Dear Alec:

On behalf of T2 Biosystems, Inc., (the “Company”) I am delighted to make this offer of employment to you to join us in the role of Senior Director, Program Management for the Company beginning on April 18, 2016.

At T2 Biosystems, our mission is to lower mortality rates, improve patient outcomes and reduce the cost of healthcare by empowering medical professionals to make targeted therapeutic treatment decisions earlier.  To this end, you are joining us at a very exciting stage in our development as a Company!  In September 2014, we received FDA clearance to sell our first two products, the T2Dx Instrument and T2Candida Panel, which provide sensitive detection of specific sepsis-causing pathogens directly from a whole blood specimen in 3-5 hours versus 2-5 days for competitive detection systems.  Published data has demonstrated that this improvement in time to detection may reduce the current mortality rate of 40% for those infections to 11%.  We are truly excited to bring this product to market.

This speed and detection capability is made possible by our proprietary magnetic resonance-based diagnostic technology platform, called T2MR, which has been in development since our inception in 2006.  Our next two clinical applications for our T2MR technology will target bacterial sepsis and hemostasis, areas of significant unmet medical need where existing therapies could be more effective with improved diagnostics.

Alec, we are excited to extend this offer of employment to you.  We think you can help us fulfill our mission and we believe you’d be a great fit for our team.  To kick things off, you will find all of the pertinent information related to our offer of employment in the attached pages.  Please read the offer carefully and, if it is acceptable, sign and return one copy to my attention (PDF copy is fine).    

If you have any questions, please do not hesitate to contact me at (781) 457-1220 or email at jmcdonough@t2biosystems.com.  We are looking forward to having you on our team!

Sincerely,

/s/ John McDonough
