(collectively, the “Selling Securityholders”) propose to sell 4,000,000 shares of common stock (the “Common Stock”) of Aviall, Inc.

The firm listed on Schedule A hereto is hereinafter referred to as the “Underwriter”.

Such registration statement, as amended as of the date of this Agreement, is hereinafter referred to as the “Registration Statement”, and the prospectus included in such Registration Statement, as supplemented by the prospectus supplement reflecting the terms of the offering of the Offered Securities to be filed (the “Filing”) with the Commission on or about February 10, 2005 pursuant to and in accordance with Rule 424(b) (“Rule 424(b)”) under the Securities Act of 1933, as amended (the “Act”), including all material incorporated by reference therein as of the date of such filing, is hereinafter referred to as the “Prospectus”. No document has been or will be prepared or distributed in reliance on Rule 434 under the Act.

(ii) On the effective date of the Registration Statement and as of the date hereof, the Registration Statement and the Prospectus (including all material incorporated by reference therein prior to the Filing) conformed and conforms in all material respects to the requirements of the Act and the rules and regulations of the Commission (the “Rules and Regulations”) and did not and does not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, except that the foregoing does not apply to (statements in or omissions from any of such documents based upon written information furnished to the Company by (i) the Underwriter, if any, specifically for use therein or (ii) the Selling Securityholders, if any, specifically for use therein).

(iii) The Company has been duly incorporated and is an existing corporation in good standing under the laws of the State of Delaware, with full corporate power and authority to own its properties and conduct its business as described in the Prospectus; and the Company is duly qualified to do business as a foreign corporation in good standing in each jurisdiction in which its ownership or lease of property or the conduct of its business requires such qualification, except

where the failure to be so qualified (i) could not reasonably be expected to have a material adverse effect on the performance of this Agreement or the consummation of any of the transactions contemplated hereby, or (ii) could not reasonably be expected to have a material adverse effect on the business, properties, condition (financial or otherwise), results of operations of the Company and its Subsidiaries (as defined below) taken as a whole (the occurrence of events described in clause (ii) being referred to herein as a “Material Adverse Effect”). “Subsidiary” shall mean in respect of any Person, any corporation, company (including any limited liability company), association, partnership, joint venture, trust, unincorporated organization or other business entity of which a majority of the total voting power of all classes of capital stock and other equity interests of such entities then outstanding and normally entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers or trustees thereof, is at the time owned or controlled, directly or indirectly, by: (a) such Person, (b) such Person and one or more Subsidiaries of such Person, or (c) one or more Subsidiaries of such Person; provided that “Subsidiary” shall exclude any entity that conducts no business activities.

(iv) Each Subsidiary of the Company has been duly incorporated or organized and is an existing corporation or limited liability company in good standing under the laws of the jurisdiction of its incorporation or organization, with full corporate or limited liability company power and authority to own its properties and conduct its business as described in the Prospectus; and each Subsidiary of the Company is duly qualified to do business as a foreign corporation or limited liability company in good standing in each jurisdiction in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be in good standing or so qualified (i) could not reasonably be expected to have a material adverse effect on the performance of this Agreement or the consummation of any of the transactions contemplated hereby, or (ii) could not reasonably be expected to have Material Adverse Effect.

(v) All of the outstanding shares of capital stock of each Subsidiary of the Company have been duly authorized and validly issued and are fully paid and nonassessable; and the outstanding shares of capital stock of each Subsidiary are owned by the Company, directly or through Subsidiaries, free from liens and encumbrances, except those created pursuant to that certain Second Amended and Restated Credit Agreement, dated as of June 30, 2003, among Aviall Services, Inc., the Company, the lenders party thereto and Citicorp USA, Inc., as Administrative Agent, as amended to date.

(vi) The Offered Securities and all other outstanding shares of capital stock of the Company have been duly authorized, validly issued, fully paid and nonassessable; and conform in all material respects to the description thereof contained in the Prospectus. The stockholders of the Company do not have any preemptive rights with respect to the issuance of additional shares of the Company’s common stock.

(vii) Except as disclosed in the Prospectus, there are no contracts, agreements or understandings between the Company and any person that would give rise to a valid claim against the Company or any Subsidiary of the Company for a brokerage commission, finder’s fee or other like payment in connection with the sale of the Offered Securities.

(viii) There are no contracts, agreements or understandings between the Company and any person granting such person the right to require the Company to file a registration statement under the Act with respect to any securities of the Company owned or to be owned by such person or to require the Company to include such securities in the securities registered pursuant to the Registration Statement or in any securities being registered pursuant to any other registration statement filed by the Company under the Act, other than those held by the Selling Securityholders and their affiliates.

(ix) The Offered Securities have been listed on the New York Stock Exchange.

(xi) The execution, delivery and performance of this Agreement, the consummation of the transactions contemplated herein and the sale of the Offered Securities will not result in a breach or violation of any of the terms and provisions of, or constitute a default under, any statute, any rule, regulation or order of any governmental agency or body or any court having jurisdiction over the Company or any Subsidiary of the Company or any of their properties, or any agreement or instrument to which the Company or any such Subsidiary is a party or by which the Company or any such Subsidiary is bound or to which any of the properties of the Company or any such Subsidiary is subject, or the charter, by-laws or other organizational documents of the Company or any such Subsidiary; except for such breaches, violations and defaults that (i) could not reasonably be expected to have a material adverse effect on the performance of this Agreement or the consummation of any of the transactions contemplated hereby, or (ii) could not reasonably be expected to have a Material Adverse Effect.

The Company and its Subsidiaries have not received any notice of infringement of or conflict with asserted rights of others with respect to any intellectual property rights that, if determined adversely to the Company or any of its Subsidiaries, could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

7

statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Prospectus to comply with the Act, the Selling Securityholders will promptly notify the Underwriter and the Company of such event.

(c) The Underwriter will indemnify and hold harmless the Company, the Selling Securityholders, their respective directors and officers and each person, if any, who controls the Company or any of the Selling Securityholders within the meaning of Section 15 of the Act against any losses, claims, damages or liabilities to which the Company or the Selling Securityholders may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, or arise out of or are based upon the omission or the alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company by the Underwriter specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company and the Selling Securityholders in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by the Underwriter consists of the name of the Underwriter, the pricing information set forth on the cover page and the last paragraph under the caption “Underwriting” in the Prospectus.

(d) Promptly after receipt by an indemnified party under this Section 6 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under subsection (a), (b) or (c) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a), (b) or (c) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may

10

have to an indemnified party otherwise than under subsection (a), (b) or (c) above. In case any such action is brought against any indemnified party and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, which shall not be unreasonably withheld, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, which shall not be unreasonably withheld, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a), (b) or (c) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a), (b) or (c) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Securityholders on the one hand and the Underwriter on the other hand from the offering of the Offered Securities or (ii) if 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 and the Selling Securityholders on the one hand and the Underwriter on the other hand in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Securityholders on the one hand and the Underwriter on the other hand shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Securityholders bear to the total underwriting discounts and commissions received by the Underwriter. 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 Company, the Selling Securityholders or the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (e) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (e). Notwithstanding the provisions of this subsection (e), the Selling Securityholders shall not be required to contribute any amount in excess of an amount equal to the net proceeds to the Selling Securityholders from the sale of Offered Securities hereunder. 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.

(f) The obligations of the Company and the Selling Securityholders under this Section shall be in addition to any liability which the Company and the Selling Securityholders may otherwise have and shall extend, upon the same terms and conditions, to each partner, director and officer of, and each person, if any, who controls, the Underwriter within the meaning of the Act; and the obligations of the Underwriter under this Section shall be in addition to any liability which the Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement and to each person, if any, who controls the Company within the meaning of the Act.

The respective indemnities, agreements, representations, warranties and other statements of the Selling Securityholders, the Company or its officers and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriter, the Selling Securityholder, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If for any reason the purchase of the Offered Securities by the Underwriter is not consummated, the Company and the Selling Securityholders shall remain responsible for the expenses to be paid or reimbursed by them pursuant to Section 4 and the respective obligations of the Company, the Selling Securityholders and the Underwriter pursuant to Section 6 shall remain in effect. If the purchase of the Offered Securities by the Underwriter is not consummated as a result of a failure by the Company to fulfill any of the conditions precedent contained in Sections 5(b), (c)(i), (c)(ii), (c)(v), and (h) or a failure by the Company to fulfill its obligations under this Agreement for any other reason, then the Company shall reimburse the Underwriter for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by it in connection with the offering of the Offered Securities. If the purchase of the Offered Securities by the Underwriters is not consummated as a result of a failure by the Selling Stockholders to fulfill any of the conditions precedent contained in Sections 5(i) and 5(j) or a refusal by the Selling Stockholders to consummate the sale of the Offered Securities for any other reason, then the Selling Stockholders shall reimburse the Underwriter for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by it in connection with the offering of the Offered Securities.
