agree, that all information submitted pursuant to this provision may be disclosed to the U.S. Government. This provision only applies if the Agreement involves research, including, without limitation, nonclinical research.

PUBLICATIONS AND PRESS RELEASES. Service Provider must obtain PARATEK’s approval before publicly disclosing any publication or press release relating to this Agreement or Service Provider’s performance under this Agreement.

U.S. GOVERNMENT REPORTING.

If PARATEK or the U.S. Government identifies any issues during the visit, Service Provider will prepare a report describing the issues and where applicable, identifying potential solutions. Solely with respect to audits or inspections initiated at the request of the U.S. Government, Service Provider will provide the report to PARATEK for review within twelve (12) business days of being notified of any issues. Once corrective action (if any) is taken in consultation with PARATEK, Service Provider will promptly provide PARATEK with a follow-up report.

PRIME CONTRACT AND QUALITY AGREEMENT. Service Provider will negotiate with PARATEK in good faith to make any revisions to this Agreement that may be necessary based on future modifications to the applicable PARATEK agreement(s) with the U.S. Government or any quality agreement negotiated between PARATEK and the U.S. Government.

U.S. GOVERNMENT DISPUTES. Any dispute between Service Provider and PARATEK arising from the U.S. Government’s actions under the applicable PARATEK agreement(s) with the U.S. Government, and for which PARATEK has recourse against the U.S. Government, will be resolved as follows notwithstanding any other dispute provisions in this Agreement:

Service Provider shall notify PARATEK of the dispute as soon as practicable, but in no event more than six months after Service Provider knew or should have known of the facts giving rise to such a dispute. Service Provider shall provide in the notice a written justification for and evidence supporting its position in the dispute and certify that it has a good faith basis to take this position.

Upon receiving a timely and complete notice from Service Provider, PARATEK will pursue relief under the Disputes clause in the applicable PARATEK agreement(s) with the U.S. Government by submitting a sponsored claim to the relevant U.S. Government contracting officer(s).

If Service Provider deems the contracting officer’s final decision in response to the sponsored claim to have an adverse effect on Service Provider’s position or rights, Service Provider and PARATEK will jointly determine in good faith whether to appeal the contracting officer’s final decision to the appropriate Board of Contract Appeals, the U.S. Court of Federal Claims, or any other forum that has jurisdiction over the contracting officer’s final decision. If Service Provider and PARATEK jointly agree to pursue such an appeal, Service Provider will be responsible for pursuing the appeal through PARATEK’s filings and will bear all expenses, including attorneys’ fees, arising from the appeal.

PARATEK will transfer any amounts that it receive s in a dispute with the U. S. Government to Service Provider to the extent that such amounts reflect recovery for any portion of a claim representing Service Provider’s damages. PARATEK’s payment of such amounts will constitute complete satisfaction of any liability that PARATEK may have to Service Provider under this Agreement in connection with such a claim. PARATEK will also have no liability to Service Provider in connection with a claim brought under this Section to the extent that the U.S. Government issues a final decision denying such a claim after the decision is no longer appealable. In addition, PARATEK will have no liability to Service Provider with respect to any dispute that Service Provider fails to timely raise under this

Section, except to the extent that PARATEK expressly agrees in writing to waive an applicable timeline.

It is the legal responsibility of Service Provider to ensure compliance with these executive orders and laws. This clause must be included in all subcontracts under this Agreement.

SECURITY INCIDENTS. Service Provider will provide PARATEK with notice within twenty- four hours of becoming aware of any security incident—including violation of Service Provider’s established security standards, compromise, intrusion, loss of or interference with security processes and procedures, and the loss or theft of PARATEK or U.S. Government property— relating to the work performed under this Agreement. Service Provider shall ensure that all software components that are not required for the operation and maintenance of the database/control system have been removed and/or disabled in such an event. Service Provider shall provide PARATEK with information appropriate to information and information technology software and service updates and/or workarounds to mitigate all vulnerabilities associated with the data associated with an incident and shall maintain an adequate level of system security. Service Provider will investigate security incidents to determine their cause, the extent, loss or compromise of sensitive program information, and corrective actions taken to prevent future incidents. The U.S. Government may direct that this Agreement be terminated in response to a severe security incident in which case PARATEK will be authorized to immediately terminate this Agreement and Service Provider will be solely entitled to receive an amount that it would be entitled to receive under FAR 52.249-2 if this Agreement were a prime contract with the U.S. Government.
