THIS IS TO CERTIFY THAT, Kirin Holdings Company, Limited (the “Initial Warrant Holder”) and its successors and permitted
assigns are entitled to purchase from Thorne Holding Corp., a Delaware corporation (the “Company”), at any time or from time to time after 9:00 A.M., New York City time, on October 11, 2018 (such day, the “Initial
Exercise Date”), and prior to 5:00 P.M., New York City time, on the ten (10) year anniversary of the Initial Exercise Date (the “Expiration Date”), any or all of one hundred twenty-seven (127) shares (the
“Initial Warrant Shares”) of Common Stock (as defined below) of the Company at a purchase price per share equal to $2,280.03 per share (the “Initial Exercise Price”). The number and character of the Initial
Warrant Shares and the Initial Exercise Price are subject to adjustment as provided herein.

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) or through a “cashless exercise” in the manner provided in Section 2.01(b).

X = Y(A-B) 

        A 
  

			
	 Where: X =
	  	the number of Warrant Shares to be issued to the Holder pursuant to this Section 2.01(b)
		
	          Y=
	  	the number of Warrant Shares for which this Warrant is being exercised as of the applicable Exercise Date

	  	the Fair Market Value as of the applicable Exercise Date of a share of Common Stock constituting such Warrant Shares
		
	          B=
	  	the Exercise Price for such Warrant Shares in effect as of the applicable Exercise Date

  
 4 

 The Holder may elect to make payment of all or any portion of such aggregate Exercise Price pursuant to, and

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 or its applicable Affiliate, and the Holder or
its applicable Affiliate 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 or its applicable Affiliate. 

Section 2.03. 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 its applicable Affiliate, or as the Holder or its applicable Affiliate may direct
(upon payment by the Holder of any applicable transfer taxes as required by Section 2.07 and subject to, in all cases, the provisions of Article IX), a certificate or certificates for the number of Warrant Shares to be issued to the Holder or
its applicable Affiliate 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. 

Section 2.04. 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 will be issued in compliance with all applicable federal and state securities laws. 

Section 2.05. Fractional Shares. No fractional Warrant Shares or scrip representing fractional Warrant Shares
shall be issued upon the exercise of this Warrant. With respect to any fraction of a Warrant Share called for upon any exercise hereof, the Company shall make a cash payment to the Holder as set forth in Section 2.03.

Acknowledgment. Upon any partial exercise or transfer 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. 
 Section 2.07. 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 of the Holders and/or (ii) new or replacement warrants in a name other than that of the Holder. 

Section 2.08. Expiration. This Warrant and the Holder’s rights hereunder, to the extent not previously
exercised, shall expire as of 5:00 P.M., New York City time, on the Expiration Date. 
 ARTICLE III 

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 (or other applicable Warrant Shares) as a dividend or other distribution on outstanding shares of
Common Stock (or other applicable Warrant Shares), (b) subdivide its outstanding shares of Common Stock (or other applicable Warrant Shares) into a greater number of shares of Common Stock (or other applicable Warrant Shares) or (c) combine its
outstanding shares of Common Stock (or other applicable Warrant Shares) into a smaller number of shares of Common Stock (or other applicable Warrant Shares), 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 (or other applicable Warrant Shares) outstanding immediately prior
to such event, and (ii) the denominator of which shall be the total number of shares of Common Stock (or other applicable Warrant Shares) 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 (or other applicable Warrant Shares) included within the Warrant Shares by the
percentage increase or decrease in the total number of shares of Common Stock (or other applicable Warrant Shares) outstanding immediately after such event over the total number of shares of Common Stock (or other applicable Warrant Shares)
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

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 and received Warrant Shares immediately prior thereto, all subject to successive adjustments thereafter from time to time pursuant to, and in accordance with, the provisions of Article III and this
Article IV.

dissolution the stock and other securities and property (including cash, where applicable) (collectively, the “Property”) receivable by the Holder pursuant to Section 4.01 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 sixty (60) day period following the effective date of such dissolution, then such Property shall be distributed pro rata to those Persons who were

securities whether or not such Person shall have expressly assumed the terms of this Warrant.

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.

 ARTICLE VI 

NOTICES OF RECORD DATE 
 In
the event of: 
 (a) any taking by the Company of a record of the holders of Warrant Shares for the purpose of determining the holders

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

 ARTICLE X 

INVESTMENT REPRESENTATIONS 

Section 10.01. Investment Representations. 

(a) This Warrant and the Warrant Shares to be acquired by the Holder as contemplated hereby are being 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. The 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. 

(b) The 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) The 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. 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.

 Section 11.02. Reserved. 

Section 11.03. 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 Warrant Shares 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).

 Section 11.04. No Impairment. The Company will not, by amendment
of its Certificate of Incorporation or through any reorganization, transfer (including by exclusive license) 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 Warrant Shares 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 Warrant Shares
on the exercise of this Warrant. 
 Section 11.05. No Rights as Stockholder. The Holder shall not be
entitled to vote or to receive dividends or to be deemed the holder of Warrant Shares 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. 

Section 11.06. Notice. All notices and other communications hereunder shall be in writing and shall be deemed

surrender of this Warrant to the Company at its principal office, together with (x) a properly completed and duly executed subscription form, in the form attached hereto as Exhibit A, which subscription form shall specify the number of Warrant
Shares for which this Warrant is then being exercised and the Person to whom the Warrant Shares shall be issued, who may be the Holder or an Affiliate of the Holder, (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 paid by the Holder pursuant to Section 2.07. Payment of such aggregate Exercise Price shall

	 	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 for such Warrant Shares in effect as of the applicable Exercise Date

 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 2.01(b) by surrendering this Warrant to the Company at its principal office, together with (x) a properly completed and duly executed net

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 or its applicable Affiliate, and the Holder or
its applicable Affiliate 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 or its applicable Affiliate. 

Section 2.03. 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 its applicable Affiliate, or as the Holder or its applicable Affiliate may direct
(upon payment by the Holder of any applicable transfer taxes as required by Section 2.07 and subject to, in all cases, the provisions of Article IX), a certificate or certificates for the number of Warrant Shares to be issued to the Holder or
its applicable Affiliate 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. 

Section 2.04. 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 will be issued in compliance with all applicable federal and state securities laws. 

Section 2.05. Fractional Shares. No fractional Warrant Shares or scrip representing fractional Warrant Shares
shall be issued upon the exercise of this Warrant. With respect to any fraction of a Warrant Share called for upon any exercise hereof, the Company shall make a cash payment to the Holder as set forth in Section 2.03.

Acknowledgment. Upon any partial exercise or transfer 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. 
 Section 2.07. 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 of the Holders and/or (ii) new or replacement warrants in a name other than that of the Holder.

exercised, shall expire as of 5:00 P.M., New York City time, on the Expiration Date.

Common Stock (or other applicable Warrant Shares), (b) subdivide its outstanding shares of Common Stock (or other applicable Warrant Shares) into a greater number of shares of Common Stock (or other applicable Warrant Shares) or (c) combine its
outstanding shares of Common Stock (or other applicable Warrant Shares) into a smaller number of shares of Common Stock (or other applicable Warrant Shares), 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 (or other applicable Warrant Shares) outstanding immediately prior
to such event, and (ii) the denominator of which shall be the total number of shares of Common Stock (or other applicable Warrant Shares) 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 (or other applicable Warrant Shares) included within the Warrant Shares by the
percentage increase or decrease in the total number of shares of Common Stock (or other applicable Warrant Shares) outstanding immediately after such event over the total number of shares of Common Stock (or other applicable Warrant Shares)
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

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 and received Warrant Shares immediately prior thereto, all subject to successive adjustments thereafter from time to time pursuant to, and in accordance with, the provisions of Article III and this
Article IV.

dissolution the stock and other securities and property (including cash, where applicable) (collectively, the “Property”) receivable by the Holder pursuant to Section 4.01 upon exercise of this Warrant at any time after the

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

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.

INVESTMENT REPRESENTATIONS 

Section 10.01. Investment Representations. 

(a) This Warrant and the Warrant Shares to be acquired by the Holder as contemplated hereby are being 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. The 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. 

(b) The 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) The 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. 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.

 Section 11.02. Reserved. 

Section 11.03. 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 Warrant Shares as shall be sufficient to perform its obligations under this

 license) 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 Warrant Shares 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 Warrant Shares on the exercise of this Warrant. 
 Section 11.05. No Rights as
Stockholder. The Holder shall not be entitled to vote or to receive dividends or to be deemed the holder of Warrant Shares 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. 

Section 11.06. Notice. All notices and other communications hereunder shall be in writing and shall be deemed

 Section 11.07. 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 are 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.

laws of the State of New York without giving effect to any choice or conflict of law provision or rule (whether of the State of New York or any other jurisdiction).

in this Warrant contained by or on behalf of the Company shall bind its successors and assigns, whether so expressed or not. 

Section 11.10. 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. 

Section 11.11. 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. 

Section 11.12. 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 the terms of 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 or other equitable relief 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 its reasonable attorneys’ fees and costs in addition to any other available remedy.
