          As
the Superintendent will be employed on a full time basis and in a managerial
capacity for the Company, his hours of work will vary and may be irregular and

Superintendent, by the Company with or without cause, or by mutual agreement),
except with the written permission of an officer of the Company. The
Superintendent also agrees that the unauthorized disclosure of any such
information during the life of this agreement shall justify the immediate
termination of his or her employment.

          (3)

contained in the Confidentiality Agreement dated August 10, 2006 between the
Superintendent and the Company (the “Confidentiality Agreement”).

agreement absent such an inducement. Furthermore, the existence of any claim or
cause of action by the Superintendent against the Company, whether predicated on

unenforceable in any jurisdiction, the decision shall not affect any other
covenant or provision of this agreement or the application of any other covenant

of Employment

          (1)
The parties understand and agree that the Supervisor’s employment pursuant to
this agreement may be terminated as follows:

          (a)     
by the Supervisor, at any time, for any reason, on the giving of 30 days of
notice to the Company. The Company may waive notice, in whole or in part and if
it does so, the Supervisor’s entitlement to remuneration and benefits pursuant
to this agreement will cease on the date it waives such notice;

          (b)     
by the Company in its absolute discretion and for any reason on the giving of 30
days of notice to the Supervisor, or on paying to the Supervisor the equivalent
pay in lieu of notice. The payments contemplated in this clause include all
entitlement to either notice or pay in lieu of notice. The Supervisor agrees to
accept the notice (or pay in lieu of notice) as set out in this clause in full
and final settlement of all amounts owing to the Supervisor by the Company on
termination, including any payment in lieu of notice of termination, entitlement
of the Supervisor under any applicable statute and any rights which the
Supervisor may have at common law, and the Supervisor waives any claim to any
other payment or benefits from the Company; or

          (c)     
by the Company, in its absolute discretion, without any notice or pay in lieu
thereof, for “cause”. Cause includes, but is not limited to the following:

	 	(i) 	
      any material breach of the provisions of this
      agreement;

	 	(ii) 	
      any conduct of the Supervisor which tends to bring the
      Supervisor or the Company into disrepute;

	 	(iii) 	
      consistent poor performance by the Supervisor, after
      being advised as to the standard required;

	 	(iv) 	
      any intentional or grossly negligent disclosure by the
      Supervisor of the Company's Confidential Information;

	 	(v) 	
      conduct on the part of the Supervisor which is materially
      detrimental to the business or the financial position of the
    Company;

	 	(vi) 	
      the conviction of the Supervisor of a criminal offence
      punishable by indictment (where such cause is not prohibited by
    law);

	 	(vii) 	
      any breach of Lexington's or the Company's insider
      trading policy; and

	 	(viii) 	
      any and all omissions, commissions or other conduct which
      would constitute “cause” at law.

          (2)
The Supervisor’s employment shall also be terminated upon his or her death.

          (3)
The parties understand and agree that the giving of notice or the payment of pay

Supervisor’s employment shall not prevent the Company from alleging cause for
the termination.

shall not be entitled to receive any payment or compensation for loss of office
