(g) Neither the Company nor any of its subsidiaries shall have sustained since the date of the latest audited financial statements included in the Prospectus (A) any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus or (B) since such date there shall not have been any change in the capital stock or any material increase in the long-term debt of the Company or any of its subsidiaries (other than in the ordinary course of business) or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position, stockholders' equity or results of operations of the Company and its subsidiaries, otherwise than as set forth or contemplated in the Prospectus, the effect of which, in any such case described in clause (A) or (B), is, in the reasonable judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Stock being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus. (h) Subsequent to the execution and delivery of this Agreement (i) no downgrading shall have occurred in F the rating accorded the Company's debt securities by any "NATIONALLY RECOGNIZED STATISTICAL RATING ORGANIZATION", as that term is defined by the Commission for purposes of Rule 436(g)(2) of the Rules and Regulations and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Company's debt securities. -15- (i) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) (A) trading in securities generally on the New York Stock Exchange, the American Stock Exchange or the Nasdaq National Market shall have been suspended or materially limited, (B) a banking moratorium in New York or Missouri shall have been declared by Federal, New York or Missouri authorities, (C) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States, or (D) there shall have occurred a material adverse change in general economic, political or financial conditions (or the effect of international conditions on the financial markets in the United States shall be such), and (ii) the effect of the event in (i)(C) or (D) would, in the reasonable judgment of the Representatives, make it impracticable or inadvisable to proceed with the public offering or delivery of the Stock being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus. (j) The New York Stock Exchange, Inc. shall have approved the Stock for listing, subject only to official notice of issuance.

Section 8. INDEMNIFICATION AND CONTRIBUTION. (a) The Company shall indemnify and hold harmless each Underwriter, its officers and employees and each person, if any, who controls any Underwriter within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which that Underwriter, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained (A) in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto, or (B) in any materials or information provided electronically to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Stock ("MARKETING MATERIALS"), including any road show or investor presentations made to investors by the Company (where such presentations are made electronically and not in person), or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, or in any Marketing Materials, any material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Stock or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Company shall not be liable under this clause (iii) to the extent that it is determined by an independent third party that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its negligence or willful misconduct), and shall reimburse each Underwriter and each such officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such -16- loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any such amendment or supplement, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein which information consists solely of the information specified in Section 8(e), and provided, further, that with respect to any such untrue statement in or omission from the Preliminary Prospectus, the indemnity agreement contained in this Section 8(a) shall not inure to the benefit of an Underwriter to the extent that the sale to the person asserting any such loss, claim, damage, liability or action was an initial resale by the Underwriter and any such loss, claim, damage, liability or action of or with respect to the Underwriter results from the fact that both (A) to the extent required by applicable law, a copy of the Prospectus was not sent or given to such person at or prior to the written confirmation of the sale of such Shares to such person and (B) the untrue statement in or omission from the Preliminary Prospectus was corrected in the Prospectus unless, in either case, such failure to deliver the Prospectus was a result of non-compliance by the Company with Section 5(c). The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to any Underwriter or to any officer, employee or controlling person of that Underwriter. In connection with the offer and sale of the Directed Shares, the Company agrees, promptly upon a request in writing, to indemnify and hold harmless Lehman Brothers Inc. and the other Underwriters from and against any loss, claim, damage, expense, liability or action which (i) arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the approval of the Company for distribution to Participants in connection with the Directed Share Program or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) arises out of the failure of any Directed Share Program participant to pay for and accept delivery of Directed Shares that the Participant agreed to purchase or (iii) is otherwise related to the Directed Share Program, other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted directly from the bad faith or gross negligence of Lehman Brothers Inc. or the other Underwriters. (b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, its officers and employees, each of its directors, and each person, if any, who controls the Company within the meaning of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, and shall reimburse the Company and any such director, officer, employee or controlling person for any legal or other expenses reasonably incurred by the Company or any such director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Company or any such director, officer, employee or controlling person. -17- (c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure and, provided further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying parties, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Representatives shall have the right to employ counsel to represent jointly the Representatives and those other Underwriters and their respective officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Company under this Section 8 if, the named parties to any such claim (including impleaded parties) include both such Representative, any Underwriter or any officer, employee or controlling person of a Representative or Underwriter and the Company, and the Representatives are advised in writing by counsel that representation of such indemnified party and the Company by the same counsel will be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them. It is understood, however, that in connection with any one such action, suit or proceeding or separate but substantially similar or related actions, suits or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, the indemnifying party shall be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel) at any time for all such indemnified parties not having actual or potential differing interests, which firm shall be designated in writing. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 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, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. (d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Stock or (ii) if -18- the allocation provided by clause (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 (i) above but also the relative fault of the Company on the one hand and the Underwriters on the other with respect to the statements or omissions which resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Company, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the shares of the Stock purchased under this Agreement, on the other hand, bear to the total gross proceeds from the offering of the shares of the Stock under this Agreement, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Stock underwritten by it and distributed to the public was offered to the public exceeds the amount of any damages which such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint. (e) The Underwriters severally confirm and the Company acknowledges that the statements with respect to the public offering of the Stock by the Underwriters set forth (i) on the cover page of the Prospectus and (ii) such information under the caption "Underwriting" in the Prospectus relating to (A) any concession and reallowance figures including the public offering price and any underwriting discount or commission, (B) the allocation of shares to the Underwriters, (C) agreements among the Underwriters and not the Company, (D) factors considered in determining the initial public offering price, (E) stabilizing transactions, (F) representations of the international underwriters, (G) the role of Fidelity Capital Markets in this offering and (H) the Underwriters' intention to not confirm sales, are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement and the Prospectus. Section 9. DEFAULTING UNDERWRITERS. If, on either Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Stock which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of -19- shares of the Firm Stock set opposite the name of each remaining non-defaulting Underwriter in SCHEDULE 1 and SCHEDULE 2 hereto bears to the total number of shares of the Firm Stock set forth opposite the names of all the remaining non-defaulting Underwriters in SCHEDULE 1 and SCHEDULE 2 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Stock on such Delivery Date if the total number of shares of the Stock which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10.0% of the total number of shares of the Stock to be purchased on such Delivery Date. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives and the Company who so agree, shall have the right (exercisable within 72 hours of the initial default), but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Stock to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives and the Company do not elect to purchase the Stock which the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to the Second Delivery Date, the obligation of the Underwriters to purchase, and of the Company to sell, the Option Stock) shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11. As used in this Agreement, the term "UNDERWRITER" includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 or 2 hereto who, pursuant to this Section 9, purchases Stock which a defaulting Underwriter agreed but failed to purchase. Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other Underwriters are obligated or agree to purchase the Stock of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement. Section 10. TERMINATION. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Sections 7(h), 7(i) or 7(j), shall have occurred or if the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement. Section 11. REIMBURSEMENT OF UNDERWRITERS' EXPENSE. If the Company shall fail to tender the Stock for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company to perform any agreement on its part to be performed, or because any other condition of the Underwriters' obligations hereunder required to be fulfilled by the Company is not fulfilled, the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Stock, and upon demand the Company shall pay the full amount thereof to the Representatives.

As Representatives of the several International Underwriters named in Schedule 2, c/o Lehman Brothers International (Europe) One Broadgate London EC2M 7HA England and Merrill Lynch International World Financial Center--North Tower New York, New York 10281-1327 Dear Sirs: The undersigned understands that you and certain other firms propose to enter into an Underwriting Agreement (the "UNDERWRITING AGREEMENT") providing for the purchase by you and such other firms (the "UNDERWRITERS") of shares (the "SHARES") of Class A Common Stock, par value $0.01 per share, of Aquila, Inc., a Delaware corporation (the "COMPANY"), and that the Underwriters propose to reoffer the Shares to the public (the "OFFERING"). In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Lehman Brothers Inc. on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any shares of the common stock of the Company (including, without limitation, the Shares and shares of the common stock of the Company that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities A-1 and Exchange Commission and shares of the common stock of the Company that may be issued upon exercise of any option or warrant) or securities convertible into or exchangeable for the common stock of the Company owned by the undersigned on the date of execution of this Lock-Up Letter Agreement or on the date of the completion of the Offering, or (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such shares of the common stock of the Company, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of the common stock of the Company or other securities, in cash or otherwise, for a period of 180 days after the date of the final Prospectus relating to the Offering, except that the undersigned may make gifts of such securities to members of the undersigned's "immediate family" (as such term is defined under Item 404 of Regulation S-K under the Securities Act of 1933) or transfer such securities to one or more trusts established for the benefit of members of the undersigned's immediate family and make involuntary transfers; provided, that any such transferee agrees in writing to be bound by the terms hereof. In furtherance of the foregoing, the Company and its Transfer Agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement. It is understood that, if the Company notifies you that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Shares, we will be released from our obligations under this Lock-Up Letter Agreement. The undersigned understands that the Company and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement. Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters. The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.
