      TERMINATION
OF EMPLOYMENT

       

      9.1 Termination Without
Notice

       

      This
Agreement and the Executive’s employment with Partnership may be terminated,
without Partnership being obligated to provide the Executive with advance notice
of termination or pay in lieu of such notice, whether under contract, statute,
common law or otherwise, in the following circumstances:

       

      
        	
              	
                (a)

              	
                Voluntary
      Resignation

              

      

       

      In the
event the Executive voluntarily resigns, except where the Executive resigns for
Good Reason as provided for in this Agreement, the Executive will give a minimum
of sixty (60) days’ advance written notice to the Partnership and Gran Tierra.
The Executive will not be entitled to receive any further compensation or
benefits whatsoever other than those which have accrued up to the Executive’s
last day of active service with the Partnership. The Partnership may, at its
discretion, waive in whole or in part such notice by paying the Executive,
following his last day of active service, his Base Salary during the balance of
such sixty (60) day period in lieu to the Executive on the Partnership’s regular
payroll dates.  This payment of Base Salary in lieu of notice is
intended to be exempt from Code Section 409A under Treasury Regulation Section
1.409A-1(b)(4).

        

      
        	
              	
                (b)

              	
                Cause

              

      

      

      "Cause"
is defined as any of the following:

      

      (a)
conviction of, or plea of nolo contendere to, a felony;

      

      (b)
participation in a fraud against the Partnership;

      (c)
participation in an act of dishonesty against the Partnership intended to result
in your personal enrichment;

      

      (d)
willful material breach of the Partnership's written policies;

      

      (e)
intentional significant damage to the Partnership's property by
you;

      
        
           

        

        
          4

          
            

          

        

        
           

        

      

      (f)
material breach of this Agreement; or

      

      (g)
conduct by you that, in the good faith and reasonable determination of the
Board, demonstrates gross unfitness to serve provided that in such event, the
Partnership shall provide notice to you describing the nature of the gross
unfitness and you shall thereafter have ten (10) days to cure such gross
unfitness if such gross unfitness is capable of being cured.

      

      The
Partnership may not terminate your employment for Cause unless and until you
receive a copy of a resolution duly adopted by the affirmative vote of at least
a majority of the Board of Directors of the Gran Tierra ("Board") finding that
in the good faith opinion of the Board, that "Cause" exists and specifying the
particulars thereof in reasonable detail.

       

      9.2 Termination by Partnership without
Cause

       

      The
Partnership may terminate the Executive’s employment without Cause at any
time.  If such termination constitues a “separation from service” (as
defined under Treasury Regulation Section 1.409A-1(h)), and provided the
Executive executes and allows to become effective the Company’s standard form of
release of claims within thirty (30) days following the separation from service,
the Partnership will pay the Executive cash severance (the “Separation Package”) equal to
one years’ Total Cash Compensation in a lump sum on the date that is thirty (30)
days after the separation from service.

        

      “Total
Cash Compensation” is defined as the annualized amount of Base Salary plus Bonus
Payment for the prior 12-month period.

        

      9.3 Termination by the Executive for Good
Reason

       

      Should
the Executive terminate his employment for Good Reason, as hereinafter defined,
and provided such termination constitues a separation from service, and provided
further that the Executive executes and allows to become effective the
Partnership’s standard form of release of claims within thirty (30) days
following the separation from service, the Partnership will pay the Executive
the Separation Package set out in section 9.2 in a lump sum on the date that is
thirty (30) days after the separation from service.  Failure of the
Executive to terminate his employment in a manner that constitutes a separation
from service effective not later than forty days (40) after the occurrence of any
event which would constitute Good Reason shall constitute waiver of his right
under this section 9.3 as to such triggering event.  Executive may
terminate his employment for Good Reason so long as Executive tenders his
resignation to the Partnership within thirty (30) days after the occurrence of
the event that forms the basis for the resignation for Good Reason; provided,
however, that Executive must provide written notice to the Partnership and Gran
Tierra describing the nature of the event that Executive believes forms the
basis for the resignation for Good Reason, and the Partnership and Gran Tierra
shall thereafter have ten (10) days to cure such event.

      

      “Good
Reason” is defined as the occurrence of any of the following without the
Executive’s express written consent:

                (a)

              	
                an
      adverse change in the Executive’s position, titles, duties or
      responsibilities (including new, additional or changed formal or informal
      reporting responsibilities) or any failure to re-elect or re-appoint him
      to any such positions, titles, duties or offices, except in connection
      with the termination of his employment for
  Cause;

              

      

      

      
        	
                 
      

              	
                (b)

              	
                a
      reduction by the Partnership of the Executive’s Base Salary except to the
      extent that the annual base salaries of all other executive officers of
      the Partnership or Gran Tierra are similarly reduced or any change in the
      basis upon which the Executive’s annual compensation is determined or paid
      if the change is or will be adverse to the Executive except that an award
      of annual performance bonuses by Gran Tierra’s Compensation Committee (and
      approved by the Board of Directors of Gran Tierra) are discretionary and
      in no instance shall be considered adverse to Executive if such
      performance bonus is reduced from a prior year or if an annual performance
      bonus is not paid;

              

      

      

      
        	
                 
      

              	
                (c)

              	
                a
      Change in Control (as defined below) of Gran Tierra occurs;
    or

              

      

      

      
        	
                 
      

              	
                (d)

              	
                any
      breach by the Partnership of any material provision of this
      Agreement.

              

      

      

      A “Change
in Control” is defined as:

      

      (a) a
dissolution, liquidation or sale of all or substantially all of the assets of
Gran Tierra;

      

      (b) a
merger or consolidation in which Gran Tierra is not the surviving
corporation;

      

      (c) a
reverse merger in which Gran Tierra is the surviving corporation but the shares
of Gran Tierra’s common stock outstanding immediately preceding the merger are
converted by virtue of the merger into other property, whether in the form of
securities, cash or otherwise; or

      

      (d) the
acquisition by any person, entity or group within the meaning of Section 13(d)
or 14(d) of the Exchange Act, or any comparable successor provisions (excluding
any employee benefit plan, or related trust, sponsored or maintained by Gran
Tierra or any affiliate of Gran Tierra) of the beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable
successor rule) of securities of Gran Tierra representing at least fifty percent
(50%) of the combined voting power entitled to vote in the election of
directors.

      9.4           Section 409A.  Application of Internal Revenue Code
Section 409A.   If the Partnership (or, if applicable, the
successor entity thereto) determines that the Separation Package and/or any
other termination payments and benefits provided under this Agreement or
otherwise (the “Payments”)
constitute “deferred compensation” under Code Section 409A (together, with any
state law of similar effect, “Section
409A”) and Executive is a “specified employee” (as such term is defined
in Section 409A(a)(2)(B)(i)) of the Partnership or any successor entity thereto
upon his separation from service, then, solely to the extent necessary to avoid
the incurrence of the adverse personal tax consequences under Section 409A as a
result of the payment of compensation upon his separation from service, the
timing of the Payments shall be delayed as follows:  on the earlier to
occur of (i) the date that is six months and one day after the date of the
separation from service or (ii) the date of Executive’s death (such earlier
date, the “Delayed Initial
Payment Date”), the Partnership (or the successor entity thereto, as
applicable) shall (A) pay to Executive a lump sum amount equal to the sum of the
Payments that Executive would otherwise have received through the Delayed
Initial Payment Date if the commencement of the payment of the Payments had not
been delayed pursuant to this paragraph and (B) commence paying the balance of
the Payments in accordance with the applicable payment schedules set forth
above.  Notwithstanding the foregoing, it is intended that each
installment of the Payments provided under this Agreement is a separate
“payment” for purposes of Section 409A and that the Payments are exempt from
Section 409A under Treasury Regulation Section
1.409A-1(b)(4).   This Agreement is intended to be interpreted to
the greatest extent possible as providing for payments that are exempt from, or,
if that is not possible, compliant with, the provisions of Section 409A.

      NON-COMPETITION
AND CONFIDENTIALITY

       

      11.1 Non-Competition

       

      The
Executive recognizes and understands that in performing the duties and
responsibilities of his employment as outlined in this Agreement, he will be a
key employee of Partnership and will occupy a position of high fiduciary trust
and confidence, pursuant to which he has developed and will develop and acquire
wide experience and knowledge with respect to all aspects of the services and
businesses carried on by Gran Tierra and its Member Companies and the manner in
which such businesses are conducted. It is the expressed intent and agreement of
the Executive and of Partnership that such knowledge and experience shall be
used solely and exclusively in the furtherance of the business interests of Gran
Tierra and its Member Companies and not in any manner detrimental to them. The
Executive therefore agrees that so long as he is employed by the Partnership
pursuant to this Agreement he shall not engage in any practice or business in
competition with the business of Gran Tierra or any of its Member
Companies.

       

      11.2 Confidentiality

       

      The
Executive further recognizes and understands that in the performance of his
employment duties and responsibilities as outlined in this Agreement, he will be
a key employee of the Partnership and will become knowledgeable, aware and
possessed of all confidential and proprietary information, know-how, data,
strategic studies, techniques, knowledge and other confidential information of
every kind or character relating to or connected with the business or corporate
affairs and operations of Gran Tierra and its Member Companies and includes,
without limitation, geophysical studies and data, market data, engineering
information, shareholder data, client lists, compensation rates and methods and
personnel information (collectively “Confidential Information”)
concerning the business of Gran Tierra and its Member Companies. The Executive
therefore agrees that, except with the consent of the Board, he will not
disclose such Confidential Information to any unauthorized persons so long as he
is employed by Partnership pursuant to this Agreement and for a period of 24
months thereafter; provided that the foregoing shall not apply to any
Confidential Information which is or becomes known to the public or to the
competitors of Gran Tierra or its Member Companies other than by a breach of
this Agreement.

       

      11.3 Following Termination of
Agreement

       

      Subject
to this provision and without otherwise restricting the fiduciary obligations
imposed upon, or otherwise applicable to the Executive as a result of the

Executive shall not be prohibited from obtaining employment with or otherwise
forming or participating in a business competitive to the business of Gran
Tierra and its Member Companies after termination of this Agreement and the

without the Company being obligated to provide the Executive with advance notice
of termination or pay in lieu of such notice, whether under contract, statute,
common law or otherwise, in the following circumstances:

     

    
      	
               
      

            	
              (a)

            	
              Voluntary
      Resignation

            

    

     

    In the
event the Executive voluntarily resigns, except where the Executive resigns for
Good Reason as provided for in this Agreement, the Executive will give a minimum
of sixty (60) days’ advance written notice to the Company.  The
Executive will not be entitled to receive any further compensation or benefits
whatsoever other than those which have accrued up to the Executive’s last day of
active service with the Company. The Company may, at its discretion, waive in
whole or in part such notice by paying the Executive, following his last day of
active service, his Base Salary during the balance of such sixty (60) day period
in lieu to the Executive on the Company’s regular payroll dates.  This
payment of Base Salary in lieu of notice is intended to be exempt from Code
Section 409A under Treasury Regulation Section 1.409A-1(b)(4).

     

    
      	
               
      

            	
              (b)

            	
              Cause

            

    

     

    "Cause"
is defined as any of the following:

    

    (a)
conviction of, or plea of nolo contendere to, a felony;

    

    (b)
participation in a fraud against the Company;

    

    (c)
participation in an act of dishonesty against the Company intended to result in
your personal enrichment;

    

    (d)
willful material breach of the Company's written policies;

    

    (e)
intentional significant damage to the Company's property by you;

    

    (f)
material breach of this Agreement; or

     

    
      
        
        

      

      
        4.

        
          

        

      

      
        
        

      

    

     

    (g)
conduct by you that, in the good faith and reasonable determination of the
Board, demonstrates gross unfitness to serve provided that in such event, the
Company shall provide notice to you describing the nature of the gross unfitness
and you shall thereafter have ten (10) days to cure such gross unfitness if such
gross unfitness is capable of being cured.

    

    The
Company may not terminate your employment for Cause unless and until you receive
a copy of a resolution duly adopted by the affirmative vote of at least a
majority of the Board of Directors of the Company ("Board") finding that in the
good faith opinion of the Board, that "Cause" exists and specifying the
particulars thereof in reasonable detail.

     

    9.2           Termination
by the Company without Cause

     

    The
Company may terminate the Executive’s employment without Cause at any
time.  If such termination constitues a “separation from service” (as
defined under Treasury Regulation Section 1.409A-1(h)), and provided the
Executive executes and allows to become effective the Company’s standard form of
release of claims within thirty (30) days following the separation from service,
the Company will pay the Executive cash severance (the “Separation Package”) equal to
two years’ Total Cash Compensation in a lump sum on the date that is thirty (30)
days after the separation from service.

     

    “Total
Cash Compensation” is defined as the annualized amount of Base Salary plus Bonus
Payment for the prior 12-month period.

     

    9.3           Termination
by the Executive for Good Reason.

     

    Should
the Executive terminate his employment for Good Reason, as hereinafter defined,
and provided such termination constitues a separation from service, and provided
further that the Executive executes and allows to become effective the Company’s
standard form of release of claims within thirty (30) days following the
separation from service, the Company will pay the Executive the Separation
Package set out in section 9.2 in a lump sum on the date that is thirty (30)
days after the separation from service.  Failure of the Executive to
terminate his employment in a manner that constitutes a separation from service
effective not later than forty days (40) after the occurrence of any event which
would constitute Good Reason shall constitute waiver of his right under this
section 9.3 as to such triggering event.  Executive may terminate his
employment for Good Reason so long as Executive tenders his resignation to the
Company within thirty (30) days after the occurrence of the event that forms the
basis for the resignation for Good Reason; provided, however, that Executive
must provide written notice to the Company describing the nature of the event
that Executive believes forms the basis for the resignation for Good Reason, and
the Company shall thereafter have ten (10) days to cure such event.

     

    “Good
Reason” is defined as the occurrence of any of the following without the
Executive’s express written consent:

     

    
      
        
        

      

      
        5.

        
          

        

      

      
        
        

      

    

     

    
      	
               
      

            	
              (a)

            	
              an
      adverse change in the Executive’s position, titles, duties or
      responsibilities (including new, additional or changed formal or informal
      reporting responsibilities) or any failure to re-elect or re-appoint him
      to any such positions, titles, duties or offices, except in connection
      with the termination of his employment for
  Cause;

            

    

    

    
      	
               
      

            	
              (b)

            	
              a
      reduction by the Company of the Executive’s Base Salary except to the
      extent that the annual base salaries of all other executive officers of
      the Company are similarly reduced or any change in the basis upon which
      the Executive’s annual compensation is determined or paid if the change is
      or will be adverse to the Executive except that an award of annual
      performance bonuses by the Company’s Compensation Committee (and approved
      by the Board of Directors) are discretionary and in no instance shall be
      considered adverse to Executive if such performance bonus is reduced from
      a prior year or if an annual performance bonus is not
  paid;

            

    

    

    
      	
               
      

            	
              (c)

            	
              a
      Change in Control (as defined below) of the Company occurs;
    or

            

    

    

    
      	
               
      

            	
              (d)

            	
              any
      breach by the Company of any material provision of this
      Agreement.

            

    

    

    A “Change
in Control” is defined as:

    

    (a) a
dissolution, liquidation or sale of all or substantially all of the assets of
the Company;

    

    (b) a
merger or consolidation in which the Company is not the surviving
corporation;

    

    (c) a
reverse merger in which the Company is the surviving corporation but the shares
of the Company’s common stock outstanding immediately preceding the merger are
converted by virtue of the merger into other property, whether in the form of
securities, cash or otherwise; or

    

    (d) the
acquisition by any person, entity or group within the meaning of Section 13(d)
or 14(d) of the Exchange Act, or any comparable successor provisions (excluding
any employee benefit plan, or related trust, sponsored or maintained by the
Company or any affiliate of the Company) of the beneficial ownership (within the
meaning of Rule 13d-3 promulgated under the Exchange Act, or comparable
successor rule) of securities of the Company representing at least fifty percent
(50%) of the combined voting power entitled to vote in the election of
directors.

     

    
      
        
        

      

      
        6.

        
          

        

      

      
        
        

      

    

     

    9.4       Section 409A.  Application of Internal Revenue Code
Section 409A.  If the Company (or, if applicable, the successor
entity thereto) determines that the Separation Package and/or any other
termination payments and benefits provided under this Agreement or otherwise
(the “Payments”)
constitute “deferred compensation” under Code Section 409A (together, with any
state law of similar effect, “Section
409A”) and Executive is a “specified employee” (as such term is defined
in Section 409A(a)(2)(B)(i)) of the Company or any successor entity thereto upon
his separation from service, then, solely to the extent necessary to avoid the
incurrence of the adverse personal tax consequences under Section 409A as a
result of the payment of compensation upon his separation from service, the
timing of the Payments shall be delayed as follows:  on the earlier to
occur of (i) the date that is six months and one day after the date of the
separation from service or (ii) the date of Executive’s death (such earlier
date, the “Delayed Initial
Payment Date”), the Company (or the successor entity thereto, as
applicable) shall (A) pay to Executive a lump sum amount equal to the sum of the
Payments that Executive would otherwise have received through the Delayed
Initial Payment Date if the commencement of the payment of the Payments had not
been delayed pursuant to this paragraph and (B) commence paying the balance of
the Payments in accordance with the applicable payment schedules set forth
above.  Notwithstanding the foregoing, it is intended that each
installment of the Payments provided under this Agreement is a separate
“payment” for purposes of Section 409A and that the Payments are exempt from
Section 409A under Treasury Regulation Section 1.409A-1(b)(4).  This
Agreement is intended to be interpreted to the greatest extent possible as
providing for payments that are exempt from, or, if that is not possible,
compliant with, the provisions of Section 409A.

    11.1        Non-Competition

     

    The
Executive recognizes and understands that in performing the duties and
responsibilities of his employment as outlined in this Agreement, he will be a
key employee of the Company and will occupy a position of high fiduciary
confidence, pursuant to which he has developed and will develop and acquire wide
experience and knowledge with respect to all aspects of the services and
businesses carried on by Gran Tierra and its Member Companies and the manner in
which such businesses are conducted.  It is the expressed intent and
agreement of Executive and of Gran Tierra that such knowledge and experience
shall be used solely and exclusively in the furtherance of the business
interests of Gran Tierra and its Member Companies and not in any manner
detrimental to them.  The Executive therefore agrees that so long as
he is employed by the Company pursuant to this Agreement he shall not engage in
any practice or business in competition with the business of Gran Tierra or any
of its Member Companies.

     

    11.2        Confidentiality

of all confidential and proprietary information, know-how, the strategic
studies, techniques, knowledge and other confidential information of every kind
or character relating to or connected with the business or corporate affairs and
operations of Gran Tierra and its Member Companies and includes, without
limitation, geophysical studies and data, market data, engineering information,
shareholder data, client lists, compensation rates and methods and personnel
information (collectively “Confidential Information”)
concerning the business of Gran Tierra and its Member Companies.  The
Executive therefore agrees that, except with the consent of the Board, he will
not disclose such Confidential Information to any unauthorized persons so long
as he is employed by the Company pursuant to this Agreement and for a period of
24 months thereafter; provided the foregoing shall not apply to any Confidential
Information which is or becomes known to the public or to the competitors of
Gran Tierra or its Member Companies other than by a breach of this
Agreement.
