	3.	Maturity. The Principal amount due under this Note shall become immediately due and payable to Holder automatically and without further action or notice on the part of

	4.	 Prepayment. All payments due under this Note shall be made by check payable to HOLDER. The Company, at its option, may prepay this Note at any time in whole

 2 

	 	 
part without premium or penalty, subject to HOLDER’s right to convert the sums due hereunder to equity as set forth in paragraph (5) herein.

  

	5.	Collateral. (a) In order to secure (i) the due and punctual payment of all monetary obligations hereunder of the Company to Holder and any reasonable costs and expenses
(including, but not limited to, all legal fees and expenses) of collection or enforcement of any such obligations and (ii) the due and punctual payment of any costs and expenses incurred in connection with the realization of the security of which
this Note provides and any reasonable costs and expenses (including, but not limited to, all legal fees and expenses) incurred in connection with any proceedings to which this Note may give rise (collectively referred to herein as
“Liabilities”), the Company hereby transfers, assigns, grants, bestows, sells, conveys and pledges to Holder a first priority security interest in the Collateral (as hereinafter defined), which security interest shall remain in full force
and effect until all of the Liabilities shall have been paid in full to Holder. 

  
 (b) For purposes of this Note, “Collateral” shall mean all of the Company’s right, title and interest in and to all of its tangible personal property and intangible property (including, without
limitation, the Company’s cash on hand, contract rights, securities, accounts receivables, equipment, inventory, trademarks, copyrights and other intellectual property, wherever located; BUT EXCLUDING: (i) the
Company’s rights in that certain Cooperative Research and Development Agreement for Non-Hodgkin Lymphoma Therapeutic Cancer Vaccine between the Company and the National Cancer Institute (as hereafter amended and supplemented), (ii) and the
Company’s rights arising from and relating to Non-Hodgkin Lymphoma Therapeutic Cancer Vaccine, and (iii) the 

  

 3 

 
Company’s grant receivable from the National Institutes of Health; in each case, (x) whether tangible or intangible; (y) all and any proceeds from any
sale, lease, license or other disposition thereof, and (z) all proceeds and products thereof). 
  
 (c) The Company hereby grants Holder a limited power of attorney to prepare and file appropriate UCC-1 financing statements (as secured party) in
appropriate jurisdictions to evidence and publish the liens created by this Note. 
  
 (d) Except as contemplated by this Note and except as specifically set forth in the immediately following proviso, the Company shall not encumber or grant a security interest in any of the Collateral without the prior
written consent of Holder and, other than the grant of the security interest contemplated hereby, the Collateral pledged by the Company hereunder is, and will be, owned by Maker free and clear of all liens and encumbrances; provided that, by
Holder’s acceptance of this Note, Holder hereby agrees that the indebtedness evidenced by this Note (and the security interest granted and lien created hereby) shall be subordinated in right of payment to all existing secured debts of the
Company outstanding on the date of issuance of this Note, plus payment in full in cash of up to $5,000,000 aggregate principal amount of indebtedness to third parties (other than Accentia, Inc. and/or its affiliates) and accrued interest thereon as
may be outstanding from time to time after the date hereof (“Senior Debt”). Such terms of subordination shall be the terms reasonably requested by the lender(s) of such Senior Debt and, in connection therewith, Holder shall execute and
deliver such subordination 

  

 4 

 
agreement and/or intercreditor agreement as may be requested by such lender of Senior Debt. 
  

	6.	Option to Convert To Equity. (a) At any time prior to the Maturity Date, or prior to payment of the outstanding sums due under this Note, HOLDER may elect to convert the
outstanding balance due, including accrued and unpaid interest, into either:  

  

	 	(i)	 Common Stock of the Company, which is restricted as to transfer under state and federal securities laws, at the rate of $0.50 per share of Company Common Stock. The
number of shares of Company Common Stock issuable upon conversion of this Note and the above conversion price shall be subject to adjustment as follows: In case the Company shall (A) pay a dividend in Company Common Stock or make a distribution in
Company Common Stock, (B) subdivide its outstanding Company Common Stock, (C) combine its outstanding Company Common Stock into a smaller number of shares of Company Common Stock, or (D) issue by reclassification of Company Common Stock other
securities of the Company, then the conversion price and the number of shares of Company Common Stock issuable open conversion of this Note immediately prior thereto shall be proportionately adjusted so that the Holder shall be entitled to receive
the kind and number of shares or other securities of the Company which it would have owned or would have been entitled to receive immediately after the happening of any of the events described above had this Note been converted at the conversion
price in effect immediately prior to the happening of such event or any record date with respect thereto and where adjustment made pursuant to this 

  

 5 

	 	 
Section 5(a)(i) shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event. For the
purpose of this Section 5(a)(i), the term “Company Common Stock” shall mean (i) the class of stock designated as the Common Stock of the Company at the date of this Note, or (ii) any other class of stock resulting from successive changes
or reclassifications of such Common Stock consisting solely of changes in par value, or from par value to no par value, or from no par value to par value; OR 

  

	 	(ii)	 Common Stock of Accentia, Inc., a Florida corporation (“Accentia”), which is restricted as to transfer under state and federal securities laws, equal to
the Principal and accrued and unpaid interest thereon being converted based upon the following Accentia Common Stock value: (A) if Accentia’s Common Stock is publicly traded, the value of a share of Accentia Common Stock shall be an amount
equal to the IPO offering price thereof, before discount or commission, as stated in the final prospectus for Accentia Common Stock or in the alternative or (B) if Accentia’s Common Stock is not publicly trading, the value of a share of
Accentia Common Stock shall be determined by appraisal by an independent nationally recognized valuation firm selected by the Board of Directors of Accentia. Such appraisal determination shall be set forth in reasonable detail in a written notice to
Holder and, absent manifest error or fraud, shall be binding on Accentia and Holder; provided, however, that the Holder shall have the right to object to such determination by providing written notice (the “Objection Notice”) to Accentia
within five (5) business days of Holder’s receipt of such written notice of such determination. Provided Holder delivers the Objection Notice 

  

 6 

	 	 
within such five (5) business day period, then, within a further period of ten (10) business days (the “Settlement Period”), Accentia and Holder
and, if desired, their accountants will attempt to resolve in good faith any disputed items and reach a written agreement with respect thereto. Failing such resolution, the unresolved disputed items will be referred for final binding resolution to
an independent nationally recognized firm of certified public accountants (the “Sole Arbiter”) mutually acceptable to Accentia, on the one hand, and Holder, on the other hand. In the event that Accentia and Holder are unable to select the
Sole Arbiter within five (5) business days following the end of the Settlement Period, then each of Accentia and Holder shall have an additional five (5) business days to select (and provide written notice of such selection to the other) an
independent nationally recognized firm of certified public accountants. Each such firm shall be referred to, respectively, as the “First Arbiter” (selected by Accentia) and the “Second Arbiter” (selected by Holder). Within ten
(10) business days following the selection of the First Arbiter and the Second Arbiter, the First Arbiter and the Second Arbiter shall select (and provide written notice to Accentia and Holder of such selection) a third independent nationally
recognized firm of certified public accountants (the “Third Arbiter”). For purposes of this Agreement, the “Arbiter” shall mean (1) the Sole Arbiter or (2) in the case that Accentia and Holder cannot agree upon the Sole Arbiter,
the First Arbiter, Second Arbiter and Third Arbiter collectively; provided that if either Holder or Accentia fails to select the First Arbiter or the Second Arbiter, respectively, then the Sole Arbiter (and thus the “Arbiter”) shall be
deemed to be the First Arbiter in the case where Holder failed to make the selection and the Second Arbiter in the case where Accentia failed to 

  

 7 

	 	 
make the selection. In the case where the Arbiter consists of a First Arbiter, Second Arbiter and Third Arbiter, the decision of a majority of the First
Arbiter, Second Arbiter and Third Arbiter shall constitute the decision of the Arbiter hereunder. The fees and expenses of the Arbiter shall be borne by the non-prevailing party. In making such determination (the “Arbiter’s
Determination”), the Arbiter shall determine only those items in dispute and may not assign a value to any disputed item greater than the greatest value for such sum claimed by either party or less than the lowest value for such item claimed by
either party. The Arbiter’s Determination shall be (I) in writing, (II) furnished to Accentia and Holder as soon as practicable after the items in dispute have been referred to the Arbiter (but in no event later than ten (10) business days
after such referral), (III) made in accordance with generally accepted accounting principles consistently applied, and (IV) non-appealable. The number of shares Accentia Common Stock issuable open conversion of this Note shall be subject to
adjustment as follows: In case Accentia shall (w) pay a dividend in Accentia Common Stock or make a distribution in Accentia Common Stock, (x) subdivide its outstanding Accentia Common Stock, (y) combine its outstanding Accentia Common Stock into a
smaller number of shares of Accentia Common Stock, or (z) issue by reclassification of Accentia Common Stock other securities of Accentia, then the conversion price and the number of shares issuable open conversion of this Note immediately prior
thereto shall be proportionately adjusted so that the Holder shall be entitled to receive the kind and number of shares or other securities of Accentia which it would have owned or would have been entitled to receive immediately after the happening
of any of the events 

  

 8 

	 	 
described above had this Note been converted been exercised at the conversion price immediately prior to the happening of such event or any record date with
respect thereto. Any adjustment made pursuant to this Section 5(a)(ii) shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such event. For the purpose of this Section 5(a)(ii), the
term “Accentia Common Stock” shall mean (xx) the class of stock designated as the Common Stock of Accentia at the date of this Note, or (yy) any other class of stock resulting from successive changes or reclassifications of such Common
Stock consisting solely of changes in par value, or from par value to no par value, or from no par value to par value. 

  

	 	(b)	Such exercise shall be made by irrevocable written notice (accompanied with this Note), addressed to the Company at its Executive Offices at 8500 Evergreen Blvd. Minneapolis MN
55433 with notice to Accentia at its Executive Offices at 5310 Cypress Center Drive, Suite 101, Tampa, Florida 33609. 

  

	7.	 Miscellaneous. Notwithstanding any provision herein or in any documents or instrument now or hereafter securing this Note, the total liability for payments
in the nature of interest shall not exceed the limits now or at any time in the future imposed by the applicable laws of the State of New York. This Note shall be governed by, and construed in accordance with, the laws of the State of New York
applicable to agreements entered into and to be performed entirely within such State. Andrews Alexander Wise & Co. (AAW) has been granted compensation in the form of the repricing of certain Warrants previously issued to AAW for its efforts in
assisting BioVest in informing Noteholders of 

  

 9 

	 	 
their rights to elect to restructure their investment to accept this form of Amended Promissory Note.
