BMS shall have the reporting responsibility for such events to applicable regulatory health authorities anywhere in the world. Cephalon shall report all such adverse events involving the Product learned by it to: Vice President, Worldwide Safety & Surveillance Bristol-Myers Squibb Company P.O.

Instead, at the end of each such Agreement Year, a final reconciliation shall be conducted by comparing the amount to which Cephalon is otherwise entitled for such Agreement Year pursuant to Section 10(a) above (calculated using a single Net Sales per Script figure determined for the entire Agreement Year) against the sum of all amounts (if any) previously paid to Cephalon pursuant to this Section 10(c) for prior Agreement Payment Periods during such Agreement Year. If the calculation determines that Cephalon is due further compensation (or has been overcompensated by BMS) as a result of any trimester payments made by BMS with respect to the first two payment periods of any Agreement Year, the balance due to Cephalon (or to be refunded by Cephalon) shall be computed and paid by the applicable party to the other within sixty (60) days after the end of such Agreement Year. 17 (d) Compensation due Cephalon under this Section 10 above shall be calculated and paid within 60 days after the end of each Agreement Payment Period during the Copromotion Term, in accordance with Sections 10(a)-(c) and 11 hereof. 11.

If, as a result of any inspection of the books and records of BMS, it is shown that BMS' payments to Cephalon under this Agreement were less than 19 the amount which should have been paid, then BMS shall make all payments required to be made to eliminate any discrepancy revealed by said inspection within 30 days after Cephalon's demand therefor. If, as a result of any inspection of the books and records of Cephalon, it is shown that BMS's reimbursements for costs associated with Funded Activities to Cephalon under this Agreement were more than the amount which should have been paid, then Cephalon shall reimburse BMS for the discrepancy revealed by said inspection within 30 days after BMS's demand therefor. 12.

(a) BMS shall defend, indemnify and hold Cephalon and its employees, agents, officers, directors and affiliates (a "Cephalon Party") harmless from and against any and all losses, liabilities, obligations, claims, fees (including, without limitation, attorneys fees), expenses incurred by a Cephalon Party that result from or arise in connection with (i) the breach of any covenant, representation or warranty of BMS contained in this Agreement, (ii) the manufacturing, sale or distribution of the Product by BMS or any licensee or affiliate thereof, including, without limitation, any claim of patent infringement, (iii) any product liability claim related to the Product, including, without limitation, the use by any person of any Product that was manufactured, sold or distributed by BMS or any licensee or affiliate thereof, (iv) any contamination of or defect in the Product; and (v) breach by BMS of its obligations under Section 10 hereof. Notwithstanding anything in this Section 13(a), BMS shall not be obligated to indemnify a Cephalon Party for any liability related to the Product for which Cephalon has assumed an indemnification obligation under Section 13(b) below. 23 (b) Cephalon shall defend, indemnify and hold BMS and its employees, agents, officers, directors and affiliates (a "BMS Party") harmless from and against any and all losses, liabilities, obligations, claims, fees (including, without limitation, attorneys fees), expenses and lawsuits brought against or incurred by a BMS Party resulting from or arising in connection with (i) the breach by Cephalon of any covenant, representation or warranty of Cephalon contained in this Agreement and (ii) breach by Cephalon of its obligations under Section 10 hereof. (c) To receive the benefits of the indemnity under clauses (a) or (b) above, as applicable, an indemnified party must (i) give the indemnifying party written notice of any claim or potential claim promptly after the indemnified party receives notice of any such claim; (ii) allow the indemnifying party to assume the control of the defense and settlement (including all decisions relating to litigation, defense and appeal) of any such claim (so long as it has confirmed its indemnification obligation responsibility to such indemnified party under this Section 13); and (iii) so long as such cooperation does not vitiate any legal privilege to which it is entitled, reasonably cooperate with the indemnifying party in its defense of the claim (including, without limitation, making documents and records available for review and copying and making persons within its/his/her control available for pertinent testimony). If the indemnifying party defends the claim, an indemnified party may participate in, but not control, the defense of such claim at its/his/her sole cost and expense. An indemnifying party shall have no liability under this Section 13 as to any claim for which settlement or compromise of such claim or an offer of settlement or compromise of such claim is made by an indemnified party without the prior consent of the indemnifying party. (d) Cephalon acknowledges and agrees that any Cephalon sales force personnel (including contract sales personnel, telemarketers, independent contractors, employees, and agents) used by Cephalon to fulfill its obligations under this Agreement are not, and are not intended to be or be treated as, employees of BMS or any of its Affiliates, and that such individuals are not eligible to participate in any "employee benefit plans", as such term is defined in section 3(3) of ERISA, that are sponsored by BMS or any of its Affiliates. BMS shall not be responsible to Cephalon, to any employees, agents, contractors, telemarketers, or other personnel of Cephalon used by it to perform its obligations under this Agreement, or to any governmental entity for any compensation or benefits (including, without limitation, vacation and holiday remuneration, healthcare coverage or insurance, life 24 insurance, pension or profit-sharing benefits and disability benefits), payroll-related taxes or withholdings, or any governmental charges or benefits (including without limitation unemployment and disability insurance contributions or benefits and workmen' compensation contributions or benefits) that may imposed upon or be related to the performance by Cephalon and any of its employees, agents, contractors, telemarketers, or other personnel used by Cephalon to discharge its obligations under this Agreement, all of which shall be the sole responsibility of Cephalon, even if it is subsequently determined by any court, the IRS or any other governmental agency that such individual may be a common law employee of BMS or any of its Affiliates. All such matters of compensation, benefits and other terms of employment for any employee, agent, contractor, telemarketer, or other personnel used by Cephalon shall be solely a matter between Cephalon and such individual(s) or entities. Nothing contained in this Section 13(d) is intended to or will effect or limit any compensation payable by BMS to Cephalon for the services rendered by Cephalon pursuant to this Agreement. (e) Each party shall use commercially reasonable efforts to maintain adequate insurance against such risks (including product liability) and upon such terms (including coverages, deductible limits and self-insured retentions) as is customary for the activities to be conducted by it under this Agreement and is appropriate to cover its indemnification obligations hereunder. Each party shall furnish to the other evidence of such insurance, upon request. Such insurance information shall be kept in confidence in the same manner as any other confidential information disclosed by one party to the other hereunder. 14. Confidentiality. (a) Each party acknowledges that it may receive confidential or proprietary information of the other party in the performance of this Agreement. Each party shall hold confidential and shall not, directly or indirectly, disclose, publish or use for the benefit of any third party or itself, except in carrying out its duties hereunder, any confidential or proprietary information of the other party, without first having obtained the furnishing party's written consent to such disclosure or use. "Confidential or proprietary information" shall include, inter alia, know-how, scientific information, clinical data, efficacy and safety data, adverse event information, formulas, methods and processes, specifications, pricing information (including discounts, rebates and other price adjustments) and other terms and 25 conditions of sales, customer information, business plans, and all other intellectual property. This restriction shall not apply to any information within the following categories: (i) information that is known to the receiving party or its Affiliates prior to the time of disclosure to it, to the extent evidenced by written records or other competent proof; (ii) information that is independently developed by employees, agents, or independent contractors of the receiving party or its Affiliates without reference to or reliance upon the information furnished by the disclosing party, as evidenced by written records or other competent proof; (iii) information disclosed to the receiving party or its Affiliates by a third party that has a right to make such disclosure; (iv) information that is contained in any written promotional material prepared by BMS for use in connection with the Product; or (v) any other information that becomes part of the public domain through no fault or negligence of the receiving party. The receiving party shall also be entitled to disclose the other party's Confidential Information that is required to be disclosed in compliance with applicable laws or regulations (including, without limitation, to comply with SEC, NASDAQ or stock exchange disclosure requirements), or by order of any governmental body or a court of competent jurisdiction; provided that the party required to disclose such information shall use all reasonable efforts to obtain confidential treatment of such information by the agency or court. (b) This obligation shall survive the termination or expiration of this Agreement for five (5) years. (c) It is expressly understood and agreed that Cephalon may disclose confidential information to members of its board of directors who are not employees of Cephalon, provided, that Cephalon shall ensure that such directors are bound by a written obligation of 26 confidentiality to Cephalon as regards confidential information hereunder that is disclosed to them. 15.
