SCHEDULE A

Series 1 Shares

Terms which are capitalized and used herein and defined in the Senior Secured Credit Agreement shall have the meanings ascribed thereto in the Senior Secured Credit Agreement; and the following terms have the following meanings:

Until the Cessation Date, the holders of the Series 1 Shares will be entitled to receive notice of and attend all meetings of shareholders of the Corporation and to vote at such meetings only on the basis set out in this paragraph 2.

The holders of the Series 1 Shares shall have as a series the right, voting exclusively and separately as a series, on the basis of one (1) vote per Series 1 Share, to nominate and elect two (2) of the directors of the Corporation.

At any meeting of holders of Series 1 Shares as a series (or of holders of the Class A Preference shares as a class), each such holder shall be entitled to one (1) vote per Series 1 Share; but the holders of the Series 1 Shares shall not have any other voting rights except as expressly provided herein or as provided under the Act.

The holders of the Series 1 Shares, as such, will not be entitled to receive dividends.

Subject to the Act and upon giving notice as hereinafter provided, the Corporation may redeem all (but not less than all) of the outstanding Series 1 Shares at any time after the Cessation Date, and such redemption shall entitle the holders of the Series 1 Shares to the Redemption Amount per share.

Unless all the holders of the Series 1 Shares to be redeemed have waived the notice period in writing in respect of a redemption of the Series 1 Shares by the Corporation, the Corporation shall give not less than ten (10) days’ notice in writing of the redemption by mailing such notice to the registered holders of the Series 1 Shares, specifying the date and place or places of redemption.

2 of 7

If notice of the redemption is given by the Corporation in the manner aforesaid and an amount sufficient to redeem the Series 1 Shares is deposited with any trust company or chartered bank in Canada, as specified in the notice, on or before the redemption date, the Series 1 Shares shall be deemed to be redeemed on the redemption date and the holders thereof shall thereafter have no rights against the Corporation in respect thereof except, upon surrender of the certificate or certificates for such Series 1 Shares, to receive payment therefor out of the moneys so deposited. Any interest earned on any such deposit shall belong to the Corporation.

In the event of the liquidation, dissolution or winding up of the Corporation or other distribution of the property or assets of the Corporation among its shareholders for the purpose of winding-up its affairs, whether voluntarily or involuntarily, the holders of the Series 1 Shares shall be entitled, for each such share held by such holder, to receive out of the property and assets of the Corporation, before any amount shall be paid or any property or assets of the Corporation distributed to the holders of the common shares, Class B Preference shares or any other shares of the Corporation ranking after the Series 1 Shares, the Redemption Amount.

After payment to the holders of the Series 1 Shares of the amount provided above, they shall not be entitled, as such, to share in any further distribution of the property or assets of the Corporation.

So long as any of the Series 1 Shares are outstanding, the Corporation shall not, without the approval of the holders of the Series 1 Shares, create any additional Series 1 Shares.

In addition to the requirements of the Act, the rights, privileges, restrictions and conditions attaching to the Series 1 Shares may only be amended or modified with the prior approval of all the holders of the Series 1 Shares.

The Corporation may, at any time and from time to time, purchase for cancellation the whole or any part of the Series 1 Shares at the lowest price at which, in the opinion of the directors, such shares are obtainable, with the consent of those holders of Series 1 Shares whose shares the Corporation is proposing to purchase (which consent may be unreasonably withheld); provided however that notwithstanding the foregoing all Series 1 Shares shall be purchased if so required pursuant to and in accordance with section 3.1.4 of the conversion and voting agreement made as of June 25, 2012 between the Corporation and Tenor KRY Coöperatief U.A.

The holders of the Special LAC Shares will be entitled to receive notice of and attend all meetings of shareholders of the Corporation and to vote at such meetings only on the basis set out in this paragraph 2.

The holders of the Special LAC Shares shall have:

4 of 7

The holders of the Special LAC Shares and the holders of the common shares shall be entitled to share, pari passu, in any dividends, as and when declared by the Board of Directors, on the basis that the holders of the Special LAC Shares will be entitled to receive an amount per share equal to one one-thousandth of a percent (0.001%) of the aggregate amount of any dividend declared, and the holders of the common shares will be entitled to receive the remaining amount of such dividend. No dividend shall be declared or paid on the common shares or the Special LAC Shares unless a dividend is also declared or paid, as the case may be, on the other of them at the same time on the basis set out above.

The Corporation shall not have any right to redeem any of the Special LAC Shares.

The holders of the Special LAC Shares will have the right, at their sole option, exercisable at any time and from time to time from and after September 1, 2012 (but not before such date), to convert each Special LAC Share into that number of common shares as is represented by ‘N’, determined by the following formula:

Upon the exercise of the foregoing right of conversion, the stated capital accounts maintained for each of the Special LAC Shares and the common shares shall be adjusted in the manner required by the Act. The conversion right provided for in this paragraph may be exercised by notice in writing given to the Corporation at the registered office of the Corporation, accompanied by the certificate or certificates representing the Special LAC Shares to be converted in respect of which the holder thereof desires to exercise such right of conversion and such notice shall be executed by the person registered on the books of the Corporation as the holder of such Special LAC Shares to be converted in respect of which such right is being exercised or by such holder’s duly authorized attorney and shall specify the number

5 of 7

of Special LAC Shares which the holder desires to have converted. As soon as practicable from receipt of such notice and in any event within three (3) Business Days thereof, the Corporation shall issue certificates representing the converted shares upon the basis above prescribed and in accordance with the provisions hereof to the registered holder of the Special LAC Shares to be converted represented by the certificate accompanying such notice. If less than all of the Special LAC Shares held by the holder exercising its, his or her right hereunder represented by any certificate are to be converted, such holder shall be entitled to receive a new certificate for the Special LAC Shares representing the Special LAC Shares comprised in the original certificate which are not to be converted. All converted shares resulting from any conversion provided for herein shall be fully paid and non-assessable. The Corporation shall not be required upon the exercise of any right of conversion to issue fractional common shares in satisfaction of its obligations hereunder, and in such circumstance the number of common shares issued shall be rounded upward and no payment shall be made on account of any such fractional interest in a common share.

In the event of the liquidation, dissolution or winding up of the Corporation or other distribution of the property or assets of the Corporation among its shareholders for the purpose of winding-up its affairs, whether voluntarily or involuntarily, the holders of the Special LAC Shares shall be entitled, for each such share held by such holder, to receive out of the property and assets of the Corporation, before any amount shall be paid or any property or assets of the Corporation distributed to the holders of the common shares or any other shares of the Corporation ranking after the Special LAC Shares, $0.01 per share.

Thereafter, the holders of the Special LAC Shares and the holders of the common shares shall be entitled to share, pari passu, in any distribution of the remaining assets of the Corporation on the basis that the holders of the Special LAC Shares will be entitled to receive an amount per share equal to one one-thousandth of a percent (0.001%) of the aggregate amount of the assets available for distribution to the holders of the Special LAC Shares and the common shares, and the holders of the common shares will be entitled to receive the remaining amount of such assets. No distribution of the remaining assets shall be made to the holders of the common shares or the Special LAC Shares unless a distribution is also made to the other of them at the same time on the basis set out above.

So long as any of the Special LAC Shares are outstanding, the Corporation shall not, without the approval of the holders of the Special LAC Shares, create any additional Special LAC Shares.

The Corporation may, at any time and from time to time, purchase for cancellation the whole or any part of the Special LAC Shares at the lowest price at which, in the opinion of the directors, such shares are obtainable, with the consent of those holders of Special LAC Shares whose shares the Corporation is proposing to purchase (which consent may be unreasonably withheld); provided however that notwithstanding the foregoing all Special LAC Shares shall be purchased if so required pursuant to and in accordance with section 2.4 or 3.1.4 of the conversion and voting agreement made as of June 25, 2012 between the Corporation and Tenor KRY Coöperatief U.A.
