On September 9, 2022, Jason F. Cole, Chief Strategy and Financial Officer, principal financial officer and principal accounting officer of bluebird bio, Inc. (the “Company”), provided notice of his resignation from the Company, effective October 14, 2022.

Under the Separation Agreement, Mr. Cole will continue to receive his salary and benefits and will continue to vest in his outstanding equity awards through the Separation Date. Following the Separation Date, Mr. Cole will continue to receive his base salary for a period of twelve months. If he elects to continue his group healthcare benefits, to the extent authorized by and consistent with COBRA, the Company will pay the monthly employer contribution until (A) the later of October 31, 2023, or the termination date of the Consulting Agreement (as defined below), or (B) the date Mr. Cole becomes eligible for insurance through another employer or otherwise becomes eligible for insurance through another employer or otherwise becomes ineligible for COBRA. In addition, following the Separation Date, Mr. Cole will be a consultant to the Company on certain strategic matters for a period of six months pursuant to a Consulting Agreement entered into on September 12, 2022 (the “Consulting Agreement”). Under the Consulting Agreement, Mr. Cole is entitled to an hourly rate for his consulting services based on his 2022 base salary, and his outstanding equity awards will continue to vest during the term of the Consulting Agreement.

The Company expects Katherine Breedis will be appointed to serve as interim Chief Financial Officer, principal financial officer and principal accounting officer upon effectiveness of Mr. Cole’s resignation from the Company.
