considers necessary or advisable to secure its rights hereunder and to carry out the intent of this Agreement. 
 8. Specific
Performance. Employee agrees that any violation by her of Sections 6 or 7 of this Agreement would be highly injurious to the Company and would cause irreparable harm to the Company. By reason of the foregoing, Employee consents and agrees that

performance and/or injunctive or other equitable relief (without the requirement of posting of a bond or other security) in order to enforce, or prevent any continuing or potential violation of, the provisions of such Section(s). The Employee also
recognizes that the territorial, time and scope limitations set forth in Sections 6 and 7, as applicable, are reasonable and are properly required and necessary for the protection of the Company and in the event chat any such territorial, time or
scope limitation is deemed to be unreasonable by a court of competent jurisdiction, the Company and the Employee agree, and Employee submits, to the reduction of any or all of said territorial, time or scope limitations to such an area, period or
scope as said court shall deem reasonable under the circumstances. If such partial enforcement is not possible, the provision shall be deemed severed, and the remaining provisions of this Agreement shall remain in full force and effect. Employee
acknowledges that Sections 6 and 7 of this Agreement shall survive termination or expiration of the Employee’s employment. 
 9.
Termination. Notwithstanding the notice provision of Article 1 hereof, Employee’s employment with the Company: (i) shall terminate upon the Employee’s resignation, death or disability, (ii) may be terminated without prior

negligence or misconduct in the performance of Employee’s duties or (3) the commission by Employee of any act of embezzlement against Company or the commission of any felony or act involving moral turpitude. 

  

					
	Confidential	  		  	Page 6














 Except as hereinafter provided, effective as of the termination or expiration date of the
Employee’s employment hereunder for any reason, or for no reason, or in the event the Employee resigns, or her death or disability then, in any of such events, the Employee shall be paid her Base Salary and benefits through the date of
expiration or termination and all the rights and options granted to the Employee pursuant to Articles 3 and 4 hereof shall cease and terminate as of the date of the Employee’s termination, expiration or resignation and thereafter shall be null
and void and without further force or effect. Notwithstanding anything to the contrary herein contained, it is expressly agreed and understood that (i) if the Employee is terminated by the Company without cause, or the Employee terminates her
employment for Good Reason, as hereinafter defined, prior to a “Change of Control” then the Employee shall be entitled to severance payments equal to twelve (12) months continuation of her Base Salary, a
pro-rata share of any bonus for which the Employee was eligible, continuation of benefits for the twelve (12) months severance period (or additional compensation in an amount reflecting the cost to the
Company of such benefits if the benefit plans do not provide for continuation) and continued vesting of stock options for twelve (12) months. All severance payments of Base Salary and benefits pursuant to subsection (i) will be paid in
accordance with the provisions of Articles 3 and 4(a). Alternatively, if the Employee is terminated by the Company without cause, or the Employee terminates her employment for Good Reason, as hereinafter defined, within nine (9) months
following a “Change of Control,” the Employee shall be entitled to a one-time severance payment equal to twelve (12) months of her Base Salary as of the date of termination, and such severance
payment shall be paid as of the date of termination, If the Employee remains employed by the Company following the nine (9) months after a “Change of Control,” the severance benefits described in subsection (i) shall again apply.

 For purposes of this Agreement, “Good Reason” is defined to exist upon: 

 

	 	(A)	 The relocation of the Company’s offices such that the Employee’s daily commute is increased by at
least thirty (30) miles each way without the written consent of the Employee; 


  

	 	(B)	 Material reduction of the Employee’s Base Salary without the prior consent of the employee (other than in
connection with, and substantially proportionate to reductions by the Company of the Base Salary of more than 50% of its employees); 


  

	 	(C)	 Material diminution in Employee’s duties, authority or responsibilities without the prior consent of the
Employee, other than changes in duties, authority or responsibilities resulting from the Employee’s misconduct; 



Provided, however, that any reduction in duties, authority or responsibilities or reduction in the level of management to which the Employee
reports resulting solely from a Change in Control which results in the Company being acquired by and made a part of a larger entity shall not constitute Good Reason. 

10. Notice. Any notice provided for in this Agreement must be in writing and must be either personally delivered, mailed by first class
mail (postage prepaid and return receipt requested), sent by reputable overnight courier service (charges prepaid), or sent by confirmed facsimile at the address indicated below:

 or such other address and/or to the attention of such other person as the recipient party shall have designated by notice
given in accordance with this Section 10. All notices under this Agreement shall be deemed to have been given: (a) if delivered in person or sent by confirmed facsimile then on the date delivered, (b) if by overnight courier, one

11. Code Section 409 A Compliance. 

(a) The intent of the parties is that payments and benefits under this Agreement comply with, or be exempt from Code Section 409A,
and, accordingly, this Agreement shall be interpreted and applied so as to be in compliance therewith. The Company and the Executive agree to work together in good faith to consider amendments to this Agreement and to take such reasonable actions
which are necessary, appropriate or desirable to avoid imposition of any additional tax or income recognition prior to actual payment to the Executive under Section 409A. 

(b) A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment
of any amounts or benefits upon or following a termination of employment that are considered “non-qualified deferred compensation” under Code Section 409A unless such termination is also a
“separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination”, “termination of employment”, or like terms shall
mean “separation from service”. If the Executive is deemed on the date of termination to be a “specified employee” within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment that
is considered non-qualified deferred compensation under Code Section 409A payable on account of a “separation from service,” such payment or benefit shall be made or provided at the date
which is the earlier of (A) the expiration of the six (6)-month period measured from the date of such “separation from service” of the Executive, and (B) the date of the Executive’s death (the “Delay
Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section 26(b) (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay)
shall be paid or reimbursed to the Executive in a lump sum and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. 

(c) With regard to any provision herein that provides for reimbursement of costs and expenses or
in-kind benefits, except as permitted by Code Section 409A, (i) the right to reimbursement or in-kind benefits shall not be subject to liquidation or
exchange for another benefit, (ii) the amount of expenses eligible for reimbursement, or in-kind benefits, provided during any taxable year shall not affect the expenses eligible for reimbursement,
or in-kind benefits to be provided, in any other taxable year, provided that the foregoing clause (ii) shall not be

violated with regard to expenses reimbursed under any arrangement covered by Internal Revenue Code Section 105(b) solely because such expenses are subject to a limit related to the period
the arrangement is in effect and (iii) such payments shall be made on or before the last day of Executive’s taxable year following the taxable year in which the expense occurred. 

For purposes of Code Section 409A, the Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right
to receive a series of separate and distinct payments. In no event may the Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement that is considered nonqualified deferred compensation. In no
event shall the timing of Executive’s execution of the General Release, directly or indirectly, result in the Executive designating the calendar year of payment, and if a payment that is subject to execution of the General Release could be made
in more than one taxable year, payment shall be made in the later taxable year. 
 12. Indemnification. 

(a) To the fullest extent permitted under applicable law, Employee shall not be liable to the Company or any of its equity holders for any
loss, claim, damage or liability arising from any act or omission performed or omitted by the Employee in connection with the Company’s business or affairs (including any error in judgment in providing any advice or counsel), except for any
loss, claim, damage or liability primarily attributable to the Employee’s willful misconduct, recklessness, or gross negligence, as finally determined by a court of competent jurisdiction, or as otherwise required by law. 

(b) The Company shall, to the fullest extent permitted by applicable law, indemnify and hold the Employee harmless against any and all losses,
claims, damages, liabilities, costs or Expenses (as defined below) (including judgments and amounts paid in settlement) to which the Employee may become subject in connection with any matter arising out of or in connection with the Company’s
business or affairs, or by reason of the fact that the Employee is or was serving at the Company’s request as a director, officer, employee or agent of another corporation or other enterprise, unless (i) a court of competent jurisdiction,
in a judgment that has become final and that is no longer subject to appeal or review, determines that any such loss, claim, damage, liability, cost or Expense is primarily attributable to the Employee’s willful misconduct, recklessness, or
gross negligence, or (ii) it is determined in accordance with applicable law that the Employee did not act in good faith and did not reasonably believe that the Employee’s conduct was in or not opposed to the Company’s best interests
and, with respect to any criminal Proceeding (as defined below), had no reasonable cause to believe that the Employee’s conduct was unlawful. The termination of a Proceeding by judgment, order, settlement, or conviction, or upon a plea of nolo
contendere or its equivalent, is not, of itself, automatically determinative that Employee did not meet the relevant standard of conduct described in this subsection. 

(c) If any Employee becomes involved in any capacity in any Proceeding in connection with any matter arising out of or in connection with the
Company’s business or affairs, or by reason of the fact that the Employee is or was serving at the Company’s request as an Executive Chairman, director, officer, employee or agent of another corporation or other enterprise, the Company
shall pay (as they are incurred) the Employee’s Expenses (as defined below) incurred in connection therewith after the Company receives (i) a written affirmation by 

  

					
	Confidential	  		  	Page 9














 
the Employee of the Employee’s good faith belief that it has met the standard of conduct necessary for indemnification, and (ii) a written undertaking by or on behalf of the Employee to
repay to the Company the amount of any such Expense paid to the extent that it is ultimately determined that the Employee is not entitled to be indemnified by the Company in connection with such Proceeding as provided in the exceptions contained
herein or under applicable law. 
 (d) If for any reason (other than anything described in Section 12(b)(i) or (ii)) the foregoing
indemnification is unavailable to the Employee, or insufficient to hold it harmless, then the Company shall, to the fullest extent permitted by applicable law, contribute to the amount paid or payable by the Employee as a result of such loss, claim,
damage or liability in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Employee on the other hand or, if such allocation is not permitted by applicable law, to reflect not only the
relative benefits referred to above but also any other relevant equitable considerations. 
 (e) In any suit brought to enforce a right to
indemnification or to recover an advancement of Expenses, the burden of proving that the Employee is not entitled to be indemnified, or to an advancement of Expenses, hereunder is on the Company (or any equity holder of the Company acting
derivatively or otherwise on behalf of the Company or its equity holders). 
 (f) As used in this Agreement, 

(i) the term “Proceeding” means (i) any threatened, pending or completed action, suit, arbitration or other alternate
dispute resolution mechanism, investigation, inquiry, judicial, administrative or legislative hearing, whether brought by or in the right of the Company or otherwise, including any and all appeals thereof, whether of a civil, criminal,
administrative, legislative, arbitrative, investigative or other nature or (ii) any inquiry, hearing or investigation that the Employee reasonably believes might lead to the institution of any such action, suit, alternative dispute resolution
mechanism or hearing, whether judicial, administrative or legislative; and 
 (ii) the term “Expenses” means any and all
expenses, including attorneys’ and experts’ fees, court costs and all other expenses, paid or payable in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate,
defend, be a witness in or participate in (including on appeal), any Proceeding.” 
 13. General Provisions. 

(a) Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any
other provision or any other jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction so as to best give effect to the intent of the parties under this Agreement.

understanding among the parties and supersedes and preempts any prior understandings, agreements or representations by or between the parties, written or oral, which may have related to the subject matter hereof in any way. 

(c) Counterparts. This Agreement may be executed in separate counterparts, each of which is deemed to be an original and all of which
taken together constitute one and the same agreement. 
 (d) Success and Assigns. Except as otherwise provided herein, this Agreement
shall bind and inure to the benefit of and be enforceable by the Employee and the Company, and their respective heirs, legal representatives, successors and assigns, including any successor to the Company by means of merger or consolidation;
provided that the rights and obligations of Employee under this Agreement shall not be assignable. The Company is defined to mean an affiliate or subsidiary of the Company, 

(e) Choice of Law. This Agreement shall be governed and construed in accordance with the internal laws of the Commonwealth of
Massachusetts without giving effect to any choice of law or conflict of law provision or rule (whether of the Commonwealth of Massachusetts or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the
Commonwealth of Massachusetts.

expiration of Employee’s employment to the extent that any performance is required following termination or expiration of this Agreement.

 EXHIBIT “A” 

SECTION 3(b): GOALS AND OBJECTIVES 












 AMENDMENT TO EMPLOYMENT AGREEMENT 

THIS AMENDMENT TO EMPLOYMENT AGREEMENT (the “Amendment”) is made and entered into as of the 13th day of October, 2017 (the “Effective Date”), by and between ELISABET DE LOS PINOS, PH.D. of 201 Freeman Street, Unit 6, Brookline, MA 02446 (the “Employee”) and AURA
BIOSCIENCES, INC., a Delaware corporation duly organized under law and having a usual place of business 85 Bolton Street, Cambridge, MA 02140 (the “Company”). 

RECITALS 
 The Company and
Employee entered into that certain Employment Agreement dated January 1, 2015 (the “Agreement”); 
 The Company is
seeking a Series C Equity Financing (the “Series C Financing”) and if the Company is successful in completing a Series C Financing, the Board has approved an increase in the base salary of Employee (contingently and only upon the
initial closing of such Series C Financing) to $360,000 per annum, with such contingent increase being made (i) effective retroactive to January 1, 2017 and (ii) Employee’s continuous employment through the date of the Series C
Financing. 
 The Company and Employee desire to amend Employee’s employment agreement to provide for such contingent increase. 

NOW, THEREFORE, in consideration of the Employee’s continued employment in an executive and management position, the Company desires to
increase the Employee’s base salary and for good and valuable consideration, including the mutual covenants and agreements herein contained, the receipt and legal sufficiency of which are hereby acknowledged, accepted and agreed to, the parties
hereto agree as follows: 
 1. Section 3(a). Base Salary. Section 3(a) is hereby deleted in its entirety and following shall be
inserted as a new Section 3(a): 
 (a) Base Salary. Subject to the provisions of this Agreement, the Company shall pay the
Employee a base salary at the initial rate of Three Hundred Fifteen Thousand ($315,000.00) Dollars calculated on an annual basis (the “Base Salary”), which shall be paid in accordance with the Company’s normal payroll procedures and
policies. Any adjustments to the Base Salary shall be approved by the Board after discussion with the Employee, provided, however, that the Base Salary may not be reduced. All payments made to the Employee pursuant to this Agreement shall be treated
as wages for withholding and employment tax purposes as provided by law, except that reimbursement of expenses will not be so treated to the extent permitted by law. Notwithstanding the foregoing, if the Company successfully completes a
Series C Financing, then Employee’s base salary shall be increased to Three Hundred Sixty Thousand ($360,000.00) Dollars calculated on an annual basis, with such contingent increase being made effective retroactive to January 1, 2017,
as long as Employee is in continuous employment with the Company through the closing date of the Series C Financing and such increase in the Base Salary is paid in a lump sum no later than March 15 of the year following the year in which the
Series C Financing closes. 












 2. Section 3(b). Cash Bonus. Section 3(b) is hereby deleted in its entirety and
following shall be inserted as a new Section 3(b): 
 (b) Cash Bonus. In addition to the Base Salary, the Employee may be
entitled to a bonus of up to Forty (40%) percent of her then Base Salary based upon the successful completion of certain goals and objectives approved by the Board. These goals may relate to the achievement of corporate goals; the achievement of
individual goals or a combination of the same. When the goals are agreed to, they shall be identified on Exhibit “A” and added to this Agreement. The decision of the Board as to whether or not the goals have been achieved and the
amount of the bonus to be awarded, if any, shall be final and binding on the parties. A bonus, if awarded, shall not be added to the Base Salary and, if awarded, will be paid within forty five (45) days after the end of the year with respect to
which the bonus is being awarded. 
 Except as amended hereunder, all other terms and conditions of the Agreement shall remain in full force
and effect. This Amendment may be executed in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument. 












 IN WITNESS WHEREOF, the parties hereto have, executed this Amendment as a document, under
seal, on the date first written above.
