Development Plan is submitted with respect to such indication and Accentia materially deviates from or abandons, fails to continuously pursue or fails to use reasonable efforts to meet any of the milestones in a New Development Plan, such indication
shall be removed from the definitions of Exclusive Clinical Field and Clinical Field and shall no longer be subject to this Agreement. Any amendment or material modification to the New Development Plan must comply with the

and no longer be subject to this Agreement if Accentia does not produce a New Development Plan within such period.

New Development Plan delivered pursuant to this subsection (ii), such indication shall be removed from the definitions of Exclusive Clinical Field and Clinical Field and shall no longer be subject to this Agreement.

2.3 Restriction of Sales/Use. Accentia shall not sell or re-sell, offer for sale or re-sale, promote, market, transfer,
distribute or otherwise engage in the disposition of, whether on its own or via a Third Party, the Product as purchased from Baxter without relabeling the Product as Accentia Product. Accentia shall comply with all applicable law and regulations in
its use and handling of the Product, and shall not use the Product in any unapproved or unlawful manner (other than in connection with clinical trial(s) for indications under the Clinical Field). Accentia shall be responsible for labeling the
Product for pre-clinical and/or clinical use.

2.4 Relationship of the Parties. Accentia shall not represent itself as
an agent of Baxter for any purpose nor pledge Baxters credit or give any condition or warranty or make any representation on Baxters behalf or commit Baxter to any contracts. Further, Accentia shall not without Baxters prior
written consent make any promises or guarantees with reference to the Product beyond those contained in the promotional material supplied or approved by Baxter or otherwise incur any liability on behalf of Baxter. Notwithstanding the foregoing, upon
the prior written consent of Baxter, which consent shall not be unreasonable withheld or delayed, Accentia may use descriptions or claims for re-labeled Accentia Product which are commercially reasonable under the applicable marketing approval
granted by the FDA (or other governmental authority of similar scope and authority) for such re-labeled Accentia Product. With respect to commercial use only (and specifically not for clinical use), Baxter will reasonably cooperate, at
Accentias expense, with requests by Accentia for descriptions, claims, labels and/or package inserts with regard to the Product that are commercially reasonable and directed by the applicable marketing approval for indications under the

of each year thereafter, Accentia will provide to Baxter in writing an annual forecast for each calendar year during the remainder of the term of Accentias estimated requirements for each Product (the Long Range Forecast).
Commencing on the Commencement Date for Annual Forecasts of this Agreement and prior to the tenth (10th) calendar day of each month thereafter, Accentia will provide Baxter in writing a twelve (12) month rolling forecast of Accentias estimated requirements for each Product (the
Rolling Forecast); other than the first ninety (90) days of each Rolling Forecast, which shall be binding, Baxter specifically agrees that such Long Range Forecasts and Rolling Forecasts submitted by Accentia will be for
general planning purposes only. Prior to January 1 of each calendar year, beginning with the Commencement Date for Annual Forecasts, Accentia will provide to Baxter in writing a monthly forecast of Accentias requirements for each Product
for the next succeeding calendar year (both of the foregoing hereby the Annual Forecast). Prior to the commencement of each calendar quarter, Accentia may in its discretion revise its forecast for the subsequent quarter(s) (each
such revised forecast, a Revised Forecast), provided that each such Revised Forecast shall reflect no quarterly amount more than one hundred twenty percent (120%) of the most recent quarterly forecast amount for such quarter.
During each calendar quarter, Baxter shall supply Accentia with the quantity of Product ordered by Accentia, unless the quantity for any calendar quarter exceeds one hundred twenty percent (120%) of the Annual Forecast for such calendar
quarter, in which event Baxter shall use good faith efforts to supply quantities in excess of one hundred twenty percent (120%) of the Annual Forecast for such calendar quarter. In no event shall Accentia order and purchase in any calendar
quarter less than eighty percent (80%) of the Annual Forecast for such calendar quarter.

3.3
Orders. From time to time during the duration of this Agreement, on or before the tenth (10th) calendar day of the month Accentia may submit a written purchase order for the Product to Baxter with a requested delivery date not less than ninety days after the date such order is received, as
provided in Section 3.1. Baxter shall provide a confirmation of receipt of each purchase order setting forth the delivery date that Baxter will meet and setting forth Baxters filling date for such order, in all cases subject to
Section 5.3. Upon Accentias receipt thereof, such purchase order shall become a Firm Purchase Order and payment in full from Accentia to Baxter shall be due unless other payment terms are mutually agreed to by the
Parties in writing. If Baxter is unable to meet the specified delivery date, except when caused by Accentias breach of the terms hereof or failure to pay the invoice amount in a timely manner, Baxter shall so notify Accentia and provide to
Accentia an alternative delivery date which shall not be more than thirty (30) calendar days later than the initial delivery date designated by Baxter in its purchase order confirmation. Terms and conditions for orders that exceed the most
recent forecasts shall be agreed upon by the parties on a case by case basis.

3.4 Precedence of the Terms of the
Agreement. No modification or amendment to the terms and conditions of this Agreement shall be effected by or result from the receipt acceptance, signing or acknowledgement by either party of the purchase orders, confirmations, invoices,
shipping documents or other business forms issued by either party, save in respect of quantities, prices, and delivery dates to the extent such quantities, prices and delivery dates do not conflict with the terms and conditions of this Agreement.

|4. | Payments.

4.1 Net
Sales Payment.

(a) General. In consideration of the clinical development, marketing, regulatory and other
manufacturing and development costs which have been incurred by Baxter prior to the execution of this Agreement, Accentia shall pay to Baxter, on a quarterly basis, a payment of two and one-half percent (2.5%) of Net Sales of Accentia Product
used in treatments included under Clinical Field or Exclusive Clinical Field, calculated on a calendar quarter basis (each such payment, a Net Sales Payment).

(b) Subdistributors. In the event any Subdistributor is engaged in the sale, distribution, promotion, marketing or other disposition of the Accentia Product, Accentia shall pay to Baxter, on a
quarterly basis, a payment of two and one-half percent (2.5%) of Net Sales by such Subdistributor of Accentia Product for the indication of multiple sclerosis, calculated on a calendar quarter basis (each such payment, a Subdistributor Net
Sales Payment). In the event Accentia desires to sublicense rights to the Accentia Product to a Subdistributor for any indication other than multiple sclerosis, the Parties shall negotiate in good faith a commercially reasonable payment rate
with respect to such Subdistributor and the particular indication; the Parties acknowledge that such payment rate is expected to reflect amounts payable to Baxter of up to two and one-half percent (2.5%) of Net Sales by such Subdistributor, or such
lesser amount as the Parties may mutually agree, provided that no Subdistributor shall be permitted to sell, distribute, promote, market or otherwise dispose of the Accentia Product until such payment rate is determined.

For the avoidance of doubt, there shall be no payment made to Baxter under Section 4.1(a) with respect to sales or other
dispositions by a Subdistributor for which Baxter is paid in full pursuant to Section 4.1(b).

(c) Sales
Report. Accentia shall report to Baxter the basis for any payment calculation (i.e. Net Sales) for Accentia Product sales (the Sales Report) within sixty (60) days following the end of each calendar quarter. In the event
of a good faith dispute by Baxter, Accentia shall permit Baxter to audit Accentias books and records with respect to the Accentia Product, upon reasonable prior written notice, but not more frequently than once in any given twelve
(12) month period. For the avoidance of doubt, such audit may include a review of Accentia financial data as well as data with respect to Subdistributor financial data as it relates to the Accentia Product, including with respect to royalties
or similar payments made to Accentia.

EXHIBIT A

ALTERNATIVE DISPUTE RESOLUTION

(a) To the extent not resolved by mediation pursuant to Section 11.1 above, any dispute, claim or controversy arising out of or relating to this Agreement or the breach, termination,
enforcement, interpretation or validity thereof, including the determination of the scope or applicability of this Agreement to arbitrate, shall be determined by binding arbitration. The arbitration shall be governed by the International Institute
for Conflict Prevention & Resolution (CPR) pursuant to its Non-Administered Arbitration Rules and Procedures. References herein to any arbitration rules or procedures mean such rules or procedures as amended from time to
time, including any successor rules or procedures, and references herein to the CPR include any successor thereto. The arbitration shall be before three (3) arbitrators. Each Party shall designate one arbitrator in accordance with the
screened appointment procedure provided in Rule 5.4 of the CPR Rules. The two Party-appointed arbitrators will select the third, who will serve as the panels chair or president. All three arbitrators shall have experience in
commercial disputes within the healthcare industry. The place of the arbitration shall be in Chicago, Illinois (United States of America) and the arbitration shall be conducted in the English language. This arbitration provision, and the arbitration
itself shall be governed by the Federal Arbitration Act, 9 U.S.C. §§ 1-16. The panel of arbitrators shall have no power to award non-monetary or equitable relief of any sort. The arbitrators are not empowered to award recovery of
attorneys fees to the prevailing Party. Except to the extent expressly permitted in this Agreement with respect to indemnity claims, (i) the arbitrators are not empowered to award damages in excess of compensatory damages and
(ii) each Party expressly waives and foregoes any right to recovery of attorneys fees, or any consequential, punitive, special, exemplary or similar damages or lost profits unless a statute requires that actual damages be increased in a
specified manner. The arbitrators shall have no power or authority, under the CPR Rules for Non-Administered Arbitration or otherwise, to relieve the Parties from their agreement hereunder to arbitrate or otherwise to amend or disregard any
provision of this Agreement, including the provisions of this section (a). The award of the arbitrators shall be final, binding and the sole and exclusive remedy to the Parties. Either Party may seek to confirm and enforce any final award entered in
arbitration, in any court of competent jurisdiction. The cost of the arbitration, including the fees of the arbitrators, shall be borne by the Party the arbitrator determines has not prevailed in the arbitration.

(b) A hearing (which shall last no longer than eight (8) Business Days) before the arbitrators so appointed shall be held within one
hundred twenty (120) days after the appointment of the third arbitrator. The Parties shall submit post-hearing briefs within ten (10) days after the end of such hearing, and the arbitrators shall render their award no later than thirty
(30) days after the end of such hearing. Any dispute regarding discovery, or the relevance or scope thereof, shall be determined by the arbitrators, which determination shall be conclusive. The arbitrators may proceed to an award
notwithstanding the failure of the other Party to participate in the proceedings. Discovery shall be limited to the mutual exchange by the Parties and their Affiliates of documents relevant to the dispute, controversy or claim. All requests for such
documents must be submitted to the other Party within forty-five (45) days after the third arbitrator is appointed, as described above. Each Party shall have thirty (30) days to respond to such requests. All discovery shall be completed
within ninety (90) days following the appointment of the arbitrators. All costs and/or fees relating to the retrieval, review and production of electronic discovery shall be paid by the Party requesting such discovery. Document production may
be further limited, at the discretion of the arbitrators. At the request of a Party, the arbitrators shall have the discretion to order examination by deposition of witnesses to the extent the arbitrator deems such additional discovery relevant and
appropriate. Depositions shall be limited to five (5) per Party, shall be held within 45 days of the grant of a request, and each deposition shall not be longer than seven (7) hours, unless otherwise ordered by the arbitrators or
stipulated by the Parties. Additional depositions may be scheduled only with the permission of the arbitrators, and for good cause shown. Each deposition shall be limited to a maximum of one days duration. All objections are reserved for the
arbitration hearing except for objections based on privilege and proprietary or confidential information. The Parties shall not utilize any other discovery mechanism, including, international processes and U.S. federal statues, to obtain additional
evidence for use in the arbitration. The arbitrators shall be authorized to grant interim relief, including to prevent the destruction of goods or documents involved in the dispute, protect trade secrets and provide for security for a prospective
monetary award.

EXECUTION VERSION



(c) Notwithstanding anything contained in this Exhibit A to the contrary, each
Party shall have the right to institute judicial proceedings against the other Party, or anyone acting by, through or under such other Party, in order to enforce the instituting Partys rights hereunder through specific performance, injunction
or similar equitable relief with respect to intellectual property or confidentiality matters. The statute of limitations of the State of Illinois (United States of America) applicable to the commencement of a lawsuit shall apply to the commencement
of an arbitration hereunder, except that no defenses shall be available based upon the passage of time during any negotiation or mediation called for by Section 11.1.

(d) To the extent that arbitration may not be legally permitted hereunder and the Parties to any dispute hereunder may not at the time of
such dispute mutually agree to submit such dispute to arbitration, any Party may commence a civil action in a court of appropriate jurisdiction in the United States of America, including, without limitation, those located in Chicago, Illinois, which
court shall apply the laws of the State of Illinois (United States of America) to resolve disputes hereunder. The court shall have no authority to award recovery attorneys fees to the prevailing Party or damages in excess of compensatory
damages and each Party expressly waives and foregoes any right to recovery of attorneys fees, or any consequential, punitive, special, exemplary or similar damages or lost profits unless a statute requires that actual damages be increased in a
specified manner. Nothing contained in this Exhibit A shall prevent the Parties from settling any dispute by mutual agreement at any time.

(e) If an arbitral award does not impose an injunction on the losing Party or contain a money damages award in excess of USD $1,000,000, then the arbitral award shall not be appealable and shall only be
subject to such challenges as would otherwise be permissible under the Federal Arbitration Act, 9 U.S.C. §§ 1-16. In the event that the arbitration does result in an arbitral award, which imposes an injunction or a monetary award in excess
of USD $1,000,000, such award may be appealed to a tribunal of appellate arbitrators via the CPR Arbitration Appeal Procedure.

(f) Except as may be required by law, neither a Party nor an arbitrator may disclose the existence, content, or results of any
arbitration hereunder without the prior written consent of both Parties.
