Step 3 Order Details

Enter the type of order you would like to place. Depending on the type of transaction you are entering,you may be able to choose between the following:

Sell Exercises

Market Order: Sell a security immediately, at the best possible price.

Limit Order: Sell a security at a specified price. The order can be executed only at the specified price orbetter, and can be set to expire after a specified date (typically up to 30 days) if the order is notcompleted.

Sell to Cover Exercises

If you are performing a transaction whereby you are selling shares to cover the costs associated withyour transaction, your order will automatically be completed as a market order. Shareworks calculatestheminimum number of shares to be sold to cover the cost of the exercise (plus applicable taxes andfees).

If your company permits, you can choose to increase the number of shares to be sold to receiveadditional cash proceeds.

Participant Exercise GuideFor Participants of Canadian Issuers 10

The number of shares to be sold cannot be decreased as there must be a buffer for market volatility toensure enough funds are raised to pay for the exercise cost, fees and taxes (where applicable).

Cash Exercises (hold exercises)

If you are holding your shares and are paying for any associated costs separately, you will not see theOrder Details screen during your exercise process.

Note the Estimated Proceeds panel on the right hand side of your screen. This breakdown isupdated with real time information to provide you with the most up to date estimate. However,actual proceeds may vary depending on actual prices of the fair market value of the exerciseand any sale order.
