(a) Janssen agrees to pay Sepracor, for the rights granted to Janssen with respect to OTC Product pursuant to Section 2.1 above, a royalty for OTC Product covered by a Valid Claim of a Sepracor Patent Right sold by or on behalf of Janssen or its Affiliates, Permitted Sublicensees or assigns in the amount of [**] for such OTC Product. Such royalty shall be payable on a country by country basis commencing upon first sale of OTC Product in such country by or on behalf of Janssen or its Affiliates, Permitted Sublicensees or assigns. (b) Each royalty for OTC Product described in Section 4.1(a) shall be payable for sales in a country until the date upon which the last of the Sepracor Patent Rights expire, are abandoned, or are declared no longer valid in such country; provided, however, that after expiration, abandonment, or declaration of invalidity of Sepracor Basic Patent Rights in such country, [**]. On a country-by-country basis, upon expiration of all Sepracor Patent Rights, the license of the Licensed Technology shall be considered fully paid up in such country and no royalties shall be payable to Sepracor for sales of such OTC Product in such country of sale. (c) Janssen agrees to pay Sepracor, for the rights granted to Janssen with respect to Rx Products pursuant to Section 2.1 above, a royalty for Rx Product covered by a Valid Claim of a Sepracor Patent Right sold by or on behalf of Janssen or its Affiliates, Permitted Sublicensees or assigns. Such royalty shall be payable commencing upon first sale in a country of Rx Product by or on behalf of Janssen or its Affiliates, Permitted Sublicensees or assigns. Such royalty for Rx Product shall be: [**] (d) Each royalty for Rx Product described in Section 4.1(c) shall be payable for sales in a country until the date upon which the last of the Sepracor Patent Rights expire, are abandoned, or are declared no longer valid in such country, provided, however, that after expiration, - 8 - <PAGE> Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. abandonment, or declaration of invalidity of Sepracor Basic Patent Rights in such country,[**]. On a country-by-country basis, upon expiration of all Sepracor Patent Rights, the license of the Licensed Technology shall be considered fully paid up in such country and no royalties shall be payable to Sepracor for sales of such Rx Product in such country of sale. (e) Once a royalty becomes payable on a Product in accordance with this Section 4.1, no other royalty shall ever become payable on such Product, regardless of whether and how such Product may subsequently be sold. For the purposes of this Section 4.1, a sale shall be deemed to occur when Janssen, its Affiliates or its Permitted Sublicensees or assigns sends an invoice to an independent third party with respect to such sale. (f) If Janssen pays a royalty on a Product pursuant to this Section 4.1 which has been or is subsequently returned to Janssen, its Affiliates or its Permitted Sublicensees or assigns or if Janssen pays such a royalty on a Product, the sale of which is subsequently cancelled, and any money paid to Janssen is returned to the buyer, the royalty so paid shall be deemed a credit against royalties payable by Janssen for subsequent Payment Periods. If no royalty amounts are payable for a subsequent Payment Period pursuant to this Section 4.1, then the remaining balance of such credits shall be refunded to Janssen within [**] after Sepracor's receipt of Janssen's report for such Payment Period prepared pursuant to Section 4.3 below. 4.2 Timing of Sale. Sales of Product shall be deemed to occur when they are invoiced, or if not invoiced, when Product is delivered to a third party. 4.3 Contents of Janssen's Reports. Janssen shall deliver to Sepracor within [**] after the end of each Payment Period, beginning with the first Payment Period, a written report describing, for the applicable Payment Period: (a) the number and full description of each Product sold by or on behalf of Janssen, its Affiliates and its Permitted Sublicensees and assigns during such Payment Period; - 9 - <PAGE> Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. (b) the Net Sales for Product; and (c) the total royalty due under Section 4.1 above. 4.4 Payments Accompany Janssen's Reports. Each report for a Payment Period required in Section 4.3 above shall be accompanied by full payment to Sepracor of the royalties payable under Section 4.1 above. 4.5 Minimum Royalty. (a) Minimum royalty requirements for the three (3) full calendar years starting after two (2) full calendar years have elapsed following first commercial launch of Rx Product in each of the United States, Japan, the United Kingdom, Germany, Italy, and France, independently, shall be calculated based on [**] for each such country to be submitted by Janssen to Sepracor for the immediately succeeding calendar year. The minimum royalty for each such country shall be [**] for such country multiplied by the average Janssen Net Invoice Price for Rx Products in the relevant country multiplied by the applicable royalty rate in Section 4.1. (b) Janssen's failure to meet the minimum royalty requirements of Section 4.5(a) above shall constitute a basis for Sepracor to convert the exclusive rights and licenses granted to Janssen hereunder with respect to Compound and Product to non-exclusive rights in any such country where the minimum requirements where not reached; provided, however, that before and in lieu of such decision by Sepracor, Janssen may opt to pay the difference between the minimum royalty requirement and the royalty payments actually due for any calendar year within [**] after having received notification from Sepracor that the minimum royalty requirements were not met. 4.6 Payment of Compensation to Sepracor. (a) All payments to Sepracor pursuant to this Agreement shall be made by wire transfer, to Fleet Bank of Massachusetts, 75 State Street, Boston, Massachusetts 02109 (ABA #011000138) to Account No. [**] or such other bank or account as Sepracor may from time to time designate in writing. All such payments shall be made in Dollars. - 10 - <PAGE> Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. (b) Whenever any payment hereunder shall be stated to be due on a day which is not a Business Day, such payment shall be made on the immediately succeeding Business Day. (c) Payments hereunder shall be considered to be made as of the day on which they are received in Sepracor's designated bank or account. (d) If the Janssen Net Invoice Price of any Product for a Payment Period is stated in a currency other than Dollars, then, for the purpose of determining the amount of royalties payable pursuant to Section 4.1 above such Janssen Net Invoice Price shall be converted into Dollars using an average exchange rate between those two currencies during the Payment Period for which such royalties become due, wherein such calculated average exchange rate is calculated as the average of the exchange rates most recently quoted in the Wall Street Journal in New York on or before each of the last days for (i) each month according to the Johnson & Johnson universal calendar in the Payment Period, and (ii) the last month according to the Johnson and Johnson universal calendar in the immediately preceding Payment Period. If no such exchange rates have been quoted in the Wall Street Journal in New York at any time during the twelve (12) month period preceding the date on which such royalties become due, then such Janssen Net Invoice Price shall be converted to Dollars at the average exchange rate used by BankBoston during the Payment Period. (e) All payments due to Sepracor hereunder but not paid by Janssen on the due date thereof shall bear interest (in Dollars) at the rate which is the lesser of: (i) [**]; and (ii) the maximum lawful interest rate permitted under applicable law. Such interest shall accrue on the balance of unpaid amounts from time to time outstanding from the date on which portions of such amounts become due and owing until payment thereof in full. 4.7 Books and Records; Audits.

Asterisks denote omissions. following the calendar year to which they pertain. Janssen shall permit such records and books of account to be examined no more than once each calendar year by an independent certified public accounting form selected by Sepracor and approved by Janssen, which approval shall not unreasonably be withheld. Such examination shall be during normal business hours, upon [**] prior written notice to Janssen, and at Sepracor's expense unless the examination should establish that Janssen's payment of such royalties for the period examined were less than [**] of the royalties which should have been paid, in which case Janssen shall be responsible for the reasonable expenses of such examination. Audits related to Products sold as part of a bundle shall be conducted by an independent certified public accounting form selected by Sepracor and approved by Janssen, which approval shall not unreasonably be withheld which shall disclose to Sepracor only (i) whether the calculated invoice price for such Products is consistent with the terms of this Agreement and Janssen's normal business practices for pharmaceutical products not licensed from a third party and (ii) the specific details concerning any discrepancies. (b) Prompt adjustment shall be made by Janssen to compensate for any errors or omissions disclosed by such examinations. Information obtained during the course of such an examination shall be kept confidential by Sepracor and its agents, except to the extent necessary to enforce Sepracor's rights hereunder. 4.8 Reports and Invoices Conclusively Correct. All reports, invoices and payments not disputed as to correctness by Sepracor within [**] after receipt thereof shall thereafter conclusively be deemed correct for all purposes. 4.9 Third Party Licenses. (a) Janssen shall have the sole discretion to settle claims of third party patent infringement involving Compound or Product and to obtain any patent licenses from a third party Janssen may deem necessary or desirable for manufacture, use or sale of Product.

(c) Except as set forth in Section 4.9(b) above, if Janssen elects to acquire rights under other third party patents which are or would be infringed by use or sale of Product and which Janssen determines are necessary or desirable for commercial success of Product, except for patents relating to controlled release technology, then [**], provided however, that in no event [**]. (d) Except as set forth in Section 4.9(b) above, if Janssen elects to acquire rights under third party patents covering controlled release technology which are or would be infringed by manufacture, use or sale of Product, then [**] provided however, that in no event [**], and further provided that in no event [**]. (e) Notwithstanding anything to the contrary in this Section 4.9, in no event shall royalty payments to Sepracor be [**] pursuant to Subsections (b), (c), and (d) above. 5. INTELLECTUAL PROPERTY RIGHTS 5.1 Filing, Prosecution and Maintenance of Patents (a) Sepracor shall at its own cost diligently file, prosecute and maintain Sepracor Patent Rights including without limitation, any Improvement Patent. Sepracor shall supply Janssen with a copy of the applications as filed, together with notice of its filing date and serial number.

Sepracor shall execute such documents and perform such acts, at Janssen's expense, as may be reasonably necessary to effect an assignment of such Sepracor Patent Right to Janssen. Any such assignment shall be completed in a timely manner to allow Janssen to continue such prosecution or maintenance. Any patents or patent applications so assigned shall not be considered Sepracor Patent Rights and therefore no royalties are due to Sepracor under such patent or patent application. 5.3 Improvement Patents and Other Intellectual Property Rights. All right, title, and interest in any Sepracor Technical Information (including but not limited to inventions, whether patentable or not) shall vest in Sepracor.
