§§ 101 et seq. (the Bankruptcy Code), in the United States Bankruptcy Court for the Middle District of Florida, Tampa Division (the Bankruptcy Court), which case is currently being jointly
administered under Case No. 8:08-bk-17795-KRM (the Bankruptcy Case);

WHEREAS, as of
the Petition Date, Accentia was indebted to Laurus Master Fund, Ltd. (In Liquidation)(Laurus) in an aggregate amount of $15,020,896.08, according to a proof of claim filed by the Agent in the Bankruptcy Case (the Laurus
Prepetition Debt);

WHEREAS, as of the Petition Date, Accentia was indebted to Laurus in an
aggregate amount of $3,347,388.16 with respect to the 8% Secured Convertible Debentures Due September 29, 2010 issued by Accentia (the Accentia Debentures), according to a proof of claim filed by the Agent in the Bankruptcy

AGREEMENT

NOW, THEREFORE, in consideration of the mutual covenants and undertakings and the terms and conditions contained herein,
the parties hereto agree as follows:

1. General Definitions and Terms; Rules of Construction.

(a) General Definitions. Capitalized terms used in this Agreement shall have the meanings assigned to
them in Annex A.

(b) Accounting Terms. Any accounting terms used in this Agreement which are
not specifically defined herein shall have the meanings customarily given them in accordance with GAAP and all financial computations in this Agreement shall be computed, unless specifically provided herein, in accordance with GAAP consistently
applied.

(c) Other Terms. Any capitalized terms used in this Agreement and defined in the UCC shall
have the meaning given therein, unless otherwise defined herein.

(d) Rules of Construction. All
Schedules, Addenda, Annexes and Exhibits hereto or expressly identified to this Agreement are incorporated herein by reference and taken together with this Agreement constitute but a single agreement. The words herein, hereof
and hereunder or other words of similar import refer to this Agreement as a whole, including the Exhibits, Addenda, Annexes and Schedules thereto, as the same may be from time to time amended, modified, restated or supplemented in
accordance with the terms of this Agreement, and not to any particular section, subsection or clause contained in this Agreement. Wherever from the context it appears appropriate, each term stated in either the singular or the plural shall include
the singular and the plural, and pronouns stated in the masculine, feminine or neuter gender shall include the masculine, the feminine and the neuter. The term or is not exclusive. The term including (or any form thereof)
shall not be limiting or exclusive. All references to statutes and related regulations shall include any amendments of same and any successor statutes and regulations. All references in this Agreement or in the Schedules, Addenda, Annexes and
Exhibits to this Agreement to sections, schedules, disclosure schedules, exhibits, and attachments shall refer to the corresponding sections, schedules, disclosure schedules, exhibits, and attachments of or to this Agreement. All references to any
instruments or agreements, including references to this Agreement or any of the Ancillary Agreements, shall include any and all modifications or amendments thereto and any and all extensions or renewals thereof.

(e) This Agreement shall be subject to the terms and provisions of the Confirmed Plan. To the extent that there is any
conflict between the terms and provisions of this Agreement and the terms and provisions of the Confirmed Plan, the terms and provisions of this Agreement will control unless otherwise expressly stated in the Confirmation Order.

2. The Accentia Term Loans.

(a) Subject to the terms and conditions set forth herein and in the Ancillary Agreements, at the Closing, the Lenders will
receive in satisfaction of the Laurus Prepetition Debt, secured term promissory notes of Accentia in an aggregate principal amount of



2



---

$8,800,000.00 (the Accentia Term Notes). The Accentia Term Notes shall be issued to the Lenders in the principal amounts set forth on Schedule 2(a) attached hereto.

(b) If Accentia at any time fails to perform or observe any of the covenants contained in this Agreement or
in any Ancillary Agreement (after any applicable grace period and/or opportunity to cure), the Agent may upon written notice to Accentia, but need not, perform or observe such covenant on behalf and in the name, place and stead of Accentia (or, at
the Agents option, in the Agents name) and may, but need not, take any and all other actions which the Agent may deem necessary to cure or correct such failure (including the payment of Taxes, the satisfaction of Liens, the performance
of obligations owed to Account Debtors, lessors or other obligors, the procurement and maintenance of insurance, the execution of assignments, security agreements and financing statements, and the endorsement of instruments). The amount of all
monies expended and all out-of-pocket costs and reasonable expenses (including attorneys fees and legal expenses) incurred by the Agent in connection with or as a result of the performance or observance of such covenants or the taking of such
action by the Agent shall be charged to Accentia and added to the principal amount of the Accentia Term Notes. To facilitate the Agents performance or observance of such covenants by Accentia, Accentia hereby irrevocably appoints the Agent, or
the Agents delegate, acting alone, as Accentias attorney in fact (which appointment is coupled with an interest) with the right (but not the duty) from time to time to create, prepare, complete, execute, deliver, endorse or file in the
name and on behalf of Accentia any and all instruments, documents, assignments, security agreements, financing statements, applications for insurance and other agreements and writings required to be obtained, executed, delivered or endorsed by
Accentia.

(c) The Agent will account to Accentia monthly with a statement of all advances, charges and
payments made pursuant to this Agreement, and such account rendered by the Agent shall be deemed final, binding and conclusive, absent manifest error, unless the Agent is notified by Accentia in writing to the contrary within thirty (30) days
of the date such account was rendered specifying the item or items to which objection is made.

3.
Repayment of the Accentia Term Loans. The Accentia Term Loans shall be repaid in accordance with the terms of the Accentia Term Notes and as set forth herein. Accentia may prepay the Accentia Term Loans from time to time in accordance with
the terms and provisions of the Accentia Term Notes.

4. Reserved.

5. Interest and Payments.

(a) Interest.

(i) Accentia shall pay interest on the
Accentia Term Loans at the rates per annum set forth in the Accentia Term Notes.

(ii) In no event shall the
aggregate interest payable hereunder or under the Accentia Term Notes exceed the maximum rate permitted under any applicable law or regulation, as in effect from time to time (the Maximum Legal Rate), and if any provision of this
Agreement or any Ancillary Agreement is in contravention of any such law or regulation,



3



---

interest payable under this Agreement and each Ancillary Agreement shall be computed on the basis of the Maximum Legal Rate (so that such interest will not exceed the Maximum Legal Rate).

(iii) Accentia shall pay principal, interest and all other amounts payable hereunder, or under any Ancillary
Agreement, without any deduction whatsoever, including any deduction for any set-off or counterclaim.

(iv)
All Contract Rate payments made by Accentia under the Accentia Term Notes shall be made free and clear of, and without deduction or withholding for or on account of, any future Taxes hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, other than Excluded Taxes. If any Non-Excluded Taxes or Other Taxes are required to be withheld from any amounts payable to any Creditor Party hereunder, the amounts so payable to such Creditor Party shall be increased to the
extent necessary to yield to such Creditor Party (after payment of all Non-Excluded Taxes and Other Taxes, including those imposed on payments made pursuant to this paragraph (iv) of this Section 5(a)) interest or any such other amounts
payable hereunder at the rates or in the amounts specified in this Agreement, provided, however, that Accentia shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes that are
directly attributable to such Lenders failure to comply with the requirements of paragraph (vii) of this Section 5(a); and provided, further, however, that if Accentia is required to increase the amounts payable
to any Creditor Party by reason of this Section 5(a)(iv), Accentia shall pay such increased amounts within ninety (90) days following the date on which such Non-Excluded Taxes or Other Taxes were withheld.

(v) In addition, subject to 11 U.S.C. §1146(a) and the terms of the Confirmation Order, Accentia shall pay any
Other Taxes to the relevant Governmental Authority in accordance with applicable law.

(vi) Whenever any
Non-Excluded Taxes or Other Taxes are payable by Accentia, as promptly as possible thereafter Accentia shall send to the Agent for its own account or for the account of the relevant Lender, as the case may be, a certified copy of an original
official receipt received by Accentia showing payment thereof (or such other evidence reasonably satisfactory to the Agent). If Accentia fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to
remit to the Agent the required receipts or other required documentary evidence, Accentia shall indemnify the Creditor Parties for any incremental taxes, interest or penalties that may become payable by any Creditor Party as a result of any such
failure.

(vii) Each Lender (or its assignee) that is not a United States person, as defined in
Section 7701(a)(30) of the Code (a Non-U.S. Lender) shall, and hereby agrees to, deliver to Accentia and the Agent two completed originals of an appropriate U.S. Internal Revenue Service Form W-8, as applicable, or any
subsequent versions thereof or successors thereto, properly completed and duly executed by such Non-U.S. Lender. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to this Agreement. In addition, each
Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender



4



---

shall promptly notify Accentia at any time it determines that it is no longer in a position to provide any previously delivered certificate to Accentia (or any other form of certification adopted
by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not legally able to deliver.

(viii) The agreements in this Section 5(a) shall survive the termination of this Agreement and the
payment of the Accentia Term Loans and all other amounts payable hereunder or under any other Ancillary Agreement.

(b) Failure to Provide Financial Information. Without affecting the Lenders rights and remedies, in the event Accentia fails to deliver the financial information required by Section 11
on or before the dates set forth therein, Accentia shall pay each Lender its pro rata share of an aggregate fee in the amount of $250.00 per week (or portion thereof) for each such failure until the missing financial information is delivered to the
Agent. All amounts incurred pursuant to this Section 5(b) shall be due and payable upon receipt by Accentia of an invoice from the Agent for such amounts, which shall be paid monthly, in arrears, on the first Business Day of each calendar
month.

6. Security Interest.

(a) Subject only to the Permitted Liens, to secure the prompt payment to the Creditor Parties of the Obligations, Accentia
hereby assigns, pledges and grants to the Agent, for the ratable benefit of the Creditor Parties, a continuing security interest in and Lien upon all of the Collateral. All of Accentias Books and Records relating to the Collateral shall, until
delivered to or removed by the Agent, be kept by Accentia in trust for the Creditor Parties until the termination of this Agreement and the payment in full of all Obligations. Each confirmatory assignment schedule or other form of assignment
hereafter executed by Accentia shall be deemed to include the foregoing grant, whether or not the same appears therein.

(b) Accentia hereby (i) authorizes the Agent to file any financing statements, continuation statements or other amendments thereto that (A) indicate the Collateral (1) as all assets and
personal property of Accentia or words of similar effect, regardless of whether any particular asset comprised in the Collateral falls within the scope of Article 9 of the UCC of the applicable jurisdiction, or (2) as being of an equal or
lesser scope or with greater detail, and (B) contain any other information required by Part 5of Article 9 of the UCC for the sufficiency or filing office acceptance of any financing statement, continuation statement or other amendment
and (ii) ratifies its authorization for the Agent to have filed any initial financial statements, or amendments thereto if filed prior to the date hereof. Except as otherwise provided in the Confirmed Plan, Accentia acknowledges that it is not
authorized to file and, except as expressly set forth in this Agreement, will not give any authorization to anyone other than the Agent (including pursuant to Section 9-509(b) of the UCC) to file, any financing statement or amendment or
termination statement with respect to any financing statement without the prior written consent of the Agent and agrees that it will not do so without the prior written consent of the Agent, subject to Accentias rights under
Section 9-509(d)(2) of the UCC.



5



---

(c) Subject to the Liens in favor of the holders of the 8.50% Secured
Convertible Debentures Due November 17, 2013 issued by Accentia on November 17, 2010, Accentia hereby grants to the Agent, for the ratable benefit of the Creditor Parties, an irrevocable, non-exclusive, worldwide license without payment of
royalty or other compensation to Accentia, upon the occurrence and during the continuance of an Event of Default, to use or otherwise exploit in any manner as to which authorization of the holder of such Intellectual Property would be required, and
to license or sublicense such rights in, to and under any Intellectual Property now or hereafter owned by or licensed to Accentia, and wherever the same may be located, and including in such license access to all media in which any of such
Intellectual Property may be recorded or stored and to all software and hardware used for the compilation or printout thereof. Subject to the Liens in favor of the holders of the 8.50% Secured Convertible Debentures Due November 17, 2013 issued
by Accentia on November 17, 2010, Accentia represents, promises and agrees that any such license or sublicense is not and will not be in conflict with the contractual or commercial rights of any third Person and subject, in the case of
trademarks and service marks, to sufficient rights to quality control and inspection in favor of Accentia to avoid the right of invalidation of said trademarks and service marks. The foregoing license and sublicense will terminate on the termination
of this Agreement and the payment in full of the Obligations; provided, however, that any license, sublicense, or other rights granted by the Agent pursuant to such license during its term in connection with any enforcement of remedies
by Agent hereunder shall remain in effect in accordance with its terms.

(d) Any proceeds received by the
Agent from the foreclosure, sale, lease or other disposition of any of the Collateral shall be paid over to the Lenders for application in accordance with Section 21.

(e) Notwithstanding anything to the contrary contained in this Agreement or in any Ancillary Agreement, the shares of
Biovest Common Stock pledged as collateral for Accentias obligations to Southwest Bank or its assignee and McKesson Corporation, who hold 15,000,000 and 18,000,000 shares, respectively (the Biovest Pledged Shares), shall not
constitute Collateral for purposes of this Agreement, including if and when any of the Biovest Pledged Shares are released by either of Southwest Bank or its assignee or McKesson Corporation. In the event that Accentia, subsequent to any
such release, pledges the Biovest Pledged Shares as collateral to a third party pursuant to any loan or other financing, and such loan or financing is in excess of the obligations presently owed to Southwest Bank or its assignee and McKesson
Corporation in an aggregate amount of $8,825,051.00 (the Accentia Loan Obligations), Accentia shall prepay the Accentia Term Notes in an amount equal to thirty (30%) of the net proceeds received by Accentia from any such loan
or financing, but such 30% prepayment shall only apply to such amount of any loan or financing that is in excess of the Accentia Loan Obligations. In addition, in the event that, subsequent to any such release, Accentia sells any of the Biovest
Pledged Shares to a third party, Accentia shall prepay the Accentia Term Notes in an amount equal to thirty percent (30%) of the net proceeds received by Accentia from any such sale.

7. Representations, Warranties and Covenants Concerning the Collateral. Accentia represents, warrants and
covenants as of the date hereof as follows:



6



---

(a) All of the Collateral (i) is owned by it free and clear of all
Liens (including any claim of infringement) except those in the Agents favor and Permitted Liens and (ii) is not subject to any agreement prohibiting the granting of a Lien or requiring notice of or consent to the granting of a Lien.

(b) It shall not encumber, mortgage, pledge, assign or grant any security interest in or Lien upon any
Collateral to anyone other than the Agent and the other Creditor Parties and except for Permitted Liens.

(c)
The Liens granted pursuant to this Agreement, upon the filing of UCC-1 financing statements in respect of Accentia in favor of the Agent in the applicable filing office of the state of organization of Accentia, the recording of the Liens in favor of
the Agent in the U.S. Patent and Trademark Office and the U.S. Copyright Office, as applicable, the taking of any actions required under the laws of jurisdictions outside the United States with respect to Intellectual Property included in the
Collateral which is created under such laws, and the completion of the other filings and actions listed on Schedule 7(c) attached hereto, constitute valid perfected security interests in all of the Collateral in favor of the Agent as security
for the payment of the Obligations, enforceable in accordance with the terms hereof against any and all of Accentias creditors and purchasers and such security interests are prior to all other Liens in existence on the date hereof except those
relating to the Permitted Liens, which, pursuant to the Confirmed Plan, are senior in priority to the Liens granted in favor of the Agent under this Agreement.

(d) No effective security agreement, mortgage, deed of trust, financing statement, equivalent security or Lien instrument or continuation statement covering all or any part of the Collateral is on file or
of record in any public office, except those relating to Permitted Liens.

carry out their provisions. All corporate action on such Lenders part required for the lawful execution and delivery of this Agreement and the Ancillary Agreements has been or will be effectively taken prior to the Closing Date. Upon their
execution and delivery, this Agreement and the Ancillary Agreements shall be valid and binding



21



---

obligations of such Lender, enforceable in accordance with their terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general
application affecting enforcement of creditors rights, and (ii) as limited by general principles of equity that restrict the availability of equitable and legal remedies.

(b) Investment Representations. Such Lender understands that the Accentia Term Notes are being offered and sold
pursuant to an exemption from registration contained in Section 1145(a) of the Bankruptcy Code and the Securities Act based in part upon such Lenders representations contained in this Agreement, including, without limitation, that such
Lender is an accredited investor within the meaning of Regulation D under the Securities Act. Such Lender has received or has had full access to all the information it considers necessary or appropriate to make an informed investment
decision with respect to the Accentia Term Notes to be issued to it under this Agreement.

(c) Lender Bears
Economic Risk. Such Lender has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to Accentia so that it is capable of evaluating the merits and risks of its investment in
Accentia and has the capacity to protect its own interests. Such Lender must bear the economic risk of this investment until the Accentia Term Notes are sold pursuant to (i) an effective registration statement under the Securities Act, or
(ii) an exemption from registration is available.

(d) Investment for Own Account. The Accentia
Term Notes are being issued to such Lender for its own account for investment only, and not as a nominee or agent and not with a view towards or for resale in connection with their distribution.

(e) Lender Can Protect Its Interest. Such Lender represents that by reason of its, or of its managements,
business and financial experience, such Lender has the capacity to evaluate the merits and risks of its investment in the Accentia Term Notes and to protect its own interests in connection with the transactions contemplated in this Agreement and the
Ancillary Agreements. Further, such Lender is aware of no publication of any advertisement in connection with the transactions contemplated in this Agreement or the Ancillary Agreements.

(f) Accredited Investor. Such Lender represents that it is an accredited investor within the meaning of Regulation
D under the Securities Act.

(g) Patriot Act. Such Lender certifies that, to the best of such
Lenders knowledge, such Lender has not been designated, and is not owned or controlled, by a suspected terrorist as defined in Executive Order 13224. Such Lender seeks to comply with all applicable laws concerning money laundering
and related activities. In furtherance of those efforts, such Lender hereby represents, warrants and covenants that: (i) none of the cash or property that such Lender will use to make the Accentia Term Loans has been or shall be derived from,
or related to, any activity that is deemed criminal under United States law; and (ii) no disbursement by such Lender to Accentia, to the extent within such Lenders control, shall cause such Lender to be in violation of the United States
Bank Secrecy Act, the United States International Money Laundering Control Act of 1986 or the United States International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001. Such Lender shall promptly notify Accentia if any of these
representations ceases to be true and accurate regarding such



22



---

Lender. Such Lender agrees to provide Accentia any additional information regarding such Lender that Accentia deems necessary or convenient to ensure compliance with all applicable law concerning
money laundering and similar activities. Such Lender understands and agrees that if at any time it is discovered that any of the foregoing representations are incorrect, or if otherwise required by applicable law or regulation related to money
laundering or similar activities, such Lender may undertake appropriate actions to ensure compliance with applicable law or regulation, including but not limited to segregation and/or redemption of such Lenders investment in Accentia. Such
Lender further understands that Accentia may release information about such Lender and, if applicable, any underlying beneficial owners, to proper authorities if Accentia, in its sole discretion, determines that it is in the best interests of
Accentia in light of relevant rules and regulations under the laws set forth in subsection (ii) above.

(h) Limitation on Acquisition of Stock. Notwithstanding anything to the contrary contained in this Agreement, any
Ancillary Agreement, or any document, instrument or agreement entered into in connection with any other transaction entered into by and between such Lender and Accentia (and/or Subsidiaries or Affiliates of Accentia), such Lender (and/or
Subsidiaries or Affiliates of such Lender) shall not acquire stock in Accentia (including, without limitation, pursuant to a contract to purchase, by exercising an option or warrant, by converting any other security or instrument, by acquiring or
exercising any other right to acquire shares of stock or other security convertible into shares of stock in Accentia, or otherwise, and such options, warrants, conversion or other rights shall not be exercisable) to the extent such stock acquisition
would cause any interest (including any original issue discount) payable by Accentia to a Non-U.S. Lender not to qualify as portfolio interest, within the meaning of Section 871(h)(2) or Section 881(c)(2) of the U.S. Internal Revenue Code
of 1986, as amended (the Code) by reason of Section 87l(h)(3) or Section 88l(c)(3)(B) of the Code, as applicable, taking into account the constructive ownership rules under Section 871(h)(3)(C) of the Code (the
Stock Acquisition Limitation).

(i) Reserved.

(j) Ancillary Agreements and Other Closing Documents. The Agent and the Lenders acknowledge and agree that, as a
condition to the Closing, the closing under the Biovest Security Agreement shall have occurred and the Agent and the Lenders, as the case may be, shall have executed and delivered each of the Ancillary Agreements and other documents listed in
Section 14(c).

(k) Reserved.

17. Confidentiality. Except in connection with the Bankruptcy Case, each Lender covenants and agrees with Accentia
that such Lender will not disclose, and will not include in any public announcement, the name of Accentia, unless expressly agreed to by Accentia or unless and until such disclosure is required by law or applicable regulation, and then only to the
extent of such requirement. Notwithstanding the foregoing, (i) such Lender shall be permitted to discuss, distribute or otherwise transfer any non-public information of Accentia in such Lenders possession now or in the future to
(x) its employees, agents, counsel, professional consultants and accountants who, in each such case, have a specific need to know such information, and (y) potential or actual (A) direct or indirect investors in such Lender and
(B) assignees or transferees



23



---

of all or a portion of the Obligations, to the extent that such investor or assignee or transferee enters into a confidentiality agreement for such benefit of Accentia in such form as may be
necessary to address Accentias Regulation FD requirements; (ii) such Lender (and each employee, representative, or other agent of such Lender) may disclose to any and all Persons, without limitation of any kind, the tax treatment and any
facts that may be relevant to the tax structure of the transactions contemplated by this Agreement and the Ancillary Agreements and the agreements referred to therein; provided, however, that no Lender (and no employee, representative or
other agent thereof) shall disclose pursuant to this clause (ii) any other information that is not relevant to understanding the tax treatment or tax structure of such transactions (including the identity of any party or any information that
could lead another to determine the identity of any party); and (iii) the Agent or any Affiliate thereof shall be entitled to post on its website a summary of the transactions contemplated by this Agreement, including Accentias name.

18. Power of Attorney. Accentia hereby appoints the Agent, or any other Person whom the Agent may
designate as Accentias attorney, with power to: (a)(i) execute any security related documentation on such Accentias behalf and to supply any omitted information and correct patent errors in any documents executed by Accentia or on
Accentias behalf; (ii) file financing statements and other evidence of Liens granted hereunder against Accentia covering the Collateral (and, in connection with the filing of any such financing statements, describe the Collateral as
all assets and all personal property, whether now owned and/or hereafter acquired (or any substantially similar variation thereof)); (iii) sign Accentias name on any invoice or bill of lading relating to any Accounts, drafts
against Account Debtors, schedules and assignments of Accounts, notices of assignment, financing statements and other evidence of the Agents Liens granted hereunder and other public records, verifications of Account and notices to or from
Account Debtors; (iv) in the case of any Intellectual Property, execute and deliver, and have recorded, any and all agreements, instruments, documents and papers as the Agent may request to evidence the Agents security interest in such
Intellectual Property and the goodwill and general intangibles of Accentia relating thereto or represented thereby; and (v) do all other things the Agent deems necessary to carry out the terms of Section 6 of this Agreement; and
(b) upon the occurrence and during the continuance of an Event of Default (i) endorse Accentias name on any checks, notes, acceptances, money orders, drafts or other forms of payment or security that may come into the Agents
possession; (ii) verify the validity, amount or any other matter relating to any Account by mail, telephone, telegraph or otherwise with Account Debtors; (iii) do all other things necessary to carry out this Agreement, any Ancillary
Agreement and all related documents; and (iv) notify the post office authorities to change the address for delivery of Accentias mail to an address designated by the Agent, and to receive, open and dispose of all mail addressed to
Accentia. Accentia hereby ratifies and approves all acts of the attorney. Neither the Agent nor the attorney will be liable for any acts or omissions or for any error of judgment or mistake of fact or law, except for gross negligence or willful
misconduct. This power, being coupled with an interest, is irrevocable so long as the Agent has a security interest and until the Obligations have been fully satisfied.

19. Termination of Lien. The Liens and rights granted to the Agent hereunder and in any Ancillary Agreements, and
the financing statements filed in connection herewith or therewith, shall continue in full force and effect until all of the Obligations have been indefeasibly paid or performed in full. The Agent shall not be required to send termination



24



---

statements or other evidence of the release of the Liens granted hereunder to Accentia, or to file them with any filing office, unless and until this Agreement and the Ancillary Agreements shall
have been terminated in accordance with their terms and all Obligations indefeasibly paid in full in immediately available funds.

20. Events of Default. The occurrence of any of the following shall constitute an Event of Default:

(a) failure to make payment of any principal, interest, fees, costs, charges, expenses, or other sums payable from time
to time hereunder, under the Accentia Term Notes, under Section 5(b) of this Agreement, if any, or under any of the Ancillary Agreements when required hereunder or thereunder, and, in any such case, such failure shall continue for (i) in
the case of a payment of scheduled principal or interest, a period of five (5) Business Days following the date upon which any such payment was due, (ii) in the case of payments due under Section 5(b), if any, that are not paid when
due on eight (8) occasions, or (iii) in the case of any other amount payable, a period of five (5) Business Days following the date of Accentias written receipt from the Agent of a written notice identifying the amount due and
providing reasonable supporting details;

consent to or suffer to exist the appointment of or the taking of possession by, a receiver, custodian, trustee or liquidator of itself or of all or a substantial part of its property, (ii) make a general assignment for the benefit of

cease operation of its present business; or

(d) Accentia directly or indirectly sells, assigns, transfers,

21. Remedies. Following the occurrence of an Event of Default that is continuing, the Agent shall have the right to demand repayment in full of all Obligations, whether or not otherwise due. Until
all Obligations have been fully and indefeasibly satisfied, the Agent shall retain its Lien in all Collateral. The Agent shall have, in addition to all other rights provided herein and in each Ancillary Agreement, the rights and remedies of a
secured party under the UCC, and under other applicable law, all other legal and equitable rights to which the Agent may be entitled, including the right to take immediate possession of the Collateral, to require Accentia to assemble the Collateral,
at Accentias expense, and to make it available to the Agent at a place designated by the Agent which is reasonably convenient to both parties and to enter any of the premises of Accentia or wherever the Collateral shall be located, with or
without force or process of law, and to keep and store the same on said premises until sold (and if said premises be the property of Accentia, Accentia agrees not to charge the Agent or any Lender for storage thereof),



25



---

and the right to apply for the appointment of a receiver for Accentias property. Further, the Agent may, at any time or times after the occurrence of an Event of Default that is continuing,
sell and deliver all Collateral held by or for the Agent at public or private sale for cash, upon credit or otherwise, at such prices and upon such terms as the Agent, in its sole discretion, deems advisable or the Agent may otherwise recover upon
the Collateral in any commercially reasonable manner. The requirement of reasonable notice shall be met if such notice is mailed postage prepaid to Accentia at Accentias address as shown in Section 30, at least ten (10) days before
the time of the event of which notice is being given. The Agent may be the purchaser at any sale, if it is public. In connection with the exercise of the foregoing remedies, and not without limitations of any remedies with respect to Intellectual
Property Collateral, the Agent may exercise the rights and license granted under Section 6(c) hereof. The proceeds of sale shall be applied first to all costs and expenses of sale, including reasonable attorneys fees, and second to the
payment (in whatever order the Agent elects) of all Obligations. After the indefeasible payment and satisfaction in full of all of the Obligations, and after the payment by the Agent of any other amount required by any provision of law, including
Section 9-608(a)(1) of the UCC (but only after the Agent has received what the Agent considers reasonable proof of a subordinate partys security interest), the surplus, if any, shall be paid to Accentia or its representatives or to
whosoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. Accentia shall remain liable to the Creditor Parties for any deficiency. The parties hereto each hereby agree that the exercise by any party
hereto of any right granted to it or the exercise by any party hereto of any remedy available to it (including, without limitation, the issuance of a notice of redemption, a borrowing request and/or a notice of default), in each case, hereunder or
under any Ancillary Agreement shall not constitute confidential information and no party shall have any duty to the other party to maintain such information as confidential, except for the portions of such publicly filed documents that are subject
to a confidential treatment request made by Accentia to the SEC.

22. Waivers. To the full extent
permitted by applicable law, Accentia hereby waives (a) presentment, demand and protest, and notice of presentment, dishonor, intent to accelerate, acceleration, protest, default, nonpayment, maturity, release, compromise, settlement, extension
or renewal of any or all of this Agreement and the Ancillary Agreements or any other notes, commercial paper, Accounts, contracts, Documents, Instruments, Chattel Paper and guaranties at any time held by the Agent on which Accentia may in any way be
liable, and hereby ratifies and confirms whatever the Agent may do in this regard; (b) all rights to notice and a hearing prior to the Agents taking possession or control of, or to the Agents replevy, attachment or levy upon, any
Collateral or any bond or security that might be required by any court prior to allowing the Agent to exercise any of its remedies; and (c) the benefit of all valuation, appraisal and exemption laws. Accentia acknowledges that it has been
advised by counsel of its choices and decisions with respect to this Agreement, the Ancillary Agreements and the transactions evidenced hereby and thereby.

23. Expenses. Accentia shall pay all of the Agents out-of-pocket costs and expenses, including reasonable fees and disbursements of outside counsel and appraisers, in connection with the
prosecution or defense of any action, contest, dispute, suit or proceeding concerning any matter in any way arising out of, related to or connected with this Agreement or any Ancillary Agreement. Accentia shall also pay all of the Agents
reasonable fees, charges, out-of-pocket costs and expenses, including fees and disbursements of counsel and appraisers, in connection



26



---

with (a) the preparation, execution and delivery of any waiver, any amendment thereto or consent proposed or executed in connection with the transactions contemplated by this Agreement or
the Ancillary Agreements, (b) the Agents obtaining performance of the Obligations under this Agreement and any Ancillary Agreements, including, but not limited to, the enforcement or defense of the Agents security interests,
assignments of rights and Liens hereunder as valid perfected security interests, (c) any attempt to inspect, verify, protect, collect, sell, liquidate or otherwise dispose of any Collateral, (d) any appraisals or re-appraisals of any
property (real or personal) pledged to the Agent by Accentia as Collateral for, or any other Person as security for, the Obligations hereunder, and (e) any consultations in connection with any of the foregoing. Accentia shall also pay each
Creditor Party the customary bank charges for any bank services (including wire transfers) performed or caused to be performed by it for Accentia at Accentias request or in connection with Accentias loan account with such Creditor Party.
All such costs and expenses together with all filing, recording and search fees, taxes and interest payable by Accentia to the Creditor Parties shall be payable on demand and shall be secured by the Collateral. If any tax by any Governmental
Authority is or may be imposed on or as a result of any transaction between Accentia, on the one hand, and any Creditor Party on the other hand, which such Creditor Party is or may be required to withhold or pay, Accentia shall hereby indemnify and
hold such Creditor Party harmless in respect of such taxes, and Accentia will repay to such Creditor Party the amount of any such taxes which shall be charged to Accentias account; and until Accentia shall furnish such Creditor Party with
indemnity therefor (or supply such Creditor Party with evidence satisfactory to it that due provision for the payment thereof has been made), such Creditor Party may hold without interest any balance standing to Accentias credit and the Agent
shall retain its Liens in any and all Collateral.

24. Assignment; Register.

(a) Each Lender may assign any or all of the Obligations to any Person and, subject to acceptance and recordation thereof
by the Agent pursuant to Section 24(b) and receipt by the Agent of a copy of the agreement or instrument pursuant to which such assignment is made (each such agreement or instrument, an Assignment Agreement), any such
assignee shall succeed to all of such Lenders rights with respect thereto; provided that no Lender shall be permitted to effect any such assignment to a direct competitor of Accentia unless an Event of Default has occurred and is continuing
and such Lender has given Accentia no less than fifteen (15) Business Days prior notice of such assignment. Each Lender may from time to time sell or otherwise grant participations in any of the Obligations and the holder of any such
participation shall, subject to the terms of any agreement between such Lender and such holder, be entitled to the same benefits as such Lender with respect to any security for the Obligations in which such holder is a participant. Accentia agrees
that each such holder may exercise any and all rights of bankers lien, set-off and counterclaim with respect to its participation in the Obligations as fully as though Accentia were directly indebted to such holder in the amount of such
participation. Accentia may not assign any of its rights or obligations hereunder without the prior written consent of the Agent. All of the terms, conditions, promises, covenants, provisions and warranties of this Agreement shall inure to the
benefit of each of the undersigned, and shall bind the representatives, successors and permitted assigns of Accentia and the Creditor Parties.

(b) The Agent shall maintain, or cause to be maintained, for this purpose only as agent for each Lender, (i) a copy of each Assignment Agreement delivered to it and (ii) a book



27



---

entry system, within the meaning of U.S. Treasury Regulation Sections 5f.103-1(c) and 1.871-14(c) (the Register), in which it will register the name and address of each Lender
and the name and address of each assignee of each Lender under this Agreement, and the principal amount of, and stated interest on, the Accentia Term Loans owing to each such Lender and assignee pursuant to the terms hereof and each Assignment
Agreement. The right, title and interest of the Lenders and their assignees in and to such Accentia Term Loans shall be transferable only upon notation of such transfer in the Register, and no assignment thereof shall be effective until recorded
therein. Accentia and each Creditor Party shall treat each Person whose name is recorded in the Register as a Lender pursuant to the terms hereof as a Lender and owner of an interest in the Obligations hereunder for all purposes of this Agreement,
notwithstanding notice to the contrary or any notation of ownership or other writing or any Accentia Term Note. The Register shall be available for inspection by Accentia or Lender, at any reasonable time and from time to time, upon reasonable prior
notice.

25. No Waiver; Cumulative Remedies. Failure by any Creditor Party to exercise any right,
remedy or option under this Agreement, any Ancillary Agreement or any supplement hereto or thereto or any other agreement between or among Accentia and such Creditor Party, will not operate as a waiver; no waiver by any Creditor Party will be
effective unless it is in writing and then only to the extent specifically stated. The Creditor Parties rights and remedies under this Agreement and the Ancillary Agreements will be cumulative and not exclusive of any other right or remedy
which any of the Creditor Parties may have.

26. Application of Payments. Except as otherwise provided
in this Agreement or in any Ancillary Agreement, Accentia irrevocably waives the right to direct the application of any and all payments at any time or times hereafter received by the Agent from or on Accentias behalf and Accentia hereby
irrevocably agrees that the Agent shall have the continuing exclusive right to apply and reapply any and all payments received at any time or times hereafter against the Obligations hereunder in such manner as the Agent may reasonably deem advisable
notwithstanding any entry by the Agent upon any of the Agents books and records.

27. Indemnity.
Accentia hereby indemnifies and holds each Creditor Party, and its respective affiliates, employees, attorneys and agents (each, an Indemnified Person), harmless from and against any and all suits, actions, proceedings, claims,
damages, losses, liabilities and expenses of any kind or nature whatsoever (including reasonable attorneys fees and disbursements and other costs of investigation or defense, including those incurred upon any appeal) which may be instituted or
asserted against or incurred by any such Indemnified Person as the result of credit having been extended, suspended or terminated under this Agreement or any of the Ancillary Agreements or with respect to the execution, delivery, enforcement,
performance and administration of, or in any other way arising out of or relating to, this Agreement, the Ancillary Agreements or any other documents or transactions contemplated by or referred to herein or therein and any actions or failures to act
with respect to any of the foregoing, except to the extent that any such indemnified liability is finally determined by a court of competent jurisdiction to have resulted primarily from such Indemnified Persons gross negligence, bad faith or
willful misconduct. NO INDEMNIFIED PERSON SHALL BE RESPONSIBLE OR LIABLE TO ACCENTIA OR TO ANY OTHER PARTY OR TO ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY BENEFICIARY OR ANY OTHER PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT,



28



---

PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED, SUSPENDED OR TERMINATED UNDER THIS AGREEMENT OR ANY ANCILLARY AGREEMENT OR AS A

---

(b) ACCENTIA HEREBY CONSENTS AND AGREES THAT THE STATE AND/OR FEDERAL COURTS
LOCATED IN THE COUNTY OF NEW YORK, STATE OF NEW YORK SHALL HAVE EXCLUSIVE JURISDICTION TO HEAR AND DETERMINE ANY CLAIMS OR DISPUTES BETWEEN ACCENTIA, ON THE ONE HAND, AND ANY CREDITOR PARTY, ON THE OTHER HAND, PERTAINING TO THIS AGREEMENT OR ANY OF
THE ANCILLARY AGREEMENTS OR TO ANY MATTER ARISING OUT OF OR RELATED TO THIS AGREEMENT OR ANY OF THE ANCILLARY AGREEMENTS; PROVIDED, THAT EACH CREDITOR PARTY AND ACCENTIA ACKNOWLEDGES THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY
A COURT LOCATED OUTSIDE OF THE COUNTY OF NEW YORK, STATE OF NEW YORK; AND FURTHER PROVIDED, THAT NOTHING IN THIS AGREEMENT SHALL BE DEEMED OR OPERATE TO PRECLUDE ANY CREDITOR PARTY FROM BRINGING SUIT OR TAKING OTHER LEGAL ACTION IN ANY OTHER
JURISDICTION TO COLLECT THE OBLIGATIONS, TO REALIZE ON THE COLLATERAL OR ANY OTHER SECURITY FOR THE OBLIGATIONS, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF ANY CREDITOR PARTY. ACCENTIA EXPRESSLY SUBMITS AND CONSENTS IN ADVANCE TO SUCH

refunded to Accentia.

34. Severability. Wherever possible, each provision of this Agreement or the
Ancillary Agreements shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement or the Ancillary Agreements shall be prohibited by or invalid under applicable law such provision

true and correct when made. All statements as to factual matters contained in any certificate or other instrument delivered by or on behalf of Accentia pursuant hereto in connection with the transactions contemplated hereby shall be deemed to be
representations and warranties by Accentia hereunder solely as of the date of such certificate or instrument. All indemnities set forth herein shall survive the execution, delivery and termination of this Agreement and the Ancillary Agreements and
