The United States dollar equivalent shall be calculated using the average of the exchange rates (local currency per US$1) published in The Wall Street Journal, Western Edition, under the heading “Currency Trading” on the last business day of each month in the applicable calendar quarter. All royalties payable hereunder shall be calculated based on Net Sales expressed in United States dollars.

4.6.3 ViroPharma shall keep, to the extent such information is reasonably available, complete and accurate records in sufficient detail to properly reflect all gross sales and Net Sales and to enable the royalties payable to be determined.

Neither party shall disclose any terms or conditions of this Agreement to any third party without the prior consent of the other party; provided, however, that a party may disclose the terms or conditions of this Agreement (a) on a need-to-know basis to its legal and financial advisors to the extent such disclosure is reasonably necessary or (b) to a third party in connection with (i) an equity investment in such party, (ii) a merger, consolidation or similar transaction by such party, (iii) the sale of all or substantially all of the assets of such party or (iv) a collaboration or strategic alliance relating to the subject mater of this Agreement.

9.3 Permitted Disclosures. The confidentiality obligations under this Article 9 shall not apply to the extent that a party is required to disclose information by applicable law, regulation, stock exchange listing or order of a governmental agency or a court of competent jurisdiction; provided, however, that such party shall provide written notice thereof to the other party, consult with the other party with respect to such disclosure and provide the other party sufficient opportunity to object to any such disclosure or to request confidential treatment thereof.

9.4.1 Prior to the Regulatory Approval Date, either party may publish the results of its research and/or development under this Agreement in order to obtain recognition within the scientific community and to advance the state of scientific knowledge, and such publication shall be subject to the following procedures.

If the other party requests such a delay, the publishing party shall delay submission or presentation of the publication and shall not proceed with the written publication or the presentation without the prior written consent of the other party, such consent not to be unreasonably withheld (provided that it would be unreasonable (x) for ViroPharma to withhold consent if ViroPharma’s primary reason for doing do is marketing concerns due to the Product performing better than a ViroPharma Subcutaneous Product or (y) for Halozyme to withhold consent if Halozyme’s primary reason for doing so is marketing concerns due to the Product performing worse than a ViroPharma Subcutaneous Product).

9.4.2 After the Regulatory Approval Date, ViroPharma may publish the results of its research and/or development under this Agreement in order to obtain recognition within the scientific community and to advance the state of scientific knowledge, and such publication shall be subject to the following procedures. If ViroPharma desires to make any such publication (including any oral disclosure made without obligation of confidentiality), ViroPharma shall provide Halozyme with a copy of the proposed written publication at least *** (***) days prior to submission for publication, or an outline of such oral disclosure at least *** (***) days prior to presentation. At the reasonable request of Halozyme, ViroPharma shall remove any Confidential Information of Halozyme therefrom.

Halozyme additionally shall have the right (a) to propose modifications to the publication for patent reasons, and (b) to request a reasonable delay in publication in order to protect patentable information. If Halozyme requests such a delay, ViroPharma shall delay submission or presentation of the publication for a period of up to *** (***) days to enable Halozyme to prepare and file applicable patent applications. Upon the expiration of such *** (***) day period (in the case of proposed written disclosures) or *** (***) day period (in the case of proposed oral disclosures) from receipt by Halozyme, subject to the requirement to remove any Confidential Information of Halozyme, ViroPharma shall be free to proceed with the written publication or the presentation, respectively, unless Halozyme has requested the delay described above.

10. INDEMNIFICATION AND INSURANCE.

10.1 By ViroPharma. ViroPharma shall indemnify and hold harmless Halozyme, and its directors, officers, employees and agents, from and against all losses, liabilities, damages and expenses, including reasonable attorneys’ fees and costs (collectively, “Liabilities”), resulting from any claims, demands, actions or other proceedings by any third party to the extent resulting from (a) the breach of any representation, warranty or covenant by ViroPharma under this Agreement; (b) the use by ViroPharma, its sublicensees or their respective Affiliates of the Licensed IP Rights beyond the scope of the licenses granted herein; (c) the manufacture, use, sale, handling or storage of Products by ViroPharma, its sublicensees or their respective Affiliates, customers or end-users; or (d) the use by ViroPharma, its sublicensees or their respective Affiliates of the Confidential Information of Halozyme.

10.2 By Halozyme. Halozyme shall indemnify and hold harmless ViroPharma, and its directors, officers, employees and agents, from and against all Liabilities resulting from any claims, demands, actions or other proceedings by any third party to the extent resulting from (a) the breach of any representation, warranty or covenant by Halozyme under this Agreement; (b) the use by Halozyme, its sublicensees or their respective Affiliates of the Grantback Patents beyond the scope of the licenses granted herein; (c) the manufacture, use, sale, handling or storage of API by Halozyme or its CMOs or other suppliers; or (d) the use by Halozyme, its sublicensees or their respective Affiliates of the Confidential Information of ViroPharma.

10.3 Procedure. If a party (the “Indemnitee”) intends to claim indemnification under this Section 10.3, it shall promptly notify the other party (the “Indemnitor”) in writing of any claim, demand, action or other proceeding for which the Indemnitee intends 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 an 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 the Indemnitee and any other party represented by such counsel in such proceeding. The obligations of this Section 10.3 shall not apply to amounts paid in settlement of any claim, demand, action or other proceeding if such settlement is effected without the consent of the Indemnitor, which consent shall not be withheld or delayed 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 the Indemnitor of any obligation to the Indemnitee under this Section 10.3. The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any claim, demand, action or other proceeding covered by this Section 10.3.

Each party retains the right to insure or self-insure at its sole discretion, the above coverage. Each party shall provide the other party *** (***) days notice of any material change, cancellation or non-renewal of any required insurance under this Agreement.
