Dear SculpSure Customer,

Earlier this week Hologic announced plans to the acquire Cynosure for $1.65 billion, which is expected to close in late March or early April 2017. Hologic is a global health care leader, and this strategic acquisition positions Cynosure to accelerate growth for its non-invasive body contouring offering.

Assuming this transaction closes as anticipated, Cynosure will become a wholly owned subsidiary of Hologic. This combination presents a tremendous opportunity for Cynosure and our customers. We will further our investments to drive growth of our leading products in the rapidly growing medical aesthetics market. Together we will strengthen support for our customers and focus on innovation to deliver market-leading products with proven clinical results.

Increasing our investment will allow Cynosure to provide a high level of support to you and deliver on key initiatives to help drive more patients to your practice.

SculpSure offers a true competitive advantage to other technologies in the $2 billion medical aesthetics market expected to grow at a low-double-digit rate over the next several years. Consumers will be looking to providers like you to offer the best solutions that will eliminate stubborn fat with no downtime or side effects in less time. Cynosure remains fully committed to our vision to be your long-term partner, and deliver your patients the best technology in non-invasive body contouring.

We thank you for your business and continued support.

Sincerely,

Douglas Delaney

Chief Commercial Officer

Cynosure
