At any particular time, this initial registration statement, in the form then on file with the Commission, including all material then incorporated by reference therein, all information contained in the registration statement (if any) pursuant to Rule 462(b) and then deemed to be a part of the initial registration statement, and all 430A Information and 430C Information, that in any case has not then been superseded or modified, shall be referred to as the “Initial Registration Statement”. The Company may also have filed, or may file with the Commission, a Rule 462(b) registration statement covering the registration of the Offered Securities. At any particular time, this Rule 462(b) registration statement, in the form then on file with the Commission, including the contents of the Initial Registration Statement incorporated by reference therein and including all 430A Information and all 430C Information, that in any case has not then been superseded or modified, shall be referred to as the “Additional Registration Statement”.

As of the time of execution and delivery of this Agreement, the Initial Registration Statement has been declared effective under the Act. Any Additional Registration Statement has or will become effective upon filing with the Commission pursuant to Rule 462(b). The Offered Securities all have been or will be duly registered under the Act pursuant to the Initial Registration Statement and, if applicable, the Additional Registration Statement.

For purposes of this Agreement:

3. Purchase, Sale and Delivery of Offered Securities. On the basis of the representations, warranties and agreements and subject to the terms and conditions set forth herein, each Selling Stockholder agrees, severally and not jointly, to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from each Selling Stockholder, at a purchase price of $24.90 per share, that number of Firm Securities (rounded up or down, as determined by the Underwriters in their discretion, in order to avoid fractions) obtained by multiplying the number of Firm Securities set forth opposite the name of such Selling Stockholder in Schedule A hereto, by a fraction the numerator of which is the number of Firm Securities set forth opposite the name of such Underwriter in Schedule B hereto and the denominator of which is the total number of Firm Securities.

The Custodian and AEA EWT Holdings LP, as applicable, will deliver the Firm Securities to or as instructed by the Underwriters for the accounts of the several Underwriters in a form reasonably acceptable to the Underwriters, against payment of the purchase price by the Underwriters in Federal (same day) funds by wire transfer to the accounts specified by the Custodian and AEA EWT Holdings LP, as applicable, at the office of Xxxxxx & Xxxxxxx LLP, at 9:00 a.m., New York time, on December 4, 2020, or at such other time not later than seven full business days thereafter as the Underwriters and the Company determine, such time being herein referred to as the “First Closing Date”. For purposes of Rule 15c6-1 under the Exchange Act, the First Closing Date (if later than the otherwise applicable settlement date) shall be the settlement date for payment of funds and delivery of securities for all the Offered Securities sold pursuant to the offering. The Custodian and AEA EWT Holdings LP, as applicable, shall deliver the Firm Securities through the facilities of DTC unless the Underwriters shall otherwise instruct. The Custodian and AEA EWT Holdings LP, as applicable, shall deliver the Firm Securities through the facilities of DTC unless the Underwriters shall otherwise instruct.

In addition, upon written notice from the Underwriters given to each of AEA Holdings LP and the Attorneys-in-Fact from time to time not more than 30 days subsequent to the date of the Final Prospectus, the Underwriters may purchase all or less than all of the Optional Securities at the purchase price per share to be paid for the Firm Securities. Following such notice, the Selling Stockholders each agree, severally and not jointly, to sell to the Underwriters and the Underwriters agree, severally and not jointly, to purchase from the Selling Stockholders the respective numbers of Optional Securities obtained by multiplying the number of Optional Securities specified in such notice by a fraction the numerator of which is the number of shares set forth opposite the names of such Selling Stockholders in Schedule A hereto under the caption “Number of Optional Securities to be Sold” and the denominator of which is the total number of Optional Securities (subject to adjustment by the Underwriters to eliminate fractions). Such Optional Securities shall be purchased from each Selling Stockholder for the account of each Underwriter in the same proportion as the number of Firm Securities set forth opposite such Underwriter’s name bears to the total number of Firm Securities (subject to adjustment by the Underwriters to eliminate fractions) and may be purchased by the Underwriters only for the purpose of covering over-allotments made in connection with the sale of the Firm Securities. No Optional Securities shall be sold or delivered unless the Firm Securities previously have been, or simultaneously are, sold and delivered. The right to purchase the Optional Securities or any portion thereof may be exercised from time to time and to the extent not previously exercised may be surrendered and terminated at any time upon notice by the Underwriters to each of AEA Holdings LP and the Attorneys-in-Fact.

Each time for the delivery of and payment for the Optional Securities, being herein referred to as an “Optional Closing Date”, which may be the First Closing Date (the First Closing Date and each Optional Closing Date, if any, being sometimes referred to as a “Closing Date”), shall be determined by the Underwriters but shall be not earlier than two nor later than seven full business days after written notice of election to purchase Optional Securities is given, nor in any event prior to the First Closing Date, unless the Underwriters and the Selling Stockholders agree in writing. The Custodian and AEA EWT Holdings LP, as applicable, will deliver the Optional Securities being purchased on each Optional Closing Date to or as instructed by the Underwriters for the accounts of the several Underwriters, in a form reasonably acceptable to the Underwriters, against payment of the purchase price therefor in Federal (same day) funds by wire transfer to the accounts specified by the Custodian and AEA EWT Holdings LP, as applicable, at the office of Xxxxxx & Xxxxxxx LLP. The Custodian and AEA EWT Holdings LP, as applicable, shall deliver the Optional Securities through the facilities of DTC unless the Underwriters shall otherwise instruct.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Offered Securities for sale to the public as set forth in the Final Prospectus.

5. Certain Agreements of the Company. The Company agrees with the several Underwriters that:

(a) Additional Filings. Unless filed pursuant to Rule 462(c) as part of the Additional Registration Statement in accordance with the second succeeding sentence, the Company will file the Final Prospectus, in a form approved by the Underwriters, which approval shall not be unreasonably withheld, delayed or conditioned, with the Commission pursuant to and in accordance with subparagraph (1) (or, if applicable and if consented to by the Underwriters, subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the second business day following the execution and delivery of this Agreement or (B) the fifteenth business day after the Effective Time of the Initial Registration Statement. The Company will file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the Act) is required in connection with the offering or sale of the Offered Securities. The Company will advise the Underwriters promptly of any such filing pursuant to Rule 424(b) and provide satisfactory evidence to the Underwriters of such timely filing. If an Additional Registration Statement is necessary to register a portion of the Offered Securities under the Act but the Effective Time thereof has not occurred as of the execution and delivery of this Agreement, the Company will file the Additional Registration Statement or, if filed, will file a post-effective amendment thereto with the Commission pursuant to and in accordance with Rule 462(b) on or prior to 10:00 P.M., New York time, on the date of this Agreement or, if earlier, on or prior to the time the Final Prospectus is finalized and distributed to any Underwriter, or will make such filing at such later date as shall have been consented to by the Underwriters.

(b) Filing of Amendments: Response to Commission Requests. The Company will promptly advise the Underwriters of any proposal to amend or supplement at any time the Initial Registration Statement, any Additional Registration Statement or any Statutory Prospectus and will not effect such amendment or supplementation without the Underwriters’ consent, which consent shall not be unreasonably withheld, delayed or conditioned; and the Company will also advise the Underwriters promptly of (i) the effectiveness of any Additional Registration Statement (if its Effective Time is subsequent to the execution and delivery of this Agreement), (ii) any amendment or supplementation of a Registration Statement or any Statutory Prospectus, (iii) any request by the Commission or its staff for any amendment to any Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iv) the institution by the Commission of any stop order proceedings in respect of a Registration Statement or, to the Company’s knowledge, the threatening of any proceeding for that purpose, (v) the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Securities in any jurisdiction or the institution or threatening of any proceedings for such purpose or pursuant to Section 8A of the Securities Act, (vi) any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Act, and (vii) in the event of any such issuance of a notice of objection, promptly to take such steps including, without limitation, amending the Registration Statement or filing a new registration statement, at its own expense, as may be necessary to permit offers and sales of the Offered Securities by the Underwriters (any references herein to the Registration Statement shall include any such amendment or new registration statement). The Company will use its reasonable best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act by any Underwriter or dealer, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the 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 Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Underwriters of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Underwriters and the dealers and any other dealers upon request of the Underwriters, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Underwriters’ consent to, nor the Underwriters’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 8 hereof.

(d) Rule 158. As soon as practicable, but not later than the Availability Date (as defined below), the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the Effective Time of the Initial Registration Statement (or, if later, the Effective Time of the Additional Registration Statement) which will satisfy the provisions of Section 11(a) of the Act (including, at the option of the Company, Rule 158 under the Act). For the purpose of the preceding sentence, “Availability Date” means the day after the end of the fourth fiscal quarter following the fiscal quarter that includes such Effective Time on which the Company is required to file its Form 10-Q for such fiscal quarter except that, if such fourth fiscal quarter is the last quarter of the Company’s fiscal year, “Availability Date” means the day after the end of such fourth fiscal quarter on which the Company is required to file its Form 10-K.

(e) Furnishing of Prospectuses. The Company will furnish to the Underwriters written or electronic copies of each Registration Statement (signed and including all exhibits), each related Statutory Prospectus, and, so long as a prospectus relating to the Offered Securities is (or but for the exemption in Rule 172 would be) required to be delivered under the Act, the Final Prospectus and all amendments and supplements to such documents, in each case in such quantities as the Underwriters may reasonably request. The Final Prospectus shall be so furnished on or prior to the second business day following the execution and delivery of this Agreement. All other such documents shall be so furnished as soon as available. The Company will pay the expenses of printing and distributing to the Underwriters all such documents.

(f) Blue Sky Qualifications. The Company will use its reasonable best efforts, in cooperation with the Underwriters to arrange for the qualification of the Offered Securities for sale under the laws of such jurisdictions as the Underwriters designate and will continue such qualifications in effect so long as required to complete the distribution of the Offered Securities, provided that the Company will not be required to (i) file any general consent to service of process, (ii) qualify as a foreign corporation or other entity or as a dealer in securities in any such jurisdiction in which it is not so already qualified, or (iii) subject itself to taxation in any such jurisdiction in which it is not otherwise subject.

(j) Absence of Manipulation. The Company will not take, directly or indirectly, any action designed to or that would constitute or that would reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Offered Securities.

The Company and Selling Stockholders represent and agree that, unless they obtain the prior consent of the Underwriters, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Underwriters is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

(d) Actions Against Parties; Notification. Promptly after receipt by an indemnified party under this Section 9 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 in writing 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 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, 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 9, as the case may be, 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, 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) Contribution. 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 Stockholders on the one hand and the Underwriters on the other 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 Stockholders on the one hand and the Underwriters on the other 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 Stockholders on the one hand and the Underwriters on the other 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 Stockholders bear to the total compensation received by the Underwriters. 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 Stockholders or the Underwriters 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), (x) no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (y) no Selling Stockholder shall be required to contribute with respect to any losses, claims, damages or liabilities for which such Selling Stockholder would not have been liable under Section 9(b) if such Section 9(b) were applied in accordance with its terms. 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. The Underwriters’ obligations in this subsection (e) to contribute are several in proportion to their respective underwriting obligations and not joint. The Selling Stockholders’ obligations in this subsection (e) to contribute are several in proportion to their respective net proceeds (before deducting expenses) received by the Selling Stockholder from the Offered Securities sold by such Selling Stockholder pursuant to this Agreement and not joint. The Company, the Selling Stockholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9(e) 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 which does not take account of the equitable considerations referred to in this Section 9(e).

(f) Limitation on Liability. In no event shall any Selling Stockholder’s obligations under this Section 9 exceed the net proceeds (before expenses) received by such Selling Stockholder from the sale of its Offered Securities hereunder.

10. [Reserved].

11. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Selling Stockholders, of the Company or its officers and of the several Underwriters 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 any Underwriter, any Selling Stockholder, 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 the purchase of the Offered Securities by the Underwriters is not consummated for any reason, the Company will reimburse the Underwriters for all out of pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities, and the respective obligations of the Company, the Selling Stockholders and the Underwriters pursuant to Section 9 hereof shall remain in effect. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 2 and all obligations under Section 5 shall also remain in effect.

12. Recognition of the U.S. Special Resolutions Regimes.

(a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

17. Absence of Fiduciary Relationship. Each of the Company and the Selling Stockholders acknowledges and agrees that:

(c) Absence of Obligation to Disclose.

18. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company and the Selling Stockholders hereby submit to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

Ladies and Gentlemen:

As an inducement to the Underwriters to execute the Underwriting Agreement (the “Underwriting Agreement”), pursuant to which an offering (the “Offering”) will be made for the common stock, par value $0.01 per share (the “Securities”), of Evoqua Water Technologies Corp., and any successor (by merger or otherwise) thereto, (the “Company”), the undersigned hereby agrees pursuant hereto (the “Lock-Up Agreement”) that during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any Securities or securities convertible into or exchangeable or exercisable for any Securities, whether now owned or hereafter acquired by the undersigned, or with respect to which the undersigned now has or hereafter acquires the power of disposition, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of the Securities, whether any such aforementioned transaction is to be settled by delivery of the Securities or such other securities, in cash or otherwise, or publicly disclose the intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the prior written consent of Citigroup Global Markets Inc. (together, the “Underwriters”). In addition, the undersigned agrees that, without the prior written consent of the Underwriters, it will not, during the Lock-Up Period, make any demand for or exercise any right with respect to, the registration of any Securities or any security convertible into or exercisable or exchangeable for the Securities. To the extent there are no additional Underwriters listed in Schedule B to the Underwriting Agreement other than you, the term “Underwriters” as used herein shall mean Citigroup Global Markets Inc., as Underwriter, and the term Underwriters shall mean the singular as the context requires.

Notwithstanding the foregoing, the undersigned may transfer any Securities or securities convertible into or exchangeable or exercisable for any Securities (i) by will or intestacy, (ii) as a bona fide gift or gifts, (iii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned (for purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, current or former marriage or adoption, not more remote than first cousin), (iv) as a distribution or transfer to general partners, limited partners, members or stockholders of the undersigned, (v) to the undersigned’s subsidiaries, affiliates, or to any investment fund or other entity which controls or manages or is controlled or managed by, or under common control or management with, the undersigned, (vi) pursuant to an order of a court or regulatory agency or by operation of law, such as pursuant to a domestic relations order or in connection with a divorce settlement, (vii) to the Company upon the death, disability or termination of employment, in each case, of the undersigned, (viii) in connection with transactions relating to Securities acquired in open market transactions after the completion of the Offering, (ix) to the Company (a) pursuant to the exercise, in each case on a “cashless” or “net exercise” basis, of any option to purchase Securities granted by the Company pursuant to any employee benefit plans or arrangements described in the General Disclosure Package and the Final Prospectus (each as defined in the Underwriting Agreement), where any Securities received by the undersigned upon any such exercise will be subject to the terms of this Lock-Up Agreement, or (b) for the purpose of satisfying any withholding taxes (including estimated taxes) due as a result of the exercise of any option to purchase Securities or the vesting of any restricted stock or restricted stock unit awards granted by the Company pursuant to employee benefit plans or arrangements described in the General Disclosure Package and the Final Prospectus, in each case on a “cashless,” “net exercise” or “net settlement” basis, where any Securities received by the undersigned upon any such exercise or vesting will be subject to the terms of this Lock-Up Agreement, (x) pursuant to the Offering and/or (xi) with the prior written consent of the Underwriters; provided that in the case of each transfer or distribution pursuant to clauses (ii) through (v) above, the transferee agrees to be bound in writing by the terms of this Lock-Up Agreement prior to such transfer and such transfer shall not involve a disposition for value; provided, further, that in the case of each transfer pursuant to clauses (ii) through (v) and clause (viii) above, no filing or public announcement by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise shall be required or shall be voluntarily made reporting a reduction in beneficial ownership of Securities in connection with such transfer (other than a filing on a Form 5 made after the expiration of the Lock-Up Period), and provided, further, that in the case of each transfer pursuant to clauses (i), (vi), (vii) or (ix) above, if a filing under Section 16 of the Exchange Act is required by, or voluntarily made with respect to, such transfer, the undersigned shall disclose in such filing the reasons for such transfer, unless, in the case of clause (vi), such disclosure would be prohibited by any applicable law, regulation or order of a court or regulatory agency.

Nothing in this Lock-Up Agreement shall prevent (a) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of Securities, provided that such plan (1) does not provide for any transfer of Securities during the Lock-Up Period and (2) is not required to be reported and is not voluntarily disclosed in any public report or filing with the Securities and Exchange Commission or otherwise other than general disclosure in Company periodic reports to the effect that Company directors and officers may, subject to the terms of this Lock-Up Agreement, enter into such trading plans from time to time, or (b) any transactions effectuated pursuant to a Rule 10b5-1 Plan established prior to the date of this Lock-Up Agreement, provided that if a filing under Section 16 of the Exchange Act is required by, or voluntarily made with respect to, such transaction, the undersigned shall disclose in such filing that the transaction was effectuated pursuant to a Rule 10b5-1 Plan.

The undersigned acknowledges and agrees that the underwriters have not provided any recommendation or investment advice nor have the underwriters solicited any action from the undersigned with respect to the offering of the securities and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate.

In furtherance of the foregoing, the Company and its transfer agent and registrar are hereby authorized to decline to make any transfer of shares of Securities if such transfer would constitute a violation or breach of this Lock-Up Agreement.

This Lock-Up Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Lock-Up Agreement shall lapse and become null and void upon the earliest to occur of: (i) the Public Offering Date shall not have occurred on or before December 31, 2020, (ii) prior to the execution of the Underwriting Agreement by the parties thereto, the Company notifies the Underwriters in writing that it does not intend to proceed with the Offering, (iii) for any reason the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Securities to be sold thereunder. This Lock-Up Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

	Very truly yours,
