As of the Effective Date it is estimated that the Facility Construction Cost will be approximately [***]) (“Estimated Facility Cost”), which may be revised in a duly-executed amendment to this Agreement pursuant to Section 11.l. hereof. BioVectra will confirm the Estimated Facility Cost upon completion and mutual approval of the Conceptual Design pursuant to Section 2.b. During the course of construction, BioVectra will notify Keryx in writing of potential cost variances which may increase or decrease the Facility Construction Cost by [***] of the Estimated Facility Cost within [***] days of its awareness of the foregoing and will work together in good faith to resolve, to the extent possible, the cost increases. Any cost savings will bring the Facility Construction Cost below the Estimated Facility Cost, thereby decreasing the Facility Reimbursement Payment accordingly. The Parties will share equally all cost increases that bring the Facility Construction Cost more than [***] over the Estimated Facility Cost; however, BioVectra will not be responsible to share in cost increases which result from the decision by Keryx to deviate from the approved Conceptual Design. Any true-ups will happen in accordance with Section 2.o. below.

Within [***] of Substantial Completion, the Parties will engage a mutually-agreed independent regulatory expert (a “Regulatory Expert”) of recognized standing in the industry to perform a mock FDA audit of the Facility. If the audit of the Facility determines that due to BioVectra’s failures, the Facility is not prepared for

With respect to all Equipment, BioVectra shall provide engineering project management and process validation, qualification support, installation and commissioning services. BioVectra shall manage the installation, commissioning and validation activities of such Equipment.

BioVectra shall disclose to Keryx in writing within a reasonable time after Keryx’s written request: (i) all persons and entities proposed by BioVectra to produce, construct, fabricate or supply any component part of the Facility, including all Equipment; (ii) the location(s) where each component of the Facility, including all Equipment, will be produced, constructed or fabricated or from which such component shall be sourced; and (iii) any other information relating to sourcing and/or construction and assembly of the Facility which is reasonably requested by Keryx. BioVectra shall promptly pay to each Vendor the amount due for such Vendor's work, provided BioVectra shall have the right to withhold payment to any of its Vendors who have furnished defective, substandard, and/or incorrect materials, workmanship, or deliverables. Keryx shall have no obligation to pay, or cause the payment of, any money to any Vendor or any other party acting through, under or on behalf of BioVectra.

BioVectra shall build, construct and assemble the Facility in strict accordance with the Design Documents, as may be updated, amended, or modified and otherwise in accordance this Agreement and all Applicable Law. Any material update, amendment or modification being either approved in writing by the Supply Committee within a reasonable time from receipt, not to exceed [***] days, or escalated for approval pursuant to Section 2.e.

Not in limitation of any other provision of this Agreement, Keryx shall have the right of access to any of BioVectra’s and/or its Vendor’s plants (including the Facility) as may be necessary to allow Keryx to: (i) review BioVectra’s progress; (ii) verify that the Facility is being built, constructed and assembled so as to conform to the Design Documents, the Timeline, and this Agreement; and/or (iii) verify that a progress payment contingency has been completed. Payments to BioVectra under this Agreement shall not constitute acceptance or impede Keryx’s right to subsequently inspect the Facility or pursue remedies available to it.

The Parties shall provide their commercially reasonable efforts to minimize the costs of procurement, installation and commissioning of the Equipment. BioVectra shall provide Keryx with quotes and copies of all applicable invoices from Vendors, for the costs of procurement, transportation, installation, and commissioning of the Equipment.

Over the course of the construction of the Facility Keryx will make payments to BioVectra within [***] days of receipt of an undisputed invoice at ***@***. BioVectra will issue such invoices upon reaching the following milestones:

Five million US dollars ($5,000,000 USD) on [***] by December 31, 2017;

[***]

[***].

BioVectra will notify Keryx in writing of the Facility Construction Cost actually incurred by BioVectra and any details of the Facility Construction Cost reasonably requested by Keryx within [***] days following Substantial Completion of the Facility. While Keryx shall have no liability or obligation to finance the Facility Construction Cost, which shall be for the sole account of BioVectra, the Parties anticipate that BioVectra will recoup those costs through the combination of the premiums paid by Keryx on purchase of volumes of product under the [***], the milestone payments set out in Section 2.l; and the Facility Reimbursement Payment due under this Agreement. Any cost savings will bring the Facility Construction Cost below the Estimated Facility Cost, thereby decreasing the Facility Reimbursement Payment accordingly. The Parties will share equally all cost increases that bring the Facility Construction Cost more than [***] over the Estimated Facility Cost; however, BioVectra will not be responsible to share in cost increases which result from the decision by Keryx to deviate from the approved Conceptual Design.

The Facility Reimbursement Payment will be reconciled by the Parties (for example due to a variance in the Facility Construction Cost from the Estimated Facility Cost, not achieving milestones or variance in purchases of product under the [***]), prior to commencement of Supply Term through an increase or decrease in the Facility Reimbursement Fee, an extension of the Pay Back Period, or alternate arrangement mutually agreed to in writing by both Parties. This Agreement will be amended to reflect any modification to the Facility Reimbursement Payment (and consequently

Keryx will pay the Facility Reimbursement Payment over volumes of Product purchased over the [***] of the Supply Term (“Pay Back Period”). The Facility Reimbursement Payment will be prorated over [***] MT of Product forecasted by Keryx to be purchased during the Pay Back Period, prorated annually. The price of Product is set out in Appendix 1 which, for the Pay Back Period, has an associated Facility Reimbursement Fee. BioVectra will true-up, within [***] of months [***] (estimated to be [***]), [***] (estimated to be [***]) and [***] of the Pay Back Period (estimated to be [***]), for any underpayment or overpayment by Keryx due to the forecasted quantity of Product being more or less than quantities of Product actually purchased or for any overpayment by Keryx due to, for example: (i) the forecasted quantity of Product, or product, being less than quantities of Product, or product, actually purchased under this Agreement or the [***], respectively, or (ii) cost savings realized against the Estimated Facility Cost. BioVectra shall perform such true-up by sending to Keryx at ***@*** an associated invoice (for underpayments) or credit (for overpayments).

To secure the expanded working capacity of the Facility, Keryx will notify BioVectra in writing of its intention to move forward with the expansion of the Facility to [***] working capacity within [***], or some other time frame as agreed in writing between the Parties. Once written notification from Keryx is received by BioVectra, the Parties will enter into negotiation on terms for capital investment and, as appropriate, extension of this Agreement. If such notification is not made within the agreed time frame, or Parties are not able to agree on terms for expansion within [***] of Keryx’s notification to BioVectra, BioVectra will have the right to use the expanded working capacity thereafter, as long as any use of the expanded working capacity does not interfere with Keryx’s quality and regulatory requirements for Product.

Keryx will have, upon reasonable notice to BioVectra, the right to monitor, review and inspect the construction site for the Facility and the Facility under construction, including without limitation all equipment therein, any time during that construction and on and after the Substantial Completion of the Facility. BioVectra shall give due consideration to any comments provided by Keryx resulting from the monitoring, review and inspection of the construction site, Facility and equipment.

After Substantial Completion, Parties will commence validation of the process as per the approved protocol. Product resulting from validation runs will be priced according to Appendix 1. BioVectra will deliver and the Parties will both sign a process validation report to mark the successful completion of validation and Facility readiness for commercial supply. Validation is based on the manufacturing procedure for product purchased under the Manufacture and Supply Agreement and the Specifications attached hereto in Appendix 2, unless otherwise agreed in writing by the Parties. Any changes to the Manufacturing Procedure or Specifications, will

Within [***] days after the Effective Date, Keryx and BioVectra shall establish a supply committee to facilitate regular and efficient communication between the Parties regarding their activities and issues relating to the design and construction of the Facility and the manufacture and supply of Product under this Agreement (“Supply Committee”). Keryx and BioVectra each shall designate [***] representatives with appropriate expertise to serve as members of the Supply Committee, which membership may change during the course of the various activities under this Agreement (i.e. during the design and construction phases of the Facility vs. the Product manufacture and supply activities thereafter). Each Party shall select [***] person appointed by it to the Supply Committee to serve as co-chair. Either Party may designate substitutes for its Supply Committee representatives to participate if one or more of such Party’s designated representatives are unable to be present at a meeting. A Party may replace its representatives serving on the Supply Committee from time to time by written notice to the other Party specifying the prior representative(s) to be replaced and the replacement(s) therefor. The co-chairpersons of the Supply Committee shall be responsible for calling meetings, preparing and circulating an agenda in advance of each meeting. One of BioVectra’s Supply Committee representatives shall be responsible for preparing and issuing minutes of each meeting within [***] thereafter. Such minutes shall not be finalized until Keryx reviews and confirms with BioVectra the accuracy of such minutes in writing within [***] [***] after Keryx receives such minutes. If BioVectra does not receive any written comments on such minutes from Keryx within such [***] period, then such minutes shall be deemed to be approved by Keryx.

The Supply Committee shall meet at least [***] until successful completion and validation of the Facility and the Manufacturing Procedure and thereafter once every [***], and more frequently as the Parties deem appropriate, on such dates, and at such places and times as the Parties shall agree. Both Parties may agree in writing to cancel one or more Supply Committee meetings. Meetings of the Supply Committee may be held by audio or video teleconference with the consent of each Party. Meetings of the Supply Committee that are held in person shall occur at such place as the Supply Committee may determine based on the agenda proposed for the meeting and the place of convenience as relating to the agenda items. The members of the Supply Committee also may be polled or consulted from time to time by means of electronic mail or correspondence, as deemed necessary or

The Supply Committee shall operate by consensus. With respect to matters to be discussed by the Supply Committee, the representatives of each Party shall present a unified position on behalf of such Party. In the absence of consensus of Supply Committee members with respect to any matter before the Supply Committee, such matter shall be deemed not to have been approved by the Supply Committee and the matter shall be escalated to each Party’s senior management for review and consideration.

In addition to its overall responsibility for overseeing the Parties’ activities with respect to design and construction of the Facility and manufacture and supply of Product under this Agreement, the Supply Committee shall in particular:

The Supply Committee shall have only those powers set forth herein, and, without limiting the generality of the foregoing, shall not have any power to amend, modify or waive compliance with this Agreement.

During the Term of this Agreement, BioVectra will manufacture Product, utilizing drying technology BioVectra considers proprietary (the “BV Drying Technology”), exclusively for Keryx for the US, Europe and any other market in which Keryx has license to sell (“Territory”). Without limiting Keryx’s purchase obligations below, nothing herein shall limit or prohibit Keryx from purchasing Product from any third party.

BioVectra will, at its sole cost and expense, purchase all materials used in the Manufacture of Product (“Materials”). Keryx understands and acknowledges that BioVectra will rely on Keryx’s purchase orders and forecasts in ordering the Materials required to meet the purchase orders. In addition, Keryx understands that to ensure an orderly supply of Materials, BioVectra may want to purchase Materials in sufficient volumes to meet the production requirements for Products during part or all of the forecast or to meet the production requirements of any longer period agreed to by BioVectra and Keryx. Accordingly, Keryx authorizes BioVectra to purchase Materials for the first [***] contemplated in the most recent forecast to satisfy the Product supply requirements hereunder. BioVectra may make other purchases of Materials for longer periods, if agreed to in writing by the Parties, to satisfy the Product supply requirements hereunder.

For the initial [***] months of the Supply Term, Keryx will submit a purchase order for a minimum of [***] of Product and for each [***] month period of the Supply Term thereafter (each a “Supply Period” and which are estimated to be [***] and, thereafter, calendar years [***]), Keryx to submit a purchase order for a minimum of [***] of Product (“Minimum Order Quantity”). If Keryx fails to submit a purchase order for the Minimum Order Quantity in any Supply Period, during the Supply Term, within [***] of the end of the Supply Period, BioVectra will perform a true-up and invoice Keryx for the difference between the Minimum Order Quantity and the actual quantity of Product purchased in that Supply Period multiplied by the price of Product. In the event that Keryx is unable to purchase the Minimum Order Quantity in any Supply Period due to BioVectra’s failure to perform its obligations under this Agreement, including BioVectra’s inability to manufacture Product on a commercial scale, supply Product from the Facility at the Working Capacity level or achieve timely delivery of Product, or due to force majeure, no amounts will be due to BioVectra hereunder regarding any such shortfall.

The price of Product is set out in Appendix 1 and, for the Pay Back Period, has an associated Facility Reimbursement Fee.

Keryx will provide BioVectra with a rolling [***] forecast (non-binding) of its annual volume requirements. Keryx will commence providing such rolling forecast at least [***] prior to Substantial Completion, following written notification from Supply Committee that such forecasting should commence, and update such forecast every

Purchase and shipment of Product will be in response to binding written purchase orders submitted by Keryx according to process set out herein. Keryx will place a binding purchase order for all its quarterly requirements of Product at least [***] prior to the commencement of the quarter (with Supply Committee providing Keryx prior written notice of commencement of the Supply Term pursuant to Section 1.ff.). Keryx will place such purchase orders hereunder, intending, to the extent practicable, for the Product quantity requirements not to substantially differ from quarter to quarter.

Purchase orders will be be confirmed by BioVectra for acceptance and delivery timing and BioVectra shall not reject any Keryx purchase orders for Product that fall within the [***] Working Capacity of this Agreement.

If, after the first [***] batches manufactured in the Facility, BioVectra delivers less than [***] of the volume of Product ordered by Keryx in any quarter (to a maximum of the quarterly Working Capacity), BioVectra shall issue a credit to Keryx in the amount of [***] of the price of the quantities of Product not delivered by BioVectra in the given quarter, at a price of [***]. Keryx will notify BioVectra of such failure to deliver and BioVectra will post the credit to Keryx’s account within [***] days of Keryx’s notification. If there is a dispute as to the quantity delivered, the Parties will work in good faith towards prompt resolution.

If, from [***] BioVectra delivers less than [***] of the volume of Product ordered by Keryx in a Supply Term (to a maximum of the current Working Capacity), BioVectra shall issue a credit to Keryx in the amount of [***] of the price of quantities of Product not delivered by BioVectra in the Supply Term at a price of [***]. Keryx will notify BioVectra of such failure to deliver and BioVectra will post the credit to Keryx’s account within [***] days of Keryx’s notification. If there is a dispute as to the quantity delivered, the Parties will work in good faith towards prompt resolution.

Keryx shall submit to BioVectra a purchase order for each delivery of a given Product, and BioVectra shall fulfill such purchase order in accordance with this Agreement. Each purchase order shall be on such form of purchase order or document as agreed between the Parties from time-to-time in writing and shall include (a) the quantities of Product and (b) shipping instructions and destination(s) (and for clarity, Keryx may designate a designee to receive shipments (e.g., a distributor)). BioVectra shall be obligated to manufacture and supply such quantities of Product as are set forth

Process Development.

Whether initiated by Keryx, BioVectra, or a joint effort of the two Parties, BioVectra may, at Keryx’s cost, from time to time and with the prior written agreement of Keryx, engage in Process Development Work. “Process Development Work” means the conduct by BioVectra of activities to develop, confirm and/or refine processes for producing the Product and/or activities to develop, optimize and/or scale-up a manufacturing process suitable for GMP Manufacture of the Product. A Party wanting to initiate Process Development Work will bring a proposed plan to the Supply Committee for consideration, approval, and further development. The Supply Committee will receive regular updates regarding the Process Development Work and generally oversee its progress. Any Improvements to the Manufacturing Procedure will be the sole and exclusive property of Keryx.

Following completion of any Process Development Work, BioVectra shall within the timeline approved by the Supply Committee provide Keryx with a final written report on the development work completed, including, if called for in the written project plan agreed by the Supply Committee for the Process Development Work, the impact of any such Process Development Work on the costs to Manufacture Product.

If called for in the written project plan agreed by the Supply Committee for the Process Development Work, BioVectra shall perform one or more process development runs and Manufacture non-GMP process development batches of Product in accordance with the project plan. BioVectra will provide the services to perform such process development runs and produce such process development batches in accordance with the project plan. BioVectra shall provide Keryx with all process development batches requested by Keryx that result from any partial or completed process development runs. While there will be no final specifications for acceptance of process development batches, the Parties will mutually agree on certain target quality attributes, to be set forth in the applicable project plan. BioVectra shall provide analytical testing of the batch as agreed by the Parties

If, as a result of any Process Development Work, the cost to Manufacture Product is reduced (including a situation in which the yield is increased or cycle time is reduced), the Parties agree to share, [***], the resulting reduction in cost, subject to Keryx consenting to, and the implementation by BioVectra of, the process development improvements resulting from the Process Development Work. Notwithstanding the foregoing, before any cost benefits are shared [***] between the Parties, Keryx will recoup the amounts paid to BioVectra to cover the Process Development Work costs via a mutually agreed Price reduction arrangement.

The Parties shall mutually agree on the proposed plan for Keryx’s reimbursement and the data supporting the proposed reduction in cost. If the Parties disagree, they shall submit such dispute to an independent pharmaceutical manufacturing expert agreed by the Parties (an “Expert”) for evaluation, provided that both Parties shall be entitled to observe and obtain copies of all results of such evaluation. The Expert must be of recognized standing in the industry, and consent to the appointment of such Expert will not be unreasonably withheld or delayed by either Party. The Expert will determine the resulting cost reduction. Both Parties shall cooperate with the Expert’s reasonable requests for assistance in connection with its evaluation hereunder. The findings of the Expert shall be binding on the Parties, absent fraud or manifest error. The Parties shall split evenly the cost of the Expert.

Non-Compete and Non-Use. Other than its pre-existing commitments to [***], during the Term and for [***] after expiry of Term (unless terminated by Keryx pursuant to Section 10.b.ii, 10.b.iii and for termination by BioVectra under Section 10.c.) BioVectra agrees that it will not, directly or with or on behalf of a third party, develop, market, advertise, promote, manufacture, supply, distribute, offer to sell or sell: (i) any Product (or any other product containing a bulk drug substance and/or final drug product which is the same as, or substantially similar to, the Product) or (ii) any products that are competitive with a Product for the control of serum phosphorus levels and/or iron deficiency in chronic kidney disease or that have the same mechanism of action (as reasonably determined by Keryx) for any other person or entity (other than for Keryx pursuant to this Agreement) without Keryx’s prior written consent. In all cases, under no circumstances will BioVectra (or any of its Affiliates) use any Keryx Technology, Improvements or Confidential Information of Keryx to manufacture, for itself or for any other person or entity other than for Keryx pursuant to this Agreement any product at any time, or for any other purpose other than for the manufacture of Product for Keryx hereunder, and such obligation

BioVectra will manufacture Product according to GMPs, Manufacturing Procedure, Specifications and quality requirements set forth in the Quality Agreement as well as in accordance with all Applicable Law (collectively, all the forgoing the “Manufacturing Requirements”). The Quality Agreement contains and governs all quality related matters and set forth the responsibility of the Parties with respect to certain tasks including change control, deviations, stability, complaints, records, sampling, testing, retaining of samples, release, as well as tasks related to regulatory reporting, investigations, and recalls. Each Batch of Product will be sampled and tested by BioVectra against the Specifications, and the quality assurance department of BioVectra will review the documentation relating to the manufacture of the Batch and will assess if the manufacture has taken place in compliance with the Manufacturing Requirements.

In addition to any release requirements set forth in the Quality Agreement, BioVectra will release Product, against agreed upon Specifications and provision to Keryx of a Certificate of Conformance, Certificate of Analysis, certificate of origin (including a BSE / TSE statement), and copies of Batch deviations (collectively “Batch Documentation”) for each Batch of Product will be delivered to Keryx by electronic mail in the form of a PDF. BioVectra will provide to Keryx following the release of each batch, a PDF scan of the executed Batch records. Upon request, and at Keryx’s cost, BioVectra will also deliver to Keryx all Records and Supporting Documentation in the possession or under the control of BioVectra relating to the manufacture of each Batch of Product (or any intermediate or component of Product). Any scope changes to the manufacturing schedule, release requirements or quality requirements and associated impact(s), including impacts to costs, will be reviewed and assessed prior to implementation, and in all cases subject to the prior mutual agreement of both Parties.

In addition to Section 5.a. above, as required by GMP, at release Product will be absent of any foreign particulate matter. Safety screening will be implemented by BioVectra as part of the Manufacturing Procedure to aid in the identification of foreign particulate matter. Absence of foreign particulate matter for the purposes of this Agreement shall be the absence of glass, metal, biological or polymeric material. Because Product contacts the glass, metal, and polymeric materials of the manufacturing surfaces as a condition of production, it is expected and understood that these surfaces can and will shed particles into Product at levels that are consistent with GMP (including 21CFR parts 210 & 211); equipment having been designed, fabricated and qualified to perform to pre-determined standards and materials of construction.

If particles larger than what would normally shed into Product are observed, Parties will investigate and evaluate risk of Product, and determine disposition. Any disputes between the Parties regarding whether Product conforms to GMP or the other requirements of the Agreement will be submitted to a neutral expert/laboratory for binding resolution pursuant to the procedures set forth below in Section 4.

During each [***] period, one lot of Product will be placed on [***] [***] stability program which shall provide data necessary to support the annual product quality review (APQR). Any additional lots for stability will be considered outside of the scope of this Agreement and a separate quotation will be provided for costs of any additional lots requested.

Facility Status. BioVectra shall, at its own cost and expense, ensure that at all times during the Term of this Agreement, the Facility is in a qualified and validated state appropriate for inclusion as a manufacturing site for Product as required by the applicable Authorities, Applicable Law, the Specifications and any Health Registrations and shall ensure that at all times there is sufficient capacity to manufacture Product ordered hereunder.

Location of Manufacturing Activities. Notwithstanding anything to the contrary contained herein, all manufacturing activities shall occur at the Facility and BioVectra may not change to a different facility (for all or any portion of the manufacture of Product hereunder) unless consented to by Keryx in writing (in its sole discretion); provided, that in all cases no change of Facility shall relieve BioVectra of any of its obligations under this Agreement. BioVectra shall provide to Keryx supporting data in order to permit Keryx to amend its (and its Affiliate’s and designee’s, as applicable) regulatory filings to reflect any such change and shall otherwise cooperate in good faith with Keryx to comply with all regulatory obligations arising out of such changes (and BioVectra shall reimburse Keryx for all costs incurred in connection therewith).

Quality Agreement. In the event of any discrepancy or inconsistency between the tasks listed in such Quality Agreement and the terms of this Agreement, the terms of the Quality Agreement will govern with respect to quality matters and other similar matters, and the terms of this Agreement shall govern with respect to all other matters; provided, that the Quality Agreement may not be interpreted or construed by either Party as amending or modifying in any way any terms of this Agreement except those terms specifically governed by the Quality Agreement. The Quality Agreement may be modified or amended by the Parties, in writing; provided, that such modification or amendment shall not be deemed to modify or amend the terms of this Agreement.

Batch Failure. BioVectra agrees to notify Keryx within [***] of discovery after any Batch failure which could result in BioVectra’s inability to meet the agreed upon delivery dates, or of learning of any failure of any Batch of Product to meet Specifications or the Manufacturing Requirements or if BioVectra has any other safety or efficacy concerns with respect to a Batch of Product. BioVectra agrees not to Reprocess or Rework any Batch of Product, or any intermediate in the manufacture of Product, without the prior written approval of Keryx in writing (in its sole discretion). Should Keryx provide such approval, BioVectra will Reprocess or Rework the affected Batch(es) or intermediate(s) in the manufacture of Product at its own cost. BioVectra will schedule any Reprocess or Rework as determined by BioVectra, according to its most efficient manufacturing schedule.

Sarbanes-Oxley Compliance. Without limiting the foregoing, if and to the extent reasonably necessary to ensure Keryx’s continuing compliance with the requirements of the Sarbanes-Oxley Act of 2002 (as determined by Keryx in its sole discretion), BioVectra shall, at Keryx’s request, provide the appropriate report(s) as established by the Statement on Standards for Attestation Engagements No. 16 (SSAE 16) (or its successor standard), and other report(s) as requested by Keryx covering the manufacturing services provided by BioVectra to Keryx. The audit will be performed at BioVectra’s expense and audit findings shall be provided to Keryx on an annual basis consistent with SSAE 16 (or its successor standard) and with the requirements of the Keryx. The report should be prepared by a public accounting firm that is reasonably acceptable to Keryx (preferably one of the Big Four – Deloitte, Ernst & Young, KPMG or PricewaterhouseCoopers). Any material weaknesses in BioVectra’s internal controls revealed by the audit will be promptly remedied by BioVectra.

Filing and Maintenance of the Health Registrations. As between the Parties, Keryx shall have the sole right to prepare and file for the Health Registrations, including the CMC, with the applicable Authorities, and, for clarity, BioVectra shall have no right to do so and shall not communicate with any Authorities in connection with any Health Registration. If determined by Keryx (in its sole discretion), Keryx shall have the right to include a designation of BioVectra and the Facility as a manufacturer and manufacturing site of Product in the applicable Health Registrations.

CMC Information. Keryx, in its discretion, may provide BioVectra with CMC information applicable to BioVectra for BioVectra to manufacture Product in accordance with this Agreement and the Health Registrations, and BioVectra shall comply with all such CMC information in performing its activities hereunder. Any changes to CMC section after the effective date of this Agreement, will need to be reviewed for scope changes to the manufacturing schedule, release requirements or quality requirements and associated impact(s), including impacts to costs prior to implementation. For clarity, all CMC information shall be considered Confidential Information of Keryx hereunder.

Regulatory Support for Maintaining Filings. For filings that occur after the Facility has been approved by the FDA, BioVectra shall perform, at Keryx’s cost at BioVectra’s FTE hourly rate, [***], (BioVectra’s FTE rate will be updated and posted to Keryx every [***]), the activities (including tests and also including at Keryx’s request, preparing documents to support CMC modules for filing or filing related support for the Health Registrations) in connection with the receipt and maintenance of the Health Registrations as requested in writing by Keryx from time to time, which activities shall be performed by BioVectra in compliance with all Applicable Law. In all cases, BioVectra shall be prepared for any and all inspections, including pre-approval inspections, by Authorities. Without limitation of the foregoing, BioVectra shall provide Keryx with such information and assistance as Keryx may reasonably request, at Keryx’s cost, for purposes of applying for and maintaining all relevant Health Registrations for Product including providing Keryx with all reports, authorizations, certificates, methodologies, specifications and other documentation in the possession or under the control of BioVectra (or any of its Affiliates) relating to the pharmaceutical/technical development and/or manufacture of Product or any component thereof. BioVectra hereby grants Keryx an irrevocable, perpetual, worldwide, fully paid-up license, with the right to grant sublicenses (through multiple tiers) to use such information, data and other BioVectra Technology reflected in such documentation for the purpose of obtaining and maintaining the Health Registrations for Product as well as a right of reference to any regulatory approvals of BioVectra for use in connection with Product.

Communications by Keryx. For purposes of clarity, nothing in this Agreement, including the provisions of this Section 5, shall restrict the right of Keryx (or its Affiliates or other designees) from taking an action that it deems to be appropriate or required by Applicable Law with respect to Product, including making a timely report to a given Authority with respect to Product.

BioVectra will invoice Keryx for Product upon Product [***] delivery by BioVectra. Keryx will pay for invoices less any holdback for disputed amounts, within [***] of invoice receipt. Transfer of ownership and, for the purposes of this Agreement

Keryx will be responsible for the shipping costs, customs, duties, clearances and fees for the shipment of Product from the Facility to Keryx's assigned destination. Keryx will also be responsible for the costs to insure Product while in storage at BioVectra if Keryx has requested that BioVectra store the Product rather than ship it after release. After Product delivery, Keryx will review the documentation received pursuant to Section 5.b. and, within [***] calendar days, either (i) provide a written authorization to ship, or (ii) reject Product in accordance with Section 6.d. Once BioVectra has received a written authorization to ship from Keryx, BioVectra shall promptly comply with Keryx’s shipping instructions. For the avoidance of doubt, BioVectra shall not ship Product from the Facility until either it has received Keryx’s written authorization to ship or more than [***] calendar days have passed since Product delivery. If so requested by Keryx, BioVectra shall store Product on site at the Facility for up to [***] days post delivery free of charge. Whether or not Product has shipped from the Facility, Keryx does not waive its right to reject the Product under Section 6.d. by not providing such rejection within the aforementioned [***] period.

Any services requested that are beyond the activities related to design and construction of the Facility, manufacture of Product or the ordinary support of the obligations of this Agreement, including changes to Products as specified for reasons other than to uphold compliance to the Quality Agreement, will be considered ad hoc services. BioVectra will charge Keryx according to at BioVectra’s FTE hourly rate, [***], (BioVectra’s FTE rate will be updated and posted to Keryx every [***]) for any such ad hoc services.

Keryx shall have [***] days from date of delivery to inspect Product for conformance to agreed upon Specifications and Manufacturing Requirements. Keryx will review the Batch Documentation for each Batch of Product and may test samples of the Batch of Product against the Specifications. During this review period, the Parties agree to respond promptly, but in any event within [***], to any reasonable inquiry or request for a correction or change by the other Party with respect to such Batch Documentation. Keryx has no obligation to accept a Batch if such Batch does not comply with the Manufacturing Requirements. If Keryx rejects a Batch of Product or a portion thereof pursuant to this section for failure to meet Specifications or other Manufacturing Requirements, Keryx will inform BioVectra of the reason in writing. If BioVectra confirms that the Product(s) shall be rejected for failure to meet the Specifications or otherwise fail to conform with the Manufacturing Requirements or the independent testing lab or GMP consultant determines their has been a failure to meet the Specifications or conform with the Manufacturing Requirements, then BioVectra will, at Keryx’s sole option (i) expeditiously replace the Product, at

If BioVectra does not agree with Keryx’s rejection of the Products, the difference of opinion shall be first negotiated in good faith by the Parties through their quality assurance representatives, who will attempt in good faith to resolve any such disagreement and Keryx and BioVectra will follow their respective SOPs to determine the conformity of the Product to the Manufacturing Requirements. If such dispute is not resolved within [***] days after BioVectra’s receipt of Keryx’s written notice of its disagreement, the Parties shall submit such dispute to a mutually acceptable independent third party laboratory for such laboratory’s determination as to whether Product meets or fails to meet Specifications and/or mutually acceptable independent GMP consultant in the case of an alleged failure to comply with GMP or any of the other Manufacturing Requirements, as appropriate. The laboratory and consultant, as applicable, must be of recognized standing in the industry, and consent to the appointment of such laboratory and consultant will not be unreasonably withheld or delayed by either Party. Such laboratory will use the test methods contained in the applicable Specifications. The determination by the third party laboratory will be final binding on the Parties absent manifest error on the laboratory’s part, in which event the laboratory will again run the test or the Parties will promptly select another third party laboratory meeting the criteria above to run the test. The Party determined to have incorrectly assessed the Product’s compliance with the Specifications or other Manufacturing Requirements shall bear all of the costs and expenses of the laboratory and/or consultant, as applicable, incurred in making such determination will be paid by the Party against whom the determination is made. The ultimate disposition of non-conforming Product will be the responsibility of Keryx’s quality assurance department.

Keryx will have the responsibility for handling customer returns of the Products. BioVectra will give Keryx any assistance that Keryx may reasonably require to handle the returns.

If a Recall or return results from, or arises out of, a failure by BioVectra to provide Product that conforms to the Specifications or other Manufacturing Requirements, in addition to the amounts payable under this Agreement, BioVectra will also be responsible for the documented out-of-pocket expenses of the Recall or return. If the Parties disagree about whether Product conforms to the Specifications or other Manufacturing Requirements, then they shall be submitted to a neutral expert/

If Product is recalled because the Product manufactured and released by BioVectra deviates from the Specifications or otherwise does not meet the Manufacturing Requirements, Keryx shall have the right to avail itself of the remedies set forth in Section 6.d. above.

Upon termination or expiration of this Agreement, or at any time during the Term, in each case upon Keryx’s written request, BioVectra shall promptly deliver to Keryx, at Keryx’s expense: (a) all unused Keryx Supplied Materials in BioVectra’s (or any of its Affiliate’s) possession or control; (b) all documentation and all copies thereof in whatever form or medium in BioVectra’s (or any of its Affiliate’s) possession or control relating to the Product, CMCs, Specifications, or Keryx Technology or Improvements other than any documentation which BioVectra must retain for such period of time as required by Applicable Law (as to which copies shall be provided to Keryx); and (c) all other Confidential Information of Keryx and any and all other Records, documents and materials (and all copies thereof) in BioVectra’s (or any of its Affiliate’s) possession or control relating to Product and/or containing any Confidential Information of Keryx other than any Confidential Information which BioVectra must retain for such period of time as required by Applicable Law (as to which copies shall be provided to Keryx); provided, however, that the provisions of this Agreement relating to such Confidential Information shall apply to such Confidential Information for so long as it is so retained notwithstanding the expiration or termination of this Agreement.

Inventories. Upon expiration or termination of this Agreement, Keryx at its discretion (i) may obtain from BioVectra any existing inventories of Product ordered under this Agreement that conforms to the Specifications and the other Manufacturing Requirements, at the price for such Product set forth in the Agreement; and (ii) may either (A) purchase any such Product in process held by BioVectra as of the date of the termination, at a price to be mutually agreed (it being understood that such price will reflect, on a pro rata basis, work performed and non-cancelable out-of-pocket expenses actually incurred by BioVectra with respect to the manufacture of such in-process Product); or (B) direct BioVectra to dispose of such material at Keryx’s cost.

Governing Law; Exclusive Jurisdiction/Venue. The rights and obligations of the Parties under this Agreement, and any disputes arising out of or relating to this Agreement, shall be governed by and interpreted in accordance with the laws of the state of [***], without regard to application of any conflicts of laws provisions that would otherwise apply the substantive law of any other jurisdiction. The Parties expressly reject any application to this Agreement of (a) the United Nations Convention on Contracts for the International Sale of Goods; and (b) the 1974 Convention on the Limitation Period in the International Sale of Goods, as amended by that certain Protocol, done at Vienna on April 11, 1980. Any legal action or proceeding concerning the validity, interpretation and enforcement of this Agreement, matters arising out of or related to this Agreement or its making, performance or breach, or related matters will be brought exclusively in the state and federal courts located in the [***]. The Parties consent to the exclusive

Relationship of Parties. The relationship of BioVectra to Keryx under this Agreement is intended to be that of independent contractor. Nothing contained in this Agreement is intended or is to be construed so as to constitute BioVectra and Keryx as employer/employee or principal/agent, or the employees or the agents of any Party hereto as employees or agents of the other Party hereto. Neither Party hereto has any express or implied right or authority under this Agreement to assume or create any obligations on behalf of or in the name of the other Party or to bind the other Party to any contract, agreement, or undertaking with any third party, other than the successors and permitted assigns of the respective Parties hereto.

Assignment. This Agreement may not be assigned or otherwise transferred by either Party without the prior written consent of the other Party; provided, however, that either Party may, without such consent, but with notice to the other Party, assign this Agreement, in whole or in part, (i) in connection with the transfer or sale of all or substantially all of its assets or the line of business or Product to which this Agreement relates; (ii) to a successor entity or acquirer in the event of a merger, consolidation or change of control; or (iii) to any Affiliate. Any purported assignment in violation of the preceding sentence will be void. Any permitted assignee will assume the rights and obligations of its assignor under this Agreement. This Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective permitted successors and assigns. No transfer or assignment will relieve the transferor or assignor of any liability or obligations hereunder. BioVectra may not subcontract with any third party, including any Affiliate of BioVectra, to perform any of its obligations under this Agreement or the Quality Agreement without the prior written consent of Keryx. BioVectra will be solely responsible for the performance of any permitted subcontractor, and for costs, expenses, damages, or losses of any nature arising out of such performance as if such performance had been provided by BioVectra itself under this Agreement. BioVectra will cause any such permitted subcontractor to be bound by, and to comply with, the terms of this Agreement, as applicable, including all confidentiality, quality assurance, regulatory and other obligations and requirements of BioVectra set forth in this Agreement.

Severability. In the event any provision of this Agreement shall be invalid, void, illegal, or unenforceable, the remaining provisions hereof nevertheless will continue in full force and effect without being impaired or invalidated in any way. Each provision in this Agreement is independent and severable from the others, and no provision will be rendered unenforceable because any other provision is found by a proper authority to be invalid or unenforceable in whole or in part. If any provision of this Agreement is found by such an authority to be invalid or unenforceable in whole or in part, such provision will be changed and interpreted so as to best accomplish the objectives of such unenforceable or invalid provision and the intent of the Parties, within the limits of Applicable Law.

Survival. Expiration or termination of this Agreement for any reason will not relieve either Party of any obligation accruing prior to such expiration or termination. Unless expressly specified to the contrary in this Agreement, no remedy referred to in this Agreement is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to in this Agreement or otherwise available under law or at equity. The rights and obligations of the Parties set forth herein which, either explicitly state they survive or by their nature should survive termination or expiration of this Agreement, will survive any such termination or expiration, including without limitation those respecting confidentiality, intellectual property, indemnification, warranties, governing law and jurisdiction and notices.

Notices. All notices under this Agreement shall be in writing and, other than purchase orders and invoices, which may be sent by email, shall be deemed given if sent by certified or registered first class mail, postage prepaid, or commercial express courier (return receipt or confirmation of delivery requested), or by personal delivery to the Party to receive such notices or other communications called for by this Agreement at the following addresses for a Party as shall be specified by such Party by like notice:

Force majeure.     Either Party shall be excused from the performance of its obligations hereunder, or such performance may be delayed, by force majeure causes beyond its reasonable control, including without limitation, acts of God, war, riot, epidemic, fire, flood, insurrection, military authorities, or failure of transportation or communication (“force majeure”), provided that if such nonperformance continues for more than [***] days, the other Party may terminate the Agreement upon written

Limited Liability. Except in the case of a Party’s indemnification obligations hereunder, breach of the confidentiality or intellectual property provisions of this Agreement, or gross negligence or willful misconduct (all the foregoing, the “Exceptions”), in no event shall either Party be liable to the other Party for lost profits, loss of goodwill, or any special, indirect, consequential or incidental damages, however caused and on any theory of liability, arising in any way out of the Agreement. This limitation shall apply even if a Party has been advised of the possibility of such damages, and notwithstanding any failure of essential purpose of any limited remedy. Except for cases of Exceptions, a Party’s total liability under this Agreement shall not exceed the greater of (i) [***], which represents [***], or (ii) the amounts paid and payable by Keryx under this Agreement in the full [***] period preceding the date when the liability in question first arose. The limitations set forth herein shall not apply to claims for (i) death or personal injury caused by a Party’s negligence; or (ii) a Party’s fraud or fraudulent misrepresentation.

Third Party Beneficiaries. Other than Indemnitees with regard to indemnification under Section 7.c., nothing in this Agreement, express or implied, is intended to confer upon any third party any rights, remedies, obligations or liabilities.

Further Actions. BioVectra agrees to execute, acknowledge and deliver such further instruments, and to do all such other acts, requested by Keryx as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

Public Statements. Except to the extent required by applicable law or regulation or the rules of any stock exchange or listing agency, BioVectra will not make any public statement or release concerning this Agreement or the transactions contemplated by this Agreement, or use Keryx’s name or the name of any Affiliate of Keryx in any form of advertising, promotion or publicity, without obtaining the prior written consent of Keryx.

Entire Agreement, Modification, Waivers. This Agreement, which includes the Appendices and Exhibits attached hereto (including the Quality Agreement) that are incorporated herein by reference, and any purchase orders issued by Keryx and

Counterparts; Facsimile/PDF Signatures. This Agreement may be executed in counterparts, each of which shall be an original and all of which shall constitute one and the same instrument. Executed signatures pages to this Agreement may be delivered by facsimile or a portable document format (PDF) copy sent by e-mail and such facsimiles or PDFs shall be deemed as if actual signature pages had been delivered.
