate domicile

<PAGE>
 of the Company for three or more consecutive business days, and to be posted
in visible places of the offices where the Company has established branches.

ARTICLE 64.       Appointment to Liquidate.  Once the Company has been
dissolved for any reason, the calculation and division of the corporate
capital shall be made in accordance with the legal provisions, by a special
liquidator, who shall be appointed by the General Meeting of Shareholders,
without prejudice to its right to designate liquidators and determine, in such
case, whether they are to act jointly or severally. The General Meeting of
Shareholders shall appoint an alternate for each liquidator. Unless and until
the designation of the liquidator and alternate is made, whoever holds the
office of President of the Company at the time it goes into liquidation, shall
act as such, and his or her alternates shall be the alternates to the
President, first and second, in their order.

ARTICLE 65.       Rules for the Liquidation and Division of the Corporate
Capital.  The liquidation of the Company and the division of its corporate
capital shall be carried out in accordance with the commercial laws and the
applicable provision of the Civil Code, observing the following rules:

A.  The General Meeting of Shareholders shall be summoned and shall meet at
the times, in the manner and upon the terms provided for the ordinary
meetings, and extraordinarily whenever called by the liquidator, the Fiscal
Supervisor, the Superintendency of Companies, or when requested by a plural
number of shareholders representing not less than 9% of the subscribed shares.
At such meetings, it shall perform all functions compatible with the process
of liquidation, and in particular, those of appointing, changing and freely
removing the liquidator or liquidators and their alternates, requesting them
to render accounts, determining the assets which are to be distributed in
kind, and establishing priorities for the realization of assets, manner and
terms of realization, agreeing with the liquidators upon the price of their
services and adopting other determinations which may be in order pursuant to
applicable law or these By-Laws.

B.  The General Meeting of Shareholders may determine which assets are to be
distributed in kind, fix the values of such assets or the manner of
determining them, establish the form of adjudication and authorize the
liquidator to make the required distributions, observing applicable legal
requirements. The General Meeting of Shareholders shall be empowered to
authorize the adjudication of assets pro indiviso by groups of shareholders,
order sales of assets through auctions among the shareholders themselves, or
admit outside bidders, and decide on the use of other forms considered
appropriate.

C.  For the approval of periodic accounts rendered by the liquidator or of the
occasional accounts required from him, as well as to authorize the
adjudication of the assets in kind, authorize payments in kind, grant special
facilities to debtors of the Company and carry out other transactions which
may be necessary or appropriate to facilitate or conclude the liquidation, the
favorable vote of 55% of the outstanding shares shall be required.

D.  For the approval of the final liquidation accounts and of the memorandum
of distribution, the favorable vote of 55% of the outstanding shares shall be
required.

<PAGE>
E.  Upon completion of the Company's liquidation, the liquidators shall
request the appropriate approval from the Superintendency of Corporations.

ARTICLE 66.       Powers of Liquidator.  The liquidator shall have the powers
conferred on him or her by applicable law, which may be extended by the
General Meeting of Shareholders, and his or her actions shall conform at all
times to the applicable law and to the instructions he receives from the
General Meeting of Shareholders.

                                 ARBITRATION

ARTICLE 67.       Arbitration.  Any controversy or dispute among the
shareholders or between the shareholders and the Company in connection with
corporate activities, rights of the shareholders, profit participation,
liquidation of the Company or other matters arising from the existence of the
Company that cannot be resolved directly by the parties, unless applicable law
requires such controversy or dispute to be resolved by judicial proceedings,
they shall be settled by a Court of Arbitration designated by the Board of
Directors of the Chamber of Commerce of Santafe de Bogota by drawing lots
among the arbitrators appearing in the list kept by the Center of Mercantile
Arbitration and Conciliation of said Chamber. The Court thus designated shall
abide by the provisions of the Code of Civil Procedure and the Commercial Code
in accordance with the following rules:  (A) the Court shall consist of three
arbitrators, who must be Colombian citizens and lawyers; (B) the internal
organization of the Court shall be subject to the rules established to such

              Section 3.1.       Exercise of Voting Rights. Subject to Section
3.2, the Voting Trustee shall exercise the Voting Rights attaching to the
Shares of each Shareholder Party in accordance with the direction of such
Shareholder Party in all instances; provided, however, that the Voting
Trustee,  unless  otherwise unanimously instructed by all Shareholder Parties,
shall  exercise  the Voting Rights attaching to all Shares held by it in trust
(encargo fiduciario):

     (a)  So that one nominee of each Nominating Shareholder Party will at all
times be a member of the Board of Directors provided that such Nominating
Shareholder Party continues to be a Shareholder Party at the time of such
election. Five Business Days prior to any election of directors, each
Nominating  Shareholder  Party shall deliver to the Voting Trustee the name of
its nominee (and two alternates thereof):

         (i)  For each election of directors of the JSC, the Voting Trustee on
behalf  of all of the Nominating Shareholder Parties shall submit to the JSC a
single  list  (the "Voting List") for purposes of that election containing (A)
in  the  event of an election of the whole Board of Directors, the name of one
nominee  (and  two  alternates thereof) of each NominatingShareholder Party or
(B) in the event of an election of less than the whole Board of Directors, the
name of one nominee (and two alternates thereof) of each Nominating
Shareholder Party whose nominee does not continue to be a Director of the JSC.

       (ii) In each case of (A) and (B) of clause (i) above, if all Nominating
Shareholder Parties have designated their respective nominees (and
alternates), or one or more Nominating Shareholder Parties have failed to
designate  their  respective  nominees  (and alternates), and as of the fourth
Business  Day  prior to an election, the number of nominees in the Voting List
is less than the number of directors to be elected at such election, the
Voting

<PAGE>
Trustee  shall  notify the Nominating Shareholder Parties who shall consult in
good faith to issue joint instructions to the Voting Trustee for the
designation of mutually agreeable nominees (and alternates) to fill the
vacancies  in the Voting List.  If no agreement is reached prior to the second
Business Day prior to such election, the nominees (and alternates) to fill the
vacancies in the Voting List shall be designated by joint instructions of
Nominating  Shareholder  Parties  holding a majority of the Shares held by all
Shareholder  Parties.  If no instructions have been received by the Trustee by
the end of the last Business Day prior to the election, nominees (and
alternates)  to fill the vacancies on the Voting List shall be designated upon
instructions  of  any  Nominating Shareholder Party and, if more than one, the
Nominating  Shareholder Party holding the larger number of Shares and, in case
of  a  tie,  the  Nominating Shareholder Party that delivered its instructions
first.

      (iii)  The priority order of nominees in the Voting List shall be set in
the declining order of the Shareholding Interest of the Nominating Shareholder
Party designating each nominee, provided that the nominee of a Nominating
Shareholder Party with respect to which a Voting Default is continuing will be
placed  in  order  of  priority after the nominees of all other non-defaulting
Nominating Shareholder Parties and, in the case of a continuing Voting Default
with respect to more than one Nominating Shareholder Parties, their respective
nominees will be placed in the order of priority among them that is the
declining  order  of  the Shareholding Interest of such Nominating Shareholder
Parties provided, further, that a nominee nominated pursuant to clause (ii) of
this  paragraph  (a) shall in all instances occupy the last place in the order
of  priority  in the Voting List and, if more than one, in the declining order
of majority by which they were designated and, in case of a tie, the higher in
priority among them shall be the one designated first.

     (b)  In favor of all Funding Resolutions in accordance with the Financing
Plan and all authorized capital increases pursuant to the Capital Budget and a
Funding Resolution, in each case, approved by the Board of Directors, as
certified thereby;

     (c)  In favor of all Distributions pursuant to Section 5.4(b) of the
Oleoducto Central Agreement;

     (d)  In favor of all capital reductions, liquidations or split-ups
(esciciones)  or  other corporate action of the JSC required to achieve Equity
Amortization  pursuant  to  Section 5.5 of the Oleoducto Central Agreement and
all capital increases followed by capital reductions, liquidations or
split-ups  escicines  (but  not to a level lower than Cash Paid-In Equity) for
purposes  of making any Distributions pursuant to Section 5.6 thereof, in each
case, as certified by three Shareholder Parties hereto;

       (e)  In favor of the incurrence of Senior Debt by the JSC in accordance
with  the Financing Plan and Section 5.2(c) of the Oleoducto Central Agreement
as certified by the President and one member of the Board of Directors;

<PAGE>
      (f)  Against the making of any Distribution by the JSC in respect of the
three-year period ending December 31, 1997; and

        (g)  So as to ensure that no resolution of the Shareholders which does
not  fall  within  the  category of resolutions for which a 90.41% affirmative
vote is required pursuant to Article 33 of the By-laws shall be blocked by any
single Shareholder Party.

The  Voting Trustee shall in all matters act at a meeting.  The Voting Trustee
may exercise Voting Rights of Shares of the JSC in person or by such person as
it shall select as its proxy.

           Section 3.2.      Effect of Voting Default.  Upon occurrence of a
Voting  Default, the JSC shall immediately notify the Voting Trustee and until
such time that the JSC shall have notified the Voting Trustee that such Voting
Default  has  been  cured  or otherwise remedied, the Shares of the defaulting
Shareholder  Party will be represented by the Voting Trustee, and included for
purposes  of determining whether or not a quorum is present, at any meeting of
shareholders  of  the JSC or any other proceeding and, subject to Section 3.1,
the Voting Trustee will exercise the Voting Rights attaching to such Shares in
proportion to instructions given for votes to be cast by non-defaulting
Shareholder Parties without regard to any direction of the defaulting
Shareholder Party.

           Section 3.3.       Voting Default.  Voting Default shall exist with
respect to a Shareholder Party if:

     (a)   There is continuing an event of default or default under the Common
Security  Trust  Agreement  with respect to the Senior Debt Tranche secured by
Collateral provided by such Shareholder Party or members of its Initial
Shipper Group after receipt by the JSC of a notice of default in the form
provided under the Common Security Trust Agreement;

     (b)  Such Shareholder Party has failed to meet any of its payment
obligations under its Subscription Agreement or any of its duties and
obligations under this Agreement or the Dividend Trust Agreement or has
transferred Shares in violation of Article Ten of the Oleoducto Central
Agreement;

        (c)  Such Shareholder Party or any Affiliate of such Shareholder Party
has  failed  to meet any of its payment or material shipping obligations under
its  Transportation  Agreement, Transportation Notes Agreement, Advance Tariff
Agreement or any guarantee of obligations thereunder or under the Subscription
Agreement of such Shareholder Party; or

       (d)  the JSC has failed to obtain all or any portion of the Senior Debt
Tranche related to such Shareholder Party's Initial Shipper Group, has
provided such Shareholder Party with a notice of Senior Debt Shortfall
pursuant  to Section 5.2(d) of the Oleoducto Central Agreement and Senior Debt
to cover such Senior Debt Shortfall has not been provided by the date
determined in such notice.

              (b)  Each Shareholder Party agrees to execute and deliver to the

on  behalf  of such Shareholder Party that the Voting Trustee is authorized to
take pursuant to this Agreement and Colombia law in furtherance thereof.

          Section 4.4.  Reliance.  The Voting Trustee shall be entitled to act

<PAGE>
effectiveness and the truth and acceptability of any provisions contained
therein. The Voting Trustee shall not have any responsibility to make any
investigation  into  the  facts  or matters stated in any notice, certificate,
instrument,  demand, request, direction, instruction, waiver, receipt, consent
or other document or communication furnished to it hereunder. The JSC and each
Shareholder  Party shall deliver to the Voting Trustee a list duly executed by
an  officer thereof duly authorized thereunto of authorized signatories of any
notice, certificate, instrument, demand, request, direction, instruction,
waiver,  receipt,  consent or other document or communication furnished to the
Voting  Trustee hereunder, and the Voting Trustee shall be entitled to rely on
such  list until a new list is furnished by the JSC or such Shareholder Party,
as the case may be, to the Voting Trustee.

           Section 4.5.  Books and Records.  The Voting Trustee shall maintain
all such books and records as may be necessary properly to record all
transactions carried out by it under this Agreement and as required by
Colombian  law.    The Voting Trustee shall permit the Shareholder Parties and
the JSC and their authorized representatives to examine such books and
records; provided that any such examination shall occur upon reasonable notice
and  during  normal business hours. Upon request by the JSC or any Shareholder
Party, the Voting Trustee shall at any time provide such parties with any
other information such parties may reasonably request regarding the
transactions  contemplated  in this Agreement.  Upon removal or resignation of
the Voting Trustee, the Voting Trustee shall deliver all such books and
records  to  the  successor voting trustee, or, in the event of termination of
this Agreement, to the JSC.

          Section 4.6.  Liability.  The Voting Trustee shall not be liable for
any  error of judgment or for any act done or omitted to be done by it in good
faith  or  for  any mistake of fact or law, or for anything which it may do or

Shareholder  Party  or the JSC shall in no event be liable for any act done or
omitted to be done by the Voting Trustee or by any of its officers or
employees.

          Section      4.7.  Consultation With Counsel, etc.  The Voting
Trustee  may  consult with, and obtain advice from, legal counsel, accountants
and  other experts, in connection with the performance of its duties hereunder

faith in accordance with the written opinion and advice of such counsel,
accountants and other experts. The Voting Trustee shall not be responsible for

to inquire whether any notice, certificate, instrument, demand, request,
direction,

<PAGE>
instruction,  waiver,  receipt, consent, document, communication, statement or
calculation is in conformity with the terms of any such other agreement,
except  those irregularities or errors manifestly apparent on the face of such
document  or  to  the actual knowledge of the Voting Trustee. If, however, any
communication  received  by the Voting Trustee appears manifestly erroneous or
irregular  the  Voting Trustee shall be under a duty to make prompt inquiry to
the  Person  originating  such  communication in  order to determine whether a
clerical error or inadvertent mistake has occurred.

          Section 4.9.  Resignation, Replacement and Successor Voting Trustee.
  The  Voting  Trustee at any time may resign as Voting Trustee hereunder upon
giving not less than six months' notice in writing to the JSC and each
Shareholder Party. The Voting Trustee may be removed as Voting Trustee
hereunder  by  an  instrument in writing by the JSC and each Shareholder Party

of  the  Voting Trustee, a successor voting trustee shall be designated by the
JSC  and  each  Shareholder Party with respect to which there is continuing no
Voting Default. No resignation or removal of the Voting Trustee and no
designation  of  a  successor  voting trustee shall be effective until (a) the
successor  voting  trustee  has accepted its designation, (b) all indemnities,
compensation  and expenses required by Sections 4.10, 4.11 and 4.13 shall have
been  paid  or provided for and (c) the Voting Trustee shall have executed and

accepted within 60 days after the date fixed for such resignation or removal a
successor voting trustee shall be designated by the JSC and Shareholder
Parties holding a majority of the Shares subject to this trust (encargo
fiduciario).  Any successor voting trustee designated pursuant to this Section
4.9 shall be a Person eligible to act as Voting Trustee hereunder in
accordance  with  applicable  law. Any successor voting trustee shall evidence
its  acceptance  of  the trust (encargo fiduciario) hereunder by executing and
delivering to the JSC, each Shareholder Party and the Voting Trustee an
instrument  accepting  this  trust (encargo fiduciario) and its designation as
Voting Trustee hereunder, and thereupon such successor voting trustee, without
any  further act, deed or conveyance, shall become vested with all the rights,
powers,  duties  and obligations of its predecessor hereunder with like effect
as  if  originally  named as Voting Trustee herein, and such predecessor shall
have  no  further obligation or liability thereunder except for liability with
respect  to its acts or omissions prior to such succession pursuant to Section
4.6; nevertheless, on the request of any party hereto or such successor voting
trustee, the Voting Trustee ceasing to act shall execute and deliver
instruments transferring to such successor voting trustee all rights and
powers of the Voting Trustee so ceasing to act.

              Section 4.10.  Indemnity.  (a)  Each Shareholder Party agrees to
indemnify  the  Voting Trustee for, and to hold it harmless against, any loss,
liability, claim, judgment, settlement, compromise, obligation, damage,
penalty,  cost,  expense or disbursement of any kind or nature whatsoever with
respect to the execution, delivery, enforcement, performance and
administration of this Agreement, unless arising from the negligence or
willful misconduct of the Voting Trustee or any agents that are seeking
indemnification,  including the costs and expenses of defending itself against
any claim of liability in the premises.

<PAGE>
          (b)  In any suit, proceeding or action brought by the Voting Trustee
with respect to, or to enforce any provisions of this Agreement, each
Shareholder  Party  severally,  in  proportion to the number of Shares held by
such Shareholder Party to the number of Shares held by all Shareholder
Parties,  will  save,  indemnify and keep the Voting Trustee harmless from and
against all expense, loss or damage suffered by reason of any defense, setoff,
counterclaim,  recoupment  or reduction of liability whatsoever of the obligee
thereunder, arising out of a breach by the JSC or any Shareholder Party of any
of its obligations hereunder or thereunder or arising out of any other
agreement,  indebtedness or liability at any time owing to or in favor of such
obligee or its successors from the JSC or such Shareholder Party, and all such
obligations of the JSC shall be and remain enforceable against and only
against the JSC or such Shareholder Party and shall not be enforceable against
the Voting Trustee or any Shareholder.

          (c)  The agreements in this Section 4.10 shall survive the
termination of the other provisions of this Agreement.

            Section 4.11.  Compensation.  The Voting Trustee shall be entitled
to reasonable compensation (which shall not be limited by any provision of law
in  regard  to compensation of a trustee of an express trust) as may be agreed
from time to time between the JSC and the Voting Trustee for all services
rendered under this Agreement, and such compensation, together with
reimbursement of the Voting Trustee for its advances, disbursements and
expenses  in  connection with the performance of the trust provided for herein
(including the reasonable fees and expenses of its agents and of counsel,
accountants  and  other  experts referred to in Section 4.7), shall be paid by
the JSC promptly upon demand from the Voting Trustee from time to time as
services are rendered and expenses are incurred. The Shareholder Parties shall
have no liability for any fees, expenses or disbursements of the Voting
Trustee.

           Section 4.12.  Certificates.  Whenever in the administration of the
trust  created by this Agreement the Voting Trustee shall deem it necessary or
desirable  that a matter be proved or established in connection with taking or
omitting any action by the Voting Trustee hereunder, such matter (unless other
evidence  in  respect  thereof  be herein specifically prescribed) may, in the
absence of negligence or willful misconduct on the part of the Voting Trustee,
be deemed to be conclusively proved or established by a certificate of the JSC
delivered to the Voting Trustee.

              Section 4.13.  Stamp and Other Similar Taxes.  The JSC agrees to
indemnify  and  hold harmless the Voting Trustee from, and shall reimburse the
Voting Trustee for, any present or future claim for liability for any stamp or
other  similar  tax  and any penalties or interest with respect thereto, which
may  be  assessed,  levied or collected by any jurisdiction in connection with
this Agreement or the trust created hereunder. The obligations of the JSC
under  this Section 4.13 shall survive the termination of the other provisions
of this Agreement.

<PAGE>
           Section 4.14.  Exculpatory Provisions.  The Voting Trustee makes no
representations as to the value or condition of the trust created hereunder or
any part thereof or as to the validity, execution (except by itself),
enforceability, legality or sufficiency of this Agreement, and the Voting
Trustee shall incur no liability or responsibility in respect of any such
matters.

             Section 4.15.  Merger of the Trustee.  Any corporation into which
the Voting Trustee shall be merged, or with which it shall be consolidated, or
any corporation resulting from any merger or consolidation to which the Voting
Trustee  shall  be  a  party, shall be the Voting Trustee under this Agreement
without the execution or filing of any paper or any further act on the part of
the parties hereto .

            Section 4.16.  Treatment of Shareholder Parties by Voting Trustee.
(a)  The Trustee may treat the Shareholder Parties as the holders of the
Shares  and  as  the absolute owners thereof for all purposes hereunder unless
the Voting Trustee shall receive notice to the contrary.

              (b)  Any Person which shall be designated as the duly authorized
representative of one or more of Shareholder Parties to act as such in
connection  with any matters pertaining to this Agreement shall present to the
Voting Trustee such documents, including, without limitation, opinions of
counsel, as the Voting Trustee may reasonably request, in order to demonstrate
to the Voting Trustee the authority of such Person to act as the
representative of such Shareholder Party.

              (c)  The JSC shall treat the Voting Trustee as the holder of all
Voting  Rights attaching to the Shares held by the Shareholder Parties for all
purposes hereunder.

              Section 4.17.  Confidentiality.  The Voting Trustee shall assure
that  all  information  disclosed  to it concerning the Oleoducto Central, the
assets and business of the JSC and the assets and business of each of the
Shareholder Parties and not otherwise generally available ("Confidential
Information")  shall  be kept confidential and shall, unless otherwise required
by law or official request issued by a court of competent jurisdiction or by a
judicial, administrative, legislative, regulatory or self-regulatory authority
with  legal authority to make such request not be revealed without the consent
of  the  JSC and all Shareholder Parties other than to the directors, officers
and  representatives of the JSC, the Shareholder Parties and Affiliates of the
Shareholder Parties.  Upon the JSC or any Shareholder Party demanding the
return  of Confidential Information relating to it by notice in writing to the
Voting Trustee shall, and shall cause its representatives to, return all
documents  containing  Confidential Information that have been provided by the
Shareholder  Party demanding the return of Confidential Information (or on its
behalf)  and  destroy  any  copies of such documents and any document or other
record reproducing, containing or made from or with reference to the
Confidential Information, except, in each case, for any submissions to or
filings with judicial, administrative, legislative or regulatory authorities.
Such  return  or destruction shall take place as soon as practicable after the
receipt of such notice.  The agreements in this Section 4.17 shall survive the
termination of the other provisions of this Agreement.

<PAGE>
             Section 4.18.  Miscellaneous.  (a)  The Voting Trustee shall have
the  right  at  any time to seek instructions concerning the administration of
this trust from any court of competent jurisdiction. In the event of any
disagreement  between the other parties to this Agreement resulting in adverse
claims  being  made  in connection with the execution of the trust held by the
Voting  Trustee  and  the terms of this Agreement do not unambiguously mandate
the  action the Voting Trustee is to take in connection with the Voting Rights
under the circumstances then existing, or the Voting Trustee is in doubt as to
what  action  it  is required to take, the Voting Trustee shall be entitled to
refrain from taking  any  action  until directed otherwise in writing by the
Parties hereto entitled to give such direction or by a court of competent
jurisdiction.

             (b)  The Voting Trustee makes no representations as to, and shall

dealing or contracting with the JSC or any Shareholder Party either as vendor,
purchaser, depositary, lender, borrower, correspondent bank or otherwise.

and, if given by certified or registered mail, on the fifth Business Day
following the deposit thereof in the mail and, if given by electronic
communication,  on  the  day of transmittal thereof if given during the normal
business hours of the recipient and on the Business Day during which such
normal  business  hours  next occur if not given during such hours on any day.
The Party giving any notice, request, demand, direction or other communication
by electronic communication shall send the original thereof by personal
delivery or by first class mail.

          Section 6.2.  Entire Agreement.  This Agreement constitutes the
entire  Agreement  between the Parties pertaining to the subject matter hereof
and supersedes all prior agreements, understandings, negotiations and
discussions, whether oral or written, of the Parties, and there are no
warranties, representations or other agreements between the Parties in
connection  with  the  subject  matter hereof except as specifically set forth
herein  and  therein.  No amendment, supplement, waiver or termination of this
Agreement shall be binding unless executed in writing by the Party to be bound
thereby.  No waiver of any of the provisions of this Agreement shall be deemed
or  shall constitute a waiver of any other provisions (whether or not similar)
nor shall such waiver constitute a continuing waiver unless otherwise
expressly provided.

          Section 6.3.  Representations and Warranties.  Each Party represents
and warrants to the other that:

       (a)  it is a corporation duly incorporated and organized under the laws
of its jurisdiction of incorporation;

       (b)  it has the requisite power and authority to enter into and perform
its  obligations  under  this Agreement, and this Agreement, when executed and
delivered  by such Party, constitutes a valid and legally binding agreement of
such Party;

     (c)  the execution and delivery of, and the performance by it of its
obligations  under this Agreement will not result in a breach of or constitute
a default under:

<PAGE>
          (i)     any provision of its charter or articles of incorporation or
its by-laws;

          (ii)     any agreement or instrument to which it is a party and
which is material to the performance by it of its obligations hereunder;

          (iii)     any statute, rule, regulation or order, judgment or decree
of any governmental agency or court having jurisdiction over it or by which it
is bound; and

     (d)  neither it nor any of its property has any immunity from
jurisdiction of any court or from set-off or any legal process.

          Section 6.4.  Assignments.  (a)  The JSC may not assign this
Agreement or any of its rights hereunder to or in any person not a party
hereto except with the prior written consent of each Shareholder Party.

          (b)  A Shareholder Party may not assign this Agreement or any of its
Voting  Rights  or its rights hereunder to or in any person not a party hereto
except in connection with a transfer of its Shares permitted pursuant to
Article Ten of the Oleoducto Central Agreement.

           (c)  A Shareholder Party which has transferred any of its Shares to
another Person or assigned to another Person any right to acquire Shares shall
procure  that such Person shall become a Shareholder Party hereto with respect
to  such Shares by providing written notice to the Voting Trustee, which shall
then notify all other Parties hereto. Upon receipt of such notice by the
Voting  Trustee,  such holder shall have all the rights, benefits, obligations
and duties hereunder of a Shareholder Party hereto. A notice or application by
a  holder  of Shares to be registered as a shareholder of the JSC in the Share
Register  maintained by the JSC shall be deemed to also be a notice to the JSC
pursuant to this paragraph (c) of Section 6.4.

          Section 6.5.  Amendments.  This Agreement may not be amended or
modified except with the written consent of the Parties and any permitted
assignees.

the benefit of and be binding upon the Parties and their respective successors
and permitted assignees, and no other Person shall have any rights hereunder.

              Section6.7.  Severability.  If, for any reason, any provision of
this Agreement is unenforceable, the remaining provisions hereof shall
nevertheless be carried into effect.

             Section 6.8.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY
AND  CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE REPUBLIC OF COLOMBIA WITHOUT
REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS.

the Parties in connection with corporate activities, rights of the
shareholders, profit participation, liquidation of the Company or other
matters arising out of or relating to this Agreement or the performance,
breach,  termination  or  invalidity hereof, unless not in the disposal of the
Parties, shall be settled by a Court of Arbitration designated by the Board of
Directors of the Chamber of Commerce of Santafe de Bogota by drawing lots
among  the  arbitrators appearing in the list kept by the Center of Mercantile
Arbitration  and Conciliation of said Chamber. The Court thus designated shall
abide by the provisions of the Code of Civil Procedure and the Commercial Code
in  accordance with the following rules:  (A) the Court shall consist of three
arbitrators;  (B)  the  internal organization of the Court shall be subject to
the  rules established to such end by the Center of Mercantile Arbitration and
Conciliation of the Chamber of Commerce of Santafe de Bogota; (C) the decision
of the Court shall be in law; and (D) the Court shall meet in Santafe de
Bogota, at the Center of Mercantile Arbitration and Conciliation of the
Chamber of Commerce of such city.

          Section 6.10.  Waiver of Immunity.  (a)  Each Party irrevocably
consents to and waives any objection which it may now or hereafter have to the
laying  of  venue of any proceeding relating to enforcement of the arbitration
provisions of this Agreement brought in the Specified Court and further
irrevocably waives, to the fullest extent it may effectively do so, the
defense  of an inconvenient forum to the maintenance of any such proceeding in
the Specified Court.

             (b)  To the extent that a Party or any of its revenues, assets or
properties shall be entitled, with respect to any proceeding relating to
enforcement of the arbitration provisions of this Agreement at any time
brought  against  such  Party or any of its revenues, assets or properties, to
any  sovereign or other immunity from suit, from jurisdiction, from attachment
prior to judgment, from attachment in aid of execution of judgment, from
execution of a judgment or from any other legal or judicial process or remedy,
and  to  the extent that in any jurisdiction there shall be attributed such an
immunity,  such  Party  irrevocably agrees not to claim and irrevocably waives
such immunity to the fullest extent permitted by the laws of such jurisdiction
(including,  without  limitation, the Foreign Sovereign Immunities Act 1976 of
the United States).

and each Shareholder  Party.    The Dividend Trustee may be removed as Dividend
Trustee hereunder  by  an  instrument in writing by the JSC and each Shareholder
Party with respect to the Dividend Account of which there is no outstanding
Restriction  Notice.    Upon  resignation of the Dividend Trustee, a successor
dividend  trustee  shall  be  designated by the JSC and each Shareholder Party
with respect to which there is no outstanding Restriction Notice.  No
resignation or removal of the Dividend Trustee and no appointment of a
successor dividend trustee shall be effective until (a) the successor dividend
trustee  has  accepted  its designation, (b) all indemnities, compensation and
expenses required by Sections 4.10, 4.11 and 4.13 shall have been paid or
provided for and (c) the Dividend Trustee shall have executed and delivered to
the  successor trustee a notarized Colombian public deed delegating its rights
and responsibilities hereunder and under the Security Documents to the
successor  trustee.    If no designation of a successor dividend trustee shall
have been made and accepted within 60 days after the date fixed for such
resignation or removal a successor dividend trustee shall be designated by the
JSC  and  Shareholder Parties holding a majority of the Shares subject to this
Agreement  and  if no successor dividend trustee shall have been so designated
and  shall  have  accepted such designation within an additional 30 days after
the  date fixed for such resignation or such removal, the Dividend Trustee may
petition any court of competent jurisdiction for the designation of a
successor  dividend  trustee.  Such court may thereupon, after such notice, if
any, as it may prescribe, designate a successor dividend trustee.  Any
successor  dividend  trustee appointed pursuant to this Section 4.9 shall be a
bank or trust company organized under the laws of [________] having its
principal  corporate  trust  office in [insert office location] and a combined
capital surplus of at least $200,000,000.  Any successor dividend trustee
shall evidence its acceptance of the trust hereunder by executing and
delivering to the JSC, each Shareholder Party and the Dividend Trustee an
instrument accepting this trust and its designation as Dividend Trustee
hereunder,  and thereupon such successor dividend trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers,
duties  and  obligations  of  its predecessor hereunder with like effect as if
originally  named  as Dividend Trustee herein, and such predecessor shall have
no further obligation or liability thereunder except for liability with
respect  to its acts or omissions prior to such succession pursuant to Section
4.6; nevertheless, on the request of any party hereto or such successor
dividend trustee, the Dividend Trustee ceasing to act shall execute and
deliver instruments transferring to such successor dividend trustee all rights
and powers of the Dividend Trustee so ceasing to act, including any such
instruments necessary to transfer the Dividend Account maintained for the
benefit of each Shareholder Party to such successor dividend trustee, and
shall  deliver  to  such successor dividend trustee all property held by it in
trust hereunder.

Dividend  Trustee  for,  and to hold it harmless against, any loss, liability,
claim,  judgment,  settlement,  compromise, obligation, damage, penalty, cost,
expense  or  disbursement of any kind or nature whatsoever with respect to the
execution, delivery, enforcement, performance and administration of this
Agreement,  unless forming part of the compensation agreed pursuant to Section
4.11  or    arising from the gross negligence or willful misconduct of such of
the Dividend Trustee or the agents that are seeking indemnification, including
the  costs  and expenses of defending itself against any claim of liability in
the premises.

          (b)  In any suit, proceeding or action brought by the Dividend
Trustee  with  respect to, or to enforce any provisions of this Agreement, the
JSC will save, indemnify and keep the Dividend Trustee harmless from and
against all expense, loss or damage suffered by reason of any defense, setoff,
counterclaim,  recoupment  or reduction of liability whatsoever of the obligee
thereunder, arising out of a breach by the JSC of any of its obligations
hereunder or thereunder or arising out of any other agreement, indebtedness or
liability  at  any time owing to or in favor of such obligee or its successors
from the JSC, and all such obligations of the JSC shall be and remain
enforceable against and only against the JSC and shall not be enforceable
against the Dividend Trustee or any Shareholder.

          (c)  The agreements in this Section 4.10 shall survive the
termination of the other provisions of this Agreement.

          Section 4.11.  Compensation.  The Dividend Trustee shall be entitled
to reasonable compensation (which shall not be limited by any provision of law
in  regard  to compensation of a trustee of an express trust) as may be agreed
from  time  to  time between the JSC and the Dividend Trustee for all services
rendered under this Agreement, and such compensation, together with
reimbursement of the Dividend Trustee for its advances, disbursements and
expenses  in  connection with the performance of the trust provided for herein
(including the reasonable fees and expenses of its agents and of counsel,
accountants  and  other  experts referred to in Section 4.7), shall be paid by
the  JSC  promptly  upon demand from the Dividend Trustee from time to time as
services  are  rendered and expenses are incurred. The Shareholders shall have
no liability for any fees, expenses or disbursements of the Dividend Trustee.

           Section 4.12.  Certificates.  Whenever in the administration of the
trusts of this Agreement the Dividend Trustee shall deem it necessary or
desirable  that a matter be proved or established in connection with taking or
omitting  any  action  by  the Dividend Trustee hereunder, such matter (unless
other  evidence  in respect thereof be herein specifically prescribed) may, in
the  absence  of  negligence or willful misconduct on the part of the Dividend
Trustee,  be  deemed to be conclusively proved or established by a certificate
of the JSC delivered to the Dividend Trustee.

<PAGE>
              Section 4.13.  Stamp and Other Similar Taxes.  The JSC agrees to
indemnify and hold harmless the Dividend Trustee from, and shall reimburse the
Dividend  Trustee for, any present or future claim for liability for any stamp
or other similar tax and any penalties or interest with respect thereto, which
may  be  assessed,  levied or collected by any jurisdiction in connection with
this  Agreement  or  the  trusts created hereunder. The obligations of the JSC
under  this Section 4.13 shall survive the termination of the other provisions
of this Agreement.

            Section 4.14.  Exculpatory Provisions.  The Dividend Trustee makes
no representations as to the value or condition of the trusts created
hereunder or any part
thereof,  or  as to the title of the JSC or any Shareholder Parties thereto or
as  to the validity, execution (except by itself), enforceability, legality or
sufficiency of this Agreement, and the Dividend Trustee shall incur no
liability or responsibility in respect of any such matters.

             Section 4.15.  Merger of the Trustee.  Any corporation into which
the  Dividend Trustee shall be merged, or with which it shall be consolidated,
or  any  corporation  resulting  from any merger or consolidation to which the
Dividend  Trustee  shall  be a party, shall be the Dividend Trustee under this
Agreement  without  the execution or filing of any paper or any further act on
the part of the parties hereto.

           Section 4.16.  Treatment of Shareholders by Dividend Trustee.  (a)
The Trustee may treat the Shareholder Parties as the holders of the Shares and
as  the absolute owners thereof for all purposes hereunder unless the Dividend
Trustee shall receive notice to the contrary.

              (b)  Any Person which shall be designated as the duly authorized
representative of one or more of a Shareholder Party to act as such in
connection  with any matters pertaining to this Agreement shall present to the
Dividend  Trustee  such  documents, including, without limitation, opinions of
counsel, as the Dividend Trustee may reasonably request, in order to
demonstrate to the Dividend Trustee the authority of such Person to act as the
representative of such Shareholder Party.

            Section 4.17.  Confidentiality.  The Dividend Trustee shall assure
that  all  information  disclosed  to it concerning the Oleoducto Central, the
assets and business of the JSC and the assets and business of each of the
other  Shareholder Parties and not otherwise generally available (Confidential
Information)  shall  be kept confidential and shall, unless otherwise required
by law or official request issued by a court of competent jurisdiction or by a
judicial, administrative, legislative, regulatory or self-regulatory authority
not  be  revealed  without  the consent of the JSC and all Shareholder Parties
other than to the directors, officers and representatives of the JSC, the
Shareholder  Parties  and Affiliates of the Shareholder Parties.  Upon the JSC
or any Shareholder Party demanding the return of Confidential Information
relating to it by notice in writing the Dividend Trustee shall, and shall
cause  its  representatives  to,  return all documents containing Confidential
Information  that have been provided by the JSC or Shareholder Party demanding
the return of Confidential Information (or on its behalf) and destroy any
copies of such documents and any document or other record reproducing,
containing  or  made  from  or with reference to the Confidential Information,
except, in each case, for any submissions to or filings with judicial,
administrative, legislative or regulatory authorities. Such return or
destruction shall

<PAGE>
take place as soon as practicable after the receipt of such notice.  The
agreements in this Section 4.17 shall survive the termination of the other
provisions of this Agreement.

           Section 4.18.  Miscellaneous.  (a)  The Dividend Trustee shall have
the  right  at  any time to seek instructions concerning the administration of
this trust from any court of competent jurisdiction. In the event of any
disagreement  between the other parties to this Agreement resulting in adverse
claims being made in connection with property held by the Dividend Trustee and
the terms of this Agreement do not unambiguously mandate the action the
Dividend Trustee is to take in connection with such property under the
circumstance  then  existing,  or  the Dividend Trustee is in doubt as to what
action it is required to take, the Dividend Trustee shall be entitled to
refrain from taking any action until directed otherwise in writing by the
Parties hereto entitled to give such direction or by a court of competent
jurisdiction.

           (b)  None of the provisions of this Agreement shall be construed to
require  the  Dividend Trustee to expend or risk its own funds or otherwise to
incur any personal financial liability in the performance of any of its duties
hereunder  or  thereunder  if it shall have reasonable grounds for belief that
repayment  of  such  funds  or indemnity against such risk or liability is not
reasonably assured to it.

           (c)  The Dividend Trustee makes no representations as to, and shall
have  no responsibility for, the correctness of any statement contained in, or
the validity or sufficiency of, this Agreement or any documents or instruments
referred to herein, or as to or for the validity or collectibility of any
obligation  contemplated  hereby or thereby. The Dividend Trustee shall not be
accountable for the use or application by any Person of disbursements properly
made by the Dividend Trustee in conformity with the provisions of this
Agreement.

            (d)  The Dividend Trustee (or any parent, subsidiary or associated
person)  may  accept deposits from, lend money to, and generally engage in any
business  with, the JSC, any Shareholder Party, the Subaccount Banks or any of
their  Affiliates, without affecting the validity of the trusts created hereby
or the right to enforce any right to payment hereunder as freely as if it were
not  the Dividend Trustee hereunder. The Dividend Trustee shall notify the JSC
and each Shareholder Party at any time it believes it has any interest
conflicting with its obligations hereunder. The Trustee hereby waives any
right of banker's lien, set-off or counterclaim in respect of any assets
contained in the Dividend Accounts maintained for the benefit of a Shareholder
Party  or  otherwise that are held by the Dividend Trustee as dividend trustee
hereunder.

          (e)  The Trustee shall not be personally liable for debts contracted
or liabilities or damages incurred in the management or operations of the
trust  hereunder,  except  for those contracted or incurred as a result of its
gross negligence or willful misconduct.

            Section 6.2.  Entire Agreement.  This Agreement, together with the
Oleoducto Central Agreement, constitutes the entire Agreement between the
Parties pertaining to the subject matter hereof and supersedes all prior
agreements, understandings, negotiations and discussions, whether oral or
written, of the Parties, and there are no warranties, representations or other
agreements  between  the  Parties in connection with the subject matter hereof
except as specifically set forth herein and therein.  No amendment,
supplement,  waiver  or  termination of this Agreement shall be binding unless
executed  in writing by the Party to be bound thereby. No waiver of any of the
provisions  of  this Agreement shall be deemed or shall constitute a waiver of
any other provisions (whether or not similar) nor shall such waiver constitute
a continuing waiver unless otherwise expressly provided.

          Section 6.3.  Representations and Warranties.  Each Party represents
and warrants to the other that:

       (a)  it is a corporation duly incorporated and organized under the laws
of its jurisdiction of incorporation;

       (b)  it has the requisite power and authority to enter into and perform
its  obligations  under  this Agreement, and this Agreement, when executed and
delivered  by such Party, constitutes a valid and legally binding agreement of
such Party;

     (c)  the execution and delivery of, and the performance by it of its
obligations  under this Agreement will not result in a breach of or constitute
a default under:


               (i)     any provision of its charter or articles of
incorporation or its by-laws;

               (ii)     any agreement or instrument to which it is a party and
which is material to the performance by it of its obligations hereunder;

                 (iii)     any statute, rule, regulation or order, judgment or
decree  of  any governmental agency or court having jurisdiction over it or by
which it is bound; and

     (d)  neither it nor any of its property has any immunity from
jurisdiction of any court or from set-off or any legal process.

          Section 6.4.  Assignments.  (a) The JSC may not assign this
Agreement  or  any  of its rights or proceeds hereunder, or create enforceable
third  party rights herein, to or in any person not a party hereto except with
the prior written consent of each Shareholder Party.  If each Shareholder
Party  consents,  it  agrees to execute and deliver all consents and documents
reasonably necessary to effect such assignment and to create a valid and
perfected interest herein. The claims and rights of each such Permitted
Assignee  shall  rank  pari  passu with the claims and rights of all permitted
assignees irrespective of the time or times at which prior, concurrent or
subsequent  assignments under this Section 6.4 are made or perfected.  Subject
to compliance with the terms of any such assignment, any such Permitted
Assignee shall have the rights of the JSC and may enforce such rights
hereunder as if such Permitted Assignee were a party hereto.

<PAGE>
          (b)  A Shareholder Party may not assign this Agreement or any of its
rights or proceeds hereunder or its interest in the Dividend Account
maintained for its benefit by the Dividend Trustee, or create enforceable
third  party  rights herein or therein, to or in any person not a party hereto
except  in  connection with a transfer of Shares permitted pursuant to Article
Ten of the Oleoducto Central Agreement.  A Shareholder Party which has
transferred  any of its Shares to another Person or assigned to another Person
any right to acquire Shares shall procure that such Person shall become a
Shareholder Party hereto with respect to such Shares by providing written
notice to the Dividend Trustee, which shall then notify all other Parties
hereto.  Upon receipt of such notice by the Dividend Trustee, such holder
shall  have  all  the  rights, benefits, obligations and duties hereunder of a
Shareholder  Party hereto. A notice or application by a holder of Shares to be
registered as a shareholder of the JSC in the Share Register maintained by the
JSC  shall be deemed to also be a notice to the JSC pursuant to this paragraph
(c) of Section 6.4.

           (c)  In the event of a transfer or assignment pursuant to paragraph
(b)  above by a Shareholder Party during the Restricted Period with respect to
the  Restricted  Account, the Restricted Period shall continue with respect to
such  account and funds therein shall be applied accordingly.  Notwithstanding
Section  2.1, no Dividend Account shall be established by the Dividend Trustee
for  the  benefit of any such transferee or assignee of such Shareholder Party
prior  to  the termination of the Restricted Period and the Restricted Account
shall  be deemed to be maintained by the Dividend Trustee also for the benefit
of any such transferee or assignee.

            Section 6.5.  Nature of Obligations.  Subject to the terms of this
Agreement,  the  obligations  under  this Agreement shall be unconditional and
absolute  and  shall not be deferred, excused, released, discharged, or in any
way affected by:  (i) any right of set off, counterclaim, or defense by reason
of  any  claims  against  the JSC arising under this Agreement or on any other
account whatsoever, (ii) any insolvency, bankruptcy, receivership,
reorganization, dissolution, or liquidation of the JSC or any Shareholder
Party, (iii) any sale or other transfer by any of the Shareholders (among
themselves or otherwise) of any of the JSC's capital stock, or (iv) any
change,  waiver, extension, indulgence, or other action or omission in respect
of any of the JSC's obligations in each case, whether or not the Parties shall
have had any notice or knowledge of any of the foregoing.

          Section 6.6.  Amendments.  This Agreement may not be amended or
modified except with the written consent of the Parties and any permitted
assignees.

          Section 6.7.  No Third Party Beneficiaries.  Except as herein
otherwise  expressly  provided  to the contrary, this Agreement shall inure to
the benefit of and be binding upon the Parties and their respective successors
and permitted assignees, and no other Person shall have any rights hereunder.

             Section 6.8.  Severability.  If, for any reason, any provision of
this Agreement is unenforceable, the remaining provisions hereof shall
nevertheless be carried into effect.

<PAGE>
             Section 6.9.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY
AND  CONSTRUED  IN  ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS.

           Section 6.10.  Commercial Obligations.  The Parties acknowledge and
agree that their rights and obligations hereunder are commercial and not
governmental in nature.

          Section 6.11.  Arbitration.  Any dispute, controversy or claim
arising out of or relating to this Agreement, or the performance, breach,
termination, or invalidity hereof, shall be settled by arbitration in
accordance  with the UNCITRAL Arbitration Rules in effect on the date hereof.
The  arbitration  shall  be the sole and exclusive forum for resolution of the
dispute, controversy or claim, and the award shall be final and binding.
Judgment  thereon  may be entered by any court having jurisdiction. The number
of arbitrators shall be three, each of whom shall be disinterested in the
dispute,  controversy  or claim, and shall have no connection with any party.
Should  the  services  of an appointing authority be necessary, the appointing
authority  shall be the American Arbitration Association.  The Parties and the
appointing authority may appoint from among the nationals of any country,
whether or not a party is a national of that country. The place of arbitration
shall  be  The City of New York, New York.  The arbitration shall be conducted
in  the  English language and any foreign-language documents presented at such
arbitration shall be accompanied by an English translation thereof. The
arbitrators  shall  apply the law of New York without regard to the principles
of conflicts of laws.

          Section 6.12.  Submission to Jurisdiction; Consent to Service.  Each
of the Parties hereto hereby submits to the exclusive jurisdiction of the
United States District Court for the Southern District of New York (the
"Specified Court") with respect to the enforcement of the arbitration
provisions of this Agreement and the non-exclusive jurisdiction of such courts
with  respect to the enforcement of any award thereunder.  Each of the parties
hereto irrevocably appoints the person opposite its name in Section 6.1 as its
authorized agent in the Borough of Manhattan in The City of New York upon
which process may be served in any related suit or proceeding, and agrees that
service of process upon such agent, and written notice of said service to such
party,  by the person serving the same to the address provided in Section 6.1,
shall  be deemed in every respect effective service of process upon such party
in  any such suit or proceeding.  Each of the Parties hereto further agrees to
take  any  and all action as may be necessary to maintain such designation and
appointment  of  such  agent in full force and effect for the duration of this
Agreement.

            The obligation of a Party in respect of any sum due from it to the
other  party hereunder expressed in United States dollars, notwithstanding any
judgment in a currency other than United States dollars, shall not be
discharged until the first Business Day following receipt by such Party of any
sum  adjudged  to  be  so due in such other currency on which (and only to the
extent that) such Party may in accordance with normal banking procedures
purchase  United States dollars with such other currency; if the United States
dollars so purchased are less than the sum originally due to such Party
hereunder, the other party agrees, as a separate obligation and
notwithstanding any such judgment, to indemnify such Party against such dollar
shortfall.  If the United States dollars so purchased are greater than the sum
originally due to such party hereunder, such Party agrees to pay to the

<PAGE>
other Party an amount equal to the excess of the dollars so purchased over the
sum originally due to such Party hereunder.

            Section 6.13.  Waiver of Immunity.  (a)  The Purchaser irrevocably
consents to and waives any objection which it may now or hereafter have to the
laying  of  venue of any proceeding relating to enforcement of the arbitration
provisions of this Agreement brought in the Specified Court and further
irrevocably waives, to the fullest extent it may effectively do so, the
defense  of an inconvenient forum to the maintenance of any such proceeding in
the Specified Court.

          (b)  To the extent that the Purchaser or any of its revenues, assets
or  properties  shall  be entitled, with respect to any proceeding relating to
enforcement of the arbitration provisions of this Agreement at any time
brought against the Purchaser or any of its revenues, assets or properties, to
any  sovereign or other immunity from suit, from jurisdiction, from attachment
prior to judgment, from attachment in aid of execution of judgment, from
execution of a judgment or from any other legal or judicial process or remedy,
and  to  the extent that in any jurisdiction there shall be attributed such an
immunity, the Purchaser irrevocably agrees not to claim and irrevocably waives
such immunity to the fullest extent permitted by the laws of such jurisdiction
(including,  without  limitation, the Foreign Sovereign Immunities Act 1976 of
the United States), except, in the case of Ecopetrol, as provided under
Article 684 of the Codigo de Procedimiento Civil of Colombia.

[Dividend Trustee]
[Address]


Attention:

Gentlemen:

          This is to confirm our agreement with you as follows:

             1.  The Dividend Subaccount; No Set-Offs.  We have today opened a
segregated  account  in  your name, no. _______ (the "Dividend Subaccount").  We
acknowledge  that  all  funds  or other assets in such account are trust funds
held  by  you  under  the Dividend Trust Agreement, dated as of _____________,
1994,  among  Oleoducto  Central S.A. (the JSC) and the other parties thereto,
which  trust  funds  we will hold as your custodian.  Accordingly, we will not
have, and hereby waive, any right of banker's lien, set-off or counterclaim in
respect of any funds or other assets in the Dividend Subaccount or any Special
Account (as defined below).

          [2.  Consent to Assignment.  We acknowledge and consent to the
assignment  of such interest or rights (if any) as the JSC may have in or with
respect to the Dividend Trust Subaccount or any Special Account.]

           3.  Investments.  (a)  We agree to remit all funds and other assets
held  in  or  for the Dividend Subaccount or any Special Account to you or any
person  designated  by you upon receipt of your instructions following receipt
of  any  funds or assets for deposit to the Dividend Subaccount or any Special
Account.

          (b)  We shall have no liability with respect to investments
(including  purchases or conversions of foreign exchange) of moneys held in or
for  the  Dividend  Subaccount or any Special Account (or any losses resulting
therefrom)  made  at  your direction.  Investments which we make with Dividend
Subaccount or Special Account balances will be held by us in your name.

          (c)  If, in addition to the Dividend Subaccount, we have opened
other  accounts  in  your name and we receive funds from you or the JSC or for
your,  the  JSC's  or a Shareholder Party's account that are not identified as
funds for deposit in the

<PAGE>
Dividend Subaccount or any such other account, and as to which we have
received no instructions from you, we shall deposit such funds to a segregated
account established by us in your name at such time and for such purpose
("Special  Account")  and promptly thereafter we shall request that you instruct
us as to the deposit or other disposition of such funds.

            4.  Books and Accounts.  (a)  We shall maintain all such accounts,
books and records as may be necessary properly to record all transactions
carried  out by us under this Agreement.  We shall permit you, the Shareholder
Parties and the JSC and their authorized representatives to examine such
accounts,  books  and  records; provided that any such examination shall occur
upon reasonable notice and during normal business hours.

          (b)  On or before the fifth banking day in [New York] of each
calendar month for so long as such Dividend Subaccount and any Special Account
are  open,  we shall deliver to you a statement indicating the amount of funds
and other assets on deposit in the Dividend Subaccount and such Special
Account and the nature of any investments thereof as of the end of the
preceding calendar month and identifying all deposits to and payments from the
Dividend Subaccount and such Special Account during such calendar month,
including  the  date  on  which made.  Upon your request, we will at any other

the withdrawal and transfer of moneys in the Dividend Subaccount or any
Special Account may be given by you in writing, by telephone, by tested telex,
facsimile  or other form of electronic transmission, and in any manner that we
may reasonably accept (subject to normal and customary verification
requirements),  in  each case from persons designated for such purpose by you,
and under procedures established from time to time by you and us.  Any
initiation of a wire transfer of funds in the Dividend Subaccount or any
Special  Account effected through computerized facilities offered to you by us
shall  be  deemed to be the giving to us of a direction or instruction to make
such  transfer.  All directions, notices and instructions given to us that are
not in writing or by electronic funds transfer shall be confirmed in writing.

              6.  Duties of Subaccount Bank.  (a)  We shall be entitled to act
upon  any  notice, request, direction, waiver, receipt or other document which
in  good faith we believe to be genuine, and we shall be entitled to rely upon
the due execution, validity and effectiveness, and the truth and acceptability

make any investigation into the facts or matters stated in any notice,
certificate,  instrument, demand, request or other communications furnished to
us hereunder.
          (b)  We shall not be liable for any error of judgment or for any act
done  or omitted by us in good faith or for any mistake of fact or law, or for
anything  which we may do or refrain from doing, except for our own negligence
or willful misconduct.

              (c)  We may consult with, and obtain advice from, legal counsel,
accountants and other experts, in connection with the performance of our
duties  hereunder and we shall incur no liability and shall be fully protected
in  acting  in  good  faith in accordance with the written opinion and written
advice of such counsel, accountants and other experts. We shall

misconduct.

          (d)  We shall have no duties other than those specifically set forth
or  provided  for in this Agreement and no implied covenants or obligations on
our  part  shall  be  read into this Agreement. We shall have no obligation to
familiarize  ourselves  with  and shall have no responsibility with respect to
any other agreement relating to the transactions contemplated by this
Agreement nor any obligation to inquire whether any notice, instruction,
statement  or  calculation  is  in conformity with the terms of any such other
agreement,  except  those  irregularities or errors manifestly apparent on the
face  of such document or to our actual knowledge. If, however, any remittance
or  communication  received by us appears manifestly erroneous or irregular we
shall  be  under  a duty to make prompt inquiry to the person originating such
remittance  or communication in order to determine whether a clerical error or
inadvertent mistake has occurred. We shall at all times take such care in
dealing  with the Subaccount and any Special Account as would a prudent man in
dealing with his own property.

           7.  Expenses.  We acknowledge that you shall have no responsibility
for  any  fees  or expenses incurred by us in connection with this Agreement.

                                                   OLEODUCTO CENTRAL AGREEMENT

                             OPERATING PRINCIPLES


1.0     INTRODUCTION

The Parties agree that the Oleoducto Central Operations Agreement will
establish  the  contractual relationship between the JSC and the Operator, and
that  such  agreement  shall give effect to the operating principles set forth
below. The rights and obligations of the Canadian Group as Operator are
separate from the rights and obligations of the Canadian Group as
Shareholders.

2.0     OPERATING FEES

The  JSC shall pay the Operator all Operating and Maintenance Costs including:
(a) a fee of $2.5 million U.S. annually for the years 1996 and following
("Operating Fee") and (b) the incentives as described below.

3.0     INCENTIVES

The Parties agree that incentives shall be those which would reward the
Operator's achievements against mutually agreed targets and the Annual
Operating  Budget, recognize exceptional performance and also share in further
JSC cost savings or cost avoidance. The targets and budget shall be set
annually,  keeping  in  mind such things as; the Canadian Group's stature as a
world class operator, the assets being operated, the operating environment and
other  pipeline  operations both in Colombia and world wide. The Operator will
apply  North  American  technology  and management techniques to achieve these
levels  of  performance.    The operating incentive shall be recognized in two
categories:

  Quality Incentives - which are two fold:  Base and "Stretch" Incentives; and

  Profit Sharing

The  Operator incentives from the Quality Incentive programs start in 1998 and
shall,  together  with  the Operating Fee, the Subordinated Fee and the agreed
return on equity determined in accordance with Section 5.4(b) of the Oleoducto
Central  Agreement,  be  capped to yield a maximum 16% ROE after tax return in
1998  and 1999 and 17% ROE after tax return in 2000 and thereafter on Canadian
Group  Adjusted  Paid-In  Equity, irrespective of any invested capital arising
from the acquisition of another shareholder's interest or funding another
shareholder's  interest.    For the purposes of determining the Base Incentive
only,  the Operating Fee will be calculated on an after tax basis, and will be
calculated as an annual return net of all Colombian Taxes on the Adjusted
Paid-In  Equity.   The Profit Sharing program would not be capped nor included
in the Quality Incentive program.

<PAGE>
4.0     QUALITY INCENTIVES

These incentives are related to the evaluation of the technical performance of
the Operator and its ability to deliver this performance under an agreed
budget.    Performance shall be expressed among the major areas of interest to
the Initial Shippers, for example:

1)     Technical Integrity;

2)     Safety/Environment/Security/Emergency Response;

3)     Operating Performance; and

4)     Initial Shippers satisfaction as seen by the Initial Shippers after
      discussions with the Operator.

Relevant  measures for these mutual targets will be established by the Initial
Shippers and will include, but will not be limited to audits, benchmarks,
statistics and technical evaluations.

4.A     BASE INCENTIVES

The base incentive shall recognize the achievement of the mutually agreed
targets  and budget.  The founding principle of the base incentive is that the
Initial Shippers must provide the important performance factors and the
relative weighting of each of these factors for any operating year.  The
anticipated  process  for  establishing  the annual base incentive shall be as
follows:

1)        Annually, the Initial Shippers shall provide to the Operator the key
factors           and the relative weighting of each factor.

2)     The Operator and Initial Shippers shall determine preliminary
measurable           achievement targets.

3)     The Operator shall budget to reflect the factors and targets.

4)     The Operator and Initial Shippers shall determine mutually the final
       factors, weighting targets and budget prior to the start of the
operational           year.

Considering the present evaluation of the project costs, the expected
incremental ROE would be 1.3% ROE.

4.B     "STRETCH" INCENTIVE

The additional incentive will recognize exceptional performance by the
Operator  considering  an  overall  package of performance factors which shall
include incentives and disincentives.  These performance factors could include
high  performance  stretch targets in the same areas identified under the base
incentive  or could be additional and different operational factors.  The full
achievement of these factors under this stretch incentive could

<PAGE>
reach a maximum of 1% ROE.  Even after the application of the disincentives
the "stretch" incentives cannot be less than zero.

4.C     EXAMPLES OF BASE AND "STRETCH" INCENTIVES

For  the  concept  of sliding scale operating incentives to be successful, the
factors  and relative weighting must be identified at a time just prior to the
operational  target  year to reflect the business needs and priorities at that
time.    Recognizing  this premise, the following table is provided as a broad
list  of examples to illustrate the two forms of incentives for a hypothetical
target year when the expected incremental base incentive is 1.5% ROE:

<TABLE>
<CAPTION>

<S>                                 <C>          <C>
                                    INCENTIVES
FACTOR                              BASE                   "STRETCH"
Safety, Security and Environmental    0 to 0.4
Operating Performance/Costs           0 to 0.4   other items 0 to +Z
Maintenance Capital Costs             0 to 0.2                    --
Emergency Response                          --   some items -X to +Y
Technical Integrity                         --   other items 0 to +Z
Service Capacity                      0 to 0.3                    --
Petroleum Quality                     0 to 0.2                    --
Shipper Satisfaction                        --                    --
TOTAL                                      1.5%       -0.5% TO + 1.5%

</TABLE>

The specific measurement criteria for each operational factor would be
established and finalized at the approval of the budget.

The  cumulative  reward under the Stretch Incentive shall range from a minimum
of 0% to a maximum of 1% ROE even though the proposed scale is exceeded on the
upside and on the downside.

5.0     PROFIT SHARING

Should  the benefits to the Initial Shippers resulting from the actions of the
Operator  be greater than reasonably envisaged at the time that annual targets
are  set, a profit sharing principle will be implemented.  Profit sharing will
recognize any identified initiatives by the Operator, and agreed by the
Initial  Shippers, which could include one-time "bright ideas" which result in
identified savings in:

(a     lower operating expenses;

<PAGE>
(b)     reduced normalized operating expenses (taking into account annual
shipping  volume  differential,  inflation, and exceptional one-time operating
expense items) compared to an agreed rolling average (e.g. 3 years); and

(c)     capital expenditure reductions or avoidance.

A formula in the spirit of the following formula would be used for profit
sharing.    Such  formula  will be reset by Initial Shippers after discussions
with the Operator from time to time.

                      PROPOSED OPERATOR SHARING EXAMPLE

                            35% on the first $2.5M

                            20% on the next $1.25M

                        10% on any amounts over $3.75M

6.0     FORM OF PAYMENT

All  of  the  operating fees and incentives shall be Operating and Maintenance
Costs paid to the Canadian Group as Operator.  The U.S. $2.5 million operating
fee  will be paid on a pre tax basis.  The base and additional incentives will
be  paid  to yield the return after all Colombian Taxes referenced above while
any profit sharing would be paid on a pre-tax basis.

7.0     OPERATING PARAMETERS

The  JSC shall appoint the Canadian Group as operator for the operations phase
of the JSC, either under the terms of a pipeline operating agreement made
between  the  JSC and the Canadian Group or under some other arrangement.  The
pipeline  operating  agreement  or other arrangement shall contain those terms
commonly  found  in agreements or arrangements of a similar nature which inter
alia will provide the Canadian Group with the autonomy and accountability
necessary to ensure that the system is operated in an efficient, safe and
environmentally sound manner.  More specifically the Canadian Group as
operator will be responsible for:

(a)     Budgets

       preparation of annual capital and operating budgets for approval of the
JSC;

     authority to execute the approved budgets;

     preparation of accounting information and maintenance of accounting
books;

     authority for emergency expenditures for unapproved budget items;

<PAGE>
(b)     Operations of the Project

     developing and implementing materials and operations performance
standards and all related quality control program;

     developing and ensuring implementation of operations and maintenance
procedures, including safety and environmental standards (subject to the
participation of the Initial Shippers as referred to below);

     responsibility for oil movements and scheduling;

     responsibility for equipment and right-of-way maintenance;

     oil accounting and tariff management.

(c)        Human Resources (within the Board of Directors approved budgets and
manpower plans)

     organization structure and number of staff for operations entity, but the
Senior  Manager  and  direct  reports will be nominated by the Operator to the
Board of Directors for its approval;

     developing and specifying qualifications for staff positions and training
standards of operations entity;

     hiring and terminating staff of operations entity.

In  addition  to these terms commonly found in agreements or arrangements of a
similar nature, the pipeline operating agreement shall provide for:

     optimization of Colombian content;

     the sub-contracting to Ecopetrol of certain day-to-day operations.

The Parties agree the pipeline will be constructed, operated and maintained in
accordance with applicable regulations, codes and standards and that
expenditures necessary to meet these standards will be approved as required.

Standards  for  environmental  compliance,  emergency and spill response (both
onshore and offshore) and spill clean-up procedures shall be established
jointly  by the Initial Shippers and the Canadian Group.  The Initial Shippers
shall  have powers to ensure that the Canadian Group as operator complies with
such standards and procedures.

It  is  intended that the Canadian Group's appointment as operator will be for
an  initial  term  of 15 years commencing in 1995, with options to extend this
term  by  not  more than two additional five year periods plus such additional
periods required to cover Equity Amortization of the Canadian Group's
investment.    Each  such option shall be deemed to have been exercised unless
the Initial Shippers, acting by a decision of three of four Initial

<PAGE>
 Shippers, decide not to exercise it and give the Canadian Group one year's
notice of their decision.

If  the  Initial Shippers fail to exercise any such option, the Canadian Group
shall be entitled to their reasonable demobilization costs and Equity
Amortization will commence on the expiry of the term of the operatorship.

The  Canadian  Group  shall  be entitled to resign as operator on at least one
year's notice.

Notwithstanding the foregoing, the Initial Shippers shall be entitled (but not
obligated)  to  terminate  the Canadian Group's appointment as operator at any
time if any of the following conditions is satisfied:

(i)     insolvency (to be defined in the Oleoducto Central Operations
Agreement)  of the operating company or either ultimate parent of the Canadian
Group;

(ii)     gross negligence or wilful misconduct of the Canadian Group with
respect  to the Oleoducto Central Operations Agreement or other arrangement as
referred to above, determined in the reasonable judgment of the Initial
Shippers;

(iii)     non-performance or a materially sub-standard performance by the
Canadian  Group,  determined  in  the sole discretion of the Initial Shippers,
which  is not remedied within a reasonable time of the Initial Shippers giving
notice to the Canadian Group requiring it to be remedied.

Termination of the Canadian Group's appointment as Operator pursuant to either
of the preceding paragraphs will not entitle the Canadian Group to any
reimbursement  of demobilization costs or indemnity, nor will such termination
alter  any schedule for Equity Amortization of the Canadian Group's investment
that may be in effect.

The Parties acknowledge Colombian content as a key element of the JSC and
intend that as many management positions as possible should be filled by
Colombian  nationals,  whilst recognizing the need for certain positions to be
filled  by  secondees of the Canadian Group.  Colombian content also refers to
maximizing the JSC's use of Colombian contractor and suppliers.


8.0     ARBITRATION

In the event that any of the incentives become matters of dispute, the
arbitration provisions of the Oleoducto Central Agreement shall be applicable.

9.0     INSURANCE

The JSC will take out appropriate insurance insofar as such insurance is
available  on  reasonable terms.  The costs (premiums and deductibles) of this
insurance  will  be  considered  as an operating expense and will be recovered
through  the  tariff.   The events and circumstances covered by such insurance
shall include but not be limited to acts of God,

<PAGE>
accidents, sabotage, civil disturbance, terrorism, curtailment of utilities
and, insofar as insurance is available, curtailment of supplies of materials
and services.  Such events and circumstances shall not include shortage of
labor, strike, lockout, picketing or other industrial disturbances or
disputes.

10.0     FACILITIES

The Parties intend that the Canadian Group will operate:

1.     Cusiana Pump Station - including pumps, meters, and tanks

2.     Cusiana to El Porvenir Segment - first the 20" pipeline and then
beginning mid-year 1997 the new 30" pipeline

3.       El Porvenir - operate the pump station under subcontract to Ecopetrol
including the pumps, meters and tanks

4.     Miraflores - operate pump station under subcontract to Ecopetrol

5       .El Porvenir to Vasconia Segment - operate the pipeline, initially the
30"  pipeline  between La Belleza and Vasconia and the pig trap in La Belleza,
but  eventually the additional 30" pipeline between El Porvenir and La Belleza
which will be constructed under the JSC

6.     Vasconia II - operate both ODC and JSC assets in Vasconia II. This
operation  may  be  conducted directly by the Canadian Group by subcontract to
Ecopetrol

7.     ODC Pipeline - operate the pipeline between Vasconia and Caucasia
including the pump station in Caucasia and the ODC terminal facilities at
Covenas (tank farm)

8.     ODC Loop - operate the 30" pipeline between Vasconia and Covenas
including new JSC terminal facilities

9.      Covenas - negotiate with Cravo Norte to operate all Covenas facilities
except the existing DOL terminal facilities

Realizing  that not all of these assets are or will be JSC assets, the Parties
agreed to provide active support in negotiating with ODC and Cravo Norte
suitable terms and conditions under which the JSC and Canadian Group will
assume  operational  responsibility  in order to ensure maximum efficiency and
like operational and environmental exposures.

extension,  indulgence,  or  other action or omission in respect of any of the
JSC's  obligations,  in each case whether or not the parties hereto shall have
had any notice or knowledge of any of the foregoing.

           (b)     The obligations of the Purchaser created by this Agreement,
and in particular the obligation to acquire Shares in exchange for cash
pursuant  to  Calls, are several, not joint and several with any other party.

a guarantor of the JSC or of any other Shareholder or liable to meet any

States  District  Court  for the Southern District of New York (the "Specified
Court")  with respect to the enforcement of the arbitration provisions of this

enforcement  of  any award thereunder.  Each of the parties hereto irrevocably
appoints  the  agent for service specified opposite its name in Section 5.1 as
its  authorized agent in the Borough of Manhattan in The City of New York upon
which process may be served in any related suit or proceeding, and agrees that
service of process upon such agent, and written notice of said service to such
party,  by the person serving the same to the address provided in Section 5.1,
shall  be deemed in every respect effective service of process upon such party
in  any such suit or proceeding.  Each of the parties hereto further agrees to
take  any  and all action as may be necessary to maintain such designation and
appointment  of  such  agent in full force and effect for the duration of this
Agreement.

      The obligation of a party in respect of any sum due from it to the other
party hereunder expressed in United States dollars, notwithstanding any
judgment in a currency other than United States dollars, shall not be
discharged until the first Business Day following receipt by such party of any
sum  adjudged  to  be  so due in such other currency on which (and only to the
extent that) such party may in accordance with normal banking procedures
purchase  United States dollars with such other currency; if the United States
dollars so purchased are less than the sum originally due to such party
hereunder, the other party agrees, as a separate obligation and
notwithstanding any such judgment, to indemnify such party against such dollar
shortfall.  If the United States dollars so purchased are greater than the sum
originally  due to such party hereunder, such party agrees to pay to the other
party  an  amount equal to the excess of the dollars so purchased over the sum
originally due to such party hereunder.  [Not to be inserted in Ecopetrol

consents to and waives any objection which it may now or hereafter have to the
laying  of  venue of any proceeding relating to enforcement of the arbitration
provisions of this Agreement brought in the Specified Court and further
irrevocably waives, to the fullest extent it may effectively do so, the
defense  of an inconvenient forum to the maintenance of any such proceeding in
the Specified Court.

          (b)  To the extent that the Purchaser or any of its revenues, assets
or  properties  shall  be entitled, with respect to any proceeding relating to
enforcement of the arbitration provisions of this Agreement at any time
brought against the Purchaser or any of its revenues, assets or properties, to
any  sovereign or other immunity from suit, from jurisdiction, from attachment
prior to judgment, from attachment in aid of execution of judgment, from
execution of a judgment or from any other legal or judicial process or remedy,
and  to  the extent that in any jurisdiction there shall be attributed such an
immunity, the Purchaser irrevocably agrees not to claim and irrevocably waives
such immunity to the fullest extent permitted by the laws of such jurisdiction
(including,  without  limitation, the Foreign Sovereign Immunities Act 1976 of
the  United  States)  [if Ecopetrol, insert- , except as provided under Article
684 of the Codigo de Procedimiento Civil of Colombia].

                                                TO OLEODUCTO CENTRAL AGREEMENT

                   FORM OF PERFORMANCE GUARANTEE AGREEMENT


          AGREEMENT, dated as of December 14, 1994, made by [name of
Guarantor]  (the  "Guarantor")  in favor of OLEODUCTO CENTRAL S.A., a sociedad
anonima existing under the laws of Colombia (the "JSC").


                                   RECITALS

WHEREAS:

          A.  [Name of party whose obligations are being guaranteed] (the
"Company") and the JSC are parties to a Subscription Agreement, dated as of
December 14, 1994 (as amended from time to time, the "Subscription
Agreement"),  entered  into pursuant to the Oleoducto Central Agreement, dated
as of the same date (as amended from time to time, the "Oleoducto Central
Agreement");

          B.  The Company is an Affiliate of the Guarantor; and

          C.  As an inducement to the JSC to enter into the Subscription
Agreement,  the  Guarantor has agreed to enter into this Performance Guarantee
Agreement (the "Agreement").

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants  herein contained and for other good and valuable consideration (the
receipt  and  sufficiency  of which is hereby acknowledged), the Guarantor and
the JSC agree as follows:

          Section 1.  Definitions.  All capitalized terms used and not defined
herein have the meanings assigned to them in the Subscription Agreement.

          Section 2.  Representations and Warranties.  The Guarantor
represents and warrants to the JSC that:

            (a)  it is a corporation duly incorporated and organized under the
laws of its jurisdiction of incorporation;

          (b)  it has the requisite power and authority to enter into and
perform  its  obligations under this Agreement, and this Agreement constitutes
the valid and legally binding agreement of the Guarantor;

      (c)  the execution and delivery of, and the performance by the Guarantor
of  its  obligations  under,  this Agreement will not result in a breach of or
constitute a default under:

<PAGE>
               (i)  any provision of its corporate charter or articles of
                    incorporation or its by-laws;

         (ii)  any agreement or instrument to which it is a party and which is
material to the performance of its obligations hereunder; or

      (iii)  any order, judgment or decree of any court or governmental agency
to which it is a party or by which it is bound; and
      (d)  all of the outstanding capital stock of the Company (except for any
directors'  qualifying shares) is directly or indirectly beneficially owned by
the  Guarantor  [not applicable to Triton and TOTAL -- or by the same ultimate
parent  entity of the Company and the Guarantor], free and clear of all liens,
encumbrances, equities and claims.

          Section 3.  Performance Guarantee.  Subject to the provisions
contained herein, the Guarantor hereby irrevocably and unconditionally
guarantees to the JSC the full and punctual performance of all of the
Company's  obligations  (the  "Guaranteed Obligations") under the Subscription
Agreement.  In the event that the Company shall default in the full and timely
performance of any of the Guaranteed Obligations for any reason, the Guarantor
hereby  agrees  to  perform,  or to cause to be performed, any such Guaranteed
Obligations  fully and timely in accordance with the terms of the Subscription
Agreement.

            Section 4.  Unconditional Obligations of Guarantor.  The Guarantor
hereby agrees that its obligations hereunder are in the nature of a continuing
performance guarantee and shall remain valid and in full force irrespective of
any circumstances which might otherwise constitute a legal or equitable
discharge  of  a guarantor, including the absence of any action to enforce the
Subscription  Agreement  or any judgment against the Company; provided that it
is hereby acknowledged and agreed that (a) the Guarantor shall not be
obligated  under  this Agreement to make any payment in respect of any amounts
that  would  not be due under the Subscription Agreement were it to be a party
to  the  Subscription Agreement in the place and stead of the Company, (b) the
benefit  of  any  waiver or indulgence granted to, or any compromise with, the
Company  shall extend to the Guarantor and (c) in no event shall the Guarantor
be  obligated  to make payments hereunder exceeding in the aggregate the lower
of  (i)  U.S.$____ million and (ii) the Company's Shareholding Interest of the
Aggregate Subscription Obligation (or, in each case, the equivalent thereof in
Colombian pesos determined with respect to each payment hereunder by reference
to exchange rates between dollars and pesos in effect at the time of such
payment  based  on such rates available to the JSC as reasonably determined by
the  JSC),  less  in  each case all amounts (similarly determined) paid by the
Company pursuant to the Guaranteed Obligations.

          Section 5.  No Waiver.  No failure on the part of the JSC to
exercise,  and  no  delay  in exercising, any right, remedy or power hereunder
shall operate as a waiver thereof, nor shall any single or particular exercise
by the JSC of any right, remedy or power hereunder preclude any other or
future exercise of any other right, remedy or power.

<PAGE>
            Section 6.  Subrogation.  The Guarantor shall be subrogated to all
rights  of  the  JSC against the Company in respect of any amounts paid by the
Guarantor  pursuant  to  the  provisions of this Agreement; provided, however,
that the Guarantor shall not be entitled to enforce, or to receive any
payments  arising out of or based upon, such right of subrogation until all of
the  Guaranteed  Obligations  under the Subscription Agreement shall have been
performed  in  full,  all the Senior Debt referred to in the Oleoducto Central
Agreement provided by the Senior Lender Group for whose benefit the
Subscription Agreement may be assigned by the JSC has been repaid and all
other obligations of the Company owed to the JSC have been discharged in full.

            Section 7.  Effectiveness.  This Agreement shall have no effect or
validity unless and until the Subscription Agreement shall have become
effective and performance guarantee agreements in substantially identical form
to this Agreement with Affiliates of the other Shareholders (except Ecopetrol)
shall have become effective.

          Section 8.  Termination.  This Agreement shall terminate on the
earlier of (a) the complete performance or termination of all Guaranteed
Obligations  of  the  Company under the Subscription Agreement and (b) July 1,
2002.

           Section 9.  Successors.  This Agreement may only be assigned by the
JSC in connection with an assignment of the Subscription Agreement to a
permitted assignee under Section 5.3 thereof.  The obligations of the
Guarantor hereunder shall be binding upon the Guarantor and its successors and
assigns  and  shall  inure to the benefit of and be enforceable by the JSC and
any of its successors and assigns.

           Section 10.  Release.  (a)  The Guarantor shall not be released and
discharged from any of its obligations hereunder except to the extent that, in
connection  with  the  simultaneous  transfer of all or any part of the Shares
held by the Company to a Person that is a permitted transferee thereof
pursuant  to  Article  Ten  of the Oleoducto Central Agreement, such permitted
transferee assumes or undertakes the related obligations under the
Subscription  Agreement or such obligations are guaranteed under a performance
guarantee agreement in substantially identical form to this Agreement as
provided therein.

          (b)  Notwithstanding the foregoing, the Guarantor shall not be
released  or  discharged from obligations which shall have been incurred prior
to the release and discharge referred to in paragraph (a) of this Section 10.

action, suit or proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby (a "Related Proceeding").  The Guarantor

force and effect for the duration of this Agreement.

          The obligation of the Guarantor in respect of any sum due from it to
the  JSC expressed in United States dollars, notwithstanding any judgment in a
currency  other  than United States dollars, shall not be discharged until the
first  Business  Day following receipt by the JSC of any sum adjudged to be so
due  in such other currency on which (and only to the extent that) the JSC may
in  accordance  with  normal banking procedures purchase United States dollars
with  such other currency.  If the United States dollars so purchased are less
than  the  sum originally due to the JSC hereunder, the Guarantor agrees, as a
separate  obligation  and  notwithstanding any such judgment, to indemnify the
JSC  against such dollar shortfall.  If the United States dollars so purchased
are  greater  than the sum originally due to the JSC hereunder, the JSC agrees
to pay to the Guarantor an amount equal to the excess of the dollars so
purchased over the sum originally due to the JSC hereunder.

          Section 15.  Headings.  The headings contained herein are for
convenience of reference only and do not constitute a part of this Agreement.

                          POLITICAL EVENTS AGREEMENT


          AGREEMENT, dated as of the 14th day of December, 1994, among:

            OLEODUCTO CENTRAL S.A., a sociedad anonima existing under the laws
of Colombia;

          EMPRESA COLOMBIANA DE PETROLEOS - ECOPETROL, an Empresa Industrial y
Comercial  del  Estado existing under the laws of Colombia and wholly owned by
Colombia;

          BP COLOMBIA PIPELINES LIMITED, a corporation existing under the laws
of England and Wales;

           TOTAL PIPELINE COLOMBIE S.A., a corporation existing under the laws
of France;

              TRITON PIPELINE COLOMBIA, INC., a corporation existing under the
laws of the Cayman Islands;

             IPL ENTERPRISES (COLOMBIA) INC., a corporation existing under the
laws of the Cayman Islands; and

             TCPL INTERNATIONAL INVESTMENTS INC., a corporation existing under
the laws of Alberta, Canada.


                                   RECITALS

WHEREAS:


           A.     The Shareholders have formed the JSC by public deed no.
of December 14, 1994 granted before notary public no. 38 of Santafe de Bogota;

              B.     The Shareholders have entered into the  Oleoducto Central
Agreement  (as  amended  from  time to time, the Oleoducto Central Agreement),
dated  as of December 14, 1994, among the JSC and the Shareholders (as defined
therein) specifying certain terms and conditions of their respective
investments and participation in the JSC, the Oleoducto Central and the
financing and operation thereof.


<PAGE>
          C.     The Oleoducto Central Agreement contemplates that the
financing of the Oleoducto Central will be comprised of approximately 30%
Equity  Contributions  and approximately 70% Senior Debt raised by the JSC and
provided by four separate Senior Lender Groups. Under Sections 5.2(e) and
5.3(b)(i)  and  (ii)  of the Oleoducto Central Agreement, except to the extent
otherwise provided in this Agreement, a failure by a Shareholder to make
timely  Equity  Contributions or the existence of a Senior Debt Shortfall with
respect  to the Initial Shipper Group of which a Shareholder is a member could
result  in  certain  adverse consequences, including an increase in the tariff
payable  by  the  Initial  Shipper in such Initial Shipper Group for Petroleum
shipped by or on its behalf under its Transportation Agreement (Sections
5.2(e) and 5.3(b)(i) and (ii) being referred to herein as the "OCA Remedies").

            D.     The parties wish to provide in this Agreement the terms and
conditions  under  which, upon the occurrence of certain Political Events, one
or  more  Shareholders may suspend (subject to reinstatement) or terminate its
obligations to make Equity Contributions on a timely basis, including to
purchase  Shares  under  its Subscription Agreement (the "Purchase Obligations")
and the application to it and its Affiliates of the OCA Remedies.

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants  herein contained and for other good and valuable consideration (the
receipt and sufficiency of which is hereby acknowledged), the parties agree as
follows:

                                 ARTICLE TWO

                     JOINT DECLARATION OF POLITICAL EVENT

           Section 2.1.       Joint Declaration.  A declaration of a Political
Event  shall  be  effective  only upon the receipt by the JSC of a certificate
signed by each Shareholder that is a member of an Initial Shipper Group (other
than  Ecopetrol  and  any Shareholder that is precluded under Section 5.1 from
declaring a Political Event) to the effect that such Political Event has
occurred  and is continuing as of the date of such certificate; provided that,
in case of clauses (b) and (d) of the definition of Political Violence,
execution by a Shareholder that is not also an Affiliate of an Initial Shipper
shall  not be required.  Such certificate shall set forth in reasonable detail
(a)  the  events, conditions, circumstances or occurrences that constitute the
Political Event, (b) the type of Political Event that has occurred and is
continuing, (c) the date as of which such Political Event has occurred and (d)
a statement to the effect that the restrictions under Section 5.1 on the right
to  declare  a  Political Event do not apply.  Any one of the Shareholders not
executing  such  certificate shall have the right to object to the declaration
of a Political Event under this Section by calling for arbitration under
Section 6.1 within 60 days of the effectiveness of the Political Event
declaration.    The  declaration of the Political Event shall remain effective
pending  resolution of the arbitration proceeding.  This Article Two shall not
apply to declarations of Political Events under Section 3.1 or Section 4.1.

          Section 2.2.  Suspension of Purchase Obligations and of OCA
Remedies.  Upon a joint declaration in accordance with Section 2.1, the
Purchase Obligations of all Shareholders and the application to such
Shareholders of the OCA Remedies shall be suspended.

             Section 2.3.       Termination of Purchase Obligations and of OCA
Remedies.    (a)  The Purchase Obligation of a Shareholder and the application
to  it  of  the OCA Remedies shall terminate if a suspension under Section 2.2
continues for 365 days without reinstatement; provided that, if an arbitration
proceeding  is  commenced,  and  the arbitrators rule against the Shareholders
which executed the certificate under Section 2.1, such 365-day period shall be
extended by the number of days that expire between the date on which the
corresponding  notice  demanding arbitration is delivered by a Shareholder not
delivering a notice under Section 2.1 and the arbitrators issue their ruling.

<PAGE>
          (b)  In case of termination under clause (a), the Subscription
Agreement  of  the terminated Shareholder shall terminate (subject to survival
of certain provisions as provided therein) and the Performance Guarantee
Agreement of any Affiliate shall terminate (other than to the extent of
survival  of  certain  provisions of the corresponding Subscription Agreement)
and  (b) the terminated Shareholder shall cease to be a party to the Oleoducto
Central Agreement (subject to survival of certain provisions as provided
therein).

              Section 2.4.       Reinstatement.  Reinstatement for purposes of
this Article Two shall occur upon the occurrence, prior to termination, of any
of the following events:

     (a)  Any Shareholder objects to the joint declaration of Political Event,
commences  arbitration  proceedings within 60 days of the effectiveness of the
Political  Event declaration and the arbitrators rule that the Political Event
claimed  in  the  certificate delivered under Section 2.1 did not occur or was
not  continuing as of the date of the certificate, or that the restrictions in
Section 5.1 applied;

     (b)  One or more of the Shareholders which executed the certificate under
Section 2.1 delivers a certificate to the JSC, with copies to the other
Shareholders,  to  the  effect  that the Political Event that gave rise to the
suspension has ceased (provided that the other Shareholders which executed the
certificate under Section 2.1 can object to, and within 60 days of the
delivery  of the cessation certificate commence arbitration on, the claim that
the  Political  Event  has ceased, in which case the reinstatement certificate
will  be  effective  as to the objecting Shareholders only if arbitrators rule
that the Political Event had ceased as of the date of the reinstatement
certificate); or

       (c)  Any Shareholder which executed the certificate pursuant to Section
2.1  fails to deliver a reinstatement certificate under clause (b) upon demand
of  another Shareholder, the other Shareholders commence arbitration within 60
days  of  demanding  that  the suspending Shareholders deliver a reinstatement
certificate on the ground that the Political Event has ceased, and the
arbitrators rule that the Political Event that gave rise to the suspension had
ceased as of the time of the demand for a reinstatement certificate.

The  Purchase  Obligations  of  reinstated Shareholders will apply immediately
upon  reinstatement  as  if no suspension had occurred.  The OCA Remedies will
apply retroactively to failures to make Equity Contributions or to Senior Debt
Shortfalls  during  the  suspension  period if and to the extent that prior to
reinstatement other Shareholders have not purchased Shares in lieu of the
reinstated  Shareholder  and the JSC otherwise has not covered the Senior Debt
Shortfall created during the suspension and within 15 days following
reinstatement the shortfall in Equity Contributions or the Senior Debt
Shortfall,  as the case may be, continue; provided that in case of retroactive
application  the Transportation Agreement Step-Up shall continue to apply only
until  the date the Equity Contribution shortfall or Senior Debt Shortfall, as
the case may be, is made up, rather than (as is contemplated in the definition
of  the  Transportation  Agreement  Step-up set forth in the Oleoducto Central
Agreement) for one year after such date.

<PAGE>
          Section 2.5.       Canadian Group.  In the event of suspension under
this Article of the Purchase Obligations of the members of the Canadian Group,
the application to them of the remedies under Section 5.3(b)(iii) of the
Oleoducto  Central  Agreement  shall  continue, although during the suspending
period the JSC shall not exercise its right to terminate the Oleoducto Central
Operations  Agreement.  Following the earlier of termination or reinstatement,
there will be no restriction on the JSC's right to exercise all remedies under
such Section 5.3(b)(iii) during and for the periods indicated therein;
provided  that,  in the case of reinstatement, the JSC shall be obliged to (a)
cease to exercise the right to cancel partially or entirely payment of
operating, incentive and other fees payable under the Oleoducto Central
Operations Agreement and (b) not exercise its right to terminate the Oleoducto
Central Operations Agreement, in each case as a result of Equity Contributions
not  made  by the reinstated Shareholder during the suspension period, if (but
only  if)  within 15 days of reinstatement the reinstated Shareholder makes up
in full any Equity Contributions it failed to make during the suspending
period which were not otherwise made up by other Shareholders during such
period.

                                ARTICLE THREE

                  UNILATERAL DECLARATION OF POLITICAL EVENT

           Section 3.1.       Unilateral Declaration.  If an event of the type
identified in clause (a) or (b) of the definition of Expropriatory Action
occurs and is continuing (other than as a result of the imposition of
confiscatory  taxation or imposition of confiscatory charges), any Shareholder
as  to which such Expropriatory Action relates  that is a member of an Initial
Shipper Group (other than Ecopetrol and any Shareholder that is precluded
under  Section  5.1  from declaring a Political Event) shall have the right to
declare  a Political Event by delivering a certificate to the JSC, with a copy
to  each  other  Shareholder, to the effect that such Expropriatory Action has
occurred and is continuing as of the date of such certificate.  Such
certificate  shall  set forth in reasonable detail (a) the events, conditions,
circumstances or occurrences that constitute the Expropriatory Action, (b) the
date as of which such Expropriatory Action has occurred and (c) a statement to
the  effect  that the restrictions under Section 5.1 on the right to declare a
Political  Event  do not apply to it.  The JSC and any one of the Shareholders
not  delivering certificates shall have the right to object to the declaration
of a Political Event under this Section by calling for arbitration pursuant to
Section 6.1 within 60 days of receipt of the certificate declaring the
Political Event.  The declaration of the Political Event shall remain
effective  pending  resolution  of the arbitration proceeding.  Although joint
action is not required under this Section, more than one Shareholder can
declare a Political Event hereunder at the same time.

          Section 3.2.       Suspension of Purchase Obligation and of
Application  of  OCA  Remedies.  Upon a declaration in accordance with Section
3.1, the Purchase Obligation of the suspending Shareholder and the application
to it of the OCA Remedies shall be suspended.

<PAGE>
            Section 3.3.       Other Consequences of Unilateral Declaration of
Political  Event.  (a)  Escrow Account.  Upon a declaration in accordance with
Section 3.1, the suspending Shareholder shall execute an escrow agreement
substantially  in  the  form set forth in Schedule A (the "Escrow Agreement"),
with the New York office of a commercial bank selected by the declaring
Shareholder organized under the laws of the United States of America or of any
State thereof and having a combined capital and surplus of at least
U.S.$500,000,000  (the  "Escrow  Agent")  providing for the establishment of a
segregated  bank  account in New York (the "Escrow Account").  So long as such
Shareholder's  Purchase  Obligation remains suspended, it shall deposit in the
Escrow Account an amount equal to not less than 50% of the Equity
Contributions  that  it would have been obliged to make to the JSC but for the
suspension  of  its Purchase Obligation under Section 3.1. Such deposits shall
be  made  within  the time periods during which the Equity Contributions would
have  to be made but for the suspension.  The failure to enter into the Escrow
Agreement or to make a timely deposit under this clause shall result in
reinstatement  under  Section  3.5.  Funds held in the Escrow Account shall be
invested  and distributed as provided in the Escrow Agreement. Instructions on
distributions  shall be delivered to the Escrow Agent by the JSC in accordance
with Section 3.5(d) or by the terminated Shareholder in accordance with
Section  3.4(b)(iv),  and  shall  not be delivered by any other party hereto.
This clause shall not apply at any time during which the suspending
Shareholder's  Purchase Obligation also is suspended by application of Section
2.2.

            (b)  Performance Guarantee.  Upon a declaration in accordance with
Section 3.1, the suspending Shareholder shall deliver to the JSC and each
other  Shareholder a performance guarantee agreement substantially in the form
set forth in Schedule B (the "Political Event Performance Guarantee
Agreement"), executed by the party which is then guarantor under the
Performance  Guarantee  Agreement  that relates to its Subscription Agreement,
pursuant to which such guarantor will guarantee the obligations of the
suspending Shareholder under this Agreement.  The parties acknowledge that the
Political  Event  Performance  Guarantee  Agreement will contain an expiration
date and maximum coverage limitations.  The suspending Shareholder shall
deliver to the JSC a substitute Political Event Performance Guarantee
Agreement  prior to the earlier of (i) six months prior to the expiration date
of the Political Event Performance Guarantee Agreement then in effect and (ii)
the date on which the sum of aggregate accrued contingent liabilities and
actual payments under the Political Event Performance Guarantee Agreement then
in  effect  equal 85% of the maximum coverage limitation therein.  The failure
to  deliver  the executed Political Event Performance Guarantee Agreement or a
substitute therefor as provided in the preceding sentence shall result in
reinstatement under Section 3.5.

          (c)  Other Shareholders' Option to Fund.  So long as a Shareholder's
Purchase Obligation is suspended under Section 3.2, each of the other
Shareholders (other than a Shareholder the Purchase Obligations of which shall
then  be  suspended  or terminated under this Agreement) shall have the right,
but  not the obligation, on its own behalf or, if more than one Shareholder so
elects, jointly with such other Shareholder(s), pro rata to their Shareholding
Interests, to make Equity Contributions not made by the suspended Shareholder.
 To the extent one or more Shareholders exercise this option, the suspended

<PAGE>
Shareholder  shall  pay to each such Shareholder a percentage of the amount of
the  Equity  Contributions  made  by such Shareholder in lieu of the suspended
Shareholder,  which percentage shall be calculated (based on the actual number
of days elapsed between the date an Equity Contribution is made in lieu of the
suspending Shareholder and the date the obligation to pay this amount
terminates)  at a rate per annum equal to the Benchmark Interest Expense, such
amount  being  payable  in  arrears on the first Business Day of each calendar
month until the first calendar month that follows termination pursuant to
Section  3.5  or  reinstatement  pursuant to Section 3.5 (for purposes of this
clause,  the  "payment  amounts"  and the "payment period"); provided that, in
case the funding Shareholder shall receive any Distribution as a result of the
application of the proviso in Section 5.3(e) of the Oleoducto Central
Agreement at any time during the payment period, the amount of the
Distribution received shall be credited against future payment amounts payable
by the non-funding Shareholder; and provided further that after termination of
the  payment  period,  the funding Shareholder shall reimburse the non-funding
Shareholder (subject, if applicable, to set-off against the put purchase price
payable to the funding Shareholder under Section 3.5(e) hereof) for any
payment  amounts  received  and  not previously credited against Distributions
that  have  not been previously credited against payment amounts.  This clause
shall not apply at any time during which the suspending Shareholder's Purchase
Obligation also is suspended by application of Section 2.2.

          Section 3.4.       Termination of Purchase Obligations and of
Application of OCA Remedies.  (a) The Purchase Obligation of a declaring
Shareholder  and  the  application  to it of OCA Remedies shall terminate if a
suspension  under  Section  3.2  continues for 365 days without reinstatement;
provided  that, if an arbitration proceeding is commenced, and the arbitrators
rule against the suspending Shareholder, such 365-day period shall be extended
by  the number of days that expire between the date on which the corresponding
notice of arbitration is delivered and the arbitrators issue their ruling.

          (b)  In case of a termination under clause (a):

              (i)     the Subscription Agreement of the terminated Shareholder
shall terminate (subject to survival of certain provisions in the Subscription
Agreement as provided therein);

             (ii)  the Performance Guarantee Agreement of any Affiliate of the
terminated  Shareholder  shall terminate (other than to the extent of survival
of certain provisions of the corresponding Subscription Agreement);

            (iii)  the terminated Shareholder shall cease to be a party to the
Oleoducto Central Agreement (subject to survival of certain provisions as
provided therein);

     (iv)  the terminated Shareholder shall have the right to deliver an
instruction  under Section 4 of the Escrow Agreement to the Escrow Agent, with
a  copy to the JSC and the other Shareholders, instructing the Escrow Agent to
deliver to the terminated Shareholder all funds on deposit in the Escrow
Account;

<PAGE>
            (v)  the JSC shall exercise the right it has in the Transportation
Agreement of the Initial Shipper that is a member of such terminated
Shareholder's Initial Shipper Group to apply as to future shipments of
Petroleum by such Initial Shipper or on its behalf a tariff that is the higher
of  the  Initial  Shipper Tariff and the Third Party Shipper Tariff applicable
from  time to time; provided that the JSC shall not exercise such right to the
proportion  of  the  Petroleum shipped by or on behalf of such Initial Shipper
that is equal to the proportion that the Equity Contributions made by the
terminated Shareholder prior to the suspension and termination of its
obligations  under  this  Article bears to the total Equity Contributions that
would  have  been required from the terminated Shareholder prior to Completion
(but  for  suspension and termination under this Agreement) in the most recent
Financing Plan adopted by the Board of Directors of the JSC.  This clause
shall  cease  to apply if and when the obligations of the Shareholders to make
Equity Contributions are terminated pursuant to Section 2.4.

          Section 3.5.       Reinstatement.  (a) Reinstatement Events.
Reinstatement for purposes of this Article Three shall occur upon the
occurrence, prior to termination, of any of the following events:

          (i)  the JSC or any other Shareholder objects to the unilateral
declaration  of  Political  Event, commences arbitration proceedings within 60
days of receipt of the certificate declaring the Political Event, and the
arbitrators rule that the Political Event claimed in the certificate delivered
under  Section  3.1  did not occur or was not continuing as of the date of the
certificate, or that the restrictions in Section 5.1 applied;

          (ii)  the suspended Shareholder delivers a reinstatement certificate
to the JSC to the effect that the Political Event that gave rise to the
suspension has ceased;

             (iii)  the suspended Shareholder fails to deliver a reinstatement
certificate  under  (ii) above upon demand of the JSC or any other Shareholder
on the grounds that the Political Event has ceased, the objecting party
commences arbitration within 60 days of demanding that the suspended
Shareholder deliver a reinstatement certificate, and the arbitrators rule that
the Political Event that gave rise to the suspension had ceased as of the time
of the demand for a reinstatement certificate;

            (iv)  the suspended Shareholder fails to enter into or maintain in
effect  the  Escrow  Agreement or fails to make on a timely basis the deposits
into the Escrow Account contemplated by Section 3.3(a); or

           (v)  the suspended Shareholder fails to deliver to the JSC and each
other Shareholder or to maintain in effect the executed Political Event
Performance Guarantee Agreement (whether because of expiration, limitations on
coverage  resulting from accrued contingent obligations or actual payments, or
otherwise).

          (b)  Purchase Obligation.  Upon reinstatement the Purchase
Obligation of the reinstated Shareholder will apply immediately as if no
suspension had occurred.

<PAGE>
           (c)  OCA Remedies.  Upon reinstatement, the OCA Remedies will apply
retroactively  to  the  reinstated Shareholder as if such suspension had never
occurred  to  failures  to meet Purchase Obligations or Senior Debt Shortfalls
during  the suspension period if and to the extent that prior to reinstatement
other Shareholders have not made Equity Contributions in lieu of the
reinstated  Shareholder  and the JSC otherwise has not covered the Senior Debt
Shortfall created during the suspension and within 15 days following
reinstatement the shortfall in Equity Contributions or the Senior Debt
Shortfall, as the case may be, continues; provided that in case of retroactive
application  the Transportation Agreement Step-Up shall continue to apply only
until  the  date the Equity Contribution or Senior Debt Shortfall, as the case
may  be,  is made up, rather than (as is contemplated in the definition of the
Transportation Agreement Step-up) for one year after such date.

           (d)  Escrow Account.  Within ten Business Days after the earlier of
the  date  on which each Shareholder having a put right under clause (e) shall
have  exercised  and  the  expiration of the 30-day period referred to in such
clause,  the  JSC  shall  deliver an instruction under Section 4 of the Escrow
Agreement,  with  a  copy to each Shareholder, instructing the Escrow Agent to
deliver  promptly, but in any case within two Business Days of delivery of the
instruction, all funds on deposit in the Escrow Account to the following
Persons in the following order of priority:

               (i)  to the extent put rights are exercised, to the sellers (as
defined in clause (e)) in or towards satisfaction of the purchase price
payable by the purchaser under such clause pro rata among the sellers based on
the number of Shares being sold;

          (ii)  to the JSC in satisfaction of any outstanding Purchase
Obligation  of the reinstated Shareholder not met by other Shareholders during
the suspension period; and

          (iii)  the balance, if any, to the reinstated Shareholder.

          (e)  Put Right.  Upon reinstatement under clause (a), each
Shareholder (for purposes of this clause, the "seller") which shall have
exercised  the  option pursuant to Section 3.3(c) to make Equity Contributions
in lieu of the suspending Shareholder shall have the right to require the
reinstated Shareholder (for purposes of this clause, the "purchaser") to
purchase  all  or  a portion of the Shares and other securities or instruments
(together,  for  purposes  of this clause, the "Put Securities") issued to the
seller or on its behalf  by the JSC in connection with such Equity
Contributions  by  giving the purchaser notice no later than 30 days following
the date on which reinstatement occurs, specifying the number of Put
Securities  to  be  purchased. The purchase price per Put Security shall equal
the sum of (i) the amount of the Equity Contributions made for such Put
Security  and  (ii)  an  amount calculated (based on the actual number of days
elapsed between the date such Put Security was purchased in lieu of the
purchaser  and  the last day of the calendar month preceding the date on which
the  seller  notifies  the  purchase that it is exercising the put right) at a
rate  of  13.5% per annum of the amount in (i), less any Distribution received
in respect

<PAGE>
of such Put Security as of such calculation date.  The closing on the purchase
shall  occur  on  the later of (A) ten Business Days after the date the seller
notifies  the  purchaser that it is exercising its put right and (B) the first
Business  Day  following the receipt of any necessary governmental approvals.
Clause  (d)  contemplates  that funds in the Escrow Account will be applied in
the first instance to pay to each seller, pro rata based on the aggregate
purchase price payable to such seller, such purchase price.



                                 ARTICLE FOUR

               DECLARATION OF POLITICAL EVENT BY CANADIAN GROUP

             Section 4.1.       Declaration by Canadian Group.  If an event of
the  type  identified  in clause (a) of the definition of Expropriatory Action
occurs and is continuing (other than as a result of the imposition of
confiscatory  taxation  or imposition of confiscatory charges), the members of
the  Canadian  Group,  acting  jointly, shall have the right (unless precluded
under  Section  5.1)  to  declare a Political Event by delivering to the JSC a
certificate  executed  by both of them, with a copy to each other Shareholder,
to the effect that such Expropriatory Action has occurred and is continuing as
of the date of such certificate.  Such certificate shall set forth in
reasonable  detail  (a)  the  events, conditions, circumstances or occurrences
that constitute the Expropriatory Action, (b) the date as of which such
Expropriatory  Action  has occurred and (c) a statement to the effect that the
restrictions  under  Section  5.1 on the right to declare a Political Event do
not apply to it.  The JSC or any of the Shareholders not delivering
certificates  shall have the right to object to the declaration of a Political
Event  by calling for arbitration within 60 days of receipt of the certificate
declaring  the  Political Event.  The declaration of the Political Event shall
remain effective pending resolution of the arbitration proceeding.

          Section 4.2.       Suspension of Purchase Obligations.  Upon a
declaration  in  accordance  with Section 4.1, the Purchase Obligations of the
members  of the Canadian Group shall be suspended.  In the event of suspension
of  the  Purchase  Obligations,  the application to them of the remedies under
Section 5.3(b)(iii) of the Oleoducto Central Agreement shall continue,
although  during the suspension period the JSC shall not exercise its right to
terminate the Oleoducto Central Operations Agreement.

             Section 4.3.       Other Consequences of Declaration of Political
Event by Canadian Group. (a) Escrow Account.  Upon a declaration in accordance
with  Section  4.1,  each member of the Canadian Group shall execute an Escrow
Agreement  with an Escrow Agent selected by it providing for the establishment
of an Escrow Account.  So long as such Shareholders' Purchase Obligation
remains  suspended,  it shall deposit in the Escrow Account an amount equal to
not  less than 50% of the Equity Contributions that it would have been obliged
to  make  to the JSC but for the suspension of its Purchase Obligations.  Such
deposits shall be made within the time periods during which the Equity
Contributions  would  have  to  be made but for the suspension. The failure to
enter into the Escrow

<PAGE>
Agreement or to make a timely deposit under this clause shall result in
reinstatement  under  Section  4.5.  Funds held in the Escrow Account shall be
invested  and  withdrawn as provided in the Escrow Agreement.  Instructions on
distributions shall be delivered to the Escrow Agent only by the JSC in
accordance  with Section 3.5(d) or by the terminated Shareholder in accordance
with Section 4.4(b)(iv) and shall not be delivered by any other party hereto.
This clause (c) shall not apply at any time during which the Purchase
Obligations  of such Shareholders also are suspended by application of Section
2.2.

            (b)  Performance Guarantee.  Upon a declaration in accordance with
Section  4.1,  each  of the members of the Canadian Group shall deliver to the
JSC and each other Shareholder a Political Event Performance Guarantee
Agreement  executed by the party which is then guarantor under the Performance
Guarantee  Agreement  that relates to its Subscription Agreements, pursuant to
which  such guarantor will guarantee the obligations of such Shareholder under
this  Agreement.  The parties acknowledge that the Political Event Performance
Guarantee Agreement will contain an expiration date and maximum coverage
limitations.  The suspending Shareholder shall deliver to the JSC a substitute
Political  Event  Performance  Guarantee Agreement prior to the earlier of (i)
six  months  prior  to  the expiration date of the Political Event Performance
Guarantee Agreement then in effect and (ii) the date on which the sum of
aggregate accrued contingent liabilities and actual payments under the
Political  Event  Performance  Guarantee Agreement then in effect equal 85% of
the  maximum  coverage  limitation therein.  The failure to deliver executed a
Political  Event  Performance  Guarantee Agreement or a substitute therefor as
provided in the preceding sentence shall result in reinstatement under Section
4.5.

             (c)  Other Shareholders' Option to Fund.  So long as the Purchase
Obligations  of  the  members of the Canadian Group is suspended under Section
4.2,  each  of  the  other Shareholders (other than a Shareholder the Purchase
Obligations of which shall then be suspended or terminated under this
Agreement) shall have the right, but not the obligation, on its own behalf or,
if more than one Shareholder so elects, jointly with such other
Shareholder(s), pro rata to their Shareholding Interests, to make Equity
Contributions  not  made  by  the suspended Shareholder.  To the extent one or
more Shareholders exercise this option, the suspended Shareholder shall pay to
each  such Shareholder, a percentage of the amount of the Equity Contributions
made by such Shareholder in lieu of the suspended Shareholders, which
percentage  shall  be  calculated  (based on the actual number of days elapsed
between the date an Equity Contribution is made in lieu of the suspended
Shareholders  and  the date the obligation to pay this amount terminates) at a
rate per annum equal to the Benchmark Interest Expense such amounts being
payable in arrears on the first Business Day of each calendar month until such
amounts  shall  cease  to  be paid commencing on the first calendar month that
follows termination pursuant to Section 4.4 or reinstatement pursuant to
Section 4.5 (for purposes of this clause, the "payment amounts" and the
"payment period"); provided that, in case the funding Shareholder shall
receive any Distribution as a result of the application of the proviso in
Section 5.3(e) of the Oleoducto Central Agreement at any time during the
payment period, the amount of the Distribution received shall be credited
against future payment amounts payable by the non-funding

<PAGE>
Shareholder; and provided further that after termination of the payment
period,  the  funding  Shareholder shall reimburse the non-funding Shareholder
(subject,  if applicable, to set-off against the put purchase price payable to
the  funding  Shareholder under Section 3.5(e) hereof) for any payment amounts
received  and not previously credited against Distributions that have not been
previously  credited  against payment amounts.  This clause shall not apply at
any  time during which the Purchase Obligations of the members of the Canadian

             Section 4.4.       Termination of Purchase Obligations.  (a)  The
Purchase  Obligation  of  a  member of the Canadian Group shall terminate if a
suspension under Section 4.2 continues for 365 days without reinstatement
pursuant to Section 4.5; provided that, if an arbitration proceeding is
commenced, and the arbitrators rule against the members of the Canadian Group,
such 365-day period shall be extended by the number of days that expire
between the date on which the corresponding notice of arbitration is delivered
and the arbitrators issue their ruling.

          (b)  In case of a termination under clause (a):

             (i)     the Subscription Agreements of the terminated Shareholder
shall terminate (subject to survival of certain provisions in the Subscription

right to exercise all remedies under Section 5.3(b)(iii) of the Oleoducto
Central Agreement during and for the periods indicated therein.

             (ii)  the Performance Guarantee Agreement of any Affiliate of the
terminated  Shareholder  shall terminate (other than to the extent survival of
certain provisions of the corresponding Subscription Agreement);

            (iii)  the terminated Shareholder shall cease to be a party to the
Oleoducto Central Agreement (subject to survival of certain provisions as
provided therein); and

           (iv)  the terminated Shareholder shall have the right to deliver an
instruction  under Section 4 of the Escrow Agreement to the Escrow Agent, with

Political  Event  by  the members of the Canadian Group, commences arbitration
proceedings  within  60 days of receipt of the certificate declaring the Event
of  Default,  and the arbitrators rule that the Political Event claimed in the
Section 4.1 certificates did not occur or was not continuing as of the date of
the certificate delivered under Section 4.1, or that the restrictions in
Section 5.1 applied;

<PAGE>
          (ii)  either member of the Canadian Group delivers to the JSC a
certificate  executed  by  it to the effect that the Political Event that gave
rise to the suspension has ceased (provided that the other member of the
Canadian Group can object to, and within 60 days of the delivery of the
cessation  certificate  commence  arbitration on, the claim that the Political
Event has ceased, in which case the reinstatement certificate will be
effective  as  to  the objecting Shareholder only if arbitrators rule that the
Political Event had ceased as of the date of the reinstatement certificate);

          (iii)  the members of the Canadian Group fail to deliver a
reinstatement certificate under (ii) above upon demand of the JSC or any other
Shareholder  on the grounds that the Political Event has ceased, the objecting
party  commences  within 60 days of demanding that the members of the Canadian
Group  deliver  a reinstatement certificate, and the arbitrators rule that the
Political  Event that gave rise to the suspension had ceased as of the time of
the demand for a reinstatement certificate;

             (iv)  as to either member of the Canadian Group, such Shareholder
fails  to  enter  into  or maintain in effect the Escrow Agreement or fails to
make  on  a  timely basis the deposits into the Escrow Account contemplated by
Section 4.3(a); or

              (v)  as to either member of the Canadian Group, such Shareholder
fails to deliver to the JSC and each other Shareholder or to maintain in

expiration, limitations on coverage resulting from accrued contingent
obligations or actual payments, or otherwise).

          (b)  Purchase Obligations; Application of Section 5.3(b)(iii).  Upon
reinstatement under clause (a), the Purchase Obligations of the members of the
Canadian Group will apply immediately as if no suspension had occurred.

exercise the right to cancel partially or entirely payment of operating,
incentive and other fees payable under the Oleoducto Central Operations
Agreement  and  (ii) not exercise its right to terminate the Oleoducto Central
Operations  Agreement,  in  each  case as a result of Equity Contributions not
made  by the reinstated Shareholder during the suspension period, if (but only
if)  within  15  days  of reinstatement the reinstated Shareholder makes up in
full  any  Equity Contributions it failed to make during the suspension period
which were not otherwise made up by other Shareholders during such period.

           (c)  Escrow Account.  Within ten Business Days after the earlier of

towards satisfaction of the purchase price payable by the purchaser under such
clause pro rata among the sellers based on the number of Shares being sold;

          (ii)  to the JSC in satisfaction of any outstanding Purchase
Obligation  of  the reinstated Shareholder to purchase Shares not purchased by
other Shareholders during the suspension period; and

          (iii)  the balance, if any, to the reinstated Shareholder.

          (d)  Put Right.  Upon reinstatement under clause (a), each

          Section 5.1.       Restrictions on Rights to Declare Political
Events.  Notwithstanding any other provision of this Agreement, no Shareholder
shall  have  a right to declare a Political Event pursuant to Section 2.1, 3.1
or 4.1 if:

     (a)  the failure of such party (or any of its Affiliates, as the case may
be) or, in the case of Section 2.1, the JSC to comply in any material respects
with  its  respective  obligations under (i) any binding agreement freely made
between any of them and Colombia or a governing authority which is in de facto
control of part of Colombia or (ii) any law, statute, decree, writ or order of
Colombia  or any governmental authority thereof binding on it (other than such
law,  statute,  decree, writ or order, the adoption or application of which to
the Oleoducto Central would

<PAGE>
 constitute Expropriatory Action) is the principal, direct and proximate cause
of such Political Event;

     (b)  the events, conditions or occurrences which constitute such
Political  Event have been voluntarily agreed to (which for this purpose shall
not include coerced agreement), or have been voluntarily arranged or
deliberately  instigated, by such party (or any of its Affiliates, as the case
may be) or, in the case of Section 2.1, the JSC;

     (c)  such party (or any of its Affiliates, as the case may be) or, in the
case of Section 2.1, the JSC has failed to take reasonable precautions or
pursue reasonable alternative measures available to it to prevent, or to
mitigate the effects of, the occurrence or continuation of such Political
Event;  provided, however, that neither such party (nor any of its Affiliates)
nor,  in the case of Section 2.1, the JSC shall be required by this clause (c)
to  accept,  acquiesce  in or agree to any modification of any right, make any
payment  or  concession  it is not legally obligated to make or enter into any
settlement,  compromise  or  agreement  with any governmental authority, labor
union or other person that it is not legally obligated to enter into; or

     (d)  in the case of Expropriatory Action, such party (or any of its
Affiliates,  as  the  case may be) or, in the case of Section 2.1, the JSC has
failed  to  commence  judicial, administrative or other proceedings reasonably
available under Colombian law against the expropriating authority for the
purpose of reversing or mitigating the effects of the Expropriatory Action.

                   ARBITRATION; SUBMISSION TO JURISDICTION

            Section 6.1.       Arbitration.   Any dispute under this Agreement
shall  be  settled  by arbitration in accordance with the UNCITRAL Arbitration
Rules  in  effect  on  the date hereof.  The arbitration shall be the sole and
exclusive  forum  for resolution of the dispute, controversy or claim, and the
award shall be final and binding.  Judgment thereon may be entered by any
court  having  jurisdiction.  The number of arbitrators shallbe three, each of
whom  shall  be  disinterested  in the dispute, controversy or claim and shall

authority be necessary, the appointing authority shall be the American
Arbitration Association.  In the event that more than two parties are involved
in  the  dispute, controversy or claim, all such parties shall have 30 days to
agree  among  themselves  as to the appointment of the three arbitrators.  If,
after such 30-day period, the parties have not agreed on such appointment, the
appointing  authority shall select all three arbitrators.  The parties and the
appointing authority may appoint from among the nationals of any country,
whether or not a party is a national of that country. The place of arbitration
shall  be  The City of New York, New York.  The arbitration shall be conducted
in  the  English language and any foreign-language documents presented at such
arbitration shall be accompanied by an English translation thereof.  The
arbitrators  shall  apply  the  law (except for conflicts of law rules) of the
State of New York.

<PAGE>
           (a)     In the event that there is an existing arbitration pursuant
to paragraph (b), and that the same or a similar disagreement, dispute,
controversy  or  claim  should arise between parties other than the parties to
the  existing arbitration, the American Arbitration Association shall have the
power to allow the other parties to be joined in the existing arbitration with
their  express  consent,  which  is hereby granted, and to make a single final
award determining all disputes, controversies or claims among them.

             (b)     Any matter expressed in this Agreement to be a matter for
review,  collaboration,  consultation,  consent,  decision or agreement by the
parties or any of them shall not, in the event of failure of decision or
agreement,  constitute a dispute or difference to be referred to or settled by
arbitration proceedings.

           Section 6.2.       Submission to Jurisdiction.  Each of the parties
hereby  submits  to  the  exclusive jurisdiction of the United States District

it objects to the instruction notice but thereafter notifies the Escrow Agent
that it is withdrawing the objection.  In no event shall the Escrow Agent be
obligated to distribute any amount in excess of the funds in the Escrow
Account at the time the distribution is made.

           5.     Books and Accounts.  (a)     The Escrow Agent shall maintain
all  such  accounts,  books and records as may be necessary properly to record
all  transactions  carried  out  by it under this Agreement.  The Escrow Agent

          (c)     The Escrow Agent shall have no duties other than those
specifically set forth or provided for in this Agreement and no implied
covenants or obligations of the Escrow Agent shall be read into this
Agreement.    The  Escrow Agent shall have no obligation to familiarize itself
with and shall have no responsibility with respect to any obligation to
inquire whether any notice, instruction, statement or calculation is in
conformity with the terms of any such other agreement, except those
irregularities  or  errors manifestly apparent on the face of such document or
to  its  actual knowledge.  The Escrow Agent shall at all times take such care
in  dealing with the Escrow Account as would a prudent man in dealing with his
own property.

              8.     No Set-offs.  The Escrow Agent shall not have, and hereby
waives, any right to banker's lien, set-off or counterclaim in respect of
funds or investments in the Escrow Account.

          9.     Expenses; Indemnification.   (a)     The Escrowing Party
shall  pay  directly  and not out of the Escrow Account the fees of the Escrow
Agent  for the services rendered pursuant or relating to this Escrow Agreement
chargeable  in accordance with the Escrow Agent's usual rate of compensation.
The JSC shall have no obligation to pay the Escrow Agent any fees.

          (b)     The Escrowing Party agrees to indemnify the Escrow Agent and
hold it harmless against any and all losses, liabilities and expenses
(including reasonable attorney's fees and expenses) incurred by it arising out
of  or in connection with the performance of its duties hereunder except those
resulting  from its own willful misconduct or gross negligence.  The foregoing
indemnities shall also extent to each and every employee and agent of the
Escrow Agent and shall remain in full force and effect regardless of any
investigation  made  by  or on behalf of the Escrow Agent or its employees and
agents,  and survive the resignation of the Escrow Agent and thetermination of
this Agreement.  The JSC shall have no indemnification obligation to the
Escrow Agent.

<PAGE>
              10.     Resignation; Removal.      (a)   The Escrow Agent at any
time  may resign as escrow agent under this Agreement upon given not less than
60 days' notice in writing to the Parties, provided that such resignation
shall not be effective until a replacement Escrow Agent reasonably
satisfactory to the Parties shall have been appointed.  The Parties may remove
the  Escrow Agent as escrow agent under this Agreement for any reason, with or
without cause, upon given the Escrow Agent and the other party hereto 60 days'
notice thereof; provided that such removal shall not be effective until a
replacement Escrow Agent satisfactory to the Parties shall have been
appointed.

            (b)     If no successor Escrow Agent shall have been appointed and
shall have accepted such appointment within such 60-day period, then the
retiring Escrow Agent may on behalf of the Parties, appoint a successor Escrow
Agent  which shall be a commercial bank organized under the laws of the United
States  of  America  or of any State thereof and having a combined capital and
surplus  of  at least U.S.$500,000,000.  If a successor escrow agent shall not
have  been  appointed and accepted such appointment within such 60-day period,
the retiring Escrow Agent may petition any court of competent jurisdiction for
the appointment of a successor Escrow Agent.

              11.     Miscellaneous.  (a)      The Escrow Agent shall have the
right  at  any  time to seek instructions concerning the administration of the
Escrow  Account from any court of competent jurisdiction.  In the event of any
disagreement between the Parties resulting in adverse claims being made
against  or with respect to any cash, monies, funds or investments held by the
Escrow  Agent  hereunder  and the terms of this Agreement do not unambiguously
mandate  the action that the Escrow Agent is to take or not take in connection
therewith  under  the  circumstances  then existing, or the Escrow Agent is in
doubt  as  to what action it is required to take or not take, the Escrow Agent
shall not be entitled to refrain from taking any action until directed
otherwise in writing by a request signed jointly by the Parties or by order of
a court of competent jurisdiction.

           (b)     None of the provisions of this Agreement shall be construed
to  require  the  Escrow Agent to expend or risk its own funds or otherwise to
incur any personal financial liability in the performance of any of its duties
hereunder  if  it  shall  have reasonable grounds for belief that repayment of
such funds or indemnity against such risk or liability is not reasonably
assured  to it.  The Escrow Agent shall be under no obligation to exercise any
of the rights or powers vested in it by this Agreement at the request or
direction  of  the  Escrowing  Party or the JSC, unless the Escrow Agent shall
have  been offered security or indemnity reasonably satisfactory to it against
the costs, expenses and liabilities which might be incurred by it in
compliance with such request or direction (including interest thereon from the
time incurred until reimbursed).

<PAGE>
                  (c)     The Escrow Agent makes no representations as to, and
shall  have  no responsibility for, the correctness of any statement contained
in,  or  the validity or sufficiency of, this Agreement, or the sufficiency or
effectiveness  of  any security afforded hereby or thereby or as to or for the
validity  or collectibility of any obligation contemplated hereby or thereby.
The  Escrow  Agent  shall not be accountable for the use or application by any
person  of  distributions properly made by the Escrow Agent in conformity with
the provisions of this Agreement.

                   (d)     The Escrow Agent shall not be personally liable for
debts contracted or liabilities or damages incurred in the management or
operations  of  the  Escrow  Account hereunder, except for those contracted or
incurred as a result of its gross negligence or willful misconduct.

               (e)     Escrowing Party shall provide the Escrow Agent with its
Tax  Identification Number (TIN) as assigned by the Internal Revenue Service.
All interest or other income earned under the Escrow Agreement shall be
allocated and paid to Escrowing Party as provided herein and reported by
Escrowing  Party  to  the Internal Revenue Service as having been so allocated
and paid.

               12.     Termination.  When all funds in the Escrow Account have
been distributed pursuant to Section 4, the Escrow Agent shall promptly
deliver  written notice of that fact to the Parties.  On the 10th Business Day
following delivery of such notice, this Agreement shall terminate.

            In the event of the termination of this Agreement pursuant to this
Section  12,  this  Agreement shall thereafter become void and have no effect,
and no Signatory hereto shall have any liability to any other Signatory hereto
in respect thereof, except that nothing in this Section shall relieve any
Signatory from liability for any breach of this Agreement prior to
termination.  No Signatory shall in any event be liable to any other Signatory
for  loss  of  anticipated  profits from the transactions contemplated by this
Agreement or for any other consequential damages arising out of the
termination of this Agreement.

                  13.     Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY,
AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                                   RECITALS

WHEREAS:

            A.  _______________, a ___________ corporation organized under the
laws  of ___________ (the "Company"), the JSC and the Funding Shareholders are
parties  to  a  Political  Events Agreement, dated as of December 14, 1994 (as
amended  from  time  to  time, the "Political Events Agreement"), entered into
pursuant  to  the  Oleoducto  Central Agreement, dated as of the same date (as
amended from time to time, the "Oleoducto Central Agreement");

          B.  The Company is an Affiliate of the Guarantor; and

          C.  As an inducement to the JSC and the Funding Shareholders to
enter  into  the Political Events Agreement, the Guarantor has agreed to enter
into this Political Events Performance Guarantee Agreement (the "Agreement").

          NOW, THEREFORE, in consideration of the premises and the mutual
covenants  herein contained and for other good and valuable consideration (the
receipt  and  sufficiency of which is hereby acknowledged), the Guarantor, the
JSC and the Funding Shareholders agree as follows:

of  its  obligations  under,  this Agreement will not result in a breach of or
constitute a default under:

                    (i)  any provision of its corporate charter or articles of
incorporation or its by-laws;

         (ii)  any agreement or instrument to which it is a party and which is

Political  Events Agreement or any judgment against the Company; provided that
it is hereby acknowledged and agreed that (a) the Guarantor shall not be

              Section 5.  No Waiver.  No failure on the part of the JSC or any
Funding Shareholder to exercise, and no delay in exercising, any right, remedy
or  power hereunder shall operate as a waiver thereof, nor shall any single or
particular exercise by the JSC or any Funding Shareholder of any right, remedy
or  power  hereunder preclude any other or future exercise of any other right,
remedy or power.

<PAGE>
            Section 6.  Subrogation.  The Guarantor shall be subrogated to all
rights  of the JSC and the Funding Shareholders against the Company in respect
of any amounts paid by the Guarantor pursuant to the provisions of this
Agreement; provided, however, that the Guarantor shall not be entitled to
enforce,  or  to receive any payments arising out of or based upon, such right
of  subrogation  until  all  of the Guaranteed Obligations under the Political
Events Agreement shall have been performed in full, all the Senior Debt
referred  to  in the Oleoducto Central Agreement provided by the Senior Lender
Group for whose benefit the Political Events Agreement to which the Company is
party  may be assigned by the JSC has been repaid and all other obligations of
the  Company owed to the JSC and the Funding Shareholders have been discharged

connection  with  the  simultaneous  direct or indirect transfer of all or any
part of the Shares held by the Company to a Person that is a permitted
transferee thereof pursuant to Article Ten of the Oleoducto Central Agreement,
such  permitted transferee assumes or undertakes the related obligations under

performance guarantee agreement in substantially identical form to this
Agreement.

          Section 12.  Severability.  If, for any reason, any provision of
this Agreement is unenforceable, the remaining provisions hereof shall
nevertheless be carried into effect.

          Section 13.  Governing Law.  THIS AGREEMENT SHALL BE GOVERNED BY AND
CONSTRUED  IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICTS OF LAWS.

             Section 14.  Submission to Jurisdiction; Consent to Service.  The
Guarantor  hereby submits to the non-exclusive jurisdiction of the Federal and
State courts in the Borough of Manhattan in The City of New York (the
Specified  Court) in any action, suit or proceeding arising out of or relating
to this Agreement or the transactions contemplated hereby (a "Related
Proceeding").  The Guarantor irrevocably appoints the agent for service
designated  opposite  its name in Section 11 hereof as its authorized agent in
the  Borough  of  Manhattan  in The City of New York upon which process may be
served in any such action, suit or proceeding, and agrees that service of
process  upon such agent, and written notice of said service to the Guarantor,
by the person serving the same to the address provided in Section 11, shall be
deemed  in  every  respect effective service of process upon such party in any
such  suit  or  proceeding.   The Guarantor further agrees to take any and all
action  as  may  be  necessary to maintain such designation and appointment of
such agent in full force and effect for the duration of this Agreement.

          The obligation of the Guarantor in respect of any sum due from it to
the  JSC expressed in United States dollars, notwithstanding any judgment in a
currency  other  than United States dollars, shall not be discharged until the
first  Business  Day following receipt by the JSC of any sum adjudged to be so
due  in such other currency on which (and only to the extent that) the JSC may
in  accordance  with  normal banking procedures purchase United States dollars
with  such other currency.  If the United States dollars so purchased are less
than  the sum originally due to the JSC or the Funding Shareholders hereunder,
the  Guarantor  agrees,  as a separate obligation and notwithstanding any such
judgment,  to  indemnify the JSC against such dollar shortfall.  If the United
States dollars so purchased are greater than the sum originally due to the JSC
or the Funding Shareholders hereunder, the JSC or the Funding Shareholders, as
the  case  may be, agree to pay to the Guarantor an amount equal to the excess
of  the  dollars so purchased over the sum originally due hereunder to the JSC
or the Funding Shareholders, as the case may be.

                                                TO OLEODUCTO CENTRAL AGREEMENT


                              TARIFF PRINCIPLES


THE OLEODUCTO CENTRAL

             Segments.  The Oleoducto Central shall consist of four segments:
the  Cusiana-El  Porvenir  segment,  the El Porvenir-Vasconia (Central Llanos)
segment, the Vasconia-Covenas (the ODC loop) segment and the delivery
facilities at the Covenas Terminal (each, a "Segment").

            Capacity.  For purposes of determining the Proportionate Shares of
Throughput Capacity assigned to the Initial Shippers and determining the
tariffs applicable to the different types of shippers, the Throughput Capacity
of each Segment (the "Throughput Capacity") shall be the initial average
annual  throughput capacity of such Segment.  After giving effect to a service
factor  of  85%,  the initial average annual throughput capacity (the "Initial
Average Annual Throughput Capacity") of each Segment is set forth below:

<TABLE>
<CAPTION>

<S>                   <C>
                      Initial Average Annual
                      Throughput   Capacity

Segment               (Average Annual barrels/day)

Cusiana-El Porvenir                        500,000
El Porvenir-Vasconia                       556,000
Vasconia-Covenas                           290,000
Covenas Terminal                           500,000

</TABLE>

The  Throughput  Capacity  of any Segment shall never be less than the Initial
Average  Annual Throughput capacity thereof (i) unless otherwise agreed by all
of  the Initial Shippers or (ii) due to events outside the control of the JSC,
in which case such Throughput Capacity shall be the actual volume of Petroleum
shipped  through such Segment for tariff purposes.  The Throughput Capacity of
any  Segment  shall  never be less than the actual volume of Petroleum shipped
through  such  Segment.  The Throughput Capacity of each Segment shall be used
to determine available capacity for tariff purposes for transportation of
Petroleum through such Segment.
             Capacity for purposes of determining actual operating capacities,
operating  fees,  incentive  fees  and other payments to the Operator shall be
determined in accordance with the Operating Principles.

<PAGE>
INITIAL SHIPPERS

           In accordance with the terms of the Transportation Agreements, each
of  the  Initial Shippers (i) shall reserve and dedicate to the performance of
its  obligations thereunder all of its Petroleum production resulting from its
interest  in  the  Association Contracts relating to the Fields and (ii) shall
have  transportation  rights  to use its Proportionate Share of the Throughput
Capacity  of  each Segment of the Oleoducto Central.  The Proportionate Shares
of each Initial Shipper are set forth below:

               Ecopetrol               60%
               BPEC                    15.2%
               TOTAL Exploratie          15.2%
               Triton Colombia          9.6%

COMMITMENT OF PRODUCTION FROM FIELDS

          For purposes of calculating tariffs, all barrels of Petroleum
produced  by  each Initial Shipper from the Fields shall be shipped, or deemed
to  be  shipped  up to its Proportionate Share of Throughput Capacity, by such
Initial  Shipper from the Cusiana access point to the Port of Covenas delivery
point, regardless of whether production is directed elsewhere.  A deemed
barrel for an Initial Shipper in any segment is a barrel produced by such
Initial Shipper from the Fields but not nominated for shipment in such
segment.  A barrel deemed to be shipped may be substituted with Petroleum
owned  by  such  Initial Shipper or an Affiliate thereof but produced at other
fields,  but  the  tariff  applicable thereto shall be adjusted to reflect any
difference  in  the  quality of such Petroleum as described under "Calculation
and  Payment  of  Tariffs   Quality Adjustments."  The JSC shall enter into an
agreement  with  the  Operator of the Fields whereby the Operator will provide
the JSC with monthly reports of actual production from the Fields.

ADVANCE TARIFF AGREEMENTS

            To the extent that the Advance Tariff Agreement provisions are not
contemplated  in  a Transportation Agreement or Transportation Notes Agreement
with  respect  to  a member of an Initial Shipper Group, such member agrees to
enter into, or to cause an Affiliate thereof or financial institution
acceptable to the unrelated Shareholders to enter into, an Advance Tariff
Agreement with the JSC.

ANNUAL REVENUE REQUIREMENT

          The tariffs applicable to each Segment of the Oleoducto Central
shall be calculated in advance based on the estimated annual revenue
requirement  of  the  JSC  with respect to such Segment, as determined in each
Annual  Operating  Budget  approved by the Board of Directors, and the capital
cost thereof as adjusted from time to time in accordance herewith (the "Annual
Revenue  Requirement").  The Annual Revenue Requirement for each Segment shall
be adjusted monthly by the Operator pursuant to authority delegated by the

<PAGE>
Board of Directors to reflect differences between costs estimated in the
Annual  Revenue  Requirement for such Segment and actual costs incurred by the
JSC, exchange rates, actual volumes of Petroleum shipped through such Segment,
and changes in forecasts for future periods.  The Operator will provide a
quarterly  (or more frequently as appropriate) revised forecast for the entire
fiscal year to the Board of Directors reflecting actual results on a
year-to-date  basis  with revised projections for the remainder of such year.
The  Board  of  Directors  shall decide whether to adopt or amend this revised
forecast.   If approved, tariffs for the remainder of the year will be revised
accordingly.  Except as otherwise provided herein, the Annual Revenue
Requirement for any Segment in any year shall be the estimated sum of

       (1)  the JSC's Operating and Maintenance Costs (excluding all Colombian
Taxes),

     (2)  accounting depreciation of the JSC's fixed assets using the
straight-line  method  and  (for both tax and financial accounting purposes) a
15-year useful life,

     (3)  the Benchmark Interest Expense (as hereinafter defined),

       (4)  foreign currency translation costs related to non-peso denominated
items,

     (5)  all Colombian Taxes,

        (6)  the amount necessary to establish the legal reserve of the JSC in
accordance with Colombian law,

     (7)  the annual return to be paid to Shareholders (including any interest
paid on Subordinated Notes) in accordance with Section 5.4(b) of the Oleoducto
Central Agreement and the Subordinated Fee payable to the Operator, and

     (8)  inflation adjustments on non-monetary items,

in  each  case  with  respect to such Segment for such year.  Items 2, 6 and 8
constitute  the  "Non-Cash  Items"  of the tariff.  The JSC shall allocate all
costs  directly attributable to a Segment to such Segment.  Indirect costs not
specifically  attributable  to  any Segment shall be allocated to each Segment
pro  rata  to its capital cost.  The capital cost of each Segment, which shall
be  determined  by  unanimous agreement of the Parties at the time the Parties
determine the Actual Project Cost, shall be comprised of the direct costs
(acquisition  or  construction)  and indirect costs incurred by the JSC during
the period up to commissioning of such Segment.  The Annual Revenue
Requirement shall only be allocated to Segments that have been put in service,
and have not been removed for the purposes of tariffs by agreement of all
Initial Shippers.  Unless the context otherwise requires, references to
"Annual Revenue Requirement" shall mean the sum of the Annual Revenue
Requirements for each Segment.

<PAGE>
          The Annual Revenue Requirement for each Segment shall be fully
recovered from all barrels of Petroleum shipped or deemed to be shipped
through  such  Segment.  In the event that no barrels of Petroleum are shipped
or deemed to be shipped, each shipper will be obligated to pay minimum tariffs
as set forth below in accordance with the Transportation Agreements,
Transportation Notes Agreements and Advance Tariff Agreements.

          On December 31 and June 30 of each year, the JSC shall make an
adjustment  to the Annual Revenue Requirement and tariffs to take into account
a  conservative forecast of the peso/dollar exchange rate on the expected date
of  any  dividend  or distribution payment with respect to the six months then
ended.    If, however, the peso/dollar exchange rate on the actual dividend or
distribution  payment date is such that the dividend or distribution is higher
or lower than the return to Shareholders contemplated by Section 5.4(b) of the
Oleoducto  Central  Agreement, tariffs shall be adjusted in the subsequent six
month period so that the dividends or distributions with respect to the
subsequent  period  may be decreased or increased and the aggregate return for
the period beginning on the date of the first Equity Contribution to such
dividend or distribution date made equal to the return to Shareholders
contemplated by Section 5.4(b) of the Oleoducto Central Agreement.

BENCHMARK INTEREST EXPENSE

            The Initial Shipper Tariff for each barrel of oil actually shipped
in  a  Segment  shall  be the same for each Initial Shipper.  The Overutilizer
Tariff  for each barrel of oil actually shipped in a Segment shall also be the
same  for each Initial Shipper. In order to provide for the different interest
rate  and principal repayment schedules that will apply (i) to the Senior Debt
with respect to which the right to receive tariff payments under the
Transportation  Agreement of each Initial Shipper shall be assigned by the JSC
(with  respect to such Initial Shipper, the "Related Senior Debt") and (ii) to
the  Transportation  Notes (with respect to such Initial Shipper, the "Related
Transportation  Notes"),  the  interest  expense used in the estimation of the
Annual Revenue Requirement shall be calculated applying the Benchmark Interest
Rate  (as  hereinafter defined) on all outstanding Senior Debt and outstanding
Transportation Notes (the "Benchmark Interest Expense").  The Benchmark
Interest  Rate  will  be  the highest of the weighted average interest rate on
Related  Senior  Debt  of all Initial Shippers.  The weighted average Interest
Rate  for  each  Initial  Shipper shall be the ratio of (a) the total interest
expense  on  the  Related  Senior Debt and (b) the total outstanding amount of
such  Related Senior Debt. The Benchmark Interest Rate shall be computed every
time the JSC raises new amounts of Senior Debt (excluding Transportation
Notes)  and will not be updated after all Senior Debt has been raised.  Before
any Senior Debt has been raised the Benchmark Interest Rate shall be U.S.
Treasury  Notes  + 200 basis points based on a  maturity of 10 years. For each
Initial Shipper, the difference between the Benchmark Interest Expense charged
in  the  tariffs  on  such Senior Debt and Transportation Notes and the actual
interest  expense  paid  on the Related Senior Debt and Related Transportation
Notes  of  an Initial Shipper shall be fully credited by the JSC as a discount
to be applied to the tariffs paid by such Initial Shipper, to be paid in cash,
as  a  guarantee fee or by any other method approved by the JSC as directed by
the  Senior Lender Group that provided such Senior Debt or to the purchaser of
Transportation  Notes for the purpose of paying the guarantor thereof, in each
case as directed by the member of the Initial Shipper Group that is the
Initial Shipper.

TARIFFS DURING ASSET TRANSFER PERIOD

            From January 1, 1995 until such date as the completion of the sale
by Ecopetrol to the JSC of all assets has occurred in accordance with the
Promesas de Compraventa, all shippers transporting Petroleum using such assets
shall pay the tariff established by the Colombian Ministry of Mines and Energy
(the  "MME") to Ecopetrol as operator of such assets.  Ecopetrol shall in turn
pay to the JSC a monthly fraction of such tariffs, net of operating and
maintenance  costs, equal to (x) the sum of the total value of the assets sold
to the JSC and the advances to Ecopetrol by the JSC under the Promesas de
Compraventa divided by (y) the total value of the assets on which such tariffs
are being levied and such tariff shall not be less than the result of applying
the approved MME rate of return on investment on the sum of the value of
assets  sold  to the JSC and the advances.  Following completion of such sale,
the  JSC shall charge and collect tariffs on the assets sold to it (including,
without  limitation, the Central Llanos 30" pipeline) calculated in accordance
with these Tariff Principles.

            After completion of the Promesas de Compraventa, the JSC shall pay
lease rentals or tariffs, on assets owned by Ecopetrol and other Initial
Shippers which will be used by the JSC temporarily during construction,
including  but  not limited to the Central Llanos 20" pipeline and the Cusiana
El  Porvenir 20" pipeline.  Tariff or rental costs shall be agreed between the
JSC  and  the  owners of the assets prior to the completion of the Promesas de
Venta.    Tariffs  charged  to the JSC by the owners of the Central Llanos 20"
pipeline shall be the tariff approved by the MME multiplied by a fraction
equal  to the value of such assets divided by the value of the assets on which
such  tariff  is  levied.  The tariff for the Cusiana-El Porvenir 20" pipeline
shall  be  agreed between the owners thereof and the JSC.  These costs will be
included in the Annual Revenue Requirement for the corresponding Segment.

            There will also be a tariff applicable to the assets to be sold to
the  JSC covered by the Association Contracts, i.e. Cusiana Pumps and Drivers,
but  only  after the date ownership of such assets is transferred to the JSC.
The tariff applicable will be calculated in accordance with these Tariff
Principles.  Prior to that date, any costs related to such assets shall be for
the account of the Parties to the Association Contracts.

CALCULATION AND PAYMENT OF TARIFFS

             The tariffs applicable to the transportation of Petroleum through
each Segment of the Oleoducto Central shall be estimated and posted monthly in
advance by the JSC on a per barrel of Petroleum basis based on the Annual
Revenue  Requirement and the aggregate monthly nominations for such Segments.
Tariffs shall be expressed in dollars or, if the JSC so requests, the
equivalent of all or any portion thereof in pesos. Tariffs may be paid in
either cash or, at the election of the JSC, in oil which has been delivered to
the  Port of Covenas terminal, all in accordance with the procedures to be set
forth in the Transportation Agreements.  Such estimated tariffs shall be
payable  monthly in arrears and shall be billed at the end of each month.  The
final reconciling bill for tariffs due from any

<PAGE>
shipper at the end of each six month period shall include an appropriate share
of any costs incurred during that period but not included in the initial
Annual  Revenue  Requirement and shall also specify the amount, if any, of any
required Working Capital Advance (as defined below).  Interest shall be
charged by the JSC to any defaulting shipper on overdue tariffs (i)
denominated in pesos at an interest rate equal to the highest default interest
rate  permitted  by law and (ii) denominated in dollars at the annual interest
rate implied by the Benchmark Interest Expense plus 5% per annum.  In
addition, the other default provisions under the Transportation Agreement
shall apply.

          Initial Shipper Tariff.  Initial Shippers who ship Petroleum through
a Segment in a volume equal to or less than their Proportionate Share of
Throughput  Capacity  of  such Segment determined monthly shall pay the tariff
per barrel applicable to Initial Shippers (the "Initial Shipper Tariff").  The
Initial Shipper Tariff for any Segment for any period is the sum of:

      (1)  the Annual Revenue Requirement for such Segment in such period, net
of the variable operating costs to be defined in the Transportation Agreements
directly associated with shipping one barrel of Petroleum through such Segment
multiplied  by  the actual number of barrels of Petroleum shipped through such
Segment in such period (the "Variable Operating Costs"), divided by the sum of
all  barrels of Petroleum nominated for shipment plus all barrels of Petroleum
deemed  to  be shipped through such Segment in such period by Initial Shippers
(including  barrels  of  Petroleum  shipped at the Overutilizer Tariff) and by
Third  Parties.   These costs shall be paid on all barrels nominated or deemed
to be shipped; and

      (2)  the Variable Operating Costs for such Segment divided by the sum of
all  barrels of Petroleum nominated for shipment (excluding any barrels deemed
to be shipped) through such Segment in such period.  These costs shall be paid
on all barrels of Petroleum nominated for shipment.

              Overutilizer Tariff.  The tariff paid by an Initial Shipper with
respect to a volume of Petroleum shipped in a Segment in excess of its
Proportionate  Share of Throughput Capacity of such Segment (the "Overutilizer
Tariff") shall be set at a premium to the Initial Shipper Tariff for such
Segment.  The total premium shall be equal to the increase in the Annual
Revenue  Requirement  necessary to increase the JSC's annual return calculated
in  accordance  with  Section 5.4(b) of the Oleoducto Central Agreement by one
percentage point after payment of all Colombian Taxes, provided, however, that
the  Overutilizer Tariff shall (i) never be higher than the Third Party Tariff
for such Segment, or (ii) lower than the Initial Shipper Tariff for such
Segment.  The total premium shall be allocated to each Segment pro rata to its
capital  cost.  The quarterly overutilizer premium per barrel of Petroleum for
such  Segment  shall  be  the total premiums divided by the sum of all barrels
nominated for shipment and deemed to be shipped through the Segment by Initial
Shippers.   All barrels of Petroleum with respect to the shipment of which the
Overutilizer  Tariff  is  paid  shall pay on a quarterly basis an overutilizer
premium, per barrel of

<PAGE>
Petroleum,  in  addition  to the Initial Shipper Tariff, as calculated above.
The sum of all such payments shall constitute the quarterly overutilizer
premium payment.  Premiums to the Initial Shipper Tariff included in the
Overutilizer  Tariff  paid  with respect to throughput in any Segment shall be
credited  by  the  JSC against tariffs paid by each Initial Shipper for use of
such Segment during such period pro rata to such Initial Shipper's
Proportionate  Share  of  Throughput Capacity of such Segment made effectively
available for shipments of barrels of Petroleum with respect to which the
Overutilizer Tariff was paid.

             Third Party Tariff.  The tariff paid by Third Parties (the "Third
Party  Tariff")  must  be approved by the MME.  The Shareholders agree to seek
approval  from the MME to establish the Third Party Tariff at a premium to the
Initial  Shipper  Tariff  equal  to the increase in the Initial Shipper Tariff
necessary to increase the JSC's annual return on equity as calculated in
accordance with Section 5.4(b) of the Oleoducto Central Agreement by two
percentage points after payment of all Colombian Taxes (the "Third Party
Premiums")  and  performing the calculation analogous to that for overutilizer
premiums  in respect of all barrels of Petroleum shipped, including barrels of
Petroleum nominated by Initial Shippers and Third Parties (not including
barrels deemed to be shipped).  The Third Party Premium shall be designated as
the  difference  between the Third Party Tariff and the Initial Shipper Tariff
as calculated above.

           During the construction of the Oleoducto Central and until December
31,  1997,  Third  Party  Tariff revenues, if any, net of Third Party Premiums
revenue, and net of implied revenues derived from barrels of Petroleum shipped
by  Third  Parties at the Initial Shipper Tariff (i.e. the nominated number of
barrels shipped by Third Parties multiplied by the Initial Shipper Tariff (the
"Implied  Third Party Revenues")), for each Segment during any period shall be
credited  by  the JSC against tariffs paid by each Initial Shipper during such
period  pro  rata to each Initial Shipper's actual throughput; and Third Party
Premiums  revenue,  if any, shall be credited to Initial Shippers according to
the proportion of their Proportionate Share of Throughput Capacity made
available  to  third parties.  After such date Third Party Tariff revenues, if
any, including Third Party Premiums revenue, shall be credited to Initial
Shippers  according  to  their  Proportionate Shares.  The Implied Third Party
Revenues shall be credited to the Initial Shippers pro rata to throughput
nominations to avoid double counting of barrels shipped by Third Parties.

             The Shareholders agree that if (i) the Third Party Tariff is less
than  the  Third Party Tariff as proposed above and under applicable Colombian
law  tariffs  higher  than  the MME Third Party Tariff cannot be collected, or
(ii) as a result of any change in Colombian laws generally, the JSC has
insufficient  earnings  to provide the returns to Shareholders provided for in
Section  5.4(b) of the Oleoducto Central Agreement, the Initial Shippers shall
take all reasonable commercial measures available under Colombian law to
effect  changes  to these Tariff Principles or make any other economic changes
necessary (including the imposition of charges or fees on the Oleoducto
Central) to achieve the returns to shareholders provided for in Section 5.4(b)
of the Oleoducto Central Agreement without in any respect prejudicing the
economic interests of the Initial Shippers and Shareholders as they are
contemplated in these Tariff Principles and the Oleoducto Central Agreement.

<PAGE>
           Quality Adjustments.  If Petroleum from an Initial Shipper produced
from the Fields and to be shipped or deemed to be shipped in one or more
Segments  by  an Initial Shipper is actually substituted by Petroleum owned by
such  Initial Shipper or an Affiliate thereof but produced at other fields, or
if any shipper transports Petroleum produced from fields other than the
Fields,  the  tariffs for such substituted or other Petroleum, as the case may
be, shall be adjusted to reflect the different cost of transporting such
substituted or other Petroleum due to the physical differences between
Petroleum  produced  from  the  Fields and such substituted or other Petroleum
based on standard industry quality adjustments administered by the Operator.

            Excess Credits.  To the extent premiums or revenues to be credited
to the payment of tariffs by an Initial Shipper in any period exceed the
tariffs  to  be paid by such Initial Shipper in such period, such excess shall
be  applied  by  the  JSC to tariffs to be paid by such Initial Shipper in the
following period or periods or paid in cash by the JSC to such Initial Shipper
or paid as a dividend to the Shareholder that is a member of the related
Initial  Shipper  Group as long as it does not affect the economic interest of
any other Initial Shipper Group or any other Shareholder.

MINIMUM TARIFFS UNDER TRANSPORTATION AGREEMENTS

              Under its Transportation Agreement or, in the case of an Initial
Shipper,  its   Advance Tariff Agreement or Transportation Notes Agreement, as
the case may be, in any period when no Petroleum is being shipped in a
Segment,  each  shipper  shall  be obligated to pay minimum tariffs to the JSC
according  to its average nominated and deemed volumes shipped in such Segment
during  the previous six months of production or such other time period as may
be  agreed.  Such minimum payments in such period shall be calculated based on
its  pro  rata  share,  based on such throughput, of Operating and Maintenance
Costs subject to the Oleoducto Central Operations Agreement.

WORKING CAPITAL ADVANCES UNDER TRANSPORTATION AGREEMENTS

           Under its Transportation Agreement, each shipper shall be severally
obligated pro rata to its throughput nomination to provide the JSC at the
beginning of any fiscal year with a cash advance (a "Working Capital Advance")
designed to provide the JSC with adequate working capital for such year.
Working  Capital  Advances  shall  be included in each Annual Operating Budget
approved by the Board of Directors and shall be a specified percentage of
Operating  and  Maintenance Costs included in the Annual Revenue Requirement.
Working  Capital  Advances  shall not bear interest and shall be repaid by the
JSC  at  the  end of such year from Available Cash.  If at the end of any year
Available  Cash is not sufficient to repay Working Capital Advances, the final
tariff adjustment for such year shall be increased in order to generate
sufficient Available Cash to repay such Working Capital Advances.

<PAGE>
TARIFF ADVANCES AND TRANSPORTATION NOTES

            To the extent that an Initial Shipper's Proportionate Share of the
JSC's Non-Cash Items in any period is less than the amount of the JSC's
principal  repayment  of  such  Initial Shipper Group's Related Senior Debt in
such  period,  such Initial Shipper, pursuant to its Transportation Agreement,
or  an  Affiliate or a financial institution acting on its behalf, pursuant to
its  Transportation  Notes Agreement with the JSC, shall severally provide the
JSC with such amount in cash advances ("Tariff Advances") or purchase
subordinated notes of the JSC (such Tariff Advances and notes together
referred  to  herein  as "Transportation Notes") in order to permit the JSC to
make such  repayment.  Unless unanimously agreed by the Initial Shippers,
Transportation  Notes  shall  bear interest at the Benchmark Interest Rate and
shall have an ascertainable maturity beyond the maturity of the Related Senior
Debt and before the full depreciation of the JSC's assets.  The JSC shall
repay Transportation Notes in cash to the related Initial Shipper, if and when
the JSC has Available Cash and subject to its policy expressed in Section
5.4(a) of the Oleoducto Central Agreement and the requirements of the
Financing,  in  any  period when such Initial Shipper's Proportionate Share of
the JSC's Non-Cash Items exceeds its Proportionate Share of any principal
amount of its Related Senior Debt due in such period.

ANNUAL SUBORDINATED FEE PAYABLE TO OPERATOR

            The Annual Revenue Requirement shall include an amount designed to
generate  a  subordinated fee (the "Subordinated Fee") payable to the Operator.
The  Subordinated  Fee shall be calculated annually and paid semi-annually as,
if  and  when the JSC pays cash dividends to the Shareholders.  Payment by the
JSC of the Subordinated Fee shall be subject to the same restrictions
applicable  to the receipt of cash dividends by the Canadian Group as provided
in the Dividend Trust Agreement.

          The Subordinated Fee shall be calculated annually in an amount equal
to a specified percentage multiplied by the Canadian Group's Shareholding
Interest of (i) prior to the Dividend Commencement Date, the sum of Cash
Paid-In Equity and Pre-Completion Accrued Returns and thereafter (ii) the
Adjusted  Paid-In  Equity,  in each case determined in accordance with Section
5.4(b)  of  the  Oleoducto Central Agreement.  The specified percentage in any
year  is subject to a maximum of 0.60% and a minimum of 0.40% provided that in
any year the specified percentage shall, when added to the specified
percentage  of  each  of  the previous years in which the Subordinated Fee was
paid by the JSC and divided by the number of such years, not exceed 0.50%.

             The specified percentage shall be determined based on the average
daily  volume  of  Petroleum actually shipped through the El Porvenir-Vasconia
(Central  Llanos)  Segment  in any year compared with the annual average daily
volume  of throughput forecast to be shipped in such year according to Annex I
attached hereto (the "Forecast"). The Forecast shall not be revised.  The
average  daily  throughput  volume in such Forecast includes significant Third
Party  and  overutilizer  volumes whose tariff revenues are projected to cover
wholly  or  in part the Subordinated Fee.  As long as the actual average daily
volume  of  Petroleum  shipped through such Segment is between 90% and 120% of
the average daily volume set forth in the Forecast for such year, the
specified percentage earned shall be 0.50% per annum.  When the actual average
daily volume shipped in such Segment in any year is less than 90% of the
average daily volume set forth in the Forecast for such

<PAGE>
year, the specified percentage earned shall be 0.40%.  When the actual average
daily volume shipped in such Segment in any year is greater than 120% of the
average daily volume set forth in the Forecast for such Segment for such year,
the specified percentage earned shall be 0.60%.  In determining the actual
average daily volume of Petroleum shipped, adjustments shall be made to
reflect certain force majeure events to be unanimously agreed by the
Shareholders.

            The Subordinated Fee shall be paid semi-annually in arrears at the
same  time as, if and when the JSC pays its first cash dividends in any fiscal
year  in  an  amount  using a deemed specified percentage equal to 0.25%.  The
second  installment  of  the Subordinated Fee shall be payable as, if and when
the  JSC  pays its second cash dividend with respect to such fiscal year in an
amount  such  that  the  Subordinated Fee in any one year shall not exceed the
limitations set forth in the second preceding paragraph.

            Annual Revenue Requirements shall incorporate the Subordinated Fee
based on a specified percentage of 0.50%.  Tariffs shall be adjusted upward or
downward should the specified percentage be 0.60% or 0.40%, respectively.

          The JSC shall pay the Subordinated Fee together with such additional
amounts as may be necessary so that the actual amount of dividends paid by the
Operator to its shareholders in respect of such Subordinated Fee shall be
equal to the amount of the Subordinated Fee before deduction for or on account
of any Colombian Taxes to be paid by the Operator in respect of such
dividends.    The  JSC shall have the right toreasonably inspect the books and
records of the Operator in  order to ensure that such taxes have actually been
paid by the Operator.

NOMINATION PROCEDURES

          Standard Nomination Procedures shall be agreed among the
Shareholders and included in the Transportation Agreements.  The Standard
Nomination Procedures shall implement the following principles:

     1.  Ensure orderly operations at all times.

     2.  Encourage accurate production estimates to be used for billing
tariffs and planning operations.

     3.  Allow for small errors in production scheduling without having a
punitive impact, except in cases of abuse (e.g. producing repeatedly more than
the quantity originally nominated).

     4.  In all respect be consistent with Colombian law and standard industry
practice.

          For purposes of the tariff calculations described herein,
"Nominations"  shall refer to planned shipments stated by the Initial Shippers
and  Third Parties in advance of the period in which their production is to be
shipped, and shall equally refer to the actual quantity of production received
for shipment after such period, as required by context and usage.

<PAGE>
TRANSPORTATION PRIORITIES

           When nomination requests are greater than the available capacity in
any  Segment,  the  following priority rights, except as otherwise required by
applicable law (e.g. royalty barrels, which shall be transported using
Ecopetrol's Proportionate Share), shall apply:

     1.     Production from the Fields in accordance with requests from
Initial Shippers and pro rata to their interests in the Fields.

     2.     Production of Initial Shippers from fields (other than the Fields)
wholly  or  partly  owned  by Initial Shippers, pro rata to requests from such
Initial Shippers.

      3.     Production by Third Parties, pro rata to requests from such Third
Parties,  giving  priority  to  production delivered upstream in the Oleoducto
Central,  subject  to  override by the Operator with the unanimous approval of
the Initial Shippers.

          Each Initial Shipper shall for the purpose of transporting Petroleum
use  the Oleoducto Central assets owned and operated by the JSC in priority to
all alternatives to transport Petroleum on any route joining any of the
Segments,  provided  that there is available Capacity in the Oleoducto Central
and that such use does not adversely affect such Initial Shipper.

EXISTING TRANSPORTATION ON EL PORVENIR-VASCONIA (CENTRAL LLANOS) SEGMENT

             The capacity of the El Porvenir-Vasconia (Central Llanos) Segment
allows for the transportation of Petroleum from fields other than the Fields.
In accordance with the agreement of the Initial Shippers under the Association
Contracts,  until  December  31, 1997 the El Porvenir-Vasconia (Central Llanos
Segment) shall give priority to the shipment of an aggregate of 100,000
barrels  of  Petroleum from fields other than the Fields.  Notwithstanding the
definition  of  Throughput  Capacity,  Ecopetrol shall be entitled to ship its
share of production at the Initial Shipper Tariff up to its Proportionate
Share of Throughput Capacity of such Segment (for example, average daily
volume  of  33,600  barrels of Petroleum in 1998) and shall be required to pay
the Overutilizer Tariff for any Petroleum shipped in excess thereof (for
example,  average  daily  volume of 11,200 barrels of Petroleum in 1998).  The
daily  transportation by third parties of the remaining expected average daily
production  of  11,200 in 1998 barrels of Petroleum shall be made at the Third
Party Tariff.  After December 31, 1997, the provisions of all of the
provisions of these Tariff Principles shall apply to such Segment.

SOLE RISK PROVISIONS

             The tariffs shall be adjusted appropriately to give effect to the
provisions contained in Article Six of the Oleoducto Central Agreement insofar
as they relate to the calculation of tariffs.

<PAGE>
POLITICAL EVENTS AGREEMENT

              The obligations of each Initial Shipper under its Transportation
Agreements and of each member of an Initial Shipper Group under its
Transportation  Notes  Agreement shall be subject to any rights exercisable by
it under the Political Events Agreement.

SEVERAL NATURE OF OBLIGATIONS

              The obligations of each Initial Shipper under its Transportation
Agreement and of each member of an Initial Shipper Group under its
Transportation Notes Agreement shall be entirely several.

DEFAULT TARIFFS

            The Initial Shippers agree that the Transportation Agreements will
provide  for  increases in tariffs in accordance with the provisions described
in Article Five of the Oleoducto Central Agreement.

Agreement  nor any of its rights, proceeds or obligations hereunder, or create
enforceable  third party rights herein, to or in any person not a party hereto
other than to a transferee of Shares to the extent such transferee is

consents  in  writing  (provided  that such other person shall assume, without
releasing  such Seller of its obligations hereunder) all of the obligations of
such Seller hereunder, which assumption shall be evidenced by its execution of
a counterpart hereof.

<PAGE>
     Section 4.4.  Nature of Obligations  (a)     The obligations of each
Seller under this Agreement to sell Shares shall be unconditional and absolute
and shall not be deferred, excused, released, discharged, or in any way
affected  by  (i)  any right of set off, counterclaim, or defense by reason of
any  claims against the Purchaser arising under this Agreement or on any other
account  whatsoever,  (ii)  any sale or other transfer by the Purchaser of any
Shares, or (iii) any change, waiver, extension, indulgence, or other action or
omission in respect of any of the Purchaser's obligations, in each case

any of the foregoing.

             (b)     The obligations of each Seller created by this Agreement,

except with the written consent of the parties hereto and any Permitted
Assignees.

     Section 4.6.  No Third Party Beneficiaries.  Except as otherwise

CONSTRUED  IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD
TO THE PRINCIPLES OF CONFLICTS OF LAWS.

agree that their activities hereunder shall be performed substantially outside

     Section 4.10.  Commercial Obligations.  Each party acknowledges and

        Section 4.11.  Arbitration.  Any dispute, controversy or claim arising
out of or relating to this Agreement, or the performance, breach, termination,
or  invalidity  hereof, shall be settled by arbitration in accordance with the

shall be the sole and exclusive forum for resolution of the dispute,
controversy or claim, and the award shall be final and binding. Judgment
thereon may be entered by any court having jurisdiction.  The number of
arbitrators shall be three, each of whom shall be disinterested in the
dispute,  controversy  or claim, and shall have no connection with any party.
Should  the  services  of an appointing authority be necessary, the appointing

rules)  of the State of New York without regard to the principles of conflicts
of laws.

       Section 4.12.  Submission to Jurisdiction; Consent to Service.  Each of
the  parties hereto hereby submits to the exclusive jurisdiction of the United
States  District  Court  for  the Southern District of New York (the "Specified
Court")  with  respect to the enforcement of the arbitration provisions of this
Agreement and the non-exclusive jurisdiction of such court with respect to the
enforcement  of  any award thereunder.  Each of the parties hereto irrevocably
appoints  the  agent for service specified opposite its name in Section 4.1 as
its  authorized agent in the Borough of Manhattan in The City of New York upon
which  process  may  be  served in any related action, suit or proceeding, and
agrees  that  service  of  process upon such agent, and written notice of said
service  to such party, by the person serving the same to the address provided
in  Section 4.1, shall be deemed in every respect effective service of process
upon  such  party in any such action, suit or proceeding.  Each of the parties
hereto further agrees to take any and all action as may be necessary to
maintain such designation and appointment of such agent in full force and
effect for the duration of this Agreement.

      The obligation of a party in respect of any sum due from it to the other
party hereunder expressed in United States dollars, notwithstanding any
judgment in a currency other than United States dollars, shall not be
discharged until the first Business Day following receipt by such party of any
sum  adjudged  to  be  so due in such other currency on which (and only to the
extent that) such party may in accordance with normal banking procedures
purchase  United States dollars with such other currency; if the United States
dollars so purchased are less than the sum originally due to such party
hereunder, the other party agrees, as a separate obligation and
notwithstanding any such judgment, to indemnify such party against such dollar
shortfall.  If the United States dollars so purchased are greater than the sum
originally  due to such party hereunder, such party agrees to pay to the other
party  an  amount equal to the excess of the dollars so purchased over the sum
originally due to such party hereunder.

        Section 4.13.  Waiver of Immunity.  (a)  Each party hereto irrevocably
consents to and waives any objection which it may now or hereafter have to the
laying  of  venue of any proceeding relating to enforcement of the arbitration
provisions of this Agreement brought in the Specified Court and further
irrevocably waives, to the fullest extent it may effectively do so, the
defense  of an inconvenient forum to the maintenance of any such proceeding in
the Specified Court.

      (b)  To the extent that a party hereto or any of its revenues, assets or
properties shall be entitled, with respect to any proceeding relating to
enforcement of the arbitration provisions of this Agreement at any time
brought against such party or any of its revenues,

<PAGE>
assets or properties, to any sovereign or other immunity from suit, from
jurisdiction,  from  attachment  prior  to judgment, from attachment in aid of
execution of judgment, from execution of a judgment or from any other legal or
judicial  process  or remedy, and to the extent that in any jurisdiction there
shall  be  attributed  such  an immunity, such party irrevocably agrees not to
claim  and irrevocably waives such immunity to the fullest extent permitted by
the laws of such jurisdiction (including, without limitation, the Foreign
Sovereign  Immunities  Act  1976 of the United States) except, with respect to
the  Purchaser,  as  provided under Article 684 of the Codigo de Procedimiento
Civil of Colombia.

more counterparts, each of which shall be deemed an original, but all of which
shall constitute one and the same instrument.
