DEFINITIONS

1.1 “Affiliate” of an entity shall mean any entity that controls, is controlled by, or is under common control with such entity.

1.2 “Confidential Information” shall mean all written information and data provided by one Party to the other hereunder and marked “Confidential” or a reasonable equivalent thereof or, if disclosed orally, visually or in some other form, is summarized in a writing identified as “Confidential” or a reasonable equivalent thereof and provided to the other Party within thirty (30) days of such disclosure; provided, however, that during the term of this Agreement, the Prometheus Know-how shall be deemed the Confidential Information of both Parties. Notwithstanding the foregoing, Confidential Information of a Party shall not include information that the other Party (the “recipient”) can demonstrate:

(a) is known to the recipient and not subject to prior confidentiality obligations to Prometheus (i.e., knowledge of former Prometheus employees), as evidenced by its written records, before receipt thereof under this Agreement;

(b) is disclosed to the recipient without restriction after acceptance of this Agreement by a Third Party who has the right to make such disclosure;

(d) is independently developed, as evidenced by its written records, by or for the recipient by individuals or entities who have not had access to the information disclosed hereunder.

Provided, however that such right and license shall not include the right to promote any Licensed Products to gastroenterologists or to directly or indirectly, participate in the development or commercialization of any Licensed Product for use in diagnosing or treating any gastrointestinal diseases. Proprius shall have the exclusive right (even as to Prometheus) to publicly disclose or use Prometheus Know-how in support of Proprius’ and its Sublicensees’ development and commercialization efforts related to Licensed Products.

2.2 Sublicensing. [***] agrees that any agreement for the sublicense of any rights granted to it under this Article 2 [***] shall promptly provide [***] with a copy of each sublicense granted hereunder.

property of Prometheus, will be used only by Proprius and its Sublicensees in furtherance of the development and commercialization of Licensed Products, and only in a manner consistent with the protocol originally submitted to, and approved by, the respective IRBs of the institutions through which the Samples were collected. Prometheus shall provide to Proprius true and complete copies of each such protocol and a description of the Samples to which such protocol applies. The Samples supplied under this Section 2.3 must be used with prudence and appropriate caution in any experimental work, because not all of their characteristics may be known. THE SAMPLES ARE PROVIDED “AS IS” AND WITHOUT ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR ANY PARTICULAR PURPOSE OR ANY WARRANTY THAT THE USE OF THE SAMPLES WILL NOT INFRINGE OR VIOLATE ANY PATENT OR OTHER PROPRIETARY RIGHTS OF ANY THIRD PARTY. NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, PROMETHEUS SHALL HAVE NO LIABILITY (INCLUDING BUT NOT LIMITED TO DIRECT, INDIRECT, CONSEQUENTIAL OR EXEMPLARY) TO PROPRIUS RELATING TO THE SAMPLES REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH LIABILITY OR DAMAGES.

2.4 No Implied Rights. Proprius shall have no licenses or other rights other than those expressly granted in this Agreement, and, in particular and without limiting the foregoing, nothing in this Agreement shall be construed to grant Proprius any licenses or other rights in any intellectual property rights, information or data owned or controlled by Prometheus or any of its Affiliates, except as expressly set forth in this Agreement.

2.5 Restrictions on Development and Commercialization of Licensed Products. Notwithstanding any other provision of this Agreement, during the term of this Agreement, Proprius (and its Affiliates and Sublicensees) agrees that it will not, directly or indirectly, market or promote the Licensed Products to gastroenterologists nor will it (or any of its Affiliates or Sublicensees), directly or indirectly, participate in the development or commercialization of any Licensed Product for use in diagnosing or treating any gastrointestinal diseases.

2.6 Right of First Negotiation. If, during the two (2) year period beginning on the First Commercial Sale of a Licensed Product by Proprius, (i) Proprius desires to divest or sublicense all or substantially all of its business relating to the Licensed Products (whether by sale, license or otherwise) to a Third Party, or (ii) a Third Party initiates such discussions with Proprius and Proprius is interested in entertaining such discussions (both (1) and (ii) are collectively referred to as a “Business Opportunity”), then Proprius will promptly notify Prometheus in writing thereof, with such notice containing a reasonably complete summary of reasonably available information necessary to evaluate the Business Opportunity; provided, however, that Proprius shall not be obligated to disclose to Prometheus the identity of any such Third Party, the terms proposed by such Third Party (if confidential) or any other confidential or proprietary information of such Third Party. If Prometheus indicates interest in pursuing the Business Opportunity within [***] business days of Prometheus’ receipt of Proprius’ written notice, the Parties will negotiate in good faith to enter into a definitive agreement. If the Parties are unable to enter into a definitive agreement within [***] days after Proprius’ receipt of Prometheus’ indication of interest, or if Prometheus does not so indicate an interest in pursuing the Business Opportunity within the [***] business day period, Proprius will be free to execute such Business Opportunity with a Third Party provided that Proprius shall not offer the Business Opportunity to a Third Party on terms more favorable then those offered to Prometheus or on terms worth less to Proprius then those offered by Prometheus for the Business Opportunity. In no event shall Proprius be obligated to enter into any such transaction with Prometheus. Notwithstanding anything in this Agreement to the contrary, any Business Opportunity entered into by Proprius with a Third Party will be subject to Prometheus’ rights under this Agreement, including, without limitation, Prometheus’ right to receive the payments set forth in Article 5.

5.7 Terms of Payment.

(a) Within [***] days following the end of each Contract Quarter during the Term, Proprius shall make the payments to Prometheus set forth in Sections 5.4 of this Agreement based on Net Sales during the previous Contract Quarter.

(d) All royalty and milestone and Sublicense Royalties and Sublicense Fee payments due Prometheus shall be made in United States dollars by wire transfer to a bank and account specified by Prometheus in writing. For sales made or Sublicense Fees or Sublicensee Royalties received in currency other than United States dollars, amounts payable under this Agreement shall be converted to United States dollars as would be required for reporting under GAAP. In no event shall the applicable royalties exceed the maximum amount payable under the applicable laws, regulations or administrative rulings of the territory or country which restricts the royalty rate or amount payable on Net Sales in such territory or country.

5.8 Taxation of Royalties. Where any sum due to be paid to Prometheus hereunder is subject to any withholding or similar tax, the Parties shall use reasonable efforts to do all such acts and things and to sign all such documents as will enable them to take advantage of any applicable double taxation agreement or treaty or appeal procedure. In the event there is no applicable double taxation agreement or treaty, or appeal procedure, or if any appeal procedure has been exhausted or if an applicable double taxation agreement or treaty or appeal procedure reduces but does not eliminate such withholding or similar tax, notwithstanding any pending appeal, Proprius shall pay such withholding or similar tax to the appropriate government authority as may be required, deduct the amount paid from the amount due Prometheus and secure and send to Prometheus reasonable evidence of such payment.

5.9 Restrictions on Remittance. If, at any time, legal restrictions prevent the prompt remittance of part or all royalties with respect to any country where Licensed Products are sold, Proprius shall have the right to make such payments by depositing the amount thereof in local currency to Prometheus’ account in a bank or other depository institution in such country.

5.10 Late Payments. Any payment, including without limitation, royalty, Sublicense Fees, Sublicensee Royalties, and milestone payments, made by Proprius under this Agreement after the date such payment is due shall bear interest at the lesser of 1 1/2% per month and the maximum rate permitted by applicable law.

BOOKS AND RECORDS

6.1 Procedures. Proprius shall keep full and accurate accounting records of Net Sales, Sublicense Fees and Sublicensee Royalties in sufficient detail to determine the amounts payable to Prometheus under Sections 5.3, 5.4 and 5.5. Such records, together with all necessary supporting data, shall be kept at Proprius’ offices at the address set forth above or such other address as Proprius may indicate in writing to Prometheus.

-11-

amount that was payable for such period, then Proprius shall, in addition to paying any such deficiency, reimburse Prometheus for the cost of such audit.

6.3 Period to be Kept. Proprius shall retain all books and records it is required to maintain under Section 6.1 for [***] from the end of the Contract Year of the Net Sales (or Sublicense Fees or Sublicensee Royalties) to which the books and records pertain.
