Ladies and Gentlemen:

Introduction. Allion Healthcare, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A hereto (the “Underwriters”), an aggregate of [ ] shares of the common stock, par value $0.001 per share, of the Company (the “Firm Shares”).

The Company also proposes to issue and sell to the several Underwriters not more than an additional [ ] shares of the Company’s common stock, par value $0.001 per share (the “Additional Shares”), if and to the extent that you shall have determined to exercise, on behalf of the Underwriters, the right to purchase such shares of common stock granted to the Underwriters in Section 2 hereof. The Firm Shares and the Additional Shares are hereinafter collectively referred to as the “Shares.” The shares of common stock, par value $0.001 per share, of the Company to be outstanding after giving effect to the sales contemplated hereby are hereinafter referred to as the “Common Stock.” Xxxxxx Xxxxxx Partners LLC, Xxxxxxx Xxxxx and Company and First Albany Inc. have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Shares.

The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”), in accordance with the provisions of the Securities Act of 1933, as amended (the “Securities Act”), and the applicable rules and regulations thereunder, a registration statement on Form S-1 (Commission File No. 333-124099), including a prospectus, relating to the Shares. The term “Registration Statement” as used herein means the registration statement including all financial schedules and exhibits incorporated or deemed to be incorporated by reference therein (but excluding any information or statements therein that were incorporated, or deemed to be incorporated by reference to the extent such information or statements have been modified or superceded by any statement in the prospectus, or in any other document that was subsequently filed with the Commission and incorporated by reference in the prospectus or Registration Statement) as amended at the time it becomes effective or, if the registration statement became effective prior to execution of this Agreement, as supplemented or amended prior to the execution of this Agreement and includes information (if any) contained in the form of final prospectus filed with the Commission pursuant to Rule 424(b) of the rules under the

Securities Act and deemed to be part thereof at the time of effectiveness pursuant to Rule 430A of the rules under the Securities Act. If it is contemplated, at the time this Agreement is executed, that a post-effective amendment to the registration statement will be filed and must be declared effective before the offering of the Shares may commence, the term “Registration Statement” as used herein means the registration statement as amended by said post-effective amendment. If the Company has filed, or files on or after the date of this Agreement, a registration statement to register additional shares of Common Stock pursuant to Rule 462(b) under the Securities Act (the “Rule 462(b) Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462(b) Registration Statement. The prospectus in the form first used to confirm sales of Shares is hereinafter referred to as the “Prospectus.” All references in this Agreement to the Registration Statement, the Rule 462(b) Registration Statement, a preliminary prospectus, the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“XXXXX”).

Immediately prior to the purchase of the Shares by the Underwriters on the Closing Date (as defined below):

(i) all of the outstanding shares of the Company’s Series A, Series B, Series C, Series D and Series E convertible preferred stock will be automatically converted into shares of Common Stock, as described in the Prospectus (the “Preferred Stock Conversion”), and

(ii) the Company’s Second Amended and Restated Bylaws will be amended and restated (the “Amendment and Restatement”),

all on terms contemplated by the Prospectus. The Preferred Stock Conversion and the Amendment and Restatement are hereinafter collectively called the “Pre-Closing Transactions.”

7.2 Indemnification by the Underwriters.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, the directors of the Company, the officers of the Company who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) arising out of or based upon any untrue statement or alleged untrue statement of a material

fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus or the Prospectus (as amended or supplemented if the Company shall have furnished any amendments or supplements thereto), or arising out of or based upon 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, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Prospectus or any amendments or supplements thereto.

7.3 Indemnification Procedures.

In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 7 (the “Indemnified Party”), the Indemnified Party shall promptly notify the person against whom such indemnity may be sought (the “Indemnifying Party”) in writing and the Indemnifying Party, shall retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and any others the Indemnifying Party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel, or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Indemnifying Party and the Indemnified Party and representation of both parties by the same counsel would be ethically impermissible due to actual or potential differing interests between them. It is understood that the Indemnifying Party shall not, in respect of the legal expenses of any Indemnified Party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by Xxxxxx Xxxxxx Partners LLC. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The Indemnifying Party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Party agrees to indemnify the Indemnified Party from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnified Party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment includes

an unconditional release of the Indemnified Party from all liability arising out of such action or claim, 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 any Indemnified Party.

7.4 Contribution Agreement.

To the extent the indemnification provided for in this Section 7 is unavailable to an Indemnified Party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Party under such Section 7, in lieu of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Indemnifying Party or Parties, on the one hand, and the Indemnified Party or Parties, on the other hand, from the offering of the Shares or (ii) if the allocation provided by clause 7.4(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 7.4(i) above but also the relative fault of the Indemnifying Party or Parties, on the one hand, and of the Indemnified Party or Parties, on the other hand, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, 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 hand, in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the total public offering price of the Shares. The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, 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 or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 7.4 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. 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 paragraph 7.4, notify such party or parties from whom contribution may be sought, but the omission so to notify such party or parties from whom contribution may be sought shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this paragraph 7.4, except to the extent the party or parties from whom contribution may be sought are actually and adversely prejudiced as a result of the failure to receive notice. No party shall be liable for contribution with respect to any action, suit, proceeding or claim settled without its written consent.

7.5 Contribution Amounts.

The Company and the Underwriters agree that it would not be just or equitable if contribution provided by this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation

that does not take account of the equitable considerations referred to in Section 7.4. The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such 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 remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

7.6 Survival of Provisions.

The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Shares.

8. Effectiveness.

This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9. Termination.

This Agreement shall be subject to termination by notice given by the Representatives to the Company, if (a) after the execution and delivery of this Agreement and prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, or the Nasdaq National Market, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York state authorities or (iv) in the reasonable judgment of the Representatives, there shall have occurred any material adverse change in the financial markets as the result of any outbreak or escalation of hostilities, directly or indirectly, involving the United States or the declaration by the United States of a national emergency or war or any change in financial markets or any calamity or crisis after the date of this Agreement that has an impact on the financial markets, or (v) in the reasonable judgment of the Representatives, there shall have occurred any material adverse change, or any development that could reasonably be expected to result in a material adverse change, in the condition, financial or otherwise, or in the earnings, business, operations or prospects, whether or not arising from transactions in the ordinary course of business, of the

Company and its subsidiaries, taken as a whole, and (b) in the case of any of the events specified in clauses 9(a)(i) through 9(a)(v), such event, individually or together with any other such event, makes it, in the reasonable judgment of the Representatives, impracticable to market the Shares on the terms and in the manner contemplated in the Prospectus.

If this Agreement shall be terminated by the Underwriters, or any of them, pursuant to Sections 9(a)(ii) or 9(a)(v) hereof, or because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such terminating Underwriters in connection with this Agreement and the offering contemplated hereunder.

10. Defaulting Underwriters.

If, on the Closing Date or the Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule A bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased, and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. If, on the Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase Additional Shares or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability to the Company and the non-defaulting Underwriters arising out of or related to any default of such Underwriter under this Agreement.

11. Counterparts.

This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

Re:

Lock-Up Agreement (the “Agreement”)

Ladies and Gentlemen:

The undersigned is an owner of record or beneficially of certain shares of Common Stock, par value $0.001 per share (the “Common Stock”), of Allion Healthcare, Inc., a Delaware corporation (the “Company”), or securities convertible into or exchangeable or exercisable for Common Stock. The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in such agreement (collectively, the “Underwriters”), with the Company providing for a public offering of the Common Stock of the Company pursuant to a Registration Statement on Form S-1 to be filed with the Securities and Exchange Commission (the “Public Offering”). The undersigned recognizes that the Public Offering will be of benefit to the undersigned and will benefit the Company by, among other things, raising additional capital for its operations. The undersigned acknowledges that you and the other Underwriters are relying on the representations and agreements of the undersigned contained in this letter in carrying out the Public Offering and in entering into underwriting arrangements with the Company with respect to the Public Offering.

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Xxxxxx Xxxxxx Partners LLC (which consent may be withheld in its sole discretion), it will not, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock, or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise. The foregoing sentence shall not apply to the exercise of options or warrants or the conversion of a security outstanding on the date of the Prospectus and which is described in the Registration Statement on Form S-1; provided, however, that the undersigned agrees that the foregoing sentence shall apply to any securities issued by the Company to the undersigned upon such an exercise or conversion. The undersigned agrees that if, (1) during the last 17 days of the 180-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs, or (2)

prior to the expiration of the 180-day restricted period, the Company announces that it will release earnings results or becomes aware that material news or a material event will occur during the 16-day period beginning on the last day of the 180-day period, the 180-day period automatically shall extend until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The undersigned hereby acknowledges and agrees that written notice of any extension of the 180-day lock-up period pursuant to the previous paragraph will be delivered by Xxxxxx Xxxxxx Partners LLC to the Company and that any such notice properly delivered will be deemed to have been given to, and received by, the undersigned. The undersigned further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this lock-up agreement during the period from the date of this lock-up agreement to and including the 34^th day following the expiration of the initial 180-day lock-up period, it will give notice thereof to the Company and will not consummate such transaction or take any such action unless it has received written confirmation from the Company that the 180-day lock-up period (as may have been extended pursuant to the previous paragraph) has expired.

The restrictions described above are expressly agreed to preclude the undersigned from engaging in any hedging or other transaction which is designed to or reasonably expected to lead to or result in a sale or disposition of the Common Stock even if such Common Stock would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include, without limitation, any short sale or any purchase, sale or grant of any right (including without limitation any put option or put equivalent position or call option or call equivalent position) with respect to any of the Common Stock or with respect to any security that includes, relates to, or derives any significant part of its value from such Common Stock.

Notwithstanding the foregoing, the undersigned may sell or otherwise transfer shares of Common Stock, without the prior written consent of Xxxxxx Xxxxxx Partners LLC, (1) as a bona fide gift or gifts, (2) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, (3) if the undersigned is a partnership or corporation or similar entity, as a distribution to partners or stockholders of the undersigned, if any, (4) if the undersigned is a corporation, as a transfer to any wholly-owned subsidiary of such corporation, (5) to an entity controlled by the undersigned or an immediate family member of the undersigned, or (6) by will or the laws of descent and distribution; provided, however, that in the case of each such transfer, it shall be a condition to the transfer that (1) the transferee execute an agreement stating that the transferee agrees to be bound by the restrictions contained in this Agreement, (2) any such transfer shall not involve a disposition for value, (3) such transfer is not required to be reported in any public report or filing with the Securities and Exchange Commission or otherwise and (4) the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfers. For purposes of this Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. Furthermore, the undersigned may sell shares of Common Stock of the Company purchased by the undersigned in the open market following the Public Offering.

In addition, the undersigned agrees that, without the prior written consent of Xxxxxx Xxxxxx Partners LLC (which consent may be withheld in its sole discretion) it will not, during the period commencing on the date hereof and ending 180 days after the date of the Prospectus, make any demand for or exercise any right with respect to, the registration under the Securities Act of 1993, as amended, of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock. With respect to the Public Offering, the undersigned waives any registration rights relating to registration under the Securities Act of any Common Stock, or any securities convertible into or exercisable or exchangeable for Common Stock, owned either of record or beneficially by the undersigned, including any rights to receive notice of the Public Offering.

The undersigned understands that whether or not the Public Offering actually occurs depends on a number of factors, including stock market conditions. The Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation among the Company and the Underwriters. If the Public Offering does not close by October 31, 2005, this Agreement shall terminate immediately upon such date and be of no further force and effect.

The undersigned agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of shares of Common Stock or securities convertible into or exchangeable or exercisable for Common Stock held by the undersigned except in compliance with the foregoing restrictions.

This Agreement is irrevocable and will be binding on the undersigned and the respective successors, heirs, personal representatives, and assigns of the undersigned.

This lock-up agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.

Very truly yours,
