DOCUMENT A-04192011

ARTICLE 1 PAYMENT-RELATED PROVISIONS

1.1 Interest Rate. Subject to the Holder's right to convert, interest payable on this Note will accrue interest at the Interest Rate and shall be applied to the Principal Sum.

ARTICLE 2 CONVERSION RIGHTS

The Holder will have the right to convert the Principal Sum and accrued interest under this Note into Shares of the Borrower's Common Stock as set forth below.

2.1 Conversion Rights and Cashless Exercise. Subject to the terms set forth in Section 2.7, the Holder will have the right at its election from and after the Effective Date, and then at any time, to convert all or part of the outstanding and unpaid Principal Sum and accrued interest into shares of fully paid and nonassessable shares of common stock of Silver Dragon Resources Inc.(as such stock exists on the date of issuance of this Note, or any shares of capital stock of Silver Dragon Resources Inc. into which such stock is hereafter changed or reclassified, the "Common Stock") as per the Conversion Formula set forth in Section 2.2. Any such conversion shall be cashless, and shall not require further payment from Holder. Unless otherwise agreed in writing by both the Borrower and the Holder, at no time will the Holder convert any amount of the Note into common stock that would result in the Holder owning more than 4.99% of the common stock outstanding of Silver Dragon Resources Inc. Shares from any such conversion will be delivered to Holder by 2:30pm EST within 2 (two) business days of conversion notice delivery (see 3.1) by “DWAC/FAST” electronic transfer (see “Share Delivery” attachment).

2.2. Conversion Formula. The number of shares issued through conversion is the conversion amount divided by the conversion price.

2.3. This section 2.3 intentionally left blank.

2.4. This section 2.4 intentionally left blank.

2.5 Reservation of Shares. As of the issuance date of this Note and for the remaining period during which the conversion right exists, the Borrower will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of Common Stock upon the full conversion of this Note. The Borrower represents that upon issuance, such shares will be duly and validly issued, fully paid and non-assessable. The Borrower agrees that its issuance of this Note constitutes full authority to its officers, agents and transfer agents who are charged with the duty of executing and issuing stock certificates to execute and issue the necessary certificates for shares of Common Stock upon the conversion of this Note.

2.6. Delivery of Conversion Shares. Shares from any such conversion will be delivered to Holder by 2:30pm EST within 2 (two) business days of conversion notice delivery (see 3.1) by “DWAC/FAST” electronic transfer (see “Share Delivery” attachment). If those shares are not delivered in accordance with this timeframe stated in this Section 2.6, at any time for any reason prior to offering those shares for sale in a private transaction or in the public market through its broker, Holder may rescind that particular conversion to have the conversion amount returned to the note balance with the conversion shares returned to the Borrower. The Company will make its best efforts to deliver shares to Holder same day / next day.

2.6.1. Conversion Delay Penalties. Holder may assess penalties or liquidated damages (both referred to herein as “penalties”) as follows.

2.6.1. A. For each conversion, Borrower agrees to deliver share issuance instructions to its transfer agent same day or next day. In the event that the share issuance instructions are not delivered to the Borrower’s transfer agent by the next day, a penalty of $2,000 per day will be assessed for each day until share issuance instructions are delivered to the transfer agent ($2,000 per day inclusive of the day of the conversion); and such penalty will be added to the principal balance of the Note (under Holder and Borrower’s expectation that any penalty amounts will tack back to the original date of the note).

2.6.1. B. For each conversion, in the event that shares are not delivered by the third business day (inclusive of the day of the conversion), a penalty of $2,000 per day will be assessed for each day after the third business day (inclusive of the day of the conversion) until share delivery is made; and such penalty will be added to the principal balance of the Note (under Holder and Borrower’s expectation that any penalty amounts will tack back to the original date of the note). Borrower will not be subjected to any penalties once its transfer agent processes the shares to the DWAC system.

2.7. This section 2.7 intentionally left blank.

3.11. No Shorting. Holder agrees that so long as any Notes from Borrower to Holder remain outstanding, Holder will not enter into or effect any “short sales” of the common stock or hedging transaction which establishes a net short position with respect to the common stock of Silver Dragon Resources Inc. Borrower acknowledges and agrees that upon submission of conversion notice as set forth in Section 3.1 (up to the amount of cash paid in under the Notes), Holder immediately owns the common shares described in the conversion notice and any sale of those shares issuable under such conversion notice would not be considered short sales.
