Genentech shall bear all costs related to the commercialization of the Licensed Products by Genentech in the Territory, except for US Costs if TolerRx exercises the US Profit/Loss Sharing Option set forth in Section 6.5. 4.2. DEVELOPMENT OR MARKETING WITH INDEPENDENT PRODUCTS. (a) Without limiting Genentech's rights, if TolerRx reasonably believes that marketing a Licensed Product in conjunction with an Independent Product will maximize the profits for such Licensed Product, at TolerRx's written request, Genentech agrees to use Commercially Reasonable and Diligent Efforts to negotiate (for a period of sixty (60) days) in good faith an arrangement with the Third Party that owns or Controls such Independent Product whereby Licensed Product will be marketed in conjunction with the Independent Product, provided that Genentech shall be obligated to do so only if it determines in its sole discretion that (a) such development or marketing would not adversely affect any Licensed Product, other Genentech product, or Genentech; (b) such development or marketing would be desirable and financially profitable and would significantly increase the Net Sales of such Licensed Product; and (c) such Third Party is reasonably acceptable to Genentech. This Section 4.2 shall apply Execution Copy - 15 - <Page> GENENTECH CONFIDENTIAL only after Licensed Product for Phase III Clinical Trials manufactured by Genentech or its third party sublicensees on Genentech's behalf is available (and Genentech shall not have any obligations under this Section 4.2 (a) to so negotiate until such time). "INDEPENDENT PRODUCT" means a Third Party's pharmaceutical, stand-alone product that (A) has received Regulatory Approval in the United States; (B) has been fully developed and commercialized as a stand-alone product by such Third Party, and Genentech is not involved in and has no rights or obligations with respect to current or future involvement in researching, developing or commercializing or any other aspect of such product; and (C) Genentech determines would be desirable to market or develop with the Licensed Product. (b) If Genentech executes an agreement with such Third Party for marketing or developing the Licensed Product in conjunction with an Independent Product, and if (and only if) Genentech is not obligated to provide any consideration to such Third Party, then during the Term, Genentech shall share (in accordance with the percentages below) with TolerRx the portion of upfront, milestone, or royalty payments, if any, actually received by Genentech from such Third Party that would constitute Independent Product Profit for Genentech. Such Independent Product Profit shall be shared between the Parties: with TolerRx receiving [***] of such amounts and Genentech receiving [***] of such amounts. "INDEPENDENT PRODUCT PROFIT" means the upfront, milestone, royalty payments received by Genentech from such Third Party and less Reimbursements. "REIMBURSEMENTS" means reimbursements of all fully burdened costs incurred by Genentech related to developing, manufacturing, distribution, marketing, and/or sales of such Licensed Product in conjunction with such Independent Product. Independent Product Profit shall only consist of such payments received by Genentech from such Third Party that are solely attributable to Genentech's marketing and development activities (and not attributable to any other action or inaction of Genentech or other reasons) for the Licensed Product in conjunction with such Independent Product. All payments received by Genentech from such Third Party relating to any of Genentech's intellectual property or any other Genentech activity shall be excluded from Independent Product Profit. ARTICLE 5 LICENSE 5.1. GRANT OF THE RIGHTS TO GENENTECH. Subject to the terms and conditions of this Agreement, TolerRx hereby grants to Genentech an exclusive (even as to TolerRx), sublicensable license under TolerRx Patent Rights, TolerRx Know-how and TolerRx's joint ownership rights in Joint Patents (as defined in Section 7 herein), to make (and have made), use, sell, offer for sale and/or import Licensed Product, within the Field in the Territory. 5.2.

DEVELOPMENT MILESTONES. (a) PAYMENTS FOR THE FIRST OCCURRENCE OF MILESTONES. As consideration to TolerRx for the licenses and other rights granted to Genentech under this Agreement, during the Term, Genentech shall pay to TolerRx the following milestone payments upon the first occurrence of each event set forth below with respect to only the first Licensed Product for which the milestone is achieved by or on behalf of Genentech. For purposes of clarification, each milestone in this Section 6.2(a) shall be payable only once. Such milestone shall be payable within forty-five (45) days of when the first Licensed Product that is manufactured by or on behalf of Genentech fully satisfies such milestone requirement. For the purposes of this Section 6.2 and 6.5 only, any reference to achieving a milestone or manufacturing "by or on behalf of Genentech" or "by or for Genentech" refers only to achievement of such milestone or manufacturing by Genentech or by Genentech's third party sublicensees on Genentech's behalf, and excludes TolerRx unless otherwise agreed to expressly in writing by the parties. Execution Copy - 18 - <Page> GENENTECH CONFIDENTIAL Milestone Payment --------- ------- (i) Genentech's portfolio planning committee (or future equivalent)'s decision to place Licensed Product into formal development for the first time $[***] (ii) First filing of IND by Genentech for Licensed Product manufactured by or for Genentech $[***] (iii) Administration of Licensed Product manufactured by or for Genentech to first patient in first Phase I Clinical Trial in the United States $[***] (iv) Administration of Licensed Product manufactured by or for Genentech to first patient in first Phase II Clinical Trial in the United States $[***] (v) Administration of Licensed Product to first patient in first Phase III Clinical Trial in the United States $[***] (vi) Filing of first BLA for Licensed Product in United States $[***] (vii) First Regulatory Approval for Licensed Product in United States $[***] (viii) Filing of first MAA with the EMEA for Licensed Product $[***] (ix) First Regulatory Approval by EMEA for Licensed Product $[***] (b) ADDITIONAL MILESTONES FOR DIFFERENT INDICATIONS. This Section 6.2(b) applies only after the corresponding milestone has been paid under Section 6.2(a). As consideration to TolerRx for the licenses and other rights granted to Genentech under this Agreement, during the Term, Genentech shall pay to TolerRx the following milestone payments upon the first occurrence of each event set forth below with respect to each of two Different Indications for which the milestone is achieved by or on behalf of Genentech. "Different Indication" means an Indication that is different from any other Indication for which the * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 19 - <Page> GENENTECH CONFIDENTIAL corresponding milestone was paid under Section 6.2(a) or 6.2(b). Each milestone in this Section 6.2(b) shall be payable only once for each Different Indication, up to a maximum of two Different Indications. Such milestone shall be payable within forty-five (45) days of when such Indication for a Licensed Product that is manufactured by or on behalf of Genentech fully satisfies such milestone requirement. For avoidance of doubt, each milestone in this Section 6.2(b) shall be paid at most twice only: (R) the first such milestone payment for the first Different Indication to satisfy that milestone, and (S) the second payment for a second Different Indication to satisfy that milestone. Genentech shall not make any payments under Section 6.2(b) with regard to any other Indications or Licensed Products. Milestone Payment --------- ------- (i) Genentech's portfolio planning committee (or $[***] future equivalent)'s decision to place Licensed Product into formal development for first or second Different Indication for the first time (ii) Administration of Licensed Product to first patient in first Phase III Clinical Trial in the United States for first or second Different Indication $[***] (iii) Filing of first BLA for Licensed Product for first or second Different Indication in United States $[***] (iv) First Regulatory Approval for Licensed Product for first or second Different Indication in United States $[***] (v) Filing of first MAA with the EMEA for Licensed Product for first or second Indication in European Union $[***] (vi) First Regulatory Approval by EMEA for Licensed Product for first or second Different Indication in European Union $[***] (c) EXAMPLE. The milestone payments above shall be calculated in accordance with the following example. There are Licensed Product(s) for three Different Indications. Licensed Product for one Indication ("LP1") is placed into development by * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 20 - <Page> GENENTECH CONFIDENTIAL Genentech's portfolio planning committee, continues to develop, and fails to proceed beyond Phase III Clinical Trials. The Licensed Product for a second Indication ("LP2") is placed into development by Genentech's portfolio planning committee, continues to develop, and completes all possible milestones, including receiving Regulatory Approval in the United States and from the EMEA. The Licensed Product for a third Indication ("LP3") is placed into development by Genentech's portfolio planning committee, continues to develop, receives Regulatory Approval in the United States, and files MAA with the EMEA but fails to receive Regulatory Approval by EMEA. For LP1, the applicable milestone payments would be Section 6.2(a)(i) through 6.2(a)(v). For LP2, the applicable milestone payments would be Section 6.2(b)(i), 6.2(b)(ii) and 6.2(a)(vi) through 6.2(a)(ix). For LP3, the applicable milestone payments would be Section 6.2(b)(i) through 6.2(b)(v). In this example, no further payments shall be made under Section 6.2(a) and 6.2(b)(i) and 6.2(b)(ii). 6.3. ROYALTIES. The royalties set forth in this Section 6.3 shall apply to Net Sales in each country within the Territory, unless TolerRx properly exercises and participates in the US Profit/Loss Sharing Option, in which case (P) the royalties set forth in this Section 6.3 shall apply only to Net Sales in countries in the Territory other than the United States and (Q) Section 6.5 applies to the United States. Subject to the foregoing, royalties payable by Genentech under this Section 6.3 shall be determined and payable on a country-by-country and Licensed Product-by-Licensed Product basis as follows (depending on the type of Licensed Product sold in such country): (A) with respect to such Licensed Product that, but for the licenses granted herein, would infringe a Valid Claim in such country, the royalties as set forth in Section 6.3(a); or (B) with respect to such Licensed Product that would not infringe a Valid Claim in such country, but (X) relies on or incorporates TolerRx Know-how, including but not limited to, Antibodies provided by TolerRx to Genentech pursuant to this Agreement or (Y) was developed pursuant to the Development Plan, the royalties set forth in Section 6.3(b). All such royalties shall be further reduced by one or more of the following Sections, to the extent applicable: Sections 6.3(c) and 6.4. For clarity, no royalties for a Licensed Product in a country shall be owed by Genentech under Sections 6.3 or 6.4 until the date of Commercial Introduction of such Licensed Product in such country. All references in this Agreement to "royalties under Sections 6.3 and 6.4" "royalties set forth in Sections 6.3 and 6.4" or the like shall mean royalties set forth in Sections 6.3, reduced by Section 6.4 if applicable. (a) ROYALTIES OWED BY GENENTECH FOR LICENSED PRODUCTS COVERED BY VALID CLAIM. As consideration to TolerRx for the licenses and other rights granted to Genentech under this Agreement, during the Term, Genentech shall make royalty payments to TolerRx (for each Licensed Product sold in the country(ies) where the sale of such Licensed Product, but for the licenses granted herein, would infringe a Valid Claim) as follows and such payments shall be reduced by Sections 6.3(c), and/or 6.4 to the extent applicable. (i) Genentech shall pay a royalty of [***] for the portion of Patented Product Aggregate Annual Worldwide Net Sales that is less than or equal to $[***]. * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 21 - <Page> GENENTECH CONFIDENTIAL (ii) Genentech shall pay a royalty of [***] for the portion of Patented Product Aggregate Annual Worldwide Net Sales that is greater than $[***] and less than or equal to $[***]. (iii) Genentech shall pay a royalty of [***] for the portion of Patented Product Aggregate Annual Worldwide Net Sales that is greater than $[***] and less than or equal to $[***]. (iv) Genentech shall pay a royalty of [***] for the portion of Patented Product Aggregate Annual Worldwide Net Sales that is greater than $[***]. "Patented Product Aggregate Annual Worldwide Net Sales" means aggregating the Net Sales amounts (occurring in the applicable calendar year) of all such Licensed Products the sales of which, but for the licenses granted herein, would infringe a Valid Claim in the country where such sales occur. Patented Product Aggregate Annual Worldwide Net Sales consists of aggregating such Net Sales of only such Licensed Products of the same type as described in Section 6.3(d) below. For example, if Patented Product Aggregate Annual Worldwide Net Sales of Type A Licensed Products (as defined in Section 6.3(d) below) in the Territory totaled $[***], then the applicable royalties that Genentech would pay is ([***] X $[***]) + ([***] X $[***]) + ([***] X $[***]) + ([***] X [***]) = $[***]. (b) ROYALTIES OWED BY GENENTECH FOR LICENSED PRODUCTS COVERED BY TOLERRX KNOW-HOW. During the Royalty Term, with respect to Licensed Product sold in the country(ies) where the sale of such Licensed Product, but for the licenses granted herein, would not infringe a Valid Claim, but such Licensed Product in the country where sold (A) relies on or incorporates TolerRx Know-how, including but not limited to, Antibodies provided by TolerRx to Genentech pursuant to this Agreement, or (B) was developed pursuant to the Development Plan, Genentech shall make royalty payments to TolerRx for such Licensed Products as follows and such payments shall be reduced by Sections 6.3(c), and/or 6.4 to the extent applicable. (i) Genentech shall pay a royalty of [***] for the portion of Non-Patented Product Aggregate Annual Worldwide Net Sales that is less than or equal to $[***]. (ii) Genentech shall pay a royalty of [***]for the portion of Non-Patented Product Aggregate Annual Worldwide Net Sales that is greater than $[***] and less than or equal to $[***]. (iii) Genentech shall pay a royalty of [***] for the portion of Non-Patented Product Aggregate Annual Worldwide Net Sales that is greater than $[***] and less than or equal to $[***]. * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 22 - <Page> GENENTECH CONFIDENTIAL (iv) Genentech shall pay a royalty of [***] for the portion of Non-Patented Product Aggregate Annual Worldwide Net Sales that is greater than $[***]. "Non-Patented Product Aggregate Annual Worldwide Net Sales" means aggregating the Net Sales amounts (occurring in the applicable calendar year) of all such Licensed Products the sales of which, but for the licenses granted herein, would not infringe a Valid Claim in the country where such sales occur but which Licensed Products in the country where such sales occur (A) rely on or incorporate TolerRx Know-how, including but not limited to, Antibodies provided by TolerRx to Genentech pursuant to this Agreement, or (B) were developed pursuant to the Development Plan. Non-Patented Product Aggregate Annual Worldwide Net Sales consists of aggregating such Net Sales of only such Licensed Products of the same type as described in Section 6.3(d) below. (c) ROYALTIES OWED BY GENENTECH IF ANOTHER ANTI-CD4 PRODUCT EXISTS. Genentech's royalty payment obligations as set forth in Sections 6.3(a) or 6.3(b) above shall not apply in those countries for a Licensed Product during the period that any of the following is true in such countries: (A) Another Anti-CD4 Product has received Regulatory Approval for an Indication that is the same as an Indication for which the Licensed Product has received Regulatory Approval or (B) the total volume of Other Anti-CD4 Products (commercialized, used or sold for an Indication that is the same as any Indication for which the Licensed Product has received Regulatory Approval) equals [***] or more of the total volume of products containing an Antibody or Antibodies or any formulation thereof commercialized, used, or sold for such Indication. Instead, Genentech shall only pay a royalty of (i) during the Term, with respect to those Licensed Products described in Section 6.3(a), [***] for annual Net Sales of such Licensed Products in such countries where sold; or (B) during the Royalty Term, with respect to those Licensed Products described in Section 6.3(b), [***] on all Net Sales amounts of such Licensed Product in such countries where sold (except that such royalty payments shall not be reduced by this Section 6.3(c) below the Minimum Royalty Rate). For the purpose of this Agreement, "ANOTHER ANTI-CD4 PRODUCT" means any third party product containing an Antibody or Antibodies or any formulation thereof, including, without limitation, any lyophilized liquid, sustained release or aerosolized formulation. "OTHER ANTI-CD4 PRODUCTS" means all of the third party products in such countries that are Another Anti-CD4 Product. (d) CALCULATIONS AND EXAMPLE. The royalties in Section 6.3 and 6.4 herein shall be calculated on a country-by-country and Licensed Product-by-Licensed Product basis, by aggregating Net Sales for all applicable countries with Licensed Products of the same type, as in the following example: In France and Germany, only Licensed Products described in Section 6.3(a), but to which Sections 6.3(c) and 6.4 do not apply ("Type A Licensed Products") are sold. In Spain and Portugal, only Licensed Products described in Section 6.3(a) to which Section 6.3(c) does apply (but to which Section 6.4 does not apply, because no amounts described in Section 6.4 are paid to a third party) ("Type B Licensed Products") are sold. In the above example, the Net Sales for France and Germany for Type A Licensed Products shall be aggregated and the applicable royalty for the portions of Net Sales of such Licensed Products * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 23 - <Page> GENENTECH CONFIDENTIAL shall be as set forth in Section 6.3(a). The Net Sales for Spain and Portugal for Type B Licensed Products shall be aggregated and the applicable royalty for the portions of Net Sales of such Licensed Products shall be as set forth in Section 6.3(c). For clarity, the Net Sales amounts for countries with Licensed Product of one type shall not be aggregated with Net Sales amounts for countries with Licensed Product of a different type. In the above example, in calculating royalties, the Net Sales amounts of Type A Licensed Products shall not be aggregated with the Net Sales amounts of Type B Licensed Products. 6.4. THIRD PARTY ROYALTIES. On a country-by-country basis and Licensed Product-by Licensed Product basis, the royalties otherwise due and payable by Genentech to TolerRx hereunder, with respect to a Licensed Product in a country, shall be reduced by an amount equal to [***] of the amounts Genentech or its third party sublicensee(s) pays to any third party with respect to the development, manufacture, import or export, use, offer for sale or sale with respect to such Licensed Product in such country; PROVIDED, HOWEVER, that in no event shall the royalty payments due and payable to TolerRx with respect to such Licensed Product in such country be reduced by this Section 6.4 by more than [***] of Net Sales with respect to such Licensed Product in such country and the royalty payments shall not be reduced by this Section 6.4 below the Minimum Royalty Rate. For example, if the Net Sales amount for a Licensed Product described in Section 6.3(a) (assuming that no other reductions in Section 6.3(c) apply) for a country is $[***] and if Genentech owes royalties to a third party of [***] of Net Sales, then Genentech may reduce such royalty owed to TolerRx by [***] of such Net Sales, so that the resulting royalty rate is lowered in the foregoing example from [***] to [***] (in other words, lowered by $[***]). If the royalty rate to the third party is [***], the royalty reduction is still $[***]. 6.5. OPTION TO SHARE OPERATING PROFITS OR LOSSES IN UNITED STATES. (a) Subject to the terms and conditions of this Agreement, in lieu of the royalties set forth in Sections 6.3 and 6.4 for Net Sales in the United States, on a Licensed Product-by-Licensed Product basis, subject to Section 6.5(b), TolerRx shall have an option to share in Operating Profits or Losses (as defined in Exhibit A) from sales of Licensed Products in the United States, PROVIDED THAT, TolerRx: (A) makes the US Cost Sharing Payments within the time period set forth below and (B) during the time period set forth below, continues to make the applicable balancing payments, if any, relating to sharing Operating Loss, on a timely basis in accordance with Section 6.5(c) below and Exhibit A attached hereto (including but not limited to Section A.4 of Exhibit A) ("US Profit/Loss Sharing Option"). "US COST SHARING PAYMENTS" means the portion of US Costs owed by TolerRx to Genentech under this Agreement as set forth in Exhibit A for Development Costs (as defined in Exhibit A) to the date of the Phase II Go Decision Notice, which amount shall be identified in a written notice to TolerRx. Upon Genentech providing written notice of its decision to commence the first Phase II Clinical Trial for the first Indication of the first such Licensed Product manufactured by or on behalf of Genentech by third parties and providing TolerRx written notice of the U.S. Cost Sharing Payments ("Phase II Go Decision Notice"), TolerRx shall have (X) thirty (30) days from the date * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 24 - <Page> GENENTECH CONFIDENTIAL of such Phase II Go Decision Notice to exercise the US Profit/Loss Sharing Option by delivering proper written notice to Genentech and (Y) forty-five (45) days from the date of such Phase II Go Decision Notice to make such US Cost Sharing Payments. (b) On a Licensed Product-by-Licensed Product basis, TolerRx shall share in Operating Losses (as defined in Exhibit A), if any, commencing from the date TolerRx exercises such US Profit/Loss Sharing Option and ending on the date when Genentech terminates sales of such Licensed Product in the United States, subject to earlier termination as set forth in Section 6.5(c) below. Subject to the last two sentences of this Section 6.5(b), TolerRx shall share in Operating Profits (as defined in Exhibit A), if any, commencing from the first date that an Operating Profit exists (and TolerRx shall not have such right to share in Operating Profits until such date) and ending on the date when Genentech terminates sales of such Licensed Product in the United States, subject to earlier termination as set forth in Section 6.5(c) below. For the avoidance of doubt, the Operating Losses shall include costs incurred from the date of filing of the first IND by Genentech (including but not limited to the FTE Cost(s) and filing fees for filing such IND). Without limiting any of Genentech's rights or remedies, TolerRx shall have the right to receive its share of Operating Profits as set forth in Exhibit A and this Section 6.5 only after Genentech has recouped all of TolerRx's share of the Operating Losses. At Genentech's election in its sole discretion, Genentech may recoup all of such Operating Losses either through (P) direct payment by TolerRx of all applicable balancing payment amounts in accordance with Exhibit A and this Section 6.5 or (Q) deducting all of such Operating Losses from TolerRx's share of Operating Profits. (c) Genentech shall only be obligated to pay the royalties set forth in Section 6.3 and 6.4, if any, and shall not be obligated at any time to share Operating Profits or Losses under Exhibit A, if TolerRx: (A) fails to make US Cost Sharing Payments within forty-five (45) days from the date of such Phase II Go Decision Notice or (B) fails to notify Genentech of its exercise of the US Profit/Loss Sharing Option within thirty (30) days from the date of the Phase II Go Decision Notice for the applicable Licensed Product. If TolerRx fails to make the applicable balancing payments relating to sharing Operating Profit or Loss, if any, on a timely basis in accordance with Exhibit A, and does not do so within thirty (30) days of written notice of such failure from Genentech, effective as of the beginning of the calendar quarter in which such failure to pay by TolerRx occurs then Genentech shall not be obligated to share Operating Profits or Losses under Exhibit A and Genentech shall only be obligated to pay the royalties set forth in Section 6.3 and 6.4, if any. Nothing herein relieves TolerRx of its obligation to make such delinquent payment. (d) If TolerRx has exercised and continues to participate in the US Profit/Loss Sharing Option in accordance with Section 6.5 and Exhibit A, upon completion of Phase III Clinical Trial for a Licensed Product, Genentech shall prepare and provide to the JSC a copy of Marketing Plan for such Licensed Product. Thereafter, for each calendar year, at least three months prior to the beginning thereof, Genentech shall provide the JSC an updated copy of such Marketing Plan. The JSC may review such Marketing Plan but Genentech has sole Execution Copy - 25 - <Page> GENENTECH CONFIDENTIAL authority regarding the content of such Marketing Plan and may make modifications thereto, from time to time. Such Marketing Plan will include a budget. 6.6. PAYMENT OF ROYALTIES AND OTHER AMOUNTS. (a) MODE OF PAYMENTS. Net Sales described in Sections 6.3, 6.4, 9.5(c)(iii) (to the extent applicable) will be calculated on a calendar quarter basis. For purposes of determining when a sale of any Licensed Product occurs under this Agreement, the sale shall be deemed to occur on the date the Licensed Product is shipped. The obligation to pay royalties under this Agreement shall be imposed only once with respect to the same unit of Licensed Product, regardless of the number of patents within TolerRx Patent Rights pertaining thereto and regardless of whether such unit of Licensed Product is based on one or more than one of the following: TolerRx Know-how, patents within TolerRx Patent Rights, and/or was developed pursuant to the Development Plan. After the date of Commercial Introduction of each Licensed Product, all royalty payments for such Licensed Product shall be made within sixty (60) days after the end of each calendar quarter in which such sales were deemed to occur. All payments hereunder shall be made free and clear of any taxes, duties, levies, fees or charges, except for withholding taxes (to the extent applicable). Genentech shall make any applicable withholding payments due on behalf of TolerRx and shall promptly provide TolerRx with written documentation of any such payment sufficient to satisfy the requirements of the United States Internal Revenue Service related to an application by TolerRx for a foreign tax credit for such payment. All payments hereunder due to TolerRx shall be made in U.S. Dollars by bank wire transfer to: [***], except as provided below. TolerRx may modify such bank wire transfer information upon providing written notice to Genentech. (b) FOREIGN CURRENCY CONVERSION. For the purpose of calculating royalty payments to TolerRx under Sections 6.3 and 6.4 above and calculating royalty payments to Genentech under Section 9.5(c)(iii) (to the extent applicable), if Licensed Products are sold in a currency other than U.S. dollars, such non-U.S. currencies shall be converted to U.S. dollars at the daily Reuters exchange rate for the last business day of such calendar quarter in which the relevant financial transactions are recorded. (c) RESTRICTIONS ON PAYMENT. If by law, regulations or fiscal policy of a particular country in the Territory, remittance of royalties in U.S. Dollars is restricted or forbidden, written notice thereof will promptly be given to TolerRx, and payment of the royalty shall be made by the deposit thereof in local currency to the credit of TolerRx in a recognized banking institution in such country selected by Genentech and reasonably acceptable to TolerRx. When, in any country in the Territory, the law or regulations prohibit both the transmittal and deposit of royalties on sales in such country, royalty payments shall be suspended for as long as such prohibition is in effect and as soon as such prohibition ceases to be in effect, all royalties that Genentech would have been under an obligation to transmit or deposit but for the prohibition shall forthwith be deposited or transmitted to the extent allowable. * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 26 - <Page> GENENTECH CONFIDENTIAL (d) REPORTS. Each royalty payment shall be accompanied by a report, Licensed Product-by- Licensed Product and country-by-country, of the amount of Gross Sales, the calculation of Net Sales and the units of Licensed Product sold during such quarter, the amount of royalties due on such Net Sales, and the conversion rates used in converting to United States Dollars. 6.7. RECORDS. Genentech shall keep complete and accurate records pertaining to the sale of Licensed Products in the Territory and covering all transactions from which Net Sales and payments to be made to TolerRx and amounts to be charged to TolerRx are derived for a period of three calendar years after the year in which such sales occur and such costs are incurred. TolerRx shall keep complete and accurate records pertaining to the following, if applicable: TolerRx MSL Costs, costs related to Sections 3.4(b) and 3.4(c) herein, TolerRx Development Plan Work Costs, and, if Section 9.5(c)(iii) applies, the sale of Licensed Products in the Territory and covering all transactions from which Net Sales and payments to be made to Genentech under Section 9.5(c)(iii) are derived for a period of three calendar years after the year in which such sales occur and such costs are incurred. 6.8. AUDIT. At the request and expense (except as provided below) of TolerRx, not more than once per year, Genentech shall permit an independent, certified public accountant appointed by TolerRx and reasonably acceptable to Genentech, at reasonable times during normal business hours and upon thirty (30) days' notice, to examine those financial records of Genentech directly used in Genentech's calculations of (A) royalties under Sections 6.3 and 6.4 herein for a period of three years after such royalties have accrued, to determine or verify the appropriate royalties owed to TolerRx, and (B) Direct Costs and Net Sales (only if TolerRx has exercised and continues to participate in the US Profit/Loss Sharing Option in accordance with Section 6.5 and Exhibit A), to determine or verify the Direct Costs and Net Sales. The term "royalties" as referred to in this Section 6.8 only, shall only refer to the royalties set forth in Sections 6.3 and 6.4 of this Agreement. "Direct Costs" means (A) direct costs of labor and materials related to Development Costs, Marketing Costs, and Sales Costs (as defined in Exhibit A) and (B) Third Party Royalty Expense (as defined in Exhibit A). For clarity, Direct Costs excludes indirect costs and Allocable Overhead. For the avoidance of doubt, TolerRx shall not have such accountant examine financial records related to other items in Exhibit A (ie. US Costs other than Direct Costs), and shall only have the right to confirm that Genentech's costing and accounting methodology related to such other items is consistent with GAAP. Said accountant shall not disclose to TolerRx any information other than information necessary to verify such royalties or Direct Costs and Net Sales (if applicable). Subject to the foregoing, results of any such examination shall be made available to both Parties. If, as a result of such inspection of the books and records of Genentech to verify (X) royalties or (Y) Direct Costs and Net Sales (if applicable), it is shown that Genentech's royalty payments under this Agreement or balancing payments under Sections 6.5 and Exhibit A were less than the amount which should have been paid to TolerRx, then Genentech shall make all payments required to be made to eliminate any discrepancy revealed by said inspection within sixty (60) days after TolerRx's demand therefor. Furthermore, if the aggregate of royalties or balancing payments under Sections 6.5 and Exhibit A Execution Copy - 27 - <Page> GENENTECH CONFIDENTIAL (if applicable) were less than the amount which should have been paid to TolerRx by an amount in excess of five percent (5%) of the respective payments actually made during the period in question, Genentech shall also reimburse TolerRx for the cost of such inspection. As a condition to such examination, such independent public accountant shall execute a written agreement, reasonably satisfactory in form and substance to Genentech, to maintain in confidence all information obtained during the course of any such examination except for disclosure to TolerRx as necessary for the above purpose. A Dispute (as defined in Section 12.13) on the conclusions of such audit by such public accountant shall be resolved in accordance with Section 12.13. ARTICLE 7 PATENT RIGHTS; TRADEMARKS 7.1.

(b) ENFORCEMENT ACTIONS. (1) JOINT PATENTS. Genentech shall have the first right (but not the obligation) to take the appropriate steps to remove the Patent Infringement or alleged Patent Infringement of Joint Patents, including, without limitation, by initiation, prosecution and control, at its own expense (subject to Section 6.5 and Exhibit A regarding TolerRx's US Profit/Loss Sharing Option) of any suit, proceeding or other legal action by counsel of its own choice. TolerRx shall have the right, at its own expense, to be represented in any such action by counsel of its own choice. TolerRx agrees to cooperate reasonably in any such action Genentech Execution Copy - 30 - <Page> GENENTECH CONFIDENTIAL initiates or wishes to initiate hereunder, including, without limitation, supplying essential documentary evidence and making essential witnesses then in TolerRx's employment available. As part of such cooperation, Genentech may join or include TolerRx as a party, if the need arises. Genentech shall notify TolerRx of its decision to exercise its right to enforce Joint Patents not later than ninety (90) days following its discovery or receipt of notice of the alleged Patent Infringement. TolerRx has no right to bring any such action or proceeding relating to Genentech Patents. With respect to Joint Patents, if (i) Genentech notifies TolerRx that Genentech elects not to bring a suit, action or proceeding to enforce the Joint Patents in accordance with this Section 7.7(b)(1); or (ii) Genentech has not provided TolerRx with evidence of bona fide negotiations with the alleged infringer, then TolerRx shall have the right (but not the obligation), at is own expense, to bring any such suit, action or proceeding relating to Joint Patents by counsel of its own choice, and Genentech shall have the right, at its own expense (subject to Section 6.5 and Exhibit A regarding TolerRx's US Profit/Loss Sharing Option), to be represented in any such action by counsel of its own choice.

Neither Party shall settle a dispute regarding the TolerRx Patent Rights without the consent of the other Party, which consent shall not be unreasonably withheld. Execution Copy - 31 - <Page> GENENTECH CONFIDENTIAL (3) Any damages or other monetary awards recovered pursuant to any suit, proceeding or other legal action taken under this Section 7.7(b) shall be allocated first to the costs and expenses of the Party bringing suit, and second to the costs and expenses (if any) of the other Party. The balance of any recovery shall be allocated between the Parties as follows: (i) to Genentech in an amount equal to its lost profits or a reasonable royalty on the sales of the infringer (whichever measure of damages shall have been applied), and (ii) to TolerRx in an amount equal to the royalties due TolerRx based on such sales (if sales of the infringer or a reasonable royalty measure of damages is applied) or a reasonable approximation of the royalties that Genentech would have owed to TolerRx on sales of Licensed Products that Genentech lost to the infringer (if a lost profits measure of damages is applied). With respect to royalties due to TolerRx, the previous sentence shall not apply to royalties related to the United States if TolerRx is participating in the US Profit/Loss Sharing Option in accordance with Section 6.5 and Exhibit A. Instead, in such circumstance, such balance related to damages for lost profits or reasonable royalty in the United States shall be added to the calculation of Other Operating Income/Expense (as defined in Exhibit A). The balance, if any, remaining after Genentech and TolerRx have been compensated as provided herein shall be allocated to the Party bringing suit. 7.8. THIRD PARTY PATENTS.

(a) In the event that a party materially breaches this Agreement (the "Defaulting Party"), the other party (the "Non-Defaulting Party") may provide written notice to Execution Copy - 34 - <Page> GENENTECH CONFIDENTIAL the Defaulting Party describing the breach. If the Defaulting Party in good faith disputes such breach and provides the Non-Defaulting Party in writing the grounds for disputing the breach within thirty (30) days after receipt of the notice of material breach from the Non-Defaulting Party, then the Non-Defaulting may not terminate this Agreement under this Section 9.3 and the Parties shall submit the dispute to arbitration in accordance with Section 12.13(b), and as provided in Section 9.3(b), hereinafter such dispute is a "Dispute" as defined in Section 12.13. In the event that the Defaulting Party does not provide a written notice of Dispute, and fails to cure such breach within ninety (90) days (thirty (30) days for a payment breach) of the written notice describing the breach, then the Non Defaulting Party shall have the right to terminate this Agreement by written notice to the Defaulting Party unless such breach is not capable of being cured within such ninety (90) day period. If the Defaulting Party does not provide a written notice of Dispute and if such breach is not capable of being cured within such ninety (90) day period (thirty (30) day period for a payment breach where no Dispute exists), then so long as the Defaulting Party is making diligent efforts to cure such breach within such amount of time as may be reasonably necessary to cure such breach, the Non-Defaulting Party may not terminate this Agreement under this Section 9.3(a) unless such breach is not cured within one-hundred and twenty (120) days of such notice.

If the Defaulting Party fails to cure such breach within such thirty (30) day period or as otherwise agreed, only then shall the Non-Defaulting Party have the right to terminate this Agreement under this Section 9.3. The time table for such arbitration proceeding for such Dispute shall be no more than one hundred twenty (120) days from its filing date to the award. The Parties shall submit to the Arbitration Panel at the initiation of the arbitration whether the disputed amount shall be placed in escrow and the decision of the Arbitration Panel in this respect shall be binding on the Parties.

In the event that there is an Adverse Judgment against the Defaulting Party, then prejudgment interest shall be awarded to the Non-Defaulting Party. The Party against which an Adverse Judgment is entered shall pay all costs of the arbitration including the attorneys fees of the other Party. 9.4. INSOLVENCY OR BANKRUPTCY.

EFFECT OF EXPIRATION OR TERMINATION (a) ACCRUED RIGHTS; SURVIVING OBLIGATIONS. Termination or expiration of this Agreement for any reason shall be without prejudice to any rights which shall have accrued to the benefit of either Party prior to such termination or expiration, and shall not relieve either Party from its obligations which are expressly indicated to survive expiration or termination of this Agreement, including, without limitation, those under Sections 3.4(b)(ii), 3.4(c)(i) (last three sentences only), 3.5(a), 7.1, 7.2, 8, 9.5(a), 9.5(b), 10, 11, and 12. Termination is not the sole remedy under this Agreement and, whether or not termination is effected, all other remedies at law and in equity will remain. (b) SUBLICENSES. No expiration or termination of this Agreement (except termination by Genentech without cause under Section 9.2 above) shall be construed as a termination of any sublicenses granted by Genentech under Section 5, and such sublicenses will remain in effect in accordance with their terms. (c) OTHER SURVIVING OBLIGATIONS. (i) Upon any termination of this Agreement by Genentech under Section 9.3 or 9.4, Genentech shall thereafter automatically have in perpetuity an irrevocable, exclusive (even as to TolerRx) sublicensable, fully transferable license within the Field in the Territory under TolerRx Patent Rights, TolerRx Know-how and TolerRx's joint ownership rights in Joint Patents (as defined in Section 7 herein), to make (and have made), use, sell, offer for sale and import, Licensed Products, subject to payment to TolerRx of only the applicable royalties under Sections 6.3 and 6.4 and applicable milestones under Section 6.2. For clarity, if Genentech terminates this Agreement under Section 9.3 or 9.4, Genentech shall not owe any other payments to TolerRx, including but not limited to Operating Profits or Losses, and shall only owe the applicable royalties under Sections 6.3 and 6.4 and applicable milestones under Section 6.2. Upon termination by Genentech under Section 9.3 or 9.4, (A) all obligations Execution Copy - 36 - <Page> GENENTECH CONFIDENTIAL and restrictions on Genentech shall terminate, except as expressly set forth in Sections 6.6, and 9.5(c)(i), and except for TolerRx's right as set forth in Section 6.8, but such right shall be limited only to verifying royalties under Sections 6.3 and 6.4 herein and (B) the following sections survive: Sections 7.5(d), 7.6(b), 7.7(b)(2), 5.3 (to the extent applicable), 9.5(a), 9.5(b), and other sections which are expressly indicated to survive termination. (ii) Upon any termination of this Agreement by TolerRx under Section 9.3 or 9.4 or by Genentech without cause under Section 9.2, (A) all rights granted to Genentech by TolerRx shall terminate and revert to TolerRx, and (B) all obligations and restrictions on Genentech and TolerRx shall terminate, including but not limited to Section 6, except those rights, obligations and restrictions that survive under Section 9.5(a) Section 9.5(b), and other sections which are expressly indicated to survive termination and (C) thereafter except as provided in Section 9.5 (c) (iii), Genentech shall cease and continue to cease to research, develop, manufacture, market and sell Licensed Product. Upon any termination by either Party under Section 9.3 or 9.4 or by Genentech without cause under Section 9.2, or upon expiration of the Agreement, all rights granted to TolerRx by Genentech (if any) shall terminate, except that in the case of termination by TolerRx under Section 9.3 or 9.4 or by Genentech without cause under Section 9.2, the rights (and only such rights) expressly set forth in Section 9.5(c)(iii) below shall continue (and only to the extent expressly set forth therein). (iii) This Section 9.5(c)(iii) shall only apply in the case of termination without cause by Genentech under Section 9.2 or termination by TolerRx under Section 9.3 or 9.4. For the purposes of this Section 9.5(c)(iii), except as expressly set forth in Section 9.5(c)(iii)(1) below, Licensed Product(s) shall only refer to existing Licensed Product(s) which Genentech was manufacturing in clinical or commercial quantities (if any) prior to such termination. (1) Only upon termination without cause by Genentech under Section 9.2 or termination by TolerRx under Section 9.3 or 9.4, subject to compliance with the terms and conditions of the Separate License Agreement for Genentech Patents (as defined below), TolerRx shall have a non-exclusive royalty-bearing, nontransferable, revocable (as provided below in Section 9.5(c)(iii)(6)), sublicensable, limited license under Genentech Patents solely to make, use, import, offer to sell and sell the Licensed Products that Genentech was manufacturing or developing prior to such termination. The Parties agree to negotiate in good faith the terms of a separate written agreement that will grant TolerRx such license rights (with royalty rates not to exceed [***] of net sales) ("Separate License Agreement for Genentech Patents"). With respect other patent rights owned by Genentech necessary for commercializing Licensed Products that Genentech was manufacturing in clinical or commercial quantities (if any) or developing prior to termination, if any, the Parties agree to negotiate in good faith regarding such rights. (2) TolerRx shall use best efforts to find a third party source of supply of Licensed Products. To the extent (A) Genentech has already been * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 37 - <Page> GENENTECH CONFIDENTIAL manufacturing clinical or commercial quantities of Licensed Product prior to such termination, and (B) to the extent that Genentech determines that doing the following would not adversely affect its manufacturing of its or its sublicensees' products, Genentech agrees to supply TolerRx (at Genentech's Fully Burdened Manufacturing Costs, plus a mark-up of twenty-five percent (25%)) at Genentech's election, with (A) a quantity of Licensed Products that is equivalent to a reasonable twelve-months' supply of Licensed Product or (B) such lesser amount of Licensed Products as is necessary for TolerRx to achieve the current milestone (and only that milestone) on which the Parties were working as of the effective date of termination. (3) At TolerRx's written request, if and only if Genentech has already been manufacturing clinical or commercial quantities of Licensed Product prior to such termination, then subject to compliance with the terms and conditions of this Agreement, Genentech agrees to provide either to TolerRx or to a designated Third Party contract manufacturer (and only to TolerRx or such manufacturer, but not both), who does not sell its own products and has expertise in recombinant protein manufacture and cell culture biology (including but not limited to having experience and know-how necessary to manufacture proteins at commercial scales), and who is reasonably acceptable to Genentech, Genentech's know-how, if any, specifically related to the manufacturing process of such existing Licensed Product and that is necessary for TolerRx or such Third Party to assume manufacture of such existing Licensed Product ("Licensed Product Manufacturing Know-how"). Licensed Product Manufacturing Know-how shall only consist of such know-how owned by Genentech (if any) that is necessary for TolerRx or such designated contract manufacturer to achieve the current milestone (and only that milestone) on which the Parties were working as of the effective date of termination. For example, if the Agreement is terminated during the Phase I Clinical Trial, then such Licensed Product Manufacturing Know-how to be transferred shall only consist of such know-how (if any) necessary to complete such Phase I Clinical Trial. Notwithstanding anything else, Licensed Product Manufacturing Know-how shall be limited to such know-how for manufacturing the agent targeting, binding to, or recognizing CD4 and shall exclude know-how related to any Genentech proprietary product or manufacture thereof. Such Licensed Product Manufacturing Know-how is deemed to be Confidential Information of Genentech regardless of whether such information is marked "Confidential." Without limiting TolerRx's obligations, TolerRx shall (and shall cause its contract manufacturer to) hold all such Licensed Product Manufacturing Know-how in confidence, not disclose such information to any person or entity (other than employees of TolerRx and such designated contract manufacturer bound to similar confidentiality obligations who have a legitimate "need to know") and to use such information solely for manufacturing the existing Licensed Product that Genentech was manufacturing in clinical or commercial quantities (if any) prior to such termination. For clarity, TolerRx shall (and shall cause such contract manufacturer to) not use such Licensed Product Manufacturing Know-how for any other purpose, including but not limited to any other product or process. TolerRx shall not allow any person or entity, other than itself or such designated contract manufacturer described above, to manufacture Licensed Product using Licensed Product Manufacturing Know-how. TolerRx's confidentiality obligations and indemnification under this Section 9.5(c)(iii)(3) and Section 9.5(c)(iii)(4) below shall survive in perpetuity, notwithstanding Execution Copy - 38 - <Page> GENENTECH CONFIDENTIAL Section 8.1 above or anything else. Any action or inaction by such contract manufacturer shall be deemed an action or inaction of TolerRx and TolerRx shall be responsible for any breach of any obligations hereunder by such contract manufacturer. Such contract manufacturer shall be bound by an enforceable writing for Genentech's benefit to at least the same limitations and restrictions as the limitations and restrictions on TolerRx. TolerRx indemnifies Genentech and its Affiliates and sublicensees from any and all claims, damages, liability, settlement, attorneys' fees and expenses, as incurred, on account of any breach of this Section 9.5 or any action or inaction of TolerRx or its contract manufacturer. For clarity, Licensed Product Manufacturing Know-how, if any, is provided nonexclusively, and remains Genentech's property and intellectual property at all times. (4) Genentech shall transfer to TolerRx, at TolerRx's cost, all Regulatory Approvals and applications for Regulatory Approvals for the Licensed Product(s) that Genentech holds at the time of termination. Genentech shall also provide to TolerRx all pre-clinical and clinical data produced by Genentech in developing the Licensed Products hereunder (if any) that Genentech holds at the time of termination. All of the foregoing Regulatory Approvals, applications therefor, and pre-clinical and clinical data shall be deemed Confidential Information of Genentech, notwithstanding Section 8.1 above or anything else, regardless of whether such information is marked "Confidential" or not, and shall be used only for the sale of such Licensed Product manufactured by TolerRx or by such contract manufacturer. TolerRx shall pay all costs associated with the transfers (including but not limited to out-of-pocket costs and fully-burdened personnel costs) in this Section 9.5(c)(iii). (5) The Parties agree that if Genentech provides such Licensed Product Manufacturing Know-how in accordance with this Section 9.5(c)(iii), then TolerRx has access to, is privy to, and may use such Licensed Product Manufacturing Know-how as set forth in this Section 9.5(c)(iii), and that it is impossible to determine the extent to which TolerRx has used such information. Accordingly, TolerRx agrees to pay the royalty set forth below on Net Sales of all Licensed Products. If Genentech has transferred Licensed Product Manufacturing Know-how to TolerRx or such Third Party contract manufacturer, TolerRx shall pay to Genentech a royalty to be negotiated in good faith between the Parties and not to exceed [***]. If the Parties agree on a lower royalty rate or if the foregoing royalty rate to be paid by TolerRx is [***], then Genentech shall be obligated to provide Licensed Product Manufacturing Know-how to the extent expressly set forth in this Section 9.5(c)(iii), otherwise Genentech shall not be obligated to provide Licensed Product Manufacturing Know-how. The terms applicable to Genentech (and payments by Genentech) under Sections 6.6 and 6.8 (including but not limited to the right for Genentech to audit TolerRx to verify the appropriate royalties owed to Genentech herein) shall apply to TolerRx and such royalty payments by TolerRx. TolerRx shall comply with the last sentence of Section 6.7, to the extent applicable. All payments hereunder due to Genentech shall be made in U.S. Dollars by bank wire transfer to the: [***]. The Parties shall agree to a process transfer plan for such Licensed Product Manufacturing Know-how and all of Genentech's obligations under this Agreement shall be deemed fulfilled when the tasks set forth in such plan are complete. * Confidential treatment requested: material has been omitted and filed separately with the Commission. Execution Copy - 39 - <Page> GENENTECH CONFIDENTIAL (6) Upon any breach of Section 9.5(c)(iii) herein by TolerRx, all rights and licenses granted to TolerRx and all obligations of Genentech under this Section 9.5(c)(iii) shall terminate immediately upon notice, and TolerRx shall immediately cease (and shall cause its contract manufacturer to cease) any and all use of Licensed Product Manufacturing Know-how, Genentech Patents and any other Confidential Information of Genentech, and shall return all copies, extracts, and derivatives of the foregoing to Genentech. This Section 9.5(c)(iii)(6) shall survive any termination of this Agreement. (7) Genentech agrees to negotiate in good faith with TolerRx regarding a royalty-bearing license to TolerRx for TolerRx's use of trademarks owned by Genentech with respect to Licensed Product. ARTICLE 10 INDEMNIFICATION 10.1. INDEMNIFICATION BY GENENTECH. Genentech hereby agrees to indemnify, defend and hold harmless TolerRx and its subsidiaries, parent corporations, Affiliates, officers, directors, agents, and employees, from and against any and all third party suits, claims, actions, demands, liabilities, settlements, expenses and/or loss (including reasonable legal expense and attorneys' fees) to the extent payable to such third party (collectively, "LOSSES") and arising out of or resulting from Genentech's or its third party sublicensee's performance of work under this Agreement, or the manufacturing, developing, distribution, testing, labeling, marketing, use or sale of Licensed Products by Genentech or its third party sublicensees in the Territory, except to the extent such Losses arise out of or result from the negligence or willful misconduct of TolerRx, TolerRx's breach of any terms of this Agreement or violation of any applicable law or regulation. For clarity, the foregoing does not include an indemnity regarding infringement of third party patent or trademark rights. In addition, Genentech hereby agrees to indemnify, defend and hold harmless TolerRx and its subsidiaries, parent corporations, Affiliates, officers, directors, and employees harmless from and against any and all Losses resulting from a breach by Genentech of any of its representations or warranties under Section 11.2 of this Agreement. 10.2. INDEMNIFICATION BY TOLERRX. TolerRx hereby agrees to indemnify, defend and hold harmless Genentech and its subsidiaries, parent corporations, Affiliates, officers, directors, agents, and employees from and against any and all Losses arising out of or resulting from TolerRx's performance of work (if any) or clinical trials under this Agreement or the testing, development or use of the Licensed Products or any actions of any TolerRx MSLs except to the extent such Losses arise out of or result from the negligence or willful misconduct of Genentech, Genentech's breach of any terms of this Agreement or violation of any applicable law or regulation. For clarity, the foregoing does not include an indemnity regarding infringement of third party patent or trademark rights. In addition, TolerRx hereby agrees to indemnify, defend and hold harmless Genentech and its subsidiaries, parent corporations, Affiliates, officers, directors, sublicensees and employees from and against any and Execution Copy - 40 - <Page> GENENTECH CONFIDENTIAL all Losses resulting from a breach by TolerRx of any of its representations or warranties under Section 11.1 of this Agreement. 10.3. NOTICE. A Party's compliance with this Section 10.3 is a condition of indemnification under this Section 10 by the other Party. A person or entity that intends to claim indemnification under this Section (the "Indemnitee") shall promptly notify the other Party (the "Indemnitor") of any loss, claim, damage, liability or action in respect of which the Indemnitee intends to claim such indemnification, and the Indemnitor shall assume sole control of the defense and settlement thereof with counsel selected by Indemnitor and reasonably satisfactory to the Indemnitee whether or not such third party claim is rightfully brought; provided, however, that an Indemnitee shall have the right to retain its own counsel to participate in such defense, with the fees and expenses to be paid by the Indemnitee. The indemnity agreement in this Section shall not apply to amounts paid in settlement of any loss, claim, damage, liability or action if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld or delayed unreasonably. The failure to deliver notice to the Indemnitor within a reasonable time after the commencement of any such action, only if prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Section. All delays of sixty (60) days or more shall be deemed prejudicial. Except as provided in the Agreement, the omission to so deliver notice to the Indemnitor will not relieve it of any liability that it may have to any Indemnitee otherwise than under this Section. The Indemnitee under this Section, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigations of any action, claim or liability covered by this indemnification and the defense thereof. The Indemnitor shall have the right to settle any loss, claim, damage, liability or action only if the Indemnitee is fully indemnified with respect thereto by the Indemnitor. A settlement requires the consent of the Indemnitee, which consent shall not be withheld unreasonably, only if the settlement requires Indemnitee to bear other affirmative obligations (beyond the payment of money damages and beyond obligations required by this Agreement). 10.4. INSURANCE. (a) During the Term, and thereafter for the period of time required below, each Party shall maintain an ongoing basis, COMMERCIAL GENERAL LIABILITY ("CGL") insurance, including contractual liability, in the minimum amount of $5,000,000 per occurrence and $10,000,000 annual aggregate combined single limit for bodily injury and property damage liability.

Thereafter Genentech shall maintain such insurance coverage without interruption during the Term and for 10 years after the expiration or termination of the Term. TolerRx shall maintain such insurance coverage without interruption during and after the Term until the later of: (A) 10 years after the expiration or termination of the Term or (B) ten (10) years after the last sale of the last Licensed Product in the Territory by TolerRx as permitted under Section 9.5(c)(iii), if applicable. Each Party shall provide certificates evidencing such insurance coverage without interruption on an annual basis (by no later than the annual renewal date for such coverage) during the period of time for which such coverage must be maintained. Each Party shall name the other Party as additional insureds under their respective CGL insurance and PL insurance policies. The CGL and PL insurance policies shall be an occurrence form, but if only a claims-made form is available, then it may be in a claims-made form, subject to compliance with all of the terms of this Section 10.4. Each of the above insurance policies shall be primary insurance with respect to each Party's own participation under this Agreement. The aggregate deductibles under such CGL and PL insurance policies shall be satisfactory to the other Party. At the request of either Party, the Parties agree to review and discuss the requirements under this Section 10.4. Such insurance coverage shall be subject to periodic review by the JSC and may be modified by the JSC. 10.5. SURVIVAL. This Section 10 shall survive termination or expiration of this Agreement. 10.6. LIMITATION OF LIABILITY. EXCEPT FOR NONPAYMENT BY EITHER PARTY, BREACH OF CONFIDENTIALITY OBLIGATIONS UNDER THIS AGREEMENT, SECTIONS 8, 9.5(c)(iii), 10 AND/OR 12.3 (AND/OR BREACH OF SUCH SECTIONS), IN NO EVENT SHALL EITHER PARTY BE LIABLE WITH RESPECT TO ANY SUBJECT MATTER OF THIS AGREEMENT UNDER ANY CONTRACT, NEGLIGENCE, STRICT LIABILITY OR OTHER LEGAL OR EQUITABLE THEORY (I) FOR ANY AMOUNTS IN EXCESS, IN THE AGGREGATE, OF THE FEES PAID TO TOLERRX HEREUNDER DURING THE TWELVE-MONTH PERIOD PRIOR TO THE DATE THE CAUSE OF ACTION AROSE OR (II) FOR ANY INDIRECT, EXEMPLARY, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES OR LOST DATA OR LOSS PROFITS OR (III) FOR ANY MATTER BEYOND SUCH PARTY'S REASONABLE CONTROL, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSS OR DAMAGE.

Each party shall nominate in the request for arbitration and the answer thereto one arbitrator and the two arbitrators so named will then jointly appoint the third arbitrator as chairman of the Panel. If one Party fails to nominate its arbitrator or, if the Parties' arbitrators cannot agree on the person to be named as chairman within thirty (30) days, the President of the American Arbitration Association shall make the necessary appointments for arbitrator or chairman. Execution Copy - 48 - <Page> GENENTECH CONFIDENTIAL (ii) The place of arbitration shall be in San Francisco, California and the arbitration proceedings shall be held in English.
