In May 2005, the Company entered into an agreement to grant certain exclusive marketing rights for its enoxaparin product to Andrx Pharmaceuticals, Inc., or Andrx, which generally extends to the U.S. retail pharmacy market. To obtain such rights, Andrx made a non-refundable, upfront payment of $4.5 million to the Company upon execution of the agreement, which was classified as deferred revenues. Under the agreement, the Company is paid a fixed cost per unit sold to Andrx and also shares in the gross profits (as defined) from Andrx’s sales of the product in the U.S. retail pharmacy market. In November 2006, Watson Pharmaceuticals, Inc., or Watson, acquired Andrx and all of the rights and obligations associated with the agreement. In January 2013, Watson adopted Actavis, Inc. as its new global name. In March 2015, Actavis acquired Allergan plc and adopted Allergan plc as its new global name in June 2015. In January 2012, the Company launched enoxaparin, beginning the seven-year period in which Actavis has the exclusive marketing rights for the Company’s enoxaparin product in the U.S. retail pharmacy market and the start of the Company’s recognition of the $4.5 million deferred revenue over this period on a straight-line basis. Actavis has an option to renew the agreement for an additional three years. As of June 30, 2016 and December 31, 2015, the balance of the deferred revenue was $1.7 million and $2.0 million, respectively. On June 30, 2016, the Company and Actavis agreed to terminate the agreement upon the earlier of (i) January 1, 2017, and (ii) such earlier date that is 30 days after Actavis notifies the Company in writing that Actavis has less than 30 days inventory of the enoxaparin product remaining in Actavis’s possession or scheduled to be delivered pursuant to the pending purchase orders. The Company will recognize the remaining balance of the deferred revenue of $1.7 million as of June 30, 2016 over the period from July 1, 2016 through December 31, 2016, on a straight-line basis as a result of the revised estimate of the contractual period. The Company manufactures its enoxaparin product for the retail market according to demand specifications of Actavis. Upon shipment of enoxaparin to Actavis, the Company recognizes product sales at an agreed transfer price and records the related cost of products sold. Based on the terms of the Company’s distribution agreement with Actavis, the Company is entitled to a share of the ultimate profits based on the eventual net revenue from enoxaparin sales by Actavis to the end user less the agreed transfer price originally paid by Actavis to the Company. Actavis provides the Company with a quarterly sales report that calculates the Company’s share of Actavis enoxaparin gross profit. The Company records its share of Actavis gross profit as a component of net revenue. Supply Agreement with MannKind Corporation On July 31, 2014, the Company entered in a supply agreement with MannKind Corporation, or MannKind, pursuant to which the Company will manufacture for and supply to MannKind certain quantities of RHI for use in MannKind’s product Afrezza®. Under the terms of the supply agreement, the Company will be responsible for manufacturing the RHI in accordance with MannKind’s specifications and agreed-upon quality standards. MannKind has agreed to purchase annual minimum quantities of RHI under the supply agreement of an aggregate amount of approximately €120.1 million, or approximately $146.0 million, in calendar years 2015 through 2019. MannKind paid a non-refundable reservation fee to the Company in the amount of €11.0 million, or approximately $14.0 million upon entry into the agreement. Under the agreement, the non-refundable reservation fee was considered as partial payment for the purchase commitment quantity for 2015. The Company classified the amount as deferred revenue. As of December 31, 2015, the full amount of the deferred revenue has been recognized. Unless earlier terminated, the term of the supply agreement expires on December 31, 2019, and can be renewed for additional, successive two-year terms upon 12 month’s written notice given prior to the end of the initial term or any additional two-year term. MannKind and the Company each have customary termination rights, including termination for material breach that is not cured within a specific time frame or in the event of liquidation, bankruptcy, or insolvency of the other party. In addition, MannKind may terminate the supply agreement upon two years’ prior written notice to the Company without cause or upon 30 days prior written notice to the Company if a controlling regulatory authority withdraws approval for Afrezza®; provided, however, in the event of a termination pursuant to either of these scenarios, the provisions of the supply agreement require MannKind to pay the full amount of all unpaid purchase commitments due over the initial term within 60 calendar days of the effective date of such termination. In January 2015, the Company entered into a supply option agreement with MannKind, pursuant to which MannKind will have the option to purchase RHI, for use in MannKind’s product Afrezza®, in addition to the amounts specified in the July 2014 supply agreement. Under the agreement, MannKind has the option to purchase additional RHI in calendar years 2016 through 2019.

By mutual agreement, MannKind did not purchase the full contractually obligated quantities of RHI in 2015. The 2015 sales of RHI to MannKind were $20.8 million. In October 2015, MannKind informed the Company they were not going to exercise the option to purchase additional quantities of RHI for 2016 under the supply option agreement. Accordingly, MannKind paid the Company a capacity cancellation fee in October 2015 for not exercising its minimum annual purchase option for 2016. The Company recognized this payment as revenue in fiscal 2015. In the six months ended June 30, 2016, sales of RHI to MannKind totaled $3.8 million. The Company is currently in discussions with MannKind regarding the timing of future purchases. Collaboration Agreement with a Medical Device Manufacturer The Company has entered into a collaboration agreement with a medical device manufacturer to develop a drug delivery system to be used by the Company for one of its pipeline products. As of June 30, 2016 the Company has paid an upfront payment of $0.5 million and $0.7 million in milestone payments under this agreement, which were classified as research and development expense. The Company is obligated to pay up to an additional $1.3 million if certain milestones are met. As of June 30, 2016, no such obligation existed. If the medical device manufacturer is successful in the development of this drug delivery system and the Company’s pipeline products receive appropriate regulatory approval, the Company intends to enter into a commercial supply agreement with such medical device manufacturer for a minimum purchase of 1.0 million units during the first 12 months. Operating Lease Agreements The Company leases real and personal property, in the normal course of business, under various non-cancelable operating leases. The Company, at its option, can renew a substantial portion of its leases, at the market rate, for various renewal periods ranging from one to six years. Rental expense under these leases for the three and six months ended June 30, 2016, was approximately $0.9 million and $1.7 million, respectively, compared to $0.9 million and $1.7 million for the three and six months ended June 30, 2015, respectively. Purchase Commitments As of June 30, 2016, the Company has entered into commitments to purchase equipment and raw materials for an aggregate of $16.9 million. The Company anticipates that most of these commitments will be fulfilled by 2017. The Company entered into agreements with a Chinese governmental entity to acquire land-use rights to real property in Nanjing, China. Under the terms of these agreements, the Company committed to invest capital in its wholly-owned subsidiary, ANP, and to develop these properties as an API manufacturing facility for the Company’s pipeline products. In conjunction with these agreements, ANP modified its business license on July 3, 2012, to increase its authorized capital. As of June 30, 2016, the Company had invested approximately $49.0 million in ANP of its registered capital commitment of $61.0 million. The Company has committed to invest an additional $12.0 million in ANP by December 2017. This investment in ANP will result in cash being transferred from the U.S. parent company to ANP. Per these agreements, in January 2010, the Company acquired certain land-use rights with a carrying value of $1.2 million. In addition, the Company purchased additional land-use rights in November 2012 for $1.3 million. The Company committed to spend approximately $15.0 million in land development. The agreements require the construction of fixed assets on the property and specified a timetable for the construction of these fixed assets. The current pace of development of the property is behind the schedules described in the purchase agreements and, per the purchase agreement, potential monetary penalties could result if the development is delayed or not completed in accordance with the guidelines stated in the purchase agreements. The Company is in discussions with the Chinese government regarding the development and believes that the likelihood of incurring any penalty is remote.
