Unaudited Pro Forma Condensed Combined Financial Information

The following unaudited pro forma condensed combined financial information combines the historical consolidated financial statements of Paramount Gold and Silver Corp. (“Paramount”) and X-Cal Resources Ltd. (“X-Cal”) as adjusted for the Transaction, which is described further in the notes to unaudited pro forma condensed combined financial information. The acquisition of X-Cal by Paramount will be accounted for as a business combination under Accounting Standards Codification (“ASC”) 805, Business Combinations. For this purpose, Paramount will be deemed the accounting acquirer, and X-Cal will be deemed the accounting acquiree. The pre-acquisition combined financial statements of Paramount will be treated as the historical financial statements of the combined company.

Paramount has a fiscal year end of June 30, and X-Cal has a fiscal year end of March 31. As permitted by the U.S. Securities and Exchange Commission (“SEC”) rules and regulations, Paramount has combined the Paramount consolidated statement of operations for the year ended June 30, 2009 and the nine months ended March 31, 2010 with X-Cal’s combined statement of operations for the year ended March 31, 2009 and the nine months ended December 31, 2009, for purposes of the unaudited pro forma condensed combined financial statements.

The unaudited pro forma condensed combined statement of operations for the year ended June 30, 2009 and the nine months ended March 31, 2010 give effect to the Transaction as if it had occurred on July 1, 2008. The unaudited pro forma condensed combined balance sheet assumes that the Transaction was consummated on March 31, 2010 and combines Paramount’s historical consolidated balance sheet as of March 31, 2010 with X-Cal’s historical consolidated balance sheet as of March 31, 2010.

The unaudited pro forma condensed balance sheet and statement of operations of Paramount as of and for the nine months ended March 31, 2010 were derived from its unaudited consolidated financial statements as of March 31, 2010 (as filed on Form 10-Q/A with the SEC on November 5, 2010). The unaudited pro forma condensed combined statement of operations of Paramount for the year ended June 30, 2009 was derived from the audited consolidated financial statements of Paramount for the year ended June 30, 2009 (as filed on Form 10-K/A with the SEC on April 19, 2010).

The unaudited pro forma condensed balance sheet of X-Cal as at March 31, 2010 was derived from the audited consolidated balance sheet as at March 31, 2010 (as filed on SEDAR on June 29, 2010). The unaudited pro forma condensed consolidated statement of operations of X-Cal for the nine months ended December 31, 2009 were derived from its unaudited consolidated financial statements for the nine months ended December 31, 2009 (as filed on SEDAR on February 12, 2010). The unaudited pro forma condensed consolidated statement of operations of X-Cal for the year ended March 31, 2009 was derived from the audited consolidated financial statements of X-Cal for the year ended March 31, 2009 (as filed on SEDAR on June 26, 2009).

The pro forma adjustments are based upon available information, preliminary estimates and certain assumptions that Paramount believes are reasonable and are described in the accompanying notes to the unaudited pro forma condensed combined financial information. The unaudited pro forma condensed combined financial information does not take into account (i) any synergies or cost savings that may or are expected to occur as a result of the Transaction or (ii) any non-recurring cash or non-cash charges that Paramount may incur in connection with the Transaction, the level and timing of which cannot yet be determined. The unaudited pro forma condensed combined financial statements have been prepared in accordance with SEC rules and regulations.

The unaudited pro forma condensed combined financial information assumes that the acquisition would be accounted for using the acquisition method of accounting in accordance with ASC 805. The total purchase price has been preliminarily allocated based on available information and preliminary estimates and assumptions that management believes are reasonable. However, the allocation of purchase price has not been finalized and the actual adjustments to our financial statements upon closing of the acquisition transaction will depend on a number of factors, including additional information available and the net assets on the closing date of the Transaction. Accordingly, there can be no assurance that the final allocation of purchase price will not materially differ from the preliminary allocations reflected in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is provided for informational purposes only, is subject to a number of uncertainties and assumptions and does not purport to represent what the combined company’s actual performance or financial position would have been if the Transaction had occurred on the dates indicated and does not purport to indicate financial position or results of operations as of any future date or for any future date.

Please refer to the following information in conjunction with this unaudited pro forma condensed combined financial information: the accompanying notes to these unaudited pro forma condensed combined financial statements, Paramount’s and X-Cal’s historical financial statements and the accompanying notes thereto, “Management’s Discussion and Analysis” filed on SEDAR for X-Cal’s years ended March 31, 2009 and 2008 and for the nine months ended December 31, 2009 and 2008, from Paramount’s Annual Report on Form 10-K for the year ended June 30, 2009 and from Paramount’s Quarterly Report on Form 10-Q/A as of and for the nine months ended March 31, 2010.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

Note 1 - Description of the Transaction

On June 22, 2010, Paramount entered into an Arrangement Agreement (the “Agreement”) with X-Cal Resources Ltd. The Agreement provides that, upon the terms and subject to the conditions set forth in the Agreement, X-Cal will become a wholly owned subsidiary of Paramount.

Subject to the terms and conditions of the Agreement, which are subject to approval by the shareholders of X-Cal, at the effective time of the Agreement, (i) each common share of X-Cal issued and outstanding immediately prior to the effective time, will be exchanged for a common share of Paramount, on the basis of 8 common shares of X-Cal for 1 common share of Paramount (the “Exchange Ratio”), (ii) each warrant to purchase a common share of X-Cal outstanding immediately prior to the effective time (“X-Cal Warrant”), will be exchanged for 0.125 common stock purchase warrants of Paramount (“Paramount Warrant”), with each such Paramount Warrant having an exercise price equal to the quotient of (a) the exercise price per X-Cal Share subject to such X-Cal Warrant divided by (b) the Exchange Ratio, expiring at the end of the term of the relevant X-Cal warrant, and otherwise having the same terms and conditions as such X-Cal Warrant, (iii) each option to purchase a common share of X-Cal outstanding immediately prior to the effective time (“X-Cal Option”), will be terminated and in substation therefor, 0.125 stock options of Paramount (“Paramount Option”) will be issued under Paramount’s stock option plan to the persons who held X-Cal options prior to the effective time, per X-Cal option held, with each such Paramount Option having an exercise price equal to the quotient of (a) the exercise price per X-Cal Share subject to such X-Cal Option divided by (b) the Exchange Ratio, expiring at the end of the term of the relevant X-Cal Option (the “Transaction”).

Concurrently with the date of the Agreement, Paramount and X-Cal entered into an agreement providing for a loan in the amount of $1,100,000 to be made to X-Cal by Paramount in monthly advances (the “Loan”). The Loan shall be unsecured, and for so long as any amount remains outstanding under the Loan, X-Cal shall agree to not sell or encumber any of its interest in X-Cal’s mineral property interests, except as required for the repayment of the Loan.

In the event that the Agreement is terminated:

(i)	because X-Cal accepts, and enters into an agreement in respect of, a Superior Proposal (as defined in the Agreement) to the Agreement, the loan shall be repayable within ten business days, bearing interest from the date of the advance at a rate of 8% per annum;

(ii)	as a result of X-Cal shareholders failing to approve the Transaction, the loan shall be repayable within forty five days of the meeting of X-Cal shareholders; or

(iii)

for any reason other than as set out in (i) and (ii) above, the Loan shall be repayable on or before December 31, 2010, bearing interest from the date of the advance at a rate of 8% per annum.

In the event that the Loan is not repaid when due, the interest rate in default shall thereafter increase to an effective rate of 24% per annum.

Note 2 - Basis of Presentation

The unaudited pro forma condensed combined financial information has been prepared based on the historical financial information of Paramount and X-Cal giving effect to the Transaction and related adjustments described in these notes. Certain note disclosures normally included in the financial statements prepared in accordance with generally accepted accounting principles in the United States have been condensed or omitted as permitted by SEC rules and regulations.

X-Cal presents its financial statements in its functional currency of the Canadian Dollar. Paramount presents its financial statements in its functional currency of the U.S. Dollar. The historical financial statements of X-Cal, from which the unaudited consolidated combined pro forma financial statements have been derived, have been translated from the Canadian Dollar to the U.S. Dollar utilizing exchange rates follows:

Paramount Gold and Silver Corp.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

Balance sheet as at March 31, 2010	$ 0.98
Statement of operations for the nine months ended December 31, 2009		$ 0.90
Statement of operations for the year ended March 31, 2009		$ 0.88

The unaudited pro forma condensed combined financial information was prepared under existing U.S. GAAP standards, which are subject to change and interpretation.

This unaudited pro forma condensed combined financial information is not necessarily indicative of the results of operations that would have been achieved if the Transactions had actually taken place at the dates indicated and does not purport to be indicative of future position or operating results.

Note 3 - Accounting Policies

Upon consummation of the Agreement, Paramount will continue the review of X-Cal’s accounting policies. As a result of that review, Paramount may identify differences between the accounting policies of the two companies that, when conformed, could have a material impact on the combined financial statements. At this time, Paramount is not aware of any differences that would have a material impact on the combined financial statements, except as follows.

X-Cal prepares its financial statements in accordance with Canadian generally accepted accounting principles (“Canadian GAAP”). Under Canadian GAAP, acquisition and exploration expenditures on mineral properties, less recoveries in the pre-production stage, are deferred until such time as the properties are put into commercial production, sold, or become impaired. On the commencement of commercial production, the deferred costs are charged to operations on the unit-of-production method based upon estimated recoverable proven and probable reserves. General exploration expenditures are charged to operations in the period in which they are incurred.

Under U.S. GAAP, acquisition costs are capitalized, but exploration costs are not considered to have the characteristics of property, plant and equipment and, accordingly, are expensed prior to the company determining that economically proven and probable mineral reserves exist, after which all such costs are capitalized.

Set out below are the material adjustments to X-Cal’s mineral properties and deficit as at March 31, 2010, and to operating expenses for the nine months ended December 31, 2009 and the year ended March 31, 2009 in order to conform to U.S. GAAP:

Mineral properties	March 31, 2010
Canadian GAAP	$	30,554,892
Deferred exploration costs prior to the establishment of proven and probable reserves		(14,790,303	)
U.S. GAAP	$	15,764,589

Statement of Operations	Nine Months Ended December 31, 2010			Year Ended March 31, 2009
Net loss based on Canadian GAAP	$	(1,051,649	)	$	(373,071	)
Deferred exploration costs prior to the establishment of proven and probable reserves		(643,020	)		(944,414	)
Net loss based on U.S. GAAP	$	(1,694,669	)	$	(1,317,485	)

Note 4 - Acquisition Accounting

The acquisition of X-Cal by Paramount has been accounted for using the acquisition method of accounting in accordance with ASC 805. Further, under the acquisition method, the purchase price is allocated to assets acquired and liabilities assumed based on their estimated fair values, with any excess of the purchase price over the estimated fair value of the identifiable net assets acquired recorded as goodwill.

The cost of the acquisition and related purchase price allocation included in the accompanying unaudited pro forma condensed combined financial statements is based on a preliminary evaluation of the fair value of the assets and liabilities assumed of X-Cal and may change when the final valuation of acquired assets and working capital is determined. Given a complete change in the accounting basis of X-Cal, the cost of acquisition represents the total fair value of X-Cal at the date of acquisition. The total fair value of X-Cal was calculated by the outstanding common shares of X-Cal and the closing share price of Paramount on June 22, 2010, plus the estimated fair value of options and warrants of Paramount issued pursuant to the Agreement. The ultimate purchase price will change based on movements in Paramount’s share price until the final closing date.

The following represents the preliminary allocation of the cost of acquisition:

Shares eligible for conversion		167,548,439
Common stock exchange ratio per share		0.125
Equivalent new shares issued (par value $0.01)		20,943,555
Paramount common stock price on June 22, 2010	$	1.43
Total preliminary purchase price (common stock)		29,949,283
Estimated fair value of warrants issued (Note 5e)		699,875
Estimated fair value of options issued (Note 5f)		222,432
Total preliminary purchase price	$	30,871,590

The purchase price will be computed using the value of Paramount common stock on the closing date, therefore the actual purchase price will fluctuate with the market price of Paramount common stock until the Transaction is closed. As a result, the final purchase price could differ significantly from the current estimate, which could materially impact the pro forma financial statements.

The following table provides sensitivities to changes in purchase price due to changes in the per share price of Paramount common stock:

	Price of Paramount Common Stock		Exchange Ratio		Calculated per Share Value of X-Cal Common Stock		Total Purchase Price
As of June 22, 2010	$	1.43		0.125	$	0.17875	$	29,949,283
Decrease of 10%	$	1.29		0.125	$	0.16087	$	26,954,355
Increase of 10%	$	1.57		0.125	$	0.19662	$	32,944,212

Note 5 – Pro Forma Adjustments

(a)

To adjust mineral property exploration costs that were capitalized under Canadian GAAP, but would have been expensed under U.S. GAAP (see Note 3).
