 business combination with QT Imaging, which resulted in QT Imaging becoming a wholly-owned subsidiary of the Company. QT Imaging is a medical device company founded in 2012 and engaged in the research, development, and commercialization of innovative body imaging systems using low energy sound. We believe that medical imaging is critical to the detection, diagnosis, and treatment of disease and that it should be safe, affordable and accessible. Our goal is to improve global health outcomes through the development and commercialization of imaging devices that address critical healthcare challenges with accuracy and precision.

#### Products and Services
The Company currently offers two products: QT Breast Scanner and QTviewer®.

QT Breast Scanner is a fixed, mechanical scanner used to evaluate the breast without the use of either ionizing radiation or compression associated with mammography, or the contrast dyes (as environmentally impactful gadolinium etc.) injections required for breast MRI. With the QT Breast Scanner, the patient lies comfortably on a table which contains an opening through which the breast is placed in a warm water bath (see Image 1) and gently immobilized using a magnetic retention pad fixed to a magnetic rod. The QT Breast Scanner differs from the handheld ultrasound used in breast imaging in that it utilizes reflection and transmission data from low-frequency sound waves, providing a significant increase in diagnostic information using the speed of sound characteristics of the breast and acquiring in true 3D a very accurate rendering of the breast tissue. The QT Breast Scanner provides sub-millimeter, high-definition, image resolution enabling identification of normal and abnormal breast structures and the accurate depiction of the precise shape and location of findings. The technology uniquely quantifies breast density using ratio of breast fibroglandular tissue volume (FGV) to total breast volume (TBV) transmission and reflection images’ information of patient’s breast to further personalize a patient’s management recommendations. Surface-to-volume ratios and volumetric doubling time growth rate characteristics can be calculated to determine significance of lesions and improve specificity of the ultrasound.

The QT Breast Scanner creates true 3D images of the patient’s breast viewable in the Quantitative Transmission Ultrasound Viewer (known as QTviewer®), a software product designed for healthcare professionals to view the transmission (speed of sound) and reflection images. This application can display correlated Digital Imaging and Communications in Medicine (“DICOM®”) images in multiple orientations (coronal, sagittal, and axial). QTviewer can manipulate
