|Valid Claim | An issued claim of a patent, which claim has not expired, lapsed, been abandoned, been cancelled, been revoked, been held invalid or unenforceable by a court of competent jurisdiction in a final and non-appealable or unappealed judgment, and has not been admitted to be invalid or unenforceable through reissue, re-examination, disclaimer or otherwise.
|----------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2 | Grant of license rights.
|- | ------------------------



|2.1 | Licenses.Subject to the terms and conditions of this Agreement, SDI hereby grants to Avigen an exclusive, sublicenseable (subject to compliance with and as set forth in Section 2.3) license under the Licensed Patents and the Licensed Know-How to develop, have developed, use, have used, market, have marketed, offer for sale, sell, have sold, import and have imported the Licensed Products in the Territory. For the avoidance of doubt, such license shall not include any right to manufacture or have manufactured the Licensed Product.  (However, for clarity, Avigen shall have those manufacturing rights that are set forth in Sections 4.5.5 and 10.4.2 and in Supply Terms Sections 6.5 and 8.3, under the circumstances referred to in such Section and Supply Terms Sections.)
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.2 | Formal Licenses for Recordation Purposes Only.  The Parties shall -- if requested in writing by Avigen -- execute such formal license recordation documents as may be necessary or appropriate for registration with Patent Offices and other relevant authorities in particular countries of the Territory.  If any such license recordation document conflicts with this Agreement, this Agreement shall prevail, govern and control, in all cases.  Prior to the execution of the formal license recordation document(s) (if any) referred to in this Section 2.2, the Parties shall so far as possible have the same rights and obligations towards one another as if such formal license recordation document(s) had been executed and recorded.  The Parties shall use reasonable endeavors to ensure that, to the extent permitted by relevant authorities, this Agreement
shall not form part of any public record, subject to Section 3.7.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.3 | Sublicensing.  Avigen shall be entitled to grant sublicenses of its rights under this Agreement through one or more tiers of sublicensees without consent, including to its Affiliates and to Third Parties, provided that all of the following are satisfied:
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.3.1 | Avigen notifies SDI in writing the identity of each Sublicensee within thirty (30) days after granting the sublicense.
|----- | ----------------------------------------------------------------------------------------------------------------------



|2.3.2 | The sublicense shall include obligations on the Sublicensee which are sufficient to allow Avigen to fulfil its obligations under this Agreement (e.g., the Sublicensee shall report its Net Sales to Avigen on a timeline that enables Avigen to make any royalty payments on the Sublicensees Net Sales required by this Agreement in a timely manner).
|----- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.3.3 | The sublicenses shall terminate automatically on termination of this Agreement under Section 10.2.3 for Avigens uncured material breach or insolvency or under Section 10.2.2 by Avigen at will.  Avigen shall notify its Sublicensees promptly (within 30 days) after any such termination of this Agreement.  If within 30 days of such notification a Sublicensee notifies SDI in writing that the Sublicensee wishes its sublicensed rights to continue as a direct license from SDI for the then remainder of the term of its sublicense, SDI may grant to the Sublicensee a direct license on the same terms as the sublicense provided such terms are in SDIs reasonable view no more onerous and no less favorable to SDI than the terms of this Agreement.

|2.3.5 | Avigen shall remain responsible to SDI for any act or omission of a Sublicensee to the extent it constitutes a breach of the Agreement.
|----- | ---------------------------------------------------------------------------------------------------------------------------------------



|2.4 | Distributors.  In addition to its right to grant sublicenses, without granting a sublicense, Avigen may appoint any one or more Affiliate(s) or Third Party(ies) to distribute and sell Licensed Products (any such Third Party that is so appointed (but not any Affiliate that is so appointed), a Distributor) in one or more country(ies) of the Territory provided that all of the following are satisfied:
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.4.1 | Avigen notifies SDI in writing the identity of each Distributor within thirty (30) days after granting the Distributorship;
|----- | ---------------------------------------------------------------------------------------------------------------------------



|2.4.2 | The Distributors appointment shall terminate automatically on termination of this Agreement under Section 10.2.3 for Avigens uncured material breach or insolvency or under Section 10.2.2 by Avigen at will.

|----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.4.3 | Within 30 days after the appointment of a Distributor, Avigen shall provide to SDI a true copy of such portions of the distribution agreement as are necessary to verify compliance with this Section 2.4.

|2.4.4 | Avigen shall remain responsible to SDI for any act or omission of a Distributor to the extent it constitutes a breach of the Agreement.
|----- | ---------------------------------------------------------------------------------------------------------------------------------------



|2.5 | Reservation of rights.  No right, title or interest is granted, whether expressly or by implication, to any Patents or Know-How owned by SDI, except for the rights and licenses expressly granted under this Agreement under the Licensed Patents and Licensed Know-How.  SDI reserves to itself all rights not expressly granted under this Agreement.  This Agreement shall not be deemed to restrict SDI from exploiting any of its rights not expressly granted to Avigen under this Agreement.  Without prejudice to the generality of the foregoing SDI reserves all rights under any and all Patents outside the Territory that are x-Territory counterparts to the Licensed Patents, and under the Licensed Know-How outside the Territory;provided,however, that SDI
shall not grant any license or other right to practice outside the Territory under Licensed Patent counterparts outside the Territory, or under Licensed Know-How, with respect to Tolperisone Products, which license covers activities to supply any Tolperisone or Tolperisone Product into the Territory or would permit the licensee to supply any Tolperisone Product into the Territory.

For purposes of (b), market share shall be measured by number of prescriptions filled (or units sold), by reference to IMS data, or an at-least similarly reputable, validated audit source.  This
Section 4.3.3 (including the reductions and measurements provided below) shall apply with respect to all IR Products taken together, and separately to all CR-Qualified Products taken together.  IR Products and CR-Qualified Products shall not be aggregated for purposes of measuring the[*]market share described above.

|4.3.5.1 | The Net Sales for the purpose of determining royalties on sales of the Combination Product shall be calculated by multiplying Net Sales of such Combination Product by the fraction A/(A+B) where A is either: (a) the price to Third Party end users of the Tolperisone Product component of the Combination Product when sold separately, should Tolperisone Products be sold separately in the applicable country; or (b) the fair market value of the portion of the Combination Product containing the Tolperisone Product included in such Combination Product, as such fair market value is determined in good faith by the Parties, if Tolperisone Products are not sold separately in the applicable country, and B is either (c) the price to Third Party end users of product containing the other active ingredients of the Combination Product when sold separately should such active
ingredients be sold separately in the applicable country; or (d) the fair market value of the portion of the Combination Product containing the other active ingredients, as such fair market value is determined in good faith by the Parties, should such active ingredients not be sold separately in the applicable country.

|4.3.5.2 | Regarding list prices when sold separately referred to in Section 4.3.5.1, if these are available for different dosages of Tolperisone and the other active ingredients than their dosages that are included in the Combination Product, then Avigen shall be entitled to make an equitable (typically, proportional) adjustment to the list prices in calculating the royalty-bearing Net Sales of the Combination Product.

4.3.6           Anti-Bundling.  If Avigen (or its Affiliate or Sublicensee) prices a bundle of products, and the bundle includes Licensed Product, then (for purposes of calculating royalties due under this Section 4.3) Net Sales of the Licensed Product when sold as part of the bundle shall be discounted relative to the list price of that Licensed Product when sold separately, if at all, by no more than the average percentage discount of all products included in the bundle, calculated as follows:

Average percentage discount on a particular bundle of products  =  1 - (A/B) x 100,



where A equals the total discounted price of the bundle of products, and B equals the sum of the undiscounted bona fide list prices or fair market values as established by other evidence of each unit of every product in such bundle.



For purposes of this Section 4.3.6, a bundle is a group of products for which Avigen (or its Affiliate or Sublicensee) establishes prices with individual customers as a group or package, such that the prices for all products in the group are negotiated together.  (This practice is sometimes referred to as portfolio pricing.)



|4.3.7 | Payment Schedule.  Avigen shall pay SDI the royalty required under this Section 4.3 within[*]days of the end of each Quarter in respect of sales of Licensed Product made and Net Sales generated during such Quarter.
|----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.3.8 | Sales to Related Parties as End Users.  Sales to Third Parties are presumed to occur at arms length.  Net Sales regarding these sales in general require no special adjustments to ensure arms-length pricing.  In cases, however, where Avigen or its Affiliate or Sublicensee sells Licensed Product to an entity in which any of them has a[*]and such entity (a) is not marketing or clinically testing Licensed Product, and (b) is the end user of such Licensed Product (Related Entity End User), then the value of Net Sales for the units sold to the Related Entity End User shall be equal to the average per-unit Net Sales price for Licensed Product in the country of the Related Entity End User.  (To avoid any doubt, the sales to the Related Entity End User itself shall be
excluded from the calculation of the average per-unit Net Sales value, which shall be based on the other sales of the applicable Licensed Product in that country.)

|4.4 | Clinical Supply Price.  Supply of Finished Product to Avigen and made available by Avigen on a free of charge basis for the purposes of conducting clinical trials necessary for obtaining Regulatory Approvals and/or label expansions for Licensed Products that have already been approved, or for use in marketing studies, shall be at the price set forth in Schedule 5 for the Current IR Product and corresponding placebos, and the Current CR Product, and[*]If for such clinical purposes Avigen requires supply of any differently formulated IR Product or CR-Qualified Product (for example, if the FDA requires a modification to either of them), then SDI shall supply Avigen at a price that reflects any increase in SDIs Fully Burdened Manufacturing Cost to manufacture the differently formulated
version, relative to SDIs Fully Burdened Manufacturing Cost as of the Commencement Date, to manufacture the Current IR Product and the Current CR Product.  To avoid any doubt, nothing in this Section 4.4 is intended to make Avigen responsible in any way (on a pass-through basis through the supply price or otherwise) for any capital improvements that may be required for SDI to manufacture Licensed Products to supply Avigen hereunder.

4.5       Commercial Supply Price.  In addition to the sums set out in clauses 4.1, 4.2, 4.3 and 4.4, and in consideration of all supply of Finished Product to Avigen other than for the purposes of conducting clinical trials necessary for obtaining or expanding Regulatory Approvals, Avigen shall pay SDI the following transfer prices, calculated and payable as follows:



|4.5.1 | An advance payment of[*]of Finished Product for the IR Product, and a price per pack of the CR-Qualified Product determined in accordance with Section 4.5.4, in each case delivered to Avigen or its designee (Advance Payment); and

|4.5.2 | A payment calculated as Net Sales in any Quarter multiplied by the Transfer Price Percentage (Further Payment); and
|----- | ---------------------------------------------------------------------------------------------------------------------



|4.5.3 | The payment required in Section 4.5.2 shall be reduced by the amount of the Advance Payment attributable to that same Quarter (i.e., by[*]of Licensed Product sold that Quarter to generate that Quarters Net Sales), and the payment of Section 4.5.2 is only required to actually be made to the extent the Further Payment in any Quarter exceeds the Advance Payment attributable to that same Quarter.  To the extent the Advance Payment attributable to a Quarter (i.e.,[*]of such Licensed Product sold that Quarter to generate that Quarters Net Sales) exceeds the Further Payment for that Quarter, Avigen is entitled to credit the amount by which such Advance Payment exceeds such Further Payment (the Excess) against subsequent payments due SDI
hereunder, or, if no further payments are due SDI hereunder SDI shall refund to Avigen the Excess within[*]after requested in writing by Avigen.

|4.6.1 | The Advance Payment shall be paid within[*]of delivery in accordance with the Supply Terms.
|----- | -------------------------------------------------------------------------------------------



|4.6.2 | The Further Payment (if any actual payment is required under Section 4.5.3) shall be made within[*]of the end of the Quarter to which such payment is attributable.  The Further Payment shall be accompanied by an accurate and reasonably detailed statement setting out Avigens calculation of the Further Payment for such Licensed Products in accordance with clause 4.5 above based on actual invoiced gross sales (and deductions in accordance with the definition of Net Sales), as well as reconciling Advance Payments made with Further Payments due in that Quarter.
|----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.7 | Late Payments.  Any payment which is not paid within the time frames specified in this Article 4 shall bear interest, to the extent permitted by applicable law, at the prime rate of the Bank of America (or if it no longer exists under such name, the entity succeeding to all or substantially all of its banking assets) as reported in theWall Street Journal(or its successor) from time to time, calculated on the number of days such payment is overdue.

|4.8 | Withholding.  If provision is made in law or regulation of any country for withholding of taxes of any type, levies or other charges with respect to the signature fee, milestone payments, royalties or other amounts payable under this Agreement (including, to avoid any doubt, the Supply Terms) to SDI, then Avigen shall be entitled to deduct such taxes, levies and other charges from such amounts payable under this Agreement.  Avigen shall promptly pay such tax, levy or charge for and on behalf of SDI to the proper government authority.  Avigen shall thereafter promptly (within sixty (60) days) furnish SDI with receipt of payment.

|4.10 | Records and Audits.

|4.10.1 | Avigen shall keep and ensure that its Affiliates and Sublicensees keep complete and accurate records of its inventory of Licensed Products, and sales and other dispositions (including use in clinical trials, or provision on a compassionate use basis or as marketing samples) of the Licensed Products including all such records that may be necessary for the purposes of calculating all payments due under this Agreement. SDI shall have the right to have a certified public accounting firm that is nationally recognized in the US examine such records.  Avigen shall make such records available for inspection by SDIs chosen such accounting firm at Avigens premises in the US on reasonable notice during regular business hours.
|------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.10.2 | Accordingly, at the expense of SDI no more than once per year, SDI has the right to have such certified public accountant from a nationally recognized accounting firm perform on behalf of SDI an audit -- conducted in accordance with US generally accepted accounting principles -- of such books and records of Avigen, its Affiliates and its Sublicensees, as are deemed necessary by the independent public accountant to report on Net Sales for the period or periods requested by SDI and the correctness of any report or payments made under this Agreement (all subject to Section 4.10.3).

|4.10.5 | Audit results shall be shared by Avigen and SDI.  However, no information that is not necessary to demonstrate any under- or over-payment will be disclosed by the auditor to SDI (nor is this information otherwise required under this Section to be shared with SDI).  The auditor shall be under written obligations to Avigen of confidentiality and non-use (other than uses required by this Section 4.10).

|5 | Development and Regulatory.
|- | ---------------------------



|5.1 | Joint Committee.  Promptly after the execution of this Agreement the Parties will form a joint information sharing committee (the Committee).  The Committee shall be made up of an equal number of representatives of each of SDI and Avigen.  It shall include at least one person at the level of Vice President or above from each Party.  The role of the Committee is to provide a regular forum for communication between the Parties.  The Committee is anticipated to be the first place and opportunity for the Parties to discuss any desired elements of collaboration and to consider together any potential amendments to this Agreement with regard to development activities.  Neither Party is required to agree to any such amendments.  Any actual amendments require an authorized officer of each Party to sign in writing the amendment.    The
Committee has no decision-making authority.  The Committee has no power to amend, modify or waive compliance with this Agreement.  The Committee shall meet Quarterly until Launch of the CR-Qualified Product in the US (or, if development of any CR-Qualified Product is abandoned by SDI, Launch of the IR Product in the US) and annually thereafter.

Avigen shall prepare and deliver progress reports regarding Licensed Product development not less than[*]prior to each meeting of the Committee.  SDI shall do the same in time periods when SDI is conducting (including sponsoring) clinical trials of Licensed Products.



Each Party shall have the right to change their representation on the Committee upon not less than[*]written notice to the other Party.  The Committee is not specific to development information sharing.  It also applies to commercialization information sharing.  It is anticipated that as Avigens primary Licensed Product activities shift from development to commercialization, the Parties may wish to update their Committee membership to include people more familiar with commercialization than development (but to be clear, this is voluntary, not required).



|5.2 | Overview and Background.  SDI is seeking to gain Regulatory Approval to market the Current IR Product and Current CR Product in Europe.  To work to achieve this, SDI has conducted certain clinical trials of each of the Current IR Product and the Current CR Product prior to the Commencement Date.  For the Current IR Product, the Parties expect that data from the clinical trials for which SDI already (as of the Commencement Date) has the final reports and final data should enable Avigen to proceed directly to conduct[*].  For the Current CR Product, in contrast, SDI has conducted a PK trial, but not yet any phase II clinical trials on the Current CR Product.  The phase II trial envisaged for the Current CR Product is the Required Phase II CR Clinical Trial, as further described in Section
5.5.  As specified in Section 5.5, Avigen will not be conducting such trial or any similar trial unless it elects in its sole discretion to do so.  It is not possible for Avigen to proceed directly to a Pivotal Trial Program of the

Current CR Product for the US market on the basis of SDIs current clinical data.  Therefore, Avigens clinical development of the Current CR Product -- which is intended by the Parties to begin with a Pivotal Trial Program, and not, except to the extent Avigen agrees in its sole discretion otherwise, any earlier stage trials ([*]) -- depends on the clinical trial of the Current CR Product for which SDI is responsible under Section 5.5, with Avigens consultation and input under such Section.  Avigen shall also be obliged to contribute to a portion of the cost of such trial, solely if and to the extent specified in Section 5.5 with respect to a change to such trial[*]of which Avigen notifies SDI in writing under such Section that[*]Accordingly:  (a) SDI is required to carry out certain further Current CR Product clinical programs as stated in Section 5.5, and an outline of which is attached at Schedule 2 (SDI CR Clinical Program), and (b) other than the obligations for Avigen to confer in a collaborative manner and provide input to SDI to the extent set forth in Section 5.5, Avigens diligence and other obligations for CR-Qualified Products do not begin prior to, and are subject to SDIs successful completion of, the SDI CR Clinical Program, or[*]of a[*]that[*]the[*]that[*]through[*]on the timing and as provided in Section 7.2.3.



The remainder of this Article 5 and Article 6 (except with respect to Avigens obligation to use Diligent and Reasonable Efforts, and SDIs obligations to use such efforts under Section 5.8.3), represent merely a general statement of the allocation of responsibilities among the Parties.  Avigens diligence obligations with respect to these responsibilities are set forth in Article 7.  Nothing in this Article 5 or Article 6 shall be read to modify Article 7 or impose a different or heightened standard on Avigen in lieu of or in addition to those of Article 7.



|5.3 | Avigen Overall Responsibility.  Avigen shall as between the Parties be responsible to: (a) develop and obtain Regulatory Approval for Licensed Product for the Field in the Territory; (b) carry out a Launch in respect of Licensed Product in all countries in the Territory in which it receives Regulatory Approval (and any applicable governmental pricing approval that may  in effect be required for a commercially reasonable product launch); and (c) promote, market, sell or otherwise commercially exploit Licensed Products for the Field in the Territory.  All expenses incurred by Avigen for research, development and commercialization, including all required expenses for toxicology and all expenses for preclinical development, clinical trials, preparing, filing and maintaining INDs and NDAs and other regulatory activities, shall be borne and
paid by Avigen.

If data generated under any such item is submitted by Avigen to a Regulatory Body (whether submitted in a Regulatory Approval Application or in response to a Regulatory Body request or requirement), then Avigen shall reimburse to SDI all fees and expenses paid by SDI under such agreement to the extent they accrued and /or fell due on or after the Commencement Date.  In the case of the document written in the German language referred to in Schedule 7, SDI has provided a written translation of such document into English.  Avigen is entitled to rely on such translation provided by SDI.  As between the Parties, SDI shall be solely responsible for any discrepancies between the German version and the English translation provided by SDI.



|5.5 | SDI CR Clinical Program.  Schedule 2 contains a description of the basic elements of the SDI CR Clinical Program.  The SDI CR Clinical Program shall encompass[*]and that must meet the Phase II Design Standard (the Required Phase II CR Clinical Trial).  Within one hundred twenty (120) days after the Commencement Date, the Parties shall discuss through the Committee a more detailed specification for such program, including protocols to be submitted for Regulatory Body and institutional permissions to conduct the trial, and in particular the design of and the formulation (recognizing that the Parties currently intend it to be the Current CR Product) of the potential CR-Qualified Product which is to be used in such Required Phase II CR Clinical Trial.  These discussions are
intended to explore advice, suggestions and questions Avigen may have regarding the Required Phase II CR Clinical Trial as proposed by SDI and to provide an opportunity for Avigen to give SDI feedback.  However,[*]for[*]the[*]as to the[*]implementation of the Phase II CR Clinical Trial[*]the[*]or[*]of the[*]as[*]as well as the decisions regarding whether or how to conduct any further phase II clinical testing of potential CR-Qualified Products that SDI may choose to undertake to demonstrate whether a particular pharmaceutical composition actually meets

SDI is not required to undertake clinical testing of potential CR-Qualified Products beyond the SDI CR Clinical Program.  However, SDI may choose to do so (at its sole expense).  Avigen will have the obligations as regards an additional formulation (but only if further formulations are required) other than the Current CR Product that is proven in phase II to qualify (at that stage, subject to demonstration to the contrary at a later stage) as a CR-Qualified Product, that are set forth in Section 7.2.3.



|5.6 | Avigen Clinical Trials.  Except for the SDI CR Clinical Program, Avigen shall be solely responsible for the cost of all studies necessary to file for Regulatory Approval of the Licensed Products in the Territory, whether or not such studies are contracted out to a Third Party.  Avigens current plans for its clinical trials of the Current IR Product for the Field are as set forth in Schedule 6.  Such plans are subject to change.  Avigen does not covenant, represent or warrant that its actual clinical program for the Current IR Product will be as set forth in such Schedule.  However, as Avigen develops these plans Avigen will discuss them with SDI through the Committee meetings.  Avigen is not required to obtain SDIs consent to Avigens clinical plans for any Licensed Product.

Regarding the Current CR Product, following completion of the Required Phase II CR Clinical Trial and any further trials of the Current CR Product that are conducted in accordance with Section 5.5 and final reports and analysis of data from such trial(s), Avigen shall decide whether to commence the Pivotal Trial Program with respect to the Current CR Product.  If Avigen in its sole discretion decides not to request the FDA to hold a pre-IND meeting with Avigen[*]following completion of the determination that the Current CR Product is a CR-Qualified Product and availability to Avigen of the final reports from all clinical trials used to demonstrate such status (including the final report from the Required Phase II CR Clinical Trial) in order to seek permission to commence such Pivotal Trial Program, then for so long as (and only for so long

Program with respect to the Current CR Product, the Current CR Product shall only be deemed a CR Product if and for so long as it is demonstrated to meet the standards to be a CR Product in accordance with the definition of such term.



If the Required Phase II CR Clinical Trial is performed on a formulation other than the Current CR Product, then the foregoing paragraph appliesmutatis mutandisto that formulation.  In addition, if SDI presents an alternative formulation timely under Section 7.2.3 with phase II clinical trial data from a trial commensurate with the Required Phase II CR Clinical Trial demonstrating that such formulation at that stage is a CR-Qualified Product (Alternative Formulation), then the foregoing paragraph appliesmutatis mutandisto the Alternative Formulation.  To be clear, the foregoing sentence only applies if the Current CR Product fails in development or is not proven to be a CR-Qualified Product.

Avigen shall file and process all applications for Regulatory Approval in the Territory in its own name and shall be solely responsible for the cost of the filing and processing of all such applications in the Territory, taking such steps and actions as may be necessary and advisable to obtain Regulatory Approval for the Licensed Products in the Territory, including, without limitation, making all applications, requests for authorizations, submissions of information and data, connected with or related to the approval of clinical trials work and Regulatory Approvals for the Licensed Products under this Agreement with the Regulatory Body or other competent authorities of the Territory. Avigen shall provide to SDI copies of a draft summary of all manufacturing data and draft related submissions sufficiently in
advance of submission to such Regulatory Body or authorities to allow SDI reasonable opportunity to comment thereon, and Avigen shall take reasonable account of SDIs comments.  In addition, upon request of SDI, Avigen shall provide to SDI copies of a draft summary of all other data and draft related submissions sufficiently in advance of submission to such Regulatory Body or authorities to allow SDI reasonable opportunity to comment thereon,[*]Avigen is entitled, if it chooses, to provide these copies in electronic form.  SDI shall have the right to receive a copy with regard to any written submission to such Regulatory Body or authority.

|7.2.3 | Reformulations.  If either of the Current IR Product or the Current CR Product does not proceed in development or must be reformulated in order to proceed in development, then Avigen shall meet the diligence goals set forth in Sections 7.2.1 and 7.2.2 and Avigens other diligence obligations under this Agreement with a different IR Product or the CR Trial Formulation, as the case may be.

|7.2.4 | Clarification in Relation to Supply Failures.  Further, any failure by SDI to supply Licensed Products in accordance with the Supply Terms shall extend the timelines of this Section 7.2 by an amount of time equal to any delay resulting from this failure to supply.
|----- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7.3 | Effect of Timelines.  The Parties have agreed timelines for Licensed Product clinical development and regulatory diligence goals for Avigen for the Territory that the Parties consider are reasonable and likely to be consistent with the application of Diligent and Reasonable Efforts.  However, the Parties recognize that Avigens failure to meet any diligence goal set forth in such Sections by the corresponding deadlines set forth in the applicable Section shall not in and of itself constitute a diligence failure nor a material breach of this Agreement for purposes of Section 7.4 so long as Avigen has devoted its Diligent and Reasonable Efforts but despite such efforts it has failed to meet the timelines set forth above.  Furthermore, to the extent that Avigen has devoted its Diligent and Reasonable Efforts, and thereafter complies
with the procedures set forth in Section 7.4 in relation to any failure to achieve a diligence milestone by the corresponding deadline, and carries out any Diligence Plan established in accordance with such Section to address such failure, Avigen shall not be deemed to have materially breached this Agreement by virtue of failure to achieve a Section 7.2 milestone by the corresponding deadline.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|7.4 | Milestone Timeline Meetings; Diligence Plans.  If Avigen fails to meet any of the diligence goals set forth in Section 7.2 by the corresponding deadlines, then SDI may request a meeting with Avigen in writing.  The Committee shall meet within[*]after SDIs written request to discuss the reasons for Avigen not meeting the deadline, how Avigen may overcome any impediments that may have prevented it from achieving any of the diligence goal deadlines, and a reasonable revised timeline for Avigen to achieve the remaining diligence goals applying Diligent and Reasonable Efforts.  Within[*]after the Parties meeting, Avigen shall provide to SDI Avigens written plan for the further development and commercialization of the
applicable Product (the Diligence Plan).  Any Diligence Plan shall take into consideration among other factors (including without limitation regulatory issues) that which is out of the reasonable control of Avigen or its ability to plan for (e.g., serious adverse events, Regulatory Authority-imposed or mandated delays or IRB-imposed or mandated delays).  Avigens Diligence Plans must be reasonably calculated (taking into consideration the foregoing) to promptly meet all remaining diligence milestones set forth in the applicable Section of this Agreement as soon as is reasonably practicable after the original deadlines by the application of Diligent and Reasonable Efforts.  However, while any Diligence Plan will include timelines, each will be focused primarily on activities.  SDI may comment on Avigens Diligence Plan.  If requested by SDI the Parties shall promptly (within[*]after SDIs request) meet to
discuss SDIs comments.  Avigen shall provide to SDI a revised written plan reasonably addressing SDIs concerns within thirty (30) days after any such meeting, and this revised version will be the Diligence Plan.  Once a Diligence Plan is in place, then Avigen shall use Diligent and Reasonable Efforts to carry out the Diligence Plan.  So long as Avigen uses Diligent and Reasonable Efforts to comply with such a Diligence Plan, Avigen shall not be deemed to have been in breach of this Agreement by virtue of the failure to meet a particular diligence milestone set forth in this Agreement as of the Commencement Date by the corresponding deadline.  Any failure by Avigen to use Diligent and Reasonable Efforts to comply with such a Diligence Plan shall be eligible to qualify as a material breach of this Agreement.  However, any evaluation of whether a material breach has occurred must be based on an evaluation of all relevant facts and circumstances.

|8.1 | Ownership.  Any and all right, title and interest to any Patents and Know-How related to Licensed Product created by or on behalf of SDI (or its Affiliates) shall remain owned by SDI.  Any and all right, title and interest to any Patents and Know-How related to Licensed Product created by or on behalf of Avigen (or its Affiliates, Sublicensees or Distributors) shall as between the Parties remain owned by Avigen.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|8.2 | Obtain and Maintain the Licensed Patents.Avigen shall have the right at its own cost and expense to file, prosecute, and maintain the Licensed Patents in the Territory.  This includes prosecuting to issuance, paying the issue fees for and maintaining valid and enforceable issued Patents in the name of SDI for each of the patent applications listed in Schedule 1.  (To facilitate this, SDI shall provide to Avigen within[*]after the Commencement Date, a complete copy of the file history and correspondence for each Listed Patent Right.  Also, SDI shall inform Avigen within[*]business days after the Commencement Date of any impending deadlines (such as office action responses falling due) within the first[*]after the Commencement Date.  SDI shall also promptly provide to Avigen any letter of authorization or similar documents required for Avigen to assume prosecution of the Licensed Patents in the Territory.)

Avigen shall consult in good faith with SDI with respect to Avigens prosecution of the Licensed Patents.  To that end, Avigen shall provide SDI with a copy of all correspondence (including office actions) received from patent offices within[*]business days after receipt by Avigen itself (which may be later than when its external counsel receives such correspondence).  Avigen shall provide SDI with a draft of any filing or correspondence with a patent office that Avigen proposes to make, no later than[*]days prior to when Avigen proposes to file or send such filing or correspondence.  Avigen shall reasonably incorporate SDIs comments raised in consultation, to the extent SDIs comments are consistent with the goal of securing the broadest patent monopoly reasonably available
that remains valid taking into account the prior art.



Avigen shall not finally abandon any Licensed Patent (or claim or portion of a Licensed Patent), without first offering to SDI, no later than[*]days prior to any such proposed abandonment,  the right to prosecute and maintain such Licensed Patent (or claim or portion of a Licensed Patent) at SDIs own expense.

8.3        Improvements.



|8.3.1 | Disclosure and Ownership.  All patentable[*]made or generated by either Party or its Affiliate in the course of performing hereunder or exercising a right granted hereunder (or, in SDIs case, performing Tolperisone-related activities for outside the Territory) and whether or not having broader applicability than with Tolperisone Products (each, an Improvement and all Patent rights therein, an Improvement Patent) shall be promptly disclosed by the inventing Party to the other Party in reasonable detail.  All such Improvements (and the Improvement Patents claiming them) solely invented by either Party (or solely by its employees or other humans who are its agents) shall be and remain the sole property of the solely inventing Party.  All such Improvements (and
the Improvement Patents claiming them) jointly invented by the Parties (or jointly invented by at least one employee or other human who is the agent of one Party, and at least one employee or other human who is the agent of the other Party) (these Improvement Patents are Joint Improvement Patents) shall be jointly owned by the Parties, subject to the licenses (a) to Avigen in Section 2.1, Section 10.4.2 (in case of a termination covered by such Section) and in the Supply Terms and (b) to SDI in Section 8.3.2.  The right of the Parties as joint owners outside the scope of such licenses shall be as per Section 8.3.4.

Inventorship shall be determined in accordance with[*]patent law.



|8.3.2 | Rights and Licenses under Improvements and Improvement Patents.  The Improvement Patents to the extent owned by SDI (including SDIs interest in the Joint Improvement Patents) are included among the Licensed Patents exclusively licensed to Avigen in Section 2.1, Section 4.5.5, Section 10.4.2 (in case of a termination covered by such Section) and in the Supply Terms.  Avigen hereby grants to SDI[*]exclusive license under Avigens interest in the Improvements Patents (including Avigens interest in the Joint Improvement Patents) to practice such Inventions outside the Territory.  Such license granted by Avigen shall only be sublicensable to Other Licensees who grant an equivalent license back to Avigen with respect to the Territory under all Tolperisone-related (including via
claiming its composition, manufacture, formulation or use (including methods of administration)) Patents (a) claiming inventions by or on behalf of such Other Licensee, or (b) otherwise Controlled by such Other Licensee.  Such license granted by Avigen shall endure for the full term of this Agreement, and shall survive all terminations of this Agreement other than terminations for SDIs material breach.

Other than the foregoing license under Improvement Patents and the right to use Avigens Clinical Trial Information outside the Territory (set forth in Section 5.11), Avigen grants SDI and its Affiliates no licenses express or implied under any Patents or Know-How owned or controlled by Avigen.



|8.3.3 | Filing and Prosecution.  Prosecution of Improvement Patents that are Licensed Patents but are not Joint Improvement Patents is as per Section 8.2.  The Parties shall mutually agree which Party shall file, prosecute and maintain the Joint Improvement Patents;providedthat if they are unable to agree,[*]The Parties shall cooperate with respect to the filing, prosecution and maintenance of the Joint Improvement Patents.  Avigen has the sole right to file, prosecute and maintain Improvement Patents that are solely owned by Avigen.

Each Party agrees to reasonably cooperate with the other to provide any written permissions, consents, licenses and waivers necessary to achieve these same rights in countries other than the US.



|8.4 | Infringement of the Licensed Patents
|--- | ------------------------------------



|8.4.1 | Notice.  Each Party shall inform the other Party promptly if it becomes aware of any actual infringement, or potential or threatened infringement, of any of the Licensed Patents by Tolperisone Product-related activities in the Territory.  A Party providing a notice under this Section shall disclose any evidence in its possession to support an allegation of infringement.  The Parties shall consult with each other promptly after any such notice to decide the best way to respond to such infringement.  In these discussions, the Parties may seek to agree on a joint program of action, including how the costs of any such action are to be borne and how any damages or other sums received from such action are to be distributed, however, unless the Parties execute a written amendment to this Agreement (executed by authorized officers of each Party,
as per Section 12.2), with respect to alleged actual infringement of the Licensed Patents in the Territory by activities with Tolperisone Products (Territory Infringement Territory Infringement includes, to avoid any doubt, any acts that would give rise to a right to bring suit against a generic under Hatch-Waxman (as it may be amended or under any legislation that may replace or supersede it)), the remainder of this Section 8.4 shall apply.

|8.4.4 | Cooperation.  Each Party shall reasonably cooperate with the other Party in any suit brought by that other Party under Section 8.4.2 or 8.4.3.  To support the costs of this cooperation, the Party bringing suit shall reimburse the cooperating Party for all reasonable out-of-pocket, external costs and expenses incurred by the cooperating Party in providing such cooperation.  This excludes, however, the cooperating Partys costs of retaining independent counsel, if the cooperating Party chooses to do so.  The cooperating Party is entitled to invoice the Party bringing suit for such costs and expenses as frequently as monthly; the cooperating Party shall provide documentation for the invoice if requested in writing by the Party bringing suit;  and these invoices shall be payable (and the Party bringing suit shall pay them) within thirty
(30) days after receipt of the invoice by the Party bringing suit.

SDI shall ensure that its proposals with respect thereto are on the advice of appropriately experienced patent counsel, and Avigen shall take all due account of such proposals in consultation with SDI.  If (a) for any reason the Parties do not agree on the strategy for defense of such suit as regards issues of validity and enforceability of Licensed Patents, and (b) Avigens proposal to conduct such defense involves any admission of invalidity or unenforceability of the Licensed Patent (or claim or portion of a Licensed Patent), then (c) Avigen shall not make any admission of invalidity or unenforceability, without first[*]If[*]to[*]such[*]as to[*]and[*]then[*]shall[*]of[*]including[*]directed at achieving a[*]in the[*]on the one hand, and[*]on the other hand.

|8.5.1 | Intention.  The Parties agree that they wish any issued patent within the Licensed Patents that claims the Licensed Products composition, manufacture or use in a way that legally qualifies for listing in the Orange Book for the Licensed Products (Relevant Patents) to be listed in the Orange Book with respect to the Licensed Products in accordance with the Federal Food, Drug, and Cosmetic Act, as amended by the Hatch-Waxman Act and any subsequent amendments.  The Parties shall commence discussions to seek to agree, at NDA filing for a particular Licensed Product, and shall agree no later than[*]thereafter (or within such time period commence the procedures of Section 8.5.3 to determine whether particular Licensed Patents are Relevant Patents), which of the Licensed Patents
meet the standard for Relevant Patents, that will therefore be notified to the FDA for listing in the Orange Book.  Avigen shall be responsible for providing the FDA with the required patent information regarding the Relevant Patents, and for using all Diligent and Reasonable Efforts to seek to procure that the Relevant Patent(s) is/are listed in the Orange Book, whether such Relevant Patents issue prior to, on the date of or subsequent to NDA Approval.

|8.5.2 | Timing to List.  Avigen shall provide the FDA with such patent information as soon as practicable, but in any event no later than[*]prior to the deadline for listing.  Avigen shall notify SDI contemporaneously upon submitting such patent information to the FDA.  Should Avigen fail to notify SDI of submission of such patent information within such period, then[*]and[*]with respect to[*]or that have been determined[*]to be[*]the patent information regarding that Relevant Patent to the FDA[*](other than

|8.5.3 | Procedure to Determine Relevant Patents.  For Licensed Patents that are issued as of NDA filing for a particular Licensed Product, if the Parties do not agree in writing whether particular such Licensed Patents are Relevant Patents within[*]after such NDA filing, then within an additional[*]then SDI may refer the matter for dispute resolution.  The dispute resolution shall be as per the procedure of Section 8.9.1.2 appliedmutatis mutandisto determine on a Licensed Patent-by-Licensed Patent basis which of them are Relevant Patents.  For Licensed Patents that are not issued as of NDA filing but later issue, the Parties shall commence their discussions as to whether such Licensed Patent is a
Relevant Patent promptly after the notice of allowance for such Licensed Patent is received by Avigen, shall complete such discussions within[*]and shall commence the determination procedure under this Section 8.5.3 (if any) within[*]thereafter.

|8.6 | Patent Term Extension.  The Parties shall discuss any extension of patent term that may be available for any Licensed Patent with respect to each Licensed Product.  After consulting with SDI, if Avigen chooses to do so it shall be entitled to apply to extend the term of any Licensed Patent with respect to Licensed Product(s) in any one or more countries of the Territory.  If at the time the last Valid Claim of a Licensed Patent supporting a Royalty Term hereunder is scheduled to expire it is the case that in the US only one Patent may be extended with respect to each Licensed Product, and each Patent may only be extended once, Avigen shall make its decision whether to extend the term of a Licensed Patent with respect to a particular Licensed

|8.7.2 | The Party against which such Third-Party infringement is brought is entitled to defend itself against the suit and to control such defense, and will bear the full costs of such defense (but to the extent any resulting damages are required to be indemnified for under Article 9, this indemnification shall remain available).  Nothing in this Section 8.7 is intended to alter the provisions of Article 9 regarding Indemnification.  Avigen is entitled to tender defense of any Third-Party infringement suit to SDI to the full extent SDI is required to Indemnify for such suit under Article 9.  In addition, to the extent any such suit that Avigen is entitled to tender relates to an injunction rather than money damages, Avigen is entitled to defend and control at its expense the portion of the suit that relates to the injunction, while still tendering defense of the
remainder of the suit.

If such two (2)
people cannot agree on the third person, then the arbitral body referred to in Section 12.9.2 shall select the Patent Expert who shall be the attorney to resolve the dispute.)  The Parties shall share equally the expenses incurred for the services of such Patent Expert and arbitral body.

|--- | -------------------------



The Licensed Products shall be delivered by SDI to AvigenFCA(in accordance with Incoterms 2000 Edition) Avigens receiving facility stated in Avigens Purchase Order for each shipment (and except as to details explicitly contradicted in this Section 5.2; the FCA term as so modified, Contract FCA).  The right and title to (and risk of loss of) the quantities of Licensed Products supplied hereunder shall pass to Avigen upon delivery Contract FCA to Avigens receiving facility stated in Avigens purchase order for each shipment.



|5.3 | Vendor Lot Numbers.  Seller shall number each shipment with a vendor lot number that allows the Parties to trace raw materials and/or components used to manufacture such shipment of Licensed Product.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5.4 | Acceptance and Rejection.
|--- | -------------------------



|5.4.1 | Notice;  Agreement.  Any rejection of a shipment for non-conformity in quality and/or quantity shall be made in writing no later than[*]days from the date of delivery of each shipment of Licensed Product.  If Avigen makes no such claim within such[*]day period, Avigen shall be deemed to have accepted such shipment of Licensed Product.  If Avigen does make such a claim within such[*]day period, SDI shall accept or reject such claim by written notice to Avigen within[*]working days after Avigens rejection notice.  If SDI accepts Avigens rejection or the Parties reach written agreement for SDI to accept the rejection, the failure shall
be deemed remedied by replacement with the same Licensed Product conforming with the Specifications at no additional cost for Avigen as promptly as physically and technically possible, with SDI bearing all shipping and insurance costs, in any event no later than[*]after such acceptance or settlement.

|5.4.2 | Third-Party Testing.  If any such disagreement is not resolved (as evidenced by a written agreement) by the Parties within[*]working days after SDI notifies Avigen in writing that SDI rejects Avigens rejection of the shipment, then the question whether the shipped quantities conformed to the applicable Specifications upon delivery will be determined by the test result of a mutually acceptable independent laboratory.  The laboratorys decision shall be final and binding upon the Parties.  (If the Parties cannot agree on the laboratory within[*]business days, then Avigen is entitled to choose any laboratory that is a Third Party.)  The expenses of the Third-Party laboratory testing will be borne by the losing Party.

|5.4.3 | Tolling of Obligations.  If any such claim as is referred to above is resolved in Avigen's favor and if as a result of SDI supplying such non-conforming Licensed Product Avigen is unable to fulfill its obligations under of any of the terms of this Agreement (including the License Agreement) Avigen shall be relieved of its obligations to the extent required to prevent it being in breach until the situation is remedied.  Avigen shall have the benefit of such relief on a temporary basis where any such claim is in dispute and is not resolved. If any such claim is resolved in SDI's favor any such relief shall immediately be withdrawn, and if notified in writing under Section 10.2.3 of any material breach, Avigen shall have the cure period set forth in such Section in which to cure the breach.  For clarity, this Supply Terms Section 5.4.3
shall not be read to limit any other remedies available to Avigen under this Agreement, at law or in equity.
|----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|5.4.4 | Reasons for Rejection.  Avigen is entitled to reject a shipment of Licensed Product for any of the following reasons:  (a) quantities of Licensed Product therein did not conform to specifications; (b) quantities of Licensed Product therein were not manufactured in accordance with cGMP or other applicable Regulatory Requirements; (c) quantities of Licensed Product therein are adulterated or misbranded within the meaning of the United States Federal Food, Drug and Cosmetic Act; and/or (d) quantities of Licensed Product therein are not packaged and shipped in accordance with the requirements of these Supply Terms.

|6.1.2 | CR-Qualified Product.  The quantity necessary to satisfy the next (at the time)[*]of Avigens requirements for CR-Qualified Product based upon Avigens forecasts and orders placed in accordance with Supply Terms Section 2.3.
|----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Half of each foregoing safety stock shall be held as raw API and the rest as Finished Product.Avigens requirements as used throughout these Supply Terms includes Avigen requirements for itself, as well as Avigens requirements for its Affiliates, Sublicensees and Distributors.



After Launch of each Licensed Product, Avigen also[*]to maintain an inventory (including amounts held by Avigen directly and all inventory in trade channels within the Territory) of up to[*]of its projected requirements of each the IR Product and the CR-Qualified Product.  However, Avigen is not required to hold this level of inventory.



|6.2 | Supply Shortage.  If there is a shortage of any Licensed Product, then without limiting Avigens entitlement to have its orders under Supply Terms Section 2.3 filled to the full extent they do not exceed[*]of the applicable forecast under such Supply Terms Section, Avigen shall be entitled to be supplied with at least a proportionate share of the available quantities of Licensed Products.  Such proportionate share shall be calculated based on (a) Avigens historical orders relative to the total of Avigens, SDIs and SDIs Other Licensees orders (or usage) in the year leading up to the shortage, or (b) if Avigen had not yet Commercially Launched the affected Licensed Product at least[*]prior to the shortage,
the US market size, relative to the size of the market in the countries where SDI and its Other Licensees have Regulatory Approval for such Licensed Product.

|6.3 | Redundant Sourcing.  As provided in Supply Terms Section 3.5, by[*]after the Commencement Date for the IR Product, and[*]from Initiation of the Pivotal Trial Program for the CR-Qualified Product, SDI shall have established and validated two (2) facilities (one of which for each Licensed Product must be within the Territory) from which quantities of such Licensed Product in Finished Product form may be legally sold by Avigen in the US in accordance with Avigens NDA for such Licensed Product.  If SDI fails to do so by such time (as the same may be extended in accordance with Section 3.5), then Avigen shall notify SDI.  SDI shall have a period of an additional[*]to complete establishment of
such two (2) facilities (one of which must be within the Territory).  If SDI fails to establish and validate the second source by the end of such additional[*]period, or ceases thereafter to maintain supply of such Licensed Product in Finished Product form from at least two (2) different, physically separated facilities (one of which must be within the Territory), then a Second Source Failure shall have occurred with respect to such Licensed Product.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



If a Second Source Failure occurs with respect to any Licensed Product, then Avigen will benefit from the license provided in Supply Terms Section 6.5.1, and be entitled (but not obliged) to supply[*]of such Licensed Product each year by itself manufacturing or engaging an Affiliate or a Third Party to manufacture such Licensed Product, in addition to any amounts that are not automatically Binding Amounts and that SDI does not accept to include in the Binding Amount for any Avigen purchase order under Supply Terms Section 2.3.4.  If requested by Avigen, SDI shall in this case provide technology transfer to Avigen (or its designee) as provided in Supply Terms Section 6.6, as regards the processes for making and testing the Finished Product form of the API for such Licensed Product.  SDI is required to continue to supply in accordance with
the other provisions of the Supply Terms Avigens full requirements of such Licensed Product, until Avigens other source is established and validated.  SDI shall supply Avigens purchase orders under Supply Terms

will be for less than Avigens entire requirements (but no less than[*]of such Licensed Product).  SDIs obligation to supply and Avigens obligation to purchase other Licensed Products is unaffected by the Second Source Failure for a particular Licensed Product.



SDI shall supply Avigen with Avigens requirements of API for the Licensed Product with respect to which any Second Source Failure occurs.  This supply shall be at a price equal to SDIs Fully Burdened Manufacturing Cost of such API, on forecasting and ordering procedures that are as per Supply Terms Sections 2.3.3 - 2.3.5, appliedmutatis mutandisto API supply.  Further, if the analogous event to a Significant Supply Failure occurs with regard to API supply, Avigen shall have the right to manufacture its requirements of the API itself.



To be clear, Avigen is under no obligation to establish its own alternative supplier (whether itself or an Affiliate or Third Party) after any Second Source Failure.  Also to be clear, because there may be one or more Second Source Failures, this Section 6.3 applies to each and every Second Source Failure.



|6.4 | Significant Supply Failure.  If a Significant Supply Failure occurs, then Avigen shall notify SDI of the Significant Supply Failure.  If desired by either Party, the Committee shall meet to discuss the situation within[*]days after Avigens notice.  At this meeting, the Parties shall discuss any steps that SDI would take to ensure that its failure to supply would not be repeated.  These discussions and any of the possibilities discussed at them in no way alter Avigens rights to choose to establish its own alternative sources of supply (whether through itself, or through Affiliates or Third Parties).
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



If a Significant Supply Failure occurs, then Avigen will benefit from the license of Supply Terms Section 6.5.2.  Avigen, in its sole discretion, may choose to continue to receive from SDI under these Supply Terms all or any portion of its requirements of one or more Licensed Products from SDI after a Significant Supply Failure, and may choose to manufacture (or procure from an Affiliate or Third Party manufacture of) all or any portion of its requirements of one or more Licensed Products.  If requested by Avigen, SDI shall provide technology transfer to Avigen (or its designee) under Supply Terms Section 6.6 with respect to any and all Licensed Products (and any and all APIs for which there is a supply failure under the next paragraph).



If and to the extent requested by Avigen, SDI shall supply Avigen with Avigens requirements of API for any Licensed Product Avigen chooses to manufacture any quantities of after a Significant Supply Failure.  This supply shall be at a price equal to SDIs Fully Burdened Manufacturing Cost of such API, on forecasting and ordering procedures that are as per Supply Terms Sections 2.3.3 - 2.3.5, appliedmutatis mutandisto API supply.  Further, if the analogous event to a Significant Supply Failure occurs with regard to API supply, Avigen shall have the right to manufacture its requirements of the API itself.



To be clear, Avigen is under no obligation to establish its own alternative supplier (whether itself or an Affiliate or Third Party) for any Licensed Product or multiple Licensed Products after a Significant Supply Failure.  Also to be clear, because there may be one or more Significant Supply Failures, this Section 6.4 applies to each and every Significant Supply Failure.
