If, at any time and from time to time until October 24, 2012, Ivanhoe is contemplating to, directly or indirectly, offer, sell, contract to sell, grant any option or right to purchase, or issue any Ivanhoe Shares or Ivanhoe Convertible Securities to any person other than a member of the Rio Tinto Group in any transaction (an “Equity Financing Transaction”) other than an Exempt Ivanhoe Share Transaction, Ivanhoe must give written notice (a “Financing Notice”) to Rio Tinto, identifying the contemplated form of the Equity Financing Transaction (e.g., prospectus offering or private placement) and the contemplated ultimate purchaser or purchasers (other than underwriters, agents and retail or de minimis purchasers) under the Equity Financing Transaction (e.g., a Strategic Purchaser), and offering the equity financing to Rio Tinto on such bona fide arm’s length terms and conditions as Ivanhoe may determine. Upon receiving a Financing Notice, Rio Tinto or, at its direction, another member of the Rio Tinto Group, will have the right (the “Right of First Offer”) to acquire all or, if Ivanhoe has not terminated the Strategic Purchaser Covenant or given written notice to Rio Tinto of its intention to terminate the Strategic Purchaser Covenant, part of the Ivanhoe Shares or Ivanhoe Convertible Securities specified in the Financing Notice for the cash consideration stipulated in the Financing Notice. Rio Tinto or, at its direction, another member of the Rio Tinto Group, may exercise the Right of First Offer by providing written notice to Ivanhoe within 30 days of receipt by Rio Tinto of the Financing Notice (the “Exercise Period”). If Rio Tinto or another member of the Rio Tinto Group, as applicable, exercises the Right of First Offer, then a binding agreement will exist between Rio Tinto or such other member of the Rio Tinto Group, as applicable, and Ivanhoe with respect to the Ivanhoe Shares or Ivanhoe Convertible Securities specified in the Financing Notice for the consideration stipulated in the Financing Notice, and on the terms and conditions therein contained. If the Right of First Offer is not exercised prior to the expiry of the Exercise Period, Ivanhoe will have the right for a period of 60 days following the Exercise Period (the “Closing Period”) to issue all, but not less than all, of the Ivanhoe Shares or Ivanhoe Convertible Securities specified in the Financing Notice to the person or persons named in the Financing Notice for cash consideration having a value equal to or higher than the value

-5-

Ivanhoe may only deliver one Financing Notice to Rio Tinto in any 90 day period. Ivanhoe not may deliver a written notice to terminate the Strategic Purchaser Covenant during the Exercise Period or the Closing Period. For greater certainty, Rio Tinto’s rights under Part 5 of the Private Placement Agreement will continue to apply if the Right of First Offer is not exercised.

19.		Until October 24, 2012, Ivanhoe will not, directly or indirectly, offer, sell, contract to sell, grant any option or right to purchase, or issue any Ivanhoe Shares or Ivanhoe Convertible Securities to a Strategic Purchaser if, following such acquisition, the Strategic Purchaser and all persons with whom the Strategic Purchaser is acting jointly or in concert, would beneficially own or exercise control or direction over, or be deemed, under Applicable Law, to beneficially own, or exercise control or direction over, more than five per cent (5%) of the then issued and outstanding Ivanhoe Shares (the “Strategic Purchaser Covenant”). Upon sixty (60) days prior written notice to Rio Tinto, Ivanhoe may terminate the Strategic Purchaser Covenant.
20.		If Ivanhoe has terminated the Strategic Purchaser Covenant or given written notice to Rio Tinto of its intention to terminate the Strategic Purchaser Covenant and, as a result of the exercise of the Right of First Offer, the Rio Tinto Group and all persons with whom the Rio Tinto Group is acting jointly or in concert, would beneficially own or exercise control or direction, or be deemed, under Applicable Law, to beneficially own, or exercise control or direction over, (assuming the conversion, exchange or exercise of all Ivanhoe Convertible Securities held by them and the completion of the acquisition of all Ivanhoe Shares or Ivanhoe Convertible Securities specified in the applicable Financing Notice) more than forty six and sixty five-hundredths per cent (46.65%) of the then issued and outstanding Ivanhoe Shares, Section 6.1 of the Private Placement Agreement will be deleted in its entirety and cease to be of any force and effect.
21.		If, at any time, the Rio Tinto Group and all persons with whom the Rio Tinto Group is acting jointly or in concert, would beneficially own or exercise control or direction, or be deemed, under Applicable Law, to beneficially own, or exercise control or direction over, (assuming the conversion, exchange or exercise of all Ivanhoe Convertible Securities held by them) more than forty six and sixty five-hundredths per cent (46.65%) of the then issued and outstanding Ivanhoe Shares, Sections 6.4 and 6.5 of the Private Placement Agreement shall not apply to the Transfer of any Ivanhoe Shares by any of them provided that after such Transfer the Rio Tinto Group and all persons with whom the Rio Tinto Group is acting jointly or in concert continue to beneficially own or exercise control or direction, or be deemed, under Applicable Law, to beneficially own, or exercise control or direction over, (assuming the conversion, exchange or exercise of all Ivanhoe Convertible Securities held by them) more than forty five per cent (45%) of the then issued and outstanding Ivanhoe Shares.
