Dear Sirs 
 Re: Guarantee—fee letter 

This letter (the “Fee Letter”) is entered into in connection with the Guarantee Letter
(hosho-sho) (the “Guarantee”) to be submitted by Kirin Holdings Company, Limited (“Kirin”) in favor of Sumitomo Mitsui Banking Corporation New York Branch (the
“Beneficiary”) for the benefit of THORNE HOLDING CORP. (the “Company”), pursuant to which Kirin guarantees certain obligations of the Company under the Uncommitted and Revolving Credit Line Agreement, to be entered
into by and between the Beneficiary and the Company, substantially in the form attached hereto as Exhibit A, subject to the limitations and other terms set forth in the Guarantee. 

In connection with, and as consideration for Kirin to enter into, the Guarantee, the Company and Kirin hereby agree as follows: 

 

	 	a)	 The Company agrees to pay Kirin for its own account, an annual fee at the rate per annum of 2.00% of
$10,000,000 (the “Fee”), until the Guarantee is terminated. The Company shall pay the Fee and any other amounts accrued or otherwise payable pursuant to this Fee Letter (i) on an annual basis on each anniversary of the Effective Date,
as defined below; and (ii) upon the occurrence of any change of control in respect of the Company; provided that, upon the termination of the Guarantee, the Fee payable with respect to a partial year in which the Guarantee was terminated shall
be equal to (x) the Fee multiplied by (y)(i) the number of days elapsed in such year (beginning on the relevant anniversary of the Effective Date) up to such termination divided by (ii) 365. Payment shall be made by wire transfer of immediately
available funds to a bank account designated by Kirin. 


  

	 	b)	 The Company agrees to reimburse Kirin for any reasonably incurred fees or expenses related to or in connection
with any disputes arising between Kirin and the Beneficiary out of or in connection with the Guarantee including, but not limited to, attorney fees and costs for litigation. 



 

	 	c)	 In the event that Kirin is required to pay any amounts under the Guarantee, such amounts shall promptly be
reimbursed by the Company to Kirin in cash. In case the Company is not able to wholly or partially reimburse such amounts to Kirin, the parties may agree to deem the unreimbursed amount of Kirin’s payment under the Guarantee to be made for the
benefit of the Company in consideration for debt or equity securities of the Company on terms reasonably satisfactory to Kirin and the Company. 















	 	d)	 The Company agrees to provide Kirin with the following documents; 



i. Monthly P&L, Balance Sheet, and Cashflow Statement within 21 days of the end of each month 

ii. Next 12 months cashflow estimate, which will be updated every quarter, by the end of last day of the month after the end of each quarter
(i.e. 2020/Q2-2021/Q1 estimate to come by April 30th, 2020) 
 iii. Monthly borrowing detail (amount,
interest rate, term) within 10 days of the end of each month 
  

	 	e)	 The Company agrees to fully pay back to Kirin immediately after the Uncommitted and Revolving Credit Line is
executed, in accordance with the letter dated on July 26, 2019 between the Company and Kirin, all and any indebtedness and accrued interest thereof arising out of or in connection with (i) Promissory Note Purchase and Sale Agreement dated
July 26, 2019 and (ii) Unsecured Subordinated Promissory Note dated July 26, 2019 between the Company and Kirin. 


 The
Company agrees that all of the fees and expenses set forth in this Fee Letter shall be fully earned upon becoming due and payable in accordance with the terms hereof. 

This Fee Letter, together with the Guarantee, embody the entire agreement and understanding between the parties hereto with respect to the specific matters
set forth herein and supersede all prior agreements and understandings relating to the subject matter hereof. 
 This Fee Letter shall be governed by and
construed in accordance with the laws of the State of New York. Each of the parties hereby irrevocably waives all right to trial by jury in any action, proceeding or counterclaim (whether based on contract, tort or otherwise) arising out of or
relating to this Fee Letter or the transactions contemplated hereby. 
 This Fee Letter may be executed in any number of counterparts, each of which shall
be an original, and all of which, when taken together, shall constitute one agreement. Delivery of an executed signature page of this Fee Letter by facsimile or electronic mail transmission shall be effective as delivery of a manually executed
counterpart hereof. 
 The Fee Letter shall become effective as of the time of execution of the Credit Agreement and which is subject of the guarantee under
the Guarantee (the “Effective Date”) and shall remain effective until the expiration or termination of the Guarantee, and provided that the Company shall remain liable following the termination hereof for accrued and unpaid Fees. 

This Fee Letter may not be amended or any provision hereof waived or modified except by an instrument in writing signed by the Company and Kirin.

 (b) If the BANK determines at any time that any applicable law or governmental rule,
regulation, guideline, or order concerning capital adequacy, reserves, or similar requirements, or any change in interpretation or administration thereof by any GOVERNMENTAL AUTHORITY will have the effect of increasing the cost to the BANK or the
amount of capital required or expected to be maintained by the BANK as a result of the making or continuance of the LOANS, then the BORROWER agrees to pay to the BANK, upon its written demand therefor, such additional amounts as shall be required to
compensate the BANK for such increased costs. The BANK, upon determining that any additional amounts will be payable to the BANK pursuant to this paragraph, will give prompt written notice thereof to the BORROWER, which notice shall show in
reasonable detail the basis for calculation of such additional amounts, although the failure to give any such notice shall not release or diminish the obligations of the BORROWER to pay additional amounts pursuant to this paragraph. 

(c) If any present or future applicable law, rule, or regulation or any change therein or in the interpretation or administration thereof by
any GOVERNMENTAL AUTHORITY charged with the interpretation or administration thereof, or compliance by the BANK with any request or directive of any such GOVERNMENTAL AUTHORITY, whether or not having the force of law, results in an increase of the
cost to the BANK of making, renewing, or maintaining any LOAN, or reduces the amount of any sum receivable by the BANK under any LOAN, in the reasonable judgment of the BANK, then, upon demand by the BANK, the BORROWER agrees to pay to the BANK such
additional amount or amounts as would compensate the BANK for such increased cost or reduction. The BANK’s computation of such amount or amounts shall be binding on the BORROWER absent manifest error.

 SECTION 8.08 COSTS, EXPENSES. AND TAXES. The BORROWER hereby agrees to pay on demand after
giving borrowing written notice of the demand (i) all reasonable out-of-pocket expenses incurred by the BANK and its affiliates, including the reasonable fees,

provisional or final) at any time held, and other indebtedness at any time owing by the BANK to or for the credit or the account of the BORROWER against any and all of the obligations of the BORROWER now or hereafter existing under the AGREEMENT or
the NOTE or any other LOAN DOCUMENT, irrespective of whether or not the BANK shall have made any demand under this AGREEMENT or such other LOAN DOCUMENT and although such obligations may be unmatured. The BANK agrees promptly to notify the BORROWER
after any such set off and application, provided that the failure to give such notice shall not affect the validity of such set off and application. The rights of the BANK under this SECTION 8.10 are in addition to other rights and remedies
(including, without limitation, other rights of set off) which the BANK may have.

SECTION 8.13 HEADINGS. ARTICLE and SECTION headings in this AGREEMENT are for the convenience of reference only and shall not constitute a part of
the applicable LOAN DOCUMENTS for any other purpose.
