BACK-IN RIGHTS

2.1 Exercise of Back-In Rights

	(a)		Talisman will have the right (the “Back-In Rights”), exercisable once per each Lease by notice in writing to Ivanhoe, to acquire up to a 20% undivided interest in each of the Lease 6 Assets and the Lease 10 Assets, and up to a 15% undivided interest in the Lease 50 Assets, until the date that is three (3) years following the date hereof. In the written notice Talisman shall specify which of the Assets it wishes to acquire, the percentage undivided interest(s) it wishes to acquire therein, and the Deemed Costs applicable to each of the Lease 6 Assets, the Lease 10 Assets and/or the Lease 50 Assets, as applicable. In this regard, the Deemed Costs for the applicable Assets shall be as set forth in the Deemed Costs Statement provided pursuant to clause 2.1(b)(i), or if an arbitrator renders a decision in connection therewith, as set forth in the arbitrator’s decision; there shall be no adjustments in connection with the Deemed Costs pursuant to the Pro Forma Conveyance Agreement. The effective date of each acquisition shall be the date of the applicable Deemed Cost Statement, provided that the Deemed Cost Statement shall remain valid and binding for a period of ninety (90) days from the date of issuance thereof or the date an arbitration decision is rendered in connection therewith, whichever is later. In order for Talisman to exercise its Back-In Rights there must be a valid and binding Deemed Cost Statement then in effect.
	(b)		In connection with the potential exercise of the Back-In Rights, Ivanhoe shall:

(i)

from time to time within thirty (30) days of a request therefor from Talisman (which request shall not be made by Talisman more than once per calendar quarter), provide to Talisman a detailed written summary of the Deemed Costs (the “Deemed Costs Statement”) incurred by Ivanhoe respecting the Lease 6 Assets, the Lease 10 Assets and/or the Lease 50 Assets between the date hereof and the date of such statement. Talisman may audit Ivanhoe’s records and supporting documentation relating to the Deemed Costs and the Deemed Costs Statement and the Assets in question, upon request. Ivanhoe shall respond in writing to any claim of

			discrepancy within ten (10) days of receipt of such claim. If Ivanhoe agrees with the claim, evidence of the adjustment shall accompany the response. If Ivanhoe disagrees with the claim, a detailed response with the relevant explanation shall be submitted to Talisman. If the Parties still do not agree, the matter shall be immediately resolved pursuant to arbitration in accordance with Article 3. For greater certaintly, Talisman shall not be required or obligated to exercise its Back-In Rights as a result of requesting a Deemed Cost Statement; and
	(ii)		from time to time within thirty (30) days of a request therefor from Talisman (which request shall not be made by Talisman more than once per calendar quarter), and for such period thereafter as Talisman may reasonably require, make the Assets available to Talisman so that Talisman can conduct a due diligence review of them, including a review of title to the Assets, the environmental condition of the Assets, the condition of any tangible property comprising the Assets, and the terms and conditions of any documents, licenses and agreements forming part of or relating to the Assets.

2.2 Pro Forma Conveyance Agreement

	(a)		The conveyance of the Lease 6 Assets, the Lease 10 Assets and the Lease 50 Assets shall occur in accordance with the Pro Forma Conveyance Agreement. In connection with such conveyance, the representations and warranties set forth in the Pro Forma Conveyance Agreement shall be updated to accurately reflect the current status of the parties, the assets and operations in respect thereof, having regard to the covenants in clause 2.5. The purchase price for the Lease 6 Assets, the Lease 10 Assets or the Lease 50 Assets, as the case may be, shall be the applicable Deemed Costs as determined pursuant to clause 2.1, multiplied by the applicable percentage (if any) set forth in clause 2.2(b), and further multiplied by the undivided percentage interest being acquired by Talisman in the Assets in question. Talisman shall prepare a copy of the Pro Forma Conveyance Agreement within thirty five (35) days of delivering the exercise notice in accordance with clause 2.1(a), and closing shall occur thereunder within five (5) days of such delivery, subject to clause 2.2(c). Any disputes respecting the terms of the Pro Forma Conveyance Agreement shall be resolved pursuant to arbitration in accordance with Article 3.
	(b)		If the Back-In Right is exercised in respect of one or more of the Lease 6 Assets, the Lease 10 Assets or the Lease 50 Assets during:

	(i)		the first year following the date hereof, Ivanhoe’s Deemed Cost shall not be multiplied by any further percentage;
	(ii)		the second year following the date hereof, Ivanhoe’s Deemed Cost respecting the Assets being acquired shall be multiplied by 150%; and

(iii)

the third year following the date hereof, Ivanhoe’s Deemed Cost respecting the Assets being acquired shall be multiplied by 200%.

(c)

Within three (3) days of receiving a notice pursuant to clause 2.1(a) in respect of the Lease 50 Assets, Ivanhoe shall issue a notice of right of first refusal and request for consent to each counterparty under the JOA, with the ascribed value thereunder being the purchase price as determined pursuant to clause 2.2(a).

2.3 Payment of the Purchase Price

The required payment from Talisman in connection with any exercise of the Back-In Rights shall be effected by:

	(a)		first, reducing the amount (if any) outstanding under the 2008 Note; and
	(b)		thereafter, at the election of Talisman, by way of cash payment or reduction of the amount outstanding under the Convertible Note. Talisman shall make such election concurrently with the exercise of the Back-In Right pursuant to clause 2.1.

2.4 Lease 50

The Parties acknowledge and confirm that:

	(a)		as at the date hereof the holder of the right of first refusal arising under the JOA by virtue of the Asset Transfer Agreement has exercised that right of first refusal; and
	(b)		this Agreement shall apply to the Lease 50 Assets only if Lease 50 is not conveyed to the right of first refusal holder and Ivanhoe thereafter acquires such lease, as contemplated in clause 4.1(a) of the Asset Transfer Agreement.

2.5 Covenants

During the period Talisman has the right to exercise the Back-In Rights pursuant to this Agreement (including until the last Pro Forma Conveyance Agreement is executed pursuant to this Agreement) Ivanhoe shall:

(a)

cause the Lease 6 Assets, the Lease 10 Assets and, to the extent applicable, the Lease 50 Assets, to be operated and maintained, in accordance with and subject to the applicable title and operating documents, applicable Regulations (as defined in the Pro Forma Conveyance Agreement) and generally accepted oil and gas industry practices in the province of Alberta, and shall not encumber the Assets with any additional royalties, adverse claims or interests that may have a material adverse effect on the value thereof;

	(b)		not do any act or thing, or omit to do any act or thing, whereby the representations and warranties set forth in clauses 9.1(b), 9.1(c) and 9.1(d) in the Pro Forma Conveyance Agreement would not be true and correct in all material respects;
	(c)		not grant any Right of First Refusal (as such term is defined in the Pro Forma Conveyance Agreement) in the Assets to the extent such Right of First Refusal would prevent Talisman from acquiring up to a 20% undivided interest in each of the Lease 6 Assets and the Lease 10 Assets, and up to a 15% undivided interest in the Lease 50 Assets as contemplated herein;
	(d)		not enter into any production sales contracts relating to the Assets that cannot be terminated on 90 days notice or less without penalty; and
	(e)		not grant any Security Interest (as such term is defined in the Pro Forma Conveyance Agreement) in the Assets unless such Security Interests can be discharged (or otherwise confirmed, to the satisfaction of Talisman, not to charge the interest of Talisman) upon the request or at the direction of Talisman as regards the interests Talisman may acquire in the Assets pursuant to this Agreement.

2.6 Operating Agreement

If there is no operating agreement (other than an agreement between Ivanhoe and any Affiliates thereof) applicable to any of the Assets in respect of which Talisman is exercising its Back-In Rights as at the date of such exercise, the Parties shall use their commercially reasonable efforts to enter into an operating agreement (for those Assets) the terms of which are acceptable to both Parties within ninety (90) days after the Pro Forma Conveyance Agreement is executed and delivered in connection with such exercise, failing which an operating agreement that is in the form of the JOA shall be deemed to govern those Assets upon the expiry of the ninety (90) day period.
