payment more than ninety (90) days after it is due: (i) BUYER shall pay a monthly late payment penalty equal to 1.0% of the amount due but unpaid sixty (60) days from the due date and as of each thirty (30) day period thereafter,

Order, including, but not limited to, preprinted terms and conditions, that are inconsistent with the terms of this Agreement, shall not apply or be enforceable by BUYER. The volume of a minimum Purchase Order of Product shall be at least one
commercial batch of Product unless an alternate configuration or quantity is mutually agreed upon by the parties.

stated in the applicable Purchase Order without any rescheduling or any other charges. 
 4.5 Cancellation of Purchase Orders. In the
event of the cancellation of a Purchase Order that will not be filled at a later date, BUYER will be responsible for the cost to SUPPLIER of any materials received by SUPPLIER whose use is exclusively for manufacturing of the Product, but only to
the extent that the materials were to be used in fulfilling the cancelled Purchase Order. Upon payment by BUYER for such materials, they shall become the property of the BUYER and SUPPLIER shall disposition such materials as BUYER directs and at
BUYER’s expense. 
 5. Raw Materials and Other Supplies. 

5.1 BUYER Supplies. Until SUPPLIER is able to procure some or all BUYER Supplies, BUYER shall be responsible for providing and supplying

include API), BUYER shall deliver or procure delivery of BUYER Supplies to SUPPLIER in sufficient quantities, quality, and condition, and at least 60 days in advance of a required Delivery Date, to enable SUPPLIER to meet its obligations under this
Agreement and the relevant Purchase Order. Where applicable, BUYER Supplies shall be provided with appropriate release documentation. BUYER’s failure to timely satisfy the requirements of this section shall excuse SUPPLIER’s failure to
meet a required Delivery Date to the extent that such BUYER’s failure caused or materially contributed to SUPPLIER’s failure. 

5.3 Supply Failure. For each binding Purchase Order on which SUPPLIER fails to deliver at least 90% of the binding, ordered quantity of
the Product within fifteen (15) days after the scheduled delivery date, SUPPLIER shall be liable to BUYER for (i) any cost difference for acquiring the shorted amount from an alternate site, and (ii) the greater of (a) 10% of the Product
Price for the units not timely delivered, or (b) any amounts paid by BUYER to any customer as penalties due to SUPPLIER’s failure to supply any Product on a timely basis (collectively the “Supply Failure Penalty”). BUYER shall
have the right to offset the Supply Failure Penalty against any Profit Split owed to SUPPLIER. 
 5.4 SUPPLIER Supplies. SUPPLIER
shall be responsible to provide and supply, at no additional cost to BUYER, the supplies listed in Exhibit E (the “SUPPLIER Supplies”).

be delivered directly from BUYER’s vendor to SUPPLIER at BUYER’s expense. With each shipment of API, BUYER shall provide, or require the vendor to supply, SUPPLIER with a completed copy of the vendor’s certificate of analysis for the
API containing test results. BUYER may elect to have SUPPLIER undertake identification testing of each shipment and/or testing for compliance with the Specifications. If the API fails any testing by SUPPLIER, SUPPLIER will immediately provide BUYER
notice of such failure along with details of the testing and reason(s) for failure, and SUPPLIER shall be excused from its obligation to manufacture or supply Product to BUYER until API meeting approved Specifications is delivered to SUPPLIER. Upon
such delivery, SUPPLIER shall have a reasonable time in which to supply Product to BUYER that satisfies and complies with the Specifications. 

5.6 Active Pharmaceutical Ingredient and Product Handling. SUPPLIER shall store the Active Pharmaceutical Ingredient and the Product at
a temperature and in accordance with other special handling requirements set forth in the Specifications, DEA (if applicable) and FDA cGMP.

(i) SUPPLIER Supplies and (ii) the Product (to the extent of value added by SUPPLIER over the value of BUYER Supplies, which become a part of such Product) until delivery of the Product to the Carrier, at which time risk of loss shall pass
to BUYER. Notwithstanding anything to the contrary contained herein, in no event shall SUPPLIER’s liability exceed the cost of BUYER Supplies lost, damaged, destroyed, or otherwise unusable. Notwithstanding the foregoing, any loss or damage to
BUYER Supplies, SUPPLIER Supplies, or the Product resulting from acts by SUPPLIER taken in accordance with the Specifications, cGMP, or BUYER instructions shall be borne by BUYER. SUPPLIER shall bear the risk of loss of BUYER Supplies due to
SUPPLIER’s willful misconduct or negligence, including but not limited to SUPPLIER’s failure to comply with the Specifications, cGMPs, or BUYER instructions.

7.1 Inspection. On an annual basis, or as needed for cause where quality issues are identified, BUYER’s employees shall have the
right, at a mutually agreeable time and upon mutually agreeable terms, during SUPPLIER’s regular business hours, to enter the Facilities for the purpose of observing the manufacturing of the Product, inspecting the quality of finished Product,
obtaining samples of Product, and/or conducting quality assurance audits. BUYER shall have the right to suspend orders until correction in the event it uncovers material manufacturing or Product quality concerns that SUPPLIER is unable or unwilling
to remedy within a reasonable period of time. BUYER’s employees who inspect SUPPLIER’s Facilities shall comply with SUPPLIER’s regulations, rules, and practices, and BUYER assumes all risk of loss and shall indemnify, defend, and hold

all federal and state environmental 












 
and occupational safety and health requirements. Such procedures shall be included in a separate document and shall be followed by SUPPLIER in performing services under this Agreement. SUPPLIER
shall, in accordance with BUYER instructions, ship rejected API, Product, and BUYER Supplies to such destination as BUYER’s instructions shall designate in writing. The expense for disposal or reclamation of rejected Product, API, BUYER
Supplies, and other waste shall be borne by BUYER; provided, however, the expense for disposal of rejected Product due to failure of SUPPLIER to perform its obligations under this Agreement shall be borne by SUPPLIER. SUPPLIER will not dispose of

 7.6
Product Inspection. SUPPLIER will test and inspect each lot of Product for compliance with Specifications, and shall certify in writing such compliance to BUYER, prior to release and shipment to BUYER. If within 30 days after receipt of pre-shipment samples or the lot of Product by BUYER at its facility, BUYER notifies SUPPLIER in writing that such lot contains Non-Conforming Product as determined by any
information available to BUYER, SUPPLIER shall replace Non-Conforming Product at SUPPLIER’s expense (such expense to include the cost of API, BUYER Supplies, and all components and other materials) within
forty-five (45) days of such notice. SUPPLIER shall pay for shipping charges to deliver such replacement Product to BUYER. Non-Conforming Product shall, at BUYER’s election, either (i) be
returned to SUPPLIER within a reasonable period of time, or (ii) be destroyed by BUYER at SUPPLIER’s expense with proof of destruction. Notwithstanding the foregoing, if BUYER first discovers any nonconformance that would not have been
readily discoverable from a review of the associated documentation provided by SUPPLIER or the packaging for a particular Product shipment at the time of delivery (a “Latent Defect”), BUYER shall have a continuing right to notify SUPPLIER
within thirty days after the discovery of the Latent Defect. 
 7.7 Disputes with Respect to Rejection. If SUPPLIER disputes
BUYER’s rejection of all or part of any shipment of the Product, and such dispute is not resolved by mutual agreement between the parties within sixty (60) days of BUYER’s notice of rejection, such dispute shall be resolved by an
independent FDA approved testing organization or consultant of recognized repute within the U.S. pharmaceutical industry mutually agreed upon by the parties, the appointment of which shall not be unreasonably withheld or delayed by either party. The
determination of such testing entity with respect to all or part of any shipment of the Product shall be final and binding upon the parties, but only as to the reasons given by BUYER in rejecting the shipment or portion thereof and shall have no
effect on any matter for which said entity did not render a determination. The fees and expenses of the third party making the determination shall be paid by BUYER if the Product is found to be in compliance with the Specifications, cGMPs, and BUYER
instructions; otherwise, such fees and expenses shall be paid by SUPPLIER. 












 8. Warranty. 

8.1 SUPPLIER Warranty. SUPPLIER warrants that it shall manufacture and supply the Product in compliance with this Agreement, and that
the Product, when delivered to the Carrier, will meet the Specifications and shall not be Non-Conforming Product; provided, however, this warranty shall not apply to defects in Product (i) resulting from
or occurring despite SUPPLIER’s compliance with the Specifications, cGMPs, and any express instruction of BUYER, (ii) resulting from the quality or suitability of any BUYER Supplies, or (iii) if the Product is abused, altered,
improperly stored, or repackaged after leaving SUPPLIER’s possession. No warranty is made as to the quality or suitability of any BUYER Supplies or the Product Performance Characteristics or other performance characteristics of the Product.
Notwithstanding anything contained herein, in no event shall SUPPLIER’s liability with respect to a claim whether by BUYER or any third party arising out of or relating to SUPPLIER’s alleged breach of warranty exceed the limit of insurance
required under section 10.1 of this Agreement. 
 8.2 Warranty Procedures. To claim any rights or to enforce any warranty provisions
against SUPPLIER, written notice of a warranty claim must be given by BUYER to SUPPLIER within one hundred eighty (180) days after the Product is delivered to the Carrier. Any Product that BUYER believes breaches the warranty set forth in this
section must be held by BUYER for SUPPLIER’s inspection and testing and, upon SUPPLIER’s request, returned to original Ex-Works place of shipment point, freight prepaid. Upon SUPPLIER’s
reasonable determination that the Product is defective and that such defect is due to SUPPLIER’s failure to comply with the Specifications, the cGMP, or other negligent or wrongful act or omission by SUPPLIER, SUPPLIER shall, at BUYER’s
election, either (i) manufacture, package, and label additional Product to replace such defective Product at the original Ex-Works place of shipment point (subject to BUYER providing, at SUPPLIER’s
expense, necessary API and BUYER Supplies); or (ii) credit BUYER with an amount equal to the costs of all API and BUYER Supplies in the defective Product. Upon SUPPLIER’s reasonable determination that the Product is not defective, SUPPLIER
and BUYER shall submit the Product to an independent third party for testing. If such third party determines that the Product is defective and that such defect is due to SUPPLIER’s failure to comply with the Specifications, the cGMP, or other
negligent or wrongful act or omission by SUPPLIER, SUPPLIER shall, at BUYER’s election, either (i) manufacture, package, and label additional Product to replace such defective product at the original
Ex-Works place of shipment point (subject to BUYER providing, at SUPPLIER’s expense, all necessary API and BUYER Supplies); or (ii) credit BUYER with an amount equal to the costs of all API and BUYER
Supplies in the defective Product. If such third party determines that the Product is not defective or that such defect is not due to SUPPLIER’s failure to comply with the Specifications, the cGMP, or other negligent or wrongful act or omission
by SUPPLIER, then BUYER shall pay the expenses associated with such third party testing and shall accept and pay for the Product. 
 8.3
Exclusive Remedy. The foregoing is BUYER’s sole and exclusive remedy against SUPPLIER for breach of warranty, breach of contract, tortious acts, or any other legal theory arising out of or related to this Agreement. In no event shall
SUPPLIER be liable for incidental or consequential damages. 












 8.4 Other Warranties. ALL OTHER EXPRESS OR IMPLIED WARRANTIES, INCLUDING WITHOUT
LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE EXPLICITLY DISCLAIMED. 
 9. Indemnification for
Third Party Claims. 
 9.1 SUPPLIER Indemnification. SUPPLIER shall indemnify and hold BUYER harmless from any damage,
expense, loss, or liability, including reasonable attorney’s fees, arising out of or resulting from any third party claims against BUYER, where SUPPLIER is at fault by reason of (i) defect of the Product which would be a defect covered
under Section 8, (ii) negligence of willful misconduct of SUPPLIER, or (iii) breach of this Agreement, including failure to perform any act required by or in compliance with SUPPLIER’s obligations under this Agreement or another
breach of this Agreement; provided, however, that SUPPLIER shall not have any obligation to indemnify BUYER to the extent a claim results from the gross negligence or willful misconduct of BUYER. BUYER shall give SUPPLIER notice of any claim for
which BUYER may be entitled to indemnification and shall cooperate with SUPPLIER in the defense of such claims. Notwithstanding the foregoing, at its election, and at its own expense, SUPPLIER (or its insurers) may assume direction and control of
the defense of any such claim. 
 9.2 BUYER Indemnification. BUYER shall indemnify and hold SUPPLIER harmless from any damage,
expense, loss, or liability, including reasonable attorney’s fees, arising out of or resulting from any third party claims made or threatened against SUPPLIER by reason of (i) any failure of BUYER to comply with any law or regulation
regarding the possession, distribution, labeling, or sale of the Product, (ii) the gross negligence or willful misconduct of BUYER, or (iii) any Product Performance Characteristics of a Product that is in compliance with the Specifications
and cGMP; provided, however, that BUYER shall not have any obligation to indemnify SUPPLIER to the extent a claim results from the negligence or willful misconduct of SUPPLIER or SUPPLIER’s breach of this Agreement. SUPPLIER shall give BUYER
notice of any claim for which SUPPLIER may be entitled to indemnification and shall cooperate with BUYER in the defense of such claims.

 11. Confidential Information. 

11.1 Definition. Confidential Information for purposes of this Agreement shall mean any and all trade secrets, know-how of or data about each of the parties, their clients, or their operations, and other matters of a confidential or proprietary nature, including, without limitation, the Product and the Specifications, but
shall not include any of the following information: 
 (i) information which was known to the receiving party, prior to receipt from the
delivering party, as evidenced by the receiving party’s written records; 
 (ii) information which was in the public domain or generally
known to the trade at the time of receipt from the delivering party; 
 (iii) information which, other than by breach of this Agreement,
enters the public domain or becomes generally known to the trade; 
 (iv) information which is disclosed to the receiving party by a third
party who is free to make such disclosure; 
 (v) information which is independently developed by the receiving party without use of the
delivering party’s Confidential Information; or 
 (vi) information which is required to be disclosed by law, regulatory,
administrative, or judicial order. 
 11.2 Term. During the Term and any extension of this Agreement and for a period of five
(5) years thereafter, the parties shall not disclose, communicate, or otherwise make available to any other party and shall not use or deal with in any manner, except as permitted by this Agreement, any Confidential Information of the other;
provided, that with respect to any Confidential Information that constitutes a trade secret of a party, this covenant shall continue for as long as the same remains a trade secret of that party. 












 11.3 Use. Each party agrees to use the Confidential Information of the other only for
the purpose of performing its obligations under this Agreement; shall not copy any Confidential Information of the other except as necessary to perform its obligations under this Agreement; shall limit dissemination of the Confidential Information
of the other to only those of its employees who have a need to know; and shall return all Confidential Information of the other, including any copies, upon the earlier of such party’s request or the termination of this Agreement; provided,
however, a party may retain a copy of the Confidential Information of the other as may be required by law or regulation for record keeping purposes, 

11.4 Disclosure. A party may disclose Confidential Information of the other party to a third person if it is required to do so by
subpoena, court order, law, or regulation. In such event, the party shall, in advance of the disclosure if practical, notify the other of such required disclosure. Each party agrees that the Confidential Information of each party is vital to the
business interests of each party and that any disclosure or unauthorized use thereof would cause irreparable harm. Each party may specifically enforce the obligations of the other under this paragraph, by injunction or otherwise, in addition to and
not in limitation of any other remedies that a party may have at law or in equity. 
 11.5 Discoveries. Discoveries or inventions by
SUPPLIER made in the course of performing this Agreement shall become the property of (a) BUYER, if such discovery or invention relates specifically to the Product or its formulation; or (b) SUPPLIER, if such discovery or invention
improves upon or relates to general manufacturing or production methods applicable to a variety of pharmaceutical products or does not otherwise relate specifically to the Product or its formulation. 

11.6 Prior Agreement. The Parties acknowledge that they are parties to that certain Mutual Confidential Disclosure Agreement by and
between them and having an Effective Date of July 7, 2020 (“the CDA”), and that the CDA remains in full force and effect. The provisions of this Section 11 are intended to supplement, and not to replace, the provisions of the CDA.

received by the other Party no less than three (3) months prior to the end of the Agreement and, in the absence of such notice, the annual (1 year) renewal clause will apply. 

12.2 Termination. Either party may terminate this Agreement for a material breach by the other party by giving the breaching party
written notice, specifying the breach relied on, and giving the breaching party thirty (30) days to cure such breach. If the breach has not been cured (or the breaching party has not commenced a good faith effort to cure) at the end of the
thirty (30) day period, then, upon notice thereof to the breaching party by the other, this Agreement shall terminate. 












 12.3 Bankruptcy. If either party shall file or have filed against it a petition in
bankruptcy, make an assignment for the benefit of its creditors, or have a receiver appointed for its assets, which action shall not be vacated within 60 days after such action, then the other party may terminate this Agreement immediately upon
written notice.

terms and conditions mutually agreed to in a letter of termination executed by BUYER AND SUPPLIER. The terms and conditions contained in such letter of termination (a) may conflict with or add to the terms and conditions of this Agreement; and
(b) shall supersede the terms and conditions of this Agreement, including with respect to survival. 
 12.5 FDA Warning Letter.
This Agreement will terminate only with respect to the affected Product or in its entirety, at the sole discretion of BUYER, immediately upon a ten (10) day written notice by BUYER, following issuance by the US FDA of a “Warning
Letter” to SUPPLIER with respect to one or more of its facilities used, or to be used, to manufacture, test, validate, label, package or store Product. 

12.6 Discontinued Product. BUYER may terminate this Agreement with respect to a specific Product upon 6 (six) months written notice in
the event such Product is discontinued for any reason. 
 12.7 Customer Complaints. BUYER may terminate this Agreement with respect to
a specific Product upon thirty (30) days’ notice in the event that BUYER receives more than 100 documented customer complaints related to Product quality in any one calendar year, which complaints are regarding such Product and due to
reasons that are within SUPPLIER’s control. 
 12.8 Incomplete Tech Transfer. BUYER may terminate this Agreement with respect to
a specific Product upon thirty (30) days’ written notice in the event the Tech Transfer is not complete (including receiving all necessary approvals from FDA) within two (2) years from the Effective Date. 

12.9 Profit Margin. BUYER may terminate this Agreement with respect to a specific Product upon thirty (30) days’ written
notice in the event BUYER’s Gross Profit Margin is below 40% for any two (2) consecutive quarters. In such event, all outstanding purchase orders and the remaining purchase requirement for the calendar year per Section 2.2 will be paid by
BUYER to Nephron within 30 days of termination. 
 12.10 Product Launch. BUYER may terminate this Agreement with respect to a specific
Product upon thirty (30) days’ written notice in the event such Product is not launched within two (2) years from the Effective Date. 












 12.11 Survival. The termination of this Agreement shall not relieve the parties of any
obligation accruing prior to termination, provided that a Purchase Order outstanding as of the effective date of an early termination shall remain in effect only to the extent of work in progress as of the date of notice of termination. Without
limitation as to other rights and obligations that may survive, Sections 8, 9, 10, 11 and 14 shall survive any termination of this Agreement. 
 13.
Independent Contractor. SUPPLIER is an independent contractor for BUYER and the parties are not partners or joint venturers. Except for the Specifications, BUYER Supplies, and BUYER’s right to assure the quality of SUPPLIER’s
services, SUPPLIER shall furnish all expertise, labor, supervision, and facilities necessary for the manufacture and the supply of the Product, maintain all required governmental permits, and comply with all laws regarding the Facilities. 

14. Waiver of Jury Trial. Each party acknowledges and agrees that any controversy which may arise under this Agreement is likely to
involve complicated and difficult issues and, therefore, each such party irrevocably and unconditionally waives any right it may have to a trial by jury in respect of any legal action arising out of or relating to this Agreement. Each party to this
Agreement certifies and acknowledges that (a) no representative of any other party has represented, expressly or otherwise, that such other party would not seek to enforce the foregoing waiver in the event of a legal action,
(b) such party has considered the implications of this waiver, (c) such party makes this waiver voluntarily, and (d) such party has been induced to enter into this Agreement by, among other things, the mutual waivers and
certifications in this section 
 14. 
 15.
