2.1

Purchases During Transition Period.

(a) Purchase. During the Transition Period, ViroPharma will purchase and Lilly will sell to ViroPharma the Inventory for distribution and sale in Territory at the times and in the amounts set forth in the Transition Services Agreement. Lilly represents and warrants that Schedule 2.1 (which shall be delivered within 3 days following the Closing Date) is a complete and accurate list and description of the Inventory as of the Closing Date by lot (including a denotation of whether it is a full or partial lot) and expiration date.

(b) Inventory. [***], ViroPharma will purchase and Lilly will sell to ViroPharma all remaining amounts of Inventory not previously sold to ViroPharma pursuant to subparagraph (a) above. At the time of such purchase and sale, Lilly will provide to ViroPharma, an updated Schedule 2.1 and a certificate, executed by a duly authorized representative of Lilly, certifying that such updated Schedule 2.1 is a complete and accurate list and description of the Inventory

-5-

(c) Use of Inventory. The quantity of Marketed Product comprising the Inventory and any inventory purchased during the term of the Transition Services Agreement will be applied towards ViroPharma’s minimum purchase requirements as set forth in Sections 4.1 and 4.4, below, and Lilly’s maximum supply obligations set forth in Sections 4.2, 4.4 and 4.5. Lilly will have no obligation to re-label or over-label the Inventory. ViroPharma will not re-label or over-label any Inventory. ViroPharma shall purchase the Inventory at the Purchase Price as defined in Section 2.2 below. Payment shall be made in accordance with Section 2.4. For quantities purchased during the Transition Period, payment shall be made in accordance with the Transition Services Agreement. At any time within 30 days following the end of the term of the Transition Services Agreement, representatives of ViroPharma shall have the right to physically inspect the Inventory purchased pursuant to subparagraph (b) above. To the extent that a variance exists between the quantity or quality of Marketed Product purported to be sold to ViroPharma and the actual quantity and/or quality shown by the inspection, the Parties agree to reconcile the difference within Thirty (30) days of ViroPharma providing notice to Lilly of such variance. The Parties shall mutually agree upon the procedures to be followed in any such inspection. Lilly acknowledges and agrees that ViroPharma is under no obligation to purchase from Lilly any Inventory that is not useable and saleable in the ordinary course or that does not otherwise meet the Specifications and other representations and warranties set forth in this Manufacturing Agreement.

2.2

Purchase of Marketed Product Following Transition Period. As of the end of the Transition Period and during the Contract Period, subject to the terms of this Manufacturing Agreement, Lilly will manufacture and supply Marketed Product (in addition to the Inventory) for and to ViroPharma during

-6-

the Contract Period and ViroPharma will, during the Contract Period, purchase from Lilly Marketed Product for resale in the Territory. During the Contract Period, ViroPharma will pay the purchase prices for Marketed Product set forth on Schedule 2.2 attached hereto (the “Purchase Prices”). The expiration date with respect to all Marketed Product purchased by ViroPharma pursuant to this Section 2.2 will be no earlier than [***] from the date of shipment from Lilly to ViroPharma. The Purchase Prices exclude all applicable freight and insurance expenses in order for the Product to be shipped to ViroPharma in compliance with Section 4.7. On [***] the Purchase Prices shall automatically increase to the Purchase Prices set forth on Schedule 2.2 and shall be in effect until [***]. Any increase in Purchase Price after [***] will be determined in accordance with the procedure set forth in Section 8.8. Lilly will have no obligation to manufacture or package Marketed Product for ViroPharma in any presentation not set forth in Schedule 2.2. Schedule 2.2 lists Lilly’s and its Affiliates’ site where Marketed Product will be manufactured. Lilly shall not change the manufacturing site which supplies Marketed Product without the prior written consent of ViroPharma which consent shall not be unreasonably withheld.

2.3

Supply Chain.

(a) ViroPharma acknowledges that Lilly has executed and delivered to the parties thereto the Lilly Third Person Supply Chain Agreements. Lilly has provided ViroPharma with complete and accurate executed copies of the Lilly Third Person Supply Chain Agreements. Lilly shall use commercially reasonable efforts to assist ViroPharma in entering into agreements with the Third Party Suppliers on substantially similar terms, to those included in the Lilly Third Person Supply Chain Agreements for Marketed Product in the Territory (“ViroPharma Third Person Supply Chain Agreements”). In the event that ViroPharma is not able to enter into such agreements with the Third Party Suppliers on terms satisfactory to ViroPharma, Lilly shall assign the appropriate

-7-

Lilly Third Person Supply Chain Agreements pursuant to the terms of a Cooperation Agreement between Lilly and ViroPharma attached hereto as Exhibit A. The effective date of purchases by ViroPharma under of the ViroPharma Third Person Supply Chain Agreements or assignment of the Lilly Third Person Supply Chain Agreements, if necessary, will be at Lilly’s discretion upon reasonable notice to ViroPharma but will occur no earlier than after the Third Person Supply Chain has all necessary Regulatory Approvals for the manufacture and supply of Marketed Product and shall be subject to Section 8.3(c). Section 8.8 of this Manufacturing Agreement provides for an emergency supply of Marketed Product in the event that there is a delay in ViroPharma being able to obtain Marketed Product pursuant to the Third Person Supply Chain. If the provisions of that Section 8.8 are invoked to extend Lilly’s supply obligation under this Manufacturing Agreement, the effective date of purchases by ViroPharma under Third Person Supply Chain or the assignment of the Third Person Supply Chain agreements, if necessary, will be after Lilly has fulfilled its supply obligations and the Third Person Supply Chain has obtained Regulatory Approval. Notwithstanding the foregoing, nothing in this Section is intended to extend the Contract Period if Regulatory Approval is not obtained.

(b) During the Contract Period, Lilly will use commercially reasonable efforts to establish the Third Person Supply Chain pursuant to the Lilly Third Person Supply Chain Agreements. Lilly will keep ViroPharma advised of all significant actions, including, without limitation, any deviation from the Project Agreement, in connection with the establishment of the Third Person Supply Chain, and will share information, consult with ViroPharma and include ViroPharma in all discussions in connection with any material decisions, including those regarding the development program; provided that Lilly shall not amend the Lilly Third Person Supply Chain Agreements without the prior written consent of ViroPharma, and that ViroPharma’s consent to any such amendment shall not be a defense to a claim of breach of representation and warranty by Lilly. Lilly has entered into a Project Agreement with one of the Third Person

-8-

Suppliers pursuant to the Master Agreement, as amended, between Lilly and such Third Person Supplier for the manufacture and supply of Marketed Product as described in the Project Agreement (“Project Agreement”). With respect to the Project Agreement, Lilly will be responsible for the Development Activity Costs and any Capital Reimbursement costs (as described in the Price Exhibit to the Project Agreement) that are due and owing prior to or as of the date that the Third Person Supply Chain receives Regulatory Approval (“Regulatory Approval Date”). Following such Regulatory Approval Date, ViroPharma will be responsible for all Development Activity Costs, Stability Costs and any Capital Reimbursement costs incurred (as described in the Price Exhibit to the Project Agreement). If payment for such costs incurred following the Regulatory Approval Date is due to such Third Party Supplier prior to assignment, Lilly will make such payment on behalf of ViroPharma, will invoice ViroPharma for the amount of such payment and provide to ViroPharma a copy of the invoice from such Third Party Supplier for such amount.

2.4

Terms of Payment. ViroPharma agrees to pay all invoices within [***] from the date of the applicable invoice, provided that all invoices are dated no earlier than the date of shipment of the applicable Marketed Product. ViroPharma shall make all payments to Lilly by Federal Reserve wire transfer to an account previously designated by Lilly in writing. All payments made under this Manufacturing Agreement will be made in United States currency. Any payments not made when due shall be subject to interest as provided in Section 2.4 of the Assignment Agreement.

2.5

Extension of Credit. ViroPharma acknowledges that Lilly will establish a credit line for ViroPharma to facilitate its purchases of the Marketed Product on the Forty[***] payment terms set forth in Section 2.4 and that Lilly may periodically review and adjust this credit line as it deems appropriate. In consideration for providing this credit line, ViroPharma agrees to provide Lilly, upon reasonable request, the financial information reasonably necessary for Lilly

-9-

to perform credit reviews; provided, however, that if ViroPharma does not provide such information, or if Lilly’s analysis of that information does not meet Lilly’s standard credit approval guidelines, then Lilly will have the right to ask for cash in advance of shipment. Lilly also reserves the right to ask for cash in advance of shipment should ViroPharma experience a condition of insolvency, or if notice of intent to terminate has been issued pursuant to Section 8.2 of this Manufacturing Agreement. Lilly agrees and acknowledges that ViroPharma currently meets Lilly’s standard approval guidelines for a line of credit assuming purchases of the Purchase Maximums pursuant to the terms of this Manufacturing Agreement and Lilly has no current intention of asking ViroPharma for cash in advance of shipment and has no reason to believe that it will do so in the future.

2.6

Transition Services Agreement. Simultaneously herewith, the Parties shall execute and deliver the Transition Services Agreement pursuant to which, among other things, Lilly will provide warehousing, distribution and other transition services to ViroPharma, including sales and accounts receivable functions. During the term of the Transition Services Agreement, to the extent that any provision of this Manufacturing Agreement conflicts with the Transition Services Agreement, the Transition Services Agreement shall apply.

2.7

Equipment. Subject to the terms and conditions set forth herein and in the ▇▇▇▇ of sale, a form of which is attached hereto as Exhibit B (“▇▇▇▇ of Sale”), within [***] after the effective date of purchases by ViroPharma under Third Person Supply Chain Agreements or the assignment of the Third Person Supply Chain Agreements, Lilly shall, and shall cause its Affiliates to, assign, sell, convey, transfer and deliver to ViroPharma, and ViroPharma shall acquire, buy and accept from Lilly and its Affiliates, all of Lilly’s and its Affiliates’ right, title and interest in, to and under the Equipment, free and clear from all Encumbrances other than Permitted Encumbrances. Except as otherwise set forth herein, the Equipment is sold to ViroPharma “AS IS.” In

-10-

connection with ViroPharma’s purchase of the Equipment, Lilly shall execute and deliver a Bailee’s Subordination substantially in the form attached hereto as Exhibit C. During the period of time from the Closing Date until the date the Equipment is received by ViroPharma, Lilly shall maintain and insure the Equipment in the ordinary course. Lilly will notify ViroPharma when the Equipment is available and ViroPharma will make all arrangements for removal and shipment of the Equipment to ViroPharma at ViroPharma’s cost. If the Equipment is not removed from Lilly’s premises within [***] of the date that Lilly notifies ViroPharma that the Equipment is ready for removal, upon reasonable notice to ViroPharma, Lilly may dispose of the Equipment at Lilly’s discretion without obligation to ViroPharma.

ARTICLE 3

MANUFACTURING AND QUALITY

3.1

Manufacturing. Lilly will manufacture, package, label, test, prepare for shipment and ship Marketed Product to ViroPharma from Lilly’s facilities, or the facilities of a Third Person under subcontract with Lilly, at the times and in the quantities set forth by ViroPharma in a purchase order pursuant to Section 4.5, subject, however, to the quantity restrictions set forth in Sections 4.1, 4.2 and 4.4. Each shipment of Marketed Product: (i) will have been manufactured in accordance with cGMP in effect at the time of manufacture, (ii) will not be adulterated or misbranded by Lilly within the meaning of the FDCA, (iii) will not have been manufactured, sold or shipped in violation of any Applicable Laws in any material respect, and (iv) upon delivery to ViroPharma, ex works, Lilly’s loading dock will convey good title to such Marketed Product to ViroPharma and such conveyance will be free and clear of any Encumbrance other than any Encumbrances created by ViroPharma. Lilly acknowledges and agrees that ViroPharma is under no obligation to purchase from Lilly any Marketed Product that does not meet the specifications and the representations and warranties set forth in this Manufacturing Agreement. Lilly will fax (i) a certificate of analysis

-11-

and/or a certificate of compliance confirming that such Marketed Product meets the Specifications then in effect, (ii) Lilly’s standard release documents and (iii) any other appropriate documentation, to be mutually agreed upon by the Parties, to ViroPharma no later than [***] after shipment of Marketed Product to ViroPharma.

3.2

Modifications.

(a) Proposed Modification. ViroPharma will inform Lilly in writing as soon as reasonably practical of any proposed modification to the (i) Specifications, or (ii) analytical requirements of the Marketed Product (“Modification”). For the purpose of this Section 3.2, the term Modification shall not include any proposed change to the Specifications that relates solely to the identification of the Parties, their respective tradenames and trademarks or Third Person manufacturers, packers or distributors on the Current Labeling or the New Labeling (as such terms are defined in Article 5); such changes shall be governed solely by Article 5. Lilly will cooperate with the implementation of such Modification by, among other things, informing ViroPharma in writing of the amount of any additional costs and expenses (including capital expenditures, regulatory and any other costs) Lilly would actually incur due to the Modification. If ViroPharma elects to adopt the Modification, ViroPharma will promptly reimburse Lilly for any required capital expenditures, regulatory and other costs associated with the Modification and the Purchase Price will be increased to reflect any increase in on-going Marketed Product manufacturing costs resulting from such Modification (exclusive of any indirect costs associated with capital expenditures actually paid for by ViroPharma), all as are agreed in writing by both Lilly and ViroPharma. Any assets acquired by Lilly on ViroPharma’s behalf pursuant to this Section 3.2 and paid for by ViroPharma will be owned by ViroPharma, maintained by Lilly in the normal course of business and, to the extent severable from Lilly’s facility without unreasonable damage or unreasonable disruption to such facility, returned to ViroPharma as soon as practicable after the termination or expiration of this Manufacturing Agreement.

-12-

ViroPharma will also promptly pay for any additional analytical tests or any other additional requirements resulting from such Modifications. Lilly shall work with ViroPharma to ensure that any Modification shall become part of the Third Person Supply Chain. If ViroPharma is unwilling to pay Lilly’s costs to implement such Modification or the increase in Purchase Price associated therewith, then ViroPharma will withdraw the proposed modification and the Specifications, analytical requirements or other matters proposed to be modified, as applicable, will remain in full force and effect.

(b) Restrictions. Lilly will follow the above-described procedure, including the payment of any capital expenditures, regulatory and other costs, if it proposes a Modification. Lilly will not implement any Modification (other than with respect to minor changes to secondary packaging not otherwise prohibited under Section 5.1) without ViroPharma’s prior written consent, which consent will not be unreasonably withheld. Either party will notify the other as soon as practical after becoming aware of any Modifications that are required by Applicable Law and that could have an impact on such party’s performance of this Manufacturing Agreement. Any Modifications that are required by Applicable Law will be deemed (and treated as) Modifications proposed by ViroPharma under this Section 3.2; provided, however, that if ViroPharma is not willing to pay for such Modification that is required by Applicable Laws as described in this Section 3.2 ViroPharma may terminate this Manufacturing Agreement as of the earlier of (i) the date Applicable Laws require the implementation of such Modification that is required by Applicable Laws, or (ii) thirty (30) days after written notice from ViroPharma to Lilly. Every proposed Modification will be treated separately.

(c) Additional Rights and Obligations. Lilly shall be obligated to make any and all Modifications which are required by Applicable Laws and shall use commercially reasonable efforts to make all other Modifications proposed under this Article 3. ViroPharma shall be responsible for the costs of such

-13-

Modifications. In no event will Lilly be required to make (or not to make) a Modification that is prohibited (or required) by applicable regulations or regulatory authorities. ViroPharma will have sole responsibility for obtaining any and all necessary regulatory approvals from the FDA for Modifications and for reporting any Modifications to the FDA as appropriate.

(d) Proposed Modifications. Except as set forth on Schedule 3.2(d), Lilly represents and warrants to ViroPharma that Lilly is not currently executing nor does Lilly have any reason to execute or consider, any Modification that would require the approval of or a filing with the FDA, including any change in Applicable Law. Lilly shall indemnify ViroPharma for any costs and expenses (including capital expenditures, regulatory and other costs) incurred due to any such Modification Lilly knew of or had reason to know about on the Closing Date.

3.3

Quality Control and Assurance; cGMP Audit.

(a) Quality Control and Assurance. Lilly will manufacture the Marketed Product in compliance with the Specifications. Lilly will perform quality control and quality assurance testing on the Marketed Product to be delivered to ViroPharma hereunder in accordance with the Specifications, cGMP and the MRD/Quality Agreement.

(b) Access to Lilly Facilities by ViroPharma Representatives. Upon no less than Thirty (30) days’ written notice to Lilly and no more than one time during each Calendar Year in the Contract Period, Lilly will permit ViroPharma to conduct an Audit of Lilly’s facilities during regular business hours for the purpose of making quality control inspections to assure cGMP compliance of the facilities used in the manufacturing, receiving, sampling, analyzing, storing, handling, packaging and shipping of Marketed Product, including, but not limited to, in the receipt, storage and issuance of raw materials, labeling and packaging components, and ingredients thereof. Notwithstanding the immediately

-14-

preceding sentence, in the event of either (i) a rejection of Marketed Product by ViroPharma pursuant to Section 5.3, because of a failure to meet Specifications, (ii) a change in Manufacturing Site pursuant to 2.2(a), or (iii) a negative regulatory inspection that could impact Marketed Product quantity or supply of Marketed Product to ViroPharma, then ViroPharma will have the right to conduct additional Audits under the provisions of this Section 3.3 during the same Audit Period. In addition, Lilly shall notify ViroPharma immediately after a negative regulatory inspection that could affect the quality of the Marketed Product or supply of the Marketed Product to ViroPharma. Any ViroPharma representatives will be advised of the confidentiality obligations of Article 9, below, and will follow such security and facility access procedures as are reasonably designated by Lilly.

Lilly may require that at all times the ViroPharma representatives be accompanied by a Lilly representative and that the ViroPharma representatives not enter areas of the facility used in production of the Marketed Product at times other than when the production of Marketed Product is occurring to assure protection of Lilly or Third Person confidential information. Lilly will provide ViroPharma with a written response to any written Audit observations provided by ViroPharma as soon as reasonably practicable but in no event later than sixty (60) days of Lilly’s receipt thereof.

(c) Safety Procedures. Lilly will have responsibility for developing, adopting and enforcing safety procedures for the handling and production of Marketed Product by Lilly and the handling and disposal of all waste relating thereto. Such responsibilities will terminate as to Marketed Product upon delivery thereof to ViroPharma’s common carrier.

(d) Access to ViroPharma Facilities by Lilly Representatives. Upon no less than Thirty (30) days’ written notice to ViroPharma and no more than one time in a Calendar year during the Contract Period, ViroPharma will permit Lilly to conduct an Audit of the specific ViroPharma facilities used in the receiving,

-15-

sampling, analyzing, storing, handling, packaging and shipping of Marketed Product during regular business hours for the purpose of making quality control inspections to assure cGMP compliance. Notwithstanding the immediately preceding sentence, in the event of a rejection of Marketed Product by ViroPharma pursuant to Section 5.3 below, because of a failure to meet Specifications, then Lilly will have an additional right to conduct an Audit under the provisions of this Section 3.3. Any Lilly representatives will be advised of the confidentiality obligations of Article 9, below, and will follow such security and facility access procedures as are reasonably designed by ViroPharma. ViroPharma may require that at all times the Lilly representatives be accompanied by an ViroPharma representative and that the Lilly representatives not enter areas of the facility unrelated to the Marketed Product. ViroPharma will provide Lilly with a written response to any written Audit observations provided by Lilly within sixty (60) days of ViroPharma’ receipt thereof; provided, however, that ViroPharma will have no obligation to further act upon such Audit, but will consider the Audit in good faith. Lilly acknowledges that the receiving, sampling, analyzing, storing, handling, packaging and shipping of the Marketed Product will occur at the facilities of a third party designated by ViroPharma, at its sole discretion. ViroPharma shall use commercially reasonable efforts to enter into an agreement with such third party which would provide access to Lilly on terms similar to those described in this Section 3.3(d). ViroPharma will have no further obligations to provide access other than what is agreed to with such third party and Lilly acknowledges that a third party may have additional terms, conditions and restrictions to those described in this Section 3.3(d). Such terms, conditions and restrictions shall supersede this Section 3.3(d).

3.4

Records and Accounting by Lilly. Lilly will, with respect to each lot of Marketed Product produced by it hereunder, for the longer of (i) any period required by Applicable Laws, or (ii) a period of one (1) year after the expiry of the expiration dating of such lot, keep accurate records of the manufacture and testing of the Marketed Product produced by it hereunder, including, without

-16-

limitation, all such records which are required under Applicable Laws. Access to such records will be made available by Lilly to ViroPharma during normal business hours upon ViroPharma’s reasonable written request.

ARTICLE 4

PURCHASE OF PRODUCT; FORECASTS

4.1

Minimum Purchase Requirements. Without limiting ViroPharma’s purchase obligations described in Sections 2.1 and 2.2, above, ViroPharma will purchase from Lilly, at least [***] of Marketed Product during a Contract year in the Contract Period (the “Purchase Minimum”). For purposes of this Manufacturing Agreement, the term “kilogram” when used in the context of the weight of the Marketed Product means the kilograms of [***]. ViroPharma shall be released from its Purchase Minimum obligation in the event (a) that Lilly is unable to fulfill ViroPharma’s purchase orders in the quantities or on the timeline set forth in Section 4.4, (b) of a non-monetary breach by Lilly which cannot or is not cured within 45 days pursuant to Section 8.2 or (c) of a force majeure event pursuant to Section 12.14.

For purpose of determining the date upon which Marketed Product is purchased pursuant to the terms of this Manufacturing Agreement, the date of “purchase” of Marketed Product means the date upon which Lilly or a Third Person, as applicable, is obligated to deliver such Marketed Product to ViroPharma pursuant to this Manufacturing Agreement.

4.2

Maximum Purchase Amounts. Notwithstanding Lilly’s supply obligations described in Sections 2.1, 2.2 and 4.4, Lilly will not be required to supply ViroPharma with more than [***] of Marketed Product in any Calendar

-17-

Quarter and no more than [***] of Marketed Product during a Calendar Year in the Contract Period. (the “Purchase Maximums”). For purposes of this Manufacturing Agreement, Lilly will be deemed to have “supplied” Marketed Product to ViroPharma on the date that Lilly has delivered Marketed Product to ViroPharma in accordance with Section 4.7, below.

4.3

Purchase of Product from Third Persons. Notwithstanding Section 4.2, if ViroPharma has purchased the Purchase Maximums from Lilly in a Calendar Quarter or Calendar Year, ViroPharma may, but will not be obligated to, request that Lilly provide additional quantities of Marketed Product in excess of the Purchase Maximums (“Additional Quantities”). Lilly will consider in good faith and use commercially reasonable efforts to supply Additional Quantities, including without limitation, run additional shifts, add additional personnel and work beyond normal business hours. Additional Quantities will be supplied to ViroPharma by Lilly at the current Purchase Price and the Parties will mutually agree on any additional costs. If Lilly indicates that it is unable to supply to ViroPharma such Additional Quantities or if ViroPharma does not request that Lilly produce the Additional Quantities, then ViroPharma will have the right to purchase such Additional Quantities of Marketed Product from a Third Person manufacturer, including, but not limited to, the Third Person Supply Chain; provided, however, that the purchase of Additional Quantities by ViroPharma from a Third Person manufacturer will not relieve ViroPharma of its obligation to satisfy the Purchase Minimum or purchase obligations set forth in Sections 4.1 and 4.4 from Lilly in any Contract Quarter or Contract Period, as applicable. If ViroPharma purchases any such Additional Quantities from a Third Person, ViroPharma will maintain, at its cost, all records required to identify the manufacturer of such Marketed Product.

-18-

4.4

Forecasts.

(a) Forecasts Required. Upon the Closing Date and on or before the first day of each Calendar Quarter thereafter, ViroPharma will provide to Lilly ViroPharma’s estimate of the total quantity of Marketed Product to be delivered for the following Calendar Quarter and the remaining Calendar Quarters until [***], broken down into calendar months (each a “Forecast”). The initial Forecast is attached hereto as Schedule 4.4 (the “Initial Forecast”). All future Forecasts will be in substantially the same form, but not necessarily the same amounts as the Initial Forecast. Subject to Sections 2.2 (to the extent ViroPharma’s purchase obligation pursuant to Section 2.2 is greater than the purchase obligation described in this Section 4.4(a)), 4.1 and 4.2, during each of the first [***] of the Initial Forecast or the [***] following the Closing, which ever is longer, (i) ViroPharma will be obligated to purchase [***] of the quantities of Marketed Product forecasted, and (ii) Lilly will, subject to Section 4.2, above, be obligated to supply ViroPharma with quantity ordered by ViroPharma unless the quantity exceeds [***] of the quantities of Marketed Product forecasted. Purchase of such quantities will be made during the term of the Transition Services Agreement in accordance with its terms and thereafter such purchases will be made by Purchase Orders in accordance with Section 4.5. Thereafter, subject to Sections 2.2 (to the extent ViroPharma’s purchase obligation in Section 2.2 is greater than the purchase obligation described in this Section 4.4(a)), 4.1 and 4.2, above, during each Calendar Quarter, ViroPharma will be obligated to purchase [***] of the quantities of Marketed Product forecasted for such Calendar Quarter in the Forecast in which such Calendar Quarter was the third (3^rd) Calendar Quarter of the Forecast, and Lilly will be obligated to supply ViroPharma with quantity ordered by ViroPharma unless the quantity exceeds [***] of the quantities of Marketed Product forecasted for such Calendar Quarter in the Forecast in which such Calendar Quarter was the [***] of the Forecast. Except as

-19-

otherwise specifically set forth in this Section 4.4 or elsewhere in this Manufacturing Agreement, the Parties agree that the Forecasts will be for general planning purposes only, and will not be binding on Lilly or ViroPharma.

(b) Unique and Unused Components or Materials. Reasonable quantities of unique components, or materials that are used in the manufacture of the Marketed Product, will be purchased by Lilly in reliance by Lilly on the Initial Forecast and each Forecast. If ViroPharma thereafter requests a decrease in the quantities previously forecasted for the Initial Forecast a Calendar Quarter in a Forecast in which such Calendar Quarter was the third Calendar Quarter of the Forecast that causes any obsolescence of any such unique components or materials purchased by Lilly in reliance on a Forecast, ViroPharma will be responsible to Lilly for the reasonable and direct costs and expenses actually incurred associated with said components or materials (including, but not limited to, any costs related to returning such components or material to the vendor or otherwise disposing thereof). Lilly shall keep ViroPharma reasonably advised as to the quantities of such excess unique components or materials used in the manufacture of the Marketed Product that are purchased by Lilly.

4.5

Purchase Orders.

Upon receipt and acceptance of each purchase order by Lilly hereunder, Lilly will supply the Marketed Product in such quantities (with any variances permitted hereunder) and will use commercially reasonable efforts to deliver such Marketed Product to ViroPharma on the delivery dates specified in such purchase order, unless otherwise mutually agreed to in writing by the Parties. Delivery by Lilly of greater than [***] of the quantity ordered will be accepted by ViroPharma in full satisfaction of the quantity ordered in such purchase order; provided, however, that no less than [***] of the quantity ordered is delivered by Lilly in any Calendar Quarter; provided, further, that ViroPharma will only be invoiced and required to pay for the quantities that Lilly actually delivers to ViroPharma and meets the Specifications, but the full purchase order will be applied to ViroPharma’s Purchase Minimums. Only such quantities that are actually received by ViroPharma and meet the Specifications will be applied to the Purchase Maximums.

LABELING; TRADE DRESS; NON-CONFORMING PRODUCT

5.1

Labeling, Trade Dress and Packaging.

(a) Lilly will label, prepare and pack for shipment the Marketed Product (including the Inventory) in compliance with the NDA and cGMP and in accordance with the MRD/Quality Agreement.

(b) Lilly will label and package all Marketed Product with the labels, packaging, inserts and related materials used by Lilly as of the Closing Date (the “Current Labeling”) until the New Labeling has been provided to Lilly by ViroPharma and has been implemented pursuant to Section 5.1. Lilly shall not make any material change to the Current Labeling or the New Labeling (as applicable) or the branding of the Marketed Product itself (including, without limitation, change to the use and appearance of trademarks, trade names and trade dress) without the prior written consent of ViroPharma and shall not over-label the Current Labeling or New Labeling (as applicable).

(c) After the Marketed Product NDA has been transferred to ViroPharma, ViroPharma may modify the Current Labeling to reflect, among other things, changes in usage of the respective trade names and trademarks of the Parties and any Third Person manufacturers, packers or distributors or to

-23-

otherwise create new or revised packaging, labeling, inserts or related materials for use in connection with the Marketed Products (the “New Labeling”). The Parties contemplate that ViroPharma’s name (or the name of an Affiliate of ViroPharma) will appear as the exclusive distributor of the Marketed Product and Lilly’s name will appear as the manufacturer of the Marketed Product (unless a Third Person manufactures any Marketed Product for Lilly, in which event such Third Person’s name will appear as the manufacturer of the Marketed Product). ViroPharma, at its expense, will provide Lilly with an electronic graphics file (a verified and approved “proof copy”) for any New Labeling and for any subsequent changes thereto. It is acknowledged by both Parties that ViroPharma is responsible for ensuring that the proof copy matches approved regulatory (FDA) text. Lilly shall implement any New Labeling and any subsequent changes thereto upon request by ViroPharma as soon as practicable after all applicable regulatory requirements with respect thereto have been met and in accordance with the provisions set forth in the MRD/Quality Agreement. For purposes of this Manufacturing Agreement and the MRD/Quality Agreement, “implementation” shall mean all the activities necessary to make New Labeling available for use for the final finishing (packaging) line.

(d) Lilly hereby grants to ViroPharma, for no additional consideration, a non-exclusive license to use the trademarks and or trade names owned by Lilly that are included in the Current Labeling solely to market, sell and promote the Marketed Product delivered by Lilly. The foregoing license will terminate, with respect to the Lilly logo, upon ViroPharma’s sale of all Marketed Product bearing the Current Labeling, including all such saleable returned Marketed Product. Lilly will not supply Marketed Products bearing the Lilly logo after the one (1) year anniversary of the Closing Date. It is the responsibility of ViroPharma to develop, and have available for use, the New Labeling by that deadline. Lilly will have no obligation to re-label or over-label any such Marketed Product packaged prior to the implementation of the New Labeling.

-24-

(e) The New Labeling and changes made thereto will be made in accordance with the procedures and timelines set forth in the MRD. ViroPharma will reimburse Lilly for any reasonable direct costs incurred by Lilly in order to implement the New Labeling and for any subsequent packaging and labeling change work required or otherwise requested by ViroPharma hereunder, including without limitation, commercially reasonable costs associated with the destruction of printed components rendered obsolete as a result of changes required by ViroPharma.

(f) The Parties acknowledge and agree that Lilly’s use of the Assigned Trademarks and Assigned Trade Dress (collectively the “Trademarks”) hereunder shall be for the sole purpose of its fulfillment obligations for the manufacture and supply of Marketed Product on behalf of ViroPharma and that such use of the Trademarks shall be in compliance with the strict quality control standards set forth herein. Lilly has no licensed right to use the Trademarks in the Territory without the written authority of ViroPharma. Prior to implementation of the New Labeling, Lilly shall use the Trademarks consistently and accurately, in the manner and form used by Lilly in connection with the Current Labeling and Marketed Product as of the Closing Date. With respect to the New Labeling and any subsequent changes thereto, Lilly shall use the Trademarks consistently and accurately, in the manner and form designated by ViroPharma.

5.2

Lot Numbering. Lilly’s lot numbers will be affixed on the containers for the Marketed Product and on each shipping carton in accordance with Applicable Laws.

5.3

Testing and Rejection of Delivered Marketed Product.

(a) Non-Conforming Marketed Product. ViroPharma will be entitled, at its cost and expense and using the test methods set forth in the NDA, to test any and all Marketed Product delivered to it hereunder to determine whether such

-25-

Marketed Product complies with the Specifications and the labeling requirements of Section 5.1. ViroPharma will use validated methods to test Marketed Product. ViroPharma will notify Lilly in writing promptly, and in any event not later than [***] after receipt thereof at a ViroPharma distribution center thereof if it rejects any Marketed Product delivered to it because such Marketed Product failed to meet the Specifications. If ViroPharma rejects any such Marketed Product Lilly and ViroPharma will conduct a joint investigation to determine the cause. Lilly shall have, at its request and at its expense, the opportunity to conduct its own tests on such rejected Marketed Product. Lilly will replace any properly rejected Marketed Product with Marketed Product which meets the Specifications within a commercially reasonable time and in any event, within [***] after ViroPharma’s notice of rejection and will deliver such replacement Marketed Product, at Lilly’s sole cost and expense, to ViroPharma. In addition, Lilly will, at Lilly’s sole cost and expense, arrange for all such rejected Marketed Product to be picked up promptly and, where applicable, destroyed in accordance with all Applicable Laws. ViroPharma will have no responsibility to Lilly for the Purchase Price of such nonconforming Marketed Product but will pay Lilly the Purchase Price for the replacement Marketed Product after delivery thereof in accordance with Section 2.4, above; provided, however, that to the extent ViroPharma previously paid for Marketed Product it properly rejected in accordance with this Section 5.3(a), ViroPharma will receive a credit against the Purchase Price for replacement Marketed Product if Lilly is able to supply same in accordance with this Manufacturing Agreement. Marketed Product properly rejected in accordance with this Section 5.3(a) will not be applied to the applicable Purchase Maximums or Purchase Minimums, or the purchase obligation set forth in Section 2.2, but replacement Marketed Product will be so applied.

(b) Disputed Marketed Product. Notwithstanding subsection (a), above, if following the joint investigation contemplated by (a) above, ViroPharma and Lilly disagree on whether any Marketed Product rejected by ViroPharma

-26-

pursuant to subsection (a), above, complies with the Specifications or on the methods for or results of testing of any of such rejected Marketed Product, an independent laboratory which is acceptable to both Parties will test the Marketed Product in dispute (“Disputed Marketed Product”) using the test methods set forth in the NDA, and any other applicable cGMP test method used by Lilly at the time the Disputed Marketed Product was manufactured, which tests will be validated by such laboratory independently. If such laboratory finds that the Disputed Marketed Product meets the Specifications, ViroPharma will pay the fees of such laboratory related to such testing and will promptly pay for the Disputed Marketed Product. If such laboratory finds that the Disputed Marketed Product fails to meet the Specifications, Lilly will pay the fees of such laboratory related to such testing and will promptly replace the Disputed Marketed Product in accordance with the preceding subsection (a). Both Parties hereby agree to accept and be bound by the findings of such independent laboratory.
