Xxxxxx, Xxxxxxxx 00000

Attention:      Mr. Xxxxxxx Xxxxxxxx, Chairman and Chief Executive Officer

Dear Sir:

We understand that Protech Home Medical Corp. ("Protech" or the "Company") intends to issue and sell 21,740,000 units (the "Offered Units"), consisting of one common share in the capital of Protech (a "Common Share"), and one half of one Common Share purchase warrant (each full warrant, a "Warrant") at a price (the "Offer Price") of $1.15 per Offered Unit for aggregate gross proceeds of $25,001,000 (the "Offering"). Each Warrant will entitle the holder thereof to purchase one Common Share (a "Warrant Share") for a period of 12 months after the Closing Date (as defined below) at an exercise price of $1.60.

We also understand that the Company intends to issue and sell, at the option of the Underwriters (as defined below), up to an additional 15% of the Offering (the "Over-Allotment Option") at the Offer Price for additional gross proceeds of up to $3,750,150, for a period of 30 days following the Closing Date upon the terms and conditions set forth herein. The Underwriters may elect to exercise the Over-Allotment Option, in whole or in part, for additional Offered Units only, Common Shares only, or Warrants only, or any combination thereof (collectively, the "Over-Allotment Securities"). The Offered Units and the Over-Allotment Securities are collectively referred to herein as the "Offered Securities".

We also understand that the Company is eligible and prepared to file, concurrently with the execution of this agreement (the "Underwriting Agreement"), a preliminary short form prospectus dated the date hereof (in the English language) (the "Preliminary Prospectus"), and all other necessary documents required to obtain a decision document issued by the BCSC (as defined below), as principal regulator, evidencing that a receipt (or deemed receipt) has been issued for the Preliminary Prospectus in each of the Qualifying Jurisdictions (as defined below). The Underwriters also understand that the Company shall prepare and file within the time limits and on the terms set out below, a (final) short form prospectus (in the English language) (the "Final Prospectus"), and all other necessary documents in order to qualify the Offered Securities for distribution to the public in each of the Qualifying Jurisdictions.

The Offered Securities may be distributed in the Provinces of British Columbia, Alberta and Ontario (and such other provinces as may be agreed between the Company and the Underwriters) by the Underwriters pursuant to the Final Prospectus. Offers and sales of Offered Securities to, or for the account or benefit of, persons in the United States (as defined below) or to, or for the account or benefit of, U.S. Persons (as defined below), may be made by the Underwriters, acting through their U.S. Affiliates (as defined below), in compliance with Schedule "A" hereto, (i) to Qualified Institutional Buyers (as defined below) in accordance with Rule 144A (as defined below) under the U.S. Securities Act (as defined below), and (ii) to Institutional Accredited Investors (as defined below) in accordance with Rule 506(b) of Regulation D under the U.S. Securities Act, and, in each case, in compliance with similar exemptions under applicable state securities laws. With respect to the Offered Securities to be sold to Qualified Institutional Buyers in compliance with Rule 144A, the Underwriters, or their U.S. Affiliates, shall purchase such Offered Securities from the Company for resale in compliance with Rule 144A. Although this Underwriting Agreement is presented on behalf of the Underwriters as purchasers, the Underwriters may arrange for substituted purchasers (the "Substituted Purchasers") for the Offered Securities in connection with private placements of such securities to Institutional Accredited Investors in accordance with Rule 506(b) of Regulation D under the U.S. Securities Act. Each Substituted Purchaser shall purchase Offered Securities directly from the Company at the Offer Price, and to the extent that Substituted Purchasers purchase Offered Securities, the obligations of the Underwriters to do so will be reduced by the number of Offered Securities purchased by the Substituted Purchasers directly from the Company. Any reference in this Underwriting Agreement hereafter to "purchasers" shall be taken to be a reference to the Underwriters, as the initial committed purchasers, and to the Substituted Purchasers, if any. Subject to Applicable Securities Laws (as defined below) and the terms of this Underwriting Agreement, the Offered Securities may also be distributed outside of Canada and the United States in each jurisdiction where they may be lawfully sold by the Underwriters without: (a) giving rise to any requirement under the laws of such jurisdiction to prepare and/or file a prospectus, registration statement or document having similar effect; or (b) creating any ongoing compliance or continuous disclosure obligations for the Company pursuant to the laws of such jurisdiction.

Based upon and subject to the terms and conditions set out below, (a) Beacon Securities Limited and Canaccord Genuity Corp. (as co-lead underwriters, collectively, the "Co-Lead Underwriters") and Echelon Wealth Partners Inc., Xxxxxx Xxxxxxxx Canada Inc., Industrial Alliance Securities Inc. and M Partners Inc. (collectively with the Co-Lead Underwriters, the "Underwriters" and individually an "Underwriter"), hereby severally (and not jointly nor jointly and severally), offer to purchase from the Company in the respective percentages set out in Section 17 of this Underwriting Agreement, and the Company hereby agrees to sell to the Underwriters all, but not less than all, of the Offered Units at the Offer Price per Offered Unit, and (b) in the event and to the extent the Over-Allotment Option granted to the Underwriters pursuant to Section 11 of this Underwriting Agreement is exercised by the Underwriters, the Company agrees to sell to each of the Underwriters, and each of the Underwriters agrees severally (and not jointly nor jointly and severally) to purchase from the Company the respective percentage of the Over-Allotment Securities, as applicable, set forth opposite the name of such Underwriter in Section 17 of this Underwriting Agreement at the applicable offer price per Over-Allotment Security set forth in Section 11.

Concurrent with the Offering, the Company will, on or prior to the Closing Date, enter into subscription agreements pursuant to which certain ‎purchasers will agree to purchase, on a brokered, ‎private placement basis pursuant to exemptions from the prospectus requirements under Canadian Securities Laws and pursuant to the exclusion from registration requirements of the U.S. Securities Act provided by Rule 903 of Regulation S thereunder, an aggregate of up to 1,750,000 additional Offered Units at the ‎Offer Price for aggregate gross proceeds of up to approximately $2,012,500 (the "Concurrent Private Placement"). Subject to obtaining ‎regulatory approval, the closing of the Concurrent Private Placement is expected to occur concurrently with the ‎closing of the Offering.‎ Closing of the Offering is not conditional upon the closing of the Concurrent Private Placement.

In addition, concurrent with the Offering, the Company will, on or prior to the Closing Date, enter into subscription agreements pursuant to which certain persons in the United States or U.S. Persons will agree to purchase, on a non-brokered, private placement basis pursuant to the exemption from the registration requirements of the U.S. Securities Act provided by Rule 506(b) of Regulation D thereunder, an aggregate of up to 927,826 additional Offered Units at the Offer Price for aggregate gross proceeds of up to approximately $1,067,000 (the "Concurrent Non-Brokered Private Placement", and together with the Concurrent Private Placement, the "Private Placements"). Subject to obtaining regulatory approval, the closing of the Concurrent Non-Brokered Private Placement is expected to occur concurrently with the closing of the Offering. Closing of the Offering is not conditional upon the closing of the Concurrent Non-Brokered Private Placement.

The Prospectuses do not qualify any securities issued under the Private Placements. The Offered Units to be issued under the Private Placements will be subject to a statutory hold period ‎lasting four months and one day following the closing of the respective Private Placements. The Company will pay to the Underwriters a cash fee equal to 5.5% of the gross proceeds raised under the Concurrent Private Placement, together with such number of non-transferable compensation options (the "Private Placement Compensation Options") equal to 5.5% of the Offered Units sold pursuant to the Concurrent Private Placement. Each Private Placement Compensation Option is exercisable to acquire one Common Share at the Offer Price at any time prior to 4:00 p.m. (Toronto time) on the date that is two years following the Closing Date.

11. Over-Allotment Option and Over-Allotment Closing

(1) The Company hereby grants to the Underwriters, in the respective percentages set out in Section 17 of this Underwriting Agreement, the Over-Allotment Option to purchase the Over-Allotment Securities at the applicable offer price as follows: (a) units at the Offer Price, with each unit being comprised of one Common Share and one-half of one Warrant; (b) Common Shares at a price of $1.119 per share; (c) Warrants at a price of $0.062 per Warrant; or (d) any combination of units, Common Shares and Warrants, so long as the aggregate number of Common Shares and Warrants that may be issued upon exercise of the Over-Allotment Option does not exceed 3,261,000 Common Shares and 1,630,500 Warrants. The Over-Allotment Option may be exercised, in whole or in part and from time to time, prior to its expiry in accordance with the provisions of this Underwriting Agreement by Beacon delivering to the Company written notice of exercise, setting out the number of units, Common Shares and/or Warrants to be purchased by the Underwriters, which notice must be received by the Company not later than 5:00 p.m. (Toronto time) on the date that is thirty (30) days after the Closing Date. Upon the furnishing of the notice, the Underwriters will severally (and not jointly nor jointly and severally) be committed to purchase in the respective percentages set out in Section 17 of this Underwriting Agreement and the Company will be committed to issue and sell in accordance with and subject to the provisions of this Underwriting Agreement, the number and composition of Over-Allotment Securities indicated in the notice. Over-Allotment Securities may be purchased by the Underwriters only for the purpose of satisfying over-allocations made in connection with the distribution of the Offered Securities and for market stabilization purposes permitted pursuant to Canadian Securities Laws.

(2) In the event that the Over-Allotment Option is exercised by the Underwriters and any of the Over-Allotment Securities are purchased by the Underwriters, the closing shall be held at the offices mentioned in Section 10 above, or at such other place as shall be agreed upon by the Underwriters and the Company, on the Over-Allotment Closing Date.

(3) At the Time of Closing on an Over-Allotment Closing Date, if any, for the exercise of the Over-Allotment Option, subject to the terms and conditions contained in this Underwriting Agreement, the Company shall deliver the Over-Allotment Securities to the Underwriters in the form of certificates representing the Common Shares and the Warrants or in the form of an electronic deposit pursuant to the NCI System maintained by CDS, against payment of the applicable aggregate offer price by wire transfer on such Over-Allotment Closing Date payable to Protech. Protech will, at the Time of Closing on such Over-Allotment Closing Date, and upon such payment of the applicable aggregate offer price to Protech, make payment in full of the Underwriting Fee which shall be made by Protech directing Beacon to withhold the Underwriting Fee from the payment of the applicable aggregate offer price. Certificates, if any, representing the Over-Allotment Securities shall be registered in such names as the Underwriters may request, provided such request is made at least two (2) Business Days prior to the Over-Allotment Closing Date. Any electronic deposit shall be made to such CDS instant deposit numbers as the Co-Lead Underwriters may request, provided that such request is made at least one (1) Business Day prior to the Over-Allotment Closing Date.

(4) The closing of the Over-Allotment Option shall be conditional upon the conditions set forth in Section 6 that apply to an Over-Allotment closing, except that such conditions that apply shall be satisfied as at the Time of Closing on such Over- Allotment Closing Date.

- 40 -

12. Compensation of the Underwriters

Protech shall pay to the Underwriters at the Time of Closing a fee (the "Underwriting Fee") equal to $0.06325 per Offered Security sold pursuant to the terms of this Underwriting Agreement (being 5.5% of the gross proceeds received by the Company from the sale of each of the Offered Securities). The Company acknowledges that the services of the Underwriters are not subject to HST and agrees that, in the event that HST becomes exigible on the Underwriting Fee, the Company shall pay such amount to the Underwriters.

As additional consideration, the Underwriters will also receive non-transferable options (the "Compensation Options") exercisable at any time up to 24 months following the Closing Date to acquire that number of Common Shares (the "Compensation Shares") at the Offer Price in an amount equal to 5.5% of the Offered Securities issued pursuant to the Offering and the exercise of the Over-Allotment Option. Notwithstanding the foregoing and for clarity, no Compensation Options will be issued in connection with any Warrants purchased individually, and not forming part of an Offered Unit, in connection with the Over-Allotment Option. The Underwriting Fee and the Compensation Options will be paid by the Company to the Underwriters on the Closing Date. If the Compensation Options are unavailable for any reason the Company shall pay the Underwriters other compensation of comparable value to the Compensation Options. Such other compensation shall be agreed to between the Company and the Underwriters, each acting reasonably.

13. Termination Rights

(1) In addition to any other remedies which may be available to the Underwriters in respect of any default, act or failure to act, or non-compliance with the terms of this Underwriting Agreement by Protech, any Underwriter shall be entitled, at such Underwriter's option, to terminate and cancel, without any liability on such Underwriter's part, such Underwriter's obligations under this Underwriting Agreement to purchase the Offered Units or the Over-Allotment Securities, at or at any time prior to the applicable Time of Closing if:

(a) (i) any inquiry, action, investigation or other proceeding, whether formal or informal, is commenced, announced, or threatened or any order or ruling is issued by any exchange or market, or any other regulatory authority in Canada or the United States; or (ii) 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 or, is promulgated or changed which inquiry, investigation, proceeding, order, ruling, law or regulation, in the opinion of such Underwriter, acting reasonably, operates to prohibit or materially restrict the distribution or trading of the Offered Securities or which, in the opinion of the Underwriter, acting reasonably, would reasonably be expected to have a significant adverse effect on the market price or value of the Offered Securities; or

(b) there shall occur or come into effect any material change in the business, affairs, financial condition, prospects, capital or control of the Company and its Subsidiaries, taken as a whole or any change in any material fact or a new material fact arises or is discovered that in the opinion of the Underwriter, acting reasonably, has or could reasonably be expected to have a significant adverse effect on the market price or value or marketability of the Offered Securities, Common Shares or other securities of the Company; or

- 41 -

(c) there should develop, occur or come into effect or existence, any event, action, state, condition or major financial occurrence of national or international consequence, including without limiting the generality of the foregoing, any natural disaster, military conflict, civil insurrection, or any terrorist action (whether or not in connection with such conflict or insurrection), pandemic (excluding COVID-19 pandemic except in the event of an unexpected and currently unpredictable material escalation in the severity of the COVID-19 pandemic), which, in the reasonable opinion of such Underwriter, seriously adversely affects or involves, or will seriously adversely affect or involve, the Canadian or United States financial market or the business, operations or affairs of the Company and the Material Subsidiaries taken as a whole or the marketability of the Offered Securities and/or Common Shares; or

(d) an order shall have been made or threatened to cease or suspend trading in the Common Shares or any other securities of the Company, or to otherwise prohibit or restrict in any manner the distribution or trading of the Common Shares or any other securities of the Company, or proceedings are announced or commenced for the making of any such order by any securities regulatory authority or similar regulatory or judicial authority or the TSXV, which order has not been rescinded or withdrawn; or

(e) any condition shall remain outstanding and uncompleted at any time after the time which it is required to be completed or waived, or Protech is in breach of any representation, warranty, condition or covenant of this Underwriting Agreement, including the requirement of the Company to make all necessary filings in any Qualifying Jurisdiction where it is not currently a reporting issuer, but in which the Prospectuses will be filed for purposes of effecting sales under the Offering in such Qualifying Jurisdictions, prior to or concurrently with the filing of the Preliminary Prospectus such that it becomes short form eligible in such Qualifying Jurisdictions.

(2) The rights of termination contained in this section may be exercised by any Underwriter giving written notice thereof to the Company at any time prior to the applicable Time of Closing and are in addition to any other rights or remedies the Underwriters may have in respect of any default, act or failure to act, or non- compliance by the Company in respect of any of the matters contemplated by this Underwriting Agreement or otherwise. In the event of any such termination, there shall be no further liability or obligation on the part of such Underwriter to the Company or on the part of the Company to such Underwriter except in respect of any liability or obligation under any of Section 14, Section 15 and Section 16, which will remain in full force and effect.

14. Indemnity

(1) Protech covenants and agrees to protect, indemnify, and save harmless, each of the Underwriters and their respective U.S. Affiliates, and each of their respective directors, officers, employees, affiliates and agents and each Person, if any, who controls any Underwriter or its U.S. Affiliate (individually, an "Indemnified Party" and, collectively, the "Indemnified Parties"), against all losses (other than loss of profits), claims, damages, suits, liabilities, reasonable costs, or reasonable expenses caused or incurred, whether directly or indirectly, by reason of:

(a) any information or statement (except for information or statements relating solely to the Underwriters and furnished by them in writing specifically for use in the Offering Documents) contained in any of the Offering Documents, or any certificate of Protech delivered hereunder, which at the time and in the light of the circumstances under which it was made contains or is alleged to contain a misrepresentation or any misstatement of a material fact or any omission or alleged omission to state in the Offering Documents any material fact (except for any information and statements relating solely to the Underwriters and furnished by them in writing specifically for use in the Offering Documents) required to be stated in the Offering Documents, or necessary to make any of the statements therein not misleading in light of the circumstances in which they were made;

- 42 -

(b) any order made, or inquiry, investigation or proceeding commenced by any securities regulatory authority or other competent authority based upon any misrepresentation, untrue statement or omission or alleged untrue statement or omission in the Offering Documents (except for information and statements relating solely to the Underwriters and furnished by them in writing specifically for use in the Offering Documents) that prevents or restricts the trading in any of Protech's securities or the distribution or distribution to the public, as the case may be, of any of the Offered Securities in any of the Qualifying Jurisdictions;

(c) Protech not complying with any requirement of Applicable Securities Laws or stock exchange requirements in connection with the transactions herein contemplated, including Protech's non-compliance with any statutory requirement to make any document available for inspection; or

(d) any breach of a representation or warranty of Protech contained in this Underwriting Agreement or the failure of Protech to comply with any of its obligations hereunder;

provided that, if and to the extent that a court of competent jurisdiction in a final judgment from which no appeal can be made determines that such losses, claims, damages, suits, liabilities, costs or expenses resulted from the dishonesty, fraud, negligence, or wilful misconduct of the Indemnified Party claiming indemnity, such Indemnified Party shall promptly reimburse to the Company any funds advanced to the Indemnified Party in respect of such losses, claims, damages, suits, liabilities, costs or expenses and the indemnity provided for in this Section 14 shall cease to apply to such Indemnified Party in respect of such losses, claims, damages, suits, liabilities, costs or expenses; provided that for greater certainty, the foregoing shall not disentitle an Underwriter from indemnification hereunder to the extent that negligence, if any, relates to the Underwriter's failure to conduct adequate "due diligence".

(2) If any Indemnified Party receives actual notice of any formal proceeding commenced against it in a court of competent jurisdiction in respect of which indemnification is or might reasonably be considered to be provided under any of Section 14(1), such Indemnified Party will notify the Company as soon as possible of the nature of such claim; provided, however, that omission to so notify the Company will relieve the Company of any liability that it may otherwise have to the Indemnified Party hereunder, to the extent the defence against such claim is materially prejudiced by such omission, or to the extent that failure to provide notice of such claim results in any material increase in the liability which the Company would otherwise have under Section 14(1) had such Indemnified Party not so delayed in giving or failed to give the notice required under this Section 14(2), and the Company shall be entitled (but not required) to assume the defence of any suit brought to enforce such claim; provided, however, that the defence shall be through legal counsel reasonably acceptable to such Indemnified Party and that no settlement may be made by the Company or such Indemnified Party without the prior written consent of the other, such consent not to be unreasonably withheld or delayed.

(3) In any such claim, such Indemnified Party shall have the right to retain other legal counsel to act on such Indemnified Party's behalf, provided that the reasonable fees and disbursements of such other legal counsel shall be paid by such Indemnified Party, unless: (i) the Company does not promptly assume the defence of the Claim no later than 30 days after receiving actual notice of the Claim, (ii) the Company and such Indemnified Party mutually agree to retain other legal counsel; or (iii) the representation of the Company and such Indemnified Party by the same legal counsel would, in the opinion of such counsel, be inappropriate due to actual or potential differing interests, in which event such fees and disbursements shall be paid by the Company to the extent that they have been reasonably incurred, provided that in no circumstances will the Company be required to pay the fees and expenses of more than one set of legal counsel (and any required local counsel) for all Indemnified Parties.

- 43 -

(4) To the extent that any Indemnified Party is not a party to this Underwriting Agreement, the Underwriters shall obtain and hold the right and benefit of this section in trust for and on behalf of such Indemnified Party.

(5) The Company hereby consents to personal jurisdiction in any court in which any claim that is subject to indemnification hereunder is brought against the Underwriters or any Indemnified Party and to the assignment of the benefit of this section to any Indemnified Party for the purpose of enforcement provided that nothing herein shall limit the Company's right or ability to contest the appropriate jurisdiction or forum for the determination of any such claims.

(6) Except as contemplated in this section, the Company shall not be liable under this section for any settlement of any claim or action effected without its prior written consent, which shall not be unreasonably withheld or delayed.

(7) In no event shall any Indemnified Party have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company or any of its affiliates, security holders or creditors related to, arising out of or in connection with the Underwriters' engagement, performance of any service in connection therewith or any transaction contemplated thereby, other than with respect to any claim that is judicially determined by final non-appealable order issued by a court of competent jurisdiction to have resulted solely from such Indemnified Party's gross negligence or wilful misconduct. Neither party shall be liable to the other for consequential, incidental, indirect, punitive or special damages (including loss of profits, data, business or goodwill), regardless of the legal theory advanced or of any notice given as to the likelihood of such damages; provided that (a) this provision shall not limit an Indemnified Party's indemnity or contribution rights as provided for in this Underwriting Agreement or applicable law and (b) damages required to be paid by an Indemnified Party to any third party that is not an Indemnified Party may be considered direct damages to such Indemnified Party.

(8) The indemnity obligations of the Company hereunder are in addition to rights the Underwriters may have at common law or otherwise and shall inure to the benefit of any successors and permitted assigns of the Company and Indemnified Party.

15. Contribution

In the event that the indemnity provided for in Section 14 is declared by a court of competent jurisdiction to be illegal or unenforceable as being contrary to public policy or for any other reason, the Underwriters and the Company shall contribute to the aggregate of all losses, claims, costs, damages, expenses or liabilities of the nature provided for above such that each Underwriter shall be responsible for that portion represented by the percentage that the portion of the Underwriting Fee payable by Protech to such Underwriter bears to the gross proceeds realized by Protech from the distribution, whether or not the Underwriters have been sued together or separately, and the Company shall be responsible for the balance, provided that in no event shall an Underwriter be responsible for any amount in excess of the portion of the Underwriting Fee actually received by such Underwriter. In the event that the Company may be held to be entitled to contribution from the Underwriters under the provisions of any statute or law, the Company shall be limited to contribution in an amount not exceeding the lesser of: (a) the portion of the full amount of losses, claims, costs, damages, expenses, and liabilities giving rise to such contribution for which such Underwriter is responsible; and (b) the amount of the Underwriting Fee actually received by any Underwriter. Notwithstanding the foregoing, a Person guilty of fraud, negligence, wilful misconduct, illegality or fraudulent misrepresentation shall not be entitled to contribution from any other party. Any party entitled to contribution will, promptly after receiving notice of commencement of any claim, 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, notify such party or parties from whom contribution may be sought, but the omission to so notify such party shall not relieve the party from whom contribution may be sought from any obligation it may have otherwise under this section, except to the extent that the party from whom contribution may be sought is materially prejudiced by such omission. The right to contribution provided herein shall be in addition to and not in derogation of any other right to contribution which the Underwriters may have by statute or otherwise by law.

- 44 -

16. Expenses

Nothing in this Underwriting Agreement is intended to create any relationship in the nature of a partnership or joint venture among the Underwriters.

Except as expressly provided for in this Underwriting Agreement, all warranties, representations, covenants and agreements of Protech and the Underwriters herein contained, or contained in documents submitted or required to be submitted pursuant to this Underwriting Agreement, shall survive the purchase by the Underwriters of the Offered Securities and shall continue in full force and effect, regardless of the closing of the sale of the Offered Securities and regardless of any investigation which may be carried on by the Underwriters or the Company, or on their behalf, until the later of: (i) the second anniversary of the Closing Date; and (ii) the latest date under the Canadian Securities Laws relevant to a purchaser that a purchaser may be entitled to commence an action or exercise a right of rescission with respect to a misrepresentation contained in the Final Prospectus, and neither the Underwriters nor the purchasers may be limited or prejudiced by any investigation made by or on behalf of the Underwriters in connection with the Offering. Without limitation of the foregoing, the provisions contained in this Underwriting Agreement in any way related to the indemnification or the contribution obligations shall survive and continue in full force and effect, indefinitely, subject only to the limitation requirements of applicable law.

21. No Fiduciary Relationship

The Company hereby acknowledges that the Underwriters are acting solely as underwriters in connection with the purchase and sale of the Offered Securities. The Company further acknowledges that the Underwriters are acting pursuant to a contractual relationship created solely by this Underwriting Agreement entered into on an arm's length basis, and in no event do the parties intend that the Underwriters act or be responsible as a fiduciary to the Company, its management, shareholders or creditors or any other Person in connection with any activity that the Underwriters may undertake or have undertaken in furtherance of the purchase and sale of the Offered Securities, either before or after the date hereof. The Underwriters hereby expressly disclaim any fiduciary or similar obligations to the Company, either in connection with the transactions contemplated by this Underwriting Agreement or any matters leading up to such transactions, and the Company hereby confirms its understanding and agreement to that effect. The Company and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to the Company regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Offered Securities, do not constitute advice or recommendations to the Company. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any breach or alleged breach of any fiduciary or similar duty to the Company in connection with the transactions contemplated by this Underwriting Agreement or any matters leading up to such transactions.
