Explanatory Note

This Amendment No.1 hereby amends the registration statement on Form 8-A (the “Registration Statement”) filed by Ivanhoe Mines Ltd. (“Ivanhoe”) with the U.S. Securities and Exchange Commission (the “SEC”) on April 5, 2010.

The Registration Statement is incorporated herein by reference. Item 1 of the Registration Statement is amended by adding the following:

Item 1. Description of Registrant’s Securities to be Registered

On April 22, 2010, the Board of Directors of Ivanhoe approved and adopted an Amended and Restated Shareholder Rights Plan Agreement (the “Amended Rights Plan”) to replace the Company’s Shareholder Rights Plan Agreement, dated April 5, 2010 (the “Original Rights Plan”) by and between Ivanhoe and CIBC Melon Trust Company, as Rights Agent (the “Rights Agent”).

The authorized amendments reflected in the Amended Rights Plan can be summarized as follows:

·       the definition of "Acquiring Person" has been revised to enable a person who becomes the beneficial owner of 20% or more of the common shares through a combination of listed provisions to acquire an additional 1% of Ivanhoe's shares without triggering the plan;

·       the definition of "Beneficial Ownership" has been revised to delete the reference to ownership by way of "Derivative Contracts";

·       the definition of "Exempt Acquisition" has been revised to cap the exemption for issuances under incentive plans and to modify the provision related to permitted treasury issuances; and

·       the shareholder approval provision has been revised to clarify that separate shareholder approvals of the plan will exclude both "Acquiring Persons" and "Grandfathered Persons".

The Amended Rights Plan currently is in effect, subject to confirmation through a vote of shareholders at Ivanhoe’s annual general and special meeting to be held on May 7, 2010. Capitalized terms used but not otherwise defined herein will have meanings given such terms in the Amended Rights Plan.  The foregoing description is only a summary of certain terms and conditions of the Amended Rights Plan and is qualified in its entirety by reference to the Amended Rights Plan, which is incorporated into this Registration Statement by reference as Exhibit 4.2.
