          Re:           Bonanza Oil & Gas, Inc. (the “Company”)

Gentlemen:

          The Company hereby acknowledges that Eric Dale (“Lender”) loaned the
Company $200,000 on August 28, 2008 as evidenced by the Note attached hereto as
Exhibit A. As of the date hereof the principal and interest under the Note that
remains unpaid is $169,060.

          The Company and the Lender hereby agree that the Note shall be amended
and restated to incorporate the following provision:

> > > The Payee shall have the right on a weekly basis to convert $5,000 of the
> > > outstanding and unpaid principal amount of this Note and interest at the
> > > Fixed Conversion Price (a “Conversion”). In no event shall the Payee be
> > > entitled to convert any portion of this Note in excess of 4.9% of the
> > > outstanding shares of common stock of the Company. For purposes of the
> > > proviso to the immediately preceding sentence, beneficial ownership shall
> > > be determined in accordance with Section 13(d) of the Securities Exchange
> > > Act of 1934, as amended, and Regulations 13D-G thereunder. The “Fixed
> > > Conversion Price” shall mean $0.0025.

          The parties further acknowledge that the Lender is not an affiliate of
the Company and the Lender represents that it is not an affiliate of the
Company. As a result, the shares of common stock issued upon conversion of the
Note (the “Conversion Shares”) will be eligible to resold under Rule 144 as the
Conversion Shares holding period will tack to the initial date of issuance of
the Note. Accordingly, the Company, upon conversion of the Note and receipt of
the standard representation letters from the Lender, will direct the transfer
agent to issue the Conversion Shares without the standard “33 Act” restrictive
legend. The Company shall reserve a sufficient number of shares of common stock
for the purpose of enabling the Company to issue the Conversion Shares. This
letter agreement may be executed in one or more counterparts. We hereby request
that you execute this letter agreement below acknowledging and agreeing to the
terms set forth herein.

Sincerely,

Bonanza Oil & Gas, Inc.
