ARTICLE IV

COVENANTS

4.1 Resale Registration.

(a) The Company shall use commercially reasonable efforts to file as promptly as practicable after the Effective Date, but in no event earlier than the date on which the Company first files a Quarterly Report on Form 10-Q following the Effective Date (which the Company currently expects to file on April 30, 2020), with the SEC a registration statement with respect to the public resale by the Rightholders of the Stock Consideration on a continuous or delayed basis pursuant to Rule 415 under the Securities Act, in respect of which the Company may use a registration statement on Form S-3 (or any successor form registration statement available for such resale which permits incorporation by reference of the Company’s filings with the SEC to at least the same extent as such form) to the extent the Company is then eligible for its use (the “Registration Statement”), and cause the Registration Statement to become automatically effective upon filing if eligible to do so or if not eligible to do so, then use commercially reasonable efforts to take such actions as are necessary to cause such Registration Statement to become effective.

(b) The Company shall keep the Registration Statement effective under the Securities Act (and maintain the current status of the prospectus or prospectuses contained therein) until the date that is the six month anniversary of the Effective Date or such earlier time as all of the shares of the Stock Consideration have been sold pursuant thereto; provided, that the obligation to keep such Registration Statement effective under this Section 4.1(b) shall not apply during the pendency of any Force Majeure Event to the extent such Force Majeure Event is the reason for or cause of an inability to keep such Registration Statement effective. The Company will promptly notify SRS (on behalf of the Rightholders) of the time the Registration Statement became effective or a supplement to any prospectus forming a part of the Registration Statement has been filed.

(c) The Company may, by written notice to SRS (on behalf of the Rightholders), suspend the use of the Registration Statement after effectiveness and require that the Rightholders immediately cease sales of shares pursuant to the Registration Statement, in the event that (i) the Company engages in a public offering of its securities (an “Offering Suspension”) or (ii) the Company is engaged in any activity, matter or transaction or preparations or negotiations for any activity, matter or transaction that the Company desires to keep confidential for business reasons, if the Company determines in good faith, upon advice of counsel, that the public disclosure requirements imposed on the Company under the Securities Act in connection with the Registration Statement would require disclosure of such activity, transaction, preparations or negotiations (a “Confidentiality Suspension”). Each Rightholder agrees to keep and hold confidential the fact of, and any information contained or referenced

in, any such notice described in this Section 4.1(c). The Company may suspend the use of the Registration Statement by requiring Rightholders to cease sales of shares of Stock Consideration upon notice to such Rightholders of an Offering Suspension or a Confidentiality Suspension, provided that such suspensions, taken together, are not used more than three times in the aggregate or for more than thirty (30) Business Days in the aggregate.

(d) If the Company suspends the use of the Registration Statement by notice to SRS (on behalf of the Rightholders) and requires the Rightholders to cease sales of shares pursuant to this Section 4.1, the Company shall, as promptly as practicable following the termination of the circumstance which entitled the Company to do so, take such actions as may be necessary to reinstate the effectiveness of the Registration Statement and/or give written notice to SRS (on behalf of the Rightholders) authorizing them to resume sales pursuant to the Registration Statement. If as a result thereof the prospectus included in the Registration Statement has been amended to comply with the requirements of the Securities Act, the Company shall enclose such revised prospectus with the notice to SRS (on behalf of the Rightholders) given pursuant to this Section 4.1(d), and the Rightholders shall make no offers or sales of shares pursuant to the Registration Statement other than by means of such revised prospectus.

(e) Promptly following the filing by the Company of the Registration Statement, the Company shall furnish to each Rightholder a copy of the prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act. The Company shall promptly provide (and in any event within the time periods specified in Section 4.1(c)) the Rightholders with revised or supplemented prospectuses and, following receipt of the revised or supplemented prospectuses, the Rightholders shall be free to resume making offers and sales under the Registration Statement. The Company shall pay the expenses incurred by it in complying with its obligations under this Section 4.1, including all registration and filing fees, exchange listing fees, fees and expenses of counsel for the Company, and fees and expenses of accountants for the Company, but excluding (i) any brokerage fees, selling commissions or underwriting spread or discounts incurred by the Rightholders in connection with sales under the Registration Statement and (ii) the fees and expenses of any counsel retained by or on behalf of the Rightholders.

(f) The Company shall not be required to include any shares of Stock Consideration in the Registration Statement unless:

(i) the Rightholder owning such shares furnishes to the Company in writing such information regarding such Rightholder and the proposed sale of Stock Consideration by such Rightholder as the Company may reasonably request in writing in connection with the Registration Statement or as shall be required in connection therewith by the SEC or any state securities law authorities; and

(ii) such Rightholder shall have provided to the Company its written agreement in substantially the form attached as Exhibit A hereto:

(A) to indemnify the Company and each of its directors and officers against, and hold the Company and each of its directors and officers harmless from, any losses, claims, damages, expenses or liabilities (including reasonable attorney’s fees) to which the Company or such directors and officers may become subject by reason of any statement or omission in the Registration Statement made in reliance upon, or in conformity with, a written statement by such Rightholder furnished pursuant to this Section 4.1; and

(B) to report to the Company sales made pursuant to the Registration Statement; and

(iii) such Rightholder shall have provided to the Company completed and signed questionnaires in the forms attached as Exhibits A and B hereto.

(g) Solely for purposes of Section 4.1, the Company agrees to indemnify and hold harmless each Rightholder whose shares of Stock Consideration are included in the Registration Statement against any losses, claims, damages, expenses or liabilities to which such Rightholder may become subject by reason of any untrue statement of a material fact contained in the Registration Statement or any omission to state therein a fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages, expenses or liabilities arise out of or are based upon information furnished to the Company by or on behalf of the Company or a Rightholder for use in the Registration Statement. The Company shall have the right to assume the defense and settlement of any claim or suit for which the Company may be responsible for indemnification under this Section 4.1.

4.2 Further Assurances. From time to time after the Effective Date, upon request of any Party, each Party shall execute, acknowledge and deliver all such other instruments and documents and shall take all such other actions required to consummate and make effective the transactions contemplated by this Agreement; provided that the Company shall not be required to pay any further consideration or amounts therefor.

4.3 Public Announcements. No Rightholder shall issue any press release or public announcement relating to the subject matter of this Agreement without the prior written approval of the Company; provided, however, that a Rightholder may make any public disclosure it believes in good faith is required by applicable law or stock market rule (in which case such Rightholder shall use reasonable best efforts to advise the Company and provide the Company with a copy of the proposed disclosure prior to making the disclosure).

4.4 Tax Treatment. For U.S. federal and applicable state income tax purposes, the Parties shall treat the cancellation and forfeiture of the Milestone Rights in exchange for the Stock Consideration and the Cash Consideration as an adjustment to the purchase price that the Company paid for the Rightholder’s Company Stock and/or Company Warrants (as defined in the Merger Agreement) in Agilis Biotherapeutics, Inc. pursuant to the Merger Agreement and in accordance with Section 9.3(f)(ii) of the Merger Agreement, the Stock Consideration and Cash Consideration shall be treated as a payment of deferred purchase price, except to the extent it is treated as imputed interest as required by Section 483 or 1274 of the Internal Revenue Code of 1986, as amended. In accordance with Section 9.3(f)(iii) of the Merger Agreement, any payment of Stock Consideration and Cash Consideration attributable to a Rightholder’s Company Options (as defined in the Merger Agreement) shall be treated for Tax purposes as a payment of compensation.
