time to time. Biovest shall convert all non-U.S. Dollar sales to U.S. Dollars using the average exchange rates quoted in the Wall Street Journal for the final day of each month in the relevant period for which the Royalty is being paid. In the

country into an account to be designated by Biovest. 
 4.5 Taxation of Payments. 
 (a) Insofar as any payment that is due under this Agreement is subject to any tax, duty, levy, or other government imposition, the Party receiving the
payment agrees to bear 

  

 3 

 
any and all such taxes, duties, levies or impositions. Each Party hereby authorizes the other Party to withhold such taxes, duties, levies or impositions
from the payments in accordance with this Agreement if Biovest or Valens Offshore is required to do so under the laws of the United States or any country in the Territory where such taxes, duties, levies or impositions are payable. Whenever a Party
deducts such tax, duty, levy or imposition from any payments due, then it shall furnish the other Party with a certificate showing the payment of thereof to the United States or any country in the Territory. 
 (b) In the event any payments which are due under this Agreement are subject to value added taxation by any government, then the Party receiving the
payment shall bear such value added tax in full and the Party making the payment shall be reimbursed therefor. If appropriate, the Party receiving payment may add such value added taxes to its royalty accounts, provided such value added taxes are
credited against the other Party’s value added tax debt and the other Party is reimbursed in full with respect thereto. Notwithstanding anything herein to the contrary, the Party making the payment shall have no liability for any value added
tax directly or indirectly relating thereto. 
 (c) In the event any payment is subject to a withholding or other income tax in any country
in the Territory, promptly following becoming aware of the applicability of any such tax, the Party making the payment shall so advise the other Party. The Party receiving the payment shall have the right to contest such tax with the appropriate
governmental body any such proposed withholding and the other Party shall provide, at receiving Party’s expense, reasonable cooperation in any such contest. The Parties shall provide each other with such receipts or other evidence of any tax
withheld as is necessary to claim any credit or deduction available to it in other jurisdictions. Payments shall only be reduced for withholding taxes imposed by the jurisdiction out of which the payment is directly made. 
 4.6 Interest. All payments due hereunder that are not paid when due and payable as specified in this agreement shall bear interest at an annual
rate equal to the prime rate (“Prime Rate”) for U.S. dollar deposits in effect from time to time, as published daily in the Wall Street Journal plus 5%, compounded monthly from the date due until paid, or at such lower rate of interest as
shall then be the maximum rate permitted by applicable law. 
 4.7 Right to Documentation. Upon request, Valens Offshore shall have
the right to request reasonable documentation of Biovest’s calculations to determine Biovest’s Net Sales and/or License Revenue and to request discussion of such calculations with appropriate representatives of Biovest. 
 4.8 Records Retention. Biovest, its assignees and Affiliates shall keep complete and accurate records pertaining to Net Sales and License revenue
for a period of three (3) calendar years after the year in which such sales occurred, and in sufficient detail to permit Valens Offshore to confirm the accuracy of Royalty calculations hereunder. Such records shall be available at all

Affiliates or Licensees (as applicable), at reasonable times and 

  

 4 

 
upon reasonable notice, to examine those records and all other material documents relating to or relevant to Net Sales and License Revenue in the possession
or control of Biovest, its Affiliates or Licensees, for a period of three (3) years after such royalties have accrued, as may be necessary to: (i) determine the correctness of any report or payment made under this Agreement; or
(ii) obtain information as to the Royalties payable for any calendar quarter in the case of Biovest’s or its Affiliate’s failure to report or pay pursuant to this Agreement. Said accountant shall not disclose to Valens Offshore any
information other than information relating to said reports, royalties, and payments. Results of any such examination shall be made available to both Parties. Valens Offshore shall bear the full cost of the performance of any such audit, unless such
audit demonstrates underpayment of royalties by Biovest of more than ten percent (10%) from the amount of the original royalty payment made by Biovest. In such event, Biovest shall bear the full cost of the performance of such audit.

 ARTICLE 5 — CONFIDENTIALITY 
 5.1 Use of Name. Valens Offshore agrees not to use directly or indirectly Biovest’s name without Biovest’s prior written consent except as part of its required filings or in connection with a

any and all such taxes, duties, levies or impositions. Each Party hereby authorizes the other Party to withhold such taxes, duties, levies or impositions
from the payments in accordance with this Agreement if Biovest or Valens US is required to do so under the laws of the United States or any country in the Territory where such taxes, duties, levies or impositions are payable. Whenever a Party
deducts such tax, duty, levy or imposition from any payments due, then it shall furnish the other Party with a certificate showing the payment of thereof to the United States or any country in the Territory. 
 (b) In the event any payments which are due under this Agreement are subject to value added taxation by any government, then the Party receiving the
payment shall bear such value added tax in full and the Party making the payment shall be reimbursed therefor. If appropriate, the Party receiving payment may add such value added taxes to its royalty accounts, provided such value added taxes are
credited against the other Party’s value added tax debt and the other Party is reimbursed in full with respect thereto. Notwithstanding anything herein to the contrary, the Party making the payment shall have no liability for any value added
tax directly or indirectly relating thereto. 
 (c) In the event any payment is subject to a withholding or other income tax in any country
in the Territory, promptly following becoming aware of the applicability of any such tax, the Party making the payment shall so advise the other Party. The Party receiving the payment shall have the right to contest such tax with the appropriate
governmental body any such proposed withholding and the other Party shall provide, at receiving Party’s expense, reasonable cooperation in any such contest. The Parties shall provide each other with such receipts or other evidence of any tax
withheld as is necessary to claim any credit or deduction available to it in other jurisdictions. Payments shall only be reduced for withholding taxes imposed by the jurisdiction out of which the payment is directly made. 
 4.6 Interest. All payments due hereunder that are not paid when due and payable as specified in this agreement shall bear interest at an annual
rate equal to the prime rate (“Prime Rate”) for U.S. dollar deposits in effect from time to time, as published daily in the Wall Street Journal plus 5%, compounded monthly from the date due until paid, or at such lower rate of interest as
shall then be the maximum rate permitted by applicable law. 
 4.7 Right to Documentation. Upon request, Valens US shall have the
right to request reasonable documentation of Biovest’s calculations to determine Biovest’s Net Sales and/or License Revenue and to request discussion of such calculations with appropriate representatives of Biovest. 
 4.8 Records Retention. Biovest, its assignees and Affiliates shall keep complete and accurate records pertaining to Net Sales and License revenue
for a period of three (3) calendar years after the year in which such sales occurred, and in sufficient detail to permit Valens US to confirm the accuracy of Royalty calculations hereunder. Such records shall be available at all reasonable
times for inspection by Valens US or its representatives for verification of Royalty payments or compliance with other aspects of this Agreement. 
 4.9 Audit Request. At the request of Valens US, Biovest its Affiliates and Licensees shall permit an independent, certified public accountant appointed by Valens US and acceptable to Biovest or its Affiliates or Licensees (as
applicable), at reasonable times and upon reasonable 

  

 4 

 
notice, to examine those records and all other material documents relating to or relevant to Net Sales and License Revenue in the possession or control of
Biovest, its Affiliates or Licensees, for a period of three (3) years after such royalties have accrued, as may be necessary to: (i) determine the correctness of any report or payment made under this Agreement; or (ii) obtain
information as to the Royalties payable for any calendar quarter in the case of Biovest’s or its Affiliate’s failure to report or pay pursuant to this Agreement. Said accountant shall not disclose to Valens US any information other than
information relating to said reports, royalties, and payments. Results of any such examination shall be made available to both Parties. Valens US shall bear the full cost of the performance of any such audit, unless such audit demonstrates
underpayment of royalties by Biovest of more than ten percent (10%) from the amount of the original royalty payment made by Biovest. In such event, Biovest shall bear the full cost of the performance of such audit.

 5.1

 (a) Senior Officials. The Parties recognize that a bona fide dispute as to certain matters may from time to time arise during the term of this
Agreement which relates to either Party’s rights and/or obligations hereunder. In the event of the occurrence of such a dispute, either Party may, by notice to the other Party, have such dispute referred to their respective senior officials

 In the event the designated senior officials are not able to resolve such dispute within the

 (b) In the event of any dispute, difference
or question arising between the Parties in connection with this Agreement, the construction thereof, or the rights, duties or liabilities of either Party, and which dispute cannot be amicably resolved by the good faith efforts of both Parties, then
