UNITED STATES LAWS:

Page 4 of 22


CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS EXHIBIT MARKED BY [***] HAS BEEN OMITTED BECAUSE IT IS BOTH NOT MATERIAL AND IS THE TYPE OF INFORMATION THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL

4.1Licensee understands that the Licensed Subject Matter may have been developed under a funding agreement with the Government of the United States of America and, if so, that the Government may have certain rights relative thereto. This Agreement is explicitly made subject to the Government’s rights under any agreement and any applicable law or regulation. If there is a conflict between an agreement, applicable law or regulation and this Agreement, the terms of the Government agreement, applicable law or regulation shall prevail.

Specifically, This Agreement is subject to all of the terms and conditions of Title 35 United States Code sections 200 through 204, including an obligation that Licensed Product(s) sold or produced in the United States be “manufactured substantially in the United States,” and LICENSEE agrees to take all reasonable action necessary on its part as licensee to enable LICENSOR to satisfy its obligation thereunder, relating to Invention(s).

4.2It is understood that LICENSOR is subject to United States laws and regulations controlling the export of technical data, computer software, laboratory prototypes and other commodities (including the Arms Export Control Act, as amended and the Export Administration Act of 1979), and that its obligations hereunder are contingent on compliance with applicable United States export laws and regulations. The transfer of certain technical data and commodities may require a license from the cognizant agency of the United States Government and/or written assurances by LICENSEE that LICENSEE shall not export data or commodities to certain foreign countries without prior approval of such agency. LICENSOR neither represents that a license shall not be required nor that, if required, it shall be issued.

5.

PATENT PROTECTION AND INFRINGEMENT:

5.1LICENSOR, during the term of this Agreement, is responsible for the filing and the prosecution of all patents and applications where LICENSEE shall reimburse LICENSOR for all payments within thirty (30) days of invoice. LICENSOR shall keep LICENSEE fully apprised on the status of all Patent Rights and shall provide LICENSEE the opportunity to make comments and suggestions on all decisions relating to

Page 5 of 22


CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS EXHIBIT MARKED BY [***] HAS BEEN OMITTED BECAUSE IT IS BOTH NOT MATERIAL AND IS THE TYPE OF INFORMATION THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL

the prosecution of the Patent Rights (e.g., office actions). LICENSOR shall in good faith consider incorporating such comments and suggestions unless such incorporation would be contrary to the purposes of this Agreement.

5.2LICENSEE shall promptly notify LICENSOR in writing of any claim of Patent Rights infringement which may be asserted against LICENSEE or LICENSOR, its Affiliates and any sublicensees because of the manufacture, use, promotion and sale of Products.

5.3LICENSEE shall pay to LICENSOR a license issue fee in the amount of [$50,000] and past patent fees in an amount of [$15,796.58] incurred as of 10/22/2010 within thirty (30) days of the Effective Date. LICENSEE shall also pay to LICENSOR all future patent fees within thirty (30) days after the LICENSEE has received the invoice from LICENSOR pertaining to such future patent fee.

5.4LICENSEE will defend, indemnify and hold harmless LICENSOR, its trustees, officers, directors, employees and its Affiliates against any and all judgments and damages arising from any and all third party claims of Patent Rights infringement which may be asserted against LICENSOR, and Affiliates because of the manufacture, use, promotion and sale of Licensed Products except for the use of Licensed Materials, Licensed Products and/or Licensed Processes by Licensor pursuant to section 2.3 of this Agreement. LICENSEE will bear all costs and expenses incurred in connection with the defense of any such claims or as a result of any settlement made or judgment rendered on the basis of such claims. LICENSOR shall have no further liability to LICENSEE for any loss or damages LICENSEE may incur as a result of the invalidity of LICENSOR’S Patent Rights. LICENSOR will have the right, but not the obligation to retain counsel at its expense in connection with any such claim. LICENSOR at its option, shall have the right, within thirty days after commencement of such action, to intervene and take over the sole defense of the action at its own expense.

5.5Upon learning of any infringement of Patent Rights by third parties in any country, LICENSEE and LICENSOR will promptly inform each other, as the case may be, in writing of that fact and will supply the other with any available evidence pertaining to the infringement. LICENSEE at its own expense, shall have the option to

Page 6 of 22


CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS EXHIBIT MARKED BY [***] HAS BEEN OMITTED BECAUSE IT IS BOTH NOT MATERIAL AND IS THE TYPE OF INFORMATION THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL

take whatever steps are necessary to stop the infringement at its expense and recover damages therefore. If requested by LICENSEE, LICENSOR will join in any legal actions enforcing or defending the Patent Rights against third parties deemed necessary or advisable by LICENSEE to prevent or seek damages, or both, from the infringement of the Patent Rights provided that LICENSEE funds all costs associated with such actions, using counsel mutually acceptable to LICENSEE and LICENSOR, and indemnifies and holds LICENSOR harmless with respect to any claims or damages made against or sustained by LICENSOR in connection with such involvement. In the event that LICENSOR and LICENSEE mutually bring suit, costs and expenses shall be borne by LICENSEE, and any recovery shall be shared by the parties as if such infringing sales were Net Sales. In any event, no settlement, consent, judgment or other voluntary final disposition of the suit may be entered into without the consent of LICENSOR, which shall not be unreasonably withheld. In the event LICENSEE does not take steps to stop the infringement, LICENSOR shall have the right to bring suit at its own expense. In such event, financial recoveries will be entirely retained by LICENSOR.

5.6LICENSOR shall have no responsibility with respect to LICENSEE’S own trademarks and trade name, and LICENSEE in respect to the use thereof will defend, indemnify and hold harmless LICENSOR against any and all third party claims.

6.

CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS EXHIBIT MARKED BY [***] HAS BEEN OMITTED BECAUSE IT IS BOTH NOT MATERIAL AND IS THE TYPE OF INFORMATION THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL

The minimum royalty shall be paid for each year in which this Agreement is in effect. The minimum royalty payment shall be due on or before December 31 of the calendar year. Any minimum royalty paid in a calendar year will be credited against the earned royalties for that calendar year. It is understood that the minimum royalties will be applied to earned royalties on a calendar year basis, and that sales of Licensed Products and/or Licensed Processes requiring the payment of earned royalties made during a prior or subsequent calendar year shall have no effect on the annual minimum royalty due LICENSOR for other than the same calendar year in which the royalties were earned.

(c)

LICENSEE agrees to pay to LICENSOR as earned royalties a royalty calculated as a percentage of LICENSEE’s Net Sales of Licensed Products which, if not for this Agreement, would infringe the Patent Rights, in accordance with the terms and conditions of this Agreement. The royalty is deemed earned as of the earlier of the date the Licensed Product and/or Licensed Process is actually sold and paid for, the date an invoice is sent by LICENSEE, or the date a Licensed Product and/or Licensed Process is transferred to a third party for any promotional reasons. The royalty shall remain fixed while this Agreement is in effect at a rate of [*****] of Net Sales.

(d)

For a sublicense, LICENSEE shall pay to LICENSOR an amount equal to [*****]of what LICENSEE would have been required to pay to LICENSOR had LICENSEE sold the amount of Licensed Products sold by the Sublicensee. In addition, if LICENSEE receives any fees, minimum royalties, or other payments in

Page 10 of 22


CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS EXHIBIT MARKED BY [***] HAS BEEN OMITTED BECAUSE IT IS BOTH NOT MATERIAL AND IS THE TYPE OF INFORMATION THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL

consideration for any rights granted under a Sublicense, and such payments are not based directly upon the amount or value of Licensed Products or Licensed Processes sold by the Sublicensee nor represent payment of costs to LICENSEE for a development program which LICENSEE is obligated to perform under such sublicense,, then LICENSEE shall pay LICENSOR [*****] of such payments.

(e)

[$100,000]

Upon completion of a phase 1 clinical trial

[$500,000]

By the earlier of May 31, 2022 or the approval of an NDA

(f)

In the event that licenses from third parties are required by LICENSEE in order to make, have made, use, sell, offer to sell or import any particular Licensed Product or Licensed Process, then the earned royalty which LICENSEE is obligated to pay LICENSOR under this Agreement shall be reduced by [*****] for each one dollar ($1.00) in royalties which Licensee is obligated to pay to third parties under such licenses, further provided, however,

Page 11 of 22


CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS EXHIBIT MARKED BY [***] HAS BEEN OMITTED BECAUSE IT IS BOTH NOT MATERIAL AND IS THE TYPE OF INFORMATION THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL

that the royalties payable to LICENSOR under this Section shall not be reduced to less than [*****]of the applicable Net Sales.

(g)

In the event that LICENSEE requires more than one license from the LICENSOR to make, have made for its use, sell, offer to sell or import any particular Licensed Product or Licensed Process as defined in sections 1.5 and 1.6, respectively, of this Agreement, then the combined earned royalties shall not exceed [*****]of Net Sales and any sublicense fees shall not exceed [*****] of what LICENSEE would have been required to pay to LICENSOR had LICENSEE sold the amount of Licensed Products sold by the Sublicensee.

8.2All payments shall be made hereunder in U.S. dollars; provided however, that if the proceeds of the sales upon which such royalty payments are based are received by the LICENSEE in a foreign currency or other form that is not convertible or exportable in dollars, and the LICENSEE does not have ongoing business operations or bank accounts in the country in which the currency is not convertible or exportable, the LICENSEE shall pay such royalties in the currency of the country in which such sales were made by depositing such royalties in LICENSOR’S name in a bank designated by LICENSOR in such country. Royalties in U.S. dollars shall be computed by converting the royalty in the currency of the country in which the sales were made at the exchange rate for U.S. dollars prevailing at the close of the business day of the LICENSEE’S quarter for which royalties are being calculated as published the following day in the Wall Street Journal (or, if it ceases to be published, a comparable publication to be agreed upon from time to time by the parties), and with respect to those countries for which rates are not published in the Wall Street Journal, the exchange rate fixed for such date by the appropriate United States governmental agency.

8.3In the event the royalties set forth herein are higher than the maximum royalties permitted by the law or regulations of a particular country, the royalty

Page 12 of 22


CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS EXHIBIT MARKED BY [***] HAS BEEN OMITTED BECAUSE IT IS BOTH NOT MATERIAL AND IS THE TYPE OF INFORMATION THAT THE REGISTRANT TREATS AS PRIVATE OR CONFIDENTIAL

payable for sales in such country shall be equal to the maximum permitted royalty under such law or regulation.

8.4In the event that any taxes, withholding or otherwise, are levied by any taxing authority in connection with accrual or payment of any royalties payable to LICENSOR under this Agreement, the LICENSEE shall have the right to pay such taxes to the local tax authorities on behalf of LICENSOR and the payment to LICENSOR of the net amount due after reduction by the amount of such taxes, shall fully satisfy the LICENSEE’S royalty obligations under this Agreement.

9.

DILIGENCE:

9.1LICENSEE shall use efforts at least sufficient to meet the requirements of the Bayh-Dole Act to manufacture, market and sell the Licensed Products in the Territory, and to create a demand for the Products.

9.2LICENSEE agrees to submit reports, upon LICENSOR’s request but no more than every 6 months as to its efforts to develop markets for the Licensed Products. Such reports shall include assurance by LICENSEE of its intent to actively develop commercial embodiments of Licensed Products and a summary of its efforts in this regard.

9.3Unless LICENSEE has introduced a Licensed Product into the commercial marketplace in one of the three major markets (European Union, Japan and the United States) or has made best efforts (for avoidance of doubt it will be presumed that LICENSEE has used best efforts if it has a Licensed Product in a phase III clinical trial) to achieve the same prior to December 31, 2020, LICENSEE agrees that LICENSOR may terminate this Agreement by providing LICENSEE ninety (90) advanced written notice of its intent to terminate this Agreement. In the event the payment of earned royalties, once begun and if any are due, ceases for more than two ( 2) calendar quarters, and LICENSEE fails to cure this breach within two (2) months after being provided written notice of same, LICENSOR may terminate this Agreement.

Each such report shall be accompanied by payment in full of the amount due LICENSOR in United States dollars calculated in accordance with Section 8.1 hereof.

10.2For a period of three (3) years from the date of each report pursuant to Paragraph 10.1, LICENSEE, shall keep records adequate to verify each such report and accompanying payment made to LICENSOR under this Agreement, and an independent certified public accountant or accounting firm selected by LICENSOR and acceptable to LICENSEE may have access, on reasonable notice during regular business hours, not to exceed once per year, to such records to verify such reports and payments. Such accountant or accounting firm shall not disclose to LICENSOR any information other than that information relating solely to the accuracy of, or necessity for, the reports and payments made hereunder. The fees and expense of the certified public accountant or accounting firm performing such verification shall be borne by LICENSOR unless in the event that the audit reveals an underpayment of royalty by more than [*****] percent, the cost of the audit shall be paid by LICENSEE.

11.
