WHEREAS, pursuant to that certain Common Stock Repurchase Agreement, dated of even date herewith, between the Company and the Initial Warrant

Purchase Agreement. 
 WHEREAS, in connection with the Common Stock Repurchase Agreement, the Initial Warrant Holder and the Company desire

 NOW, THEREFORE, in consideration of the covenants and provisions set forth herein, the
parties agree that Original Warrant be amended and restated in its entirety as set forth herein. 
 THIS IS TO CERTIFY THAT, the Initial

Warrant. 
 “Warrant Shares” shall mean the Warrant Shares as adjusted from time to time pursuant to the terms of this

of the foregoing clauses (i) and (ii). 
 2. Exercise Of Warrant.  

2.1 Method of Exercise.  

(a) Subject to and upon all of the terms and conditions set forth in this Warrant, the Holder may exercise this Warrant, in whole or in part
with respect to any Warrant Shares, at any time and from time to time during the period commencing on the Initial Exercise Date and ending on the earlier of (i) the Expiration Date, or (ii) the termination of this Warrant pursuant to

all or such portion of such aggregate Exercise Price by electing not to receive all of such Warrant Shares otherwise issuable upon such exercise but only to receive that number of such Warrant Shares as shall be determined in accordance with the
following formula:

A 
  

			
	Where:	  	 X  = the number of Warrant Shares to be issued to the Holder pursuant to this
Section 2.1(b)

applicable Exercise Date

Stock constituting such Warrant Shares

Stock constituting such Warrant Shares

 The Holder may elect to make payment of all or any portion of such aggregate Exercise Price pursuant to, and in the manner set
forth in, this Section 2.1(b) by surrendering this Warrant to the Company at its principal office, together with (a) a properly completed and duly executed net issue exercise election, in the form attached hereto, which net issue exercise
election shall specify the number of Warrant Shares for which this Warrant is then being exercised (which shall include the number of Warrant Shares to be surrendered as payment therefore), (b) if requested by the Company, a duly executed instrument
or certificate, in form and substance satisfactory to the Company, pursuant to which the Holder makes such representations and warranties to the Company, and provides or confirms such information concerning the Holder, as the Company may reasonably
request (including, without limitation, such representations and warranties and such information as may be required in order to confirm compliance with applicable securities laws), (c) if the Company shall have in place and the Holder is not already
a party to a stockholder’s, voting, or other like agreement of the Company, an instrument of accession to such agreement or agreements in substantially the form requested by the Company, and (d) if applicable, the payment of any transfer
taxes required to be paid by the Holder pursuant to Section 2.7 hereof. Payment of such transfer taxes shall be made in cash, by money order, certified or bank cashier’s check or wire transfer (in each case in lawful currency of the United
States of America). Any such exercise pursuant to this Section 2.1(b) may be made contemporaneous with, and contingent upon, the applicable Change of Control or Initial Public Offering.

 2.2 Effectiveness of Exercise; Ownership. Each exercise of this Warrant
by the Holder shall be deemed to have been effected immediately prior to the close of business on the date upon which all of the requirements of Section 2.1(a) or 2.1(b) hereof, as applicable, with respect to such exercise shall have been
complied with in full (each such date, an “Exercise Date”). On the applicable Exercise Date with respect to any exercise of this Warrant by the Holder, the Company shall be deemed to have issued to the Holder, and the Holder
shall be deemed to have become the holder of record and legal owner of, the number of Warrant Shares being purchased upon such exercise of this Warrant, notwithstanding that the stock transfer books of the Company shall then be closed or that
certificates representing such number of Warrant Shares being purchased shall not then be actually delivered to the Holder. 
 2.3
Delivery of Stock Certificates on Exercise. As soon as practicable after the exercise of this Warrant, and in any event within thirty (30) days thereafter, the Company, at its expense, will cause to be issued in the name of and
delivered to the Holder, or as the Holder may direct (upon payment by the Holder of any applicable transfer taxes as required by Section 2.7 hereof and subject to, in all cases, the provisions of Section 9 hereof), a certificate or
certificates for the number of Warrant Shares purchased by the Holder on such exercise, plus, in lieu of any fractional share to which the Holder would otherwise be entitled, cash equal to such fraction multiplied by the Fair Market Value. 

2.4 Shares To Be Fully Paid and Nonassessable. All Warrant Shares issued upon the exercise of this Warrant shall be
validly issued, fully paid and nonassessable, free of all liens, taxes, charges and other encumbrances or restrictions on sale (other than those set forth herein, including restrictions under the stockholders agreements referenced in
Section 2.1) and free and clear of all preemptive rights and, assuming no change in the federal and state securities laws and assuming the Holder exercising the Warrants is an accredited investor, will be issued in compliance with all
applicable federal and state securities laws. 
 2.5 Fractional Shares. No fractional shares of Stock or scrip
representing fractional shares of Stock shall be issued upon the exercise of this Warrant. With respect to any fraction of a share of Stock called for upon any exercise hereof, the Company shall make a cash payment to the Holder as set forth in
Section 2.3 hereof. 
 2.6 Issuance of New Warrants; Company Acknowledgment. Upon any partial exercise of this
Warrant, the Company, at its expense, will forthwith issue and deliver to the Holder a new warrant or warrants of like tenor, registered in the name of the Holder, and exercisable, in the aggregate, for the balance of the Warrant Shares. Moreover,
the Company shall, at the time of any exercise of this Warrant, upon the request of the Holder, acknowledge in writing its continuing obligation to afford to the Holder any rights to which the Holder shall continue to be entitled after such exercise
in accordance with the provisions of this Warrant; provided, however, that if the Holder shall fail to make any such request, such failure shall not affect the continuing obligation of the Company to afford to the Holder any such
rights. 

  
 5 

 2.7 Payment of Taxes and Expenses. The Holder shall be required to pay
any tax which may be payable in respect of any transfer involved in the issuance of, and the preparation and delivery of certificates (if applicable) representing, (i) any Warrant Shares purchased upon exercise of this Warrant and issued in a
name other than that or the Holders and/or (ii) new or replacement warrants in a name other than that of the Holder, and, until the payment of such tax, the Company shall not be required to issue or cause to be issued any such purchased Warrant
Shares or any such new or replacement warrants, and the Company shall also not be required to prepare and deliver, or to cause to be prepared and delivered, certificates representing any such purchased Warrant Shares. 

2.8 Expiration. Unless earlier terminated in accordance with Section 4.2, this Warrant and the Holder’s rights
hereunder, to the extent not previously exercised, shall expire as of 5:00 P.M., Boston, Massachusetts time, on the Expiration Date. 

3. Adjustments for Stock Dividends, Subdivisions and Combinations. In the event that, at any time and from time to
time after the Initial Exercise Date, the Company shall (a) issue additional shares of Common Stock as a dividend or other distribution on outstanding shares of Common Stock, (b) subdivide its outstanding shares of Common Stock into a
greater number of shares of Common Stock or (c) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then, in each such event, (x) the Exercise Price shall, simultaneously with the happening of
such event, be adjusted by multiplying the then current Exercise Price by a fraction, (i) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such event, and (ii) the denominator of
which shall be the total number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Exercise Price then in effect, and (y) the number of Warrant Shares shall be adjusted by
increasing or decreasing, as the case may be, the number of shares of Common Stock included within the Warrant Shares by the percentage increase or decrease in the total number of shares of Common Stock outstanding immediately after such event over
the total number of shares of Common Stock outstanding immediately prior to such event and the result so obtained shall be the Warrant Shares then in effect. The Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted in the same
manner upon the happening of any successive event or events described in this Section 3. 
 4. Adjustment for
Reorganization; Consolidation or Merger. 
 4.1 Reorganization; Consolidation or Merger. Subject to the terms of
Section 4.2, in case that, at any time or from time to time after the Initial Exercise Date, the Company shall (a) effect a reorganization, (b) consolidate with or merge into any other Person, or (c) transfer all or substantially
all of its properties or assets to any other Person under any plan or arrangement contemplating the dissolution of the Company, then, in each such case, the Holder, on the exercise of this Warrant as provided in Section 2 hereof at any time or
from time to time after the consummation of such reorganization, consolidation or merger or the effective date of such dissolution, as the case may be, shall receive, in lieu of the Warrant Shares issuable on such exercise immediately prior to such
consummation or such effective date, as the case may be, the stock and other securities and property (including cash) to which the Holder would have been entitled upon such consummation or in connection with such dissolution, as the case may be, if
the Holder had so exercised this Warrant immediately prior thereto, all subject to successive adjustments thereafter from time to time pursuant to, and in accordance with, the provisions of Section 3 hereof and this Section 4. 

  
 6 

 4.2 Termination on Change of Control or Initial Public Offering. Unless
exercised in connection therewith (which exercise may be made contemporaneous with and contingent upon the closing of such transaction), this Warrant shall terminate immediately after the consummation of any Change of Control or Initial Public
Offering. 
 4.3 Dissolution. In the event of any dissolution of the Company following the transfer of all or
substantially all of its properties or assets at any time after the Initial Exercise Date, the Company shall retain for a period of at least thirty (30) days after the effective date of such dissolution the stock and other securities and
property (including cash, where applicable) (collectively, the “Property”) receivable by the Holder pursuant to Section 4.1 hereof upon exercise of this Warrant at any time after the effective date of such dissolution. If the
Holder fails to exercise this Warrant within the thirty (30) day period following the effective date of such dissolution, then such Property shall be distributed pro rata to those Persons who were stockholders of record of the Company on
the effective date of such dissolution or as otherwise provided by the Company. 
 4.4 Continuation of Terms. Unless
earlier terminated in accordance with Section 4.2, upon any reorganization, consolidation, merger or transfer (and any dissolution following any such transfer) referred to in this Section 4, this Warrant shall continue in full force and effect
and the terms hereof shall be applicable to the shares of stock and other securities and property receivable upon the exercise of this Warrant after the consummation of such reorganization, consolidation or merger or the effective date of
dissolution following any such transfer, as the case may be, and shall be binding upon the issuer of any such stock or other securities whether or not such Person shall have expressly assumed the terms of this Warrant. 

5. Officer’s Certificate as to Adjustments. In each case of any adjustment or readjustment in the number and
kind of Warrant Shares, or property, issuable hereunder from time to time, or the Exercise Price, the Company, at its expense, will promptly cause an officer of the Company to compute such adjustment or readjustment in accordance with the terms of
this Warrant and prepare a certificate setting forth such adjustment or readjustment and showing the facts upon which such adjustment or readjustment is based. The Company will forthwith mail a copy of each such certificate to the Holder. 

6. Notices of Record Date. In the event of: 

(a) any taking by the Company of a record of the holders of Common Stock for the purpose of determining the holders thereof who are entitled to
receive any shares of Common Stock as a dividend or other distribution or pursuant to a stock split, 
 (b) any reorganization of the
Company, any transfer of all or substantially all the assets of the Company to or consolidation or merger of the Company with or into any other Person, or any other event constituting a Change of Control; 

(c) any voluntary or involuntary dissolution, liquidation or winding-up of the Company; or 

(d) an Initial Public Offering, 

  
 7 

 then and in each such event the Company will mail or cause to be mailed to the Holder a notice specifying
(i) the date on which any such record is to be taken for the purpose of such dividend, distribution or stock split, and stating the amount and character of such dividend, distribution or stock split, (ii) the date on which any such
reorganization, transfer, consolidation, merger, dissolution, liquidation or winding-up is to take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other property deliverable on such reorganization, transfer, consolidation, merger, dissolution, liquidation or winding-up; or (iii) the
date on which such Initial Public Offering is anticipated to close. Such notice shall be mailed at least ten (10) days prior to the date specified in such notice on which any such action is to be taken or event shall occur. 

7. Exchange of Warrant. Subject to the provisions of Section 9 hereof (if and to the extent applicable), this
Warrant shall be exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for new warrants of like tenor, each registered in the name of the Holder or in the name of such other Persons as the Holder may direct
(upon payment by the Holder of any applicable transfer taxes). Each of such new warrants shall be exercisable for such number of Warrant Shares as the Holder shall direct, provided that all of such new warrants shall represent, in the
aggregate, the right to purchase the same number of Warrant Shares which may be purchased by the Holder upon exercise of this Warrant at the time of its surrender. 

8. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, on surrender and cancellation of this Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new warrant of like tenor. 

9. Restrictions on Transfer; Compliance with Securities Act; Mechanics of Transfer. 

9.1 Contractual Transfer Restrictions. Notwithstanding anything expressed or implied in this Warrant to the contrary, in
no event shall the Holder sell, assign, transfer, endorse, pledge, mortgage, hypothecate or otherwise convey or dispose of all or any portion of the Warrant, any Warrant Shares issued from time to time upon exercise of this Warrant, or any interest
in any of the foregoing without the prior written consent of the Board of Directors of the Company and in conformity with the provisions of this Warrant and of any stockholder’s, voting, or other like agreement of the Company to which the
Holder may be required to become a party in accordance with Section 2.1 above. 
 9.2 Securities Laws Restrictions.
Neither this Warrant nor any of the Warrant Shares issued from time to time upon exercise of this Warrant may be offered, sold, assigned, transferred, endorsed, pledged, mortgaged, hypothecated or otherwise conveyed or disposed of by the Holder,
unless (i) any such offer, sale, assignment, transfer, endorsement, pledge, mortgage, hypothecation or other conveyance or disposition shall be effected (A) pursuant to and in conformity with an effective registration statement under the
Securities Act (a “Registered 

  
 8 

 Sale”) or any then available exemption from the registration requirements of the Securities Act,
and (B) pursuant to and in conformity with any applicable state securities or blue sky laws, and (ii) in the case of any offer, sale, assignment, transfer, endorsement, pledge, mortgage, hypothecation or other conveyance or disposition
other than pursuant to a Registered Sale, if requested by the Company, the Holder shall have obtained and delivered to the Company a written legal opinion of counsel (reasonably satisfactory to the Company as to such counsel and as to the substance
of such opinion) to the effect that any such proposed offer, sale, assignment, transfer, endorsement, pledge, mortgage, hypothecation or other conveyance or disposition by the Holder does not violate the registration provisions of the Securities Act
and any applicable state securities or blue sky laws. 
 9.3 Effect of Violation of Transfer Restrictions; Preventive
Measures. Any offer, sale, assignment, transfer, endorsement, pledge, mortgage, hypothecation, or other conveyance or disposition of all or any portion of this Warrant or any Warrant Shares issued from time to time upon exercise of this
Warrant, or of any interest in this Warrant or any of such Warrant Shares, in violation of this Section 9 shall be null and void. The Company may make a notation on its records or give instructions to any of its transfer agents in order to
implement the restrictions on transfer set forth in this Section 9. The Company shall not incur any liability for any delay in recognizing any transfer of this Warrant or of any Warrant Shares issued from time to time upon exercise of this
Warrant if the Company reasonably believes that any such transfer may have been or would be in violation of the provisions of the Securities Act, applicable blue sky laws or this Section 9. 

9.4 Legends. 

(a) Each certificate representing any Warrant Shares issued upon exercise of this Warrant shall bear the following legend: 

“THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS
OF ANY STATE AND MAY NOT BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, ENDORSED, PLEDGED, MORTGAGED, HYPOTHECATED OR OTHERWISE CONVEYED OR DISPOSED OF, UNLESS SUCH SHARES ARE (1) SO REGISTERED OR (2) AN EXEMPTION FROM SUCH REGISTRATION IS
AVAILABLE AND, IF REQUESTED BY THE COMPANY, A WRITTEN LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY IS PROVIDED BY THE TRANSFEROR. IF THE SHARES REPRESENTED BY THIS CERTIFICATE ARE NOT TRANSFERRED PURSUANT TO AN IN CONFORMITY WITH
AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OF 1933 OR IN ACCORDANCE WITH RULE 144 OF THE SECURITIES ACT OF 1933, SUCH SHARES ARE ALSO SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER PURSUANT TO THE COMPANY’S STOCKHOLDERS’
AGREEMENT, AND NO TRANSFER OF SUCH SHARES SHALL BE VALID OR EFFECTIVE IF IT IS NOT EFFECTED IN COMPLIANCE WITH ALL OF SUCH RESTRICTIONS ON TRANSFER. COPIES OF SUCH COMMON STOCK PURCHASE WARRANT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY
THE HOLDER OF RECORD OF SUCH SHARES TO THE SECRETARY OF THORNE HOLDING, CORP.” 

  
 9 

 (b) Each certificate representing any Warrant Shares issued from time to time upon exercise
of this Warrant shall also bear any legend required under any applicable state securities or blue sky laws. 
 9.5
Survival. The obligations of the Holder (and/or of any transferee of the Warrant or any Warrant Shares issued from time to time upon exercise of this Warrant) under this Section 9 shall, with respect to any Warrant Shares issued
from time to time upon exercise of this Warrant, survive the exercise, expiration or other termination, or transfer, of this Warrant indefinitely. 

9.6 Mechanics of Transfer. Any transfer of all or any portion of this Warrant, or of any interest therein, that has been
approved in writing by the Board of Directors of the Company and that is otherwise in compliance with the provisions of this Section 9 shall be effected by surrendering this Warrant to the Company at its principal office, together with
(i) a duly executed form of assignment, in the form attached hereto, (ii) if the Company shall have in place, and the Transferee is not already a party to a stockholder’s, voting, or other like agreement of the Company, an instrument
of accession, executed by the transferee, to such agreement or agreements in substantially the form requested by the Company, and (iii) payment of any applicable transfer taxes, if any. In the event of any such transfer of this Warrant, in
whole, the Company shall issue a new warrant of like tenor to the transferee, representing the right to purchase the same number of Warrant Shares which were purchasable by the Holder upon exercise of this Warrant at the time of its transfer. In the
event of any such transfer of any portion of this Warrant, (i) the Company shall issue a new warrant of like tenor to the transferee, representing the right to purchase the same number of Warrant Shares which were purchasable by the Holder upon
exercise of the transferred portion of this Warrant at the time of such transfer, and (ii) the Company shall issue a new warrant of like tenor to the Holder, representing the right to purchase the number of Warrant Shares purchasable by the
Holder upon exercise of the portion of this Warrant not transferred to such transferee. Until this Warrant or any portion thereof is transferred on the books of the Company, the Company may treat the Holder as the absolute holder of this Warrant and
all right, title and interest therein for all purposes, notwithstanding any notice to the contrary. 
 10. Investment
Representations. 
 (a) This Warrant and the Warrant Shares to be acquired by the Holder as contemplated hereby shall be acquired for
the Holder’s own account, for investment, and not with a view to the resale or distribution thereof or with the present intention of distributing or selling any of such securities. Holder understands that such securities have not been
registered under the Securities Act of 1933, on the ground that the offer and sale of such securities by the Company to the Holder are exempt from the registration requirements of the Securities Act under Section 4(2) thereof as a transaction
not involving any public offering of such securities. The Holder understands that the Company’s reliance on such exemption is predicated in part on the representations of the Holder contained herein. 

  
 10 

 (b) Holder understands that it must bear the economic risk of investment in the Warrant and
the Warrant Shares to be acquired by it hereunder for an indefinite period of time because such securities have not been registered under the Securities Act, and therefore cannot be sold unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. 
 (c) Holder acknowledges and agrees that this Warrant and each certificate
representing Warrant Shares acquired by it hereunder shall bear appropriate restrictive legends referring to the restrictions on transfer applicable to such securities. Holder is an “accredited investor” as defined in Rule 501(a) of
Regulation D promulgated under the Securities Act of 1933. Holder has such knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risk of its investment in the Company. Holder has been furnished
with all information and materials it has requested concerning the Company. 
 (d) Holder acknowledges and agrees that the Company shall make
a notation regarding the restrictions on transfer of the Warrant and the Warrant Shares to be acquired by Holder hereunder in the stock books of the Company, and any purported transfer of such securities shall be reflected in the stock books of the
Company only if and when transferred in compliance with all of the terms and conditions herein. 
 11. General. 

11.1 Statement on Warrant. Irrespective of any adjustments in the Exercise Price or the number or kind of Warrant Shares,
and without limiting or affecting such adjustments, this Warrant may continue to express the same Exercise Price and the same number and kind of Warrant Shares as are stated on the front page hereof. 

11.2 Authorized Shares; Reservation of Shares for Issuance. At all times while this Warrant is outstanding, the Company
shall maintain its corporate authority to issue, and shall have authorized and reserved for issuance upon exercise of this Warrant, such number of shares of Common Stock as shall be sufficient to perform its obligations under this Warrant (after
giving effect to any and all adjustments to the number and kind of Warrant Shares purchasable upon exercise of this Warrant). 
 11.3
No Impairment. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities, sale or other transfer of
any of its assets or properties, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, 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 Holder hereunder against impairment. Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any
shares of Stock receivable upon the exercise of this Warrant above the amount payable therefor on such exercise, and (b) will take all action that may be necessary or appropriate in order that the Company may validly and legally issue fully
paid and nonassessable shares of Stock on the exercise of this Warrant. 

  
 11

breach by it of the provisions of this Warrant and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. In any action or proceeding brought to enforce any provision of this Warrant or
where any provision hereof is validly asserted as a defense, the successful party to such action or proceeding shall be entitled to recover reasonable attorneys’ fees in addition to any other available remedy.

securities laws), (y) payment of the aggregate Exercise Price payable hereunder in respect of the number of Warrant Shares being purchased upon exercise of this Warrant, and (z) if applicable, the payment of any transfer taxes required to be

provided in Section 2.1 above, of all or any portion of the aggregate Exercise Price payable in respect of the number of Warrant Shares for which this Warrant is being exercised, the Holder may pay all or such portion of such aggregate Exercise
Price by electing not to receive all of such Warrant Shares otherwise issuable upon such exercise but only to receive that number of such Warrant Shares as shall be determined in accordance with the following formula: 

  
 3 

 X = Y(A-B) 

      A 
  

			
	 Where: X =
	  	the number of Warrant Shares to be issued to the Holder pursuant to this Section 2.1(b)
		
	          Y =
	  	the number of Warrant Shares for which this Warrant is being exercised as of the applicable Exercise Date
		
	          A =
	  	the Fair Market Value as of the applicable Exercise Date of a share of Common Stock constituting such Warrant Shares
		
	          B =
	  	the Exercise Price in effect as of the applicable Exercise Date of Common Stock constituting such Warrant Shares

forth in, this Section 2.1(b) by surrendering this Warrant to the Company at its principal office, together with (a) a properly completed and duly executed net issue exercise election, in the form attached hereto, which net issue exercise
election shall specify the number of Warrant Shares for which this Warrant is then being exercised (which shall include the number of Warrant Shares to be surrendered as payment therefore) and the Person to whom the Warrant Shares shall be issued,
who may be an Affiliate of the Holder, (b) if requested by the Company, a duly executed instrument or certificate, in form and substance satisfactory to the Company, pursuant to which the Holder or such Affiliate makes such representations and
warranties to the Company, and provides or confirms such information, in each case, concerning the Holder or such Affiliate, as the Company may reasonably request (including, without limitation, such representations and warranties and such
information as may be required in order to confirm compliance with applicable securities laws), (c) if not already a party thereto, an instrument of accession to the Stockholder Agreement and the Registration Rights Agreement, in each case, dated as
of the Initial Exercise Date, in substantially the form requested by the Company, and (d) if applicable, the payment of any transfer taxes required to be paid by the Holder pursuant to Section 2.7 hereof. Payment of such transfer taxes
shall be made in cash, by money order, certified or bank cashier’s check or wire transfer (in each case in lawful currency of the United States of America). Any such exercise pursuant to this Section 2.1(b) may be made contemporaneous
with, and contingent upon, the applicable Change of Control or Initial Public Offering. For the avoidance of doubt, unless indicated otherwise, references to “exercise” herein shall refer to an exercise of this Warrant under
Section 2.1(a) or a net issue exercise under Section 2.1(b). 
 2.2 Effectiveness of Exercise; Ownership.
Each exercise of this Warrant by the Holder shall be deemed to have been effected immediately prior to the close of business on the date upon which all of the requirements of Section 2.1(a) or 2.1(b) hereof, as applicable, with respect to such
exercise shall have been complied with in full (each such date, an “Exercise Date”). On the applicable Exercise Date with respect to any exercise of this Warrant by the 

  
 4 

 
Holder, the Company shall be deemed to have issued to the Holder, and the Holder shall be deemed to have become the holder of record and legal owner of, the number of Warrant Shares being
purchased upon such exercise of this Warrant, notwithstanding that the stock transfer books of the Company may then be closed or that certificates representing such number of Warrant Shares being purchased may not then be actually delivered to the
Holder. 
 2.3 Delivery of Stock Certificates on Exercise. As soon as practicable after the exercise of this Warrant,
and in any event within thirty (30) days thereafter, the Company, at its expense, will cause to be issued in the name of and delivered to the Holder, or as the Holder may direct (upon payment by the Holder of any applicable transfer taxes as
required by Section 2.7 hereof and subject to, in all cases, the provisions of Section 9 hereof), a certificate or certificates for the number of Warrant Shares purchased by the Holder on such exercise, plus, in lieu of any fractional
share to which the Holder would otherwise be entitled, cash equal to such fraction multiplied by the Fair Market Value. 
 2.4
Shares To Be Fully Paid and Nonassessable. All Warrant Shares issued upon the exercise of this Warrant shall be validly issued, fully paid and nonassessable, free of all liens, taxes, charges and other encumbrances or restrictions on
sale (other than those set forth herein, including restrictions under the Stockholder Agreement and the Registration Rights Agreement) and free and clear of all preemptive rights and, assuming no change in the federal and state securities laws and
assuming the Holder exercising the Warrants is an accredited investor, will be issued in compliance with all applicable federal and state securities laws. 

2.5 Fractional Shares. No fractional shares of Stock or scrip representing fractional shares of Stock shall be issued
upon the exercise of this Warrant. With respect to any fraction of a share of Stock called for upon any exercise hereof, the Company shall make a cash payment to the Holder as set forth in Section 2.3 hereof. 

2.6 Issuance of New Warrants; Company Acknowledgment. Upon any partial exercise of this Warrant, the Company, at its
expense, will forthwith issue and deliver to the Holder a new warrant or warrants of like tenor, registered in the name of the Holder, and exercisable, in the aggregate, for the balance of the Warrant Shares. Moreover, the Company shall, at the time
of any exercise of this Warrant, upon the request of the Holder, acknowledge in writing its continuing obligation to afford to the Holder any rights to which the Holder shall continue to be entitled after such exercise in accordance with the
provisions of this Warrant; provided, however, that if the Holder shall fail to make any such request, such failure shall not affect the continuing obligation of the Company to afford to the Holder any such rights. 

2.7 Payment of Taxes and Expenses. The Holder shall be required to pay any tax which may be payable in respect of any
transfer involved in the issuance of, and the preparation and delivery of certificates (if applicable) representing, (i) any Warrant Shares purchased upon exercise of this Warrant and issued in a name other than that or the Holders and/or
(ii) new or replacement warrants in a name other than that of the Holder, and, until the payment of such tax, the Company shall not be required to issue or cause to be issued any such purchased Warrant Shares or any such new or replacement
warrants, and the Company shall also not be required to prepare and deliver, or to cause to be prepared and delivered, certificates representing any such purchased Warrant Shares. 

  
 5 

 2.8 Expiration. Unless earlier terminated in accordance with
Section 4.2, this Warrant and the Holder’s rights hereunder, to the extent not previously exercised, shall expire as of 5:00 P.M., Boston, Massachusetts time, on the Expiration Date. 

3. Adjustments for Stock Dividends, Subdivisions and Combinations. In the event that, at any time and from time to
time after the Initial Exercise Date, the Company shall (a) issue additional shares of Common Stock as a dividend or other distribution on outstanding shares of Common Stock, (b) subdivide its outstanding shares of Common Stock into a
greater number of shares of Common Stock or (c) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, then, in each such event, (x) the Exercise Price shall, simultaneously with the happening of
such event, be adjusted by multiplying the then current Exercise Price by a fraction, (i) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such event, and (ii) the denominator of
which shall be the total number of shares of Common Stock outstanding immediately after such event, and the product so obtained shall thereafter be the Exercise Price then in effect, and (y) the number of Warrant Shares shall be adjusted by
increasing or decreasing, as the case may be, the number of shares of Common Stock included within the Warrant Shares by the percentage increase or decrease in the total number of shares of Common Stock outstanding immediately after such event over
the total number of shares of Common Stock outstanding immediately prior to such event and the result so obtained shall be the Warrant Shares then in effect. The Exercise Price and the Warrant Shares, as so adjusted, shall be readjusted in the same
manner upon the happening of any successive event or events described in this Section 3. Without limiting the foregoing, if at any time after the Initial Exercise Date, the DNP Warrant is amended, restated, supplemented or otherwise modified
(including by issuance of additional warrants or stock purchase rights pursuant to a separate instrument or instruments, other than additional warrants or stock purchase rights under a separate instrument or instruments acquired by DNP for new and
additional fair market value consideration) to (A) increase the number of shares of Common Stock (or shares of Stock or other securities of the Company) purchasable by DNP or its successors or assigns, (B) reduce the exercise price for
warrant shares purchasable by DNP or its successors or assigns, (C) extend the exercise period thereof, or (D) any other change with similar effect, and corresponding and appropriate adjustments are not made to this Warrant pursuant to
Section 3 or Section 4, then corresponding and proportionate adjustments shall automatically be made to the terms and conditions of this Warrant, including the number of Warrant Shares and the Exercise Price hereunder, if applicable, to
reflect the DNP Warrant (including any additional warrants or stock purchase rights) as so modified. 
 4. Adjustment for
Reorganization; Consolidation or Merger.  
 4.1 Reorganization; Consolidation or Merger. Subject to the
terms of Sections 4.2 and 4.3 hereof, in case that, at any time or from time to time after the Initial Exercise Date, the Company shall (a) effect a reorganization, (b) consolidate with or merge into any other Person, or (c) transfer
all or substantially all of its properties or assets to any other Person under any plan or arrangement contemplating the dissolution of the Company, then, in each such case, the Holder, on the exercise of this Warrant as provided in Section 2
hereof at any time or from time to time after the consummation of such reorganization, consolidation or merger or the effective date of such dissolution, as the case may be, shall receive, in lieu of the Warrant Shares issuable on such exercise
immediately prior to such consummation or such effective date, as the case may 

  
 6 

 
be, the stock and other securities and property (including cash) to which the Holder would have been entitled upon such consummation or in connection with such dissolution, as the case may be, if
the Holder had so exercised this Warrant immediately prior thereto, all subject to successive adjustments thereafter from time to time pursuant to, and in accordance with, the provisions of Section 3 hereof and this Section 4. 

4.2 Termination on Change of Control or Initial Public Offering. Subject to Section 4.3 and the Company’s
compliance with Section 6 hereof, unless exercised in connection therewith (which exercise may be made contemporaneous with and contingent upon the closing of such transaction), this Warrant shall terminate immediately after the consummation of
any Change of Control or Initial Public Offering. 
 4.3 Dissolution. In the event of any dissolution of the Company
following the transfer of all or substantially all of its properties or assets at any time after the Initial Exercise Date, the Company shall retain for a period of at least thirty (30) days after the effective date of such dissolution the
stock and other securities and property (including cash, where applicable) (collectively, the “Property”) receivable by the Holder pursuant to Section 4.1 hereof upon exercise of this Warrant at any time after the effective
date of such dissolution. If the Holder fails to exercise this Warrant within the thirty (30) day period following the effective date of such dissolution, then such Property shall be distributed pro rata to those Persons who were
stockholders of record of the Company on the effective date of such dissolution or as otherwise provided by the Company. 
 4.4
Continuation of Terms. Unless earlier terminated in accordance with Section 4.2, upon any reorganization, consolidation, merger or transfer (and any dissolution following any such transfer) referred to in this Section 4, this
Warrant shall continue in full force and effect and the terms hereof shall be applicable to the shares of stock and other securities and property receivable upon the exercise of this Warrant after the consummation of such reorganization,
consolidation or merger or the effective date of dissolution following any such transfer, as the case may be, and shall be binding upon the issuer of any such stock or other securities whether or not such Person shall have expressly assumed the
terms of this Warrant. 
 5. Officer’s Certificate as to Adjustments. In each case of any adjustment or
readjustment in the number and kind of Warrant Shares, or property, issuable hereunder from time to time, or the Exercise Price, the Company, at its expense, will promptly cause an officer of the Company to compute such adjustment or readjustment in
accordance with the terms of this Warrant and prepare a certificate setting forth such adjustment or readjustment and showing the facts upon which such adjustment or readjustment is based. The Company will forthwith mail a copy of each such
certificate to the Holder. 
 6. Notices of Record Date. In the event of: 

(a) any taking by the Company of a record of the holders of Common Stock for the purpose of determining the holders thereof who are entitled
to receive any shares of Common Stock as a dividend or other distribution or pursuant to a stock split,

 (b) any reorganization of the Company, any transfer of all or substantially all the assets
of the Company to or consolidation or merger of the Company with or into any other Person, or any other event constituting a Change of Control; 

(c) any voluntary or involuntary dissolution, liquidation or winding-up of the Company; or 

(d) an Initial Public Offering, 
 then and in
each such event the Company will mail or cause to be mailed to the Holder a notice specifying (i) the date on which any such record is to be taken for the purpose of such dividend, distribution or stock split, and stating the amount and
character of such dividend, distribution or stock split, (ii) the date on which any such reorganization, transfer, consolidation, merger, Change of Control, dissolution, liquidation or winding-up is to
take place, and the time, if any is to be fixed, as of which the holders of record of Common Stock shall be entitled to exchange their shares of Common Stock for securities or other property deliverable on such reorganization, transfer,
consolidation, merger, dissolution, liquidation or winding-up; or (iii) the date on which such Initial Public Offering is anticipated to close. Such notice shall be delivered at least ten (10) days
prior to the date specified in such notice on which any such action is to be taken or event shall occur. Notwithstanding anything contained in this Section 6, in the event of an exercise of the DNP Warrant, the Company shall not be required to
provide notice to the Holder prior to such exercise, but shall instead mail notice to the Holder promptly following such exercise (but in no event later than five (5) business days following such exercise); and any corresponding “Change of
Control” to occur hereunder as a result of the exercise of the DNP Warrant (including any acceleration and/or termination of this Warrant) in connection with such exercise of the DNP Warrant shall be deemed to occur ten (10) days following
the delivery of such notice, or on such other date (not less than ten (10) days after delivery of such notice) as is specified in such notice, or as otherwise mutually agreed between the Company and the Holder. 

7. Exchange of Warrant. Subject to the provisions of Section 9 hereof (if and to the extent applicable), this
Warrant shall be exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for new warrants of like tenor, each registered in the name of the Holder or in the name of such other Persons as the Holder may direct
(upon payment by the Holder of any applicable transfer taxes). Each of such new warrants shall be exercisable for such number of Warrant Shares as the Holder shall direct, provided that all of such new warrants shall represent, in the
aggregate, the right to purchase the same number of Warrant Shares which may be purchased by the Holder upon exercise of this Warrant at the time of its surrender. 

8. Replacement of Warrant. On receipt of evidence reasonably satisfactory to the Company of the loss, theft,
destruction or mutilation of this Warrant and, in the case of any such loss, theft or destruction of this Warrant, on delivery of an indemnity agreement or security reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, on surrender and cancellation of this Warrant, the Company at its expense will execute and deliver, in lieu thereof, a new warrant of like tenor. In the event of any amendment, modification or adjustment to this Warrant in
accordance with the last sentence of Section 3 or the last sentence of Section 11.6, the Company at its expense will execute and deliver, in lieu hereof, a new warrant reflecting such changes and a certificate setting forth such
adjustments and showing the facts upon which such adjustments are based and send each to the Holder in accordance with the notice provisions hereof.

 9. Restrictions on Transfer; Compliance with Securities Act; Mechanics of
Transfer.  
 9.1 Contractual Transfer Restrictions. Notwithstanding anything expressed or implied in
this Warrant to the contrary, in no event shall the Holder sell, assign, transfer, endorse, pledge, mortgage, hypothecate or otherwise convey or dispose of all or any portion of the Warrant, any Warrant Shares issued from time to time upon exercise
of this Warrant, or any interest in any of the foregoing to any Person other than an Affiliate (as defined in the Stockholders Agreement) without the prior written consent of the Board of Directors of the Company and in conformity with the
provisions of this Warrant and the Stockholder Agreement and Registration Rights Agreement to which the Holder may be required to become a party in accordance with Section 2.1 above. If not already a party thereto, any Affiliate of the Holder
shall, upon exercise of this Warrant, execute and deliver to the Company an instrument of accession to the Stockholder Agreement and the Registration Rights Agreement, in substantially the form requested by the Company, in accordance with
Section 2.1. 
 9.2 Securities Laws Restrictions. Neither this Warrant nor any of the Warrant Shares issued from
time to time upon exercise of this Warrant may be offered, sold, assigned, transferred, endorsed, pledged, mortgaged, hypothecated or otherwise conveyed or disposed of by the Holder, unless (i) any such offer, sale, assignment, transfer,
endorsement, pledge, mortgage, hypothecation or other conveyance or disposition shall be effected (A) pursuant to and in conformity with an effective registration statement under the Securities Act (a “Registered Sale”)
or any then available exemption from the registration requirements of the Securities Act, and (B) pursuant to and in conformity with any applicable state securities or blue sky laws, and (ii) in the case of any offer, sale, assignment,
transfer, endorsement, pledge, mortgage, hypothecation or other conveyance or disposition other than pursuant to a Registered Sale, if reasonably requested by the Company, the Holder shall have obtained and delivered to the Company a written legal
opinion of counsel (reasonably satisfactory to the Company as to such counsel and as to the substance of such opinion) to the effect that any such proposed offer, sale, assignment, transfer, endorsement, pledge, mortgage, hypothecation or other
conveyance or disposition by the Holder does not violate the registration provisions of the Securities Act and any applicable state securities or blue sky laws. 

9.3 Effect of Violation of Transfer Restrictions; Preventive Measures. Any offer, sale, assignment, transfer, endorsement,
pledge, mortgage, hypothecation, or other conveyance or disposition of all or any portion of this Warrant or any Warrant Shares issued from time to time upon exercise of this Warrant, or of any interest in this Warrant or any of such Warrant Shares,
in violation of this Section 9 shall be null and void. The Company may make a notation on its records or give instructions to any of its transfer agents in order to implement the restrictions on transfer set forth in this Section 9. The
Company shall not incur any liability for any delay in recognizing any transfer of this Warrant or of any Warrant Shares issued from time to time upon exercise of this Warrant if the Company reasonably believes that any such transfer may have been
or would be in violation of the provisions of the Securities Act, applicable blue sky laws or this Section 9. 

  
 9 

 9.4 Legends. 

(a) Each certificate representing any Warrant Shares issued upon exercise of this Warrant shall bear the legends required pursuant to the
Stockholders Agreement and Registration Rights Agreement. 
 (b) Each certificate representing any Warrant Shares issued from time to time
upon exercise of this Warrant shall also bear any legend required under any applicable state securities or blue sky laws. 
 9.5
Survival. The obligations of the Holder (and/or of any transferee of the Warrant or any Warrant Shares issued from time to time upon exercise of this Warrant) under this Section 9 shall, with respect to any Warrant Shares issued
from time to time upon exercise of this Warrant, survive the exercise, expiration or other termination, or transfer, of this Warrant indefinitely. 

9.6 Mechanics of Transfer. Any transfer of all or any portion of this Warrant, or of any interest therein, to an
Affiliate of the Holder or that has been approved in writing by the Board of Directors of the Company and that is otherwise in compliance with the provisions of this Section 9 shall be effected by surrendering this Warrant to the Company at its
principal office, together with (i) a duly executed form of assignment, in the form attached hereto and (ii) payment of any applicable transfer taxes, if any. In the event of any such transfer of this Warrant, in whole, the Company shall
issue a new warrant of like tenor to the transferee, representing the right to purchase the same number of Warrant Shares which were purchasable by the Holder upon exercise of this Warrant at the time of its transfer. In the event of any such
transfer of any portion of this Warrant, (i) the Company shall issue a new warrant of like tenor to the transferee, representing the right to purchase the same number of Warrant Shares which were purchasable by the Holder upon exercise of the
transferred portion of this Warrant at the time of such transfer, and (ii) the Company shall issue a new warrant of like tenor to the Holder, representing the right to purchase the number of Warrant Shares purchasable by the Holder upon
exercise of the portion of this Warrant not transferred to such transferee. Until this Warrant or any portion thereof is transferred in accordance with this Warrant, the Company may treat the Holder as the absolute holder of this Warrant and all
right, title and interest therein for all purposes, notwithstanding any notice to the contrary. 
 10. Investment
Representations.  
 (a) This Warrant and the Warrant Shares to be acquired by the Holder as contemplated hereby shall be
acquired for the Holder’s own account, for investment, and not with a view to the resale or distribution thereof or with the present intention of distributing or selling any of such securities. Holder understands that such securities have not
been registered under the Securities Act of 1933, on the ground that the offer and sale of such securities by the Company to the Holder are exempt from the registration requirements of the Securities Act under Section 4(2) thereof as a
transaction not involving any public offering of such securities. The Holder understands that the Company’s reliance on such exemption is predicated in part on the representations of the Holder contained herein. 

  
 10 

 (b) Holder understands that it may bear the economic risk of investment in the Warrant and
the Warrant Shares to be acquired by it hereunder for an indefinite period of time because such securities have not been registered under the Securities Act, and therefore may not be sold unless they are subsequently registered under the Securities
Act or an exemption from such registration is available. 
 (c) Holder acknowledges and agrees that this Warrant and each certificate
representing Warrant Shares acquired by it hereunder shall bear appropriate restrictive legends referring to the restrictions on transfer applicable to such securities. Holder is an “accredited investor” as defined in Rule 501(a) of
Regulation D promulgated under the Securities Act of 1933. Holder has such knowledge and experience in financial and business matters so as to be capable of evaluating the merits and risk of its investment in the Company. Holder has been furnished
with all information and materials it has requested concerning the Company. 
 (d) Holder acknowledges and agrees that the Company shall
make a notation regarding the restrictions on transfer of the Warrant and the Warrant Shares to be acquired by Holder hereunder in the stock books of the Company, and any purported transfer of such securities shall be reflected in the stock books of
the Company only if and when transferred in compliance with all of the terms and conditions herein. 
 11. General. 

11.1 Statement on Warrant. Irrespective of any adjustments in the Exercise Price or the number or kind of Warrant Shares,
and without limiting or affecting such adjustments, this Warrant may continue to express the same Exercise Price and the same number and kind of Warrant Shares as are stated on the front page hereof, subject to Section 3. 

11.2 Authorized Shares; Reservation of Shares for Issuance. At all times while this Warrant is outstanding, the Company
shall maintain its corporate authority to issue, and shall have authorized and reserved for issuance upon exercise of this Warrant, such number of shares of Common Stock as shall be sufficient to perform its obligations under this Warrant (after
giving effect to any and all adjustments to the number and kind of Warrant Shares purchasable upon exercise of this Warrant). 
 11.3
No Impairment. The Company will not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issuance or sale of securities, sale or other transfer of
any of its assets or properties, or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, 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 Holder hereunder against impairment. Without limiting the generality of the foregoing, the Company (a) will not increase the par value of any
shares of Stock receivable upon the exercise of this Warrant above the amount payable therefor on such exercise, and (b) will take all action that may be necessary or appropriate in order that the Company may validly and legally issue fully paid and
nonassessable shares of Stock on the exercise of this Warrant. 

  
 11 

 11.4 No Rights as Stockholder. The Holder shall not be entitled to vote
or to receive dividends or to be deemed the holder of Stock that may at any time be issuable upon exercise of this Warrant for any purpose whatsoever, nor shall anything contained herein be construed to confer upon the Holder any of the rights of a
stockholder of the Company or any right to vote for the election of directors or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance or
reclassification of stock, change of par value or change of stock to no par value, consolidation, merger or conveyance or otherwise), or to receive notice of meetings (except to the extent otherwise provided in this Warrant), or to receive dividends
or subscription rights, until the Holder shall have exercised the Warrant in accordance with the provisions hereof. 
 11.5
Notices. (i) Any notices, reports or other correspondence (hereinafter collectively referred to as “correspondence”) required or permitted to be given hereunder shall be sent by courier (overnight or same day)
or telecopy or delivered by hand to the party to whom such correspondence is required or permitted to be given hereunder. The date of giving any notice shall be the date of its actual receipt.

11.6 Amendment and Waiver. No failure or delay of the Holder in exercising any power or right hereunder shall operate as
a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right
or power. The rights and remedies of the Holder arc cumulative and not exclusive of any rights or remedies which it would otherwise have. The provisions of this Warrant may be amended, modified or waived with (and only with) the written consent of
the Company and the Holder. Notwithstanding the foregoing, if any amendment is made to the terms or conditions of the DNP Warrant that results in a material benefit to DNP or its successors or assigns (including by granting to any such Person any
material right or privilege, or by removing any material restriction or condition), the corresponding terms and conditions of this Warrant shall automatically be amended, in like manner, without the requirement of any action on the part of the
Holder or the Company (except as set forth in Section 8). 
 11.7 Governing Law. This Warrant shall be construed
in accordance with and governed by the laws of the State of New York. 
 11.8 Covenants To Bind Successor and Assigns.
All covenants, stipulations, promises and agreements in this Warrant contained by or on behalf of the Company shall bind its successors and assigns, whether so expressed or not. 

  
 13 

 11.9 Severability. In case anyone or more of the provisions contained
in this Warrant shall be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby. The parties shall endeavor in
good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions. 

11.10 Construction. The definitions of this Warrant shall apply equally to both the singular and the plural forms of the
terms defined. Wherever the context may require, any pronoun shall include the corresponding masculine, feminine and neuter forms. The section and paragraph headings used herein are for convenience of reference only, are not part of this Warrant and
are not to affect the construction of or be taken into consideration in interpreting this Warrant. 
 11.11 Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate
compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. In any action or proceeding
brought to enforce any provision of this Warrant or where any provision hereof is validly asserted as a defense, the successful party to such action or proceeding shall be entitled to recover reasonable attorneys’ fees in addition to any other
available remedy.
