STATEMENTS AND REMITTANCES 9.01 LICENSEE shall keep and require its AFFILIATES and sublicensees to keep complete and accurate records of all sales of VACCINE and COMBINATION under the licenses granted herein. LICENSOR shall have the right, at LICENSOR's expense, through a certified public accountant or like person reasonably acceptable to LICENSEE, to examine such records during regular business hours during the life of this Agreement and for six (6) months after its termination; provided, however, that such examination shall not take place more often than once a year and shall not cover such records for more than the preceding two (2) years and provided further that such accountant shall report to LICENSOR only as to the accuracy of the royalty statements and payments.

TERM AND TERMINATION 10.01 Unless otherwise terminated, this Agreement shall expire upon the expiration, lapse or invalidation of the last remaining PATENT in the TERRITORY. Expiration of this Agreement under this provision shall not preclude LICENSEE from continuing to market VACCINE and to use KNOW-HOW without any further royalty or other payments to LICENSOR. 10.02 If either party fails or neglects to perform covenants or provisions of this Agreement and if the party in default has not corrected such default within sixty (60) days (the period shall be thirty (30) days for a payment default) after receiving written notice from the other party with respect to such default, such other party shall have the right to terminate this Agreement by giving written notice to the party in default provided the notice of termination is given within six (6) months of the default and prior to correction of the default.

PATENTS for the research, development, making, using or selling of any product or process, including, but not limited to, VACCINES. 12. WARRANTIES AND REPRESENTATIONS 12.01 LICENSOR warrants that it has the right to grant the rights and licences under PATENTS and KNOW-HOW as provided throughout this Agreement including, but not limited to, the Rotavirus 89.12 strain and that it has the right to enter into this Agreement. 12.02 Nothing in this Agreement shall be construed as a warranty that PATENTS are valid or enforceable or that their exercise does not infringe any patent rights of THIRD PARTIES. Without having made an investigation or search, LICENSOR hereby warrants and represents that it has no present knowledge from which it can be inferred that PATENTS are invalid or that their exercise would infringe patent rights of THIRD PARTIES or that the Rotavirus 89.12 strain or the use thereof in VACCINE infringes any patent rights of THIRD PARTIES. Subject to other provisions contained herein, a holding of invalidity or unenforceability of any PATENT, from which no further appeal is or can be taken, shall not affect any obligation already accrued hereunder, but shall only eliminate royalties otherwise due under such PATENT from the date such holding becomes final. 12.03 LICENSOR acknowledges that, in entering into this Agreement, LICENSEE has relied upon technical and clinical information and KNOW-HOW disclosed and/or supplied by or on behalf of LICENSOR and that LICENSEE has relied upon LICENSOR's obligation to disclose and/or supply further information pursuant to Paragraph(s) 6.01 and/or 6.02 hereof.

LICENSOR warrants and represents that it will use its reasonable efforts to review the technical and/or clinical information and/or KNOW-HOW to be disclosed and/or supplied to LICENSEE under Paragraph(s) 6.01 and/or 6.02 hereof after the date of this Agreement for any inaccuracies therein and that, to the extent LICENSOR has any knowledge of any material inaccuracies in such technical and/or clinical information and/or KNOW-HOW, it shall inform LICENSEE of such inaccuracies. LICENSOR and LICENSEE warrant and represent to each other that they have not, up to the date of this Agreement, omitted to disclose and/or supply to each 23. other any information known to them concerning VACCINE or the transactions contemplated by this Agreement which would, to the best of their knowledge, be material to the other's decision to enter into this Agreement and to undertake the commitments and obligations set forth herein. 12.04 LICENSOR warrants and represents that it has no present knowledge of the existence of any pre-clinical or clinical data or information concerning VACCINE which suggests that there may exist toxicity, safety and/or efficacy concerns which may materially impair the utility and/or safety of VACCINE. 13. FORCE MAJEURE 13.01 If the performance of any part of this Agreement by either party, or of any obligation under this Agreement other than a payment provision, is prevented, restricted, interfered with or delayed by reason of any cause beyond the reasonable control of the party liable to perform, unless conclusive evidence to the contrary is provided, the party so affected shall, upon giving written notice to the other party, be excused from such performance to the extent of such prevention, restriction, interference or delay, provided that the affected party shall use its reasonable best efforts to avoid or remove such causes of non-performance and shall continue performance with the utmost dispatch whenever such causes are removed. When such circumstances arise, the parties shall discuss what, if any, modification of the terms of this Agreement may be required in order to arrive at an equitable solution.

If the parties have not resolved the dispute amicably, legal action may be introduced. 16. SEPARABILITY 16.01 In the event any portion of this Agreement shall be held illegal, void or ineffective, the remaining portions hereof shall remain in full force and effect. 16.02 If any of the terms or provisions of this Agreement are in conflict with any applicable statute or rule of law, then such terms or provisions shall be deemed inoperative to the extent that they may conflict therewith and shall be deemed to be modified to conform with such statute or rule of law. 16.03 In the event that the terms and conditions of this Agreement are materially altered as a result of Paragraphs 16.01 or 16.02, the parties will renegotiate the terms and conditions of this Agreement to resolve any inequities. 17.

NO WAIVER 18.01 The failure of either party at any time to exercise any of their respective rights under this Agreement shall not be deemed a waiver thereof, nor shall such failure in any way prevent either party, as the case may be, from subsequently asserting or exercising such rights. 19.

VRI may delete from copies of sublicense agreements provided to GAMBLE hereunder commercial, research and development, manufacturing, financial and other provisions unrelated to VRI's or the Sublicensee's obligations to Gamble. 8. INDEMNIFICATION AND INSURANCE. 8.1 VRI shall defend, indemnify and hold harmless GAMBLE and its trustees, officers, medical and professional staff, employees, and agents and their respective successors, heirs and assigns against all losses, damages, expenses, including attorney's fees and against any claims, suits, actions, demands or judgments brought against any one or more of them, arising out of any theory of product liability (including, but not limited to, action in the form of tort, warranty, or strict liability) or negligence concerning any product, process or service made, used or sold pursuant to any right or license granted under this AGREEMENT. VRI shall have the right to control the defense settlement and/or compromise of any such claims or actions. 8.2 VRl's obligations under Section 8.1 above shall not apply to any liability, damage, loss or expense to the extent that it is directly attributable to the negligence or intentional misconduct of GAMBLE or any of its trustees, officers, medical and professional staff, employees, agents or their respective successors, heirs or assigns. 8.3 VRI shall add, at VRl's expense, GAMBLE as an additional insured on VRI's clinical trial insurance policy, which provides limits of liability of $2,000,000 per incident and aggregate, effective upon the Effective Date of this AGREEMENT, to provide insurance coverage for GAMBLE for the clinical trials. 8.4 VRI, at VRl's expense, shall maintain policies of comprehensive general liability insurance and will obtain product liability insurance in amounts not less than $1,000,000 per incident and $2,000,000 annual aggregate and shall add GAMBLE as an additional insured on VRI's policy, which provides such limits of liability.

VRI shall maintain such comprehensive general liability insurance and product liability insurance beyond the expiration or termination of this AGREEMENT and for a reasonable period after the termination of the clinical trials, which in no event shall be less than fifteen (15) years after the clinical trials. 8.5 This Section 8 shall survive expiration or termination of this AGREEMENT. 10. CONFIDENTIALITY 10.1 CONFIDENTIAL INFORMATION.

"Confidential Information" means information of any type, not generally known, about the business, processes, services, products, suppliers, customers, clients or plans of GAMBLE or VRI ("the parties hereto") of any client of the parties hereto (regardless of whether the parties hereto have executed a confidentiality agreement with such customer), which is used or useful in the conduct of business of the parties hereto, or which confers or tends to confer a competitive advantage over one who does not possess such information. Such information includes, but is not limited to, information relating to trade secrets, Technical Information, patent applications, know-how, research, development, design, engineering, quality control or service techniques, information about existing, new or envisioned products, processes or services and their development, performance, scientific, engineering or technical information, laboratory notebooks, notes, computer programs, source codes, object codes, software manuals, sketches, drawings, reports, formulae, gels, slides, sequences, biological materials living or otherwise, photographs, negatives, prototypes, models, correspondence, and other documents and things, and information relating to purchasing, sales, marketing, licensing, contracts with third parties, and pricing, whether or not in writing and whether or not labeled or identified as confidential or proprietary. Confidential Information may be disclosed in writing or orally or may be obtained by observation or inspection.

Without prior written consent, the parties hereto will not disclose the other party's Confidential Information to any third party other than employees, agents or others of the parties hereto who must necessarily be informed thereof, but only if and to the extent that any such person has a need for such information. A party hereto will only use Confidential Information for the purpose of fulfilling its obligations under this AGREEMENT. The parties hereto agree that they will take such reasonable steps as may be necessary to prevent the disclosure or use of any such materials by their officers, employees or agents except as provided herein, including but not limited to obtaining and enforcing appropriate confidentiality agreements with such persons. All obligations of confidentiality and nondisclosure set forth in this AGREEMENT shall survive the termination or expiration of this AGREEMENT. 10.3 The parties agree that clinical trial data generated by GAMBLE under the terms of the AGREEMENT will not be published by VRI prior to its publication by GAMBLE's principal investigators. To the extent not published, the results of the clinical trials will be held in confidence by GAMBLE.
