and collectively the “Warrants,” and collectively with the Notes and this Agreement, the “Transaction
Documents”) in accordance with the Investor’s individual allocation as set forth on Schedule I hereto.


 






    	 



    	 



    

 


2. Closing and Delivery of the Notes,
Warrants and Funds

sale of the Notes and Warrants (the “Closing”) shall occur remotely via exchange of documents and signatures
on October 22, 2014 (the “Closing Date”).


 


(b)Delivery. At the Closing, the
Company will deliver to each of the Investors the Note and Warrants to be purchased by such Investor, against receipt by the Company
of the purchase price set forth on Schedule I hereto (the “Purchase Price”).


 


3. Warrants.


 


(a)Issuance. At
the Closing, the Company shall issue the Warrants to the Investors as provided in Section 1. Each Warrant shall be exercisable
at an exercise price of $2.20 per share (the “Exercise Price”), which is the closing price per share of the
Common Stock on the New York Stock Exchange MKT on the day preceding the date hereof, and shall expire on the third anniversary
of the Closing Date.


 


(b)Waiver of Standstill.
The Company hereby waives any rights it may have pursuant to provision 3(e) (the “Standstill”) of that certain
Common Stock Purchase Agreement, dated as of June 11, 2014, between and among the Company and certain of the Investors (the “Common
Stock Purchase Agreement”), to prevent Investors from purchasing and exercising the Warrants. It is understood that the
Standstill otherwise remains in full force and effect.


 


(c)Registration Rights. The
Warrant will contain the same registration rights with respect to the Common Stock underlying the Warrant (the “Warrant
Shares”) as were granted to investors in the Common Stock Purchase Agreement, except that with respect to the Warrant
Shares, the Company agrees to keep the Registration Statement and Prospectus (each as defined in the Common Stock Purchase Agreement)
effective and current, respectively, for three years from the date the Registration Statement was filed, or if earlier, until such
time as the number of Warrant Shares remaining unsold may be sold by Investors within 12 months in open market transactions under
Rule 144.


 


4. Representations, Warranties and
Covenants of the Company. The Company represents and warrants to each Investor that, as of the date hereof:


 


(a)Due Incorporation, Qualification,
etc. The Company is duly formed and validly existing under the laws of California, with full power and authority to conduct
its business as it is currently being conducted and to own its assets, and has secured any other authorizations, approvals, permits

(b)Authority. The execution,
delivery and performance by the Company of each Transaction Document to be executed by the Company and the consummation of the
transactions contemplated thereby are within the power of the Company and have been duly authorized by all necessary actions on
the part of the Company.


 


(c)Amendment of Rights Plan.
The Company agrees to amend promptly its existing shareholder rights plan, dated as of March 22, 1999, between the Company and
American Stock Transfer & Trust Company, as rights agent, as amended by the first amendment dated as of March 12, 2009 (the
“Rights Plan”) so that the issuance and subsequent exercise of the Warrants does not activate any rights issued
to the Company’s shareholders pursuant to the Rights Plan.


 


(d)No Approvals. No consent
or authorization of, filing with, notice to or other act by, or in respect of, any governmental authority or any other person is
required in order for the Company to execute, deliver, or perform any of its obligations under the Notes or Warrants.

and delivery of the Notes and Warrants and the consummation by the Company of the transactions contemplated hereby and thereby
do not and will not (a) violate any provision of the Company's organizational documents; (b) violate any law or order applicable
to the Company or by which any of its properties or assets may be bound; or (c) constitute a default under any material agreement
or contract by which the Company may be bound.


 


(f)Enforceability. Each of
the Note and Warrant is a valid, legal and binding obligation of the Company, enforceable against it in accordance with their terms
except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting
the enforcement of creditors' rights generally and by general equitable principles (whether enforcement is sought by proceedings
in equity or at law).


 


(g)Reservation of Shares.
The Company shall at all times reserve and keep available out of its authorized but unissued Common Stock, solely for the purpose
of issuance upon the exercise of the Warrant, the maximum number of Warrant Shares issuable upon the exercise thereof. The Company
shall take all such actions as may be necessary or appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of Common Stock upon the exercise of the Warrant.


 


5. Representations, Warranties and
Covenants of Investors. Each Investor, for that Investor alone, represents and warrants to the Company as follows:

laws and, therefore, cannot be resold unless they are registered under the Securities Act and applicable state securities laws
or unless an exemption from such registration requirements is available. Such Investor is aware that the Company is under no obligation
to effect any such registration with respect to the Notes or Warrants or to file for or comply with any exemption from registration.
Such Investor has not been formed solely for the purpose of making this investment and is purchasing the Notes and Warrants to
be acquired by such Investor hereunder for its own account for investment, not as a nominee or agent, and not with a view to, or
for resale in connection with, the distribution thereof.

PROMISSORY NOTE


 





	$[       ]	October 22, 2014
	 	San Francisco, California










 


FOR VALUE RECEIVED, AMERICAN SHARED HOSPITAL
SERVICES, a California corporation (the “Company”) promises to pay to [      ] (the “Investor”),
or his registered assigns, in lawful money of the United States of America the principal sum of [      ] US dollars ($[      ]), or such
lesser amount as shall equal the outstanding principal amount hereof, together with simple interest from the date of this Note
on the unpaid principal balance at a rate equal to 15% per annum, computed on the basis of a 360-day year of twelve 30-day months.
All unpaid principal, together with any then unpaid and accrued interest and other amounts payable hereunder, shall be due and
payable on October 22, 2017 (the “Maturity Date”). This Note is one of the “Notes” issued pursuant
to the Note and Warrant Purchase Agreement of even date herewith (the “Note and Warrant Purchase Agreement”)
between the Company and the Investors (as defined therein).


 


The following is a statement of the rights
of Investor and the conditions to which this Note is subject, and to which Investor, by the acceptance of this Note, agrees:


 


1.Interest. The Company
promises to pay interest on the principal amount of this Note at the rate per annum described above. Interest on the Note will
accrue from the most recent date to which interest has been paid; or, if no interest has been paid, from October 22, 2014. The
Company will pay interest monthly on the 22nd of each month (each an “Interest Payment Date”), commencing with
the first Interest Payment Date next succeeding the date hereof, and at the Maturity Date; provided that any payment of
interest to be made on any Interest Payment Date or on the Maturity Date that is not a Business Day shall be made on the next succeeding
Business Day with the same force and effect as if made on such Interest Payment Date or the Maturity Date, as the case may be,
and no additional interest shall accrue as a result of such delayed payment. The term “Business Day” means any
day, that is not a Saturday or Sunday, and that is not a day on which banking institutions in New York City are generally authorized,
obligated or by law or executive order to be closed.


 






    	 



    	 



    

 


2.Prepayment.


 


(a)Optional Prepayment. The

2015.


 


(b)Mandatory Prepayment.
The Company shall, within five (5) days following the consummation of the Fifth Milestone Payment (as defined below), prepay the
Outstanding Balance of this Note in whole without penalty or premium. For purposes of this Section 2(b), the term “Fifth
Milestone Payment” shall mean payment by a third party financial institution to Mevion Medical Systems, Inc. (“Mevion”)
of the fifth milestone payment referenced in that certain System Build Agreement dated as of February 26, 2007 by and between the
Company and Mevion and $2,000,000 to reimburse the Company for the third and fourth milestone payments.


 


(c)Repayment upon Mevion IPO.
In the event of the initial public offering of the common stock of Mevion (the “Mevion IPO”), if this Note has
not previously been fully repaid, then, upon receipt of a written request from an Investor, the Company shall sell some or all
of its shares of Mevion’s common stock (the “Mevion Shares”) and promptly use the proceeds of such sale
to prepay the Outstanding Balance of this Note in whole or in part without penalty or premium, provided that the Company
shall be under no obligation to sell any Mevion Shares until the Company’s lock-up agreement in connection with the Mevion
IPO has expired. Any such prepayment shall be made on a pro rata basis among the Notes issued pursuant to the Note and Warrant
Purchase Agreement based on the principal amount of each Note then outstanding.


 


3.Events of Default


 


(a)Each of the following shall constitute
an “Event of Default”:


 


(i)Failure to Pay.  The Company
fails to pay (a) any principal amount of this Note when due or (b) interest or any other amount when due and such failure continues

(ii)Breach of Representations,
Warranties or Covenants. Any representation or warranty made or deemed made by the Company in the Note and Warrant Purchase
Agreement is incorrect in any material respect on the date as of which such representation or warranty was made or deemed made.
The Company fails to observe or perform (a) any covenant, condition or agreement contained in the Note and Warrant Purchase Agreement
or (b) any other covenant, obligation, condition or agreement contained in this Note and such failure continues for 30 days after
written notice to the Company.

purpose of effecting any of the foregoing; or

in effect shall be commenced and an order for relief entered or such proceeding shall not be dismissed or discharged within 30
days of commencement.


 


(b)If an Event of Default (other than
an Event of Default specified in clause (iii) or (iv) of Section 3(a) hereof with respect to the Company) shall have occurred and
is continuing, Investors holding at least 50% of the principal amount of the then outstanding Notes may declare the principal of,
and accrued and unpaid interest on the Note to be due and payable by notice in writing to the Company and the same shall become
immediately due and payable.


 


If an Event of Default specified in clause
(iii) or (iv) of Section 3(a) hereof with respect to the Company occurs and is continuing, then the entire outstanding principal
amount of the Note will automatically become due immediately and payable in each and every case without presentment, demand, protest
or further notice, all of which are hereby waived by the Company.

is paid on this Note which is deemed to be in excess of the then legal maximum rate, then that portion of the interest payment
representing an amount in excess of the then legal maximum rate shall be deemed a payment of principal and applied against the

shares of Common Stock or other securities or property (including any money) to which the Holder is entitled, registered or otherwise
placed in, or payable to the order of, the name or names of the Holder as may be directed in writing by the Holder, and shall promptly
deliver such evidence of ownership and any other securities or property (including any money) to the Person or Persons entitled
to receive the same, together with an amount in cash in lieu of any fraction of a share as provided in paragraph ‎5 below.

(e)In lieu of making a cash payment
of the Exercise Price to exercise this Warrant pursuant to paragraph ‎2(a) (but in all other respects in accordance with the
exercise procedure set forth in paragraph ‎2(a)), the Holder may elect to convert this Warrant into shares of Common Stock,
in which event the Company will issue to the Holder the number of shares of Common Stock equal to the amount resulting from the
following equation:


 


X = (A - B) x C where:

A


 


X =the number of shares of
Common Stock issuable upon exercise pursuant to this paragraph ‎2(e);


 


A =the Current Market Price
Per Common Share on the date on which the Holder delivers a Warrant Exercise Notice to the Company pursuant to paragraph ‎2(a);


 


B =the Exercise Price; and


 


C =the number of shares of
Common Stock as to which this Warrant is being exercised pursuant to paragraph ‎2(a).


 


If the foregoing calculation results in
zero or a negative number, then no shares of Common Stock shall be issued upon exercise pursuant to this paragraph ‎2(e).


 


3. Restrictive Legend. Certificates
representing shares of Common Stock issued pursuant to this Warrant shall bear a legend substantially in the form of the legend
set forth on the first page of this Warrant to the extent that and for so long as such legend is required pursuant to applicable
securities laws.


 


4. Reservation of Shares. The Company
hereby agrees that at all times there shall be reserved for issuance and delivery upon exercise of this Warrant such number of
its authorized but unissued shares of Common Stock or other securities of the Company from time to time issuable upon exercise
of this Warrant as will be sufficient to permit the exercise in full of this Warrant. All such shares shall be duly authorized
and, when issued upon such exercise, shall be validly issued, fully paid and non-assessable, free and clear of all liens, security
interests, charges and other encumbrances or restrictions on sale and free and clear of all preemptive rights, in each case except
restrictions on transfer contemplated by paragraph ‎3, to the extent set forth in the Note and Warrant Purchase Agreement and
to the extent created by the Holder.

5. Fractional Shares. No fractional
shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant, and in lieu of delivery of any
such fractional share to which the Holder may be entitled upon any exercise of this Warrant, the Company shall pay to the Holder
an amount in cash equal to such fraction multiplied by the Current Market Price Per Common Share on the Business Day immediately
preceding the date on which the Holder delivers the Warrant Exercise Notice pursuant to paragraph ‎2(a).


 


6. Loss or Destruction of Warrant.
Upon receipt by the Company of evidence satisfactory to it (in the exercise of its reasonable discretion) of the loss, theft, destruction
or mutilation of this Warrant, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver a new Warrant of like tenor
and date.


 


7. Anti-dilution Provisions.


 


(a)Common Stock Dividends,
Subdivisions or Combinations. If the Company shall at any time after the date hereof (A) declare and pay a dividend or make
a distribution on Common Stock payable in Common Stock, (B) subdivide or split the outstanding shares of Common Stock into a greater
number of shares or (C) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares, then in each
such case:


 


(i)the number of Warrant Shares issuable
upon exercise of this Warrant thereafter shall be proportionately adjusted so that the exercise of this Warrant after such event
shall entitle the Holder to receive the aggregate number of shares of Common Stock that such Holder would have been entitled to
receive had such Holder exercised this Warrant immediately prior to such event; and


 


(ii)the Exercise Price thereafter shall
be adjusted to equal the product of the Exercise Price in effect immediately prior to such event multiplied by a fraction 0 the
numerator of which shall be the number of Warrant Shares issuable upon the exercise of this Warrant immediately prior to such event
and 0 the denominator of which shall be the number of Warrant Shares issuable upon the exercise of this Warrant immediately following
such event.


 


Any adjustment made pursuant to this paragraph
‎8(a) shall become effective immediately after the applicable record date in the case of a dividend or distribution and immediately
after the applicable effective date in the case of a subdivision, split, combination or reclassification.


 






    	6



    	 



    

 


(b)Certain Issuances of Common
Stock or Convertible Securities. If the Company shall issue or sell any shares of Common Stock (or options, rights, warrants
or other securities convertible into or exchangeable or exercisable for shares of Common Stock (collectively, “convertible
securities”)) (other than Excluded Securities) without consideration or at an Aggregate Offering Price that is less than
the Current Market Price Per Common Share on the last trading day preceding the date of the agreement on pricing such shares of
Common Stock (or such convertible securities), then in each such case:


 


(i)the number of Warrant Shares issuable
upon exercise of this Warrant thereafter shall be adjusted to equal the product of the number of Warrant Shares issuable upon the
exercise of this Warrant immediately prior to such record date (or issuance or sale date, as applicable) multiplied by a fraction
0 the numerator of which shall be the sum of (x) the number of shares of Common Stock outstanding on such date and (y) the number
of additional shares of Common Stock issued (or into which convertible securities may be exercised or converted) and 0 the denominator
of which shall be the sum of 0 the number of shares of Common Stock outstanding on such date and 0 the number of shares of Common
Stock that the aggregate consideration for the total number of such additional shares of Common Stock so issued (or into which
convertible securities may be exercised or converted) would purchase at a price per share equal to the Current Market Price Per
Common Share on such record date (or issuance or sale date, as applicable); and


 


(ii)the Exercise Price thereafter shall
be adjusted to equal the product of the Exercise Price in effect immediately prior to such record date (or issuance or sale date,
as applicable) multiplied by a fraction (A) the numerator of which shall be the number of Warrant Shares issuable upon the exercise
of this Warrant immediately prior to such record date (or issuance or sale date, as applicable) and (B) the denominator of which
shall be the number of Warrant Shares issuable upon the exercise of this Warrant immediately following such record date (or issuance
or sale date, as applicable).


 


Any adjustment made pursuant to this paragraph
8(b) shall become effective immediately after the applicable record date (or, if no record date is used, after the issuance or
sale date).


 






    	7



    	 



    

 


(c)Consolidation, Merger or
Sale of Assets. In the event of any consolidation of the Company with, or merger of the Company into, any other Person, any
merger of another Person into the Company (other than a merger which does not result in any reclassification, conversion, exchange
or cancellation of outstanding shares of Common Stock) or any sale or transfer of all or substantially all of the assets of the
Company to the Person formed by such consolidation or resulting from such merger, as the case may be, the Holder shall have the
right thereafter to exercise this Warrant for the kind and amount of securities, cash and/or other property receivable upon such
consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock for which this Warrant may have been
exercised immediately prior to such consolidation, merger, sale or transfer. In determining the kind and amount of securities,
cash and/or other property receivable upon such consolidation, merger, sale or transfer, if the holders of Common Stock have the
right to elect as to the consideration to be received upon the consummation of such consolidation, merger, sale or transfer, then
the consideration that the Holder shall be entitled to receive upon exercise shall be deemed to be the kind and amount of consideration
received by the majority of all holders of Common Stock that affirmatively make an election (or of all such holders if none make
an election). Adjustments for events subsequent to the effective date of such a consolidation, merger, sale or transfer of assets
shall be as nearly equivalent as may be practicable to the adjustments provided for in this Warrant. In any such event, effective
provisions shall be made in the certificate or articles of incorporation of the resulting or surviving corporation, in any contract
of sale, merger, conveyance, lease, transfer or otherwise so that the provisions set forth herein for the protection of the rights
of the Holder shall thereafter continue to be applicable; and any such resulting or surviving corporation shall expressly assume
the obligation to deliver, upon exercise, such shares of stock, other securities, cash and property.


 


(d)Certain Determinations.
For purposes of any computation of any adjustment required under this paragraph 8:


 


(i)adjustments shall be made successively
whenever any event giving rise to such an adjustment shall occur;


 


(ii)if any portion of any consideration
to be received by the Company in a transaction giving rise to such an adjustment shall be in a form other than cash, the fair market
value of such non-cash consideration shall be utilized in such computation. Such fair market value shall be determined by the Board
of Directors; provided that if the Holder shall object to any such determination, the Board of Directors shall retain an
independent appraiser reasonably satisfactory to the Holder to determine such fair market value. The expense of such independent
appraiser shall be shared equally by the Company and the Holder. The Holder shall be notified promptly of any consideration other
than cash to be received by the Company and furnished with a description of the consideration and the fair market value thereof,
as determined in accordance with the foregoing provisions;


 


(iii)such calculations shall be made to
the nearest one-tenth of a cent or to the nearest hundredth of a share, as the case may be; and


 


(iv)no adjustment in the Exercise Price
or the number of Warrant Shares issuable upon exercise of the Warrant, as the case may be, shall be required if the amount of such
adjustment would be less than one-tenth of a cent or hundredth of a share, as the case may be; provided that any adjustments
which by reason of this paragraph ‎8(e)(iv) are not required to be made shall be carried forward and taken into account in
any subsequent adjustment.


 






    	8



    	 



    

 


(e)Certificates as to Adjustments.
Upon the occurrence of each adjustment to the Exercise Price and/or the number of Warrant Shares issuable upon exercise of this
Warrant, the Company shall promptly compute such adjustment in accordance with the terms hereof and furnish to the Holder a certificate
setting forth such adjustment and showing in reasonable detail the facts upon which such adjustment is based.


 


(f)Notices. In the event
that the Company shall propose at any time to effect any of the events described in paragraphs ‎(a) through ‎(e) above
that would result in an adjustment to the Exercise Price, the number of Warrant Shares issuable upon exercise of this Warrant or
a change in the type of securities or property to be delivered upon exercise of this Warrant, the Company shall send notice to
the Holder in the manner set forth in paragraph ‎9. In the case of a dividend or other distribution, such notice shall be sent
at least 10 days prior to the applicable record date and shall specify such record date and the date on which such dividend or
other distribution is to be made. In any other case, such notice shall be sent at least 15 days prior to the effective date of
any such event and shall specify such effective date. In all cases, such notice shall specify such event in reasonable detail,
including the effect on the Exercise Price and the number, kind or class of securities or other property issuable upon exercise
of this Warrant. Failure to furnish any certificate pursuant to paragraph 7(e) or to give any notice pursuant to this paragraph
7(f), or any defect in any such certificate or notice, shall not affect the legality or the validity of the adjustment of the Exercise
Price and/or the number of securities, cash and/or other property issuable upon exercise of this Warrant, or any transaction giving
rise thereto.


 


8. Notices. Any notice, demand
or delivery authorized by this Warrant shall be in writing and shall be given to the Holder or the Company, as the case may be,
at the respective addresses of the parties as set forth in the Note and Warrant Purchase Agreement, or such other address (or facsimile
number) as shall have been furnished to the party giving or making such notice, demand or delivery. Each such notice, demand or
delivery shall be deemed received on the date of receipt by the recipient thereof if received prior to 5:00 p.m. in the place of
receipt and such day is a Business Day. Otherwise, any such notice, demand or delivery shall be deemed not to have been received
until the next succeeding Business Day.


 


9. Rights of the Holder. Prior
to any exercise of this Warrant, the Holder shall not, by virtue hereof, be entitled to any rights of a shareholder of the Company,
including, without limitation, the right to vote, to receive dividends or other distributions, to exercise any preemptive right
or to receive any notice of meetings of shareholders or any notice of any proceedings of the Company except as may be specifically
provided for herein.

10.GOVERNING LAW. THIS WARRANT
AND ALL RIGHTS ARISING HEREUNDER SHALL BE CONSTRUED AND DETERMINED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF CALIFORNIA,
AND THE PERFORMANCE THEREOF SHALL BE GOVERNED AND ENFORCED IN ACCORDANCE WITH SUCH LAWS. 


 


11.Amendments; Waivers. Any provision
of this Warrant may be amended or waived if, and only if, such amendment or waiver is in writing and signed, in the case of an
amendment, by the Holder and the Company, or in the case of a waiver, by the party against whom the waiver is to be effective.
No failure or delay by either party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor
shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right,
power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided
by law.
