We want to be the first to inform you that the HemoSense board of directors has accepted an offer for our company to be acquired by Inverness Medical Innovations, a leading manufacturer and distributor of healthcare diagnostic equipment. You may already be familiar with Inverness as a representative of their products. The attached news release describing the acquisition was issued by Inverness this evening.

The acquisition will take a few months to close; during that time we expect no change or disruption in our relationship with your organization, and look forward to providing the service and support you have come to expect from HemoSense.

We believe this transaction is a very positive development for HemoSense, and an excellent strategic fit. Through our existing distributor relationships, the INRatio® system will continue to be offered to professional healthcare providers and patients worldwide as we complete this transition and beyond.

Letter to Employees

With a sense of great pride in our collective accomplishments since HemoSense was founded in early 1997, I would like to inform you that our board of directors has accepted an offer for HemoSense to be acquired by Inverness Medical Innovations, a Massachusetts-based manufacturer of healthcare diagnostic equipment. The attached news release describing the details of the acquisition was issued by Inverness this evening.

Briefly, Inverness intends to acquire HemoSense for approximately $200 million, in an all stock transaction. The transaction requires approval by a majority of HemoSense stockholders, and is expected to close within approximately three months. In the short term, it will be business as usual at HemoSense.

The HemoSense executive team, along with our board of directors, believes this transaction is the right step for our Company, and will provide greater growth opportunities for our products. From a strategic perspective, the combination of HemoSense and Inverness is solid. As you may know, through their acquisition of QAS earlier this year, Inverness already distributes the INRatio system. They are a strong believer in the importance and future of the coagulation testing market, and acquiring HemoSense is expected to help accelerate their growth and improve their competitive position.

I suspect you will have questions about what this development means for you and the Company going forward. Please join Bill Dippel, Gordon Sangster, Tim Still, Doug Rundle and me at 9:00 a.m (PST) Tuesday morning in the sales and marketing training room or via conference line (800-483-6698 / Passcode: 317182) where we will give you more detail about Inverness and the acquisition.

I’m very proud of what we have accomplished at HemoSense. Our operations have grown and our financial results have improved consistently for more than four years. Yet more significantly, we have developed an important medical diagnostic that contributes to improved health for thousands of people around the world. As part of Inverness, our products will continue to play an important role to an ever-greater number of people.

As we enter this new chapter in our Company’s evolution, I want to emphasize that each of you has made important contributions to our success. I know we will continue to support warfarin patients and their related healthcare professionals, grow our business and continue to go FULL SPEED AHEAD in the weeks and months to come.

I thank you for your hard work, for your dedication and for your friendship.

Best regards,

Jim Merselis

President and CEO
