Exhibit 10.37

SHARE PURCHASE AGREEMENT

This SHARE PURCHASE AGREEMENT (this “Agreement”) is entered into as of November 15, 2017 (the “Effective Date”), by and between New Enterprise Associates 16, L.P., a Delaware limited partnership (the “Investor”), and Arsanis, Inc., a Delaware corporation (the “Company”).

WHEREAS, the Company is proposing to issue and sell to the Investor (the “Offering”) $20,000,000 of the Company’s common stock, $0.001 par value per share (the “Common Stock”), in connection with the Company’s initial public offering of Common Stock (“IPO”), pursuant to the terms and subject to the conditions set forth in this Agreement; 

WHEREAS, the parties hereto have executed this Agreement on the Effective Date, which is prior to the effectiveness of the registration statement on Form S-1 filed by the Company with the Securities and Exchange Commission (the “SEC”) for the Company’s IPO; 

WHEREAS, the closing of the Offering shall take place concurrently with the closing of the IPO and at a price per share equal to the initial public offering price per share that the Common Stock is sold to the public in the IPO, provided, however, that such initial public offering price per share shall not exceed $10.00 per share (the “IPO Price” and such time, the “IPO Closing Time”), as set forth on the cover of the final prospectus filed with the SEC;

WHEREAS, the Shares are being offered to the Investor pursuant to a private placement exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”); and 

WHEREAS, in order to effect the IPO, the Company shall enter into an Underwriting Agreement (the “Underwriting Agreement”) with Citigroup Global Markets Inc., Cowen and Company, LLC and Piper Jaffray & Co., as representative of the several underwriters named therein (the “Underwriters”), substantially in the form attached hereto as Exhibit A;

NOW, THEREFORE, in consideration of the foregoing and the mutual promises and covenants set forth below, the parties hereto hereby agree as follows:

1. Sale of Shares.

(a)  Purchase and Sale. Subject to the terms and conditions set forth in this Agreement, the Company hereby agrees to sell to the Investor, and the Investor hereby agrees to purchase from the Company, $20,000,000 of the Company’s Common Stock (the “Investment Amount”) at the IPO Price. The number of shares of Common Stock to be sold by the Company and purchased by the Investor hereunder (the “Shares”) shall equal the number of shares determined by dividing the Investment Amount by the IPO Price (rounded down to the nearest whole share). The total purchase price to be paid by the Investor for the Shares is equal to (i) the number of Shares multiplied by (ii) the IPO Price (the “Purchase Price”).

 

 

(b) Closing. The closing of the purchase and sale of the Shares (the “Closing”) shall take place at the offices of Davis Polk & Wardwell LLP, 450 Lexington Avenue, New York, New York 10017, or at such other place as shall be agreed upon by the parties hereto, after the satisfaction or waiver of each of the conditions set forth in Section 4 (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the fulfillment or waiver of those conditions) concurrently with the IPO Closing Time. At the Closing, (i) the Company shall cause the Company’s transfer agent to deliver the Shares to the Investor registered in the name of the Investor, and (ii) the Purchase Price for the Shares shall be delivered by or on behalf of the Investor to the Company.

(c) Payment of Purchase Price. Payment by the Investor of the Purchase Price to the Company shall be made at the Closing by wire transfer of immediately available funds equal to the aggregate purchase price for the Shares to an account specified in writing by the Company.

Payment of the Purchase Price for the Shares shall be made against delivery to the Investor of the Shares, which Shares shall be uncertificated and shall be registered in the name of the Investor on the books of the Company by the Company’s transfer agent.

2. Representations and Warranties.

2.1 Representations and Warranties of the Company. The Company represents and warrants to the Investor as follows:

(a) The representations and warranties of the Company set forth in the Underwriting Agreement are true and correct on and as of the date hereof, with the same effect as if made herein on the date hereof (except to the extent any such representations and warranties expressly relate to a particular date, in which case such representations and warranties are true and correct as of such particular date) (after giving effect to any materiality or other qualifiers contained therein); 

(b) The Company has the full right, power, authority and capacity to enter into this Agreement and to consummate the transactions contemplated hereby and has taken all necessary action to authorize the execution, delivery and performance of this Agreement; 

(c) This Agreement constitutes the valid and legally binding obligation of the Company, enforceable in accordance with its terms, subject to bankruptcy, reorganization, insolvency and other similar laws affecting the enforcement of creditors’ rights generally and to general principles of equity. Upon issuance in accordance with, and payment pursuant to, the terms of this Agreement, the Shares will be duly authorized, validly issued and fully-paid and nonassessable;

(d) The execution and delivery by the Company of, and the performance by the Company of its obligations under this Agreement, the issuance, sale and delivery of the Shares, the consummation of the transactions contemplated herein and compliance by the Company with its obligations hereunder does not and will not contravene any provision of applicable law, or the certificate of incorporation or by laws or other organizational documents of the Company, or any 

 

 

agreement or other instrument binding upon the Company or the Shares or any judgment, order or decree of any governmental body, agency or court having jurisdiction over the Company, and no consent, approval, authorization or order of, or qualification with, any governmental body or agency is required for the performance by the Company of its obligations under this Agreement, except, in each case, where any such contravention or where the failure to obtain any such consent, approval, authorization or order would not reasonably be expected to have a material adverse effect on the consummation of the transactions contemplated hereby;

(e) To the knowledge of the Company, the Company has not taken any action which could reasonably be expected to cause the sale of the Shares to be sold by the Company to the Investor to fail to qualify as exempt from the registration requirements of the Securities Act; and

(f) None of the Company, any predecessor of the Company, any affiliated issuer, any director, executive officer, other officer of the Company participating in the Offering, general partner or managing member of the Company, any beneficial owner of 20% or more of the Company’s outstanding voting equity securities, any promoter connected with the Company at the time of any sale of the Shares or any investment manager of the Company (if the Company is a pooled investment fund), as applicable, is subject to the “bad actor” disqualifications set forth in Rule 506(d)(1) of the Securities Act.

2.2 Representations and Warranties of the Investor. The Investor represents and

warrants to the Company as follows: 

(a) (i) It is an institutional “accredited investor” as defined in Rule 501(a) promulgated under the Securities Act; (ii) it has sufficient knowledge and experience in investing in companies similar to the Company so as to be able to evaluate the risks and merits of its investment in the Company and it is able financially to bear the risks thereof; (iii) it has had an opportunity to discuss the Company’s business, management and financial affairs with the Company’s management; (iv) all documents, records, and information pertaining to its investment in the Common Stock and the Company that have been requested by it, if any, have been made available or delivered to it prior to the date hereof; (v) its financial condition is such that it is able to bear the risk of holding the Shares for an indefinite period of time and can bear the loss of the entire investment in such Shares; and (vi) it is not purchasing the Shares as the result of any form of general solicitation or general advertising within the meaning of Rule 502(c) under the Securities Act or as a result of the Investor's review of public filings by the Company;

(b) The Investor understands that this Agreement is made in reliance upon the Investor’s express representations, which it hereby represents and warrants to the Company, that (i) the Shares being purchased by the Investor are being acquired for the Investor’s own account (and not on behalf of any other person or entity) for the purpose of investment and not with a view to, or for sale in connection with, the distribution thereof, nor with any present intention of distributing or selling the Shares or any portion thereof, (ii) the Investor was not organized for the specific purpose of acquiring the Shares and (iii) the Shares will not be sold by the Investor without registration under the Securities Act or applicable state securities laws, or an exemption therefrom;

 

 

(c) The Investor further understands that the Shares being purchased by the Investor hereunder have not been registered under the Securities Act or any state securities laws and are instead being offered and sold in reliance on an exemption from such registration requirements. The Investor represents and warrants to the Company that, to the Investor’s knowledge, the Investor has not taken any action which could reasonably be expected to cause the sale of the Shares to be sold by the Company to the Investor to fail to qualify as exempt from the registration requirements of the Securities Act. The Investor further understands that until such time as the Shares shall have been registered under the Securities Act and applicable state securities laws or shall have been transferred in accordance with an opinion of counsel reasonably satisfactory to the Company that such registration is not required, stop transfer instructions shall be issued to the Company’s transfer agent and any certificate or certificates representing such securities shall bear a restrictive legend stating that such securities have not been registered under the Securities Act and applicable state securities laws and referring to restrictions on the transferability and sale thereof. 

(d) The Investor further understands that its representations and warranties hereunder will not preclude disposition of the Shares without registration thereof, in compliance with Rule 144 promulgated under the Securities Act (“Rule 144”). The Investor understands and acknowledges, however, that there may not be available when the Investor wishes to sell the Shares, or any portion thereof, the adequate current public information with respect to the Company which would permit offers or sales of such securities pursuant to Rule 144, and, therefore, compliance with the Securities Act or some other exemption from the registration and prospectus delivery requirements of the Securities Act may be required for any such offer or sale; and

(e) (i) The Investor is validly existing as a limited partnership in good standing under the laws of the State of Delaware; (ii) the Investor has all requisite power and authority to execute and deliver this Agreement; and (iii) this Agreement constitutes the valid and legally binding obligation of the Investor, enforceable against the Investor in accordance with its terms, subject to bankruptcy, reorganization, insolvency and other similar laws affecting the enforcement of creditors’ rights generally and to general principles of equity.

 

 

4. Conditions to the Closing. The obligations of the Company and the Investor hereunder are subject to the satisfaction of the conditions set forth below on or before the Closing. If for any reason any of the conditions set forth in this Section ‎4 are not satisfied or waived by each party entitled to the benefit of such conditions at or prior to the Closing, then each party by written notice given to the other parties hereto shall have the right to elect to terminate this Agreement and each party shall be released from their obligations hereunder and shall have no further liability hereunder, provided, however, that nothing contained in this Section ‎4 shall relieve either party from liabilities or damages arising out of any fraud or willful breach by such party of this Agreement prior to such termination. 

(a) Conditions to the Investor’s Obligations. The Investor’s obligation to purchase the Shares at the Closing is subject to the satisfaction of the following conditions: 

(i) delivery of an opinion of counsel to the Company, dated the date of the Closing, substantially in the form attached hereto as Exhibit B; 

(ii) the representations and warranties of the Company contained in Section 2.1 shall be true and accurate on and as of the Closing with the same force and effect as if they had been made at the Closing (except to the extent any such representations and warranties expressly relate to a particular date, in which case such representations and warranties are true and correct as of such particular date) (after giving effect to any materiality or other qualifiers contained therein); and

(iii) the Shares shall have been delivered to the Investor’s account.

(b) Conditions to the Company’s Obligations. The Company's obligation to sell the Shares at the Closing is subject to the satisfaction of the following conditions:

(ii) the representations and warranties of the Investor contained in Section 2.2 shall be true and accurate on and as of the Closing with the same force and effect as if they had been made at the Closing; and

(iii) the Underwriters shall have purchased, concurrent with the purchase of the Shares by the Investor hereunder, the Firm Shares (as defined in the Underwriting Agreement) at the IPO Price (less any underwriting discounts or commissions).

5. Registration Rights.

(a) Defined Terms. As used in this Section 5, the following terms shall have the following meanings:

(i) “Prospectus” means (x) the prospectus included in any Registration Statement contemplated by this Section 5, as amended or supplemented by any prospectus 

 

 

supplement, with respect to the terms of the offering of any portion of the Registrable Securities covered by such Registration Statement and by all other amendments and supplements to the prospectus, including post-effective amendments and all material incorporated by reference in such prospectus, and (y) any “free writing prospectus” as defined in Rule 405 promulgated under the Securities Act. 

(ii) “Registrable Securities” means (x) the Shares, and (y) any shares of Common Stock issued or issuable with respect to the Shares by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization. As to any particular Registrable Securities, such securities shall cease to be Registrable Securities when (i) a Registration Statement covering such securities has been declared effective by the SEC and such securities have been disposed of pursuant to such effective Registration Statement, (ii) such securities are sold under circumstances in which all of the applicable conditions of Rule 144 (or any similar provisions then in force) are met, (iii) such securities are otherwise transferred and such securities may be resold without subsequent registration under the Securities Act, or (iv) such securities shall have ceased to be outstanding.

(iii) “Registration Statement” means any registration statement of the Company which covers any of the Registrable Securities pursuant to the provisions of this Section 5, including the Prospectus, amendments and supplements to such Registration Statement, including post-effective amendments, all exhibits and all materials incorporated by reference in such Registration Statement.

(b) Demand Registration.

(i) At any time after the date that is 180 days after the Closing, the Investor may request registration under the Securities Act of all of its Registrable Securities then held on a Form S-1 or Form S-3 registration statement (or any successor to each such form) (or, if Form S-1 or Form S-3 is not then available, on such form of registration statement as is then available to effect a registration of the Registrable Securities pursuant to this subsection (b)(i)) (each a “Demand Registration”). Each request for a Demand Registration shall specify the approximate number of Registrable Securities required to be registered. Upon receipt of a Demand Registration request, the Company shall cause a Registration Statement to be filed within forty-five (45) days after the date on which such request was received by the Company. The Company shall not be required to effect a Demand Registration (A) more than two (2) times for the Investor; provided, however, that a Registration Statement shall not count as a Demand Registration requested under this subsection (b)(i)(A) unless and until it has become effective, or (B) if the Company furnishes to the Investor a certificate signed by an authorized officer of the Company stating that (a) within sixty (60) days of receipt of the Demand Registration request under this subsection (b)(i), the Company expects to file a registration statement for the public offering of securities for the account of the Company (other than a registration of securities (x) issuable pursuant to an employee stock option, stock purchase or similar plan, (y) issuable pursuant to a merger, exchange offer or a transaction of the type 

 

 

specified in Rule 145(a) under the Securities Act or (z) in which the only securities being registered are securities issuable upon conversion of debt securities which are also being registered), provided, that the Company is actively employing good faith efforts to cause such registration statement to become effective, or (b) the Company is engaged in a material transaction or has an undisclosed material corporate development, in either case, which would be required to be disclosed in the Registration Statement, and in the good faith judgment of the Company’s Board of Directors, such disclosure would be materially detrimental to the Company and its stockholders at such time (in which case, the Company shall disclose the matter as promptly as reasonably practicable and thereafter file the Registration Statement, and the Investor agrees not to disclose any information about such material transaction to third parties until such disclosure has occurred or such information has entered the public domain other than through breach of this provision by such Investor), provided, however, that the Company shall have the right to defer the filing of the Registration Statement pursuant to this subsection twice in any twelve (12) month period and any such deferral may not exceed a period of more than sixty (60) days in the aggregate during such twelve-month period.

(ii) If the Investor requests a Demand Registration and elects to distribute the Registrable Securities covered by its request in an underwritten offering, the Investor shall so advise the Company as a part of its request made pursuant to subsection (b)(i). The Company shall select the investment banking firm or firms to act as the managing underwriter or underwriters in connection with such offering; provided, however, that such selection shall be subject to the consent of the Investor, which consent shall not be unreasonably withheld, delayed or conditioned.

(c) Requirements of the Company. 

(i) In connection with the filing by the Company of any Registration Statement, the Company shall furnish to the Investor (x) a copy of the Prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and (y) such other documents as the Investor may reasonably request, in order to facilitate the public sale or other disposition of the Registrable Securities.

(ii) The Company shall use its reasonable best efforts to cause each Registration Statement contemplated by this Section 5 to be declared effective or become effective as soon as practicable following the filing thereof with the SEC. The Company shall notify the Investor in writing after any Registration Statement is declared effective. 

(iii) In the event of any stock split, stock dividend or transaction with respect to the Registrable Securities that increases the number of Registrable Securities, if a then-effective Registration Statement does not cover the resale of such additional number of Registrable Securities, the Company shall amend or supplement any Registration Statement to cover such additional number of Registrable Securities.

 

 

(iv) The Company shall use its best efforts to register or qualify the Registrable Securities covered by any Registration Statement under the securities laws of each state of the United States; provided, however, that the Company shall not be required in connection with this subsection (c)(iv) to qualify as a foreign corporation or execute a general consent to service of process in any jurisdiction.

(v) If the Company has delivered preliminary or final Prospectuses to the Investor and, after having done so, the Prospectus is amended or supplemented to comply with the requirements of the Securities Act, the Company shall promptly notify the Investor and, if requested by the Company, the Investor shall immediately cease making offers or sales of shares under the applicable Registration Statement and return all Prospectuses to the Company. The Company shall promptly provide the Investor with revised or supplemented Prospectuses and, following receipt of the revised or supplemented Prospectuses, the Investor shall be free to resume making offers and sales under the applicable Registration Statement.

(vi) The Company shall advise the Investor promptly after it shall receive notice or obtain knowledge of the issuance of any stop order by the SEC delaying or suspending the effectiveness of any Registration Statement or of the initiation or threat of any proceeding for that purpose, and it will promptly use commercially reasonable efforts to prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible moment if such stop order should be issued.

(d) Requirements of the Investor. The Company shall not be required to include any Registrable Securities in any Registration Statement contemplated by this Section 5 unless the Investor furnishes to the Company, in writing, such information regarding the Investor and the proposed sale of the Registrable Securities by the Investor as the Company may reasonably request in writing in connection with such Registration Statement or as shall be required in connection therewith by the SEC or any state securities law authorities.

(e) Suspension. The Company may suspend the use of any Registration Statement or Prospectus (a “Suspension”) by the Investor if the Company determines in good faith that such Suspension is necessary to (x) delay the disclosure of material non-public information concerning the Company, the disclosure of which at the time, in the good faith opinion of the Company’s Board of Directors, would be materially detrimental to the Company or its stockholders for a registration to be effected at such time; (y) amend or supplement the affected Registration Statement or the related Prospectus so that such Registration Statement or Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein; or (z) amend or supplement the affected Registration Statement or Prospectus in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, in each case of clauses (x) through (z), that the Company shall (a) promptly notify the Investor in writing of such Suspension and the reasons therefor, but shall not disclose to the Investor any material non-public information giving rise to a Suspension under clause (x); (b) advise the Investor in writing to cease all sales under the Registration Statement or Prospectus until the end of the Suspension; and (c) use its reasonable 

 

 

best efforts to terminate such Suspension as promptly as practicable. The Company may not exercise its rights pursuant to this subsection (e) for more than ninety (90) days in the aggregate in any twelve (12) month period. 

(f) Expenses. Except as set forth below, the Company will pay all of the expenses incurred in connection with complying with this Section 5 (whether or not any Registration Statement or Prospectus becomes final or effective), including, without limitation: all registration, filing and printing fees, the Company’s counsel and accounting fees and expenses, costs and expenses associated with clearing the Registrable Securities for sale under applicable state securities laws (including, without limitation, fees, charges and disbursements of counsel in connection with such clearance), all listing fees, expenses incurred by the Company (but not the Investor) in connection with any “road show,” and reasonable fees, charges and disbursements of counsel to the Investor. The Company shall not be required to pay or reimburse the Investor for any underwriting discounts or commissions and fees of underwriters, selling brokers, dealer managers or similar securities industry professionals with respect to the Registrable Securities being sold. 

(g) Indemnification. 

(i) The Company agrees to indemnify and hold harmless the Investor, each underwriter, and each other person, if any, who controls the Investor or underwriter within the meaning of the Securities Act or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), from and against any losses, claims, damages or liabilities to which the Investor, such underwriter or controlling person may become subject (under the Securities Act, the Exchange Act, state securities or blue sky laws or otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement of a material fact contained in any registration statement covering the Shares or in any preliminary prospectus or final prospectus contained in such registration statement, or any amendment or supplement to such registration statement, or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company will reimburse the Investor for any reasonable legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim, or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement made in such registration statement, preliminary prospectus or prospectus, or any amendment or supplement in reliance upon and in conformity with written information relating to the Investor furnished to the Company by or on behalf of the Investor specifically for use in the preparation thereof or any statement or omission in any prospectus that is corrected in any subsequent prospectus that was delivered to the Investor prior to the pertinent sale or sales by the Investor.

(ii) The Investor agrees to indemnify and hold harmless the Company, each underwriter and each person, if any, who controls the Company within the meaning of 

 

 

Section 15 of the Securities Act, each officer of the Company who signs the registration statement and each director of the Company, from and against any losses, claims, damages or liabilities to which the Company or any such underwriter, officer, director or controlling person may become subject under the Securities Act, the Exchange Act, state securities or blue sky laws or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement of a material fact contained in any registration statement covering the Shares or in any preliminary prospectus, final prospectus contained in such registration statement, or any amendment or supplement to such registration statement or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, if such untrue statement or omission was made in reliance upon and in conformity with written information relating to the Investor furnished by or on behalf of the Investor specifically for use in preparation of the registration statement, prospectus, amendment or supplement and the Investor will reimburse the Company, or such underwriter, officer, director or controlling person, as the case may be, for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Investor’s obligation to indemnify the Company shall be limited to the net amount received by the Investor from the sale of the Shares.

(iii) Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 5(g), such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 5(g) (except to the extent that such omission materially and adversely affects the indemnifying party’s ability to defend such action). Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person, the indemnifying person shall be entitled to participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the defense thereof, such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the opinion of counsel to the indemnified person, for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel (together with appropriate local counsel) for all indemnified parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person shall have approved the terms of such settlement; 

 

 

provided, however, that such consent shall not be unreasonably withheld. No indemnifying person shall, without the prior written consent of the indemnified person, effect any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could have been a party and indemnification could have been sought hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability on claims that are the subject matter of such proceeding.

(iv) If the indemnification provided for in this Section 5(g) is unavailable to or insufficient to hold harmless an indemnified party under subsections (g)(i) or (ii) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Investor, as well as any other selling stockholders under such registration statement on the other in connection with the statements or omissions or other matters which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or the Investor or other selling stockholder on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and the Investor agree that it would not be just and equitable if contribution pursuant to this subsection (g)(iv) were determined by pro rata allocation (even if the Investor and other selling stockholders were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection (g)(iv). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (g)(iv) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (g)(iv), the Investor shall not be required to contribute any amount in excess of the amount by which the net amount received by the Investor from the sale of the Shares to which such loss relates exceeds the amount of any damages which the Investor has otherwise been required to pay by reason of such untrue statement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(the “Representatives”) are acting as representatives, 4,000,000 shares of common stock, $0.001 par value per share (“Common Stock”) of the Issuer (said shares to be issued and sold by the Issuer being hereinafter called the “Underwritten Securities”). The Issuer also proposes to grant to the Underwriters an option to purchase up to 600,000 additional shares of Common Stock to cover over-allotments, if any (the “Option Securities;” the Option Securities, together with the Underwritten Securities, hereinafter called the “Securities”). To the extent there are no additional Underwriters listed on Schedule I other than you, the term Representatives as used herein shall mean you, as Underwriters, and the terms Representatives and Underwriters shall mean either the singular or plural as the context requires. The offering and sale of the Securities contemplated by this Agreement is referred to herein as the “Offering.”

 

 

1. Representations and Warranties. The Issuer represents and warrants to, and agrees with, each Underwriter as set forth below in this Section 1:

(a) The Issuer has prepared and filed with the Securities and Exchange Commission (the “SEC”) a registration statement (file number 333-221050) on Form S-1 including exhibits and financial statements and any prospectus supplement relating to the Securities that is filed with the SEC pursuant to Rule 424(b) under the Securities Act and deemed part of such registration statement pursuant to Rule 430A under the Securities Act, as amended at the Execution Time (as defined herein) and, in the event any post-effective amendment thereto or any registration statement and any amendments thereto filed pursuant to Rule 462(b) under the Securities Act (as defined herein) relating to the Offering (the “Rule 462(b) Registration Statement”) becomes effective prior to the Closing Date (as defined herein), shall also mean such registration statement as so amended or such Rule 462(b) Registration Statement, as the case may be (the “Registration Statement”), including the Preliminary Prospectus (as defined herein), for registration under the Securities Act of 1933, as amended, and the rules and regulations of the SEC promulgated thereunder (the “Securities Act”) of the Offering. Such Registration Statement, including any amendments thereto filed prior to the date and time that this agreement (the “Underwriting Agreement”) is executed and delivered by the parties hereto (the “Execution Time”), has become effective under the Securities Act. The Issuer may have filed one or more amendments thereto, including a related preliminary prospectus relating to the Securities which is used prior to the filing of the Prospectus (the “Preliminary Prospectus”), each of which has previously been furnished to you. The Issuer will file with the SEC a final prospectus relating to the Securities in accordance with Rule 424(b) after the Execution Time (the “Prospectus”). As filed, such Prospectus shall contain all information required by the Securities Act and the rules thereunder and, except to the extent the Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the latest Preliminary Prospectus) as the Issuer has advised you, prior to the Execution Time, will be included or made therein;

(b) On each date and time that the Registration Statement, any post-effective amendment or amendments thereto and any Rule 462(b) Registration Statement became or becomes effective (the “Effective Date”), the Registration Statement did, and when the Prospectus is first filed in accordance with Rule 424(b) under the Securities Act and on the Closing Date and on any date on which Option Securities are purchased, if such date is not the Closing Date (a “settlement date”), the Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Securities Act and the rules thereunder; on the Effective Date, at the Execution Time and on the Closing Date, the Registration Statement did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date and any settlement date, the 

 

 

Prospectus (together with any supplement thereto) will not include 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; provided, however, that the Issuer makes no representations or warranties as to the information contained in or omitted from the Registration Statement, or the Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Issuer by or on behalf of any Underwriter through the Representatives specifically for inclusion in the Registration Statement or the Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 8 hereof;

The preceding sentence does not apply to statements in or omissions from the Disclosure Package based upon and in conformity with written information furnished to the Issuer by or on behalf of any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any Underwriter consists of the information described as such in Section 8 hereof;

The Issuer will use 

 

 

its reasonable best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its reasonable best efforts to have such amendment or new registration statement declared effective as soon as practicable; 

(b) If, at any time prior to the filing of the Prospectus pursuant to Rule 424(b) under the Securities Act, any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein in the light of the circumstances under which they were made at such time not misleading, the Issuer will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request;

thereto as the Representatives may reasonably request.   The Issuer will pay the expenses of printing or other production of all documents relating to the Offering;

(f) The Issuer will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may reasonably designate and will use its reasonable best efforts to maintain such qualifications in effect so long as required for the distribution of the Securities; provided that in no event shall the Issuer be (i) obligated to qualify to do business in any jurisdiction where it is not now so qualified, (ii) obligated to take any action that would subject it to service of process in suits, other than those arising out of the Offering, in any jurisdiction where it is not now so subject or (iii) subject itself to taxation in any jurisdiction in which it is not otherwise subject to taxation on the date hereof.

with clauses (iii), (iv) or (v) of this paragraph do not exceed 10% of the number of shares of Common Stock outstanding immediately after the issuance and sale of the Securities and (y) each recipient of any such shares or other securities agrees to restrictions on the resale of securities that are consistent with the provisions set forth in the lock-up letter described in Section 6(j) for the remainder of the 180-day restricted period;

(h) If Citigroup Global Markets Inc. and Cowen and Company, LLC, in their sole discretion, agree to release or waive the restrictions set forth in a lock-up letter described in Section 6(j) hereof for an officer or director of the Issuer and provides the Issuer with notice of the impending release or waiver at least three Business Days before the effective date of the release or waiver, the Issuer agrees to announce the impending release or waiver by a press release substantially in the form of Exhibit D hereto through a major news service at least two Business Days before the effective date of the release or waiver;

(i) The Issuer will not take, directly or indirectly, without giving effect to the activities by the Underwriters, any action designed to or that would constitute or that would reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Issuer to facilitate the sale or resale of the Securities;

(j) The Issuer agrees to pay the costs and expenses relating to the following matters:  (i) the preparation, printing or reproduction and filing with the SEC of the Registration Statement (including financial statements and exhibits thereto), each Preliminary Prospectus, the Prospectus and each Issuer Free Writing Prospectus, and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Prospectus, the Prospectus and each Issuer Free Writing Prospectus, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the Offering; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities, including any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) the printing (or reproduction) and delivery of this Underwriting Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the Offering; (v) the registration of the Securities under the Exchange Act and the listing of the Securities on the NASDAQ Global Market; (vi) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification); (vii) any filings required to be made with the Financial Industry Regulatory Authority, Inc.

(k) The Issuer agrees that, unless it has or shall have obtained the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Issuer that, unless it has or shall have obtained, as the case may be, the prior written consent of the Issuer, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a Free Writing Prospectus required to be filed by the Issuer with the SEC or retained by the Issuer under Rule 433 under the Securities Act; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule II hereto and any electronic road show.  Any such free writing prospectus consented to by the Representatives or the Issuer is hereinafter referred to as a “Permitted Free Writing Prospectus.”  The Issuer agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the SEC, legending and record keeping;

6. Conditions to the Obligations of the Underwriters.  The obligations of the Underwriters to purchase the Underwritten Securities and the Option Securities, as the case may be, shall be subject to the accuracy of the representations and warranties on the part of the Issuer contained herein as of the Execution Time, the Closing Date and any settlement date pursuant to 

 

 

Section 3 hereof, to the accuracy of the statements of the Issuer made in any certificates pursuant to the provisions hereof, to the performance by the Issuer of its obligations hereunder and to the following additional conditions:

(e) The Issuer shall have furnished to the Representatives a certificate of the Issuer, signed by the Chief Executive Officer and the Chief Operating Officer and Chief Financial Officer of the Issuer, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Disclosure Package, the Prospectus and any amendment or supplement thereto, as well as each electronic road show used in connection with the Offering, and this Underwriting Agreement and that:

(i) the representations and warranties of the Issuer in this Underwriting Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Issuer has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

 

 

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the Issuer’s knowledge, threatened; and

(h) Prior to the Closing Date, the Issuer shall have furnished to the Representatives such further customary information, certificates and documents as the Representatives may reasonably request.

7. Reimbursement of Underwriters’ Expenses.  If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Issuer to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Issuer will reimburse the Underwriters severally through Citigroup Global Markets Inc. on demand for all reasonable and documented out of pocket expenses (including reasonable fees and documented disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution.

(a) The Issuer agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees, affiliates (within the meaning of Rule 405 under the Securities Act, each an “Affiliate”) and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereof, or in any Preliminary Prospectus, or the Prospectus, or any Issuer Free Writing Prospectus, or any Written Testing-the-Waters Communication or in any amendment thereof or supplement thereto or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other out of pocket expenses 

 

 

reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuer will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with information furnished in writing to the Issuer by or on behalf of any Underwriter through the Representatives specifically for inclusion therein.  This indemnity agreement will be in addition to any liability which the Issuer may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Issuer, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Issuer within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Issuer to each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Issuer by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity.  This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.  The Issuer acknowledges that the statements set forth (i) in the last paragraph of the cover page regarding delivery of the Securities and, under the heading “Underwriting,” (ii) the list of Underwriters and their respective participation in the sale of the Securities, (iii) the paragraph related to concessions and reallowances and (iv) the paragraphs related to stabilization in the Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus. 

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above.  The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party.  Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable and documented fees, costs and expenses of such separate counsel (which, if 

 

 

the Issuer is the indemnifying party, shall be limited to one such separate counsel for any Underwriter together with all persons who control such Underwriter within the meaning of either the Act or the Exchange Act) if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.  An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Issuer and the Underwriters severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Issuer and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuer on the one hand and by the Underwriters on the other from the Offering.  If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Issuer and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuer on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations.  Benefits received by the Issuer shall be deemed to be equal to the total net proceeds from the Offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Issuer on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission.  The Issuer and the Underwriters agree that it would not be just and equitable if contribution 

 

 

were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above.  Notwithstanding the provisions of this paragraph (d), (i) in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the Offering exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Issuer within the meaning of either the Securities Act or the Exchange Act, each officer of the Issuer who shall have signed the Registration Statement and each director of the Issuer shall have the same rights to contribution as the Issuer, subject in each case to the applicable terms and conditions of this paragraph (d). 

9. Default by an Underwriter.  If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Underwriting Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule I hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such non-defaulting Underwriters do not purchase all the Securities, this Underwriting Agreement will terminate without liability to any non-defaulting Underwriter or the Issuer.  In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Prospectus or in any other documents or arrangements may be effected.  Nothing contained in this Underwriting Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Issuer and any non-defaulting Underwriter for damages occasioned by its default hereunder.

10. Termination.  This Underwriting Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Issuer prior to delivery of and payment for the Securities, if at any time prior to such delivery and payment (i) trading in the Issuer’s Common Stock shall have been suspended by the SEC, the NASDAQ Global Market or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on either of such exchanges, (ii) a 

 

 

banking moratorium shall have been declared either by Federal or New York State authorities, (iii) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the Offering or delivery of the Securities as contemplated by the Preliminary Prospectus or the Prospectus (exclusive of any supplement thereto).   

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Issuer or its officers and of the Underwriters set forth in or made pursuant to this Underwriting Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Issuer or any of the officers, directors, employees, agents, Affiliates or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities.  The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Underwriting Agreement.

12. Notices.

14. Jurisdiction.  The Issuer agrees that any suit, action or proceeding against the Issuer brought by any Underwriter, the directors, officers, employees, Affiliates and agents of any Underwriter, or by any person who controls any Underwriter, arising out of or based upon this Underwriting Agreement or the transactions contemplated hereby may be instituted in any State or U.S. federal court in The City of New York and County of New York, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the non-exclusive jurisdiction of such courts in any suit, action or proceeding.  The Issuer hereby appoints René Russo, Pharm.D., BCPS, Arsanis, Inc., 890 Winter Street, Suite 230, Waltham, Massachusetts 02451, as its authorized agent (the “Authorized Agent”) upon whom process may be served in any suit, action or proceeding arising out of or based upon this Underwriting Agreement or the transactions contemplated herein that may be instituted in any State or U.S. federal court in The City of New York and County of New York, 

 

 

by any Underwriter, the directors, officers, employees, Affiliates and agents of any Underwriter, or by any person who controls any Underwriter, and expressly accepts the non-exclusive jurisdiction of any such court in respect of any such suit, action or proceeding.  The Issuer hereby represents and warrants that the Authorized Agent has accepted such appointment and has agreed to act as said agent for service of process, and the Issuer agrees to take any and all action, including the filing of any and all documents that may be necessary to continue such appointment in full force and effect as aforesaid.

Furthermore, the Issuer agrees that it is solely responsible for making its own judgments in connection with the Offering (irrespective of whether any of the Underwriters has advised or is currently advising the Issuer on related or other matters).  The Issuer agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Issuer, in connection with such transaction or the process leading thereto.

16. Integration. This Underwriting Agreement supersedes all prior agreements and understandings (whether written or oral) between the Issuer and the Underwriters, or any of them, with respect to the subject matter hereof.

EXHIBIT 10.16 

FEDERAL HOME LOAN BANK OF CHICAGO
2018 BOARD OF DIRECTORS COMPENSATION POLICY

GENERAL

Section 1261.21 of the Rules and Regulations of the Federal Housing Finance Agency requires the Board of Directors to adopt a written policy to provide for the payment of reasonable compensation to Bank Directors for the performance of their duties as members of the Board of Directors. Pursuant to that regulation, this 2018 Board of Directors' Compensation Policy ("Policy") sets forth the activities and functions for which attendance is necessary and appropriate and may be compensated, and sets forth the methodology for determining the amount of compensation to be paid. This Policy shall be reviewed annually by the Human Resources & Compensation Committee. 

COMPENSATION POLICY METHODOLOGY

The goal of the Policy is to appropriately compensate the Directors for actual attendance and participation at the meetings of the Board of Directors and the committees of the Board and also for work performed on behalf of the Board of Directors and the Bank apart from such meetings.  

The compensation provided in this Policy was determined after a review of comparative compensation studies by third parties with expertise in the compensation of Directors (McLagan ”Director Compensation Detailed Analysis” May 2017) and the compensation paid to Directors of other Federal Home Loan Banks in 2017.

PAYMENT STRUCTURE

Members of the Board will receive the following maximum annual payments as designated for their position, as further calculated pursuant to this Policy.

	
			
	Position
	Maximum Annual Compensation
	Position Duties

	Chairman
	$137,000
	Preside at the meetings of the Board of Directors and the Executive & Governance Committee and attend other committee meetings.  Represent the Bank at the Council of FHLBs.

	Position Duties

	Vice Chairman
	$122,000
	Attend meetings of the Board and other committee meetings, as well as chair meetings of the Board in the Chairman’s absence.  Represent the Bank at the Council of FHLBs.

	Audit Committee Chairman
	$122,000
	Attend meetings of the Board and meetings of committees to which such Director is appointed, as well as chair meetings of the Audit Committee. 

	Committee Chairman

	Attend meetings of the Board and meetings of committees to which such Director is appointed, as well as chair meetings of committees to which such Directors is appointed Chairman.

	Director
	$105,000
	Attend meetings of the Board and meetings of committees to which such Director is appointed.

In order to compensate Directors for their time while serving as Directors, a Director shall receive one quarter of their Maximum Annual Compensation following the end of each quarter. The payment shall compensate Directors for their time preparing for and attending in-person and telephonic meetings, attending Bank-sponsored member meetings and events, attending Community Investment Advisory Council meetings, attending FHLB System meetings, Board training sessions, and other activities related to service on the Board of Directors. 

- 2 -

In the event that a Director serves on the Board for only a portion of a calendar year, or only serves as Chairman of the Board, Vice Chairman of the Board, or a Committee Chair for a portion of a calendar year, then the Maximum Annual Compensation to which such Director is entitled for that calendar year shall be adjusted accordingly on a pro-rata basis.  

DEFERRAL OF COMPENSATION

A Director may elect to defer compensation paid under this Policy in accordance with the Federal Home Loan Bank of Chicago Board of Directors Deferred Compensation Plan, effective September 1, 2013.

EXPENSES

Each Director will be reimbursed for necessary and reasonable travel, subsistence and other related expenses incurred in connection with the performance of their official duties (including telephonic meetings or in-person meetings called at the request of the Federal Housing Finance Agency or other FHLB System body) as are payable to senior officers of the Bank under the Bank’s Employee Reimbursement Policy.

Directors are authorized to purchase upgrades for air travel from economy to business class or economy plus only.  This does not include upgrades to first class.  Air travel upgrades shall not exceed $100 per flight.

Pursuant to IRS tax code, certain Director expenses paid for by the Bank that do not qualify as a business-related expense will be recorded as other income and reported on a Director’s 1099 tax form for the appropriate reporting period.  

Each Director is responsible for all expenses incurred in conjunction with spousal travel. 

PERFORMANCE AND ATTENDANCE STANDARDS

The following performance criteria shall be considered in assessing a Director’s performance:

		
	*
	Did the Director satisfy the attendance standard (described below) for Board and committee meetings during the specific assessment period?

		
	*
	Did the Director attend most of his or her scheduled in-person meetings in person?

- 3 -

		
	*
	Was the Director prepared for meetings? 

		
	*
	Did the Director demonstrate knowledge of Bank policies and other relevant governance documents?

		
	*
	Did the Director demonstrate understanding of the FHLB System? 

		
	*
	Did the Director actively participate in meetings? 

		
	*
	Did the Director participate in education and training during the specific assessment period?

		
	*
	Did the Director make decisions or suggestions that support the Bank’s mission and vision?

		
	*
	Did the Director support Board decisions, even if he or she did not agree with the decision?

		
	*
	Did the Director maintain confidentiality of the discussions at meetings? 

		
	*
	Did the Director participate in Bank-related events (i.e., FHLB System meetings, member meetings, Bank-sponsored conferences, etc.)?

		
	*
	If a new Director, did the Director participate in all new Director training and educational opportunities?

Each Director shall fulfill his or her responsibilities by regularly and consistently attending meetings of the Board of Directors and any assigned committees.  The Board's attendance standard shall be to attend in person or by telephone at least 75% of the total meetings of the Board and assigned committees, measured annually.  

The Chairman of the Board, Vice Chairman of the Board and Chairman of the Human Resources & Compensation Committee (each, a “Reviewer”) shall evaluate each Director’s attendance and performance bi-annually, prior to the release of the second quarter and fourth quarter payments.  The Reviewers may elect to reduce or eliminate the second and/or fourth quarter payment to any Director who does not fulfill his or her responsibilities by failing to meet the majority of the performance criteria set forth above.  A Director’s second quarter payment may also be reduced if it is deemed that the Director’s attendance at meetings of the full Board or committees to which the Director is appointed is not adequate.  

- 4 -

A Director’s fourth quarter payment will be eliminated if it is determined at the end of the calendar year that a Director has attended fewer than 75% of the combined meetings of the full Board and committees on which the Director serves (including in-person and telephonic) during such year.  

In the event that a Director serves on the Board for only a portion of a calendar year, the Reviewers shall evaluate the Director’s attendance and performance following the Director’s departure and prior to the release of the Director’s final payment, regardless of whether such review falls within the bi-annual review schedule for all Directors.  The Reviewers may elect to reduce or eliminate the final payment if it is determined that the Director did not fulfill his or her responsibilities by failing to meet the majority of the performance criteria set forth above.  The Director’s final payment will be eliminated if it is determined that the Director failed to attend 75% of the total meetings of the Board of Directors and any assigned committees measured on a pro-rata basis, based on the number of meetings of the full Board and committees on which the Director served during the year up until the Director’s date of resignation.  

Actions to reduce or eliminate a compensation payment requires a majority vote of the Reviewers except in the case where a Reviewer has recused themselves from the evaluation process.  The Reviewers will each recuse themselves from evaluating their own attendance and performance.  Any decision to reduce or eliminate a compensation payment, consistent with the terms of this Policy,  must be unanimous among the other two Reviewers.  In the event the Vice Chairman of the Board is also the Chairman of the Human Resources & Compensation Committee, the decision to reduce or eliminate a compensation payment to the individual, consistent with the terms of this Policy, will be at the sole discretion of the Chairman of the Board.

The Reviewers may designate a Director’s absence for a good cause from a scheduled meeting as an “excused absence.”  An “excused absence” shall be recorded as a Director in attendance for the 75% attendance standard.  Examples of what may be an “excused absence” include, but are not limited to, a medical condition of the Director or their immediate family or an unexpected business conflict pertaining to the Director’s primary business.

- 5 -

POLICY INTERPRETATION

The Bank’s Corporate Secretary is authorized to interpret the provisions of this Policy and to address situations not anticipated by this Policy, consistent with all applicable regulatory requirements and statutes.

COMPLIANCE WITH LEGAL REQUIREMENTS

This Policy shall be in compliance with Section 7(i) of the Federal Home Loan Bank Act (12 U.S.C. §1427(i)), as amended, and any regulations issued by the Federal Housing Finance Agency, including 12 C.F.R. Part 1261.
