If Genentech decides not to proceed with the Development Program and Clinical Development Program, as the case may be, the Parties shall in good faith consider alternatives, including without limitation, modifying the Development Program and Clinical Development Program and/or licensing CTI to make, use and sell Licensed Product, or terminating this Agreement under Section 10.06(a). Notwithstanding the foregoing, Genentech shall not be obligated to grant CTI a license. If the Parties do not agree to work together further as provided in Section 10.06(a), either Party shall have the right to terminate this Agreement pursuant to Section 10.06(a). 4.06 SUPPLY AGREEMENT. Genentech and CTI shall negotiate in good faith a supply agreement for Clinical Product for Genentech and its permitted sublicensees for clinical trials outside the United States at such time as Genentech believes it is appropriate but no later than [ * ] after a decision by Genentech, if any, under Section 4.05(b) to proceed with the Clinical Development Program (the "Clinical Supply Agreement") and a supply agreement for Commercial Product for Genentech and its permitted sublicensees (the "Commercial Supply Agreement") at such time as the Development Committee believes it is appropriate, provided that negotiations for the Commercial Supply Agreement shall begin no later than the commencement of the first Phase II Clinical Trial and conclude no later than [ * ] prior to the expected commencement of the first Phase III Clinical Trial. The Parties shall use their best efforts to conclude the Clinical Supply Agreement within 90 days after Genentech's decision, if any, under Section 4.05(b) to proceed forward with the Clinical Development Program. CTI shall have the obligation to supply Genentech and its permitted sublicensees as provided herein and in such supply agreements. For purposes of this Agreement and each Supply Agreement, for supply of Clinical Product and Commercial Product by CTI to Genentech and its permitted sublicensees, CTI shall be entitled to CTI's Fully Burdened Manufacturing Cost for such Clinical Product, and, commencing with the First Commercial Introduction of the Licensed Product that is such Commercial Product, CTI's Fully Burdened Manufacturing Cost for such Commercial Product. The parties recognize that as part of such supply, there will be risks due to carrying inventory. Inside the United States, the Parties will apportion that inventory risk in proportion to the relevant profit participation of each Party pursuant to Sections 8.02 and 8.04. Outside the United States, such inventory risk * Confidential Treatment Requested 20 <PAGE> 21 shall be borne by Genentech pursuant to Sections 8.03 and 8.04. For these purposes, "inventory risk" shall be the risk of loss for Licensed Product subsequent to delivery of such Licensed Product to Genentech pursuant to a binding purchase order from Genentech. At the time the Parties begin to negotiate the Commercial Supply Agreement, they shall negotiate and agree in good faith a cap on both CTI's Fully Burdened Manufacturing Costs and Genentech's Sales, General and Administrative Expense. If either Party subsequently determines in good faith that its costs for these items will exceed the agreed upon cap, subject to review and approval by the Finance Committee, the Parties shall agree in writing to adjust the cap upward to equal the actual costs, for the period of time in which they exceed that cap. At the time the Parties enter into either Supply Agreement, they shall discuss whether and under what terms Genentech may purchase a joint ownership interest in the facilities producing Licensed Product. In addition to the above terms, the Commercial Supply Agreement shall contain a provision setting forth the minimum purchases that Genentech and its permitted sublicensees (in the aggregate) shall be required to make thereunder and the minimum supply capacity CTI must maintain to supply Licensed Product hereunder. Genentech, on behalf of itself and its permitted sublicensees, shall make first estimates (based on market projections) for purposes of required minimum purchases at the time of Genentech's entering into the Supply Agreement, and annually thereafter. CTI intends to use such estimates to determine the capacity of the plant it must build. Accordingly, CTI will not be required to produce more than [ * ] but shall be required to produce at least [ * ], of Genentech's purchase estimate, on behalf of itself and its permitted sublicensees, made closest to, but not less than, 18 months prior to First Commercial Introduction for each of the first three years that it supplies Commercial Product to Genentech and its permitted sublicensees. Actual purchases of Licensed Product supplied by CTI shall be pursuant to firm purchase orders from Genentech, but for purposes of maintaining the foregoing capacity protections for each Party in the Commercial Supply Agreement the Parties shall agree upon appropriate percentages beyond which such firm orders for supply of Licensed Product may not vary (above or below) the [ * ] range of the previously provided estimates, and CTI shall be obligated to supply, and Genentech (on behalf of itself and its permitted sublicensees) * Confidential Treatment Requested 21 <PAGE> 22 shall be obligated to purchase at least [ * ] of amounts of Licensed Product under such firm purchase orders in accordance with the foregoing and the "inventory risk" provisions set forth above in this Section 4.06. Genentech shall be permitted to revise its minimum purchase projections yearly, but such revision shall not affect the maximum amount of Commercial Product CTI must supply for the first three years. The Supply Agreement shall also provide for good faith, rolling forecasts covering a time period of at least 24 months with maximum supply obligations determined so as to allow Genentech and its permitted sublicensees to meet market needs and allow CTI reasonable time to build, validate and obtain approval of necessary facilities to supply Licensed Products in the Territory. The Supply Agreement shall contain a provision to protect CTI against idle plant capacity after expansion of such facilities, to the extent such facilities were built to supply such Licensed Product (with reasonable apportionment where other parties, including CTI, are also supplied by such plant capacity). The Supply Agreement shall provide that CTI shall treat Genentech and its permitted sublicensees as CTI's highest priority customer for supply of Licensed Product, and shall provide for flexibility for Genentech and its permitted sublicensees to change purchase orders and require CTI to promptly replace non-conforming or otherwise defective product supplied thereunder. In addition, each Supply Agreement shall contain provisions regarding breach similar to those set forth in this Agreement, including those governing the transfer of manufacturing technology from CTI to Genentech for manufacture of Licensed Product in the Territory and shall provide that a breach under such Supply Agreement shall be a breach hereunder. During the period of such a transfer, CTI shall continue to treat Genentech on behalf of it and its permitted sublicensees as its highest priority customer for supply of Licensed Product. The Parties agree that the technology transfer will involve the need for CTI employees to train Genentech employees. CTI will pay the salaries of its employees doing such training, and Genentech will pay the salaries of its employees receiving such training as well as all expenses incurred in constructing a Genentech facility for producing Licensed Product. 4.07 (a) FUNDING OF DEVELOPMENT THROUGH THE INITIAL CLINICAL TRIAL. Pursuant to Section 8.01(a), Genentech has agreed to purchase the agreed-upon amount of Common Stock to provide funding for Development Expenses. If CTI reasonably determines that Development Expenses will exceed those previously agreed-upon, it shall notify Genentech. The Parties shall meet and agree if additional * Confidential Treatment Requested 22 <PAGE> 23 Development Expenses beyond those agreed-upon will be required. If the Parties agree additional Development Expenses will be incurred and on the amount of such additional Development Expenses, to the extent that such agreed-upon CTI Development Expenses will exceed the funding provided by Genentech's equity purchase pursuant to Section 8.01(a), Genentech shall purchase sufficient additional equity, pursuant to an agreement in the form of the Stock Purchase Agreement and at a price equal to one hundred percent (100%) of the 20 Day Average of CTI's Common Stock, to fund in advance, the remainder of such agreed-upon CTI Development Expenses. In no case shall CTI be required to fund such additional expenses unless Genentech, in fact, makes the additional equity purchase contemplated hereunder to cover such Development Expenses. If the amount of funding received by CTI pursuant to Sections 4.07(a) and 8.01(a) exceeds the Development Expenses incurred by CTI through the completion of analysis of the results of the Initial Clinical Trial or as of any earlier termination of the Development Program or this Agreement, CTI shall provide written notice to Genentech of the amount of such "overfunding". CTI shall apply such "overfunding" to the Clinical Development Expenses to be incurred by CTI under Section 4.07(b), except as otherwise provided hereinbelow, and except that if such "overfunding" totals [ * ] or less, CTI shall be entitled to retain such excess and shall not be required to apply it against any future work under this Agreement or against redemption of CTI's Common Stock as otherwise provided hereinbelow. Subject to the foregoing, if the amount of such funding under Sections 4.07(a) and 8.01(a) exceeds the Development Expenses incurred by CTI and CTI cannot apply such "overfunding" to the Clinical Development Expenses to be incurred because (i) Genentech has determined pursuant to Section 4.05 not to proceed forward with the Clinical Development Program or (ii) this Agreement has been terminated at any time for any other reason (except termination by CTI in accordance with this Agreement due to Genentech's uncured default, in which case the provisions of this paragraph shall apply except that CTI shall be entitled to retain "overfunding" in an amount equal to CTI's already incurred costs for its work under this Agreement), then Genentech shall have the rights and CTI the obligations set forth hereinbelow. If Genentech so requests in writing within sixty (60) days after, as applicable, Genentech's decision under Section 4.05 not to proceed forward or the effective date of termination of this Agreement (except as otherwise provided above with respect to Genentech's uncured default), within thirty (30) days after such request CTI shall pay such overfunding * Confidential Treatment Requested 23 <PAGE> 24 amount to Genentech against Genentech's delivery to CTI of that number of shares of CTI's Common Stock equal to such overfunding amount divided by the price for such Common Stock paid by Genentech under Section 8.01(a) (or, if such overfunding is attributable only to CTI's receipt of additional funding from Genentech under 4.07(a), the price paid for such Common Stock under Section 4.07(a)). In calculating the overfunding amount, CTI shall calculate the total amount of expenses incurred by CTI hereunder based on the total expenses incurred for performance of the tasks approved by the Development Committee (without regard to categories of budgeted amounts). (b) FUNDING OF DEVELOPMENT THROUGH PHASE II CLINICAL TRIAL ANALYSIS. Upon Genentech's decision pursuant to Section 4.05(b) to commence the Clinical Development Program, pursuant to Section 8.01(b) Genentech will purchase Common Stock pursuant to an agreement in the form of the Stock Purchase Agreement, in an amount equal to the agreed-upon Phase II Clinical Development Expenses. If CTI reasonably determines that its Phase II Clinical Development Expenses will exceed those previously agreed-upon (subject to the following paragraph), it shall notify Genentech. The Parties shall meet and agree if additional Phase II Clinical Development Expenses beyond those agreed-upon will be required. If the Parties agree additional Phase II Clinical Development Expenses will be incurred and on the amount of such additional expenses, to the extent that such agreed-upon CTI Phase II Clinical Development Expenses will exceed the funding provided by Genentech's equity purchase pursuant to Section 8.01(b), Genentech shall purchase sufficient additional equity, pursuant to an agreement in the form of the Stock Purchase Agreement and at a price equal to one hundred percent (100%) of the 20 Day Average of CTI's Common Stock, to fund, in advance, the remainder of such agreed-upon CTI Phase II Clinical Development Expenses. In no case shall CTI be required to fund such additional Phase II Clinical Development Expenses unless Genentech, in fact, makes the additional equity purchase contemplated hereunder to cover such Phase II Clinical Development Expenses. If the amount of funding received by CTI pursuant to Sections 4.07(a) and (b) and 8.01(b) exceeds the Development Expenses and Clinical Development Expenses incurred by CTI through the completion of analysis of the results of the last Phase II Clinical Trial of a Licensed Product prior to commencement of funding under Section 4.07(d), or as of any earlier termination of the Clinical Development Program or this 24 <PAGE> 25 Agreement, CTI shall provide written notice to Genentech of the amount of such "overfunding". CTI shall apply such "overfunding" to CTI's share of the U.S. Phase III Clinical Development Expenses to be borne by CTI pursuant to Section 4.07(d), except that if such "overfunding" totals [ * ] or less, CTI shall be entitled to retain such excess and shall not be required to apply it against any future work under this Agreement or redemption of CTI's Common Stock as otherwise provided hereinbelow. Subject to the foregoing, if the amount of funding under Sections 4.07(a) and (b) and 8.01(b) exceeds the Development Expenses and Clinical Development Expenses incurred by CTI and CTI cannot apply such "overfunding" to its share of the U.S. Phase III Clinical Development Expenses to be borne by CTI because (i) Genentech has determined pursuant to Section 4.05 not to proceed forward with the Clinical Development Program or (ii) this Agreement has been terminated at any time for any other reason (except termination by CTI in accordance with this Agreement due to Genentech's uncured default, in which case the provisions of this paragraph shall apply except that CTI shall be entitled to retain "overfunding" in an amount equal to CTI's already incurred costs for its work under this Agreement), then Genentech shall have the rights and CTI the obligations set forth hereinbelow. If Genentech so requests in writing within sixty (60) days after, as applicable, Genentech's decision under Section 4.05 not to proceed forward or the effective date of termination of this Agreement (except as otherwise provided above with respect to Genentech's uncured default), within thirty (30) days after such request CTI shall pay such overfunding amount to Genentech against Genentech's delivery to CTI of that number of shares of CTI's Common Stock equal to such overfunding amount divided by the price for such Common Stock paid by Genentech under Section 8.01(b) (or, if such overfunding is attributable only to CTI's receipt of additional funding from Genentech under 4.07(b), the price paid for such Common Stock under 4.07(b)). In calculating the overfunding amount, CTI shall calculate the total amount of expenses incurred by CTI hereunder based on the total expenses incurred for performance of the tasks approved by the Development Committee (without regard to categories of budgeted amounts). (c) RECORDS. In connection with any application of "overfunding" to future work or redemption of CTI Common Stock as provided in Sections 4.07(a) or (b), CTI shall keep complete and accurate records of its expenses hereunder, and Genentech shall have the right, upon written request after reasonable notice, to have an independent certified public accountant reasonably acceptable to CTI, review such records for the * Confidential Treatment Requested 25 <PAGE> 26 purposes of verifying such "overfunding", if any. This right may not be exercised more than once in any calendar year. Results of such review shall be made available to both Parties. The provisions of Sections 4.07(a), (b) and (c) regarding overfunding shall survive any termination of this Agreement. (d) FUNDING OF U.S. PHASE III CLINICAL DEVELOPMENT EXPENSES. If Genentech decides to continue the Clinical Development Program after the review under Section 4.05(c), the Parties shall agree on a budget for U.S. Phase III Clinical Development Expenses. As provided below in this Section 4.07(d), CTI shall pay [ * ] of the agreed-upon U.S. Phase III Clinical Development Expenses; such [ * ] shall be financed by Genentech providing CTI with a revolving line of credit in the principal amount of the to be agreed-upon [ * ] of U.S. Phase III Clinical Development Expenses (less the amount of any overfunding, if any, applied by CTI as provided in Section 4.07(b)), which line of credit shall bear interest on the outstanding principal amount at a rate equal to LIBOR (as quoted for one month in The Wall Street Journal) plus [ * ] compounded quarterly. Subject to Section 10.07(a), such revolving loan shall be repaid in full (and shall not be available for further borrowing by CTI) within [ * ] days after the earlier of (i) seven (7) years from the date funds are first drawn down under such line of credit or (ii) the earlier of (A) of the completion of the analysis of all U.S. Phase III Clinical Trial(s) directed by the Development Committee, (B) termination of the last U.S. Phase III Trial (if terminated prior to its term), or (C) termination of this Agreement (as provided in Section 10.07 (a)(ii)). Notwithstanding the foregoing, under the loan documentation to be entered into by the Parties, in the event of any event of default under such loan documentation, including any CTI failure to repay the total amount of the loan (principal plus interest) then outstanding, Genentech shall have the right to convert the total amount of the loan outstanding into registered shares of Common Stock of CTI. Such revolving loan may be prepaid by CTI at any time; CTI shall give Genentech at least [ * ] days notice of any such prepayment. CTI may make any payment under such loan in whole or in part by issuing to Genentech shares of CTI stock, which shall be valued at price per share equal to one hundred percent (100%) of the 20 Day Average of CTI's Common Stock. The loan under the revolving line of credit shall be unsecured and fully subordinated to all other CTI liabilities. * Confidential Treatment Requested 26 <PAGE> 27 At the time, if any, that Genentech elects to proceed under Section 4.05(c) to a U.S. Phase III Clinical Trial, the Parties shall agree on any additional necessary terms of the line of credit. The Parties expect to pay for U.S. Phase III Clinical Development Expenses equally. The Parties shall invoice each other for actual U.S. Phase III Clinical Development Expenses; [ * ] is payable by Genentech. Genentech shall pay the full amount it owes under such invoices and shall draw down from the line of credit the amount CTI owes under such invoices, as contemplated by this Section 4.07(d). If at any time either Party has paid more than its share of such expenses, as provided in this Agreement, the Parties shall fairly adjust the reimbursement of such expenses. Each Party shall keep complete and accurate records of the latest three (3) years of its U.S. Phase III Clinical Development Expenses. Each Party shall have the right at its own expense to have an independent certified public accountant, reasonably acceptable to the other Party, review such records upon reasonable notice and during reasonable business hours for the purposes of verifying reimbursement hereunder. This right may not be exercised more than once in any calendar year. Results of such review shall be made available to both Parties. If the review reflects an overpayment of U.S. Phase III Clinical Development Expenses by either Party, any such overpayment shall be promptly remitted to the other Party with interest as provided in Section 8.04. If the overpayment is equal to or greater than five percent (5%) of invoiced U.S. Phase III Clinical Development Expenses, the overpaying Party shall be entitled to have the other Party pay all of the costs of such review. The provisions of this Section 4.07(d) shall survive termination of this Agreement. ARTICLE V GRANT OF RIGHTS 5.01 GRANT BY CTI. CTI hereby grants to Genentech, under the CTI Patent Rights and CTI Knowhow, (i) a co-exclusive license (with CTI) to [ * ] such Patent Rights and Knowhow for [ * ] of Licensed Products in the United States in accordance with the Development Program agreed upon by the Parties, and (ii) an * Confidential Treatment Requested 27 <PAGE> 28 exclusive license (even as to CTI) to [ * ] Licensed Products in the Territory outside the United States, and to [ * ] Licensed Products throughout the Territory and (iii) in the event that manufacturing technology is transferred to Genentech pursuant to Section 10.04, an exclusive license to [ * ] Licensed Products in the Territory. 5.02 GRANT BY GENENTECH.

Commencing with the First Commercial Introduction of the Licensed Product outside the United States and subject to the other terms hereof (including, without limitation, Section 10.04), during the term of this Agreement, Genentech agrees to pay CTI, as consideration for the rights granted hereunder, [ * ] of Net Sales of Licensed Product by Genentech and its sublicensees in the Territory outside the United States and (ii) payment for such Licensed Product, if supplied by CTI hereunder, as provided in Section 4.06 and the Commercial Supply Agreement. 8.04 PAYMENT DATES AND STATEMENTS. Within sixty (60) days of the end of each Accounting Period in which Net Sales occurred for purposes of Section 8.02 and ninety (90) days of the end of each Accounting Period in which Net Sales occurred for purposes of Section 8.03, Genentech shall calculate all amounts owed by Genentech to CTI under Section 8.02 or 8.03 and shall send to CTI the net amount owed to CTI or, if appropriate, a statement of the loss carried forward by Genentech on behalf of CTI plus interest thereon as specified herein. Such payment shall be accompanied by a statement for the Accounting Period showing the calculation of the amount owed and for each country in the Territory, the total Net Sales of each Licensed Product by * Confidential Treatment Requested 34 <PAGE> 35 Genentech and its permitted sublicensees, the exchange rate used to directly convert any of the above amounts into U.S. Dollars, and, in the case of Net Sales inside the United States, the Cost of Sales for each Licensed Product during that Accounting Period, the Sales, General and Administrative Expense (and the calculation thereof), the Launch Expenses, the Phase IV Clinical Trial Expenses, the Net Profit, and the amount of any CTI loss carried forward. For purposes of determining when a sale of a Licensed Product occurs, the sale shall be deemed to occur on the date the Licensed Product is shipped to a third party. Any payment owed under Section 8.02 or 8.03 that is not paid on or before the date such payment is due under this Agreement shall bear interest, to the extent permitted by applicable law, at two percentage points (2%) over the prime rate of interest as reported by Bank of America NT&SA in San Francisco, California from time to time, calculated on the number of days such payment is delinquent. 8.05 RECORDS AND ACCOUNTING (a) Genentech and its permitted sublicensees shall keep complete and accurate records of the latest three (3) years of Net Sales and, for sales of Licensed Products in the United States, Cost of Sales, Sales, General and Administrative Expense, Launch Expenses and Phase IV Clinical Trial Expenses. CTI shall have the right at its own expense to have an independent, certified public accountant, reasonably acceptable to Genentech (or any relevant sublicensee), review such records upon reasonable notice and during reasonable business hours for the purposes of verifying royalties payable to CTI, Net Sales, and Net Profits. This right may not be exercised more than once in any calendar year. Results of such review shall be made available to both Parties. If the review reflects an underpayment of royalties or Net Profits to CTI, such underpayment shall be promptly remitted to CTI with interest as provided in Section 8.04. If the underpayment is equal to or greater than five percent (5%) of Net Profits that was otherwise due, CTI shall be entitled to have Genentech pay all of the costs of such review. If the review reflects an overpayment of royalties and Net Profits to CTI, royalties and Net Profits for the period of such overpayment shall be recalculated and any amount due to Genentech shall be promptly paid. (b) CTI and its permitted sublicensees shall keep complete and accurate records of the latest three (3) years of Fully Burdened Manufacturing Cost, and shall provide Genentech with a report setting forth all such items within forty-five (45) days of 35 <PAGE> 36 the end of each Accounting Period. Genentech shall have the right at its own expense to have an independent, certified public accountant, reasonably acceptable to CTI, review such records upon reasonable notice and during reasonable business hours for the purposes of verifying the Fully Burdened Manufacturing Cost. This right may not be exercised more than once in any calendar year. Results of such review shall be made available to both Parties. If the review reflects an overpayment of the Fully Burdened Manufacturing Cost to CTI, such overpayment shall be promptly refunded to Genentech with interest as provided in Section 8.04. If the overpayment is equal to or greater than five percent (5%) of the Fully Burdened Manufacturing Cost, Genentech shall be entitled to have CTI pay all of the costs of such review. If the review reflects underreporting of CTI's Fully Burdened Manufacturing Cost, Fully Burdened Manufacturing Cost for the period of such underreporting shall be re-calculated and any amounts due to CTI shall be promptly paid. 8.06 CURRENCY OF PAYMENTS. All payments under this Agreement shall be made in United States Dollars by check or wire transfer (or such other reasonable means as a receiving Party may direct) to such bank account as may be designated from time to time. Any payments due hereunder on Net Sales outside of the United States shall be payable in United States Dollars calculated pursuant to U.S. generally accepted accounting principles consistently applied at the rate of exchange of the currency of the country in which the Net Sales were made, with such rate as is equal to the average of the rates reported in The Wall Street Journal for the first and last business day of the Accounting Period for which the Net Profit Amount or royalties are payable. 8.07 TAX WITHHOLDING. If any withholding taxes are required under the applicable laws of any country or any applicable treaty on royalty payments made hereunder, the selling Party will pay such taxes to the proper taxing authority and such tax payment will be deducted by the selling Party from the royalty payable to the owed Party. Written documentation of any such payment sufficient to satisfy the reasonable requirements of an appropriate tax authority concerning an application by the owed Party for a foreign tax credit for such payment or for similar treatment shall be secured and sent to the owed Party. The selling Party agrees to take such reasonable and lawful steps as the owed Party may request to minimize the amount of withholding taxes that must be paid pursuant to any applicable treaty to the extent permitted by such treaty. If either Party to this Agreement, by reason of the assignment of its rights 36 <PAGE> 37 under this Agreement, as specified in Section 11.02, increases the withholding tax payable by the non-assigning Party in any taxing jurisdiction, then the assigning Party agrees to pay the non-assigning Party an amount which, net of any tax benefits which the non-assigning Party may use, would be the same as if the assignment had not occurred. 8.08 FINANCE COMMITTEE. In connection with the sharing of Net Profits contemplated under Section 8.02, within thirty (30) days after Genentech's notice of exercise of its right to continue the Clinical Development Program after the review under Section 4.05(c), the Parties will establish a joint finance committee (the "Finance Committee"), to be comprised of two (2) representatives appointed and replaced by each Party. Such representatives will include individuals with expertise and responsibilities in the areas of accounting, cost allocation, budgeting or financial reporting. The Finance Committee will meet as requested by either Party by notice to the other Party (but in any event not more frequently than quarterly), at such times and locations as are reasonably acceptable to the Parties. All decisions and recommendations of the Finance Committee shall require the agreement of a majority of the representatives of each Party to be effective. In the event the representatives of the two Parties cannot agree on a matter, a member of senior management of each party shall confer and resolve the dispute. For this purpose, a "member of senior management" shall be a management-level employee who has the authority to bind a Party. If the members of senior management do not resolve such dispute within 60 days of such objection, the Parties shall attempt to resolve such dispute in accordance with Sections 11.19 and 11.20. The Finance Committee shall address financial, budgeting and accounting issues which arise in connection with the sharing of Net Profits contemplated under Section 8.02 above (including, without limitation, review of the Parties' respective cost structures and generally accepted accounting principles and other practical aspects of implementation of the terms of this Agreement and the amount of Cost of Sales, Fully Burdened Manufacturing Cost, Sales, General and Administrative Expense, Launch Expenses and Phase IV Clinical Trial Expenses) and the proper allocation of such costs in determining Net Profits. The Finance Committee (if any) automatically will cease to operate upon the expiration of the term of this Agreement. 37 <PAGE> 38 ARTICLE IX CONFIDENTIALITY AND DISTRIBUTION OF KNOWHOW 9.01 NON-DISCLOSURE. Except to the extent expressly authorized by this Agreement, the Parties agree that, for the term of this Agreement and for seven years thereafter (15 years in the case of manufacturing technology), the receiving Party shall keep completely confidential and shall not publish or otherwise disclose and shall not use for any purpose other than as contemplated by this Agreement any information furnished to it by the other Party pursuant to this Agreement (other than to employees or consultants on a need-to-know and confidential basis), except to the extent that it can be established by the receiving Party by competent proof that such information: (a) was already known to the receiving Party, other than under an obligation of confidentiality, at the time of disclosure by the other Party; (b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party; (c) became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement; or (d) was subsequently lawfully disclosed to the receiving Party by a third party. Information that is disclosed other than in written form shall be subject to the terms of this Section 9.01 only if confirmed in writing within thirty (30) days of disclosure and specifying that such information is subject to this Agreement. Each Party may disclose the other's information to the extent such disclosure is reasonably necessary in filing or prosecuting patent applications, prosecuting or defending litigation, complying with applicable governmental regulations or conducting clinical trials, provided that, if a Party proposes to make any such disclosure of the other Party's secret or confidential information, it will give reasonable advance notice to the other Party of such disclosure and, save to the extent inappropriate in the case of patent applications, will use its best efforts to secure confidential treatment of such information required to be disclosed. A Party may disclose confidential information to 38 <PAGE> 39 a potential sublicensee or assignee to the extent reasonably required to negotiate a sublicense or assignment permitted hereunder; provided, however, that such potential sublicensee or assignee shall first execute a binding confidentiality agreement of term and scope at least as restrictive as the terms of this Article IX, and which confidentiality agreement shall expressly provide that the non-disclosing Party is intended to be a third-party beneficiary thereof. 9.02 PUBLICATION. Notwithstanding Section 9.01, each Party shall be free to publish the results of its activities conducted hereunder, to the extent that publication will not result in the disclosure of otherwise confidential data or Knowhow and will not conflict with the terms of the Neurturin MTA. Subject to the foregoing, at least 30 days prior to making any such publication (14 days in the case of an abstract), the publishing Party shall provide the other Party a draft of the proposed publication to afford an opportunity for comment and securing of intellectual property rights. Publication shall be delayed an additional 30 days to permit filing of patent applications upon request. Neither Party may publish the other's Knowhow without the prior written consent of the other Party. 9.03 DISTRIBUTION OF KNOWHOW. Neither Party shall transfer any of the other Party's Knowhow (including without limitation, any Factors or genetic materials encoding therefor provided by such other Party or any proprietary information of such other Party under Section 9.01) to any third party without the express prior consent of the Party which provided such Knowhow, provided either Party may make such disclosures as are required by law or a court order (but before any such required disclosure it shall notify the other Party) or as are required as part of regulatory submissions or as required in sublicensing (provided that in cases of sublicensing, the entity receiving such Knowhow agrees to confidentiality and nonuse provisions at least as restrictive as those in this Article IX). ARTICLE X TERM AND TERMINATION 10.01 TERM. The term of this Agreement shall commence as of the Effective 39 <PAGE> 40 Date set forth above. Unless sooner terminated pursuant to Sections 10.02, 10.03, 10.05 or 10.06, the term of this Agreement, the licenses granted in Sections 5.01 and 5.02 and Genentech's obligations with respect to Net Profits and royalties under Sections 8.02 and 8.03 shall expire on a [ * ] years from the date of First Commercial Introduction in that country. Subject to the other terms of this Agreement (including this Section 10.01), upon expiration of this Agreement on such country-by-country and Licensed Product-by-Licensed Product basis, Genentech shall have a perpetual, fully paid up, non-exclusive right and license under the CTI Knowhow and CTI Patent Rights, and any improvements thereto solely or jointly owned by CTI under Section 7.01, to develop, make, have made, use and sell such Licensed Products in such country in the Territory, and a perpetual, fully paid up, exclusive right and license in such country in the Territory to improvements to the Genentech Knowhow or Genentech Patent Rights solely developed or invented and solely owned by CTI under Section 7.01. Subject to the other terms of this Agreement, upon expiration of this Agreement CTI shall have a perpetual, fully paid-up, exclusive right and license in such country in the Territory to improvements to the CTI Knowhow or CTI Patent Rights solely developed or invented and solely owned by Genentech under Section 7.01. No later than [ * ] prior to the expiration of the term of the licenses granted hereunder, the Parties shall discuss the status of their relationship and shall agree, if Licensed Product is still being marketed hereunder anywhere in the world solely by Genentech or its sublicensee(s), either to extend the Supply Agreements or to transfer manufacturing technology and all necessary licenses to Genentech. Any such extended Supply Agreement(s) shall provide for a supply price of [ * ] of (i) Fully Burdened Manufacturing Cost plus [ * ] or (ii) the cap on Fully Burdened Manufacturing Cost agreed upon pursuant to Section 4.06. If no agreement is reached on supply prior to two years before such expiration, CTI shall transfer all necessary manufacturing technology in CTI's possession or control and grant all necessary licenses under the CTI Patents and CTI Knowhow (including any improvements hereunder) to Genentech (with right to sublicense) for the nonexclusive rights to make, have made, use and sell Licensed Product then under sale in the Field of Use in the Territory (but for no other purpose) and CTI shall permit Genentech and its sublicensees to reference or otherwise get the benefit of any necessary regulatory filings necessary to permit such manufacture and sale of Licensed Product. All such licenses shall be fully paid up (subject to the cost reimbursement provided below). In the event of a transfer of such technology and granting all necessary licenses to * Confidential Treatment Requested 40 <PAGE> 41 Genentech upon the expiration of this Agreement, Genentech shall reimburse CTI for all reasonable costs incurred by it as part of such transfer, and Genentech shall be responsible for the payment of all royalties and other amounts contractually required to be paid by CTI to third parties on account of such manufacture, use or sale by Genentech or its sublicensees. 10.02 BREACH. Failure by either Party to comply with any of its material obligations contained in this Agreement shall entitle the other Party to give to the Party in default notice specifying the nature of the default and requiring it to make good such default. If such default is not cured within 60 days after the receipt of such notice, the notifying Party shall be entitled, without prejudice to any of its other rights conferred on it by this Agreement, in addition to any other remedies available to it by law or in equity, to terminate this Agreement unless the defaulting Party shall cure such default within said 60 days. The right of either Party to terminate this Agreement, as hereinabove provided, shall not be affected in any way by its waiver of failure to take action with respect to any previous default. 10.03 INSOLVENCY OR BANKRUPTCY. Either Party may, in addition to any other remedies available to it by law or in equity, terminate this Agreement by written notice to the other Party in the event the other Party shall have become insolvent or bankrupt, or shall have made an assignment for the benefit of its creditors, or there shall have been appointed a trustee or receiver of the other Party or for all or a substantial part of its property, or any case or proceeding shall have been commenced or some other action taken by or against the other Party in bankruptcy or seeking reorganization, liquidation, dissolution, winding-up, arrangement, composition or readjustment of its debts or any other relief under any bankruptcy, insolvency, reorganization or other similar act or law of any jurisdiction now or hereafter in effect or there shall have been issued a warrant of attachment, execution, distraint or similar process against any substantial part of the property of the other Party, and any such event shall have continued for 60 days undismissed, unbounded and undischarged; provided, however, that no such right to terminate shall pertain solely by virtue of a voluntary reorganization for the purpose of solvent amalgamation or reconstruction. 10.04 TRANSFER OF TECHNOLOGY. (a) Upon termination of this Agreement due to Genentech's fundamental breach (including, without limitation, a failure to pay CTI Net Profits or royalties on Net Sales owed hereunder) or bankruptcy, the licenses 41 <PAGE> 42 granted in Article V to Genentech shall terminate, and, Genentech shall grant to CTI a Territory-wide, exclusive license to develop, make, have made, use and sell Licensed Product in the Field of Use in the Territory (but for no other purpose) under the Genentech Patents and Knowhow solely or jointly owned by Genentech with CTI hereunder (including any improvements hereunder) with the right to sublicense and the right to reference or otherwise get the benefit of any necessary regulatory filings of Genentech or its sublicensees, and, upon the request of CTI, Genentech shall transfer to CTI any technology in its possession or control under the scope of such license and necessary for CTI to develop, make, have made, use or sell Licensed Product in the Field of Use in the Territory (but for no other purpose). CTI shall pay Genentech royalties in the amount of [ * ] of Net Sales of Licensed Product by CTI and its sublicensees and shall be responsible for all of Genentech's obligations hereunder. In addition to the royalties to be paid to Genentech, CTI shall be responsible for reimbursing Genentech for the payment of all royalties and other amounts contractually required to be paid by Genentech to third parties on account of such manufacture, sale or use of Licensed Product by CTI or its sublicensees. (b) Upon termination of this Agreement due to CTI's fundamental breach (e.g., failure to supply Licensed Product as provided herein or in the Supply Agreement(s)) or bankruptcy, the licenses granted to CTI in Article V shall terminate, and, CTI shall grant to Genentech a Territory-wide, exclusive license to develop, make, have made, use and sell Licensed Product in the Field of Use in the Territory (but for no other purpose) under the CTI Patents and Knowhow, solely or jointly owned hereunder by CTI with Genentech (including any improvements hereunder) with the right to sublicense and the right to reference or otherwise get the benefit of any necessary regulatory filings of CTI or its sublicensees, and upon the request of Genentech, CTI shall transfer to Genentech any technology in its possession or control under the scope of such license and necessary for Genentech to develop, make, have made, use and sell Licensed Product in the Field of Use in the Territory (but for no other purpose). Genentech shall pay CTI royalties in the amount of [ * ] of Net Sales of Licensed Product in the Field of Use in the Territory by Genentech and its sublicensees and shall be responsible for all of CTI's obligations hereunder. In addition to the royalties to be paid to CTI, Genentech shall be responsible for reimbursing CTI for payment of all royalties and other amounts contractually required to be paid by CTI to third parties on account of such manufacture, sale or use of Licensed Product by Genentech or its sublicensees, but Genentech shall be entitled to * Confidential Treatment Requested 42 <PAGE> 43 offset against such royalty and other payments to CTI all of Genentech's out-of-pocket costs and expenses incurred in constructing facilities to manufacture Licensed Product in the Territory and obtaining approval of an establishment license application or equivalent regulatory approval of such manufacturing facilities. Genentech's right to offset its out-of-pocket costs of construction and approval shall be limited to those expenses reasonably incurred related to constructing a facility similar to the plant being used by CTI to produce Licensed Product hereunder. CTI shall have the option, in lieu of the foregoing offsets, of transferring to Genentech the ownership and/or control of the plant (with all liabilities incurred in connection with the construction, validation and approval of such plant) it is using at the time to supply Licensed Product hereunder. Genentech may reasonably refuse to accept such transfer, in which case Genentech's right to offset shall continue. Genentech may request that CTI transfer its technology to a third party solely for the manufacture of Licensed Product. CTI may reasonably withhold its consent to a transfer to a particular third party, but may not reject all possible reasonable third party candidates for such a transfer put forth by Genentech. During the period of such a transfer, CTI shall treat Genentech as its first priority customer for supply of Licensed Product. The Parties agree that the technology transfer will involve the need for CTI employees to train Genentech or its third party designee's employees. CTI will pay the salaries of its employees doing such training but will not be responsible for the payment of the salaries of Genentech or third party employees receiving training. Genentech will be responsible for all other obligations of CTI under this Agreement. 10.05 MUTUAL AGREEMENT. The Parties may terminate any development program or this Agreement by mutual agreement at any time. 10.06 SPECIAL TERMINATION RIGHTS. (a) If Genentech elects not to continue the Development Program or the Clinical Development Program pursuant to Section 4.05 and the Parties do not agree to a new program hereunder within ninety (90) days, either Party may terminate this Agreement on ninety (90) days written notice to the other Party.

Generally speaking, CTI creates encapsulated cells containing implants using a number of techniques and technologies, including the following; each kind of implant will use various of the following depending on the cell type, the implant location and the proteins to be released: - BIOMATERIALS - Creation, selection, characterization, purification, and validation of implant materials (including without limitation, PAN/PVC, PES, polyurethanes, and mesh materials (with and without hydrogels)) formulation and fabrication and, where necessary, surface modification of (E.G., with PEO, PVA, etc.), molecularly-separative membranes (E.G., with appropriate transport properties and sufficient biocompatibility for successful encapsulation); selection, treatment, and/or synthesis of an intracapsular matrix material suitable to provide physical and biochemical support to encapsulated cells; development of [ * ] materials beneficial to the encapsulated cells or the host response; provision of safe and effective components and materials-of-manufacture for the implant, including tether, sealing agents, imaging agents, and the like. - CELL BIOLOGY - Procurement, development, and selection of cells capable of sustained intracapsular viability and product release including without limitation, with primary and genetically modified cells techniques for conditioning cells prior to encapsulation; establishment and testing of cell banks or cell pools which meet relevant points to consider and other regulatory requirements; isolation and subsequent manipulation of stem cells, other progenitor cells, and cells derived from stem and progenitor cells; methods for controlling the division rate of cells within capsules; selection of parent cell lines suitable for gene-insertion and subsequent encapsulation; combinations of cells for multiple product release or for other purposes; and methods for analysis of immune consequences of protein release from encapsulated cells. - MOLECULAR BIOLOGY - Engineering of cells capable of stable release of polypeptides in sufficient quantity for therapeutic effect; gene transfer techniques appropriate for transplantable cells; introduction of genetic material which regulates cell growth kinetics or metabolism or sensitivity to killing agents or, more generically, introduction of genetic materials to modulate the up-regulation and/or the down-regulation of target genes. - TRANSGENICS - Creation by transgenic approaches of cells or cell lines * Confidential Treatment Requested <PAGE> 58 suitable for encapsulation which contain foreign genes or a collection of foreign genes. - DEVICE DESIGN - Establishment and validation of implant and implant fabrication parameters such as cell seeding density, intracapsular media, pH, and the like; preparation and validation of the mechanical design of the implant and its accessories; packaging, external media, and the like; development of insertion methods and techniques; development of strengthened implants; sterility assurance. - MANUFACTURING - Establishment and documentation of GMP level procedures for procuring materials, fabricating membranes and subassemblies, encapsulating, filling, testing, holding, releasing, packaging, and shipping implants. Both immunoisolation and viability are relative terms; their requirements will vary with implant site, host-donor combination, and therapeutic intent and the particular forms of encapsulation and related technologies to be used will be chosen based on these requirements. Further examples of some of the techniques used by CTI can be seen in the articles cited below. Encapsulation Technology includes any proprietary knowhow relating to the foregoing including the use of individual elements of the above in combination and inventions and technology covered by CTI Patents. <PAGE> 59 Zurn, A.D., E.E.

Such securities are disposed of pursuant to and in conformity with an effective registration statement filed with the SEC pursuant to the Act or pursuant to Rule 144 of the SEC thereunder; or (b) OPINION OF COUNSEL. Genentech shall have delivered to CTI a written opinion by counsel which is reasonably acceptable to CTI to the effect that the proposed transfer is exempt from the registration and prospectus delivery requirements of the Act. The parties hereto further agree that any certificate evidencing the Shares shall bear the following legend in addition to any legend required to comply with state securities law: THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, HAVE BEEN ACQUIRED FOR INVESTMENT, AND MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM. 8. REGISTRATION RIGHTS. 8.1 CERTAIN DEFINITIONS. As used in this Agreement, the following terms shall have the following respective meanings: "REGISTRABLE SECURITIES" shall mean (i) the Shares and (ii) any Common Stock of CTI issued or issuable with respect to, or in exchange for or in replacement of (a) the Shares, or (b) other securities convertible into or exercisable for Common Stock issued upon any stock split, stock dividend, recapitalization, or similar event; PROVIDED, HOWEVER, that such shares of Common Stock or other securities shall only be treated as Registrable Securities for the purposes of Section 8.2 if and for so long as they have not been (A) sold to or through a broker or dealer or underwriter in a public distribution or a public securities transaction or (B) otherwise transferred to a transferee in whose hands such shares are not (1) restricted securities under the Act or (2) subject to the volume limitations of Rule 144. The term "REGISTER," "REGISTERED" and "REGISTRATION" refer to a registration effected by preparing and filing a registration statement in compliance with the Act, and the declaration or ordering of the effectiveness of such registration statement. "REGISTRATION EXPENSES" shall mean all expenses, except as otherwise stated below, incurred by CTI, in complying with Section 8.2 hereof, including, without limitation, all registration, qualification and filing fees, printing expenses, escrow fees, fees and disbursements of counsel for CTI, blue sky fees and expenses, the expense of any special audits incident to or required by any such registration (but excluding the compensation of -7- <PAGE> 81 regular employees of CTI which shall be paid in any event by CTI) and up to $25,000 for fees and disbursements of one counsel to the holders of CTI's Common Stock participating in such registration. "SELLING EXPENSES" shall mean all underwriting discounts, selling commissions and stock transfer taxes and fees applicable to the securities registered by Genentech and disbursements of counsel to Genentech, if any, in excess of the $25,000 payable to one counsel for the holders of CTI's Common Stock participating in such registration as provided in the definition of the Registration Expenses. 8.2 PIGGYBACK REGISTRATION RIGHTS. (a) NOTICE OF REGISTRATION. If, at any time after the date that is one (1) year from the initial Closing Date, CTI shall determine to register any of its securities, either for its own account or the account of a security holder or holders, other than (i) a registration relating solely to employee benefit plans, or (ii) a registration relating solely to a Rule 145 transaction, CTI will: (i) promptly give Genentech written notice thereof; and (ii) include in such registration (and any related qualification under blue sky laws or other compliance), and in any underwriting involved therein, all the Registrable Securities specified in a written request, made within 20 days after receipt of such written notice from the CTI, by Genentech. (b) UNDERWRITING. If the registration of which CTI gives notice is for a registered public offering involving an underwriting, CTI shall so advise Genentech as a part of the written notice given pursuant to Section 8.2. In such event the right of Genentech to registration pursuant to Section 8.2 shall be conditioned upon Genentech's participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided herein. In such event Genentech (together with all other holders of Common Stock proposing to distribute their securities through such underwriting and CTI) shall enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by CTI. Notwithstanding any other provision of this Section 8.2, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the securities to be distributed through such underwriting. CTI shall so advise all holders of Common Stock distributing their securities through such underwriting of such limitation and the number of shares of Genentech's Registrable Securities that may be included in the registration and underwriting shall be allocated among all such holders in proportion, as nearly as practicable, to the respective amounts of securities eligible to be included in such registration held by such holders at the time of filing the -8- <PAGE> 82 registration statement. To facilitate the allocation of shares in accordance with the above provisions, CTI may round the number of shares allocated to any holder to the nearest 100 shares. If, in the case of a registration initiated pursuant to the exercise by other holders of CTI's Common Stock of so-called "demand" registration rights, the managing underwriter selected for such registration determines that marketing factors require a limitation of the number of shares to be underwritten, Genentech shall have no right to include any shares of its Registrable Securities in such registration unless all shares requested by the holders exercising such "demand" registration rights to be included in such registration are permitted to be included in such registration. If Genentech disapproves of the terms of any such underwriting, Genentech may elect to withdraw therefrom by written notice to CTI and the managing underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration, and shall not be transferred in a public distribution prior to 90 days after the effective date of the registration statement relating thereto, or such other shorter period of time as the underwriters may require. (c) RIGHT TO TERMINATE REGISTRATION. CTI shall have the right to terminate or withdraw any registration initiated by it under this Section 8.2 prior to the effectiveness of such registration whether or not Genentech or any other holder of Common Stock has elected to include securities in such registration. The Registration Expenses of such withdrawn registration shall be borne by CTI in accordance with Section 8.3 hereof. 8.3 EXPENSES OF REGISTRATION. All Registration Expenses incurred in connection with registrations pursuant to this Section 8 shall be borne by CTI. All Selling Expenses relating to securities registered on behalf of Genentech shall be borne by Genentech and holders of securities included in such registration pro rata with CTI and among each other on the basis of the number of shares so registered. 8.4 REPRESENTATIONS OF GENENTECH. Notwithstanding anything to the contrary contained herein, in connection with any underwritten offering, Genentech shall not be required to make any representations or warranties to or agreements with CTI or the underwriters except as relate to Genentech, the Registrable Securities held by it and its intended method of distribution. 8.5 REGISTRATION PROCEDURES. In the case of each registration, qualification or compliance effected by CTI pursuant to this Section 8 in which Genentech participates, CTI will keep Genentech advised in writing as to the initiation of each registration, qualification and compliance and as to the completion thereof. At its expense CTI will: (a) Prepare and file with the SEC a registration statement with respect to such securities and use its best efforts to cause such registration statement to become -9- <PAGE> 83 and remain effective for at least one hundred eighty (180) days or until the distribution described in the Registration Statement has been completed; (b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Act with respect to the disposition of all securities covered by such registration statement; (c) Furnish to Genentech and to the underwriters, if any, such reasonable number of copies of the registration statement, preliminary prospectus, final prospectus and such other documents as Genentech and underwriters may reasonably request in order to facilitate the public offering of such securities; (d) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or "blue sky" laws of such jurisdictions as shall be reasonably requested by Genentech, provided that CTI shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions; (e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Genentech shall also enter into and perform its obligations under such an agreement; (f) Notify Genentech at any time when a prospectus relating thereto is required to be delivered under the Act or the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; (g) As soon as practicable after the effective date of the registration statement, and in any event within 16 months thereafter, have "made generally available to its security holders" (within the meaning of Rule 158 under the Act) an earnings statement (which need not be audited) covering the period of at least twelve months beginning after the effective date of the registration statement and otherwise complying with Section 11(a) of the Act; (h) Furnish, at the request of Genentech, on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Section 8 if being sold through underwriters, or, if such securities are not being sold through underwriters, on the date the registration statement becomes effective, (i) an opinion, dated such date, of the counsel representing CTI for the -10- <PAGE> 84 purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to Genentech and (ii) a letter dated such date, from the independent accountants of CTI, in form and substance as is customarily given by independent accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to Genentech; and (i) Make available for inspection by Genentech and any underwriter participating in any distribution pursuant to such registration statement, and any attorney, accountant or financial advisor retained by Genentech or underwriter, financial and other pertinent records, pertinent corporate documents and properties of CTI, and cause CTI's officers, directors and employees to supply information reasonably requested by Genentech, and any such underwriter, attorney, accountant or financial advisor in connection with such registration statement. (j) Use its best efforts to list the securities covered by such registration statement with any securities exchange on which the Common Stock of CTI is then listed. 8.6 INDEMNIFICATION. (a) CTI will indemnify Genentech, each of its officers, directors, partners, employees and affiliates, and legal counsel, and each person controlling Genentech within the meaning of the Act, with respect to which registration, qualification or compliance has been effected pursuant to this Section 8, and each underwriter for Genentech, if any, and each person who controls any underwriter within the meaning of the Act, against all expenses, claims, losses, damages or liabilities (joint or several) (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened, arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus (preliminary or final), offering circular or other document, or any amendment or supplement thereto, incident to any such registration, qualification or compliance, and any documents filed under state securities laws in connection therewith, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or any violation by CTI of the Act, the Exchange Act, and state securities laws or any rule or regulation promulgated thereunder applicable to CTI in connection with any such registration, qualification or compliance, and CTI will reimburse, as incurred, Genentech, each of its officers, directors, partners, and legal counsel and each person controlling Genentech, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating, preparing or defending any such claim, loss, damage, liability or action, provided that CTI will not -11- <PAGE> 85 be liable in any such case to the extent that any such claim, loss, damage, liability or expense arises out of or is based on any untrue statement or omission or alleged untrue statement or omission, made in reliance upon and in conformity with written information furnished to CTI by an instrument duly executed by Genentech, controlling person or underwriter and stated to be specifically for use therein. (b) Genentech will, if Registrable Securities held by Genentech are included in the securities as to which such registration, qualification or compliance is being effected, indemnify CTI, each of its directors, officers, employees, affiliates and legal counsel, each underwriter, if any, of CTI's securities covered by such a registration statement, each person who controls CTI or such underwriter within the meaning of the Act, and each other holder of CTI's securities, each of their officers, directors, partners, employees, affiliates and legal counsel and each person controlling such holder within the meaning of the Act, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement or alleged untrue statement) of a material fact contained in any such registration statement, prospectus, offering circular or other document, or any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to CTI by an instrument duly executed by Genentech and stated to be specifically for use therein, and will reimburse, as incurred, CTI, such other holders, such directors, officers, persons, underwriters or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action to the extent entitled to indemnification hereunder. Notwithstanding the foregoing, the liability of Genentech under this subsection (b) shall be limited to an amount equal to the net proceeds to Genentech of Registrable Securities sold as contemplated herein, unless such liability resulted from willful misconduct by Genentech. Genentech will not be required to enter into any agreement or undertaking in connection with any registration under this Section 8 providing for any indemnification or contribution on the part of Genentech greater than Genentech's obligations under this Section 8.6. (c) Each party entitled to indemnification under this Section 8.6 (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party, if it so desires, to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld), and the Indemnified Party -12- <PAGE> 86 may participate in such defense at such party's expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 8.4, except and only to the extent that the failure to give such notice is materially prejudicial to an Indemnifying Party's ability to defend such action and provided further, that the Indemnifying Party shall not be entitled to assume the defense for matters as to which there is a conflict of interest or separate and different defenses but shall bear the expense of such defense nevertheless. No Indemnified Party shall consent to the entry of any judgment or enter into any settlement without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld; and in no event shall it be unreasonable so to withhold consent to entry of any judgment or any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. 8.7 INFORMATION BY HOLDER. In the event Genentech elects to include Registrable Securities in any registration, Genentech shall furnish to CTI such information regarding Genentech, the Registrable Securities held by them and the distribution proposed by Genentech as CTI may request in writing and as shall be required in connection with any registration, qualification or compliance referred to in this Section 8. 8.8 RULE 144 REPORTING.
