            Market Value will be the closing price of the Shares on the business
            day immediately prior to the Award Date;

      (c)   if the Company's Shares trade on an organized trading facility
            outside of Canada, then the Market Value determined for that
            organized trading facility will be converted into Canadian dollars
            at a conversion rate determined by the Administrator having regard
            for the published conversion rates as of the Award Date;

      (d)   if the Company's Shares are listed on one or more organized trading
            facilities but have not traded on the Award Date, then the Market
            Value will be, subject to the necessary approvals of the applicable
            Regulatory Authorities, that value as is determined by resolution of
            the Board; and

      (e)   if the Company's Shares are not listed on an organized trading
            facility, then the Market Value will be, subject to the necessary
            approvals of the applicable Regulatory Authorities, that value as is
            determined by resolution of the Board.

3.6 Additional Terms

Subject to all applicable securities laws and regulations and the rules and
policies of all applicable Regulatory Authorities, the Board may attach other
terms and conditions to the grant of a particular Option, such terms and
conditions to be referred to in a schedule attached to the Option Certificate.

      (b)   providing that a portion or portions of an Option vest after certain
            periods of time or expire after certain periods of time; and

      (c)   providing that an Option be exercisable immediately, in full,
            notwithstanding that it has vesting provisions, upon the occurrence
            of certain events, such as a friendly or hostile takeover bid for
            the Company.

subdivided, converted, exchanged or reclassified or in any way substituted for
(collectively the "Event"), an Option, to the extent that it has not been
exercised, shall be adjusted by the Board in accordance with such Event in the
manner the Board deems appropriate. No fractional shares shall be issued upon
the exercise of the Options and accordingly, if as a result of the Event, an
Option Holder would become entitled to a fractional share, such Option Holder

certified cheque, bank draft or cheque from a Toronto Stock Exchange member
broker firm payable to "Optima Petroleum Corporation" in an amount equal to the
