ATTENTION:        ANDREW BURGIN

Dear Sir:

RE:      AMENDED STANDSTILL AGREEMENT

This letter is intended to reflect our recent discussions and, when executed and
delivered by each of us, will constitute a binding agreement (the "Amended
Standstill Agreement") between Ivanhoe Energy Inc. ("Ivanhoe") and Linyi
Holdings Limited. ("Linyi") wherein Linyi will refrain from demanding payment of
the Principal Amount of the Loan under the Amended and Restated Convertible Loan
Agreement between the parties dated August 4, 1999 (the "Loan Agreement") and
the associated Convertible Note (the "Convertible Note") issued by Ivanhoe to
Linyi dated August 4, 1999. The terms of the Loan Agreement and the Convertible
Note were amended by a Standstill Agreement between Ivanhoe and Linyi dated
October 29, 2002 (the "Original Standstill Agreement"). A copy of the Original
Standstill Agreement is attached to this Letter.

We confirm the terms of our Amended Standstill Agreement as follows:

1.    INTERPRETATION

      Terms denoted with initial capital letters and not otherwise defined
      herein have the meanings assigned to them in the Loan Agreement.

2.    STANDSTILL

      Linyi hereby agrees that it will not, under any circumstances, demand
      payment of the Principal Amount under the Loan Agreement and the
      Convertible Note before the close of business on December 27, 2003. The
      Agreement of Linyi hereunder not to demand payment of the Principal Amount
      does not affect its rights with respect to accrued and unpaid interest,
      and Linyi may continue to demand payment of any accrued and unpaid
<PAGE>
                                     - 2 -

      interest on the Principal Amount in accordance with the terms of the Loan
      Agreement and the Convertible Note.

3.    CONSIDERATION

      In consideration of Linyi's forbearance in demanding payment under the
      Loan Agreement and the Convertible Note, Ivanhoe hereby grants to Linyi an
      option (the "Option") to convert all or any part of the Principal Amount
      and all accrued and unpaid interest up until December 27, 2003 into common
      shares of Ivanhoe ("Common Shares"), in whole or in part at a deemed issue
      price of US$0.50 per Common Share (the "Conversion Price"). The Option
      will be exercisable commencing on the date hereof and ending on December
      27, 2003 (the "Option Period"). Linyi may exercise the Option at any time
      during the Option Period by delivering notice in writing to Ivanhoe to
      convert all or any part of the Principal amount and accrued and unpaid
      interest until December 27, 2003. Upon receipt of notice of exercise of
      the Option, Ivanhoe will take all steps necessary to issue the appropriate
      number of Common Shares to, or to the direction of, Linyi, and will
      deliver to Linyi share certificates representing such Common Shares. Upon
      delivery of the share certificates to Linyi, Ivanhoe will be deemed to
      have repaid the amount of the Principal Amount and/or accrued and unpaid
      interest which is equal to the Option Price.

      Linyi acknowledges that any Common Shares issued to Linyi hereunder will
      be subject to restrictions on resale in the United States and Canada and
      that certificates representing such Common Shares may be inscribed with
      legends describing such restrictions.

4.    ADJUSTMENT

      The number of Common Shares issuable to the Linyi upon any conversion of
      the outstanding Principal Amount and accrued and unpaid interest in
      respect thereof, will be subject to adjustment as follows:

      (a)   if the Common Shares are subdivided, consolidated or changed, the
            outstanding Principal Amount and accrued and unpaid interest in
            respect thereof, will be convertible at the Option Price into that
            number of common shares or other class or kind of securities of
            Ivanhoe as would have been held by Linyi following such subdivision,
            consolidation or change had Linyi effected such conversion
            immediately prior to the subdivision, consolidation or change; or

      (b)   in the event of any capital reorganization of Ivanhoe or
            reclassification or reclassifications of the Common Shares or in the
            event of any merger or amalgamation of Ivanhoe with or into any
            other corporation resulting in a reclassification of the Common
            Shares or a change of the Common Shares into other shares or
            securities or in the event of a transaction whereby all or
            substantially all of Ivanhoe's undertakings and assets become the
            property of another corporation, Linyi will thereafter acquire and
            accept, in lieu of the Common Shares immediately theretofore
            receivable upon the conversion of the outstanding Principal Amount
            and accrued and unpaid interest in respect thereof, the kind, class,
            series and amount of
<PAGE>
                                     - 3 -

            shares or other securities or property that Linyi would have been
            entitled to receive upon such capital reorganization,
            reclassification, merger, amalgamation or transaction if, on the
            effective date thereof, Linyi had been the holder of the number of
            Common Shares that Linyi would have acquired by the conversion of
            the outstanding Principal Amount and accrued and unpaid interest in
            respect thereof immediately before the effective date thereof. The
            subdivision or consolidation of Common Shares at any time
            outstanding into a greater or lesser number of Common Shares
            (whether with or without par value) will not be deemed to be a
            capital reorganization or a reclassification of the capital of
            Ivanhoe for the purposes of this section 4.

5.    APPROVALS

      Ivanhoe's obligations under this Standstill Agreement are subject to
      approval of the board of directors of Ivanhoe and approval of the
      transaction by the Toronto Stock Exchange.

6.    GENERAL

      terms and conditions:

      (a)   except as otherwise expressly provided herein, neither party may
            assign any right, title or interest in this Amended Standstill

            purported assignment without such consent will be void;

      (b)   this Amended Standstill Agreement constitutes the entire agreement
            between the parties with respect to the forbearance of the payment

            previous agreement, communication, expectation, negotiation,
            representation, warranty or understanding whether oral or written,

(20) hours per month of consulting services with respect to the Pilot Project

Thousand, Five Hundred and 00/100 ($7,500.00) Dollars, to analyze and evaluate
the market in the State of California for RTP(TM) upgraded products produced in
the amount of one thousand (1,000), three thousand (3,000) and ten thousand
(10,000) bpd.

         (c) Ivanhoe agrees that, at Ensyn's request, it will deliver petroleum
to the Alternate Site for a 24-hour test on the Pilot Project (i.e., up to 250
barrels) and, in such case, will pay, within thirty (30) days of Ensyn providing

         (d) If Ivanhoe delivers notice to Ensyn no later than the Notice
Deadline in the form attached hereto as Appendix "A" that Ivanhoe requires Ensyn
to operate the Pilot Project for a period of up to seven (7) days for the
Ivanhoe Testing of petroleum delivered to the Alternate Site by Ivanhoe
("Testing Notice") and Ivanhoe delivers such petroleum to the Alternate Site,
Ensyn shall perform such testing at a time reasonably agreed upon by the
Parties, but in no case later than June 30, 2004 unless the parties otherwise
agree in writing. In such case, Ivanhoe agrees to pay Ensyn within thirty (30)
days of Ensyn providing an invoice with respect thereto, an amount equal to all
Operating Costs of the Pilot Project during such period, as well as for the cost
of assays and evaluations for the products produced from such petroleum.
Provided that Ivanhoe gives Ensyn and the Owner reasonable notice and agrees to
ensure that persons visiting the Alternate Site adhere to the safety and other
reasonable requirements of Ensyn and the Owner, Ivanhoe has the right to visit
the Alternate Site during the Ivanhoe Testing and to visit the Alternate Site
with Third Parties with the prior approval of Ensyn, which approval shall not be
unreasonably withheld. It is understood and agreed that any Third Parties
visiting the Alternate Site at the request of Ivanhoe shall be required by
Ivanhoe to deliver to Ensyn a written acknowledgement of their familiarity with
the provisions of the Confidentiality Agreement and their agreement to be bound
by such provisions.

         (e) Subject to any confidentiality or nondisclosure agreements with
Third Parties, if Ivanhoe delivers the Testing Notice to Ensyn by the Notice
Deadline, during the period beginning on the date on which Ivanhoe provides the
Testing Notice to Ensyn ("Notice Date") and ending six months after the Ivanhoe
Results Date ("Project Data Period"), Ivanhoe shall have access to any and all
data with respect to the operation of the Pilot Project and the products
produced at the Pilot Project, including data with respect to the Ivanhoe
Testing ("Project Data") to enable Ivanhoe to understand the operation of the
Pilot Project and to analyze the economics of the Pilot Project and future
facilities at which the RTP(TM) technology may be utilized, including an Ivanhoe
Site. Notwithstanding the preceding sentence, it is understood and agreed that
Ivanhoe may share the results from the Ivanhoe Testing with Third Parties
provided that any Third Parties to whom Ivanhoe gives access to such data that
constitutes Confidential Information within the meaning of such term in the
Confidentiality Agreement shall be required by Ivanhoe to deliver to Ensyn a
written acknowledgement of their familiarity with the provisions of the
Confidentiality Agreement and their agreement to be bound by such provisions.

                                       4
<PAGE>
         (f) It is understood that prior to or during discussions with Third
Parties, at its own expense, Ivanhoe will have completed an analysis of the oil
proposed to be the raw material, the characteristics of the upgraded product
based on testing, the markets for the upgraded product, and transportation
studies regarding delivery of the products to the market ("Ivanhoe Analysis").
If Ivanhoe delivers the Testing Notice, as soon as it is available, but in no
case later than the end of the Project Data Period, Ivanhoe shall also deliver
the Ivanhoe Analysis to Ensyn, as well as data substantiating the initiation of
discussions with Third Parties, including information regarding, and
identification of, specific sites and the progress of such discussions ("Ivanhoe
Data").

         If Ivanhoe delivers the Testing Notice to Ensyn, Ivanhoe also agrees
that during the period from the Notice Date to the date that is one (1) year
after the Ivanhoe Results Date ("Information Period"), in addition to providing
Ensyn with the Ivanhoe Analysis and the Ivanhoe Data, Ivanhoe may obtain and
prepare information regarding the economics and other business considerations,
including preparing pro formas of the economics related to upgrading and selling
oil, with respect to certain oil fields or other areas in Peru and Oman that are
owned by others and which may be acquired by Ivanhoe ("Other Fields"), at which
the RTP(TM) could be utilized with the approval of Ensyn, ("Business
Information") so that the Parties can develop a business plan for such fields
("Business Plan"). The Business Plan shall also consider, if agreed to by the
Parties, the possibility that the Pilot Project could be installed and operated
at an Ivanhoe Site for an extended period of time or that the Technology would
be offered by Ensyn and Ivanhoe jointly to Third Parties for use at the Other
Fields, with Ivanhoe providing operating expertise and guidance to such Third
Parties. Such Third Parties may include foreign national or private oil
companies with which Ivanhoe has contacts and/or experience, provided that
Ensyn, in its sole discretion, is satisfied regarding the protection of the
Intellectual Property.

         It is recognized that Ensyn's basic terms for the installation and use
of the Technology are (i) Ensyn's cost in manufacturing the equipment (materials
and labor) plus 25%, and (ii) a one-time prepaid license fee ("Prepaid License
Fee") calculated as $500 per barrel of the maximum daily oil throughput capacity
of installed RTP(TM) equipment. However, if the Pilot Project is to be operated
by Ivanhoe on an Ivanhoe Site, the terms therefor will be negotiated by the
Parties. The parameters for the financial terms for the utilization of the
Technology at Other Fields shall be negotiated in the Business Plan. Such terms
include (i) responsibility for obtaining funding for the RTP(TM) equipment, (ii)
ownership of the facilities, (iii) the Prepaid License Fee, and (iv) an agreed
running royalty based upon the daily volume in barrels per day of treated oil
produced in a facility utilizing the Technology or some other or additional type
of participation arrangement. The Business Plan will also provide the basis for
Ivanhoe to purchase the RTP(TM) facilities for the Other Fields, which shall be
determined on a "most favored nations" basis for a period of time to be
negotiated by the Parties and based on the purchase price and license fees paid
for similar RTP(TM) facilities of Ensyn in the vicinity of the Other Fields.

         Notwithstanding any other provision of this Agreement, the Parties
understand and agree that no representations or guarantees are being made by
either of the Parties regarding the rights, obligations or intention of the
Parties to go forward with respect to any of the transactions analyzed and
discussed in this Section 2(f). Specifically, neither Party is obligated to
enter into binding agreements regarding the initial or permanent installation of
the Pilot Project, or the utilization of the Technology at the Other Fields.

         3. THIRD PARTY LIMITATIONS AND ACTIVITIES.

         (a) ENSYN. Ensyn agrees that, during the period from the Effective Date
through the Notice Deadline, it will not negotiate nor enter into business
transactions with Third Parties with respect to the development of RTP(TM)
projects in Peru and/or Oman or the sale of RTP(TM) equipment to be used in Peru
and/or Oman, provided that Ivanhoe has complied with the terms of this
Agreement.

                                       5
<PAGE>

         If Ivanhoe delivers the Testing Notice to Ensyn by the Notice Deadline,
then Ensyn agrees that it will not negotiate nor enter into business
transactions with Third Parties with respect to the development of RTP(TM)
projects in the country or countries for which the Testing Notice was delivered
(i.e., Peru and/or Oman) or the sale of RTP(TM) equipment to be used in the
country or countries for which the Testing Notice was delivered (i.e., Peru
and/or Oman) during the period from the Notice Deadline through the end of the
Information Period. However, it is understood and agreed that, subject to the
foregoing language with respect to the period prior to the end of Information
Period, Ensyn is, and shall be, free to negotiate and enter into business
transactions with respect to RTP(TM) projects outside of Peru and Oman and the
sale of RTP(TM) equipment to be used outside of Peru and Oman. Further, if
Ivanhoe does not deliver the Testing Notice to Ensyn by the Notice Deadline,
Ensyn shall be free to negotiate and enter into business transactions with
respect to RTP(TM) projects inside or outside of Peru and Oman and the sale of
RTP(TM) equipment to be used inside or outside of Peru and Oman without
restriction or limitation.

         If Ivanhoe delivers the Testing Notice to Ensyn by the Notice Deadline
and, by the end of the Information Period, (i) delivers the Ivanhoe Analysis,
the Ivanhoe Data and the Business Information to Ensyn, and (ii) identifies to
Ensyn the specific projects (i.e., working fields or undeveloped oil reserves)
in Peru and Oman at which it is interested in utilizing the Technology ("Areas
of Interest"), then Ensyn agrees that it will not negotiate nor enter into
business transactions with Third Parties with respect to the development of
RTP(TM) projects in the Areas of Interest in the country or countries for which
the Business Information was delivered (i.e., Peru and/or Oman) or the sale of
RTP(TM) equipment to be used in the Areas of Interest in the country or
countries for which the Business Information was delivered (i.e., Peru and/or
Oman) during the period from the end of the Information Period to the first
anniversary of the Information Period ("AI Exclusive Period"). However, it is
understood and agreed that, subject to the foregoing language with respect to
the Information Period, Ensyn is, and shall be, free to negotiate and enter into
business transactions with respect to RTP(TM) projects outside of the Areas of
Interest and the sale of RTP(TM) equipment to be used outside of the Areas of
Interest without restriction or limitation. Further, if Ivanhoe does not timely
perform the obligations described in the first sentence of this paragraph, Ensyn
shall be free to negotiate and enter into business transactions with respect to
RTP(TM) projects inside or outside of Peru and Oman and the sale of RTP(TM)
equipment to be used inside or outside of Peru and Oman without restriction or
limitation.

         Ivanhoe will have the option of extending the AI Exclusive Period for
an Area of Interest for a period of one (1) year by prepaying Ensyn 5% of the
Prepaid License Fee on a 10,000 barrel per day plant with $500/daily bbl of
capacity (i.e., $250,000 for each Area of Interest) ("Exclusivity Extension
Prepayment") at the end of the Information Period. Any Exclusivity Extension
Prepayment will be offset by Ivanhoe's out-of-pocket expenses, other than
salaries of Ivanhoe's employees, in pursuing opportunities for applying the
Technology in the Areas of Interest.

         Following the payment of the Exclusivity Extension Prepayment and the
resulting extension of the AI Exclusive Period in one or more of the Areas of
Interest, Ivanhoe will have the option of extending the AI Exclusive Period for
another year for such one or more Areas of Interest by prepaying 10% of the
Prepaid License Fee on a 10,000 barrel per day plant with $500/daily bbl of
capacity (i.e., $500,000 for each Area of Interest) at the end of the extended
AI Exclusive Period. Any such prepayment will be offset by Ivanhoe's
out-of-pocket expenses, other than expenses offset against the Exclusivity
Extension Prepayment and salaries of Ivanhoe's employees, in pursuing
opportunities for applying the Technology in the Areas of Interest. If Ivanhoe
is successful in going forward with an RTP(TM) project in the Areas of Interest
hereunder, Ensyn will have the option to participate in such project on a ground
floor for an interest equal to Ivanhoe's.

         If Ivanhoe does not pursue or is not successful in the Areas of
Interest during the AI Exclusive Period, including extensions thereof, Ensyn
will be free to pursue the application of the Technology in the Areas of
Interest by itself or with Third Parties, including negotiating and

                                       6
<PAGE>

entering into business transactions with respect to RTP(TM) projects in the
Areas of Interest and selling RTP(TM) equipment to be used in the Areas of
Interest. In such case, if Ivanhoe has paid the Exclusivity Extension Prepayment
and Ensyn is successful in negotiating with Third Parties an RTP(TM) project in
the Areas of Interest within four (4) years from the Effective Date, then
Ivanhoe will have the option to participate in such project on a ground floor
basis for an interest equal to Ensyn's.

        Subject to the foregoing limitations with respect to Peru and Oman and
with respect to the Areas of Interest, nothing in this Agreement shall prevent
Ensyn from conducting separate activities or joint activities with others or
entering into any arrangements with Third Parties without restriction or
limitation. It is further understood and agreed that, subject to the foregoing
limitations with respect to Peru and Oman and with respect to the Areas of
Interest, Ensyn has the right to engage in business and enter in transactions
with other companies, in California or elsewhere, without restriction or
limitation, including developing RTP(TM) projects and selling RTP(TM) equipment,
and that this Agreement does not, and shall not, restrict or limit such right
unless the Parties agree otherwise in other definitive agreements.

       (b) IVANHOE. Without limiting Ivanhoe's rights and obligations hereunder,
Ivanhoe shall not be obligated to exclusively use the Technology in its
operations, and shall be free to use, alternatively or additionally, technology
developed by Third Parties. It is also understood that Ivanhoe has complete
freedom to enter into transactions with other companies in California or
elsewhere, without restriction or limitation; regarding utilizing alternative
technology to RTP(TM).

         4. PROJECT DATA AND INTELLECTUAL PROPERTY. The Project Data shall be
and remain the property of Ensyn. Patent rights for any Intellectual Property
developed with respect to the Pilot Project or the RTP(TM) shall vest fully and
unconditionally in Ensyn, and Ensyn shall have the sole and exclusive right to
pursue patent protection to such Intellectual Property.

         5. CONFIDENTIALITY. Ivanhoe and Ensyn recognize that the carrying out
of the terms of this Agreement will require the exchange and transfer of
Confidential Information between the Parties, including Pilot Project operating
data or product related data, whether produced by one of the Parties or by a
Third Party; it is therefore agreed that the Confidential Information will be
considered to be Confidential Information supplied by the Parties pursuant to
the Confidentiality Agreement.

         6. AGREEMENTS WITH ALTERNATE SITE OWNER. The parties understand and
agree that this Agreement is subject to, and shall not interpreted in such
manner as contravenes, the provisions in any agreements between Ensyn and the
Owner with respect to the Pilot Project and the data therefrom, including any
confidentiality or nondisclosure agreements or provisions and any provisions
regarding access to the Alternate Site. Ivanhoe acknowledges that,
notwithstanding any other provision of this Agreement, it understands that it is
intended that the Pilot Project shall be installed on the Alternate Site for no
more than eighteen (18) months and operated on the Alternate Site for no more
than 180 days.

         7. ARBITRATION.

         (a) DISPUTES OR DISAGREEMENTS. All disputes or disagreements between
the Parties arising under or in connection with this Agreement will be resolved
in accordance with this Section 7. The Parties shall attempt to resolve any
dispute or disagreement by face-to-face meetings prior to resorting to any
additional process.

         (b) MEDIATION. To the extent that any dispute or disagreement is not
resolved by face-to-face meetings within thirty (30) days, the Parties will use
all commercially reasonable efforts to resolve and finally settle all claims and
disputes referred to in Section 6(a) through mediation by an independent Third
Party mediator chosen by the disputing Parties. Each of the Parties agrees that
during any mediation process it will provide reasonable access to an officer

                                       7
<PAGE>

with requisite decision-making authority for and on its behalf. The mediation
process will be completed within thirty (30) days following a request for
mediation by any one of the Parties. Each Party will bear its own costs of the
mediation, except that costs of the mediator will be borne equally between the
Parties.

         (c) ARBITRATION. Any claim or dispute not resolved by mediation within
the time period prescribed in Section 7(b) will be settled by binding
arbitration in accordance with the following:

             (i)     an arbitration will be commenced by a Party giving a
                     written notice to the other Party containing a statement of
                     the issue in dispute, a description of the claim being made
                     and a statement that a dispute is being submitted to
                     arbitration. The arbitration will be held in Wilmington,
                     Delaware pursuant to the rules of the American Arbitration
                     Association before a single arbitrator who is knowledgeable
                     in the petroleum processing industry. The Parties will
                     appoint the arbitrator by agreement within fifteen (15)
                     Business Days after the notice commencing the arbitration,
                     failing which the arbitrator will be appointed by the
                     American Arbitration Association in Delaware upon
                     application by either Party. The arbitrator's decision and
                     award will be final and binding and may be entered in any
                     court having jurisdiction over the enforcement of such
                     award. The arbitrator will not have the power to award any
                     damages excluded by or in excess of any damage limitations
                     expressed in this Agreement or any subsequent written
                     agreement between the Parties. In order to prevent
                     irreparable harm, the arbitrator may grant temporary or
                     permanent injunctive or other equitable relief in
                     accordance with the rules of equity;

             (ii)    while the arbitrator will generally determine, in
                     accordance with the rules of the American Arbitration
                     Association, the procedure to be followed in connection
                     with an arbitration, the Parties agree that each will have
                     the right to carry out examinations in aid of discovery of,
                     and in respect of, each of the other Parties in connection
                     with such arbitrated dispute and such examination in aid of
                     discovery will be conducted pursuant to the rules of
                     Delaware's Court of Chancery as though such arbitration
                     proceeding were a litigation proceeding; and

             (iii)   in the final award, the arbitrator may award costs in
                     accordance with the rules of Delaware's Court of Chancery
                     as if the arbitration were a trial of a matter before such
                     court.
