The offer and sale of the Securities to any purchaser outside Yukon, and that is not resident in Yukon, is not subject to the prospectus requirements of the Securities Act (Yukon); and

(qq)

The Company has applied for an exemption from the requirements of Part 7 of the Business Corporations Act (Yukon) that would otherwise apply to the Company and the Indenture in connection with the offering, issue, sale and delivery of the Securities by the Company to the Purchasers, the distribution of the Securities by the Purchasers as contemplated by this Agreement and the issue and delivery of the Exchange Securities pursuant to the Exchange Offer.

Subject to the terms and conditions herein set forth, the Company agrees to issue and sell to each of the Purchasers, and each of the Purchasers agrees, severally and not jointly, to purchase from the Company, at a purchase price of 98.285% of the principal amount thereof, plus accrued interest, if any, from December 12, 2013 to the Time of Delivery hereunder, the principal amount of Securities set forth opposite the name of such Purchaser in Schedule I hereto.

Upon the authorization by you of the release of the Securities, the several Purchasers propose to offer the Securities for sale upon the terms and conditions set forth in this Agreement and the Offering Memorandum and each Purchaser, acting severally and not jointly, hereby represents and warrants to, and agrees with the Company that:

(a)

It will sell the Securities only to: (i) persons who it reasonably believes are “qualified institutional buyers” (“QIBs”) within the meaning of Rule 144A under the Act in transactions meeting the requirements of Rule 144A or, (ii) upon the terms and conditions set forth in Annex I to this Agreement;

(b)

It is an Institutional Accredited Investor (within the meaning of Rule 501 under the Act); and

(c)

It and each of its affiliates will not solicit offers to purchase or sell the Securities in any province or territory of Canada except on a private placement basis in accordance with the Final Offering Circular (including for the purposes hereof, any Canadian offering document appended thereto) and in compliance with Canadian Securities Laws to “accredited investors” as such term is used in National Instrument 45-106 – Prospectus and Registration Exemptions (“NI 45-106”) through a registrant properly registered or otherwise so as to not require the filing of a prospectus or any other document with respect to the distribution of the Securities under applicable Canadian Securities Laws (other than, if required by applicable Canadian Securities Laws, the filing of the Offering Memorandum (including for the purposes hereof, any Canadian offering document appended thereto) provided to purchasers in the Provinces and Form 45-106F1 pursuant to NI 45-106 or any equivalent form in any of the Provinces) and to provide such information as may reasonably be required by the Company in respect of the purchasers of the Securities in order for the Company to fulfill its filing obligations under applicable Canadian Securities Laws, if any. “Canadian Securities Laws” means the securities acts or similar statutes of each of the Provinces and the Yukon and all regulations, rules, policy statements, instruments, notices and blanket orders or rulings thereunder.

4.	(a)	The Securities to be purchased by each Purchaser hereunder will be represented by one or more definitive global Securities in book-entry form which will be deposited by or on behalf of the Company with The Depository Trust Company (“DTC”) or its designated custodian. The Company will deliver the Securities to Xxxxxxx, Xxxxx & Co., for the account of each Purchaser, against payment by or on behalf of such Purchaser of the purchase price therefor by wire transfer in Federal (same day) funds, by causing DTC to credit the Securities to the account of Xxxxxxx, Sachs & Co. at DTC. The Company will cause the certificates representing the Securities to be made available to Xxxxxxx, Xxxxx & Co. for checking at least twenty-four hours prior to the Time of Delivery (as defined below) at the office of Xxxxxx and Xxxxx, LLP, 0000 XxXxxxxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000 (the “Closing Location”). The time and date of such delivery and payment shall be 9:30 a.m., New York City time, on December 12, 2013 or such other time and date as Xxxxxxx, Xxxxx & Co. and the Company may agree upon in writing. Such time and date are herein called the “Time of Delivery”.

	(b)	The documents to be delivered at the Time of Delivery by or on behalf of the parties hereto pursuant to Section 8 hereof, including the cross-receipt for the Securities and any additional documents requested by the Purchasers pursuant to Section 8 hereof, will be delivered at such time and date at the Closing Location, and the Securities will be delivered at the office of DTC (or its designated custodian), all at the Time of Delivery. A meeting will be held at the Closing Location at 4:00 p.m., New York City time, on the New York Business Day next preceding the Time of Delivery, at which meeting the final drafts of the documents to be delivered pursuant to the preceding sentence will be available for review by the parties hereto. For the purposes of this Section 4, “New York Business Day” shall mean each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close.

		(iii) any Company Supplemental Disclosure Document, Purchaser Supplemental Disclosure Document or Permitted General Solicitation Material, the use of which has been consented to by the Company and Xxxxxxx, Sachs & Co., is listed as applicable on Schedule II(b), Schedule II(c) or Schedule II(d) hereto, respectively;

The Company covenants and agrees with the several Purchasers that the Company will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Company’s counsel and accountants in connection with the issue of the Securities and all other expenses in connection with the preparation, printing, reproduction and filing of the Preliminary Offering Memorandum and the Offering Memorandum and any amendments and supplements thereto and the mailing and delivering of copies thereof to the Purchasers and dealers; (ii) the cost of printing or producing any Agreement among Purchasers, this Agreement, the Indenture, the Securities, the Registration Rights Agreement, the Blue Sky Memorandum, closing documents (including any compilations thereof), Permitted General Solicitation Materials and any other documents in connection with the offering, purchase, sale and delivery of the Securities; (iii) all expenses in connection with the qualification of the Securities for offering and sale under state securities laws as provided in Section 5(b) hereof, including the fees and disbursements of counsel for the Purchasers in connection with such qualification and in connection with the Blue Sky and legal investment surveys; (iv) any fees charged by securities rating services for rating the Securities; (v) the cost of preparing the Securities; (vi) the fees and expenses of the Trustee and any agent of the Trustee and the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Securities; (vii) all costs and expenses incurred in connection with any “road show” presentation to potential purchasers of the Securities; and (viii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section. It is understood, however, that, except as provided in this Section, and Sections 9 and 12 hereof, the Purchasers will pay all of their own costs and expenses, including the fees of their counsel and transfer taxes on resale of any of the Securities by them.

The obligations of the Purchasers hereunder shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Company herein are, at and as of the date hereof and the Time of Delivery, true and correct, the condition that the Company shall have performed all of its obligations hereunder theretofore to be performed, and the following additional conditions:

(i)

(a)

The Company will indemnify and hold harmless each Purchaser against any losses, claims, damages or liabilities, joint or several, to which such Purchaser may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, any Company Supplemental Disclosure Document, any Permitted General Solicitation Material or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, and will reimburse each Purchaser for any legal or other expenses reasonably incurred by such Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written information furnished to the Company by any Purchaser through Xxxxxxx, Xxxxx & Co. expressly for use therein.

(b)

Each Purchaser, severally and not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the Offering Memorandum, or any amendment or supplement thereto, or any Company Supplemental Disclosure Document, any Permitted General Solicitation Material or arise out of or are based upon the omission or alleged omission to state therein a material fact or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Offering Memorandum, the Pricing Memorandum, the Pricing Disclosure Package, the Offering Memorandum or any such amendment or supplement, any Company Supplemental Disclosure Document or any Permitted General Solicitation Material, in reliance upon and in conformity with written information furnished to the Company by such Purchaser through Xxxxxxx, Sachs & Co. expressly for use therein; and each Purchaser will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c)

Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the contrary; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d)

If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Purchasers on the other from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by the Purchasers, in each case as set forth in the Offering Memorandum. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Purchasers on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Purchasers agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which the Securities purchased by it and distributed to investors were offered to investors exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Purchasers’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint.

(e)

The obligations of the Company under this Section 9 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to any affiliate, director or officer of each Purchaser and each person, if any, who controls any Purchaser within the meaning of the Act; and the obligations of the Purchasers under this Section 9 shall be in addition to any liability which the respective Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Company and to each person, if any, who controls the Company within the meaning of the Act.

10.

(a)

If any Purchaser shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, you may in your discretion arrange for you or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Purchaser you do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Securities, or the Company notifies you that it has so arranged for the purchase of such Securities, you or the Company shall have the right to postpone the Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Offering Memorandum, or in any other documents or arrangements, and the Company agrees to prepare promptly any amendments or supplements to the Offering Memorandum which in your opinion may thereby be made necessary. The term “Purchaser” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Securities.

(b)

If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Company as provided in subsection (a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Purchaser to purchase the principal amount of Securities which such Purchaser agreed to purchase hereunder and, in addition, to require each non-defaulting Purchaser to purchase its pro rata share (based on the principal amount of Securities which such Purchaser agreed to purchase hereunder) of the Securities of such defaulting Purchaser or Purchasers for which such arrangements have not been made; but nothing herein shall relieve a defaulting Purchaser from liability for its default.

If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Company as provided in subsection (a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Purchasers to purchase Securities of a defaulting Purchaser or Purchasers, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Purchaser or the Company, except for the expenses to be borne by the Company and the Purchasers as provided in Section 6 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Purchaser from liability for its default.

11.

The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Purchasers, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Purchaser or any affiliate, director, officer or controlling person of any Purchaser, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities.

12.

If this Agreement shall be terminated pursuant to Section 10 hereof, the Company shall not then be under any liability to any Purchaser except as provided in Sections 7 and 9 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Purchasers through you for all expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Purchasers in making preparations for the purchase, sale and delivery of the Securities, but the Company shall then be under no further liability to any Purchaser except as provided in Sections 7 and 9 hereof.

13.

In all dealings hereunder, you shall act on behalf of each of the Purchasers, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Purchaser made or given by you.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Purchasers shall be delivered or sent by mail or facsimile transmission to you as the representatives at 000 Xxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000-0000, Attention: Registration Department; and if to the Company shall be delivered or sent by mail or facsimile transmission to the address of the Company set forth in the Offering Memorandum, Attention: Corporate Secretary; provided, however, that any notice to a Purchaser pursuant to Section 9 hereof shall be delivered or sent by mail or facsimile transmission to such Purchaser at its address set forth in its Purchasers’ Questionnaire, which address will be supplied to the Company by you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Purchasers to properly identify their respective clients.

14.

This Agreement shall be binding upon, and inure solely to the benefit of, the Purchasers, the Company and, to the extent provided in Sections 9 and 11 hereof, the officers and directors of the Company and each person who controls the Company or any Purchaser, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Purchaser shall be deemed a successor or assign by reason merely of such purchase.

15.

The Securities have not been and will not be registered under the Act and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except in accordance with Regulation S under the Act or pursuant to an exemption from the registration requirements of the Act.

Accordingly, each Purchaser agrees that neither it, its affiliates nor any persons acting on its or their behalf has engaged or will engage in any directed selling efforts with respect to the Securities, and it and they have complied and will comply with the offering restrictions requirement of Regulation S. Each Purchaser agrees that, at or prior to confirmation of sale of Securities (other than a sale pursuant to Rule 144A), it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it during the restricted period a confirmation or notice to substantially the following effect:

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933 (the “Securities Act”) and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering and the closing date, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meaning given to them by Regulation S.”

Terms used in this paragraph have the meanings given to them by Regulation S.

Each Purchaser further agrees that it has not entered and will not enter into any contractual arrangement with respect to the distribution or delivery of the Securities, except with its affiliates or with the prior written consent of the Company.

Each Purchaser understands that no action has been taken to permit a public offering in any jurisdiction outside the United States where action would be required for such purpose. Each Purchaser agrees not to cause any advertisement of the Securities to be published in any newspaper or periodical or posted in any public place and not to issue any memorandum relating to the Securities, except in any such case with Xxxxxxx, Xxxxx & Co.’s express written consent and then only at its own risk and expense.
