In the event that during the Royalty Term, 454 is required (a) to enter into any agreement with any Third Party to obtain a license to an issued patent or patents in the absence of which the sale of a Royalty-Bearing Service would cause it to infringe such patent in a given country (each, a “Third Party Agreement”) and (b) to make royalty payments under such Third Party Agreements, then, solely to the extent the royalties paid under such Third Party Agreements exceed [************], the royalties due to CuraGen pursuant to Section 2.5.1 above for such Royalty-Bearing Service may be reduced by [************] of the amount by which such royalty payments exceed [************]; provided, that, any such reductions under this Section 2.5.2 shall in no event reduce the royalty for such Royalty-Bearing Service in any such country payable pursuant to Section 2.5.1 above to less than [************].

2.5.3 Royalty Term. 454 shall pay royalties with respect to each Royalty-Bearing Service on a country-by-country basis commencing on the date of First Commercial Sale of such Royalty-Bearing Service until and continuing to the later of (a) the last-to-expire of the Core Patent Rights whose claims cover the manufacture, use or sale of such Royalty-Bearing Service in such country, or (b) [***********] years from the First Commercial Sale of such Royalty-Bearing Service in such country (the “Royalty Term”). Following such Royalty Term, 454 shall have a fully paid-up, irrevocable, freely transferable and sublicensable license in such country under the relevant Core Patent Rights and Core Technology, to develop, have developed, make, have made, use, have used, sell, have sold, offer for sale, import and have imported such Royalty-Bearing Service in such country. The parties hereby acknowledge and agree that (a) royalties may be payable hereunder for a Royalty-Bearing Service for which no Core Patent Rights exist or for which no license is granted by CuraGen and (b) under such circumstances, such royalties shall be in consideration of the commercial advantage and background information gained from the license hereunder.

2.5.4 Payment Terms.

(a) Timing of Payments. 454 shall make all royalty payments owed to CuraGen in United States Dollars, quarterly within thirty (30) days following the end of each calendar quarter for which such royalties are deemed to occur (as provided in the next sentence), using the wire transfer provisions of this Section 2.5.4. For purposes of determining when a sale of any Royalty-Bearing Service occurs under this Agreement, the sale shall be deemed to occur on the earlier of (a) the date the Royalty-Bearing Service is shipped or provided, as the case may

be or (b) the date of the invoice to the purchaser of the Royalty-Bearing Service. Each royalty payment shall be accompanied by a report for each country in which sales of Royalty-Bearing Services occurred in the calendar quarter covered by such statement, specifying: the gross sales (if available) and Net Sales in each country’s currency; the applicable royalty rate under this Agreement; the royalties payable in each country’s currency, including an accounting of deductions taken in the calculation of Net Sales; the applicable exchange rate to convert from each country’s currency to United States Dollars under this Section 2.5.4; and the royalties payable in United States Dollars.

(b) Foreign Currency Exchange. All royalties shall be payable in full in the United States in United States Dollars, regardless of the countries in which sales are made. For the purpose of computing Net Sales for Royalty-Bearing Services sold in any currency other than United States Dollars, the quarterly royalty payment will be calculated as follows:

(A/B) x C = United States Dollars royalty payment on foreign sales, where

A =

foreign “Net Sales” (as defined above) per quarter;

B =

foreign exchange conversion rate, expressed in local currency per United States Dollar (using as the applicable foreign exchange rate the average of the rate published in the western edition of The Wall Street Journal, or any other mutually agreed upon source, for the last business day of the calendar quarter); and

C =

the royalty rate applicable to such Net Sales under this Agreement.

(c) Tax Withholding; Restrictions on Payment. All payments hereunder shall be made free and clear of any taxes, duties, levies, fees or charges, except for withholding taxes (to the extent applicable). 454 shall make any applicable withholding payments due on behalf of CuraGen and shall promptly provide CuraGen with written documentation of any such payment sufficient to satisfy the requirements of the United States Internal Revenue Service relating to an application by CuraGen for a foreign tax credit for such payment. If by law, regulations or fiscal policy of a particular country, remittance of royalties in United States Dollars is restricted or forbidden, written notice thereof shall promptly be given to CuraGen, and payment of the royalty shall be made by the deposit thereof in local currency to the credit of CuraGen in a recognized banking institution designated by CuraGen by written notice to 454. When in any country the law or regulations prohibit both the transmittal and the deposit of royalties on sales in such country, royalty payments shall be suspended for as long a such prohibition is in effect and as soon as such prohibition ceases to be in effect, all royalties that 454 would have been under an obligation to transmit or deposit but for the prohibition shall forthwith be deposited or transmitted, to the extent allowable.

(d) Wire Transfers. All payments hereunder shall be made to CuraGen by bank wire transfer in immediately available funds to the account designated by CuraGen by written notice to 454 from time to time.

2.5.5 Overdue Royalties. All royalties not paid within the time period set forth in this Article 2 shall bear interest at a rate of [************] per month from the due date until paid in full.

2.5.6 Records Retention; Review.

(a) Royalties. 454 and its Affiliates and/or sublicensees shall keep for at least three (3) years from the end of the calendar year to which they pertain complete and accurate records of sales by 454, or its Affiliates and/or sublicensees, as the case may be, of each Royalty-Bearing Service, in sufficient detail to allow the accuracy of the royalties to be confirmed.

(b) Review. At the request of CuraGen, upon at least [************] days prior written notice from CuraGen (except as otherwise provided herein), 454 shall permit an independent certified public accountant reasonably selected by CuraGen and reasonably acceptable to 454 to inspect (during regular business hours) the relevant records required to be maintained by 454 under this Section 2.5.6. At CuraGen’s request (which shall not be made more frequently than once per year during the term), the accountant shall be entitled to review the then-preceding three (3) years of 454’s records under this Section 2.5.6 for purposes of verifying 454’s royalty calculations. In every case the accountant must have previously entered into a confidentiality agreement with both parties substantially similar to the provisions of Article 4 and limiting the disclosure and use of such information by such accountant to authorized representatives of the parties and the purposes germane to this Section 2.5.6. Results of any such review shall be made available to both parties and shall be binding on both parties. CuraGen agrees to treat the results of any such accountant’s review of the 454’s records under this Section 2.5.6 as Confidential Information of 454 subject to the terms of Article 4. If any review reveals a deficiency in the calculation of royalties resulting from any underpayment by 454, 454 shall promptly pay CuraGen the amount remaining to be paid (plus interest thereon at the rate provided in Section 2.5.5 above), and if such underpayment is by [************] or more, 454 shall pay all costs and expenses of the review.

2.6 Early Access to Royalty-Bearing Services. In partial consideration of the rights granted to it hereunder, 454 hereby agrees for a period of not less than [*******] months prior to the provision by it of any Royalty-Bearing Service and/or the shipment by it to any Third Party of an Instrument that provides a Royalty-Bearing Service, it will first offer such Royalty-Bearing Service exclusively to CuraGen, under either the Beta Site Agreement or under a separate agreement, as the case may be, on the terms set forth on Schedule C attached hereto and such additional terms as may be mutually acceptable to the parties.

2.7 Approval of Certain Contracts. Notwithstanding anything to the contrary contained in this Agreement, 454 hereby agrees that during the period commencing on the Restated Effective Date and continuing through [***********************], without the prior written approval of CuraGen, it shall not enter into any agreement (a) [*****************************************

********************************************************************] or (b) [*****************************

****************************************************************] or (c) [*******************************

******************************************]. 454 hereby further agrees that CuraGen may withhold any approval under subsection (a) above if CuraGen determines, (i) [**************************************************************

********************************************************]

or (ii) [************************************************************************ **************************].

2.8 Sales to Human Health Care Companies. The Parties hereby agree that during the period commencing on the Restated Effective Date and continuing through the [****************************] all promotional activities by 454 with respect to human health care companies shall be performed in accordance with Schedule D attached hereto.

2.9 Sequencing Services for CuraGen. 454 hereby agrees that it shall perform any Sequencing Services that CuraGen may request in writing from time to time during the term of this Agreement either for itself or as part of a collaboration at its fully-burdened cost. Any collaboration work that is solely Sequencing Services (to which CuraGen consents) will be priced at market and 454 will pay CuraGen the Section 2.5 royalty.

The Recipient shall use the Proprietary Materials only in compliance with all applicable federal, state, and local laws and regulations. The Recipient shall not transfer any Proprietary Materials to any third party without the prior written consent of the Supplier, except as expressly permitted hereby. Upon the expiration or termination of this Agreement, the Recipient shall at the instruction of Supplier either destroy or return any unused Proprietary Materials, which is not the subject of the grant of a continuing license hereunder.

4.4. Publicity. Neither party may publicly disclose the terms of this Agreement without the prior written consent of the other party; provided, however, that either party may make such a disclosure to the extent required by law or by the requirements of any nationally recognized securities exchange, quotation system or over-the-counter market on which such party has its securities listed or traded.

If 454 determines that enforcement of the parties’ rights in the Core Technology is appropriate, 454 shall have the right, but not the obligation, at its own expense, to take appropriate action to enforce such right; provided, however, that if 454 elects to so act, CuraGen shall have the right to participate in such enforcement by agreeing to bear a percentage of the costs of such enforcement in such amount as the parties shall determine not to exceed [************]. All amounts recovered in any action to enforce the parties’ rights in the Core Technology undertaken by 454 and CuraGen, whether by judgment or settlement, shall be retained by 454 and CuraGen pro rata according to the respective percentages of expenses borne by them in enforcing their rights to the Core Technology rights. If, within a reasonable period of time after notice of such infringement or breach, 454 has not commenced action to enforce such rights or thereafter ceases to pursue diligently such action, CuraGen shall have the right, but not the obligation at its expense, to take appropriate action to enforce such rights as its sole remedy hereunder.
