COMPANY will be entitled to additional compensation upon the consummation of a
Potential Transaction, as outlined below.
 
 Equity:In
the event the Potential Transaction involves a placement of equity or
equity-linked securities to investors (the “VASTANI Equity Investors”)
introduced and solely indentified by VASTANI COMPANY (the “Securities”), the
Company agrees to pay VASTANI COMPANY a placement fee (the “Equity Placement
Fee”) equal to seven percent (7%) of the Securities placed with the VASTANI
Equity Investors, payable in full, in cash. VASTANI COMPANY may also accept
freely tradable shares of Company’s common stock  as payment with a
minimum discount of 25% of the price at which the Securities were placed. The
Equity Placement Fee is due and payable upon the closing of the sale of any of
the Securities, including the receipt of the investment. The minimum fee payable
in connection with any Potential Transaction shall be $10,000. If the placement
of the Securities takes the form of an underwritten public equity offering and
in the event Paramount Gold and Silver waives its right of first refusal, then
VASTANI COMPANY shall have the right of first refusal to participate therein as
a managing underwriter with a minimum of 50% economic participation, provided
that VASTANI COMPANY provides the Company with terms and conditions consistent
with industry norms.  In the event that VASTANI COMPANY acts the
managing underwriter, its sole compensation in connection with that placement
will be those agreed upon in an Underwriting Agreement and the Equity Placement
Fee will not apply.
 
 Debt: In
the event the Potential Transaction involves a placement of debt to investors
(the “VASTANI Debt Investors”) introduced and solely indentified by VASTANI
COMPANY, the Company agrees to pay VASTANI COMPANY a placement fee (the “Debt
Placement Fee”) equal to four percent (4%) of the gross proceeds received under
the debt facility from the VASTANI Debt Investors, payable in full, in cash,
upon the closing of the debt facility provided that the minimum fee payable in
connection with any such Potential Transaction shall be $25,000.

purchase option, a merger or consolidation, a leveraged buy-out or
recapitalization, the formation of a joint venture, a minority investment or
partnership, or any similar transaction; or b) the acquisition of any party

consolidation, reorganization or other business combination, or by a purchase of

transaction fee (the “Transaction Fee”) equal to four percent (4%) of the

Company (or Target) and/or its shareholders, option holders and warrant holders
from the Acquirer (or the Company) in such Transaction (net of any consideration
received by the Company (or Target) upon the exercise of any options or warrants
issued prior to the day hereof) and (ii) the amount of indebtedness of the
Company (or Target) or any of its affiliates paid or assumed directly or

Transaction resulting in a change of control, but acquired less than all of such
capital stock, the value of the capital stock remaining outstanding immediately

Company.

   INDEMNIFICATION
AGREEMENT
 
 
 
 In connection with the engagement of
VASTANI COMPANY by MEXORO MINERALS LTD. (the “Company") pursuant to a letter
agreement, dated July 1st, 2008,
between the Company and VASTANI COMPANY (the "Engagement Agreement"), VASTANI
COMPANY and the Company hereby agree as set forth herein. For purposes of the
remainder of this Indemnification Agreement, unless the context otherwise
requires, "VASTANI COMPANY " shall include VASTANI COMPANY , any affiliated
entity, and each of their respective officers, directors, employees, partners
and controlling persons within the meaning of the federal U.S. securities laws
and the successors, assigns, heirs and personal representatives of the foregoing
persons (collectively, the “Indemnified Persons”).
 
 The Company will indemnify VASTANI
COMPANY against any losses, claims, damages, liabilities, costs and expenses
(including, without limitation, any legal or other expenses incurred in
connection with investigating, preparing to defend or defending against any
action, claim, suit or proceeding, whether commenced or threatened and whether
or not VASTANI COMPANY is a party thereto, or in appearing or preparing for
appearance as a witness), based upon, relating to or arising out of or in
connection with advice or services rendered or to be rendered pursuant to the
Engagement Agreement, the transaction contemplated thereby or VASTANI COMPANY’s
actions or inactions in connection with any such advice, services or transaction
(including, but not limited to, any liability arising out of (i) any
misstatement or alleged misstatement of a material fact in any Confidential
Information (including any "Confidential Information" (as defined in the
Engagement Agreement)) and (ii) any omission or alleged omission
from  any Confidential Information (including any "Confidential
Information" (as defined in the Engagement Agreement")), including, without
limitation of a material fact necessary to make the statements therein, in light
of the circumstances under which they were made, not misleading), except to the
extent that any such loss, claim, damage, liability, cost or expense results
solely from the gross negligence or bad faith of VASTANI COMPANY in performing
the services which are the subject of the Engagement Agreement.  If
for any reason the foregoing indemnification is unavailable to VASTANI COMPANY
or insufficient to hold it harmless, then the Company shall contribute to the
amount paid or payable by VASTANI COMPANY as a result of such loss, claim,
damage or liability in such proportion as is appropriate to reflect the relative
benefits received by the Company and its stockholders on the one hand and
VASTANI COMPANY on the other hand, or, if such allocation is not permitted
by
   
  applicable
law, not only such relative benefits but also the relative fault of the Company
and VASTANI COMPANY , as well as any relevant equitable considerations;
provided, however, that, to the extent permitted by applicable law, VASTANI
COMPANY shall not be responsible for amounts which in the aggregate are in
excess of the amount of all fees actually received from the Company in
connection with the engagement. Relative benefits to VASTANI COMPANY , on the
one hand, and the Company and its stockholders, on the other hand, with respect
to the engagement shall be deemed to be in the same proportion as (i) the total
value paid or proposed to be paid or received or proposed to be received by the
Company or its stockholders, as the case may be, pursuant to the Potential
Transaction, whether or not consummated, contemplated by the engagement bears to
(ii) all fees paid to VASTANI COMPANY by the Company in connection with the
engagement. VASTANI COMPANY shall not have any liability to the Company in
connection with the engagement, except to the extent of its gross negligence or
willful misconduct. VASTANI COMPANY shall notify the Company in a timely manner
of any action, claim, suit or proceeding, whether commenced or threatened, and
VASTANI COMPANY shall cooperate with the Company in its defense of such actions,
claims, suits or proceedings.
 
 The Company also agrees to promptly
upon demand reimburse VASTANI COMPANY for its legal and other expenses
reasonably incurred by it in connection with investigating, preparing to defend
or defending any lawsuits, investigations, claims or other proceedings in
connection with any matter referred in to or otherwise contemplated by the
Engagement Agreement; provided, however, that in the event a final judicial
determination is made to the effect that VASTANI COMPANY is not entitled to
indemnification hereunder, VASTANI COMPANY will remit to the Company any amounts
that have been so reimbursed.
 
 The Company shall not be liable for any
settlement of any action, claim, suit or proceeding (or for any related losses,
damages, liabilities, costs or expenses) if such settlement is effectuated
without its written consent, which shall not be unreasonably
withheld.  The Company further agrees that it will not settle or
compromise or consent to the entry of any judgment in any pending or threatened
action, claim, suit or proceeding in respect of which indemnification or
contribution may be sought hereunder (whether or not VASTANI COMPANY is a party
therein) unless the Company has obtained an unconditional release of VASTANI
COMPANY , from all liability arising there from.  The reimbursement,
indemnity and contribution obligations of The Company set forth in this
Indemnification Agreement shall be in addition to any liability which The
Company may otherwise have to VASTANI COMPANY .
 
 Both parties represent and warrant that
this Indemnification Agreement has been duly authorized, executed and delivered
by each party and constitutes the legal, valid and binding obligation of both
parties.
 
 Any Indemnified Persons that are
not signatories to this Indemnification Agreement shall be deemed to be third
party beneficiaries of this Agreement.
 
 This
Indemnification Agreement shall be governed by and construed in accordance with
the laws of New York and the place of jurisdiction shall be New York County, New
York, without regard to its principles of conflicts of laws. VASTANI COMPANY
hereby agrees, and the Company hereby agrees on its own behalf and, to the
extent permitted by applicable law, on behalf of its security holders, to waive
any right to trial by jury with respect to any claim, counterclaim or action
arising out of the engagement, VASTANI COMPANY’s performance thereof or the
Agreement.  The parties hereto consent to the venue of and submit to
the jurisdiction of the Federal and State courts located in New York County, New
York.
   
  
 This Indemnification Agreement shall
survive any termination of the Engagement Letter.
