*****Confidential Material redacted and filed separately with the Commission.

ARTICLE 1. DEFINITIONS

As used in this Agreement, the following terms, whether used in the singular or the plural, shall have the following meanings:

1.1 "Affiliate" means any corporation or non-corporate business entity, which controls, is controlled by, or is under common control with a party to this Agreement. A corporation or non-corporate business entity shall be regarded as in control of another corporation if it owns or directly or indirectly controls at least fifty-one percent (51%) of the voting stock of the other corporation, or (i) in the absence of the ownership of at least fifty-one percent (51%) of the voting stock of a corporation, or (ii) in the case of a non-corporate business entity, if it possesses, directly or indirectly, the power to direct or cause the direction of the management and policies of the corporation or non-corporate business entity, as applicable. Notwithstanding the foregoing, the Government of Japan and other entities controlled by the Government of Japan (other than through Japan Tobacco Inc.) are not considered Affiliates of Sublicensee.

1.2 “Combination Product” means a Product containing one or more therapeutically active ingredients in addition to the Compound.

1.3 "Compound" means ferric citrate: FeC₆H₅O₇• xH₂O

1.4 *****

1.5 “Field” means the field of nephrology.

1.6 “Follow-on Product” means products, other than the Product, which contain ferric ion as an active pharmaceutical ingredient for use in the Field, either alone, or in combination with one or more therapeutically active ingredients.

1.7 “Improvements” means any and all improvements, materials, technical data and information whether patented or unpatented, including but not limited to any changes to, or new therapeutic applications for, the Compound, the Product or in the Sublicensor Know-How or Sublicensee Know-How including, but not limited to any analogues, or derivatives of the Compound, and changes in the manufacturing process for the Compound

or the Product which are conceived or reduced to practice during the term of this Agreement.

1.8 "Indication" means any therapeutic application for a Product (i) for the treatment of hyperphosphatemia in end-stage renal disease, and (ii) for all other indications covered by the Patent Rights.

1.9 “Initiation” means the administration of the first dose to the first patient in a clinical trial.

1.10 "Net Sales" with respect to any Product means the gross sales (i.e. gross invoice prices) of such Product billed by Sublicensee and its sublicensees, if any, to Third Party customers on all sales of a Product, and exclusive of inter-company transfer or sales, less the reasonable and customary deductions from such gross sales, including:

(a) actual credited allowances to such Third Party customers for spoiled, damaged, outdated and returned Product and for retroactive price reductions,

(b) the amounts of trade, cash discounts and rebates, to the extent such discounts and rebates were not deducted by Sublicensee at the time of invoice in order to arrive at the gross invoice prices,

(c) all transportation, handling charges and freight insurance, sales taxes, excise taxes, use taxes or import/export duties paid, and

(d) all other reasonable and customary allowances and adjustments actually credited to customers whether during the specific royalty period or not.

In the event that the Product(s) is sold as part of a Combination Product, the Net Sales of the Product(s), for the purposes of determining royalty payments, shall be determined by multiplying the Net Sales of Combination Product (as defined in the standard Net Sales definition) by the fraction, A / (A+B) where A is the weighted average sale price of the Product(s) when sold separately in finished form (as defined below), and B is the weighted average sale price of the other product(s) sold in the Sublicense Territory separately in finished form.

In the event that the weighted average sale price of the Product(s) can be determined but the weighted average sale price of the other product(s) in the Sublicense Territory cannot be determined, Net Sales for purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product by the fraction A / C where A is the weighted average sale price of the Product(s) when sold separately in finished form and C is the weighted average selling price of the Combination Product.

In the event that the weighted average sale price of the other product(s) in the Sublicense Territory can be determined but the weighted average sale price of the Product cannot be determined, Net Sales for purposes of determining royalty payments shall be calculated by multiplying the Net Sales of the Combination Product by the following formula: 1 - (B/C) where B is the weighted average sale price of the other product(s) when sold separately in finished form and C is the weighted average selling price of the Combination Product.

In the event that the weighted sale price of both the Product(s) and the other product(s) in the Combination Product in the Sublicense Territory cannot be determined, the Parties will attempt to agree on an appropriate weighted average sale price of both the Product(s) and the other product(s) in the Combination Product, and lacking such agreement the Net Sales of the Product(s) shall be deemed equal to fifty percent (50%) of the Net Sales of the Combination Product.

By way of example, the parties assume a Combination product “C” consisting of the Product “A” and the other product “B.” When the weighted average sale prices in the Sublicense Territory of A, B and C are 50, 40 and 90, respectively, the parties agree that the fraction to be used for Net Sales calculation for determining royalty payments shall become as follows:

i)	in case the “50” and ”40” are known, 50/(50+40), i.e., 5/9;

ii)	in case the “40” is unknown but “90” is known, 50/90, i.e., 5/9;

iii)	in case the “50” is unknown but “90” is known, 1-40/90, i.e., 5/9; and

iv)	in case none of those is known, 1/2 unless otherwise agreed between the parties.

The weighted average sale price for a Product, other product(s), or Combination Product shall be calculated once each calendar year and such price shall be used during all applicable royalty reporting periods for the entire calendar year. When determining the weighted average sale price of a Product, other product(s), or Combination Product, the weighted average sale price shall be calculated by dividing the sales dollars (translated into U.S. Dollars) by the daily dose units of active ingredient sold during the twelve (12) months (or the number of months sold in a partial calendar year) for the respective Product(s), other product(s), or Combination Product. In the initial calendar year, a forecasted weighted average sale price will be used for Product(s), other product(s), or Combination Product. Any over or under payment due to a difference between forecasted and actual weighted average sale prices will be paid or credited in the first royalty payment of the following calendar year.

The Parties acknowledge that the foregoing determination for Net Sales of Combination Products may not be the same as the determination for Net Sales of Combination Products to be agreed upon between Sublicensor and Panion in accordance with the Panion License Agreement. Sublicensor agrees to use its commercially reasonable efforts to obtain Panion’s agreement to adopt the terms of this Section 1.10 to calculate Net Sales of Combination Products and will keep Sublicensee informed of ongoing negotiations concerning the provisions for Combination Products with Panion. In the event Sublicensor and Panion agree upon a different determination, Sublicensor shall immediately seek Sublicensee’s consent to amend this Section 1.10 to match such determination, which consent shall not be unreasonably withheld or delayed.

The sale of a Product solely for the research or clinical testing of such Product shall be excluded from the computation of Net Sales of such Product, provided that Sublicensee's sale of the Product was at cost, and such Product was used for research or clinical testing.

1.11 "Patent Rights" means the patents and patent applications set forth in Exhibit 1 (which shall be updated from time to time by Sublicensor), patents and patent applications in which Sublicensor holds rights and which are directed to Sublicensor’s interest in Improvements, and any and all patents in which Sublicensor holds rights and that may issue from all such patent applications, including any and all divisions, continuations, continuations-in-part, extensions, substitutions, renewals, registrations, supplementary protection certificates, revalidations, reissues or additions of or to any of the aforesaid patents and patent applications, and any additional patents or patent applications to which Sublicensor acquires rights, including rights to license, during the term of this Agreement which pertain in any way to the use or manufacture of the Compound or the Product.

1.14 "Registration" in relation to any Product means such approvals by a Regulatory Authority in a country or community or association of countries as may be legally required before such Product may be commercialized in such country or community or association of countries.

1.15 “Regulatory Authority” means the Ministry of Health, Labor and Welfare of Japan (hereinafter referred to as the “MHLW”) and any other applicable regulatory authority in the Sublicense Territory involved in granting regulatory approval for the Product.

1.16 “Sublicense Territory” means Japan.

1.17 “Sublicensee Development Data” means and includes all data relating to the Compound or the Product and all chemistry, manufacturing and control data relating to the development and manufacture of the Compound or the Product, results of pre-clinical and clinical studies and all other documentation containing or embodying any pre-clinical, clinical, chemistry, manufacturing and control data relating to any application for Registrations for a Product, including, but not limited to, documents submitted to the Regulatory Authority, which is generated or acquired by Sublicensee during the term of this Agreement.

3.2 Sublicensing. Sublicensee shall be entitled to sublicense to third parties the right to manufacture the Product or the Compound, provided such third party manufacturers are permitted to sell only to Sublicensee or their Affiliates. Except as expressly permitted under Sections 3.1 and 3.2, Sublicensee may not grant further sublicenses under this Agreement without the written consent of Sublicensor, which consent shall not be unreasonably withheld or delayed. For the avoidance of doubt, Sublicensor and Sublicensee agree that this Section does not apply to Third Party distributors and that Sublicensee may contract with Third Party distributors without the written consent of Sublicensor.

3.3 Retained Rights. The grant of licenses under Section 3.1 shall not preclude Sublicensor from utilizing the Patent Rights and Sublicensor Know-How, and any Improvements related thereto, for the purpose of carrying out development and commercialization activities relating to the Product in connection with Sublicensor’s rights outside of the Sublicense Territory, provided, however, that Sublicensor shall not sell and shall cause its Affiliates and its sublicensees not to sell Compound or Product to customers outside the Sublicense Territory which Sublicensor, its Affiliate or its sublicensee knows, or has reason to know, plan to resell for use in the Sublicense Territory. In addition, Sublicensor will not conduct clinical trials of the Compound or Product in the Sublicense Territory except upon the prior written consent of Sublicensee.

3.4 Sublicense Territory. Other than as permitted by this Article 3, Sublicensee shall not develop, manufacture, sell, use, offer for sale or import any Product or Compound outside of the Sublicense Territory, without the prior written consent of Sublicensor, which Sublicensor may grant or withhold in its sole discretion. Sublicensee shall not sell and shall cause its Affiliates and its sublicensees not to sell Compound or Product to customers in the Sublicense Territory which Sublicensee, its Affiliate or its sublicensee knows, or has reason to know, plan to resell for use outside the Sublicense Territory.

3.5 Territories without Patent Protection. Nothing in this Agreement precludes Sublicensee from developing, manufacturing, selling, using, offering for sale or importing Product in territories where Patent Rights do not exist or have already expired in their entirety. Notwithstanding the foregoing, Sublicensee shall not be entitled to use Proprietary Information solely owned by Sublicensor outside of the Sublicense Territory other than to make, manufacture, have made or have manufactured the Product outside the Sublicense Territory for sale within the Sublicense Territory.

3.6 Joint Steering Committee. To coordinate the activities under this Agreement, the parties will form a Joint Steering Committee (the “JSC”). The JSC will meet on a schedule to be determined by parties, but not less than twice yearly, and will be responsible for generally sharing information regarding the activities of the parties and shall include, without limitation, (a) review of non-clinical and toxicology programs to maximize the potential for use in multiple territories, (b) periodic updates on the status of the clinical development program and sharing of pharmacovigilance information, (c) review of marketing plans and sales forecasts and the coordination of activities at international conferences, (d) coordination of marketing activities that have an international component, including medical education and promotion, and (e) determining cost allocation for joint activities.

Sublicensor and Sublicensee shall each appoint one of its members as a JSC co-chair (“JSC Co-Chair”). Sublicensor’s JSC Co-Chair shall be chairperson of all the JSC meetings. The JSC Co-Chairs shall be jointly responsible for preparing the meeting agenda, and Sublicensor’s JSC Co-Chair shall be responsible for preparing the first draft of the minutes from such meeting. JSC meeting minutes shall be distributed in draft form to the members of the JSC not later than thirty (30) days following each JSC meeting, and shall be deemed accepted and effective unless the other Party’s JSC Co-Chair has objected to the same in writing within thirty (30) days of its receipt of such minutes. Final minutes of each JSC meeting shall be promptly distributed to the Parties. Each Party shall bear its own personnel and travel costs and expenses relating to JSC meetings.

3.7 Joint Development Team. The parties will form a Joint Development Team (the “JDT”). The JDT will meet on a schedule to be determined by the parties but not less than twice yearly and will be responsible for facilitating the exchange of preclinical data, clinical data, information, materials and results between Sublicensor and Sublicensee and for consulting on the regulatory development of Product in the Sublicense Territory, including regulatory filings relating to manufacture of Product for the Sublicense Territory and consultation as to changes in specifications or other changes for Product in the Sublicense Territory.

3.8 Alliance Managers. Each Party shall designate one (1) alliance manager (the “Alliance Manager”). One of the JSC Co-Chairs or JDT Co-Chairs may also serve as the Alliance Manager of the Party. The Alliance Managers will manage and oversee operational activities in connection with this Agreement, and will serve as the contact persons concerning on-going operations under this Agreement. The Alliance Managers shall promote effective communication between the Parties and coordination of the Parties’ activities and responsibilities in furtherance of the development and commercialization of Product in the Field in the Sublicense Territory.

3.9 Committee Decision and Dispute Resolution. Sublicensee shall be solely responsible for making final decisions arising out of the JSC, JDT or such other committee(s) as may be established (“Other Committee(s)”). Notwithstanding the foregoing, in the event that Sublicensor has a commercially reasonable belief that action to be taken by Sublicensee is reasonably likely to have a material adverse impact on its activities, or the activities of its sublicensees, outside the Sublicense Territory, Sublicensor shall notify Sublicensee of such belief. In case Sublicensee disagrees with such belief by Sublicensor, and the JSC, JDT or Other Committee fails to reach unanimous agreement on such a matter and that disagreement cannot be resolved within a period of fifteen (15) business days following the meeting of the JSC, JDT or Other Committee, the matter shall be referred to the Chief Executive Officer of Keryx and to the President of the JT Pharmaceutical Division for discussion and, if not resolved in such manner, shall be subject to Arbitration pursuant to Article 19.

In addition, Sublicensee will pay to Sublicensor additional non-refundable, non-creditable license fees as follows:

(a) Within ten (10) business days following receipt by Sublicensee of *****.

(b) Within ten (10) business days following receipt by Sublicensee of *****.

*****.

4.2 Milestone Payments. Sublicensee will pay to Sublicensor non-refundable, one-time milestone payments as follows:

*****Confidential Material redacted and filed separately with the Commission.

4.3 Sales Milestone Payments. Sublicensee will pay to Sublicensor the following non-refundable, one-time milestone payments as follows:

(a) Within sixty (60) days following attainment of annual Net Sales in Japan equal to *****.

(b) Within sixty (60) days following attainment of annual Net Sales in Japan equal to *****.

For purposes of this Section 4.3, annual Net Sales shall be calculated on a calendar year basis. Nothing herein shall preclude multiple milestone payments from being paid in a given 12-month period if multiple milestones have been reached.

4.4 Limitations. It is understood and agreed that Sublicensee shall pay the milestone payments set forth in Sections 4.2 and 4.3 only with respect to the first Indication for which a Product achieves a particular milestone event, and regardless of the number of Products which achieve a particular milestone event and regardless of the number of times which a particular milestone event is achieved.

4.5 Payment Method. All payments of license fees and milestones under this Article 4 shall be made by wire transfer in the United States currency to a designated bank account of Sublicensor.

ARTICLE 5. ROYALTIES

5.1 Royalties. In consideration of the sublicense rights granted to Sublicensee hereunder, for each Product where the manufacture, use or sale of such Product would but for the license granted hereunder, infringe a Valid Claim, Sublicensee shall pay to Sublicensor a royalty on their respective Net Sales, as follows:

*****Confidential Material redacted and filed separately with the Commission.

(a) a royalty of ***** of annual Net Sales equal to or less than *****;

(b) a royalty of ***** of annual Net Sales between *****;

For purposes of this Section 5.1, royalties shall be calculated based on total Net Sales in any given calendar year. By way of example, if in a given calendar year Net Sales were forty (40) billion Japanese Yen, then the amount of royalty owed for that year would be ***** Japanese Yen (calculated as the sum of ***** x ***** plus ***** x ***** plus ***** x *****). Notwithstanding the foregoing, in the event (i) the Panion License Agreement expires before the termination or expiration of this Agreement and Sublicensor is no longer required to pay royalties to Panion under the Panion License Agreement, the applicable royalty percentage to be paid by Sublicensee to Sublicensor under clauses (a), (b) and (c) of this Section 5.1 shall be reduced to *****, ***** and *****, respectively, or (ii) subject to Section 16.3, the Panion License Agreement is terminated before the termination or expiration of this Agreement, the royalties and other amounts to be paid by Sublicensee to Sublicensor shall be reduced by all royalties and other amounts payable directly by Sublicensee to Panion.

5.2 Accrual of Royalties. No royalty shall be payable on a Product made, sold, or used for research or clinical testing purposes or distributed as samples, provided such samples are sold by Sublicensee at cost. No multiple royalty shall be payable because the manufacture, use, or sale of a Product is covered by more than one Valid Claim.

5.3 Royalty Withheld due to Invalid Claims. In the event that all applicable claims of a patent included within the Patent Rights under which Sublicensee is paying a royalty according to Section 5.1 shall be held invalid or unenforceable by a court of competent jurisdiction in the Sublicense Territory, Sublicensee may withhold payments of royalties which would otherwise have been due on Net Sales in the Sublicense Territory by reason of Sections 4.3 and 5.1 until such judgment shall be finally reviewed by an unappealed or unappealable decree of a higher court of competent jurisdiction in the Sublicense Territory. The Sublicensee shall promptly repay Sublicensor any withheld

royalty payments upon a final adjudication that the applicable claims of a patent included within the Patent Rights under which Sublicensee is paying a royalty under Section 5.1 are valid and enforceable. For clarification, the aforementioned withheld royalty shall not bear any interest thereon.

*****Confidential Material redacted and filed separately with the Commission.

5.4 Compulsory Licenses. If Sublicensee is caused to grant a compulsory license to any Third Party with respect to a Product in the Sublicense Territory, then the royalty rate to be paid by Sublicensee on Net Sales due on such Product in that country under Section 5.1 shall be reduced to the rate paid by such Third Party compulsory Sublicensee on such Product.

5.5 Third Party Royalties. Sublicensor shall be responsible for payment of third party royalties owed on sales of Product in the Sublicense Territory with respect to any issued patent or patent application that has been published by the applicable patent office anywhere in the world prior to and including the date that is two (2) years after the Effective Date that are required to secure Freedom to Operate in the Sublicense Territory. For the purposes of this Agreement, “Freedom to Operate” shall mean such valid patents that, but for a license, would be infringed by the development, manufacture, use or sale of a Product for the Indication. With respect to patents or patent applications that are published by the applicable patent office anywhere in the world more than two (2) years after the Effective Date that are required to secure Freedom to Operate in the Sublicense Territory, then (a) if a license to such patent is limited to the Sublicense Territory, then Sublicensor and Sublicensee shall each be responsible for ***** of such license fees and royalty obligations; and (b) if a license to such patent includes countries outside the Sublicense Territory, then Sublicensor shall be responsible for ***** of such license fees and royalty obligations and Sublicensee shall be responsible for ***** of such license fees and royalty obligations. Notwithstanding the foregoing, Sublicensor’s obligation to pay Third Party royalties, including, without limitation, royalties owed to Panion, shall not exceed the sales milestone payments and royalties to which Sublicensor is entitled under Sections 4.3 and 5.1 of this Agreement.

5.6 Withholding Tax.

Specifications for Development Supplies to be delivered pursuant to this Section 10.1 and (if applicable) the Quality Agreement(s) shall be those approved and utilized by Sublicensor and presented to the JDT. To the extent that Sublicensee desires to obtain Development Supplies that are manufactured in accordance with different specifications, Sublicensee may chose to be solely responsible for securing such Development Supplies (from Sublicensor’s Third Party Manufacturer or otherwise). Development Supplies shall be provided to Sublicensee along with a COC, relevant batch records and a COA for each shipment.

The parties shall duly review and discuss all specifications and CMC controls to define the Japanese regulatory requirements for Development Supplies with the goal of ensuring that they are fully-compliant with such requirements for each stage of Pharmaceutical Development ("CMC Requirements"). Once the Parties have agreed on such CMC Requirements, which agreement shall not be unreasonably withheld or delayed, Sublicensor will make reasonable efforts, to the extent possible within existing technical and commercial constraints, to ensure Development Supplies prepared for Sublicensee meet such CMC Requirements. In no event will Sublicensor deliberately prepare Development Supplies which do not meet such requirements or ship such to Sublicensee without Sublicensee's express written consent. In the event Development Supplies prepared for Sublicensee do not meet the CMC Requirements, Sublicensor will notify Sublicensee within two business days of such knowledge and the Parties will jointly review and discuss the appropriate course of action. As soon as practical after the Effective Date, the Parties shall establish a joint Quality Agreement for Development supplies which Agreement shall be included herein by reference.

At any time during clinical development in the Sublicensee Territory, Sublicensee (or its designee) shall have the right to audit facilities that manufacture any of the Development Supplies as well as storage or testing facilities for them. Sublicensor shall cooperate and cause each Third Party Manufacturer and/or testing facility to cooperate with Sublicensee (or its designee) for such audit.

10.1.8 Audit of facilities by Regulatory Authority. If Regulatory Authority requests an inspection or audit of Sublicensor’s or its Third Party Manufacturer's facility and Sublicensee with regard to the intermediates, Compound or Product (including a manufacturing, storage or testing facility for each) anywhere in the world, Sublicensor shall use good faith efforts to cooperate with Sublicensee and Regulatory Authority in fulfilling such request (and, if applicable, shall use good faith efforts to cause its Third Party Manufacturer to cooperate with Regulatory Authority and Sublicensee in fulfilling such requested inspection or audit). Following receipt of the inspection or audit observations of the Regulatory Authority (a copy of which Sublicensor shall promptly provide to Sublicensee), Sublicensor shall use good faith and reasonable efforts to consult with Sublicensee and prepare the response to any such observations, in English.

10.2 Transfer of Manufacturing Technology. The Parties jointly acknowledge that the activities which are the subject of this Section 10.2 are complex, time-consuming, and require good communication to execute successfully in a timely manner. Accordingly, at the time Sublicensee invokes any of these parts, the parties shall form a Manufacturing Steering Team to plan and execute the activities. The reasonable commercial efforts of Sublicensor cannot make up for lack of adequate planning, task definition, and advance notice. It is agreed that the Manufacturing Steering Team meetings shall be held quarterly and its activities shall be governed by Section 3.6.

10.2.1 Transfer by Sublicensor. At any time during the Term of the Agreement, upon reasonable request by Sublicensee (through the Alliance Managers), Sublicensor shall provide to Sublicensee copies of written documentation pertaining to manufacturing technologies, but only to the extent that such documentation is necessary for Sublicensee (i) to conduct its pre-clinical and clinical development activities or (ii) to make arrangements for supply of Compound, formulated Compound (interim product) (if any) and/or Product for Sublicensee’s use in Phase III clinical trials, and commercialization of Product in the Field in the Sublicensee Territory.

Sublicensor and Sublicensee acknowledge that, pursuant to the Japanese Pharmaceutical Affairs Law, certain quality agreements are required to be entered into among Sublicensee and each direct or indirect supplier of intermediates, Compound, formulated Compound (interim product) (if any) and Product (each such agreement, a “Third Party Quality Agreement”), and that such Third Party Quality Agreement is required to enable Sublicensee to directly control quality matters with respect to intermediates, Compound, formulated Compound (interim product) (if any) and Product. The Parties also acknowledge that each such Third Party Quality Agreement shall be filed with Regulatory Authority at the time of the filing of the market approval for finished Product in the Sublicensee Territory. For this purpose, upon request of Sublicensee, Sublicensor shall use good faith efforts to reasonably cooperate with Sublicensee, and to cause each Third Party Manufacturer or supplier to cooperate with Sublicensee, in Sublicensee’s efforts to enter into such Third Party Quality Agreements with such Third Party(ies) in a timely manner.

10.2.3 Direct Supply Agreement with Third Party Manufacturers. At any time during the period when Sublicensor or its Affiliates is providing Development Supplies to Sublicensee, and until Sublicensee has a direct supply contract with Third Party contractors, upon reasonable request by Sublicensee, Sublicensor agrees to use good faith and reasonable efforts to (i) facilitate Sublicensee’s efforts to enter into supply agreements with Sublicensor’s or its Affiliates’ Third Party Manufacturers or other Third Party suppliers of intermediates, Compound, formulated Compound (interim product) (if any) or Product or starting materials, intermediates, or reagents for Development or commercial supply purposes (“Direct Supply Agreements”); and (ii) in connection with such Direct Supply Agreements, cooperate with Sublicensee to provide Sublicensee with reasonable access to pertinent manufacture technologies that are necessary for manufacturing intermediates, Compound, formulated Compound (interim product) (if any) and/or Product, including the information specified in clauses (a) through (g) of Section 10.1.4.

In order to obtain such accreditation, Sublicensor shall use good faith efforts to cooperate reasonably with Sublicensee in causing each Third Party Manufacturer to apply to Regulatory Authority by themselves or having Sublicensee apply on their behalf at least six (6) months prior to Sublicensee’s anticipated date for the filing of a marketing approval in Japan.

10.3 Sublicensor shall, in the event it wishes to be supplied with the Compound and/or the Product from Sublicensee and/or its Third Party Manufactures, enter into discussion with Sublicensee thereon. In case Sublicensee agrees to supply to Sublicensor said Compound and/or Product, then the Sections 10.1 and 10.2 hereinabove shall apply mutatis mutandis.
