1.4	Time of Essence

Time shall be of the essence of this Agreement.

This Agreement shall be interpreted and enforced in accordance with, and the respective rights and obligations of the Parties shall be governed by, the laws of the State of New York without giving effect to the conflict of laws provisions thereof to the extent such principles or rules would require or permit the application of the laws of any jurisdiction other than those of the State of New York.

Each of the Parties irrevocably and unconditionally (i) submits to the exclusive jurisdiction of the Courts of the State of New York over any action or proceeding arising out of or relating to this Agreement, (ii) waives any objection that it might otherwise be entitled to assert to the jurisdiction of such courts, and (iii) agrees not to assert that such courts are not a convenient forum for the determination of any such action or proceeding.

If any provision of this Agreement is determined by a court of competent jurisdiction to be invalid, illegal or unenforceable in any respect, all other provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party hereto.  Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the Parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties hereto as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the extent possible.

The Investor shall not, directly or indirectly, whether alone or jointly or in concert with any other Person, without the prior written consent of the Board, (i) for so long as the Investor Percentage is equal to or greater than 5%; (ii) until the Parties otherwise agree in writing; or (iii) until the completion of a Fundamental Change:

For the avoidance of doubt, if the Investor Percentage drops below 5% and then goes back to 5% or greater in a single transaction or a series of related transactions, the restrictions of this Section 2.1 shall be reinstated.

The Investor covenants and agrees with the Company that: (i) for so long as the Investor Percentage is equal to or greater than 5%; (ii) until the Parties otherwise agree in writing; or (iii) until the completion of a Fundamental Change:

Furthermore, upon public announcement of, commencement of, or an intention to commence, an unsolicited bid or public announcement by the Company that it has agreed (or intends to agree) to any other Change of Control transaction described above in this Section 3.1, the Investor agrees that it shall not transfer any of the Debentures or Common Shares held by it (other than to an Affiliate of the Investor, as certified by the Investor and where such Affiliate agrees in writing to be bound by this Agreement as an “Investor”).  For the avoidance of doubt, if the Investor Percentage drops below 5% and then goes back to 5% or greater in a single transaction or a series of related transactions, the restrictions of this Section 3.1 shall be reinstated.

In situations not involving a Change of Control, the Investor covenants and agrees with the Company that: (i) for so long as the Investor Percentage is equal to or greater than 5%; (ii) until the Parties otherwise agree in writing; or (iii) until the completion of a Fundamental Change, it will either: (a) vote any and all Common Shares it holds, and to the extent it is afforded a voting right, the Debentures, on each matter that may come before the shareholders of the Company in the manner recommended by the Board to the shareholders of the Company or (b) not vote, in respect of such matter, any and all Common Shares it holds.  For the avoidance of doubt, if the Investor Percentage drops below 5% and then goes back to 5% or greater in a single transaction or a series of related transactions, the restrictions of this Section 3.2 shall be reinstated.

Without the prior written consent of the Company, the Investor covenants and agrees with the Company that, (i) for so long as the Investor Percentage is equal to or greater than 5%; (ii) until the Parties otherwise agree in writing; or (iii) until the completion of a Fundamental Change, it shall not, directly or indirectly, sell or transfer (in a single transaction or series of transactions within a 30 day period) any Common Shares held by it or over which it exercises control or direction, representing more than 0.5% of the outstanding Common Shares then outstanding (on a non-diluted basis) without first notifying the Company in writing of the number of Common Shares proposed to be sold and the price at which it desires to sell such Common Shares (which price for greater certainty, may be, or may be determined with reference to, a market price of the Common Shares on the date of sale) and the Company will have seven days following its receipt of the notice from the Investor to elect to identify one or more buyers of all or any portion of the Common Shares at the price offered by the Investor.  If the Company fails to identify a buyer within the seven day period, the Investor may only sell such Common Shares for a period of 30 days either (a) through a broad distribution, through the facilities of an exchange or trading system; or (b) to a United States financial institution (including brokerage) for its subsequent sale or distribution to others, provided that the Investor obtains a covenant of such financial institution not to knowingly sell or distribute such Common Shares to any entity identified by the Company within such seven day period as being an entity (including a mining company) that intends to, or is reasonably expected to, attempt to acquire the Company.  Notwithstanding the foregoing, the Investor is permitted to transfer any Common Shares held by it to an Affiliate of the Investor, as certified by the Investor and where such Affiliate agrees in writing to be bound by this Agreement as an “Investor”.  For the avoidance of doubt, if the Investor Percentage drops below 5% and then goes back to 5% or greater in a series of related transactions, the restrictions of this Section 4.1 shall be reinstated.

This Agreement shall terminate and all rights and obligations hereunder shall cease immediately upon the Parties agreeing in writing to terminate this Agreement.

The Parties agree that any breach of the terms of this Agreement by any Party would result in immediate and irreparable injury and damage to the other Parties which could not be adequately compensated by damages.  The Parties therefore also agree that in the event of any such breach or any anticipated or threatened breach by the defaulting Party, the other Parties shall be entitled to equitable relief, including by way of temporary or permanent injunction or specific performance, without having to prove damages, in addition to any other remedies (including damages) to which such other Parties may be entitled at law or in equity.
