subject to availability of Manufacturing Quota and Procurement Quota.  The calculation of the minimum annual volume of API shall include the Finished Good Tapentadol as calculated in accordance with Appendix D.  [***].

1.2.                            During the Transition Period, such API is for use in the qualification and validation of Purchaser’s facility for the manufacture of Products, clinical and non-clinical development of Products, or analytical testing or analytical development of Products (such use “Non-Commercial Use”).  Purchaser shall not use any API supplied by Noramco during the Transition Period for any purpose other than Non-Commercial Use without Noramco’s prior written consent.

1.3.                            After the Transition Period, such API is for use in the manufacture of Products for commercial distribution in the United States (such use “Commercial Use”).  Purchaser shall not use any API supplied by Noramco for any purpose other than Commercial Use or Non-Commercial Use without Noramco’s prior written consent.

1.4.                            Noramco shall use [***] efforts to supply Purchaser with API in the quantities and on the date(s) specified in each Purchaser purchase order. Noramco will use [***] efforts to supply Purchaser with impurity reference standards related to API at a [***] cost, with such impurity reference standards to be used only to support Purchaser’s analytical testing.

1.5.                            Purchaser will keep accurate records of its requirements of API during the Term, and, upon the request of Noramco, will permit Noramco or its duly authorized agents to examine such records during normal business hours for the purpose of verifying the correctness of all calculations in such records.

2.                                      PERMITS; DMF(S) AND cGMP

2.1.                            Noramco will be responsible for obtaining [***] any licenses or permits, and any regulatory and government approvals necessary for the manufacture of API, provided that Manufacturing Quota is addressed in Article 8 below.

implemented only if and after the other Party consents to them, which consent shall not be unreasonably withheld.  The Party requesting a change in filed Specifications shall bear the financial costs of implementing such change.

3.                                      FORECASTS AND PURCHASE ORDERS FOR API

3.1.                            On [***] throughout the Term, Purchaser shall provide to Noramco a [***] rolling ([***]), binding (except as set forth below) forecast (each a “Forecast”) of the anticipated monthly purchases of API under this Agreement, provided that the initial Forecast shall be provided to Noramco no later than [***] after the Effective Date.  The Forecast will include quantities for planned regulatory filings.  The [***] Forecast shall be binding on Purchaser and shall constitute a firm commitment by Purchaser to issue a purchase order for the API indicated for such months, subject to availability of Manufacturing Quota and Procurement Quota, provided, however, that if necessary in light of significant changes in the market for the Products due to availability of a generic equivalent of the Products, regulatory actions or other developments materially and adversely affecting the market for the Products, the Parties will discuss in good faith and mutually agree upon a commercially reasonable reduction to such forecasts.  With respect to any Forecast submitted by Purchaser hereunder, Purchaser may request an increase of no greater than [***] in the quantity of API forecast [***] and Noramco shall take [***] efforts to accommodate such request.

3.2.                            With respect to each Forecast (and any increase to such Forecast), [***].

3.3.                            Purchaser shall place monthly purchase orders for API with Noramco, each of which shall specify quantities in kilograms and a delivery date that is not less than [***], nor more than [***], from the date of Noramco’s receipt of such purchase order (each, a “Purchase Order”).  Subject to this Section 3.3 and Article 8, Noramco shall supply and deliver such quantities of API to Purchaser as set forth in each Purchase Order, provided that, unless Noramco otherwise agrees in its sole discretion, each Purchase Order shall be consistent with the quantities set forth in the applicable Forecast provided in accordance with Section 3.1 and the delivery date restrictions set forth in this Section 3.3.  Each Purchase Order must be submitted with a certificate of available Procurement Quota or a completed DEA Form 222 which evidences that Purchaser shall be able to take delivery of the API subject to the Purchase Order; provided, however, that Noramco, in its sole discretion, may agree to accept a Purchase Order which specifies the amounts of API that are contingent upon future receipt of Procurement Quota.  In the event that Noramco accepts any Purchase Order which specifies that all or a portion of API is contingent upon receipt of Procurement Quota, the supply and purchase thereof shall be subject to Article 8.

4.                                      CONSIDERATION FOR SUPPLY OF API

4.1.                            The price of API to be sold to Purchaser during the Initial Price Term shall be based on the annual volume of API ordered by Purchaser as set forth on Appendix C (the “Supply Price”).  For the avoidance of doubt [***].

Confidential Information indicated by [***] has been omitted from this filing and filed separately with the Securities Exchange Commission.

6

4.2.                            After the Initial Price Term, a reasonable increase in the Supply Price shall be mutually agreed upon by the Parties [***].  In the event a mutual agreement is not reached on the price increase, the Supply Price shall be [***].

4.3.                            In addition to the foregoing, at any time during the Term, Noramco shall be entitled to adjust the Supply Price in the event of increases to the cost of raw materials or fees of third party contractors incurred by Noramco as compared with such costs on the Effective Date; provided, however, that such adjustments to the Supply Price shall not take effect until Noramco and Purchaser discuss such adjustments in good faith.  Such Supply Price increases shall be applicable to any and all orders placed more than [***] after Noramco has notified Purchaser of the increase in writing.  Purchaser shall be entitled to request that an independent certified accountant verifies the accuracy of any such Supply Price increases.

4.4.                            Purchaser shall pay Noramco for all supplied quantities of API within [***] from the date of invoice, provided that, pending resolution of any disagreement under Article 6, Purchaser is not obligated for any payment payable with respect to API for which Purchaser has delivered a written objection pursuant to Article 6.

4.5.                            All payments payable for the purchase of API will be made by electronic transfer of United States Dollars to an account designated in writing by Noramco.

4.6.                            Noramco will not be obligated to honor orders or shipments to Purchaser should Purchaser’s account with Noramco fall greater than [***] in arrears.

4.7.                            In addition to the Supply Price for quantities of API delivered hereunder, Purchaser shall pay Noramco any and all governmental taxes, charges or duties of every kind (excluding any tax based upon Noramco’s net income) that Noramco may be required to collect or pay upon sale, transfer or shipment of API to Purchaser.

5.                                      SHIPMENT OF API

5.1.                            Noramco shall make deliveries of API to Purchaser or its designate [***].  Each shipment of API delivered to Purchaser hereunder shall be accompanied by an invoice for the quantity of API included in such shipment.

5.2.                            In the event that a Purchase Order is delivered where delivery of any API thereunder is contingent upon Purchaser securing Procurement Quota, Noramco may require cash or satisfactory security prior to accepting such Purchase Order or shipments or deliveries of API hereunder.  The election by Noramco to require such cash or security shall not affect the obligation of Purchaser to take and pay for the ordered API.  Purchaser shall pay all costs and expenses, including reasonable attorneys’ fees, incurred by Noramco in the collection of any sum payable by Purchaser to Noramco under this Agreement.  Noramco shall be entitled to interest on any overdue sum at the maximum rate allowed by applicable law.

Confidential Information indicated by [***] has been omitted from this filing and filed separately with the Securities Exchange Commission.

6.                                      INSPECTION AND REJECTION

6.1.                            All API delivered to Purchaser hereunder may be inspected by Purchaser and rejected if the API does not meet the Specifications or has not been manufactured in accordance with cGMP(s) (any such API, “Nonconforming API”).  API will be deemed accepted if Noramco does not receive a written notice from Purchaser setting forth in reasonable detail the claimed visible nonconformity within [***] after delivery to Purchaser of such API or the claimed non-visible nonconformity within [***] after Purchaser’s discovery of such non-visible nonconformity, provided, however, in no event shall any API be rejected based on nonconformity less than [***] prior to its expiration date.

6.2.                            Upon receipt of a written notice that any API delivered hereunder is Nonconforming API within the time period specified in Section 6.1, Noramco will have [***] to inspect the allegedly Nonconforming API and make a reasonable assessment of the alleged nonconformance.  At Noramco’s request, Purchaser must promptly supply samples of the allegedly Nonconforming API or some other evidence of nonconformity that Noramco may reasonably specify.

6.3.                            If Noramco disagrees with Purchaser’s determination that API delivered hereunder is Nonconforming API, Noramco shall promptly notify Purchaser and, if the Parties are unable to resolve such disagreement within a [***] period, such disagreement will be investigated in accordance with the Quality Agreement.  If the Parties cannot agree after such investigation whether such API is in fact Nonconforming API, (a) if Purchaser alleges that such API does not meet the Specifications, then samples of such API will be submitted to a qualified independent laboratory mutually agreed to by Noramco and Purchaser for testing and such laboratory will use the test methods contained in the applicable Specifications or (b) if Purchaser alleges that such API has not been manufactured in accordance with cGMP(s), then such disagreement shall be referred to a mutually agreed upon third party expert for resolution which shall include root cause investigation, independent expert assessment, independent third party testing and replacement of API.  The determination of such laboratory or third party expert with respect to all or part of such API will be final and binding on the Parties, absent manifest error.  The fees and expenses of the laboratory or third party expert incurred in making such determination will be paid by Noramco, if the determination is made against Noramco or by Purchaser, if the determination is made against Purchaser.

6.4.                            If the Parties agree or there is a determination under Section 6.3 that any API delivered hereunder is Nonconforming API, Noramco, at its sole cost and expense and as Purchaser’s sole remedy shall, subject to Sections 10.4 and 10.5, promptly replace such Nonconforming API and reimburse Purchaser [***].  Nonconforming API will be returned to Noramco at its expense.

6.5                               During the Term and for [***] thereafter, Purchaser shall have the right, upon at least [***] notice, to inspect, during normal business hours, those areas of Noramco’s production facilities where API is manufactured, handled, packaged and stored, any facility or location where API is tensed, and to audit the records described in this Agreement.

Confidential Information indicated by [***] has been omitted from this filing and filed separately with the Securities Exchange Commission.

7.                                      PRODUCT COMPLAINTS, ADVERSE EXPERIENCES AND RECALLS

7.1.                            During the Term, Noramco shall assist Purchaser with any necessary investigation arising from customer complaints relating to Product in accordance with the Quality Agreement.  Without in any manner limiting the foregoing, each of Purchaser and Noramco shall comply with FDA requirements for complaint handling. Purchaser shall maintain a system for monitoring, investigating, and following up on adverse event reports received by it involving Product(s), and shall provide prompt notice to Noramco of any Product complaints, including, but not limited to, information concerning adverse drug events that are required to be reported to FDA, side effects, injury, toxicity, or sensitivity reaction in those instances where the adverse drug event can be attributed specifically to the API.

7.2.                            Each Party shall notify the other Party of any regulatory action or other action concerning the safety of the API in accordance with the Quality Agreement, including but not limited to FDA inspection reports, warning letters or import alerts.

7.3.                            In the event of a recall of Product that does not result from the breach of Noramco’s obligations under Section 2.4 to manufacture API in accordance with cGMP and the Specifications, as between Noramco and Purchaser, [***]  For the purposes of this Section 7.3, [***].

8.                                      MANUFACTURING INTERRUPTIONS, QUOTA RESTRICTIONS AND SHORTAGES

8.1.                            Manufacturing Interruptions.  Purchaser acknowledges that the day-to-day manufacturing operation of the facilities used by Noramco to produce API may be subject to interruptions, fluctuations, slow-downs, suspensions and reductions, due to a variety of reasons in the ordinary course of business (“Manufacturing Interruptions”).  If Noramco believes that a Manufacturing Interruption is reasonably likely to result in a material reduction of API available to be delivered to Purchaser, Noramco shall provide notice to Purchaser of, and consult with Purchaser about, such Manufacturing Interruption prior to or as soon as reasonably possible after the commencement of such Manufacturing Interruption.  After the termination of any Manufacturing Interruption that results in a material reduction of API, Noramco shall promptly communicate to Purchaser regarding the termination of such Manufacturing Interruption and the reason therefor, as well as any actions taken or planned to be taken to prevent a repeat event.

8.2.                            Manufacturing Quota Restrictions.  Purchaser further acknowledges that the production and supply of API is contingent upon DEA rules, orders or directives related to the Manufacturing Quota that may limit or restrict the manufacture or supply of API by Noramco to Noramco’s customers (“Manufacturing Quota Restrictions”).  If Noramco believes that a Manufacturing Quota Restriction is reasonably likely to result in a material reduction or suspension of the delivery of API to Purchaser, Noramco shall promptly consult with Purchaser to coordinate with respect to their respective obligations in accordance with Sections 8.4 and 8.5.

8.3.                            Procurement Quota Restrictions.  It is the sole responsibility of Purchaser, and Purchaser shall use [***] efforts, to obtain Procurement Quota for API, provided that Noramco shall reasonably cooperate with Purchaser to assist Purchaser in obtaining Procurement Quota.  Noramco acknowledges that Purchaser’s receipt of API manufactured by Noramco is contingent

Confidential Information indicated by [***] has been omitted from this filing and filed separately with the Securities Exchange Commission.

upon DEA rules, orders or directives related to the Procurement Quota that may limit or restrict Noramco’s customers from receiving API manufactured by Noramco (“Procurement Quota Restrictions”).  If Purchaser believes that a Procurement Quota Restriction is reasonably likely to result in Purchaser’s inability to take delivery of an API from Noramco in accordance with the delivery date set forth in a Purchase Order, Purchaser shall promptly consult with Noramco to coordinate with respect to their respective obligations in accordance with Section 8.4.

8.4.                            Failure to Obtain Quota.  Each Party shall use [***] efforts to prepare and plan for the supply and purchase of API(s) against Purchase Orders to be given in accordance with the Forecasts in anticipation of each Party receiving applicable quota from the DEA.  In the event that a Party does not obtain the necessary Manufacturing Quota or Procurement Quota, as the case may be, to allow it to perform its obligations under this Agreement, such Party shall promptly inform the other Party in writing.  In the event that there is not sufficient Manufacturing Quota or Procurement Quota with respect to an outstanding Purchase Order, such Purchase Order shall nonetheless remain valid and binding upon the Parties, provided that the Purchase Order delivery date will be adjusted by the Parties for a period not to exceed [***] so as to permit receipt of the necessary Manufacturing Quota or Procurement Quota, as the case may be.  In the event that Manufacturing Quota is not received by Noramco within [***] of the original delivery date set forth in a Purchase Order, then such Purchase Order may be, but is not required to be, cancelled by Purchaser by written notice to Noramco, which cancellation shall be Purchaser’s sole and exclusive remedy for the applicable Manufacturing Quota Restriction.  In the event that Purchaser does not obtain Procurement Quota within [***] of the original delivery date set forth in a Purchase Order, [***].

8.5.                            Allocation Among Customers and Cooperation.  Purchaser recognizes that, due to Manufacturing Interruptions or Manufacturing Quota Restrictions, Noramco may produce less API in any given time period than anticipated, and that Noramco may, at its discretion, allocate its available supply of API among its customers, itself, and its Affiliates [***].  Notwithstanding the above, Noramco shall (a) use [***] efforts to minimize interruptions in the supply of API and (b) use [***] efforts to coordinate with Purchaser to mitigate against the consequences of any shortages related to Manufacturing Interruptions or Manufacturing Quota Restrictions.

8.6.                            No Liability for Manufacturing Quota Restrictions.  Subject to Noramco’s compliance with its obligations set forth in this Article 8, Noramco shall not be liable to Purchaser for any damage, inconvenience, or any other consequences that may arise from Manufacturing Quota Restrictions.

9.                                      WARRANTIES; DISCLAIMER

9.1.                            Noramco hereby represents, warrants and covenants to Purchaser that:

9.1.1.                  it has the corporate authority to enter into this Agreement and to perform its obligations hereunder;
