Notwithstanding the above, if the nonconformity of the API could not reasonably have been ascertained by Company upon reasonable inspection and analysis of the API, then the [***] period referred to herein shall not apply, provided that Company notifies Halozyme promptly upon discovery of such nonconformity (but in no event later than [***] from the date of the discovery). Halozyme shall use [***] to cure such rejection or replace such nonconforming shipment of API, or portion thereof, within [***] after receipt of notice of rejection thereof. 7.4.4 Company’s grounds for rejection shall be conclusive unless Halozyme notifies Company within [***] of receipt by Halozyme of the notice of rejection that it disagrees with such grounds. In the event of such a notice by Halozyme, representative samples of the batch of API in question shall be submitted to a mutually acceptable independent laboratory or consultant (if not a laboratory analysis issue) for analysis or review, the costs of which shall be paid by the Party that is determined by the independent laboratory or consultant to have been incorrect in its determination of whether the applicable API should be rejected. 7.5 API Price.

Halozyme shall invoice Company for all API upon shipment in accordance with this Article 7, and Company shall pay each such invoices within [***]. 7.6 LIMITATION OF LIABILITY. HALOZYME’S LIABILITY TO COMPANY, AND COMPANY’S REMEDY, FOR ANY FAILURE OF THE WARRANTIES SET FORTH IN SECTION 7.7 SHALL BE, AT HALOZYME’S OPTION, [***].

CONFIDENTIALITY. 9.1 Confidentiality. With respect to any Confidential Information disclosed by a Party (the “Disclosing Party”) to the other Party (the “Receiving Party”) hereunder, the Receiving Party shall, and shall ensure that any of its Affiliates and Third Parties authorized to have such information, maintain in confidence the Confidential Information of the Disclosing Party and use the Disclosing Party’s Confidential Information for the sole and limited purpose of fulfilling its obligations under this Agreement. During the term of this Agreement and for a period that is the longer of: (i) [***] following the expiration or earlier termination of this Agreement, and (ii) in the case of Confidential Information that is a trade secret, until such Confidential Information ceases to be a trade secret. To the extent that disclosure to any person is authorized by this Agreement (e.g., an Affiliate, a sublicensee, etc.) and such person has a need to know it, prior to disclosure, a Party shall obtain written agreement of such person to hold in confidence and not disclose, use or grant the use of the Confidential Information of the other Party except as expressly permitted under this Agreement, together with other relevant terms limiting disclosure that are no less restrictive than those in this Agreement regarding disclosure and use of Confidential Information. Each Party shall notify the other Party promptly upon discovery of any unauthorized use or disclosure of the other Party’s Confidential Information. A Disclosing Party’s Confidential Information is owned by such Party, and subject to Article 3 of this Agreement, no license or other rights to the Disclosing Party’s Confidential Information are granted or implied hereby. Notwithstanding Article 12, the Parties agree that a breach of any of the obligations in this Article 9 may result in irreparable and continuing damage to the Disclosing Party for which there is no adequate remedy at law, and the Disclosing Party may therefore seek injunctive relief and/or a decree of specific performance, in addition to such other legal and/or equitable remedies as may be available. 9.2 Permitted Disclosures. Notwithstanding the obligations of confidentiality and non-use set forth in Section 9.1 above, a Receiving Party may provide Confidential Information disclosed to it and disclose the existence and terms and conditions of this Agreement, in each case, to the extent such disclosure is: 9.2.1 to its Affiliates, sublicensees (as permitted under this Agreement), subcontractors, consultants, and their employees, directors, agents, consultants, or advisors, in each case, to the extent necessary for the potential or actual performance of its obligations or exercise of its rights under this Agreement, in each case, who are under an obligation of confidentiality with respect to such information that is no less stringent than the terms and conditions of this Article 9; provided that the foregoing shall in no way be deemed to limit or supersede the obligations to implement and enforce Firewalls where required under this Agreement;

30 9.2.2 to the Regulatory Authorities in connection with any filing, application or request for Regulatory Approval in accordance with the terms of this Agreement; provided that reasonable measures shall be taken to assure confidential treatment of such Confidential Information to the extent practicable and consistent with applicable law; 9.2.3 made in connection with the prosecution or maintenance of [***] in an effort to secure, maintain, defend or enforce Patent Rights, as contemplated by this Agreement, or, with respect to such activities only, otherwise with the prior written consent of the Disclosing Party’s intellectual property counsel; 9.2.4 to bring or defend litigation and to enforce Patent Rights in connection with the Receiving Party’s rights and obligations pursuant to this Agreement; 9.2.5 subject to the last paragraph of this Section 9.2, required to be disclosed by applicable law, including by the rules or regulations of the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States or of any stock exchange or listing entity; and 9.2.6 (a) with respect to the terms and conditions of this Agreement, any bona fide [***], and (b) with respect to any other Confidential Information of the other Party, any bona fide [***], provided that any entity or individual receiving Confidential Information under clause (a) or (b) has a need to know such information and is under obligations of confidentiality and non-use with respect to such information that are no less stringent than the terms and conditions of this Article 9 (but of duration customary in confidentiality agreements entered into for a similar purpose). If a Party, after consultation with counsel, determines it is required by law to disclose Confidential Information of the other Party that is subject to the confidentiality or non- disclosure provisions of Section 9.1, then such Party will promptly inform the other Party of the disclosure that is being sought (and to the extent possible at least [***] notice) in order to provide the other Party an opportunity to challenge or limit the disclosure and will reasonably cooperate with the other Party to do so. In the event that no such protective order or other remedy is obtained, or the Disclosing Party waives compliance with certain terms of this Article 9, then the Receiving Party will furnish only that portion of Confidential Information that the Receiving Party is advised by counsel is legally required to be disclosed. Notwithstanding Section 9.1, Confidential Information that is permitted or required to be disclosed will remain otherwise subject to the confidentiality and non-use provisions of this Article 9. If either Party concludes based on the reasonable opinion of counsel that a copy of this Agreement must be filed with the United States Securities and Exchange Commission or similar regulatory agency in a country other than the United States, such Party will, within a reasonable time prior to any such filing (and to the extent possible at least [***] prior to any such filing), provide the other Party with a copy of this Agreement showing any provisions hereof as to which the Party proposes to request confidential treatment, will provide the other Party with an opportunity to comment on any such proposed redactions and to suggest additional redactions, and will take such Party’s reasonable comments into consideration (and shall not unreasonably object to any such redactions) before filing such copy of this Agreement and use reasonable efforts to have

31 terms identified by such other Party afforded confidential treatment by the applicable regulatory agency. 9.2.7 Notwithstanding the foregoing, in no event shall Company disclose, or authorize the disclosure of, any Confidential Information of Halozyme or its Affiliates, or this Agreement or any terms contained herein, to [***], without the prior written consent of Halozyme. 9.3 Publications. 9.3.1 Prior to the Regulatory Approval Date, either Party may publish the results of its research and/or development under this Agreement in order to obtain recognition within the scientific community and to advance the state of scientific knowledge, and such publication shall be subject to the following procedures. If a Party desires to make any such publication (including any oral disclosure made without obligation of confidentiality), such Party shall provide the other Party with a copy of the proposed written publication at least [***] prior to submission for publication, or an outline of such oral disclosure at least [***] prior to presentation. At the reasonable request of the other Party, the publishing Party shall remove any Confidential Information of the other Party therefrom. The other Party additionally shall have the right (a) to propose modifications to the publication for intellectual property reasons, (b) to request a reasonable delay in publication in order to protect patentable information, and (c) propose alternative wording for scientific or clinical clarification. If the other Party requests such a delay, the publishing Party shall delay submission or presentation of the publication and shall not proceed with the written publication or the presentation without the prior written consent of the other Party, such consent not to be unreasonably withheld. 9.3.2 After the Regulatory Approval Date, Company may publish the results of its research and/or development under this Agreement in order to obtain recognition within the scientific community and to advance the state of scientific knowledge, and such publication shall be subject to the following procedures. If Company desires to make any such publication (including any oral disclosure made without obligation of confidentiality), Company shall provide Halozyme with a copy of the proposed written publication at least [***] prior to submission to a journal, or an outline of such oral disclosure at least [***] prior to presentation. At the reasonable request of Halozyme, Company shall remove any Confidential Information of Halozyme therefrom. Halozyme additionally shall have the right (a) to propose modifications to the publication for patent reasons, and (b) to request a reasonable delay in publication in order to protect patentable information, which request Company will consider in good faith. If Halozyme requests such a delay, Company shall delay submission or presentation of the publication for a period of up to [***] to enable Halozyme to prepare and file applicable patent applications. Upon the expiration of such [***] period, subject to the requirement to remove any Confidential Information of Halozyme, Company shall be free to proceed with the written publication or the presentation, respectively, unless Halozyme has requested the delay described above. 9.3.3 Halozyme shall not publish any studies, clinical trials or results thereof regarding [***] and only then with the prior written consent of Company.

Company shall notify Halozyme at least [***] in advance of a XxxxxxxxXxxxxx.xxx or equivalent posting or change. 9.5 Public Announcements. On or after the Effective Date, the Parties will issue separate press releases regarding the signing of this Agreement, the form and substance of which shall be agreed to in writing by the Parties. Except (a) as set forth in the preceding sentence and (b) with respect to Company’s reporting obligations under applicable law, rule or regulation or the rules of a stock exchange on which the securities of Company are listed, neither Party shall issue any other public announcement, press release, or other public disclosure regarding this Agreement or its subject matter without the other Party’s prior written consent, except in accordance with Section 9.2. 10. INDEMNIFICATION AND INSURANCE. 10.1 By Company. Company shall indemnify and hold harmless Halozyme, its Affiliates, and their respective directors, officers, employees and agents (collectively, the “Halozyme Indemnitees”), from and against all losses, liabilities, damages and expenses, including reasonable attorneys’ fees and costs (collectively, “Liabilities”), resulting from any claims, demands, actions or other proceedings by any Third Party to the extent resulting from (a) the breach of any representation, warranty, covenant, or other obligation, by Company under this Agreement; (b) the use by Company, its sublicensees or their respective Affiliates of the Licensed IP Rights beyond the scope of the licenses granted herein; or (c) the manufacture, use, sale, marketing, handling or storage of Products by Company, its sublicensees or their respective Affiliates, customers or end-users, including any personal injury, death or illness; all of the foregoing except in the event and to the extent any Liability arises out of or results from (i) the negligence or willful misconduct of Halozyme or its Affiliates or (ii) matters within Halozyme’s indemnification obligations under Section 10.2. 10.2 By Halozyme. Halozyme shall indemnify and hold harmless Company, its Affiliates, and their respective directors, officers, employees and agents (collectively, the “Company Indemnitees”), from and against all Liabilities resulting from any claims, demands, actions or other proceedings by any Third Party to the extent resulting from (a) the breach of any representation, warranty, covenant, or other obligation by Halozyme under this Agreement; (b) the manufacture, use, sale, handling or storage of API by Halozyme (including any failure of API to conform to the product warranties set forth in Section 7.7); or (c) any allegation that Company’s use of the Licensed Marks in accordance with this Agreement infringes or violates the trademark rights of any Third Party; all of the foregoing except in the event and to the extent any Liability arises out of or results from (i) the negligence or willful misconduct of Company, its sublicensees or their respective Affiliates, or (ii) matters within Company’s indemnification obligations under Section 10.1. 10.3 Procedure. If a Party (the “Indemnitee”) intends to claim indemnification under this Article 10, it shall promptly notify the other Party (the “Indemnitor”) in writing of any

33 claim, demand, action or other proceeding for which the Indemnitee intends to claim such indemnification, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, to assume the defense thereof with counsel mutually satisfactory to the Parties; provided, however, that an Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitor, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between the Indemnitee and any other Party represented by such counsel in such proceeding. The obligations of this Article 10 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld or delayed unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve the Indemnitor of any obligation to the Indemnitee under this Article 10. The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any claim, demand, action or other proceeding covered by this Article 10. 10.4 Insurance. Each Party shall maintain insurance, including Commercial General Liability, Product Liability and, for clinical trials it sponsors, Clinical Trials Liability insurance and Workers Compensation and Employer’s Liability insurance, with respect to its activities under this Agreement regarding Products in such amount as such Party customarily maintains with respect to similar activities for its other products, but not less than the greater of (i) [***] each occurrence and aggregate for Commercial General Liability, Product Liability, and Clinical Trials Liability insurance in amounts compliant with local insurance regulations and [***] limit per accident /disease and a [***] disease policy limit Workers Compensation and Employer’s Liability or (ii) such amount as is reasonable and customary in the industry.

Each Party shall provide the other Party [***] notice of any material change, cancellation or non-renewal of any required insurance under this Agreement. In the event of a material change, cancellation, or non-renewal in coverage, each Party shall replace such coverage to comply with this Agreement so that there is no lapse of coverage for any time period. 11. TERM AND TERMINATION. 11.1 Term. This Agreement shall commence on the Effective Date and, unless earlier terminated pursuant to this Section 11, shall continue until the expiration of the last Royalty Term in the Territory for such Product (the “Term”). 11.2 Termination for Material Breach. If a Party believes that the other Party has materially breached this Agreement, the non-breaching Party may deliver written notice of such material breach to the other Party. If the breach is curable, the breaching Party will have [***] following its receipt of such written notice to cure such breach. If the breaching Party fails to cure such material breach within such [***] period or the breach is not subject to cure, then the non- breaching Party shall have the right to terminate this Agreement by providing written notice to the breaching Party, in which case, this Agreement will terminate on the date on which the breaching Party receives such written notice. Notwithstanding the foregoing, in the event that the allegedly

34 breaching Party disputes whether a material breach has occurred, or whether any such alleged material breach is cured, in each case, during the [***] cure period, then the allegedly breach Party will promptly refer such matter for resolution in accordance with the expedited dispute resolution process set forth in Section 12.2, the cure period will be tolled, and this Agreement will not be terminated as a result of such alleged breach, during the pendency of such dispute. 11.3 Termination for Convenience.

Upon the filing or institution of bankruptcy, reorganization, liquidation, or receivership proceedings, upon the appointment of a receiver or trustee over all or substantially all property, or upon an assignment of a substantial portion of the assets for the benefit of creditors by Halozyme, Halozyme agrees that Company, as licensee of such rights under this Agreement, will retain and may fully exercise all of its rights and elections under the U.S. Bankruptcy Code. Each Party acknowledges and agrees that “embodiments” of intellectual property within the meaning of Section 365(n) include laboratory notebooks, product samples and inventory, research studies and data, all Regulatory Approvals (and all applications for Regulatory Approval) and rights of reference therein, the Licensed IP Rights, results, and all information related to the Licensed IP Rights. If (i) a case under the U.S. Bankruptcy Code is commenced by or against Halozyme, (ii) this Agreement is rejected as provided in the U.S. Bankruptcy Code, and (iii) Company elects to retain its rights hereunder as provided in Section 365(n) of the U.S. Bankruptcy Code (which, for avoidance of doubt, shall be as such rights existed immediately before the commencement of such case, and solely for the duration of the Term), then Halozyme (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) will, upon written request of Company: (a) provide Company with a copy of all such intellectual property (including all embodiments thereof, to the extent protected by applicable non-bankruptcy law) held by Halozyme and such successors and assigns to the extent included in or comprising the Licensed IP Rights, immediately upon Company’s written request; and (b) not interfere with Company’s rights under this Agreement, or any agreement supplemental hereto, to such intellectual property (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity, to the extent provided in Section 365(n) of the U.S. Bankruptcy Code. In such event, the royalty payments shall be deemed “royalties” as defined under Section 365(n) of the U.S. Bankruptcy Code.

MISCELLANEOUS. 12.1 Governing Law; Escalation; Arbitration. This Agreement shall be governed in all respects by the laws of the State of New York, without regard to the conflicts of law principles thereof. The United Nations Convention of International Contracts on the Sale of Goods (the Vienna Convention) does not apply to this Agreement. If there is a dispute between the Parties under this Agreement that cannot be resolved by the alliance leaders, then the dispute shall be referred to a member of executive management to be designated by each Party for resolution. If the executives cannot resolve such matter within a period of [***] from the date on which such matter is referred to them, either Party may invoke the dispute resolution process herein. Except with respect to any action, suit or proceeding seeking specific performance or injunctive or interim, provisional or precautionary measures or other equitable relief or any matter expressly specified to be resolved in accordance with Section 12.2, each Party agrees that any controversy or claim in any way arising out of or relating to this Agreement shall be determined by a sole arbitrator in an arbitration administered by the International Centre for Dispute Resolution (hereinafter “ICDR” or the “Arbitration Center”), in accordance with its International Arbitration Rules in force at the time of the submission. The Parties grant special irrevocable power of attorney to the ICDR, so that, in accordance with the ICDR’s standard list selection process, it may appoint the arbitrator from among the members of the arbitration body of the Arbitration Center that have experience adjudicating disputes relating to pharmacology and intellectual property licensing. In the event no members have such experience, then it may appoint the arbitrator from among the members of the arbitration body of the Arbitration Center that have experience adjudicating disputes relating to intellectual property licensing. Prior to the appointment of the arbitrator by the Arbitration Center, each Party may veto up to five (5) members of the arbitration corps of the Arbitration Center without cause. The arbitrator is specifically empowered to resolve any matter related to their competence and/or jurisdiction. The place of the arbitration shall be in [***]. For all legal purposes, the Parties agree [***] that the arbitration shall be governed by the laws of [***]. Judgment upon any award(s) rendered in such arbitration will be binding. The Parties hereto irrevocably submit to the exclusive jurisdiction of any federal or state court located within [***] for enforcement of or challenge to any such award(s) rendered by an arbitrator pursuant to this Section, and each Party hereby irrevocably agrees that all claims in respect of such dispute, any suit, action, or proceeding related thereto, or any other action, suit or proceeding seeking specific performance or injunctive or interim, provisional or precautionary measures or other equitable relief, may, in each case, be heard and determined in such courts. The Parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the laying of venue or any such dispute brought in such court or any defense of inconvenient forum for the maintenance of such dispute. The arbitrator’s award shall include a determination of the prevailing Party’s reasonable legal fees and costs associated with any such arbitration to be reimbursed by the non-prevailing Party. To the extent any arbitration award is brought before a court for enforcement purposes, the Parties will waive trial by jury in any such proceeding. The Parties undertake to keep confidential all awards in their arbitration, together with all materials in the proceedings created for the purpose of the arbitration and all other

37 documents produced by another Party in the proceedings not otherwise in the public domain, except and to the extent that disclosure may be required of a Party by applicable law or to enforce or challenge an award in legal proceedings before a court or other judicial authority, in which case the Party disclosing such information shall, to the extent permissible under applicable law, give the other Party reasonable advance notice of such disclosure and use reasonable efforts to secure confidential treatment of such information (whether through protective order or otherwise). 12.2 Expedited Arbitration. In the event of any dispute as to whether a material breach of this Agreement has occurred, the Parties will submit to an expedited binding arbitration to resolve the dispute, which will be determined by arbitration administered by ICDR in accordance with its International Expedited Procedures. The place of the expedited arbitration shall be in [***]. For all legal purposes, the Parties agree [***] that the arbitration shall be governed by the laws of [***]. The Parties grant special irrevocable power of attorney to the ICDR, so that, in accordance with the ICDR’s standard list selection process, it may appoint the arbitrator from among the members of the arbitration body of the Arbitration Center that have sufficient experience adjudicating similar disputes relating to intellectual property licensing in connection with pharmaceutical and biologic products. 12.3 Waivers. The failure of any Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party. 12.4 Assignment. Neither this Agreement nor any right or obligation hereunder may be assigned or delegated, in whole or part, by either Party without the prior written consent of the other; except that either Party may assign this Agreement and its rights and obligations hereunder without the consent of the other Party, but with prompt notice of such assignment, to: (a) such Party’s Affiliate(s) (except with respect to Third Parties that become an Acquirer pursuant to a Change of Control, which is solely addressed in the following subsection (b) below), provided that, as between the Parties, such Party shall remain primarily liable for any acts or omissions of such Affiliate; (b) the Acquirer in connection with a Change of Control, or otherwise under a transaction under which this Agreement is assumed, or the successor or acquiring party in connection with a sale of all or substantially all of the assets of such Party or to which this Agreement relates (in which case, such Party shall assign this Agreement to such successor or acquiring party in connection with such sale of assets). Notwithstanding the foregoing, in no event shall Company assign this Agreement or its rights or obligations hereunder, in whole or in part, to [***]. Any Acquirer or permitted assignee shall assume all obligations of its assignor under this Agreement, and Company shall cause such Acquirer or permitted assignee to agree in writing to such assumption and to be bound by, and fully perform, the terms and conditions of this Agreement. Any purported assignment in violation of this Section 12.4 shall be void. 12.5 Change of Control. 12.5.1 Company shall provide Halozyme written notice of any Change of Control of Company promptly, but no later than [***], following the first public announcement of such Change of Control, which notice shall describe in reasonable detail the nature of the transaction and the identity of the Acquirer. If as of the closing date of such Change of Control transaction such Acquirer is [***], then the following shall apply: (i) Company shall implement

38 or cause its Acquirer to [***], and (ii) Company shall continue to comply with its obligations under this Agreement in full force and effect, or shall cause such Acquirer to comply with such obligations (if applicable, to the extent Acquirer succeeds Company). 12.5.2 Halozyme shall have the right, through a designated Third Party auditor reasonably acceptable to Company, to audit Company’s (and, as applicable, its Affiliates’) Firewall obligations under this Agreement for purposes of confirming compliance with the Firewalls, identifying any vulnerabilities or breaches and requiring Company (or its Affiliates) to promptly remediate any non-compliance identified by such audit. In connection with such audit, duly authorized representatives of Halozyme’s designated auditor may make an on-site visit to Company (or its Affiliate) for the purpose of conducting such audit. Halozyme may conduct such audits from time to time as reasonably necessary to confirm Company’s compliance with such Firewall requirements no more than once per calendar year or more frequently if Halozyme reasonably believes at any time that Company is not in compliance with such Firewall requirements; provided that if the auditor identifies a breach of the Firewall, Halozyme will be entitled to an additional audit within the same year to verify that appropriate action has been taken to remedy the breach of the Firewall. If the auditor identifies any breach of the Firewall, Halozyme and/or the auditor will notify Company, and Company will promptly (and will use reasonable efforts to ensure its Affiliates promptly) take all action necessary to remedy such breach, and will provide Halozyme with reasonable assurance that such action has been taken, at Company’s sole expense. 12.6 Independent Contractors. The relationship of the Parties hereto is that of independent contractors. The Parties hereto are not deemed to be agents, partners or joint venturers of the others for any purpose as a result of this Agreement or the transactions contemplated thereby. 12.7 Further Actions.

IN NO EVENT SHALL A PARTY BE LIABLE FOR SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 12.10 WILL LIMIT OR RESTRICT, AND THE FOREGOING LIMITATIONS SHALL NOT APPLY TO, THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY UNDER ARTICLE 10 OR LIMIT EITHER PARTY’S LIABILITY FOR (A) A BREACH OF ARTICLE 9 (CONFIDENTIALITY) OR (B) FOR SUCH PARTY’S (OR ITS AFFILIATE’S) GROSS NEGLIGENCE, FRAUD OR WILLFUL MISCONDUCT. 12.11 Complete Agreement; Amendments. This Agreement, together with the Schedules and Exhibits hereto, constitute the entire agreement between the Parties regarding the subject matter hereof, and all prior representations, understandings and agreements regarding the subject matter hereof, either written or oral, expressed or implied, are superseded and shall be and of no effect. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. No provision of this Agreement may be amended or modified other than by a written document signed by authorized representatives of each Party. 12.12 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed to be an original and together shall be deemed to be one and the same agreement. 12.13 Interpretation.

Unless specified to the contrary, references to Sections, Schedules or Exhibit mean the particular Sections, Schedules or Exhibit to this Agreement and references to this Agreement include all Exhibit hereto. In the event of any conflict between the main body of this Agreement and any Exhibit hereto, the main body of this Agreement shall prevail. Unless context
