 ACCENTIA’s principal place of business for at least three (3) years after the end of the License Year to which
they pertain, and will be open at all reasonable times for inspection by a representative of MAYO for verification of royalty statements or compliance with other aspects of this Agreement. The MAYO representative will treat as confidential all
relevant matters and will be a person or firm reasonably acceptable to ACCENTIA. In the event such audit reveals an underpayment by ACCENTIA, ACCENTIA will within thirty (30) days pay the royalty due in excess of the royalty actually paid. In the
event the audit reveals an underpayment by ACCENTIA of more than five percent (5%) of the amount due, ACCENTIA will pay interest on the royalty due in excess of the royalty actually paid at the highest rate then permitted by law. In either event,
ACCENTIA will pay all of MAYO’s costs in conducting the audit. Failure by ACCENTIA to make any payment required under this Section 5.02 constitutes a material breach of this Agreement

otherwise, any logo, name, trade name, service mark, or trademark of MAYO or its Affiliates, including, but not limited to, the terms “Mayo®,” “Mayo Clinic®,” and the triple shield Mayo logo, or any simulation, abbreviation, or adaptation of the same, or the name of any MAYO employee or agent, without
MAYO’s prior, written, express consent. MAYO may withhold such consent in MAYO’s absolute discretion. Violation of this Section 6.01 constitutes a material breach of this Agreement. 
  
 6.02 Representations of MAYO. MAYO hereby represents and warrants that:

  

	(a)	MAYO either owns or licenses all of the Patent Rights and has the exclusive right to grant licenses and sublicenses therefore without the consent or approval of any third party;


  

	(b)	To the best of MAYO’s knowledge, all the Patent Rights are in full force and effect and have been maintained to date; 

  

	(c)	to the best of MAYO’s internal patent counsel’s knowledge, without the duty to inquire, MAYO is not aware of any written asserted or unasserted claim or demand against the
Patent Rights; 

  

	(d)	MAYO has not entered into any agreement with any third party which is in conflict with the rights granted to ACCENTIA pursuant to this Agreement. 

  
 6.03 No Warranties. Nothing in this Agreement will be construed as: 
  

	(a)	a warranty or representation by MAYO as to the validity or scope of any of the Patent Rights; or 

  

	(b)	an obligation to bring or to prosecute actions against third parties for infringement of the Patent Rights; or 

  

	(c)	a warranty or representation that the manufacture, use, sale, offer for sale or importation of any Product, or the use or practice of any of the Know-How or Patent Rights are free

Parties.

 (f) If a Material Change occurs, other than a Material Change under Section 1.16(c), MAYO may notify ACCENTIA in writing of such breach and
ACCENTIA will have thirty (30) days after such notice becomes effective as set forth in Section 10.05 to cure such breach to MAYO’s satisfaction. If ACCENTIA fails to cure such breach, MAYO may, at its option, terminate this Agreement in whole
or in part by sending ACCENTIA written notice of termination. 
  
 4.2 The
reference to “Section 1.17” in Section 7.03(b) of this Agreement shall be deleted and replaced with “Section 1.16.” 
  
 4.3 Section 1.17 is revised to insert “foreign counterparts of the foregoing including” before “European Application No. 98955065.2”. 
  
 4.4 Section 1.26 is revised to delete “with respect to FDA Products,” and to insert
at the end of the last sentence “for a Product or FDA Product”. 
  
 5.
The first sentence of Section 2.06 is replaced with: “Within a reasonable time after execution of this Agreement, MAYO shall make available to ACCENTIA the Know-How relating to chronic rhinosinusitis and within a reasonable time after execution
of this Amendment, Mayo will make Know-How relating to asthma available to ACCENTIA.” 
  
 5.1 Section 3.01(a) is replaced with: “In the Territory, an exclusive, sublicensable with MAYO’s written consent, royalty-bearing license under the Patent Rights to use, offer for sale, sell, develop,
manufacture and have manufactured, amphotericin-B and derivatives thereof as an FDA Product;” 
  
 6. The second to last paragraph in Section 3.01 is revised to include “and/or asthma” after “chronic rhinosinusitis” and includes “and its derivatives” after “amphotericin-B”.

  
 7. The “or” in the last line of Section 3.03(b) is replaced with
“of”. 
  
 7.1 The following sentence is added to Section 3.06 after
Subsection (d): “MAYO agrees that ACCENTIA plans to file a registration statement under the Securities Act of 1933 and that it is not prohibited or restricted by this Section 3.06 from making any disclosure of or regarding this Agreement

 8. The introduction to Section 4.01 is amended to change “[*] DOLLARS (US $[*])” to “[*] DOLLARS (US
$[*]).” Section 4.01 (c) is replaced with: 
  
 “[*] DOLLARS (US $[*])

November 11, 2004; and 
  
 (ii) [*] DOLLARS ($[*]) on or before
December 15, 2004.”

 (b) [*] on or before June 30, 2005; 
  
 (c) [*] on or before September 30, 2005; and 
  
 (d) [*] on or before December 31, 2005. 
  
 The Earned Royalties due and accrued under Section 4.02(b) and (c) within calendar year 2005 are fully creditable against minimum royalties due for said calendar year
2005. If the Earned Royalties do not equal or exceed the minimum royalty due, ACCENTIA will pay the difference by the time each such payment is due. Should the Minimum Royalties actually paid to Mayo in 2005, when such royalties are due, exceed the

Biopharmaceuticals, Inc. (the “Company”) and Accentia Specialty Pharmacy, Inc. First Amendment dated December 23, 2004 (as amended, the “License Agreement”), MAYO hereby subscribes for Two Million Four Hundred Thousand
(2,400,000) shares of Series E Convertible Preferred Stock of the Company (“Series E Preferred Shares”) pursuant to Rule 506 of Regulation D under the Securities Act of 1933, as amended. The Series E Preferred Shares shall be fully paid on
the date of issuance. 
  
 2. REPRESENTATIONS.

  
 2.1 Subscriber represents and warrants to the Company as follows: 

 
 (a) It is acquiring the Series E Preferred Shares for
investment and not with a view for resale or distribution of the shares; 
  
 (b) it agrees that the right to transfer the Series E Preferred Shares and the shares of Common Stock into which the shares of Series E Preferred Shares may be converted (the “Converted Shares”), is
restricted in accordance with state and federal securities laws; 
  
 (c) Subscriber is an “accredited investor” as defined in Regulation D promulgated under the Securities Act; 
  
 (d) The per-share purchase price of the shares of Series E Preferred Shares was established by negotiation between the Company and
Subscriber and Subscriber may experience substantial dilution to my investment; 
  
 (e) the Series E Preferred Shares and the Converted Shares are not publicly traded over any recognized exchange or at all, and there can
be no assurance that the Company’s securities will ever be publicly traded and that the Series E Preferred Shares being subscribed for hereunder are considered by Subscriber to be non-tradable and illiquid; 
  
 (f) The Company is subject to a high degree of risk; and

  
 (g) Subscriber did not use, and is not
obligated to pay any commission or other fee to, any finder or broker in connection with this transaction. 
  
 2.2 The Company represents and warrants to Subscriber as follows: 
  
 (a) The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Florida; 

 
 (b) The Company has all requisite corporate power and
authority to own and operate its properties and to carry on its business as presently conducted and as proposed to be conducted; 
  
 (c) The Company has all requisite legal and corporate power (i) to execute and deliver this Agreement and all listed exhibits hereto, (ii)
to issue the Series E 

  









 
Preferred Shares hereunder, (iii) to issue the Converted Shares at conversion of the Series E Preferred Shares, and (v) to carry out and perform its
obligations under the terms of this Agreement; 
  
 (d) The Company is duly qualified to transact business and is in good standing in each jurisdiction in which the failure to so qualify would have a material adverse effect on its business, operations, assets, liabilities, properties,
prospects, condition or affairs, financially or otherwise; 
  
 (e) The Series E Preferred Shares, when issued, sold and delivered in accordance with the terms hereof for the consideration expressed herein, will be duly and validly issued, fully paid, non assessable and free of
any liens or encumbrances and free of restrictions on transfer other than restrictions on transfer under this Agreement and applicable state and federal securities laws. Based in part upon the representations of Subscriber in this Agreement, the
Series E Preferred Shares and the Converted Shares will be issued in compliance with all applicable federal and state securities laws. The Converted Shares issued upon conversion of the Series E Preferred Shares will be duly and validly reserved for
issuance and, upon issuance in accordance with the terms of the Company’s Amended and Restated Articles of Incorporation, as amended to date (the “Articles”), shall be duly and validly issued, fully paid, non assessable and free of
restrictions on transfer other than restrictions on transfer under this Agreement and applicable state and federal securities laws, and issued in compliance with all applicable securities laws, as presently in effect, of the United States and each
of the states whose securities laws govern the issuance of any of the Series E Preferred Shares or the Converted Shares. The terms of the Series E Preferred Shares and Converted Shares as set forth in the Articles are legally binding obligations of
the Company and are enforceable in accordance with their terms. No documentary stamp tax, or similar tax, is or will be imposed on the Company’s issuance of the securities issued or issuable in connection with this Agreement or the transactions
contemplated hereunder under any state or local government or authority; 
  
 (g) The Company has delivered to Subscriber its unaudited consolidated financial statements for the fiscal years ending September 30, 2003 and September 30, 2004 (collectively, the “Financial Statements”).
The Financial Statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) applied on a consistent basis throughout the periods indicated, except that the Financial Statements may not contain all
footnotes required by GAAP. The Financial Statements fairly present in all material respects the financial condition and operating results of the Company as of the dates, and for the periods, indicated therein, subject to normal year-end audit
adjustments. Except as set forth in the Financial Statements, the Company has no material liabilities or obligations, contingent or otherwise, other than (i) liabilities incurred in the ordinary course of business subsequent to September 30, 2004
and (ii) obligations under contracts and commitments incurred in the ordinary course of business and not required under GAAP to be reflected in the Financial Statements, which, in both cases, individually and in the aggregate would not have a
material adverse effect. The Company maintains and will continue to maintain a standard system of accounting established and administered in accordance with GAAP; 
  
 (h) The Company has made available to Subscriber all the information reasonably available to the Company and

dispose of any Series E Preferred Shares or Converted Shares (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed one
