SALE AND DELIVERY OF PRODUCT

Section 2.1 Subject to the terms and conditions set forth in this Agreement, PPG agrees to Prepare and sell, and MedImmune Oncology agrees to purchase from PPG, the Product as follows:

Prior to the beginning of each calendar quarter, MedImmune Oncology shall provide to PPG, in writing, a (CONFIDENTIAL TREATMENT REQUESTED) forecast of its requirements for deliveries of the Product during the next (CONFIDENTIAL TREATMENT REQUESTED) (hereinafter the "Delivery Schedule"). The quantities forecast for delivery in the (CONFIDENTIAL TREATMENT REQUESTED) in a Delivery Schedule shall be firm commitments to purchase and sell; and the (CONFIDENTIAL TREATMENT REQUESTED) included in a Delivery Schedule shall be for planning purposes and may be revised up or down by MedImmune Oncology. Exhibit "A" sets forth MedImmune Oncology's non-binding requirements forecast for the Contract Years 2001-2003.

Section 2.2 PPG agrees, at the request of MedImmune Oncology, to provide Product at the agreed upon price set forth in the Price Schedule attached hereto as Exhibit "B" and subject to the provisions of Section 3.1.

Section 2.3 Subject to Section 2.5, PPG shall provide (CONFIDENTIAL TREATMENT REQUESTED) to (CONFIDENTIAL TREATMENT REQUESTED) of MedImmune Oncology's requirements for the Product, at MedImmune Oncology's option. Subject to Section 2.5, MedImmune Oncology shall purchase from PPG a minimum of (CONFIDENTIAL TREATMENT REQUESTED) to (CONFIDENTIAL TREATMENT REQUESTED) of MedImmune Oncology's global requirements for the Product, provided however, that PPG may elect to qualify a second manufacturing location for production of Product by informing of its intent to do so in writing. Within 90 days of such notification, PPG will provide to MedImmune documentation which describes PPG's qualification protocols and validation plans. PPG and MedImmune will cooperate to complete such qualification in a timely manner. Upon successful qualification of the alternate manufacturing location by MedImmune, MedImmune shall be obligated to purchase (CONFIDENTIAL TREATMENT REQUESTED) of MedImmune Oncology's global requirement for Product.

Section 2.4 PPG shall at all times maintain a minimum inventory of at least (CONFIDENTIAL TREATMENT REQUESTED) of the amount of the Product purchased by MedImmune Oncology during the preceding (CONFIDENTIAL TREATMENT REQUESTED). PPG shall at all times maintain a minimum annual capacity reserved for production of the Product for MedImmune Oncology of the quantity of Product specified for delivery in the most recent Delivery Schedule. Notwithstanding anything to the contrary in this Section 2.3, should PPG be required to replace Product pursuant to its obligations in Article 4, PPG may utilize the inventory of the Product even though that may result in a temporary situation in which inventory is less than required by this Section 2.4. PPG shall rebuild the

inventory to once again meet the requirements of this Section 2.4 within (CONFIDENTIAL TREATMENT REQUESTED) days of removing Product to use as replacement Product.

Section 2.5 If PPG has not qualified an alternative manufacturing site subject to Section 2.3, MedImmune Oncology may qualify an alternative source(s) of supply other than PPG and may secure Product from such alternative source(s) for amounts in excess of (CONFIDENTIAL TREATMENT REQUESTED) of its requirements. MedImmune Oncology shall not make the alternative source(s) MedImmune Oncology's principal supplier of Product unless PPG has materially failed to meet MedImmune Oncology's orders in a period of more than (CONFIDENTIAL TREATMENT REQUESTED) or this Agreement is terminated or has by its terms expired. After (CONFIDENTIAL TREATMENT REQUESTED) in which PPG has materially failed to meet MedImmune Oncology's orders, both parties agree that MedImmune Oncology may use an alternate source to supply MedImmune Oncology's needs until PPG is able to again furnish MedImmune Oncology's needs.

Section 2.6 PPG agrees to sell the Product exclusively to MedImmune for pharmaceutical applications. PPG agrees that during the term of this Agreement and for a period of (CONFIDENTIAL TREATMENT REQUESTED) thereafter, it will not compete, or assist third parties to compete, directly or indirectly with MedImmune Oncology in the sale of the Product.

Section 2.7 MedImmune Oncology shall submit purchase orders for Product to PPG at least (CONFIDENTIAL TREATMENT REQUESTED) prior to the date of shipment specified therein. MedImmune Oncology's purchase orders shall (i) reference this Agreement; (ii) be submitted in writing; (iii) state the quantity of Product ordered; (iv) specify the delivery location; and (v) state the desired date of shipment. In no event shall the use of any form of purchase order be effective to vary, alter, modify or add to the terms and provisions of this Agreement; nor will the acceptance of any such purchase order have the effect of substituting the provisions set forth on such form for the provisions contained in this Agreement. MedImmune Oncology may reschedule such purchase order no later than (CONFIDENTIAL TREATMENT REQUESTED) prior to the date of scheduled manufacturing. In no event shall MedImmune Oncology's right to reschedule such Purchase Order abrogate any of its obligations under Section 2.1.

Section 2.8 PPG shall exercise reasonable, diligent efforts to ship Product in the quantities and on the dates specified in MedImmune Oncology's purchase orders. Sales of Product by PPG to MedImmune Oncology shall be made CIP (as in Incoterms 1990), to MedImmune Oncology's facility in Nijmegen, the Netherlands, or such other location as may be specified by MedImmune Oncology to PPG from time to time hereunder.

ARTICLE III

PAYMENT TERMS

Section 3.1 The Base Prices to be paid by MedImmune Oncology for quantities of Product purchased pursuant to this Agreement are set forth in Exhibit "B", except for freight and insurance which will be billed (CONFIDENTIAL TREATMENT REQUESTED). The prices set forth on Exhibit "B" shall be subject to the following adjustments, as applicable:

PPG and MedImmune Oncology will adjust the prices in Exhibit B such that any benefit or loss due to the change in exchange rate will be shared equally by the parties according to the following:

Average Exchange Rate ("AER") is defined as the average Euro per US$ exchange rate which has prevailed for the previous (CONFIDENTIAL TREATMENT REQUESTED) prior to the date of invoicing.

"Invoice Price" is defined as such:

For invoices for which the AER is greater than or equal to (CONFIDENTIAL TREATMENT REQUESTED) Euro per US$ and less than or equal to (CONFIDENTIAL TREATMENT REQUESTED) per US$ the Invoice Price is equal to (CONFIDENTIAL TREATMENT REQUESTED) divided by the AER multiplied by the Base Price then in effect

For invoices for which the AER is greater than (CONFIDENTIAL TREATMENT REQUESTED) the Invoice Price is equal to (CONFIDENTIAL TREATMENT REQUESTED) multiplied by the Base Price then in effect.

For invoices for which the AER is less than (CONFIDENTIAL TREATMENT REQUESTED) the Invoice Price is equal to (CONFIDENTIAL TREATMENT REQUESTED) multiplied by the Base Price then in effect.

In summary:

For AER>(CONFIDENTIAL TREATMENT REQUESTED) Invoice price = (CONFIDENTIAL TREATMENT REQUESTED)× Base Price in effect

For (CONFIDENTIAL TREATMENT REQUESTED)<AER<(CONFIDENTIAL TREATMENT REQUESTED) Invoice price= (CONFIDENTIAL TREATMENT REQUESTED)/AER × Base Price in effect

For AER<(CONFIDENTIAL TREATMENT REQUESTED) Invoice price = (CONFIDENTIAL TREATMENT REQUESTED) × Base Price in effect

In the event that MedImmune Oncology makes changes to the Specifications which result in material increases in the cost to PPG to Prepare the Product, PPG and MedImmune Oncology shall negotiate in good faith an appropriate and reasonable price adjustment. In the event that the regulatory authorities other than the regulatory authorities of the United States, the EC countries or Japan, require additional cGMP requirements or changes to the Specifications in order to allow commercialization of Product in their respective countries, the parties shall negotiate in good faith an appropriate and reasonable price adjustment relating solely to quantities of Product for which such changes are necessary.

In the event that the parties do not agree on such price adjustment, then both parties will appoint a mutually acceptable independent expert whose findings will be binding on both PPG and MedImmune Oncology. Said expert shall transmit to both parties its findings within three months from the date of its appointment. If the parties are unable to agree on an independent expert, the matter shall be settled in accordance with Section 12.3 hereof.

Section 3.2 All prices of Product shall be on the basis of (CONFIDENTIAL TREATMENT REQUESTED) as in Incoterms 1990.

Section 3.3 The purchase price for Product shall be paid to PPG no later than (CONFIDENTIAL TREATMENT REQUESTED) days after the date of PPG's invoice to MedImmune Oncology. In no event shall PPG invoice MedImmune Oncology for the Product prior to delivery. All invoices from PPG to MedImmune Oncology covering Product shipped to MedImmune Oncology shall be stated in, and all payments to PPG by MedImmune Oncology shall be made in United States Dollars (US$). However, the parties hereto may agree at the beginning of each Contract Year that such invoices and payments will be in European Monetary Units (Euro), provided, however, that said prices may be adjusted by mutual agreement of the parties by an amount sufficient to cover PPG'S currency exchange risk and costs.

In the event that the Euro to US$ exchange rate is greater than (CONFIDENTIAL TREATMENT REQUESTED) or less than (CONFIDENTIAL TREATMENT REQUESTED) for

more than (CONFIDENTIAL TREATMENT REQUESTED), then either party may request a renegotiation of the Base Prices in Exhibit "B" in writing to the other party. Both parties will commence such negotiations within 30 days of receipt of the written request. If the parties fail to agree to a modification of the base prices within 60 days of commencement of the negotiation, then the dispute will be settled in accordance with Section 12.3.

Section 3.4 Payments due to PPG shall be made by wire transfer or by a mutually agreeable method to the bank account of PPG of which PPG shall advise MedImmune Oncology from time to time.

ARTICLE IV

MANUFACTURE AND SUPPLY

Section 4.1 Prior to the date of the Prior Agreement, MedImmune Oncology (then U.S. Bioscience, Inc.) transferred to PPG, and PPG hereby acknowledges receipt of, copies of MedImmune Oncology's specifications for the manufacture and testing of the Product, and such specifications have been revised from time to time under the Prior Agreement. The current specifications for the Product are attached hereto as Exhibit "C" and made a part hereof (such specifications, as revised in accordance with this Section 4.1, hereinafter being defined as the "Specifications"). The Preparation of the Product shall be carried out by PPG in accordance with applicable cGMPs and established quality standards. The Product shall meet Specifications. MedImmune Oncology shall provide PPG with all revisions to the Specifications in a timely manner after such revisions are approved by MedImmune Oncology, as appropriate, such revisions to be reasonably required for the Product. All revisions or deviations from Specifications for Product must be made in accordance with the Change Control Procedures set forth in Exhibit "D".

Section 4.2 PPG shall prepare and make available to MedImmune Oncology for review and comment comprehensive and complete documentation including the Drug Master File(s) with regard to the manufacture and testing of Product which will include, but not be limited to, testing of all raw materials, in-process and finished product applications; and review of master and working batch records for processing and packaging and all supporting analytical documentation. Such documentation shall be in a format consistent with cGMP's or FDA or other regulatory agencies requirements, and shall be prepared with respect to the manufacture of each batch of Product.

Section 4.3 PPG shall prepare and maintain a current master production batch record in English. At the time of execution of this Agreement, PPG shall provide MedImmune Oncology with a copy of the then current master production batch record in English. Thereafter, PPG shall provide to MedImmune Oncology any updates of this master record in English within (CONFIDENTIAL TREATMENT REQUESTED) of any such update being submitted. PPG shall not change the master production batch record without the prior written approval of MedImmune Oncology.

Section 4.4 For each batch Prepared, PPG shall provide MedImmune Oncology with a certificate of analysis and a certificate of compliance, specifically providing that the Product meets Specifications, in the English language, for the Product no later than (CONFIDENTIAL TREATMENT REQUESTED) after completion of manufacture of such batch.

Section 4.5 Within (CONFIDENTIAL TREATMENT REQUESTED) from receipt by MedImmune Oncology of the certificate of analysis for Product set forth in Section 4.4, MedImmune Oncology shall notify PPG in writing whether it approves of the release of Product for shipment. Upon receipt of such notification from MedImmune Oncology, PPG shall within one (1) week ship the certificated amount of Product to MedImmune Oncology's designee.

MedImmune Oncology shall confirm to PPG in writing within (CONFIDENTIAL TREATMENT REQUESTED) of arrival of a shipment of Product, the identity and amount of Product received, and

condition of the shipment based solely upon a visual inspection. Such MedImmune Oncology confirmation shall not constitute acceptance of the Product, nor shall it be construed as any indication of whether or not the Product conforms to Specifications.

Section 4.6 MedImmune Oncology or its designee shall have (CONFIDENTIAL TREATMENT REQUESTED) after shipment to inspect each shipment of Product to determine whether the Product included in such shipment conforms to the Specifications. MedImmune Oncology shall promptly give PPG written notice of any aspect in which Product fails to conform to Specifications. If MedImmune Oncology fails to notify PPG of any nonconformity within such (CONFIDENTIAL TREATMENT REQUESTED) period, MedImmune Oncology shall be deemed to have accepted the Product as shipped, provided, however, that with respect to any nonconformity due to latent defects, MedImmune Oncology shall be entitled to reject the nonconforming Product within (CONFIDENTIAL TREATMENT REQUESTED) after discovering the latent defects. In the event of contestation of quality by MedImmune Oncology as provided in this Section and that such contestation is not accepted by PPG, a sample of the contested batch sealed by PPG in compliance with applicable regulations shall be submitted by PPG to a relevant state approved unrelated and independent laboratory, mutually acceptable to both parties, and the check assay of said laboratory shall be accepted by the two parties as final and binding. The cost of said analysis made by the laboratory shall be borne by the failing party.

If any production batches of the Product fail to meet the Specifications as evidenced by the laboratory check assay, MedImmune Oncology shall have the right to return such batches, in which case the cost of the rejected batches (including raw materials, labor, manufacturing overhead and quality control) or, if applicable, the cost of any work (any rework not included in the Drug Manufacturing File must be approved in advance by MedImmune Oncology) will be borne by PPG unless such failure is due to the negligence of MedImmune Oncology. In the event that MedImmune Oncology rejects or returns any batch of Product pursuant to this Section, it shall receive replacement of such batch. In no event shall MedImmune Oncology's damages for rejected Product batches exceed (CONFIDENTIAL TREATMENT REQUESTED).

Section 4.7 PPG shall make its best reasonable efforts to replace Product as quickly as possible but in no case more than (CONFIDENTIAL TREATMENT REQUESTED) after notification of MedImmune Oncology of nonconformity pursuant to Section 4.6.

Section 4.8 In the event the check assay made by the laboratory as provided in Section 4.6 hereabove concludes the nonconformity of the Product, MedImmune Oncology and PPG shall meet immediately to agree upon the corrective actions, if any, to be implemented. PPG will cease further production of the Product until MedImmune Oncology and PPG formally agree in writing on such corrective actions. PPG may at its own risk continue to produce Product during this period with no obligation to MedImmune Oncology. Should MedImmune Oncology desire to have Product produced while the investigation is in process, MedImmune Oncology will be responsible for the fees for service of PPG whether the batch is accepted or not. Should PPG be required by MedImmune Oncology to produce any experimental batches of Product to elucidate or resolve the source of the batch rejection, xxxxxxxx for these batches will be separate from and exclusive of the fees stated in the attachment.

Section 4.9 PPG shall provide access to information and support needed during investigations addressing customer complaints and/or recalls. All documents and updates with regard to the Preparation of the Product which are required by any regulatory agency shall be provided by PPG, and PPG shall submit to all inquiries and inspections by such regulatory agencies. All documents provided by PPG to any regulatory agency shall be provided to MedImmune Oncology in advance, if feasible, and in no case shall such documents be provided to MedImmune Oncology more than two (2) days after such documents are provided to any regulatory agency.

Section 4.10 PPG shall properly dispose of all manufacturing waste and associated contaminated materials in accordance with all applicable laws, including French laws and environmental regulations. Upon MedImmune Oncology's request, PPG shall supply to the FDA or any official government agency an official statement, a model of which is attached hereto as Exhibit "E" stating that PPG is in conformance with relevant environmental regulations. PPG shall provide at the request of MedImmune Oncology from time to time a letter from the appropriate governmental authority certifying that the site is in compliance with environmental laws applicable to PPG.
