For clarity, each Order Forecast shall itemize the applicable quantity (i.e., the unit of Drum or naked bottle, but not limited to such unit) of the Product and its placebo (if applicable) for each of Development and Commercial use. Each Order Forecast shall be made in good faith for budget and capacity planning purposes only and shall be non-binding on Kissei and Rigel, except as provided in Section 2.2(b). The Parties shall discuss and review the Order Forecast at each regularly scheduled meeting of the JSC established by the Parties under the Collaboration and License Agreement (or by a subcommittee established by the JSC to oversee the manufacture and supply of the Product). The Order Forecast will be in substantially the form attached hereto as Exhibit B.

2.3 Purchase Orders; Delivery Terms.
(a)Purchase Orders. On or before the ** of each Calendar Quarter during the Term of this Supply Agreement, Kissei shall submit to Rigel a binding purchase order (a “Purchase Order”) for the Product and its placebo (if applicable) to be delivered during the next Calendar Quarter of the most recent Order Forecast for Commercial use and/or Development use in quantities ** those set forth for such Calendar Quarter in the most recent Order Forecast. The Purchase Order will be in substantially the form attached hereto as Exhibit C. Rigel shall accept or reject each Purchase Order in writing within ** after its receipt of such Purchase Order; provided, however, that Rigel shall accept such Purchase Order if the quantities of the Product and its placebo (if applicable) ordered for each of Development and Commercial use in such Purchase Order are ** the quantities for such use set forth in the most recent Order Forecast, as applicable.

Rigel hereby agrees to defend, indemnify, and hold harmless Kissei and its Affiliates and their respective directors, officers, employees, and agents (each, a “Kissei Indemnitee”) from and against any and all liabilities, expenses, and losses including any product liability, personal injury, property damage, including reasonable legal expenses and attorneys’ fees (collectively, “Losses”), to which any Kissei Indemnitee may become subject as a result of any claim, demand, action, or other proceeding by any Third Party to the extent such Losses arise out of or result from: (a) the negligence or willful misconduct of any Rigel Indemnitee, or (b) the breach by Rigel of any warranty, representation, covenant, or agreement made by Rigel in this Supply Agreement; except, in each case (a)-(b), to the extent such Losses arise out of any activities set forth in Section 9.2(a), (b), (c), or (d) for which Kissei is obligated to indemnify any Rigel Indemnitee(s) under Section 9.2.
9.2 Indemnification by Kissei. Kissei hereby agrees to defend, indemnify, and hold harmless Rigel, its Affiliates, and licensees and their respective directors, officers, employees, and agents (each, a “Rigel Indemnitee”) from and against any and all Losses to which any Rigel Indemnitee may become subject as a result of any claim, demand, action, or other proceeding by any Third Party to the extent such Losses arise out of: (a) the negligence or willful misconduct of any Kissei Indemnitee, (b) the breach by Kissei of any warranty, representation, covenant, or agreement made by Kissei in this Supply Agreement, (c) the Finish Manufacture, export, import, storage, packaging, or labeling, by or on behalf of Kissei or its Affiliates or sublicensees, of any Product supplied by Rigel hereunder, or (d) the commercialization of any Product supplied by Rigel hereunder; except, in each case (a)-(d), to the extent such Losses arise out of any activities set forth in Section 9.1(a) or (b) for which Rigel is obligated to indemnify any Kissei Indemnitee(s) under Section 9.1.
9.3 Indemnification Procedures. A party that intends to claim indemnification under this Article 9 (the “Indemnitee”) shall promptly notify the indemnifying Party (the “Indemnitor”) in writing of any Third Party claim, demand, action, or other proceeding (each, a “Claim”) in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor shall have sole control of the defense or settlement thereof. The Indemnitee may participate at its expense in the Indemnitor’s defense of and settlement negotiations for any Claim with counsel of the Indemnitee’s own choice. The indemnity arrangement in this Article 9 shall not apply to amounts paid in settlement of any action with respect to a Claim if such settlement is effected without the consent of the Indemnitor, which consent shall not be unreasonably withheld or delayed. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any action with respect to a Third Party Claim shall only relieve the Indemnitor of its indemnification obligations under this Article 9 if and to the extent the Indemnitor is actually prejudiced thereby. The Indemnitee shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action with respect to a Claim covered by this indemnification.
9.4 Insurance. Each Party, at its own expense, shall maintain insurance as set forth in Section 12.4 of

NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 9.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTIONS 9.1 OR 9.2, OR DAMAGES AVAILABLE FOR A PARTY’S BREACH OF CONFIDENTIALITY OBLIGATIONS IN Article 5. Without limiting the generality of the foregoing, Rigel’s obligationS and liability in connection with its supply obligations under this Supply Agreement (including in connection with any supply shortage, delays, and quality and other matters and Rigel’s indemnification obligations to Kissei under this Supply Agreement) shall be limited to the extent of the remedies actually obtained and recovered by Rigel from its contract manufacturers under the supply agreements between Rigel and the applicable contract manufacturer.

(a)in connection with the assignment of the Collaboration and License Agreement to a Third Party as set forth in Section 15.5 of the Collaboration and License Agreement; or
(b)to an Affiliate, provided that the assigning Party shall remain liable and responsible to the non-assigning Party hereto for the performance and observance of all such duties and obligations by such Affiliate.

The rights and obligations of the Parties under this Supply Agreement shall be binding upon and inure to the benefit of the successors and permitted assigns of the Parties specified above, and the name of a Party appearing herein will be deemed to include the name of such Party’s successors and permitted assigns to the extent necessary to carry out the intent of this Section 11.4.

11.10 No Waiver. The failure of a Party to insist upon strict performance of any provision of this Supply Agreement or to exercise any right arising out of this Supply Agreement shall neither impair that provision or right nor constitute a waiver of that provision or right, in whole or in part, in that instance or in any other instance.
