or the receipt of any proceeds of the Collateral by Secured Party, after all of the Indebtedness with appropriate interest and all costs and expenses of Secured Party with respect to the possession and sale of the Collateral have been paid in full
as appropriate, the surplus, if any, shall be paid to Borrower by Secured Party, and any Collateral remaining shall be transferred and reassigned to Borrower by Secured Party; and in the event of a deficiency, there shall be due from Borrower and
Borrower shall immediately pay to Secured Party the difference between the amounts received by Secured Party and the remaining sum secured hereby, plus all costs and expenses of Secured Party in repossessing, transporting, repairing, storing,
selling or otherwise handling the Collateral pursuant to such sale or other disposition.

 Section 7. Miscellaneous. 
 (a) Borrower authorizes Secured
Party at Borrower’s expense to file any financing statement or statements relating to the Collateral (without Borrower’s signature thereon) which Secured Party deems appropriate, and Borrower appoints Secured Party as Borrower’s
attorney-in-fact to execute any such financing statement or statements in Borrower’s name and to perform all other acts which Secured Party deems appropriate to perfect and to continue perfection of the Security Interest. 

(b) Without limiting any other right of Secured Party, whenever Secured Party has the right to declare any Indebtedness to be immediately
due and payable (whether or not it has so declared), Secured Party may set off against the Indebtedness all monies then owed to the Borrower by Secured Party in any capacity whether due or not and Secured Party shall be deemed to have exercised its
right to set off immediately at the time its right to such election accrues. 
 (c) Upon Borrower’s failure to perform any
of its duties hereunder, Secured Party may but it shall not be obligated to perform any of such duties and Borrower shall forthwith upon demand reimburse Secured Party for any expense incurred by Secured Party in so doing. 

(d) No delay or omission by Secured Party in exercising any right hereunder or with respect to any Indebtedness shall operate as a waiver
of that or any other right, and no single or partial exercise of any right shall preclude Secured Party from any other or further exercise of any other right or remedy. Secured Party may cure any default by Borrower in any reasonable manner without
waiving the default so cured and without waiving any other prior or subsequent default by Borrower. 
 (e) Secured Party shall
have no obligation to take and Borrower shall have the sole responsibility for taking any steps to preserve rights against all prior parties. Borrower waives presentment for payment, notice of protest, notice of nonpayment, notice of dishonor and
protest of any instrument at any time held by Secured Party on which Borrower is in any way liable and, if waivable, waives notice of any other action taken by Secured Party.

thereunder. Whenever possible, each provision of this Agreement shall be interpreted to be effective and valid under applicable law. If any provision of this Agreement is prohibited by or invalid under applicable law, the provision shall be

WHEREAS, pursuant to the terms of a Secured Promissory Note (the “Note”) and Security Agreement (the “Security
Agreement”), to be entered into on or about June 13, 2011, the Company is pledging as collateral twelve million shares of the common stock of Biovest International, Inc. owned by the Company (the “Collateral”) to Secured Party;
and 
 WHEREAS, the Company and Secured Party desire to establish an escrow account with the Agent into which the Company shall
deposit the Collateral in accordance with the terms of the Security Agreement. 
 NOW, THEREFORE, in consideration of the mutual
promises herein contained and intending to be legally bound, the parties hereby agree as follows: 
 1. Appointment of
Agent. The Company and Secured Party hereby appoint the Agent as escrow agent in accordance with the terms and conditions set forth herein, and the Agent hereby accepts such appointment. 

2. Delivery of Collateral. The common stock to be held as Collateral pursuant to the Security Agreement will be delivered by the
Company to the Agent, along with a Stock Power endorsed in blank to Agent, as agent for the Company. 
 3. Agent to Hold and
Disburse Collateral. The Agent will hold the Collateral in escrow for the benefit of the Secured Party and the Company. The Collateral shall be released pursuant to the terms of this Escrow Agreement, as follows: 

3.1 Release upon Payment of Note. Upon payment in full of all obligations due to Secured Party from Company on account of the
Note, Agent shall release the Collateral to the Company, provided that the Secured Party and the Company (or their counsel) have confirmed to the Agent in writing that all conditions for the release of the Collateral have occurred. In the event of
partial payment of the principal amount of the Note whether by pre-payment or by conversion into shares of common stock as provided in the Note, the number of shares that is proportionate to the reduction in the principal amount of the Note shall be
released by the Agent and returned to the Company. 

 3.2 Release Upon Event of Default. In the event of the occurrence of an Event of
Default under the Note or Security Agreement, which Event of Default shall not have been cured (if such Event of Default is curable), the Agent shall release the Collateral to the Secured Party to be held and dealt with in accordance with the terms
of the Security Agreement, provided that the Secured Party and the Company (or their counsel) have confirmed to the Agent in writing that an Event of Default has occurred and that Secured Party is entitled to the Collateral. 

3.3 In connection with any actions with respect to the Collateral to be taken by the Agent under this Section 3, the Agent may rely
conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel (including counsel chosen by the Agent), statement, instrument, report or other paper or document (not only as to its due
execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information therein contained), which is believed by the Agent to be genuine and to be signed or presented by any person purporting to
be the proper person or persons. In the event of any dispute, action or claim with respect to this Agreement or any asserted claim in or to the Collateral held by Agent hereunder, Agent shall be entitled to deposit the Collateral into a court of
competent jurisdiction and to file an action in the nature of interpleader to allow said claim or dispute to be resolved. 
 4.
Exculpation and Indemnification of Agent. 
 4.1 The Agent shall have no duties or responsibilities other than those
expressly set forth herein. The Agent shall have no duty to enforce any obligation of any person to make any payment or delivery, or to direct or cause any payment or delivery to be made, or to enforce any obligation of any person to perform any
other act. The Agent shall be under no liability to the other parties hereto or to anyone else by reason of any failure on the part of any party hereto or any maker, guarantor, endorser or other signatory of any document or any other person to
perform such person’s obligations under any such document. Except for amendments to this Agreement made in accordance with the term hereof, and except for written instructions given to the Agent by the Company and Secured Party relating to the
Collateral, the Agent shall not be obligated to recognize any agreement between any of the persons referred to herein, notwithstanding that references thereto may be made herein and whether or not it has knowledge thereof. 

4.2 The Agent shall not be liable to the Company, Secured Party or to anyone else for any action taken or not taken, or any action
suffered by it to be taken or not taken, in good faith and in the exercise of its own best judgment. The Agent may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel
(including counsel chosen by the Agent), statement, instrument, report or other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability of any information
therein contained), which is believed by the Agent to be genuine and to be signed or presented by the proper person or persons. The Agent shall not be bound by any notice or demand, or any waiver, modification, termination or rescission of this
Agreement or any of the terms thereof, unless evidenced by a writing signed by all parties to this Agreement. 

  
 2 

 4.3 The Agent shall not be responsible for the sufficiency or accuracy of the form of, or
the execution, validity, value or genuineness of, any document or property received, held or delivered by it hereunder, or of any signature or endorsement thereon, or for any lack of endorsement thereon, or for any description therein; nor shall the
Agent be responsible or liable to the other parties hereto or to anyone else in any respect on account of the identity, authority or rights of the persons executing or delivering or purporting to execute or deliver any document or property or this
Agreement. The Agent shall have no responsibility with respect to the use or application of any funds or other property paid or delivered by the Agent pursuant to the provisions hereof. 

4.4 The Agent shall have the right to assume, in the absence of written notice to the contrary from the proper person or persons, that a
fact or an event, by reason of which an action would or might be taken by the Agent, does not exist or has not occurred, without incurring liability to the other parties hereto or to anyone else for any action taken or not taken, or any action
suffered by it to be taken or not taken, in good faith and in the exercise of its own best judgment, in reliance upon such assumption. 
 4.5 The Agent will be indemnified and held harmless by the Company and Secured Party from and against any and all expenses, including reasonable attorneys’ fees and disbursements, or loss suffered by
the Agent in connection with any action, suit or other proceeding involving any claim, or in connection with any claim or demand, which in any way, directly or indirectly, arises out of or relates to this Agreement, the services of the Agent
hereunder or the Collateral, except for the Agent’s gross negligence or willful misconduct. Promptly after the receipt by the Agent or notice of any demand or claim or the commencement of any action, suit or proceeding, the Agent shall, if a
claim in respect thereof is to be made against the Company and Secured Party, notify the Company and Secured Party thereof in writing, but the failure by the Agent to give such notice shall not relieve the Company or the Secured Party from any
liability which the Company or the Secured Party may have to the Agent hereunder. 
 4.6 If a dispute ensues between or among
any of the parties hereto which, in the opinion of the Agent, is sufficient to justify its doing so, the Agent shall retain legal counsel of its choice as it reasonably may deem necessary to advise it concerning its obligations hereunder and to
represent it in any litigation to which it may be a part by reason of this Agreement. The Agent shall be entitled to tender into the registry or custody of any court of competent jurisdiction the Collateral and all money or property in its hands
under the terms of this Agreement, and to file such legal proceedings as it deems appropriate, and shall thereupon be discharged from all further duties under this Agreement. Any such legal action may only be brought in the courts located in
Hillsborough County, Florida. In connection with such dispute, the Company and Secured Party shall indemnify the Escrow Agent against its court costs and reasonable attorney’s fees incurred.
