Any services requested that are beyond the activities related to 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. The Parties will enter into a separate written agreement for any such ad hoc services. For purposes of clarity, BioVectra’s standard FTE rates for services are set out in Appendix 1.

As Keryx plans to [**], Keryx shall have [**] from date of release 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 BioVectra’s sole cost and expense, including the cost of any Keryx Supplied Materials, according to a schedule to be agreed upon between the Parties; (ii) Rework or Reprocess the Product, at BioVectra’s cost and expense, so that the Batch can be deemed to have been manufactured in compliance with the Manufacturing Requirements; or (iii) refund in full the fees and expenses paid by Keryx for such Batch, including the cost of any Keryx Supplied Materials. Moreover, the Parties will meet to discuss, evaluate and analyze the reasons for and implications of the failure to comply with the Manufacturing Requirements.

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 [**] 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/laboratory for binding resolution pursuant to the procedures set forth in Section 4.e. above.

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 4.d. above.

Confidential Information; Intellectual Property

Each of the Parties shall protect all information (“Confidential Information”) supplied or revealed to it by the other Party pursuant to this Agreement, and shall not directly or indirectly, disclose to any third party the other Party’s Confidential Information without the prior written consent of the such other Party or use such information except in the case of BioVectra to perform its obligations pursuant to this Agreement and in the case of Keryx to exercise its rights under this Agreement. Confidential Information shall include any and all non-public scientific, technical, financial regulatory or business information, or data or trade secrets in whatever form (written, oral or visual) that is furnished or made available by the disclosing Party to the other Party, as the receiving Party whether marked in writing, or communicated in visual or oral form. Confidential Information of Keryx includes (i) Keryx Supplied Materials, Keryx Technology and Improvements; (ii) development and marketing plans, regulatory and business strategies, financial

information, and forecasts of Keryx; and (iii) all information of third parties that Keryx has an obligation to keep confidential. Confidential Information of BioVectra includes (i) BioVectra Technology; (ii) capabilities, regulatory and business strategies, financial information; and (iii) all information of third parties that BioVectra has an obligation to keep confidential. Each Party shall take such steps as are reasonably required (including without limitation such steps as such Party takes to protect its own proprietary information) to protect the other Party’s Confidential Information from unauthorized disclosure or use. Product, Records and other reports and information provided by, or on behalf of, BioVectra to Keryx shall be deemed Confidential Information of Keryx, as to which Keryx shall be deemed the disclosing Party for purposes of this Agreement. The Parties acknowledge and agree that BioVectra and its employees shall have access to Confidential Information of Keryx (which may include information from its Affiliates, its licensors and third party business partners). For purposes of this Agreement, the terms of this Agreement shall be deemed to be Confidential Information of both Parties. Confidential Information also includes third-party confidential information supplied by receiving Party to disclosing Party hereunder.

Nothing in this Section 7 shall be construed to impose a confidentiality obligation on a Party in connection with any Confidential Information to the extent such information can be shown by clear and convincing evidence: (i) is at the time of disclosure already known to the receiving Party (as clearly established by such Party’s prior written records); (ii) is at the time of disclosure or subsequently becomes part of the public domain through no fault, act or omission of the receiving Party; (iii) is subsequently disclosed to the receiving Party by a third party whose receipt and disclosure of such Confidential Information does not, constitute a violation of any confidentiality obligation; or (iv) is independently developed by the receiving party by employees having no access to or knowledge of Confidential Information received. Further, a receiving Party shall be entitled to disclose the disclosing Party’s Confidential Information that is required by a court or government agency to be disclosed; provided that the receiving Party shall promptly provide the disclosing Party notice in writing of any proposed disclosure under this subsection and an opportunity to object to the disclosure or seek confidential treatment thereof. If so requested, the receiving Party shall provide reasonable assistance in opposing such disclosure or seeking a protective order or other limitations on disclosure. If, after providing such notice and assistance as required herein, the receiving Party remains legally required to disclose any Confidential Information, the receiving Party shall disclose no more than that portion of the Confidential Information which, on the advice of the receiving Party’s legal counsel, is require to be disclosed and, upon the disclosing Party’s request, shall use commercially reasonable efforts to obtain assurances from the applicable court or agency that such Confidential Information will be afforded confidential treatment. Receiving Party may provide disclosing Party’s Confidential Information to its Affiliates, and to its and their directors, employees, consultants, contractors and agents; provided, however, that (i) any such Affiliates, directors, employees, consultants, contractors and agents are bound by written obligations of confidentiality with respect to the disclosing Party’s Confidential

Information that are at least as restrictive as those set forth in this Agreement; (ii) receiving Party remains liable for the compliance of such Affiliates, employees, consultants, contractors and agents with such obligations; and (iii) in the case of BioVectra as the receiving Party, such disclosure is only to the extent necessary for BioVectra to carry out its obligations under this Agreement. Furthermore, Keryx may disclose Confidential Information of BioVectra relating to the development and/or manufacture of Product to entities with whom Keryx a has (or may have) a marketing and/or development collaboration and/or development collaboration (provided that Keryx shall not provide any Confidential Information regarding the BV [**] to potential marketing and/or development collaborators without the prior consent of BioVectra) or to bona fide actual or prospective underwriters, investors, lenders or other financing sources or to potential acquirers of the business to which this Agreement relates, and who in each case have a specific need to know such Confidential Information and who are bound by a like obligation of confidentiality and restrictions on use.

Keryx Technology. All rights to and interests in Keryx Technology (including all intellectual property rights therein) will remain solely with Keryx and no right or interest therein is transferred or granted to BioVectra under this Agreement. BioVectra acknowledges and agrees that it does not acquire a license or any other right to Keryx Technology except for the limited purpose of carrying out its duties and obligations under this Agreement and that such limited, non-exclusive, license will expire upon the completion of such duties and obligations or the termination or expiration of this Agreement, whichever is the first to occur.

BioVectra Technology. All rights to and interests in BioVectra Technology will remain solely in BioVectra and, except as otherwise set forth in this Agreement, no right or interest therein is transferred or granted to Keryx under this Agreement. Except with respect to the [**], BioVectra hereby grants to Keryx [**] right and license to Keryx and its Affiliates to use and modify BioVectra Technology to research, develop, manufacture, have manufactured, distribute, offer for sale, sell, market, and otherwise dispose of Product.

Improvements. BioVectra agrees (i) to promptly disclose to Keryx all Improvements related to Keryx Technology; (ii) that all Improvements related to Keryx Technology (and all intellectual property rights related thereto) will be the sole and exclusive property of Keryx; and (iii) that BioVectra will assign and does assign all Improvements related to Keryx Technology (and all intellectual property rights related thereto) to Keryx (or its designee) without additional compensation to BioVectra. BioVectra will take such steps as Keryx may reasonably request (at Keryx’s expense) to vest in Keryx (or its designee) ownership of the Improvements related to Keryx Technology (and all intellectual property rights related thereto). In furtherance of the foregoing, BioVectra shall, upon request by Keryx, promptly undertake and perform (and/or cause its Affiliates and its and their respective employees and/or contractors to promptly undertake and perform, as applicable) such further actions as are reasonably necessary for Keryx to perfect its right, title and interest in and to any such Improvements (and all intellectual property rights

associated therewith), including by causing the execution of any assignments or other legal documentation, and/or providing Keryx or its patent counsel with reasonable access to any employees or contractors who may be inventors of such Improvements (and any intellectual property rights associated therewith).

Non-Exclusive License. Except with respect to the [**], BioVectra agrees to grant to Keryx [**] license, to use Improvements made solely by BioVectra personnel and that relate solely to BioVectra Technology or the Confidential Information of BioVectra to research, develop, manufacture, have manufactured, distribute, offer for sale, sell, market, and otherwise dispose of Product.

Patent Filings. Keryx will have the exclusive right and option, but not the obligation, to prepare, file, prosecute, maintain and defend, at its sole expense, any patents that claim or cover the Improvements (and any intellectual property rights associated therewith).

Technology Transfer. If Keryx elects to manufacture Product, or to have Product manufactured by a third party, then BioVectra will provide to Keryx or its designee, all manufacturing information, including documentation, technical assistance, materials and cooperation, excluding the BV Drying Technology as Keryx or its designee may reasonably require in order to manufacture Product. Keryx will compensate BioVectra for such assistance at the hourly-rate(s) set forth in Appendix 1.

Trademarks and Trade Names. Keryx and BioVectra hereby acknowledge that neither Party has, nor shall either Party acquire by reason of this Agreement, any interest or rights of use in any of the other Party’s trademarks, trade names, designs or logos unless otherwise expressly agreed in writing by the Parties. Notwithstanding the foregoing, Keryx shall have the right to use the BioVectra’s trademarks, trade names, designs or logos, as may be required by Applicable Law (or as may otherwise be reasonably necessary) in connection with obtaining and maintaining Health Registrations for the Products or in connection with marketing and sale of Product (e.g., listing BioVectra as the manufacturer of product on the packaging, if applicable).

No Rights/Remedies. All Keryx Confidential Information which BioVectra or its personnel shall obtain or be given access pursuant to or in connection with this Agreement shall be and remain the sole property of Keryx, and BioVectra shall have no rights or interests (except as expressly provided herein) to or in such Confidential Information. The Parties recognize and agree that an action for damages may be inadequate to enforce the restrictions and rights set forth in this Section 7. BioVectra’s breach or threaten breach of this Section 7 may cause immediate and irreparable harm and unascertainable damages to Keryx. The Parties agree that in the event of any breach or threatened breach of this Section 7, Keryx shall be entitled, in addition to any other right or remedy it may have at law or in equity, to seek and obtain injunctive relief, without the need to post bon or other security or show monetary damages.

Term and Termination

The Agreement will commence on the Effective Date and terminate on October 1, 2019, unless terminated earlier as provided herein (“Term”). Notwithstanding the above, the Agreement will not terminate until any remaining outstanding purchase orders or binding commitments are fulfilled. Any extension of the Term must be mutually agreed to in writing.

This Agreement may be terminated at any time upon the mutual consent of the Parties.

Either Party may terminate this Agreement for breach of any of its material provisions upon [**] prior written notice to the other, if during such [**] notice period the default is not corrected to the reasonable satisfaction of the non-defaulting Party. In addition, either Party may terminate this Agreement by giving the other Party at least sixty (60) days written notice if such other Party has entered into or committed any act of liquidation, bankruptcy, insolvency, receivership, or assignment for the benefit of creditors, to the extent such act is permitted by law.

Effects of Termination or Expiration. Upon expiration or termination of this Agreement the following shall apply:

Except where termination is due to the uncured material breach of Keryx, Keryx shall have the option (in its discretion) to either: (A) cancel all outstanding purchase orders; or (B) require BioVectra to continue to supply Product in accordance with purchase orders submitted prior to the termination or expiration of this Agreement (which supply shall be in accordance with the terms and conditions of this Agreement).

ii.

Except where termination is due to the uncured material breach of Keryx, at the election of Keryx, BioVectra shall continue to supply Product to Keryx on the terms and conditions set forth herein until the earlier of: (i) such time as Keryx notifies BioVectra that Keryx has achieved alternative manufacturing arrangements which are presently capable of manufacturing the applicable Products, or (ii) [**].

vi.

Upon the written request of Keryx, BioVectra shall return to Keryx (or its designee), or destroy, all remaining Keryx Supplied Materials, as requested by Keryx. BioVectra shall perform any such destruction (if destruction was requested by Keryx) in compliance with all Applicable Law.

(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; 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; 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.

General Provisions

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 [**], 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 jurisdiction of those courts and waive any objection to the propriety or convenience of such venues.

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 any 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 Keryx may, without such consent, but with notice to BioVectra, 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 [**], the other Party may terminate the Agreement upon written notice. The Party affected by any force majeure will promptly notify the other Party, explaining the nature, details and expected duration of the force majeure. Such Party will also notify the other Party from time to time as to when the affected Party reasonably expects to resume performance in whole or in part of its obligations under this Agreement, and to notify the other Party of the cessation of any such force majeure. A Party affected by force majeure will use its reasonable efforts to remedy, remove, or mitigate such force majeure and the effects of it with all reasonable dispatch. If a Party anticipates that force majeure may occur, such Party will notify the other Party of the nature, details and expected duration of the force majeure. Upon termination of the force majeure, the performance of any suspended obligation or duty will promptly recommence.

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, 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.

Third Party Beneficiaries. Other than Indemnitees with regard to indemnification under Section 5.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 accepted by BioVectra constitute the full and entire understanding and agreement of the Parties hereto with regard to the subject matter hereof, and supersede all prior agreements and understandings, written or oral, between the Parties with respect to the such subject matter. This Agreement may not be amended except by a written instrument signed by the Parties hereto. Any delay in enforcing a Party’s rights under this Agreement, or any waiver as to a particular default or other matter, will not constitute a waiver of such Party’s rights to the future enforcement of its rights under this Agreement, except with respect to an express written waiver relating to a particular matter for a particular period of time signed by an authorized representative of the waiving Party, as applicable. The section headings are included solely for convenience of reference and will not control or affect the meaning or interpretation of any of the provisions of this Agreement.

Counterparts; Facsimile 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.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed by their duly authorized representatives as of the date first above written.

BioVectra shall perform such true-up by either (i) for underpayments, sending to Keryx at [**] an associated invoice, (ii) for overpayments, crediting Keryx against the Project Payment and adjusting the amount owed by Keryx against the Estimated Total Project Cost accordingly. For the avoidance of doubt, the True-up Date for each Supply Term is as follows:

(A)

[**] for Supply Term 1;

(B)

[**] for Supply Term 2;

(C)

[**] for Supply Term 3;

(D)

[**] for Supply Term 4;

(E)

Purchase orders will be confirmed by BioVectra for acceptance and delivery timing and BioVectra shall not reject any Keryx purchase orders for Product that fall within the capacity requirements of this Agreement.

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 and types 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 in each purchase order and deliver such quantities in accordance with the mutually agreed upon delivery schedule. For the purposes of this Agreement, “delivery” of Product means release of Product and provision of documentation by BioVectra pursuant to Section 3.b. BioVectra shall, within [**] of receipt of a purchase order, confirm in writing: (i) that the purchase order has been accepted and (ii) the scheduled manufacturing campaign months. BioVectra shall be required to accept the purchase orders (or portions thereof, as applicable) which are provided to BioVectra in accordance with the terms and conditions of this Agreement. In the event that the terms of any purchase order or purchase order acceptance are not consistent with this Agreement, the terms of this Agreement shall prevail.

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 8.c.iii. and for termination by BioVectra under Section 8.c.) BioVectra agrees that it will not, directly or with or on behalf of a third party, develop, market, advertise, promote, manufacture, supply, distribute, [**] (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 not to use any Keryx Technology, Improvements or Confidential Information of Keryx shall survive the expiration or termination of this Agreement.

Once a purchase order has been received, the Parties, in consultation with [**]will coordinate the planning schedule for the API Facility for the corresponding Supply Term. Thereafter, BioVectra will develop a manufacturing schedule for the AFI Facility and, after providing initial confirmation of the manufacturing campaign months pursuant to Section 2.h., will provide Keryx, [**] prior to commencement of manufacture, the expected delivery dates for Product. BioVectra will credit Keryx, [**]percent ([**]%) of the purchase order price any quantity of Product delivered outside [**] of the expected delivery date. If there is a dispute related to Product late delivery, the Parties will work in good faith towards prompt resolution.

The Parties will enter into good faith negotiations of the agreement governing the Expansion Project (the “Expansion Agreement”). The Expansion Agreement will account for a credit equal to the Project Payment to be applied against the actual cost of the Expansion Project.

After Product delivery, Keryx will review the documentation received pursuant to Section 3.b. and, within [**] calendar days, either (i) provide a written authorization to ship, or (ii) reject Product in accordance with Section 4.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 LSU or the API Facility to Keryx’s assigned designation until either it has received Keryx’s written authorization to ship or more than [**] calendar days have passed since Product delivery.
