	5 -	PURCHASE ORDERS 

 5.1 Purchase Commitment Cadence agrees to
purchase from Solvay and Solvay agrees to manufacture and supply to Cadence Bulk Drug Substance through Purchase Orders. Cadence recognizes Solvay as its primary supplier for Bulk Drug Substance and, except as otherwise provided in this
Section 5.1 or in the License Agreement, Cadence shall order from Solvay a minimum of ##### of the Aggregate Annual Requirement. 
 (a) For the
avoidance of doubt, the Parties hereto agree that nothing in this Agreement or in the License Agreement is intended to limit or restrict, in any manner, the rights of Cadence, its Affiliates and Sublicensees, to make, have made, purchase, use,
import, export, market or sell any quantity of Omiganan Drug Substance that is made by any means other than by the Licensed Process. 
 (b) Insufficient
Capacity, Unwillingness or Inabililty to Supply: If Solvay’s Production Capacity for #####, as provided to Cadence by Solvay in accordance with Sub-Clause 4.2 by #####, is less than the Binding Requirement for #####, or if Solvay otherwise
notifies Cadence that it is unwilling or unable to supply conforming Bulk Drug Substance to Cadence in amounts indicated in the Binding Requirement for #####, then during ##### Cadence shall be entitled to purchase from the Secondary Source more
than ##### percent (#####%) of the Annual Aggregate Requirement by purchasing additional quantities of Bulk Drug Substance that equal the amounts that Solvay is unwilling or unable to supply. 
  
 ##### Certain information on this page has been omitted and filed separately with the
Commission. Confidential treatment has been requested with respect to the omitted portions. 







 (c) Failure to Deliver: If Solvay fails to deliver at least ##### percent (#####%) of the amount of
conforming Bulk Drug Substance ordered by Cadence according to an accepted Delivery Schedule for delivery #####, Cadence shall be entitled to purchase from the Secondary Source more than ##### percent (#####%) of the Annual Aggregate Requirement by
purchasing additional quantities of Bulk Drug Substance that equal the amounts that Solvay has not been able to deliver. 
 (d) In addition to the remedies
set forth in Sub-Clauses 5.1(b) and 5.1(c), if either: 
 (i) Solvay’s Production Capacity is insufficient, or if Solvay indicates it is otherwise
unwilling or unable to supply conforming Bulk Drug Substance to Cadence in amounts indicated in the Binding Requirements, for #####, or 
 (ii) Solvay fails
to deliver at least ##### percent (#####%) of the amount of conforming Bulk Drug Substance ordered by Cadence according to an accepted Delivery Schedule for delivery for #####, 
 in addition to any other remedies that Cadence may have under this Agreement, at law or in equity, Cadence’s requirement to purchase from Solvay a minimum of ##### percent (#####%) of the Aggregate Annual
Requirement shall henceforth be automatically reduced to such level as Solvay has demonstrated, to Cadence’s reasonable satisfaction, it is consistently able to supply. 
 (e) Cadence shall be released from its obligation to purchase Bulk Drug Substance from Solvay, and shall thus be entitled to purchase all of its requirements for Bulk Drug Substance from the Secondary Source, as set
forth in Sub-Clause 10.7 of this Agreement. 
 5.2 Supply Commitment Solvay shall accept purchase orders placed according to the provisions of Article
5.3 and shall be obligated to supply the amount of Bulk Drug Substance specified in the purchase order on the timeline specified therein, subject to any limitations as to the quantities of Bulk Drug Substance that may be included in such purchase
order(s) in accordance with Article 5.3. In the event that Solvay receives one or more purchase orders for delivery in a given year which would, in aggregate, exceed the most recent Production Capacity for such year, Solvay shall promptly notify
Cadence and shall accept such purchase order(s) for the ordered amounts of Bulk Drug Substance up to the Production Capacity for the applicable year. 
 5.3 Timing of Purchase Orders 
 5.3.1 Purchase Orders for #####. 
 5.3.1.1 Initial Purchase Order #####. At any time after #####, Cadence may issue an initial purchase order for deliveries of Bulk Drug Substance during

 5.3.1.2 Supplemental Purchase Orders #####. Cadence may elect to increase the amount it has ordered for delivery ##### by providing Solvay with a
supplemental purchase order by no later than #####. Solvay shall accept such supplemental purchase order; provided, however, that Solvay shall not have an obligation to provide more than ##### percent (#####%) of the quantity ordered in the
initial purchase order for deliveries in #####. 
  
 ##### Certain information
on this page has been omitted and filed separately with the Commission. Confidential treatment has been requested with respect to the omitted portions. 







 5.3.2 Purchase Orders for Subsequent Years. 
 5.3.2.1 Initial Purchase Orders for Subsequent Years. Beginning in #####, at any time before ##### of any such year (“Year X”), Cadence
may issue and Solvay shall accept an initial purchase order for deliveries of Bulk Drug Substance during #####. 
 5.3.2.2 Supplemental Purchase
Orders for Subsequent Years. For years beginning with ##### (“Year X”), Cadence may elect to increase the amount it has ordered for delivery in ##### by providing Solvay with a supplemental purchase order by no later than #####.

facilities. Bulk Drug Substance shall be labeled and packaged according to the Specification in a shipping container supplied by Solvay. Solvay shall invoice such shipping containers to Cadence at Solvay’s direct cost. Title and risk of loss as
to all Bulk Drug Substance shipped shall pass to Cadence or Cadence’s designee upon delivery to the carrier designated by Cadence. In the event that, upon Cadence’s request pursuant to Article 6, shipment of a Lot is not made promptly
after the completion of manufacture of such Lot and therefore such Lot is placed into inventory, risk of loss shall remain with Solvay until such Bulk Drug Substance is delivered to the carrier designated by Cadence. All customs, duties, costs,
taxes, insurance premiums, and other expenses of such transportation and delivery (whether shipment of Bulk Drug Substance is made promptly after completion of manufacture or such Bulk Drug Substance is placed into inventory at Cadence’s
request), shall be at Cadence’s expense. 
 8.2 Documents Included with Bulk Drug Substance Shipment Solvay shall provide Cadence with a
certificate of analysis, signed by the responsible quality officer of Solvay, with each lot of Bulk Drug Substance shipped to Cadence, and additional documentation as specified in the Quality Agreement. 
 8.3 Non-Conforming and Non-Complying Product Bulk Drug Substance supplied hereunder shall be produced by Solvay in compliance with all Applicable Laws,
including without limitation GMPs, and in conformance with the Specification. 
 Solvay shall test and inspect each lot of Bulk Drug Substance for compliance
with the Specifications prior to release and shipment of such Bulk Drug Substance to Cadence. Cadence has the right to reject and return, at the expense of Solvay, all or any portion of any shipment of Bulk Drug Substance that deviates from the
Specifications or GMPs or is adulterated, without invalidating any remainder of such shipment. Cadence or its designated agent shall inspect the Products manufactured by Solvay upon receipt of such Bulk Drug Substance and related Certificate(s) of
Analysis and shall give Solvay notice of all claims for Bulk Drug Substance that deviate from the Bulk Drug Substance Specifications or GMPs within sixty (60) days after Cadence’s receipt of such Bulk Drug Substance and related
Certificate(s) of Analysis (or, in the case of any defects not reasonably susceptible to discovery upon receipt of the Product, within thirty (30) days after discovery thereof by Cadence, but in no event after the expiration date of the Bulk
Drug Substance). If no such notice of rejection of non-conforming Bulk Drug Substance is submitted, Cadence shall be deemed to have accepted such delivery of the Bulk Drug Substance. 
  
 ##### Certain information on this page has been omitted and filed separately with the Commission. Confidential treatment has been
requested with respect to the omitted portions. 







 8.4 Non-Certified Delivery At Cadence’s request, Solvay shall deliver Bulk Drug Substance to Cadence or
Cadence’s designee prior to Solvay issuing a Certificate of Analysis applicable to such Bulk Drug Substance (“Non-Certified Delivery”). Cadence acknowledges that any request for Non-Certified Delivery shall imply a commitment
by Cadence to Solvay that Drug Product manufactured using any such Bulk Drug Substance shall not be administered to humans until the applicable Certificate of Analysis for such Bulk Drug Substance is ultimately issued by Solvay. 
 8.5 Procedures After Notice of Rejection After notice of rejection of Bulk Drug Substance is given in accordance with Article 8.3 above, Solvay shall
promptly replace such Bulk Drug Substance not later than ##### after Solvay’s receipt of Cadence’s notice, regardless of whether Solvay agrees that such rejection is warranted. If Solvay disagrees with Cadence’s determination that a
certain Lot or Sub-Lot does not meet the requirements, Solvay shall notify Cadence of such disagreement within fifteen (15) days after receipt of Cadence’s notice. A sample of such Bulk Drug Substance shall be submitted to a mutually
acceptable third party laboratory; the fees and expenses of such laboratory testing shall be borne entirely by the Party against whom such findings are made. Such third party laboratory shall determine whether such Bulk Drug Substance meets the
requirements of Article 8.3 above and, and the Parties agree that such laboratory’s determination shall be final and determinative. If Solvay does not challenge Cadence’s rejection of a certain Lot or Sub-Lot within the
fifteen (15) day period described above, or if Solvay challenges the rejection and subsequently agrees that the applicable Lot or Sub-Lot was properly rejected, or if the third party laboratory determines that a Lot or Sub-Lot does not meet the
requirements of Article 8.3, Solvay shall be responsible for all costs associated with the replacement of the non-conforming Bulk Drug Substance, including the manufacturing and shipping charges to deliver the replacement Bulk Drug Substance to
Cadence. If Cadence is determined to have improperly rejected such Bulk Drug Substance, then Cadence shall be responsible for such costs. 
 Unless Solvay
requests the destruction of rejected Bulk Drug Substance within thirty (30) days of receipt of Cadence’s notice of rejection of such Bulk Drug Substance, Cadence shall promptly return such Bulk Drug Substance to Solvay, at Solvay’s
cost and FCA (Incoterms 2000) Cadence’s (or its designee’s) facilities, and according to shipping instructions in the Specification. Cadence shall, upon receipt of a request for destruction of the material, destroy such Bulk Drug Substance
promptly, properly and at Solvay’s expense, and provide Solvay with certification of such destruction. 
  

	9 -	PRICE AND PAYMENTS 

 9.1 Prices Cadence agrees to pay to
Solvay for the manufacture of Bulk Drug Substance according to the applicable lot sizes and pricing levels set forth in Appendix A. The applicable pricing level for any Purchase Order shall be determined as follows:

renewal period that it does not wish to renew. For clarity, if either Party desires that this Agreement terminate at the end of the initial term, the Party must give written notice before the fourth (4th) anniversary of the Program Commencement Date.  
  

	10.2	Termination This Agreement may be terminated: 

 (a) upon mutual
written agreement between the Parties; 
 (b) by either Party as a result of a material breach or default in the performance of any obligation, condition or
covenant of this Agreement by the other Party, if such default or noncompliance shall not have been remedied within ninety (90) days after receipt by the defaulting Party of a notice thereof from the terminating Party, unless the defaulting
Party is in the process of attempting in good faith to remedy such default, in which case the ninety (90) day cure shall be extended by an additional sixty (60) days; 
 (c) by either Party upon ten (10) days written notice to the other Party if the other Party ceases to do business, or makes any assignment of substantially all of its assets for the benefit of creditors, or

 (d) by Cadence upon ninety (90) days written notice to Solvay, in the event that a third party asserts that the
activities carried out under this Agreement infringe its intellectual property rights (including patent rights) and, following discussions with Solvay during such ninety (90) day period, including discussions regarding any assessment performed
by Solvay showing that the aforementioned activities do not infringe such third party’s intellectual property rights, Cadence reasonably concludes that there is a bona fide, unacceptable risk that such activities infringe or shall infringe such
intellectual property rights. In reaching its conclusion, Cadence, however, agrees to take into account in good faith whether Solvay (i) has entered into negotiation with the concerned third party for acquiring a license under its intellectual
property rights, or (ii) has started to modify the Licensed Process such that it will not infringe such third party’s intellectual property rights; 
 (e) by Cadence upon sixty (60) days prior written notice to Solvay effective upon the termination of the Cadence-Migenix Agreement; or

the effective date of such termination, including but not limited to: 
 (a) the obligation of Solvay to deliver said Bulk Drug Substance, 
 (b) the obligation of Cadence to accept and, upon acceptance, pay for any of said Bulk Drug Substance, and 
 (c) any other such obligation of either Party under Articles 6, 7, 8, 9, 10, 11, 13, 14 and 15. 
 10.4 In the
event of termination of this Agreement for whatever cause, in addition to the other obligations of the Parties hereunder, each Party shall, within thirty (30) days after the receipt of a timely request from the other Party, destroy or return to
the other Party or to the other Party’s designee all of such other Party’s property, including all Confidential Information, in its possession, except to the extent required to be retained by Applicable Law or to comply with such
Party’s continuing obligations hereunder or under the License Agreement. 
 10.5 After the expiration, or early termination, of this Agreement:

 (i) the confidentiality, non disclosure and restricted use obligations set forth hereunder shall continue thereafter in accordance with Sub-Clause 12.5;
and 
 (ii) the license granted to Cadence under Sub-Clauses 2.1.2(a) shall continue thereafter, except that such license shall cease immediately upon
termination by Solvay pursuant to Sub-Clause 10.2(b), 10.2(c), or 10.2(f). 
 10.6 In the event of non-renewal of this Agreement by Cadence pursuant
to Sub-Clause 10.1, or termination of this Agreement by Cadence pursuant to Sub-Clause 10.2(d) or 10.2(e), or by Solvay pursuant to Sub-Clause 10.2(b), 10.2(c), or 10.2(f), the License Agreement shall immediately terminate.

Agreement by Cadence pursuant to Sub-Clause 10.2(b) or 10.2(c), or by mutual agreement pursuant to Sub-Clause 10.2(a), 
 (a) the rights granted to Cadence
under the License Agreement shall continue, 
 (b) Cadence shall be released from its obligation to purchase Bulk Drug Substance from Solvay, and shall thus
be entitled to purchase all of its requirements for Bulk Drug Substance from the Secondary Source, and 
 (c) concerning the payment of royalties by Cadence
to Solvay in consideration for such continuing rights: 
 (i) the royalty rate specified in Sub-Clause 6.1.1(b)(ii) of the License Agreement shall apply in
case of termination of this Agreement by Solvay pursuant to Sub-Clause 10.1, or by Cadence pursuant to Sub-Clause 10.2(b), 
 (ii) the royalty rate specified
in Sub-Clause 6.1.1(b)(i) of the License Agreement shall apply in case of termination of this Agreement by mutual agreement pursuant to Sub-Clause 10.2(a), and 
 (iii) no royalty shall be due by Cadence in case of termination of this Agreement by Cadence pursuant to Sub-Clause 10.2(c). 
 10.8 Except
as otherwise expressly provided hereunder or under the License Agreement, the termination of this Agreement shall not affect the License Agreement.

such illegal or unenforceable provisions with suitable substitute provisions which shall maintain as far as possible the purposes and the effect of this Agreement. 
 15.15 Waiver 
 Failure of either Party to insist upon strict observance of or compliance with any of the terms of this Agreement in one or

	(b)	For clarity, the failure of Migenix and Solvay to enter into a supply or license agreement, as contemplated under Sub-Clause 15.16(a), shall not be considered a material breach or
default in the performance of any obligation, condition or covenant of this Agreement by Solvay, and shall thus not serve as the basis for the termination of this Agreement by Cadence under Sub-Clause 10.2(b). 

  

	(c)	References in this Section to the Cadence-Migenix Agreement means references to the form of such agreement provided to Solvay prior to the Effective Date. The rights of Migenix

 APPENDIX A 
 Bulk Drug Substance Price 
 The reference price for Bulk Product at the specification, per gram, FCA Solvay’s
manufacturing facility, shall be: 
 ##### 
 The
unit price for Bulk Product for a specific Purchase Order shall be computed by multiplying the above- specified reference price by two corrective factors determined in the following manner: 
  

	 	•	 	 Inflation correction factor: 


 Divide the
value of the most recently published Producer Price Index “Total Market” published by the Belgian Ministry of Economy Index Service (www.statbel.fgov.be/indicators/opi_en.asp) as of the date of the relevant Purchase Order by
the value of such Producer Price Index “Total Market” as of #####. 
  

	 	•	 	 Exchange rate correction factor: 


 The
reference prices for Bulk Drug Substance, above, are based upon an exchange rate of ##### USD($) per Euro(€). If, as of the date of a Purchase Order, the Exchange Rate is less than ##### or greater than #####, then subtract ##### from the
Exchange Rate as of the date of the Purchase Order, multiply the result by ##### (#####), and then add ##### (#####) to that product to identify the factor. The “Exchange Rate” shall be the most recently published value, as of the
date of the Purchase Order, of the amount in USD required to purchase one (1) EUR, as published in the Wall street Journal, New York Edition.
