Customer shall promptly give Chiron written notice of any aspect in which Bulk Product was not so manufactured. Such notice should include the detailed reasons describing the alleged non-conformance. If Customer notifies Chiron of any such non-conformance, the matter of the invoice payment for the non-conforming batch shall be held in abeyance until the dispute is resolved. The parties shall in good faith attempt to resolve such dispute within thirty (30) days and if unable to do so, shall refer such outstanding dispute to the Dispute Resolution provision of this Agreement.

(iv) In the event that the manufacture of a portion of a Product lot fails to conform to the Procedures resulting from Chiron's negligence or misconduct, the Customer shall only pay Chiron a prorated fee only for the conforming portion of the lot. Chiron shall credit the Customer for the prorated cost of the non-conforming portion of the Other Materials. (v) The party that pays for the cost of the replacement bulk product defined in sections (i) through (iv) above shall also pay for the cost of disposal of the rejected Product.

INDICATES MATERIAL HAS BEEN OMITTED PURSUANT TO CONFIDENTIAL TREATMENT REQUEST, WHICH THE COMPANY HAS FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] PROJECT SCOPE CHANGES: EntreMed may request changes to the project scope or to its process by communicating such request in writing or email to the Chiron Project Manager. Chiron will work with EntreMed to determine whether such change will have a schedule or financial impact on the project. If it does, Chiron business development will prepare a change order documenting the change, cost and schedule impact and implement the change, to the extent practical, after the designated EntreMed representative approves the change order in writing and returns it to Chiron. Chiron will use reasonable effort to accommodate changes that do not negatively impact its regulatory license or cGMP status, other products or processes. PROCESS CHANGE IMPLEMENTATION: During large-scale development or cGMP runs, EntreMed may request process changes that have no impact on Chiron products. EntreMed recognizes that during cGMP runs, such changes will made in accordance with approved Chiron change control procedures and may result in a deviation being issued. EntreMed will communicate the requested change to Chiron project manager in writing on a form that the parties agree to prior to the start of the development runs. EntreMed is prohibited from requesting a change directly through an operator. If the Chiron project manager determines that the change is safe and will not jeopardize equipment, the change will be implemented immediately. Changes during production such as modifying a process control parameter or changing the sequence to operate a manual valve typically do not result in any cost impact unless such changes are to be made permanent resulting in a need to modify and approve SOPs. In the event that a change has a cost impact, such as a request to perform additional assays, the cost will be determined at the Additional Services Rate and documented as a change order after the run is completed. Chiron shall not change any processing parameters for the manufacture of the Product that could affect EntreMed's process validation, without prior written agreement from EntreMed. CUSTOM MANUFACTURING REPORTS: EntreMed may request that Chiron provide a custom manufacturing report for each lot or campaign. The reports would consolidate information from Chiron's standard lot package into a format specified by EntreMed. Time to develop, format and complete a custom report for each lot or campaign and for Chiron QA to review and approve such report would be additional services. 16 <PAGE> 33 [". . ."

RAW MATERIALS AND SUPPLIES: EntreMed will provide a preliminary Bill of Materials (BOM) and specifications/acceptable grades for required raw materials and supplies no later than the dates shown on the Project Schedule, Figure 2. Chiron will prepare the final Bill of Materials. Chiron will purchase raw materials, supplies and consumables in accordance with its approved procedures using EntreMed's specifications. Raw materials, supplies and consumables include all materials that are used in the production process such as the following: - Media - Glucose sources - Trace metals - Process and buffer chemicals - Chromatography resins - In-process filters and membranes - Disposable product contact tubing - Buffer bags, transport bags and bulk product containers Other materials used to support standard utilities and process operations such as pure water, clean air, HVAC, clean steam, gowning apparel are included in the Facility Use Fees further specified in Section 16. To minimize costs, Chiron will place one order for each raw material of sufficient quantity for the entire production campaign (including raw materials for equipment testing and sham runs), if practicable, and two extra VMF lots and two extra CMF lots for safety stock. During the production campaign, Chiron will order additional raw materials and supplies as required such that safety stocks for two extra VMF lots and two extra CMF lots will always be maintained. The Bill of Materials must be finalized at least 2 months prior to the start of production. Changes to the Bill of Materials within 2 months to the start of production could jeopardize the project schedule. If changes to the Bill of Materials result in raw materials not being available at the scheduled start of production and thus result in an idle facility, then EntreMed will pay Chiron the applicable facility idle fees specified in Section 16. Chiron will perform an identity "ID" test on incoming raw materials and supplies for their qualified vendors. Chiron will retain raw material samples in accordance with its approved procedures and the terms of this Agreement. OPTIONAL RAW MATERIAL VENDOR QUALIFICATION: For the qualification/validation lots, Chiron, or its contractor will perform certain compendial QC testing on incoming raw materials as agreed to by the Planning Team. Chiron will qualify new vendors required under this Agreement. This work would be performed only for new vendors or raw materials that have not previously been qualified by Chiron. Fees for the optional raw material vendor qualification and compendial testing will be treated as additional services by Chiron. 27 <PAGE> 44 [". . ."

ANALYTICAL: Chiron personnel may visit EntreMed, if required, and witness the methods at EntreMed's current contractor. EntreMed will then make available in-process analytical methods, listed on Table 3 as EntreMed's methods, to Chiron and train Chiron operators on the performance of such analytical methods. Transfer data may be utilized to support EntreMed's method validation. Chiron will perform all assays listed on Table 3 for all full scale development and cGMP lots with the exception that the working cell bank ID test will be performed only once for each bank that is sent to Chiron. For assays provided by EntreMed, as indicated in Table 3, the following system will apply to demonstrate equivalent assay performance at EntreMed and Chiron laboratories: |X| EntreMed will provide the standards (control reference standards including applicable protein pool samples and including final bulk product showing the range of ". . .") and Process Validation Protocols |X| Chiron will confirm acceptance of the control reference standards |X| Chiron will generate SOPs based on the protocols, if necessary |X| Chiron will then perform assays per EntreMed's protocols or Chiron's SOPs, as applicable |X| Chiron will provide the data summary to EntreMed as specified per EntreMed protocols or Chiron SOPs, as appropriate |X| Chiron will provide a copy of the raw data to EntreMed |X| EntreMed will write the equivalency/validation report For validated assays provided by EntreMed, Chiron will run the assays as mutually agreed to demonstrate that the assays perform equivalently at EntreMed and Chiron laboratories (equivalency studies). However, Chiron will not perform any assay validation testing or services such as sensitivity, robustness, limitation of quantitation, limitation of detection, and interday or intraday variability. For unvalidated assays provided by EntreMed, Chiron will perform co-validation services such as sensitivity, robustness, limitation of quantitation, limitation of detection, and interday or intraday variability, if requested by EntreMed in writing. If such co-validation services require more Chiron resources than the equivalency study described above, then the additional resources will be provided as additional services. For assays provided by Chiron, listed on Table 3, if any such assays require modification or development to perform properly with EntreMed's product and matrix, such work would be performed as additional services, if requested by EntreMed in writing. For assays provided by Chiron, listed on Table 3, Chiron will perform validation services such as sensitivity, robustness, limitation of quantitation, limitation of detection, and interday or intraday variability, if necessary, for use of the assay with EntreMed's process, and if requested by EntreMed in writing. Such assay validation services would be performed as additional services. 28 <PAGE> 45 [". . ."

Chiron will make reasonable efforts to report to EntreMed any concerns it identifies regarding the technology, the robustness and scalability of EntreMed's process based on its past experience, observation of the process at EntreMed's current contractor and bench-scale testing of the process at Chiron. Chiron will advise EntreMed on how 31 <PAGE> 48 [". . ." INDICATES MATERIAL HAS BEEN OMITTED PURSUANT TO CONFIDENTIAL TREATMENT REQUEST, WHICH THE COMPANY HAS FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] particular concerns may be addressed. However, it will be EntreMed's decision whether to implement any of Chiron's advice. Unresolved issues will be referred to the Management Committee. Chiron, in consultation with EntreMed and drawing upon information provided by EntreMed's TTP, will develop a 10,000 L Technology Transfer Report (TTR) defining the process in detail to Chiron manufacturing. The report will specify at the 10,000 L scale for VMF and CMF: A) the grade, raw material list and amounts of raw materials to be used at 10,000 L scale (Bill of Material (BOM)) and the order in which they should be added B) the process operating parameter ranges, e.g., ". . ." and expected limits for process variables, e.g., cell density harvest should be ". . ." C) the necessary in-process assays (See Table 3) and the frequency of data collection D) packed column performance criteria for 10,000 L An acceptable 10,000 L technology transfer report must be finalized and mutually agreed to by the Planning Team at least five weeks prior to the start of the 10,000 L Development runs. The date by which the TTR needs to be approved will be agreed to by the Planning Team and will be highlighted in the detail project plan. Substantive changes to the TTR within five weeks to the start of production could jeopardize the project schedule. If EntreMed requests changes to the TTR that could delay the start of production, the matter will be referred to the Management Committee for resolution. If appropriate, EntreMed will pay Chiron the applicable facility idle fees specified in Section 16. One or more Chiron process development representatives may visit EntreMed's manufacturing facility to observe EntreMed's 2,000 L bulk Endostatin manufacturing process. One or more Chiron process development representatives will participate in VMF and CMF facility walk throughs prior to the development runs and will work with EntreMed on the successful development of BPRs, MPRs and SOPs relevant to EntreMed's process Chiron will be responsible for sharing technology transfer responsibilities and advising EntreMed about how the process could be modified to improve robustness or scalability but Chiron will not be responsible for changing the process or undertaking any specific process development work unless mutually agreed to as additional services. MINIMUM ENTREMED PERSONNEL SUPPORT AT CHIRON: 1. EntreMed technical representatives will reasonably train all Chiron personnel in the use of EntreMed's assays prior to the start of bench scale runs. 2. EntreMed technical representatives should be available, whenever reasonably necessary, for consultation via telephone or at Chiron, if required, during the bench scale runs. 3. EntreMed technical representatives will participate in VMF and CMF facility walk throughs prior to the development runs to review and advise Chiron on the BPRs, MPRs and SOPs relevant to EntreMed's process. 32 <PAGE> 49 [". . ." INDICATES MATERIAL HAS BEEN OMITTED PURSUANT TO CONFIDENTIAL TREATMENT REQUEST, WHICH THE COMPANY HAS FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION] 4. EntreMed will make technical representatives or its designees available during the development runs. The technical representatives will provide process advice, make process related decisions such as selecting setting for process parameters based on analytical results, make go/no go production decisions, provide support for trouble shooting and help coordinate sampling programs. Some portions of the development runs shall occur during off-shifts or night shifts. Chiron strongly prefers having the EntreMed technical representatives onsite. If it is not possible to have the technical representatives onsite, EntreMed will ensure that the technical representatives are available by cell phone or other modes of communication. The technical representatives must be empowered to make decisions about the process. Such decisions shall be immediately documented in writing to Chiron. 5. EntreMed may provide technical representatives during the VMF and CMF cGMP runs to provide process advice, observe production, make go/no go production decisions, provide support for the trouble shooting. 6. EntreMed's participation in the above activities should be discussed and agreed to by the Planning Team. BENCH SCALE RUNS: Chiron will perform up to ". . ." (if necessary) non-cGMP 10 L fermentor runs executed in accordance with 10 L protocol and procedures supplied by EntreMed. The runs will be performed at Chiron's Emeryville process development facilities. The purpose will be to monitor ". . ." and ". . ." during the run and to mutually compare the results to data generated by EntreMed during runs of similar scale to determine whether the process and assays were transferred successfully to Chiron at bench scale. Chiron process development will prepare a brief (approximate 1 page) summary report for EntreMed outlining the work performed, results and conclusions for each fermentor run. Chiron will use the bench scale harvest broth to perform up to ". . ." (if necessary) non-cGMP downstream processing runs (DSP). Chiron process development will prepare a brief (approximate 1 page) summary report for EntreMed outlining the work performed, results and conclusions for each DSP run. If the Planning Team so desires, a portion of the 10 liter fermentation harvest and purified bulk material produced by Chiron will be sent to EntreMed for further processing and characterization. EntreMed will advise Chiron if any unexpected results are determined. If unexpected results are determined, the parties will decide whether to perform additional 10 L fermentation and downstream processing runs and as an additional service prior to the initial VMF development run. However, performance of additional 10 L fermentation and downstream processing runs could result in delay of the VMF and CMF development runs Upon completion of the bench scale runs, EntreMed shall authorize Chiron to initiate the development runs, at its discretion. However, EntreMed shall pay Chiron the applicable Facility Delay Fees specified in Section16 if EntreMed requests a delay of the scheduled VMF or CMF development runs and Chiron has executed the bench scale runs per agreed upon protocols and procedures. 33 <PAGE> 50 [". . ."

The process development services could include bench scale runs to study: ". . ." The development services could include work to determine whether ". . ." EntreMed would pay Chiron to perform these services as additional services. The services would be subject to staff availability and mutual agreement on scope, schedule, cost and other necessary terms. Chiron may credit a portion of the fee for these development services towards future full-scale manufacturing fees. DEVELOPMENT RUNS: The ". . ." development runs (The "Development Runs") scheduled for VMF will proceed all the way through the initial chromatography column, if possible. If ". . ." lots at VMF generate useable bulk, such lots will be used to perform ". . ." development runs at CMF. If only ". . ." Chiron may perform additional development runs as additional services, if requested by EntreMed. Chiron will take samples from the VMF development runs as requested by EntreMed and then Chiron, after consultation with EntreMed, will dispose of the development Product that is not processed further at the VMF or CMF. Upon completion of the development run(s), EntreMed shall authorize Chiron to initiate the cGMP runs, at its discretion. However, EntreMed shall pay Chiron the applicable Facility Delay Fees specified in Section16 if EntreMed requests a delay of the scheduled VMF or CMF cGMP runs and Chiron has executed at least one integrated development run per agreed upon procedures. CHIRON PROCESS DEVELOPMENT SUPPORT AT VMF AND CMF: Chiron fermentation and downstream processing specialists will provide up to a total of five (5) weeks of advisory support including trouble shooting during the development and/or cGMP runs. The weeks of support shall be allocated between the VMF and CMF as mutually agreed upon by the Planning Team. The specialists will arrange their schedules such that one specialist will be onsite at VMF or CMF at all times during the development runs (24 hours/day, coverage Monday - Friday). Chiron specialists will provide advice based on past experience. EntreMed will decide whether to follow any of Chiron's advice. During the development runs, Chiron Process Development staff will advise the EntreMed technical representative how to maximize fermentor working volume with the process constraints provided by EntreMed. However, such advice could increase risk of losing a run, e.g., a higher working volume than initially agreed upon could cause overflow of the fermentor and loss of the run at EntreMed's cost. It will be the EntreMed representative's sole responsibility to decide whether to act upon the advice and to communicate the desire to implement a change to Chiron by signing the appropriate change document. The change document must be signed by the EntreMed representative prior to Chiron implementing the change. PROCESS VALIDATION: ". . .". Therefore, EntreMed will need to specify a validatable process step(s) such as in-line filtration, that reduces live host organisms to a pre-approved Chiron level for material that is brought into the CMF. Chiron will review and approve the validation procedure in advance to assure that it is acceptable 34 <PAGE> 51 [". . ."

ENVIRONMENTAL AND SAFETY: EntreMed shall supply Chiron with a material safety data sheet for the Endostatin drug substance and materials supplied by EntreMed. Chiron will be responsible for developing, implementing and following safety procedures for the handling and manufacture of the drug substance and waste handling procedures for the generation, treatment, storage and treatment or disposal of wastes relating thereto, that comply with all material federal and state environmental and occupational safety and health requirements and with voluntary NIH RAC guidelines for biotechnology. Appropriately trained Chiron EH&S staff will provide sufficient support to Chiron operations for production of the Product. EFFLUENT DISCHARGE: EntreMed will provide Chiron with representative samples of fermentor broth and certain purification waste streams. Sample volumes up to two (2) liters may be required depending on the number of assays/screens required to obtain required approval to discharge or ship the wastes to an acceptable contractor. If not possible, Chiron will attempt to use samples from the fermentation and downstream processing bench runs. Chiron will via a contract service, use the samples to perform waste stream characterization. Waste streams generated at VMF and CMF while manufacturing the Product for EntreMed will be handled per Chiron's approved procedures. In the event that EntreMed's process can not use Chiron's validated cleaning methods for VMF or CMF process equipment or chromatography columns and introduces new regulated hazardous constituents into the VMF or CMF waste discharges, Chiron will need to evaluate the effluents for the augmented cleaning processes before the full-scale development or cGMP runs can be completed. If these wastes are not dischargable to Chiron's sanitary systems at VMF or CMF, Chiron will develop new collection methods as additional services. 46 <PAGE> 67 [". . ."
