(4) The U.S. Underwriters' obligations under this agreement are conditional upon and subject to the Corporation causing its auditors to deliver to the U.S. Underwriters a comfort letter, dated the Closing Date, in form and substance satisfactory to the U.S. Underwriters, acting reasonably, bringing forward to a date not more than two business days prior to the Closing Date the information contained in the comfort letter referred to in paragraph 9(1)(a). Section 11 Closing of U.S. Underwriters' Option (1) The purchase and sale of the Additional Units shall be completed at such time and place as the U.S. Underwriters and the Corporation may agree, but in no event shall such closing occur later than five full business days after written notice of election to purchase Additional Units under the U.S. Underwriters' Option is given in the manner contemplated by the second paragraph of this Agreement (the "Over-Allotment Closing"). (2) At the Over-Allotment Closing, subject to the terms and conditions contained in this agreement, the Corporation shall deliver to the U.S. Underwriters a certificate or certificates representing the Additional Units against payment of the purchase price by certified cheque, bank draft or wire transfer dated the date of the Over-Allotment Closing payable to the Corporation. The Corporation will, at the time of the Over- -15- Allotment Closing and upon such payment of the purchase price to the Corporation, make payment in full of the Underwriting Fee in respect of the Additional Units. Section 12 Termination Rights (1) All terms and conditions set out herein shall be construed as conditions and any breach or failure by the Corporation to comply with any such conditions in favour of the U.S. Underwriters shall entitle the U.S. Underwriters to terminate their obligation to purchase the Securities by written notice to that effect given to the Corporation prior to the Time of Closing on the Closing Date. The Corporation shall use its reasonable best efforts to cause all conditions in this agreement to be satisfied. It is understood that the U.S. Underwriters may waive in whole or in part, or extend the time for compliance with, any of such terms and conditions without prejudice to their rights in respect of any subsequent breach or non-compliance, provided that to be binding on the U.S. Underwriters, any such waiver or extension must be in writing. (2) In addition to any other remedies which may be available to the U.S. Underwriters, the U.S. Underwriters shall be entitled, at their option, to terminate and cancel, without any liability on the U.S. Underwriters' part, their obligations under this agreement to purchase the Securities, by giving written notice to the Corporation at any time at or prior to the Time of Closing on the Closing Date: (a) if there should occur any suspension or limitation of trading in securities generally on the TSX or AMEX, or if a general moratorium on commercial banking activities in Toronto or New York should be declared by the relevant authorities, or if, in relation to the Corporation, any inquiry, investigation or other proceeding (whether formal or informal) is commenced, threatened or announced or any order or ruling is issued by any officer of such exchange or market, or by the SEC, or any other regulatory authority in Canada or the United States, or if any law or regulation under or pursuant to any statute of Canada or of any province thereof or of the United States or any state or territory thereof is promulgated or changed which, in the reasonable opinion of the U.S. Underwriters (or any of them) operates to prevent or materially restrict trading the Common Shares or the distribution of the Securities or could reasonably be expected to have a material adverse effect on the market price of the Common Shares or the Securities; (b) if there shall occur any actual material adverse change or change in the business, affairs, operations, assets, liabilities or financial condition of the Corporation on a consolidated basis which in the U.S. Underwriters' reasonable opinion would reasonably be expected to have a material adverse effect on the market price or value of any of Securities or the Common Shares; or (c) if there should develop, occur or come into effect or existence any event, action, state, condition or major financial occurrence of national or international consequence, without limiting the generality of the foregoing, any military conflict, civil insurrection, or any terrorist action, including, without limitation, military insurrection (whether or not in connection with such conflict or -16- insurrection), which, in the U.S. Underwriters' reasonable opinion, materially adversely affects or involves, or will materially adversely affect or involve, the Canadian or United States financial markets and/or prevents or materially restricts the trading of the Common Shares or the distribution of the Securities; (3) The U.S. Underwriters shall make reasonable best efforts to give notice to the Corporation (in writing or by other means) of the occurrence of any of the events referred to in clauses 12(2)(a), (b) or (c) provided that neither the giving nor the failure to give such notice shall in any way affect the entitlement of the U.S. Underwriters to exercise this right at any time prior to or at the Time of Closing. (4) The rights of termination contained in this section may be exercised by the U.S. Underwriters and are in addition to any other rights or remedies the U.S. Underwriters may have in respect of any default, act or failure to act or non-compliance by the Corporation in respect of any of the matters contemplated by this agreement. (5) If the obligations of the U.S. Underwriters are terminated under this agreement pursuant to these termination rights, the Corporation's liabilities to the U.S. Underwriters shall be limited to the Corporation's obligations under Sections 13, 14 and 15. Section 13 Indemnity (1) The Corporation agrees to indemnify and hold harmless each U.S. Underwriter, and their respective directors, officers, employees and agents, and each person, if any, who controls any U.S. Underwriter within the meaning of Section 15 of the U.S. Securities Act or Section 20 of the U.S. Exchange Act against any and all losses, claims, damages and liabilities, joint or several (including any investigation, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted), to which they, or any of them, may become subject under the U.S. Securities Act, at common law or otherwise, insofar as such losses, claims, damages or liabilities arise out of or are based upon (i) any material breach of a representation or warranty of the Corporation contained herein or the failure of the Corporation to comply with any of its obligations hereunder, in all material respects, or (ii) any untrue statement or alleged untrue statement of a material fact contained in the U.S. Shelf Preliminary Prospectus Supplement, the U.S. Shelf Prospectus Supplement or the U.S. Registration Statement, or any amendment or supplement thereto, or 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, except insofar as any such untrue statement or omission or alleged untrue statement or omission was made in such U.S. Shelf Preliminary Prospectus Supplement, the U.S. Shelf Prospectus Supplement or U.S. Registration Statement, or such amendment or supplement, in reliance upon and in conformity, with information furnished in writing to the Corporation by or on behalf of any U.S. Underwriter or Canadian Underwriter expressly for use in the preparation thereof; provided, however, that the foregoing indemnity against losses, claims, damages or liabilities is subject to the condition that, insofar as it relates to any untrue statement or alleged untrue statement, omission or alleged omission made in the U.S. Registration Statement or the U.S. Shelf Preliminary -17- Prospectus Supplement but eliminated or remedied in the U.S. Shelf Prospectus Supplement, such indemnity shall not inure to the benefit of any U.S. Underwriter from whom the person asserting any loss, claim, damage or liability purchased the Securities which are the subject thereof (or to the benefit of any person who controls such U.S. Underwriter) if such U.S. Underwriter failed to send or give a copy of the U.S. Shelf Prospectus Supplement (or any amendment or supplement thereto) to such person at or prior to the time such action is required by the U.S. Securities Act. (2) Each U.S. Underwriter agrees to indemnify and hold harmless the Corporation, each person, if any, who controls the Corporation within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each director of the Corporation and each officer of the Corporation, to the same extent as the foregoing indemnity from the Corporation to each Underwriter, but only insofar as such losses, claims, damages or liabilities arise out of or are based upon any untrue statement or omission or alleged untrue statement or omission which was made in the U.S. Shelf Preliminary Prospectus Supplement or the U.S. Shelf Prospectus Supplement, or any amendment or supplement thereto, in reliance upon and in conformity with information furnished in writing to the Corporation by such U.S. Underwriter with respect to the U.S. Underwriters expressly for use in the preparation thereof. (3) Any party which proposes to assert the right to be indemnified under this Section 13 will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim is to be made against an indemnified party under this Section 13, notify each such indemnifying party of the commencement of such action, suit or proceeding, enclosing a copy of all papers served, but the omission so to notify such indemnifying party of any such action, suit or proceeding shall not relieve it from any liability which it may have to any indemnified party otherwise than under this Section 13. In case any such action, suit or proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defence thereof, with counsel satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defence thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses, other than reasonable costs of investigation subsequently incurred by such indemnified party in connection with the defence thereof. The indemnified party shall have the right to employ its counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party has been authorized by the indemnifying parties, (ii) the indemnified party shall have reasonably concluded that there may be a conflict of interest between the indemnifying parties and the indemnified party in the conduct of the defence of such action (in which case the indemnifying parties shall not have the right to direct the defence of such action on behalf of the indemnified party) or (iii) the indemnifying parties shall not in fact have employed counsel to assume the defence of such action. An indemnifying party shall not be liable for any settlement of any action or claim effected without its consent. For the purposes of clause (ii) of the preceding sentence only, any indemnified party or -18- parties shall be represented by one counsel whom they may select with the approval, which shall not be unreasonably withheld, of the indemnifying parties. Section 14 Contribution In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in Section 13 is applicable but for any reason, other than as specified in Section 13, is held to be unavailable from the indemnifying party, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the aggregate losses, claims, damages and liabilities (including any investigation, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted), in such proportion as is appropriate to reflect the relative benefits received by the Corporation on the one hand and the U.S. Underwriters on the other from the offering of the Securities. If however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Corporation on the one hand and the U.S. Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Corporation on the one hand and the U.S. Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering of the Securities (before deducting expenses) received by the Corporation bear to the total underwriting discounts and commissions received by the U.S. Underwriters, in each case as set forth in the U.S. Shelf Prospectus Supplement. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Corporation on the one hand or the U.S. Underwriters on the other and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Corporation and the U.S. Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 14 were determined by pro rata allocation (even if the U.S. Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 14. Notwithstanding the provisions of this Section 14, (i) in no case shall any U.S. Underwriter be responsible for any amount in excess of the sum of the Underwriting Fee applicable to the Securities purchased by such U.S. Underwriter hereunder, and (ii) 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. For purposes of this Section 14, each person, if any, who controls a U.S. Underwriter within the meaning of the U.S. Securities Act and the U.S. Exchange Act, and each director, officer, employee and agent of a U.S. Underwriter shall have the same rights to contribution as such U.S. Underwriter, and each person, if any, who controls the Corporation within the meaning of the U.S. Securities Act and the U.S. Exchange Act, and each director of the Corporation shall have the same rights to contribution as the Corporation, subject in each case to clauses (i) and (ii) of this Section 14. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties under this Section 14, notify such party or parties from whom contribution may be sought, but the -19- omission so to notify such party or parties from whom contribution may he sought shall not relieve the party or parties from whom contribution may be sought from any other obligation it or they may have hereunder or otherwise than under this Section 14. No party shall be liable for contribution with respect to any action or claim settled without its written consent. The U.S. Underwriters' obligations in this section to contribute are several in proportion to their respective obligations and not joint. Section 15 Expenses Whether or not the transactions provided for herein (including the Offering) are completed, the Corporation shall pay all costs, fees and expenses of or incidental to the performance of its obligations under this agreement including, without limitation: (i) the costs of the Corporation's professional advisors, (ii) the cost of printing the U.S. Shelf Preliminary Prospectus Supplement, the U.S. Shelf Prospectus Supplement, (iii) the preparation of any Blue Sky survey regarding the offers and sales of the Securities in the various states, and (iv) the fees and expenses of the Corporation's auditors, counsel and any local counsel. Except as provided in this agreement (including clause (iii) above), the fees and disbursements of any counsel to the U.S. Underwriters and out-of-pocket expenses of the U.S. Underwriters shall be borne by the U.S. Underwriters; provided that in the event that the sale and purchase of the Securities is not completed in accordance with the terms hereof (other than as a result of a breach by the U.S. Underwriters of any of its obligations hereunder or the exercise by the U.S. Underwriters of the termination rights contained herein), the Corporation shall assume and pay the out-of-pocket expenses of the U.S. Underwriters and the reasonable fees and disbursements of counsel to the U.S. Underwriters. Section 16 Liability of U.S. Underwriters (1) The obligation of the U.S. Underwriters to purchase the Securities in connection with the Offering at the Time of Closing on the Closing Date shall be several and not joint or joint and several and shall be as to the following percentages of the Offered Securities to be purchased at that time: BMO Nesbitt Burns Corp. 60% NBC International (USA) Inc. 40% ---- 100% (2) If one of the U.S. Underwriters fails to purchase its applicable percentage of the aggregate amount of the Offered Securities at the Closing Time, the other U.S. Underwriter shall have the right, but shall not be obligated, to purchase, all but not less than all, of the Offered Securities which would otherwise have been purchased by the U.S. Underwriter which failed to purchase. If, with respect to the Offered Securities, any non-defaulting U.S. Underwriter elects not to exercise such right so as to assume the entire obligation of the defaulting U.S. Underwriter (the Offered Securities in respect of which the defaulting Underwriter(s) fail to purchase and the non-defaulting U.S. Underwriters does not elect to purchase being hereinafter called the "Default Shares"), then the Corporation shall have the right to either (i) proceed with the sale of the Offered Securities (less the Default Shares) to the non-defaulting U.S. Underwriter or (ii) terminate its obligations hereunder without liability to the non-defaulting U.S. -20- Underwriters except under sections 13, 14 and 15. Nothing in this paragraph shall oblige the Corporation to sell to any of the U.S. Underwriters less than all of the Offered Securities or shall relieve any of the U.S. Underwriters in default hereunder from liability to the Corporation. (3) Notwithstanding the foregoing, the U.S. Underwriters shall have the right, but not the obligation, to sell to the Canadian Underwriters, any Offered Securities pursuant to the Inter-Dealer Agreements, and subject to the terms and conditions set out therein. Section 17 Action by U.S. Underwriters All steps which must or may be taken by the U.S. Underwriters in connection with the agreement resulting from the Corporation's acceptance of this offer, with the exception of the matters relating to termination contemplated by Section 12, may be taken by the U.S. Lead Manager on behalf of itself and the other U.S. Underwriter and the acceptance of this offer by the Corporation shall constitute the Corporation's authority for accepting notification of any such steps from, and for delivering the definitive documents constituting the Securities to or to the order of the U.S. Lead Manager. Section 18 Governing Law; Time of Essence This agreement shall be governed by and construed in accordance with the laws of the State of New York and the federal laws of the United States of America applicable therein and time shall be of the essence hereof. Section 19 Survival of Warranties, Representations, Covenants and Agreements All warranties, representations, covenants and agreements of the Corporation and the U.S. Underwriters herein contained or contained in documents submitted or required to be submitted pursuant to this agreement shall survive the purchase by the U.S. Underwriters of the Securities and shall continue in full force and effect, regardless of the closing of the sale of the Securities and regardless of any investigation which may be carried on by the U.S. Underwriters, or on their behalf, for a period of three years following the Closing Date. Without limitation of the foregoing, the provisions contained in this agreement in any way related to the indemnification or the contribution obligations shall survive and continue in full force and effect, indefinitely. Section 20 Press Releases The Corporation shall provide the U.S. Underwriters and their counsel with a copy of all press releases to be issued by the Corporation concerning the offering contemplated hereby prior to the issuance thereof, and shall give the U.S. Underwriters and their counsel a reasonable opportunity to provide comments on any press release.

The term "rate of exchange" shall include any premiums and costs of exchange payable in connection with the purchase of or conversion into United States dollars.

Based solely on certificates from the Secretary of State of the State of Delaware, the Material Subsidiaries, other than Corp. Air Inc., are corporations subsisting and in good standing under the laws of the State of Delaware. 2. No authorization, approval or other action by, and no notice to, consent of, order of, or filing with, any United States Federal, New York or, to the extent required under the General Corporation Law of the State of Delaware, Delaware governmental authority or regulatory body is required for the consummation of the transactions contemplated by the U.S. Underwriting Agreement, except such as have been obtained under the U.S. Securities Act and such as may be required under the blue sky laws of any jurisdiction in connection with the purchase and distribution of the Securities by the U.S. Underwriters. 3. None of the issue and sale of the Securities, the consummation of any other of the transactions contemplated by the U.S. Underwriting Agreement and the performance of the terms of the U.S. Underwriting Agreement (i) will conflict with, result in a breach of, or constitute a default under any agreement or instrument that is listed as an exhibit to the Corporation's most recent Annual Report on Form 10-K filed with the SEC by the Corporation and to which the Corporation or any of its Material Subsidiaries is a party or bound, (ii) will contravene any law, rule or regulation of the United States of America or the State of New York or the General Corporation Law of the State of Delaware or (iii) based solely on a certificate signed by Lois-Ann L. Brodrick, Vice President and Secretary of the Corporation, on the date hereof, will contravene, to our knowledge, any order or decree of any court or government agency or instrumentality of the State of New York or the Federal government of the United States of America. In connection with the foregoing, we point out that certain of the agreements referred to in clause (i) above are or may be governed by laws other than the laws of the State of New York. For purposes of the opinion expressed in this paragraph, however, we have assumed that all such agreements are governed by and would be interpreted in accordance with the laws of the State of New York. 4. The statements made in the U.S. Shelf Prospectus Supplement under the caption "Plan of Distribution", insofar as they purport to summarize the material terms of the U.S. Underwriting Agreement, and under the caption "U.S. Federal Income Tax Considerations", insofar as they purport to describe the material tax consequences of an investment in Securities, fairly summarize the matters therein described. -3- 5. Based solely on a certificate signed by Lois-Ann L. Brodrick, Vice President and Secretary of the Corporation, on the date hereof, the Corporation is not, and after giving effect to the offering of the Securities and the application of the proceeds thereof as described in the U.S. Shelf Prospectus Supplement will not be, required to register as an "investment company" as such term is defined in the Investment Company Act of 1940, as amended. 6. The U.S. Registration Statement, at the time it was last amended or deemed to be amended, and the U.S. Shelf Prospectus, as of the date hereof (in each case except the financial statements and other information of a statistical, accounting or financial nature included therein, as to which we do not express any view), appeared on their face to be appropriately responsive in all material respects to the requirements of the U.S. Securities Act and the applicable rules and regulations thereunder.
