If the Steering Committee determines (whether by consensus or through the use of an Expert as provided in Section 3.5.4) that such obligations should be modified or terminated, then Kos’ obligations shall resume at such modified levels, if any.

5.4 Responsibilities of Jagotec under the Commercialization Program. Jagotec shall be responsible for facilitating discussions between Jagotec’s Licensees and Kos for Kos and such Licensees to share certain information relating to their respective commercialization plans (consistent with the determination of the Commercialization Committee as provided in Section 3.3.3) for the Product in the Field so that a consistent global commercialization plan for the Product in the Field can be developed as between Kos and such Licensees.

6.4 Royalty Reductions.

6.4.1 If either Party deems it necessary to obtain a license, or other rights to any Blocking Patents with respect to the Product, such Party shall notify the other Party.

(a) If the other Party agrees, then the Parties shall discuss in good faith the procedure by which the Parties will seek to obtain such license or other rights. The costs paid to a Third Party (including royalties upfront, initial, milestone and periodic payments, court awarded damages and settlement payments) associated with obtaining such license or other rights shall be **** by the Parties in the following manner: all costs shall be paid by **** to such Third Party, provided that **** of such costs shall be reimbursed to **** by crediting at any one time (until such time as **** has recovered such costs) up to **** of, at **** election: (i) any **** upon obtaining the first Registration of the Product as provided therein; (ii) any ****; and/or (iii) any ****; and **** may carry forward any unreimbursed amount to be credited against future payments until the full fifty percent (50%) of such costs (including royalties upfront, initial, milestone and periodic payments, court awarded damages and settlement payments) paid by *** have been fully recaptured by ****. Notwithstanding the foregoing, the aggregate costs recaptured pursuant to this Section 6.4.1(a) and Section 4.2.2(c) shall in no event exceed **** of any payment due to ****.

(b) If the other Party disagrees with the initial assessment, the Parties shall obtain an opinion of independent patent counsel reasonably acceptable to both Parties to make such determination, and such opinion shall be binding on both Parties. In the event that such opinion indicates that there is a Blocking Patent, then the Parties shall immediately proceed in the manner provided in Section 6.4.1(a). The Party making the incorrect assessment shall be solely responsible for all attorney fees incurred in connection with this Section 6.4.1(b).

6.4.2 If a Generic Product is being marketed and sold in the Territory, for any **** in which sales of the Product measured on a number of units sold basis are at least **** lower than the average number of units of Product sold by Kos and its Affiliates during the **** prior to the launch of such Generic Product the royalty rate with respect to Net Sales in such **** shall be **** of the royalty rate which would otherwise apply to such Net Sales during such **** as set forth in Section 6.3. For purposes of clarity, the foregoing royalty reduction shall not apply to any **** in which the number of units of Product sold by Kos and its Affiliates are not at least **** lower than the average number of units of Product sold in the **** prior to launch of such Generic Product, as described above.

6.4.3 Upon the expiration of the term of this Agreement pursuant to Section 13.1, if the Parties agree in writing to extend the term of this Agreement pursuant to Section 13.2, and provided that a Generic Product is not being marketed and sold in the Territory, the

royalty rate with respect to Net Sales during such extended term shall be **** of the royalty rate which would otherwise apply to such Net Sales as set forth in Section 6.3. Notwithstanding the foregoing, in the event that a Generic Product is being marketed and sold in the Territory in the manner set forth in Section 6.4.2 and the Parties have agreed to extend the term of this Agreement pursuant to Section 13.2, the royalty rate for Net Sales specified in Section 6.3 which would otherwise apply to Net Sales during the applicable Calendar Quarter shall be reduced to ****.

6.4.4 For the sake of clarity, in no event shall the royalty rate for Net Sales during any period be less than ****.

If Kos or any of its Affiliates that distribute the Product, sells any Product to a customer who also purchases other products from such entity, Kos agrees that if it bundles or includes any Product as part of any multiple product offering in a manner that is reasonably likely to disadvantage the Product in order to benefit sales or prices of other products offered for sale by Kos or its Affiliates, then for purposes of calculating the payments due hereunder, the Net Sales shall be adjusted to reverse any discount which was given to a customer that was in excess of customary discounts for the Product (or, in the absence of relevant data for the Product, other similar products under similar market conditions), if such discount was given in order to gain or maintain sales of other products.

7. Payments and Reports.

7.1 Payments.

7.1.1 Beginning with the Calendar Quarter in which the First Commercial Sale of the Product is made in the Territory, and for each Calendar Quarter thereafter, (i) royalty payments shall be made to Jagotec pursuant to Section 6.3 within **** days following the end of each such Calendar Quarter for the first, second and third Calendar Quarters in each Calendar Year; and (ii) royalty payments pursuant to Section 6.3 for the fourth Calendar Quarter of each Calendar Year shall be made to Jagotec within **** days following the end of each such Calendar Quarter; provided, however, that Kos shall provide Jagotec with an interim report detailing an estimate of the royalty payments for each such fourth Calendar Quarter within **** days following the end of such Calendar Quarter.

7.3.1 Commencing with the First Commercial Sale of a Product, Kos shall keep, and shall require its relevant Affiliates to keep, complete and accurate records pertaining to the sale of Product for the later of (a) a period of **** after the year in which such sales occurred, and (b) **** after expiration of the shelf life for Product, and in sufficient detail to permit Jagotec to confirm the accuracy of the royalty payments paid by Kos pursuant to Section 6.3.

Said accountant shall not disclose to Jagotec or any other person any information, except that such accountant may disclose to Jagotec the fact of a deficiency, the lack of a deficiency or any overpayment, and the degree thereof, including the dollar amount. All results of any such examination shall be made available to Kos.

7.4.2 In the event that any audit reveals an overpayment or an underpayment in the amount of any payments that should have been paid by Kos to Jagotec, then the overpayment or underpayment amount, as the case may be, shall be paid within **** days after receipt of the final audit report, ****. ****. In addition, if the underpayment is in excess of **** of the amount that actually should have been paid, then Kos shall reimburse Jagotec for the reasonable cost of such audit.

7.5 Taxes.

7.5.1 Jagotec will be responsible for any income or other taxes owed by Jagotec or required by Applicable Laws to be withheld or deducted from any of the royalty and other payments made by or on behalf of Kos to Jagotec hereunder (“Withholding Taxes”), and Kos may deduct from any amounts that Kos is required to pay to Jagotec hereunder an amount equal to such Withholding Taxes as relate to such payments. Jagotec will provide Kos any information available to Jagotec that is necessary to determine the Withholding Taxes. Kos will pay such Withholding Taxes to the proper taxing authority for Jagotec’s account and will send evidence of such payment to Jagotec within one month of such payment. The Parties will do all such lawful acts and things and sign all such lawful deeds and documents as either Party may reasonably request from the other Party to enable Jagotec and Kos to take advantage of any applicable legal provision or any double taxation treaties with the object of paying the sums due to Jagotec hereunder without withholding or deducting any Withholding Taxes, or the recovery thereof.

7.5.2 Without limiting the immediately preceding sentence, Kos agrees that, with respect to any royalty or other payment made by or on behalf of Kos to Jagotec (as the beneficial owner) hereunder, after Kos has received both:

(b) such other documents as Kos determines constitute a sufficient basis upon which Kos may rely to establish that Kos does not know or have reason to know that it is, by reason of this Agreement, a financed entity in a conduit financing arrangement (as such terms are defined by Section 1.881-3 of the Treasury Regulations),

Kos will not, for the period during which such Form W-8BEN is in effect and during which Kos does not know or have reason to know that it is, by reason of this Agreement, a financed entity in a conduit financing arrangement, deduct or withhold any amount as Withholding Taxes for United States federal income tax purposes except to the extent that the United States is permitted, by the Treaty, to impose tax in such amount on income of the same type as such payment, derived by a resident of Switzerland that meets the requirements of the Treaty provision dealing with limitation on benefits with respect to such payment.

7.5.3 Should Jagotec be required by Applicable Laws to account for Swiss VAT, Kos shall also pay Jagotec such additional VAT. This shall apply only if Jagotec provides Kos with an invoice compliant with all the formal VAT requirements.

After the recovery of all such costs by both Parties, any award remaining thereafter shall be shared as follows:

(a) Except as otherwise provided in Section 8.3.5(b), any award remaining thereafter shall be divided between the Parties with **** to Kos and **** to Jagotec.

(b) Notwithstanding the foregoing and anything to the contrary contained herein, in the event that any portion of any award is specifically attributed by a court (or agreed upon in a settlement) to lost sales, such portion shall be shared by the Parties as if such amount constituted Net Sales in the Calendar Year in which such award is finally awarded by the court (or such settlement entered into), and any remaining portion of any such award shall be shared by the Parties equally.

8.4 Infringement Action by Third Parties. Unless otherwise covered by Jagotec’s indemnification obligation pursuant to Section 12.1.2, in the event of the institution or threatened institution of any suit by a Third Party against: (i) Kos, or its Affiliates, for Infringement involving the Jagotec Technology or Jagotec Marks, including the manufacture, use, offer to sell, sale, distribution or marketing of the Product in the Territory or importation of the Product into the Territory; and/or (ii) Jagotec or any other Person for Infringement involving the Jagotec Technology or Jagotec Marks in the Territory, Kos or Jagotec, as the case may be, shall promptly notify the other Party in writing of such suit or threatened suit.

The Parties shall equally share: (i) all costs and expenses

(including fees for attorneys and professionals) of such suit or threatened suit (including fees for attorneys and professionals) incurred by the Parties with respect to such action; and (ii) any damages awarded to and settlements made with any Third Party resulting from such suit or threatened suit. To the extent any award or damages are granted to Jagotec and/or its Affiliates, and/or Kos and/or its Affiliates, resulting from such suit or threatened suit (whether by way of judgment, award, decree, settlement or otherwise), the amount of the recovered award or damages shall first be used to reimbursing each Party for all costs and expenses (including fees for attorneys and professionals) incurred by each Party in defending against the suit or threatened suit on a pro-rata basis. Any remaining award or damages after reimbursement of Jagotec and Kos shall be split equally between the Parties. Each Party shall assist and cooperate with the other Party, at the other Party’s reasonable request and expense, in the defense of any such suit or threatened suit (including, without limitation, consenting to being named as a party thereto).

13.3.1 Either Party (the “Non-breaching Party”) may terminate this Agreement, without prejudice to any other remedies available to it at law or in equity, in the event the other Party (the “Breaching Party”) shall have breached any representation or warranty, or breached or defaulted in the performance of any of its material obligations hereunder and such breach or default shall have continued for **** after written notice thereof was provided to the Breaching Party by the Non-breaching Party (or, if such breach or default cannot be cured within such **** period, if the Breaching Party does not commence and diligently continue actions to cure such breach or default during such ****). Any such termination under this Section 13.3 shall become effective at the end of such **** notice period unless the Breaching Party has cured any such noticed breach(es) or default(s) prior to the expiration of such **** period (or, if such breach(es) or default(s) cannot be cured within such **** period, if the Breaching Party has commenced and diligently continues actions to cure such breach(es) or default(s)). The right of either Party to terminate this Agreement as provided in this Section 13.3 shall not be affected in any way by its waiver or failure to take action with respect to any previous breach or default.

13.3.2 If Kos is entitled to terminate this Agreement pursuant to Section 13.3.1 due to Jagotec’s breach of this Agreement, then Kos may, at its sole discretion, by written notice to Jagotec, either (a) terminate this Agreement in its entirety, or (b) terminate this Agreement in part as described in further detail in Section 13.9.

13.4 Termination Upon Withdrawal of the Product. This Agreement may be terminated at any time upon **** written notice by either Party, if the Product is permanently withdrawn from the market in the Territory.

13.5 Termination for Safety Concerns. If: (i) after the filing of a Registration Application for the Product, Kos determines, in its reasonable judgment after discussions with Jagotec, that the Product should be withdrawn due to a significant concern for the safety of the study subjects, which concern is based on a reasonable review of clinical data developed during the Development Program; or (ii) during the Product’s Commercialization Program, such Product becomes subject to a pattern of Serious Adverse Drug Experiences or either Party receives notice from a Regulatory Authority relating to a significant concern for safety, in each case which Kos, in good faith, reasonably believes would significantly impact the long-term viability of the Product; Kos shall have the right, upon **** prior written notice to Jagotec setting forth the reasons therefor in reasonable detail, to have the Steering Committee determine whether or not there exists such significant safety concerns or such significantly impact on the long-term viability of a Product and what, if anything, the Parties should do to address the matter; provided, however, that Kos shall have the right to immediately temporarily cease the marketing, sale and distribution of the Product until a final resolution is reached as provided in this Section 13.5. In the event the Steering Committee is unable to reach a unanimous resolution of the matter within **** of the matter being referred to the Steering Committee, Kos may terminate this Agreement upon **** prior written notice to Jagotec only if Kos, in good faith, reasonably believes that the patient safety issue would significantly eliminate the long-term viability of such Product and certifies the same to Jagotec in such written notice.

13.6 Termination upon Insolvency. Either Party may terminate this Agreement, if, at any time, the other Party shall file in any court or agency pursuant to any statute or regulation of any state or country, a petition in bankruptcy or insolvency or for reorganization or for an arrangement or for the appointment of a receiver or trustee of the Party or of substantially all of its assets, or if the other Party proposes a written agreement of composition or extension of substantially all of its debts, or if the other Party shall be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within **** after the filing thereof, or if the other Party shall propose or be a party to any dissolution or liquidation, or if the other Party shall make an assignment of substantially all of its assets for the benefit of creditors.

13.7 Other Termination Rights.

13.7.1 **** may terminate this Agreement in its entirety upon **** prior written notice **** is acquired (whether through merger, sale of stock representing fifty percent (50%) or more of the outstanding voting stock of ****, sale of all or substantially all of **** assets or otherwise) by, or the division or portion of the business of **** to which the Agreement relates is sold or otherwise transferred to, a company which promotes an **** product in the Territory and such acquirer does not (i) provide notice to **** within **** of its acquisition of **** (or the division or portion of the business of **** to which this Agreement relates), as applicable, of its intention to divest itself of such **** product; or (ii) having provided such notice to **** does not, actually divest itself of such **** product within **** of such acquisition. In any event, if such acquirer provides notice of its intention to divest itself of such **** product, such acquirer shall use Commercially Reasonable Efforts to consummate such divestiture within **** of such acquisition.

13.7.2 **** may terminate this Agreement in its entirety upon **** prior written notice to ****, if **** challenges any of the **** or **** that relate to the Product, including, without limitation, those Patents specified on Schedule 1.60 of this Agreement provided, that such termination right will expire **** after such interference or opposition becomes known to ****.

13.7.3

(a) If the first **** the Territory has not been obtained on or before ****, **** may terminate this Agreement upon **** prior written notice to ****.

(b) In the event that the Regulatory Authority requires any clinical or other trials in addition to the Core Clinical Program to be conducted in order to obtain Registration of the Existing Product for the Indications as provided in Section 4.2.2, and either Party reasonably believes that such requirements **** Product in the Territory to a date on or before ****, then such Party shall submit the concern to **** for a determination of whether such belief is accurate or not. If the **** determines (whether by consensus or through the use of an Expert as provided in Section 3.5.4) that such belief is accurate, such Party may terminate this Agreement upon **** prior written notice to the other Party. If the **** determines (whether by consensus or through the use of an Expert as provided in Section 3.5.4) that such belief is not accurate, then neither Party shall have the right to terminate this Agreement in such event.

13.7.4 **** may terminate this Agreement if the **** reasonably determines that the costs for the additional trials required by the Regulatory Authority as provided in Section 4.2.2 will exceed ****, and if the **** reasonably determines that the costs for the additional trials required by the Regulatory Authority as provided in Section 4.2.2 will exceed ****, **** may terminate this Agreement.

13.8.4 during the **** period following termination or expiration of this Agreement, Kos may sell its then-existing inventory of Products for the Field in the Territory and will pay all amounts due to Jagotec hereunder with respect to any Net Sales of such inventory occurring during such **** period.

13.10 Assignment of Supply Agreements with Third Parties.

13.11 Accrued Rights; Surviving Obligations. Termination, relinquishment or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of either Party prior to such termination, relinquishment or expiration.
