SCHEDULE A
 POLICY RESPECTING CONFIDENTIALITY, DISCLOSURE AND TRADING BY  RESTRICTED PERSONS AND EMPLOYEES
 PART I CONFIDENTIALITY
 1.
    
    Purpose1.0
    
    The purpose of Part I of this Policy is to ensure that all employees and directors of OSI
Geospatial Inc. and its subsidiaries (the Company), regardless of country of residence,
treat confidential information in a consistent manner and in accordance with Canadian
securities laws.2.
    
    Confidential Information2.0
    
    Information respecting the Company is considered confidential information if its knowledge
would reasonably be expected to result in a significant change in the market price or value of
the Company securities, and such information has not been publicly disclosed (throughout this
Policy, Confidential Information).2.1
    
    Confidential Information includes information concerning the business operations or capital
of the Company.2.2
    
    It is to be recognized that information may be Confidential Information within the meaning of
this Policy at an earlier stage than the Company is required by applicable securities laws to
publicly disclose such information (for example at an earlier stage in the process of making a
major acquisition or negotiating a significant contract).2.3
    
    Where information is disseminated by the Company through a press release, that information is
not considered to be publicly disclosed until at least the close of one (1) complete business
day after the press release, and in circumstances where the information is not readily
accessible through the news media, that information may not be considered to be publicly
disclosed until up to a week.3.
    
    Safeguarding Confidentiality3.0
    
    The Company personnel may not discuss Confidential Information with any other persons
(whether or not Company personnel), except in the necessary course of business.3.1
    
    In addition, information disclosed by a customer, supplier or business associate to the
Company personnel, and identified as private or confidential, shall be protected from
disclosure to the same extent as would Confidential Information.3.2
    
    To protect Confidential Information from disclosure, the Company personnel:

an exposed manner in public places;iii)

 3.3
    
    Before any meeting with other persons where Confidential Information may be disclosed, the

Information other than in the necessary course of business, or trade in the Company securities
until the Confidential Information is generally disclosed.3.4
    
    When so required by a supervisor, the Company personnel will take such additional steps as
may be necessary to protect Confidential Information from disclosure, including keeping filing
cabinets locked, referring to specified matters only by a code name and limiting access to the
word processing system.3.5
    
    All inquiries from the media shall be referred to the Chief Executive Officer (CEO) (or such
other person as may be designated from time to time to perform the role of such officer under
this Policy by the CEO) for response by designated spokespersons.3.6
    
    All inquiries from securities analysts or institutional investors shall be referred to the
CEO (or such other person as may be designated from time to time to perform the role of such
officer under this Policy by the CEO) for response by designated spokespersons.4.

    Failure to comply with the terms of this Part of the Policy will result in disciplinary
action, possibly including termination of employment.4.1
