THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “U.S. SECURITIES ACT”), OR ANY STATE SECURITIES LAWS. THE HOLDER HEREOF, BY PURCHASING THESE SECURITIES, AGREES FOR THE BENEFIT OF [ISSUER] THAT SUCH SECURITIES MAY BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED ONLY: (A) TO [ISSUER], (B) OUTSIDE THE UNITED STATES IN ACCORDANCE WITH RULE 904 OF REGULATION S UNDER THE U.S. SECURITIES ACT (“REGULATION S”), (C) IN ACCORDANCE WITH (1) RULE 144A UNDER THE U.S. SECURITIES ACT, IF AVAILABLE, OR (2) RULE 144 UNDER THE U.S. SECURITIES ACT, IF AVAILABLE, (D) UNDER AN EFFECTIVE REGISTRATION STATEMENT UNDER THE U.S. SECURITIES ACT, OR (E) IN ANOTHER TRANSACTION THAT DOES NOT REQUIRE REGISTRATION UNDER THE U.S. SECURITIES ACT, AND IN EACH CASE IN ACCORDANCE WITH APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES; PROVIDED THAT IN THE CASE OF TRANSFERS PURSUANT TO (C)(2) OR (E) ABOVE, A LEGAL OPINION SATISFACTORY TO [ISSUER] MUST FIRST BE PROVIDED.

provided that, if the Underlying Shares are being sold outside of the United States in accordance with Rule 904 of Regulation S at a time when Issuer is a “foreign issuer” as defined in Rule 902 of Regulation S, the legend may be removed by providing a duly completed and signed declaration to Issuer’s transfer agent for the Underlying Shares, or such other organization or entity performing such functions for Issuer (the “Transfer Agent”) to the following effect (or as the Issuer may from time to time prescribe) and, if required by the Transfer Agent, an opinion of counsel of recognized standing satisfactory to the Transfer Agent, acting reasonably, that such legend is no longer required under the applicable requirements of the U.S. Securities Act:

“The undersigned seller (i) acknowledges that the sale of the securities of [Issuer] to which this declaration relates is being made in reliance on Rule 904 of Regulation S (“Regulation S”) under the United States Securities Act of 1933, as amended (the “U.S. Securities Act”) and (ii) certifies that: (A) it is not an affiliate (as defined in Rule 405 under the U.S. Securities Act) of [Issuer]; (B) the offer of the securities was not made to a person in the United States and either (1) at the time the buy order was originated, the buyer was outside the United States, or the seller and any person acting on its behalf reasonably believed that the buyer was outside the United States, or (2) the transaction was executed on or through the facilities of the TSX, and neither the seller nor any person acting on its behalf knows that the transaction has been prearranged with a buyer in the United States; (C) neither the seller nor any affiliate of the seller nor any person acting on any of their behalf has engaged or will engage in any “directed selling efforts” (as such term is defined in Regulation S) in the United States in connection with the offer and sale of the securities; (D) the sale is bona fide and not for the purpose of “washing off” the resale restrictions imposed because the securities are “restricted securities” (as that term is defined in Rule 144(a)(3) under the U.S. Securities Act); (E) the seller does not intend to replace the securities sold in reliance on Rule 904

8

of Regulation S with fungible unrestricted securities; and (F) the contemplated sale is not a transaction, or part of a series of transactions which, although in technical compliance with Regulation S, is part of a plan or scheme to evade the registration provisions of the U.S. Securities Act.”;

and provided further, that if any Underlying Shares are being sold to a purchaser in the United States in accordance with Rule 144 under the U.S. Securities Act, the legend may be removed by delivery to the Transfer Agent of an opinion of counsel of recognized standing, satisfactory to the Issuer, acting reasonably, to the effect that the legend is no longer required under applicable requirements of the U.S. Securities Act;

(ii)           the certificates representing Notes also will bear the following legend denoting the restrictions on transfer under Applicable Securities Laws (including, but not limited to, National Instrument 45-102 — Resale of Securities):

UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS SECURITY MUST NOT TRADE THE SECURITY OR ANY COMMON SHARES ISSUED ON A CONVERSION OF ANY PRINCIPAL AMOUNT OF THIS SECURITY (OR INTEREST THEREON)  BEFORE [INSERT THE DATE THAT IS FOUR MONTHS AND A DAY AFTER THE DISTRIBUTION DATE OF NOTES].

and, if at the date of the conversion of Notes the applicable restriction period has not expired, the certificates representing the Underlying Shares will bear such legend as well; and

(iii)          in addition to the foregoing legends, the certificates representing the Underlying Shares shall, until the date that is four months and a day after the Closing Date, bear, in addition to any legend(s) required by Canadian securities laws and policies, the following legend:

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE LISTED ON THE TORONTO STOCK EXCHANGE (“TSX”); HOWEVER, SAID SECURITIES CANNOT BE TRADED THROUGH THE FACILITIES OF THE TSX SINCE THEY ARE NOT FREELY TRANSFERABLE, AND CONSEQUENTLY ANY CERTIFICATE REPRESENTING SUCH SECURITIES IS NOT “GOOD DELIVERY” IN SETTLEMENT OF TRANSACTIONS ON THE TSX.

(d)           the Subscriber will not sell, assign or transfer the Securities except in accordance with the provisions of Applicable Securities Laws and Exchange rules, if applicable, that are in effect as the time of such sale, assignment or transfer.

7.2   At any time when the Issuer is neither subject to and in compliance with Section 13 or 15(d) of the United States Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor exempt from the filing requirements of the Exchange Act pursuant to Rule 12g3-2(b) thereunder, the Issuer agrees to furnish holders and prospective purchasers of Notes with the information required by Rule 144A(d)(4) under the U.S. Securities Act.

7.3   The Subscriber also acknowledges that it has been advised to consult its own legal advisors with respect to applicable resale restrictions and that it is solely responsible (and the Issuer is not in any manner responsible) for complying with such restrictions.
