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.

c. 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.

d. 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.

e. 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

16

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).

f.

g. 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).

h. 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.

j. 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.

9. General Provisions

a. 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.

b. 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.

c. 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.

d. 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.

e. 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.

f. 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:
