         Company,  on the terms and subject to the  conditions  hereinafter  set
         forth;

NOW, THEREFORE,  THIS AGREEMENT WITNESSETH that in consideration of the premises
and the mutual  covenants and agreements  hereinafter set forth, IT IS AGREED as
follows:

1.       APPOINTMENT

(1)      The Company hereby  appoints  Lakehead and Lakehead hereby accepts such
appointment  to provide  Management  Services  (as  hereinafter  defined) to the
Company for an initial term of two (2) year from the date of this Agreement, and
thereafter  annually,  and  subject  to the  rights of the  parties  to  earlier
termination as provided for in Section 5 below.

(2)      During  the  term of this  Agreement,  Lakehead  shall  diligently  and
faithfully  devote the time,  effort and  ability to the  Company's  affairs and
business  necessary to perform its duties under this  Agreement.  Lakehead shall
conduct  the  operations  of  the  Company  in  an  efficient,  trustworthy  and
businesslike manner to the advantage and benefit of the Company.

2.       MANAGEMENT SERVICES

(1)      Lakehead  agrees to provide to the Company the  services of Turnbull as
the  President  of the  Company on  substantially  a full time  basis  (that is,
approximately  90% of Turnbull's  working hours based on a forty hour work week)
during  the  term of  this  Agreement  (herein  referred  to as the  "Management
Services").

(2)      It is the intent of the  parties  that  Turnbull  be a director  of the
Company at all times while this  Agreement  is in force,  and the Company  shall
take such steps as it is permitted by law such that  Turnbull will become and so
remain a director.  Turnbull  hereby consents to being a director of the Company
at all times when this Agreement is in force.

(3)      Except  as  otherwise  acknowledged  herein,  during  the  term of this
Agreement,  each of Lakehead and Turnbull  agree that it shall not,  without the
prior  written  consent of the  Company,  directly or  indirectly  engage in any
business  activity  or  enterprise  competitive  with the Company in the Russian
Federation,  Kyrgyzstan,  Kazakhstan,  Uzbekistan and Tajikistan,  and,  without
restricting  the generality of the foregoing,  Turnbull shall not accept any new
position  with  another  business  entity,  be it as a  director  or  officer or
otherwise,  without the prior  written  consent of the Board of Directors of the
Company.

(4)      The Company  acknowledges  that  Turnbull will be entitled to three (3)
weeks  paid leave per year to be taken at such time as the Board may judge to be
convenient to the Company.

3.       REMUNERATION

(1)      The Company hereby agrees to pay to Lakehead,  as remuneration  for the
provision  of the  Management  Services,  the sum of $12,500  per month  payable
retroactively  from July 1,  2007,  which sum is  subject to review on the first
anniversary of this Agreement.


<PAGE>


                                     - 3 -


(2)      The  Company  further  agrees  to  reimburse  to  Lakehead  the  actual
out-of-pocket  expenses  incurred  by  Lakehead,   its  consultants,   advisors,
sub-agents  and  employees,  in  connection  with  the  provision  of any of the
services hereunder. For all such expenses, Lakehead shall furnish to the Company
statements with full written  back-up on a monthly basis.  The Company shall not
be responsible for paying any "benefits" to Lakehead employees.  Notwithstanding
the foregoing,  the Company shall bear the cost of customary travel and accident
insurance  incurred by  Turnbull  while on Company  business  outside of Canada,
including the costs of emergency medical evacuation,  where such coverage is not
otherwise provided by the Company to Turnbull.

4.       CONFIDENTIALITY

(1)      Lakehead acknowledges that it and its consultants, advisors, sub-agents
and  employees,  have and will acquire  information  about  certain  matters and
things which are confidential or secret to the Company and which  information is
the exclusive property of the Company (the "Confidential Information"). Lakehead
undertakes  not to  disclose,  and to  ensure  that its  consultants,  advisors,
sub-agents and employees do not disclose,  the  Confidential  Information or any
information  which,  in good  faith  and  conscience,  ought  to be  treated  as
confidential,  to any third party  either  during the term of this  Agreement or
after,  except as may be  necessary in the proper  discharge  of its duties,  as
required  by law,  or with the prior  written  permission  of the  Company.  The
foregoing  obligations  shall continue  beyond the termination of this Agreement
and shall be binding upon  Lakehead's  successors and assigns.  Lakehead  agrees
that  disclosure  by it of such  information  or trade  secrets  may  result  in
irreparable  injury and  damage to the  Company,  which  will not be  adequately
compensable in money damages,  that the Company will have no adequate  remedy at
law  therefor,  and that the  Company  shall  have the right,  and may,  without
objection  from  Lakehead,  obtain  such  preliminary,  temporary  or  permanent
mandatory or restraining  injunctions,  orders or decrees as may be necessary to
protect  the  Company  against,  or on account of any breach by  Lakehead of the
provisions of this section.  Nothing herein shall be construed as preventing the
Company  from  pursuing  any other  remedies  available to it for such breach or
threatened breach, including the recovery of damages from Lakehead.

(2)      Turnbull  acknowledges  that  he  has  and  will  acquire  Confidential
Information. Turnbull undertakes not to disclose the Confidential Information or
any  information  which,  in good faith and  conscience,  ought to be treated as
confidential,  to any third party either during his employment or after,  except
as may be necessary in the proper  discharge of his duties,  as required by law,
or with the prior written permission of the Company.  The foregoing  obligations
shall  continue  beyond the  termination  of this Agreement and shall be binding
upon Turnbull's heirs, executors,  successors and assigns.  Turnbull agrees that
disclosure by him of such information or trade secrets may result in irreparable
injury and damage to the Company,  which will not be adequately  compensable  in
money  damages,  that the Company will have no adequate  remedy at law therefor,
and that the  Company  shall have the right,  and may,  without  objection  from
Turnbull,   obtain  such  preliminary,   temporary  or  permanent  mandatory  or
restraining  injunctions,  orders or decrees as may be  necessary to protect the
Company  against,  or on account of any breach by Turnbull of the  provisions of
this paragraph. Nothing herein shall be construed as preventing the Company from
pursuing  any other  remedies  available  to it for such  breach  or  threatened
breach, including the recovery of damages from Turnbull.

5. TERMINATION

(1)      Lakehead may terminate this Agreement by three months written notice to
the Company,  for any reason.  The Company may waive such notice, in whole or in
part. On such termination  Turnbull shall be deemed to have resigned from all of
his positions with the Company. Lakehead will be entitled on termination to fees
and expenses due to the date of termination.

(2)      The Company may terminate this  Agreement "for cause" (theft,  fraud or
material  dishonesty  or  misconduct  by Lakehead,  its  consultants,  advisors,
sub-agents  and  employees,  involving  the  property or affairs of the Company)
without  any  notice  or  compensation  in lieu  thereof.  On such  termination,
Turnbull  shall be deemed to have resigned  from all of his  positions  with the
Company.

(3)      This  Agreement  will  terminate  in the event of the death of Turnbull
prior to the end of the term of this  Agreement.  The Company may terminate this
Agreement  in the event  Turnbull is not  available or able to work by reason of
illness  or mental or  physical  disability  or  incapacity  which  lasts for an
uninterrupted  period  of not less  than  six  months,  and on such  termination
Turnbull  shall be deemed to have resigned  from all of his  positions  with the
Company.

(4)      The Company  may  terminate  this  Agreement  in its sole and  absolute
discretion  for  any  reason  and  without  cause,  and in  the  event  of  such
termination or in the event of the Constructive Dismissal of Turnbull,  Turnbull
shall be deemed to have resigned from all of his positions  with the Company and
the Company  shall pay to Lakehead a lump sum payment  equal to twelve times the
monthly fee payable to Lakehead at the time of termination  for the provision of
Management Services.

(5)      Save and except as otherwise provided in this Agreement,  "Constructive
Dismissal" for the purposes of this Agreement shall mean:

         (a)      Turnbull ceasing to be a director  (otherwise than pursuant to
                  his voluntary resignation), or any other material reduction in
                  Turnbull's  title,   reporting   responsibilities,   function,
                  responsibility or authority with the Company; and

         (b)      any  material   reduction  in  Lakehead's  total  compensation
                  package, as provided herein.

(6)      Without  limiting  any  other  rights  Lakehead  may  have  under  this
Agreement,  in the event of a Change of Control, as defined below,  Lakehead may
elect,  during the six month period immediately  following the date of Change of
Control,  to terminate this Agreement,  in which case such termination  shall be
deemed to be a Constructive Dismissal of Turnbull by the Company.

(7)      In this Agreement, "Change of Control" shall mean the occurrence, after
the date hereof,  of the  acquisition  of common  shares of the Company or other
securities of the Company  having the right to vote generally in the election of
directors  of the  Company  (the  common  shares and such other  securities  are
hereinafter  referred to as the "Voting Shares") or of securities  ("Convertible
Securities")  convertible  into,  exchangeable  for or representing the right to
acquire  Voting  Shares of the  Company as a result of which a person,  group of
persons or  persons  acting  jointly or in  concert,  or persons  associated  or
affiliated within the meaning of the Securities Act



<PAGE>


                                     - 5 -


(British Columbia) with any such person, group of persons or any of such persons
acting jointly or in concert (collectively,  the "Acquirers"),  beneficially own
Voting Shares of the Company and/or Convertible  Securities such that,  assuming
the  conversion,  exchange or exercise of  Convertible  Securities  beneficially
owned by the Acquirers,  the Acquirers would  beneficially  own Voting Shares of
the Company that would entitle the holders  thereof to cast more than 25% of the
votes  attaching to all Voting  Shares in the capital of the Company that may be
cast to elect directors of the Company provided,  however,  that transfers among
now affiliated or associated  corporations,  persons or legal entities shall not
result in a "Change of Control".

6.       PERSONAL SERVICES

(1)      The Management  Services to be provided by Lakehead pursuant hereto are
personal in  character,  and neither this  Agreement  nor any rights or benefits
arising  thereunder  are  assignable  by Lakehead  without the previous  written
consent of the Company.

7.       NOTICES

(1)      Any notice,  direction or other instrument  required or permitted to be

Canada or by sending same by telefax or other similar form of communication,  in

day it was actually received.

(3)      Any party may, at any time, give notice in writing to the others of any

therein  specified  will be  deemed  to be the  address  of such  party  for the
purposes of giving notice hereunder.

8.       GENERAL

(1)      The provisions of this  Agreement  shall enure to the benefit of and be
binding upon the legal personal  representatives  of Lakehead and the successors

communications.  In particular,  the agreement  between the 0724000 B.C. Ltd., a

or remedy.

(7)      Each of the  parties  agrees  that it shall from time to time take such
actions and execute such additional  instruments as may be reasonably  necessary

illegal or invalid for any  reason,  such  illegality  of  invalidity  shall not
affect  the  remaining  provisions  which  shall  be fully  severable,  and this
Agreement  shall be  construed  and enforced  without  regard to such illegal or
invalid provision. The parties agree to execute such additional documents as may
be  necessary  to give  effect  to any  clause,  term or part  hereof  which  is
determined to be illegal, unenforceable, in conflict with any law or contrary to
public policy.

legal advice or waives such advice.  Turnbull  acknowledges that he has read and
