Subject to the terms and conditions of this Agreement, on the First Closing Date, pursuant to the First Subscription Agreement, Kennecott will subscribe for and purchase and Entrée will issue and sell, 5,665,730 Units (the “First Tranche”) at a price of $2.20 per Unit. If the Ivanhoe Pre-emptive Right is exercised in connection with the Private Placement, then, subject to the terms and conditions of this Agreement, on the Second Closing Date, pursuant to the Second Subscription Agreement, Kennecott will subscribe for and purchase and Entrée will issue and sell

2.2

Each Unit will consist of one Common Share, one A Warrant and one B Warrant. Two A Warrants will entitle Kennecott to purchase one additional Common Share at a price of $2.75 for a period of two years. Two B Warrants will entitle Kennecott to purchase one additional Common Share at a price of $3.00 for a period of two years. The instruments representing the A Warrants and the B Warrants will be in a form mutually satisfactory to the parties, acting reasonably, and will reflect the foregoing terms together with such other terms as are customary in respect of similar convertible securities including, without limitation, terms providing for the adjustment of the number of Common Shares issuable upon the exercise of the A Warrants and B Warrants and the exercise prices upon the occurrence of certain specified corporate events.

2.3

The parties will enter into a separate subscription agreement immediately prior to the First Closing Date in respect of the First Tranche (the “First Subscription Agreement”) and, if applicable, immediately prior to the Second Closing Date in respect of the Second Tranche (the “Second Subscription Agreement”), in form and substance mutually satisfactory to the parties, acting reasonably, and containing such representations, warranties, covenants and acknowledgements as are customary in similar private placement transactions. Notwithstanding the foregoing, the parties acknowledge and agree that the substantive terms of the Private Placement are as provided in this Article 2 and that this Article 2 constitutes a legal, valid and binding agreement and not merely an “agreement to agree” with respect to the Private Placement.

2.4

If, at any time after the First Closing Date, Entrée offers to sell for cash, by way of a private placement or a public offering, any Common Shares or any securities convertible into or exchangeable for Common Shares (for greater certainty, other than (i) incentive stock options or Common Shares issued on the exercise thereof, (ii) warrants outstanding as at the date hereof to purchase Common Shares, (iii) Common Shares issued on the exercise of any warrants, or (iv) Units to Ivanhoe on the Second Closing Date) (“Cash Offer Securities”), Entrée will offer to Kennecott, at least 10 Business Days prior to the issuance of any such Cash Offer Securities, by

2.5

Kennecott’s rights under section 2.4 will terminate if:

(a)

the number of Common Shares held by Kennecott and its Affiliates (assuming the exercise of all securities held by Kennecott and its Affiliates which are convertible into or exchangeable for Common Shares but which have not actually been issued) ceases to represent at least 10% of Entrée’s issued and outstanding Common Shares; or

(b)

Kennecott fails to exercise its rights under section 2.4 to subscribe for and purchase the maximum number of Cash Offer Securities which it has the right to purchase thereunder (other than Cash Offer Securities that are securities convertible into or exchangeable for Common Shares) and, as a result of the issuance of Cash Offer Securities to parties other than Kennecott, Kennecott’s percentage holding of the issued and outstanding Common Shares of Entrée is reduced.

2.6

Kennecott will vote its Common Shares, at every meeting of the shareholders of Entrée and at every adjournment thereof after the First Closing Date, in the manner that the Entrée Board specifies with respect to:

(a)

fixing the number of directors to be elected;

(b)

the election of directors of Entrée;

(c)

the appointment and remuneration of the auditors of Entrée; and

(d)

the approval of any corporate incentive compensation plan or any amendment thereof, provided the compensation plan could not result at any time in the number of Common Shares reserved for issuance under the plan exceeding 20% of the issued and outstanding Common Shares.

2.7

Upon receipt of a Voting Notice given in accordance with section 2.6, Kennecott will execute and deliver to an individual designated by Entrée in the Voting Notice (“Entrée’s Designee”) a proxy entitling Entrée’s Designee to vote the Common Shares held by Kennecott at the meeting to which the Voting Notice relates in accordance with the instructions in the Voting Notice. Kennecott agrees not to revoke the proxy. In any situation where the Entrée Board would not be entitled under law or the rules of any applicable securities regulatory authority or stock exchange to give voting instructions to Kennecott or to vote the Common Shares held by Kennecott by proxy at a meeting of shareholders, Kennecott will, with respect to the matters set out in section 2.6, vote the Common Shares held by it in the manner recommended by Entrée in its communications to shareholders in respect of such matters.

2.8

The requirements of section 2.6 and section 2.7 will:

(a)

not apply for any meeting of the shareholders of Entrée if, at the time of the meeting:

(i)

the number of Common Shares held by Kennecott and its Affiliates represents less than 10% of Entrée’s issued and outstanding Common Shares (excluding, for greater certainty, any Common Shares issuable on the exercise of any securities held by Kennecott and its Affiliates which are convertible into or exchangeable for Common Shares but which have not actually been issued) at such time; or

(ii)

the number of Common Shares held by Kennecott and its Affiliates represents 40% or more of Entrée’s issued and outstanding Common Shares (excluding, for greater certainty, any Common Shares issuable on the exercise of any securities held by Kennecott and its Affiliates which are convertible into or exchangeable for Common Shares but which have not actually been issued) at such time; and

(b)

terminate on the fourth anniversary of the First Closing Date.

2.9

If at any time after the First Closing Date or from time to time thereafter Kennecott wishes to dispose of any of its Common Shares or any of its securities convertible into or exchangeable for Common Shares (collectively, the “Entrée Securities”), Kennecott will so advise Entrée in a written notice (the “Disposition Notice”) which specifies the Entrée Securities that Kennecott wishes to dispose of (the “Offered Securities”), the minimum price that Kennecott would be prepared to accept for the Offered Securities and any other terms and conditions of the disposition. If, within 15 days of its receipt of the Disposition Notice, Entrée notifies Kennecott in writing of the identities of one or more persons who will purchase all, but not less than all, of the Offered Securities at the price and on the terms and conditions specified in the Disposition Notice, Kennecott will sell the Offered Securities to those purchasers(s), provided the purchaser(s) provide evidence satisfactory to Kennecott, acting reasonably, of the purchaser(s)’ ability to pay for the Offered Securities and to satisfy the other terms and conditions for the disposition. The purchaser(s) and Kennecott shall use their reasonable commercial efforts to complete the transaction within 45 days of Entrée’s receipt of the Disposition Notice. If Entrée does not notify Kennecott of the identities of one or more purchaser(s) and provide evidence, satisfactory to Kennecott, acting reasonably, of each purchaser(s) ability to pay for the Offered Securities and to satisfy the other terms and conditions of the disposition by the end of the 15 day period following Entrée’s receipt of the Disposition Notice or if Kennecott, despite its reasonable commercial efforts, is unable to complete the sale transaction within the 45 day period following Entrée’s receipt of the Disposition Notice as a result of the failure of the proposed purchaser(s), then Kennecott may dispose of the Offered Securities to any third party purchaser(s) at a price and on terms no less favourable to Kennecott than those specified in the Disposition Notice. This section will apply again to the Offered Securities if a sale to a bona fide third party purchaser(s) is not completed within 105 days of Entrée’s receipt of the Disposition Notice.

2.10

Section 2.9 does not apply in the case of:

(a)

a disposition by Kennecott of Entrée Securities to an Affiliate of Kennecott, provided that such Affiliate agrees in writing to be bound by Kennecott’s obligations under this Agreement (in which case the Affiliate will also be entitled to Kennecott’s rights under this Agreement);

(b)

Kennecott depositing Entrée Securities pursuant to a take over bid for which a circular has been delivered to Entrée shareholders in accordance with applicable securities laws;

(c)

a corporate consolidation, reorganization, merger, amalgamation or arrangement involving Kennecott by which the entity resulting therefrom owns, directly or indirectly, all or substantially all of the assets of Kennecott and assumes, directly or indirectly, all of the liabilities of Kennecott including, without limitation,
