(C) It is the intent of the Payee and the Payor in the execution of this Note
that the loan evidenced hereby comply with the restrictions of applicable state
usury laws.  If, for any reason, it should be determined that any usury law is
applicable (which the parties do not believe to be the case), the Payor and the

pursuant to this Note) pursuant to this Note or in any other instrument
evidencing or securing the indebtedness evidenced herein shall be limited to the
maximum permitted by such law, (ii) none of the terms and provisions contained

detention of money requiring payment of interest at a rate in excess of the
maximum interest rate permitted to be charged by any state laws which are
applicable, (iii) the obligation of the Payor shall be reduced to the maximum
rate permitted to be charged by any state laws which are applicable, and (iv)
the Payee shall not collect monies which would otherwise increase the effective
interest rate on this Note to a rate in excess of the maximum rate permitted to
be charged by any such applicable state law.  Any sums collected which are in
excess of such maximum rate shall be credited to the payment of any other sums
due hereunder.  If no sums are due hereunder, then such excess shall be returned
to the Payor.

provided, however, if an Event of Default pursuant to Article “10” of this Note
occurs, this Note shall be subject to an interest rate of twenty (20%) percent

--------------------------------------------------------------------------------

 
 
(i.) If the Payee does not provide written notice of its intention to convert
some or all of the unpaid principal and any accrued and unpaid interest due,
Payor shall pay the amount due on the Maturity Date.
 
(ii.) If all or part of this Note is converted pursuant to Paragraph “A” of this
Article “5” of this Note, the shares shall be delivered to the Payee within
three (3) business days after the date upon which the Payor receives a
Conversion Notice (such third (3rd) business day the “Conversion Share Due
Date”), in the form attached hereto as Exhibit “A”; provided, however,  that a
Conversion Notice delivered after 1:00 o’clock P.M. on any business day shall be
deemed to be delivered on the next following business day.
 
(iii.) If all or part of this Note is converted pursuant to Paragraph “A” of
this Article “5” of this Note, all shares delivered to the Payee shall be
free-trading if the shares are issued after six (6) months after the date of
this Note.  If any shares delivered to the Payee are not free-trading, on May 3,
2012, at its own cost, the Company shall cause its counsel to issue an opinion
letter to the Company’s transfer agent, or its successor (the “Transfer Agent”),
that the said shares may be sold or transferred without restriction or
limitation in reliance on Rule 144 promulgated under the Securities Act of 1933,
as amended, and direct the Transfer Agent to replace such shares with a
certificate that does not contain a restrictive legend. After the receipt by the
Transfer Agent of the certificate representing such shares from Tangiers (or its
broker) requesting the issuance of an unrestricted certificate, the Company
shall cooperate fully with the Transfer Agent. If the newly issued unrestricted
stock is not delivered to Tangiers or its broker within four (4) business days
after the receipt of the restricted shares, the Company shall pay an additional
amount of one thousand dollars ($1,000) per calendar day for each day that
delivery of the unrestricted stock certificate is delayed; provided, however,
that receipt of the restricted certificate after 1:00 p.m. local time shall be
deemed to be receipt on the next following business day. The Company
acknowledges that it would be extremely difficult or impracticable to determine
Tangiers’ actual damages and costs resulting from the delay in making delivery
of the unrestricted stock certificate and the inclusion herein of any such
additional amounts are the agreed upon liquidated damages representing a
reasonable estimate of those damages and costs and do not constitute a penalty.
 
(B) The Payor shall pay any and all stock transfer fees. No fractions of shares
or scrip representing fractions of shares will be issued upon conversion, but
the number of shares issued shall be rounded to the nearest whole share, based
upon the total number of shares of Common Stock to be issued to the Payee.  The
date upon which a Conversion Notice is received by the Payor shall be deemed to
be the date upon which the Payee has delivered the conversion notice duly
executed, to the Payor; provided, however, that a Conversion Notice delivered
after 1:00 o’clock P.M. on any business day shall be deemed to be delivered on
the next following business day.  Upon receipt of the Shares for the full
conversion and/or payment of this Note, the Payee shall deliver this Note to the
Payor marked “cancelled.”
 
(C) If the Payor fails to deliver shares timely pursuant to this Article “5” of
this Note, the Payor shall pay to the Payee an additional amount of shares equal
in number to one (1%) percent of the number of shares of Common Stock required
to be issued per calendar day for each calendar day that the shares are delayed
after the Conversion Share Due Date.  The Payor acknowledges that it would be
extremely difficult or impracticable to determine the Payee’s actual damages and
costs resulting from the delay in delivering the Shares on or prior to the
Conversion Share Due Date and the inclusion herein of any such additional
amounts are the agreed upon liquidated damages representing a reasonable
estimate of those damages and costs and do not constitute a penalty.

--------------------------------------------------------------------------------

 
 
(D) If, upon Tangiers’ request to convert all or part of this Note pursuant to
this Article “5” of this Note, the shares are not available by reason of the
Payor not having enough authorized and unissued shares to issue the shares to
Tangiers, the Payor shall take all necessary action to increase the number of
authorized shares of the Company’s Common Stock to satisfy Tangiers’ request to
convert all or part of this Note.
 
(E) In order to preserve the conversion rights of the Payee, the conversion rate
is subject to adjustment if certain events occur, including, but not limited to,
any of the events that are set forth below:
 
(i.) The issuance of any previously authorized or newly authorized shares
(common or any other securities convertible into common) of the Payor for less
than the conversion price per share at the time of conversion pursuant to this
Article “5” of this Note;
 
(ii.) A recapitalization of the outstanding shares of the Payor which has the
effect of changing the percentage of shares which this Note may be converted
into in relation to the total number of outstanding shares;
 
(iii.) The payment of any stock dividends;
 
(iv.) The distribution to any holders of shares of the Payor’s securities,
evidences of indebtedness of the Payor or assets (excluding cash dividends paid
from retained earnings);
 
(v.) The issuance after the date hereof of any stock options, warrants or other
rights to acquire shares in the Payor at a price less than the current market
value of such shares; and
 
(vi.) Any capital reorganization by the Payor, any reclassification or
recapitalization of the Payor’s capital stock, or any transfer of all or
substantially all the assets of the Payor to or consolidation or merger of the
Payor with or into any other Person.
 
(F) Upon the occurrence of any of the above events (any of such events is
hereinafter referred to as a “Dilution Event”), then, in such event, the Payor
will immediately take whatever measures are necessary to insure that the
percentage interest in the Payor which the Note may be converted into would not
be increased or reduced.  Any adjustment which is required by this Paragraph “F”
of this Article “5” of this Note shall be deemed effective retroactive to the
date of the Dilution Event.  The provisions of this Paragraph “F” of this
Article “5” of this Note shall be applicable to any Dilution Event which occurs
at any time after the date of this Note.  If any of the Dilution Events occur,
the Payor will mail or cause to be mailed a notice pursuant to Paragraph “C” of
Article “20,” to the Payee of this Note specifying the Dilution Event(s) which
has occurred.
 
(G) As long as this Note is outstanding and no Event of Default has occurred,
neither Tangiers nor its affiliates shall at any time engage in any short sale
of, or sell put options or similar instruments with respect to, the Company’s
stock.
 
6. Opinions.
 
(A) Inclusive within the $2,500 funds paid by Payor at the closing of this
transaction is the cost for preparation of a legal opinion. The Payee’s counsel
shall provide the appropriate opinion letters to the Transfer Agent in
compliance with the provisions of Rule 144 promulgated by the Securities and
Exchange Commission pursuant to §4(1) of the Securities Act of 1933, as amended,
with respect to the transfer or sale of the shares, if such transfer or sale is
permissible under Rule 144.
 
(B) Upon execution of this Note, the Payor shall deliver to Payee the
Irrevocable Transfer Agent Instructions, in the form attached hereto as Exhibit
“B”.

 (A)           If the Payor shall at any time when Payee has not received a
stock certificate evidencing the shares without a restrictive legend, seek to
register or qualify any of its capital stock or the securities holdings of any
of its controlling shareholders, on each such occasion it shall include all of
the Payee’s shares pursuant to Article “5” of this Note in such registration or
qualification at the Payor’s expense.  The Payor shall keep the registration
