For purposes of determining when a sale of any Licensed Product occurs under this Agreement, the sale shall be deemed to occur on the later of: (i) the date the Licensed Product is shipped; or (ii) the date of the invoice to the purchaser of the Licensed Product. After the First Commercial Sale, all royalty payments shall be made within [***] ([***]) [***] after the end of each calendar quarter in which such sales were deemed to occur. Such royalty payments shall be accompanied by a detailed statement for each country in which sales of Licensed Products 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 U.S. Dollars under Section 4.4; and the royalties payable in U.S. Dollars.

When the laws or regulations of any country prohibit both the transmittal and deposit of royalties on sales in such country, royalty payments shall be suspended for as long as such prohibition is in effect and as soon as such prohibition ceases to be in effect, all royalties that SG would have been under an obligation to transmit or deposit but for the prohibition shall forthwith be deposited or transmitted to the extent allowable.

4.6 Financial Record Keeping and Review.

(a) SG Records. After the First Commercial Sale, SG shall keep for at least [***] ([***]) [***] following the end of the calendar year to which they pertain records of all sales of Licensed Products, in sufficient detail to permit GNE to confirm the accuracy of SG’s royalty calculations.

In every case the accountant must have previously entered into a confidentiality agreement with both Parties substantially similar to the confidentiality provisions of Section 10 and limiting the disclosure and use of such information to authorized representatives of the Parties and the purposes germane to this Section 4.6. Results of any such review shall be made available to both Parties. If any review reveals a deficiency in the calculation of royalties resulting in any underpayment by SG, SG shall promptly pay GNE the amount remaining to be paid (plus interest thereon at a rate equal to [***] percent ([***]) over the [***] as reported by [***] from time to time), and if such underpayment is by [***] percent ([***]%) or more, SG shall pay all costs and expenses of the review.

(b) Upon any termination of this Agreement by SG under Section 11.3, the licenses granted by GNE to SG in Section 2 shall thereafter automatically become perpetual; provided, however that SG shall continue to pay to GNE, for the remainder of the Term for each Licensed Product, royalties as set forth in Section 4.

(c) Upon any termination of this Agreement by GNE under Section 11.2 or 11.3, the licenses granted by GNE to SG in Section 2 shall terminate and SG, at GNE’s request, shall return to GNE all Materials and Technology.

(d) Any sublicense permitted under this Agreement, to the extent it is consistent with the rights and obligations due GNE hereunder, shall survive termination of this Agreement and be deemed a direct license from GNE provided that (i) the sublicensee is not in material

breach of the terms of its sublicense at the time of such termination, (ii) upon termination of this Agreement, such sublicensee agrees in writing to be bound by all terms of this Agreement applicable to SG, and can reasonably show the capacity to comply with such terms to the same extent as if such sublicensee were an original party hereto, (iii) the obligations of GNE under such direct license shall not be greater than the obligations of GNE under this Agreement, and (iv) the scope of such direct license shall not be broader than the rights sublicensed by SG to such sublicensee.

12. General Provisions

12.1 No Partnership.

12.2 Assignments. Neither Party shall assign any of its rights or obligations hereunder except: (a) as incident to the merger, consolidation, reorganization or acquisition of stock or assets affecting substantially all of the assets or voting control of the assigning Party; (b) to any wholly owned subsidiary if the assigning Party remains liable and responsible for the performance and observance of all of the subsidiary’s duties and obligations hereunder; or (c) with the prior written consent of the other Party (which consent shall not be unreasonably withheld), provided, however, that assignment in the context of insolvency or bankruptcy of SG shall require prior written consent of GNE. This Agreement shall be binding upon the successors and permitted assigns of the Parties, and the name of a Party appearing herein shall be deemed to include the names of such Party’s successor’s and permitted assigns to the extent necessary to carry out the intent of this Agreement.

No waiver, modification or amendment of any provision of this Agreement shall be valid or effective unless made in writing and signed by a duly authorized representative of each of the Parties.

12.7 Severability. In the event any one or more of the provisions of this Agreement should for any reason be held by any court or authority having jurisdiction over this Agreement or either

of the parties to be invalid, illegal or unenforceable, such provision or provisions shall be validly reformed to as nearly as possible approximate the intent of the Parties and, if unreformable, shall be divisible and deleted in such jurisdiction; elsewhere, this Agreement shall not be affected so long as the Parties are still able to realize the principal benefits bargained for in this Agreement.

12.11 Force Majeure. Neither Party shall lose any rights hereunder or be liable to the other Party for damages or losses on account of failure of performance by the defaulting Party if the failure is occasioned by government action, war, earthquake, fire, explosion, flood, strike, lockout, embargo, act of God, or any other cause beyond the control of the defaulting Party, provided that the Party claiming force majeure has exerted all reasonable efforts to avoid or remedy such force majeure; provided, however, that in no event shall a Party be required to settle any labor dispute or disturbance.
