For this purpose, the meaning of the word "control" shall mean the ownership of fifty percent (50%) or more of the voting shares or interest of such corporation or business entity, or any corporation or business entity in which the party seeking to demonstrate Affiliate status can demonstrate, even though the extent of ownership of such shares or interest in such corporation or business entity is less than (50%), that the operation and management of such corporation or business entity is carried out in conformity with the particular party's standing policy; such corporation or business entity to be deemed an Affiliate only so long as such ownership of voting shares or interest or adherence to such standing policy continues. 1.2 "Compound" shall have the meaning set forth in Section 1.4(i) of the License Agreement, provided, that if either party hereto desires to change a compound or add an additional compound or compounds, the parties agree to negotiate in good faith an amendment to this Agreement to include such changed or additional compound(s) on mutually acceptable terms. 1.3 "Compound Specifications" shall mean the specifications for Compound which shall be reasonably agreed upon from time to time by ALLERGAN and XOMA(US) after consultation and which shall be comparable in scope to the specifications for Compound provided by XOMA(US) to ALLERGAN on the date hereof and identified as "Master Report of Bill of Testing (BOT) for rBPI , Effective Date: 4/13/99 R05." 1.4 "FDA" shall mean the U.S. Food & Drug Administration. 1.5 "Field" shall have the meaning set forth in the License Agreement. 1.6 "Major Market Country" shall have the meaning set forth in the License Agreement. 1.7 "NDA" shall mean a New Drug Application filed under the U.S. Food, Drug and Cosmetic Act and the regulations thereunder. 1.8 "Products" shall have the meaning set forth in the License Agreement. 1.9 "Third Party" shall mean any party other than XOMA(US), XOMA(US)'s Affiliates, ALLERGAN or ALLERGAN's Affiliates. ARTICLE II - COMPOUND SUPPLY: 2.1 Supply. During the term of this Agreement, ALLERGAN shall be obligated to purchase exclusively from XOMA(US) and XOMA(US) shall be obligated to supply exclusively to ALLERGAN, Compound for use in the Field. The parties agree to negotiate for an extension of this exclusive purchase obligation during the one year period preceding the expiration of the aforementioned term. However, any agreement to such an extension is within each party's sole business judgment. In consideration of ALLERGAN's agreement to exclusively purchase Compound from XOMA(US) for use in the Field, XOMA(US) agrees, at XOMA(US)'s sole expense, to validate (a) an approved source of Compound prior to the beginning of the first Phase III clinical trial of the Product in the United States or the equivalent of a Phase III trial in any other Major Market Country, and (b) a second approved source of Compound prior to the filing of an NDA or its equivalent with the FDA or other drug regulatory agency, respectively, in a Major Market Country. Such second source may be a second manufacturing facility of XOMA(US) or its Affiliates. In order for a source of Compound to be considered a validated source under this Section 2.1, such source must be capable of supplying compound in accordance with the Compound Specifications and requirements of Section 2.6 hereof. Thereafter, and during the term of XOMA(US)'s obligation to supply compound to ALLERGAN under this Section 2.1, XOMA(US) will maintain both such first and second source of Compound in condition to supply Compound in accordance with the Compound Specifications and requirements of Section 2.6, hereof. In lieu of establishing and maintaining a second source, XOMA(US) may maintain an inventory of Compound, designated specifically for ALLERGAN, in an amount at least equal to [*] of ALLERGAN's forecasted needs for the ensuing twelve (12) months. Prior to the filing of an NDA or its equivalent with the FDA or other drug regulatory agency, respectively, in a Major Market Country, the parties shall confer and in good faith establish an initial forecast for the ensuing twelve (12) months, which shall be updated quarterly as provided in Section 2.7. On reasonable notice and during normal business hours, XOMA(US) shall allow an ALLERGAN representative and an FDA and/or other health regulatory representative access to the manufacturing, filling, packaging, labeling, warehousing, storage and quality control 2 equipment and facilities utilized with respect to Compound being produced pursuant to this Agreement, and to all applicable records relating to manufacturing, filling, labeling, warehousing, storage, packaging, and quality control of Compound being produced pursuant to this Agreement. XOMA(US) shall notify ALLERGAN of any such FDA inspection or inspections by any other regulatory health agency related to Compound being produced pursuant to this Agreement and shall allow an ALLERGAN representative to be present during same. 2.2 Price. ALLERGAN shall pay XOMA(US) for Compound a price of [*]. 2.3 Records. XOMA(US) shall maintain and keep for a period of at least three (3) years complete and accurate records in sufficient detail to enable its actual cost of manufacture to be determined. 2.4 Audits. Upon the request of ALLERGAN, but not exceeding once in any one (1) year period, XOMA(US) shall permit an independent certified accountant, selected by ALLERGAN and acceptable to XOMA(US), which acceptance shall not be unreasonably withheld, to have access to such records of XOMA(US) as may be necessary to verify the actual cost of manufacture of the Compound. Said independent certified accountant shall verify to ALLERGAN only the actual cost of manufacture and disclose no other information revealed in its audit. Any such audit of records shall be at ALLERGAN's expense; provided, that in the event such examination discloses an overpayment by ALLERGAN of more than five percent (5%), XOMA(US) shall pay the expense of such audit. Any overpayment shall be repaid promptly to ALLERGAN, plus interest at the commercial prime lending rate of the Bank of America until the date paid. 2.5 Payment Terms. Payment to XOMA(US) for any supply of Compound shall be due and payable thirty (30) days after shipment by XOMA(US) to ALLERGAN of such Compound. 2.6 Compound Supply. XOMA(US) shall supply exclusively all of ALLERGAN's requirements of the Compound, in accordance with Section 2.7 below, to enable ALLERGAN to manufacture the Products. If XOMA(US) is unable to supply [*] of ALLERGAN's requirements of the Compound for more than ninety (90)days, ALLERGAN shall have the right to manufacture or purchase from Third Parties its requirement of Compound. XOMA(US) shall cooperate in obtaining such alternate supply source, including, without limitation, transferring such technology and know-how, and license rights as are reasonably necessary for ALLERGAN or a third party to manufacture Compound. 2.7 Orders; Forecasts. At least ninety (90) days prior to the start of each calendar quarter, ALLERGAN shall provide XOMA(US) with a purchase order for the total amount of the Compound to be ordered for shipment during each month of such quarter and an estimate of its Compound requirements for each of the next three (3) quarters (each such estimate updating previous estimates and adding an estimate for the next succeeding quarter). Each quarterly purchase order will be within [*] of the preceding quarter's estimate for such quarter. XOMA(US) shall ship Compound to a facility or facilities designated by ALLERGAN within each such month of such quarter after the receipt of such purchase order from ALLERGAN. Title to the Compound shall pass to ALLERGAN upon receipt by ALLERGAN at such facility. 3 2.8 Warranties.

XOMA(US) shall deliver a certificate of analysis with each lot of Compound specifying the results of analysis to show conformance with the applicable Compound Specifications. Upon receipt, each lot of Compound shall be tested by ALLERGAN, and thereafter ALLERGAN shall provide XOMA(US) with written notice of its acceptance or rejection of the lot. Each such lot shall be deemed accepted by ALLERGAN (subject to Section 5.2) unless XOMA(US) receives written notice of rejection of the lot (due to the failure of Compound to comply with the Compound Specifications as of the time the lot was received by ALLERGAN) within thirty (30) days after ALLERGAN's receipt of the Compound. At ALLERGAN's option, XOMA(US) shall replace any nonconforming Compound at XOMA(US)'s expense with a like amount of the Compound conforming to the Compound Specifications. For purposes hereof, replacement may include reprocessing of the Compound, so long as such reprocessing is mutually agreed upon by the parties and conforms to applicable law and regulation, including FDA current Good Manufacturing Practices. If XOMA(US) does not agree with ALLERGAN that the supplied lot fails to conform to the Compound Specifications, the matter may be submitted to an independent laboratory acceptable to both parties in order to resolve the discrepancy in the analysis of the Compound rejected. The cost of assay by the independent laboratory shall be borne by the party whose analysis was in error. ALLERGAN shall procure or produce, and where appropriate shall quality control test, all other raw materials and packaging components needed to manufacture the Products. 2.9 Development Supplies.
