ARDENT MINES LIMITED

EMPLOYMENT AGREEMENT

EMPLOYMENT AGREEMENT, dated as of the date set forth on the signature page
hereto (the “Agreement”), by and between Ardent Mines Limited, a Nevada
corporation (the “Company”), and Leonardo Riera (the “Executive”).

WHEREAS, the Company desires to engage the Executive to serve the Company as the
President and the Executive desires to serve as the President and Chief
Executive Officer (“CEO”) of the Company;

NOW THEREFORE, in consideration of the premises and the mutual agreements made
herein, the Company and the Executive agree as follows:

1.           Employment; Duties.  The Company shall engage the Executive to
serve as President and CEO of the Company.  The Executive shall serve the
Company in such capacity for the “Employment Period” as defined in Section
2.  The Executive agrees that during the term of his employment hereunder, he
shall devote approximately seventy-five to one hundred percent (75% - 100%) of
his professional working time, attention, knowledge and experience and give his
best effort, skill and abilities to promote the business and interests of the
Company as directed by the Board of Directors of the Company or a committee of
the Board of Directors to which the Board of Directors has duly delegated
authority thereof (collectively, the “Board”).  The Company acknowledges and
agrees that the services rendered to the Company shall not be exclusive to the
Company and the Executive may pursue other business activities so long as such
other business activities are not in conflict with the Company.  In the event
that the Executive is retained as an officer, director, employee or consultant
of another business, he shall notify the Board of such engagement within five
(5) business days.  The Executive agrees to faithfully and diligently perform
such reasonable duties commensurate with the position of President as may from
time to time be assigned to the Executive by the Board.  For purposes of
clarity, except with respect to subsidiaries of the Company, to the extent the
Executive renders services to any other organizations, all such services must be
rendered in a separate capacity and shall not be deemed to constitute services
of the Executive as an agent of any such other organization to the Company or by
or on behalf of the Company to such other organizations unless expressly
delegated in writing to such effect.

2.           Employment Period.  This Agreement shall have an initial term of
two years to be effective commencing as of the date hereof and ending on the
second anniversary hereof (the “Initial Employment Period”), unless sooner
terminated in accordance with the provisions of Section 7 or Section 8.  This
Agreement shall automatically renew and continue to remain in effect after the
Initial Employment Period for successive one year periods (each, a “Renewal
Employment Period”), until terminated as provided herein, unless either party
provides the other party with written notice of non-renewal not later than 30
days prior to the expiration of the Initial Period or the anniversary of such
date in any subsequent Renewal Employment Period.  The Initial Employment Period
and each Renewal Employment Period of this Agreement is referred to herein as
the “Employment Period.”

amounts shall be due and payable.

(b)           Stock Grant.  The Executive shall be granted fifty thousand
(50,000) restricted shares of the Company’s common stock (the “Shares”).  Until
the second anniversary of the date hereof, the Shares may not be sold,

or breach of, or constitute (with or without notice or lapse of time or both) a
default under any contract, agreement or understanding, whether oral or written,
to which the Executive is a party or of which the Executive is or should be
aware and that there are no restrictions, covenants, agreements or limitations
on his right or ability to enter into and perform the terms of this Agreement,
and agrees to indemnify and save the Company and its affiliates harmless from
any liability, cost or expense, including attorney’s fees, based upon or arising
out of any such restrictions, covenants, agreements, or limitations that may be
found to exist.  For purposes of this Agreement, “affiliate” shall include any
subsidiary in the case of the Company, and any person or entity directly or
indirectly controlled by or controlling the Company.

10.           Non-competition.   Except as authorized by the Board of Directors,
during the Executive’s employment by the Company and for a period of one year
thereafter, Executive will not (except as an officer, director, stockholder,
employee, agent or consultant of the Company or any subsidiary or affiliate
thereof) either directly or indirectly, whether or not for consideration, (i) in
any way, directly or indirectly, solicit, divert, or take away the business of
any person who is or was a customer of the Company, or in any manner influence
such person to cease doing business in part or in whole with Company; (ii)
engage in a Competing Business; (iii) except for investments or ownership in

more than 5% of the ownership or control of such entities, own, operate,

subsidiaries or affiliates.  In the event that the Executive’s employment by the

limitations of this Section 10 shall cease to apply as of the final payment made
in respect of the termination of the Executive’s employment with the Company as

11.           Non-Solicitation.  During the Executive’s employment by the
Company and for a period of one year thereafter (the “Restricted Period”), the
Executive, directly or indirectly, whether for his account or for the account of
any other individual or entity, shall not solicit or canvas the trade, business
or patronage of, or sell to, any individuals or entities that were either
customers of the Company during the time the Executive was employed by the
Company, or prospective customers with respect to whom a sales effort,
presentation or proposal was made by the Company or its affiliates, during the
one year period prior to the termination of the Executive’s employment.  The
Executive further agrees that during the Restricted Period, he shall not,
directly or indirectly, (i) solicit, induce, enter into any agreement with, or
attempt to influence any individual who was an employee or consultant of the
Company at any time during the time the Executive was employed by the Company,
to terminate his or her employment relationship with the Company or to become
employed by the Executive or any individual or entity by which the Executive is
employed or (ii) interfere in any other way with the employment, or other
relationship, of any employee or consultant of the Company or its affiliates.

12.           Enforcement.  The Executive agrees that any breach of the
provisions of this Agreement would cause substantial and irreparable harm, not
readily ascertainable or compensable in terms of money, to the Company for which
remedies at law would be inadequate and that, in addition to any other remedy to
which the Company may be entitled at law or in equity, the Company shall be
entitled to temporary, preliminary and other injunctive relief in the event the
Executive violates or threatens to violate the provisions of this Agreement, as
well as damages, including, without limitation consequential damages, and an
equitable accounting of all earnings, profits and benefits arising from such
violation, in each case without the need to post any security or bond.  Nothing
herein contained shall be construed as prohibiting the Company from pursuing, in
addition, any other remedies available to the Company for such breach or
threatened breach.  A waiver by the Company of any breach of any provision
hereof shall not operate or be construed as a waiver of a breach of any other
provision of this Agreement or of any subsequent breach by the Executive.

13.           Determinations by the Company.  All determinations and
calculations with respect to this Agreement shall be made by the Board or any
committee thereof to which the Board has delegated such authority, in good faith
in accordance with applicable law, the certificate of incorporation and by-laws
of the Company, in its sole discretion, and shall be final, conclusive and
binding on all persons, including the Executive and the personal representative
of his estate.

14.           Successors and Assigns.  This Agreement shall inure to the benefit
of and shall be binding upon (i) the Company, its successors and assigns, and
any company with which the Company may merge or consolidate or to which the
Company may sell substantially all of its assets, and (ii) Executive and his
executors, administrators, heirs and legal representatives.  Since the
Executive’s services are personal and unique in nature, the Executive may not
transfer, sell or otherwise assign his rights, obligations or benefits under
this Agreement.
