Neither the Company nor Parent has taken, directly or indirectly, any action designed to or that would constitute or that is intended to or that might reasonably be expected to cause or result in, under the Securities Laws or otherwise, stabilization, maintenance or manipulation of the price of any security of the Company or Parent to facilitate the sale or resale of the Securities.

(gg) Certain Environmental Matters. Except as set forth in or contemplated in the Disclosure Package and the USCA Final Prospectuses (exclusive of any supplement thereto), Parent and its subsidiaries are (i) in compliance with Environmental Laws, (ii) have received and are in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) have not received notice of any actual or potential liability for the investigation or remediation of any disposal or release of hazardous or toxic substances or wastes, pollutants or contaminants, except where such non-compliance with Environmental Laws, failure to receive required permits, licenses or other approvals, or liability would not, individually or in the aggregate, have a material adverse effect on the

11

condition (financial or otherwise), prospects, earnings, business or properties of Parent and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business. Except as set forth in or contemplated in the Disclosure Package and the USCA Final Prospectuses (exclusive of any supplement thereto), neither Parent nor any of the subsidiaries has been named as a “potentially responsible party” with respect to any material environmental issue under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended, or under any similar Canadian legislation.

In the ordinary course of its business, Parent periodically reviews the effect of Environmental Laws on the business, operations and properties of Parent and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties); Parent also conducts pre-acquisition investigations of new railroad properties to identify potential violations of Environmental Laws, trains management personnel in the recognition of and proper response to incidents of noncompliance with Environmental Laws and establishes procedures for communicating such incidents to Parent’s headquarters. On the basis of such review, except as set forth in or contemplated in the Disclosure Package or USCA Final Prospectuses has concluded that such associated costs and liabilities would not, singly or in the aggregate, have a material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of Parent and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business.

(hh) Compliance with ERISA. Each of Parent and its subsidiaries has fulfilled its obligations, if any, under the minimum funding standards of Section 302 of the United States Employee Retirement Income Security Act of 1974 (“ERISA”) and the regulations and published interpretations thereunder with respect to each “plan” (as defined in Section 3(3) of ERISA and such regulations and published interpretations) in which employees of Parent and its subsidiaries are eligible to participate and each such plan is in compliance with the presently applicable provisions of ERISA and such regulations and published interpretations. Parent and its subsidiaries have not incurred any unpaid liability to the Pension Benefit Guaranty Corporation (other than for the payment of premiums in the ordinary course) or to any such plan under Title IV of ERISA, in each case, except as would not, individually or in the aggregate, have a material adverse effect on the condition (financial or otherwise), prospectus, earnings, business or properties of Parent and its subsidiaries, taken as a whole.

(ii) Subsidiaries. The subsidiaries listed on Schedule 2 attached hereto are the only Significant Subsidiaries (as such term is defined in Rule 1-02 of Regulation S-X under the Securities Act) of Parent and there are no other subsidiaries material to the condition (financial or otherwise), prospects, earnings, business or properties of Parent and its subsidiaries, taken as a whole.

The Guarantee has been

12

(kk) The Indenture. The Indenture has been duly authorized by the Company and Parent, and the Base Indenture has been duly qualified under the Trust Indenture Act, and the Indenture constitutes a valid and legally binding instrument of the Company and Parent, and enforceable against the Company and Parent in accordance with its terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, fraudulent conveyances or transfer, moratorium or similar laws affecting creditors’ rights generally and subject to general principles of equity (regardless of whether enforceability is considered in a proceeding in equity or at law); no registration, filing or recording of the Indenture under the laws of Canada or any province thereof is necessary in order to preserve or protect the validity or enforceability of the Indenture or the Securities issued thereunder; and the Indenture conforms, and the Securities will conform in all material respects to the descriptions thereof contained in the Disclosure Package and the USCA Final Prospectuses with respect to such Securities.

Except as set forth in the Disclosure Package or the USCA Final Prospectuses (i) there are no rights of third parties to any such Intellectual Property, except for any rights that may exist that would not, individually or in the aggregate, cause a material adverse effect on the condition (financial or otherwise), prospects, earnings, business or properties of Parent and its subsidiaries, taken as a whole; (ii) there is no material infringement by third parties of any such Intellectual Property; (iii) there is no pending or, to the knowledge of the Company or Parent, threatened action, suit, proceeding or claim by others challenging the Company’s or Parent’s rights in or to any such Intellectual

The Company and Parent acknowledge that (i) the statements set forth in the second to last paragraph of the cover page regarding delivery of the Securities and, under the heading “Underwriting,” (ii) the list of Underwriters and their respective participation in the sale of the Securities, (iii) the sentences related to concessions and reallowances, (iv) the sentence related to certain underwriters not being U.S. registered broker-dealers (“Certain of the Underwriters may not be U.S. registered broker-dealers and accordingly will not effect any sales within the United States except in compliance with applicable U.S. laws and regulations, including the rules of the Financial Industry Regulatory Authority.”) and (v) the paragraph related to stabilization, syndicate covering transactions and penalty bids in the Preliminary Prospectus and the USCA Final Prospectuses constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Registration Statement, the USCA Final Prospectuses or the Disclosure Package (together, “Underwriter Information”).

(c) As used in this Section 7, (i) “Indemnified Party” means a person seeking indemnity or making a claim for indemnification under Section 7(a) or (b), as applicable, and “Indemnified Parties” means each of them, and (ii) “Indemnifying Party” means the applicable person or persons against whom such indemnity may be sought.

In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 7(a) or (b) hereof is unavailable, in whole or in part, for any reason to an Indemnified Party in respect of any liabilities, claims, demands, losses, costs, damages and expenses referred to therein, then each Indemnifying Party shall contribute to the aggregate amount paid or payable (or, if such indemnity is unavailable only in respect of a portion of the amount so paid or payable, such portion of the amount so paid or payable) by such Indemnified Party or Indemnified Parties as a result of such liabilities, claims, demands, losses, costs, damages and expenses:

(i) in such proportion as is appropriate to reflect as between the Company, Parent and the Underwriters, the relative benefits received by the Company and Parent on the one hand and by the Underwriters on the other hand from the offering of the Securities; or

22

(ii) if the allocation provided by clause (c)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (c)(i) above but also the relative fault of the Company and Parent on the one hand and the Underwriters on the other hand, as well as any other relevant equitable considerations; provided that no Underwriter shall in any event be liable to contribute, in the aggregate, any amount in excess of the amount of the total underwriting discounts and commissions received by the Underwriter with respect to the offering of the Securities.

The relative benefits received by the Company and Parent on the one hand and the Underwriters on the other shall be deemed to be in the same ratio as the total net proceeds from the distribution of the Securities (before deducting expenses) received by the Company and Parent is to the total underwriting discounts and commissions received by the Underwriters in connection with the sale of the Securities, based on the purchase price of the Securities.

The relative fault of the Company and Parent on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the matters or things referred to in Section 7(a) or (b) hereof which resulted in such liabilities, claims, demands, losses, costs, damages and expenses relate to information supplied by or steps or actions taken or done or not taken or done (including any non-compliance, breach or default) by or on behalf of the Company or Parent or by the Underwriters and the relative intent, knowledge, access to information and opportunity to correct or prevent such statement, omission or misrepresentation, or other matter or thing referred to in Section 7(a) or (b) hereof.

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 7(c) were determined by any method of allocation which does not take into account the equitable considerations referred to above in this Section 7(c). Notwithstanding the provisions of this Section 7(c), 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.

(d) If any matter or thing contemplated by this Section 7 shall be asserted against any Indemnified Party, the Indemnified Party concerned shall promptly notify the Indemnifying Party and the other parties to this Agreement of the nature of such claim (provided that any failure to so notify the Indemnifying Party or any such other party promptly shall relieve the Indemnifying Party of liability under this Section 7 only to the extent that such failure prejudices the Indemnifying Party’s to defend such claim), and the Indemnifying Party shall, subject as hereinafter provided, be entitled (but not required) to assume the defense of any suit or proceeding (including any governmental or regulatory investigation or proceeding) brought to enforce such claim. Any such defense shall be through legal counsel acceptable to the Indemnified Party (whose acceptance shall not be unreasonably withheld) and no admission of liability or settlement shall be made by the Indemnifying Party or any other Indemnified Party in respect of any Indemnified Party without, in each case, the prior written consent of the Indemnified Party. An Indemnified Party shall have the right to employ separate counsel in any such suit and participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of the Indemnified Party unless: (i) the Indemnifying Party fails to assume the defense of such suit on behalf of the Indemnified Party within a reasonable period of time; or (ii) the employment of such counsel has been authorized in writing by the Indemnifying Party; or (iii) the named parties to any such suit or proceeding include the Indemnified Party as well as the Indemnifying Party and the Indemnified Party shall have received a written opinion from counsel that there may be one or more legal

23

defenses available to the Indemnified Party which are different from or in addition to those available to the Indemnifying Party and that representation of the Indemnified Party by counsel to the Indemnifying Party is inadvisable as a result of the potential or actual conflicts of interest of those represented (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party, the Indemnifying Party shall not have the right to assume the defense of such suit or proceeding on behalf of the Indemnified Party and shall be liable to pay the reasonable fees and expenses of counsel for the Indemnified Party), it being understood, however, that the Indemnifying Party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate law firm for all such Indemnified Parties (other than local counsel).

It is the intention of the parties to constitute each of the Underwriters, the Company and Parent as trustees for their respective affiliates involved in the distribution of the Securities and the respective directors, officers, shareholders, agents and employees, and each person who controls any Underwriter, the Company or Parent, respectively, of the covenants of the applicable Indemnifying Party under Section 7(a) and 7(b) hereof, as applicable, with respect to their respective directors, officers, shareholders, affiliates involved in the distribution of the Securities offered hereby, agents and employees, and each person who controls any Underwriter, and the Underwriters, the Company and Parent agree to accept such trust and to hold and enforce such covenants on behalf of such persons.

(e) The Company and Parent agree that in case any legal proceedings or investigation shall be brought against or initiated against them by any governmental commission, regulatory authority, exchange, court or other authority and any of the Underwriters or their representatives or related Indemnified Parties shall be required to testify or respond to procedures designed to discover information regarding, in connection with or relating to the performance of professional services rendered to the Company or Parent by one or more of the Underwriters or their affiliates involved in the distribution of the Securities in connection with the sale of the Securities offered hereby, the Company and Parent agree to pay the Underwriter or their affiliates involved in the distribution of the Securities offered hereby the reasonable costs (including an amount to reimburse the Underwriter for the time spent by the personnel in connection therewith on a per diem basis and out-of-pocket expenses) in connection therewith.

(f) The rights provided in this Section 7 shall be in addition to and not in derogation of any other right which the Underwriters, the Company or Parent may have by statute or otherwise at law.

8. Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.

9. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company and Parent prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in common shares of Parent shall have been suspended by the Commission, the Alberta Securities Commission, the New York Stock Exchange or the Toronto Stock Exchange, (ii) trading in securities generally on the New York Stock Exchange or the Toronto Stock Exchange or the Nasdaq National Market shall have been suspended or limited or minimum prices shall have been established on any of such exchanges, (iii) a banking moratorium shall have been declared either by authorities in the United States, Canada or New York, (iv) a change or development

24

involving a prospective change in Canadian taxation affecting the Securities or the transfer thereof or the imposition of exchange controls by the United States or Canada, or (v) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States or Canada of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Disclosure Package (exclusive of any supplement thereto) and the USCA Final Prospectuses (exclusive of any supplement thereto).

10. Defaulting Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule 1 hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule 1 hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Company and Parent. In the event of a default by any Underwriter as set forth in this Section 10, the Closing Date shall be postponed for such period, not exceeding five business days, as the Representatives shall determine in order that the required changes in the Registration Statement and the USCA Final Prospectuses or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company, Parent and any nondefaulting Underwriter for damages occasioned by its default hereunder.

11. Payment of Expenses. The Company and Parent, jointly and severally, agree to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), each Issuer Free Writing Prospectus and the USCA Final Prospectuses, and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Issuer Free Writing Prospectus, the Preliminary Prospectus, the USCA Final Prospectuses, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities, including any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification) and the preparation and printing of any blue sky memorandum; (v) the transportation and other expenses in connection with presentations to prospective purchasers of the Securities; (vi) the fees and expenses of the Company and Parent’s accountants and the fees and expenses of counsel (including local and special counsel) for the Company and Parent; (vii) 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; (viii) any fees charged by securities rating services for rating the Securities; and (ix) all other costs and expenses of the Company, Parent and the Representatives incident to the performance by the Company and Parent of their obligations hereunder.

25

If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 9(ii) hereof or because of any refusal, inability or failure on the part of the Company or Parent to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Company and Parent will reimburse the Underwriters severally through the Representatives on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities; provided however, that solely for the purpose of this Section 11, the condition set forth in Section 6(e)(ii) shall not include a change, or any development involving a prospective change affecting the condition (financial or otherwise), earnings, business or properties of the North American railway companies taken as a whole and which materially affects substantially all such companies.

12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, Parent and the Underwriters contained in this Agreement or made by or on behalf of the Company, Parent 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, Parent or the Underwriters.

13. 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 and Parent, 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.

14. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Underwriters, will be mailed, delivered or telefaxed to the Representatives at Barclays Capital Inc. at (646) 834-8133 and confirmed to it at 745 Seventh Avenue, New York, New York 10019, Attention: Syndicate Registration; Citigroup Global Markets Inc. at (646) 291-1469 and confirmed to it at 388 Greenwich Street, New York, New York 10013, Attention: General Counsel; HSBC Securities (USA) Inc. at (212) 525-0238 and confirmed to it at 452 Fifth Avenue, New York, NY 10018, Attention: Transaction Management Group; Morgan Stanley & Co.

15. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 7 hereof, and no other person will have any right or obligation hereunder.

16. Submission to Jurisdiction; Agent for Service; Waiver of Immunities. Each of the Company and Parent irrevocably (i) agrees that any legal suit, action or proceeding against the Company or Parent brought by any Underwriter or by any person who controls any Underwriter arising out of or based upon this Agreement or the transactions contemplated thereby may be instituted in any New York Court, (ii) waives, to the fullest extent it may effectively do so, any objection which it may now or hereafter have to the laying of venue of any such proceeding and (iii) submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The Company and Parent have appointed CT Corporation System, New York, New York, as their authorized agent (the “Authorized Agent”) upon whom process may be served, at 28 Liberty Street, 42^nd Floor, New York, New York, 10005, USA, in any such action

26

arising out of or based on this Agreement or the transactions contemplated hereby which may be instituted in any New York Court by any Underwriter or by any person who controls any Underwriter, expressly consent to the jurisdiction of any such court in respect of any such action, and waive any other requirements of or objections to personal jurisdiction with respect thereto. Such appointment shall be irrevocable. The Company and Parent represent and warrant that the Authorized Agent has agreed to act as such agent for service of process and agree to take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment in full force and effect as aforesaid. Service of process upon the Authorized Agent and written notice of such service to the Company or Parent shall be deemed, in every respect, effective service of process upon the Company or Parent, as the case may be.

To the extent that either of the Company or Parent has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service of notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, it hereby irrevocably waives such immunity in respect of its obligations under the above-referenced documents, to the extent permitted by law.

The provisions of this Section 16 shall survive any termination of this Agreement, in whole or in part.

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

18. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

19. Counterparts. The Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.

20. Headings. The section headings used herein are for convenience only and shall not affect the construction hereof.

21. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Securities, represents the entire agreement between the Company and Parent on the one hand and the Underwriters on the other hand with respect to the preparation of any preliminary prospectus, the Disclosure Package, the USCA Final Prospectuses, the conduct of the offering, and the purchase and sale of the Securities.

27

The Company and Parent acknowledge that in connection with the offering of the Securities: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Company, Parent or any other person, (ii) the Underwriters owe the Company and Parent only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any, and (iii) the Underwriters may have interests that differ from those of the Company and Parent. The Company and Parent waive to the full extent permitted by applicable law any claims they may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Securities.

22. Recognition of the U.S. Special Resolution Regimes. Notwithstanding any other provisions herein, (i) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States. (ii) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.
