INSTRUCTIONS FOR PREPARATION OF VOTING INSTRUCTION FORMS

This sample Voting Instruction Form is provided for informational purposes for direct mailings to Non-Objecting Beneficial Owners (“NOBOs”).  It is the issuer’s responsibility to ensure that their Voting Instruction Form for NOBOs contains the information required by applicable regulations and securities laws and that it matches the proxy for wording and numbering of resolutions.  Pacific Corporate Trust Company will not accept responsibility for any deficiencies in the wording or content of this sample Voting Instruction Form.

1.

Once you have selected and downloaded this document from our website, you will be viewing it with your web browser.  In order to open the document in MS WORD, select “File” and “Save As”.  Save the file with the name of your choice in the location of your choice.  Then reopen the document using MS WORD.  

2.

Because of the landscape format of the VIF, page 1 of the form (currently page 2 of this document) has been set up as two columns with a column break inserted above the address box on the left.   Click on “VIEW” and select “PRINT LAYOUT” to view the VIF in column format. To view all of the formatting codes within the VIF on the screen, click on ^¶ on the main toolbar.  Note that you can select “File” and “Print Preview” at any time to see how your document will look once it is printed.

3.

This document is currently protected from making changes, except for the meeting information form fields at the top left on page 1 of the form (type of meeting, issuer name, date, time and location) and the CSR’s name on page 2.  To customize each of these form fields now, use the TAB key or your mouse to move between them and enter the information specific to the applicable meeting.

4.

Now unprotect the document to make any remaining changes and to customize the resolutions table for this meeting.  To do this, select “TOOLS” and “UNPROTECT DOCUMENT”.  BC Companies using this proxy for an Annual meeting may combine resolution numbers 2 and 3.  IMPORTANT:  The remaining wording on the left side of this form and the reverse of the form is standard and should not be changed.  Also, the address box on the front page, at the bottom left side must remain in this exact position and at this exact size.  This box is used by the mailing house to print the NOBO’s name, address, financial institution and electronic voting codes directly onto the form, so that it will be visible when inserted into a 9” x 12” window envelope along with the accompanying meeting materials.  If you need to make extensive changes to the form, please ensure that this required box is not deleted, moved or resized.

5.

The Resolutions have been prepared in a TABLE FORMAT and inserted into the right column.  Please leave them in TABLE FORMAT as it allows for smooth and unaltered conversion into PDF format prior to SEDAR filing.  Automatic Paragraph Numbering (“FORMAT”, then “BULLETS AND NUMBERING”) has also been used so if you wish to amend a resolution, go to the text of the resolution and make your changes.  If you wish to insert an entirely new resolution using the mouse, place the cursor at the beginning of the row below which you wish to insert a new resolution, click on “TABLE”, select “INSERT” and then “ROWS BELOW”.  The new row will be automatically numbered with the next consecutive number, and the existing rows being automatically re-numbered.  You may then type in your new resolution.

6.

“N/A” must be inserted in either the “Against” or “Withhold” column, whichever option is not allowed for the applicable resolution.

7.

Delete any unneeded sample resolutions left on the VIF.  If there are more than 22 resolutions for this meeting, add new resolutions after #22 by hitting the TAB key from the WITHHOLD column of #22.

8.

PAGE 2 of this VIF is also set up in LANDSCAPE, but without columns.  The wording is standard and should not be changed except for the voting methods, at the bottom of this page if necessary (e.g., the Telephone and Internet voting methods should be deleted if security holders are not being given these options).

9.

Print and delete this instruction page before printing your VIFs.

10.

Save your changes when you are satisfied with them.

11.

Print your Voting Instruction Forms double-sided and on BLUE PAPER to distinguish them from the proxies for the registered securityholders.
