Within ***** following such Valuation, Novartis may (but shall not be obligated to), by giving written notice to Genentech and Tanox setting forth Novartis’ offer for the Europe Value and the US Value, and the EA/ROW Value (determined as set forth in Sections 18.5(e)-(g) below), elect *****.

If Tanox so elects, then *****.

(e) The Valuations shall be conclusively determined by two internationally recognized investment banking firms, one of which shall be retained and paid by Genentech, and one of which shall be retained and paid by Novartis, provided, however, that, if either Party fails to deliver a notice to the other Party of its selection of an investment banking firm within *****

(h) A Party purchasing the other Party’s interest pursuant to this Section 18.5 shall pay for such interest in cash, by wire transfer of an amount equal to the purchase price for the applicable interest. Any purchase and sale of the Genentech Rights or the Novartis Rights pursuant to this Section 18.5 shall be transferred free and clear of all liens and other encumbrances (except for obligations to another Party set forth in the Tripartite Cooperation Agreement and the Ancillary Agreements) and shall be consummated in a closing (the “Closing”) taking place no later than ***** following:*****.

(i) Upon and subsequent to the Closing, the Parties shall use their respective commercially reasonable efforts to continue to perform obligations not yet completed at such

If Tanox does not elect to purchase the Novartis EA/ROW Interest, then Genentech shall replace Novartis with respect to East Asia and ROW hereunder and under the Ancillary D&L Agreement and Genentech shall assume all of Novartis’ rights and obligations under the Ancillary D&L Agreement.

18.6 Effect of Termination; Survival. Termination or expiration of this Agreement shall not affect or limit the rights or obligations of the Parties (including the obligation to pay amounts due hereunder) that have accrued or were incurred prior to the effective date of such expiration or termination. In addition, the following sections and articles of this Agreement shall survive any expiration or termination of this Agreement: 3 (“Settlement”), 6.6 (“Use of Know-How”), 11 (“Payments”) (with respect to only amounts owing or accrued as of the effective date of termination), 12 (“Dispute Resolution”), 13.3 (“Use of Jointly-Owned Intellectual Property Outside of the Collaboration”), 13.4 (“Licensing of Anti-IgE Specific Patents Outside of the Collaboration”), 15 (“Confidentiality”) (but only for a period of ***** after the effective date of termination or expiration in its entirety, after which time such Article 15 shall have no further force or effect), and 16 (“Limitations on Liability”), this Article 18, and Articles 19 (“Indemnification and Insurance”) (with respect only to events occurring prior to the effective date of termination) and 20 (“Miscellaneous”). All other provisions including the licenses granted herein (except to the extent surviving under Section 18.3), unless expressly provided otherwise herein, shall terminate and be of no further force or effect upon expiration or termination of this Agreement. Expiration of this Agreement in a given territory shall release the Parties from any duties or obligations imposed in this Agreement with respect to such territory, including, for example, restrictions on independent development of Anti-IgE Antibodies or Anti-IgE Products in that territory, except that the foregoing surviving clauses specified above shall remain in effect with respect to such territories. In the event of expiration in a particular territory, however, all terms and conditions of this Agreement shall remain in effect in accordance with their terms with respect to all other, non-expired territories.

In the event any Party objects to any such reference, the applicable document will be modified to such Party’s reasonable satisfaction. If a Party does not deliver its written comments on such documents within ***** of receipt thereof (or such shorter time as may be agreed by the Parties), such Party shall be deemed to have consented to any such references therein.

With respect to any required filing of this Agreement with a Public Authority, the filing Party shall seek confidential treatment of commercially sensitive portions of this Agreement or any Ancillary Agreement and the other Parties shall have the right to review and comment on such an application for confidential treatment prior to its being filed.

20.14 No Partnership or Agency. The Parties hereby acknowledge that while the Parties intend to cooperate as set forth in this Agreement, the Parties are independent contractors and nothing provided in this Agreement or the performance of the Parties under this Agreement is intended or may be deemed to form (or be deemed to constitute in law or in equity) a partnership, agency, joint venture, distributorship, fiduciary, or any other similar relationship between any of the Parties. The Parties are not affiliated and no Party has any right or authority to bind any other Party in any way.

20.15 Further Assurances.

TRANSITIONAL ARRANGEMENTS

Notwithstanding anything in this Schedule D, the Parties rights and obligations with respect to the assumption of Manufacturing activities and the transfer of Manufacturing technology shall not apply if and for so long as the Terminating Party(ies) or Technology Party(ies) elect to continue to Manufacture and supply Active Products hereunder; provided, however, (1) that the foregoing shall not limit any licenses granted below with respect to any Anti-IgE Patents for any Anti-IgE Product which is not an Active Product Manufactured by the Terminating Party(ies); and (2) that the Terminating Party shall be obliged to continued to fulfill all obligations to the applicable Public Authorities with respect to such continuing Manufacture.

PART 1 – TERMINATION AS TO BOTH NOVARTIS AND GENENTECH

In the event that both Novartis and Genentech terminate this Agreement as set forth in Section 18.3(c), the Terminating Party(ies) shall provide all cooperation and assistance reasonably requested by Tanox to enable Tanox (or its designee) to assume with as little disruption as reasonably possible, the continued Manufacture, Development and Commercialization of the Anti-IgE Products then being Commercialized or Developed hereunder (the “Active Products”), if Tanox so chooses to pursue such continued Manufacture, Development and/or Commercialization. Such cooperation and assistance shall be provided in a prompt and timely manner (having regard to the nature of the cooperation or assistance requested) and shall include, without limitation, the following:

(i) License Grants and Intellectual Property.

(A) Subject to Tanox’s compliance with the applicable surviving terms and conditions of this Agreement as set forth in this Part 1 of Schedule D and in Section 18.4(d) and Section 18.6, Tanox shall have an exclusive (as to Anti-IgE Antibodies and Anti-IgE Products), Worldwide license (which shall include the right to grant sublicenses) from the Terminating Party(ies) to develop, make, have made (in the case of making and having made, subject to paragraph (vii) below), use, import, offer to sell and sell Anti-IgE Products and Anti-IgE Antibodies under the Anti-IgE Patents, Company Information and Know-How Controlled by the Terminating Party(ies) existing at the effective date of termination, which Anti-IgE Patents, Company Information and Know-How are reasonably required, or to the extent they are used by the Terminating Party(ies) or its (or their) licensee or sublicensee as at the effective date of termination, to Develop, make, have made, use, import, offer to sell and sell Active Products. The foregoing license:

(1) shall not extend to patents, patent applications, know-how, and materials not in existence as of the date of termination, but shall include patents claiming priority back to any patents or patent applications covering Active Products as of the effective date of termination; and

(2) shall extend to patents, patent applications, know-how, and materials only to the extent the Terminating Party(ies) has the right to grant such

SCHEDULE D

right without incurring any royalty or other payment obligation to any Third Party (or significant diminution of the Terminating Party(ies) rights if a direct license is available) with respect thereto, unless Tanox agrees to fully reimburse such royalty or other payment obligation in which case such Third Party rights shall be included in the license grant to the extent of the Terminating Party(ies) rights to do so; and

*****

C. Notwithstanding the foregoing or anything to the contrary in this Agreement, Tanox shall not have any right or license under Genentech’s intellectual property rights to Manufacture Anti-IgE Antibodies or Anti-IgE Products in East Asia or Rest of World, except in any country in which such Anti-IgE Product is then being Manufactured, or with Genentech’s express approval.

This financial appendix (the “Financial Appendix”) is Schedule A attached to and incorporated into the Tripartite Cooperation Agreement (the “Agreement”) dated as of February 25, 2004 by and among Novartis Pharma AG (“Novartis”), Genentech, Inc. (“Genentech”) and Tanox, Inc. (“Tanox”) (each also singularly referred to herein as a “Party” and collectively as the “Parties”).

This Financial Appendix covers the financial planning, accounting practices and procedures to be followed in determining the “Net Sales” and the “Net Profit” or “Net Loss” (as defined below) and related payment of royalties and sharing of revenue and costs and expenses in the U.S. and Europe pursuant to the Agreement. For such purpose, this Financial Appendix sets out, among other things, the principles of reporting among the Parties the actual results and budgeted plans, forecasts and long range plans of “GenNov” (as defined below), the frequency of reporting, the use of a single “Functional Currency” (as defined below) for determining and reporting payments to the Parties, auditing of accounts and other matters. The consolidated accounting construct consisting of certain Genentech and Novartis operations under the Agreement will be referred to as “GenNov”. It should be noted that “GenNov” is not a legal entity and has been defined for identification purposes only.

The functionality of “GenNov” relates only to the “United States” and “Europe” (as defined in the Agreement), and largely to the operations of Genentech and Novartis. Thus, references in this Financial Appendix to a “GenNov Party” or “GenNov Parties” shall be construed to mean Genentech and/or Novartis (and its Affiliates), as the case may be (but not Tanox), for purposes of this Financial Appendix and the Agreement, including the application of the financial definitions herein. “GenNov” is a virtual account and not a separate auditable entity.

This Financial Appendix also provides agreed upon definitions of financial terms applicable to the Parties for purposes of the Agreement, and, subject to the terms of the Agreement, sets forth roles and responsibilities of the Finance Sub-Committee. All capitalized terms used herein without definition shall have the meanings ascribed thereto in the Agreement, unless otherwise expressly provided herein. In the event of a conflict between the terms and provisions of this Financial Appendix and the Agreement, the terms and provisions of the Agreement shall govern.

i

The contents of this Financial Appendix, and all activities hereunder, are to be governed by the terms and conditions of the Agreement, including the confidentiality provisions set forth therein.

1. Principles of Reporting

For purposes of the sharing of costs and sharing of “Net Profit” or “Net Loss” (as the case may be) among the Parties as provided under the Agreement and this Financial Appendix, the presentation of results of operations of the GenNov Parties for each of the United States and Europe will be based on each GenNov Party’s respective financial information for each territory for the applicable period in the reporting format depicted as follows *****:

For the United States		Novartis		Genentech		Total
Gross Sales (U.S.)
less *****
=            Net Sales (U.S.)
less *****
=            Gross Profit (U.S.)
less *****
*****
=            Net Profit (U.S.) or Net Loss (U.S.) for purpose of GenNov profit share;

and

For Novartis and Tanox only:

Novartis’ share of Net Profit (U.S.) in accordance with the Agreement and this Financial Appendix;

            less *****.

=         Net Profit (TANOX) for purpose of calculating the Tanox Profit Share

For Europe		Novartis		Genentech		Total
Gross Sales (EUR)
less *****
=            Net Sales (EUR)
less *****

It is the intention of Genentech, Novartis and Tanox that the interpretation of these definitions and other matters under this Financial Appendix will be: (a) consistent with the U.S. generally accepted accounting principles (“GAAP”) consistently applied for Genentech; and (b) international accounting standards as consistently applied (“IAS”) for Novartis. The Finance Sub-Committee shall ensure consistency in accounting treatment between GAAP and IAS, where possible.

If necessary a Party will make the appropriate adjustments to the formatting of financial information it supplies under the Agreement to conform to the format of reporting results of operations for purposes of GenNov as set forth in this Financial Appendix.
