For each calendar quarter, Janssen shall present binding Purchase Orders for an aggregate quantity of Compound and/or Product which is at least forty percent (40%) of the quantity which Janssen forecasted for such calendar quarter in accordance with Section 3.1(a) above. Janssen shall place each such Purchase Order with Sepracor at least three(3) months before the requested tender date. Each such Purchase Order shall identify the quantity ordered, the requested tender date, and any export/import information required to enable Sepracor to fill such Purchaser Order. Each such Purchase Order shall be deemed an offer to purchase the Compound and/or Product. Unless Janssen is notified in writing to the contrary within seven (7) Business Days after Sepracor receives a Purchase Order, such Purchase Order shall be deemed accepted by Sepracor. In the event of any discrepancy between any Purchase Order and this Agreement, the terms of this Agreement shall govern. (c) Sepracor agrees to undertake the necessary actions at its own expense (including without limitation Good Manufacturing Practices compliance and compliance with the quality control standards set forth in Exhibit 2.5(a) within the time frame set forth in Section 2.5 (a)) to qualify Sepracor or its designated Affiliate or supplier with the FDA and other regulatory agencies as a supplier to Janssen with respect to the Compound and/or Product. Janssen agrees to render Sepracor assistance by giving recommendations with respect to such undertaking. (d) If Janssen elects Sepracor (or a third party manufacturer for Sepracor, as proposed by Sepracor and accepted by Janssen) for the manufacturing of one or more manufacturing steps of Compound and/or Product, and Sepracor agrees to so manufacture, then for the purchase of each quantity of Compound and/or Product, Janssen shall pay Sepracor: -17- <PAGE> 18 Confidential Materials omitted and filed separately with the Securities and Exchange Commission.

Any of such matter reviewed by the JMC on which no consensus can be reached after review as aforesaid shall be resolved by unilateral decision of Janssen or Janssen's Affiliate. Any other matter not to be reviewed by the JMC relating to the promotion and sale of Rx Product in the United States shall be Janssen's sole decision at its own discretion, including but without limitation the time allocation and allocation of Janssen's sales and marketing staff and Janssen's field force to the marketing and selling of Rx Product in the United States subject to the provisions of Section 5.3. 5.3 Co-Promotion. If Janssen exercises its option described in Section 2.3(a) above, then: (a) Provided that Sepracor: (i) shall have established an adequately trained sales force of an adequate professional level, specialization and training consistent with industry standards; and (ii) shall have available a sufficient number of sales representatives to be in a position to give the priorities to the promotion of Rx Product as established in the co-promotion plan, each Party shall co-promote the Rx Products in United States by making presentations to physicians and others, subject however to the conditions set forth herebelow with regard to Sepracor's right to co-promote. (b) No later than three (3) months following NDA submission, Janssen shall provide Sepracor with the co-promotion plan. No later than three (3) months following Sepracor's receipt of the co-promotion plan, Sepracor shall present to Janssen or Janssen's designated Affiliate a hiring and training plan for its sales representatives in view of the co-promotion activities envisaged under this Agreement in accordance with the co-promotion plan. No later than twelve (12) months after NDA filing, Sepracor shall have hired one hundred percent (100%) of the required number of sales representatives (of which at least seventy-five percent (75%) will have pharmaceutical sales experience) and make them available for training jointly with the Janssen field force. (c) The field force allocation, as mentioned in Section 5.2 shall take into account the following principles: (i) for the first two (2) years following launch each Party shall perform a minimum of [**] unless the co-promotion plan provides for fewer calls in which case each Party shall perform pro rata fewer calls; -28- <PAGE> 29 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. (ii) an approximate equal number of high volume prescribers will be allocated to the Sepracor and the Janssen field forces in locations selected to allow efficiency of each Party's field force to be substantially equal, and overall an approximate [**] of the field force activities is envisaged; (iii) optimal effectiveness of the joint field force activities will be a primary objective to be achieved. (d) Both Sepracor and Janssen shall achieve the targets, as mentioned in Section 5.3(c)(i), and Sepracor shall achieve the targets of Sections 5.3(a) and (b). The sales representatives shall be hired on the Parties' or their Affiliates' respective payrolls. Each Party agrees not to actively recruit sales representatives currently in the employ of the other Party. (e) If during the first two (2) years of marketing following the launch date the total number of calls envisaged in the co-promotion plan [**], Sepracor shall be allowed during, but no longer than the first year of marketing, to hire an external contract field force in order to achieve the overall approximate [**] of field force activity. Such external field force shall meet the same qualifications, experience and training requirements as the requirements for the internal Sepracor sales force. At latest after such first year, Sepracor shall hire such number of representatives on the payroll of Sepracor or its Affiliates in order to achieve the overall approximate [**] split of field force activity. (f) In the event Sepracor is, for whatever reason, including Force Majeure delay or default which persists for longer than six (6) months, unable or unwilling to substantially comply with the obligations under this Article 5, and in particular, but without limitation, with the approximate [**] of the field force coverage of the market pursuant to Section 5.3(g) below, Janssen shall have the right: (i) if Sepracor is able and willing to cover at least [**] of the total field force calls, as defined in the co-promotion plan, adapt the profit-sharing and cost-sharing provisions of Section 6.4, both pro rata with the shortage of field force coverage in each Payment Period on the side of Sepracor; or (ii) if Sepracor is unable or unwilling or fails to cover at least [**] of the total field force calls, as defined in the co-promotion plan, terminate the co-promotion activities as envisaged under this Agreement, and simultaneously switch the profit-sharing and cost-sharing as defined in Section 6.4 into a royalty bearing license. Such license shall be subject to the same terms and conditions as in Sections 6.3(c) to (g), 6.5, 6.6, 6.8, 6.9, 6.10, and 6.11. In the foregoing case the royalty -29- <PAGE> 30 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. on sales of Rx Products by Janssen in the United States shall be: (i)[**] and thereafter [**] in case foregoing termination takes place prior to NDA submission in the United States; or (ii)[**] in case termination takes place after NDA submission in the United States. (g) If a Party makes less than [**] of the sales call forecast in the co-promotion plan or actual sales calls in a Payment Period, that Party shall be deemed to have complied with the overall [**] of the field force activity in that Payment Period; however, if in the following Payment Period that Party provides less than [**] of the sales call forecast in the co-promotion plan or actual sales calls for that Payment Period, then (i) if Sepracor is the non-complying Party, the provisions of Section 5.3(f) shall apply in that Payment Period and each subsequent Payment Period, and (ii) if Janssen is the non-complying Party, Janssen shall at its option have the right to (a) continue the profit-sharing and cost-sharing as defined in Section 6.4 irrespective of each Party's relative share of the sales call forecast or actual sales calls, or (b) adapt the profit-sharing and cost-sharing provisions of Section 6.4, both pro rata with the shortage of field force coverage for that and each subsequent Payment Period on the part of Janssen. (h) All sales of the Rx Products in United States shall be booked and invoiced by Janssen consistent with the pricing policy established by Janssen and reviewed from time to time by the JMC pursuant to Section 5.2 above. The Parties shall share profits from sales of Rx Products in United States in accordance with Section 6.4 below. (i) The Rx Products shall be sold in United States with the Trademarks selected by Janssen and tradenames of both Parties displayed in equal prominence in all packaging, advertising, promotional materials, seminars and other promotional and marketing media, subject to applicable laws. (j) The co-promotion activities pursuant to this Section 5.3 shall continue for the commercial life of the Product; provided, however, that the Parties may mutually agree to terminate the co-promotion at any time. The level of co-promotion shall be determined in the co-promotion plan. If active sales promotion through the joint field force is decided to be continued after the -30- <PAGE> 31 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. second anniversary of Rx Product launch in the United States, then the principles of Sections 5.3(c) (ii) and (iii) shall continue to apply to sales force allocation. 5.4 If Sepracor exercises Option B described in Section 2.3(d) or the co- promotion is terminated pursuant to Section 5.3(f)(ii) after NDA submission, both Janssen and Sepracor may still agree that Sepracor will participate in the promotion and selling efforts of Rx Product in the United States by providing sales calls on a fee for service basis consistent with current industry standards for rental sales force. Such promotion and selling efforts will be agreed in a separate co-promotion agreement. 6. COMPENSATION PAYABLE TO SEPRACOR 6.1 Pre-Option Clinical Testing Expenses. (a) For the rights and options granted hereunder, Janssen shall pay Sepracor [**] of the expenses incurred by Sepracor in conducting and analyzing the results of the Pre-Option Clinical Testing. (b) Sepracor shall submit a statement to Janssen on a monthly basis at the end of each month of the Johnson & Johnson universal calendar as to the aforesaid expenses in Section 6.1(a) actually incurred by Sepracor, together with an invoice for [**] of such expenses. Janssen shall pay such invoices within thirty (30) days of the end of the calendar month during which the invoice was issued to Janssen. (c) These expenses are subject to the same record-keeping and examination requirements as apply to Sepracor's manufacturing costs under Section 3.1(f) above. 6.2 Funding for Research and Development Efforts. (a) Subject to Janssen exercising the option pursuant to Section 2.3(a), Janssen and Sepracor each agrees to pay [**] of the R&D Expenses incurred in accordance with the R&D Plan, even for studies consented to by Janssen and started by Sepracor before the option is exercised; provided, however that Janssen's obligation to pay [**] of the expenses of such studies shall only become effective upon exercising the option pursuant to Section 2.3(a) whereupon Janssen shall pay Sepracor [**] of the R&D Expenses incurred prior to Janssen's exercise of the option for studies started before such exercise. Moreover, Sepracor and Janssen shall each -31- <PAGE> 32 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. carry [**] of expenses incurred in connection with any studies additional to the Pre-Option Clinical Testing and other than covered by the R&D Plan agreed to by the Parties and commenced prior to exercise or lapse of the option. In no event, however, shall Janssen be required to pay any amount for repetition of all or part of any study which was performed by Sepracor without Janssen's review and consent prior to the date of this Agreement and which the FDA requires to be repeated in whole or in part for submission of the NDA for Rx Product. If Sepracor is required by the FDA to repeat such a study prior to the lapse or exercise of Janssen's option under Section 2.3(a), the option period set forth in Section 2.3(b) shall not start to run until such study is completed and the results of the study have been made available to Janssen.

The following shall apply: (i) each Party shall maintain a separate general ledger account for the purposes of recording all of the R&D Expenses which it incurs during the term of this Agreement. (ii) within thirty (30) days after the end of each Payment Period, the Parties shall exchange information detailing the accounts described in Section 6.2(a) above during the Payment Period. If one Party has recorded more than the other in said Payment Period, that Party shall submit an invoice to the other Party for [**] of the difference between the amounts recorded by the respective Parties. The other Party shall pay the full amount of each such invoice within thirty (30) days of the end of the calendar month during which the invoice was issued. (iii) R&D Expenses which are subject to reimbursement in accordance with Section 6.2(a) above are subject to the same record-keeping and examination requirements as apply to Sepracor's manufacturing costs under Section 3.1(f) above. (b) Janssen shall develop OTC Product, and Rx Products outside United States, at its own cost and expense. 6.3 Royalties. (a) Janssen agrees to pay Sepracor, for the rights granted to Janssen with respect to OTC Products pursuant to Section 2.1 above, a royalty for each and every OTC Product sold by or on behalf of Janssen or its Affiliates, -32- <PAGE> 33 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. Permitted Sublicensees or assigns (excluding returns). Such royalty for each OTC Product shall be [**] of the Janssen Net Invoice Price for each such OTC Product. (b) If Janssen exercises its option described in Section 2.2(a) above, then Janssen agrees to pay Sepracor, for the rights granted to Janssen with respect to Rx Products outside United States pursuant to Section 2.1 above, a royalty for each and every Rx Product sold by or on behalf of Janssen or its Affiliates, Permitted Sublicensees or assigns outside United States (excluding returns). Such royalty for each Rx Product shall be [**] of the Janssen Net Invoice Price for each such Rx Product for sales made prior to [**] , and [**] of the Janssen Net Invoice Price for each such Rx Product for sales made thereafter. (c) RESERVED. (d) Once a royalty becomes payable on a Product in accordance with this Section 6.3, 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 6.3, 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. (e) Janssen shall not be required to pay any royalty with respect to any Compound or Product sold to Sepracor or any of its Affiliates, Permitted Sublicensees or assigns of Sepracor. (f) Each royalty for Rx Product described in Section 6.3(b) shall be deemed to be payable for sales in a country until the later of the following dates: (i) if the Rx Product is covered by a Valid Claim of a patent or patent application of the Sepracor Patent Rights as listed in Exhibit 1.31(a) hereto in that country, until the date upon which such patents or patent applications expire, are abandoned, or are declared no longer valid in any such country; (ii) the date which is ten (10) years after the first commercial sale of such Rx Product by Janssen or its Permitted Sublicensees or assigns in such country of sale; (iii) with respect to (i) and (ii) above, thereafter the license of the Licensed Technology shall be considered fully paid up and no royalties shall be payable to Sepracor for sales of such Rx Product in such country of sale; and -33- <PAGE> 34 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. (iv) with respect to (i) and (ii) above, the royalty shall be reduced by [**] in such country(ies) if and when a third party introduces a generic version of Rx Product in such country(ies). (g) If Janssen pays a royalty on a Product pursuant to this Section 6.3 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 royalties amounts are payable for a subsequent Payment Period pursuant to this Section 6.3, then the remaining balance of such credits shall be refunded to Janssen within thirty (30) days after Sepracor's receipt of Janssen's report for such Payment Period prepared pursuant to Section 6.5 below. (h) Each royalty for OTC Product described in Section 6.3(a) shall be deemed to be payable for sales in a country until the later of the following dates: (i) if the OTC Product is covered by a Valid Claim of a patent or patent application of the Sepracor Patent Rights as listed in Exhibit 1.31(a) hereto in that country, until the date upon which such patents or patent applications expire, are abandoned, or are declared no longer valid in any such country; (ii) the date which is ten (10) years after the first commercial sale of such OTC Product by Janssen, its Affiliates or Permitted Sublicensees or assigns in such country of sale; (iii) with respect to (i) and (ii) above, thereafter such royalties shall be reduced by [**]; provided, however, that if a third party introduces an OTC Product in such country then no further royalties shall be payable on sales of OTC Products in such country after the later of such date and the date of introduction of the third party OTC Product in such country. 6.4 Profit-Sharing and Cost Sharing for Co-Promotion of Rx Products in United States. (a) Subject to Janssen exercising the option pursuant to Section 2.3(a), Janssen and Sepracor each agree to pay [**] of the Marketing and Technology Costs and Costs of Goods Sold. Therefore, for each Payment Period, Janssen shall pay an amount to Sepracor so that Sepracor will receive [**] of the Operating Income -34- <PAGE> 35 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. for such Payment Period; provided, however, that to the extent Operating Income is less than [**] for such Payment Period, Sepracor shall pay an amount to Janssen which is equal to [**] of the amount by which Operating Income for such Payment Period is less than [**]. (b) Sales of Rx Products in United States shall be deemed to occur when they are invoiced, or if not invoiced, when delivered to a third party. (c) RESERVED. 6.5 Contents of Janssen's Reports. Janssen shall deliver to Sepracor within thirty (30) days 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; (b) with respect to Rx Products sold outside the United States and OTC Products, no matter where they are sold: (i) the Net Sales for Product, being Janssen Net Invoice Prices multiplied by the volume of Products sold; (ii) the total royalty due on such payments under Section 6.3 above; and (c) if Janssen exercises its option described in Section 2.3 (a) above, then with respect to Rx Products sold in United States: (i) the Operating Income for such Payment Period; and (ii) [**] share of Operating Income, or [**] of the amount by which Operating Income is less than [**], as the case may be. 6.6 Payments Accompany Janssen's Reports. Each report for a Payment Period required in Section 6.5 above shall be accompanied by full payment to Sepracor of the royalties and other amounts payable under Sections 6.3 and 6.4 above. -35- <PAGE> 36 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. 6.7 Minimum Royalty. (a) If Janssen exercises the option described in Section 2.2(a) above, 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 Japan, the United Kingdom, Germany, Italy, and France, independently, shall be calculated based on [**] of a non-binding forecast 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 [**] of the non-binding forecasted volume for such country multiplied by the average Janssen Net Invoice Price for Rx Products in the relevant country multiplied by the royalty rate in Section 6.3(b). If Sepracor exercises one of the options set forth in Section 2.3(d), or if the co-promotion rights pursuant to Section 5.3 and profit-sharing and cost-sharing envisaged in Section 6.4 are converted to a royalty bearing license to Rx Product in the United States pursuant to any provision of this Agreement, 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 the United States shall be calculated based on [**] of a non-binding forecast for the United States to be submitted by Janssen to Sepracor for the immediately succeeding calendar year. The minimum royalty for the United States shall be [**] of the non-binding forecasted volume for the United States multiplied by the average Janssen Net Invoice Price for Rx Products in the United States multiplied by the royalty rate in Section 2.3(d), Section 5.3(f), Section 6.12 or Section 13.1, as appropriate.

(c) Minimum royalty requirements for Sepracor for the three (3) full calendar years starting after two (2) full calendar years have elapsed following first commercial launch of Rx Product for each of the countries of the Rx Countries for which Janssen has not exercised the option pursuant to Section 2.2(a) shall be calculated based on [**] of the non-binding forecast submitted by Sepracor to Janssen -36- <PAGE> 37 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. for the immediately succeeding calendar year. The minimum royalty shall be [**] of the non-binding forecasted volume for a relevant Rx Country multiplied by the average Sepracor Net Invoice Price for Rx Product for the relevant Rx Country multiplied by the royalty rate of Section 7.1(a). If Janssen fails to exercise the option pursuant to Section 2.3(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 the United States shall be calculated based on [**] of a non-binding forecast for the United States submitted by Sepracor to Janssen for the immediately succeeding calendar year. The minimum royalty shall be [**] of the non-binding forecasted volume for the United States multiplied by the average Sepracor Net Invoice Price for Rx Product in the United States multiplied by the royalty rate of Section 7.1(a). (d) Sepracor's [**] in Section 6.7(c) above shall constitute a basis for Janssen to [**] granted to Sepracor hereunder with respect to Rx Products to non-exclusive rights in any such country where the minimum requirements were not reached; provided, however, that before and in lieu of such decision by Janssen, Sepracor may [**] between the minimum royalty requirement and the royalty payments actually due for any calendar year within thirty (30) days after having received notification from Janssen that the [**] and failing this, Janssen shall then have the right, among other things, to grant additional licenses in the Field with respect to the Rx Products and (both for itself and its Affiliates) to make, have made, use and sell the Rx Products in such country. 6.8 Payment of Compensation to Sepracor. (a) All payments under Sections 6.1, 6.2, 6.3, 6.4 and 6.7 above shall be made by wire transfer, to Fleet Bank of Massachusetts, 75 State Street, Boston, Massachusetts 02109 (ABA #011000138) to Account No. 9372882375 or such other bank or account as Sepracor may from time to time designate in writing. All such payments shall be made in Dollars. (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 Net Invoice Price of any Product or any part of Revenue for a Payment Period is stated in a currency other than Dollars, then, for the -37- <PAGE> 38 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. purpose of determining the amount of royalties payable pursuant to Section 6.3 above and Sepracor's share of Operating Income which is payable pursuant to Section 6.4 above, such Net Invoice Price or part of Revenue, as the case may be, shall be converted into Dollars using an average exchange rate between those two currencies during the Payment Period for which such royalties or share of Operating Income become due pursuant to Section 6.6 above, 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 or share of Operating Income become due, then such Net Invoice Price or part of Revenue 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. 6.9 Books and Records; Audits. (a) Janssen shall keep and maintain, and shall cause its Permitted Sublicensees and assigns to keep and maintain, complete and accurate records and books of account (including without limitation customer call reports and other information required to confirm the accuracy of Janssen's methodology for allocating the time of its sales staff between selling the Rx Product in the United States and such staff's other responsibilities) in sufficient detail and form so as to enable amounts payable under Sections 6.3 and 6.4 above to be determined. Such records and books of account shall be maintained for a period of no less than two (2) years following the calendar year to which they pertain. Janssen shall permit such records and books of account to be examined by Sepracor or Sepracor's duly appointed agent(s) no more than once each calendar year, to the extent necessary for Sepracor to verify such amounts. Such examination shall be during normal business hours, upon twenty (20) days' prior written notice to Janssen, and at Sepracor's expense unless the examination should establish that Janssen's payment of such royalties (and payment of Sepracor's share of Operating Income, in the case of Section 6.5 above) for the period examined were less than ninety-five percent (95%) of the -38- <PAGE> 39 royalties and share 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 accounting firm which shall disclose to Sepracor only 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 the specific details concerning any discrepancies. (b) If Janssen exercises its option described in Section 2.3 above, then Sepracor shall keep and maintain complete and accurate records and books of account (including without limitation customer call reports and other information required to confirm the accuracy of Sepracor's methodology for allocating the time of its sales staff between selling the Rx Product in the United Stated and such staff's other responsibilities) in sufficient detail and form so as to enable the amounts of Marketing and Technology Costs incurred by Sepracor with respect to Rx Products sold in United States to be determined. Such records and books of account shall be maintained for a period of no less than two (2) years following the calendar year to which they pertain. Sepracor shall permit such records and books of account to be examined by Janssen or Janssen's duly appointed agent(s) no more than once each calendar year, to the extent necessary for Janssen to verify such amounts. Such examination shall be during normal business hours, upon twenty (20) days' prior written notice to Sepracor, and at Janssen's expense unless the examination should establish that Sepracor's claims with respect to such Marketing and Technology Costs for the period examined were more than one hundred five percent (105%) of the Marketing and Technology Costs which were actually incurred for such period, in which case Sepracor shall be responsible for the reasonable expenses of such examination. (c) Prompt adjustment shall be made by the proper Party 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 the examining Party and its agents, except to the extent necessary to enforce the examining Party's rights hereunder. 6.10 Reports and Invoices Conclusively Correct. All reports, invoices and payments not disputed as to correctness by the receiving Party within three (3) years after receipt thereof shall thereafter conclusively be deemed correct for all purposes. 6.11 Issuance of Patents. Notwithstanding anything contained in this Agreement to the contrary, in the event a patent is issued prior to expiration or termination of this Agreement with respect to any part of the Technical Information of Sepracor, such patent shall be deemed to be Sepracor Patent Rights and the -39- <PAGE> 40 Confidential Materials omitted and filed separately with the Securities and Exchange Commission. Asterisks denote omissions. royalties and other amounts payable hereunder shall not be increased on those Products which embody or rely on such patent. 6.12 In the event Sepracor is, for whatever reason, including Force Majeure delay or default which persists for longer than one (1) month, unable or unwilling to comply with its obligation to fund its share of R&D Expenses or Marketing and Technology Costs, Janssen has the option to either (A) terminate the co-promotion activities and cost-sharing as envisaged under this Agreement and to simultaneously switch the profit-sharing and cost sharing as defined in Section 6.4 into a royalty bearing exclusive license in the Field to Janssen or (B) terminate the co-promotion activities and cost-sharing as envisaged under this Agreement and to maintain the profit-sharing as defined in Section 6.4 as described hereunder. Such license (if Janssen chooses Option A) shall be subject to the same terms and conditions as in Sections 6.3(c) to (g), 6.5, 6.6, 6.8, 6.9, 6.10 and 6.11. In the foregoing case the royalty on sales of Rx Products by Janssen in the United States shall be (i) either [**] and thereafter [**] in case foregoing termination takes place prior to NDA submission in the United States or (ii)[**] in case the foregoing termination takes place after NDA submission in the United States. If Janssen chooses Option B, i.e., to maintain the profit-sharing, all amounts of R&D Expenses and/or Marketing and Technology Costs which are or have become due (to be increased with interest in accordance with Section 7.4(e)) from Sepracor at the time Janssen selects Option B in accordance with this Agreement and which have been assumed by Janssen following Janssen's choice of Option B hereunder shall be deducted from any amounts due to Sepracor pursuant to Section 6.4 hereof. 7. COMPENSATION PAYABLE TO JANSSEN 7.1 Royalties Paid to Janssen. (a) If Janssen does not exercise its option described in Section 2.2 above, or if Janssen does exercise such option but has not retained the rights granted pursuant thereto, Sepracor agrees to pay Janssen, for the rights granted to Sepracor with respect to Rx Products pursuant to Sections 2.1(c) and (d) above, a royalty for each and every Rx Product sold by or on behalf of Sepracor, its Affiliates or its Permitted Sublicensees or assigns outside the United States (excluding returns).

(d) Sepracor shall not be required to pay any royalty with respect to any Rx Product sold to Janssen or any of its Affiliates. (e) Each royalty described in this Section 7.1 shall be deemed to be payable for sales in a country until the later of the following dates: (i) if the Rx Product is covered by a Valid Claim of a patent or patent application of the Janssen Patent Rights as listed in Exhibit 1.10(a) hereto in that country, until the date upon which such patents or patent applications expire, are abandoned, or are declared no longer valid in any such country; (ii) the date which is ten (10) years after the first commercial sale of such Rx Product by Sepracor, its Affiliates or its Permitted Sublicensees or assigns in such country of sale; (iii) with respect to (i) and (ii) above, thereafter the license of the Licensed Technology shall be considered fully paid up and no royalties shall be payable to Janssen for sales of such Rx Product in such country of sale. (iv) with respect to (i) and (ii) above, the royalty shall be reduced by [**] in such country(ies) if and when a third party introduces a generic version of Rx Product in such country(ies). (f) If Sepracor pays a royalty on an Rx Product pursuant to this Section 7.1 which has been or is subsequently returned to Sepracor, its Affiliates or its Permitted Sublicensees or assigns or if Sepracor pays such a royalty on a Product, the sale of which is subsequently cancelled, and any money paid to Sepracor is returned to the buyer, the royalty so paid shall be deemed a credit against royalties payable by Sepracor for subsequent Payment Periods. If no royalties amounts are -41- <PAGE> 42 payable for a subsequent Payment Period pursuant to this Section 7.1, then the remaining balance of such credits shall be refunded to Sepracor within thirty (30) days after Janssen's receipt of Sepracor's report for such Payment Period prepared pursuant to Section 7.2 below. 7.2 Contents of Sepracor's Reports. Sepracor shall deliver to Janssen within thirty (30) days after the end of each Payment Period, beginning with the Payment Period during which Janssen's option under Section 2.2 or 2.3 above lapses or Janssen otherwise waives its right to exercise either such option, a written report describing, for the applicable Payment Period: (a) if Janssen does not exercise its option described in Section 2.2 above, the number and full description of each Rx Product sold by or on behalf of Sepracor, its Affiliates and its Permitted Sublicensees and assigns outside the United States during such Payment Period; (b) if Janssen does not exercise its option described in Section 2.3 above, the number and full description of each Rx Product sold by or on behalf of Sepracor, its Affiliates and its Permitted Sublicensees and assigns in the United States during such Payment Period; (c) with respect to Rx Products reported pursuant to Sections 7.2(a) and/or (b) above: (i) the Net Sales for Product being Sepracor Net Invoice Price multiplied by the volume of Rx Product sold; (ii) the total royalty due on such payments under Section 7.1 above. 7.3 Payments Accompany Sepracor's Reports.

Asterisks denote omissions. (c) Payments hereunder shall be considered to be made as of the day on which they are received in Janssen's designated bank or account. (d) If the Sepracor Net Invoice Price of any Rx Product is stated in a currency other than Dollars, then, for the purpose of determining the amount of royalties payable pursuant to Section 7.1 above, such Sepracor Net Invoice Price shall be converted into Dollars using a calculated average exchange rate between those two currencies during the Payment Period for which such royalties become due pursuant to Section 7.3 above, 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 & Johnson universal calendar in the immediately preceding Payment Period. If no such exchange rate has 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 Net Invoice Price or part of Revenue shall be converted to Dollars at the average exchange rate used by BankBoston during the Payment Period. (e) All payments due to Janssen hereunder but not paid by Sepracor 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. 7.5 Sepracor Books and Records; Audits.

Sepracor shall permit such records and books of account to be examined by Janssen or Janssen's duly appointed agent(s) no more than once each calendar year, to the extent necessary for Janssen to verify such amounts. Such examination shall be during normal business hours, upon twenty (20) days' prior written notice to Sepracor, and at Janssen's expense unless the examination should establish that Sepracor's payment of such royalties for the period examined were less than ninety-five percent (95%) of the royalties which should have -43- <PAGE> 44 been paid, in which case Sepracor 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 accounting firm which shall disclose to Janssen only whether the calculated invoice price for such Products is consistent with the terms of this Agreement and Sepracor's normal business practices for pharmaceutical products not licensed from a third party and the specific details concerning any discrepancies. (b) Prompt adjustment shall be made by the proper Party 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 Janssen and its agents, except to the extent necessary to enforce Janssen's rights hereunder. 7.6 Sepracor Reports and Invoices Conclusively Correct. All reports, invoices and payments not disputed as to correctness by Janssen within three (3) years after receipt thereof shall thereafter conclusively be deemed correct for all purposes. 7.7 Issuance of Patents. Notwithstanding anything contained in this Agreement to the contrary, in the event a patent is issued prior to expiration or termination of this Agreement with respect to any part of the Technical Information of Janssen, such patent shall be deemed to be Janssen Patent Rights and the royalties and other amounts payable hereunder shall not be increased on those Products which embody or rely on such patent. 8.

Costs of drafting, filing, and maintenance of jointly owned patents and patent applications, and defense of jointly owned intellectual property rights, shall be borne equally. Each Party shall provide to the other Party, as to those jointly owned applications which it is filing, copies of all patent applications prior to filing, for the purpose of obtaining comments and advice from the other Party's patent advisors and the other Party's approval to so file which approval shall be provided within a reasonable time. Upon the other Party's approval, such Party shall be free to file said patent applications. Such Party shall also consult with the other Party on the prosecution of said applications and provide to such Party copies of all substantive documents relating to the prosecution of said applications. If a first Party wishes to abandon a jointly owned patent or patent application or to refrain from filing such patent application or defending such patent, the other Party shall have the right to take contrary action at its own expense, whereupon the first Party shall assign all its right, title, and interest in such patent or application to the other Party. (d) Each Party hereto shall, at the request of the other Party, both during and after the term of this Agreement, execute such documents and render such assistance as may be appropriate to enable the other Party to maintain or obtain registrations of patents or intellectual property rights in any jurisdiction in accordance with this Section 8.2.
