DE-FOA-0001817.

The primary mission of the Office of Nuclear Energy (NE) is to advance nuclear power as a resource capable of meeting the nation's energy, environmental, and national security needs. This is accomplished by resolving technical, cost, safety, proliferation resistance, and security barriers through research, development, and demonstration, as appropriate. The development of improved advanced nuclear reactor designs and technologies, as well as improvements in the operation of the existing domestic fleet of nuclear power plants, is the most important aspect of assuring that nuclear power will be a viable option for the United States (U.S.) energy needs for generations to come.

The fundamental premise behind this FOA is to provide a direct vehicle to support innovative, domestic nuclear industry-driven designs and technologies that have high potential to improve the overall economic outlook for nuclear power in the U.S. The investment provided by the Government will accelerate development of these designs and technologies so that the existing domestic fleet of nuclear power plants remains viable and the most mature new, advanced U.S. designs can be deployed as early as mid-to-late 2020s, and be globally competitive. These advanced reactor designs and technologies will further the state of the U.S. commercial nuclear capability by improving the competitiveness of nuclear power and promoting its continued contribution to meeting our nation’s economic, energy security, and environmental challenges.

The FOA is envisioned to provide support for

The revitalization and expansion of the U.S. nuclear industry by encouraging growth of a pipeline for advanced nuclear reactors, specifically through the employment of key private-public partnerships.

The objective of this FOA is to support innovation and competitiveness of the U.S. Continued ...

NONDISCLOSURE AGREEMENT BETWEEN X-ENERGY AND CENTRUS DATED MAY 5, 2017, AS AMENDED JANUARY 18, 2018

NONDISCLOSURE AGREEMENT

This Agreement, effective as of May 5, 2017 (the "Effective Date"), made by and between X Energy, LLC having a principal place of business at 0000 Xxxxxxxxx Xxxx, Xxxxx 000, Xxxxxxxx,x XX 00000 ("X Energy"), and Centrus Energy Corp. having a principal place of business at 0000 Xxxxxxxxx Xx., Xxxxx 000, Xxxxxxxx, XX 00000 ("Centrus Energy") (each referred to herein as a "Party").

It is anticipated that the disclosing Party (the "DISCLOSER") may from time to time disclose to the receiving Party (the "RECIPIENT") certain technical and/or business information which the DISCLOSER regards as proprietary and/or confidential. The purpose of this Agreement is to set forth the terms and conditions under which such information will be maintained in confidence by the RECIPIENT. In consideration of DISCLOSER entering into discussions with RECIPIENT about DISCLOSER potentially retaining RECIPIENT to perform services, RECIPIENT agrees as follows:

1. "Proprietary Information," as used herein, shall mean non-public technical and/or business information which is disclosed by the DISCLOSER to the RECIPIENT during the term of this Agreement and which DISCLOSER regards as proprietary and/or confidential.

2. DISCLOSER will xxxx any technical Proprietary Information that can be marked (such as in written form) with a "Proprietary," "Confidentia,l" or similar legend. DISCLOSER will not xxxx any financial/business Proprietary Information because such information in written or other tangible form will be presumed to be proprietary and/or confidential. RECIPIENT will treat all technical or financial/business information disclosed in oral form by DISCLOSER (such as during oral discussions) as Proprietary Information unless RECIPIENT confirms with DISCLOSER in writing that the information is not Proprietary Information.

3. RECIPIENT agrees that it shall retain such Proprietary Information in strict confidence, making no commercial uses of such Proprietary Information. The RECIPIENT agrees to use the same care and discretion as the RECIPIENT uses with respect to similar information of its own, but not less than reasonable care, to avoid unauthorized disclosure, publication, dissemination or use of Proprietary Information received hereunder.

4. The primary contact person for each Party, for the purpose of coordinating the flow of Proprietary Information, and for disclosure authorization, shall be:

For: X Energy, LLC Technical: Xxxx Xxxxxxx Contractual: Xxx Xxxxxx

For: Centrus Energy Corp. Technical:    Xxxxx X Xxxxxx Contractual: Xxxxx X Xxxxxx

5. RECIPIENT covenants and agrees that it will receive and use the Proprietary Information only for the authorized uses identified by the DISCLOSER ("Authorized Uses").

6. RECIPIENT agrees that it shall not disclose Proprietary Information to any third party, except to those of RECIPIENT's employees (plus, employees of any parent, affiliate or subsidiary), directors, officers, managers, professional advisors (including, but not limited to, lawyers, bankers, financial

consultants, and accountants), or creditors or guarantors (collectively, the "Representatives") who (i) have a bona fide need to know the Proprietary Information; (ii) are advised of the proprietary nature of the information; and (iii) except where such Representatives are U.S. government agencies, are bound, through a written agreement, to the terms of this Agreement or by a legally enforceable code of professional responsibility to protect the confidentiality of the Proprietary Information, without the express written authorization of an officer of the DISCLOSER. RECIPIENT further agrees that RECIPIENT will require each employee having access to Proprietary Information to agree to be bound by the terms of this Agreement prior to the disclosure of Proprietary Information to that employee. Notwithstanding the foregoing, In the event that a RECIPIENT is required by law, rule, regulation, legal process, court order, administrative demand or appropriate governmental authority to disclose the DISCLOSER'S Proprietary Information (whether on a confidential, privileged or other basis), the RECIPIENT shall, to the extent permitted by law, immediately notify the DISCLOSER and, upon request, cooperate with the DISCLOSER'S counsel to seek relief from the requested disclosure or to secure confidential treatment and minimization of the Proprietary Information to be disclosed. To the extent permitted by applicable law, the DISCLOSER shall have the right to take immediate possession of the Proprietary Information disclosed to RECIPIENT to revise such Proprietary Information to minimize its disclosure.

7. RECIPIENT shall not be responsible for disclosure of any Proprietary Information if such information (as supported by RECIPIENT's written records):

(i) Is or was publicly available at the time it was disclosed or is subsequently made available to the general public without restriction by the DISCLOSER or by disclosure by RECIPIENT in violation of this Agreement;

(ii) is furnished by the DISCLOSER to the U.S. Government with unlimited rights;

(iii) was known to or possessed by RECIPIENT at the time of disclosure;

(iv) was independently developed by RECIPIENT or RECIPIENT's employees or third parties;

(v) is used or disclosed with the prior written consent of the DISCLOSER; or

(vi) becomes known to RECIPIENT, on a non-confidential basis from a source other than DISCLOSER, without breach of an obligation of confidentiality or this Agreement by RECIPIENT.

8. The RECIPIENT shall only make such copies of the Proprietary Information as are reasonable and necessary in carrying out the Authorized Uses. Any such copies shall retain the proprietary markings, as applicable, from the original. The RECIPIENT shall promptly return or destroy all such copies to the DISCLOSER upon request, with the exception of one legal copy, which may be retained for archive purposes only. The RECIPIENT shall maintain the confidentiality of all Proprietary Information with regard to any copies.

9. Upon discovery of any inadvertent disclosure or use, the RECIPIENT shall notify DISCLOSER immediately and shall take all reasonable measures to prevent future inadvertent disclosure or use.

10. In the event of any breach of this Agreement, DISCLOSER may suffer irreparable harm and have no adequate remedy at law. In such event or the threat of any such event, DISCLOSER will be entitled to seek equitable relief, including but not limited to injunctive relief or specific performance, in addition to reasonable monetary damages, if any. The undersigned agree that the prevailing Party in any action brought to enforce the legal rights provided herein shall be entitled to full reimbursement of its costs (including reasonable attorneys' fees) in such action. RECIPIENT also agrees to waive any requirement for the securing or posting of any bond by the DISCLOSER in an action seeking such a remedy.

11. The protections afforded to the Confidential Information and Confidential Materials under this Agreement are in addition to, and not in lieu of, the protections afforded under any applicable trade secrets laws, including the Uniform Trade Secrets Act.

12. RECIPIENT acknowledges that this Agreement is subject to compliance with applicable United States laws, regulations, and/or orders. These laws, regulations, and orders include, but are not limited to, those that relate to the export of nuclear materials, equipment, software, and technology, such as the

U.S. Department of Energy ("DOE") regulations found in 10 C.F.R. Part 810, the U.S. Nuclear Regulatory Commission regulations in 10 C.F.R. Part 110, and the U.S. Department of Commerce's Export Administration Regulations found in 15 C.F.R. Part 730 et seq., as may be amended (collectively, "Export Control Laws").

(i) RECIPIENT agrees to comply with all Export Control Laws. RECIPIENT shall not export, reexport, transfer or retransfer, directly or indirectly, any Proprietary Information, except as permitted by such Export Control Laws.

(ii) Notwithstanding anything to the contrary in this Agreement, and in order to ensure compliance with Export Control Laws, RECIPIENT shall not, absent prior written approval by DISCLOSER:

a. use, directly or indirectly, Proprietary Information in any application involving a military use, missile technology, nuclear proliferation/nuclear explosive device, or chemical and biological weapons proliferation, and;

b. disclose or furnish Proprietary Information to any Foreign Nationals who are of a different nationality than the RECIPIENT (including RECIPIENT's employees who are of a different nationality than RECIPIENT, as applicable). For purposes of this paragraph, "Foreign National" means any person who is neither a U.S. citizen, a "Lawful Permanent Resident" (i.e., Green Card holder, 8 USC§ 1101(a)(20)), nor other "Protected Individual" under the Immigration and Naturalization Act (8 USC

§1324b(a)(3)) designated an asylee, refugee, or a temporary resident under amnesty provisions. A Foreign National also means any foreign corporation, business association, partnership, or any other entity or group that is not incorporated to do business in the U.S. This restriction applies to written and oral information and guidance which may be provided by DISCLOSER and applies to any information provided by any contractor, or subcontractor to DISCLOSER or any other person acting on behalf of DISCLOSER.

(iii) All tangible objects, such as drawings, reports, programs or documents, which constitute and/or contains or may contain Export Controlled Information shall be marked "Export Controlled Information" or "Information Contained Within May Contain Export Controlled Information" or such other markings as required or permitted by DOE guidance. Markings inadvertently omitted from export controlled Proprietary Information when disclosed to a person or entity shall be applied by such person or entity promptly when requested by the DISCLOSER, and such export controlled Proprietary Information shall thereafter continue to be treated as export controlled information under the terms of this Agreement.

13. In accordance with the Defend Trade Secrets Act of 2016, any individual performing work for Centrus, whether as an individual, contractor or consultant, will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (a) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. Further, if such an individual files a lawsuit for retaliation by an employer for reporting a suspected violation of law, he or she may disclose the employer's trade secrets to his or her attorney and use the trade secret information in the court proceeding if such individual: (x) files any document containing the trade secret under seal; and (y) does not disclose the trade secret, except pursuant to court order. Except to the extent notice of the foregoing immunities has already been given to such individuals, X Energy shall notify its employees, contractors or employees receiving Proprietary Information under this Agreement, of such immunities.

14. These provisions are consistent with and do not supersede, conflict with, or otherwise alter the employee obligations, rights, or liabilities created by existing statute or Executive order relating to (1) classified information, (2) communications to Congress, (3) the reporting to an Inspector General of a violation of any law, rule, or regulation, or mismanagement, a gross waste of funds, an abuse of authority, or a substantial and specific danger to public health or safety, or (4) any other whistleblower protection. The definitions, requirements, obligations, rights, sanctions, and liabilities created by controlling Executive orders and statutory provisions are incorporated into this agreement and are controlling.

The limitation above shall not contravene requirements applicable to Standard Form 312, Form 4414, or any other form issued by a Federal department or agency governing the nondisclosure of classified information. {Note: This Paragraph added effective January 18, 2018}
