than • (€ • ) euros, and the remainder of the minimum royalty payments for such year are creditable against the milestones of Section 10.2 above. Such credits are to carry forward, year to year, until exhausted.

11.3: Running Royalties. AvP agrees to pay to CRUCELL royalties (exclusive of any applicable V.A.T.) on the total NET SALES of FLU VACCINE PRODUCTS sold in AvP TERRITORY as calculated below in Sections 11.3.1 through 11.8.
11.3.1: AvP's obligation to pay a royalty is, on a product-by-product and country-by-country basis, for the longer of a period of (i) fifteen (15) years following the FIRST COMMERCIAL SALE of FLU VACCINE PRODUCT, or (ii) the last to expire PROJECT PATENT jointly or solely owned by CRUCELL with a VALID CLAIM in that country such that the VALID CLAIM would, but for the license granted herein, be infringed by the manufacture, use, sale or importation of FLU VACCINE PRODUCT (hereinafter the "ROYALTY TERM"), at the rate(s) set forth below in this subsection.
11.3.2: The Parties agree to use as a basis for calculating the royalties due to CRUCELL, the hypothetical annual net sales amount on a country-by-country basis ("Annual Base Net Sales" or "W_n", whereby n represents the year) that AvP is forecasted to make with its conventional influenza products after start of commercialization of FLU VACCINE PRODUCT, in accordance with the following calculation:
11.3.2.1: W_n = X (1 + Z)ⁿ for each of the first • years following start of commercialization of the first FLU VACCINE PRODUCT (where n = • to • for the year • to • ). W_n = X (1 + Z)⁶ after the first • years following start of commercialization of the first FLU VACCINE PRODUCT.
11.3.2.2: The Initial Base Net Sales ("X") is the total NET SALES made by AvP with its conventional influenza vaccines in the AvP TERRITORY during the last year prior to commercialization of the first FLU VACCINE PRODUCT.
11.3.2.3: The trend rate in NET SALES ("Z") is the percentage increase or decrease of NET SALES made by AvP with its conventional influenza vaccines in the AvP TERRITORY during the two years prior to the first year of commercialization of the first FLU VACCINE PRODUCT, provided that Z shall not be greater than • % or less than • %.
11.3.3: During the ROYALTY TERM, the royalties shall be calculated as follows:

The total NET SALES of the FLU VACCINE PRODUCT for each year is hereafter referred to as "Y_n".

The royalty rate applicable during each year shall be determined as follows:

If Y_n is less than or equal to W_n, then the royalty rate is • percent ( • %) of total NET SALES; that is • % of Y_n.

If Y_n is greater than W_n, then the royalty rate is • percent ( • %) of total NET SALES of W_n plus • percent ( • %) of the incremental NET SALES; that is • % of W_n plus • % of (Y_n-W_n).

11.4: Royalty for Life of Unexpired PROJECT PATENT Term. If the use, manufacture or sale of FLU VACCINE PRODUCT in a country would infringe, absent this Agreement, a VALID CLAIM of a PROJECT PATENT in such country, the earned royalty obligation for sales in such country will be 100% of the royalty obligation on NET SALES as defined hereinabove in Section 11.3.
11.5: Royalty Reduction on PROJECT PATENT Expiration. If PROGRAM KNOW HOW or CRUCELL KNOW HOW is used in the use, manufacture or sale of FLU VACCINE PRODUCT in any

country, and if the use, manufacture or sale of FLU VACCINE PRODUCT would not infringe, absent this Agreement, a VALID CLAIM of a PROJECT PATENT in any country, the earned royalty obligation will be • % of the royalty obligation on NET SALES as defined hereinabove in Section 11.3)(i.e. • % of Y if Y is less or equal to X, or • % of X + • % of (Y-X) if Y is greater than X).

11.6: One royalty shall be due with respect to the sale of the same unit of FLU VACCINE PRODUCT.
11.7: AvP Obligations. AvP shall be solely responsible for the payment of any royalties, license fees, and milestone or other payments due to third parties under licenses or similar agreements necessary to allow the manufacture, use or sale of any FLU VACCINE PRODUCT in the AvP TERRITORY and CRUCELL TERRITORY.
11.8: IF AvP develops and launches an alternative delivery system for flu vaccines, the royalty payable by AvP to CRUCELL per unit sold of such alternative delivery system would be based on a country-by-country basis on the greater of (i) the value contributed by the different components of the combination product, or (ii) if a standard injectable FLU VACCINE PRODUCT is sold in such country, the price of one unit of the standard injectable FLU VACCINE PRODUCT.

12 PAYMENTS; BOOKS AND RECORDS

12.1: Royalty Reports and Payments. After the first commercial sale of a FLU VACCINE PRODUCT on which royalties are required, AvP agrees to submit quarterly written reports to CRUCELL within ninety (90) days after the end of each calendar quarter, stating in each such report the number, description, and aggregate NET SALES of the FLU VACCINE PRODUCT sold during the calendar quarter upon which a royalty is payable under Section 11 above. Concurrently with the submission of such reports, AvP shall pay to CRUCELL royalties at the rate specified in Section 11.
12.2: Method of Payment.
12.3: All payments due hereunder to CRUCELL shall be paid in Euros in immediately available funds, for CRUCELL's account, to a bank designated in writing by CRUCELL.
12.4: Each Party shall submit an invoice to the other Party for all transportation, packing or other documented and reasonable costs incurred by such Party on the other Party's benefit and at the other Party's request pursuant to this Agreement. Each Party shall pay undisputed invoices specifying these costs within thirty (30) days of receipt.
12.5: Interest. If any payment under this Agreement is not made by the date on which the same becomes due and payable, the late Party shall owe the other Party interest at the rate of LIBOR + 2 percent (%) per annum on any outstanding amount until payment is made in full.
12.6: No Refunds. Payments referred to herein shall not be refundable under any circumstances, including but not limited to the termination of this Agreement for whatever reason.
12.7: Currency Conversion. If any currency conversion shall be required in connection with the calculation of royalties hereunder, such conversion shall be made using the following procedures. The rate of currency conversion shall be calculated using a simple monthly period average of the end "spot rates" provided by a leading commercial bank for such accounting period. Any changes to procedures for currency conversion shall only apply after such notice has been delivered and provided that such changes are consistently applied across AvP's operating units and continue to maintain a set methodology for currency conversion.
12.8: Withholding Taxes. AvP shall pay royalty payments to CRUCELL after deduction of any applicable withholding taxes. Prior to any first payment by AvP to CRUCELL in one calendar year,

CRUCELL shall provide AvP with any relevant form required by the Tax authorities in order for CRUCELL to (i) attest CRUCELL's fiscal residence and (ii) obtain the application of the reduced withholding tax rate or the exemption of the withholding tax, according to the relevant bilateral agreement against double taxation. At the request of CRUCELL, AvP will forward to CRUCELL such relevant application forms for fulfillment. In the event CRUCELL fails to return such forms duly filled and signed before a payment date, AvP will declare and pay withholding tax at the local common law rate applicable to the payments, and AvP will deduct such tax from the corresponding payment to CRUCELL. AvP shall remit the withholding tax to the proper Tax authority and proof of payment of such tax shall be secured and sent to CRUCELL as evidence of such payment.

12.9: Records; Inspection. Each Party and its AFFILIATES shall keep complete, true, and accurate books of account and records for the purpose of determining the royalty amounts payable under this Agreement. Such books and records shall be kept at the principal place of business of such Party or its AFFILIATE, as the case may be, for at least three (3) years following the end of the calendar quarter to which they pertain. Such records will be open for inspection during such three (3) year period by an independent public accounting firm of national prominence retained by the other Party for the purpose of verifying the royalty statements. Such inspections may be made no more than once each calendar year, at reasonable times mutually agreed by AvP and CRUCELL. The auditing Party's representative or agent will be obliged to execute a reasonable confidentiality agreement prior to commencing any such inspection. Inspections conducted under this Section shall be at the expense of the auditing Party, unless a variation or error producing an increase exceeding ten percent (10%) of the amount stated for any period covered by the inspection is established in the course of any such inspection, whereupon all costs relating to the inspection for such period will be paid the Party being audited.

13 INTELLECTUAL PROPERTY

13.1: Ownership of Inventions. Inventorship of inventions and other intellectual property rights conceived and/or reduced to practice in connection with the DEVELOPMENT PROGRAM shall be determined in accordance with the patent and other intellectual property laws of the country in which the invention was made. The Parties shall jointly own title to all inventions made by at least one AvP employee and at least one CRUCELL employee during the course of, and as part of, the DEVELOPMENT PROGRAM. Except as expressly provided in this Agreement, it is understood that the Parties shall not have an obligation to account to the other for profits, or to obtain any approval of the other Party to license or exploit a joint invention, by reason of joint ownership of any such intellectual property. Each Party shall cooperate in executing whatever documents are necessary to establish legal joint title in and common ownership of PROGRAM PATENTS claiming jointly owned inventions.
13.2: Patent Prosecution.
13.2.1: Sole Inventions. AvP or CRUCELL, as the case may be, shall, at its own expense, control the preparing, filing, prosecuting and maintaining the solely owned CRUCELL PATENTS and PROGRAM PATENTS worldwide, in such countries as it deems appropriate, and conducting any interferences, re-examinations, reissues, oppositions or requests for patent term extensions relating to solely owned PROGRAM PATENTS and CRUCELL PATENTS (respectively) using counsel of that Party's choice.
13.2.2: Jointly Owned PROGRAM PATENTS. To provide for the most sensible, efficient, and cost effective means to protect inventions that are owned jointly by CRUCELL and AvP under Section 13.1 above, patent counsel for AvP and CRUCELL shall consult with each other. As a result of such consultation, patent counsel will be chosen to prepare, file, prosecute and maintain

patent applications and patents worldwide on such joint inventions, and the Parties shall share the costs thereof as reasonably agreed, based upon the relative benefits thereof to each Party.

13.2.3: Prosecution by Other Party. In the event that AvP or CRUCELL, as the case may be (the "Owner"), declines to file or, having filed, declines to further prosecute and maintain any CRUCELL PATENT or PROGRAM PATENT, or conduct any interferences or oppositions, or request any re-examinations, reissues or extensions of patent term with respect to its solely owned PROGRAM PATENTS or CRUCELL PATENTS, the other Party shall have the right to file, prosecute and maintain such patent applications or patents or conduct such interferences, at its own expense, in the name of the Owner in any country, in which event the Owner of such CRUCELL PATENT or PROGRAM PATENT shall provide, at the other Party's request and expense, all reasonable assistance. If the Owner of such CRUCELL PATENT or PROGRAM PATENT declines or fails to take any such actions, such Owner shall notify the other Party hereto at least sixty (60) days prior to the date the next action or filing is due to be taken with respect to the subject CRUCELL PATENT or PROGRAM PATENT.
13.2.4: Cooperation. Each of AvP and CRUCELL shall keep the other reasonably informed as to the status of such patent matters relating to jointly owned PROGRAM PATENTS, including, without limitation, by providing the other the opportunity to review and comment on any documents which will be filed in any patent office, and providing the other copies of any documents that such Party receives from such patent offices, including notice of all interferences, re-examinations, oppositions or requests for patent term extensions. AvP and CRUCELL shall each cooperate with and assist the other in connection with such activities, at the others' request and expense.
13.2.5: Third Party Rights. The foregoing provisions of this Section 13 shall be subject to and limited by any agreements pursuant to which AvP and CRUCELL, as the case may be, acquired any particular PROGRAM PATENT or CRUCELL PATENT. It is understood that such agreements may require, for example, that the licensor Party from whom AvP or CRUCELL acquired a license to such PATENT control the prosecution of particular patents and patent applications and does not permit access or an opportunity to comment on any documents filed in patent offices.
13.3: Defense of Third Party Infringement Claims.
13.3.1: Infringement Claims. If the production, sale or use of any VACCINE PRODUCT developed pursuant to this Agreement results in a claim, suit or proceeding alleging patent infringement against AvP or CRUCELL (or their respective AFFILIATES or SUBLICENSEES), such Party shall promptly notify the other Party hereto in writing setting forth the facts of such claim in reasonable detail. The Party subject to such claim shall have the exclusive right to defend and control the defense of any such claim, suit or proceeding, at its own expense, using counsel of its own choice, provided, however, it shall not enter into any settlement which admits or concedes that any aspect of the PATENT or KNOW HOW of the other Party hereto is invalid or unenforceable without the prior written consent of such other Party. Such Party shall keep the other Party hereto reasonably informed of all material developments in connection with any such claim, suit or proceeding.
13.4: Enforcement.
13.4.1: Notification. In the event that a Party obtains actual knowledge that a third party is infringing one or more of the PROGRAM PATENTS or the CRUCELL PATENTS in the field of VACCINE PRODUCTS, it shall promptly notify the other Party of any such infringement.
13.4.2: Control of Suit:
13.4.2.1: As to the infringement of solely owned CRUCELL PATENTS, CRUCELL shall have the exclusive right and sole discretion to effect termination of such infringement, including bringing

suit or other proceedings against the infringer in its own name and AvP shall be kept informed at all times of all such proceedings taken by CRUCELL but only so as far as the CRUCELL PATENT in suit relates to a FLU VACCINE PRODUCT. If CRUCELL requests, AvP may, at AvP's discretion, join with CRUCELL as a Party to the lawsuit or other proceeding at CRUCELL' expense; however, CRUCELL shall retain control of the prosecution of such suit or proceedings, as the case may be.

13.4.2.2: As to the infringement of PROGRAM PATENTS solely owned by AvP, AvP shall have the exclusive right and sole discretion to effect termination of such infringement, including bringing suit or other proceedings against the infringer in its own name and CRUCELL shall be kept informed at all times of all such proceedings taken by AvP only so as far as the PROGRAM PATENT in suit relates to a VACCINE PRODUCT. If AvP requests, CRUCELL may, at CRUCELL's discretion, join with AvP as a Party to the lawsuit or other proceeding at AvP's expense; however, AvP shall retain control of the prosecution of such suit or proceedings, as the case may be.
13.4.2.3: Jointly Owned Technology. In the event that any PROGRAM PATENT that is jointly owned by CRUCELL and AvP is infringed or misappropriated by a third party, AvP and CRUCELL shall negotiate in good faith to mutually agree upon whether, and, if so, how, to enforce such jointly owned PROGRAM PATENT or defend such jointly owned PROGRAM PATENT in a declaratory judgment or similar proceeding. If the Parties cannot agree, then as joint and several owners of the PROGRAM PATENT, each Party may exercise its legal rights without the consent of the other Party.
13.4.3: Costs and Monetary Recovery: Each Party shall bear all its costs incurred in connection with such lawsuit or other proceeding, and consequently shall be entitled to collect and retain for its own account any damages or profits as may be accrued as a result of such lawsuit or other proceeding.

16 INDEMNIFICATION

16.1: CRUCELL shall not be liable for and AVP shall indemnify and hold CRUCELL, its officers, directors, employees and agents ("CRUCELL Indemnitee") harmless against any and all liabilities (including product liability), except for the willful misconduct or negligence of CRUCELL, damages, losses or injury, death, costs, and expenses, whether direct or indirect, consequential or incidental, including attorney's fees, arising in any manner from AvP's use of PER.C6 CELLS, PER.C8 CELLS and/or the CRUCELL KNOW HOW, PROGRAM TECHNOLOGY and/or VACCINE PRODUCTS including without limitation any liability arising from the inherent properties of any PER.C8 CELL or PER.C6 CELL, or the development or manufacture of prototypes or clinical supplies by AVP, or the use by AVP of CRUCELL KNOW HOW or the use of any VACCINE PRODUCT manufactured, or used by AVP by any human being regardless of whether such use was contemplated by the Parties.
16.2: AvP shall not be liable for and CRUCELL shall indemnify and hold AvP, its officers, directors, employees and agents ("AvP Indemnitee") harmless against any and all liabilities (including product liability), except for the willful misconduct or negligence of AvP, damages, losses or injury, death, costs, and expenses, whether direct or indirect, consequential, incidental, including attorney's fees, arising in any manner from CRUCELL's use of PROGRAM KNOW HOW and/or VACCINE PRODUCT provided by AvP, including without limitation any liability arising from the inherent properties of any AvP PROGRAM KNOW HOW and/or VACCINE PRODUCT, or the development or manufacture of prototypes or clinical supplies by CRUCELL, or the use by CRUCELL of AvP PROGRAM KNOW HOW or the use of any VACCINE PRODUCT manufactured, or used by CRUCELL by any human being regardless of whether such use was contemplated by the Parties.
16.3: Procedure. A Party (the "Indemnitee") that intends to claim indemnification under this Section shall promptly notify the other Party (the "Indemnitor") in writing of any loss, claim, damage, liability or action in respect of which the Indemnitee or any of its Affiliates, SUBLICENSEES or their directors, officers, employees or agents intend to claim such indemnification, and the Indemnitor shall have the right to participate in, and, to the extent the Indemnitor so desires, to assume the defense thereof with counsel mutually satisfactory to the Parties; provided, however, that Indemnitee shall have the right to retain its own counsel, with the fees and expenses to be paid by the Indemnitor, if representation of such Indemnitee by the counsel retained by the Indemnitor would be inappropriate due to actual or potential differing interests between such Indemnitee and any other Party represented by such counsel in such proceeding. The indemnity agreement in this Section shall not apply to amounts paid in settlement of any loss, claim, damage, liability, or action if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld unreasonably. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such Indemnitor of any liability to the Indemnitee under this Section but the omission so to deliver written notice to the Indemnitor shall not relieve it of any liability that it may have to any Indemnitee otherwise than under this Section. The Indemnitee under this Section, its employees and agents, shall cooperate fully with the Indemnitor and its legal representatives in the investigation of any action, claim or liability covered by this indemnification.
