     8.4 Requirements for King Reimbursement of Acura Development Expenses. King shall pay Acura only for Acura Development Expenses incurred in direct connection with this Agreement pursuant to a Development Plan, as it may be amended from time to time, up to a cap of the total budget set forth in such Development Plan; it being understood that in the event that the Parties agree that Acura shall conduct any Development activities for Products other than Product A, the applicable Development Plan shall include a mutually agreeable budget for such activities. The Parties intend that each such budget shall constitute the Parties’ then best estimate of the funds required to timely complete such Development. In no event shall Acura charge King any amounts in excess of the cap on the total budget as set forth in a budget in the applicable Development Plan (“Total Cap”), nor shall King be liable to pay such amounts; provided further that in no event shall Acura be required to perform Development activities which would not be eligible for reimbursement.

     8.5 Invoices. Within five (5) business days after the end of each month, Acura shall provide King with a good faith estimate for all Acura Development Expenses incurred by Acura for such month. In addition, within thirty (30) days after the end of each Calendar Quarter, Acura shall provide King with an invoice for all Acura Development Expenses incurred by Acura for such Calendar Quarter which invoice shall set forth the details of the charges for each activity together with appropriate documentation and a detailed comparison of such charges for such Calendar Quarter as well as year to date for such Calendar Year against the applicable Development Plan(s) and budget(s). Costs and expenses of Third Parties invoiced to King shall be fully detailed. Within thirty (30) days after the date of each such invoice, King shall pay in full such invoice. If any portion of an invoice is disputed, then King shall pay the undisputed amounts as set forth in the preceding sentence and the Parties shall use good faith efforts to reconcile the disputed amount as soon as practicable. Notwithstanding the previous sentence, if King disputes a charge or charges on an invoice, King will pay the amount ultimately determined to be due, if any, within thirty (30) days after King and Acura, acting in good faith, resolve the dispute. Where Acura does not receive payment due to it pursuant to this Section 8.5 within the time specified, interest shall accrue on the sum due and owing to Acura at the rate set forth in Section 10.2(b).

     8.6 Future Product Option Exercise.

          (a) For [***] after the receipt by King of a reasonably sufficient amount of data to demonstrate that a potential Future Product has achieved a successful Proof of Concept (“Future Product Option Term”), King shall have the option of any or all of the following:

               (i) paying a [***] fee (such fee to be non-refundable and non-creditable) to Acura, for up to [***] of an [***] product; provided that in the event that pursuant to and as permitted by Section 2.1(f) King has undertaken the Proof of Concept Development with respect to such potential Future Product, then the foregoing payment to Acura under this Section 8.6(a)(i) for [***] Products shall be reduced by the total amount of Development costs and expenses incurred by King in conducting such Proof of Concept Development, which costs and expenses for such [***] Products shall be (A) substantially similar to the Acura Development Expenses that Acura is permitted to incur under Section 8.3, (B) provided to Acura in form and detail substantially similar to what is required of Acura under Section 8.5, and (C) for an [***] Product capped at an amount such that in no event shall the payment to Acura pursuant to this Section 8.6(a)(i) be reduced by more than [***].

               (ii) paying a [***] fee (such fee to be non-refundable and non-creditable) to Acura, for up to [***] or

               (iii) relinquishing its Future Product Option to such potential Future Product, whereupon Acura shall retain all rights to such potential Future Product.

          (b) From and after the exercise of its Future Product Option with respect to a potential Future Product, King shall assume responsibility for all of the activities, costs and expenses related to the further Development and Commercialization of the applicable Future Product.

ARTICLE 9
ROYALTIES

     9.1 Royalty Payments. King shall pay to Acura royalty payments based on the Calendar Year Net Sales of all Products Commercialized by King (or its Affiliates or sublicensees) in the Territory based on the Net Sales ranges and corresponding applicable royalty rates (the “Applicable Royalty Rate”) set forth in Table 9.1. The royalty payments for Net Sales of Products for each of the first three Calendar Quarters of a Calendar Year shall be calculated by first multiplying the actual Net Sales for such Calendar Quarter by four (4) (the “Projected Annual Net Sales”) to determine, based on Table 9.1, the Applicable Royalty Rate for such Calendar Quarter. The actual Net Sales for such Calendar Quarter shall then be multiplied by the Applicable Royalty Rate for such Calendar Quarter to determine the royalty payment to Acura for such Calendar Quarter. The royalty payment for Net Sales of Products for the fourth Calendar Quarter of each Calendar Year shall be calculated by multiplying the actual Net Sales for such entire Calendar Year times the Applicable Royalty Rate from Table 9.1 applicable to such entire Calendar Year Net Sales less the sum of the royalty payments previously made for the first, second and third Calendar Quarters of such Calendar Year.

          (a) Term of Royalty Payments. King’s obligation to make royalty payments to Acura under this Section 9.1 shall commence twelve (12) months after the First Commercial Sale of the first Product in any country in the Territory (the “Royalty Commencement Date”) and shall expire upon the later of (i) expiration of the last to expire Valid Claim Covering a Product in such country, or (ii) fifteen (15) years from the First Commercial Sale of such Product in such country.

          (b) Timing of Royalty Payments and Reports. King shall make such royalty payments to Acura within forty-five (45) days after the end of each Calendar Quarter beginning with the first Calendar Quarter after the Royalty Commencement Date. Beginning with the month of the First Commercial Sale, within five (5) business days after the end of each month, King shall provide to Acura a good faith estimate of Net Sales for such month.

          (c) Partial Calendar Year True-Up. In addition, in the event the first Calendar Year for which royalty payments are due is a partial Calendar Year, the Parties shall undertake a one-time true-up royalty recalculation following the twelve (12) month anniversary of the Royalty Commencement Date (when a full twelve (12) month period (365 days) of Net Sales data is available beginning with the first Net Sale on which royalties are due). Based on such full twelve (12) months of data, the Applicable Royalty Rate shall be selected from Table 9.1. If such royalty rate is the same as the royalty rate(s) that had been previously applied to some or all of such first partial Calendar Year with respect to which royalties were due, then there shall be no adjustment in such royalty payments. However, where such royalty rate is greater or less than the royalty rate(s) that had been previously applied to some or all of such first partial Calendar Year with respect to which royalties were due, the difference shall be applied to the applicable Net Sales and paid as additional royalties or deducted from royalties due to Acura hereunder within forty-five (45) days after such twelve (12) month anniversary of the Royalty Commencement Date.

ARTICLE 10
ACCOUNTING AND AUDITING

               (ii) Details relating to any milestone payments to Acura.

          (b) Subject to Sections 8.5 and 10.4, in case of any delay in payment by a Party to the other Party, interest on the overdue payment shall accrue at an annual interest rate, compounded monthly, equal to the U.S. Prime Rate as reported in The Wall Street Journal, plus one and a half percentage points (1.5%), as determined for each month on the last business day of that month, assessed from the day payment was initially due. The foregoing interest shall be due from such delinquent Party without any special notice.

          (c) Currency Conversion. Whenever, for the purpose of calculating any sums due under this Agreement, conversion from any foreign currency shall be required, such conversion shall be made as follows: (i) when calculating the Net Sales, the amount of such sales in foreign currencies shall be converted into United States dollars using the average rate of exchange for such currencies for the relevant period, and (ii) when calculating Development expenses that are incurred in a currency other than in United States dollars, the amount in foreign

currencies shall be converted into United States dollars using the exchange rates for such currencies for the average monthly rate of the respective invoice. In respect of (i) and (ii) above, such exchange rate shall be the mid-price exchange rate taken from The Wall Street Journal as published on the date of the relevant invoice or such other publication as may be agreed between the Parties from time to time.

     10.3 Taxes. If the laws or regulations of any country in the Territory require withholding of taxes of any type, levies on Acura or its Affiliates, or other charges against Acura or its Affiliates with respect to any amounts payable under this Agreement to Acura, King shall make such withholding payments as may be required for and on behalf of Acura or its Affiliates to the proper governmental authority and shall subtract such withholding payments from the royalties due hereunder.

          (b) Such audits shall be conducted during normal business hours upon reasonable prior written notice from the auditing Party in such a manner as to not unnecessarily interfere with the audited Party’s or its Affiliate’s or sublicensee’s normal business activities, and shall be permitted with respect to records and books covering and including the three (3) years immediately preceding the date of notification of the audit. The accountants shall report its conclusions and calculation to both Parties; provided, however; that in no event shall the accountants disclose information of the audited party except to the extent necessary to verify the accuracy of the payments due under this Agreement, and at the request of the audited party such accountants shall execute appropriate non-disclosure agreements.

          (c) The auditing Party shall use all information, data, documents and abstracts obtained during an audit conducted pursuant to this Section 10.4 solely for the purposes described in Section 10.4(a). The auditing Party shall treat all such information, data, documents and abstracts as the audited Party’s Confidential Information subject to Article 12 of this Agreement and, except in the event of a dispute between the Parties regarding amounts payable hereunder or the results of any audit, the auditing Party shall not retain such information, data, documents and abstracts for more than three (3) years from the end of the Calendar Year to which each shall pertain.

          (d) If any audit hereunder reveals an underpayment, the Party responsible for the underpayment shall promptly make up such underpayment. If any audit hereunder reveals an overpayment, the Party holding the overpayment shall promptly reimburse such overpayment. The auditing Party shall bear the full cost of any audit under this Section 10.4, unless such audit discloses an underpayment by the audited Party of more than five percent (5%) of the amount owed hereunder in which case the audited Party shall bear the full cost of such audit.

          (e) The failure of an auditing Party to request verification of any payment calculation within the three (3) year period following receipt of such payment shall be considered acceptance of such calculation by the auditing Party.

Notwithstanding anything else to contrary under this Agreement, and without limiting any right or remedy King may otherwise have under this Agreement or at law or in equity: (a) King shall, after consulting with Acura, have the right (but not the obligation) to enter into intellectual property license agreements with such Third Parties as King reasonably believes to be necessary to avoid or settle allegations or claims regarding freedom to operate (other than for trademarks or copyrights) against a Product (other than the [***] formulation characteristics or technology of a Product) by such Third Party against either Party to this Agreement and (b) King may deduct from and set off against any royalties owed to Acura hereunder fifty percent (50%) of any royalties and other license payments paid under such license agreements to such Third Parties, up to a maximum amount such that the resulting royalties shall not be less than eighty percent (80%) of what would otherwise be payable to Acura hereunder at the Applicable Royalty Rate (for example, when the Applicable Royalty Rate is 5%, then deductions pursuant to this Section 11.5 shall not reduce the Applicable Royalty Rate payable to Acura below 4%, or for example if the Applicable Royalty Rate is 20%, then deductions pursuant to this Section 11.5 shall not reduce the Applicable Royalty Rate below 16%.

     11.6 Patent Term Extensions. The Parties shall cooperate, if necessary and appropriate, with each other in gaining patent term extension wherever applicable to Aversion Patent Rights in the Territory that Cover Products. The Parties shall, if necessary and appropriate, use reasonable efforts to agree upon a joint strategy relating to patent term extensions, but, in the absence of mutual agreement with respect to any extension issue in the Territory, if Acura does not wish to file for an extension of an Aversion Patent Right in the Territory that Covers a Product, then Acura shall timely let King know sufficiently in advance so as to permit King to request Acura to file for such extension, in which case, Acura shall file such extension at King’s expense.

     11.7 Patent Marking. King agrees to comply with the patent marking statutes in each country in the Territory in which Products are sold by King, its Affiliates and/or its sublicensees.

          (b) Non-Use of Similar Marks. Notwithstanding any other provision in this Agreement, during the Term, neither Party nor its Affiliates shall market, promote, sell and/or distribute any product (other than the Products) under the Trademarks or any substantially similar trade names or trademarks.

          (c) Trademark Filing and Expenses. Acura shall be solely responsible for the filing and maintenance of the Trademarks in the Territory and all costs and expenses related thereto.

          (d) Trademark Infringement.

               (i) With respect to any and all claims instituted by Third Parties against Acura or King or any of their respective Affiliates for trademark infringement involving the use, sale, license or marketing of the Products (each, a “Trademark Infringement Claim”), King shall be solely responsible for any and all losses arising out of or resulting from such Trademark Infringement Claims. Acura shall assist King and cooperate in the defense and settlement of such Trademark Infringement Claims at King’s request.

               (ii) In the event that a Party becomes aware of actual or threatened infringement of the Trademark, that Party shall promptly notify the other Party in writing (a “Trademark Infringement Notice”). Acura shall have the right, but not the obligation, to bring an action with respect to such infringement against any Third Party for infringement of the Trademark. In the event that Acura does not pursue an enforcement action within a period of sixty (60) days following the Trademark Infringement Notice, then King shall have the right to bring such action at its own cost. If King is not recognized by the applicable court or other relevant body as having the requisite standing to pursue such action, then King may join Acura as party-plaintiff. If Acura elects to pursue such infringement action, King may (i) elect to participate in such action, in which case King shall bear one-half of the out-of-pocket costs and expenses of the action (including court costs, reasonable fees of attorneys, accountants and other experts and other expenses of litigation or proceedings) and shall share any recovery in such amount as the greater of (a) their costs for such action and (b) in proportion to their actual damages, or (ii) elect not to participate in such action, in which case King shall have no obligation to pay for any of the costs or expenses of the action and shall not receive any portion of any recoveries and Acura shall bear all costs and expenses of the action and retain all recoveries.

Notwithstanding the foregoing, the Receiving Party may disclose Confidential Information of the Disclosing Party to the Receiving Party’s directors, officers, employees, Affiliates, consultants, subcontractors, sublicensees or agents to the extent reasonably necessary to carry out its obligations under this Agreement, provided that such directors, officers, employees, Affiliates, consultants, subcontractors, sublicensees or agents have been advised of the confidential nature of such information and have agreed to maintain such information as confidential to the same extent required by this Article 12.

     12.2 Exceptions to Definition of Confidential Information. Confidential Information shall not include information that the Receiving Party can demonstrate:

          (a) was known by the Receiving Party or its Affiliates prior to the date it was disclosed to the Receiving Party or its Affiliates by the Disclosing Party or its Affiliates, as evidenced by the prior written records of the Receiving Party or its Affiliates;

          (b) is lawfully disclosed to the Receiving Party or its Affiliates by a Third Party rightfully in possession of such information, either before or after the date of the disclosure to the Receiving Party or its Affiliates;

          (d) is independently developed by the Receiving Party or its Affiliates without reference to or reliance upon any Confidential Information of the Disclosing Party or its Affiliates; or

          (e) is required to be disclosed by the Receiving Party or its Affiliates pursuant to a judicial or governmental order, provided that the Receiving Party gives the Disclosing Party sufficient notice to permit Disclosing Party to seek a protective order or other similar order with respect to such Information.

     12.3 Exceptions. The restrictions set forth in this Article 12 shall not prevent either Party from (i) disclosing Confidential Information in connection with preparing, filing, prosecuting or maintaining the Aversion Patent Rights covering a Product in accordance with Article 11, (ii) disclosing Confidential Information to governmental agencies to the extent required or desirable to obtain a Regulatory Approval, (iii) disclosing Confidential Information to potential private investors (under a confidentiality agreement at least as restrictive as the provisions of this Article 12) in connection with fundraising activities, (iv) disclosing Confidential Information to underwriters and financial advisors (under an obligation of confidentiality) in connection with the public offering of securities, or (v) disclosing Confidential

Information that is reasonably determined is required to be disclosed by the Receiving Party (to comply with applicable securities or other laws) to public investors or governmental agencies in connection with the public offering of securities, provided that in all of the above cases, the Party disclosing Confidential Information of the Disclosing Party shall use all reasonable efforts to provide prior written notice of such disclosure to the Disclosing Party and to take reasonable and lawful actions to avoid or limit such disclosure or to assist the Disclosing Party in avoiding or limiting such disclosure. Further, either Party may also disclose the existence and terms of this Agreement to its attorneys and advisors, to potential acquirors in connection with a potential Change of Control or Sale of the Field Business and to existing and potential investors or lenders of such Party, as a part of their due diligence investigations, or to potential permitted assignees, in each case under an agreement to keep the terms of this Agreement confidential under terms of confidentiality and non-use substantially similar to the terms contained in this Agreement.

Subject to Section 12.6 and except as required pursuant to law or regulation, the following provisions shall apply to the Parties with respect to all publications, presentations and other public disseminations of any information relating to Products or to Development, manufacturing, or Commercialization performed pursuant to the Agreement:

          (a) The Party desiring to publish, present or otherwise publicly disseminate such information (the “Publishing Party”) shall provide the other Party with a copy of any proposed publication, presentation or other public dissemination at least forty-five (45) days prior to submission for publication, presentation or other public dissemination so as to provide such other Party an opportunity to recommend any changes it reasonably believes are necessary to preserve the Confidential Information belonging in whole or in part to such other Party or to preserve such other Party’s ability to obtain a patent or patents Covering any invention. The incorporation of such recommended changes shall not be unreasonably refused.

          (b) If such other Party provides written notice (“Notice”) to the Publishing Party within thirty (30) days of receipt of the copy of the proposed publication, presentation or other public dissemination that such publication, presentation or other public dissemination in its reasonable judgment (i) discloses information about an invention for which the other Party desires patent protection or (ii) discloses Confidential Information of the other Party, the Publishing Party shall prevent such publication or delay such publication, presentation or other dissemination until the Parties have agreed on mutually acceptable modifications thereto so as not to prejudice the other Party’s right to obtain a patent and not to disclose the other Party’s Confidential Information. In the case of inventions, a delay shall be for a period reasonably sufficient to permit the timely preparation and filing of a patent application(s).

     12.6 Publicity. The Parties agree that the public announcement of the execution of this Agreement shall be substantially in the form of the press release attached as Schedule 12.6 (the “Joint Press Release”). Neither Party shall issue any other news release or make any other

public announcement, written or oral, relating to this Agreement, including its terms, or the Products or potential Future Products, without the prior approval of the other Party, except solely to the extent a Party is advised by its legal counsel that the same is required by law or as otherwise permitted pursuant to Section 12.3; provided, however, the contents of any such announcement or similar publicity that has been previously reviewed and approved by the reviewing Party can be re-released by either Party without a requirement for re-approval. Each Party shall limit public disclosure of the financial terms set forth in this Agreement to the minimum extent required by law (by, for example, requesting confidential treatment of such terms in documents required to be filed with the US Securities and Exchange Commission); provided, however, the Parties may, after any required public disclosure for compliance with any applicable law, including securities laws, reference such financial terms in news releases or oral statements without seeking approval from the other Party.

     14.1 By Acura. Acura shall defend, indemnify and hold harmless King and its Affiliates and each of their officers, directors, shareholders, employees, successors and assigns (collectively, “King Indemnitees”) from and against all claims, charges, complaints, actions, suits, proceedings, hearings, investigations and demands (“Claims”) of Third Parties, and all associated Losses, to the extent arising out of (a) the Development, use, manufacture or Commercialization of Products outside the Territory by or under authority of Acura (other than by King, its Affiliates or sublicensees pursuant to the licenses granted hereunder), (b) the Development, use, manufacture or Commercialization by or under authority of Acura (other than by King, its Affiliates or sublicensees pursuant to the licenses granted hereunder) of any products with respect to which Acura has exercised any rights under Section 5.3(a), (c) any breach by Acura of any representation, warranty, covenant or obligation given in this Agreement, or (d) the gross negligence or willful misconduct of Acura in the performance of its obligations hereunder; provided, however, that in all cases referred to in this Section 14.1, Acura shall not be liable to indemnify any King Indemnitee for any Losses to the extent that King is obligated to indemnify an Acura Indemnitee for such Losses pursuant to Section 14.2.

     14.2 By King. King shall defend, indemnify and hold harmless Acura and its Affiliates and each of their officers, directors, shareholders, employees, successors and assigns (collectively, “Acura Indemnitees”) from and against all Claims of Third Parties, and all associated Losses, to the extent arising out of (a) the Development, use, manufacture or Commercialization of Products in the Territory, (b) the Development, use or manufacture by King or its Affiliates or permitted sublicensees of Products outside the Territory, (c) any breach by King or any of its Affiliates of any representation or warranty, covenant, or obligation given in this Agreement or (d) the gross negligence or willful misconduct of King or any of its Affiliates in the performance of its obligations hereunder; provided, however, that in all cases referred to in this Section 14.2, King shall not be liable to indemnify any Acura Indemnitee for any Losses to the extent that Acura is obligated to indemnify a King Indemnitee for such Losses pursuant to Section 14.1.

     14.3 Procedure for Indemnification.

          (a) Notice. Each Party will notify promptly the other if it becomes aware of a Claim (actual or potential) by any Third Party (a “Third Party Claim”) for which indemnification may be sought by that Party and will give such information with respect thereto as the other Party shall reasonably request. If any proceeding (including any governmental investigation) is instituted involving any Party for which such Party may seek an indemnity under Section 14.1 or Section 14.2 (the “Indemnified Party”), the Indemnified Party shall not make any admission or statement concerning such Third Party Claim, but shall promptly notify the other Party (the “Indemnifying Party”) orally and in writing and the Indemnifying Party and Indemnified Party shall meet to discuss how to respond to any Third Party Claims that are the subject matter of such proceeding. The Indemnifying Party shall not be obligated to indemnify the Indemnified Party to the extent any admission or statement made by the Indemnified Party or any failure by such Party to notify the Indemnifying Party of the Claim materially prejudices the defense of such Claim.

          (b) Defense of Claim. The following provisions shall apply to any Claim to which a Party is entitled to indemnification from the other Party under this Article 14. If the Indemnifying Party elects to defend or, if local procedural rules or laws do not permit the same, elects to control the defense of a Third Party Claim, it shall be entitled to do so provided it gives notice to the Indemnified Party of its intention to do so within forty-five (45) days after the receipt of the written notice from the Indemnified Party of the potentially indemnifiable Third Party Claim (the “Litigation Condition”). Subject to compliance with the Litigation Condition, the Indemnifying Party shall retain counsel reasonably acceptable to the Indemnified Party (such acceptance not to be unreasonably withheld, refused, conditioned or delayed) to represent the Indemnified Party and shall pay the fees and expenses of such counsel related to such proceeding. In any such proceeding, the Indemnified Party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of the Indemnified Party. The Indemnified Party shall not settle any Claim for which it is seeking indemnification without the prior consent of the Indemnifying Party which consent shall not be unreasonably withheld, refused, conditioned or delayed. The Indemnified Party shall, if requested by the Indemnifying Party, cooperate in all reasonable respects in the defense of such Claim that is being managed and/or controlled by the Indemnifying Party. The Indemnifying Party shall not,

without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, refused, conditioned or delayed), effect any settlement of any pending or threatened proceeding in which the Indemnified Party is, or based on the same set of facts could have been, a party and indemnity could have been sought hereunder by the Indemnified Party, unless such settlement includes an unconditional release of the Indemnified Party from all liability on Claims that are the subject matter of such proceeding. If the Litigation Condition is not met, then neither Party shall have the right to control the defense of such Third Party Claim and the Parties shall cooperate in and be consulted on the material aspects of such defense at each Party’s own expense; provided that if the Indemnifying Party does not satisfy the Litigation Condition, the Indemnifying Party may at any subsequent time during the pendency of the relevant Third Party Claim irrevocably elect, if permitted by local procedural rules or laws, to defend and/or to control the defense of the relevant Third Party Claim so long as the Indemnifying Party also agrees to pay the reasonable fees and costs incurred by the Indemnified Party in relation to the defense of such Third Party Claim from the inception of the Third Party Claim until the date the Indemnifying Party assumes the defense or control thereof.

     14.4 Assumption of Defense. Notwithstanding anything to the contrary contained herein, an Indemnified Party shall be entitled to assume the defense of any Third Party Claim with respect to the Indemnified Party, upon written notice to the Indemnifying Party pursuant to this Section 14.4, in which case the Indemnifying Party shall be relieved of liability under Section 14.1 or Section 14.2, as applicable, solely for such Third Party Claim and related Losses.

     14.5 No Consequential or Punitive Damages. NEITHER PARTY HERETO WILL BE LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, PUNITIVE OR MULTIPLE DAMAGES ARISING OUT OF THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, OR FOR LOST PROFITS ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES. NOTHING IN THIS SECTION 14.5 IS INTENDED TO LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY PURSUANT TO SECTIONS 14.1 AND 14.2 WITH RESPECT TO THIRD PARTY CLAIMS.

     14.6 Insurance. Each Party shall maintain product liability insurance for clinical trials performed by such Party pursuant to this Agreement and King shall also maintain product liability insurance for commercial sales of Products pursuant to this Agreement, in each case to support the indemnity provided to the other Party pursuant to this Agreement, in such amounts customarily maintained with respect to its other products and which is reasonable and customary in the pharmaceutical industry for companies of comparable size and activities. Such insurance policies shall remain in effect throughout the Term and for the period of time for which either Party has indemnification obligations following termination of this Agreement and shall not be cancelled or subject to a reduction of coverage without the prior written authorization of the other Party. Upon request by the other Party, a Party shall furnish certificates of insurance for all of the above noted policies. Each insurance policy that is required under this Section shall be obtained from an insurance carrier with an A.M. Best rating of at least A-VII. King shall be entitled to arrange coverage provided under this Section 14.6 by means of self-insurance and in such event shall promptly notify Acura.

ARTICLE 15
HSR

     15.1 HSR. Promptly following the Execution Date, King (or its Affiliates) and Acura (or its Affiliates) shall use Commercially Reasonable Efforts to take (i) all actions necessary to make the filing required under the HSR Act and (ii) reply at the earliest practicable date to any requests for information received from the Federal Trade Commission (“FTC”) or Antitrust Division of the U.S. Department of Justice (“DoJ”) pursuant to the HSR Act. The Parties shall, to the extent reasonably practicable, consult with one another prior to making any filings, responses to inquiries, or other contacts with the FTC or DoJ concerning the transactions contemplated hereby. Each Party shall bear its own expenses in connection with activities under this Article 15, except that King shall be responsible for the fee due to the FTC in respect of such filing.

ARTICLE 16
TERM AND TERMINATION

     16.1 Term. The Term shall commence on the Effective Date and expire, unless earlier terminated upon the mutual written agreement of the Parties or in accordance with the provisions of this Article 16, on the date of expiration of all royalty and other payment obligations (the “Expiration Date”) under this Agreement. Upon the Expiration Date, the licenses granted to King by Acura, shall become fully paid-up and irrevocable, subject to any obligations which have accrued prior to the Expiration Date.

     16.2 Termination Prior to Closing. In the event the Effective Date has not occurred prior to [***] either Party may terminate this Agreement in its entirety immediately upon giving notice to the other Party.

     16.3 Termination by King. King may at any time after [***] terminate this Agreement in its entirety or with respect to any Product, without cause, by giving Acura after such date no less than twelve (12) months advance written notice of such termination. In addition, King may terminate this Agreement in its entirety if Regulatory Approval of the NDA for Product A is not received prior to [***] (provided such failure to receive Regulatory Approval by such date is not caused by a clearly defined action or omission of King) and such termination shall be effective upon King giving written notice of such termination to Acura following such date. Further, King may terminate this Agreement with respect to a Product with respect to a country if Regulatory Approval for such Product is withdrawn by a Regulatory Authority in such country and such termination shall be effective upon King giving written notice of such termination to Acura following such withdrawal.

     16.4 Termination by Acura. Acura may terminate this Agreement with regards to a Product in the United States in the event that such Product is not commercially launched by King, an Affiliate of King, or a sublicensee of King in the United States within one hundred twenty (120) days after receipt of Regulatory Approval of such Product in the United States.

     16.5 Termination for Breach or Bankruptcy.

          (a) Each Party (the “Non-Breaching Party”) shall be entitled to terminate this Agreement on a Product-by-Product, country-by-country basis, by written notice to the other Party (the “Breaching Party”) in the event that the Breaching Party is materially in default of any of its material obligations hereunder relating to such Product and such country and fails to remedy such default within sixty (60) days (or, in the case of payment defaults, within thirty (30)) days after provision of written notice thereof by the Non-Breaching Party identifying the alleged breach in reasonable detail.

          (b) The effective date of termination of this Agreement under this Section 16.5 for an unremedied material breach of a material obligation shall be the date sixty (60) days (or, in the case of an unremedied payment default, thirty (30) days) after provision of written notice thereof by the Non-Breaching Party.

          (c) This Agreement may be terminated by a Party upon written notice to the other in the event that (i) the other Party shall make an assignment for the benefit of its creditors, file a petition in bankruptcy, petition or apply to any tribunal for the appointment of custodian, receiver or any trustee for it or a substantial part of its assets, or shall commence any proceeding under any bankruptcy, reorganization, arrangement, readjustment of debt, dissolution or liquidation law or statute of any jurisdiction, whether now or hereafter in effect; or (ii) if there shall have been filed against the other Party any such bona fide petition or application, or any such proceeding shall have been commenced against it, in which an order for relief is entered or which remains undismissed for a period of ninety (90) days or more; or (iii) if the other Party by any act or omission shall indicate its consent to, approval of or acquiescence in any such petition, application or proceeding or order for relief or the appointment of a custodian, receiver or trustee for it or any substantial part of its assets, or shall suffer any such custodianship, receivership or trusteeship to continue undischarged for a period of ninety (90) days or more; or (iv) anything analogous to any of the foregoing occurs in any applicable jurisdiction. Termination shall be effective upon the date specified in such notice.

     16.6 Patent Challenge. Acura will be permitted to terminate this Agreement by written notice effective upon receipt if King or its Affiliates (other than an Affiliate conducting such action prior to a Change of Control of such Affiliate), directly or indirectly through assistance granted to a Third Party, commence any interference or opposition proceeding, challenge the validity or enforceability of, or oppose any extension of or the grant of a supplementary protection certificate with respect to, any Aversion Patent Rights (each such action, a “Patent Challenge”). King will include provisions in all agreements granting sublicenses of King’s rights hereunder providing that if the sublicensee or its Affiliates undertake a Patent Challenge with respect to any Aversion Patent Rights under which the sublicensee is sublicensed, King will be permitted to terminate such sublicense agreement. If a sublicensee of King (or an Affiliate of such sublicensee) undertakes a Patent Challenge of any such Aversion Patent Right under which such sublicensee is sublicensed, then King upon receipt of notice from Acura of such Patent Challenge will terminate the applicable sublicense agreement. If King fails to so terminate such sublicense agreement, Acura may terminate King’s right to sublicense in the countr(ies) covered by such sublicense agreement and any sublicenses previously granted in such

countr(ies) shall automatically terminate. In connection with such sublicense termination, King shall cooperate with Acura’s reasonable requests to cause such a terminated sublicensee to discontinue activities with respect to the Product in such countr(ies).

     16.7 Consequences of Termination.

          (a) Termination by either Party under Section 16.2. In the event this Agreement is terminated in its entirety by either Party under Section 16.2, then, notwithstanding Section 16.9, any and all rights, obligations and covenants of the Parties set forth in Article 13 shall terminate in their entirety.

          (b) Termination by King at Will or by Acura for King’s Breach or Bankruptcy or a Patent Challenge. Upon any termination of this Agreement by King pursuant to Section 16.3 or by Acura pursuant to Section 16.4, 16.5 or 16.6:

               (i) Any and all licenses granted by Acura to King under this Agreement shall terminate in their entirety or with respect to the Product(s) and country(ies) to which the termination relates, as the case may be, on the effective date of such termination, and the licenses granted by King to Acura under this Agreement shall continue;

               (ii) King shall, upon Acura’s written request, assign and transfer to Acura, or its Affiliates as requested by Acura, at no expense to Acura or its Affiliates, and free of any liens, pledges, security interests and other financial encumbrances including those incurred in the Commercialization of the Product, all of King’s right, title and interest in and to the trademarks (including any goodwill associated therewith) which are solely used in connection with Commercialization of Product(s) (for the avoidance of doubt, excluding the King housemark as well as any other trademarks used in connection with any other product(s) or in connection with King’s business in the Field generally), any registrations and design patents for any of the foregoing and any internet domain name registrations for such trademarks and slogans, all regulatory filings (such as INDs and NDAs), other Regulatory Approvals, and clinical trial agreements (to the extent assignable and not cancelled) for such Product(s) in such country(ies), and all data, including clinical data, materials and information of any kind or nature whatsoever, in King’s possession or in the possession of its Affiliates or its or their respective agents related to such Product(s) in such country(ies) developed under this Agreement. All such filings, approvals and data transferred to Acura pursuant to this Section 16.7 shall be deemed to be Acura Confidential Information;

               (iii) If King is responsible for the commercial supply of Product at the time of termination, then King shall supply, or cause to be supplied, to Acura, upon Acura’s written request, Acura’s or its licensee’s commercial requirements of Product, pursuant to a supply agreement to be negotiated in good faith by the Parties on commercially reasonable terms, provided that (1) any and all or part of King’s remaining supply and inventory of Product shall be provided to Acura at King’s fully burdened cost of goods plus [***] (2) any additional requirements for Product shall be supplied to Acura or its licensee at King’s fully burdened cost of goods plus [***] (3) King’s supply obligation shall not continue for more than twenty-four (24) months after the termination of this Agreement, (4) King shall maintain the same quality

and specifications for manufacturing Product as immediately prior to notice of termination, and (5) Acura shall effect a transfer as soon as practicable of Product manufacturing activities from King to another supplier. King shall also provide Acura or its designated supplier, at Acura’s cost, reasonable assistance and cooperation in providing a manufacturing transfer package with the goal of enabling Acura or such designated supplier to manufacture the Product; and

               (iv) Other than in Section 16.7(b)(iii) above, King shall cease Developing, manufacturing, and Commercializing such Products under this Agreement and the licenses granted to King hereunder with respect to such Products shall terminate.

          (c) Termination due to Acura’s Breach or Bankruptcy or Termination by Either Party Prior to Closing. Upon any termination of this Agreement by King with respect to a Product or country under Section 16.5(a) or termination of this Agreement in its entirety by King pursuant to Sections 16.5(a) or 16.5(c) or a termination by either Party pursuant to Section 16.2, any and all licenses granted by Acura to King under this Agreement shall terminate in their entirety or with respect to the Product(s) and country(ies) to which the termination relates, as the case may be, on the effective date of such termination.

          (d) Royalty and Payment Obligations. Termination of this Agreement by either Party for any reason will not release King from any obligation to pay royalties or milestones or to make any payments to Acura which were accrued prior to the effective date of termination (including for milestone events achieved under Article 8, prior to the date of termination) or that relate to Product(s) or country/countries to which such termination does not relate. However, termination of this Agreement by either Party for any reason will release King from any obligation to pay royalties or make any payments to Acura which would have otherwise become accrued after the effective date of termination (provided that King shall be obligated to pay royalties after the effective date of termination for Products sold prior to such effective date).

          (e) Non-Exclusive Remedy for Breach. The provisions of this Section 16.7 are not intended to be exclusive and are without prejudice to the rights of the Parties to seek any other rights and remedies that they may have under this Agreement, at law or in equity or otherwise.

     16.8 Bankruptcy. Any licenses or rights granted under or pursuant to this Agreement by Acura to King are, and shall otherwise be deemed to be, for purposes of Section 365(n) of Title 11, US Code (the “Bankruptcy Code”), licenses of rights to “intellectual property” as defined under Section 101(35A) of the Bankruptcy Code. The Parties agree that during the Term, King, as a licensee of rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code, subject to the continued performance of its obligations under this Agreement.

     16.9 Survival of Obligations. Subject to Section 16.7(a), Sections 11.1, 11.2, 13.1 (for the periods of time set forth therein), 13.2, 13.3, 13.4, 16.7, 16.8, 16.9 and Articles 10, 12, 14 and 17 and any definitions used in any such Section or Article shall survive the termination of this Agreement in its entirety. Except for obligations which clearly are not intended to continue

in respect of a partial termination pursuant to Section 16 (including the applicable diligence obligation), with respect to the country or Product terminated, all obligations in this Agreement shall survive such partial termination.

FOR IMMEDIATE RELEASE

KING PHARMACEUTICALS AND ACURA PHARMACEUTICALS ENTER
AGREEMENT TO DEVELOP AND COMMERCIALIZE IMMEDIATE RELEASE PAIN
MEDICINES UTILIZING ACURA’S AVERSION^® (ABUSE-DETERRENT)
TECHNOLOGY

Transaction Expands King’s Near-term Pipeline of Products
Designed to Deter Common Methods of Opioid Abuse

BRISTOL, TENNESSEE and PALATINE, ILLINOIS, October 31, 2007 – King Pharmaceuticals, Inc. (NYSE: KG) and Acura Pharmaceuticals, Inc. (OTC.BB-ACUR) announced today that the companies have entered into a License, Development and Commercialization Agreement (the “Agreement”) for the United States, Canada, and Mexico (the “Territory”) encompassing a potentially wide range of opioid analgesic products utilizing Acura’s patented Aversion^® (abuse-deterrent) Technology platform. The companies have initially targeted development and commercialization of four immediate release opioid analgesic products, including ACUROX™ Tablets (oxycodone HCl, niacin, and a unique combination of other ingredients), formerly known as OxyADF, for treating moderate to severe acute pain.

▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇▇, Chairman, President and CEO of King, stated, “This transaction demonstrates our commitment to building on our strengths in specialty markets where we have a strong presence and existing capabilities. We are excited about partnering with Acura, which directly aligns with our recently announced emphasis on King’s neuroscience and hospital/acute care platforms, particularly our growing pain management franchise.”

▇▇▇▇ ▇▇▇▇▇▇▇, President and CEO of Acura said, “We believe King’s abuse-deterrent analgesic brand product pipeline and neuroscience expertise perfectly complement our Aversion^® Technology platform. King is clearly leading the pharmaceutical industry with its understanding of the opportunities and challenges relating to the market for products designed to discourage prescription drug abuse.”

▇▇. ▇▇▇▇▇▇▇ added, “We look forward to working closely with King to bring innovative immediate release opioid analgesic products to market utilizing our Aversion^® (abuse-deterrent) Technology. Discouraging prescription drug abuse benefits patients, healthcare providers, third

[Schedule 12.6 to License, Development and Commercialization Agreement]

party payors, and society as a whole, while at the same time we expect to create substantial value for King and Acura shareholders.”

Dr. ▇▇▇▇ ▇▇▇▇▇▇, Chief Science Officer of King, commented, “Opioid analgesics play a very important role in the effective management of moderate to severe pain. However, abuse and misuse of these medicines represents a major area of concern among physicians, pharmacists, patients, and the health-care sector. At King, we are committed to addressing this important public health issue and the needs of our customers by offering pain medicines that are proven effective and incorporate safe and appropriate means to discourage abuse and misuse.”

▇▇. ▇▇▇▇▇▇ added, “We believe Acura and our long-established partner, Pain Therapeutics, have developed unique platforms designed to address the challenges related to abuse and misuse of immediate release and long-acting pain medicines. Acura’s innovative and proprietary Aversion^® Technology has the potential to significantly reduce common methods of abuse associated with immediate release opioids used for the treatment of acute pain. Similarly, REMOXY^™ (long acting oral oxycodone) and other long-acting opioids that we are jointly developing with Pain Therapeutics utilizing Durect Corporation’s SABER^™ formulation technology have significant potential to deter common methods of abuse associated with long-acting opioids used for the treatment of chronic pain.”

“Our alliance with Acura will help further address this growing opportunity and adds considerable strength to King’s pipeline, allowing for the development of multiple future medicines,” concluded ▇▇. ▇▇▇▇▇▇.

About the License, Development and Commercialization Agreement

The Agreement provides King with an exclusive license in the Territory for ACUROX™ Tablets (formerly OxyADF) and another undisclosed opioid product utilizing Acura’s Aversion^® Technology. In addition, the Agreement provides King with an option to license in the Territory all future opioid analgesic products developed utilizing Acura’s Aversion^® Technology.

Under the terms of the Agreement, King will make an upfront cash payment to Acura of $30 million. Depending on the achievement of certain development and regulatory milestones, King could also make additional cash payments to Acura of up to $28 million relating to ACUROX™ Tablets and similar amounts with respect to each subsequent Aversion^® Technology product developed under the Agreement. King will reimburse Acura for all research and development expenses incurred beginning from September 19, 2007 for ACUROX™ Tablets and all research and development expenses related to future products after King’s exercise of its option to an exclusive license for each future product. King will record net sales of all products and pay Acura a royalty ranging from 5% to 25% based on the level of combined annual net sales for all products subject to the Agreement. King will also make a one-time cash payment to Acura of $50 million in the first year in which the combined annual net sales of all products exceed $750 million.

King and Acura will form a joint steering committee to coordinate development and commercialization strategies. With King’s oversight, Acura will conduct all ACUROX™ Tablet

[Schedule 12.6 to License, Development and Commercialization Agreement]

development activities through approval of a New Drug Application (“NDA”) and thereafter King will commercialize ACUROX™ in the U.S. With respect to all other products subject to the Agreement, King will be responsible for development and regulatory activities following either acceptance of an Investigational New Drug Application by the U.S. Food and Drug Administration (“FDA”) or Acura’s demonstration of certain stability and pharmacokinetic characteristics for each future product. All products developed pursuant to the Agreement will be manufactured by King or a third party contract manufacturer under the direction of King. Subject to the Agreement, King will have final decision making authority with respect to all development and commercialization activities for all products licensed.

The Agreement closing is subject to antitrust review under the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act.

The United States Patent and Trademark Office has granted U.S. Patent No. 7,201,920 relating to Acura’s Aversion^® (abuse-deterrent) Technology, which expires on March 16, 2025.

About ACUROX™ Tablets

ACUROX™ (formerly OxyADF) is an orally administered immediate release tablet containing oxycodone HCl as an active analgesic ingredient, niacin as an active ingredient in subtherapeutic amounts, and a unique combination of other ingredients. ACUROX™ Tablets are intended to effectively treat moderate to moderately severe pain while discouraging the three most common methods of prescription drug abuse including (i) intravenous injection of dissolved tablets, (ii) nasal snorting of crushed tablets and (iii) intentional swallowing of excessive numbers of tablets.

Earlier this year, Acura reached agreement with the FDA on a Special Protocol Assessment for a pivotal Phase 3 clinical trial evaluating ACUROX™ Tablets. This clinical trial is a randomized, double-blind, placebo-controlled, multi-center, repeat-dose study evaluating the safety and efficacy of ACUROX™ Tablets for the treatment of acute, moderate to moderately severe postoperative pain. The 3-arm clinical trial compares two dose levels of ACUROX™ Tablets to placebo and is targeted to enroll 135 patients per arm (approximately 405 patients in total). Study medication will be administered to patients every six hours for 48 hours following the onset of moderate to severe pain following bunionectomy surgery. This pivotal Phase 3 clinical trial began enrolling patients in September with a final study report expected in the second half of 2008.
