As further consideration for the licenses and other rights granted to ALTEON under this Agreement, ALTEON shall pay WASHINGTON the following milestone payments within six (6) months following the first occurrence of each event set forth below with respect to each Initial Product in each Dosage Form: (a) [C.I.] upon commencement of Phase I/II clinical trials in the United States; (b) [C.I.] upon commencement of Phase III clinical trials in the United States; and (c) [C.I.] upon filing an NDA in the United States; and (d) [C.I.] upon receipt of NDA approval from the FDA, including any required marketing and pricing approval. -9- 15 Exhibit 10.10 With respect to the first Initial Product in the first Dosage Form, such payments shall be made in any event no later than (i) June 30, 1997 with respect to the payment due under Section 5.3(a), (ii) December 31, 1997 with respect to the payment due under Section 5.3(b), and (iii) December 31, 1998 with respect to the payment due under Section 5.3(c). 5.4 Credit Against Royalties. With respect to any milestone payments made pursuant to Section 5.3, for each Initial Product in each Dosage Form ALTEON shall be entitled to a credit against running royalties due under Section 5.6 of this Agreement for such Product in the Territory in each of the first ten calendar semi-annual periods following the First Commercial Sale of such Product in an amount equal to the lesser of: (i) [C.I.] of the aggregate amount of such milestone payments, or (ii) the amount of the royalties due for such Product for such period in excess of the minimum royalties due for such period. Such credit, if any, shall be applied when the royalties for such semi-annual period are due pursuant to Section 6.1. Such credit may only be taken against royalties otherwise due for Products of the same Dosage Form as that for which the milestone payments were made. Any credit not taken or eligible to be taken in the applicable semi-annual period shall expire and shall not be carried into any other periods. 5.5 Pre-Commercialization Income from Sublicensees. (a) In the event that ALTEON and/or its Affiliates receive Pre-Commercialization Income from any sublicensee, ALTEON shall pay to WASHINGTON: (i) a first amount equal to [C.I.] of the aggregate Pre-Commercialization Income received by ALTEON and/or its Affiliates which such sublicensee may credit against its running royalties, plus (ii) a second amount equal to [C.I.] of the aggregate of all other Pre-Commercialization Income received by ALTEON and/or its Affiliates, but such second amount shall then be reduced by the amount of all payments made by ALTEON to WASHINGTON pursuant to Sections 5.1, 5.2 and 5.3 through the last day of the calendar semi-annual period in which such payment of such second amount of other Pre-Commercialization Income was received (less any such payments previously applied against previously received Pre-Commercialization Income). To the extent that any Pre-Commercialization Income can be identified to relate specifically to one or more Dosage Forms, the amount by which [C.I.] of the aggregate Pre-Commercialization Income is reduced shall be limited only to the milestone payments made with respect to such Dosage Form(s). Such payments shall be made within thirty (30) days after the end of the calendar semi-annual period in which it was received. In the event that any payments made by ALTEON pursuant to this Section 5.5 are made before all payments due under Sections 5.1, 5.2 and 5.3 have been accrued, such payment(s) under this Section 5.5 shall be deemed to be a prepayment of any payments subsequently due under Sections 5.1, 5.2 and 5.3. (b) By way of illustration of the application of Section 5.5(a), if ALTEON has paid a total of [C.I.] to WASHINGTON pursuant to Sections 5.1, 5.2 and 5.3 at the time that it grants a sublicense to Company X, and the sublicense provides for an up-front payment of [C.I.] which is not creditable against running royalties, then ALTEON will pay WASHINGTON [([C.I.] of [C.I.]) - [C.I.]], or [C.I.]. Such payment will be deemed to be a prepayment of subsequent payments due under 5.1, 5.2 or 5.3. Thereafter, as payments become due under Sections 5.1, 5.2 or 5.3, the [C.I.] payment will be applied against such payments then due under 5.1, 5.2 or 5.3 until it is fully used. So, if a milestone payment of [C.I.] becomes due in the following period, ALTEON shall make no additional payment, but the amount of such prepayment shall be reduced by the amount of such milestone payment, such that a prepayment of [C.I.] - [C.I.], or [C.I.], remains. -10- 16 Exhibit 10.10 In addition, if ALTEON subsequently receives an additional up-front or milestone payment of [C.I.] from Company X, and in the interim ALTEON has paid to WASHINGTON an additional [C.I.] in payments pursuant to Section 5.1, 5.2 or 5.3, ALTEON will pay WASHINGTON [([C.I.] of [C.I.]) - [C.I.]], or [C.I.], from which ALTEON may deduct the remaining [C.I.] prepayment. 5.6 Running Royalties. As further consideration of the license and other rights granted to ALTEON under this Agreement, ALTEON shall pay to WASHINGTON a royalty, commencing on the First Commercial Sale of a Product by ALTEON, its Affiliates or its sublicensees, as follows: (a) For Commercial Sales made by ALTEON and its Affiliates, ALTEON shall pay to WASHINGTON a royalty equal to [C.I.] of the annual Net Sales for the first [C.I.] in Net Sales for each calendar year, and [C.I.] of the annual Net Sales for any Net Sales over [C.I.] for such calendar year. (b) For Commercial Sales made by any sublicensee of ALTEON or its Affiliates, ALTEON shall pay to WASHINGTON a royalty equal to [C.I.] of ALTEON's Post-Commercialization Income for such period. (c) For any Product relating solely to Joint Inventions, and which does not utilize any Licensed Technology other than Joint Inventions, or which is not covered by a Licensed Patent other than jointly owned Licensed Patents, the royalty rates set forth in Sections 5.6(a) and 5.6(b) shall be reduced by [C.I.] with respect to such Product in the Territory. (d) The Parties intend and expect that they will be able to secure patents covering the Products. However, during any period when (i) the use or sale of a Product would not infringe a Valid Claim of any Licensed Patent in the country in the Territory where it is used or sold such that a third party would be permitted to sell competing products, and (ii) either (A) no patent application has been filed which, if issued, would cover such Product in such country, then the royalty rates set forth in Sections 5.6(a) and 5.6(b) shall be reduced by [C.I.] with respect to such Product in such country during such period, or (B) a patent application has been filed which, if issued, would cover such Product in such country, then the royalty rates set forth in Sections 5.6(a) and 5.6(b) shall be reduced by [C.I.] with respect to such Product in such country during the pendency of such patent application. In the event that a patent application has been filed and is pending for a period of time such that, the Parties agree, in good faith, that it is reasonable to believe that no patent will be issued from such patent application, then thereafter, the royalty rates shall be reduced as provided in clause (A) of this Section. (e) During any period when either: (i) the Compound, or (ii) any other compound licensed by WASHINGTON, is available for use or sale in any country in the Territory by a third party (other than an Affiliate or sublicensee of ALTEON) for use in the Field in such a manner that such use or sale would not infringe a Valid Claim of any Licensed Patent in such country and ALTEON experiences effective competition which has a substantial negative impact on sales of Products by ALTEON or any of its Affiliates or sublicensees, the royalty rates set forth in Sections 5.6(a) and 5.6(b) shall be reduced by [C.I.] with respect to such Product in such country. ALTEON shall provide to WASHINGTON a written notice of any event covered by this Section 5.6(e), which shall include an explanation of the facts and information which give rise to such event. (f) Notwithstanding the foregoing, ALTEON shall only be entitled to a [C.I.] reduction of the royalty rate once with respect to any Product in any country in the Territory pursuant to any provision in this Agreement. -11- 17 Exhibit 10.10 5.7 Annual Minimum Royalties. During each full calendar year after the First Commercial Sale of the Initial Product in the United States during the term of this Agreement, ALTEON shall pay to WASHINGTON minimum royalties as follows: (a) For the first full calendar year after the First Commercial Sale in the United States, the minimum royalty shall be [C.I.]; (b) For the second full calendar year after the First Commercial Sale in the United States, the minimum royalty shall be [C.I.]; and (c) For the each full calendar year thereafter, and until this Agreement terminates with respect to all Products in the United States, the minimum royalty shall be [C.I.]. One-half of the applicable annual minimum royalty shall be paid within thirty (30) days after the end of the first semi-annual period in such calendar year, and the balance shall be paid within thirty (30) days after the end of the second semi-annual period in such calendar year. ALTEON shall be entitled to a full credit of the annual minimum royalty against running royalties due for the applicable calendar year pursuant to Section 5.6. 5.8 Obligation to Pay Royalties. (a) The Parties acknowledge and agree that ALTEON owns or controls separate intellectual property rights relating to the use of the Compound using different mechanisms of action and making different claims in its patents and patent applications relating to the Compound. The Parties agree that ALTEON shall only be obligated to pay royalties to WASHINGTON on the sales of products making use of the Compound if the allowed claims for the sale and promotion of such products by the United States Food and Drug Administration or the successor thereto, or its equivalent in any other country, is consistent with the claims contained in the Licensed Patents with respect to the Compound, and such sales and promotion are based upon such claims. ALTEON shall use all reasonable commercial efforts to develop formulations of Products which differ from any formulations of other products making use of the Compound which may be marketed pursuant to claims of other patents so that there may be avoidance of doubt as to which products shall be governed by the Licensed Patents under this Agreement. (b) The obligation to pay royalties to WASHINGTON under this ARTICLE 5 is imposed only once with respect to the same unit of Product regardless of the number of Licensed Patents or Licensed Technology pertaining thereto. There shall be no obligation to pay royalties to WASHINGTON under this ARTICLE 5 on sales of Products between ALTEON, its Affiliates and its sublicensees, but in such instances the obligation to pay royalties shall arise upon the sale by ALTEON, its Affiliates or its sublicensees to unrelated third parties. Payments of running royalties due under this ARTICLE 5 based on Net Sales shall be deemed to accrue when Products are shipped or billed, whichever event shall first occur. Payments of running royalties due under this ARTICLE 5 based on Post-Commercialization Income shall be deemed to accrue when ALTEON receives such Post-Commercialization Income. -12- 18 ARTICLE 6 - PAYMENTS AND REPORTS 6.1 Payment. All running royalty payments due pursuant to Section 5.6(a) shall be paid semi-annually within sixty (60) days after the end of each June 30 and December 31 of each calendar year. All running royalty payments due pursuant to Section 5.6(b) shall be paid semi-annually within thirty (30) days after the end of each June 30 and December 31 of each calendar year. Each such payment shall be accompanied by a statement for each Dosage Form of the amount of Net Sales and Post-Commercialization Income during such semi-annual period, the amount of royalties due on such Net Sales and Post-Commercialization Income and the amount of any credits being applied to such royalties. 6.2 Mode of Payment. ALTEON shall make all payments required under this Agreement in the United States in United States Dollars. The royalty payments due shall be translated at the rate of exchange at which United States Dollars are listed in The Wall Street Journal for the currency of the country in which the royalty is accrued for the last business day of the calendar semi-annual period in which such sales were made. 6.3 Late Payments. ALTEON shall pay interest to WASHINGTON on the aggregate amount of any payments that are not paid on or before the date such payments are due under this Agreement at a rate per annum equal to the lesser of: (i) the prime rate of interest as published in the United States in The Wall Street Journal under the caption "Money Rates" on the date such payment was due, plus three percent (3%), or (ii) the highest rate permitted by applicable law; calculated on the actual number of days such payment is late. 6.4 Records Retention. ALTEON and its Affiliates shall keep complete and accurate records pertaining to the sale of Products in the Territory and covering all transactions from which Net Sales, Pre-Commercialization Income or Post-Commercialization Income are derived for a period of three calendar years after the year in which such sales occurred, and in sufficient detail to permit WASHINGTON to confirm the accuracy of royalty calculations hereunder. 6.5 Audit Request. At the request and expense of WASHINGTON, ALTEON and its Affiliates shall permit an independent, certified public accountant appointed by WASHINGTON and acceptable to ALTEON or its Affiliate, at reasonable times and upon reasonable notice, to examine those records and all other material documents relating to or relevant to Net Sales, Pre-Commercialization Income and Post-Commercialization Income in the possession or control of ALTEON or its Affiliates, for a period of three years after such royalties have accrued, as may be necessary to: (i) determine the correctness of any report or payment made under this Agreement; or (ii) obtain information as to the royalties payable for any calendar semi-annual period in the case of ALTEON's failure to report or pay pursuant to this Agreement. Said accountant shall not disclose to WASHINGTON any information other than information relating to said reports, royalties, and payments. Results of any such examination shall be made available to ALTEON if a claim is made for royalties underpaid by ALTEON. WASHINGTON shall bear the full cost of the performance of any such audit, unless such audit demonstrates underpayment of royalties by ALTEON of more than ten percent (10%) from the amount of the original royalty payment made by ALTEON. In such event, ALTEON shall bear the full cost of the performance of such audit. 6.6 Taxes. In the event that ALTEON or its Affiliates are required to withhold any tax to the revenue authorities in any country in the Territory regarding any payment to WASHINGTON due to the laws of such country, such amount shall be deducted by ALTEON or its Affiliates, and it shall notify WASHINGTON and -13- 19 Exhibit 10.10 promptly furnish WASHINGTON with copies of any tax certificate or other documentation evidencing such withholding. ARTICLE 7 - OWNERSHIP; PATENT PROSECUTION 7.1 WASHINGTON Ownership. Except as otherwise provided in Section 7.2 or 7.3, WASHINGTON shall retain all right, title and interest in and to the Licensed Technology and the Licensed Patents, regardless of which party prepares and prosecutes the applications associated therewith, or maintains the patents, copyrights or other intellectual property rights related to the Licensed Technology or Licensed Patents, subject to the license granted to ALTEON under Section 4.1. Rights to Inventions made solely by employees of WASHINGTON using WASHINGTON's facilities shall belong to WASHINGTON. WASHINGTON agrees to promptly disclose to ALTEON any such Inventions. 7.2 ALTEON Ownership. Rights to Inventions made solely by employees of ALTEON using ALTEON's facilities shall belong to ALTEON. ALTEON agrees to promptly disclose to WASHINGTON any such Inventions. 7.3 Joint Ownership. Rights to Inventions which were made jointly during the performance of this Agreement by University Personnel or other inventors owing a duty to assign to WASHINGTON and by employees of ALTEON shall belong jointly to WASHINGTON and to ALTEON. Such Joint Inventions shall be subject to the terms and conditions of this Agreement. 7.4 Patent Prosecution and Maintenance. (a) WASHINGTON shall continue to have full responsibility for and shall control the preparation and prosecution of all patent applications and the maintenance of all patents related to the Licensed Technology and included in the Licensed Patents. WASHINGTON agrees to take all actions reasonably necessary to diligently prosecute and maintain any patents or patent applications in the countries listed on Exhibit C. ALTEON and WASHINGTON shall mutually determine the additional countries, if any, where patent applications will be filed and prosecuted, and where the patents will be maintained. The Parties acknowledge and agree that they intend for WASHINGTON to file and prosecute patent applications and maintain patents in all major commercial markets where viable use patent protection is available (such countries, including the countries listed on Exhibit C, shall be referred to as "Use Patent Countries"). If the laws affecting patent protection or maintenance costs change in any Use Patent Country, the Parties shall reassess the need to continue to file and prosecute patent applications and maintain patents in such country. If the Parties determine to discontinue such filing, prosecution and maintenance in any such country, such country shall no longer be deemed a Use Patent Country. (b) As of the Effective Date of this Agreement, ALTEON shall reimburse WASHINGTON for all reasonable fees and expenses (including, without limitation, legal fees, filing and maintenance fees or other governmental charges) incurred on or after January 1, 1995 in connection with the filing and prosecution of such patent applications and maintenance of such patents, including patent applications and patents relating to Inventions and Joint Inventions. In addition, ALTEON shall reimburse WASHINGTON for all such reasonable fees and expenses incurred prior to the Effective Date in connection with the filing of the continuation-in-part application to U.S. Patent #[C.I.], which was filed on [C.I.]. WASHINGTON shall provide ALTEON with copies of all detailed statements it receives from its counsel for legal fees and expenses for ALTEON's review. If ALTEON does not notify WASHINGTON or the person or entity -14- 20 Exhibit 10.10 rendering the services of any issues, questions or discrepancies regarding such statement within thirty (30) days after receipt of such statement by ALTEON, the fees and expenses set forth in such statement shall be deemed reasonable. (c) WASHINGTON shall select qualified independent patent counsel (who shall be reasonably acceptable to ALTEON) to file and prosecute all patent applications required pursuant to Section 7.4(a). ALTEON or its representatives shall be entitled to meet and confer with such patent counsel at reasonable times and places. WASHINGTON shall promptly provide copies to ALTEON of any communications from any patent office relating to the Licensed Technology, and allow ALTEON and its patent counsel the opportunity to attend (either in person or by phone) any conferences (conducted in person or by phone) to be made with or to any patent office regarding the Licensed Technology. In addition, filing deadlines permitting, at least thirty (30) days prior to the filing of any patent application, amendment thereto, or response to any patent office action related to the Licensed Technology, WASHINGTON shall provide ALTEON with a copy of each such patent application, amendment or response and will provide ALTEON and its legal counsel with an opportunity to consult with WASHINGTON and its patent counsel regarding the filing and contents of any such application, amendment or response, and the advice and suggestions of ALTEON and its legal counsel shall be taken into consideration by WASHINGTON and its legal counsel in connection with such filing. However, WASHINGTON shall make every reasonable effort to obtain the concurrence of ALTEON regarding the content of any patent application, amendment thereto, or response to any patent office action related to the Licensed Technology prior to filing or submitting same. WASHINGTON shall also provide ALTEON with copies of any patentability search reports made by patent counsel, including patents located, a copy of each patent application, and each patent that issues thereon. (d) WASHINGTON agrees to provide promptly to ALTEON complete written disclosure of any Invention made by WASHINGTON. ALTEON and WASHINGTON shall mutually determine whether such Invention is patentable. If the Parties determine that such Invention is patentable, WASHINGTON shall proceed with the preparation and prosection of a patent application covering such Invention. (e) If ALTEON elects not to support any patent or patent application in any Use Patent Country in the Territory, ALTEON shall notify WASHINGTON in a timely manner and WASHINGTON may do so at its own expense. In such event, such patent or application in such country shall be considered as part of the Licensed Patents, and ALTEON shall be required to pay royalties for Products which would infringe a Valid Claim of such patent in such Use Patent Country pursuant to Section 5.6. (f) In the event that the Parties elect to file one or more patent applications comprising Joint Inventions, the Parties shall confer on how the preparation and prosecution of such applications shall be accomplished. Once the Parties agree on how to proceed with respect to the preparation and filing of patent applications comprising Joint Inventions, all other provisions of this Section 7.4 shall govern such preparation, filing, maintenance and prosecution. (g) Both Parties, including all University Personnel who agree to participate in a Sponsored Research Program or an ALTEON Research Program and sign a copy of this Agreement, agree to cooperate with the other Party to execute all lawful papers and instruments, to make all rightful oaths and declarations and to provide consultation and assistance as may be necessary in the preparation, prosecution, maintenance, and enforcement of all such patent applications and patents. -15- 21 Exhibit 10.10 ARTICLE 8 - PATENT ENFORCEMENT; INFRINGEMENT 8.1 Notification of Infringement. If either Party learns of an infringement or other use, rights or ownership claim or threatened infringement or other such claim by a third party with respect to any Licensed Patent or other Licensed Technology granted hereunder within the Territory (an "Infringement"), such Party shall promptly notify the other Party and shall provide such other Party with available evidence of such infringement. 8.2 Patent Enforcement. ALTEON shall have the first right, but not the duty, to institute infringement actions against third parties based on any Infringement. If ALTEON does not institute an infringement proceeding against an offending third party within ninety (90) days after receipt of notice from WASHINGTON, WASHINGTON shall have the right, but not the duty, to institute such an action. The costs and expenses of any such action (including fees of attorneys and other professionals) shall be borne by the Party instituting the action, or, if the Parties elect to cooperate in instituting and maintaining such action, such costs and expenses shall be borne by the Parties in such proportions as they may agree in writing. Each Party shall execute all necessary and proper documents and take such actions as shall be appropriate to allow the other Party to institute and prosecute such infringement actions. Each Party shall consult with and co-operate with the other Party in good faith in the event that either Party is pursuing any such action. Any award paid by third parties as a result of such an infringement action (whether by way of settlement or otherwise) shall be paid to the Party who instituted and maintained such action, or, if both Parties instituted and maintained such action, such award shall be allocated among the Parties in proportion to their respective contributions to the costs and expenses incurred in such action. Notwithstanding the foregoing, either Party may participate in any such suit or action and use its own counsel at its own expense for such purpose. Both Parties, and their respective counsel, shall cooperate by sharing information concerning any such suit or action. 8.3 Infringement Action by Third Parties. (a) In the event of the institution of any suit by a third party against ALTEON for patent or other intellectual property rights infringement or other use, rights or ownership claim involving the use or sale of any Product in the Territory (an "Action"), ALTEON shall promptly notify WASHINGTON in writing of such Action. In the event that such an Action is instituted by a third party, neither Party shall take a position inconsistent with, or cooperate with or assist any third party who contests, WASHINGTON's ownership or the continued validity of any Licensed Patent or Licensed Technology. Each Party shall use its best efforts to consult with, support and cooperate with the other Party, in good faith, in the event that either Party is pursuing any such Action, including specifically, without limiting the generality of the foregoing, actively and vigorously contesting any third party claim challenging WASHINGTON's right to grant the rights granted herein to ALTEON. ALTEON shall have the right to defend such suit at its own expense, and WASHINGTON hereby agrees to assist and cooperate with ALTEON, at its own expense, to the extent necessary in the defense of such suit; provided, however, that WASHINGTON shall not be obligated to engage in any testing at its own expense. During the pendency of such action, ALTEON shall continue to make all payments due under this Agreement. Notwithstanding the foregoing, either Party may participate in any such suit or action and use its own counsel at its own expense for such purpose. Both Parties, and their respective counsel, shall cooperate by sharing information concerning any such suit or action. -16- 22 Exhibit 10.10 (b) If as a result of any judgment, award, decree or settlement resulting from an Action instituted by a third party, ALTEON is required to pay a royalty to such third party, ALTEON shall continue to pay running royalties for such Products in the country which is the subject of such Action, but shall be entitled to a credit against such payments in an amount equal to one-half (1/2) of the royalty paid to such third party, but in no event shall such credit be more than 50% of such royalties due hereunder for such Products in such country which is the subject of such Action in any calendar semi-annual period. In addition, if ALTEON is required to pay damages to such third party, and such damages are not otherwise reimbursed by WASHINGTON, ALTEON shall be entitled to a credit against such payments in an amount equal to one-half (1/2) of such damages, to the extent effectively paid by ALTEON to such third party, but in no event shall the total credit provided hereunder be more than 50% of such royalties due hereunder for such Products in such country which is the subject of such Action in any calendar semi-annual period. ARTICLE 9 - PUBLICATION; CONFIDENTIALITY 9.1 Notification. ALTEON acknowledges that the basic objective of research activities at WASHINGTON is the generation of new knowledge and its expeditious dissemination. However, both Parties also recognize the importance of acquiring patent protection on inventions. Consequently, any proposed Publication by University Personnel shall comply with this ARTICLE 9. At least fifteen (15) days before a manuscript is to be submitted to a publisher, University Personnel will provide ALTEON with a copy of the manuscript. If University Personnel wish to make an oral presentation, they will provide ALTEON with a copy of the abstract (if one is submitted) at least fifteen (15) days before it is to be submitted. University Personnel will also provide to ALTEON a copy of the text of the presentation, including all slides, posters, and any other visual aids, at least fifteen (15) days before the presentation is made. 9.2 Review of Proposed Publications. ALTEON will review the manuscript, abstract, text or any other material provided under Section 9.1 to determine if patentable subject matter is disclosed. ALTEON will notify University Personnel within fifteen (15) days of receipt of the proposed Publication if ALTEON, in its sole discretion, determines that patentable subject matter is or may be disclosed, or if ALTEON, in its sole discretion, believes confidential or proprietary information is or may be disclosed. If it is determined by ALTEON that patent applications should be filed, the University Personnel shall delay its publication or presentation for a period not to exceed ninety (90) days from ALTEON's receipt of the proposed Publication to allow time for the filing of patent applications covering patentable subject matter. In the event that the delay needed to complete the filing of any necessary patent application will exceed the ninety (90) day period, WASHINGTON and University Personnel will discuss with ALTEON the need for obtaining an extension of the publication delay beyond the ninety (90) day period. The publication delay shall not exceed 105 days from the date that the proposed Publication was first submitted to ALTEON for review, except that, by mutual agreement, as provided in this Section, this delay may be extended past the 105 day period for purposes of filing patent applications. If it is determined by ALTEON and WASHINGTON that confidential or proprietary information is being disclosed, ALTEON, WASHINGTON and University Personnel will consult among themselves in good faith to arrive at an agreement on mutually acceptable modifications to the proposed Publication to avoid such disclosure. 9.3 Use of Name. WASHINGTON agrees not to use directly or indirectly ALTEON's name without ALTEON's prior written consent except that WASHINGTON may -17- 23 Exhibit 10.10 acknowledge ALTEON's funding of any Sponsored Research Programs in scientific publications and in listings of Sponsored Research Programs. ALTEON agrees not to use directly or indirectly WASHINGTON's name, the name of any Investigator or University Personnel, or the name of any trustee, officer, faculty member, student or employee thereof, without WASHINGTON's prior written consent, except that ALTEON may refer to any University Personnel who is serving as a member of ALTEON's Scientific Advisory Board or as a consultant to ALTEON and include a statement of his experience and qualifications and his current and past positions at WASHINGTON. Notwithstanding the foregoing, ALTEON and WASHINGTON may include an accurate description of the terms of this Agreement to the extent required under federal or state securities or other disclosure laws and internal communications; and ALTEON may use WASHINGTON's name in various documents used by ALTEON for capital raising and financing purposes, provided that WASHINGTON grants prior written approval of such use, which approval shall not be unreasonably withheld. WASHINGTON agrees that ALTEON's use of its name solely to identify this Agreement will be deemed a reasonable use by WASHINGTON for which it grants its approval. 9.4 Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that, for the term of this Agreement and for five years thereafter, the receiving Party shall keep completely confidential and shall not publish or otherwise disclose and shall not use for any purpose any information furnished to it by the other Party pursuant to this Agreement, except to the extent that it can be established by the receiving Party by competent proof that such information: (a) was already known to the receiving Party, other than under an obligation of confidentiality, at the time of disclosure by the other Party; (b) was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party; (c) became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement; (d) was disclosed to the receiving Party, other than under an obligation of confidentiality, by a third party who had no obligation to the disclosing Party not to disclose such information to others; or (e) was independently developed by or for the receiving Party by persons not having access to such information. Each Party may disclose the other's information to the extent such disclosure is reasonably necessary in filing or prosecuting patent applications, prosecuting or defending litigation, complying with applicable governmental regulations, undertaking basic research with outside collaborators, or conducting preclinical or clinical trials, provided that if a Party is required to make any such disclosure of the other Party's secret or confidential information it will, except where impracticable for necessary disclosures, for example to physicians conducting studies or to health authorities, give reasonable advance notice to the other Party of such disclosure requirement and, except to the extent inappropriate in the case of patent applications, will use its best efforts to secure confidential treatment of such information required to be disclosed. 9.5 Confidentiality Agreements with University Personnel. Prior to any University Personnel participating in any Sponsored Research Program or any ALTEON Research Program in any manner or receiving any test data, clinical -18- 24 Exhibit 10.10 information or any other information relating to or resulting from any Sponsored Research Program or any ALTEON Research Program which is deemed a trade secret or confidential or proprietary to ALTEON or WASHINGTON, WASHINGTON shall cause such University Personnel to execute a confidentiality and non-disclosure agreement with ALTEON in the form attached as Exhibit D. ARTICLE 10 - INDEMNIFICATION 10.1 Indemnification. ALTEON shall defend, indemnify and hold WASHINGTON, its directors, trustees, faculty members, officers and employees, harmless from and against any and all third party claims, suits or demands, threatened or filed, ("Claims") for liability, damages, losses, costs and expenses (including the costs and expenses of attorneys and other professionals), at both trial and appellate levels, relating to the distribution, testing, manufacture, use, sale, consumption, applications, or injection of Products by ALTEON, its Affiliates or its sublicensees pursuant to this Agreement, including, without limitation, Claims for any loss, damage, or injury to persons or property, or loss of life, or relating to the promotion and advertising of Products and/or interactions and communications with governmental authorities, physicians or other third parties. The foregoing indemnification shall not apply to any Claims to the extent caused by either the acts or omissions of WASHINGTON or any University Personnel. 10.2 Notice. In the event that WASHINGTON seeks indemnification under Section 10.1, WASHINGTON agrees to: (i) promptly inform ALTEON of any Claim, (ii) permit ALTEON to assume direction and control of the defense or claims resulting therefrom (including the right to settle it at the sole discretion of ALTEON), and (iii) cooperate as reasonably requested (at the expense of ALTEON) in the defense of the Claim. Notwithstanding the foregoing, WASHINGTON shall have the right to participate in the defense or prosecution of any Claim, including hiring its own counsel at its own expense, and ALTEON shall cooperate with WASHINGTON if WASHINGTON does so participate. 10.3 Insurance. ALTEON shall at all times comply with all statutory worker's compensation and employer's liability requirements covering any and all employees with respect to activities performed under this Agreement. In addition to the foregoing, ALTEON shall obtain and maintain the following: (a) Prior to the first human clinical trials of a Product under this Agreement, broad form comprehensive general liability insurance with a reputable and financially secure insurance carrier, to cover such activities of ALTEON and ALTEON's contractual indemnity under this Agreement.
