From time-to-time during the Term, Schering will propose Schering Sequences by written notice to the Research Committee, which specifically describes the Schering Sequence being proposed ("Designation"). If RPI has not previously granted a license to a Third Party that would prohibit RPI from granting Schering the licenses contemplated by Section 6.5(b) and 6.5(c) for such Schering Sequence or, unless within fifteen (15) business days from the receipt of such notification by Schering, RPI notifies Schering in writing that it has undertaken a substantial internal program with respect to such Schering Sequence as clearly and convincingly demonstrated in RPI's prior existing written records, such Schering Sequence will become a Designated Schering Sequence and will be listed on Exhibit 5.1. Such Designated Schering Sequence will be added to Exhibit 5.1 hereto provided that there may be no more than [ ] Designated Schering Sequences at any one time. Until Schering notifies RPI it wishes to replace a particular Designated Schering Sequence with another Schering Sequence, RPI shall not grant any licenses to Third Parties, or take any action itself or with or on behalf of Third Parties that would conflict with or be inconsistent with the exclusive licenses granted in Section 6.5(b) and (c) with respect to such Designated Schering Sequences. Schering may Designate no more than [ ] different Designated Schering Sequences during the Term. At any time, pursuant to this Section 5.1, Schering may change the Designated Schering Sequences listed in Exhibit 5.1 by replacing a particular Designated Schering Sequence with another Designated Schering Sequence or by removing and abandoning a Designated 12 22 Schering Sequence upon written notice to RPI. In addition, a Designated Schering Sequence shall be removed from Exhibit 5.1 after Schering has made the product election provided for in Section 8.3 unless Schering elects to maintain such Designated Schering Sequence for a possible future Ribozyme Product against such Designated Schering Sequence as provided in Section 8.3. 5.2 Rights of RPI. Subject to Section 6.8, RPI shall have the right to research, develop, make, have made, and sell products, and to license Third Parties to research, develop, make, have made and sell products, directed against Schering Sequences unless such Schering Sequence is at that time a Designated Schering Sequence or there is a Ribozyme Product then being developed, or sold by Schering directed against such Schering Sequence. VI OWNERSHIP OF TECHNOLOGY; GRANT OF LICENSES; ASSIGNMENT OF RIGHTS TO [ ] FOR [ ] 6.1 Schering Base Technology. Schering owns all rights in Schering Base Technology. 6.2 RPI Base Technology. RPI owns all rights in RPI Base Technology. 6.3 Developed Technology. Schering owns all of Schering solely invented Developed Technology and an undivided one-half interest In jointly invented Developed Technology, and RPI owns all RPI solely invented Developed Technology and an undivided one-half interest in jointly invented Developed Technology. Inventorship is determined by United States patent law. 6.4 Ribozyme Products and Non-Ribozyme Products. Subject to this Agreement, specifically Section 6.6, Schering owns all Ribozyme Products and Non- Ribozyme Products. 6.5 Licenses to Schering. RPI hereby agrees to grant and hereby grants, the following licenses to Schering: (a) [ ] the RPI Base Technology and Developed Technology owned by RPI, to make and use Ribozymes during the Term; (b) [ ] under the RPI Base Technology and by RPI, to make, have made (except as provided in Section 6.5 (d) below), and use Endogenous, and Exogenous Ribozymes with respect to Designated Schering Sequences pursuant to the Research Plan; (c) [ ] under the RPI Base Technology and Developed Technology owned by RPI to make, have made, (except as provided in Section 6.5(d) below), use, sell, offer to sell and import Ribozyme Products and Non-Ribozyme Products; 13 23 (d) subject to Section X "Manufacturing", RPI reserves the right to make, and to have made Exogenous Ribozymes for use pursuant to the Research Plan and Exogenous Ribozyme Products solely for Schering, its Affiliates, or its Sublicensees. 6.6 Schering Grant of [ ]; Research. Subject to this Agreement, and solely for purposes of conducting research pursuant to the Research Plan, during the Term, Schering grants RPI a [ ], in the United States, [ ], to all its rights in Developed Technology and Schering Base Technology necessary for the conduct of such research; provided however, RPI may request that it be able to use certain Developed Technology, whether owned by RPI or Schering, as positive controls in research RPI is conducting with Third Parties. It shall be in Schering's sole discretion whether and to what extent to grant such permissions which shall not be unreasonably withheld. 6.7 Schering Grant of an [ ] to Developed Technology. Schering grants to RPI [ ] on a country-by-country basis to Developed Technology to make, have made, use, sell, offer to sell, and import any Ribozyme or Non- Ribozyme Product upon which Schering terminates development or commercialization as provided in Section 3.3, 3.4 or 9.6 and products against former Designated Schering Sequences which have been removed from Exhibit 5.1 pursuant to Section 5.1 hereof and a nonexclusive right to refer to data in Schering's regulatory filings for such Ribozyme or Non-Ribozyme Product. 6.8 Additional RPI Restrictions. RPI understands that an important basis for Schering to enter into this Agreement and a Purchase Agreement is the right to exploit Developed Technology and not be blocked by licenses granted now or in the future by RPI to Third Parties; therefore, (a) as of the Effective Date, RPI intends not to enter into any agreement or arrangements with Third Parties or grant any licenses to any Third Party with respect to the RPI Base Technology at a time that would provide rights to Third Parties in the making, using, selling, offering to sell or importing Ribozymes for broad use in pathways that could be common intermediary biochemical pathways which are common to present or future Designated Schering Sequences listed on Exhibit 5.1 at that time; (b) RPI has granted licenses to a Third Party with respect to RPI Base Technology that provides such Third Party broad pathway rights or physically contiguous rights that could be or are in common intermediary biochemical pathways which are common to or the same as present to future Designated Schering Sequences or Ribozyme Products. RPI represents that it is attempting to renegotiate such broad pathway license with such Third Party. (c) If RPI does grant such license referred to in Section 6.8 (a), it will notify such Third Parties that it has granted certain licenses to Schering with respect to Designated Schering Sequences and Ribozyme and Non-Ribozyme Products that will be excluded from such licenses to such Third Parties. 6.9 Assignment of Contract Rights to [ ]. RPI hereby hires Schering to conduct research, development and clinical trials of a [ ] for [ ] at Schering's sole cost and sole discretion. If Schering does proceed to conduct clinical trials on a [ ] its duties and rights are governed by RPI's rights in the agreement between RPI and [ ] dated [ ]. RPI agrees that any technology 14 24 created, invented or developed by Schering pursuant to such research, development and clinical trials [ ] shall be owned by Schering subject to the license grant in Section 6.11. 6.10 [ ] means the Endogenous Ribozyme Product mutually agreed to by the Parties which Schering develops through Phase II clinical trials. 6.11 Schering Grant of [ ]. Subject to this Agreement, Schering grants RPI a [ ] to all its rights in the [ ] to make, have made, use, sell, offer to sell and import any [ ] and any Endogenous Ribozyme product directed to any gene found in the [ ] either solely or in conjunction with [ ] pursuant to the [ ] or any RPI agreements with [ ] 6.12 RPI Payments to Schering for any [ ] Ribozyme Product. If Schering researches, develops and conducts clinical testing through Phase II clinical trials of the [ ] then RPI will pay Schering [ ] of all profits it receives on the [ ] for [ ] and [ ] of all profits on all present and future Endogenous Ribozyme products directed towards the [ ] that are sold pursuant to the [ ] or any RPI agreements with [ ] Provided however, if RPI does not receive payments and in lieu receives other value RPI shall provide [ ] of the profits related to such value to Schering. 15 25 VII RESEARCH PAYMENTS AND SECURED LOAN 7.1 Research Payments. (a) Subject to the terms and conditions of this Agreement, and due diligence and good faith efforts of RPI in meeting the goals of the Research Plan, Schering shall pay RPI US$2,000,000 ("Research Payments") per year of the Term at the rate of US$500,000 at the beginning of each quarter. (b) Except for the last quarter of the Term, Research Payments shall be made quarterly at the beginning of each quarter. The last quarterly Research Payment shall be made thirty (30) days after receipt by Schering of the final written research report from RPI. 7.2 Convertible Loan Note. As of the Effective Date Schering will loan funds to RPI pursuant to Exhibit 1 attached to this Agreement. VIII MILESTONE PAYMENTS 8.1 Milestone Payments; Ribozyme and Non-Ribozyme Products. Subject to this Agreement, Schering shall make milestone payments on each Ribozyme and Non-Ribozyme Product as stated below ("Milestone Payments"). No Milestone Payments shall be made on any [ ] Milestone Payments are met and paid only once for each Ribozyme and Non-Ribozyme Product regardless (i) if the Milestone is met more than once in different countries, and (ii) if the same Ribozyme or Non-Ribozyme Product is used for different indications which requires separate regulatory filings and separate and distinct Regulatory Approvals. Except for the First Milestone Payment, if Milestone Payments are made on a Ribozyme or Non-Ribozyme Product and such Ribozyme or Non-Ribozyme Product does not reach the point of First Commercial Sale, then Schering shall have a credit for the total of Milestone Payments applied to any subsequent Milestone Payments due on any Ribozyme or Non-Ribozyme Product directed to the same Gene Target as the Ribozyme or Non-Ribozyme Product that did not reach First Commercial Sale. Furthermore, pursuant to the Purchase Agreement as of the Effective Date, Schering may offset any Milestone Payment except for the First Milestone Payment as provided in the Purchase Agreement. 8.2 First Milestone. Schering shall pay RPI US [ ] upon completion of a relevant animal efficacy model, as discussed by the Research Committee, that in the unanimous opinion of the Research Committee demonstrates that a particular Ribozyme (i) will most likely be a Ribozyme Product with efficacy in man with an acceptable, appropriate therapeutic ratio or (ii) provides sufficient information to enable Schering to design and conduct the research 16 26 and development of a Non-Ribozyme Product with efficacy in man with an acceptable, appropriate therapeutic ratio ("First Milestone Payment"). 8.3 Product Election. Prior to the initiation of GLP toxicity studies for an IND, Schering will send RPI written notice stating whether it will proceed with a Ribozyme Product or Non-Ribozyme Product. If Schering elects a Non-Ribozyme Product, RPI will have the right to research and develop a Ribozyme Product directed at the same sequence as the Schering Non-Ribozyme Product subject to negotiating licenses from Schering to Schering Base Technology unless Schering agrees to pay for such Non- Ribozyme Products the amount of Milestones provided for in Section 8.4 rather than Section 8.5 notwithstanding that it is a Non-Ribozyme Product and maintains the Schering Sequence. In such event, RPI shall not develop a Ribozyme Product directed against such Schering Sequence as long as such Schering Sequence is a Designated Schering Sequence. If Schering elects to proceed with a Ribozyme Product, RPI may not research or develop a Non-Ribozyme Product directed at the same Schering Sequence as the Schering Ribozyme Product. 8.4 Milestone Payments for Ribozyme Products. Subject to this Agreement, Schering shall make additional Milestone Payments on each Ribozyme Product as stated below: (a) [ ] upon initiation of GLP toxicity studies for an IND; (b) [ ] upon IND or equivalent acceptance by a Regulatory Authority; (c) [ ] upon initiation of Phase II Clinical Trials; (d) [ ] upon successful completion of Pivotal Clinical Trials; (e) [ ] upon Regulatory Approval; and (f) [ ] upon First Commercial Sale. 8.5 Milestone Payments; Non-Ribozyme Products. Subject to this Agreement, Schering shall make additional Milestone Payments on each Non-Ribozyme Product as stated below: (a) [ ] upon initiation of GLP toxicity studies for an IND; (b) [ ] upon IND or equivalent acceptance by a Regulatory Authority; (c) [ ] upon initiation of Phase II Clinical Trials; (d) [ ] upon successful completion of Pivotal Clinical Trials; (e) [ ] upon Regulatory Approval; and (f) [ ] upon First Commercial Sale. 17 27 8.6 No Double Milestone Payments. Schering shall pay Milestone Payments once per final Ribozyme or Non-Ribozyme Product. If Schering pays Milestone Payments for a Ribozyme Product or a Non-Ribozyme Product and then develops and sells a Non-Ribozyme Product or a Ribozyme Product for the same clinical indications as the Ribozyme Product, or Non-Ribozyme Product, Schering is not obligated to pay a second set of Milestone Payments. 8.7 Milestone Credits. If a Non-Ribozyme Product is developed first followed by a Ribozyme Product against the same Gene Target, Schering will pay RPI the difference between the Milestones paid for the Non- Ribozyme Product and the Ribozyme Product as such Milestones are achieved. Conversely, if a Ribozyme Product is developed first followed by a Non-Ribozyme Product against the same Gene Target, RPI will provide credit to Schering against future Milestones for such Ribozyme Product, an amount equal to the difference between the Milestones paid for the Ribozyme Product and Milestone payments owed on the Non-Ribozyme Product. IX ROYALTY PAYMENT; THIRD PARTY ROYALTIES; CROSS-ROYALTIES 9.1 Royalty Term. (a) Schering shall pay RPI royalties on Net Sales of Ribozyme Products and Non-Ribozyme Products, on a country-by-country basis. (b) The "Royalty Term" for each Non-Ribozyme Product shall be fifteen (15) years from the date of the First Commercial Sale of each such Non-Ribozyme Product. (c) The "Royalty Term" for each Ribozyme Product shall be from the date of the First Commercial Sale of each such Ribozyme Product, until the later of [ ] from First Commercial Sales of each such Ribozyme Product. Upon the expiration of the patents in RPI Base Technology or Developed Technology owned by RPI which specifically claim such Ribozyme Product on a country-by-country basis, the Royalty shall drop from [ ] as follows: (i) If Annual Net Sales are [ ] (ii) If Annual Net Sales are greater than;] (iii) If Annual Net Sales are greater than [ ] (iv) If Annual Net Sales are greater than [.] 18 28 (b) Paid-Up License. At the end of the Royalty Term for each Ribozyme or Non-Ribozyme Product Schering shall have a [ ] by RPI to make, have made, use, sell, offer to sell or import Ribozyme Products and Non-Ribozyme Products. 9.2 Royalties on Ribozyme Products. Subject to the limitation of payments to be made by Schering pursuant to Section 10.4(b) and (c) during the Royalty Term, Schering shall pay to RPI a royalty of (i) [ ] on Net Sales of each Ribozyme Product ("Royalty"), provided however, if, pursuant to Sections 9.4 and 9.5, Schering is required to pay any Third Party a royalty on a Ribozyme Product or for the use of Ribozyme pursuant to this Agreement and such royalty is paid for a license because of such use or because the Ribozyme Product contains a Ribozyme or because the Ribozyme Product was made using a Ribozyme then one hundred (100%) percent of such royalty shall be deducted from the percentage Royalty paid to RPI; (ii) plus for Exogenous Ribozyme Products manufactured by RPI ("Bonus Royalty"): (a) [ ] if: (i) Annual Net Sales are less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is [ ] (ii) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net is Sales greater than [ ] (b) [ ] if: (i) Annual Net Sales are [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ] but less or equal to [ ] (ii) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering is greater than [ ] but less than, or equal to [ ] (iii) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ] but less than [ ] or (c) [ ] if: (i) Annual Net Sales are less than [ ] and RPI's Transfer Price as a percentage of Net Sales is less than or equal to [ ] 19 29 (ii) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ] but less than or equal to [ ] (iii) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales are greater than [ ] but less than or equal to [ ] (iv) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ], but less than [ ] (d) [ ] if: (i) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is less than or equal to [ ] (ii) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ] but less than or equal to [ ] (iii) Annual Net Sales are greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales are greater than [ ] but less than or equal to [ ] (iv) Annual Net Sales are greater than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ], but less than [ ] (e) [ ] if Annual Net Sales are greater than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ] but less than or equal to [ ] (f) [ ] if: (i) Annual Net Sales greater than [ ] but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is less than or equal to [ ] (ii) Annual Net Sales are greater than [ ], but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ], but less than or equal to [ ] (g) [ ] if: 20 30 (i) Annual Net Sales are greater than [ ], but less than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is less than or equal to [ ] (ii) Annual Net Sales are greater than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is greater than [ ] but less than or equal to [ ] (h) [ ] if Annual Net Sales are greater than [ ] and RPI's Transfer Price to Schering as a percentage of Net Sales is less than or equal to [.] Each Product shall meet its own Net Sales threshold for purposes of calculating the royalties due under this Section 9.2. The Bonus Royalty is applied to the increment of Net Sales to which it applies and not the entire Net Sales amount. The Bonus Royalty referred to in Sections 9.2 (a) through (h) shall not be paid on Net Sales of Exogenous Ribozyme Products during any period there are no issued patents in RPI Base Technology or Developed Technology owned by RPI which specifically claim such Exogenous Ribozyme Product. (i) This chart is intended to be read in conjunction with Section 9.2 (a) through (i). If there is any ambiguity between Section 9.2 (i) and Sections 9.2 (a) through (h), Section 9.2 (a) through (h) controls. [ ] 9.3 Royalties on Non-Ribozyme Products. During the Royalty Term according to Section 9.1(b), Schering shall pay to RPI a royalty of [ ] on Net Sales of each Non-Ribozyme Product. 9.4 RPI Payment of Third Party Royalties. RPI is solely responsible for all fees, payments, royalties, up-front payments concerning the Cech Patents and Ribozyme Technology including but not limited to any royalties to the University of Colorado, University of Colorado Foundation, Inc., CTI, Thomas Cech, Ph.D., and CTI. If such royalties become due and payable, and RPI has failed to make such payments in a timely manner, Schering 21 31 may pay such royalties to Third Parties to which a royalty from RPI is due and credit such payments against any royalties due RPI pursuant to this Agreement. 9.5 Schering's Right to Procure Third Party Licenses. Except as provided in Section 9.4, Schering shall be responsible for procuring such licenses as it deems, in its sole discretion, appropriate for the manufacture, use, marketing, sale or distribution of Ribozyme Products or Non- Ribozyme Products by Schering and its Sublicensees. 9.6 Cross Royalties. In the event Schering pays the First Milestone Payment and then terminates the development of a Ribozyme Product or Non- Ribozyme Product or terminates this Agreement pursuant to Section 18.2(c) or (f), and RPI proceeds with the development and marketing of such Ribozyme or Non-Ribozyme Product, RPI shall pay Schering a royalty of [ ] with respect to Ribozyme Products or [ ] with respect to Non-Ribozyme Products on Net Sales by RPI or any RPI assignee, Sublicensee or any successor in interest of RPI of such Ribozyme or Non-Ribozyme Product that are claimed by one or more issued patents or patent applications in Developed Technology jointly or solely owned by Schering. In all circumstances, RPI shall pay all royalties due pursuant to any Third Party. Royalties will be paid on the Net Sales of each such Ribozyme or Non-Ribozyme Product for a period from the date of the first commercial sale by RPI of such Ribozyme or Non-Ribozyme Product on a country-by-country basis until the last to expire issued Live Claim in the Developed Technology which claims such Ribozyme or Non-Ribozyme Product, or in the case of a Live Claim in a pending patent application in Developed Technology until the earlier of (i) abandonment, cancellation, withdrawal or disclaiming of such Live Claim or (ii) the ten (10) year anniversary of filing such patent application or (iii) if parent of such patent application exists the ten (10) year anniversary of the filing of the earliest such patent application; provided however, if such pending Live Claim should subsequently issue, RPI's royalty obligation shall revive, and RPI shall pay Schering a royalty pursuant to this Section 9.6 ("RPI Royalty Term"). 9.7 Payment of Royalties. (a) Royalty Report. Each Party owing Royalties or royalties to the other Party under this Agreement shall provide a royalty report and, if applicable, a royalty payment to the other Party on a quarterly calendar basis. The report relating to Net Sales within the U.S. shall be provided within ninety (90) days after the end of the calendar quarter to which such report and payment apply and the report relating to Net Sales for countries other than the U.S. shall be provided within one-hundred and twenty (120) days after the end of the calendar quarter to which such report and payment apply. (b) Records Retention. Each Party shall keep, and require any Sublicensee to keep, for a period of not less than seven (7) years, complete and accurate records of all Net Sales of Ribozyme Products and Non-Ribozyme Products. Each Party shall have the right, at its respective sole expense, through a certified public accountant reasonably acceptable to the other Party, and following reasonable notice, to 22 32 examine records of Net Sales and COGS during regular business hours during the Royalty Term or RPI Royalty Term; provided however, that such examination shall not (i) be of records for more than the prior three (3) years, (ii) take place more often than once a year, and (iii) cover any records which date prior to the date of the last examination, and provided further that, such accountants shall report to the auditing Party only as to the accuracy of the royalty statements and payments and the amount of any underpayment or the accuracy of COGS statements. Copies of such reports shall be supplied to the non-auditing Party. In the event the report demonstrates that Schering or RPI has underpaid Royalties or royalties or RPI overstated COGS then Schering or RPI shall promptly pay such Royalties or royalties as the case may be or credit differences caused by overstatement of COGS. In addition, if the amount of underpayment of Royalty or royalties due pursuant to this Agreement or over statement of COGS by [ ] or more than the paying or crediting Party shall also pay interest at the prime rate as stated in the Wall Street Journal under "Money Rates" ("Prime") applied to the amount unpaid from the date due to the date paid. If Schering or RPI has overpaid Royalties or royalties or RPI has overstated COGS, Schering or RPI may credit such overpayments against future Royalties or royalties owed the other Party. If RPI has understated COGS, except as provided in Section 10.4, Schering shall pay the amount of such underpayment. (c) Tax on Royalties. Any tax paid or required to be withheld by a Party for the benefit of the other Party on account of royalties payable to the other Party under this Agreement shall be deducted from the amount of royalties otherwise due. The paying Party shall secure and send to the other Party proof of any such taxes withheld and paid by the paying Party for the benefit of the other Party and shall, at the other Party's request, provide reasonable assistance in recovering said taxes, if possible. (d) Form of Payment. All payments to a Party hereunder shall be made in United States Dollars, for such Party's account, by wire transfer to a bank in the United States designated in writing by such Party; provided that where payments in respect of Net Sales are based on Net Sales in non-U.S. currencies, the amount of Net Sales and any deductions used to calculate Net Sales, if any, shall be converted monthly to United States Dollars at the average of the average daily "bid" and "asked" exchange rates as provided by Reuters (or a different independent wire service providing international spot exchange rates agreed to by the Parties) for the applicable month. 9.8 Reports on Net Sales Exclusions. In the event that Schering or its Sublicensees distributes Ribozyme Products or Non-Ribozyme Products to any entity for research or clinical testing purposes, or indigent or other public support programs, and determines that such distributions shall be excluded from the computation of Net Sales, then Schering shall provide RPI an annual written report on February 15 of each calendar year describing such distribution of all such Ribozyme Products or Non- Ribozyme Products, the purpose for which such Ribozyme Products or Non- Ribozyme Products were distributed, and the 23 33 quantities of Ribozyme Products or Non-Ribozyme Products so distributed in the preceding calendar year. X Manufacturing and Supply 10.1 RPI Right to Manufacture Exogenous Ribozymes. Pursuant to Section 10.5, RPI has the right to manufacture Exogenous Ribozyme Products and shall manufacture Exogenous Ribozymes for research pursuant to the Research Plan. The manufacturing term is the same as the Royalty Term according to Section 9.1(c) on a country-by-country basis (hereinafter referred to as "Manufacturing Term"). 10.2 Schering Right to Manufacture Ribozymes. (i) Schering shall manufacture Endogenous Ribozyme Products, and shall manufacture Endogenous Ribozyme for research pursuant to the Research Plan and, (ii) pursuant to Section 10.5, the backup right to manufacture Exogenous Ribozyme Products. 10.3 Non-Commercial Research and Clinical Supply. Prior to the First Commercial Sale, RPI will manufacture Exogenous Ribozymes for the requirements of Schering for (i) research purposes as ordered by Schering at a price equal to [ ] ("Research Transfer Price") [ ] (ii) clinical purposes as ordered by Schering at a price equal to [ ] per vial ("Clinical Transfer Price"). The Clinical Transfer Price shall be deemed to include the final form of the product and final packaging as described in the IND. 10.4 Commercial Supply. (a) Subject to the terms and conditions of this Agreement, and except to the extent and amounts that it is necessary for Schering or its Sublicensees to maintain levels of production to be a viable backup manufacturer for Exogenous Ribozyme Products, RPI shall supply to Schering, and Schering shall purchase from RPI, all of the worldwide requirements for Exogenous Ribozyme Products of Schering and its Affiliates and Sublicensees at a price equal to [ ] ("Transfer Price"). Such Exogenous Ribozyme Products shall be in final package and final labeling form, and such Transfer Price shall include all raw material, direct labor, overhead, quality control, testing, stability testing, labels, package inserts, cartons, labeling which accompanies the vials, and primary and secondary packaging all as described in the NDA. (b) Provided however, under no circumstances shall such Transfer Price plus Royalty plus Bonus Royalty on Net Sales exceed [ ] (c) The Transfer Price will not exceed [ ] of Schering's Net Sales. If this creates a problem for RPI, the Parties agree to meet to discuss opportunities to further reduce COGS; however, in no event will the Transfer Price exceed [ ] of Schering's Net Sales. (d) If at any time RPI is unable or otherwise fails to provide Exogenous Ribozyme Product in the quantities ordered pursuant to Section 10.10, Schering shall be entitled to obtain that shortfall amount of Exogenous Ribozyme Products from any other supplier or manufacturer as set forth in Section 10.12, and in such case RPI shall just receive the applicable [ ] Royalty on Net Sales. 24 34 10.5 Condition of RPI Becoming Schering's Worldwide Supplier of Exogenous Ribozymes Products. If the conditions set forth in this Section 10.5 have been satisfied, RPI will be Schering's worldwide supplier of Exogenous Ribozyme Products. The conditions precedent to RPI becoming Schering's worldwide supplier of final Exogenous Ribozyme Products are as follows: (a) As of the initiation of Pivotal Clinical Trials for a putative Exogenous Ribozyme Product: RPI shall not be in breach of this Agreement in any material respect (or if it is in breach it shall cure such breach within sixty (60) days of notice thereof); (x) RPI shall have established production facilities which: (i) in the aggregate shall be capable of meeting the supplies for Pivotal Clinical Trials; (ii) shall comprise at least one RPI facility whose capacity is planned to provide Worldwide Target supplies at the time of first Regulatory Approval of each Ribozyme and Non-Ribozyme Product. (y) RPI shall have, (i) during the previous four calendar quarters, timely delivered substantially all amounts of Exogenous Ribozyme Products for testing as to which orders timely placed pursuant hereto were accepted, and (ii) substantially achieved the delivery targets recited in Schering purchase orders. (b) If any of the foregoing conditions have not been satisfied, then, upon written notice from Schering, (i) RPI and Schering will meet at least once to discuss what steps RPI should take to assure Schering that RPI has taken and will take all steps necessary to assure Schering that RPI has the capacity and capability to become Schering's worldwide supplier of Exogenous Ribozyme Products; (ii) the Parties will in good faith discuss such steps and assurances; (iii) if after such discussions, Schering in good faith believes RPI does not have the capacity and capability to become Schering's worldwide supplier of Exogenous Ribozymes, RPI has an additional six (6) months from the meeting referred to in Section (i) of this paragraph to cure the matters set forth in such meeting. If RPI has not cured to Schering's good faith judgment then RPI at Schering's cost will train Schering personnel and shall transfer all manufacturing trade secrets to Schering to ensure that Schering can manufacture Exogenous Ribozyme Products and RPI shall be the backup supplier of Exogenous Ribozyme Products. Schering will thereafter be entitled to have all of its other requirements for Exogenous Ribozyme Products supplied by any other supplier or manufacturer, including Schering, and notwithstanding any other term of this Agreement RPI shall receive as sole compensation on account of Net Sales of Exogenous Ribozyme Products an amount as provided in Section 9.2 of this Agreement. (c) RPI shall advise Schering as soon as practicable if it is unable or does not elect to supply Exogenous Ribozyme Products outside the United States. 10.6 Worldwide Target Defined. The Worldwide Target shall be agreed to between the Parties annually at the date set by Schering (the "Fixing Date"). The "Worldwide Target" shall 25 35 represent a reasonable estimate, based on information available to the Parties as of the Fixing Date, of the total expected worldwide demand for Exogenous Ribozyme Products. Such estimate shall be based upon prior sales history, market demand in excess of current capacity, the size of the potential patient population for approved indications (or indications which are in the final stages of receiving approval) and expected rates of use by such patients, prior and current forecasts (which shall be considered in light of the accuracy of prior forecasts), and such other factors as are reasonably considered in forecasting demand on a long-range basis. The establishment of a Worldwide Target shall not relieve RPI of any best efforts obligation to meet demand in excess of that amount. The calculation of the Worldwide Target shall not include potential sales arising from as-yet unapproved indications, nor shall it be reduced by the mere possibility of restricted sales due to factors such as the actions of a competitor not yet in the market or contemplated governmental actions. 10.7 Ordering Generally. As set forth specifically below, the Parties shall cooperate in the forecasting of demand for Exogenous Ribozyme Product and in providing for worldwide capacity for the manufacture thereof. 10.8 Approval. Upon notification of FDA approval, Schering shall confirm its then-current rolling forecast, and the Parties shall confer as to the possibility of increasing Schering's order in accordance with RPI's manufacturing capacity. The Parties recognize that during the first year after First Commercial Sale there may exist some uncertainties concerning demand for Exogenous Ribozyme Product and agree to meet to confer about these uncertainties on a regular basis, but any modification to the terms hereof shall be only as agreed in writing by the Parties. 10.9 Rolling Forecasts. Upon the initial order for First Commercial Sale of final Exogenous Ribozyme Product, and thereafter on the first business day of each calendar quarter during the term that RPI is manufacturing Exogenous Ribozyme Products for Schering, Schering shall deliver to RPI a non-binding written forecast of the quantities of vials that Schering expects in good faith to order in each of the three consecutive calendar quarters following the quarter for which the most recent order has been placed. Such forecasts shall represent Schering's best estimate of its anticipated orders. At RPI's request Schering shall confer with RPI as to the basis for such forecasts and shall disclose to RPI any underlying data for such forecasts. 10.10 Quarterly Orders. Beginning with the purchase order for the first calendar quarter prior to the First Commercial Sale, Schering shall place written purchase orders for vials or what ever form of the final container for such Exogenous Ribozyme Product (hereinafter referred to as "vials") on a quarterly basis, not less than one hundred eighty (180) days prior to the commencement of the calendar quarter for which the vials are desired. Each purchase order shall specify requested delivery dates and, if appropriate, divide the vials intended for U.S. and non- U.S. markets, and shall be net of (although it shall identify) any vials to be supplied 26 36 by other suppliers as permitted hereunder. Unless otherwise agreed by the Parties in writing, such purchase orders shall specify delivery dates that ratably distribute the delivery of vials among each of the months included in such calendar quarter. No less than 150 days before the commencement of the quarter in which the product is to be delivered, RPI shall, in writing, advise Schering, in good faith, of the number of vials which it accepts for delivery during that period, and Schering shall be entitled to rely on such delivery during that period, and Schering shall be entitled to rely on such advice for purposes of obtaining alternate supplies of Exogenous Ribozyme Products to make up any shortfall in such supplies. Any orders placed hereunder shall be rounded upward, if necessary, to a reasonably whole lot. RPI shall use its best efforts to accept purchase orders consistent with its capacity and to its best efforts to deliver the number of vials that it has accelerated for delivery. To the extent Schering places orders other than such regular quarterly orders, or to the extent that any orders accelerate the estimated delivery schedule, RPI shall use reasonably diligent efforts to supply such quantities so ordered. At the request of either Party, the Parties shall meet and confer in good faith regarding the establishment of a different ordering schedule to take account of market conditions, regulatory approval lag times, or manufacturing time. If, RPI having accepted an order, fails timely to deliver the full amount of such order, then Schering shall (without limiting any other rights hereunder) be reimbursed for the additional costs and expenses reasonably incurred by Schering and directly arising from such failure. 10.11 Reports. RPI will report quarterly to Schering its progress in the manufacture of vials hereunder and RPI shall promptly notify Schering if it appears that RPI will be unable to timely deliver any amounts accepted for delivery. 10.12 Supply Shortfalls; Capacity Planning. (a) At any time during the term of this Agreement Schering shall be entitled to qualify or license any reasonable supplier or manufacturer (including Schering) to manufacture Exogenous Ribozyme Products in any jurisdiction, and shall be entitled to enter into an agreement with such supplier or manufacturer to act as an alternate source of supply of Exogenous Ribozyme Products to Schering in any jurisdiction; provided that Schering shall not order or purchase Exogenous Ribozyme Products from such supplier (other than non-commercial quantities of Exogenous Ribozyme Products used solely for regulatory licensing of such supplier) except under circumstances permitted under this Agreement. (b) If at any time RPI is unable or otherwise falls to supply (or notifies Schering that it cannot supply) Schering with the Exogenous Ribozyme Product for a particular calendar quarter ordered pursuant to Section X, Schering shall be entitled, upon notice to RPI, to obtain the shortage in its requirements for such calendar quarter from any other licensed supplier or manufacturer (including Schering). RPI's sole compensation for Exogenous Ribozyme Product manufactured by such supplier (or Schering) pursuant to this Section shall be the royalty set forth in Section 9.2. 27 37 10.13 Subcontractors. RPI may subcontract with one or more Third Parties for the performance of one or more major processing steps provided that each subcontracting agreement for any major processing steps shall contain the following provisions: (a) in the event of a Change of Control, Schering shall be permitted to assume all of RPI's rights and obligations under such subcontracting agreement; (b) the manufacture of Exogenous Ribozyme Products by each subcontractor shall be approved by the FDA or other appropriate governmental agency; (c) the Exogenous Ribozyme Products or services to be supplied by each subcontractor and the manufacturing process therefor shall comply with all specifications and warranties under this Agreement; and (d) Exogenous Ribozyme Product will be required to be supplied on reasonable commercial terms, including an obligation on the part of each subcontractor to pay damages for breach of its supply obligations, which damages shall include at least the cost of securing alternate supplies. Notwithstanding any such subcontracting agreement, RPI shall remain fully responsible for all of its obligations under this Agreement. 10.14 Manufacturing Procedures. In the manufacturing of the vials, RPI shall adhere to the specifications and shall utilize such additional or modified procedures, facilities, equipment and labeling which may from time-to-time be agreed upon in advance and in writing by the Parties and as required by the FDA or other appropriate governmental regulatory authority. Any amendment to the release specifications shall be by agreement of the Parties not to be unreasonably withheld. RPI, at its sole cost, shall maintain and retain samples required by Current Good Manufacturing Practices as defined in 21 CFR 211 et seq. or any other applicable regulations ("GMP"). In addition RPI will, at its sole cost, select and retain samples of each lot of Exogenous Product and conduct an ongoing stability program as mutually agreed to by the Parties, will maintain all stability records for such period as is required by the FDA or other regulatory agency and furnish Schering with copies of all such records at Schering's request and will undertake any lot-by-lot testing required by the FDA or other regulatory agency, or as requested and paid for by Schering pursuant to budgets agreed in advance. 10.15 Delivery. Promptly upon completion of quality assurance testing by RPI of each lot ordered hereunder, RPI shall notify Schering of the completion thereof and shall provide Schering with appropriate certificates of analysis for such lot. The vials shall comply with all of RPI's warranties under this agreement. Schering shall have final authority to accept the vials from RPI on a lot-by-lot basis, based on whether the lot complies with all of RPI's warranties under this Agreement, and Schering shall have the right to review batch records as well as quality assurance results. If RPI and Schering disagree as to whether a lot has been rightfully rejected then the Parties shall submit the matter to a mutually acceptable third party, such as testing laboratory in the case of a dispute over analysis of the vials. The costs and fees of such third party shall be shared equally by the Parties. Within five business days of notification of completion and provision of the certificates of analysis, unless Schering has properly rejected such lot, Schering shall cause such lot to be removed at Schering's own cost from the premises where such lot was finished. If Schering requires 28 38 longer than such five (5) day period to arrange for removal due to special circumstances, including the reasonable need to review batch records prior to acceptance, Schering shall so notify RPI and the Parties shall discuss in good faith a reasonable extension of such five (5) day period, and prior to delivery RPI shall store Exogenous Ribozyme Product at its own expense. Except for vials intended for distribution in the United States, title to and risk of loss for all vials shall pass to Schering upon delivery to a carrier at RPI. Title to and risk of loss for vials intended for distribution in the United States shall pass to Schering's United States Affiliate upon delivery to a carrier at the RPI site. 10.16 Inspection. Schering may inspect each lot shipped by RPI and shall notify RPI of any non-conformance to specifications (or other proper reason for rejection) within thirty (30) days after receipt of the shipment and the relevant batch records being made available to Schering. Any delivery not rejected by Schering within such thirty (30) days shall be deemed accepted unless Schering informs RPI that Schering's testing or investigation is still under way, in which case the time shall be extended for a reasonable period to allow completion of the testing or investigation; provided however, if a lot is subsequently rejected by the FDA or other applicable regulatory agency (or by Schering in the event the quality control testing of the Exogenous Ribozyme Products necessarily requires more than thirty (30) days), payment for that lot by Schering shall be suspended by Schering, or, if already paid, the next payment to RPI by Schering shall be reduced by crediting the amount Schering had advanced for the non- conforming lot. If such lot is subsequently accepted by the FDA, or other agency, with at least six months remaining prior to the expiration date of such lot, then Schering will, upon Schering's acceptance of such lot, pay RPI according to this Agreement. 10.17 Additional Testing. Schering shall have the right to request any additional testing of the vials (in addition to testing necessary to determine whether to accept the vials) that Schering reasonably believes necessary and, if requested, RPI shall use best efforts to promptly perform such testing and inform Schering of the results; provided however, that all such additional testing shall be at Schering's sole cost and expense, and Schering shall reimburse RPI for its costs (according to agreed budgets) incurred in performing such additional testing within thirty (30) days after RPI submits an invoice for such costs. 10.18 Right to Review Processes. RPI shall maintain all quality assurance manufacturing records and batch production records directly related to the manufacture of Exogenous Ribozyme Products, or copies thereof, as required by FDA or other applicable regulation. Schering's personnel have the right to review and audit compliance with manufacturing specifications during regular business hours at reasonable intervals, and shall have the right to visit and inspect each RPI site at such times as required for the purpose of review of batch records and manufacturing and quality assurance procedures with respect to Exogenous Ribozyme Products, provided that such review or audit does not impede RPI's manufacture and release processes. Schering personnel shall not have access to any records, information, or data concerning other RPI products and Schering personnel having access to any RPI site shall execute reasonable confidentiality agreements to prevent disclosure of such information that may be discovered inadvertently. Schering's personnel may make general inquiries the 29 39 answers to which will be held in confidence by them, concerning such matters as manufacturing scheduling, and equipment cleaning of any other RPI's site to insure that Exogenous Ribozyme Products is being manufactured under GMP. 10.19 Labeling. RPI shall produce all vials in a finished and packaged form, using labels, cartons, package inserts and trade pack shippers in accordance with the format prepared by Schering. Unless the Parties agree otherwise and the law so permits, RPI (as appropriate) shall be identified as the manufacturer on the labels. Schering shall give reasonable advance notice of any label, labeling, or packaging change to enable RPI to switch labels, labeling, or packaging without interrupting RPI's production schedule or incurring unreasonable expense, and unless required by the FDA or other regulatory agency, such changes shall not significantly increase the RPI COGS without RPI's approval, unless Schering agrees to pay for such significant increase. To the extent consistent with FDA or other applicable regulations, and according to Schering's instructions Schering or its Affiliates, shall have its name placed as prominently as possible on the label of the final product. The cost of packaging and labels shall be borne by RPI, provided that if Schering provides packaging or labels for any vials, the actual reduction in the RPI's COGS shall be credited to Schering with respect to such vials against payment to be made upon delivery. 10.20 Investigation of Complaints. Schering shall have the primary right and responsibility to investigate and answer all complaints concerning Exogenous Ribozyme Products. If permitted by law, Schering shall have the primary right and responsibility to report to the FDA or other applicable regulatory agency all complaints and corrective actions with respect to Exogenous Ribozyme Products, but if so required by law, RPI shall perform such reporting. In this regard, Schering will supply RPI with a copy of any completed investigation report as required by GMP as well as any other report needed by RPI to comply with the law. RPI will promptly notify Schering of any adverse events, complaints or problems, or any inquiries made by healthcare providers, or any actual or threatened legal or regulatory action of the FDA or other regulatory agency relating to Exogenous Products hereunder of which RPI has notice. 10.21 FDA Regulation of "Ownership". If it is determined by the FDA that Exogenous Ribozymes are to be regulated as biologics then: (a) Schering shall make all decisions and have regulatory responsibility in respect of the ELA/PLA (Establishment License Application/Product License Application as defined by FDA regulations as amended and foreign equivalents) and (b) the ELA/PLA shall be designate so that Schering or its Affiliate as named as the "Responsible Head" thereof. (b) Schering has sign-off authority with respect to all batch records (including in-process batch records) at Schering's sole cost, risk and expense. (c) If, in the reasonable opinion of Schering based on issued or proposed regulations, or correspondence or statements of the FDA it appears that transferring 30 40 certain responsibilities for Exogenous Ribozyme Products quality control or approval to Schering personnel, including final authority for manufacturing approval of Exogenous Ribozyme Product would materially enhance the ability of Schering to be named in the ELA/PLA as the "Responsible Head", then RPI shall allow Schering, at its sole cost, risk, and expense, to test and release for sale Exogenous Ribozyme Products manufactured at the RPI site(s), and, if it reasonably appears necessary, to place such personnel with such final authority for approval of Exogenous Ribozyme Product in the RPI site(s) to the extent permitted by the Federal Food, Drug and Cosmetic Act and Public Health Act as amended. RPI shall not be liable for any error or omission of such personnel or in such testing, including the erroneous approval of Exogenous Ribozyme Products.
