4. Agreements. The Company agrees with the Representatives and the several Underwriters that:

(a) Prior to the termination of the Offering, the Company will not file any amendment or supplement to the Registration Statement or the Basic Prospectus or U.S. Basic Prospectus (including the Canadian Final Prospectus, the U.S. Final Prospectus or any Preliminary Final Prospectus) unless the Company has furnished a copy to the Representatives for their review prior to filing and will not file any such proposed amendment or supplement to which the Representatives reasonably object unless filing is immediately required by law without right of appeal.

period will advise the Representatives, promptly after it receives notice thereof, of the time when any amendment to the Canadian Final Prospectus has been filed or receipted, when any amendment to the Registration Statement has been filed or becomes effective or any supplement to the Basic Prospectus or U.S. Basic Prospectus or any amended Canadian Final Prospectus or U.S. Final Prospectus has been filed with the Reviewing Authority or the Commission, of the issuance by the Reviewing Authority or the Commission of any stop order or of any order preventing or suspending the use of any prospectus relating to the Securities, of the suspension of the qualification of such Securities for offering or sale in any jurisdiction, of the initiation or threatening, to the knowledge of the Company, of any proceeding for any such purpose, or of any request by the Reviewing Authority or the Commission for the amending or supplementing of the Registration Statement, the Canadian Final Prospectus or the U.S. Final Prospectus or for additional information relating to the Securities; and the Company will use its commercially reasonable best efforts to prevent the issuance of any such stop order or any such order preventing or suspending the use of any prospectus relating to the Securities or the suspension of any such qualification and, in the event of the issuance of any such stop order or of any such order preventing or suspending the use of any prospectus relating to the Securities or suspending any such qualification, to use its commercially reasonable best efforts to obtain the withdrawal of such order as soon as possible;

(b) Notwithstanding the provisions of paragraph 4(a) above, if, at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Canadian Final Prospectus or the U.S. Final Prospectus, each as then supplemented, or the Disclosure Package, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Canadian Final Prospectus, the U.S. Final Prospectus or the Disclosure Package to comply with Alberta Securities Law, the Act or the Exchange Act, the Company will promptly (i) notify the Representatives of such event, (ii) prepare and file with the Reviewing Authority and the Commission an amendment or supplement which will correct such statement or omission or effect such compliance and (iii) supply any supplemented Canadian Final Prospectus and U.S. Final Prospectus or Disclosure Package to the Representatives in such quantities as they may reasonably request;

(c) As soon as practicable, the Company will make generally available to its security holders an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158;

(d) The Company will furnish to the Representatives and counsel for the Underwriters, without charge, copies of the Registration Statement (including exhibits thereto) and to the Representatives for delivery to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Final Prospectus, Issuer Free Writing Prospectus and U.S. Final Prospectus and any supplement thereto as the Representatives may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the Offering;

(e) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may designate upon consultation with the Company and will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of the FINRA in connection with its review of the Offering; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject;

(f) The Company agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to

7. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed, the Basic Prospectus, any Preliminary Final Prospectus, the Canadian Final Prospectus, the U.S. Final Prospectus or any Issuer Free Writing Prospectus, or in all cases any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company will 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 any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, each of its directors, its officers, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have. The Company acknowledges that the statements set forth in the second to last paragraph of the cover page regarding stabilization and concessions and the last paragraph of the cover page regarding delivery of the Securities and, under the heading “Underwriting”, (i) the names listed in the table included in the first paragraph of the text, (ii) the fifth paragraph of text concerning concessions, (iii) the eighth paragraph of text concerning confirmation of sales to any account over which the Underwriters exercise discretionary authority, (iv) the third sentence in the ninth paragraph of text concerning market making by the Underwriters, and (v) the tenth, eleventh,

twelfth, thirteenth and fourteenth paragraphs of text concerning short sales, stabilizing transactions and penalty bids, in any Preliminary Final Prospectus, Canadian Final Prospectus and U.S. Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Final Prospectus, the Registration Statement, the Disclosure Package, the U.S. Final Prospectus or Canadian Final Prospectus.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively, “Losses”) to which the Company and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall any Underwriter (except as may be provided in any agreement among Underwriters relating to the Offering) be responsible for any amount in excess of the total price at which the Securities underwritten and distributed to the public by such Underwriter was offered to the public. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Underwriters severally shall contribute 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 of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the Offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Canadian Final Prospectus and the U.S. Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of

allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls an Underwriter within the meaning of the Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of the Act, each officer of the Company and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

8. Default by an 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, then the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all of the unsold Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then the non-defaulting 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 II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the non-defaulting 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 II hereto, the non-defaulting Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such non-defaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any non-defaulting Underwriter or the Company. In the event of a default by any Underwriter as set forth in this Section 8, the Closing Date shall be postponed for such period, not exceeding seven Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement, the Canadian Final Prospectus and the U.S. Final Prospectus 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 and any non-defaulting Underwriter for damages occasioned by its default hereunder.

9. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time, (i) trading in securities generally on the New York Stock Exchange or the Toronto Stock Exchange or the Nasdaq Global Market shall have been suspended or limited or minimum prices shall have been established on any of such Exchanges, (ii) a banking moratorium shall have been declared either by authorities in the United States, Canada or New York state, (iii) there shall have occurred a change or development 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 (iv) there shall have occurred any outbreak or escalation of hostilities, except as existing with similar severity on the date hereof involving Canada or the United States, declaration by the United States or Canada of a national emergency or war, or other calamity or crisis, except as existing with similar severity on the date hereof 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 Canadian Final Prospectus, the Disclosure Package and the U.S. Final Prospectus.

10. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 6, 7 and 13 hereof shall survive the termination or cancellation of this Agreement.

12. 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.

13. Submission to Jurisdiction; Agent for Service; Waiver of Immunities. The Company irrevocably (i) agrees that any legal suit, action or proceeding against the Company 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 in any court of the State of New York or the courts of the United States of America located in the City of New York and (iii) submits to the non-exclusive jurisdiction of such courts in any such suit, action or proceeding. The Company has appointed TransCanada PipeLine USA Ltd. as its authorized agent (the “Authorized Agent”) upon whom process may be served in any such action arising out of or based on this Agreement or the transactions contemplated thereby which may be instituted in any New York Court by any Underwriter or by any person who controls any Underwriter, expressly consents to the jurisdiction of any such court in respect of any such action, and waives any other requirements of or objections to personal jurisdiction with respect thereto. Such appointment shall be irrevocable. The Company represents and warrants that the Authorized Agent has agreed to act as such agent for service of process and agrees 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 shall be deemed, in every respect, effective service of process upon the Company.

To the extent that the Company 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 13 shall survive any termination of this Agreement, in whole or in part.

14. Judgment Currency. The obligation of the Company 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 (as converted into U.S. dollars at the rate of exchange announced by the Bank of Canada on the day on which the final judgment is entered) to such Underwriter hereunder, the Company agrees, 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 an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter hereunder.

15. No Advisory or Fiduciary Responsibility. The Company acknowledges and agrees that (i) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company with respect to the Offering or the process leading thereto (irrespective of whether such Underwriter has advised or is

currently advising the Company on other matters) or any other obligation to the Company except the obligations expressly set forth in this Agreement and (iv) the Company has consulted its own legal and financial advisors to the extent it deemed appropriate. The Company agrees that it will not claim that any Underwriter has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

ANNEX I

Opinion of Xxxxx Xxxxx LLP

United States Counsel to the Company

(i) Each of TransCanada PipeLine USA Ltd., TransCanada American Investments Ltd., TransCanada Oil Pipelines Inc., TransCanada Keystone Pipeline, LLC and TransCanada Keystone Pipeline, LP is a corporation, a limited liability company or a limited partnership, as the case may be, in good standing under the laws of the respective jurisdiction of its incorporation or organization.

(ii) Assuming the compliance of the Canadian Final Prospectus, including the documents incorporated by reference therein, with the requirements of the securities laws and regulations of the Province of Alberta and other requirements of Canadian law, the Registration Statement and the U.S. Final Prospectus (other than the financial statements, including schedules, and other financial and statistical information contained therein or omitted therefrom, and the Form T-1, as to which such counsel need express no opinion) appear on their face to be appropriately responsive as to form in all material respects with the applicable requirements of the Act and the rules and regulations thereunder; the Form F-X, as of its date, appears on its face to be appropriately responsive in all material respects to the requirements of the Act.

(iii) No consent, approval, authorization or order of, or filing, registration or qualification with, any Governmental Authority, which has not been obtained, taken or made (other than as required by any state securities laws, as to which such counsel expresses no opinion) is required on the part of the Company under any Applicable Law for the issuance or sale of the Securities or the performance by the Company of its obligations under this Agreement and the Indenture. For purposes of this opinion, the term “Governmental Authority” means any executive, legislative, judicial, administrative or regulatory body of the State of New York or the United States of America. For purposes of this opinion, the term “Applicable Law” means those laws, rules and regulations of the United States of America and the State of New York, in each case which in our experience are normally applicable to the transactions of the type contemplated by this Agreement.

(iv) Assuming that the Indenture has been duly authorized by the Company, the Indenture (to the extent execution and delivery are governed by the laws of New York) has been duly executed and delivered by the Company and constitutes a valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except that the enforceability of the Indenture may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance 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), and the Indenture conforms in all material respects to the description thereof contained in each of the U.S. Final Prospectus and the Disclosure Package under the caption “Description of Debt Securities” and under the caption “Description of the Notes”. The Indenture has been duly qualified under the Trust Indenture Act.

(v) Assuming that the Securities have been duly authorized by the Company, the Securities (to the extent execution, authentication and delivery are governed by the laws of New York) have been duly executed and authenticated in accordance with the provisions of the Indenture and delivered by the Company against payment as provided in this Agreement, the Securities will constitute valid and legally binding obligations of the Company entitled to the benefits of the Indenture and will be enforceable against the Company in accordance with their terms, except that the enforceability of the Securities may be subject to bankruptcy, insolvency, reorganization, fraudulent conveyance 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). The Securities, when issued and delivered, will conform in all material respects to the description contained in each of the U.S. Final Prospectus and the Disclosure Package, under the caption “Description of the Notes” and “Description of Debt Securities” and are in a form contemplated in the Indenture.

I-1

(vi) Assuming that this Agreement has been duly authorized by the Company, this Agreement (to the extent execution and delivery are governed by the laws of New York) has been duly executed and delivered by the Company.

(vii) The Company is not and, after giving effect to the offering and the sale of the Securities and the application of their proceeds as described in each of the U.S. Final Prospectus and the Disclosure Package under the heading “Use of Proceeds,” will not be required to be registered as an investment company under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission promulgated thereunder.

(viii) The statements in each of the U.S. Final Prospectus and the Disclosure Package under the caption “Certain Income Tax Considerations — Certain U.S. Federal Income Tax Considerations,” to the extent that they constitute summaries of United States federal statutes, rules and regulations, or portions thereof, are accurate in all material respects.

(ix) Neither the execution and delivery of this Agreement and the Indenture, nor the issue and sale of the Securities, nor the consummation of any other of the transactions herein contemplated nor the fulfillment of the terms hereof will conflict with, result in a breach or violation of or imposition of any lien, charge or encumbrance upon any property or assets of the Company or its subsidiaries pursuant to (i) the terms of such material agreements as are set out in Schedule A hereto or (ii) any United States federal or New York State statute, law, rule, or regulation known to such counsel to be applicable to the Offering, excluding the Company’s and any subsidiary’s specially regulated activities (as to which such counsel need express no opinion) or, to the knowledge of such counsel, any judgment, order or decree applicable to the Company or its subsidiaries of any United States federal or New York State court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or its subsidiaries or any of its or their properties in the United States, except, in the case of (i) or (ii), such conflicts, breaches, violations, liens, charges and encumbrances that, individually or in the aggregate, would not reasonably be expected to have a material adverse effect on the condition (financial or otherwise), earnings, business or properties of the Company and its subsidiaries, taken as a whole.

Such counsel will state that they have been advised by the Commission that the Registration Statement has become effective under the Act. Such counsel will further state that, to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened.

Such counsel will state that they have participated in the preparation of the Registration Statement, the Disclosure Package and the U.S. Final Prospectus and in conferences with officers and other representatives of the Company, representatives of the independent chartered accountants for the Company, the Underwriters and representatives of the Underwriters at which the contents of the Registration Statement, the Disclosure Package, the U.S. Final Prospectus and related matters were discussed. Given the limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process, such counsel may state that they have not verified, and are not passing upon and do not assume responsibility for, the accuracy, completeness or fairness of the statements contained in any of them (other than as explicitly stated in paragraph (viii) above), and have made no independent check or verification thereof (other than as explicitly stated in paragraphs (iv) and (v) above). Subject to the foregoing and in the course of such participation (and relying as to materiality as to factual matters to the extent such counsel deems reasonable on officers, employees and other representatives of the Company), no facts came to such counsel’s attention that caused them to believe that (a) the Registration Statement, at its effective date and on the

I-2

date of this Agreement, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (b) the U.S. Final Prospectus, as of its date and as of the Closing Date, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (c) the Disclosure Package as of the Initial Sale Time and as of the Closing Date, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. In each case, counsel need not express any belief as to (i) financial statements, financial statement schedules and other financial and statistical information or data included or incorporated by reference in or omitted from the Registration Statement, the Disclosure Package and the U.S. Final Prospectus, (ii) the Form T-1 or (iii) discussions of the regulation of the Company’s business under the federal and provincial laws of Canada in documents filed with the Reviewing Authority or filed with the Commission and incorporated by reference in the Registration Statement, the Disclosure Package and the U.S. Final Prospectus. In connection with the foregoing, such counsel may state that it is the understanding of the addressees of such opinion that such counsel does not act as United States regulatory counsel of the Company and does not hold itself out as an expert on the regulation of the generation, transportation, distribution or delivery of natural gas, oil, electricity or other specially regulated commodities or services, including pipelines, transmission lines, storage facilities and related facilities and equipment, or the import or export of such commodities or services.

In rendering such opinion, such counsel may (A) exclude from such opinions the effect or applicability of any United States or Canadian federal, state and local laws, rules or regulations relating to the regulation of the generation, transportation, distribution or delivery of natural gas, oil, electricity or other specially regulated commodities or services, including pipelines, transmission lines, storage facilities and related facilities and equipment, or the import or export of such commodities or services, (B) rely as to matters involving the application of laws of any jurisdiction other than the State of New York or the Federal laws of the United States, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Underwriters and (C) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials.

ANNEX IIa

Opinion of Blake, Xxxxxxx & Xxxxxxx LLP

(ii) each of NOVA Gas Transmission Ltd., 701671 Alberta Ltd. and TransCanada Energy Ltd.

(iv) the Securities have been authorized by the Company and, assuming that the Securities have been authenticated by the Trustee in the manner described in the Indenture and as required under New York law, the Securities have been, to the extent issuance, execution and delivery are matters governed by Applicable Law, issued, executed and delivered by the Company; the Securities conform in all material respects to the description thereof in each of the Canadian Final Prospectus and the Canadian Disclosure Package;

(vii) no consent, approval or authorization or order of or registration, qualification, recording or filing with any governmental body or agency in Canada is required on the part of the Company pursuant to Applicable Law for the performance by the Company of its obligations under the Agreement, the Indenture or the Securities except such as may be required under the securities laws, rules and regulations applicable in the Province of Alberta as interpreted and applied by the Reviewing Authority or such as has been obtained under the CBCA;

(viii) the statements in each of the Canadian Final Prospectus and the Canadian Disclosure Package under the captions “Description of Debt Securities” and “Description of the Notes” insofar as such

IIa-1

statements constitute summaries of the Canadian legal matters, agreements, documents or proceedings referred to therein, fairly summarize the matters referred to therein, subject to specific limitations and qualifications stated or referred to therein and applicable thereto;

(ix) each document incorporated by reference in the Canadian Final Prospectus (other than the financial statements, including schedules, and other financial or statistical data included therein or omitted therefrom, as to which such counsel need express no opinion), when such document was filed with the Reviewing Authority, appeared on its face to be appropriately responsive as to form in all material respects with the requirements of the securities laws, rules and regulations of the Province of Alberta as interpreted and applied by the Reviewing Authority;

(x) a receipt has been obtained in respect of the Basic Prospectus from the Reviewing Authority, the Canadian Final Prospectus has been filed with the Reviewing Authority in the manner and within the time period required by the Shelf Procedures and all necessary documents have been filed, all necessary proceedings have been taken and all necessary authorizations, approvals, permits, consents and orders have been obtained under the securities laws of the Province of Alberta, and no other authorization, approval, permit, consent, license or order of any government, government instrumentality or court under Applicable Law is required, for the issuance, sale and delivery of the Securities through the Underwriters in connection with a public offering thereof in the United States, and, to the knowledge of such counsel, no order having the effect of ceasing or suspending the distribution of the Securities has been issued by the Reviewing Authority and no proceedings for that purpose have been instituted or are pending or contemplated;

(xi) the Basic Prospectus, at the time a final receipt was issued therefor, and the Canadian Final Prospectus, as of the date of its filing with the Reviewing Authority (other than the financial statements, financial schedules and other financial or statistical data included in the foregoing documents, as to which such counsel need express no opinion) complied or comply as to form in all material respects with the requirements of the Shelf Procedures;

(xii) there are no reports or other information that in accordance with the requirements of the Reviewing Authority must be made publicly available in connection with the offering of the Securities that have not been made publicly available on SEDAR as required under Applicable Law;

(xiii) any final and conclusive judgment in personam against the Company in respect of the Agreement, the Indenture or the Securities or any agreement or instrument entered into in connection therewith by a court of the State of New York or of the United States located in the State of New York (a “New York Court”), which is not impeachable as void or voidable under the internal laws of the State of New York, for a fixed sum would be recognized and enforced by a court of competent jurisdiction in the Province of Alberta, if (i) the courts of the Province of Alberta concluded that there is a real and substantial connection between the action and the jurisdiction of the court rendering judgment; (ii) such judgment was not obtained in a manner contrary to natural justice and the enforcement thereof would not be inconsistent with public policy, as such term is understood under the laws of the Province of Alberta or contrary to any order made by the Attorney General of Canada under the Foreign Extraterritorial Measures Act (Canada) or by the Competition Tribunal under the Competition Act (Canada), or contrary to any express terms of these Acts; (iii) the enforcement of such judgment would not constitute, directly or indirectly, the enforcement of foreign revenue, penal or public laws; (iv) the foreign court did not assume jurisdiction as a result of a fraud practiced on the court; (v) there is no new evidence that the judgment was obtained by fraud as to the merits of the claim which was not discoverable with due diligence before the foreign judgment was granted; and (vi) there has been compliance with the applicable limitation period; provided, however, that interest payable on a judgment debt may be limited by the proper or governing law of the respective contract or obligation and that a monetary judgment of a court of the Province of Xxxxxxx xxx only be awarded in Canadian currency and that the enforceability thereof may be limited by applicable bankruptcy, insolvency or other laws of general application limiting the enforcement of creditors’ rights generally. We have no reason to believe that the enforcement of any such judgment in respect of the Agreement, the Indenture or the Securities would be inconsistent with public policy as such term is understood under Applicable Law;

IIa-2

(xiv) in the event that any of the Agreement, the Indenture or the Securities is sought to be enforced in any action or proceedings in the Province of Alberta in accordance with the laws applicable thereto as chosen by the parties, namely the laws of the State of New York, the courts of the Province of Alberta would recognize such choice of laws, provided that such choice of laws was bona fide and legal and not made with a view to avoiding the consequences of the laws of any other jurisdiction and provided that such choice is not contrary to public policy as such term is understood under Applicable Law. We have no reason to believe that such choice of laws was made for the purpose of avoiding the consequences of the laws of any other jurisdiction or that such choice of laws would be inconsistent with public policy as such term is understood under Applicable Law;

(xv) in the event that any of the Agreement, the Indenture or the Securities is sought to be enforced in any action or proceeding in the Province of Alberta in accordance with the laws applicable thereto as chosen by the parties, namely the laws of the State of New York, the courts of the Province of Alberta would, subject to paragraph (xiv) above, apply the laws of the State of New York, upon appropriate evidence as to such laws being adduced, to all issues that, under the conflict of laws rules of Applicable Law, are to be determined in accordance with the proper or governing law of the respective contract or obligation, provided that none of the provisions of the applicable document or the laws of the State of New York are contrary to public policy as such term is understood under Applicable Law and that performance is not illegal under the laws of the place where the obligations thereunder are to be performed; and further provided, however, that interest payable on a judgment debt may be limited by the proper or governing law of the respective contract or obligation and that a monetary judgment of a court of the Province of Xxxxxxx xxx only be awarded in Canadian currency. A court in the Province of Alberta has, however, an inherent power to decline to hear such an action or proceeding if it is contrary to public policy, as such term is understood under Applicable Law for it to do so, or if it is not the proper forum to hear such action, or if concurrent proceedings are brought elsewhere. We have no reason to believe that any of the provisions of the Agreement, the Indenture or the Securities are contrary to public policy as such term is understood under Applicable Law or that it would be inconsistent with public policy as such term is understood under Applicable Law for a court of the Province of Alberta to hear an action or proceeding to enforce the Agreement, the Indenture or the Securities;

(xvi) the submission by the Company to the non-exclusive jurisdiction of the New York Courts, contained in the Agreement, the Indenture and the Securities, would be recognized and given effect by the courts of the Province of Alberta as a valid submission to the jurisdiction of such courts, provided that the applicable provisions, if any, of the Agreement, the Indenture and the Securities, respectively, respecting service of process on the Company are duly complied with; and

(xvii) the courts in the Province of Alberta would recognize the appointment by the Company of TransCanada PipeLine USA Ltd. as its agent for service of process in the United States of America under the Agreement, the Indenture and the Securities.

Such counsel will state that they participated in the preparation of the Company’s most recently filed Annual Information Form, required under Canadian securities law, and in connection with the preparation by the Company of the Final Prospectus and the Canadian Disclosure Package, had discussions with certain officers and other representatives of the Company, representatives of the independent chartered accountants for the Company, the Underwriters and representatives of the Underwriters at which the contents of the Canadian Final Prospectus and the Canadian Disclosure Package were discussed to a limited extent. Given the limitations inherent in the independent verification of factual matters and the character of determinations involved in the qualification process, such counsel may state that they have not verified, and are not passing upon and do not assume any responsibility for, the accuracy, completeness or genuineness or fairness of the statements contained in the Canadian Final Prospectus and the Canadian Disclosure Package (other than as explicitly stated in paragraph (viii) above) and have made no independent check or verification thereof.

IIa-3

Subject to the foregoing and in the course of such participation (and relying as to materiality as to factual matters to the extent such counsel deems reasonable on officers, employees and other representatives of the Company), such counsel will state that no facts have come to such counsel’s attention that caused them to believe that the Basic Prospectus, insofar as it relates to the offering of the Securities, at the time a final receipt was issued therefor on the date of this Agreement, and on the date of filing of any amendment or supplement to the Basic Prospectus with the Reviewing Authority prior to the date of such opinion, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading. Also, subject to the foregoing, such counsel will state that no facts have come to such counsel’s attention in the course of the proceedings described above that cause them to believe that (a) the Canadian Final Prospectus as of the date of its filing with the Reviewing Authority and as of the time of delivery of such opinion or (b) the Canadian Disclosure Package as of the Initial Sale Time and as of the time of delivery of such opinion contained or contains, as the case may be, any untrue statement of a material fact or omitted or omits, as the case may be, to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. In each case, counsel need not express any belief as to (i) financial statements, financial statement schedules and other financial and statistical information or data included or incorporated by reference in or omitted from the Basic Prospectus and the Canadian Final Prospectus or (ii) discussions of the regulation of the Company’s business under the federal and provincial laws of Canada or the United States in documents filed with the Reviewing Authority or filed with the Commission and incorporated by reference in the Basic Prospectus or Canadian Final Prospectus.

In giving the opinions described above, such counsel may (A) exclude from such opinions the effect or applicability of any United States or Canadian federal, provincial, territorial, state and local laws, rules or regulations relating to the regulation of the generation, transportation, distribution or delivery of natural gas, oil, electricity or other specially regulated commodities or services, including pipelines, transmission lines, storage facilities and related facilities and equipment, or the import or export of such commodities or services, including without limitation activities, businesses, operations or assets of the Company and its subsidiaries regulated by or subject to the jurisdiction of (i) the Canadian National Energy Board, (ii) the Alberta Utilities Commission or (iii) the Alberta Energy and Resources Conservation Board, (B) state that the opinions above are limited to the laws of the Province of Alberta and the federal laws of Canada therein, (C) rely solely upon the opinion of Xxxxx Xxxxx LLP to be delivered pursuant to Section 5(b) of this Agreement with respect to all matters relating to the laws of the United States and the State of New York and (D) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials. In addition, in connection with the belief expressed above, such counsel may assume that the terms “material fact” and “misleading” have the same interpretation under United States law as the same have under the Alberta Securities Act. It is understood that such counsel may state, in connection with the statements referred to in the foregoing paragraph, (i) that under the Securities Act (Alberta), a “material fact”, where used in relation to securities issued or proposed to be issued, means a fact that would reasonably be expected to have a significant effect on the market price or value of such securities, (ii) that such counsel is not qualified to judge the impact that any facts may have in the securities marketplace and (iii) that the statements in the foregoing paragraph are based solely upon the knowledge of such counsel’s partners and associates involved in representing the

IIa-4

Company in connection with the Offering. It is further understood that such counsel may state, in connection with the statements referred to in the foregoing paragraph, that such counsel’s statements are based on: (a) such counsel’s experience in practicing Alberta securities law; (b) the meaning of the term “material fact” as stated above; and (c) the opinions of officers and other representatives of the Company and representatives of the Underwriters, and should not be interpreted as an opinion or expert comment in respect of financial, accounting or statistical facts or the impact of any facts on market prices or values of securities.
