2.3.1. Rights in Other Fields. Unless prohibited by confidentiality obligations to Third Parties and
subject to any restrictions provided herein or in the Certificate of Incorporation of CuraGen, if either party becomes aware of the potential use in Other Fields of Core Technology, it shall promptly advise the other party of said use and provide a
summary of the information in its possession relating to such potential use. In the event that either party wishes to develop or commercialize any such Core Technology for any use in such Other Field, it shall first provide written notice to the
other party and shall offer the other party the right of first negotiation described in Section 2.3.2 hereof.



2.3.2. Right of First Negotiation. In the event that either party has a right of first negotiation as provided in Section 2.3.1,
the other party (the Offering Party) shall give written notice to the party having such right (the Receiving Party) specifying in reasonable detail the Other Field in which the Offering Party intends to develop and
commercialize the Core Technology and the uses within the Other Field for which the Offering Party intends to develop and commercialize such Core Technology (the Offer). The Receiving Party shall have [*********] days after the date of
the Offer to provide a written response to the Offering Party (the Response) as to whether or not it wishes to enter into negotiations with the Offering Party with respect to such rights. If the Response states that the Receiving Party
wishes to enter into negotiations with the Offering Party, the parties shall negotiate in good faith the licensing of such rights to such Core Technology for a period of [*********] days from the date of the Response. If the Response is not received
within the [*********] day response period or if the Receiving Party declines to enter into negotiations or if the parties do not agree upon and execute a written agreement within the [*********] day negotiation period, as such period may be
extended by written agreement of both parties, the Offering Party shall thereafter have the right, alone or in collaboration with a Third Party, to pursue development, commercialization or licensing of the Core Technology in such Other Field and for
the uses which were the subject of the Offer.



2.4 Corporate Opportunity. 454 hereby acknowledges that CuraGen has certain rights (a) under Section 2.3.1 hereof, to conduct business under certain conditions in Other Fields, and (b) under Section 1.1 of the Beta Agreement to
conduct business within the 454 Field, and hereby agrees that if CuraGen or any director or officer of 454 who is a director, officer or employee of CuraGen acquires knowledge of any potential transaction or matter which may be a Corporate
Opportunity or otherwise is then exploiting any Corporate Opportunity (whether such Corporate Opportunity is in the 454 Field, the CuraGen Field or Other Fields), 454 shall have no interest in, and no expectation that, such Corporate Opportunity be
offered to it, any such interest or expectation being hereby renounced so that CuraGen and such individuals (1) shall have no duty to communicate, or present such Corporate Opportunity to 454, shall have the right to hold any such Corporate
Opportunity for CuraGens (and its officers, directors, agents, stockholders, members, partners, Affiliates or Subsidiaries) own account, or to recommend, assign or otherwise transfer such
Corporate Opportunity to persons other than 454 or any Subsidiary of 454, and (2) cannot be liable to 454 or its stockholders for breach of any fiduciary duty as a stockholder, officer or director of 454 or otherwise by reason of the fact that
CuraGen pursues or acquires such Corporate Opportunity for itself, directs, sells, assigns or otherwise transfers such Corporate Opportunity to another person, or does not communicate information regarding such Corporate Opportunity to 454. For
purposes of this Section 2.4, Corporate Opportunity shall

mean an investment or business opportunity or prospective economic or competitive advantage in which 454 could, but for the provisions of this Section 2.4,
have an interest or expectancy.



2.5 Royalties on Sales of
Royalty-Bearing Services.



2.5.1
Royalties; Accounting. In consideration of the grant of the license by CuraGen hereunder, and subject to the other terms of this Agreement, commencing on the date of First Commercial Sale of any Royalty-Bearing Service and continuing for the
remainder of the Royalty Term, 454 shall pay to CuraGen a royalty of [********] of the total Net Sales of all Royalty-Bearing Services sold by 454 and/or its Affiliates and/or its sublicensees.



2.5.2 Third Party Royalty Offset. 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) [**************************************************************
