Should GalaGen, at any time during the course of this Agreement, have reason to believe that it will be unable to meet Wyeth-Ayerst's requested delivery dates, GalaGen will promptly notify Wyeth-Ayerst in writing setting forth the reasons for the delay. Such notification will not be deemed a waiver of GalaGen's obligation set forth in Section 4.3(b). In connection therewith: (a) If at any time GalaGen experiences a shortage of Ingredient supply and the available supplies of Ingredient are not sufficient to satisfy all of Wyeth-Ayerst's requirements for the Ingredient, GalaGen shall allocate its available worldwide supplies (including inventory in excess of customary supplies) first to Wyeth-Ayerst based on Wyeth-Ayerst's binding forecasts and any excess supplies of Ingredient may thereafter be allocated among its own requirements and those of its licensees and distributors. (b) If at any time GalaGen is of the opinion that it may not be able to meet future binding orders from Wyeth-Ayerst for Ingredient (including, but not limited to a situation where as a result of any intellectual property litigation GalaGen chooses not to supply Ingredient) it shall notify Wyeth-Ayerst in writing, and the Parties shall in good faith cooperate and endeavor to make appropriate arrangements for a continuous and adequate supply of Ingredient from GalaGen to Wyeth-Ayerst. 4.4 APPOINTMENT OF WYETH-AYERST AS MANUFACTURER. 4.4.1 Subject to terms and provisions of this Agreement, including, without limitation, GalaGen's right to manufacture the Ingredient for supply to Wyeth-Ayerst, GalaGen hereby grants to Wyeth-Ayerst a non-exclusive, perpetual, world-wide, royalty-free license to manufacture the Ingredient for use by Wyeth-Ayerst in accordance with the provisions of the License Agreement. Consistent with GalaGen's obligations under Section 2.3.4 if GalaGen is unable to supply at least [**CONFIDENTIAL TREATMENT 11 REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] of the quantities of Ingredient ordered by Wyeth-Ayerst in any two (2) consecutive Calendar Quarters, based on Wyeth-Ayerst's good faith estimates of its future requirements, Wyeth-Ayerst shall be relieved of its obligation to purchase that portion of its requirements of Ingredient from GalaGen that GalaGen is unable to supply, until such inability to supply has ceased and GalaGen may resume the manufacture of Wyeth-Ayerst's requirements of the Ingredient pursuant to Section 4.5 hereof, and Wyeth-Ayerst shall have the right, under the license granted in this Section 4.4.1, to manufacture, or have manufactured, such portion of the Ingredient that GalaGen is unable to supply. GalaGen has the right to approve, in advance, any Third Party manufacturer utilized by Wyeth-Ayerst pursuant to this Section 4.4.1, PROVIDED, HOWEVER, that GalaGen's approval shall not be unreasonably withheld and shall be communicated to Wyeth-Ayerst within ten (10) days of notice from Wyeth-Ayerst to GalaGen. If the quantity of Ingredient that GalaGen is unable to supply is so limited that it would be an excessive financial burden on Wyeth-Ayerst to manufacture, or have manufactured, such limited quantity, the Parties shall meet, after GalaGen is notified by Wyeth-Ayerst of such circumstance, and in good faith seek to reasonably resolve the matter. For purposes of this Section 4.4.1, the provision of such Ingredient to Wyeth-Ayerst by [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] or any permitted subcontractor of GalaGen or [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] shall be deemed for purposes of determining whether Wyeth-Ayerst may exercise its right to manufacture Ingredient hereunder to be the provision of such Ingredient by GalaGen. Notwithstanding any other provision hereof, if GalaGen's failure to supply Ingredient is attributable solely to its inability to [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] otherwise complete the manufacture of Ingredient and its not attributable, in whole or in part, to its inability to [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***], Wyeth-Ayerst shall not [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] and GalaGen shall continue to have the right to be Wyeth-Ayerst's supplier of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] pursuant to the terms and conditions of this 12 Agreement, including, without limitation, the purchase price provisions of Section 6.1 (PROVIDED, HOWEVER, that in such event the calculation of GalaGen's Manufacturing Cost shall be based only on [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***]). Notwithstanding the foregoing, in the event GalaGen is continuing to supply Ingredient to Wyeth-Ayerst as provided herein, Wyeth-Ayerst shall have the right to [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] if, for two successive calendar quarters, GalaGen's inventories of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] fall below the amount of [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] needed to manufacture Wyeth-Ayerst's forecasted needs (as provided in its most recent binding forecasts pursuant to Section 2.3) of Ingredient. 4.4.2 In the event that GalaGen is unable to supply Ingredient as provided above, GalaGen shall be responsible for all costs to qualify Wyeth-Ayerst, or its designated manufacturer, as a manufacturer of the Ingredient. Such costs include, but are not limited to, [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***]. 4.5 RESUMPTION OF MANUFACTURING BY GALAGEN. At such time as GalaGen reasonably demonstrates to Wyeth-Ayerst that it is able to again supply all of Wyeth-Ayerst's requirements on an ongoing basis, Wyeth-Ayerst shall be permitted to continue to manufacture, or have manufactured that amount of Ingredient it had been manufacturing pursuant to Section 4.4 hereof, for such period of time thereafter as is reasonably necessary for Wyeth-Ayerst and/or any of its Affiliates and/or any Third Party manufacturer to fully amortize all expenses that may have been reasonably incurred under such manufacturing program, using generally accepted accounting principles normally used by Wyeth-Ayerst in keeping its own books and records. Thereafter, Wyeth-Ayerst shall purchase its requirements of Ingredient from GalaGen in accordance with the terms of this Agreement, PROVIDED, HOWEVER, that Wyeth-Ayerst shall be permitted to continue manufacturing or purchasing from such Third Party(ies) Ingredient in amounts equal to the greater of (i) the amount of Wyeth's requirements of Ingredient that GalaGen is currently unable to supply or (ii) [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] of Wyeth's requirements of Ingredient that Wyeth-Ayerst has manufactured or has purchased from Third Parties [**CONFIDENTIAL 13 TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***]. 4.6 DISCLOSURE OF GALAGEN KNOW-HOW; TECHNICAL ASSISTANCE. If, pursuant to Sections 4.4 or 4.5 hereof, Wyeth-Ayerst elects to commence manufacturing the Ingredient, either itself or through a Third Party, GalaGen shall promptly disclose to Wyeth-Ayerst all of its Know-How that is necessary to enable Wyeth-Ayerst to so manufacture the Ingredient to the extent permitted hereunder. Additionally, GalaGen shall, at no cost to Wyeth-Ayerst, provide Wyeth-Ayerst with reasonable technical assistance that may be necessary or useful for Wyeth-Ayerst to utilize such Know-How and to commence the manufacture of the Ingredient to the extent permitted hereunder. If GalaGen discloses Know-How to Wyeth-Ayerst for the purpose of enabling Wyeth-Ayerst or its designee to manufacture Ingredient, Wyeth-Ayerst agrees to use such Know-How only for such purpose and such Know-How shall be treated as Confidential Information in accordance with Article 10 hereof. 4.7 QUALITY ASSURANCE. 4.7.1 Prior to the shipment of Ingredient to Wyeth-Ayerst, GalaGen shall test representative samples of each of the lot(s) to be shipped in accordance with the methods of analysis defined in the Specifications. GalaGen shall provide Wyeth-Ayerst with a certificate of analysis for each lot of Ingredient shipped to Wyeth-Ayerst. 4.7.2 Wyeth-Ayerst shall have the right to test Ingredient to verify compliance with Specifications and applicable Regulatory Approvals and GalaGen shall supply Wyeth-Ayerst with its testing procedures. Wyeth-Ayerst may, by written notice provided to GalaGen within [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] of Wyeth-Ayerst's receipt of a shipment of Ingredient, reject all or part of such shipment of Ingredient if, based upon the testing of such Ingredient conducted under this Section 4.7, such Ingredient does not comply with the Specifications. If Wyeth-Ayerst fails to notify GalaGen, within such [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] period, that it is rejecting such Ingredient, Wyeth-Ayerst shall be deemed to have accepted such Ingredient. 4.7.3 If GalaGen, after good faith consultation with Wyeth-Ayerst, disputes any finding by Wyeth-Ayerst that the Ingredient does not comply with the Specifications, samples of such Ingredient shall be forwarded to a Third Party jointly selected by Wyeth-Ayerst and GalaGen for analysis, which analysis shall be performed in compliance with applicable regulatory 14 requirements. The findings of such Third Party regarding whether the Ingredient complies with the Specifications and the applicable Regulatory Approvals shall be binding upon the Parties for purposes of this Section 4.7. The cost of such analysis by such Third Party shall be borne by the Party whose findings differed from those generated by such Third Party. 4.7.4 If, as determined in accordance with this Section 4.7, a shipment of Ingredient does not conform to the Specifications, GalaGen shall replace such shipment free of charge with a substitute shipment which meets such Specifications according to the following time frame: If the Ingredient is in inventory then conforming Ingredient will be shipped so as to arrive as soon as practicable. If the Ingredient is not in inventory, GalaGen will take all reasonable steps to ensure expeditious Manufacture of conforming Ingredient which will be shipped on the next shipping day after completion of Manufacture so as to arrive as soon as possible thereafter. In the event that testing at Wyeth-Ayerst indicates that Ingredient does not conform with Specifications: (i) Wyeth-Ayerst shall immediately notify GalaGen; (ii) Wyeth-Ayerst and GalaGen shall mutually agree on an investigation program to determine the cause of the discrepancy and the outcome of this investigation shall be used to determine disposition of the Batch; (iii) where appropriate, given the timetable for the agreed investigation program, GalaGen shall take all reasonable steps to ensure expeditious Manufacture and shipment of conforming Ingredient; and (iv) shipment of such replacement Ingredient shall take place the next shipping day following completion of analytical work to demonstrate conformance with Specifications. Shipment shall be by the quickest agreed route. At GalaGen's expense and at Wyeth-Ayerst's sole option: (i) the non-conforming shipment shall be returned to GalaGen; or (ii) disposed of by Wyeth-Ayerst, upon final determination in accordance with this Section 4.7 that it does not meet the Specifications. 5.

In the event such [**CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] cannot agree, Wyeth-Ayerst shall have the final authority to decide whether a recall of the Product shall be made. 5.2 RECALL EXPENSES. Wyeth-Ayerst shall bear the expenses of any recall resulting from breach of its obligations hereunder or under the License Agreement, from negligent manufacturing, packaging, storage, shipment, marketing, distribution or sale of the Product by Wyeth-Ayerst or from any manufacturing defect in a Product manufactured or sold by Wyeth-Ayerst which manufacturing defect is not a defect in the Ingredient Manufactured or supplied by or on behalf of GalaGen or its permitted subcontractors hereunder. GalaGen shall bear the expenses of any recall resulting from a breach of its obligations hereunder or under the License Agreement, from negligent Manufacturing, packaging, storage, shipment, marketing, distribution or sale of the Ingredient by GalaGen or from any Manufacturing defect in the Ingredient. The Parties shall equally divide the costs of any recall resulting from a latent defect (for example, side effects of the Ingredient not known by the Parties as of the Effective Date). For the purposes of this Agreement, expenses of recall include, without limitation, the expenses incurred by the affected Party for the investigation, notification, regulatory reporting and/or destruction or return of the recalled Ingredient or Product, the sum paid by Wyeth-Ayerst to GalaGen for the Ingredients recalled, Wyeth-Ayerst's costs relating to the manufacturing, testing, packaging, shipping and supplying the Products recalled. 16 6.

Wyeth-Ayerst, through an independent certified public accountant reasonably acceptable to GalaGen, shall have the right, at its own expense, to access the books and records of GalaGen for the sole purpose of verifying the statements furnished by GalaGen pursuant to Section 6.2. Such access shall be conducted after reasonable prior written notice to GalaGen and during ordinary business hours and shall not be more frequent than twice per calendar year. Wyeth-Ayerst agrees to keep in strict confidence all information learned in the course of such audit, except when it is necessary to reveal such information in order to enforce its rights under this Agreement.
