Yamana Gold Inc.

Notes to the pro forma consolidated financial statements

June 30, 2007

(Unaudited)

(Expressed in thousands of U.S. dollars, unless otherwise noted)

1. Basis of presentation

The unaudited pro forma consolidated financial statements have been prepared in connection with the proposed acquisitions of Meridian Gold Inc. (“Meridian”) and Northern Orion Resources Inc. (“Northern Orion”) by Yamana Gold Inc. (“Yamana”). The unaudited pro forma consolidated financial statements have been prepared for illustrative purposes only and give effect to the proposed transactions and recent acquisitions completed by Yamana pursuant to the assumptions described in Note 6 to these pro forma consolidated financial statements. The unaudited pro forma consolidated balance sheet as at June 30, 2007 gives effect to the proposed transactions by Yamana as if they had occurred as of June 30, 2007. The unaudited pro forma consolidated statements of operations for the six month period ended June 30, 2007 and for the year ended December 31, 2006 give effect to the proposed transactions and recent acquisitions completed by Yamana as if they were completed on January 1, 2006.

The pro forma consolidated financial statements are not necessarily indicative of the operating results or financial condition that would have been achieved if the proposed transaction had been completed on the dates or for the periods presented, nor do they purport to project the results of operations or financial position of the consolidated entities for any future period or as of any future date. The pro forma consolidated financial statements do not reflect any special items such as payments pursuant to change of control provisions or integration costs or operating synergies that may be incurred as a result of the acquisitions.

The pro forma adjustments and allocations of the purchase price for Northern Orion and Meridian are based in part on estimates of the fair value of assets acquired and liabilities to be assumed. The final purchase price allocations will be completed after asset and liability valuations are finalized as of the date of the completion of the acquisitions. In addition, the allocations of the purchase price for recently completed acquisitions by Yamana are based in part on preliminary estimates of the fair values of the respective assets acquired and liabilities assumed and are open for subsequent adjustment based on valuations to be completed at a later date. Any final adjustments may change the allocation of purchase price which could affect the fair value assigned to the assets and liabilities in these unaudited pro forma consolidated financial statements.

In preparing the unaudited pro forma consolidated balance sheet and the unaudited pro forma consolidated statements of operations, the following historical information, that was prepared in accordance with Canadian GAAP, was used:

(a) the unaudited consolidated balance sheet of Yamana as at June 30, 2007, and the unaudited consolidated statement of operations for the six month period ended June 30, 2007;

(b) the unaudited consolidated balance sheet of Northern Orion as at June 30, 2007, and the unaudited consolidated statement of operations for the six month period ended June 30, 2007;

(c) the unaudited consolidated balance sheet of Meridian as at June 30, 2007, and the unaudited consolidated statement of operations for the six month period ended June 30, 2007;

(d) the audited consolidated financial statements of Yamana for the year ended December 31, 2006;

(e) the audited consolidated financial statements of Northern Orion for the year ended December 31, 2006;

1. Basis of presentation (continued)

(f) the audited consolidated financial statements of Meridian for the year ended December 31, 2006;

(g) the unaudited consolidated statement of operations of Desert Sun Mining Corporation (“DSM”) for the period from January 1, 2006 to March 31, 2006; and

(h) the unaudited consolidated statement of operations of Viceroy Exploration Ltd. (“Viceroy”) for the period from January 1, 2006 to September 30, 2006.

The unaudited pro forma consolidated balance sheet and the unaudited pro forma consolidated statements of operations should be read in conjunction with the June 30, 2007 unaudited interim consolidated financial statements and the December 31, 2006 audited consolidated financial statements including the notes thereto, as listed above.

The accounting policies used in preparing the pro forma financial statements are set out in Yamana’s consolidated financial statements for the year ended December 31, 2006. While management believes that accounting policies of Northern Orion and recently acquired entities are consistent in all material respects, accounting policy differences may be identified upon consummation of the proposed acquisition. Management has not had the opportunity to assess the impact, if any, of Meridian accounting policy differences with those of Yamana. Accounting policy differences may be identified upon consummation of the proposed acquisition.

2. Conversion of historical financial statements to U.S. dollars

The unaudited pro forma consolidated financial statements are presented in U.S. dollars and, accordingly, Viceroy’s unaudited statement of operations for the nine months ended September 30, 2006 and for the period from October 1, 2006 to October 13, 2006, and DSM’s unaudited statement of operations for the three months ended March 31, 2006 were converted from Canadian dollars to U.S. dollars using the average exchange rate for each period.

The exchange rates used for conversion to U.S. dollars from Canadian dollars are as follows:

As at August 9, 2007	$	1.0527
Average for the nine months ended September 30, 2006	1.1327
Average for the period from October 1, 2006 to October 13, 2006	1.1277
Average for the three months ended March 31, 2006	1.1546

3. Acquisition of Meridian

On June 27, 2007, Yamana announced a proposal to acquire all the outstanding common shares of Meridian (the “Original Offer”). Under the Original Offer, the shareholders of Meridian were to receive 2.235 Yamana shares plus $2.94 (Cdn$3.15) in cash. Based on a volume adjusted share price of $11.39 (Cdn$12.19), determined with reference to the share price of Yamana common shares for the two days prior to, the day of, and the two days subsequent to the date of announcement, the purchase price equates to total consideration of $28.40 (Cdn$30.39) per share. On August 13, 2007, Yamana announced an amended offer (the “Amended Offer”) to acquire all the outstanding shares of Meridian. Under the Amended Offer the shareholders of Meridian will receive 2.235 Yamana shares plus $3.80 (Cdn$4.00) in cash. Based on a volume adjusted share price of $11.08 (Cdn$11.67) determined with reference to the share price of Yamana common shares for the three day period ended August 9, 2007, the purchase price equates to total consideration of $28.56 (Cdn$30.08) per share. As at June 30, 2007, there were 101,203,037 common shares of Meridian outstanding.

The business combination, if completed, will be accounted for as a purchase transaction with Yamana as the acquirer of Meridian. Yamana is not making an offer to acquire or substitute any options outstanding to acquire common shares of Meridian (“Meridian options”). For purposes of these pro forma financial statements it has been assumed that all Meridian options are exercised prior to the closing date and that Yamana will acquire the Meridian shares issued pursuant to the exercise of the Meridian options under the Offer.

The Company has estimated the fair value of Meridian’s assets and liabilities. As Yamana has not had access to information relative to the respective fair value of Meridian’s mineral property, plant and equipment, the allocation at this time is very preliminary in nature.

The Company expects the accounting for the acquisition to result in a significant amount of goodwill. Goodwill is the excess cost of the acquired company over the sum of the amounts assigned to assets acquired less liabilities assumed. Generally accepted accounting principles in the U.S. require that goodwill not be amortized, but instead allocated to a level within the reporting entity referred to as the reporting unit and tested for impairment, at least annually. There is currently diversity in the mining industry associated with certain aspects of the accounting for business combinations and related goodwill. This diversity includes how companies define Value Beyond Proven and Probable reserves (“VBPP”), what an appropriate reporting unit is and how goodwill is allocated among reporting units. The methods of allocating goodwill have included allocations primarily to a single exploration reporting unit and allocations among individual mine reporting units depending on the relevant circumstances. We understand the industry is also evaluating other methodologies for allocating goodwill. The method of allocating goodwill will likely have an impact on the amount and timing of any future goodwill impairment, if any. Yamana has not completed its determination of the combined company’s reporting units nor its method of allocating goodwill to those reporting units. The ultimate accounting for VBPP and goodwill may not be comparable to other companies within the mining industry.

3. Acquisition of Meridian (continued)

The allocation of the purchase price is based upon management’s preliminary estimates and certain assumptions with respect to the fair value increment associated with the assets to be acquired and the liabilities to be assumed. The actual fair values of the assets and liabilities will be determined as of the date of acquisition and may differ materially from the amounts disclosed above in the assumed pro forma purchase price allocation because of changes in fair values of the assets and liabilities to the date of the transaction, and as further analysis (including of identifiable intangible assets, for which no amounts have been estimated and included in the preliminary amounts shown above) is completed. Consequently, the actual allocation of the purchase price will likely result in different adjustments in the unaudited pro forma consolidated statements of operations. Following completion of the transaction, the earnings of the combined company will reflect the impact of purchase accounting adjustments, including the effect of changes in the cost bases of both tangible and identifiable intangible assets and liabilities on production costs and depreciation, depletion and amortization expense.

The fair value of the net assets of Meridian to be acquired pursuant to the Amended Offer will ultimately be determined after the closing of the transaction. The Company will complete a full and detailed valuation of the Meridian assets using an independent party. Therefore, it is likely that the fair values of assets and liabilities acquired will vary from those shown below and the differences may be material.

The preliminary purchase price allocation is subject to change and is summarized as follows:

Purchase of Meridian shares (226,188,788 Yamana common shares)	$	2,506,451
Yamana shares issuable on exercise of Meridian options (1,768,741 Yamana common shares)	19,600
Cash consideration (including cash of $3,007 payable due to exercise of Meridian options)	387,557
Estimated transaction costs	17,000
Purchase consideration	$	2,930,608

The purchase price was allocated as follows:

Net working capital acquired (including cash of $102.1 million)			$	213,891
Mineral property, plant and equipment
Producing	$	1,635,385
Non-producing	619,485		2,254,870
Other long-term assets			31,000
Long-term liabilities			(101,000		)
Future income tax liability			(708,469		)
Non-controlling interest			(15,300		)
Net identifiable assets			1,674,992
Excess of purchase price allocated to goodwill			1,255,616
			$	2,930,608

3. Acquisition of Meridian (continued)

For information purposes only, using a reference date of June 27, 2007, the date of the original announcement, Yamana’s share price was $12.15 (Cdn$13.02) per share, which equated to total consideration of $30.09 (Cdn$32.25) per Meridian common share.

4. Acquisition of Northern Orion

Also on June 27, 2007, Yamana announced that it had entered into a business combination arrangement to acquire all the outstanding common shares of Northern Orion. Under the proposed transaction, the shareholders of Northern Orion will receive 0.543 of a Yamana common share for each Northern Orion common share outstanding. As at June 30, 2007, there were 154,087,161 common shares of Northern Orion outstanding. The volume adjusted share price of Yamana common shares for the period of two days prior to the day of the announcement, the day of the announcement, and the two days after the date of the announcement was $11.39 (Cdn$12.19).

The business combination, if completed, will be accounted for as a purchase transaction, with Yamana as the acquirer of Northern Orion. Yamana will also exchange all outstanding options and share purchase warrants of Northern Orion for similar securities of Yamana which, for purposes of these pro forma consolidated financial statements, have been assumed to be at an exchange ratio of 0.543 and at a price equivalent to the original price divided by 0.543. The fair value of the net assets of Northern Orion to be acquired will ultimately be determined at the closing of the transaction. Therefore, it is likely that the fair values of assets and liabilities acquired will vary from those shown below and the differences may be material.

Yamana has estimated the fair value of Northern Orion’s interest in Minera Alumbrera Ltd. at $340,000 and the fair value of Northern Orion’s non-producing properties at $432,000. The remainder of the purchase price over the carrying value of the assets acquired and liabilities assumed of $421,955 has been assigned as goodwill.

4. Acquisition of Northern Orion (continued)

The allocation of the purchase price is based upon management’s preliminary estimates and certain assumptions with respect to the fair value increment associated with the assets to be acquired and the liabilities to be assumed. The actual fair values of the assets and liabilities will be determined as of the date of acquisition and may differ materially from the amounts disclosed above in the assumed pro forma purchase price allocation because of changes in fair values of the assets and liabilities to the date of the transaction, and as further analysis (including of identifiable intangible assets, for which no amounts have been estimated and included in the preliminary amounts shown above) is completed. Consequently, the actual allocation of the purchase price may result in different adjustments in the unaudited pro forma condensed combined statements of income. Following completion of the transaction, the earnings of the combined company will reflect the impact of purchase accounting adjustments, including the effect of changes in the cost bases of both tangible and identifiable intangible assets and liabilities on production costs and depreciation, depletion and amortization expense.

The preliminary purchase price allocation is subject to change and is summarized as follows:

Purchase of Northern Orion shares (83,669,328 Yamana common shares)	$	952,688
Fair value of options and warrants acquired	242,918
Estimated transaction costs	17,000
Purchase consideration	$	1,212,606

The purchase price was allocated as follows:

Net working capital acquired (including cash of $237.2 million)	$	237,984
Property plant and equipment, net	223
Mineral properties and other assets	432,186
Equity investment in Minera Alumbrera Ltd.	340,478
Long-term liabilities	(15,231		)
Future income tax liability	(204,989		)
Net identifiable assets	790,651
Excess of purchase price allocated to goodwill	421,955
	$	1,212,606

For information purposes only, using a reference date of June 27, 2007, the date of the original announcement, Yamana’s share price was $12.15 (Cdn$13.02) per share which equates to total consideration of $6.60 (Cdn$7.07) per Northern Orion common share.

5. Recent acquisition of DSM and Viceroy by Yamana

(a) Acquisition of DSM

On April 5, 2006, Yamana completed the acquisition of DSM which owns the Jacobina gold mine in the Bahia state of Brazil. Total consideration paid was approximately $632 million comprised of approximately 63.9 million common shares, transaction costs and substitution of issued options and share purchase warrants. Yamana exchanged all outstanding shares, options and share purchase warrants of DSM for similar securities of Yamana at an exchange ratio of 0.6 of a Yamana common share for 1 DSM common share or equivalent.

Yamana has consolidated the results of operations from the Jacobina mine from the date of acquisition.

The purchase price was calculated as follows:

Common shares issued to acquired 100% of DSM (63,746,381 Yamana common shares)	$	534,852
Fair value of options and warrants issued	92,658
Transaction costs	3,094
Shares issued for employee severance (174,068 common shares)	1,361
Purchase consideration	$	631,965

The purchase price was allocated as follows:

Net working capital acquired (including cash of $18.1 million)	$	26,944
Property plant and equipment, net	37,792
Mineral properties and other assets	665,867
Other assets	3,548
Silicosis liability	(17,154		)
Long-term liabilities	(6,954		)
Future income tax liability	(133,078		)
Net identifiable assets	576,965
Residual purchase price allocated to goodwill	55,000
	$	631,965

As a result of this acquisition, the unaudited pro forma consolidated statements of operations for the year ended December 31, 2006 have been adjusted to include operations of DSM for the three month period ended March 31, 2006.

5. Recent acquisition of DSM and Viceroy by Yamana (continued)

(b) Acquisition of Viceroy

On October 14, 2006, the Company acquired approximately 95% of the outstanding common shares of Viceroy. The Company offered Viceroy shareholders 0.97 of a Yamana common share for each Viceroy common share. Subsequently, the Company commenced and completed the compulsory acquisition of the remaining Viceroy common shares not already owned at the same ratio of 0.97 of a Yamana common share for each Viceroy common share. Yamana exchanged all outstanding shares, options and share purchase warrants of Viceroy for similar securities of Yamana at an exchange ratio of 0.97 of a Yamana common share for 1 Viceroy common share or equivalent. Total consideration paid was approximately $549.1 million. Yamana has consolidated the results of operations from October 13, 2006.

The business combination was accounted for as a purchase transaction with Yamana as acquirer of Viceroy. The preliminary purchase price allocation is subject to change and is summarized as follows:

Purchase of Viceroy shares (52,542,397 Yamana common shares)	$	509,842
Fair value of options and warrants issued	35,230
Estimated transaction costs	4,075
Purchase consideration	$	549,147

The purchase price was allocated as follows:

Net working capital acquired	$	53,881
Property plant and equipment, net	1,666
Mineral properties	661,094
Other assets	2,794
Future income tax liability	(170,288		)
	$	549,147

6. Effect of transactions on the consolidated pro forma financial statements

The pro forma consolidated financial statements incorporate the following pro forma assumptions:

(a) Meridian assumptions

(i) The assumption that Yamana acquires 100% of the outstanding common shares of Meridian as a result of the Amended Offer. As per Note 3, this gives rise to an increase to fair value and related future income tax liabilities as follows:

Mineral property, plant and equipment	$	1,956,770
Goodwill	1,255,616
Future income tax liabilities	(684,869		)
	2,527,517
Book value of assets	403,091
Total purchase consideration	$	2,930,608

(ii) The assumption that all of the stock options of Meridian that were outstanding are exercised and converted into Meridian common shares for proceeds of $11,491, which are acquired by Yamana pursuant to the Amended Offer;

(iii) The pro forma consolidated financial statements include information from the financial statements of Meridian as at June 30, 2007 and for the six month period ended June 30, 2007 and the year ended December 31, 2006. It has been assumed that asset classifications are consistent with those used by Yamana in their presentation and that Meridian’s accounting policies conform to those of Yamana;

(iv) These pro forma adjustments eliminate the historical equity accounts of Meridian;

(v) This pro forma adjustment reflects the issuance of 228.0 million shares of Yamana for $2,526,051 in connection with the Amended Offer. This includes the shares issuable in connection with the assumed exercise of Meridian stock options;

(vi) This assumption provides for the recording of expenses of the transaction totaling $17 million;

6. Effect of transactions on the consolidated pro forma financial statements (continued)

(a) Meridian assumptions (continued)

(vii) This pro forma adjustment represents the estimated increase to depreciation, depletion and amortization expense (Six months to June 30, 2007 - $13,300: Year Ended December 31, 2006 - $30,500) associated with the preliminary fair value adjustment of approximately $1.4 billion allocated to mineral property, plant and equipment. Yamana has not completed an assessment of the fair values of assets and liabilities and the related business integration plans and synergies. The ultimate purchase price allocation will include possible adjustments to the fair values of depreciable tangible assets, proven and probable reserves, reserves related to current development projects, value beyond proven and probable reserves (referred to in this document as VBPP) and intangible assets after a full review has been completed. The concept of VBPP is described in Financial Accounting Standards Board Emerging Issue Task Force Issue No. 04-3 (“EITF 04-3”) and has been interpreted differently by mining companies. Our preliminary adjustment to plant, equipment and development costs, as discussed below, includes VBPP attributable to mineralized material that Yamana believes could be brought into production should market conditions warrant. Mineralized material is a mineralized body that has been delineated by appropriately spaced drilling and/or underground sampling to support reported tonnage and average grade of metals. Such a deposit may not qualify as proven and probable reserves until legal and economic feasibility are concluded based upon a comprehensive evaluation of unit costs, grade, recoveries and other material factors. Our preliminary adjustments to mineral property, plant, equipment and development costs do not include adjustments attributable to inferred mineral resources or exploration potential referred to in the EITF 04-3 Working Group Report No. 1. We intend to allocate a portion of the purchase price to all VBPP, including inferred mineral resources and exploration potential, in accordance with EITF 04-3 after performing a more thorough analysis to determine the fair value of these assets.

The preliminary allocation of $1.4 billion to mineral property, plant, equipment and development costs is primarily based on a fair value assessment of estimated cash flows. Yamana has not completed an assessment of the fair values of assets and liabilities and the related business integration plans and synergies. The ultimate purchase price allocation will include possible adjustments to fair values of depreciable tangible assets, proven and probable reserves, reserves related to current development projects, mill and leach stockpiles, product inventories, VBPP and intangible assets after a full review has been completed.

For the purpose of preparing the unaudited pro forma consolidated statements of operations, Yamana assumed an average estimated remaining useful life of 16 years for the El Penon Mine and 7 years for the Minera Florida Mine, which was based on an analysis of publicly available information. A one-year change in the estimated useful life would have an approximate $6 million impact on the pro forma depreciation, depletion and amortization expense on an annual basis. Additionally, for each $100 million that the final fair value of property, plant, equipment and development costs differs from the pro forma fair value, related depreciation, depletion and amortization expense would increase or decrease by approximately $7 million annually, assuming a weighted average 15-year life; and

6. Effect of transactions on the consolidated pro forma financial statements (continued)

(a) Meridian assumptions (continued)

(viii) It has been assumed that Yamana drew down $400 million of a revolving line of credit in order to finance the $387 million cash component of the acquisition of Meridian. Interest expense has been recorded in the amount of $15 million and $30 million during the six month period ended June 30, 2007 and the year ended December 31, 2006 respectively. Interest expense has been provided at 7.5%, which approximates the current rate under the facility and amortization of debt issue costs. A 1/8% change to the effective interest rate would change the interest expense by $500.

(b) Northern Orion assumptions

(i) The assumption that Yamana acquires 100% of the outstanding common shares of Northern Orion as a result of the transaction. As per Note 4 this gives rise to an increase to fair value and related future income tax liabilities as follows:

Mineral properties	$	309,654
Investment in Minera Alumbrera Ltd. (“Alumbrera”)	240,000
Goodwill	421,955
Future income tax liabilities	(181,386		)
	790,223
Book value of assets	422,383
Total purchase consideration	$	1,212,606

(ii) These pro forma adjustments eliminate the historical equity accounts of Northern Orion;

(iii) This pro forma adjustment reflects the issuance of 83.7 million shares of Yamana for $952,688 in connection with the Offer;

(iv) The assumption that, as at June 27, 2007, 12,567,500 stock options and 56,571,850 share purchase warrants of Northern Orion were outstanding and were exchanged for 6,824,153 stock options and 30,718,515 share purchase warrants of Yamana with fair values of $35,403 and $207,515, respectively. We have assumed that all options vest immediately upon completion of the transaction;

(v) The cash component of the Northern Orion acquisition is approximately $200 (Cdn$0.001 per common share of Northern Orion) and has not been reflected in these pro forma financial statements.

(vi) This assumption provides for the recording of expenses of the transaction totaling $17 million;

(b) Northern Orion assumptions (continued)

(vii) This pro forma adjustment represents the estimated increase to amortization expense (Six months to June 30, 2007 - $13,300: Year ended December 31, 2006 - $30,500) associated with the preliminary fair value adjustment of approximately $240 million allocated to Alumbrera, resulting in a reduction to reported equity income. Fair value increases to non producing properties do not give rise to any pro forma earnings adjustment. Yamana has not completed an assessment of the fair values of assets and liabilities and the related business integration plans and synergies. The ultimate purchase price allocation will include possible adjustments to the fair values of Alumbrera, depreciable tangible assets, proven and probable reserves, reserves related to current development projects, value beyond proven and probable reserves and intangible assets after a full review has been completed. The concept of VBPP is described in Financial Accounting Standards Board Emerging Issue Task Force Issue No. 04-3 (“EITF 04-3”) and has been interpreted differently by mining companies. Our preliminary adjustment to plant, equipment and development costs, as discussed below, includes VBPP attributable to mineralized material that Yamana believes could be brought into production should market conditions warrant.

We intend to allocate a portion of the purchase price to all VBPP, including inferred mineral resources and exploration potential, in accordance with EITF 04-3 after performing a more thorough analysis to determine the fair value of these assets.

The preliminary allocation of $240 million to Alumbrera is primarily based on a fair value assessment of estimated cash flows. Yamana has not completed an assessment of the fair values of assets and liabilities and the related business integration plans and synergies. The ultimate purchase price allocation will include possible adjustments to fair values after a full review has been completed.

For the purpose of preparing the unaudited pro forma condensed combined statements of operations, Yamana assumed an estimated remaining useful life of 10 years for the Alumbrera Mine, which was based on an analysis of publicly available information. A one-year change in the estimated useful life would have an approximate $20 million impact on the pro forma equity accounted earnings on an annual basis. Additionally, for each $100 million that the final fair value of Alumbrera costs differs from the pro forma fair value, related equity accounted earnings would increase or decrease by approximately $10 million annually, assuming a 10-year life; and

(c) Viceroy and DSM assumptions

(i) Including operating expenses for Viceroy for the period from October 1 to October 13, 2006;

(ii) Depreciation, amortization and depletion expense

It is assumed that the addition to mineral properties related to the excess of the purchase price over the assets acquired of DSM would be amortized on a unit-of-production basis over the proven, probable and possible reserves. In relation to DSM, the additional amortization for year ended December 31, 2006 would be $2,371; and

(iii) Tax effect

The tax effect of the additional mineral property amortization of DSM above for the year ended December 31, 2006 would be a pro forma recovery of $806.

(d) Other assumptions

(i) Transaction costs of Northern Orion, estimated to be in the amount of $20 million, have been given effect in these pro forma financial statements. Yamana has no knowledge of the costs incurred by Meridian with respect to this transaction; and

(ii) The pro forma balance sheet reflects adjustments for future income taxes based on temporary differences between assigned values of assets and liabilities acquired and of estimated tax basis (Meridian - $684,869 and Northern Orion - $181,386). Adjustments to the pro forma statements of operations have an associated tax effect when it is appropriate. All tax effects have been calculated with reference to the statutory rate in effect during the current periods for which statement of operations is provided.

8. Differences in generally accepted accounting principles between Canada and the United States of America (continued)

Significant differences between Canadian GAAP pro forma information and US GAAP pro forma information reflect the undernoted.

(i) Mineral properties - exploration costs and depletion

Under Canadian GAAP, resource property acquisition costs and exploration costs may be deferred and amortized to the extent they meet certain criteria. Capitalized costs under Canadian GAAP are amortized on a unit-of-production basis based on proven, probable and possible reserves.

Under US GAAP, acquisition costs and exploration costs must be expensed as incurred unless the resource properties have proven and probable reserves at which time costs incurred to bring the mine into production are capitalized as development costs. Capitalized costs are then amortized on a unit-of-production basis based on proven and probable reserves. An additional depletion and exploration expense is required to be recognized under US GAAP.

(ii) Pre-operating costs

US GAAP requires pre-operating costs to be expensed as incurred. Canadian GAAP allows pre-operating costs to be capitalized until commercial production is established.

(iii) Investments

Under US GAAP, items such as unrealized gains and losses on investments classified as available for sale are required to be shown separately in the derivation of comprehensive income. Under US GAAP, investments classified as available for sale are carried at the quoted market values. Under Canadian GAAP, gains and losses on marketable equity securities are noted in the footnotes and recognized in the statement of operations only when the investment is sold.

(iv) Comprehensive loss

In May 1993, the FASB issued SFAS No. 115, Accounting for Certain Investments in Debt and Equity Securities (“SFAS No. 115”). Under SFAS No. 115, management determines the appropriate classification of investments in debt and equity securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Under SFAS No. 115, equity securities and long-term investments are classified as available-for-sale securities and accordingly, the Company is required to include the net unrealized holding gain or loss on these securities in other comprehensive income. SFAS No. 130, Reporting Comprehensive Income, establishes standards for the reporting and display of comprehensive income and its components (revenue, expenses, gains and losses) in a full set of general purpose financial statements.

8. Differences in generally accepted accounting principles between Canada and the United States of America (continued)

(v) Pension costs

In September 2006, the FASB issued FAS 158, Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, which requires the recognition in the Company’s financial statements the funding status of a benefit plan and that the plan assets and benefit obligations be measured as of the date of the employer’s fiscal year-end statement of financial position. Under FAS 158 the Company is required to recognize unamortized actuarial gains and losses, prior service cost and remaining transitional amounts not recognized under Canadian GAAP, with the offset to comprehensive income.

Management has not provided a reconciliation to US GAAP for the financial position at June 30, 2007 and the results of operations for the six month period ended June 30, 2007. The information required to complete the reconciliation is not available. In the opinion of management, the material variation in accounting principles, practices and methods at June 30, 2007 and for the six month period then ended would be consistent with those disclosed with respect to December 31, 2006. In addition, Yamana, Northern Orion and Meridian were required to adopt FIN No. 48, Accounting for Uncertainty in Tax Positions, an Interpretation of FASB Statement No. 109, with effect from January 1, 2007. Management cannot determine if adoption of FIN No. 48 will give rise to a significant or material Canadian-United States GAAP difference due to limited access to information as at the time of preparation of these pro forma financial statements.

INFORMATION NOT REQUIRED TO BE DELIVERED TO
OFFEREES OR PURCHASERS

INDEMNIFICATION

Under the CANADA BUSINESS CORPORATIONS ACT (the ”CBCA”), the Registrant may indemnify a present or former director or officer of the Registrant or another individual who acts or acted at the Registrant’s request as a director or officer, or an individual acting in a similar capacity, of another entity, against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by the individual in respect of any civil, criminal, administrative, investigative or other proceeding in which the individual is involved because of that association with the Registrant or other entity. The Registrant may not indemnify an individual unless the individual acted honestly and in good faith with a view to the best interests of the Registrant, or, as the case may be, to the best interests of the other entity for which the individual acted as a director or officer or in a similar capacity at the Registrant’s request and in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, the individual had reasonable grounds for believing that the conduct was lawful. The indemnification may be made in connection with a derivative action only with court approval. The aforementioned individuals are entitled to indemnification from the Registrant as a matter of right if they were not judged by the court or other competent authority to have committed any fault or omitted to do anything that the individual ought to have done. The Registrant may advance moneys to the individual for the costs, charges and expenses of a proceeding; however, the individual shall repay the moneys if the individual does not fulfill the conditions set out above.

The by-laws of the Registrant provide that, subject to the limitations contained in the CBCA, the Registrant shall indemnify a director or officer, a former director or officer, or a person who acts or acted at the Registrant’s request as a director or officer of a body corporate of which the Registrant is or was a shareholder or creditor, and his heirs and legal representatives against all costs, charges and expenses, including an amount paid to settle an action or satisfy a judgment, reasonably incurred by him in respect of any civil, criminal or administrative action or proceeding to which he was made a party by reason of being or having been a director or officer of the corporation or such body corporate, if he acted honestly and in good faith with a view to the best interests of the corporation, and in the case of a criminal or administrative action or proceeding that is enforced by a monetary penalty, he had reasonable grounds for believing that his conduct was lawful.

The by-laws of the Registrant provide that the Registrant may, subject to the limitations contained in the CBCA, purchase, maintain, or participate in insurance for the benefit of any director, officer, or certain other persons, as such against any liability incurred by him in his capacity as a director or officer of the Registrant or as a director or officer of any body corporate where he acts or acted in that capacity at the Registrant’s request. The Registrant has purchased third party director and officer liability insurance.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the Registrant pursuant to the foregoing provisions, the Registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable.

EXHIBITS

The exhibit list has been updated to include the following exhibits as part of this Amendment No. 2 to the Registrant’s Registration Statement on Form F-10:
