EX-10.24



 Exhibit 10.24 

This instrument and the rights and obligations evidenced hereby and any security interests or other liens securing such obligations are subordinate in the
manner and to the extent set forth in that certain Subordination and Intercreditor Agreement dated as of August 19, 2014 (as amended, restated, superseded, replaced, succeeded, substituted, supplemented or otherwise modified from time to time
in accordance with its terms, the “Subordination Agreement”) among Mevion Medical Systems, Inc. (“Borrower”), Life Sciences Alternative Funding LLC (the “Senior Lender”), and the other parties thereto to all obligations
owing by Borrower to Senior Lender (including interest, expenses and fees) as described in the Subordination Agreement. Each holder of this instrument, by its acceptance hereof, irrevocably agrees to be bound by the provisions of the Subordination
Agreement. 
 NOTE AND WARRANT PURCHASE AGREEMENT 

This NOTE AND WARRANT PURCHASE AGREEMENT (this “Agreement”), dated August 19, 2014, is by and among Mevion Medical
Systems, Inc., a Delaware corporation (the “Company”), and the persons listed on Schedule I hereto (individually, an “Investor” and collectively, the “Investors”). 

The Company and the Investors hereby agree as follows: 

1. The Notes. The Company has authorized the issuance and sale, in accordance with the terms hereof, of the Company’s convertible promissory notes
in the original aggregate principal amount of up to $7,500,000 (the “Maximum Allocation”) to the Investors (each, a “Note”, and collectively, the “Notes”). Each Note, with the exception of the Note
being issued to CHL Medical Partners III Side Fund, L.P. (the “Side Fund”), will be substantially in the form attached hereto as Exhibit A, and will be convertible into shares of the equity securities sold in connection with
the Next Qualified Financing (as defined in the Note) (the “Conversion Shares”), in accordance with the terms of such Note. The Note being issued to the Side Fund will be substantially in the form attached hereto as Exhibit
B. The Notes shall be subordinate to the indebtedness of the Company to Life Sciences Alternative Funding LLC (“LSAF”) pursuant to that certain Loan Agreement, dated as of June 25, 2013, as the same may be amended, restated
or otherwise modified from time to time. The Maximum Allocation shall be allocated to the Investors proportionally based on the number of shares of preferred stock of the Company held by each Investor as of the date of this Agreement (determined on
an as-converted to common stock basis) (the “Pro Rata Allocation”). 
 2. Purchase and Sale of Notes. The Company agrees to issue
and sell to the Investors, and, subject to and in reliance upon the representations, warranties, terms and conditions contained herein, each Investor, severally and not jointly, agrees to purchase a Note in the principal amount set forth opposite
such Investor’s name on Schedule I hereto. The purchase and sale shall take place at a closing (the “Closing”) to be held remotely via the exchange of documents, on the date hereof, or at such time or place as may
be mutually agreed upon by the Company and the Investors. At the Closing, the Company will deliver a Note to each Investor against payment of the purchase price by such Investor by check payable to the Company or wire in immediately available United
States funds. 

  








 3. Bridge Warrants. At the Closing the Company shall issue to each Investor that purchases the full amount
of its Second Pro Rata Allocation (as defined below) (a “Super Pro Rata Investor”), a Bridge Warrant, in substantially the form attached hereto as Exhibit C (the “Bridge Warrant”). 

(a) In the event that not all Investors purchase their respective Pro Rata Allocation, then each Investor that purchases at least its Pro Rata
Allocation will be entitled to subscribe for its pro rata portion (as based on its Pro Rata Allocation) of the remaining Maximum Allocation (the “Second Pro Rata Allocation”). Each Investor that purchases its full Pro Rata
Allocation and Second Pro Rata Allocation shall be deemed a “Super Pro Rata Investor”. Schedule I will indicate whether or not an Investor is a Super Pro Rata Investor. 

(b) Each Bridge Warrant will represent the right to purchase that number of Conversion Shares as is equal to fifty percent (50%) of the
principal amount of the Note purchased by the Super Pro Rata Investor divided by the Conversion Price (as defined in the Notes). The Company and the Investors, as a result of arm’s length bargaining, agree that (i) neither the Investors
nor any of their partners, members, stockholders, employees or affiliates has rendered or agreed to render any services to the Company in connection with this Agreement or the issuance of the Notes and the Bridge Warrants; (ii) the Notes and
the Bridge Warrants are not being issued as compensation; and (iii) the assumed price at which the Notes would be issued if they were issued apart from the Bridge Warrants is 99% of the principal amount of the Notes. 

4. Series E Preferred Stock Warrants. Each Super Pro Rata Investor who holds a warrant or warrants to purchase shares of the Company’s Series E
Preferred Stock (the “Series E Warrants”) shall be entitled to surrender its Series E Warrants to the Company at the closing of the Next Qualified Financing in exchange for a Bridge Warrant having an equivalent value to the Series E
Warrants being exchanged. The value of a Series E Warrant will be calculated by multiplying the number of shares of Series E Preferred Stock issuable thereunder by the exercise price of such Series E Warrant. 

5. Use of Proceeds. The proceeds of the sale and issuance of the Notes and Bridge Warrants shall be used for general corporate purposes. 

6. Representations and Warranties of the Company. The Company hereby represents and warrants to the Investors as of the Closing: 

(a) Organization and Corporate Power. The Company is an entity duly organized, validly existing and in good standing under the laws of
its jurisdiction of organization and is duly qualified, licensed or registered to do business as a foreign corporation in each jurisdiction in which the failure to be so qualified, licensed or registered would have a Material Adverse Effect (as
defined herein). For purposes of this Agreement, the term “Material Adverse Effect” means any change or effect that is materially adverse to the properties, assets, business, financial condition or operations of the Company. The
Company has all required corporate power and authority to own, lease and operate its properties and carry on its business as presently conducted, and to enter into and perform its obligations under this Agreement, the Notes, the Bridge Warrants, and
all other documents, agreements or instruments entered into or delivered in connection therewith (together, the “Transaction Documents”). 

  








 (b) Enforceability and Authorization. Each of the Transaction Documents is a legal, valid
and binding obligation of the Company, enforceable in accordance with its terms. The execution, delivery and performance of the Transaction Documents have been duly authorized by all necessary corporate or other action of the Company. 

(c) Non-Contravention. The execution, delivery and performance of the Transaction Documents executed by the Company and the performance
and consummation of the transactions contemplated thereby do not and will not (i) violate the Company’s Certificate of Incorporation and Bylaws (each, as amended, the “Charter Documents”) or any material judgment, order,
writ, decree, statute, rule or regulation applicable to the Company; (ii) violate any provision of, or result in the breach or the acceleration of, or entitle any other person or entity to accelerate (whether after the giving of notice or lapse
of time or both), any material mortgage, indenture, agreement, instrument or contract to which the Company is a party or by which it is bound; or (iii) result in the creation or imposition of any lien upon any property, asset or revenue of the
Company or the suspension, revocation, impairment, forfeiture, or nonrenewal of any material permit, license, authorization or approval applicable to the Company, its business or operations, or any of its assets or properties. 

(d) Approvals. No consent, approval, order or authorization of, or registration, declaration or filing with, any governmental authority
or other person (including without limitation, the stockholders of any person) is required in connection with the execution and delivery of the Transaction Documents executed by the Company and the performance and consummation of the transactions
contemplated thereby, other than such as have been obtained and remain in full force and effect and other than such qualifications or filings under applicable securities laws as may be required in connection with the transaction contemplated by the
Transaction Documents. 
 (e) No Violation or Default. The Company is not in violation of or in default with respect to (i) its
Charter Documents or any material judgment, order, writ, decree, statute, rule or regulation applicable to the Company; or (ii) any material mortgage, indenture, agreement, instrument or contract to which the Company is a party or by which it
is bound (nor is there any waiver in effect, which, if not in effect, would result in such violation or default). 
 (f)
Capitalization. The authorized capital of the Company consists, immediately prior to the Closing, of: 
 (i) 9,000,000 shares of
common stock, $0.001 par value per share (the “Common Stock”), 1,759,458 shares of which are issued and outstanding immediately prior to the Closing. All of the outstanding shares of Common Stock have been duly authorized, are fully
paid and non-assessable and were issued in compliance with all applicable federal and state securities laws. 
 (ii) 9,760,039 shares of
Preferred Stock, of which, immediately prior to the Closing, 72,463 shares have been designated Series A Preferred Stock, $0.001 par value per share, 72,463 shares of which are issued and outstanding; of which 118,595 shares have been


  








 
designated Series B Preferred Stock, $0.001 par value per share, 90,293 shares of which are issued and outstanding; 160,925 shares have been designated Series C Preferred Stock, $0.001 par value
per share, 135,999 shares of which are issued and outstanding; 2,915,442 shares have been designated Series D Preferred Stock, $0.001 par value per share, 2,769,670 shares of which are issued and outstanding; 994,614 shares have been designated

(iii) Warrants to purchase an aggregate of 170,766 shares of Series D-1 Preferred Stock, and warrants to purchase an aggregate of 65,517
shares of Series E Preferred Stock. 
 (iv) The Company has reserved 1,335,902 shares of Common Stock for issuance to officers,
directors, employees and consultants of the Company pursuant to its 2005 Stock Option and Incentive Plan duly adopted by the Board of Directors and approved by the Company’s stockholders (the “Stock Plan”). Of such reserved
shares of Common Stock, 40,950 shares have been issued pursuant to restricted stock purchase agreements, options to purchase 1,179,274 shares have been granted and are currently outstanding or exercised, and 112,678 shares of
Common Stock remain available for issuance to officers, directors, employees and consultants pursuant to the Stock Plan. 
 (g) Valid
Issuance. The Notes and the Bridge Warrants, when issued, sold and delivered in accordance with the terms of this Agreement, will be duly authorized, validly issued and non-assessable. Based in part on the representations made by the Investors
in Section 7, the offer and sale of the Notes and Warrants are exempt from the registration and prospectus delivery requirements of the Securities Act of 1933, as amended (the “Securities Act”) and the securities
registration and qualification requirements of the currently effective provisions of the securities law of the state in which the Investor is resident. 

7. Representations and Warranties of the Investors. Each of the Investors, severally and not jointly, represents and warrants as follows: 

(a) Such Investor confirms that it has full power and authority and has taken all required action necessary to permit it to execute and deliver
and to carry out the terms of this Agreement and the other Transaction Documents to which it is a party. 
 (b) Such Investor represents
that it is such Investor’s present intention to acquire its Note and Bridge Warrant, if applicable, for its own account and that such Note and Bridge Warrant, if applicable, are being or will be acquired by it for the purpose of investment and
not with a view to distribution. Such Investor agrees that it will not sell or transfer its Note and Bridge Warrant, if applicable, without registration under applicable federal and state securities laws, or the availability of exemptions therefrom.
Such Investor agrees that the Note and Bridge Warrant, if applicable, will bear a restrictive legend stating that Note and Bridge Warrant, if applicable, have not been registered under applicable federal and state securities laws and referring to
restrictions on their transferability and sale. 







 (c) Such Investor acknowledges that it currently has, and had immediately prior to its receipt of
the offer of sale from the Company, such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of this investment and further acknowledges that it is able to bear the economic risk of this
investment. During the course of this transaction and prior to the sale to the Investors of the Notes and Bridge Warrants, if applicable, hereunder, such Investor acknowledges that it has had the opportunity to ask questions of, and receive answers
from, management of the Company concerning the terms and conditions of this investment and to obtain any additional information of the same kind that is specified in Rule 502 of Regulation D of the Securities Act, or that is necessary to
verify the accuracy of the other information obtained. Such Investor acknowledges that it has received such information as it deems necessary to enable it to make its investment decision. 

(d) Such Investor represents that it is an “accredited investor” as defined by the rules and regulations of the Securities and
Exchange Commission pursuant to the Securities Act. 
 (e) Each Investor maintains its permanent domicile in the state or country set forth
below its name in Schedule I. 
 8. Tax Treatment. The parties hereto hereby acknowledge and agree that, notwithstanding the title of the
Notes, for United States federal and state income tax purposes the Notes are, and at all times have been, more properly characterized as equity. Accordingly, the parties agree to treat the Notes as equity for all United States federal and state
income tax purposes (including, without limitation, on their respective tax returns or other informational statements). For the avoidance of doubt, the Company hereby agrees that, with regard specifically to the rule set forth in Section 385 of
the Internal Revenue Code of 1986, as amended, the Company will treat the Notes as equity as of the time of issuance. Notwithstanding the foregoing, this Section 8 shall only affect the tax treatment of the Notes and shall not affect the
validity of the obligations thereunder for any other purpose, including (without limitation) in any legal proceeding seeking to enforce rights under the Notes, or in the context of a reorganization or liquidation of the Company under the United
States Bankruptcy Code (11 U.S.C. et seq). 
 9. Defaults and Remedies. 

(a) Events of Default. The following events shall be considered Events of Default with respect to each Note: 

(i) The Company shall default in the payment of any part of the principal or unpaid accrued interest on the Notes or any other outstanding
indebtedness when such payments are due; 
 (ii) The Company shall fail to observe or perform any other covenant, material obligation,
condition or agreement contained in the Transaction Documents; 
 (iii) Any representation, warranty, certificate, or other statement made
or furnished by or on behalf of the Company to the Investors in writing in connection with the Transaction Documents, or as an inducement to the Investors to enter into the Transaction Documents, shall be false, incorrect, incomplete or misleading
in any material respect when made or furnished; 

  








 (iv) The Company shall (a) make an assignment for the benefit of any of its creditors;
(b) admit in writing its inability to pay its debts as they become due; (c) file a voluntary petition for bankruptcy; (d) file any petition or answer seeking for itself any reorganization, arrangement, composition, readjustment,
dissolution or similar relief under any present or future statute, law or regulation; (e) file any answer admitting the material allegations of a petition filed against the Company in any such proceeding; (f) seek or consent to or
acquiesce in the appointment of any custodian, trustee, receiver or liquidator of the Company, or of all or any substantial part of the properties of the Company; (g) actually be dissolved or liquidated or its respective directors or majority
stockholders shall take any action looking to the dissolution or liquidation of the Company; or (h) take any action for the purpose of effecting any of the foregoing; or 

(v) Within thirty (30) days after the commencement of any proceeding against the Company seeking any bankruptcy reorganization,
arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation, such proceeding shall not have been dismissed, or within thirty (30) days after the appointment without
the consent or acquiescence of the Company of any trustee, receiver or liquidator of the Company or of all or any substantial part of the properties of the Company, such appointment shall not have been vacated. 

(b) Remedies. If the Company fails to cure an Event of Default within thirty (30) days of the commencement of such Event of
Default, (i) in the event of an Event of Default specified in Section 8(a)(i), Section 8(a)(ii) or Section 8(a)(iii), at the option and upon the declaration of the holders of at least a majority of the
principal outstanding under the Notes (the “Required Vote”), and (ii) in the event of an Event of Default specified in Section 8(a)(iv) or Section 8(a)(v), automatically, the entire unpaid principal and
accrued and unpaid interest on all outstanding Notes shall, without presentment, demand, protest, or notice of any kind, all of which are hereby expressly waived, be forthwith due and payable, and the holders of Notes may enforce payment of all
amounts due and owing under such Notes and exercise any and all other remedies granted to them at law, in equity or otherwise. 
 10. No Impairment.
The Company will not, by amendment of its Charter Documents, or through reorganization, consolidation, merger, dissolution, issue or sale of securities, sale of assets or any other voluntary action, willfully avoid or seek to avoid the observance or
performance of any of the terms of the Transaction Documents, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such action as may be necessary or appropriate in order to protect the rights of
the Investors under the Transaction Documents against wrongful impairment. 
 11. Amendments, Waivers, Etc. It is intended that the Investors will
act in concert with respect to all actions taken regarding the Transaction Documents. To accomplish such result, the Investors hereby agree that the Transaction Documents, or any term hereof or thereof may be amended, waived, discharged or
terminated by a written instrument signed by the holders of Notes representing the Required Vote, provided, however, that no amendments shall be made to the Transaction Documents without the consent of each of the Investors, unless all Note
holders are treated in the same manner, provided, further, that no amendments shall be made to this Section 11, without the consent of each of the Investors. 







 12. Choice of Law. It is the intention of the parties that the internal laws, and not the laws of
conflicts, of the State of Delaware should govern the enforceability and validity of the Transaction Documents, the construction of their terms and the interpretation of the rights and duties of the parties pursuant to the relationships among them
contemplated herein and therein, whether or not such rights and duties arise directly under the Transaction Documents. 
 13. Fees and Expenses. The
Company will pay the aggregate out of pocket costs, fees and expenses incurred by the Investors in connection with this financing. 
 14. Parties in
Interest. Subject to the limitations in Section 15 below, the terms and provisions of the Transaction Documents shall be binding upon and inure to the benefit of, and be enforceable by, the respective successors and assigns of the
parties hereto. The Transaction Documents shall not run to the benefit of or be enforceable by any person other than a party to the Transaction Documents and its successors and assigns. 

15. Assignment by the Company. The rights, interests or obligations of the Transaction Documents may not be assigned by operation of law or otherwise,
in whole or in part, by the Company without the prior written consent of the holders of Notes representing the Required Vote. 
 16. Survival of
Representations and Warranties. All representations and warranties made in the Transaction Documents, or any other instrument or document delivered in connection herewith or therewith, shall survive the execution and delivery hereof or thereof.

 17. Severability. The invalidity or unenforceability of any provision hereof shall in no way affect the validity or enforceability of any other
provision. 
 18. Headings. The headings of the Sections and paragraphs of the Transaction Documents have been inserted for convenience and reference
only and do not constitute a part of the Transaction Documents. 
 19. Notices. All notices, requests, demands and other communications provided for
hereunder shall be in writing (including facsimile and email communications) and mailed, emailed, faxed or delivered: 
 If to an Investor,
at the address set forth in Schedule I attached hereto or at such other address as to which such Investor may inform the other parties in writing in compliance with the terms of this Section 19.
