a) Company shall use Commercially Reasonable Efforts to develop, prepare and submit for approval an NDA with the FDA and perform all related development activities up to and including receiving NDA Approval in conformity in all material respects with all applicable federal, state and local laws, regulations, orders and ordinances pertinent thereto.

Company will be responsible for manufacturing of the Product submission batches and satisfactory submission thereof to the FDA for the NDA submission. For the avoidance of doubt, Company shall be the sole owner of KP201, the Product, and the NDA and shall be responsible for managing the regulatory approval process with respect to the NDA, including handling all quality assurance decisions with respect to approving the Product for commercial sale, recalls and all other product compliance issues with respect to the Product. With respect to KP201, the Product, and any inventions which Company solely owns, Company shall be the sole owner of, and solely responsible for the preparation, filing, prosecution and maintenance of, any and all existing and/or hereinafter filed or issued patents, including continuations and substitute applications thereof, and all foreign counterparts thereof, at Company’s sole expense.

Company shall keep JMI informed of the progress of the prosecution of the NDA. Upon receipt of written or oral communications from the FDA or any other regulatory authority relating to the Product and the Product’s NDA, Company shall notify JMI and provide a copy of any written communication as requested as soon as reasonably practicable but in no case more than fourteen (14) business days from the receipt thereof.

b) Subject to JMI receiving the necessary DEA quota, JMI shall use Commercially Reasonable Efforts to provide the following development services:


Phase 1:		JMI will deliver to Company [] each of API in [] forms, to be reasonably determined by Company;

Phase 2:		Upon Company’s selection and written notification to JMI of the desired [*] form of the API, JMI will scale and optimize the process for commercial production; and

Phase 3:		Upon completion of Phase 2, JMI will prepare and ship to Company [] of cGMP API in the [] form selected during Phase 2. The parties anticipate the shipment of such [] cGMP API will be approximately [] from the Effective Date, but in no event shall such shipment be earlier than [] from the date on which Company notifies JMI of the selected [] form of the API in Phase 2.

c) In consideration of the development work provided by JMI pursuant to Article 2(b), and the provision of research and development quantities of API to Company by JMI hereunder, Company shall issue to JMI 564,516 shares of the Company’s Class A common stock (the “Company Shares”) upon completion of Phase 3 as defined in Section 2(b). The determination of the Company’s Shares is based on the investment described in the first sentence of this Section 2(c) having a value of $[*] at a per share price of $[*]. Prior to the Company’s issuance of the Company Shares to JMI, JMI shall execute a subscription agreement substantially in the form attached hereto as Exhibit C.

d) JMI shall use Commercially Reasonable Efforts to develop reference standards, impurities, applicable validated analytical methods, and stability profiles for the API in conformity in all material respects with all applicable federal, state and local laws, regulations orders and ordinances pertinent thereto.

e) JMI shall prepare and submit to the FDA the DMF and maintain, amend, update and supplement such DMF as required by the FDA in order for an NDA which incorporates the DMF by reference to receive NDA Approval. During the Term JMI shall grant to Company exclusive access to the DMF for reference in connection with Company’s NDA, and JMI shall file with the FDA such written authorizations as may be reasonably necessary in order to permit such access.

f) Subject to receiving the necessary DEA quotas, the parties will endeavor to meet the NDA development timelines provided in Exhibit A.

g) JMI shall use Commercially Reasonable Efforts to support Company’s preparation, filing, prosecution and maintenance of the NDA.

h) Upon receiving NDA Approval, Company shall use Commercially Reasonable Efforts in its Commercial Launch of the Product in accordance with all specifications set forth in the regulatory filings applicable to the Product.

ARTICLE 3. Purchase and Sale of API

a) During the Term Company agrees to purchase from JMI one hundred percent (100%) of Company’s requirements of the API for the Product in the Territory, subject to the provision of Section 3(h), and JMI shall satisfy such requirements by selling directly to Company such API in accordance with the forecasting provisions in Section 3(b). JMI shall not supply any third party in the Territory with API during the Term.

b) Unless otherwise mutually agreed in writing, at least [*] in advance of Company’s Commercial Launch hereunder, Company shall provide JMI with a [*] month estimate, by Calendar Quarter, of its requirements of such API. [*] days prior to the start of each Calendar Quarter (the “Firm Quarter”), the forecast for such quarter shall become a binding order, which, for record purposes only, Company shall provide JMI with a purchase order. Prior to the aforementioned [*] day, Company may modify its forecast for a Firm Quarter by no more than [*] from the last estimate for such Firm Quarter unless otherwise mutually agreed upon by both parties by providing written notice of such modification to JMI. Moreover, at least [*] days in advance of the Firm Quarter, Company shall update its estimates for the [*] Calendar Quarters succeeding the Firm Quarter and JMI shall be entitled to rely on the forecast for the [*] in such rolling forecast for the purpose of obtaining the necessary raw materials for the manufacture of such API.

For example and for illustration purposes only, if Company desires that Commercial Launch of Product begins on [*], Company shall provide to JMI no later than [*], a forecast of the quantities required for the calendar quarters beginning on [*]. On [*], the forecast for the quarter beginning on [*] (the Firm Quarter in this example), will become a binding order, and Company will provide JMI with an updated forecast of the quantities required for the calendar quarters beginning on [*].

Additionally, Company will provide JMI with DEA-222 and Certificate of Available Quota forms in proportion to such forecasts not less than ten (10) days prior to any requested delivery date. If so requested by Company and subject to Article 5, JMI will use Commercially Reasonable Efforts to supply Company with API in excess of any estimates or forecasts, provided that failure to provide such excess amounts shall not be deemed to be a breach of this Agreement.

c) For the initial order of API to be used for commercial sale of the Product, the parties will agree on the forecast, including shipment schedules, at the earliest practicable time and JMI will use Commercially Reasonable Efforts to supply such API as specified in that order. Batch sizes for lots to be used for submission in Company’s NDA will be defined by the Company, subject to JMI’s agreement, during the validation process, but shall not be less than one-half of the entire batch size required for the completion of the validation process.

d) API shall be shipped FOB JMI’s West Deptford plant, packed in accordance with DEA and United States Department of Transportation requirements for interstate shipment. JMI shall ship the quantity of API ordered by Company in accordance with the delivery instructions set forth in each purchase order and mutually agreed prior to shipment. In the event Company is unable for any reason to supply the necessary DEA Certificate of Available Quota form prior to the requested delivery date, Company shall pay for such Product which will be held by JMI at Company’s risk of loss pending receipt of the appropriate Quota form from Company.

e) Excepting quantity orders, the terms and conditions contained in any purchase order, acknowledgment and invoice issued by either party in connection with this Agreement shall be void and of no effect.

f) JMI shall produce API in conformance with the applicable API Specifications set forth at Exhibit B. If the FDA modifies the API Specifications as a condition for obtaining NDA Approval and Company so notifies JMI in writing, JMI shall use Commercially Reasonable Efforts to perform its obligations under this Agreement at no additional cost to Company; provided that in the event that the Specifications are changed in a manner that results in increased costs to JMI, the parties shall negotiate in good faith a price increase to be reflected in the API Manufacturing Cost that is commensurate with the cost increase.

g) Except with respect to JMI’s responsibility in connection with the DMF as provided in Section 2(e), Company shall be responsible for all regulatory and commercial activities related to Product, including without limitation, performing quality assurance testing and stability testing, maintaining adverse drug information, complaints and annual reports, so that the Product conforms to all applicable federal, state and local laws, regulations orders and ordinances.

h) Upon Commercial Launch of the Product, JMI shall identify and qualify an alternative site of JMI or its Affiliates to serve as a secondary supplier of API, subject to the approval of Company, which approval shall not be unreasonably withheld. In the event JMI is unable to qualify a secondary supplier, Company may qualify a secondary supplier to provide no greater than [*] of the API for each Calendar Year; provided, however, that in the event JMI is unable to satisfy Company’s requirements, then: (i) Company may purchase from such secondary supplier [*], and (ii) JMI shall [*], if any, [*] the secondary supplier [*] so long as JMI consents to the [*] such secondary supplier, which consent shall not be unreasonably withheld, and Company does not include the [*] in the calculation of [*] for purposes of calculating the [*]. For the avoidance of doubt, all [*] calculations will be based on [*] and will be [*].

ARTICLE 4. Price and Payment

a) Royalty: During the Term Company will pay JMI a royalty on Net Profits. The total royalty shall be calculated as the Minimum Royalty (defined below) plus the Additional Royalty (defined below). The Minimum Royalty and Additional Royalty are collectively referred to as the “Royalty” or “Royalties”.

i) Minimum Royalty: JMI will provide Company, free of charge, any API which is delivered for use prior to the completion of the Product’s validation process. In consideration thereof, during the Term, Company shall pay JMI a minimum royalty on the Net Profits of the Product sold in each Calendar Quarter in accordance with the following tiered royalty rate based on the Gross Sales of the Product for such Calendar Year (“Annual Gross Sales”) (the foregoing royalty hereinafter the “Minimum Royalty”):


Annual Gross Sales (in USD) of the Product	Royalty Rate on Net Profits
For the First $[*]		[	*]%

From Greater than $[] up to and including $[]		[	*]%

From $[] to $[]		[	*]%

From $[*] or greater		[	*]%

For clarification and illustration purposes only, calculation of Minimum Royalty will be based on the following examples: the Minimum Royalty rate on Net Profits will be [*]% until cumulative sales reach $[*] USD after which time the Minimum Royalty rate will fall to the second tier i.e. [*]%; for example if the Gross Sales of the Product in the first three months of a Calendar Year were $[*], $[*], and $[*] respectively, the Minimum Royalty would be calculated as [*]% of Net Profits from the first $[*] of Annual Gross Sales plus [*]% of Net Profits from the next $[*] in Annual Gross Sales. If the cumulative Net Profit in any Calendar Quarter is a negative figure (a “Net Loss”), then for purposes of calculating the Minimum Royalty, such Net Loss shall be carried forward and offset against a subsequent Calendar Quarter’s Net Profit; provided, however, that a Net Loss for any given Calendar Quarter cannot be carried forward beyond the [*] immediately following consecutive Calendar Quarters for purposes of calculating the Minimum Royalty for the subsequent Calendar Quarters.

ii) Additional Royalty: Subject to Section 4(a)(iii), JMI will provide Company, free of charge, any API which is delivered during the period of time occurring immediately after the completion of the validation process and continuing until API is delivered for use in Company’s Commercial Launch. In consideration thereof, notwithstanding payment of the Minimum Royalty, Company shall pay JMI an additional royalty on the Net Profits of the Product sold in each Calendar Quarter in accordance with the following tiered royalty rate based on the Annual Gross Sales of the Product in such Calendar Year (“Additional Royalty”):


Annual Gross Sales (in USD) of the Product	Royalty Rate on Net Profits
For the First $[*]		[	*]%

From Greater than $[] up to and including $[]		[	*]%

From $[*] or greater		[	*]%

For clarification and illustration purposes only, calculation of Additional Royalty will be based on the following examples: the Additional Royalty rate on the Net Profits will be [*]% until cumulative sales reach $[*] USD after which time the Additional Royalty rate will fall to the second tier i.e. [*]%; for example if the Annual Gross Sales of the Product in the first three months of a Calendar Year were $[*], $[*] and $[*], respectively, the Additional Royalty would be calculated as [*]% of Net Profits from the first $[*] of Annual Gross Sales plus [*]% of Net Profits from the next $[*] in Annual Gross Sales. For purposes of calculating the Additional Royalty, a Net Loss during any Calendar Quarter shall be carried forward and offset against a subsequent Calendar Quarter’s Net Profit; provided, however, that a Net Loss for any given Calendar Quarter cannot be carried forward beyond the [*] immediately following consecutive Calendar Quarters for purposes of calculating the Additional Royalty for the subsequent Calendar Quarters.

(iii) After the completion of the validation process relating to the API, JMI and Company may negotiate and agree, in the form of a written addendum to the Agreement, upon a price per unit which Company shall pay JMI, in lieu of the Additional Royalty, for any API which is delivered during the period of time occurring immediately after the completion of the validation process and continuing until API is delivered for use in Company’s Commercial Launch. If the parties so agree, Company will pay the agreed price per unit for such API and will not pay the Additional Royalty to JMI. If the parties cannot agree on such a price per unit of API, JMI will supply such API to Company free of charge and Company will pay Additional Royalty to JMI, pursuant to Section 4(a)(ii). Nothing in this Section 4(a)(iii) affects the required payment of the Minimum Royalty pursuant to Section 4(a)(i).

iv) Sales by Company to its Affiliates shall be made and, for purposes of the calculation of Annual Gross Sales and Net Profits, shall be deemed third party transactions and shall be deemed to have been made, if not actually made, at the price Company would have charged an unaffiliated buyer in an arm’s length transaction of similar size and scope.

b) Price of API for Commercial Use by Company. Beginning with API delivered for use in Company’s Commercial Launch and continuing until the expiration or termination of the Initial Term and Renewal Terms, if any, JMI will supply API for a price equal to the API Manufacturing Cost, subject to the following: The parties hereto acknowledge and agree that as of the Effective Date, JMI is unable to establish the API Manufacturing Cost. Therefore, the parties agree that after the completion of the Product’s validation process and as soon as Commercially Reasonable Efforts permit, JMI will begin to compute the API Manufacturing Cost. Any Calendar Year-to-year increase in the API Manufacturing Cost in excess of the applicable PPI shall require the good faith negotiation and mutual agreement of the parties. JMI shall maintain true and accurate records, files and books of account containing all data reasonably required for the full computation and verification of the API Manufacturing Cost for each Calendar Quarter during the term of the Agreement. Such books and records shall be in accordance with GAAP consistently applied and shall be kept separate from records, files and books of account not pertaining solely to the API. JMI shall permit Company, or at JMI’s option, a mutually agreed independent auditor, at Company’s expense, to independently audit the API Manufacturing Cost.

c) Company shall pay all invoices from JMI for API pursuant to Sections 4(a)(iii) and 4(b) in full within [*] days after the date of the invoice in the form of a wire, check or money order. Company shall pay JMI any Royalties due under Section 4(a) within [*] days after the end of each Calendar Quarter in which Product is sold by Company and Net Profits resulting from such sales are greater than zero in the form of wire, check or money order (or other method of payment approved by JMI in writing). Company will make and retain for a period of [*] years following the termination of this Agreement true and accurate records, files and books of account containing all the data reasonably required for the full computation and verification of Net Profits and Royalties on the Product for each Calendar Year occurring during the term of the Agreement. Such books and records shall be maintained in accordance

with GAAP consistently applied and shall be kept separate from records, files and books of account not pertaining solely to the Product. Company shall permit JMI or, at Company’s option, a mutually agreed independent auditor, at JMI’s cost and expense, to inspect relevant books and records during regular business hours upon not less that fourteen (14) business days written notice.

d) A charge of [*] per month, or the maximum amount permitted by law, whichever is less, shall be due on any amounts due under Section 4(b) which are more than [*] days past due. Company shall be responsible for any duty, sales, use, excise or other tax applicable (except income taxes) to the sales of API by JMI to Company.

ARTICLE 5. DEA Quota and Supply Conditions

a) The parties expect that both the Product and the API will be scheduled under the Federal Controlled Substances Act. JMI and Company are required to obtain a quota from the DEA before producing the Product or the API. Such quotas are limited; therefore, each of the parties shall use its Commercially Reasonable Efforts to obtain DEA quotas for the Firm Quarter requested by Company, and to cooperate with the other party to obtain sufficient quotas.

b) Each party’s obligation hereunder is subject to obtaining the necessary DEA quota. Except as provided in Section 3(f), neither party shall be liable to the other for that quantity of Product or API which the other party is unable to supply or take as a result of failure to obtain a DEA quota, provided that each party has used Commercially Reasonable Efforts to obtain sufficient DEA quota.

ARTICLE 6. Term

a) This Agreement shall become effective as of the Effective Date and shall continue in force i) in the event Company obtains a valid and enforceable patent relating to KP201 and/or the API, until the later of the earliest date on which all of the Company’s rights in all such patents have expired or the tenth (10^th) anniversary of the date on which the Commercial Launch occurs, or ii) in the event the Company does not obtain a valid and enforceable patent on KP201 or the API, for a period of five (5) years following Commercial Launch of the Product (in either case of (i) or (ii) being applicable, the “Initial Term”). Upon the expiration of the Initial Term, this Agreement shall automatically continue in force thereafter for subsequent renewal periods of two (2) years (“Renewal Terms”) unless and until terminated at the expiration of the Initial Term or any Renewal Term by either party providing not less than twelve (12) months written notice prior to the expiration of the Initial Term or any Renewal Term, as the case may be.

b) Notwithstanding the foregoing, the Term shall terminate upon the unanimous written consent of the parties.

c) In the event of a material breach of this Agreement by a party and subject to Article 13, the other party shall have the right to deliver a written notice of breach to the defaulting party. If such breach is not cured within [*] days after delivery of such notice, the nondefaulting party, at its sole option, may terminate the term of this Agreement at any time by delivery of written notice of termination to the defaulting party; provided, however, if the breach cannot reasonably be cured despite Commercially Reasonable Efforts within a [*] day period, then the cure period shall be extended for no more than an additional [*] day period, provided the defaulting party continues to make Commercially Reasonable Efforts to cure the breach.

d) In the event that a party shall (i) voluntarily commence any proceeding or file any petition seeking relief under any Federal, state or local bankruptcy, insolvency, liquidation, receivership

or similar law (a “Bankruptcy Law”), (ii) consent to the institution of, or fail to contravene in a timely and appropriate manner, any such proceeding or the filing of any such petition, (iii) apply for or consent to the appointment of a receiver, trustee, custodian, sequestrator or similar official for such party or for a substantial part of its property or assets, (iv) file an answer admitting the material allegations of a petition filed against it in any such proceeding or (v) make a general assignment for the benefit of creditors, the other party, at its sole option, may terminate the Term at any time by delivery of written notice of termination to the party subject to such event.

e) In the event that a party shall be subject to the commencement of any involuntary proceeding or the filing of any involuntary petition in a court of competent jurisdiction seeking (i) relief in respect of such party or of a substantial part of its property or assets under any Bankruptcy Law, (ii) the appointment of a receiver, trustee, custodian, sequestrator, or similar official for such party or for a substantial part of its property or assets or (iii) the winding-up or liquidation of such party, and such proceeding or petition shall continue undismissed for [*] days or an order or decree approving or ordering any of the foregoing shall continue unstayed and in effect for [*] days, the other party, at its sole option, may terminate the Term at any time by delivery of written notice of termination to the party subject to such event.

f) Termination for default or breach hereunder or for any other reason shall have no effect on performance obligations or amounts to be paid which have accrued up to the effective date of such termination. Articles 8, 9, 10, 11 and 15, Section 2(c), and this Section 6(f) shall indefinitely survive the expiration or other termination of this Agreement.

ARTICLE 7. Assignment or Transfer of Interest

Neither party shall directly or indirectly sell, assign or transfer any part or all of its interest in this Agreement without the prior written consent of the other party, which consent shall not be unreasonably withheld; provided, however, that a change in control of a party shall not be deemed to constitute a transfer of such party’s interest. Notwithstanding the foregoing, JMI may, with the prior approval of Company, transfer its interest to an Affiliate of JMI if such Affiliate is a qualified manufacturer. Subject to the first sentence of this Article 7, in the event Company sells or transfers its NDA to the Product, this Agreement shall also be assigned to the purchaser or transferee and become an obligation of the subsequent NDA holder.

ARTICLE 8. Confidentiality

The parties hereto agree that their obligations to maintain the confidentiality of the Confidential Information shall be not less than the obligations described in the Confidentiality Agreement by and among JMI and Company dated November 28, 2009, a copy of which is attached hereto as Exhibit D, notwithstanding that such agreement may have been terminated prior to the termination of the confidentiality obligations under this Agreement. The confidentiality obligations under this Agreement shall remain in full force and effect during the Term and shall continue for [*] years beyond the expiration or termination of this Agreement.

a) JMI warrants that the API supplied to Company hereunder will conform at the time of shipment from JMI’s West Deptford, New Jersey plant to the specifications described in Exhibit B attached hereto (the “API Specifications”), as the API Specifications may from time-to-time be amended by mutual written agreement or as required by the FDA, other governmental body in the United States or the then current edition of the U.S. Pharmacopoeia.

10.

b) JMI warrants to Company that JMI has not caused, as of the date of each shipment hereunder of any articles subject to the provision of the Act, such article, when shipped from JMI’s West Deptford, New Jersey plant, to be adulterated or misbranded within the meaning of the Act or of any applicable state law in which the definitions of adulteration and misbranding are substantially the same as those contained in the Act, or an article that may not, under the provision of Sections 404, 505, or 512 of the Act, be introduced into interstate commerce. Except as expressly stated in paragraphs a) and b) of this Article 9, JMI MAKES NO OTHER REPRESENTATION OR WARRANTY OF ANY KIND, EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY AS TO MERCHANTABILITY, FITNESS FOR PARTICULAR PURPOSE, OR ANY OTHER MATTER WITH RESPECT TO THE API WHETHER USED ALONE OR IN COMBINATION WITH OTHER SUBSTANCES.

c) JMI will provide Company together with each invoice the results of all assays required to be run under the API Specifications. Any shipment of API will be deemed accepted by Company no later than [*] days after receipt by Company or its designee of the API. If such shipment of API does not comply with the API Specifications, has been damaged prior to being provided to the carrier for shipment, or if there is a shortage in the quantity prior to being provided to the carrier for shipment, Company shall promptly notify JMI in writing, but, in any event, not later than [*] days after receipt. Company or its designee shall promptly return such API to JMI at JMI’s expense, or Company shall undertake such other response as is mutually agreed upon in writing by the parties. JMI shall have the right, but not the obligation, to retest the rejected API within [*] days after its return from Company. In the event that JMI disputes Company’s determination that API does not meet the API Specifications or has been damaged or is subject to a shortage in quantity, the parties shall meet to resolve, in good faith, such dispute; provided that written notice by JMI to Company of any such dispute must be made no later than [*] days after Company’s return of the API.

d) Upon return of any rejected API, and JMI’s agreement, or a final determination in accordance with this Agreement, that such API fails to comply with JMI’s limited warranty or has been damaged, JMI will replace the API at JMI’s cost and will resubmit to Company within [*] days of receipt of additional raw materials. COMPANY’S EXCLUSIVE REMEDY FOR BREACH OF WARRANTY SHALL BE DIRECT DAMAGES, AND JMI’s LIABILITY TO COMPANY FOR ANY AND ALL LOSSES OR DAMAGE FROM ANY CAUSE WHATSOEVER, INCLUDING, WITHOUT LIMITATION, ALLEGED NEGLIGENCE, SHALL IN NO EVENT EXCEED THIS OBLIGATION TO REPLACE THE API AND RESUBMIT IT TO COMPANY, OR IN THE EVENT THAT JMI FAILS TO REPLACE THE API, THEN TO [*] FOR THE [*] A SECONDARY SUPPLIER; provided that JMI’s obligation to [*] for the [*] a secondary supplier is subject to the following conditions: (x) JMI consents to the [*] such secondary supplier, which consent shall not be unreasonably withheld, and (y) Company shall not include the [*] in the calculation of [*] for purposes of calculating the [*]. For the avoidance of doubt, all [*] calculations will be based on [*] and will be [*]. Notwithstanding the forgoing, if Company rejects three or more API shipments during any [*] consecutive month period, and JMI agrees, or a final determination is made, that each such shipment failed to comply with JMI’s limited warranty under this Article 9, then Company may find JMI to be in material breach and exercise its right under Section 6(c) to terminate the Agreement.
