Forward looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by management are inherently subject to significant business, economic and competitive uncertainties and contingencies. We caution that such forward-looking statements involve known and unknown risks, uncertainties and other risk factors that may cause the actual financial results, performance, or achievements of Gold Reserve to be materially different from our estimated future results, performance, or achievements expressed or implied by those forward looking statements. Numerous factors could cause actual results to differ materially from those in the forward-looking statements, including without limitation, concentration of operations and assets in foreign countries, corruption, requests for improper payments, uncertain legal enforcement, regulatory, political and economic risks associated with Venezuelan operations, our ability to obtain additional funding for the development of the Brisas project, in the event any key findings or assumptions previously determined by our experts in the final feasibility study (including any updates thereto) significantly differ or change as a result of actual results in our expected construction and production at the Brisas project, risk that actual mineral reserves may vary considerably from estimates presently made, impact of currency, metal prices and metal production volatility, changes in proposed development plans (including technology used), our dependence upon the abilities and continued participation of certain key employees, and risks normally incident to the operation and development of mining properties. These are discussed in greater detail in Gold Reserve's filings with the U.S. Securities and Exchange Commission at www.sec.gov and the Annual Information Form and other reports filed with Canadian provincial securities commissions at www.sedar.com. Gold Reserve expressly disclaims any intention or obligation to update or revise any forward looking statement whether as a result of new information, events or otherwise.

Those securities classified as available-for-sale would be recorded at market value and the unrealized gain or loss would be recorded as part of comprehensive income. B For U.S. GAAP purposes, the Company accounts for stock-based employee compensation arrangements using the intrinsic value method prescribed in Accounting Principles Board (APB) Opinion No.25, iAccounting for Stock Issued to Employeesi. Under U.S. GAAP, when the exercise price of certain stock options is amended (the iRepricing i), these options are accounted for as variable compensation from the date of the effective Repricing. Under this method, following the Repricing date, compensation expense is recognized when the quoted market value of the Companyis common shares exceeds the amended exercise price. Should the quoted market value subsequently decrease, a recovery of a portion, or all of the previously recognized compensation expense will be recognized. For U.S. GAAP purposes, the Company will adopt SFAS 123R, iAccounting for Stock Based Compensationi effective January 1, 2006. SFAS 123R requires the use of the fair value method of accounting for stock based compensation. This standard is substantially consistent with the revised provisions of CICA 3870, which was adopted by the Company for Canadian GAAP effective January 1, 2004. For U.S.GAAP, the Company has not yet determined which acceptable method of adoption it will apply. C Under Canadian GAAP, the Company capitalizes mineral property exploration and development costs after proven and probable reserves have been established. The Company also capitalizes costs on properties where it has found non-reserve material that does not meet all the criteria required for classification as proven or probable reserves. Under U.S. GAAP, exploration and development expenditures incurred on properties where mineralization has not been classified as a proven and probable reserve under SEC rules, are expensed as incurred. Accordingly, certain expenditures are capitalized for Canadian GAAP purposes but expensed under U.S. GAAP. Pro-forma stock based compensation For U.S. GAAP purposes, the Company accounts for stock-based employee compensation arrangements using the intrinsic value method. Had the fair value method of accounting been used under U.S. GAAP, the net loss and net loss per share would have been as follows: 2005 2004 2003 ----------------------------------------------------------------------------- Net loss under U.S. GAAP $ (5,878,244) $ (10,359,891) $ (11,412,062) Variable plan accounting adjustment included in net loss (2,285,698) (791,643) 7,704,726 Stock based compensation under the fair value method (863,340) (599,423) (406,108) ----------------------------------------------------------------------------- Pro-forma net loss under U.S. GAAP $ (9,027,282) $ (11,750,957) $ (4,113,444) ============================================================================= Pro-forma basic and diluted net loss per share under U.S. GAAP $ (.26) $ (.40) $ (.17) ============================================================================= Development Stage Enterprise In August of 1992, the Company acquired the Brisas Project. Beginning in 1993 the Company decided to focus its efforts on the Development of Brisas thereby meeting the definition of a development stage enterprise under Statement of Financial Accounting Standards No. 7 (FAS 7), Accounting and Reporting by development Stage Enterprises.
