	4.5	Relationship to JHU License and Payment of Royalties to JHU. The Parties acknowledge that, notwithstanding any terminology used in this Agreement to the contrary, BIOVEST is

	4.11	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 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 REVIMMUNE is required to do so under the laws of the United States. 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. 
 (b) In the event any payments which are due to 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 therefore. If appropriate, the Party receiving payment may add such value 

  

 7 








 
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 to thereto. 
 (c) In the event any payment is subject to a withholding or other income tax 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 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. 
  

	4.12	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 2%, 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. 

  

	4.13	Right to Documentation. Upon request, REVIMMUNE shall have the right to request reasonable documentation of BIOVEST’s Sublicensed Royalty calculations to determine
BIOVEST’s Net Sales and/or Sublicensee Net Sales for the Sublicensed Products and to request discussion of such calculations with appropriate representatives of BIOVEST. 

  

	4.14	Records Retention. BIOVEST, its Sublicensee shall keep complete and accurate records pertaining to the sale of Sublicensed Products in the Territory and covering all

the Sublicensed Royalties payable for any calendar quarter in the case of BIOVEST’s or sublicense’s failure to 



  

 8 








 
report or pay pursuant to this Agreement. Said accountant shall not disclose to REVIMMUNE any information other than information relating to said reports,
royalties, and payments. Results of any such examination shall be made available to both Parties. REVIMMUNE 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.

action. The costs and expenses of any such action (including fees of attorneys and other professionals) shall be borne by the Party instituting the action, or, if the Parties elect to cooperate in instituting and maintaining such action, such costs
and expenses shall be borne by the Parties in such proportions as they may agree in writing. Each Party shall execute all necessary and proper documents and take such actions as shall be appropriate to allow the other Party to institute and
prosecute such infringement actions. Any award paid by third parties as a result of such an infringement action (whether by way of settlement or otherwise) shall be paid to the Party who instituted and maintained such action, or, if both Parties

(iii) the expiration of the last-to-expire of the patent claims included in the Sublicensed Rights. The Term shall be automatically extended by successive extension terms (the “Extension Terms”) of one (1) year each unless either
party gives written notice of its election not to extend the term at least ninety (90) days prior to the expiration of the Initial Term or of any Extension Term. Notwithstanding the forgoing, the Sublicense shall terminate upon the filing of a
petition in bankruptcy by or against Biovest or the filing of a petition for liquidation or receivership of Biovest. Notwithstanding the forgoing, the Sublicense shall terminate upon any pledge or granting of any lien or security interest in the
Sublicense or any interest under the Sublicense without the prior written consent of REVIMMUNE. Further, the Sublicense shall terminate in the event that BIOVEST does not file an IND which is accepted for filing by the Food and Drug Administration
for an indication which upon approval will result in royalties being paid to Revimmune under this Sublicense within two (2) years from the date hereof. 

  

	8.2	Breach. Failure by either Party to comply with any of the material obligations contained in this Agreement shall entitle the other Party to give to the Party in default
notice specifying the nature of the default and requiring it to cure such default. If such default is not cured within one hundred twenty (120) days after the receipt of such notice (or, if such default cannot be cured within such 120 day
period, if the Party in default does not commence and diligently continue actions to cure such default), the notifying Party shall be entitled, without prejudice to any of its other rights conferred on it by this Agreement, in addition to any other
remedies available to it by law or in equity, to terminate this Agreement by giving written notice to take effect within thirty (30) days after such notice unless the defaulting Party shall cure such default within said thirty (30) days.
The right of either Party to terminate this Agreement, as hereinabove provided, shall not be affected in any way by its waiver or failure to take action with respect to any previous default. 

  

	8.3	Termination of Sublicenses. Upon any termination of this Agreement, all sublicenses granted by BIOVEST under this Agreement shall terminate simultaneously, subject,
nevertheless, to Section 8.4. 

  

	8.4	Effect of Termination. Upon the termination of this Sublicense Agreement, BIOVEST and its sublicensees shall promptly: (i) return to REVIMMUNE all relevant records,
materials or confidential information of REVIMMUNE concerning the REVIMMUNE Licensed Rights relating to such Sublicensed Product in the possession or control of BIOVEST or its sublicensees; (ii) assign to REVIMMUNE, or REVIMMUNE’s
designee, its registrations with governmental health authorities, licensees, and approvals of such Sublicensed Product in the Territory and (iii) cease and desist from developing, promoting, marketing, selling or commercializing any Sublicensed
Product (except to the extent reasonably necessary to liquidate existing inventories and fulfill then-existing orders and obligations).

	8.5	Surviving Rights. Termination of this Agreement shall not terminate BIOVEST’s obligation to comply with Articles 4, 5, 6 and 7 hereunder. 

  

	8.6	Accrued Rights, Surviving Obligations. Termination, relinquishment or expiration of this Agreement for any reason shall be without prejudice to any rights which shall have
accrued to the benefit of either Party under this Agreement prior to such termination, relinquishment or expiration. Such termination, relinquishment or expiration shall not relieve either Party from obligations which are expressly indicated to
survive termination or expiration of this Agreement. 

 ARTICLE 9—MISCELLANEOUS PROVISIONS 
  

	9.1	Relationship of Parties. Nothing in this Agreement is or shall be deemed to constitute a partnership, agency, employee or joint venture relationship between the Parties. No
Party shall incur any debts or make any commitments for the other, except to the extent, if at all, specifically provided herein.

	9.3	Assignment. Except as otherwise provided herein, neither this Agreement nor any interest hereunder shall be assignable by BIOVEST without the prior written consent of
REVIMMUNE; provided, however, that either Party may assign this Agreement to any wholly-owned subsidiary or to any successor by merger or sale of substantially all of its assets to which this Sublicense Agreement relates in a manner such that the
assignor shall remain liable and responsible for the performance and observance of all its duties and obligations hereunder. This Sublicense Agreement shall be binding upon the successors and permitted assigns of the parties and the name of a Party
appearing herein shall be deemed to include the names of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this Agreement. Any assignment not in accordance with this Section 10.3 shall be
void. Biovest shall not pledge or permit any lien or security interest to be placed against the Sublicense or any interest hereunder without the prior written consent of REVIMMUNE. Any pledge, lien or security interest not in accordance with this
Section 10.3 shall be void. 

  

	9.4	Further Actions. Each Party agrees to execute, acknowledge and deliver such further instructions, and to do all such other acts, as may be necessary or appropriate in order
to carry out the purposes and intent of this Agreement. 

  

	9.5	 Force Majeure. Neither Party shall be liable to the other for loss or damages nor shall have any right to terminate this Agreement for any default or delay
attributable to any act of God, flood, fire, explosion, strike, lockout, labor dispute, shortage of raw materials, casualty, accident, war, revolution, civil commotion, act of public enemies, blockage or embargo, injunction, law, order,
proclamation, regulation, ordinance, demand or requirement of any government or subdivision, authority or representative of any such government, or any other cause beyond the reasonable control of such Party, if the Party 



  

 14 









	 	 
affected shall give prompt notice of any such cause to the other Party. The Party giving such notice shall thereupon be excused from such of its obligations
hereunder as it is thereby disabled from performing for so long as it is so disabled and for thirty (30) days thereafter. Notwithstanding the foregoing, nothing in this Section 10.5 shall excuse or suspend the obligation to make any
payment due hereunder in the manner and at the time provided. 


  

	9.6	No Trademark Rights. Except as otherwise provided herein, no right, express or implied, is granted by this Agreement to use in any manner the name “BIOVEST” or
“REVIMMUNE” or any other trade name or trademark of the other party in connection with the performance of this Agreement. 

  

	9.7	Public Announcements. Except as required by law, neither Party shall make any public announcement concerning this Agreement or the subject matter hereof without the prior
written consent of the other. In the event of a legally-required public announcement, the Party making such announcement shall provide the other with a copy of the proposed text prior to such announcement.

officer of each Party. This Agreement may be executed in a series of counterparts, all of which, when taken together, shall constitute one and the same instrument.

	9.11	Dispute Resolution. 

 (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 designated below or their successors, for attempted resolution by good faith negotiations within thirty
(30) days after such notice is received. Said designated senior officials are as follows: 
  

			
	For BIOVEST:	  	Chairman of the Audit Committee
	For REVIMMUNE:	  	Francis E. O’Donnell, Jr., M.D. Managing Member

 In the event the designated senior officials are not able to resolve such dispute within the
thirty (30) day period, either Party may invoke the provisions of Section 10.11(b). 
 (b) Arbitration. 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 such dispute shall be resolved by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association. The arbitration panel shall be composed of three arbitrators, one
of whom shall be chosen by REVIMMUNE, one by BIOVEST, and the third by the two so chosen. If both or either of BIOVEST or REVIMMUNE fails to choose an arbitrator or arbitrators within fourteen (14) days after receiving notice of commencement of
arbitration or if the two arbitrators fail to choose a third arbitrator within fourteen (14) days after their appointment, the then President of the American Arbitration Association shall, upon the request of both or either of the Parties to
the arbitration, appoint the arbitrator or arbitrators required to complete the board or, if he shall decline or fail to do 

  

 16 








 
so, such arbitrator or arbitrators shall be appointed by the American Arbitration Association. The decision of the arbitrators shall be by majority vote and,
at the request of either Party; the arbitrators shall issue a written opinion of findings of fact and conclusions of law. Costs shall be borne as determined by the arbitrators. Unless the Parties to the arbitration shall otherwise agree to a place
of arbitration, the place of arbitration shall be at Tampa, Florida, U.S.A. The arbitration award shall be final and binding upon the Parties to such arbitration and may be entered in any court having jurisdiction. 
  

	9.12	Governing Law. This Agreement shall be governed by and interpreted in accordance with the laws of the State of FLORIDA. 

  

	9.13	Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision
of this Agreement is held to be prohibited by or invalid under applicable law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of this Agreement. 


 

	9.14	Entire Agreement of the Parties. This Agreement constitutes and contains the entire understanding and agreement of the Parties and cancels and supersedes any and all prior
negotiations, correspondence, understandings and agreements, whether oral or written, between the Parties respecting the subject matter hereof.
