or supplement thereto), or the Canadian Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the information contained in Schedule 6.

(c)                                  Notice and Procedures.  If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above.  If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred.  In any such proceeding, any Indemnified Person 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 Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person 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 Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them.  It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred.  Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representative, and any such separate firm for the Company, the Guarantors, their respective directors and officers who signed the Registration Statement and any control persons of the Company and the Guarantors shall be designated in writing by the Company.  The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified

30

Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)                                 Contribution.  If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations.  The relative benefits received by the Company and the Guarantors on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities.  The relative fault of the Company and the Guarantors on the one hand and the Underwriters on the other 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 or any Guarantor or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e)                                  Limitation on Liability.  The Company, the Guarantors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above.  The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim.  Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

31

(f)                                   The Company and the Guarantors will, jointly and severally, indemnify and hold harmless the Underwriters against any documentary, stamp, sales, transaction or similar issue tax, including any interest and penalties, on the creation, issue and sale of the Securities and on the execution and delivery of this Agreement.  All payments to be made by the Company or the Guarantors to the Underwriters under this Agreement shall be made without withholding or deduction for or on account of any present or future taxes, duties or governmental charges whatsoever unless the Company or such Guarantor is compelled by law to deduct or withhold such taxes, duties or charges. In that event, the Company and the Guarantors shall pay to the Underwriters such additional amounts as may be necessary in order that the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made, provided that no such additional amounts shall be payable: (i) with respect to taxes imposed by any taxing or other governmental authority by reason of any present or former connection between any of the Underwriters and the relevant taxing jurisdiction, other than any such connection arising solely from such person having executed, delivered or performed its obligations under this Agreement or receiving payments hereunder or the enforcement of rights in respect thereto, (ii) with respect to taxes imposed on fees payable in respect of services rendered in Canada or (iii) to the extent that such taxes would not have been imposed but for the failure of any of the Underwriters to use reasonable efforts to comply with a written notice requesting any certification, identification or other information concerning the nationality, residence, identity or connection with the relevant taxing jurisdiction of such person that it is legally able to provide, if such compliance is required or imposed by law as a precondition to an exemption from, or reduction in, such taxes. If any taxes are collected by deduction or withholding, the Company will provide the Underwriters copies of documentation evidencing the transmittal to the proper authorities of the amount of taxes deducted or withheld within 15 days after payment of such taxes.

(g)                                  Non-Exclusive Remedies.  The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8.                                      Termination.  This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange, the Toronto Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company or any of the Guarantors shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by U.S. or Canadian federal, New York State, Ontario or British Columbia authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States and Canada, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

32

9.                                      Defaulting Underwriter.

(a)                                 If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement.  If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms.  If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Time of Sale Information, the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement, the Time of Sale Information or the Prospectus that effects any such changes.  As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b)                                 If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that 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 Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c)                                  If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that 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 paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters.  Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company or the Guarantors, except that the Company and each of the Guarantors will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d)                                 Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Guarantors or any non-defaulting Underwriter for damages caused by its default.

33

10.                               Payment of Expenses.

(a)                                 Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company and each of the Guarantors jointly and severally agree to pay or cause to be paid all costs and expenses incident to the performance of their respective obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and the grant and perfection of the security interests with respect thereto and any taxes payable in connection therewith; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Time of Sale Information, any Issuer Free Writing Prospectus and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s and the Guarantors’ counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representative may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of U.S. and Canadian counsel for the Underwriters) (subject to a maximum amount not to exceed $30,000); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the U.S. Trustee, the Canadian Trustee, any paying agent and the Collateral Agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority, and the approval of the Securities for book-entry transfer by DTC and CDS; (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors, except that the Company and the Guarantors jointly and severally agree to pay or cause to be paid only 50% of all costs of, and expenses relating to, any aircraft chartered in connection with attending or hosting such presentations; and (x) all filing costs and expenses relating to the perfection of the security interests in the Collateral, as set forth in the Security Documents (including, without limitation, mortgage recording or similar taxes and all costs related to the title insurance and other deliverables in respect of the Mortgages) and the reasonable fees and expenses of counsel to the Underwriters in connection with the perfection of security interests (including Cahill Gordon & Reindel LLP and Holland & Hart LLP, special mining counsel to the Underwriters).

(b)                                 If (i) this Agreement is terminated pursuant to Section 8, (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement, the Company and each of the Guarantors, jointly and severally, agrees to reimburse the Underwriters for all out-of-pocket costs and expenses (including the fees and expenses of their counsel and the costs of, and expenses relating to, any aircraft chartered as referred to in Section 10(a)(ix)) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

11.                               Persons Entitled to Benefit of Agreement.  This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates, officers and directors of each Underwriter referred to in Section 7 hereof.  Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or

34

in respect of this Agreement or any provision contained herein.  No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

12.                               Survival.  The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Guarantors and the Underwriters contained in this Agreement or made by or on behalf of the Company, the Guarantors or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Guarantors or the Underwriters.

13.                               Certain Defined Terms.  For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

14.                               Compliance with USA Patriot Act.  In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters 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 Underwriters to properly identify their respective clients.

15.                               Miscellaneous.

(a)                                 Authority of the Representative.  Any action by the Underwriters hereunder may be taken by Deutsche Bank Securities Inc. on behalf of the Underwriters, and any such action taken by Deutsche Bank Securities Inc. shall be binding upon the Underwriters

(b)                                 Notices.  All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted and confirmed by any standard form of telecommunication.  Notices to the Underwriters shall be given to the Representative c/o Deutsche Bank Securities Inc., 60 Wall Street, New York, New York 10005, Attention: Leveraged Debt Capital Markets, 2nd Floor (fax: (212) 797-4877), with a copy to the attention of the General Counsel, 36th Floor (fax: (212) 797-4561).  Notices to the Company and the Guarantors shall be given to them at 26 West Dry Creek Circle, Suite 810, Littleton, CO 80120 (fax: 303-762-3511); Attention: Wendy Cassity.

(c)                                  Submission to Jurisdiction, etc.  The Company and each Guarantor irrevocably and unconditionally submit to the exclusive jurisdiction of the state and federal courts sitting in the County and City of New York over any suit, action or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.  Service of any process, summons, notice or document by registered mail addressed to the Company or any Guarantor at the address above in Section 15(b) shall be effective service of process against the Company for any suit, action or proceeding brought in any such court. The Company and each Guarantor irrevocably and unconditionally waives any objection to the laying of venue of any such suit, action or proceeding

35

brought in any such court and any claim that any such suit, action or proceeding has been brought in an inconvenient forum.  A final judgment in any such suit, action or proceeding brought in any such court shall be conclusive and binding upon the Company and each Guarantor and may be enforced in any other courts to whose jurisdiction the Company is or may be subject, by suit upon judgment.  The Company and each Guarantor further agrees that nothing herein shall affect any Underwriter’s right to effect service of process in any other manner permitted by law or bring a suit action or proceeding (including a proceeding for enforcement of a judgment) in any other court or jurisdiction in accordance with applicable law.

(d)                                 Waiver of Jury Trial.  Each of the parties hereto hereby waives any right to trial by jury in any suit or proceeding arising out of or relating to this Agreement.

(e)                                  Judgment Currency.  The obligation of the Company and each Canadian Guarantor in respect of any sum due to any Underwriter under this Agreement shall, notwithstanding any judgment in a currency other than U.S. dollars or any other applicable currency (the “Judgment Currency”), not be discharged until the first business day, following receipt by such Underwriter of any sum adjudged to be so due in the Judgment Currency, on which (and only to the extent that) such Underwriter may in accordance with normal banking procedures purchase U.S. dollars or any other applicable currency with the Judgment Currency; if the U.S. dollars or other applicable currency so purchased are less than the sum originally due to such Underwriter hereunder, the Company and each Canadian Guarantor agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter against such loss.  If the U.S. dollars or other applicable currency so purchased are greater than the sum originally due to such Underwriter hereunder, such Underwriter agrees to pay to the Company or the Canadian Guarantor, as the case may be, an amount equal to the excess of the U.S. dollars or other applicable currency so purchased over the sum originally due to such Underwriter hereunder.

(f)                                   Waiver of Immunity.  To the extent that each of the Company and the Guarantors, or any of their respective properties, assets or revenues may have or may hereafter become entitled to, or have attributed to each of the Company and the Guarantors, any right of immunity, on the grounds of sovereignty or otherwise, from any legal action, suit or proceeding, from the giving of any relief in any such legal action, suit or proceeding, from setoff or counterclaim, from the jurisdiction of any Canadian, New York state or U.S. federal court, from service of process, from attachment upon or prior to judgment, from attachment in aid of execution of judgment, or from execution of judgment, or other legal process or proceeding for the giving of any relief or for the enforcement of any judgment, in any such court in which proceedings may at any time be commenced, with respect to the obligations and liabilities of each of the Company and the Guarantors or any other matter under or arising out of or in connection with this Agreement, each of the Company and the Guarantors hereby irrevocably and unconditionally waives or will waive such right to the extent permitted by applicable law, and agree not to plead or claim, any such immunity and consent to such relief and enforcement.
