 AGREEMENT 
 NOW, THEREFORE, in consideration of the agreements set forth in the
Payoff Letter and the consummation of the transactions contemplated therein, the agreements set forth in the Assignment of Sale Proceeds and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows: 
 1. Assignor hereby assigns and transfers to Assignee as the absolute owner thereof: 
 (a) Assignor’s right to receive a percentage of the Net Sales and License Revenue within the Territory from any Biovest Biologic Products received by
Biovest (the “Assignee Royalties”) equal to 2.08% (the “Assignee’s Pro Rata Share”) of four percent (4.00%) (the Assignee’s Pro Rata Share of 4.00%, the “Royalty Percentage”),
provided, however, 
 (i) if, on or prior to December 31, 2008, an Analytica Sale (as defined in the Assignment of Sale
Proceeds) has not occurred and the Creditor Parties have not received at least $8,800,000 consisting of (1) an aggregate cash payment from Assignor and/or Analytica, on or after the date hereof, in consideration for the Creditor Parties’
agreement to enter into the Payoff Letter and the other Payoff Documents (as defined in the Payoff Letter) and/or to reduce the obligations under the Term Note (as defined in the Payoff Letter) and/or Minimum Borrowing Note (as defined in the Payoff
Letter), and not in consideration of any other debt or liability of Assignor, Analytica and/or any subsidiary or affiliate of any such entity (such aggregate cash payment, the “Cash Payment”) and/or (2) Conversion Shares issued
pursuant to the optional conversion provision set forth in Section 3.1 of the Term Note and Section 3.1 of the Minimum Borrowing Note, in each case, valued at $1.20 per Conversion Share (the aggregate value of the Conversion Shares, the
“Conversion Amount” and together with the Cash 








 
Payment, the “Qualified Payment”), the Assignor hereby agrees that (A) the Royalty Percentage shall be immediately increased by an
amount equal to Assignee’s Pro Rata Share of two percent (2.00%) (the “Royalty Increase”) which Royalty Increase shall occur automatically without further action on the part of any party and (B) Assignor shall pay to
Assignee, on demand, an amount equal to the Assignee’s Pro Rata Share of the difference between (x) $8,800,000 and (y) the Qualified Payment, if any, actually received by the Creditor Parties (the Assignee’s Pro Rata Share of the
difference between (x) and (y), the “Specified Amount”), which amount shall be due and owing without defense, offset or counterclaim of any kind or nature whatsoever, provided, however, Assignee may elect, in its
sole and absolute discretion, in lieu of requiring payment of the Specified Amount, to (1) further increase the Royalty Percentage (in addition to the Royalty Increase) by a percentage equal to Assignee’s Pro Rata Share of (I) the
difference between $8,800,000 and the Qualified Payment, if any, actually received by the Creditor Parties, divided by (II) 1,000,000, which such further increase of the Royalty Percentage shall occur automatically without further action on the part
of any party, upon Assignee’s delivery to Assignor of notice of such election, or (2) receive from Assignor, and Assignor shall assign and transfer to Assignee or Assignee’s designee, as absolute owner thereof, Assignee’s Pro
Rata Share of one hundred percent (100%) of the capital stock of Analytica (together with all instruments as shall be required by Assignee to effect such transfer) in order for Assignee and the other Creditor Parties to conduct the Analytica
Sale (the “Stock Election”), provided, however, that Assignee may only make the Stock Election if each Creditor Party (or, as applicable, each Creditor Party’s designee) which is a party to those certain
Assignments of Rights Under Royalty Agreement dated as of the date hereof (as amended, modified, supplemented and/or restated from time to time) also makes the Stock Election; or 
 (ii) if an Analytica Sale has occurred on or prior to December 31, 2008, but the Creditor Parties have not received from Assignor and/or Analytica,
on or prior to December 31, 2008, an amount equal to or exceeding $8,800,000, constituting the aggregate amount of the Analytica Proceeds Amount (as defined in the Assignment of Sale Proceeds) and the Qualified Payment, if any, then Assignor
hereby agrees that the Royalty Percentage shall be immediately increased by a percentage equal to the Assignee’s Pro Rata Share of (A) $8,800,000 minus the sum of (1) the Analytica Proceeds Amount actually received by the Creditor
Parties and (2) the Qualified Payment, if any, actually received by the Creditor Parties, divided by (B) 1,000,000, which increase of the Royalty Percentage shall occur automatically without further action on the part of any party; and

 (b) all of Assignor’s other rights and remedies under the Royalty Agreement with respect to the Assignee Royalties. 
 2. In the event Assignor makes the Stock Election and the Creditor Parties receive Net Proceeds (as hereinafter defined) from any such Analytica Sale
equal to or exceeding $8,800,000, the Creditor Parties shall be entitled to all proceeds from such Analytica Sale and Assignor and/or Analytica shall not be entitled to credit for, or refund of, the Qualified Payment, if any. In the event the
Assignor makes the Stock Election and the Creditor Parties receive Net Proceeds from any such Analytica Sale of less than $8,800,000, then Assignor shall pay to Assignee, in cash, on demand, an amount equal to Assignee’s Pro Rata Share of an
amount equal to the difference, if any, between (a) $8,800,000 and (b)(i) the Net Proceeds actually received by the Creditor Parties from such Analytica Sale plus (ii) the Qualified Payment actually received 

  

 2 








 
by the Creditor Parties, if any, which amount, if any, shall be due and owing without defense, offset or counterclaim of any kind or nature whatsoever. The
Creditor Parties hereby agree that any such Analytica Sale shall be consummated pursuant to one or more related arms-length transactions with third party purchaser(s) that are not affiliated with any Creditor Party and Creditor Parties shall receive
no direct or indirect benefit from any such Analytica Sale, other than the Net Proceeds. For purposes hereof, the term “Net Proceeds” shall mean the proceeds received from the Analytica Sale in cash and/or any other consideration paid by
the purchaser in connection with the Analytica Sale, net of (a) customary and reasonable out-of-pocket cash costs, fees and expenses paid or required to be paid in connection therewith and (b) taxes paid or reasonably estimated to be
payable as a result thereof, provided, however, the value of any Net Proceeds not consisting of cash for which there is not a readily available publicly recorded market shall be determined by the Creditor Parties in their commercially
reasonable discretion. 
 3. The Assignee Royalties shall be paid by Biovest to Assignee no later than sixty (60) days following the end
of each calendar quarter (the “Assignee Royalty Payments”). All Assignee Royalty Payments shall be payable in U.S. Dollars by wire transfer in accordance with the wire transfer instructions set forth on Exhibit A hereto.

Agreement and shall have all the rights and remedies granted to Assignor under the Royalty Agreement with respect to the Assignee Royalties and the Assignee Royalty Payments. 
 5. At any time or from time to time, upon Assignee’s written request, each of Assignor and Biovest shall execute and deliver to Assignee such
further documents and do such other acts and things as Assignee may reasonably request in order to further effect the purposes of this Assignment or any schedule, amendment or supplement hereto.

Assignment dated as of the date hereof made by Assignor in favor of the Creditor Parties and certain of their affiliates, the security interest granted to Southwest Bank (so long as such security interest does not cover in any manner whatsoever the
