 Exhibit 10.2 

June 8, 2020 
 Mr. John R. Beaver 

Chief Financial Officer 
 BIOLASE, Inc. 

4 Cromwell 
 Irvine, California, 92618 

Dear Mr. Beaver: 
 This letter (the
“Agreement”) constitutes the agreement between Maxim Group LLC (“Maxim”), The Benchmark Company LLC (“Benchmark”) and Colliers Securities LLC (“Colliers”) (collectively, the
“Placement Agents”) and BIOLASE, Inc., a company incorporated under the laws of the State of Delaware (the “Company”), pursuant to which the Placement Agents shall serve as the placement agents for the Company, on a
“reasonable best efforts” basis, in connection with the proposed placement (the “Placement”) of common stock (the “Shares”) of the Company, par value $0.001 per share (“Common Stock”),
warrants to purchase Common Stock (the “Warrants” and, and collectively with the Shares, the “Securities”). The terms of the Placement and the Securities shall be mutually agreed upon by the Company and the
purchasers (each, a “Purchaser” and collectively, the “Purchasers”) and nothing herein constitutes that the Placement Agents would have the power or authority to bind the Company or any Purchaser or an obligation
for the Company to issue any Securities or complete the Placement. This Agreement and the documents executed and delivered by the Company and the Purchasers in connection with the Placement, including but not limited to the Purchase Agreement (as
defined below), shall be collectively referred to herein as the “Transaction Documents.” The date of the closing of the Placement shall be referred to herein as the “Closing Date.” The Company expressly
acknowledges and agrees that the Placement Agents’ obligations hereunder are on a reasonable best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agents to purchase the Securities
and does not ensure the successful placement of the Securities or any portion thereof or the success of the Placement Agents with respect to securing any other financing on behalf of the Company. Following the prior written consent of the Company,
the Placement Agents may retain other brokers or dealers to act as sub-agents or selected-dealers on its behalf in connection with the Placement. The sale of the Securities to any Purchaser will be evidenced
by a securities purchase agreement (the “Purchase Agreement”) between the Company and such Purchaser in a form mutually agreed upon by the Company and the Placement Agents. Capitalized terms that are not otherwise defined
herein have the meanings given to such terms in the Purchase Agreement. Prior to the signing of any Purchase Agreement, executive officers of the Company will be available upon reasonable notice and during normal business hours to answer inquiries
from prospective Purchasers. 
 SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY; COVENANTS OF THE COMPANY. 

A. Representations of the Company. Each of the representations and warranties (together with any related disclosure schedules thereto)
and covenants made by the Company to the Purchasers in the Purchase Agreement in connection with the Placement is hereby incorporated herein by reference into this Agreement (as though fully restated herein) and is, as of the date of this Agreement
and as of the Closing Date, hereby made to, and in favor of, the Placement Agents. In addition to the foregoing, the Company represents and warrants that: 

1. The Company has prepared and filed with the Commission a registration statement on Form S-3
(Registration No. 333- 233172), and amendments thereto, and related preliminary prospectuses, for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of













 
the Securities, which registration statement, as so amended (including post-effective amendments, if any) became effective on August 23, 2019. At the time of such filing, the Company met the
requirements of Form S-3 under the Securities Act. Such registration statement meets the requirements set forth in Rule 415(a)(1)(x) under the Securities Act and complies with said Rule. The Company will file
with the Commission pursuant to Rule 424(b) under the Securities Act, and the rules and regulations (the “Rules and Regulations”) of the Commission promulgated thereunder, a supplement to the form of prospectus included in such
registration statement relating to the placement of the Shares and the plan of distribution thereof and has advised the Placement Agents of all further information (financial and other) with respect to the Company required to be set forth therein.
Such registration statement, including the exhibits thereto, as amended at the date of this Agreement, is hereinafter called the “Registration Statement”; such prospectus in the form in which it appears in the Registration Statement
is hereinafter called the “Base Prospectus”; and the supplemented form of prospectus, in the form in which it will be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is
hereinafter called the “Prospectus Supplement.” Any reference in this Agreement to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the documents incorporated by
reference therein (the “Incorporated Documents”) pursuant to Item 12 of Form S-3 which were filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
on or before the date of this Agreement, or the issue date of the Base Prospectus or the Prospectus Supplement, as the case may be; and any reference in this Agreement to the terms “amend,” “amendment” or “supplement”
with respect to the Registration Statement, the Base Prospectus or the Prospectus Supplement shall be deemed to refer to and include the filing of any document under the Exchange Act after the date of this Agreement, or the issue date of the Base
Prospectus or the Prospectus Supplement, as the case may be, deemed to be incorporated therein by reference. All references in this Agreement to financial statements and schedules and other information which is “contained,”
“included,” “described,” “referenced,” “set forth” or “stated” in the Registration Statement, the Base Prospectus or the Prospectus Supplement (and all other references of like import) shall be
deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in the Registration Statement, the Base Prospectus or the Prospectus Supplement, as the case may be.
No stop order suspending the effectiveness of the Registration Statement or the use of the Base Prospectus or the Prospectus Supplement has been issued, and no proceeding for any such purpose is pending or has been initiated or, to the
Company’s knowledge, is threatened by the Commission.. 
 2. The Registration Statement (and any further documents to be filed with the
Commission) contains all exhibits and schedules as required by the Securities Act. Each of the Registration Statement and any post-effective amendment thereto, at the time it became effective, complied in all material respects with the Securities
Act and the Exchange Act and the applicable Rules and Regulations and did not and, as amended or supplemented, if applicable, will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. The Base Prospectus, and the Prospectus Supplement, each as of its respective date, comply in all material respects with the Securities Act and the Exchange Act and the applicable Rules and
Regulations. Each of the Base Prospectus, and the Prospectus Supplement, as amended or supplemented, did not and will not contain as of the date thereof any untrue statement of a material fact or omit to state a material fact necessary in order to
make the statements therein, in the light of the circumstances under which they were made, not misleading. The Incorporated Documents, when they were filed with the Commission, conformed in all material respects to the requirements of the Exchange
Act and the applicable Rules and Regulations, and none of such documents, when they were filed with the Commission, contained any untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein (with
respect to Incorporated Documents incorporated by reference in the Base Prospectus or Prospectus Supplement), in the light of the circumstances under which they were made not misleading; and any further documents so filed and incorporated by
reference in the Base Prospectus or Prospectus Supplement, when such documents are filed with the Commission, will conform in all 












 
material respects to the requirements of the Exchange Act and the applicable Rules and Regulations, as applicable, and will not contain any untrue statement of a material fact or omit to state a
material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. No post-effective amendment to the Registration Statement reflecting any facts or events arising after the date
thereof which represent, individually or in the aggregate, a fundamental change in the information set forth therein is required to be filed with the Commission. There are no documents required to be filed with the Commission in connection with the
transaction contemplated hereby that (x) have not been filed as required pursuant to the Securities Act or (y) will not be filed within the requisite time period. There are no contracts or other documents required to be described in the
Base Prospectus, or Prospectus Supplement, or to be filed as exhibits or schedules to the Registration Statement, which (x) have not been described or filed as required or (y) will not be filed within the requisite time period. 

3. [Reserved] 
 4. There are no
affiliations with any FINRA member firm among the Company’s officers, directors or, to the knowledge of the Company, any five percent (5.0%) or greater stockholder of the Company, except as set forth in the Registration Statement and SEC
Reports. 
 B. Covenants of the Company. The Company has delivered or made available, or will as promptly as practicable deliver or
make available, to the Placement Agents complete conformed copies of the Registration Statement and of each consent and certificate of experts, as applicable, filed as a part thereof, and conformed copies of the Registration Statement (without
exhibits), the Base Prospectus, and the Prospectus Supplement, as amended or supplemented, in such quantities and at such places as the Placement Agents reasonably request. Neither the Company nor any of its directors and officers has distributed
and none of them will distribute, prior to the Closing Date, any offering material in connection with the offering and sale of the Securities pursuant to the Placement other than the Base Prospectus, the Prospectus Supplement, the Registration
Statement, copies of the documents incorporated by reference therein and any other materials permitted by the Securities Act. 
 SECTION
2. REPRESENTATIONS OF THE PLACEMENT AGENTS. Each of the Placement Agents, severally and not jointly, represents and warrants that it (i) is a member in good standing of FINRA, (ii) is registered as a broker/dealer under the
Exchange Act, (iii) is licensed as a broker/dealer under the laws of the States applicable to the offers and sales of the Securities by such Placement Agent, (iv) is and will be a corporate entity validly existing under the laws of its
place of incorporation, and (v) has full power and authority to enter into and perform its obligations under this Agreement. Each Placement Agent will immediately notify the Company in writing of any change in its status as such. Each of the
Placement Agents, severally and not jointly, covenants that it will use its reasonable best efforts to conduct the Placement hereunder in compliance with the provisions of this Agreement and the requirements of applicable law.

SECTION 3. COMPENSATION. 

A. In consideration of the services to be provided for hereunder, the Company shall pay to the Placement Agents or their respective designees
on an equal basis, the following compensation: 
 1. A cash fee (the “Cash Fee”) equal to an aggregate of seven percent (7%) of
the aggregate gross proceeds raised in the Placement. The Cash Fee shall be paid to each of the Placement Agents at the Closing of the Placement. 

2. Subject to compliance with FINRA Rule 5110(f)(2)(D), the Company also agrees to reimburse the Placement Agents for all travel and other out-of-pocket expenses, including the reasonable fees, costs and disbursements of its legal counsel, in an amount not to exceed an aggregate of













 
$70,000. The Company will reimburse Placement Agents directly out of the Closing of the Placement. In the event this Agreement shall terminate prior to the consummation of the Placement, the
Placement Agents shall be entitled to reimbursement for actual expenses upon providing reasonable documentation relating to the incurrence of such expenses; provided, however, such expenses shall not exceed $15,000. 

3. Each Placement Agent reserves the right to reduce any item of its compensation or adjust the terms thereof as specified herein in the event
that a determination shall be made by FINRA to the effect that such Placement Agent’s aggregate compensation is in excess of FINRA Rules or that the terms thereof require adjustment. 

SECTION 4. INDEMNIFICATION. The Company agrees to the indemnification and other agreements set forth in the Indemnification
Provisions (the “Indemnification”) attached hereto as Addendum A, the provisions of which are incorporated herein by reference and shall survive the termination or expiration of this Agreement. 

SECTION 5. ENGAGEMENT TERM. The Placement Agents engagement hereunder shall be until the earlier of (i) the final closing
date of the Placement and (ii) the date a party terminates the engagement according to the terms of the next sentence (such date, the “Termination Date” and the period of time during which this Agreement remains in effect is
referred to herein as the “Term”). After an initial period of three (3) month(s) from the date hereof, the engagement may be terminated at any time by either party upon 10 days written notice to the other party, effective upon
receipt of written notice to that effect by the other party. If the Company elects to terminate this Agreement for any reason even though the Placement Agents were prepared to proceed with the Placement reasonably within the intent of this
Agreement, and if within six (6) months following such termination, the Company completes any financing of equity, equity-linked or debt or other capital raising activity of the Company (other than the exercise by any person or entity of any
options, warrants or other convertible securities) with any of the investors contacted by Placement Agents during the term of this Agreement and set forth on a list provided to the Company as of the termination date of this Agreement,, then the
Company will pay the Placement Agents upon the closing of such financing the compensation set forth in Section 3 herein. Notwithstanding anything to the contrary contained herein, the provisions concerning the Company’s obligation to pay
any fees actually earned pursuant to Section 3 hereof and the provisions concerning confidentiality, indemnification and contribution contained herein and the Company’s obligations contained in the Indemnification Provisions will survive
any expiration or termination of this Agreement. If this Agreement is terminated prior to the completion of the Placement, all fees due to the Placement Agents shall be paid by the Company to the Placement Agents on or before the Termination Date
(in the event such fees are earned or owed as of the Termination Date). The Placement Agents agree, severally and not jointly, not to use any confidential information concerning the Company provided to the Placement Agents by the Company for any
purposes other than those contemplated under this Agreement. 
 SECTION 6. PLACEMENT AGENT INFORMATION. The Company agrees
that any information or advice rendered by the Placement Agents in connection with this engagement is for the confidential use of the Company only in their evaluation of the Placement and, except as otherwise required by law, the Company will not
disclose or otherwise refer to the advice or information in any manner without the Placement Agents’ prior written consent. 

SECTION 7. NO FIDUCIARY RELATIONSHIP. This Agreement does not create, and shall not be construed as creating rights enforceable
by any person or entity not a party hereto, except those entitled hereto by virtue of the Indemnification Provisions hereof. The Company acknowledges and agrees that each Placement Agent is not and shall not be construed as a fiduciary of the
Company and shall have no duties or liabilities to the equity holders or the creditors of the Company or any other person by virtue of this Agreement or the retention of such Placement Agent hereunder, all of which are hereby expressly waived. 












 SECTION 8. CLOSING. The obligations of the Placement Agents, and the closing
of the sale of the Securities hereunder are subject to the accuracy, when made and on the Closing Date, of the representations and warranties on the part of the Company contained herein and in the Purchase Agreement, to the accuracy of the
statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of their obligations hereunder, and to each of the following additional terms and conditions, except as otherwise disclosed to
and acknowledged and waived by the Placement Agent by the Company: 
 A. No stop order suspending the effectiveness of the Registration
Statement shall have been issued and no proceedings for that purpose shall have been initiated or threatened by the Commission, and any request for additional information on the part of the Commission (to be included in the Registration Statement,

filed with the Commission. 
 B. The Placement Agents shall not have discovered and disclosed to the Company on or prior to the Closing Date
that the Registration Statement, the Base Prospectus, the Prospectus Supplement or any amendment or supplement thereto contains an untrue statement of a fact which, in the opinion of counsel for the Placement Agents, is material or omits to state
any fact which, in the opinion of such counsel, is material and is required to be stated therein or is necessary to make the statements therein not misleading. 

C. All corporate proceedings and other legal matters incident to the authorization, form, execution, delivery and validity of each of this
Agreement, the Securities, the Registration Statement, the Base Prospectus and the Prospectus Supplement and all other legal matters relating to this Agreement and the transactions contemplated hereby shall be reasonably satisfactory in all material
respects to counsel for Maxim, and the Company shall have furnished to such counsel all documents and information that they may reasonably request to enable them to pass upon such matters. 

D. The Placement Agents shall have received from outside counsels to the Company such counsels’ written opinions, addressed to the
Placement Agents and the Purchasers and dated as of the Closing Date, in form and substance reasonably satisfactory to counsel for Maxim, including but not limited to: (i) an opinion of Loeb & Loeb, LLP, counsel to the Company with
respect to certain corporate and securities matters and (ii) an opinion of Greenberg Traurig, LLP, counsel to the Company with respect to certain intellectual property matters. 

E. On the Closing Date, Placement Agents shall have received a certificate of the Chief Executive Officer of the Company, dated, as applicable,

executive officer of the Company, dated, as applicable, as of the date of such Closing, to the effect that, as of the date of this Agreement and as of the applicable date, the representations and warranties of the Company contained herein and in the
Purchase Agreement were and are accurate in all material respects, except for such changes as are contemplated by this Agreement and except as to representations and warranties that were expressly limited to a state of facts existing at a time prior

I. The Company (i) shall not have sustained since the date of the latest audited financial statements included or incorporated by
reference in the Registration Statement, the Base Prospectus and the Prospectus Supplement, any loss or interference with its business from fire, explosion, flood, terrorist act or other calamity, whether or not covered by insurance, or from any

any development involving a prospective change, in or affecting the business, general affairs, management, financial position, stockholders’ equity, results of operations or prospects of the Company, otherwise than as set forth in or
contemplated by the Registration Statement, the Base Prospectus and the Prospectus Supplement, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Placement Agent, so material and adverse as to make

J. The Common Stock is registered under the Exchange Act and, as of the Closing Date, the Shares shall be listed for trading on the Trading

arrangements of this Agreement. In addition, the Company shall, if requested by the Placement Agents, make or authorize Placement Agents’ counsel to make on the Company’s behalf, any filing with the FINRA Corporate Financing Department
pursuant to FINRA Rule 5110 with respect to the Placement and pay all filing fees required in connection therewith. 
 O. Prior to the
Closing Date, the Company shall have furnished to the Placement Agents such further information, certificates and documents as the Placement Agents may reasonably request. 

If any of the conditions specified in this Section 8 shall not have been fulfilled when and as required by this Agreement, or if any of
the certificates, opinions, written statements or letters furnished to the Placement Agents or to Placement Agents’ counsel pursuant to this Section 8 shall not be reasonably satisfactory in form and substance to the Placement Agents and
to Placement Agents’ counsel, all obligations of the Placement Agents hereunder may be cancelled by the Placement Agents at, or at any time prior to, the consummation of the Closing. Notice of such cancellation shall be given to the Company in
writing or orally. Any such oral notice shall be confirmed promptly thereafter in writing.

underwriter or manager for any and all future public and private equity, equity-linked, debt offerings or other capital raising activity of the Company (other than the exercise by any person or entity of any options, warrants or other convertible
securities), or any successor to or any subsidiary of the Company. 
 SECTION 10. GOVERNING LAW. This Agreement will be
governed by, and construed in accordance with, the laws of the State of New York applicable to agreements made and to be performed entirely in such State. This Agreement may not be assigned by either party without the prior written consent of the
other party. This Agreement shall be binding upon and inure to the benefit of the parties hereto, and their respective successors and permitted assigns. Any right to trial by jury with respect to any dispute arising under this Agreement or any
transaction or conduct in connection herewith is waived. Any dispute arising under this Agreement may be brought into the courts of the State of New York or into the Federal Court located in New York, New York and, by execution and delivery of this
Agreement, the Company hereby accepts for itself and in respect of its property, generally and unconditionally, the jurisdiction of aforesaid courts. Each party hereto hereby irrevocably waives personal service of process and consents to process
being served in any such suit, action or proceeding by delivering a copy thereof via overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. If either party shall commence an action or proceeding to
enforce any provisions of a Transaction Document, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its attorney’s fees and other costs and expenses incurred with the investigation, preparation
and prosecution of such action or proceeding. 
 SECTION 11. ENTIRE AGREEMENT/MISC. This Agreement (including the attached
Indemnification Provisions) embodies the entire agreement and understanding between the parties hereto, and supersedes all prior agreements and understandings, relating to the subject matter hereof. If any provision of this Agreement is determined
to be invalid or unenforceable in any respect, such determination will not affect such provision in any other respect or any other provision of this Agreement, which will remain in full force and effect. This Agreement may not be amended or
otherwise modified or waived except by an instrument in writing signed by all Placement Agents and the Company. The representations, warranties, agreements and covenants contained herein shall survive the closing of the Placement and delivery of the
Securities. This Agreement may be executed in two or more counterparts, all of which when 












 
taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood
that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or a .pdf format file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf
such signature is executed) with the same force and effect as if such facsimile or .pdf signature page were an original thereof. 

SECTION 12. CONFIDENTIALITY. Each of the Placement Agents, severally and not jointly, (i) will keep the Confidential
Information (as such term is defined below) confidential and will not (except as required by applicable law or stock exchange requirement, regulation or legal process (“Legal Requirement”)), without the Company’s prior written
consent, disclose to any person any Confidential Information, and (ii) will not use any Confidential Information other than in connection with the Placement. The Placement Agents further agree, severally and not jointly, to disclose the
Confidential Information only to its Representatives (as such term is defined below) who need to know the Confidential Information for the purpose of the Placement, and who are informed by the Placement Agents of the confidential nature of the
Confidential Information. The term “Confidential Information” shall mean, all confidential, proprietary and non-public information (whether written, oral or electronic communications)
furnished by the Company to a Placement Agent or its Representatives in connection with such Placement Agent’s evaluation of the Placement. The term “Confidential Information” will not, however, include information which
(i) is or becomes publicly available other than as a result of a disclosure by a Placement Agent or its Representatives in violation of this Agreement, (ii) is or becomes available to a Placement Agent or any of its Representatives on a non-confidential basis from a third-party, (iii) is known to a Placement Agent or any of its Representatives prior to disclosure by the Company or any of its Representatives, or (iv) is or has been
independently developed by a Placement Agent and/or the Representatives without use of any Confidential Information furnished to it by the Company. The term “Representatives” shall mean each Placement Agent’s directors, board
committees, officers, employees, financial advisors, attorneys and accountants. This provision shall be in full force until the earlier of (a) the date that the Confidential Information ceases to be confidential and (b) two years from the
date hereof. Notwithstanding any of the foregoing, in the event that a Placement Agent or any of its Representatives are required by Legal Requirement to disclose any of the Confidential Information, such Placement Agent and its Representatives will
furnish only that portion of the Confidential Information which such Placement Agent or its Representative, as applicable, is required to disclose by Legal Requirement as advised by counsel, and will use reasonable efforts to obtain reliable
assurance that confidential treatment will be accorded the Confidential Information so disclosed. 
 SECTION 13.
NOTICES. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of (a) the date of transmission, if such
notice or communication is sent to the email address specified on the signature pages attached hereto prior to 6:30 p.m. (New York City time) on a business day, (b) the next business day after the date of transmission, if such notice or
communication is sent to the email address on the signature pages attached hereto on a day that is not a business day or later than 6:30 p.m. (New York City time) on any business day, (c) the third business day following the date of mailing, if
sent by U.S. internationally recognized air courier service, or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications shall be as set forth on the signature pages
hereto. 
 SECTION 14. PRESS ANNOUNCEMENTS. The Company agrees that the Placement Agents shall, from and after any Closing,

each case at its own expense.

 ADDENDUM A 

INDEMNIFICATION PROVISIONS 

In connection with the engagement of Maxim Group LLC, The Benchmark Company LLC, Colliers Securities, LLC (the “Lead Managers”) by
BIOLASE, Inc. (the “Company”) pursuant to a placement agency agreement dated as of the date hereof, between the Company and the Lead Managers, as it may be amended from time to time in writing (the “Agreement”), the Company
hereby agrees as follows: 
 1. To the extent permitted by law, the Company will indemnify the Lead Managers and each of their respective
affiliates, directors, officers, employees and controlling persons (within the meaning of Section 15 of the Securities Act of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934) against all losses, claims, damages,
expenses and liabilities, as the same are incurred (including the reasonable fees and expenses of counsel), relating to or arising out of its activities hereunder or pursuant to the Agreement, except, with regard to the Lead Managers, to the extent
that any losses, claims, damages, expenses or liabilities (or actions in respect thereof) are found in a final judgment (not subject to appeal) by a court of law to have resulted primarily and directly from the willful misconduct or gross negligence
in performing the services described herein, as the case may be of any or all of the Lead Managers 
 2. Promptly after receipt by the Lead
Managers of notice of any claim or the commencement of any action or proceeding with respect to which the Lead Managers are entitled to indemnity hereunder, the Lead Managers will notify the Company in writing of such claim or of the commencement of
such action or proceeding, and the Company will assume the defense of such action or proceeding and will employ counsel reasonably satisfactory to the Lead Managers and will pay the reasonable fees and expenses of such counsel. Notwithstanding the
preceding sentence, the Lead Managers will be entitled to employ counsel separate from counsel for the Company and from any other party in such action if counsel for the Lead Managers reasonably determines that it would be inappropriate under the
applicable rules of professional responsibility for the same counsel to represent both the Company and the Lead Managers. In such event, the reasonable fees and disbursements of no more than one such separate counsel will be paid by the Company. The
Company will have the exclusive right to settle the claim or proceeding provided that the Company will not settle any such claim, action or proceeding without the prior written consent of the Lead Managers, which will not be unreasonably withheld.

 3. The Company agrees to notify the Lead Managers promptly of the assertion against it or any other person of any claim or the
commencement of any action or proceeding relating to a transaction contemplated by the Agreement. 
 4. If for any reason the foregoing
indemnity is unavailable to the Lead Managers or insufficient to hold the Lead Managers harmless, then the Company shall contribute to the amount paid or payable by the Lead Managers, as the case may be, as a result of such losses, claims, damages
or liabilities in such proportion as is appropriate to reflect not only the relative benefits received by the Company on the one hand, and the Lead Managers on the other, but also the relative fault of the Company on the one hand and the Lead
Managers on the other that resulted in such losses, claims, damages or liabilities, as well as any relevant equitable considerations. The amounts paid or payable by a party in respect of losses, claims, damages and liabilities referred to above
shall be deemed to include any legal or other fees and expenses incurred in defending any litigation, proceeding or other action or claim. Notwithstanding the provisions hereof, the Lead Managers’ share of the liability hereunder shall not be
in excess of the amount of fees actually received, or to be received, by the Lead Managers under the Agreement (excluding any amounts received as reimbursement of expenses incurred by the Lead Managers). 












 5. These Indemnification Provisions shall remain in full force and effect whether or not the
transaction contemplated by the Agreement is completed and shall survive the termination of the Agreement, and shall be in addition to any liability that the Company might otherwise have to any indemnified party under the Agreement or otherwise.
