not attributable to Core or its Affiliates’ practice of King’s Manufacturing Process in compliance with the terms and conditions of this Agreement.

     8.3 Indemnification Procedure.

          (a) Notice of Claim. The indemnified party (the “Indemnified Party”) shall give the indemnifying Party (the “Indemnifying Party”) prompt written notice (an “Indemnification Claim Notice”) of any Loss, action, or discovery of facts upon which such Indemnified Party intends to base a request for indemnification under Sections 8.1 or 8.2 (a “Claim”), but in no event shall the Indemnifying Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and amount of such Loss (to the extent that the nature and amount of such Loss are known at such time). The Indemnified Party shall furnish promptly to the Indemnifying Party copies of all papers and official documents received in respect of any Losses.

          (b) Control of Defense. At its option, the Indemnifying Party may assume the defense of any Claims by giving written notice to the Indemnified Party within 30 days after the Indemnifying Party’s receipt of an Indemnification Claim Notice; provided that the assumption of the defense of a Claim by the Indemnifying Party shall not be construed as an acknowledgment that the Indemnifying Party is liable to indemnify any Indemnified Party in respect of the Claim, nor shall it constitute a waiver by the Indemnifying Party of any defenses it may assert against any Indemnified Party’s Claim. Upon assuming the defense of a Claim, the Indemnifying Party may appoint as lead counsel in the defense of such Claim any legal counsel selected by the Indemnifying Party, which shall be reasonably acceptable to the Indemnified Party. In the event the Indemnifying Party assumes the defense of a Claim, the Indemnified Party shall immediately deliver to the Indemnifying Party all original notices and documents (including court papers) received by any Indemnified Party in connection with the Claim. Subject to clause (c) below, if the Indemnifying Party assumes the defense of a Claim, the Indemnifying Party shall not be liable to the Indemnified Party for any legal expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense, or settlement of such Claim. In the event that it is ultimately determined that the Indemnifying Party is not obligated to indemnify, defend, or hold harmless an Indemnified Party from and against any Claim, the Indemnified Party shall reimburse the Indemnifying Party for any and all costs and expenses (including attorneys’ fees and costs of suit) and any Losses incurred by the Indemnifying Party in its defense of such Claim with respect to such Indemnified Party.

          (c) Right to Participate in Defense. Without limiting Section 8.3(b), any Indemnified Party shall be entitled to participate in, but not control, the defense of a Claim and to employ counsel of its choice for such purpose; provided, however, that such employment shall be at the Indemnified Party’s own expense unless (i) the employment thereof has been specifically authorized by the Indemnifying Party in writing, (ii) the Indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 8.3(b) (in which case the Indemnified Party shall control the defense), or (iii) the interests of the Indemnified Party and the Indemnifying Party with respect to

such Claim are sufficiently adverse to prohibit the representation by the same counsel of both parties under Applicable Law, ethical rules, or equitable principles.

          (d) Settlement. With respect to any Losses relating solely to the payment of money damages in connection with a Claim and that will not result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affect the business of the Indemnified Party in any manner, and as to which the Indemnifying Party shall have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, the Indemnifying Party shall have the sole right to consent to the entry of any judgment, enter into any settlement, or otherwise dispose of such Loss, on such terms as the Indemnifying Party, in its sole discretion, shall deem appropriate. With respect to all other Losses in connection with Claims, where the Indemnifying Party has assumed the defense of the Claim in accordance with Section 8.3(b), the Indemnifying Party shall have authority to consent to the entry of any judgment, enter into any settlement, or otherwise dispose of such Loss; provided that it obtains the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld or delayed. The Indemnifying Party shall not be liable for any settlement or other disposition of a Loss by an Indemnified Party that is reached without the written consent of the Indemnifying Party. Regardless of whether the Indemnifying Party chooses to defend or prosecute any Claim, no Indemnified Party shall admit any liability with respect to, or settle, compromise, or dispose of, any Claim without the prior written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed).

          (e) Cooperation. If the Indemnifying Party chooses to defend or prosecute any Claim, the Indemnified Party shall cooperate in the defense or prosecution thereof and shall furnish such records, information, and testimony, provide such witnesses, and attend such conferences, discovery proceedings, hearings, trials, and appeals as may be reasonably requested in connection therewith. Such cooperation shall include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Claim, and making employees and agents available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder, and the Indemnifying Party shall reimburse the Indemnified Party for all its reasonable out-of-pocket expenses in connection therewith.

          (f) Expenses. Except as provided above, the reasonable and verifiable costs and expenses, including fees and disbursements of counsel, incurred by the Indemnified Party in connection with any Claim shall be reimbursed on a monthly basis in arrears by the Indemnifying Party, without prejudice to the Indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the Indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

     8.4 Insurance. During the Term and for 5 years thereafter, each Party shall procure and maintain at its own expense from a qualified and licensed insurer liability insurance or indemnity policies, in an amount not less than $[***] in the aggregate with

an indemnity to principals clause with respect to products liability and distribution, subject to such deductible or self-retention limits as either Party in its business discretion may elect. Such policies shall be blanket policies and shall insure against liability on the part of each Party and any of its Affiliates, as their interests may appear, due to injury, disability, or death of any person or persons, or injury to property, arising from the distribution of Products. Upon the execution of this Agreement and thereafter on January 1 of each year during the Term, each Party shall provide to the other a certificate of insurance (i) summarizing the insurance coverage and (ii) identifying any exclusions. Each Party shall promptly notify the other of any material adverse alterations to the terms of this policy or decreases in the amounts for which insurance is provided. Either Party may satisfy its obligations hereunder through self-insurance to the same extent.

     8.5 Limitation on Damages. EXCEPT WITH RESPECT TO THE GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT OF A PARTY, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR SPECIAL, EXEMPLARY, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, INCLUDING BUSINESS INTERRUPTION OR LOST PROFITS; PROVIDED, HOWEVER, THIS EXCLUSION IS NOT INTENDED TO, NOR SHALL, EXCLUDE ACTUAL OR COMPENSATORY DAMAGES OF THE AFFECTED PARTY, INCLUDING SPECIAL, EXEMPLARY, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, OWED TO THIRD PARTIES AS A RESULT OF A CLAIM PURSUANT TO THE INDEMNIFICATION OBLIGATIONS HEREOF.

     8.6 Product Liability Claims. As soon as it becomes aware, each Party will give the other prompt written notice of any defect or alleged defect in a Product, any injury alleged to have occurred as a result of the use or application of the Product, and any circumstances that may give rise to litigation or recall of a Product or regulatory action that may affect the sale or Manufacture of a Product, specifying, to the extent the party has such information, the time, place, and circumstances thereof and the names and addresses of the persons involved. Each Party will also furnish promptly to the other copies of all papers received in respect of any claim, action, or suit arising out of such alleged defect, injury, or regulatory action.

CONFIDENTIALITY

     9.1 Confidentiality Requirement. The Parties agree that the terms of the Confidentiality Agreement are incorporated herein by reference and shall govern the confidentiality obligations of the Parties. The Confidentiality Agreement shall continue in full force and effect for the term of this Agreement and survive any expiration or termination of this Agreement for the period set forth in Section 9 of the Confidentiality Agreement.

ARTICLE 10

TERM AND TERMINATION

     10.1 Term. This Agreement shall begin on the Effective Date and, unless this Agreement is terminated earlier in accordance with its terms, shall continue in effect until the expiration of the King Patent Rights (the “Term”).

     10.2 Termination. In addition to any other provision of this Agreement expressly providing for termination of this Agreement, this Agreement may be terminated as follows:

          (a) King may terminate this Agreement immediately:

               (i) upon notice to Core in the event that any Governmental Authority causes the withdrawal of the Branded Product or Authorized Generic Product from the market in any country in the Territory; or

               (ii) upon notice to Core in the event of a product recall (and if the recall is a voluntary recall, only if King also withdraws the Branded Product from the market); or

               (iii) if there is a change in Law that would prevent the sale of Authorized Generic Product;

          (b) This Agreement may be terminated at any time by either Party:

               (i) immediately upon written notice if the other Party shall file in any court or agency, pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for arrangement or for the appointment of a receiver or trustee of the other Party or of its assets, or if the other Party proposes a written agreement of composition or extension of its debts, or if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within 60 days after the filing thereof, or if the other Party shall propose or be a party to any dissolution or liquidation, or if the other Party shall make an assignment for the benefit of its creditors, or

               (ii) immediately upon written notice in the event of any material default by the other Party in the performance of any of its obligations herein contained, which default has not been cured by the defaulting Party within 60 days after receiving written notice thereof from the nondefaulting Party, or

               (iii) a decision that all claims of the Asserted Patents are invalid and/or unenforceable is entered by a court of competent jurisdiction from which decision no appeal (other than a petition for certiorari) has been or can be taken in an infringement case or declaratory judgment action.

          (c) King may terminate this Agreement with respect to all rights and obligations pertaining to the Authorized Generic Product, including without limitation Articles 3, 5 and 6 hereof, upon 30 days written notice to Core in the event that King’s pricing to 340(b) entities has an adverse effect on King’s Branded Product business (determined in King’s sole discretion).

     10.3 Effect of Termination.

          (a) The expiration or termination of this Agreement shall be without prejudice to any rights or obligations of the Parties that may have accrued prior to such termination, and all of the Parties’ rights and obligations under Article 1, Sections 2.4 and 2.5, Sections 4.1 and 4.2 and Articles 7 through 11, inclusive, shall survive the expiration or termination of this Agreement, provided, however, that Sections 2.4 and 2.5 of this Agreement shall survive the termination of this Agreement only if terminated pursuant to Section 10.2(b)(i), if terminated pursuant to Section 10.2(b)(ii) by Core for King’s material breach, or if terminated pursuant to Section 10.2(b)(iii) , and such sections shall not survive any other termination of this Agreement. For the avoidance of doubt, the termination, pursuant to Section 10.2(c), of the rights and obligations hereunder pertaining to the Authorized Generic Product shall have no effect on the rights and obligations of the parties hereunder with respect to the Core 800 mg Product, including without limitation Sections 2.4 and 2.5 hereof. Except as otherwise expressly provided herein, termination of this Agreement in accordance with the provisions hereof shall not limit remedies that may otherwise be available in law or equity.

          (b) Upon expiration or termination of this Agreement, each Party, at the request of the other, shall return all data, files, records, and other materials in its possession or control containing or comprising the other Party’s Proprietary Information.

          (c) Upon termination of this Agreement for any reason other than a breach by King of its obligations hereunder, all submitted but unfilled purchase orders for API (in the case that King is supplying Core with API) shall be honored by Core, unless otherwise agreed.

          (d) At King’s election, upon termination or expiration of this Agreement, (i) King will have the right to remove any King Equipment, without payment to Core therefor, and in such event, Core will, [***] of such termination, discontinue the use of the King Equipment, or (ii) Core will purchase the King Equipment from King by paying King the fair market value of the King Equipment, or (iii) King will transfer title to the King Equipment to Core. In addition, King agrees to negotiate in good faith with Core for a period of [***] following termination under Section 10.2(c), a sale of King’s rights to the Skelaxin and Metaxalone products to Core, so long as Core notifies King in writing, no later than the day of termination of this Agreement pursuant to Section 10.2(c), of Core’s desire to enter into such a transaction.

     All notices shall be deemed given when received by the addressee. General communications relating to quality issues in relation to the Quality Agreement may be made to corresponding person identified therein.

     11.2 Force Majeure. Neither Party shall be liable for delay in delivery or nonperformance, in whole or in part, nor shall the other Party have the right to terminate this Agreement except as otherwise specifically provided in this Section 11.2, where delivery or performance has been affected by one of the following conditions (to the extent they result in a substantial or material adverse effect on the Manufacturing capacity for Authorized Generic Product): fires, floods, embargoes, shortages, epidemics, quarantines, war, acts of war (whether war be declared or not), terrorism, insurrections, riots, civil commotion, or acts, omissions, or delays in acting by any governmental authority; provided that the Party affected by such a condition shall, within 10 days of its occurrence, give notice to the other Party stating the nature of the condition, its anticipated duration, and any action being taken to avoid or minimize its effect. The suspension of performance shall be of no greater scope and no longer duration than is reasonably required, and the nonperforming Party shall use its reasonable best efforts to remedy its inability to perform; provided, however, that in the event the suspension of performance continues for 60 days after the date of the occurrence, and such failure to perform would constitute a material breach of this Agreement in the absence of such force majeure event, the non-affected Party may terminate this Agreement immediately by written notice to the affected Party.

     11.3 Independent Contractor. The Parties to this Agreement are independent contractors. Nothing contained in this Agreement shall be construed to place the Parties in the relationship of employer and employee, partners, principal, and agent or a joint venture. Neither Party shall have the power to bind or obligate the other Party nor shall either Party hold itself out as having such authority.

     11.4 Waiver. No waiver by either Party of any provision or breach of this Agreement shall constitute a waiver by such Party of any other provision or breach, and no such waiver shall be effective unless made in writing and signed by an authorized representative of the Party against whom waiver is sought. No course of conduct or

dealing between the Parties will act as a modification or waiver of any provision of this Agreement. Either Party’s consent to or approval of any act of the other Party shall not be deemed to render unnecessary the obtaining of that Party’s consent to or approval of any subsequent act by the other Party.

     11.5 Entire Agreement. This Agreement (together with all Exhibits and Schedules hereto, which are hereby incorporated by reference), the Quality Agreement, the Confidentiality Agreement, and the Master Tech Transfer Agreement constitute the final, complete, and exclusive agreement between the Parties relating to the subject matter hereof and supersede all prior conversations, understandings, promises, and agreements relating to the subject matter hereof. To the extent that any inconsistencies exist between this Agreement and the Quality Agreement, this Agreement shall control. Neither Party has relied upon any communications, representations, terms or promises, verbal or written, not set forth herein.

     11.6 Binding Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of King and Core and their respective successors, heirs, executors, administrators, and permitted assigns. This Agreement may not be assigned by either Party without the prior written consent of the other Party, not to be unreasonably withheld or delayed; except that either Party may assign this Agreement without the other Party’s consent to an Affiliate or to a person or entity who acquires all or substantially all of the business of the assigning Party to which this Agreement relates, by merger, sale of assets, or otherwise, or to one or more financial institutions providing financing to such Party, pursuant to the terms of the relevant security agreement; provided that such assignee or transferee shall also promptly agree in writing to be bound by the terms and conditions of this Agreement.

     11.7 Amendment; Modification. This Agreement may not be amended, modified, altered, or supplemented except by a writing signed by both Parties. No modification of any nature to this Agreement and no representation, agreement, arrangement, or other communication shall be binding on the Parties unless such is expressly contained in writing and executed by the Parties as an amendment to this Agreement. This Agreement may not be amended in any respect by any purchase order, invoice, acknowledgment, or other similar printed document issued by either Party.

     11.8 Governing Law. This Agreement will be construed in accordance with the laws of the State of New York, without regard to any choice of law provisions.

     11.9 Severability. If any provision of this Agreement is found by a proper authority to be unenforceable, that provision shall be severed and the remainder of this Agreement will continue in full force and effect.

     11.10 Construction. Unless the context of this Agreement otherwise requires: (a) words of any gender include each other gender; (b) words using the singular or plural number also include the plural or singular number, respectively; (c) the terms “hereof,” “herein,” “hereby,” and derivative or similar words refer to this entire Agreement; (d) the terms “Article,” “Section,” “Exhibit,” “Schedule,” or “clause” refer to the specified Article, Section, Exhibit, Schedule, or clause of this Agreement; (e) “or” is disjunctive but not necessarily exclusive; (f) the term “including” or “includes” means “including without limitation” or “includes without limitation”; and (g) references to any agreement shall mean such agreement, as such agreement may amended, modified or supplemented, from time to time in accordance with its terms. Whenever this Agreement refers to a number of days, such number shall refer to calendar days unless business days are specified. The captions and headings of this Agreement are for convenience of reference only and in no way define, describe, extend, or limit the scope or intent of this Agreement or the intent of any provision contained in this Agreement. The language of this Agreement shall be deemed to be the language mutually chosen by the Parties, and no rule of strict construction shall be applied against either Party hereto.

     11.11 Third Party Beneficiaries. This Agreement is not intended to confer upon any non-party rights or remedies hereunder, except as may be received or created as part of a valid assignment.

     11.12 Further Assurances. Each of the Parties agrees to duly execute and deliver, or cause to be duly executed and delivered, such further instruments and do and cause to be done such further acts and things, including the filing of such additional assignments, agreements, documents, and instruments, that may be necessary or as the other Party hereto may at any time and from time to time reasonably request in connection with this Agreement or to carry out more effectively the provisions and purposes of, or to better assure and confirm unto such other Party its rights and remedies under, this Agreement.

     11.13 Remedies. The remedies provided hereunder and under the governing law are cumulative and not exclusive.

     11.14 FTC Filings. Within ten (10) days of the execution hereof by all Parties hereto, this Agreement shall be filed by each Party with the FTC and with federal and state governmental or regulatory authorities to the extent required by Applicable Law.
