Neither SC Health's nor Rockley Photonics' independent auditors have studied, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this document, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this Investor Presentation.
