Item 3. Incorporation of Documents by Reference.

 

We incorporate by reference herein the following documents filed by Mersana Therapeutics, Inc. (the “Registrant”) with the Commission:

 

(a)the Registrant’s Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Commission on February 26, 2021, 2021;

Item 4. Description of Securities.

 

Not applicable.

 

Item 5. Interests of Named Experts and Counsel.

 

Not applicable.

 

Item 6. Indemnification of Directors and Officers.

 

The Registrant’s amended and restated certificate of incorporation contains a provision that eliminates, to the maximum extent permitted by the General Corporation Law of the State of Delaware, the personal liability of directors for monetary damages for breach of their fiduciary duties as a director. The Registrant’s amended and restated bylaws provide that the Registrant shall indemnify its directors and executive officers to the fullest extent permitted by the General Corporation Law of the State of Delaware.

 

Sections 145 and 102(b)(7) of the General Corporation Law of the State of Delaware provide that a corporation may indemnify any person made a party to an action by reason of the fact that he or she was a director, executive officer, employee or agent of the corporation or is or was serving at the request of the corporation against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with such action if he or she acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful, except that, in the case of an action by or in right of the corporation, no indemnification may generally be made in respect of any claim as to which such person is adjudged to be liable to the corporation.

 

The Registrant has entered into indemnification agreements with each of its directors and executive officers, in addition to the indemnification provided for the Registrant’s amended and restated bylaws, and intends to enter into indemnification agreements with any new directors and executive officers in the future.

 

The Registrant maintains insurance on behalf of any person who is or was a director or officer of the Registrant against any loss arising from any claim asserted against him or her and incurred by him or her in any such capacity, subject to certain exclusions.

Item 9. Undertakings.

 

(a) The undersigned Registrant hereby undertakes:

 

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

 

(i)To include any prospectus required by Section 10(a)(3) of the Securities Act;

 

(ii)To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of a prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement;

 

(iii)To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

 

 provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above shall not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.

 

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

 

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

 

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Ladies and Gentlemen:

 

This opinion letter is furnished to you in connection with the registration statement on Form S-8 (the “Registration Statement”), filed by Mersana Therapeutics, Inc., a Delaware corporation (the “Company”), on the date hereof, with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”), for the registration of (i) 2,753,651 shares of common stock, $0.0001 par value, of the Company (the “Plan Shares”) issuable under the Mersana Therapeutics, Inc. 2017 Stock Incentive Plan (the “Plan”) and (ii) 532,500 shares of common stock, $0.0001 par value, of the Company (together with the Plan Shares, the “Shares”) that may be issued, in the aggregate, upon exercise of inducement stock option awards (the “Inducement Awards”) granted to Charles Miller, Arvin Yang, Carla Poulson and Alejandra Carvajal on August 31, 2020, November 30, 2020, January 19, 2021 and April 26, 2021, respectively.

 

We are familiar with the actions taken by the Company in connection with the adoption of the Plan and the grants of the Inducement Awards. We have examined such certificates, documents and records and have made such investigation of fact and such examination of law as we have deemed appropriate in order to enable us to render the opinions set forth herein. In conducting such investigation, we have relied, without independent verification, upon certificates of officers of the Company, public officials and other appropriate persons.

 

The opinions expressed below are limited to the Delaware General Corporation Law.

 

Based upon and subject to the foregoing, we are of the opinion that the Shares have been duly authorized and, when the Shares have been issued and sold in accordance with the terms of the Plan or the applicable Inducement Award, the Shares will be validly issued, fully paid and nonassessable.

 

We hereby consent to the filing of this opinion letter as an exhibit to the Registration Statement. In giving such consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations thereunder.

 

  Very truly yours,

MERSANA THERAPEUTICS, INC.

 

Inducement Stock Option Agreement

 

This agreement (this “Agreement”) evidences a stock option (the “Stock Option”) granted by the Company to the individual named above (the “Optionee”), as an inducement material to the Optionee’s entering into employment with the Company. The Stock Option has been granted as an “inducement” award under Nasdaq Listing Rule 5635(c)(4), and as such, the Stock Option has been granted outside the Company’s existing equity compensation plans. However, the Stock Option will be governed in all respects as if issued pursuant to and subject to the terms of the Mersana Therapeutics, Inc. 2017 Stock Incentive Plan (as from time to time amended and in effect, the “Plan”).

 

1.            Meaning of Certain Terms. Except as otherwise defined herein, all capitalized terms used herein have the same meaning as in the Plan. The following terms have the following meanings:

 

(a)Beneficiary”: In the event of the Optionee’s death, the beneficiary named in the written designation (in a form acceptable to the Administrator) most recently filed with the Administrator by the Optionee prior to the Optionee’s death and not subsequently revoked, or, if there is no such designated beneficiary, the executor or administrator of the Optionee’s estate. An effective beneficiary designation will be treated as having been revoked only upon receipt by the Administrator, prior to the Optionee’s death, of an instrument of revocation in a form acceptable to the Administrator.

 

(b)Option Holder”: The Optionee or, if at the relevant time the Stock Option has passed to a Beneficiary, the Beneficiary.

 

2.            Grant of Stock Option. The Company grants to the Optionee on the date set forth above (the “Date of Grant”) the Stock Option to purchase, pursuant to and subject to the terms set forth in this Agreement and in the Plan, up to the number of shares of Stock set forth above (the “Shares”), with an exercise price per Share as set forth above, in each case, subject to adjustment pursuant to Section 7 of the Plan in respect of transactions occurring after the date hereof.

 

The Stock Option evidenced by this Agreement shall be treated as an NSO.

 

3.            Vesting; Method of Exercise; Cessation of Employment.

 

(a)Vesting. The term “vest” as used herein with respect to the Stock Option or any portion thereof means to become exercisable and the term “vested” as applied to any outstanding Stock Option means that the Stock Option is then exercisable, subject, in each case, to the terms of the Plan. Unless earlier terminated, forfeited, relinquished or expired, the Stock Option will vest as shown on the attached Exhibit A, with the number of Shares that vest on any such date being rounded down to the nearest whole share and the Stock Option becoming vested as to 100% of the Shares on the fourth anniversary of the Vesting Commencement Date, subject, in each case, to the Optionee remaining in continuous Employment from the date of this Agreement through such vesting date.

 

 

 

 

(b)Exercise of the Stock Option. No portion of the Stock Option may be exercised until such portion vests. Each election to exercise any vested portion of the Stock Option will be subject to the terms and conditions of the Plan and must be in written or electronic form acceptable to the Administrator, signed (including by electronic signature) by the Option Holder (or in such other form as is acceptable to the Administrator). Each such written or electronic exercise election must be received by the Company at its principal office or by such other party as the Administrator may prescribe and be accompanied by payment in full of the exercise price, which may be paid by cash or check or, to the extent permitted by applicable law and the regulations promulgated under Section 424 of the Code, through a broker-assisted exercise program acceptable to the Administrator. The latest date on which the Stock Option or any portion thereof may be exercised is the 10th anniversary (or the 5th anniversary, in the case of a 10-percent stockholder within the meaning of Section 422(b)(6) of the Code) of the Date of Grant (the “Final Exercise Date”) and, if not exercised by such date, the Stock Option or any remaining portion thereof will thereupon immediately terminate.

 

(c)Cessation of Employment. If the Optionee’s Employment ceases, except as expressly provided for in an employment or other individual agreement between the Optionee and the Company or its Affiliate, the Stock Option, to the extent not already vested, will be immediately forfeited, and any vested portion of the Stock Option that is then outstanding will be treated as provided in the Plan. .

 

(d)Disqualifying Disposition. If the Optionee disposes of any Shares acquired upon exercise of the Stock Option within two years from the Date of Grant or within one year after such Shares were acquired pursuant to the exercise of the Stock Option, within 15 days following such disposition, the Optionee shall notify the Company in writing of such disposition.

 

4.            Forfeiture; Recovery of Compensation.

 

(a)The Stock Option, and the proceeds from the exercise or disposition of the Stock Option or the Shares, will be subject to forfeiture and disgorgement to the Company, with interest and related earnings, if at any time the Optionee is not in compliance with all applicable provisions of this Agreement and the Plan.

 

(b)By accepting, or being deemed to have accepted, the Stock Option, the Optionee expressly acknowledges and agrees that his or her rights, and those of any permitted transferee of the Stock Option, under the Stock Option, including the right to any Stock acquired under the Stock Option or proceeds from the disposition thereof, are subject to Section 6(a)(5) of the Plan (including any successor provision). Nothing in the preceding sentence may be construed as limiting the general application of Section 8 of this Agreement.

 

-2

 

 

5.             Nontransferability. The Stock Option may not be transferred except as expressly permitted under Section 6(a)(3) of the Plan.

 

6.          Withholding. The Optionee expressly acknowledges and agrees that the Optionee’s rights hereunder, including the right to be issued Shares upon exercise, are subject to the Optionee promptly paying to the Company in cash or by check (or by such other means as may be acceptable to the Administrator) all taxes required to be withheld. No Shares will be issued pursuant to the exercise of the Stock Option unless and until the person exercising the Stock Option has remitted to the Company an amount in cash sufficient to satisfy any federal, state, or local withholding tax requirements, or has made other arrangements satisfactory to the Company with respect to such taxes. The Optionee authorizes the Company and its subsidiaries to withhold such amount from any amounts otherwise owed to the Optionee, but nothing in this sentence may be construed as relieving the Optionee of any liability for satisfying his or her obligation under the preceding provisions of this Section.

 

7.            Effect on Employment. Neither the grant of the Stock Option, nor the issuance of Shares upon exercise of the Stock Option, will give the Optionee any right to be retained in the employ or service of the Company or any of its subsidiaries, affect the right of the Company or any of its subsidiaries to terminate the Optionee’s Employment at any time, or affect any right of the Optionee to terminate his or her Employment at any time.
