THE ARRANGEMENT

2.1                            Binding Effect

This Plan of Arrangement will become effective at the Effective Time, and thereafter will be binding on each of the Securityholders, Tone Resources, Canadian Exchange Co. and US Gold.

2.2                            Arrangement

At the Effective Time, without any further act or formality, each of the events set out below shall occur and shall be deemed to occur in the following sequence:

(a)                                  each Tone Resources Share (other than Tone Resources Shares held by Canadian Exchange Co. and the Dissent Shares) shall be transferred to Canadian Exchange Co., free and clear of any Liens, and each Holder thereof shall be entitled to receive, in exchange therefor, 0.26 of an Exchangeable Share.  If the foregoing calculation results in a Tone Resources Share being exchangeable for a fraction of an Exchangeable Share, then the number of Exchangeable Shares to be issued to the Holder will be either rounded up (if the fractional interest is 0.5 or more) or down (if the fractional interest is less than 0.5) to the next whole number.  For rounding purposes, all Tone Resources Shares held by a Shareholder will be aggregated;

17

(b)                                 with respect to each Tone Resources Share transferred in accordance with Section 2.2(a):

(i)                                     the Holder thereof shall cease to be the registered holder of such share and the name of such Holder shall be removed from the register of Tone Resources Shares with respect to such Tone Resources Share as of the Effective Time;

(ii)                                  the certificate representing such Tone Resources Share shall be deemed to have been cancelled as of the Effective Time;

(iii)                               the Holder thereof shall be deemed to have executed and delivered all consents, releases, assignments and waivers, statutory or otherwise, required to transfer such Tone Resources Share to Canadian Exchange Co. in accordance with Section 2.2(a); and

(iv)                              Canadian Exchange Co. shall, and shall be deemed to be, the transferee of such share, free and clear of all Liens, and shall be entered in the register of Tone Resources Shares as the Holder thereof as of the Effective Time;

(c)                                  each Option shall be exchanged for an option of US Gold (a “Replacement Option”) to purchase that number of US Gold Shares equal to 0.26 times the number of Tone Resources Shares subject to such Option.  Such Replacement Option shall provide for an exercise price per US Gold Share equal to the exercise price per share of such Option immediately prior to the Effective Time divided by 0.26.  If the foregoing calculation results in a Replacement Option being exercisable for a fraction of a US Gold Share, then the number of US Gold Shares subject to such Replacement Option will be either rounded up (if the fractional interest is 0.5 or more) or down (if the fractional interest is less than 0.5) to the next whole number of US Gold Shares and the total exercise price for the Replacement Option will be increased or reduced accordingly.  The term to expiry, conditions to and manner of exercising, vesting schedule, if any, and all other terms and conditions of such Replacement Option will be unchanged, and any document or agreement previously evidencing such Option shall thereafter evidence and be deemed to evidence such Replacement Option; and

(d)                                 each Warrant shall, unless the holder thereof shall have entered into a Warrant Exchange Agreement with Canadian Exchange Co. prior to the Expiry Time, be exchanged for a warrant of Canadian Exchange Co. (a “Replacement Warrant”) to purchase that number of Exchangeable Shares equal to 0.26 times the number of Tone Resources Shares subject to such Warrant.  Such Replacement Warrant shall provide for an exercise price per Exchangeable Share equal to the exercise price per share of such Warrant immediately prior to the Effective Time divided by 0.26.  If the foregoing calculation results in a Replacement Warrant being exercisable for a fraction of an Exchangeable Share, then the number of Exchangeable Shares subject to such Replacement Warrant will be either rounded up (if the fractional interest is 0.5 or more) or down (if the fractional interest is less than 0.5) to the next whole number of Exchangeable Shares and the total exercise price for the Replacement Warrant will be increased or reduced accordingly.  The term to expiry, conditions to and manner of exercising and all other terms and conditions of such Replacement Warrant will be unchanged, and any document or agreement previously evidencing such Warrant shall thereafter evidence and be deemed to evidence such Replacement Warrant.

18

ARTICLE 3
DISSENT RIGHTS

3.1                            Rights of Dissent

A Holder may exercise the dissent rights (“Dissent Rights”) conferred by the Interim Order in connection with the Arrangement in the manner set out in Section 238 of the BCBCA, as modified by the Interim Order, provided that the Dissent Notice is received by Tone Resources by no later than 5:00 p.m. (Vancouver time) on the date which is two Business Days prior to the date of the Meeting.  Without limiting the generality of the foregoing, Holders who duly exercise such Dissent Rights and who are ultimately determined to be entitled to be paid fair value for their Tone Resources Shares shall be deemed to have transferred such Tone Resources Shares, as of the Effective Time, without any further act or formality, to Tone Resources in consideration of a payment of cash by Tone Resources equal to such fair value.  In no case shall Tone Resources or Canadian Exchange Co. be required to recognize such Holders as Shareholders at and after the Effective Time, and the names of such Holders shall be removed from the register of Tone Resources Shares as of the Effective Time.

3.2                            Rights of Dissenting Holders of Resources Shares

In the event that a Holder gives a Dissent Notice but is not entitled, for any reason, to be paid the fair value of the Tone Resources Shares in respect of which the Dissent Notice was given as contemplated in Section 242 of the BCBCA and the Interim Order, such Holder shall be deemed to have participated in the Arrangement on the same basis as a non-dissenting Shareholder.

ARTICLE 4  
DELIVERY OF SHARE CERTIFICATES

4.1                            Delivery to Registered Holders

4.1.1                        As soon as reasonably practicable after the later of (X) the Effective Date, and (Y) delivery to the Depositary of a duly completed Letter of Transmittal, together with the certificates representing Tone Resources Shares, Canadian Exchange Co. shall cause the Depositary:

(c)                                  if the Letter of Transmittal neither specifies an address nor contains a request as described in (b) above, to forward or cause to be forwarded by first class mail to the Tone Resources Shareholder at the address of the Tone Resources Shareholder as shown on the share register maintained by Tone Resources immediately prior to the Effective Time;

a share certificate representing the number of Exchangeable Shares issuable to such Shareholder hereunder in respect of the Tone Resources Shares described in such Letter of Transmittal, provided that in no event shall any holder of Tone Resources Shares be entitled to a fractional Exchangeable Share.

4.1.2                        As soon as reasonably practicable prior to Canadian Exchange Co. being required to make any delivery contemplated by Section 4.1 or Section 4.2, Canadian Exchange Co. will provide the Depositary with the certificates representing the Exchangeable Shares referred to therein, and such certificates shall be held in trust for the Shareholders and otherwise as contemplated in this Plan of Arrangement.

4.2                            Lost Certificates

If any certificate which immediately prior to the Effective Time represented Tone Resources Shares that were deemed to be transferred to Canadian Exchange Co. pursuant to Section 2.2(b) has been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Shareholder claiming such certificate to be lost, stolen or destroyed and the delivery of a duly completed Letter of Transmittal, in exchange for such lost, stolen or destroyed certificate, within 10 Business Days after the later of:

(ii)                                  if requested by the Shareholder in the Letter of Transmittal, to make available at the offices of the Depositary for pick up by the Shareholder; or

19

(iii)                             if the Letter of Transmittal neither specifies an address nor contains a request as described in (ii) above, to forward or cause to be forwarded by first class mail to the Shareholder at the address of the Shareholder as shown on the share register maintained by Tone Resources immediately prior to the Effective Time;a share certificate representing the number of Exchangeable Shares issuable to such Shareholder hereunder in respect of the Tone Resources Shares for which a duly completed Letter of Transmittal and the bond or other indemnity referred to below have been delivered to the Depositary pursuant to the provisions hereof.  A condition precedent to the delivery of any such share certificate or cheque shall be that the person entitled to the same shall give a bond reasonably satisfactory to Canadian Exchange Co. and the Depositary in such reasonable sum as Canadian Exchange Co. may direct or otherwise indemnify Canadian Exchange Co. and the Depositary in a manner reasonably satisfactory to them against any claim that may be made against either of them with respect to the certificate alleged to have been lost, stolen or destroyed.

4.3                            Extinction of Rights

If any Shareholder fails for any reason to deliver to the Depositary for cancellation the certificates formerly representing Tone Resources Shares (or an affidavit of loss and bond or other indemnity pursuant to Section 4.2) together with a duly completed Letter of Transmittal, on or before the sixth anniversary of the Effective Date, such Shareholder shall be deemed to have surrendered and forfeited to Canadian Exchange Co. any Exchangeable Shares held by the Depositary in trust for such Shareholder to which such Shareholder is entitled.  Subject to this Section 4.3, at and after the Effective Time, any certificate formerly representing Tone Resources Shares shall represent only the right to receive a certificate representing the Exchangeable Shares for which such Tone Resources Shares are exchanged pursuant to Section 2.2(a), provided that such certificates shall, on the sixth anniversary of the Effective Date, cease to represent a claim of any nature whatsoever, shall be deemed to have been surrendered to Canadian Exchange Co. and shall be cancelled.

4.4                            Withholding

Canadian Exchange Co., US Gold, Tone Resources and the Depositary shall be entitled to deduct and withhold from any consideration otherwise payable under this Plan of Arrangement to any Securityholder such amounts as Canadian Exchange Co., US Gold, Tone Resources or the Depositary is required or permitted to deduct and withhold with respect to such payment under the Income Tax Act (Canada) or any provision of provincial, local or foreign tax law, in each case as amended.  To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the relevant Securityholder in respect of which such deduction and withholding was made, provided that such withheld amounts are actually remitted to the appropriate taxing authority.  To the extent that the amount so required or permitted to be deducted or withheld from any payment to a relevant Securityholder exceeds the cash portion of the consideration, if any, otherwise payable to such Securityholder, Canadian Exchange Co., US Gold, Tone Resources and the Depositary are hereby authorized to sell or otherwise dispose of such portion of the consideration as is necessary to provide sufficient funds to Canadian Exchange Co., US Gold, Tone Resources or the Depositary to enable it to comply with such deduction or withholding requirement and Canadian Exchange Co., US Gold, Tone Resources or the Depositary shall remit to such Securityholder any unapplied balance of the net proceeds of such sale.
