	 	2.	REQUIREMENTS CONTRACT 

 LAYTON BIOSCIENCE agrees to purchase its
requirements for the PRODUCT and ISOMERS exclusively from POLI through INTERCHEM. POLI and INTERCHEM agree to supply the PRODUCT to LAYTON BIOSCIENCE for its exclusive use in marketing pharmaceutical products that are indicated for hypertension,
neurological disorders, or psychiatric disorders, and to supply the PRODUCT to LAYTON BIOSCIENCE for its non-exclusive use in marketing pharmaceutical products indicated for any and all other indications. POLI and INTERCHEM agree to supply the
ISOMERS to LAYTON BIOSCIENCE for its exclusive use in marketing pharmaceutical products indicated for any and all indications. LAYTON BIOSCIENCE acknowledges that POLI and INTERCHEM are cooperating with another company for the use of the PRODUCT to
be combined with another active ingredient in a pharmaceutical product for the indication of smoking cessation, and that this grant of exclusivity in no way impairs the rights of POLI and INTERCHEM to continue such cooperation and to sell the
PRODUCT for use in combination with another active ingredient in a pharmaceutical product for the indication of smoking cessation. POLI and INTERCHEM therefore reserve the right to contract with third parties in order to combine PRODUCT with another
active ingredient and market the resulting pharmaceutical product for the indication of smoking cessation.

 INTERCHEM agrees to supply and fill all orders from LAYTON BIOSCIENCE with PRODUCT and ISOMERS from
PRODUCT and ISOMERS manufactured by POLI upon order from LAYTON BIOSCIENCE except as provided herein or otherwise as agreed to in writing between LAYTON BIOSCIENCE and either of the other two PARTIES. Pursuant to the provisions of this Agreement,
POLI agrees to manufacture a sufficient quantity of the PRODUCT and ISOMERS to meet LAYTON BIOSCIENCE’s requirements for the same. 
  

	 	a.	Volume 

 To assist INTERCHEM and POLI in meeting
their obligations under this contract, LAYTON BIOSCIENCE will provide an annual forecast of its needs for the PRODUCT to INTERCHEM which forecast will be updated at least semi-annually. LAYTON BIOSCIENCE will purchase over the life of this Agreement
the minimum total volume of PRODUCT specified in Exhibit A. In addition, each year LAYTON BIOSCIENCE will purchase the minimum yearly volume of PRODUCT specified in Exhibit A. 
 Upon initiation of scale-up of batches for LAYTON BIOSCIENCE ISOMERS, LAYTON BIOSCIENCE will enter good faith negotiations with POLI and INTERCHEM to
determine minimum total volume requirements for such ISOMERS for the period of time remaining in the term of this Agreement. 
  

 - 4 - 









	 	b.	Orders 

 LAYTON BIOSCIENCE shall place written orders for the
PRODUCT and to the extent applicable, ISOMERS with INTERCHEM at least twelve (12) weeks in advance of the earliest delivery date required hereunder. Each order shall specify the delivery dates and quantity of the PRODUCT and/or ISOMERS ordered.
INTERCHEM shall promptly convey to POLI the quantity of PRODUCT and/or ISOMERS and delivery dates specified in the LAYTON BIOSCIENCE orders. POLI agrees to manufacture and ship to Siegfried CMS Ltd in Zofingen, Switzerland sufficient PRODUCT and/or
ISOMERS in a timely fashion so as to comply with LAYTON BIOSCIENCE’s orders. POLI shall ship PRODUCT and/or ISOMERS in accordance with such orders (provided such orders are within +/- 10% of LAYTON BIOSCIENCE’s forecast for any PRODUCT or
ISOMERS over the twelve (12) month period preceding the order) to Siegfried CMS Ltd F.O.B. in Zofingen, Switzerland. Title and risk of loss shall be POLI and INTERCHEM’s responsibility until delivered to LAYTON BIOSCIENCE or its agent
Siegfried CMS Ltd. in Zofingen, Switzerland. POLI or INTERCHEM may decline to accept orders for any of the PRODUCT or ISOMERS if either POLI or INTERCHEM has received the opinion of patent counsel that the production or sale of the PRODUCT or
ISOMERS would infringe on the patent rights of others in either the United States or the country in which POLI’s manufacturing facility is located. Pursuant to the requirements of Paragraph 3.d. of this Agreement, POLI or INTERCHEM will
promptly notify LAYTON BIOSCIENCE in such a circumstance, and provide LAYTON BIOSCIENCE with a reasonable opportunity to resolve such an issue. 
  

 - 5 - 








 Within thirty (30) days from the date of this Agreement, and at any other time during this
Agreement, POLI will advise if there are any existing patents in the country where POLI’s manufacturing facility is located which would preclude POLI from providing the PRODUCT or ISOMERS to LAYTON BIOSCIENCE and advise as to the first date
when POLI may lawfully supply the PRODUCT or ISOMERS. 
  

	 	c.	Modification of Orders 

 Orders may be modified only
upon six (6) weeks written notice to INTERCHEM. LAYTON BIOSCIENCE agrees to accept and pay for all PRODUCT and ISOMERS scheduled for delivery less than six (6) weeks prior to INTERCHEM’s receipt of such written notice on the terms and
conditions previously agreed to. INTERCHEM shall promptly notify POLI of any such modifications. ill no event may the volume of PRODUCT purchased in any calendar year be less than the yearly minimum specified in Exhibit A. 
  

	 	d.	Acceptance and Rejection 

 If LAYTON BIOSCIENCE
determines that any PRODUCT and/or ISOMERS is defective in material or workmanship, not in conformance with the specifications in Exhibit B or current Good Manufacturing Practices (cGMP) as determined by the United States Food and Drug
Administration (FDA), is adulterated or misbranded, or is otherwise not in conformity with this Agreement (Defective Product), then LAYTON BIOSCIENCE, in addition to any other rights it may have under this Agreement, may reject 

  

 - 6 - 








 
and return any such PRODUCT and/or ISOMERS to POLI and INTERCHEM. At the time of such rejection, LAYTON BIOSCIENCE shall provide INTERCHEM with a written
notice describing in detail the circumstances surrounding the rejection and LAYTON BIOSCIENCE’s reasons therefor. If LAYTON BIOSCIENCE rejects any PRODUCT and/or ISOMERS it will, at POLI and INTERCHEM’s option, either return them to POLI
or INTERCHEM, destroy or dispose of them in the least expensive and most environmentally sound manner, or take other actions as POLI and INTERCHEM may request, within reason. In any event, POLI and INTERCHEM shall be responsible for all costs of any
such return, destruction, disposal, or any other action. 
 LAYTON BIOSCIENCE or its agent shall promptly inspect each shipment of the PRODUCT and/or ISOMERS
and notify INTERCHEM of any deficiencies. It shall be the responsibility of INTERCHEM and POLI to promptly remedy any such deficiency. LAYTON BIOSCIENCE will make available samples of any allegedly defective PRODUCT and ISOMERS and, if requested,
return the same to INTERCHEM at INTERCHEM’s expense by the means specified by INTERCHEM. LAYTON BIOSCIENCE shall be deemed to have accepted a PRODUCT and/or ISOMERS shipment if written notice of any alleged deficiency is not received within
sixty (60) days from delivery to LAYTON BIOSCIENCE or its agent in Zofingen, Switzerland. 
 In the event LAYTON BIOSCIENCE receives
Defective Product from POLI or INTERCHEM, LAYTON BIOSCIENCE may avail itself, but is not limited to, the following remedies: (i) the replacement by POLI and INTERCHEM of rejected PRODUCT and/or ISOMERS that have either been returned or
destroyed with PRODUCT and ISOMERS that are not Defective Product; or (ii) a full refund of any amount paid hereunder by LAYTON BIOSCIENCE for such Defective Product. 
  


 - 7 - 








 If POLI and INTERCHEM replace such Defective Product with PRODUCT and ISOMERS that are not Defective Product within
thirty (30) days from their rejection, there will be no alteration of the minimum total volume of PRODUCT requirement for the life of this Agreement as specified in Exhibit A. If after receiving allegedly defective PRODUCT INTERCHEM/POLI
disagree with LAYTON BIOSCIENCE as to the existence of a defect, then INTERCHEM/POLI shall have the right to investigate the nature and existence of the defect in a commercially reasonable time. If after this time frame a disagreement between the
parties continues to exist then INTERCHEM/POLI will submit the samples to a mutually acceptable independent testing laboratory to test for the alleged defect. Results from the testing laboratory will be binding on both INTERCHEM/POLI, and LAYTON
BIOSCIENCE, and the costs for the independent testing will be borne by the Party against whom the laboratory decides. 
 The minimum total volume of PRODUCT
required under this Agreement as specified in Exhibit A will be reduced if and only if LAYTON BIOSCIENCE is forced, for a legitimate reason, to go to a third-party manufacturer for its PRODUCT or ISOMER needs. A legitimate reason includes four
circumstances: 1) if POLI and INTERCHEM are unable to supply PRODUCT or ISOMERS for any reason; 2) if POLI and INTERCHEM are unwilling to produce the PRODUCT or ISOMERS for any reason; 3) if POLI and INTERCHEM consistently fail to meet regulatory
specifications, including but not limited to U.S. Food and Drug Administration Current Good Manufacturing Practices, and any specifications listed under the terms of this agreement as specified at Exhibit B; or 

  

 - 8 - 








 
4) termination or expiration of this Agreement. LAYTON BIOSCIENCE will determine when and if POLI and INTERCHEM have consistently failed to meet regulatory
and product specifications. If a disagreement arises as to the existence of a consistent failure to meet regulatory specifications, related U.S. Food and Drug Administration action (including but not limited to issuance of Warning Letters or Form
483s) will serve as prima facie evidence thereof. In the absence of U.S. Food and Drug Administration action, the parties will submit the issue to a mutually acceptable third party arbitrator, whose decision will be final in accordance with
Paragraph 26 of this Agreement. The costs of the arbitration will be borne by the party against whom the arbitrator decides. 
  

	 	e.	Term 

 The term of the Agreement is five
(5) years from the date of Food and Drug Administration approval of Product or the effective date of this Agreement, whichever is later. It shall be thereafter automatically extended by a term of one (2) years except any PARTY may provide
written notice at least twelve (12) months prior to the expiration of any term that it does not wish the Agreement to be renewed for an additional one (2) year period. 
  

	 	3.	PATENTS AND PATENT INFRINGEMENT 

  

	 	a.	Validity of PARTIES Patents 

 INTERCHEM and POLI,
both independently and collectively, hereby represent and warrant that pursuant to its manufacturing and supply of PRODUCT and ISOMERS that to the best of their knowledge and belief the Patents they will utilize in the furtherance of the

that these Patents infringe the claims of any third-party patent or other third-party property rights. 
  

	 	b.	Patent and Know-How Rights Gained During Agreement 

 The PARTIES recognize that in the course of work under this Agreement, a PARTY may independently make or otherwise acquire rights to inventions (including without limitation, processes, methods, and improvements to the manufacturing
materials, equipment, procedure, or LAYTON BIOSCIENCE patents or other technology during the term of this Agreement) or know-how useful in the manufacture of PRODUCT or ISOMERS. In such event, the PARTY independently making or acquiring the
invention or know-how shall be the sole owner of that invention or know-how. 
  

 - 10 - 








 With respect to any such inventions or know-how for which POLI or INTERCHEM are the sole owner, POLI
and/or INTERCHEM will grant to LAYTON BIOSCIENCE or any acquiring entity of LAYTON BIOSCIENCE a non-exclusive, royalty-free license, with a right to sublicense, any know-how and patents or patent applications for such inventions under four
circumstances: 1) if POLI and INTERCHEM are unable to produce the PRODUCT or ISOMERS for any reason; 2) if POLI and INTERCHEM are unwilling to produce the PRODUCT or ISOMERS for any reason; 3) if POLI and INTERCHEM consistently fail to meet
regulatory and product specifications, including but not limited to U.S. Food and Drug Administration Current Good Manufacturing Practices, and any specifications listed under the terms of this agreement at Exhibit B; or 4) termination or expiration
of this Agreement. LAYTON BIOSCIENCE will determine in its sole discretion when and if POLI and INTERCHEM have consistently failed to meet regulatory and product specifications. If a disagreement arises as to the existence of a consistent failure to
meet regulatory specifications, related U.S. Food and Drug Administration action (including but not limited to issuance of Warning Letters or Form 483s) will serve as prima facie evidence thereof. In the absence of U.S. Food and Drug Administration
action, the parties will submit the issue to a mutually acceptable third party arbitrator, whose decision will be final in accordance with Paragraph 26 of this Agreement. The costs of the arbitration will be borne by the party against whom the
arbitrator decides. 
 To the extent that LAYTON BIOSCIENCE or any acquiring entity of LAYTON BIOSCIENCE sublicenses any POLI or INTERCHEM
inventions or know-how under these provisions, the licensees of such sublicenses are limited to entities manufacturing pharmaceutical products on behalf of LAYTON BIOSCIENCE or any acquiring entity of LAYTON BIOSCIENCE, and any such sublicenses must
state that the use of the POLI or INTERCHEM inventions or know-how are limited to manufacturing pharmaceutical products for the direct benefit of LAYTON BIOSCIENCE or any acquiring entity of LAYTON BIOSCIENCE. 
  

 - 11 - 








 With respect to any inventions that are jointly made by the PARTIES (i.e., inventions in which one or more
inventors from each PARTY have made an inventive contribution as determined by the laws of inventorship), including any inventions made by a PARTY’s employee or third-party contractor obliged to assign such invention to a PARTY, concerning
PRODUCT or ISOMERS or processes or methods relating to PRODUCT or ISOMERS, the PARTIES shall own such inventions (and any patent applications filed on such inventions and any patents issued on such inventions) jointly as co-owners of equal,
undivided shares without right of accounting for any act carried out in accordance with the invention, and agree to cooperate and assist one another in filing any patent applications and undertaking all other reasonable and appropriate protection
for such patentable joint inventions, including provision of powers of attorney for this purpose. 
 If any proceedings in bankruptcy or in
reorganization, or for the appointment of a receiver or trustee for all or a substantial portion for the assets of any PARTY to this Agreement, or any other like proceedings, under any law for the relief of debtors shall be instituted by or against
any PARTY hereto and are not dismissed within ninety (90) days, any patent or know-how rights gained during this Agreement shall pass to the successors in interest to the PARTIES. 
  

 - 12 - 









	 	c.	Prosecution of Joint Patents 

 LAYTON BIOSCIENCE shall have the
first right, but no obligation, to undertake joint patent filings and prosecution in one or more countries respecting jointly held inventions, subject to reimbursement from POLI and INTERCHEM for one-half of any reasonable out-of-pocket expenses
LAYTON BIOSCIENCE incurs in such filing and prosecution. In the event LAYTON BIOSCIENCE fails to undertake the filing of such a patent application within ninety (90) days of a notice by LAYTON BIOSCIENCE to POLI or INTERCHEM that it believes
the filing of such an application is appropriate, POLI and INTERCHEM may undertake such a filing at their own expense, in which event any subsequently issued patent application shall be owned solely by POLI or INTERCHEM. A PARTY may not assign its
rights to any jointly owned invention, application or subsequently issued patent except on the written approval of the other PARTIES to this Agreement, which approval shall not be unreasonably withheld. 
  

	 	d.	Patent Infringement and Third-Party Claims 

 Upon
the occurrence of any infringement or suspected or threatened infringement of any PARTY’s patents, or misappropriation or misuse of the know-how or confidential information related to such patents, any knowledgeable PARTY shall as soon as
practicable consult with the remaining PARTIES to determine what steps should be taken to prevent or terminate such infringement. 
  

 - 13 - 








 If a third-party asserts that a patent or other right owned by it is infringed by the manufacture of
PRODUCT or ISOMERS by POLI or INTERCHEM pursuant to this Agreement, the PARTY first obtaining knowledge of such a claim shall immediately provide the other PARTIES notice of such claim and the related facts in reasonable detail. Each PARTY agrees to
investigate the situation fully in collaboration with the other two PARTIES, and the PARTIES agree to discuss how best to control the defense of any such claim. In the event the PARTIES cannot agree on the defense of any such claim, LAYTON
BIOSCIENCE shall have the right, but not the obligation, to control such defense. POLI and INTERCHEM shall have the right to be represented separately by counsel of its own choice. 
 As to the enforcement of jointly owned patents, including actions against an infringer, the PARTIES shall consult with each other in good faith as to the
best manner in which to proceed. The PARTIES agree as a basic principle that in the case of such actions against infringers, the expenses incurred and damages awarded shall be for the account of the PARTY or PARTIES undertaking such actions to the
extent of their financial participation therein. 
 For the duration of this Agreement, and for any subsequent term of the same, LAYTON
BIOSCIENCE hereby agrees not take any patent infringement or other like action against POLI and INTERCHEM related to their manufacture and supply of ISOMERS that are the subject of patents issued to LAYTON BIOSCIENCE. 
 For the duration of this Agreement and any subsequent term of the same, and pursuant to grants of POLI and/or INTERCHEM licenses for know-how or patents
under the terms of this Agreement, POLI and INTERCHEM hereby agree not to take any patent infringement or other like action against LAYTON BIOSCIENCE or LAYTON BIOSCIENCE’s agents related to LAYTON BIOSCIENCE’s or its agents testing,

	 	a.	Changes in Process 

 POLI reserves the right to
modify or change the process by which it manufactures the PRODUCT or ISOMERS. POLI will not manufacture PRODUCT or ISOMERS prepared by any such modified or changed process until it has notified LAYTON BIOSCIENCE and LAYTON BIOSCIENCE, POLI, and
INTERCHEM have received all necessary regulatory approvals. POLI further agrees to provide documentation concerning processing changes to the PRODUCT and ISOMERS and samples thereof produced by any such modified or changed process to LAYTON
BIOSCIENCE within thirty (30) days of their first production so that LAYTON BIOSCIENCE may verify that the PRODUCT and/or ISOMERS meets or exceeds all applicable quality standards. 
  

 - 18 - 









	 	6.	RECALL, WITHDRAWAL, OR FIELD CORRECTION 

 If LAYTON BIOSCIENCE
initiates or is required to initiate a product recall, withdrawal, or field correction with respect to, or if there is any governmental seizure of, any of its products containing any PRODUCT or ISOMERS supplied hereunder which action is due, in
whole or in part to the negligent or intentional wrongful act or omission of POLI or INTERCHEM in connection with the testing, manufacturing, release and control of PRODUCT or ISOMERS hereunder, LAYTON BIOSCIENCE will notify INTERCHEM or POLI
promptly of the details regarding such action, including providing copies of all relevant documentation concerning such action. POLI and INTERCHEM will assist LAYTON BIOSCIENCE in investigating any such situation and all regulatory contacts and
communications that are made and all activities concerning seizure, recall, withdrawal, or field correction will be jointly coordinated by LAYTON BIOSCIENCE, POLI, and, INTERCHEM, although the final decisions with respect to seizure, recall,
withdrawal, field correction or regulatory contacts and communications will be with LAYTON BIOSCIENCE. 
 If any such recall, withdrawal,
field correction, or seizure occurs due solely to the negligent or intentional wrongful act or omission of POLI or INTERCHEM in connection with the testing, manufacturing, release and control of PRODUCT or ISOMERS hereunder, then POLI and INTERCHEM
shall bear the full cost and expense including reasonable attorney=s and consultant=s fees, of any such seizure, recall, withdrawal, or field correction. If any such recall, withdrawal, field correction, or seizure occurs due solely to the negligent
or intentional wrongful act or omission of LAYTON BIOSCIENCE, including LAYTON BIOSCIENCE’s failure to properly ascertain whether PRODUCT or ISOMERS meets regulatory and product specifications, then LAYTON BIOSCIENCE shall bear the full cost
and expense of any such seizure, recall, withdrawal, or field correction. If more than one of the PARTIES contributes to the cause of a seizure, recall, withdrawal, or field correction, the cost and expenses thereof will be shared in proportion to
each PARTY’s contribution to the problem. 
  

 - 19 - 








 If any such recall, withdrawal, field correction, or seizure occurs due to a latent defect in the Product
(i.e., a defect other than the failure of the product to meet the established specifications in Exhibit B for the PRODUCT or similar specifications established for ISOMERS), as delivered to LAYTON BIOSCIENCE, that affects its quality or
functionality, then POLI/INTERCHEM and LAYTON shall equally share the cost and expense of any such seizure, recall, withdrawal, or field correction. 
  

	 	7.	FORCE MAJEURE 

 Neither INTERCHEM, POLI, nor LAYTON
BIOSCIENCE shall be liable or be in breach of any existing provision hereof for delays in delivery or failure to manufacture and deliver to the extent such delays are due to an event of force majeure; including: (1) causes beyond its reasonable
control, (2) acts of God, acts of civil or military authority, government controls or regulations, fire, strikes, accidents, floods, epidemics, quarantine restrictions, war, or (3) inability to obtain necessary labor, materials, components
or manufacturing facilities through regular channels due to causes beyond its reasonable control and only if the PARTY affected shall have used all reasonable efforts to avoid such occurrence and to remedy it promptly if it shall have occurred. In
the event of any such delay that impacts the performance of POLI or INTERCHEM under this Agreement, the date of delivery of PRODUCT or ISOMERS shall be deferred to a period up to but not to exceed the time attributable to the delay. If an event of
force majeure causes a failure or delay by POLI or INTERCHEM that exceeds forty-five (45) days, LAYTON BIOSCIENCE may, at its sole discretion, elect to obtain the PRODUCT or ISOMERS from another source for such period of time as such delay
continues. 
  

 - 20 - 








 In the event that an act of force majeure causes a failure in the manufacture or delay in the delivery of
PRODUCT or ISOMERS, once the direct effects of such an event are no longer present, POLI and INTERCHEM shall place priority on the manufacturing and supply of the deferred PRODUCT or ISOMERS for LAYTON BIOSCIENCE to the exclusion of all other
manufacturing and supply activities. 
 If there is a failure in the manufacture or delay in the delivery of PRODUCT due to an event of force
majeure, and the delivery of PRODUCT or ISOMERS is deferred by less than forty-five (45) days, there will be no alteration of the minimum total volume of PRODUCT requirement for the life of this Agreement as specified in Exhibit A, and any
minimum total volume requirement for ISOMERS as agreed upon by the PARTIES. However, if an event of force majeure causes the delivery of PRODUCT or ISOMERS to be deferred by more than forty-five (45) days, and such a deferral occurs within the
last sixty (60) days within a given yearly period as specified in Exhibit A, or any applicable twelve (12) month period per an agreed upon schedule for minimum total volume requirements for ISOMERS, the volume of PRODUCT or ISOMERS related
to such a deferral shall be deducted from the yearly minimum total volume of PRODUCT requirement for the year in which the deferral occurred pursuant to the schedule in Exhibit A or any applicable twelve (12) month period per an agreed upon
schedule for minimum total volume requirements for ISOMERS. 
  

 - 21 - 








 In the event that an act of force majeure causes a failure in the delay in the delivery of PRODUCT or
ISOMERS that exceeds ninety (90) days, LAYTON BIOSCIENCE may terminate this Agreement at its sole discretion, and in such a circumstance shall not be responsible for meeting any and all of the minimum volume of PRODUCT or ISOMERS requirements
as specified in Paragraph 2.a. and Exhibit A of this Agreement, or otherwise agreed upon by the PARTIES for ISOMERS. 
 Pursuant to the
PARTIES good faith negotiations concerning minimum total volume requirements as discussed in Paragraph 2.a. of this Agreement, the PARTIES will specifically delineate the effects of an event of force majeure effecting the delivery of ISOMERS to
LAYTON BIOSCIENCE on such minimum total volume requirements. 
  

	 	8.	INTELLECTUAL PROPERTY AND TECHNOLOGY TRANSFER 

  

	 	a.	Grants and Licenses 

 LAYTON BIOSCIENCE hereby
grants POLI and INTERCHEM a non-exclusive license without right to sublicense under the LAYTON BIOSCIENCE Patents for ISOMERS for the sole purpose of manufacturing the ISOMERS during the term of this Agreement. This license may not be assigned or
transferred without the prior written consent of LAYTON BIOSCIENCE. 
 POLI and/or INTERCHEM will hereby grant to LAYTON BIOSCIENCE or any
acquiring entity of LAYTON BIOSCIENCE a non-exclusive, royalty-free license, with a right to sublicense, any know-how, Patents, or Patent applications for manufacturing or processing PRODUCT or ISOMERS, under four circumstances: 1) if POLI and
